Definitions

  • the invention relates to a device 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 via a connecting piece to a supply air duct, the connecting piece being assigned a perforated disk.
  • 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 be arranged in a ring, for example made by punching. 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. This significantly improves the air flow into a room.
  • a ceiling swirl outlet according to the preamble of claim 1 is known from DE-U-87 01 001.
  • a nozzle There is a nozzle, a perforated disc with channel wall and flange and a corresponding swirl disc and an outlet funnel held together by an annular bracket.
  • the assembly of such a multitude of elements is not easy and furthermore, individual elements such as, for example, perforated disk and swirl disk cannot be separated from one another without the entire ceiling swirl outlet being disassembled. Furthermore, the distance between the perforated disk and the swirl disk cannot be changed, so that the volume of the space between the perforated disk and the swirl disk cannot be changed.
  • 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. Furthermore, the assembly of the ceiling swirl outlet and also its disassembly should be facilitated, for example for the purpose of cleaning.
  • an inwardly directed annular collar with an inlet opening for the supply air is formed on the connecting piece and that the perforated disk strikes the annular collar from the inside of the base body or from the outside and covers the inlet opening and is connected to the swirl disk by a screw is.
  • the device according to the invention enables an exact pressure increase of the air, so that the distribution within the device is evened out. It has been shown that the assignment of the perforated disk to the swirl disk within the connecting piece ensures draft-free and problem-free air supply.
  • a good holding of the perforated disk ensures the arrangement of the inwardly directed ring collar on the connecting piece, on which the perforated disk can 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 the screw, whose threaded shaft extends through the perforated disk, is penetrated approximately in the middle of the swirl disk.
  • the separate fixing of the perforated disk on the ring collar could also be omitted by the perforated disk on the outside of the ring collar strikes and the screw thus acts as a tension screw between the perforated disk and 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.
  • the device according to the invention can be manufactured in a wide variety of diameters depending on the desired or the required amount of air. They are simple to manufacture and offer 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 followed 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.
