Control method and device for refrigeration fan of refrigerator, and refrigerator

Abstract

The embodiment of the invention provides control method and device for a refrigeration fan of a refrigerator, and the refrigerator, belongs to the technical field of refrigeration, and solves the problems that in the prior art, when a compressor of an air direct-cooling type refrigerator is started up, the temperature of a refrigeration chamber or a freezing chamber is low. The method comprises the steps of when the compressor is started up, judging whether the temperature of the freezing chamber is larger than the shutdown temperature of the freezing chamber or not; when the temperature of the freezing chamber is larger than the shutdown temperature of the freezing chamber, determining a difference value between the temperature of the freezing chamber and the shutdown temperature of the freezing chamber to be a first temperature difference; determining a difference value between the temperature of the refrigeration chamber and the shutdown temperature of the refrigeration chamber to be a second temperature difference; and according to a comparison result between the first temperature difference and the second temperature difference, controlling the start-stop proportion of the refrigeration fan, wherein the start-stop proportion is the proportion of the startup time and the shutdown time of the refrigeration fan within a preset period. The control method and device for the refrigeration fan of the refrigerator provided by the embodiment of the invention are suitable for controlling the refrigeration fan.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a method and device for controlling a refrigeration fan of a refrigerator and a refrigerator. Background technique [0002] At present, for direct air cooling type refrigerators, the compressor is generally controlled to start and stop by the temperature sensor in the refrigerator room. When the temperature measured by the temperature sensor in the refrigerator room is lower than the shutdown temperature of the compressor, the compressor stops. When the temperature is higher than the starting temperature of the compressor, the compressor starts, and the refrigeration fan and the freezing fan are always on when the compressor is started. In this case, the temperature of the refrigerator or freezer is likely to be low. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a method and device for controlling the refrigeratin...
