  • Patent number: 5383724
    Abstract: The present invention relates to an assembly for mounting an outer or external panel to a door for a mid-sized built in dishwasher. A treatment chamber access opening is normally covered by a dishwasher door (17) which is pivotally supported at its lower horizontal edge for movement from a vertical, closed position to a horizontal, open position. The dishwasher door (17) includes an outer door (18) with a panel whose peripheral parts (19) facing the treatment chamber are placed adjacent a front edge (20) of a cabinet shell surrounding the chassis (21) when the dishwasher door is in its closed position. During movement of the dishwasher door from the closed to the open positions, a lower edge of the outer door (18) is always positioned in front of a vertical plane defined by the front edges (20) of the cabinet shell, allowing the outer door to move without interference from the surrounding cabinetry.

  • Patent number: 5143306
    Abstract: A device for a dishwasher includes a tub (10) in which liquid, by means of a circulation pump (17) and at least one rotating wash arm (11), is sprayed onto the dishes. The liquid is collected at the bottom (13) of the tub and discharged by a drain pump (21). The bottom (13) is provided with a coarse grating (42) for collecting food waste dislodged from the dishes. The device comprises a rotating and cutting means (44) cooperating with the grating (42) for disintegrating the waste on the grating so that the disintegrated waste falls down into a container (43) which is in communication with the inlet of the drain pump (21).
