Problems solved by technology

[0013] Second, after defrosting, the freezer needs to be re-cooled so that the temperature in the freezer drops to the temperature before defrosting, so the freezing efficiency of the refrigerator will decrease;
[0014] Third, when removing frost on the evaporator, an additional internal heat source is not used, but only the heater is used, so there is a disadvantage of increased power consumption

Abstract

The invention discloses a defrosting device for a refrigerator and a control method thereof. The refrigerator defrosting device of the present invention includes: an evaporator installed on the cold air supply part located on one side of the wall of the freezing chamber; an auxiliary evaporator that works when the evaporator is defrosted; installed on the cold air supply part for circulating the above A cooling fan in the freezer. According to the present invention, the temperature inside the freezer can be stably maintained during the defrosting operation of the refrigerator, and the power consumption can be reduced.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a defrosting device of the refrigerator and a control method thereof. Background technique [0002] Generally speaking, a refrigerator is generally composed of a refrigerator with a temperature of about 3°C ​​to 4°C for refrigerating food and a freezer with a temperature below 0°C for freezing food. [0003] The principle of the above-mentioned refrigerator will be briefly described below. [0004] The refrigerant in the refrigerant pipe of the refrigerator is compressed by the compressor into a state of high temperature and high pressure, and then sent to the condenser along the refrigerant pipe. Afterwards, the above-mentioned refrigerant is liquefied in the condenser and moves along the refrigerant pipe to the expansion valve, and then turns into a low-temperature and low-pressure state after passing through the expansion valve. In addition, the refrigerant moving along the refrigerant pipe...
