Set up first check valve 1 on the hot water inlet tube 3, set up second check valve 14 on the cold water inlet tube 13, set up third check valve 11 on circulating pipe 12, avoid the water backward flow.

The working process of the device is as follows:

1) clicking a 'start' button of the display panel XS1, enabling the first electromagnetic valve Y1, the third electromagnetic valve Y3 and the sixth electromagnetic valve Y6 to act, enabling cold water in the early stage of the system to enter the water tank 8, enabling the water temperature detectors to start feeding back signals, and displaying the current water temperatures (the hot water temperature, the cold water temperature, the mixed water temperature and the water temperature in the water tank) on the display panel XS1 in real time.

2) According to the cold water temperature and the hot water temperature displayed by the display panel XS1, the water mixing valve is manually adjusted until the temperature of the mixed water is T (for example, T is more than or equal to 37 ℃ and less than or equal to 40 ℃), a 'confirm' button is pressed on the display panel XS1, a signal is transmitted to the controller 15, the first electromagnetic valve Y1 and the third electromagnetic valve Y3 are closed, the water pump M1 is started, and after the countdown is 5S, the controller 15 determines the next operation according to the water temperature detected by the water temperature detector T4 in the water tank 8.

When the water temperature in the tank is less than or equal to 37 ℃ (most of the water temperature is the present case), namely the water temperature in the water tank 8 is less than or equal to 37 ℃, the second electromagnetic valve Y2 is opened to supplement hot water, the stirrer M2 is started simultaneously to fully mix the pipeline hot water with the original water in the water tank 8, the sixth electromagnetic valve Y6 is kept opened to continue circulation at the moment, when the water temperature detected by the water temperature detector T4 in the tank is increased to 37 ℃, the second electromagnetic valve Y2 is closed, the stirrer M2 is closed, and the water temperature is fed back to the controller 15.

When the temperature of water in the tank is higher than 40 ℃, namely the temperature of the existing water in the water tank 8 is higher than 40 ℃, the fourth electromagnetic valve Y4 is opened to supplement cold water, the stirrer M2 is started to fully mix the pipeline cold water with the original water in the water tank 8, the sixth electromagnetic valve Y6 is kept opened to continue circulation at the moment, the temperature of the water detected by the water temperature detector T4 in the tank is reduced to 38 ℃ (the temperature is fixed to 38 ℃ because of detector delay error and scalding prevention), the fourth electromagnetic valve Y4 is closed, the stirrer M2 is closed, and the water is fed back to the controller 15.

3) And opening the fifth electromagnetic valve Y5, closing the sixth electromagnetic valve Y6, starting normal water supply, continuing to operate the water pump M1 at the moment, closing the first electromagnetic valve Y1 and the third electromagnetic valve Y3, and taking the discharged water as the mixed water in the water tank 8. The water level detector Z1 detects the water level in the water tank 8, when the water level in the water tank 8 reaches the pump stopping water level, namely the water in the water tank 8 is basically used up, the first electromagnetic valve Y1 and the third electromagnetic valve Y3 are opened, meanwhile, the water pump M1 is stopped, and the cold and hot water pipes are used for supplying water normally.

4) After the use is completed, the "stop" button on the display panel XS1 is clicked, and the controller 15 controls to close the first solenoid valve Y1, the third solenoid valve Y3, and the fifth solenoid valve Y5, and the operation is ended.

It should be noted that, in the whole process, the mixing valve 6 is only manually adjusted at the beginning to make the mixed water temperature in the water outlet pipe 4 reach the proper temperature, at this time, the water supplied by the cold and hot water pipes is mixed to be the proper water temperature, and then the mixing valve 6 is not needed to be adjusted, and the water outlet is realized by the controller 15 controlling the actions of the electromagnetic valves and the water pump M1 according to the water temperatures.

The above disclosure is only for the preferred embodiments of the present invention, but the present invention is not limited thereto, and any person skilled in the art can think of the inventive changes, and several improvements and decorations made without departing from the principle of the present invention should fall within the protection scope of the present invention.
