Abstract
A washing machine comprises an outer tub, an inner tub, a pulsator and a driving means having two rotors, a stator and a deceleration mechanism. One rotor drives the pulsator, and the other rotor drives the inner tub. During washing, the two rotors drive the pulsator and the inner tub to rotate in the same or opposite directions, and during dehydration, the pulsator and the inner tub rotate in the same direction and at the same speed. The automatic washing machine saves on energy consumption, has stable output and has high transmission efficiency.
