  • Patent number: 8733135
    Abstract: An inline washing system to be formed from a tunnel-type washing machine (10) which both rinses and removes water from the items of laundry. However, rinsing and simultaneously also water removal can also be performed in the downstream spin-dryer (18) or water-removal press. It has been found that the rinsing performance is better and fresh water can be saved on account of the invention. By virtue of the invention, it is possible to wash relatively small amounts of laundry using a tunnel-type washing machine (10) in an economical manner. The tunnel-type washing machine (10) can be designed to be shorter and also simpler if it is designed without a rinse zone.

Said phases are successive at least once during said washing and/or rinsing processes. In the A phase (intensive wetting), the washing drum accelerates in the first rotational direction (+) up to a rotational speed n1 which is significantly greater than the applicational rotational speed and in the other rotational direction (?) up to a second rotational speed n2 which is significantly less than the applicational speed. In the B phase (high wash mechanics), the washing drum accelerates in both rotational directions up to rotational speeds whereat the individual items of washing are highly spun and are rubbed against each other.

  • Patent number: 7607326
    Abstract: A drum type washing machine including a tub installed in a cabinet is disclosed. The drum type washing machine includes a drum performing washing, a motor rotating the drum, bearing housings having bearings to support a rotation shaft, a suspension connected to the bearing housings and the cabinet to mitigate vibration generated during rotation of the drum, a bracket installed to the bearing housings to form the rear side of the tub, and a gasket installed between the bracket and the tub to seal the tub and to prevent vibration from being transmitted from the bracket to the tub. Volumes of the tub and the drum can be easily increased without increasing the volume of the cabinet. Even when the volume of the washing machine is changed, only one of the tub and the bearing housings, which is not applicable to the drum type washing machine having the changed washing capacity, is selectively replaced. Thus parts can commonly used in various drum type washing machine having different volume.
