Abstract

Die Nassbehandlung von Wäschestücken erfolgt in gewerblichen Wäschereien mit Wäscheposten aus einer Vielzahl von Wäschestücken. Eine drehend antreibbare Trommel (11) wird mit allen Wäschestücken des Wäschepostens auf einmal beladen. Dabei gelangen die Wäschestücke in einer losen Schüttung in die Trommel (11), so dass die Wäschestücke in der Trommel (11) viel Platz einnehmen. Das beeinträchtigt die Wirtschaftlichkeit der Nassbehandlung.The wet treatment of laundry items is carried out in commercial laundries with laundry batches consisting of a large number of laundry items. A rotating drum (11) is loaded with all the laundry items in the laundry batch at once. The laundry items enter the drum (11) in a loose pile, so that the laundry items take up a lot of space in the drum (11). This impairs the economic efficiency of the wet treatment.

Die Erfindung sieht es vor, die Trommel (11) in mehreren Schritten zu beladen. Der Wäscheposten wird dazu in Teilposten unterteilt, die nach und nach in die Trommel (11) geladen werden. Insbesondere wird zwischen aufeinanderfolgenden Teilposten die Trommel (11) mit einer Drehzahl angetrieben, die der Schleuderdrehzahl entspricht und/oder den Teilposten beim Beladen Flüssigkeit zuführt. Dadurch findet eine Verdichtung der einzelnen Teilposten statt. Infolge dieser Verdichtung wird Platz geschaffen für den nächsten Teilposten. Dadurch kann die Trommel (11) mit größeren Wäscheposten höheren Gewichts beladen werden. Das hat eine wirtschaftlichere Nassbehandlung zur Folge.

Figure imgaf001
The invention provides for loading the drum (11) in several steps. The laundry batch is divided into sub-batches, which are gradually loaded into the drum (11). In particular, between successive sub-batches, the drum (11) is driven at a speed that corresponds to the spin speed and/or liquid is added to the sub-batches during loading. This results in the individual sub-batches being compressed. As a result of this compression, space is created for the next sub-batch. This means that the drum (11) can be loaded with larger, heavier laundry batches. This results in more economical wet treatment.
