Abstract

It is known to dry the hands in lavatories or the like with a stream of hot air. The stream of hot air also sucks in any bacteria present and blows them on to the hands to be dried. In order to avoid this disadvantage it is proposed, according to the invention, that the hot air drier be provided with a filter that separates bacteria and/or spores. The filter pack comprises activated charcoal and soda lime. The exchangeable filter pack is put on the hot air drier and/or arranged downstream thereof.

Description

Beschreibung und Erläuterung zur Patent- undDescription and explanation of the patent and

Hi.lfsgebrauchsmusteranmeldung "Händetrockner für Toilettenräume Es ist bekannt, Hände in Toilettenräumen durch einen Warmluftstrahl zu trocknen.Hi.lfs utility model registration "hand dryers for toilets Es it is known to dry hands in toilet rooms with a jet of warm air.

Bekannt ist jedoch auch, daß gerade in Toiletten eine mit Bakterien angereicherte Luft zwangsläufig vorhanden ist.However, it is also known that especially in toilets one with bacteria enriched air is inevitably present.

Diese Luft wird nun angesaugt, angewärmt und bewußt den Händen und dem Menschen, insbesondere durch die Aufprallwirkung auf die Hände, bis in den Atembereich zugeführt.This air is now sucked in, warmed and consciously the hands and humans, especially due to the impact on the hands, up to the breathing area fed.

Um diesen Nachteil der Bazillenzuführung im Bereich des Menschen zu verhindern, wird erfindungsgemäß vorgeschlagen, einen Bazillenatscheider dem Heißluftgerät vorzuschalten.To this disadvantage of the bacilli supply in the area of the humans too prevent, is according to the invention suggested a bacillus separator upstream of the hot air device.

In der beiliegenden Zeichnung ist dargestellt: Abb. A mit (1) das Handluftgerät; mit (2) ein auf dem Handluftgerät aufgesetzter bakterizider Filter, der erfindungsgemäß aus A-Kohle und Natronkalk besteht und leicht auswechselbar ist.The attached drawing shows: Fig. A with (1) das Hand held air device; with (2) a bactericidal filter placed on the hand-held air device, which according to the invention consists of activated carbon and soda lime and is easily exchangeable is.

Da es in den Toiletten in der Regel sehr feucht ist, und Feuchtigkeitsansammlungen in der abscheidenden Chemisorptionsmasse zu einer vorzeitigen Inaktivierung führt, wird erfindungsgemäß weiterhin vorgeschlagen, die bazillen- bzw. sporenabscheidenden Filterelemente auf die Warmluftseite des Gerätes zu setzen.Because it is usually very humid in the toilets and moisture builds up leads to premature inactivation in the separating chemisorption mass, it is further proposed according to the invention, the bacillus or spore-separating Place filter elements on the warm air side of the device.

In der beiliegenden Zeichnung ist dargestellt: Abb. B mit (1) das Warmluftgerät; mit (2) das auswechselbare Filterpaket, welches erfindungsgemäß aus Natronkalk und A-Kohle besteht.The attached drawing shows: Fig. B with (1) das Hot air device; with (2) the replaceable filter package, which according to the invention consists of soda lime and charcoal.

Erfindungsgemäß kann natürlich zusätzlich auch noch auf der Saugseite ein zusätzliches Filterpaket, z.B.According to the invention, of course, it can also be done on the suction side an additional filter package, e.g.

aus Natronkalk, eingesetzt werden, das bei hoher relativer Feuchte eine gute Reaktion zeigt.made of soda lime, which can be used at high relative humidity shows a good response.
