Abstract
Description
Die Erfindung bezieht sich auf eine Abzugshaube nach dem Oberbegriff des Anspruches 1.The invention relates to a fume hood according to the preamble of claim 1.
Aus lufttechnischen- bzw. Energiespargründen werden immer häufiger Abzugshauben verwendet, bei denen die abgesogene Abluft aus dem Kochfeld in einem Umluftbetrieb wieder zurück in den Wohnraum geführt wird, was auch einfacher zu realisieren ist. Bislang wurde besonders in den kalten Jahreszeiten aufgeheizte Luft aus dem Wohnraum abgesaugt und diese dann nach aussen weggeblasen.For technical ventilation or energy saving reasons hoods are increasingly used in which the sucked exhaust air from the hob is performed in a recirculation mode back to the living room, which is also easier to implement. So far, especially in the cold seasons heated air was sucked out of the living room and then blown away to the outside.
Bei einer Einrichtung im Abluftkanal einer Abzugshaube gemäss der Druckschrift
Der vorliegenden Erfindung liegt demgegenüber die Aufgabe zugrunde, eine Abzugshaube zu schaffen, mittels welcher die vom Kochen abgesaugte und durch den Umluftbetrieb wieder in den Wohnraum zurückgeleitete Abluft nahezu vollständig, auch hinsichtlich Geschmackrückstände gereinigt wird.The present invention is the object of the invention to provide a fume hood, by means of which the sucked off by cooking and returned by the recirculation mode back into the living room exhaust air is almost completely cleaned, even with respect to taste residues.
Die Aufgabe ist erfindungsgemäss durch eine Abzugshaube nach den Merkmalen des Anspruchs 1 gelöst.The object is achieved by a hood according to the features of claim 1.
Bei der erfindungsgemässen Abzugshaube besteht der wenigstens eine im Haubenteil integrierte Filter und/oder ein zusätzlicher Filter aus einem solchen Material, dass mit ihm die in der Abluft enthaltenden Fettpartikel annähernd vollständig filtriert werden.In the extractor hood according to the invention, the at least one filter integrated in the hood part and / or an additional filter consists of such a material that it almost completely filters the fat particles contained in the exhaust air.
Mit einer solchen Abzugshaube ergibt sich ein verbesserter Komfort im Wohnbereich während und nach dem Kochen mit Umluftbetrieb, insbesondere wenn fettreich gekocht bzw. gebraten wird. Zudem kann mit dieser Abzugshaube im Prinzip auf eine Abluftleitung nach aussen verzichtet werden und damit ein weiterer Vorteil entsteht, nämlich dass wenn die Abzugshaube nicht in Betrieb ist, keine kalte Luft durch diese Abluftleitungen ins Innere des Hauses dringt.With such a hood results in improved comfort in the living area during and after cooking with recirculation mode, especially when cooked rich or fried. In addition, with this Extractor hood in principle be dispensed with an exhaust pipe to the outside and thus another advantage arises, namely that when the hood is not in operation, no cold air penetrates through these exhaust ducts into the interior of the house.
Weitere vorteilhafte Einzelheiten der Abzugshaube im Rahmen der Erfindung sind in den abhängigen Ansprüchen definiert.Further advantageous details of the hood in the context of the invention are defined in the dependent claims.

In dem unten mit einer Öffnung 16 für das Ansaugen der Abluft versehenen Haubenteil 15 sind drei nebeneinander angeordnete plattenförmige Abluftfilter 17 aufgenommen, welche in herkömmlicher Weise jeweils in den Haubenteil 15 einlegbar und aber auch leicht aus diesem entfernbar sind, so dass sie beispielsweise in einem Geschirrspüler gereinigt und wieder eingesetzt werden können. Zweckmässigerweise sind diese Abluftfilter 17 aus mehrschichtigen Metallnetzen hergestellt, so dass sie über eine mehrjährige Lebensdauer verfügen. Bei kleineren Abzugshauben könnte selbstverständlich auch nur einer oder zwei solcher Abluftfilter 17 vorhanden sein. Es könnten aber auch mehr als drei eingesetzt sein.In the below provided with an
Im Kanalgehäuse 12 sind ausserdem an sich bekannte Geruchsfilter, zum Beispiel kassettenförmige Aktivkohlenfilter 18, 19 auswechselbar eingebaut, mittels welchen zum einen eine deutliche Geräuschverminderung eines Motors 23 für den Verttilator und zum andern eine Geruchsreduktion erzielt wird. Solche Geruchsfilter könnten auch in den Auslassöffnungen 14' platziert sein.In channel housing 12 are also known per se odor filter, for example cassette-shaped activated
Die als Aerosol erzeugte Abluft, die sich aus einem Gemisch aus Luft, Gasen, Wasserdampf, Fettpartikeln und anderen flüssigen bzw. festen Schwebeteilchen zusammensetzt, werden diese Gase bzw. Partikel mit solchen Filtern 17, 18, 19 nicht vollständig gefiltert, sondern es sind insbesondere Fettpartikel und auch Geruchsrückstände, die bei einem Umluftbetrieb in den Wohnraum zurückgeführt werden.The exhaust air generated as an aerosol, which is composed of a mixture of air, gases, water vapor, fat particles and other liquid or solid suspended particles, these gases or particles with
Erfindungsgemäss sind im Haubenteil 15 oberhalb der Abluftfilter 17 zusätzliche Filter 20 integriert, welche aus einem solchen Material bestehen, dass mit ihnen die in der Abluft enthaltenden Fettpartikel annähernd vollständig filtriert werden.According to the
Mit diesem erfindungsgemässen Filter 20 sollen massenmässig vorteilhaft mehr als 95% der in der Abluft befindlichen Fettpartikel filtriert werden. Damit wird eine normgemässe Filtrierung realisiert.With this

Die Erfindung ist mit den obigen Ausführungsbeispielen ausreichend dargetan. Sie könnte aber noch durch andere Varianten veranschaulicht sein. So könnten beispielsweise diese als Einwegfilter ausgebildeten Filter 20, 30, 40 zusätzlich oder nur anströmseitig angeordnet und beispielsweise mit einem Stabilisationsgeflecht bzw. -stäben gehalten sein.The invention is sufficiently demonstrated with the above embodiments. But it could still be illustrated by other variants. Thus, for example, these
Es könnte auch eine Abzugshaube vorgesehen sein, welche nur mit Umluftbetrieb arbeitet.It could also be provided with a hood, which works only with recirculation mode.
Bei diesen Einwegfiltern werden vorteilhaft rezyklierbare Materialien verwendet. Zudem könnten diese vom Benutzer als Rolle gekauft und auf Mass zugeschnitten und in den jeweiligen Rahmen 30', 40', 50' eingelegt werden. Es könnten je nach Bedarf auch zwei oder mehrere übereinander gelegte Einwegfilter vorgesehen sein.These disposable filters advantageously use recyclable materials. In addition, these could be purchased by the user as a roll and cut to size and placed in the respective frame 30 ', 40', 50 '. It could be provided as needed, two or more superimposed disposable filter.
