  • Patent number: 5671617
    Abstract: A clothes washer includes a laundry tub assembly disposed within a stationary main water tub. The laundry tub assembly includes outer and inner tubs rigidly attached together and radially spaced apart to form therebetween a space having a lower water inlet and an upper water outlet. A pulsator is disposed within the tub assembly to agitate clothes during a washing operation. The pulsator oscillates about a vertical axis and thereby produces streams of water traveling upwardly through the space and from the outlet to fall onto clothes being washed, in order to push the clothes downwardly. Spirally arranged members are disposed within the space to impart a swirling motion to the water traveling therethrough, so that the water discharged from the water outlet travels in generally the same direction as the direction of rotation of the pulsator and thus in the same direction as the clothes.
