Abstract
An automatic washing machine and a method for confirmation of a washing machine clutching operation which achieves the desired mode conversion between a washing mode and a dehydrating mode by ascending and descending its inner tub. The washing machine includes an outer tub, a perforated movable inner tub, a buoyancy generator for lifting the inner tub in accordance with a water level in the outer tub, a motor mounted on the outer bottom center of the outer tub, a rotator mounted on a top end of the motor shaft, and a clutching unit for selectively coupling the inner tub to either the outer tub or the rotator according to the position of the inner tub ascending and descending under the guide of the motor shaft. To confirm the clutching operation, a driving time or a driving stop time of the motor is counted and compared with a predetermined reference time.
