Abstract
A dishwasher having a cabinet and wash chambers in the form of drawers which slide in and out of the cabinet. Rigid and flexible closures are disclosed for sealing off the wash chambers when retracted into the cabinet. A detergent dispenser for the dishwasher is provided in one wall of a wash chamber in the wash water discharge path into the wash chamber so that detergent powder is flushed out of the dispenser and mixed with the wash water prior to the latter being discharged into the wash chamber. A wash program for a dual wash chamber dishwasher is also disclosed which minimizes total water consumption by transferring water from one chamber to the other.
Claims4
A cabinet for a dishwasher having a box configuration with one open side having a top and a bottom and including a recessed kick plate along the bottom of the open side which cabinet provides resistance to racking forces applied parallel to the open side including:
- a top, bottom, two side walls and a back wall of thin sheet material, where each of said top, bottom and two side walls have front edges and each of the two side walls have an upper and a lowermost portion, said walls being joined along their edges to leave a substantially rectangular front opening defined by the front edges of the top, bottom and two side walls,
- the front edge of the bottom wall and the lowermost portions of the side walls being co-planar and recessed back from the front edges of the top wall and the upper portions of the side walls which lie in a second plane,
- internally directed flanges on said front edges,
- said flanges on the bottom and each of the lowermost side edges which are contiguous, are rigidly joined where the bottom and lowermost side edges meet and thereby configured as an inverted tapered beam portal frame with said two corners forming moment resisting joints,
- rigid link members coupling the flanges on the lower recessed portions of the side walls to said flanges on the upper portions of the side walls each having a top and a bottom and the flange on the top edge forming a beam linking each of the tops of the flanges on the upper portions of the side walls, the two joints defined by the intersections of the beam with the portal frame having no substantial resistance to bending moments.
