Description

Die Erfindung betrifft eine Ventilationseinheit für einen Lüftungsschacht.The invention relates to a ventilation unit for a Ventilation shaft.

Zur Vermeidung von Wärmeverlusten werden vor allem unter Berücksichtigung der Vorschriften von Wärmeschutzverordnungen insbesondere Wohnhäuser immer mehr gegen durchströmende Zugluft abgedichtet. Dennoch muß eine ausreichende Belüftung sichergestellt sein, wozu in den meisten Fällen ein vollständiger Luftaustausch innerhalb von zwei Stunden für einen Wohnraum ausreicht. Zur Entlüftung wird ein vertikaler Schacht vorgesehen in dem sich ein die Abluft führendes Innenrohr angeordnet ist. Wenn der natürliche Luftzug nicht ausreicht, so ist ein Ventilator erforderlich, der vorteilhafterweise im Bereich des Dachraumes eines Hauses installiert wird.To avoid heat loss, especially under Taking into account the regulations of thermal insulation regulations residential buildings in particular are increasingly combating Drafts sealed. However, adequate ventilation is required be sure what to do in most cases full air exchange within two hours for a living space is sufficient. A vertical is used for ventilation Shaft provided in which there is an exhaust air duct Inner tube is arranged. If the natural draft is not is sufficient, a fan is required that advantageously in the area of the roof space of a house is installed.

Derartige Ventilatoren sind handelsüblich, müssen jedoch gesondert montiert werde, wozu entsprechende individuell angefertigte Befestigungsteile erforderlich sind. Insbesondere in den Nachtstunden werden die Geräusche des Ventilators als störend empfunden.Such fans are commercially available, but must be assembled separately, for which purpose individually made fasteners are required. In particular in the night hours the noise of the fan is considered felt annoying.

Der vorliegenden Erfindung liegt das Problem zugrunde, für ein Lüftungssystem zur zentralen Entlüftung eines Wohnhauses eine Ventilationseinheit zur Verfügung zu stellen, die komplett vormontiert ist, störenden Lärm vermeidet und auf der Baustelle schnell von ungeübten Kräften auf ein Schachtsystem aufgesetzt werden kann.The present invention addresses the problem for a Ventilation system for the central ventilation of a residential building Ventilation unit to provide that complete is pre-assembled, avoids annoying noise and on the Construction site quickly by inexperienced people on a shaft system can be put on.

Das Problem wird dadurch gelöst, daß die Ventilationseinheit eine tragfähiges Gehäuse besitzt, in dem ein Ventilator schall- und wärmeisoliert fixiert ist, daß an der Unterseite des Gehäuses eine Ansaugöffnung für die anzusaugende Luft und an der Oberseite des Gehäuses eine Austrittsöffnung für die abzuführende Luft vorgesehen ist.The problem is solved in that the ventilation unit has a load-bearing housing in which a fan sound and heat insulated that is fixed on the bottom the housing a suction opening for the air to be sucked in at the top of the housing an outlet for the air to be discharged is provided.

Die Ventilationseinheit kann als Fertigteil angeliefert werden und erfordert nach dem Aufsetzen auf den Lüftungsschacht außer dem elektrischen Anschluß des Ventilators und dem Anschluß der Austrittsöffnung an eine Abluftleitung keine zusätzlichen Arbeiten.The ventilation unit can be delivered as a finished part and requires after placing on the ventilation shaft except the electrical connection of the fan and the connection of the Outlet opening to an exhaust air duct no additional Work.

Die Abführung der Abluft kann durch einen handelsüblichen Dachdurchgang mit Dunstrohr erfolgen. Während für die Lage des vertikalen Lüftungsschachtes und damit für die Lage der Austrittsöffnung der Ventilationseinheit bauliche Gegebenheiten maßgebend sind, ist die Lage des Dachdurchgangs bei einem Schrägdach von der Position der Dachsparren und der Dachlatten abhängig. Ein Achsenversatz zwischen Austrittsöffnung und Dachdurchgang wird in einfacher Weise dadurch ausgeglichen, daß die Verbindung des Dachdurchgangs mit der Austrittsöffnung mittels eines flexiblen Schlauchs erfolgt.The exhaust air can be removed by a commercially available Roof passage with smoke pipe. While for the location of the vertical ventilation shaft and thus for the location of the Constructional outlet opening of the ventilation unit The decisive factors are the position of the roof passage with a pitched roof from the position of the rafters and the Roof battens dependent. An axis offset between The outlet opening and roof passage is easy compensated for in that the connection of the roof passage with the outlet opening using a flexible hose he follows.

Das tragfähiges Gehäuse der Ventilationseinheit nimmt Quer- und Gewichtskräfte auf, wenn beispielsweise eine lange Abluftleitung an die Ventilationseinheit angeschlossen werden muß.The load-bearing housing of the ventilation unit and weight forces when, for example, a long one Exhaust air line can be connected to the ventilation unit got to.

Insbesondere bei Einsatz der Ventilationseinheit auf einem Schachtsystem mit rotationssymmetrischer äußerer Querschnittsform ist es vorteilhaft, wenn auch das Gehäuse eine rotationssymmetrische äußere Querschnittsform aufweist. Als rotationssymmetrische Querschnittsform kommt eine runde, eine acht- oder sechseckige oder eine quadratische Form in Frage. Bevorzugt wird eine quadratische Querschnittsform.Especially when using the ventilation unit on one Shaft system with rotationally symmetrical outer Cross-sectional shape, it is advantageous if also the housing has a rotationally symmetrical outer cross-sectional shape. As a rotationally symmetrical cross-sectional shape, a round, an octagonal or hexagonal or a square shape in Question. A square cross-sectional shape is preferred.

Eine einfache Befestigung des Ventilators im Gehäuse wird durch Formteile aus schall- und wärmeisolierendem Werkstoff erreicht. Die Wärmeisolation verhindert die Abscheidung von Kondenswasser am bzw. im Ventilator, so daß keine Vorkehrungen zur Wasserabführung erforderlich sind.The fan is simply attached to the housing through molded parts made of sound and heat insulating material reached. The thermal insulation prevents the separation of Condensation on or in the fan, so that no precautions are necessary for water drainage.

Eine bequeme Zugänglichkeit zum Ventilator, beispielsweise zum elektrischen Anschluß oder zur Wartung, ist gegeben, wenn zumindest das den Ventilator seitlich umgebende Formteil zweiteilig ausgeführt ist, wobei eines der Formteile durch eine Öffnung in der Seitenwand des Gehäuses entfernbar ist. Vorzugsweise werden die seitlichen Formteile als symmetrische Hälften mit parallel zur Achse verlaufenden Trennebenen ausgeführt. Die Öffnung in der Seitenwand kann durch eine Türe oder ein Abdeckblech verschließbar sein.Easy access to the fan, for example electrical connection or for maintenance, is given if at least the molded part laterally surrounding the fan is designed in two parts, one of the molded parts by an opening in the side wall of the housing is removable. Preferably, the side moldings are considered symmetrical Halves with parting planes running parallel to the axis executed. The opening in the side wall can be through a door or a cover plate can be closed.

Der dichte Anschluß der Ventilationseinheit an einen Lüftungsschacht ist besonders einfach, wenn die Ansaugöffnung in einem aus Unterseite des Gehäuses herausragenden Rohrstutzen angeordnet ist. Der Rohrstutzen kann von oben in das Innenrohr des Lüftungsschachtes eingesteckt werden und mit einer kreisringförmigen Lippendichtung gegen das Eindringen von Falschluft abgedichtet werden.The tight connection of the ventilation unit to one Ventilation duct is particularly simple when the intake opening in a protruding from the bottom of the case Pipe socket is arranged. The pipe socket can be in from above the inner tube of the ventilation shaft can be inserted and with an annular lip seal to prevent penetration be sealed by false air.

Ein Auswechseln des Ventilators nach längerer Betriebszeit ist möglich, wenn der Ansaugstutzen des Ventilators in den Rohrstutzen eingesteckt ist, und daß der Austrittsstutzen des Ventilators mit dem Anschluß für die abzuführende Luft durch eine längenveränderbare Leitung verbunden ist. Als längenveränderbare Leitung kann beispielsweise ein Faltenbalg oder ein Wellschlauch vorgesehen sein.The fan must be replaced after a long period of operation possible if the intake of the fan in the Pipe socket is inserted, and that the outlet of the Fan with the connection for the air to be discharged a variable-length line is connected. As length-adjustable line can be, for example, a bellows or a corrugated hose can be provided.

Nach Abnahme der einen Hälfte der seitlichen Formteile kann der Ventilator nach oben zum Anschluß für die abzuführende Luft angehoben werden, wobei die längenveränderbare Leitung zusammengedrückt wird, bis der Ansaugstutzen des Ventilators aus dem unten befindlichen Rohrstutzen austritt. Wird nunmehr die längenveränderbare Leitung weiter zusammengedrückt, bis der Ansaugstutzen des Ventilators frei ist, so kann der Ventilator durch Öffnung in der Seitenwand des Gehäuses entfernt werden. Der Einbau eines neuen Ventilators erfolgt in umgekehrter Reihenfolge.After removing half of the side moldings you can the fan up to the connection for the to be discharged Air can be raised, using the length-adjustable line is compressed until the intake manifold of the fan emerges from the pipe socket below. Will now the length-adjustable line is further compressed until the intake manifold of the fan is free, so the Fan through opening in the side wall of the housing be removed. A new fan is installed in reverse order.
