Definitions

  • the invention relates to a closure arrangement for an air duct and a corresponding building arrangement.
  • the FR 1 438 716 A describes a closure arrangement for an air duct, comprising a channel and at least two closure elements arranged in the channel, wherein the closure elements between an open position in which the closure elements release a cross section of the channel, and a closed position, in which the closure elements at an inner periphery of the channel sealing and closing the channel, are pivotable, wherein the closure elements along the longitudinal axis of the channel and in an air flow direction through the channel are spaced apart from each other, so that in the closed position between the closure elements, a fluid-sealed space is formed, and wherein the Closing elements each have two flaps.
  • a similar closure arrangement also describes the US Pat. No. 1,470,262 A , Further closure arrangements are known from DE 20 2006 004 839 U1 , of the DE 198 49 863 A1 and from the DE 20 2010 003 340 U1 known.
  • a wall box in which a closure lid between an open position and a closed position driven by a pressure difference between the air pressure inside and outside the building against a self-adjusting mechanism provided by a restoring force automatically opens and closes.
  • the known wall boxes often have the disadvantage that they represent a thermal bridge between the building interior and the building environment.
  • it is from the DE 20 2006 006 327 U1 known to use in a wall box a motor displaceable between a closed and open position shutter which has an insulating body which has an outer contour which substantially corresponds to the inner contour of a ventilation duct.
  • the adjusting mechanism is designed to displace the insulating body in a linear movement between the open and the closed position.
  • the closure system is thus formed comparatively complex and in particular does not allow the automatic opening of the closure due to an incipient air flow, as generated for example by hoods for the removal of fumes.
  • the closure arrangement is characterized in that the two flaps of the closure elements along its circumference have a hinge side whose length corresponds to an inner dimension of the channel, and otherwise a sealing contour which is adapted to a contour of the inner circumference of the channel, wherein the two flaps each closure element are arranged adjacent to one another with their hinge sides and are folded toward one another in the open position and extend along the longitudinal axis of the channel, extend parallel thereto, or extend at an angle thereto, wherein the flaps have a dimension perpendicular to their respective hinge side , which is greater than the distance of the closure elements to each other, so that in the open position in each case one of the flaps of a first closure element of the closure elements with one of the flaps overlaps at least one further closure element of the closure elements.
  • the closure arrangement according to the invention thus makes use of the significantly lower thermal conductivity of air compared to most solids.
  • the enclosed between each two adjacent closure elements air volume acts just like a warmth.
  • the closure arrangement according to the invention is not restricted to a specific number of the closure elements used. Already two closure elements are sufficient to form the thermal barrier according to the invention in the form of a closed volume of air. Investigations have shown, however, that closure arrangements can be realized on the basis of the teaching according to the invention which already have a heat transfer value of only approximately 1 W / (m 2 K) using three closure elements.
  • the flaps may be formed, for example, as one-sided beschamêt Arthur plastic flaps.
  • the flaps When the channel is a circular channel, the flaps may have substantially the shape of a half circular disc, with the straight side of the flap forming the hinge side.
  • the volume of air trapped between the closure elements in the closed position of the closure arrangement in the longitudinal direction of the channel can only have a comparatively small dimension, which may for example also be smaller than the radius of a used circular channel.
  • the overlapping flap sections of the adjoining closure elements are to be arranged such that the closure arrangement forms as low a flow resistance as possible in the open position.
  • the flaps each have a step which extends spaced from the hinge side and parallel to the hinge side by the distance between the closure elements, so that the flaps lie in an overlapping region of the flaps and thus due their compact arrangement only have a very small cross section for the air flowing through the channel.
  • the flaps are arranged as close to each other as possible in the open position and to largely suppress rattling of the flaps due to turbulence in the open position, at least a first of the closure elements, for example their side facing the hinge side having a spoiler having a raised portion via a step, which is arranged in the open position flaps in the overlapping region at a distance from a flap of another of the closure elements, which is arranged downstream of the first closure element is, so that the overlapping flaps are pressed against each other via an output of the flap having the spoiler, when the closure elements are flowed in the open position of an air flow.
  • a first of the closure elements for example their side facing the hinge side having a spoiler having a raised portion via a step, which is arranged in the open position flaps in the overlapping region at a distance from a flap of another of the closure elements, which is arranged downstream of the first closure element is, so that the overlapping flaps are pressed against each other via an output of the flap having the spoiler
  • the flaps are designed as cavity profiles which have an enclosed gas volume.
  • the flaps themselves can for example be made of a plastic material, in particular of a plastic material with a low coefficient of thermal conductivity, for example by injection molding.
  • the adjoining hinge sides of the flaps of each closure element are interconnected via an airtight web, wherein the airtight web may comprise a spring-actuated return element which, in the open position of the flaps, provides a restoring moment in the closed position.
  • the restoring element can be designed, for example, in the form of an elastic rubber spring element, in which the hinge sides of the flaps are inserted at opposite longitudinal grooves. If the flaps are flown by an air flow, the flaps move under bias of the return spring element in the open position. If the air flow stops, the flaps are moved back into the closed position due to the restoring moment of the preloaded spring element.
  • the flaps have a curved contour with a convex outer side and a concave inner side. Especially if the flaps partially overlap adjacent closure elements in the open position, the above-described curved contour of the flaps has the advantage that the closure assembly forms only a low flow resistance.
  • the sealing contour comprises a compression seal, such as a rubber lip or a foam element, or a brush element, so that in the closed position between the inner circumference of the channel and the sealing contour, an impact gap is formed instead of an impact gap.
  • the channel has an inner contour with varying diameter in the channel longitudinal direction, wherein the inner contour has chamfers along which the flaps are guided during their movement from the open position to the closed position with compression of the compression seal.
  • the run-up slopes thus also have the function of forming a stop for the flaps in their movement between the open position and the closed position.
  • an adjusting drive on the movement of the closure elements between the open position and the closed position
  • this can be realized according to an embodiment of the invention such that the adjustment acts on the flaps of the rearmost in the air flow direction closure element, wherein the overlapping flaps with each other via coupling elements coupled together.
  • the adjusting drive can then be surrounded in the open position by the flaps of the rearmost element in the air flow direction, or be in the slipstream of the closure elements.
  • the adjustment is not only aerodynamically arranged, but also effectively protected from contamination, such as those contained in the vapors of a cooker hood.
  • the coupling elements as a coupling rod, a Coupling rod or a coupling thread are formed, or have such elements, which extends at an angle 0 ° ⁇ ⁇ ⁇ 90 ° to the longitudinal axis of the channel and is thus connected at a different distance to the hinge sides with the overlapping flaps.
  • an embodiment in which the closure arrangement is of modular design, in order to enable, at the discretion of the user and depending on a specific application situation, an efficient adaptability of the closure arrangement to the conditions encountered. It is provided that the channel is divided longitudinally into a plurality of channel sections which are releasably connected to each other, wherein in each of the channel sections of the closure elements is received. This embodiment makes it possible for any number of the channel sections with closure elements accommodated therein to be combined to form a closure arrangement according to the invention.
  • the closure arrangement according to the invention can in particular also be used for retrofitting in already existing exhaust air duct systems. It is often the case that an already found wall box in a wall breakthrough of a building wall has an air passage cross-section with a deviating from the standard geometry. For example, an inserted in the wall breakthrough channel due to its installation situation have rounding, which makes the installation of a closure assembly for standardized pipe cross-sectional geometries difficult.
  • the closure elements via an adjustment between the open position and the closed position are movable back and forth, wherein the adjustment Has at least one spring element which exerts a closing moment in the closed position on the closure elements.
  • the closing moment exerted by the spring element on the closure elements is degressive, increases in the direction of the closed position and is maximum in the closed position.
  • the channel is provided on its inner circumference per closure element with a circumferential spoiler which extends from a channel inside and forms a local channel cross-sectional constriction, wherein the closure elements in the closed position at a free end edge of the building wall each jewel wall breach in which a wall box is used with a Lucas miclassqueritessgeometrie, wherein in the wall box, a closure assembly according to any one of claims 1-16 is inserted.
  • the channel has an outer geometry, which differs from the Heil miclassquerroughsgeometrie.
  • a diameter compensation element for example a circumferential, elastic sealing element is arranged, which is designed to compensate for the deviation between the channel outer geometry and the Vietnamese manlassgeometrie.
  • the outer dimensions of the channel are slightly undersized, in which case the required, fluidly sealed closure between the channel and the wall box is ensured by means of the compensating element.
  • FIG. 1 shows in longitudinal cross section a simplest embodiment of the invention in a schematic representation.
  • the left-hand opening of the channel 1 in the illustration forms the air inflow side, and accordingly the right-hand opening in the illustration is the air outflow side of the channel 1.

  • the elastic webs 9 are biased so that they act in the open position as a return spring element, which exerts a restoring moment in the direction of the closed position on the flaps 3.
  • closure element 2 engages an adjustment 10, with which the flaps 3 can be transferred against the bias of the webs 9 from the closed position to the open position.
  • Adjacent flaps of adjacent closure elements are operatively coupled to each other via coupling elements 11.
  • the flaps 3 are formed as hollow profiles and thus have over solid material flaps improved thermal insulation properties.
  • the flaps 3 are shaped so that they are in the in FIG. 2 illustrated open position of the closure assembly represent the lowest possible air resistance and shield the adjusting member 10 to avoid air vortices and its contamination. Due to the curved outer contour of the flaps 3, the closure assembly forms an outer geometry in the open position, which has a low air resistance.
  • the flaps 3 of the closure elements 2 are optimized in such a way that the closure arrangement in the open position, on the one hand, forms the least possible air resistance and, on the other hand, rattling of the flaps 3 is effectively suppressed due to turbulence on the closure arrangement.
