Definitions
- the present invention relates to a method for temperature control of a heating element, which is heated inductively by an inductor, to which electrical power is supplied via a control circuit and a corresponding control circuit, as well as an induction hob and an induction oven with such a control circuit.
- the heating of a heating element by induction is known.
- This principle is e.g. used in induction hobs, in which the heat of a cooking vessel is generated in the bottom of it by induction.
- a method for measuring and regulating the temperature of an inductively heated cooking vessel in an induction cooking device is known.
- This method measures a parameter of a circuit that supplies the inductor with electrical power.
- Parameter is influenced by the heating of the cooking vessel, so that its value varies with a change in the temperature of the cooking vessel.
- the temperature of the cooking vessel can be determined from the measured value of the parameter using a temperature characteristic of the parameter.
- the invention has for its object to provide a method for temperature control of an inductively heated heating element, which works independently of the state of the heating element and for different heating elements.
- This object is achieved by a method of the type mentioned at the outset in that the temperature control is activated at a first point in time, that depending on at least one electrical variable of the control circuit, which depends on the temperature of the heating element, a reference value or a at this first point in time Desired value is determined that, depending on the electrical quantity, a comparison value or an actual value and a deviation of this comparison value from the reference value is determined at least at a later point in time, and that power is supplied to the inductor depending on the deviation, so that the temperature of the heating element is regulated to a constant value corresponding to the reference value.
- control circuit of the type mentioned in the introduction in that the control circuit comprises an operating element for activating the temperature control, in that the control circuit has at least one measuring device for determining at least one electrical variable of the control circuit, which depends on the temperature of the heating element, includes that the control circuit is designed to determine a reference value dependent on the electrical variable at an activation time of the temperature control and to determine a comparison value dependent on the electrical variable at least at a later point in time, that the control circuit is a comparison unit for determining a deviation of the comparison value from the Includes reference value, and that the control circuit comprises a control unit for controlling the power regulator depending on the deviation, for temperature control of the heating element to a reference value t corresponding constant value.
- the reference value is determined at the time of activation of the temperature control depending on the electrical variable of the control circuit and this is compared with the comparison value which is determined at least at a later point in time depending on the electrical variable of the control circuit is ensured in a simple manner. that the temperature control to a temperature corresponding to the reference value is independent of the choice of the heating element. It is also advantageous that the temperature of the heating element can thus be regulated without knowledge of a specific temperature characteristic of the electrical quantity for the heating element. In this way, the temperature control is functional even if the heating element is positioned inaccurately to the inductor.
- the temperature control can be activated by a user by actuating an operating element, which is in particular at least one switch or at least one touch sensor.
- an operating element which is in particular at least one switch or at least one touch sensor.
- This allows the user to determine the desired temperature of the heating element by activating the temperature control, for example in an induction cooking zone of an induction hob, when water in a cooking vessel starts to boil on this induction cooking zone or a food in the cooking vessel on one that is subjectively determined by the user Temperature should be kept.
- the temperature of the heating element such as the cooking vessel, is maintained after activation of the temperature control, without having to determine the absolute temperature of the heating element with a sensor.
- the electrical power is automatically regulated in order to keep the temperature of the heating element at the temperature corresponding to the reference value and manual readjustment of the electrical power by the user is also not necessary if, for example, cold food is still fed into the cooking vessel during a cooking process.
- the comparison value of the electrical variable can advantageously be determined at predetermined, in particular periodic, time intervals. In this way the accuracy of the temperature control is increased, since changes in the temperature of the heating element by e.g. external influences are recorded at regular intervals and the electrical power supplied to the inductor is adjusted accordingly in order to keep the temperature constant.
- the reference value and / or the comparison value are determined at a predetermined frequency of the electrical variable. This procedure has the advantage that frequency-dependent influences of the heating element or the determination of the reference value or the comparison value can be avoided, as a result of which the accuracy of the temperature control can be increased.

- Input voltage v t is generated using a voltage divider 14, which has two resistors Kl,
- R2 comprises, reduced and by means of a rectifier 15 to a rectified. Input voltage v, converted.

- An output voltage v 0 is present at the inductor and an output current i 0 flows .
- These two electrical variables v 0 , i 0 are influenced by a change in resistance of the heating element 3, which depends on the heating element 3 and its temperature T.
- the output current i 0 is detected with the aid of a current-voltage converter 18, at the resistor R3 of which a voltage vi is applied which is proportional to the output current i 0 . is.
- FIG. 3c schematically shows the detected time profile of the output voltage v 0 and the output current i 0 .
- a further, alternative measured variable, which depends on the temperature T of the heating element 3, is, for example, a phase shift ⁇ t between the output voltage v 0 and
- Output current i 0 which can be determined, for example, on the basis of a zero crossing Nl of the output voltage v 0 and a zero crossing N2 of the output current i 0 .

- FIG. 4 shows a flow chart of the temperature control of the heating element 3.
- the temperature control is carried out by a control signal
- a reference value F R is determined almost simultaneously with the activation of the temperature control from the current value of the function F, which is dependent on at least one of the electrical variables, v 0 , i, P, / of the control circuit 2, which of the temperature T of the heating element 3 depends.

Since the averaging period t is typically of the order of 10 to 800 milliseconds, this period of time is negligibly small compared to the typical duration d of the power control L of 5 to 15 seconds. As soon as the temperature control is activated, the electrical power supplied to the inductor 6 is reduced from the power value Pl to a lower power value P2 in order to keep the temperature value T1 of the heating element 3 constant.
- the heating element 3 is cooled by an external influence, for example by supplying cold liquid to a cooking vessel 3.
- This cooling of the heating element 3 to a temperature value Tl is detected by the deviation of the comparison value F v from the reference value F R.

- the electrical power P supplied to the inductor 6 can be gradually reduced to a value P4.
- This power value P4 is now fed to the inductor 6 in order to keep the heating element 3 at the constant temperature value T1.
- the temperature control remains active until it is deactivated, for example by the user actuating the control element 9.
