Definitions
- the invention relates to a washing drum for a Washing machine, whose cylindrical jacket with a Variety of flood holes for the passage of the Working fluid is provided.
- Laundry drums of the type in question consist of a cylindrical mantle, which in the usual way with a Variety of flow holes is provided through which through the working fluid during the washing process from the Penetrate the tub into the interior of the washing drum can and by the during the spin cycle Working fluid then escapes again.
- the invention is based on this prior art based on the task of using simple measures Improve the supply of working fluid to the To reach through-flow holes in the washing drum jacket.
- the drum shell is honeycomb-shaped and the flood holes are part of the honeycomb.
- the honeycombs are embossed formed in hexagon shape.
- the washing drum 1, one in the tub Washing machine is rotatably mounted, has a cylindrical Coat 2, which in the usual way with a variety of Flooding holes 3 (perforations) is provided.
- Flooding holes 3 penetrate during the washing process the working fluid (washing or rinsing solution) from the Suds container in the washing drum interior and wetted the laundry located there.
- the liquid spins over the spin cycle Flood holes 3 again and is from the Bottom area of the tub in a manner known per se pumped out.
- the drum shell surface 2 is honeycomb-shaped, wherein the flood holes 3 are part of the honeycomb 4.
- the honeycomb 4 are preferably embossed 5 in hexagon shape educated.
- the honeycomb 4 with the throughflow holes 3 are outward, d. H. facing the tub, so that result in diagonally outwardly leading guide surfaces 6.
- the hexagonal shape of the honeycomb 4 with the flow holes 3 allows the individual to be closely aligned Embossments in the jacket 2 of the washing drum 1. This leaves them no lateral surfaces that are horizontal to the centrifugal force of the water to be ejected (lye).
- the Working fluid always meets the oblique, after outside leading surfaces 6 of the honeycomb 4.
- the liquid outlet is practically no longer hindered by this.
- the Strength or stability of the washing drum however significantly increased so that the sheet thickness of the washing drum jacket 2 reduced and thus the washing drum weight can be lowered.

Abstract
Description
Die Erfindung betrifft eine Waschtrommel für eine Waschmaschine, deren zylindrischer Mantel mit einer Vielzahl von Durchflutungslöcher zum Durchtritt der Arbeitsflüssigkeit versehen ist.The invention relates to a washing drum for a Washing machine, whose cylindrical jacket with a Variety of flood holes for the passage of the Working fluid is provided.
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.Laundry drums of the type in question consist of a cylindrical mantle, which in the usual way with a Variety of flow holes is provided through which through the working fluid during the washing process from the Penetrate the tub into the interior of the washing drum can and by the during the spin cycle Working fluid then escapes again.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, mit einfachen Maßnahmen eine Verbesserung der Zuführung der Arbeitsflüssigkeit zu den Durchflutungslöchern im Waschtrommelmantel zu erreichen.The invention is based on this prior art based on the task of using simple measures Improve the supply of working fluid to the To reach through-flow holes in the washing drum jacket.
Die Lösung dieser Aufgabe gemaß der Erfindung besteht darin, daß der Trommelmantel wabenartig ausgebildet ist und die Durchflutungslöcher Teil der Waben sind. In Weiterbildung der Erfindung sind die Waben als Prägungen in Sechskantform ausgebildet.This object is achieved according to the invention in that the drum shell is honeycomb-shaped and the flood holes are part of the honeycomb. In a further development of the invention, the honeycombs are embossed formed in hexagon shape.
Die mit der Erfindung 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 invention are u. a. in this to see that the working fluid quickly to the Flood holes and just as quickly through when spinning this is derived.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird anhand dieser nachfolgend näher beschrieben.An embodiment of the invention is in the drawing is shown and will be described in more detail below described.

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, one in the tub
Washing machine is rotatably mounted, has a
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.To supply the working fluid from the
To improve the tub in the washing drum interior
the
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
