Definitions

  • the present invention relates to an air duct box, in particular wall box, as an insert in a building wall with a ventilation opening for supply and / or exhaust air, which is closable by means of a movable from a closed position to an open position closure.
  • Prefabricated wall boxes for ventilation of buildings as a form of the generic air duct boxes are known in a variety of configurations.
  • the ventilation boxes are used to create an opening in the wall of a building for the supply of incoming and / or exhaust air.
  • a building wall is not only a wall, but also roofs, glazings, insulated panels and panels and the like into consideration.
  • the possibility of carrying air streams through the building wall through as incoming or outgoing air can result for different reasons, for example, to dissipate odorous exhaust air or used room air, or to introduce fresh or cooling air into the building.
  • a generic air duct box is for example in the Laid-open application DE 39 39 658 A1 disclosed.
  • a pivotally mounted closure is included in this air guide box. If this is in its closed position, no exhaust air can escape to the outside and no supply air can penetrate into the fan tube. By the closure of the air duct box is prevented in this way in particular that with the escaping exhaust air and a part of the building heat is lost.
  • Closure mechanics oppose the supply or exhaust air flow a significant flow resistance and thereby the throughput of connected to the respective air guide box fan units, such as cooker hoods, clothes dryers, Toilettenldividerer, air conditioners, heat exchangers and the like, is significantly affected.
  • WO 01/71261 describes a valve device for controlling the air flow.
  • the device consists of a cylindrical fan tube, in which a likewise cylindrical sleeve is inserted.
  • a disk unit with a disk is attached to one end of the sleeve, which is located outside of the fan tube. At this end, the sleeve has slots through which air can flow.
  • the disc is provided with a sound-absorbing fiber mat and in the sleeve, a filter device is provided for filtering dirt particles.
  • DK 172353 describes a ventilation valve for the intake of outside air.
  • a fixed cylindrical fan tube on the outside of a building wall protrudes out of this.
  • another cylindrical tube is slidably mounted with kieinerem diameter, which is lined on its inside with an insulation.
  • the end of the cylindrical fan tube, where the outside air is received, is closed and has on its inside an end insulation.
  • the outside air can flow in the open state of the ventilation valve via a slot which is provided in the side wall of the cylindrical fan tube.
  • an air guide box on the one hand has a good thermal external insulation and in which the closure in the supply or exhaust air operation causes only the lowest possible flow resistance to the supply or exhaust air flow.
  • the closure should close the fan tube in its closed position possible good sealing.
  • an air guide box according to claim 1, by the closure is provided with a thermal insulation, which is positionable in the closed position of the closure in a portion of the fan tube and in the open position of the closure outside the fan tube.
  • the potential for heat losses caused by the air guide box is significantly reduced.
  • the ability to move the thermal insulation in the open position of the closure in a position outside the fan tube, the flow resistance is not increased by the thermal insulation in such a product design.
  • the thermal insulation of the air duct box for the periods in which no supply or exhaust air are sucked in or blown out through the air guide box the throughput of the connected to the air guide box hood during their operation is not adversely affected.
  • With a favorable design of the linkage, of which the closure is held with the thermal insulation it is even possible to lower the flow resistance of the air guide box against the incoming or exhaust air flowing through it compared to the previously known air duct boxes.
  • the suction of a connected ventilation device such as a hood, heat pump or air conditioning can be increased.
  • the air guide box according to the invention can be produced inexpensively. So it is possible to produce the fan tube made of commercially available PVC pipes.
  • the PVC pipes can be bought cheaply and in many cross-sectional sizes.
  • the PVC pipes transmit little heat energy through their walls.
  • the PVC pipes can be cut in any length, so that an air guide box in a simple manner to the wall thicknesses of the respective building wall, in which it is to be installed, is adaptable.
  • the PVC pipes are corrosion-free and can easily be used with cement, silicone or gypsum in existing building walls.
  • the round tube cross-section makes it easy to cut accurately fitting holes with rotating tools in building walls. In this way, the air guide box according to the invention can also be retrofitted at any time in existing buildings with little effort. For the installation, it does not matter whether the relevant building wall has a single or multi-shell construction.
  • Fig. 1 is an air guide box 2 to see, which consists essentially of a fan tube 3 with a vent 4 and a closure, which consists essentially of an insulator 8 and a lid 10 is constructed.
  • a fan tube 3 with a vent 4 a vent 4
  • a closure which consists essentially of an insulator 8 and a lid 10 is constructed.
  • the respective components are clearly visible.
  • the fan tube 3 is shown as a round tube, but it may also have other suitable tube cross-sectional shapes, such as quadrangular, hexagonal, trapezoidal and the like.
  • the fan tube 3 can be inserted into a sufficiently large opening of a building wall.
  • the connection with a masonry as an example of a building wall can be done by cement or gypsum, which can be filled in the air gap between the outer surface of the fan tube 3 and the inner surface of the building wall opening.
  • adhesive bonds with adhesives, PU foam, silicone and the like are possible.
  • the fan tube 3 may have such lengths that it can be used in common building walls, or the fan tube 3 is supplied in excess and can be shortened by sawing the protruding part to a suitable length.
  • the fan tube 3 is made of a PVC material, but it can also be used as a material other plastic materials, metal, clay and the like.
  • Fig. 1 is in dashed. Lines indicated where the insulating body 8 is in the closed position of the shutter 6.
  • the length of the distance S, by which the shutter 6 is displaced from the open position to the closed position, is greater than the thickness D of the insulator 8.
  • Fig. 1 is clearly visible that the insulating body 8 is immersed as a thermal insulation of the shutter 6 with its entire thickness D in the closed position in the fan tube 3. Between the outside air and the remaining cavity in the fan tube 3 results in a highly effective thermal insulation, can be reduced by the heat losses through the shutter 6 to a minimum.
  • the open position of the closure 6 allows unimpeded outflow of the exhaust air from the and an unimpeded inflow of supply air in the air guide box 2. In this way, an excellent thermal insulation in conjunction with a minimum flow resistance against the respective air flows is realized.
  • the insulating body 8 can be inexpensively made of a polystyrene or PU foam material. These materials provide excellent thermal insulation properties while still being lightweight and cost effective. As an insulating 8, however, a plug can be used which has an inner provided with a vacuum insulating space. Other known solutions for thermal insulation can be realized in the insulating body 8.
  • the insulating body 8 has an outer shape, the cavity shape of the ventilation opening 4 and / or the fan tube 3 in the closed position of the insulating body 8 is adapted at least almost sealing. Due to the at least nearly sealed shape is avoided that occur laterally on the insulator 8 termeistichde air flows heat losses. However, the insulating body 8 with its shape may not sit too tightly in the closed position in the fan tube 3, as this would affect the opening and closing of the shutter 6 too much. Here a suitable compromise must be found. Alternatively or in addition to the almost sealing fit of the insulating body 8 may be provided with one or more sealing rubbers which slide on retraction and extension of the closure 6 on the inner surface of the fan tube 3 and sealing by a certain inherent flexibility both to the shape of the insulating.
  • the seals can be arranged on the insulating body 8 or in the inner wall of the fan tube 3.
  • the closure 6 has a cover 10 which protrudes laterally beyond the outer circumference of the insulating body 8 and also over the outer periphery of the end face of the fan tube 3.
  • the fan tube 3 can be sealed well in the closed position of the closure 8 to the outside.
  • the cover 10 is provided on the fan tube 3 side facing with a flexible support 20 such as a foam rubber pad. In the closed position of the closure 6, the cover 10 seals - possibly with the additional flexible support 20 - the fan tube 3 from wind, rainwater, dust, insects and other foreign matter, which can not penetrate into the fan tube 3.
  • the lid 10 may be provided with an attractive coating or paint, so that the air guide box 2 fits unobtrusively into the optical image of the surrounding building wall.
  • the visible in the known wall boxes air vents or slats omitted.
  • the fan tube 3 or the insulating body 8 are no longer visible in the closed position of the closure 6 because of the protruding lid 10. This results in an overall very attractive appearance of such air duct 2.
  • the closure 6 is adjustable by means of an adjusting mechanism 12 which is arranged in the ventilation opening 4 and / or in one of the ventilation opening 4 upstream pipe section of the fan tube 3.
  • the adjusting mechanism can be manually or motor-operated, in particular by an electric motor.
  • the adjusting mechanism 12 consists of a rotatably driven spindle tube, by the operation of the shutter 6 changes its spatial position.
  • Toggle mechanisms, telescopic tubes and the like can be realized as an actuating mechanism 12. Due to the arrangement of the actuating mechanism 12 in the ventilation opening 4 or in another pipe section of the fan tube 3, the installation dimension of the air duct 2 remains limited to the cross section of the fan tube 3 There are no separate space for the control mechanism 12 required to create the expensive and also against thermal To isolate losses.
  • seals against pressure losses of the flowing air streams are not required in this embodiment.
  • the actuating mechanism 12 By embedding the actuating mechanism 12 in the fan tube 3, these can hardly be damaged during transport and dismantling and is housed very protected.
  • the adjusting mechanism 12 takes only a small space, so that increased by the adjusting mechanism 12 of the flow resistance against the exhaust air flow not in appreciable extent.
  • a drive or an adjusting mechanism can also be arranged outside of the fan tube 3.
  • a linkage 14 is present in the air guide box 2, which is designed so that it on the inner surface of the ventilation opening 4 and / or the vent 4 upstream pipe section 16 of the fan tube 3 at least slid in sections sliding.
  • the closure 6 is held by the support also stable in its open position, in which this may be exposed to high wind forces or a fire with a football under certain circumstances.
  • the construction of the air duct box 2 proves to be extremely reliable and robust against interference from external influences.
  • the linkage 14 may have a lattice structure 18 in a section through which, in an open position of the closure 6, the penetration of larger foreign bodies into the ventilation opening 4 is made more difficult.
  • the lattice structure 18 is preferably arranged such that the closure effect with respect to the ventilation opening 4 results, in particular in the open position of the closure 6.
  • the grid structure 18 may be formed so as to additionally stabilize the linkage 14.
  • the linkage 14 and the grid structure 18 should be designed so that they produce only the lowest possible flow resistance against a sweeping air flow. For this reason, the corresponding components should have only the smallest possible material thickness transversely to the flow direction of the air flow exhibit. A sufficient stability of the components can still be achieved by the material for the corresponding components is more arranged in a parallel extension to the flow direction of the guided through the fan tube 3 air flow.
  • the grid of the linkage 14 may be made for example of a galvanized sheet steel or a tough plastic with, for example, only one millimeter material thickness, with the stability of the components of the several millimeters and possibly even centimeters wide webs results parallel to the flow direction of the air flow.
  • Is a motorized actuator for the displacement of the shutter 6 between an open and closed position present it is advantageous to combine the circuit with the circuit of the connected ventilation unit, as will be explained below using the example of a cooker hood.
  • About an electrical connection can be actuated with a switch arranged on the hood switch and the actuator. It is particularly favorable if the actuator can be actuated by the on / off switch of the extractor hood. In such an embodiment, it is possible to turn on by turning on the hood at the same time the servomotor, by which the shutter 6 is moved from the closed position to the open position.
  • the extractor hood can therefore always be operated with optimum performance.
  • a separate switch can be provided on the hood, through which the user can preselect and adjust the operating position of the shutter 6 separately.
  • the insulating body 8 In order to ensure that the insulating body 8 always reliably slides into the ventilation opening 4 during a closing movement of the closure, it is advantageous if at least one side wall section of the closure 6, in particular a section of the insulating body 8, has a conical or trapezoidal shape tapering towards the adjustment path.
  • the insulating body 8 has on its the fan tube 3 side facing a frusto-conical portion which automatically centers the insulator 8 at a run-up of the inclined surface of the end edges of the fan tube 3 and ensures a precisely fitting inlet into the vent opening 8. Even if, after prolonged use, individual mechanical components of the actuator or the adjusting mechanism should have a certain play, this can be compensated by the centering function of the inclined surfaces. In this way, a permanent reliability of the air duct 2 is ensured.
  • the fan tube 3 may have a corresponding shape design.
  • Fig. 2 is a view of an air guide box 2 with an open closure 6 shown. It is easy to see how the exhaust air in the open position of the closure 6 can escape laterally past this into the ambient air. Supply air can easily flow into the ventilation opening 4.
  • FIG. 3 the air guide box 2 is shown, in which the shutter 6 is in its closed position. In this view, it can be clearly seen that only the lid 10 of the closure is visible from the outside of the entire air guide box 2.
