Evaporator defrosting method, device, refrigerator, computer equipment and storage medium

Abstract

The present invention relates to an evaporator defrosting method, device, refrigerator, computer equipment and storage medium. The method includes acquiring the thickness of a first frost layer on the surface of an evaporator; detecting whether the thickness of the first frost layer matches the first preset thickness; When the thickness of the first frost layer matches the first preset thickness, the first defrosting power corresponding to the defrosting heater is obtained according to the thickness of the first frosting layer, the defrosting heater is turned on, and defrosting is performed with the first defrosting power; The second frost layer thickness on the surface of the evaporator is obtained at each preset time interval; the second defrost power corresponding to the defrost heater is obtained according to the second frost layer thickness, and the working power of the defrost heater is adjusted to the second defrost power. After the defrosting program is started, the corresponding defrosting power is obtained according to the thickness of the frost layer obtained each time, and the defrosting power is less than the power with the largest power consumption increment in the defrosting stage of the current frosting layer thickness, so that the defrosting stage Power consumption increments are reduced.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to an evaporator defrosting method, device, refrigerator, computer equipment and storage medium. Background technique [0002] With the rapid development of the economy and the upgrading of people's consumption and living standards, the demand for home appliances is becoming more and more high-end and intelligent. Air-cooled refrigerators with high-end atmosphere, large capacity and food preservation function have become the new darling of people's modern life. The traditional air-cooled refrigerator makes the temperature in the compartment uniform through its internal air supply system, thereby reducing the freezing situation in the compartment, and thus gradually becomes the mainstream refrigerator. [0003] However, during the use of traditional air-cooled refrigerators, a thick frost layer forms on the surface of the freezing evaporator, which will affect the heat exchang...

Problems solved by technology

[0003] However, during the use of traditional air-cooled refrigerators, a thick frost layer forms on the surface of the freezing evaporator, which will affect the heat exchange efficiency of the evaporator and increase the operating rate of the compressor.

In order to remove the frost layer on the surface of the evaporator, the traditional method is to use a defrosting electric heater to defrost the freezing evaporator of the air-cooled refrigerator regularly, and removing the frost layer on the surface of the freezing evaporator requires a certain amount of additional power consumption, and heating The power of the refrigerator is kept at a fixed power during the defrosting process, so that the power consumption increment during defrosting and defrosting recovery cannot be minimized, that is, the power consumption during defrosting and defrosting recovery is relatively large, so that the function of the refrigerator Increased consumption
