Abstract

When both colored and white wash are to be laundered together, one has the problem that pigment particles are transported from the colored pieces to the white pieces and the white pieces are discolored. This problem will be eliminated in a novel counterflow cycling washing machine by providing additional components besides the control components for the counterflow which produce a reversal of the usual counterflow to concurrent flow when a colored piece of wash is in the machine or the washing zone. For concurrent flow operation switchover of the valves permits the head of the washing liquid in the upstream compartment of the washing zone to cause the flow through this zone to the downstream compartment where the concurrent flow liquid is discharged.

Description

Die Erfindung betrifft eine Gegenstrom-Taktwaschmaschine mit mehrere Waschkammern aufweisenden Waschzonen.The invention relates to a countercurrent cycle washing machine with washing zones having a plurality of washing chambers.

Zum Waschen von großen Wäschemengen werden kontinuierlich arbeitende Waschstraßen eingesetzt. Allgemein durchgesetzt haben sich dabei nach dem Strömungsverfahren arbeitende Waschstraßen und insbesondere wegen des sparsamen Wasser- und Energieverbrauchs im Gegenstrom arbeitende Taktwaschanlagen. Die um ihre Längsachse drehend antreibbare Waschtrommel ist dabei in eine Anzahl Waschkammern unterteilt, und mehrere.Waschkammern sind zu Waschzonen zusammengefaßt, z.B. in eine Einweichzone, Klarwaschzone und eine Spülzone. Der in die Beschickungskammer eingegebene Wäscheposten durchläuft taktweise die einzelnen Waschkammern und Waschzonen. Am Ende der Waschtrommel wird Frischwasser zugeführt, welches mindestens teilweise die Waschtrommel im Gegenstrom zur Wäsche durchströmt. Dieses Verfahren ist problemlos, wenn in einer solchen Anlage nur weiße Wäsche gewaschen wird.Continuous washing lines are used to wash large quantities of laundry. In general, washing lines that work according to the flow method and, in particular, because of the economical water and energy consumption in countercurrent washing systems have become established. The washing drum, which can be driven to rotate about its longitudinal axis, is divided into a number of washing chambers, and several washing chambers are combined into washing zones, e.g. in a soaking zone, rinsing zone and a rinsing zone. The laundry item entered in the loading chamber cycles through the individual washing chambers and washing zones. At the end of the washing drum, fresh water is supplied, which at least partially flows through the washing drum in countercurrent to the laundry. This procedure is problem-free if only white laundry is washed in such a system.

Der Anteil der farbigen Wäsche (Buntwäsche)., wie z.B. grüne oder blaue Operationswäsche, farbige Bettwäsche oder Tischwäsche ist in den Wäschereien jedoch schon sehr groß, und steigt noch weiter.The proportion of colored laundry (colored laundry), e.g. However, green or blue surgical linen, colored bed linen or table linen is already very large in the laundries and is still increasing.

Wenn jedoch in einer Taktwaschanlage Buntwäsche und anschließend Weißwäsche gewaschen wird, dann fließen durch den Gegenstrom Farbpartikel von der farbigen Wäsche zur weißen Wäsche und verfärben diese.However, if colored laundry and then white laundry are washed in a cycle washing machine, then color particles flow from the colored laundry to the white laundry and discolor them due to the countercurrent.

Da das Verfärben von Weißwäsche nicht auftreten darf, wird die Buntwäsche entweder in separaten Einzelmaschinen oder in einer "Badwechsel-Waschstraße" gewaschen, welche nicht im Gegenstrom arbeitet. Dies bedeutet höhere Investitionskosten, da die Badwechselwaschstrasse erheblich teurer ist als eine Gegenstrom-Waschstraße, und es bedeutet höhere Waschkosten, da die Verbräuche dieser Anlagen erheblich höher liegen als bei einer Gegenstrom-Waschstraße.Since the discoloration of white laundry is not allowed to occur, the colored laundry is either washed in separate individual machines or in a "bath change wash line", which does not work in countercurrent. This means higher investment costs, since the bath-changing car wash is considerably more expensive than a counter-current car wash, and it means higher washing costs, since the consumption of these systems is considerably higher than that of a counter-current car wash.

Wenn man wegen dieser Nachteile die Buntwäsche trotzdem in einer Gegenstrom-Waschstraße mitwaschen will, dann muß ein großer Teil der nachfolgenden Waschkammern leer gelassen werden, um das Verfärben der nachfolgenden Weißwäsche zu verhindern.If, because of these disadvantages, you still want to wash the colored laundry in a countercurrent car wash, then a large part of the subsequent wash chambers must be left empty in order to prevent the subsequent white laundry from becoming discolored.

Bei stark färbender Buntwäsche müssen in der Regel 60 - 70 % der Kammern einer Waschstraße leergefahren werden.In the case of strongly staining colored laundry, 60 - 70% of the compartments in a car wash usually have to be run dry.

Dadurch wird die Leistung einer Waschstraße erheblich reduziert, während andererseits die Verbräche nicht reduziert werden, denn Wasser, Dampf und Waschmittel müssen weiter zugeführt werden, auch wenn keine Wäsche in den Kammern ist.This significantly reduces the performance of a car wash, while on the other hand it does not reduce consumption, because water, steam and detergent must continue to be fed even if there is no laundry in the chambers.

Um diese Leerkammern zu vermeiden, wird in der DE-OS 29 49 228 vorgeschlagen, über eine Vielzahl von Ventilen und Umgehungsleitungen, den Gegenstrom jeweils um die Waschkammer herumzulenken, in welcher sich ein Posten Buntwäsche befindet. Es wird also der Gegenstrom im Prinzip aufrecht erhalten und nur für die mit Buntwäsche gefüllte Waschkammer laufend eleminiert. Es liegt auf der Hand, daß hierzu eine teure und umständliche Steuerungsvorrichtung notwendig ist.In order to avoid these empty chambers, it is proposed in DE-OS 29 49 228 to use a plurality of valves and bypass lines to divert the countercurrent around the washing chamber in which there is a batch of colored laundry. In principle, the countercurrent is maintained and only continuously eliminated for the wash chamber filled with colored laundry. It is obvious that an expensive and cumbersome control device is necessary for this.

Der Erfindung liegt die Aufgabe zugrunde, in einer Gegenstrom-Taktwaschmaschine mit einfachem Mitteln Buntwäsche und Weißwäsche direkt hintereinander zu waschen, d.h. ohne daß Leerkammern notwendig sind.The object of the invention is to wash colored laundry and white laundry in a countercurrent cycle washing machine with simple means, i.e. without the need for empty spaces.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, ,daß man die Maschine oder einzelne Waschzonen von Gegenstrombetrieb auf Mitstrombetrieb (Badstrom-Umkehr) umschaltet, solange sich ein Posten Bundwäsche in der Maschine befindet. Die Badstrom-Umkehr wird mit den im Patentanspruch angegebenen Mitteln und Maßnahmen erreicht.This object is achieved in that the machine or individual washing zones are switched from counter-current operation to co-current operation (bath flow reversal) as long as there is a lot of bundle washing in the machine. The bath flow reversal is achieved with the means and measures specified in the claim.

Man hat auf diese Weise die Vorteile einer Gegenstrom-Taktwaschmaschine mit den Vorteilen einer nach dem Mehrlaugenverfahren arbeitenden Waschmaschine so kombiniert, daß ohne große Mehraufwendungen die Maschine nach dem einen oder dem ander Verfahren betrieben werden kann.In this way, the advantages of a countercurrent cycle washing machine have been combined with the advantages of a washing machine which operates according to the multi-lye process in such a way that the machine can be operated in one or the other process without great additional expenditure.

Die Erfindung wird nachstehend anhand der Zeichnung erläutert und dargestellt.The invention is explained and illustrated below with reference to the drawing.

Es zeigen schematisch:

  • Fig. 1: die bei Gegenstrombetrieb in Funktions gesetzten Steuerorgane und Leitungen.
  • Fig. 2: die bei Mitstrombetrieb tätigen Organe.
They show schematically:
  • Fig. 1: the control elements and lines set in countercurrent operation.
  • Fig. 2: the organs operating in co-current operation.

Die in einzelne Kammer unterteilte Waschtrommel 1 mit den Waschzonen "Einweichen" 2, "Klarwaschen" 3 und "Spülen" 4 wird um ihre Längsachse drehend angetrieben, wobei die bei 5 eingegebenen Wäscheposten die Maschine in bekannter Weise durchlaufen und am Entleerungsende 6 in eine nachgeschaltete Presse übernommen werden. Üblicherweise wird die Waschlauge im Gegenstrom zum Weg der Wäscheposten geführt wie in Fig. 1 für den Bereich der Klarwaschzone 3 dargestellt ist. Die Waschlauge wird am Ende der Klarwaschzone bei 7 zugeführt und über den Überlauf 8 am Anfang der Klarwaschzone abgeführt. Um im Bedarfsfalle die Waschlauge auch im Mitstrom führen zu können ist zu Beginn der Klarwaschzone zusätzlich ein Waschlaugenzulauf 9 und am Ende der Klarwaschzone ein weiterer Überlauf 10 vorgesehen, so daß die Waschlauge gemäß Pfeil auch im Mitstrom geführt werden kann. Dabei sind die Ventile 11 und 12 geschlossen und die Ventile 13 und 14 geöffnet. Bei Gegenstrombetrieb ist die Schaltung umgekehrt wie aus der Zeichnung Fig. 1 zu erkennen ist. Die den Gegenstrom erzeugende Pumpe ist bei Mitstrombetrieb ausgeschaltet.The washing drum 1, which is divided into individual chambers, with the washing zones “soaking” 2, “rinsing” 3 and “rinsing” 4 is driven in rotation about its longitudinal axis, the items of laundry entered at 5 passing through the machine in a known manner and at the emptying end 6 into a downstream one Press are taken over. The wash liquor is usually conducted in countercurrent to the route of the laundry items, as shown in FIG. 1 for the area of the clear wash zone 3. The wash liquor is fed in at the end of the rinsing zone at 7 and discharged via the overflow 8 at the beginning of the rinsing zone. In order to be able to carry the wash liquor in the co-flow if required, a wash liquor inlet 9 is additionally provided at the beginning of the clear wash zone and a further overflow 10 is provided at the end of the clear wash zone, so that the wash liquor can also be carried out in the co-stream according to the arrow. The valves 11 and 12 are closed and the valves 13 and 14 are open. In countercurrent operation, the circuit is reversed as can be seen from the drawing in FIG. 1. The counter-current pump is switched off in the co-current mode.

Das für den Bereich der Klarwaschzone als Ausführungsbeispiel dargestelle Verfahren ist auch für die anderen Waschzonen oder für die ganze Maschine.anwendbar.The method illustrated as an exemplary embodiment for the area of the clear wash zone can also be used for the other wash zones or for the entire machine.
