Abstract

The invention discloses a control method of a heat pump water heater. When the heat pump water heater is in the first control mode, the control method includes the following steps: S1: inject water into the main water tank through the water inlet and close the circulating pump and the control valve, and the first heat exchange The module heats the main water tank, and controls the first temperature detection device to detect the water temperature T1 in the main water tank; S2: when the detected water temperature T1 reaches the first preset temperature TS1, turn on the circulating pump and the control valve to inject water into the circulating water tank and Control the second heat exchange module to heat the circulating water tank, and control the second temperature detection device to detect the water temperature T2 in the circulating water tank; S3: When the detected water temperature T2 reaches the second preset temperature TS2, the water outlet is opened. According to the control method of the heat pump water heater of the present invention, the operation is relatively convenient, which not only shortens the time for users to wait for hot water, makes water use more convenient for users, but also saves energy and reduces the use cost of the heat pump water heater.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a control method for a heat pump water heater. Background technique [0002] In the related art, during the use of the heat pump water heater, if the heat pump water heater is not turned on in advance, the user has to wait for a long time to obtain hot water, which brings great inconvenience to the user. If the heat pump water heater is always turned on, although hot water can be obtained immediately, it will cause a lot of energy waste, thereby greatly increasing the use cost of the heat pump water heater. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a control method of the heat pump water heater, which is easy to operate, can shorten the user's waiting time for hot water, and save the use cost of the heat pump water heater. ...
