Abstract
Description
Die Erfindung betrifft eine Rückstauklappe zur Anordnung in einem Luftweg, insbesondere einer Dunstabzugsvorrichtung, der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to a backflow valve Arrangement in an airway, in particular an extractor device, the type mentioned in the preamble of claim 1.
Eine derartige Rückstauklappe ist hinlänglich bekannt und wird beispielsweise in der Dunstabzugshaube DA 316i der Fa. Miele & Cie GmbH & Co., Gütersloh verwendet, siehe Gebrauchs- und Montageanweisung, M.-Nr. 05 473 510. Die bekannte Rückstauklappe wird in einen Abluftweg der Dunstabzugshaube eingebaut und weist zwei um eine mittig angeordnete Achse drehbare Klappenteile auf, wobei die Drehbereiche der Klappenteile in der Einbaulage durch ein als an dem Abluftweg angeordneter Vorsprung ausgebildetes Gegenlager begrenzt sind. Auf der den Klappenteilen zugewandten Oberseite des Vorsprungs ist ein Dämpfungsmittel aus einem elastomeren Material aufgeklebt. Bei ausgeschaltetem Gebläse werden die beiden Klappenteile, unterstützt durch zwei Federn, in die Ruhelage überführt, in der die Klappenteile auf dem Dämpfungsmittel aufliegen und den Abluftweg im Wesentlichen blockieren.Such a backflow flap is well known and is used for example in the extractor hood DA 316i from Miele & Cie GmbH & Co., Gütersloh used, see instructions for use and assembly, M.no. 05 473 510. The well-known backflow valve is installed in an exhaust air duct of the extractor hood and points two flap parts rotatable about a centrally arranged axis, whereby the turning ranges of the flap parts in the installation position by an as Counter bearing formed on the exhaust air path are limited. On the top of the Projection is a damping agent glued from an elastomeric material. With the fan off the two flap parts, supported by two springs, brought into the rest position, in which the valve parts on the damping agent rest and essentially block the exhaust air path.
Aus der
Der Erfindung stellt sich das Problem eine Rückstauklappe anzugeben, bei der die Dämpfung bei der Überführung eines Klappenteils in dessen Ruhelage weiter verbessert ist.The invention poses the problem a backflow flap to specify at which the damping at the transfer of a Flap part in the rest position is further improved.
Erfindungsgemäß wird dieses Problem durch eine Rückstauklappe 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 is solved by a backflow flap solved with the features of claim 1. Advantageous configurations and further developments of the invention result from the following Dependent claims.
Die mit der Erfindung erreichbaren Vorteile bestehen neben einer verbesserten Dämpfung bei der Überführung eines Klappenteils in dessen Ruhelage insbesondere darin, dass keine zusätzlichen Bauteile erforderlich sind, sondern einfache konstruktive Maßnahmen und der Einsatz von Standardbauteilen den erfindungsgemäßen Erfolg zeitigen.The achievable with the invention There are advantages in addition to improved damping when transferring a Flap part in its rest position in particular that no additional components are required, but simple constructive measures and the use of standard components the success of the invention time.
Grundsätzlich ist das Gegenlager in Form, Art und räumlicher Anordnung in weiten geeigneten Grenzen wählbar. Zweckmäßigerweise ist das Gegenlager als ein an der Wand des Abluftwegs angeordneter Vorsprung ausgebildet.Basically, the counter bearing is in Shape, type and spatial Arrangement can be selected within wide suitable limits. Conveniently, the counter bearing is arranged on the wall of the exhaust air duct Lead.
Eine vorteilhafte Alternative zu der vorgenannten Ausführungsform sieht eine Haltevorrichtung vor, an der das Gegenlager angeordnet und das Klappenteil über die Achse drehbar gelagert ist. Auf diese Weise ist eine Ausbildung der erfindungsgemäßen Rückstauklappe als kompakte Baueinheit ermöglicht.An advantageous alternative to the aforementioned embodiment provides a holding device on which the counter bearing is arranged and the flap part over the axis is rotatably mounted. This is an education the backflow flap according to the invention enabled as a compact unit.
Eine andere vorteilhafte Weiterbildung sieht vor, dass das Federmittel in dem Bereich der Kontaktstelle mit dem Gegenlager als Rampe ausgebildet ist. Hierdurch ist die erfindungsgemäße Lehre auf einfache Weise verwirklicht.Another advantageous training provides that the spring means in the area of the contact point is designed as a ramp with the counter bearing. This is the teaching according to the invention realized in a simple way.
Eine besonders vorteilhafte Weiterbildung sieht vor, dass das Federmittel in dem Bereich der Kontaktstelle mit dem Gegenlager schenkelartig ausgebildet ist. Auf diese Weise ist die erfindungsgemäße Lehre mit geringem Materialeinsatz und auf konstruktiv einfache Weise verwirklicht.A particularly advantageous development sees before that the spring means in the area of the contact point with the Counter bearing is leg-shaped. In this way it is teaching according to the invention with little use of material and in a structurally simple manner realized.
Eine andere vorteilhafte Weiterbildung der erfindungsgemäßen Lehre sieht vor, dass das Federmittel als Metallteil ausgebildet ist, da eine Metallfeder ein kostengünstiges Standardbauteil ist.Another advantageous training the teaching of the invention provides that the spring means is designed as a metal part, because a metal spring is an inexpensive Standard component is.
Eine weitere vorteilhafte Weiterbildung sieht vor, dass das Federmittel an dem Klappenteil festgelegt und wenigstens teilweise als Schraubenfeder ausgebildet ist. Hierdurch ist die Befestigung des Federmittels an dem Klappenteil auf besonders einfache Weise ermöglicht. Ferner ist die Dämpfung weiter verbessert.Another advantageous training provides that the spring means fixed to the flap part and is at least partially designed as a coil spring. hereby the attachment of the spring means to the flap part is special enables simple way. Furthermore, the damping further improved.
Eine besonders vorteilhafte Weiterbildung sieht vor, dass das Federmittel lösbar mit dem Klappenteil bzw. dem Gegenlager verbunden ist und durch ein Sicherungsmittel in dessen Lage relativ zu dem Klappenteil bzw. dem Gegenlager im Wesentlichen festlegbar ist. Auf diese Weise ist beispielsweise ein nachträglicher Austausch des Federmittels vereinfacht, so dass nicht zwangsweise der Austausch der gesamten Rückstauklappe bzw. des Klappenteils erforderlich ist.A particularly advantageous development sees before that the spring means releasable is connected to the flap part or the counter bearing and by a securing means in its position relative to the flap part or the counter bearing is essentially fixable. That way for example a retroactive one Replacement of the spring means simplified, so that not necessarily the replacement of the entire backflow flap or the flap part is required.
Eine vorteilhafte Weiterbildung der vorgenannten Ausführungsform sieht vor, dass das Sicherungsmittel als Verprägung ausgebildet ist. Hierdurch ist das Sicherungsmittel auf besonders einfache Weise und damit kostengünstig verwirklicht.An advantageous development of aforementioned embodiment provides that the securing means is designed as embossing. This is the security means realized in a particularly simple manner and thus inexpensively.
