Definitions

  • the invention relates to a masonry dehumidifying device with a coil, which emits high-frequency electromagnetic fields, the coil Oscillator is connected upstream, through which a high-frequency AC voltage is generated with which the coil is applied.
  • WO-A-94/20702 shows such a masonry dehumidifying device.
  • a converter is arranged downstream of the oscillator, to which the oscillation generated by the oscillator is supplied as external energy and the electromagnetic impulses supplied to it in one converts gravomagnetic standing wave that is emitted via the coil.
  • EP-A-395 085 shows a masonry dehumidifying device in which one high-frequency vibration of about 141 kHz by exciting a coil and a capacitor comprising a resonator by a low frequency Pulse sequence signal is generated. After each excitation of the resonator one occurs here high-frequency, damped vibration, its amplitude during the duration half a period of the pulse train signal to a value below 10% the maximum amplitude of the vibration drops. Since here the frequency of high frequency waves emitted from the coil from the parameters of the coil and of the capacitor within the resonator is an adjustment required, which is cumbersome and difficult. There is also a risk that Metal parts etc. in the vicinity of the coil, as well as changes of air pressure and humidity to disturb the radiated electromagnetic field. The same applies to damping the vibration.
  • the oscillator Modulator is connected by the sequences of wave trains an envelope of lower frequencies than the high-frequency ones Vibrations are generated, the envelope curve by a on the input side to a low-frequency square-wave AC voltage connected differentiator is generated.
  • the frequency is the high-frequency alternating fields can be determined very precisely. Influencing the High frequency of the alternating field or changes in the curve shape Due to environmental influences in the area of the coil, such as electrical conductive metal parts are clear in the device according to the invention decreased. A comparison of the device during commissioning is therefore not possible required.
  • the combination of high frequency, electromagnetic Vibrations with low-frequency vibrations, which are preferably in Range of the fluctuation frequency of the earth's magnetic field of 7-15 Hz can also result in a particularly good dehumidification effect, since the Moisture molecules are pushed again and again effectively become.
  • the drawing shows a block diagram of a Masonry dehumidifying device according to the invention.
  • the electronic circuit on which the drawing is based generates a high-frequency voltage U, which is applied to a coil L, which a generated alternating electromagnetic field E, which on a from the coil L distant wall 1 acts, which is thereby dehumidified.
  • the circuit shown is powered by a power supply unit 2 and applied with a low-frequency signal S1, which as Reference signal for phase comparison 3 is used.
  • VCO voltage-controll-oscillator
  • the VCO generates an extremely frequency stable output signal S3 with preferably 141 kHz as precise as possible.
  • the coil L With this high-frequency signal S3, the coil L applied, which generates a corresponding electromagnetic alternating field.
  • the signal S3 is forwarded to a frequency divider 4, which the high-frequency signal, for example by a digital counter circuit with a Frequency division factor converted into a low-frequency signal S4.
  • the high-frequency signal S3 of 141 kHz at one through the wiring of a digital counter achieved a frequency division factor of 1/1410 low-frequency signal S4 generated.
  • the phase comparison 3 with this signal S4 and the signal S1 is here also has 100 Hz, performed and the result of the phase comparison is used as signal S3 to control the VCO 6.
  • the oscillator 5 thus comprises a phase comparison 3, a VCO 6 and also a frequency divider 4 for generating a signal of the same Frequency as the reference frequency.
  • the components phase comparison and VCO of the oscillator can be implemented on a standard module, for example.
  • This signal S5 is used to modulate the high-frequency signal S3 in Modulator 7 used, so that there is a signal S6, the high frequency Vibrations with envelopes inform the exponential decay here Has individual pulses S5.
  • This signal S6 is applied to the coil L. The modulation of the high-frequency signal with sequences of exponential declining single-wave trains results in a compared to the high-frequency Continuous signal better dehumidifying effect and better electromagnetic Compatibility.
  • the air coil L additionally with a low-frequency signal, here one through one Frequency divider 8 generated signal of 50 Hz via a switch 10 additionally be charged.
