[0038] This embodiment provides a gas stove. To adapt to the user's usage scenario, gas or primary air is introduced as a stable and continuous cold source in the thermoelectric power generation component, and the component irradiated by high temperature is used as a heat source to form continuous and stable thermoelectric power generation.
[0039] As Figure 1 shown, the gas stove includes a stove top 1, a thermoelectric power generation component, a gas system 9 and a stove component 10. Among them, the thermoelectric power generation component is used to supply power to the stove electronic control system. It includes a thermoelectric chip and a heat dissipation component. The thermoelectric chip has a hot end and a cold end. The hot end of the thermoelectric chip is connected to the high temperature component of the gas stove, and the cold end of the thermoelectric chip is attached to the heat dissipation component. There is continuous gas or primary air passing through the heat dissipation component. The thermoelectric power generation component is electrically connected to the stove electronic control system.
[0040] This thermoelectric power generation component uses gas or primary air as a cold source to keep the heat dissipation component within a lower temperature range, so as to ensure that the temperature difference between the hot end and the cold end of the thermoelectric chip is continuously maintained within a certain range, and thus ensure continuous power generation; in addition, after the gas exchanges heat with the heat dissipation component, a preheating effect is achieved, the temperature of the gas entering the burner 5 is increased, the energy of the gas molecules is more active, and thus the combustion is more complete, improving the combustion efficiency.
[0041] In this embodiment, as Figures 1 to 3As shown, the cooking appliance panel 1 is a high-temperature component. The thermopile includes a first thermopile 2, and the hot end of the first thermopile 2 is attached to the back of the cooking appliance panel 1. The cooking appliance panel 1 is subjected to high-temperature radiation and has a very high temperature. Therefore, the cooking appliance panel 1 can serve as the heat source of the thermoelectric power generation component. The heat sink includes a first heat sink 3, and the cold end of the first thermopile 2 is attached to the first heat sink 3. There is continuous gas passing through the inside of the first heat sink 3. When the low-temperature gas passes through the first heat sink 3, it exchanges heat with the first heat sink 3 and takes away the heat of the first heat sink 3, keeping the first heat sink 3 within a relatively low temperature range. Therefore, the first heat sink 3 can serve as the cold source of the thermoelectric power generation component.
[0042] The cooking appliance panel 1 has a high-temperature area H, and the hot end of the first thermopile 2 is attached to and covers the high-temperature area H on the back of the cooking appliance panel 1, so that the hot end of the first thermopile 2 is continuously and stably within a certain temperature range.
[0043] Further, as Figures 2 to 4 shown, the gas stove further includes a heat equalizing part 4. The heat equalizing part 4 is attached to and covers the high-temperature area H on the back of the cooking appliance panel 1, making the temperature of the heat equalizing part 4 close to that of the cooking appliance panel 1. Thus, it can serve as the heat source for thermoelectric power generation, and the hot end of the first thermopile 2 is attached to the back of the heat equalizing part 4. The heat equalizing part 4 can make the temperature within the high-temperature area H close, reduce the problem of local high temperature, prevent the cooking appliance panel 1 from bursting due to stress concentration caused by local overheating, and thus extend the service life of the cooking appliance panel 1.
[0044] Optionally, the heat equalizing part 4 is an aluminum plate. Of course, the heat equalizing part 4 can also be other metal plates with excellent thermal conductivity, which are not listed one by one here.
[0045] As Figure 5 shown, the gas system 9 includes an air inlet joint 91, an aluminum pipe 92, a valve body 93, and an air inlet pipe 94. When the gas stove is ignited and working, gas enters from the air inlet joint 91, passes through the first heat sink 3 and then enters the air inlet pipe 94, and then flows into the corresponding burner 5 in sequence through the corresponding valve body 93 and aluminum pipe 92 for combustion. It should be noted that the number of burners 5 is not limited in this embodiment, and it can be one, two, or multiple. In this embodiment, as Figure 1 shown, two burners 5 are provided on the cooking appliance.
[0046] As Figure 6 and Figure 7As shown in the figure, the first heat dissipation member 3 in this embodiment includes a first substrate 31. The top of the first substrate 31 is attached to the first thermoelectric sheet 2. A gas passage is provided on the first substrate 31, and a plurality of first heat dissipation fins 32 are provided in the gas passage. The plurality of first heat dissipation fins 32 are distributed in a central radiation manner. When the gas passes through the first heat dissipation member 3, heat exchange occurs between the gas and the first heat dissipation fins 32, reducing the temperature of the first heat dissipation member 3 itself, ensuring the stability of the temperature difference between the cold end and the hot end of the first thermoelectric sheet 2, and thus continuously generating electricity. At the same time, it can also increase the temperature of the gas entering the burner 5, realizing preheating of the gas, making the gas molecules more active in energy and burning more fully, thereby improving the combustion efficiency of the combustion. An air passage is also provided on the first substrate 31, and a plurality of second heat dissipation fins 33 are provided at intervals in the air passage. The second heat dissipation fins 33 are connected to the bottom of the first substrate 31, and the second heat dissipation fins 33 can exchange heat with the air inside the gas stove, thereby reducing the temperature of the first heat dissipation member 3 itself. The plurality of second heat dissipation fins 33 are vertically downward and arranged in parallel. This structural setting can increase the surface area of the first heat dissipation member 3, thereby improving the heat dissipation effect of the first heat dissipation member 3.
[0047] As Figure 8 and Figure 9 shown in the figure, the stove assembly 10 in this embodiment includes a burner 5. The burner head of the burner 5 can also be used as a high-temperature component. The thermoelectric sheet includes a second thermoelectric sheet 6. The hot end of the second thermoelectric sheet 6 is connected to the burner head. The heat dissipation member includes a second heat dissipation member 7. The cold end of the second thermoelectric sheet 6 is attached to the second heat dissipation member 7. There is continuous primary air passing through the inside of the second heat dissipation member 7. When the primary air passes through the second heat dissipation member 7, heat exchange occurs with the second heat dissipation member 7, taking away the heat of the second heat dissipation member 7 and keeping the second heat dissipation member 7 within a lower temperature range. Therefore, the second heat dissipation member 7 can be used as a cold source for thermoelectric power generation. The flow direction of the primary air is as Figure 10 shown by a in the figure.
[0048] The burner 5 further includes a fixing seat 8. The fixing seat 8 is connected to the burner head and can conduct heat exchange. The hot end of the second thermoelectric sheet 6 is attached to the fixing seat 8. The heat of the burner head is transferred to the fixing seat 8, and the fixing seat 8 can be used as a stable heat source for the second thermoelectric sheet 6.
[0049] Continue to refer to Figure 9As shown, the second heat sink 7 includes a second substrate 71 and a plurality of third heat dissipation fins 72 arranged at intervals. The second substrate 71 is attached to the second thermoelectric sheet 6, and the third heat dissipation fins 72 are connected to the bottom of the second substrate 71. One end of the third heat dissipation fin 72 in the length direction extends to the air inlet of the ejector tube of the burner 5. This structural arrangement can increase the surface area of the second heat sink 7. The primary air contacts and exchanges heat with the third heat dissipation fins 72, continuously taking away the heat of the third heat dissipation fins 72, so that the second heat sink 7 is maintained within a lower temperature range, thereby ensuring that the temperature difference between the hot end and the cold end of the second thermoelectric sheet 6 is continuously maintained within a certain range, and further ensuring continuous power generation. At the same time, the primary air is heated after passing through the second heat sink 7 and then enters the ejector tube, which can improve the thermal efficiency of the burner 5. Further, one end of the third heat dissipation fin 72 in the length direction extends beyond the air inlet of the ejector tube, which can increase the contact area between the primary air and the second heat sink 7, so that the primary air can be fully preheated by the second heat sink 7, further improving the thermal efficiency of the burner 5.
