Abstract: A drying appliance includes a cabinet. A blower directs process air through a closed-loop airflow path and through a processing chamber and a condensing unit. The condensing unit is attached to an external surface of the cabinet. An open airflow path directs ambient air through the condensing unit and to an area exterior to the cabinet. The ambient air remains separated from the closed-loop airflow path. The condensing unit is configured to exchange heat between the process air within the closed-loop airflow path and the ambient air moved through the open airflow path. The ambient air cools and dehumidifies the process air to form condensate on an interior surface of the condensing unit.

Abstract: 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 both washing and drying operations and minimizing bypass of drying air during the drying operation.

Abstract: 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.

Abstract: A door assembly for selectively opening and closing an access opening to a treating chamber of a laundry treating appliance includes an inner door wall and an outer door wall adjacent to the inner door wall, wherein the outer door wall and the inner door wall at least partially define an internal volume. The inner door wall includes a portion that is configured to extend at least partially into the treating chamber when the door is closed, and includes an air inlet and an air outlet. The door assembly is configured such that the internal volume is in fluid communication with an airflow inside the treating chamber when the door assembly is closed.

Abstract: A laundry appliance includes a drum for processing laundry. A blower delivers process air through an airflow path that includes the drum. A lint filter is positioned within the airflow path that separates particulate matter from the process air to define entrapped lint particles. A lint disposal mechanism removes the entrapped lint particles from a surface of the lint filter to define removed lint. A holding compartment receives the removed lint for disposal.
