Definitions

  • the invention relates to a swirl outlet for insertion into a ceiling and for supplying air to a room, the air emerging from recesses in a cover plate.
  • Twist outlets are known in many forms and designs.
  • slots are formed in a cover plate in a star shape, to which employed air-guiding blades are assigned. These air guide fins cause the air to exit from these star-shaped outlet slots with a swirl.
  • the object of the present invention is to provide a relatively small swirl outlet in which the air outlet quantity can be varied and in which the air can escape both horizontally and vertically.
  • the cover plate forms an annular air outlet gap with a frame.
  • the recesses provided in the cover plate can have any number and configuration. They depend on the given room conditions and supply air temperatures.
  • the size of the air outlet gap should preferably be changeable. This is done for the sake of simplicity in that the cover plate is inserted into the frame by means of a threaded rod, so that the cover plate can be screwed more or less deep into the frame.
  • a support star in the frame offers itself as a holder for the cover plate, which preferably has an internal thread in the axial direction of the swirl outlet, in which the above-mentioned threaded rod engages.
  • the cover plate is held on the threaded rod between an Allen head, which is molded onto the threaded rod, and a lock nut.
  • the Allen head is preferably inserted into a sleeve which is molded onto the cover plate from the inside.
  • the window frame itself preferably has a funnel-shaped connecting piece, which is adjoined by an edge wall.
  • This boundary wall forms together with the cover plate or with an edge strip of the cover plate, the above-mentioned air outlet opening.
  • This edge strip can be bent relative to an inner plate of the cover plate, so that the slope of the annular exit jet from the air outlet gap is determined thereby. This slope can be changed as desired.
  • the cover frame which holds the cover plate, is, to a certain extent, inserted into a holding frame, which holds the entire swirl outlet on the ceiling.
  • This holding frame has indentations on which strips are supported, which in turn are fixed to the support star. If these indentations are designed to rise obliquely, then by rotating the window frame, it can be drawn more or less into the holding frame together with the cover plate. As a result, a distance which an edge at the edge wall of the frame mentioned above from the underside of the ceiling will be kept more or less large. The edge then forms a further air outlet opening to the underside of the ceiling, so that here a corresponding amount of supply air can escape into the room directly along the ceiling.
  • swirl blades should be fitted on the cover plate from the inside. These swirl blades preferably run like blades around the above-mentioned longitudinal axis or around the threaded rod and, if desired, can be inclined. For example, the recesses can then also run along the swirl blades. However, many possibilities are conceivable here.
  • a swirl outlet R acc. Fig. 1 has a cover plate 1 in the use position, which is penetrated by recesses 2.
  • the recesses 2 are arranged in the manner of a paddle wheel and are arranged around an axis A of the cover plate 1.
  • the cover plate 1 also has an inner plate 3 and a bent edge strip 4 which runs around the inner plate 3.
  • the edge strip 4 forms, together with a frame 5, an annular air outlet gap 6. A relatively large amount of supply air can be introduced obliquely into a room through this air outlet gap 6.
  • the frame 5 has a diffuser-like cross section, ie it essentially consists of a funnel-shaped nozzle 7, to which a curved edge wall 8 is connected.
  • a diffuser-like cross section ie it essentially consists of a funnel-shaped nozzle 7, to which a curved edge wall 8 is connected.
  • FIG. 2 strikes an edge 9 of this edge wall 8 from below onto a ceiling 10, but it can also maintain a certain distance from this ceiling 10 and thereby form a horizontal outlet opening. This happens because that the frame 5 is rotatably inserted about the axis A in a holding frame 11 which is fixed to the ceiling 10 or to an air duct system, not shown.
  • a support star 12 In order to hold the frame 5 in the holding frame 11, a support star 12 has strips 13 placed thereon which, when inserted into the holding frame 11, rest on a recess 14 in the holding frame 11.
  • This indentation 14 is, as indicated in FIG. 2, formed obliquely ascending.
  • the frame 5 is more or less drawn into the holding frame 11 when rotating about the axis A, so that the edge 9 can maintain a more or less small distance from the ceiling 10.
  • an internal thread 15 is formed in the support star 12 and is penetrated by a threaded rod 16.
  • the threaded rod 16 holds the cover plate 1 between an Allen head 17 and a lock nut 18, here a cover 19 being integrally formed on the cover plate 1, into which the Allen head 17 is countersunk.
  • swirl blades 20 are connected to the sleeve 19 and are placed on the inner plate 3 from the inside like a paddle wheel. In the exemplary embodiment shown, they partially run along the recesses 2. If desired, the swirl blades 20 can also be inclined.
