Description
Trommel für Bei den bekannten Wäschezentrifugen sind die Löcher für den Austritt des Wassers aus der Trommel von aussen nach innen ausgestanzt und haben deshalb auf der innern Seite einen scharfen Rand, der manchmal sogar in einen nach innen umgebogenen, scharfen Grat ausartet. Dies ist für die Wäsche von grossem Nachteil, da die feine Wäsche, welche durch die Zentrifugalkraft in die Löcher hineingetrieben wird, an dem scharfen Grate hängen bleibt und zerreisst.
Gegenstand vorliegender Erfindung ist eine Trommel für Wäschezentrifugen, deren Entwässerungslöcher von innen nach aussen ausgestanzt sind, und zwar so, dass im Innern der Trommel die Löcher eine Abrundung be sitzen, welche verhindert, dass die Wäsche hängen bleibt und zerreisst. Ferner ist diese Form des Lochrandes ein grosser Vorteil für den Austritt des Wassers, es entsteht keine flache Ebene zwischen den einzelnen Löchern, sondern eine Wölbung, wodurch das Wasser seinen Austritt auf dem kürzesten Wege findet. Das Trocknen der Wäsche wird da durch viel rascher und sicherer möglich gemacht.
Die von innen nach aussen ausgestanzten Löcher sind auf der Aussenseite der Trommel von einem Wulst umgeben, der zur Verstei fung der Wandung dient. Es kann daher viel dünneres Blech zur Anfertigung der Trommel verwendet werden.
Auf der beiliegenden Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, und zwar ist: Fig. 1 eine Ansicht der abgewickelten Trommel, Fig. 2 ein Schnitt in vergrössertem Mass stabe durch die gestanzten Löcher.
Es bedeuten 1 die Trommelwandung, 2 die Löcher, 3 die Wülste; 4 die Abrundungen der Lochränder auf der Innenseite der Trom mel, 5 ein Wäschestück.
Die Löcher können rund, oval, länglich oder in sonst geeigneter Form ausgestanzt werden und in Abständen, welche für den Austritt des Wassers den geringsten Wider stand ergeben, ohne die Steifheit der Trommel unzulässig zu beeinträchtigen.
Drum for In the known laundry centrifuges, the holes for the water to exit the drum are punched out from the outside to the inside and therefore have a sharp edge on the inside, which sometimes even degenerates into an inwardly bent, sharp ridge. This is a major disadvantage for the laundry, since the fine laundry, which is driven into the holes by centrifugal force, gets caught on the sharp burrs and tears.
The present invention relates to a drum for laundry centrifuges, the drainage holes of which are punched out from the inside to the outside, in such a way that the holes inside the drum are rounded to prevent the laundry from getting stuck and tearing. Furthermore, this shape of the edge of the hole is a great advantage for the exit of the water, there is no flat plane between the individual holes, but a curvature, whereby the water can find its exit on the shortest path. The drying of the laundry is thereby made much faster and safer.
The holes punched out from the inside out are surrounded on the outside of the drum by a bead which serves to stiffen the wall. Much thinner sheet metal can therefore be used to make the drum.
In the accompanying drawing, an embodiment of the invention is shown, namely: Fig. 1 is a view of the unwound drum, Fig. 2 is a section on an enlarged scale rod through the punched holes.
1 denotes the drum wall, 2 the holes, 3 the beads; 4 the rounding of the hole edges on the inside of the drum, 5 a piece of laundry.
The holes can be round, oval, oblong or punched out in any other suitable shape and at intervals that result in the least resistance for the leakage of the water without unduly impairing the rigidity of the drum.
