Definitions
- the invention relates to a swirl outlet with an outlet disk and an edge strip encompassing this, wherein outlet slots and openings are formed in the outlet disk.
- Such swirl outlets are known in many forms and designs and in particular from German utility model 9214369.5. They have proven themselves very well for introducing warm and / or cold air, but the amount and direction of the air to be introduced into a room is limited by the number and size of the outlet slots and openings.
- the present invention has for its object to further improve these swirl outlets, to increase the amount of air to be introduced and to favor the distribution in the room.
- a funnel-shaped element is associated with the outlet disk in the edge strip which forms an annular gap with the edge strip.
- a second part of the air flows simultaneously through the defined annular gap formed between the outlet disk and the funnel-shaped element along the installation plane and thus approximately perpendicular to the other downward air flow. This increases the air flow rate again.
- the fluidic interaction between the outlet slots, which are preferably provided with air-guiding vanes, and the openings, depending on the form in front of the outlet disk, causes an air flow through the openings, which allows the air to penetrate more or less deeply into a room, while the air-guiding sections of the air flow, which are out exits the outlet slots, gives a swirl, which engages in the vertical air flow of the openings and deflects them. This significantly improves induction into the room. It is essential, however, that the additional air flow emerging from the annular gap results in a large-scale escape of the air along the installation plane, ie mostly along a ceiling. Such an escape of air favors a uniform, draft-free and large-area introduction of warm or cold air into the room, while increasing the air volume flow.
- a ring of apertures around the outlet slots around are arranged not only the openings between the outlet slots, 'but there is a ring of apertures around the outlet slots around. If the outlet disk 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 breakthroughs quasi creates a cylinder-shaped 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 air can also enter the room more freely through the openings in the ring around the outlet slots.
- the air emerging from the openings with a smaller diameter is entrained by the swirl flow, but pulls the swirl flow down into the room.
- FIG. 1 shows a plan view of a swirl outlet according to the invention
- FIG. 2 shows a cross section through the swirl outlet according to FIG. 1 along the line II-II;
- FIG. 3 shows a side view of an air guidance system with the swirl outlet according to FIG. 2;
- FIGS. 4 and 5 side views of further exemplary embodiments of air guidance systems with the swirl outlet according to FIG. 2;
- a swirl outlet R according to the invention has an outlet disk 1, which is encompassed by an edge strip 2 which is curved outwards in a funnel shape.
- outlet slots 12 are formed in the outlet disk 1.
- these outlet slots 12 have different lengths l ⁇ and I2.
- openings 13 in the outlet disk 1 between the outlet slots 12 which are shaped as round holes in the present exemplary embodiment.
- all other geometric shapes for example angular, elliptical, teardrop-shaped, etc. holes are within the scope of the invention.
- the openings 13 do not all have the same diameter, but can be shaped differently.
- the air outlet louvers 14 are assigned to the outlet slots 12. These air guide fins 14 are preferably rotatably mounted on an axis 15, the axis 15 extending between two bearing disks 16 and 17.
- the bearing disks 16 and 17 can be punched out of the material of the outlet disk 1 during the punching operation for the outlet slots 12 and bent upwards. Other definitions for the bearing disc are also within the scope of the invention.
- the bearing disks preferably have a foot web 18, which forms a groove 12 or 13 on both sides toward the bearing disk 16 or 17.
- the bearing disk 16 or 17 can then be inserted into the outlet slot 12 and rotated until the marginal edges of the outlet slot 12 each enter the groove 19. This simplifies the setting of the air guide fins 14 and no additional welding spots or the like fastenings are required.
- the outlet disk 1 is connected to an air-supplying, funnel-shaped element 3 via a fastening element 4, which is inserted into the wall openings 5a and 5b of the funnel-shaped element 3 with a possibly aerodynamically designed cross member 5 and axis extending transversely to the funnel-shaped element 3.
- the cross member 5 has cutouts 7, a sleeve 8 being inserted into one of the cutouts. This serves to receive the fastening element 4. If the fastening element is designed as a screw, the sleeve 8 has a corresponding internal thread. End pieces 9 are pressed into the crossmember 5 from the outside and serve to fix the crossmember 5.
- annular gap 10 (max. 360 °) is formed between the funnel-shaped edge strip 2 and the air-supplying element 3 by spacers 11. These spacers can be exchanged for longer or shorter ones as desired. This determines the width of the annular gap 10 and thus the amount of air to be discharged. It is also possible to form threaded sections onto the element 3 and the edge strip 2, it being possible for a distance between the two threaded sections to be adjusted by means of a threaded sleeve. The fastening element 4 can also change the distance b.
- the funnel-shaped and air-supplying element 3 lies with its outer edge of a ceiling 6 according to FIG. 5 from below.
- the annular gap 10 is located directly below the ceiling 6, so that part of the air is discharged horizontally from the annular gap.
- FIG. 5 is via a distribution box 20 with a lateral connection piece 22, while according to FIGS. 3 and 4 either a straight pipe 23 or a flexible pipe 24 with a bend is pushed onto the funnel-shaped element 3.
