Description

Die Erfindung betrifft einen Geschirrspüler mit verstellbarem Geschirrkorb gemäss Oberbegriff von Anspruch 1.The invention relates to a dishwasher with adjustable dish rack according to the preamble of claim 1.

Ein derartiger Geschirrspüler ist in EP 372 342 beschrieben. Er besitzt einen Geschirrkorb, der in einer horizontalen und zwei gekippten Stellungen angeordnet werden kann, um den zur Verfügung stehenden Platz den jeweiligen Anforderungen anzupassen. Damit die Wasserversorgung zum Sprüharm gewährleistet ist, ist eine Kopplungsvorrichtung vorgesehen, welche mechanisch recht aufwendig ist und die Einstellmöglichkeiten des Geschirrkorbs limitiert.Such a dishwasher is in EP 372,342 described. It has a dish rack, which can be arranged in a horizontal and two tilted positions to adapt the available space to the respective requirements. Thus, the water supply to the spray arm is ensured, a coupling device is provided, which is mechanically quite expensive and limits the settings of the dish rack.

Ein ähnlicher Geschirrspüler ist ebenfalls aus der DE-A-199 26 962 bekannt.A similar dishwasher is also from the DE-A-199 26 962 known.

Es stellt sich deshalb die Aufgabe, einen Geschirrspüler der eingangs genannten Art bereitzustellen, welcher konstruktiv einfach ist und dennoch verschiedene gekippte und horizontale Stellungen des Geschirrkorbs zulässt.It is therefore the object to provide a dishwasher of the type mentioned, which is structurally simple and yet allows various tilted and horizontal positions of the dish rack.

Diese Aufgabe wird vom Geschirrspüler gemäss Anspruch 1 erfüllt.This object is achieved by the dishwasher according to claim 1.

Erfindungsgemäss ist also ein schwenkbarer Koppelkopf vorgesehen, in welchem mindestens drei Öffnungen für die Wasserzufuhrleitung vorgesehen sind. Dank der Schwenkbarkeit des Koppelkopfs kann der Geschirrkorb in zwei unterschiedlichen gekippten Stellungen und zwei unterschiedlichen Horizontalstellungen, d.h. in insgesamt mindestens vier Stellungen, mit der Wasserzufuhrleitung verbunden werden. In den gekippten Stellungen kommuniziert die Zufuhrleitung mit der mittleren Öffnung, in den Horizontalstellungen mit einer oberen bzw. einer unteren Öffnung.According to the invention therefore a pivotable coupling head is provided, in which at least three openings are provided for the water supply line. Thanks to the pivotability of the coupling head, the crockery basket can be moved in two different tilted positions and two different horizontal positions, i. in at least four positions to be connected to the water supply line. In the tilted positions, the supply line communicates with the central opening, in the horizontal positions with an upper or a lower opening.

Der Geschirrspüler ist vorzugsweise beidseitig mit höhenverstellbaren Halterungen ausgerüstet, von denen jede auf zwei unterschiedlichen Höhenstufen mit dem Geschirrkorb verbunden werden kann. Die Höhenstufen der beiden Halterungen sollten etwa auf gleicher Höhe liegen, so dass die beiden gekippten Stellungen des Geschirrkorbs etwa symmetrisch zueinander sind.The dishwasher is preferably equipped on both sides with height-adjustable brackets, each of which can be connected to the crockery basket at two different height levels. The height levels of the two brackets should be around are the same height, so that the two tilted positions of the dish rack are approximately symmetrical to each other.

In Fig. 1 ist der Bottich 1 eines Geschirrspülers dargestellt. Im Bottich sind zwei Geschirrkörbe 2, 3 angeordnet. Im folgenden wird der obere Geschirrkorb 2 im Detail beschrieben und generell als "der" Geschirrkorb bezeichnet. Der untere Geschirrkorb 3 (in Fig. 1 nur schematisch angedeutet) ist in konventioneller Weise aufgebaut.In Fig. 1 the tub 1 of a dishwasher is shown. In the tub two baskets 2, 3 are arranged. In the following, the upper crockery basket 2 will be described in detail and generally referred to as "the" crockery basket. The lower rack 3 (in Fig. 1 only schematically indicated) is constructed in a conventional manner.

Der Geschirrkorb 2 ist in zwei seitlichen Halterungen 4 angeordnet, die mit Rollen 5 in Schienen 6 geführt sind. Die Schienen 6 sind an den Seitenwänden des Bottichs 1 befestigt.The crockery basket 2 is arranged in two lateral holders 4, which are guided with rollers 5 in rails 6. The rails 6 are fixed to the side walls of the tub 1.

Der Geschirrkorb kann nach vorne ausgefahren werden, wobei die Rollen 5 in bekannter Weise in den Schienen 6 fahren und die Schienen 6 teleksopartig ausgezogen werden.The crockery basket can be extended to the front, the rollers 5 drive in a known manner in the rails 6 and the rails 6 are pulled out teleksopartig.

Jede der seitlichen Halterungen 4 besteht aus einem flexiblen Arm aus Kunststoff, in welchen der Geschirrkorb auf zwei unterschiedlichen Höhenstufen eingerastet werden kann. Fig. 2 zeigt den Geschirrkorb, wenn er in den beiden unteren Höhenstufen angeordnet ist. In Fig. 3 ist er in den beiden oberen Höhenstufen angeordnet. Somit kann der Geschirrkorb 2 zwei unterschiedliche Horizontalstellungen einnehmen.Each of the lateral supports 4 consists of a flexible arm made of plastic, in which the crockery basket can be locked at two different height levels. Fig. 2 shows the crockery basket, if it is arranged in the two lower height levels. In Fig. 3 he is located in the two upper levels. Thus, the dish rack 2 occupy two different horizontal positions.

In Fig. 4 und 5 ist der Geschirrkorb jeweils in einer Halterung 4 in der oberen Höhenstufe eingerastet und in der gegenüberliegenden Halterung 4 in der unteren Höhenstufe. Somit kann der Geschirrkorb 2 zwei unterschiedliche gekippte Stellungen einnehmen, welche um eine Kippachse parallel zur Ausfahrrichtung des Geschirrkorbs gekippt sind.In 4 and 5 the dish rack is locked in each case in a holder 4 in the upper height level and in the opposite bracket 4 in the lower height level. Thus, the dish rack 2 occupy two different tilted positions, which are tilted about a tilt axis parallel to the extension direction of the dish rack.

Da die Halterungen 4 symmetrisch zueinander ausgestaltet sind, sind auch die beiden gekippten Stellungen zueinander symmetrisch.Since the brackets 4 are designed symmetrically to each other, the two tilted positions are symmetrical to each other.

Am Geschirrkorb ist mindestens ein Sprüharm 7 angeordnet, der mit Wasser versorgt werden muss. Hierzu ist der Geschirrkorb mit einer Kopplungsvorrichtung ausgestattet, die es erlaubt, den Sprüharm mit einer Wasserzufuhrleitung zu verbinden, die an der Rückwand des Bottichs mündet.At the crockery basket at least one spray arm 7 is arranged, which must be supplied with water. For this purpose, the dish rack is equipped with a coupling device that allows to connect the spray arm with a water supply line, which opens at the rear wall of the tub.

Die Kopplungsvorrichtung umfasst einen Koppelkopf 8, der an die Zufuhrleitung angekoppelt wird. Der Koppelkopf ist mit einer im wesentlichen starren Verbindungsleitung 9 verbunden, die im Boden des Geschirrkorbs 2 etwa parallel zu dessen Ausfahrrichtung verläuft. Die Verbindungsleitung 9 führt zum Sprüharm 7, der sich ungefähr in der Mitte des Geschirrkorbs 2 befindet.The coupling device comprises a coupling head 8, which is coupled to the supply line. The coupling head is connected to a substantially rigid connecting line 9, which runs in the bottom of the dish rack 2 approximately parallel to its extension direction. The connecting line 9 leads to the spray arm 7, which is located approximately in the middle of the crockery basket 2.

Der Aufbau des Koppelkopfs 8 ist in Fig. 6 bis 10 illustriert. Er besitzt ein ungefähr schuhförmiges Gehäuse, welches schwenkbar mit der Verbindungsleitung 9 verbunden ist. Diese Verbindung erlaubt eine Schwenkbewegung um eine Schwenkachse 34, die in der Achse der Verbindungsleitung 9 und somit im wesentlichen parallel zur Ausfahrrichtung des Geschirrkorbs 2 verläuft.The structure of the coupling head 8 is in Fig. 6 to 10 illustrated. He has an approximately shoe-shaped housing which is pivotally connected to the connecting line 9. This connection allows a pivoting movement about a pivot axis 34 which extends in the axis of the connecting line 9 and thus substantially parallel to the extension direction of the dish rack 2.

Am Koppelkopf 8 sind als Führungsorgane zwei voneinander beabstandete Rastmechanismen 10a, 10b bzw. lla, llb vorgesehen, in die je ein Draht 12 bzw. 13 des Geschirrkorbs eingerastet ist. Wie aus den Figuren ersichtlich, sind die Rastmechanismen so gestaltet, dass sie in der Lage sind, Zug- und Stosskräfte parallel zur Auszugsrichtung des Geschirrkorbs 2 zwischen den Drähten 12, 13 und dem Koppelkopf 8 zu übertragen, indem sie die Drähte bei Zug und Stoss von hinten bzw. vorne beaufschlagen. Sie erlauben jedoch seitliche Schwenkbewegungen des Koppelkopfes 8. Dies ist in Fig. 6 und 7 gezeigt, wo der Koppelkopf in zwei unterschiedlichen Schwenkstellungen dargestellt ist. Hierzu folgen die Drähte 12 bzw. 13 ungefähr tangential der Schwenkbahn des Koppelkopfs.On the coupling head 8 are provided as guide members two spaced latching mechanisms 10a, 10b and lla, llb, in each of which a wire 12 and 13 of the dish rack is engaged. As can be seen from the figures, the locking mechanisms are designed so that they are able to transmit tensile and impact forces parallel to the extension direction of the crockery basket 2 between the wires 12, 13 and the coupling head 8 by the wires in train and shock apply from behind or front. However, they allow lateral pivoting movements of the coupling head 8. This is in 6 and 7 shown where the coupling head is shown in two different pivot positions. To this end, the wires 12 and 13 approximately tangentially follow the pivoting path of the coupling head.

Die Schwenkbarkeit des Koppelkopfs 8 ist so gross, dass er in beiden gekippten Stellungen des Geschirrkorbs 2 im wesentlichen in eine senkrechte Stellung gebracht werden kann.The pivoting of the coupling head 8 is so large that it can be brought in two tilted positions of the crockery basket 2 in a substantially vertical position.

Wie insbesondere aus Fig. 9 ersichtlich, besitzt der Koppelkopf 8 eine Rückwand 14 und eine Kappe 15. Die Kappe 15 bildet die Vorderseite des Koppelkopfs 8 und besitzt eine Anschlussmanschette 16 für die Verbindungsleitung 9.As in particular from Fig. 9 can be seen, the coupling head 8 has a rear wall 14 and a cap 15. The cap 15 forms the front of the coupling head 8 and has a connection sleeve 16 for the connecting line. 9

Die Rückwand 14 besteht aus einer im wesentlichen flachen Platte, in welcher vier übereinander liegende Öffnungen 20 (20a, 20b, 20c, 20d) angeordnet sind. Für die in Fig. 1 - 5 dargestellte Ausführung des Geschirrspülers werden nur drei dieser Öffnungen benötigt und die Vierte kann permanent oder mit einer gefederten Klappe verschlossen sein. Die Funktion der vierten Öffnung, im vorliegenden Beispiel Öffnung 20d, wird weiter unten beschrieben.The rear wall 14 consists of a substantially flat plate, in which four superposed openings 20 (20a, 20b, 20c, 20d) are arranged. For the in Fig. 1-5 illustrated embodiment of Dishwashers require only three of these openings and the fourth can be permanently closed or with a spring-loaded flap. The function of the fourth opening, in the present example opening 20d, will be described below.

Vor jeder Öffnung ist eine Klappe 21 (21a, 21b, 21c, 21d) angeordnet, von denen in Fig. 10 nur Klappe 21d dargestellt ist.Before each opening a flap 21 (21a, 21b, 21c, 21d) is arranged, of which in Fig. 10 only flap 21d is shown.

Der Aufbau der Klappen 21 ist in Fig. 11 und 12 dargestellt. Jede Klappe 21 weist zwei seitliche Scharniere 22 auf, die an zwei Armen 23 angeordnet sind. Die Klappe 21 ist so ausgestaltet, dass sie die jeweilige Öffnung vollständig zu schliessen vermag.The construction of the flaps 21 is in FIGS. 11 and 12 shown. Each flap 21 has two lateral hinges 22 which are arranged on two arms 23. The flap 21 is designed so that it is able to completely close the respective opening.

Wie aus Fig. 9 und 10 ersichtlich, liegen die Scharniere 22 in Vertiefungen 25 der Rückwand 14, und werden von einer Leiste 26 der Kappe 15 am Herausfallen gehindert. Damit vereinfacht sich die Montage der Klappen 21. Sie werden in einem ersten Schritt in die Rückwand 14 und die Vertiefungen 25 eingelegt, worauf die Kappe 15 aufgesetzt wird, so dass die Klappen zwischen der Rückwand 14 und der Kappe 15 gehalten werden.How out Fig. 9 and 10 seen, the hinges 22 lie in recesses 25 of the rear wall 14, and are prevented by a strip 26 of the cap 15 from falling out. This simplifies the assembly of the flaps 21. They are inserted in a first step in the rear wall 14 and the recesses 25, whereupon the cap 15 is placed so that the flaps between the rear wall 14 and the cap 15 are held.

Bei jeder Klappe ist eine Feder 27 angeordnet, die als Rückstellmittel zum Schliessen der Klappe dient.In each flap, a spring 27 is arranged, which serves as a return means for closing the flap.

In der Rückwand 14, welche aus hartem Kunststoff besteht, ist eine Dichtmasse 28 aus weicherem Kunststoff eingegossen. Diese bildet um jede Öffnung 20 einen Dichtungsring, auf welchem die jeweilige Klappe 21 aufliegt. Gleichzeitig bildet die Dichtmasse eine Dichtung zwischen Rückwand 14 und Kappe 15.In the rear wall 14, which consists of hard plastic, a sealant 28 is molded of softer plastic. This forms around each opening 20 a sealing ring on which the respective flap 21 rests. At the same time the sealant forms a seal between the rear wall 14 and cap 15th

Die Öffnungen 20 sind in ihrem Querschnitt der Mündung 30 der Wasserzufuhrleitung 31 angepasst, die in Fig. 13 dargestellt ist. Wenn der Geschirrkorb 2 eingeschoben wird, so wird die Mündung 30 in eine der Öffnungen 20 eingeführt und stösst die jeweilige Klappe 21 auf. Dabei bildet die Dichtmasse 28 einen Dichtungsring um die Mündung 30, der diese gegen die Rückwand 14 abdichtet.The openings 20 are adapted in their cross-section of the mouth 30 of the water supply line 31, which in Fig. 13 is shown. When the crockery basket 2 is inserted, the mouth 30 is inserted into one of the openings 20 and abuts the respective flap 21. The sealant 28 forms a sealing ring around the mouth 30, which seals against the rear wall 14.

In der in Fig. 2 dargestellten unteren Horizontalstellung des Geschirrkorbs 2 wird die Mündung 30 in die obere Öffnung 20c eingeschoben, in der in Fig. 3 dargestellten unteren Horizontalstellung in die untere Öffnung 20a. In den beiden gekippten Stellungen nach Fig. 4 und 5 liegt die Mündung etwa auf der Höhe der mittleren Öffnung 20b und wird in diese eingeführt.In the in Fig. 2 shown lower horizontal position of the crockery basket 2, the mouth 30 is inserted into the upper opening 20c, in the in Fig. 3 shown lower horizontal position in the lower opening 20a. In the two tilted positions after 4 and 5 the mouth is approximately at the height of the central opening 20b and is inserted into this.

Das von der Zufuhrleitung 31 kommende Wasser tritt durch die jeweils geöffnete Klappe 20 in den Koppelkopf 8 ein und gelangt von dort über die Verbindungsleitung 9 in den Sprüharm 7. Die nicht benutzten Öffnungen werden dank der Kraft der Federn 27 geschlossen gehalten.The coming of the supply line 31 water enters through the respective open flap 20 in the coupling head 8 and from there via the connecting line 9 in the spray arm 7. The unused openings are kept closed 27 thanks to the force of the springs.

Die Schwenkbarkeit des Koppelkopfes wird dabei benötigt, um trotz der Verkippung zu gewährleisten, dass die jeweilige Öffnung genau über der Mündung 30 zu liegen kommt. Um den Koppelkopf in die jeweils richtige Lage zu schwenken, sind in der Mündung 30 spitz zulaufende Führungsplatten 32 vorgesehen, die als Führungsmittel zum Zentrieren der jeweiligen Öffnung 20 auf der Mündung 30 dienen.The pivoting of the coupling head is required to ensure despite the tilting that the respective opening comes to lie exactly over the mouth 30. In order to pivot the coupling head in the respectively correct position, tapered guide plates 32 are provided in the mouth 30, which serve as guide means for centering the respective opening 20 on the mouth 30.

Wie oben erwähnt, ist in der Rückwand 14 noch eine zusätzliche vierte Öffnung 20d vorgesehen. Diese erlaubt es, die relative Position der Schienen 6 gegenüber der Wasserzufuhrleitung um einen Öffnungsabstand zu ändern, ohne dass der Kopplungskopf ausgewechselt werden muss.As mentioned above, an additional fourth opening 20d is provided in the rear wall 14. This makes it possible to change the relative position of the rails 6 with respect to the water supply line by an opening distance, without the coupling head must be replaced.

Wie insbesondere aus Fig. 10 ersichtlich, sind die Öffnungen 20 länglich ausgestaltet, d.h. sie besitzen in Horizontalrichtung (d.h. in Schwenkrichtung) höheren Durchmesser als senkrecht dazu. Diese Massnahme erlaubt bei gegebenen Vertikalabstand eine Vergrösserung der Querschnittfläche der Öffnungen.As in particular from Fig. 10 can be seen, the openings 20 are elongated, ie they have in the horizontal direction (ie in the pivoting direction) higher diameter than perpendicular thereto. This measure allows for a given vertical distance an enlargement of the cross-sectional area of the openings.

Insbesondere aus Fig. 1 ist ersichtlich, dass der Koppelkopf 8 ungefähr aber nicht genau in der Mitte der Rückwand des Geschirrkorbs 2 angeordnet ist. Dies hat den Vorteil, dass der hintere Teil des Geschirrkorbs in zwei unterschiedlich grosse Bereiche unterteilt wird, so dass auch sehr grosses Geschirrgut untergebracht werden kann. Die leicht asymmetrische Positionierung des Koppelkopfs 8 führt aber dazu, dass seine Höhe in den beiden gekippten Stellungen nach Fig. 4 und 5 nicht genau gleich ist. Deshalb ist der Koppelkopf 8 so gelagert, dass er etwas Spiel in vertikaler Richtung besitzt.In particular from Fig. 1 it can be seen that the coupling head 8 approximately but not exactly in the middle the rear wall of the crockery basket 2 is arranged. This has the advantage that the rear part of the dish rack is divided into two different sized areas, so that even very large dishes can be accommodated. However, the slightly asymmetric positioning of the coupling head 8 causes its height in the two tilted positions 4 and 5 not exactly the same. Therefore, the coupling head 8 is supported so that it has some play in the vertical direction.

Wie aus Fig. 9 ersichtlich, ist die mittlere Öffnung gegen die Schwenkachse 34 des Koppelkopfs vertikal versetzt. Dies reduziert die auf die Mündung 30 wirkenden Kräfte zur Winkelpositionierung des Koppelkopfs.How out Fig. 9 can be seen, the central opening is offset vertically against the pivot axis 34 of the coupling head. This reduces the force acting on the mouth 30 forces for angular positioning of the coupling head.
