Definitions

  • the present invention relates to drum washing machine with a laundry drum for the laundry, the laundry drum having at least one drum jacket has, in the passage openings for the alkali and / or on the inner surface thereof Elevations pointing towards the axis of rotation are formed, which increase with Alternate wells.
  • washing machines have been used extensively for washing and caring for a wide variety of consumer textiles. In many private households, the washing machine is an essential commodity with high requirements. A modern washing machine should be environmentally compatible, consume as little energy as possible and also achieve excellent washing performance. The washing performance was largely optimized in combination with increased detergent quality and favorable dosage.
  • wear of the laundry items cannot be completely prevented, especially with frequent washing of everyday textiles. which is made of high-quality, for example breathable textile fibers, justifies a high purchase price in terms of protecting the fibers, especially expensive items of laundry can be improved.
  • the wear of the laundry items during the spin cycle is caused above all by the mechanical loading of the laundry items at the passage openings (so-called flood holes) in the drum jacket.
  • washing machines of the prior art penetrates during the washing process Wash liquor from the tub through a variety of openings in the drum jacket into the inside of the laundry drum. Through the same openings the wash liquor leaves the drum while pumping and Fling.
  • the inside of the Drum jacket cylindrical and evenly formed and only by the Passages interrupted.
  • the tulip-shaped openings have sharp cut edges outside of the drum and can Spin Threats to the fibers of the laundry items pressed through them.
  • DE 44 37 986 A1 describes a method for structuring the curvature of thin material webs and films proposed that also for the manufacture of a drum shell Washing machines can be used. This procedure uses thin Material webs or foils over a support contour roller, on which staggered, square or hexagonal support elements are attached, guided and then vaulted in its surface due to external overpressure or internal underpressure.
  • DE 44 37 986 A1 thus describes a forming process in which a Bending deformation of the material takes place with a very low material shrinkage. There are curvatures in the material web that act as vaulted structures or Indentations.
  • a disadvantage of this prior art method is in particular that material surfaces only slightly dented. Especially for manufacturing of a drum jacket for a washing machine has the method of DE 44 37 986 A1 has considerable disadvantages.
  • a drum jacket made in this way does not allow efficient protection of the textile fibers, especially when spinning, because the laundry items with the sharp edges of the passage openings still in Come into contact and the mechanical fiber damage can not be prevented can.
  • the present invention is therefore based on the object of a drum washing machine to propose a quick removal of the during the spinning Wash liquor enables and the mechanical damage to the textile fibers is evident is reduced or avoided entirely.
  • the laundry drum advantageously has a substantially cylindrical shape on.
  • the wash liquor to be removed is evenly distributed the inside of the drum shell, which ensures a maximum discharge of the Wash liquor is reached from the laundry drum.
  • the laundry drum has an im essential conical shape due to the conical shape of the laundry drum Centrifugal centers that direct and effectively drain the wash liquor allow.
  • the passage openings for the wash liquor are advantageously uniform distributed in the wells. This will touch the through openings avoided by the laundry and the textile fibers are protected from damage protected.
  • the suction effect on the openings in washing machines of the prior art acts on the laundry items and significantly to tissue distortion and destruction is effectively prevented.
  • the passage openings are for the Soapy water is limited to areas on the drum jacket that are against the laundry due to additional covers on the inside of the drum casing shielded.
  • Three carriers are particularly preferably provided as covers, both for the circulation of the laundry as well as for the lye creation and discharge are required.
  • the increases on the drum shell are advantageous, which to the Have laundry, designed as essentially flat surfaces. This will ensures that the items of laundry when spinning against them, facing them Optimally create surfaces and avoid tissue distortion.
  • the elevations on the inside of the drum shell are advantageously in Rows arranged side by side distributed around the circumference of the drum shell. She thereby form an interrupted shape of ribs, both in the axial direction and can also run transversely to the axial direction of the laundry drum. This rib structure allows in particular an inexpensive manufacture of the inside of the drum shell.
  • the ridges are on the inside of the drum casing in rows and preferably at right angles running columns arranged around the circumference of the drum shell and form thereby a network or knob structure.
  • the volume of the wells that as Channels are formed, is also enlarged compared to the rib structure, which allows more wash liquor to flow in the channels and still when spinning is removed more quickly from the laundry drum. So for the whole Washing process takes less time.
  • the elevations on the inside of the drum shell rounded edges and rounded corners to those adjacent to the elevations Deepening.
  • the textile fibers are protected particularly efficiently because there are no points of friction on the inside of the drum shell due to the rounded Corners and edges result.
  • the elevations and depressions can be particularly gentle on the laundry Training of the invention may be attached to at least one part, which on the Is attached to the inside of the drum shell.
  • Such parts are advantageously on to arrange the inside of the drum shell through openings and hold the Laundry items effectively away from these openings.
  • the hurled Lye can then on particularly suitable edges of the parts underneath them Parts flow and reach the passage openings there.
  • a laundry drum 1 (Fig. 1) of a drum washing machine according to the invention (not shown) has a cylindrical drum shell in the example shown 3 on the with a plurality of openings 5 for the wash liquor is provided.
  • the wash liquor penetrates through the openings 5 during the Washing process from the tub 11 surrounding the laundry drum 1 (not shown in FIG. 1) into the interior of the laundry drum 1.
  • After washing the wash liquor leaves the drum when pumping out or spinning 1 through the openings 5 in the drum jacket 3.
  • the inside of the The drum jacket has elevations 7 which alternate with depressions 9. In the example shown, the depressions form a net-like knob structure, the elevations 7 being wider than the depressions 9.
  • the depressions 9 form Channels in which the washing liquor flows off when spinning and the washing drum 1 through the passage openings arranged in the channels, for example 5 leaves. Due to the small width of the recesses 9, the laundry items can do not attach to the bottom of the channels when spinning. They therefore form in contrast to the state of the art of draining alkali there is no resistance. In addition, the rounded corners and edges of the elevations 7 Tissue strains and damage to the textile fibers are completely avoided.
  • FIG. 2 shows an enlarged section of area Y from FIG. 1. To see the knob structure formed by elevations 7 and depressions 9 Drum jacket inside 3 of the laundry drum 1. The passage openings 5 are here evenly arranged in the channels formed by the recesses 9.
  • FIG 3 shows a cross section through the knob structure from FIGS. 1 and 2, the through openings 5 can be seen at the deepest points of the depressions 9 are.
  • FIG. 7 Another, particularly advantageous structure is formed by elevations 71 and depressions 9 according to a in Fig. 4 on the left of the line of symmetry 8 in cross section like 3 enlargement of the area Y shown in FIG Items of laundry particularly effectively kept away from the bottom of the recesses 9 because it just stretched across the narrow spaces between the outer edges the elevations 7 can lay.
  • no through openings 5 are provided at the bottom of the depressions, because - as described below - in a different form and elsewhere can be arranged.
  • FIG. 5 represents an alternative embodiment of the laundry drum 1 of the drum washing machine according to the invention (not shown)
  • This laundry drum 1 is designed as a labyrinth drum 1, the one Has drum shell 3, on the inside of elevations 7, which are with depressions 9 alternate, are provided.
  • the passage openings 5 are limited to the areas below the driver 6, and the depressions 9 of the drum casing 3 have no through openings 5 on.
  • the recesses 9 form due to their small width, as already previously described, narrow channels between the flat elevations 7.
