Description
Die Erfindung betrifft einen Saugschlauch für einen Staubsauger. Im Weiteren betrifft die Erfindung auch einen Staubsauger mit einem solchen Saugschlauch.The invention relates to a suction hose for a vacuum cleaner. Furthermore, the invention also relates to a vacuum cleaner with such a suction hose.
Ein Saugschlauch für einen Staubsauger ist speziell bei Bodenstaubsaugern an sich bekannt. Mittels des Saugschlauchs wird der Geräteteil des Bodenstaubsaugers, welcher das zum Erzeugen eines Unterdrucks bestimmte Sauggebläse umfasst, mit einer üblicherweise am Ende eines Saugrohrs befindlichen Bodendüse verbunden. Der mittels des Sauggebläses im Betrieb erzeugte Unterdruck wirkt dann im Bereich eines Saugmunds der Bodendüse, so dass in an sich bekannter Art und Weise durch Bewegen der Bodendüse ein Absaugen eines jeweiligen Untergrunds möglich ist.A suction hose for a vacuum cleaner is known per se, in particular for floor vacuum cleaners. By means of the suction hose, the device part of the cylinder vacuum cleaner, which comprises the suction fan intended to generate a negative pressure, is connected to a floor nozzle which is usually located at the end of a suction pipe. The vacuum generated during operation by means of the suction blower then acts in the area of a suction mouth of the floor nozzle, so that suction of a respective substrate is possible in a manner known per se by moving the floor nozzle.

Genauso wie bei anderen Haushalts- und Elektrogeräten tritt auch bei Staubsaugern deren Energieeffizienz mehr und mehr in den Vordergrund. Der Erfindung stellt sich somit das Problem, den Wirkungsgrad eines Staubsaugers zu erhöhen. Der im Folgenden beschriebene Ansatz soll hierzu einen Beitrag leisten.Just like with other household and electrical appliances, the energy efficiency of vacuum cleaners is becoming more and more important. The invention thus poses the problem of increasing the efficiency of a vacuum cleaner. The approach described below is intended to contribute to this.
Erfindungsgemäß wird dieses Problem durch einen Saugschlauch für einen Staubsauger mit den Merkmalen des Patentanspruchs 1 gelöst.According to the invention this problem is solved by a suction hose for a vacuum cleaner with the features of claim 1.
Der Saugschlauch weist in üblicher Art und Weise ein erstes und ein zweites Ende auf, wobei die beiden Enden im Folgenden zur Unterscheidung als Geräteseite und als Griffseite bezeichnet werden. Bei einem an einen Staubsauger angeschlossenen Saugschlauch befindet sich die Geräteseite des Saugschlauchs im Vergleich zur Griffseite nahe bei einem von dem Staubsauger umfassten Sauggebläse. Die Griffseite des Saugschlauchs wird beim Saugbetrieb vom Verwender des Staubsaugers bewegt, nämlich üblicherweise mittels eines Handgriffs. An den Handgriff schließt unmittelbar oder mittelbar, zum Beispiel unter Verwendung eines sogenannten Saugrohrs, eine Bodendüse an. Bei dem hier vorgeschlagenen Saugschlauch ist vorgesehen, dass ein Durchmesser des Saugschlauchs ausgehend von einem ersten Durchmesser auf der Griffseite oder im Bereich der Griffseite in Richtung auf die Geräteseite abnimmt. Aufgrund des ausgehend von dem ersten Durchmesser auf der Griffseite oder im Bereich der Griffseite in Richtung auf die Geräteseite abnehmenden Durchmessers des Saugschlauchs werden der hier vorgeschlagene Saugschlauch - auch in Unterscheidung zu dem Saugschlauch gemäß der
Der Vorteil der Erfindung besteht darin, dass mittels der beschriebenen Ausgestaltung des Saugschlauchs eine Optimierung im Hinblick auf die Luftleistung und die Staubaufnahme des Staubsaugers erreichbar ist, ohne dafür die zum Betrieb des Sauggebläses aufgenommene elektrische Leistung zu erhöhen. Indem der Durchmesser des Saugschlauchs in Richtung auf die Geräteseite abnimmt, kann der Saugschlauch zudem in einem Durchmesser enden, der einen unmittelbaren Anschluss an ein Gerätegehäuse oder eine geräteseitige Anschlussvorrichtung erlaubt. Der hier vorgeschlagene Saugschlauch ist damit unmittelbar auch zusammen mit Seriengeräten sowie bereits in Gebrauch befindlichen Staubsaugern verwendbar.The advantage of the invention is that by means of the described configuration of the suction hose, an optimization with regard to the air performance and the dust pick-up of the vacuum cleaner can be achieved without increasing the electrical power consumed for operating the suction fan. As the diameter of the suction hose decreases towards the device side, the suction hose can also end in a diameter that allows a direct connection to a device housing or a device on the device side. The suction hose proposed here can thus also be used directly together with series devices and vacuum cleaners that are already in use.

Such a suction hose has the anticonical geometry only in the area of the middle section on. With such a suction hose, too, a diameter of the suction hose decreases from a first diameter on the handle side in the direction of the device side. Even with such an embodiment of the suction hose, it is ensured that, owing to the smallest diameter on the device side, it can be used directly with standard devices and with vacuum cleaners that are already in use.
