[0010] Beneficial effects: Since the hot end of the thermoelectric power generation structure is connected to the heat collection structure and the cold end is connected to the cooling box, the heat collection structure can absorb the heat generated by the combustion of the gas, so the temperature is relatively high. The cooling box is suitable for the gas to pass through and the temperature is relatively low. The temperature difference between the hot end and the cold end can be used for power generation. Since the gas flowing out of the cooling box is sent to the burner for combustion, the temperature of the gas flowing out of the cooling box increases, which can improve the thermal efficiency of the gas stove.

Also, it is relatively close to the flame of the burner, so the temperature of the energy concentrating plate itself is relatively high (measured to reach 170 - 200 °C). The hot end of the thermoelectric generation structure is attached to the energy concentrating plate, enabling it to obtain a large amount of heat energy, making the temperature of the hot end of the thermoelectric generation structure higher, increasing the temperature difference between the cold end and the hot end, and thus improving the power generation efficiency.

Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0052] Gas stoves usually use mains electricity or dry batteries to supply electrical energy to control systems such as electric igniters and flameout protection devices. Using mains electricity can easily make the structure of the gas stove complex, while using dry batteries requires frequent replacement, resulting in poor usability and easy environmental pollution.

[0053] Related technologies have disclosed a gas stove device, including a stove top; a burner head, which is arranged on the stove top, and the burner head includes a furnace body and a pot support integrally connected to the furnace body; a heat collection and power generation device, which is arranged on the stove top, and the hot end of the heat collection and power generation device is in abutting contact with the furnace body; a heat dissipation device, which is in abutting contact with the cold end of the heat collection and power generation device. Among them, the heat dissipation device mainly consists of a water cooling plate, a water storage tank and a pump body. The pump body can be a micro water pump. The water cooling plate is in direct contact with the cold end of the heat collection and power generation device. The water storage tank is connected to the water cooling plate through the pump body, and the top of the water storage tank is connected to the bottom of the stove top, so as to be installed at the bottom of the stove top. In this related technology, the heat dissipation device includes a water storage tank, and cold water needs to be provided for the water storage tank, resulting in a complex structure of the gas stove device.

[0054] Related technologies have also disclosed a gas stove waste heat utilization and energy saving integrated device, including an annular energy collecting plate, a water cooling device and a power generation device arranged on the energy collecting plate. This related technology cools the cold end of the power generation device through the water cooling device, which also results in a complex structure of the gas stove.

[0055] The following combines Figures 1 to 11 , to describe the embodiments of the present invention.

[0056] According to an embodiment of the present invention, a gas stove is provided, including a heat collection structure, a cooling box 1 and a thermoelectric power generation structure 2.

[0057] Among them, the heat collection structure can absorb the heat generated by gas combustion; the cooling box 1 is suitable for gas to pass through, and the gas flowing out of the cooling box 1 is sent to the burner head 9 for combustion; the thermoelectric power generation structure 2, its hot end is connected to the heat collection structure, and its cold end is connected to the cooling box 1.

[0058] In this embodiment, since the hot end of the thermoelectric power generation structure 2 is connected to the heat collection structure and the cold end is connected to the cooling box 1, and the heat collection structure can absorb the heat generated by gas combustion, so the temperature is relatively high, and the cooling box 1 is suitable for gas to pass through and the temperature is relatively low. The temperature difference between the hot end and the cold end can be used for power generation. Since the gas flowing out of the cooling box 1 is sent to the burner head 9 for combustion, the temperature of the gas flowing out of the cooling box 1 increases, which can improve the thermal efficiency of the gas stove. Since the gas is used to dissipate heat and cool the cold end of the thermoelectric power generation structure 2, compared with the related technology, the structure is simpler and more convenient for users to use.

[0059] Specifically, in one embodiment, the gas stove includes a total of two burners 9, and two or more thermoelectric power generation structures 2 can be provided. The cold ends of multiple thermoelectric power generation structures 2 can be cooled by the same cooling box 1.

[0060] Specifically, in one embodiment, two thermoelectric power generation structures 2 are symmetrically provided, and the cold ends of the two thermoelectric power generation structures 2 are both cooled by the cooling box 1.

[0061] In one embodiment, heat dissipation fins 3 are provided in the cooling box 1, and a heat conduction tube 4 is connected to the cold end. The heat conduction tube 4 extends into the cooling box 1 and is connected to the heat dissipation fins 3.

[0062] In this embodiment, by providing heat dissipation fins 3 in the cooling box 1 and connecting the cold end of the thermoelectric power generation structure 2 to the heat dissipation fins 3 through the heat conduction tube 4, the heat dissipation and cooling efficiency of the cold end of the thermoelectric power generation structure 2 can be improved.

[0063] Specifically, in one embodiment, two or more heat conduction tubes 4 can be connected to the cold end of each thermoelectric power generation structure 2, and the two or more heat conduction tubes 4 are all connected to the heat dissipation fins 3, which can further improve the heat dissipation and cooling efficiency of the cold end of the thermoelectric power generation structure 2.

[0064] Specifically, as Figure 1 shown, multiple heat conduction tubes 4 are connected to the cold end of each thermoelectric power generation structure 2.

[0065] In one embodiment, multiple heat dissipation fins 3 are provided, and the heat conduction tubes 4 penetrate through multiple heat dissipation fins 3.

[0066] In this embodiment, multiple heat dissipation fins 3 are provided and the heat conduction tubes 4 penetrate through multiple heat dissipation fins 3. Therefore, each heat conduction tube 4 dissipates heat through multiple heat dissipation fins 3, which can further improve the heat dissipation and cooling efficiency of the cold end of the thermoelectric power generation structure 2.

[0067] Specifically, as Figure 2 shown, the length extension direction of the heat dissipation fins 3 is the same as the gas flow direction, and the gas can flow through the space between two adjacent heat dissipation fins 3. The length extension direction of the heat conduction tube 4 in the cooling box 1 is perpendicular to the gas flow direction.

[0068] In one embodiment, a flow guiding structure is provided in the cooling box 1, and the flow guiding structure is used to guide the gas entering the cooling box 1 to flow towards the heat dissipation fins 3.

[0069] In this embodiment, by providing a flow guiding structure in the cooling box 1, the flow guiding structure can guide the gas entering the cooling box 1 to flow towards the heat dissipation fins 3, enabling the gas flow to just blow onto the heat dissipation fins 3, further improving the heat dissipation and cooling efficiency of the cold end of the thermoelectric power generation structure 2 and making the cold end temperature of the thermoelectric power generation structure 2 lower.

[0070] In one embodiment, a gas inlet is provided on the first sidewall 101 of the cooling box 1. The flow guiding structure includes a baffle 5. The baffle 5 faces the first sidewall 101 and extends towards both sides of the cooling box 1. A plurality of openings 501 are provided on the baffle 5, and the openings 501 face the heat sink 3.

[0071] In this embodiment, the flow guiding structure includes a baffle 5. The baffle 5 faces the first sidewall 101 and extends towards both sides of the cooling box 1. When the gas flow enters the cooling box 1 from the gas inlet, blocked by the baffle 5, it cannot flow directly in the direction facing the gas inlet, but can only flow towards both sides, and then flows from the openings 501 to the heat sink 3, improving the heat dissipation and cooling efficiency of the cold end of the thermoelectric generation structure 2 and making the temperature of the cold end of the thermoelectric generation structure 2 lower.

[0072] Specifically, as Figure 1 and Figure 2 shown, both ends of the baffle 5 abut against two opposite sidewalls of the cooling box 1. After the gas enters from the gas inlet, it first enters the space between the baffle 5 and the first sidewall 101. Since the rest of the baffle 5 is closed, it can only flow from the openings 501 to the heat sink 3, improving the heat dissipation and cooling efficiency of the cold end of the thermoelectric generation structure 2 and making the temperature of the cold end of the thermoelectric generation structure 2 lower.

[0073] In an embodiment not shown in the figure, both ends of the baffle 5 may not abut against two opposite sidewalls of the cooling box 1, but there may be gaps.

[0074] In an embodiment not shown in the figure, the flow guiding structure may include a plurality of flow guiding plates, and the flow guiding plates guide the gas flow to the heat sink 3.

[0075] The flow guiding plate may specifically be a straight plate shape or a curved plate 7.

[0076] Specifically, in one embodiment, a gas outlet is provided on the second sidewall 102 of the cooling box 1. The second sidewall 102 is opposite to the first sidewall 101. The gas inlet is connected to the first gas pipeline 10, and the gas outlet is connected to the second gas pipeline 11. After flowing out from the second gas pipeline 11, it flows through the gas distribution pipe to different burners 9.

[0077] In one embodiment, the heat collecting structure includes a pot support 6. The pot support 6 surrounds the outside of the burner 9. The pot support 6 has an annular energy collecting disc 601. The energy collecting disc 601 has a predetermined angle with the horizontal plane, and the hot end is attached to the energy collecting disc 601.

[0078] In this embodiment, since the pot body bracket 6 has an annular energy-gathering disk 601, and the energy-gathering disk 601 has a predetermined angle with the horizontal plane, the heat generated by the gas combustion can be gathered inside it, increasing the contact time between the high-temperature flue gas and the pot body, and being relatively close to the flame of the burner. Therefore, the temperature of the energy-gathering disk 601 itself is relatively high (measured to reach 170 - 200 °C). The hot end of the thermoelectric power generation structure 2 is attached to the energy-gathering disk 601, enabling it to obtain a large amount of heat energy, making the hot end temperature of the thermoelectric power generation structure 2 higher, increasing the temperature difference between the cold end and the hot end, and thus improving the power generation efficiency.

[0079] In one embodiment, the energy-gathering disk 601 includes a planar portion 6011, and the hot end is attached to the planar portion 6011.

[0080] In this embodiment, the energy-gathering disk 601 includes a planar portion 6011, and the hot end is attached to the planar portion 6011, which can increase the contact area between the hot end of the thermoelectric power generation structure 2 and the energy-gathering disk 601, making the hot end temperature of the thermoelectric power generation structure 2 higher, increasing the temperature difference between the cold end and the hot end, and thus improving the power generation efficiency.

[0081] It should be noted that the thermoelectric power generation structure 2 is specifically a thermoelectric power generation chip. Therefore, the setting of the planar portion 6011 is beneficial to increasing the contact area between the hot end of the thermoelectric power generation chip and the energy-gathering disk 601.

[0082] In one embodiment, the length of the planar portion 6011 is greater than the length of the thermoelectric power generation structure 2, and / or the width of the planar portion 6011 is greater than the width of the thermoelectric power generation structure 2.

[0083] In this embodiment, by making the length of the planar portion 6011 greater than the length of the thermoelectric power generation structure 2, and / or the width of the planar portion 6011 greater than the width of the thermoelectric power generation structure 2, it can ensure that the entire hot end position of the thermoelectric power generation structure 2 is attached to the planar portion 6011, increasing the contact area between the hot end of the thermoelectric power generation structure 2 and the energy-gathering disk 601, making the hot end temperature of the thermoelectric power generation structure 2 higher, increasing the temperature difference between the cold end and the hot end, and thus improving the power generation efficiency.

[0084] Specifically, in one embodiment, the length of the planar portion 6011 is greater than the length of the thermoelectric power generation structure 2, and the width of the planar portion 6011 is greater than the width of the thermoelectric power generation structure 2.

[0085] In one embodiment, the energy-gathering disk 601 is provided with a plurality of fins 602.

[0086] In this embodiment, by providing a plurality of fins 602 on the energy-gathering disk 601, the energy-gathering disk 601 can absorb more heat energy, making the hot end temperature of the thermoelectric power generation structure 2 higher, increasing the temperature difference between the cold end and the hot end, and thus improving the power generation efficiency.

[0087] Specifically, in one embodiment, the fin 602 is in the shape of a sheet and has a thickness of 1-4 mm.

[0088] In one embodiment, the fin 602 is provided on the side of the flat portion 6011 opposite to the hot end.

[0089] In this embodiment, by providing the fin 602 on the side of the flat portion 6011 opposite to the hot end of the thermoelectric power generation structure 2, the energy collecting disc 601 can absorb more heat, making the temperature of the hot end of the thermoelectric power generation structure 2 higher, increasing the temperature difference between the cold end and the hot end, and thus improving the power generation efficiency.

[0090] Specifically, in one embodiment, the fin 602 is provided on the upper side of the flat portion 6011, and the thermoelectric power generation structure 2 is provided on the lower side of the flat portion 6011.

[0091] In one embodiment, notches or chamfers are provided at both ends of the fin 602.

[0092] In this embodiment, by providing notches or chamfers at both ends of the fin 602, it is possible to prevent the flame from directly burning the fin 602, which may cause excessive flue gas and uneven placement of the cookware.

[0093] Specifically, as Figure 10 shown, chamfers are provided at both ends of the fin 602.

[0094] In one embodiment, the pot body support 6 further includes a plurality of support portions 603 provided at intervals along the circumference on the energy collecting disc 601. The lower end of the support portion 603 abuts against the panel 7 or the liquid receiving tray, and the upper end of the support portion 603 is adapted to abut against the pot body.

[0095] In this embodiment, by providing a plurality of support portions 603, it is possible to facilitate the adjustment of the position of the pot, so that the cookware can stably contact the pot body support 6.

[0096] Specifically, as Figure 10 shown, the top end of the support portion 603 includes a horizontal portion and an inclined portion, which can be suitable for use with pots of different sizes.

[0097] It should be noted that the liquid receiving tray can be used to fix the panel 7 and the burner 9 to prevent the panel 7 from moving.

[0098] As Figure 3 shown, a knob 8 is provided on the panel 7, and the user can turn on the gas stove by rotating the knob 8 for use.

[0099] In one embodiment, the energy collecting disc 601 extends obliquely outward from bottom to top.

[0100] In this embodiment, the energy collecting disc 601 extends obliquely outward from bottom to top, which can increase the contact duration between the pot body and the flame.

[0101] In an embodiment not shown in the figure, the energy concentrating disc 601 may extend in the vertical direction.

[0102] For the gas stove provided in this embodiment, when the gas stove starts to work, the gas flow enters the cooling box 1 from the gas inlet, and then is guided by the baffle 5 in the cooling box 1. After that, the gas flow passes through the heat sink 3 to take away the heat transferred from the cold end of the thermoelectric generation structure 2 to the heat sink 3 through the heat conduction tube 4, and then enters the burner 9 for combustion. When the burner 9 is burning, the flame is surrounded by the energy concentrating disc 601. The energy concentrating disc 601 absorbs the flame radiation and convective heat exchange with the high-temperature flue gas, and the temperature rises. The hot end of the thermoelectric generation structure 2 is attached to the energy concentrating disc 601 and can absorb a large amount of heat, so as to form a large temperature difference with the cold end, and better power generation effect can be achieved. At the same time, during this process, the gas temperature becomes higher, which can accelerate the combustion reaction and improve the combustion efficiency.

[0103] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
