Description
Die Erfindung betrifft einen Staubsauger mit konischem, durch eine Feder gespannten Filter.The invention relates to a vacuum cleaner with a conical, tensioned by a spring Filter.
Der den meisten Staubsaugern anhaftende Nachteil besteht darin, daß der in einen Sack eingesaugte Staub diesen anfüllt und die Poren des Filters allmählich verstopft, wodurch die Saugkraft nachläßt.The disadvantage of most vacuum cleaners is that they come in a sack sucked in dust fills it up and gradually clogs the pores of the filter, causing the Suction power decreases.
Zur Vermeidung dieses Übelstandes wird to nunmehr das Filtertuch in Form eines Kegels mit der Spitze achsial gegen den Luftstrom angebracht, um ihn längs den Segelflächen des Filters entlangströmen zu lassen und dadurch den Staub von den Filterflächen abzuleiten, so daß er nicht gegen letztere in senkrechter Richtung auftrifft.To avoid this inconvenience, the filter cloth is now in the form of a cone with the tip attached axially against the air flow, around it along the sail surfaces to flow along the filter and thereby divert the dust from the filter surfaces, so that it does not hit the latter in a vertical direction.
Die Zeichnung zeigt den Sauger in einer Längsansicht.The drawing shows the vacuum cleaner in a longitudinal view.
Der die Staubkammer bildende Mantel a wird etwa durch einen hier nicht gezeichneten Bajonettverschluß mit seinem Wulstring r gegen einen Dichtungsring 0 geschoben, der am Ventüatorgehäuse gegen einen Wulstring q anliegt, wodurch die Kammer geschlossen ist. Der Luftstrom tritt durch das Saugrohr d in die Kammer und trifft zentrisch gegen die Spitze des Filterkegels Z auf, an dessen Kegelflächen gleichmäßig entlangströmend.The dust chamber forming a coat is r as by a not shown here bayonet closure with its bead ring against a sealing ring pushed 0, q is present at Ventüatorgehäuse against a bead ring, whereby the chamber is closed. The air flow enters the chamber through the suction tube d and hits the center of the tip of the filter cone Z, flowing evenly along its conical surfaces.
Der Filterkegel wird mit einem Ring m im Ansatzring φ des Ventilatorgehäuses festgeklemmt
und vermittels Kopfstück i und Feder k in straffer Spannung gehalten. Das
Gleitstück i wird von einem am Querstab g befestigten Stab h aufgenommen.
Dadurch, daß sich der den Filterkegel I tragende Spannstab h mit dem Kopfstück i
zentrisch gegen die Mündung des als Trichter in den Sammelraum hineinragenden Saugrohres
i richtet, wird der Luftstrom überall längs den Filterflächen entlanggeführt.The filter cone is clamped with a ring m in the attachment ring φ of the fan housing and held in tight tension by means of the head piece i and spring k. The slider i is taken up by a rod h attached to the transverse rod g .
Because the tension rod h carrying the filter cone I is centered with the head piece i against the mouth of the suction pipe i projecting into the collecting space as a funnel, the air flow is guided along the filter surfaces everywhere.
Die federnde Anordnung des Kopfstückes i hat auch den Vorteil der leichten Reinigung des Filters, ohne dieses vom Sauger abnehmen zu müssen, indem durch leichten Druck auf das Kopfstück i und schnelles Loslassen desselben ein Abschleudern des etwa anhaftenden Staubes erfolgt.The resilient arrangement of the head piece i also has the advantage of easy cleaning of the filter without having to remove it from the vacuum cleaner by throwing off any adhering dust by pressing lightly on the head piece i and releasing it quickly.
Die gereinigte Luft wird in bekannter Weise durch den Trichter η vermittels des" Ventilators b durch schlitzartige Öffnungen s im Gehäuse nach außen befördert.The cleaned air is conveyed in a known manner through the funnel η by means of the "fan b" through slot-like openings s in the housing to the outside.
Das trichterförmig weit in den Mantel a hineinragende Ende & des Saugrohres bewirkt, daß der abgelagerte Staub vom Luftstrom nicht wieder erfaßt wird.The funnel-shaped end & of the suction tube protruding far into the jacket a ensures that the deposited dust is not caught again by the air flow.
Das Gehäuse c umschließt den Motor, dessen Achse die Turbine b trägt. Durch Griff f kann der Staubsauger leicht und bequem über Polstermöbel u. dgl, geführt werden.The housing c encloses the motor, the axis of which carries the turbine b. The vacuum cleaner can be easily and comfortably guided over upholstered furniture and the like by means of handle f.
