Abstract
Disclosed is a washing method in which an inner tub or a pulsator is operated in various ways to achieve reduced abrasion of laundry and enhanced washing performance. The washing machine includes a disentangling washing operation during which the inner tub is alternately rotated in forward and reverse directions to disentangle laundry received in the inner tub, a tapping washing operation, subsequent to the disentangling washing operation, during which the inner tub is successively rotated in a given direction such that the laundry is adhered to an inner surface of the inner tub and the wash water is raised along a path between the outer tub and the inner tub to thereby flow into the inner tub by centrifugal force generated during rotation of the inner tub, and an agitation washing operation, subsequent to the tapping washing operation, during which the pulsator is alternately rotated in forward and reverse directions.
