Abstract

Bei der Nassbehandlung von Wäschestücken wird ein Teil der Behandlungsflüssigkeit zur Behandlung eines nachfolgenden Postens an Wäschestücken wiederverwendet. Der Anteil der wiederverwendbaren Behandlungsflüssigkeit ist jedoch bei bekannten Verfahren zur Nassbehandlung von Wäschestücken begrenzt, so dass noch verhältnismäßig viel Frischwasser erforderlich ist.In the wet treatment of laundry, a portion of the treatment liquid is reused to treat a subsequent batch of laundry. However, the proportion of reusable treatment liquid is limited in known methods for wet treatment of laundry, so that relatively much fresh water is required.

Die Erfindung sieht es vor, in einer Entwässerungseinrichtung die Klarwaschflüssigkeit aus der Wascheinrichtung von den Wäschestücken zu trennen, und zwar zusammen mit einem Großteil der in den Wäschestücken gebundenen Klarwaschflüssigkeit. Danach findet in der Entwässerungseinrichtung ein Spülen der Wäschestücke statt. Im Anschluss hieran wird die Spülflüssigkeit von den Wäschestücken abgeführt. Die Klarwaschflüssigkeit und die Spülflüssigkeit werden in getrennten Speichertanks (20, 21) zwischengelagert und gezielt dem nachfolgenden Waschprozess wieder zugeführt. Insbesondere der Vorwaschzone (16) wird ein Gemisch aus mindestens einem Teil der Klarwaschflüssigkeit und der Spülflüssigkeit zum Vorwaschen des nächstens Postens an Wäschestücken zugeführt.

Figure imgaf001
The invention provides for separating the clear wash liquid from the washing device from the laundry items in a dewatering device, together with a large part of the final wash liquid bound in the laundry items. Thereafter, a rinsing of the laundry takes place in the drainage device. Following this, the rinsing liquid is removed from the laundry. The clear wash liquid and the rinsing liquid are stored in separate storage tanks (20, 21) and selectively returned to the subsequent washing process. In particular, the prewash zone (16) is supplied with a mixture of at least part of the final wash liquid and the rinse liquid for prewashing the next batch of laundry items.
