Patent number: 6454872Abstract: The present invention provides a dishwasher having a wash chamber including a sump. A pump having a rotating element is supported within a pump housing wherein the pump is adapted to draw liquid from the sump through an inlet area and then pump liquid to the wash chamber. A particle chopping assembly is supported in the inlet area upstream of the rotating element, the particle sizing assembly including a particle screen rotatably supporting drive shaft which drivingly supports a chopping blade adjacent the particle screen. The drive shaft has a coupling end which detachably couples to the rotating element. The coupling between the chopping blade and the rotating element is capable of accommodating axial tolerance with regard to the axial position of the rotating element.Type: GrantFiled: April 4, 2000Date of Patent: September 24, 2002Assignee: Whirlpool CorporationInventors: Claude W. Miller, Geoffrey L. Dingler, Todd M. Jozwiak, John A. Miller, Nicholas J. Cottrell

Patent number: 6182674Abstract: A dishwasher is provided having a wash pump and soil collection system. The wash pump may be a volute type pump having a horizontal axis and includes a casing surrounding a wash impeller. The casing has a main outlet and a secondary outlet. The wash impeller draws wash liquid from the dishwasher sump region and pumps the wash liquid through the main outlet and the secondary outlet. The wash liquid pumped through the main outlet is provided to a wash arm device such that wash liquid is recirculated throughout the dishwasher interior wash chamber. The wash liquid pumped through the secondary outlet is directed to flow into a soil collector. The soil collector includes a soil separation channel which receives the flow from the secondary outlet and includes at least one filter screen panel for returning filtered wash liquid back into the sump such that soils are retained in the soil separation channel and accumulate within a soil accumulator region.Type: GrantFiled: June 4, 1999Date of Patent: February 6, 2001Assignee: Whirlpool CorporationInventors: Todd M. Jozwiak, Edward L. Thies, Claude W. Miller, Roger J. Bertsch, Wilbur W. Jarvis

Patent number: 5837151Abstract: A centrifugal soil separator for a dishwasher having a rotating centrifuge connected for rotation with a centrifugal impeller, the centrifugal impeller providing a majority of recirculating wash water for the dishwasher while the centrifuge accepts a second portion of flow and spins that portion of flow for soil separation and to achieve a pumping action to move that quantity of water to the wash water delivery system with the quantity of water moved by the centrifugal impeller. By a coordinated stopping, reversing and starting action of the centrifuge, soil collected therein can be disposed to a soil sizing and drain apparatus for flushing and draining the centrifuge.Type: GrantFiled: April 29, 1997Date of Patent: November 17, 1998Assignee: Whirlpool CorporationInventor: Todd M.
