ABSTRACT:
A washing machine with a compound pulsator has a bottom sub-pulsator mounted on the bottom of the washing tub which is revolvable on the revolving shaft, a top sub-pulsator mounted on an upper part of the revolving shaft which is revolvable on the revolving shaft, an intermediate sub-pulsator mounted coaxially with the revolving shaft between the bottom sub-pulsator and the top sub-pulsator which is revolvable on the revolving shaft. The compound pulsator has a revolution controlling part in which the bottom sub-pulsator and the top sub-pulsator are revolved by a predetermined degree simultaneously with revolution of the revolving shaft, and then the intermediate sub-pulsator is engaged with the bottom sub-pulsator and the top sub-pulsator to be revolved therewith. Thereby, the sub-pulsators are alternately revolved in same direction and different directions, so that laundry articles can be prevented from tangling and thus efficiency of washing is largely improved.
