Abstract: A washing appliance includes a drum that is rotationally operable within a tub about a vertical rotational axis. An impeller is positioned within a lower portion of the drum and is rotationally operable about the vertical rotational axis. The impeller includes a plurality of flow channels that extend below the impeller and between the impeller and the tub. A receiver is positioned at a top of the impeller and includes apertures that are in communication with the respective flow channels. A filtering cap is disposed on a top of the receiver and positioned within a medial horizontal level of the tub. The filtering cap includes inlets that direct a toroidal flow into a removable particulate chamber positioned within the filtering cap. The toroidal flow is further directed through the respective flow channels to continue through the toroidal flow within the drum.

Abstract: A washing appliance includes a tub positioned within an outer cabinet. A rotating drum rotates within the tub. A fluid flow path directs fluid through the tub and the drum. A rotator selectively rotates relative to the drum to generate at least a toroidal flow of the wash fluid through the drum and a supplemental flow of the wash fluid through a filter assembly positioned within the rotator.

Abstract: A washing appliance includes a drum that is rotationally operable within the tub about a vertical rotational axis. An impeller is positioned within a lower portion of the drum and is rotationally operable about the vertical rotational axis. The impeller includes a plurality of external vanes and a plurality of channel ribs that cooperate to promote a toroidal flow of wash fluid within the drum. A filtering cap is disposed on a top portion of the impeller and has a plurality of inlets that direct the toroidal flow of the wash fluid into a filtering chamber positioned within the filtering cap. The toroidal flow of the wash fluid continues through the filtering chamber and beneath an underside of the impeller, wherein the filtering chamber separates particulate matter from the toroidal flow of the wash fluid.
