Definitions

  • the invention relates to a ventilating device comprising a housing substantially elongated in the width direction and provided with a slotted ventilating duct which terminates at one end in an outer mouth breaking through a first housing wall part and at its other end in an inner mouth breaking through a second housing wall part, which ventilating duct is at least partly bounded by plate-shaped elements, including a pivotally arranged valve element which is arranged near the inner mouth and can be brought by an operating mechanism from an open position in which the passage of the ventilating duct is at its maximum, via a number of intermediate positions to a position closing the ventilating duct.
  • Such a ventilating device is known from GB-A-2 309 776.
  • a ventilating device Built in a window, a casing or a wall which separates a space in a building from the surroundings of the building, such a ventilating device provides the supply of fresh air to this space.
  • this supply can be controlled, which is done with the operating mechanism by a person present in the space to be ventilated.
  • the operating mechanism is arranged on the side of the inner mouth, so that, from a structural viewpoint, the valve element is preferably placed at this inner mouth and the pivot pin of this valve element is also arranged on the inner mouth side thereof.
  • a relatively simple operating mechanism for the valve element can be realized.
  • the formation of the stepped transition when placing the valve element in an intermediate position also occurs with another type of ventilating device, namely the type with a rotating valve, as known from DE-A-31 20 694.
  • valve element is of such design that when the valve element is in an intermediate position the duct passage, viewed in a direction from the outer mouth to the inner mouth, is gradually, that is to say substantially steplessly, reduced by the valve element, as compared with the passage in the open position.
  • the above effect can be obtained, for instance, by extending the valve element in the above-discussed known construction by a more or less flexible flap or by a plate-shaped part which, on the one hand, is hingedly connected with the above-mentioned free edge of the valve element, and which, on the other hand, can freely slide along the lower wall of the ventilating duct.
  • the plate-shaped part lies flat on the lower wall, while when the valve element is placed in an intermediate position the plate-shaped part is taken along by the valve element and thus comes to lie in a position slanting upwards, viewed in the direction of flow.
  • valve element is a substantially plate-shaped member which is hinged on a pin located at the end edge of the valve element directed towards the outer mouth, and in which the operating mechanism is provided with a lever extending at the inner mouth to outside the housing, with which lever the pin can be rotated and thus the valve element can be pivoted.
  • the pin then comes to lie at some distance within the housing of the ventilating device.
  • the lever carries a gear wheel which gears with a gear wheel mounted on the pin.
  • the free end of the valve element is located at the inner mouth in the form of a movable end edge. If it is considered desirable to have a widening configuration at the inner mouth also in an intermediate position, this can be realized if a second plate-shaped member connects to the plate-shaped member, which second plate-shaped member makes such an angle with the first plate-shaped member that at the inner mouth the relevant widening configuration is obtained.
  • the free end edge is kept out of sight as much as possible when looking into the ventilating device at the inner mouth, when the second plate-shaped member is hingedly connected with the first plate-shaped member, so that when the first plate-shaped member pivots upwards the second plate-shaped member can pivot downwards.
  • Another possibility is to extend the valve element by a flexible flap.
  • the air resistance is kept as low as possible, in particular in the open position, it is preferred that at least a part of the first plate-shaped member not connecting to the pin extends in the direction of the inner mouth divergently with respect to the opposite wall partly determining the ventilating duct. In order that the air resistance is kept as low as possible also in all the intermediate positions, it may further be preferred that an elastic flexible sheet-like part lies over the valve element.
  • the inward displacement of the pivot pin may be a reason, as mentioned above, to arrange a gear wheel transmission between the pivot pin and an operating lever.
  • a gear wheel construction may be omitted if the operating mechanism engages the first or the second plate-shaped member at a distance from the pin.
  • valve element is adjustable by a motor and is provided with a control unit for adjustment to a specific throughput, in which connection a sensor is arranged in the ventilating duct, which sensor applies signals to the control unit for keeping the throughput constant, and which sensor is placed in the ventilating duct part before the pivotable valve element.
  • a control unit and a sensor an automatically controlled ventilating device is obtained, that is to say a ventilating device which can be adjusted to a specific throughput, and which independently keeps this throughput constant by readjusting the position of the valve element.
  • the readjustment is controlled depending on control signals from the sensor.
  • the ventilating device very schematically shown in Fig. 1 comprises a housing 1 largely filled with sound-damping material 2, in which a ventilating duct 3 is provided.
  • the ventilating duct 3, which has an outer mouth 4 and an inner mouth 5, may be bounded by sound-damping material 2 or by plate-shaped elements, one of which is a valve element 6, which is hinged on a pin 7, and which is shown in the open position, that is to say the position in which the ventilating duct 3 has its maximum passage. Pivotation of the valve element 6 to the position closing the ventilating duct 3 takes place by pulling the operating rod 8, which is hingedly connected with a lever 9, which, in turn, is fixed to a disk 10.
  • the disk 10 is rotatable on a pin 11 and is provided on its outer circumference with teeth, not shown, which gear with teeth, likewise not shown, of a disk 12 mounted on the pin 7 and rotatable together with this pin.
  • the valve element 6 is pivoted upwards, for instance to an intermediate position 6' or an end or closing position 6'', in which the passage of the ventilating duct 3 is entirely closed.
  • the intermediate position 6' the pivotation of the valve element 6 results not in an abrupt, but in a gradual reduction of the passage of the ventilating duct 3.
  • the valve element rotates on the pin 11, which valve element then comes to form a vortex chamber in the ventilating duct.
  • valve element is then extended in the direction of the outer mouth 4 with a plate-shaped part, which, in the place where in Fig. 1 the pin 7 is indicated, is hingedly connected with the valve element, and which is further loosely supported on the lower wall of the ventilating duct.
  • the hinge edge is pulled upwards along with the plate-shaped part, while the opposite free edge thereof slides over the lower wall of the ventilating duct in the direction of the inner mouth 5.
  • the plate-shaped part comes to form an upwardly slanting surface, to which the valve element connects as a downwardly slanting surface, which results in a continuous, gradual and stepless narrowing and then widening of the ventilating duct with as less disturbance of the air flow as possible.
  • a more or less flexible flap may also be used.
  • a similar ventilating device is shown as in Fig. 1.
  • the valve element 6 is provided therein with a bent connecting part 13, which results in a directedly widening configuration also in the intermediate position, indicated by 13'.
  • a sensor 14 which measures the velocity of the air flow through the ventilating duct 3.
  • the measuring value of the sensor 14 is passed to a control unit, not shown, which can control a motor, likewise not shown, which motor can rotate the pin 7 of the valve element 6.
  • a control unit not shown, which can control a motor, likewise not shown, which motor can rotate the pin 7 of the valve element 6.
  • a similar ventilating device is shown as in Fig. 1.
  • the bent connecting part 13 shown in Fig. 2 is replaced therein by a part 15 attached to the valve element 6 via a hinge 16.
  • this embodiment comprises an operating mechanism in the form of a sliding button 17 with a slotted hole guide 18, into which a pin stud 19 extends, which is attached to the end of the part 15. By pushing the sliding button 17 upwards, the valve element 6 can be brought from the open to the closed position, indicated by 6', 15'.
  • a ventilating device which comprises a housing 21 which, together with a valve element 26, defines a ventilating duct 23 with an outer mouth 24 and an inner mouth 25.
  • the valve element 26 is pivotable on a pin 27 and can thus be brought from an open position via intermediate positions, one of which is indicated by 26', to a closed position, indicated by 26''.
  • the pivotation can take place with a manually operated mechanism, but will be effected in this embodiment, in accordance with the embodiment shown in Fig. 2, with a motor not shown, and readjustment in an adjusted throughput position so as to keep the passed amount of air constant is effected by a sensor 28 in a controlled manner.
  • valve element may be varied in many ways or adapted to specific conditions.
  • operating mechanisms shown may be mutually exchanged or replaced by another suitable construction.
  • One example may be the motor-driven displacement of the hinge 16 in the embodiment shown in Fig. 3.
  • the housing of the ventilating device may be varied in any desired way and further conventional provisions, such as insect grilles and the like, may be arranged therein.
