Embodiment Construction
[0036] It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.
[0037] The core idea of the present invention is: add an auxiliary temperature sensor for sensing the water temperature in the circulating waterway in the heat pump main unit of the heat pump water heater, and make a comprehensive judgment through the main temperature sensor in the water tank and the auxiliary temperature sensor in the heat pump main unit, It can effectively eliminate the detection deviation caused by abnormality, ensure the normal start and stop of the heat pump host, and when the main temperature sensor fails, the auxiliary temperature sensor can be used to control the start and stop of the heat pump host to ensure the user's water supply.
[0038] figure 1 It is a schematic flow chart of a preferred embodiment of the control method of the heat pump water heater in the present inv...
