Definitions
- the invention relates to a drum for a washing treatment machine, the
- Drum is rotatably mounted within the housing of the washing treatment machine and has at least one base plate and a jacket, each of which at least partially consist of sheet metal and individually or both are provided with a domed structure directed towards the inside of the drum.
- a drum is known from WO 98/20195.
- the arch structure is formed from a plurality of hexagons arranged at least almost directly next to one another; it is therefore generally referred to as a honeycomb drum.
- the edge areas of the hexagons take in the flood holes at their corner points, which according to WO 98/20195 are said to be only 2 mm in diameter and no longer have to have any tulips in order to protect the laundry even during the spin cycle. Accordingly, the edge areas must be 1.5 to 2.5 times the hole diameter between 3 and 5 mm wide.
- the invention has for its object to provide a drum of the type mentioned, in which the vaulted structure has directly adjacent elements, but the flood holes can still be left enough space so that they still have sufficiently large diameters for sufficient lye drainage. Furthermore, the production of the arch structure should not be problematic either in itself or in its effect on other specifications. The improved stiffness that can be achieved by the arch structure should at least be maintained or better to be increased. According to the invention, this object is achieved in that the arch structure consists of knobs directed towards the inside of the drum, the edges of which are essentially circular or elliptical or oval. In this way, curved elevations similar to spherical domes can be designed which just touch on their peripheries with the respective adjacent elevation. The laundry is thus prevented from penetrating to the bottom of the edge areas. Thermoforming processes in the manufacture of
- the arch structure is uniform and the material remains homogeneous. Those edge areas that form more extensive, polygons-like areas due to the curves of the elevations automatically leave more space for larger flood holes. This results in a considerably simpler manufacture of these arch structures compared to those from the prior art, because no such tight tolerances have to be observed when centering the arch structure to be introduced with respect to the perforation that has already been produced.
- the knobs are arranged at the intersections of a regularly polygonal axis pattern.
- the regular arrangement of the knobs also has the advantage that the arrangement of the axis pattern matches the arrangement of the hole pattern, which enormously simplifies production.
- a particularly advantageous form of embodiment of the invention is obtained if the axis pattern on the lateral surface contains a multiplicity of adjacent, equilateral triangles.
- the least possible polygonal, here triangular, area of the edge areas between the non-adjacent knobs is simplified.
- a further development of the invention is suitable for the universal use of the structure according to the invention, in which the alignment lines of the axis pattern follow the shape of the outer edge of the jacket or of the bottom, ie. H. for example, that they are straight or circular.
- This structure can then be used in the best way for disc-shaped bottoms of laundry drums, without forming large areas without knobs.
- a further development of the invention is particularly suitable, in which flood holes for the passage of the wash liquor are arranged on the lateral surface between the knobs at the intersection of the bisectors of the triangles.
- the arrangement of flood holes in this area has a particular advantage because the moisture driven into the area of the drum casing during the spin cycle, as soon as it has reached the inner surface of the drum casing, continues from the areas where the knobs touch to the
- Crossing points is driven because the valleys between the knobs widen towards the crossing points; So the moisture cannot remain at the narrowest points, but is driven from there to the other areas at the location of the crossing points.
- Knobs are attached at the intersection of the bisectors in at least approximately circular areas, the periphery of which forms sections of the circumference of the knobs in a circle.
- the selected structure increases the rigidity of the lateral surface. If the flat perforation at the aforementioned points of intersection should nevertheless prove to be too dangerous for the laundry, according to a further particularly advantageous development of the invention, there is best enough space here for the flood holes in the plane furthest away from the drum axis a bulge placed outside the drum.
- the areas at the crossing points are large enough to accommodate a protuberance through which the
- the minimum distance between the knobs should be about one eighth to one twenty fifth in relation to their diameter. A value of around a tenth has proven to be very suitable.
- the height of the knobs in relation to their diameters should be about one fifth to one twentieth. A value of around a twelfth has proven to be very suitable.
- the further development of the invention is particularly advantageous in such a way that the alignment lines are arranged concentrically to the center of the bottom disk and the axis patterns arranged on the alignment lines correspond to the shortening of the center of the drum
- knobs Have a shortened side line around the circumference of the respective escape line.
- a homogeneous structure of knobs can thus be arranged on the base plate, which in turn is advantageous for the congruence of the knob structure and the hole pattern.
- the diameter of the knobs and / or the distances between them are reduced in accordance with the shortening of the circumference of the assigned escape line.
- the structure of the base plate has the advantage of congruence between the knob structure and the hole pattern that the large number of differently sized elements on the base plate form just as many individual resonators for different listening frequencies, which broaden the resonance spectrum very much, but in return extremely dampen its resonance amplitudes.
- the surface of the drivers can also be provided with a domed structure made of knobs. This can be advantageous for the mechanical processing of the laundry in the washing program section.
- FIG. 1 is a perspective view of a laundry drum, which is provided on its drum shell and on a base plate with knob structures according to the invention
- FIG. 2 shows a detail from a development of a drum casing equipped with a shape of the knob structure according to the invention with pleading flood holes
- 3 shows an enlarged cross section of a knob curvature along a section line HI-HI in FIG. 2
- FIG. 4 shows a detail from a development of a drum casing with a different shape of the knob structure according to the invention than the shape shown in FIG. 3, with tulip-shaped flood holes, FIG.
- Fig. 5 is an enlarged cross section of a knob curvature along a section line V-V in Fig. 4 and
- FIG. 6 shows a detail of the view of a base plate which is provided with a knob structure according to the invention.
- the laundry drum 1 shown in FIG. 1 can be rotated about an at least approximately horizontally oriented 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 rotating end plate or be mounted on a standing end plate (both not shown).
- the drum is firmly connected to a base plate 3, into which drive torques can be introduced.
- the base plate has a star-shaped embossing 4, which is only partially visible here and serves the stability of the plate. It can also be reinforced on the back with a cast star, not shown.
- the drum 1 is formed by the jacket 5, which consists of a cylindrically bent sheet metal strip held together at a point not visible here with a connecting seam.
- the base plate 3 and the development of the drum shell 5 have been provided with a knob structure in an embossing tool, which is shown and described below. While the knobs 6 in the drum casing 5 are all of the same size, the base plate 3 also has the largest knobs 8 on its largest escape line circle and knobs 9 to 15 on each of the smaller escape line circles towards the center, each with gradually smaller diameters. As a result, the knobs 6 on the drum casing 5 and the knobs 8 to 15 on the base plate 3 can each be arranged in a triangular arrangement with respect to one another, as will be explained in more detail below.
- knobs 6, which consist of an embossment drawn in the manner of a spherical cap (see FIG. 3), on the intersections of a regularly polygonal axis pattern, namely a triangular axis pattern, are arranged.
- This axis pattern is defined by the alignment line 16 and the other two axes 17 and 18 determined, of which the escape line 16 is parallel to the outer edge 19 of the drum jacket sheet metal strip.
- the two axes 17 and 18 are each rotated by 60 ° to the left or by 60 ° to the right to the escape line 16. Accordingly, all axes have duplicates arranged parallel to one another, all of which have the same distance from one another.
- the distance A between the knobs 6 is about one eighth to one twenty fifth, preferably one tenth, of theirs
- the diameter D of the flood holes is of course also spun, which in the example shown can be approximately 3.5 mm. This value also stands for good fluid drainage, which is supported by the good drainage between the knobs 6.
- FIGS. 4 and 5 for the design of the cladding sheet 5 is the same as the example according to FIGS. 2 and 3 with regard to the knob structure and the arrangement of the flood holes.
- the flood holes 25 are arranged in the triangular areas 24 between the knobs 6 in a floor plane 26 (FIG. 5) of depressions 27 drawn outward like tulips. This makes it difficult for the items of laundry lying between the knobs 6 during the spin to penetrate into the depressions 27 to such an extent that the flood holes 25 can only be reached at all; let alone that the laundry see it could also penetrate so as to reach the dangerous ridge on the outer edge of holes 25.
- FIG. 6 shows a section of the sheet metal of a base plate 3 (FIG. 1).
- the outer edge 28 of the base plate 3 is also the outer boundary of the surface on which the knob structure can be attached.
- the inner boundary of this area is defined by line 29.
- the basic structure of the knob arrangement and the hole pattern corresponds to that in FIGS. 2 and 4.
- the alignment line 30-1 and all of its inner parallels 30-2, 30-3 etc. are concentrically circular in accordance with the axis 16 in FIG. 2 in a position parallel to the outer edge 28.
- the other axes 31 and 32 - rotated 60 ° to the right and to the left against the alignment line 30-1 - are curved toward the center of the circle, so that the side lines of the triangles formed from them shorten with increasing proximity to the center of the circle, which lies on a distant crossing point M of the two radius lines R drawn.
- the side line F-K of the triangle F, K, L lying further inside is shorter than the side line E-F of the triangle E, F, G lying further outside.
- the diameters of the knobs 6 are smaller with increasing proximity to the center of the circle M, because the inner alignment line 30-2 is shorter than the outer one (30-1) and therefore for the same number of
- Noppen 6 only less distance is available. This also explains the shortening of the side lines of the triangles and the curvature of the axes 31 and 32.
- drivers for lifting the laundry during the rotation of the drum are arranged, the surfaces of these drivers facing inside the drum can also be designed with a corresponding knob structure. This can be somewhat advantageous for the mechanical processing of the laundry.
- the invention is not restricted to the axis patterns shown here. Further regular axis patterns are conceivable for solving the same task. So can For example, a rectangular or, specifically, square arrangement of the axes can be quite advantageous. Then there might be additional flood holes in the square areas between the knobs or a mixture of flat and bulging flood holes. Mixed forms of differently regular axis patterns can also be used. Furthermore, this type of arch structure can also be used in laundry drums for tumble dryers.
