Description

The invention relates to a ventilation component for installation in walls and in particular in Drywall, according to claim 1 and also a method for installing a Ventilation component according to claim 8.

The present invention is concerned with ventilation and air conditioning systems, and in particular the fresh air supply and the exhaust air discharge from rooms, with corresponding Rooms that are to be ventilated and ventilated, ventilation components according to the generic term of Claim 1 can be assigned.

Known ventilation components have the disadvantage that they are only integrated into the building can be, for example, in a so-called in suspended ceiling areas Can be integrated. Must have these ventilation components, as a rule the case in which the ceiling area of a building is installed in a wall massively into the adjoining room, a hallway or hallway. That is, well-known ventilation components cannot be integrated into a wall. It doesn't just happen to form thermal bridges but sound from the adjacent room can pass through the Housing of a ventilation component, usually a sheet metal housing, are transferred. Is too it is regularly complex, when laying water pipes, power lines and the like, which are usually carried out in corridors or corridors in the area of the ceiling will tolerate the disabilities caused by the above ventilation components arise.

Another problem arises from the fact that all the known ventilation components must have separate soundproofing elements, the sound coming from the ventilation system could spread, dampen or even completely absorb. Ultimately, since the well-known Ventilation components do not fit sufficiently into a wall due to their dimensions can be integrated, they also protrude into the room to be ventilated and they protrude Areas are usually covered with separate decorative surfaces around the ventilation components to be able to tolerate optically. These decorative surfaces must then be used for assembly work and painting work are protected.

In the prior art, it is also problematic that the housing of ventilation components are designed so that they have a greater horizontal extension in the installed position, a tangential flow from the connection of the ventilation or air conditioning system to allow to the room side. This makes it particularly well known Constructions made impossible in reality, these in vertical walls Integrate building, these vertical walls have usual thicknesses, such as 100 mm or 150 mm, as is particularly common with drywall.

It is the object according to the present invention, a ventilation component and a method to install a ventilation component that create the foregoing To remedy disadvantages in the prior art at least partially as far as possible. In particular, a ventilation component is to be created that allows installation in a Wall and in particular a drywall allows. A corresponding procedure should can also be proposed. According to the invention, their advantages are based on Ventilation component in which the housing has a larger vertical or to the installation wall when installed has greater parallel than horizontal extension, with the supply air connection and / or the exhaust air connection connects to the vertical side or the side extending parallel to the wall, the room ventilation area is vertically or laterally offset on the opposite inside of the housing is arranged. The housing has according to the invention a larger vertical or parallel extension to the wall than a horizontal extension in the installed position Extension, whereby the supply air connection and / or the exhaust air connection to the vertical or connects parallel to the wall, the room ventilation area and / or the room ventilation area is vertically or laterally offset on the opposite inside of the housing is arranged.

This folding of the housing of the ventilation component according to the invention makes it surprising possible to achieve a minimum installation depth, so that the invention Ventilation component also in thinner drywall with a thickness of about 100 mm or 150 mm can be integrated without the ventilation being larger or deeper Rooms is at risk. Below deeper rooms are rooms with a depth of up to 7 m and understood more.

That means that a very essential aspect according to the invention is the folding of the propagation path the air flow through the ventilation component to see what is surprisingly without any restrictions on the ventilation performance can be.

Can advantageously in the room ventilation and / or ventilation area of the ventilation component after its installation, a room ventilation device and / or a room ventilation device preferably be installed reversibly. That is, after the invention Ventilation component has been integrated into a wall, is the room ventilation and / or ventilation area accessible in such a way that a room ventilation device and / or a room ventilation device can / can be installed. Such as an outlet nozzle strip designated room ventilation device or room ventilation device is approximately from the German patent DE 195 29 311 C1 known, which goes back to the applicant. Such Outlet nozzle strip or a comparable room ventilation device / room ventilation device can be adapted to the ventilation component according to the present invention are used here.

A ventilation component according to the invention can advantageously be designed for each Room ventilation and room ventilation may be provided. On the other hand, it is also beneficial possible to form the housing section in two parts, so that in a single housing both room ventilation and room ventilation can be provided.

The ventilation device and / or the ventilation device, for example in the form of the outlet nozzle strip according to DE 195 29 311 C1, can advantageously in a mounting frame preferably used reversibly. The mounting frame can also be at least partially the function of the ventilation outlet or the ventilation inlet from or in meet the housing.

The complete installation of the ventilation component according to the invention makes it possible to Reduce thermal bridges to a minimum, otherwise through the whole Housing that according to the invention now in a wall and. especially in a drywall can be fully admitted, would arise massively. Also a transfer of vibration or sound is made possible by the advantageous according to the invention Integration of the ventilation component in a thin wall even reduced to a minimum.

The transmission of sound, in particular through the ventilation or air conditioning system can further reduce at least one side or wall of the housing of the ventilation component according to the invention with a sound absorbing structure be provided. This sound absorbing structure can be used as a damping plate and / or Sound reflecting structure can be formed.

To the room ventilation device and / or the room ventilation device in an advantageous An easily reversible connecting means can be provided in a manner that is reversible his. Snap connections have proven to be particularly advantageous here, since they are hardly require a tool and yet are resistant to vibration and a fixed one can provide mechanical connection.

Advantageously, the ventilation component according to the invention is also provided with a throttle element, provided, for example, in the form of a throttle valve or the like, around the For example, individually adjust the air flow to the air supply to a room to be ventilated to be able to. If desired, the air discharge can also be regulated, for example by a small one To be able to set excess pressure in the room, to influence a draft, or the like more.

Because the ventilation device is reversible and easy from the outside Are provided accessible, it is also possible that the housing as well as the ventilation device and to clean the ventilation device without extensive assembly measures are required, as is the case in the prior art.

The proposed method according to the invention can be used for the installation of any Process built-in ventilation components are used and is particularly suitable for a ventilation component which is designed according to the present invention.

According to the invention, a ventilation component is inserted into a drywall. On A first wall plate facing away from the room is attached to a supporting structure. This wall plate is provided with through-openings for a supply air connection and / or to arrange an exhaust air connection for the ventilation component, via which the ventilation component can be connected to a ventilation or air conditioning system.

The ventilation component is thus on the first wall plate facing away from the room, which is double-layered can be attached, which defines a second facing the room Wall plate is possible without components of the housing of the built-in ventilation component look out from the wall level. In the wall plate facing the room If one or more openings are incorporated in order to ventilate the one to be vented Connect space to the housing, which is completely housed in the drywall. Advantageously extends into these openings provided in the second wall plate a frame provided in or on the housing of the ventilation component, in which a room ventilation device and / or a room ventilation device, such as in the Shape of the outlet nozzle strip according to DE 195 29 311 C1, preferably by means of reversible Assembly tools can be used.

The room ventilation and / or ventilation devices are advantageously only after Completion of the drywall used reversibly.

shows a detail of an embodiment that uses a different room ventilation device or room ventilation device, in a vertical sectional view.

In the illustrations, identical or at least functionally identical components are identical Reference numerals named, and a multiple discussion of corresponding parts is unnecessary yourself with it.

In Figure 1 is a ventilation element with side walls 12, 14, an upper end wall 15 and a lower end wall 13. The housing with the walls 12, 13, 14, 15 includes both a room for the supply air and a room for the exhaust air. Accordingly a supply air opening 16 is provided and there is an exhaust air opening 18 in one separated section of the housing of this ventilation component arranged. The supply air opening 16 has a connection via which it is connected to a ventilation or air conditioning system (not shown) is connected so that fresh air or conditioned fresh air is supplied can be. Conversely, the exhaust air opening 18 is also connected to the Ventilation or air conditioning system connected to the used air from the ventilating or air-conditioned room in which the ventilation component according to FIG. 1 is installed to remove.

The ventilation component, in particular for installation in drywall, folds the air flow and thus the housing is 16 in its main direction of extension relative to the supply air or the exhaust air 18 extends at a substantially right angle. Also to be found Venting and venting devices 22 facing venting space can essentially at a right angle to a vertical direction of extent of the housing be arranged. The essentially same benefits can also be achieved if the supply air connection 16 and the inlet 21, 22 assigned to this supply air connection 16 are not are vertically offset from each other, but horizontally offset from each other are, d. that is, the room ventilation device 21, 22 facing the room is horizontal in the supply air connection 16 offset.

As can also be seen in FIG. 2, the supply air 16 is on the rear side wall 41 of the housing 5 arranged. The same applies to the exhaust air connection 18. The connections 16, 18 are arranged in the middle, at the upper end of the housing 5, but they can can also be arranged laterally offset. Ultimately, the folding of the air flow is essential between ports 16, 18 on page 41 and the outlet (s) 22 on page 42. The ventilation component shown can also be used, for example, with the connections 16, 18 below and the inlets / outlets 22, d. H. the room ventilation systems 22, can be installed above.

A partition 20 is between the supply air section and the exhaust air section of the housing, which is generally designated with the reference number 5, arranged.

At the lower end of the housing 5 there are room ventilation devices in a slide-in or holding frame 21 as well as a room ventilation device 22 added. these can for example, analogous to the outlet nozzle strip according to DE 195 29 311 C1 to blow fresh air into the room to be ventilated or to extract air from this room to dispose.

The air flow supplied via the supply air opening 16 is fed into the supply air section of the housing 5 redirected or folded twice opposite by about 90 ° and then over the Vents and the guide portions of the room ventilation device 22 in the room introduced. Room depths of 7 m and more can be well ventilated here. Also in the area the partition 20 is the one-piece room ventilation device separated, so that if possible a short circuit between the supply air section and the Drain section of the housing 5 can be prevented.

In Figure 1 (and in Figures 2 and 3) an embodiment is shown in which in a and the same housing 5 integrates both the supply air section and the exhaust air section are, but this is not necessary. It is easily possible to have separate housing sections to train for the supply air and for the exhaust air according to the invention.

FIG. 2 shows that the room ventilation and ventilation device 22 is above Fastening sections 28 are held reversibly in the frame 21, the frame 21 also takes on the task of folding the air flow into the frame 21 and thus in about 90 ° to transfer the room ventilation and ventilation device 22. In the present case the mounting device 28 is designed as a snap connection, but also latching connections or screw connections are possible without this imposing any significant restrictions would be feared in terms of ease of use.

The ventilation component according to FIGS. 1 to 3 can, for example, have a mounting bracket 24 on the ceiling of a building within a drywall (see Figures 3, 4) be attached. The possibilities of fastening are varied and the simplest Case can also be achieved with construction foam, glue or the like. In Figure 2, the separation in the room ventilation 22 is with the reference numeral 26 identified. However, as noted, this separation is not essential required because only small air masses directly from the supply air section into the exhaust air section can guess.

A dashed line 32 shows a sound absorption section, which also is known as a telephony silencer. Telephony silencers of this type are conventionally required may be provided separately while also based on the present invention the folding of the space of the housing 5 relative to the supply air 16 and the exhaust air 18 Possibility results, this telephony silencer opposite the supply air opening or opposite the exhaust air opening 18 and the supply air opening 16 so that an effective Sound absorption can be made possible without further measures.

FIG. 3 shows the ventilation component according to the present invention according to FIGS. 1 and 2 shown in its installed position in a drywall. The ventilation component According to the invention is arranged near a ceiling 8 and is completely between the wall 9 facing away from the room, d. H. the corridor wall, and the one facing the room to be ventilated Wall 10, d. H. the office wall. Only the nozzle of the exhaust air opening 18 according to section A-A of Figure 1 looks in the hallway near the ceiling 8 to the connection a vent pipe (not shown), such as a corrugated pipe, to enable.

As can be seen, the vertically extending free space 30 between the outer wall, i. H. the corridor wall 9, and the inner wall, d. H. the office wall 10, through the housing with the bottom wall 13 and the upper wall 15 substantially in the vertical direction and completely filled in in the direction of the wall depth. The sound attenuation or telephony noise attenuation is arranged opposite the exhaust opening 18 so that sound is transmitted is absorbed here and extends along the housing in front of the room to be ventilated assigned exhaust opening 21, 22 runs dead and through multiple reflections and absorption is absorbed by the vertically extending telephony muffler plate 32.

As can be seen, the frame 21 in which the room ventilation device or Room ventilation device 22 is reversibly mounted, fully integrated in the office wall 10 be, since additional connection elements are not required. As another connection element here is the. to designate the room to be ventilated.

In contrast, of course, for a connection to the ventilation system or air conditioning system On the side of the hallway, a nozzle should be provided. On the other hand, the expert can introduce other connection options here, such as a connection pipe with thread or bayonet lock, so that the nozzle of the exhaust opening 18 is only a short should have horizontal extension so that the nozzle does not extend beyond the level of the Wall 9 should extend. In this way, the ventilation component according to the invention be designed so that it could be fully integrated into the wall 9, 10.

While Figures 1 and 3 a relatively high and therefore more suitable for larger amounts of air Room ventilation and ventilation device 22 can show this for small rooms or rooms can also be made smaller with a lower air exchange volume, as shown in FIG. 4 is shown. There, the room ventilation and ventilation device 22 is only half the opening cross-section Mistake. However, this embodiment can not only for smaller rooms come into consideration, but also for rooms with greater depth, where higher air flow velocities must be achieved to fully ventilate the depth of the room or to vent.

The present invention enables the air conditioning system or the ventilation system to be folded assigned connections 16, 18 to the room ventilation assigned to the room and venting devices 22 are of surprisingly advantageous construction the inclusion of the ventilation component according to the invention even in thin walls, in particular Drywall, allows. This construction also allows the arrangement and thus the integration of a sound attenuation device that acts as a telephony sound attenuation in the State of the art is known. The reversible installation of the room ventilation system or the room ventilation device, d. H. such as an outlet nozzle strip according to DE 195 29 311 C1, enables subsequent cleaning of the ventilation component according to the invention or in the case of renovation, easy handling, because the facility 22 does not have to be covered, but can simply be removed. It is too possible to adjust the volume flow via throttle slide from the valve to be vented To allow space out. This can be done manually or using an electric motor a remote control, such as a control potentiometer, an infrared remote control or the like respectively. Automation is also possible, for example using a thermometer electronically read control value used for automatic control of a throttle valve can be.
