Abstract
Description
Verfahren zum wassersparenden Abkühlen einer WaschlaugeProcess for the water-saving cooling of a washing liquor
Die Erfindung geht aus von einem Verfahren zum Abkunlen einer Waschlauge durch Kaltwasserzufuhr am Anfang eines Spülprogramms in einer automatisch gesteuerten Trommelwaschmaschine mit einer Niveausteuerung bei einem oberen und einem unteren Niveau.The invention is based on a method for cooling down a washing liquor by supplying cold water at the beginning of a washing program in an automatically controlled one Drum washing machine with level control at an upper and a lower one Level.
Ein derartiges Vorfahren ist aus der DE-AS ii 52 679 bekannt, in der eiy Wechselspülprogramm mit hohem Niveauunterschied beschrieben ist. Darin wird im Anschluß an den Waschprozess der heißen Lauge zunächst kaltes Frischwasser zugeführt. Hierbei steigt der Laugenstahd bis weit Ueber das bei normalem Waschen übliche Niveau. Beim Erreichen eines bestimmten Laugenhöchststandes erfolgt dann automatisch die Abschaltung der Wasserzufuhr und das Abführen der Schmutzlauge bis auf ein sehr niedriges Niveau.Such an ancestor is known from DE-AS ii 52 679 in which An alternating wash program with a high level difference is described. In it will After the washing process, cold fresh water is first added to the hot lye. Here, the lye rises far above the level that is usual for normal washing. When a certain maximum lye is reached, the Shutdown of the water supply and the removal of the dirty liquor except for a very low level.
Die sich weiterbewegende Trommel hat dann nur kurzfristig Gelegenheit, die Lauge zu durchmischen, und in den vielen Falten bleibt noch ein erheblicher Teil von unverdünnter, heißer Lauge eingeschlossen.The moving drum then only has a short-term opportunity to to mix the lye, and in the many Wrinkles still remain a significant part of undiluted, hot lye included.
Der Erfindung liegt die Aufgabe zugrunde die Laugenabkühlung und -verdUnnung schon beim ernsten Zuführen von Kaltwasser so zu optimieren, daß infolge von höchstens drei wechselweise ablaufenden Zu- un; Abf lußvorgängen eine erhebliche Wassermenge gespart Werden kann.The object of the invention is to cool and dilute the lye to optimize even with the serious supply of cold water so that as a result of at most three alternately running inlets; Drainage processes a considerable amount of water Can be saved.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß beide Niveaus wesentlich über dem beim Waschprozess üblichen Niveau liegen und beim Erreichen des oberen Niveaus der durch zugeflossenes Kaltwasser verdünnten Waschlauge die Wäsche trommel für 5 bis 30 Sekunden bewegt, danach die Waschlauge bis zum unteren Niveau abgeführt und dann bis zum Erreichen des oberen Niveaus wieder Kaltwasser zugeführt wird.According to the invention this object is achieved in that both levels are significantly above the level customary in the washing process and when it is reached of the upper level of the washing liquor diluted by the inflow of cold water The washing drum is moved for 5 to 30 seconds, then the detergent solution down to the lower level Level discharged and then cold water again until the upper level is reached is fed.
Hierdurch kann in vorteilhafter Weise gegenüber dem Stand der Technik schon während des ersten Spülganges ein intensiver Temperatur- und Konzentrationsausgleich in der Waschlauge stattfinden. Beim nachfolgenden vollständigen AbfUhren der durchmischten Lauge wird daher ein höher Prozentsatz der in der Waschlauge enthaltenen Verunreinigungen abgeführt.This can be advantageous compared to the prior art An intensive temperature and concentration equalization even during the first rinse take place in the detergent solution. During the subsequent complete removal of the mixed Lye will therefore have a higher percentage of the impurities contained in the wash liquor discharged.
In einer vorteilhaften Ausbildung des erfindungsgemXßeS Verfahrens werden die angegebenen Verfahrens schritte ein bis zweimal wiederholt.In an advantageous embodiment of the method according to the invention the specified process steps are repeated once or twice.
Es hat sich nämlich gezeigt, daß diese geringe Anzahl von Pendel-Spülvorgängen im ersten Spülgang bereits ausreicht, um den abgelösten Schmutz und den größten Teil der Waschmittelreste aus der Wäsche auszuspülen. Im Vergleich zum Stand der Technik, bei dem bis zu fünf derartige Spül gänge mit erheblich größeren Niveauunterschieden notwendig sind, ergibt sich bei Anwendung des erfindungsgemäßen Verfahrens eine beträchtliche Wassereinsparung.It has been shown that this small number of pendulum flushing processes in the first rinse is already sufficient to remove the loosened dirt and the largest Part of the detergent residue Rinse out of the laundry. In comparison the prior art, in which up to five such flush courses with significantly larger Differences in level are necessary, results when using the invention Process a considerable water saving.
