When the hot water valves in the hot water pipeline are all in a closed state, the power supply of the supercharged circulating water pump is started, the water pressure of the water outlet of the water pump is larger than that of the water inlet, so that the pressure of the check valve at the tail end of the hot water pipe is larger than that of the tap water pipeline, the check valve is automatically opened, cold water in the hot water pipeline flows into the tap water pipeline, and hot water in the water heater flows to water end equipment automatically. Because the distance between the water-using end equipment connected in series in the hot water pipeline and the water heater is different, although cold water does not flow out, cold water still flows out when the hot water switch valve is opened too early, hot water also exists in the tap water pipeline when the hot water switch valve is opened too late, and particularly, the risk of incapability of use or scalding is caused when the temperature of the hot water is too high (refer to fig. 2).

A second thermocouple 82 is provided in the hot water pipe 31 on the water heater 10 side.
In the utility model, the working principle is as follows:
1. when the effective communication function can be realized between the circulating water pump 20 and the water consumption point 50, when a user opens a circulating water start-stop switch 425 on the water consumption device 51 (a faucet, a shower and other devices), and the first thermocouple 81 detects that the water temperature in the hot water pipeline of the water consumption point 50 is lower than a set value (for example, 38-42 ℃), the MCU processor 423 is connected with the communication circuit 411 of the first controller 41 through the communication circuit 422, the control circuit 412 controls the circulating water pump 20 to be switched from a closed state to an open working state, so that the first flow meter 61 connected in series in the cold and hot water pipelines of the water heater 10 generates an effective pulse signal and sends the effective pulse signal to the control circuit 412, the circulating water pump 20 keeps working, and the water consumption point 50 switches the first switch valve 71 from a closed state to an open and conductive state, so that the cold and hot water pipelines form effective internal circulation; when the hot water flows to the first thermocouple 81 at the hot water port of the water using device 51 and the temperature of the hot water reaches or exceeds the set water temperature (for example, 38-42 ℃), the MCU processor 423 turns the first switch valve 71 from the on state to the off state, so as to turn the internal circulation water route of the hot and cold water from the on state to the off state, and simultaneously, the control circuit 412 turns the circulation water pump 20 from the on state to the off state through the first communication module 411 by the active communication signal connection. Meanwhile, the acousto-optic prompt circuit of the water using equipment reminds the user that hot water can be used.
2. When a user turns on a circulating water start-stop switch 425 on a water consumption device 51 (a faucet, a shower and other devices), and an effective communication function cannot be established between a control circuit for controlling the start and stop of the circulating water pump 20 and a water consumption point 50, and when the first thermocouple 81 detects that the water temperature in the hot water pipeline 31 at the water consumption end is lower than a set value (for example, 38-42 ℃), the MCU processor 423 on the second controller 42 turns on the second switch valve 72 connected in series with the hot water pipeline 31, so that the second switch valve is turned off after the water flow flowing out of the water discharge pipe 53 is opened for a certain time (usually, a period of 3-5 seconds). The first flowmeter 61 connected in series in the cold and hot water pipelines 32 of the water heater 10 generates an effective pulse signal and sends the effective pulse signal to the first controller, the first controller 41 controls the circuit to start the circulating water pump 20 to enter a working state, and simultaneously the first switch valve 71 is switched from a closed state to an open and conductive state by a water utilization point, so that the cold and hot water pipelines form effective internal circulation. When the hot water flows to the first thermocouple 81 at the hot water port of the water using device 51, and the temperature of the hot water reaches or is higher than the set water temperature (for example, 38-42 ℃), the MCU processor 423 switches the first switch valve 71 from the on state to the off state, so that the internal circulation water path of the hot and cold water is switched from the on state to the off state, the first flow meter 61 connected in series in the water path of the first flow meter 61 in the cold and hot water pipeline 32 of the water heater 10 cannot generate a continuous effective pulse signal to the first controller, and the first controller 41 turns off the circulation water pump 20 to be in the stopped state. Meanwhile, the acousto-optic prompt circuit of the water using equipment reminds the user that hot water can be used.
Furthermore, the first controller 41 includes a control circuit 412, and a first communication module 411 and a first power source 413 electrically connected to the control circuit 412, the second controller includes an MCU processor 423, and a second communication module 422, a second power source 421, an input device 424 and an audio-visual prompt module 426 electrically connected to the MCU processor 423, the first communication module 422 can communicate with the first communication module 411, and the circulating water start-stop switch 425 can be integrated with the water-using equipment 51 or can be a split structure.
