Definitions

  • the invention relates to a ventilation device, in particular an extractor hood, according to the preamble of claim 1.
  • Hoods which have a transmitter and a receiver, the transmitter emitting radiation that is registered by the receiver.
  • the radiation received by the receiver is used to control a fan of the hood that the difference between the emitted radiation and the received radiation component is interpreted as a measure of the amount of exhaust gases in the exhaust air stream.
  • the power supply to the fan is controlled.
  • the EP 0 443 141 B1 describes an extractor hood with a UItraschallsender and an ultrasonic sensor, in which the signal recorded by the ultrasonic sensors signal fluctuations for the control of a fan level are based.
  • a disadvantage here is considered that the ultrasonic sensor is expensive and therefore the appli cation only in extractor hoods of the upper price segment comes into question.
  • the US 6170480 A1 describes an extractor hood with a light path, which is formed by a laser beam. This can be detected, for example, in the IR range, smoke and activated depending on the hood or be set more. Furthermore, temperature sensors or the like may be provided.
  • the US 3723746 A1 describes a device for detecting fire by means of a double light path.
  • a laser is advantageously used. It can be detected how a laser beam is diffracted by increasing the temperature in the air it traverses more or less. A corresponding deviation can then be used as an indication of too high a temperature.
  • the invention has for its object to provide a ventilation device of the type mentioned, with the disadvantages of the prior art can be avoided and in particular a low-cost and reliable way to detect a cooking process and the associated air pollution such as cooking hobs or Air movements over a cooktop is possible.
  • the transmitting device is designed to emit a laser beam.
  • the use of a laser beam has proven to be advantageous both economically and technically.
  • a clearly defined intensity relative to the cross-sectional area of the laser beam can be achieved. This makes it possible to realize even longer measurement distances within the fan, without a reasonable evaluation is difficult due to a too wide expansion of the light cone.
  • the good recognizability of air streaks and air movements in the ventilation device according to the invention is particularly advantageous because it compared with a particle detection operation of the ventilation device can be initiated earlier or adjusted. If the occurrence of particles triggers the operation, there is a high risk that air pollution or cooking spills have already developed and escaped, so that they are no longer detected by the ventilation unit.
  • a laser beam offers particular advantages, since the frequency of the laser beam is largely uniform, so that receiving devices can be used that are particularly adapted to the specific laser frequency or a narrow frequency range. It is thereby achieved that ambient light, which usually occurs in a wide frequency spectrum, does not lead to misinterpretations by a control device or a control circuit.
  • the use of a laser beam also allows long and multiple redirected measuring sections, which allows a particularly fine-meshed detection of air pollution. From an economic point of view, the use of a laser beam is very advantageous. Laser modules today are mass products and therefore very reliable and are also available at low cost.
  • the signal generated by the receiving device with respect to electrical characteristics depends on the power or intensity of the received radiation.
  • Corresponding sensors and receiving modules which generate corresponding electrical signals as a function of light irradiation are known today.
  • a control device with a microcontroller
  • a receiving device can be used, whose output signal with respect to the voltage depends on the incident light.
  • This signal is connected to an A / D converter input of the microcontroller and is thus processed by him. It may also be expedient to use a sensor whose frequency depends on the power of the received radiation, since no A / D converter is required for such a frequency measurement.
  • the signal generated by the receiving device depends only on the incident radiation in a frequency range which largely corresponds to the frequency range of the laser beam.
  • a frequency range which largely corresponds to the frequency range of the laser beam.
  • interference by ambient light or, for example, a built-in an extractor hood lighting are avoided.
  • Technically feasible is the restriction to such a frequency range, for example by means of a filter which is arranged in front of a sensor in the receiving device or by means of special sensors, which are designed for an exclusive reception of light in the corresponding frequency range.
  • the receiving device has a photoelectric sensor, which preferably has a photosensor or a photodiode.
  • a photoelectric sensor which preferably has a photosensor or a photodiode.
  • the receiving device is equipped with filter means which limit the angular range in which incident light is registered by the receiving device.
  • filter means which limit the angular range in which incident light is registered by the receiving device.
  • the drive can be activated and deactivated by the control circuit or the control unit and can be controlled with respect to its power, preferably continuously.
  • the control unit can be designed so that it fully automatically activates the drive for generating the air flow, if a corresponding need has been registered, and also adapts the required power accordingly.
  • a stepless control of the power allows a particularly needs-based operation.
  • it is advantageous in controlling the power at various discrete stages that such control is simpler and less expensive.
  • the control circuit or the control unit for evaluating the signal generated by the receiving device with respect to air streaks or air movements with different density gradients in the measuring section is formed.
  • the control unit is designed in such a way that it interprets lower attenuation in such a way that air streaks are detected on the measuring section. To what extent the damping is due to streaks of air, can be concluded from other parameters such as the oscillation frequency.
  • One for the evaluation of the signal with regard to air streaks or Heilbegung trained control unit activates a ventilation device in principle even at lower attenuation and thus allows in particular in a period of time at the beginning or even before the Heilverunrei ments a very convenient ventilation control.
  • the ventilation device is adjustable with regard to its behavior in order to be operated in the right situation and to the correct extent depending on varying environmental situations, for example use above hotplates or gas flames.
  • the control circuit or the control device for controlling the drive is designed as a function of the intensity or registered power registered by the receiving device.
  • the power is compared for this purpose with the output by the transmitter power or intensity or egg ner set target power or target intensity, with a reduction as an indication of absorption, refraction and / or diffraction due to cooking turf or air streaks or Air movement is interpreted.
  • the controller can be designed so that a reduced registered power is interpreted as an increased degree of contamination of the air, for example by cooking turf, and as a result the power of the drive is increased.
  • the control circuit or the control device for controlling the drive is formed as a function of the intensity or power registered by the receiving device over time.
  • the use of the first derivative of power over time is superior to pure ventilation control based on registered power. Rapid changes in performance are due to turbulence in general or boiling in the area of the measuring section and are indicative of a high concentration of air contaminants such as cooking torrents or air movements.
  • a control of the drive depending on the change the registered intensity or the registered power can also be combined with an evaluation of the intensity or the performance itself.
  • both frequency and amplitude of the power curve over time are used to analyze the impurities on the measuring section.
  • the inclusion of the change in power over time leads to a particularly well-demand-oriented control of the drive.
  • Such a control based on the frequency of the power fluctuations can be realized, for example, by counting the number of intensity maxima or minima in a time segment of defined length and controlling the ventilation on the basis of the value determined thereby.
  • a strong oscillation can be interpreted as a normal cooking operation or gradual termination of the cooking operation, depending on the degree of damping, so that the fan is expediently placed in a main use stage or in a residual suction stage.
  • the transmitting device for emitting a laser beam is formed, the Leuchtpun kt in the receiving device has areas of very different intensity, preferably in the form of an interference pattern.
  • maxima and minima can alternate, in particular generated by interference.
  • Such a luminous spot can be registered by the receiving device not only with regard to whether the luminous spot strikes the receiving device or the sensor.
  • a shift of the luminous spot on the photodiode leads to a characteristic of air streaks and particles in the measuring section result, without that the luminous point would have to be deflected so far that he leaves the photodiode.
  • the particularly advantageous evaluation Interference patterns can be achieved by using a laser with a comparatively wide frequency spectrum. Although it may be desirable for other aspects of the invention to use a laser with a particularly narrow frequency spectrum, it may therefore also be advantageous, depending on the requirements, to use, for example, a multimode laser diode with a broad frequency spectrum.
  • the transmitting device and the receiving device are designed such that the receiving device always lies within the luminous point during operation.
  • the receiving device not the luminous spot descending from the receiving device or the photodiode is intended to influence the output signal of the receiving device, but the movement of the luminous spot via the receiving device.
  • the maxima and the minima of the interference image of the luminous point move across the sensor.
  • the size of the sensor should be chosen so that it is smaller than the extension of the maxima and minima, which can also be influenced by optical aids such as lenses.
  • the registration of the movement of the luminous spot via the receiving device can take place, for example, by evaluating a moving interference pattern with maxima and minima.
  • This can advantageously be used for control of the extractor hood with a corresponding control method which carries out an evaluation of the output values of the sensor in the event of an interference pattern moving over it.
  • the transmitting device and receiving device are designed such that the diameter of the luminous point a few mm wider than the receiving device, preferably at least 5 to 8 mm wider.
  • the transmitting and receiving device are designed such that the diameter of the luminous point a few mm wider than the receiving device, preferably at least 5 to 8 mm wider.
  • a particularly low susceptibility is achieved.
  • In the field of ventilation devices often find large manufacturing tolerances application. Due to the fact that the mode of operation of the transmitting and receiving device according to this development does not depend on the transmitting and receiving devices being at their desired position to the nearest millimeter, more favorable production methods can be used and no additional measures are required to obtain the correct one and to ensure highly accurate alignment of these facilities.
  • the control circuit or the control unit evaluate the output signal with regard to signal frequency and signal attenuation. This is particularly useful when using a laser beam that is so pronounced that it always rests on the receiving element in normal operation, and has a luminous point with areas of greatly varying intensity.
  • the registered intensity or the determined attenuation of the laser beam can be regarded as an indicator of the presence of steam and the frequency as an indicator of the presence of heat.
  • these parameters are well suited to assess the nature of the cooking process taking place under the ventilation device and to generate a correspondingly adapted airflow.
  • a strong damping can be seen as a sign of intensive cooking operation and a high signal frequency as a sign of intensive frying operation.
  • the transmitting device and the receiving device are arranged opposite each other on both sides of the air flow in the ventilation unit and the transmitting device radiates in the direction of the receiving device.
  • the transmitting device and the receiving device are preferably on opposite sides Arranged sides of the air flow, in particular centrally above the cooktop, so that the measuring section thwarts the air flow.
  • Such an arrangement with direct alignment of transmitting and receiving device to each other is simple and less prone to interference.
  • the transmitting device and the receiving device are arranged so that a laser beam emitted by the transmitting device passes from the at least one reflecting device to the receiving device.
  • a reflection device allows the arrangement of transmitting and receiving device in the immediate vicinity of each other by sending and receiving device are arranged on one side of the fan. On the opposite side of the reflection device is arranged. In this way, it is also possible to form the transmitting and receiving device as a module, whereby the assembly and adjustment effort compared to the use of two separate modules is significantly reduced.
  • At least two reflection devices are provided which are arranged and aligned such that a laser beam emanating from the transmission device passes at least twice reflected by at least one reflection device to the reception device.
  • the two reflection devices face each other and are arranged parallel to one another. It is thus possible to allow the laser beam to be reflected several times by both reflection devices.
  • the reflection means may e.g. be arranged on the front and rear or on the left and right inside of the ventilation unit or the hood. By appropriately arranged and aligned transmitting and receiving devices, it is possible to allow the laser beam reflect so many times from one side to the other and thus to lay almost the entire cross-section of the ventilation device for subsequent evaluation by the control unit or the control circuit.
  • the transmitting device has a laser diode for emitting the laser beam, in particular a multi-mode laser diode.
  • Multimode laser diodes emit light of different frequencies and, for technical reasons, are well suited for the proposed ventilation devices.
  • the beam emitted by them has increased divergence and increased diffraction tendency due to increased wavelength dispersion compared to singlemode laser diodes.
  • due to their frequency spectrum they generate an interference pattern in the luminous spot, which, as described above, enables a particularly good evaluation with maxima and minima with low susceptibility to interference.
  • the increased divergence and the interference pattern are particularly advantageous in the detection of air streaks.
  • Particularly suitable for a good readability is a dot diameter of 5 mm to 15 mm, in particular 10 mm.
  • Sharp focusing of the laser beam can be disadvantageous for air streak detection.
  • the transmitting device has a collimator lens.
  • This collimator lens allows the adaptation of the position of their focal point a convenient optimization of the transmitting device.
  • the widening of the laser beam in the region of the receiving device can be varied by means of the position of the collimator lens and / or the focal point of the collimator lens.
  • the laser beam can also be made slightly divergent. An increased expansion increases the sensitivity of the receiving device, in particular with regard to air movements, so that the control unit is supplied with a signal that can be interpreted more easily.
  • the controller accordingly controls the fan very needs, especially even before steam.
  • an expansion of the laser beam also leads to a lower light output received by the receiving device.
  • the divergence of the laser beam from the control unit or the control circuit is adjustable. Since the attenuation of laser beams of lesser divergence by air streaks is less than the attenuation of laser beams of high divergence, can be achieved by adjustability of the divergence that can be differentiated particularly reliably between attenuations due to vapors or particles on the one hand and air streaks or air movements.
  • the control unit of such a ventilation device can therefore measure, for example, alternately the damping at high and low divergence and set in the case of a low attenuation, which is due only to air streaks, the fan in operation.
  • the adjustability is preferably achieved via an adjustable lens.
  • At least two transmitting devices are provided for emitting laser beams of different divergence.
  • two transmitting devices can be achieved with different divergence setting that the cause of attenuation on the measuring section is reliably detected.
  • the adjustability and the resulting increased complexity of the transmitting device can thereby be avoided.
  • both transmitting devices are directed to only one receiving device, which measures the incoming power of the laser beams either simultaneously or alternately.

  • a filter mat 19 and a fan 20 are arranged, which sucks the kitchen vapors through the filter mat 19 in the upper part 18.
  • a transmitting device 22 with laser and a receiving device 24 are arranged on the right and left inside. The transmitting device 22 is aligned in such a way that a laser beam 25 emanating from it is directed directly onto the receiving device 24.
  • cooking hobs rise from the cooking zones 14 of the cooking hob 12, they reach the lower part 16 of the extractor hood 10.
  • the laser beam 25, which is permanently or periodically activated, is partially absorbed by these cooking hobs and partially diffracted and broken. This results in a reduced input power at the receiving device 24 compared to the output power.
  • a signal generated by the receiving device 24 is fed to a control unit, which on the basis of the power difference between the output power of the transmitting device 22 and input power of the receiving device 24 and based on the time change of this power difference conclusions about the degree of air movement and the presence and the amount allows cooking hobs.

  • the diameter of the laser light spots 90, the through the interference image and the Fresnel lens according to FIG. 9 are generated in front of the receiver, much larger than the photoelectric sensor 92.
  • the FIGS. 11 and 12 show only a small portion of the luminous point 90. This is generated by a laser diode with a comparatively wide frequency spectrum, resulting in an interference pattern with maxima 94 and minima 96.
  • This interference pattern is shown here as relatively irregular, which is usually the case in practice because of not optimal formation of the Fresnel lens and the other optical path. Irrespective of the actual size of the maxima 94, it is important to have the concrete distance from one another, ie the size of the minima 96.
  • the speed of the luminous point 90 and thus of the maxima 94 is relatively large and these cover the sensor essentially completely or not at all when moving, the peaks are easy to distinguish or to recognize. Since each maximum 94 has space around it or the minima 96 are in between, it is also ensured that after every passing of a maximum 94 via the sensor 92, no light is registered in the minimum. So a good distinction is achieved. It is therefore important in general that the maxima 94 are approximately as large in terms of their area like the sensor 92, advantageously two to four times as large. This ratio can be influenced by the maxima 94 or the sensor. The luminous point 90 in turn is many times larger. He should always cover the sensor 92.
  • FIG. 10 is shown over time, as the individual peaks as individual rashes in the overall course represent a kind of noise. However, it is still easy to recognize or optically evaluate via the sensor 92 and electronically via the controller. It should be noted that in FIG. 10 the attenuation a is shown over the time t or over the time course of the cooking process. The actual intensity of the measured maxima 94 on the sensor 92 is, so to speak, the reciprocal of the attenuation. The change in the frequency of oscillating or moving the maxima is difficult to recognize, only in connection with FIG. 13 ,
  • FIG. 13 the signal behavior is shown at different states, which correspond to the different processes during the cooking process.
  • field I and at the beginning of the cooking process at FIG. 10 Damping A and Oscillation f are low, because not much is happening in the range of the extractor hood or over a hotplate 14 according to FIG. 2 .
  • field II the damping is low but the oscillation still medium, so that there is still a lot of heat here with little steam. This indicates the end of a cooking process.
  • field III the attenuation is moderate, but the oscillation is low. This suggests in the conclusion rather on the beginning of a cooking process.
  • box IV damping and oscillation are medium in size, so that a normal cooking process can be concluded. In particular, only one hotplate is operated here.
