Refrigerator defrosting control method and refrigerator

Abstract

The invention provides a refrigerator defrosting control method and a refrigerator. The refrigerator defrosting control method comprises the following steps: acquiring a refrigerator defrosting startsignal; according to the refrigerator defrosting start signal, enabling a compressor, a draught fan, a heating device and a branch air-supply device to work in a working state corresponding to the refrigerator defrosting start signal; acquiring a refrigerator defrosting end signal and the temperature of the branch air-supply device; and enabling the branch air-supply device to continuously run when the temperature of the branch air-supply device is lower than the first preset temperature, acquiring the integral temperature in the running process, and enabling the branch air-supply device to stop the continuous running when the integral temperature is lower than the preset value and the temperature of the branch air-supply device is lower than the second preset temperature. By adoption of the refrigerator defrosting control method provided by the invention, whether the prevention of clotted dew or a freeze is needed or not at the branch air-supply device can be determined through the temperature of the branch air-supply device and the integral temperature in the running process; the formation of the clotted dew or even the freeze can be prevented through the own running of the branch air-supply device; and the working reliability of the branch air-supply device can be improved.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a method for controlling defrosting of a refrigerator and the refrigerator. Background technique [0002] With the development of society and the continuous improvement of people's living standards, people's pace of life is getting faster and faster, so they are more and more willing to buy a lot of food and put it in the refrigerator. The refrigerator has become one of the indispensable household appliances in people's daily life. . [0003] However, the current air-cooled refrigerators have the following disadvantages: during the defrosting process, the heat generated by the heating device often enters the freezing space, causing the temperature in the freezing space to rise, which is not conducive to the storage of food; in addition, after defrosting the evaporator may It will cause condensation on the parts around the evaporator, and more seriously, it may freeze into ...
