[0031] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following will, in conjunction with the accompanying drawings and embodiments, detail the implementation methods of the present invention, so as to fully understand how the present invention applies technical means to solve technical problems and the implementation process of achieving technical effects and implement accordingly.

[0032] Many specific details are set forth in the following description in order to provide a thorough understanding of the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0033] Aiming at the technical problem of the inconvenient use of existing gas stoves due to the frequent replacement of batteries, the embodiment of the present invention provides a self - powered gas stove. As Figure 1 shown, the self - powered gas stove described in this embodiment includes: a gas stove body, a thermoelectric power generation device, a photovoltaic conversion device, and an energy storage device; the thermoelectric power generation device and the photovoltaic conversion device are both disposed on the gas stove body; the thermoelectric power generation device and the photovoltaic conversion device are both electrically connected to the energy storage device; the thermoelectric power generation device is used to convert the heat energy generated by the gas stove body into electrical energy and transmit the electrical energy to the energy storage device for storage; the photovoltaic conversion device is used to convert light energy into electrical energy and transmit the electrical energy to the energy storage device for storage; the energy storage device is used to supply power to the gas stove body.

[0034] When the gas stove is in use, the temperature of its burner is relatively high and the heat generated is also relatively large. However, since these heats are currently dissipated into the air finally, a certain amount of energy is wasted. Therefore, the embodiment of the present invention considers utilizing these heats, converting them into electrical energy to supply power to the gas stove itself. At the same time, the embodiment of the present invention considers that when the user has not used the gas stove continuously for a long time, there may not be enough power to supply the gas stove. Therefore, this embodiment also utilizes the photovoltaic conversion device to convert light energy into electrical energy to more effectively realize the self - power supply function of the gas stove.

[0035] As Figure 3 and Figure 5As shown in the figure, the gas stove body includes: a panel 1, a housing 2, and a burner 3; the panel 1 is fixedly connected to the housing 2 to form a cavity; the burner 3 is embedded in the panel 1. In order to more simply and effectively achieve thermoelectric power generation, the thermoelectric power generation device in this embodiment is a thermoelectric power generation chip 4; the thermoelectric power generation chip 4 is arranged in the cavity; the hot end of the thermoelectric power generation chip 4 is arranged directly below the burner 3, and the hot end is in contact with the panel 1; the cold end of the thermoelectric power generation chip 4 is in contact with the bottom surface of the housing 2. In this way, the hot end of the thermoelectric power generation chip 4 can effectively collect the heat generated by the burner 3 during ignition, and form a certain temperature difference with the cold end of the thermoelectric power generation chip 4, so that the thermoelectric power generation chip 4 can effectively generate electricity using the above temperature difference.

[0036] In order to further effectively achieve thermoelectric power generation, in this embodiment, the hot end of the thermoelectric power generation chip 4 is arranged in a fitting manner with the panel 1, and the cold end of the thermoelectric power generation chip 4 is arranged in a fitting manner with the bottom surface of the housing 2. In this way, the temperature difference between the hot end and the cold end of the thermoelectric power generation chip 4 can be further effectively increased, so as to more effectively convert the heat energy generated by the gas stove body into electrical energy and store it in the energy storage device.

[0037] Thermoelectric power generation uses the heat generated by the gas stove itself and the thermoelectric power generation device to generate electricity, which can effectively meet the self-power supply requirements of the gas stove.

[0038] In order to ensure the safety and effectiveness of the use of the photoelectric conversion device and improve the service life of the photoelectric conversion device, in this embodiment, as Figure 3 shown, the photoelectric conversion device 5 is arranged in the cavity formed by the panel 1 and the housing 2, and the panel 1 is made of a transparent material so that light can pass through the panel 1; the light-collecting surface of the photoelectric conversion device 5 is arranged in a fitting manner with the panel 1, so that the photoelectric conversion device 5 can more effectively collect the light source.

[0039] In order to further improve the effectiveness of photoelectric conversion, in this embodiment, the photoelectric conversion device 5 is an amorphous silicon panel. Among them, the amorphous silicon panel is a visible light power generation device. When there is light, the amorphous silicon panel collects light energy and converts the light energy into electrical energy and stores it in the energy storage device.

[0040] And, the temperature at the joint of the amorphous silicon panel and the panel 1 is not greater than the first preset temperature threshold. That is, in this embodiment, the installation position of the amorphous silicon panel should be as far away from the burner 3 as possible, and should be arranged at a position with a lower temperature of the panel 1 as much as possible to avoid the high temperature generated by the open flame from affecting the amorphous silicon panel.

[0041] As Figure 2 and Figure 4As shown in the figure, the gas stove body in this embodiment further includes: a pulse igniter 6 for igniting the burner 3, and a touch screen 7 for displaying the power of the energy storage device. Among them, the pulse igniter 6 ignites the burner 3 through the discharge of the ignition needle 10, and the valve body 11 is used to control the pulse igniter 6 to start working. The energy storage device includes: a first energy storage battery 8 and a second energy storage battery 9; the pulse igniter 6, the touch screen 7, the first energy storage battery 8 and the second energy storage battery 9 are all arranged in the cavity to ensure the use safety; the touch screen 7 is arranged in a fitting manner with the panel 1 so that users can operate the touch screen accurately and effectively; the thermoelectric power generation sheet 4 is used to deliver the converted electric energy to the first energy storage battery 8 for storage; the photovoltaic conversion device 5 is used to deliver the converted electric energy to the second energy storage battery 9 for storage; the first energy storage battery 8 is used to supply power to the pulse igniter 6; the second energy storage battery 9 is used to supply power to the touch screen 7.

[0042] In this embodiment, when the touch screen 7 displays the power of the energy storage device, it can display the power of the first energy storage battery 8 and the power of the second energy storage battery 9 respectively, or can obtain the comprehensive power of the first energy storage battery 8 and the second energy storage battery 9 and display this comprehensive power. Users can set the specific power display method during use.

[0043] In this embodiment, the energy storage device is divided into two energy storage batteries. Each energy storage battery is used to store the electric energy converted by different methods, and each energy storage battery supplies power to different devices in the gas stove, which is beneficial to targeted monitoring and management of the power. The setting of the touch screen is beneficial for users to timely understand the power usage of the energy storage device.

[0044] In order to expand the functions of the touch screen and further improve the user experience, the touch screen 7 in this embodiment is further used to receive touch commands, and based on the touch commands, a clock display function and / or a timing function are realized. Among them, the timing function can be used when users cook porridge or soup. This embodiment can further set a time reminder function to further improve the user experience.

[0045] Moreover, the temperature at the joint of the touch screen 7 and the panel is not greater than the second preset temperature threshold. That is, in this embodiment, the installation position of the touch screen 7 should be as far away from the burner 3 as possible, and should be set at a position with a lower temperature of the panel 1 as much as possible to avoid the high temperature generated by the open flame from affecting the touch screen 7.

[0046] In this embodiment, the gas stove body further includes: a controller; both the first energy storage battery 8 and the second energy storage battery 9 are electrically connected to the controller; the controller is configured to: obtain the current power of the first energy storage battery 8 as the first power; obtain the current power of the second energy storage battery 9 as the second power; when it is determined that the first power is less than the first preset power threshold and the second power is greater than the second preset power threshold, control the second energy storage battery 9 to charge the first energy storage battery 8 until the absolute value of the difference between the first power and the second power is less than the third preset power threshold; when it is determined that the second power is less than the first preset power threshold and the first power is greater than the second preset power threshold, control the first energy storage battery 8 to charge the second energy storage battery 9 until the absolute value of the difference between the first power and the second power is less than the third preset power threshold.

[0047] That is, in this embodiment, the first energy storage battery 8 and the second energy storage battery 9 can charge each other to ensure the normal use of each component in the gas stove and avoid sudden power outages. Specifically, for example, if the first preset power threshold is set to 20% of the power, the second preset power threshold is set to 80% of the power, and the third preset power threshold is set to 5% of the power, then when the controller detects that the power of the first energy storage battery 8 is less than 20% and the power of the second energy storage battery 9 is greater than 80%, the controller controls the second energy storage battery 9 to charge the first energy storage battery 8 until the power difference between the second energy storage battery 9 and the first energy storage battery 8 is less than 5%, and then the charging can be stopped; when the controller detects that the power of the second energy storage battery 9 is less than 20% and the power of the first energy storage battery 8 is greater than 80%, the controller controls the first energy storage battery 8 to charge the second energy storage battery 9 until the power difference between the first energy storage battery 8 and the second energy storage battery 9 is less than 5%, and then the charging can be stopped.

[0048] In this embodiment, the touch screen 7 is electrically connected to the controller. To timely remind the user when the power of the energy storage battery is low and further improve the user experience, the controller in this embodiment is further configured to: when it is determined that the first power is less than the first preset power threshold and the second power is not greater than the second preset power threshold, control the touch screen 7 to perform a first charging reminder to remind the user to charge the first energy storage battery 8; when it is determined that the second power is less than the first preset power threshold and the first power is not greater than the second preset power threshold, control the touch screen 7 to perform a second charging reminder to remind the user to charge the second energy storage battery 9.

[0049] Specifically, both the first energy storage battery 8 and the second energy storage battery 9 are provided with charging ports to facilitate charging by an external power supply. Taking the above-mentioned preset power thresholds as an example, when the controller detects that the power of the first energy storage battery 8 is less than 20% and the power of the second energy storage battery 9 is not greater than 80%, at this time, the second energy storage battery 9 cannot charge the first energy storage battery 8, so the controller controls the touch screen 7 to give a first charging reminder to remind the user to charge the first energy storage battery 8; when the controller detects that the power of the second energy storage battery 9 is less than 20% and the power of the first energy storage battery 8 is not greater than 80%, at this time, the first energy storage battery 8 cannot charge the second energy storage battery 9, so the controller controls the touch screen 7 to give a second charging reminder to remind the user to charge the second energy storage battery 9.

[0050] Among them, the specific reminder method can be a text reminder, a pop-up dialog reminder, a voice reminder, etc. Of course, a buzzer can also be added to the gas stove body to remind the user to charge in the way of the buzzer sounding, or other methods that can attract the user's attention can be used to remind the user to charge. This embodiment does not make specific restrictions on this.

[0051] In actual application, when the user just buys a gas stove for the first time or does not use it for a long time for some reason and places it in a lightless environment, the energy storage battery of the gas stove can be charged through an external power supply.

[0052] In this embodiment, the first energy storage battery 8 or the second energy storage battery 9 is also used to supply power to the controller. That is, in this embodiment, the power consumption of the controller is also provided by the first energy storage battery 8 or the second energy storage battery 9 to further meet the self-power supply requirements of the gas stove.

[0053] In summary, in this embodiment, while using thermoelectric power generation, photovoltaic power generation is also utilized to form a complement. The energy storage battery for thermoelectric power generation and the energy storage battery for photovoltaic power generation can charge each other, and through the use of the two power generation devices, the power demand of the gas stove is met. And through this embodiment, the waste heat of the gas stove and the visible light in the environment can be fully utilized to achieve the effective utilization of energy.

[0054] The self-powered gas stove provided by the embodiment of the present invention converts the heat energy generated by the gas stove body into electrical energy through a thermoelectric power generation device and transports it to the energy storage device for storage, converts the light energy into electrical energy through a photovoltaic conversion device and transports it to the energy storage device for storage, and uses the energy storage device to supply power to the gas stove body, so that the gas stove can make full use of the light energy and the heat energy generated by itself to supply power to itself, rather than simply relying on battery power supply, thereby enabling the user not to replace the battery frequently. It can be seen that the technical solution provided by the embodiment of the present invention can effectively avoid the problem of inconvenient use caused by relying solely on battery power supply, thus greatly improving the user experience.

[0056] 1. The problem of frequently replacing the battery of the gas stove;

[0057] 2. Heat recovery of the gas stove and utilization of visible light for power generation.
