  • Patent number: 8808466
    Abstract: In a dishwasher having a washing chamber capable of accommodating kitchenware for washing, a detergent dispenser includes a housing defining a chamber for receiving detergent. A lid is pivotally connected to the housing for selectively pivoting between a closed position for sealing the detergent chamber and an open position which permits washing fluid to enter the detergent chamber in connection with dispensing of detergent. The detergent chamber is provided with at least one washout port enabling washing fluid to enter the chamber, even if the lid can only pivot through a limited range to a partial open position due to an obstruction. A raised shield guard, which is spaced from the lid, extends in front of the lid to ensure that a potentially obstructing object within the washing chamber does not prevent the lid from moving to at least the partial open position during a wash cycle.

  • Patent number: 8282741
    Abstract: A sequencing spray arm assembly includes a plurality fluid spray arms rotatably mounted on respective radially spaced carrier arms. The rotating fluid spray arms are in fluid communication with a fluid distribution manifold and adapted to distribute washing fluid throughout a washing chamber of the appliance. A sequencing diverter valve system enables delivery of washing fluid from the fluid distribution manifold to one or more of the plurality of rotating fluid spray arms. A fluid responsive rotating drive arm drives the rotation of a sequencing disk in the valve system between discrete positions and enables delivery of fluid to one or more of the plurality of rotating fluid spray arms in a sequential manner such that, for each discrete position, less than the total number of spray arms are supplied with washing fluid at a time.
