Description

Verfahren zum Anpassen eines Spülprogramms in einer Geschirrspülmaschine und Geschirrspülmaschine Method for adapting a washing program in a dishwasher and dishwasher
Die Erfindung betrifft ein Verfahren zum Anpassen eines Spülprogramms in einer Ge- schirrspülmaschine sowie eine Geschirrspülmaschine zur Verwendung dieses Verfahrens.The invention relates to a method for adapting 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 Spülmit- telabgabevorrichtung eingebracht und von dieser zu einem vorbestimmten Zeitpunkt aus- gebracht 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 Zeit- punkt 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 detergent dispensing device, which is usually located in the door of a dishwasher, and is dispensed by the latter at a predetermined point in time, and in addition to the use of liquid rinse aid, which is also in a mostly in Detergent dispenser located in the door of a dishwasher and dispensed by it at a predetermined time and in a predetermined amount have been known for some time in tablet form which not only contain the actual detergent but also those components which are consumable during a washing phase are necessary. 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, which in addition to the dishwashing detergent also contain at least the rinse aid. According to the manufacturer of these tabs or gels, their respective components are used at exactly the point in time during the washing program when these components develop their optimal 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. 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.However, since the wash program sequence depends on the selected wash program, the manufacturer of the dishwasher as well as on individual model types, the use of tabs or gels can lead to the rinse aid being released into the wash liquor, for example, at a time when there is still no rinse takes place, so that in an actual sub-program section rinse aid no corresponding rinse aid is available. With 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, the rinse aid is released during a part of the cleaning program. In another embodiment of the washing program, the rinse aid may not be activated, so that no rinse aid is obtained either, although the rinse aid, for example, is still in an unresolved form after the end of the washing program.
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 primarily has the function of reducing the surface tension of the rinse aid liquor, the absence of the rinse aid in the rinse aid liquor leads to a reduced drainage of the residual water remaining on the items to be cleaned in the drying sub-program section, which is a significant factor compared to the use of a rinse aid liquor with a rinse aid portion deteriorated drying result results.
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 can determine that the cleaning performance and / or the drying performance is unsatisfactory and in many cases attributes this result to the dishwasher, although the cause is mainly due to the use of the tabs or gels lies.
Aufgabe der vorliegenden Erfindung ist es daher, 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.The object of the present invention is therefore to provide a method which makes it possible to adapt the washing program sequence of a dishwasher in such a way that a satisfactory cleaning and drying performance is achieved even when using combination detergents.
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 befriedigende Reinigungs- und Trocknungsleistung eine Anpassung des Spülprogramms ohne Einwirkung des Benutzers vorgesehen.In the method according to the invention for adapting a washing program in a dishwasher, if the addition of rinse aid is not found and the dishwasher is operating, the washing program sequence is adapted. The lack of rinse aid in connection with the operation of the dishwasher determines that either the user has forgotten to add rinse aid or that the tabs or gels described are used. In both cases, after Invention to achieve a satisfactory cleaning and drying performance provided an adaptation of the washing program without user intervention.
Nach einem bevorzugten Merkmal der Erfindung wird bei Feststellung des Fehlens der Zugabe von Klarspülmittel und bei Betrieb der Geschirrspülmaschine während des Spül- Programms 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 Wei- terverwendung 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 Er- wärmung 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, the number of liquor changes in a sub-program step intermediate rinsing and / or the number of liquor changes in a sub-program step rinse and / or the duration is reduced if the addition of rinse aid and the dishwasher are detected during the washing program a sub-program step drying and / or the associated temperature is increased. A reduced number of liquor changes in the intermediate rinse sub-program step, which is usually operated with clear water, enables the cleaning liquor to continue to be used in the final rinse, so that - if necessary - this “carried over” liquor can take over the rinse aid functions Rinse-off enables better evaporation of the residual liquid remaining on the items to be cleaned, which have been warmed up with the rinse-aid liquor, and thus enables a sufficient drying result. For sufficient heating and sufficient residual cleaning of the items to be cleaned, an extension of the rinse-off also serves Rinse aid naturally also results in an increased temperature in the drying process, the extension of which ensures 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 in such a way that a satisfactory cleaning and drying performance is achieved even when using combination detergents.
Zweckmäßigerweise wird das Fehlen der Zugabe von Klarspülmittel mittels eines zu geringen Füllstandes an Klarspülmittel in einem Klarspülmittelvorratsbehälter festgestellt. Damit wird ein üblicherweise ohnehin vorhandener Sensor f ür eine weitere vorteilhafte Maßnahme verwendet.The absence of the addition of rinse aid is expediently determined by means of an insufficient rinse aid level in a rinse aid reservoir. Thus, a sensor that is usually present anyway is used for a further advantageous measure.
Nach einer vorteilhaften Ausführungsform der Erfindung wird das Fehlen der Zugabe von Klarspülmittel 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 vorteilhafterweise der Sensor zur Messung der Eigenschaften der Klarspülflotte ein ph-Wert-Sensor.According to an advantageous embodiment of the invention, the lack of rinse aid addition is determined by means of a sensor for measuring the chemical properties of the rinse aid liquor. The rinse aid liquor is in contrast when rinse aid is added acidic to the alkaline detergent liquor, therefore the sensor for measuring the properties of the rinse aid liquor is advantageously a pH value sensor.
Mit einem derartigen Sensor kann bei einem Vergleich mit einem vorgegebenen W ert auch die Konzentration ev. doch noch vorhandenen Klarspülers in der Klarspülflotte fest- gestellt 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 type, the concentration of any rinse aid still present in the rinse aid liquor can also be determined in a comparison with a predetermined value. Therefore, the number of liquor changes in a sub-program step intermediate rinsing and / or rinsing and / or the duration of a sub-program step drying and / or the temperature associated therewith is adjusted in a particularly advantageous manner during the rinsing program in accordance with the determined pH value.
Die oben genannte Aufgabe wird durch eine erfindungsgemäße Geschirrspülmaschine zur Verwendung eines Verfahrens nach einem der vorherigen Ansprüche gelöst.The above-mentioned object is achieved by an inventive dishwasher for using a method according to one of the preceding claims.
Nach einer vorteilhaften Ausführungsform der Erfindung ist ein ph-Wert-Sensor zur Messung der Eigenschaften der Klarspülflotte angeordnet.According to an advantageous embodiment of the invention, a pH value sensor is arranged for measuring the properties of the rinse aid liquor.
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 in such a way that a satisfactory cleaning and drying performance is achieved even when using combination detergents.
