For washing the screw is oscillated back and forth about the axis through substantially more than 360.degree. to agitate the articles in the liquid. Periodically the screw is rotated about the axis through substantially more than 720.degree. in a rotation direction to advance the batches axially opposite the direction of liquid flow.

  • Patent number: 4467535
    Abstract: This invention relates to a foldable, removable drier divider assembly with removable suction cup pieces that can be easily inserted into a household drier and quickly secured in its operating unfolded position to act as a drier drum divider for separating materials or objects during the drying process in order to dry several non-mixable materials or objects in one operation that otherwise would take several drying operations. The drier assembly consists essentially of a rotatable core unit with a plurality of divider fins extending from it whose outer periphery in their open operating position substantially fit and rotate with the interior of the rotating drier drum without rubbing against the stationary portions of the drier interior.

  • Patent number: 4422309
    Abstract: A tunnel-type batch washing machine has an outer tunnel-forming housing tube centered on a horizontal axis and provided internally with a helical wash screw rotatable in the tube about the axis and having a plurality of flights defining axially spaced compartments. A generally cylindrical sleeve is fixed to this screw and is coaxially received within the tube between the screw and the tube. A treatment liquid is flowed axially in one direction through the housing and respective batches of articles to be washed are held in the compartments between the flights. For washing the screw is oscillated back and forth about the axis through substantially more than 360.degree. to agitate the articles in the liquid. Periodically the screw is rotated about the axis through substantially more than 720.degree. in a rotation direction to advance the batches axially opposite the direction of liquid flow.

  • Patent number: 4391108
    Abstract: A drum for a continuously operating laundry processing machine is constructed from a number of individual elements. Each element consists of an upper and a lower portion having a surface of helical shape which defines part of the drum shell, and a surface of right helicoidal shape which defines part of a right helicoidal conveying screw which divides the drum into individual chambers. The parts forming the drum are connected by externally welded seams.

  • Patent number: 4210004
    Abstract: A batch washing machine comprises an imperforate drum open at both ends and mounted for rotation about a substantially horizontal axis. A conveyor worm having an imperforate helical surface is rigidly mounted in the interior of the drum to divide same into a plurality of individual chambers. Washing media is fed to the chambers by means of a pipe disposed on a central axis of the drum, the pipe being sub-divided into individual pipe portions by the helical surface of the conveyor worm, with each pipe portion including at least one outlet aperture communicating with a respective one of the chambers. At least one emptying aperture is provided in the drum for each chamber and through which washing media can be discharged from the chamber. During washing, each chamber is separated from the other chambers, so that the machine can wash different types of washing at the same time.

  • Patent number: 4034583
    Abstract: A washing machine comprises a rotatable washing drum divided by an internal screw conveyor into a number of separate washing and rinsing zones. A chamber mounted on the external surface of the drum in the area of the principal washing zone communicates with the principal washing zone and contains a partition which defines a liquid-containing pocket. This pocket is at least partially filled with liquid throughout rotation of the drum and contains a heating device which acts to heat the liquid.

  • Patent number: 3995458
    Abstract: The invention relates to a laundry machine comprising a washing drum which is rotatable about its longitudinal axis; the generated surface of the drum being formed with apertures through which washing liquid can flow. The drum is supported, preferably by an endless retaining element, such that an outer surface of the drum is spaced apart from an inner surface portion of a casing. At least one partition extends substantially radially inside the drum thereby dividing the drum into discrete segments. The partition has an aperture and conveyor means are disposed inside the drum for conveying laundry from one segment of the drum to an adjacent segment thereof via the aperture. A flange extends substantially radially outwardly from the drum, and from between each pair of adjacent segments thereof, thereby dividing the gap between the drum and the casing into pockets or chambers, means being provided for obtaining a fluid-tight seal between each flange and the casing.
