Description

Eine Waschanlage gemäss Oberbegriff des Anspruchs 1 ist aus DE-A-2 801 594 bekannt. Es handelt sich dabei um eine Grosswaschanlage, bei welcher die schmutzige Wäsche am einen Ende einer Waschröhre durch eine Beschickungsöffnung eingegeben wird und hierauf in der Waschröhre mehrere Vorwasch-, Wasch- und Spülzyklen in je dafur vorgesehenen Kammern durchläuft. Am andern Ende der Waschröhre wird jeweils beim Weiterschalten des Zyklus eine Charge sauberer Wäsche über einen Ausgabetrichter in eine Schleudertrommel entladen, in welcher die Wäsche bügelfertig trockengeschleudert wird. Durch die grossen dabei auftretenden Zentrifugalkräfte klebt anschliessend die getrocknete Wäsche an der Trommelwand.A washing system according to the preamble of claim 1 is known from DE-A-2 801 594. It is a large-scale washing system in which the dirty laundry is entered at one end of a washing tube through a loading opening and then goes through several pre-washing, washing and rinsing cycles in the compartments provided for this purpose in the washing tube. At the other end of the washing tube, a batch of clean laundry is unloaded via an output funnel into a centrifugal drum in each cycle of the cycle, in which the laundry is spin-dried and ready for ironing. Due to the large centrifugal forces that occur, the dried laundry then sticks to the drum wall.

Um dieses Problem zu lösen, schlägt DE-A-2 801 594 vor, die Trommel nach dem Schleudern entweder von aussen mit Ueberdruck oder von innen mit Unterdruck zu beaufschlagen. Dazu ist jedoch ein relativ grosser apparativer Aufwand und eine starre Anordnung des Scheudergehäuses erforderlich.In order to solve this problem, DE-A-2 801 594 proposes to apply positive pressure to the drum either from the outside or from the inside with negative pressure after spinning. However, this requires a relatively large outlay on equipment and a rigid arrangement of the spinner housing.

Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu beseitigen. Diese Aufgabe wird mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.The object of the invention is to eliminate these disadvantages. This object is achieved with the characterizing features of claim 1.

Es ist zwar aus DE-C 923 247 und aus DE-U 1 963 811 bei Haushaltwaschmaschinen mit kombinierten Wasch- und Schleudertrommein bekannt, die in solchen Maschinen notwendigen Mitnehmerstege elastisch auszubilden, um am Ende des Schleudervorgangs die Wäsche von der Trommelwand zu lösen. Diese Massnahme wurde jedoch bisher nicht auf reine Schleudertrommeln angewandt, weil diese normalerweise keine oder nur sehr niedrige Mitnehmerstege aufweisen.It is known from DE-C 923 247 and from DE-U 1 963 811 in household washing machines with combined washing and centrifugal drums to elastically form the entraining webs necessary in such machines in order to detach the laundry from the drum wall at the end of the centrifuging process. However, this measure has not previously been applied to pure centrifugal drums, because they normally have no or only very low driver webs.

Die erfindungsgemässe Anwendung dieser Massnahme in einer Maschine gemäss Oberbegriff des Anspruchs 1 ermöglicht es, das Schleudergehäuse kippbar anzuordnen und dadurch die Entleerung der Trommel zu beschleunigen und zu erleichtern.The inventive application of this measure in a machine according to the preamble of claim 1 makes it possible to arrange the centrifuge housing in a tiltable manner and thereby to accelerate and facilitate the emptying of the drum.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung beschrieben. Es zeigen :

  • Figur 1 eine Schnittansicht einer Trommel gemäss einer Schnittebene senkrecht zur Trommelachse in ruhendem Zustand,
  • Figur 2 eine Schnittansicht ähnlich derjenigen gemäss Fig. 1, jedoch mit den Mitnehmerstegen in einer Betriebsphase,
  • Figur 3 bis Fig. 5 je einen Aufriss einer Taktwaschanlage mit einer Schleuderzentrifuge mit einer Trommel nach Fig. 1 in drei verschiedenen Betriebslagen.
An embodiment of the invention is described below with reference to the drawing. Show it :
  • FIG. 1 shows a sectional view of a drum according to a sectional plane perpendicular to the drum axis in the stationary state,
  • FIG. 2 shows a sectional view similar to that according to FIG. 1, but with the driver webs in an operating phase,
  • 3 to 5 each show an elevation of a cycle washing system with a centrifugal centrifuge with a drum according to FIG. 1 in three different operating positions.

Die siebartig gelochte Trommelwand 1 ist gemäss Fig. 1 mit vier auf dem Umfang verteilt angeordneten Mitnehmerstegen 2-5 versehen. Diese Mitnehmerstege bestehen aus einem elastischen Material, vorzugsweise aus einem künstlichen Kautschuk, der mit den Waschmitteln nicht reagiert. Gemäss der dargestellten Form sind diese Mitnehmerstege 2-5 aus einem rohrartigen Profil hergestellt. Sie könnten aber auch mit einem weichelastischen Schaumgummi ganz oder teilweise ausgefüllt sein.According to FIG. 1, the drum wall 1 perforated in the form of a sieve is provided with four driver webs 2-5 arranged distributed over the circumference. These carrier webs consist of an elastic material, preferably of an artificial rubber, which does not react with the detergents. According to the shape shown, these driver webs 2-5 are made from a tubular profile. But you could also be completely or partially filled with a soft elastic foam rubber.

Die Rückstellkraft der gummielastischen Mitnehmerstege sollte je nach Verwendung in den verschiedenen Maschinen kleiner sein als die grösste auftretende Zentripetalkraft, aber grösser sein als eine Zentripetalkraft bei einer geringeren als der Ausschwingdrehzahl, wie beispielsweise der Lockerungsdrehzahl.Depending on the use in the various machines, the resetting force of the rubber-elastic driver webs should be smaller than the greatest centripetal force that occurs, but greater than a centripetal force at a lower than the decay speed, such as the loosening speed.

Damit wird erreicht, dass bei erhöhter Zentripetalkraft die Mitnehmerstege einsinken und dadurch der Zug auf das Waschgut verringert wird, und dass bei geringerer Drehzahl, wie der üblichen Lockerungsdrehzahl, die Wäsche durch die Rückstellkraft der gummielastischen Stege von der Trommelwand gelöst wird und ohne weitere Massnahmen infolge der Schwerkraft nach unten fallen kann.This ensures that when the centripetal force is increased, the driver webs sink in, thereby reducing the tension on the items to be washed, and that at a lower speed, such as the usual loosening speed, the laundry is released from the drum wall by the restoring force of the rubber-elastic webs and without any further measures as a result gravity can fall down.

Es hat sich gezeigt, dass die Höhe der Mitnehmerstege bei grossen Schleuderzentrifugen etwa 1/10 des Trommeldurchmessers sein sollte.It has been shown that the height of the driver webs should be about 1/10 of the drum diameter for large centrifuges.

Die erfindungsgemässe Verwendung einer solchen Trommel ist bei Grosswaschanlagen mit getaktetem Waschvorgang, bei dem die Wäsche von der unreinen Seite her in eine Waschröhre eingeführt wird und auf der gegenüberliegenden reinen Seite gewaschen einer Trockenanlage zugeführt wird. Weil diese Anlagen meist selbsttätig arbeiten, hat die Verwendung dieser Trommel einen besonderen Vorteil.The use of such a drum according to the invention is in large washing systems with a clocked washing process, in which the laundry is introduced into a washing tube from the unclean side and washed on the opposite clean side and fed to a drying system. Because these systems usually work automatically, the use of this drum has a special advantage.

Gemäss Fig. 3-5 wird der Ablaufzyklus eines Trockenvorganges skizziert. Von einer Waschröhre 10 ist die Ausgabeseite mit dem Abgabetrichter 11, der Laufschiene 12 und einer Schleuse 13 schematisch im Schnitt dargestellt. Eine Schleuderzentrifuge 20 mit einer Trommel 21 mit zwei Trommelböden 22, 23 und einer Trommelwand 24 ist in einem Laugenbehälter 25, der in einem Gehäuse 33 elastisch aufgehängt ist, drehbar gelagert und wird durch einen Antriebsmotor 27 und einen Riemenantrieb 28 am Lagerzapfen 26 rotierend angetrieben. Das Gehäuse 33 ist an einer Stelle im Gebiet über der Trommelwand 22 an einer Drehachse 30 kippbar gelagert. Die Drehachse kann in üblicher Weise an einem nicht dargestellten Stützgestell befestigt sein.3-5, the sequence cycle of a drying process is outlined. The output side of a washing tube 10 with the discharge funnel 11, the running rail 12 and a lock 13 is shown schematically in section. A centrifugal centrifuge 20 with a drum 21 with two drum bottoms 22, 23 and a drum wall 24 is rotatably mounted in a tub 25, which is elastically suspended in a housing 33, and is rotatably driven by a drive motor 27 and a belt drive 28 on the journal 26. The housing 33 is tiltably mounted at one point in the area above the drum wall 22 on an axis of rotation 30. The axis of rotation can be attached in the usual way to a support frame, not shown.

Unterhalb des Gehäuses 33 befindet sich ein Auffangtrichter 31 und unter diesem ein Förderband 32. Anstelle des Förderbandes könnte auch eine Förderwagenanlage vorgesehen sein.Below the housing 33 there is a collecting funnel 31 and below this a conveyor belt 32. A conveyor system could also be provided instead of the conveyor belt.

In der gegenseitigen Stellung von Waschröhre 10 und Schleuderzentrifuge 20 wird das Waschgut mit einem Teil des Spülwassers in die Trommel 21 hineingeführt. Die Trommel 21 kann dabei mit einer Verteildrehzahl rotiert werden, damit das Waschgut sich auf dem gesamten Umfang verteilen kann.In the mutual position of the washing tube 10 and centrifugal centrifuge 20, the items to be washed are introduced into the drum 21 with part of the rinsing water. The drum 21 can be rotated at a distribution speed so that the laundry can be distributed over the entire circumference.

In der zweiten Phase gemäss Fig. 4 wird das Gehäuse 33 in eine Lage gekippt, bei der die Achse der Trommel horizontal liegt. In dieser Stellung wird die Drehzahl auf die übliche Schleuderdrehzahl von 900 bis 1 200 U/min erhöht. Dabei wird das Waschgut gegen die Trommelwand 24 gepresst. Infolge der Anpresskraft werden die gummielastischen Mitnehmerstege zusammengedrückt. Nachdem der Wassergehalt auf die zum Bügeln notwendige Restfeuchtigkeit verringert wurde, wird die Drehzahl auf eine viel geringere Lockerungsdrehzahl verringert.In the second phase according to FIG. 4, the housing 33 is tilted into a position in which the The axis of the drum is horizontal. In this position, the speed is increased to the usual spin speed of 900 to 1,200 rpm. The items to be washed are pressed against the drum wall 24. As a result of the contact pressure, the rubber-elastic carrier webs are pressed together. After the water content has been reduced to the residual moisture required for ironing, the speed is reduced to a much lower loosening speed.

Indem die Zentripetalkraft dabei nachlässt, kann die Rückstellkraft des elastischen Materials der Mitnehmerstege das Waschgut von der Trommelwand lösen, so dass die Wäsche gelickert wird.Because the centripetal force decreases, the restoring force of the elastic material of the driver webs can detach the laundry from the drum wall, so that the laundry is leaked.

In der Phase 3 gemäss Fig. 5 wird das Gehäuse 33 nach hinten gekippt, so dass die Achse der Trommel 21 einen spitzen Winkel mit der Horizontalen einschliesst und die Einfüllöffnung 29 gegen den Auffangtrichter 31 gerichtet ist. Mit einer Rotation mit der Lockerungsdrehzahl fällt die Wäsche nach unten und kann durch die Einfüllöffnung 29 in freiem Fall in den Auffangtrichter 31 und weiter zur Förderbandanlage 32 gelangen.In phase 3 according to FIG. 5, the housing 33 is tilted backwards so that the axis of the drum 21 forms an acute angle with the horizontal and the filling opening 29 is directed against the collecting funnel 31. With a rotation at the loosening speed, the laundry falls down and can freely pass through the filling opening 29 into the collecting funnel 31 and on to the conveyor belt system 32.

Bei einem solchen Ablauf zeigt sich der Vorteil der vorgeschlagenen elastischen Mitnehmerstege 2-5 deutlich, indem nach dem Umschalten von der hohen Schleuderdrehzahl auf die Lockerungsdrehzahl die rohrförmig zusammengepresste Wäsche 6 gemäss Fig. 2 durch die Rückstellkraft der Mitnehmerstege 2-5 gelockert wird, so dass keine zusätzlichen Hilfsmittel wie Pressluft oder dergleichen benötigt werden, um die Wäsche aus der Trommel zu entfernen.With such a sequence, the advantage of the proposed elastic carrier webs 2-5 is clearly evident in that after switching from the high spin speed to the loosening speed, the tubular compressed laundry 6 according to FIG. 2 is loosened by the restoring force of the carrier webs 2-5, so that no additional aids such as compressed air or the like are required to remove the laundry from the drum.
