Problems solved by technology

[0003] like figure 2 As shown, but because the moment the refrigerator door is opened, the power to the fan is immediately cut off, and the fan speed changes from high speed to zero instantly. Due to inertia, braking noise is generated. Secondly, the natural frequency of the fan is close to a certain operating frequency, resulting in resonance (ie Between the speed W and the speed W1), the two kinds of noise are superimposed, which is particularly harsh, which greatly affects the user's sensory experience
In addition, there are some ways to slowly reduce the speed of the fan. Although the brake noise caused by inertia is solved, the noise caused by resonance cannot be reduced or eliminated. When the user opens the refrigerator door, he will still feel a lot of noise. user complaints

Abstract

The invention provides a control method of an air cooling refrigerator. The method comprises the following steps that whether a refrigerator door is opened or not is detected, and when the refrigerator door is opened, whether the current rotating speed of a fan is greater than a first preset rotating speed or not is judged, wherein the first preset rotating speed is greater than the top limit point rotating speed of a resonance region; if so, the fan is controlled to gradually decelerate the current rotating speed to the first preset rotating speed, and in addition, the fan maintains the first preset rotating speed until the refrigerator door is closed. The control method for the air cooling refrigerator according to the embodiment of the invention has the advantages that the noise during the door opening of the refrigerator can be effectively reduced, the user complaining is avoided, and the user experience is improved. The invention also provides a control device of the air cooling refrigerator and the refrigerator.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a control method and device for an air-cooled refrigerator and the air-cooled refrigerator. Background technique [0002] The popularity of air-cooled refrigerators is becoming more and more widespread. Air-cooled refrigerators can not only automatically defrost, but also have uniform air supply and a relatively balanced room temperature. However, due to the existence of fans and air ducts, the refrigerator generates a lot of noise during the cooling process. When the door is opened, the fan continues to run at high speed, and the air ducts are noisy, which affects the user's hearing experience. Therefore, many air-cooled refrigerators are equipped with a door switch, and when the door is opened, the fan stops running, and the noise of the air duct disappears thereupon. [0003] like figure 2 As shown, but because the moment the refrigerator door is opened, the ...
