Patent number: 11375872Abstract: A dishwasher for treating dishes according to an automatic cycle of operation includes a tub at least partially defining a treating chamber with an access opening, a sump fluidly coupled to the tub, and a liquid recirculation circuit fluidly coupling the sump to the treating chamber. The liquid recirculation circuit includes at least one rotating spray tube having a longitudinal body axis defining a rotational axis. The at least one rotating spray tube comprises a hollow tube having first and second opposing ends with the first end fluidly coupled to the liquid recirculation circuit and the second end comprising a drain valve. The hollow tube has a single wall and a longitudinal body axis defining a rotational axis and plurality of spray nozzles are arranged about the longitudinal body axis on an exterior of the single wall.Type: GrantFiled: July 9, 2020Date of Patent: July 5, 2022Assignee: Whirlpool CorporationInventors: Frederick T. Roderick, Antony M. Rappette, Daniel Lottinville, David Brightbill, Matthew Jaske, Rodney Welch, Michael Lagness

Patent number: 10959596Abstract: A dishwasher having a tub and spray arm assembly for a dishwasher having a spray arm assembly for spraying wash liquid in the tub. The spray arm assembly has spray arm inlet, a bearing assembly with a bearing body that defines a through passage with a bearing inlet and a bearing outlet fluidly coupled to the spray arm inlet. The spray arm assembly also has a liquid supply conduit with a supply outlet fluidly coupled to the bearing inlet, a seal positioned between the bearing body and the liquid supply conduit; and a deflector provided within the supply outlet to effectively divide the supply outlet into at least two portions. At least one of the two portions faces upstream and defining an effective cross-sectional area confronting the bearing inlet that is less than or equal to the cross-sectional area of the bearing inlet. The deflector is also aligned with the bearing inlet and defines a turn in the supply outlet for directing liquid into the bearing inlet.Type: GrantFiled: May 1, 2020Date of Patent: March 30, 2021Assignee: Whirlpool CorporationInventors: Mark S. Feddema, Blair D. Mikkelsen, John A. Miller, Kevin Miller, Alvaro Vallejo Noriega, Antony M. Rappette, Frederick T. Roderick, Pritish Roy
