Abstract

According to the method, a disinfectant is added to the stream of air passing through vacuum cleaners and to industrial suction cleaners to kill the bacteria and germs taken in and produced during the suction. The disinfection body to disinfect the exhaust air is bonded in a fixed body (12) and is placed in the air flow of the suction. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zur Desinfektion der Abluft von Staubsaugern.The invention relates to a method for disinfecting the exhaust air from vacuum cleaners.

Die Erfindung betrifft auch einen Desinfektionskörper zur Desinfektion der Abluft von Staubsaugern.The invention also relates to a disinfection body for disinfecting the exhaust air from vacuum cleaners.

Im Betrieb wird vom Staubsauger zusammen mit dem Staub und weiteren lose herumliegenden kleinen Gegenständen Luft angesaugt. Mit Hilfe eines Staubbeutels oder -sackes werden die angesaugten Festteilchen zurückgehalten, die als Transportmittel dienende Luft verlässt danach den Staubsauger im wesentlichen frei von Staub. Vom Filter oder Staubsack nicht zurückgehalten werden können Bakterien und schlechte Gerüche, welche entweder eingesaugt worden sind oder sich im Staubsauger gebildet oder vermehrt haben.In operation, the vacuum cleaner sucks in air together with the dust and other loose objects lying around. With the help of a dust bag or sack, the sucked-in solid particles are retained, and the air used as a means of transport then leaves the vacuum cleaner essentially free of dust. Bacteria and bad smells that have either been sucked in or that have formed or increased in the vacuum cleaner cannot be retained by the filter or dust bag.

Die mit der Abluft aus dem Staubsauger herausgeschleuderten Bakterien und Keime werden mit der Umgebungsluft vermischt und können bei Mensch und Tier zu Krankheit führen.The bacteria and germs thrown out of the vacuum cleaner with the exhaust air are mixed with the ambient air and can lead to illness in humans and animals.

Die Aufgabe der vorliegenden Erfindung besteht nun darin, ein Verfahren zu schaffen, mit dem der Ausstoss von bakteriellen Verunreinigungen mit der Abluft aus Staubsaugern verhindert werden kann.The object of the present invention is now to create a method with which the output of bak material contamination with the exhaust air from vacuum cleaners can be prevented.

Eine weitere Aufgabe der Erfindung besteht darin, einen Desinfektionskörper zu schaffen, mit welchem der Ausstoss von bakteriell verunreinigter Luft aus Staubsaugern verhindert werden kann.Another object of the invention is to provide a disinfection body with which the expulsion of bacterially contaminated air from vacuum cleaners can be prevented.

Nach der Erfindung werden diese Aufgaben gemäss den kennzeichnenden Merkmalen der Ansprüche 1 und 4 gelöst,According to the invention, these objects are achieved in accordance with the characterizing features of claims 1 and 4,

In einfacher und wirkungsvoller Weise können durch die Beigabe von Desinfektionsmittel im Staubsauger die in der Saugluft eintretenden und/oder die im Staubsack sich vermehrten Bakterien abgetötet werden, bevor diese mit der Abluft in die Umgebung gelangen können.In a simple and effective manner, by adding disinfectant in the vacuum cleaner, the bacteria entering the suction air and / or the bacteria multiplying in the dust bag can be killed before they can get into the environment with the exhaust air.

Die Verwendung eines in den Staubsack eingelegten oder als Filter ausgebildeten, ein Desinfektionsmittel enthaltenden Festkörpers erlaubt in einfacher Weise das Desinfektionsmittel zuzuführen.The use of a solid body inserted into the dust bag or designed as a filter and containing a disinfectant allows the disinfectant to be supplied in a simple manner.

Weitere vorteilhafte Ausführungen der Erfindung sind in den abhängigen Ansprüchen beschrieben.Further advantageous embodiments of the invention are described in the dependent claims.

Die Anordnung des das Desinfektionsmittel enthaltenden Festkörpers im Staubsack erweist sich besonders vorteilhaft, weil dadurch das Desinfektionsmittel nur dann abgegeben wird, wenn der Staubsauger im Betrieb steht. Während der Stillstandszeit entweicht praktisch kein Desinfaktionsmittel, so dass die Wirkung desselben auch erhalten bleibt, wenn der Staubsauger für längere Zeit unbenutzt bleibt.The arrangement of the solid containing the disinfectant in the dust bag proves to be particularly advantageous liable because the disinfectant is only released when the vacuum cleaner is in operation. Virtually no disinfectant escapes during the downtime, so that the effect of the disinfectant is retained even if the vacuum cleaner remains unused for a long time.

Anhand einer Zeichnung wird die Erfindung näher beschrieben. Es zeigen:

  • Figur 1 einen Längsschnitt durch einen Staubsauger,
  • Figuren 2-4 je einen ein Desinfektionsmittel enthaltender Festkörper.
The invention is described in more detail with reference to a drawing. Show it:
  • FIG. 1 shows a longitudinal section through a vacuum cleaner,
  • Figures 2-4 each a solid containing a disinfectant.

In einem Staubsauger 1 mit einem Gehäuse 2,einem Deckel 3 mit einem Schlauchanschluss 4 für einen Schlauch 5 und einem Abluftfilter 6 ist ein Staubbeutel oder -sack 7 eingesetzt. Zwischen dem Staubsack 7 und einem im Zentrum des Gehäuses 2 aufgehängten Motor M mit einem Sauggebläse 8 ist eine perforierte Wand 9 angebracht, welche den Staubsack 7 abstützt. Am Grund des Staubsackes 7 hat sich bereits eineSchicht mit Staub 10 abgelagert. An einer Klammer 11 befestigt, hängt ein ein Desinfektionsmittel enthaltender Festkörper 12 im Staubsack 7. Wenn der Festkörper 12 ohne Klammer 11 in den Staubsack 7 eingelegt ist, kann er selbstverständlich nur einmal eingesetzt werden, mit der Klammer 11 lässt er sich mehrmals verwenden.In a vacuum cleaner 1 with a housing 2, a cover 3 with a hose connection 4 for a hose 5 and an exhaust air filter 6, a dust bag or sack 7 is used. Between the dust bag 7 and a motor M suspended in the center of the housing 2 with a suction fan 8 there is a perforated wall 9 which supports the dust bag 7. At the bottom of the dust bag 7, a layer of dust 10 has already been deposited. Attached to a bracket 11, a solid 12 containing a disinfectant hangs in the dust bag 7. When the hard body 12 without clip 11 is inserted in the dust bag 7, it can of course only be used once, with the clip 11 it can be used several times.

Das Desinfektionsmittel kann in einem zigarettenfilter- ähnlichen Zylinder 13 (Figur 2) oder in einem Weichkarton, Filz oder PVC 14 (Figur 4) enthalten sein. Es besteht auch die Möglichkeit, das Desinfektionsmittel ähnlich einer Kapferkugel herzustellen, welche sich allmählich auflöst.The disinfectant can be contained in a cylinder 13 similar to a cigarette filter (FIG. 2) or in a soft cardboard, felt or PVC 14 (FIG. 4). There is also the possibility of producing the disinfectant similar to a caper ball, which gradually dissolves.

Selbstverständlich kann der das Desinfektionsmittel enthaltende Festkörper 12 ausser in einem Haushaltstaubsauger 1 mit gleicher Wirkung in Industriestaubsaugern und allgemein in Industrieabsaugungen aller Art eingesetzt werden, unabhängig von deren Funktionsprinzip.Of course, the solid 12 containing the disinfectant can be used with the same effect in industrial vacuum cleaners and in general in all types of industrial vacuum cleaners, regardless of their functional principle, except in a household vacuum cleaner 1.
