Definitions
- the invention relates to a swirl diffuser, for ventilating rooms, having a housing which has an inlet air nozzle and an outlet opening, in particular quadrangular, front passage, wherein in the front passage a plurality of passage openings are provided and the front passage upstream of each passage opening one of the respective passage opening assigned comprises air guide element designed as a swirl blade.
- Twist outlets are usually arranged in or below ceilings and are connected by means of Zu Kunststoffstutzens to a ventilation system.
- the air is introduced into the space to be ventilated by the radial arrangement of the swirl blades. This room air is induced.
- the disadvantage is that isolated no sufficient swirl effect and thus not the desired induction can be achieved.
- the object of the invention is to avoid the aforementioned disadvantages and to provide a twist outlet, by means of which a greater swirl effect can be achieved.
- each air guide is curved as seen in the flow direction that the air guide elements are seen curved in their longitudinal extent and that the average angle ⁇ of each air guide along the longitudinal extent of the air guide element is different in size and from the center facing away from the end to the middle-facing end of the air guide element, preferably continuously increases, the angle of attack ⁇ between the general plane E of the front passage on the one hand and a straight line G on the other hand and wherein the straight line G between the inflow edge and the downstream edge of the air guide element runs.
- the center of the front passage may also be formed as a central region.
- the air guide elements are curved as seen in the flow direction, so that thus the course of an air guide from its upstream edge to its downstream, d. H. room side, edge becomes increasingly horizontal.
- the air guide elements are seen curved in their longitudinal extent. Under the longitudinal extent of the air guide elements, the course of the relevant air guide element from the outer edge region of the front passage to the center and vice versa, understood. Thus, the front passage in the plan view receives an appearance like a vortex or a spiral.
- each air guide element from the outer edge region of the front passage to the middle on a torsion increase.
- the angle of attack ⁇ may be about 20 ° to 28 °, preferably 24 °, in the region of the end of the air guiding element facing away from the center.
- the angle of attack ⁇ in the region of the center-facing end of the air guide element about 30 ° to 40 °, preferably 36 °, amount.
- the width B of at least one passage opening may be smaller than the projection P of the air guide element assigned to this passage opening.
- the air guide elements can be formed integrally with the front passage. In this case, between two adjacent passage openings in each case a web-shaped intermediate region in the plane of the front passage, on which at least one air guide element is articulated.
- the front passage is made of plastic.
- the front passage can be manufactured, for example, by means of an injection molding process.
- Other materials, such as sheet metal, are of course possible.
- a front passage 1 of a swirl outlet according to the invention is shown. With the inflow side of the front passage 1 is mounted on a housing, not shown, which has a Zu Kunststoffstutzen, via which the housing is connected to an air conditioning system.
- the front passage 1 has a central region 2.
- a central bore 3 is provided, through which a fastening means, not shown, for fastening the front passage 1 to the housing can be inserted.
- the central region 3 can be covered by a suitable cover. If the cover element also has openings through which air is to be conducted into the room, air supply openings 4 are provided in the middle area.
- each passage opening 5 is assigned a designed as a swirl blade air guide 6.
- the front passage 1 has a round outer contour.
- the air guide elements 6 are, as in Fig. 1 recognizable seen in its longitudinal extent, curved, so that the front passage 1 receives a look in the manner of a spiral or a vortex.
- each air guide element 6 is curved in the direction of flow 7, so that the course of an air guide element 6 from its upstream edge 8 to its downstream, ie room-side, edge 9 is increasingly horizontal.
- the angle of attack ⁇ of each air guide element 6 along the longitudinal extent of the air guide element 6 is different in size and increases from the middle end facing away from the middle region 2 facing the end of the air guide element 6.
- the angle of attack ⁇ lies between the general plane E of the front passage 1 on the one hand and a straight line G on the other hand, the straight line G extending between the upstream edge 8 and the downstream edge 9 of an air guide element 6.
- the width B of a passage opening 5 is smaller than the projection P of the air guide element 6 assigned to this passage opening 5.
- the front passage 1 has a circumferential edge strip 10 which surrounds the outside of the passage openings 5 and the air guide elements 6.
- a circumferential collar 11 is provided on the upstream side of the front passage 1. With its respective end facing away from the central region, each air guide element 6 touches the collar 11.
