Abstract

The invention relates to the technical field of refrigerators, and discloses a method for defrosting an evaporator of a refrigerator. The evaporator comprises a heat dissipation element, a refrigerant pipe and an electromagnetic heating element, wherein the refrigerant pipe is arranged on the heat dissipation element in a penetrating mode, the electromagnetic heating element comprises an electromagnetic heating pipe and a coil arranged outside the electromagnetic heating pipe, the electromagnetic heating pipe communicates with the refrigerant pipe, and the electromagnetic heating element is arranged between a refrigerant inlet and a refrigerant outlet of the evaporator. The method comprises the steps of acquiring the accumulated working time of a compressor; and when the accumulated working time is longer than or equal to the first time, starting the electromagnetic heating element of the evaporator, and defrosting the evaporator. According to the method provided by an embodiment of the invention, the defrosting speed of the evaporator is increased. The invention further discloses a device for defrosting the evaporator of the refrigerator and the refrigerator.

Description

technical field [0001] The present application relates to the technical field of refrigerators, for example, to a method and device for defrosting an evaporator of a refrigerator, and a refrigerator. Background technique [0002] During the use of the refrigerator, the surface of the evaporator will have different degrees of frosting. If the defrosting treatment is not carried out in time, the thickness of the frost layer on the surface of the evaporator will gradually increase, making the gap between the air inlet and the air outlet of the evaporator The circulation speed of the airflow will become smaller and smaller, the airflow circulation will not be smooth, and the cooling capacity will decrease, resulting in lower working efficiency of the refrigerator. [0003] At present, electric heating tubes are generally used to defrost the evaporator. [0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the foll...
