Description

Die Erfindung betrifft eine Staubsaugerdüse mit einem auf dem zu reinigenden Gegenstand allseitig aufliegenden Rand und mit Rippen im Innern. Von den bekannten Düsen dieser Art unterscheidet sich die Düse gemäß dem Gegenstande der Erfindung dadurch, daß die Rippen .parallel oder annähernd parallel zur Bewegungsrichtung des Staubsaugers verlaufen und nur mit ihren äußeren Enden bündig mit dem Düsenrand liegen, im Innern der Düse dagegen bogenförmig nach der Saugöffnung hin verlaufen. Der Vorteil einer derartigen Rippenanordnung gegenüber einer solchen, bei der beispielsweise die Rippen quer zur Bewegungsrichtung des Staubsaugers verlaufen, besteht zunächst darin, daß beispielsweise ein zu reinigender Teppich kalottenförmig in das Innere der Düse eingesaugt wird, wodurch nachweisbar auch beispielsweise unter dem Teppich ■ liegender so Staub mit abgesaugt wird. Außerdem wird eine große Fläche des zu reinigenden Gegenstandes gleichzeitig unter Sog gesetzt, so daß infolge der in Bewegungsrichtung des Staubsaugers angeordneten Rippen beim Hinundherbewegen des Saugers die Saugluft genügend Zeit hat, den Staub und sonstige Fremdkörper anzusaugen, was bei einer Rippenanordnung quer zur Bewegungsrichtung nicht der Fall ist. Während bei einer solchen Rippenanordnung nämlich durch die Rippen unterteilte Düsenkammern gebildet werden, führenbei der Rippenanordnung gemäß dem Gegenstande der Erfindung die durch sie gebildeten Saugkammern immer nach einer Stelle, nämlich nach der Saugöffnung hin. Auf der Zeichnung ist ein Ausführungsbeispiel der Düse veranschaulicht, und zwar zeigen:The invention relates to a vacuum cleaner nozzle with an object to be cleaned rim on all sides and with ribs on the inside. From the known nozzles of this type differs the nozzle according to the subject invention in that the ribs .Parallel or approximately parallel to the direction of movement of the vacuum cleaner and only with their outer ends flush with the edge of the nozzle, but inside the nozzle run in an arc towards the suction opening. The advantage of such a rib arrangement compared to one in which, for example, the ribs are transverse to the direction of movement run of the vacuum cleaner, consists initially in the fact that, for example, a to be cleaned Carpet is sucked into the inside of the nozzle in the shape of a dome, which is also detectable For example, dust lying under the carpet is extracted with it. In addition, will a large area of the object to be cleaned is simultaneously subjected to suction, so that due to the ribs arranged in the direction of movement of the vacuum cleaner when moving to and fro the suction air has enough time to suck in the dust and other foreign bodies, which is the case with a rib arrangement transversely to the direction of movement is not the case. While with such a rib arrangement namely, nozzle chambers divided by the ribs are formed, result in the rib arrangement according to the subject matter of the invention, the suction chambers formed by them always towards one point, namely towards the suction opening. On the drawing is a Embodiment of the nozzle illustrated, namely show:

Abb. ι die Düse von unten gesehen, Abb. 2 im Querschnitt nach der Linie A-B der Abb. 1.Fig. Ι the nozzle seen from below, Fig. 2 in cross section along the line AB in Fig. 1.

Der Umriß 3 der Düse, der kreis-, ovalförmig, eckig oder sonstwie gestaltet sein kann, ist bei dem Ausführungsbeispiel doppelfächerartig gedacht und liegt auf dem zu reinigenden Gegenstand, z. B. einem Teppich 20, auf, während die noch zu beschreibenden Rippen 4 ein Ansaugen des Teppichs, wie Abb. 2 zeigt, sowohl in der Zeichenebene wie auch quer dazu bogenförmig in das Innere der Düse hinein erlauben. Sie laufen zu diesem Zweck außen in den Umriß 3 aus (vgl. Abb. 2), während sie nach der Mitte hin gewölbt ausgebildet sind und am Rande der Saugöffnung 1 wieder zum Aufliegen auf die zu reinigende Unterlage kommen. Dementsprechend wird man auch die Deckenwändungen 5 der durch die Rippen 4 gebildeten Kanäle, wie Abb. 2 zeigt, gewölbt ausbilden. Durch die Saugöffnung i, in welche (vgl. Abb. 1) bei 21 die Kanäle münden, wird die Luft in das Innere des Gehäuses abgesaugt. Unmittelbar hinter dem Loch befindet sich das Flügelrad 6, das durch den Motor 7 .angetrieben wird und in einem ihm angepaßten Gehäuse 8 angeordnet ist. Der angesaugte Staub gelangt durch eine Öffnung 9 in die Staubkammer 10.The outline 3 of the nozzle, which is circular, oval-shaped, Can be angular or otherwise designed, is double fan-like in the embodiment thought and lies on the object to be cleaned, z. B. a carpet 20, while the yet to be described ribs 4 sucking in the carpet, as Fig. 2 shows, both in the plane of the drawing as well as across it in an arc shape into the interior of the nozzle allow. For this purpose, they run out into the outline 3 (see Fig. 2), while they are curved towards the center and at the edge of the suction opening 1 come to rest on the surface to be cleaned. Accordingly, will the ceiling walls 5 of the channels formed by the ribs 4, as shown in Fig. 2 shows, arched form. Through the suction opening i, in which (see. Fig. 1) at 21 the Open channels, the air is sucked into the interior of the housing. Immediately behind the hole is the impeller 6, which is driven by the motor 7 and in a housing 8 adapted to it is arranged. The sucked in dust passes through a Opening 9 in the dust chamber 10.
