Definitions

  • the invention relates to a ventilation device for the supply or removal of air in or from preferably forced ventilation rooms, with a controlled fan or .
  • the rooms can in particular be windowless rooms in buildings.
  • the invention is therefore based on the object to design a ventilation device so that a faster and problem-free installation is largely possible regardless of installation work at the installation site.
  • control is carried out by a photoelectric control unit.
  • the photoelectric sensor switches the fan on when the light falls.
  • the electrical connection of the ventilation units is limited to the simple connection to the electrical network, for example to junction boxes or junction boxes.
  • Other installation work e.g. B. external wiring in switch boxes on the light switch and additional switch boxes for accommodating adjustable follow-up relays are not required. Transmission errors between the architect, electrician and ventilation company are also avoided. The situation regarding complaints and guarantee cases is considerably simplified. All legal and ventilation requirements can also be easily met.
  • the electrical supply line to the ventilation unit no longer has to be routed via a switch arranged at a distance from the ventilation unit, in particular no longer via the room lighting switch, so that the voltage supply can be routed directly to the fan from the next junction box or the like.
  • control unit and thus all the necessary switching devices for the ventilation unit can also be integrated in the fan housing, as a result of which the ventilation unit can form a structural unit as a compact unit, which only has to be installed on the ventilation side and electrical supply voltage required.
  • the control unit can also be mounted directly on the fan housing.
  • the invention enables the fan of the ventilation device to be switched on and off in a simple, reliable and cost-effective manner.
  • a preferred field of application of the invention is the ventilation of windowless rooms of buildings or the like, in particular of sanitary rooms, such as toilets, bathrooms or the like, which have a ventilation device for ventilating the room by the control unit as a result of the room lighting being switched on whose light is switched on automatically and is automatically switched off again by switching off in the wake of the extinction of the light.
  • the ventilation unit can be switched off immediately as the room lighting goes out, or it can also be provided that this ventilation unit is switched off with a follow-up time of, for example, 5 to 20 minutes. he follows. This also eliminates a follow-up switch arranged at a distance from the ventilation unit, since the follow-up switch, if it is to be provided, can be arranged on the ventilation unit itself, preferably can be integrated into the control unit.
  • the control unit can also serve to control it. If the room in question is only ventilated by opening and closing a ventilation flap, so that this ventilation device has no fan, then the control unit can only serve this ventilation flap and is in or on it Housing arranged.
  • ventilation devices consisting only of ventilation flaps are, for example, often arranged on or in passages leading from the relevant rooms into a central ventilation duct, wherein a roof fan or the like can be connected to the central ventilation duct.
  • a ventilation device is shown in simplified form, in which a fan 1 is housed in a housing 2.
  • the housing 2 is designed here for the wall structure, but it can also be designed as a section of a pipe or as a built-in housing, which can be arranged partially “under plaster”.
  • a photoelectric control unit 3 is arranged on the housing 2, the photosensitive sensor (sensor) of which faces the light source (lamp) of the room to be ventilated and which is used to switch the fan 1 on and off.
  • control unit can have a circuit breaker controlled by its photosensitive sensor, which switches on the fan in the wake of the lighting of the room lighting and, when the room lighting is switched off, is switched off again by means of the photosensitive sensor due to the darkness again entering the room.
  • the fan can also be switched off with a time delay, i. H. with follow-up time.
  • a time delay i. H. with follow-up time.
  • FIG. 2 An exemplary embodiment of a circuit arrangement suitable for this is shown in FIG. 2.
  • the fan motor 14 is connected to a mains line with the phase connections 11, 12 and the protective conductor 13.
  • the drive 14 can be switched on by a circuit breaker 15.
  • the circuit breaker 15 is part of a circuit arrangement 16.
  • the circuit arrangement 16 is also fed from the network 11, 12.
  • the power supply of the circuit arrangement 16 is si by a power supply unit with the rectifier made.
  • the circuit arrangement 16 comprises a photoelectric switch 18, which contains a light-sensitive input stage, preferably a photodiode 19, and an output switch 21, preferably a switching transistor.
  • An integrating stage 22 is connected to the output switch 21, which in the simplest case is realized by connecting a resistor 23 and a capacitor 24 in parallel.
  • a threshold value stage 25 is expediently located parallel to the integrating stage 22. It is advisable to hit the input resistance of the threshold value stage 25 as high as possible, for example with the aid of a field effect transistor.
  • the input of the circuit breaker 15 is connected to the output of the threshold value stage 25.
  • the circuit breaker 15 itself comprises, for example, a relay 26 and a make contact 27.
  • the relay 26 and the make contact 27 can of course be replaced by a power transistor or a thyristor.
  • FIG. 3 shows an advantageous construction of the ventilation device with the circuit arrangement 16 of the control unit 3.
  • Both the drive 14 and the circuit arrangement 16 are installed in the housing 28 of the fan 30.
  • the housing 28 is partially made of translucent material. The light that is then still sufficiently incident through the wall of the housing 28 is controlled by the photodiode 19 of the circuit arrangement 16. As a result, the circuit arrangement 16 is very well protected against damaging environmental influences.
  • the photodiode 19 is excited by its light when the room lighting is switched on and closes the output switch 21. This causes the threshold to be exceeded value switch 25 - the relay 26 in the circuit breaker 15 controlled. The relay 26 picks up and closes the switch 27. As a result, the motor 14 serving as the drive starts. This state remains as long as the room lighting is switched on. If the room lighting goes out again, the photodiode 19 is de-energized and the output switch 21 is thereby opened. However, the capacitor 24, which was previously charged when the output switch 21 was closed, can discharge only very slowly, specifically via the resistor 23 connected in parallel.
  • the discharge time can be determined with the value of the resistor 23 and the capacitance of the capacitor 24. Because the capacitor 24 discharges very slowly, the relay 26 - via the threshold switch 25 - is supplied with sufficient control power for a certain time, so the relay 26 remains energized and the switch 27 is closed, so the motor 14 continues to run.
  • the threshold switch 25 is therefore useful in order to create clear control conditions for the relay 26. If the potential at the capacitor 24 has dropped below a minimum value, the threshold switch 25 switches over, the relay 26 drops out, the switch 27 is opened, and the motor 14 comes to a standstill.
  • the voltage of the RC element 23, 24 forming an integrating stage 22 is reduced in order to achieve the lag time.
  • Other designs of the integration stage are also possible, for example as a Miller integrator.
  • the lag time can be set differently with it.
  • Ventilation devices to which the invention relates, are in particular those in wall mounting or wall mounting, so z.
  • the photosensitive sensor can be of any suitable type, for example a photo resistor.
