Abstract

The invention provides a defrosting method and a water heater. The defrosting method comprises the steps that the heating operation time of a compressor in the water heater is obtained; whether to enter a defrosting mode or not is determined according to the heating operation time; after it is determined that the water heater enters the defrosting mode, the environment temperature and the temperature of an outdoor coil pipe in the water heater are obtained; and defrosting is carried out according to the environment temperature and the temperature of the outdoor coil pipe. According to the defrosting method, after the defrosting mode is determined according to the heating operation time of the compressor, it is indicated that an evaporator possibly has the frosting problem, whether the evaporator has the frosting problem needs to be further determined, and then the environment temperature and the outdoor coil pipe temperature are obtained, so that whether the evaporator has the frosting problem or not is further determined according to the environment temperature and the outdoor coil pipe temperature, if it is determined that the evaporator has the frosting problem, defrosting is carried out, that is, defrosting is carried out when it is determined that the evaporator has the frosting problem, accurate control over defrosting is achieved, the problem of frost-free defrosting is avoided, and therefore the existing problem of resource waste is avoided.

Description

technical field [0001] The invention belongs to the technical field of water heaters, and in particular relates to a defrosting method and a water heater. Background technique [0002] With the continuous improvement of living standards, more and more users use heat pump water heaters for heating to produce hot water. During the heating operation of the heat pump water heater, the evaporator in the heat pump water heater is prone to frosting. Therefore, in the process of using the heat pump water heater, it is necessary to defrost the evaporator, that is, to defrost. [0003] In the prior art, defrosting is generally performed at regular intervals, that is, the evaporator is defrosted after the heating operation of the heat pump water heater exceeds a certain period of time. [0004] However, the inventors found that the evaporator is defrosted after the heating operation exceeds a certain period of time, and the evaporator is not actually frosted at this time, which leads ...
