Description

  The present invention relates to an air outlet of a ventilator and a dry wall ceiling provided with the air outlet of the ventilator. In particular, the present invention relates to an air outlet that is incorporated in an interior panel (ie, an interior drywall panel).

  In the prior art, ventilation devices for ventilation and air conditioning of rooms are known. They are used for air conditioning or temperature regulation of the room, in other words for the supply of conditioned air, ie warmed, cooled, dried and / or humidified air.

  In general, the ventilation device includes at least an air supply unit, an air guide device, and an air discharge port. The air guide device is used to achieve a favorable environment of airflow by controlling the direction of the flow of air discharged from the ventilation device. Ventilation should be done in such a way that no air flow can be perceived. When the air is cooled, it should be prevented that the air flows vertically downward from the air outlet installed on the ceiling of the room, and an unpleasant strong flow of cold air is generated.

  In order to avoid this, in the case of a high air outlet, the air flow coming from the outside is distributed in the direction of the air outlet so that it flows along the ceiling in each direction of the room. The so-called Coanda effect is used. In order to achieve this at the ceiling outlet, a horizontal discharge of air from the ceiling outlet is essential.

  The air discharge angle is affected by several components of the ventilator. Air is supplied to the discharge means in the direction in which the flow is supplied, and then usually needs to be deflected in order to flow through the air discharge opening into the ventilated room. This often occurs in deflection and / or collision chambers.

  In order to allow precise and flexible control of the discharged air flow, the outlet device can be provided with an additional air guiding element. The air guide element may be movably arranged so that the user can individually adjust the direction and / or strength of the air flow discharged.

  Another element of the ventilation device is an air passage. The air passage is essentially a cover below the ventilator. Thus, for the end user, the cover clearly governs the appearance of the ventilator. However, this cover plate also affects the direction of the discharged air and the airflow behavior. This can be used for air guidance. On the other hand, a cover plate, which will be described later as an air discharge port, can further adopt a design that has a minimal influence on the outgoing airflow. For this reason, prior art air outlets are often lattice plates, thin perforated plates or thin slit plates made of painted or sheet metal.

  In effect, the design of the visible air outlet is determined by the function and is often unattractive to the viewer. Furthermore, ventilators with air outlets otherwise form foreign objects in the architectural appearance throughout the homogeneous ceiling or wall. Accordingly, there is a need for an air outlet that is integrated and integrated into the environment with minimal visual disturbance to the overall architectural appearance. However, the functionality of the air passage should not be impaired, especially when the air passage is an air outlet.

  This problem is particularly apparent in ventilators that are inserted into suspended interior drywall panels. However, the construction of a drywall panel (ie, gypsum board) that is attached to a support profile provides space between the wall or bare ceiling and the drywall panel. This space can be used to accommodate invisible parts of the ventilator. However, the relatively large thickness of the drywall panel means that the air outlet made of a thin plate does not finish on the same plane as the outer edge of the drywall panel.

  When drywall panels made of gypsum board are used as drywall elements, the gypsum board typically has a thickness of about 12.5 mm, while the air passages known in the prior art are Often, metal plates with a thickness of a few millimeters.

  Gypsum board has the advantage of allowing other functions apart from covering and partitioning the space. For example, a perforated gypsum board can be used to build a room that reduces acoustic noise. There are perforated gypsum boards with various hole or groove designs. There is a need for an air passage that can adapt as much as possible to these designs so that the overall architectural aspects are not affected by the air passage.

  In general, it is possible to use perforated gypsum board holes or perforations as air passages. In such a case, the air outlet will not differ from the appearance of the rest of the ceiling. However, this solution provides insufficient comfort to the consumer because the relatively large thickness of the gypsum board prevents outflow of air at a horizontal angle.

  There is a further disadvantage of combining the ventilation system with a drywall construction. At present, the ventilation system is not part of the drywall construction system. This means that the ventilator is installed after completion of the drywall construction, often with damage to the assembled drywall construction. The independent planning and the different focus of interest of the manufacturer, on the one hand for the construction of drywalls on the other hand, and the ventilation system on the other hand, can almost meet the requirements of the actual construction site where the ceiling suspension height is low. Absent.

  Conventional ceiling passages are built into the drywall ceiling. The manufacturers of drywall construction and ventilation systems do not understand each other, so the previously known design solutions are not very attractive. Generally, the discharge opening is made of a painted sheet metal. This means that no matter how good all the quality, the passage is always visually visible and interferes with the design of the drywall ceiling.

  Accordingly, an object of the present invention is to provide an air passage and an air discharge port of a ventilating device that allow easy incorporation and easy repair of a ventilation system. Air outlets are used in particular for drywall construction and can visually match the interior design.

  The object is solved by an air outlet comprising the features of claim 1 and a drywall ceiling comprising the features of claim 12. Advantageous forms are defined by the features defined in the independent claims.

  An air discharge port of a ventilating apparatus according to the present invention includes a plate having a plurality of air discharge openings, and the air discharge port is configured to provide a space that can be accessed rearward when incorporated in an interior panel. It is fixed in such a way that it can be folded from the panel. In addition to at least one air outlet, the ventilation device includes an air supply means and an air guide device.

  The construction of the air outlet that can be folded from the interior panel means that the drywall construction for the interior can be provided with an opening for the ventilation device by a drywall construction craftsman (expert who makes the drywall) Has advantages. Thereafter, the ventilation device can be easily incorporated by the ventilation craftsman through the opening of the interior panel. A ventilated craftsman realizes that dry wall construction does not have to first be made with a suitable opening (usually an opening by an amateur job) and has already been done by a dry wall construction specialist. After installation of the ventilator, the opening may be made detachable and visible by a customized or standardized air outlet produced by a drywall manufacturer. This ensures a clean and straight design of the easily produced interior panel and can easily meet the field requirements.

  In addition, the subsequent repair of the ventilation device can be performed by detaching the air outlet by simply opening the air outlet from the interior panel.

  The interior panel according to the invention is understood in particular in the sense of drywall ceilings and / or drywall construction wall materials, ie dry partition walls. The phrase air passage includes an air outlet and an air inlet. Through the air outlet, air exits the ventilator and flows into the room, while room air flows from the room to the ventilator through the air inlet. In the case of the air discharge port, another function different from the function of supplying air to the room is necessary. Therefore, the present invention will be described below with reference to the air discharge port. This is not the case with the air inlet. Of course, the present invention can therefore also be used as an air inlet.

  As a particularly preferable aspect, the plate of the air discharge port includes a cover frame, and the cover frame at least partially covers the air discharge port of the plate. Particularly preferably, the cover frame is arranged so as to seal the plurality of air discharge openings arranged on the side of the ventilation device which is not covered by the ventilation device arranged on the plate. According to this, the air discharge port can be made larger than required so as to be larger than the ventilation device, for example. As a result, a sufficient space for assembling the ventilation device is secured, and a space for future repairs is also provided.

  The cover frame is used to seal air flow back to the space between the ceiling or wall and the interior panel at the plurality of air discharge openings that are not required for ventilation. This is particularly useful when it is necessary to achieve very horizontal discharge. A very horizontal discharge angle is an angle between the ceiling or wall and the air flow direction of less than 25 °, preferably less than 15 °. The angle needs to be small enough to exert the Coanda effect, i.e. the airflow is attracted by the ceiling and flows along the ceiling as far as the room.

  The cover frame may preferably be designed in the form of a close frame so as to face all sides of the ventilation device. According to this, the air discharge port provided in the ventilation device may be disposed at the center of the plate, for example, and symmetrically surrounded by a close frame such as a visor.

  When the cover frame is arranged on the surface of the plate facing the ventilation device, the surface of the plate that can be visually recognized by a viewer can be freely designed without being visually disturbed by the cover frame. The cover frame may be arranged as a design element on the surface of the plate that is visible to a viewer.

  When the cover frame is disposed on a surface of the plate facing the ventilation device, at least a portion of the cover frame that is visible through the air ventilation opening in the plate is a dark color such as black. There may be the advantage that the air vent openings are not visually distinguishable from other areas of the perforated plate and / or the interior panel.

  The cover frame may advantageously be coupled to the plate at the edge of the plate. For example, if the plate is provided with the cover frame, attachment of the frame can be easily achieved without visually damaging the visible surface of the plate.

  As a particularly preferable aspect of the present invention, the frame has a chamfered portion with respect to the ventilation device. The chamfer may be a 45 ° chamfer. The chamfered portion is used to laterally align the plurality of air discharge openings of the ventilation device, the frame, and the plate. Since the plate is fixed to the frame and incorporated in the interior panel so that it cannot essentially slide, alignment must be done by moving the ventilator. Since the ventilation device is supported only by the support beam of the interior panel and is not fixed any more, such installation can be performed without labor.

  The outer edge of the ventilator is installed on the plate at the air outlet. It is visually advantageous if the edge of the ventilator is mounted on the plate mesh so that there is no or at least minimal overlap with the plurality of air discharge openings. For this reason, alignment of the ventilation device to the plate is essential. When the outer edge of the ventilator overlaps with a plurality of air discharge openings, visibility from below is not excluded.

  Here, in the case where the ventilation device includes a chamfered portion at a contact edge that contacts the chamfered portion of the cover frame, the chamfered portion end where the easy alignment of the ventilation device with respect to the cover frame complements each other This is possible by sliding the edges.

  The cover frame can be made from a variety of materials such as wood, aluminum, sheet steel or plastic. Further, the cover frame may be a solid material or an integral shape. Preferably, a U-shaped sheet-like steel profile is used.

  In order to allow easy, stable and durable attachment of the air outlet in the interior panel, the air outlet may be equipped with an attachment frame device. The mounting frame device preferably comprises two parts and includes an outer mounting frame and an inner mounting frame. The outer mounting frame is fixed to an interior panel, and the inner mounting frame is installed on the plate of the air discharge port. Preferably, both mounting frames are each formed in a circumferential shape and at least partially include an edge of the plate or an opening of the interior panel.

  The plate of the air outlet may have a smaller thickness than an element (dry wall panel) of an interior (dry wall) panel. The difference in thickness can be adjusted by the spacer so that the bottom edge of the plate in the fixed state is flush with the bottom edge of the surrounding interior panel. In this way, a uniform mounting is possible on a common or different but similar support element.

  Such coplanar incorporation of the visible surface in the interior panel can be achieved even when different materials with different thicknesses are used. As an example, a gypsum board having a thickness of 12.5 mm as the interior panel will be described. The gypsum board does not need to have a bulge on a visible surface or need to be complicatedly adjusted. It can be coupled to a 1.5 mm thick plate for optimizing the air outlet.

  In addition, the thickness of the plate of the air discharge port depends on the ratio of the thickness of the cover frame and the thickness of the interior panel so that the cover frame is preferably fixed to the inner mounting frame of the mounting device. Can be adjusted.

  The thickness of the plate of the air outlet is preferably less than 3 mm, more preferably less than 2 mm, and even more preferably less than 1.5 mm or equal to 1.5 mm. The small thickness of the plate has a minimal effect on the air guide. Depending on the material used for the plate and the dimensions of the plate, different thicknesses of the plate are required for sufficient stability. The plate should be made as thin as possible.

  Use of a hinge or hinge system is provided to fold the air outlet from the interior panel. Preferably, a hinge or hinged component may be disposed on the plate of the air outlet. For example, small small bolts that can be rotatably supported on the top panel of the interior panel can be applied so that the plate can rotate or pivot about an axis.

  In addition, advantageously, the plate may comprise at least a detachable locking device and be detachably fixed to the interior panel. Particularly preferred is a locking means, which is detached by pressing on the plate of the air outlet (ie a specific part of the plate), for example a locking means based on a spring system. . Such a spring-based locking system is particularly preferred because it does not visually impair the visible surface of the interior panel including the air outlet. In principle, other locking systems can also be used, for example electronically controlled devices.

  In order to achieve a uniform or uniform visual appearance of the interior panel, the plate is visually indistinguishable from the surrounding interior panel and seamlessly around this perimeter regarding the design and materials used preferably To harmonize, the plate may have the same design as the interior panel that is visible to the viewer. This can be achieved, for example, by covering the visible surface with a gypsum board base paper or with a backing similar to the surface of the gypsum board, for example. The liner or backing of the gypsum board can be further processed in the same manner as the elements of the interior panel, such as gypsum board. For example, they can be painted with a primer and painted with an interior paint, preferably by use of a roller.

  In addition to the air outlet of the ventilator, the present invention relates to a drywall ceiling, the drywall ceiling comprising a plurality of metal profile support structures, an interior panel attached to the metal profile, and at least one ventilator. The ventilation device includes at least one air supply unit, an air guide device, and an air discharge port. The air discharge port includes a plate having a plurality of air discharge openings. The air discharge port is attached so as to be able to be opened from the interior panel in order to facilitate access to the rear space in a state where the air discharge port is incorporated in the interior panel.

  More preferably, the interior panel is made of a gypsum board, in particular, a perforated gypsum board called a soundproof panel. Perforated gypsum board is widely used as a building material for absorbing sound, and of particular interest is that perforated gypsum board already has a perforated pattern. The perforation pattern of the plate at the air outlet can be adapted to the perforation pattern on the perforated gypsum board so that the pattern is not visually perceptible, i.e. without perceptual interference with respect to size, space and / or material. It is continuous. The plurality of air outlet openings of the plate at the air outlet have the same design as the perforated pattern of the perforated gypsum panel, further expanding this pattern. They are, for example, circular or square and can be arranged in a regular or irregular pattern.

  This is because the pattern has the same distance between adjacent holes at the transition from the perforated gypsum board to the plurality of air discharge openings in the plate of the air discharge openings, and interference (inevitable structure) Means continuous (without interference). The distances between adjacent holes in the plate and adjacent perforations in the perforated gypsum board and the plate are the same. In other words, this means that the distance between the center of the last opening in front of the edge in the plate and the edge is the same distance as half the distance between the centers of adjacent openings in the drilling pattern. means. When the perforation of the gypsum board and the opening of the plate are arranged in parallel, the intervals are uniform.

  The invention will now be described in more detail by way of example with reference to the drawings. Throughout the drawings, like reference numbers indicate like features.

Top view of drywall ceiling with ventilator Bottom view of drywall ceiling with ventilator Cross section of drywall ceiling with ventilation device Cross section of a drywall ceiling without air vents with an air outlet 4 is an enlarged cross-sectional view of FIG.

  FIG. 1 shows a construction in an embodiment of a drywall ceiling 1 according to the invention with a ventilator fitted in top view when viewed from the ceiling towards the floor. The drywall ceiling 1 is installed in a suspended ceiling style. A plurality of base profiles 41 are attached to the exposed ceiling. The carrier profile 42 is attached to the base profile 41 so as to be at right angles to these base profiles 41, and sequentially constructs a framework to which the building panel 2, here perforated gypsum board 2, is attached. The perforated gypsum board has an upper surface covered with a backing, and in this case, a black fleece is laid on the upper surface. For this reason, in the top view of FIG. 1, the hole 21 of the perforated gypsum board 2 cannot be visually recognized.

  The perforated gypsum board 2 has an opening (not shown) into which the ventilation device 8 is inserted. In this example, the ventilation device 8 includes an air diffuser. The air diffuser 8 comprises a beam 6 and is thereby supported on two support profiles 42. The air diffuser 8 can move freely over the support profile 42 and is not fixed any further.

  The opening of the perforated gypsum board 2 is sealed by the air discharge port 3. In FIG. 1, since the air diffuser 8 covers the central part of the air outlet 3, only the outer edge of the air outlet 3 can be seen. The air discharge port 3 has a plate having an air opening. In this case, the plate is a perforated plate 12 (not shown) having a size of 600 × 600 mm and a thickness of 1.5 mm. The inner mounting frame 20 is circumferentially surrounded at the edge thereof. The internal mounting frame is an aluminum profile.

  A hinge 22 is attached to the internal mounting frame 20 so that the air discharge port 3 can be folded open from the drywall ceiling around a common axis. At the end edge, a spring mechanism 24 is disposed so as to face the hinge 22. The spring mechanism 24 fixes the air discharge port 3 at the opening of the perforated gypsum board 2. The fixing structure can be detached by pushing from below the air outlet 3. In order to prevent abrupt lowering of the air outlet 3 from the opening of the perforated gypsum board 2, a catch hook 28 is further provided on the internal mounting frame 20. The catch hook 28 holds the air discharge port 3 in a half-open position after the air discharge port 3 is detached.

  2 shows the same part of the drywall ceiling 1 shown in FIG. 1, but here it is a bottom view, ie a bottom view from the viewpoint of an observer looking at the ceiling from the floor. In this figure, the perforations 21 of the perforated gypsum board 2 with black fleece are visible (black squares). It will be further understood that in the perforated plate 12, the air outlet 3 harmonizes with the perforated gypsum board 2 and is not visually different from the perforated gypsum board 2. According to their simple construction, it can be seen that the edge of the perforation in the perforated gypsum board 2 and the air discharge opening 3 of the plate are adjacent.

  In order to achieve visual unification between the perforated gypsum board 2 and the holes in the plate 12, the plate 12 with the openings is covered (adhered) with a gypsum board liner visible surface, and the openings in the plate 12. With an opening corresponding to. The gypsum board liner of the plate 12 is then primed and painted with the same paint as the surrounding perforated gypsum board.

  Thus, the surface of the visible surface of the plate comprising the perforated gypsum board 2 and the opening 12 is the same material (liner of the perforated gypsum board) and is treated in the same way (priming, painting). The pattern of the plate with the perforated gypsum board 2 and the openings 2 is identical in shape, size and spacing. The pattern is continuous in harmony. The design of perforated gypsum board and air outlet is no different.

  FIG. 3 shows a cross-sectional view of the drywall ceiling 1. In this depiction, the arrangement of the ventilator 8 with the air supply 10 on the plate with the opening 13 in the air outlet 3 is shown. A cover frame 14 is disposed on the side opposite to the viewer's side of the dry ceiling so as to surround the plurality of air discharge openings 13 of the plate 12. The frame is painted black on the underside (not shown) towards the viewer so that when viewed through the plate opening 12, it is not visually distinguishable from the black fleece used for perforated gypsum board. . The cover frame 14 is made of a sheet-like steel profile, and has an outer dimension of 598 × 598, a frame width of 45 mm, and a thickness of 12 mm.

  The cover frame 14 is fixed to the inner mounting frame 20 of the mounting frame devices 18 and 20 and seals a plurality of air discharge openings of the air discharge ports laterally. The inner peripheral edge of the cover frame 14 facing the diffuser has a 45 ° chamfer. In order to fix the shape there, the air diffuser 8 has a peripheral chamfered portion 16 at the lower end edge, and the peripheral chamfered portion 16 is attached to the lower end edge of the air diffuser 8 in this embodiment. It is formed by an angle plate. By matching the 45 ° chamfers of the cover frame 14 and the air diffuser 8, the air diffuser 8 is simply moved on the support member 42 so as to coincide with the air outlet 3 by moving the beam 6. Can be aligned.

  In FIG. 4, for the sake of further clarity, the same drywall ceiling 1 is shown in a sectional view, but here the aeration device fitted is not shown. The air discharge port 3 is in a fixed state.

  FIG. 5 shows an enlarged view of FIG. In this enlargement, the arrangement of the mounting frame device comprising the outer mounting frame 18 and the inner mounting frame 20 is clearly visible. Both the outer mounting frame 18 and the inner mounting frame 20 are made of an aluminum shape that is continuous in a circumferential shape. The cover frame 14 is fixed to the plate having the opening 12 by the inner frame 20. The cover frame 14 compensates for the difference in thickness between the perforated gypsum board 2 and the plate with the openings 12 so that the “perforated gypsum board” 2 and “air outlet” 3 as elements are of equal thickness.

  The distance a between adjacent perforations 21 in the perforated gypsum board is the same as the distance b between the openings 21 at the transition from the perforated gypsum board 2 to the plurality of air discharge openings 13 of the perforated plate 12. The broken line indicates the position of the cylindrical axis of the hole in the perforated gypsum board or the hole in the plurality of air discharge openings 13 of the perforated plate.
