摘要： A laundry appliance includes a rotating drum for processing laundry. A blower directs process air through an airflow path that includes the rotating drum. A heat exchanger is positioned within the airflow path that dehumidifies the process air. A fixedly-secured lint filter captures lint from the process air at a position upstream of the heat exchanger. A fluid spray system has spray nozzles that deliver fluid to a surface of the fixedly-secured lint filter. Each spray nozzle of the plurality of spray nozzles directs captured lint away from the fixedly-secured lint filter.

摘要： A laundry machine washer-dryer combination includes a cabinet, a drum, a heater, an air duct, a container, and a fluid loop. The cabinet defines an internal chamber. The drum is disposed in the internal chamber and is configured to receive clothing articles. The heater is disposed in the internal chamber and is configured to heat air flowing to the drum during a drying cycle. The air duct is disposed in the internal chamber and is configured direct air from the drum to the heater during the drying cycle. The container is disposed in the internal chamber and has an energy storage material disposed therein. The fluid loop is configured to transfer heat from the air flowing through the air duct to the energy storage material during the drying cycle.

摘要： A fluid flow system for a laundry appliance includes a blower that delivers process air along an airflow path having a heat exchanger. A drain channel receives condensate from the heat exchanger and fluid spray from a spray nozzle for directing lint particles to the drain channel and on to a sump for collecting fluid, including the condensate. A pump seat and a fluid outlet are integrally formed in a sump cover. A pump directs the fluid from the sump to the fluid outlet. A fluid level sensor detects at least minimum and maximum capacities of the fluid in the sump. When the fluid is below the minimum capacity, the pump defines an idle state. When the fluid reaches the minimum capacity, the pump defines an active state. When the fluid exceeds the maximum capacity, the pump directs the fluid to the fluid outlet.

摘要： A mechanism for transferring processed air in an appliance, such as a dryer or washer/dryer combination or the like, between a tub assembly and an exhaust housing has a flexible duct with an inlet end and an outlet end. The inlet end connects to the tub/drum assembly and the outlet end connects to the exhaust housing. A compressing and expanding member is positioned between the inlet end and the outlet end. The mechanism compressing and/or expanding with movement of the tub/drum assembly during washing and/or drying cycles. At least one of the inlet and outlet ends includes a retaining member to secure the duct with the tub/drum assembly or the exhaust housing.

摘要： A combination washer/dryer machine has a rotatable drum inside a cabinet. The drum has an external surface. A tub is positioned inside the cabinet. The drum is rotatable in the tub. The tub has an inner surface. A seal extends between the exterior surface of the drum and the inner surface of the tub forming a desired gap during washing operations and the seal operates to minimize the bypass of drying air during drying operations.

摘要： A household appliance has a cabinet (12) with working operable elements of the appliance (10). A control console (14) for the appliance (10) is associated with the cabinet (12). A human mechanical interface (20), supplying information to an user, is associated with the control console (14). The interface (20) moves with respect to the control console (14) to a desired viewing zone for the user. The interface (20) has a bezel (24) to hold the interface (20). The bezel (24) is rotatable with respect to the console (14). A rotary damper (28) is coupled with bezel (24) rotating the bezel (24). Activation of the rotary damper (28) enables the bezel (24) and interface (20) to rotate to one or more viewing zones.
