  • Patent number: 6684441
    Abstract: The invention provides a method for the washing of items of laundry (11), in which only the items of laundry (11) are transferred from the last washing chamber (18) into the first rinsing chamber (19), without the washing liquid. As a result, the washing liquid cannot pass into the rinsing zone (15), and the method according to the invention thus prevents mixing of different treatment liquids. As a result, an effective treatment of the items of laundry (11), in particular a more effective rinsing thereof, is possible.

  • Publication number: 20030061840
    Abstract: A laundry appliance comprises a drum for receiving articles to be laundered, the drum comprising at least two rotatable drum portions and a drive capable of operating the drum in a plurality of different drum modes. The drum modes include a mode in which the rotatable drum portions are driven so as to cause relative rotation between them. A controller (100) controls the appliance to perform a plurality of different wash programmes, each wash programme having an associated drum mode. Each wash programme comprises a sequence of stages, with a drum mode being associated with each stage. The drum modes can differ in respect of (a) use (or non-use) of relative rotation between the drum portions (b) the ratio of time that the drum portions rotate compared to the time that they are at rest, and (c) the speed at which the drum portions are rotated. The intensity of a wash programme can be varied, inter alia, by varying the length of the wash stage.

  • Patent number: 4951458
    Abstract: A washing machine has a generally cylindrical drum extending along and centered on a horizontal drum axis and a helicoidal auger-like wall centered on an auger axis offset radially from and extending substantially parallel to the drum axis. At least one longitudinally extending rib on an inner surface of the drum is relatively closely spaced to a plane including the drum and auger axes and the rest of the drum inner surface is substantially free of such ribs. This construction allows the machine to operate with substantially higher capacity. During washing oscillation the ribs are lowermost and a much larger load can be accommodated since the drum axis lies between tbe auger axis and the ribs. Normally two such ribs are provided on the drum inner surface closely flanking the plane.
