Abstract: A radio frequency (RF) laundry dryer includes, amongst other things, an RF generator, a drying surface and a Faraday cage enclosing the drying surface. The drying surface on which textiles are supported further includes an RF applicator having an anode and cathode coupled to the RF generator. At least a portion of the cathode substantially encompasses the anode to electrically shield the anode from the Faraday cage ensuring the formation of an e-field between the anode and cathode instead of the anode and the Faraday cage upon energizing the RF generator.

Abstract: 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.

Abstract: A laundry appliance including an appliance housing, a wash unit tub disposed inside the appliance housing, a drum rotatably supported within the wash unit tub, and a wash water dispenser assembly. A laundry compartment is provided inside the drum and the drum is rotatable about a drum axis. The wash water dispenser assembly includes a dispenser hose and a mating interface assembly. The dispenser hose includes a dispenser hose inlet and a dispenser hose outlet. The mating interface assembly connects the dispenser hose outlet to the wash unit tub. The mating interface assembly includes a tub port adapter on the tub sidewall that extends outwardly away from the drum axis to provide a mechanical connection with the dispenser hose outlet.

Abstract: 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.

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.
