Definitions

  • the invention relates to an air outlet, in particular ceiling air outlet, with an air supply nozzle and at the outlet end of the nozzle radially and with a predetermined angle of attack arranged guide vanes for swirl generation and with axial projection air passage gaps between the guide vanes.
  • Air outlets and in particular ceiling air outlets are known in various embodiments.
  • swirl outlets with fixed guide vanes are known.
  • 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 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 impeller arranged upstream of the guide vanes, the impingement vanes of which extend in the radial plane and optionally partially or completely cover the air passage gaps between the guide vanes.
  • this overlap can already be set during the installation of the air outlet or ceiling air outlet by appropriate mounting of the impeller.
  • the jet direction in the outlet is adjustable.
  • 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 vanes.
  • the invention teaches with independent importance that the central surface is designed as a support for a hub on the impeller. This results in a particularly simple mounting for the impeller.
  • 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 swirl generation, 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 blades 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 not only have a round, but also an angular cross section.
