Definitions

  • the invention relates to a method for detecting the loading state of a cooking chamber of a cooking appliance with food that is cooked under microwave loading, and a cooking appliance for performing such a method.
  • a cooking appliance in which can be closed by comparing the performance of the radiated microwave radiation in a cooking chamber with the power of a microwave radiation reflected in the cooking chamber on the absorption of arranged in the cooking chamber food.
  • the microwave radiation generated by a magnetron is radiated by means of a waveguide and a directional coupler, in the cooking chamber, wherein a portion of the cooking chamber located in the microwave radiation is reflected back into the aforementioned waveguide, and the back-reflected microwave radiation coupled via the directional coupler from the waveguide and a microwave detector is supplied.
  • a disadvantage of the aforementioned prior art is that for determining the loading state of a cooking chamber at least two variables included, namely on the one hand, the input power of the microwave radiation in the oven or the power of a microwave generator and on the other the reflected from the cooking and not absorbed by the food microwave power.
  • the more noisy measured variables are included in the calculation of the load, the more the calculated value of the load will be subject to undesirable fluctuations.
  • it is disadvantageous to continuously monitor the microwave power in the cooking chamber via a corresponding detection device during the cooking operation, since the detection device itself absorbs microwave power, which is thus no longer available for heating food to be cooked.
  • An alternative system for detecting the amount of charge in a microwave oven is from the US Pat. No. 6,867,402 B1 known.
  • the load detection system described therein is used to determine the loading state in the cooking chamber by irradiation of a high-frequency energy impact, in particular an ultrasonic energy burst, and measurement of the reflection of the energy impact. Based on the time difference between the emitted and the reflected signal, a controller decides whether a load is present in the cooking chamber or not.
  • the KR 100 320 715 B discloses a method for optimally adjusting the microwave output to the load of a microwave oven, regardless of temperature changes of a food. After a magnetron and a turntable are turned on, in the said method for this purpose, the leakage radiation of the microwaves per revolution the turntable measured. After this measurement, the turntable is turned off and then determines a time to minimize, ie to decay, the leakage radiation of the microwaves. The time constant thus determined is compared with a reference value. If the genante time constant exceeds the reference value, an unloaded state of the cooking chamber is detected and issued an error message.
  • the invention has for its object to further develop the generic method such that the disadvantages of the prior art are overcome.
  • a detection of the loading amount of the cooking chamber is to be made possible.
  • This object is achieved in that the cooking of the food at least one microwave generator activated and disabled at least one microwave detector and disabled to measure the loading state of the microwave generator and the microwave detector is activated, the Abkling of stored during cooking in the oven microwave radiation, energy and / or performance is evaluated for measurement, comparing with at least one stored reference value to the load state.
  • the reference value for the loading condition for at least one load of food and / or microwave absorption in the food is determined, preferably the reference value from the decay of the unloaded cooking chamber is determined, in particular in the context of a calibration measurement.

  • a cooking device with a cooking chamber, at least one microwave generator, at least one microwave detector, at least one antenna for coupling microwave radiation into the cooking chamber and for coupling microwave radiation from the cooking chamber and a control or regulating unit for carrying out a method according to the invention.
  • the cooking chamber is at least partially limited by metallic, microwave radiation reflecting surfaces or walls and forms a microwave cavity, can be stored in the microwave energy during cooking.
  • the invention also proposes that the microwave generator and the microwave detector are at least partially connected via at least one common line and / or at least one antenna for coupling and decoupling microwave radiation into and out of the cooking chamber.
  • the microwave generator and the microwave detector are connected to the control unit via at least one at least partially common control line for receiving a common control signal and / or via at least one at least partially common signal line, the control signal simultaneously deactivating the microwave generator and Activation of the microwave detector causes.
  • the microwave detector comprises at least one high-pass filter, in particular comprising a capacitor and a coil, for filtering out low-frequency interference, at least one rectifier, in particular comprising a diode, and / or at least one low-pass filter, in particular comprising one Capacitor and a resistor, for filtering out a DC component of a signal, wherein preferably the low-pass filter is connected upstream of the rectifier and the rectifier the low-pass filter.
  • a control voltage to the microwave detector can be applied, which in particular via a resistor and a parallel diode generates a control current, which is preferably the base input of a transistor, in particular bipolar transistor, supplied.

  • a determination of a loading state in the cooking chamber of the cooking appliance can be done by evaluating the time decay behavior of the microwave energy stored in the oven. It is particularly advantageous that the determination of the loading condition by measuring only one size, namely the power of the microwave radiation remaining in the oven, can be determined as a function of time. Furthermore, the invention provides the advantage that the time-delayed detection of the decaying microwave radiation after switching off the microwave generator unnecessary consumption of Mikrawellenenenergy, as it occurs in the case of continuous detection of the microwave power in the cooking chamber during the cooking operation, is avoided.

  • the rate of decay depends on the absorption factor P A / P IN in the food to be cooked and the loss factor P L / P IN of the cooking chamber cavity. The higher the absorption factor or the loss factor is or are, the higher is the decay rate and the shorter is the decay time of the microwave energy remaining in the cooking chamber 2.
  • the loss factor P L / P IN is a device constant that can be determined, for example, as part of a calibration measurement. By measuring the decay characteristic, the absorption factor P A / P IN of the cooking product 4 can be inferred, which in turn determines the loading quantity depending on the type of food 4, selected from a group comprising meat, vegetables, frozen meals, fish or the like.
  • the generator 20 and the detector 30 are synchronously controlled by a control unit 40 of the cooking device 1 via a common control line 41.
  • a control voltage U I > 0 can be applied to the common control line 41, which activates the generator 20 and deactivates the detector 30. Switching the control voltage to 0 V in turn leads to a deactivation of the generator 20 with simultaneous activation of the detector 30.

  • the microwave radiation present in the cooking chamber 2 via the antennas 9, the corresponding lines 10, 11 and the feed line 31 in the in Fig. 3 illustrated detector 30 ' is coupled, so that a voltage between an input 60 and the ground potential GND of the detector 30' is applied.
  • the incoming signal then passes first a high-pass filter, consisting of a capacitor C 1 and a coil L 1 . This high pass filter eliminates low frequency noise in the signal. Then the filtered signal is rectified by means of a diode D 1 .

  • the determination of the loading amount according to the inventive method can be performed at any time within a cooking program or cooking program step and optionally also repeated, for example, to track the change in the absorption behavior of the food during a cooking program and adjust the cooking program accordingly.
  • An alternative to determining the absorption factor P A / P IN of the food to be cooked is the use of an integrator within the control unit for integrating the demodulated in the detector temporal envelope of the decaying microwave radiation.
  • the value output by the integrator would therefore be proportional to the microwave energy stored in the cooking chamber and would have to be compared with the power of the microwave generator generated during the cooking operation to determine the absorption factor of the food.
