Device and method for rinsing objects in an appliance

摘要

An appliance for washing objects that employs a spray device for delivering a washing fluid, e.g., water, to a wash tub in the appliance. The spray device is configured to reduce consumption of the washing fluid such as during a rinse portion of a washing cycle. In one example, the spray device comprises a plurality of apertures that are arranged in one or more arrays. The apertures are configured to disperse the washing fluid as a plurality of spray streams that form a pair of wetted areas on either side the wash tub. The wetted areas provide wetting of the objects along the sides and extending from a front portion to a back portion of the wash tub.

主权项

1. An appliance, comprising:
a wash zone in which objects to be cleaned are positioned; a wash basket having a top, a bottom, and an outer peripheral wall that bounds and defines the wash zone, the wash basket further comprising a rear portion and a front portion spaced apart from the rear portion; an agitator disposed in and aligned with a center axis of the wash basket, the agitator having a body extending from the bottom of the wash basket and terminating proximate the top of the wash basket; a spray device in a fixed location relative to the wash zone that is above and proximate the rear portion of the wash basket, the spray device comprising,
a body comprising an inlet member and a dispersal member in the form of, respectively, a first hollow tubular structure and a second hollow tubular structure in angular relation to the first hollow tubular structure, the first hollow tubular structure forming an inlet with a central axis that aligns with the center axis of the wash basket, anda plurality of apertures arranged in an array on the second hollow tubular structure of the dispersal member, the array of apertures comprising an aperture on either side of the central axis and in flow communication with the inlet, wherein the array is configured to eject a washing fluid in a spray pattern with spray streams that originate from the plurality of apertures proximate the fixed location and traverse the wash zone to form a first wetted region and a second wetted region on either side of the agitator, and wherein the plurality of apertures comprises at least one aperture disposed on a forward-facing surface of the second hollow tubular structure that configures the at least one aperture to eject the washing fluid in a first spray stream that reaches the front portion of the wash basket.
