Definitions

  • the present invention relates to a drum for washing machines and / or centrifugal centrifuges according to the preamble of independent claim 1, as well as a use in washing machines according to the preamble of independent claim 10 and a use in dry centrifuges according to the preamble of independent claim 11.
  • these webs can be designed such that they reinforce the one drum wall on which the bearing journal is held. In addition, they also serve to cause a movement of the liquor and the items to be washed when the drum rotates during the washing process.
  • drums in washing machines are used as centrifuges to dry the laundry, then one drum works diameter of 475 mm and a speed of 1100 rpm an acceleration of 320 G on the laundry.
  • accelerations of 740 G act on the laundry at 1400 or 1200 rpm.
  • 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 carrier webs should be smaller than the greatest centripetal force that occurs, but greater than a centripetal force at a lower speed than the decay speed, such as the loosening speed or the washing speed.
  • the height of the driver webs should be about 1/10 of the drum diameter in the case of large centrifugal centrifuges, and that it can be relatively larger in household washing machines in order to ensure good flexing of the laundry in the fleet.
  • 1/8 to 1/12 of the drum diameter can be specified for the height of the driver webs.
  • a preferred use of such a drum is in large-scale washing systems with a clocked washing process, in which the laundry is introduced from the unclean side into a washing tube and washed on the opposite clean side is fed to a drying system. Because these systems mostly work automatically, the use of this drum has a special advantage.
  • 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 driven in rotation 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 to a support frame, not shown, in the usual way.
  • 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 axis of the drum lies horizontally. In this position, the speed is increased to the usual spin speed of 900 to 1200 rpm. The items to be washed are pressed against the drum wall 24. As a result of 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 loosened.
  • 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 shown in that after switching from the high spin speed to the loosening speed, the tubular compressed laundry 6 according to FIG. 2 by the restoring force of the carrier webs 2-5 is loosened so that no additional aids such as compressed air or the like are required to remove the laundry from the drum.
  • the driver webs must be larger in relation to the drum diameter than in the centrifugal centrifuge, so that the laundry is taken along at the washing speed. If the spin speed is switched over here, the driver webs are also pressed together, so that the laundry is relaxed when it is pressed against the drum wall and, as the speed decreases, the laundry is detached from the drum wall and can fall off, so that the laundry loosens out can be removed from the drum.
