Problems solved by technology

[0002] During the operation of the refrigerator, due to factors such as water vapor brought in by the user when opening or closing the refrigerator door, frost will form on the surface of the evaporator of the refrigerator. When the surface of the evaporator of the refrigerator is frosted, the efficiency of heat exchange during cooling will be reduced , so it is necessary to defrost the surface of the evaporator

Abstract

The invention provides a refrigerator and a defrosting method thereof. The refrigerator provided by the invention comprises a refrigerating chamber; the air duct is connected with the refrigerating chamber, a first air door is arranged in the air duct and used for controlling the communication state of the air duct and the refrigerating chamber, and the communication state comprises communication and non-communication; the evaporator is arranged in the air duct, and when the first air door is opened, air in the refrigerating chamber makes contact with the surface of the evaporator for heat exchange; the defrosting assembly comprises a heater, and the heater is used for heating the evaporator; and the controller is used for controlling the matching relation of the state of the heater and the state of the first air door, so that heat energy generated during heating of the heater and heat energy of the refrigerating chamber when the first air door is opened are matched with each other to melt a frost layer on the surface of the evaporator.

Description

technical field [0001] The present application relates to the technical field of household appliances, in particular, to a refrigerator and to a method for defrosting a refrigerator. Background technique [0002] During the operation of the refrigerator, due to factors such as water vapor brought in by the user when opening or closing the refrigerator door, frost will form on the surface of the evaporator of the refrigerator. When the surface of the evaporator of the refrigerator is frosted, the efficiency of heat exchange during cooling will be reduced , so it is necessary to defrost the surface of the evaporator. [0003] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the application, and therefore may include information that does not constitute prior art known to those of ordinary skill in the art. Contents of the invention [0004] Embodiments of the present a...
