1. A method for determining a blockage of a filter of a clothes dryer, wherein the clothes dryer comprises a motor, and the method comprises:
acquiring an actual rotational speed of the motor, and determining an electrical parameter corresponding to a rotational speed range as a first threshold corresponding to the actual rotational speed, wherein the actual rotational speed belongs to the rotational speed range;
acquiring an actual clothes volume in the clothes dryer, and correcting the first threshold according to a correction coefficient corresponding to a clothes volume range to obtain a second threshold, wherein the actual clothes volume belongs to clothes volume range; and
acquiring an actual electrical parameter of the motor, and in response to detecting that the actual electrical parameter is less than the second threshold, determining that the filter of the clothes dryer is blocked.
