A drain system for a laundry appliance is provided. The laundry appliance may be configured as a clothes dryer having a heat exchanger to cool and condense moisture-laden air received from the laundry drum. The drain system utilizes a drain structure to catch condensate from the heat exchanger and evacuate the condensate to a sump area. A blower and blower channel moves the dry air from the heat exchanger back to the drum. To prevent negative pressure in the blower channel from moving the condensate to the sump area, an air channel between the blower channel and sump area provides air flow communication.

A cartridge for a laundry appliance includes an outer housing having an interior chamber therein. The outer housing includes a primary axis and a secondary axis that is perpendicular to the primary axis. A pump is contained within the outer housing that selectively delivers a laundry chemistry from the interior chamber to a dispensing outlet of the outer housing. The dispensing outlet is defined within a contoured edge of the outer housing and orients the dispensing outlet at an oblique angle with respect to the primary and secondary axes. A rotational drive is operated by an external actuator. The rotational drive is positioned within the outer housing and in operable communication with the pump. The rotational drive aligns with a drive aperture defined within a wall of the outer housing for receiving the external actuator.

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.

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.

A washer and dryer combination appliance including a housing, a drum positioned in the housing, and a dynamic, expandable seal positioned between the drum and the housing. A laundry compartment inside the drum is accessible through openings in the front of the housing and drum. The drum has a rear wall with perforations that permit air to flow into the laundry compartment. An air gap is located between the rear of the housing and the rear wall of the drum. The dynamic, expandable seal, is actuatable between a retracted position and an extended position. In the extended position, the dynamic, expandable seal extends across the air gap to direct airflow through the perforations in the rear wall of the drum. In the retracted position, the dynamic, expandable seal is spaced away from the drum and therefore does not add any drag on the drum as the drum rotates.

A laundry appliance including an appliance housing, a drum housing positioned in the appliance housing, and a drum that is configured to rotate inside the drum housing. A laundry compartment inside the drum is accessible through openings in the front of the appliance housing, drum housing, and drum. A front appliance door is pivotally connected to a front ring of the drum housing. A water recirculation insert is mounted to the front ring of the drum housing. The water recirculation insert includes a nozzle portion that extends through the front ring to a nozzle opening that is located inside the drum housing and configured to dispense recirculated fluid directly into the laundry compartment.

A lint removal system for a laundry appliance includes a lint washing assembly adapted to deliver wet lint to a disposal area. An impeller is disposed within a continuous processing chamber of a pump casing, the impeller operable to deliver a fluid from the disposal area to a drain outlet. A blade assembly is disposed within the continuous processing chamber, the blade assembly rotationally operable to process the wet lint from the disposal area to define lint particles that are delivered with the fluid to the drain outlet.
