Description

Die Erfindung betrifft ein Verfahren zum Anpassen eines Spülprogramms in einer Geschirrspülmaschine sowie eine Geschirrspülmaschine zur Verwendung dieses Verfahrens.The invention relates to a method for adjusting a washing program in a dishwasher and a dishwasher for using this method.

Neben der herkömmlichen Verwendung von Geschirrspülmittel, welches in Pulverform vorliegt und in eine zumeist in der Tür einer Geschirrspülmaschine befindlichen Spülmittelabgabevorrichtung eingebracht und von dieser zu einem vorbestimmten Zeitpunkt ausgebracht wird und neben der Verwendung von flüssigem Klarspüler, der ebenfalls in eine zumeist in der Tür einer Geschirrspülmaschine befindlichen Spülmittelabgabevorrichtung eingebracht und von dieser zu einem vorbestimmten Zeitpunkt und in einer vorbestimmten Menge ausgebracht wird, sind seit einiger Zeit Mittel in tablettenförmiger Darreichungsform bekannt, welche nicht nur das eigentliche Spülmittel sondern auch diejenigen Bestandteile enthalten, die als Verbrauchsstoffe während einer Spülphase notwendig sind. So sind beispielsweise seit einiger Zeit Kombinationsprodukte, sogenannte ,,2 in 1 Tabs" oder "2 in 1 Gels" und "3 in 1 Tabs" oder ,,3 in 1 Gels" bekannt, die neben dem Geschirrspülmittel wenigstens auch den Klarspüler beinhalten. Nach der Vorstellung der Hersteller dieser Tabs oder Gels finden deren jeweiligen Bestandteile genau zu dem Zeitpunkt während des Spülprogrammablaufs Einsatz, an dem diese Bestandteile ihre optimale Wirkung entfalten.In addition to the conventional use of dishwashing detergent, which is in powder form and is introduced into a dishwashing machine dispensing device and dispensed therefrom at a predetermined time and in addition to the use of liquid rinse aid, which is also usually in the door of a dishwasher Present detergent dispenser and introduced therefrom at a predetermined time and in a predetermined amount, have been known for some time means in tablet form, which contain not only the actual detergent but also those ingredients that are necessary as consumables during a rinsing phase. Thus, for example, combination products, so-called "2 in 1 tabs" or "2 in 1 gels" and "3 in 1 tabs" or "3 in 1 gels" have been known for some time and, in addition to the dishwashing agent, also contain at least the rinse aid. Following the presentation of the manufacturers of these tabs or gels, their respective ingredients find application at exactly the time during the rinse cycle where these ingredients perform to their optimum effect.

Da jedoch der Spülprogrammablauf sowohl von dem jeweils gewählten Spülprogramm, dem Hersteller der Geschirrspülmaschine als auch von einzelnen Modelltypen abhängt, kann der Einsatz von Tabs oder Gels dazu führen, dass beispielsweise der Klarspüler zu einem Zeitpunkt in die Spülflotte freigegeben wird, an dem noch kein Klarspülen stattfindet, so dass in einem tatsächlichen Teilprogrammabschnitt Klarspülen kein entsprechender Klarspüler mehr vorhanden ist. Denn bei einigen bekannten Tabs oder Gels ist die Freigabe des Klarspülers lediglich an die Umgebungstemperatur erkoppelt, so dass bei Überschreiten dieser Temperatur bereits während eines Teilprogrammabschnitts Reinigen, Klarspüler freigesetzt wird.However, since the wash program sequence depends on both the selected wash program, the manufacturer of the dishwasher as well as individual model types, the use of tabs or gels can cause, for example, the rinse aid is released at a time in the wash liquor, at which no rinsing takes place, so that in an actual part program section rinsing no corresponding rinse aid is no longer available. Because in some known tabs or gels the release of the rinse aid is only coupled to the ambient temperature, so that when this temperature is exceeded even during a partial program section cleaning, rinse aid is released.

Bei einer anderen Ausgestaltung des Spülprogramms kann es sein, dass der Klarspüler nicht aktiviert wird, so dass ebenfalls keine Klarspülwirkung erzielt wird, wobei jedoch der Klarspüler nach Abschluss des Spülprogramms beispielsweise immer noch in unaufgelöster Form vorliegt.In another embodiment of the wash program, it may be that the rinse aid is not activated, so that also no rinse effect is achieved, but the rinse aid after completion of the wash program, for example, still in unresolved form.

Da der Klarspüler üblicherweise vor allem die Funktion des Abbaus der Oberflächenspannung der Klarspülflotte hat, führt das Fehlen des Klarspülers in der Klarspülflotte zu einem verringerten Abfließen des auf dem zu reinigenden Gutes verbliebenen Restwassers im Teilprogrammabschnitt Trocknen, was gegenüber der Verwendung einer Klarspülflotte mit Klarspüleranteil ein wesentlich verschlechtertes Trocknungsergebnis ergibt.Since the rinse aid usually has the function of degrading the surface tension of the rinse aid, the absence of the rinse aid in the rinse liquor leads to a reduced outflow of residual water left on the item to be cleaned in the drying subprogram, which is a significant factor compared to the use of rinse aid liquor with rinse aid portion results in a deteriorated drying result.

Als Folge dieser Verwendung der Tabs oder Gels kann der Benutzer der Geschirrspülmaschine feststellen, dass die Reinigungsleistung und/oder die Trocknungsleistung nicht befriedigend ist und führt dieses Ergebnis in vielen Fällen ursächlich auf die Geschirrspülmaschine zurück, obwohl die Ursache hauptsächlich in der Verwendung der Tabs oder Gels liegt.As a result of this use of the tabs or gels, the user of the dishwasher may find that the cleaning performance and / or the drying performance is not satisfactory and in many cases causes this result on the dishwasher, although the cause is mainly due to the use of tabs or gels lies.

Aus DE 196 50 915 ist ein Verfahren bekannt, bei dem das Fehlens der Zugabe eines Klarspülmittels bei einer Geschirrspülmaschine mit Hilfe eines Sensors erkannt wird, der die Leitfähigkeit der Spülflüssigkeit bestimmt. Als Reaktion auf eine fehlende Zugabe wird das Spülprogramm unterbrochen. In US 5,806, 541 A ist eine Geschirrspülmaschine bekannt, bei der im Klarspülschritt bei fehlender Zugabe von Klarspülmittel, was mit einem Trübesensors festgestellt wird, die Betriebsdauer eines zur Geschirrtrocknung vorhandenes Gebläses verlängert wird.Out DE 196 50 915 a method is known in which the absence of the addition of a rinse aid in a dishwasher is detected by means of a sensor which determines the conductivity of the rinsing liquid. In response to a lack of addition, the washing program is interrupted. In US 5,806,541A a dishwashing machine is known in which in the rinse step in the absence of addition of rinse aid, which is determined with a turbidity sensor, the service life of a present for drying the dishwasher fan is extended.

Aufgabe der vorliegenden Erfindung ist es, ein Verfahren bereitzustellen, welches es erlaubt den Spülprogrammablauf einer Geschirrspülmaschine so anzupassen, dass auch bei Verwendung von Kombinationsspülmittel eine befriedigende Reinigungs- und Trocknungsleistung erzielt wird.Object of the present invention is to provide a method which allows the Spülprogrammablauf a dishwasher to be adjusted so that even when using combination detergent a satisfactory cleaning and drying performance is achieved.

Diese Aufgabe wird durch das erfindungsgemäße Verfahren mit den Merkmalen gemäß Anspruch 1 und durch die Geschirrspülmaschine mit den Merkmalen gemäß des weiteren unabhängigen Anspruchs gelöst. Vorteilhafte Weiterbildungen der Erfindungen sind in den Unteransprüchen gekennzeichnet.This object is achieved by the method according to the invention with the features according to claim 1 and by the dishwasher with the features according to the further independent claim. Advantageous developments of the inventions are characterized in the subclaims.

Bei dem erfindungsgemäßen Verfahren zum Anpassen eines Spülprogramms in einer Geschirrspülmaschine wird bei Feststellung des Fehlens der Zugabe von Klarspülmittel und bei Betrieb der Geschirrspülmaschine der Spülprogrammablauf angepasst. Durch die Klarspülermangelfeststellung in Verbindung mit dem Betrieb der Geschirrspülmaschine wird festgestellt, dass entweder der Benutzer vergessen hat Klarspüler einzufüllen oder dass die beschriebenen Tabs oder Gels verwendet werden. In beiden Fällen ist nach der Erfindung zum Erreichen einer befriedigenden Reinigungs- und Trocknungsleistung eine Anpassung des Spülprogramms ohne Einwirkung des Benutzers vorgesehen.In the method according to the invention for adapting a wash program in a dishwasher, the washing program sequence is adjusted when the absence of the addition of rinse aid and during operation of the dishwasher are detected. The rinse aid failure detection associated with the operation of the dishwasher determines that either the user has forgotten to load rinse aid or that the tabs or gels described are being used. In both cases, an adaptation of the washing program is provided without the action of the user according to the invention to achieve a satisfactory cleaning and drying performance.

Nach einem bevorzugten Merkmal der Erfindung wird bei Feststellung des Fehlens der Zugabe von Klarspülmittel und bei Betrieb der Geschirrspülmaschine während des Spülprogramms die Anzahl der Flottenwechsel in einem Teilprogrammschritt Zwischenspülen gesenkt und/oder die Anzahl der Flottenwechsel in einem Teilprogrammschritt Klarspülen und/oder die Dauer eines Teilprogrammschrittes Trocknen und/oder die damit verbundene Temperatur erhöht. Eine gesenkte Anzahl der Flottenwechsel im Teilprogrammschritt Zwischenspülen, was üblicherweise mit Klarwasser betrieben wird, ermöglicht eine Weiterverwendung der Reinigungsflotte im Klarspülen, wodurch dann - bei Bedarf - diese "verschleppte" Flotte die Klarspülfunktionen übernehmen kann. Eine erhöhte Temperatur der Klarspülflotte, insbesondere im Klarspülen, ermöglicht ein besseres Verdampfen der auf dem mit der Klarspülflotte erwärmten zu reinigenden Gutes verbliebenen Restflüssigkeit und ermöglicht somit ein ausreichendes Trocknungsergebnis. Zur ausreichenden Erwärmung und zur ausreichenden Restreinigung des zu reinigenden Gutes dient auch eine Verlängerung des Klarspülens. Die Erhöhung der Temperatur im Klarspülen bewirkt natürlich auch eine erhöhte Temperatur im Trocknen, wobei dessen Verlängerung ein besseres Verdampfen der Restflüssigkeit gewährleistet.According to a preferred feature of the invention, when the absence of the addition of rinse aid and during operation of the dishwasher during the wash program, the number of liquor changes in a subprogram step reduces intermediate rinsing and / or the number of liquor changes in a partial program step rinsing and / or the duration of a partial program step Drying and / or the associated temperature increases. A reduced number of liquor changes in the sub-program step intermediate rinsing, which is usually operated with clear water, allows further use of the cleaning liquor in rinsing, which then - if necessary - this "abducted" liquor can take over the rinsing functions. An elevated temperature of the rinse aid liquor, in particular in rinse-off, makes it possible to evaporate the residual liquid remaining on the product to be cleaned which has been heated with the rinse aid liquor and thus allows a sufficient drying result. For adequate heating and sufficient residual cleaning of the material to be cleaned also serves to extend the rinse. The increase in the temperature in the rinse, of course, also causes an increased temperature in the drying, the extension of which ensures a better evaporation of the residual liquid.

Mit der vorliegenden Erfindung ist es gelungen, ein Verfahren bereitzustellen, welches es erlaubt, den Spülprogrammablauf einer Geschirrspülmaschine so anzupassen, dass auch bei Verwendung von Kombinationsspülmittel eine befriedigende Reinigungs- und Trocknungsleistung erzielt wird.With the present invention, it has been possible to provide a method which makes it possible to adapt the washing program sequence of a dishwasher so that a satisfactory cleaning and drying performance is achieved even when using combination detergent.

Das Fehlen der Zugabe von Klarspülmittel wird mittels eines Sensors zur Messung der chemischen Eigenschaften der Klarspülflotte festgestellt. Die Klarspülflotte ist bei Zugabe von Klarspüler im Gegensatz zu der laugenförmigen Reinigerflotte sauer, daher ist erfindungsgemäß der Sensor zur Messung der Eigenschaften der Klarspülflotte ein ph-Wert-Sensor.The absence of the addition of rinse aid is determined by means of a sensor for measuring the chemical properties of the rinse aid liquor. The rinse liquor is on addition of rinse aid, in contrast to the caustic cleaner liquor acidic, therefore, the sensor for measuring the properties of the rinse aid according to the invention is a ph-value sensor.

Mit einem derartigen Sensor kann bei einem Vergleich mit einem vorgegebenen Wert auch die Konzentration ev. doch noch vorhandenen Klarspülers in der Klarspülflotte festgestellt werden. Daher wird in besonders vorteilhafter Weise während des Spülprogramms die Anzahl der Flottenwechsel in einem Teilprogrammschritt Zwischenspülen und/oder Klarspülen und/oder die Dauer eines Teilprogrammschrittes Trocknen und/oder die damit verbundene Temperatur entsprechend des festgestellten ph-Wertes angepasst.With a sensor of this kind, the concentration of still present rinse aid in the rinse aid liquor can also be determined when compared with a predetermined value. Therefore, in a particularly advantageous manner during the wash program, the number of liquor changes in a partial program step intermediate rinsing and / or rinsing and / or the duration of a partial program step drying and / or the associated temperature adjusted according to the determined ph value.

Die oben genannte Aufgabe wird durch eine erfindungsgemäße Geschirrspülmaschine zur Verwendung eines Verfahrens nach einem der vorherigen Ansprüche gelöst. Dabei ist ein ph-Wert-Sensor zur Messung der Eigenschaften der Klarspülflotte angeordnet.The above object is achieved by a dishwasher according to the invention for use of a method according to one of the preceding claims. In this case, a ph value sensor for measuring the properties of the rinse aid liquor is arranged.

Mit der vorliegenden Erfindung ist es gelungen, ein Verfahren bereitzustellen, welches es erlaubt, den Spülprogrammablauf einer Geschirrspülmaschine so anzupassen, dass auch bei Verwendung von Kombinationsspülmittel eine befriedigende Reinigungs- und Trocknungsleistung erzielt wird.With the present invention, it has been possible to provide a method which makes it possible to adapt the washing program sequence of a dishwasher so that a satisfactory cleaning and drying performance is achieved even when using combination detergent.
