The utility model discloses theory of operation of embodiment:

the electronic heat pump 33 is a thermoelectric refrigerator, and the mechanism of hot spot refrigeration is completely different from vapor compression refrigeration and absorption refrigeration. It is a refrigeration method based on thermoelectric phenomenon. Two different metal wires are connected with each other to form a closed circuit, and two connecting points are respectively placed at two positions with different temperatures, so that a potential difference, namely contact electromotive force, is generated between the two connecting points. The current passes through the closed circuit of the colleague. Conversely, a closed circuit formed by connecting two different wires to each other is energized with direct current, which results in two connection points of different temperatures. When direct current is applied, one of the connection points is heated and the other connection point is cooled. This is the peltier effect, also known as the thermoelectric phenomenon. The thermoelectric cooler is used as a heat pump when working, heat is transferred from one point to another point, and the thermoelectric cooler is not used for a common heat absorption process or magic heat is transferred to a hot end, so that the thermoelectric cooler completely conforms to a thermodynamic process. In order to complete a heat flow cycle, the thermoelectric cooler must be connected to a suitable heat sink to dissipate the heat transferred from the cold side and the heat generated by the cloud-star process.

When the solar water heater works, a set hot water temperature value is set through the power controller 9, when the heat absorbed by the flat-plate solar heat absorber 12 is strong enough, the temperature sensor 62 senses that the set temperature value can be reached, the electronic heat pump 33 is turned off, and hot water generated by the solar water heater 1 enters the heat preservation water temperature along the copper pipe 31; when the heat absorbed by the flat solar heat absorber 12 is not strong enough, the temperature sensor 62 senses that the temperature reaches a set temperature value, the power controller 9 starts the electronic heat pump 33, the electronic heat pump 33 transfers the heat absorbed by the flat solar heat absorber 12 and the heat in the air to the copper plate 34, the heat of the copper plate 34 is transferred to the copper pipe 31 in the copper pipe 31 through heat transfer, the water temperature rises, and the heat enters the heat-preservation water tank 2 through a water path. The cold water in the water tank 11 of the solar water heater 1 is also changed into hot water through the heat transfer of the copper pipe 31 and then enters the heat preservation water tank 2.

Although the embodiments of the present invention have been described with reference to the accompanying drawings, various changes and modifications can be made by the owner within the scope of the appended claims, and the protection scope of the present invention should not be exceeded by the claims.
