Definitions

  • the invention relates to a temperature control device for ovens with several heating systems, for example for Top heat, bottom heat, recirculation mode, grill, with one Temperature sensor in the oven space for specifying the actual temperature value for an electronic controller for regulation the oven temperature to predefinable setpoints, the Controller different controller parameters depending of the heating system switched on and / or each activated combination of heating systems for Controller adjustment can be fed.
  • Means for detecting the temperature gradient at the temperature sensor and to compare the detected temperature gradient with the various heating systems and / or Combinations of heating systems associated with saved Temperature gradients are provided that each saved Temperature gradient a controller parameter or a Set of controller parameters is assigned and that depending the assigned by comparison Temperature gradient of the controller with the corresponding one Controller parameters or set of controller parameters can be applied is.
  • the temperature control device can in advantageously on the cost-intensive and prone to failure Control inputs of the controller waive, and also a corresponding assembly and connecting lines to Function selection switches can be omitted.
  • the each switched on heating system or the respectively switched on Combination of controller parameters assigned to heating systems are automatically assigned internally to the control loop, so that no additional lines or external Switching operations would be required.
  • the assignment of the suitable controller parameters are therefore only via Software when training the controller as a microcomputer. By recording the respective temperature gradient to select the controller parameter (s) assigned this selection is practically independent of one Function selector switch.
  • the controller which is designed in particular as a microcomputer in an advantageous manner in addition to the detection of the temperature gradient and / or for comparison with the saved ones Temperature gradients and / or to assign the corresponding Controller parameters or set of controller parameters educated. Thus, despite being more comfortable and extensive Functions of the hardware effort minimized.
  • Offsets and / or in particular are the controller parameters Gain factors and / or tables for controller settings provided, each depending on the control loop of the recorded temperature gradient.
  • a storage arrangement For storing the temperature gradients and / or controller parameters a storage arrangement is preferably provided, for the in particular the already existing memory of the microcomputer used as a controller can be.
  • the temperature gradients are expedient filed in a table.
  • a flow chart to explain the mode of operation is in the only one Drawing shown and in the description below explained in more detail.
  • Ovens for example ovens
  • These heating systems act it is, for example, those for generating top heat and / or bottom heat, for circulating air or hot air operation, for a grill or the like.
  • a temperature controller Used to set a desired oven temperature a temperature controller on the part of a single temperature sensor The actual temperature value is supplied in the oven compartment becomes.
  • the temperature setpoint is over a corresponding Setting element, for example a rotary switch, fed to the temperature controller.
  • a function selector switch or a single button or a single switch is switched on by a switch 10 the determination of the temperature gradient in one calculation step 11 performed. In principle, this is done by a time derivative of the signal from the temperature sensor.
  • a comparison step 12 the detected Temperature gradient with different, in a table stored temperature gradients compared that typical of the various heating systems and different possible combinations of heating systems are. These typical temperature gradients are, for example stored in the memory of a microcomputer that as Regulator is used. This microcomputer can in addition to its controller function, there are other functions take over how the detection of a heating system or due to a certain combination of heating systems the comparison of a detected temperature gradient with stored typical temperature gradients.
  • controller parameters can, for example Offsets, amplification factors and other typical control specifications be used to influence and adjust the Controller behavior are required. In the simplest case it can only be a single controller parameter act.
  • the controller parameter or parameters corresponding tables can also be stored in the memory of the Microprocessor.
  • controller parameters selected in this way or only a single controller parameter are now in step 14 to adjust the controller behavior the temperature controller supplied so that the temperature in an optimal manner T can regulate in the oven space or cooking space.
  • a controller parameter can only from a correction value or a correction factor or a correction function for the actual temperature value or the temperature setpoint.
