Description

The invention relates to a device for introducing and / or discharge of air in / from a / m room with a housing having an air inlet and an air outlet, wherein in an interior of the housing, a deflection device for the air is provided.

State of the art

Such devices for guiding air in air conditioning systems are known in a variety of forms and designs and on the market. For example, the German utility model shows 73 22 128 a sound-insulating airlock for living spaces od. Like., Which consists of a channel-like housing with inlet and outlet openings for the airflow to be passed through and workshop is completed. The air gives in Interior of this airlock a diversion and is passed by insulating layers, which take over the sound insulation.

A device of the type mentioned above is from DE 42 32 315 A1 known. There, the Zulufteinrichtung consists of a cuboid housing that is intended for installation in the outer walls of buildings and / or apartments. In the housing there is a cross-sectionally approximately S-shaped Luftumlenkkanal, which is lined with sound and heat-insulating material, and through which air can flow from the outside to the interior of the apartment.

Next is in the FR 2 523 190 the preamble of claim 1 discloses.

task

The object of the present invention is to provide a device which has excellent insulating properties and is easy to manufacture. Furthermore, their stability should be substantially improved and installation in lightweight walls possible.

Solution of the task

To achieve the object, the features of claim 1.

The production of the housing from two shells has the advantage that the interior of the housing can be covered with the corresponding insulating layers. Furthermore, a separate production of the deflection is possible, which is connected only after their production with the two shells. As a result, the two shells can be decoupled from each other, so that a vibration acting on a shell has no effect on the other shell. Furthermore, the connection of deflecting device and shells can be configured such that the deflecting device contributes substantially to the stability of the entire housing.

This purpose is mainly used when flanges are folded from the shells, which can lie flat against each other during assembly. These flanges can then be separated by inserting appropriate insulating strips.

Above all, however, it is envisaged that the circumferential flanges also accommodate the plate-shaped deflection between them, so that the plate-shaped deflection counteracts a distortion of the shells. It contributes significantly to the stabilization of the entire housing, so that this always retains its desired shape.

Depending on the volume of air to be delivered, it may be advisable that air flows around the diverter only on one side. If more air volume to be promoted, it is possible to arrange the deflection so in the interior of the housing that flows around two or three sides.

Preferably, the plate-shaped deflection device consists of two panels, between which at least partially an insulation is arranged. Among other things, this insulation can consist of a heavy foil. Here, heavy foil is understood as meaning a foil having a high basis weight of, for example, 3 kg per square meter.

The deflection should be at least partially occupied with insulation. Here, for the sake of simplicity, a melanin resin layer is available, although other sound-insulating materials are also conceivable.

A special eye feature is to be directed to the fact that the plate-shaped deflection device, however, is preferably not covered with insulation in the visible area of the air inlet or air outlet, but is coated there with the same color, for example white, like the air inlet or air outlet. For example, architects today want to see smooth, white surfaces, also inside an airlock. By means of the deflection device according to the invention, the best possible optical sealing protection is obtained. Looking through or shining light from a hallway into rooms or vice versa is prevented.

The interior of the housing itself should also be lined with insulation. Here too, a melanin resin layer is especially suitable.

In a preferred embodiment of the invention, a deep absorber for low frequencies is provided at the bottom of the interior. This can also consist of a melanin resin layer, which, however, has a greater thickness.

In a preferred embodiment of the invention, both shells can be identical, so that the air inlet and outlet are the same and are also at the same height. As a result, the manufacturing costs are reduced.

To improve the sound also contributes, if the wall thickness of the shells have a different thickness. In this case, the shells are subject to a different vibration, so that a transmission of the vibrations to each other is excluded.

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

FIG. 1

a plan view of an inventive device for introducing and / or discharge of air in / from a / m space;

FIG. 2

a longitudinal section through the device according to FIG. 1 along line II-II in the position of use and in slightly modified form;

FIG. 3

a longitudinal section through a further embodiment of an inventive device for introducing and / or discharging air in / from a / m space.

A device according to the invention for introducing and / or discharging air into / out of a / m has according to FIG. 1 a housing 1, which has a slot-shaped air outlet 2 and an air inlet indicated only by dashed lines. The embodiments according to the FIGS. 1 and 2 differ in that the air intake 3 after FIG. 1 is designed as an air inlet, while an air inlet 3.1 according to FIG. 2 is configured identically with the slot-shaped air outlet 2.

The housing 1 is according to FIG. 2 from two shells 4.1 and 4.2, which together enclose an inner space 5. In the interior 5, a deflection device 6 is used, which is designed plate-shaped. It consists of two panels 7.1 and 7.2, between which some heavy foil 8 and partially insulating strips 9 are inserted. In the area of the interior 5, the panels 7.1 and 7.2 are externally covered with a melanin resin layer 10.1 and 10.2.

The interior 5 of the housing 1 is laterally also covered with a melamine resin layer 11.1 and 11.2, at the bottom there is a depth absorber 12, preferably also a melamine resin strip, which, however, is designed substantially thicker.

In the embodiment according to FIG. 2 the two shells 4.1 and 4.2 are identical. In FIG. 1 can be seen that laterally in the shell 4.1 - and thus also in the shell 4.2 - circumferential flanges 13.1 to 13.4 are folded. About these flanges 13.1 to 13.4, the shell 4.1 is connected to corresponding flanges on the shell 4.2, wherein the flanges, unless the baffle 6 is disposed therebetween, separated by insulating strip 14 to each other. They are od by any configured fasteners 15, such as screws, rivets. Like. Connected to each other. These fasteners 15 are, for example, supported by a foam rubber seal or other elastic documents.

The operation of the present invention is as follows:

The preparation of the inventive device is carried out in a simple manner by corresponding punching and folding of the shells 4.1 and 4.2 with the flanges 13.1 to 13.4. Since the shells are still open after manufacture, they can readily be covered with melanin resin layers 11.1 and 11.2.

Likewise, the deflection device 6 is produced separately, in which between the two panels 7.1 and 7.2, the heavy foil 8 and the corresponding insulating strips 9 are inserted.

When connecting the two shells 4.1 and 4.2, the deep absorber 12 is inserted in the interior 5 below, also the deflecting device 8 is inserted between the flanges 13.1, 13.2 and 13.3 and connected there with the flanges via the corresponding fastening means 15. This gives the Housing 1 a very high rigidity, so that a consistent shape of the device is guaranteed in each case, which is desirable on-site.

Further, both shells 4.1 and 4.2 are decoupled from each other by the insertion of the insulating strips 14 between the flanges so that one shell 4.1 can oscillate without affecting the other shell 4.2 thereof or vice versa.

The plate-shaped deflection device 6 is preferably not covered with a melanin resin layer in the visible range of the air outlet 2 or air inlet 3 or 3.1, so that in this area the panel 7.1 or 7.2 can be colored with the same color as the air outlet or the air inlet , This offers the viewer a smooth, barely noticeable surface. This applies in particular to a white coloring of the shells 4.1 and 4.2 and the deflection device 6 in the field of vision.

The device according to the invention is intended to be used in particular for lightweight walls with high acoustic requirements. In FIG. 2 it can be seen that the housing 1 is inserted into a lightweight wall made of an inner and outer gypsum plasterboard wall 16.1 and 16.2. The housing 1 is supported against the plasterboard shells 16.1 and 16.2 via insulating strip 17, so that the housing 1 is decoupled from the lightweight wall. The same applies to the air inlet 2 and the air inlet 3.1, in which case the insulating strips are not marked in detail.

Furthermore, for visual reasons, the air outlet 2 and also the air inlet 3.1 each comprise a surrounding frame 18.1 and 18.2.

The air, which now flows through the air inlet 3.1 into the interior 5, is deflected by the deflecting device 6 and damped by the melamine resin layers 10.2 and 11.2. The deep absorber 12 takes over the sound insulation of depth frequencies.

A further insulation of the air bar is carried out by the melanine resin layers 10.1 and 11.1 when guiding the air in the direction of the air outlet 2.

The inventive device is particularly suitable for installation in lightweight partition walls with particularly high demands on the Bauschalldämm Mass R'b 32 to 50 dB for single-shell partitions and 58 dB for two-shell partitions according to DIN 4109. Despite the excellent sound insulation, only a slight pressure loss is noted, which is particularly noteworthy.

In addition, the device can still be provided with a corresponding fire protection equipment (F90 as an option).

The embodiment of the device according to the invention for introducing and / or discharging air according to FIG. 4 basically represents a doubling of the embodiment according to FIG FIG. 2 Approximately in the middle of a round or slot-shaped air inlet 3.2 and a round or slot-shaped air outlet 2.1 is provided in a housing. This housing is in turn formed of two shells 4.3 and 4.4, which enclose an interior 5.1. In the interior 5.1 a deflection 6.1 is attached, which is designed plate-shaped. This deflecting device 6.1 in turn separates the air inlet 3.2 from the air outlet 2.1 and is supported by the lateral flanges 13.1 and 13.3, which in FIG. 1 are recognizable.

Otherwise, it is merely provided that a mineral wool with fleece is used as deep absorber 12.1.

This overflow silencer has the advantage that a much higher volume flow can be promoted with low pressure drop. The volume flow is about twice as high as that in the device according to the FIGS. 1 and 2 ,
