Description

Die Erfindung bezieht sich auf eine Dunstabzugshaube zur Anordnung über einem Küchenherd od. dgl., vorzugsweise unterhalb oder in Oberschränken von Einbauküchen, mit einem die anfallenden Kochwrasen absaugenden und fördernden Gebläse in einem kastenförmigen Gehäuse mit einer nach vorne hochschwenkbaren Frontplatte, die in ausgeschwenkter Stellung einen über dem Küchenherd ragenden Kochwrasen-Auffangschirm bildet sowie mit einem vor der Ansaugseite des Gebläses angeordneten Filter, der aus einem starren und einem ausschwenkbaren Filterteil gebildet und der ausschwenkbare Filterteil zusammen mit der Frontplatte und einer beweglichen Deckplatte beim Ausschwenken eine Bewegungsfreiheit bildet.The invention relates to an extractor hood for arrangement above a kitchen stove or the like, preferably below or in wall units of built-in kitchens, with a fan that sucks off and promotes the cooking fumes in a box-shaped housing with a front panel that can be swiveled upwards and that in the pivoted-out position forms over the kitchen stove protruding cooktop and with a filter arranged in front of the suction side of the fan, which consists of a rigid and a swing-out filter part and the swing-out filter part together with the front plate and a movable cover plate provides freedom of movement when swiveling out.

Eine Dunstabzugshaube dieser Art ist aus der DE-B-2 206 904 bekannt. Diese Dunstabzugshaube besitzt zwei getrennte Filter, die bei eingeschobenem Haubenteil einander bereichsweise überdeckend angeordnet sind, während sie bei herausgezogenem Haubenteil aneinander anschließen und damit eine vergrößerte Filterfläche ergeben. Der herausziehbare Haubenteil ist hier nach Art einer Schublade ausgebildet und muß somit in seitlichen Schienen od_ dgl. geführt werden. Schienenführungen neigen aber dazu, daß sie schon nach Absetzen von geringsten Schmutzteilchen klemmen und der darin geführte Haubenteil sich nicht mehr leicht bewegen läßt. Da die Dunstabzugshaube außerdem in einer bestimmten Höhe oberhalb des Küchenherdes angeordnet sein muß, bereitet der auf Schienen geführte Haubenteil kleineren Bedienungspersonen oftmals Schwierigkeiten beim Herausziehen, wenn dieser Haubenteil dabei durch leichtes nach unten ziehen in den Führungsschienen verkantet wird.An extractor hood of this type is known from DE-B-2 206 904. This extractor hood has two separate filters which, when the hood part is pushed in, are arranged to overlap one another in regions, while they connect to one another when the hood part is pulled out, thus giving an enlarged filter area. The pull-out hood part is designed here in the manner of a drawer and must therefore be guided in side rails or the like. However, rail guides tend to jam even after the smallest dirt particles have settled and the hood part guided in them can no longer be moved easily. Since the extractor hood must also be arranged at a certain height above the kitchen range, the hood part guided on rails often causes smaller operators difficulties when pulling it out when this hood part is tilted by gently pulling down in the guide rails.

Weiterhin ist eine Dunstabzugshaube aus der DE-A-2 819 096 bekannt. Bei dieser Dunstabzugshaube kann durch nach vorne Aus- und Hochschwenken der Frontplatte ein Kochwrasen-Auffangschirm gebildet werden, der über die Vorderkante des Herdes hinausragt. Damit soll erreicht werden, daß auch von den vorderen Kochstellen des Herdes aufsteigende Wrasen bzw. Kochdünste erfaßt und zum Filtern durch die Dunstabzugshaube geleitet werden. Die effektive Filterfläche bleibt bei dieser Dunstabzugshaube jedoch unverändert, so daß der von den vorderen Kochstellen aufsteigende Wrasenstrom durch die vom Gebläse erzeugte Ansaugegeschwindigkeit von der senkrechten in eine waagerechte Strömungsrichtung umgelenkt werden muß, damit er überhaupt durch den Filter und damit zum Einlaß des Gebläses gelangen kann.Furthermore, an extractor hood is known from DE-A-2 819 096. With this extractor hood, you can create a cooker screen that protrudes beyond the front edge of the cooker by swiveling the front panel out and up. This is to ensure that rising vapors or cooking fumes are also detected from the front hotplates of the cooker and are passed through the extractor hood for filtering. However, the effective filter area remains unchanged with this extractor hood, so that the stream of vapors rising from the front hotplates must be diverted from the vertical into a horizontal direction of flow by the suction speed generated by the fan so that it can get through the filter and thus to the inlet of the fan .

Dadurch wird die Wirksamkeit der Dunstabzugshaube aber erheblich vermindert.This significantly reduces the effectiveness of the extractor hood.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, eine Dunstabzugshaube der eingangs genannten Art so weiterzubilden, daß das Ausschwenken des beweglichen Filterteiles in der Handhabung erleichtert und im konstruktiven Aufbau vereinfacht wird.The invention seeks to remedy this. The invention, as characterized in the claims, solves the problem of developing an extractor hood of the type mentioned in such a way that the pivoting out of the movable filter part is easier to handle and the structural design is simplified.

Die durch die vorgeschlagene Ausbildung der Dunstabzugshaube erreichten Vorteile sind im wesentlichen darin zu sehen, daß mit einem äußerst geringen Materialeinsatz eine Dunstabzugshaube geschaffen wird, die neben ihrem raumsparenden Gesamtaufbau ein besonders weites Ausbringen des Filters über dem Küchenherd erlaubt und damit einen großen Ansaugebereich überdeckt. Des weiteren ist eine störungsfreie Handhabung gesichert, da für die beweglichen Teile keine ineinandergleitenden Führungsteile mit großen Reibungsflächen vorhanden sind.The advantages achieved by the proposed design of the extractor hood are essentially to be seen in the fact that an extractor hood is created with an extremely small amount of material, which, in addition to its space-saving overall construction, allows the filter to be extended particularly far above the kitchen range and thus covers a large suction area. Furthermore, trouble-free handling is ensured, since there are no sliding parts with large friction surfaces for the moving parts.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird an Hand dieser nachfolgend näher beschrieben. Es zeigt

  • Fig. 1 in geschnittener Darstellung eine Dunstabzugshaube, welche den unteren Bereich eines Küchenoberschrankes bildet, in Ruhestellung,
  • Fig. 2 die erste Phase des ausklappbaren Filters mit der einen Wrasen-Auffangschirm bildenden Frontplatte und
  • Fig. 3 die Dunstabzugshaube in Betriebs- bzw. Arbeitsstellung mit völlig herausgeklapptem Filter und ausgeschwenkter Frontplatte.
An embodiment of the invention is shown in the drawing and will be described in more detail below with reference to this. It shows
  • 1 is a sectional view of an extractor hood, which forms the lower area of a kitchen wall cabinet, in the rest position,
  • Fig. 2 shows the first phase of the fold-out filter with the front plate forming a vapor collecting screen and
  • Fig. 3, the extractor hood in operating or working position with the filter fully folded out and the front panel swung out.

Das Gehäuse 1 der Dunstabzugshaube befindet sich unterhalb eines Küchenoberschrankes 2 und schließt mit dessen Tür 2' an der Vorderseite bündig ab. Im Gehäuse 1 ist ein übliches Saugggebläse 3 untergebracht, vor dessen Ansaugseite ein Filter 4 zum Filtern der vom Gebläse 3 angesaugten Küchenluft angeordnet ist. Der Filter 4 ist zweiteilig ausgebildet, wobei der eine Filterteil 5 horizontal und starr im Gehäuse 1 untergebracht ist, während der andere Filter-Teil 6 in Ruhestellung im Gehäuse 1 eine senkrechte Stellung einnimmt und dort beweglich bzw. nach vorne zur Bedienungsseite hin herausklappbar gehaltert ist. Vor dem beweglichen Teil 6 des Filters 4 ist eine der Küchenmöbelfront angepaßte Frontplatte 7 als Abdeckung angeordnet, die mit der Tür 2' des Küchenoberschrankes 2 in einer Ebene liegt. In Ruhestellung des beweglichen Teils 6 des Filters 4 ist zwischen diesem und einer Gehäuse-Blende 8 eine bewegliche Deckplatte 9 vorgesehen, die am unteren freien Ende einen Haken 10 aufweist. Der Filter-Teil 6 bildet zusammen mit der beweglichen Deckplatte 9 und der Frontplatte 7 beim Ausschwenken eine bewegliche Einheit. Zu dieser Einheit kommen noch seitliche Doppelsegment-Klappen 13.The housing 1 of the extractor hood is located below a kitchen cupboard 2 and is flush with its door 2 'at the front. A conventional suction fan 3 is accommodated in the housing 1, and a filter 4 for filtering the kitchen air sucked in by the fan 3 is arranged in front of its suction side. The filter 4 is formed in two parts, the one filter part 5 being accommodated horizontally and rigidly in the housing 1, while the other filter part 6 assumes a vertical position in the rest position in the housing 1 and is held there in a movable manner or can be folded out towards the front on the operating side . In front of the movable part 6 of the filter 4, a front plate 7 adapted to the front of the kitchen furniture is arranged as a cover, which lies in one plane with the door 2 'of the kitchen cupboard 2. In the rest position of the movable part 6 of the filter 4, a movable cover plate 9 is provided between it and a housing cover 8, which has a hook 10 at the lower free end. The filter part 6 forms together with the movable cover plate 9 and the front plate 7 when pivoting out a movable unit. In addition to this unit there are lateral double-segment flaps 13.

Durch Ziehen an der Frontplatte 7 bewegen sich die Deckplatte 9 und die Frontplatte 7 um einen oberen Drehpunkt A, während sich das Filter-Teil 6 um einen unteren Drehpunkt 8 bewegt. Der bewegliche Filter-Teil 6 läßt sich dabei so weit ausschwenken, bis die Deckplatte 9 mit ihrem Haken-Ende 10 an der Unterkante der Gehäuse-Blende 8 anschlägt und damit das weitere Ausschwenken des Filter-Teils 6 beendet. Die Deckplatte 9 sowie dessen seitliche Segment-Klappen 11 bewirken, daß der erweiterte Saugraum 12 hinter dem Filter 4 (5, 6) nach allen Seiten hin geschlossen ist. Die Doppelsegment-Klappe 13 stellt sicher, daß bei ausgeschwenkter Frontplatte 7 keine Kochwrasen oder dgl. seitlich entweichen können.By pulling on the front plate 7, the cover plate 9 and the front plate 7 move about an upper pivot point A, while the filter part 6 moves about a lower pivot point 8 emotional. The movable filter part 6 can be swung out until the cover plate 9 strikes with its hook end 10 on the lower edge of the housing panel 8 and thus ends the further pivoting out of the filter part 6. The cover plate 9 and its lateral segment flaps 11 cause the expanded suction chamber 12 behind the filter 4 (5, 6) to be closed on all sides. The double-segment flap 13 ensures that when the front plate 7 is pivoted out, no cooking fumes or the like can escape laterally.

Durch diese Ausbildung der Dunstabzugshaube wird die effektive Filterfläche nach dem Ausschwenkvorgang gegenüber einer starren Anordnung des Filters um ca. 50% vergrößert. Auch ergibt sich durch das sehr weite Ausschwenken der Frontplatte 7 eine Vergrößerung der Saugfläche über dem Küchenherd, die je nach Höhenanordnung der Dunstabzugshaube zwischen 50 und 100% liegen kann.This design of the extractor hood increases the effective filter area by approximately 50% after the swing-out process compared to a rigid arrangement of the filter. The very wide swiveling out of the front plate 7 also results in an increase in the suction surface above the kitchen stove, which can be between 50 and 100%, depending on the height arrangement of the extractor hood.
