    The invention relates to a washing device which has a washing chamber with at least one washing nozzle arranged therein and a carousel arranged therein, wherein the carousel receives the laundry and is mounted rotatably about an axis and the washing device is tiltably mounted to the horizontal. The invention further relates to a system comprising a washing device and a plurality of washing cars, which are interchangeable and a system of washing device and laundry, in the game between the laundry and a Waschgutaufnahme the washing device consists. The invention further relates to a method for washing laundry, is introduced and washed in the laundry in Waschgutaufnahmen, wherein the Waschgutaufnahmen are dimensioned larger than the laundry.
    In many industries come during transport and internal logistics of parts so-called small load carrier (KLT) are used. These small load carriers serve as a receptacle and packaging for the parts and should protect them from damage during transport. In order to be able to fulfill these tasks, the small load carriers are usually adapted to the shape of the parts they are to receive. By this positive connection, the parts in the small load carrier can hardly move and are thus safely packed. The more complex the shape of the male parts, the more complex the shape of the small load carriers, if a secure recording of the parts is to be ensured. In ABS control units, for example, solenoid coils are needed to control the hydraulic circuits. When assembling the ABS control units, these magnetic coils, which have filigree connection legs for connection to a printed circuit board, are delivered in small load carriers which have receptacles which correspond exactly to the magnetic coil with the attached connection legs. This ensures that the magnetic coils are safely picked up during transport and not damaged. The small load carriers used are often constructed in several parts. To pick up on the example of the solenoid coils for ABS control units, these small load carriers, for example, blisters, which receive the magnetic coils directly. These blisters are then packed in customized boxes and closed with custom lids. Such a small load carrier or such a system of small load carriers is often used in the reusable method. This means that initially a batch of parts is transported with the small load carrier. After removing the parts, the small load carriers are then returned to the manufacturer and used for further transport. This makes sense especially when complex small load carriers are expensive to produce. As part of this reusable method, small load carriers have to be cleaned cyclically. Due to the described complexity of the shape of the small load carriers cleaning liquid from the small load carriers can often be removed only insufficiently when cleaning. Washing machines for cleaning small load carriers are known. In these washing machines, the small load carriers are first washed with liquid and dried in a subsequent spin cycle. Especially in undercuts the small load carrier often remains cleaning liquid after completion of the cleaning process, since this cleaning liquid can not be removed during the spinning process. Since remaining cleaning liquid is unacceptable in the transport of sensitive parts, such as in the previously described magnetic coils, great effort is spent on the drying of such small load carrier. Nonetheless, if cleaning liquid remains in the small load carriers, mass production of complex products, in which the remaining cleaning liquid is not immediately noticeable, can quickly lead to great damage and possibly even high claims for damages for the supplier.
    It is therefore an object of the invention to propose a way as small load carriers can be safely and economically washed and dried.
    This object is achieved by a washing device which has a washing chamber with at least one washing nozzle arranged therein and a carousel arranged therein, wherein the carousel receives the laundry and is rotatably mounted about an axis, the washing device is tiltably mounted to the horizontal and a tilting device is provided, which tilt the washing device by an angle relative to the horizontal to produce a drain state of the washing device. A washing device or washing machine according to the invention has a washing chamber in which the actual washing process takes place. At least one washing nozzle is arranged in this washing chamber. Conveniently, however, several washing nozzles are provided, which spray cleaning liquid from different directions on the laundry in the wash chamber. Washing nozzles which release the cleaning liquid under high pressure are particularly suitable. Optimum cleaning results can be achieved with rotating washing nozzles, which rotate around a fixed pivot point and spray cleaning fluid in a circular manner. An inventive washing device further comprises a rotatable carousel, which is arranged in the interior of the washing chamber. This carousel is rotatably arranged about an axis which extends vertically in the resting state of the washing device. Carousel according to the invention are to be understood as meaning various constructions which are suitable for receiving laundry and being driven in rotation by a drive device. A carousel may for example consist of a round bottom plate, on the edge of the bottom plate several struts are mounted, which extend vertically upwards. These struts form a kind of cage within which laundry can be introduced. A carousel constructed in this way can then be driven in rotation, for example, by a drive motor mounted on the upper edge of the washing chamber. Of course, the invention is not limited to this embodiment of a carousel. The rotability of the carousel is used to carry out a spin process after washing with the cleaning liquid, which removes remaining cleaning liquid from the laundry with the help of centrifugal force. According to the invention, it is further provided that at least part of the washing device, namely the washing chamber with the rotating carousel mounted therein, is designed to be tiltable relative to the horizontal. In order to actually tilt the washing device according to the invention a tilting device is provided. If necessary, this tilting device moves the washing device from the basic position into a drainage state. In the basic position, in which the loading of the washing device with laundry takes place, the axis of rotation of the carousel is oriented vertically. To assume the drainage state, the tilting device tilts the washing device by an angle relative to the vertical basic position of the axis of rotation. By tilting of course also changes the angle of the washing device or the axis of rotation of the carousel to the horizontal. In the basic position, this angle is equal to the horizontal 90 °. If the washing device is transferred by the tilting device into the drainage state, this angle of the washing device or the axis of rotation of the carousel is reduced to the horizontal and then, for example, is only 70 °. According to the invention, all angles between 90 and 0 ° of the axis of rotation of the carousel to the horizontal can be provided. It is also associated with the invention to use drain states with different or varying tilt angles to the horizontal. The inventive, tilted run state of the washing device has significant advantages over the prior art with respect to the removal of residual cleaning liquid from the laundry. Without this tilted drainage state, cleaning liquid remaining after washing can only be thrown off about the vertical axis of rotation by a rotation of the carousel. If the laundry has undercuts in its geometry, it is possible for cleaning fluid to remain in these undercuts despite the spinning process. This remaining cleaning liquid can be removed manually, but this causes high labor costs. Furthermore, it is possible to dry this remaining cleaning fluid by high ambient temperatures. However, this results in high energy costs and it takes a lot of time. With a washing device according to the invention, gravity is advantageously used to remove remaining cleaning liquid. The tilting device initially places the washing device in a drainage state in which the rotational axis of the carousel is no longer vertical but in a position between vertical and horizontal orientation. In this process state, the carousel is then rotated at a slow speed. Due to the tilted position of the laundry, remaining cleaning liquid can now run down in undercuts or similar complex geometries caused by gravity. By tilting such a drainage is also possible from areas that were closed in the vertical position by hindering geometric elements. The rotation about the tilted axis allows gravity to be applied in different directions with respect to the laundry. If there is an undercut in one direction, which prevents the drainage of cleaning liquid, then in another direction, in which the gravitational force engages at another time due to the rotation of the carousel, this undercut no longer exists and the cleaning liquid then runs off in that direction. By repeated rotation of the laundry around an axis tilted to the vertical or horizontal axis according to the invention remaining cleaning liquid is completely removed from the laundry. If residual moisture still remains on the laundry, it can be completely removed by conventional centrifuging or a short drying at higher temperatures, if necessary.
    In a preferred embodiment it is provided that the drain state is provided as part of a washing process of the washing device. In this embodiment, the drain state is just one of several parts or process steps of a wash. Conveniently, the drain state after cleaning the laundry is taken with a cleaning liquid to remove the cleaning liquid from the laundry. However, it is also possible to perform several wash cycles, so that the state of drain is taken several times in a washing process. Thus, it may be provided, for example, first to carry out a rough cleaning of the laundry, then to remove the cleaning liquid used for this purpose in a run-off state, and then to carry out a final rinsing process with different cleaning liquid for final cleaning. Also, this cleaning liquid of the final cleaning process can then be removed yet another state of drainage completely from the laundry.
    Skillful way is provided that a tilting axis is provided, which extends at the bottom of the washing chamber in the horizontal direction and the tilting device tilts the washing chamber in the transition state in the state of drain about the tilting axis. In this embodiment, the washing device or the washing chamber is tilted about a horizontally extending tilting axis. It has been found to be convenient to arrange this tilting axis at the lower end of the wash chamber. Such an arrangement of the tilting axis allows a simple construction of the washing device, since the tilting axis is arranged in the vicinity of the substrate below the washing device. Such an arrangement is also advantageous in the retrofitting of existing washing devices with the function of tiltability. The tilting axis is also very easy to install in this case between the substrate and wash chamber. Of course, it is also possible to arrange the tilting axis higher in the vertical direction on the washing device, for example in the middle region or in the upper region of the washing chamber.
    In an advantageous embodiment it is provided that the tilting axis and the tilting device, viewed in the horizontal direction, are arranged opposite sides of the washing device. In this embodiment, the tilting device is arranged on the opposite side of the tilting axis on the washing device. This arrangement is particularly favorable when the tilting device is designed as a linear drive, for example as a hydraulic cylinder. The linear movement of the tilting device is translated about the tilting axis into a rotation about this tilting axis.
    This opposite arrangement of tilting and tilting axis in turn also has advantages when retrofitting existing washing devices with a tilt function, since the additional required elements tilting axis and tilting device can each be easily mounted laterally on the washing device.
    In a further preferred embodiment it is provided that the tilting device is designed as a linear drive, one end of which is connected to the substrate of the washing chamber and the opposite end to the washing chamber. In this embodiment, the tilting device is designed as a linear drive, for example as a hydraulic cylinder. One end of this linear drive is rotatably connected to the substrate of the washing chamber or washing device. The opposite end of such a tilting device is connected to the washing chamber, and this connection is made rotatable. When the washing device tilts, the tilting device changes its length. Thereby, the washing device is moved about the tilting axis in a rotation. In this case, the angle of the tilting device to the ground and the angle of the tilting device to the washing chamber or washing device changed.
    Furthermore, it is provided in a favorable manner that the tilting device is designed as a push chain drive, wherein the push chain drive is fixed to the substrate of the wash chamber and the end of the push chain of the push chain drive is connected to the wash chamber. In this embodiment, a push chain drive is used as a tilting device. Under push chain is to understand a back-stiff chain, which is in a direction like a normal chain can be rolled, but in the other direction forms a stiff back and thus can transmit shear forces. The push chain drive is conveniently fixed to the substrate of the wash chamber and has a rolled-up push chain in the basic position, the end of which is rotatably connected to the wash chamber. When transitioning to the flow state, i. when tilting the washing device, then the push chain drive is actuated, whereby the push chain is rolled out. Due to the back-rigid design of the push chain this pushes the washing device without further guide elements in a rotational movement about the tilt axis. Such a push chain drive has the advantage that it is particularly easy to install and space-saving.
    In a further preferred embodiment it is provided that the tilting device is designed as a hydraulic cylinder, as a combination of rack and rotating pinion, as a combination of spindle and rotating spindle nut, as an electric linear drive or as a combination of rope and winch. In this embodiment, various other possibilities for forming a tilting device are alternatively mentioned. This list is not exhaustive, i. There are also other concepts for the realization of the inventive washing device into consideration. In general, all concepts are suitable which allow stable tilting of the entire washing device or at least the washing chamber relative to the horizontal.
    Advantageously, it is provided that the carousel has at least one Waschgutaufnähme, in which the laundry is introduced during the washing process, wherein the inner dimensions of the Waschgutaufnahme are greater than the outer dimensions of the laundry and the laundry is thereby arranged movably within the Waschgutaufnahme during the washing process , In this embodiment, it is provided that the laundry is introduced into at least one Waschgutaufnahme during the washing process. Depending on the size of the laundry can also be provided several Waschgutaufnahmen. In general, so many Waschgutaufnahmen are provided that the available space in the wash chamber is made the best possible use. The Waschgutaufnahme is attached directly to the carousel in this embodiment. It is of course possible to carry out various types of Waschgutaufnahmen on the carousel and replace them as needed. The inner dimensions of the Waschgutaufnahme are executed in this embodiment larger than the outer dimensions of the laundry. This creates a distance or clearance between the laundry and the Waschgutaufnähme receiving this laundry. The laundry is thus movable during the washing process for Waschgutaufnahme. However, this flexibility is limited to the game between the two elements. This means that the laundry does not move freely like a cleaning drum and can fall apart, but that it has only a relatively small movement space within its Waschgutaufnahme. This small space for movement is therefore chosen to protect the laundry from damage by other laundry. Especially in the field of small load carriers, the laundry is often filigree and prone to damage. The inventive Waschgutaufnahmen are conveniently adapted to the shape of the respective laundry and allow movement of the laundry within the Waschgutaufnahme that can take the laundry without being damaged. A certain mobility of the laundry in the Waschgutaufnahme is in the removal of remaining cleaning fluid of great importance. The play between the laundry and the laundry may cause the laundry to move in the drain position when the carousel is rotated about a tilted axis due to gravity. The laundry falls in this oblique rotation so to speak within the Waschgutaufnahme back and forth. As a result, gravity attacks in still more different directions of remaining cleaning liquid, as would be the case with a firm leadership of the laundry in the Waschgutaufnahme. In addition, during the back and forth falling of the laundry small mechanical impulses occur upon impact of the laundry on the Waschgutaufnahme, whereby remaining cleaning liquid is additionally shaken off by this mechanical impulse.
    In a preferred embodiment it is provided that the washing device comprises at least one washing carriage, which can be introduced into the carousel and removed therefrom and which is rotatable about the axis with the carousel and the washing carriage has at least one Waschgutaufnahme in which the laundry is introduced during the washing process, wherein the inner dimensions of the Waschgutaufnahme are greater than the outer dimensions of the laundry and the laundry is thereby arranged movably within the Waschgutaufnahme during the washing process. In this embodiment, a washing carriage is provided, which receives the laundry and which is then loaded with the laundry for the washing process in the carousel is introduced. The provision of such a washing carriage has the advantage that it can be conveniently loaded and unloaded outside the washing device with laundry. The washing car is fixed after insertion into the carousel at this, for which various fixation elements can be provided. During a rotation of the carousel, the washing car then rotates together with the carousel. A movement of the car in the carousel is not provided in this embodiment. In contrast to the embodiment described above, the at least one Waschgutaufnahme is now not arranged directly on the carousel but on the washing car. Also in this embodiment, the inner dimension of the Waschgutaufnahme is designed to be greater than the outer dimension of the laundry in order to achieve a mobility of the laundry in the Waschgutaufnahme. For this mobility, the description of the previous embodiment applies.
    Skillful way it is provided that the washing device comprises at least one washing car, which can be introduced into the carousel and removed therefrom and which is rotatable with the carousel about the axis, wherein the washing carriage is designed to be movable within the carousel and on the washing car at least one Waschgutaufnahme is provided, in which the laundry is introduced during the washing process, wherein the inner dimensions of the Waschgutaufnahme correspond to the outer dimensions of the laundry, so that there is a positive fit between laundry and Waschgutaufnahme. In this embodiment, a washing carriage is provided, which is designed to be movable within the carousel of the washing device. This washing car is not fixed in the carousel during operation of the washing device. Typically, the washing car at its lower end on rollers, where it rolls on the ground during transport. These rollers also allow movement of the wash cart within the carousel. For this purpose, the washing car is designed to be smaller than the carousel. When the carousel is rotated about a tilted axis in the run-down state, gravity acts on the washing carriage. He will therefore always rest on the downwardly oriented side of the tilted carousel. If the carousel continues to rotate, the washing car moves on its rollers, so that it rests again on the downwardly oriented side of the carousel. This movement of the washing carriage ensures that the laundry moves and the force of gravity on cleaning liquid remaining in the laundry attacks from different directions and thus causes them to drain. In this embodiment, it may further be provided that less or no clearance between one or more Waschgutaufnahmen, which are mounted on the washing carriage, and the associated laundry is provided. Since the entire wash swarm can move in this embodiment, it is not absolutely necessary that the laundry also moves relative to its Waschgutaufnahme. Thus, the Waschgutaufnahme can be designed so that exact positive connection to the laundry occurs and this is thus immovably taken up in the Waschgutaufnahme.
    In an advantageous embodiment, it is provided that the shape of the Waschgutaufnahme is adapted to the shape of the laundry and the laundry in the tilted relative to the horizontal state of drainage of the wash chamber by acting on the laundry gravity rests on a first side of the Waschgutaufnahme and due the, compared to the outer dimensions of the laundry larger interior dimensions of the Waschgutaufnahme a distance between the laundry and a second side of the Waschgutaufnahme is present. In this embodiment, the shape of the Waschgutaufnahme is adapted to the shape of the laundry, wherein the Waschgutaufnahme is made larger than the laundry. Conveniently, the shape of the Waschgutaufnahme a true-to-scale enlargement of the shape of the laundry by a certain factor. An increase, for example by a factor of 1.1 generates a Waschgutaufnahme which is about 10% larger than the laundry, but has its exact shape. Such a configuration causes the laundry is indeed movable in the Waschgutaufnahme that movement but only to a limited extent and when flying the laundry on the Waschgutaufnähme rests this large area. Typically, the Waschgutaufnahme is designed as a kind of cage to allow a good drainage of the cleaning liquid. This cage is adapted in the best possible way to the shape of the laundry. By this adaptation of the shape of the Waschgutaufnahme to the shape of the laundry is ensured that no pressure peaks occur during gravity-based resting of the laundry and the laundry is thus not damaged.
    In a further preferred embodiment it is provided that the carousel is also rotatable in the tilted to the horizontal state of drainage of the washing chamber to the tilted axis, wherein laundry, which rests by gravity first on a first side of the Waschgutaufnahme in a further rotation of the Carousels then rests on a second side of the Waschgutaufnahme due to gravity and moves when changing between resting on the first page and the second side of Waschgutaufnahme within the Waschgutaufnahme so that liquid contained in undercuts of the laundry, on all sides of Laundry due to gravity expires. By the game or the distance between Waschgutaufnahme and laundry this moves during rotation of the carousel about a tilted axis of rotation due to gravity relative to Waschgutaufnahme. As a result of this movement, gravity attacks liquid in the laundry from different directions and allows it to drain from the laundry. In addition, during the movement of the laundry impulses or bumps between laundry and Waschgutaufnahme, which additionally cause the drainage or shaking off cleaning fluid from the laundry.
    Furthermore, it is provided in a favorable manner that the shape of the Waschgutaufnahme, viewed in a non-tilted state of the wash chamber from the side at the lower end of the Waschgutaufnahme exactly the dimensions of the laundry and the shape of the Waschgutaufnahme at the upper end greater than the dimensions of the laundry is, so that moves at a tilt of the wash chamber, the upper end of the laundry in the upper end of the Waschgutaufnahme due to gravity and the lower end of the laundry in the lower end of the Waschgutaufnahme remains unmoved calm. In this embodiment, the shape of the Waschgutaufnahme is not true to scale enlargement of the laundry. The shape or the proportions of Waschgutaufnahme differ in this embodiment of those of the laundry. As a result, the laundry in different areas of Waschgutaufnahme different degrees of freedom of movement. This different degrees of freedom of movement can be used to optimize the caused by the movement of the laundry draining of cleaning fluid.
    The object of the invention is also achieved by a system having a washing device, in particular according to one of the embodiments described above, further comprising a plurality of washing car, each washing car has at least one Waschgutaufnähme and for different laundry each an adapted washing car with adapted Waschgutaufnähme is provided, wherein it is provided to carry out the loading and unloading of a laundry car with laundry outside the wash chamber, while a washing car filled with laundry is in the wash chamber. A system according to the invention first includes a washing device according to one of the embodiments described above. In addition, several washing car are provided, each of these washing car is customized and specifically adapted to a particular type of laundry. This also means that each washing car gives at least one specially adapted Waschgutaufnahme. For the cleaning of small load carriers more such Waschgutaufnahmen are usually provided on a washing car. In a system according to the invention, the introduction of the laundry into the washing car and the removal of the laundry from the washing car outside the washing device takes place. While loading and unloading the washing carts, another washing car in the washing device may undergo a washing process. An inventive system causes the cleaning of laundry in the washing device can be done almost without interruptions. After completion of a washing process, only the washing car is changed and the washing device immediately reactivated and started a new washing process. Such a system allows a quick and economical cleaning of large numbers of laundry. This is particularly favorable in the cleaning of small load carriers, since these are often used in large quantities. By providing special, adapted to the shapes of the laundry car wash, the risk of damage to laundry is minimized due to this form fit.
    In a further preferred embodiment it is provided that each washing carriage has a plurality of Waschgutaufnahmen, wherein the Waschgutaufnahmen are provided for different subassemblies of a type laundry. Especially in the field of small load carriers, the laundry often has a plurality of individual components, which are combined with each other. Such laundry must be disassembled into its components before the washing process and after the washing process, these items must be reassembled correctly. In order to enable the assignment of the individual parts to each other and a correct reassembly of the assemblies, it is provided in this embodiment that a plurality of Waschgutaufnahmen is attached to a washing carriage and these different Waschgutaufnahmen are adapted to the shape of various subassemblies of the laundry. For the cleaning of such assemblies of laundry, the laundry is first disassembled and placed in adjacently arranged Waschgutaufnahmen in one and the same washing car. Subsequently, after the washing process, the subassemblies are removed again from the adjacently arranged Waschgutaufnahmen and can be reassembled directly without logistic intermediate stages would be required. For example, an assembly of small load carriers from a surrounding box, a lid for closing the box and a plurality of blisters or trays on which the actual product is arranged inside the box. In this case, a washing carriage according to the invention has laundry receptacles for the box, the lid and the blister or trays. Such an assembly of laundry is supplied in the assembled state the washing or cleaning process and leaves it again in the assembled state.
    The object of the invention is also achieved by a system with a washing device which has a washing chamber with at least one washing nozzle arranged therein and a carousel arranged therein, being receivable by the carousel laundry and the carousel is rotatably mounted about an axis, wherein the Washing device is tiltably mounted to the horizontal and a tilting device is provided which tilts the washing device by an angle relative to the horizontal to produce a drain state of the washing device and the carousel has several Waschgutaufnahmen and the system further comprises a plurality of laundry goods, which can be introduced into the Waschgutaufnahmen the outer dimensions of the laundry are made smaller than the inner dimensions of the respective Waschgutaufnahme and thereby play between laundry and Waschgutaufnahme consists and is provided that the laundry within the Waschgutaufnahme during a rotation the carousel moves due to gravity, wherein the movement of the laundry by the Waschgutaufnahme limited so that the laundry does not come into contact with another laundry. This system consists essentially of a smaller laundry, which is arranged in a larger Waschgutaufnahme. Due to the difference in size resulting game between two elements, the laundry is movable within the Waschgutaufnahme.
    However, this mobility is limited, so that the laundry can not leave the Waschgutaufnähme and so can not come into contact with other laundry. The particular advantage of such an inventive system is that the limited freedom of movement of the laundry during cleaning can be used to remove cleaning liquid remaining in the laundry from the laundry. The mechanisms acting thereupon are described above in connection with the description of various embodiments of a washing device according to the invention.
    The object of the invention is further achieved by a method for cleaning laundry, in particular using a washing device or a system according to one of the embodiments described above, comprising the steps - introducing the laundry in Waschgutaufnahmen, the Waschgutaufnahmen are dimensioned larger than the laundry, washing the laundry in a washing chamber of a washing device, wherein the laundry is arranged on a rotating in the washing chamber carousel and is irradiated by at least one washing nozzle with cleaning liquid, tilting of the washing chamber relative to the horizontal, wherein the carousel rotates with the laundry , - Movement of the laundry in the Waschgutaufnahmen, due to the fact that the laundry due to gravity and due to the rotational movement of Waschgutaufnahmen in the tilted wash chamber, at different times on different contact surfaces in the Waschg utaufnahme rests, leaving in undercuts of the laundry left behind cleaning liquid due to gravity. According to a method according to the invention, laundry is cleaned in several successive steps. Particularly advantageous in a method according to the invention is the method step in which the washing device is tilted relative to the horizontal and in this process state the carousel is set into a rotary movement with the laundry. Due to the play-related accommodation of the laundry in larger exported Waschgutaufnahmen arises during rotation of the carousel in the expiration state, a kind of gravitational back and forth traps of the laundry. By this movement and the slight bumps generated between laundry and Waschgutaufnahme remaining cleaning liquid is safely and quickly removed in the laundry.
    Advantageously, it is provided that in addition a spin operation is provided, in which the carousel is rotated with the laundry in a non-tilted and / or tilted state of the wash at a constant or varying angle to remove residual cleaning fluid by centrifugal force from the laundry , In addition, in this embodiment, a spinning operation is provided in which the carousel is rotated at high speed to generate a centrifugal force acting on cleaning liquid remaining in or on the laundry. Such a spinning process can be carried out in the normal position or in a tilted state of the washing machine. Of course, it is also conceivable to carry out a tilting movement of the washing device during the spinning process and thus to superimpose both movements on one another. It is also possible to set or program different, constant tilt angles for the spin cycle, depending on which procedure is most effective for the removal of cleaning fluid for a particular type of laundry.
    In a preferred embodiment it is provided that in addition a blow-off process is provided, in which the laundry is freed from residual cleaning liquid by a flow of air generated by at least one blow-off nozzle when the carousel is stationary or rotating. In this embodiment, an additional process step is employed using a different physical principle. There are provided in the washing device one or more blow-off nozzles, which generate an air flow to the laundry. This air flow acts like a hair dryer and removes additional cleaning fluid that may still be left in or on the laundry. Of course, the spinning process described above can also be combined with a blow-off.

    Fig. 1 shows a sectional side view of an embodiment of a washing device according to the invention without laundry. The entire washing device is on the ground 5 and is partially attached to this. The largest part of the washing device is formed by the washing chamber 1. The washing chamber 1 comprises a housing which encloses most of the components of the washing device. The housing has, inter alia, the task to keep cleaning liquid inside the washing device. Furthermore, the housing of the thermal and acoustic insulation of the washing device is used. Inside the washing chamber 1 four washing nozzles 2 are mounted here, which spray cleaning liquid during the washing process. Of course, a different number of wash nozzles 2 can be installed in the wash chamber 1. The washing nozzles 2 are designed as rotating nozzles, which rotate during the washing process and during the spraying of cleaning liquid. As a result, a better distribution of the cleaning liquid in the interior of the washing chamber 1 is achieved. The washing nozzles 2 can be designed as high-pressure nozzles and dirt on the laundry in addition, in addition to the separation effect of the cleaning liquid, solve by high pressure. But it is also possible to operate the washing nozzles 2 at a lower pressure. This can be advantageous if the laundry is mechanically very sensitive and high-pressure cleaning could lead to damage. The washing nozzles 2 are fixedly mounted in the washing chamber 1. The washing nozzles 2 are here attached to trusses 21. The washing nozzles 2 and the trusses 21 are designed here so that the position of the washing nozzles 2 can be easily adjusted. The washing nozzles 2 can be moved along the trusses 21. On the left side, two washing nozzles 2 are fixed in the lower region of the washing chamber 1, on the right side, the washing nozzles 2 are arranged in the region of the traverse 21. It is also possible to mount horizontally extending trusses 21 and also to arrange at these equal washing nozzles. The number of washing nozzles 2 used can be selected and designed according to the laundry to be cleaned. Approximately in the middle of the washing chamber 1, the carousel 3 is arranged. This carousel 3 has a base plate 33, on which a plurality of vertically upwardly extending struts 34 are fixedly mounted. These struts 34 are connected to each other at the upper end of the carousel 3 several end struts 35. The base plate 33, struts 34 and end struts 35 together form the carousel 3. The carousel 3 is attached to a drive shaft of the carousel drive 36. The carousel drive 36 itself is fixedly attached to the washing chamber 1. The carousel 3 can thus be offset by the carousel drive 36 relative to the washing chamber 1 in a rotational movement about the axis A. This rotational movement serves on the one hand to move the laundry arranged in the carousel 3 relative to the stationary washing nozzles 2. This movement ensures that all areas of the laundry are reached by cleaning fluid. On the other hand, the rotational movement of the carousel 3 can be used to spin off cleaning fluid from the laundry. The rotational movement will be relatively slow during the activity of the washing nozzles 2, whereas in a spinning process which serves to remove liquid from the laundry, a faster rotation is set. Conveniently, the carousel drive 36 is arranged at the top of the washing chamber 1. This ensures that cleaning fluid does not run unintentionally into the carousel drive 36 due to gravity. Of course, the carousel drive 36 can also be arranged elsewhere. Under certain circumstances, however, special measures for sealing the carousel drive 36 are required. Inside the carousel 3, a washing carriage 32 with a total of eight laundry receptacles 31 can be seen. The washing carriage 32 can be introduced into the washing chamber 1 through a door, not shown, and removed from the washing chamber 1 again. The washing carriage 32 is thereby pushed between two struts 34 on the base plate 33 of the carousel 3. The washing carriage 32 is thus positioned inside the carousel 3, whereby the washing carriage 32 performs a rotational movement during rotation of the carousel 3. In the illustrated embodiment, the washing car is fixed after insertion into the washing chamber 1, so that it can no longer move relative to the carousel 3. For this fixation, not shown fixing elements are provided. These fixing elements can be formed for example by straps, clamps or fittings. At the bottom of the washing carriage 32 a plurality of rollers 37 are mounted, on which the washing carriage 32 unrolls during movement. The washing carriage 32 is designed so that it can be moved by a person. On the washing carriage 32 several Waschgutaufnahmen 31 are mounted, which receive the laundry. In Fig. 1, no laundry is contained in the Waschgutaufnahmen 31, the Waschgutaufnahmen 31 are all empty. The Waschgutaufnahmen 31 are conveniently designed as cages. By a design as a cage, the laundry is securely held and guided and at the same time cleaning fluid can reach the laundry with little resistance and run off of this again. On the left side of the washing chamber 1, the tilting device 4 can be seen. The tilting device 4 is designed here as a hydraulic cylinder, whose lower end is fixed to the substrate 5. The extendable piston rod of the tilting device 4 is attached approximately in the middle of the height of the washing chamber 1 at this. At the bottom right on the border of the washing chamber 1 to the substrate 5, the tilting axis 41 can be seen. This tilting axis 41 extends into the plane of the drawing. By means of the tilting device 4 and the tilting axis 41, the washing device can be converted into a tilted discharge state. During the transition to the drain state, the piston rod moves out of the tilting device 4 and presses the wash chamber 1 first upwards. In this case, the entire washing chamber 1 rotates with its entire contents around the tilting axis 41 arranged on the opposite side of the washing chamber. The tilted discharge state of the washing device is shown in FIGS. 3 and 4.
    Fig. 2 shows a sectional side view of an embodiment of a washing device according to the invention with laundry. Fig. 2 is largely identical to Fig. 1, but is introduced in all eight Waschgutaufnahmen 31 laundry. The laundry is shown in black throughout. The introduction of laundry in the Waschgutaufnahmen 31 takes place when the washing carriage 32 is not in the washing chamber 1. The Waschgutaufnahmen 31 are designed so that laundry can be initially introduced and then fixed in the Waschgutaufnahmen 31. For this purpose, the laundry receptacles 31 may have a closable lid on one side. To remove the laundry from the Waschgutaufnahmen 31 of the closable lid is then opened again. The shape and size of the Waschgutaufnahmen 31 is adapted to the shape and size of the respective laundry. In Fig. 2 several different types of laundry are seen, which differ in shape and size from each other. For each type of laundry a specially adapted Waschgutaufnahme 31 is provided. At the top right of the washing carriage 32 is a long narrow laundry in a corresponding Waschgutaufnahme 31 is introduced. The laundry may be, for example, a lid for a small load carrier. Directly below a larger, more voluminous laundry is arranged in a suitably adapted Waschgutaufnahme 31. This may be, for example, a repacking box of a small load carrier. An advantage of an adjacent arrangement of different types of laundry is that after the washing process belong together parts, such as in the example box with matching ceiling, removed in the same handle and can be reassembled. This facilitates the loading and unloading of laundry and ensures that the parts or subassemblies can be properly assigned to each other again in the case of multi-part laundry. In Fig. 2 it can be clearly seen that the inner dimensions of the Waschgutaufnahmen 31 are slightly larger than the outer dimensions of the respective laundry. There is thus a play between the laundry and its Waschgutaufnahme 31. It has been found to be particularly advantageous to perform the shape of the Waschgutaufnahme 31 as a true-to-scale enlargement of the shape of the laundry. Favorable is an embodiment in which a game in the range of a few centimeters, in particular between 1 and 5 cm between laundry and Waschgutaufnahme 31 is. Of course, a larger game can be provided. The advantages of a distance or a game between laundry and Waschgutaufnahme 31 are clear in the following figures.
    Fig. 3 shows a sectional side view of an embodiment of a washing device according to the invention with laundry in the drain state. Fig. 3 shows the washing device shown in Fig. 2 with laundry in the drain state. Starting from the basic position of the washing device shown in FIG. 2, the piston rod of the tilting device 4 designed as a hydraulic cylinder for the transfer of the washing device into the state of drainage shown in FIG. 3 has been extended. The wash chamber was tilted about the tilt axis 41 relative to the horizontal. Between axis A and the horizontal and the vertical side wall of the washing chamber and the horizontal of the identical angle α is located. This angle oc is in the basic position of the washing device shown in Fig. 2 90 °. In the tilted process state in Fig. 3, this angle α is now smaller than 90 °. For the process state, different sized and varying angles α are possible. In the run state is also the axis A, which rotates the rotation of the carousel 3 is tilted. At Waschwagen 32 more Waschgutaufnahmen 31 are attached. The function of a washing device according to the invention will now be explained using the example of the laundry, which is located on the left side of the washing carriage in the second-highest Waschgutaufnahme 31. This laundry is the largest in the washing cart 32 and could be formed, for example, by a box of a small-capacity carrier. Between the laundry and the Waschgutaufnahme 31 is game, so that the laundry can move within the Wäschgutaufnähme 31. In the illustrated state, the force of gravity acts on the laundry, so that this rests on the right bottom oriented side of the Waschgutaufnahme 31. This oriented to the bottom right side is still oriented vertically in the basic position shown in Fig. 2. In the situation shown in FIG. 3, cleaning fluid can now flow out of undercuts due to gravity, which may possibly be present on the side of the laundry to be oriented to the bottom right. This was not possible in the vertical orientation in FIG. The laundry is in Fig. 3 on the right bottom oriented side, which is oriented in this case to the interior of the carousel 3.
    Fig. 4 shows a sectional side view of an embodiment of a washing device according to the invention with laundry in the drain state with rotated carousel. Fig. 4 corresponds to FIG. 3 with the difference that the carousel 3 has been noted by 180 ° about the axis A on. The in Fig. 3 on the left side in the second highest Waschgutaufnahme 31 housed, largest laundry is now on the right side of the carousel 3. Gravity due to the laundry is again on the bottom right side, but which now represents the side directed from the carousel 3 outwards. Thus, in Fig. 4, the opposite side of the laundry is oriented to the bottom right, compared with the state in Fig. 3. In Fig. 4, only by gravity cleaning fluid from undercuts from the opposite side of the laundry occur. As a result of a further rotation of the carousel 3 about the axis A, all sides of the laundry are alternately brought into a position in which cleaning fluid can drain from or out of the laundry due to gravity. The game or the distance between the laundry and the laundry now provides another, the drainage of cleaning fluid favoring effect: The rotation of the laundry around a tilted axis causes the laundry to go through every single rotation a highest point on its path. Until it reaches this highest point, the laundry is due to gravity on a first side on the Waschgutaufnahme 31. When the highest point is exceeded, the gravitational force now acts in the opposite direction, so that the laundry falls on an opposite second side of the laundry receptacle 31. As a result of this falling over, when the laundry is being hit on the second side, a mechanical impulse is created which ensures that the washing material is knocked off or shaken off from the laundry. The greater the game between laundry and laundry 31 is selected, the more the laundry falls with each revolution of the carousel 3 on its second page. The greater the distance of the fall, the greater is the momentum created by the impact. Thus, the strength of the impact of the laundry can be adjusted by the size of the game. It makes sense not to over-adjust the service charge so that the laundry is not damaged. In the run state, the carousel 3 is moved at a low rotational speed, so that the described back and forth falling of the laundry in his Waschgutaufnahmen 31 actually takes place. If the rotational speed is increased, centrifugal forces additionally act on the laundry, which prevent a gravitational falling over of the laundry. It would also be possible to first rotate the carousel 3 at low speed in the run-down state and to increase the rotational speed shortly before the end of the washing process in order to additionally use a centrifugal effect to remove cleaning fluid from the laundry.
    Fig. 5 shows a sectional side view of an embodiment of a washing device according to the invention with extended Waschgutaufnahmen. In this embodiment, the shape of the Waschgutaufnahmen 31 no longer corresponds to a true-to-scale enlargement of the shape of the laundry. Rather, the game in the upper part of the Waschgutaufnahmen 31 to the laundry is significantly larger than in the lower area. In the illustrated in Fig. 3 and 4 rotation in the drainage state moves in the embodiment shown in Fig. 5, only the upper end of the laundry moves due to gravity, whereas the lower end dwells in its position. This embodiment causes a larger range of movement of the laundry in the upper area. As a result, larger Verkippungswinkel the laundry are achieved, which in turn favors the gravity-induced drainage of cleaning fluid. At the same time, the relatively narrow guide in the lower area ensures that when the laundry is being hit on its second side, no excessive impulse occurs and thus the risk of damage to the laundry is low.
    6 shows a sectional side view through an embodiment of a washing device according to the invention with blow-off nozzles. There may be occurrences of deep undercuts on the upwardly oriented side of the laundry, from which not all of the cleaning liquid alone can be removed by the above-described drainage condition and rotation about a tilted axis. In the embodiment of a washing device shown in FIG. 6, two blow-off nozzles 6 are attached to the top of the washing chamber 1. The outlet openings of these blow-off nozzles 6 are here directed to the upwardly oriented side of the laundry and blow air under pressure on the laundry. The air flow thus generated removes remaining cleaning fluid from undercuts in the laundry. Of course, blow-off nozzles 6 may also be attached to other locations of the washing chamber 1, which may also be directed to other sides of the laundry. The embodiments of a washing device shown in various figures can of course be freely combined with each other, so that all possible combinations are disclosed with.
    Fig. 7 shows a sectional side view through an embodiment of a washing device according to the invention with a movable washing carriage. The embodiment illustrated in FIG. 7 has essentially two differences from the embodiment shown in FIG. 2: In FIG. 7, there is no play between the laundry and the associated laundry receptacle 31. The laundry is inserted into the respective laundry receptacle 31 in a form-fitting and immovable manner. Thus, the laundry can not move due to gravity on rotation about a tilted axis in the drainage state. As compensation for this, the entire washing carriage 32 is not fixed to the carousel 3 as in FIG. 2, but can move within the carousel 3. In the illustrated state, the washing carriage 32 is located on the far right side of the carousel 3. To the left side of the carousel there is a distance 321. If now the washing device tilted and transferred to the flow state, the entire washing car is initially due to gravity continue on the right Side of the carousel. Now, if the carousel is rotated, the entire washing car moves up and finally falls or rolls gravity on the opposite side of the carousel. This creates an impact between the entire washing car and the carousel, which in turn ensures a shaking off of cleaning liquid from the laundry. In the embodiment shown in Fig. 2 thus arises during rotation about a tilted axis regularly a collision of each individual laundry on his Waschgutaufnahme 31, whereas in the embodiment shown in Fig. 7 there is a regular impact of the washing carriage 32 with the entire laundry. In both cases, a mechanical impulse occurs on the laundry, which is useful in removing residual cleaning liquid from the laundry.
