Abstract

The cooker hood has a vapor extraction hood in front of a filter. The extraction hood is formed as a funnel (5) with a smaller outlet opening (7) and an larger intake opening (6). The distance between intake and filter (3), the blower performance, and the funnel are adjusted relative to each other, so that the suction blowers (8) in the cooker hood (1) generate a suction effect in the extraction funnel. The filter surface is divided into individual filter sections (3.1-3.4), each with its own suction shaft, and with suction nozzle (9) or suction blower. The funnel is mounted on a horizontally moveable pivot lever (10).

Description

Die Erfindung betrifft eine Dunstabzugshaube, bei der das Absaugen der Wrasen und Dämpfe kochstellenbezogen erfolgt.The invention relates to a cooker hood, in which the suction of the vapors and Vapors takes place by boiling point.

Aus der DE 18 83 153 U1 ist eine Dunstabzugshaube bekannt, die über Mittel für eine Schiebe- und/oder Drehbewegung zum Zweck einer beweglichen Anbringung verfügt. Anwendung finden dabei Gleitschienen, Laufrollen und Scharniere. Dadurch ist es möglich, die Dunstabzugshaube über den Kochstellen seitlich und/oder nach vom zu verschieben, um über der den in Benutzung befindlichen Kochstellen ein intensives Absaugen der Dünste und Wrasen zu erreichen. Weiterhin ist ein Hochklappen an der Wand möglich.From DE 18 83 153 U1 an extractor hood is known, which has means for a Sliding and / or rotary movement has the purpose of a movable attachment. Sliding rails, rollers and hinges are used. That's it possible, the cooker hood over the hobs laterally and / or to from to to move over the hotplates in use an intensive Extracting the fumes and fumes to reach. Furthermore, a flip up at the Wall possible.

Ein Nachteil dieser Dunstabzugshaube besteht darin, dass durch das Verschieben über den Kochstellen natürlich "freie" Flächen verbleiben, auf denen sich nicht abgesaugte Dünste und Wrasen niederschlagen und zu Verschmutzungen führen.A disadvantage of this extractor hood is that by moving over Of course, the hobs remain "free" surfaces on which are not aspirated Beat down fumes and fumes and cause soiling.

Weiterhin ist aus der DE 41 42 474 A1 ist eine Dunstabzugshaube bekannt, die geteilte Absaugteile mit waagerecht angeordneten Filtern zum Absaugen der Wrasen und Dämpfe einerseits für die vorderen Kochstellen und andererseits für die hinteren Kochstellen des Küchenherdes aufweist.Furthermore, from DE 41 42 474 A1 an extractor hood is known, the divided Extraction units with horizontally arranged filters for extracting vapors and vapors on the one hand for the front cooking places and on the other hand for the rear cooking places of the Cooker has.

Dabei kommt eine mindestens dreiteilige Dunstabzugshaube zum Einsatz, wobei zwei Teile der getrennten Luftführung dienen und das dritte Teil den Abzugsblock mit Sauggebläsen darstellt.An at least three-part extractor hood is used, with two Parts of the separate air duct serve and the third part with the trigger block Suction blowers represents.

Die Absaugteile können getrennt sowie gemeinsam betrieben sein. Bei getrennter Absaugung wird jedes Sauggebläse durch einen eigenen Motor angetrieben, ansonsten reicht ein Motor für die beiden Sauggebläse aus.The suction can be separated and operated together. With separate Extraction, each aspirator is powered by its own motor, otherwise is sufficient for a motor for the two suction fan.

Der Nachteil dieser Dunstabzugshaube besteht darin, dass die Dunstabzugshaube aus drei Teilen zusammengesetzt ist, wobei zumindest die beiden Ansaugteile in sich geschlossen ausgeführt sein müssen, um den Austritt von angesaugten Dämpfen und Wrasen zu verhindern. Das macht die Dunstabzugshaube schwer.The disadvantage of this extractor hood is that the extractor hood three parts is composed, wherein at least the two intake parts in itself must be executed closed to the escape of aspirated vapors and Prevent vapors. This makes the cooker hood hard.

Die DE 198 10 818 A1 zeigt eine Abzugshaube gemäss Oberbegriff von Anspruch 1. Die Nachteile dieser Lösung bestehen zum einen in den Kosten für das zusätzliche Filter- und Lüftersystem und zum anderen im Einsatz des Schlauches zum Absaugen. Dieser verschmutzt leicht und wird im Haushalt deshalb wenig Akzeptanz finden.DE 198 10 818 A1 shows a fume hood according to Preamble of claim 1. The Disadvantages of this solution consist on the one hand in the cost of the additional filter and Fan system and the other in the use of the hose for suction. This pollutes easy and will therefore find little acceptance in the household.

Die Dunstabzugsvorrichtung nach der DE 199 07 057 A1 ist in der Küchenarbeitsplatte versenkt angeordnet. Sie wird zum Ansaugbetrieb nach oben ausgefahren und zum Gargutträger eingeschwenkt. Ihr Nachteil besteht zumindest darin, dass die Freifläche der Küchenarbeitsplatte eingeschränkt wird.The extractor device according to DE 199 07 057 A1 is in the kitchen worktop sunk. It is extended upwards for intake operation and for Food support swung in. Their disadvantage consists at least in that the open space of the Kitchen worktop is restricted.

Die in Fig. 1 dargestellte Dunstabzugshaube 1 besteht aus dem Gehäuse 2 mit dem darin angeordneten Filterrahmen 4 mit Filter 3. Unterhalb des Filters 3 ist der Absaugtrichter 5 mit einem lichten Abstand A zum Filter 3 angeordnet. Der Absaugtrichter 5 ist an einem schwenkbaren Schwenkhebel 10 geführt, der mittig im Rahmen des Filters 3 angeordnet ist. Durch einfaches Schwenken kann der Filter so den Teilfilterflächen 3.1 - 3.4 zugeordnet werden.The extractor hood 1 shown in Fig. 1 consists of the housing 2 with the therein arranged filter frame 4 with filter 3. Below the filter 3 is the suction funnel. 5 arranged with a clearance A to the filter 3. The suction funnel 5 is at a pivotable pivot lever 10 out, which is arranged centrally in the context of the filter 3 is. By simply tilting the filter can thus the sub-filter surfaces 3.1 - 3.4 be assigned.

In der dargestellten Ausführung ist die Dunstabzugshaube 1 durch Bleche in vier Abzugsräume geteilt, und jeder Teilfilterfläche 3.1 - 3.4 ist eine Lüfteransaugdüse 9 zugeordnet. Ebenso ist es möglich, jedem dieser Teilräume ein eigenes Lüftergebläse 8 zuzuordnen. Die Lüftergebläse 8 sind in der Drehzahl unabhängig voneinander steuerbar. Der Absaugtrichter 5 ist mit der Steuerung für die Drehzahl der Lüftergebläse 8 gekoppelt, derart, dass die Teilfilterflächen 3.1 - 3.4 entsprechend der Stellung des Absaugtrichters 5, der sich in der Darstellung bei der Teilfilterfläche 3.1 befindet, optimal abgesaugt werden.In the illustrated embodiment, the hood 1 through plates in four Deduction spaces divided, and each sub-filter surface 3.1 - 3.4 is a fan intake 9th assigned. It is also possible, each of these subspaces its own fan fan. 8 assigned. The fan blower 8 are independently controllable in speed. The suction funnel 5 is coupled to the speed control of the fan blower 8, such that the sub-filter surfaces 3.1 - 3.4 according to the position of the suction funnel 5, which is located in the representation at the sub-filter surface 3.1, optimally aspirated become.

In Fig. 2 weist die Dunstabzugshaube 1 kochstellenseitig unterhalb des Filters 3 im Bereich des Filterrahmens 4 parallel zu dessen Außenkanten verlaufende gegenüberliegende Führungsschienen 13 auf. Die Führungsschienen sind durch mindestens eine Querschiene 14 untereinander verbunden, wobei die Querschiene 14 entlang der Führungsschienen 13 verschiebbar ist und der Absaugtrichter 5 entlang der Querschiene 14. In Fig. 2, the hood 1 on the cooking side below the filter 3 in the area the filter frame 4 parallel to the outer edges extending opposite Guide rails 13 on. The guide rails are through at least one Cross rail 14 connected to each other, wherein the cross rail 14 along the guide rails 13 is displaceable and the suction funnel 5 along the cross rail fourteenth

Zwischen der Austrittsöffnung des Absaugtrichters 5 und dem Filter 3 im Filterrahmen 4 besteht der Abstand A. Er ist so bemessen, dass das oder die saugenden Lüftergebläse 8 in der Dunstabzugshaube 1 eine Sogwirkung im Absaugtrichter 5 erzeugen.Between the outlet opening of the suction funnel 5 and the filter 3 in the filter frame. 4 there is the distance A. It is dimensioned so that the or the sucking fan blower 8th produce a suction effect in the extractor 1 in the hood 1.

Neben der Lüfterdrehzahl, der Stellung des Absaugtrichters 5 und der Bemessung des Abstandes A hat natürlich die Ausbildung des Absaugtrichters 5 selbst großen Einfluss auf die Absaugwirkung. Entsprechende Absaugtrichterformen sind in den Fig. 2 bis 6 dargestellt.In addition to the fan speed, the position of the suction funnel 5 and the dimensioning of the Distance A of course has the formation of the suction funnel 5 itself great influence on the suction effect. Corresponding suction funnel shapes are shown in FIGS. 2 to 6 shown.

Die in Fig. 2 dargestellte Trompetenform für den Absaugtrichter 5 unterstützt die Kaminwirkung. Sie verhindert eine Verwirbelung der Grenzschicht, wodurch wenig gesättigte Luft an der Trichterfläche vorbeistreicht, was zu weniger Kondensat führt.The trumpet shape shown in Fig. 2 for the suction funnel 5 supports the Chimney effect. It prevents turbulence of the boundary layer, which means little saturated air passes the funnel surface, resulting in less condensate.

Der in Fig. 3 dargestellte Absaugtrichter ist perforiert. Die Öffnungen in Strömungsrichtung verhindern eine Kondensatablagerung durch die Zufuhr nichtgesättigter Raumluft.The suction funnel shown in Fig. 3 is perforated. The openings in the flow direction Prevent condensate deposits by supplying non-saturated room air.

Der in Fig. 4 dargestellte asymmetrische Absaugtrichter 5 ermöglicht ein zusätzliches Drehen vom Arbeitsbereich weg oder in den Wrasenbereich hinein.The asymmetrical suction funnel 5 shown in FIG. 4 allows an additional Turn away from the work area or into the vapor area.

Der Absaugtrichter 5 in Fig. 5 besteht aus einem Doppeltrichter und zeichnet sich durch eine gute Unterdruckerzeugung im oberen Absaugbereich aus.The suction funnel 5 in Fig. 5 consists of a double funnel and is characterized a good negative pressure generation in the upper suction.

Der in der Fig. 6 dargestellte Absaugtrichter 5 mit Luftleitblenden führt zur Stabilisierung des Wrasens unterhalb des Trichters.The suction funnel 5 with air guide orifices shown in FIG. 6 leads to stabilization the Wrasens below the funnel.

Die Erfindung sieht vor, dass der Absaugtrichter 5 bevorzugt aus Metall gefertigt ist. Dadurch wird ein schnelles Anpassen an die Dampftemperatur erreicht, was den Kondensatausfall reduziert. Weiterhin kann der Absaugtrichter 5 aus Metall außen eine Isolierung 11 aufweisen, wie in Fig. 7 dargestellt ist. Das Material in der Grenzschicht zum Dampf erwärmt sich hier noch schneller, wodurch der Kondensatausfall weiter sinkt. Darüber hinaus ist es auch möglich, den Absaugtrichter 5 zu heizen bzw. die Heizung 12 außen noch zusätzlich zu isolieren. Dies zeigen die Fig. 8 und 9. The invention provides that the suction funnel 5 is preferably made of metal. As a result, a quick adaptation to the steam temperature is achieved Condensate failure reduced. Furthermore, the suction funnel 5 made of metal outside a Insulation 11, as shown in Fig. 7. The material in the boundary layer to the Steam heats up even faster, which further reduces condensate loss. In addition, it is also possible to heat the suction funnel 5 and the heater 12th isolate on the outside in addition. This is shown in FIGS. 8 and 9.

Für die Ausbildung der Sogwirkung kann es auch von Vorteil sein, wenn der Absaugtrichter 5 in der Trichterhöhe verstellbar ist. Derartige Ausbildungen, einmal zusammengesetzt aus abschnittsweise überlagernden Kegelstumpfabschnitten und einmal durch eine Irisblendenausbildung sind in den Fig. 10 und 11 dargestellt.For the formation of the suction effect, it may also be advantageous if the Suction funnel 5 is adjustable in the funnel height. Such training, once composed of sections overlapping truncated cone sections and once by an iris formation are shown in Figs. 10 and 11.
