Abstract
Description
Die Erfindung betrifft einen Luftkanal für den Einbau in eine Wand mit einem ersten Kanalabschnitt, welcher in einen erweiterten Kanalabschnitt mündet und mit einer in Schließrichtung durch Gewichtskraft vorbelasteten selbsttätig gegen einen Anschlag schließenden schwenkbar gelagerten Rückstauklappe die in dem Luftkanal in Strömungsrichtung des von einem Gebläse erzeugten Luftstroms in die Offenstellung schwenkbar ausgebildet ist, wobei die Höhe der Vorbelastung der Rückstauklappe die Schwelle bestimmt, ab der die Öffnungsbewegung einsetzt und wobei der Rückstauklappe eine Sicherungseinrichtung zugeordnet ist, die bezogen auf die Schwenkachse der Rückstauklappe im unteren Bereich des Verschlussteils angeordnet ist und die Rückstauklappe bei nicht eingeschaltetem Gebläse in der Schließstellung hält, wobei die Rückstauklappe ein Verschlussteil mit einem daran angeformten Lagerabschnitt aufweist, der einstückig in einen umlaufenden Rand am Verschlussteil übergeht und eine Anschlagfläche bildet.The The invention relates to an air duct for installation in a wall with a first channel section which opens into an enlarged channel section and with one in the closing direction biased by gravity self-closing against a stop pivotally stored backflow flap in the air duct in the flow direction that of a blower generated air flow in the open position formed pivotable is, being the height the preload of the backflow flap determines the threshold from which the opening movement begins and the backflow flap a safety device is associated with respect to the pivot axis the backflow flap is arranged in the lower region of the closure part and the backflow flap when the fan is not switched on the closed position holds, where the backflow flap Having closure part with a bearing section integrally formed thereon, the one-piece merges into a peripheral edge on the closure part and forms a stop surface.

Bei den nach dem oben genannten Stand der Technik bekannten Luftkanälen verhindern die Rückstauklappen das Eindringen von Außenluft, wenn das Gebläse in der Abluftführung außer Betrieb ist. Außerdem wird durch die konstruktive Ausgestaltung ein Klappern bzw. unbeabsichtigtes Öffnen der Rückstauklappen bei wechselnden Druckverhältnissen im Luftkanal vermieden. Nachteilig ist jedoch, dass der in die Gebäudewand eingesetzte Luftkanal eine Kältebrücke zwischen Mauerkasten und Außenwand bilden kann.at Prevent the known according to the above-mentioned prior art air channels the backwater valves the ingress of outside air, though the blower in the exhaust air duct except Operation is. Furthermore is due to the structural design rattling or unintentional opening of the back pressure flaps with changing pressure conditions avoided in the air duct. The disadvantage, however, is that in the building wall used air duct a cold bridge between Wall box and outer wall can form.

Der Erfindung stellt sich somit das Problem einen Luftkanal ohne zusätzliche Stelleinrichtungen für eine Öffnungs- und Schließbewegung eines Verschlusses der Lüftungsöffnung durch eine luftstromgesteuerte schwenkbar gelagerte Rückschlagklappe, dahingehend zu verbessern, dass eine Kältebrücke zwischen Luftkanal und Außenwand vermieden wird und die Rückstauklappe bei ausgeschaltetem Gebläse den Luftkanal dichtend abschließt. Außerdem soll die Rückstauklappe ohne zusätzlichen motorischen Stellantrieb auch bei geringer Gebläseleistung einer an den Luftkanal angeschlossenen Dunstabzugshaube den Abluftweg frei geben.Of the Invention, thus, the problem is an air duct without additional Adjusting devices for an opening and closing movement a closure of the ventilation opening through an air flow controlled pivotally mounted check valve, to that effect to improve that a cold bridge between Air duct and outer wall is avoided and the backflow flap with the blower switched off sealing the air duct sealing. Furthermore should the backflow flap without additional motorized actuator even at low fan power to the air duct connected extractor hood the exhaust path free.
Erfindungsgemäß wird dieses Problem durch einen Luftkanal mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention this Problem by an air duct with the features of the claim 1 solved. Advantageous embodiments and further developments of the invention result from the following subclaims.
Die mit der Erfindung erreichbaren Vorteile bestehen darin, dass die Rückstauklappe infolge ihrer Rückstellkraft aus der Offenstellung in eine gesicherte Schließstellung fällt. Dies wird dadurch erreicht, dass der Massenschwerpunkt der Rückstauklappe in Schließrichtung außerhalb einer vom Schwenklager ausgehenden Lotachse der Rückstauklappe liegt. Bei äußeren Einwirkungen, wie beispielsweise Wind, ist die geschlossene Rückstauklappe außerdem gegen ungewolltes Flattern gesichert.The achievable with the invention advantages are that the return flap due to their restoring force from the open position falls into a secure closed position. This is achieved by that the center of gravity of the backwater flap in the closing direction outside one of the pivot bearing outgoing Lotachse the backwater flap lies. For external influences, such as wind, the closed backdoor is also against secured unwanted flutter.
Hierzu wirkt die Rückstauklappe mit einer Sicherungseinrichtung derart zusammen, dass diese infolge eines Druckanstieges im Luftkanal gegenüber einem Umgebungsdruck entriegelt wird, so dass die Rückstauklappe frei ist. Infolge eines Druckabfalls dp in dem Luftkanal wird die zurückfallende Rückstauklappe durch die Sicherungseinrichtung wieder in der Schließstellung gegen ein selbsttätiges Öffnen gesichert. Somit wird in dem Abluftkanal der Dunstabzugsvorrichtung sichergestellt, dass die Rückschlagklappe bei ausgeschaltetem Gebläse verschlossen ist. Die Sicherungseinrichtung ist als Magnetverschluss ausgebildet, wobei der Magnethalter bzw. Gegenpol vorzugsweise im Anschlag für die Rückstauklappe integriert ist und der Magnet an der schwenkbaren Rückstauklappe positioniert ist. Die Rückstauklappe ist mit einer thermischen Isolierung ausgebildet. Thermische Isolierung und Magnet erhöhen das Gewicht der Rückstauklappe und unterstützen das selbstständige Zurückfallen der Rückstauklappe in die Schließlage sowie das Halten in der Schließlage bei wechselnden Druckverhältnissen im Luftkanal bei ausgeschalteter Dunstabzugshaube. Die Sicherungseinrichtung ist derart dimensioniert und an das Gesamtgewicht der Rückstauklappe angepasst, dass die Entsicherung infolge des Druckanstiegs im Luftkanal selbsttätig auch bei niedriger Gebläseleistung einer an den Luftkanal angeschlossenen Dunst abzugshaube erfolgt, so dass sich ein ungehindertes Aufschwenken der Rückschlagklappe vollzieht und der Dunst an die Umgebung abgeblasen werden kann.For this acts the backflow flap with a safety device together such that these due a pressure increase in the air duct to an ambient pressure unlocked will, so the backflow flap free is. As a result of a pressure drop dp in the air duct is the falling back return flap by the securing device again in the closed position secured against self-opening. Thus, in the exhaust duct of the extractor device is ensured that the check valve with the blower switched off is closed. The safety device is as a magnetic closure formed, wherein the magnet holder or opposite pole preferably in Stop for the backflow flap is integrated and the magnet on the pivoting backflow flap is positioned. The backflow flap is formed with a thermal insulation. Thermal insulation and increase the magnet the weight of the backwater flap and support the independent one fall behind the backflow flap in the closed position and holding in the closed position with changing pressure conditions in the air duct with the cooker hood switched off. The safety device is dimensioned in such a way and to the total weight of the backflow flap adjusted that the arming due to the pressure rise in the air duct automatic even at low fan speed a connected to the air duct fume hood, so that an unobstructed swinging the check valve takes place and the haze can be blown off to the environment.
