Patent number: 11821124Abstract: 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.Type: GrantFiled: April 26, 2021Date of Patent: November 21, 2023Assignee: Whirlpool CorporationInventors: Michael Vriezema, Arun Rajendran, Logan R. Urbanski

Patent number: 11802360Abstract: 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.Type: GrantFiled: January 23, 2023Date of Patent: October 31, 2023Assignee: Whirlpool CorporationInventors: Gianluca Bocchino, Roy E. Masters, Arun Rajendran
