Description

Die Erfindung betrifft eine GeschirrspĆ¼lmaschine mit einer DƤmpfungsvorrichtung und ein Verfahren zum Herstellen einer DƤmpfungsvorrichtung.The invention relates to a dishwasher with a damping device and a method for producing a damping device.

Die DE 10 2005 010 616 A1 offenbart eine GeschirrspĆ¼lmaschine mit einem SpĆ¼lbehƤlter, in dem zwei Geschirrkƶrbe zur Aufnahme von zu reinigendem SpĆ¼lgut angeordnet sind. Mittels geeigneter FĆ¼hrungen und eines Antriebs kƶnnen die Geschirrkƶrbe aus dem SpĆ¼lbehƤlter herausbewegt und in den SpĆ¼lbehƤlter hinein bewegt werden. Der Antrieb kann einen Elektromotor umfassen oder als ein Kraftspeicher ausgebildet sein. Wird ein Kraftspeicher als Antrieb verwendet, dann kann die durch den Kraftspeicher eingeleitete Bewegung zumindest in der Bewegungsendphase durch ein DƤmpfungsmittel gedƤmpft werden.The DE 10 2005 010 616 A1 discloses a dishwasher with a washing container in which two baskets are arranged for receiving items to be cleaned. By means of suitable guides and a drive, the baskets can be moved out of the washing and moved into the washing in it. The drive may comprise an electric motor or be designed as a force storage. If an energy storage device is used as the drive, then the movement initiated by the energy storage device can be damped by a damping means, at least in the movement end phase.

Aufgabe der Erfindung ist es, eine verbesserte GeschirrspĆ¼lmaschine, insbesondere eine HaushaltsgeschirrspĆ¼lmaschine mit einem GeschirrbehƤlter, dem eine DƤmpfungsvorrichtung zugeordnet ist, anzugeben.The object of the invention is to provide an improved dishwasher, in particular a domestic dishwasher with a dish container, which is associated with a damping device.

Die Aufgabe der Erfindung wird gelƶst durch eine GeschirrspĆ¼lmaschine, aufweisend einen SpĆ¼lbehƤlter, wenigstens einen mittels FĆ¼hrungen aus dem SpĆ¼lbehƤlter heraus und in den SpĆ¼lbehƤlter hinein bewegbaren GeschirrbehƤlter und wenigstens eine DƤmpfungsvorrichtung zum DƤmpfen einer Bewegung des GeschirrbehƤlters, wobei die DƤmpfungsvorrichtung innerhalb des SpĆ¼lbehƤlters angeordnet ist. Die erfindungsgemƤƟe GeschirrspĆ¼lmaschine ist insbesondere eine HaushaltgeschirrspĆ¼lmaschine. Dadurch, dass die DƤmpfungsvorrichtung innerhalb des GeschirrspĆ¼lbehƤlters angeordnet ist, kann sie beispielsweise relativ einfach montiert werden. Auch bietet der SpĆ¼lbehƤlter mehr Platz als beispielsweise die beengten VerhƤltnisse z.B. hinter der RĆ¼ckwand des SpĆ¼lbehƤlters. Aufgrund der Anordnung der DƤmpfungsvorrichtung innerhalb des SpĆ¼lbehƤlters ist es auch mƶglich, dass die DƤmpfungsvorrichtung besser mit dem GeschirrbehƤlter gekoppelt werden kann, um dessen Bewegung zu dƤmpfen.The object of the invention is achieved by a dishwasher having a rinsing container, at least one by means of guides out of the rinsing out and into the rinsing container into movable crockery container and at least one damping device for damping a movement of the dishware, wherein the damping device is disposed within the rinsing container. The dishwasher according to the invention is in particular a household dishwasher. By virtue of the fact that the damping device is arranged inside the dishwashing container, it can be mounted relatively easily, for example. Also, the rinse container offers more space than, for example, the cramped conditions behind the rear wall of the rinse container, for example. Due to the arrangement of the damping device within the washing container, it is also possible that the damping device can be better coupled to the dish container to dampen its movement.

Vorzugsweise ist die DƤmpfungsvorrichtung am SpĆ¼lbehƤlter, insbesondere an einer Seitenwand des SpĆ¼lbehƤlters angeordnet bzw. befestigt.Preferably, the damping device is arranged or fastened on the washing container, in particular on a side wall of the washing container.

GemƤƟ einer Variante der erfindungsgemƤƟen GeschirrspĆ¼lmaschine weist die DƤmpfungsvorrichtung einen Kolben und ein zylinderfƶrmiges GehƤuse auf, das einen Verdichtungsraum umschlieƟt, wobei der wenigstens eine Kolben innerhalb des GehƤuses verschieblich gelagert ist und den Verdichtungsraum in TeilverdichtungsrƤume trennt. Aufgrund des im Verdichtungsraum befindlichen Fluids, das bevorzugt Luft ist, aber zumindest teilweise auch Wasser oder eine fĆ¼r die Reinigung des mittels der GeschirrspĆ¼lmaschine zu reinigenden SpĆ¼lguts vorgesehenes SpĆ¼lmittel aufweisen kann, wird beim Verschieben des Kolbens dessen Bewegung gedƤmpft, wodurch die dƤmpfende Wirkung der DƤmpfungsvorrichtung entsteht.According to a variant of the dishwasher according to the invention, the damping device has a piston and a cylindrical housing which encloses a compression space, wherein the at least one piston is displaceably mounted within the housing and separates the compression space in partial compaction spaces. Due to the fluid in the compression space, which is preferably air, but at least partially water or provided for cleaning the dishes to be cleaned by means of the dishwasher SpĆ¼lmittel provided, is dampened when moving the piston whose movement, whereby the damping effect of the damping device is formed ,

Um wƤhrend des Verschiebens des Kolbens innerhalb des GehƤuses ein Strƶmen des innerhalb des GehƤuses befindlichen Fluids von einem Teilverdichtungsraum zum anderen zu ermƶglichen, kann der Kolben vorzugsweise wenigstens eine Ɩffnung aufweisen, durch die beim Verschieben des Kolbes das innerhalb des GehƤuses befindliches Fluid von einem Teilverdichtungsraum zum anderen Teilverdichtungsraum strƶmt. Die Ɩffnung ist beispielsweise als Bohrung, insbesondere als Drosselbohrung ausgefĆ¼hrt. Sie kann auch schlitzfƶrmig ausgefĆ¼hrt sein. Es ist auch mƶglich, dass die Ɩffnung, insbesondere wenn sie schlitzfƶrmig ausgefĆ¼hrt ist, randoffen ausgefĆ¼hrt ist.In order to allow during the displacement of the piston within the housing, a flow of the fluid located within the housing from one part of the compression chamber to the other, the piston may preferably have at least one opening through which during displacement of the piston located within the housing fluid from a Teilverdichtungsraum to other partial compression space flows. The opening is designed for example as a bore, in particular as a throttle bore. It can also be slit-shaped. It is also possible that the opening, in particular if it is slit-shaped, is designed open-edged.

Das GehƤuse kann vorzugsweise die Form eines Kreiszylinders und/oder die Form eines geraden Zylinders aufweisen. Diese Formen lassen sich relativ einfach herstellen.The housing may preferably have the shape of a circular cylinder and / or the shape of a straight cylinder. These shapes are relatively easy to produce.

Um die dƤmpfende Wirkung der DƤmpfungsvorrichtung zu erhƶhen, kann wenigstens in einem der TeilverdichtungsrƤume eine Feder angeordnet sein.In order to increase the damping effect of the damping device, a spring may be arranged at least in one of the partial compression chambers.

Der Kolben kann vorzugsweise formschlĆ¼ssig innerhalb des GehƤuses verschieblich angeordnet sein. Dadurch erhƶht sich ebenfalls die DƤmpfungswirkung der DƤmpfungsvorrichtung.The piston can preferably be arranged in a form-fitting manner displaceable within the housing. This also increases the damping effect of the damping device.

Die DƤmpfungsvorrichtung der erfindungsgemƤƟen GeschirrspĆ¼lmaschine ist nach einer Variante mit ihrem GehƤuse an dem SpĆ¼lbehƤlter, insbesondere an einer Seitenwand des SpĆ¼lbehƤlters befestigt. Um eine Befestigung zu erleichtern, kann eine an dem GehƤuse angeformte Befestigungsvorrichtung vorgesehen sein, mittels derer die DƤmpfungsvorrichtung am SpĆ¼lbehƤlter befestigt ist. Die Befestigungsvorrichtung ist z.B. als eine Lasche ausgefĆ¼hrt.The damping device of the dishwasher according to the invention is according to a variant with its housing on the washing compartment, in particular on a side wall of the Rinsing container attached. In order to facilitate an attachment, a fastening device formed on the housing can be provided, by means of which the damping device is fastened to the rinsing container. The fastening device is designed for example as a tab.

Die DƤmpfungsvorrichtung kann vorzugsweise eine Kolbenstange aufweisen, an dem der wenigstens eine Kolben angeordnet ist, wobei der wenigstens eine Kolben innerhalb des GehƤuses mittels der Kolbenstange verschieblich gelagert ist. Die Kolbenstange kann z.B. mit dem GeschirrbehƤlter gekoppelt sein, um dessen Bewegung zu dƤmpfen.The damping device may preferably have a piston rod, on which the at least one piston is arranged, wherein the at least one piston is displaceably mounted within the housing by means of the piston rod. The piston rod may e.g. be coupled with the dish container to dampen its movement.

Nach einer bevorzugten AusfĆ¼hrungsform der erfindungsgemƤƟen GeschirrspĆ¼lmaschine ist das GehƤuse der DƤmpfungsvorrichtung an seinen Stirnseiten mit jeweils einer Ɩffnung versehen, durch die die Kolbenstange ragt. Somit ist es mƶglich, dass z.B. lediglich durch DrĆ¼cken auf die Kolbenstange der Kolben in zwei entgegengesetzte Richtungen innerhalb des GehƤuses verschoben werden kann. Dadurch kann z.B. eine Bewegung des GeschirrbehƤlters in beide Richtungen gedƤmpft werden.According to a preferred embodiment of the dishwasher according to the invention, the housing of the damping device is provided at its end faces, each with an opening through which the piston rod protrudes. Thus, it is possible that e.g. merely by pushing on the piston rod, the piston can be displaced in two opposite directions within the housing. Thereby, e.g. a movement of the utensil container are damped in both directions.

GemƤƟ einer bevorzugten Variante der erfindungsgemƤƟen GeschirrspĆ¼lmaschine weist diese zwei am GeschirrbehƤlter und/oder and dessen FĆ¼hrungen angeordnete AnschlƤge auf, zwischen denen die DƤmpfungsvorrichtung derart am SpĆ¼lbehƤlter angeordnet ist, dass diese mit der Kolbenstange derart zusammenwirken, dass beim Herausbewegen des GeschirrbehƤlters aus dem SpĆ¼lbehƤlter eine der Begrenzungen die Kolbenstange in eine erste Richtung und beim Hineinbewegen des GeschirrbehƤlters in den SpĆ¼lraum in einer zur ersten Richtung entgegengesetzten Richtung schiebt.According to a preferred variant of the dishwasher according to the invention, these two arranged on the dish container and / or its guides stops, between which the damping device is arranged on the washing so that they cooperate with the piston rod such that when moving out of the dish container from the washing one of Limits pushes the piston rod in a first direction and while moving the dish container into the washing compartment in a direction opposite to the first direction direction.

Somit wird jedes Mal beim Herausbewegen, z.B. beim manuellen Herausziehen des GeschirrbehƤlters aus dem SpĆ¼lbehƤlter der Kolben mittels des relevanten Anschlags und der Kolbenstange automatisch derart innerhalb des GehƤuses verschoben, so dass beim Hineinbewegen, insbesondere beim manuellen Hineinschieben des GeschirrbehƤlters in den SpĆ¼lbehƤlter die Kolbenstange gegen den relevanten Anschlag stĆ¶ĆŸt und dadurch den Kolben innerhalb des GehƤuses verschiebt. Dadurch kann die DƤmpfungsvorrichtung ihre dƤmpfende Wirkung bei jedem Hineinbewegen des GeschirrbehƤlters entfalten und insbesondere die Bewegung des GeschirrbehƤlters bei jedem Hineinbewegen von Neuem dƤmpfen.Thus, each time when moving out, for example when manually pulling out of the washing container from the rinsing the piston automatically shifted within the housing by means of the relevant stop and the piston rod, so that when moving in, especially when manually pushing the dish container into the washing the piston rod against the relevant stop abuts and thereby shifts the piston within the housing. As a result, the damping device can develop its damping effect each time the dish container is moved in, and in particular dampens the movement of the dish container each time it is moved in anew.

Um die Gefahr einer Korrosion der DƤmpfungsvorrichtung zumindest vorzubeugen, ist diese nach einer vorteilhaften AusfĆ¼hrungsvariante zumindest teilweise, vorzugsweise komplett aus Kunststoff gefertigt. Insbesondere sind das GehƤuse, der Kolben und gegebenenfalls die Kolbenstange aus Kunststoff gefertigt.In order at least to prevent the risk of corrosion of the damping device, this is according to an advantageous embodiment, at least partially, preferably made entirely of plastic. In particular, the housing, the piston and optionally the piston rod are made of plastic.

FĆ¼r eine relativ leichte Montage der DƤmpfungsvorrichtung kann nach einer zweckmƤƟigen Variante der erfindungsgemƤƟen GeschirrspĆ¼lmaschine das GehƤuse zwei TeilgehƤuse aufweisen, die insbesondere jeweils die Form eines Halbzylinders aufweisen.For a relatively easy mounting of the damping device, according to an expedient variant of the dishwasher according to the invention, the housing may have two sub-housings which in particular each have the shape of a half-cylinder.

Somit stellt ein Aspekt der Erfindung ein vorteilhaftes Verfahren zum Herstellen einer DƤmpfungsvorrichtung fĆ¼r die erfindungsgemƤƟe GeschirrspĆ¼lmaschine bereit, gemƤƟ dem die Kolbenstange in eine der beiden halbzylinderfƶrmigen TeilgehƤuse gelegt wird, sodass der Kolben in diesem TeilgehƤuse angeordnet ist. AnschlieƟend werden die beiden TeilgehƤuse verbunden, sodass das GehƤuse entsteht.Thus, one aspect of the invention provides an advantageous method for producing a damping device for the dishwasher according to the invention, according to which the piston rod is placed in one of the two semi-cylindrical part housings, so that the piston is arranged in this part housing. Subsequently, the two sub-housings are connected so that the housing is created.

Die beiden TeilgehƤuse sind vorzugsweise miteinander verklebt und/oder verrastet. Dadurch lƤsst sich die Verbindung der beiden TeilgehƤuse in relativ einfacher Weise realisieren.The two sub-housings are preferably glued together and / or locked. As a result, the connection of the two sub-housings can be realized in a relatively simple manner.

Die Erfindung stellt demnach in vorteilhafter Weise insbesondere einen EndlagendƤmpfer fĆ¼r GeschirrbehƤlter, die z.B. als Geschirrkƶrbe ausgefĆ¼hrt sind, bereit. Die DƤmpfungsvorrichtung kann insbesondere ein DƤmpfergehƤuse umfassen, das sich aus zwei HƤlften zusammensetzen kann, die insbesondere an beiden Enden eine Passbohrung ausbilden, durch die beidseitig eine Kolbenstange bewegbar ist. In der Mitte der Kolbenstange kƶnnen sich vorzugsweise eine oder mehrere Stauscheiben, allgemein Kolben z.B. mit einer Drosselbohrung befinden, die vorzugsweise formschlĆ¼ssig in den Verdichtungsraum des DƤmpfergehƤuses eingesetzt ist. Die Kolbenstange wird z.B. mittels einer Platte an der KorbfĆ¼hrung oder am Geschirrkorb in eine Richtung verschoben. Die einseitig im Verdichtungsraum befindliche Luft strƶmt gegebenenfalls durch die Drosselbohrung der Stauscheibe in den gegenĆ¼berliegenden Stauraum des DƤmpfergehƤuses. Die dadurch entstehende DƤmpferwirkung kann ggf. durch zusƤtzlich in den Stauraum eingebrachte Federn verstƤrkt werden. Das DƤmpfergehƤuse wird gegebenenfalls nach dem Einlegen der Kolbenstange z.B. durch Kleben und/oder Rasten verschlossen und beispielsweise durch eine angespritzte Lasche am BehƤlter befestigt.The invention accordingly advantageously provides, in particular, an end stop damper for dishware containers, which are designed, for example, as dish racks. The damping device may in particular comprise a damper housing, which may be composed of two halves, which in particular form a fitting bore at both ends, by means of which a piston rod can be moved on both sides. In the middle of the piston rod may preferably be one or more baffle plates, generally piston, for example with a throttle bore, which is preferably inserted positively into the compression space of the damper housing. The piston rod is moved, for example by means of a plate on the basket guide or on the dish rack in one direction. The air located on one side in the compression chamber optionally flows through the throttle bore of the baffle plate in the opposite storage space of the damper housing. The resulting damper effect can possibly be reinforced by additionally introduced into the storage space springs. The damper housing is optionally closed after insertion of the piston rod, for example by gluing and / or locking and fixed for example by a molded tab on the container.

Ein Vorteil der erfindungsgemƤƟen GeschirrspĆ¼lmaschine kann insbesondere sein, dass z.B. kein ruckartiger Stopp des GeschirrbehƤlters am Endanschlag der GeschirrbehƤlterfĆ¼hrung entsteht. Eine Gefahr eines Herumfallen von Geschirrteile kann somit zumindest verhindert, wenn nicht gar vermieden werden. Eine Haptik fĆ¼r eine Bedienperson der erfindungsgemƤƟen GeschirrspĆ¼lmaschine kann ebenfalls verbessert werden.An advantage of the dishwasher according to the invention may be in particular that e.g. no jerky stop of the dish container at the end stop of the dish container guide is formed. A risk of falling over pieces of crockery can thus at least prevented, if not avoided. A feel for an operator of the dishwasher according to the invention can also be improved.

Sonstige Weiterbildungen der Erfindung sind in den abhƤngigen AnsprĆ¼chen wiedergegeben. Die Erfindung und ihre Weiterbildung sowie deren Vorteile werden nachfolgend anhand von Zeichnungen erlƤutert. Es zeigen jeweils schematisch:

Elemente mit gleicher Funktion und Wirkungsweise sind in den Figuren 1 bis 3 jeweils mit denselben Bezugszeichen versehen.Elements with the same function and mode of action are in the FIGS. 1 to 3 each provided with the same reference numerals.

Die Fig. 1 zeigt in geschnittener Darstellung eine HaushaltsgeschirrspĆ¼lmaschine 1 als Beispiel einer GeschirrspĆ¼lmaschine.The Fig. 1 shows a sectional view of a household dishwasher 1 as an example of a dishwasher.

Die HaushaltsgeschirrspĆ¼lmaschine 1 weist einen SpĆ¼lbehƤlter 2 zur Aufnahme von SpĆ¼lgut auf, das beispielsweise in Ć¼bereinander angeordnete, als Geschirrkƶrbe 3 ausgebildete GeschirrbehƤlter eingeordnet werden kann. Der SpĆ¼lbehƤlter 2 weist zwei SeitenwƤnde 4a und eine RĆ¼ckwand 4 auf und kann mittels einer nicht nƤher gezeigten, bezĆ¼glich einer horizontalen Achse verschwenkbaren TĆ¼r verschlossen werden, wie dies Ć¼blich ist. Bei geƶffneter TĆ¼r kƶnnen die beiden Geschirrkƶrbe 3 mittels FĆ¼hrungen 3a aus dem SpĆ¼lbehƤlter 2 gezogen werden, um ein Be- und Entladen der Geschirrkƶrbe 3 zumindest zu erleichtern. Mittels der FĆ¼hrungen 3a kƶnnen die Geschirrkƶrbe 3 auch in den SpĆ¼lbehƤlter 2 eingeschoben werden.The domestic dishwasher 1 has a washing container 2 for receiving items to be washed, which can be arranged, for example, in one above the other, designed as baskets 3 dish container. The washing container 2 has two side walls 4a and a rear wall 4 and can be closed by means of a not shown in detail, with respect to a horizontal axis pivotable door, as is usual. When the door is open, the two baskets 3 by means of guides 3a the rinsing 2 are pulled to facilitate loading and unloading of the baskets 3, at least. By means of the guides 3a, the crockery baskets 3 can also be inserted into the washing container 2.

In dem SpĆ¼lbehƤlter 2 sind beispielsweise zumindest zwei SprĆ¼hvorrichtungen zum Beaufschlagen des SpĆ¼lguts mit einer FlĆ¼ssigkeit angeordnet, die Ć¼blicherweise als SpĆ¼lflotte bezeichnet wird. Im Falle des vorliegenden AusfĆ¼hrungsbeispiels sind die SprĆ¼hvorrichtungen als obere und untere SprĆ¼harme 5, 6 ausgebildet. Die FlĆ¼ssigkeit kann von einer UmwƤlzpumpe 7 Ć¼ber eine erste FlĆ¼ssigkeitszuleitung 8 zum oberen SprĆ¼harm 5 und Ć¼ber eine zweite FlĆ¼ssigkeitszuleitung 9 zum unteren SprĆ¼harm 6 gefƶrdert werden. Die UmwƤlzpumpe 7 wird z.B. mittels eines nicht nƤher dargestellten elektrischen Antriebs, insbesondere mittels dessen elektrischen Motors, angetrieben.In the washing container 2, for example, at least two spraying devices for applying the washware are arranged with a liquid, which is usually referred to as rinsing liquor. In the case of the present embodiment, the spraying devices are designed as upper and lower spray arms 5, 6. The liquid can be conveyed by a circulation pump 7 via a first liquid supply line 8 to the upper spray arm 5 and via a second liquid supply line 9 to the lower spray arm 6. The circulation pump 7 is e.g. by means of an electric drive, not shown, in particular by means of its electric motor driven.

Im Falle des vorliegenden AusfĆ¼hrungsbeispiels wird die FlĆ¼ssigkeit zumindest in einem Teilprogrammschritt eines SpĆ¼lprogramms der HaushaltsgeschirrspĆ¼lmaschine 1 durch einen Durchlauferhitzer 10 erwƤrmt, der mit einem Eingangsstutzen 11 an die UmwƤlzpumpe 7 und mit Ausgangsstutzen 12, 13 an die FlĆ¼ssigkeitszuleitungen 8, 9 angeschlossen ist. Die Anzahl der Ausgangsstutzen 12, 13 entspricht der Anzahl der SprĆ¼harme 5, 6 oder gleichzeitig betriebener Gruppen von SprĆ¼harmen 5, 6. Die von der UmwƤlzpumpe 7 gefƶrderte FlĆ¼ssigkeit wird demnach im Falle des vorliegenden AusfĆ¼hrungsbeispiels zum Eingangsstutzen 11 des Durchlauferhitzers 10 und von dessen Ausgangsstutzen 12, 13 Ć¼ber die FlĆ¼ssigkeitszuleitungen 8, 9 zu den SprĆ¼harmen 5, 6 geleitet.In the case of the present embodiment, the liquid is heated, at least in a partial program step of a washing program of the domestic dishwasher 1 by a water heater 10 which is connected to an inlet nozzle 11 to the circulation pump 7 and with outlet nozzle 12, 13 to the liquid supply lines 8, 9. The number of outlet ports 12, 13 corresponds to the number of spray arms 5, 6 or simultaneously operated groups of spray arms 5, 6. The funded by the circulation pump 7 liquid is therefore in the case of the present embodiment to the inlet nozzle 11 of the water heater 10 and the output port 12th , 13 via the liquid supply lines 8, 9 to the spray arms 5, 6 passed.

Die HaushaltsgeschirrspĆ¼lmaschine 1 weist ferner eine Wasserweiche 14 auf, die z.B. im Durchlauferhitzer 10 angeordnet oder an diesem angeformt ist. Die Wasserweiche 14 kann z.B. aber auch in der HaushaltsgeschirrspĆ¼lmaschine 1 fĆ¼r sich allein angeordnet oder unmittelbar an die UmwƤlzpumpe 7 angeschlossen sein.The domestic dishwasher 1 further comprises a water diverter 14, e.g. arranged in the flow heater 10 or is integrally formed thereon. The water diverter 14 may e.g. but also be arranged in the household dishwasher 1 by itself or be connected directly to the circulation pump 7.

Mittels der Wasserweiche 14 kƶnnen die SprĆ¼harme 5, 6 jeweils abwechselnd und/oder stƤndig mit der FlĆ¼ssigkeit beschickt werden, was durch Ɩffnen eines FlĆ¼ssigkeitsauslasses und durch VerschlieƟen eines anderen FlĆ¼ssigkeitsauslasses der Wasserweiche 14 erzielt wird.By means of the water switch 14, the spray arms 5, 6 can be alternately and / or constantly charged with the liquid, which is achieved by opening a liquid outlet and by closing another liquid outlet of the water switch 14.

Um beim Hineinschieben der Geschirrkƶrbe 3 in den SpĆ¼lbehƤlter 2 einen Aufprall der Geschirrkƶrbe 3 auf die RĆ¼ckwand 4 des SpĆ¼lbehƤlters 2 zu dƤmpfen, sind die Geschirrkƶrbe 3 jeweils mit einer in den Figuren 2 und 3 gezeigten DƤmpfungsvorrichtung 15 versehen. Die Fig. 2 zeigt die DƤmpfungsvorrichtung 15 in einer perspektivischen Darstellung und die Fig. 3 zeigt Bestandteile der DƤmpfungsvorrichtung 15.In order to dampen an impact of the baskets 3 on the rear wall 4 of the washing container 2 when inserting the baskets 3 in the washing container 2, the baskets are 3 each with a in the FIGS. 2 and 3 shown damping device 15 is provided. The Fig. 2 shows the damping device 15 in a perspective view and the Fig. 3 shows components of the damping device 15th

Im Falle des vorliegenden AusfĆ¼hrungsbeispiels weist die DƤmpfungsvorrichtung 15 ein hohlzylinderfƶrmiges DƤmpfergehƤuse 16 auf. Das DƤmpfergehƤuse 16 hat insbesondere die Form eines geraden Zylinders und hat vorzugsweise die Form eines Kreiszylinders. Die beiden Stirnseiten des DƤmpfergehƤuses 16 sind durch Wandungen 17 begrenzt, die jeweils mit einer Ɩffnung 18, die insbesondere als Passbohrung ausgefĆ¼hrt ist, versehen. Somit schlieƟt das DƤmpfergehƤuse 16 einen Verdichtungsraum 19 ein. Das DƤmpfergehƤuse 16 ist z.B. aus Kunststoff oder aus Metall.In the case of the present embodiment, the damping device 15 has a hollow-cylindrical damper housing 16. The damper housing 16 has in particular the shape of a straight cylinder and preferably has the shape of a circular cylinder. The two end faces of the damper housing 16 are bounded by walls 17, each provided with an opening 18, which is designed in particular as a fitting bore. Thus, the damper housing 16 includes a compression space 19. The damper housing 16 is e.g. made of plastic or metal.

Die DƤmpfungsvorrichtung 15 weist im Falle des vorliegenden AusfĆ¼hrungsbeispiels eine Kolbenstange 20 auf, die durch die Ɩffnungen 18 der Wandungen 17 des DƤmpfergehƤuses 16 hindurchgefĆ¼hrt ist und somit beidseitig aus dem DƤmpfergehƤuse 16 ragt. Die GrĆ¶ĆŸe der Ɩffnungen 18 ist an die Ausdehnung der Kolbenstange 20 angepasst. Somit kann die Kolbenstange 20 lƤngs der LƤngsachse 21 des DƤmpfergehƤuses 16 in Richtung von Pfeilen 22, 23 verschoben werden. Die Kolbenstange 20 ist z.B. aus Kunststoff.The damping device 15 has in the case of the present embodiment, a piston rod 20 which is passed through the openings 18 of the walls 17 of the damper housing 16 and thus projects from both sides of the damper housing 16. The size of the openings 18 is adapted to the extent of the piston rod 20. Thus, the piston rod 20 along the longitudinal axis 21 of the damper housing 16 in the direction of arrows 22, 23 are moved. The piston rod 20 is e.g. made of plastic.

Im Falle des vorliegenden AusfĆ¼hrungsbeispiels umfasst die DƤmpfungsvorrichtung 15 wenigstens einen Kolben, der z.B. als Stauscheibe oder Platte 24 ausgefĆ¼hrt ist, die an der Kolbenstange 20 befestigt, insbesondere an dieser einstĆ¼ckig, bevorzugt einstofffig angeformt ist. Die Platte 24 ist derart ausgefĆ¼hrt, dass sie den Verdichtungsraum 19 in zwei TeilverdichtungsrƤume teilt, deren GrĆ¶ĆŸe von der Position der Kolbenstange 20 und somit von der Position der Platte 24 relativ zum DƤmpfergehƤuse 16 abhƤngt. Die Platte 24 ist formschlĆ¼ssig im Verdichtungsraum 19 eingesetzt. Damit bei einer axialen Bewegung der Kolbenstange 20 und somit der Platte 24, d.h. bei einer longitudinalen Bewegung der Kolbenstange 20 bzw. der Platte 24 Luft oder eine Fluid, z.B. Wasser von dem einen Teilverdichtungsraum zum anderen gelangen kann, ist die Platte 24 mit wenigstens einer Ɩffnung 25 bzw. mit wenigstens einer Drosselbohrung versehen. Die Ɩffnung 25 kann rund oder auch schlitzfƶrmig ausgebildet sein oder auch randoffen sein.In the case of the present embodiment, the damping device 15 comprises at least one piston, which is designed for example as a baffle plate or plate 24 which is attached to the piston rod 20, in particular integrally formed on this, preferably einstofffig. The plate 24 is designed such that it divides the compression space 19 into two partial compression chambers whose size depends on the position of the piston rod 20 and thus on the position of the plate 24 relative to the damper housing 16. The plate 24 is positively inserted in the compression chamber 19. In order for air or a fluid, eg water, to pass from one partial compression chamber to the other during an axial movement of the piston rod 20 and thus of the plate 24, ie during a longitudinal movement of the piston rod 20 or the plate 24, the plate 24 is at least one Opening 25 or provided with at least one throttle bore. The opening 25 may be round or slot-shaped or open to the edge.

Um die DƤmpfungsvorrichtung 15 zu montieren, kann, wie dies im vorliegenden AusfĆ¼hrungsbeispiel vorgesehen ist, das DƤmpfergehƤuse 16 zweiteilig aufgebaut sein und zwei halbzylinderfƶrmige TeilgehƤuse 16a, 16b umfassen. FĆ¼r die Montage wird die Kolbenstange 20 mit daran befestigter Platte 24 in eines der beiden TeilgehƤuse 16a, 16b gelegt und anschlieƟend werden die beiden TeilgehƤuse 16a, 16b miteinander verbunden, z.B. durch Verkleben oder durch Verrasten.In order to mount the damping device 15, as is provided in the present embodiment, the damper housing 16 may be constructed in two parts and comprise two semi-cylindrical part housing 16a, 16b. For assembly, the piston rod 20 with attached plate 24 is placed in one of the two sub-housings 16a, 16b and then the two sub-housings 16a, 16b are connected together, e.g. by gluing or by latching.

Im Falle des vorliegenden AusfĆ¼hrungsbeispiels ist die DƤmpfungsvorrichtung 15 mit ihrem DƤmpfergehƤuse 16 an einer der SeitenwƤnde 4a des SpĆ¼lbehƤlters 2 befestigt, z.B. mittels einer Lasche 26, die z.B. am DƤmpfergehƤuse 16 angespritzt ist. Die DƤmpfungsvorrichtung 15 ist insbesondere derart am SpĆ¼lbehƤlter 2 befestigt, sodass die LƤngsachse 21 des DƤmpfergehƤuses 16 horizontal ausgerichtet ist, d.h. parallel zur Einschieberichtung des jeweiligen Geschirrkorbs bzw. allgemein ausgedrĆ¼ckt GeschirrbehƤlters und damit parallel in Tiefenrichtung des SpĆ¼lbehƤlters verlƤuft.In the case of the present embodiment, the damping device 15 is fixed with its damper housing 16 on one of the side walls 4a of the washing container 2, e.g. by means of a tab 26, e.g. molded on the damper housing 16. The damping device 15 is in particular attached to the washing container 2 such that the longitudinal axis 21 of the damper housing 16 is aligned horizontally, i. parallel to the insertion direction of the respective dish rack or generally expressed dishware and thus runs parallel in the depth direction of the washing.

Wird nun z.B. der relevante Geschirrkorb 3, dem die DƤmpfungsvorrichtung 15 zugeordnet ist, aus dem SpĆ¼lraum 2 gezogen, dann stĆ¶ĆŸt z.B. eines der Enden 20a der Kolbenstange 20 an einem ersten Anschlag an, der z.B. als eine ersten Platte 27 ausgebildete ist, die z.B. am relevanten Geschirrkorb 3 oder an dessen FĆ¼hrung 3a befestigt ist. Dadurch wird die Kolbenstange 20 relativ zum DƤmpfergehƤuse 16 in Richtung des Pfeils 23 verschoben.Now, if e.g. the relevant crockery basket 3, to which the damping device 15 is assigned, has been pulled out of the washing compartment 2, then it is e.g. one of the ends 20a of the piston rod 20 at a first stop, e.g. is formed as a first plate 27, e.g. is attached to the relevant crockery basket 3 or to the guide 3a. As a result, the piston rod 20 is displaced relative to the damper housing 16 in the direction of the arrow 23.

Wird der jeweilige bzw. relevante Geschirrkorb 3 in den SpĆ¼lbehƤlter 2 hineingeschoben, dann stĆ¶ĆŸt das andere Ende 20b z.B. an einen zweiten Anschlag an, der beispielsweise als eine zweite Platte 28 ausgebildet ist, die z.B. am relevanten Geschirrkorb 3 oder an dessen FĆ¼hrung 3a befestigt ist. Dadurch wird die Kolbenstange 20 und somit die Platte 24 in Richtung des Pfeils 22 relativ zum DƤmpfergehƤuse 16 verschoben. Aufgrund des Verschiebens der Platte 24 gelangt durch die Ɩffnung 25 der Platte 24 Luft oder gegebenenfalls Wasser von einem der TeilverdichtungsrƤume zum anderen, wodurch eine dƤmpfende Wirkung der DƤmpfungsvorrichtung 15 entsteht. Dadurch wird beim Kontakt des Endes 20b der Kolbenstange 20 mit der zweiten Platte 28 die Bewegung des Geschirrkorbes 3 beim Hineinschieben in den SpĆ¼lraum 2 abgebremst.If the respective or relevant crockery basket 3 is pushed into the washing container 2, then the other end 20b abuts, for example, a second stop, which is designed, for example, as a second plate 28 which is fastened, for example, to the relevant crockery basket 3 or to its guide 3a , As a result, the piston rod 20 and thus the plate 24 is displaced in the direction of the arrow 22 relative to the damper housing 16. Due to the displacement of the plate 24 passes through the opening 25 of the plate 24 air or possibly water from one of the partial compression chambers to the other, whereby a damping effect of the damping device 15 is formed. As a result, when the end 20b of the piston rod 20 comes into contact with the second plate 28, the movement of the crockery basket 3 when it is pushed into the washing compartment 2 is slowed down.

Die dƤmpfende Wirkung der DƤmpfungsvorrichtung 15 kann noch verstƤrkt werden, wenn wenigstens einer der beiden TeilverdichtungsrƤume mit einer nicht nƤher dargestellten Feder versehen ist. So ist es z.B. mƶglich, in dem Teilverdichtungsraum, der durch die Platte 24 der Kolbenstange 20 und der Wandung 17, die der RĆ¼ckwand 4 des SpĆ¼lbehƤlters 2 abgewandt ist, eine Druckfeder vorzusehen.The damping effect of the damping device 15 can be further enhanced if at least one of the two partial compression chambers is provided with a spring, not shown. For example, it is possible to provide a compression spring in the partial compression space which faces away from the rear wall 4 of the washing compartment 2 through the plate 24 of the piston rod 20 and the wall 17.
