Description

Technical Field

[0001] The invention relates to the technical field of kitchen appliances, and in particular to a panel and a gas stove having the panel. Background Art

[0002] Energy is the material basis of human activities. With the development of society, the energy crisis is becoming increasingly serious. Nowadays, in order to improve people's living standards and enable sustainable development of human life, more and more new energy sources are being developed and utilized in our real lives. At present, gas stoves are still powered by dry batteries or city electricity. In order to reduce energy waste, we also need to find new energy sources to replace dry batteries and city electricity to power gas stoves.

[0003] As for the new energy sources for powering gas stoves, solar energy is currently more widely used for power generation. The prior art discloses a solar stove that replaces the gas stove, collects solar energy, and uses solar energy for cooking and boiling water. In order to collect more sunlight, the application site of the solar stove is generally outdoors. If it is set indoors, it will not be able to make good use of solar energy due to the limitation of indoor space. In order to overcome the problem of limited space, the prior art also discloses a solar ignition device for gas stoves, which installs a solar cell module on the gas stove panel to convert weak light such as ambient light (such as sunlight, lamplight, and lighting light of a range hood) or strong light such as flame light into electrical energy as the power source for ignition. However, this design directly sets the solar panel on the gas stove panel. The temperature of the panel is often high when the gas stove is working. High temperature will reduce the photoelectric conversion efficiency. Therefore, the solar panel has the problem that the photoelectric conversion efficiency decreases as the temperature increases, resulting in poor final power generation effect. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect of low conversion efficiency of gas stoves in the prior art when converting light energy into electrical energy, thereby providing a panel with high conversion efficiency when converting light energy into electrical energy and a gas stove having the same.

[0011] The heat insulation support plates are distributed around the edges of the first light-transmitting plate and the second light-transmitting plate.

[0012] The light-transmitting and heat-insulating layer is a vacuum layer.

[0013] The first light-transmitting plate is made of heat-conducting material.

[0014] The panel also includes a hot end of a thermoelectric power generation element, which is connected between the thermal insulation support plate and the first light-transmitting plate and is suitable for absorbing heat conducted by the first light-transmitting plate. The hot end of the thermoelectric power generation element is suitable for being connected to the power storage device and is suitable for cooperating with the cold end of the thermoelectric power generation element on the application object to generate an electromotive force to form a thermoelectric power generation current stored in the power storage device.

[0015] A gas stove comprises the panel as described above, and the application object is the gas stove.

[0016] It also includes a bottom shell, on which a cold end assembly of a temperature difference power generation element is arranged.

[0017] The cold end assembly of the temperature difference power generation element is arranged adjacent to the heat dissipation groove on the bottom shell.

[0018] The cold end assembly of the thermoelectric power generation element includes a cold end of the thermoelectric power generation element and a heat sink, wherein the heat sink is arranged below the cold end of the thermoelectric power generation element.

[0019] The power storage device is connected to the igniter of the gas stove.

[0020] The technical solution of the present invention has the following advantages:

[0021] 1. A panel provided by the present invention comprises: a first light-transmitting plate; a solar panel, arranged below the first light-transmitting plate and suitable for connection with the power storage device; a light-transmitting heat-insulating layer, arranged between the first light-transmitting plate and the solar panel, suitable for isolating the transfer of heat from the first light-transmitting plate to the solar panel. By providing the first light-transmitting plate, light can be transferred to the solar panel through the first light-transmitting plate, and the solar panel converts light energy into electrical energy and stores it in the power storage device. By providing the light-transmitting heat-insulating layer, the transfer of heat to the solar panel is isolated, so that in the process of light-heat transfer, only light energy is transferred to the solar panel through the first light-transmitting plate, and high temperature will not be conducted to the solar panel, thereby avoiding the influence of high temperature on the photoelectric conversion of the solar panel, ensuring the conversion of light energy into electrical energy while improving the photoelectric conversion efficiency.

[0022] 2. In a panel provided by the present invention, the light-transmitting and heat-insulating layer is a vacuum layer. By setting the light-transmitting and heat-insulating layer as a vacuum layer and directly evacuating the light-transmitting and heat-insulating layer, the light-transmitting and heat-insulating function can be achieved without separately setting other light-transmitting and heat-insulating components, so that the structure of the panel is simpler and the light-transmitting and heat-insulating effect is better.

[0023] 3. A panel provided by the present invention further includes a second light-transmitting plate, which is arranged on the upper surface of the solar panel, and the light-transmitting and heat-insulating layer is arranged between the first light-transmitting plate and the second light-transmitting plate. By arranging the second light-transmitting plate and the light-transmitting and heat-insulating layer between the first light-transmitting plate and the second light-transmitting plate, the strength requirements on both sides of the vacuum layer are guaranteed, and it is prevented that the solar panel is directly vacuumed, which may damage the solar panel and affect the effect of light energy power generation.

[0024] 4. A panel provided by the present invention further includes a heat-insulating support plate, one end of which is connected to the first light-transmitting plate, and the other end of which is connected to the second light-transmitting plate, and is suitable for supporting the first light-transmitting plate and the second light-transmitting plate to form the light-transmitting heat-insulating layer. By providing a heat-insulating support plate to support the light-transmitting heat-insulating layer, heat isolation is ensured while making the overall structure of the panel more compact.

[0025] 5. In a panel provided by the present invention, the first light-transmitting plate is made of a heat-conducting material. By setting the first light-transmitting plate to be a heat-conducting material, the transmission of light to the solar panel is ensured, and the application of heat is facilitated.

[0026] 6. The present invention provides a panel, the panel also includes a hot end of a thermoelectric power generation element, the hot end of the thermoelectric power generation element is connected between the heat-insulating support plate and the first light-transmitting plate, and is suitable for absorbing the heat conducted by the first light-transmitting plate. The hot end of the thermoelectric power generation element is suitable for being connected to the power storage device, and is suitable for cooperating with the cold end of the thermoelectric power generation element on the application object to generate an electromotive force to form a thermoelectric power generation current stored in the power storage device. By arranging the hot end of the thermoelectric power generation element between the heat-insulating support plate and the first light-transmitting plate, the heat is directly conducted to the hot end of the thermoelectric power generation element through the first light-transmitting plate, and then cooperates with the cold end of the thermoelectric power generation element to generate electricity using the temperature difference of the heat, so that the panel can realize both the conversion of light energy into electrical energy and the conversion of temperature difference into electrical energy, and can absorb and utilize both light and heat energy at the same time, thereby improving the utilization rate of energy.

[0027] 7. In a gas stove provided by the present invention, the cold end assembly of the thermoelectric power generation element is arranged adjacent to the heat dissipation groove on the bottom shell. The heat dissipation groove on the bottom shell of the gas stove is the place where the inside of the gas stove contacts the outside air. When the gas stove is working, the air flow speed at the heat dissipation groove is faster. The faster air flow speed is conducive to heat dissipation. During the thermoelectric power generation process, the temperature of the cold end of the thermoelectric power generation element will increase. Placing the cold end assembly of the thermoelectric power generation element next to the heat dissipation groove can ensure that the cold end of the thermoelectric power generation element is at a sufficiently low temperature, thereby improving the efficiency of thermoelectric power generation.

[0028] 8. In a gas stove provided by the present invention, the cold end assembly of the thermoelectric power generation element comprises a cold end of the thermoelectric power generation element and a heat sink, and the heat sink is arranged below the cold end of the thermoelectric power generation element. By arranging the heat sink below the cold end of the thermoelectric power generation element, the heat dissipation area of ​​the cold end is expanded, the temperature of the cold end is further lowered, and the efficiency of thermoelectric power generation is improved.

DETAILED DESCRIPTION

[0037] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] like Figure 1-Figure 5 As shown, in this embodiment, a panel is provided, which is suitable for being arranged on a gas stove. The gas stove is provided with a power storage device 02 , and the panel 01 includes: a first light-transmitting plate 1 , a solar panel 4 and a light-transmitting heat-insulating layer 5 .

[0040] like Figure 2 As shown, the solar panel 4 in this embodiment is a solar power generation panel, which is arranged below the first light-transmitting plate 1 and is suitable for connecting to the power storage device 02; the light-transmitting heat-insulating layer 5 is arranged between the first light-transmitting plate 1 and the solar panel 4, and is suitable for isolating the transfer of heat from the first light-transmitting plate 1 to the solar panel 4.

[0041] By setting the first light-transmitting plate 1, light can be transmitted through the first light-transmitting plate 1 to the solar panel 4, and the solar panel 4 converts light energy into electrical energy and stores it in the power storage device 02. By setting the light-transmitting heat-insulating layer 5, the transfer of heat to the solar panel 4 is isolated, so that in the process of light and heat transfer, only light energy is transmitted to the solar panel 4 through the first light-transmitting plate 1, and high temperature will not be conducted to the solar panel 4, thereby avoiding the influence of high temperature on the photoelectric conversion of the solar panel 4, ensuring the conversion of light energy into electrical energy while improving the photoelectric conversion efficiency.

[0042] As a convertible implementation, the panel 01 may also be arranged on other application objects that need to generate electricity, such as a solar cooker or other equipment that needs to generate electricity through heat insulation.

[0043] As a convertible implementation, the solar panel 4 may also be a photovoltaic panel.

[0044] The light-transmitting heat-insulating layer 5 in this embodiment is a vacuum layer. By setting the light-transmitting heat-insulating layer 5 as a vacuum layer and directly evacuating the light-transmitting heat-insulating layer 5, the light-transmitting heat-insulating function can be achieved without separately setting other light-transmitting heat-insulating components, making the structure of the panel 01 simpler and having a better light-transmitting heat-insulating effect.

[0045] As a convertible implementation, the light-transmitting heat-insulating layer 5 may also be a heat-insulating glass, which can both ensure the transmission of light to the solar panel 4 and isolate the conduction of heat to the solar panel 4 .

[0046] The panel 01 in this embodiment further includes a second light-transmitting plate 3, which is disposed on the upper surface of the solar panel 4, and a light-transmitting and heat-insulating layer 5 is disposed between the first light-transmitting plate 1 and the second light-transmitting plate 3. By disposing the second light-transmitting plate 3 and the light-transmitting and heat-insulating layer 5 between the first light-transmitting plate 1 and the second light-transmitting plate 3, the strength requirements on both sides of the vacuum layer are ensured, and it is prevented that the solar panel 4 is directly vacuumed, which may damage the solar panel 4 and affect the light energy power generation effect.

[0047] The panel 01 in this embodiment further includes a heat-insulating support plate 2, one end of which is connected to the first light-transmitting plate 1, and the other end of which is connected to the second light-transmitting plate 3, and is suitable for supporting the first light-transmitting plate 1 and the second light-transmitting plate 3 to form a light-transmitting heat-insulating layer 5. Specifically, the heat-insulating support plate 2 in this embodiment is distributed around the edge of the first light-transmitting plate 1 and the second light-transmitting plate 3, so that the middle part between the first light-transmitting plate 1 and the second light-transmitting plate 3 is evacuated to form a vacuum layer. By providing the heat-insulating support plate 2 to support the light-transmitting heat-insulating layer 5, the overall structure of the panel 01 is made more compact while ensuring heat isolation.

[0048] As a convertible embodiment, the heat insulating support plate 2 and the light-transmitting heat insulating layer 5 may both be formed by a heat insulating glass plate.

[0049] Specifically, the first light-transmitting plate 1 in this embodiment is made of a heat-conducting material. By setting the first light-transmitting plate 1 as a heat-conducting material, the transmission of light to the solar panel 4 is guaranteed, and the application of heat is convenient. The second light-transmitting plate 3 in this embodiment is made of a heat-insulating material, which can further isolate the conduction of heat to the solar panel 4.

[0050] The panel 01 in this embodiment also includes a hot end 6 of a thermoelectric power generation element, which is connected between the heat-insulating support plate 2 and the first light-transmitting plate 1 and is suitable for absorbing the heat conducted by the first light-transmitting plate 1. The hot end 6 of the thermoelectric power generation element is suitable for being connected to the power storage device 02, and is suitable for cooperating with the cold end 7 of the thermoelectric power generation element on the gas stove to generate an electromotive force, forming a thermoelectric power generation current stored in the power storage device 02. Specifically, the hot end 6 of the thermoelectric power generation element in this embodiment is connected to the positive electrode of the power storage device 02, and the cold end 7 of the thermoelectric power generation element is connected to the negative electrode of the power storage device 02. By arranging the hot end 6 of the thermoelectric power generation element between the heat-insulating support plate 2 and the first light-transmitting plate 1, the heat is directly conducted to the hot end 6 of the thermoelectric power generation element through the first light-transmitting plate 1, and then cooperates with the cold end 7 of the thermoelectric power generation element to generate electricity using the temperature difference of the heat, so that the panel 01 can realize both the conversion of light energy into electrical energy and the conversion of temperature difference into electrical energy, and can absorb and utilize both light and heat energy at the same time, thereby improving the utilization rate of energy. As an alternative embodiment, the cold end 7 of the thermoelectric power generation element may be connected to the positive electrode of the power storage device 02 , and the hot end 6 of the thermoelectric power generation element may be connected to the negative electrode of the power storage device 02 .

[0051] Specifically, the thermoelectric power generation element in this embodiment is a metal body. As an alternative embodiment, the thermoelectric power generation element may be a semiconductor.

[0052] Specifically, in this embodiment, the first light-transmitting plate 1, the heat-insulating support plate 2, the second light-transmitting plate 3 and the solar panel 4 are bonded together, and the hot end 6 of the temperature difference power generation element is also bonded together with the heat-insulating support plate 2 and the first light-transmitting plate 1. As a convertible embodiment, the components can also be connected by riveting.

[0053] like Figure 5 As shown, a gas stove is also provided in this embodiment, including the above-mentioned panel 01. The above-mentioned panel 01 can simultaneously utilize light energy and temperature difference to generate electricity, store the electric energy in the power storage device 02, and provide electric energy for the igniter of the gas stove, etc., so that the energy utilization rate is high. Specifically, the input current of the gas stove in this embodiment is direct current. As a convertible implementation method, it can also be that the gas stove is equipped with a controller, and its input current is alternating current, and an inverter can be added after the power storage device 02 to provide power for the gas stove.

[0054] The gas stove in this embodiment also includes a bottom shell 03, on which a cold end assembly 05 of a thermoelectric power generation element is arranged. Specifically, the cold end assembly 05 of the thermoelectric power generation element in this embodiment is arranged adjacent to the heat dissipation slot 04 on the bottom shell 03. The heat dissipation slot 04 on the bottom shell 03 of the gas stove is where the inside of the gas stove contacts the outside air. When the gas stove is working, the air flow speed at the heat dissipation slot 04 is faster, and the faster air flow speed is conducive to heat dissipation. During the thermoelectric power generation process, the temperature of the cold end of the thermoelectric power generation element will increase. Placing the cold end assembly 05 of the thermoelectric power generation element next to the heat dissipation slot 04 can ensure that the cold end of the thermoelectric power generation element is at a sufficiently low temperature, thereby improving the efficiency of thermoelectric power generation.

[0055] like Figure 4 As shown, the cold end assembly 05 of the thermoelectric power generation element in this embodiment includes the cold end 7 of the thermoelectric power generation element and the heat sink 8, and the heat sink 8 is arranged below the cold end 7 of the thermoelectric power generation element. By arranging the heat sink 8 below the cold end 7 of the thermoelectric power generation element, the heat dissipation area of ​​the cold end is expanded, the temperature of the cold end is further lowered, and the efficiency of thermoelectric power generation is improved.

[0056] The power storage device 02 in this embodiment is connected to the igniter of the gas stove, and the power storage device 02 directly supplies power to the pulse igniter. There are many forms of the power storage device 02. Specifically, the power storage device 02 in this embodiment is a battery. As a convertible implementation, the power storage device 02 can also be a battery pack or a rechargeable battery. As a convertible implementation, the power storage device 02 can also be used as an electric energy storage device to store electric energy and use it when needed.

[0057] When the gas stove is not in working condition, various lights in the kitchen, such as sunlight, lamplight, and lighting from a range hood, can pass through the first light-transmitting plate 1 and the second light-transmitting plate 3 to the solar panel 4, converting light energy into electrical energy and then storing it in the power storage device 02; when the gas stove is in working condition, various lights in the kitchen, such as sunlight, lamplight, lighting from a range hood, and flame light from a burning flame, can pass through the first light-transmitting plate 1 and the second light-transmitting plate 3 to the solar panel 4, converting light energy into electrical energy and then storing it in the power storage device 02. Due to the existence of the vacuum layer, the heat generated during the combustion process will not be transferred to the solar panel 4, avoiding the influence of temperature on the photoelectric conversion efficiency of the solar panel 4, and the residual heat generated during the combustion process will be transferred to the hot end 6 of the thermoelectric power generation element through the heat conduction of the first light-transmitting plate 1, and the cold end 7 of the thermoelectric power generation element is connected to the heat sink 8 and placed next to the heat dissipation groove 04 of the bottom shell 03, which can ensure that the temperature of the cold end 7 of the thermoelectric power generation element is low enough. Under the action of the Seebeck effect, an electromotive force will be generated between the hot end 6 of the thermoelectric power generation element and the cold end 7 of the thermoelectric power generation element to form a thermoelectric power generation current, and then the electric energy generated by the thermoelectric power generation is stored in the power storage device 02, and the pulse igniter of the gas stove will be powered when needed.

[0058] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
