Verfahren und Vorrichtung zum Betreiben einer GeschirrspülmaschineMethod and device for operating a dishwasher

Die Erfindung bezieht sich auf ein Verfahren und. eine Vorrichtung zum Betreiben einer Geschirrspülmaschine, in welcher das Geschirr vorgespült, gereinigt, klargespült und getrocknet wird, wobei nach jedem Spülgang die Spülflotte abgelassen und vor jedem Spülgang kaltes, in der Geschirrspülmaschine aufzuheizendes Frischwasser eingelassen wird.The invention relates to a method and. a device for operating a dishwasher in which the dishes are pre-rinsed, cleaned, rinsed clear and dried is drained after each wash cycle, the washing liquor and before each wash cycle cold, in the dishwasher fresh water to be heated is admitted.

Bei einem solchen bekannten Verfahren nach der DT-OS 1 503 762 wurde zum Druckausgleich im Spülbehälter, hervorgerufen durch den Flottenwechsel, vorgeschlagen, daß man nach jedem mit warmer Spülflotte durchgeführten Spülgang, jedoch vor dem Einschalten der die Sprüharme mit Frischwasser speisenden Umwälzpumpe, den Spülbehälterraum durch Zerstäuben von kaltem Wasser einnebelt und dadurch die im Spülbehälter verbliebene warme Luft zum Druckausgleich langsam abkühlt.In such a known method according to DT-OS 1 503 762, pressure equalization in the washing container was brought about by changing the liquor, suggested that after each wash cycle carried out with warm wash liquor, however, before switching on the circulation pump that feeds the spray arms with fresh water, enter the wash compartment by atomizing cold water and thereby using the warm air remaining in the rinsing container to equalize the pressure slowly cools down.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Verbesserung des Reinigungsergebnisses "bei einer Geschirrspülmaschine anzugeben.The invention is based on the object of a method and to specify a device for improving the cleaning result "in a dishwasher.

Dies wird nach dem erfindungsgemäßen Verfahren dadurch erreicht, daß nach jedem mit warmer Spülflotte durchgeführten Spülgang bei laufender Entleerungspumpe jedoch abgeschalteter Umwälzpumpe das Geschirr durch vorgeheiztes und/ oder kaltes Frischwasser abgeduscht wird.This is achieved according to the method according to the invention in that after each one is carried out with warm washing liquor Wash the dishes with the drain pump running but with the circulation pump switched off. or cold fresh water is showered.

Eine Verbesserung des Reinigungsergebnisses wird damit erreicht, da während einer vorgegebenen Zeit, während der gleichzeitig die Entleerungspumpe läuft, die auf dem Geschirr vom Reinigungsvorgang her feinverteilten Schmutzteilchen abgespült und mit der zu entleerenden, verbrauchten Reinigungsflotte durch die Entleerungspumpe aus dem Spülbehälter entfernt werden. Weben der Verbesserung des Reinigungsergebnisses besteht die Möglichkeit, mit geringeren Spülflottenmengen zu arbeiten und/oder von einer Filterung der umzuwälzenden Spülflotte abzusehen. Durch die Einsparung eines Feinfilters für die Spülflotte ergibt sich der weitere Vorteil, daß sich Vorkehrungen zur Reinigung eines Feinfilters erübrigen und der Pumpenleistung der Strömungswiderstand eines Feinfilters nicht entgegenwirkt.An improvement in the cleaning result is achieved by because during a specified time, during which the drain pump is running at the same time, that on the dishes finely distributed dirt particles from the cleaning process rinsed and with the used cleaning liquor to be emptied by the emptying pump from the rinsing container removed. Weaving the improvement of the cleaning result is possible with lower To work wash liquor quantities and / or refrain from filtering the wash liquor to be circulated. By saving A fine filter for the washing liquor has the further advantage that there are provisions for cleaning a fine filter superfluous and the pump performance is not counteracted by the flow resistance of a fine filter.

Zur Durchführung des erfindungsgemäßen Verfahrens ist zum Abduschen des Geschirrs unter dem Spülbehälterdeckel der Geschirrspülmaschine wenigstens ein Wassereinlaß, vorzugsweise mit einer Verteilvorrichtung, z.B. einem SprühkopfTo carry out the method according to the invention is for Showering off the dishes under the washing compartment lid of the dishwasher at least one water inlet, preferably with a distribution device, e.g. a spray head

ο.dgl., vorgesehen. Um ein Abschrecken des mit einer warmen Spülflotte erhitzten Geschirrs zu verhindern, kann der Wassereinlaß für das Abduschen des Geschirrs an einen heizbaren Vorwärmbehälter und an die Frischwasserzuleitung der Geschirrspülmaschine angeschlossen sein. Es ist aber auch möglich, den Wassereinlaß für das Abduschen nur mit kaltem Frischwasser zu beschicken.ο the like., Provided. To quench the with a warm To prevent dishwashing from heated dishes, the water inlet for showering the dishes can be switched to a heatable one Preheating container and be connected to the fresh water supply line of the dishwasher. It is also possible to fill the water inlet for showering only with cold fresh water.
