Abstract: A spraying device for a washing machine includes a body including a wall having an outer surface, a water inlet and a channel defined therein. The channel is in flow communication with the water inlet, and a plurality of nozzles extend through the wall and in flow communication with the channel. The washing machine includes a wash tub and a basket mounted within the wash tub. The basket is configured to rotate. The nozzles include an inlet, an outlet, an inner diameter, and an outer diameter. At least a portion of the outlet includes a surface substantially perpendicular to a flow of water through the nozzle, and the nozzles have a length longer than a thickness of the wall. At least a portion of the outlet is unitary with the wall outer surface.

Abstract: A washing machine including a tub, a basket rotatably mounted within the tub, and a spraying ring disposed at a top portion of the tub, and including a plurality of nozzles arranged in groups, the nozzles separated by a first distance, the groups separated by a second distance different than the first distance; wherein each of the plurality of nozzles has an opening therein, the openings of the plurality of nozzles of the same group are parallel to each other, and the spray ring is configured to direct water into the tub through the openings.
