Definitions

  • the invention relates to an air outlet according to the preamble of claim 1
  • Air outlets and in particular ceiling air outlets are known in various embodiments.
  • swirl outlets with fixed guide vanes are known (cf. EP-A-0 129 000).
  • the jet direction of the emerging air jets is predetermined and cannot be changed by the angle of attack of the fixed guide vanes. This applies in particular to the vertical component and consequently the direct passage of air through the air passage gaps between the guide vanes.
  • throttling of the vertical component which is used to heat the room air, is often required. - This is where the invention begins.
  • the US-A-26 72 087 describes an air outlet with the features of the preamble of claim 1.
  • the lower plate 28 is not designed as a swirl plate, but only has radial, upright blades; which divide the plate into a plurality of chambers over its circumference. Each of these chambers has an air passage gap 26.
  • Two impellers 40, 50 with air passage openings 54, 56 are arranged above the plate 28.
  • the two wing plates are rotatably mounted, namely they can be rotated with respect to the plate 28 with congruent air passage openings 54, 56 in order to achieve an axial air passage with respect to the air passage openings 26 in the plate 28 (see FIG. 6), or in order to achieve an oblique exit of the air (see FIG.
  • the invention has for its object to provide an air outlet, in particular ceiling air outlet, of the type described in the introduction, in which the jet direction and in particular the direct passage of air can be adjusted in a relatively simple and functional manner or can be adjusted to suit the respective thermal load case and the blow-out height .
  • the invention recommends that the impeller is rotatably and adjustably mounted in the air supply nozzle, for. B. is adjustable by means of an electric servomotor. In this way, the beam direction or coverage of the air passage gaps can be changed even after the air outlet or ceiling air outlet has been installed.
  • the invention provides that the impeller is adjustable as a function of the air temperature by means of a stationary expansion element and an engaging spring element. That depends on the air temperature Working expansion element thus ensures the adjustment of the impeller in the sense of a greater or lesser coverage of the air passage gaps between the guide blades.
  • the invention teaches that the impeller between an uninterrupted or interrupted circumferential clamping bead in the air supply nozzle and the central surface the swirl plate with a predetermined coverage of the air passage gaps between the guide vanes is clamped in the air supply connection in a rotationally fixed manner.
  • the central surface can have an elastic coating with a high coefficient of friction, which is therefore relatively blunt. - Otherwise, the impeller can be punched out of a sheet metal plate and its hub can be deep-drawn in the course of simple production.
  • a ceiling air outlet is shown with an air supply nozzle 1 and at the outlet end of the nozzle radially and with a predetermined angle of attack arranged guide vanes 2 for generating swirl, air passage gaps 3 being provided between the guide vanes 2 in an axial or vertical projection.
  • An impeller 4 with a number of radial impingement vanes 5 corresponding to the number of guide vanes 2 is arranged upstream of the guide vanes 2.
  • the baffles 5 are located in the horizontal plane and are wider than the air passage gaps 3 between the guide vanes 2. As a result, the air passage gaps 3 can be covered completely or partially in axial projection by means of the baffle vanes 5.
  • the impeller 4 can be rotatably and adjustably mounted in the air supply nozzle 1.
  • a swirl plate 6 with an air outlet opening 7 concentric with the air supply duct 1 and in the air outlet opening 7 with a central surface 8 radially arranged guide vanes 2 is fastened to the outlet end of the nozzle.
  • the central surface 8 is designed as a support for a hub 9 on the impeller 4.
  • the impeller 4 is between a continuously rotating Clamping bead 10 in the air supply pipe 1 and the central surface 8 of the swirl plate 6 with a predetermined coverage of the air passage gaps 3 between the guide blades 2 in the air supply pipe 1 clamped against rotation.
  • This torsional strength is achieved by the clamping action and by the fact that the central surface 8 has an elastic coating 11 with a high coefficient of friction, that is to say is relatively blunt.
  • the impeller 4 is punched out of a sheet metal plate and its hub 9 is deep-drawn to form a cup.
  • it can also be an injection-molded plastic part.
  • the air outlet can have not only a round, but also a square cross section.
