Definitions

  • the present invention relates to a ventilation device, which defines a venting channel opening into a space to be ventilated and comprises a closure element arranged in the ventilation channel, which can be moved between an open position and a closed position as a function of the air humidity in the space to be ventilated.
  • a formed by a braided band hygrometric actuator is provided whose length varies depending on the humidity.
  • the hygrometric actuator is fixed at one end to a frame of the device and at the other end connected to a slidingly mounted on the frame part, which is acted upon by a spring in the direction of expansion of the hygrometric actuator.
  • the spring element and the moisture-sensitive element are connected via the mounted on the frame of the device part, a displaceably mounted on this part further part and a crank with the flap provided as a closure element, wherein the two parts are each designed as a kind of slide.
  • the invention has for its object to provide an improved ventilation device of the type mentioned, which is kept as simple as possible Construction ensures a reliable, depending on the humidity automatic ventilation.
  • the closure element can be actuated via an automatic setting unit comprising a spring element and a moisture-sensitive element held stretched by the prestressed spring element, wherein the closure element increases with increasing humidity by correspondingly increasing relaxation of the spring element due to the increasing length of the moisture-sensitive element in the opening direction and with decreasing air humidity can be acted upon in the closing direction due to the moisture-sensitive element contracting against the spring force, and the connection between the adjusting unit comprising the spring element and the moisture-sensitive element and the closure element comprises an elastic band.
  • the elastic band is preferably designed and arranged such that it can absorb and transmit both tensile and compressive forces in the longitudinal direction.
  • the moisture-sensitive element preferably comprises an elongated element, in particular a moisture-sensitive tape, which may in particular be a moisture-sensitive plastic tape.
  • a moisture-sensitive tape which may in particular be a moisture-sensitive plastic tape.
  • Such tapes are well known as such.
  • the spring element may in particular comprise a tension spring, in particular a helical tension spring.
  • the tension spring can be arranged parallel and in particular in extension of the moisture-sensitive element.
  • the closure element advantageously comprises a flap pivotable about an axis.
  • the moisture-sensitive element and / or the tension spring are arranged parallel to the axis of the pivotable flap.
  • one end of the moisture-sensitive element is fixed and its free end connected to the spring element.
  • the closure element is preferably coupled to the connection point between the moisture-sensitive element and the spring element.
  • the adjusting unit comprising the spring element and the moisture-sensitive element is expediently coupled to the closure element via a lever mechanism.
  • the lever mechanism for example, comprise an eccentrically mounted shaft, a crank or the like.
  • a locking element for locking the closure element is provided in its closed position, by which the spring element is independent of the existing humidity in its biased position fixable.
  • the spring member can not relax even with increasing humidity, the moisture-sensitive member is prevented from expanding in length.
  • the closure element thus remains in its closed position despite increasing humidity. Only after the spring element is released from the adjustable locking element again, the closure element can be acted upon with increasing moisture again in the opening direction.
  • the locking element may for example comprise a pivotally mounted about an axis lever or the like.
  • the ventilation device preferably comprises a housing provided with ventilation openings, in which in particular the closure element, the setting unit, the spring element and the moisture-sensitive element are integrated.
  • the lever mechanism, the elastic band and / or the locking element may be integrated in the housing.
  • the ventilation device according to the invention can be mounted, for example, in an opening in a wall or ceiling delimiting the space to be ventilated, on or in a frame or on or in a window or door leaf.
  • Fig. 1 to 3 show a schematic representation of an end portion of an exemplary embodiment of a ventilation device 10 according to the invention.
  • the ventilation device 10 defines a ventilation duct 12 opening into a space to be ventilated and comprises a closure element 14 arranged in the ventilation duct 12, which can be moved between an open position and a closed position as a function of the air humidity in the space to be ventilated.
  • the closure element 14 can be actuated via an automatic setting unit 16, which comprises a spring element 18 and a moisture-sensitive element 20 held stretched by the prestressed spring element 18.
  • the moisture-sensitive element 20 responds to the humidity in the room to be ventilated and expands with increasing humidity, while it contracts again with decreasing humidity.
  • the closure element 14 with increasing humidity by correspondingly increasing relaxation of the spring element 18 due to the increasing length of the moisture-sensitive element 20 in the opening direction and acted upon by decreasing humidity due to the moisture-sensitive element 20 reclosing against the spring force in the closing direction.
  • the length of the moisture-sensitive element 20 thus increases, as a result of which the prestressed spring element 18 that holds this moisture-sensitive element 20 can relax accordingly.
  • the extent to which the spring element 18 relaxes depends on the increase in air humidity.
  • the closure element 14 With relaxing spring element 18, the closure element 14 is acted upon more or less in the opening direction depending on the extent of the increase in air humidity.
  • the moisture-sensitive element 20 retracts more or less together with decreasing humidity, whereby the closure element 14 is acted upon in the closing direction accordingly.
  • the moisture-sensitive element 20 may comprise, for example, a moisture-sensitive tape, in particular a moisture-sensitive plastic tape.
  • the spring element 18 may comprise, for example, a tension spring, in particular a helical tension spring.
  • the closure element 14 comprises a pivotable about an axis 22 flap. In principle, however, a different type of closure element is conceivable.
  • the closure element 14 is coupled to the connection point 26 between the moisture-sensitive element 20 and the spring element 18 or an area adjacent to this connection point 26.
  • a lever mechanism 28 may be provided for coupling the spring element 18 and the moisture-sensitive element 20 comprehensive setting unit 16 to the closure element 14.
  • the lever mechanism 28 as shown, for example, comprise an eccentrically mounted shaft or crank 30.
  • connection between the adjusting unit 16 comprising the spring element 18 and the moisture-sensitive element 20 and the closure element 14 can, as shown, moreover comprise an elastic band 32 which can be subjected to pressure and tensile stress in particular.
  • this elastic band 32 is connected to the joint 26 between the moisture-sensitive element 20 and the spring element 18 and the other end to the lever gear 28 and its eccentric shaft or crank 30.
  • the elastic band 32 is guided in a guide 33 in order to be able to transmit both tensile and compressive forces in the longitudinal direction.
  • Fig. 1 shows the ventilation device 10 in a schematic, partially sectioned partial side view.
  • Fig. 2 the ventilation device 10 is shown in a schematic perspective partial representation.
  • the ventilation device 10 may comprise a vented housing 36 in which the closure element 14, the actuator 16, the spring element 18, the moisture sensitive element 20 and optionally also the elastic band 32 are integrated.
  • Fig. 3 shows a view of the closure member 14, the actuator 16 and the elastic band 32 of the ventilation device 10 according to Fig. 1 from below, with the housing 36 omitted for clarity.
  • the venting device 10 may further comprise a locking member 34 via which an end portion 46 of the moisture-sensitive element 20 for locking the closure member 14 is acted upon in its closed position so that the end portion 46 connected to the spring element 38 with increasing moisture in its biased Position is fixed. At the same time, the moisture-sensitive element 20 is prevented from expanding.
