Description

The invention relates to a device for cleaning laundry, comprising at least one washing chamber with at least one closable opening for insertion and / or removal of the laundry, at least one row of nozzles inside the washing chamber and at least one receiving device in the interior of the washing chamber, in the at least two laundry items, preferably a stack of laundry items, in particular from each other vertically spaced washing levels can be suspended. In this case, the receiving device has a distance changing device, by means of which the distance between the at least two laundry items or wash levels can be changed.

Such devices for cleaning laundry are known. To achieve particularly thorough washing results, some washing devices are equipped with a distance changing device. This makes it possible to introduce several laundry items, such as pallets, as a stack in the washing device. During the washing process, this stack is then dissolved, in which the distance changing device increases the vertical distance between two adjacent Waschgutelementen. This increased distance allows a thorough cleaning even at the places that are covered by stacked laundry items from the adjacent elements. Known washing devices are designed so that the stack of laundry is introduced at ground level into the device. The change in the distance between the laundry items then takes place with the aid of a distance changing device, which increases the distance between the individual laundry items for the washing process by means of several compression springs. A disadvantage of such washing devices is that the distance changing device has many individual parts. This requires a relatively long construction time. Furthermore, an adjustment of the distance between the laundry items takes a lot of time due to the many items. Finally, with the use of compression springs there is a certain risk of injury to the machine operator due to uncontrollably expanding springs, if a breakage of a component occurs in the device.

Based on this prior art, it is an object of the invention to propose a solution in which the change in the distance between two adjacent Waschgutelementen is simplified.

• - wenigstens eine Waschkammer mit zumindest einer verschließbaren Öffnung zum Einlegen und/oder zur Entnahme des Waschgutes,
• - wenigstens eine Reihe von Düsen im Inneren der Waschkammer, aus denen Reinigungs- und/oder Spülflüssigkeit auf das Waschgut geleitet, insbesondere mit Druck auf das Waschgut gestrahlt wird,
• - wenigstens eine Aufnahmevorrichtung im Inneren der Waschkammer, in die wenigstens zwei Waschgutelemente, vorzugsweise ein Stapel von Waschgutelementen, in voneinander insbesondere vertikal beabstandeten Waschebenen einhängbar ist,

wobei die Aufnahmevorrichtung eine Abstandsveränderungsvorrichtung aufweist, mittels derer der Abstand zwischen den wenigstens zwei Waschgutelementen beziehungsweise Waschebenen veränderbar ist, wobei die Abstandsveränderungsvorrichtung ein Gestell aufweist, an dem wenigstens zwei relativ zum Gestell verfahrbare, eine Mitnahme für die Abstandsveränderungsvorrichtung zur Verfügung stellende Hebevorrichtungen und ein mit den Hebevorrichtungen verbundenes Zugmittel vorgesehen sind, wobei das Zugmittel die Hebevorrichtungen im Beschickungszustand hängend zusammenhält und das Zugmittel die Waschgutelemente in der Waschstellung vereinzelt und eine Längenänderungsvorrichtung vorgesehen ist, welche die wirksame Länge des Zugmittels beim Wechsel vom Beschickungszustand zur Waschstellung und umgekehrt verändert. Eine erfindungsgemäße Vorrichtung umfasst zumindest eine Waschkammer mit einer verschließbaren Öffnung. Bevorzugt ist diese verschließbare Öffnung dabei als Tür ausgeführt, wobei diese Tür einen oder mehrere Türflügel aufweisen kann. Die Öffnung kann selbstverständlich auch anders ausgeführt sein, beispielsweise als entnehmbarer Deckel. Günstig ist es dabei Schnittstelle zwischen Waschkammer und verschließbare Öffnung flüssigkeitsdicht auszuführen, damit beim Waschvorgang keine Reinigungsflüssigkeit austreten kann. Die verschließbare Öffnung ist für das Einbringen und die Entnahme des Waschgutes vorgesehen. Weiterhin umfasst eine erfindungsgemäße Vorrichtung zumindest eine Reihe von Waschdüsen im Inneren der Waschkammer, welche zur Reinigung des Waschgutes dienen. Aus diesen Reinigungsdüsen wird bevorzugt unter hohem Druck Reinigungsflüssigkeit auf das Waschgut gespritzt, wodurch dieses gereinigt wird. Weiterhin umfasst eine erfindungsgemäße Vorrichtung zumindest eine Aufnahmevorrichtung im Inneren der Waschkammer, in die wenigstens zwei Waschgutelemente, vorzugsweise ein Stapel von Waschgutelementen, in voneinander insbesondere vertikal beabstandeten Waschebenen einhängbar ist. Diese Aufnahmevorrichtung nimmt die einzelnen Elemente des Waschgutes während des Waschvorgangs in der Vorrichtung auf. Die einzelnen Waschgutelemente werden bei der Aufnahme durch die Aufnahmevorrichtung in verschiedenen Waschebenen eingehängt oder eingeschoben. Unter Aufnahmevorrichtung ist hier eine Baugruppe zu verstehen, welche im Inneren der Vorrichtung angeordnet ist und mehrere Unterbaugruppen aufweist. Eine dieser Unterbaugruppen wird durch eine Abstandsveränderungsvorrichtung gebildet, mittels derer der Abstand zwischen den wenigstens zwei Waschgutelementen beziehungsweise Waschebenen veränderbar ist. Diese Abstandsveränderungsvorrichtung dient dazu, den Abstand zwischen zwei benachbarten Waschgutelementen zu verändern, insbesondere für die Durchführung des Waschvorganges zu vergrößern und nach Beendigung des Waschvorganges wieder zu verkleinern. Die Abstandsveränderungsvorrichtung weist dabei ein Gestell auf welches zumindest zum größten Teil innerhalb der Waschkammer angeordnet ist. An diesem Gestell Sind zumindest zwei, bevorzugt aber mehrere Hebevorrichtungen angeordnet. Diese Hebevorrichtungen sind relativ zum Gestell verfahrbar, insbesondere in vertikaler Richtung. Die Hebevorrichtungen nehmen die Waschgutelemente auf, im Normalfall wird je ein Waschgutelement von einer Hebevorrichtung aufgenommen. Es ist aber auch denkbar, dass eine Hebevorrichtung mehrere Waschgutelemente aufnimmt. Die Hebevorrichtungen können wiederum aus mehreren Unterbaugruppen aufgebaut sein. Weiterhin weist die Abstandsveränderungsvorrichtung ein Zugmittel auf, welches an einem Ende mit den Hebevorrichtungen verbunden ist. Das Zugmittel dient der Veränderung des Abstandes zwischen den einzelnen Hebevorrichtungen. Dabei hält das Zugmittel die Hebevorrichtungen im Beschickungszustand zusammen, wobei in diesem Zustand alle Hebevorrichtungen an den Zugmittel hängen. In der Waschstellung wird die wirksame Länge des Zug mittels vergrößert, so dass das Zugmittel die Hebevorrichtungen nicht mehr hängend zusammenhält, sondern vereinzelt, so dass Abstände zwischen den einzelnen Hebevorrichtungen bzw. Waschgutelementen entstehen. Unter wirksamer Länge ist die Länge desjenigen Teils des Zugmittels zu verstehen, welche direkt auf die Schiebeelemente einwirkt und deren Abstand zueinander steuert. Das Zugmittel weist eine Gesamtlänge auf, die länger ist als die wirksame Länge. Die Gesamtlänge des Zugmittels Erstreckt sich von einem Endpunkt des Zugmittels zum anderen, wobei einer der Endpunkte mit zumindest einer Hebevorrichtung verbunden ist und der andere ein an verschiedenen Orten an oder in der Vorrichtung befestigt ist. Die Gesamtlänge des Zugmittels ergibt sich aus der wirksamen Länge und einer Restlänge des Zugmittels, auf welche eine Längenänderungsvorrichtung einwirkt. Die Längenänderungsvorrichtung drückt beispielsweise auf die Restlänge des Zugmittels und vergrößert so diese Restlänge, wodurch die wirksame Länge des Zugmittels verkleinert wird. Durch eine Verkleinerung der wirksamen Länge des Zugmittels werden die Hebevorrichtungen aneinander gezogen und so deren Abstand zueinander verringert. In umgekehrter Richtung kann die Längenänderungsvorrichtung die Restlänge des Zugmittels verkürzen und dadurch die wirksame Länge des Zugmittels vergrößern, so dass sich der Abstand zwischen den Hebevorrichtungen ebenfalls vergrößert. Die Längenänderungsvorrichtung tritt vor allem bei einem Wechsel von Beschickungszustand zur Waschstellung und umgekehrt in Aktion um die Abstände zwischen den Hebevorrichtungen und damit zwischen den an den Hebevorrichtungen angebrachten Waschgutelementen zu verändern. Als Zugmittel kommen dabei zunächst flexible, seilartige Elemente infrage. Besonders günstig für das aggressive Milieu in einer Waschvorrichtung haben sich Ketten herausgestellt. Selbstverständlich kann das Zugmittel aber auch durch Seile oder Riemen gebildet werden. Alternativ zu einem flexiblen Zugmittel kann auch ein starres Zugmittel, beispielsweise in Form einer Stange, insbesondere einer Metallstange vorgesehen werden. Die Längenänderungsvorrichtung ist entsprechend der Ausführung des Zugmittels gestaltet, bei der Verwendung eines flexiblen Zugmittels beispielsweise als Arbeitszylinder, der auf die Restlänge des Zugmittels einwirkt. Im Falle eines starren Zugmittels kann die Längenänderungsvorrichtung auch als angetriebenes Zahnrad ausgeführt sein, welches in eine entsprechende Gegenverzahnung an einem beispielsweise stangenförmigen Zugmittel eingreift und durch eine Drehbewegung dessen wirksame Länge verändert. Das Zugmittel kann auch als Gewindespindel ausgeführt sein, wobei die Längenänderungsvorrichtung dann als angetriebene Mutter oder Muffe ausgeführt ist, welche durch eine Rotation eine lineare Bewegung des als Gewindespindel aufgeführten Zugmittels bewirkt.This object of the invention is achieved by a device for cleaning laundry, comprising a feed state and a washing position for the laundry

• at least one washing chamber with at least one closable opening for insertion and / or removal of the laundry,
• at least one row of nozzles in the interior of the washing chamber, from which cleaning and / or rinsing liquid is directed onto the laundry, in particular by blasting with pressure on the laundry,
• at least one receiving device in the interior of the washing chamber, into which at least two items of laundry items, preferably a stack of items to be washed, can be suspended in wash planes spaced apart from one another, in particular vertically,

wherein the receiving device comprises a distance changing device, by means of which the distance between the at least two Waschgutelementen or wash planes is variable, wherein the distance changing device comprises a frame, on which at least two movable relative to the frame, a driving for the distance changing device providing lifting devices and with the Lifting devices connected traction means are provided, wherein the traction means holds the lifting devices in the loading state hanging together and the traction means the laundry items in the washing position separated and a length change device is provided which changes the effective length of the traction means when changing from the feed state to the washing position and vice versa. A device according to the invention comprises at least one washing chamber with a closable opening. Preferably, this closable opening is designed as a door, said door may have one or more doors. The opening can of course also be designed differently, for example as a removable cover. It is advantageous to carry out liquid-tight interface between wash chamber and closable opening so that no cleaning liquid can escape during the washing process. The closable opening is provided for the introduction and removal of the laundry. Furthermore, a device according to the invention comprises at least one row of washing nozzles in the interior of the washing chamber, which serve to clean the laundry. From these cleaning nozzles, cleaning liquid is preferably sprayed onto the laundry under high pressure, whereby it is cleaned. Furthermore, a device according to the invention comprises at least one receiving device in the interior of the washing chamber, into which at least two items of laundry items, preferably a stack of laundry items, can be suspended in washing levels spaced apart from each other, in particular vertically. These Receiving device receives the individual elements of the laundry during the washing process in the device. The individual laundry items are suspended or inserted in the recording by the recording device in different wash levels. Under recording device is here to understand an assembly which is arranged in the interior of the device and has a plurality of subassemblies. One of these subassemblies is formed by a distance changing device, by means of which the distance between the at least two laundry items or wash planes is variable. This distance changing device is used to change the distance between two adjacent Waschgutelementen, in particular for the implementation of the washing process to enlarge and to reduce again after completion of the washing process. The distance changing device in this case has a frame which is arranged at least for the most part within the washing chamber. At least two, but preferably a plurality of lifting devices are arranged on this frame. These lifting devices are movable relative to the frame, in particular in the vertical direction. The lifting devices pick up the laundry items, normally a laundry item is picked up by a lifting device. But it is also conceivable that a lifting device receives several laundry items. The lifting devices may in turn be constructed of several subassemblies. Furthermore, the distance changing device has a traction means, which is connected at one end to the lifting devices. The traction means is used to change the distance between the individual lifting devices. In this case, the traction means keeps the lifting devices together in the loading state, in which state all the lifting devices hang on the traction means. In the washing position, the effective length of the train is increased by means of, so that the traction device no longer holds the lifting devices together, but isolated, so that distances between the individual lifting devices or Waschgutelementen arise. Effective length is to be understood as the length of that part of the traction means which acts directly on the sliding elements and controls their distance from each other. The traction means has an overall length which is longer than the effective length. The total length of the traction means extends from one end point of the traction means to the other, one of the end points being connected to at least one lifting device and the other being fixed to different locations on or in the device. The total length of the traction means results from the effective length and a residual length of the traction means, which acts on a length change device. The length change device presses, for example, on the remaining length of the traction device and thus increases this residual length, whereby the effective length of the traction device is reduced. By reducing the effective length of the traction device, the lifting devices are pulled together, thus reducing their distance from each other. In the opposite direction, the length-changing device can shorten the remaining length of the traction means and thereby increase the effective length of the traction means, so that the distance between the lifting devices also increases. The length change device occurs mainly in a change from the loading state to the washing position and vice versa in action to change the distances between the lifting devices and thus between the attached to the lifting devices Waschgutelementen. As traction means come initially flexible, rope-like elements in question. Chains have proven to be particularly favorable for the aggressive environment in a washing device. Of course, the traction means can also be formed by ropes or belts. As an alternative to a flexible traction means, it is also possible to provide a rigid traction means, for example in the form of a rod, in particular a metal rod. The length-change device is designed according to the design of the traction means, when using a flexible traction means, for example, as a working cylinder, which acts on the residual length of the traction means. In the case of a rigid traction device, the length-changing device can also be designed as a driven gear, which engages in a corresponding counter-toothing on an example rod-shaped traction means and changes its effective length by a rotational movement. The traction means may also be designed as a threaded spindle, wherein the length-changing device is then designed as a driven nut or sleeve, which causes by a rotation of a linear movement of the traction means listed as a threaded spindle.

In a preferred embodiment it is provided that the lifting devices are interconnected by spacer elements and the spacer elements are designed to be displaceable relative to at least one lifting device, wherein the lifting devices rest on each other in the loading state and determine the spacing elements in the washing position, the vertical distance of the lifting devices to each other. In this embodiment, the individual lifting devices are interconnected by spacer elements. In the loading state, the lifting devices lie on each other, so that the spacer elements are not needed and are located within the lifting devices. The spacer elements are designed so that they are firmly attached to a lifting device, whereas they are designed to be displaceable at least in a certain range in the adjacent lifting device. This will cause the spacers in the Charging state completely inserted into the adjacent lifting device. When changing to the washing state, the distance between the lifting devices is increased. The displaceably mounted part of the spacer elements is pulled out of the one lifting device when increasing the distance between two lifting devices. At the distance elements an end stop is provided at the end of the displaceably mounted side, which strikes after the partial withdrawal of the spacer element on the lifting device and from this stop further displacement of the spacer to the lifting device is no longer possible. The length of the spacer defined in this state, the distance between two adjacent lifting devices.

Clever way is provided that the length of the spacer elements is made adjustable. In this embodiment, the length of the spacer elements is adjustable, whereby the distance between two adjacent lifting devices is adjustable. This has the advantage that the device can be adapted to laundry items with different dimensions. If laundry items are washed with greater height so the length of the spacers can be increased whereby then the distance between the lifting devices is increased. Of course, the same applies to the adaptation to laundry items with a lower height.

In an advantageous embodiment it is provided that the spacer elements comprise a threaded bolt which is adjustably mounted on a first lifting device and the threaded bolt is movably guided in a bore of the vertically adjacent second lifting device, wherein the threaded bolt on the side located in the second lifting device an end stop and this end stop is designed to be adjustable and fixable in its position on the threaded bolt. In this embodiment, the spacer elements are essentially formed by threaded bolts. Under threaded bolts are also screws with a head to understand. Conveniently, the threaded bolt is firmly bolted to a first lifting device. This screwing can be done with the help of a nut or directly into a thread on the lifting device. The part facing away from this attachment is movably mounted in a bore or a sleeve in the adjacent second lifting device, so that a movement between the spacer element and the second lifting device is possible. Finally, the threaded bolt has an end stop at its end which is fixedly attached to the end. This end stop comes with the adjacent second lifting device in contact as soon as the maximum desired distance between the lifting devices is reached. The end stop is designed so that it can be changed in its position or position on the threaded bolt. A simple embodiment of such an end stop is a screwed onto the threaded bolt nut, which is fixed with a further lock nut in position. Of course, the end stop can also be carried out in other ways. The adjustment of the lifting devices to different heights of the laundry items described in the previous paragraph can be done by changing the position of the end stop on the threaded bolt.

In a further preferred embodiment, it is provided that the traction means is connected by a coupling element with the lowest lifting device seen in the vertical direction. In this embodiment, the traction means is connected by a coupling element with the bottom of the lifting devices. Such a coupling element may for example be designed as an L-shaped angle, one leg of which is fastened to the lifting device and on whose other leg one end of the train is fastened by means. The fact that the train acts by means of so directly only on the lowest lifting device, a simple construction of the distance changing device is made possible. If, starting from the washing position, the distance between the lifting devices is to be reduced, the pulling means only pulls on the lowermost lifting device. As a result, initially the distance between the lowermost and the second lowermost lifting device is reduced until these two lifting devices rest on one another. From this point, further pulling on the pulling means causes movement of the lowermost and second lowermost lifting devices towards each other in the direction of the third lowermost lifting device until it rests against the next lifting device again. This process continues until all lifting devices are resting on each other and the loading condition has been reached. This simple construction is inexpensive to manufacture and very reliable in operation. If, conversely, starting from the charging state, the washing position is taken, the effective length of the train is gradually increased by means of. In this case, first the distance between the uppermost and the second uppermost lifting device begins to increase, wherein the spacer elements are pulled with their displaceable part of one of the lifting devices, until the end stop of the spacer elements is reached. From this point on, the distance between these two lifting devices can not be further increased. In a further increase in the effective length of the train by means of now the distance between the next two lifting devices begins to be larger, until as long as the end stop of the spacer elements is reached. Upon further enlargement of the effective length of the traction means, all distances are gradually increased from top to bottom, until the washing position is reached. When loaded, the lifting devices thus hang in an upper region of the device and move downwards when taking up the washing position. This raised position of the lifting devices in the loading state is initially on the first thought of disadvantage, because what is well supposedly more difficult to be introduced into the device. Surprisingly, it has been found that the position of the lifting devices further up is advantageous for the introduction of the laundry, since the laundry can be easily introduced so easily with a forklift. The view of the laundry located further up is much better than when the forklift driver has to position the laundry on the floor of the device. Due to the better view of the laundry sinks the risk of damage when introduced into the device significantly. Furthermore, if residual moisture remains in the laundry after washing, it drips down, resulting in a further improvement of the washing result.

Furthermore, it is provided in a favorable manner that the length-changing device comprises a guide roller and a linear drive and the traction means its end facing away from the lifting devices is fixedly attached to the device for cleaning laundry and between the point of stationary attachment and attachment to the lifting devices on the Guide roller is guided, wherein a movable releaser of the linear drive acts on the region of the traction means, which is located between the location of the fixed attachment and the deflection roller, whereby the effective length of the traction means is changed. In this embodiment, one end of the traction means is attached to one of the lifting devices, the other end of the traction means is fixedly secured to the device. Furthermore, a deflection roller is provided, which is also fixedly secured to the device. Starting from the end which is attached to the lifting device, the traction means is first guided over the deflection and then runs to the stationary position in the device. The length change device further comprises a linear drive with a releaser. The linear drive is fixedly mounted on the device and the release of the linear actuator acts on the region of the train by means of which runs between the guide roller and the point of fixed attachment to the device. This part of the traction means is defined in this embodiment as a residual length, the effective length of the traction means extends from the deflection roller to the point of attachment of the traction means to the lifting device. The fact that the releaser acts on the residual length of the traction means, this residual amount is increased or decreased and vice versa, the effective length of the traction device is reduced or increased. Preferably, the linear drive is arranged so that it is located outside the wash chamber and so there is no possibility that it is damaged by liquid in the washing, rinsing or drying process. With appropriate sealing, the linear drive can of course also be arranged in the interior of the chamber. In the feed state, in which the distances between the lifting devices are minimal, the effective length of the traction means is minimal, whereas the remaining length of the traction means is maximally large. The aligner of the linear actuator is in this case completely extended. For a change in the washing position of the aligner of the linear drive is moved back which means the remaining amount of the train shortened means and increases the effective length of the train means. This increases, as described above, the distances between the lifting devices. Of course, the length-changing device can also be designed differently.

For example, a kind of winch can be provided which up or unwinds the remaining length of the train and thus reduces or increases the effective length of the traction device. Of course, other embodiments of a length change device which change the effective length of the traction means associated with the invention.

In a further preferred embodiment it is provided that the length-changing device comprises a deflection roller and a linear drive with a movable releaser and the traction means is fixed at its end facing away from the lifting devices on the releaser and the traction means between the point of attachment to the releaser and the attachment to the Lifting devices is guided over the pulley and the effective length of the traction means is changed by the movement of the releaser. This embodiment is similar to the previously described embodiment. However, the traction means is fixed here at its, the lifting devices facing away from the end of the linear actuator directly. By this attachment, the linear movement of the releaser affects directly on the effective length of the traction means. When extending the releaser, the remaining length of the traction device increases, the effective length of the traction device is reduced by the deflection over the pulley and thus pulled the lifting devices upwards. Conversely, a retraction of the releaser in the linear drive causes an increase in the effective length of the traction means and thus a lowering of the lifting devices.

Advantageously, it is provided that the washing chamber encloses at least the distance changing device, the lifting devices and the traction means, wherein the closable opening is formed as a door, which is designed to be liquid-tight to the washing chamber in the closed state. In this embodiment, an enclosing housing prevents washing liquid from leaking out of the device. Conveniently, the wash chamber is designed so that it encloses all elements of the distance changing device. Alternatively, the washing chamber may also be designed so that it encloses only parts of the distance changing device and further parts of the distance changing device protrude from it.

In a preferred embodiment it is provided that the washing chamber has a liquid-tight floor area, wherein the vertical height of the floor area is defined by the height of a lintel and the lintel in the loading state and in the washing position has the same height. In this embodiment, a liquid-tight portion of the washing chamber is provided. This liquid-tight floor area is not interrupted by closable openings but is made invariable. This has the advantage that the security against leakage of washing liquid is improved over a variant with variable openings. The fact that the lifting devices are arranged in the upper region of the device in the feed state, the height of the floor area and thus the height of the lintel are made significantly larger than in a device in which the laundry inserted at ground level on the bottom of the device and attached to the lifting devices becomes. With such a device thus executed, there is no need for a ground-level introduction opening for the laundry and the height of the lintel can be increased. Thus, the floor area compared to conventional washing systems on a higher, completely liquid-tight volume, which ensures the security against the leakage of washing liquid in that the volume in the wash chamber holds the washing liquid used almost three times.

It is possible, by means of a stacker or by automatic placement also from memory locations or the like to introduce a stack of goods to be washed into the device. In the stacked state, these objects to be cleaned of course, one above the other, that is, they lie on each other. If the laundry in the device, that is, placed in the wash chamber, it is then possible to increase the distance between the individual Waschgutelementen or the different washing levels by means of the distance changing device. After fixing the Waschgutelemente it is then possible to initiate the washing process, as usual. In this case, for example, the laundry, which is optionally arranged on a rotating device, placed in a slow rotational movement and acted upon from the outside by the corresponding nozzle with appropriate detergent. This is done in a known manner. After washing can then follow a drying process, which is carried out either as a spinning process with a fast rotary motion or by, for example, blown through a fan warm air into the wash chamber to clean the laundry. Of course, both measures can also be coupled according to the invention. Of course, the effect is even higher. After the first drying, the rinsing process can be carried out in the usual way, for example by rinsing the objects to be cleaned being cleaned once more. Thus, the corresponding detergent residues are completely eliminated. After washing, then again the drying process, either as a spin and / or as a spin and drying process by means of blower.

The invention is characterized according to an advantageous development in that at least two receiving elements are provided on or in the receiving device, wherein the receiving elements are preferably formed like a fork or pike. Similar to the forks of a forklift, therefore, at least two receiving or inserting elements can be arranged one above the other here. Of course, it is preferred that a plurality of such receiving or inserting elements are arranged one above the other in order to be able to clean significantly more laundry in a washing process. Of course, the invention is not limited to a forked or pike-like design. Other edition variants are quite possible. For example, it would also be possible to hang the elements to be washed on certain suspensions which are arranged in the respective washing plane. Also, intake angle as the lowest fork carriage are a way to respond to the variety of tasks.

The invention is also distinguished by the fact that, in particular, stackable pallets, baskets, containers open on one side or the like are provided as laundry items. This also includes, in particular, items of laundry items which are formed by containers which are closed in a planar manner and / or provided with openings or apertures, which, for example, have a latticed or sieve-like design on at least one side. Such laundry items are used in industry, especially in the food industry or in the refrigeration industry often used and must therefore be cleaned again after the intended use, so that they can be fed to a new use. The materials are different, such as metal, plastic and / or composite materials or the like.

By means of the solution according to the invention, it is also possible to wash a wide variety of items of laundry items simultaneously in one apparatus and, in particular, in a single washing operation. That is, the user of the device is no longer required to comply with certain formats and / or profiles or dimensions. In the individual washing levels, it is possible to arrange a wide variety of laundry items.

The device is characterized according to a development also by the fact that the drive of the device is connected simultaneously with a safety switch of the closable opening of the washing chamber, so that only in the closed state of the washing chamber of the washing or cleaning process can be initiated. This too is a precautionary measure designed to prevent accidents. Thus, for example, it can not happen that the device goes into operation without the opening of the washing chamber is closed. Otherwise, it could well happen that a worker standing in front of the device would be injured by the cleaning liquid. To avoid this, this additional fuse variant with a fuse switch, which is connected to the drive, is provided.

According to a variant of the invention, the washing rack provided there is arranged on a carousel in the washing chamber, which can be set into a rotational movement. This washing rack is advantageously designed so that it is adapted in its dimensions to be washed Good or the dimensions of the goods to be washed. The rotational movement is provided as a relatively slow rotational movement for the washing and rinsing process, while a fast rotational movement in the form of a centrifugal movement is provided for the drying process. Usually, one achieves these different rotational movements by appropriate motors or by the interposition of a transmission with different switching stages.

Accordingly, a drive is provided according to the invention, which is able to put the carousel in a rotational movement with at least two different speeds, so that both a relatively slow washing rotary motion, but also a very fast spin movement is possible.

Advantageously, a drying device is also provided in the device according to the invention, by means of which the laundry to be cleaned additionally dries after the washing process or after the spinning and / or rinsing process. It is of course advantageous if a fan is provided as a drying unit, which for example blows warm and dry air into the washing chamber. It is further advantageous if the drying device also comprises an opening element provided on the ceiling or on the cover plate of the washing chamber, such as, for example, a closable and openable flap, via which, in particular, steam can escape and / or advantageously be sucked off can.

Advantageously, the carousel or the washing rack in the washing chamber is designed such that the laundry items to be cleaned are clamped or fixed for the washing and / or spinning process.

For this purpose, according to a variant of the invention adjustable clamping elements are provided to clamp the laundry items. These adjustable clamping elements are designed so that they at least partially include the laundry or set so that it can not slip due to the rotational movement of the washing rack.

The invention is characterized according to an advantageous development, which is of course also in connection with the previously disclosed features individually or jointly applicable, characterized in that the receiving or insert elements are formed and spaced from each other or positionable so that they on the pallets for the laundry can be applied existing inner pallet feet and serve the pallet feet for centering and / or lateral fixation and / or guidance. This is of course a considerable relief such that you do not have to attach additional guidance and fixation, because you can just use the same recording or insert elements by being applied to the pallet feet. Even when inserting this results in a relief, because of course, a lateral guidance and subsequent fixation is possible.

A further development of the embodiment described above, which of course can also be used in connection with the main invention or one of the features disclosed thereafter, is characterized in that at least one closable, preferably two securing bracket are provided, the / on the washing rack or the carousel are arranged. The securing brackets are bent in such a way that, when closing, they grip the outer pallet feet of a pallet and can thereby clamp the pallet as a whole. It is of considerable advantage that the design of the securing bracket is such that you can safely grasp and fix both the wide pallets and the narrower pallets. This means that the angled part of the securing bracket is designed in such a length that several dimensions of pallets can be covered with it. In the embodiment, while an embodiment is shown, with which it is possible to take two different dimensions of pallets, the invention is of course not limited to such a configuration. Rather, it is possible by the design of the securing bracket, in accordance with a greater gradation of pallet dimensions also secure, which makes the device even more comfortable.

This object of the invention is also achieved by a system for cleaning laundry comprising at least one device according to one of the preceding claims and further comprising a first storage element, which is arranged along a conveying direction in front of the washing chamber of the device and a second storage element, which along which Transport direction is arranged behind the washing chamber of the device, wherein on the first conveyor and the second conveyor laundry items, in particular in the form of pallet stacks, can be applied and further comprising a changing device which automatically removes laundry items from the first storage element and automatically introduces for cleaning in the washing chamber, said the replacement device automatically removes the cleaned laundry from the wash chamber after the end of the cleaning process and applies it to the second storage element. An inventive system is used for the automatic cleaning of a large amount of Waschgutelementen. For this purpose, the system has at least one device for cleaning laundry according to one of the previously described embodiments. In this washing device all laundry items are cleaned. Of course, several washing devices can be provided. Adjacent to the washing device, a first and a second storage element are provided, wherein the laundry to be cleaned is applied to the first storage element and the laundry already cleaned by the washing device is applied to the second storage element. Both storage elements have movable components which move along a conveying direction. Conveniently, the conveying direction of the first storage element is directed towards the washing device, wherein the conveying direction of the second storage element is directed away from the washing device. Ideally, there is only a single conveying direction and the storage elements are arranged so that they extend along this common conveying direction. The laundry items move with the movable elements of the storage elements along the conveying direction. At a central location, adjacent to the first storage element, the second storage element and washing device or washing chamber, a changing device is arranged, which removes the laundry from the first storage element and introduces into the washing device. After performing the washing process, the changing device then removes the laundry cleaned from the washing device and applies it to the second storage element. The changing device is provided for this purpose with receiving elements which can grip the laundry items or otherwise absorb. The changing device works automatically. The changing device can be designed, for example, as a robot arm. Of course, other embodiments of the changing device are associated with the invention. The storage elements are used to have a certain supply of both soiled and cleaned laundry in the system. As already described, the system works largely automatically. However, laundry must be supplied and removed by an operator. The storage elements serve to form a kind of buffer and thereby give the operator time to bring in or remove laundry. A system according to the invention makes it possible for only one person to undertake the entire logistics for cleaning a larger number of laundry items. While the operator removes items of laundry items that are cleaned on the second storage element, the washing device is automatically supplied with dirty laundry items from the first storage element. If the operator is then finished with the removal of the cleaned laundry, he can refill soiled laundry on the first storage element, while the cleaned laundry is buffered on the second storage element. An inventive system thus allows a very high throughput of Waschgutelementen with very little staff. In a preferred embodiment it is provided that the first storage element and the second storage element are designed as a conveyor belt and the washing process in the washing chamber automatically starts after the introduction of the laundry by the changing device. Conveyor belts are suitable storage elements because they are simple and available in many different embodiments on the market. Of course, the invention is not limited to an embodiment of the storage elements as conveyor belts. For example, carousel arrangements would be alternative conceivable, which rotate around a central point and thus move the laundry items further. Ideally, the washing process in the washing device or washing chamber starts automatically as soon as the changing device has introduced a batch of laundry items into the washing chamber.

1 shows a sectional side view through an embodiment of a washing device according to the invention in the feed state. On the right side of 1 an embodiment of a device according to the invention is shown, which is in the feed state. In the loading state, the laundry, here a stack of laundry items 2 in the form of pallets in the wash chamber 1 brought in. In the wash chamber 1 is for receiving the laundry, the receiving device A is provided. The receiving device A here comprises a frame 4 which extends substantially in the vertical direction and the receiving device A positioned in the washing chamber 1 and carries. Furthermore, the receiving device A comprises the distance changing device B. The distance changing device B includes all components that are the change in the distance between the introduced Waschgutelementen 2 serve. Vertically arranged in vertical direction, the distance changing device B comprises a plurality of lifting devices C. Each lifting device C is used in the embodiment shown, each a Waschgutelement 2 take. Each lifting device C comprises at least one receiving element as a subassembly 3 , In the case shown, the receiving elements 3 designed as forks, similar to those of a forklift, which causes the Waschgutelemente 2 in the form of pallets safe and easy on the receiving elements 3 let it hang. The recording elements 3 but may also have a different shape, if this is to accommodate the laundry items 2 is required. The recording elements 3 are thus interfaces of the lifting devices C to the laundry items 2 which can be customized according to the application. The lifting devices C further each include a pressure plate 5 , At the pressure plate 5 is the receiving element 3 attached. The printing plate 5 serves furthermore to the lifting device C slidably and movably on the frame 4 to store. In the illustrated form, the pressure plate 5 to at least two rollers or rollers on which running on the vertical frame 4 unroll and allow a displacement in the vertical direction. It is of course also possible, a movable storage between pressure plate 5 and frame 4 to realize by another type of bearing, for example by a sliding bearing or the like. In the illustrated loading condition the distance between the adjacent lifting devices C is minimal, the pressure plates 5 the adjacent lifting devices C are directly adjacent to each other. The distance changing device B further comprises a traction means 40 , which is designed in the illustrated embodiment as a metal chain. A metal chain has the advantage of being permanently resistant to the moist and partly chemically aggressive environment in the wash chamber, in which at the same time regular high washing temperatures prevail. The traction device 40 is by means of a coupling element 42 attached to the lowest lifting device C. The coupling element 42 Here is a metal angle, which is under the pressure plate 5 the lowest lifting device C engages. The connection between pressure plate 5 and coupling elements 42 can be done via its positive connection. Furthermore, it is also possible coupling element 42 and to connect lifting device C cohesively, for example, to weld together. Near the upper end of the washing chamber 1 is the length changing device 41 appropriate. The length change device comprises the deflection roller 44 , The traction device 40 initially runs from the coupling element 42 vertically upwards and over the deflection roller 44 , Right next to the deflection roller 44 is the also to the length change device 41 associated linear drive 45 appropriate. One end of the traction device 40 is near the linear drive 45 fixed to the attachment 49 mounted in the wash chamber. The attachment 49 can be performed, for example, as a screw be, with the end of the traction device 40 is clamped stationary. The part of the traction device 40 that is between the attachment 49 and the pulley 44 extends is as a residual length of the traction means 40 Are defined. The part of the traction device 40 which is in the vertical direction between pulley 44 and coupling element 42 extends is considered effective length of the traction device 40 designated. In the illustrated form presses the release 46 of the linear drive 45 on the remaining length of the traction device 40 , In the illustrated loading condition is the release 46 fully extended, whereby the pressed down by the releaser residual length of the traction device 40 maximum length and thus the effective length of the traction device 40 is minimal short. The lifting devices C are characterized without spacing on each other. When retracting the release 46 reduces the residual length of the traction device 40 and there is gradually a change in the 2 illustrated state of the washing position. On the left side of the wash chamber 1 is a closable opening 10 to recognize, which is formed here by a door, not shown. In the lower part of the wash chamber 1 there is a liquid-tight floor area 101 , This floor area 101 extends in the vertical direction to the end of the height of the lintel 102 , The floor area 101 is thus formed by a tub whose upper edge of the lintel 102 is. It can be seen that the edge of the lintel 102 well above the level of the surrounding soil. This ensures that no water from the wash chamber 1 , can leak to the outside. In the prior art had the lintel 102 be made significantly lower, since the laundry items 2 only directly at ground level introduced into the device and could be attached to this. The increase of the lintel 102 thus brings a clear advantage in terms of leak safety. The laundry items 2 are stacked from the forklift 50 in the wash chamber 1 brought in. The forklift takes the stack on his fork 51 on and hangs all laundry items 2 at the same time on the lifting devices C or their receiving elements 3 one. As in 1 can be clearly seen, is the fork 51 of the forklift 50 when introducing the laundry in an elevated position relative to the floor level. As a result, the driver of the forklift has a much better view of the laundry, as if the laundry would be just above the floor level during insertion. Thus, the entire configuration of the distance changing device B, in which the lifting devices C are in the upper level when loaded, surprisingly brings significant advantages over the state of the art in introducing the laundry. In the description so far 1 only the lifting devices C, which are actually shown in the picture, became frame 4 etc. written. It is of course possible that several of these assemblies are arranged in the drawing plane in succession and each cooperate individually or in parallel with the illustrated elements. In practice, two corresponding lifting devices C will usually be provided next to each other in the horizontal direction. However, the invention is not limited to such a double embodiment of the elements.

2 shows a sectional side view through an embodiment of a washing device according to the invention in the washing position. 2 corresponds in the presentation 1 , In 2 However, the washing position is shown in the laundry items 2 already introduced into the device. The lockable opening 10 is closed and therefore not shown anymore. The lifting devices C and thus the laundry items 2 are now spaced from each other to allow detergent during the washing process all surfaces of Waschgutelemente 2 reaches and cleans. The releaser 46 of the linear drive 45 is no longer visible, because he is completely retracted. The residual amount of the traction device 40 is minimal in the illustrated case, so that the traction means 40 directly between the attachment 49 and the pulley 44 runs. The effective length of the traction device 40 on the other hand is maximum, so that is the coupling element 42 fixed end of the traction device 40 near the bottom of the wash chamber 1 located. Between the lifting devices C is in each case a spacer element 43 to recognize which adjacent lifting devices C in the printing plates 5 connects in the vertical direction. By providing a spacer element 43 between the individual lifting devices C, a vertical linking of all lifting devices C is achieved. When extending the effective length of the train by means of 40 gradually all displaceably mounted spacers 43 extended. The spacer elements 43 have an end stop, from the achievement of no further displacement of the spacer elements 43 with respect to the lifting devices C is more possible. Once this end stop has been reached, the maximum distance between the lifting devices C has been reached. The spacers 43 can be designed as a bolt or cylinder, which are fixedly attached to a lifting device C and are movably mounted to the end stop in the adjacent lifting device. When changing from the charging state to the washing position, each distance between the individual lifting devices C is gradually increased until the end stop of the spacer elements 43 is reached. The end result is in 2 shown, all lifting devices are now complained to each other. When changing back to the loading state, the effective length of the traction device 40 shortened again and the spacers 43 gradually return to the lifting devices C on until the lifting devices C all again rest on each other.

3 shows a device according to the invention in a schematic plan view. It becomes clear that, for example, a carousel 11 is provided, on which an unspecified wash rack is arranged. This carousel 11 can be - as already mentioned several times - put in a rotary motion. To now the washing rack on the carousel or the laundry items to be washed 2 set there, it is provided according to the invention that clamping elements 12 / 1 to 12 / 6 are provided, which, as indicated by the double arrow, can be moved to the laundry to or from this. With the reference number 10 is the opening of the wash chamber 1 denotes, over which the material to be washed is introduced into the chamber and from which it can then of course be removed again after the washing process.

The 4 shows a special configuration for a receiving element 3 according to the invention. The receiving element 3 is formed pike-like and that of the frame 4 opposite side. A palette 70 is here indicated only schematically and in two different sizes. For example, as a pallet in the dimensions 1000 x 1200 mm, which is represented by the outer dashed lines and by the inner cross-hatched representation in the dimensions 800 x 1200 mm. At the pallet 70 themselves are initially inner palette feet 16 provided that serve the pallet exactly centric between the two receiving or inserting elements 3 can position and fix. The recording elements 3 are, as can be seen, designed as forks or forked. The horizontal distance from each other is adjustable so that the inner pallet feet 16 for insertion and in particular for fixing in the horizontal plane can be used with. Furthermore, it can be seen that at the carousel 11 or on the washing rack of the device securing bracket 17 are provided. This safety bar 17 are angled so that when closing the outer palette feet 18 grab and thereby the pallet 70 in total. Again, it can be seen that the design of the safety bar 17 so is that you can handle both the wide pallets 70 as well as the narrower pallets 70 can safely grasp and fix. That is, the angled portion of the safety bar 17 is designed in such a length that both dimensions can be safely covered.

The circlips 17 are secured by toggle, not shown, so that an opening is excluded. In this way it is achieved that only left and right on the side facing away from the frame 4 side, the securing bracket 17 are closed and thus the pallet 70 securely fixed. This is falling out or falling, but also slipping and moving the pallet 70 , and also the laundry, here no longer possible. The pointed configuration of the forks is also advantageous because for this reason the pallets 70 in the entry shaft of the pallet 70 can be securely fixed. That is, the pallets, which were retracted eccentrically, for example, can be safely retracted by this device in the middle and there fixed or centered and that from both sides.

5 shows a sectional side view through a further embodiment of a washing device according to the invention in the feed state. In the 5 and 6 The embodiment shown is very similar to that in FIGS 1 and 2 illustrated embodiment. Therefore, unless otherwise stated, the description of these figures in the preceding paragraphs applies. The pulley 44 is in the in 5 illustrated embodiment larger sized and arranged so that the traction means 40 with its effective length now on the laundry side facing the frame 4 runs. The tension element 40 is also here with a coupling element 42 connected to the lowermost lifting device C. Starting from this point on the lowermost lifting device C the traction means runs 40 First, move vertically upwards and then over the pulley 44 guided. The effective length of the traction device 40 extends from the coupling element 42 to the pulley 44 , That the coupling element 42 opposite end of the traction device 40 is in this embodiment directly at the end of the release 46 of the linear drive 45 attached. If the laundry is to be removed, the releaser 46 extended and takes in this movement one end of the traction device 40 With. This will be the traction means 40 over the pulley 44 moved and whose effective length is shortened. The lifting devices C with the laundry are moved upward, so that finally the feed state is reached. In the 5 embodiment shown is simpler than the 1 shown embodiment. This will be in 5 a stronger linear actuator is needed because compared to 1 a lower gear ratio is present, which is due to the lack of a second attachment point of the traction means 40 is conditional. In the in 5 embodiment shown is opposite to in 1 shown embodiment, a linear drive 45 needed, its releaser 46 can travel the double way. In practice, release lengths of up to 50 cm have as unproblematic. In the in 5 illustrated embodiment, the deflection roller 44 designed so that the effective length of the traction device 40 on the laundry side facing the frame 4 extends. This relieves the traction means 40 the bearings of the lifting devices C on the frame 4 mechanically.

6 shows a sectional side view through a further embodiment of a washing device according to the invention in the washing position. 6 shows the embodiment 5 in which the releaser 46 almost completely in the linear drive 45 retracted and the device occupies the washing position, in which the laundry is isolated. The effective length of the traction device 40 is maximum in this washing position.

7 shows a plan view of an embodiment of a system according to the invention. In the middle of the illustration is from above the outline of the wash chamber 1 to see. The lockable opening 10 , which is here designed as a double door, is open, allowing laundry in the wash chamber 1 can be introduced or removed from it. In 7 are each several Waschgutelemente as a stack of pallets 22 stacked on top of each other. These pallet stacks 22 look like a single palette in the top view. It is good to see that there is a pallet stack 22 in the wash chamber 1 located. Above and below the wash chamber 1 are temporally offset to this the first memory element 25 and the second memory element 26 arranged. The memory elements are not visible themselves, however, arranged on these memory elements pallet stack 22 , The memory elements 25 . 26 are designed as conveyor belts, which the pallet stacks 22 in the conveying direction 23 move. The on the first memory element 25 arranged pallet stack 22 be along the conveying direction 23 to the wash chamber 1 moved. The already cleaned pallet stacks 22 be through the second memory element 26 along the conveying direction 23 from the wash chamber 1 moved away. The changing device 27 is arranged to be the first memory element 25 , the washing chamber 1 and the second storage element 26 can reach. After completion of a washing process, the changing device automatically opens the washing chamber 1 , removes the cleaned pallet stack 22 and places it on the second storage element 26 , Subsequently, the changing device removes a dirty pallet stack 22 from the lower end of the first memory element 25 and brings this automatically into the wash chamber 1 one. After closing the wash chamber 1 the washing process will be started automatically. At the lower end of the second storage elements 26 is a forklift 50 to see who is about to get a pallet stack 22 from the second memory element 26 refer to. In the same way, the first storage element by a forklift with dirty pallet stacks 22 be loaded. Characterized in that the two conveyor belts (first storage element 25 and second memory element 26 ) only slowly and as needed in Fördererrichtung 23 move, the two memory elements 25, 26 act as a buffer for pallet stack 22 so that the driver of the forklift 50 enough time for changing the pallet stacks 22 during which the system will continue to work automatically. Instead of the pallet stacks 22 Of course, a system according to the invention can also process other types of laundry, for example racks on which the laundry items are suspended.
