Definitions

  • the invention relates to a device, in particular for discharging supply air into a room, with a base body on which on the one hand a swirl disk is fixed and on the other hand connects to a supply air duct or the like via a connecting piece.
  • Such a device is known for example as a ceiling swirl outlet.
  • supply air which is brought in via appropriate duct systems, meets a swirl disk from the inside, which is interspersed with swirl outlets.
  • These swirl outlets can, for example, be arranged in a ring and can be produced by stamping. Wall parts between two punchings are inclined in relation to the plane of the swirl disk, so that the escaping air also receives a corresponding swirl.
  • the inventor has set itself the goal of improving a device of the type mentioned above, in which the supply air is discharged more quietly into the room and in which the distribution of the supply air is also improved.
  • a perforated disk is assigned to the nozzle.
  • This perforated disk is preferably penetrated by fine-jet holes, which, according to the results of laboratory tests carried out, enables a much more precise pressure increase, so that the distribution in the stages within the device is evened out. It has been shown that the assignment of the fine jet perforated disk to the swirl disk within the connecting piece ensures draft-free and problem-free supply of air in ventilation technology.
  • the perforated disk should preferably cover the clear width of the connecting piece. It is within the scope of the invention that the perforated disc can be placed on the nozzle as well as inserted in the nozzle. However, a better mounting of the perforated disk ensures the arrangement of an inwardly directed annular collar on the connecting piece, on which the perforated disk can then strike from the inside of the base body or from the outside.
  • the perforated disk is attached to this ring collar, for example, by spot welding, rivets or the like.
  • the arrangement of the perforated disk also enables the swirl disk to be held more easily. For this it is sufficient if a screw passes through the center of the swirl disk, the threaded shaft of which passes through the perforated disk.
  • the separate fixing of the perforated disk on the ring collar could also be omitted, for example, in that the perforated disk strikes the annular collar from the outside and the screw thus acts as a tension screw between the perforated disk and the swirl disk.
  • An edge wall in the transition area between the ring collar and connecting piece is then sufficient, for example, to center the perforated disk. To do this, the ring collar only needs to be pulled a small amount into the socket.
  • This step outlet according to the invention can be manufactured in a wide variety of diameters, depending on the request or the required air volume. Its manufacture is simple, but it offers enormous functional advantages over the known ceiling swirl diffusers.
  • a step outlet R has a step-shaped base body 1.
  • This base body 1 has a connecting piece 2, which is adjoined at the end by an inwardly directed annular collar 3.
  • This ring collar 3 includes an inlet opening 4 for a supply air to be introduced, for example, into a room.
  • the inlet opening 4 is covered by a perforated disc 5 which has a large number of fine-jet holes.
  • the neck 2 has a step-shaped shoulder shoulder 7 which opens into an abutment ring 8.
  • a swirl disk 9 strikes this bearing ring 8.
  • the swirl disk 9 engages around the abutment ring 8 with a side wall 10.
  • the swirl disk 9 has annularly arranged outlet slots 11, as can be seen better in particular in FIG. 1. These outlet slots 11 are produced by stamping, wall parts 12 between two outlet slots being at least partially screwed in or inclined toward the interior I of the base body 1.
  • the swirl disk 9 is fixed to the base body 1 by means of a screw 13 which strikes the swirl disk 9 from the outside with a screw head 14 and with a Threaded shaft 15 partially penetrates the perforated disc 5.
