REFRIGERATOR

[Technical Field]
[0001]
The present invention relates to refrigerators configured to produce a high energy saving effect.

[Background Art]
[0002]
FIG. 18 is a cross-section view of a basic structure of a freezer compartment of a conventional refrigerator.
[0003]
As shown in FIG. 18  a gasket 12 is formed along the whole inner peripheral portion of a door 11. With an aim to prevent cool air from leaking outside  this gasket 12 is closely in contact with an abutting member 14 which is made of metal and formed on the front surface which is of a partition body 13 and abuts an abutting surface of the gasket 12.
[0004]
The refrigerator is configured to infuse  by using a fan 16  cool air generated by a cooler 15 provided on a rear portion of the main body from a discharge port 17 provided on a rear portion of a freezer compartment 25 to inside the refrigerator  and thereby to cool foods stored therein.
[0005]
As shown by arrows  the cool air cooling the foods is circulated by being forwarded to upper portions of storage cases 18 and 19  passed through the space between an inner wall of the door 11 and the storage cases 18 and 19 and through the space between the bottom surface of the storage case 19 and the bottom wall of a storage compartment  and returned from a return duct 21 to the cooler 15.
[0006]
Furthermore  a radiator pipe 23 is fixedly set up with an aim to prevent the cool air forwarded to the upper portions of the storage case 18 from cooling the front surface of the partition body 13 located between the freezer compartment 25 and an upper storage compartment 22 and thereby to prevent dew condensation from occurring on the front surface of the partition body 13 due to a difference between inside and outside temperatures. This radiator pipe 23 used here is a high-temperature coolant pipe in a freezing cycle system (not shown). Thus  the heat increases the temperature of the front surface of the partition body 13 to a high temperature. Although the heat prevents occurrence of dew condensation  the heat inevitably increases the temperature of air in the upper front portion of the freezer compartment 12 and reduces the cooling efficiency.
[0007]
In order to prevent this  a mechanism has been proposed in which a sealing member 24 shown by a two-dot chain line is provided in a space above the storage case 18 near the partition body 13 so as to prevent the cool air from flowing toward the gasket 12 (for example  see Patent Document 1).

[Summary of Invention]
[Technical Problem]
[0009]
The refrigerator configured as mentioned above includes the partition body having the sealing member which is for preventing cool air inside the storage compartment from being heated by heat exchange with the abutting member made of metal and is for preventing the cool air from flowing into the abutting member made of metal by abutting the storage case. However  cool air cannot be prevented when the sealing effect produced by the sealing member decreases with time. The cool air is heated by heat exchange with the abutting member made of metal and thus having a high temperature  resulting in a problem that the cooling efficiency is increased. Furthermore  adding such a sealing member produces another problem that the cost and the number of man hours for assembling are also inevitably increased.

[Solution to Problem]
[0010]
In order to solve the aforementioned problem  a refrigerator according to the present invention comprises: a main body having a heat insulation property; a partition body which partitions the main body into upper and lower storage compartments having mutually different temperature ranges; doors each of which opens and closes a corresponding one of the storage compartments partitioned by the partition body; and a prevention part formed by being defined by a structure of the partition body which prevents heat from penetrating at least one of the storage compartments.

[Advantageous Effects of Invention]
[0011]
A refrigerator according to the present invention includes a prevention part defined by a structure of a partition body which vertically partitions a main body of the refrigerator. The structure makes it possible to prevent heat penetration from outside and heat exchange between storage compartments. Therefore  the present invention can provide such a refrigerator which can achieve an increased cooling efficiency and a reduced electric power consumption.

[Description of Embodiments]
[0013]
A first aspect of the present invention comprises: a main body having a heat insulation property; a partition body which partitions the main body into upper and lower storage compartments having mutually different temperature ranges; doors each of which opens and closes a corresponding one of the storage compartments partitioned by the partition body; and a prevention part formed by being defined by a structure of the partition body which prevents heat from penetrating at least one of the storage compartments.
[0014]
In this way  it is possible to provide the refrigerator which is capable of preventing heat penetration from outside the refrigerator and heat exchange between the storage compartments each of which has a different temperature range  and reducing the electric power consumption.
[0015]
The present invention may further comprise: an abutting member which is made of metal and disposed on the front surface of the partition body in a direction toward the doors; and a gasket disposed between the abutting member and each of the doors to increase airtightness of the storage compartments  wherein the prevention part is disposed at least one of above and below the abutting member.
[0016]
In this way  it is possible to provide the refrigerator which is capable of preventing heat penetration from the abutting member which is made of metal and in contact with outside air to inside the refrigerator  and reducing the electric power consumption.
[0017]
In addition  the prevention part may be rectangular in shape at a portion positioned near outside of the refrigerator.
[0018]
With this  it is possible to prevent the whole appearance quality at the time of opening and closing the door of the refrigerator from degrading for the reason that the front surface portion of the partition body which defines the space is more noticeable than the peripheral structure.
[0019]
In addition  the partition body may include: an upper partition board and a lower partition board; and a vertical interfit part which fixes the upper partition board and the lower partition board in a vertical direction.
[0020]
With this  it is possible to secure vertical interfit of the assembled members which define the space  and thereby to secure the heat insulation property and increase the appearance quality.
[0021]
In addition  the partition body may include: an upper partition board and a lower partition board; and a depth interfit part which fixes the upper partition board and the lower partition board in a depth direction.
[0022]
With this  it is possible to secure  in the depth direction  interfit of the assembled members which define the space  and thereby to secure the heat insulation property and increase the appearance quality.
[0023]
The prevention part may include a foam heat insulation material filled in an inside of the prevention part.
[0024]
In this way  it is possible to provide the refrigerator including the prevention part which produces a high energy saving effect.
[0025]
In addition  the partition body may include an air hole which connects an inner space and an outside of the partition body.
[0026]
With this  the flexibility of the foam heat insulation material infused into the space is secured  and thus it is possible to securely fill the foam heat insulation material inside the whole space. This enables stable mass production of such refrigerators providing a high energy saving effect. Therefore  it is possible to reduce differences between products.
[0027]
In addition  the partition body may include a heat insulation material storage space for storing a surplus foam heat insulation material in a proximity of the air hole.
[0028]
With this  it is possible to actively lead excess foam heat insulation material to a place which is difficult to see as the appearance. Thus  it is possible to prevent the appearance quality from degrading due to overflow of the foam heat insulation member into the outside of the outer case and the inside of the storage compartments.
[0029]
In addition  the prevention part may form a closed space at a connection part between the partition body and the main body.
[0030]
With this  a space is formed in which no gases are convected between the storage compartments each having the different temperature range. The air flowing in the gap between the partition body and the main body serves as a barrier  and thus it is possible to prevent heat penetration between the storage compartments.
[0031]
The present invention may further comprise: an inner case hole which connects an inner space of the partition body and an inner space of the main body at a surface on which the partition body and the main body are in contact with each other; and a foam heat insulation material filled in the inner space of the partition body via the inner case hole when the foam heat insulation material is filled in the inner space of the main body.
[0032]
With this  the foam heat insulation material infused from the inner case serves as a barrier against the air flowing in the gap  and thus it is possible to further increase the heat insulation effect and thus prevent the heat penetration.
[0033]
In addition  the prevention part may be a board-shaped rib which protrudes from a peripheral portion of the partition body to form a space by abutting an inner surface of the main body.
[0034]
In this way  it is possible to easily foam the space  and to form a more complex-shaped space. Various kinds of shapes are possible to prevent heat penetration.
[0035]
In addition  the prevention part may form a plurality of closed spaces inside the partition body.
[0036]
In this way  it is possible to form a closed space in a space which cannot be structured using only the inner case of the main body  and to increase the heat penetration prevention effect.
[0037]
The prevention part may form a plurality of closed spaces.
[0038]
These closed spaces increase resistance by the barrier against the air flowing in the gap. Therefore  it is possible to increase the heat penetration prevention effect.
[0039]
In this way  the prevention part may include protrusion portions which interfit with portions of the inner case.
[0040]
With this  it is possible to partially close the gap between the partition body and the inner case  and thereby to prevent movement of the air flowing in the gap. Therefore  it is possible to increase the effect of preventing the heat penetration between the storage compartments.
[0041]

[0043]
As shown in FIG. 1  a main body 101 of a refrigerator 100 is composed of an outer case 102 mainly generated using a steel plate and an inner case 103 formed using a resin such as ABS. A foam heat insulation material such as rigid urethane foam is filled between the outer case 102 and the inner case 103. The refrigerator 100 is insulated from the surroundings mainly by the main body 101. The main body 101 is partitioned into a plurality of storage compartments. A refrigerator compartment 104 is disposed at the uppermost part of the main body 101 as a storage compartment  a vegetable compartment 105 is disposed below the refrigerator compartment 104 as a storage compartment  and a freezer compartment 106 is disposed at the lowermost part of the main body 101 as a storage compartment.
[0044]
The front openings of the respective storage compartments are closed by doors 117  118  and 119 in an openable manner.
[0045]
The refrigerator compartment 104 has a lower limit temperature as a temperature for refrigerating without freezing  and is set to temperatures normally within a range inclusively from 1 to 5 degrees Celsius. The vegetable compartment 105 is set to a temperature equal to or slightly higher than that of the refrigerator compartment 104  that is  to the temperature is normally within a range inclusively from 2 to 7 degrees Celsius. The freezer compartment 106 is set to a temperature within a freezing temperature range for freezing  and is set to a temperature that is normally within a range inclusively from -22 to -15 degrees Celsius. It is to be noted that the freezer compartment 106 is set at a low temperature such as -30 or -25 degrees Celsius in order to increase a freezing storage state. In addition  the vegetable compartment 105 is switched to have a temperature range for a freezing compartment  and can be set to -18 degrees Celsius. However  the vegetable compartment 105 is described as a vegetable compartment in the descriptions below.
[0046]
A mechanical room 107 is provided at an area behind the freezer compartment 106 located at the lowermost part of the main body 101. The mechanical room 107 houses high-pressure side components in a freezing cycle system such as a compressor 108  and a drier for removing moisture (not shown).
[0047]
As shown in FIG. 2  a cooling room 109 which generates cool air is provided behind the freezer compartment 106. A depth surface partition wall 110 having a heat insulation property is provided between the freezer compartment 106 and the cooling room 109. The depth surface partition wall 110 is intended to form a path for carrying cool air to the respective compartments and to partition the compartments in an insulated manner. The cooling room 109 includes a cooler 111 fixedly set up. A cooling fan 112 is provided above the cooler 111 so as to send air cooled by the cooler 111 using a forced convection method to the refrigerator compartment 104  the vegetable compartment 105  and the freezer compartment 106. The cooler 111 includes  in the lower space  a radiant heater 113 generated using a glass tube and for defrosting frost and ice attached on and around the cooler 111 at the time of cooling. Furthermore  a discharged water receiving dish 114 is provided below the radiant heater 113 so as to receive water resulting from defrosting and discharge the water outside the refrigerator. In addition  an evaporation dish 116 is provided at a downstream of the discharged water receiving dish 114 outside the refrigerator.
[0048]
The depth surface partition wall 110 includes: a discharge port 115 for directing cool air generated by the cooler 111 to the freezer compartment 106 using a cooling fan 112; and a suction port 117 for returning the cool air circulated in the freezer compartment 106 to the cooler 111.
[0049]
In addition  a storage case 126 for storing foods is disposed inside the freezer compartment 106. The storage case 126 is drawn together with a drawer.
[0050]
As shown in FIG. 3A  a gasket 121 is provided along the whole inner peripheral portion of the door 119 (this is true of the refrigerator compartment 104 and the vegetable compartment 105). The gasket 12 prevents leakage of the cool air inside the freezer compartment 106 and the vegetable compartment 105 by being closely in contact with the abutting member 123 made of metal and provided on the front surface of the partition body 122. Here  the partition body 122 is made of resin which is a member for vertically partitioning the main body into the vegetable compartment 105 and the freezer compartment 106.
[0051]
Furthermore  the partition body 122 includes a prevention part 124 formed in the proximity of the abutting member 123 (in the lower part in this embodiment). The prevention part 124 is a part of the partition body 122 and is for preventing the abutting member 123 from directly coming into contact with the inner spaces of the vegetable compartment 105 and the freezer compartment 106. The prevention part 124 prevents increase in the temperatures of the vegetable compartment 105 and the freezer compartment 106 due to heat conduction. In the prevention part for preventing heat penetration in this way  the prevention part 124 is a heat conduction prevention part for preventing heat conduction caused by abutting of material bodies that are solid bodies.
[0052]
In addition  a radiator pipe 131 is fixedly set up at a portion which is of the partition body 122 and is in contact with the rear surface of the abutting member 123. The radiator pipe 131 is a tube body for preventing dew condensation of the front part that is the abutting member 123 of the partition body 122. The radiator pipe 131 allows internal passage of a high-temperature coolant in the freezing cycle system (not shown). Accordingly  dew condensation is prevented by heating the abutting member 123 using heat exchange with the high-temperature coolant.
[0053]
As shown in FIG. 4 and FIG. 5  the prevention part 124 is provided below the abutting member 123 and along the whole width of the partition body 122. In addition  openings 128 are provided at both end portions in the width direction of the prevention part 124. The openings 128 have protrusive shapes protruding externally in the width direction  and are inserted into insertion holes 127 provided at portions corresponding to the both walls of the inner case 103. The front part of the partition body 122 is fixed to the main body 101 by inserting the openings 128 into the main body 101 in this way.
[0054]
As shown in FIG. 6  a heat insulation material 134 is disposed between inside the refrigerator and the radiator pipe 131 which is fixedly set up on the rear surface of the abutting member 123. The heat insulation material 134 prevents heat penetration from the radiator pipe 131 to the refrigerator via the partition body 122. Furthermore  a foam heat insulation material 130 is filled in the prevention part 124 provided below the abutting member 123. This increases the heat insulation efficiency by the prevention part 124  and prevents heat from directly penetrating the refrigerator from the abutting member 123.
[0055]
In addition  the partition body 122 includes an air hole 132 which connects the inner space and outside space of the prevention part 124  in addition to the openings 128. Thus  it is possible to increase the flowability of the foam heat insulation material 130 which is filled via the openings 128 located on the side surfaces of the partition body 122 and securely fill the foam heat insulation material 130 into the whole inner space of the prevention part 124  and thereby to secure the heat insulation property. The air hole 132 is provided toward the depth side of the refrigerator 100 when seen from the prevention part 124. The partition body 122 further includes a foam heat insulation material storage space 133 at the depth side of the refrigerator 100 when seen from the air hole 132  and thereby prevents the foam heat insulation material 130 from leaking toward the exterior sides of and the interior sides of the storage compartments.
[0056]
As shown in FIG. 7  the partition body 122 includes an upper partition board 135 and a lower partition board 136. In other words  the partition body 122 is formed by vertically combining the upper partition board 135 and the lower partition board 136. In addition  the prevention part 124 is also composed of the upper partition board 135 and the lower partition board 136. The partition body 122 is fixedly set up to include the heat insulation member 137 between the upper partition board 135 and the lower partition board 136 and thereby to prevent heat exchange between the storage compartments having mutually different temperature ranges.
[0057]
As shown in FIG. 8 and FIG. 9  the upper partition board 135 includes protrusion portions 140 for interfitting with recess portions 142 of the lower partition board 136 so as to define the positions of the upper and lower partition boards in the depth direction. Interfitting the protrusion portions 140 and the recess portions 142 secures the appearance quality of the refrigerator and prevents leakage of the foam heat insulation material. In addition  interfitting claw hook portions 141 provided on the upper partition board 135 and recess portions provided on the lower partition board 136 defines the positions of the upper and lower partition boards in the vertical direction  secures the appearance quality  and prevents leakage of the foam heat insulation material.
[0058]
Hereinafter  descriptions are given of operations and effects of the refrigerator configured as described above.
[0059]
First  a description is given of flow of cool air inside the freezer compartment 106. The cool air generated by the cooler 111 is forcibly blown from the discharge port 115 to each of the upper shelf  middle shelf  and lower shelf of the freezer compartment 106 by using the cooling fan 112 rotating with rotation of a motor. The cool air is blown into the storage case 126 and cools the foods stored therein. As shown by arrows  the air path is configured so that the cool air already cooled the foods is suctioned into the suction port 117 via a gap between the storage case 126 and the bottom wall of the inner case  and returns to the cooler 111.
[0060]
As described above  the cool air is heated by heat exchange with a comparatively high-temperature portion such as a wall surface when the cool air is circulated within the freezer compartment 106. The abutting member 123 heated by the radiator pipe 131 has a temperature higher than the temperature of the cool air. However  the prevention part 124 provided below the abutting member 123 prevents the abutting member 123 from directly coming into contact with the cool air. In this way  it is possible to prevent the cool air from being heated  and thereby to increase the cooling efficiency and  as a result  to reduce the amount of electric power consumption.
[0061]
In addition  preventing the cool air from being heated makes it possible to uniformly maintain the temperature distribution in the whole inner space of the freezer compartment 106 because the cool air constantly having a low temperature is circulated.
[0062]
Furthermore  with the prevention part 124 disposed below the abutting member 123  it is possible to reduce the contact between the gasket 121 and the cool air  and thereby to prevent heat exchange via the gasket 121. Furthermore  although the gasket 121 has a comparatively high temperature due to contact with the abutting member 123  the gasket 121 can further increase the heat exchange prevention effect because the contact between the gasket 121 and the cool air is reduced. In order to enhance this effect  it is desirable that the difference in the depth direction of the abutting member 123 and the front surface portion 122a of the partition body is within 5 mm. A large difference makes it difficult to close a gap between the gasket 121 and the front surface portion 122a of the partition body due to a lack of flexibility of the gasket 121  resulting in a reduction in the heat exchange prevention effect.
[0063]
The aforementioned advantage further makes it possible to prevent the abutting member 123 from being cooled by heat exchange with the abutting member 123 and the cool air and thereby to prevent the surface which is of the abutting member 123 and in contact with the outer space of the refrigerator from suffering dew condensation caused due to a significant difference in the temperatures of the inside and outside the refrigerator.
[0064]
Furthermore  filling a foam heat insulation material 130 having a high heat insulation efficiency into the prevention part 124 disposed below the abutting member 123 makes it possible to prevent heat exchange between the radiator pipe and the surface in contact with the cool air.
[0065]
The partition body 122 is configured by assembling the upper partition board 135 and the lower partition board 136 to sandwich the heat insulation member 137 between the upper and lower partition boards.
[0066]
The partition body 122 includes the prevention part 124 including  at the end portions  the openings 128 having protrusive peripheral portions. These protrusive openings 128 are inserted into the insertion holes 127 provided in the inner case 103 to be fixed therewith. The partition body 122 having the protrusive openings 128 facilitates filling of the foam heat insulation material 130 into the inner space of the prevention part 124 because these openings are protrusive from the inner case 103 to the outer case 102. For this reason  it is possible to increase the efficiency in filling the foam heat insulation material 130 into the prevention part 124. In addition  a gap of 1 mm or smaller formed between the protrusive openings 128 and the insertion holes 127 prevents the foam heat insulation material 130 infused via the openings 128 from leaking into the storage compartments of the refrigerator and thereby to prevent degradation of the internal quality of the refrigerator. Fixing these protrusive openings 128 in the insertion holes 127 defines the positional relationship between the partition body 122 and the inner case 103 in the depth direction  and thus further makes it possible to regulate the position of the partition body 122 in the depth direction.
[0067]
The foam heat insulation material 130 which is infused from the openings 128 provided at the both ends of the prevention part 124 has a property of being difficult to flow in a closed space. Thus  providing the air hole 132 for allowing release of the air inside the space at the center of the prevention part 124 makes it possible to securely fill the foam heat insulation material 130 into the prevention part 124. In this embodiment  the air hole 132 is provided only at the center point. However  such air holes may be provided plural points other than the center point depending on the flow state of the foam heat insulation material 130. The foam heat insulation material 130 which is filled into the prevention part 124 tends to leak to the outside via a gap present inside the prevention part 124. Thus  there is a high possibility that the foam heat insulation material 130 leaks also from the air hole 132. To prevent this  the foam heat insulation material storage space 133 for storing the leaked foam heat insulation material 130 is provided in a space toward the storage compartments when seen from the air hole. Actively causing the foam heat insulation material 130 infused excessively over the volume of the prevention part 124 to be infused into the foam heat insulation material storage space 133 prevents the foam heat insulation material 130 from leaking outside the refrigerator and into the storage compartments  and thereby prevents degradation of the appearance quality.
[0068]
Furthermore  filling the foam heat insulation material 130 also into a space between the outer case 102 and the inner case 103 makes it possible to reduce the number of man hours and the number of components.
[0069]
In addition  the prevention part 124 includes the upper partition board 135 including the protrusion portions 140 and claw hook portions 141 and the lower partition board 136 including the recess portions 142 and 143 such that the upper partition board 135 and the lower partition board 136 interfit with each other. According to the specifications  the prevention part 124 is made only of the upper partition board 135 and the lower partition board 136 in a way that gaps which occur between the components in the prevention part 124 when assembling the upper and lower partition boards are reduced  with an aim to keep the number of components and minimize the amount of material consumption. The protrusion portions 140 on the upper partition board and the recess portions 142 on the lower partition board interfit with each other prevent occurrence of gaps between these two components which may be caused when the upper and lower partition boards are pressed by the foaming pressure of the foam heat insulation material 130 filled inside the prevention part 124. The interfit portions further prevent a shape change of the front surface portion 122a of the partition body at the exterior side and forwarded toward the front side by the abutting member 123 made of metal  and thereby prevent degradation of the appearance quality due to the shape change. Furthermore  the claw hook portions 141 on the upper partition boards and the recess portions 143 on the lower partition board interfit with each other prevent occurrence of gaps between the upper and lower partition boards composing the prevention part 124 as described above  and thereby prevent a downward shape change due to the foaming pressure.
[0070]
Furthermore  the strength of the upper and lower partition boards composing the prevention part 124 is increased using components in order to prevent a shape change due to the foaming pressure. The components include a foaming jig which supports the partition body 122 composing the prevention part 124 from front and a movable jig which supports the same from below. In this way  it is possible to prevent the foam heat insulation material 130 from leaking outside due to the foaming pressure and prevent a shape change of the partition body 122 composing the prevention part 124  and thereby to secure the appearance quality.
[0071]
The prevention part 124 according to the present invention has the front surface portion 122a which is of the partition body and has a rectangular shape when seen from outside. This secures integrity with the abutting member 123  the peripheral components such as the inner case 103. This shape is employed with an aim to prevent degradation of the appearance quality in the case where the portions around the partition body are exposed when the door 119 is opened and to fully enjoy the heat exchange prevention effect after the door is closed. It is considered here that the front surface portion 122a of the partition body looks most beautifully when it is configured to have a rectangular shape. However  the front surface portion 122a may be configured to have another shape for better looking. For example  a curved shape or the like other than the rectangular shape may have more integrity as a whole depending on the shape and the like of the peripheral components.
[0072]
Here  the partition body 122 is configured by assembling the upper and lower partition boards by sandwiching the heat insulation member 137. However  it is also possible to obtain a heat insulation effect by filling a foam heat insulation material instead of using the heat insulation member 137.
[0073]
As described above  the refrigerator 100 according to this embodiment includes the main body 101 which is vertically partitioned into a plurality of storage compartments which receive supply of cool air by using the partition body 122. Each of the storage compartments is provided with an openable/closable door at the front surface portion. Each door is provided with a gasket 121 which becomes closely in contact with the abutting member 123 made of metal and disposed on the front surface which is of the partition body 122 and faces the door.
[0074]
The refrigerator 100 includes a structural element for heating the abutting member 123 and the gasket 121 and includes the prevention part 124 which prevents heat exchange between cool air inside the storage compartments and the abutting member 123. The prevention part 124 makes it possible to dispose heat insulation material between the abutting member 123 and the storage compartments. The heat insulation material having a low heat conduction efficiency reduces heat transfer to the contact surface at which the abutting member 123 having a high temperature increased by the radiator pipe 131 is in contact with the cool air. Therefore  it is possible to prevent increase in the temperature of the contact surface and to prevent heat exchange. In this way  it is possible to prevent the cool air from being heated  and thereby to increase the cooling efficiency and  as a result  to reduce the amount of electric power consumption.
[0075]
Here  the prevention part 124 is disposed above or below the abutting member 123 as shown in FIG. 3A. However  it is to be noted that the prevention parts 124 may be disposed above and below the abutting member 123 as shown in FIG. 3B instead.

[0076]
[Embodiment 2]
FIG. 10 is an enlarged cross-section view of a main part of a refrigerator according to Embodiment 2 of the present invention.
[0077]
It is to be noted that the same descriptions given of the same structural elements of Embodiment 1 and portions to which the same technical idea can be applied are not repeated here. These structural elements in Embodiment 1 can be arbitrarily combined with structural elements of this embodiment or applied to this embodiment unless any problem is produced. As shown in FIG. 10A  a gasket 121 is provided along the whole inner peripheral portion of a door 119 (this is true of a refrigerator compartment 104 and a vegetable compartment 105). Here  a partition body 122 is made of resin and is a member for vertically partitioning the vegetable compartment 105 and a freezer compartment 106. An abutting member 123 made of metal is provided on the front surface portion of the partition body 122. An abutting member 123 and a gasket 121 are closely in contact with each other to close the storage compartment.
[0078]
In addition  a radiator pipe 131 is fixedly set up on the rear portion of the abutting member 123.
[0079]
Furthermore  a prevention part 124 is included in the partition body 122 to be located below the abutting member 123. In this embodiment  the depth side of the prevention part 124 is in an open state  and thus the inner space of the prevention part 124 and the inner space of the partition body 122 are connected. A heat insulation member 137 is incorporated and fixed inside the integrated space composed of the two inner spaces.
[0080]
Hereinafter  descriptions are given of operations and effects of the refrigerator configured as described above. The same descriptions are not repeated for the same operations and effects as in Embodiment 1.
[0081]
Integrally forming the heat insulation member 137 which is disposed in the partition body 122 to reach the inner space of the prevention part 124 disposed below the abutting member 123 makes it possible to reduce the number of components and the number of man hours. Since there is no border between the prevention part 124 and the partition body 122  it is possible to prevent occurrence of a gap and thereby to prevent heat exchange between the upper and lower storage compartments having mutually different temperature ranges.
[0082]
In this embodiment  the heat insulation member 137 is incorporated. However  it is also possible to fill a foam heat insulation material into the inner space of the partition body 122 including the prevention part 124 instead of using the heat insulation member 137. At this time  the foam heat insulation material is filled into the inner space via holes provided in the inner case 103 and holes (not shown) provided in the partition body 122.
[0083]
As described above  in this embodiment  the inner space of the prevention part 124 and the inner space of the partition body 122 are integrated  and the heat insulation member 137 is incorporated into the integrated inner space or the foam heat insulation material is filled into the integrated inner space. Thus  in addition to the effects produced in Embodiment 1  this embodiment makes it possible to reduce the number of components and the number of man hours. Furthermore  since integrating the heat insulation component makes it possible to reduce the gap between the components  it is possible to prevent heat exchange between the upper and lower storage compartments and thereby to reduce the amount of electric power consumption.

[0084]
[Embodiment 3]
FIG. 11 is an enlarged cross-section view of a main part of a refrigerator according to Embodiment 3 of the present invention.
[0085]
It is to be noted that the same descriptions given of the same structural elements of any one of Embodiment 1 and Embodiment 2 and portions to which the same technical idea can be applied are not repeated here. These structural elements in any one of Embodiments 1 and 3 can be arbitrarily combined with structural elements of this embodiment or applied to this embodiment unless any problem is produced.
[0086]
As shown in FIG. 11  a refrigerator 100 includes a gasket 121 along the whole inner peripheral portion of a door 119 (this is true of a refrigerator compartment 104 and a vegetable compartment 105). The refrigerator 100 includes a heat insulation partition part 150 which partitions the vegetable compartment 105 and a freezer compartment 106). A heat insulation partition part 150 is integrally formed with an inner case 103. Storage compartments having mutually different temperature ranges are provided between the heat insulation partition part 150 and a door 119. In other words  a partition body 122 is provided which prevents direct communication of cool air between the storage compartments having mutually different temperature ranges. The partition body 122 includes an abutting member 123 which is made of metal and closely in contact with the front surface of the partition body 122.
[0087]
In addition  a radiator pipe 131 is fixedly set up on the rear surface of the abutting member 123 in order to prevent dew condensation on the outer surfaces of the storage compartments. This radiator pipe 131 used here is a high-temperature coolant pipe in a freezing cycle system (not shown)  and the heat of this radiator pipe 131 increases the temperature of the abutting member 123 up to a high temperature.
[0088]
Hereinafter  descriptions are given of operations and effects of the refrigerator configured as described above. The same descriptions are not repeated for the same operations and effects as in Embodiment 1 and Embodiment 2.
[0089]
Forming  inside the inner case 103  the heat insulation partition part 150 with a foam insulation material filled therein as a member for partitioning mainly the storage compartments having mutually different temperature range makes it possible to fill the foam heat insulation material without making any boarder between a main body 101 and the heat insulation partition part 150. This provides an excellent heat insulation effect  and particularly useful in the case where the temperature ranges of the storage compartments partitioned by the heat insulation partition part 150 are significantly different from each other. In addition  the heat insulation partition part 150 is integrally formed with the inner case 103 formed by vacuum forming.
[0090]
In addition  forming the partition body 122 only at the front portions of the storage compartments makes it possible to attach the prevention part 124 and the abutting member 123 having the radiator pipe 131 at the rear surface after the foaming in the main body 101  and thereby to increase the efficiency in the assembly operation.
[0091]
The partition body 122 only at the front portions of the storage compartments is fixed with the heat insulation partition part 150 using machine screws or the like. At this time  a gap may be generated between the components. Attaching a sealing member between the partition body 122 and the heat insulation partition part 150 makes it possible to prevent cool air from circulating via the gap.
[0092]
In this embodiment  the storage compartments having mutually different temperature ranges are partitioned by using the partition body 122 and the heat insulation partition part 150. Thus  it is possible to provide an effect of preventing heat exchange between the cool air inside the storage compartments and the abutting member 123 and an effect of enabling the heat insulation partition part 150 to provide a high heat insulation effect. Accordingly  it is possible to reduce the amount of electric power consumption.
[0093]
In each of Embodiment 1 to Embodiment 3  the prevention part 124 is located below the abutting member 123. However  the prevention part 124 may be located above the abutting member 123 or a plurality of prevention parts 124 may be located both above and below the abutting member 123.

[0094]
[Embodiment 4]
FIG. 12 is an enlarged cross-section view of a refrigerator according to Embodiment 4 of the present invention.
[0095]
FIG. 13 is a perspective view of the refrigerator according to Embodiment 4 of the present invention.
[0096]
It is to be noted that the same descriptions given of the same structural elements of any one of Embodiment 1 to Embodiment 3 and portions to which the same technical idea can be applied are not repeated here. These structural elements in any one of Embodiments 1 to 3 can be arbitrarily combined with structural elements of this embodiment or applied to this embodiment unless any problem is produced.
[0097]
As shown in FIG. 12 and FIG. 13  the partition body 122 includes an upper partition board 135 and a lower partition board 136  and further includes a heat insulation member 137.
[0098]
The upper partition board 135 includes a rib 162 for forming a first prevention part 160 and a second prevention part 161 which are closed spaces at attachment positions of an inner case 103. The first prevention parts 160 are provided on the both side surfaces and the rear surface of the partition body 122. The second prevention parts 161 are defined  by ribs 162  as closed spaces different from the first prevention parts 160. The third prevention parts 163 form closed spaces defined by recess portions of the inner case 103 and the partition body 122. The second prevention parts 161 and the third prevention parts 163 are provided on the both side surfaces and the rear surface of the partition body 122  as in the case of the first prevention part 160.
[0099]
The inner space of the partition body 122 and the inner space of the main body 101 are connected by a plurality of inner case holes 164 which are provided in the inner case 103 and correspond to a contact surface on which the partition body 122 and the inner case 103 are in contact with each other. Thus  a foam heat insulation material is infused and filled into the inner space of the partition body 122 via the inner case holes 164 when the foam heat insulation material is filled into the main body 101. These inner case holes 164 are provided on the both side surfaces and the rear surface of the partition body 122. A connection space 165 is a space obtained by forming a hole at a position on one of the side surfaces or the rear surface of the inner case 103. The side surfaces and the rear surface is the contact portion on which the partition body 122 and the inner case 103 are in contact with each other.
[0100]
A first prevention part 160  a second prevention part 161  and a third prevention part 163 are provided between the lower partition board 136 and the inner case 103  as in the case of the upper partition board 135. These prevention parts 160  161  and 163 among the prevention parts for preventing heat penetration are intended to prevent mainly heat transfer caused by gas movement.
[0101]
Hereinafter  descriptions are given of operations and effects of the refrigerator configured as described above. The same descriptions are not repeated for the same operations and effects as in any one of Embodiment 1 to Embodiment 3.
[0102]
The partition body 122 partitions the upper and lower storage compartments having mutually different temperature ranges in an insulated manner  and thereby maintains the temperature ranges inside the respective storage compartments. However  a slight gap between components is generated at the attachment positions of the partition body 122 and the inner case 103. Leakage of cool air between the upper and lower storage compartments via the gap makes it difficult for the partition body 122 to exert the heat insulation effect. Furthermore  depending on cases  such leakage of cool air may produce a quality problem such as dew condensation.
[0103]
In the present invention  the first prevention parts 160 in which no air convection occurs are provided between the attachment positions of the partition body 122 and the inner case 103. Thus  the present invention makes it possible to prevent cool air vertically passing through the partition body 122 and the inner case 103 via the gap therebetween and to prevent heat transfer therebetween. In addition  the second prevention parts 161 different from the first prevention parts 160 are additionally arranged closer to an outer case 102 than the first prevention parts 160 to create plural kinds of spaces for preventing communication of cool air. This makes it possible to increase the heat transfer prevention effect. The first prevention part 160 and the second prevention part 161 are defined by the ribs 162 of the upper partition board 135. Furthermore  the third prevention parts 163 defined  by the inner case 103 having recess portions  as a space between the partition body 122 and the inner case 103. This makes it possible to further prevent heat transfer. In this embodiment  the first prevention parts 160 and the second prevention parts 161 are provided in a double structure at both the upper side and the lower side of the partition body 122  and the third prevention parts 163 are further provided on the rear surface side of the partition body 122. In other words  each of the storage compartments is provided with the prevention parts in a triple structure. The triple-structure prevention parts securely prevent heat transfer.
[0104]
The connection space 165 is obtained by forming the inner case holes 164 at positions on the side surfaces and the rear surface of the inner case 103. The side surfaces and the rear surface are the contact portions on which the partition body 122 and the inner case 103 are in contact with each other. The connection space 165 makes it possible to increase the airtightness by filling the foam heat insulation material 130 into the inner case 103 via the inner case hole 164  and thereby to increase the energy saving effect.

[0105]
[Embodiment 5]
FIG. 14 is an enlarged cross-section view of a refrigerator according to Embodiment 5 of the present invention.
[0106]
It is to be noted that the same descriptions given of the same structural elements of any one of Embodiment 1 to Embodiment 3 and portions to which the same technical idea can be applied are not repeated here. These structural elements in any one of Embodiments 1 to 3 can be arbitrarily combined with structural elements of this embodiment or applied to this embodiment unless any problem is produced.
[0107]
As shown in FIG. 14  the partition body 122 is composed of an upper partition board 135 and a lower partition board 136  and a heat insulation member 137 therebetween. The upper partition board 135 includes a second prevention part 161 which is a heat transfer prevention part at an attachment position of the inner case 103. The second prevention part 161 is provided between the upper partition board 135 and the inner case 103. Inner case protrusion portions 166 are provided at attachment positions of the inner case 103 to which the partition board is attached so as to partially reduce the gap between the upper partition board 135. In addition  a fourth prevention part 167 having functions as a heat transfer prevention part and as a heat conduction prevention part is provided to the upper partition board 135 at a position toward the inside of the storage compartments. The inner case protrusion portions 166 are provided on the both side surfaces and the rear surface of the partition body 122  and each of which partitions a corresponding one of the fifth prevention parts 168 and a corresponding one of the six prevention parts 169. In addition  the fourth prevention parts 167 are closed in an almost airtight manner only by the partition body  and each of which includes a contact portion 167a which is in contact with the inner case 103.
[0108]
In addition  a second prevention part 161  a fourth prevention part 167  a fifth prevention part 168  a sixth prevention part 169  and an inner case protrusion part are provided between the lower partition board 136 and the inner case 103  as in the case of the upper partition board 135.
[0109]
Hereinafter  descriptions are given of operations and effects of the refrigerator configured as described above. The same descriptions are not repeated for the same operations and effects as in any one of Embodiment 1 to Embodiment 4.
[0110]
Providing the second prevention parts 161 in which no air convection occurs between the attachment positions of the partition body 122 and the inner case 103 makes it possible to prevent cool air passing through the gap and to prevent heat transfer. Providing protrusion portions at the attachment positions on the both side surfaces and the rear surface of the inner case 103 makes it possible to narrow the gap at the attachment positions and thereby to block flow of the cool air. The fourth prevention part 167 formed using the upper partition board 135 is a space which is completely independent from the second prevention part 161 defined by the contact portion between the partition body 122 and the inner case 103  and in which no air convection occurs because the fourth prevention part 167 is completely cut off from the storage compartment. Therefore  it is possible to increase the heat transfer prevention effect.
[0111]
The fourth prevention part 167 includes a contact portion 167a which is a surface in contact with the inner case 103 and is provided at a position closer to the storage compartment. Thus  it is possible to prevent cool air transfer because no air convection occurs inside the space even in the case where  for example  a depth displacement between compartments occurs when the shape of the inner case is changed due to urethane foam. In addition  it is also possible to prevent heat transfer because no cool air penetrates inside the fourth prevention part 167 even in the case where a vertical displacement between compartments occurs.
[0112]
Since the fifth prevention part 168 and the sixth prevention part 169 are partitioned by the protrusion portion 166  the protrusion portion 166 is pressed by the partition body 122 with a foaming pressure of the urethane foam generated when the main body was generated. Thus  it is possible to increase the airtightness of the fifth prevention part 168 and the sixth prevention part 169.

[0113]
[Embodiment 6]
FIG. 15 is an enlarged cross-section view of a main part of a refrigerator according to Embodiment 6 of the present invention.
[0114]
FIG. 16 is an exploded view of a main part of the refrigerator according to Embodiment 6 of the present invention.
[0115]
As shown in FIG. 15  a gasket 121 is provided along the whole inner peripheral portion of a door 119. The gasket 121 is closely in contact with the abutting member 123 provided on the front surface of the partition body 122 which partitions the refrigerator compartment 104 and the vegetable compartment 105.
[0116]
In addition  a radiator pipe 131 is fixedly set up for the abutting member 123 in order to prevent dew condensation on the outer surfaces of the storage compartments. This radiator pipe 131 used here is a high-temperature coolant pipe in a freezing cycle system (not shown)  and the heat of this radiator pipe 131 increases the temperature of the abutting member 123 up to a high temperature.
[0117]
Furthermore  the prevention part 124 located below the abutting member 123 includes an attachable prevention part 170 which is a member different from the partition body 122. The prevention part 124 is formed when the attachable prevention part 170 is fixedly attached to the partition body 122 by using machine screws or by claw hook interfit after a foam heat insulation material is filled into the main body 101.
[0118]
Hereinafter  descriptions are given of operations and effects of the refrigerator configured as described above. The same descriptions are not repeated for the same operations and effects as in Embodiment 1.
[0119]
Since the prevention part 124 provided below the abutting member 123 includes the attachable prevention part 170 which is a member different from the partition body 122  it is possible to easily determine whether a heat conduction prevention structure is present or absent based on the presence or absence of the member  for each of a plurality of machines which are similar in the outer shapes and compartment layouts but different in the temperature ranges and prices. Thus  it is possible to utilize the same casing for various kinds of needs  and to reduce the number of foaming jigs by sharing some foaming jigs.
[0120]
Furthermore  with the heat insulation member 171 fixedly adhered inside the prevention part 124 including the attachable prevention part 170  it is possible to further increase the effect of preventing heat penetration from the abutting member 123.
[0121]
The temperature range of the vegetable compartment 105 in this embodiment can be lowered to a range including minus degrees Celsius by changing the temperature setting. Thus  it is possible to prevent heat penetration more effectively by providing the attachable prevention part 170 at a position closer to the vegetable compartment 105 having the lower temperature range among the upper and lower storage compartments which sandwich the partition body 122. In addition  fixedly attaching the attachable prevention part 170 at the lower portion of the partition body 122 makes it possible to position the holes for machine screws  claw hooks  or the like which can be seen when the attachable prevention part 170 is detached  at positions at the lower surface side of the partition body 122 which are difficult to see from the normal eye positions. In this case  it is also possible to secure the appearance quality of a machine from which the attachable prevention part 170 is detached.

[0122]
[Embodiment 7]
FIG. 17 is an enlarged cross-section view of a main part of a refrigerator according to Embodiment 7 of the present invention.
[0123]
As shown in the diagram  as in Embodiment 6  a prevention part 124 includes a lower attachable prevention part 170a which is a member different from a partition body 122 at the lower side of an abutting member 123  and further includes an upper attachable prevention part 170b which is a member different from the partition body 122 at the upper side of the abutting member 123. The respective attachable prevention parts 170a and 170b are fixedly attached to the partition body 122 by using machine screws and by claw hook interfit after a foam heat insulation material is filled into the main body 101. In addition  a heat insulation member 171a and a heat insulation member 171b may be attached each of the upper and lower attachable prevention parts 170a and 170b.
[0124]
Hereinafter  descriptions are given of operations and effects of the refrigerator configured as described above. The same descriptions are not repeated for the same operations and effects as in Embodiment 6.
[0125]
The attachable prevention parts are provided at both the upper and lower sides of the abutting member 123. This makes it possible to further increase the effect of preventing heat penetration from the abutting member 123.
