Description

Staubfilter fe.-#faubsauger Die Erfindung betrifft ein Staubfilt#er für Staubsauger mit einer oder inehreren aus Pflanzenfaserstoffen bestehenden Filterschichten. Es soll dadurch die Ver#venduncr von Stoffsäcken vermieden und ein billiger und dennoch guter Ersatz geboten werden. Es ist bekannt, als Filtexn-uttel Papiersäcke zu. verwenden, die mit Durchlochungen versehen sind. Die Filtexwirkung bei diesen ist je- doch ungenügend, da nur eine gewisse Anzahl von Durchtrittsöffnungen vorhanden schl kann und diese außerdem leicht verstopft werden können. Ferner muß zur Herstellung solcher Papierfiltersäcke verhältnismäßigstarkes und daher teueres Papier venvendet werden. Es ist ferner schon bekannt, Watte Moder ähnliche Pflanzenfaserstoffe als Filtermittel vorzusehen; diese stellen jedach eine, formlose Masse dar und sind daher für sich als s!elbständigeKörper nicht verwendbar. Außerdem bestehen diese -watteartigien Filtermittel aus teuerem, im Iffland nicht vorhandenem Rohstoff.The invention relates to a dust filter for vacuum cleaners with one or more filter layers made of vegetable fibers. The aim is to avoid the deterioration of cloth sacks and to offer a cheap, yet good replacement. It is known as filtexn-uttel paper sacks too. use that are provided with perforations. The Filtexwirkung these is still insufficient JE, as only a certain number of through-holes may exist schl and these can be also easily clogged. Furthermore, relatively strong and therefore expensive paper must be used for the production of such paper filter bags. It is also already known to provide cotton wool similar to vegetable fibers as filter media; these each represent a formless mass and are therefore not usable as independent bodies. In addition, these cotton wool-like filter media are made from expensive raw material that is not available in Iffland.

Das Neue der Erfindung besteht darin, daß das Staubfilter Baus vliesartig gelegten Zellst#offen besteht. Die Filter weisen Scheiben-, Trichter- oder Zylinderforrn auf und liegen an einem entsprechend ausgebildeten Sieb 0.,dgl. an. Um die Festigkeit des Filters zu erhöhen und die Oberflächen-wirkung zu steigern, können die Staubfilterscheiben erfindüngsgemäß profiliert gepreßt sein. Die besonders fortschrittliche Wirrkung des erfinfindungsgemäßen Filters beruht in der sehr billigen Herstellung, bei der inländischeRohstoffe Verwendung finden.The novelty of the invention is that the dust filter Baus fleece-like placed Zellst # is open. The filters have a disc, funnel or cylinder shape and lie on a correspondingly designed sieve 0., like. at. About the strength the filter and the surface effect can be increased by the dust filter discs be pressed according to the invention profiled. The particularly advanced effect the filter according to the invention is based on the very cheap production in which domestic raw materials are used.

Das Einsetzen eines aus Stoffgewebe b#estehenden Filtersackes in den Staubsauger C kommt damit in Wegfall. Nach jedem Gebrauch des Staubsaugers wird die erfindungsgemäße Filterscheibe, Trichter :o. dgl. mit dem daxin enthaltenen Staub weggeworfen. Das aus vliesartig gelegten Zellstoff-en be- stehende Filter ist äußerst luftdtircl-Aässi#g, so daß infolge der jedesmal frisch eingelegten Filterscheiben o. dgl. eine gute Saugwirkung ZD erzielt wird.There is no longer any need to insert a filter bag made of fabric into the vacuum cleaner C. After each use of the vacuum cleaner, the filter disk, funnel according to the invention: o. Like. Thrown away with the dust contained in the daxin. The loading properties of non-woven filter Laid-en pulp is extremely luftdtircl-Aässi # g, so that each o due to the newly inserted filter discs. The like. A good suction ZD is obtained.

In der Zeichnung ist ein Schema eines aus vielen Staubsaugerformen herausgegriffenen Ausführungsbeispiels dargestellt.In the drawing is a schematic of one of many shapes of vacuum cleaners Selected embodiment shown.

Das Staubsaugergehäuse -i enthält in bekannter Weise einen - Motor 5 und ein Gebläse 6. Der Ansaugeweg ist durch Pfeile angedeutet. Ein beispielsweise trommelförmiger Einsatz 2 ist mit einem Siebboden 4 versehen, auf dem ein aus vliesartig gelegten Zellstoffen bestehendes Staubfilter 3 aufliegt. !Dieses ist durch geeignete Haltemittel, wie Spannring, Anschläge o. dgl., festgehalten. Die Staubfilter 3 können außer der Scheibenform auch die Form von Säcken, Trichtern o. dgl. haben. Die. Erfindung ist sowohl bei Staubsaugern im Hausgebrauch als auch bei solchen für industrielle Anlagen verwendbar.The vacuum cleaner housing -i contains in a known manner a - motor 5 and a fan 6. The suction path is indicated by arrows. A drum-shaped insert 2, for example, is provided with a sieve bottom 4, on which a dust filter 3 made of cellulose material laid like a fleece rests. ! This is held in place by suitable holding means, such as clamping rings, stops or the like. In addition to the shape of a disk, the dust filter 3 can also be in the form of bags, funnels or the like. The. The invention can be used in both domestic and industrial vacuum cleaners.
