Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Lüften von Räumen, mit einem eine von einem Elektromotor angetriebene Gebläseanordnung aufnehmenden Gehäuse und mit einem das Gehäuse abdeckenden, mit einer Befestigungseinrichtung lösbar am Gehäuse befestigten Gehäusedeckel, an den gegebenenfalls ein Filter und eine Abdeckblende angesetzt sind, wobei die Gebläseanordnung und der Gehäusedeckel eine Baueinheit bilden, die lösbar in das Gehäuse eingesetzt ist.The invention relates to a device for ventilating rooms, with a housing receiving a blower arrangement driven by an electric motor and with a housing cover which covers the housing and is releasably fastened to the housing with a fastening device, to which a filter and a cover plate are optionally attached, whereby the blower arrangement and the housing cover form a structural unit which is detachably inserted into the housing.

Alle bekannten Lüfter für ein Rohrlüftungssystem bestehen aus Gehäuse, Gebläse, Gehäusedeckel zur Aufnahme eines Filters, Filter und Abdeckung. Die Befestigung von Gebläse und Gehäusedeckel im Gehäuse erfolgt übrigens mit Schrauben. Für verschiedene Einbautiefen des Gehäuses in Wänden werden üblicherweise unterschiedlich lange Schrauben verwendet. Diese Art der Montage ist allerdings sehr zeitintensiv und nicht ohne Werkzeug möglich. Da die Befestigung meist mit Schrauben erfolgt und diese beim Manipulationsprozess fallweise auch verloren gehen können ist nicht stets der ordnungsgemäße Zusammenbau gewährleistet. Eine Demontage, gegebenenfalls zu Wartungszwecken erfordert ebenfalls Werkzeuge und ist mit den gleichen Gefahren verbunden. Da in der Praxis üblicherweise unterschiedliche Einbautiefen vorkommen sind zur Überbrückung dieser Einbautiefen unterschiedlichste Schraubenlängen vorzusehen.All known fans for a pipe ventilation system consist of a housing, blower, housing cover for receiving a filter, filter and cover. Incidentally, the fan and the housing cover are fastened in the housing with screws. Screws of different lengths are usually used for different installation depths of the housing in walls. However, this type of assembly is very time-consuming and not possible without tools. Since the fastening is usually done with screws and these can sometimes be lost during the manipulation process, proper assembly is not always guaranteed. Disassembly, possibly for maintenance purposes, also requires tools and is associated with the same dangers. Since different installation depths usually occur in practice, different screw lengths must be provided to bridge these installation depths.

Eine Vorrichtung der eingangs geschilderten Art ist insbesondere aus der DE 37 11 720 A1 bekannt. Dabei wird die Baueinheit zur Montage in das Gehäuse eingeschoben und in der gewünschten Montagelage mittels Klemmkrallen festgelegt, die beim Festlegen mittels einer Klemmschraube hebelkraftbedingt in die Gehäusewandung eindringen.A device of the type described is in particular from the DE 37 11 720 A1 known. The assembly is inserted into the housing for mounting and is fixed in the desired mounting position by means of clamping claws which, when fixed by means of a clamping screw, penetrate into the housing wall due to the lever force.

Bekannte Vorrichtungen, sogenannte Lüftereinheiten, dienen insbesondere zur Entlüftung von Gebäuderäumen ( DE 29623226 U1 , DE 20015136 U1 ). Es soll damit insbesondere aus Sanitärräumen, Küchen und Abstellräumen Schadstoff-, feuchte bzw. geruchsbelastete Luft abgesaugt werden. Die Vorrichtung wird üblicherweise über eine Verbindungsleitung an ein Abluftrohr angeschlossen, welches als zentrales Lüftungsrohr dient und sich in einem Schacht befindet. Dies wird beispielsweise zu einer Entlüftungsöffnung im Dachbereich geführt. In vielen Fällen blasen mehrere Lüfteinheiten in ein gemeinsames Entlüftungsrohr.Known devices, so-called fan units, are used in particular for venting building rooms ( DE 29623226 U1 , DE 20015136 U1 ). It should so that pollutant, moist or odor-laden air is extracted from sanitary rooms, kitchens and storage rooms The device is usually connected via a connecting line to an exhaust pipe, which serves as a central ventilation pipe and is located in a shaft. This leads, for example, to a ventilation opening in the roof area. In many cases, several ventilation units blow into a common ventilation pipe.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Vorrichtung der eingangs geschilderten Art zu schaffen, die eine werkzeuglose Montage mit möglichst wenigen einzelnen Komponenten erlaubt, wobei vorzugsweise unterschiedliche Einbautiefen ohne Verwendung zusätzlicher Teile, wie Schrauben unterschiedlicher Länge, überbrückt werden können.The invention is therefore based on the object of providing a device of the type described at the outset which allows tool-free assembly with as few individual components as possible, preferably different installation depths being able to be bridged without the use of additional parts, such as screws of different lengths.

Die Erfindung löst die gestellte Aufgabe dadurch, dass der Baueinheit wenigstens eine Rastfeder zugeordnet ist, mit der die Baueinheit mit dem Gehäuse verrastbar ist und die an der Baueinheit entlang einer Führung zwischen einer Raststellung und einer Freigabestellung verlagerbar ist.The invention solves the stated problem in that the assembly is assigned at least one detent spring with which the assembly can be locked to the housing and which can be displaced on the assembly along a guide between a detent position and a release position.

Durch diese Maßnahme ist gewährleistet, dass die besagte Baueinheit auch im Gehäuse unterschiedlichster Einbautiefen einsetzbar ist und dabei stets eine ordnungsgemäße Funktion gewährleistet ist, da diese Baueinheit stets die geordnete Zusammenwirkung von Gebläseanordnung und Befestigungsvorrichtung im Gehäuse sicherstellt. Erfindungsgemäß bilden Gebläse und Gehäusedeckel eine Einheit, wobei die Gebläseanordnung vorzugsweise mit mehreren Rastfedern ausgestattet ist, die im Einbauzustand mit dem Gehäuse, insbesondere mit im Gehäuse ausgebildeten Halteelementen, verrasten. Zur Montage wird die Gebläseeinheit mit dem Gehäusedeckel in das Gehäuse eingeschoben. Dabei gleiten die Rastfedern beim Einschieben in das Gehäuse an einem Anschlag vorbei und rasten dahinter entsprechend ein. Der Abdeckrahmen ist größer als die Gebläseeinheit und liegt an der Gehäusewand dichtend an. Die Haltefedern werden beim Hineinschieben vorgespannt und fixieren so die Gebläseeinheit und den Abdeckrahmen in der Einbaulage.This measure ensures that the said assembly can also be used in the housing of the most varied installation depths, and that proper functioning is always guaranteed, since this assembly always ensures the orderly interaction of the blower arrangement and the fastening device in the housing. According to the invention, the blower and the housing cover form a unit, the blower arrangement preferably being equipped with a plurality of latching springs which, when installed, latch with the housing, in particular with holding elements formed in the housing. For assembly, the blower unit with the housing cover is pushed into the housing. The locking springs slide past a stop when inserted into the housing and snap into place accordingly. The cover frame is larger than the blower unit and lies sealingly against the housing wall. The retaining springs are pretensioned when they are pushed in and thus fix the blower unit and the cover frame in the installed position.

Dazu ist insbesondere vorgesehen, dass die Rastfeder eine eine Halterung des Gehäuses in der Raststellung hintergreifende Rast umfasst, die in einen Einschubbügel übergeht, der derart ausgebildet ist, dass der Einschubbügel beim Einsetzen der Baueinheit in das Gehäuse die Halterung entlanggleitet. Der Bügel wird dabei beim Einschieben der Baueinheit in das Gehäuse mit fortschreitender Einschubtiefe immer weiter vorgespannt, bis er infolge dieser Federvorspannung selbstätig die Rast hintergreifen kann, wenn die erforderliche Einschubtiefe erreicht ist. Damit ist die Gebläseanordnung sicher im Gehäuse gehalten.For this purpose, it is provided in particular that the detent spring comprises a detent engaging behind the holder of the housing in the detent position, which merges into an insertion bracket which is designed such that the insertion bracket slides along the holder when the structural unit is inserted into the housing. When inserting the assembly into the housing, the bracket is increasingly biased as the insertion depth progresses until it can automatically engage behind the catch as a result of this spring preload when the required insertion depth is reached. The fan arrangement is thus held securely in the housing.

Zur Verlagerung der Rastfeder entlang der Führung ist vorzugsweise ein gelenkig an der Rastfeder angreifender Hebel vorgesehen, der in der Raststellung in die Führung eingeschwenkt ist und die Rastfeder gegen ein Verschieben entlang der Führung sichert und der in der Freigabestellung, zur Entnahme der Gebläseanordnung aus dem Gehäuse, aus der Führung ausgeschwenkt ist und den Verschiebeweg der Rastfeder entlang der Führung freigibt. In dieser Freigabestellung kann die Rastfeder mit dem Hebel nach innen, also in Richtung Gehäusezentrum verschoben werden, um die Rast zu lösen und um die Gebläseanordnung mit wenigen Handgriffen aus dem Gehäuse entnehmen zu können.To displace the detent spring along the guide, an articulated lever on the detent spring is preferably provided which is pivoted into the guide in the detent position and secures the detent spring against displacement along the guide and which in the release position for removing the fan arrangement from the housing , is pivoted out of the guide and releases the displacement path of the detent spring along the guide. In this release position, the detent spring can be moved inwards with the lever, that is, in the direction of the housing center, in order to release the detent and to be able to remove the blower arrangement from the housing in a few steps.

Des Weiteren empfiehlt es sich, wenn die Baueinheit frontseitig ein Filterelement in einer Aufnahme aufnimmt, dass von einem lösbar an die Baueinheit angesetzten Deckel überdeckt ist. Dieser Filter kann gegebenenfalls durch einen Klettverschluss in seiner Lage fixiert sein. Besagter Deckel kann schnappverschlussartig an der Gebläseanordnung angreifen.Furthermore, it is advisable if the assembly receives a filter element in a receptacle on the front, which is covered by a cover which is detachably attached to the assembly. This filter can optionally be fixed in position by means of a Velcro fastener. Said cover can engage the blower arrangement like a snap lock.

Die Rastfedern garantieren die ordnungsgemäße Fixierung der Gebläseanordnung im Gehäuse. Zwischen Gebläse und Gehäusedeckel sind vorzugsweise Dämpfungsringe angeordnet, welche eine Körperschallübertragung vom Motor mit Laufrad auf das Gehäuse dämpfen. Insbesondere ist dabei zwischen der Gebläseanordnung und dem Gehäusedeckel eine Dämpfungseinlage vorgesehen. Zusätzlich empfiehlt es sich, wenn die Motorelektronik dem Gehäusedeckel zugeordnet ist. Zudem erlauben die Haltefedern zwischen Gebläse und dem Abdeckrahmen ein besagtes Ausrichten und den Ausgleich von Winkelfedern bei Einbau. Durch Zugfedern zwischen Gebläse und Abdeckrahmen können Einbautiefen bis zu 80 mm überbrückt werden. Das Gehäuse kann in verschiedenen Lagen, insbesondere um jeweils 90° gedreht, in ein Mauerwerk eingemauert werden. Das Gebläse wird in einer vorgegebenen Lage bezüglich des Gehäuses in das Gehäuse eingesetzt. Eine Abdeckplatte kann dann in jeder beliebigen Lage auf einen Abdeckrahmen, welcher mit dem Gehäusedeckel verbunden, aufgesetzt werden.The catch springs guarantee the proper fixation of the fan arrangement in the housing. Damping rings are preferably arranged between the blower and the housing cover, which dampen structure-borne noise from the motor with the impeller to the housing. In particular, a damping insert is provided between the blower arrangement and the housing cover. It also recommends when the engine electronics are assigned to the housing cover. In addition, the retaining springs between the blower and the cover frame allow said alignment and compensation of angle springs during installation. Tension springs between the blower and cover frame allow installation depths of up to 80 mm to be bridged. The housing can be walled into masonry in various positions, in particular rotated by 90 °. The fan is inserted into the housing in a predetermined position with respect to the housing. A cover plate can then be placed in any position on a cover frame, which is connected to the housing cover.

Ist die Motorelektronik unterhalb des Filters angeordnet und entsprechend befestigt, so kann diese gesamte Einheit gegebenenfalls problemlos innerhalb kürzester Zeit getauscht und ersetzt werden, ohne die gesamte Vorrichtung demontieren zu müssen. Der Netzanschluss der Gebläseeinheit an einen Stromanschluss wird vorzugsweise über eine im Gehäuse vorgesehene Netzklemme hergestellt. Eine weitere Verdrahtung der Gebläseeinheit ist dann nicht mehr nötig, da die Stifte der Motorelektronik beim Einschieben in das Gehäuse in Buchsen an der Netzklemme automatisch eingreifen und eine elektrische Verbindung herstellen.If the motor electronics are arranged underneath the filter and fastened accordingly, this entire unit can, if necessary, be exchanged and replaced without problems in the shortest possible time without having to disassemble the entire device. The power connection of the blower unit to a power connection is preferably established via a power terminal provided in the housing. Further wiring of the blower unit is then no longer necessary since the pins of the motor electronics automatically engage in sockets on the power terminal when inserted into the housing and establish an electrical connection.
