Device for ventilating and, if necessary, de-ventilating a room

The invention relates to a device for ventilating and, if necessary, also de-ventilating a room by means of individual nozzles, which are arranged in a housing box.

Nozzles are known which can be adjusted as individual nozzles either by a servomotor or by hand. These individual nozzles are used to supply warm or cold air to a room. The disadvantage of these individual nozzles is the considerable installation effort, since each individual nozzle must be assigned a motor or each individual nozzle must be adjusted manually.

The inventors have set themselves the goal of developing a device of the above-mentioned type, by means of which the introduction of fresh air into a room can be controlled much better and whose installation is easier.

This problem is solved by rigidly inserting at least one individual nozzle into a nozzle grid and arranging the latter so that it can pivot relative to an axis of the housing.

Firstly, there is the advantage that the individual nozzle itself does not have to be adjusted, but the adjustment is made via the nozzle grille. Furthermore, it will usually be the case that several individual nozzles are combined in a nozzle grille, so that when the nozzle grille is adjusted, several individual nozzles are always adjusted. In a ventilation grille designed in this way, several nozzle grilles with several single nozzles can be used in individual rows or consecutive rows. All of these grilles or only certain ones of them can be adjusted together using a servomotor. For example, pivoting from the longitudinal axis is possible when the ventilation grille is installed in the wall.

For cold air, however, the nozzle axes are directed towards the ceiling so that no draughts occur.

With this ventilation grille, the operator has the advantage that the incoming fresh air reaches the interior of the room relatively safely and the room is flushed very well. Using the relevant diagrams, the user of the system or an appropriate installer can determine which throw distances he can safely achieve with the nozzles. The individual nozzle grilles are also supplied with nozzles of different nozzle diameters, so that practically any desired depth of room can be filled with fresh supply air without any problem. Of course, this also depends on the amount of air supplied. The nozzle grilles are very quiet and can let out a considerable amount of air.

Preferably, a nozzle grille consists of a frame strip which is adapted to the inner contours of the housing box. If only a swivel from the longitudinal axis of the housing box is desired, this frame strip is not fixed laterally. However, a rotation of the nozzle grille around the longitudinal axis of the housing box should also be possible and should be covered by the present inventive concept. In this case, the housing box then has a lateral bulge so that swiveling of the nozzle grille around the longitudinal axis of the housing is not hindered.

The frame strip preferably encloses plates into which the individual nozzles are inserted and to which the individual nozzles are firmly connected.

In the present embodiment, the nozzle grille is connected to the housing box via fastening tabs, whereby these fastening tabs are opposite one another and form an axis of rotation for the nozzle grille.

In this way, the grille can be adjusted up or down very easily and simply .

A servomotor is a good option for swiveling the nozzle grid. Of course, swiveling is also possible manually, whereby the nozzle grid is then preferably fixed in a certain position. A relatively large number of individual nozzles can be adjusted using a single drive or manually, which means that there is a significant saving in assembly costs and power consumption.

In a further embodiment of the invention, the nozzle grilles are partially interspersed with air slots. This makes it possible to extract exhaust air from a room without disturbing the supply air. The nozzles throw the supply air relatively far into the room so that no short circuit occurs, i.e. no direct discharge of the supply air. With conventional grilles, the entry speed is too low to allow such a combination of supply and exhaust air grilles.

Naturally, this ventilation grille according to the invention is suitable for both wall and ceiling installation. It can be used with or without ball protection in any length or width.

Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawing, which shows in

Fig. 1 is a front view of a ventilation grille according to the invention;

Fig. 2 shows a cross-section through the ventilation grille according to Figure 1;

Fig. 3 shows a cross section through another embodiment of a ventilation grille corresponding to that shown in Figure 1.

According to Figure 1, a ventilation grille 1 has a grille frame 2, which essentially consists of cover strips 3 and an approximately rectangular housing box 4. The cover strips 3 surround the housing box 1 as a collar. This grille frame 2 is installed, for example, in a wall or a ceiling (not shown in more detail).

According to Figure 2, the housing box 4 has side walls 6 which are flat over their entire surface. Figure 3, on the other hand, shows a housing box 4a with side walls 6a which partially have bulges 7.

Nozzle grilles 5 and 5a are inserted into the housing box 4 and 4a respectively. Each nozzle grille 5 and 5a respectively has a frame strip 8 by means of which the nozzle grille 5 and 5a respectively is supported against the side walls 6 and 6a respectively.

In the embodiment according to Figure 3, the nozzle grille 5a is located in the area of the bulges 7.

The nozzle grilles 5 and 5a are connected to the housing box 4 and 4a via front fastening tabs 9, which have a hole 10, for example, for receiving a corresponding screw or rivet. These holes 10 simultaneously form a pivot bearing, whereby the inclination of the nozzle grille 5 and 5a can be changed within the housing box 4 and 4a.

Approximately square plates 12, which have a central recess 13, are connected to the frame strip 3. Individual nozzles 14 are inserted into the recess 13 and connected to the plate 12 via corresponding screws 15. Preferably, several such individual nozzles 14 are provided for a nozzle citter �X.

In Figure 1, the arrangement of exhaust air slots 16 is also shown, whereby a separate supply of the supply air to the individual nozzles 14 and removal of the exhaust air from the exhaust air slots 16 connects to the housing box 4 or 4a.
