    TECHNICAL FIELD The present invention relates to a ventilation device, for example for use in ventilation ducts for exhaust air in a boiler.
    Background of the invention The background of the invention is based on the problems that occur in apartment buildings when cooking in a kitchen in one of the law units in the house. Matos and water supply are normally led up through the ventilation system and out through an outlet port. Such a ventilation system is in many cases insufficient to ventilate a kitchen sufficiently and many unit holders who are connected to such a ventilation system wish to install a forced flat system for their own kitchen. A ventilation system with draft, carbon filter flap or forcing cap is in many cases insufficient to ventilate a storage unit sufficiently during cooking. , washrooms and toilets and many unit holders therefore want to install a forced flattening system for their own kitchen. The problem becomes in such a case that the forcing coke flake will create an air flow which pushes air back through the ventilation system and into the own or the storage units which have a lower pressure and flow than the forcing flake.
    The risk is also great that the cooking air is also pushed in a neighboring unit further in the opposite direction to a tank normal flow out of the boiler and into adjacent rooms.
    A central flue which administers the supply of ventilation air to the true storage unit connected to the system also suffers from the same problem if a storage unit installs a forced flattening system for its own kitchen and this creates a higher pressure than the pressure in the central system. In view of this converted air flow, in other multi-family houses, other coke flats other than carbon filter alternatives are normally not allowed, which only circulate food through the carbon filter without completely purifying the air. With a rapidly decreasing degree of purification, the carbon filter surface whips around the soot in the kitchen, which is partly spread further out in the unit towards other exhaust air appliances which suck at least 15 Ws in bathrooms, but often 25-30 Ws in several water spaces compared to the kitchen's basic flow of 101 / s. Ventilation of matos with carbon filter flats in the kitchen is therefore insufficient for good coke ventilation. Modern coke flakes can give the air flow of about 100-5001 / s (liters / second) and these coke flakes cause the said problem with the return flow.
    Object of the invention The object of the present invention is to provide a ventilation device which solves the above-mentioned problems and allows unit holders in multi-family houses to install forced coke ventilation.
    The object is further that a device according to the invention should be able to be installed in existing ventilation ducts.
    The object is also that a device according to the invention should be easy to install and easy to clean.
    In addition, the purpose is that the device should be easy to maintain and that parts can be easily replaced.
    SUMMARY OF THE INVENTION By the present invention as set forth in the independent claims, the above objects are met whereby said disadvantages have been eliminated. Suitable embodiments of the invention are set forth in the dependent claims.
    The invention relates to a ventilation device which comprises a flat support member with an air-permeable surface. The support member is provided with a continuous edge area whose outer boundary edge is provided with a seal for a resilient mounting of the support member against the inner cradles of a ventilation duct. Furthermore, a flat flexible membrane is attached to and thanks to the air-permeable surface of the entire support member. The membrane abuts overlapping against a part of the edge area of one side of the support member. This gives a total air flow compensation of the diaphragm against the continuous edge area of the support member against an air flow in one direction through the valve device. However, the membrane folds away due to its flexibility and allows an air flow opening through the support member in the opposite air flow direction. Because the membrane is sufficiently thin and at least partially flexible, a seal is obtained at very low river velocities and, correspondingly, a permeation also results at a slightly low river. However, it is also required that the inner fire has a certain stiffness in order to avoid deformation in the closing direction at the 3 air flow Than modern coke flats of about 100-500 l / s (liters / second). As an example of the very low river in properties with the natural system is 1 Ws. In mechanical exhaust systems, a thicker and stiffer membrane is required so that vibration noise does not occur at the base river, for example in bathrooms where the river speed is approx. 151 / s.
    The choice of material for the membranes should speak temperatures briefly up to 300 ° (degrees Celsius) and for continuous operation up to 265 °. These temperature limits are required to obtain a certain safety in case of fire in order to resist the intrusion of smoke and flue gases into neighboring units. The choice of material for the edging against the inner cradles of the ventilation duct is also such that a certain fire hardness is achieved. Suitable materials for this seal are heat-resistant / refractory rubber or refractory textile / yarn depending on the heat hardness sought. The invention also relates to embodiments which meant that a flat flexible membrane is provided with a stiffening part, for example an aluminum layer, but still the membrane is flexibly designed along its attachment. In embodiments of the invention, the support member is provided with an opening support which defines the opening angle of the membrane to a maximum opening layer of 70 ° -80 ° opening angle Than barbed bearing. Without such a stand, the sides of the membrane can be opened to an opening angle of 90 ° and the membrane sides risk hitting each other and can even bend at the same hall in the event of a strong air pressure surge of a return flow. Alternatively, one can also adjust the angle of the opening post to effect a limitation of the flow through the support device by limiting the angle of the opening post to about 20 ° -60 °. This means that the opening support can be used for adjusting the flow through the support device.
    In embodiments of the invention, the diaphragm is attached to the support member along a centrally located lines connecting rail in the support member. The central location meant that the membrane opened symmetrically equally on both sides of this connection rail and a symmetrical flow characteristic was obtained through the support member past the membrane. In this embodiment, the support member may be rectangular or square to fit in a corresponding rectangular or square ventilation duct. In embodiments of the invention, the support member is circularly designed to fit in a cylindrical ventilation duct. In this embodiment, it is easier to obtain a good seal between the ventilation duct and the support means. In embodiments of the invention, the extent of the connecting rail coincides with a diameter in the circular support member. Thus, a corresponding symmetrical flow characteristic is obtained through the circular support member and past the membrane as previously indicated.
    In embodiments of the invention, the support member comprises a number of support members distributed over the entire air-permeable surface of the support member. These support elements aim to eliminate indentation tendencies of the diaphragm when this closes to a flood in the reverse direction and that the diaphragm can therefore stop being taken towards the edge area of the support member. It is essential that these standing elements together have a small surface area but are also sufficiently rigid and sparsely distributed over the entire flow area to relax through maximum flow. For example, for a circular support member with a diameter of 160 mm, it may be suitable with support elements oriented as a squared square square with an edge length of about 30-35 mm where the width of the straight support elements is about 2-3 mm. Rectangular slides and radially directed support elements also provide a corresponding support function of the membrane.
    Thus, in embodiments of the invention, the standing element forms substantially square or rectangular halls in the standing member.
    In embodiments of the invention, the membrane is made of a glass web containing linen fibers and coated with a surface layer of PTFE, i.e. polytetrafluoroethylene, to a proportion of about 53%. This coating material is marketed by the DuPont Group under the Teflon brand. Suitable membrane thicknesses for low flow are 0.1-1.0 mm, preferably 0.2-0.5 mm. But it is also possible with membrane thicknesses of 1.0-10.0 mm in applications for forced ventilation depending on the softness and the own elasticity of the membrane material and depending on the system pressure which may amount to 250 Pascal or more.
    In embodiments of the invention, the seam is designed to enclose the outer edge of the continuous edge area or is designed such that the outer edge of the continuous edge area is designed to partially enclose the seam. The fitting also helps to obtain a fixation of the support member in the ventilation duct. For a further fixation in the ventilation duct, the support member can be provided with support legs or support wings which abut against the inside of the ventilation duct or can be clamped for abutment against the inside of the ventilation duct.
    In embodiments of the invention, the planar flexible membrane is attached to the support member with a support rail located outside the membrane which preferably extends transversely across the entire support member with its support members supporting the membrane against the continuous edge area. Such a support rail entails a further stiffening of the membrane along its line of symmetry and thereby eliminates bending of the membrane along its attachment.
    In embodiments of the invention, a mounting handle is mounted on the centrally located linear connection rail. This embodiment entails a simple mounting of the support member in the ventilation duct and a check that the connecting rail, and thus the entire support member, is oriented vertically, which requires thin membranes for the membrane to function and not fold out or skew over a horizontal axis. If the orientation of the connection rail is horizontal, the diaphragm will stand on its own weight, especially with soiled diaphragms, and the non-return valve function would not work. Within the scope of the invention, the ventilation device with the non-return valve function can be designed as combinations of the above-mentioned features within the scope of the appended claims.
    Furthermore, the ventilation device in natural draft properties can be integrated with a poppet valve which enables an adjustment of the exhaust air. Alternatively, the ventilation device in properties with mechanical exhaust air can be integrated with a ventilation device that enables an adjustment of the air flow in mechanical exhaust air systems. In addition, the ventilation device can be integrated with a so-called FTX system with recycling and which includes integrated supply air devices and exhaust air devices which can be adjusted, these also contributing to an increased fire and fire gas protection in the system.
    A ventilation device according to the invention also makes it possible to reduce mains and expensive fire protection between fire cells as the device significantly reduces the risk of fire and fire gases spreading between spaces. A reduction of trunk lines increases the value of properties with such a ventilation device as valuable building space is freed up for the production of living space and greater architectural freedom. Brief description of the drawings The invention will now be described in more detail with reference to the accompanying drawing figures. The drawing figures show only principle sketches intended to facilitate the understanding of the invention. Figure 1 shows in a plan view an embodiment of the invention.
    Figure 2 shows on an enlarged scale a section A-A through the invention according to figure 1.
    Figure 3 shows an alternative design of a sealing detail of the invention.
    Figure 4 shows a side view of the invention according to figure 1 mounted in a ventilation duct.
    Description of the invention Figure 1 shows an embodiment of a ventilation device 10 in a basic embodiment which consists of a flat circular support member 11 provided with an edge socket 12. The support member 11 in turn consists of a continuous edge area 13 and a number of support elements 14 formed in a grid pattern with rectangular or square hall 15. One of the support members 14 is oriented vertically in the ventilation device and is provided with at least two screw / nut joints 16 which are oriented linearly along a vertical support member which can be referred to as a connecting rail 141 in the support member 11. The screw / nut joints 16 hailer fixed a flat flexible membrane 17 whose surface is indicated by a shadow pattern in the figure. The diaphragm 17 covers the entire air-permeable surface of the support member, i.e. all the rectangular or square Mien 15 and abuts against a part of the edge area 13 of one side of the support member for a total air flow replacement against the continuous edge area 13 of the support member against an air flow through one direction. Because the membrane abuts against the edge region 13 only through the membrane's own span, an air flow opening is also obtained through the support means for the air flow in the opposite direction. Although the ventilation device is shown in the figure as circular, rectangular designs are also conceivable within the scope of the invention.
    Figure 2 shows a section through the ventilation device 10 with the support member 11 and its connecting rail 141. The edge socket 12 encloses the outer edge 21 of the continuous edge area 13. The diaphragm 17 abuts along the entire connecting rail 141 and is mounted thereon with the two screws / nut joints 16. In addition, the diaphragm overlaps 17 the continuous edge area 13 beyond the outer boundary of the air flow openings 22, 23 to abut against the edge area 13. The figure also shows that a mounting handle 24 is mounted on the centrally located linear connection rail 141 with the two screws / nut connections 16. As a mounting alternative or mounting complement, Figure 2 shows a support rail 25 placed outside the diaphragm 17, shown in broken lines in the figure. The support rail 25 preferably extends over the entire support member 11 with its supporting member 17 against the continuous edge area 13. Such a support rail 25 can also be mounted with the two screw / nut connections 16. The figure also shows an alternative embodiment where the support member 11 is provided with four opening posts 26 which define the opening angle of the membrane. Two of the opening posts define one side of the opening angle of the diaphragm and the other two opening posts define the other side of the opening angle of the diaphragms. The figure also shows a central mounting hall 27 which can be used for additional screw / nut connections, for example when a support rail 25 is used.
    Figure 3 shows an alternative design of an edge socket 32 which is partially enclosed by the outer edge 33 of the continuous edge area 13. The figure shows that the outer edge 33 is formed with a groove 34 in which the edge socket 32 is mounted. Otherwise, the valve device works as previously described.
    Figure 4 shows an embodiment of the valve device 10 mounted in a ventilation duct 41 with an exhaust air flow marked with the solid arrow and with an alternative return flow marked with the dashed arrow. The ventilation device connects and tugs to the inside of the ventilation duct through the edge grooves 12 and 20 is oriented vertically with the mounting handle 24 for the fastening of the membrane 17 to allow a vertical bending line for the membrane whose [Dada sides fold out when an exhaust air flow (the solid arrow) acts against. As can also be seen from the figure, an alternative is shown where the ventilation device is provided with opening post 26 which limits the opening angle of the membrane to 70 ° -80 ° from a closed position. The opening post 26 is designed as vertically angled arms but can alternatively be designed as horizontal arms or angle-limiting discs. An embodiment of the opening post is that it is designed as an aluminum member which is mounted outside the diaphragm and which can be bent to a suitable maximum limiting angle for the diaphragm. The shape of this aluminum member may be as alit from a disc with up to the same diameter as the diaphragm to different wing shapes and to arms shown in Figure 4 or as arms with other shapes and angles than those shown in Figure 4. 8
