Abstract
Description
Die Erfindung betrifft ein wasserführendes Haushaltsgerät, insbesondere Geschirrspülmaschine, mit einer Steuereinrichtung zur Durchführung wenigstens eines Spülprogramms, wobei mit der Steuereinrichtung in Abhängigkeit von wenigstens einem verwendeten Reinigungsmittel das Spülprogramm anpassbar ist.The invention relates to a water-conducting domestic appliance, in particular a dishwasher, with a control device for carrying out at least one washing program, wherein the washing program can be adapted with the control device as a function of at least one cleaning agent used.
Geschirrspülmaschinen weisen bekanntermaßen innenseitig an der Gerätetür Zugabeeinrichtungen für pulverförmige Reiniger und normalerweise flüssige Klarspüler auf. Zusätzlich ist am Spülbehälterboden eine Zugabeeinrichtung für einen Enthärter vorgesehen. Alternativ zu diesen Einzelkomponenten sind auch Kombinationsprodukte in Tablettenform bekannt, in denen die Wirkstoffkomponenten, wie etwa Reiniger, Klarspüler und Enthärter, als Bestandteile enthalten sind.Dishwashers are known to have on the inside of the door on addition devices for powdered cleaner and usually liquid rinse aid. In addition, an addition device for a softener is provided at the Spülbehälterboden. As an alternative to these individual components, combination products in tablet form are also known in which the active ingredient components, such as cleaners, rinse aids and softeners, are contained as constituents.
Damit auch bei Verwendung der oben genannten Kombinationsprodukte ein zufriedenstellendes Spülergebnis erzielt wird, kann ein erhöhter Energiebedarf während des Spülganges erforderlich sein. So ist eine gattungsgemäße Geschirrspülmaschine mit einer Steuereinrichtung zur Durchführung eines Spülprogramms bekannt, die in Abhängigkeit davon, ob Kombinationsprodukte verwendet werden oder nicht, das Spülprogramm anpasst. Die Anpassung des Spülprogrammes kann durch eine benutzerseitige manuelle Aktivierung einer entsprechenden Taste, zum Beispiel eine "3in1-Taste", erfolgen. Alternativ kann die Maschinensteuerung der Geschirrspülmaschine automatisch erkennen, dass ein Multifunktionsprodukt eingesetzt wird. Hierzu wird das Fehlen oder Vorhandensein von Klarspülmittel für die Entscheidung herangezogen, ob ein herkömmliches Spülprogramm oder ein sogenanntes 3in1-Spülgrogramm durchzuführen ist.In order to achieve a satisfactory rinsing result even when using the combination products mentioned above, an increased energy requirement during the rinse cycle may be required. Thus, a generic dishwasher with a control device for performing a wash program is known, which adjusts the wash program depending on whether combination products are used or not. The adjustment of the wash program can be done by a user-side manual activation of a corresponding button, for example, a "3in1 button". Alternatively, the machine controller of the dishwasher can automatically recognize that a multifunction product is being used. For this purpose, the absence or presence of rinse aid is used to decide whether to perform a conventional rinse program or a so-called 3-in-1 rinse program.
Die in Tablettenform angebotenen Kombinationsprodukte können sich je nach Hersteller in ihrer Stoffzusammensetzung und somit in ihrem Leistungsspektrum stark unterscheiden. Vor diesem Hintergrund ist die aus dem Stand der Technik bekannte Groberkennung, mit der nur das Fehlen oder Vorhandensein von Klarspüler erfassbar ist, für eine genau abgestimmte Anpassung des Spülprogramms an das jeweils verwendete Kombinationsprodukt nicht geeignet.Depending on the manufacturer, the combination products offered in tablet form can differ greatly in their substance composition and thus in their range of performance. Against this background, the coarse detection known from the prior art, with which only the absence or presence of rinse aid can be detected, is not suitable for a precisely matched adaptation of the rinse program to the respective combination product used.

Gemäß dem kennzeichnenden Teil des Patentanspruches 1 ist eine Analyseeinheit zur Erkennung des Reinigungsmittels vorgesehen, mittels der eine Stoffzusammensetzung des Reinigungsmittels zumindest teilweise identifizierbar ist, wobei die Analyseeinheit mit der Steuereinrichtung zur Übertragung von von der Analyseeinheit ermittelten Analysedaten von der Analyseeinheit zu der Steuereinheit verbunden ist. Auf dieser Grundlage kann dann die Steuereinrichtung - genau abgestimmt auf das jeweils verwendete Reinigungsmittel - das jeweils eingestellte Spülprogramm zum Beispiel mit Bezug auf die Prozessparameter, etwa Prozesstemperaturen oder die Zeitdauer, anpassen.According to the characterizing part of
Erfindungsgemäß erfolgt daher nicht nur eine Bestimmung, ob ein Kombinationsprodukt verwendet wird oder nicht, sondern zusätzlich noch zumindest teilweise eine Bestimmung der Stoffzusammensetzung des angewendeten Kombinationsproduktes.According to the invention, therefore, not only a determination is made as to whether a combination product is used or not, but additionally at least partially a determination of the composition of the applied combination product.
Auf diese Weise können bei einer Anpassung des durchzuführenden Spülprogrammes detailliertere Informationen mit Bezug auf die spezifische Funktionalität des verwendeten Reinigungsmittels zugrundegelegt werden. Für eine einfache sowie betriebssichere Identifizierung kann das Reinigungsmittel als Zuschlagstoff eine Markierungskomponente aufweisen, mit der eine eindeutige Identifizierung des Reinigungsmittels durch die Analyseeinheit des Haushaltsgerätes weiter vereinfacht wird. Die Markierungskomponente des Reinigungsmittels kann bevorzugt weitere Informationen über den Hersteller, über die Menge oder Charge aufweisen, auf deren Grundlage eine weitere Anpassung der Temperaturführung, der eingesetzten Wassermenge, etc. während des Spülprogramms erfolgen kann.In this way, more detailed information relating to the specific functionality of the cleaning agent used can be used when adapting the washing program to be carried out. For a simple and reliable identification, the cleaning agent may have as an additive a marking component with which a clear identification of the cleaning agent is further simplified by the analysis unit of the household appliance.

Hierzu können das Haushaltsgerät und das zumindest eine Reinigungsmittel in einem System oder Verbund zusammengefasst sein, in dem das Erfassungsvermögen der Analyseeinheit des Haushaltsgeräts und das Reinigungsmittel zumindest grob aufeinander abgestimmt sind. In dem Verbund kann sich bei einer Reihe von unterschiedlichen Reinigungsmitteln auf den Einsatz vorgegebener Markierungskomponenten verständigt sein, die vom Haushaltsgerät identifizierbar sind.Preferably, home appliance manufacturers and detergent manufacturers can agree on a standard in which certain detergent components, such as the special marking components, are recognized by the analysis unit of the household appliance and adjusted depending on the detected component of the household appliance operation. For this purpose, the household appliance and the at least one cleaning agent can be combined in a system or composite in which the detection capacity of the analysis unit of the household appliance and the cleaning agent are at least coarsely coordinated. In the composite can be agreed in a number of different cleaning agents on the use of predetermined marking components that are identifiable by the household appliance.
Alternativ dazu kann auf solche Markierungskomponenten verzichtet werden und die Analyseeinheit unmittelbar insbesondere solche Wirkstoffkomponenten des Reinigungsmittels erfassen, die für das Spülergebnis von Bedeutung sind. Eine Abstimmung bezüglich des Einsatzes von Markierungskomponenten braucht in diesem Fall nicht zu erfolgen.Alternatively, it is possible to dispense with such labeling components and the analysis unit immediately detect, in particular, such active ingredient components of the cleaning agent that are of importance for the rinsing result. A vote on the use of marking components need not be made in this case.
Wie bereits oben erwähnt, kann die Markierungskomponente als Zuschlagstoff in das Reinigungsmittelprodukt eingebaut sein und ansonsten keine weitere Reinigungsfunktion aufweisen. Alternativ kann die Markierungskomponente des Reinigungsmittels in Doppelfunktion zugleich auch eine Wirkstoffkomponente zur Reinigung des Spülguts sein.As already mentioned above, the marking component can be incorporated as an additive in the detergent product and otherwise have no further cleaning function. Alternatively, the marker component of the detergent in dual function can also be an active ingredient component for cleaning the items to be washed.
Die Erfindung ist insbesondere anwendbar bei Kombinationsprodukten, die unterschiedliche Wirkstoffkomponenten aufweisen, etwa Reinigerkomponenten, Enthärterkomponenten und/oder Klarspülkomponenten. Deren Leistungsspektren können sich bei unterschiedlichen Herstellern stark unterscheiden, wodurch eine genaue Abstimmung des Spülprogramms nur durch die erfindungsgemäß vorgeschlagene Erkennung der Stoffzusammensetzung des Reinigungsmittels erzielt werden kann.The invention is particularly applicable to combination products having different active ingredient components, such as cleaner components, softener components and / or rinse aid components. Their power spectra can vary greatly with different manufacturers, whereby a precise tuning of the washing program can only be achieved by the invention proposed detection of the composition of the detergent.
Zur Erfassung des für den Spülgang verwendeten Reinigungsmittels kann die Analyseeinheit einen Sensor aufweisen. Dieser kann unmittelbar in der Reinigungsmittel-Zugabeeinrichtung oder im Flüssigkeitskreislauf des Haushaltsgerätes derart integriert sein, dass die in der Spülflüssigkeit gelösten Wirk- und/oder Markierungskomponenten erfasst werden können. Die so erfassten Komponenten können mit jeweils in der Analyseeinheit hinterlegten Modellkomponenten verglichen werden. Bei Übereinstimmung mit einer der Modellkomponenten kann die Analyseeinheit ein Steuersignal zur Steuereinrichtung leiten, auf dessen Grundlage das durchzuführende Spülprogramm angepasst werden kann.For detecting the cleaning agent used for the rinse, the analysis unit may comprise a sensor. This can be integrated directly in the detergent-adding device or in the liquid circuit of the household appliance such that the dissolved in the rinsing liquid active and / or marking components can be detected. The components detected in this way can be compared with model components stored in each case in the analysis unit. If in accordance with one of the model components, the analysis unit can forward a control signal to the control device, on the basis of which the rinsing program to be carried out can be adapted.

Es kann jedoch auch vorgesehen sein, ein ungelösten Reinigungsmittel zu identifizieren.In a preferred embodiment it is provided that the analysis unit is designed for the analysis of a liquid, in particular water-dissolved cleaning agents. However, it may also be provided to identify an undissolved cleaning agent.
Dabei kann in einer bevorzugten Ausführungsform vorgesehen sein, dass die Analyseeinheit zur Durchführung einer Absorptions- und/oder Reflexionsmessung ausgebildet ist. So können als Markierungskomponenten Substanzen verwendet werden, die mit einer derartigen Messung erfasst werden können, wobei sich bei der Messung Querempfindlichkeiten mit anderen Substanzen der Reinigungsmittel und/oder Anschmutzungen auf dem Spülgut ausgeschlossen werden können. Gleiches gilt für die Messung beeinflussende Wechselwirkungen der Substanzen untereinanderIt can be provided in a preferred embodiment that the analysis unit is designed to carry out an absorption and / or reflection measurement. So can be used as marking components substances that can be detected with such a measurement, which can be excluded in the measurement cross sensitivities with other substances of the detergent and / or soiling on the items to be washed. The same applies to the measurement influencing interactions of substances with each other
Bspw. kann in einer bevorzugten Ausführungsform vorgesehen sein, dass die Absorptions- und/oder Reflexionsmessungen mit elektromagnetischer Strahlung im Wellenlängenbereich von Infrarotstrahlung, Ultraviolettstrahlung und/oder von sichtbarem Licht durchführbar sind. Dabei werden z.B. Messungen mit Infrarot- und/oder Ultraviolettstrahlung weniger stark von die optische Trübung beeinflussenden Inhaltstoffen beeinflusst. Um die Messgenauigkeit zu steigern kann vorgesehen sein, mehrere Messungen in unterschiedlichen Wellenlängenbereichen durchzuführen. Alternativ und/oder zusätzlich können weitere Messungen vorgesehen sein, wie z.B. die Messung der Leitfähigkeit, der Dielektrizität, der magnetischen Eigenschaften, von zusätzlich vorgesehen sein kann, deren Frequenzabhängigkeit im Rahmen von spektroskopischen Untersuchungen mit auszuwerten.For example. may be provided in a preferred embodiment that the absorption and / or reflection measurements with electromagnetic radiation in the wavelength range of infrared radiation, ultraviolet radiation and / or visible light can be performed.

In einer bevorzugten Ausführungsform ist vorgesehen, dass die Analyseeinheit wenigstens einen Trübungssensor umfasst. Mit dem Trübungssensor, der z.B. im Hydrauliksystem einer Geschirrspülmaschine angeordnet ist, in dem während des Betriebs u.a. Spülflotte, d.h. mit Reinigungsmitteln und/oder Anschmutzungen des Spülguts versetztes Wasser umgewälzt wird, kann ohne einen weiteren Sensor eine Reinigungsmittelidentifikation durchgeführt werden. Hierzu kann der Trübungssensor zur Durchführung einer Mehrzahl von Messungen ausgebildet, z.B. in verschiedenen Wellenlängenbereichen.In a preferred embodiment it is provided that the analysis unit comprises at least one turbidity sensor. With the turbidity sensor, e.g. is arranged in the hydraulic system of a dishwasher, in which u.a. Rinsing liquor, i. is circulated with cleaning agents and / or soiling of the dishes added water, a detergent identification can be performed without a further sensor. For this purpose, the turbidity sensor may be configured to perform a plurality of measurements, e.g. in different wavelength ranges.
Alternativ dazu kann die Analyseeinheit eine Leseeinheit aufweisen, die eine nach Art eines Barcodes auf das Reinigungsmittel oder auf dessen Verpackung aufgebrachte Markierungskomponente erfasst. Gegebenenfalls kann die Leseeinheit an einer Bedienblende des Haushaltsgeräts vorgesehen sein. In diesem Fall kann das insbesondere noch verpackte Reinigungsmittel an der Leseeinheit vorbeigeführt und identifiziert werden.Alternatively, the analysis unit may comprise a reading unit which detects a marking component applied to the cleaning agent or its packaging in the manner of a barcode. Optionally, the reading unit may be provided on a control panel of the household appliance. In this case, the particular still packaged cleaning agent can be guided past the reading unit and identified.
Das Identifizieren des Reinigungsmittels kann bevorzugt vollautomatisch erfolgen. Eine benutzerseitige Aktivierung, etwa durch Betätigung einer zusätzlichen Taste oder dergleichen, ist somit nicht erforderlich. Das Identifizieren der Stoffzusammensetzung des Reinigungsmittels sowie die Anpassung des Spülprogramms zur Durchführung des Spülganges kann daher bevorzugt unbemerkt vom Benutzer erfolgen.The identification of the cleaning agent can preferably take place fully automatically. A user-side activation, such as by pressing an additional button or the like, is thus not required. The identification of the substance composition of the cleaning agent as well as the adaptation of the rinsing program for carrying out the rinse cycle can therefore preferably take place unnoticed by the user.
In einer Ausführungsform kann das Reinigungsmittel herstellerseitig derart ausgestaltet sein, dass eine besonders einfache Identifizierung der für das Spülergebnis bedeutsamen Wirkstoffkomponenten ermöglicht ist. Insbesondere kann herstellerseitig eine entsprechende Markierungskomponente in das Reinigungsmittel eingebaut werden.In one embodiment, the cleaning agent may be designed by the manufacturer such that a particularly simple identification of the active ingredient components that are important for the rinsing result is made possible. In particular, a corresponding marking component can be incorporated into the detergent by the manufacturer.
Wie bereits oben erwähnt, kann bevorzugt das Haushaltsgerät zusammen mit dem zumindest einen Reinigungsmittel in einem System bereitgestellt werden, in welchem das Haushaltsgerät zusammen mit dem Reinigungsmittel so ausgelegt sind, dass die Analyseeinheit des Haushaltsgerätes betriebssicher die Stoffzusammensetzung des Reinigungsmittels identifizieren kann. Bevorzugt werden bei einer Anzahl von gegebenenfalls anwendbaren Reinigungsmitteln jeweils Markierungskomponenten eingebaut, auf deren Grundlage die Analyseeinheit des Haushaltsgerätes detaillierte Informationen über dem Hersteller und/oder über andere Leistungsmerkmale des verwendeten Reinigungsmittels erhalten kann.As already mentioned above, the household appliance together with the at least one cleaning agent can preferably be provided in a system in which the household appliance together with the cleaning agent are designed such that the analysis unit of the household appliance can reliably identify the substance composition of the cleaning agent. In each case, marking components are preferably incorporated in a number of optionally applicable cleaning agents, on the basis of which the analysis unit of the household appliance has detailed information about the manufacturer and / or other performance characteristics of the cleaning agent used.
