Description

Filter für Luftaufbereitungsgeräte Filters for air treatment devices

Die Erfindung betrifft einen Filter zur Reinigung und Aufbereitung von Luft, z.B. für Klimaanlagen, Luftverbesserer und Küchendunstfiltergeräte, mit einem elektrischen Strahler.The invention relates to a filter for cleaning and processing of air, e.g. for air conditioning systems, air fresheners and kitchen vapor filter devices with an electric emitter.

Bei einem bekannten Gerät zur Aufbereitung von Küchendunsthaltiger Luft (D3GN 1902 183) wird zwecks Desodorierung der Küchendünste mittels eines Ultraviolett-Strahlers Ozon erzeugt, das anschließend von einem Katalysator in 2-atomigen Sauerstoff umgewandelt wird.In a known device for processing kitchen vapors Air (D3GN 1902 183) is used to deodorize kitchen vapors by means of an ultraviolet emitter Ozone is generated, which is then converted into 2-atom oxygen by a catalyst will.

Nachteilig ist bei diesem Gerät - außer dem Wartungsaufwand des Katalysators - daß die bakterizide Wirkung des Strahlers einerseits und die Umwandlung des Ozons in 2-atomigen Sauerstoff andererseits nicht gleichzeitig und nicht in einem einzigen und nach außen hin abgegrenzten Raum, sondern zeitlich und räumlich voneinander getrennt stattfinden. Damit ist nicht mit Sicherheit gewährleistet, daß kein Ozon mit der aufbereiteten Luft in den Küchenraum gelangen kann.The disadvantage of this device - apart from the maintenance effort of the catalytic converter - That the bactericidal effect of the radiator on the one hand and the conversion of the ozone in 2-atom oxygen, on the other hand, not simultaneously and not in a single one and outwardly delimited space, but temporally and spatially from each other take place separately. This does not guarantee with certainty that there is no ozone can get into the kitchen with the treated air.

Die Gefahr der toxischen Wirkung des in den Küchenraum gelangenden Ozons ist bei diesem Gerät daher nicht vollständig ausgeschlossen.The risk of toxic effects from entering the kitchen area Ozone is therefore not completely excluded with this device.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Filter der eingangs bezeichneten Gattung mit einfachen Mitteln zu schaffen, der die Geruchsstoffe durch Oxydation beseitigt, Bakterien und Pilzwachstum verhindert und gleichzeitig mit Sicherheit gewährleistet, daß kein Ozon in den Küchenraum gelangen kann.The invention is therefore based on the object of a filter of the initially designated genus to create with simple means that the odorous substances through Eliminates oxidation, prevents bacteria and fungal growth and at the same time with Safety ensures that no ozone can get into the kitchen area.

Erfindungsgemäß wird diese Aufgabe gelöst durch einen mit elektrischen Anschlußorganen versehenen, luftdurchlässigen Reaktionsbehälter, in dem mindestens eine Schicht eines Filtermediums sowie eine mit den elektrischen Anschlußorganen verbundene. Quecksilber-Niederdrucklampe angeordnet sind, wobei letztere mit einem im Behälter angeordneten Vorschaltaggregat elektrisch verbunden ist.According to the invention, this object is achieved by an electrical Connection organs provided, air-permeable reaction container in which at least a layer of a filter medium and one with the electrical connection elements connected. Mercury low pressure lamp are arranged, the latter with a arranged in the container ballast is electrically connected.

Nachfolgend ist ein Ausführungsbeispiel des Erfindungsgegenstandes sowie dessen Vorteile anhand beiliegender Zeichnung näher beschrieben. Es zeigen: Fig. 1 eine Schnittansicht des Filters; Fig. 2 den in ein Luftaufbereitungsgerät eingebauten Filter gem. Fig. 1.The following is an exemplary embodiment of the subject matter of the invention and its advantages are described in more detail with reference to the accompanying drawing. Show it: Fig. 1 is a sectional view of the filter; Fig. 2 in an air treatment device built-in filter according to Fig. 1.

Gemäß Fig. 1 besteht der Filter aus einem Reaktionsbehälter 50, der von einem Rahmen 5 sowie zwei mit diesem verbundenen luftdurchlässigen Filtermatten 3 und 7 gebildet ist. Zwischen der einen Filtermatte 7 und einer weiteren, inneren, ebenfalls luftdurchlässigen Filtermatte 4 befindet sich eine Schicht 6 eines Filtermediums, das aus Aktivkohle, Metallspänen oder anderen adsorbierenden, absorbierenden, oxydierenden und reduzierenden Verbindungen bestehen kann. Die Filtermatte 7 soll ein Austreten von Partikeln des Filtermediums 6 nach außen in die Raumluft verhindern.According to Fig. 1, the filter consists of a reaction vessel 50, the of a frame 5 and two air-permeable filter mats connected to this 3 and 7 is formed. Between the one filter mat 7 and another, inner, also air-permeable filter mat 4 is a layer 6 of a filter medium, that of activated carbon, metal chips or other adsorbing, absorbing, oxidizing and reducing compounds may exist. The filter mat 7 should leak out Prevent particles of the filter medium 6 from escaping into the room air.

Im Reaktionsbehälter 50 ist eine Quecksilber-Niederdrucklampe 2 sowie ein mit dieser elektrisch verbundenes Vorschaltaggregat 1 angeordnet. Beide sind an elektrische Verbindungsorgane 8 angeschlossen. Das Vorschaltaggregat kann induktiv oder kapazitiv oder ohmlch sein. Die Strömungsrichtung der aufzubereitenden Luft wird durch den Pfeil 9 angezeigt.In the reaction vessel 50 is a low pressure mercury lamp 2 as well a ballast unit 1 electrically connected to this is arranged. Both are connected to electrical connecting members 8. The ballast can be inductive or capacitive or ohmic. The direction of flow of the air to be treated is indicated by arrow 9.

Die Funktion des in ein Luftaufbereitungsgerät gemäß Fig. 2 eingebauten Filters ist folgende: Die Küchendünste (Pfeile 15) werden vom Gebläse 20 angesaugt und durchströmen zuerst ein Fettfilter 30, das Fettpartikel und Schwebeteilchen weitgehend absorbiert.The function of the built into an air treatment device according to FIG Filters is as follows: The kitchen vapors (arrows 15) are sucked in by the fan 20 and first pass through a grease filter 30, the grease particles and suspended particles largely absorbed.

Danach tritt die vom Gebläse 20 geförderte Luft 40 in den Reaktionsbehälter 50 ein und wird in diesem von der Quecksilber-Niederdrucklampe 2 bestrahlt. Durch diese Bestrahlung (Wellenlänge 254 nm) werden Bakterien Pilze und Viren vernichtet. Das hierbei entstehende Ozon (Wellenlänge < 200nm) zerfällt jedoch sofort unter Bildung von naszierendem Sauerstoff. Bei Abwesenheit von Geruchsstoffen vereinigt sich der naszierende Sauerstoff mit Nachbaratomen zu Sauerstoff (02). . Bei Anwesenheit von Geruchsstoffen jedoch verbindet sich der äußerst reaktionsfreudige naszierende Sauerstoff mit diesen Geruchsstoffen unter Bildung Geruchs-neutraler Stoffe.Thereafter, the air 40 conveyed by the fan 20 enters the reaction container 50 and is irradiated in this by the low-pressure mercury lamp 2. By this radiation (wavelength 254 nm) destroys bacteria, fungi and viruses. The resulting ozone (wavelength <200nm) decays immediately Formation of nascent oxygen. Combined in the absence of odorous substances the nascent oxygen with neighboring atoms to oxygen (02). . When present of odorous substances, however, combines the extremely reactive nascent Oxygen with these odorous substances with the formation of odor-neutral substances.

Der überschüssige naszierende Sauerstoff dringt in das Filtermedium 6 ein und leitet auch in diesem die oben beschriebene Reaktion ein. Nur gereinigte Luft kann somit das Filter verlassen. Die vom Vorschaltaggregat 1 erzeugte Wärmemenge beschleunigt noch die oben beschriebenen chemischen Reaktionen.The excess nascent oxygen penetrates the filter medium 6 and also initiates the reaction described above in this. Only cleaned Air can therefore leave the filter. The amount of heat generated by the ballast unit 1 accelerates the chemical reactions described above.

Zur Funktionsanzeige dient ein am Rahmen 5 angebrachtes Kontrollfenster 10, das durchsichtig, jedoch für kurzwellige UV-Strahlung undurchlässig ist. Zu gleichem Zweck kann jedoch auch eine Kontrollampe dienen.A control window attached to the frame 5 serves to display the function 10, which is transparent but impermeable to short-wave UV radiation. to However, a control lamp can also serve the same purpose.

Das Einbaufilter kann in einer Dunstabzugshaube sowohl auf der Saugseite, als auch auf der Druckseite des Gebläses 20 angeordnet werden. In jedem Fall wird die Strömungsrichtung der Luft (vgl. Pfeil 9) beibehalten.The built-in filter can be installed in an extractor hood on the suction side, as well as on the pressure side of the fan 20 are arranged. In any case it will maintain the direction of flow of the air (see arrow 9).
