Definitions

  • the present invention relates to a method for operating a cooking field device and a cooking field device with which such a method can be carried out.
  • the invention relates to a cooking field device with at least one hob with a plurality of inductors for heating of parked on a workspace of the hob cooking vessels.
  • the pots can often be parked at almost arbitrary positions.
  • the inductors covered by a pot are detected and used to heat the pot.
  • Such a so-called full-surface induction offers improved comfort compared to hobs with fixed cooking positions, since the cooking surface can be optimally utilized.
  • the hob can be divided individually.
  • pots with different ground geometries can be heated evenly.
  • the inventive method is used to operate a cooking field with at least one hob.
  • the cooktop comprises a plurality of inductors for heating cooking vessels placed on a working area of the cooktop.
  • the plurality of inductors comprises at least one inductor group having a first inductor and a second inductor and a third inductor.
  • the currently at least partially covered by cooking vessels inductors are registered by at least one detection device and assigned to the cooking vessels.
  • a phase position of an inductor current of at least one of the inductors of the inductor group is adjusted by at least one phase influencing device.
  • the phase angle of the inductor current of the inductor is set relative to a phase position of at least one adjacent inductor.
  • the method according to the invention has many advantages.
  • a significant advantage is that by adjusting the phase position, the orientation of the magnetic field generated by the inductor current changed and thus the energy input into one or more cooking vessels can be selectively influenced. As a result, a further degree of freedom for adjusting the energy input is obtained in a cooking vessel.
  • the adjustment of the phase position can preferably be used in addition to the adjustment of the power of the inductor per se in order to optimally adapt the energy input.
  • an average power supply may be initially adjusted or the power supply set for one of the two pots.
  • the energy input can be additionally regulated in addition to the inductor power per se. Possible but is also that the energy input is regulated solely by adjusting the phase angle of the respective inductor current.
  • the inventive method thus allows an energy input, which is optimally adapted to the set and desired user levels by the user. Due to the correspondingly accurate compliance with the given power levels, optimum cooking results can thus be achieved.
  • the phase influencing device is preferably suitable for setting the phase position of a plurality of inductors. Particularly preferably, the phase positions of all inductors of the cooking field device can be adjusted. But it is also possible that only a certain number of inductors is provided for adaptation by the phase influencing device. It is possible that, for example, only every second inductor is designed to adjust the phase position.
  • the cooking field device may comprise at least one or just one inductor group.
  • all inductors of the cooking field device then belong to the one inductor group. It is also possible that two or more inductor groups are provided. The number of inductors between the inductor groups may vary or be the same.
  • the phase position for adjusting the energy input is set in a region between at least two inductors.
  • the energy input is adjusted in addition and / or independently of an inductor power.
  • the inductor power is preferably controlled by means of at least one control device as a function of a power level specified by the user.
  • the inductor power is in particular the power which is supplied to the inductor for generating a magnetic field.
  • the control device is suitable and designed to regulate the inductor power.
  • the flow direction of the electric current in at least one inductor of the inductor group is changed.
  • the flow direction of the electric current in at least one inductor of the inductor group is adjusted relative to the current direction in at least one adjacent inductor.
  • Such an embodiment has the advantage that the change of the flow direction of the electric current offers a relatively simple and inexpensive possibility for adjusting the orientation of the magnetic field of the inductor.
  • the flow direction of two adjacent inductors can be switched either in opposite directions or in the same direction. This results in z. B. in opposite directions of flow Induktorstrom same direction magnetic fields or in the same direction flow directions opposite magnetic fields.
  • the phase of the inductor current is shifted by half a wavelength in at least one inductor of the inductor group.
  • a phase shift allows an inexpensive reorientation of the generated magnetic field in the use of AC driven inductors.
  • the present phase of the electric current is taken into account in at least one further inductor of the inductor group.
  • the inductor current changes in particular periodically wave-shaped and preferably sinusoidally, at least in a rough approximation.
  • different phase positions are set for at least two of the inductors of the inductor group.
  • the same direction magnetic fields are generated, so that the energy input is amplified in a cooking vessel, which covers the two inductors at least partially.
  • This has the advantage that in addition to a predetermined power level, an additional reinforcement of the power input is possible. This allows better cooking results especially when an inductor is covered by two pots and one of the two pots is desired to have a lower power level than the set one.
  • the phase angles are adjusted so that a co-directional magnetic field results in the cooking vessel, which at least partially covers both inductors. It is preferable for at least two of the inductors of the inductor group to be adjusted by half a wavelength shifted phase positions in order to increase the energy input into a cooking vessel at least partially covering the two inductors. It is also preferable for opposite directions of flow of the inductor currents to be set for at least two of the inductors of the inductor group in order to increase the energy input into a cooking vessel which at least partially covers the two inductors.
  • the definition that the local orientation of the magnetic fields, in particular in the border region of two or more adjacent inductors and / or in the cooking vessel bottom, is meant for the terms “in the same direction” and "in opposite directions”.
  • two magnetic fields aligned in the same direction result in the boundary region between the inductors a significantly higher energy input into a cooking vessel above it than in the case of oppositely oriented magnetic fields.
  • At least one further phase position is preferably taken into account when setting the phase position of the inductor current.
  • the phase position of at least one adjacent inductor of the inductor group is taken into account.
  • Such a consideration is particularly advantageous when an inductor adjacent to two or three or more inductors. Then, for example, one of the inductors for changing the phase position can be selectively selected without the magnetic fields of the other inductors being adversely affected.
  • the two or three or more inductors prefferably be selected in a targeted manner and their phase positions to be adjusted, so that a favorable combination of magnetic field alignments is obtained, which enables optimal energy input into the overlapping cooking vessels.
  • the phase positions of the inductors are constantly monitored and registered.
  • phase position of at least one inductor of the inductor group it is also possible to prioritize the phase position of at least one inductor of the inductor group.
  • the already existing phase position can be changed or maintained when setting the phase position.
  • the phase position of at least one other inductor of the inductor group is set.
  • the primary inductor can be determined by a control device of the cooking field device. But it is also possible that a specification of the user is taken into account. For example, the user may prioritize a particular performance level. The user may also directly designate one or more cooking vessels as a priority.
  • the power levels predetermined by the user for the two cooking vessels are compared with each other.
  • a control device may be provided.
  • the energy input is adjusted in dependence on a measure of the deviation of the power levels from each other. For example, no adjustment of the energy input is necessary for the same or correspondingly similar power levels.
  • the more the energy input is adjusted the more the given power levels deviate from one another.
  • the energy input for the cooking vessels is adapted, in which there is a particularly large deviation of the power levels.
  • the measure of the deviation of the power levels can be taken into account. For example, one or more inductors can be prioritized depending on the deviation for the setting phase position.
  • the inductor power of the third inductor of the inductor group be readjusted in the sense of power control.
  • the third inductor of the inductor group is in particular that which is covered by at least two cooking vessels.
  • Such a readjustment is advantageous because the multi-covered inductor can not be operated simultaneously with two different power levels. For example, it is possible to average the power levels for both cooking vessels. Subsequently, the inductor power can be adjusted according to the averaged power level. Alternatively, a priority for a cooking vessel is possible in which the inductor power is set according to the priority power level.
  • the readjustment takes place, in particular, before the adaptation of the energy input by the polarity reversal.
  • the inductor power is readjusted as a function of a measure of the deviation of the power levels specified by the user.
  • the readjustment of the inductor power is thus provided in particular in addition to the adaptation of the energy input by changing the phase position. It is also possible to provide a power control independently of the adaptation of the energy input by changing the phase position.
  • the cooking field device has at least one hob with a plurality of inductors for heating to a working area of the hob parked cooking vessel.
  • At least one control device is provided for regulating an inductor output as a function of a power level specified by the user.
  • at least one phase influencing device is provided.
  • the Phase influencing means is adapted and adapted to adjust a phase position of an inductor current of at least one of the inductors.
  • the phase influencing device is also suitable and designed to set the phase position as a function of a multiple coverage of at least one inductor registered by a recognition device by at least two cooking vessels.
  • a phase position of an inductor current of at least one of the inductors is adjusted by the at least one phase influencing device relative to a phase position of at least one adjacent inductor.
  • the phase influencing device an energy input into at least one of the two cooking vessels can be adapted for a given inductor power stage.
  • the cooking field device has the advantage that the energy input into a cooking vessel can be adjusted by targeted modification of the phase position of the inductor.
  • Such an adaptation of the energy input is particularly important when an inductor is covered by two cooking vessels, for which different power levels are given. Since the multiply-covered inductor can provide only one power for both cooking vessels, the phase-influencing device therefore offers a very advantageous possibility of being able to regulate the power supply better.
  • the phase influencing device can change the phase of the magnetic field alignments of the multiply-covered inductor and / or the adjacent inductors and / or other inductors of the cooking field device by adjusting the phase position. Depending on whether same-directional or opposing magnetic fields are set, a different energy input results in the boundary regions between the inductors.
