- the structures present there are linear. They have elevations, which may extend parallel to the circumferential direction, but may also have different distances from each other.
- the structuring chosen there an advantageous, mechanical laundry treatment with a favorable drainage effect is accompanied. Since the structuring also favors the rigidity of the drum, the use of materials can be kept low. In operation, the drum thus formed was able to convince by a very low-vibration run.
- the structures used in the prior art described above would actually have to be called smaller-scale structures. They point only small elevations of, for example, a height of up to 2.5 mm. These structures are usually tuned to the position of drainage holes in the drum shell so that when spinning parts of the laundry do not get caught with the drainage holes, which could lead to damage of laundry items. The height of the structures is far below the thickness of a Wäscheringes the drum shell, which forms on the drum shell.
- a laundry ring the z. B. When spinning laundry. B. at the end of a washing process, when using a spin speed above a contact speed, arises, essentially - when looking at its cross-sectional shape - form an annular.
- the object of the invention is to get even better results in terms of dewatering in a spin process when spinning laundry or laundry items. In this case, not a further increased spin speed should be sought, but it should be considered the possibilities of a different laundry drum to be trained.
- This object is achieved by a laundry drum according to the independent claim. Preferred embodiments are indicated in the dependent claims and in the following description. Accordingly, the invention relates to a laundry drum for a laundry treating machine having a drum shell having circumferentially distributed structures that rise in the radial direction with respect to an axis of rotation of the laundry drum having a structural height, the jacket spaced a distance R from the drum axis and a wash ring.
- the structures which can be formed in particular in a spin operation of the drum in the laundry treatment machine, has a thickness D. It is provided that the structures have at least cross-sectional profiles which have an at least slight inclination with an inclination angle I with respect to the drum shell at a distance R from the drum axis, the structure height being at least one seventh of the thickness of the forming scrubbing ring.
- a Wäschering As far as in the description of the invention, a Wäschering is mentioned, this is a Wäschering meant with thickness D, which forms at full load or almost at full load according to the operating instructions of the laundry treatment machine at usual laundry.
- the thickness of the scrubbing ring can be determined in test series at rated load in accordance with DIN EN 60456 and at 50% of the maximum final speed, provided that this speed is at least twice as large as an application speed of the drum, in which the laundry in the drum just completely on the drum shell has created.
- a laundry ring at a spin speed above the application speed is formed substantially circular, as formed by the significantly inward, with a dimension corresponding to at least one-seventh of the usually forming Wäscherings trained drum profile a deviating from the ring contour course of a quasi-modified scrubbing, at the end of a spin cycle less residual moisture, in particular 10% less residual moisture at an approximate inclination angle of the structure of 20 °, contains as a conventional substantially circular ring-like laundry ring in laundry drums without structures or exclusively small-scale structures.

- a drum shell with a one-dimensional structure is unwound over its circumferential length of 2T R, then, with a partiality of t1 to 2nR / t1, a structure height and a structure depth are present.
- the cross-sectional profile of the structures for each cutting plane perpendicular to the drum axis A which is infinitesimally spaced from another, is rotated at least an infinitesimal rotation about the drum axis.
- this is a case of a two-dimensional structure. An impression that may arise when looking at the interior of such a drum is that, as if distributed over the circumference, there would be an impression, as would be provided by a helical gear.
- the structures used in the drum according to the invention are coarse-grained compared with the structures of the conventional type. They are in particular, six-part (see Fig. 1). They can also be multi-part in another way. Overall, therefore, the structures are coarse, such as 3 to 30 parts (t1). This forms a roughly textured drum shell.
- the coarse-part structures are four-parted (FIG. 4), seven-parted (FIG. 3) or twelve-parted (FIG. 2).
- the structure elevations are directed substantially inward toward the drum axis A and have a feature height H that is at least 5% and at most 40% of the distance R from the drum axis A.

- a structure or a structural element according to the invention includes an element whose height exceeds at least 5% of the drum radius or 10 mm.
- the inclination angle I shall be based on a minimum value of 5 °. Even if, as stated, an occupancy of the drum shell with 25% of structures or structural elements is sufficient, it is still preferable that a coverage of the drum shell of almost 100% is desired.
- the surface portions formed by depths of the structures at a distance R from the drum axis should be at least 5% of the total area of the drum shell .
- the structures are symmetrically formed with respect to a hypothetical line S running from their highest elevation to the drum axis A.

- a control of a laundry treatment process is executable so that the driver function of a conventional laundry driver is also accepted.
- structures other than this asymmetric structure it will usually be assumed that, in particular three, drivers are to be used.
- DE 10 2006 041 431 A1 teaches that in the presence of structures which are similar to the structures according to the invention, no drivers are to be used.
- the angle of inclination I of the structures, measured against the radius vector can be equal at almost every point of the drum shell, when so-called logarithmic spirals are used to form the structures.
- at least one segment of the structures may all be similar to a logarithmic spiral, that is, within that segment of the structures, the angle of inclination I, measured against the radius vector, is equal to almost every point of the drum shell.

- the first structures taught in the circumferential direction of the drum shell over a circumferential length 2T R are to be supplemented by second structures in the axial direction of the drum shell over a length d, so that a two-dimensionally structured drum shell is present. It has been found that the better the dehumidification, the more surfaces of different orientation on the drum shell, without a significant loss of drum volume.
- the design principle holds that these structures should also be coarse.
- a t1-division and the second structures for a t-2-division are to be defined. As a rule, it can be assumed that every single structure is similar.
- t1 is 3 to 30
- the parting t2 is 3 to 30, preferably 2 to 20.
- irregular structures can be recommended in individual cases. It is possible that regular structures are altered by technical means, such as a random number generator. In this case, it may be preferable for the first structures and the second structures, which have an initially regular structure per se, to be able to be finally formed by a random generator. When automated character or plotting to design such pattern is then interposed at a suitable location of the plotter device of the named random number generator.
- first and second structures are formed in the form of periodic or amorphous patterns.
- the structure elevations are directed substantially inward towards the drum axis and should have a structural height H which is at least 5% and at most 40% of the distance R from the drum axis A, wherein it is necessary to form at least 25% of the drum shell with structures.

With respect to an equal axial length of the drum, this is also a value concerning the volume utilization, which is also present at about 83% with respect to a drum with small-scale structures.
- the cross-sectional profile over the entire axial length of the drum is the same. So it shows a prismatic structure of the drum. However, it is also an oblique offset of these structures, similar to that of helical gears, possible.

- the angle of inclination ⁇ " which results with respect to a concentric to the axial center circular arc line with radius R, is 12 ° to 24 ° , in particular 17 ° ..
- the cross-sectional area formed according to Fig. 4 is about 77% to 81%, in particular about 79% usable, whereby the reference value 100% is formed by a drum with small-scale structures, compare the circular arc line 3 with radius R, which in the present case connects the deep regions of the coarse-part structures according to the invention. 4 with about 79% in relation to a drum with small-scale structures.
- the structure curves can be easily realized by arcs or straight lines. If so-called logarithmic spirals are used, then the angle of inclination - measured against the radius vector at each point of the drum shell - has the same value.
- the drainage holes are successfully attached. It may also be expedient to supplement the structures created by the invention with conventional, smaller-scale structures (not shown) while providing additional drainage holes.
- FIG. 5 shows, in a schematic cross-sectional view, a structured drum casing 2 according to the invention with an indication of a modified laundry ring 4 occurring in the invention.
- the structure height H should amount to at least one seventh, but usually to approximately at least half the thickness D of the usually forming wash ring, without deviations in the graphic representation of FIG. 5 could have a meaning.
- it is a modified Wäschering 4, which forms after spinning with a spin speed above the application speed, wherein a laundry ring with the thickness D is meant that at full load or almost at full load according to the operating instructions of the laundry treatment machine in per se usual Laundry is training.
- FIG. 6 a schematized cross-sectional view with respect to the outer drum shell 3 with an unchanged circular cross section.
- the structure shown in FIG. 1 can be used as a basis.
- the individual structures 1, preferably with the segments 1 a and 1 b, which can be created from a material other than the material of the drum shell 3, are introduced on the inside of a drum shell 3 originally present and releasably detachable with the drum shell 3, as by a Clamping, or permanently, for example by welding or gluing, connected.
- the circular ring-like cross section of the original drum shell 3 is therefore retained.
- the distance of the shell 3 to the axle center also corresponds to the above-explained radius R, ie half of the diameter of the drum T.
- the material of the drum shell 3 may be stainless steel, while the material of the individual structures 1 or segments, such as 1 a, 1 b, a, for example thermoplastic, plastic can be.
- the effective drum structure 2 with the structure course 2a and 2b, which is determined, for example, via segments 1a and 1b, is achieved by the individual structures 1 or segments 1a and 1b projecting inwardly relative to the outer drum shell 3 to the center axis A.
- an inclination angle I of the structure profile is formed, which is shown for example.
- the height H of the structure 1 is given by reference from a distance from the drum shell 3 to its tips projecting furthest inward toward the axis center.
- measured values of the residual moisture are represented as percentage values along the ordinate as a function of the angle of inclination of a structure 1 of the in particular structured drum shell 2 with a specific inclination angle I in degrees (°) along the abscissa. It takes into account the usual definition of the residual moisture, which results as a quotient of the amount of water bound in the laundry after spinning in relation to the dry weight of the laundry.
- the mean values of the residual moisture are recognizable by block diagrams, which are connected with connecting lines. In addition, a fitted logistic function is shown, cf. the arcuate course.
- a particularly strong increase in the dehumidifying effect (reciprocal of which is the residual moisture shown in the diagram along the ordinate) is given at an angle of inclination of 10 ° to 20 ° .
- At an angle of 20 ° there is a good spinning effect without the percentage of useful drum volume falling too much towards lesser values relative to a conventional circular drum cross-section of 100%.
- Fig. 8 a) is a cross-sectional view taken on the section line a -a of the unwound, structured drum shell 2. Even if only a one-dimensional structure, as laid down in advance (see also Fig. 1), would be present, such a representation would result. However, it can be seen in comparison with FIG. 8 b) that the representation of FIG. 8 a) would result for each subregion corresponding to the subdivision t 2 along the axial direction according to vector V 2. The underlying section line a-a could also be in another row of the representation of FIG. 8 b). Fig. 8 a) thus also shows, as already shown in advance, that a structure 1, with the segments 1 a and 1 b is present.
- the structure can be constructed symmetrically to a symmetry line S.
- the structure has a height H.
- the structures 1 extend over the unwinding length 2T R of the drum shell, where R is the radius of the drum shell 3 in the unstructured state.
- Figure 8b shows in plan view how an exemplary two-dimensional structure results.
- a dimension d of the drum in the axial direction 4 structures 10 are evenly distributed.
- one of the structures 10 in the direction of the vector V2 is shown by way of example in a sectional illustration corresponding to the section line c-c.
- the picked-out structure 10 has segments 10a and 10b. There may be a symmetrical structure symmetrical to a symmetry line S '.
- the structure 10 is with respect to Structure 1 adapted in height H, The upper plateau (without reference numeral) of the structures 1, 10 thus has no discontinuity.
- the structures do not have an upper plateau, but are almost pyramid-shaped.
- a hexagonal pyramid can also be chosen.
- the structures themselves can be constructed very differently.
- known basics about crystal classes of the plane can be used. Deviating from this, non-periodic patterns or amorphous patterns can also be formed. Random distributions or distributions that deliberately deviate at least partially from symmetrical distributions are sought. As an example, a table tennis ball bed (not shown) is given.
- the patterns can also be modified according to random criteria. It could also be a random generator for drawing or plotting used to design such patterns. However, it is important that a good drainage effect when used in a drum T according to the invention is achieved by a pattern obtained by the example given bases and technical means as the basis of a two-dimensional structure with two vectors, with a knowledge of fundamentally obtained in the sense of the invention the expert to arrive at a suitable solution with very few experiments.
