Abstract

The invention provides a control method of an air-cooled refrigerator. The air-cooled refrigerator comprises a refrigerating chamber, a refrigerating chamber door, a refrigerating evaporator, a refrigerating draught fan, a temperature sensor used for detecting the temperature of the refrigerating evaporator and a compressor, wherein the refrigerating evaporator and the refrigerating draught fan are used for refrigeration of the refrigerating chamber. The refrigerating evaporator is arranged to be capable of being controlled to communicate with or not communicate with the compressor. The control method comprises the steps that when the refrigerating chamber door is opened under the condition that the refrigerating chamber is in the refrigerating state, the refrigerating draught fan is switched off until the refrigerating chamber door is closed, and the refrigerating evaporator and the compressor are kept communicating with each other until the refrigerating chamber door is closed or until the temperature of the refrigerating evaporator is lower than a first temperature threshold value. According to the control method of the air-cooled refrigerator, the refrigerating draught fan is controlled to be always switched off under the condition that the refrigerating chamber door is opened, so that the situations that due to the fact that the refrigerating chamber door is opened, wet and hot air entering the refrigerating chamber circulates to the refrigerating evaporator, and more wet and hot air is sucked into the refrigerating chamber are avoided, it is avoided that the humidity and / or the temperature in the refrigerating chamber change / changes greatly, and therefore the preservation effect of the air-cooled refrigerator is continuous and stable.

Description

technical field

[0001] The invention relates to the technical field of refrigeration equipment, in particular to a control method for an air-cooled refrigerator. Background technique

[0002] In a traditional dual-system air-cooled refrigerator, when the user opens the door of the refrigerator to take something out, the temperature in the refrigerator will rise. Therefore, after the user closes the door of the refrigerator, the refrigeration system will immediately work and blow air into the refrigerator. A large amount of cold air causes the hot and humid air in the refrigerator to be sucked into the refrigerator air duct, resulting in frosting of the evaporator, and will cause the humidity in the refrigerator to drop, affecting the freshness preservation effect. The above-mentioned problems are alleviated to a certain extent, but the evaporator still frosts quickly, and it needs to start the heating wire to defrost in a short time, which seriously affects the user's use an...
