Problems solved by technology

[0013] In such conventional documents, since the speed control is performed during the control of the drainage pump motor, there is a disadvantage that the time required for the completion of drainage becomes longer during drainage.
[0014] And, in such prior documents, only the case where speed control is performed at the time of drain pump motor control is disclosed, and no solution is disclosed for noise or vibration generated when the pressure of the vortex chamber of the drain pump rises during dehydration.

Abstract

The present invention relates to a laundry handling apparatus. The laundry handling apparatus, according to one embodiment of the present invention, comprises: an inverter which, by means of a switching operation, converts a direct current power from a converter into an alternating current power, and outputs the converted alternating current power to a drain motor; an output current detection unit which detects an output current flowing in the drain motor; and a control unit which, when the output current flowing in the drain motor is reduced in a state where the speed of the drain motor is at a first speed, controls so that the drain motor rotates at a speed lower than the first speed. Accordingly, the pressure of a swirl chamber of a drain pump may be reduced during spin-drying.
