  • Patent number: 7832419
    Abstract: A dishwasher includes a cabinet and a wash system slidably mounted within the cabinet in such a manner that it may be withdrawn horizontally out of the cabinet for loading with dishes. The wash system includes an open top wash chamber having a floor and side walls adapted to accommodate dishes within which wash liquid is sprayed. Two rotating spray arms are mounted in the bottom of the chamber for producing a spray of wash liquid within the chamber. A wash pump for pressurizing wash liquid discharges into a manifold located on the floor of the chamber. The spray arms receive wash liquid from the manifold. A drain pump evacuates wash liquid from said chamber. A wash chamber closure is mounted in the top of the cabinet. The closure engages with the wash chamber opening to sealably close off the wash chamber on its retraction into the cabinet.

  • Patent number: 5822812
    Abstract: The invention relates to an improved remotely operated plug assembly (13) of the type with a pop-up plug (13) and cabling (14), wherein the inter-engaging means and the means for retaining the plug (13) in the sink waste unit (11) and in the closed position are circumferential. This allows the free movement of fluid from the plug (13) to the sink waste unit (11). The improvement relates to the use of common elements for both the inter-engaging means and the retaining means so that the one movable pin (34) acts in both the inter-engagement of the plug (13) and the sink waste unit (11), and the retention of the plug (13) within the sink waste unit (11) and in the closed position.
