Description

W aschmaschinentrommel Waschmaschinen mit einer elastischen Lagerung der um eine horizontale Achse rotierenden Wäschetrommel zur selbsttätigen Neutralisierung der Unwucht sind bekannt. Die Trommeln haben im Innern parallel zum Trommelmantel verlaufende Rippen. Es sind auch Waschmaschinen nicht neu, deren Trommeln mehrere in Achsrichtung sich verjüngende Rippen aufweisen. Die Rippen sind mit ihren Spitzen gegeneinander gerichtet, so daß ein Hin- und Herschieben des Waschgutes bewirkt wird.Washer drum Washing machines with an elastic bearing the laundry drum rotating around a horizontal axis for automatic neutralization the imbalance are known. The inside of the drums is parallel to the drum shell running ribs. Washing machines with several drums are not new either have ribs tapering in the axial direction. The ribs are with their tips directed against each other, so that the items to be washed are pushed back and forth will.

Von diesen bekannten Waschmaschinen unterscheidet sich die Waschmaschine gemäß der Erfindung dadurch, daß die Mitnehmerrippen der Wäschetrommel, die über elastische Tragstücke fliegend an einer auf der Antriebswelle sitzenden Tragscheibe befestigt ist, von der Beschickungsseite zur Lagerseite hin sich verjüngen.The washing machine differs from these known washing machines according to the invention in that the driver ribs of the laundry drum, which over elastic support pieces cantilevered on a support disk seated on the drive shaft is attached, taper from the loading side to the storage side.

Durch die keilförmigen Mitnehmerrippen, die sich zur Lagerseite hin verjüngen, wird die Wäsche nicht nur geteilt, sondern auch nach dem Lagerende der Trommel hin verschoben. Dabei verdichtet sich die Wäsche und verteilt sich gleichmäßiger auf den Umfang. Außerdem wird der Hebelarm der etwa noch verbleibenden Unwucht geringer.Due to the wedge-shaped driver ribs that extend towards the bearing side rejuvenate, the laundry is not only shared, but also after the end of storage Drum shifted. The laundry compacts and spreads more evenly on the scope. In addition, the lever arm of any remaining imbalance is reduced.

Die Anordnung einer elastischen Zentrierung bewirkt, daß die bei bestimmten Geschwindigkeiten, die nicht gerade die Schleudergeschwindigkeit sein muß, sondern auch eine etwas kleinere, auftretenden Schüttelbewegungen der Trommel gedämpft werden.The arrangement of an elastic centering causes the at certain Speeds that don't have to be the spin speed, but rather even a slightly smaller shaking motion of the drum that occurs can be dampened.

Dieses Schütteln der Maschine wird wohl auch bei den bekannten Anordnungen von elastischen Lagerungen weicher gemacht, kann aber gerade durch die elastische Anordnung besonders große Amplituden erreichen. Um dies zu verhindern, besitzt die Trommel eine elastische Zentrieruns.This shaking of the machine is probably also the case with the known arrangements Made softer by elastic mountings, but can be done precisely by the elastic ones Arrangement achieve particularly large amplitudes. To prevent this from happening, the Drum an elastic centering.

In der Zeichnung ist ein Ausführungsbeispiel der erfindungsgemäßen Wäschetrommel dargestellt.In the drawing is an embodiment of the invention Laundry drum shown.

Das mit 1 bezeichnete Teil in der Zeichnung (Schnitt A-B) zeigt die keilförmigen, von der Beschickungsseite zur Lagerseite hin sich verjüngenden Mitnehmerrippen am Umfang der Wäschetrommel 2. Die Wäschetrommel 2 ist durch die elastischen Tragstücke 3 an einer auf der Antriebswelle 6 sitzenden Tragscheibe 7 befestigt.With 1 part designated in the drawings (section AB) shows the wedge-shaped, from the feed side to the bearing side tapered drive ribs on the circumference of the washing drum 2. The laundry drum 2 is fixed by the elastic support pieces 3 of a person seated on the drive shaft 6 carrying disc 7 .

Das mit 4 bezeichnete Teil ist ein an der Trommel befestigter Ring, durch den im Zusammenwirken mit dem auf der Welle 6 sitzenden elastischen Teil 5 eine elastische Zentrierung der Trommel erfolgt.The part denoted by 4 is a ring fastened to the drum, by means of which, in cooperation with the elastic part 5 seated on the shaft 6 , an elastic centering of the drum takes place.
