Definitions

the invention relates to a method for temperature control for a sensor-controlled cooking unit consisting of a cooking device, sensors and hob, for example a glass ceramic hob, with both the hob and the cooking appliance May contain sensor-specific configurations.
EP 0 658 067 A1 describes a Control for household appliances for the evaluation of sensor signals, especially for radiant heating in glass ceramic cooktops, known, the control sensory operated, direct and indirect temperature measurements of the decoding the respective hotplate of a glass ceramic cooktop and compares it with typical temperature profiles, and wherein the controller performs a pot detection and in In the event of a hotplate idle, the control unit controls the radiant heating switches off.
the object of the invention is therefore the temperature of the food in cookware on troughs by an infrared sensor to measure without contact, the signals of this sensor too a controller, through which the food temperature led as precisely as possible to a setpoint and held there shall be.
Figures 1, 2 show both the starting process and the holding process of the regulation in the case of conventional regulation and almost ideal regulation recognizable.
the controller estimates the approach from the difference a first target temperature of the start value and the setpoint up to which the cookware is heated up without the heating of the hotplate being cycled. In order to the fastest possible heating is achieved. Is the first When the target temperature is reached, the hotplate is switched off. Because of the possible heat capacity of the hotplate the temperature of the cookware can be reheated for a short time become and rise slightly, the temperature of the cookware so the actual target temperature of the Cookware is approaching.
the controller that is equipped with intelligence is determined by experimentally determined times Switched off the hotplate after the start-up process be on operation heating the setpoint.
the holding process of the setpoint is made up of two sections. This is particularly important if the temperature of the food has to be kept relatively constant over a long period of time.
the control device switches to the holding process I.
the setpoint is held by simply comparing the temperatures T setpoint and T actual with the corresponding switching of the control device with respect to the heating device of the hotplate.
the control system can also intelligently take into account on and off times for switching cycles of the hotplate heating, which defines the current energy consumption of the cookware. As a result, the holding process I can be further optimized.
the minimum on and off times of the hotplate are determined, and the holding process II is initiated. From now on, the controller will automatically cycle with the previously determined switching times. If the temperature of the food drifts, the switching times are corrected so that the on and off times of the hotplate remain minimal.
the strict program sequence sequences of a regulation consisting of the starting process, the stopping process I and the stopping process II, are defined. 3 can be seen from the start of the control 31, the subsequent step that the control takes in the control process, 32, namely firstly estimating the first target temperature, secondly switching on the hotplate. This happens in the start-up process.
control determines that the desired target temperature has been reached, it switches off the hotplate in step 34 and waits for the temperature of the food to settle.
step 33 if the position target temperature is negated, the hotplate continues to be operated until the target temperature of the food to be cooked is reached.
the evaluation of the actual temperature to the target temperature after the transient process follows.
the comparison temperature check carried out in step 35 leads, in the event that the actual temperature has already exceeded the target temperature, to switching off the hotplate and registering the necessary switching time. If the actual temperature has not yet reached the target temperature, the hotplate remains switched on and the necessary switch-on time until the target temperature is reached is registered by the intelligent control.
This step 36 leads to the fact that the hotplate is continuously clocked with the determined switching times in the controller step 37, the switching times having to be corrected continuously if necessary.
control according to the invention are, in particular, that by dividing the control process into a start-up towards the setpoint and the stages of maintaining the setpoint of the temperature, overshoots and undershoots can be kept within tolerable limits, if necessary effectively avoided. This is important for cooking processes, as it is particularly overshoots that cause the food to burn, boil and boil over.
the division of the holding process in the form shown in FIG. 4 allows the temperature setpoint T Soll to be controlled with a minimum possible control amplitude.
