Description

Die Erfindung betrifft eine Einrichtung zur Abgabe wenigstens einer Waschmittelsubstanz für eine Wäschebehandlungsmaschine mit einer in einem Laugenbehälter drehbar gelagerten Trommel, umfassend einen Spülkasten mit als Schub ausgebildeten Fächern für unterschiedliche Waschsubstanzen, die programmgesteuert für entsprechende Waschprogramme abrufbar sind, wobei die Waschmittelsubstanzen mittels Wasserzulaufdüsen, die mit den Fächern in Wirkverbindung stehen, in den Laugenbehälter einspülbar sind.The invention relates to a device for dispensing at least one detergent substance for a laundry treatment machine with a drum rotatably mounted in a tub, comprising a cistern with trained as a thrust trays for different washing substances that are programmatically available for corresponding washing programs, the detergent substances by means of water inlet nozzles with the subjects are in operative connection, can be flushed into the tub.

Aus dem Stand der Technik sind unterschiedliche Ausführungsformen von Einrichtungen zur Abgabe von Waschmittelsubstanzen für den Waschprozess bei Waschmaschinen bekannt. Vornehmlich sind diese insbesondere in der Frontseite des Maschinengehäuses angeordnet und sind hierbei als Schub ausgebildet. Der Schub umfasst hierbei Fächer, in denen die entsprechenden Waschmittelsubstanzen aus dem Schubfach heraus gespült werden, die dann in dem Laugenbehälter für den Waschprozess bereit gestellt werden.Various embodiments of devices for dispensing detergent substances for the washing process in washing machines are known from the prior art. Notably, these are arranged in particular in the front side of the machine housing and are in this case designed as a thrust. The thrust here comprises compartments in which the corresponding detergent substances are rinsed out of the drawer, which are then provided in the tub for the washing process.

So ist beispielsweise aus der US 2008/0078211 A1 eine Wäschebehandlungsmaschine bekannt, bei der insbesondere die einzelnen in dem Schub vorgehaltenen Fächer mit gesonderten Zuflüssen versehen sind, um auf diese Weise jeweils das abzurufende Fach auszuspülen. Zum Ausspülen der unterschiedlichen Fächer ist es hierbei erforderlich, beispielsweise einen Verteilerfinger vorzusehen, der über eine Wasserweiche gesteuert wird, so dass entsprechend das mit der Waschmittelsubstanz enthaltene Fach ausgespült wird. Somit sind hierbei Mehrfach-Zulaufventile mit so genannten "Crossflow-Systemen" erforderlich.For example, from the US 2008/0078211 A1 a laundry treatment machine is known in which in particular the individual held in the drawer compartments are provided with separate tributaries, in order to flush out the compartment to be retrieved in this way. For rinsing out the different compartments, it is necessary in this case to provide, for example, a distributor finger, which is controlled via a water diverter, so that the compartment containing the detergent substance is correspondingly rinsed out. Thus, multiple inlet valves with so-called "crossflow systems" are required.

Eine andere Ausführungsform ist aus der DE 103 55 671 A1 bekannt, die eine Vorrichtung zur Abgabe mindestens einer Waschsubstanz in einer Waschmaschine offenbart. Bei dieser Art der Ausgestaltung ist das Schubfach derart ausgebildet, dass versetzbare Trennwände in dem Schub vorgesehen sind, um auf diese Weise eine gewisse Mengenvorgabe der Waschmittelsubstanz zu liefern. Bei dieser Art der Ausführungsform ergibt sich der Nachteil, dass insbesondere eine Abdichtung der zueinander liegenden Fächer infolge der Abtrennwand nicht gegeben ist.Another embodiment is known from DE 103 55 671 A1 discloses a device for dispensing at least one washing substance in a washing machine. In this type of embodiment, the drawer is designed such that displaceable partitions are provided in the thrust to provide in this way a certain amount of detergent substance. In this type of embodiment, there is the disadvantage that, in particular, a seal of the compartments lying to each other due to the partition wall is not given.

Eine weitere Ausführungsform ist aus der US 3,988,908 A bekannt, wobei bei dieser Ausführungsform Einzelfächer vorgesehen sind, die über einen Steuermechanismus bewegbar angeordnet sind, um auf diese Weise die entsprechende Waschmittelsubstanz abzurufen.Another embodiment is known from US 3,988,908 A known, wherein in this embodiment individual compartments are provided, which are arranged movably via a control mechanism, in order to retrieve the corresponding detergent substance in this way.

Als nachteilig bei den aus dem Stand der Technik bekannten Ausführungsformen wird es im Wesentlichen angesehen, dass einerseits die Abdichtung der beweglichen Wasserführungen sehr aufwändig ist, oder andererseits mehrere Ventilblöcke erforderlich sind, die eine aufwändige Ansteuerung mit sich bringen.A disadvantage of the known from the prior art embodiments, it is essentially considered that on the one hand, the sealing of the movable water ducts is very complex, or on the other hand, several valve blocks are required, which bring a complex control with it.

Aus der DE 16 10 185 A1 ist eine Einrichtung zur Abgabe einer Waschmittelsubstanz bekannt, die als Drehkarussel angeordnete Fächer aufweist, die mittels einer in der Drehachse befindlichen, feststehenden Düse ausgespült werden können, je nachdem, welches Fach sich im Wirkbereich der Düse befindet.From the DE 16 10 185 A1 A device for dispensing a detergent substance is known, which has compartments arranged as a rotary carousel, which can be flushed out by means of a fixed nozzle located in the axis of rotation, depending on which compartment is located in the effective region of the nozzle.

Aus der JP 2000 245993 A ist eine Einrichtung zur Abgabe einer Waschmittelsubstanz bekannt, bei der das Fach zur Aufnahme der Waschmittelsubstanz mit mehreren, flügelartigen Stegen unterteilt ist. Mittels einer schräggestellten Düse werden die Stege mit Wasser angeströmt, welches zuvor mit Pressluft eingeleitet wurde. Aufgrund der angeströmten Stege wird die Kammer in eine Rotation gebracht, wodurch die Vermischung der Waschmittelsubstanz mit dem Wasser verbessert werden soll. Hier ist keine Unterteilung in einzelne Fächer vorgesehen, so dass unterschiedliche Waschmittelsubstanzen für die verschiedenen Abschnitte eines Waschprogramms nicht vorgehalten werden können.From the JP 2000 245993 A a device for dispensing a detergent substance is known, in which the compartment for receiving the detergent substance with a plurality of wing-like webs is divided. By means of a slanted nozzle, the webs are supplied with water, which was previously introduced with compressed air. Due to the flowed webs, the chamber is brought into rotation, whereby the mixing of the detergent substance to be improved with the water. Here, no division into individual compartments is provided, so that different detergent substances for the different sections of a washing program can not be kept.

Der Erfindung stellt sich somit das Problem, eine Einrichtung zur Abgabe wenigstens einer Waschmittelsubstanz für eine Wäschebehandlungsmaschine derart weiter zu bilden, die zum Ausspülen der unterschiedlichen Fächer des Schubkastens auf einen Verteiler bzw. eine Wasserweiche verzichtet, um auf diese Weise Leckagen in den angewählten Positionen der einzelnen Fächer zu vermeiden.The invention thus presents the problem of further developing a device for dispensing at least one detergent substance for a laundry treatment machine, which dispenses with rinsing the different compartments of the drawer on a distributor or a water diverter so as to leak in the selected positions of the to avoid individual subjects.

Erfindungsgemäß wird dieses Problem durch den Hauptanspruch 1 gelöst; vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.According to the invention this problem is solved by the main claim 1; advantageous embodiments of the invention will become apparent from the dependent claims.

Bei der erfindungsgemäßen Lösung wird erreicht, dass der Waschautomat einen starren Wasseranschluss mit nur einer Düsengeometrie erhält, die mittig im Spülkastendeckel vorgesehen ist. Dabei besteht der Wasseranschluss aus einem Einfach-Zulaufventil mit starrer Anbindung an den Einspülkasten. Somit wird das Ziel erreicht, dass aufgrund der erfindungsgemäßen Ausbildung auf eine aufwändige Ventil- und Steuertechnik verzichtet werden kann, wobei diese sich hier lediglich darauf beschränkt, dass der Einspülkasten zu bewegen ist in Abhängigkeit zu der Wasserzufuhr für den entsprechenden Waschgang.In the solution according to the invention it is achieved that the washing machine receives a rigid water connection with only one nozzle geometry, which is provided centrally in the cistern lid. The water connection consists of a single inlet valve with a rigid connection to the dispenser. Thus, the goal is achieved that due to the inventive design can be dispensed with a complex valve and control technology, which here is limited only to the fact that the Einspülkasten is to move in dependence on the water supply for the corresponding wash cycle.

Erfindungsgemäß erfolgt der Wasserzulauf über eine oberhalb des Spülkastens starr angeordnete Düse, deren Düsengeometrie derart ausgebildet ist, dass sie den Öffnungsquerschnitt der unter der Düse beweglich angeordneten Fächer abdeckt. Hierbei ist die Düse etwa mittig über dem Einspülkasten angeordnet. Gemäß der Erfindung sind die Fächer in dem Spülkasten in einem drehbar gelagerten Karussell angeordnet. Dabei weist der Spülkasten bzw. die Aufnahme für das Karussell eine Topfform mit einer im Boden geöffneten Kulisse auf. In der Topfform ist das mit Fächern versehene Karussell drehbar eingesetzt. Die im Boden der Aufnahme angeordnete Kulisse stellt eine Öffnung zwischen dem einzelnen auszuspülenden Fach im Karussell und dem Zulauf zum Laugenbehälter bereit.According to the invention, the water inlet takes place via a nozzle arranged rigidly above the cistern, the nozzle geometry of which is designed such that it covers the opening cross-section of the compartments arranged movably below the nozzle. Here, the nozzle is approximately in the middle arranged above the dispenser. According to the invention, the compartments are arranged in the cistern in a rotatably mounted carousel. In this case, the cistern or the receptacle for the carousel on a pot shape with an open in the ground backdrop. In the cup shape, the carousel provided with compartments is rotatably inserted. The arranged in the bottom of the recording backdrop provides an opening between the individual rinsing compartment in the carousel and the inlet to the tub ready.

Es versteht sich nun von selbst, dass je nach Abruf der Waschmittelsubstanz das Karussell mit seinen Fächern entsprechend über die Kulissenöffnung gedreht wird, so dass dem entsprechend programmierten Waschprogramm die entsprechende Waschmittelsubstanz zugeführt wird.It goes without saying that depending on the retrieval of the detergent substance, the carousel is rotated with its subjects according to the gate opening, so that the corresponding programmed washing program, the corresponding detergent substance is supplied.

Dabei besteht in vorteilhafter Weise das Karussell aus einer Kreisscheibe, in der vier geöffnete Kreissegmente angeordnet sind, unter denen jeweils Seitenwände in Form eines Kreuzes ange formt sind. Die kreuzartig unterhalb der Kreisscheibe angeformten Seitenwände bilden mit der umlaufenden Topfwand sowie dem Karussellboden die drehbar gelagerten Fächer. Somit wird sichergestellt, dass hier ein dichtendes sich bewegendes Fach bereit gestellt wird, das entsprechend einer Entleerung in die Position unterhalb der Düse zugeführt werden kann. Im Topfboden ist in der Drehachse des Karussells ein Greifelement vorgesehen, welches im eingeschobenen Zustand des Schubes, welches den Topf mit dem darin befindlichen Karussell enthält, mit einer Antriebswelle in Wirkverbindung tritt. Somit wird entsprechend der Vorgabe durch das Programm das Karussell über die Antriebswelle in der geschlossenen Topfform gedreht, so dass dann entsprechend das Fach bewegt wird, welches entleert werden soll. Ist das Fach bündig mit der Düsengeometrie, so wird der Wasserzulauf freigegeben, so dass die eindringende Flüssigkeit mit der Waschmittelsubstanz über den Zulauf zum Laugenbehälter abgeführt werden kann.In this case, the carousel advantageously consists of a circular disk in which four open circular segments are arranged, under each of which side walls are in the form of a cross are formed. The cross-shaped integrally formed below the circular disk side walls form with the peripheral pot wall and the carousel floor, the rotatably mounted compartments. This ensures that a sealing, moving compartment is provided here, which can be supplied to the position below the nozzle in accordance with an emptying. In the bottom of the pot a gripping element is provided in the axis of rotation of the carousel, which in the inserted state of the thrust, which contains the pot with the carousel therein, comes into operative connection with a drive shaft. Thus, according to the specification by the program, the carousel is rotated via the drive shaft in the closed pot shape, so that then the tray is moved accordingly, which is to be emptied. If the compartment is flush with the nozzle geometry, the water inlet is released, so that the penetrating liquid can be removed with the detergent substance through the inlet to the tub.

Zur Herstellung der schubartigen Anordnung des Karussells wird vorgesehen, dass oben an der Topfwand ein als Rahmen umgebener Randbereich angeformt ist, der in seitlich am Gehäuse des Einspülkastens angeordnete Führungsnuten greift. Wie schon beschrieben, ist hierbei die Düsengeometrie entsprechend dem Öffnungsquerschnitt eines Viertelkreis-Segmentes ausgebildet, somit wird gewährleistet, dass eine dichte Verbindung bzw. ein dichter Abschluss zur Viertelkreis-Segmentöffnung gegeben ist.In order to produce the thrust-like arrangement of the carousel, provision is made for an edge region surrounded by a frame to be formed on top of the pot wall, which engages in guide grooves arranged laterally on the housing of the dispensing box. As already described, in this case the nozzle geometry is designed in accordance with the opening cross section of a quarter-circle segment, thus ensuring that a tight connection or a tight seal to the quarter circle segment opening is provided.

The

Waschmittelsubstanzen werden hierbei mittels einer Wasserzulaufdüse 8, die mit denDetergent substances are in this case by means of a water inlet nozzle 8, with the

Fächern 6 in Wirkverbindung steht, in den Laugenbehälter 3 eingespült. Der Wasserzulauf in die Einrichtung 2 erfolgt unter Zuhilfenahme des steuerbaren Ventils 7a, wobei das eingelassene Wasser durch die Leitung 7 zur Düse 8 fließt.Compartments 6 is in operative connection, flushed into the tub 3. The water inlet into the device 2 takes place with the aid of the controllable valve 7 a, wherein the introduced water flows through the line 7 to the nozzle 8.

Wie insbesondere aus den Figuren 2 und 3 zu erkennen ist, erfolgt der Wasserzulauf über eine über dem Spülkasten 5 starr angeordnete Düse 8, deren Düsengeometrie 9 derart ausgebildet ist, dass sie den Öffnungsquerschnitt des unterhalb der Düse 8 beweglich angeordneten Faches 6.2 abdeckt. Dies ist in der Figur 2 angedeutet, wo die Düsengeometrie 9 auf die Fachgeometrie, hier in dem Öffnungsquerschnitt des Faches 6.2, abgestellt ist. Das gilt ebenso für die anderen Fächer 6.1, 6.3, 6.4, die zumindest in etwa den gleichen Öffnungsquerschnitt und etwa die gleiche Öffnungsform aufweisen. Dabei ist die Düse 8 etwa mittig über dem Spülkasten 5 angeordnet, wobei die Fächer 6.1, 6.2, 6.3, 6.4 in einem drehbar gelagerten Karussell 10 angeordnet sind, das sich seinerseits im dem Spülkasten 5 bzw. in einer Aufnahme 11 a befindet. Dies ist insbesondere aus den Figuren 2, 4 und 5 zu erkennen, wobei hierbei der Aufnahme 11a des Karussells 10 eine Topfform mit einer im Boden 11 geöffneten Kulisse 12 aufweist. Dies ist insbesondere in der Figur 3 zu erkennen, in der der Spülkasten 5 mit ausgezogenen Fächereinsatz ausgezogen dargestellt ist, wobei hier der Boden 11 der Karussellaufnahme 11 a mit der geöffneten Kulisse 12 und dem Boden 10a des Karussells 10 (Fig. 4) zu erkennen ist.As in particular from the Figures 2 and 3 can be seen, the water inlet via a rigidly arranged above the cistern 5 nozzle 8, the nozzle geometry 9 is formed such that it covers the opening cross-section of the below the nozzle 8 movably arranged compartment 6.2. This is in the FIG. 2 indicated where the nozzle geometry 9 on the subject geometry, here in the opening cross-section of the compartment 6.2, is turned off. This also applies to the other subjects 6.1, 6.3, 6.4, which have at least approximately the same opening cross-section and approximately the same opening shape. In this case, the nozzle 8 is arranged approximately centrally above the cistern 5, wherein the compartments 6.1, 6.2, 6.3, 6.4 are arranged in a rotatably mounted carousel 10, which in turn is in the cistern 5 and in a receptacle 11 a.

This is especially true in the FIG. 3 can be seen, in which the cistern 5 is shown pulled out with extended tray insert, in which case the bottom 11 of the carousel receptacle 11 a with the open gate 12 and the bottom 10 a of the carousel 10 ( Fig. 4 ) is recognizable.

Dabei ist in der topfförmigen Aufnahme 11a das mit Fächern 6.1, 6.2, 6.3 und 6.4 vorgesehene Karussell 10 drehbar eingesetzt. Die im Boden 11 angeordnete Kulisse 12 des Spülkastens 5 stellt eine Öffnung zwischen den einzelnen auszuspülenden Fächern 6.1, 6.2, 6.3 und 6.4 im Karussell 10 und dem Zulauf 13 zum Laugenbehälter 3 her. Diese Situation ist insbesondere aus der Figur 1 zu erkennen, wo insbesondere die Verbindung bzw. der Zulauf 13 vom Spülkasten 5 zum Laugenbehälter 3 dargestellt ist.In this case, the carousel 10 provided with compartments 6.1, 6.2, 6.3 and 6.4 is rotatably inserted in the cup-shaped receptacle 11a. The arranged in the bottom 11 slide 12 of the cistern 5 provides an opening between the individual auszuspülenden subjects 6.1, 6.2, 6.3 and 6.4 in the carousel 10 and the inlet 13 to the tub 3 ago. This situation is particular from the FIG. 1 to recognize where in particular the connection or the inlet 13 from the cistern 5 to the tub 3 is shown.

Wie insbesondere in der Zusammenschau der Figuren 2, 3 und 4 ersichtlich ist, besteht das Karussell 10 aus einer Kreisscheibe 14, in der vier geöffnete Kreissegmente angeordnet sind. Unterhalb der geöffneten Kreissegmente, die den Fächern 6.1, 6.2, 6.3, 6.4 entsprechen, sind die jeweiligen Seitenwände 15 und 16 in Form eines Kreuzes angeformt, wie dies insbesondere in der Figur 2 zu erkennen ist. Dabei bilden die kreuzartig unterhalb der Kreisscheibe 14 angeformten Seitenwände 15 und 16 mit der umlaufenden Topfwand 17 sowie dem Karussellboden 10a die drehbar gelagerten Fächer 6.1, 6.2, 6.3 und 6.4.As in particular in the synopsis of Figures 2 . 3 and 4 it can be seen, the carousel 10 consists of a circular disc 14, in which four open circle segments are arranged. Below the open circle segments, which correspond to the subjects 6.1, 6.2, 6.3, 6.4, the respective side walls 15 and 16 are formed in the shape of a cross, as shown in particular in the FIG. 2 can be seen. In this case, the cruciform formed below the circular disc 14 side walls 15 and 16 with the peripheral pot wall 17 and the carousel floor 10a, the rotatably mounted compartments 6.1, 6.2, 6.3 and 6.4.

In Fig. 5 ist zu erkennen, dass das Fach 6.4 für pulverförmiges Waschmittel vorgesehen ist, da dieses Fach 6.4 nur in dieser Einspülposition zum Topfinneren hin offen ist. Das bedeutet, sobald das Wasser aus der Düse 8 in das Fach 6.4 gelangt, wird das pulverförmige Waschmittel aus dem Fach 6.4 in den Topf 11 a bzw. aus der Kulisse 12 im Topfboden 11 ausgespült und gemeinsam mit dem Wasser durch den Laugenbehälterzulauf 13 (Fig. 1) in den Laugenbehälter 3 (Fig. 1) geleitet. Das Karussell 10 ist in einer Ausführung mit einer äußeren, umlaufenden Wand (nicht dargestellt) versehen, bei der jedes als Kreissegment ausgebildete Fach 6.1, 6.3 und 6.4 jeweils eine Öffnung besitzt, die mit einer beweglichen Klappe (nicht dargestellt) verschließbar ist. Die Klappe wird durch eine Kulissenführung nur dann geöffnet, sobald sich das dazugehörige Fach in der Einspülposition unterhalb der Düse 8 befindet bzw. dorthin bewegt wird. Alternativ kann die Klappe programmgesteuert mittels eines Aktors (nicht dargestellt) bewegt werden. Gemäß Fig. 4 ist für das Einspülen von flüssigen Behandlungsmitteln wie Weichspüler das Fach 6.2 mit einem Saugheber 6.20 versehen, damit das flüssige Behandlungsmittel nicht sofort aus der Kammeröffnung heraus in den Topf 11a bzw. in den Spülkasten 5 und weiter in den Laugenbehälter 3 fließt.In Fig. 5 It can be seen that the compartment 6.4 is provided for powder detergent, since this compartment is 6.4 open only in this dispensing position to the interior of the pot. That means, once the water from the nozzle 8 enters the compartment 6.4, the powdered detergent is rinsed from the compartment 6.4 in the pot 11 a or from the backdrop 12 in the bottom of the pot 11 and together with the water through the tub inlet 13 ( Fig. 1 ) in the tub 3 ( Fig. 1 ). The carousel 10 is provided in one embodiment with an outer, circumferential wall (not shown) in which each formed as a circular segment compartment 6.1, 6.3 and 6.4 each have an opening which is closed with a movable flap (not shown). The flap is opened by a slotted guide only when the corresponding compartment is in the dispensing position below the nozzle 8 and is moved there. Alternatively, the flap can be moved programmatically by means of an actuator (not shown). According to Fig. 4 is for the flushing of liquid treatment agents such as fabric softener compartment 6.2 provided with a siphon 6.20, so that the liquid treatment agent does not immediately from the chamber opening out into the pot 11a and in the cistern 5 and further into the tub 3 flows.

Im Boden 11 des Topfes 11 a ist zur Bereitstellung der Drehung des Karussells 10 bzw. zur Kraftübertragung von einem Aktor oder Motor (nicht dargestellt) in der Drehachse 18 des Karussells 10 ein Greifelement 19 vorgesehen, wie dies in der Situation der Figur 3 dargestellt ist. Dieses Greifelement 19 tritt im eingeschobenen Zustand, dargestellt in der Figur 2 des Schubes, mit einer Antriebswelle 20, die unterhalb des Spülkastenbodens 21 angesetzt ist, in Wirkverbindung. Wie die Antriebswelle 20 sich darstellt und die Verbindung des Greifelementes 19 ist auch aus der Figur 4 ersichtlich, wo im Boden 21 des Spülkastens 5 ein drehbar gelagerter Nocken 22 zu erkennen ist, der insbesondere in das Greifelement 19 (Fig. 3) einfährt, wenn das Karussell 10 in den Spülkasten 5 eingeschoben ist, wobei sich aufgrund der Formgebung der konkaven Wölbungen 23 des Greifelementes 19 eine Justierung des Steges 22 ergibt, so dass die Wirkverbindung hergestellt wird, auch wenn der Steg 22 bzw. das Greifelement 19 nicht exakt ausgerichtet ist.In the bottom 11 of the pot 11 a is provided to provide the rotation of the carousel 10 and the power transmission of an actuator or motor (not shown) in the axis of rotation 18 of the carousel 10, a gripping member 19, as in the situation of FIG. 3 is shown. This gripping element 19 occurs in the inserted state, shown in the FIG. 2 the thrust, with a drive shaft 20 which is attached below the Spülkastenbodens 21, in operative connection. As the drive shaft 20 is shown and the connection of the gripping member 19 is also from the FIG. 4 can be seen where in the bottom 21 of the cistern 5, a rotatably mounted cam 22 can be seen, in particular in the gripper element 19 (Fig. Fig. 3 ) retracts when the carousel 10 is inserted into the cistern 5, wherein due to the shape of the concave curvatures 23 of the gripping member 19 results in an adjustment of the web 22, so that the operative connection is made, even if the web 22 and the gripping member 19th is not exactly aligned.

Wie aus den Figuren 2 und 3 zu sehen ist, ist oben an der Topfwand 17 ein als Rahmen 25 umgebener Randbereich angeformt, der in seitlich am Gehäuse des Spülkastens 5 angeordnete Führungsnuten 26 und 27 greift. Somit ist eine sichere Führung der drehbar gelagerten Fächer 6.1, 6.2, 6.3 und 6.4 gegeben, die auch als Schub, dargestellt in der Figur 5, zur Beschickung herausgezogen werden können, bzw. dann für den Waschprozess gemäß der Figur 6 eingefahren werden können. Wie die Figuren 5 und 6 zeigen, ist der Spülkasten 5 mit einem Deckel 28 versehen, der entsprechend eine Öffnung aufweist die mit der Düsengeometrie 9 bündig ist, so dass insbesondere der Öffnungsquerschnitt des Deckels 28 dichtend mit der Düsengeometrie 9 zur Anlage kommt, und jedes einzelne Fach 6.1, 6.2, 6.3 bzw. 6.4 abgedichtet ausgespült werden kann, sofern es durch die Steuerung des Programms gedreht wird. Die Düsengeometrie 9 ist hierbei entsprechend dem Öffnungsquerschnitt eines der Viertelkreis-Segmente ausgebildet.Like from the Figures 2 and 3 can be seen, at the top of the pot wall 17 is formed as a frame 25 bordered edge region which engages in laterally arranged on the housing of the cistern 5 guide grooves 26 and 27. Thus, a secure guidance of the rotatably mounted compartments 6.1, 6.2, 6.3 and 6.4 is given, which also as a thrust, shown in the FIG. 5 , can be pulled out to feed, or then for the washing process according to the FIG. 6 can be retracted. As the Figures 5 and 6 show, the cistern 5 is provided with a cover 28 having an opening corresponding to the nozzle geometry 9 is flush, so that in particular the opening cross section of the lid 28 sealingly comes into contact with the nozzle geometry 9, and each individual compartment 6.1, 6.2, 6.3 or 6.4 can be flushed out, if it is rotated by the control of the program. The nozzle geometry 9 is in this case formed according to the opening cross-section of one of the quadrant segments.
