Abstract: Selecting cycle modifiers for a clothes dryer is provided. Responsive to a requested cycle of operation for drying a load and a previous cycle being the same cycle type, and further responsive to historical information for the previous cycle indicating positive user feedback that dryness of the load was correct, cycle modifiers corresponding to the requested cycle are applied, and the clothes dryer is operated without soliciting further user feedback. Responsive to the requested cycle and the previous cycle being different cycle types, or responsive to the historical information for the previous cycle indicating negative user feedback that the dryness of the load was incorrect, apply the cycle modifiers corresponding to the requested cycle, operate the clothes dryer, and solicit further user feedback with respect to the cycle of operation of the clothes dryer to update cycle modifiers for use in future cycles of the same cycle of operation.

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: An air purification system is provided. A visor portion is configured to secure to a head of a user and maintain a field of vision for the user. An air delivery portion is configured to draw in air from an external environment. A disposable barrier hood is configured to cover at least the visor portion. The visor portion defines a breathing outlet to exhaust the drawn-in air in proximity to a breathing area for consumption by the user. The disposable barrier hood fluidly isolates the breathing area from the external environment.

Abstract: A combination washer and dryer appliance includes a cabinet, a drum housing and a drum with a drum wall that defines a laundry compartment. A drying air circulation path extends from an inlet positioned a drum wall to an outlet positioned in fluid communication with the laundry compartment. A filter coil is disposed adjacent to the drying air inlet. A condensing system includes the filter coil located on the drum wall at the drying air inlet and a second coil located in the cabinet and outside of the drying air circulation path. The filter coil and second coil are arranged in fluid communication and containing a heat-transfer fluid such that the filter coil acts as both a lint filter. A condenser dehumidifies drying air entering the drying air inlet and such that the second coil acts as a heat exchanger for transferring heat to ambient air located inside the cabinet.

Abstract: A seal for a tub/drum assembly has a ring body to secure the seal to the tub/drum assembly. An arm extends from the ring body. The arm reduces a gap between the tub and drum. A mass at an end of the arm. The mass enables the arm to deflect at high drum rotational speeds increasing the gap between the tub and drum during high rotational speed of the drum. Alternatively, the arm is of a material prohibiting substantial deflection so that the gap is maintained at all speeds between the tub and drum without the arm contacting the drum creating high resistance in an airflow path.
