When the external environment temperature is higher than or equal to 26 ℃, the control module 1 analyzes and arranges the temperature signal, meanwhile, the control module 1 sends a command signal to the relay switch 4, the relay switch 4 is disconnected for conducting, and the energy-saving power supply device 7 stops supplying electric energy to the water storage type electric water heater 5.
It is understood that the temperature start value may be set to a range of values, for example, the temperature start value range is set to within 25 ℃ to 30 ℃.

Specifically, the inner container 52 is used for storing water, and the temperature control module 54 detects the temperature of the water.
It can be understood that the water source of the inner container 52 is injected from the water inlet 55, after the inner container 52 is filled with the water to be heated, the power supply supplies power to the electric heating rod through the temperature control module 54, the electric heating rod starts to work to heat the water in the inner container 52, and meanwhile, the temperature control module 54 detects the temperature of the water in the inner container 52 in real time. When the temperature control module 54 detects that the temperature of the water in the inner container 52 is consistent with the temperature set by the temperature control module 54, the temperature control module 54 cuts off the power supply of the electric heating rod to stop heating the water in the inner container 52.
