Description
LuftfilterAir filter
Die Neuerung betrifft einen Luftfilter, insbesondere für die Reinigung der Frischluft für eine Kraftfahrzeugkabine, nach der Gattung des Schutzanspruches 1. Derartige Luftfilter sind bekannt, und werden z.B. in die Klimaanlagen von Fahrzeugen eingebaut. Es ist weiterhin z.B. aus der US 52 03 989 bekannt, das aus der Luft abgeschiedene Wasser mit Hilfe von UV-Licht von Keimen zu befreien, um es weiter verwenden zu können.The innovation relates to an air filter, in particular for cleaning the fresh air for a motor vehicle cabin, according to the class of protection claim 1. Such air filters are known and are installed, for example, in the air conditioning systems of vehicles. It is also known, for example from US 52 03 989, to remove germs from the water separated from the air using UV light in order to be able to use it further.
Allerdings wird bei der Innenraumluftfilterung auch die gefilterte Luft benötigt, welche durch Keime die im Innenraum befindlichen Personen belasten kann. Allerdings lassen sich gasförmige Medien aufgrund ihrer Durchströmungsgeschwindigkeit nicht ohne weiteres mit UV-Strahlung behandeln. Die kurze Verweilzeit des Mediums würde nicht ausreichen, um die Keime zuverlässig abzutöten.However, interior air filtration also requires filtered air, which can contaminate people inside the building with germs. However, gaseous media cannot be easily treated with UV radiation due to the speed at which they flow. The short residence time of the medium would not be sufficient to reliably kill the germs.
Daher ist es Aufgabe der Neuerung, einen Filter zu schaffen, der die Zuführung von keimfreier Luft in einen Innenraum ermöglicht. Diese Aufgabe wird durch die Merkmale des Schutzanspruches 1 gelöst.Therefore, the aim of the innovation is to create a filter that enables the supply of germ-free air into an interior space. This task is solved by the features of claim 1.
Der Luftfilter gemäß der Neuerung ist in bekannter Weise aufgebaut und dadurch gekennzeichnet, daß Mittel zur Erzeugung von UV-Strahlung derart im Gehäuse angebracht sind, daß sie das Filterelement, welches in das Gehäuse integriert ist bestrahlt. Das Mittel zur Erzeugung von UV-Strahlung ist insbesondere eine UV-Leuchtröhre. Es hat sich nämlich gezeigt, daß die Kontamination der Innenraumluft mit Keimen vorrangig durch das Filterelement selbst entsteht. Dieses ist bei den Standzeiten des Pkw ein geeigneter Brutplatz für Mikroorganismen, insbesondere dann, wenn das Filterelement feucht geworden ist. Bei einer Inbetriebnahme desThe air filter according to the innovation is constructed in a known manner and is characterized in that means for generating UV radiation are mounted in the housing in such a way that they irradiate the filter element, which is integrated into the housing. The means for generating UV radiation is in particular a UV fluorescent tube. It has been shown that the contamination of the interior air with germs is primarily caused by the filter element itself. This is a suitable breeding ground for microorganisms when the car is not in use, especially when the filter element has become damp. When the

Fahrzeugs nach längeren Stillstandszeiten wandern die Keime aus dem Filterelement in die gefilterte Innenraumluft. Daher ist es von großem Vorteil, die Keime spätestens zum Zeitpunkt der Inbetriebnahme des Fahrzeugs am Entstehungsort abzutöten. Eine negative Auswirkung auf die Gesundheit der Fahrzeuginsassen wird somit vermieden.After a long period of downtime, the germs from the filter element migrate into the filtered interior air. It is therefore a great advantage to kill the germs at the point of origin at the latest when the vehicle is put into operation. This avoids any negative impact on the health of the vehicle's occupants.
Nach einer Ausgestaltung der Neuerung ist eine Steuerung vorgesehen, die die Einschaltzeiten der Mittel zur Erzeugung von UV-Strahlung bestimmt. Hierbei können verschiedene Parameter ausgewertet werden. Die Einschaltung der UV-Röhre ist z.B. nach längeren Stillstandszeiten, bei Feuchtwerden des Filterelements oder in bestimmten Abständen während des Betriebs sinnvoll.According to one design of the innovation, a control system is provided that determines the switching-on times of the means for generating UV radiation. Various parameters can be evaluated here. Switching on the UV tube is useful, for example, after longer periods of downtime, when the filter element becomes damp or at certain intervals during operation.
Das einfachste Verfahren zur Ansteuerung des UV-Strahlers macht ein Einschalten von der Länge der verstrichenen Zeit seit der letzten Nutzung des Fahrzeugs abhängig. Hintergrund hierfür ist die Überlegung, daß bei Stillstand des Fahrzeuges der Innenraumluftfilter über längere Zeit nicht von Luft durchströmt wird, was insbesondere, wenn dieser feucht ist, die Vermehrung von Mikroorganismen im Filtermedium begünstigt. Nur für diesen Fall wird das Filtermedium durch den UV-Strahler desinfiziert. Auf diese Weise läßt sich die Standzeit des UV-Strahlers zur Behandlung des Filtermediums verlängern. Es ist auch möglich, eine UV-Strahlung immer nur im Stillstand des Fahrzeuges durchzuführen, so daß der aktivierte UV-Strahler, insbesondere die Leuchtstoffröhre, nicht durch Erschütterungen beschädigt werden kann.The simplest method for controlling the UV lamp is to switch it on depending on the length of time that has passed since the last time the vehicle was used. The reason for this is that when the vehicle is stationary, the interior air filter is not passed through by air for a long time, which encourages the proliferation of microorganisms in the filter medium, especially when it is damp. The filter medium is only disinfected by the UV lamp in this case. In this way, the service life of the UV lamp for treating the filter medium can be extended. It is also possible to only use UV radiation when the vehicle is stationary, so that the activated UV lamp, in particular the fluorescent tube, cannot be damaged by vibrations.
Die einzige Figur zeigt den schematischen Aufbau eines Luftfiltergehäuses 10 mit einem Einlaß 14 und einem Auslaß 15. Die Durchströmung der Luft ist durch Pfeile angedeutet. Ein Luftfilter 11 ist in einer Trennfuge 18 des Gehäuses dichtend eingebaut. Auf der Reinseite des Filterelementes befindet sich eine Leuchtröhre 12 für UV-Strahlung, die an einer Spannungsquelle 16 angeschlossen ist. Über eine Steuerung 13 wird ein Schalter 17 betätigt, der zur Einschaltung der Leuchtröhre 12 gedacht ist. Die Steuerung 13 kann auch weitere Signale, z.B. aus der Motorsteuerung empfangen. The only figure shows the schematic structure of an air filter housing 10 with an inlet 14 and an outlet 15. The flow of air is indicated by arrows. An air filter 11 is installed in a sealing manner in a joint 18 of the housing. On the clean side of the filter element there is a fluorescent tube 12 for UV radiation, which is connected to a voltage source 16. A switch 17 is operated via a control 13, which is intended to switch on the fluorescent tube 12. The control 13 can also receive other signals, e.g. from the engine control.
