Abstract

Abstract A domestic clothes washer has a pair of nested tubs one of which is imperforate to retain the washing fluid, the other of which is perforated an rotatable to centrifuge the washing fluid from clothes being washed therein. A peripheral fill system includes a fill tube circumscribing the top of the nested pair of tubs. The fill tube has transverse rectangular slots to provide a circumferential series of fan-shaped sprays for improved wetting and immersing of the clothes at the start of a clothes washing cycle, for flushing suds from the nested pair of tubs prior to rinsing and for faster release of the tub-adhered clothes during rinse fill. The peripheral fill system includes a vacuum breaker directly connecting a domestic water supply to the fill tube for effecting pressurized sprays to the tubs without back siphoning of washing fluid.
