Abstract: A device for driving a plurality of motors, including an inverter connected to a DC terminal; a multi-phase motor connected to the inverter; and a single-phase motor serially connected to the multi-phase motor, wherein a number of frequency of current input to the multi-phase motor when driving the single-phase motor and the multi-phase motor at the same speed is smaller than the number of frequency of current input to the multi-phase motor when driving the single-phase motor and the multi-phase motor at different speeds. Accordingly, a plurality of motors can be simultaneously driven at different speeds, by using a single inverter.

Abstract: A washing method according to the present invention comprises: a first rotation step for rotating an inner tub; a rotating direction detecting step for detecting the rotating direction of the inner tub; and a second rotation step for starting to rotate the inner tub in the opposite direction to the rotating direction of the inner tub when the rotation of the inner tub stops in the first rotation step. When the inner tub stops over a predetermined time and then restarts, the inner tub starts to rotate in the opposite direction to the rotating direction when the inner tub stops, thereby reducing the eccentricity of the inside of the inner tub, inhibiting collisions between the inner tub and an outer tub, reducing noise during collisions, and improving the rotation performance of the inner tub.
