Defrosting method and device for evaporator, refrigerator, computer equipment and storage medium

Abstract

The invention relates to a defrosting method and device for an evaporator, a refrigerator, computer equipment and a storage medium. The method comprises the following steps: obtaining a thickness of afirst frost layer on the surface of the evaporator; detecting whether or not the thickness of the first frost layer is matched with a first preset thickness; while the thickness of the first frost layer is matched with the first preset thickness, obtaining first defrosting power corresponding to a defrosting heater according to the thickness of the first frost layer, starting the defrosting heater, and defrosting with first defrosting power; separately obtaining the thickness of a second frost layer on the surface of the evaporator every preset time; obtaining second defrosting power corresponding to the defrosting heater according to the thickness of the second frost layer, and regulating working power of the defrosting heater as second defrosting power. After defrosting program is started, corresponding defrosting power is obtained according to the thickness, obtained every time, of the frost layer, and defrosting power is smaller than power for maximum power consumption increment,at a defrosting stage, for the current thickness of the frost layer, so that power consumption increment at the defrosting stage is 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
