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 liquid-cooled condenser for use within a laundry treating appliance for treating laundry according to an automatic cycle of operation includes an air flow passage. The air flow passage is fluidly coupled with an air recirculation circuit. A plurality of fins is spaced from the air flow passage. The liquid-cooled condenser also includes a liquid flow passage.

A drum for a combination washer dryer can include a plurality of sections. The sections can be interconnected by a plurality of flexible gaskets. The drum can be configured to expand and contract radially. The drum can radially expand to dry wet laundry during a drying phase following a washing phase in which laundry is washed.

A heat pump module for a laundry treatment device and the laundry treatment device are provided. The heat pump module includes a base plate, a top cover and a compressor.

For the heat pump module according to the present invention, the extension line of the axis of the compressor intersects with the first side wall and the second side wall, which facilitates the layout of leads and pipes connected with the compressor and the arrangement of other components on the base plate, thereby improving utilization rate of installation space on the base plate and optimizing the layout scheme of the heat pump module.

A heat pump system, and a drier or washer-drier having the same are provided. The heat pump system includes a base, a horizontal compressor and a damper, in which the horizontal compressor is mounted to the base; the damper is supported on the base and supports the horizontal compressor; at least two dampers are arranged along an axial direction of the horizontal compressor. According to the present invention, vibration and noise of the heat pump system may be reduced effectively, and the overall service life thereof may be improved.

A heat pump mounting box for a heat pump drier or washer-drier, and a heat pump drier or washer-drier having the same are provided. The heat pump mounting box includes a base provided with an air suction port, a two-device mounting chamber, a fan mounting chamber, and a fan air inlet for communicating the two-device mounting chamber and the fan mounting chamber; an air passage guide plate mounted to the base and defining, together with the base, an air guide passage that has a drying air inlet in communication with the air suction port and a drying air outlet in communication with the two-device mounting chamber; an air guide wall disposed in the two-device mounting chamber and opposite the drying air outlet; and a cover plate mounted over the base and at least covering the two-device mounting chamber. The heat pump mounting box according to the present invention has a high utilization rate of the drying air and a good drying performance.

A laundry treatment device and a heat pump module thereof are provided. The laundry treatment device includes a cabinet, a tub component and a heat pump module. The cabinet defines a front side and a top side, an opening is formed at the front side. The tub component is disposed in the cabinet, and defines an open end opposite to the opening. The heat pump module is disposed at the top side of the cabinet in an overhead manner, and includes a compressor imbedded in the cabinet in a sunken manner.

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.

A heat pump mounting box for a heat pump drier or washer-drier machine and a heat pump drier or washer-drier machine having the same are provided. The heat pump mounting box includes: a base provided with an air suction port, a two-device mounting chamber, a compressor mounting chamber, a cooling air supplement port for communicating the compressor mounting chamber with the outside, and a bypass orifice for communicating the two-device mounting chamber with the compressor mounting chamber; an air passage guide plate mounted to the base and defining, together with the base, an air guide passage that has a drying air inlet in communication with the air suction port and a drying air outlet in communication with the two-device mounting chamber; and a cover plate mounted over the base and at least covering the two-device mounting chamber. The heat pump mounting box according to the present invention has a function of supplying cooling air, so as to improve the clothes drying performance of the heat pump drier or washer-drier machine.

A heat pump drying or washing-drying machine is provided. The heat pump drying or washing-drying machine includes a heat pump module, and the heat pump module includes a soft-flock filtering mesh assembly having a first support frame and a second support frame which are used for mounting the soft-flock filtering mesh, and the second support frame is disposed to the first support frame, so that the soft-flock filtering mesh assembly is capable of being mounted and dismounted as a whole.
