Description
Die Erfindung betrifft einen leicht beweglichen, insbesondere tragbaren elektrischen Staubsauger, bei dem !Motor und Luftbeweger, gegebenenfalls auch Filtersack von einem gemeinsamen Gehäuse umschlossen werden.The invention relates to an easily movable, especially portable electric vacuum cleaner with the! motor and air mover, possibly also filter bag from a common one Enclosed housing.
Bei solchen Staubsaugern kann es vorkommen, daß iLis bisher allgemein aus Metall heriie>teiltf Gehäuse mit einem Pol di r elektrischen Stromzuleitung Schluß Kkommt und dann der ίο den Staubsauger Benützende elektrisiert wird, was besonders dann mit Gefahr verbunden ist, wenn die vielfach vorhandene Spannung von 2-20 Volt zum Betriebe des Staubsaugers benutzt wird.With such vacuum cleaners it can happen that until now iLis has generally been made of metal Housing with one pole of the electrical power supply line and then the conclusion ίο the person using the vacuum cleaner is electrified, which is particularly dangerous when the multiple existing tension of 2-20 volts used to operate the vacuum cleaner will.
D.is unvermeidliche Geräusch des Luftbewegers und auch dasjenige des laufenden Elektromotors überträgt sich ferner bei den bisher benützten Metallgehäusen in äußerst störender Weife nach außen. Der Hohlraum des Metallgehäuses wirkt dabei geradezu als Resonator. Es ist bekannt, Staubsauger zur Verringerung des Gewichtes und zur Dampfung des Geräusches mit Gehäuse aus Holzstoff zu versehen, ferner ist es in der allgemeinen Technik üblich, die bei elektrischen Stromanlagen vorhandenen Gehäuse aus nicht leitendem Baustoff von geeigneter Festigkeit herzustellen.D.is inevitable sound of the air mover and that of the running electric motor is also carried over to the previous ones used metal housings in an extremely annoying way to the outside. The cavity of the metal case acts as a resonator. It is known to reduce vacuum cleaners the weight and to dampen the noise with a housing made of wood pulp, It is also common in general technology to use those that are present in electrical power systems Manufacture housing from non-conductive building material of suitable strength.
Die Erfindung bringt nun für tragbare elektrische Staubsauger eine Verbesserung dadurch, daß das Gehäuse aus Korkmasse besteht. Die Eigenschaften von Korkmasse, einer durch Bindemittel zusammengehaltenen, gepreßten Masse aus geschrotetem Xaturkork, wirken sich gerade bei Staubsaugern und insbesondere bei tragbaren Staubsatigern besonders günstig und fortschrittlich aus, da erwiesenermaßen solche Masse neben großer Stoßfestigkeit auch eine gute schalldämpfende Wirkung hat.The invention now brings an improvement for portable electric vacuum cleaners in that that the housing is made of cork mass. The properties of cork mass, one through The pressed mass of crushed Xaturkork that is held together by binding agents has an effect especially with vacuum cleaners and especially with portable dust collectors and particularly cheap progressive, as it has been proven that in addition to great impact resistance, such a mass is also a has a good sound-absorbing effect.
Ein- Ausführungsbeispiel des Erfmdungsgegenstandes ist in der Zeichnung in einem Axialschnitt durch den Staubsauger dargestellt.An embodiment of the subject matter of the invention is shown in the drawing in an axial section through the vacuum cleaner.
Auf der Achse des Elektromotors α· sitzt in bekannter Weise der Luftbeweger b, der durch ein geeignetes Filter c die aus dem Saugstutzen d kommende Staubluft ansaugt und die von Staub befreite Luft zwecks Kühlung des Elektromotors über diesen leitet und durch die Mittelöffnung η einer Zwischenwand e und eine größere Anzahl von Löchern f im Gehäusedeckel g austreten läßt. The air mover b sits in a known manner on the axis of the electric motor α, which sucks in the dusty air coming from the suction nozzle d through a suitable filter c and directs the air, which has been freed of dust, over the electric motor for the purpose of cooling the electric motor and through the central opening η of a partition e and allows a larger number of holes f to escape in the housing cover g.
Das den Motor, Luftbeweger und Filter tragende Gehäuse Λ, ebenso wie dessen beide Deckel g und /, sind vollständig aus Korkmasse hergestellt, deren Außenflächen durch irgendwelche Bearbeitung o. dgl. ein gefälliges Aussehen oder Muster gegeben werden kann.The housing Λ carrying the motor, air mover and filter, as well as its two covers g and /, are made entirely of cork mass, the outer surfaces of which can be given a pleasing appearance or pattern by any processing or the like.
Befestigungsmittel, wie z. B. die das Filter tragende Stange k, die aus irgendwelchen Gründen durch das Gehäuse oder dessen Deckel hindurchgeführt sein müssen, können von außen durch Isolierkappen bedeckt sein. In der Zeichnung ist gezeigt, wie zur Befestigung der Stange k im Deckel i eine als Mutter ausgebildete Kappe m benützt ist.Fastening means, such as. B. the rod carrying the filter k, which for some reason must be passed through the housing or its cover, can be covered from the outside by insulating caps. The drawing shows how a cap m designed as a nut is used to fasten the rod k in the cover i.
Die Durchbildung der Inneneinrichtung ist von untergeordneter Bedeutung. Es könnte auch irgendein anderes Staubsaugersystem zusammen mit der Erfindung verwendet, werden. Wesentlich ist dagegen die Umhüllung des ganzen Systems mit einer schalldämpfenden und elektrisch isolierenden Korkmasse.The design of the interior is of minor importance. It could any other vacuum cleaner system can be used in conjunction with the invention. What is essential, however, is that the entire system be wrapped in a sound-absorbing material and electrically insulating cork mass.
