Abstract
A domestic clothes washer has an outer imperforate water container to retain the washing fluid and an inner perforate spin tub which is rotatable to centrifuge the washing fluid from clothes being washed therein. A vertically reciprocating agitator in the inner spin tub provides a pulsating toroidal circulation of washing fluid. The spin tub has a perforate generally vertical side wall and an imperforate bottom wall joined thereto by a curved wall portion containing a circumscribing row of holes positioned thereon located so as to carry particulate matter from the spin tub during wash periods while minimizing undesirable back flow through the row of holes during spin periods of the tub.
