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
Bei einer Einrichtung zum Umleiten eines Luftstroms gemäss der Druckschrift
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.

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
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,
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
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
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
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
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
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
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
Es könnte ausserdem eine intermittierende Steuerung vorgesehen sein, bei der abwechslungsweise einmal die Umleitklappen 24, 26 in die in
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
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
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
Im Unterschied zu dem Ausführungsbeispiel nach
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
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
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
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
