Specification

DESC:FIELD OF INVENTION
[0001] The present invention relates, in general, to stoves or cooking appliances. More particularly, the present disclosure relates to electrically ignited cooking appliances, such as hobs or cooktop assemblies.

BACKGROUND
[0002] A cooking appliance is known to include ignitors, such as piezoelectric type igniters, manual type igniters, or the like ignitors. In piezoelectric-type igniters, an ignition is produced by way of an electric charge that accumulates in a material in response to a mechanical deformation of the material. In manual type igniters, external tools like matchsticks or lighters are required to produce ignition. Such ignitors are either prone to early wear and/or make the ignition process cumbersome and time-consuming.

The power circuit system includes a power source and at least one transformer. The transformer is configured to convert a first power signal from the power source into a second power signal. The power circuit system includes at least one switch. The switch is configured to be actuated by the actuator to shift an electrical connection between the power source and the transformer between a closed state and an open state. In the closed state, the transformer is configured to receive the first power signal for conversion into the second power signal. The power circuit system includes a spark generator positioned in proximity to the burner. The spark generator is configured to receive the second power signal from the transformer to generate a spark to cause an ignition of a gas released from the burner.
[0004] According to another aspect of the present disclosure, a cooking appliance is described. The cooking appliance includes at least one burner and a valve fluidly coupled between the burner and a gas source. The cooking appliance further includes at least one actuator configured to move the valve to a first condition and a second condition. In the first condition, the valve is configured to regulate and provide a supply of a gas from the gas source to the one burner. In the second condition, the valve is configured to shut off the gas supply from the gas source to the one burner. The cooking appliance includes a power circuit system. The power circuit system includes a power source and at least one transformer. The transformer is configured to convert a first power signal from the power source into a second power signal. The power circuit system includes at least one switch. The switch is configured to be actuated by the one actuator to shift an electrical connection between the power source and the one transformer between a closed state and an open state. In the closed state, the one transformer is configured to receive the first power signal for conversion into the second power signal. The power circuit system includes a spark generator positioned in proximity to one burner. The spark generator is configured to receive the second power signal from the transformer to generate a spark to cause an ignition of a gas released from the one burner.

DETAILED DESCRIPTION
[0011] Reference will now be made in detail to specific embodiments or features, examples of which are illustrated in the accompanying drawings. Generally, corresponding reference numbers may be used throughout the drawings to refer to the same or corresponding parts could refer to one or more comparable components used in the same and/or different depicted embodiments. It should also be noted that the description provided below for an element 10 or 20 may be equally applicable to the element 10a, 10b, 10c, 10d or 20a, 20b, 20c, 20d, respectively, without any limitations.
[0012] Referring to FIG. 1, an exemplary cooking appliance 100 is shown and described. The cooking appliance 100 may be used, e.g., by one or more personnel or a human (user), to produce a flame (not shown) and generate heat so as to cook food or any item by using heat accompanying the flame. The cooking appliance 100 may include a burner 112 to produce the flame via the burner 112. In some embodiments, the cooking appliance 100 may include at least one actuator 108 to control the production of the flame and, thus, heat generation. Terms such as ‘cook’ or ‘cooking’, and similar such terms, as used in the present disclosure, may correspond to or include a way of preparing (e.g., mixing, combining, blending, etc., one or more food articles with each other) by use of the heat from the flame. Terms such as ‘heat’ or ‘heating’, as used in the present disclosure, may include, but are not limited to, boiling, baking, roasting, and grilling, e.g., of one or more food articles (that may be placed inside a vessel or a container) and which may be brought into contact with the flame for cooking. The heat from the flame could be used for other purposes as well, and the above discussion is exemplary.
[0013] The cooking appliance 100 may include various components and/or assemblies that may cooperate to perform the cooking. It is to be understood that the term “cooking appliance” is to be interpreted broadly as including not only self-contained units that are mounted in or onto a countertop or a tabletop surface, but also appliances that form part of larger cooking appliances, such as hobs, cooktops, commercial cooking units, stoves, cooking units that may be integrated with other systems for the performance of other functions, etc. For example, as shown in FIG. 1, the cooking appliance 100 may include a body B having a surface 102, at least one slot 104, and at least one burner 112 mounted in the one slot 104. The surface 102 may be made of a heat-resistant material, which may be metallic or ceramic, to withstand high temperatures generated during cooking.
[0014] In some embodiments, the slot 104 may be a cut-out extending through the surface 102 of the cooking appliance 100. The slot 104 may adopt various shapes that may include, but are not limited to, a circular, a rectangular, a triangular, and others as required. The burner 112 may be positioned within the slot 104, e.g., such that their longitudinal axes align and overlap. In some embodiments, the burner 112 may be positioned in the slot 104 by using one or more mounting means including, but not limited to, fasteners, clamps, or brackets that hold the burner 112 in place. The mounting means may allow an easy removal of the burner 112 during cleaning or maintenance of the cooking appliance 100.
[0015] In an example, the cooking appliance 100 may include four slots 104a, 104b, 104c, and 104d to accommodate four burners 112a, 112b, 112c, and 112d, therein. For example, the burners 112a, 112b, 112c, 112d, may be positioned within the corresponding slots 104a, 104b, 104c, 104d. In some embodiments, the cooking appliance 100 may include four actuators 108a, 108b, 108c, and 108d, located partly outward from the body B. Each actuator 108 of the four actuators 108a, 108b, 108c, 108d, may be operatively connected to each burner 112 of the four burners 112a, 112b, 112c, 112d. For example, the user may actuate any one of the actuators 108a, 108b, 108c, or 108d, to control the production of the flame from the corresponding burner 112a, 112b, 112c, or 112d (actuation of the actuator 108 is discussed in later sections).
[0016] In some embodiments, the cooking appliance 100 may receive a supply of gas (and/or gas/fuel mixture), such as a liquified petroleum gas (LPG), from a gas source S. The cooking appliance 100 may include a manifold 116 coupled (e.g., fluidly coupled) to the gas source S (via a fuel injector nozzle 136) to provide a passage to the gas from the gas source S to the burner 112. For example, upon actuating the actuator 108, the gas, from the gas source S, may travel to the burner 112 via the manifold 116 to be ignited at the burner 112. In some embodiments, the manifold 116 may include a manifold body 120, a first passage 124 between the fuel injector nozzle 136 and the manifold body 120. In some embodiments, the manifold 116 may include a pipeline 132 fluidly connected to the burner 112. In an example, the manifold 116 may include four pipelines 132a, 132b, 132c, 132d, and each pipeline 132a, 132b, 132c, 132d may be fluidly connected to the corresponding burner 112a, 112b, 112c, 112d. In such configuration, the manifold 116 may receive the gas (from the gas source S) into the manifold body 120 via the first passage 124 and provide passage to the received gas to the burner 112a, 112b, 112c, 112d upon actuation of the corresponding actuator 108a, 108b, 108c, 108d.
[0017] In some embodiments, the cooking appliance 100 may include a valve 128 fluidly coupled between the burner 112 and the gas source S. For example, the valve 128 may include an inlet 129 fluidly coupled via the manifold 116 (thus with the gas source S) and an outlet 130 may be fluidly coupled with the burner via the pipeline 132. In some embodiments, the cooking appliance 100 may include four valves 128a, 128b 128c, 128d, and each valve 128a, 128b 128c, 128d may be associated with the corresponding actuator 108a, 108b, 108c, 108d. In some embodiments, the manifold body 120 may be fluidly coupled with the four valves 128a, 128b, 128c, and 128d. In some embodiments, each valve 128 of the four valves 128a, 128b, 128c, 128d may be fluidly coupled to the corresponding burner 112 of the four burners 112a, 112b, 112c, 112d. For example, each valve 128a, 128b, 128c, 128d is fluidly coupled with each corresponding burner 112a, 112b, 112c, 112d via respective pipelines 132a, 132b, 132c, 132d. In some embodiments, each actuator 108a, 108b, 108c, 108d may be actuated and configured to move the corresponding valve 128a, 128b, 128c, 128d, to a first condition and to a second condition. For example, each actuator 108a, 108b, 108c, 108d may be configured to move the corresponding valve 128a, 128b, 128c, and 128d to the first condition to regulate and provide the supply of the gas from the gas source to the corresponding burner 112a, 112b, 112c, 112d. Further, each actuator 108a, 108b, 108c, 108d may be configured to move the corresponding valve 128a, 128b, 128c, 128d to the second condition to shut off the supply of the gas from the gas source S to the corresponding burner 112a, 112b, 112c, 112d. The first condition of each of the valves 128a, 128b, 128c, and 128d may be an open condition, permitting gas to flow from the gas source S from the corresponding inlet 129 to the corresponding outlet 130. The second condition of each of the valves 128a, 128b, 128c, and 128d may be a closed condition, restricting the gas from flowing between the corresponding inlet 129 and the corresponding outlet 130. In some embodiments, the valve 128 may be based on one or more of a solenoid valve, a ball valve, or any other type of valve, capable of regulating the supply of the gas from the gas source S to the burner 112. In some embodiments, the actuator 108 may be a device that includes at least one of or combination of a mechanical, an electrical, or an electronic device such as knobs, pushbuttons, switches, cams, gears, levers, solenoids, etc.
[0018] It should be noted that the cooking appliance 100 is not limited to only four burners 112a, 112b, 112c, 112d, as shown in FIG. 1, and may include any number of burners 112 (less or greater than four), each with the corresponding pipeline 134, valve 128, and the actuator 108, all fluidly coupled with the manifold 116 to regulate the supply of the gas to each burner 112.
[0019] Referring to FIGS. 2 and 3, the power circuit system 140 of the cooking appliance 100 is described. The power circuit system 140 may include a power source 144, at least one transformer 148 (e.g., one transformer 148 for one burner 112), and at least one spark generator 152 (e.g., one spark generator 152 for one burner 112). The transformer 148 may include a primary terminal T1 (as shown in FIG. 3) electrically connected with the power source 144 and a secondary terminal T2 (as shown in FIG. 3) electrically connected with the spark generator 152. In some embodiments, the power circuit system 140 may include four transformers 148a, 148b, 148c, 148d, and each transformer 148a, 148b, 148c, 148d may include corresponding primary terminal T1 and corresponding secondary terminal T2. Each transformer 148a, 148b, 148c, and 148d may be electrically connected to the power source 140 at their corresponding primary terminal T1. Further, each transformer 148a, 148b, 148c, 148d may be electrically connected to the corresponding spark generator 152a, 152b, 152c, and 152d, at their corresponding secondary terminal T2.
[0020] In some embodiments, each spark generator 152a, 152b, 152c, 152d may be positioned in proximity to the corresponding burner 112a, 112b, 112c, and 112d of the cooking appliance 100. For example, each spark generator 152a, 152b, 152c, and 152d may be positioned at a predetermined distance from the corresponding burner 112a, 112b, 112c, and 112d. The predetermined distance may be enough to ignite the gas being released from the burners 112a, 112b, 112c, and 112d via the spark generated by the corresponding spark generators 152a, 152b, 152c, and 152d. In some embodiments, the spark generator 152 may include but is not limited to, a spark plug, an electronic igniter, or any other suitable type of spark generation device. In some embodiment, the power circuit system 140 may include a resistor (not shown) electrically connected between the secondary terminal T2 and the spark generator 152. The resistor may be configured to regulate the power supply to the spark generator 152.
[0021] In some embodiments, the power circuit system 140 may include a switch 156a, 156b, 156c, 156d respectively, provided between the power source 144 and each transformer 148a, 148b, 148c, 148d. The switch 156a, 156b, 156c, 156d may configure to shift (or toggle) an electrical connection between the power source 144 and the corresponding transformer 148a, 148b, 148c, 148d between a closed state and an open state. In some embodiments, each actuator 108a, 108b, 108c, 108d may be operatively connected to each corresponding switch 156a, 156b, 156c, 156d. For example, at least one actuator 108a, 108b, 108c, 108d may be engaged and configured to trigger the corresponding switch 156a, 156b, 156c, 156d to alternate between the open and closed states. Upon engaging at least one actuator 108a, 108b, 108c, 108d, the electrical connection may switch from the open state to the closed state. In the closed state, the power source 144 may be configured to supply a power signal to the corresponding transformer 148a, 148b, 148c, 148d. In some embodiments, the switch 156 may include but is not limited to, a microswitch, a reed switch, or any other suitable type of switch capable to shift the electrical connection between the closed and open states.
[0022] In some embodiments, the cooking appliance 100 may include a plunger mechanism 160 provided between each actuator 108a, 108b, 108c, 108d and each corresponding switch 156a, 156b, 156c, 156d. In some embodiment, the actuator 108 may be configured to provide an engagement between the plunger mechanism 160 and the switch 156 to shift the electrical connection between the closed state and the open state. In some embodiments, the plunder mechanism 160 may include a plunger-shaped element and a spring (not shown). For instance, when the actuator 108 may be actuated (e.g., pressed or moved) by the user, the spring may get compressed, causing the plunger-shaped element to move. This movement of the plunger-shaped element may shift the electrical connection between the power source 144 and the transformer 148 to the closed state (i.e., from the open state). Further, upon releasing of the plunger-shaped element, the spring may return to its original position, and may shift the electrical connection from the closed state to the open state.
[0023] It should be noted that the power circuit system 140 for the cooking appliance 100 is not limited to only four transformers 148a, 148b, 148c, 148d as shown in FIGS. 2 and 3. The power circuit system 140 may include any number of transformers 148, each with corresponding spark generator 152a, 152b, 152c, 152d associated with the corresponding burner 112a, 112b, 112c, 112d.
[0024] Referring to FIG. 4, working of the cooking appliance 100 is described. In some embodiments, the actuator 108 may be configured to be actuated to a first actuation stage, to a second actuation stage, and to a third actuation stage. In some embodiments, the actuator 108 may be actuated to the second actuation stage in subsequence to the first actuation stage. Further, the actuator 108 may be actuated to the third actuation stage in subsequence to the second actuation stage. Details of all actuation stages are described below:
First actuation stage:
[0025] In the first actuation stage, the actuator 108 may actuate the switch 156 to shift the electrical connection between the power source 144 and the transformer 148 from the open state to the closed state. In other words, upon actuating the actuator 108 in the first actuation stage, the engaging mechanism 160 may be configured to shift the electrical connection to the closed state. For example, in the closed state, the circuit between the power source 144 and the transformer 148 may be closed, allowing current to flow from the power source 144 to the transformer 148. For example, in the closed state, the power source 144 may provide a first power signal V1 at the primary terminal T1 of the transformer 148. Upon receiving the first power signal V1 from the power source 144, the transformer 148 may convert or amplify the first power signal V1 into a second power signal V2 at the secondary terminal T2. The second power signal V2 from the second terminal T2 may then be supplied to the spark generator 152 to generate a spark. For example, once the electrical connection is switched to the closed state, the spark generator 152 may receive the second power signal V2 to generate the spark.
[0026] In some embodiments, the power source 144 may include but is not limited to a cell or a battery, such as a removable or replaceable AAA, AA, or any suitable type of battery, to provide the first power signal V1. For example, the power source 144 may have a capacity ranging between 1.5 to 3.0 volts, thereby providing the first power signal V1 ranging between 1.5 to 3.0 volts. In some embodiments, the power source 144 may include a rechargeable battery with a requisite milliampere-hour (mAh) rating. In some embodiments, the transformer 148 may be configured to convert or amplify a low voltage of the first power signal V1 input to a high voltage output of the second power signal V2 by applying principles of electromagnetic induction. In some embodiments, the second power signal is greater than the first power signal. For example, the transformer 148 may step up the voltage of the first power signal V1 to provide the second power signal V2 ranging between 8 to 9 kilovolts.
Second actuation stage:
[0027] In some embodiments, the actuator 108 may be actuated to the second actuation stage to move the valve 128 to the first condition. For example, the actuator 108 may be configured to move the valve 128 to the first condition to regulate and provide the supply of the gas from gas source S to the burner 104. Accordingly, in the second actuation stage, the actuator 108 may be configured to move the valve 128 to the first condition such that the gas received from the fuel injector nozzle 136 is supplied to the burner 112. In other words, upon actuating the actuator 108 in the second actuation stage, the valve 128 may be configured to permit the gas to flow from the gas source S to the manifold 116 via the first passage 124. The gas from the manifold 116 may then be supplied to the burner 112 (respectively via the inlet 129, the outlet 129, and the pipeline 132). Accordingly, the actuator 108 may be actuated to control the valve 128 to allow (or regulate) the supply of the gas from the gas source S to the burner 112. To this end, upon moving the valve 128 to the first condition, the gas reaches up to the burner and is released from the burner 112 such that the gas comes in contact with the spark (continued to be produced during the second actuation stage). The contact between the spark and the gas causes the ignition (or combustion) of the gas and production of the flame from the burner 112. In the second actuation stage, the actuator 108 may retain the electrical connection (thus the switch 156) in the closed state.
Third actuation stage:
[0028] In the third actuation stage (followed by the first and second actuation stages), the actuator 108 may be configured to actuate the switch 152 to shift the electrical connection between the power source 144 and the transformer 148 to the open state. For example, upon actuating the actuator 108 in the third actuation stage, the engaging mechanism 160 may be configured to shift the electrical connection to the open state to diffuse or to remove the spark from the spark generator. In the third actuation stage, the actuator 108 may retain the valve in the first condition
[0029] In some embodiments, the actuator 108 may be actuated to the first, second, and third actuation stages via one or more actions including but not limited to rotating, sliding, or moving of the actuator 108, that may be performed by the user. In an exemplary embodiment, the actuator 108 may be configured to be pressed to a pressed state by the user to provide the first actuation stage of the actuator 108. In the first actuation stage, the actuator 108 may actuate the switch 156 to shift the electrical connection between the power source 144 and the transformer 148 from the open state to the closed state. In the closed state, the spark generator 152 may produce the spark at the predetermined distance from the burner 112. In subsequence to the first actuation stage, the actuator 108 may be rotated in an anticlockwise direction d1 or a clockwise direction d2 (as shown in FIGS. 1 and 2) by the user to move the actuator 108 to the second actuation stage. In the second actuation stage, the actuator 108 is configured to move the valve 128 to the first condition such that the gas received from the fuel injector nozzle 136 is supplied to the burner 112.
[0030] Upon moving the valve 128 to the first condition, the gas may be released from the burner 112 and comes in the contact with the spark. The contact between the spark and the gas causes the ignition (or combustion) of the gas and production of the flame from the burner 112. In the second actuation stage, the actuator 108 may retain the switch 156 in the closed state. In subsequence to the second actuation stage, the actuator 108 may be released (from the pressed state), thereby actuating the switch 156 to shift the electrical connection between the power source 144 and the transformer 148 from the closed state to the open state, as a result, halting spark generation.
[0031] Referring to FIG. 5, a method 200 of operating the cooking appliance 100 is described. The method 200 may include a step 201 of producing the first power signal V1 by actuating at least one actuator 108 in the first actuation stage. The method 200 may include a step 202 of receiving the first power signal V1 by the one transformer 148 to convert or amplify the first power signal V1 into the second power signal V2. The method 200 may include a step 203 of receiving the second power signal V2 by the spark generator 152 to produce the spark. The method 200 may include a step 204 of moving the valve 128 to the first condition by actuating the one actuator 108 in the second actuation stage to supply the gas to the one burner 112. The method 200 may include a step 205 of igniting the gas released from the one burner 112 using the spark produced by the spark generator 152.

INDUSTRIAL APPLICABILITY
[0032] The present invention relates to the cooking appliances 100 with the power circuit system 140 and the method of operating the same. The user may use the cooking appliance 100 to produce the flame and generate the heat through the burner 112. In this regard, the user may actuate the actuator 108 to the first actuation stage to switch the electrical connection between the power source 140 and the transformer 148 (with the switch 156) from the open state to the closed state. In this scenario, the first power signal from the power source 140 to the transformer 148 may get converted into the second power signal. The second power signal may receive by the spark generator 152 to produce the spark. Further, the user may actuate the actuator 108 to the second actuation stage to move the valve 128 to the first condition such that the gas received from the fuel injector nozzle 136 is supplied to the burner 112 and retains the switch 156 in the closed state. Accordingly, the spark may cause the ignition of the gas released from the burner 112 thus, producing the flame and generating the heat. Further, the actuator 108 may be actuated to the third actuation stage to actuate the switch 156 to shift the electrical connection between the power source 140 and the transformer 148 to the open state and retains the valve 128 in the first condition. While deactivating the cooking appliance 100 after a usage, the user may simply actuate the actuator 108 from the third actuation stage directly to the first actuation stage.
[0033] The cooking appliance 100 may provide several advantages over traditional piezoelectric cooking appliances. For example, by allowing the specific actuator 108 (from the actuators 108a, 108b, 108c, 108d) to control the corresponding burner 112 (from the burners 112a, 112b, 112c, 112d), the cooking appliance 100 may prevent unnecessary wear on other actuators and burners when only one is in use. Accordingly, this leads to the production of the spark only by the corresponding spark generator 152 that may enhance the lifespan of the spark generator 152 by producing sparks only when required. To this end, the cooking appliance 100 may allow the user to efficiently conserve electrical energy from the power source 144 and the gas from the gas supply S. Moreover, the cooking appliance 100 may be operated independently of external energy due to the power source 144, which may be integrated with the power circuit system 140, allowing the user to utilize the cooking appliance 100 in locations with no power outage. Compared to the traditional piezoelectric cooking appliances, the present cooking appliance 100, with the power circuit system 140, may provide greater reliability, reduced risk of accidental gas leaks, improved control, and extended durability of components.
