Waschtrommel für eine WaschmaschineWashing drum for a washing machine

Die Neuerung betrifft eine Waschtrommel für eine Waschmaschine, deren zylindrischer Mantel mit einer Vielzahl von Durchflutungslöcher zum Durchtritt der Arbeitsflüssigkeit versehen ist.The innovation concerns a washing drum for a washing machine, the cylindrical casing of which is provided with a large number of flow holes for the passage of the working fluid.

Wäschetrommeln der in Rede stehenden Art bestehen aus einem zylindrischen Mantel, der in üblicher Weise mit einer Vielzahl von Durchflutungslöchern versehen ist, durch die hindurch die Arbeitsflüssigkeit beim Waschvorgang aus dem Laugenbehälter in den Waschtrommel-Innenraum eindringen kann und durch die beim Schleudervorgang die Arbeitsflüssigkeit dann wieder austritt.Washing drums of the type in question consist of a cylindrical casing which is usually provided with a large number of flow holes through which the working fluid can penetrate from the tub into the washing drum interior during the washing process and through which the working fluid then exits again during the spinning process.

Ausgehend von diesem Stand der Technik liegt der Neuerung die Aufgabe zugrunde, mit einfachen Maßnahmen eine Verbesserung der Zuführung der Arbeitsflüssigkeit zu den Durchflutungslöchern im Waschtrommelmantel zu erreichen.Based on this state of the art, the innovation is based on the task of improving the supply of the working fluid to the flow holes in the washing drum shell using simple measures.

Die Lösung dieser Aufgabe gemäß der Neuerung besteht darin, daß der Trommelmantel wabenartig ausgebildet ist und die Durchflutungslöcher Teil der Waben sind. In Weiterbildung der Neuerung sind die Waben als Prägungen in Sechskantform ausgebildet.The solution to this problem according to the innovation is that the drum shell is designed like a honeycomb and the flow holes are part of the honeycomb. In a further development of the innovation, the honeycombs are designed as embossings in a hexagonal shape.

Die mit der Neuerung erzielbaren Vorteile sind u. a. darin zu sehen, daß die Arbeitsflüssigkeit zügig zu den Durchflutungslöchern und beim Schleudern ebenso rasch durch diese abgeleitet wird.The advantages that can be achieved with the innovation include the fact that the working fluid is quickly directed to the flow holes and is drained through them just as quickly during spinning.

Ein Ausführungsbeispiel der Neuerung ist in der Zeichnung dargestellt und wird anhand dieser nachfolgend näher beschrieben.An example of the innovation is shown in the drawing and is described in more detail below.

Fig. 1 eine Waschtrommel,Fig. 1 a washing drum,

Fig. 2 einen vergrößerten Ausschnitt aus dieser Waschtrommel in Draufsicht,Fig. 2 an enlarged section of this washing drum in plan view,

Fig. 3 einen Schnitt gemäß Fig. 2.Fig. 3 shows a section according to Fig. 2.

Die Waschtrommel 1, die im Laugenbehälter einer Waschmaschine drehbar gelagert ist, hat. einen zylindrischen Mantel 2, der in üblicher Weise mit einer Vielzahl von Durchflutungslöchern 3 (Perforationen) versehen ist. Durch diese Durchflutungslöcher hindurch dringt beim Waschvorgang die Arbeitsflüssigkeit (Wasch- oder Spüllauge) aus dem Laugenbehälter in den Waschtrommel-Innenraum und benetzt das dort befindliche Waschgut. Während des Schleudervorganges tritt die Flüssigkeit über die Durchflutungslöcher 3 wieder aus und wird aus dem Bodenbereich des Laugenbehälters in an sich bekannter Weise abgepumpt.The washing drum 1, which is rotatably mounted in the tub of a washing machine, has a cylindrical casing 2, which is provided in the usual way with a large number of flow holes 3 (perforations). During the washing process, the working liquid (washing or rinsing solution) from the tub penetrates through these flow holes into the interior of the washing drum and wets the laundry located there. During the spinning process, the liquid exits again via the flow holes 3 and is pumped out of the bottom area of the tub in a manner known per se.

Um das Zuführen der Arbeitsflüssigkeit aus dem Laugenbehälter in den Waschtrommel-Innenraum zu verbessern, ist die Trommelmantelfläche 2 wabenartig ausgebildet, wobei die Durchflutungslöcher 3 Teil der Waben 4 sind. Die Waben 4 sind dabei vorzugsweise als Prägungen 5 in Sechskantform ausgebildet. Die Waben 4 mit den Durchflutungslöchern 3 sind nach außen, d. h. zum Laugenbehälter hin gerichtet, so daß sich schräg nach außen führende Leitflächen 6 ergeben.In order to improve the supply of the working fluid from the tub into the washing drum interior, the drum shell surface 2 is designed like a honeycomb, with the flow holes 3 being part of the honeycombs 4. The honeycombs 4 are preferably designed as hexagonal-shaped embossings 5. The honeycombs 4 with the flow holes 3 are directed outwards, i.e. towards the tub, so that guide surfaces 6 leading diagonally outwards are created.

Die Sechskantform der Waben 4 mit den Durchflutungslöchern 3 erlaubt eine enge Aneinanderreihung der einzelnen Prägungen im Mantel 2 der Waschtrommel 1. Dadurch verbleiben keine Mantelflächen, die waagrecht zu der Fliehkraft des auszuschleudernden Wassers (Lauge) stehen. Die Arbeitsflüssigkeit trifft immer auf die schrägen, nach außen führenden Flächen 6 der Waben 4. Der Flüssigkeitsaustritt wird dadurch praktisch nicht mehr behindert. Die Festigkeit bzw. Stabilität der Waschtrommel wird aber wesentlich erhöht, so daß die Blechdicke des Waschtrommel-Mantels 2 reduziert und damit das Waschtrommel-Gewicht gesenkt werden kann.The hexagonal shape of the honeycombs 4 with the flow holes 3 allows the individual embossings in the casing 2 of the washing drum 1 to be arranged closely together. This means that there are no casing surfaces that are horizontal to the centrifugal force of the water (lye) to be spun out. The working fluid always hits the slanted, outward-facing surfaces 6 of the honeycombs 4. This means that the fluid outlet is practically no longer impeded. However, the strength or stability of the washing drum is significantly increased, so that the sheet thickness of the washing drum casing 2 can be reduced and the washing drum weight can therefore be reduced.
