- a dishwashing machine with such a device in the form of an addition unit for adding detergent in a rinsing liquor in which a liquid feed is provided in the addition unit for rinsing the cleaner from the addition unit.
- a partial flow of the circulated rinsing liquor is conveyed via a valve and an additional line into the addition unit. Once the cleaner has been added, the line and the valve are without function until the program is restarted.
- a dishwashing machine with an addition unit which has a box-shaped container with an opening. The container is locked in a position in which the opening is closed and facing in a lateral direction.
- Object of the present invention is to provide a dishwasher with a device for adding detergent with high Aus Guessschreib.
- the spray nozzle may be part of the spray system. This is usually arranged in three levels in the washing compartment, for example in the form of rotatable spray arms or fixed nozzle systems.
- the bypass line then ends, for example, at an additional nozzle of the spray system.
- the movable part can be moved from a basic position to an additional position.
- the container In the basic position, the container is closed relative to the washing compartment so that the detergent is protected from contact with the washing liquor.
- the container In the supply position, the container is then open in the direction of the washing compartment, so that the washing solution can rinse the detergent into the washing compartment.
- the movable part can initiate the flushing process when opening the container similar to a switch and terminate this when closing the container. This means that it is always possible to add just as much rinsing liquor to the cleaning agent as is necessary for its dissolution and rinsing.
- the spray element may be, for example, a spray nozzle or a system of multiple spray nozzles. Both can be arranged fixed or movable in the washing compartment.
- the dishwasher according to the invention pursues the concept that the elements provided for rinsing out the cleaning agent from the container can be used during an entire washing program. This avoids that the rinsing liquor stops in the lines over a longer period of time and can form deposits.
- the pivotable container can be arranged as a whole, for example, in a housing open to the washing compartment to move. In the basic position closes one
- the entire container from the basic position in the addition position is pivotable.
- the container can be displaceably arranged or rotatably supported along a curved path. This form of storage is easy and inexpensive to produce.
- the rotatable connection of the container with the housing can be carried out, for example, in the form of two pivot points left and right of the container bottom near the Spülraumwand in which two pins arranged on the container engage in corresponding recesses of the housing.
- This form of storage allows the pivoting of the container out of the housing in the direction of Spülraum to a filling position. In the filling position, the interior of the container is accessible from the side of the washing compartment. In this position, the container can then be filled manually, for example by a user with detergent.
- the limitation of the pivoting movement of the container in the direction of the washing compartment can be effected by stops which are arranged on the container and / or on the housing.
- latching means can be arranged on the container, which interact with counter-latching means on the housing for latching the container with the housing in the basic position.
- the movement of the container from the filling position to the basic position and the local fixation can - as well as the filling - automatically or programmatically controlled or done manually by a user.
- all movements of the container can also be effected by an actuator, for example in the form of a motor, a coil or a bimetal.
- the bimetal can for example cause or effect the movement of the container depending on the temperature. This is a purely mechanical control. When using a motor, this can be controlled by a control device, for example, program sequence-dependent, to then cause the movement of the container.
- the supply of the rinsing liquor can also take place as a function of the movement of the container between the basic position and the delivery position.
- the position of the container in the supply position corresponds to that of the filling position.
- a second valve for controlling the volume flow of the rinsing liquor which is in operative connection with the container.
- the movement of the valve actuator can generally be effected in dependence on the movement or position of the container.
- the second valve may for example be closed in the basic position of the container and be open in the supply position of the container. This ensures that only rinse liquor enters the container when it is open towards the dishwasher.
- This can be realized, for example, with an actuator disposed on the container, which is in the addition position with the second valve in contact and then completely opens. Upon movement of the container from the supply position to the home position, the contact between the actuator and the valve is interrupted again, and the valve is closed.
- a sensor may also be used which detects the respective position of the container without contact and accordingly causes the opening and closing of the second valve by means of the control device. The opening and closing of the valve can be caused for example by electric actuators.
- the second valve can be opened corresponding to the pivotal movement of the container between the basic position and the Ausêtdian.
- a corresponding position of the valve actuator is adjustable for each pivot position between the basic position and the addition order.
- the coupling can be mechanical, electrical or sensory.
- a mechanical coupling can be designed, for example, in the form of a linkage or a gearbox.
- a potentiometer arranged at the pivot point of the container or container part can be connected to an electric actuator.
- the movement or the pivoting position of the container is detected by means of one or more sensors. These are connected for example via a control unit with the actuator of the valve.
- the coupling makes it possible to adapt the amount of rinsing liquor required for rinsing the cleaning agent to the respective position of the container. In this way, the detergent can be evenly rinsed or dissolved. An abrupt flushing of the entire cleaning agent, which then dissolves completely in the washroom, can thus be avoided.
- first and second valve instead of a first and second valve, only one valve may be provided, which combines the functions of both valves together.

Description
Die vorliegende Erfindung betrifft ein wasserführendes Haushaltsgerät, insbesondere Geschirrspülmaschine, mit einer Vorrichtung zur Zugabe von Reinigungsmittel in einen von Wänden begrenzten Spülraum des wasserführenden Haushaltsgeräts, die im Spülraum zumindest ein Sprühsystem zur Reinigung von Spülgut aufweist, mit einem im Spülraum angeordneten Behältnis zur Aufnahme von Reinigungsmittel.The present invention relates to a water-conducting household appliance, in particular dishwasher, with a device for adding detergent in a limited space of walls washing compartment of the water-bearing household appliance, which has at least one spray system for cleaning items to be washed in the washing compartment, with a container arranged in the washing compartment for receiving detergent ,
Aus der
Aufgabe der vorliegenden Erfindung ist es, eine Geschirrspülmaschine mit einer Vorrichtung zur Reinigungsmittelzugabe mit hoher Ausspülsicherheit bereitzustellen.Object of the present invention is to provide a dishwasher with a device for adding detergent with high Ausspülsicherheit.
Diese Aufgabe wird bei einem gemäß dem Oberbegriff des Anspruchs 1 ausgestalteten wasserführenden Haushaltsgerät dadurch gelöst, dass wenigstens eine Sprühdüse benachbart zum Behältnis angeordnet ist, die über eine Versorgungsleitung, mit Spülflotte versorgt werden kann, wobei das gesamte Behältnis zwischen einer Grundstellung und einer Zugabestellung schwenkbar ist, wobei in dieser Stellung eine Öffnung des Behältnisses in den Spülraum hinein ragt, wodurch das Reinigungsmittel durch die wenigstens eine Sprühdüse aus dem Behältnis heraus in den Spülraum der Geschirrspülmaschine gespült werden kann.This object is achieved in a configured according to the preamble of claim 1 water-conducting household appliance in that at least one spray nozzle is arranged adjacent to the container, which can be supplied via a supply line, with rinsing liquor, wherein the entire container between a basic position and an additional position is pivotable, wherein in this position, an opening of the container in the washing room protrudes into, whereby the detergent through the at least a spray nozzle can be rinsed out of the container into the washing compartment of the dishwasher.
Die Sprühdüse kann Teil des Sprühsystems sein. Dieses ist üblicherweise in drei Ebenen im Spülraum angeordnet, zum Beispiel in Form von drehbaren Sprüharmen oder ortsfesten Düsensystemen. Die Bypass-Leitung endet dann beispielsweise an einer zusätzlichen Düse des Sprühsystems.The spray nozzle may be part of the spray system. This is usually arranged in three levels in the washing compartment, for example in the form of rotatable spray arms or fixed nozzle systems. The bypass line then ends, for example, at an additional nozzle of the spray system.
Bei einer vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung ist zumindest ein Teil des Behältnisses, beispielsweise eine Wand oder der Boden beweglich gelagert. Zum Ausspülen des Reinigungsmittels kann der bewegliche Teil aus einer Grundstellung in eine Zugabestellung bewegt werden. In der Grundstellung ist das Behältnis gegenüber dem Spülraum geschlossen, so dass das Reinigungsmittel vor dem Kontakt mit der Spülflotte geschützt ist. In der Zugabestellung ist das Behältnis dann in Richtung Spülraum offen, damit die Spülflotte das Reinigungsmittel in den Spülraum ausspülen kann. Der bewegliche Teil kann beim Öffnen des Behältnisses ähnlich einem Schalter den Ausspülvorgang einleiten und beim Schließen des Behältnisses diesen wieder beenden. Damit kann immer genau so viel Spülflotte dem Reinigungsmittel zudosiert werden, wie zu dessen Auflösung und Ausspülung notwendig ist.In an advantageous embodiment of the device according to the invention at least a part of the container, for example a wall or the bottom is movably mounted. For rinsing out the cleaning agent, the movable part can be moved from a basic position to an additional position. In the basic position, the container is closed relative to the washing compartment so that the detergent is protected from contact with the washing liquor. In the supply position, the container is then open in the direction of the washing compartment, so that the washing solution can rinse the detergent into the washing compartment. The movable part can initiate the flushing process when opening the container similar to a switch and terminate this when closing the container. This means that it is always possible to add just as much rinsing liquor to the cleaning agent as is necessary for its dissolution and rinsing.
Das Sprühelement kann zum Beispiel eine Sprühdüse oder ein System aus mehreren Sprühdüsen sein. Beides kann fest oder beweglich im Spülraum angeordnet sein. Die erfindungsgemäße Geschirrspülmaschine verfolgt im Gegensatz zum Stand der Technik das Konzept, dass die zum Ausspülen des Reinigungsmittels aus dem Behältnis vorgesehenen Elemente während eines gesamten Spülprogramms genutzt werden können. Dadurch wird vermieden, dass die Spülflotte in den Leitungen über einen längeren Zeitraum stehen bleibt und Ablagerungen bilden kann.The spray element may be, for example, a spray nozzle or a system of multiple spray nozzles. Both can be arranged fixed or movable in the washing compartment. In contrast to the prior art, the dishwasher according to the invention pursues the concept that the elements provided for rinsing out the cleaning agent from the container can be used during an entire washing program. This avoids that the rinsing liquor stops in the lines over a longer period of time and can form deposits.
Das schwenkbare Behältnis kann als Ganzes beispielsweise in einem zum Spülraum hin offenen Gehäuse beweglich angeordnet sein. In der Grundstellung schließt eineThe pivotable container can be arranged as a whole, for example, in a housing open to the washing compartment to move. In the basic position closes one
Seitenwand das becher- oder wannenförmige Behältnis in Richtung Spülraum bündig mit der Wand des Spülraumes oder dem Gehäuse ab. Das Behältnis ist in der Grundstellung bereits mit Reinigungsmittel befüllt. In dieser Stellung verhindert die zum Spülraum weisende Seitenwand des Behältnisses das Eindringen von Spülflotte in das Gehäuse. Auf einen zusätzlichen Deckel zum Schutz des Reinigungsmittels kann somit verzichtet werden. Ein Verklumpen beispielsweise eines pulverförmigen Reinigungsmittels verbunden mit einer Behinderung des Ausspülvorgangs oder eine vorzeitige Entfaltung der Reinigungsmittelwirkung kann damit verhindert werden.Side wall of the cup or trough-shaped container in the direction of flushing flush with the wall of the washing compartment or the housing. The container is already filled in the basic position with detergent. In this position, the side wall of the container facing the washing compartment prevents the penetration of washing liquor into the housing. An additional cover for the protection of the cleaning agent can thus be dispensed with. Clogging, for example, of a powdered cleaning agent associated with a hindrance of the rinsing process or premature unfolding of the cleaning agent effect can thus be prevented.
Bei der Erfindung ist das gesamte Behältnis von der Grundstellung in die Zugabestellung schwenkbar. Das Behältnis kann dazu entlang einer gekrümmten Bahn verschiebbar angeordnet oder drehbar gelagert sein. Diese Form der Lagerung ist einfach und kostengünstig herstellbar.In the invention, the entire container from the basic position in the addition position is pivotable. For this purpose, the container can be displaceably arranged or rotatably supported along a curved path. This form of storage is easy and inexpensive to produce.
Die drehbewegliche Verbindung des Behältnisses mit dem Gehäuse kann beispielsweise in Form von zwei Drehlagerstellen links und rechts des Behältnisbodens nahe der Spülraumwand ausgeführt sein, bei der zwei am Behältnis angeordnete Zapfen in entsprechende Ausnehmungen des Gehäuses eingreifen. Diese Form der Lagerung ermöglicht das Verschwenken des Behältnisses aus dem Gehäuse heraus in Richtung Spülraum bis in eine Befüllstellung. In der Befüllstellung ist der Innenraum des Behältnisses von der Seite des Spülraums aus zugänglich. In dieser Stellung kann das Behältnis dann beispielsweise von einem Benutzer manuell mit Reinigungsmittel befüllt werden. Die Begrenzung der Schwenkbewegung des Behältnisses in Richtung Spülraum kann durch Anschläge erfolgen, die am Behältnis und/oder am Gehäuse angeordnet sind.The rotatable connection of the container with the housing can be carried out, for example, in the form of two pivot points left and right of the container bottom near the Spülraumwand in which two pins arranged on the container engage in corresponding recesses of the housing. This form of storage allows the pivoting of the container out of the housing in the direction of Spülraum to a filling position. In the filling position, the interior of the container is accessible from the side of the washing compartment. In this position, the container can then be filled manually, for example by a user with detergent. The limitation of the pivoting movement of the container in the direction of the washing compartment can be effected by stops which are arranged on the container and / or on the housing.
Nachdem der Befüllvorgang abgeschlossen ist, muss das Behältnis wieder zurück in die Grundstellung geschwenkt und in dieser fixiert werden. Dazu können am Behältnis Rastmittel angeordnet sein, die mit Gegenrastmitteln am Gehäuse zur Verrastung des Behältnisses mit dem Gehäuse in der Grundstellung zusammenwirken. Die Bewegung des Behältnisses von der Befüllstellung in die Grundstellung sowie dessen dortige Fixierung kann - wie auch das Befüllen - automatisch bzw. programmablaufgesteuert oder von Hand durch einen Benutzer erfolgen.After the filling process is completed, the container must be swung back to the basic position and fixed in this. For this purpose, latching means can be arranged on the container, which interact with counter-latching means on the housing for latching the container with the housing in the basic position. The movement of the container from the filling position to the basic position and the local fixation can - as well as the filling - automatically or programmatically controlled or done manually by a user.
Grundsätzlich können alle Bewegungen des Behältnisses auch von einem Aktuator, beispielsweise in Form eines Motors, einer Spule oder eines Bimetalls, bewirkt werden. Das Bimetall kann zum Beispiel temperaturabhängig die Bewegung des Behältnisses veranlassen oder bewirken. Dabei handelt es sich um eine rein mechanische Steuerung. Bei Einsatz eines Motors kann dieser von einer Steuerungseinrichtung zum Beispiel programmablaufabhängig angesteuert werden, um dann die Bewegung des Behältnisses zu bewirken.In principle, all movements of the container can also be effected by an actuator, for example in the form of a motor, a coil or a bimetal. The bimetal can for example cause or effect the movement of the container depending on the temperature. This is a purely mechanical control. When using a motor, this can be controlled by a control device, for example, program sequence-dependent, to then cause the movement of the container.
Grundsätzlich kann die Zufuhr der Spülflotte auch in Abhängigkeit von der Bewegung des Behältnisses zwischen der Grundstellung und der Zugabestellung erfolgen. Die Position des Behältnisses in der Zugabestellung entspricht dabei der der Befüllstellung. Nach einer weiteren vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung kann dafür in der Versorgungsleitung ein zweites Ventil zur Steuerung des Volumenstroms der Spülflotte angeordnet sein, das mit dem Behältnis in Wirkverbindung steht. Dazu kann die Bewegung des Ventilstellgliedes generell in Abhängigkeit von der Bewegung oder Stellung des Behältnisses bewirkt werden. So kann gewährleistet werden, dass immer nur so viel Spülflotte in das Behältnis gelangt, wie zum Ausspülen des Reinigungsmittels erforderlich ist.In principle, the supply of the rinsing liquor can also take place as a function of the movement of the container between the basic position and the delivery position. The position of the container in the supply position corresponds to that of the filling position. According to a further advantageous embodiment of the device according to the invention can be arranged in the supply line, a second valve for controlling the volume flow of the rinsing liquor, which is in operative connection with the container. For this purpose, the movement of the valve actuator can generally be effected in dependence on the movement or position of the container. Thus, it can be ensured that only as much rinse liquor gets into the container, as is required for rinsing the detergent.
In einer einfachen Ausführungsform der Erfindung kann das zweite Ventil zum Beispiel in der Grundstellung des Behältnisses geschlossen und in der Zugabestellung des Behältnisses offen sein. Damit ist sichergestellt, dass nur dann Spülflotte in das Behältnis gelangt, wenn es in Richtung Spülraum geöffnet ist. Das kann beispielsweise mit einem am Behältnis angeordneten Stellelement realisiert werden, das in der Zugabestellung mit dem zweiten Ventil in Kontakt steht und dieses dann vollständig öffnet. Bei der Bewegung des Behältnisses von der Zugabestellung in die Grundstellung wird der Kontakt zwischen dem Stellelement und dem Ventil wieder unterbrochen, und das Ventil wird geschlossen. Anstelle eines mechanischen Stellelements kann auch ein Sensor zur Anwendung kommen, der die jeweilige Stellung des Behältnisses berührungsfrei detektiert und dementsprechend das Öffnen und Schließen des zweiten Ventils mittels der Steuerungseinrichtung bewirkt. Das Öffnen und Schließen des Ventils kann beispielsweise durch elektrische Stellantriebe veranlasst werden.In a simple embodiment of the invention, the second valve may for example be closed in the basic position of the container and be open in the supply position of the container. This ensures that only rinse liquor enters the container when it is open towards the dishwasher. This can be realized, for example, with an actuator disposed on the container, which is in the addition position with the second valve in contact and then completely opens. Upon movement of the container from the supply position to the home position, the contact between the actuator and the valve is interrupted again, and the valve is closed. Instead of a mechanical adjusting element, a sensor may also be used which detects the respective position of the container without contact and accordingly causes the opening and closing of the second valve by means of the control device. The opening and closing of the valve can be caused for example by electric actuators.
Bei einer weiteren Ausführungsform der Erfindung kann das zweite Ventil korrespondierend zu der Schwenkbewegung des Behältnisses zwischen der Grundstellung und der Ausspülstellung geöffnet werden. Das bedeutet, dass auch zu jeder Schwenkstellung zwischen der Grundstellung und der Zugabestellung eine entsprechende Stellung des Ventilstellgliedes einstellbar ist. Für das zweite Ventil existieren somit nicht nur zwei diskrete sondern eine Anzahl von Einstellungen zwischen der Offenstellung und der Geschlossenstellung. Damit lässt sich die zur Auflösung bzw. Ausspülung einer bestimmten Reinigermenge erforderliche Menge an Spülflotte noch besser dosieren.In a further embodiment of the invention, the second valve can be opened corresponding to the pivotal movement of the container between the basic position and the Ausspülstellung. This means that a corresponding position of the valve actuator is adjustable for each pivot position between the basic position and the addition order. Thus, not only two discrete but a number of settings exist between the open position and the closed position for the second valve. This makes it possible to even better dose the amount of rinsing liquor required for dissolving or rinsing out a certain amount of rinsing agent.
Des Weiteren ist es von Vorteil, wenn zwischen der Ventilstellung des zweiten Ventils und der Schwenkstellung des Behältnisses eine Kopplung besteht. Die Kopplung kann mechanisch, elektrisch oder sensorisch sein. Eine mechanische Kopplung kann zum Beispiel in Form eines Gestänges oder eines Getriebes ausgeführt sein. Für eine elektrische Kopplung kann beispielsweise ein am Drehpunkt des Behältnisses oder Behältnisteils angeordnetes Potentiometer mit einem elektrischen Stellantrieb verbunden sein. Bei einer sensorischen Kopplung wird die Bewegung bzw. die Schwenkstellung des Behältnisses mittels eines oder mehrerer Sensoren erfasst. Diese sind beispielsweise über eine Steuerungseinheit mit dem Stellglied des Ventils verbunden. Durch die Kopplung ist es möglich, die zur Ausspülung des Reinigungsmittels erforderliche Menge an Spülflotte der jeweiligen Stellung des Behältnisses anzupassen. Auf diese Weise kann das Reinigungsmittel gleichmäßig ausgespült bzw. aufgelöst werden. Eine abrupte Ausspülung des gesamten Reinigungsmittels, das sich dann erst im Spülraum vollständig auflöst, kann so vermieden werden.Furthermore, it is advantageous if there is a coupling between the valve position of the second valve and the pivot position of the container. The coupling can be mechanical, electrical or sensory. A mechanical coupling can be designed, for example, in the form of a linkage or a gearbox. For an electrical coupling, for example, a potentiometer arranged at the pivot point of the container or container part can be connected to an electric actuator. In a sensory coupling, the movement or the pivoting position of the container is detected by means of one or more sensors. These are connected for example via a control unit with the actuator of the valve. The coupling makes it possible to adapt the amount of rinsing liquor required for rinsing the cleaning agent to the respective position of the container. In this way, the detergent can be evenly rinsed or dissolved. An abrupt flushing of the entire cleaning agent, which then dissolves completely in the washroom, can thus be avoided.
Anstelle eines ersten und zweiten Ventils kann auch nur ein Ventil vorgesehen sein, das die Funktionen beider Ventile miteinander vereint.Instead of a first and second valve, only one valve may be provided, which combines the functions of both valves together.

Zu Beginn eines Spülvorgangs wird eine bestimmte Menge an Frischwasser über ein in
Die Umwälzpumpe 22 saugt die Spülflotte über eine Öffnung 54 im Boden des Spülraumes 12 an, und fördert sie sowohl durch die Leitung 20 zum Sprühsystem 16 als auch durch die Leitung 24 zum ersten Ventil 26. Je nach Spülprogramm bzw. Programmablauf wird von einer Steuereinheit 56 das Öffnen oder Schließen der Anschlüsse 28 und 34 des ersten Ventils 26 bewirkt. Die Spülflotte kann dadurch wahlweise durch die Leitung 32 und die Sprühdüse 30 in das Behältnis 46 der Zugabevorrichtung 14 und/oder durch die Leitung 36 und die Sprühdüse 38 in den Spülraum 12 gefördert werden. Weil die Leitung 32 nach der Reinigungsmittelzugabe vollständig deaktiviert wird, ist deren Länge so kurz wie möglich, um Ablagerungen durch die Spülflotte zu vermeiden. Zu diesem Zweck kann das Ventil 26 - abweichend von der Darstellung gemäß
Während der Reinigungsmittelzugabe wird dem Reinigungsmittel, das sich im Behältnis 46 befindet, über die Sprühdüse 30 Spülflotte zugeführt. Das Reinigungsmittel wird dabei in der Spülflotte gelöst und mit dieser durch die Ablauföffnung 48 und die Leitung 50 in den Spülraum 12 gespült.During the addition of detergent is the cleaning agent, which is located in the
Nachdem das Reinigungsmittel vollständig aus dem Behältnis 46 ausgespült wurde, wird der erste Anschluss 28 geschlossen, und der zweite Anschluss 34 geöffnet. Die Spülflotte wird dann nur noch durch die Leitung 36 zur Sprühdüse 38 gepumpt. Mit der Sprühdüse 38 werden gezielte Bereiche des Spülraumes 12 intensiv besprüht, die vom Sprühsystem 16 nicht oder nur unzureichend erreicht werden.After the cleaning agent has been completely flushed out of the
Die Steuereinheit 56 überträgt die zur Steuerung des Ventils 26 notwendigen Signale. Die Signalleitung 57 zwischen der Steuereinheit 56 und dem Ventil 26 ist durch eine unterbrochene Linie symbolisiert. Zur Erhöhung der Ausspülsicherheit kann nach Ablauf der für die Zugabe des Reinigungsmittels vorgesehenen Zeit der Anschluss 28 weiterhin offen gehalten werden, so dass eventuell im Behältnis 46 verbliebene Reste des Reinigungsmittels noch vollständig aus dem Behältnis 46 ausgespült werden können. Dazu kann der Anschluss 28 allein oder zusammen mit dem Anschluss 34 jeweils voll oder zum Teil geöffnet sein. Der Spülflottenstrom ist damit prozentual auf die Anschlüsse 28 und 34 aufteilbar, und somit immer in den Leitungen 24 sowie 32 und/oder 36 in Bewegung. Länger stehende Spülflotte und die damit verbundene Gefahr der Bildung von Ablagerungen in den Leitungen 24, 32 und 36 wird so vermieden.The
Im Unterschied zu
Bei dem Sensor handelt es sich um einen Drehlagensensor, der der Steuereinheit 56 ein Signal übermittelt, das der jeweiligen Schwenkposition des Bodens 42 zugeordnet ist. Die Steuereinheit 56 ermittelt eine korrespondierende Ventilstellung, und sendet ein entsprechendes Signal an das Stellglied des zweiten Ventils 27. So kann das zweite Ventil 27 im einfachsten Fall bei geschlossenem Boden 42 geschlossen, und bei geöffnetem Boden 42 geöffnet werden. Die Steuerung des zweiten Ventils 27 kann auch über den gesamten Öffnungsweg bzw. Schwenkbereich des Bodens 42 erfolgen. Das zweite Ventil 27 weist dann nicht nur zwei diskrete Ventilstellungen wie "Offen" und "Geschlossen" auf, sondern eine Vielzahl von Stellungen dazwischen. Der Volumenstrom der Spülflotte ist dann über den gesamten Schwenkbereich des Bodens 42 mittels des Ventilstellglieds einstellbar. Mit Beginn der Öffnung des Bodens 42 wird der Sprühdüse 30 dann bereits eine geringe Menge an Spülflotte zugeführt. Öffnet sich der Boden 42 weiter, nimmt auch der Volumenstrom der Spülflotte zu. Bei vollständig geöffnetem Boden 42 ist dann auch das zweite Ventil 27 vollständig geöffnet. Die dem Behältnis 46 zugeführte Menge an Spülflotte entspricht dabei immer gerade der Menge, die auch über den geöffneten Boden 42 aus dem Behältnis 46 in den Spülraum 12 ablaufen kann.The sensor is a rotational position sensor, which transmits to the control unit 56 a signal which is associated with the respective pivoting position of the

Die Zugabevorrichtung 14 ist in eine Aussparung der Wand 13 des Spülraumes 12 eingesetzt. Sie weist ein in Richtung des Spülraumes 12 offenes Gehäuse 17 auf. In diesem ist das Behältnis 47 drehbar gelagert. Die in Richtung Spülraum 12 weisende Öffnung des Gehäuses 17 wird von einer Seitenwand 41 des Behältnisses 47 vollständig und flüssigkeitsdicht abgedeckt. Das Reinigungsmittel im Behältnis 47 ist so vor einem Kontakt mit der Spülflotte noch vor der Reinigungsmittelzugabe geschützt.The adding
Die dabei ausgeführte Bewegung des Behältnisses 47 ist eine Dreh- bzw. Schwenkbewegung um eine Drehachse 58 herum, die durch den Pfeil B in
Das Behältnis 47 verbleibt bis zum Programmende in der Zugabestellung, so dass die Spülflotte aus der Sprühdüse 30 eventuell im Behältnis 47 verbliebene Reinigungsmittelreste vollständig ausspülen kann. Da die Zugabestellung gleich der Befüllstellung ist, kann das Behältnis 47 nach Ablauf des Spülprogramms in dieser Stellung verbleiben, bis es für ein weiteres Spülprogramm erneut mit Reinigungsmittel befüllt und wieder zurück in die Grundstellung verbracht wird.The

Es wird abschließend noch einmal daraufhin gewiesen, dass es sich bei den vorhergehenden, detailliert beschriebenen, Zugabevorrichtungen 14 um Ausführungsbeispiele handelt, die vom Fachmann in verschiedenster Weise modifiziert werden können, ohne den Bereich der Erfindung zu verlassen. Insbesondere können auch die konkreten Ausgestaltungen der Behältnisse 46 und 47 sowie die Anordnung und Ausführung der Ventile 26 und 27 in anderer Form als in der hier beschriebenen erfolgen. Es wird der Vollständigkeit halber außerdem darauf hingewiesen, dass die Verwendung der unbestimmten Artikel "ein" beziehungsweise "eine" nicht ausschließt, dass die betreffenden Merkmale auch mehrfach vorhanden sein können.Finally, it is once again pointed out that the preceding, described in detail, adding
