Abstract
The invention discloses a method for automatically removing dust of a cooler fan. The method comprises the following steps: S1, driving blades of the cooler fan to rotate in a first direction by a fan motor at a first frequency in a first time interval; S2, driving the blades of the cooler fan to rotate in a second direction by the fan motor at a second frequency in a second time interval, wherein the second time interval is a secondary time interval of the first time interval; the second direction is opposite to the first direction; the second frequency is higher than the first frequency. According to the method, the rotation frequency and the rotation direction of the fan are controlled; the removed dust separates from the fan blades by means of self wind power of the fan blades by using inertia under the action of positive rotation and reverse rotation of the fan blades; especially, a method for reversely blowing twice is adopted; the running frequency of the fan motor is gradually increased in the reverse blowing stage, so that the wind power of the cooler fan is enhanced instantly in the reverse blooding stage.
