ABSTRACT:
A clothes washing machine of the vertical axis type has a self-cleaning lint filter integral with the spin tub. The spin tub is formed as a unitary piece from plastic material, and includes a central hub and radially outer bottom wall which are interconnected by a plurality of radially extending ribs. The ribs have spaces between them defining an annular gap, and an annular perforated lint filter is secured in the gap. An oscillating agitator within the spin tub has downwardly projecting vanes on the lower outer surface of its skirt portion which, as the agitator oscillates, cooperate with the spin tub ribs to form a pumping action to pump liquid upwardly through the lint filter and out to the interior of the spin tub. When the agitator and spin tub go into a spin mode, the centrifugal force washes the lint on the underside of the lint filter off into the fluid being pumped to drain.
