Description

Das Hauptpatent schützt ein Verfahren zum Nachweis der Fettsättigung von Filtermaterial, insbesondere für Dunstabzughauben, sowie einen entsprechenden Fettfilter, insbesondere für Dunstabzughauben, mit einer auf der nicht sichtbaren oder Rückseite des Filtermaterials aufgebrachten fett- und/oder öllöslichen farbgebenden Substanz, die bei Sättigung des Filters auf der Vorderseite eine Farbänderung bewirkt.The main patent protects a method for detecting the fat saturation of filter material, especially for extractor hoods, as well as a corresponding grease filter, especially for extractor hoods, with a fat- and / or oil-soluble coloring substance that is applied to the invisible or reverse side of the filter material, which when the filter is saturated causes a color change on the front.

Die Erfindung betrifft eine Weiterbildung des Fettfilters nach dem Hauptpatent und besteht in einer weiteren Geruchsstoffe aufnehmenden oder chemisch bindenden Substanz. The invention relates to a further development of the grease filter according to the main patent and consists of a further odor absorbing or chemically binding substance.

Fett filter werden bei Dunstabzughauben in Haushaltungen eingesetzt, die im Umluft- oder im Abluftbetrieb arbeiten. Insbesondere, wenn ein Abluftbetrieb nicht möglich ist, d.h. wenn im Umluftbetrieb gearbeitet wird, ist es erforderlich, zusätzlich zu der Fettfiltermatte eine Einrichtung vorzusehen, die diejenigen Stoffe, insbesondere die Geruchsstoffe aufnimmt, die nicht von dem Fettfilter gebunden werden. Es ist bekannt, größere Kunststoffkapseln in einem größeren Abstand anschließend an die Fettfiltermatte vorzusehen, wobei die Kunststoffkapseln Aktivkohle oder andere Chemikalien zur Neutralisation der Luft enthalten. Diese, einen verhältnismäßig großen Raum beanspruchenden Kunststoffkapseln müssen normalerweise in einem größeren Zeitabstand ausgewechselt werden als die B'ettfiltermatte. Bei normalem Betrieb muß die Fettfiltermatte ungefähr alle drei Monate ausgewechselt werden, wohingegen die teuren Kunststoffkapseln erst nach Verstreichen eines längeren Zeitraums ausgewechselt werden müssen, die Standzeit aber ebenso nur einen kürzeren Zeitraum zuläßt.Grease filters are used in kitchen range hoods, that work in recirculation or exhaust air mode. In particular if exhaust air operation is not possible, i.e. If you are working in recirculation mode, it is necessary to provide a device in addition to the grease filter mat, which absorbs those substances, especially the odorous substances, which are not bound by the grease filter. It it is known to provide larger plastic capsules at a greater distance next to the grease filter mat, wherein the plastic capsules contain activated charcoal or other chemicals to neutralize the air. This one, proportionately Plastic capsules that take up a lot of space usually have to be replaced at longer intervals are called the bed filter mat. During normal operation, the grease filter mat must be replaced approximately every three months. whereas the expensive plastic capsules only after lapse have to be replaced over a longer period of time, but the service life also only allows a shorter period of time.

Die Erfindung löst nun die Aufgäbe,bei einem Fettfilter nach dem Hauptpatent nicht nur die Fette herauszufiltern, sondern The invention now solves the task of not only filtering out the fats in a grease filter according to the main patent , but also

909851/0358909851/0358

auch mit ein und demselben Gegenstand für eine Reinigung und Neutralisation der Luft, d.h. zum Entfernen der Geruchsstoffe, zu sorgen, wobei dieses insbesondere im Umluftverfahren von Vorteil ist und hier bei regelmäßigem Filterwechsel der Wirkungegrad der Haube durch Synchronisierung des Fettfilters mit dem Geruchsfilter wesentlich verbessert wird.with one and the same object for a cleaning and neutralization of the air, ie, to remove the odorous substances to ensure, this being in particular in the air circulation process of advantage and here at regular filter change of Wirkungegrad the hood is substantially improved by synchronizing the grease filter with the odor filter .

Als die Geruchsstoffe aufnehmende oder chemisch bindende Substanzen kommen Aktivkohle, Kieselgur und andere Chemikalien infrage, zu denen beispielsweise Polyacryl und Metaacrylsäure gehören. In vorteilhafter Weise wird die Granulat- oder Pulverform gewählt.As substances absorbing or chemically binding odorous substances Activated carbon, kieselguhr and other chemicals are possible, including polyacrylic and metaacrylic acid. In the granulate or powder form is advantageously chosen.

Es ist entweder möglich, diese weiter(en) Substanz(en) in die Fettfiltermatte, die beispielsweise aus einem Vliesmaterial besteht j einzubeziehen oder aber eine gesonderte Matte aus Vliesmaterial oder dergl. auszubilden und diese auf der Rückseite der Fettfiltermatte anzuordnen.It is either possible to add this substance (s) to the grease filter mat, which is made, for example, of a fleece material consists of including j or a separate mat made of non-woven material Or the like. And to arrange them on the back of the grease filter mat.

Die Zusammensetzung und die Eigenschaften der zusätzlichen Substanz wird so ausgewählt, daß die Aufgabe, die diesen Substanzen zugedacht ist, so lange sicher erfüllt wird, wie die Fettfiltermatte das Fett herausfiltert. Wenn die Fettfiltermatte verbraucht ist und ausgewechselt werden muß - dieses wird durch die farbgebende Substanz angezeigt - so erfolgt ein Auswechseln der gesamten Fettfiltermatte, d.h. also auch ein Auswechseln der weiteren, die Geruchsstoffe aufnehmenden oder chemisch bindenden Substanz.The composition and the properties of the additional substance are selected so that the task that these substances are intended to be reliably fulfilled as long as the grease filter mat filters out the grease. If the grease filter mat is used up and needs to be replaced - this is indicated by the coloring substance - as a replacement takes place throughout the grease filter mat, so that is also an exchange of the other, the odorous substances absorbing or chemically binding substance.

Durch die Kombination nach der Erfindung können die Abzughauben flacher und kleiner gebaut werden, so daß hier nicht nur ein häufig sehr knapper Raum, sondern auch Ma.terial gespart wird. Due to the combination according to the invention, the extractor hoods can be made flatter and smaller , so that not only an often very tight space, but also material is saved here.

Weitere Vorteile und Einzelheiten der Erfindung werden im folgenden unter Hinweis auf die Zeichnung anhand eines Ausfüh rungsbeispieles näher erläutert. Further advantages and details of the invention are explained in more detail below with reference to the drawing using an Ausfüh approximately example.

In der einzigen Figur ist eine Ausführungsform eines Piltermaterxales nach der Erfindung schematisch im Schnitt dargestellt, wobei die weitere, die Geruchsstoffe aufnehmende Substanz in einer gesonderten Matte vorgesehen ist.In the single figure, one embodiment is one Piltermaterxales according to the invention shown schematically in section, with the further substance absorbing the odorous substances in a separate mat is provided.

Der veranschaulicht Fettfilter besteht aus einer Fettfiltermatte 1, auf deren Rückseite eine sog. Carbonmatte 2 vorgesehen ist, die ein Aktivkohlegranulat bei dieser Ausführungsform enthält. Auf der Rückseite der Fettfiltermatte 1 ist ein Auftrag 3 aufgedruckt, der die fett- und/oder öllösliche und farbgebende Substanz umfaßt, deren Farbe von derjenigen des Fettfiltermaterials abweicht und bei einer bestimmten Sättigung auf der Vorderseite sichtbar wird.The grease filter illustrated consists of a grease filter mat 1, on the rear side of which a so-called carbon mat 2 is provided which contains an activated carbon granulate in this embodiment. An order 3 is printed on the back of the grease filter mat 1, which specifies the grease and / or oil-soluble and coloring substance comprises, their Color differs from that of the grease filter material and is visible on the front at a certain level of saturation will.

Anstelle von Aktivkohle können andere Substanzen oder Kombinationen mit Aktivkohle eingesetzt werden.Instead of activated carbon, other substances or combinations with activated carbon can be used.
