Verfahren zum Reinigen von Geschirr in einer Haushai tgesch irr spülmaschineMethod for cleaning dishes in a domestic dishwasher

Die Erfindung bezieht sich auf ein Verfahren zum Reinigen von Geschirr nach dem Oberbegriff des Patentanspruches.The invention relates to a method for cleaning dishes according to the preamble of the patent claim.

Bei einer bekannten Geschirrspülmaschine (DE-OS 1 642 497) mit einem Spülbehälter, einem Ionenaustauscher sowie einer Frischwasserzuleitung zum Spülbehälter und einer Weichwasserzuleitung aus dem Ionenaustauscher zum Spülbehälter wird das Spül— und Waschwasser teilweise oder ganz enthärtet. Damit im enthärteten Spülwasser eine Resthärte vonIn a known dishwasher (DE-OS 1 642 497) with a washing container, an ion exchanger and a Fresh water supply to the rinsing tank and a soft water supply from the ion exchanger to the rinsing tank the rinsing and washing water is partially or completely softened. This means that there is a residual hardness of in the softened rinsing water

There is one rule the residual hardness by adapting to the locally different degrees of water hardness is not possible.

Aufgabe der .-Erfindung ist es, ein Verfahren zum Reinigen von Geschirr in einer Haushaltgeschirröpülntaschine der eingangs genannten Art anzugeben, das auf einfache Weise eine Einstellung der Resthärte der Reinigungsflüssigkeit unter Berücksichtigung der örtlich unterschiedlichen Wasserhärte ermöglicht und bei optimaler Inanspruchnahme des Ionenaustauschers ein gutes Reinigungsergebnis bei geringstmöglichem Salzverbrauch erzielen läßt.The object of the invention is to provide a method for cleaning of dishes in a household dishwashing machine the Specify the type mentioned at the outset that a setting of the residual hardness of the cleaning liquid in a simple manner taking into account the locally different water hardness and with optimal use the ion exchanger can achieve a good cleaning result with the lowest possible salt consumption.

Die erfindüngsgemäße Lösung dieser Aufgabe ist dem Kennzeichen des Patentanspruches zu entnehmen.The solution to this problem according to the invention is the identifier of the claim.

Es wurde gefunden, daß der Effekt beim Reinigen und Zwischenspülen dann am größten ist, wenn die Reinigungsflüssigkeit eine Resthärte bis 8° d„ aufweist. Um den Verbrauch von Weichwasser niedrig zu halten ist man bestrebt in möglichst vielen Programmabschnitten Hartwasser oder nur teilweise enthärtetes V/asser zu verwenden, falls dadurch das Reinigungsergebnis nicht negativ beeinflußt wird ο Verlangt ein Spülprogramm nur eine kleine Weichwassermenge so erübrigt sich ein voluminöser Ionenaustauscher und der zur Regenerierung erforderliche Salzverbrauch kann eingeschränkt werden. Durch die Erfindung kann sowohl beim Reinigen als auch beim Zwischenspülen mit nur teilweise enthärtetem Wasser gearbeitet werden und der eine gute Reinigungs- bzw. Spülwirkung ermöglichende Resthärtegrad des Wassers ist auf einfache Weise durch die zeitliche Steuerung des Prischwasseranteils und die niveaugesteuerte Auffüllung mit Weichwasser auf das vorgegebene Füllniveau des Spülbehälters einstellbar,; wobei diese Einstellung den jeweils örtlich verschiedenen Härtegrad des Frischwassers über den Frischwasseranteil berücksichtigt,,It has been found that the effect during cleaning and intermediate rinsing is greatest when the cleaning liquid has a residual hardness of up to 8 ° d ". One is to keep the consumption of soft water low endeavors to use hard water or only partially softened water in as many program sections as possible, if this does not adversely affect the cleaning result ο If a wash program only requires a small amount of soft water, a bulky ion exchanger is not necessary and the salt consumption required for regeneration can be restricted. The invention can be used both during cleaning and during intermediate rinsing work with only partially softened water and which enables a good cleaning or rinsing effect The residual degree of hardness of the water can be easily controlled by timing the proportion of water in the water and the level-controlled filling with soft water can be adjusted to the specified filling level of the washing compartment; whereby this setting is locally different The degree of hardness of the fresh water is taken into account via the fresh water proportion,
