- the majority of household dishwashers currently in use has an adding device for receiving one or more cleaning agents which are added to the washing liquor during the course of a washing cycle for cleaning the items to be sorted in the dishwasher.
- the detergent stored in the adding device is completely discharged into the washing compartment during the rinsing cycle and mixed with the rinsing water circulated therein.
- the addition device is sized in size so that just the required amount of detergent for a rinse cycle can be filled. The user of the dishwasher is therefore forced to fill in the adding device the amount of detergent required for the rinse cycle at the beginning of each rinse cycle. This handling is inconvenient for the user of the dishwasher.
- such dishwashers have the problem that the amount of cleaning agent introduced into the adding device may vary from user to user, but also from one rinse to another.
- an incorrectly metered amount of cleaning agent can lead to unsatisfactory scavenging results if the cleaning agents have been dispensed too low and, on the other hand, a waste of cleaning agents and thus environmental pollution if too large an amount of cleaning agent has been dispensed.
- Addition devices which add the amount of cleaning agents stored therein at once to the rinsing liquor still do not permit the implementation of more complex rinsing programs. Thus, it may be useful, for example, in certain situations, to meter in the detergent at different times of the wash liquor. Addition devices configured to receive a single detergent dose can not support such complex rinse cycles.
- the household dishwasher has the DE 10 2005 061 801 A1 a metering device for controlling the addition of adding substances, for.
- a storage insert for adding substances eg cleaning and / or rinsing substances
- the dosing device can be assigned an interface device for interaction with different storage inserts for different types of addition substances, for example tabs, powdery or liquid.
- the interface device is preferably arranged on the metering device.
- the cartridge according to the invention for use in a detergent dosing system of a water-conducting household appliance, in particular a domestic dishwasher, has at least one detergent dispenser with a receiving space for receiving at least one cartridge, wherein the cartridge having separate chambers for receiving at least one cleaning agent. It is provided according to the invention that the chambers are in communication with at least one openable and at least once again closable closure. Since the cartridge only has to be opened once when it is inserted into a detergent dosing system and only has to be closed once when it is removed from a detergent system, it is preferably provided that the closure is designed for a single opening and a one-time closure.
- the closure for the automatic opening and closing during insertion or removal of the cartridge is formed in a a starsffendosiersystem.
- the closure ensures that the detergent stored in the cartridge can not leak unintentionally.
- the closure is opened at the moment in which the cartridge is inserted into the detergent dispenser of the detergent dosing system, so that a metered addition of the detergent to the rinsing liquor is possible during the further operation of the dishwasher.
- the openable closure may e.g. in the direction of gravity below, i. be arranged at the bottom of the cartridge when the cartridge is in installation position in the detergent dosing. As a result, the complete emptying of the cartridge is facilitated in its installed position, whereby no detergent remains unused in the cartridge.
- a constructively particularly simply constructed and inexpensive to produce cartridge results when the openable closure is formed by a membrane, a film or an elastomer. If the cartridge is e.g. made of a plastic, so the cartridge can be manufactured together with the openable closure by a two-component injection molding in one step.
- a cartridge according to the invention has at least one closure which, with the cartridge inserted into the detergent dosing system, is arranged corresponding to an opening means of the detergent dosing system, so that the openable closure is brought into an open position, in which the cleaning agent, in particular by the detergent dosing system, in one Rinse cycle is zugebbar.

- the cannula is stationary in the detergent dosing system. In this way, cleaning agent can be introduced into the detergent dosing system via the cannula during a rinsing cycle and metered into the rinsing liquor by the latter.
- the opening caused by the cannula closes due to the elastic properties of the openable closure, that an escape of possibly remaining residues of cleaning agent is prevented.
- This is provided with the simplest means an at least once again closable closure.
- the number of openable closures of the cartridge corresponds to the number of cleaning agents stored in the cartridge or to a number of chambers receiving the cleaning agents.
- the at least one cleaning agent is stored in respective chambers of the cartridge, further comprising a venting chamber operatively connected to the chambers.
- the storage of different cleaning agents in different chambers has the advantage that in a certain section of a rinsing cycle only that cleaning agent needs to be added, which is actually necessary for this rinsing section. Of course, it is possible that during a certain portion of a rinsing cycle, several of the cleaning agents are added simultaneously. Furthermore, it is possible to arrange a plurality of cleaning agents in a common chamber of the cartridge.
- the ventilation chamber ensures that in the respective, detergent receiving chambers with increasing emptying no negative pressure can occur, which would be a detrimental to a dosing of detergent in the wash liquor.
- the ventilation chamber is in operative connection via ventilation channels, which are provided in a common cover closing off the individual chambers, with which the chambers receiving the cleaning agent are operatively connected. If the cartridge is arranged in the detergent dosing system, the lid is arranged in the direction of gravity at the top. This ensures that with increasing emptying of the respective chambers of the cartridge air can flow into the chambers and the leakage or metering of the respective cleaning agent is simple and precise vorappelbar.
- the cartridge may further comprise at least one conveying device with which at least one cleaning agent, in particular via the detergent dosing system, for example, in the washing compartment of the dishwasher is conveyed.

- the major axis be longer than minor axes of the housing with one of the above basic shape of the cartridge, e.g. by a factor of at least 1.5.
- the base body may preferably have an extension along a first minor axis, e.g. along the height, and an extension along a second minor axis, e.g. along the depth, the extent along the first minor axis being substantially longer than the extent along the second minor axis, e.g. by a factor of 5 to 10, preferably 5.
- a particularly good handling of the cartridge and a suitable volume of respective cleaning agents arise when the housing of the cartridge has a quarry-shaped basic shape with a depth of about 25 mm, a width of about 200 mm and a Height of about 125 mm.
- the preferred total number z of rinsing cycles between 20 and 40, preferably 30, rinsing cycles can be realized with such dimensions.
- the chambers of the cartridge along the main axis are arranged side by side. That is, in a cartridge having a square basic shape and extending in the direction of the main axis, the division into chambers leads to chamber dimensions in which the dimension of a chamber is the number of chambers corresponding proportion of the width, while for all chamber an equal depth and Height is given.
- At least one of the chambers comprises at least one of the following ingredients: alkali carriers, e.g. Caustic, complexing and dispersing agents; e.g. polymers; Enzymes such as amylase, protease or lipase; Bleaching agent, e.g. hydrogen peroxide; Bleach activator, and surfactants, such as e.g. nonionic surfactants.

Abstract
Description
Die Erfindung betrifft eine Kartusche nach dem Oberbegriff des Patentanspruchs 1. Ferner betrifft die Erfindung ein wasserführendes Haushaltsgerät mit einem Reinigungsmitteldosiersystem.The invention relates to a cartridge according to the preamble of claim 1. Furthermore, the invention relates to a water-conducting household appliance with a Reinigungsmitteldosiersystem.
Die Mehrzahl der derzeit bspw. im Einsatz befindlichen Haushalts-Geschirrspülmaschinen besitzt eine Zugabevorrichtung zur Aufnahme eines oder mehrerer Reinigungsmittel, welche im Verlauf eines Spülzyklus der Spülflotte zum Reinigen des in der Geschirrspülmaschine einsortierten Spülguts zugegeben werden. Üblicherweise wird das in der Zugabevorrichtung bevorratete Reinigungsmittel während des Spülzyklus vollständig in den Spülraum abgegeben und der darin umgewälzten Spülflotte beigemischt. Die Zugabevorrichtung ist von ihrer Größe her derart bemessen, dass gerade die für einen Spülzyklus benötigte Menge an Reinigungsmitteln eingefüllt werden kann. Der Benutzer der Geschirrspülmaschine ist deshalb gezwungen, zum Beginn jedes Spülzyklus die für den Spülzyklus benötigte Menge an Reinigungsmittel in die Zugabevorrichtung einzufüllen. Diese Handhabung ist für den Benutzer der Geschirrspülmaschine unbequem. Darüber hinaus besteht bei derartigen Geschirrspülmaschinen das Problem, dass die Menge an in die Zugabevorrichtung eingefüllten Reinigungsmitteln von Benutzer zu Benutzer, aber auch von Spülgang zu Spülgang variieren kann. Eine nicht korrekt dosierte Menge an Reinigungsmittel kann einerseits zu unbefriedigenden Spülergebnissen führen, wenn die Reinigungsmittel zu gering dosiert wurden, und andererseits eine Verschwendung an Reinigungsmitteln und damit eine Belastung der Umwelt zur Folge haben, wenn eine zu große Menge an Reinigungsmitteln dosiert wurde.The majority of household dishwashers currently in use, for example, has an adding device for receiving one or more cleaning agents which are added to the washing liquor during the course of a washing cycle for cleaning the items to be sorted in the dishwasher. Usually, the detergent stored in the adding device is completely discharged into the washing compartment during the rinsing cycle and mixed with the rinsing water circulated therein. The addition device is sized in size so that just the required amount of detergent for a rinse cycle can be filled. The user of the dishwasher is therefore forced to fill in the adding device the amount of detergent required for the rinse cycle at the beginning of each rinse cycle. This handling is inconvenient for the user of the dishwasher. Moreover, such dishwashers have the problem that the amount of cleaning agent introduced into the adding device may vary from user to user, but also from one rinse to another. On the one hand, an incorrectly metered amount of cleaning agent can lead to unsatisfactory scavenging results if the cleaning agents have been dispensed too low and, on the other hand, a waste of cleaning agents and thus environmental pollution if too large an amount of cleaning agent has been dispensed.
Zugabevorrichtungen, welche die darin gespeicherte Menge an Reinigungsmitteln auf einmal der Spülflotte zusetzen, lassen weiterhin die Durchführung komplexerer Spülprogramme nicht zu. So kann es beispielsweise in bestimmten Situationen sinnvoll sein, das Reinigungsmittel zu verschiedenen Zeitpunkten der Spülflotte zuzudosieren. Zugabevorrichtungen, welche zur Aufnahme einer einzigen Reinigungsmittel-Dosis ausgebildet sind, können derartige komplexe Spülzyklen nicht unterstützen.Addition devices which add the amount of cleaning agents stored therein at once to the rinsing liquor still do not permit the implementation of more complex rinsing programs. Thus, it may be useful, for example, in certain situations, to meter in the detergent at different times of the wash liquor. Addition devices configured to receive a single detergent dose can not support such complex rinse cycles.
Z.B. weist die Haushalts-Geschirrspülmaschine der
Der Einsatz eines Behälters oder einer Kartusche in einem Reinigungsmitteldosiersystem bringt das Problem mit sich, dass bei der Entnahme des Behälters oder der Kartusche aus dem Reinigungsmitteldosiersystem eventuell noch darin befindliche Reinigungsmittelreste austreten können. Das Austreten der Reinigungsmittel könnte - je nach darin befindlichen Substanzen - zu einer Gefährdung der Gesundheit der Personen führen, wenn diese in Kontakt mit dem Reinigungsmittel geraten.The use of a container or a cartridge in a detergent dosing system involves the problem that during removal of the container or the cartridge from the detergent dosing system, any remaining cleaning agent may escape. Depending on the substances contained in them, leakage of the cleaning agents could endanger the health of the persons in contact with the cleaning agent.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Kartusche und ein wasserführendes Haushaltsgerät anzugeben, welche den oben genannten Nachteil nicht aufweisen. Ferner ist es Aufgabe der Erfindung, ein Reinigungsmitteldosiersystem anzugeben.It is therefore an object of the present invention to provide a cartridge and a water-conducting household appliance, which do not have the above-mentioned disadvantage. It is a further object of the invention to specify a detergent dosing system.
Diese Aufgabe wird durch eine erfindungsgemäße Kartusche mit den Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den abhängigen Patentansprüchen.This object is achieved by a cartridge according to the invention with the features of claim 1. Advantageous embodiments will be apparent from the dependent claims.
Die erfindungsgemäße Kartusche zum Einsatz in einem Reinigungsmitteldosiersystem eines wasserführenden Haushaltsgeräts, insbesondere einer Haushalts-Geschirrspülmaschine, weist wenigstens einen Reinigungsmittelspender mit einem Aufnahmeraum zur Aufnahme wenigstens einer Kartusche auf, wobei die Kartusche getrennte Kammern zur Aufnahme wenigstens je eines Reinigungsmittels aufweist. Dabei ist erfindungsgemäß vorgesehen, dass die Kammern wenigstens mit zumindest einem öffenbaren und zumindest einmal wieder verschließbaren Verschluss in Verbindung stehen. Da die Kartusche nur einmal beim Einsetzten in ein Reinigungsmitteldosiersystem geöffnet und nur einmal beim Herausnehmen aus ein Reinigungsmittelsystem verschlossen werden muss ist vorzugsweise ist vorgesehen, dass der Verschluss zum einmaligen Öffnen und zum einmaligen Verschließen ausgebildet ist.The cartridge according to the invention for use in a detergent dosing system of a water-conducting household appliance, in particular a domestic dishwasher, has at least one detergent dispenser with a receiving space for receiving at least one cartridge, wherein the cartridge having separate chambers for receiving at least one cleaning agent. It is provided according to the invention that the chambers are in communication with at least one openable and at least once again closable closure. Since the cartridge only has to be opened once when it is inserted into a detergent dosing system and only has to be closed once when it is removed from a detergent system, it is preferably provided that the closure is designed for a single opening and a one-time closure.
Dabei ist vorzugsweise vorgesehen, dass der Verschluss zum selbsttätigen Öffnen und Verschließen beim Einsetzen bzw. Herausnehmen der Kartusche in ein Reinigungsmitteldosiersystem ausgebildet ist. Der Verschluss dient während der Lagerung und des Transports dazu, dass das in der Kartusche bevorratete Reinigungsmittel nicht unbeabsichtigt auslaufen kann. Das Öffnen des Verschlusses erfolgt in dem Moment, in dem die Kartusche in den Reinigungsmittelspender des Reinigungsmitteldosiersystems eingesetzt wird, so dass während des weiteren Betriebs der Geschirrspülmaschine eine Zudosierung des Reinigungsmittels zur Spülflotte möglich ist. Der öffenbare Verschluss kann z.B. in Schwerkraftrichtung unten, d.h. am Boden der Kartusche angeordnet sein, wenn die Kartusche sich in Einbaulage in dem Reinigungsmitteldosiersystem befindet. Hierdurch wird das vollständige Entleeren der Kartusche in ihrer Einbaulage erleichtert, wodurch kein Reinigungsmittel in der Kartusche ungenutzt verbleibt. Es kann gewährleistet werden, dass aus der Kartusche nach der Entnahme aus dem Reinigungsmitteldosiersystem kein Reinigungsmittel austreten kann. Eine konstruktiv besonders einfach aufgebaute und kostengünstig herzustellende Kartusche ergibt sich dann, wenn der öffenbare Verschluss durch eine Membran, eine Folie oder einen Elastomer gebildet ist. Ist die Kartusche z.B. aus einem Kunststoff gefertigt, so kann die Kartusche zusammen mit dem öffenbaren Verschluss durch ein 2Komponenten-Spritzverfahren in einem Schritt gefertigt werden.It is preferably provided that the closure for the automatic opening and closing during insertion or removal of the cartridge is formed in a Reinigungsmitteldosiersystem. During storage and transport, the closure ensures that the detergent stored in the cartridge can not leak unintentionally. The closure is opened at the moment in which the cartridge is inserted into the detergent dispenser of the detergent dosing system, so that a metered addition of the detergent to the rinsing liquor is possible during the further operation of the dishwasher. The openable closure may e.g. in the direction of gravity below, i. be arranged at the bottom of the cartridge when the cartridge is in installation position in the detergent dosing. As a result, the complete emptying of the cartridge is facilitated in its installed position, whereby no detergent remains unused in the cartridge. It can be ensured that no detergent can escape from the cartridge after removal from the detergent dosing system. A constructively particularly simply constructed and inexpensive to produce cartridge results when the openable closure is formed by a membrane, a film or an elastomer. If the cartridge is e.g. made of a plastic, so the cartridge can be manufactured together with the openable closure by a two-component injection molding in one step.
Vorzugsweise wiest eine erfindungsgemäße Kartusche wenigstens einen Verschluss auf, welcher bei eingesetzter Kartusche in das Reinigungsmitteldosiersystem korrespondierend zu einem Öffnungsmittel des Reinigungsmitteldosiersystems angeordnet ist, so dass der öffenbare Verschluss in eine geöffnete Position gebracht ist, in welcher das Reinigungsmittel, insbesondere durch das Reinigungsmitteldosiersystem, in einem Spülzyklus zugebbar ist.Preferably, a cartridge according to the invention has at least one closure which, with the cartridge inserted into the detergent dosing system, is arranged corresponding to an opening means of the detergent dosing system, so that the openable closure is brought into an open position, in which the cleaning agent, in particular by the detergent dosing system, in one Rinse cycle is zugebbar.
Die erfindungsgemäße Kartusche ist mit einem öffenbaren Verschluss versehen, der beim Einsetzen in das Reinigungsmitteldosiersystem selbsttätig öffenbar und beim Entnehmen der Kartusche aus dem Reinigungsmitteldosiersystem selbsttätig schließbar ist. Der öffenbare Verschluss ist beim Einsetzen der Kartusche in das Reinigungsmitteldosiersystem korrespondierend zu einer Kanüle des Reinigungsmitteldosiersystems angeordnet, so dass der öffenbare Verschluss von dieser durchdrungen wird. Die Kanüle ist dabei ortsfest in dem Reinigungsmitteldosiersystem vorgesehen. Damit kann über die Kanüle Reinigungsmittel in das Reinigungsmitteldosiersystem während eines Spülzyklus gelangen und von diesem zur Spülflotte zudosiert werden. Wird andererseits die Kartusche wieder aus dem Reinigungsmitteldosiersystem entnommen, so verschließt sich aufgrund der elastischen Eigenschaften des öffenbaren Verschlusses die durch die Kanüle hervorgerufene Öffnung, dass ein Austritt eventuell noch darin befindlicher Reste an Reinigungsmittel verhindert ist. Hiermit ist mit einfachsten Mitteln ein zumindest einmalig wieder verschließbarer Verschluss bereitgestellt.The cartridge according to the invention is provided with an openable closure which can be opened automatically on insertion into the detergent dosing system and can be automatically closed when removing the cartridge from the detergent dosing system. The openable closure is arranged on insertion of the cartridge into the detergent dosing system corresponding to a cannula of the detergent dosing system, so that the openable closure is penetrated by the latter. The cannula is stationary in the detergent dosing system. In this way, cleaning agent can be introduced into the detergent dosing system via the cannula during a rinsing cycle and metered into the rinsing liquor by the latter. If, on the other hand, the cartridge is removed again from the detergent dosing system, then the opening caused by the cannula closes due to the elastic properties of the openable closure, that an escape of possibly remaining residues of cleaning agent is prevented. This is provided with the simplest means an at least once again closable closure.
Die Anzahl der öffenbaren Verschlüsse der Kartusche entspricht in einer Ausgestaltung der Anzahl der in der Kartusche bevorrateten Reinigungsmittel oder einer Anzahl an, die Reinigungsmittel aufnehmenden, Kammern.In one embodiment, the number of openable closures of the cartridge corresponds to the number of cleaning agents stored in the cartridge or to a number of chambers receiving the cleaning agents.
Das wenigstens eine Reinigungsmittel ist in jeweiligen Kammern der Kartusche bevorratet, wobei weiter eine Belüftungskammer vorgesehen ist, welche in operativer Verbindung mit den Kammern steht. Das Bevorraten unterschiedlicher Reinigungsmittel in unterschiedlichen Kammern weist den Vorteil auf, dass in einem bestimmten Abschnitt eines Spülzyklus lediglich dasjenige Reinigungsmittel zudosiert werden zu braucht, welches für diesen Spülabschnitt tatsächlich notwendig ist. Selbstverständlich ist es dabei möglich, dass während eines bestimmten Abschnitts eines Spülzyklus auch mehrere der Reinigungsmittel gleichzeitig zudosiert werden. Ferner ist es möglich, mehrere Reinigungsmittel in einer gemeinsamen Kammer der Kartusche anzuordnen. Die Belüftungskammer trägt dafür Sorge, dass in den jeweiligen, Reinigungsmittel aufnehmenden, Kammern mit zunehmender Entleerung kein Unterdruck entstehen kann, welcher einem Zudosieren von Reinigungsmittel in die Spülflotte hinderlich wäre.The at least one cleaning agent is stored in respective chambers of the cartridge, further comprising a venting chamber operatively connected to the chambers. The storage of different cleaning agents in different chambers has the advantage that in a certain section of a rinsing cycle only that cleaning agent needs to be added, which is actually necessary for this rinsing section. Of course, it is possible that during a certain portion of a rinsing cycle, several of the cleaning agents are added simultaneously. Furthermore, it is possible to arrange a plurality of cleaning agents in a common chamber of the cartridge. The ventilation chamber ensures that in the respective, detergent receiving chambers with increasing emptying no negative pressure can occur, which would be a detrimental to a dosing of detergent in the wash liquor.
Dabei ist insbesondere vorgesehen, dass die Belüftungskammer über Belüftungskanäle, die in einem gemeinsamen, die einzelnen Kammern abschließenden, Deckel vorgesehen sind, mit den die Reinigungsmittel aufnehmenden Kammern in operativer Verbindung steht. Ist die Kartusche in dem Reinigungsmitteldosiersystem angeordnet, so ist der Deckel in Schwerkraftrichtung oben angeordnet. Damit ist gewährleistet, dass mit zunehmender Entleerung der jeweiligen Kammern der Kartusche Luft in die Kammern nachströmen kann und das Auslaufen bzw. Zudosieren der jeweiligen Reinigungsmittel einfach und präzise vornehmbar ist.In this case, provision is made in particular for the ventilation chamber to be in operative connection via ventilation channels, which are provided in a common cover closing off the individual chambers, with which the chambers receiving the cleaning agent are operatively connected. If the cartridge is arranged in the detergent dosing system, the lid is arranged in the direction of gravity at the top. This ensures that with increasing emptying of the respective chambers of the cartridge air can flow into the chambers and the leakage or metering of the respective cleaning agent is simple and precise vornehmbar.
Die Kartusche kann ferner wenigstens eine Fördereinrichtung aufweisen, mit der wenigstens ein Reinigungsmittel, insbesondere über das Reinigungsmitteldosiersystem, bspw. in den Spülraum der Geschirrspülmaschine förderbar ist. Die Fördereinrichtung kann z.B. in der Form einer Pumpe ausgebildet sein. Die Förderung der Reinigungsmittel in den Spülraum der Geschirrspülmaschine kann jedoch auch unter Ausnutzung der Schwerkraft erfolgen, wobei die Fördereinrichtung in diesem Fall die Funktion eines Ventils ausbildet, welches das Auslaufen von Spülmitteln aus den jeweiligen Kammern der Kartusche erlaubt oder unterbindet. Insbesondere kann dabei eine der Anzahl der Reinigungsmittel entsprechende Anzahl an Fördereinrichtungen vorgesehen sein.The cartridge may further comprise at least one conveying device with which at least one cleaning agent, in particular via the detergent dosing system, for example, in the washing compartment of the dishwasher is conveyed. The conveyor may e.g. be formed in the form of a pump. However, the promotion of the cleaning agent in the washing compartment of the dishwasher can also take place by utilizing gravity, the conveyor in this case forms the function of a valve which allows or prevents the leakage of detergent from the respective chambers of the cartridge. In particular, it is possible to provide a number of conveyors corresponding to the number of cleaning agents.
Um ein falsches Einlegen der Kartusche in den Reinigungsmittelspender zu unterbinden, verfügt das Gehäuse der Kartusche über eine mechanische Kodierung, gebildet bspw. durch Vorsprünge oder Führungen. Die Kodierung ist derart ausgestaltet, dass sich die Kartusche lediglich auf eine einzige Weise, die vorbestimmte Weise, in den Reinigungsmittelspender einsetzen lässt. Auf diese Weise ist sichergestellt, dass der öffenbare Verschluss korrespondierend zu dem Öffnungsmittel des Reinigungsmitteldosiersystems anordnenbar ist.To prevent incorrect insertion of the cartridge in the detergent dispenser, the housing of the cartridge has a mechanical coding, formed for example. By projections or guides. The coding is designed such that the cartridge can be inserted into the detergent dispenser in only one way, the predetermined way. In this way it is ensured that the openable closure can be arranged corresponding to the opening means of the detergent dosing system.
Die Kartusche kann jede geeignete Form aufweisen. Vorzugsweise ist jedoch vorgesehen, dass das Gehäuse der Kartusche eine Längserstreckung entlang einer Hauptachse aufweist. Hierbei kann es sich z.B. um einen quarderförmigen Grundkörper mit einer Längsachse, bspw. entlang der Breite, handeln, die wesentlich länger als alle anderen Achsen (entlang der Tiefe und der Höhe) ist. Es kann sich aber auch um einen kegel-, kegelstumpf-, zylinder-, pyramiden- oder pyramidenstumpfförmigen Grundkörper mit einer Hauptachse handeln.The cartridge may have any suitable shape. Preferably, however, it is provided that the housing of the cartridge has a longitudinal extent along a main axis. This may be, for example, a quarter-basic body with a longitudinal axis, for example. Along the width, which is much longer than all other axes (along the depth and height). But it may also be a cone, truncated cone, cylinder, pyramid or truncated pyramidal basic body with a major axis.
Dabei ist vorzugsweise, dass die Hauptachse länger als Nebenachsen des Gehäuses mit einer der oben genannten Grundform der Kartusche ist, z.B. um den Faktor mindestens 1,5. Ferner kann der Grundkörper vorzugsweise eine Erstreckung entlang einer ersten Nebenachsen aufweisen, z.B. entlang der Höhe, und eine Erstreckung entlang einer zweiten Nebenachse, z.B. entlang der Tiefe, aufweisen, wobei die Erstreckung entlang der erste Nebenachse wesentlich länger als die Erstreckung entlang der zweiten Nebenachse ist, z.B. um den Faktor 5 bis 10, vorzugsweise 5. Eine besonders gute Handhabung der Kartusche und ein zweckmäßiges Volumen jeweiliger Reinigungsmittel ergeben sich dann, wenn das Gehäuse der Kartusche eine quarderförmige Grundform mit eine Tiefe von etwa 25 mm, eine Breite von etwa 200 mm und eine Höhe von etwa 125 mm aufweist. Insbesondere lassen sich bei derartigen Abmaßen die bevorzugte Gesamtzahl z von Spülzyklen zwischen 20 und 40, bevorzugt 30, Spülzyklen realisieren.It is preferred that the major axis be longer than minor axes of the housing with one of the above basic shape of the cartridge, e.g. by a factor of at least 1.5. Furthermore, the base body may preferably have an extension along a first minor axis, e.g. along the height, and an extension along a second minor axis, e.g. along the depth, the extent along the first minor axis being substantially longer than the extent along the second minor axis, e.g. by a factor of 5 to 10, preferably 5. A particularly good handling of the cartridge and a suitable volume of respective cleaning agents arise when the housing of the cartridge has a quarry-shaped basic shape with a depth of about 25 mm, a width of about 200 mm and a Height of about 125 mm. In particular, the preferred total number z of rinsing cycles between 20 and 40, preferably 30, rinsing cycles can be realized with such dimensions.
In einer bevorzugten Weiterbildung ist vorgesehen, dass die Kammern der Kartusche entlang der Hauptachse nebeneinander angeordnet sind. D.h., dass bei einer Kartusche mit quarderförmiger Grundform und sich in Richtung der Breite erstreckender Hauptachse die Einteilung in Kammern zu Kammerabmessungen führt, bei der die Abmessung einer Kammer ein der Anzahl der Kammern entsprechender Anteil der Breite ist, während für aller Kammer eine gleich Tiefe und Höhe gegeben ist.In a preferred embodiment it is provided that the chambers of the cartridge along the main axis are arranged side by side. That is, in a cartridge having a square basic shape and extending in the direction of the main axis, the division into chambers leads to chamber dimensions in which the dimension of a chamber is the number of chambers corresponding proportion of the width, while for all chamber an equal depth and Height is given.
Schließlich ist vorzugsweise vorgesehen, dass wenigstens eine der Kammern wenigstens eine der folgenden Inhaltstoffe aufweist: Alkaliträger, z.B. Lauge, Komplexier- und Dispergierstoffe; z.B. Polymere; Enzyme wie Amylase, Protease oder Lipase; Bleichmittel, z.B. Wasserstoffperoxid; Bleichaktivator, und Tenside, wie z.B. nichtionische Tenside. Ferner kann zusätzlich eine biozidwirkende Flüssigkeit bevorratet werden. Insbesondere können Biozide gegen Bakterien (Bakterizide), gegen Pilze (Fungizide), gegen Keime (Mikrobizide), gegen Viren (Viruzide) und auch gegen Algen (Algizide) bevorratet werden, deren Zugabe unangenehme Geruchsentwicklungen durch z.B. Biofilmbildung während längerer Standzeiten zu unterbinden.Finally, it is preferably provided that at least one of the chambers comprises at least one of the following ingredients: alkali carriers, e.g. Caustic, complexing and dispersing agents; e.g. polymers; Enzymes such as amylase, protease or lipase; Bleaching agent, e.g. hydrogen peroxide; Bleach activator, and surfactants, such as e.g. nonionic surfactants. Furthermore, a biocidal fluid can be additionally stored. In particular, biocides can be stored against bacteria (bactericides), against fungi (fungicides), against germs (microbicides), against viruses (virucides) and also against algae (algicides), the addition of which can lead to unpleasant odor developments by e.g. Prevent biofilm formation during prolonged service life.
Die Erfindung betrifft auch ein wasserführendes Haushaltsgerät, insbesondere eine Haushalts-Geschirrspülmaschine, ein Reinigungsmitteldosiersystem aufweisend, wobei das Reinigungsmitteldosiersystem einen Reinigungsmittelspender mit wenigstens einem Aufnahmeraum zur Aufnahme wenigstens einer erfindungsgemäß ausgebildeten Kartusche aufweist.The invention also relates to a water-conducting household appliance, in particular a domestic dishwasher, a Reinigungsmitteldosiersystem comprising, wherein the detergent dosing a detergent dispenser with at least one Receiving space for receiving at least one inventively designed cartridge.
Eine vorteilhafte Weiterbildung der Erfindung umfasst ferner ein wasserführendes Haushaltsgerät, insbesondere eine Haushaltsgeschirrspülmaschine, mit einem Reinigungsmitteldosiersystem und ist dadurch gekennzeichnet, dass das Reinigungsmitteldosiersystem einen Reinigungsmittelspender mit wenigstens einem Aufnahmeraum zur Aufnahme wenigstens einer Kartusche mit wenigstens einem öffenbaren Verschluss aufweist und Öffnungsmittel derart angeordnet sind, dass bei wenigstens einer eingesetzten Kartusche der wenigstens eine Verschluss in eine geöffnete Position gebracht ist. Dabei kann das Reinigungsmitteldosiersystem angrenzend an einen Spülraum der Geschirrspülmaschine im Inneren der Geschirrspülmaschine ausgebildet sein. Der Reinigungsmittelspender weist einen Aufnahmeraum für wenigstens eine wenigstens ein Reinigungsmittel enthaltende Kartusche auf, wobei die bevorratete Menge an Reinigungsmittel größer als die für einen Spülzyklus benötige Menge ist. Dabei stellt das Reinigungsmitteldosiersystem genau die Menge an Reinigungsmittel bereit, die für einen Spülzyklus notwendig ist.An advantageous development of the invention further comprises a water-conducting household appliance, in particular a domestic dishwasher, with a detergent dosing system and is characterized in that the detergent dosing a detergent dispenser having at least one receiving space for receiving at least one cartridge having at least one openable closure and opening means are arranged such that in at least one inserted cartridge, the at least one closure is brought into an open position. In this case, the detergent dosing system can be formed adjacent to a washing compartment of the dishwasher in the interior of the dishwasher. The detergent dispenser has a receiving space for at least one cartridge containing at least one cleaning agent, wherein the stored amount of cleaning agent is greater than the amount required for a rinsing cycle. The detergent dosing system provides exactly the amount of detergent needed for a rinse cycle.
Das erfindungsgemäße Reinigungsmitteldosiersystem umfasst damit als Hauptkomponenten einen in der Geschirrspülmaschine ortsfest angeordneten Reinigungsmittelspender sowie wenigstens eine Reinigungsmittel enthaltende Kartusche.The detergent dosing system according to the invention thus comprises as main components a detergent dispenser stationarily arranged in the dishwasher and also a cartridge containing at least one detergent.
Das Öffnungsmittel des Reinigungsmitteldosiersystems übernimmt dabei die Aufgabe, den Zugang zu der Kartusche freizulegen, sobald diese in den Reinigungsmittelspender des Reinigungsmitteldosiersystems eingelegt wurde. Im Übrigen sind damit die gleichen Vorteile verbunden, wie sie vorstehend bereits erläutert wurden.The opening means of the detergent dosing system takes on the task of exposing the access to the cartridge as soon as it has been inserted into the detergent dispenser of Reinigungsmitteldosiersystems. Incidentally, the same advantages are associated with it, as already explained above.
Das Öffnungsmittel des erfindungsgemäßen Reinigungsmitteldosiersystems ist durch eine Kanüle gebildet, wobei der öffenbare Verschluss beim Einsetzen wenigstens einer Kartusche in das Reinigungsmitteldosiersystem korrespondierend zu der Kanüle angeordnet ist, so dass der Verschluss der wenigstens einen Kartusche von dieser durchdrungen wird. Es versteht sich von selbst, dass bei einer Mehrzahl an öffenbaren Verschlüssen eine entsprechende Anzahl an korrespondierend angeordneten Kanülen vorgesehen ist, welche jeweils ein Durchdringen des betreffenden Verschlusses bewirken. Unabhängig davon kann auch vorgesehen sein, dass einem öffenbaren Verschluss eine Mehrzahl an Öffnungsmitteln, insbesondere Kanülen, zugeordnet sind. Damit kann beispielsweise der Volumendurchfluss in einer bestimmten Zeit ohne besondere Ansteuerung beeinflusst werden.The opening means of the detergent dosing system according to the invention is formed by a cannula, wherein the openable closure is arranged upon insertion of at least one cartridge into the detergent dosing system corresponding to the cannula, so that the closure of the at least one cartridge is penetrated by the latter. It goes without saying that in the case of a plurality of openable closures, a corresponding number of correspondingly arranged cannulas is provided, which each cause a penetration of the respective closure. Regardless, it can also be provided that a plurality of opening means, in particular cannulas, are associated with an openable closure. Thus, for example, the volume flow can be influenced in a certain time without special control.
Um eine korrespondierende Lagerung der wenigstens einen Kartusche zu dem Öffnungsmittel des Reinigungsmittelspenders sicherstellen zu können, ist in dem Reinigungsmitteldosiersystem eine Haltevorrichtung zur Halterung und Lagefixierung der Kartusche umfasst. Die Haltevorrichtung ist in einer Ausführungsform durch eine Aufnahme an einem Deckel des Reinigungsmittelspenders gebildet, der zwischen einer Öffnungsposition und einer Verschlussposition bewegbar, insbesondere verschwenkbar, ist und den Aufnahmeraum in der Verschlussposition verschließt. Diese sorgt neben der bestimmungsgemäßen, lagerichtigen Halterung der Kartusche für ein erleichtertes Einsetzen und Austauschen einer leeren Kartusche. Die Aufnahme kann beispielsweise durch an dem Deckel L-förmig ausgebildete Haltelaschen gebildet sein, wobei sich jeweils erste Abschnitte der Haltelaschen in etwa senkrecht von einer Hauptfläche des Deckels weg erstrecken und an den, von der Hauptfläche abgewandten, Enden der ersten Abschnitte zu diesen in etwa senkrecht verlaufende zweite Abschnitte angeordnet sind, während von den ersten Abschnitten abgewandte Enden einander zugewandt sind.In order to ensure a corresponding mounting of the at least one cartridge to the opening means of the detergent dispenser, a holding device for holding and fixing the position of the cartridge is included in the detergent dosing system. The holding device is formed in one embodiment by a receptacle on a lid of the detergent dispenser, which is movable between an open position and a closed position, in particular pivotable, and closes the receiving space in the closed position. This ensures in addition to the proper, positionally correct mounting of the cartridge for easier insertion and replacement of an empty cartridge. The receptacle can be formed, for example, by holding lugs formed on the cover L-shaped, with first portions of the holding tabs extending approximately perpendicularly away from a main face of the lid and at the ends of the first portions facing away from the main face vertically extending second sections are arranged, while facing away from the first sections ends facing each other.
Das Reinigungsmitteldosiersystem kann ferner eine Positionierungsvorrichtung zur Positionierung der wenigstens einen Kartusche in dem Reinigungsmittelspender aufweisen, welche einen vorgegebenen Sitz der Kartusche in dem Reinigungsmitteldosiersystem erzwingt, wenn die Kartusche in dem Aufnahmeraum angeordnet ist. Durch die Vorrichtung zur Positionierung der wenigstens einen Kartusche kann sichergestellt werden, dass die bestimmungsgemäße korrespondierende Anordnung von öffenbaren Verschlüssen und Öffnungsmitteln des Reinigungsmittelspenders eingehalten wird. Damit ist das Zudosieren des Reinigungsmittels bestimmungsgemäß gewährleistet.The detergent dosing system may further comprise a positioning device for positioning the at least one cartridge in the detergent dispenser, which forces a predetermined seating of the cartridge in the detergent dosing system when the cartridge is disposed in the receiving space. By means of the device for positioning the at least one cartridge, it is possible to ensure that the intended arrangement of openable closures and opening means of the detergent dispenser is adhered to. This ensures the metered addition of the cleaning agent as intended.
In einer weiteren Ausführungsform ist vorgesehen, dass das Reinigungsmitteldosiersystem über zumindest einen, mit dem Spülraum in operativer Verbindung stehenden, Auslass verfügt, über den eine festgelegte Menge an Reinigungsmittel der Spülflotte während eines Spülzyklus zuführbar ist, wobei der zumindest eine Auslass an dem Reinigungsmittelspender vorgesehen ist. Es ist zweckmäßig, wenn der zumindest eine Auslass an dem Gehäuseabschnitt des Reinigungsmittelspenders vorgesehen ist, der in Schwerkraftrichtung unterhalb des Aufnahmeraums angeordnet ist. Dabei kann eine Anzahl an Auslässen vorgesehen sein, die der Anzahl der in der Kartusche bevorrateten Reinigungsmittel oder der Anzahl der die Reinigungsmittel aufnehmenden Kammern entspricht.In a further embodiment, it is provided that the detergent dosing system has at least one outlet, which is in operative connection with the rinsing chamber, via which a defined amount of cleaning agent can be fed to the rinsing liquor during a rinsing cycle, wherein the at least one outlet is provided on the detergent dispenser. It is expedient if the at least one outlet is provided on the housing section of the detergent dispenser, which is arranged in the direction of gravity below the receiving space. In this case, a number of outlets can be provided, which corresponds to the number of detergent stored in the cartridge or the number of the detergent receiving chambers.
Der zumindest eine Auslass des Reinigungsmitteldosiersystems mündet in eine Dosierkammer, welche mit dem Reinigungsmittel in operativer Verbindung steht. Dies bedeutet, dass die Dosierkammer über das Öffnungsmittel bzw. die Kanüle, und ggf. einem steuerbaren Ventil o. Ä. mit dem Reinigungsmittel verbunden ist. Der Dosierkammer kann eine Fördereinrichtung zugeordnet sein, mit welcher das Reinigungsmittel aus der Kartusche dem Spülraum zuführbar ist. Die Fördereinrichtung ist zweckmäßigerweise in der Dosierkammer angeordnet. Die Dosierung kann z.B. durch eine Pumpe vorgenommen werden. Alternativ kann die Abgabe über die Schwerkraft und die Dosierung über die Festlegung einer Auslaufzeit erfolgen. Diese Variante erzwingt, dass der öffenbare Verschluss in Schwerkraftrichtung unten angeordnet ist, wenn sich die Kartusche in Einbaulage in dem Reinigungsmitteldosiersystem befindet, was im Übrigen eine bevorzugte Anordnung darstellt.The at least one outlet of the detergent dosing system opens into a metering chamber which is in operative connection with the cleaning agent. This means that the metering chamber via the opening means or the cannula, and possibly a controllable valve o. Ä. connected to the cleaning agent. The metering chamber may be associated with a conveyor, with which the detergent is fed from the cartridge to the washing compartment. The conveyor is expediently arranged in the metering chamber. The dosage may e.g. be made by a pump. Alternatively, the delivery via gravity and the dosage on the determination of a flow time can be done. This variant forces the openable closure to be located in the direction of gravity at the bottom when the cartridge is in the installed position in the detergent dosing system, which is otherwise a preferred arrangement.
Das erfindungsgemäße Reinigungsmitteldosiersystem kann ferner zumindest eine weitere Kammer für ein festes Reinigungsmittel aufweisen. Das Vorsehen einer solchen weiteren Kammer weist den Vorteil auf, dass der Betrieb der Geschirrspülmaschine auch dann sichergestellt werden kann, wenn die wenigstens eine Kartusche keine Reinigungsmittel mehr enthält und der Benutzer keine weitere gefüllte Kartusche zur Hand hat.The detergent dosing system according to the invention may further comprise at least one further chamber for a solid detergent. The provision of such a further chamber has the advantage that the operation of the dishwasher can be ensured even if the at least one cartridge no longer contains cleaning agents and the user has no further filled cartridge at hand.
Bevorzugt ist das Reinigungsmitteldosiersystem derart angeordnet, dass es von einer Bedienperson nur bei geöffneter Tür erreichbar ist. So ist das Reinigungsmitteldosiersystem gemäß einer Variante in einer Seitenwand des Spülraums zwischen einem Oberkorb und einem Unterkorb der Geschirrspülmaschine angeordnet. Alternativ kann das Reinigungsmitteldosiersystem an einer gegenüber dem Spülraum verschwenkbar ausgebildeten Tür der Geschirrspülmaschine angeordnet sein. Die Ausbildung erfolgt in dieser Variante an der Tür derart, dass eine Bestückung des Reinigungsmittelspenders mit der Kartusche von der Stirnseite der Tür her erfolgt. Die Bestückung kann dabei im Bereich einer Blende der Tür oder einer Innentür der Tür der Geschirrspülmaschine erfolgen.The detergent dosing system is preferably arranged such that it can only be reached by an operator when the door is open. Thus, the detergent dosing system is arranged according to a variant in a side wall of the washing compartment between an upper basket and a lower basket of the dishwasher. Alternatively, the detergent dosing system can be arranged on a door of the dishwasher which is designed to be pivotable relative to the washing compartment. The training takes place in this variant on the door such that a placement of the detergent dispenser with the cartridge from the front side of the door takes place. The Assembly can take place in the region of a panel of the door or an inner door of the door of the dishwasher.

Neben der Aufnahme für die Kartusche weist der Reinigungsmittelspender 11 eine Kammer 27 zur Aufnahme eines festen Reinigungsmittels auf. Bei dem festen Reinigungsmittel kann es sich beispielsweise um einen 3-in-1-Tab handeln, welcher in die Kammer 27 eingelegt wird, wenn in dem Aufnahmeraum 15 keine oder eine leere Kartusche 50 enthalten ist. Das Vorsehen der Kammer 27 zur Aufnahme eines festen Reinigungsmittels ermöglicht es, die Geschirrspülmaschine auch dann zu nutzen, wenn die Kartusche 50 leer ist und keine gefüllte Kartusche verfügbar ist.In addition to the receptacle for the cartridge, the detergent dispenser 11 has a
Die Kammer 27 weist, wie dies aus
Durch die Integration der Expansionsöffnung in das Reinigungsmitteldosiersystem und die Möglichkeit, mit dem Reinigungsmitteldosiersystem sämtliche Reinigungsmittel und Betriebsmittel für den Betrieb der Geschirrspülmaschine zur Verfügung stellen zu können, ergibt sich ein im Vergleich zu herkömmlichen Geschirrspülmaschinen wesentlich einfacherer konstruktiver Aufbau. Insbesondere muss lediglich noch eine Öffnung für das Reinigungsmitteldosiersystem 10 in dem Spülraum der Geschirrspülmaschine vorgesehen werden. Weitere Öffnungen, wie diese bislang zur Bereitstellung der Expansionsöffnung und/oder der Zugabevorrichtung, notwendig sind, können damit entfallen. Hierdurch lässt sich der Herstellungsvorgang der Geschirrspülmaschine mit weniger Schritten bewerkstelligen. Weiterhin entfällt die Notwendigkeit, jede der Öffnungen für eines der genannten Funktionsteile mit einer aufwändigen Dichtung versehen zu müssen. Insgesamt lässt sich damit eine preiswertere Geschirrspülmaschine herstellen.The integration of the expansion opening into the detergent dosing system and the possibility of being able to provide all cleaning agents and operating means for the operation of the dishwasher with the detergent dosing system result in a considerably simpler constructional design compared to conventional dishwashers. In particular, only one opening for the detergent dosing system 10 has yet to be provided in the washing compartment of the dishwasher. Other openings, as previously necessary to provide the expansion opening and / or the adding device, can be dispensed with. As a result, the manufacturing process of the dishwasher can be accomplished with fewer steps. Furthermore, eliminates the need for each of the openings for one of said functional parts to be provided with a complex seal. Overall, this makes it possible to produce a cheaper dishwasher.
Eine beispielhafte Ausgestaltung der erfindungsgemäßen Kartusche 50 ist in
Die Kartusche ist bevorzugt aus einem Kunststoff gefertigt und weist eine Breite B von ca. 200 mm, eine Höhe H von ca. 125 mm und eine Tiefe von ca. 25 mm auf. Bei diesen Abmaßen lässt sich das Volumen der verschiedenen Kammern derart bemessen, dass die gewünschten 20 bis 40 Spülzyklen mittels einer Kartusche durchführbar sind.The cartridge is preferably made of a plastic and has a width B of about 200 mm, a height H of about 125 mm and a depth of about 25 mm. With these dimensions, the volume of the various chambers can be dimensioned such that the desired 20 to 40 rinsing cycles can be carried out by means of a cartridge.
Neben den Kammern 51a bis 51e verfügt die Kartusche 50 über eine weitere Kammer 52, welche mit einem oder mehreren Belüftungskanälen 53 in Verbindung steht. Der oder die Belüftungskanäle 53 ihrerseits weisen eine Verbindung zu den verschiedenen Kammern 51a bis 51e auf. Auf diese Weise ist sichergestellt, dass mit zunehmender Entleerung der Kammern 51a bis 51e sich kein Unterdruck in diesen aufbauen kann, wodurch das Zugeben von Reinigungsmitteln erschwert oder verfälscht würde. Die Belüftungskanäle 53 befinden sich bevorzugt in einem Deckel 54, welcher nach dem Befüllen der einzelnen Kammern 51a bis 51e mit den jeweiligen Reinigungsmitteln auf das Gehäuse der Kartusche aufgebracht ist. Der Deckel 54 kann ein Überdruckventil 55 aufweisen, welches gegebenenfalls bei bestimmten Reinigungsmittelkomponenten notwendig ist.In addition to the
Da die in der Kartusche 50 enthaltenen Reinigungsmittel erst nach und nach im Rahmen einer Mehrzahl von Spülzyklen dem Spülraum, genauer der in dem Spülraum umgewälzten Spülflotte, zudosiert werden, sind diese mit jedem Spülzyklus beträchtlichen absoluten Temperaturen und Temperaturschwankungen ausgesetzt. Um zu verhindern, dass die Eigenschaften der Reinigungsmittel sich aufgrund dessen mit der Zeit verändern, ist zumindest eine zum Spülraum hin gerichtete Gehäusewand 13 der Kartusche 50 und/oder der zum Spülraum hin gerichtete Deckel 14 des Reinigungsmitteldosiersystems 10 aus einem isolierenden Material gefertigt oder aber mit einer Isolation 33 umgeben. Hierdurch wird ein Wärmestrom vom Spülraum in Richtung des Reinigungsmitteldosiersystems bzw. der in der Kartusche bevorrateten Reinigungsmittel begrenzt, so dass die Langzeitstabilität der verwendeten Reinigungsmittel gewährleistet ist. Die Isolation 33 kann durch ein in dem Deckel oder dem betreffenden Gehäuseabschnitt der Kartusche angeordnetes Gasvolumen gebildet sein. Dieses die Isolation erzeugende Gasvolumen kann im Rahmen der Fertigung des Deckels bzw. der Kartusche eingebracht werden. Das hierbei verwendete Verfahren ist als Gasinnendruckverfahren (GID) bekannt.Since the detergent contained in the
Im Gehäuse 12 des Reinigungsmittelspenders 11 sind weiterhin Auslässe 19a bis 19e vorgesehen. Die Auslässe 19a bis 19e münden jeweils in eine Dosierkammer 20a bis 20e. Die Dosierkammern stehen jeweils über die Kanülen mit einer zugeordneten Kammer der Kartusche in Verbindung.In the
In jeder der Dosierkammern ist eine nicht näher dargestellte Fördereinrichtung angeordnet, welche das Fördern einer vorbestimmten Menge an Reinigungsmitteln in Spülraum bewirkt.In each of the metering chambers, a conveying device, not shown, is arranged, which causes the conveying of a predetermined amount of cleaning agents in the washing compartment.
Das Fördern des Reinigungsmittels kann dabei entweder ausschließlich unter Ausnutzung der Schwerkraft erfolgen. Die Fördereinrichtung kann jedoch auch nach dem Prinzip einer Pumpe aufgebaut sein, so dass durch einen entsprechenden Unterdruck Reinigungsmittel aus der Reinigungskammer in die Dosierkammer und durch einen entsprechenden Überdruck aus der Dosierkammer 20a in den Spülraum gefördert werden.The conveying of the cleaning agent can be done either exclusively by utilizing gravity. However, the conveyor may also be constructed according to the principle of a pump, so that are conveyed by a corresponding negative pressure detergent from the cleaning chamber into the metering chamber and by a corresponding pressure from the
