Bei einem gattungsgemäßen Dachlüfter, bei dem sämtliche sichtbaren Bestandteile aus Ton bestehen, werden die einzeln gefertigten Teile miteinander verklebt. Aufgrund des verwendeten Materials und der dadurch beschränkten Fertigungsmöglichkeiten ist die Durchströmungszone unterhalb der Kappe nicht optimal. Darüber hinaus sind derartige Dachlüfter schwer wartbar.In a generic roof vent, in which all visible components are made of clay, the individually manufactured parts are glued together. Due to the material used and the resulting limited manufacturing capabilities, the flow zone below the cap is not optimal. In addition, such roof fans are difficult to maintain.

Der Erfindung liegt daher die Aufgabe zugrunde, den gattungsgemäßen Dachlüfter gebrauchsvorteilhaft zu verbessern.The invention is therefore based on the object to improve the generic roof ventilator use advantage.

Gelöst wird die Aufgabe durch die in den Ansprüchen angegebene Erfindung.The object is achieved by the invention specified in the claims.

Zunächst und im Wesentlichen ist vorgesehen, dass die Kappe von einem Kappenträger getragen wird, der aus Kunststoff besteht. Es ist zumindest ein Befestigungselement vorgesehen, mit dem die Kappe lösbar am Kappenträger befestigt ist. Anders als beim Stand der Technik wird mit dem Befestigungselement die gesamte Kappe am Kappenträger befestigt. Wird das Befestigungselement gelöst, so kann die gesamte Kappe vom Kappenträger abgenommen werden. Der Kappenträger stützt sich bevorzugt auf dem dachaußenseitigen Stirnrand des Lüftungsrohres ab. Während das Lüftungsrohr und die Kappe aus Ton, Beton oder einem anderen mineralischen Werkstoff, beispielsweise aber auch einem mineralischen Faserverbundwerkstoff gefertigt ist, besteht der Kappenträger vorzugsweise aus Kunststoff. Er ist so gestaltet, dass er sich im Spritzgussverfahren fertigen lässt. Die Befestigung des Kappenträgers am Lüftungsrohr beziehungsweise an der Kappe erfolgt mittels Befestigungselementen, die das Lüftungsrohr durchgreifen können. Das mindestens eine Befestigungselement hält sowohl die Kappe am Kappenträger als auch den Kappenträger am Lüftungsrohr. Es erfüllt somit eine Doppelfunktion. Die Kappe kann dichten auf einem Oberteil des Kappenträgers aufliegen. Das Oberteil kann somit eine geschlossene Fläche ausbilden. Zwischen dem Oberteil und einem Kappenträgerunterteil erstrecken sich Tragstege. Die Öffnungen zwischen den Tragstegen bilden eine Durchströmungszone, durch die Luft aus dem Lüftungsrohr austreten kann. Die Luft wird dabei um 90° umgelenkt. Sie strömt bezogen auf die Achsrichtung des Lüftungsrohres in Radialrichtung aus den Zwischenräumen zwischen den Tragstegen. Es ist insbesondere vorgesehen, dass die Befestigungselemente gegen den Rand der dachinnenseitigen Öffnung des Lüftungsrohres vorgespannt werden können. An der dachinnenseitigen Öffnung des Lüftungskanales kann ein Adapter sitzen. Dieser Adapter kann das Widerlager der Befestigungselemente sein. Der Adapter kann aber auch zum Anschluss eines Entlüftungsrohres oder eines Fallrohres dienen. Er besitzt hierzu einen Anschlussstutzen, der mit dem Fallrohr verbindbar ist beziehungsweise in die Höhlung eines Fallrohres eingesteckt werden kann. Die Befestigungselemente können Öffnungen des Adapters durchragen. Sie können zumindest an ihren Enden ein Außengewinde aufweisen. Die Befestigungselemente können beispielsweise von Gewindestangen gebildet sein, die jeweils eine Öffnung des Adapters durchgreifen. Sie sind mit einer Mutter gesichert. Sie können mit dem Adapter auch verhakt werden und hierzu einen Haken aufweisen. Ein derart gestaltetes Befestigungselement kann aber auch unmittelbar mit dem dachinnenseitigen Rand des Lüftungsrohres verhakt werden. Bevorzugt sind zwei Befestigungselemente vorgesehen. Der Kappenträger kann einen oberen Abschnitt aufweisen, der die Kappe trägt. Die Kappe besitzt einen Dachabschnitt und einen Wandabschnitt. Der Dachabschnitt überfängt den Kappenträger. Der Dachabschnitt der Kappe besitzt vorzugsweise Öffnungen, durch die die Befestigungselemente hindurchragen können. Mittels Muttern, die auf die Enden der Befestigungselemente aufgeschraubt sind, wird die Kappe am Dachlüfter befestigt. Auch der Kappenträger kann mittels der Befestigungselemente, beispielsweise mittels Muttern, am Lüftungsrohr befestigt werden. Die Befestigungselemente halten somit unabhängig voneinander den Kappenträger und die Kappe, so dass die Kappe vom Kappenträger zu Wartungszwecken gelöst werden kann. Die Befestigungselemente sind vorzugsweise Zugstangen, die zumindest auf ihrer Dachaußenseite weisenden Seite ein Gewinde aufweisen, auf das eine Mutter aufgeschraubt ist. Bevorzugt sind zwei Muttern vorgesehen. Eine Mutter hält den Kappenträger, eine zweite Mutter hält die Kappe. Der Kappenträger kann einen Stützrahmen aufweisen, der auf dem Stirnrand des Lüftungsrohres aufliegt. Von dem Stützrahmen können Tragstege abragen. Diese können spitzwinklig zueinander verlaufen. Die Tragstege tragen eine das Dach des Kappenträgers bildende Strömungsleitfläche. Die Strömungsleitfläche kann eine Wölbung aufweisen. Es kann sich dabei um eine "sombreroartige" Wölbung handeln, die ringförmig einen zentralen, hin zum Lüftungsrohr weisenden Fortsatz umgibt, der einen Scheitelpunkt ausbildet. Die Durchströmungszone, in der sich die Tragstege befinden, wird bevorzugt vollständig von den Wandabschnitten der Kappe umgeben. Der Abstand des Randes des Wandabschnittes der Kappe zur Dacheindeckungsplatte ist bevorzugt geringer als der Abstand des dachaußenseitigen Randes des Lüftungsrohres zur Dacheindeckungsplatte. Das Lüftungsrohr kann materialeinheitlich mit der Dacheindeckungsplatte verbunden sein. Es ist aber auch möglich, das Lüftungsrohr in eine zuvor in eine Dacheindeckungsplatte eingebrachte Öffnung einzukleben. Die Öffnung kann beispielsweise durch Wasserstrahlschneiden gefertigt sein.First and foremost, it is provided that the cap is supported by a cap carrier made of plastic. It is at least a fastener provided, with which the cap is releasably attached to the cap carrier. Unlike the prior art, the entire cap is attached to the cap carrier with the fastener. If the fastener is released, the entire cap can be removed from the cap carrier. The cap carrier is preferably supported on the roof outside edge of the vent pipe. While the vent pipe and the cap made of clay, concrete or other mineral material, but for example, a mineral fiber composite material is made, the cap carrier is preferably made of plastic. It is designed so that it can be manufactured by injection molding. The attachment of the cap carrier on the vent pipe or on the cap by means of fasteners that can pass through the vent pipe. The at least one fastening element holds both the cap on the cap carrier and the cap carrier on the ventilation pipe. It thus fulfills a dual function. The cap can rest tightly on an upper part of the cap carrier. The upper part can thus form a closed surface. Between the upper part and a cap carrier lower part support webs extend. The openings between the support webs form a flow zone through which air can escape from the ventilation pipe. The air is deflected by 90 °. It flows radially relative to the axial direction of the ventilation tube from the spaces between the support webs. It is particularly provided that the fasteners can be biased against the edge of the roof inside opening of the ventilation pipe. On the inside roof opening of the ventilation duct, an adapter can sit. This adapter may be the abutment of the fasteners. The adapter can also serve to connect a vent pipe or a downpipe. He has for this purpose a connection piece, which is connectable to the downpipe or can be plugged into the cavity of a downpipe. The fasteners can protrude through openings of the adapter. You can have at least at their ends an external thread. The fastening elements may be formed, for example, by threaded rods, which pass through an opening of the adapter. You are secured with a mother. You can also be hooked with the adapter and this have a hook. Such a designed fastener but can also be hooked directly to the roof inside edge of the ventilation pipe. Preferably, two fastening elements are provided. The cap carrier may have an upper portion that supports the cap. The cap has a roof section and a wall section. The roof section overhangs the cap carrier. The roof portion of the cap preferably has openings through which the fasteners may protrude. By means of nuts, which are screwed onto the ends of the fasteners, the cap is attached to the roof vent. The cap carrier can also be fastened to the ventilation pipe by means of the fastening elements, for example by means of nuts. The fasteners thus independently hold the cap carrier and the cap, so that the cap can be released from the cap carrier for maintenance purposes. The fastening elements are preferably tie rods, which have at least on their roof outside facing side a thread on which a nut is screwed. Preferably, two nuts are provided. A mother holds the cap carrier, a second mother holds the cap. The cap carrier may have a support frame which rests on the end edge of the ventilation tube. From the support frame support bars may protrude. These can run at an acute angle to each other. The support webs carry a the roof of the cap carrier forming flow guide. The flow guide can have a curvature. It may be a "sombreroartige" curvature, which surrounds a ring-shaped central, pointing to the vent pipe extension, which is a vertex formed. The flow-through zone in which the support webs are located is preferably completely surrounded by the wall sections of the cap. The distance of the edge of the wall portion of the cap to the roofing plate is preferably less than the distance of the roof outer side edge of the ventilation tube to the roofing plate. The ventilation pipe can be connected in the same material as the roofing panel. But it is also possible to glue the ventilation pipe in a previously introduced into a roofing plate opening. The opening can be made for example by water jet cutting.

Der in den Zeichnungen dargestellte Dachlüfter ist als Dacheindeckungsplatte in eine Dachhaut einsetzbar. Die Dacheindeckungsplatte 1 besitzt eine Öffnung, die durch Wasserstrahlschneiden gefertigt werden kann. Innerhalb der Öffnung erstreckt sich ein Lüftungsrohr 3, welches eine dachaußenseitige Öffnung 4 und eine dachinnenseitige Öffnung 5 ausbildet. Die dachaußenseitige Öffnung 4 wird vom Rand 6 des Lüftungsrohres 3 umgeben und besitzt einen Abstand A von der Dacheindeckungsplatte 1. Die Dacheindeckungsplatte 1 und das Lüftungsrohr 3 sind ebenso wie eine Kappe 8 aus Ton, Beton oder einem anderen Nicht-Kunststoffmaterial gefertigt. Das Lüftungsrohr 3 kann aber auch materialeinheitlich mit der Dacheindeckungsplatte 1 verbunden sein.The roof vent shown in the drawings can be used as roofing plate in a roof skin. The roofing plate 1 has an opening that can be made by water jet cutting. Within the opening extends a vent pipe 3, which forms a roof outside opening 4 and a roof inside opening 5. The roof outer side opening 4 is surrounded by the edge 6 of the ventilation tube 3 and has a distance A from the roofing plate 1. The roofing plate 1 and the ventilation pipe 3 are just like a cap 8 made of clay, concrete or other non-plastic material. But the vent tube 3 may also be connected to the roof covering plate 1 of the same material.

Die Kappe 8 besitzt einen Dachabschnitt 9 und einen den Dachabschnitt 9 umgebenden Wandabschnitt 10 mit einem zur Dacheindeckungsplatte 1 ragenden Rand 11, dessen Abstand B von der Dacheindeckungsplatte 1 geringer ist, als der Abstand A des Stirnrandes 6 des Lüftungsrohres 3 von der Dacheindeckungsplatte 1. Die Kappe 8 hat die Form einer Schüssel, die im Gebrauchszustand der Kappe 8 mit ihrem Boden nach oben und mit ihrem Rand nach unten weist.The cap 8 has a roof portion 9 and a wall portion 10 surrounding the roof portion 9 with an edge 11 projecting to the roofing plate 1 whose distance B from the roofing plate 1 is less than the distance A of the end edge 6 of the ventilation tube 3 from the roofing plate 1 Cap 8 has the shape of a bowl which, in use, faces the cap 8 with its bottom up and its edge down.

Das Lüftungsrohr 3 ist derart in die Öffnung der Dacheindeckungsplatte 1 eingeklebt, dass der untere Stirnrand 7 geringfügig unter die Unterseite der Dacheindeckungsplatte 1 ragt. Auf diesem Rand 7 sitzt ein Kragen eines Adapters 22. Der Adapter 22 bildet mit seinem Kragen einen Stützrahmen 23 aus, der sich am Rand 7 des Lüftungsrohres 3 abstützt. Der Adapter 22 bildet darüber hinaus einen Anschlussflansch 24 aus, der in eine Öffnung eines dachinnenseitigen Fall- oder Lüftungsrohres 25 eingreift. Es sind zumindest zwei, gegebenenfalls aber auch drei oder vier Befestigungselemente 21 vorgesehen, die beim Ausführungsbeispiel von Zugstangen ausgebildet sind. Beim Ausführungsbeispiel handelt es sich um Gewindestangen 21, die auf ihrer gesamten Länge, zumindest aber in ihren Endabschnitten ein Außengewinde tragen. Das nach unten weisende Ende des Befestigungselementes 21 trägt einen Radialvorsprung, der von einer auf das Ende des Befestigungselementes 21 aufgeschraubten Mutter ausgebildet sein kann. Das Ende des Befestigungselementes 21 steckt in einer Öffnung des Adapters 22, so dass nach oben gerichtete Zugkräfte auf den Adapter 22 aufgebracht werden können.The ventilation pipe 3 is glued into the opening of the roofing plate 1 such that the lower end edge 7 protrudes slightly below the underside of the roofing plate 1. On this edge 7 sits a collar of an adapter 22. The adapter 22 forms with its collar a support frame 23, which is supported on the edge 7 of the ventilation tube 3. The adapter 22 also forms a connection flange 24, which engages in an opening of a roof inside the fall or vent pipe 25. There are at least two, but optionally also three or four fastening elements 21 are provided, which are formed in the embodiment of tie rods. In the embodiment they are threaded rods 21 which carry an external thread over their entire length, but at least in their end portions. The downwardly facing end of the fastener 21 carries a radial projection, which may be formed by a screwed onto the end of the fastener 21 nut. The end of the fastener 21 is inserted in an opening of the adapter 22, so that upward tensile forces can be applied to the adapter 22.

Auf dem zur Dachaußenseite weisenden Rand 6 des Lüftungsrohres 3 sitzt ein Stützrahmen 13 eines Kappenträgers 12. Der Stützrahmen 13 wird von einem unteren Abschnitt des Kappenträgers 12 ausgebildet. Vom Stützrahmen 13 ragen sich gegenüberliegende Tragstege 15, 17 ab. Die beiden Tragstege 15, 17 des Kappenträgers 12 sind mit einer Strömungsleitwand miteinander verbunden, die Öffnungen aufweist, durch die die Befestigungselemente 21 hindurchragen. Mittels Muttern 28, die auf die Befestigungselemente 21 aufgeschraubt sind, wird der Kappenträger 12 gegen den Rand 6 des Lüftungsrohres 3 verspannt. Die diesbezügliche Spannkraft wird über den Adapter 22 in den gegenüberliegenden Rand 7 eingeleitet.On the outside of the roof facing edge 6 of the vent tube 3 sits a support frame 13 of a cap carrier 12. The support frame 13 is formed by a lower portion of the cap carrier 12. From the support frame 13 protrude opposite support webs 15, 17 from. The two support webs 15, 17 of the cap carrier 12 are connected to one another with a flow guide having openings through which the fasteners 21 protrude. By means of nuts 28 which are screwed onto the fastening elements 21, the cap carrier 12 is braced against the edge 6 of the ventilation tube 3. The relevant clamping force is introduced via the adapter 22 in the opposite edge 7.

Es sind V-förmig angeordnete Tragstege 16 vorgesehen, die ebenso wie die Tragstege 15, 17 eine Luftleitfläche 19 des oberen Abschnittes 18 des Kappenträgers 12 tragen. Die Luftleitfläche 19 ist zu einem Scheitelpunkt 20 hin gewölbt. Der Scheitelpunkt 20 wird von einem Vorsprung ausgebildet, der vom oberen Abschnitt 18 in Richtung auf das Lüftungsrohr 3 ragt. Der Bereich zwischen der Luftleitfläche 19 des oberen Abschnittes 18 des Kappenträgers 12 und dem unteren Abschnitt 13 des Kappenträgers 12 bildet einen mittleren Abschnitt 14, der eine Durchströmungszone bildet, durch den Luft aus dem Lüftungskanal 2 austreten kann. Die Tragstege 15, 16, 17 sind so angeordnet, dass ihre Schmalseiten in Stromrichtung liegen, so dass die Tragstege 15,16,17 den geringsten Strömungswiderstand liefern.There are provided V-shaped support webs 16 which, like the support webs 15, 17 carry an air guide surface 19 of the upper portion 18 of the cap carrier 12. The air guide 19 is curved towards a vertex 20. The apex 20 is formed by a projection which projects from the upper portion 18 in the direction of the ventilation pipe 3. The area between the air guide surface 19 of the upper portion 18 of the cap carrier 12 and the lower portion 13 of the cap carrier 12 forms a central portion 14 which forms a flow zone through which air can escape from the ventilation channel 2. The support webs 15, 16, 17 are arranged so that their narrow sides are in the direction of flow, so that the support webs 15,16,17 provide the lowest flow resistance.

Der Abschnitt 18 des Kappenträgers 12, der die Luftleitfläche 19 ausbildet, besitzt einen in etwa ovalen Grundriss. Der Abschnitt 18 bildet die als Freiformfläche ausgebildete Luftleitfläche 19. Etwa zum Zentrum des Lüftungsrohres 18 besitzt die Luftleitfläche 19 einen nach unten gerichteten Vorsprung. In radial Außenrichtung schließt sich an den Scheitelpunkt 20 des Vorsprungs eine konvex gewölbte Fläche an, die zum Rand der Luftleitfläche 19 in eine Horizontalrichtung übergeht.The portion 18 of the cap carrier 12, which forms the air guide 19, has an approximately oval floor plan. The section 18 forms the free-form surface designed as an air guide surface 19. Approximately to the center of the ventilation tube 18, the air guide 19 has a downwardly directed projection. In the radially outer direction adjoins the apex 20 of the projection to a convex curved surface, which merges into the edge of the air guide 19 in a horizontal direction.

Auf dem oberen Abschnitt 18 des aus Kunststoff gefertigten Kappenträgers 12 liegt der Dachabschnitt 9 der aus Ton oder einem anderen geeigneten Nicht-Kunststoff gefertigten Kappe 8. Der Dachabschnitt 9 der Kappe 8 besitzt Öffnungen 26, durch die die Endabschnitte der Befestigungselemente 21 hindurchragen. Die Endabschnitte der Befestigungselemente 21 besitzen jeweils ein Außengewinde, so dass die Kappe 8 mittels zwei auf das Außengewinde aufgeschraubter Muttern 27 am Lüfter befestigt werden können. Durch Lösen der Muttern 27 kann die Kappe 8 zu Wartungszwecken abgenommen werden. Dann kann der Kappenträger 12 gereinigt oder im Bedarfsfall auch ausgetauscht werden. Zum Austausch des Kappenträgers 12 sind die Muttern 28 zu lösen.On the upper portion 18 of the cap carrier made of plastic 12 is the roof portion 9 of the made of clay or other suitable non-plastic cap 8. The roof portion 9 of the cap 8 has openings 26 through which the end portions of the fasteners 21 protrude. The end portions of the fasteners 21 each have an external thread, so that the cap 8 can be attached by means of two screwed onto the external thread nuts 27 on the fan. By loosening the nuts 27, the cap 8 can be removed for maintenance purposes. Then the cap carrier 12 can be cleaned or replaced if necessary. To replace the cap carrier 12, the nuts 28 are to be solved.

Es wird als vorteilhaft angesehen, dass die Tonkappe nicht auf das aus Ton gefertigte Rohr aufgeklebt werden muss. Es kann ein Kunststoff-Zwischenteil in Form des Kappenträgers 12 verwendet werden, welches im Bereich der Durchlüftungszone 14 einen maximalen Lüftungsquerschnitt aufweist. Die Unterkonstruktion aus Kunststoff wird über Formschlussmittel mit der Dacheindeckungsplatte 1 verbunden. Es handelt sich bevorzugt um eine lösbare Verankerung. Die Formschlussverbindung erfolgt vorzugsweise über die Gewindestangen 21. Dadurch ist es möglich, die Kappe 8 über eine Verschraubung an der Dacheindeckungsplatte 1 zu sichern. Eine Demontage der Kappe 8 zu Revisionszwecken ist dadurch möglich. Adapter 22 und Anschlussrohr 25 können aber auch einteilig sein. Wie der Figur 7 zu entnehmen ist, bildet der Adapter 22 eine Stufe aus, auf der sich der untere Rand 7 des Lüftungsrohres 3 abstützen kann. An der tiefsten Stelle dieser Stufe befindet sich in einem Eckbereich eine Öffnung 29. Es sind insgesamt zwei Durchtrittsöffnungen 29 vorgesehen, durch die eventuell anfallendes Kondenswasser auf eine Dachunterspannbahn ableitet, die sich auf der dachinnenseitigen Seite der Dacheindeckungsplatte 1 erstreckt. Der Kappenträger 12 erlaubt durch seine Ausführung die Realisierung vergleichsweiser großer Strömungsquerschnitte durch den mittleren Abschnitt 14. Der Kappenträger 12 ist weiterhin strömungsgünstig geformt. Er besitzt hierzu die oben bereits erwähnte Luftleitfläche 19. Er ist insbesondere als Strömungskörper geformt, der die von unten austretende Luftströmung verlustarm zur Seite ablenkt. Dies wird mit den in der Figur 5 dargestellten Pfeilen verdeutlicht. Dies führt zu einer Verminderung des Energiebedarfs und der Geräuschentwicklung im Lüftungsstrang. Alle Sichtteile des erfindungsgemäßen Dachlüfters sind aus Ton gefertigt. Beim Kappenträger 12 handelt es sich bevorzugt um eine reine Innenkonstruktion, die, da sie nicht sichtbar ist, auch farblich nicht an die Tonteile angepasst werden muss. Der Dachlüfter kann an Küchenabzügen oder anderweitigen Hauslüftungsanlagen angeschlossen werden.It is considered advantageous that the clay cap does not have to be glued to the tube made of clay. It can be used a plastic intermediate part in the form of the cap carrier 12, which has a maximum ventilation cross-section in the region of the ventilation zone 14. The substructure made of plastic is via positive locking means with the roofing plate 1 connected. It is preferably a detachable anchoring. The positive connection is preferably made via the threaded rods 21. This makes it possible to secure the cap 8 via a screw on the roofing plate 1. A disassembly of the cap 8 for inspection purposes is possible. But adapter 22 and connecting tube 25 may also be in one piece. Again FIG. 7 can be seen, the adapter 22 forms a step on which the lower edge 7 of the ventilation tube 3 can be supported. At the lowest point of this stage, there is an opening 29 in a corner region. A total of two passage openings 29 are provided, through which any accumulating condensation on a roof underlay extends, which extends on the roof inside side of the roofing plate 1. The cap carrier 12 allows by its realization the realization of comparatively large flow cross-sections through the central portion 14. The cap carrier 12 is further formed streamlined. He has for this purpose the above-mentioned air duct 19. He is shaped in particular as a flow body which deflects the low-flow air flowing from the bottom side with little loss. This will be with the in the FIG. 5 illustrated arrows clarifies. This leads to a reduction in energy consumption and noise in the ventilation system. All visible parts of the roof ventilator according to the invention are made of clay. The cap carrier 12 is preferably a pure internal construction, which, since it is not visible, also does not have to be adapted to the color parts in terms of color. The roof vent can be connected to kitchen hoods or other home ventilation systems.

Die außenliegenden Sichtteile können nicht nur aus einem keramischen Material, wie Ton gefertigt sein. Die außenliegenden Sichtteile können aber auch aus anderen Materialien, wie Beton, Faserzement oder Gießbeton hergestellt werden.The outer visible parts can not only be made of a ceramic material, such as clay. The outer visible parts can also be made other materials, such as concrete, fiber cement or cast concrete.

Im Ausführungsbeispiel wird ein Kappenträger 12 aus Kunststoff beschrieben. Der Kappenträger 12 kann aber auch aus Metall oder einem anderen Werkstoff gefertigt sein. Die Montage erfolgt bevorzugt ohne Klebeverbindung und damit ohne Trockenzeit.In the embodiment, a cap carrier 12 is described from plastic. But the cap carrier 12 may also be made of metal or another material. The assembly is preferably without adhesive connection and thus without drying time.
