Abstract

The ventilator incorporates an open housing with a baffle wall ceiling (5). Several driven rain protection covers (9) are located to the side of the ceiling. In open position, the covers form guide walls for the outflowing air. The journal pins (8) of the covers are located in a plane, which is slightly inclined relative to the baffle ceiling. The rain protection covers are double-armed and slightly curved.

Description

Die Erfindung betrifft einen Dachflächenentlüfter nach dem Oberbegriff des Anspruches 1 (Siehe z.B. CH-A-637 754 und DE-U-1 849 839).The invention relates to a roof vent according to the preamble of claim 1 (see e.g. CH-A-637 754 and DE-U-1 849 839).

Bei Betrieben mit wärmeintensiver Technologie ist eine besonders hochentwickelte und dem Umweltklima angepaßte Lüftungstechnik erforderlich. Bei solchen Betrieben werden große Konvektions- und Strahlungswärmeströme an die Umgebung abgegeben. Zur Abfuhr dieser Wärme sind große Luftmassenströme erforderlich, um optimale mikroklimatische Bedingungen zu gewährleisten. Man bedient sich dabei der thermodynamischen Lüftung.Companies with heat-intensive technology require particularly sophisticated ventilation technology that is adapted to the environmental climate. In such operations, large convection and radiant heat flows are emitted to the environment. Large air mass flows are required to dissipate this heat in order to ensure optimal microclimate conditions. Thereby, thermodynamic ventilation is used.

Gerade bei großen Dachöffnungen kommt es einerseits darauf an, die austretenden Abluftströme möglichst laminar zu führen und andererseits dafür Sorge zu tragen, daß bei Regenwetter die Dachöffnungen ausreichend gegen Einregnen gesichert sind.Especially with large roof openings, it is important, on the one hand, to guide the escaping exhaust air flows as laminarly as possible and, on the other hand, to ensure that the roof openings are adequately secured against raining in rainy weather.

Bei bekannten Dachflächenentlüftern sind für die Luftführung in der Regel Register mit starren Leitwänden im Dachflächenentlüftergehäuse vorgesehen, die für eine bestimmte Umweltbedingung eingestellt sind. Sie sind nicht in der Lage, sich den jeweiligen Witterungsverhältnissen anzupassen. Auch sind sie für notwendige Reinigungsarbeiten schwer zugänglich. Ferner sind oberhalb dieser Leitwände Regenabdeckorgane vorgesehen, mit denen ein Einregnen in die Dachflächenentlüfter verhindert werden soll. Da diese meist starr ausgebildet sind, stehen sie der Luftführung hindernd entgegen.In known roof surface ventilators, registers with rigid guide walls are generally provided in the roof surface ventilator housing for the air guidance and are set for a specific environmental condition. They are unable to adapt to the prevailing weather conditions. They are also difficult to access for necessary cleaning work. Furthermore rain cover elements are provided above these guide walls, with which raining into the roof surface ventilators should be prevented. Since these are usually rigid, they prevent airflow.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Dachflächenentlüfter für breite Dachöffnungen so zu verbessern, daß er den unterschiedlichen Witterungen angepaßt werden kann.The present invention has for its object to improve a roof vent for wide roof openings so that it can be adapted to different weather conditions.

Die Lösung der gestellten Aufgabe besteht gemäß der Erfindung in den kennzeichnenden Merkmalen das Anspruches 1. Bei dieser Ausführung übernehmen die Regenverschlußklappen einerseits die bekannte Aufgabe eines Regenverschlußorgans und andererseits diejenige von witterungsgesteuerten Leitwänden für den Abluftstrom.The solution to the problem is according to the invention in the characterizing features of claim 1. In this embodiment, the rain shutters take on the one hand the known task of a rain shutter organ and on the other hand that of weather-controlled guide walls for the exhaust air flow.

Nachstehend ist die Erfindung anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispieles näher erläutert.The invention is explained in more detail below on the basis of an exemplary embodiment shown schematically in the drawing.

Der in der Zeichnung im Querschnitt dargestellte Dachflächenentlüfter für breite Dachöffnungen besteht aus einem Einlaßkanal 1, der mitels Flanschen 2 an einer breiten Dachöffnung 3 befestigt ist und an den ein wesentlich breiteres Gehäuse 4 anschließt.The roof vent, shown in cross section in the drawing, for wide roof openings consists of an inlet duct 1, which is fastened by means of flanges 2 to a wide roof opening 3 and to which a much wider housing 4 connects.

Dieses Gehäuse 4 ist trichterförmig erweitert, oben offen und weist in seiner Mitte, mit Abstand oberhalb der Dachöffnung 3 eine ggf. dachprofilförmige Prallwanddecke 5 auf, die mit seitlichen Regenabflußrinnen 6 ausgerüstet ist.This housing 4 is widened in a funnel shape, open at the top and has in its center, at a distance above the roof opening 3, a baffle wall ceiling 5 which is optionally shaped as a roof profile and which is equipped with lateral rain gutters 6.

Zwischen den seitlichen Rändern dieser Prallwanddecke 5 und dem oberen Rand 7 des Gehäuses 4 sind in einer zur Prallwanddecke 5 leicht geneigten Ebene und koaxial zur Längsachse der Prallwanddecke 5 Zapfen 8 angeordnet, auf denen mehrere mit einem nicht dargestellten Verstellantrieb verbundene und vorzugsweise doppelarmige Regenverschlußklappen 9 angeordnet. Diese sind so bemessen, daß sie sich in geschlossenem Zustand in Richtung zur zugeordneten Regenabflußrinne 6 schindelartig überlappen. Infolge der Anordnung der Zapfen 8 auf einer geneigten Ebene bilden die geschlossenen Regenverschlußklappen 9 ein leichtes Gefälle.Between the side edges of this baffle cover 5 and the upper edge 7 of the housing 4 are in a plane slightly inclined to the baffle cover 5 and Arranged coaxially to the longitudinal axis of the baffle cover 5, pins 8, on which a plurality of preferably double-armed rain shutters 9 connected to an adjustment drive, not shown, are arranged. These are dimensioned such that they overlap like shingles in the closed state in the direction of the assigned rain gutter 6. As a result of the arrangement of the pins 8 on an inclined plane, the closed rain shutters 9 form a slight slope.

Vorteilhaft sind die Regenverschlußklappen 9 leicht gewölbt. Im Betrieb können sie je nach herrschender Witterung eine mehr oder weniger geneigte Stellung einnehmen und stehen dabei im wesentlichen Senkrecht. Bei Regenwetter können sie ganz geschlossen werden.The rain shutters 9 are advantageously slightly curved. Depending on the prevailing weather, they can assume a more or less inclined position in operation and are essentially vertical. They can be closed completely in rainy weather.

Claims (3)

  1. Roof area ventilator for wide roof openings, including an inlet duct, which is mountable on the roof opening, and a housing, which communicates with said duct and is open at its upper end, said housing having a central deflecting wall cover, the width of said deflecting wall cover being at least identical to the width of the inlet duct, characterised in that a plurality of drivable flaps (9), which are closable in the rain, are disposed laterally of the deflecting wall cover (5) and, in their open position, form guide walls for the outgoing air, pins (8) of the rain closure flaps (9) lying on a plane which has a slight downward inclination relative to the deflecting wall cover (5).
  2. Roof area ventilator according to claim 1, characterised in that the closable flaps (9) have a double-armed configuration.
  3. Roof area ventilator according to claim 1 or 2, characterised in that the closable flaps (9) are slightly curved.
