Defrosting control method of refrigerator

Abstract

The invention provides a defrosting control method of a refrigerator. The method comprises the steps of counting total working hours and door opening and closing times of the refrigerator from the last initialization operation of the refrigerator, and obtaining the ambient temperature and the ambient humidity of the refrigerator; obtaining a defrosting starting condition preset by the refrigerator, wherein the defrosting starting condition is that the number of door opening and closing times reaches a threshold of the number of the door opening and closing times, and the threshold of the number of the door opening and closing times is determined according to the total working hours, the ambient humidity and the ambient temperature; judging whether the refrigerator satisfies the defrosting starting condition, and if the refrigerator satisfies the defrosting starting condition, generating a defrosting starting trigger signal is generated. According to the defrosting control method, the threshold of the number of the door opening and closing times is determined according to the ambient humidity, the ambient temperature and the total working hours of the refrigerator, so that a defrosting starting point can be accurately determined according to the parameters of actual ambient conditions such as the ambient humidity, the ambient temperature and the like and working conditions such as the total working hours and the door opening and closing times of the refrigerator, and defrosting can be accurately performed in time according to actual conditions.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a defrosting control method for a refrigerator. Background technique [0002] As far as traditional air-cooled devices are concerned, such as air-cooled refrigerators, defrosting is generally carried out according to a fixed time period. In order to ensure that the frosting thickness of the refrigerator does not affect the refrigeration under harsh conditions, usually the The defrosting cycle is set relatively short, so that the number of defrosting is too frequent for normal use conditions. Since the power of the defrosting heating wire is relatively large, and it will cause the temperature inside the refrigerator to rise, it will cause the power consumption of the refrigerator to increase under normal use conditions. [0003] Therefore, there is an urgent need for a method that can properly perform defrosting according to specific environmental conditions. Contents of ...

[0002] As far as traditional air-cooled devices are concerned, such as air-cooled refrigerators, defrosting is generally carried out according to a fixed time period. In order to ensure that the frosting thickness of the refrigerator does not affect the refrigeration under harsh conditions, usually The defrost cycle is set relatively short, so that the number of defrosts is too frequent for normal use conditions

Due to the high power of the defrosting heating wire, which will cause the temperature in the refrigerator to rise, it will cause the refrigerator to consume more electricity under normal use conditions.
