Definitions

  • One aspect of the invention relates to a method for producing a casing wall for a laundry drum for a household appliance for the care of laundry items. Another aspect of the invention relates to a casing wall for a laundry drum. Another aspect of the invention relates to a laundry drum for a household appliance for the care of laundry items. Yet another aspect of the invention relates to a household appliance for the care of laundry items with a laundry drum.
  • Household appliances for washing laundry such as a washing machine or a washer-dryer, have a laundry drum. This usually has a hollow cylindrical shell wall.
  • a laundry drum usually also has a base plate at the back. This means that the casing wall in the hollow cylinder shape is closed at the back.
  • the laundry drum usually has what is known as a front base.
  • the front base and the base plate are usually separate parts from the casing wall that are connected to the casing wall. In this context, it is known that folded connections are created between the components mentioned.
  • the jacket wall has bulges oriented radially outwards.
  • EP 1 872 881 A2 A drum shell is known in which an embossed structure with a large number of individual embossed elements is created. However, the embossed elements there are designed to be spaced apart from one another, so that the number of embossed elements is limited. There, the already cylindrically bent drum shell is held in a fixed position during the embossing process.
  • such a shell wall has a radially expanded area. This is located radially further outward than an end edge strip of the drum shell than this edge strip. This is known, for example, from WO 2011/064201 A1 known. A large number of holes are formed in the radially expanded area of the drum shell.
  • the KR 10 2020 0105071 A a laundry drum with a drum shell is known. Larger, radially outward-facing embossed areas are formed in the drum shell. A large number of holes are formed in each of these embossed areas.
  • IT MC20 090 241 A1 which shows a manufacturing process for a laundry drum from the prior art, from which the present invention is based.
  • the compensation embossing can also be counteracted in a very targeted manner.
  • the compensation embossing can also be counteracted in a very targeted manner.
  • the compensation embossing it is therefore possible for the compensation embossing to be produced directly in the edge strip itself. This can therefore lie completely within the edge strip.
  • at least one such compensation embossing it is also possible for at least one such compensation embossing to be formed adjacent to the edge strip.
  • This is in a conical section of the expansion region. In a cross-sectional view, the expansion region has this conical region or conical section. This borders directly on the edge strip and represents the radial bulge starting from the edge strip. An essentially axial section of the expansion region is then formed adjacent to this conical section. In cross-section, this region therefore runs essentially parallel to the longitudinal axis of the hollow cylinder.
  • the compensation embossing is only formed in sections in the circumferential direction around the longitudinal axis of the hollow cylinder. The compensation embossing is therefore not formed completely closed all the way around.
  • the embossed structure is created as a coherent, embossed zone only partially encircling the longitudinal axis of the hollow cylinder.
  • an azimuth zone is formed adjacent to this embossed zone.
  • the azimuth zone is different from the embossed zone.
  • this relates to the azimuthal width.
  • this can also affect the functionality of the two zones.
  • the azimuth zone is intended to position or form a driver of the laundry drum on it.
  • the embossed zone is not intended to have a driver arranged or formed on it.
  • the at least one compensation embossing is generated at least in part at the azimuth point at which the azimuth zone is formed, viewed in the direction of rotation around the longitudinal axis of the hollow cylinder. Due to the fact that the embossed structure, in particular in its close-meshed design, is not formed completely around the longitudinal axis in one embodiment, but rather the at least one azimuth zone is also formed in this regard, locally different axial heights of the edge strip can arise precisely due to this situation. In particular, in the area of the azimuth zone, an axially different height of the edge strip can occur than in the area in which the embossed structure is generated in the expansion area.
  • the at least one compensation embossing is generated there.
  • the at least one compensation embossing is generated over its entire azimuthal length completely within the azimuthal width of the azimuthal zone.
  • At least one driver of the laundry drum is formed in the azimuth zone of the expansion region.
  • the driver is a separate component to the casing wall.
  • a fastening structure for this separate driver can be formed in the azimuth zone.
  • This fastening structure can, for example, have fastening holes in the azimuth zone. The driver can then be fastened to these.
  • the expansion region has been created, at least several, in particular at least three, centering receptacles are created in the expansion region.
  • the centering receptacles are designed to set a reference position of the hollow cylinder in a horizontal plane at least for the subsequent creation of the embossed structure.
  • the hollow cylinder can then be aligned or brought into this horizontal reference position by engaging elements in the centering receptacles before the embossed structure is created. This enables the embossed structure to be created particularly advantageously and with horizontal accuracy. It can thus be created in a particularly advantageous manner with corresponding horizontal accuracy in the direction of rotation around the longitudinal axis.
  • the edge strip is locally prestressed azimuthally to the final diameter in an azimuth section.
  • this prestressing only takes place locally in an azimuth section.
  • the final azimuthal length can then be easily achieved using this procedure. In particular, this can then be achieved with regard to the circular shape of the edge strip around the longitudinal axis at the same time as the embossed structure is created.
  • the azimuthal prestressing of this azimuth section and the generation of the embossed structure in the expansion region are carried out at least temporarily simultaneously.
  • a first embossed structure is produced as a continuous, embossed zone only partially encircling the longitudinal axis of the hollow cylinder.
  • a continuous, embossed zone is produced only partially encircling the longitudinal axis, this being produced as a second embossed structure.
  • the second embossed structure is produced separately and spatially separated from the first embossed structure.
  • a third embossed structure is produced as a continuous, embossed zone only partially encircling the longitudinal axis.
  • this third embossed structure is separate from the first and second embossed structures. In this respect, it is also produced spatially spaced from the other two embossed structures.
  • the three embossed zones are created simultaneously. This ensures that no distortion of the shell wall occurs when such a radial force is applied to the expansion area. This achieves the particularly advantageous maintenance of the symmetrical shape of the shell wall and in particular of the expansion area.
  • the relevant molding tools or molding jaws of the production system are arranged equidistant from one another in the direction of rotation around the longitudinal axis.
  • the edge strip 8 is here, or at this point in time when the entire washing drum was manufactured, still formed as a single layer.
  • the edge strip 9 is here still formed as a single layer.
  • this casing wall 1 has fastening receptacles 16. These fastening receptacles 16 are intended for fastening a driver. In particular if this is designed as a separate component.
  • the casing wall 1 also has at least one compensation embossing 18.
  • a compensation embossing is a separate, embossed compensation element. It is formed at a distance from the embossed structures 13, 14 and thus from the embossed elements 15.
  • the compensation embossing 18 is formed in the edge strip 8. In another embodiment, it can also be formed in the edge strip 9 in addition to or instead of this. In one embodiment, at least one compensation embossing 18 is formed completely in the edge strip 8.
  • the compensation embossing 18 is intended for the local adjustment of the height h of the edge strip 8 measured in the axial direction and thus in the direction of the longitudinal axis A. This height h is measured between the first edge 6 and the first hollow cylinder edge 4.
  • the compensation embossing 18 is intended and designed to adjust or compensate for this height h.
  • the height h in the circumferential direction around the longitudinal axis A for the entire edge strip 8 can be formed in such a way that there is a maximum deviation of +/- 0.3 mm.
  • the at least one compensation embossing 18 is formed in the circumferential direction around the longitudinal axis A and thus, viewed azimuthally, at the azimuthal point at which the azimuthal zone 20 also extends.
  • the at least one compensation embossing 18 is formed in its azimuthal length completely within the azimuthal length of this azimuthal zone 20.
  • it can be provided that the compensation embossing 18 is formed in the cone section 10. This can be completely or at least partially the case.
  • such a laundry drum can have a front base. This is separate from the casing wall 1.
  • the front base can be connected to the casing wall 1 by a flanging process or a folding process.
  • the edge strip 8 is connected to this front base by a folding connection. This is a direct connection in each case.
  • Fig.2 the casing wall 1 is shown in a side view.
  • the embossed structure 14 is not shown here.
  • the connection point 19 is shown, at which the abutting edges of the base plate of the casing wall 1, which is shaped as a hollow cylinder, are connected to one another, in particular welded to one another. This is formed here in the azimuth zone 20.
  • a base plate of the casing wall 1 is first provided. This plate part is in particular unrolled from an endless roll and cut to length accordingly.
  • This plate is then rolled up to form a hollow cylinder 2 and connected to one another at the end edges facing each other. In particular, a welded connection is created here.
  • the hollow cylinder 2 thus prepared is then radially expanded in certain areas in a production plant.
  • corresponding expansion elements of the production plant can be introduced into the finished hollow cylinder 2 or the hollow cylinder 2 is set up accordingly so that it surrounds these expansion elements.
  • the expansion elements or mold jaws are then moved radially so that the radially bulged expansion area 3 is formed in the hollow cylinder 2.
  • the centering receptacles 17 already explained are then preferably formed.
  • the casing wall 1 As it has been manufactured up to that point, is axially raised and brought into a reference position. It no longer rests with an edge on edge seats of the production system, but is raised in this respect.
  • corresponding elements can engage in the centering seat 17 and this desired reference position, which is an exact horizontal alignment of the hollow cylinder manufactured in this way, is then set.
  • the edge strip 8 is then preferably pre-stressed in a further, subsequent production step. and/or the edge strip 9. In particular, an azimuthal stretching of this edge strip 9 and/or 8 is carried out.
