  • Patent number: 9816221
    Abstract: The present invention relates to a washing machine (7) and pump (8) for a washing machine (7). The pump is driven by a brushless DC motor (38). The pump can be controlled to improve the operation of the washing machine. In one aspect the invention comprises a washing machine (7) with a variable speed pump (8) for pumping out wastewater, a controller (50) for controlling the speed of the pump and a sensor (10) for determining the flow-rate of water being pumped from the washing machine, wherein the controller (50) controls the speed of the pump to maintain the flow-rate at a desirable level.

  • Patent number: 9212443
    Abstract: 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.

  • Publication number: 20090308111
    Abstract: 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.

  • Patent number: 5755244
    Abstract: 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.
