Definitions

  • the present invention relates to a method for controlling the temperature of a heating element, which is inductively heated by an inductor, which is supplied via a control circuit electrical power and a corresponding control circuit, and an induction cooktop and an induction furnace with such a control circuit.
  • the heating of a heating element by induction is known.
  • a power loss of a high-frequency alternating field, which is generated by an induction coil, the so-called inductor, by magnetic coupling in a part of the heating element leads to the heating of the heating element.
  • This principle is e.g. used in induction hobs, in which the heat of a cooking vessel is produced in the bottom by induction.
  • US 3,781,506 is a method for measuring and controlling the temperature of an inductively heated cooking vessel in an induction cooker known.
  • a parameter of a circuit is measured, which supplies the inductor with electrical power.
  • This parameter is influenced by the heating of the cooking vessel, so that its value varies with a temperature change of the cooking vessel.
  • the temperature of the cooking vessel can be determined from the measured value of the parameter based on a temperature characteristic of the parameter.
  • US Pat. No. 6,163,019 is a resonant frequency induction furnace, in particular for melting metals, known in which, in order to achieve a preset power level of the heating elements, an initial conduction time (pulse width) of the heating elements is predetermined and then the heating elements driven with the following enlarged pulse width until the predetermined heating power is reached.
  • the invention has for its object to provide a method for controlling the temperature of an inductively heated heating element available, which works regardless of the state of the heating element and for different heating elements.
  • the temperature control is activated at a first time that, depending on at least one electrical variable of the control circuit, which depends on the temperature of the heating element, at this first time a reference value or a Specified value is determined that depending on the electrical variable at least one later time a comparison value or an actual value and a deviation of this comparison value is determined by the reference value, and that the inductor depending on the deviation power is supplied, so that the temperature of the heating element is controlled to a constant value corresponding to the reference value and by the further features of claim 1.

It is also advantageous that the temperature of the heating element can thus be controlled without knowing a specific temperature characteristic of the electrical variable for the heating element. In this way, the temperature control is functional even if the heating element is positioned inaccurate to the inductor.
  • the temperature control can be activated by a user by actuation of a control element, which is in particular at least one switch or at least one touch sensor.
