In summary, the working principle of the embodiment of the present disclosure is as follows: the electromagnetic valve 7 and the three-way valve 11 are in a normally closed state, a user presses a water feeding button on the controller 6, the electromagnetic valve 7 is opened, water in the water inlet pipe 8 flows into the water storage tank 1 through the third pipeline 18 and the water pipe 10, and when the water level sensor 4 detects that the water level in the water storage tank 1 reaches an upper limit, the controller 6 controls the electromagnetic valve 7 to be closed to stop water injection into the water storage tank 1. The water in the water storage tank 1 can be heated up when the sun is present in the daytime, so that the water can be used for the life of a user. Under the condition that the external environment temperature is kept at a low temperature continuously, for example, in winter in the north, when the second temperature sensor 12 detects that the environment temperature is low, the controller 6 monitors the temperature detected by the first temperature sensor 14 in real time, and when the temperature detected by the first temperature sensor 14 is lower than 4 ℃, the controller 6 controls the three-way valve 11 to be opened so as to communicate the first pipeline 16 with the water pipe 10, so that cold water in the water pipe 10 is discharged into the water receiving piece 15, and hot water in the water storage tank 1 is sequentially introduced into the water pipe 10 and the first pipeline 16 and is finally discharged into the water receiving piece 15. When the first temperature sensor 14 detects that the temperature of the water in the water pipe 10 is high, the three-way valve 11 may be controlled to be closed. As an example, the lower limit temperature of the water in the water pipe 10 is set to 4 degrees celsius, that is, when the temperature of the water in the water pipe 10 is detected to be lower than 4 degrees celsius, the three-way valve 11 needs to be controlled to open, so that the water pipe 10 is communicated with the first pipeline 16 to discharge the water in the water pipe 10; the upper limit temperature that sets up water in water pipe 10 is 20 degrees centigrade, need control three-way valve 11 and close when detecting the temperature of water in water pipe 10 exceedes 20 degrees centigrade promptly for intercommunication disconnection between water pipe 10 and the first pipeline 16 makes and fills with hot water in the water pipe 10, avoids water pipe 10 to take place the condition of frost crack. Through this kind of mode of setting, can guarantee that the water in the water pipe 10 can not freeze, the user can use hot water at any time, simultaneously better water economy resource.

In the case where the external environment is maintained at a low temperature for a long time and there is no sunlight in the daytime, the temperature of the water in the water storage tank 1 is gradually lowered. At this moment, when the temperature of water in the water storage tank 1 is lower than 20 ℃, if the temperature of water in the water pipe 10 is lower than 4 ℃, the three-way valve 11 is opened, the water in the pipeline 10 flows into the water receiving part 15 through the first pipeline 16, so that the temperature of the water flowing through the pipeline 10 is also lower than 20 ℃, the three-way valve 11 is always in an open state, the water is continuously drained until all the water in the water storage tank 1 is drained, therefore, the water pipe 10 can be prevented from being frozen, meanwhile, the water in the water storage tank 1 can be prevented from being frozen, and the loss of a user is reduced. To sum up, this application provides one kind and heats through solar energy resource to the water in the storage water tank 1 and prevents frostbite, need not adopt the mode of electrical heating, reduces the conflagration hidden danger. Meanwhile, the water discharging amount is low in the water discharging process, and the water resource waste can be reduced by arranging the water receiving piece 15.
