Abstract
A control method of a washing machine is capable of safely achieving a tub washing operation control with low power consumption. At the time of performing tub washing, water of which the amount is decided depending on a volume inside a drum and a volume inside a water tub is supplied to the water tub, and the rotation speed of the drum is controlled to be inversely proportional to the volume of the supplied water, thereby efficiently controlling a tub washing operation with low power consumption. Also, the rotation state of the drum is controlled, at the time of performing the tub washing, to maintain the temperature of a motor or a printed circuit board (PCB) to be a predetermined level or less, thereby safely controlling a tub washing operation with low power consumption. In addition, it is determined whether the revolutions per minute (RPM) of the drum rotating at the tub washing operation belong to a resonance band, and the RPM are controlled such that the RPM deviate from the resonance band, thereby achieving a tub washing operation procedure with small noise and vibration.
