Definitions
- the invention relates to an air outlet for a ventilation device and a drywall ceiling with an air outlet for a ventilation device.
- the invention relates to an air outlet which is integrated into an interior paneling (i.e. an interior drywall paneling).
- Ventilation devices generally comprise at least an air supply means, an air guiding device and an air outlet.
- the air guiding device is used to control the direction of air streams discharged from the ventilation device to achieve a favorable climate of the air flow.
- the ventilation should be carried out without perceptible air streams. When the air is cooled, it should be prevented that it drops vertically downwards from an air outlet located in the ceiling of the room and produces an unpleasantly strong stream of cool air.
- the outflow angle of the air flow is affected by several components of the ventilation device.
- the air is supplied to the outlet means in a stream feed direction and must thereafter usually be deflected in order to flow through an air outlet opening into tne room to be ventilated. This often occurs in a deflection and/or impact chamber.
- the outlet device can be provided with additional air guide elements.
- the air guide elements can be arranged to be movable to allow the user an individual adjustment of the direction and/or strength of the discharged air stream.
- the air passage is essentially the cover for the underlying ventilation device. So it visibly dominates the appearance of the ventilation device for the end user. However, this cover plate also affects the direction and flow behavior of the discharged air.- This can be used for the air guidance.
- the design can also be construed such that the cover plate, referred to hereinafter as air outlet, has minimal influence on the exiting air flow. For this reason, air outlets in the prior art often are lattice plates, thin perforated plates or thin slit plates in painted metal or sheet metal.
- the design of the visible air outlets is substantially determined by the function and does often is not appealing to the viewer.
- the ventilation devices with their air outlets form foreign objects in an otherwise homogeneous overall architectural appearance of a ceiling or a wall. There is therefore a need for air outlets that blend into the environment in which they are installed so that they visually interfere minimally with the overall architectural appearance.
- the functionality of the air passage should not be impaired, particularly when it is an air outlet.
- drywall panels made of gypsum plasterboards are used as drywall elements, these typically have a thickness of about 12.5 mm, while air passages known in the prior art are often only a few millimeters thick metal plates.
- Plasterboards have the advantage that they allow for other functionalities apart from the covering and dividing of spaces. With perforated gypsum plasterboards for example, acoustic noise reducing rooms can be built. There exist perforated gypsum boards with different hole or slot designs. There is a need for air passages that adapt these designs as much as possible, so that the overall architectural picture is not affected by it.
- the object of the invention is therefore to provide an air passage and an air outlet for ventilation devices, which allows easy installation and easy maintenance of ventilation systems.
- the air outlets are to be used particularly in drywall construction and can be visually fit into the interior design.
- the problem is solved by an air outlet with the features of claim 1 and a drywall ceiling with the features of claim 12.
- Advantageous embodiments are defined by their features normed in the dependent claims.
- An air outlet for a ventilation device comprises a plate with a plurality of air outlet openings, the air outlet being fixed in a manner so that when installed in a interior paneling it is foldable out of the interior paneling to make a space behind accessible.
- the ventilation device comprises an air supply means and an air guiding device.
- the construction of the air outlet which is foldable out of the interior paneling has the advantage that a drywall construction for the interior can be completed with an opening for a ventilation device by a professional (expert in building of drywalls) for drywall constructions. Subsequently, an installation of the ventilation device by a professional for ventilation is easily possible through the opening in the interior paneling.
- the professional for ventilation has not to initially form an appropriate opening (usually with little professionalism) in the drywall construction, but finds that work already done by the expert for drywall constructions.
- the opening may be releasably blinded by a customized or standardized air outlet produced by drywall manufacturer. This ensures a clean and straight design of the interior paneling made from one hand, wherein site requirements can be easily met. Additionally, at a later time maintenance of the ventilation device can be performed by release of the air outlet via simply folding it out from the interior paneling.
- An interior paneling according to this invention is understood to mean inter alia a drywall ceiling and/or a drywall construction wall, i.e. a separation drywall.
- the phrase air passage comprises air outlets and air inlets.
- air outlets air flows out of a ventilation device into a room while room air flows from the room into a ventilation device through air inlets.
- the invention is described below by reference to air outlets, because here, apart from the function to supply air to a room, other functions are necessary. With air inlets this is not the case to the same degree. Of course, the invention can therefore also be used as air inlet.
- the plate of the air outlet comprises a cover frame, which at least partially covers the air outlet openings of the plate.
- the cover frame is arranged so that it seals the air outlet openings disposed laterally from the ventilation device which are not covered by the ventilation device arranged at the plate.
- the air outlet can be made larger than necessary, e.g. greater than the ventilation device. This ensures sufficient space for the installation of the ventilation device, but also provides space for future maintenance.
- the cover frame serves to seal the air outlet openings which are not necessary for the ventilation against the back flow of air into the space between the ceiling or wall and the interior paneling. This is especially useful if an extremely flat outflow has to be realized.
- An extremely flat outflow angle is an angle between the ceiling or wall and the flow direction of the air stream of less than 25°, preferably less than 15°. The angle has to be sufficiently small such that the Coanda Effect is effected, meaning that the air flow is attracted by the ceiling and flows along the ceiling far into the room.
- the cover frame can preferably be designed in the manner of a closed frame so as to border the ventilation device on all sides. In this way, the air outlet openings provided for the ventilation device may be, for example, centrally arranged in the plate and are symmetrically enclosed by the closed frame like a visor.
- the cover frame is disposed on the side of the plate facing the ventilation device, the side of the plate visible to the viewer can be designed freely, without the visually disturbing cover frame. It is also possible to arrange the cover frame as a design element on the side of the plate visible to the viewer.
- cover frame is disposed on the side facing the ventilation device of the plate, it may be advantageous to at least provide the portions of the cover frame visible through the air ventilation openings of the plate in a dark color such as black, so that they do not visually differ from the other regions of the perforated plate and/or the interior paneling.
- the cover frame can advantageously be connected to the plate at the edges of the plate. If the plate is provided, for example, with a cover frame, an attachment to this frame can be easily realized without the visible surface of the plate being visually impaired.
- the frame has a chamfer towards the ventilation device.
- the chamfer can be a 45° chamfer.
- the chamfer is used to laterally align the ventilation device, the frame and the air outlet openings of the plate. Since the plate is fixed to the frame and is essentially non-slidable integrated into the interior paneling, an alignment must be done by moving the ventilation device. Since the ventilation device rests only on support beams of the interior paneling and is not fixed any further, such a displacement is possible without any effort.
- the outer edges of the ventilation device are seated on the plate of the air outlet. It is optically advantageous, if the edges of the ventilation device are seated on web portions of the plate without or at least with only with a minimum overlap with the air-outiet openings. For this purpose, an alignment of the ventilation device to the plate is necessary. If the outer edges of the ventilation device overlap with air-outlet openings visibility from below is not ruled out.
- the ventilation device comprises a chamfer at the contact edges which are in contact to the chamfer of the cover frame, an easy alignment of the ventilation device relative to the cover frame is possible via the mutually complementary sliding chamfer edges.
- the cover frame can be made from different materials, such as wood, aluminum, sheet steel, or plastic. Further, the cover frame may be of a solid material or be also a one piece profile/Preferably, a U-shaped sheet steel profile is used.
- the air outlet can be equipped with a mounting frame device.
- the mounting frame device is preferably in two parts and includes an outer mounting frame and an inner mounting frame. The outer mounting frame is secured to the interior paneling and the inner mounting frame is fixed to the plate of the air outlet. Preferably, both mounting frames respectively are formed circumferentially and include at least partly the edges of the plate or the opening in the interior paneling.
- the plate of the air outlet may have a lower thickness than the elements (drywall panels) of the interior (drywall) paneling.
- the thickness difference can be compensated by a spacer so that the bottom edge of the plate in a locked state is flush with the lower edge of the surrounding interior paneling.
- Such a flush installation of the visible surface of the interior paneling can nevertheless be achieved when different materials in different thicknesses are used.
- gypsum boards with a thickness of 12.5 mm for the interior paneling may be mentioned, which can be combined with a 1.5 mm thick plate to optimize the air outlet, without a ledge being created on the visible side or complicated assembly adjustments must be made.
- the thickness of the plate of the air outlet can also be adjusted via the thickness of the cover frame to the thickness of the interior paneling, as the cover frame is preferably secured to the inner mounting frame of the mounting device.
- the thickness of the plate of the air outlet is preferably less than 3 mm, particularly preferably less than 2 mm and in particular less than or equal to 1.5 mm. A small thickness of the plate has only a minimal effect on the air guidance. Depending on the material used for the plate and the dimensions of the plate, different thicknesses of the plate are necessary for a sufficient stability.
- the plate should be made as thin as possible.
- hinges or hinge joint components can be arranged on the plate of the air outlet.
- opposite small bolts can be provided that can be rotatably supported in pans in the interior paneling so that the plate can be rotated or pivoted about an axis.
- the plate advantageously comprises at least parts of a releasable locking device by which it can be detachably fixed to the interior paneling.
- a locking means which is released by pressure on the plate (i.e. particular portions of the plate) of the air outlet and which is based for example on a spring system.
- Such locking systems based on springs are especially preferred because they do not optically impair the visible side of the interior paneling including the air outlet.
- other locking systems can also be used, for example electronically controlled devices.
- the plate can have the same design as the interior paneling that is visible to a viewer so that the plate is visually indistinguishable from the surrounding interior paneling and seamlessly fits into this surrounding with respect to the designs and also the materials preferably used.
- This can for example be achieved by covering the visible side with gypsum plasterboard cardboard or with a lining, analogous to the surface, for example of gypsum plasterboards.
- the plasterboard liner or the lining can then be further treated in the same manner as the elements of the interior panel, for example, as the gypsum plasterboards. They can, for example, be coated with a primer and with an interior paint, preferably by roller application.
- the invention also relates to a drywall ceiling comprising a supporting structure of a plurality of metal profiles, an interior paneling mounted on the metal profiles, and at least one ventilation device comprising at least one air supply, an air guiding device and an air outlet.
- the air outlet comprises a plate with air outlet openings.
- the air outlet is mounted such that, in the installed state in an interior paneling, it is foldable out, of the interior paneling to make accessible a space behind.
- the interior paneling is made of gypsum plasterboards, especially of perforated gypsum plasterboards, so-called acoustic panels.
- Perforated gypsum plasterboards are widely used as building material for sound absorption and are particularly interesting because they already have a perforation pattern.
- the perforation pattern of the plate of the air outlet can be adapted to the perforation pattern in the perforated gypsum panels, so that the pattern visually continues without perceptible interruption, i.e. with respect to size, spacing and/or material.
- the air outlet openings of the plate of the air outlet then have the same design as the perforation pattern of the perforated gypsum plaster panels and extend this pattern further. They can, for example, be round or square, and arranged in a regular or irregular pattern.
- the pattern continues without interruptions (except tor unavoidable structural interruptions) with the same distance between adjacent holes at the transition from the perforated gypsum plasterboard to the air outlet openings in the plate of the air outlet.
- the distance between adjacent holes in the plate and adjacent perforations in the perforated plasterboard and the plate is the same. In other words, this means that the distance of the center point of the last opening in front of the edge rim to the edge rim of the plate is half as large as the distance between the center points of adjacent openings of the perforation pattern. If the perforations of the gypsum plasterboard and the openings of the plate are arranged side by side/ a uniform spacing results.

- the perforation 21 of the perforated gypsum plasterboard 2 with the black fleece is visible (black squares).
- the air outlet 3 does not optically differ from the perforated gypsum plasterboard 2 into which it is fitted. Simply due to their construction the abutting edges ot the pertorations in the perforated gypsum plasterboard 2 and the air outlet opening 3 of the plate are to be recognized.
- the plate 12 with the openings was covered (glued) on the visible side with a plasterboard liner, comprising corresponding openings to the openings in the plate 12.
- the plasterboard liner of the plate 12 was then primed and painted with, the same paint as the surrounding perforated gypsum plasterboard.
- the surfaces of the visible sides of the perforated gypsum plasterboard 2 and the plate with openings 12 are of the same material (gypsum plasterboard liner), which was further treated in the same manner (primer, paint).
- the pattern of the perforated gypsum plasterboard 2 and of the plate with openings 2 is identical in shape, size and spacing. The pattern is continuous as well as consistent. The designs of the perforated gypsum plasterboard and of the air outlet do not differ in any way.

- the cover frame 14 is fixed to the inner mounting frame 20 of the mounting frame device 18, 20 and laterally seals the air outlet openings of the air outlet.
- the peripheral inner edge of the cover frame 14 pointing to the diffuser has a 45° chamfer.
- the diffuser 8 has on its lower edge a peripheral chamfered portion lb wnicn is formed in this embodiment by an angle plate mounted at the lower edge of the diffuser 8. Via the mating 45° chamfers of the cover frame 14 and the diffuser 8, the diffuser 8 can be aligned on the support profiles 42 matching the air outlet 3 by simply moving the beams 6.
- FIG. 4 the same drywall ceiling 1 is shown in cross-section for better clarity again, but this time without a built-in ventilation device.
- the air outlet 3 is in the locked state.
- FIG. 5 shows an enlarged view of Fig. 4.
