Definitions

  • the invention relates to a drum for a laundry treatment machine, wherein the drum is rotatably mounted within the housing of the laundry treatment machine and has at least one bottom plate and a jacket, each consisting at least partially of sheet metal and individually or both with a directed towards the drum interior arch structure out to the drum interior directed nubs, which are arranged in the intersections of a regular triangular axis pattern, being arranged on the lateral surface between the nubs at the intersection of the median line of the triangles flood holes for the passage of the wash liquor.
  • Such a drum is out of the WO 98/20195 known.
  • the arch structure is formed as from a plurality of at least almost immediately adjacent hexagons arranged; it is therefore commonly referred to as a honeycomb drum.
  • the marginal areas of the hexagons take up at their vertices the flood holes, according to WO 98/20195 should be only 2 mm in diameter and have no tulip more to protect the laundry even during the spin cycle. Accordingly, the edge areas of 1.5 to 2.5 times the hole diameter must be between 3 and 5 mm wide.
  • drum embodiments with a knobbed structure are made JP-A-08 182 887 .
  • the invention has for its object to provide a drum of the type mentioned, in which the vault structure has directly adjacent elements, the flood holes but still enough space can be left so that they still have enough large diameter for a sufficient liquor removal. Furthermore, the production of the vault structure should be problematic neither in itself nor in their effect on other specifications. The improved rigidity achievable by the arch structure should at least be maintained or better yet increased.
  • edges of the studs are formed substantially circular or elliptical or oval, and the flood holes are mounted between the knobs at the crossing of the sorenzierenden in at least approximately circular-shaped areas, the periphery of the sections of the circumference Form pimples in a circle.
  • the nubs are arranged in the intersections of a regular triangular axis pattern.
  • the regular arrangement of the knobs has over the aesthetic value also has the advantage that the arrangement of the axis pattern matches the arrangement of the hole pattern, which greatly simplifies the production.
  • flood holes for the passage of the wash liquor are arranged on the lateral surface between the knobs at the crossing point of the side bisectors of the triangles.
  • the arrangement of flood holes in this area therefore has a particular advantage, because the moisture driven into the area of the drum shell during spinning, once it has arrived on the inner surface of the drum shell, from the areas where the nubs touch, further to the Crossing points is driven, because the valleys between the pimples extend to the crossing points; The moisture can not remain at the narrowest points, but is driven from there to the other areas at the point of intersection.
  • the flood holes between the dimples at the crossing point of the side bisectors are arranged in at least approximately circular shaped areas, the periphery of which forms part of the circumference of the dimples in a circle.
  • the selected structure increases the rigidity of the lateral surface.
  • a particularly advantageous form of embodiment of the invention results when the axis pattern on the lateral surface contains a plurality of adjacent, equilateral triangles. Namely, on the one hand, the simplified production with a least possible polygonal, namely triangular, area of the edge areas between the non-contiguous knobs to unite.
  • a refinement of the invention is suitable in which the alignment lines of the axis pattern follow the shape of the outer edge of the jacket or of the floor, ie. for example, they are straight or circular. This structure can then be used well even with disc-shaped bottoms of laundry drums, without forming too large areas without nubs.
  • the minimum spacing of the dimples should be approximately one-eighth to one twenty-fifth in relation to their diameter. A value of about one-tenth has proved to be very suitable.
  • the height of the nubs in relation to their diameters should be about one fifth to one twentieth. A value of about one twelfth has proved to be very well suited.
  • the alignment lines are arranged concentrically to the center of the bottom disc and arranged on the alignment lines axis pattern shortened to the drum center according to the shortening of the circumference of the respective alignment line Have sideline.
  • a homogeneous structure of nubs can be arranged on the bottom disk, which in turn is for the congruence of the nub structure and the hole pattern of advantage.
  • the diameter of the knobs and / or the distances between them are reduced according to the shortening of the circumference of the associated alignment line.
  • the structure of the bottom plate on the advantage of congruence between nub structure and hole pattern also has the advantage that form the plurality of different sized elements on the bottom disc exactly as many individual resonators for different audible frequencies, which indeed greatly widen the resonance spectrum, but its resonance amplitudes extremely dampen.
  • the surface of the drivers can likewise be provided with a convex structure of nubs. This can be advantageous for the mechanical processing of the laundry in the wash program section.
  • washing drum 1 can be rotated about an at least approximately horizontally aligned axis 2. For this purpose, it is connected to a drive, not shown here.
  • the front of the drum 1 is open. It can either be closed with a co-rotating forehead bottom or be mounted on a standing forehead bottom (both not shown).
  • At the back of the drum with a bottom plate 3 is firmly connected, in the drive torque can be introduced.
  • the bottom disc has a star-shaped stamping 4, which is only partially visible here and serves the stability of the disc. You can also be reinforced on its back with a cast star, not shown.
  • the drum 1 is formed by the jacket 5, which consists of a cylindrically curved and held together at a point not visible here with a connecting seam metal strip.
  • the bottom disk 3 and the unwinding of the drum shell 5 have been provided with a nub structure prior to connection to each other in an embossing tool, which is shown and described below. While the nubs 6 in the drum shell 5 are all the same size, the bottom plate 3 has on its largest alignment circle and the largest nubs 8 on all smaller alignment lines further to the center nubs 9 to 15, each with gradually smaller diameters. As a result, the knobs 6 on the drum shell 5 and the knobs 8 to 15 on the bottom plate 3 in each case in a triangular arrangement attach to each other, as will be explained below in detail.
  • the nubs 6, which consist of a kugelkalottenartig drum inward drawn imprint are arranged on the intersections of a regular polygonal axis pattern, namely a triangular axis pattern.
  • This axis pattern is by the alignment line 16 and the other two axes 17th and 18 determines, of which the alignment line 16 is parallel to the outer edge 19 of the drum shell sheet metal strip.
  • the two axes 17 and 18 are each rotated by 60 ° to the left or 60 ° to the right to the alignment line 16. All axes have mutually parallel duplicates, all of which have the same distance.
  • a plurality of equilateral triangles is formed, one of which (20) is shaded here, whose corners E, F and G are at the same time the points of intersection of the axes 16, 17 and 18 and 18-2.
  • the bisectors 21 of these triangles intersect at the center of gravity of the triangles, which is at the same time the point of intersection 22 and the location on which a respective flood hole 23 is arranged.
  • the diameter D of the flood holes which may be about 3.5 mm in the example shown, is also suitable for the determination of the optimum with regard to the laundry protection during spinning. This value also stands for a good liquid removal, which is supported by the good drainage between the nubs 6.
  • FIG. 6 non-inventive example of a nub structure shown shows a section of the sheet of a bottom plate 3 ( Fig.1 ).
  • the outer edge 28 of the bottom plate 3 is at the same time the outer boundary of that surface on which the nub structure is attachable.
  • the inner boundary of this area is determined by the line 29.
  • the basic structure of the knob arrangement and the hole pattern corresponds to that in the Figures 2 and 4 , However, here are the line of flight 30-1 and all their internal parallels 30-2, 30-3, etc. according to the axis 16 in Fig. 2 in a parallel position to the outer edge 28 concentric circular.
  • the other axes 31 and 32 - rotated to the right and to the left in each case by 60 ° against the alignment line 30-1 - curved towards the center of the circle, so that shorten the side lines of the triangles formed from them with increasing proximity to the center of the circle, lying on a remote crossing point M of the two radius lines R drawn.
  • the other side lines which are comparable in each case.
  • the diameter of the nubs 6 with increasing proximity to the center of circle M are smaller because the respective inner alignment line 30-2 is shorter than the respective outer (30-1) and thus for the same number of nubs 6 only less distance is available , This explains the described shortening of the side lines of the triangles and the curvature of the axes 31 and 32.
  • driver for lifting the laundry during the drum rotation can also in Drum interior facing surfaces of this driver may be formed with a corresponding knob structure. This may be advantageous for the mechanical treatment of the laundry in some way.
  • This type of vault structure is also applicable to laundry drums for dryers.
