Die Aufgabe der Erfindung besteht darin, ein wasserführendes Haushaltsgerät, insbesondere Geschirrspül- oder Waschmaschine, sowie ein Spülverfahren für ein solches wasserführendes Haushaltsgerät bereitzustellen, bei dem eine Rückanschmutzung des Spülguts zuverlässig verhindert wird.The The object of the invention is a water-leading Domestic appliance, in particular dishwashing or Washing machine, as well as a rinse for a to provide such water-conducting household appliance, in which a Rückanschmutzung the dishes reliably is prevented.
Die Aufgabe der Erfindung ist durch die Merkmale des Patentanspruches 1 oder des Patentanspruches 18 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen offenbart.The The object of the invention is characterized by the features of claim 1 or of claim 18 solved. Advantageous developments of Invention are disclosed in the subclaims.
Gemäß dem kennzeichnenden Teil des Patentanspruches 1 weist das wasserführenden Haushaltsgerät ein Zusatzfilter auf, durch das Spülflotte wenigstens zeitweise in einem Teilprogrammschritt leitbar ist. So kann bei Bedarf, bspw. vor einem Klarspülgang in einer Geschirrspülmaschine, Spülflotte mittels des Zusatzfilters gereinigt werden, um eine Rückanschmutzung von zu reinigendem Gut, insbesondere Spülgut, zu verhindern. Zugleich wird durch die nur bedarfweise Reinigung von Spülflotte durch das Zusatzfilter erreicht, dass sich das Zusatzfilter nur langsam durch Filterkuchenbildung zusetzt.According to the characterizing part of claim 1, the water-bearing Household appliance on an additional filter, by the wash liquor at least temporarily in a subprogram step is conductive. So can at Need, for example, before a rinse cycle in a dishwasher, Rinsing liquor can be cleaned by means of the additional filter, to a Rückanschmutzung of to be cleaned Good, in particular Wash items to prevent. At the same time, only by necessity Cleaning of rinsing liquor by the additional filter achieved, that the additional filter only slowly through filter cake formation added.
Dabei ist vorzugsweise vorgesehen, dass das Zusatzfilter eine kleinere Maschenweite als die als Vorfilter dienenden Filter aufweist und damit eine Filtration kleinster Partikel erlaubt.there is preferably provided that the additional filter a smaller Has mesh size as the filter serving as a pre-filter and thus allowing filtration of very small particles.
Es ist ferner vorzugsweise vorgesehen, dass der Hydraulikkreislauf einen Bypass aufweist, in dem das Zusatzfilter angeordnet ist. Hierzu ist vorzugsweise der Bypass durch eine Flüssigkeitshauptleitung und eine Flüssigkeitsnebenleitung gebildet, wobei das Zusatzfilter in der Flüssigkeitsnebenleitung angeordnet ist.It is further preferably provided that the hydraulic circuit has a bypass, in which the additional filter is arranged. For this is preferably the bypass through a liquid main and a secondary fluid line, wherein the auxiliary filter is arranged in the liquid secondary line.
Des Weiteren ist vorzugsweise dem Haushaltsgerät ein Umlenkelement zugeordnet, bei dessen Betätigung das Zusatzfilter, etwa der Filter mit der geringsten Maschenweite vom Hydraulikkreislauf entkoppelbar oder dem Hydraulikkreislauf zuschaltbar ist. Somit ist erreicht, dass der Filter mit der geringsten Maschenweite nicht über den ganzen Spülzyklus im Hydraulikkreislauf eingebunden ist, sondern lediglich bei vorgegebenen Abschnitten des Spülzyklus zuschaltbar ist. Es kann jedoch auch vorgesehen sein, dass z. B. mittels einer Strömungsumkehr, bspw. hervorgerufen durch eine Drehrichtungsumkehr einer Pumpe, Spülflotte durch das Zusatzfilter im Bedarfsfall geleitet wird.Of Furthermore, the household appliance is preferably a deflecting element associated with the actuation of the additional filter, such as the filter with the smallest mesh size of the hydraulic circuit can be decoupled or the hydraulic circuit is switchable. Thus it is achieved that the filter with the smallest mesh size is not over involved in the entire cycle in the hydraulic circuit is, but only at predetermined portions of the rinse cycle is switchable. However, it may also be provided that z. B. by means of a flow reversal, for example, caused by a reversal of the direction of rotation of a pump, wash liquor through the additional filter is routed if necessary.
Der in der Filterkombination vorgesehene Filter mit der geringsten Maschenweite ist besonders anfällig bei einer Grobschmutz-Filtration. Mittels der Erfindung kann daher insbesondere der Filter mit der geringsten Maschenweite bei grob verschmutzter Spülflotte während des Reinigungsschrittes vom Hydraulikkreislauf entkoppelt sein und erst bei einem darauffolgenden Zwischenspül- oder Klarspülschritt zugeschaltet werden. Während des Reinigungsschrittes ist die von den als Vorfilter dienenden Filtern erfolgende Grobfiltration der Spülflotte ausreichend. Im darauffolgenden Zwischenspül- bzw. Klarspülschritt wird der Filter mit der geringsten Maschenweite zugeschaltet, wodurch eine Microfiltration erfolgt, mittels der eine Rückanschmutzung des Spülgutes verhindert wird.The filter with the smallest mesh size provided in the filter combination is particularly susceptible to coarse dirt filtration. By means of the invention, therefore, in particular the filter with the smallest mesh size can be decoupled from the hydraulic circuit during the cleaning step during the cleaning step and only at a subsequent Intermediate rinse or rinse step are switched on. During the purification step, the coarse filtration of the rinsing liquor carried out by the filters serving as pre-filters is sufficient. In the subsequent intermediate rinsing or rinsing step, the filter is switched on with the smallest mesh size, whereby a microfiltration takes place by means of a Rückanschmutzung the dishes is prevented.
Für eine einfache und zuverlässige Zuschaltung bzw. Entkopplung des Zusatzfilters kann eine der Flüssigkeitsleitungen mit einer Flüssigkeitshauptleitung sowie einer parallel dazu geschalteten Flüssigkeitsnebenleitung ausgebildet sein. In der Flüssigkeitsnebenleitung kann der zuschaltbare bzw. entkoppelbare Zusatzfilter angeordnet sein. Mittels des Umlenkelementes kann dann die Spülflottesströmung durch die Hauptleitung und/oder durch die Nebenleitung geführt werden. Das Umlenkelement kann als Wasserweiche an der Verzweigung zwischen der Hauptleitung und der Nebenleitung geschaltet sein. In Abweichung hierzu kann das Umlenkelement auch als Drehschieber oder Umschaltventil ausgeführt sein.For a simple and reliable connection or decoupling the additional filter can be one of the liquid lines with a liquid main and one parallel to it switched liquid secondary line may be formed. In the secondary fluid line, the switchable or be arranged decoupled additional filter. By means of the deflecting element then can the rinsing flow through the main line and / or be guided by the secondary line. The deflecting element can be used as a water diverter at the junction between the main line and the secondary line be switched. In deviation to this can the deflection also be designed as a rotary valve or changeover valve.
Der zuschaltbare Zusatzfilter kann bevorzugt an der Druckseite der Umwälzpumpe angeordnet sein, an der die Pumpe weniger anfällig für Druckschwankungen in der Spülflottesströmung ist, die durch das Umschaltventil hervorgerufen werden können. Durch die druckseitige Anordnung des Zusatzfilters, d. h. durch seine Anordnung außerhalb des Pumpentopfes, kann dieser entsprechend kleiner dimensioniert werden. Dadurch erhöht sich entsprechend der Bauraum unterhalb des Spülbehälter-Bodens.Of the switchable additional filter can preferably on the pressure side of the circulation pump be arranged at which the pump less prone to Pressure fluctuations in the purge flow is which can be caused by the switching valve. By the pressure-side arrangement of the additional filter, d. H. by his arrangement outside the sump, this can be sized correspondingly smaller. This increases according to the space below the sink bottom.
Außerdem wird mit einem kleineren Pumpentopf auch die darin befindliche Totwassermenge und somit auch die erforderliche Heizleistung zur Erwärmung der Spülflotte reduziert. In dem kleineren Pumpentopf können somit lediglich die Filter größerer Maschenweite, etwa ein als Flächensieb ausgeführter Grobfilter sowie ein darunter angeordneter Feinsiebzylinder, saugseitig der Umwälzpumpe angeordnet sein.Furthermore is with a smaller sump and the dead water contained therein and thus also the required heating power for heating the rinsing liquor reduced. In the smaller sump can thus only the filters of larger mesh size, for example, a rough filter designed as a flat screen and a arranged below Feinsiebzylinder, suction side of the Circulating pump be arranged.
Wie oben bereits erwähnt, ist bevorzugt der Filter mit der geringsten Maschenweite an der Druckseite der Umwälzpumpe als Zusatzfilter angeordnet. Der somit außerhalb des Pumpentopfes vorgesehene Zusatzfilter ist daher zur Reinigung schwer zugänglich. Der Zusatzfilter kann daher bevorzugt selbstreinigend gestaltet sein. Ein derart selbstreinigender Filter kann ein Filtermittel aufweisen, dessen Filteroberfläche von der Spülflotte in einer Querströmung überströmbar ist. Beim Überströmen wird ein auf der Filteroberfläche befindlicher Filterkuchen abgetragen, der in eine Ableitung aus dem Gehäuse des Filters führbar ist. Die Ableitung des Filtergehäuses kann strömungstechnisch mit dem am Spülbehälter-Boden vorgesehenen Pumpentopf verbunden sein, über den der Filterkuchen in das Abwassersystem abgeführt wird. Es kann jedoch auch bspw. eine drehbarer Zusatzfilter vorgesehen sein, der in Rotation versetzt wird und dann entweder Fliehkräfte oder Schaber bzw. Rakel einen Filterkuchen entfernen.As already mentioned above, is preferably the filter with the smallest mesh size on the pressure side of the circulation pump arranged as an additional filter. The thus outside of the sump provided additional filter is therefore difficult to access for cleaning. The additional filter can therefore be designed preferably self-cleaning be. Such a self-cleaning filter can be a filter medium have, the filter surface of the wash liquor can be overflowed in a transverse flow. When overflowing, a on the filter surface located filter cake removed, which in a derivative of the housing of the filter is feasible. The derivative the filter housing can flow with the pump pot provided at the bottom of the washing tub Be connected over the filter cake in the sewage system is dissipated. However, it can also, for example, a rotatable Additional filter be provided, which is set in rotation and then either centrifugal forces or scraper or squeegee one Remove filter cake.
