Abstract
Disclosed is a method of controlling a laundry treating apparatus comprising a tub configured to hold wash water, a drum mounted in the tub, a pulsator mounted in the drum, a sub-drum coupled to the drum, the sub-drum being configured to hold wash water, and a drive unit configured to rotate the drum and the pulsator. The method comprises a water current forming step comprising performing a basket motion and a pulsate motion and a cooling step comprising lowering the temperature of the drive unit. The basket motion is configured to form water current in the wash water held in the tub and in the sub-drum simultaneously. The pulsate motion is configured to form water current in wash water held in the drum while the pulsator is driven. A performance timing of the cooling step is preset in at least one of the wash cycle or the rinse cycle.
