Definitions
- the invention relates to a washing machine with swinging components, especially tubs, to which ballast bodies are attached and ballast bodies therefor.
- EP 0 825 291 A1 discloses a disc-shaped and approximately circular weighting weight attached to the bottom of the tub made of a material mixture, not specified, presumably concrete, with a density> 2 g / cm 3 . It lies on three in a plane parallel to the main level of the floor on contact surfaces and is held by tabs that are spaced apart in a circle perpendicular to the main level and are tensioned from the outside by a folded strap against the narrow wall surface of the weight.
- Suds container attached concrete weight disclosed as weight, in which a metal outer tire is still cast in the weight.
- EP 0 798 412 A2 also discloses a body filled with concrete, which has openings into which a partly frictional, partly positive connection in the manner of a
- Expansion dowels can be used for a screw connection that holds the ballast weight on the washing machine.
- a ballast weight for the front surfaces of washing machine tubs with a washing drum rotating about a horizontal axis which consists of concrete or an agglomerate, in particular a metal-plastic agglomerate and has a curved outer surface at least on the outside, with on of the inside facing the tub surfaces are arranged in such a way that their shape is complementary to the corresponding end face of the tub, so that a stable attachment of the weight is possible.
- EP 0 417460 A2 discloses a washing machine with components for attaching weighting bodies or weighting bodies themselves, which are made from reactive resin concrete (polymer concrete) containing thermosets. It is also mentioned that the weight of the component is due to the inclusion of denser ones
- Aggregates such as B. scrap iron can be increased. This is intended to produce a variable density, that is to say a variable weight, for the various application purposes.
- the production times and costs of such components are also high in mass production, since temperature-dependent pot times and curing times have to be taken into account.
- the invention is based on the problem of a ballast weight as a stiff, break-resistant molded part in the manner of a ring with an easy-to-use one
- thermoplastics To provide attachment to a tub, to easily produce such molded parts separately with a long shelf life and to overcome the disadvantages of thermoplastics known from the prior art.
- the solution initially provides for washing machines with swing-mounted components, in particular tubs, to which ballast bodies, preferably those with material parts made of plastic and iron material, are attached so that the ballast body has approximately a shape like a ring or circular ring section with a selectable cross-sectional thickness and several on at least one circular arc Has recesses and / or openings, the surfaces of which are complementary to corresponding outer contours of Fastening elements are designed on the component.
- the fastening elements on the component and the surface of the ballast body should consist essentially of thermoplastics, which have a honeycomb structure or a closed outer contour with stiffening webs in between in a plane approximately parallel to the surface of the ballast body.
- the ballast body can abut the outer contours of a plurality of the fastening elements at the same time, and the load on the component by the ballast body can thus be minimized.
- the effect is particularly good if the outer contours are oval or kidney-shaped.
- the ballast body can simultaneously on the outer contours of a
- the majority of the fastening elements are in contact, thus minimizing the local stress caused by the ballast body on the component.
- the inventors have found in a large number of studies and calculations using the finite element method that some of the cutouts are always in engagement with the fastening elements, for example an appropriately designed front part of a tub.
- Ballast body selected.
- the further solution provides a ballast body for washing machines, in particular for attachment to suds containers, with material parts made of plastic and iron material, which was produced by injection molding and has a density> 2.4 g / cm 3 ; it consists of a thermoplastic with substantial fillings of hematite and / or magnetite.
- the iron material is then introduced into a mold before injection molding or pressing, preferably a pure ore made of hematite or magnetite or mixtures of the two in the smallest possible granular form, which do not hinder the pressing or injection molding process.
- a pure ore made of hematite or magnetite or mixtures of the two in the smallest possible granular form which do not hinder the pressing or injection molding process.
- very granular metal components can also be used. Tests have shown that mill scale, which in addition to parts of Fe 2 0 3 and Fe 3 0 4 also contains parts of FeO and impurities, could also be used, but the pure ores are preferred.
- thermoplastics have a specific weight or a density of 0.9-1.0 g / cm 3
- hematite and magnetite have a density of about 5.2-5.3 g / cm 3
- metal components are completely enclosed by the thermoplastics, so that after the process a completely homogeneous body with a plastic surface is present.
- the specific weight or the density of> 2.4 g / cm 3 the density of the specific weight or the density of> 2.4 g / cm 3 .
- Hematite fractions or magnetite fractions or mixtures of these have a volume fraction of 35 - 70% in the body, which leads to a specific weight leads, which according to the inventors' experiments should be between 2.5-3.9 g / cm 3 , but preferably 2.9-3.5 g / cm 3 . This is a compromise in the amount of metal component parts to be added because of the good processability z. B. in an extrusion machine with a corresponding shape that is tailored to the dimensions of the ballast body.
- Figure 1 is a synopsis of a model of a tub with a ballast weight model.
- 2 shows the contour of a tub according to Figure 1;
- 3 shows the contour of a ballast weight according to FIG. 1;
- FIG. 4 shows a section of a ballast weight on a fastening element of the tub according to FIG. 1.
- a tub 2 of a front loading washing machine with front loading opening 21 is equipped with a ballast weight 1 around this front opening.
- the weight 1 has different recesses 15. From its top, the weight can be connected to the tub 2 through corresponding openings 13.
- FIG 2 is a perspective view of the tub similar to Figure 1, but with weight 1 removed.
- the outer contours 232, 242 of the fastening elements 23, 24 lie both on the outside of the tub and on the side which is assigned to the front loading opening 21 on a circular line, as a result of which the ballast weight 1 is loaded evenly.
- the principle of the invention is that the recesses or openings on the ballast weight that are complementary to the outer contours lie closely on their surface against the outer contours 232 in order to bring the main part of the load onto the outer contours 232 of the fastening elements. A necessary positive connection of the ballast weight 1 with the tub 2 can then be distributed over a few screw domes 233.
- the rib structure or honeycomb structure of the fastening elements can be clearly seen.
- the calculation of the force vectors has shown that such a structure ensures optimal conditions for the transmission of the occurring moments or loads without having any disadvantages in terms of injection technology.
- the tub is preferably made of plastic such as polyethylene or polypropylene, so that both the tub and the load weight, which is shown in isolation in Figure 3, preferably have the same surfaces.
- FIG. 3 shows the underside or the side of the ballast weight according to FIG. 1 facing the tub.
- the ballast weight has different shapes at its recesses.
- ballast weight has a consideration of the center of gravity of the tub or load weight and a consideration of other components of the Washing machine cutouts 15. To keep the weight in
- the load weight still has elevations 14 within the cutouts, which can engage in the empty spaces of the fastening element 23, 24 and thus selectively increase the ballast weight there.
- FIG. 4 shows a section through the ballast weight according to FIG. 1 on a fastening element 23 with a screw dome 233.
- the weight 1 has an upper recess 12, 13 for the penetration of a fastener into the screw dome 233.
- the weight 1 is once on the surface 22 of the
- Fastening element 24 and the structures 231 give the outer contours 232 a corresponding supporting effect.
- the weight of some fastening elements for corresponding design of the center of gravity still has elevations 14 which engage in the fastening elements 23, but contact them just as little as the screw dome 233 is contacted by the weight.
