[0002] Gas water heaters consist of a combustion chamber and a water tank. The flame generated in the combustion chamber heats the water flowing through the tank to produce hot water. A portion of the heat generated during combustion is used for heat exchange in the water tank, while the remaining heat is directly released into the atmosphere, resulting in energy waste. The combustion chamber shell is cooled using multi-layered panels, insulation cotton, and air cooling, resulting in a complex structure and poor cooling effect.

[0012] In some embodiments of this application, a gap is formed between the circumferential wall and the housing, and the heat dissipation portion faces the gap.
[0013] In some embodiments of this application, the circumferential wall includes an inner layer plate and an outer layer plate, the mounting cavity is formed between the inner layer plate and the outer layer plate, one end of the semiconductor thermoelectric generator is connected to the inner layer plate, and the heat dissipation part is connected to the outer layer plate.
[0014] In some embodiments of this application, the circumferential wall of the combustion chamber shell is composed of four side walls, and the semiconductor thermoelectric generator is disposed inside any one of the side walls.
[0015] In some embodiments of this application, multiple semiconductor thermoelectric generators are connected in series.
[0016] In some embodiments of this application, the electrical energy generated by the semiconductor thermoelectric generator is used in the power consumption module of the gas water heater.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are:
[0021] When a gas water heater is operating, the internal temperature of the combustion chamber is higher than the external temperature. A thermoelectric generator is placed inside the combustion chamber shell, with one end of the generator located on the high-temperature side and the other end on the low-temperature side. The temperature difference between the two sides of the thermoelectric generator generates a potential difference, which in turn produces electricity to power other electrical devices.

[0045] In some embodiments of this application, a gas water heater is provided, as shown in the reference... Figure 1 It includes a housing 100, which constitutes the outer shell of the gas water heater, and an installation space 110 is formed inside the housing 100.
[0046] The gas water heater also includes a water tank 200, which is disposed within the installation space 110. The water tank 200 can be a coiled water tank or a non-coiled water tank. The water tank 200 is connected to an inlet pipe 210 and an outlet pipe 220. The inlet pipe 210 and the outlet pipe 220 extend from the housing 100 for connection to external piping.
[0047] The gas water heater also includes a combustion chamber 300 disposed within the installation space 110, the combustion chamber 300 being configured to heat water flowing through the water tank 200. Figure 2 This is a structural diagram of combustion chamber 300. Figure 3 for Figure 2 Sectional view along line AA, Figure 4 for Figure 2 Cross-sectional view along line BB. For example, the combustion chamber 300 is located below the water tank 200, and the flame generated by the combustion chamber 300 heats the water tank 200, thereby heating the water flowing through the water tank 200 to produce hot water.
[0048] The combustion chamber 300 has an installation cavity 313 formed inside its shell. The shell of the combustion chamber 300 is hollow, which is beneficial for heat insulation.
[0049] The gas water heater also includes a thermoelectric generator 400, which is disposed within the mounting cavity 313, making full use of the internal space of the combustion chamber 300. One end of the thermoelectric generator 400 is connected to the inner wall of the combustion chamber 300, and the other end is provided with a heat dissipation part (not shown), which is connected to the outer wall of the combustion chamber 300.
[0050] When the gas water heater is working, the internal temperature of the combustion chamber 300 is higher than the external temperature of the combustion chamber 300. A semiconductor thermoelectric generator 400 is placed in the inner cavity of the casing of the combustion chamber 300. One end of the semiconductor thermoelectric generator 400 is located on the high-temperature side of the combustion chamber 300, and the other end is located on the low-temperature side of the combustion chamber 300. Utilizing the Seebeck effect, a potential difference is generated through the temperature difference on both sides of the semiconductor thermoelectric generator 400, thereby generating electrical energy to power other electrical devices and realizing the utilization of waste heat from the combustion chamber 300.
[0051] In other words, by setting a semiconductor thermoelectric generator 400 in the inner cavity of the combustion chamber 300 shell, the semiconductor thermoelectric generator 400 generates electrical energy by utilizing the temperature difference between the inside and outside of the combustion chamber 300. Part of the heat generated by combustion in the combustion chamber 300 is used to heat the water tank 200, and the other part is used to generate electricity in the semiconductor thermoelectric generator 400, thereby realizing the utilization of the waste heat of the combustion chamber 300 and avoiding heat waste.
[0052] The semiconductor thermoelectric generator 400 has a heat dissipation part, such as a heat sink, on one end outside the combustion chamber 300. The air outside the combustion chamber 300 can dissipate heat to the heat dissipation part, so that the two ends of the semiconductor thermoelectric generator 400 have a relatively stable temperature difference and a high temperature difference, which helps to improve the generation of electrical energy.
[0053] The heat dissipation unit is located on the outside of the combustion chamber 300 housing. The flowing air dissipates heat from the heat dissipation unit, which also helps to improve the heat dissipation and cooling effect of the combustion chamber 300 housing.
[0054] In some embodiments of this application, the mounting cavity 313 is formed inside the circumferential wall 310 of the combustion chamber 300 housing, one end of the semiconductor thermoelectric generator 400 is connected to the inner wall of the circumferential wall 310, and the heat dissipation part is connected to the outer wall of the circumferential wall 310.
[0055] The circumferential wall 310 of the combustion chamber 300 shell forms a combustion chamber, and the semiconductor thermoelectric generator 400 is placed in the inner cavity of the circumferential wall 310. By making full use of the inner cavity space of the circumferential wall 310, the area of the semiconductor thermoelectric generator 400 can be maximized, thereby improving the power generation capacity.
[0056] In some embodiments of this application, a gap 320 is formed between the circumferential wall 310 and the housing 100, and the heat dissipation part faces the gap 320.
[0057] The gap 320 serves as a gap for gas flow. The side of the heat sink facing the gap 320 helps the flowing gas to dissipate heat from the heat sink, improving the heat dissipation effect of the heat sink. This, in turn, makes the two ends of the semiconductor thermoelectric generator 400 have a relatively stable temperature difference, and the higher temperature difference helps to improve the generation of electrical energy.
[0058] In some embodiments of this application, the circumferential wall 310 includes an inner layer plate 311 and an outer layer plate 312, and the mounting cavity 313 is formed between the inner layer plate 311 and the outer layer plate 312. One end of the semiconductor thermoelectric generator 400 is connected to the inner layer plate 311, and the heat dissipation part is connected to the outer layer plate 312.
[0059] The circumferential wall 310 has a hollow structure formed by the inner layer plate 311 and the outer layer plate 312, which itself forms a thermal insulation structure. The thermoelectric semiconductor 400 is placed between the inner layer plate 311 and the outer layer plate 312 to make full use of the internal cavity space of the circumferential wall 310.
[0060] In some embodiments of this application, the circumferential wall 310 of the combustion chamber 300 is composed of four side walls, and the semiconductor thermoelectric generator 400 is disposed inside any one of the side walls.
[0061] That is, the circumferential walls 310 of the combustion chamber 300 form a rectangular structure, and a semiconductor thermoelectric generator 400 is provided in each side wall. This makes full use of the internal space of each side wall, increases the number of semiconductor thermoelectric generators 400, and thus improves the power generation capacity.
[0062] In some embodiments of this application, multiple semiconductor thermoelectric generators 400 are connected in series, which facilitates circuit connection, simplifies circuit structure, and facilitates unified control of multiple semiconductor thermoelectric generators 400.
[0063] In some embodiments of this application, the electrical energy generated by the thermoelectric generator 400 is used in the power supply module 800 of the gas water heater. For example, the power supply module 800 of the gas water heater includes indicator lights, a display screen, etc.
[0064] In some embodiments of this application, reference is made to Figure 5 The gas water heater also includes a rectifier module 500 and a controller 600. The semiconductor thermoelectric generator 400 is connected to the rectifier module 500, and the rectifier module 500 is connected to the controller 600.
[0065] In the combustion chamber 300 of the gas water heater, the flame burns, and the temperature difference between the inside and outside of the combustion chamber 300 generates a potential difference across the semiconductor thermoelectric generator 400, forming a current. The current is then rectified by the rectifier module 500 for voltage boosting and stabilization, and then transmitted to the electrical devices by the controller 600 to meet the power needs of other electrical devices.
[0066] In some embodiments of this application, reference is made to Figure 5 The gas water heater also includes a rectifier module 500, a controller 600, and an energy storage module 700. The semiconductor thermoelectric generator 400 is connected to the rectifier module 500, the rectifier module 500 is connected to the controller 600, and the controller 600 is connected to the energy storage module 700.
[0067] In the combustion chamber 300 of the gas water heater, the flame burns and a temperature difference is generated between the inside and outside of the combustion chamber 300. This causes a potential difference to be generated across the two ends of the semiconductor thermoelectric generator 400, forming a current. The current is then rectified by the rectifier module 500 for voltage boosting and stabilization, and then the rectified current is sent to the energy storage module 700 for storage by the controller 600.
[0068] In some embodiments of this application, the energy storage module 700 is connected to the power consumption module 800 of the gas water heater, and / or to an external power consumption device.
[0069] The electrical energy stored in the energy storage module 700 can power the indicator lights, display screens, and other power-consuming modules 800 of the gas water heater, or it can power other household appliances besides the gas water heater.
[0070] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.
