Definitions
- the invention relates to a ventilation device for the supply or removal of air into or from preferably forced-ventilated, windowless rooms, with a controlled fan.
- the invention also relates to a ventilation device for windowless rooms, which has a ventilation flap that can be controlled by a control unit.
- a controlled fan serving to ventilate interior rooms, such as bathrooms or toilets, is known and can therefore be intended in particular for windowless rooms.
- CH-A-612 260 serving to ventilate interior rooms, such as bathrooms or toilets, is known and can therefore be intended in particular for windowless rooms.
- this run-on relay does not serve to switch it on and to switch on the fan, since it only serves to delay the switch-off of the ventilation mode, so that even after leaving the room in question, it can be vented for the period of time determined by the run-on time of the run-on relay and only then shut down the fan .
- a temperature-sensitive threshold switch is also known, which is used to switch on and off a cooling water cooling fan depending on the cooling water temperature of a motor vehicle.
- a light-sensitive threshold switch is also described without reference to a fan, which has a certain type. However, there is no indication of any area of application for this light-sensitive threshold switch.
- the invention has for its object to design a ventilation device of the type mentioned in the preamble of claim 1 or claim 2 so that a quick and easy installation with the least possible electrical installation work is possible.
- a ventilation device for the supply or removal of air into or from preferably forced-ventilated, windowless rooms with a controlled fan in that the fan is controlled by a photoelectric control unit arranged in or on the fan housing, which is arranged responsive to the light of the room lighting of the windowless room.
- the solution according to the invention provides for the above object that the control unit is a photoelectric control unit which is arranged in or on the housing of the ventilation flap and which operates on the Light the room lighting of the windowless room is arranged responsive.
- This ventilation flap is opened to ventilate or vent the windowless room in question, which takes place by means of the photoelectric control unit arranged on its housing whenever the light of the room lighting is switched on when entering the room.
- Such ventilation devices consisting only of ventilation flaps are often, for example, often arranged on or in passages leading from the rooms in question into a central ventilation duct, it being possible for a roof fan or the like to be connected to the central ventilation duct.
- the ventilation device has a fan, this can be assigned a ventilation flap, which can also be controlled by the control unit.
- the invention limits the electrical connection of the concern in new buildings the ventilation unit for easy connection to the electrical network, for example to junction boxes or to 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 therefore no longer has to be routed via a switch arranged at a distance from the ventilation unit, in particular no longer via the switch of the room lighting, so that the voltage supply is directly from the next junction box, the next junction box or the like directly to the ventilation unit can be relocated. This also makes retrofitting the ventilation unit easier, since then the damage to walls, tiles and wallpaper previously unavoidable when retrofitted is kept as low as possible or completely avoided.
- a preferred field of application of the invention is the ventilation of sanitary rooms, such as toilets, bathrooms or the like, which require a ventilation device to ventilate the room.
- this ventilation device is then automatically switched on by its light in the wake of the room lighting being switched on and automatically switched off again by switching off this room lighting in the wake of the light being extinguished.
- the ventilation unit can be switched off directly in the wake of the room lighting or, according to a further development of the invention, it can also be provided that the control unit also controls a circuit arrangement for extending the respective operating time, which is preferably integrated into it.
- the extension of the operating time can be, for example, 5 to 20 minutes.
- the ventilation device has a ventilation flap
- this can preferably be a pivoting flap having a closure flap, since this further simplifies the installation work at the installation site due to its short overall length.
- the design of the ventilation device according to claim 9 is particularly advantageous, since the arrangement of the control unit behind a transparent housing wall section of the housing means that the latter is arranged in a particularly well-protected manner and the external dimensions of the housing are not enlarged.
- the measure according to claim 11, according to which the control unit forms a complete device, has the advantage of being easy to assemble with the ventilation device.
- the ventilation device forms a compact device together with the control unit and thus together with all the necessary switching devices for the ventilation device.
- 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 partially “plastered”.
- 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 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 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.
- the power supply of the circuit arrangement 16 is ensured by a power supply unit with the rectifier 17.
- 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 expedient 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. With the output of threshold level 25 is the input the circuit breaker 15 connected.
- 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 a translucent material. The light that is then still sufficiently incident through the wall of the housing 28 controls 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.
- the relay 26 in the circuit breaker 15 is activated via the threshold switch 25.
- the relay 26 picks up and closes the switch 27.
- 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.
- 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.
