Air distribution device and method of adjusting the air distribution device Luftfördelningsanordning och forfarande vid regiering av luftfördelningsanordningen 5

The invention relates to an air distributor and a method for adjusting an air distributor.

DE patent 3 410 078 discloses a supply air solution in which the apparatus comprises fixed circumferentially arranged wings which are fastened to a central core tube. In the device solution, the air flow through the device is controlled by moving the valve plate at the end of the core tube simultaneously with the second controller. The second regulator consists of a locking ring. Thus, in the solution according to DE 3 410 078, the position of the first and second controllers is adjusted simultaneously.

Our application presents an improvement over prior art constructions. The invention uses a wing ring fixedly connected to an outer tube comprising a curved collar. The flow control vanes are thus fixedly in a constant position relative to the outer tube comprising the collar. The adjustable airflow control is provided by a separate movable cylinder tube adapted to be located between the outer tube of the fixed impeller and the outer tube of the device. When said cylinder tube to be positioned is in its lower position, the airflow control is made to operate in such a way that the air flowing through the vanes of the impeller flows as far as possible as far downwards as possible and no airflow is applied to the side. While the cylinder tube is in the up position, the vanes, together with the curved collar of the outer tube, then direct the flow to the side and thus the flow distribution to the room is at its maximum.

In a further embodiment of the invention, a separate flange is used, which extends inwards from the outer tube comprising the curved collar, whereby the cylinder tube can be positioned relative to and against said flange. Thus, when the wing tube is positioned in the highest possible position, it rests against the annular flange and completely shuts off the side flow. Within the scope of the invention, an embodiment is also possible in which the side flow is prevented in all positions. In this case, the impeller is constructed from its outermost tube in such a way that it comprises an annular flange which is attached to the tube having the outer curved collar S of the device. In this embodiment, the cylinder tube is controlled in the same way as in the previous embodiments. The forks associated with the cylinder support then extend through the openings in the ring flange, making it possible to control the cylinder tube.

The invention is characterized by what is stated in the claims.

The invention will now be described with reference to some preferred embodiments of the invention shown in the figures of the accompanying drawings, to which, however, the invention is not intended to be exclusively limited.

Fig. 1A shows diagrammatically and in an axonometric view an air distributor 10 according to the invention. As shown in the figure, the air distributor 10 comprises a tube or outer jacket 12b comprising an outer curved collar 12a, to which a wing 11 from its outer jacket 1 . Air is flowed by means of fans or other devices from the ductwork 30 through the air distribution device 10 acting as the air distribution terminal member, so that the air flows through the air control vanes 11a, 11a2 ... into the room space in a spiral manner. Thus, the 4 99277 air control vanes 1 1a |, 1 la 2 --- make the air move in a helical downward direction, whereby the fresh air / heated air or other air introduced into the room is efficiently transported into the room.

Fig. 1B shows a device 10 according to the invention, mainly in section I-I of Fig. 1A. The air flows into the room through the air deflectors 11a1, 11a2 ... of the wing circumference 11 (arrow Lj). The air guide vanes 11a, 11a2, 11a3 ... are connected to the central shaft 11b and at one end to a wider wing circumferential tube 11c. The wing circumference 11 thus further comprises an outer tube 11c, of which the wing circumference 11 with its associated wing structures 10 species, 11a2- .. and shafts 11b is connected to the tube of the collar 12a, i.e. to the outer jacket of the device.

According to the invention, there is a separate cylindrical tube 13 with a circular cross-section to be mounted between the collar 12a and the tube 11c of the wing circumference 11. The cylinder tube 13 is connected to a cylinder support 14 to which a central sleeve 15 is connected. . Inside the hollow shaft 11b of the sleeve 15 and the second sleeve 16 there is a screw 17 parallel to the central axis (X axis) of the device, which is connected at its end by a mounting flange 18. The screw 17 is surrounded by a spring 19. The spring 19 is fitted to the sleeve 16b between. When the screw 17 is rotated, its threads J1 engage with the opposite thread J2 in the end hole 15b of the sleeve 15. Thus, by turning the screw 17 from the flange 18, the cylinder tube 13 (arrows S1 and S2) is raised and lowered so as to be brought to the desired air guide positions with respect to the fixed wing 9 and the wings 11a2 ... fixed to the collar 12a. with respect to the tube 12b. Nuts Mj and M2 determine the operating range of the device; permissible movement for the cylinder tube 13.

Figure 2B shows the steering cylinder 13 in an upper position relative to the fixed wing 11. In this case, the air flow Lj through the wings 1 lat, 1 la2 ... of the wing circumference 11 into the room space spreads laterally under the guidance of the curved surface of the collar 12a.

Figure 2B shows the lower position of the airflow control cylinder. In this case, the airflow

Lj through the blades 1, 1___ is guided directly downwards under the control of the inner surface of the cylinder tube 13.

5 2C shows the direction the apparatus of Figure 2A, Figure 2A arrow K. As shown in the figure, the wing ring 11 itself is connected by screws R1, R2 ... to a fixed position with respect to the tubes 12b of the collar 12a.

Figure 3A shows the cylinder support 14, the cylinder tube 13, the collar tube 12b and the impeller 11 to be mounted in a fixed position 10, separated from each other. As shown in the figure, the cylinder support 14 comprises rib-like branches 14alt14a2 ... connected to an air flow controlling cylinder tube 13, the side surface of which has upwardly open grooves whereby the cylinder support 14 can be moved so that the cylinder tube 13 moves vertically and the wing mounting screws Rj ... in said upwardly open 15 grooves Uj.U ^ .. (grooves U2 ... shown in Fig. 4B). This allows the cylinder tube 13 to move inside the collar 12a and the tube 12b associated with the collar 12a, i.e. the collar tube, and outside the wing circumferential tube 11c of the wing circumference 11.

Figure 3B shows a separate view of the cylinder support 14 and the cylinder tube 13. As shown in Fig. 20B, the cylinder support 14 associated with the tube 13 comprises branch portions Ma ^ Ma ^ .. associated with the support body 14b which engages the sleeve 15.

Figure 3C is a top view of the device of Figure 3A. As shown in Fig. 3C, it can be seen that the cylindrical tube 13 is a circular cylindrical hollow part which is fitted 25 to surround the tube 11c of the wing circumference 11.

Figures 4A and 4B show another embodiment of the invention with a separate inner flange 20 of the outer tube 12b, whereby when the cylinder tube 13 is moved to the upper position the side flow L2 is completely closed and the whole air flow Lj passes through the vanes 301, 11a2 ... Branches 14a1,14a2 of the support part 14 of the cylinder tube 13 ...

pass through the through holes 22aj, 22a2 ... of the flange 20. The action is now as follows.

6 99277

When the air flow cylinder tube 13 is in the up position, the air flow Lj passing through the wing blades 11a 2 ... is directed laterally under the direction of the collar 12a and at the same time the side flow path Lj is closed (preventing any flow from the outer tube 1le and the collar 12a). When the airflow control part, i.e. the so-called

5 the cylinder tube 13 is set to extend below the impeller 11, its function being to direct the flow Lj coming through the vanes of the impeller 11 downwards. In this embodiment, a side flow between the wing ring 11c of the impeller 11 and the tube 12b of the collar 12a is then also allowed, said side flow L2 acting as a downward curtain jet and further facilitating the direct flow of air flow 10 downwards.

Fig. 5 schematically shows an embodiment otherwise corresponding to Figs. 4A and 4B, but in the solution shown in Fig. 3, the wing circumference 11 is located in a fixed position with respect to the annular flange 20. In this case, the side flow L2 is always blocked and the air IS flows (arrow Lj) only through the wings 11a1, 11a2 ... of the impeller 11.

Fig. 6 shows an embodiment of the invention closest to Fig. 5, in which the impeller 11 is connected to the annular, circumferential flange part 20 via separate suspension hooks 21aj, 21a2 ... the outer impeller tube 11c of the impeller 11 is attached to the flange part 20 or the impeller flange 1 taiveen.

Fig. 7 shows an embodiment of the wing ring 11, in which the wing ring 11 comprises two separate wing groups, i.e. wing groups D1 and D2. Within the scope of the invention, it is of course possible that there are one or more wing groups DJtD2 .... As shown in the figure, the inner wings 11a ', 11a' 2 of the wing group Dj are connected at one end to the shaft 11b and at the other end to the wing tube 11c *. The wings 11a1a, 11a2 "... associated with the wing group D2 are connected at one end to the wing tube 11c 'and at the other end to the outer tube 11a, which further joins the outer device tube 12b comprising the collar 12a by screw means Rj, R2 ... Figure 7 shows the wing ring 11 30. The wings 11a1, 11a2 ...; 11aj, 11a2 '... ;llaj ", 11a2" ... project radially from the central axis X over the entire circumferential region and distance.
