Definitions

  • the invention relates to a swirl outlet with an outlet disk, in which star-shaped outlet slots are formed, each of which is assigned an air guide lamella.
  • Such swirl outlets are known in many forms and designs. Reference is made here, for example, to DE-OS 40 26 932.9. Bearing disks, such as are shown, for example, in DE-OS 38 32 052.5, are generally used to fix the air guide vanes.
  • the present invention has for its object to further improve these swirl outlets and to increase the amount of air to be introduced.
  • openings are provided in the outlet disk between the outlet slots and / or around the outlet slots.
  • the fluidic connection between the air guide fins and the openings is also important.
  • the air flows through the openings more or less deeply vertically into a room.
  • the air guide fins give the air flow, which emerges from the outlet slots, a swirl, which engages in the vertical air flow of the openings and deflects them. This significantly improves the induction into the room.
  • the openings are not only arranged between the outlet slots, but there is a ring of openings around the outlet slots. If the outlet disc is round, this ring is also round. However, an angular configuration is also conceivable, depending on how the outlet disk is shaped. It is essential that the outer ring of openings creates a kind of cylindrical air curtain in which the swirled air can be introduced deep into a room. In this way, warm air in particular can be introduced very deeply into a room before the targeted guidance is canceled and then the warm air is distributed and rises again.
  • the majority of the openings between the outlet slots are formed with a relatively small diameter, while the openings in the ring around the outlet slots have a larger diameter.
  • the air flows through the outlet slots more freely, so that the sufficient swirl can be given to it.
  • the openings in the ring around the outlet slots also allow the air to enter the room more freely.
  • the air emerging from the openings with a smaller diameter is carried away by the swirl flow, but pulls the swirl flow down into the room. From this it can be seen that the individual different air flows complement each other effectively.
  • a swirl outlet R according to the invention has gem.
  • outlet slots 5 are formed in the outlet disk 1.
  • these outlet slots 5 have different lengths l1 and l2.
  • the openings 6 do not all have the same diameter, but can be shaped differently. All of these shapes and differences in shape are intended to be encompassed by the present inventive concept.
  • 5 slats 7 are assigned to the outlet slots. These slats 7 are preferably rotatably mounted on an axis 8, wherein the axis 8 extends between two bearing disks 9 and 10.
  • the bearing disks 9 and 10 can be punched out of the material of the outlet disk 1 during the punching process for the outlet slots 5 and bent upwards. Other definitions for the bearing disc are also within the scope of the invention. However, the bearing disks preferably have a foot web 11, which forms a groove 12 or 13 on both sides toward the bearing disk 9 or 10. To fix the bearing disk 9 or 10 in the outlet slot 5, the bearing disk 9 or 10 can then be inserted into the outlet slot 5 and rotated until the marginal edges of the outlet slot 5 each enter the groove 12 or 13. As a result, the setting of the fins 7 is simplified, and no additional welding spots or the like are. Fixings needed.
