A drain pump is provided that may include a pump motor; an impeller connected to a rotational shaft of the pump motor. The impeller may include a circular hub, an impeller shaft that extends from a center of a lower surface of the hub, and a plurality of blades that extends from an outer circumferential surface of the impeller shaft and the lower surface of the hub in a radial direction of the hub. The hub may have a longitudinal cross section in which a thickness of the hub gradually increases from the center of the lower surface toward an edge thereof.

The present disclosure relates to a heat pump based dryer or a combination washer and dryer device comprising a housing receiving a drum for containing associated articles to be dried by air that flows along a pathway between an outlet and an inlet of the housing. A fluid is provided in the pathway to at least partially remove moisture from the air. A heat pump includes a heat source located at least partially within the pathway and a heat sink being operatively adapted to the heat source to circulate a refrigerant therein. An enclosure at least partially containing the heat sink is arranged to accept the fluid from the pathway to exchange heat with the heat sink and return the fluid to the pathway. Fluid may be provided to the pathway by a spray nozzle adjacent the outlet or by an evaporative media downstream of a lint separator.
