Patent number: 11668040Abstract: A laundry appliance includes a rotating drum that receives laundry to be treated. A motor rotates a drive shaft about a vertical axis and engages the rotating drum at a base. A coupler is disposed within an upper portion of the base and that rests upon the drive shaft to transfer rotational forces from the drive shaft to the drum. A lower portion of the base engages an outer surface of the shaft to resist moment forces that are exerted against the drive shaft in an off-axis direction relative to the vertical axis.Type: GrantFiled: November 24, 2020Date of Patent: June 6, 2023Assignee: Whirlpool CorporationInventors: Nicholas C. Fugal, Bradley D. Morrow, Joseph C. O'Connor, Prabhath KV, Jason S. Sabel, Christine L. Strain, Meredith A. Wagner, Robert C. Williams

Patent number: 11629450Abstract: A laundry appliance includes a drum that is rotationally operable within a wash tub. A chemistry receptacle is located proximate the drum. A chemistry dispensing module is coupled to the chemistry receptacle and has a prewash portion and a main wash portion. A first fluid inlet is coupled with the prewash portion and a second fluid inlet is coupled to the main wash portion. An outlet extends from the chemistry dispensing module to a laundry treating chamber. A prewash nozzle is coupled to the first fluid inlet and the prewash portion. The prewash nozzle includes an elongated arcuate body that follows a curvature of the prewash portion and defines a cyclonic flow path from the prewash nozzle to the outlet.Type: GrantFiled: December 28, 2021Date of Patent: April 18, 2023Assignee: Whirlpool CorporationInventors: Vinayak A.
