Abstract

The method and the apparatus serving for carrying out the method allow the combatting of domestic mites in a simple and environmentally friendly manner and without the use of chemical substances. For this purpose, a vacuum cleaner nozzle, which is known per se, interacts with a source of hot air in such a way that the site to be treated is subjected in one operation to the short-term effect of hot air with subsequent suction. The vacuum cleaner nozzle bears a hot air blower (7), through which heated air flows via a blower slot (8), located in front of the suction channel (6), onto the area to be cleaned.

Description

Die Erfindung bezieht sich auf ein Verfahren zur Bekämpfung der Hausstaubmilbe und eine Vorrichtung zur Durchführung dieses Verfahrens.The invention relates to a method for controlling the dust mite and an apparatus for performing this method.

Hausstaubmilben finden sich bekanntlich in Matratzen, Polstermöbeln, Teppichen und in fast allen textilen Gegenständen, und zwar bis zu 10.000 pro m². Für viele Menschen stellen die Hausstaubmilben seit langem ein Problem dar, da sie darauf mit Allergien reagieren, die allerdings nicht allein durch die Milben selbst, sondern hauptsächlich durch deren Exkremente , die etwa das 200fache ihres Körpergewichts betragen, ausgelöst werden. Das Problem der auf diese Exkremente allergisch reagierenden Personen ist erst dadurch dauerhaft zu lösen, daß die Hausstaubmilben gezielt vernichtet werden.Dust mites are known to be found in mattresses, upholstered furniture, carpets and in almost all textile objects, up to 10,000 per m². Dust mites have long been a problem for many people because they react to them with allergies, which are not only caused by the mites themselves, but mainly by their excrement, which is around 200 times their body weight. The problem of people who are allergic to these excrement can only be solved permanently by destroying the house dust mites.

Bis jetzt wurde die Hausstaubmilbe durch chemische Mittel bekämpft. Dies setzt jedoch eine gewisse Erfahrung bzw. ein geschicktes Manipulieren mit der chemischen Substanz voraus, sowie auch Kenntnisse dahingehend, daß die zu behandelnden Textilien chemisch nicht angegriffen werden. Es ist auch nicht für jedes chemische Mittel eine Unbedenklichkeit in gesundheitlicher Hinsicht erwiesen.So far, the house dust mite has been controlled by chemical means. However, this requires a certain amount of experience or a skillful manipulation with the chemical substance, as well as knowledge that the textiles to be treated are not chemically attacked. It has also not been shown to be harmless to health in every chemical agent.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren sowie eine Vorrichtung der genannten Art zu schaffen und dadurch eine einfache Handhabung zu ermöglichen, die Verwendung chemischer Stoffe zu vermeiden und umweltfreundlich zu arbeiten.The invention has for its object to provide a method and an apparatus of the type mentioned and thereby enable easy handling, avoid the use of chemical substances and work in an environmentally friendly manner.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine an sich bekannte Staubsaugerdüse derart mit einer Heißluftquelle zusammenwirkt, daß die zu behandelnde Stelle in einem Arbeitsgang der kurzzeitigen Einwirkung von Heißluft mit nachfolgender Absaugung unterworfen wird.This object is achieved in that a known vacuum cleaner nozzle interacts with a hot air source in such a way that the area to be treated is subjected in one operation to the brief exposure to hot air with subsequent suction.

Die Vorrichtung zur Durchfuhrung dieses Verfahrens ist gekennzeichnet durch eine aus Oberteil und Unterteil bestehende Staubsaugerdüse, die über ein Gelenk und einen Drehgelenkstutzen an einem Saugrohr angebracht ist, wobei im Unterteil über die Düsen-Arbeitsbreite ein Saugkanal verläuft und die Staubsaugerdüse selbst ein Heißluftgebläse trägt, durch welches über einen vor dem Saugkanal liegenden Blasschlitz erhitzte Luft auf die zu säubernde Fläche strömt.The device for carrying out this method is characterized by a vacuum cleaner nozzle consisting of an upper part and a lower part, which is attached to a suction pipe via a joint and a swivel joint, a suction channel running in the lower part across the nozzle working width and the vacuum cleaner nozzle itself carrying a hot air blower which flows through a heated air slot in front of the suction channel onto the surface to be cleaned.

Vorteilhafte Weiterbildungen ergeben sich aus den Merkmalen der Ansprüche 3 und 4.Advantageous further developments result from the features of claims 3 and 4.

Nächstehend ist eine bevorzugte Ausführungsform der erfindungsgemäßen Vorrichtung mit Bezug auf die schematische Zeichnung beispielsweise näher beschrieben; die einzige Figur zeigt eine Seitenansicht der erfindungsgemäßen Vorrichtung.A preferred embodiment of the device according to the invention is described in more detail below with reference to the schematic drawing, for example; the single figure shows a side view of the device according to the invention.

Eine aus Oberteil (1) und Unterteil (2) bestehende Staubsaugerdüse ist über ein Gelenk (3) und einen Drehgelenkstutzen (4) an einem Saugrohr (5) angebracht. Im Unterteil (2) verläuft über die Düsen-Arbeitsbreite ein Saugkanal (6) und die Staubsaugerdüse selbst trägt ein Heißluftgebläse (7), durch welches über einen vor dem Saugkanal (6) liegenden Blasschlitz (8) erhitzte Luft auf die zu säubernde Fläche strömt.A vacuum cleaner nozzle consisting of upper part (1) and lower part (2) is attached to a suction pipe (5) via a joint (3) and a swivel joint (4). In the lower part (2), a suction channel (6) runs over the nozzle working width and the vacuum cleaner nozzle itself carries a hot air blower (7) through which heated air flows onto the surface to be cleaned via a blow slot (8) located in front of the suction channel (6) .

Diese Heißluftbehandlung ist notwendig, damit die Milbe ihre Verklammerung mit textilen Fasern löst. Eine rein mechanische Bearbeitung führt daher nicht zu dem gewünschten Erfolg. Dabei hat sich gezeigt, daß die Temperatur der aus dem Blasschlitz (8) austretenden Luft vorzugsweise im Bereich von 60 bis 70°C liegen muß, weil dadurch einerseits die Milbe absaugbar gemacht und andererseits die textile Faser noch nicht angegriffen wird.This hot air treatment is necessary so that the mite releases its clinging with textile fibers. A purely mechanical processing therefore does not lead to the desired success. It has been shown that the temperature of the air emerging from the blow slot (8) must preferably be in the range from 60 to 70 ° C., because on the one hand this makes the mite extractable and on the other hand the textile fiber is not yet attacked.

Das Heißluftgebläse (7) wird durch ein Netzkabel (9) mit Strom versorgt; es kann aber auch unabhängig vom Stromnetz von einer (nicht dargestellten) Batterie, die gegebenenfalls wiederaufladbar ist, gespeist werden.The hot air blower (7) is powered by a power cable (9); however, it can also be powered independently of the power supply by a battery (not shown), which is optionally rechargeable.

Die Erfindung vereint zwei Funktionen, nämlich die Bekämpfung der Hausstaubmilbe durch erhöhte Temperaturen, so daß sich deren Verklammerung mit textilen Fasern löst, gefolgt von einem Absaugvorgang, der diese Milben dann - zusammen mit ihren Exkrementen - absaugt. Die beschriebene Vorrichtung arbeitet gemäß der ihr zugrundeliegenden Aufgabe umweltfreundlich, denn sie hinterläßt keine chemischen Umwandlungsprodukte oder sonstige Bearbeitungsspuren.The invention combines two functions, namely the control of the house dust mite by elevated temperatures, so that its clinging with textile fibers is released, followed by a suction process, which then - together with its excrement - sucks these mites off. The device described operates in an environmentally friendly manner in accordance with the task on which it is based, since it does not leave any chemical conversion products or other processing traces.
