Abstract

In normal use a composite wash products tablet is employed and used up by the end of the normal programme cycle. The facility of adding an additional clear rinse is provided by a selection by which rinse aid material is dispensed from the door dispenser.

Description

Die Erfindung betrifft ein Verfahren zur Durchführung eines Klarspül-Programmabschnitts in einer programmgesteuerten Geschirrspülmaschine, bei welcher mit Bedienelementen Spülprogramme wählbar sind, wobei mindestens ein Spülprogramm an die Verwendung eines herkömmlichen Reinigers und eines aus einer Dosiereinrichtung zugeführten Klarspülers angepasst ist, und wobei mindestens ein weiteres Spülprogramm an die Verwendung eines Kombinationspräparates, das neben dem Reiniger mindestens Klarspülmittel enthält, angepasst ist.The invention relates to a method for carrying out a rinsing program section in a program-controlled dishwashing machine, wherein flushing programs can be selected with operating elements, wherein at least one washing program is adapted to the use of a conventional cleaner and a rinse aid supplied from a metering device, and wherein at least one further washing program to the use of a combination preparation containing in addition to the cleaner at least rinse aid adapted.

Geschirrspülmaschinen, welche sowohl für die Verwendung von herkömmlichen Reinigern als auch für Kombinationspräparate angepasst sind, sind aus der DE 100 49 489 A1, aus der DE 102 20 839 A1, aus der DE 102 30 567 A1 und aus der EP 1 362 547 A2 bekannt. Bei den Kombinationspräparaten handelt es sich um sogenannte "2in1"- und "3in1 "-Tabletten, welche neben dem Reinigungsmittel zusätzlich Klarspüler (2in1) oder Klarspüler und Regeneriersalzersatzstoffe (3in1) enthalten. Dabei arbeiten einige Präparate nach dem Carry-Over-Prinzip, bei dem sich bereits zu Beginn des Spülprogramms der Klarspüler in einer überdosierten Menge auflöst und wo dann die tatsächlich benötigte Menge durch Verschleppung und Adhäsion am Spülgut bis in den Klarspülgang gelangen soll. Bei anderen Präparaten ist der Klarspüler in Form einer wachsumhüllten Perle integriert, wobei sich das Wachs temperatur- oder pH-Wertabhängig erst im Klarspülgang auflösen und den Klarspüler freigeben soll. Die aus der DE 100 49 489 A1, aus der DE 102 20 839 A1 und aus der DE 102 30 567 A1 bekannten Geschirrspülmaschinen sind an die Verwendung solcher Präparate dadurch angepasst, dass Mittel zum Sperren der Klarspülerzufuhr aus der meist in der Gerätetür angeordneten Dosiervorrichtung vorhanden sind.Dishwashers, which are adapted both for the use of conventional cleaners and for combination preparations, are known from DE 100 49 489 A1, from DE 102 20 839 A1, from DE 102 30 567 A1 and from EP 1 362 547 A2 , The combination preparations are so-called "2in1" and "3in1" tablets, which in addition to the detergent also contain rinse aid (2in1) or rinse aid and regenerating salt substitutes (3in1). Some preparations work according to the carry-over principle, in which the rinse aid dissolves in an overdosed amount already at the beginning of the rinsing program and where then the actually required amount is to be transferred to the rinse cycle by carryover and adhesion to the items to be washed. In other preparations, the rinse aid is integrated in the form of a wax-coated bead, whereby the wax should dissolve depending on temperature or pH only in the rinse cycle and should release the rinse aid. The dishwashers known from DE 100 49 489 A1, from DE 102 20 839 A1 and from DE 102 30 567 A1 are adapted to the use of such preparations in that means for blocking the rinse aid supply from the usually arranged in the appliance door metering device available are.

In Programmen, in welchen bereits im Reinigungs-Programmabschnitt hohe Spülflüssigkeitstemperaturen herrschen, arbeiten die vorgenannten Präparate nicht zufriedenstellend, weil der in den Tabletten enthaltene Klarspüler bereits in der Spülflüssigkeit gelöst und am Ende des Programmabschnitts mit der Flüssigkeit entleert wird. Das Fehlen des Klarspülers im abschließenden Klarspül-Programmabschnitt verursacht deshalb ein schlechtes Trocknungsergebnis. Ein weiterer Nachteil entsteht bei den vorgenannten Geschirrspülmaschinen, wenn ausschließlich "2in1"- oder "3in1 "-Programme über einen längeren Zeitraum durchgeführt werden, was ja beim Kauf einer Vorratspackung der wahrscheinlichste Fall ist. Durch das langfristige Ausbleiben einer Dosierung von Klarspüler aus der Dosiereinrichtung kann deren Betätigungsmechanismus beschädigt werden, insbesondere können die zugehörigen Dichtungen verkleben. Außerdem kann in der Dosiereinrichtung vorhandener Klarspüler gelieren oder flockig werden.In programs in which high rinsing liquid temperatures already prevail in the cleaning program section, the abovementioned preparations do not work satisfactorily because the rinse aid contained in the tablets is already dissolved in the rinsing liquid and emptied with the liquid at the end of the program section. The absence of the rinse aid in the final rinse program section therefore causes a poor drying result. Another disadvantage arises in the aforementioned dishwashers, if only "2in1" or "3in1" programs are carried out over a longer period of time, which is the most likely case when buying a supply pack. Due to the long-term absence of a dosage of rinse aid from the metering device whose actuating mechanism can be damaged, in particular, the associated seals stick together. In addition, rinse aid present in the metering device can gel or become flaky.

Aus der EP 1 362 547 A2 ist es bekannt, bei einem "2in1"- oder "3in1"-Programm zu Beginn des Klarspül-Programmabschnitts die Klarspüler-Konzentration zu messen und abhängig vom Messergebnis Klarspüler nachzudosieren. Hierdurch kann zwar ein zufriedenstellendes Trocknungsergebnis sichergestellt werden, dies wird jedoch durch eine teure Sensorik erkauft. Außerdem werden die durch eine längerfristige Nichtbenutzung der Dosiereinrichtung entstehenden Nachteile nicht vermieden.From EP 1 362 547 A2 it is known to measure the rinse aid concentration in the case of a "2in1" or "3in1" program at the beginning of the rinse program section and to add rinse aid depending on the measurement result. Although this can ensure a satisfactory drying result, but this is paid for by an expensive sensor. In addition, the disadvantages resulting from a long-term non-use of the metering device are not avoided.

Der Erfindung stellt sich somit das Problem, ein Verfahren zur Durchführung eines Klarspül-Programmabschnitts in einer programmgesteuerten Geschirrspülmaschine der eingangs genannten Art zu offenbaren, bei welchem die vorbeschriebenen Nachteile verhindert und mit einfachen Mitteln ein zufriedenstellendes Trocknungsergebnis auch bei Verwendung eines "2in1"- oder "3in1 "-Reinigers erreicht wird.The invention thus presents the problem to disclose a method for carrying out a rinse program section in a program-controlled dishwasher of the type mentioned, in which prevents the disadvantages described above and with simple means a satisfactory drying result even when using a "2in1" - or " 3in1 "cleaner is achieved.

Erfindungsgemäß wird dieses Problem dadurch gelöst, dass im Klarspül-Programmabschnitt des Spülprogramms, welches an die Verwendung eines Kombinationspräparates, das neben dem Reiniger mindestens Klarspülmittel enthält, angepasst ist, zusätzlich eine festgelegte Menge Klarspüler aus der Dosiereinrichtung zugeführt wird, wobei die Menge geringer ist als die Menge Klarspüler, die bei einem Spülprogramm zugeführt wird, welches an die Verwendung eines herkömmlichen Reinigers und eines aus einer Dosiereinrichtung zugeführten Klarspülers angepasst ist.According to the invention, this problem is solved in that in the rinse program section of the washing program, which is adapted to the use of a combination preparation containing at least rinse aid in addition to the detergent, in addition a fixed amount of rinse aid from the metering device is supplied, wherein the amount is less than the amount of rinse aid supplied in a rinse program adapted for use with a conventional cleaner and a rinse aid supplied from a dosing device.

In einer vorteilhaften Ausführungsform des erfindungsgemäßen Verfahrens beträgt die festgelegte Menge zwischen 20% und 40% der Menge, die in einem Spülprogramm verwendet wird, welches an die Verwendung eines herkömmlichen Reinigers und eines aus einer Dosiereinrichtung zugeführten Klarspülers angepasst ist. Hierdurch wird nur wenig zusätzlicher Klarspüler verbraucht, welcher jedoch im Allgemeinen zur Ergänzung der im Kombinationspräparat vorhandenen Menge ausreicht.In an advantageous embodiment of the method according to the invention, the fixed amount is between 20% and 40% of the amount used in a rinse program adapted to the use of a conventional cleaner and a rinse aid supplied from a metering device. As a result, only a little additional rinse aid is consumed, which, however, is generally sufficient to supplement the amount present in the combination preparation.

Bei einem Verfahren zur Durchführung eines Spülprogramms, welches an die Verwendung eines Kombinationspräparates, das neben dem Reiniger mindestens Klarspülmittel enthält, angepasst ist, ist es besonders vorteilhaft, wenn während des Programmablaufs eine Einrichtung zur Anzeige eines Klarspülermangels in der Dosiereinrichtung deaktiviert ist. Hierdurch bleibt dem Benutzer freigestellt, ob er durch Auffüllen der Dosiereinrichtung mit Klarspüler die verbesserte Trocknungswirkung erreichen will oder ob er der Wirkung des Kombinationspräparates vertrauen will. In jedem Fall wird die Dosiereinrichtung vollständig von Klarspüler entleert.In a method for carrying out a washing program which is adapted to the use of a combination preparation which contains at least rinse aid in addition to the detergent, it is particularly advantageous if a device for displaying a rinse aid shortage in the metering device is deactivated during the program sequence. This leaves the user free to decide whether he wants to achieve the improved drying effect by filling the metering device with rinse aid or whether he wants to trust the effect of the combination preparation. In any case, the metering device is completely emptied of rinse aid.

Ein Ausführungsbeispiel des erfindungsgemäßen Verfahrens wird nachfolgend näher beschrieben. Eine Geschirrspülmaschine, mit deren Bedieneinrichtung sowohl "normale" Spülprogramme als auch "2in1 "- oder "3in1 "-Programme wählbar sind, ist aus der DE 102 20 839 A1 hinrei-. chend bekannt und wird deshalb nicht näher beschrieben. Der Standard-Programmablauf besteht bei einer solchen Geschirrspülmaschine aus den Programmabschnitten Vorspülen, Reinigen, Zwischenspülen, Klarspülen und Trocknen. Dabei können in einigen oder allen "2in1"- oder "3in1"-Programmen die Verfahrensparameter einzelner Programmabschnitte gegenüber denen von entsprechenden "Normal"-Programmen modifiziert und so an die entsprechenden Kombinationspräparate angepasst sein. Im Programmabschnitt Klarspülen erfolgt bei einem "Normal"-Programm zu Beginn eine Zugabe von ca. 3 ml Klarspüler aus einer in der Gerätetür angeordneten Dosiereinrichtung. Bei einem "2in1"- oder "3in1 "-Programm dagegen ist die Klarspülermenge, die aus der Dosiereinrichtung zugeführt wird, auf 1 ml festgelegt. Außerdem wird während der gesamten Durchführung solcher Programme die Klarspüler-Mangelanzeige deaktiviert.An embodiment of the method according to the invention will be described in more detail below. A dishwasher with whose operating device both "normal" washing programs and "2in1" or "3in1" programs can be selected is described in DE 102 20 839 A1. chend known and is therefore not described in detail. The standard program sequence consists in such a dishwasher from the program sections pre-rinsing, cleaning, intermediate rinsing, rinsing and drying. In some or all of the "2in1" or "3in1" programs, the process parameters of individual program sections can be modified from those of corresponding "normal" programs and thus adapted to the corresponding combination preparations. In the program section rinsing, in a "normal" program, at the beginning, an addition of about 3 ml of rinse aid takes place from a dosing device arranged in the appliance door. On the other hand, in a "2in1" or "3in1" program, the amount of rinse aid that is supplied from the metering device is set at 1 ml. In addition, throughout the implementation of such programs, the rinse aid deficiency indicator will be disabled.
