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 und neben der Verwendung von granulatförmigem Salz zum Enthärten des Wassers, das in einem speziellen Salzvorratsbehälter einer Enthärtungs- einrichtung mit einem Ionenaustauscher eingefüllt wird, sind seit einiger Zeit Mittel in tab- lettenförmiger oder gelförmiger Darreichungsform bekannt, welche nicht nur das eigentliche Spülmitte) 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 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 is introduced and dispensed from it at a predetermined time and in a predetermined amount, and 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, have been for some time agents have been known in tablet or gel form which not only contain the actual rinsing agent) but also those components which are required as consumables during a rinsing phase are dig. 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 dishwashing detergent additives - the rinse aid and a chemical that replaces the function of the softening device. According to the manufacturer of these tabs or gels, their respective components are used at precisely the point in time during the washing program when these components develop their optimal 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 Här- tegrad 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.When using tabs or gels with a corresponding chemical that replaces the function of the softening device, the disadvantage arises that the amount of chemicals in the tabs or gels is not matched to all water hardness levels, so that the use of tabs is regional in each case or gels either reduce the degree of hardness too much or do not reduce the degree of hardness sufficiently. In particular, the use of water with insufficiently reduced water hardness leads to a lower effectiveness of the detergent and rinse aid results in a significantly deteriorated cleaning and 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 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 von Salz und bei einer ausgeschalteten Enthärtungseinrichtung und bei Betrieb der Geschirrspülmaschine der Spülprogrammablauf angepasst. Durch die Salzmangelfeststellung in Verbindung mit einer ausgeschalteten Enthärtungseinrichtung und mit dem Betrieb der Geschirrspülmaschine kann zweifelsfrei 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, if the absence of salt is found and the softening device is switched off and the dishwasher is operating, the washing program sequence is adapted. The salt deficiency detection in connection with a deactivated softening device and with the operation of the dishwasher can undoubtedly determine the use of tabs or gels, for which, according to the invention, an adaptation of the washing program is provided without user intervention in order to achieve a satisfactory cleaning and drying performance.
Nach einem bevorzugten Merkmal der Erfindung wird während des Spülprogramms die Enthärtungseinrichtung trotz ausgeschaltetem Zustand zur Enthärtung des Wassers in Betrieb genommen wird und dass gegebenenfalls eine Salzmangelanzeige trotz ausgeschaltetem Zustand in Betrieb genommen. Durch die damit 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 dem Benutzer den Sonderfall in der Reinigungshandlung an.According to a preferred feature of the invention, the softening device is put into operation for the softening of the water despite the switched-off state during the rinsing program and that, if appropriate, a salt deficiency indicator is put into operation despite the switched off state. The resulting use of softened water for cleaning and rinsing results in a better effectiveness this addition means reached. The salt deficiency indicator, which was put into operation despite being switched off, shows the user the special case in the cleaning action.
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 von Salz mittels eines zu geringen Füllstandes an Salz in einem Salzvorratsbehälter festgestellt. Damit wird ein üblicherweise ohnehin vor- handener Sensor für eine weitere vorteilhafte Maßnahme verwendet.The absence of salt is expediently ascertained by means of an insufficient fill level of salt in a salt storage container. Thus, a sensor that is usually present anyway 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 enthärte- tes 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 washing liquor. In addition to the higher degree of hardness, non-softened water also has a different pH value than softened water. Therefore, the sensor for measuring the properties of the washing 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 vorteil- hafter 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 a sensor of this type, 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 absence of salt is found during the washing program, the softening device is started up to a minimum value in accordance with the determined pH value despite the switched-off state for softening the water and, if appropriate, a salt deficiency indicator is put into operation despite the switched-off state. Since it is known that the chemical contained in the tabs or gels, which is intended to replace the function of the softening device, has an effect of up to approximately 25 ° dH, the minimum degree of hardness is intended to be approximately 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. 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. The above-mentioned object is achieved by a dishwasher according to the invention for using a method according to one of the preceding claims, wherein a pH value sensor or a water hardness sensor is advantageously arranged for measuring the properties of the washing liquor.
