Definitions

  • the present invention relates to a cooking appliance and a method for operating a cooking appliance and in particular for detecting an empty operation of a cooking appliance equipped with at least one high-frequency heating appliance.
  • a food to be cooked is dielectrically heated in at least one cooking chamber and the high-frequency heating device is controlled by at least one control device.
  • Cooking appliances with a microwave function provide a quick and particularly gentle cooking method for preparing food.
  • the microwaves are generated using a magnetron and passed through a wave channel in the cooking chamber.
  • a stirrer is often provided.
  • Many microwave ovens also have a turntable with which the food can be variably aligned in the radiation field.
  • microwave ovens usually can not be operated with an unloaded oven.
  • the reason for this is usually that the output from the magnetron power must be sufficiently absorbed, otherwise a large part of the radiation power is reflected by the walls in the oven and passes through such reflections back to the magnetron.
  • the magnetron will heat to a critical level due to the reabsorbed radiation and may therefore be damaged.
  • the reflected radiation power and other components are heated and thus possibly damaged, such as the shaft channel and other Garrauminnenmaschine.
  • the manufacturer when using a microwave oven, the manufacturer usually points out that the user must never operate the appliance without loading the cooking space. Often, the instructions for use of the microwave oven are particularly emphasized. Often, appropriate instructions are attached to the microwave oven. The problem with these embodiments, however, is that the user can usually still start and operate the microwave oven without loading. As a result, the device can be considerably damaged and even destroyed in the worst case.
  • the method according to the invention serves to operate a cooking appliance equipped with at least one high-frequency heating device.
  • the method is used to detect an empty operation of such a cooking appliance.
  • the cooking appliance is provided for dielectric heating in at least one cooking chamber.

B. an operation without food to be reliably detected in the oven, since in this case the high-frequency heater or one of its components heated recognizable by the reflected radiation power.
  • a further advantage is that the heating power of the high-frequency heating device is automatically reduced if the detected temperature indicates insufficient cooking space or even empty operation. As a result, the operation is made much safer at an empty operation, as due to the reduced heating power damage or even destruction of the device can be reliably avoided.
  • reducing the heating power also means that the heating operation of the high-frequency heating device is at least temporarily completely shut down.
  • the reduced heating power or reduced power level is then retained for the cooking time to be continued or can continue to be reduced if the conditions require it. It is also possible that, depending on the detected temperature at least one state of emergency is triggered.
  • the operability of the device may be limited to certain functions. For example, then no heating operation is possible.
  • the temperature detected by means of the sensor device can also be a characteristic variable for a temperature.
  • a characteristic variable for a temperature For example, an electrical Resistance and / or electrical voltage are detected whose value (e) is characteristic of a certain temperature.
  • the high-frequency heating device is particularly suitable and designed to generate radiant power for the dielectric heating of food to be cooked.
  • the high-frequency heating device generates radiation power in a wavelength range of microwaves intended for the operation of microwave cooking appliances. Radiation power from another wavelength range or frequency band can also be used.

  • the loading of the cooking chamber is in particular too low, if not enough radiation power can be absorbed and this leads to a critical increase in temperature of device parts and in particular the high-frequency heater and at least one of its components.
  • the empty operation is characterized in that there is no or no suitable food in the oven. Such an empty operation is present, for example, when a user closes a door of the cooking chamber and starts the heating operation, without having introduced anything into the cooking chamber.
  • the idle operation is indicated by the fact that the detected characteristic temperature exceeds at least one threshold value.
  • the threshold value is stored in the control device. It is also possible for at least one characteristic variable for a temperature to be stored as a threshold value.
  • the deposited size preferably corresponds to the size detected by means of the sensor device.
  • the threshold value can also be adapted by means of the control device, for. B. depending on a user-set heating or cooking mode. With such a threshold value, it can be detected particularly reliably whether or not the detected temperature is indicated by an empty operation.
  • the stored threshold value describes a higher temperature than an expected maximum temperature of the component in a designated cooking operation.
  • the intended cooking operation provides at least one food to be cooked in the oven.

  • the threshold may be increased by 2% or 5% or 8%, or even 10%, or even 20% or more, from the expected maximum temperature. The exact increase is thereby adapted to the expected power outputs of the high-frequency heating device.
  • a temporal change of the detected characteristic temperature is registered by means of the control device.
  • the idle operation is preferably indicated by exceeding a predetermined degree of change.
  • at least one function of the temperature over time is considered and evaluated.
  • the temporal change can then be recognized on the basis of the slope of at least part of the function. Possible is another evaluation of such a function, eg. B. based on at least one algorithm.

  • the upper threshold value 661 indicates a maximum temperature, which is usually not expected in a normal and proper cooking operation. Therefore evaluates the Control device, the increased temperature of the anode device 23 as the cause of an empty operation. Thereafter, the power 602 of the high frequency device 13 is shut down by the controller 5. Accordingly, the temperature 600 of the anode device 23 also decreases.
  • a temperature between 10 seconds and 90 seconds is measured. If the temperature exceeds threshold 662, the power is reduced.

This is done here, for example, by a clocking with correspondingly shorter on phases and / or by correspondingly longer off phases or cycle pauses. For example, the power of the high frequency heater is reduced to a nominal power input of about 600 watts. This has the advantage that the temperature 600 in the switched-on clock phases of the high-frequency heating device 13 no longer reaches or exceeds the upper threshold value 661.
  • a complete power reduction may also be provided.
  • a reduction in performance has the advantage that, on the one hand, there is no danger in idle operation and, on the other hand, that a cooking operation is still possible.
  • This is for example advantageous for dry food.
  • Such food can be, for example, popcorn, which can be optimally prepared even with the reduced power.
  • the slope of the temperature profile 660 can also be used to determine how much food to be cooked is in the cooking chamber 4. Since the slope is also dependent on a dielectric moment in the cooking chamber 4, for example, it can also be determined How high the water content in the food is. In addition to a targeted lowering of the power of the high-frequency heating device 13 in an empty operation, this information can also be used for a targeted power control. For example, it can be determined in which performance a food with a certain water content must or can be exposed in order to achieve optimum cooking.
  • the method presented here and the presented cooking appliance 1 allow a very safe and reliable microwave operation, since even without any food in the cooking chamber 4 or with only a very small amount of food the cooking chamber 4, the device 1 and the cooking chamber parts remain intact.
  • the presented here detection of the idle operation by means of a sensor 16 to a component of the high-frequency heating device 13 is a very cost-effective solution, since in addition to the additional equipment with the sensor 16 no costly changes to the hardware on the device 1 must be made.
