Definitions

  • the invention relates to a swirl diffuser with guide vanes arranged concentrically around the central axis of a connecting piece that widens in the direction of flow in the direction of flow.
  • Such well-known swirl outlets are arranged, for example, in the ceiling area of a room to be ventilated and / or air-conditioned and are connected to an air duct system. Due to the shape of these passages, the emerging air jets receive a high swirl impulse and are thus able to mix intensively with room air before they reach the lounge area of the room, so that drafts are avoided there.
  • the swirl diffusers which are tried and tested per se, are generally made of plastic, preferably by injection molding, and are therefore relatively inexpensive. Swirl diffusers made of plastic, however, have two major disadvantages: On the one hand, the swirl diffusers made of plastic lack sufficient temperature resistance, and the diffusers can even catch fire, depending on the plastic used to manufacture them. On the other hand, swirl diffusers made of plastic are difficult to paint and can therefore only be adapted to the individual color spectrum of a room with great effort.
  • EP-A-0 129 000 also discloses nozzle-free swirl outlets which are produced from a sheet metal plate and have guide blades punched out therefrom in the form of tongues.
  • the invention has for its object to propose a swirl diffuser of the type described above, which can be produced at least as rationally as the known swirl diffusers and also has the advantages that it is characterized both by a high fire resistance and also efficient and durable with one individual paint can be provided.
  • the components of the swirl outlet should be able to be connected to one another sufficiently firmly in a simple manner.
  • each guide vane has at least one projection or a recess on its radial outer edge, with which the guide vane is latched into a recess or a projection on the inside of the connecting piece.
  • the projections can be needle-shaped and engage in appropriately designed recesses.
  • recesses provided in the sheet metal socket as openings and initially allowing the projections on the outer edges of the guide vanes to protrude slightly beyond the outer circumference of the sheet metal socket, in order to finally compress or crank them in the manner of a riveted connection.
  • connection types described above makes it possible to arrange the two components relative to one another such that, according to a further embodiment of the invention, the sheet metal plate from which the blades are formed, with the side over which the blades protrude, lies firmly against an end face of the sheet metal socket.
  • a compact design of the swirl diffuser results from the fact that the outer contour of the sheet metal plate matches the outer contour of the sheet metal socket defined by a collar.
  • Swirl diffusers designed in this way represent an essentially cuboid or disk-shaped structure which, for example, can be easily integrated flush with the ceiling in cassette-shaped recesses.
  • the sheet metal socket and the sheet metal plate can be circular or polygonal, without influencing the simple method of manufacturing the passage.
  • At least two sheet metal plates provided with punched-out guide vanes are arranged one above the other and rotated relative to one another in such a way that the guide vanes of one sheet metal plate penetrate the guide vane punch-outs in the other sheet metal plate and the guide vanes fully cover the guide vane recesses in the projection.
  • sheets provided with uniformly designed and arranged guide vanes can be nested one inside the other, all that is required is to twist the sheet metal plates around their center line perpendicular to the plate plane over an angle that is smaller than the angle between two adjacent guide vanes, in order to ensure all openings through the projection of the guide vanes to cover completely.
  • the swirl passage consists of a sheet metal plate 1 with tongue-shaped guide vanes 2, which are arranged concentrically around a central axis perpendicular to the plane of the sheet plate 1 at such a distance that a central area 3 and an edge area 4 of the sheet metal plate 1 are retained unchanged by the punching process .
  • the swirl passage consists of a connection piece 5, the cylindrical part 6 of which, with a radius R, merges into an arc in a collar 7 projecting radially outwards.
  • the minimum inner diameter of the nozzle 5 is dimensioned such that sections of the radial outer edges of the guide vanes 2 are pressed against the inner wall of the nozzle 5, while the side of the sheet metal plate 1 facing the nozzle 5 lies firmly against the end face of the nozzle 5.
  • the connecting piece 5 can either be formed from a sheet metal plate or can also consist of a sheet metal tube, the collar 7 being molded on in the rolling process.
  • the two components of the swirl diffuser according to the invention can thus be produced in a rational manner in a stamping and bending process and, for example, can also be rationally provided with the individually desired color, for example in the immersion process.
  • the square layout of the swirl diffuser allows it to be integrated, for example, flush with the ceiling in cassette-shaped recesses in an architecturally advantageous manner.
