  • Patent number: 5878600
    Abstract: A clothes washing machine includes a spin-dry tub and an oscillatory agitator disposed at the bottom of the tub. The agitator includes a centrally located vertical hole in which an axial fan is mounted. A drive mechanism oscillates the axial fan relative to the agitator about a vertical axis to generate an upward water jet that disperses the laundry in a manner preventing entwinement and entanglement thereof. The driving mechanism comprises a roller mounted on an underside of the agitator. The roller engages the bottom of the tub and is oscillated by frictional contact therewith during oscillation of the agitator. Oscillation of the roller is transmitted to the axial fan by a flexible shaft.
