In the installation position, the unit underlying is intended to be placed on top of a cooking field, specifically on top of the cover plate.The cover plate is made as a kitchen worktop. The cooking system presents the cooking field. The term "cooking field ”Includes the concept of a unit that has at least one induction heating unit, a power unit, and a cooking unit electronics unit, which is provided to activate the power supply unit in the heating operating state to supply power, in particular electric power, to the induction heating unit, where, in the heating operation state, the induction heating unit is provided for supplying energy, in particular, electromagnetic energy, in particular inductive energy, to at least one cooking battery element, in particular, to the cooking battery element, depending on the supply made by the power supply unit. The cooking field can have a cooking field plate, where the cover plate can be made at least partially in one piece with the cooking field plate and / or completely as a cooking field plate. The underlying unit differs from the cooking field, in particular, from the cover plate and / or is advantageously mobile relative to the cooking field, in particular, to the cover plate. The underlying unit is made as a separate unit. An underlying unit made as a separate unit can be positioned in any position on the cover plate. The underlying unit is intended to be used with the cooking field and, preferably, with different cooking fields. The cooking field is intended to be used with at least one underlying unit and, advantageously, with at least two, advantageously, with at least three and, preferably, with at least four underlying units, at least essentially

    simultaneous. Preferably, the cooking field is made as a matrix cooking field.
    The induction heating unit is intended to transform an electrical energy into an inductive energy by means of at least one induction heating element that is made as a coil, preferably by means of multiple induction heating elements, and to be supplied to an induction element. cooking battery to transform it into heat. The underlying unit largely or completely forms the basis for the heated cooking battery element. The underlying unit has an approximate or exactly plate-shaped conformation.
    The term "positioning unit" includes the concept of a unit that in at least one operating state recognizes the position of the underlying unit with respect to the induction heating unit and supplies it, in particular, indicates, for further processing The expression that "the positioning element is intended to contribute at least in part to the positioning of the underlying unit" includes the concept that the positioning element conforms a part of a positioning unit and contributes at least to help to position the underlying unit relative to the cooking field.
    The term "intended" includes the concepts of conceived and / or provided in a specific manner. The expression that an object is intended for a particular function includes the concept that the object satisfies and / or performs this purpose. function determined in one or more application and / or operating states.
    In addition, it is proposed that the positioning element be partially or completely integrated into the underlying unit. In this way, a compact positioning element can be obtained and advantageously saving construction space, as well as reducing material and production costs. The expression that "the positioning element is partially or completely integrated in the underlying unit" includes the concept that the underlying unit envelops and / or drags around the positioning element at least by areas and / or by sections Specifically, the positioning element is completely integrated in the underlying unit.

    which can reduce energy costs. In addition, the communication of the positioning element with the induction heating unit is advantageously enhanced by an inductive signal.
    In order to obtain a better positioning of the underlying unit, in a preferred embodiment of the invention, it is advantageously proposed that the positioning unit has at least one other positioning element associated with the induction heating unit and that it corresponds with the positioning element, which is intended to interact with the positioning element to help position the underlying unit relative to the induction heating unit. In this way, the positioning of the underlying unit can be improved relative to the induction heating unit, as well as the recognition of the positioning, and the compatibility of the positioning unit can be increased. The other positioning element is integrated in the induction heating unit at least partially, advantageously, completely.
    Furthermore, it is proposed that the induction heating unit has at least one induction heating element, in particular, a heating coil, with which the other positioning element is partially or completely made in one piece. The expression "partially or completely in one piece" includes the concept that at least one component of at least one object, in particular, the induction heating element, is made in a piece with at least one component of at least another object, specifically, with the other positioning element. The other positioning element is partially or completely realized as an induction heating element. In this way, another positioning element can be advantageously achieved with which construction space is saved, as well as reducing material and / or production costs.
    In order to achieve a better positioning by means of the positioning unit, it is proposed that the positioning element be provided to inductively engage with the other positioning element to aid positioning. Thus, the transmission of inductive signals, in particular, of a magnetic field, as well as the operation to aid positioning can be advantageously improved. The term "inductively coupled" includes the concept that an inductive signal of a first object, namely, a magnetic field of the other positioning element, induces an electrical current in the positioning element, namely an induction current, and / or an electric voltage, namely, an induction voltage.

    Another positioning element is provided to generate an inductive signal, in particular, a magnetic field, which induces a voltage and / or a current in the positioning element, where there is a correlation between the induced voltage and / or the induced current and the inductive parameter, in particular, the inductive conductance already mentioned above, of the positioning element. However, as an alternative, also an inductive signal, specifically a magnetic field, in the positioning element could induce a current and / or a voltage in the other positioning element.
    In addition, it is proposed that the cooking system has a position indicating unit, which is intended to indicate positioning by means of the magnitude of an inductive parameter, in particular, the inductive parameter already introduced above, of the positioning element. The position indicating unit has at least one position indicating element, which indicates by means of an analog display and, in particular, by means of a display indicating element and / or an LED indicating element, the position, for example, indicating the power by means of the magnitude of the inductive parameter in a row of LEDs and / or in a direction indicator, corresponding to the magnitude of the inductive parameter, or in an indicator of the position in which the heating power is shown coded chromatically in a two-dimensional representation in the area of the positioning unit, specifically, of the underlying unit. There is a correlation between the inductive parameter and the inductive conductance already mentioned above, specifically, the induction voltage. The cooking system additionally has a measuring unit with at least one measuring element, which is intended to measure the inductive parameter, in particular, the induction voltage, of the positioning element. At least one measuring element is associated with each positioning element, each of which is made as a measuring circuit. The position indicating unit is intended to indicate the positioning of the positioning element relative to the induction heating unit, in particular, relative to the other positioning element of the positioning unit, by inductive conductance, is made as an analog display, as a display indicator and / or, preferably, as an LED indicator, and is arranged next to the underlying unit, in particular, it is integrated into it at least partially. In this way, the user can carry out the positioning and, with this, the comfort of use can be increased.
    In order to achieve flexibility for the underlying unit and, in particular, a better and more accurate positioning, it is further proposed that the positioning unit
    understand multiple positioning elements that are associated with the unit

    underlying and that they are at least essentially and, preferably, totally, of the same construction as the positioning element. The positioning unit comprises multiple positioning elements that are associated with an underlying unit, and multiple other positioning elements that are associated with the induction heating unit. The at least one positioning element and another positioning element are inductively coupled. In particular, multiple positioning elements and multiple other positioning elements are inductively coupled. The expression "at least essentially of the same construction" includes the concept that one of the positioning elements differs from the positioning elements in terms of their external form and / or the smaller volume that the external form comprises in 30% at most, advantageously, at 20% maximum, preferably, at 10% maximum and, particularly advantageously, at 5% maximum, as well as in terms of mass at 30% as maximum, advantageously, at a maximum of 20%, preferably at a maximum of 10% and, particularly advantageously, a maximum of 5%.
    In order to achieve a better positioning and greater comfort of use, it is also proposed that the cooking system present the cooking battery element, where the positioning unit is provided to help position the cooking battery element relative to the underlying unit and induction heating unit. The positioning of the cooking battery element is relative to the underlying unit by the additional determination of another inductive parameter, which causes the modification of the voltage and / or current through the relative positioning of the underlying unit with respect to the element of cooking battery. The other inductive parameter is correlated with the inductive conductance and has a different value with respect to the inductive parameter.
    In addition, a procedure is proposed to position a cooking battery element of a cooking system with a positioning unit, which is intended to help position the underlying unit relative to the induction heating unit and which presents the at least one positioning element associated with the underlying unit, which is configured as an inductive element, where, by means of the positioning element, the positioning of the underlying unit relative to the induction heating unit is contributed at least in part. Thus, it is possible to provide through the positioning element a positioning that is operative regardless of a power source, so that the
    energy costs and, consequently, one can advantageously dispense with a

    Cable connection with an external power source. Also, the flexibility of application can be increased, as well as the convenience of use. It is also possible to advantageously reduce material and / or production costs, as well as maintenance costs.

Additionally, the cooking field 34 has another unit of induction heating 32. The induction heating unit 18 and the other induction heating unit 32 are made with the same construction. The description of the induction heating unit 18 can be applied to the other induction heating unit 32.
    A surface area of the cover plate 16, below which the cooking field 34 is arranged, defines a cooking area. Additionally, a cooking field may comprise other induction heating units. The cover plate 16 is provided so that the underlying unit 12 rests on it. In the heating operating state, the underlying unit 12 is disposed between the cover plate 16 and the cooking battery element 14.
    The cooking field 34 further comprises a control unit 36. The control unit 36 is arranged under the cover plate 16. In this case, the control unit 36 is arranged under the induction heating unit 18. In At least one heating operating state of the cooking field 34, the control unit 36 regulates the power supply to the induction heating units 18, 32. Alternatively, the control unit may also be arranged horizontally displaced with with respect to an induction heating unit.
    In the heating operating state, the underlying unit 12 prevents heat transmission from the cooking battery element 14 to the cover plate 16. The underlying unit 12 has a discoid conformation. In the present embodiment, the underlying unit 12 has a diameter of approximately 180 mm. The underlying unit 12 has a thickness of approximately 2 mm.
    The underlying unit 12 is largely composed of an essentially flexible material. The material of which the underlying unit 12 is composed largely has a low thermal conductivity, is insulating and / or easy to clean. In this exemplary embodiment, the underlying unit 12 is largely composed of silicone. Alternatively, the underlying unit may be composed of an elastic plastic and have a thickness of more than 2 mm or less than 2 mm.
    The underlying unit 12 has an electronic unit 40, as shown in the detailed view of the underlying unit 12 of Figure 2. In an operating state, the

    35
    electronics unit 40 performs at least one function. Before the start of the heating operating state, the electronics unit 40 performs several functions in the operating state. The electronics unit 40 is provided for a sensor function, for example, of the cooking battery parameters such as temperature, cooking duration, the cooking battery weight and / or for an indicator function and / or of control by means of a control unit 42 and an indicator unit 44.
    In the present case, the cooking system 10 also has a positioning unit 20. The positioning unit 20 is at least partially arranged in the underlying unit 12 and / or formed by it. In addition, the positioning unit 20 is partially arranged in the induction heating unit 18 and / or formed by it. The positioning unit 20 is provided to help position the underlying unit 12 relative to the induction heating unit 18. In addition, the positioning unit 20 is provided to help position the cooking battery element 14 in a relative manner. to the underlying unit 12 and the induction heating unit 18. To this end, the positioning unit 20 has a positioning element 22. The positioning element 22 is associated with the underlying unit 12 and is integrated in the underlying unit 12, being arranged in her. The positioning element 22 is provided to contribute at least in part to the positioning of the underlying unit 12 relative to the induction heating unit 18. The positioning element 22 is made as an inductive element 24, in particular, as a coil.
    In addition, the positioning unit 20 comprises multiple additional positioning elements. The additional positioning elements are associated with the underlying unit 12 and are integrated in the underlying unit 12, being arranged therein. The additional positioning elements are made as inductive elements, in particular, as coils. The additional positioning elements are made with the same construction as the positioning element 22. In this case, the underlying unit 12 comprises five positioning elements. The positioning elements in this case are concentrically and uniformly distributed by the underlying unit 12. Alternatively, the positioning elements can also be made differently, for example, in terms of the number of turns of the coil, the size of the diameter of the coil, or in the shape of the outline of the coil. By way of example, the positioning elements may be concentrically arranged and / or concentrically made with respect to the underlying unit.

    Also, the positioning unit 20 has another positioning element 26. The other positioning element 26 is associated with the induction heating unit 18, and is made in the induction heating unit 18 and / or formed by it. The other positioning element 26 is realized as another inductive element. The other positioning element 26 is made in one piece with the induction heating element 28, in particular, as a coil. The other positioning element 26 is realized as another positioning element that corresponds to the positioning element 22, and correspondingly to the additional positioning elements. The other positioning element 26 is provided to interact with the positioning element 22 to position the underlying unit 12 relative to the induction heating unit 18. Also, the other positioning element 26 is provided to provide a magnetic field 46 In particular, the other positioning element 26 is provided to generate a magnetic field 46 by an applied electric current 56. The other positioning element 26 configures a magnetic field 46 by means of the electric current 56 flowing through the other positioning element 26. The magnetic field 46 is more intense at the geometric center of the other positioning element 26 than at the edges of the other positioning element 26. In addition, the other positioning element 26 is provided to interact with the additional positioning elements to help position the underlying unit 12 relative to the induction heating unit 18.
    The positioning element 22 and the other positioning element 26 are inductively coupled to aid positioning. As the schematic representation of a coupling of Figure 3 shows, the positioning element 22 is coupled to a magnetic field 46 of the other positioning element 26. The magnetic field 46 of the other positioning element 26 passes through the positioning element 22 The magnetic field induces in the positioning element 22 an electric current, in particular an induction current 52. Additionally, the magnetic field 46 generates in the positioning element 22 an electric voltage, in particular an induction voltage. There is a correlation between the intensity of the induction current 52 in the positioning element 22 and the intensity of the magnetic field 46. The intensity of the induction current 52 in the
    positioning element 22 is proportional to the intensity of the magnetic field 46.

    There is a correlation between the intensity of the induction voltage 54 in the positioning element 22 and the intensity of the magnetic field 46. The induction current 52 and the induction voltage 54 are used as electrical energy to supply power to the electronics unit 40. In addition, the induction current 52 configures another magnetic field of the positioning element 22. Also, the induction current 52 and the induction voltage 54 configure the inductive conductance of the positioning element 22. In addition, the other positioning element 26 and the other additional positioning elements induce in each case an additional induction voltage on the additional positioning elements of the underlying unit 12. The magnitudes of the additional induction voltages are dependent on the positioning of the additional positioning elements relative to the other positioning elements and They can differentiate each other.
    The underlying unit 12 further comprises a measuring unit 48 (see Figure 2). The measuring unit 48 is provided to measure the induction voltage 54 of the positioning element 22. For this, the measuring unit 48 has a measuring element 50. The measuring element 50 is associated with the positioning element 22, it is provided To measure the induction voltage 54 of the positioning element 22, it is made as a measuring circuit, is adapted to the positioning element 22, and is connected to it. In addition, the measuring unit 48 has multiple additional measuring elements. Each of the additional measuring elements is associated with one of the additional positioning elements. The additional measuring elements are provided in each case to measure the induction voltage of one of the positioning elements. The additional measuring elements are made in each case as a measuring circuit. Each of the additional measuring elements is adapted to one of the additional positioning elements. Each of the additional measuring elements is connected to one of the additional positioning elements. Alternatively or additionally, it is conceived that the measurement unit is intended to measure an induction current and / or the induced magnetic fields of the positioning elements of an underlying unit.
    In addition, the cooking system 10 has a position indicating unit 30. The position indicating unit 30 is provided to indicate the positioning by means of the magnitude of an inductive parameter of the positioning element 22, in particular, by means of the magnitude of the induction voltage 54 of the positioning element 22. The indicating unit of position 30 is provided to indicate the positioning by
    mean of the magnitude of the additional induction voltage of the elements of
    12
    additional positioning. In this case, the position indicating unit 30 is preferably made as an LED indicator. The position indicating unit 30 indicates the positioning of the positioning element 22 by the induction voltage 54 and the additional positioning element by the additional induction voltages. The indicating unit of position 30 indicates the positioning of the underlying unit 12 by induction voltage 54 and additional induction voltages. In this case, the position indicating unit 30 is integrated in the underlying unit 12, specifically, it is integrated in the indicating unit 44. Alternatively, the position indicating unit could also be integrated in the cover plate and 10 communicate through a signal transmitter integrated in the underlying unit. In the present case, the position indicating unit 30 is made as an LED indicator, and indicates the position of the underlying unit 12, for example, by means of a row of LEDs and / or a digital display of the power in numerical format, showing a value of the heating power corresponding to the induction voltage 54 and the additional induction voltage 15 as a value by means of the LED row and / or a percentage indication. Alternatively or additionally, the position indicating unit could show an indication of the direction in the form of arrows oriented relative to each other, which indicate the direction of the position with a higher value of the heating power. Alternatively, the position indicating unit could be realized as a display, which shows heating power values through a section and / or the entire support area of an underlying unit in a chromatically coded manner and / or indicates the direction towards the position with a higher value of the heating power.
