Description

Die Erfindung betrifft einen Laugenbehälter oder eine Wäschetrommel einer Waschmaschine mit einem Mantel und mindestens einer Seitenwand aus dünnwandigen Blechteilen, die teilweise mit die Festigkeit erhöhenden Einprägungen versehen sind, und ferner ein Prägewerkzeug zur Herstellung einer Strukturfläche an der Seitenwand. The invention relates to a tub or a washing drum of a washing machine with a jacket and at least one side wall made of thin-walled sheet metal parts, which are partially provided with strength-increasing embossments , and also an embossing tool for producing a structural surface on the side wall.

Durch die DE 34 28 791 A1 ist ein aus einem dünnwandigen Blech bestehender Laugenbehälter für eine Waschmaschine bekannt, an dessen stimseitigen Wänden zur Erhöhung der Festigkeit Verstelfungssicken eingeformt sind. In dem Bereich zwischen den Versteifungssicken sind die stirnseitigen Wände glatt verlaufend ausgebildet. Derartige glatte Flächen neigen zu Vibrationen, wodurch störende Geräusche entstehen.DE 34 28 791 A1 is a tub made of a thin-walled sheet metal known for a washing machine, on the front walls for Increase in strength stiffening beads are molded. In the area between the stiffening beads, the end walls are smooth. such smooth surfaces tend to vibrate, which creates disturbing noises.

Dies hatte auch schon die DE 196 03 710 A1 erkannt, die den relevanten Stand der Technik für die vorliegende Erfindung bildet. Hier ist allerdings der Mantel des Laugenbehälters allein als der Hauptstörenfried verkannt worden, der mit einer Wölbstruktur versehen worden ist, damit das dünnwandige Blech steifer wird und weniger zu Vibrationen neigt. Eine wesentliche Störquelle im Laugenbehälter und in der Wäschetrommel ist aber nicht gefunden worden.This was already recognized by DE 196 03 710 A1, which shows the relevant status of the Technology for the present invention. However, here is the jacket of the tub only misjudged as the main troublemaker, the one with a vaulted structure has been provided so that the thin-walled sheet is stiffer and less Vibration tends. A major source of interference in the tub and in the laundry drum but was not found.

In einem bekannten Herstellungs-Verfahren zur Wölbstrukturierung dünner Wände und Folien (DE 44 37 986 A1) wird eine Prägeeinrichtung angegeben, mit der einem Blechband fortlaufend eine Wölbstrukturierung dadurch erteilt wird, dass das Blechband mittels einer elastischen Druckrolle gegen eine harte rollende Matritze gepresst wird. Ein solches Verfahren ist aber bei vorgefertigten, im Wesentlichen planen Blechen nicht anwendbar.In a known manufacturing process for vault structuring thin walls and foils (DE 44 37 986 A1) an embossing device is specified with which one Sheet metal strip is continuously given a vault structure by the sheet metal strip pressed against a hard rolling die by means of an elastic pressure roller becomes. Such a process is, however, for prefabricated, essentially flat sheets not applicable.

Der Erfindung liegt die Aufgabe zugrunde, einen Laugenbehälter und/oder eine Wäschetrommel einer Waschmaschine aus dünnwandigen Blechteilen so auszubilden, dass er/sie in sich genügend Steifigkeit aufweist.The invention has for its object to design a tub and / or a washing drum of a washing machine from thin-walled sheet metal parts so that it has sufficient rigidity in itself .

Die Lösung der gestellten Aufgabe gelingt nach der Erfindung dadurch, dass in die Seitenwand zumindest bereichsweise eine flächig ausgebildete Struktur eingeprägt ist und dass die von den zwischen den Vertiefungen der Strukturfläche bestehenden Stegen zwischen einander gegenüberliegenden Begrenzungsseiten der Strukturfläche gebildeten Verbindungsstrecken einen von den sich zwischen gegenüberliegenden Begrenzungsseiten der Strukturfläche erstreckenden kürzesten Geraden abweichenden Verlauf aufweisen. Eine besonders gute Geräuschdämpfung ergibt sich gerade durch derartige Verbindungsstrecken; denn sie vermitteln dem Blechwerkstoff eine für eine gute Geräuschdämpfung günstige Federcharakteristik. The object is achieved according to the invention in that a flat structure is stamped into the side wall, at least in some areas, and in that the connecting sections formed by the webs between the recesses of the structural surface between opposing boundary sides of the structural surface form one of those between opposing boundary sides have the shortest straight line extending the structure surface deviating course. A particularly good noise reduction results precisely from such links; because they give the sheet metal material a spring characteristic that is favorable for good noise damping.

Vorteilhaft ist es, die Struktur wabenförmig zu gestalten, da hierdurch eine besoders hoher Versteifungsgrad erzielt wird.It is advantageous to design the structure in a honeycomb shape, since this makes it particularly odd high degree of stiffening is achieved.

Der Erfindung liegt ferner die weitere Aufgabe zugrunde, ein besonders einfaches Prägewerkzeug für die Herstellung einer Strukturfläche an einem aus dünnwandigem Blech bestenden Geräteteil zu schaffen.The invention is also based on the further object, a particularly simple stamping tool for the production of a structural surface on a thin-walled To create sheet metal best device part.

Die Lösung dieser Aufgabe gelingt bei einer Seitenwand nach der Erfindung dadurch, dass nur an der einen Backe des Prägewerkzeuges eine der zu prägenden Struktur entsprechende Matritze angeordnet ist und die andere Backe im Bereich der Gegenfläche zu der Matritze glatt ausgebildet und mit einem Belag aus elastisch verformbaren Material belegt ist. Da nur an der einen Backe des Prägewerkzeuges eine dem zu prägenden Strukturmuster entsprechende Matritze vorgesehen ist, ergibt sich eine wesentliche Verbilligung des Prägewerkzeuges.This object is achieved in a side wall according to the invention in that a die corresponding to the structure to be embossed is arranged only on one jaw of the embossing tool and the other jaw is smooth in the area of the counter surface to the die and is elastically deformable with a covering Material is occupied. Since a die corresponding to the structural pattern to be embossed is provided only on one jaw of the embossing tool, the embossing tool is substantially cheaper.

Vorteilhafterweise besteht der elastische Belag aus Vukollan®.The elastic covering advantageously consists of Vukollan®.

Bei dem in Fig. 1 dargestellten Laugenbehälter 1 ist in einem sich in radialer Richtung 2 und in Umfangsrichtung 3 jeweils über einen Teil der gesamten Fläche der Seitenwand 4 erstreckenden Bereich in das dünnwandige Material (Blech) der Seitenwand 4 eine flächige, feingliedrige Struktur 5 eingeprägt. Ein solche Struktur 5 kann auch an der anderen Seitenwand des Laugenbehälters 1 vorgesehen werden.In the tub 1 shown in Fig. 1 is in a radial direction 2 and in the circumferential direction 3 each over part of the entire surface of the side wall 4 extending area in the thin-walled material (sheet) of the side wall 4 a flat, delicate structure 5 is impressed. Such a structure 5 can can also be provided on the other side wall of the tub 1.

Bei der in Fig. 2 gezeigten Wäschetrommel 6 ist in das Material der Seitenwände 7 eine wabenförmige Strukturfläche 8 eingeprägt. Die einzelnen Waben dieser Strukturfläche 8 sind dabei so angeordnet und in ihrer Größe so ausgeführt, dass die zwischen den einzelnen, als Vertiefungen eingeprägten Waben bestehenden erhöhten Stege 11 auf ihrer Erstreckung zwischen der radial Inneren und der radial äußeren Begrenzungslinie 9 und 10 der wabenförmigen Strukturfläche 8 einen von den sich ebenfalls zwischen der radial inneren und der radial äußeren Begrenzungslinie 9 und 10 erstreckenden geraden Radiallinien 12 abweichenden Verlauf aufweisen. Dadurch besitzen die durch die Stege 11 zwischen den Begrenzungslinien 9 und 10 gebildeten Verbindungsstrecken eine weiche Federcharakteristik, die eine gute Geräuschdämpfung bewirkt.In the laundry drum 6 shown in FIG. 2, a honeycomb-shaped structural surface 8 is stamped into the material of the side walls 7. The individual honeycombs of this structural surface 8 are arranged and designed in such a size that the raised webs 11 between the individual honeycombs embossed as depressions extend along the radial inner and radial outer boundary lines 9 and 10 of the honeycomb-shaped structural surface 8 have a course which deviates from the straight radial lines 12 which also extend between the radially inner and the radially outer boundary lines 9 and 10. As a result, the connecting sections formed by the webs 11 between the boundary lines 9 and 10 have a soft spring characteristic, which brings about good noise damping.

Die Prägung der Struktur 5 bzw. der Strukturfläche 8 erfogt mittels eines in der Fig. 3 in schematischer Darstellung gezeigten Prägewerkzeuges. Dieses Prägewerkzeug weist zwei Backen 13 und 14 auf. An der einen Backe 13 ist eine der Struktur 5 bzw. der Strukturfläche 8 entsprechende Matritze 15 angebracht. Die andere Backe 14 ist in dem der Matritze 15 gegenüberliegenden Bereich 16 glatt ausgebildet. Auf der glatten Fläche ist ein aus elastisch verformbaren Material (z.B. ein unter dem Markennamen Vulkollan® bekanntes Polyurethan-Elastomer) bestehender Belag 17 aufgebracht. Beim Prägevorgang werden die zu prägenden Seitenwände 4 bzw. 7 zwischen die beiden Backen 13 und 14 des Prägewerkzeuges eingebracht. Beim Zusammenpressen der beiden Backen 13 und 14 wird das Material der Seitenwände 4 bzw. 7 durch die Matritze 15 gegen den Belag 17 gedrückt. Dabei wird an den Stellen, wo die Matritze 15 Erhebungen 18 aufweist, das Material des Belages 17 stärker zusammengedrückt. Im Bereich von Vertiefungen 19 der Matritze 15 drückt dagegen der Belag 17 entsprechende Vertiefungen (z.B. Waben) in das Material der jeweiligen Seitenwand 4 bzw. 7. Durch die Verwendung des elastisch verformbaren Belages 17 erübrigt sich eine gesonderte als Gegenmatritze zu der Matritze 15 geformte Matritze.The structure 5 or the structure surface 8 is embossed by means of an embossing tool shown in a schematic representation in FIG. 3. This stamping tool has two jaws 13 and 14. A die 15 corresponding to structure 5 or structure surface 8 is attached to one jaw 13. The other jaw 14 is smooth in the area 16 opposite the die 15. A covering 17 made of elastically deformable material (for example a polyurethane elastomer known under the brand name Vulkollan®) is applied to the smooth surface. During the stamping process, the side walls 4 and 7 to be stamped are introduced between the two jaws 13 and 14 of the stamping tool. When the two jaws 13 and 14 are pressed together, the material of the side walls 4 and 7 is pressed against the covering 17 by the die 15. At the points where the die 15 has elevations 18, the material of the covering 17 is compressed more. In the area of depressions 19 of the die 15, on the other hand, the covering 17 presses corresponding depressions (for example honeycombs) into the material of the respective side wall 4 or 7. The use of the elastically deformable covering 17 makes a separate die shaped as a counter-die to the die 15 unnecessary ,
