Definitions

  • the present invention relates to an inductive cooker and a method for Heating of food according to the generic terms of the independent Claims.
  • the temperature and the Temperature control significantly affects the quality of the food.
  • meat, Fish and sauces must be processed in a very narrow temperature range be so that the optimal taste development comes into its own.
  • Inductive cookers require monitoring or regulation of the temperature.
  • a Temperature measurement on the underside of a ceramic or glass plate as a carrier for pan and food Because of the material thickness and bad Thermal conductivity of this plate takes a long time to change Temperature is registered. This is a major disadvantage since the food is under Possibly overheated long before an operator or any existing operator Temperature control loop can intervene effectively.
  • the state of the art Well-known inductive cookers use the special, inertia Characteristic of inductive heating is not optimal. In addition, usually the measured temperature is not displayed directly, so that the operator is only vaguely Can make ideas about the effective temperature of the food.
  • the technical problem is solved in particular by the fact that a Temperature change of the food to be measured measured without delay, transmitted, is evaluated and displayed.
  • the signaling Sensors are attached so that they are subject to exactly the same changes like the food. Insulating shielding by other elements is bad and has a delaying effect on the result.
  • the invention disclosed here solves the task in a simple way. This is how signaling sensors become placed that they are subject to the same influences as the food. In practice it means that they are "cooked”.
  • the signal transmission between Sensor and an evaluation unit is optimized so that no disadvantage Restriction results.
  • the relevant data is stored on a Display unit so visually represented that it is clear and for the operator updated without delay as actual values are recognizable.
  • the operator has preferably also the possibility of entering a target value for the temperature, which can also be displayed.
  • the relevant data are stored in one Target / actual comparison compared and for temperature control used.
  • the signaling sensors deliver at least one electrical signal, which on the one hand to control a temperature display and on the other hand to regulate the Serve cooking process.
  • a microprocessor By actively regulating the cooking process by means of A microprocessor can be an optimal one from a control point of view seen stable system can be achieved.
  • the adjusting mechanism the control loop is advantageously designed with a very short reaction time, without the risk of the entire system becoming unstable or even tends to rock.
  • the signaling sensors are advantageously in the food or placed immediately next to it. If it is a liquid cooked food, such as For example, a sauce or a cream, the sensors are in a measuring probe this inserted. With solid food, such as meat, the sensors in the Inside the food or in the area of the surface of the food appropriate.
  • the measurement signals generated by the sensors typically relate to the Temperature, humidity or other parameters.
  • the measurement signals are on a microprocessor-controlled electronics hand over the resulting target / actual deviation,
  • the manipulated variable and display value are calculated.
  • the user determines by Specification of the setpoint of the temperature that is shown on a display. On the same or another display shows the effectively measured temperature of the Cookware held. To guarantee optimal success of the food, If necessary, several sensors are used.
  • the performance of the inductive Cooking range is shown on a separate display, so the user turns on at a glance recognizes how much the current cooking output compared to maximum cooking power is.
  • the sensor signals are transmitted between the sensor and the evaluation unit in different ways.
  • the sensors are connected by cable to the Evaluation and display unit connected. Through this cable the sensors supplied with power, and transmit the sensor signal (s).
  • the Data is transmitted as an analog or digital signal.
  • the cables of the Sensors are advantageously connected to the cooker by means of plugs. If the sensors are not connected to the cooker, this is done Temperature monitoring via a sensor that is permanently connected to the cooker is advantageously attached in the region of the pan base. This sensor usually also serves as overheating protection for the cooker.
  • inductive cooking stoves as Alternative to the cable connections a particularly advantageous form of Data transmission between sensor and evaluation unit resp. Display unit used, which can also make targeted use of the inductive magnetic field.
  • the data transmission may have no restrictive effect.
  • the data is at this variant without a direct cable connection, e.g. B. by means of analog or digital Radio signals transmitted.
  • the at least one sensor which the relevant measurement parameters are determined, coupled to at least one transmission unit.
  • This transmission unit transmits a signal which corresponds to the measured quantities clearly correlated.
  • the transmitted signal is then replaced by a Recipient recorded and after a suitable preparation of the evaluation, display and control supplied.
  • the transmitter unit is supplied with energy, for example, via energy stores such as batteries or accumulators.
  • energy stores such as batteries or accumulators.
  • Another very elegant and special An advantageous possibility is the targeted use of the anyway existing inductive field by a coil. This coil is targeted like this placed that a voltage is induced in it by the inductive field. This Voltage as an energy supply for recording the measured variables and for Data transmission used.
  • the transmitter units and the receiver unit are designed so that several Measurement signals are differentiated and evaluated at the same time. So it is possible use different sensors at the same time and the signals of the individual Differentiate sensors and z. B. on different display units to represent. In addition, one or more measurement signals for controlling the Serve cooking process. Leave the signals emitted by the transmitter units are clearly different from each other, so that the user can Measured variable of each sensor is informed.
  • the invention is designed so that a Transmitter / sensor unit begins signal transmission as soon as it is switched into an inductive one Field is introduced.
  • temperature distributions in the Detect food or, for example, on a grill surface can also a change in quantity can be determined.
  • the measured temperature profiles serve to control the heating surface.
  • the inductive cooker according to the invention for heating cookware has Means for controlling the heating power and at least one sensor Temperature measurement on.
  • the output signal of the at least one sensor is one Control variable for the means for regulation.
  • the at least one sensor is immediate attachable in or with the food.
  • the cooker contains a display unit visual representation of the output signal of the at least one sensor.
  • the inventive method for heating food uses one inductive cooker according to the invention, which means for controlling the Contains heating power and at least one sensor for temperature measurement.
  • the output signal of the at least one sensor is used as a manipulated variable for the means used for regulation.
  • the at least one sensor is directly in or at Cookware attached.
  • the output signal of the at least one sensor is determined using a display unit on the inductive hob is shown visually.
  • Figure 1 shows schematically an inductive cooker 1 with a partially cut pan 2 in a perspective view.
  • a magnetic field (not shown in detail) is generated under a hob 3. This causes an inductive heating of a pan base 10.
  • a plurality of sensors 19.1, 19.2, 19.3 are accommodated in a sensor rod 20 and releasably connected to the inductive cooker 1 by means of a cable 21 via a plug connection 22.
  • the signals from sensors 19.1, 19.2, 19.3 are evaluated individually or by averaging. By attaching several sensors, a higher resolution of the temperature stratification in the food can be achieved, respectively. a statement about the filling quantity or the change in the filling quantity in the pan (for example during a boiling process).
