A one-way valve is provided on the pipeline connecting the equipment water outlet tap 4 and the refrigeration tank 3 to prevent the water in the equipment water outlet tap 4 from flowing back. The mixed water in the equipment water outlet tap 4 is prevented from flowing back into the heating tank or the refrigeration tank.

In a preferred embodiment, the heating tank 2 is a double-layer insulation tank, and a vacuum is drawn between the two layers to achieve insulation of the liquid in the tank and reduce energy consumption of repeated heating.

In a preferred embodiment, one of the branches is a reserved pipe, and its connecting end is left vacant for connecting to other external water-using equipment 7.

A one-way valve and a high-pressure switch 71 are arranged on the branch pipe, and the one-way valve is used to prevent water in other external water-using devices 7 from flowing back into the main pipe.

When other external water-using devices 7 use water, the water pressure in the branch pipe decreases, the high-pressure switch 71 opens, and the water purifier is started, so that the water purifier can continue to supply water; when other external water-using devices 7 stop using water, the water pressure in the branch pipe increases, and the water purifier stops working. At the same time, the one-way valve also prevents leakage in the branch pipe from causing the water purifier to start up by mistake.
