  • a fan housing is known from US-A-3 877 357.
  • an inner, frame-like covering part serves, on the one hand, to shield the edge area of the passage opening of a plate, a panel or the like against weather influences and, on the other hand, is used to hold or store a flap , by means of which the passage opening can optionally be closed or released.
  • the outer cover of this fan housing has the task of covering the actual passage opening and thereby causing a multiple, for example, S or Z-shaped deflection of the continuous air flow.
  • the two components forming the fan housing can be formed from flat plate material, in particular thermoformed from plastic plates, before they are subsequently assigned to the passage opening in the plate, the panel or the like from opposite sides for the purpose of optimal shielding will.

  • the invention is also characterized in that the inner, frame-like covering part is provided with a hood-like shape protruding outwards through the passage opening of the wall, roof, ceiling, plate, panel or the like the boundary walls of this hood-like formation occupy and / or maintain a minimum distance everywhere from the inner surfaces of the outer cover hood, and that the opening edge of the hood-like formation of the inner trim part is located at a distance from the boundary edge for the air passage of the cover hood.

  • That the mode of operation of ventilation devices designed for blower operation can be influenced by a suitable design of the air duct in a manner which produces a so-called siphon effect and thereby conveys more air than would be the case with the blower alone in free-blowing operation already taught for example with DE-C-15 03 511 (see column 5, lines 7 to 11).

  • This can be achieved, if necessary, that the motor-driven blower (s) are accommodated with a part of their axial height below or outside the actual fan housing in the cup-shaped or trough-shaped profiled support panel, while the remaining part of the axial height through the passage opening in the fan housing engages (see, for example, US-A-2 665 625).

  • insect or bird protection grids can also be fixed at the same point, if necessary.
  • the passage opening 5 in the flat component 2 can also be assigned a shielding molded part 86 on the inside, which extends over the entire length of the passage opening 5.
  • One longitudinal half of which can be formed by a closed cup 87 and the other longitudinal half of which can also be formed by a perforated or mesh grid 88 which is also cup-shaped.
  • the rotating body 70 is used as the closure member, which extends and extends in the longitudinal direction of the fan housing 1 has bearing axis passing through the journal 78.
  • This rotary body 70 delimits in the rotary end position according to FIG. 10 between its walls 71 and 72 an air duct 89, in which at least one axial fan 22 with its housing or casing ring 74 sits as a motor-driven fan, the plane of rotation of which is approximately transverse to the direction of passage of the Air duct extends.
  • the possibility is also open to support the inner trim part 3 either with its contact flange 82 inside the outer cover 10 next to the edge of the passage opening 5 against the outside of the plate or the panel , or, to let it protrude with its hood-like shape 6, the passage opening 5 of the plate or panel 2 from the inside to the outside, so that its abutment or support flange 4 rests on the inside 7a of the plate or panel 2.
  • the motor-driven blowers which are housed exclusively in the hood-like shape 6 of the inner trim part 3 and are carried solely by the blower, are accessible from the interior of the room through the passage opening 5, in particular for maintenance and repair purposes.
  • FIG. 13 also shows details of a type of ventilation device modified compared to FIG. 1.
  • the cover 10 and the inner trim part 3 are each attached to the outside 7b of the flat component 2 only via relatively short contact or support flanges 11 and 4.
  • the one used to fix the motor-driven blowers, e.g. Axial fans 22, in their functional position by the elastic molded part 26 (FIG. 1) do not apply preload pressure to the flat component 2, e.g. the plate, the panel or the like can react. Rather, this prestressing pressure is completely absorbed in the hood-like formation 6 of the inner, frame-like covering part 3.
  • the profile rail 20 which forms the carrier for the motor-driven blowers, namely axial fans 22, can be detachably anchored to special brackets 90, for example by means of screws 90, which extend below the opening 15 from the inside of the wall, the inner trim part 3 into the fan interior 25 protrude into it.
  • the brackets 90 can be designed in the manner of a vibrating metal, at least in the effective area of the screws 91, e.g. equip with elastomer sleeves to further improve the vibration-damping effect.
  • brackets 90 and the profile rail 20 with hook legs which, together with the restoring effect of the elastic molded part 26, produce an automatic clamping effect and thereby the positioning of the blowers 22 in the hood-like shape 6 of the frame-like trim part 3 without Allow by means of screws 91 or the like.
  • Either an angle rail can be used as the console 90, which extends continuously over the entire installation length of the motor-driven blowers, in particular axial fans 22, or else short angle pieces can be used which extend over the installation length for the motor-driven blowers, in particular axial fans 22 sit distributed on the inside of the inner, frame-side trim part 3.
