Definitions

  • the invention relates to a method for supplying power to a plurality of induction coils in an induction device and to an arrangement for carrying out this method.
  • ferrites for magnetic field guidance are provided under induction coils. These ferrites are subject to magnetostriction, ie a change in length, depending on the operating frequency of the induction coil. This is at least partially true for used cookware.
  • the working frequency of induction coils is usually above the audible range, the noise can be heard through intermodulation with another powered induction coil.
  • audible mixing products can arise from the frequency difference of the operating frequencies and their harmonic harmonics.
  • Further intermodulation can occur when two frequency converters for the induction coils are connected to a common supply voltage are. In this case, one frequency converter modulates the supply voltage for the other frequency converter.
  • the ES-A1-2201937 describes a method for powering a plurality of induction coils in an induction device, wherein in each case a frequency converter supplies power to each induction coil.
  • cut-off frequencies 2 kHz and 14 kHz are used, which are set as a frequency difference if the outputs are to differ.
  • the upper cutoff frequency an operation of the induction coil can be achieved, which is at the upper end or even outside the human hearing threshold.
  • the US-A-4542273 describes a similar method for powering a plurality of induction coils in an induction device.
  • each induction coil has its own power supply. If two or more resonant circuits of the induction coils are operated, they operate at the same frequency or a frequency difference is equal to zero. This avoids unwanted noise.
  • the invention has for its object to provide an aforementioned method and an arrangement with which the problems of the prior art can be avoided and in particular an advantageous operation of multiple induction coils is possible with the lowest possible noise.
  • the induction coils at the respective start of operation ie when several coils are to be operated, with the required values, which have been input by an operator for each induction coil via an operating device, first operated at high frequency or highest operating frequency of the system.
  • the function as pot detection coils is particularly advantageous. This makes it possible to detect whether an appropriate cooking vessel is to be heated via an induction coil. Then the frequencies are lowered with the frequency converters. This takes place until the total power of the induction coils corresponds to the total power of the required values for the individual powers. Since this still takes place at the same frequency, as a rule, ie at different required values for the power P, the one induction coil operated with more power than required and the other with less power.
  • the frequencies are very close in operation.
  • the frequency difference is even 500 Hz and less.
  • the frequency difference is in a very high range for the human ear or is no longer in the audible range.
  • the method operates exactly two induction coils, as described in the present application.
  • the possible variation of the operating frequencies and setting a certain frequency difference is particularly good and predictable possible.
  • each induction cooker may have a single induction coil.
  • an induction cooking station may have an induction coil which consists of several partial coils and / or which can be driven by a plurality of power generators or frequency converters. This then corresponds to so-called multi-circuit heaters, as they are known from radiant heaters.
  • Induction coils in particular for household use, such as an induction oven or an induction hob, are advantageously operated in a frequency range of about 16 kHz to 100 kHz.
  • a clocking or alternating operation of the induction coils can take place if the required values do not change.
  • the sum of the powers at common frequency f g corresponds to the sum of the powers at different frequencies. she is at the same time the required total power for both induction coils.
  • Another possibility may be to first try to satisfy the conditions with a first lower frequency difference, for example the said 18 kHz. If this is not the case, or if the intended algorithm does not work for the adjustment, then it can be attempted with a second somewhat higher frequency difference of about 24 kHz.
  • a first lower frequency difference for example the said 18 kHz.
  • FIG. 1 an induction hob 11 is shown in section.
  • an operating device 15 is arranged with two rotary knobs 16 and 17 for the power setting.
  • the representation of the operating device 15 is to be understood very schematically and of course all other controls can be provided, in particular also so-called touch switch.
  • the operating device 15 is connected to a controller 18 and, among other things, passes on the control commands by adjusting the rotary knobs 16 and 17 to the controller 18.
  • the controller 18 in turn is connected to a first inverter 19 which is supplied with a frequency f 1, a first inductor L1, and with a second inverter 20 which is supplied with the frequency f 2, a second inductor L2.
  • the induction coils L1 and L2 are arranged in a known manner below the hob plate 13. On its underside, ferrites 21 are arranged in a likewise known manner for influencing the magnetic field generated by the induction coils L. Above the induction coils L1 and L2 are on the hob plate 13 cookware 22 and 23 attached. The larger cookware 23 illustrates to what extent the coupling of a higher power should or should be done here. This can also be seen in the position of the rotary knob 17, which is further adjusted to the right and thus to a higher power level than the left rotary knob 16. Here, the rotary knob 16 is used to adjust the power for the induction cooker formed by the left induction coil L1 and the right rotary knob 17 for the induction cooker formed by the right induction coil L2.
  • FIGS. 2 and 3 For example, as will be described below together, it is shown how the inductors L1 and L2 are supplied with power P at a certain frequency of the supply voltage. The curves for the frequency and the power are shown in dashed lines for the coil L2.
  • both induction coils L1 and L2 are operated with common frequency, namely with f max in the sense of a pan detection function. This is sufficiently known to the person skilled in the art and need not be explained in more detail here.
  • suitable cookware namely the cookware 22 and 23, are set up and thus an operation is possible. Accordingly, power is released by the controller 18 and the frequency converters 19 and 20.
  • the frequency set by the frequency converters 19 and 20 is lowered by an equal value to the value f g .
  • This value f g results from the specifications that both induction coils L1 and L2 should be operated at the same frequency, namely f g , and with the powers P 1 (f g ) and P 2 (f g ).
  • the powers P 1 (f g ) and P 2 (f g ) result from the specification with f g and the set and predetermined value for the total power generated via the rotary knobs 16 and 17.
  • the induction coil L1 is operated with the power P 1 (f g ), which is greater than the average intended power P 1 .
  • the inductor L2 is operated at a power P 2 (fg) which is below the mean intended power P 2 lies.
  • the operated at excessive power inductor L1 is increased in terms of their operating frequency f 1 by a frequency difference .DELTA.f, which is 18 kHz in the present case.
  • both operating frequencies are lowered with the fixed frequency interval ⁇ f.
  • the lowering takes place until the frequencies f v1 and f v2 are reached with the powers P 1 (f v ) and P 2 (f v ).
  • the sum of P 1 (f v) and P 2 (f v) the sum of P 1 (f g) and P 2 (f G).
  • the above-mentioned frequency difference of 18 kHz during the operating mode c) is present, which means a barely audible noise.
