[0079] The control module 600 is electrically connected to the traction device 71. The water path from the water discharge control valve 16, the pressure device 73 to the first pipeline is used as a return water path, and the water not needed by the water outlet module 200 is returned through the return water path, thereby realizing the discharge of the water not needed by the water outlet module 200, so that the water outlet module 200 always discharges water that meets the requirements; the water in the heating and heat storage module 400 is discharged through the loop module, which is conducive to the discharge of the unwanted water in the heating and heat storage module 400, avoiding the water circulation heating affecting the state of the circulating heat exchange circuit, thereby helping to extend the service life of the circulating heat exchange circuit.

[0080] In a further optional embodiment of the present embodiment, the control module 600 is electrically connected to the pressure device 73 and the traction device 71 .

[0084] The water in the heating and thermal storage module 400 is discharged from the water passages corresponding to the heating and thermal storage module 400, the pressure device 73, the first pipeline, the traction device 71, and the second pipeline 72. Thus, the unwanted water in the heating and thermal storage module 400 is discharged.

[0085] The water from the water discharge control valve 16 to the traction device 71 is discharged from the water passages corresponding to the water discharge control valve 16 , the pressure device 73 , the first pipeline, the traction device 71 , and the second pipeline 72 .

[0086] In another optional embodiment, the number of the traction devices 71 is two; the first end of the pressure device 73 is communicated with one end of the water discharge control valve 16, the second end of the pressure device 73 is communicated with one end of the first pipeline, and one end of the first traction device 71 is communicated with the other end of the first pipeline, so as to discharge water from the water discharge control valve 16 to the pressure device 73;

[0089] It is understandable that if the power of the traction device 71 is large enough and the pressure bearing capacity of the heated hot tank 41 is not a problem, the reflux component does not need to be replenished with air. Otherwise, the reflux component is required to replenish air when the traction device pumps water to the second pipeline.

[0090] Optionally, the reflux component adopts an airflow control valve and an air inlet, the control module 600 is electrically connected to the airflow control valve, and the airflow control valve is connected to one end of the faucet control valve 16 through the air inlet.

[0095] The control module 600 is electrically connected to the heating subunit. The heat storage subunit stores the flowing medium containing heat energy, thereby storing a certain amount of heat energy in advance, effectively solving the problem of insufficient supply during peak water consumption in the instant heating mode, and ensuring a stable and sufficient supply of hot water even when a large amount of water demand occurs.

[0096] It can be understood that the heating tank 41 of the heating and heat storage module 400 includes: a heating subunit and a heat storage subunit.

[0097] The heat storage subunit uses a container that can hold the flow medium, and the flow medium is stored in the container cavity. The heat storage subunit is provided with a drain port and a reflux port. The flow medium in the reflux port of the heat storage subunit is output from the drain port of the heat storage subunit to one end of the second heat exchange tube of the heat exchange module 300, and then enters the reflux port of the heat storage subunit through the other end of the second heat exchange tube of the heat exchange module 300, and then enters the heat storage subunit.

[0098] The heating subunit is a component with a heating function.

[0099] It is understandable that the heating subunit can be located outside the heat storage subunit, and the heating subunit heats the flowing medium in the accommodating chamber through the heat storage subunit. The heating subunit can also be partially located in the accommodating chamber, and the heating subunit heats the flowing medium in the accommodating chamber by directly contacting the flowing medium in the accommodating chamber.

[0105] In one embodiment, the instant heating module 500 includes a thick film heater 51. The thick film technology is adopted to print the heating resistor material on the insulating substrate by screen printing and other processes, and then it is processed by high temperature sintering and other processes. The thick film heater 51 has the advantages of rapid heating, high thermal efficiency, stable performance, and long service life.

[0106] The instant heating module 500 may also use a heater designed using a technology other than thick film technology.

[0107] In one embodiment, the flow medium in the heating and heat storage module 400 is water; when the water outlet module 200 does not drain water, the instant heating module 500 is also used to heat the water input into the instant heating module 500 and then transport it to the heating and heat storage module 400. When the water outlet module 200 does not drain water, the instant heating module 500 stores heat energy in the heating and heat storage module 400, which is conducive to improving the efficiency of storing heat energy.

[0108] It can be understood that, in this embodiment, the instant heating module 500 further includes: a first instant heating reflux valve. The first instant heating reflux valve adopts a one-way valve. The water outlet of the instant heating module 500 is connected to the heating and heat storage module 400 through the first instant heating reflux valve, that is, when the first instant heating reflux valve is turned on, the water output from the water outlet of the instant heating module 500 (the water heated by the instant heating module 500) enters the heating and heat storage module 400, thereby realizing the input of water for storing thermal energy into the heating and heat storage module 400. The first instant heating reflux valve adopts a one-way valve, so that the water output from the water outlet of the instant heating module 500 can enter the heating and heat storage module 400, while the water in the heating and heat storage module 400 cannot enter the instant heating module 500 through the water outlet of the instant heating module 500.

[0110] Optionally, the instant heating module 500 further includes an instant heating input pump. The control module 600 is connected to the instant heating input pump by telecommunication. The instant heating input pump is a water pump. The instant heating input pump is used to pump water from the heating and heat storage module 400 to the water inlet end of the instant heating module 500.

[0111] Optionally, the heating and heat storage module 400 further includes: a second instant heating reflux valve, and the control module 600 is electrically connected to the second instant heating reflux valve.
