Patent number: 9212443Abstract: A pump for pumping water from a bowl of a washing machine is provided. The pump includes a housing coupled to the bowl and a cover with an aperture. The housing and the cover define an interior in fluid communication with the bowl interior via the aperture. A filter filters water entering the interior via the aperture. The filter has a profiled wall defining a volute around the aperture, and a hood disposed above the wall. The profile of the hood perimeter substantially corresponding to the profiled wall to define a profiled space between the perimeter and the profiled wall. The profiled space allows water to enter the volute but substantially prevents elongated objects entering the volute.Type: GrantFiled: September 2, 2010Date of Patent: December 15, 2015Assignee: Fisher & Paykel Appliances LimitedInventors: Jonathan David Harwood, Hugh Griffith Johnson, Geoffrey Alan Lee, Gregory Paul Hill, Anna Kathryn Duncan, Adrian Anthony Sargeant

Publication number: 20090308111Abstract: The invention relates to a laundry appliance with a washing additive dispenser. The laundry appliance comprises a cabinet, a vessel for accommodating laundry, and a motor for rotating the vessel relative to the cabinet. The vessel is rotatably supported within a water tight enclosure. The axis of rotation is substantially horizontal and substantially parallel to a front panel of the cabinet. In an open condition, the cabinet provides access to the vessel via a vessel access area. A washing additive dispenser for dispensing additives to washing fluid contained in the water tight enclosure is positioned so that user access to the dispenser is located in the vessel access area.Type: ApplicationFiled: June 16, 2009Publication date: December 17, 2009Inventors: CHARLES ROBB, ADRIAN ANTHONY SARGEANT

Patent number: 5755244Abstract: A dishwasher having spray arm, motor and pump components configured and mounted so as to occupy very low height. In one form the complete wash system is arranged as a drawer which slides in and out of a cabinet. The cabinet opening is stiffened against racking forces by incorporating an inverse portal frame in the opening flange. A synchronous AC motor is used with the rotor running within the wash chamber driving a wash pump integrated with a rotating spray arm.Type: GrantFiled: January 29, 1997Date of Patent: May 26, 1998Assignee: Fisher & Paykel LimitedInventors: Adrian Anthony Sargeant, William Hugh Currie, Willem Ouwens, Philip John Brace, Robert William Todd, Hans-Joachim Scholz
