Definitions

  • the invention relates to a washing machine with a housing, the an upper loading opening and a lower unloading opening and in which a rotating around a horizontal axis Drum is mounted, the cylindrical wall openings for Loading and unloading, one by one horizontal axis pivotable flap is associated with an automatic opening and closing mechanism connected is.
  • the pelvic discharge flap is on the side; from it follows that both the drum and the cymbal on one certain height must be attached to the pool There is space for the car to catch the washed laundry.
  • Washing machines are according to the preamble of claim 1 known from DE-A 28 22 983.
  • Figures 1 and 2 a prior art known at the time, according to which the flaps of the drum directly on the cylinder wall were articulated. This has the disadvantage that the rotation of the Due to the centrifugal force the flaps open and the Can destroy the washing machine.
  • Figures 3 and 4 the flaps not on the cylinder jacket of the drum, but on Axes that are mounted further inside on partitions. The Flaps are then only so far in the open position outside that they no longer touch the wall of the housing can. - About loading the loading openings of the The housing and the unloading of the drum are not specified made.
  • no measures are provided that Lock the flaps in the closed state so that when Strains in the circumferential direction of the drum popping open Flaps is prevented; in such a case the Items of laundry over the loading opening and the unloading opening fall out.
  • the subject of GB-A 2 124 662 is a washing machine with a Loading and unloading opening on the front of the drum without automatic loading or emptying is provided there is.
  • the invention has for its object a washing machine train that mechanized loading and unloading can be carried out, at the same time in the loaded Condition of the rotating drum which remains securely closed.
  • Claim 1 To solve this problem is according to the characteristic of Claim 1 provided that under the discharge opening of the Housing a conveyor belt for the washed laundry is arranged with a lifting element during the loading opening a vertically displaceable one and above the loading opening tiltable loading basket is assigned, the opening and Locking mechanism for the on the cylindrical wall of the drum mounted flaps acting both radially and axially parallel Has locking elements.
  • the new washing machine has an openwork drum that extends located inside a cylindrical basin and on one horizontal axis of rotation is attached.
  • the cylindrical Cymbals and the drum have one or more flaps that face each other located on the cylindrical surface.
  • All inner and outer folding doors of the washing machine, the Beckens and the drum can be mechanical, oleodynamic or pneumatic systems opened, closed and locked become; these systems become electronic or electromechanical controlled.
  • the unloading flaps are closed Loading flaps opened and the lifting device of the baskets in Movement set so that the laundry items in the washing machine fall. Then the loading flaps close; in the Washing machine flows water and possibly detergent, Whitener, fabric softener and. a. Solid materials used for Washing can be used, such as pumice or Floodstone, together with the clothes, are directly in the loading baskets or placed in the boats. If the selected washing cycle is finished, the drum is stopped Conveyor belt starts to move, and the lower unloading door opens so that the washed laundry items fall out.
  • an electronic system determines whether the load of the laundry items while rotating exert eccentric forces that are strong for the washing machine can be harmful. Should the laundry load on a Have accumulated side, so it causes electronic Control system slowing down and / or braking the Rotation, possibly several times, as often, until the load balanced during the spin cycle.
  • the basin loading and unloading baskets are hinged to the longitudinal edges attached and are by means of hydraulic winches opened and closed.
  • the loading and Unloading flaps of the drum are hinged to the longitudinal edges attached, but they are marked by a special pneumatic and mechanical system opened and closed.
  • the flaps of the pool have to be watertight be and the burdens of the moving Withstand water; on the flaps of the rotating drum, however the rotational force acts during the skidding, which is the danger in hides that the drum edge changes and one The flap opens. To counteract this, are holes and on the drum flap edge opposite the hinge Grooves are provided at an even distance.
  • crank lever At the same height as the hinge there is a one-piece crank lever on the flap.
  • Two rotating arms with cams which are attached to the pool by means of hinges and in accordance with the loading and unloading flap, open and close the rotating drum.
  • To open the flap of the rotating drum one has to operate the cam arm and turn the drum so that the crank lever of the flap fits into the cam of the arm; then the rod is adjusted with the teeth by means of a pneumatic piston so that the teeth are in line with the grooves on the edge of the flap.
  • the cam arms are rotated and in turn the crank lever of the drum flap also rotates so that the drum opens.
  • the washing machine can also serve as a centrifuge. It exists hence the possibility of an automated system to be provided from a range of washing machines and by Slingshots exist, which consist of movable baskets for loading and operated for emptying.
  • the cylindrical basin V with a horizontal axis is by means of a pneumatic suspension S from a metal structure T held.
  • An electric motor M that with a Reduction gear R is provided, causes the rotation of the inner drum.
  • the basin V is equipped at the top with loading flaps P1 and at the bottom with unloading flaps P2.
  • a conveyor belt N which tilts the washed laundry items that fall out of the unloading flap P2 into a collection basket.
  • a lifting system E On the side of the basin V there is a lifting system E, which lifts and tilts the loading baskets Cc, so that the items to be washed fall inside the rotating drum.
  • FIG. 2 shows the opening and closing mechanism of the flaps during the most important moments when opening.
  • the rotary drum 2 is provided with a flap 3, which is attached by means of a hinge on one of the long sides 4 parallel to the axis of rotation of the drum 2.
  • the flap On the hinge 4 the flap has a crank lever 5 and on the opposite edge 12 there are holes 11a and grooves 13. Opposite the flap hinge 4, on the side of the hole, there are 2 elevations 11b and a rod 10 with teeth on the drum 10a.
  • the rod 10 provided with teeth 10a is mounted parallel to the axis of rotation of the drum 2 and can be moved along the axis on rails provided for this purpose; the teeth 10a are attached to the rod so that they protrude at right angles, the distance to the drum is as large as the thickness of the flap 3 or only slightly larger.
  • a rotating arm 6, which is provided with cams 6 is on inner pool edge 1 fastened by hinge. He is through a hydraulic crank lever 7, which is outside the Beckens 1 is pressed.
  • Figure 3 shows a system with baskets and boats 21, 22 for Loading and unloading (24) with washing machines 23, Connecting members 25, feeders 26 and separators 27 of pumice or detergents, a conveyor belt 28 for the Loading the slingshot 34, a conveyor 29 for the supply of Pumice, a container 30 for pumice, a lifting system 31 for pumice, a dosing device 32 for pumice, an addition boat 33 for pumice, slingshots 34 and dryers 35.
