Definitions
- the invention relates to a method for controlling an induction hob as well as an induction hob suitable for carrying out this method.
- the invention has for its object to provide an aforementioned method for controlling an induction cooktop and a corresponding induction cooktop with which problems of the prior art can be solved and it is particularly possible to achieve energy efficiency at high or very high power densities for induction heating coils to improve joint heating of a cooking vessel in the composite.
- the induction hob according to the invention comprises a cooktop plate and including a number of induction heating coils, which can be controlled individually and in a common composite.
- such an induction hob according to the aforementioned WO 2010/084096 A2 be formed, alternatively also according to the EP 2945463 A1 or the EP 3026981 A1 ,
- a placed cooking vessel defines with its base a cooking point.
- Those induction heating coils which are at least partially covered by the cooking area, are controlled for the common heating of the cooking vessel in the composite. So they are switched on and off together.
- they are operated with the same power level or power, so advantageously with the same power density, which is to be understood here as surface power density.
- a difference in the power density can advantageously be at most 15%, advantageously at most 10%.
- a first operating case which is defined as operation with a very high power density, advantageous as operation with a maximum power density, at least in that one exactly Indutationswespule the common composite, which has the least coverage by the cooking or the cooking vessel, the frequency increased their control. So it is at least one induction heating coil taken for the frequency increase, and that at least exactly one induction heating coil, which has the least coverage by the cooking or the cooking vessel.
- This can be done by a procedure according to the EP 2330866 A2 or the EP 2574144 A2 be determined on the basis of the parameters in the control of the individual induction heating coils or on the basis of the parameters of their vibration response.
- This exactly one induction heating coil then operates at a higher frequency than other induction heating coils or as the remaining induction heating coils of this composite under this cooking point.
- a frequency increase may be at least a few kHz or more than 1 kHz, more preferably more than 10 kHz or more than 17 kHz.
- this least-covered induction heating coil As a result, it is possible for the efficiency of this least-covered induction heating coil to be somewhat improved in its operation by increasing the frequency. It will namely reduced at the same power density of the current, which automatically reduces the losses in this induction heating coil also.
- the inventive method has compared to the aforementioned WO 2010/084096 A2 has the advantage that, as it were, power is coupled into the cooking vessel bottom over the entire area of the cooking zone formed by the installed cooking vessel, or at least over a majority of the area, although this may have a somewhat reduced power density in the area of the induction heating coil or induction heating coils operated at a higher frequency , For an even stronger heating of the cooking vessel is possible and thus, for example, can be achieved even faster that boiling water therein.
- the first operating case may be present when the induction heating coils operate as a composite for a cooking station with a power density of more than 50% of their maximum power density or more than 6W / cm 2 , advantageously at least those induction heating coils of the cooking station not be changed in their frequency.
- this power density may be for the presence of the first operating case in more than 65% of the maximum power density or exceed 7W / cm 2.
- this corresponds to operation with the level 9, ie the highest regular power level, as well as the overlying boost power level, which then defines the maximum power density. This can be about 10 W / cm 2 .
- Such a boost power level should only be used for a short or a few minutes, but usually sufficient, for example, to bring water to a boil as quickly as possible.
- the frequency of those Induzzyswespulen is increased, which are covered to less than 30% of their area from the cooking area.
- the increase in frequency even apply only to those induction heating coils, which are covered to less than 20% of their area from the hob or from the cooking vessel. So these are the aforementioned least covered induction heating coils.
- This definition can thus also be used to determine whether only a single induction heating coil with the lowest coverage is operated at a higher frequency or whether the two induction heating coils or even the three induction heating coils with the lowest coverage are operated at an increased frequency.
- the least covered induction heating coil or the two or even the three in each case least covered induction heating coils are operated at a higher frequency and therefore at a lower power density.
- the current for their control can be slightly reduced again, so that their electrical losses can be lowered again something.
- a second operating case can be defined as operation with a high power density. This is thus slightly lower than the above-described very high power density.
- All operated induction heating coils of the network under the cooking area are controlled so that the power density, which is generated at or below the cooking area, is evenly distributed or that the power density, ie the power generation per area, at each of the induction heating coils operated under this hob.
- those induction heating coils are advantageously operated, which are covered to less than 40% of their area from the cooking area. It is also possible to operate those induction heating coils which are covered to less than 30% or even less than 20% of the cooking surface. Induction heating coils, which are less than 10% covered by the cooking area, are not operated.
- this second operating case the cooking vessel set up on the cooking surface is thus operated with a lower power density than in the first operating case, which, however, is still relatively high.
- the pure efficiency of the power generation is no longer the only decisive factor here, above all, the most uniform possible heat distribution is desired.
- Such a high power density of this second operating case is used, for example, for searing steaks or pancakes, where, in contrast to the fastest possible boiling of water, a uniform heat distribution is advantageous for a desired frying result.
- a power density by which this second operating case is defined may be between 35% of the maximum power density and the power density above which the above-described first operating case exists or the power density may be between 35% and 50% or even 65% of the maximum power density.
- the power density of 4 W / cm 2 to 6 W / cm 2 or even 7W / cm 2 may be.
- the power density can be significantly increased in the above-described second case of operation in those induction heating coils, which have only between 10% and 20% coverage through the hob or the raised cooking vessel.
- their power density can be increased by at least 30%, particularly advantageously by up to 60%.
- the power density in the above-described second case of operation for induction heating coils, which have between 20% and 30% coverage by the cooking or the raised cooking vessel, can be slightly increased as previously described for even less covered induction heating coil. So here, the power density can be increased preferably only by 10% to 30%. However, this is sufficient in view of the slightly higher degree of coverage to achieve the aforementioned goal of a uniformly distributed temperature on the cooking vessel bottom.
- a control of the induction hob is therefore designed to perform the method described above according to the invention and in its various embodiments.
- the aforementioned parameters can be evaluated, which in the aforementioned EP 2330866 A2 or the EP 2574144 A2 are described accordingly.
- the power control means are arranged or designed as half-bridge converters, whereby a desired power density can be generated advantageously and without major losses.
- Each induction heating coil advantageously has its own converter in series resonant circuit technology for activation with its own frequency and individual duty cycle.
- a duty cycle of 50% means that one upper and one lower IGBT of a half-bridge of said half-bridge inverter are each turned on for 50% of a period for the same time, with the maximum current flowing in the induction heating coil at the selected period.
- a duty cycle of 10% means that the first IGBT is only switched on for 10% of the period and the second IGBT for a remaining time, ie 90% of the period Period. It usually applies that the smaller the duty cycle for a given period or frequency, the smaller the current in the induction heating coil and the less power is induced or introduced into the set-up cooking vessel.
- This circuit concept allows multiple induction heating coils to be driven at the same frequency or at a second, higher frequency. This second higher frequency should just be more than the aforementioned 17 kHz above the first frequency to avoid audible interference noise.
- the cup resistance coupled into the induction heating coil increases with the frequency used. Below a minimum coverage, an induction heating coil should not be operated, because then the transmittable power is disproportionately low compared to the electrical losses. In the invention, it should therefore also be possible to operate at high power densities or at very high power densities for a hotplate all Induzzyswespulen having a certain minimum level of coverage. This minimum should be at least 10% overlap, preferably at least 20% or even 30%. Thus, if a total required total power can not yet be achieved, the induction heating coil with the second largest surface coverage is also operated at the first, lower frequency, and this induction heating coil and the induction heating coil having the largest area coverage are operated at a higher output. Then, for these two, the duty cycle can be 50% or nearly 50%.
- these induction heating coils should all be operated at the same frequency and 50% duty cycle.
- the increase in the power density for low-coverage induction heating coils is due to the fact that, with their small coverage, a covered edge region of the induction heating coil, in which this is not effective, in relation to the covered surface of the induction heating coil is especially big.
- a larger unheated area resulting from the spacing or clearance areas or interfaces between the inductors must be balanced.
- FIG. 1 a plan view of a number of induction heating coils in a tight array next to each other, which are arranged under an induction hob.
- a cooking vessel is set up and defines with its footprint a cooking surface.
- a cooking vessel 15 can be heated.
- This arrangement of induction heating coils 13 could be installed in an induction hob 11, so be arranged under a hob plate.
- the above-mentioned WO 2010/084096 A2 directed.
- less or even significantly less induction heating coils could be provided, for example, about twice as large.
- the induction heating coils 13 are partially covered differently. Five induction heating coils 13a are fully covered, recognizable by the cross-hatching. Three induction heating coils 13b are covered to significantly more than 50%. As they are arranged here, coincidence is just at this selected position for the cooking vessel 15 and need not always be so, as well as the arrangement of the five fully covered induction heating coils 13a. Two further induction heating coils 13b in the upper right and left in the middle are covered to about 50%. The induction heating coils 13b are obliquely and narrowly hatched.
- induction heating coils 13c are covered to about 30% or less of their area, and the rightmost induction heating coil 13c is only about 10% in the center. Their arrangement is also random. The induction heating coils 13c are only obliquely and widely hatched.
- induction heating coils 13a For the five fully covered induction heating coils 13a, it will most of all be the case that they are arranged next to one another or, so to speak, as a kind of flat composite.
- the induction heating coils 13b and / or 13c may, however, also be arranged completely opposite such a fully covered composite.
- the degree of their coverage by the cooking vessel 15 can be approximately determined.
- the cooking vessel 15 should be operated with a very high power density, which may be more than 50% or even more than 65% of the maximum power density, that is more than 6W / cm 2 or 7W / cm 2 and usually corresponds to an induction hob of the power level 9 or an overlying boost power level, should be heated as quickly as possible in the cooking vessel 15 as a typical application.
- An unillustrated control of the induction hob 11 for the induction heating coils 13 then just states that the five induction heating coils 13a are fully covered. They are therefore operated with the mentioned very high power density.
- the five induction heating coils 13b which are only partially, but at least 50%, covered by the cooking vessel 15 and the cooking zone 17, are also operated with this very high power density. In particular, they are operated either with the same current as the fully covered induction heating coils 13a. Alternatively, they will be at the same power density how the fully covered induction heating coils operated 13a, but related to the surface of the cover by the cooking vessel 15 and by the hotplate 17. This is because, when such induction heating coil 13b is just over 50% covered, like right upper induction heating coil 13b, all the power generated by it is coupled into the overlying area of the bottom of cooking vessel 15. Thus, in this case, the power density can be related to the area of overlap between cooking vessel 15 and cooking area 17 and induction heating coil 13b.
- the right upper induction heating coil 13b is operated at about half the power density of the induction heating coils 13a, and in its own area, and substantially all of the power is coupled into the overlying area of the bottom of the cooking vessel 15, it results Bottom of the cooking vessel 15 the same power density of the coupled power as over the fully covered induction heating coils 13 a.
- the induction heating coils 13b are operated with the same current and at the same frequency as the fully covered induction heating coils 13a, in the overlying areas of the bottom of the cooking vessel 15, the coupled power density would be twice as high. Although this can also be provided, it does not have to be that way.
- the three less than 30% covered induction heating coils 13c are regarded as the induction heating coils according to the invention with the least coverage by the cooking point 17 or by the cooking vessel 15. Thus, it need not be just a single induction heating coil, for example the induction heating coil 13c at the bottom right, which is considered to be the one with the least coverage and which is then driven at the higher frequency. It is due to the large number of existing induction heating coils 13 and their small size that so many of the cooking vessel 15 and the cooking area 17 are at least partially covered. In the case of these three induction heating coils 13c, the frequency of the activation is thus increased according to the invention, advantageously by at least 17 kHz, particularly advantageously by approximately 20 kHz. Accordingly, the current is reduced, with which they are driven or flows through them.
- Fig. 1 is also easy to imagine, as with other size ratios of induction heating coils 13 and cooking vessel 15 or cooking 17 induction heating coils with different Coverage levels are operated differently according to the inventive idea. So it could be that a cooking vessel 15 with a cooking point 17 formed by him even covered only four induction heating or at least partially extending over this. Then again, it could be that only a single induction heating coil is considered to be the one with the least coverage and operated with a correspondingly increased frequency and current.
- the inventive idea works as well with a smaller number of induction heating coils than according to the embodiment of Fig. 1 ,
- the cooking vessel 15 can be heated with a high power density.
- This high power density can be 35% to 50% of the maximum power density, ie 4W / cm 2 to 6W / cm 2 .
- This usually corresponds to an induction hob of the power level 6 to 8.
- a very high power density and a maximum power density was desired, for example, a steak can be fried or pancakes are prepared in this second case of operation.
- a very high temperature of the bottom of the cooking vessel 15 is desired, especially in the case of a pan over 200 ° C.
- the subsequently required power supply then corresponds only to a high power density.
- the performance of these is low covered induction heating coils 13c even increased beyond a valid for the other induction heating coils power density addition.
- Such an increase may be made by at least 30% with a coverage of between 10% and 20%.
- the other two induction heating coils 13c have an overlap of between 20% and 30% through the cooking vessel 15 or through the hotplate 17.
- the power density is increased by about 10%, so to speak to compensate for the aforementioned interfaces. As a result, as much heat as possible is achieved in the bottom of the cooking vessel 15 in this second operating case.
