Definitions

the invention relates to an air outlet for introducing warm and / or cold air into a room through an outlet connection, which is covered by a perforated plate.
Such air outlets are of various shapes and designs known and in use on the market. You serve in addition, air, which via a duct system or air supply systems is transported into a room. As Example is based on the German utility model DE 87 13 209.5. There can be various for discharging the air Perforated sheets must be upstream of an outlet.
the present invention is therefore based on the object an air outlet of the above Kind of creating which with the simplest of means the air flow in the simplest way influences and regulates.
a good mix with Indoor air is said to reduce at the same time Drafts take place.
the perforated plate with a cover ring or a diffuser.
the air guide socket is also preferred Long throw element assigned.
the long throw element can be a nozzle or a tube, which is preferably guided in the air duct and forms a long throw device with it.
the air duct connection has a cylinder collar which a funnel connects, which in turn is in a cover ring transforms. This lies in one level of the perforated plate of the air outlet.
the axial is essential in the present invention Moving the tube back and forth, which is preferred in the cylinder collar of the air duct is guided. It can the tube is completely moved out of the funnel area or into the funnel up to the level of the perforated plate will. The airflow is in this retracted position spread vertically down into a room.
the tube will go towards the cylinder collar retracted, the vertical flow goes down into a swelling flow, which has a lower penetration depth, but a wider horizontal distribution of the air flow.
This process of the pipe can be on manual and / or pneumatic, hydraulic and / or electrical way.
the air flow that passes through between the outlet port and air guide socket formed annular gap horizontally can be distracted by choosing the width of the cover ring be influenced quantitatively.
This support jet can be reduced continuously, when the tube is moved back in the cylinder collar. So changed the support beam continuously swells into a Airflow at reduced speed, accordingly the air flow emerging laterally from the annular gap.
the scope of the present invention also lies other conceivable ways of using such pipes
To influence air flows in the funnel area
the shape of the funnel can be designed in a laval nozzle shape be.
Also differently trained in cross-section Pipes can be used here. It is also in one different inclination and in particular to a different one flow-influencing profiling of this Funnel thought. So influence can be achieved with the simplest of means on the flow through the annular gap and on the Flow through the outlet opening of the air duct flows, to be taken.
the Air duct socket Extracted air from a room.
an air outlet R has a perforated plate 1, which is preferably square is trained.
the perforated plate 1 is an outer funnel-shaped outlet nozzle 2, which is shaped like a diffuser. You can Perforated plate 1 and outlet 2 also other, for example. square, rectangular, round, oval shapes to from the outside to a desired appearance gain.
the outlet nozzle 2 is a long throw device 5 intended.
This has an air duct 3, in which is a long throw element designed as a tube 4 axially is slidably arranged.
the air duct 3 and the tube 4 together form the throwing device 5 for Regulate and adjust different air flows.
the outlet connector 2 has an air inlet opening 6, through which fresh air enters the air outlet R. In the middle a further inlet opening 7 is formed by the tube 4.
the operation of the present invention is as follows: The air flows through the funnel-shaped outlet connection 2 and passes through one in the plane E of the perforated plate 1 formed annular gap 8, which between the air duct 3 and the outlet nozzle 2 is formed.
the flow-influencing air duct 3 has a cylinder collar 9, which in an expanding Funnel 10 and this merges into a cover ring 11. This is directly connected to the perforated plate 1.
a transition between funnel 10 and cover ring 11 is preferably aerodynamic and possibly curved, with radii provided, trained.
the cover ring 11 has a width B, which may through additional cover rings or wider ones Cover rings is changeable. Within the cover ring 11 is an outlet opening 12 in the plane E of the perforated plate 1 formed, which is larger than the inlet opening 7 of the Tube 4 is.
Tube 4 within the air duct 3 steplessly in an opening 9.1 of the cylinder collar 9 is axially movable.
the tube 4 is inside the cylinder collar 9 guided.
Adjustment elements not shown here can this pipe 4 manually and / or pneumatically / hydraulically and / or axially stepless in the longitudinal direction adjust.
the tube 4 is in a retracted position shown.
the supply air passing through the inlet opening 7 can expand in the funnel 10 and is then spread into a room through the outlet opening 12.
Of the escaping airflow has no high due to the expansion More speed and almost oozes from the perforated plate in the Area of the outlet opening 12. This is what happens no drafts.
the tube is in a further position of use according to FIG. 3 4 shown in the direction of the plane E of the perforated plate 1 shifted. This results in a continuously reduced possibility the expansion of the air flow passing through the tube 4. Is the tube 4 fully extended and lies on the perforated plate 1, the air flow is far down in spread a space vertically as a support jet.
this support jet is no longer desired, just need the tube 4, as described above, up into the cylinder collar 9 or to be moved into the funnel 10, so the speed then slows down and on swelling air flow can emerge from the funnel 10.
the air flow from the annular gap 8 is no longer carried along, so that it exits and extends diagonally to horizontally For example, can create a ceiling. This gets the air much slower in the room.
the interaction in particular between the air currents is crucial.
the tube 4 is usually round. Within the scope of the present invention however, there are also other profiles of the adjustment tube 4, such as. Rectangular, oval or other shapes, where according to the shape of the tube 4 then air duct connection 3 with cylinder collar 9, funnel 10 and cover ring 11 are trained.
the throwing element 4 is connected to a suction device so that no air is discharged, but exhaust air is led out of the room. Between outlet port 2 and Long throw element is still supply air into the room spread, due to the outward facing Flow, however, is not a "short circuit" between supply and exhaust air arises.
the supply air is introduced laterally into an annular chamber 17 in the air outlet R1 shown.
