  • the measuring system 4 detects at least one characteristic variable for a wave property of the received measuring radiation, such. As the amplitude, frequency, phase or polarization or angle of rotation. Based on the change in the wave property of the received measurement radiation with respect to the transmitted measurement radiation, the characteristic characteristic of the material 200 to be treated is determined. The change relates in particular to the phase and / or the amplitude and / or further characteristic parameters and can be described for example by corresponding scattering parameters.

  • the pulses have correspondingly steep flanks.
  • the receiving devices 24, 240 are designed to receive the broadband pulses. In this case, the receiving devices 24, 240 detect only the measuring radiation, which lies within a certain time window.
  • the time window begins in an adjustable time after the transmission of the transmission pulse. Such a time window makes it possible to determine from which spatial area of the treatment space 3 or the material 200 the received measurement signal originates.
  • the momentum is influenced by the interaction with the item to be treated 200 so that characteristic wave sizes such as the phase or amplitude change.
  • the changes are detected by the measuring system 4 and evaluated by the processing device 5 time-dependent, so that the electrical properties of the material to be treated can be determined in exactly the spatial area from which the received measuring radiation originates.
  • the spatial resolution is greater or smaller. If, for example, the spatial resolution is to be less detailed, one can work with a lower frequency bandwidth or the spatial information is averaged.
  • the FIG. 4 shows a highly schematic representation of another household appliance in a side view.
  • the measuring system here has an ultra-wideband radar device 44, which has pivotable transmitting device 14 and a pivotable receiving device 24. By pivoting, a spatially resolved description of characteristic parameters of the material to be treated 200 is made possible with only one transmitting device 14 and one receiving device 24.
  • the receiving device 24 is preferably pivoted in a spacing grid along the material 200 to be treated.
  • the transmitting device 14 retains its position. At each pivot position of the receiving device 24 measuring radiation is detected over the entire frequency band observed.
  • the receiving device 24 has a time window for the reception of the measuring radiation reflected and transmitted on the material to be treated, which is preferably passed through once completely. Subsequently, the transmitting device 14 is moved, wherein at this new position, the receiving device 24 is pivoted again along the spacing grid.
  • a directional characteristic is used, so that the transmitting device 14 is pivoted when the receiving device 24 receives a signal with a corresponding phase shift.
  • the measurement run described above can also be repeated in a desired time grid in order to observe the temporal behavior of the parameter of the material to be treated 200.

  • the measuring system presented here is equipped with movable receiving devices 24, 240.
  • the transmitting device 14 is pivotable. During a measuring operation, the transmitting device 14 thereby assumes a specific pivoting position, while the receiving devices 24, 240 are moved along the material 200 to be treated. Preferably, the receiving devices 24, 240 are moved along a predetermined distance grid. Other combinations of stationary, movable and / or pivotable transmitting devices 14 or receiving devices are also possible.

  • the heating device 12 has an oscillator device 52 and an amplifier device 62, which together generate and amplify electromagnetic radiation power for heating the cooking chamber 13.
  • the heater 12 is controlled by a controller 42.
  • the measuring system 4 is designed here as an ultra-wideband radar device 44 and has a transmitting device 14, a receiving device 24 and a processing device 5.
  • the measuring system 4 operates substantially similar to that in the FIG. 3
  • the measuring system 4 shown here determines, based on the change in the wave property of the received measuring radiation with respect to the transmitted measuring radiation, a spatial power distribution of electromagnetic radiation. In this case, the power of the measuring radiation absorbed by the treatment space 3 and / or by the material to be treated 200 is determined as a function of the frequency.
  • the measurement system may also include an ultra-wideband radar device 44 or a reflectometer device 54 as previously described.
  • the ultra-short pulses emitted as measuring radiation are preferably in the range of picoseconds to nanoseconds or even microseconds.
  • the frequency bandwidths associated with Fourier transformation are in particular in the range of a few 10 MHz to 1 Hz.
  • the pulse duration is chosen so that the reflected measuring radiation in the treatment chamber 3 is not superimposed on the way to the receiving device 24 with the incoming pulse.
  • the pulse length is selected to be so short that multiple reflections from different regions of the treatment space 3 can be discriminated from reflections at the treatment space 200.
  • the time window is set as described above.
  • cavity resonances Due to the frequency-dependent difference between transmitted and received power of the measuring radiation, cavity resonances appear at certain frequencies. With such cavity resonances, a particularly large amount of radiant power is absorbed by the item to be treated 200 and the treatment space 3. In this case, it is preferably assumed that the treatment area 3, which is usually metallically lined, exhibits a negligible absorption compared to the material 200 to be treated.
  • the cavity resonances are in particular interpreted as describing the field distribution or the spatial distribution of electromagnetic power supply within the treatment space and in particular within the material to be treated 200.
  • the cavity resonances therefore decisively determine the temperature distribution in the material to be treated 200.
  • the cavity resonances thus described by the measuring system 4 can essentially also be transferred to the radiation power supplied by the heating device 12 into the treatment space 3.
  • it can be predicted which cavity resonances will occur with the heater active.

  • the power supply to the material 200 can be influenced in a targeted manner, for. B. by Stirrer or orientation of the material 200.
  • the complex permittivity for each measurement frequency in the frequency band of the ultra-wideband radar device 44 is preferably determined.
  • the absorption, reflection and transmission of electromagnetic radiation power of the respective frequency can be determined.
  • the domestic appliance 1 shown here also has the advantage that the heating device 12 can be controlled in accordance with the previously determined spatial power distribution.
  • the heating device 12 can be controlled in accordance with the previously determined spatial power distribution.
  • radiation power can be generated at the specific frequency or in a specific frequency range.
  • the oscillator device 52 is operatively connected to the control device 42 and controllable by this.
  • the frequency of the radiation power emitted by the heating device can be set as a function of the power distribution or the determined cavity resonances determined by the measuring system.
  • a frequency is chosen for which the item to be treated has previously shown a high or low absorption capacity in the measuring cycle. It is also possible for the heating device 12 to emit radiation power at different frequencies over time so that certain field distributions or cavity resonances can be superimposed in succession over time. With knowledge of the spatial absorption capacity of the material to be treated 200, it is also possible to supply a high radiation power to certain areas of the material to be treated 200 and to administer a correspondingly low radiation power to other areas. For example, food can be heated more in an inner area than in an outer area.
