  • a cooking device according to the invention has at least one of those described above Devices on.
  • the output of the cooking vessel Controlled cooking zone. This requires the temperature to measure in the cooking vessel.

  • a method and a device are described below, to in the bottom of an on an induction cooking zone K standing cooking vessel or cooking appliance 8 temperatures T or temperature changes to measure and control information to use the power P of the induction cooking zone K, so that automatic Cooking functions are possible.
  • the resonant circuit of the induction heating system according to FIG. 1 exists from an inverter 5 and an induction coil 6, the under a surface carrying a cooking appliance or cookware 8 9, for example a glass ceramic plate, is arranged.
  • the bottom of the dishes 8 is ferromagnetic. In it is caused by eddy currents caused by the magnetic field of the induction coil 6 induced, heat generated.
  • This impedance Z is influenced by the Temperature T in the bottom of the dishes, especially due to changes the electromagnetic properties of the soil material. It in turn influences the oscillation frequency f des Inverter 5, which finally for measuring the temperature T is used in the bottom of the dishes.
  • the coil current I is measured by means of a current transformer 7.
  • Fig. 2 shows its basic appearance.
  • the oscillation frequency f (20 to 60 kHz) is used with the rectified mains power supply modulated. This signal leads to a frequency measurement circuit 3, which analyzes the signal and which Vibration frequency f determined.
  • the size of the mains voltage supply is measured by a voltage measurement circuit 10 and passed the information to a control logic 2.
  • the Control logic contains control algorithms A and ensures filtering of the signal if it is noisy.
  • the algorithm A calculates the appropriate power P for the cooking zone K to the desired Ensure functionality based on the information about the frequency f, the voltage supply U and the User settings entered via user interface N (Fig. 3).
  • the operating frequency of the induction inverter 5 moves depends in particular in the range between 20 and 60 kHz from performance level.
  • the frequency f i.e., the inversion of the Period of a cycle
  • the rectified Sinusoidal period i.e., over a period of 10 ms
  • the frequency is measured when the Mains voltage has its maximum.
  • a timer with a delay time of 5 ms in the zero crossing of the mains voltage is triggered, the frequency measurement is triggered after the delay time has elapsed out. 2 is the triggering of the timing circuit marked with ZT and the triggering of the frequency measurement with FM, the time delay signal with ZV.
  • the signal of the Current converter 7 is scanned with an A / D converter and in stored in memory (500 samples in one interval of 666 ns gives 25-75 samples per period). Of that the period of the vibrations (6-20, depending on the frequency) calculated and the center frequency. influences the frequency due to changes in the mains power supply (by the mains power supply device 4) by measuring the voltage (by the voltage measuring device 10) and offsetting with empirically determined values or formulas Getting corrected. The corrected and / or uncorrected Frequency is then used in the algorithms to measure temperatures to signal.
  • a calibration curve f (T) must be recorded or to register. This is done by measuring the temperature T im Crockery bottom (using separate temperature sensors) and simultaneous registration of temperature T and frequency f with a fixed power setting P. Leave the measurement data then with a curve fitting method, for example one Polynomial fit, fit to an accepted accuracy. At the end of this section we get a relationship f (T) for a certain tableware. However, since the frequency f depends on the performance level P depends, all of this is for the others to use Repeat performance levels to eventually build a relationship f (T, P) to have that in the control logic as a calibration curve (for a specific dish) is saved.
  • FIG. 4 shows a family of declining f (T) calibration curves for Services P1, P2, P3 and P4.
  • control logic connects the measured frequency f with a temperature T for a certain power level P. This then makes it possible to perform the desired functions accordingly perform the algorithms stored in the control logic.
  • Value f-rel for 250 ° C at approximately 0.83 for a wide register from pans to the user when using this method can be recommended.
  • control algorithms A are described below.
  • the control algorithm A monitors the change of the frequency response f (t) over time t (FIG. 5). If the first derivative f '(t) from a negative value to about Changed to zero, the bottom of the pot has a constant temperature reached so that the time t at which the food is cooked boils or boils, can be derived. In this case the Power P or the current I in the induction coil 6 to one predetermined value reduced. Notwithstanding this, Fig.
  • a drop occurs during the empty or dry cooking (FIG. 6) the frequency f when, for example, water from the pot has escaped. This can occur as a sudden drop or one sudden change in the first derivative f '(t) or as a certain one Value of the first derivative f '(t) can be recognized accordingly a rise in temperature in an empty pot. For slow dry cooking processes (food with low or medium Water content) the temperature T does not rise so quickly. Then the stable frequency level during boiling (cooking) used as a reference level to perform a calibration with regard to 100 ° C. When the water has escaped, it falls the frequency, and the performance of the cooking zone is determined at a particular relative value f1 switched off in relation to 100 ° C: Notwithstanding this, Fig.
  • a temperature curve T (t) which in the area of the boiling point has its course from a previously increasing approximately linearly into subsequently approximately constant Course and in the area of empty or dry cooking its before constant course into an approximately linear increase thereafter
  • a frequency course f (t) can be assigned, which in Range of the boiling point its previously linearly decreasing Course into a course that is approximately constant thereafter and in the area the empty or dry cooking has its previously approximately constant course changes to a course that declines approximately linearly thereafter.
  • This is fast in both the T (t) course and the f (t) course Empty or dry cooking with B1 and the slow empty or Dry cooking marked with B2.
  • the f '(t) course S the span f '(t) with the heating of an empty pot corresponds.
  • the temperature control could then function as a thermostat, for example be performed.
  • the performance of the cooking zone can be set to two different levels P-high and P-low (e.g. P1 and P2) using two calibration curves f (T, P-high) and f (T, P-low) are connected.
  • the frequency f is then measured continuously and the temperature T from the Calibration curves derived depending on what level of performance is being used. If the calculated temperature T-meas is greater than the set temperature T-set, the Cooking zone fed the lower power P-low. Is T-meas smaller than T-set, the cooking zone receives the higher power P-high (Fig. 7). This way the pan or the pot kept at a clearly constant temperature level.
