[0051] Working or installation process:

[0052] Initial state: the valve core 18 is in an open state;

[0053] When it is needed, the first water pump 11 is started, and the first water pump 11 extracts part of the hot water in the hot water tank and transports it to the inner middle of the valve body 15 through the water inlet pipe 14. The hot water entering the inner space of the valve body 15 flows in from the water inlet of the valve core 18 and flows out from the water outlet of the valve core 18 and enters the first water pump 11 through the liquid inlet of the first water pump 11. The hot water passes through the first water pump 11 and flows out from the liquid outlet of the first water pump 11. The hot water flowing out of the liquid outlet of the first water pump 11 enters the first water pipe 16 and flows into the plate heat exchanger 12 through the diversion of the first water pipe 16, so that there is a part of hot water in the plate heat exchanger 12.

[0054] When part of the hot water enters the plate heat exchanger 12, the first water pump 11 stops starting, the valve core 18 is closed, the second water pump connected to the connecting pipe 13 is started, and the tap water in the water pipe is introduced into the connecting pipe 13 through the second water pump. The connecting pipe 13 guides the tap water into the second water pipe 17. The second water pipe 17 guides the tap water into the plate heat exchanger 12 to perform heat exchange and heat the tap water.
