  • Publication number: 20100269866
    Abstract: A wash fluid distribution system for dishwashers includes a spray arm mounted in one of four quadrants of a chamber floor. The spray arms can have lengths that maintain full rotation within their respective quadrant. Spray arms can also have lengths that impinge or overlap into an adjacent quadrant during full rotation of the spray arms. Each spray arm operates with a corresponding, independently controlled wash pump system. Adjacent spray arms can rotate at a same speed in opposing clockwise or counter-clockwise directions. Spray arms can also rotate in different rotation planes. A slanted surface on the chamber floor terminates at a shared particle collection area, which is centered on the chamber floor.

  • Publication number: 20100209084
    Abstract: A heat pump water heater and systems and methods for its control are disclosed. The systems are configured to heat water within a water storage tank of a heat pump water heater wherein a controller within the system is operatively connected to a plurality of heat sources including at least one electric heating element and a heat pump and sensors in order to selectively energize one of the plurality of heat sources. The controller is configure to process data representative of the temperature of water within the tank near the top of the water storage tank, and rate of water flowing out of the water storage tank, in order to automatically selectively energize the heat sources. The selection of heat sources by the controller is determined by a mode of operation selected by the user and the data processed by the controller in view of the selected mode of operation.
