When the four-way valve 3 is closed, the solenoid valve 2 below the solar water heater tank is closed, and at the same time the four-way valve 3 is connected to the solar water heater outlet pipe and the heat preservation water storage tank 4, and the residual water in the water outlet pipe is pressed into the heat preservation water storage tank 4 due to its own gravity . When the hot water is used next time, the instant hot water can be used from the insulation water storage tank 4 earlier. This will not only prevent freezing, but also avoid waste of water resources caused by draining the residual water.

This device is a reasonable design of the four-way valve to realize 5 different stalls of the antifreeze device of the solar water heater, respectively obtain warm water in the heat preservation water storage tank, tap water cold water, mixed water of tap water and solar hot water, solar hot water and shut off In the state, the solar hot water is introduced into the heat preservation water storage tank for the next use.
