Die in den Zeichnungen dargestellte Dunstabzugsvorrichtung für Küchen enthält eine Unterbau-Dunstabzugshaube 2 und eine Geruchsfilterkassette 4.The kitchen extractor hood shown in the drawings includes one Undermount extractor hood 2 and an odor filter cassette 4.

Die Dunstabzugshaube 2 kann wahlweise entweder gemäß Fig. 1 über lange Schrauben 6 und Distanzhülsen 8 unter Freilassung eines Zwischenraumes 10 oder gemäß Fig. 2 unter Vermeidung eines solchen Zwischenraumes 10 direkt an der Unterseite 12 eines Oberschrankes aufgehängt werden. Der Oberschrank 14 ist beispielsweise in einer Küche mit Abstand vom Boden an einer Küchenwand 16 befestigt. Im Oberschrank 14 ist ein vertikaler Durchgang 18 für eine Abluftleitung 20 gebildet.The extractor hood 2 can either be long screws as shown in FIG. 1 6 and spacer sleeves 8 leaving a space 10 or according to 2 avoiding such a space 10 directly on the underside 12 of an upper cabinet. The upper cabinet 14 is in one, for example Kitchen attached to the kitchen wall 16 at a distance from the floor. In the wall unit 14, a vertical passage 18 is formed for an exhaust duct 20.

Bei Verwendung der Dunstabzugshaube 2 ohne die Geruchsfilterkassette 4 gemäß Fig. 2 kann das untere Ende der Abluftleitung 20 in eine Luftauslaß-Anschlußöffnung 22 eingefügt werden, welche in der hinteren Hälfte einer geschlossenen Decke 24 der Dunstabzugshaube 2 gebildet ist. Das obere Ende der Abluftleitung 20 ist an eine Maueröffnung 26 angeschlossen. Dadurch kann die Dunstabzugshaube 2 im sogenannten Abluftbetrieb verwendet werden, wie dies in Fig.2 dargestellt ist. Der Boden 30 der Dunstabzugshaube 2 ist als Gitter, Lochblech, gelochtes Streckmetall oder in anderer Weise luftdurchlässig ausgebildet. Auf dem Boden 30 liegt ein einlagiger oder mehrlagiger Fettfilter 32. Ein in der Dunstabzugshaube 2 angeordnetes Gebläse 34 saugt aus der Küche Luft 36 durch den Fettfilter 32 und treibt sie durch die Abluftleitung 20 und die Maueröffnung 26 aus dem Haus.When using the extractor hood 2 without the odor filter cartridge 4 according to Fig. 2 can the lower end of the exhaust duct 20 into an air outlet port 22 are inserted, which in the rear half of a closed ceiling 24 of the Extractor hood 2 is formed. The upper end of the exhaust line 20 is at one Wall opening 26 connected. This allows the extractor hood 2 in the so-called Exhaust mode can be used, as shown in Fig.2. The floor 30 of the extractor hood 2 is as a grid, perforated plate, perforated expanded metal or in otherwise permeable to air. On the floor 30 is a single layer or multilayer grease filter 32. A fan 34 arranged in the extractor hood 2 sucks air 36 from the kitchen through the grease filter 32 and drives it through the exhaust line 20 and the wall opening 26 from the house.

In Fig.2 ist die Dunstabzugshaube 2 ohne Freilassung eines Zwischenraumes direkt an der Unterseite 12 mit kurzen Schrauben 7 befestigt. Eine Luftleitklappe 38 am vorderen Ende der Dunstabzugshaube kann aus der in Fig.2 dargestellten Betriebsstellung in die in Fig.1 gezeigte Ruhestellung nach hinten geklappt werden, so daß sie dann am Boden 30 anliegt. In Figure 2, the extractor hood 2 is directly on without leaving a space the bottom 12 fastened with short screws 7. An air flap 38 on the front End of the extractor hood can from the operating position shown in Fig.2 in the rest position shown in Fig.1 can be folded back so that they then on Floor 30 abuts.

Wenn keine Maueröffnung 26 vorhanden ist oder der Oberschrank 14 keinen Durchgang 18 für eine Abluftleitung 20 hat, dann kann die gleiche Dunstabzugshaube 2 für Umluftbetrieb verwendet werden, bei welchem die vom Gebläse 34 angesaugte Luft 36 durch die Geruchsfilterkassette 4 in die Küche zurückgeleitet wird, entsprechend Pfeilen 39 in Fig.1. Der Zwischenraum 10 zwischen der Dunstabzugshaube 2 und der Unterseite 12 des Oberschrankes 14 ist so eng, daß die Geruchsfilterkassette 4 von vorne in den Zwischenraum 10 eingeschoben und auf die Dunstabzugshaube 2 gesetzt werden kann, jedoch kein wesentlicher Zwischenraum zwischen Geruchsfilterkassette 4 und der Unterseite 12 des Oberschrankes 14 verbleibt. Durch das Aufsetzen der Geruchsfilterkassette 4 auf die Dunstabzugshaube 2 wird automatisch eine Lufteinlaß-Anschlußöffnung 40, die in einem Boden 42 der Geruchsfilterkassette gebildet ist, auf die Luftauslaß-Anschlußöffnung der Dunstabzugshaube 2 gesetzt und mit dieser automatisch verbunden. Dies hat den Vorteil, daß keine zusätzlichen Anschlußelemente erforderlich sind, und daß die Luftauslaß-Anschlußöffnung 22 automatisch durch die Geruchsfilterkassette 4 gegen die Außenumgebung verschlossen wird. Die Abluft der Dunstabzugshaube 2 strömt jetzt von deren Luftauslaß-Anschlußöffnung 22 über die Lufteinlaß-Anschlußöffnung 40 in die Geruchsfilterkassette 4 und in dieser durch Geruchsfiltermaterial 44 hindurch, beispielsweise Aktivkohle oder ein anderes Material, welches aus der Luft Gerüche herausfiltert durch Absorption, Adsorption oder auf andere chemische Art und Weise. Die von Fett im Fettfilter 32 und von Gerüchen im Geruchsfiltermaterial 44 gereinigte Luft 39 gelangt durch einen Luftauslaß 46 aus der Geruchsfilterkassette 4 in die exteme Geräteumgebung, d.h. in die Küche zurück. Der Luftauslaß 46 ist durch eine Vielzahl von Öffnungen in einem schräg nach vorne unten, in Richtung zum Boden 42 abfallenden vorderen DeckenAbschnitt 48 eines Gehäuses der Geruchsfilterkassette 4 gebildet.If there is no wall opening 26 or the upper cabinet 14 no passage 18 for an exhaust duct 20, then the same extractor hood 2 for Recirculation mode can be used, in which the air sucked in by the fan 34 36 is passed back through the odor filter cassette 4 into the kitchen, accordingly Arrows 39 in Fig.1. The space 10 between the extractor hood 2 and the Bottom 12 of the upper cabinet 14 is so narrow that the odor filter cartridge 4 by inserted into the space 10 at the front and placed on the extractor hood 2 can be, but no significant space between the odor filter cassette 4 and the underside 12 of the upper cabinet 14 remains. By putting on the odor filter cassette 4 on the extractor hood 2 automatically becomes one Air inlet port 40 formed in a bottom 42 of the odor filter cartridge is placed on the air outlet connection opening of the extractor hood 2 and with this automatically connected. This has the advantage that no additional connection elements are required, and that the air outlet port 22 automatically closed by the odor filter cassette 4 against the outside environment becomes. The exhaust air from the extractor hood 2 now flows from its air outlet connection opening 22 into the odor filter cassette via the air inlet connection opening 40 4 and in this through odor filter material 44, for example activated carbon or another material that filters odors out of the air through absorption, Adsorption or other chemical means. That of fat in the fat filter 32 and Air 39 cleaned of odors in the odor filter material 44 passes through an air outlet 46 from the odor filter cassette 4 into the external device environment, i.e. in the Kitchen back. The air outlet 46 is through a plurality of openings in one sloping forward downward, towards the floor 42 sloping front ceiling section 48 of a housing of the odor filter cassette 4 is formed.

Der Boden 30 der Dunstabzugshaube 2 ist über seine gesamte Breite schräg nach vorne oben in Richtung zur Haubendecke 24 ansteigend ausgebildet. Dadurch hat die Dunstabzugshaube über ihre gesamte Breite eine nach vorne flacher werdende Keilform, und auch die Geruchsfilterkassette 4 hat mindestens in ihrem vorderen Drittel eine nach vorne flacher werdende Keilform.The bottom 30 of the extractor hood 2 is inclined over its entire width formed at the top and rising towards the hood ceiling 24. As a result, the Extractor hood across its entire width a wedge shape that becomes flatter towards the front, and also the odor filter cassette 4 has at least in its front third Wedge shape flattening towards the front.

Wie besonders Fig.3 zeigt, ist die Luftaus-Anschlußöffnung 22 der Dunstabzugshaube 2 durch einen in ihre Decke 24 eingebauten Rohrstutzen gebildet, in oder auf welchen wahlweise die Abluftleitung 20 oder die Lufteinlaß-Anschlußöffnung 40 gesetzt werden kann. Letztere kann ebenfalls die Form eines Rohrstutzens haben, welcher in oder auf den Rohrstutzen der Luftauslaß-Anschlußöffnung 22 paßt. Die Figuren 3 und 4 zeigen in der Decke 24 der Dunstabzugshaube 2 gebildete Löcher 50 für die Schrauben 6 von Fig.1 oder Schrauben 7 von Fig.2 zur Aufhängung der Dunstabzugshaube 2 an dem Oberschrank 14.As particularly shown in FIG. 3, the air outlet connection opening 22 is the extractor hood 2 formed by a pipe socket installed in its ceiling 24, in or on which either the exhaust line 20 or the air inlet connection opening 40 can be set can. The latter can also have the shape of a pipe socket, which in or on the pipe socket of the air outlet connection opening 22 fits. Figures 3 and 4 show in the ceiling 24 of the extractor hood 2 holes 50 formed for the screws 6 of Fig.1 or screws 7 of Fig.2 for hanging the extractor hood 2 on the Upper cabinet 14.

Gemäß einer nicht dargestellten anderen Ausführungsform kann die Geruchsfilterkassette 4 in ihrer Decke 52 eine Luftauslaß-Anschlußöffnung haben, welche eine kreisrunde Form entsprechend dem Stutzen 22 hat und an die Abluftleitung 20 anschließbar ist. Dadurch kann die Geruchsfilterkassette 4 zusammen mit der Dunstabzugshaube 2 auch für Abluftbetrieb verwendet werden kann. In diesem Falle gelangt die Abluft nicht in die Küche zurück, sondern durch die Abluftleitung 20 durch die Maueröffnung 26 aus dem Haus. Auch hier hat man den Vorteil, daß die Dunstabzugshaube 2 und die Geruchsfilterkassette 4 sehr flache Baueinheiten sind, welche wahlweise einzeln oder in Kombination verwendet werden können. Jede dieser beiden Baueinheiten 2 und 4 hat im wesentlichen flache, aufeinander passende Oberflächen, welche auch bezüglich ihrer Umfangsränder aneinander angepaßt sind.According to another embodiment, not shown, the odor filter cassette 4 in their ceiling 52 have an air outlet connection opening which is circular Has shape corresponding to the nozzle 22 and connectable to the exhaust duct 20 is. This allows the odor filter cassette 4 together with the extractor hood 2 can also be used for exhaust air operation. In this case, the exhaust air arrives not back to the kitchen, but through the exhaust duct 20 through the wall opening 26 out of the house. Here, too, you have the advantage that the extractor hood 2 and the odor filter cassette 4 are very flat units, which are optionally individually or can be used in combination. Each of these two units 2 and 4 has essentially flat, mating surfaces, which also are adapted to each other with respect to their peripheral edges.
