Abstract

The method involves at least washing and rinsing items in different chambers (17-19) in a longitudinal sequence in a rotating drum (11). The items are washed in at least some chambers by rotating the drum in one direction and are ejected from the chambers by rotating it in the opposite direction. An Independent claim is also included for an arrangement for wet treatment, especially washing, of wash items.

Description

The invention relates to a method for wet treatment, in particular Washing of laundry according to the generic term of Claim 1. Furthermore, the invention relates to a device for wet treatment, especially washing, of laundry according to the preamble of claim 5 and 10 respectively.

Methods and devices of the type mentioned here concern washing machines for commercial purposes. Such washing machines have a rotating, elongated Drum. The items of laundry are moved lengthways through the Conveyed through and at least washed and rinsed. If necessary, is carried out after the rinsing Equip the laundry items in such a washing machine.

Washing machines are known in which the washing only can be done by an oscillating, alternating drive Drum in opposite directions, the drum only Rotational movements over a small part of their circumference performs. This is necessary in order to promote the To prevent laundry items from the respective chamber of the drum, that in known washing machines by a full circle rotation the drum is brought about. But there are Treatments inside the washing machine are required, the one Require full rotation of the drum. To perform this too can without causing an undesired discharge of the Items of laundry coming from other chambers, the formation of the Drum from several separate, independent drums, whereby an elaborate production of the drum and several drives become necessary.

The invention is based on the object of a device for wet treatment, in particular for washing items of laundry to create, which has a simple structure. As well it is an object of the invention to provide a process for effective wet treatment, especially for the efficient washing of laundry to create that with a simply constructed washing machine is feasible.

A method for solving the problem mentioned at the outset the measures of claim 1. By doing that in at least a chamber of the drum the laundry items by a revolving Rotation of the drum to be washed in one direction while driving the drum in the opposite Direction a discharge of the laundry items from the concerned Chamber takes place, simultaneously on the opposite Side of the chamber new items of laundry are entered into this can, it is also possible, for example, to wash the Laundry items turn the drum around in one direction to let. This allows a different drum in other chambers Treatment, for example post-treatment, of the laundry items take place, the revolving drive of the drum required. So different chambers for different Treatments of the laundry in a common Drum can be accommodated, with all chambers always the perform the same movement.

According to a development of the method, the treatment the items of laundry optionally by a rotating drive Drum in one direction or one (usual) all the time alternating, swiveling rotary movement of the drum over only one Part of their scope. This allows one washing machine operating according to this process is universal deploy.

In terms of method, it is also provided that one rotating drive for washing the laundry, the means when the drum is driven in the washing direction, the laundry to raise in the compartment concerned, what if necessary can be done far that the laundry items from the liquid bath get out to then at least the laundry items to throw back on the bottom of the chamber so that it comes back in immerse the liquid bath. Especially if this Procedure periodically remove the laundry items from the Liquid bath is lifted out and thrown back into it intensive treatment, in particular Laundry, the laundry.

A device for solving the problem mentioned at the beginning has the features of claim 5. So that's the drum by annular partition walls, which are preferably in perpendicular to the longitudinal central axis of the drum Layers are divided into individual chambers. This allows the Drum as such is coherent over the entire length be formed because the partitions separated from each other Chambers for different treatments or successive Form sections of the same treatments. The partitions limit the treatment liquid and the laundry items the respective chamber against such neighboring chambers.

According to a development of the device, the drum formed from itself over the length of the respective chamber extending cylinder jackets and partition walls arranged between them, the partitions the individual drum coats together connect to a one-piece drum. The Partitions therefore have a multiple function. You serve not only to separate the individual chambers, but also for connecting the individual cylinder jackets for continuous one-piece drum.

It is also provided that the partitions are circular form so that they have a central, preferably circular Opening. The fact that each partition on A central, beginning and end of each chamber has an annular opening, through this Items of laundry in the respective chamber, namely one Drum section, enter and through the opening in the subsequent partition is conveyed out of the chamber become. The annular areas surrounding the openings the partition are preferably impermeable to liquids trained, i.e. unperforated. As a result, the partitions serve the treatment liquid in the respective chamber withhold and mix the treatment liquid with those from neighboring chambers to prevent.

According to a development of the invention, the Make partitions larger in diameter than the outer diameter of the cylinder shells forming parts of the drum between two adjacent partitions. In this way stands in the areas of the partitions opposite the outside the drum or the cylinder jacket a circumferential, circular Crossbar in front. This crossbar serves as an outside Sealing the respective chamber from one of the same assigned, preferably stationary outer jacket. The outer jacket has a sliding seal that with the protruding like a ring outside the drum Crossbars correspond. This prevents Liquid that is in the annulus between the drum and the their associated outer jacket of the device does not collect can flow uncontrolled in the longitudinal direction of the drum. In particular can not exchange the fluid on the outer circumference the drum take place between adjacent chambers.

Another device for solving the above Task has the features of claim 10. Therefore the drum has at least one installation that is in such a way the respective chamber is arranged that when turning the Drum the laundry in one direction through the opening in a rear partition can be removed from the chamber and when rotating the drum in an opposite direction Items of laundry remain in the chamber and treated therein, in particular can be washed. The respective installation is in other words, designed only when turning the Drum in one direction laundry items and possibly also Delivers treatment liquid from the respective chamber, but none when turning the drum in the other direction Transfer (and no loading) takes place and takes place of which the laundry items are moved around, namely preferably with at least part of the treatment liquid, being after crossing the top vertex the drum with the laundry items if necessary Treatment fluid are thrown back to the bottom of the Chamber or drum. The laundry and, if applicable, the Treatment liquid are constantly in the respective Chamber raised from installation and thrown back.

The respective installation is in the preferred embodiment the device consists of a curved blade and a Divider. The curved blade extends obliquely to Longitudinal central axis through the chamber, being aligned with the opening the exit side of the chamber closes while it is on the opposite side is above the inlet opening. In this way, the laundry and if necessary, treatment liquid also slide off to Discharge of the laundry and, if necessary, the treatment liquid from the chamber in question, while by the oblique course of the blade on the opposite partition, namely on the entry side, other laundry items and if necessary, treatment liquid in the relevant Chamber can be promoted, simultaneously with the conveyance of the laundry items on the exit side.

Furthermore, one of the opposite is provided The edges of the curved blade at a distance from the outer surface to let the drum end in the area of the respective chamber, thus the items of laundry and when the drum rotates treatment liquid also passed one side of the blade can and therefore not for conveying out of the chamber can get on the shovel. The opposite edge the separator is assigned to the shovel.

The divider consists of a first section of which relevant edge of the blade is guided to the lateral surface and consequently with a corresponding rotation of the drum Items of laundry and possibly also treatment liquid directs the shovel for removal from the chamber in question.

Another part of the divider that faces the convex back the blade extends, is designed in the shape of a circular arc, with a radius of curvature that is half the diameter the central openings at the two bounding the chamber Partitions corresponds. This arched part of the Divider runs parallel to the surface of the drum part of the opening and thus forms one Bag that in the rotation of the drum in one Direction in which, for example, washing takes place Items of laundry and possibly treatment liquid during part of the rotary movement and ensures that the items of laundry are moved up as the drum rotates and only then from the pocket to the bottom of the drum or Chamber can get back if they are next to the entrance opening in the chamber and therefore not the There is a risk that when throwing back on the floor of the Drum the laundry items and, if applicable, those in the Bag of treatment liquid from the inlet opening against the treatment direction of the drum in the previous Chamber of the drum can enter.

According to a preferred embodiment of the device Installation of the drum, both the shovel and that Divider of the same, provided with a closed surface. This makes it possible to also add the treatment liquid corresponding direction of rotation of the drum from the relevant Convey chamber at least partially with the laundry items. On the other hand, with the opposite direction of rotation the drum, i.e. when the laundry is treated, created the opportunity not just laundry items, but also at least part of the treatment liquid from the floor the chamber and then together with the laundry to throw back on the floor of the chamber, causing in particular the washing effect is enhanced and by the mixture the laundry with liquid a better protection of the Items of laundry is achieved if these are not alone, but together with treatment liquid from the divider or from the Bag to be thrown back to the bottom of the chamber.

The device shown here is a Continuous washing machine 10. In the continuous washing machine 10 items of laundry not shown are washed in batches, rinsed and, if necessary, a subsequent aftertreatment, for example, equipment.

The continuous washing machine 10 has an elongated one Drum 11 rotating about a horizontal longitudinal central axis 12 is drivable, specifically in opposite Directions. The drum 11 of the continuous washing machine shown here 10 is divided into different zones, namely one Washing zone 13, a rinsing zone 14 and a finishing zone 15. Die Washing zone 13, rinsing zone 14 and finishing zone 15 are in Treatment direction 16 successively in the drum 11 of the Continuous washing machine 10 arranged. The washing zone 13 and the Rinsing zone 14 are preferably formed from several in the longitudinal direction the drum 11 successive washing chambers 17th and rinse chambers 18, only a few of which are shown in the figures are shown. The number of consecutive wash chambers 17 and rinsing chambers 18 of the washing zone 13 and the rinsing zone 14 can depending on the size and performance of the continuous washing machine 10 vary. In this respect, the invention is not by the embodiment of the continuous washing machine shown here 10 limited. The equipment zone 15 has the Device shown here only through a single equipment chamber 19. If necessary, several successive equipment chambers 19 may be provided at the end of the drum 11. Likewise it is conceivable that there are no equipment chambers 19 at all in the washing zone 14 to follow. It is also possible to use the last one if necessary Use rinsing chamber 18 as finishing chamber 19. Such Pass-through washing machine 10 then does not have its own and equipment chamber 19 used exclusively for equipment.

In front of the drum 11 of the continuous washing machine 10 is an input funnel 20 provided. About the input funnel 20 can Items to be washed in the washing zone 13 of the continuous washing machine 10 are promoted. At the back of the Continuous washing machine 10 is in the embodiment shown an output chute 21 is provided. About this can be done washed and possibly equipped laundry items from the Continuous washing machine 10 are transported out, namely possibly in a subsequent one and not shown Drainage device, for example a drainage press.

In the continuous washing machine 10 shown here, the Drum 11 partially surrounded by a liquid-tight one Outer drum 22. The outer drum 22 serves to receive Treatment liquid, especially water, if necessary Detergent additives are added. The outer drum 22 does not extend over a front and a rear Part of the drum 11. At the front and rear ends of the Pass-through washing machine 10 thereby lies the drum 11 direct drive free. These front and back areas of the Drum 11 each have at least one revolving Race 23, which is supported all around on rotating wheels which are not shown in the figures. Through the said support is the drum 11 about its longitudinal central axis 12 rotatable, which thereby simultaneously the axis of rotation of the drum 11 is. The impeller 24 shown in FIG. 2 is rotating can be driven by a drive motor 25 preferably an electric motor. Others can Motors, for example hydraulic motors, can be used.

The rotatable drum 11 is formed in one piece according to the invention. It has an elongated, cylindrical Shape. The drum 11 is located in the treatment direction 16 the individual chambers in immediate succession, namely washing chambers 17, rinsing chambers 18 and the finishing chamber 19. In the exemplary embodiment shown, all washing chambers 17, Rinsing chambers 18 and the finishing chamber 19 are the same size, in particular of equal length.

Each chamber has a cylinder jacket 26, the one Forms part of the drum 11 and forms in the treatment direction 16 over the entire length or width of the chamber in question extends. Furthermore, the drum 11 has partitions 27, which is perpendicular to the longitudinal central axis 12 of the drum 11 trending levels. Each chamber is limited by two parallel partitions 27, the opposite end faces of the respective cylinder jacket 26 are assigned. Between two successive cylinder jackets 26 different Each chamber has a partition 27. All partitions 27 are preferably of identical design. The partitions 27 are with the end faces of the cylinder jackets assigned to them 26 of the individual chambers connected, preferably hereby welded. In this way, the entire drum 11 is made several in the treatment direction 16 successive Cylinder jackets 26 formed by between adjacent Cylinder jackets 26 arranged partitions 27 with each other are connected. There is a partition 27 between each adjacent cylinder jackets 26 and the front and rear free end face of the cylinder jacket 26 of the first washing chamber 17 and the last chamber, for example the finishing chamber 19, attached.

The cylindrical outer drum 22 has a diameter which is slightly larger than the outside diameter of the drum 11, whereby between the drum 11 and the outer drum 22 a Annulus 28 arises. The outer drum 22 is made of cylinder sections 29 formed. Each of the same sized cylinder sections 29 extends over the area of a chamber, that is, the washing chambers 17 with the exception of the first washing chamber 17, and the rinsing chambers 18. The cylinder sections 29 are on their mutually facing end faces 30 connected together to form a continuous, one-piece outer drum 22. The connection of the individual cylinder sections 29 of the outer drum 22 is done by screwing, facing between each other End faces 30 of two adjacent cylinder sections 29 and the outer end faces 31 of the outer Cylinder sections 29 seals 32 are arranged. Both Seals 32 are all-round rubber seals, which are designed as sliding seals (Fig. 3). The Seals 32 correspond to circumferential crosspieces 33 of the Drum 11. The crossbars 33 are opposite the outer circumference the drum 11 vertically in front. The transverse webs 33 are formed by a corresponding oversize of the partitions 27, whose Outside diameter is larger than the outside diameter of the Drum 11 or the cylinder jacket 26. The cross webs 33 are that is, perpendicular to the longitudinal central axis 12 of the drum 11 running levels of the partition walls 27. The crossbars 33 protrude with outer, free ends in the seal 32, namely protrude into a gap between two adjacent claws 34 Rubber-formed circumferential seal 32 on the inside of the Outer drum 22 (Fig. 3).

Each of the identically designed partitions 27 has one central, circular opening 35. The diameter of the opening 35, whose center is on the longitudinal central axis 12 of the drum 11 is about half the diameter of the drum 11. Preferably, the diameter of the opening 35 is somewhat smaller than the diameter of the drum 11 is namely in Range between 40% and 50% of the diameter of the drum 11. Through the opening 35 in the respective partition 27 is the respective chamber with items of laundry and, if necessary, treatment liquid loadable. Through the opening in the treatment direction 16 subsequent partition 27 can Items of laundry with possibly treatment liquid from the Chamber are promoted.

In particular for conveying out the laundry items if necessary at least part of the treatment liquid from the relevant chamber serves an installation 36 in the respective Chambers. The design and arrangement of the installation 36 in the respective chamber is shown in FIG. 4, which is a section through a washing chamber 17, explained in more detail below:

The washing chamber 17 is delimited by a part of the Drum 11 forming cylinder jacket 26 and opposite End faces 30 assigned to the same, of the same design Partition walls 27. The ones in front in the treatment direction 16 Partition 27 arranged opening 35 serves as an inlet opening 37, while those in the treatment direction 16 rear partition 27 arranged opening 35 as Exit opening 38 is used.

The inside of the chamber, namely the washing chamber 17, arranged installation consists of a partial domed blade 39 and a divider 40. A central one Vertex line 41 of the blade 39, which is shown in FIG Section plane lies obliquely in the treatment direction 16 directed downwards through the washing chamber 17, in such a way that that the apex line 41 with the lowest point of the outlet opening 38 closes and lies above the inlet opening 37. As a result, the funnel-like curved blade 39 runs approximately across the wash chamber 17. With across the longitudinal central axis 12 running edges is the blade 39 on the inside of the attached to each partition 27, for example by Welding. The edge of the outlet opening 38 Bucket 39 is curved so that it matches the edge of the Exit opening 38 closes, so that the blade 39 surrounds a portion of the outlet opening 38 that is somewhat is greater than half the circumference of the outlet opening 38 next to (in FIG. 4 above) the inlet opening 37 The edge of the blade 39 is essentially straight.

Opposite, running across the washing chamber 17 The edges 42 of the blade 39 run in the treatment direction 16 inclined slightly downwards from the top of the inlet opening 37 to the outlet opening 38. One of the edges 42 of the blade 39 ends as a free edge in the washing chamber 17, with Distance from the cylinder jacket 26 of the washing chamber 17. On this Way between this free edge 42 of the blade 39 and the cylinder jacket 26 items of laundry and also treatment liquid move freely along the free edge 42 or flow past.

The opposite edge 42 of the blade 39 is with the Divider 40 connected. This extends from the edge 42 Partition plate 40 with a flat surface section 43 radially from the concave side of the blade 19 facing away to the outside to the inside of the cylinder jacket 26. This allows between this edge 42 of the blade 39 and the cylinder jacket 26 neither Items of laundry still have treatment liquid between the shovel 39 and pass through the cylinder jacket 36. Towards the convex rear side 44 of the blade 39 an arcuate region 45 of the partition plate 40 extends with a parallel distance to the cylinder jacket 26 in a partial area along the inlet opening 27. This will make the Back 44 of the bucket 39 a pocket 46 between the Partition plate 40 and the cylinder jacket 26 of the washing chamber 17th formed (Fig. 5 to 7). A free transverse edge 47 that is parallel runs to the cylinder jacket 26, ends at a slight distance in front of the vertical section plane of Fig. 4, in which the oblique Vertex line 41 of the curved blade 39 on a the longitudinal central axis 12 intersecting vertical wash basin center plane 17 lies (Fig. 4 and Fig. 7d).

The partitions 27 are except for the central openings 35 closed, in particular completely liquid-tight. The blade 39 and the divider 40 in the respective chamber have closed areas, so are liquid-tight. In contrast, the cylinder jacket 26 is partial liquid-permeable, namely with a uniform Perforation from a regular grid of thin holes (partially shown in Fig. 4). This partially Perforation of the cylinder jacket 26 is such that in the area the pocket 46, preferably in a portion of the same Partition 27 has no perforation. It is about here around that area of the cylinder jacket 26 which corresponds to the arcuate portion 45 of the divider 40 on the convex Back 44 of the blade 39 is opposite. Preferably that opposite the arcuate portion 45 of the divider 40 Area of the cylinder jacket 26 only partially perforated by starting from the free transverse edge 47 of the arcuate portion 45 of the divider 40 the perforated The area of the cylinder jacket 26 decreases continuously until End of the pocket 46 where the cylinder jacket 46 completely is designed to be liquid-tight, that is to say over its entire length Width has no perforation. If necessary, however the entire cylinder jacket 26 may also be perforated.

The continuous washing machine 10 described above works according to a method which is described with reference to FIGS. 5 to 7 is explained in more detail below:

Via the central inlet opening 37 in the direction of treatment 16 seen front partition 27 of the respective chamber the laundry and possibly also treatment liquid namely wash water, in the wash chamber in question 17. This type of centric delivery of at least Items of clothing in the wash chamber 17 is known in technical jargon Center transfer designated.

5 shows different representations a, b and c Positions of the drum 11 and thus the washing chamber 17 for one so-called pivoting washing movement. Starting from a middle position (Fig. 5b) of the washing chamber 17, the 4 corresponds to the position of the wash chamber 17 in the central section, the drum 11 with the washing chamber 17 alternately over a portion of their circumference in one direction and in the other direction moves. In the embodiment shown the washing chamber 17 is rotated by approximately 90 ° in each direction. Starting from the starting position (FIG. 5b), for example first the drum 11 with the washing chamber 17 by about Turned 90 ° clockwise (Fig. 5a) and then 180 ° turned back (Fig. 5c). This is followed by another one Backward movement of the washing chamber 17 clockwise by 180 °. The items of laundry are thereby constantly in the washing drum 17 swinging back and forth together with the washing liquid. Opposite the inner wall of the cylinder jacket 26 the washing chamber 17 projecting ribs 49 support the Washing process by making a movement of the laundry items in 5 to 7 are symbolically represented by squares, in

Bring wash water. In addition, the wash water partially carried in the direction of rotation by the ribs 49 (Figures 5a and 5c). In the embodiment shown, the Inside the cylinder jacket 26 three ribs 49 with a uniform Distance of about 50 ° based on the inner circumference of the Cylinder jacket 26 arranged. The central rib 49 lies here in the neutral position of the washing chamber 17 under the longitudinal central axis 12 (Fig. 5b). The number and training of Ribs 49 can have three from the embodiment shown here Ribs 49, which have an acute-angled cross section, differ.

The continuous washing machine 10 according to the invention enables alternatively washing the items of laundry in the washing chamber 17 with rotating drum 11, which during the washing process performs several full circle rotations (Fig. 6a to 6d). Starting from a neutral position in which the washing chamber 17th with items of laundry and, if necessary, washing water from the previous one Wash chamber 17 or the feed hopper 20 is loaded is (Fig. 6a), the drum 11 is rotating against the Driven clockwise. The laundry items arrive with the washing water in the pocket 46, that is, the annular space between the cylinder jacket 26 and the partition 40 of the Installation 36 (Fig. 6b). When the drum 11 is turned further the laundry items with at least part of the washing liquid due to the liquid-tight partition plate 40 and partially liquid-tight in this area Cylinder jacket 26 in the area of the pocket 46 from the partition plate 40 raised, up to about the longitudinal central axis 12 of the Wash chamber 17 (Fig. 6c). If the Drum 11 with the washing chamber 17 over a horizontal Position of the flat surface section 43 of the partition plate 40 In addition, the laundry items with the in the pocket 46th conveyed wash water out of the pocket 46 beyond the free transverse edge 47 of the partition plate 40, whereby the laundry and the washing liquid in free fall fall back into the lower area of the washing chamber 17 (FIG. 6d). The items of laundry and the washing water carried along arrive thereby again in the bottom region of the cylinder jacket 26

Wash chamber 17 are thus again in the starting position (Fig. 6a). By rotating the drum 11 several times the washing chamber 17 is the movement described Items of laundry repeated with the wash water, causing it to an intimate relative movement between the laundry and the washing water with an effective washing of the laundry items is coming.

After completion of the laundry in the washing chamber 17, the Laundry items with at least part of the wash water from the Blade 39 through the central outlet opening 38 in the in Treatment direction 16 rear partition 27 from the Wash chamber 17 in turn by a so-called top transfer promoted, in the next chamber, where it is a further washing chamber 17 or a first rinsing chamber 18 can act.

For conveying out the laundry and the washing liquid the washing chamber 17, the drum 11 is in the opposite Direction as rotating for washing, namely in Embodiment shown clockwise (Fig. 7a to 7d). Here, the laundry items get the washing liquid not in the pocket 46 on the back 44 of the bucket 39, but at a distance from the inside of the cylinder jacket 26 ending free edge 42 of the blade 39 over on the concave inside of the scoop 39 where the laundry items and the washing liquid is not yet in the dispensing position located bucket 39 first on the flat surface section Support 43 of the divider 40, on the side facing the concave inside of the blade 39 points, that is directed away from the pocket 46 (Fig. 7b). At the The flat surface section passes the drum 11 further 43 of the partition plate 40 over a horizontal position in a executed slightly towards the concave side of the blade 39, oblique position, with the flat surface section 43 Items of laundry with the washing water on the curved scoop 39 arrive (Fig. 7c). Upon further rotation of the drum 11 with the Wash chamber 17 reaches the flat surface section clockwise 43 of the divider 40 finally into a vertical Position in which the laundry and the washing liquid carried completely over the curved, inclined blade 39 through the outlet opening 38 from the washing chamber 17 into the next chamber to be promoted (Fig. 7d).

According to the operation of the continuous washing machine described above 10 can wash in the washing chamber 17 Items of laundry optionally by a swiveling back and forth Movement of the drum 11 with the washing chamber 17 (Fig. 5a to 5c) or a continuous rotary movement of the drum 11 several complete turns of the same (Fig. 6a to 6d). Through the corresponding installation according to the invention 36 in the washing chamber 17 ensures that even at complete rotation of the drum 11 with the washing chamber 17th in one direction, namely in the embodiment shown counterclockwise (Fig. 6a to 6d), neither the laundry still washing liquid conveyed out of the washing chamber 17 become. If, however, there is a rotating drive Drum 11 with the washing chamber 17 in the opposite direction, that is, clockwise in the exemplary embodiment shown (Fig. 7a to 7d) enables the designed according to the invention Installation 36 in the wash chamber 17 a conveying out washed laundry items with at least part of the washing liquid from the washing chamber 17 through the outlet opening 38 into the next chamber.

In the manner described above, all washing chambers 17, Flushing chambers 18 and the finishing chamber 19 may be formed and operated. But it is also conceivable, only one or form and close a plurality of washing chambers 17 as described operate and one or all rinsing chambers 18 and / or the equipment chamber 19 to train or operate differently. This can in particular by a modified installation 36 in the respective Chamber happen.

By washing the laundry in the washing chamber 17 with the installation described 36, it is possible to drum 11 Washing either spinning in alternating directions, and only over part of the circumference of the drum 11 or continuously in one direction, the drum 11 makes several complete rotations during the washing process. By the choice of the drive of the drum 11th for washing the items of laundry that are in during the washing process the same wash chamber 17 can change by putting the laundry in this washing chamber 17 partly by oscillating, back and forth Herewith rotary movement of the drum 11 and partially by a complete drum rotation at least once, it is possible to process the laundry items in to influence subsequent chambers. Such influencing can be done, for example, such that a Full rotation of the drum 11 counterclockwise embodiment shown the laundry and the Wash liquid remain in the relevant wash chamber 17 and further washed in a subsequent chamber but a transfer of the laundry items from one chamber to another or an issue of the laundry items from the following Chamber is done. The invention also contributes to this Training of the drum 11, which from coherent interconnected chambers, in particular washing chambers 17, Rinsing chambers 18 and finishing chamber 19 is formed.
