In dem Gehäuse sind zwei schwenkbare Umleitklappen gelagert, die den Auslass bzw. die beiden seitlichen Auslässe absperren respektive öffnen, oder in einer Zwischenstellung der Auslass und die seitlichen Auslässe teilweise geöffnet sein können. Mit dieser Einrichtung ist eine einfache und effiziente Umleitung des Luftstromes geschaffen worden.In a device for diverting an air flow according to the document EP-A-2 290 298 a designed as a modular unit housing is provided, the inlet side in particular with an extractor hood and on the outlet side with an exhaust duct or with side outlets is connectable. In the housing, two pivotable Umleitklappen are stored, which shut off the outlet or the two side outlets respectively open, or in an intermediate position, the outlet and the side outlets may be partially open. With this device, a simple and efficient diversion of the air flow has been created.

Ausgehend von dieser Einrichtung ist der vorliegenden Erfindung die Aufgabe zugrundegelegt, eine gattungsmässige Dunstabzugshaube derart zu verbessern, dass mit ihr ohne grossen Mehraufwand eine optimale Luftreinigung erzielt und ferner eine den räumlichen Gegebenheiten vielseitigere Verwendung ermöglicht wird.Based on this device, the present invention is based on the object to improve a generic range hood so that it achieves optimal air purification without much extra effort and also a more versatile use of the spatial conditions is possible.

Erfindungsgemäss ist diese Aufgabe nach den Merkmalen des Anspruchs 1 bzw. des Anspruchs 12 gelöst.According to the invention this object is achieved according to the features of claim 1 and claim 12.

Bei der erfindungsgemässen Dunstabzugshaube ist wenigstens eine zusätzliche mittels eines betätigbaren Schliessorgans verschliessbare Ansaugstelle vorhanden, durch welche in ihrer Offenstellung bei eingeschaltetem Saugmotor ein Luftstrom von den Öffnungen in jeweils eine Kammer erfolgt.In the extractor hood according to the invention, at least one additional suction point which can be closed by means of an actuable closing element is provided, through which, in its open position when the suction motor is switched on, an air flow takes place from the openings into a respective chamber.

Mit dieser Ansaugstelle in der Abzugshaube kann eine erhebliche Verbesserung der Luftreinheit während und mitunter auch nach dem Kochen erzielt werden, bei dem die nicht erfassten Dünste grösstenteils abgesogen und in einen Abluftkanal geführt werden.With this suction in the fume hood can significantly improve air purity during and sometimes even after cooking be achieved, in which the unrecognized fumes are largely sucked and fed into an exhaust duct.

Die bei Umluftbetrieb durch die Öffnungen im Aussengehäuse ausgeblasene Luft, die in der Abzugshaube gereinigt worden ist, wird bei diesen Auslassöffnungen während oder nach dem Kochen ein weiteres Mal angesogen und beispielsweise durch den Filter in der Abzugshaube geführt und dabei nochmals gereinigt.The blown in the recirculation mode through the openings in the outer housing air that has been cleaned in the hood is sucked in these outlet openings during or after boiling a second time and performed, for example, through the filter in the hood and thereby cleaned again.

Diese Ansaugstellen sind vorteilhaft jeweils seitlich beim Gehäuse als längliche Durchgangsöffnungen mit mindestens einer verschwenkbaren Klappe als Schliessorgan ausgebildet. Damit kann eine optimale Ansaugung der Restdünste über die gesamte Breite der Öffnungen erfolgen.These suction points are advantageously each formed laterally at the housing as elongated passage openings with at least one pivotable flap as closing member.

Fig. 1 zeigt eine Dunstabzugshaube 30 mit einer Umleiteinrichtung 20 insbesondere für den Einbau in einer Küche oberhalb eines Kochfeldes oder dergleichen. Fig. 1 shows a cooker hood 30 with a diverter 20 in particular for installation in a kitchen above a hob or the like.

Diese Dunstabzugshaube 30 umfasst ein Aussengehäuse 35 mit einem unteren Einlass 31 und oberen seitlichen Öffnungen 13 14, darin ein Saugmotor 33 mit einem Auslass 32 sowie Filterkassetten 36, 37 angeordnet sind. Letztere umgeben den Saugmotor 33 derart, dass die vom Einlass 31 via die nicht gezeigte untere Haube angesaugte Luft vollständig durch diese reinigenden bzw. schalldämmenden Filterkassetten 36, 37 als Sorptionsfilter geleitet wird, bevor sie in den Saugmotor 33 und von diesem zum Auslass 32 gelangt.This extractor hood 30 comprises an outer housing 35 with a lower inlet 31 and upper lateral openings 13 14, in which a suction motor 33 with an outlet 32 and filter cassettes 36, 37 are arranged. The latter surround the suction motor 33 in such a way that the air sucked in from the inlet 31 via the lower hood, not shown, is led completely through these cleaning or sound-insulating filter cassettes 36, 37 as sorption filter, before it enters the suction motor 33 and from there to the outlet 32.

Zweckmässigerweise sind zwischen dem Aussengehäuse 35 und dem Saugmotor 33 entsprechende Kammern 38 gebildet, durch weiche die Luft vom Einlass 31 auch durch diese Kammern 38 gesaugt wird und dabei gleichmässig verteilt über ihre Filterflächen in den Saugmotor 33 gelangen.Conveniently, corresponding chambers 38 are formed between the outer housing 35 and the suction motor 33, through which the air from the inlet 31 is also sucked through these chambers 38 and thereby evenly distributed over their filter surfaces in the suction motor 33 pass.

Erfindungsgemäss ist beidseitig zu dem zentrisch angeordneten Auslass 32 oberhalb des Saugmotors 33 jeweils eine verschliessbare Ansaugstelle 27, 29 mit je einer länglichen Durchgangsöffnung 27', 29' zugeordnet, welche jeweils mit der jeweiligen seitlichen Öffnung 13, 14 beim Aussengehäuse 35 einerseits und via die separate Durchgangsöffnung 27', 29' zu den zwischen Saugmotor 33 und Aussengehäuse 35 vorgesehenen Kammern 38 andererseits geführt sind.According to the invention, a closable suction point 27, 29, each with an elongated through-opening 27 ', 29', is associated with the centrally arranged outlet 32 above the suction motor 33, each with the respective lateral opening 13, 14 on the outer housing 35 on the one hand and via the separate Through hole 27 ', 29' are guided on the other hand provided for between the suction motor 33 and outer housing 35 chambers 38.

Bei dem Aussengehäuse 35 erstrecken sich die Seitenwände üblicherweise bis zur Küchendecke. Die ihm zugeordneten Öffnungen 13, 14 mit schwenkbaren Lamellen 23 für den Umluftbetrieb sind ganz oben angeordnet, damit die Restdünste optimal abgesaugt werden. Es sind dabei jeweils mehrere nebeneinander angeordnete Lamellen 23 vorhangartig eingesetzt, welche darin schwenkbar um ihre Längsachse gelagert sind. Damit wird erreicht, dass die Auslassrichtung des Luftstroms je nach eingestellter Position der Lamellen 23 quer erfolgen kann.In the outer housing 35, the side walls usually extend to the kitchen ceiling. The associated openings 13, 14 with pivotable blades 23 for the recirculation mode are located at the top, so that the residual fumes are optimally sucked. There are in each case a plurality of juxtaposed slats 23 are used like a curtain, which are mounted therein pivotally about its longitudinal axis. This ensures that the outlet direction of the air flow can be done transversely depending on the adjusted position of the fins 23.

Zudem ist in dem Aussengehäuse 35 oberhalb des Auslasses 32 des Saugmotors 33 eine Umleiteinrichtung 20 mit zwei schwenkbar gelagerten Umleitklappen 24, 26 veranschaulicht. Es ist eine Auslassöffnung 28 für den Abluftbetrieb oberhalb der Umleitklappen 24, 26 angeordnet, an welche ein nicht näher gezeigtes nach aussen führendes Rohr anschliessbar ist.In addition, in the outer housing 35 above the outlet 32 of the suction motor 33, a diverter 20 with two pivotally mounted Umleitklappen 24, 26 illustrates. There is an outlet opening 28 for the exhaust air operation above the Umleitklappen 24, 26, to which a not shown in detail outwardly leading pipe can be connected.

Die beiden an ihrer Oberseite jeweils an einer Achse 24', 26' gelagerten Umleitklappen 24, 26 sind von der gezeigten in eine nach aussen geklappten Stellung verstellbar, so dass die vom Saugmotor 33 durch den Auslass 32 geförderte Luft entweder durch die obere Auslassöffnung 28 vorteilhaft nach aussen oder aber in der andern Stellung durch diese Auslassöffnungen 13, 14 zurück in den Raum geleitet wird. Diesen Umleitklappen 24, 26 sind an der Unterseite jeweils eine Leitklappe 44, 46 in paralleler Anordnung zugeordnet. Mit diesen Leitklappen 44, 46 ist insbesondere in der nach aussen geklappten Stellung, in der sie wie die Umleitklappen ebenfalls annähernd vertikal verlaufen, eine kanalförmige Luftführung zu den Ansaugstellen 27, 29 gebildet.The two deflecting flaps 24, 26 mounted on their upper side on an axle 24 ', 26' are adjustable from the position shown into an outwardly folded position, so that the air conveyed by the suction motor 33 through the outlet 32 is advantageous either through the upper outlet opening 28 is passed to the outside or in the other position through these outlet openings 13, 14 back into the room. These deflecting flaps 24, 26 are each assigned a guide flap 44, 46 in a parallel arrangement on the underside. With these baffles 44, 46 is in particular in the outwardly folded position in which they also extend approximately vertically as the Umleitklappen, a channel-shaped air duct to the suction points 27, 29 is formed.

Im Prinzip könnten diese Umleitklappen 24, 26 auch in eine einstellbare Zwischenstellung geschwenkt sein, bei welcher die Auslassöffnung 28 bzw. die seitlichen Öffnungen 13, 14 teilweise geöffnet wären.In principle, these deflecting flaps 24, 26 could also be pivoted into an adjustable intermediate position, in which the outlet opening 28 or the lateral openings 13, 14 would be partially opened.

In einer seitlichen Wandung des Aussengehäuses 35 ist im Rahmen der Erfindung eine nicht gezeigte elektrische Steuerungseinrichtung vorzugsweise für die gesamte elektrische Steuerung der Abzugshaube und der Ansaugstellen integriert. Diese elektrische Steuerungseinrichtung ist in der vorderen nicht gezeigten seitlichen Wandung des Aussengehäuses 35 als ein Elektroschrank untergebracht.In a lateral wall of the outer housing 35, an electrical control device, not shown, is preferably integrated for the entire electrical control of the hood and the suction in the context of the invention. This electrical control device is housed in the front side wall, not shown, of the outer housing 35 as an electrical cabinet.

Mit dieser Steuerungseinrichtung können die Schliessorgane der Ansaugstellen 27, 29 zumindest zu Beginn der Abluftführung oder bei voller Abluftleistung automatisch geschlossen werden. Wenn nun diese als Schliessorgane verwendeten Klappen 41, 42 geöffnet werden sollen, um die gereinigte Luft zur Abluftleitung oder nochmals durch die Filterkassetten zu leiten, kann dies entweder automatisch von der Steuerungseinrichtung oder manuell geschehen.With this control device, the closing organs of the intake points 27, 29 can be closed automatically at least at the beginning of the exhaust air duct or at full exhaust air output. If now these flaps used as closing organs 41, 42 are to be opened to direct the cleaned air to the exhaust duct or again through the filter cartridges, this can either be done automatically by the controller or manually.

Es könnte ausserdem eine intermittierende Steuerung vorgesehen sein, bei der abwechslungsweise einmal die Umleitklappen 24, 26 in die in Fig. 1 gezeigten Stellung für den Umluftbetrieb und anschliessend die Klappen 41, 42 geöffnet würden, so dass vorteilhaft während dem Kochen Restdünste, welche bei Umluftbetrieb durch die seitlichen Öffnungen 13, 14 wieder angesaugt und durch die Filterkassetten 37 geführt würden, nochmals gereinigt würden.It could also be provided an intermittent control, in which alternately once the Umleitklappen 24, 26 in the in Fig. 1 shown position for the recirculation mode and then the flaps 41, 42 would be opened, so that advantageously during cooking Residual fumes, which would be sucked in recirculation mode through the side openings 13, 14 and out through the filter cartridges 37, would be cleaned again.

Fig. 2 zeigt diese Umleiteinrichtung 20 in dem Aussengehäuse 35 mit den zwei schwenkbar gelagerten Umleitklappen 24, 26 in einem mehrteiligen Gehäuse 25. Es ist diese nach oben führende Auslassöffnung 28 für den Abluftbetrieb vorgesehen, die einen der Stellung der nach innen geklappten Umleitklappen angepassten Öffnungsquerschnitt aufweist. Fig. 2 shows this diverter 20 in the outer housing 35 with the two pivotally mounted Umleitklappen 24, 26 in a multi-part housing 25. It is provided upwardly leading outlet opening 28 for the exhaust air operation having a the position of the inwardly folded Umleitklappen adapted opening cross-section.

Vorteilhaft sind die Ansaugstellen 27, 29 mit ihren Durchgangsöffnungen 27', 29' am Gehäuse 25 befestigt, damit diese Umleiteinrichtung 20 und die Ansaugstellen als eine Baueinheit in die Dunstabzugshaube eingebaut werden können. Sie könnten aber auch als eigene Bauteile ausgeführt sein. Diese Durchgangsöffnungen 27', 29' erstrecken sich vorteilhaft über annähernd die gesamte Breite des Gehäuses 35, damit eine optimale Verteilung der ansaugenden Luft erfolgt.Advantageously, the suction points 27, 29 with their through holes 27 ', 29' attached to the housing 25 so that this diverter 20 and the suction can be installed as a unit in the hood. But they could also be designed as separate components. These passage openings 27 ', 29' extend advantageously over approximately the entire width of the housing 35, so that an optimal distribution of the sucking air takes place.

Fig. 3 zeigt teilweise die eine Ansaugstelle 27 mit der länglichen Durchgangsöffnung 27' und zudem die verschwenkbare Klappe 41 als Schliessorgan in der geöffneten Position. Es ist jeweils ein Gehäuseteil 21 in der Ansaugstelle 27 herausnehmbar eingesetzt, bei welchem ihre Durchgangsöffnung 27' in diese Kammer 38 direkt zum Saugmotor 33 führt. Fig. 3 shows partially the one suction 27 with the elongated passage opening 27 'and also the pivotable flap 41 as a closing member in the open position. In each case a housing part 21 in the suction point 27 is removably inserted, in which its passage opening 27 'leads into this chamber 38 directly to the suction motor 33.

Fig. 4 zeigt teilweise diese Ansaugstelle 27 und die verschwenkbare Klappe 41 in der geöffneten Position. Das Gehäuseteil 21 ist jedoch um 180° verdreht eingesetzt, so dass ihre Durchgangsöffnung 27' nicht direkt zum Saugmotor 33, sondern in die Kammer 38 ausserhalb der Filterkassette 37 führend ausgerichtet ist. Fig. 4 partially shows this suction 27 and the pivotable flap 41 in the open position. However, the housing part 21 is inserted rotated by 180 °, so that its passage opening 27 'is not aligned directly to the suction motor 33, but in the chamber 38 outside the filter cartridge 37 leading.

Mit dieser unterschiedlichen Einsetzbarkeit der Gehäuseteile 21, 22 ergibt sich ein weiterer Vorteil der Erfindung, dass je nach Gebrauch der Dunstabzugshaube 30 diese Rückführung der Restdünste entweder direkt zum Saugmotor und von diesem durch die Auslassöffnung 28 nach aussen oder aber durch die Filterkassetten 37 als Sorptionsfilter und vorteilhaft wieder zurück zu und durch die Öffnungen 13, 14 als Umluft erfolgt.With this different usability of the housing parts 21, 22 results in a further advantage of the invention that depending on the use of the hood 30 this return of the residual dusts either directly to the suction motor and from this through the outlet opening 28 to the outside or through the filter cassettes 37 as a sorption filter and advantageous again back to and through the openings 13, 14 takes place as circulating air.

Fig. 5 zeigt eine Umleiteinrichtung 10 analog wie diejenige nach Fig. 2 mit einem mehrteiligen kastenförmigen Gehäuse 15, welches eine untere Einlassöffnung 11, eine obere Auslassöffnung 12 für den Abluftbetrieb und wiederum zwei gegenüberliegende seitliche Auslassöffnungen 13', 14' für den Umluftbetrieb aufweist. Dem Gehäuse 15 sind zudem in seinem Innern zwei schwenkbar gelagerte Umleitklappen 24, 26 zugeordnet, mittels denen die Auslassöffnung 12 abgesperrt bzw. geöffnet und die beiden seitlichen Auslassöffnungen 13', 14' umgekehrt geöffnet bzw. geschlossen werden können. Fig. 5 shows a diverter 10 analogous to the one after Fig. 2 with a multi-part box-shaped housing 15, which has a lower inlet opening 11, an upper outlet opening 12 for the exhaust air operation and in turn two opposite lateral outlet openings 13 ', 14' for the recirculation mode. The housing 15 are also assigned in its interior two pivotally mounted Umleitklappen 24, 26, by means of which the outlet opening 12 is shut off or opened and the two lateral outlet openings 13 ', 14' reversed opened or closed.

Darüberhinaus sind erfindungsgemässe Ansaugstellen 16, 17 vorhanden, durch welche in ihren Offenstellungen jeweils ein Luftstrom von der einen Auslassöffnung 13', 14' zu einer separaten Durchgangsöffnung 16', 17' neben der zentrisch beim Gehäuse 15 angeordneten Einlassöffnung 11 erzeugbar ist. Mittels einer schwenkbar an jeweils einem Gehäuseteil 21, 22 gelagerter Klappe 18, 19 kann die entsprechende Ansaugstelle 16, 17 geöffnet oder geschlossen werden.In addition, inventive suction points 16, 17 are present, through which in their open positions in each case an air flow from the one outlet 13 ', 14' to a separate passage opening 16 ', 17' next to the centrally arranged at the housing 15 inlet opening 11 can be generated. By means of a pivotally mounted on each one housing part 21, 22 flap 18, 19, the corresponding suction point 16, 17 are opened or closed.

Im Unterschied zu dem Ausführungsbeispiel nach Fig. 2 ist die Auslassöffnung 12 für den Abluftbetrieb seitlich wegführend angeordnet. Zu diesem Zwecke ist ein oberhalb der Umieitklappen 24, 26 am Gehäuse 15 befestigbares Umlenkblech 12' angeordnet. Damit ergibt sich ein weiterer Vorteil insofern, als je nach Gegebenheit des Einbaus der Dunstabzugshaube diese Auslassöffnung direkt nach hinten angeschlossen werden kann.In contrast to the embodiment according to Fig. 2 the outlet opening 12 is arranged laterally leading away for the exhaust air operation. For this purpose, a above the Umieitklappen 24, 26 fastened to the housing 15 baffle 12 'is arranged. This results in a further advantage in that depending on the circumstances of the installation of the hood this outlet can be connected directly to the rear.

Diese Umleiteinrichtung 10 mit dem Gehäuse 15 ist als Modul gebaut und kann daher baukastenartig ohne speziellen konstruktiven Aufwand in einen Luftkanal integriert werden.This diverter 10 to the housing 15 is constructed as a module and can therefore be integrated into a modular manner without special design effort in an air duct.

Die Erfindung ist mit den obigen Ausführungsbeispielen ausreichend dargetan. Sie könnte aber noch durch andere Varianten veranschaulicht sein. So könnte je nach Gegebenheit der Anordnung der Dunstabzugshaube nur eine Ansaugstelle vorgesehen sein.The invention is sufficiently demonstrated with the above embodiments. But it could still be illustrated by other variants. Thus, depending on the circumstances of the arrangement of the hood only one suction point could be provided.

Zudem könnten die Öffnungen 13, 14 ausschliesslich für die Ansaugstelle dienen, durch welche Restdünste angesaugt werden, welche dann durch den Saugmotor und die Abluftleitung nach aussen befördert würde. Theoretisch könnte die Ansaugstelle auch über eine Leitung mit Aussenluft verbunden sein.In addition, the openings 13, 14 could serve exclusively for the suction, are sucked through which residual fumes, which then would be transported by the naturally aspirated engine and the exhaust duct to the outside. Theoretically, the intake could also be connected via a pipe to outside air.

Des weiteren könnte die Kammer 38 und der Saugraum als ein Raum ausgebildet sein, insbesondere wenn keine Filterkassette zwischen dem Saugmotor und dem Aussengehäuse vorgesehen wäre.Furthermore, the chamber 38 and the suction chamber could be formed as a space, in particular if no filter cartridge would be provided between the suction motor and the outer housing.

Im Rahmen der Erfindung könnten selbstverständlich auch diese verschliessbaren Ansaugstellen 27, 29 anders ausgestaltet sein. So könnten statt längliche Durchgangsöffnungen 27', 29' auch nur eine oder mehrere nebeneinander angeordnete Öffnungen und demnach könnte genauso jeweils mehr als eine Klappe 41, 42 vorgesehen sein.In the context of the invention, of course, these closable suction 27, 29 could be designed differently. Thus, instead of elongate passage openings 27 ', 29', only one or more openings arranged next to one another could be provided, and therefore more than one flap 41, 42 could be provided in the same way.
