Abstract

The invention relates to an arrangement having an intake air device (1) comprising a diffuser in the form of a cylinder casing (1a) which is at least partially perforated. At one end, it can be connected to a fresh air duct (2) and, at the other end, has an endpiece (1a1). Along substantially its entire length the cylinder casing (1a) has a shield which covers part of the periphery of the casing and of which the position can be adjusted about the cylinder axis. The shield is rigid relative to the cylinder casing (1a) and the latter is in turn rotatable about the above-mentioned axis, thus rendering the position of the shield adjustable.

Description

Device at a make up air apparatus
The present invention relates to an arrangement with an intake air device comprising a partially perforated cylinder casing which at one end can be connected to an intake air duct and which comprises at the other end an endpiece and which along substantially its entire length has a section which covers part of the periphery of the casing and is adapted to prevent the through-flow of air and of which the position can be adjusted about the cylinder axis.
Such an intake air device was previously disclosed by EP 269 923 A2 and comprises a shield which is disposed on the cylinder casing and which is rotatably mounted so that it can move around the casing, about the centre axis thereof. The shield is consequently fully visible, which can be advantageous if the installed position thereof has to be checked but, at the same time, this places high demands on fitting and surface finishing in order that the aesthetic appearance of the intake air device is not impaired. The ability of the shield to rotate about the cylinder casing also necessitates precision manufacturing - the shield must be easy to adjust and has an unnecessarily complicated construction.
The object of the present invention is to provide an intake air device of the initially mentioned type which does not involve the above disadvantages. This object is achieved in that the section is rigid relative to the cylinder casing, and in that the latter is in turn rotatable about said axis.
Preferably, in order to prevent the throughflow of air, the above-mentioned section is a shield which is rigidly disposed inside the cylinder casing and near the inner surface thereof such that it fits against the latter, although the section can also, alternatively, be an unperforated portion of the cylinder casing, as depicted by special features of the invention.
In the following, the invention will be described in greater detail with reference to the enclosed drawings, in which:
Figure 1 is a perspective view showing schematically an embodiment of the intake air device according to the invention;
Figures 2a show sections of detail views which illustrate in and 2b perspective the above-mentioned section provided with a shield and with an unperforated periphery, respectively; and
Figures 3a show intake air configurations in different to 3f positions of the section on a wall mounting (Figures 3a - 3c), corner mounting (Figures 3d - 3e) and in a free-standing arrangement (Figure 3f), respectively, of the intake air device.
In the drawings, 1 generally designates an intake air device according to the invention. It comprises a perforated cylinder casing la. It should be noted that the drawings only show some of the perforations, for the sake of simplicity. The cylinder casing la can be connected at one end to an intake air duct 2 and, at this end, is formed with a wall attachment 3. At the other end, the cylinder casing has an endpiece lal.
The intake air device 1 has a section which is adapted to prevent the throughflow of air and which extends along the length of the cylinder casing la and covers part of the periphery of the casing. In accordance with the invention, this section is rigid relative to the cylinder casing la, which is in turn rotatable about its centre axis. The ability to rotate is due only to the fact that the intake air device, in a conventional manner, is inserted and rotatable in a shoulder 4 which is connected to the intake air duct 2 and which is held rigid by the wall attachment 3.
As illustrated in Figures 2a and 2b, the section which is adapted to prevent the throughflow of air can be an unperforated portion la2 of the perforated cylinder casing la or a shield lb which is formed such that it fits against the inner surface of the cylinder casing la and is rigidly disposed relative to this casing.
Figures 3a to 3f illustrate the intake air configurations for various alternative mountings for the intake air device according to the invention. In the case of the wall mountings shown in Figures 3a to 3c, the section is disposed at the rear in Figure 3a, at the front in Figure 3b, and at an angle at the front and to one side in Figure 3c. In the case of the corner mountings according to Figures 3d and 3e, Figure 3d shows the intake air configuration with the section disposed closest the corner and Figure 3e shows the corresponding intake air configuration with the section disposed away from the corner. Finally, Figure 3f shows the intake air configuration in the case of a free-standing intake air device with the section disposed at an angle at the top right-hand side in the Figures.
In conclusion, it can be stated that the intake air device according to the invention provides the desired intake air configuration in a simple manner. It will be appreciated that the intake air device requires some form of marking to indicate the position of the section, which applies in particular to the example according to Figure 2b.
