WASHING MACHINE DRIVING DEVICE, WASHING MACHINE HAVING SAME, AND WASHING MACHINE DRIVING METHOD

WIPO Patent Application WO/2017/200329

A1

The present invention relates to a washing machine driving device, a washing machine having the same, and a washing machine driving method, wherein energy consumption can be minimized when washing water streams are formed in opposite directions by driving a pulsator and a washing tub in opposite directions in order to form a powerful three-dimensional washing water stream having a high degree of cleaning action. The washing machine driving device comprises: a double rotor/double stator type driving motor having an inner rotor and an outer rotor that can be independently controlled by double stators; an inner shaft for transferring an outer rotor output to the pulsator; an outer shaft for transferring an inner rotor output to the washing tub; and a control unit for controlling the inner rotor and the outer rotor, wherein the control unit has a time of stop when the pulsator switches the direction of rotation to clockwise and counterclockwise directions during a washing stroke, and the washing tub is controlled to be activated before the time of driving of the pulsator in the clockwise and counterclockwise directions ends such that driving occurs in the opposite direction to the direction of rotation of the pulsator.
