Eine solche Dunstabzugshauben-Verbindungsvorrichtung ist in der Schrift EP 0 446 136 A beschrieben.Such an extractor hood connection device is described in the document EP 0 446 136 A.

Der Anschluß einer Abluftöffnung einer Dunstabzugshaube an eine Abluftleitung in Form eines Abluftschlauches oder Abluftrohres ist dann schwierig, wenn die Dunstabzugshaube in oder an einen Raum eingebaut wird, welcher von der Dunstabzugshaube verschlossen wird und dadurch anschließend nicht mehr zugänglich ist für das Anschließen der Abluftöffnung der Dunstabzugshaube an die in dem Raum untergebrachte Abluftleitung. Ein solcher geschlossener Raum ist z.B. dann gegeben, wenn die Dunstabzugshaube an oder in einen Raum oder Schacht einer Esse, Holzkamine, Kaminhaube, Verkleidungs-Haube oder Schränke, welche mit Einbauten oder einer Verkleidung, z.B. einem Gewürzbord, versehen sind, angebaut oder eingebaut werden soll.The connection of an exhaust air opening of an extractor hood to an exhaust air line in Form of an exhaust hose or exhaust pipe is difficult if the Extractor hood is installed in or on a room which is separated from the Extractor hood is closed and then no longer is accessible for connecting the extract air opening of the extractor hood to the Exhaust duct housed in the room. Such a closed space is e.g. given when the extractor hood is on or in a room or shaft a chimney, wood fireplaces, chimney hood, cladding hood or cupboards, which with internals or cladding, e.g. a spice rack, to be grown or installed.

Für den Einbau einer Dunstabzugshaube in einen geschlossenen Raum sind zwei Möglichkeiten bekannt. Gemäß der einen Möglichkeit wird ein starres oder steifes Abluftrohr verwendet und mit viel Mühe und Aufwand versucht, den die Abluftöffnung der Dunstabzugshaube bildenden Abluftstutzen in das Abluftrohr einzuführen. Ein Versatz des Abluftrohres muß gegebenenfalls mehrfach korrigiert werden. Eine Kontrolle, ob eine korrekte Verbindung bezüglich Dichtheit und Lage gegeben ist, ist nicht möglich. Gemäß der anderen Möglichkeit wird die Dunstabzugshaube zunächst auf eine Ablage gestellt. Anschließend wird das flexible Abluftrohr oder der flexible Abluftschlauch an dem Abluftstutzen der Dunstabzugshaube befestigt. Zuletzt wird die Dunstabzugshaube in eine Montageöffnung des Raumes eingebaut und die Überlänge der flexiblen Abluftleitung (flexibles Rohr oder Schlauch) in dem Einbau - Raum verstaut. Die flexible Abluftleitung wird dabei in eine unkontrollierbare, beliebige Lage gebracht. Dadurch erhöht sich der Luftwiderstand und das Geräusch der Abluft, und die Abluftleistung wird geringer. Außerdem besteht die Gefahr, daß die Abluftleitung gegen irgendwelche Bauteile vibriert und Geräusche erzeugt.There are two for installing an extractor hood in an enclosed space Possibilities known. According to one possibility, it becomes rigid or rigid Exhaust pipe used and tried with a lot of effort and effort that the Exhaust air opening of the extractor hood forming the extractor hood into the exhaust pipe introduce. An offset of the exhaust pipe may have to be corrected several times become. A check whether a correct connection regarding tightness and position is not possible. According to the other possibility, the Extractor hood first placed on a shelf. Then that will flexible exhaust pipe or the flexible exhaust hose on the exhaust port of the Extractor hood attached. Finally, the extractor hood is turned into one Installation opening of the room built and the excess length of the flexible Exhaust air duct (flexible pipe or hose) stowed in the installation room. The flexible exhaust air duct is brought into an uncontrollable, arbitrary position. This increases the air resistance and the noise of the exhaust air, and that Exhaust air output is reduced. There is also a risk that the exhaust duct vibrates against any component and generates noise.

Durch die Erfindung soll die Aufgabe gelöst werden, die genannten Nachteile zu vermeiden und eine Möglichkeit zu schaffen, durch welche das Anschließen der Dunstabzugshaube an eine Abzugsleitung in einem geschlossenen Raum erleichtert wird und keine unkontrollierbaren Formen und Positionen der Abluftleitung bei der Montage der Dunstabzugshaube entstehen. Damit sollen auch Betriebsgeräusche sowie eine Reduzierung des Luftwiderstandes der Abluftströmung vermieden werden.The object of the invention is to solve the disadvantages mentioned avoid and create a way by which connecting the Extractor hood to an extractor pipe in a closed room is facilitated and no uncontrollable forms and positions of the Exhaust air duct created when installing the extractor hood.
