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.As is well known, house dust mites can 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 excrements 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.

Aus der FR-A-2 601 239 ist ein Staubsauger bekannt, der mit einer Düse ausgestattet ist, die mit einem Saugkanal sowie einem davorliegenden Blasschlitz ausgestattet ist. Die durch den Saugkanal und den dazugehörigen Saugrohr angesaugte Luft wird zum Saugmotor geführt, dort filtriert und mit Hilfe einer Turbine und entsprechenden Leitungen wieder zur Staubsaugerdüse geleitet. Dort tritt diese zurückgeleitete Luft aus einem vor dem Saugkanal liegenden Blasschlitz wieder aus. Die Luft wird bei diesem Staubsauger im Kreis geführt. Weiterhin ist bekannt, daß die zurückgeführte Luft mit einer geeigneten Heizvorrichtung erhitzt werden kann, so daß die erhitzte Luft, die aus dem vor dem Saugkanal liegenden Blasschlitz austritt, das Teppichgewebe oder jede andere textile zu reinigende Oberfläche auflockert sowie deren Textur erweitert. Die Heizvorrichtung zum Aufheizen der Saugluft ist dabei nicht in der Staubsaugerdüse, sondern im eigentlichen Staubsaugergehaüse mit angeordnet. Die Temperaturen der erhitzten Luft liegen bei dieser Staubsaugerdüse offensichtlich nicht sehr hoch, da die erhitzte Luft den gesamten Weg vom eigentlichen Staubsauger bis zur Staubsaugerdüse transportiert werden muß und sich auf diesem Weg offensichtlich ziemlich abkühlt.From FR-A-2 601 239 a vacuum cleaner is known which is equipped with a nozzle which is equipped with a suction channel and a blow slot in front of it. The air sucked in through the suction channel and the associated suction pipe is led to the suction motor, filtered there and conducted back to the vacuum cleaner nozzle with the help of a turbine and corresponding lines. There, this returned air emerges from a blow slot located in front of the suction channel. The air is circulated in this vacuum cleaner. It is also known that the recirculated air can be heated with a suitable heating device, so that the heated air, which emerges from the blow slot located in front of the suction channel, loosens the carpet fabric or any other textile surface to be cleaned and expands its texture. The heating device for heating the suction air is not arranged in the vacuum cleaner nozzle, but in the actual vacuum cleaner housing. The temperatures of the heated air are obviously not very high with this vacuum cleaner nozzle, since the heated air has to be transported all the way from the actual vacuum cleaner to the vacuum cleaner nozzle and obviously cools down quite a bit in this way.

Aus der US-A-4 315 344 ist eine Staubsaugerdüse bekannt, die mit einem in der Staubsaugerdüse angeordneten Gebläse ausgestattet ist. Dieses Gebläse ist in der Düse dem Saugkanal gegenüberliegend angeordnet und dient der Verstärkung des Saugluftstromes in den einzelnen Saugkanälen, die entlang der Düsenunterseite verlaufen und die Funktion haben, den Saugstrom zu vergrößern und größere Schmutz- und Staubteilchen in Richtung Saugdüseneingang zu schieben. Dieses bekannte in der Saugdüse angeordnete Gebläse ist lediglich ein Kaltluft-, kein Heißluftgebläse.From US-A-4 315 344 a vacuum cleaner nozzle is known which is equipped with a blower arranged in the vacuum cleaner nozzle. This fan is arranged in the nozzle opposite the suction channel and serves to amplify the suction air flow in the individual suction channels that run along the The underside of the nozzle runs and has the function of increasing the suction flow and pushing larger dirt and dust particles towards the inlet of the suction nozzle. This known blower arranged in the suction nozzle is only a cold air blower, not a hot air blower.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Bekämpfung der Hausstaubmilbe zu schaffen, welches umweltfreundlich, ohne chemische Zusätze arbeitet und in einem Arbeitsgang die Milben aus ihrer Verklammerung mit den textilen Fasern löst und abschließend Hausstaubmilben und deren Exkremente absaugt.The invention has for its object to provide a method and a device for combating the house dust mite, which works in an environmentally friendly manner, without chemical additives and in one operation releases the mites from their clinging with the textile fibers and finally sucks house dust mites and their excrement.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die zu behandelnde Stelle mit Hilfe einer an sich bekannten Staubsaugerdüse, die mit einer Heißluftquelle zusammenwirkt, kurzzeitig mit Heißluft einer Temperatur von 60 °C bis 70 °C beaufschlagt wird und anschließend nach kurzzeitigem Einwirken der Heißluft abgesaugt wird.This object is achieved in that the area to be treated is briefly pressurized with hot air at a temperature of 60 ° C to 70 ° C with the help of a known vacuum cleaner nozzle, which cooperates with a hot air source, and then suctioned off after a brief exposure to the hot air .

Die Vorrichtung zur Durchführung dieses Verfahrens ist gekennzeichnet durch eine aus Oberteil und Unterteil bestehende Staubsaugerdüse, die über ein Gelenk und einen Drehgelenkstutzen an einem Saugrohr angebracht sind, wobei die Staubsaugerdüse selbst ein Heißluftgebläse trägt und wobei im Unterteil ein Saugkanal verläuft, vor dem ein Blasschlitz angeordnet ist, aus dem auf mindestens 60 °C bis 70 °C erhitzte Heißluft 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 are attached to a suction pipe via a joint and a swivel joint, the vacuum cleaner nozzle itself carrying a hot-air blower and with a suction channel running in the lower part, in front of which a blow slot is arranged from which hot air heated to at least 60 ° C to 70 ° C flows onto the surface to be cleaned.

Vorteilhafte Weiterbildungen ergeben sich aus den Merkmalen des Anspruchs 3.Advantageous further developments result from the features of claim 3.

Nachstehend 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, for example, with reference to the schematic drawing; 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 an upper part (1) and a 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 to 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. 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 supplied with power by a mains cable (9); it can, however, 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 means of 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 works 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.
