DESCRIPTION

Cooking system and procedure to manage it

The present invention relates to a cooking system and a method for operating such a cooking system. The cooking system includes at least one cooktop set, at least one cooking utensil and at least one evaluation set, the cooktop set having at least one placement surface for placing cooking utensils and at least two induction devices for heating the cooking utensil placed on the placement surface. The cooking utensil is suitable and configured to be heated by at least one induction device. Furthermore, induction devices of the cooktop equipment have at least respective emitter devices associated with them and the cooking utensil includes at least one receiving device. In this regard, the sending devices send, at least at some times, in each case at least one association signal, which is received by the receiving device of the cooking utensil when the cooking utensil is heated by the corresponding induction device.

Automation of cooking processes and user support is increasingly important in modern home appliances. An increasingly important role is also assigned to driving comfort.

In the field of cooktops, for example, surface-mounted induction cooktops have become known that do not include any fixed cooking zone that is prescribed and unambiguously marked on the mounting surface of the cooktop. The cooking zones or the induction coils located under a placed cooking container are then defined in each case as a cooking zone, only the corresponding induction coils being activated.

In this regard, it is advantageous, if not even necessary, for the cooktop to automatically detect where a cooking container is located, to activate the corresponding induction coils. For this, various systems have been made known. For example, document DE 10 2009 029 253 A1 shows a system in which electrical energy is transmitted inductively to a device located above. The electrical energy thus transmitted is transformed in the device placed above into heat by means of a heating element. The induction coils for transmitting electrical energy can also emit signals, which are then recognized and processed by the cooking container placed above.

But detection of the coverage of several induction coils is only achieved with an expensive design. Furthermore, it is difficult to represent the exact partial coverage of induction coils.

It is therefore the objective of the present invention to provide an alternative automatic association of a cooking container or the like to one or more induction coils of a cooktop, preferably also detecting the percentage coverage of individual induction coils.

This objective is achieved by a method with the characteristics of claim 1 and by a cooking system with the characteristics of claim 20. Preferred developments of the invention are the subject of the dependent claims. Other advantages and characteristics of the invention result from the embodiment examples.

The method according to the invention is suitable for operating a cooking system including at least one cooktop equipment, at least one cooking utensil and at least one evaluation equipment. In this regard, the cooktop device has at least one location surface for placing cooking utensils and at least one generating device with at least two induction devices for heating the cooking utensil placed on the location surface. The cooking utensil is suitable and configured to be heated by at least one induction device. Furthermore, at least one sending device is associated with each of the induction devices of the cooktop equipment, and the cooking utensil includes at least one receiving device. The emitting devices send, at least at some times, in each case at least one association signal, which is received in the receiving device of the cooking utensil, when it is heated by the corresponding induction device. According to the invention, the association signals of the different emitting devices are emitted with a predetermined delay in time, with which the evaluation equipment can associate the association signals captured by the receiving device to the different induction devices and can thus making an association of the cooking utensil to at least one induction device. Additionally or alternatively, the association signals of the different induction devices may include different predetermined sequences of electromagnetic activations as a signature.

A cooking utensil does not necessarily have to exist in the form of a container to house food to be cooked. Also a target that can be heated by the induction coil of the cooktop, for example an immersion kettle, is a cooking utensil within the meaning of the present invention. The configuration of such a target or immersion kettle can be taken from document DE 102014111817 A1, to which we expressly refer here.

The evaluation equipment is in particular in contact or in operative connection with the cooktop equipment and/or the cooking utensil, the evaluation equipment may preferably be part of the cooktop equipment or may be integrated in the same. Depending on the configuration variant, however, the titrating device may also be associated with the cooking utensil or preferably be provided as a separate device, which is connected to the cooking utensil and/or the hob equipment. Thus, for example, the function of the evaluation device can also be provided by a central control device for several home devices, which can be separate from a home device or integrated into a home device. In order for the evaluation unit to process the association signals received by the cooking utensil, the cooking utensil preferably includes at least one communication device, by means of which information and/or the association signals received can be retransmitted to the evaluation unit. assessment. Such communication equipment can be implemented, for example, by Bluetooth, WLAN, radio or the like, or may include such communication means.

The generating equipment includes induction devices, each of which preferably includes at least one induction coil, by which the cooking utensil can be activated or heated. The generating set may preferably also include other power electronics components and/or be connected to them. The process according to the invention offers many advantages. A considerable advantage is that automatic detection of the position of the cooking container and/or the position of cooking utensils on the hob equipment or on the mounting surface of the equipment can be provided by the method according to the invention. of kitchen plate. This way it can be detected which induction devices or which induction coils are covered by a cooking utensil.

It is particularly advantageous that by means of the time-delayed transmission of the association signal, a possibility of associating the association signals with a certain induction device is achieved. Thus, a specific association can be made to a certain coil also with the same association signal and/or with the same signal components by means of time offset.

Furthermore, it is also possible to detect that a cooking utensil is not only located on an induction coil or is activated by an induction coil, but that, for example, a cooking utensil covers several induction coils only partially or even completely. Thus it is also possible to detect the use of several induction devices or induction coils for a cooking utensil.

All of these advantages also result when the induction coils or induction devices emit predetermined signal sequences as a signature, which are unique for each induction device, from which the coverage of certain induction devices can be deduced.

Preferably, the association signals of the different induction devices include the same predetermined sequences of electromagnetic activations, which are differentiated by time offset. By such signals, for example ping signals, a simple association signal can be provided. In this regard, such an electromagnetic activation or such a ping signal can preferably be provided by at least one zone of the electromagnetic activation of an induction device, using a certain segment or zone or value of the half-waves used for the activation as a signal.

When the association signals of the various induction devices include different predetermined sequences of electromagnetic activations as a signature, an unambiguous association to a coil can preferably be found by the type of electromagnetic signal of the individual coils. The number of electromagnetic signals or the number of ping signals and also the distance of the ping signals can then be used as a differentiating characteristic for predetermined sequences of electromagnetic activations. Also in different signal sequences for the different induction devices, it can be achieved by time offset that the signals of the different coils do not overlap and can be evaluated separately.

Preferably, at least two generating devices are provided and the association signals of the various induction devices include in each case a predetermined sequence of at least three electromagnetic activations as a signature. Then it encodes the first distance of the first electromagnetic activation with respect to the second electromagnetic activation the generating equipment of the corresponding activation device and a second distance of the second electromagnetic activation with respect to the third electromagnetic activation encodes the corresponding induction device of the corresponding generating equipment or a the reverse. Thus, an unambiguous association of the various induction devices can also be achieved in a cooktop unit with several generators. The signal sequence contains information about the corresponding generating set and the corresponding induction device.

Preferably, the first distance from one generating set to another generating set is greater and the second distance from one induction device to another induction device of a corresponding generating set is smaller.

By means of such a system of signal signatures, a particularly advantageous and exact, as well as unmistakable, coding of the individual induction devices can be realized, even with coverage of several induction devices.

In advantageous configuration variants, the received electromagnetic activations are converted into a unique identification number, which corresponds to the coverage of certain induction devices. Since the ping signature is converted into a specific and unique identification number for the coverage of induction devices, information transmission can be achieved with a very small data volume.

In the conversion of ping signals or electromagnetic activations, an identification number can be used, for example and preferably with the binary addition method, to convert the presence of signals or the absence of signals into a specific number. The resulting identification numbers are unique for a given signature or combination of signatures. In configuration variants, these identification numbers can be stored, for example, in a list, with a consecutive number, for example a two-position number, being associated with a certain identification number, for example with eight positions.

The complete data processing is preferably carried out on a chip in the cooking utensil. For example, a table of the various identification numbers with a matching list for two-position numbers can be stored on this chip. Thus a transmission of information from cooking utensil to cooktop can be carried out with extremely little data. This can be done, for example, via Bluetooth or another suitable data interface.

With particular preference, the received predetermined sequences of electromagnetic activations of the corresponding induction devices are recorded in a common curve as a function of time, the identification number being determined based on the signal pattern resulting from this. The received signals are then brought, regardless of belonging to a certain induction device, into a total context with all received signals. Then, since the various signatures are unique depending on the configuration, a unique composition of signatures results again, which can be converted into a certain identification number for the corresponding combination of certain induction devices or also individual induction devices.

In convenient refinements, the intensity of at least one association signal is taken into account. In this regard, intensity is understood to mean in particular the amplitude of electromagnetic radiation or of the electromagnetic signal measured by the receiving device. Thus, for a predetermined maximum amplitude, complete coverage of the corresponding induction device can be deduced. For smaller amplitudes, the corresponding induction devices depending on the amplitude are only partially covered.

In convenient configuration variants, the intensity of the association signals is taken into account to deduce the degree of coverage of different induction devices by a cooking utensil. Thus, it is possible to detect by means of the received association signals the induction devices relevant for a cooking utensil placed on top and by means of the intensity or amplitude of the association signal a percentage coverage of the various induction devices or the various coils can be detected. induction. Thus, the coverage of a coil by a cooking utensil can be deduced by receiving a signal, as well as by the amplitude, the magnitude of the coverage.

According to the invention, at least one emitting device is provided by means of at least one induction device. In such a configuration, in particular at least one induction coil of at least one induction device is used as the emitting device. By using an induction coil or a primary coil as the emitting device, an emitting device is provided without great design cost.

Particularly preferably, at least one receiving device includes at least one coil. Such a particular coil may then be arranged at the bottom of the cooking utensil. By configuring the receiving device as a coil or as a secondary coil, a simple technical embodiment of a receiving device is achieved.

In expedient developments, at least two receiving devices are provided on the cooking utensil. Then either two separate receiving devices or only one receiving device with two receivers can be provided, whereby the signals from both receivers can then preferably be evaluated differently or separately. By providing two separate receiving devices or at least two receivers that can be evaluated separately, it is possible to detect the orientation of the cooking utensil as well as movements of the cooking utensil on the mounting surface, it being possible to detect the translational movement of the utensil. for cooking on the surface even with only one receiving device.

Preferably at least one orientation of the cooking utensil on the mounting surface is detected. This is possible in particular when at least two receiving devices are provided on the cooking utensil.

When covering two or more induction devices by the cooking utensil, at least one operating parameter of at least one induction device is preferably adjusted in particular as a function of the orientation of the cooking utensil. Two different cooking zones can then be provided, for example in a roasting utensil, by providing two receiving devices, for example at the bottom of the roasting utensil. Thus, for example, it can be detected by both receiving devices which of the two coils is oriented in the direction of the user. Thus, in a preferred configuration variant of a special cooking utensil, it can be achieved, for example, that for a certain orientation of the cooking utensil on the hob equipment, a hot zone for frying can be provided in front and a somewhat colder zone behind. heat maintenance. If the cooking container is placed in a different orientation on the cooktop, provision can be made, for example, for uniform heating of the cooking utensil. The applicant entity reserves the right to also claim a cooking vessel with at least two receiving devices.

Preferably at least one movement of the cooking utensil on the mounting surface is detected. The movement of the cooking utensil on the mounting surface can be detected both with a coil and also with various receiving devices on the cooking utensil.

Preferably the movement of the cooking utensil on the mounting surface includes at least one translational movement and/or at least one turning movement. Thus, it can be detected, for example, if the cooking utensil is removed from an initial position and/or if the cooking utensil is rotated about the initial position. Using both actions, certain operating parameters can be modified or adjusted depending on the configuration variant. A rotating movement is preferably detected in a cooking utensil that includes two receiving devices.

Preferably at least one operating parameter of the cooktop equipment is adjusted based on the movement. Thus, for example, by removing a cooking utensil from the induction device currently used, an automatic shutdown of the cooktop equipment at least for that cooking utensil can be caused. Furthermore, it is possible, for example, that by rotating the cooking utensil in its position, the power of the corresponding induction device varies. For example, the power can be increased, depending on the configuration variant, by turning clockwise, causing a reduction in power by turning counterclockwise.

Preferably at least one operating parameter of at least one induction device set for a cooking utensil is transmitted when moving the cooking utensil to the then relevant induction device(s). Thus, by moving the cooking vessel on the mounting surface, the setting for a cooking utensil can be transmitted to another induction device, when the cooking vessel is, for example, moved to another location due to lack of space or for other reasons. .

Preferably, the emitting devices send the association signals during the operation of at least one induction device. In such a configuration variant, for example, the electromagnetic radiation used to heat the cooking utensil or areas thereof can also be used as an association signal. In other convenient configuration variants, or also in addition, the transmitting devices send the association signals also when the hob equipment or the induction devices are not operating. Such a method operates in particular with relatively low electromagnetic radiation, where a position of the cooking container can also be detected when the hob equipment is switched off or when no induction device is operating.

Preferably, an indicator device on the cooking utensil is activated by the association signals and/or a variation of the association signals. This can facilitate, for example, the visualization of parameters or instructions to the user and/or monitoring of a cooking process. The applicant entity reserves the right to also claim such a cooking utensil.

The cooktop system according to the invention includes at least one cooktop equipment, at least one cooking utensil and at least one evaluation equipment, the cooktop equipment including at least one placement surface for placing cooking utensils and at least two induction devices for heating the cooking utensil placed on the placement surface. The cooking utensil is suitable and configured to be heated by at least one induction device. The induction devices of the cooktop equipment are associated with at least respective emitting devices, the cooking utensil including at least one receiving device. The emitting devices are suitable and configured to emit, at least at some times, in each case at least one association signal, the receiving device being suitable and configured to receive these signals when the cooking utensil is heated by the corresponding device. induction. According to the invention, the evaluation equipment is suitable and configured to carry out an association of the cooking utensil to at least one induction device by means of the association signals sent by the emitting device with a delay in time and captured by the receiving device and/or through the signatures captured from the predetermined sequences of electromagnetic activations of the different association signals of the different induction devices.

The cooking system according to the invention also offers the advantages already described above in relation to the method according to the invention.

Preferably, at least one emitting device is provided by means of at least one induction device or at least one induction coil of the at least one induction device. Thus, at least one emitting device is provided, preferably by means of at least one primary coil.

Particularly preferably, at least one receiving device includes at least one coil or at least one secondary coil.

In convenient configuration variants, at least two receiving devices are provided on a cooking utensil. Then preferably two separate receiver devices and/or a receiver device with at least two receivers that can be evaluated separately are provided.

In convenient configuration variants, the cooking utensil includes at least one display device, which in particular can be activated or supplied with information by means of at least one association signal and/or at least one variation of the association signal.

In Figure 1, a cooking system 200 according to the invention is represented purely schematically in a perspective view. In this regard, the cooking system 200 includes, in an exemplary embodiment shown here, a cooking plate unit 1, which is housed in the countertop 301 of a kitchen row 300.

The cooktop equipment 100 includes a storage surface 2, on which cooking utensils 100 can be placed. Below the storage surface 2, in the exemplary embodiment shown here, several induction devices 3, here uniformly arranged. , by means of which the cooking utensil 100 placed on the placement surface 2 can be heated. Only two induction devices 3 are shown here in Figure 1, for greater clarity of the assembly.

Furthermore, the cooking system 200 includes an evaluation device 50, which in the exemplary embodiment shown here is integrated into the cooking plate device 1.

The kitchen hob equipment 1 includes in the exemplary embodiment shown here several emitting devices 4, for sending at least one association signal 5, by means of which, by interacting with the cooking utensil 100 and the evaluation equipment 50, it can be detected automatically the position of the cooking utensil 100 on the placement surface 2. It is thus possible to associate the induction devices 3 with a cooking utensil 100 placed on the placement surface 2.

The emitting devices 4 are then, in the exemplary embodiment shown here, integrated into the induction devices 3 or are provided by the induction coils of the induction devices 3.

The cooking utensil 100 here has a receiving device 101, which in the shown embodiment is also provided by a coil 102 on it or on the bottom 104 of the cooking utensil 100. Depending on the configuration variant, they may also be more than one receiving device 101 and/or several receivers are provided. In the method according to the invention, the sending devices 4 send, at least at some times, association signals 5, which are received or detected by the receiving device 101 or, depending on the configuration variant, with several receiving devices. 101 of the cooking utensil 100, when the cooking utensil 100 is arranged on the placement surface 2 in such a way that it is heated by these induction devices 3.

The received association signals and/or a signal that has been processed are transmitted by a suitable communication device, not shown in more detail, to the evaluation equipment 50. The communication equipment may then be integrated into the utensil for cooker 100 or, depending on the configuration variant, also be provided as a separate module, which by means of suitable functions can access the receiving device 101 of the cooking utensil 100.

The cooking utensil 100 may also include an indicator device 103, which is activated by the association signals 5, by modifications of the association signals or otherwise. Thus it is also possible to transmit information by means of the association signals to the cooking utensil and display them on the display device 103. Figure 2 represents in a purely schematic manner the operation of the method according to the invention. Four induction devices 3 of a kitchen hob unit 1 are represented, the induction coils of the induction devices 3 functioning as emitter devices 4.

Below the induction devices 3, the half waves sent by the induction devices 3 or the induction coils of the induction devices 3 to heat a cooking utensil 100 are indicated in Figure 2. In addition to the induction devices, the It represents in a purely schematic way that an area of these half-waves or a certain value of the voltage of the electromagnetic radiation is used as an association signal 5.

Below the series of half-waves two examples of association signals 5 for the induction devices 3 are shown. It is shown in the first rows 1-4 that the four induction devices 3 or the four emitting devices 4 emit a signal of association 5 staggered in time, the pattern of association signals being identical. The so-called ping signals are provided here, including an emission pattern of three signals with a certain time offset.

By means of the time offset when transmitting the association signals 5, however, an unambiguous differentiation between the various induction devices 3 can be achieved. In the embodiment shown here, the time offset is about 10 ms. However, the time offset can also be chosen in other suitable ranges. In the four lower rows it is shown, purely schematically, that the association signals 5, which are now also provided as ping signals, do not have the same structure.

Thus, a signal structure is formed here, through the distance between the different signals of the different emitting devices, which is different and unambiguous for each induction device.

Thus, only through the structure of the association signals or the ping signals, it can be deduced that it is a certain induction device 3 or a certain emitting device 4.

Due to the time offset of the emission of the association signals 5, the joint detection of various signals does not occur, so that by means of the time component the signal of different induction devices 3 or emitting devices can always be unequivocally differentiated. 4.

In Figures 3 and 4, the association signals 5 received in a cooking utensil are represented in a purely schematic manner, covering only the first induction coil 3 in the exemplary embodiment shown here, a cooking utensil 100. The signal received and evaluated in the evaluation device 50 corresponds to the signal structure and the time component of the first induction device 3. Thus the position of the cooking utensil 100 on the location surface 2 can be deduced unambiguously.

In Figure 4 it is shown that the cooking utensil 100 is located on the first and third induction devices 3. The corresponding signal is shown on the right side, and an association to certain induction devices 3 can be unequivocally found by means of the structure of signals and the reception in time of the corresponding association signals 5 by the receiving device 101, whereby the exact position of the cooking utensil 100 on the location surface 2 is detected by means of the evaluation equipment 50. In the figures 5 and 6, a possibility of differentiating the association signals 5 of more than four induction devices 3 or the induction devices of several generators is represented in a purely schematic manner. In this regard, the induction devices 3 are divided into 2 groups of four, the differentiation being made between the first and the second group by means of a phase offset. This has been achieved in this case between the induction devices 3 of a first generator A and those of a second generator B by means of a phase offset of 120°.

In Figure 5, two induction devices 3 are covered by a cooking utensil 3. The association signals 5 received by the receiving device 101 of the cooking utensil 100 and transmitted to the evaluation device 50 are represented next to the induction devices 3 .

In Figure 6, the same configuration as in Figure 5 is again represented, now covering the cooking utensil 100 placed on top of four induction devices 3. The data or signals received by the receiving device 101 of the cooking utensil are again represented. 100 and transmitted to the evaluation team 50.

Figures 7 to 9 show in a purely schematic manner that the amplitude or intensity of the received association signal 5 can contribute to optimizing position detection.

In this regard, it is shown in Figure 7 that a cooking utensil 100 is predominantly located on the first induction device 3. Only a significantly smaller part of the cooking utensil 100 also covers the second induction device 3.

The percentage coverage of induction devices 3 by a cooking utensil 100 can be determined unequivocally by the magnitude or amplitude or intensity of the association signals 5 received. The association signal 5 received from the first induction device 3 is considerably larger than that of the second induction devices 3. Thus, the percentage coverage of the corresponding induction device can be deduced by a magnitude or amplitude or intensity received from an association signal 5 which corresponds to the degree of coverage of an induction device 3.

In Figure 8 the same configuration is again shown as in Figure 7, the first two induction devices 3 being uniformly covered by a cooking utensil 100. The corresponding association signal 5 is shown next to it, here indicating the same amplitude. or signal magnitude of the association signals 5 a coverage of approximately 50% in each case of the respective induction devices 3.

Figure 9 shows, as before in both figures, that the percentage coverage can be deduced from the magnitude or amplitude or intensity of an association signal 5. Here the first four induction devices 3 are covered in different magnitude by a cooking utensil 100, the first and the second induction devices 3 being covered in the same magnitude and the third and the fourth induction devices 3 such that the first and the second induction devices are covered to a greater extent than the third and fourth. The corresponding received association signals 5 are shown on the right side.

10 shows purely schematically that a cooking utensil 100 can also have more than one receiving device 101. Then, in addition to the position on the location surface 2 of a cooktop device 1, it can also be detected. the orientation of the cooking utensil 100 on the placement surface 2.

There, it is indicated purely schematically by the arrow in which orientation the cooking utensil 100 is located on the mounting surface 2. The cooking utensil 100 is represented purely schematically again in the center, to again represent both devices. receivers 101.

Thus, for example depending on the configuration variant, a different type of service can be associated with different zones or segments of a cooking utensil 100. For this purpose, different cooking zones are provided here depending on the orientation of the cooking utensil 100 on the storage surface 2 or depending on which receiving device 101 is facing towards the user or away from it.

For example, in the left representation it is possible that in front of or facing the user, another zone for frying is provided, with a heat preservation zone being provided in the rear zone of the cooking utensil 100.

If the cooking utensil 100 is now placed in a different orientation, in the exemplary embodiment shown here rotated by 180°, for example, uniform heating of the cooking utensil 100 can be provided.

11 shows purely schematically that by moving the cooking utensil 100 on the mounting surface 2 of a cooktop unit 1, certain operating parameters can be adjusted, for example. This is possible both with only one receiving device 101 and also with several receiving devices 101.

If, for example, only one receiving device 101 is provided on the cooking utensil 100, translational movements can be detected and converted into control signals, for example. Thus it is possible that, for example, by removing a cooking utensil 100 from an induction device 3, this induction device 3 is switched off. Furthermore, it is possible, depending on the configuration variant, to transmit the operating parameters set for a device induction device 3, by removing the cooking utensil 100 to another induction device 3, to said induction device 3.

In particular, when at least two receiving devices 101 are provided, rotational movements on the mounting surface 2 can also be detected, whereby, for example, by rotating the cooking utensil 100, operating parameters are modified. Thus, for example, by turning the cooking utensil 100 clockwise, the power can be increased, while the power can be reduced by turning counterclockwise. Other adjustments can also conveniently be made by the movement and/or orientation of the cooking utensil.

Figure 12 shows in a purely schematic manner that, in particular when several generating devices 6, 7, 8 are used, the association signals 5 can not only be sent time-delayed with respect to each other, but additionally or also exclusively can have a certain signal signature or ping signature. In the exemplary embodiment shown here, a first generator 6 with four induction devices 3 or induction coils, a second generator 7 with four induction devices 3 and a third generator with four induction devices 3 are provided.

To enable unambiguous association of a cooking utensil 100 with one or more induction devices 3, both time-delayed association signals 5 and signal signatures are used in the exemplary embodiment shown here.

In this regard it can be seen that a signal time curve of 23 signal blocks 12 is used here, one signal block here corresponding to 10 ms. An association signal 5 may or may not be sent and/or received in each signal block.

In order to differentiate the various induction devices 3 of the various generators, a defined signal structure is used in the illustrated embodiment. In this regard, each induction device sends a predetermined sequence of electromagnetic activations as a signature, the signal sequences of the induction devices 3 of each generating unit 6, 7, 8 being sent staggered in time. The signal sequences are then started one signal block later in each case.

The predetermined sequence of electromagnetic activations as a signature has, in the example embodiment shown here, three activations, defining a first distance 9 between the first activation and the second activation of the generating equipment 6, 7, 8. This first distance 9 increases here from the first generating device 6 to the third generating device 8. Thus, it can be deduced by the first distance 9 between the first activation and the second activation of a signal sequence, that it is the corresponding generating device 6, 7, 8.

A second signal 10 defines the corresponding induction device 3, which for greater clarity of the assembly is designated according to its belonging to a certain generating equipment 6, 7, 8 with A1, A2, A3, A4, B1 [...] C3 and C4. Then the distance 10 is reduced from the induction device A1 to A4, B1 to B4 and C1 to C4.

By means of this system in the sequence of signals, an unambiguous association of a cooking utensil 100 can be made to certain induction devices.

Figures 13 and 14 represent the other processing of the given signal sequences or signatures. In this regard, the signals determined in the shown embodiment, regardless of their belonging to a certain signal sequence of a certain induction device 3, are recorded in the signal blocks 12 provided here 23.

Through the corresponding systematics of the signal sequences based on the signal offset and the distances 9, 10 between the signals, here again unambiguous patterns result, which correspond to the coverage of certain induction devices. In this regard, only multiple coverages have been taken into account in Figures 13 and 14.

The signal pattern thus recorded is here converted into an eight-position number or identification number 11 by binary addition. Other methods can also be used to convert the pattern into a unique number. This identification number 11 corresponds to a certain covering of induction devices 3 by a cooking utensil 100.

This identification number 11 could be transmitted to the cooktop without too large a volume of data. However, in the exemplary embodiment shown here, a table is stored on a chip in the cooking utensil 100, in which a correlative number is associated with each identification number 11, which in Figures 13 and 14 is inscribed on the digit next to the identification number 11. This can again reduce the data volume in the transmission from the cooking utensil 100 to the cooktop 1.
