Abstract

Abstract A water inlet device for an automatic clothes washer is provided which provides a flow of water against an interior surface of a wash basket and onto a clothes load within the basket through a wide range of inlet water pressures while preventing excessive splashing against the basket wall at high water pressures. The inlet device has a downwardly angled front wall which redirects the inlet water into the wash basket, and the wall has a varying downward angle along its length to provide the automatic pressure compensation. A central portion of the lip is angled downwardly toward the basket wall and the lateral edges are angled downwardly away from the basket wall such that at normal water pressures most of the inlet water is directed at the central portion, and thus toward the basket wall, and at higher pressures more water is directed toward the lateral edges which direct the excess water away from the basket wall and directly onto the clothes load.
