Abstract

The embodiment of the invention provides a control method of a refrigerator fan and a refrigerator. The control method of the refrigerator draught fan comprises the steps that the draught fan of the refrigerator is controlled to be started; if the feedback signal of the fan is not obtained within the first preset time, the fan is controlled to be restarted; and if the feedback signal of the fan is not obtained within the second preset time, it is determined that the fan is in an abnormal working state. In the fan fault detection, when the feedback signal is not detected within the first preset time, the fan is restarted to improve the starting capability of the fan in bad environments such as stalling and freezing, whether the feedback signal exists or not is detected again after the fan is restarted, the fault state of the current fan can be more accurately judged through two times of detection, and the fault detection efficiency of the fan is improved. Therefore, the situation of false alarm faults of the fan is reduced.

Description

technical field [0001] The present application relates to the field of home appliances, and in particular, to a control method for a refrigerator fan and a refrigerator. Background technique [0002] At present, the proportion of air-cooled refrigerators in the market is increasing. The fan is a key component of the air-cooled refrigerator. If the fan is abnormal, it will have a great impact on the performance of the entire refrigerator. When the fan on the refrigerator runs abnormally, the fault information needs to be reflected on the refrigerator display terminal or mobile phone terminal to remind users or after-sales personnel to carry out targeted maintenance. [0003] However, the fault detection mechanism of the refrigerator for the fan now has the problem of false alarm, which reduces the accuracy of the fault detection result. SUMMARY OF THE INVENTION [0004] The embodiments of the present application provide a control method for a refrigerator fan and a refrige...
