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.

A combination washing and drying machine including a chassis defining a chassis interior and a chassis opening, a tub located within the chassis interior and defining a access opening, a drying air circuit, a wash liquid circuit, a closure selectively movable relative to the chassis between an opened position, where the access opening is accessible, and a closed position, where the access opening is inaccessible, a fluid seal, and a thermal seal. The fluid seal configured to seal the tub relative to the closure when the closure is in the closed position. The thermal seal configured to seal the closure relative to the chassis when in the closed position.

The present invention discloses a clothes dryer or washer-dryer. The clothes dryer or washer-dryer includes: a cabinet; an inner drum rotatably disposed in the cabinet and having an air inlet and an air outlet; and a heat pump module disposed to an upper end of the cabinet and including: a casing connected with the cabinet and defining a heat exchange chamber and at least one mounting chamber therein, the heat exchange chamber having a heat exchange inlet and a heat exchange outlet; a condenser disposed in the heat exchange chamber; a compressor disposed to the casing; an evaporator disposed to the casing; a throttling device disposed to the casing and sequentially connected with the condenser, the compressor and the evaporator to form a heat pump circuit; and a fan assembly disposed to the casing and having an inlet and an outlet, the inlet communicating with the heat exchange outlet, and the outlet communicating with the air inlet, wherein at least one of the compressor, the evaporator, the throttling device and the fan assembly is disposed in the corresponding at least one mounting chamber. The clothes dryer or washer-dryer with the heat pump module integrally mounted to the cabinet is reasonable in component layout and stable in component installation.
