Embodiment 1

[0033] figure 1 A water return control system for an air source water heater provided in an embodiment of the present application.

[0034] Such as figure 1 As shown, the backwater control system provided in this embodiment includes a human detection device 10 and a control device 20 connected to the human detection device 10 .

[0035] The air source water heater in this embodiment includes an outdoor unit 200 , a water tank 210 , a circulating water pipe 220 , a water return pump 230 and at least one faucet 250 .

[0036] The outdoor unit 20 is configured outdoors, and is used to obtain heat energy from the air by using a heat pump principle, and input the obtained heat energy to the indoor water tank 210 through a refrigerant.

[0037] The water tank 210 has the function of heat exchange, that is, the heat energy in the refrigerant is taken out by using the heat exchanger principle, and the tap water in it is heated, and the heated tap water can meet people's needs for ho...

Embodiment 2

[0052] figure 2 It is a structural diagram of a water return control system for an air source water heater provided in another embodiment of the present application.

[0053] Such as figure 2 As shown, the water return control system provided in this embodiment is based on the previous embodiment with the addition of a water temperature detection device 260 .

[0054] The water temperature detection device 260 is arranged on the circulation pipeline 220 between the water return pump 230 and the water inlet 212 of the water tank 210, and is connected with the control device 20, and is used to detect the temperature of the tap water in the circulation water pipeline 220, and the temperature The temperature parameter described in the previous embodiment is output to the control device 20 as one of the basis for controlling the operation or shutdown of the return water pump 230 when there are people 110 in the room 100 .

[0055] The water temperature detection device 260 incl...

Abstract

The invention provides a water return control system of an air energy water heater. The water return control system comprises a person detecting device and a control device connected with the person detecting device. The person detecting device is used for detecting whether people are in a room, a signal showing that people are in the room is output to the control device when people are in the room, and a signal showing that nobody is in the room is output when nobody is in the room. The control device outputs a starting signal so as to control a water return pump to be started according to the signal showing that people are in the room and temperature parameters, or outputs a stopping signal so as to control the water return pump to be stopped according to the signal showing that nobody is in the room; accordingly, when nobody is in the room, the water return pump stops operation immediately, so that a large amount of electric energy is saved, and waste of electric energy is avoided.

Description

technical field [0001] The present application relates to the technical field of air-energy water heaters, and more specifically, relates to a water return control system for air-energy water heaters. Background technique [0002] The return water function of household air energy water heaters currently on the market is to use the return water pump to circulate the water in the water tank, so that the water temperature of the outlet water is constant and comfortable. However, continuing to recirculate the water when the room is unoccupied results in a waste of electrical energy. Contents of the invention [0003] In view of this, the present application provides a return water control system of a domestic air energy water heater to reduce the waste of electric energy. [0004] In order to achieve the above purpose, the proposed scheme is as follows: [0005] A water return control system for an air energy water heater, comprising: [0006] The personnel detection device...
