Definitions

  • the invention relates to a washing machine or a washer-dryer with an in a tub horizontal or inclined and rotatable drum with a jacket and two cover surfaces, the jacket or one of the cover surfaces with a removal opening is equipped, and wherein the jacket is wholly or partly made of sheet metal, which is provided with a domed structure facing the inside of the drum.
  • Drums of washing machines or washer dryers usually consist of sheet metal structures. Because of the high spin speeds of up to 1600 rpm, the drum construction great demands are placed on strength, shape retention and rigidity. It is known from DE 44 37 986 A1 and from DE-OS 25 57 215, the sheet metal which the drum is manufactured to provide with arched structures to increase its strength.
  • the drum jacket and possibly also the top surfaces are provided with holes so that an exchange of lye between the laundry and the tub is possible is guaranteed.
  • These holes have diameters in today's washing machines in the order of 3.5 mm.
  • the drum First punch holes with a diameter of approx. 2.5 mm in a sheet metal coil and then through a stamping process, the so-called penetration, deepened in a funnel shape and widened to 3.5 mm.
  • the recess of the holes is directed outwards in a cylindrical jacket. This happens for the purpose that any burrs on the edge of the hole do not protrude into the inside of the drum and so the contact of the laundry to these ridges is avoided.
  • a washing machine is known from US Pat. No. 2,591,143, the drum of which has a curvature in Form of a corrugation extending over the entire length of the drum shell is.
  • the perforated drum is arranged in the outwardly directed recesses. This leads to residual water in the flat areas between the holes stops and drainage deteriorates. In addition, such a drum structure the laundry is rubbed very badly and thereby damaged.
  • Drums with hole diameters around 2 mm which do not have to be put through, therefore have a relatively smooth surface, which has the optical properties described above absence.
  • the invention therefore presents the problem of designing the drum of a washing machine in such a way that that at the same time good optical properties and complete emptying of the Residual water can be reached.
  • the holes are compared to those of conventional drum washing machines are reduced in number and / or in diameter. This is the passage reduced by fluff or threads, which is more gentle on the laundry.
  • the drum washing machine (1) designed according to the invention has a tub (2) in which a drum (3) for receiving laundry (4) is rotatably mounted.
  • the drive the drum (3) is driven by a motor (13) via a V-belt (13.1).
  • the tub (2) is swingably suspended on springs (5) in the housing (6) and becomes Damping of these vibrations in the lower area by shock absorbers (7) compared to Supported base (8).
  • the detergent / fabric softener required to carry out a washing program will be the Suds container (2) via a detergent dispenser (9) with connected connecting hose (10) fed.
  • a detergent dispenser 9 with connected connecting hose (10) fed.
  • the desired substances can be added by the user
  • Corresponding compartments (11) of a detergent drawer (12) can be filled. About an in the water supply, not shown, the entire subject at the beginning of of the respective program part washed into the tub (2).
  • a microprocessor control is used to control the different washing programs provided that via signal lines (14) with various sensors and the controls connected is. It issues time and status-dependent commands via control lines (15) to various actuators (motors, valves, display elements ).
  • the drum (3) is in an automatic manufacturing process described in more detail elsewhere (not shown). This is done first for the drum jacket (3.1) cut a metal strip from a coil and punch it with the desired one Provide perforation (16). The sheet metal strip is then bent in a circle and welded the two mutually facing edges. The resulting cylinder is provided with shaping and stabilizing contours by known expansion processes. Then a vaulted structure is created by a method known from DE-OS 25 57 215 put on the coat. Then the floor (3.2) and the Cap (3.3).
  • Figure 3 shows a section of the drum shell (3.1) with the basic structure of the Arch structure and the arrangement of the holes (16) according to the invention:
  • the jacket (3.1) is preferably in sections with inwardly curved polygons Hexagons (17).
  • the arrangement of the holes (16) is determined by the requirement for rapid, residue-free Water drainage and good degree of textile drainage when spinning with pumps or only pumping, optimal laundry protection, low foreign body sensitivity and good looks.
  • Rows of holes are on the front and rear edges (3.5) of the drum shell (3.1) are not arched. Additionally or alternatively, there are more limited, unstructured ones Zones (3.6) with holes (16) possible, for example as shown in Figure 3, in the middle of the drum casing (3.1).
  • the domed areas can be completely be unperforated so that the structure only serves to secure the drum (3), but it can also the perforation (16) described above in the preferred locations within the Vaulted structure, e.g. B. the corner points (20) of the polygons (17).
  • the diameter of the drum (3) can be the same with a suitable material thickness
  • Tub diameter can be increased by up to 10 mm, if not one Prevents water jacket formation when spinning. This allows the smallest distance between the drum casing (3.1) and the tub container is only approx. 5 mm.
  • Drum jackets (3.1) can be provided with the arch structure as cylinders and before or afterwards subjected to a further forming process (e.g. expansion).
  • a further forming process e.g. expansion
  • it is possible to produce finished circuit boards or coil material with curved structures see DE 44 37 986 A1
  • punch before or after and undergo further forming processes e.g. roll forming, embossing, pressing, etc.
  • further forming processes e.g. roll forming, embossing, pressing, etc.
