ABSTRACT:
A washing machine with sub-pulsators is disclosed. A pulsator for generating vortical water flow is installed at a bottom of a washing tub, and many sub-pulsators are mounted on an inner side wall of the washing tub. Many ducts for forming passages in a vertical direction are provided in the side wall of the washing tub. When the pulsator is rotated, washing water flows in the ducts by the centrifugal force thereof and moves up along the ducts. The sub-pulsator is rotated by the washing water flowing in the ducts. Thus, a complex water flow is generated by the pulsator and the sub-pulsator, so the washing effect is improved and the twisting and tangling of the laundry is diminished.
