Definitions

  • a washing system 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.
  • 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.
  • this requires a relatively large outlay on equipment and a rigid arrangement of the spinner housing.
  • the object of the invention is to eliminate these disadvantages. This object is achieved with the characterizing features of claim 1.
  • 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.
  • 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.
  • 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.
  • 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.
  • the height of the driver webs should be about 1/10 of the drum diameter for large centrifuges.
  • 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.
  • a collecting funnel 31 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.

Claims (10)

1. Installation de lavage comprenant un tube de lavage (10) avec une ouverture de chargement à une extrémité et une trémie de décharge (II) à l'autre extrêmité, avec un processus de lavage cadencé et un cycle de décharge automatique, dans laquelle la trémie de décharge (II) débouche contre un tambour d'essoreuse (21), qui présente deux fonds de tambour (22, 23) écartés l'un de l'autre, reliés entre eux par une paroi de tambour perforée comme une passoire (24), dont l'un présente une ouverture de chargement (29) et l'autre est disposé pour porter un tourillon (26) servant à la suspension rotative du tambour (21), caractérisée par le fait que le tambour (21) est logé dans un carter (23) qui peut basculer sur un coussinet de pivotement (30) au-dessus de la paroi avant du tambour (22) vers l'ouverture de chargement (29), de telle sorte que dans une première position de travail, le tambour (21) tournant lentement, l'ouverture de chargement (29) touche la trémie de livraison (II) de la machine à laver (10), pourque le linge puisse être avancé à l'aide de l'eau pour rincer, que dans une deuxième position de travail, dans laquelle l'axe du tambour est horizontal, le tambour (21) puisse tourner à grande vitesse, et que dans une troisième position de travail il puisse être amené dans une position de déchargement, avec l'ouverture de chargement (29) tournée vers le bas, dans laquelle les pièces de linge sont détachées de la paroi du tambour (24) à la vitesse de relâchement, et que la paroi du tambour présente plusieurs traverses d'entraînement (2-5) constituées de bosses en forme d'U disposées parallèlement à son axe de rotation, qui sont en un matériau élastique, au moins dans leur partie arrière.
2. Installation de lavage suivant la revendication 1, dans laquelle le tambour, dans la deuxième position de travail indiquée, peut être entraîné à une vitesse d'essorage et à une vitesse de relâchement, caractérisée par le fait que la force de rappel du matériau élastique des traverses (2-5) est calculée de telle sorte, que le linge pressé contre la paroi du tambour (24) à la vitesse d'essorage soit détaché de la paroi du tambour à la vitesse de relâchement par suite de la force de rappel élastique de la paroi du tambour (24).
