Description
Gebläse, insbesondere für Staubsauger, mit an der Innenwand des Gehäuses angeordneten geräuschdämpfenden Stoffen Bei den Gebläsen wird vielfach das von dem Luftstrom hervorgerufene Geräusch störend empfunden, und zwar besonders bei den im Haushalt verwendeten Staubsaugern. Um dieses Geräusch zu verringern, ist es bekannt, einen Filzbelag zu verwenden, der an der Innenwand des Staubsaugergehäuses angebracht wird. Die Anbringung eines Filzbelages ist in vielen Fällen nur mit Schwierigkeiten durchführbar, besonders an unzugänglichen Stellen des Gebläsegehäuses, und der Filzbelag selbst ist nicht immer widerstandsfähig und wirksam genug.Blowers, in particular for vacuum cleaners, on the inner wall of the housing arranged noise-dampening materials. In the case of the blowers, the Airflow caused noise annoying, especially with the vacuum cleaners used in the household. To reduce this noise, it is known to use a felt pad attached to the inside wall of the vacuum cleaner housing will. The attachment of a felt covering is difficult in many cases feasible, especially in inaccessible parts of the fan housing, and the felt covering itself is not always resilient and effective enough.
Gemäß der Erfindung wird nun vorgeschlagen, an Stelle eines Filzbelages fein verteilte geräuschdämpfende Stoffe, z. B. Korkmehl oder Wollfasern usw., zu verwenden, die an der Innenwand des Gebläsegehäuses mittels eines Klebestoffes angebracht werden. Diese zStoffe haften fest an der vorher mit einem Klebestoff bestrichenen Innenwand und weisen eine wesentlich größere Härte als Filz auf, so daß sie der Abnutzung nicht so stark ausgesetzt sind wie der Filzbelag. Außerdem wird der auf diese Weise erzeugte Belag rauher und zerklüfteter als der Filzbelag, so daß die Geräusche leicht erstickt werden. Die Herstellung dieses Belages kann auf einfache Weise dadurch erfolgen, daß die fein verteilten geräuschdämpfenden Stoffe auf die vorher mit Lack oder einem anderen Klebestoll' bestrichene Innenwand geblasen werden, beispielsweise unter Verwendung der bekannten Spritzpistole. Hierdurch kann auch an den unzugänglichsten Stellen des Gehäuses ein völlig gleichmäßiger geräuschdämpfender Belag ohne die geringsten Schwierigkeiten erhalten werden, so daß die ganze Innenwand des Gehäuses die gleiche geräuschdämpfende Eigenschaft erhält.According to the invention, it is now proposed instead of a felt covering finely distributed noise-dampening substances, e.g. B. cork flour or wool fibers, etc., too use that attached to the inner wall of the fan housing by means of an adhesive will. These z-fabrics adhere firmly to the previously coated with an adhesive Inner wall and have a much greater hardness than felt, so they are the Are not exposed to wear and tear as much as the felt covering. In addition, the this way the surface was rougher and more rugged than the felt surface, so that the Noises are easily choked off. The production of this topping can be done in a simple manner Wise done in that the finely distributed noise-dampening substances on the inside wall coated beforehand with varnish or another glue stick are blown, for example using the known spray gun. This can also in the most inaccessible parts of the housing a completely uniform noise-dampening Covering can be obtained without the slightest difficulty, so that the entire inner wall the housing has the same noise-dampening properties.
Als geräuschdämpfende Stoffe sind besonders geeignet Korkmehl, Wollstaub, Faserstoff oder andere Textilstoffe, wie Seidenstaub usw. Auch kann man an Stelle von Korkmehl feine Sägespäne oder andere Stoffe von genügend geräuschdämpfender Wirkung verwenden.Cork flour, wool dust, Fiber or other textiles, such as silk dust, etc. You can also take it in place of cork flour, fine sawdust or other substances that are sufficiently noise-absorbing Use effect.
Die gemäß der Erfindung erfolgte Aus-. bildung des geräuschdämpfenden tberzuges ist von besonderer Bedeutung für die in fließender Fertigung hergestellten Staubsauger, da der zur Anfertigung der Gehäuse erforderliche Zeitaufwand hierdurch ganz erheblich verringert werden kann.The training carried out according to the invention. formation of the noise-dampening The coating is of particular importance for those manufactured in continuous production Vacuum cleaner, as this means the time required to manufacture the housing can be reduced quite considerably.
