Abstract
The washing machine includes an outer tub, an inner tub rotatably provided in the outer tub, a pulsator rotatably provided in the inner tub, a power transmission shaft rotating the pulsator, a buoyancy clutch that moves up and down by buoyancy created by wash water and transfers, when the buoyancy clutch is in a lower position, rotational force from the power transmission shaft to the inner tub to allow the pulsator and the inner tub to rotate integrally with each other, a circulation passage that is provided on an outer portion of the outer tub to allow the wash water drained out of the outer tub to be returned into the outer tub, a pump provided on the circulation passage and a drain guide unit that directs the wash water under the buoyancy clutch to a drain hole of the outer tub so that the buoyancy clutch moves downward.
