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.

A drum washing machine, which decelerates rotation of a driving motor through a planetary gear mechanism and transfers the rotation to the drum, so that the drum and a rotating body with a projection rotate at different rotating speeds. The planetary gear mechanism includes a sun gear, an internal gear, a plurality of planetary gears, planetary gear carrier. The planetary gear carrier has a rear planetary carrier and a front planetary carrier, through which the planetary gears are clamped from both sides thereof, supporting shafts erected between the front and the rear planetary carrier, the planetary gears are rotatably provided on the supporting shafts. Base ends of the supporting shafts are fixed on the rear planetary carrier before the planetary gears being provided on the supporting shafts The front planetary carrier is fixed at front ends of the supporting shafts provided with the planetary gears.
