Patent number: 12195909Abstract: A chemistry dispensing assembly for a laundry appliance includes a reservoir that dispenses a laundry chemistry to a treatment chamber. A mixing channel is positioned below the reservoir that receives the laundry chemistry dispensed from the reservoir. A fluid assembly delivers a fluid carrier through a flow path that includes the mixing channel. The mixing channel is defined between an underside of the reservoir and an upper surface of the mixing channel.Type: GrantFiled: September 6, 2023Date of Patent: January 14, 2025Assignee: Whirlpool CorporationInventors: Christopher A. Hartnett, James Jeffery, Bruno T. Ramasco, Guy M. Kazmierzak

Patent number: 12065366Abstract: Laundry treatment appliances for use in a typical household include a tub that has an opening to provide access to the interior and at least partially defines a treating chamber into which fabric items such as clothes, towels, or linens can be placed to undergo a washing operation. A system can be provided for recirculating wash liquid through the tub to reduce water consumption. At least one tank or reservoir and a coagulant dosing system can be included for the chemical treatment of wash water as part of the wash liquid recirculation system. The tank can also serve to separate coagulated solids from the wash water.Type: GrantFiled: May 25, 2023Date of Patent: August 20, 2024Assignee: Whirlpool CorporationInventors: Mohsin Mahamadshafi Attar, Jalindar S. Dawange, Richard L. Hammond, Christopher A. Hartnett, Peter N. Howes, Eric Monville

Patent number: 11850549Abstract: A dehumidification mechanism for an appliance includes a blower that delivers humid process air along an airflow path. A drum is positioned along the airflow path. A condensing apparatus dehumidifies the humid air to define dehumidified air. A membrane has a plurality of nanopores that define a portion of the airflow path within the condensing apparatus. The humid air is delivered along the membrane having the plurality of nanopores and the nanopores operate through capillary condensation to dehumidify the humid air and separate condensate away from the humid air to define the dehumidified air. The condensate removed by the nanopore membrane is delivered away from the airflow path and to a condensate collection area within the appliance.Type: GrantFiled: August 24, 2022Date of Patent: December 26, 2023Assignee: Whirlpool CorporationInventor: Christopher A Hartnett

Patent number: 11655582Abstract: A laundry appliance includes a cabinet having a rotating drum operably positioned therein for processing fabric. At least one transducer is positioned proximate the drum that provides an ultrasonic resonance that is directed into an interior chamber of the drum. The ultrasonic resonance is adapted to be directed into damp fabric being treated within the interior chamber. The ultrasonic resonance serves to modify water trapped within the damp fabric into a substantially gaseous form.Type: GrantFiled: November 9, 2021Date of Patent: May 23, 2023Assignee: Whirlpool CorporationInventors: Mark J. Christensen, Donald Erickson, Jordan M. Grider, Alexander Halbleib, Christopher A. Hartnett, Christopher A. Jones, K. David McAllister, Rodney M. Welch, Erica L. Roberts
