A washing machine including a washing tub and a bowl-shaped agitator which is rotatably disposed in the lower part of the washing tub. The washing tub includes a ring-shaped frame element, which covers the gap between the bowl-shaped agitator and the inner surface of the washing tub, whose internal diameter is the same as that of the bowl-shaped agitator.

Washing machine having rotary basket in washing tub

A washing machine having an improved pulsator which includes a skirt, vanes projecting from the skirt, and a shaped projection having a planar surface located eccentrically from the center of rotation of the skirt and extended to a position higher than the vanes. The pulsator rotates in the forward and reverse directions to responsively effect eccentric motion of the projection about the central axis of rotation so that highly turbulent localized water flow is established in conjunction with a vortex flow arrangement to enhance the washing capabilities of the machine.

Washing machine

Disclosed is a washing apparatus having a spinnable tub for receiving a liquid together with materials to be washed and for discharging the liquid therein through its upper portion by a pumping action caused by centrifugal forces, a pulsator disposed in the spinnable tub on the bottom thereof at an eccentric position with respect to the axis of the rotation of the spinnable tub, and resistive means located in the spinnable tub at a region substantially diametrically opposite to the pulsator, whereby resistance to the liquid rotating in the spinnable tub caused by the pulsator and the resistive means is balanced with respect to the axis of rotation of the spinnable tub.
