- three ribs 49 are provided on the inside of the cylinder jacket 27 are arranged and parallel to the longitudinal central axis 13 continuously over the entire length of the cylinder jacket 27 extend.
- the ribs 49 are on the openings 36 opposite side of the chamber, namely the cylinder jacket 27, arranged.
- the middle of the three ribs 49 is slightly larger than the two outer ribs 49, creating a Vertex 50 of the central rib 49 a greater distance to the cylinder jacket 27 as the apex 50 of the opposite outer smaller ribs 49.
- the blades 39 are completely impermeable to liquids educated. You are so with the partitions 28 and the Cylinder jacket 27 connected, preferably welded, that the Junctions are essentially liquid-tight. At least the partitions 28 of some chambers, especially the Wash chambers 18 are partially liquid-permeable, namely with a perforation 51 from a uniform Provide a grid of through holes.
- the perforation 51 only extends in the exemplary embodiment shown over a lying on one side of the longitudinal central axis 13 Half of the corresponding partition 28 (Fig. 5). It deals this is that half of the partition 28 that the other half of the partition 28 associated opening 36. In the present example there is a central Center region of the cylinder jacket 27 no perforation 51 provided, which has mainly reasons of stability.
- a perforation 51 may also be present in this area. That half of the partition 28, which has an opening 36, and either inlet opening 40 or outlet opening 41, is assigned to the respective opening 36 adjacent edge area is not provided with a perforation 51, so far impermeable to liquids.
- the cylinder jacket 27 of all or certain chambers is also partially with a perforation 52 from a uniform Provide grid of through holes. From the perforation 52 is exempt and is therefore only impermeable to liquids such a part of the relevant cylinder jacket 27, about whose peripheral portion is the inlet opening 40 in the Partition 28 located at the beginning of the respective chamber lies. However, this circumferential area of the cylinder section 30 is also only in the area from the inlet opening 40 to the Cylinder jacket 27 connected lower edge 44 of the blade 39 liquid-impermeable, that is, none. perforation 52 provided. On the other hand, it is from the outlet opening 41 extending to the lower edge 44 of the blade 39 Area of the cylinder jacket 27 designed to be liquid-permeable through the perforation 52.
- FIG. 6 shows various representations a to c Positions of the drum 12 and thus the washing chamber 18 for one so-called pivoting washing movement. From all three representations 6 it can be seen that when washing the Laundry 11 the drum 12 compared to that in FIG. 5th loading and unloading position shown by half a circle (180 °) is rotated so that the inlet opening 40 and the outlet opening 41 in the upper region of the drum 12 in are located substantially above the longitudinal central axis 13. With the perforation 51 provided areas of the partition walls 28 are opposite the inlet opening 40 and the outlet opening 41, are then in the starting position (Fig. 6b) in Area of the lower half of the drum 12, that is, wherever also the laundry 11 and the wash water are located. The Wash water can flow through the perforation 51 in the partition walls 28 flow through the washing chamber 18 and also adjacent chambers, in particular in such a way that the washing water flows in counterflow, thus against the treatment direction 17, the drum 12 flows through.
- the swiveling washing movement starts from the middle position (Fig. 6b) of the washing chamber 18. From this middle position the drum 12 is alternated with the washing chamber 18 over a portion of the circumference in one direction and moves in the other direction, and always only so far that the Inlet opening 40 and the outlet opening 41 in an upper one Area of the drum 12 remain so that during the Washing movement neither through the inlet opening 40 nor through the outlet opening 41 wash water and especially laundry items 11 can get out of the washing chamber 18.
- the washing chamber 18 is turned in any direction rotated about 90 °. Starting from the starting position (Fig. 6b) for example, the drum 12 with the washing chamber 18 rotated clockwise about 90 ° (Fig. 6a) and then turned back 180 ° counterclockwise (Fig.
- the blades 39 in the compartments divide the compartments when it into the lower position shown in Figs. 4 and 5 have driven for loading and unloading.
- the division of the Chambers through the blades 39 is such that neither Laundry 11 still wash water from the entry opening 40 facing concave rear 42 of the blade 39 to that of Exit opening 41 facing convex front 43 of Can get shovel. Because of that on the entrance opening 41 facing concave back 42 of the blade 39 lying area of the cylinder jacket 27 of the chamber, in particular the washing chamber 18, liquid-tight , namely has no perforation 52, wash water can not within a chamber (the wash chamber 18 in FIG. 4) through the annular space 29 between the cylinder jacket 27 and the Flow the outer drum 23 under the blades 39.
- Another special feature of the method according to the invention refers to the fact that the respective relative position (rotary position) the drum 12 is determined. This investigation is preferably carried out without contact, namely continuously.
- a rotary angle encoder measures on the output shaft of the drive motor 26, the speed of the same, thereby drawing conclusions to the proportional rotation of the drum 12 can be derived.
- the measured values obtained in the above manner provide information about the angle of rotation by which the drum 12 has been rotated.
- the speed with which the drum 12 is rotated in particular the angular velocity or peripheral speed can be determined.
- the angular or circumferential speed can also be used Acceleration values of the drum 12 when starting and braking of the drive motor 26 determine.
- the measured values are used to around which the drum 12 when washing the laundry items 11 starting from the middle position (Fig. 6b) in one or other direction is twisted, monitor and to the each to be washed items of laundry 11 to adapt by a corresponding Increase or decrease the swivel angle when Washing the laundry 11.
- the measured values can also be used to: Transfer the drum 12 from the washing positions (Fig. 6a to 6c) in the loading and unloading position (FIG. 5) and to control. This ensures that in the case of Discharge of washing liquid from the washing chamber 18 (middle Chamber of Fig. 4) a drain on the drain box 53 only then is opened when the flow of washing liquid through the drum 12 from itself in the correct position located blades 39 is interrupted.
