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 und neben der Verwendung von granulatförmigem Salz zum Enthärten des Wassers, das in einem speziellen Salzvorratsbehälter einer Enthärtungseinrichtung mit einem Ionenaustauscher eingefüllt wird, sind seit einiger Zeit Mittel in tablettenförmiger oder gelförmiger 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 "3 in 1 Tabs" oder "3 in 1 Gels" bekannt, die neben dem Geschirrspülmittel auch die unterschiedlichen Spülmittelzusätze - den Klarspüler und eine Chemikalie, die die Funktion der Enthärtungseinrichtung ersetzt, 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 For some time, in addition to the use of granular salt for softening the water, which is filled in a special salt reservoir of a softening device with an ion exchanger, means in tablet-like or gel-containing dosage form containing not only the actual rinse but also those ingredients that are necessary as consumables during a rinse phase , Thus, for example, combination products, so-called "3 in 1 tabs" or "3 in 1 gels" have been known for some time, which in addition to the dishwashing detergent also contain the different rinse aid additives - the rinse aid and a chemical which replaces the function of the softening device. 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.

Bei der Verwendung von Tabs oder Gels mit einer entsprechenden Chemikalie, die die Funktion der Enthärtungseinrichtung ersetzt, tritt der Nachteil auf, dass die in den Tabs oder Gels befindliche Chemikalienmenge nicht auf alle Wasserhärtegrade abgestimmt ist, so dass jeweils regional bedingt, die Verwendung von Tabs oder Gels entweder den Härtegrad zu sehr reduziert oder den Härtegrad nicht ausreichend reduziert. Insbesondere die Verwendung von Wasser mit nicht ausreichend reduzierter Wasserhärte führt zu einer geringeren Wirksamkeit des Spülmittels und des Klarspülmittels ergibt dadurch ein wesentlich verschlechtertes Reinigungs- und Trocknungsergebnis.The use of tabs or gels with a corresponding chemical that replaces the function of the water softener, the disadvantage occurs that the amount of chemicals in the tabs or gels is not adjusted to all degrees of water hardness, so that, depending on the region, the use of tabs or gels either too much reduced the degree of hardness or not sufficiently reduced the degree of hardness. In particular, the use of water with insufficiently reduced water hardness leads to a lower effectiveness of the rinsing agent and the rinse aid thereby results in a significantly deteriorated cleaning and drying 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 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 der DE 35 33 098 A1 ist eine Vorrichtung zum Enthärten von Wasser beschrieben. Am Zulauf und/oder am im Auslauf eines Behälters mit lonenaustauschermasse sind Sensoren angeordnet, welche gegen das Regeneriermittel sensibel sind. Aus dem Unterschied der Leitfähigkeit des am Zulauf eintretenden Wassers und am Auslauf austretenden Wassers kann auf ein ausreichendes Regenerieren geschlossen werden und der Regeneriervorgang beendet werden. Außerdem kann mit den Sensoren, welche am Eingang des Behälters mit lonenaustauschermasse, direkt im Regeneriermittel-Behälter oder in der Verbindungsleitung zwischen dem Behälter und Behälter angeordnet sind, geprüft werden, ob überhaupt noch Salzlösung mit entsprechender Konzentration vorhanden ist. Diese Salzanzeige kann dazu benutzt werden, das Programm auszusetzen oder den Regeneriervorgang zu überbrücken.From the DE 35 33 098 A1 a device for softening water is described. At the inlet and / or at the outlet of a container with ion exchanger mass sensors are arranged, which are sensitive to the regenerating agent. From the difference in the conductivity of the water entering at the inlet and water leaving the outlet, sufficient regeneration can be concluded and the regeneration process can be ended. In addition, it can be checked with the sensors, which are arranged at the entrance of the container with ion exchange material, directly in the regenerant container or in the connecting line between the container and container, if any saline solution of appropriate concentration is present. This salt indicator can be used to suspend the program or to bypass the regeneration process.

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 so that a satisfactory cleaning and drying performance is achieved even when using combination detergent.

Diese Aufgabe wird durch das erfindungsgemäße Verfahren mit den Merkmalen gemäß Anspruch 1 und durch eine Geschirrspülmaschine mit den Merkmalen des Anspruchs 9 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 a dishwasher with the features of claim 9. Advantageous developments of the inventions are characterized in the subclaims.

Bei dem erfindungsgemäßen Verfahren zum Anpassen eines Spülprogramms in einer Geschirrspülmaschine wird bei Verwendung von Kombinationsspülmittel, wie etwa Tabs oder Gel, bei Feststellung des Fehlens von Salz und bei ausgeschalteter Enthärtungseinrichtung und bei Betrieb der Geschirrspülmaschine die Benutzung von Tabs oder Gel festgestellt und der Spülprogrammablauf ohne Einwirkung des Benutzers angepasst, wobei die Enthärtungseinrichtung trotz ausgeschaltetem Zustand zur Enthärtung des Wassers in Betrieb genommen wird. Dadurch erfolgt eine Anpassung an die Verwendung des Tabs oder Gels. Durch die Salzmangelfeststellung in Verbindung mit einer ausgeschalteten Enthärtungseinrichtung und mit dem Betrieb der Geschirrspülmaschine kann die Benutzung von Tabs oder Gels festgestellt werden, wofür nach der Erfindung zum Erreichen einer befriedigende Reinigungs- und Trocknungsleistung eine Anpassung des Spülprogramms ohne Einwirkung des Benutzers vorgesehen ist.In the method according to the invention for adapting a washing program in a dishwasher, the use of combination detergents, such as tabs or Gel, found on detection of the absence of salt and the softening device is switched off and the operation of the dishwasher, the use of tabs or gel and the Spülprogrammablauf adjusted without user intervention, the softener is switched off despite the state for softening the water in operation. This will adapt to the use of the tab or gel. Due to the salt deficiency detection in conjunction with a switched off softening device and with the operation of the dishwasher, the use of tabs or gels can be determined, for which according to the invention to achieve a satisfactory cleaning and drying performance adjustment of the washing program is provided without user intervention.

Nach einem bevorzugten Merkmal der Erfindung wird während des Spülprogramms eine Salzmangelanzeige trotz ausgeschaltetem Zustand der Enthärtungseinrichtung in Betrieb genommen.According to a preferred feature of the invention, a lack of salt is put into operation despite the state of the softening device during the wash program.

Durch die mit der Erfindung ermöglichte Verwendung von enthärtetem Wasser zur Reinigung und zum Klarspülen wird eine bessere Wirksamkeit dieser Zugabemittel erreicht. Die trotz ausgeschaltetem Zustand in Betrieb genommene Salzmangelanzeige zeigt vorteilhaft dem Benutzer den Sonderfall in der Reinigungshandlung an.The use of softened water for cleaning and rinsing, made possible by the invention, achieves better effectiveness of this additive. The salt deficient indicator put into operation despite being switched off advantageously indicates to the user the special case in the cleaning act.

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.

Zweckmäßigerweise wird das Fehlen von Salz mittels eines zu geringen Füllstandes an Salz in einem Salzvorratsbehälter festgestellt. Damit wird ein üblicherweise ohnehin vorhandener Sensor für eine weitere vorteilhafte Maßnahme verwendet.Conveniently, the absence of salt is detected by means of too low a level of salt in a salt reservoir. Thus, a commonly used anyway sensor is used for a further advantageous measure.

Nach einer vorteilhaften Ausführungsform der Erfindung wird das Fehlen von Salz mittels eines Sensors zur Messung der Eigenschaften der Spülflotte festgestellt. Nicht enthärtetes Wasser hat außer dem höheren Härtegrad auch einen anderen ph-Wert als enthärtetes Wasser. Daher ist vorteilhafterweise der Sensor zur Messung der Eigenschaften der Spülflotte ein ph-Wert-Sensor oder ein Wasserhärte-Sensor.According to an advantageous embodiment of the invention, the absence of salt is determined by means of a sensor for measuring the properties of the rinsing liquor. Non-softened water also has a different pH than softened water, in addition to the higher degree of hardness. Therefore, the sensor for measuring the properties of the wash liquor is advantageously a ph value sensor or a water hardness sensor.

Mit einem derartigen Sensor kann bei einem Vergleich mit einem vorgegebenen Wert die Resthärte des eingefüllten Wassers festgestellt werden. Daher wird in besonders vorteilhafter Weise bei Feststellung des Fehlens von Salz während des Spülprogramms die Enthärtungseinrichtung trotz ausgeschaltetem Zustand zur Enthärtung des Wassers entsprechend des festgestellten ph-Wertes auf einen Mindestwert in Betrieb genommen und gegebenenfalls eine Salzmangelanzeige trotz ausgeschaltetem Zustand in Betrieb genommen. Da bekannt ist, dass die in den Tabs oder Gels enthaltene Chemikalie, die die Funktion der Enthärtungseinrichtung ersetzen soll bis etwa 25 °dH wirkt, beträgt bestimmungsgemäß der Mindesthärtegrad etwa 25° dH.With such a sensor, the residual hardness of the filled water can be determined in a comparison with a predetermined value. Therefore, in a particularly advantageous manner, if the salt is not detected during the wash program, the water softener, despite being switched off, starts operating at a minimum value to soften the water in accordance with the determined pH and, if necessary, puts a salt deficient indicator into operation, despite being switched off. Since it is known that the chemical contained in the tabs or gels, which should replace the function of the softening device acts up to about 25 ° dH, the minimum degree of hardness is intended to be about 25 ° dH.

Die oben genannte Aufgabe wird durch eine erfindungsgemäße Geschirrspülmaschine zur Verwendung eines Verfahrens nach einem der vorherigen Ansprüche gelöst, wobei vorteilhafterweise ein ph-Wert-Sensor oder ein Wasserhärte-Sensor zur Messung der Eigenschaften der Spülflotte angeordnet ist.The above object is achieved by a dishwasher according to the invention for use of a method according to one of the preceding claims, wherein advantageously a ph-value sensor or a water hardness sensor for measuring the properties of the rinsing 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.
