Description

Technical Field

[0001] This invention relates to the field of gas stove technology, and in particular to a stove. Background Technology

[0002] Gas stoves are a common kitchen appliance used to meet users' cooking needs. Currently, gas stoves typically use dry cell batteries to power their igniters, flame failure devices, and other components. However, using dry cell batteries requires regular replacement, which can be inconvenient for users.

[0003] In particular, with the continuous improvement of the intelligence level of home appliances, cooktops can be linked and controlled with other home appliances. When cooktops are linked with other home appliances, battery consumption will increase further, thereby increasing the frequency of battery replacements and reducing the user experience.

[0004] Therefore, it is necessary to propose a stove that solves at least one of the above problems. Summary of the Invention

[0112] The applicant discovered that the greater the temperature difference between the hot and cold ends of a thermoelectric chip, the better it is for increasing power generation. However, in current gas stoves that utilize thermoelectric chips to absorb waste heat for power generation and store it in batteries, the hot and cold ends of the chips cannot form a large temperature difference, resulting in low power generation efficiency. The power generation still cannot meet the high power consumption demands of gas stoves in various scenarios such as ignition, linkage, and security.

[0113] This invention provides a stove in which a thermoelectric generator is located in a preferred position in the middle, away from the left and right burners. While absorbing the residual heat from the left and right burners, the thermoelectric generator also improves the heat dissipation performance of the cold end, ensuring a large temperature difference between the hot and cold ends.

[0114] Please refer to the following for comprehensive information. Figures 1 to 10This application specification provides a stove, which may include: a left burner 11 and a right burner 12, the left burner 11 and the right burner 12 being located on the left and right sides of the stove, respectively; a rechargeable battery 2, the rechargeable battery 2 being used to supply the power required for the stove to operate; a thermoelectric generator 3 directly or indirectly electrically connected to the rechargeable battery 2, the thermoelectric generator 3 being disposed between the left burner 11 and the right burner 12 and located in the middle of the stove, the thermoelectric generator 3 having a cold end and a hot end; and a heat sink 7 located in the middle of the stove, the heat sink 7 being connected to the thermoelectric generator 3. The cold ends are in direct or indirect contact; a left heat collector 41 is disposed near the left burner 11; a right heat collector 42 is disposed near the right burner 12; a left heat transfer element 51 is used to connect the hot end of the thermoelectric generator 3 to the left heat collector 41; a right heat transfer element 52 is used to connect the hot end of the thermoelectric generator 3 to the right heat collector 42; a heat dissipation element 7 is used when the stove is working, the thermoelectric generator 3 is used to convert part of the heat generated by the left burner 11 and / or the right burner 12 into electrical energy to supply the rechargeable battery 2.

[0115] In this embodiment, the left heat collector 41 and the left heat transfer member 51 can be used to transfer the residual heat of the working left burner 11 to the hot end of the thermoelectric generator 3; the right heat collector 42 and the right heat transfer member 52 can be used to transfer the residual heat of the working right burner 12 to the hot end of the thermoelectric generator 3. Since the thermoelectric generator 3 is located in a better position in the middle away from the left burner 11 and the right burner 12, the cold end of the thermoelectric generator 3 can be separated from the left burner 11 and the right burner 12 by a large distance. At the same time, the cold end of the thermoelectric generator 3 is provided with a heat dissipation member 7. Since the heat dissipation member 7 is also located in a better position in the middle away from the left burner 11 and the right burner 12, the heat dissipation member 7 itself is not easily affected by the heat radiation of the right burner 12 and the left burner 11. At the same time, it can ensure that the cold end of the thermoelectric generator 3 can be effectively dissipated by the heat dissipation member 7 without being excessively affected by the heat radiation of the working right burner 12 and / or the left burner 11. Overall, the stove provided in this application utilizes a thermoelectric generator 3 to absorb the waste heat from the left burner 11 and the right burner 12, while also ensuring a large temperature difference between the cold and hot ends of the thermoelectric generator 3 to generate sufficient power, thereby meeting the high power consumption demand of the gas stove.

[0116] In this application, the description mainly focuses on a dual-burner stove with a left burner 11 and a right burner 12. Of course, in other scenarios where the stove has more or fewer burners, adjustments can be made accordingly, and these will not be described in detail here.

[0117] The stove may include: a shell 10, a left burner 11, a right burner 12, a rechargeable battery 2, a thermoelectric generator 3, a left heat collector 41, a right heat collector 42, a left heat transfer element 51, a right heat transfer element 52, and a heat dissipation element 7, etc. Please refer to the following: Figure 2 and Figure 4 The housing 10 can be a hollow structure. Specifically, the housing 10 can include a bottom shell 14 and a panel 13 disposed on the bottom shell 14. The panel 13 can be detachably mounted on the bottom shell 14. Specifically, the panel 13 can be a rectangular panel 13 with a certain thickness. The panel 13 can have a left opening for positioning the left burner 11 and a right opening for positioning the right burner 12. The bottom shell 14 can be used to install components such as the rechargeable battery 2 and the thermoelectric generator 3. The bottom shell 14 can be a cavity structure with an open top. The bottom shell 14 can include a bottom wall 141 and side walls 142 surrounding the bottom wall 141. The circumferential contour of the side wall 142, which is parallel to the panel 13, can be rectangular or rectangular to facilitate installation with the mounting holes reserved in the user's kitchen.

[0118] like Figure 3 As shown, the housing 10 is located along the left-right direction (i.e. Figure 3 A left burner 11 and a right burner 12 are spaced apart on the first direction (X) shown. Specifically, the left burner 11 is positioned on the left side of the stove through the left opening, and the right burner 12 is positioned on the right side of the stove through the right opening.

[0119] The left burner head 11 and the right burner head 12 may have the same or similar structures. In this embodiment, one of the burner heads, for example... Figure 9 The left burner head 11 is used as an example for detailed illustration. The structure of the right burner head 12 can be referred to the left burner head 11, and will not be repeated here. The left burner head 11 may include an inner burner cap and an outer burner cap, and the left burner head 11 also has an internal gas outlet and an external gas outlet. The inner burner cap is installed on the internal gas outlet, which is connected to an internal gas ejector pipe. Gas flowing in from the internal gas ejector pipe can flow out through the internal gas outlet and be ejected from the hole opened on the inner burner cap. The outer burner cap is installed on the external gas outlet, which is connected to an outer ring gas ejector pipe. Gas flowing in from the external gas ejector pipe can flow out through the external gas outlet and be ejected from the hole opened on the outer burner cap.

[0120] like Figure 3As shown, the thermoelectric generator 3 is disposed between the left burner 11 and the right burner 12 and located in the middle of the stove. Specifically, the composition and form of the thermoelectric generator 3 are not limited here. For example, the thermoelectric generator 3 may include only one thermoelectric generator unit or multiple thermoelectric generator units. When the thermoelectric generator 3 includes multiple thermoelectric generator units, it may include two or more thermoelectric generator units, which may be connected in series and / or in parallel. The thermoelectric generator 3 as a whole can be a rectangular structure with a certain thickness. Of course, the construction of the thermoelectric generator 3 can also be other structures, which are not specifically limited here.

[0121] The thermoelectric generator 3 has a cold end and a hot end. The inventors of this application have discovered that currently, after the heat generated during combustion in the burner is transferred to the hot end, the temperature of the hot end can basically rise to its limit, making it difficult to further increase the temperature, or in other words, the increase is relatively limited, and its effect on widening the temperature difference between the hot and cold ends is not significant. Based on this, in order to widen the temperature difference between the hot and cold ends, one of the key improvements in this application is to improve the heat dissipation performance of the cold end and effectively control its temperature.

[0122] Along the thickness direction, the hot end can be located on the upper surface of the thermoelectric generator 3, and the cold end can be located on the lower surface of the thermoelectric generator 3. This allows the cold end to be further away from the left burner 11 and right burner 12 in the longitudinal direction, which is more conducive to ensuring effective heat dissipation from the cold end and thus increasing the temperature difference between the cold and hot ends. Furthermore, compared to the cold end located on the lower surface, the hot end located on the upper surface can come into contact with higher-temperature components (such as the panel 13 of the housing 10) for heat transfer, thereby increasing the temperature of the hot end and further increasing the temperature difference between the hot and cold ends, ensuring that the thermoelectric generator 3 can generate sufficient power. For this stove, the left burner 11 and right burner 12 can be arranged symmetrically in the first direction X.

[0123] The thermoelectric generator 3 can be located between the two burners, in the middle of the stove. This ensures that the cold end of the thermoelectric generator 3 is relatively far from either the left burner 11 or the right burner 12, preventing the temperature of the cold end from becoming excessively high due to the influence of the burners. This, in turn, helps to maintain a large temperature difference between the cold and hot ends of the thermoelectric generator 3, resulting in sufficient power generation. Furthermore, when the thermoelectric generator 3 is located in the middle of the stove, it fully utilizes the space in the central area without requiring modifications to the stove's internal valves, piping, etc., and without increasing the size of the casing 10. This reduces manufacturing costs and processing difficulty.

[0124] Specifically, the ratio of the distance from the center of the thermoelectric generator 3 to the center of the left burner 11 to the distance from the center of the thermoelectric generator 3 to the center of the right burner 12 is between 0.8 and 1.2. The distance from the center of the thermoelectric generator 3 to the center of the left burner 11 is L1, and the distance from the center of the thermoelectric generator 3 to the center of the right burner 12 is L2. The ratio of L1 to L2 can be between 0.8 and 1.2, thereby ensuring that the cold end of the thermoelectric generator 3 is not affected by the burner and its temperature is not too high.

[0125] Furthermore, the distance from the center of the thermoelectric generator 3 to the center of the left burner 11 is equal to the distance from the center of the thermoelectric generator 3 to the center of the right burner 12.

[0126] In this embodiment, the center of the thermoelectric generator 3 can be located on the perpendicular bisector EE of the line connecting the center of the left burner 11 and the center of the right burner 12. When the center of the thermoelectric generator 3 is on the perpendicular bisector EE, its distance from the center of the left burner 11 is equal to its distance from the right burner 12. This ensures that the cold end of the thermoelectric generator 3 is spaced far from both the left burner 11 and the right burner 12. Whether the left burner 11 is working, the right burner 12 is working, or both the left burner 11 and the right burner 12 are working simultaneously, the temperature of the cold end of the thermoelectric generator 3 can be effectively controlled and will not rise excessively.

[0127] In this embodiment, the rechargeable battery 2 is used to supply the power required for the stove to operate. When the stove is operating, the thermoelectric generator 3 is used to convert part of the heat generated by the left burner 11 and / or the right burner 12 into electrical energy to supply the rechargeable battery 2.

[0128] In one embodiment, the stove may further include a voltage regulator module 6, which is electrically connected to the thermoelectric generator 3 and also electrically connected to the rechargeable battery 2. The voltage regulator module 6 is used to control the voltage for charging the rechargeable battery 2 within a predetermined voltage range.

[0129] In this embodiment, the voltage regulator module 6 can be connected between the thermoelectric generator 3 and the rechargeable battery 2. The operating voltage of the rechargeable battery 2 is within a predetermined operating voltage range, for example, between 3.3 volts and 3.5 volts. The voltage regulator module 6 is used to control the voltage generated by the thermoelectric generator 3 within a predetermined voltage range, which covers the operating power range of the rechargeable battery 2. For example, the predetermined voltage range can be between 3 volts and 5 volts, thereby ensuring that the thermoelectric generator 3 can reliably, effectively, and safely charge the rechargeable battery 2.

[0130] In some embodiments, the cooking appliance may include a communication module through which the cooking appliance can communicate with designated household appliances. The communication module is electrically connected to the battery, and the battery can supply power to the communication module.

[0131] In this embodiment, the cooking appliance may be provided with a communication module for communicating with other household appliances to achieve a linkage function. Specifically, the communication module may adopt any feasible module in the prior art, and no limitation is imposed on it in this application. For example, the communication module may be a Bluetooth module, a Wi-Fi module, a ZigBee wireless communication module, a wireless data transmission module, etc.

[0132] Generally, the communication module is in an always-on state and continuously consumes power. However, for the cooking appliance provided in the embodiment of this application, through the optimized design of the structures, relative positional relationships, cooperation relationships, etc. of the various components that implement the self-power generation function in the cooking appliance, including the thermoelectric power generation element 3, the heat dissipation element 7, etc., the rechargeable battery 2 can meet the large power demand of the communication module.

[0133] Among them, the designated household appliances may include any one or a combination of the following: range hood, steam box, oven, dishwasher. Of course, the designated household appliances may also be other forms that can be linked with the cooking appliance, and are not limited to the above description. Those skilled in the art may make other changes under the inspiration of the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they should all be covered within the protection scope of this application.

[0134] For example, taking the range hood as an example, when the cooking appliance is started, the communication module can be used to send a startup instruction to the range hood, thereby automatically turning on the range hood, which can reduce the operation of the user to turn on the range hood and improve the user experience.

[0135] For example, taking the cooking devices (steam box, oven, steam oven) in the kitchen as an example, when the cooking appliance is started, the communication module can be used to send a setting control instruction, such as a startup instruction, to the cooking device. At this time, the cooking device can also be automatically turned on, so that the cooking device and the cooking appliance start working synchronously, reducing the operation of the user to start the cooking device and improving the user experience.

[0136] Please refer to Figure 7 and Figure 8 , in this embodiment, the heat dissipation element 7 is mainly used to dissipate heat and cool down the cold end of the thermoelectric power generation element 3, and the position of the heat dissipation element 7 can match the position of the thermoelectric power generation element 3. Specifically, the heat dissipation element 7 may be located in the middle of the cooking appliance and the heat dissipation element 7 is directly or indirectly in contact with the cold end of the thermoelectric power generation element 3. The contact method may be different according to the different cooperation relationships between the cold end of the thermoelectric power generation element 3 and the heat dissipation element 7.

[0137] The cold end of the thermoelectric generator 3 can be directly or indirectly attached to the heat sink 7, thereby increasing the heat exchange area between the cold end and the heat sink 7. Specifically, the heat sink 7 includes a substrate 71 and heat dissipation fins 72 disposed on the substrate 71. The shape and structure of the substrate 71 can be adapted to the shape and structure of the cold end of the thermoelectric generator 3. For example, when the thermoelectric generator 3 is a rectangular structure with a certain thickness, the substrate 71 can be a rectangular plate with a certain thickness. A plurality of heat dissipation fins 72 can be disposed on the lower surface of the substrate 71, and the heat dissipation fins 72 can be evenly spaced at a certain distance. The heat dissipation fins 72 can specifically be aluminum fins with good heat dissipation performance. The specific structure, layout, and materials of the heat dissipation fins 72 are not specifically limited herein.

[0138] The upper surface of the substrate 71 can be directly or indirectly attached to the cold end, thereby ensuring that there is a large heat exchange area between the substrate 71 and the cold end of the thermoelectric generator 3, thus achieving an ideal heat dissipation effect.

[0139] For example, when the cold end of the thermoelectric generator 3 is directly attached to the substrate 71 of the heat sink 7, without considering manufacturing and installation errors, the cold end and the substrate 71 of the heat sink 7 can be in surface-to-surface contact, thereby ensuring that the cold end and the substrate 71 have the largest contact area.

[0140] Alternatively, when the cold end of the thermoelectric generator 3 is indirectly in contact with the substrate 71 of the heat sink 7, a heat-conducting medium is provided between the cold end of the thermoelectric generator 3 and the substrate 71 of the heat sink 7. The cold end of the thermoelectric generator 3 and the substrate 71 of the heat sink 7 are indirectly in contact through the heat-conducting medium, thereby ensuring that the cold end of the thermoelectric generator 3 and the substrate 71 of the heat sink 7 have the largest heat exchange area and better thermal conductivity, so that the cold end of the thermoelectric generator 3 can be effectively cooled down.

[0141] Specifically, the thermally conductive medium can be thermally conductive silicone grease. Thermally conductive silicone grease is a highly thermally conductive and insulating silicone material that almost never cures and can maintain its grease-like state for a long time at temperatures ranging from -50℃ to +230℃. It has both excellent electrical insulation and excellent thermal conductivity.

[0142] When the thermally conductive silicone grease is filled between the cold end of the thermoelectric generator 3 and the substrate 71 of the heat sink 7, it ensures a zero-gap fit between the cold end of the thermoelectric generator 3 and the substrate 71 of the heat sink 7, thus assisting the heat sink 7 in achieving better heat conduction and dissipation for the cold end of the thermoelectric generator 3. Of course, the thermally conductive medium can also be other materials, and this application does not specifically limit the specific material of the thermally conductive medium.

[0143] In one embodiment, the area of ​​the substrate 71 is greater than or equal to the area of ​​the cold end of the thermoelectric generator 3. When the area of ​​the substrate 71 is greater than or equal to the area of ​​the cold end of the thermoelectric generator 3, the substrate 71 of the heat sink 7 can cover the entire cold end of the thermoelectric generator 3, thereby achieving efficient heat conduction and dissipation of the cold end of the thermoelectric generator 3.

[0144] Furthermore, in order to ensure better thermal conductivity and heat dissipation between the cold end of the thermoelectric generator 3 and the substrate 71 of the heat sink 7, a thermally conductive medium can be filled in the gap between the cold end of the thermoelectric generator 3 and the substrate 71 of the heat sink 7.

[0145] like Figure 7 As shown, in one embodiment, the stove may further include a clamping member 8, the thermoelectric generator 3 is located between the clamping member 8 and the heat dissipation member 7, the clamping member 8 is connected to the base plate 71 of the heat dissipation member 7, and is used to make the base plate 71 of the heat dissipation member 7 contact with the cold end of the thermoelectric generator 3.

[0146] In this embodiment, the stove may further include a clamping member 8, which is used to clamp the cold end of the thermoelectric generator 3 and the base plate 71 of the heat sink 7. Specifically, the clamping member 8 may be located at the upper part of the thermoelectric generator 3, while the heat sink 7 may be located at the lower part of the thermoelectric generator 3. When the clamping member 8 is connected to the base plate 71 of the heat sink 7, the base plate 71 of the heat sink 7 and the cold end of the thermoelectric generator 3 can be pressed tightly together, avoiding the two from not being tightly attached due to manufacturing and installation errors, which would affect the heat exchange efficiency between them.

[0147] The shape and structure of the clamping member 8 are not limited in this application. For example, the clamping member 8 may be plate-shaped and cover the upper part of the thermoelectric generator 3; the clamping member 8 may be U-shaped and fastened to the thermoelectric generator 3; or the clamping member 8 may be other shapes and structures.

[0148] In one specific embodiment, the clamping member 8 can be connected to the substrate 71 via a connector. The connector is respectively disposed on opposite sides of the clamping member 8 and the substrate 71 to ensure that the substrate 71 and the clamping member 8 are subjected to uniform force in the circumferential direction, thereby ensuring that the clamping member 8 and the substrate 71 can be tightly and uniformly attached.

[0149] Specifically, the number of connectors is at least four. The clamping member 8 is a clamping plate, and each of the four corners of the clamping plate is connected to the base plate 71 via a connector. The connectors can be bolts or screws, ensuring a tighter and more uniform fit between the clamping member 8 and the base plate 71. When the connector is a bolt or screw, both the clamping member 8 and the base plate 71 have holes for the bolt or screw to pass through. Of course, the connector can also be in other forms. When the connector is a detachable bolt or screw, its installation and manufacturing costs are low, making it easy to mass-produce and reduce costs.

[0150] Please refer to the following: Figures 7 to 8 In this embodiment, the thermoelectric generator 3 has an upper surface and a lower surface, the upper surface includes the hot end, the lower surface includes the cold end, and the heat sink 7 is located below the cold end of the thermoelectric generator 3.

[0151] When the heat sink 7 is located below the cold end of the thermoelectric generator 3, the cold end of the thermoelectric generator 3 and the heat sink 7 are arranged away from the heat source (left burner 11 and right burner 12) in sequence, which helps to ensure that the cold end of the thermoelectric generator 3 can be reliably cooled by the heat sink 7 located below the cold end.

[0152] Please refer to the following: Figure 4 and Figure 9 In one embodiment, the stove further includes a bottom shell 14 and a panel 13 disposed on the bottom shell 14. The thermoelectric generator 3 is disposed between the bottom shell 14 and the panel 13. An opening 1411 is provided in the middle of the bottom shell 14 for the heat sink 7 to pass through. At least part of the heat sink 7 protrudes downward from the bottom shell 14 through the opening 1411.

[0153] In this embodiment, the bottom shell 14 of the stove may include a bottom wall 141 and side walls 142 surrounding the bottom wall 141. An opening 1411 may be provided in the middle of the bottom wall 141, and a heat sink 7 may be inserted through the opening 1411. At least a portion of the heat sink 7 protrudes from the outer surface of the bottom wall 141 through the opening 1411. In this way, the heat sink 7 can connect the outside air with the inside of the stove shell 10, and the outside air can directly contact the heat sink 7, thereby carrying away the heat on the heat sink 7, i.e., dissipating heat from the heat sink 7, reliably controlling the temperature rise of the heat sink 7, and thus ensuring that the heat sink 7 reliably dissipates and cools the cold end of the thermoelectric generator 3.

[0154] Furthermore, an airflow gap is formed between the heat sink 7 and the opening 1411. When the left burner 11 and / or the right burner 12 are working, external air can flow through the heat sink and through the airflow gap to the left burner 11 and / or the right burner 12.

[0155] In this embodiment, an airflow gap can also be formed between the heat sink 7 and the opening 1411. For example, at least one sidewall of the heat sink 7 can be clearance-fitted with the opening 1411 to form an airflow gap; or the heat dissipation fins 72 of the heat sink 7 can be partially located inside the housing 10 and partially located outside the housing 10 along the depth direction (perpendicular to the first direction X and the second direction Y), and an airflow gap can be formed by utilizing the gap between adjacent heat dissipation fins 72, which can also connect the outside and inside of the housing 10. Using this airflow gap, external air can flow through the heat sink 7, thereby dissipating heat from the heat sink 7, reliably controlling the temperature rise of the heat sink 7, and thus ensuring that the heat sink 7 reliably dissipates and cools the cold end of the thermoelectric generator 3.

[0156] Please refer to the following: Figures 5 to 6 When the stove is in operation, air from outside the casing 10 is introduced as primary air and supplied to the left burner 11 and / or the right burner 12 to provide the oxygen required for combustion. Specifically, when the gas at the left burner 11 and / or the right burner 12 passes through the nozzle, it draws in the surrounding air to form primary air. During the formation of primary air, ambient air from outside the casing 10 flows into the burner at a relatively fast speed.

[0157] In this embodiment, the flow path of ambient air can be cleverly controlled during the process of introducing ambient air into the left burner 11 and / or the right burner 12. The ambient air with a relatively fast flow rate is used to flow through the heat sink 7 before flowing into the left burner 11 and / or the right burner 12, thereby dissipating heat from the heat sink 7. This not only improves the heat dissipation effect of the heat sink 7 itself, but also further enhances the heat dissipation and cooling effect of the heat sink 7 on the cold end of the thermoelectric generator 3.

[0158] The shape and structure of the opening 1411 can be adapted to the outer contour of the heat sink 7. For example, when the outer contour of the heat sink 7 is rectangular, the shape of the opening 1411 can also be rectangular. The size of the opening 1411 can be equal to or greater than the cross-sectional size of the outer contour of the heat sink 7.

[0159] Specifically, the opening 1411 has opposing left and right side walls. Furthermore, the opening 1411 may also have a front and rear side wall, which can be sequentially connected to form a rectangular opening. A left airflow gap 1413 is formed between the left side wall and the heat sink 7, and a right airflow gap 1414 is formed between the right side wall and the heat sink 7.

[0160] When the stove is working, taking the left burner 11 and right burner 12 as examples, when the primary air is generated, the ambient temperature air from outside is introduced into the housing 10 through the left airflow gap 1413 and the right airflow gap 1414 and guided to the left burner 11 and right burner 12. At least part of the air can come into contact with the heat sink 7. After passing through the left airflow gap 1413 and the right airflow gap 1414, it is guided to the left burner 11 and right burner 12. This ensures that the air flowing into the housing 10 from outside can come into contact with the heat sink 7 for heat exchange during the flow process, so as to reliably control the temperature rise of the heat sink 7 and further improve the heat dissipation and cooling effect of the heat sink 7 on the cold end of the thermoelectric generator 3.

[0161] In one specific embodiment, the heat sink 7 has a plurality of spaced-apart heat sink fins 72, each of which protrudes at least partially from the bottom shell 14. The heat sink fins 72 extend in a left-right direction to form airflow channels 720 in the left-right direction. External ambient temperature air can flow through the airflow channels 720 and then through the left airflow gap 1413 and the right airflow gap 1414 to the left burner head 11 and the right burner head 12, respectively.

[0162] In this embodiment, the heat sink 7 includes a plurality of spaced-apart heat sink fins 72. When the heat sink 7 is installed in place, the heat sink fins 72 extend along the left-right direction (i.e., Figure 3 The heat sink fins extend in the first direction (X) and at least partially protrude from the bottom shell 14, and an airflow channel 720 is formed between two adjacent heat sink fins 72 in the left-right direction. The airflow channel 720 extends directly toward the left burner 11 and the right burner 12.

[0163] When the stove is working, due to the ejection effect of the nozzle, a portion of the ambient temperature air can flow at a relatively fast speed through the airflow channel 720 and through the left airflow gap 1413 and the right airflow gap 1414 to the left burner 11 and the right burner 12 respectively. A portion of the ambient temperature air can also flow directly to the left burner 11 and / or the right burner 12 through the left airflow gap 1413 and the right airflow gap 1414.

[0164] For example, taking the case where both the left burner 11 and the right burner 12 are in operation, under the ejection action of the nozzle of the left burner 11, a portion of the ambient temperature air can flow to the left burner 11 at a relatively fast speed through the airflow channel 720 and the left airflow gap 1413, as well as directly through the left airflow gap 1413; under the ejection action of the nozzle of the right burner 12, a portion of the ambient temperature air can flow to the right burner 12 at a relatively fast speed through the airflow channel 720 and the right airflow gap 1414, as well as directly through the right airflow gap 1414.

[0165] Taking the case where only the left burner 11 is in operation, under the ejection action of the nozzle of the left burner 11, the ambient temperature air outside can flow through the airflow channel 720, through the left airflow gap 1413 and the right airflow gap 1414 to the left burner 11 at a relatively fast speed. In addition, some ambient temperature air can also flow directly through the left airflow gap 1413 to the left burner 11 at a relatively fast speed.

[0166] When only the right burner 12 is in operation, under the ejection action of the nozzle of the right burner 12, the ambient temperature air outside can flow through the airflow channel 720, through the left airflow gap 1413 and the right airflow gap 1414 to the right burner 12 at a relatively fast speed. In addition, some ambient temperature air can also flow directly through the right airflow gap 1414 to the right burner 12 at a relatively fast speed.

[0167] In this way, the heat dissipation fins 72 of the heat dissipation component 7 and the cooperation between the heat dissipation component 7 and the bottom shell 14 form a primary airflow channel for air intake to the furnace head. At the same time as forming this primary airflow channel, the ambient temperature air flowing in from the outside can flow through the airflow channel 720 between the heat dissipation fins 72, thereby reliably and efficiently dissipating and cooling the heat dissipation fins 72, and thus ensuring that the temperature of the cold end of the thermoelectric generator 3 is controlled at a low temperature.

[0168] Among them, since the heat dissipation fins 72 are along the left and right direction (i.e. Figure 3 The first direction (X) of the heat sink extends, which also helps the air flowing through the heat sink fin 72 to be accurately guided to the left burner 11 and / or the right burner 12 with a shorter path and lower resistance.

[0169] like Figure 9 As shown, the opening 1411 also has opposing front and rear sidewalls. Both the front and rear sidewalls are provided with flanges 1412, which are used to connect with the heat sink 7.

[0170] Specifically, the flange 1412 may be provided with at least one connector, which can be used to connect the flange 1412 to the heat sink 7. For example, taking the flange 1412 of the front sidewall as an example, the flange 1412 may be provided with two openings, each opening through which a connector can be used to connect the heat sink 7 to the bottom shell 14. The connector may be in the form of a detachable connection such as a bolt or screw, or other methods, which are not specifically limited here.

[0171] like Figure 4 As shown, in one embodiment, a boss 143 is provided in the middle of the bottom shell 14, the boss 143 protrudes from the outside to the inside, and the opening 1411 is provided on the boss 143.

[0172] In this embodiment, a boss 143 protruding from the outside to the inside can be provided in the middle of the bottom wall 141 of the bottom shell 14, and the opening 1411 can be provided on the boss 143. Since a heat sink 7 is installed in the opening 1411, and the heat sink 7 protrudes partially from the bottom wall 141 after passing through the opening 1411, when the boss 143 protrudes inward, it can prevent the heat sink 7 protruding from the bottom wall 141 from interfering with the external installation environment. In addition, when a boss 143 protruding from the outside to the inside is provided and the heat sink 7 passes through the opening 1411 of the boss 143, it is equivalent to using the boss 143 to form an air circulation section higher than other positions of the bottom wall 141. External air can flow more smoothly and reliably through this air circulation section to the airflow channel 720, the left airflow gap 1413 and the right airflow gap 1414 of the heat sink 7 with lower resistance, thereby enabling better reliable and efficient heat dissipation and cooling of the heat sink 7, and thus ensuring that the cold end temperature of the thermoelectric generator 3 is controlled at a lower temperature.

[0173] In addition, such as Figure 4 As shown, in some other embodiments, the bottom shell 14 may also include a bottom wall 141 and a side wall 142 surrounding the bottom wall 141, wherein an air inlet 1421 is provided on the side wall 142.

[0174] By providing an air inlet 1421 on the side wall 142, when the stove is in use, ambient temperature air outside the housing 10 can also enter the housing 10 through the air inlet 1421 under the ejection action of the nozzle, and flow to the left burner 11 and the right burner 12 to achieve the air intake function.

[0175] Specifically, the air inlet 1421 is located close to the heat sink 7, or the projection of the heat sink 7 toward the side wall 142 at least partially overlaps with the air inlet 1421, so that when the ambient temperature air from outside flows into the housing 10 through the air inlet, it can first flow through the heat sink 7 to dissipate heat before flowing to the left burner 11 and the right burner 12.

[0176] In one embodiment, the projected area of ​​the heat sink 7 toward the cold end is greater than or equal to the area of ​​the cold end. When the projected area of ​​the heat sink 7 toward the cold end is greater than or equal to the area of ​​the cold end, it ensures that the heat sink 7 can adequately dissipate heat from the cold end, achieving the best heat dissipation effect. For example, when the heat sink 7 is directly or indirectly attached to the cold end, the heat dissipation effect is better as the contact area between the two increases.

[0177] When the projected area of ​​the heat sink 7 facing the cold end is larger than the area of ​​the cold end, the part of the heat sink 7 protruding from the cold end can be used to install and position the heat sink 7 itself, or the part of the heat sink 7 protruding from the cold end can be used to cooperate with other components, such as with the clamping component 8, to achieve the installation and positioning of the thermoelectric generator 3.

[0178] In some embodiments, one end of the left heat transfer element 51 is connected to the left heat collector 41, and the other end of the left heat transfer element 51 is directly or indirectly attached to the hot end; and / or, one end of the right heat transfer element 52 is connected to the right heat collector 42, and the other end of the right heat transfer element 52 is directly or indirectly attached to the hot end.

[0179] In this embodiment, the stove may include a left heat collector 41 and a left heat transfer element 51, as well as a right heat collector 42 and a right heat transfer element 52. The shape, structure, connection relationship, and function of the left heat collector 41 and the right heat collector 42 may be the same or similar. In this embodiment, the left-side component is described in detail; the right-side component can be described with reference to the left-side component.

[0180] The left heat collector 41 is positioned near the left burner head 11 and is used to absorb the heat generated by the left burner head 11. The left heat transfer element 51 is connected between the left heat collector 41 and the hot end, and is used to transfer the heat absorbed by the left heat collector 41 to the hot end. The right heat collector 42 is positioned near the right burner head 12 and is used to absorb the heat generated by the right burner head 12. The right heat transfer element 52 is connected between the right heat collector 42 and the hot end, and is used to transfer the heat absorbed by the right heat collector 42 to the hot end.

[0181] Specifically, the left heat transfer element 51 includes a left heat transfer pipe 511 and a left heat transfer plate 512 connected to the left heat transfer pipe 511. One end of the left heat transfer pipe 511 is connected to the left heat collector 41, and the left heat transfer plate 512 is directly or indirectly attached to the hot end; and / or, the right heat transfer element 52 includes a right heat transfer pipe 521 and a right heat transfer plate 522 connected to the right heat transfer pipe 521. One end of the right heat transfer pipe 521 is connected to the right heat collector 42, and the right heat transfer plate 522 is directly or indirectly attached to the hot end.

[0182] The left heat transfer element 51 may take the form of a left heat transfer tube 511 and a left heat transfer plate 512, wherein the left heat transfer tube 511 contains a phase change medium. Specifically, the left heat transfer tube 511 may include: a hollow tube shell, a phase change medium disposed in the tube shell, and an end cap sealed at the end of the tube shell. The left heat transfer tube 511 makes full use of the principle of heat conduction and the rapid heat transfer properties of the phase change medium, and can quickly transfer the heat of the left furnace head 11 to the outside through the left heat transfer tube 511.

[0183] Specifically, one end of the left heat transfer pipe 511 can be connected to the left heat collector 41, and the other end of the left heat transfer pipe 511 can be inserted into the left heat transfer plate 512 or connected to the left heat transfer plate 512. For example, the left heat transfer plate 512 can be provided with a groove or opening for matching the left heat transfer pipe 511. The left heat transfer pipe 511 can be embedded in the groove and connected to the left heat transfer plate 512, or it can be extended into the opening to pass through the left heat transfer plate 512.

[0184] The left heat transfer plate 512 can be in the form of a sheet, and the left heat transfer plate 512 can be directly or indirectly attached to the hot end. For example, when the left heat transfer plate 512 is directly connected to the hot end, the sheet-like left heat transfer plate 512 can be attached to the hot end, that is, the upper surface of the thermoelectric generator 3.

[0185] When the left heat transfer plate 512 is indirectly connected to the hot end, the left heat transfer plate 512 and the hot end can be indirectly attached through a thermally conductive medium, thereby ensuring that the left heat transfer plate 512 and the hot end have the largest contact area and better thermal conductivity, so that the heat of the left heat transfer plate 512 can be effectively transferred to the hot end to increase the temperature of the hot end. Specifically, the thermally conductive medium can be thermally conductive silicone grease. The functions and advantages of this thermally conductive silicone grease can be referred to the specific description in the above embodiments, and will not be repeated here.

[0186] The composition of the right heat transfer element 52 and its relationship with other components can be referred to the description of the left heat transfer element 51 above. When the right heat transfer plate 522 is indirectly connected to the hot end, it can also be indirectly attached to the hot end through a heat-conducting medium. This ensures that the right heat transfer plate 522 and the hot end have the largest contact area and the best thermal conductivity, thereby enabling the heat from the right heat transfer plate 522 to be effectively transferred to the hot end, thus increasing the temperature of the hot end.

[0187] In one embodiment, the heat sink 7 includes a substrate 71 and heat sink fins 72 disposed on the substrate 71. The thermoelectric generator 3 is located between the left heat transfer fin 512 and the substrate 71, the left heat transfer fin 512 being connected to the substrate 71 so that the left heat transfer fin 512 is directly or indirectly fastened to the hot end, and / or the thermoelectric generator 3 is located between the right heat transfer fin 522 and the substrate 71, the right heat transfer fin 522 being connected to the substrate 71 so that the right heat transfer fin 522 is directly or indirectly fastened to the hot end.

[0188] In this embodiment, for the left heat transfer plate 512 on the left side, the thermoelectric generator 3 can be located between the left heat transfer plate 512 and the substrate 71. The left heat transfer plate 512 and the substrate 71 can be connected, thereby pressing the left heat transfer plate 512 against the hot end, maintaining a direct or indirect contact with the hot end. The left heat transfer plate 512 connected to the substrate 71 effectively performs the pressing function.

[0189] For the right heat transfer plate 522 on the right side, the thermoelectric generator 3 can be located between the right heat transfer plate 522 and the substrate 71. The right heat transfer plate 522 and the substrate 71 can be connected, so that the right heat transfer plate 522 is pressed against the hot end, maintaining a close contact with the hot end directly or indirectly. The right heat transfer plate 522 connected to the substrate 71 effectively achieves the pressing function.

[0190] In order to efficiently transfer the heat in the left heat transfer plate 512 and the right heat transfer plate 522 to the hot end, the total area of ​​the left heat transfer plate 512 and the right heat transfer plate 522 is less than or equal to the area of ​​the hot end.

[0191] Specifically, the total area of ​​the left heat transfer plate 512 and the right heat transfer plate 522 accounts for 50%-100% of the area of ​​the hot end.

[0192] When the total area of ​​the left heat transfer plate 512 and the right heat transfer plate 522 accounts for more than 50% of the area of ​​the hot end, it can be ensured that there is a large heat transfer area between the left heat transfer plate 512 and the right heat transfer plate 522 and the hot end, thereby reliably ensuring that the heat in the left heat transfer plate 512 and the right heat transfer plate 522 is efficiently transferred to the hot end.

[0193] Of course, the embodiments of this application do not exclude the possibility that the total area of ​​the left heat transfer plate 512 and the right heat transfer plate 522 accounts for slightly less than 50% of the area of ​​the hot end. For example, the total area of ​​the left heat transfer plate 512 and the right heat transfer plate 522 accounts for 48%, 49%, etc., of the area of ​​the hot end. When the total area of ​​the left heat transfer plate 512 and the right heat transfer plate 522 accounts for slightly less than 50% of the area of ​​the hot end, the heat transfer effect between them and the hot end can also achieve an effect that is basically the same as the minimum boundary value (50%).

[0194] In one embodiment, the left heat transfer plate 512 and the right heat transfer plate 522 are the same common heat transfer plate.

[0195] In this embodiment, the left heat transfer plate 512 and the right heat transfer plate 522 can be a common heat transfer plate. When the left heat transfer plate 512 and the right heat transfer plate 522 are a common heat transfer plate, the left heat transfer element 51 and the right heat transfer element 52 can also be integrated. For example, the left heat transfer element 51 and the right heat transfer element 52 are integrally formed, thereby reducing assembly steps, simplifying the manufacturing process, and reducing production costs. When the left heat transfer element 51 and the right heat transfer element 52 are integrally formed common heat transfer elements, the common heat transfer element can connect the hot end of the thermoelectric generator 3 to the left heat collector 41 and the right heat collector 42.

[0196] Furthermore, the heat sink 7 may include a substrate 71 and heat sink fins 72 disposed on the substrate 71. The common heat transfer plate has at least a flange portion protruding from the hot end, and the flange portion is connected to the substrate 71 via a connector.

[0197] In this embodiment, in addition to its function of transferring heat to the hot end, the common heat transfer plate can also be connected to the substrate 71 via a connector to achieve a clamping function. That is, by setting up this common heat transfer plate, there is no need to set up an additional clamping structure, resulting in a compact and ingenious overall structure.

[0198] Specifically, the common heat transfer plate has a flange portion protruding from the hot end in the projection towards the hot end. This flange portion can be connected to the substrate 71 of the heat sink 7 via a connector, thereby pressing the common heat transfer plate, the thermoelectric generator 3 and the heat sink 7 together to ensure that the mating positions are in close contact. This ensures better heat exchange efficiency between the common heat transfer plate and the hot end, and between the heat sink 7 and the cold end.

[0199] It should be noted that, in this embodiment, the main body of the common heat transfer plate can be a rectangular plate with a structure similar to that of the hot end. Since the common heat transfer plate is provided with a flange portion that protrudes from the hot end, when the area of ​​the main body of the common heat transfer plate is equal to that of the hot end, the total area of ​​the common heat transfer plate can be slightly larger than the area of ​​the hot end.

[0200] In one embodiment, a heat-conducting medium is provided at the position where one end of the left heat transfer element 51 is connected to the left heat collector 41, and / or, a heat-conducting medium is provided at the position where one end of the right heat transfer element 52 is connected to the right heat collector 42.

[0201] In this embodiment, a heat-conducting medium can be provided at the position where the left heat transfer element 51 is connected to the left heat collector 41, so that the position where the left heat transfer element 51 is connected to the left heat collector 41 has the largest contact area and better thermal conductivity.

[0202] A heat-conducting medium can be provided at the location where the right heat transfer element 52 is connected to the right heat collector 42, so that the location where the right heat transfer element 52 is connected to the right heat collector 42 has the largest contact area and better thermal conductivity.

[0203] The thermally conductive medium can be the thermally conductive silicone grease described in the above embodiments, or other materials with excellent thermal conductivity. This application does not make any specific limitations here.

[0204] Please refer to the following: Figure 4 , Figure 7 and Figure 10 In one embodiment, a left liquid receiving tray 15 is provided on the left burner head 11, and a right liquid receiving tray 16 is provided on the right burner head 12.

[0205] In this embodiment, the left heat collector 41 can be connected to the left liquid receiving plate 15, and the right heat collector 42 can be connected to the right liquid receiving plate 16.

[0206] The left liquid receiving tray 15 is provided with a left through hole 151. The left heat collector 41 includes a left main heat receiving part 411 that can pass through the left through hole 151 to directly absorb the heat of the left burner 11, and a left auxiliary heat receiving part 412 that can contact the left liquid receiving tray 15 to indirectly absorb the heat of the left burner 11 through the left liquid receiving tray 15. Specifically, the left heat collector 41 is connected to the left liquid receiving tray 15 through the left auxiliary heat receiving part 412, and the left auxiliary heat receiving part 412 is located below the left liquid receiving tray 15. And / or, the right liquid receiving tray 16 is provided with a right through hole 161, and the right heat collector 42 includes a right main heat receiving part 421 that can pass through the right through hole 161 to directly absorb the heat of the right burner head 12, and a right auxiliary heat receiving part 422 that can contact the right liquid receiving tray 16 to indirectly absorb the heat of the right burner head 12 through the right liquid receiving tray 16; specifically, the right heat collector 42 is connected to the right liquid receiving tray 16 through the right auxiliary heat receiving part 422, and the right auxiliary heat receiving part 422 is located below the right liquid receiving tray 16.

[0207] In this embodiment, taking the left heat collector 41 as an example, its left main heating part 411 can directly absorb the heat generated when the left burner 11 is working through thermal radiation. At the same time, its left auxiliary heating part 412 is connected to the left liquid receiving pan 15 and can absorb the heat of the left liquid receiving pan 15 through heat transfer. The superposition of heat from multiple sources makes the left heat collector 41 achieve a better waste heat absorption effect. Taking the right heat collector 42 as an example, its right main heating part 421 can directly absorb the heat generated when the right burner 12 is working through thermal radiation. At the same time, its right auxiliary heating part 422 is connected to the right liquid receiving pan 16 and can absorb the heat of the right liquid receiving pan 16 through heat transfer. The superposition of heat from multiple sources makes the right heat collector 42 achieve a better waste heat absorption effect.

[0208] In one specific embodiment, the left auxiliary heating part 412 includes a left flange, which is connected to and fits against the lower surface of the left liquid receiving tray 15 via a connector, and / or, the right auxiliary heating part 422 includes a right flange, which is connected to and fits against the lower surface of the left liquid receiving tray 15 via a connector.

[0209] In this embodiment, the left auxiliary heating portion 412 may include a left flange, the extension direction of which may be consistent with the extension direction of the lower surface of the left liquid receiving tray 15, so that the left flange and the lower surface of the left liquid receiving tray 15 can fit together well; after the two are fitted together, they can be connected by providing a connector. For example, when the connector is in the form of a screw, openings for installing the connector can be provided on the left flange and the left liquid receiving tray 15.

[0210] The right auxiliary heating portion 422 may include a right flange, the extension direction of which may be consistent with the extension direction of the lower surface of the right liquid receiving tray 16, so that the right flange and the lower surface of the right liquid receiving tray 16 can fit well together; after the two are fitted together, they can be connected by a connector. For example, when the connector is in the form of a screw, openings for installing the connector can be provided on the right flange and the right liquid receiving tray 16.

[0211] In one embodiment, the left main heating section 411 and the left burner head 11 are concentrically arranged, and the central angle of the left main heating section is an acute angle; and / or, the right main heating section 421 and the right burner head 12 are concentrically arranged, and the central angle of the right main heating section is an acute angle.

[0212] In this embodiment, the left main heating element 411 can be concentrically arranged with the left burner head 11, which facilitates the uniform absorption of heat from the left burner head 11 and also ensures that the left main heating element 411 is compatible with the installation position, avoiding interference and other problems. Similarly, the right main heating element 421 can also be concentrically arranged with the right burner head 12.

[0213] Specifically, taking the left main heating part 411 as an example, the central angle of the left main heating part is an acute angle, the projection of the left main heating part 411 toward the left liquid receiving plate 15 is fan-shaped, and the central angle of the left main heating part 411 is 20° to 60°.

[0214] When the left main heating element 411 is fan-shaped, the central angle of the fan is not less than 20° to ensure that the left main heating element 411 has sufficient heating area to absorb the heat from the left burner head 11; in addition, the central angle of the fan is not greater than 60°, so that the left main heating element 411 will not cause excessive obstruction, ensuring sufficient oxygen and complete combustion when the left burner head 11 is burning. Of course,

[0215] Of course, it is not excluded that the central angle of the left main heating part 411 may slightly exceed the above-mentioned range in the embodiments of this application. When the central angle of the left main heating part 411 slightly exceeds the above-mentioned numerical range, it may still achieve the same effect as the above-mentioned boundary value.

[0216] The central angle of the right main heating element 421 is acute, and the projection of the right main heating element 421 toward the right liquid receiving plate 16 is fan-shaped. The central angle of the right main heating element 421 is between 20° and 60°. The preferred setting of the specific central angle of the right main heating element 421 can be referred to the description of the central angle of the left main heating element 411 above, and will not be repeated here.

In this embodiment, the left burner 11 and right burner 12 of the stove are symmetrically arranged about this center line (perpendicular bisector EE).

[0218] The left burner head 11 has a left inner gas outlet and a left outer gas outlet. The left inner gas outlet is equipped with a left inner flame cover, and the left outer gas outlet is equipped with a left outer flame cover.
