Refrigerator defrosting control method

Abstract

The invention provides a defrosting control method of a refrigerator, comprising: counting the cumulative working time and the number of times of opening and closing of the refrigerator since the last initialization operation of the refrigerator, and obtaining the ambient temperature and humidity of the refrigerator; obtaining the preset defrosting time of the refrigerator Start conditions, defrost start conditions include: the number of door opening and closing times reaches the threshold of door opening and closing times, and the threshold of door opening and closing times is determined according to the cumulative working time, ambient humidity and ambient temperature; judging whether the refrigerator meets the defrosting start conditions, if the refrigerator meets the defrosting start conditions condition, generate a trigger signal to start defrosting. The defrosting control method of the present invention determines the door opening and closing times threshold according to the ambient humidity, ambient temperature, and cumulative working hours of the refrigerator, and can work according to the actual environmental conditions such as the ambient humidity and ambient temperature of the refrigerator, the cumulative working hours, and the number of times of door opening and closing. State and other parameters to accurately determine the starting point of defrosting, which can more accurately correspond to the actual situation to defrost in time.

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.
