Abstract
An automatic washing machine having a floating member for selectively engaging the inner tub with the rotator or with the outer tub. The outer tub has first teeth on its inner bottom and the inner tub has a through hole on its bottom, and the rotator has second teeth on its lower surface. The drive motor is mounted on the outer bottom center of the outer tub and its output shaft rotatably penetrates the bottom centers of the tubs. The lever having the floating member and a moving tooth on its opposed ends is hinged to a housing between bottoms of the tubs. The selective engagement of the inner tub with the rotator or with the outer tub is achieved by selective engagement of the moving tooth with the second teeth or with the first teeth in accordance with a fluctuating movement of the floating member caused by buoyancy of the washing water in the outer tub. The rotator driving shaft and the motor may be eccentrically mounted on the outer bottom of the outer tub and, in this case, the rotational force is transmitted to the shaft by a transmission belt. The washing machine of this invention thus automatically converts its mode between the washing mode and the dehydrating mode.
