    INDUCTION
    DESCRIPTION
    The invention refers to an induction cooking field which comprises at least one cooking field plate, at least a first coil, and at least a second coil, which are relative relative to each other at least in the direction perpendicular to the cooking field plate, and with a control unit, characterized in that the control unit is provided to operate at least temporarily the first coil and the second coil simultaneously and a method for operating the cooking field by induction.
    The use of induction cooking fields comprising at least one cooking field plate and several inductors that are arranged under the cooking field plate is known. In this way, the inductors are arranged in the same plane and spaced apart.
    Also, EP 1 858 300 A1 discloses an induction cooking field comprising a cooking field plate and several inductors of a layer that are relative relative to each other at least in the direction perpendicular to the field plate of cooking, where the inductors are operated alternately.
    The invention solves the technical problem of providing a generic induction cooking field with better characteristics in terms of its efficiency. According to the invention, this technical problem is solved by an induction cooking field, which comprises at least one cooking field plate, at least a first coil, and at least a second coil, which are relatively displaced between if at least in the direction perpendicular to the cooking field plate and, in particular, at least when observed in the direction parallel to the main extension plane of the cooking field plate, and with a control unit, where the unit control is provided to operate at least temporarily the first coil and the second coil simultaneously. The main extension plane of an object refers to a plane that is parallel to the side and / or most extensive face of the smallest imaginary geometric parallelepiped that surrounds the object

    tightly completely, and which preferably runs through the center, in particular, the geometric center, of the parallelepiped.
    The induction cooking field comprises multiple coils and / or inductors, at least four, preferably, at least six, advantageously, at least twelve, more advantageously, at least twenty-four and, more advantageously, at least forty and eight coils and / or inductors. Therefore, the induction cooking field is preferably performed as a matrix cooking field and / or as a flexible cooking field.
    The coil is an inductive element preferably formed by at least one filament, in particular a heating filament, and which is advantageously part of an inductor. The coil comprises at least one turn and, preferably, several turns as at least two, at least five, at least ten and / or at least fifteen turns, arranged in one layer and / or preferably in several layers.
    Advantageously, the coil is intended to generate an alternating electromagnetic field that is transformed into heat at the base of a cooking drum by eddy currents and / or magnetization and demagnetization effects. Particularly advantageously, the first coil and the second coil comprise the same diameter, and preferably are at least essentially identical. The diameter of an object is the diameter of the smallest imaginary circuit that completely envelops the object. The term "essentially identical" refers to identities regardless of manufacturing tolerances and / or within the limits of standardized tolerances and / or the limits of production possibilities.
    The control unit is an electrical and / or electronic unit that is intended to control and / or regulate the operation of the induction cooking field and / or of at least one construction subgroup of the induction cooking field. For this purpose, the control unit preferably comprises a processing unit, a memory unit and / or an operating program that is advantageously stored in the memory unit and preferably executed by the processing unit. In addition, the induction cooking field may comprise at least one power supply unit, which is intended to supply power to at least one of the coils, and / or at least one retention unit, which comprises at least one retention element that is intended to retain and / or support at least one of the coils.

    and / or a support built specifically. By performing according to the invention, an induction cooking field with better characteristics can be obtained in terms of its efficiency, in particular, the efficiency of the power, the efficiency relative to the installation space, the efficiency of the components and / or cost efficiency Additionally, it is possible to advantageously increase flexibility. In this way, the distribution and / or arrangement of the coils can be improved, which leads to a particularly uniform distribution of power, thanks to which an advantageous thermal distribution can be achieved at the base of a cooking drum. Likewise, a better resolution of the coverage can be obtained with respect to a cooking drum placed on the cooking field plate, whereby flexibility can be increased to a greater extent.
    Preferably, the first coil and the second coil are displaced considerably relative to each other at least in the direction parallel to the cooking field plate and / or at least when observed in the direction perpendicular to the main extension plane of the cooking field plate. The expression that an object is "displaced considerably" with respect to another object at least in the direction parallel to the cooking field plate refers to the maximum 85%, advantageously, 80% maximum and , more advantageously, a maximum of 75% of all lines leaving the object and perpendicular to the main extension plane of the cooking field plate run through the other object, preferably, the second coil is arranged with respect to the first coil so that the center, in particular, the geometric center, of the second coil is distanced from the outer limit of the first coil at least when observed in the direction perpendicular to the main extension plane of the cooking field plate In this way, the distribution and / or arrangement of the coils can be optimized.
    Likewise, it is proposed that the first coil and the second coil overlap partially or completely at least in the direction perpendicular to the cooking field plate and / or at least when observed in the direction perpendicular to the main extension plane of the plate of cooking field. Particularly advantageously, the overlapping area between the first coil and the second coil amounts to 5% minimum, preferably 10% minimum and, most preferably, 15% minimum, and 45% maximum. , preferably, at a maximum of 40% and, more preferably, at a maximum of 35%, of the total surface area of the first coil or the second coil, at least when observed in the direction perpendicular to the main extension plane of the plate of cooking field.

    shape, the distance between the centers of the coils can be reduced and / or the diameter of the inductor can be increased, in particular, by a factor of 1.77, while the distance between the centers can be kept constant.
    Likewise, it is proposed that the first coil and the second coil be arranged directly adjacent to each other. The expression that two coils are "directly adjacent" refers to no other coil being placed between the two coils. As a result, a particularly compact induction cooking field can be obtained.
    In accordance with the invention, it is proposed that the first coil and the second coil be electrically connected in parallel or in series and, preferably, by an electric cable or a track, in particular in the case where plate retention elements are used Printed circuit In this way, it is possible to simplify a control algorithm advantageously.
    In a preferred embodiment of the invention, it is proposed that the induction cooking field comprises at least a third coil that is displaced with respect to the first coil and the second coil at least in the direction perpendicular to the field plate of cooking and, in particular, at least when observed in the direction parallel to the main extension plane of the cooking field plate, where the control unit is provided to operate at least temporarily the third coil simultaneously with the first coil and The second coil. Advantageously, the third coil and the first coil and / or the third coil and the second coil comprise the same diameter, and preferably, are at least essentially identical. Particularly advantageously, the third coil is arranged directly adjacent to the first coil and / or the second coil. As a result, the resolution of the coverage can be increased to a greater extent, whereby a particularly uniform power distribution can be achieved.
    Likewise, it is proposed that the third coil be displaced considerably with respect to the first coil and / or the second coil at least in the direction parallel to the cooking field plate and / or at least when observed in the direction perpendicular to the plane of main extension of the cooking field plate. Preferably, the third coil is arranged with respect to the first coil and the second coil in such a way that the center, in particular, the geometric center, of the third coil is distanced from the outer limit of the first coil and the second coil at least when observed in the direction perpendicular to the main extension plane of the

    cooking field plate. In this way, the distribution and / or arrangement of the coils can be further optimized.
    A particularly compact induction cooking range can be obtained if the third coil and the first coil and / or the third coil and the second coil overlap partially or completely at least in the direction perpendicular to the cooking field plate and / or at least when observed in the direction perpendicular to the main extension plane of the cooking field plate. Advantageously, the area of overlap between the third coil and the first coil amounts to 5% minimum, and 45% maximum, of the total surface area of the third coil or the first coil, at least when observed in the direction perpendicular to the main extension plane of the cooking field plate. Also, the area of overlap between the third coil and the second coil amounts to 5% minimum and 45% maximum, of the total surface area of the third coil or the second coil, at least when observed in the direction perpendicular to the plane main extension of the cooking field plate.
    Additionally, it is proposed that the third coil and the first coil and / or the third coil and the second coil be electrically connected in parallel or in series and, preferably, by an electric cable or a path, in particular in the case use printed circuit board retention elements, whereby it is possible to advantageously simplify a control algorithm. Thus, the first coil, the second coil, and the third coil are advantageously electrically connected in parallel and / or in series and, preferably, by an electric cable and / or a track, in particular in the case that printed circuit board retention elements are used.
    In one embodiment, it is proposed that the first coil and the second coil form partially or completely, preferably, largely or completely, and more preferably, completely, an inductor. Particularly advantageously, the first coil, the second coil, and the third coil form partially or completely, preferably, largely or completely and, more preferably, completely an inductor. The expression "largely or completely" refers to that in a percentage of 55% minimum, advantageously, 65% minimum, preferably 75% minimum, most preferably 85 % as minimum and, particularly advantageously, 95% as minimum, thus a particularly simple construction can be achieved.

    It is possible to achieve a particularly uniform heat distribution and / or thermal distribution if the induction cooking field comprises at least one other inductor that is at least essentially identical to the inductor, where the inductors comprise approximately or exactly the same effective distance with respect to the cooking field plate. The expression "effective distance with respect to the cooking field plate" refers to the distance that corresponds to the arithmetic mean of the distances obtained by adding the distances of all the coils of an inductor with respect to the field plate of cooking and dividing the result by the number of coils. The expression "approximate or exactly the same effective distance" refers to the fact that the effective distance of an inductor differs with respect to the effective distance of another inductor by a maximum of 10%.
    It is also proposed that the inductors intercalate with each other, at least when observed in the direction perpendicular to the main extension plane of the cooking field plate. The expression that "an object is intercalated with another object at least when observed in the direction perpendicular to the main extension plane of the cooking field plate" refers to the existence of at least one line that is perpendicular to the extension plane main of the cooking field plate and running through the object and the other object, at least when observed in the direction perpendicular to the main extension plane of the cooking field plate. As a result, a field of induction cooking particularly compact and / or flexible.
    The invention also refers to a method for operating an induction cooking field, where the induction cooking field comprises at least one cooking field plate, at least a first coil, and at least a second coil, which are displaced relative to each other at least in the direction perpendicular to the cooking field plate, in particular, at least when observed in the direction parallel to the main extension plane of the cooking field plate, where the first coil and the second coil will be activated at least temporarily simultaneously. In this way, it is possible to advantageously increase the efficiency, in particular, the efficiency of the power, the efficiency relative to the installation space, the efficiency of the components and / or the efficiency of the costs, and / or the flexibility. In addition, the distribution and / or disposition of the coils can be improved, which leads to a particularly uniform distribution of power, thanks to which an advantageous thermal distribution can be achieved at the base of a cooking drum.

    Other advantages of the invention are drawn from the following description of the figures. Four examples of realization of the invention are represented in the figures. The figures, description and claims contain numerous features in combination. The person skilled in the art will consider the characteristics advantageously also separately, and will gather them in other reasonable combinations.

    Figure 1 shows a top view of an example of an induction cooking field 24a. In the present case, the induction cooking field 24a is carried out as a matrix cooking field and / or as a flexible cooking field. The induction cooking field 24a comprises an induction cooking field. The induction cooking field comprises a cooking field plate 10a. The cooking field plate 10a is adjustable and comprises flexible and / or variable heating zones. The cooking field plate 10a and / or the heating zones are provided to heat at least one cooking drum 26a.

    The induction cooking field also comprises a user interface 28a. The user interface 28a is provided to control the operation of the induction cooking field 24a and / or the induction cooking field, by introducing and / or selecting one or more parameters such as heating power, heating density , the degree of heating and / or the heating zone.
    In addition, the induction cooking field comprises a control unit 18a. The control unit 18a comprises a processing unit, a memory unit, and an operating program that is stored in the memory unit and that is executed by the processing unit. The control unit 18a is provided to control the cooking processes.
    The induction cooking field also comprises at least one inductor 20a, 22a, in this case, multiple inductors 20a, 22a, specifically, between 12 and 48 inductors 20a, 22a, where, for simplicity, in Figures 1 and 2 only two of the inductors 20a, 22a are accompanied by reference symbols. The inductors 20a, 22a are arranged under the cooking field plate 10a, correspond to heating units, and are at least essentially identical. In addition, the inductors 20a, 22a are arranged such that they comprise the same effective distance with respect to the cooking field plate 10a. The inductors 20a, 22a are provided to create flexible heating zones, as well as to generate an alternating electromagnetic field that is transformed into heat at the base of the cooking battery 26a by eddy currents and / or magnetization and demagnetization effects. Alternatively, it is conceived that an induction cooking field comprises two, four and / or six non-flexible heating zones and / or two, four and / or six inductors, where each inductor is assigned to one of the heating zones.
    Next, only one inductor 20a of the inductors 20a, 22a is described in more detail with respect to Figures 3 and 4. In this way, the following description can also be applied to the other inductors 22a of the inductors 20a, 22a, and that inductors 20a, 22a are constructed in at least essentially identical manner.
    The inductor 20a comprises a first coil 12a. The first coil 12a is formed as a spiral coil, it is approximately or exactly circular at least when observed in the direction perpendicular to the main extension plane of the cooking field plate 10a, it comprises fifteen turns in a layer, and is arranged

    way directly adjacent to the cooking field plate 10a. As an alternative, it is conceived that a first coil comprises any other number of turns and / or layers. In this way, a first coil could be formed as a solenoid and / or elliptical coil. In addition, the inductor 20a comprises a second coil 14a. The second coil 14a is formed as a spiral coil, it is approximately or exactly circular at least when observed in the direction perpendicular to the main extension plane of the cooking field plate 10a, it comprises fifteen turns in a layer, and is at least essentially identifies the first coil 12a. In addition, the second coil 14a is displaced relative to the first coil 12a at least in the direction perpendicular to the cooking field plate 10a, and is arranged below the first coil 12a with respect to the cooking field plate 10a . Thus, the second coil 14a is arranged directly adjacent to the first coil 12a at least when viewed in the directions perpendicular and parallel to the main extension plane of the cooking field plate 10a.
    Also, the second coil 14a is displaced considerably with respect to the first coil 12a at least in the direction parallel to the cooking field plate 10a. The second coil 14a is thus arranged with respect to the first coil 12a, such that the geometric center of the second coil 14a is distanced from the outer limit of the first coil 12a at least when observed in the direction perpendicular to the plane of main extension of the cooking field plate 10a. In addition, the first coil 12a and the second coil 14a overlap at least partially at least when viewed in the direction perpendicular to the main extension plane of the cooking field plate 10a. In the present case, the overlapping area between the first coil 12a and the second coil 14a amounts to approximately 30% of the total surface area of the first coil 12a or the second coil 14a at least when observed in the direction perpendicular to the extension plane main of the cooking field plate 10a.
    In the present case, the first coil 12a and the second coil 14a are additionally electrically connected. In this way, the first coil 12a and the second coil 14a are connected in series. As an alternative, it is conceived that a first coil and a second coil are connected in parallel, or that they are not connected. Thus, it is also conceived that a second coil is part of another inductor. Likewise, it is conceived that a second coil comprises any other number of turns and / or layers. In addition, a second coil could be formed as a solenoid and / or elliptical coil. Additionally, it is conceived that a second

    coil is rotated and / or specularly reproduced relative to a first coil with respect to a plane that is parallel to the main extension plane of a cooking field plate.
    Also, the inductor 20a comprises a third coil 16a. The third coil 16a is formed as a spiral coil, is approximately or exactly circular at least when viewed in the direction perpendicular to the main extension plane of the cooking field plate 10a, comprises fifteen turns in a layer, and is at least essentially identifies the first coil 12a and the second coil 14a. At least in the direction perpendicular to the cooking field plate 10a, the third coil 16a is also displaced with respect to the first coil 12a as well as with respect to the second coil 14a. The third coil 16a is arranged below the first coil 12a and below the second coil 14a with respect to the cooking field plate 10a. Thus, the third coil 16a is arranged directly adjacent to the second coil 14a at least when viewed in the directions perpendicular and parallel to the main extension plane of the cooking field plate 10a.
    In addition, the third coil 16a is displaced considerably relative to the first coil 12a at least in the direction parallel to the cooking field plate 10a. Thus, the third coil 16a is arranged with respect to the first coil 12a such that the geometric center of the third coil 16a is distanced from the outer limit of the first coil 12a at least when observed in the direction perpendicular to the main extension plane of the cooking field plate 10a. Also, the third coil 16a is displaced considerably relative to the second coil 14a at least in the direction parallel to the cooking field plate 10a. Thus, the third coil 16a is disposed with respect to the second coil 14a such that the geometric center of the third coil 16a is distanced from the outer limit of the second coil 14a at least when observed in the direction perpendicular to the main extension plane of the cooking field plate 10a.
    Also, the first coil 12a and the third coil 16a overlap partially or completely at least when viewed in the direction perpendicular to the main extension plane of the cooking field plate 10a. In this case, the overlapping area between the first coil 12a and the third coil 16a amounts to approximately 30% of the total surface area of the first coil 12a or the third coil 16a at least when observed in the direction perpendicular to the plane of

    main extension of the cooking field plate 10a. Likewise, the second coil 14a and the third coil 16a overlap partially or completely at least when viewed in the direction perpendicular to the main extension plane of the cooking field plate 10a. In this case, the overlapping area between the second coil 14a and the third coil 16a amounts to approximately 30% of the total surface area of the second coil 14a or the third coil 16a at least when observed in the direction perpendicular to the main extension plane of the cooking field plate 10a.
    In addition, the first coil 12a, the second coil 14a, and the third coil 16a are electrically connected. In this way, the first coil 12a, the second coil 14a, and the third coil 16a are connected in series, and form the inductor 20a.
    Alternatively, it is conceived that a first coil and a third coil and / or a second coil and a third coil are connected in parallel, or are not connected. It is also conceived that a third coil is part of another inductor. Likewise, it is conceived that a third coil comprises any other number of turns and / or layers. Also, a third coil could be made as a solenoid and / or elliptical coil. Additionally, it is conceived that a third coil is rotated and / or specularly reproduced relative to a first coil or a second coil with respect to a plane that is parallel to the main extension plane of a cooking field plate. In addition, it is also conceived that a third coil is not used, so that an inductor is formed solely by a first coil and a second coil.
    The control unit 18a is provided to control the cooking processes by regulating the heating power of the inductor 20a and / or the inductors 20a, 22a by activating a power supply (not shown). Consequently, the control unit 18a is provided to drive the first coil 12a, the second coil 14a, and the third coil 16a simultaneously. As a result, a uniform thermal distribution can be achieved in the cooking drum 26a, where the effective diameter of the inductor 20a can be increased, while maintaining constant distance between the centers of the coils 12a, 14a,
    16th As an alternative, it is conceived to supply different power supplies to the coils of a power supply unit. Likewise, at least in order to improve the efficiency of the induction cooking field 24a, the control unit 18a is provided to only drive the inductors 20a, 22a that are arranged at least partially below the cooking drum 26a.

    Figure 5 shows the inductor 20a and another inductor 22a of the inductors 20a, 22a at least essentially identical. The other inductor 22a is arranged directly adjacent to the inductor 20a at least when viewed in the directions perpendicular and parallel to the main extension plane of the cooking field plate 10a. The inductor 20a and the other inductor 22a are arranged such that the inductor 20a and the other inductor 22a comprise the same effective distance with respect to the cooking field plate 10a, which results in a heat distribution and / or particularly uniform thermal distribution in the cooking battery 26a. In the present case, the effective distance with respect to the cooking field plate 10a is between 3 mm and 15 mm.
    Also, the inductor 20a and the other inductor 22a are arranged in such a way that the inductor 20a and the other inductor 22a are interspersed with each other. Thus, another second coil 15a of the other inductor 22a, which is disposed between another first coil 13a of the other inductor 22a and another third coil 17a of the other inductor 22a and which is equal to the second coil 14a, is arranged at least partially between the first coil 12a and the third coil 16a at least when viewed in the direction perpendicular and / or parallel to the main extension plane of the cooking field plate 10a. Therefore, there is at least one line that is perpendicular to the main extension plane of the cooking field plate 10a and that runs through the inductor 20a and the other inductor 22a, at least when observed in the direction perpendicular to the plate of cooking range 10a. By overlapping the inductors 20a, 22a, the resolution of the coverage and, in this way, the flexibility of the induction cooking field 24a can be advantageously improved, which leads to a particularly uniform distribution of power. In the present case, the inductors 20a, 22a are also fed by the same power source. As an alternative, it is also conceived that power is provided to different inductors, in particular, directly adjacent inductors, using different power supplies and / or different phases of a power supply, thereby advantageously reducing magnetic interference and / or magnetic disturbances effectively.
    Figures 6a10 show other examples of realization of the invention. The following descriptions are essentially limited to the differences between the embodiments, where, in relation to components indicated in the same way, in particular, in terms of components with the same reference symbols, reference may be made to the figures and / or the description of the embodiment example of figures 1 to 5. For the differentiation of the embodiment examples, the letter "a" appears
    5

    30
    behind the reference symbols of the embodiment example of Figures 1 to 5, and has been replaced by the letters "b" to "d" in the reference symbols of the embodiment examples of Figures 6 to 10.
    Figures 6 to 8 show another embodiment of the invention. The letter "b" is postponed to the reference symbols of the other embodiment of Figures 6 to 8. The other embodiment of Figures 6 to 8 differs from the previous embodiment at least basically in the construction of inductors 20b,
    22b of a cooking field by induction.
    In the present case, each inductor 20b, 22b comprises exactly two coils 12b, 13b, 14b, 15b. The first coil 12b, the second coil 14b, another first coil 13b, and another second coil 15b are approximately or exactly semicircular, at least when viewed in the direction perpendicular to the main extension plane of the cooking field plate 10b. In this way, the first coil 12b and the second coil 14b are spaced apart from each other at least in the direction perpendicular to the main extension plane of the cooking field plate 10b.
    Therefore, the first coil 12b and the second coil 14b do not overlap. Likewise, the other first coil 13b and the other second coil 15b are spaced apart from each other at least when viewed in the direction perpendicular to the main extension plane of the cooking field plate 10b. Therefore, the other first coil 13b and the other second coil 15b do not overlap.
    In this way, the inductor 20b and the other inductor 22b are specularly symmetrical with respect to a plane that is perpendicular to the main extension plane of the cooking field plate 10b.
    As can be seen in Figure 8, the inductor 20b and the other inductor 22b comprise an approximate or exactly interwoven shape.
    Figure 9 shows another embodiment of the invention. The letter "c" is postponed to the reference symbols of the other embodiment of Figure 9.
    The other embodiment of Figure 9 differs from the previous embodiments at least basically in the construction of inductors 20c, 22c of an induction cooking field.
    In the present case, each inductor 20c, 22c comprises exactly two coils 12c,
    13c, 14c, 15c. The first coil 12c and the other second coil 15c are at least essentially identical. Thus, the first coil 12c and the other second coil 15c are approximately or exactly circular at least when observed in the

    direction perpendicular to the main extension plane of the cooking field plate 10c. Also, the second coil 14c and the other first coil 13c are at least essentially identical. The second coil 14c and the other first coil 13c are approximately or exactly semicircular at least when observed in the direction perpendicular to the main extension plane of the cooking field plate 10c.
    Also, the second coil 14c is arranged such that the first coil 12c completely covers the second coil 14c at least when viewed in the direction perpendicular to the main extension plane of the cooking field plate 10c. In addition, the other second coil 15c is arranged such that the other first coil 13c covers at least partially the other second coil 15c at least when viewed in the direction perpendicular to the main extension plane of the cooking field plate 10c.
    In this way, the inductor 20c and the other inductor 22c are rotationally symmetrical with respect to a plane that is parallel to the main extension plane of the cooking field plate 10c.
    Thus, the first coil 12c and the other second coil 15c overlap at least partially at least when viewed in the direction perpendicular to the main extension plane of the cooking field plate 10c. In the present case, the overlapping area between the first coil 12c and the other second coil 15c amounts to approximately 30% of the total surface area of the first coil 12c or the other second coil 15c at least when observed in the direction perpendicular to the main extension plane of the cooking field plate 10c.
    Figure 10 shows another embodiment of the invention. The letter "d" is postponed to the reference symbols of the other embodiment of Figure 10.
    The other embodiment of Figure 10 differs from the previous embodiments at least basically in the construction of inductors 20d, 22d of an induction cooking field.
    In this case, the inductors 20d, 22d are made as elongated coils, also known as vector coils. Thus, at least the first coil 12d, the second coil 14d, the other first coil 13d, and the other second coil 15d are partially or totally oval and / or elliptical at least when observed in the direction perpendicular to the main extension plane of the 10d cooking field plate.
