Definitions

  • the invention relates to an air inlet or outlet, with an air passage opening, which is associated with a closure, which can be brought into an open and a closed position by means of at least one operating element driven by an electrical actuating device.
  • An air inlet or outlet of the type mentioned is known. He has a louvered air passage opening.
  • the lamellar closure can be displaced by means of an actuating device in an open position or in a closed position.
  • the actuating device has a Bimetallaktuator, which is associated with an electrical heating resistor. If the heating resistor is energized, the bimetallic actuator, which moves the lamellae of the lamellar closure from the closed position into the open position, curves with an operating element.
  • the known Lucasein- or -auslass an electric fan is assigned, which promotes air through the open air passage opening. In order to prevent the lamellar shutter from closing again when the fan is running, the bimetallic actuator must be continuously heated.
  • the electrical heating resistor is turned off, causing the Bimetallaktuator cools and returns to its original position, whereby the operating member is displaced and thereby returns the lamellar shutter in the closed position.
  • the known air inlet or outlet has a relatively high electrical energy consumption, since the electrical heating resistor must be operated permanently to keep open the lamella closure.
  • an air inlet or outlet is known, the closure of which is assigned to an air passage opening can be brought into the open or closed position by means of an electric motor and a displacement device driven by the electric motor.
  • This configuration requires a high design effort and leads to correspondingly high costs.
  • the invention has for its object to provide an air inlet or outlet that works energy efficient and has a simple low-cost construction.
  • the fixing device may be a very simple device. So it is sufficient in particular to provide only a rear handle to a stop surface of the closure, so that the latter is fixed in the open position.
  • the arrangement is preferably made such that after the generation of the rear grip, the fixing device for maintaining the fixation requires no electrical energy.
  • the fixing device has its own electric drive for bringing about its fixing position or release position, or is driven directly or indirectly by the actuating device.
  • the own electric drive must be energized only to bring about the fixing position or bringing the release position, so that the energy consumption is negligible.
  • the actuator can be used to drive the fixing device with. It is thus possible, for example, for a crossbar to be displaced by it, which holds the closure in the open position. To bring about the release position, the actuator displaces not only the closure, but also the mentioned latch.
  • an indirect driving is possible, in particular when the branching movement of the shutter energy is diverted to actuate the fixing device.
  • the fixing device is a fixing device operating on the "ballpoint pen principle” or on the “locking principle".
  • a working according to the "ballpoint pen” fixing device is transferred by means of a driven by the electrical actuator component in a detent position - without the supply of energy is required - as long as is maintained until by renewed, taking place by means of the actuator actuation the locking position leave again becomes.
  • a fixing device operating according to the "locking principle” has a displaceable bolt which, in the open position of the closure, creates a rear grip, as a result of which the open position of the closure is fixed. If the closure is to be closed, then it is first necessary to remove the rear grip by bolt displacement. Only for the latch operation requires such a fixing energy, but not in the time in which the latch is in the locked position or Endriegelungs ein.
  • the actuator for opening the shutter and for closing the shutter causes the same movement of the operating member. Consequently, the actuator can be set up very easily, since they always displaced the operating member in the same manner, regardless of whether they should open the closure or close the closure. Accordingly, in the case of the actuator as a bimetallic device provided with heating resistor, it suffices to energize the heating resistor to open the shutter. If this is open, the fixing device ensures that the open position is maintained so that the heating resistor can be switched off.
  • the heating resistor is energized again, whereby the operating member performs the same sequence of movements as in the opening operation, thereby unlocking the preferably acting on the "ballpoint pen" fixing causes and - after switching off the heating resistor - a shift of Closure in the closed position allows.
  • a development of the invention provides for an electronic timing circuit for at least one preferably adjustable default time of the electrical current supply of the actuating device.
  • This is a very simple and inexpensive measure, since the current is independent of the actual time required the opening displacement of the closure is specified.
  • the arrangement is preferably to be made such that the adjustable default time of the energization of the actuator is greater than the time required for the opening displacement of the closure.
  • the closure has at least one air flap, in particular a plurality of louvers designed as louvers. If several slats are present, this is called a slat closure.
  • the actuator causes a linear actuation of the actuator, whereby a simple construction is given.
  • the actuating device has at least one Bimetallaktuator with at least one electric heating element, at least one electromagnetic actuator or at least one electric linear drive.
  • the Bimetallaktuator with at least one electric heating element has already been discussed above.
  • an electromagnetic actuator it may, for example, be an electrical coil with whose electromagnetic field an armature can be displaced in order to open or close the shutter.
  • an electric linear drive can also cause a closure opening or closing.
  • a development of the invention provides an electronic control circuit which has at least one sensor for detecting the position of the closure.
  • the sensor allows the detection of the current position of the shutter, so its closed position, open position and / or the detection of at least one intermediate position, so that in certain operating situations or special situations (for example, in case of electrical power failure) can always be a safe operation management of Luftein- or -auslasses.
  • the air inlet or outlet is formed with at least one electric fan. If the fan is put into operation, the shutter opens, allowing air to be conveyed through the air passage opening. If the fan is turned off, so also closes the shutter, ie, the air passage opening is closed.
  • the invention further relates to a method for actuating a closure of a Lucasein- or -auslasses, in particular according to one or more of the preceding embodiment (s), wherein the closure by means of at least one driven by an electric actuator operating member in an open and a closed position displaced is, wherein the following steps are provided for bringing about the open position of the closure: electrical energization of the actuator for driving the operating member to shift the shutter in the open position, the actuator and the operating member separately successful fixing the open position of the shutter and off the energization of the actuator.
  • the fixing which takes place separately for the actuating device and the operating element means that there are independent means for fixing which are not serve the displacement of the closure or the operating member.
  • a development of the method provides that the operating member is moved to open the shutter from a rest position in a Verlagerungsend too and that after fixing the open position of the shutter, the operating member is moved back from the actuator to the rest position in particular energization free.
  • This return movement is preferably given when the actuator has the at least one Bimetallaktuator with the at least one electric heating element, as by cooling the Bimetallaktuators this on the one hand energization-free and on the other hand returns to its normal position, so returns the control member in the rest position.
  • the operating member by the actuating device for closing the closure from the rest position in the Verlagerungsend too and after the cancellation of the fixation of the closure back to the rest position and under transfer of the closure in the closed position, in particular energization free is moved.
  • This process is preferably given when a fixing device is used, which operates on the "pen principle".
  • the actuating device is electrically energized for bringing about the open position and the closed position of the closure for a predetermined time. This time is preselected and preferably independent of the time required for the movement of the shutter in the open position or in the closed position. Finally, it is advantageous if the respective position of the closure is sensed and an electrical control circuit the sensed closure position is transmitted. As a result, there is a query possibility for the control circuit, ie, it can take into account the respectively determined closure position in its operational management.
