Description

Die Erfindung betrifft eine Dunstabzugshaube nach dem Oberbegriff des Anspruchs 1.The invention relates to an extractor hood according to the preamble of claim 1.

In der Druckschrift DE-U-201 22 340 ist bei einer Dunstabzugshaube ein Aussengehäuse mit einer luftdurchlässigen Wandung mit einem Paneel vorgesehen, durch welche der Luftstrom angesaugt und weiter durch einen Dom im Innern des Gehäuses, durch einen Schlauch und ein verstellbares Gitter in die Ansaugöffnung geleitet wird. Dieses Gitter kann mittels eines Verstellmotors hinsichtlich seines Öffnungsquerschnittes gesteuert werden, Damit lässt sich der Anteil des Luftstroms von dem Aussengehäuse ändern, aber es wird nicht eine Schliessfunktion ausgeübt. Daher wird entweder Luft vom Aussengehäuse permanent mit mehr oder weniger Menge angesaugt oder es wird Luft permanent durch das Gehäuse ausgestossen.In the pamphlet DE-U-201 22 340 an outer housing with an air-permeable wall with a panel is provided for an extractor hood, through which the air flow is sucked in and passed through a dome inside the housing, through a hose and an adjustable grille into the suction opening. This grille can be controlled with regard to its opening cross-section by means of an adjusting motor. This allows the proportion of the air flow from the outer housing to be changed, but a closing function is not exercised. Therefore, either more or less air is sucked in permanently from the outer housing or air is permanently expelled through the housing.

EP 1 843 100 A2 offenbart eine Vorrichtung zum Absaugen von Luft, umfassend eine Abluftvorrichtung, die mit einem Lufteinlass, einem Luftauslass und Verbindungsmitteln zum Verbinden des Luftauslasses der Abluftvorrichtung mit einem zentralen mechanischen Belüftungssystem versehen ist. EP 1 843 100 A2 discloses a device for extracting air comprising an exhaust device provided with an air inlet, an air outlet and connection means for connecting the air outlet of the exhaust device to a central mechanical ventilation system.

Bei einer Einrichtung zum Umleiten eines Luftstroms gemäss der Druckschrift EP-A-2 290 298 ist ein als modulare Baueinheit ausgebildetes Gehäuse vorgesehen, das einlassseitig insbesondere mit einer Dunstabzugshaube und auslassseitig mit einer Abluftleitung bzw. mit seitlichen Auslässen verbindbar ist. 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 housing designed as a modular unit is provided, which on the inlet side in particular with an extractor hood and on the outlet side with an exhaust air line or with lateral Outlets is connectable. Two pivotable diverting flaps are mounted in the housing, which shut off or open the outlet or the two lateral outlets, or in an intermediate position the outlet and the lateral outlets can 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.Proceeding from this device, the present invention is based on the object of improving a generic extractor hood in such a way that it achieves optimal air purification without great additional effort and also enables a more versatile use for the spatial conditions.

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, respectively.

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, there is at least one additional suction point that can be closed by means of an actuatable closing element, through which, in its open position, when the suction motor is switched on, an air flow takes place from the openings into each 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.This suction point in the extractor hood can significantly improve the air purity during and sometimes even after cooking can be achieved in which the vapors that have not been captured are largely sucked off and fed into an exhaust air 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 air blown out through the openings in the outer housing during recirculation mode, which has been cleaned in the extractor hood, is sucked in once more at these outlet openings during or after cooking and, for example, passed through the filter in the extractor hood and 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 designed in each case on the side of the housing as elongated through openings with at least one pivotable flap as a closing element. This means that the residual vapors can be optimally sucked in over the entire width of the openings.

Weitere vorteilhafte Einzelheiten der Dunstabzugshaube im Rahmen der Erfindung sind in den abhängigen Ansprüchen definiert.Further advantageous details of the extractor hood within the scope of the invention are defined in the dependent claims.

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 an extractor hood 30 with a diversion device 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 passed completely through these cleaning or sound-absorbing filter cassettes 36, 37 as sorption filters 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.Appropriately, 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 is evenly distributed over their filter surfaces into the suction motor 33.

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, on both sides of the centrally arranged outlet 32 above the suction motor 33, a closable suction point 27, 29 each with an elongated through opening 27 ', 29' is assigned, each with the respective lateral opening 13, 14 in the outer housing 35 on the one hand and via the separate Through opening 27 ', 29' to the chambers 38 provided between suction motor 33 and outer housing 35 on the other hand.

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 case of the outer housing 35, the side walls usually extend to the kitchen ceiling. The openings 13, 14 assigned to it, with pivotable lamellas 23 for circulating air operation, are arranged at the very top so that the residual vapors are optimally extracted. A plurality of slats 23 arranged next to one another are used in a curtain-like manner, which are mounted therein so as to be pivotable about their longitudinal axis. It is thereby achieved that the outlet direction of the air flow can take place transversely depending on the set position of the slats 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, a diversion device 20 with two pivotably mounted diversion flaps 24, 26 is illustrated in the outer housing 35 above the outlet 32 of the suction motor 33. An outlet opening 28 for the exhaust air operation is arranged above the diverting flaps 24, 26, to which an outwardly leading pipe (not shown in greater detail) 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 diverting flaps 24, 26, which are each mounted on an axis 24 ', 26' on their upper side, can be adjusted from the position shown to 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 outwards or in the other position through these outlet openings 13, 14 is passed back into the room. These diverter flaps 24, 26 are each assigned a guide flap 44, 46 in a parallel arrangement on the underside. With these guide flaps 44, 46 is in particular In the outwardly folded position, in which they, like the diverting flaps, also run approximately vertically, 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 diverting 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 open.

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 the context of the invention, an electrical control device (not shown) is integrated in a side wall of the outer housing 35, preferably for the entire electrical control of the extractor hood and the suction points. This electrical control device is accommodated in the front, not shown, side wall 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 elements of the suction points 27, 29 can be automatically closed at least at the beginning of the exhaust air flow or at full exhaust air output. If these flaps 41, 42, used as closing elements, are to be opened in order to direct the cleaned air to the exhaust air line or through the filter cassettes again, this can be done either automatically by the control device 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.An intermittent control could also be provided in which the diverting flaps 24, 26 alternately once in the in Fig. 1 position shown for the air circulation mode and then the flaps 41, 42 would be opened, so that advantageous during cooking Residual vapors, which would be sucked in again through the side openings 13, 14 and passed through the filter cassettes 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 diverting device 20 in the outer housing 35 with the two pivotably mounted diverting flaps 24, 26 in a multi-part housing 25. This upwardly leading outlet opening 28 is provided for the exhaust air operation, which has an opening cross-section adapted to the position of the inwardly folded diverting flaps.

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.The suction points 27, 29 are advantageously attached to the housing 25 with their through openings 27 ', 29' so that this diverting device 20 and the suction points can be built into the extractor hood as a single unit. But they could also be designed as separate components. These through openings 27 ', 29' advantageously extend over almost the entire width of the housing 35, so that the air being sucked in is optimally distributed.

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 partially shows the one suction point 27 with the elongated through opening 27 'and also the pivotable flap 41 as a closing member in the open position. In each case, a housing part 21 is removably inserted in the suction point 27, 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 point 27 and the pivotable flap 41 in the open position. The housing part 21, however, is inserted rotated by 180 °, so that its through opening 27 'is not aligned directly to the suction motor 33, but rather into the chamber 38 outside the filter cassette 37.

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 there is a further advantage of the invention that, depending on the use of the extractor hood 30, this return of the residual vapors either directly to the suction motor and from there through the outlet opening 28 to the outside or through the filter cassettes 37 as a sorption filter and advantageously back to and through the openings 13, 14 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 diversion device 10 analogous to that according to 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 circulating air operation. The interior of the housing 15 is also assigned two pivotably mounted diverting flaps 24, 26, by means of which the outlet opening 12 can be shut off or opened and the two lateral outlet openings 13 ', 14' can be opened or closed conversely.

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, there are suction points 16, 17 according to the invention, through which, in their open positions, an air flow can be generated from one outlet opening 13 ', 14' to a separate through opening 16 ', 17' next to the inlet opening 11 arranged centrally at the housing 15. The corresponding suction point 16, 17 can be opened or closed by means of a flap 18, 19 mounted pivotably on a respective housing part 21, 22.

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 Umleitklappen 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 for the exhaust air operation is arranged to lead away laterally. For this purpose, a baffle plate 12 'that can be fastened to the housing 15 above the diverting flaps 24, 26 is arranged. This results in a further advantage in that, depending on the installation of the extractor hood, this outlet opening 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 diversion device 10 with the housing 15 is built as a module and can therefore be integrated into an air duct like a modular system without any special structural effort.

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 also be illustrated by other variants. Depending on the arrangement of the extractor 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 point through which residual vapors are sucked in, which then would be transported to the outside by the suction motor and the exhaust air duct. Theoretically, the suction point could also be connected to outside air via a pipe.

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 space could be designed as one space, in particular if no filter cassette were 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, these closable suction points 27, 29 could of course also be configured differently. Thus, instead of elongated through openings 27 ', 29', only one or more openings arranged next to one another and accordingly more than one flap 41, 42 could be provided in each case.
