WASHING MACHINE Russian patent published in 1994 - IPC

FIELD: home appliance washing machine. SUBSTANCE: machine has a tub and a pump. A delivery line of the pump is connected to a perforated cylinder which is coaxially mounted in the tub, and the intake duct of the pump is connected to the tub drain opening. A hollow disk is attached to the cylinder. Two or more outlet ducts are pivotally mounted on the disk periphery for effecting a jet torque moment. On the cylindrical surface of the cylinder perforations are formed, being arranged in a spiral path, each perforation having an axis alternatively inclined up and down relative to its horizontal plane. The pivotally mounted ducts make it possible to change the direction and the speed of rotation of the washing solution by reversing the jets which are effecting the jet torque moment. EFFECT: enhanced washing efficiency. 2 cl, 3 dwg
