Description

ErfindungsgebietTHE iNVENTION field

Die Erfindung bezieht sich auf eine Methode und eine Vorrichtung zur Behandlung von Textilien mit flüssigen Mitteln wie z.B. Waschmittellösung, flüssigen Farben, synthetischen Lösungsmitteln usw. Diese Behandlungsmethode und eine bevorzugte Ausführungsform der Vorrichtung zu Durchführung des Verfahrens wird im Folgenden am Beispiel eines Waschvorgangs beschrieben.The invention relates to a method and a device for treating textiles with liquid agents, such as e.g. Detergent solution, liquid paints, synthetic solvents, etc. This treatment method and a preferred embodiment of the apparatus for carrying out the method will be described below using the example of a washing process.

Hintergrund der ErfindungBackground of the invention

Die am meisten verbreitete Methode, die Schmutzpartikel aus der Wäsche zu entfernen, ist die Nassbehandlung mit einer Waschmittellösung. Die Lauge wird in Bezug zur Wäsche auf unterschiedliche Art und Weise in Bewegung gesetzt. Sie hat die Aufgabe, die Schmutzpartikel vom Gewebe zu lösen und wegzutragen.
In der Vergangenheit hat man bei der Handwasch-Technik diesen Effekt durch das Schlagen auf die Wäsche oder durch das Schlagen der Wäsche gegen unbewegliche Gegenstände oder durch wiederholtes Zusammenpressen und Lockern der getränkten Stücke erzielt. Beim Einsatz des Waschbretts hat man diese Wirkung durch das Reiben der getränkten Wäschestücke erreicht.
Durch den technischen Fortschritt wurden Geräte mit einer stationären Waschtrommel konstruiert die die Lauge mechanisch in Bewegung gesetzt haben. Die Waschlauge wird hier in Gang gesetzt, die Wäsche wird mitgenommen, befindet sich permanent in Bewegung, dabei wird sie zusammengepresst und wieder gelockert, wodurch die Schmutzpartikel mitgerissen und abgetragen werden.
Eine weitere Methode, die Waschmittellösung in Bezug zur Wäsche in Bewegung zu bringen, ist aus DE 2138086 bekannt. Hier wird die Lauge mit einer Pumpe umgewälzt und fließt durch die Wirkung der Gravitationskraft durch die Wäsche.
Eine andere Technik nutzt die Zentrifugalkraft wie z.B. die aus dem Stand der Technik bekannte Vorrichtung nach DE 42 368 73 A1 oder DE 102 25 693 A1 . Die Wäsche wird in einer rotierenden Trommel mit Lauge besprüht und durch den Effekt der Zentrifugalkraft fließt die Lauge durch die Wäsche.The most common way to remove the debris from the laundry is to wet it with a detergent solution. The liquor is set in motion in relation to the laundry in different ways. It has the task of removing the dirt particles from the tissue and carry away.
In the past, in the hand washing technique, this effect has been achieved by hitting the laundry or hitting the laundry against immovable items or by repeatedly squeezing and loosening the soaked pieces. When using the washboard has achieved this effect by rubbing the soaked laundry.
As a result of the technical progress, devices were constructed with a stationary washing drum which mechanically set the liquor in motion. The wash liquor is set in motion, the laundry is taken along, is constantly in motion, it is compressed and loosened again, whereby the dirt particles are entrained and removed.
Another way to get the detergent solution moving in relation to the laundry is over DE 2138086 known. Here, the liquor is circulated by a pump and flows through the action of gravitational force through the laundry.
Another technique uses centrifugal force, such as the device known in the art DE 42 368 73 A1 or DE 102 25 693 A1 , The laundry is sprayed with lye in a rotating drum and by the effect of the centrifugal force, the liquor flows through the laundry.

Es gibt auch Techniken bei denen die Bewegung der Waschmittellösung in Bezug zu Wäsche dadurch erzeugt wird, dass die Lauge in Oszillation gebracht wird. Dies ist z.B. aus WO 9521954 A1 bekannt.
Die Methoden mit Nutzung des Zentrifugaleffektes, des Umlaufs oder der Oszillation der Lauge sind bei der Umsetzung problematisch, weil der Laugenfluss im Inneren der Wäschemasse häufig nicht mit der nötigen Intensität für einen wirkungsvollen Waschvorgang gewährleistet ist. Die Waschlauge nimmt immer den Weg des kleinsten Widerstandes, der oft nicht durch das Wäschegut, sondern möglicherweise zum größten Teil durch die Zwischenräume der einzelnen Wäschestücke führt, je nachdem, wie die Konstellation innerhalb der Wäschemasse beschaffen ist.
Eine weitere Behandlungsweise besteht darin, das Waschgut mechanisch mit einem Stempel zu bewegen und zusammenzudrücken wie z.B. bei dem, aus dem Stand der Technik bekannten DE 198 09 949 A1 mit einem formstabilen Stempel, oder WO 2006/010970 A1 mit einer flexiblen Glocke. Durch die Bewegung des Stempels wird auch die Lauge in Bezug zu Wäsche in Gang gesetzt, die Schmutzpartikel aus der Wäsche werden gelöst und entfernt.There are also techniques in which the movement of the detergent solution relative to laundry is produced by causing the liquor to oscillate. This is eg off WO 9521954 A1 known.
The methods using the centrifugal effect, the circulation or the oscillation of the liquor are problematic in the implementation, because the liquor flow is often not guaranteed in the interior of the laundry with the necessary intensity for an effective washing process. The wash liquor always takes the path of least resistance, which often does not pass through the laundry, but possibly for the most part through the interstices of the individual laundry, depending on how the constellation is within the laundry.
Another way of treatment is to move the laundry mechanically with a punch and compress it as in the known from the prior art DE 198 09 949 A1 with a dimensionally stable stamp, or WO 2006/010970 A1 with a flexible bell. By the movement of the stamp, the lye is set in relation to laundry in motion, the dirt particles from the laundry are dissolved and removed.

Die Entwicklung von Waschmaschinen mit einer rotierenden Trommel hat in der Waschtechnik einen weiteren Fortschritt gebracht. Die Wäschestücke werden in der Trommel umgewälzt. Sie werden durch die Bewegung mit der Waschlauge getränkt und umgeworfen, unter dem Gewicht der Wäschemasse zusammengedrückt, die Lauge wird dabei aus der Wäsche ausgepresst und die Schmutzpartikel werden mitgenommen. Die Waschtechnik mit einer rotierenden Trommel ist am weitesten verbreitet, weil hier gute Reinigungseffekte erzielt werden.
Diese Methode ist jedoch für die Wäschestücke extrem schädlich. Während des Waschvorgangs reiben sie ständig aneinander, verknoten und verwickeln sich, werden großen Zerrungen ausgesetzt. Dies hat zu Folge, dass der Verschleiß der Wäsche auffallend hoch ist. Nicht selten werden die Wäschestücke schon nach wenigen Waschvorgängen deformiert, abgewetzt, die Farbe an den der Reibung besonders stark ausgesetzten Stellen wird abgetragen. Die Teile müssen durch vorzeitigen Verschleiß oder wegen nachgelassenem Tragekomfort und aus ästhetischen Gründen durch neue ersetzt werden. Dieses Verfahren ist zudem bekanntermaßen energieintensiv und nicht immer umweltschonend.The development of washing machines with a rotating drum has brought further progress in the washing technology. The laundry items are circulated in the drum. They are soaked by the movement with the wash liquor and thrown over, compressed under the weight of the laundry mass, the liquor is thereby squeezed out of the laundry and the dirt particles are taken. The washing technique with a rotating drum is the most widespread, because good cleaning effects are achieved here.
However, this method is extremely harmful to the laundry. During the washing process, they are constantly rubbing against each other, knotting and entangling, being subjected to great strains. This has the consequence that the wear of the laundry is strikingly high. Not infrequently, the laundry items are already deformed after a few washes, scuffed, the color on the friction of the particularly exposed areas is removed. The parts must be replaced by premature wear or reduced wear comfort and for aesthetic reasons by new ones. This method is also known to be energy intensive and not always environmentally friendly.

Zusammenfassung der ErfindungSummary of the invention

Zweck der Erfindung ist es, eine Waschtechnik und eine Vorrichtung für den Waschvorgang zu schaffen, die eine effektive Reinigung garantiert, vorzeitigen Verschleiß der Wäschestücke eliminiert und durch effiziente Nutzung von Energie, Wasser sowie der Wasch- und Spülmittel umweltgerecht ist.The purpose of the invention is to provide a washing technique and apparatus for the washing process which ensures effective cleaning, eliminates premature wear on the laundry and is environmentally sound through the efficient use of energy, water and detergents and rinse aids.

Die vorliegende Erfindung erfüllt die Bedingungen dadurch, dass in einem hochdruckfesten Wäschebehälter ein hochvoluminöser Durchfluss der Lauge mit der Hochdrucktechnik erzeugt wird. Die hochintensive Laugenbewegung durch die Fasern der zu waschenden Wäschestücke hindurch wird hier mit hydraulisch erzeugbaren Leistungsparametern ausgeführt.The present invention fulfills the conditions in that in a high-pressure resistant laundry container, a high-volume flow of the liquor is produced by the high-pressure technology. The high-intensity liquor movement through the fibers of the laundry to be washed is carried out here with hydraulically producible performance parameters.

Gemäß der vorliegenden Erfindung wird ein hochintensiver Laugenfluss durch die Wäschemasse hindurch durch Verwendung von Hochdrucktechnik in Verbindung mit einem hochvoluminösen Durchfluss der Waschmittellösung erreicht.
Durch den Flüssigkeitszufluss in den Wäschebehälter bewegt sich die Wäschemasse in Stromrichtung und wird berührungslos, gegen eine flüssigkeitsdurchlässige Stützwand gedrückt. Das Volumen der unter dem Druck stehenden Wäsche reduziert sich stark. Die Lauge wird durch den Auslauf in den Laugenbehälter ausgeschieden und wiederum durch die Hochdruckpumpe zurück in den Umlauf befördert. Die Druckhöhe der Lauge wird den wäschespezifischen Anforderungen angepasst.According to the present invention, a high intensity lye flow through the laundry mass is achieved by using high pressure technology in conjunction with a high volume flow of the detergent solution.
By the liquid flow into the laundry container, the laundry mass moves in the direction of flow and is non-contact, pressed against a liquid-permeable support wall. The volume of pressurized laundry is greatly reduced. The liquor is discharged through the outlet into the tub and in turn transported by the high pressure pump back into circulation. The pressure level of the liquor is adapted to the laundry-specific requirements.

Nachdem der gewünschte Komprimierungsgrad der Wäsche erreicht wurde, wird die Laugenzuflussrichtung im Wäschebehälter gewechselt. Die Lauge wird in der Gegenrichtung zugeführt und die zuvor komprimierte Wäsche wird dabei durch die durchfließende Lauge entkomprimiert, gelockert und gegen die zweite, gegenüber der ersten liegende Stützwand erneut gepresst und komprimiert.
Die Laugenzuflussrichtung wird nach jeder Komprimierung zyklusartig gewechselt. Die Wäsche bewegt sich dadurch zwischen den beiden Stützplatten hin und her, wird zudem kontaktlos komprimiert, wieder gelockert und erneut komprimiert. Die Schmutzpartikel werden dabei aus der Wäsche ausgespült und abgeführt.After the desired degree of compression of the laundry has been achieved, the Laugenzuflussrichtung is changed in the laundry container. The liquor is supplied in the opposite direction and the previously compressed laundry is decompressed by the liquor flowing through, loosened and pressed against the second, opposite the first support wall again pressed and compressed.
The Laugenzuflussrichtung is cyclically changed after each compression. The laundry thus moves between the two support plates back and forth, is also compressed contactless, loosened again and compressed again. The dirt particles are flushed out of the laundry and removed.

Detaillierte Beschreibung einer bevorzugten Ausführungsform.Detailed Description of a Preferred Embodiment.

Der Waschvorgang wird im weiteren anhand einer bevorzugten Ausführungsform und in folgender Umgebung erläutert: die Seitenwand des Wäschebehälters 1 hat im wesentlichen die Gestallt eines Stumpfkegels und ist senkrecht zur seiner Längsachse positioniert, als Waschmittel wird eine Wasserlösung eingesetzt und die Entwässerungsphase wird mit Pressluft durchgeführt.The washing process is explained below with reference to a preferred embodiment and in the following environment: the side wall of the laundry container 1 has substantially the Gestallt a truncated cone and is positioned perpendicular to its longitudinal axis, as detergent, a water solution is used and the dewatering phase is carried out with compressed air.

Bei der vorliegenden Erfindung wird ein hochintensiver Laugenfluss durch die Wäschemasse hindurch durch Verwendung von Hochdrucktechnik in Verbindung mit einem hochvoluminösen Durchfluss der Waschmittellösung erreicht. Die erforderlichen Leistungsparameter für den Laugenzuflussumfang und die Druckhöhe werden hier mit hydraulischen Techniken ausgeführt. Die für einen wirkungsvollen Waschvorgang erforderliche Zirkulation der Lauge innerhalb der Wäschemasse wird dabei durch Flussrichtungswechsel der Lauge realisiert, die Wäsche wird zwischen den Stützplatten 3 und 4 hin und her bewegt und zudem kontaktlos komprimiert, wieder gelockert und erneut komprimiert.In the present invention, a high intensity liquor flow through the laundry mass is achieved by using high pressure technology in conjunction with a high volume flow of the detergent solution. The required performance parameters for the liquor inflow volume and the head are carried out here using hydraulic techniques. The circulation of the liquor within the laundry mass required for an effective washing process is realized by changing the flow direction of the liquor, the laundry is moved between the support plates 3 and 4 back and forth and also compressed contactless, loosened again and compressed again.

Die zu waschenden Wäschestücke werden bei geöffneter Kapsel 2 in den Behälter 1 eingelegt. Folglich wird die Kapsel 2 des Wäschebehälters 1 durch einen Verschließungs-Mechanismus 5 (z.B. durch ein Dreh- oder Klemmsystem) zu einer Funktionseinheit mit dem Behälter 1 druckdicht zusammengesetzt. Zur Erzeugung der Waschlauge 9 wird durch das Öffnen des Ventils 25 Frischwasser in den Behälter 8 zugeführt und nach Aktivierung des Flüssigkeitsumlaufs mit der Pumpe 7 wird es durch die Dosierungseinheit 24 mit vorzugsweise flüssigem Waschmittel versetzt. Die Waschlauge wird in den Behälter 1, vorzugsweise zunächst in Richtung von unten, nach Fig. 1 , gegen die Verjüngung des Behälters 1 und über das Leitungsrohr 11 zugeführt. Bei diesem Vorgang sind die Ventile 15, 18, und 19 geöffnet, die Ventile 16, 17, 20 und 21 sind dagegen geschlossen. Die Lauge wird durch das Saugrohr 10 mittels der Hochdruckpumpe 7 angesaugt und über das Rohr 11 in den Wäschebehälter 1 durch die siebartige oder dicht perforierte, vorzugsweise eine formstabile, untere Stützplatte 4, gepumpt. Durch den Laugenzufluss von unten wird die Wäsche überflutet und die sich in der Vorrichtung befindliche Luft wird nach außen verdrängt. Die Lauge geht durch die Fasern der Wäschestücke hindurch, und wird über das Leitungsrohr 23 und weiter durch das Leitungsrohr 12 in den Flüssigkeitsbehälter 8 ausgeschieden, durch das Saugrohr 10 von der Hochdruckpumpe 7 wieder zurück in Umlauf gebracht und durch die Leitung 11 in den Wäschebehälter 1 geführt. Durch den Strom wird die Wäsche 6 berührungslos nach oben bewegt und gegen die obere Stützplatte 3 gedrückt, die die gleichen Eigenschaften wie die untere Stützplatte 4 besitzt. Unter dem Hochdruck reduziert sich das Volumen der Wäsche stark.
Die Druckstärke, mit welcher das Wäschegut an die Stützwand gedrückt wird sowie die Dauer der Druckphase werden mit Hilfe des Steuergerätes der Pumpe 7 festgelegt. Die Laugentemperatur wird vorzugsweise mit Hilfe des Durchlauferhitzers 27 oder mit einem Heizelement, das in dem Flüssigkeitsbehälter 8 integriert ist, wäscheartabhängig, je nach Vorgabe, durch die Steuerung realisiert. Die Waschmittelkonzentration in der Lauge wird durch das Steuergerät 24 geregelt.
Nachdem die gewünschten Werte für den Komprimierungsgrad, das Durchlaufvolumen der Lauge und die Dauer der Waschphase erreicht wurden, wird die Laugenzuflussrichtung gewechselt.
Die Waschmittellösung wird jetzt in den Wäschebehälter 1 von oben ( Fig. 2 ) über das Leitungsrohr 23 gepumpt. Die Ventile 15, 18, 19 und 21 sind geschlossen, die Ventile 16, 17 und 20 sind dagegen geöffnet. Bei diesem Vorgang wird die Lauge in den Behälter 1 über die Leitungen 13 und 23 zugeführt und über die Leitungen 11 und 14 in den Flüssigkeitsbehälter 8 ausgeschieden, wo sie wiederum durch die Hochdruckpumpe 7 zurück in Umlauf gebracht und über die Leitung 23 in den Behälter 1 befördert wird. Die zuvor komprimierte Wäsche 6 gewinnt dadurch wieder an Volumen und bewegt sich in Stromrichtung nach unten, wird erneut sowohl gegen die untere Stützplatte 4 als auch gegen die Seitenwand des Behälters gepresst. Unter dem Hochdruck verschließen sich folglich auch die Räume zwischen der einzelnen Wäschestücken der Wäschemasse und die Lauge wird intensiv durch die Wäschemenge getrieben. Durch die Druckwirkung reduziert sich wiederholt das Volumen der Wäsche.
Durch die Komprimierung hat die Wäschemaße die Form des Wäschebehälters, d.h. eines Stumpfkegels, nach Art eines Korken eingenommen. Durch den erneuten Richtungswechsel des Laugenzuflusses bewegt sich die so geformte zusammengepresste Wäschemenge nach oben und dank der kegelförmigen Gestalt des Behälters bekommt die Wäsche sowohl in der Höhe als auch seitlich freien Raum zu Entkomprimierung. Die Zwischenräume der Wäsche vergrößern sich dabei wieder und unter einer intensiven Laugenzirkulation wird die Voraussetzung für das Wegtragen der vom Gewebe gelösten Schmutzpartikel geschaffen.
Die Laugenzuflussrichtung in den Wäschebehälter 1 wird nach jeder Komprimierung zyklusartig gewechselt und die Wäsche bewegt sich zwischen der Stützplatte 3 und der Stützplatte 4 hin und her, wird dabei kontinuierlich komprimiert, entkomprimiert und wieder komprimiert wird.The laundry items to be washed are inserted into the container 1 when the capsule 2 is open. Consequently, the capsule 2 of the laundry container 1 by a closing mechanism 5 (eg by a rotary or clamping system) to a functional unit with the container 1 pressure-tight. For generating the wash liquor 25 9 Fresh water is supplied into the container 8 by opening the valve, and after activation of the liquid in circulation to the pump 7, it is added by the dosage unit 24 preferably liquid laundry detergents. The wash liquor is in the container 1, preferably first in the direction from below, after Fig. 1 , fed against the taper of the container 1 and via the conduit 11 . In this process, the valves 15, 18, and 19 are opened, the valves 16, 17, 20 and 21 , however, are closed. The liquor is sucked through the suction pipe 10 by means of the high-pressure pump 7 and pumped via the pipe 11 into the laundry container 1 through the sieve-like or tightly perforated, preferably a dimensionally stable, lower support plate 4 . The leach inflow from below flooded the laundry and the air in the device is displaced to the outside. The liquor passes through the fibers of the laundry items, and is discharged through the conduit 23 and further through the conduit 12 into the liquid container 8 , brought back by the suction pipe 10 of the high pressure pump 7 back into circulation and through the line 11 into the laundry container. 1 guided. By the current, the laundry 6 is moved without contact upwards and pressed against the upper support plate 3 , which has the same properties as the lower support plate 4 . Under high pressure, the volume of laundry is greatly reduced.
The pressure with which the laundry is pressed against the support wall and the duration of the pressure phase are determined by means of the control unit of the pump 7 . The liquor temperature is preferably realized by means of the flow heater 27 or with a heating element which is integrated in the liquid container 8 , depending on the type of laundry, depending on the specification, by the controller. The detergent concentration in the liquor is controlled by the controller 24th
After the desired values for the degree of compression, the flow volume of the liquor and the duration of the washing phase have been reached, the liquor inflow direction is changed.
The detergent solution is now in the laundry container 1 from above ( Fig. 2 ) is pumped via the conduit 23 . The valves 15, 18, 19 and 21 are closed, while the valves 16, 17 and 20 are open. In this process, the lye in the Container 1 is supplied via the lines 13 and 23 and excreted via the lines 11 and 14 into the liquid container 8 where it is in turn brought back by the high-pressure pump 7 and conveyed via the line 23 into the container 1 . The previously compressed laundry 6 thereby regains volume and moves down in the flow direction, is again pressed against both the lower support plate 4 and against the side wall of the container. Consequently, the spaces between the individual laundry items of the laundry mass are also closed under high pressure, and the liquor is driven intensively through the amount of laundry. The pressure effect repeatedly reduces the volume of the laundry.
Due to the compression of the laundry measures the shape of the laundry container, ie a truncated cone, taken in the manner of a cork. Due to the renewed change of direction of the Laugenzuflusses the so-shaped compressed laundry amount moves up and thanks to the conical shape of the container gets the laundry both in height and laterally free space to decompress. The interstices of the laundry increase again and under an intensive liquor circulation, the condition for the removal of the dirt particles dissolved by the tissue is created.
The Laugenzuflussrichtung in the laundry container 1 is cyclically changed after each compression and the laundry moves between the support plate 3 and the support plate 4 back and forth, it is continuously compressed, decompressed and compressed again.

Nachdem die Wäsche gewaschen ist, wird die Lauge aus dem Behälter 1 über den Laugenbehälter 8 durch den Abfluss 26 nach außen abgelassen. Die Ventile 17, 19 sind geöffnet, die Ventile 18, 20 und 21 sind dagegen geschlossen.
Zur Entwässerung wird bei geschlossenen Ventilen 18, 19 und 20 in den Behälter 1 durch das Leitungsrohr 23 aus einem internen Luftkompressor 22 oder einer externen Quelle gepresste Luft zugeführt. Die Luft verdrängt die Lauge aus der Wäsche in den Behälter 8. Der Zeitpunkt, die Luftdruckhöhe und die Dauer des Entwässerungsvorgangs werden durch das Steuergerät des Luftkompressors 22, wäscheartabhängig geregelt.
Danach wird der Spülvorgang, so wie der Waschvorgang durchgeführt, mit dem Ziel, die Lauge aus der Wäsche auszuspülen, bis der gewünschter Effekt erreicht ist.After the laundry is washed, the liquor is drained from the container 1 through the tub 8 through the drain 26 to the outside. The valves 17, 19 are open, the valves 18, 20 and 21 , however, are closed.
For dewatering, when the valves 18, 19 and 20 are closed , air is supplied to the container 1 through the conduit 23 from an internal air compressor 22 or an external source. The air displaces the liquor from the laundry into the container 8. The time, the air pressure level and the duration of the dewatering process are regulated by the control unit of the air compressor 22, depending on the type of laundry.
Thereafter, the rinsing process, as the washing process is carried out, with the aim of rinsing the liquor from the laundry until the desired effect is achieved.

Der letzte Spülvorgang kann mit einem Zusatz von Spülmittel aus der Dosierungseinheit 24 durchgeführt werden. Nachdem die Wäsche ausgespült wurde, wird das Spülwasser aus dem Laugenbehälter 8 über den Abfluss 26 abgelassen. Zur Entwässerung wird wieder durch den Luftkompressor 22 gepresste Luft in den Wäschebehälter 1 hinzugeführt und folglich kann die tropffreie Wäsche aus dem Behälter 1 entnommen werden.The last rinsing process can be carried out with an addition of rinsing agent from the dosing unit 24 . After the laundry has been rinsed out, the rinse water is drained from the tub 8 via the drain 26 . For dewatering compressed by the air compressor 22, air is added into the laundry out container 1 again, and thus the drip-free laundry can be removed from the container. 1

Claims (10)

  1. Device for treating textiles, characterised in that the items of laundry (6) disposed in a high-pressure-capable container (1) are exposed to a high-intensity flow of wash liquor from below via a pipe (11) through a liquid-permeable support plate (4) using high-pressure technology in conjunction with a high-volume throughflow of detergent solution (9) through the mass of laundry, which is performed using hydraulic technologies, as a result of which the liquor flowing through the laundry moves the mass of laundry (6) in the flow direction and presses and compresses in a non-contact manner against a liquid-permeable support plate (3), and the liquor is thus discharged through a pipe (23) and a pipe (12) into the container (8) and is conveyed again by means of the high-pressure pump (7) back into circulation via the conduit pipe (11) into the container (1).
  2. Device for treating textiles according to claim 1, characterised in that once the laundry has reached the desired degree of compression, the liquor inflow direction into the container (1) is changed and is fed from above through the pipe (23) through the liquid-permeable support plate (3), as a result of which the previously compressed mass of laundry (6) is decompressed, loosened and pressed and compressed again against the support plate (4) and the liquor is thus discharged through the pipes (11) and (14) into the container (8) and conveyed again by means of the high-pressure pump (7) back into circulation via the conduit pipe (23) into the container (1).
  3. Device for treating textiles, characterised in that the process according to claim 1 and the process according to claim 2 is repeated cyclically, as a result of which the mass of laundry (6) moves to and fro between two oppositely positioned support plates (3) and (4) and is, in this way, continuously compressed, decompressed and compressed again.
  4. Device for treating textiles according to one of the preceding claims, characterised in that the container (1) is high-pressure resistant, its side wall essentially has the shape of a truncated cone or a parabolic, elliptical or other preferably rotationally symmetrical construction, in an alternative embodiment it is embodied with at least one internally moulded throttle sleeve (28) and preferably consists of a transparent material.
  5. Device for treating textiles according to one of the preceding claims, characterised in that for filling with or removing laundry, the laundry container (1) has at least one inlet, preferably positioned in its upper part, in the form of a capsule (2) or another expedient, alternatively also laterally positioned inlet, which is combined with a closing mechanism (5) to form a high-pressure-capable functional unit with the laundry container (1).
  6. Device for treating textiles according to one of the preceding claims, characterised in that the liquid-permeable support plates (3) and (4) are sieve-like, porous or otherwise tightly perforated, have a preferably form-stable construction, and are fixedly integrated in the laundry container or function as an insert.
