Die Hilfsstoffe können dann beispielsweise mit einer Flüssigkeit aus der Ausgabeeinheit ausgespült werden oder einfach in den Spülbehälter hineinfallen.During the rinsing process, the dispensing unit dispenses the auxiliary substances contained in the storage chambers, including, for example, various cleaning agents or rinse aids, into the rinsing container. For filling with auxiliaries, at least part of the dispensing unit can be at least partially pulled out of the washing container or pulled out, comparable to a drawer. The auxiliaries can then be rinsed out, for example, with a liquid from the dispensing unit or simply fall into the rinsing container.
Die Ausgabeeinheit ist in ihrer Grundform vorzugsweise im Wesentlichen quaderförmig oder kastenförmig ausgeführt. Die quaderförmige Grundform kann eventuell Ausschnitte oder Aussparungen mit beliebigen geometrischen Formen aufweisen, wenn es für den Einbau in den Spülbehälter oder die Funktionalität der Ausgabeeinheit von Vorteil ist. Die Ausgabeeinheit kann darüber hinaus aber auch jede weitere geeignete, geometrische Grundform aufweisen, beispielsweise im Wesentlichen kugelförmig, kegelförmig, zylinderförmig sein oder die Form eines vom Quader abweichenden Prisma besitzen. Darüber hinaus kann die Ausgabeeinheit aus einem Teil oder aus mehreren Teilen.aufgebaut sein. Umfasst die Ausgabeeinheit mehrere Teile, so kann beispielsweise ein Teil im Spülbehälter unbeweglich angeordnet sein und eventuell verschiedene Funktionselemente der Ausgabeeinheit umfassen und ein weiteres Teil zum Einfüllen von Hilfsstoffen aus dem Spülbehälter heraus- bzw. hervorziehbar ausgeführt sein. Alle Teile der Ausgabeeinheit sind vorzugsweise zu einer kompakten Einheit zusammengefasst.In its basic form, the dispensing unit is preferably made essentially cuboidal or box-shaped. The cuboidal basic shape may possibly have cutouts or recesses of any geometric shape, if it is for installation in the washing or the functionality of the output unit of advantage. In addition, however, the output unit can also have any further suitable basic geometrical shape, for example substantially spherical, conical, cylindrical or have the shape of a prism deviating from the parallelepiped. In addition, the output unit may be constructed of one or more parts. If the dispensing unit comprises several parts, then for example one part may be arranged immovably in the rinsing container and possibly comprise different functional elements of the dispensing unit and another part for filling in excipients may be made to extend out of the rinsing container or be pulled out. All parts of the output unit are preferably combined to form a compact unit.
Bei dem Verfahren gemäß Anspruch 27 zur Zuführung von Hilfsstoffen in ein flüssigkeitsführendes Haushaltsgerät, insbesondere eine Haushaltsgeschirrspülmaschine, mit einem Spülbehälter, der eine Beschickungsöffnung zum Einbringen zu reinigender Teile in den Spülbehälter aufweist, insbesondere unter Verwendung einer Vorrichtung nach Anspruch 1 oder eines der von Anspruch 1 abhängigen Ansprüche, wird wenigstens ein Teil einer im Spülbehälter angeordneten Ausgabeeinheit in Richtung der Beschickungsöffnung zumindest teilweise aus dem Spülbehälter herausgezogen und mit wenigstens einem Hilfsstoff befüllt und die Ausgabeeinheit gibt während eines Arbeitsvorgangs wenigstens einen Teil des wenigstens einen Hilfsstoffs in die Arbeitsflüssigkeit und/oder in den Spülbehälter ab.In the method according to claim 27 for supplying auxiliaries in a liquid-conducting domestic appliance, in particular a domestic dishwasher, with a washing container having a feed opening for introducing parts to be cleaned in the washing container, in particular using a device according to claim 1 or one of claim 1 dependent claims, at least a portion of a dispensing unit arranged in the washing container is at least partially pulled out of the washing container and filled with at least one excipient and the dispensing unit is at least a portion of the at least one excipient in a working liquid and / or in the Rinse tank off.
Ein Hauptvorteil der Vorrichtung und des Verfahrens gemäß der Erfindung ist, dass die Ausgabeeinheit wenigstens teilweise aus dem Spülbehälter herausziehbar ist und sich so sehr bequem mit den jeweiligen Hilfsstoffen befüllen lässt. Die Ausgabeeinheit ist vorzugsweise so im Spülbehälter platziert, dass sich der Bediener beim Hervorziehen und Befüllen der Ausgabeeinheit nicht vorbeugen, bücken oder sogar in die Hocke begeben muss. Die befüllte Ausgabeeinheit wird anschließend in den Spülbehälter zurückgeschoben. Das ist vor allem dann sehr einfach und schnell durchzuführen, wenn'die Ausgabeeinheit zum Befüllen nicht komplett aus dem Spülbehälter herausgenommen wird oder herausgenommen werden kann.A main advantage of the device and of the method according to the invention is that the dispensing unit can be pulled out of the washing container at least partially and can be filled very easily with the respective auxiliary substances. The dispensing unit is preferably placed in the rinsing container so that the operator does not have to lean forward, bend over or even crouch down when pulling out and filling the dispensing unit. The filled dispensing unit is then pushed back into the washing compartment. This is very easy and fast to carry out, especially if the dispensing unit can not be completely removed from the washing container for filling or can be removed.
Ein weitere Vorteil der Vorrichtung ist, dass sich die Ausgabeeinheit auf relativ einfache Weise an einen Hydraulikkreislauf bzw. Umwälzkreislauf der Arbeitsflüssigkeit im Haushaltsgerät anschließen lässt, da sie als kompakte Einheit in Innern des Spülbehälters angeordnet ist. Im Gegensatz zu dem meist üblichen Ausspülen der Reinigungsmittel aus den Dosierkammern durch Spritzwasser, lässt sich auf diese Weise eine kontrollierte Flüssigkeitszuführung und - verteilung auf verschiedene Bereiche der Ausgabeeinheit realisieren. Vor allem pulverförmige Hilfsstoffe können auf diese Weise vollständig gelöst und ausgetragen werden. Auch die Programmzyklusgestaltung kann auf vielfältige Weise erfolgen.Another advantage of the device is that the output unit can be connected in a relatively simple manner to a hydraulic circuit or circulation circuit of the working fluid in the household appliance, since it is arranged as a compact unit in the interior of the washing. In contrast For the most usual rinsing out of the detergent from the dosing by splashing, can be realized in this way a controlled liquid supply and - distribution to different areas of the output unit. Above all, powdery auxiliaries can be completely dissolved and discharged in this way. The program cycle design can be done in many ways.
Aufgrund der Möglichkeit verschiedene Funktionselemente in die kompakte Ausgabeeinheit zu integrieren, reduzieren sich zudem die Systemkosten.Due to the possibility of integrating different functional elements into the compact output unit, the system costs are also reduced.
In einer besonders vorteilhaften Ausführungsform der Vorrichtung gemäß der Erfindung ist die Ausgabeeinheit zumindest teilweise aus dem Spülbehälter herausnehmbar. Sie kann dann zum Befüllen an jeden beliebigen Ort verbracht werden, beispielsweise um ein sauberes Einfüllen, insbesondere von pulverförmigen oder aus Pulver gepressten Hilfsstoffen zu ermöglichen. Ferner lässt sich die Ausgabeeinheit auf diese Weise leicht reinigen, sollte dies gewünscht sein.In a particularly advantageous embodiment of the device according to the invention, the dispensing unit is at least partially removable from the washing container. It can then be spent for filling at any location, for example, to allow a clean filling, especially of powdered or powder-pressed excipients. Furthermore, the dispensing unit can be easily cleaned in this way, should this be desired.
Gemäß der Erfindung ist die Ausgabeeinheit an einer Innenseite einer Wand des Spülbehälters zumindest teilweise beweglich oder bewegbar angeordnet. Das Einbringen von zu reinigenden Teilen in den Spülbehälter wird. dann durch die im Spülbehälter befindliche Ausgabeeinheit nicht beeinträchtigt und der Raum im Spülbehälter kann bestmöglich ausgenützt werden. Besonders bevorzugt ist es, wenn die Ausgabeeinheit an der Innenseite einer Decke des Spülbehälters zumindest teilweise beweglich oder bewegbar angeordnet ist, da neben der besonders guten Zugänglichkeit, die beste Raumausnutzung erfolgen kann. Darüber hinaus erfolgt in diesem Fall die Ausgabe des Hilfsstoffes von oben in Richtung des Bodens, so dass der Hilfsstoff relativ gleichmäßig über den Spülbehälter verteilt wird und dadurch optimal ausgenutzt werden kann. Es ist aber auch denkbar die Ausgabeeinheit an einer Seitenwand des Spülbehälters zumindest teilweise bewegbar oder beweglich anzuordnen. Sie sollte dabei möglichst an einer Stelle vorgesehen sein, an der sie einfach herauszuziehen und zu befüllen ist, jedoch nicht die Funktion der möglichen Einbauten in den Spülbehälter wie Geschirrkorb oder Sprüharm behindert.According to the invention, the dispensing unit is arranged on an inner side of a wall of the washing container at least partially movable or movable. The introduction of parts to be cleaned in the washing is. then not affected by the output unit located in the washing and the space in the washing can be utilized to the maximum extent possible. It is particularly preferred if the output unit is arranged on the inside of a cover of the washing container at least partially movable or movable, since in addition to the particularly good accessibility, the best space utilization can be done. In addition, in this case, the output of the excipient of above in the direction of the bottom, so that the excipient is relatively evenly distributed over the washing and thus can be optimally utilized. However, it is also conceivable to arrange the dispensing unit on a side wall of the washing container at least partially movable or movable. It should be provided as possible at a location where it is easy to pull out and fill, but does not hamper the function of possible installations in the washing such as dish rack or spray arm.
Vorteilhaft ist es auch, wenn an der Innenseite der Wand des Spülbehälters, an der die Ausgabeeinheit angeordnet ist, und/oder an der Ausgabeeinheit wenigstens ein Mittel zur Befestigung der Ausgabeeinheit und/oder wenigstens ein Mittel zur Führung wenigstens eines Teils der Ausgabeeinheit im Spülbehälter vorgesehen sind bzw. ist. Die Mittel können vorzugsweise wenigstens eine an der Wändinnenseite und/oder an der Ausgabeeinheit vorgesehene Führungsschiene umfassen. Die Führungsschienen können beispielsweise so ausgeführt sein, dass an der Wand und an der Ausgabeeinheit vorgesehene korrespondierende Führungsschienen ineinander eingreifen. Weiterhin umfassen Mittel zur Befestigung und Führung der Ausgabeeinheit beispielsweise an der Wandinnenseite angebrachte Halterungen, die gleichzeitig zur Führung der Ausgabeeinheit dienen können. Sehr einfache solche Halterungen sind beispielsweise Rechteck- oder U-Profile.It is also advantageous if at least one means for fixing the dispensing unit and / or at least one means for guiding at least a part of the dispensing unit in the washing compartment is provided on the inside of the wall of the washing container on which the dispensing unit is arranged and / or on the dispensing unit are or is.

Furthermore, means for fixing and guiding the output unit comprise, for example, on the inside wall mounted brackets, which can serve to guide the output unit at the same time. Very simple such mounts are, for example, rectangular or U-profiles.
In einer besonders zweckmäßigen Ausführungsform ist an der Ausgabeeinheit wenigstens einen Griff vorgesehen zum Bewegen der Ausgabeeinheit und/oder wenigstens ein Mittel vorgesehen, das die Ausgabeeinheit in einem eingeschobenen Zustand an ihrem Platz hält. Der Griff kann entweder auf die Ausgabeeinheit aufgesetzt oder als Vertiefung in der Ausgabeeinheit ausgebildet sein. Als Mittel, das die Ausgabeeinheit in einem eingeschobenen Zustand an ihrem Platz hält ist beispielsweise ein Riegel denkbar, der vor dem Herausziehen gelöst werden muss. In einer einfachen Ausführungsform kann das Mittel aber auch lediglich wenigstens eine geeignete Nase oder Welle umfassen, die in eine entsprechende Vertiefung (Kerbe oder Rille) eingreift, so dass sich die Ausgabeeinheit bei einer bestimmten Zugkraft bewegen lässt, jedoch beispielsweise beim Kippen des Haushaltsgeräts nicht herausfallen kann.In a particularly expedient embodiment, at least one handle is provided on the dispensing unit for moving the dispensing unit and / or at least one means for holding the dispensing unit in place in an inserted state. The handle can either be placed on the dispensing unit or formed as a recess in the dispensing unit. As a means, that the output unit holds in an inserted state in place, for example, a bolt is conceivable that must be solved before pulling out. In a simple embodiment, however, the means may also comprise only at least one suitable nose or shaft which engages in a corresponding recess (notch or groove) so that the dispensing unit can be moved at a certain tensile force, but not fall out, for example, when the household appliance is tilted can.
Vorzugsweise umfasst die Ausgabeeinheit wenigstens eine Vorratskammer zur Aufnahme wenigstens eines Hilfsstoffs.

The dispensing unit and / or the at least one storage chamber then preferably have at least one filling opening for at least one auxiliary substance and at least one dispensing opening for the at least one auxiliary substance.
Wenigstens eine Einfüllöffnung ist bevorzugt zu der Wand des Spülbehälters, an der die Ausgabeeinheit angeordnet ist, hin ausgerichtet. Je nach Form und Einbaulage der Ausgabeeinheit kann jedoch auch eine andere Ausrichtung der Einfüllöffnungen vorteilhaft sein.At least one filling opening is preferably aligned with the wall of the washing container on which the dispensing unit is arranged. Depending on the shape and installation position of the dispensing unit, however, a different orientation of the filling openings may also be advantageous.
Wenigstens eine Ausgabeöffnung ist vorzugsweise in den Spülbehälter ausgerichtet, insbesondere in eine Richtung senkrecht zu der Wand des Spülbehälters, an der die Ausgabeeinheit angeordnet ist. Sind mehrere Ausgabeöffnungen vorgesehen, so können diese auch in verschiedene Richtungen ausgerichtet sein. Auch für die Ausgabeöffnungen gilt, dass je nach Form und Einbaulage der Ausgabeeinheit die jeweils geeignete Ausgaberichtung bzw. die Richtung in die die Ausgabeöffnungen ausgerichtet sind, ausgewählt wird.At least one dispensing opening is preferably aligned in the rinsing container, in particular in a direction perpendicular to the wall of the rinsing container, on which the dispensing unit is arranged. If several dispensing openings are provided, they can also be aligned in different directions. Also applies to the output openings that, depending on the shape and mounting position of the output unit, the respectively suitable output direction and the direction in which the output openings are aligned, is selected.
In einer besonders bevorzugten Ausführungsform ist die Ausgabeeinheit an der Innenseite der Decke des Spülbehälters angeordnet, wobei wenigstens eine Ausgabeöffnung und wenigstens eine Einfüllöffnung jeweils an gegenüberliegenden Seiten der Ausgabeeinheit und/oder der Vorratskammer angeordnet sind und im Wesentlichen voneinander weg weisen, und wobei die Einfüllöffnung zu der Innenseite der Decke hin ausgerichtet ist.In a particularly preferred embodiment, the dispensing unit is arranged on the inside of the cover of the washing container, wherein at least one dispensing opening and at least one filling opening are respectively arranged on opposite sides of the dispensing unit and / or the storage chamber and substantially away from each other, and wherein the filling opening to the inside of the ceiling is aligned.
Zumindest ein Teil der Ausgabeeinheit lässt sich vorzugsweise so weit aus dem Spülbehälter herausziehen, dass die wenigstens eine Einfüllöffnung frei liegt. Auf diese Weise ist ein problemloses Befüllen der Ausgabeeinheit und/oder der wenigstens einen Vorratskammer möglich.At least part of the dispensing unit can preferably be pulled out of the washing container so far that the at least one filling opening is exposed. In this way, trouble-free filling of the dispensing unit and / or the at least one storage chamber is possible.
Insbesondere vorteilhaft ist es wenn die wenigstens eine Vorratskammer so ausgeführt ist, dass sie maximal eine vorgegebene Menge Hilfsstoff für einen Arbeitsvorgang, insbesondere Spülvorgang, oder maximal eine vorgegebene Menge Hilfsstoff für mehrere Arbeitsvorgänge aufnehmen kann. Ein Arbeitsvorgang umfasst alle Spülphasen eines Arbeitsprogramms.It is particularly advantageous if the at least one storage chamber is designed so that it can accommodate a maximum of a predetermined amount of excipient for a single operation, in particular rinsing, or a maximum of a predetermined amount of excipient for several operations. A work process includes all wash phases of a work program.
Besonders vorteilhaft ist es, wenn die Ausgabeeinheit wenigstens zwei Vorratskammern zur Aufnahme von Hilfsstoffen umfasst, insbesondere wenigstens eine Vorratskammern zur Aufnahme eines Reinigungsmittels und wenigstens eine Vorratskammer zur Aufnahme eines Spülhilfsmittels, zum Beispiel ein Klarspülmittel.It is particularly advantageous if the dispensing unit comprises at least two storage chambers for receiving auxiliaries, in particular at least one storage chamber for receiving a cleaning agent and at least one storage chamber for receiving a rinse aid, for example a rinse aid.
Die Ausgabeeinheit kann vorzugsweise so ausgeführt sein, dass die wenigstens eine Vorratskammer für das Spülhilfsmittel eine vorgegebene Menge Hilfsstoff für mehrere Arbeitsvorgänge aufnehmen kann und die wenigstens eine Vorratskammer für das Reinigungsmittel eine vorgegebene Menge Hilfsstoff für einen Spülvorgang aufnehmen kann. Dazu kann die wenigstens eine Vorratskammer für das Spülhilfsmittel beispielsweise auch ein größeres Volumen aufweisen als die wenigstens eine Vorratskammer für das Reinigungsmittel. Das die Vorratskammer für das Spülhilfsmittel eine vorgegebene Menge Hilfsstoff für mehrere Arbeitsvorgänge aufnehmen kann hat den Vorteil, dass nicht bei jedem Spülvorgang Spülhilfsmi'ttel nachgefüllt werden muss, von dem häufig lediglich eine relativ geringe Menge pro Spülvorgang benötigt wird. Außerdem lässt sich der Hilfsstoff auf diese Weise genauer dosieren.The dispensing unit may preferably be designed such that the at least one rinse aid storage chamber can receive a predetermined amount of adjuvant for a plurality of operations and the at least one storage chamber for the detergent can receive a predetermined amount of excipient for a rinse. For this purpose, the at least one storage chamber for the rinsing aid, for example, also have a larger volume than the at least one storage chamber for the cleaning agent. The fact that the storage chamber for the rinsing aid can absorb a predetermined amount of auxiliary substance for a plurality of working operations has the advantage that it is not necessary to refill rinsing aid with each rinsing process, of which frequently only a relatively small amount per rinsing process is required. In addition, the excipient can be dosed more accurately in this way.
In einer besonders bevorzugten Ausführungsform der Vorrichtung gemäß der Erfindung ist die Ausgabeeinheit an einen Hydraulikkreislauf bzw. Umwälzkreis einer Arbeitsflüssigkeit im Haushaltsgerät angeschlossen, so dass wenigstens ein Teil der umgewälzten Arbeitsflüssigkeit bzw. Spülflüssigkeit die Ausgabeeinheit durchströmt. Der Anschluss an den Hydraulikkreislauf kann auf einfache Weise dadurch erfolgen, dass Arbeitsflüssigkeit aus einer Zuführung an oder in der Spülbehälterwand über eine Öffnung oder Düse an oder in der Spülbehälterwand heraus und in die Einfüllöffnung der Ausgabeeinheit fließt.In a particularly preferred embodiment of the device according to the invention, the dispensing unit is connected to a hydraulic circuit or circulating circuit of a working fluid in the household appliance, so that at least part of the circulated working fluid or rinsing fluid flows through the dispensing unit. The connection to the hydraulic circuit can be carried out in a simple manner in that working fluid flows from a supply to or in the washing compartment wall via an opening or nozzle on or in the washing compartment wall and into the filling opening of the dispensing unit.
Vorteilhaft kann es aber auch sein, wenn die Ausgabeeinheit über Anschlussmittel trennbar oder nicht trennbar mit dem Hydraulikkreislauf verbunden ist. Als Anschlussmittel können beispielweise Schläuche vorgesehen sein, die mit der Ausgabeeinheit verbunden sind und die einen Teil der Arbeitsflüssigkeit aus dem Umwälzkreis auf die Ausgabeeinheit führen. Die Ausgabeeinheit ist dann in der Regel nicht vom Schlauch trennbar, so dass beim Hervorziehen der Ausgabeeinheit der Schlauch mitbewegt wird. Eine Möglichkeit die Ausgabeeinheit trennbar an den Umwälzkreis anzuschließen wäre beispielsweise eine trennbare Steckverbindung bzw. Steckkupplung, über die die Ausgabeeinheit im eingeschobenen zustand mit'einem Rohr aus dem Umwälzkreis verbunden ist. Darüber hinaus sind alle weiteren bekannten und geeigneten Anschlussmöglichkeiten an einen Hydraulikkreislauf verwendbar.But it may also be advantageous if the output unit is connected via connection means separable or not separable with the hydraulic circuit. As connecting means, for example, hoses may be provided which are connected to the dispensing unit and which carry a portion of the working fluid from the circulating circuit to the dispensing unit. The output unit is then usually not separable from the hose, so that when pulling out the output unit of the hose is moved. A possibility the Disconnect output unit to connect to the circulation would be, for example, a separable connector or plug-in coupling, via which the output unit is connected in the inserted state mit'einem tube from the circulation circuit. In addition, all other known and suitable connection options to a hydraulic circuit can be used.
Vorzugsweise ist wenigstens eine Flüssigkeitsverteileinrichtung vorgesehen, über die Arbeitsflüssigkeit auf einzelne Bereiche in der Ausgabeeinheit verteilt wird und/oder über die die Flüssigkeitsmenge und/oder die Flüssigkeitsverteilung steuerbar sind bzw. ist. Die wenigstens eine Flüssigkeitsverteileinrichtung kann beispielsweise in die Ausgabeeinheit integriert sein.Preferably, at least one liquid distribution device is provided, is distributed over the working fluid to individual areas in the dispensing unit and / or via which the amount of liquid and / or the liquid distribution can be controlled or is. The at least one liquid distribution device can be integrated, for example, in the dispensing unit.
In einer vorteilhaften Ausführungsform ist eine Flüssigkeitsverteileinrichtung zur Dosierung der Arbeitsflüssigkeit in wenigstens eine Vorratskammer vorgesehen. Die Vorratskammer ist vorzugsweise so ausgeführt, dass durch die zudosierte Arbeitsflüssigkeit das Hilfsmittel wenigsten teilweise durch die Ausgabeöffnung aus der Vorratskammer ausgetragen wird.In an advantageous embodiment, a liquid distribution device for metering the working fluid is provided in at least one storage chamber. The storage chamber is preferably designed so that the aid is discharged at least partially through the dispensing opening from the storage chamber by the metered working fluid.
Ein pulverförmiges Reinigungsmittel beispielsweise kann dabei zunächst mit Arbeitsflüssigkeit beaufschlagt.und in einen fließfähigen Zustand überführt werden, bevor es in den Spülbehälter gespült wird. Dadurch wird zum einen ein nahezu vollständiges Austragen des Reinigungsmittels aus der Vorratskammer und zum anderen eine gleichmäßigere Konzentrationsverteilung des Reinigungsmittels im Spülbehälter erreicht.A powdered cleaning agent, for example, can first be charged with working fluid and transferred to a flowable state before it is flushed into the washing compartment. As a result, on the one hand almost complete discharge of the cleaning agent from the storage chamber and, on the other hand, a more uniform concentration distribution of the cleaning agent in the washing container is achieved.
Besonders vorteilhaft kann es auch sein, wenn die Ausgabeeinheit wenigstens eine Sprüheinheit zum Versprühen wenigstens eines Teils der umgewälzten Arbeitsflüssigkeit im Spülbehälter umfasst, insbesondere wenigstens eine Sprühdüse und/oder wenigstens einen Sprüharm. Dadurch kann Arbeitsflüssigkeit gleichmäßig verteilt von oben auf das zu reinigende Gut aufgebracht werden, was die Reinigungswirkung im Haushaltsgerät erhöht. Zur Versorgung der wenigstens einen Sprüheinheit mit Arbeitsflüssigkeit sind bzw. ist in der Ausgabeeinheit vorzugsweise wenigstens ein Kanal und/oder wenigstens ein Mittel vorgesehen, wobei das Mittel beispielsweise eine Schlauchleitung oder ein Rohr sein kann.It can also be particularly advantageous if the dispensing unit comprises at least one spray unit for spraying at least a portion of the circulated working fluid in the washing compartment, in particular at least one spray nozzle and / or at least one spray arm. As a result, working fluid can be applied evenly distributed from above on the material to be cleaned, which increases the cleaning effect in the household appliance. For supplying the at least one spray unit with working fluid, at least one channel and / or at least one means is or are preferably provided in the dispensing unit, wherein the means may be, for example, a hose line or a pipe.
Insbesondere vorteilhaft ist es, wenn eine Flüssigkeitsverteileinrichtung zur Dosierung der Arbeitsflüssigkeit in die wenigstens eine Sprüheinheit vorgesehen ist. Einzelne Sprühdüsen können so beispielsweise gezielt angesteuert werden, so dass zum Beispiels je nach Verschmutzungsgrad mehr oder weniger Arbeitsflüssigkeit aufgesprüht werden kann. Die Flüssigkeitsverteileinrichtung zur Dosierung der Arbeitsflüssigkeit in die wenigstens eine Sprüheinheit entspricht vorzugsweise der Flüssigkeitsverteileinrichtung zur Dosierung der Arbeitsflüssigkeit in die wenigstens eine Vorratskammer. In diesem Fall ist nur eine Steuereinheit zur Flüssigkeitsverteilung notwendig.It is particularly advantageous if a liquid distribution device is provided for metering the working fluid into the at least one spray unit. For example, individual spray nozzles can be specifically controlled so that, for example, depending on the degree of soiling, more or less working fluid can be sprayed on. The liquid distribution device for metering the working fluid into the at least one spray unit preferably corresponds to the liquid distribution device for metering the working fluid into the at least one storage chamber. In this case, only one control unit for liquid distribution is necessary.
In einer vorteilhaften Ausführungsform ist in der Ausgabeeinheit wenigstens ein Sensor zur Überwachung eines Füllniveaus in einer Vorratskammer integriert. Umfasst die Ausgabeeinheit wenigstens eine Anzeigeeinheit, insbesondere wenigstens eine LED oder wenigstens ein Display, und/oder wenigstens eine Einheit zur Signalübertragung an eine Steuereinheit, so kann das in der Vorratskammer detektierte Füllniveau an der Ausgabeeinheit oder auch an einer Bedienfläche des Haushaltsgeräts angezeigt werden oder auch zur Steuerung eines Arbeitsvorgangs genutzt werden.In an advantageous embodiment, at least one sensor for monitoring a filling level is integrated in a supply chamber in the dispensing unit. If the output unit comprises at least one display unit, in particular at least one LED or at least one display, and / or at least one unit for signal transmission to a control unit, then the fill level detected in the storage chamber be displayed on the output unit or on a control surface of the household appliance or be used to control a work process.
Darüber hinaus ist kann es vorteilhaft sein, wenn die Ausgabeeinheit wenigstens eine Einrichtung zur Überwachung der Beladung des Spülbehälters und/oder zur Überwachung einer Sprüharmdrehung umfasst. Als Einrichtung zur über Überwachung der Beladung kann beispielsweise ein optisches Sensorsystem zum Einsatz kommen, dass eine Geschirrmenge in der Geschirrspülmaschine bestimmt. Die ermittelten Daten zur Beladung des Spülbehälters und/oder zur Sprüharmrotation können ebenfalls zur Steuerung eines Arbeitsvorgangs herangezogen werden.Moreover, it may be advantageous if the output unit comprises at least one device for monitoring the loading of the washing container and / or for monitoring a spray arm rotation. As a device for monitoring the loading, it is possible, for example, to use an optical sensor system that determines a quantity of dishes in the dishwasher. The determined data for loading the rinsing container and / or the Sprüharmrotation can also be used to control a work process.
In einer zweckmäßigen Ausführungsform umfasst die Ausgabeeinheit zudem ein Beleuchtungslampe zur Beleuchtung des Spülbehälterinneren.In an expedient embodiment, the dispensing unit also comprises an illumination lamp for illuminating the interior of the washing tub.
Das flüssigkeitsführende Haushaltsgerät, insbesondere die Haushaltsgeschirrspülmaschine, gemäß Anspruch 26 umfasst eine Vorrichtung zur Zuführung von Hilfsstoffen, insbesondere nach Anspruch 1 oder einen der von Anspruch 1 abhängigen Ansprüchen.The liquid-conducting domestic appliance, in particular the domestic dishwasher, according to claim 26, comprises a device for supplying auxiliaries, in particular according to claim 1 or one of the dependent claims of claim 1.
Bei dem Verfahren zur Zuführung von Hilfsstoffen in ein flüssigkeitsführendes Haushaltsgerät ist es insbesondere vorteilhaft, wenn eine Arbeitsflüssigkeit die Ausgabeeinheit durchströmt und wenigstens ein Hilfsstoff zumindest zu einem Teil mit der Arbeitsflüssigkeit in den Spülbehälter ausgespült wird. Der Hilfsstoff kann auf diese Weise vollständig gelöst und gleichmäßig im Spülbehälter verteilt werden.In the method for supplying auxiliaries in a liquid-conducting domestic appliance, it is particularly advantageous if a working fluid flows through the dispensing unit and at least one adjuvant is flushed out at least in part with the working fluid in the washing. The excipient can be completely dissolved in this way and evenly distributed in the washing.
Des Weiteren kann es vorteilhaft sein, wenn wenigstens ein Teil wenigstens eines Hilfsstoffs durch die Wirkung der Schwerkraft aus der Ausgabeeinheit in den Spülbehälter fällt. Insbesondere pulverförmige oder aus Pulver verpresste Hilfsstoffe, z.B. Reinigungsmitteltabletten, lassen sich auf diese Weise einfach dosieren.Furthermore, it may be advantageous if at least part of at least one excipient falls out of the dispensing unit into the rinsing container by the action of gravity. In particular powdered or powdered excipients, e.g. Detergent tablets, can be easily dosed in this way.
Die Erfindung wird im Folgenden anhand von Ausführungsbeispielen und unter Bezugnahme auf die beiliegenden Zeichnungen weiter erläutert.The invention will be further elucidated on the basis of exemplary embodiments and with reference to the accompanying drawings.
