  • the fan housing preferably has on its outer surface outwardly open longitudinal channels in which support elements are arranged. These support elements rest on the inner walls of the outer housing and / or on the inspection flap or on the insulation material there. It should be particularly emphasized that, by appropriate dimensioning, the fan housing designed in this way can be arranged, so to speak, in a press fit in the interior of the outer housing, without the need for further fastening elements. Reliable support of the fan housing is ensured by means of the support elements, and manufacturing tolerances can also be compensated for without further notice. It is readily apparent that when the inspection flap is closed, a corresponding contact pressure can also be applied in order to ensure that the fan housing is securely fixed.
  • the support elements mentioned preferably consist of a resilient, elastic material and they extend over the entire length of the fan housing. Such support elements are inexpensively cut from endless profile material to the desired length and they allow tolerance compensation without difficulty within wide limits.
  • Four such longitudinal channels are advantageously provided, which are assigned to the corners of the outer housing. The support elements arranged in the longitudinal channels thus engage in the corners of the outer housing, so that a rotation lock for the fan housing is created in a particularly simple manner.
  • Two longitudinal ducts are expediently arranged on the two end regions of the fan housing, these end regions forming the outer flow duct of the fan housing.

  • the flexibility of the insulation material and / or the support elements is particularly important here.
  • a support wall is provided at least at the ends in the interior, which is preferably fastened in longitudinal channels of the outer housing by means of fastening elements. Because of such supporting walls, the stability of the ventilation device is not negligibly improved.
  • the outer housing can thus be of a comparatively thin-walled design, which results in considerable material and weight savings. At this point, it should be particularly emphasized that the outer housing, like the cover flap and the inspection flap, is made from extruded material, with optimal use of material being ensured due to the retaining walls according to the invention.
  • the longitudinal channels mentioned have undercut areas in which the fastening elements mentioned engage, the latter preferably being designed as screws or as T-shaped projections of the supporting wall. This ensures a particularly simple and reliable fixing and fastening of the retaining walls.
  • the supporting wall preferably has at least one bore or recess arranged perpendicular to the rear wall of the outer housing, into which fastening means, in particular a screw, can be inserted.

It should be emphasized at this point that the articulation of the cover flap act in the same way as a labyrinth seal on the inspection flap, that is to say the front longitudinal edge and the associated claw of the cover flap explained above. It can be seen that an undesirable air flow is thus reliably prevented when the cover flap is closed.
  • a longitudinal channel is preferably provided in the region of the front edge of the outer housing, in which the electrical lines for the fan motor and / or for the actuator are arranged.
  • This longitudinal channel can easily be covered with a corresponding profile, so that the electrical lines are largely protected from external influences.

  • This embodiment is particularly suitable in the event that the front surface of the ventilation device is substantially flush with other components, such as window frames, walls or the like. Since the inspection flap only needs to be pivoted through a small angle when opened, there must be practically no free space below the lower wall of the housing, in which the lower edge of the inspection flap would otherwise have to pivot.
  • the longitudinal groove and / or the front edge of the housing and / or an extension of the inspection flap are arranged at an angle a with respect to the rear wall which is ⁇ 90 °, preferably ⁇ 45 ° and advantageously ⁇ 20 °.
  • the inspection flap therefore only has to be pivoted through a small angle and can then be lifted up out of the housing in this pivoted position which has now been assumed. Arrangements with small angles on the order of about 20 ° and possibly even smaller are of particular importance here, since only very small pivoting movements are thus to be carried out and the inspection flap can then be lifted up without difficulty. It is not necessary to emphasize that at such small angles the free space under the lower edge of the housing can be kept so small that it practically no longer appears. A flush arrangement of the front surface of the ventilation device or the cover flap with other components can thus be carried out without further ado.

  • the sound insulation effect can be influenced in the desired manner by suitable dimensioning of the tooth-like webs, their spacing and number. It is readily apparent that the flow paths can be increased by a corresponding extension of the overall length of the ventilation device and thus the sound insulation can also be increased. On the other hand, the air flow rate can also be influenced by the geometry of the flow paths. Even at the ends of the Suitable Danish material 46, 48 is provided for flow channels 16, 18; Corresponding insulation material is also on the rear wall and on the inspection flap.

As explained above, the inspection flap 56 can be released from the housing 2 by actuating the locking means in such a way that the inspection flap 56 can be pivoted together with the cover flap 54 around the front edge 70 of the housing 2.
  • the fans and also the other components of the ventilation device mentioned above are readily accessible. It is of crucial importance that when the inspection flap is closed or when it is locked, the fan housing 68 is simultaneously locked in the housing 2. According to the invention, therefore, no additional fastening means or the like are provided for the fan housing 68, but rather the fan housing 68 is firmly and reliably locked in the housing 2 via the support elements 104.
