ABSTRACT:
An outer pulsator mounted on a bottom of a washing tub has a hollow protruding part protruded upwardly at a center thereof and a bottom plate extended radially from a lower skirt of the protruding part. An inner pulsator is installed inside of the protruding part. A gear part has an inner gear formed under the inner pulsator, an internal gear formed under the outer pulsator, and an intermediate gear engaged between the inner gear and the internal gear. When the inner gear is rotated by the driving motor, the internal gear is rotated in a reverse direction to a rotating direction of the inner gear by intermediate gear therebetween. A current generated by the inner pulsator goes through communication holes of the protruding part of the outer pulsator and then breaks a reverse current generated by the outer pulsator, so that laundry articles are prevented from tangling and twisting. Therefore, laundry articles are washed by being beaten with random and irregular water currents without damage.
