Definitions

  • a continuous washing machine comprises a drum dI- y 3 vided axially into a plurality of washing chambers.
  • a helical feed passage is arranged on one side of the 68/145 83623 283 chambers and is arranged to feed batches of washing 58] 142 146 from one chamber to an adjacent chamber during ro- N 7 3? 1 6 3 4 tation of the drum in one direction. Rotation of the drum in the reverse direction causes the batches to re- 1 References Cited main in the respective chambers.
  • German Offenlegungsschrift No. 1.949.045 it has been proposed to arrange in a helical inclined planes on the inner surface of the washing drum of a continuous washing machine.
  • the inclined planes connect adjacent partitions which are provided with openings extending to the inner surface of the drum.
  • This washing machine has the disadvantage that some items of the wash can pass from one washing chamber into another washing chamber during a washing operation. Effective separation of the batches of washing is not ensured because items of the wash fall through the openings in the partitions during the washing operation.
  • a continuous washing machine having a washing drum including a helical transport passage with washing chambers arranged on one side.
  • the transport passage comprising a conveyor worm partially surrounded by a jacket, or helical inclined transport surfaces which are partially surrounded by jacket surfaces.

  • FIG. I8 is a fragmentary perspective view of the washing machine of FIG. 16 viewed from the other side thereof during the washing operation after the washing has been taken up by a lifting surface;
  • FIGS. 19 to 21 are fragmentary perspective views of the washing machine during different stages of a feeding operation.
  • the washing machine comprises a conveyor worm having a helical thread form 2 with outer edges 2a (FIGS. 1 and 2).
  • the worm l is surrounded by a semi-cylindrical jacket 3 which closely fits on the outer edges 2a of the helical thread form 2 and has a through opening 4 extending in longitudinal direction of the jacket (FIGS. 3 and 4).
  • the jacket 3 is firmly connected to the worm l.
  • a washing drum 5 (FIGS. 5 to 7) is subdivided into individual chambers or treatment zones 17 by partitions 6.
  • the partitions 6 are sickle-shaped to accommodate the worm l and the semi-cylindrical jacket 3 surrounding the latter.
  • the longitudinal axis 7 of the worm I is eccentrically mounted in relation to the longitudinal axis 8 of the drum 5.
  • the jacket 3 is also rigidly connected to the partitions 6 and hence is rigid with the drum 5.
  • the pitch 5 of the worm thread form approximately corresponds to the width b of the individual treatment zones have different widths.
  • the pitch s of the worm varies correspondingly from one treatment zone to the next.
  • a lifting surface 9 which is bounded on one side by the cylindrical jacket 3 and on the other side by the drum 5.
  • a helical feed passage 10 is formed which is partially defined by the helical thread form 2 of the worm l and the semi-cylindrical jacket 3.
  • the feed passage 10 extends through the partitions 6 and interconnects the individual treatment zones 17.
  • the washing machine described above operates as follows;
  • FIGS. 8 to 11 show the washing machine during a washing operation. As can be seen from FIG. 8, the
  • the lifting surface 9 engages the washing lying at the bottom of the washing drum 5 and lifts it in the direction of the arrow into the position shown in FIG. 11.
  • the washing is caused to leave the feed passage and is discharged via the opening 4 into the next treatment zone of the washing drum 5.
  • the washing drum is then in the position shown in FIG. 12. Feeding of the washing from one treatment zone to the next is therefore carried out by approximately one revolution of the washing drum 5.
  • the water flow within the washing drum can be so regulated that during washing and feeding, the water flows back into the treatment zone or flows on into the next treatment zone according to the position of the perforations. In this way it is possible to control the flow of water through the washing drum whereby the water flows through the drum in a direction opposite to the direction of movement of the washing through the drum.
  • washing chambers are connected to a helical feed passage 10.
  • the washing drum 5 is divided by partitions 6 into individual treatment zones.
  • the partitions 6 differ from those of the previous embodiment in respect of their inner outline.
  • the helical feed passage 10 is partially formed by bending a portion of the partitions 6 over about half the width b of a treatment zone 17 at an obtuse angle a. about half the pitch 5' of the helical passage being obtained in this way.
  • the surface of the partition 6 which is inclined by the bending constitutes a feed surface 11, the remaining part 12 of the bent portion extends parallel to the unbent portion of the partition.
  • lifting surfaces 14 and sliding surfaces 15 which extend in the longitudinal direction of the washing drum 5.
  • the lifting surface 14 is connected at a longitudinal edge 14a to the inner surface of the washing drum, its other longitudinal edge 14b being followed by a sliding surface 15 inclined thereto at an obtuse angle [3 (FIGS. 17 and 18).
  • the feed passage 10 is surrounded within the washing drum by the lifting surfaces 14 and the sliding surfaces 15 and externally by part of the drum 5.
  • the lifting surfaces 14 and the sliding surfaces 15 can be perforated.
  • Guide faces 16 extending parallel to the longitudinal axis 8 of the washing drum 5 connect the partitions 6 and constitute the central axis of the feed passage 10; the faces 16 serve to prevent the washing from sliding back along the feeding surfaces 13 into the original treatment zone, during a feeding operation.
  • the washing drum 5 and hence also the parts which are directly or indirectly connected thereto is rotated in the direction indicated in FIG. 18.
  • the washing in the lower part of the washing drum 5 is lifted by the lifting surface 14 and during continuing rotation the sliding surface 15 moves beyond its horizontal position into an inclined position so that the part of the washing lying on this sliding surface 15 begins to slide downwards and falls into the lower part of the washing drum 5.
  • the lifting faces 14 and the sliding faces 15 can be perforated.
  • the washing machine particularly described provides an optimum, but gentle. washing action and is relatively inexpensive to produce.
  • said feed means comprising means defining a separate helical feed passage for each of the plurality of separate chambers arranged on one side of each chamber.
  • said passage-defining means comprising means defining helically inclined feed surfaces. and means defining surfaces partially surrounding the helical surface-defining means.
  • said dividing means being in the form of partitions. and the helical surface-defining means comprising portions of the said partitions, said portions being bent to extend across about half of the width of each chamber.
  • a washing machine according to claim 1 wherein the said surfaces partially surrounding the helical feed surface are formed by the inner surface of the drum which surface externally surrounds the helical feed surface. a lifting surface. and a sliding surface. said lifting surface forming said moving means.
  • passage-defining means further comprise guide surface means extending parallel to the axis of the washing drum. said guide surface means connecting adjacent said partitions.
  • each said lifting surface is inclined at an obtuse angle to a following said sliding surface.
  • a washing drum having a surface and a longitudinal axis. said drum being rotatable about said longitudinal axis.
  • partition means dividing the interior of the drum into a plurality of separate chambers.
  • said feed means comprising means defining a helical feed passage for each of the plurality of separate chambers. the passages being located in the drum eccentrically with respect to the longitudinal axis of the drum.
  • each of said apertures having edges transverse to the longitudinal axis of the drum. and first and second opposed edges extending longitudinally of the drum. said first edge lying adjacent the surface of the drum, and said second edge being spaced from the surface of the drum.
