, Description:[001] TECHNICAL FIELD

[002] Present disclosure generally relates to the field of automobiles. Particularly, but not exclusively, the present disclosure relates to an air vent for an air conditioning system of a vehicle. Further, embodiments of the present disclosure disclose the air vent, which can be toggled between focused and diffused air flow modes.

[003] BACKGROUND OF THE DISCLOSURE

A heating ventilating and air conditioning (HVAC) unit or simply referred to as air conditioning unit, is employed in majority of vehicles ranging from passenger vehicles to commercial vehicles. HVAC in general provides comfort to passengers in different climatic conditions. In the HVAC unit, air may be drawn either from inside the cabin of the vehicle or from atmosphere, based on the requirement. The air may be conditioned [i.e. cooled or heated] by the HVAC unit as per need of the passengers or to achieve ambient temperature conditions within the cabin. The air so conditioned, may then be delivered to the cabin of the vehicle through one or more air vents provided in the cabin.

Generally, the HVAC unit may consist of a blower unit, one or more heat exchangers, and one or more air vents. The fresh air or re-circulated air may be sucked through an intake assembly of the blower unit. The blower unit may then force the air to move forward and gives it velocity and momentum to move towards the heat exchanger coils. The air which is passing over or through the heat exchanger coils, contacts with it to dissipate or absorb heat. This conditioned air may be passed through the one or more air ducts to blow and circulate the air to the vehicle cabin through the air vents.

Conventional air vents include a number of geometrical shapes such as circular, rectangular, and square to supply air from the air conditioning system into the cabin of the vehicle, and also to add aesthetic appeal to the interior of the vehicle cabin. However, the conventional air vents direct air unscientifically, that may lead to reduced cooling efficiency, poor directivity of air and so forth. Further, the conventional air vents are not flexible nor designed to adjust the air flow based on the requirement of an occupant inside the vehicle. In case of hot soak cabin conditions, different climatic conditions and based on comfort level of the occupant, the occupant may require air flow directly on to the body (i.e. focussed air flow), for effective cooling and. Further, in case of ambient temperature conditions of the cabin, the occupant may require unfocussed (i.e. diffused) air flow. The conventional air ducts fail to cater different air flows (i.e. focussed and diffused air flow), based on requirement of the occupant.

Considering the above, and with the advent of technology, air vents which are configured to toggle between the focused air flow and the diffused air flow have been developed. However, the conventional air vents include multiple vanes for directing air based on the requirement of the occupant. Using multiple vanes would increase the number of movable parts in the air vent, which ultimately increases weight and, thus cost of the air vent. Moreover, increased number of parts may lead to complex construction and mechanism which is not desirable. In addition, more number of moving parts in the air vents, results in noise generation during operation, causing discomfort to the occupant.

[004] The present disclosure is directed to overcome one or more limitations stated above or other such limitations associated with the prior art.

[028] The figures depict embodiments of the disclosure for purposes of illustration only. One skilled in the art will readily recognize from the following description that alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles of the disclosure described herein.

[029] DETAILED DESCRIPTION

[030] While the embodiments in the disclosure are subject to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the figures and will be described below. It should be understood, however, that it is not intended to limit the disclosure to the particular forms disclosed, but on the contrary, the disclosure is to cover all modifications, equivalents, and alternative falling within the scope of the disclosure.

[031] It is to be noted that a person skilled in the art would be motivated from the present disclosure and modify various features of the mechanism and system, without departing from the scope of the disclosure. Therefore, such modifications are considered to be part of the disclosure. Accordingly, the drawings show only those specific details that are pertinent to understand the embodiments of the present disclosure, so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skilled in the art having benefit of the description herein. Also, the air vent of the present disclosure may be employed in variety of air conditioning systems apart from what is being used in vehicles. However, the air conditioning system and the vehicle is not illustrated in the drawings of the disclosure for the purpose of simplicity.

[032] The terms “comprises”, “comprising”, or any other variations thereof used in the disclosure, are intended to cover a non-exclusive inclusion, such that a mechanism or system that comprises a list of components does not include only those components but may include other components not expressly listed or inherent to such system, method, or assembly, or device. In other words, one or more elements in a device proceeded by “comprises… a” does not, without more constraints, preclude the existence of other elements or additional elements in the device.

[033] Embodiments of the present disclosure disclose an air vent for an air conditioning system of a vehicle. Conventional air vents direct air unscientifically, that may lead to problems like reduced cooling efficiency, poor directivity of air and the like, leading to discomfort of the occupant. Further, the conventional air vents are not flexible to adjust the air flow based on the requirement of an occupant inside the vehicle. In case of hot soak cabin conditions, different climatic conditions and based on comfort level of the occupant, the occupant may require air flow on to the body (i.e. focused air flow) for effective cooling and, in case of ambient temperature conditions of the cabin, the occupant may require unfocussed (i.e. diffused) air flow. The conventional air ducts fail to cater different air flows (i.e. focused and diffused air flow), based on requirement of the occupant. However, some of the conventional air vents include multiple vanes for directing the air based on the requirement of the occupant. Using multiple vanes would increase the number of movable parts in the air vent, which increases weight and, thus cost of the air vent. Moreover, increased number of parts leads to complex construction and mechanism, which is not desirable. In addition, as the conventional air vents include a number of moving parts, it results in noise generation during operation, causing discomfort to the occupant.

[034] Accordingly, the present disclosure discloses an air vent for an air conditioning system. The air vent may be configured to deliver focused air flow, diffused air flow and simultaneously both focused air flow and diffused air flow, with minimum moving parts. Further, the air vent provides effortless toggling from one mode of air flow to the another.

[035] The air vent of the present disclosure may include a housing, which may be configured with at least one guide way on an inner circumference. Further, the air vent may include an air channelizing member, which may be movably disposed within the housing. The air channelizing member may be defined with a first air passage and may be configured with a protrusion at one end. Further, the air channelizing member may linearly displace between a first position and a second position within the housing, to change the mode of air flow.

[036] In an operational embodiment, at the first position of the air channelizing member, the protrusion configured in the air channelizing member may engage with an inner wall of the housing. This engagement allows flow of air through the first air passage defined in the air channelizing member and, thus provides focused air flow. Further, when the air channelizing member is displaced from the first position to the second position, the protrusion may disengage from the inner wall of the housing. This disengagement of the protrusion from the inner wall may define one or more second air passages, between an inner circumference of the housing and an outer circumference of the air channelizing member. Air may flow through the one or more second passages to provide diffused air flow.

[037] The following paragraphs describe the present disclosure with reference to Figures. 1 to 6. In the figures, the same element or elements which have similar functions are indicated by the same reference signs.

[038] Figure. 1 illustrates a perspective view of an air vent (101) for an air conditioning system of the vehicle. The air vent (101) may be configured to deliver focused air flow, diffused air flow and both focused and diffused air flow based on the requirement, with minimum moving parts. In an embodiment, the focused air flow may be construed as velocity of air flow being high and the air flow being directed to a specific portion of an occupant. The focused air flow may cater effective or instant cooling to the occupant or a portion of the cabin. In another embodiment, the diffused air flow may be construed as velocity of the air flow being relatively low, but the air flow being directed to a wider portion or area of the occupant or cabin of the vehicle. The diffused air flow may cater gradual cooling to the occupant.

[039] As seen in Figure. 1, the air vent (101) may include a housing (102). The housing (102) may include a first section (108) and a second section (109), which may be separated by an intersection portion (116). As an example, the intersection portion (116) may be inferred to as a point of contact of end portions of the first section (108) and the second section (109). In an embodiment, the first section (108) may be configured with a convergent configuration and the second section (109) may be configured with a divergent configuration, along a length of the housing (102). In other words, diameter of the first section (108) constantly decreases towards the intersection portion (116) and diameter of the second section (109) constantly increases away from the intersection portion (116). That is, the first section (108) and the second section (109) of the housing (102) may converge at the intersection portion (116). As an example, the housing (102) may be a unitary structure i.e. a single structure without any joints. In an embodiment, the first section (108) of the housing (102) may be coupled to an air duct (115) of the air conditioning system, in order to direct air from the air conditioning unit.

[040] Now referring to Figure. 2, which illustrates a sectional view of the air vent (101). As seen in Figure. 2, the housing (102) may be configured with at least one guide way (103). The at least one guide way (103) may include a rail (117), which may be supported by a support structure (118), extending away from an inner circumference of the housing (102) towards a central axis of the air vent (100). In an embodiment, the rail member (117) may be defined with a slot (not shown in Figures), which may extend through a certain length of the rail (117). In an illustrated embodiment, the housing (102) is configured with two guide ways and the same should not be construed as a limitation, as a plurality of guide ways may be configured in the housing (102), based on the requirement. As apparent from Figure. 2, the air vent (101) may further include an air channelizing member (104), which may be movably disposed within the housing (102). The air channelizing member (104) may include a body portion, which may define a first air passage (105). In the illustrated embodiment, the air channelizing member (104) is defined with a cylindrical configuration, which may not be construed as a limitation as the air channelizing member (104) may be defined in any geometrical configuration, based on the requirement. Further, the air channelizing member (104) may be configured with a protrusion (106) at one end and may include a ball joint (112) at another end (i.e. at an end opposite to the end at which the protrusion (106) is configured). In an embodiment, the protrusion (106) configured at one end of the air channelizing member (104) may extend around a circumference of the air channelizing member (104) and, may be defined with a shape corresponding to shape of the housing (102). In an embodiment, the ball joint (112) may be configured to be operated in any desired direction, to alter a direction of air flow exiting from the air vent (101), based on the requirement of the occupant. As apparent from Figure. 2 the air channelizing member (104) may further include a plurality of prongs (111), which may be defined on an outer surface of the air channelizing member (104). The plurality of prongs (111) may facilitate in movably disposing the air channelizing member (104) within the housing (102).

[041] In an embodiment, the air channelizing member (104) may linearly slide and displace between a first position and a second position within the housing (102). As seen in Figure. 2, the air channelizing member (104) may be disposed within the housing (102), such that the plurality of prongs (111) defined on the outer surface of the air channelizing member (104) may reside within the slot (not shown in figures) in the rail member (117) of the at least one guide way (103). As an example, the plurality of prongs (111) may form an interference fit with the slot and, thus may guide the air channelizing member (104), during linear displacement between the first position and the second position, to change the mode of air flow.

[042] In an embodiment, as apparent from Figure. 2, the air duct (115) may include stepped portion, which includes at least one connecting member (120). The stepped portion of the air duct (115) may receive a portion of the first section (108) of the housing (102). The portion of the first section (108) engages with the connecting member (120) and, thus the air duct (115) and the housing (102) may be connected for directing the air from the air conditioning unit.

[043] In an operational embodiment, as seen in Figure. 2 the air channelizing member (104) is at the first position. At the first position, the protrusion (106) of the air channelizing member (104) may engage with an inner wall of the housing (102). This engagement of the protrusion (106) with the inner wall of the housing (102), allows air flow only through the first air passage (105) defined in the air channelizing member (104). In an embodiment, as the first air passage (105) includes a substantially smaller area, compared to the area of the housing (102), velocity of the air flow increases and thus, provides focused air flow, which facilitates in catering effective cooling.

[044] Now turning to Figure. 3, which illustrates a sectional view of the air vent (101), with the air channelizing member (104), positioned at a second position. In an embodiment, the occupant may operate (thus, push) the air channelizing member (104) for linearly displacing the air channelizing member (104) from the first position (as seen in Figure. 2) to the second position, to change the mode of air flow. As an example, the occupant may grip the ball joint (112) configured at an end of the air channelizing member (104) to linearly displace the air channelizing member (104) from the first position to the second position and vice-versa. As apparent from Figure. 3, at the second position, the protrusion (106) of the air channelizing member (104) may disengage from the inner wall of the housing (102). In other words, the convergent configuration of the first section (108) of the housing (102), may facilitate in disengaging the protrusion (106) of the air channelizing member (104) from the inner surface of the housing (102), as the air channelizing member (104) from the first position to the second position. This disengagement of the protrusion (106) from the inner wall of the housing (102) may define one or more second air passages (107) within the housing (102). In an embodiment, the one or more second air passages (107) may be formed between an inner circumference of the housing (102) and an outer circumference of the air channelizing member (104), and may extend along an inner circumference of the housing (102). Air from the air conditioning unit may flow through one or more second air passages (107) and may be diverted by the divergent configuration of the second section (109) of the housing (102). In an embodiment, as the one or more second air passages (107) includes a substantially larger area, velocity of the air flow is relatively low and, thus provides diffused air flow.

[045] In an embodiment, at the second position of the air channelizing member (104), the air may flow through both the first air passage (105) defined in the air channelizing member (104) for providing focused air flow, and through the one or more second air passages (107) defined between the inner circumference of the housing (102) and the outer circumference of the air channelizing member (104) for providing diffused air flow. Thus, the air vent (101) may provide both focused air flow and diffused air flow, simultaneously at the second position of the air channelizing member (104).

[046] Referring to Figure. 4, which illustrates a sectional view of the air vent (101), in accordance to another embodiment of the present disclosure. The air vent (101) may include a housing (102), which may be defined in a cylindrical configuration, and may be configured with a divergent configuration. That is, diameter of the housing (102) may increase continuously along the length of the housing (102). The housing (102) may be connected to an air duct (115) of the air conditioning system. In an embodiment, the housing (102) may be configured with at least one guide way (103). The at least one guide way (103) may extend from an inner circumference of the housing (102). As apparent from Figure. 4, the air vent (101) may include an air channelizing member (104), which may be movably disposed within a housing (102). The air channelizing member (104) may include but not limiting to a cylindrical body, which may be defined with a first air passage (105). In an embodiment, the air channelizing member (104) may be defined with a plurality of grooves [not shown in Figures] on an outer circumference, which may be configured to engage with the at least one guide way (103) to form, but not limiting to an interference fit. This engagement of the air channelizing member (104) and the at least one guide way (103) may facilitate in displacement of the air channelizing member (104) between the first position and the second position within the housing (102). Further, the air channelizing member (104) may be configured with a protrusion (106) at one end, which may be configured to contact at least a portion of the inner wall of the housing (102). In an embodiment, the air vent (101) may include an inner barrel (119), which may be adapted to be operated for changing the direction of flow of air during diffuse flow, based on the requirement.

In an embodiment, as seen in Figure. 4, the air channelizing member (104) may be configured with a regulating plate (114) at one end. The regulating plate (114) mat be pivotally connected to the end of the air channelizing member (104). The regulating plate (114) may be operated between an open position to a closed position to allow, interrupt and regulate the flow of air through the first air passage (105) in the air channelizing member (104).

[047] In an operational embodiment and referring to Figure. 4, the air channelizing member (104) is at the first position. At the first position, the air channelizing member (104) may engage with an opening of the air duct (115) of the air conditioning system. In an embodiment, at the first position, the protrusion (106) may engage at least a portion of the inner wall of the housing (102). This engagement of air channelizing member (104) with the opening of the air duct (115), may allow air flow only through the first air passage (105) defined in the air channelizing member (104). In an embodiment, as the first air passage (105) includes a substantially smaller area, compared to the area of the housing (102), velocity of the air flow increases and thus, provides focused air flow, which helps in faster cooling.

[048] In an embodiment, the regulating plate (114) configured at one end of the air channelizing member (104) may be operated between the open position to the closed position to control or regulate the amount of air flow, based on the requirement of the commuter. In another embodiment, the regulating plate (114) may be operated to the closed position [as seen in Figure. 6] to interrupt the air flow, through the first air passage (105).

[049] Turning now to Figure. 5, which illustrates a sectional view of the air vent (101) depicting the air channelizing member (104) at the second position. In an embodiment, the user of the vehicle may operate the air channelizing member (104) from the first position to the second position to change the mode of air flow. In other words, the commuter may pull the air channelizing member (104), to displace from the first position to the second position. As seen in Figure. 5, the air channelizing member (104) is positioned at a second position. At the second position, the air channelizing member (104) may be positioned away from the opening of the air duct (115), and thus defining one or more second air passages (107) along an inner wall of the housing (102). That is, the one or more second air passages (107) may be defined between an inner circumference of the housing (102) and the outer circumference of the air channelizing member (104) to allow air to flow for providing diffused air flow. Further, the divergent configuration of the housing (102) may facilitate in diverting the air flow and, thus aids in providing effective diffused air flow.

[050] In an embodiment, at the second position of the air channelizing member (104) within the housing (102), the air may flow through the first passage defined in the air channelizing member (104) for providing focused air flow, and through the one or more second air passages (107) defined between the inner circumference of the housing (102) and the outer circumference of the air channelizing member (104) for providing diffused air flow. Thus, the air vent (101) of the present disclosure may provide both focused air flow and diffused air flow, simultaneously when the air channelizing member (104) is at the second position within the housing (102).

[051] In an embodiment, the air vent (101) of the present disclosure includes minimum moving parts and hence may provide hassle free cooling to the occupant. Further, the air vent (101) may be effortlessly operated by the commuter to switch between the focused air flow and the diffused air flow, and vice-versa.

[052] It is to be understood that a person of ordinary skill in the art may develop an air vent of similar configuration without deviating from the scope of the present disclosure. Such modifications and variations may be made without departing from the scope of the present invention. Therefore, it is intended that the present disclosure covers such modifications and variations provided they come within the ambit of the appended claims and their equivalents.

However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances, where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.” While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
