The weather-protection door has an upper (1) and a lower (2) horizontal door frame component which can be swung open outwards about vertical axes (3) in the housing frame (4-7) surrounding the air inlet orifice. Arranged between the two horizontal door frame components (1, 2), there are vertically extending lamina-like droplet collector sections (8) located next to one another which have a profile bending directed laterally in the same direction between the outside and the inside of the door. The height of the bending is at least as large in the horizontal direction as the horizontal inner diameter of the air vents between the droplet collector sections. The lower horizontal door frame component (2) is provided with a water outlet on the air vents. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Wetterschutztüre für die Lufteinlaßöffnung von Lüftungsanlagen gemaß dem Oberbegriff des Anspruchs 1.The invention relates to a weather protection door for the air inlet opening of ventilation systems according to the preamble of claim 1.

Eine Wetterschutztüre dieser Art ist aus der GB-A-1 363 094 bekannt. Ein fest in eine Wandöffnung eingesetztes Wetterschutzgitter, bei dem vertikal verlaufende Tropfenabscheiderprofile einen gekrümmten Profilverlauf zwischen der Außenseite und der Innenseite des Wetterschutzgitters haben, ist aus der US-A-3 771 430 bekannt.A weather protection door of this type is known from GB-A-1 363 094. A weather protection grille which is firmly inserted into a wall opening and in which vertically running droplet separator profiles have a curved profile profile between the outside and the inside of the weather protection grille is known from US Pat. No. 3,771,430.

Bei Lüftungsanlagen mit einem den Wettereinwirkungen ausgesetzten Lufteinlaß, z. B. bei den auf Gebäudedächern aufgestellten Dachlüftungsgeräten, muß das inder Lufteinlaßöffnung angeordnete, den Durchtritt von Regen verhindernde Wetterschutzgitter oftmals als Türe ausgebildet werden, um durch die Lufteinlaßöffnung einen Zugang für Wartungsarbeiten an den Lüftungsanlagenkomponenten, wie z. B. Filter, Klappen, Gebläse oder Stellmotore und dergleichen, zu ermöglichen. Durch die immer kompakter werdende Bauweise der Lüftungsgeräte ergeben sich erhöhte Anforderungen an solche regendichte Wetterschutztüren für Lufteinlässe. Die bislang gebräuchlichen Wetterschutztüren, die mit dem herkömmlichen jalousieartigen Wetterschutzgitter aus horizontalen Abscheidelamellen ausgebildet sind und dementsprechend an den Türrändern mit Türspaltdichtungen gegenüber dem die Lufteinlaßöffnung umgebenden Einbaurahmen abgedichtet werden, erfüllen die erhöhten Anforderungen nicht. Der Raum, der bei diesen herkömmlichen Wetterschutztüren für die hinter der Türe im Inntern des Lüftungsgerätes liegende Wasserauffangwannen benötigt wird, ist in den meisten Fällen bei den kompakter werdenden Lüftungsgeräten nicht vorhanden. Der auf der Innenseite des Lufteinlasses herrschende Unterdruck erhöht zusätzlich die Anforderungen an die regenundurchlässige Ausbildung und Abdichtung der Wetterschutztüren für die Lufteinlässe von Lüftungsanlagen.In ventilation systems with an air inlet exposed to the weather, e.g. B. in the roof ventilators installed on building roofs, the arranged in the air inlet opening, preventing the passage of rain weather protection grille must often be designed as a door to through the air inlet opening access for maintenance work on the ventilation system components, such as. B. filters, flaps, blowers or actuators and the like. Due to the ever more compact design of the ventilation units, there are increased demands on such rainproof weather protection doors for air intakes. The previously used weather protection doors, which are formed with the conventional blind-like weather protection grille from horizontal separating lamellae and are accordingly sealed at the door edges with door gap seals against the installation frame surrounding the air inlet opening, do not meet the increased requirements. The space for these conventional weather protection doors for those behind the Doors in the interior of the ventilation unit require water collecting trays, is not available in most cases with the increasingly compact ventilation units. The negative pressure prevailing on the inside of the air inlet additionally increases the requirements for the rainproof design and sealing of the weather protection doors for the air inlets of ventilation systems.

Die Erfindung hat zur Aufgabe, vor allem für den Lufteinlaß von solchen Lüftungsanlagen, bei denen aufgrund der kompakten Bauweise der Lufteinlaß und die Lüftungsanlagenkomponenten eng beieinander liegen und die in Verbindung mit den herkömmlichen Wetterschutzgittern hinter der Türe vorgesehenen Wasserauffangwannen aus Platzgründen nicht angewendet werden können, eine Wetterschutztüre zu schaffen, die bei jeder vorkommenden Windrichtung, auch bei starken Regenfällen mit Windböen oder Windwirbeln, zuverlässig und sicher das Regenwasser aus der von der Lüftungsanlage angesaugten Luft abscheidet bei trotzdem nur kleinem Strömungswiderstand für die hindurchtretende Luftströmung, und die auch ohne die bei den herkömmlichen Wetterschutztüren zum Abdichten der Türränder gegenüber dem die Lufteinlaßöffnung umgebenden Einbaurahmen benötigten Türdichtungen z. B. in Form von elastischen Gummidichtungsprofilen ein Hindurchdringen von Regenwasser durch die Trennstelle zwischen Türe und Einbaurahmen zuverlässig unterbindet.The invention has for its object, especially for the air intake of such ventilation systems, in which due to the compact design of the air inlet and the ventilation system components are close together and the provided in connection with the conventional weather protection grilles behind the door can not be used due to space reasons To create weather protection doors that reliably and safely separate the rainwater from the air sucked in by the ventilation system in any wind direction, even in heavy rainfalls with gusts of wind or whirlwinds, with only a small flow resistance for the air flow passing through, and even without the conventional ones Weatherproof doors for sealing the door edges with respect to the installation frame surrounding the air inlet opening required door seals z. B. reliably prevents penetration of rainwater through the separation point between the door and the mounting frame in the form of elastic rubber sealing profiles.

Diese Aufgabe wird gemäß der Erfindung durch die im kennzeichnenden Teil des Anspruchs 1 enthaltenen Merkmale gelöst. Durch die Verwendung der vertikalen Tropfenabscheiderprofile als Wetterschutztüre ist sichergestellt, daß auch bei hohen Abscheideleistungen das abgeschiedene Wasser an jedem Tropfenabscheiderprofil direkt vertikal zum Wasserablaß der Türe abgeleitet wird, und die Profilform bzw. Profilkrümmung der Tropfenabscheiderprofile kann so gewählt werden, daß selbst die ungünstigsten Windrichtungen keinen Einfluß auf die Vollständigkeit und Zuverlässigkeit der Abscheideleistung haben. Mit den im Anspruch 1 angegebenen weiteren Ausgestaltungsmaßnahmen gemäß der Erfindung kann sichergestellt werden, daß ohne eine dicht schließende Berührung zwischen der Türe und dem die Lufteinlaßöffnung enthaltenden Einbaurahmen kein Regenwasser an den beiden vertikalen und an den beiden horizontalen Türrändern hindurchdringt. Die Erfindung wird anhand der Zeichnung näher beschrieben, in der ein bevorzugtes Ausführungsbeispiel der erfindungsgemäßen Wetterschutztüre dargestellt ist. Es zeigen

  • Figur 2 in perspektivischer Darstellung einen vertikalen Schnitt nach der Linie II-II in Figur 1;

This object is achieved according to the invention by the features contained in the characterizing part of claim 1. The use of the vertical droplet separator profiles as a weather protection door ensures that the separated water at each droplet separator profile is drained directly vertically to the water drainage of the door, even with high separating capacities and the profile shape or profile curvature of the droplet separator profiles can be chosen so that even the most unfavorable wind directions have no influence on the completeness and reliability of the separation performance. With the further design measures specified in claim 1 according to Invention can be ensured that without a tightly fitting contact between the door and the mounting frame containing the air inlet opening, no rain water penetrates through the two vertical and on the two horizontal door edges. The invention is described in more detail with reference to the drawing, in which a preferred embodiment of the weather protection door according to the invention is shown. Show it
  • Figure 1 is a perspective view of the weather protection door in the air inlet opening surrounded by a housing frame of the ventilation system;
  • Figure 2 is a perspective view of a vertical section along the line II-II in Figure 1;

Jeder Türflügel der beim dargestellten Ausführungsbeispiel zweiflügeligen Wetterschutztüre besteht aus einem oberen horizontalen Türrahmenteil 1 und einem unteren horizontalen Türrahmenteil 2. Die horizontalen Türrahmenteile 1 und 2 sind um vertikale Türscharnierbolzen 3 in einem die Lufteinlaßöffnung umgebenden Gehäuserahmen, der sich aus den beiden horizontalen Gehäuserahmenteilen 4 und 5 und den beiden senkrechten Gehäuserahmenteilen 6 und 7 zusammensetzt, nach außen aufschwenkbar. Zwischen den beiden horizontalen Türrahmenteilen 1 und 2 besteht die Wetterschutztüre aus vertikal verlaufenden und lamellenartig nebeneinander stehenden Tropfenabscheiderprofilen 8. Diese Tropfenabscheiderprofile 8 sind zwischen der Türaußenseite und der Türinnenseite mit einer gleichsinnig seitwärts gerichteten Profilkrümmung ausgebildet. Die Profilkrümmung hat in horizontaler Richtung eine Krümmungshöhe, die wenigstens so groß ist wie die horizontale lichte Weite der Luftdurchlässe zwischen den Tropfenabscheiderprofilen, so daß in jeder Windrichtung, in der auch im ungünstigsten Fall Wassertropfen an der Türaußenseite in die Luftdurchlässe eintreten, die Wassertropfen von den Tropfenabscheiderprofilen aufgefangen und abgeschieden werden und nicht an der Türinnenseite aus den Luftdurchlässen austreten können. In besonders bevorzugter Weise bestehen die Tropfenabscheiderprofile nicht nur aus einem zwischen seinen beiden Längsrändern bogenförmig oder in anderer gleichwirkender Form gekrümmten Lamellenstreifen, sondern sind die Tropfenabscheiderprofile 8 im Anschluß an ihren zur Türaußenseite weisenden Profilrand zunächst mit einem im wesentlichen rechtwinkelig zur Türebene stehenden, ebenflächigen Profilwandungsteil 9 ausgebildet, mit dem benachbarte Tropfenabscheiderprofile eine gerade Beruhigungsstrecke des Luftdurchlasses bilden und an den sich dann in Richtung zur Türinnenseite hin der die Profilkrümmung aufweisende Wandungsteil des Tropfenabscheiderprofils anschließt. Vorzugsweise läuft dieser die Profilkrümmung aufweisende Profilwandungsteil auch wieder mit einem rechtwinkelig zur Türebene stehenden und ebenflächigen Profilrandstreifen 10 zur Türinnenseite aus. Durch diese Profilform werden mit Regen in die Luftdurchlässe eintretende Luftströmungen zunächst beruhigt, um dadurch die Zuverlässigkeit und Wirksamkeit der Wassertropfenabscheidung an den Profilkrümmungen der Tropfenabscheiderprofile noch weiter zu erhöhen. In weiterer vorteilhafter Ausgestaltung besitzen die Tropfenabscheiderprofile an der höchsten Stelle ihrer konvexen Profilkrümmung und vorzugsweise auch an dem zur Türinnenseite weisenden Ende ihrer konkaven Profilkrümmung eine vertikal verlaufende Lippe 11, die in den Luftdurchlaß vorspringt und eine zur Türaußenseite U-förmig offene vertikale Abscheiderinne bildet. Diese Abscheiderinnen verhindern, daß Wassertropfen nach der Abscheidung an der vor der Lippe 11 liegenden Profilkrümmung auf der Oberfläche der Tropfenabscheiderprofile zum türinnenseitigen Profilrand fließen. Die Tropfenabscheiderprofile 8 können eingebaute Heizdrähte einer Enteisungsheizung enthalten und z. B. aus Aluminium als gutem Wärmeleiter bestehen, um dadurch im Winter sicherzustellen, daß die von den Lippen 11 gebildeten Abscheiderinnen eis- und schneefrei bleiben.Each door leaf of the two-leaf weather protection door in the illustrated embodiment consists of an upper horizontal door frame part 1 and a lower horizontal door frame part 2. The horizontal door frame parts 1 and 2 are around vertical door hinge bolts 3 in a housing frame surrounding the air inlet opening, which consists of the two horizontal housing frame parts 4 and 5 and the two vertical housing frame parts 6 and 7, pivoted outwards. Between the two horizontal door frame parts 1 and 2, the weather protection door consists of vertically running and lamella-like droplet separator profiles 8. These droplet separator profiles 8 are formed between the outside of the door and the inside of the door with a profile curvature which is directed sideways in the same direction. The profile curvature has a height of curvature in the horizontal direction that is at least as large as the horizontal clear width of the air passages between the droplet separator profiles, so that in every wind direction, in the worst case, water drops on the outside of the door enter the air passages, the water drops from the Mist eliminator profiles collected and separated and cannot escape from the air outlets on the inside of the door. In a particularly preferred manner, the droplet separator profiles not only consist of a strip of lamella curved between its two longitudinal edges or in another form having the same effect, but are the droplet separator profiles 8 following their profile edge pointing towards the outside of the door, initially with a flat profile wall part 9 which is essentially at right angles to the door plane formed with which adjacent droplet separator profiles form a straight calming section of the air passage and then adjoins the wall part of the droplet separator profile having the profile curvature in the direction of the inside of the door. This profile wall part, which has the profile curvature, preferably also runs out again with a profile edge strip 10, which is at right angles to the door plane, and runs to the inside of the door. With this profile shape, air flows entering the air passages are initially calmed down in order to further increase the reliability and effectiveness of the water droplet separation at the profile curvatures of the droplet separator profiles. In a further advantageous embodiment, the droplet separator profiles have a vertically extending lip 11 at the highest point of their convex profile curvature and preferably also at the end of their concave profile curvature pointing towards the inside of the door, which protrudes into the air passage and forms a vertical separating channel which is open in a U-shape to the outside of the door. These separators prevent water drops from flowing after the separation on the profile curvature lying in front of the lip 11 on the surface of the drop separator profiles to the profile edge on the inside of the door. The droplet separator profiles 8 can contain built-in heating wires of a deicing heater and, for. B. made of aluminum as a good heat conductor, thereby ensuring in winter that the separators formed by the lips 11 remain free of ice and snow.

Die regenundurchlässige, besondere Türdichtungen im Türspalt vermeidende Ausbildung der senkrechten Trennstellen zwischen der Wetterschutztüre und dem die Lufteinlaßöffnung umgebenden Gehäuserahmen besteht erfindungsgemäß darin, daß an den beiden senkrechten Gehäuserahmenteilen 6, 7 ein feststehendes Tropfenabscheiderprofil 12 angeordnet ist, das in der Profilkrümmung zu den Tropfenabscheiderprofilen 8 der Türe paßt und mit dem benachbarten, den senkrechten Türrand bildenden Tropfenabscheiderprofil der Türe einen Luftdurchlaß als Türspalt bildet, der in der gleichen Weise regenundurchlässig ist wie die Luftdurchlässe, die die Tropfenabscheiderprofile 8 der Türe zwischen sich selber bilden. Ebenso wie die Luftdurchlässe der Türe steht auch der Luftdurchlaß zwischen dem feststehenden Tropfenabscheiderprofil 12 des Gehäuserahmens und dem benachbarten Tropfenabscheiderprofil 8 der Türe mit einem Wasserablauf in Verbindung, der noch näher beschrieben wird. An dem die Türscharniere enthaltenden senkrechten Türrand verschwenken sich beim Öffnen bzw. Schließen der Türe die beiden benachbarten Profile 12 und 8 um die Türscharnierachse 3 auseinander bzw. ineinander. An dem ausschwenkenden anderen senkrechten Türrand können die beiden analogen benachbarten Tropfenabscheiderprofile in einfacher Weise dadurch beim Öffnen bzw. Schließen der Türe aneinander vorbeigebracht werden, daß die Türe, wie das dargestellte Ausführungsbeispiel zeigt, zweiflügelig ist und die beiden Türflügel an ihren gegenüberstehenden senkrechten Rändern zusammenwirkende Tropfenabscheiderprofile 8 besitzen und gleichzeitig aus der geschlossenen Stellung geöffnet werden bzw. in die geschlossene Stellung zurückgeschwenkt werden.The rainproof, special door seals in the According to the invention, the formation of the vertical separation points between the weather protection door and the housing frame surrounding the air inlet opening to avoid door gaps consists in that a fixed drop separator profile 12 is arranged on the two vertical housing frame parts 6, which fits in the profile curvature to the drop separator profiles 8 of the door and with the neighboring one , the vertical door edge forming droplet separator profile of the door forms an air passage as a door gap, which is impermeable to rain in the same way as the air passages that form the droplet separator profiles 8 of the door between themselves. Just like the air passages of the door, the air passage between the fixed droplet separator profile 12 of the housing frame and the adjacent droplet separator profile 8 of the door is connected to a water drain, which will be described in more detail. On the vertical door edge containing the door hinges, the two adjacent profiles 12 and 8 pivot apart or into one another about the door hinge axis 3 when the door is opened or closed. At the swinging out other vertical door edge, the two similar adjacent droplet separator profiles can be brought past one another in a simple manner when opening or closing the door, that the door, as the illustrated embodiment shows, has two leaves and the two door leaves interacting drop separator profiles on their opposite vertical edges 8 have and at the same time be opened from the closed position or pivoted back into the closed position.

Die regenundurchlässige, besondere Türdichtungen im Türspalt vermeidende Ausbildung der horizontalen Trennstellen zwischen der Wetterschutztüre und dem Gehäuserahmen besteht erfindungsgemäß darin, daß der untere horizontale Gehäuserahmenteil 5 aus einem im wesentlichen U-förmig nach oben offenen Hohlprofil und der obere horizontale Gehäuserahmenteil 4 aus einem im wesentlichen U-förmig nach unten offenen Hohlprofil bestehen. Das untere Rahmenhohlprofil 5 besitzt eine türaußenseitige Profilwand 13, über der der untere Türrahmenteil 2 aus der Lufteinlaßöffnung herausschwenkbar ist und die mit diesem unteren Türrahmenteil 2, vorzugsweise über einen etwa umgekehrt U-förmig abgewinkelten Rand 14 der Profilwand 13, einen verengten Türspalt bildet. Der Profilboden 15 des unteren Rahmenhohlprofils 5 bildet sodann mit dem unteren Türrahmenteil 2 einen breiten Zwischenraum, der sich an den verengten Türspalt anschließt und in dem sich die durch den verengten Türspalt eintretende Luftströmung derart beruhigt, daß von der eintretenden Luftströmung mitgeführte Wassertropfen zum Boden des direkt als Auffangwanne ausgebildeten und dienenden unteren Rahmenhohlprofils 5 herunterfallen und aus der Luft abgeschieden werden und nicht zu der Trennstelle zwischen dem unteren Türrahmenteil 2 und der türinnenseitigen Profilwand 16 des unteren Rahmenhohlprofils 5 gelangen. Die türinnenseitige Profilwand 16 des unteren Rahmenhohlprofils 5 überlappt zweckmäßigerweise in der Höhe den unteren Türrahmenteil 2, um einen Türanschlag für den einwärts verschwenkten unteren Türrahmenteil zu bilden. In den von dem unteren Rahmenhohlprofil 5 gebildeten Wasserauffang-Zwischenraum mündet der Wasserablaß aus, durch den das an den Tropfenabscheiderprofilen der Türe und den feststehenden Tropfenabscheiderprofilen des Gehäuserahmens abgeschiedene und nach unten ablaufende Wasser abfließt. Das obere horizontale Rahmenhohlprofil 4 besitzt in analoger Weise eine türaußenseitige Profilwand 17, die mit dem oberen Türrahmenteil 1 einen verengten Türspalt bildet, eine türinnenseitige Profilwand 18, die einen Türanschlag für den einwärts verschwenkten oberen Türrahmenteil 1 bildet, und einen Profilboden 19, der mit dem oberen Türrahmenteil 1 einen an den verengten Türspalt sich anschließenden breiten, die eintretende Luftströmung beruhigenden Zwischenraum bildet. Auch in diesem Zwischenraum tritt eine solche Beruhigung der an der türaußenseitigen Profilwand 17 durch den verengten Türspalt eintretenden Luftströmung ein, daß mitgeführte Wassertropfen auf die Oberseite des oberen Türrahmenteils herunterfallen und abgeschieden werden und auf keinen Fall mehr von der Luft bis zu der Trennstelle zwischen der türinnenseitigen Profilwand 18 und dem Türrahmenteil 1 mitgeführt werden. Der obere Türrahmenteil 1 ist mit Wasserdurchlässen 20 in Form von Längsschlitzen versehen, durch die das auf der Oberseite des oberen horizontalen Türrahmenteils 1 sich ansammelnde, abgeschiedene Wasser zu den Luftdurchlässen zwischen den Tropfenabscheiderprofilen 8 der Türe hindurchfließen kann, um sodann an den Tropfenabscheiderprofilen bis in die Auffangwanne des unteren Rahmenhohlprofils 5 abzufließen. Der untere horizontale Türrahmenteil 2 kann als Wasserablaß ähnliche Längsschlitze aufweisen, durch die das an den Tropfenabscheiderprofilen herunterfließende Wasser in das untere Rahmenhohlprofil 5 abfließt.The rainproof, special door seals in the door gap avoiding the formation of the horizontal separation points between the weather protection door and the housing frame according to the invention consists in that the lower horizontal housing frame part 5 consists of a substantially U-shaped upward open hollow profile and the upper horizontal housing frame part 4 from a substantially U. -have a hollow profile open at the bottom. The lower frame hollow profile 5 has a door-outside profile wall 13, via which the lower door frame part 2 can be pivoted out of the air inlet opening and which forms a narrowed door gap with this lower door frame part 2, preferably via an edge 14 of the profile wall 13, which is angled in an approximately U-shaped manner. The profile floor 15 of the lower hollow frame section 5 then forms a wide space with the lower door frame part 2, which adjoins the narrowed door gap and in which the air flow entering through the narrowed door gap calms down in such a way that water drops carried along by the incoming air flow to the floor of the direct formed as a collecting pan and serving lower frame hollow section 5 and are separated from the air and do not reach the separation point between the lower door frame part 2 and the inside wall 16 of the lower frame hollow section 5. The inside wall of the profile wall 16 of the lower hollow frame section 5 expediently overlaps in height the lower door frame part 2 in order to form a door stop for the inwardly pivoted lower door frame part. In the water catchment space formed by the lower frame hollow profile 5, the water outlet opens out, through which the water separated on the droplet separator profiles of the door and the fixed droplet separator profiles of the housing frame and drains down. The upper horizontal frame hollow profile 4 has in an analogous manner a profile wall 17 on the outside of the door, which forms a narrowed door gap with the upper door frame part 1, a profile wall 18 on the inside of the door, which forms a door stop for the inwardly pivoted upper door frame part 1, and a profile floor 19, which with the Upper door frame part 1 forms a wide space adjoining the narrowed door gap and calming the incoming air flow. Also in this space occurs such a calming of the air flow entering the outside profile wall 17 through the narrowed door gap that water droplets entrained on the The top of the upper door frame part should fall down and be separated and in no case be carried along from the air to the point of separation between the inside wall 18 of the profile and the door frame part 1. The upper door frame part 1 is provided with water passages 20 in the form of longitudinal slots through which the separated water accumulating on the upper side of the upper horizontal door frame part 1 can flow to the air passages between the droplet separator profiles 8 of the door, in order then to pass through the droplet separator profiles Drain the drain pan of the lower hollow frame section 5. The lower horizontal door frame part 2 can have similar longitudinal slots as a water outlet through which the water flowing down the droplet separator profiles flows into the lower hollow frame profile 5.
