Definitions

  • the invention relates to a ventilation device for rooms with a radial fan arranged in a cuboid housing and a casing spiral comprising the impeller within the housing as an insert body, in which the casing spiral and a tangential and / or radial air duct connected to it directly in the block-like insert body is formed from sound-absorbing material, for example foam or foam rubber.
  • a ventilation device for rooms in which an insert body made of sound-absorbing material is arranged in a cuboid housing, which includes a casing spiral, which encompasses the impeller of the radial fan and to which is directly and approximately tangentially and / or an air duct connects radially.
  • a box-like housing part is additionally placed on the end face of the insert body made of sound-absorbing material and enclosing the casing spiral, which is covered on its inner wall surfaces with sound-absorbing laminated bodies.
  • a similar ventilation device is part of the prior art through US-A-2 061 535.
  • the air inlet and the air outlet in the height direction of the housing are arranged at a distance above one another and on housing walls that face away from one another, so that a correspondingly large overall height also results here.
  • the air duct from the fan to the air outlet is meandering in order to obtain the longest possible air flow path.
  • the housing of the ventilation device must also have a relatively large overall length.
  • the insert body made of sound-absorbing material is formed by a multiplicity of plate-shaped bodies lying one above the other, so that this results in a relatively complicated structure of the entire ventilation device.
  • the aim of the invention is to bring about a favorable flow distribution of the air already within the cuboid housing, so that the air flowing into the room to be ventilated cannot cause any noticeable drafts.
  • long flow paths should be avoided within the cuboid housing, so that the cuboid housing can be used with small structural dimensions and therefore requires only a small installation space when it is arranged on the inside of building walls.
  • the insert body is at a distance from the adjacent building wall in the region of an open section of the air duct, such that the open section opens into an air distribution chamber located in front of the end face of the insert body in the housing , and that the outer longitudinal sides of the insert spiral containing the casing spiral and the air duct are provided, at least over the length section containing the open section of the air duct, with bevels which run at an acute angle to the adjacent longitudinal housing walls, in which air passages, e.g. B. in the form of a grid perforation.
  • each swivel flap is provided as a closure and air guide member. Furthermore, it has proven to be important if, according to claim 3, each swivel flap is mounted on the housing longitudinal walls near the housing rear wall and consists of a profile having two obtuse angles to one another, the angular distance of the legs from one another to the angle is matched between the end face and the inclined longitudinal side of the insert body containing the casing spiral and the air duct.
  • each swivel flap is adjustable between its closed position and its open position by means of a rotary knob or toggle mounted on the end wall of the housing via a crank pin which engages in a cam slot provided on the free leg of the swivel flap.
  • a simple structure of the ventilation device can also be achieved according to the invention in that, according to claim 5, the longitudinal side walls and the end wall of the cuboid housing are each formed by extruded profiles made of light metal or plastic, while its transverse walls are manufactured as molded parts from light metal die casting or plastic injection molding are and the rear wall is a folded molding made of sheet metal.
  • the two longitudinal side walls of the cuboid housing consist of the same, but mirror-inverted extruded profiles, and the end wall of the same is formed by two mirror-inverted extruded profiles and an additional extruded profile that couples them together.
  • the one with the outside air passage of the housing opposite wall of the casing spiral is according to the further inventive feature of claim 7 of a plate-like flat insert body made of sound-absorbing material, for. B. foam plastic or foam rubber, on the inside of which a support plate of soundproof material rests, to which the stator of the radial fan is attached.
  • a plate-like flat insert body made of sound-absorbing material, for. B. foam plastic or foam rubber, on the inside of which a support plate of soundproof material rests, to which the stator of the radial fan is attached.
  • a particularly favorable embodiment of the ventilation device can be achieved according to claim 8 in that the plate-like flat insert body only covers the part of the air duct that connects tangentially to the casing spiral, while the radial part of the same over its entire length is spaced from the opposite housing wall and / or has a soundproofing pad attached to it.
  • a sideways flow distribution of the air can be advantageously achieved within the cuboid housing, which results in a further improvement in the damping effect.
  • an interchangeable filter insert for example made of a multiply folded filter paper laminated body, to the block-like insert body, at least in the radial part of the air duct, the filter insert being at least over a partial height in the block-like insert body extends into it, while its remaining part height projects into the free space between the insert body and the housing end wall.

  • the outer surface of the housing rear wall 2 is covered with a vibration-damping coating 18, for example a thin layer of elastic foam plastic or foam rubber. This covering is provided in the aligned position with the air passage opening 2 "'of the housing rear wall 2 with a corresponding cutout 18'.
