    The invention solves the technical problem of providing a generic cooking field device 15 with better properties in relation to its contacting. According to the invention, this technical problem is solved by means of an induction cooking field device, with a support unit that is intended to support on it at least one cooking battery element to be heated and which has at least a support elevation, delimited locally, which is intended to be in contact with the cooking battery element.

The support unit is a flat unit provided in at least one operating state to accommodate at least one cooking battery element 25 in order to heat it. The support unit comprises at least one flat base element, and at least one support elevation, which is carried out high with respect to the base element. Advantageously, the support elevation has a height relative to the base element of at least 0.2 mm to a maximum of 5 mm. In addition, the support elevation has a maximum extension in a plane parallel to the main extension plane 30 of the support unit, which amounts to a maximum of 20% to a maximum of 5% of the maximum extension of the base element in the parallel plane to the main extension plane of the support unit. Advantageously, the support elevation has a length of the main extension in the plane parallel to the main extension plane of the support unit of a maximum of 30 mm to a maximum of 20 mm. In addition, the support elevation can be partially flexible. Also, the support elevation is composed at least partially, preferably completely, of a material with a thermal conductivity of at least 1 W / (m ∙ K), at least 4 W / (m ∙ K). The support elevation can be composed here at least partially or completely, preferably completely by a metal, a metal alloy, a ceramic, a thermally conductive plastic and / or a thermally conductive silicone. Likewise, the support elevation is made in a semi-cylindrical shape, in the shape of a pyramidal trunk, in the shape of a truncated cone, in the shape of a parallelepiped and / or, in a way with a hemispherical shape. In addition, the support unit may also have several support elevations, preferably at least essentially of the same construction, which may be advantageously associated with a cooking battery element 45.

    The flexible object is an object that has at least a partial area and / or at least a part that, in a normal operating state, is advantageously elastically modifiable at least in its position at least 0.1 mm, to 0.5 mm, and which preferably generates an antagonistic force dependent on the modification of the position and, particularly preferably, proportional to the modification, which counteracts said modification. Preferably, the flexible object is repeatedly deformable without deterioration and again tends autonomously to its basic shape after deformation. The
    Object shapes are at least essentially of the same construction presenting external shapes made at least essentially identical to each other, but which can be differentiated from each other in at least one characteristic, for example, their internal structure, their material composition and / or its mode of operation However, regardless of production tolerances and / or within the framework of technical possibilities of production and / or 5 within the framework of standardized tolerances, objects at least essentially of the same construction are preferably identical to each other.

    According to one aspect of the invention, it is proposed that the support unit be made as a mobile and / or portable unit and that, in at least one heating operating state, 10 be provided to be arranged between the cooking battery element and A cover plate.

    The support unit is intended to be supported and / or placed on the cover plate. In this case, the support unit forms a base 15 for the cooking battery element to be heated and / or heated in the heating operating state. The support unit advantageously has an extension and / or extensions, in particular, a diameter, which is adapted to an extension and / or extensions, in particular, to the diameter, of the cooking battery element. The cover plate is an element that is intended to cover at least partially or preferably, completely, at least one heating unit that is provided in the heating operating state to inductively heat the cooking battery element. The cover plate can be made as a cooking field plate, for example, as a ceramic hob, and / or as a countertop, for example, as a kitchen countertop. By this embodiment, a cooking field device with better properties in relation to the contacting can be provided. Here, it is possible to obtain an advantageously exact and / or precise measurement of the operating parameters, in particular, of the temperature of the cooking battery element. In addition, an adaptable support unit can be provided in an advantageously flexible manner, which can be adapted to different conditions and / or requirements. In addition, efficiency is increased, in particular, power efficiency, heating efficiency, energy efficiency, component efficiency and / or cost efficiency.

    Preferably, the support unit is made in a stable manner, so it is possible to achieve an advantageous handling thereof. Thus, the support unit is an object whose external form does not vary at least within the framework of the defined tolerances and applying a maximum force below a limit value, with which the object is permanently deformed and / or Destroy Preferably, at least the base element of the support unit is composed at least partially or preferably, completely, of a mechanically stable and / or rigid material, namely, a ceramic, a metal, a ceramic hob and / or, preferably, a plastic material such as, for example, polyether ether ketone 40 (PEEK) and / or, advantageously, polyphenylene sulfide (PPS).

    The base element and the support elevation could be composed here, for example, of the same material, for example, of a plastic material and / or a ceramic. However, it is advantageously proposed that the support unit has at least one base element, in particular, the base element already mentioned above, which is partially or completely composed of a material that differs from the lifting material of support for. In this way, the support unit can be adapted particularly easily to different requirements and / or conditions.
     fifty
    Likewise, it is proposed that the support unit has at least one other support bounded locally defined, which is advantageously at least essentially of the same construction as the support lift and, in a particularly advantageous way, is associated with the same element of Cooking battery that support lifting. By way of
    preferably, the support unit has at least two others and, particularly preferably, at least three other, locally defined support elevations, which are advantageously at least essentially of the same construction as the support elevation and which, of particularly advantageously, they are associated with the same cooking battery element as the support lift. Thus, advantageous stability and / or safe and stable contact with the cooking battery element can be guaranteed.

    Furthermore, it is proposed that the cooking field device comprises at least one temperature sensor, for example, an NTC resistor and / or a PTC resistor, which is associated with the support elevation and which, at least when perpendicularly observed the main extension plane 10 of the support unit, be partially or completely arranged, preferably, largely or completely and, particularly preferably, completely, in the area of the support elevation. The area of the support elevation is the volume of the imaginary parallelepiped minor that wraps it tightly completely. The cooking field device may also comprise several temperature sensors, where at least one, advantageously exactly one, of each temperature sensor is associated with each support elevation of each support unit. In this way, an advantageously accurate and / or accurate temperature measurement can be achieved.

    The temperature sensor could be arranged next to the surface of the support unit, preferably, on the side of the base element opposite the support elevation. However, the support unit preferably comprises at least one hollow space in which the temperature sensor is arranged, so that an arrangement of the temperature sensor can be achieved with which space is advantageously saved and / or the space can be increased. safety of operation thanks to the advantageous protection of the temperature sensor. Preferably, the temperature sensor is embedded in the support unit here. The hollow space envelops the temperature sensor preferably completely.

    Likewise, it is proposed that the hollow space be filled with a thermoconducting material, which differs from the support elevation material and / or the base material. Preferably, the thermally conductive material here has a thermal conductivity of at least 4 W / (m K), advantageously, of at least 6 W / (m ∙ K), preferably, of at least 8 W / (m ∙ K) and, particularly preferably, of at least 10 W / (m ∙ K). Particularly advantageously, the thermally conductive material can be made as a thermally conductive paste. In this way, the thermal conductivity of the support unit can be improved. 35

    In a particularly preferred embodiment, it is proposed that the temperature sensor be integrated directly into the support elevation. Thus, thermal contact and, thus, temperature measurement can be improved to a greater extent.

    According to another aspect of the invention, an induction cooking field device is proposed, with a support unit, which is provided to support on it at least one cooking battery element to be heated and which has at least one support boundary delimited locally, which is intended to be in contact with the cooking battery element, and with at least one magnetic unit, associated with the elevation of support, which is partially or completely arranged, preferably, largely or completely and, particularly preferably, completely, in the area of the support elevation, at least if observed perpendicularly with respect to the main extension plane of the support unit, and intended to provide a field magnetic clamping by attraction for the cooking battery element made at least partially magnetic. The magnetic holding field is a magnetic field intended to exert an attractive force on the magnetic battery cooking element and, thus, improve the contact between the support elevation and the cooking battery element. Also, the support unit can be carried out in this case as
    cover plate, in particular, as a cooktop, for example, as a hob, and / or as a countertop, for example, as a kitchen countertop, where, also in this case, the cooking field device can have at least one temperature sensor, in particular, the aforementioned temperature sensor, which can be arranged at least partially in the area of the support elevation, advantageously, in a hollow space, preferably filled with a thermoconductive material, and which in a particularly advantageous manner can be integrated in the support elevation. In this way, the advantages already mentioned above can be achieved. By a corresponding embodiment of the cooking field device, the contacting can be improved. Here, it is possible to obtain an advantageously accurate and / or precise measurement of the 10 operating parameters, in particular, of the temperature of the cooking battery element. In addition, an adaptable support unit can be provided in an advantageously flexible manner, which can be adapted to different conditions and / or requirements. In addition, efficiency is increased, in particular, power efficiency, heating efficiency, energy efficiency, component efficiency and / or cost efficiency.

    It is possible to achieve a cooking field device of particularly simple structure if the magnetic unit comprises at least, advantageously exactly, a magnetic element made as a permanent magnet, advantageously, as a rare earth magnet. 20 Preferably, the magnetic element is composed partially or completely, preferably, largely or completely and, preferably, completely, by neodymium-iron-boron, a neodymium-iron-boron alloy, samarium-cobalt and / or by an alloy of samarium-cobalt.
     25
    Likewise, it is proposed that the magnetic unit be embedded in the support unit, in particular, in the base element, partially or completely, preferably, largely or completely and, preferably, completely. When the support elevation is observed perpendicularly, the magnetic unit is advantageously arranged below the temperature sensor. In this way, an advantageous attraction of the cooking battery element and, simultaneously, an advantageous temperature measurement can be achieved.

    Figure 1 shows an example of a cooking system 32a, in perspective view. The cooking system 32a comprises at least one cooking battery element 12a. In this case, the cooking battery element 12a is made by way of example as a cooking pot. The cooking battery element 12a is made as a cooking battery element suitable for induction and is composed of a magnetic material at least partially. In the present case, at least the base of the cooking battery element 12a 20 is composed of a magnetic material at least partially. Alternatively, the cooking system could also comprise various cooking battery elements and / or other cooking battery elements.

The cover plate 18a is provided to support the cooking battery element 12a and thus absorb the force of the weight of the cooking battery element 12a. However, the cover plate could also be made as an alternative like any other hob and / or cooking field plate. 30

    In addition, the cooking system 32a comprises a heating unit 34a. The heating unit 34a is arranged under the cover plate 18a and is made as an induction heating unit. In this case, the heating unit 34a comprises multiple heating elements arranged as a matrix (not shown). In at least one heating operating state, the heating unit 34a is provided to inductively heat the cooking battery element 12a. Alternatively, the heating unit could have at least one heating element that conforms to a fixed heating zone. In addition, the heating unit could have two, three, four, five and / or six separate heating elements 40, each of which is intended to heat a cooking battery element.

    The cooking system 32a further comprises a cooking field device. The cooking field device comprises at least one support unit 10a. The support unit 10a is flat, and is made separately from the cover plate 18a and the cooking battery element 12a. In addition, the support unit 10a is mobile, is made as a support mat, and is stably. However, the support unit could also be carried out as an alternative with flexible form. The support unit 10a is made as a mobile and / or portable unit. fifty
    The support unit 10a is intended to be supported and / or placed on the cover plate 18a, specifically, above the heating unit 34a. In addition, the support unit 10a is provided so that the cooking battery element 12a rests on it. In the heating operating state, the support unit 10a is intended to be
    disposed between the cooking battery element 12a and the cover plate 18a. In this case, the support unit 10a forms in the heating operating state a base for the cooking battery element 12a heated and / or to be heated, so that the cover plate 18a can be advantageously protected against to excessive heating. 5

    The support unit 10a comprises a base element 20 (see also Figure 2). The base element 20a forms the base body of the support unit 10a and is flat. If it is observed in a direction perpendicular to the main extension plane of the base element 20a, the base element 20a is circular. In addition, the base element 20a has a diameter that is adapted to the diameter of the cooking battery element 12a. The base element 20a is stably. In this case, the base element 20a is composed of a plastic, in particular, polyphenylene sulfide (PPS). However, as an alternative, the base element could also be oval or rectangular and / or composed of another material such as, for example, polyether ether ketone (PEEK), a silicone, or a ceramic. fifteen

    In addition, the support unit 10a comprises a control unit 36a. The control unit 36a is connected with the base element 20a, in this case, it is connected in one piece with the base element 20a. The control unit 36a is intended to adjust and / or indicate different control parameters, for example, temperature, cooking time and / or heating power. However, the control unit could also be made as an alternative separately from the base element and be, for example, part of the cover plate and / or part of a mobile electronic device.

    In order to improve the contact between the cooking battery element 12a and the support unit 10a, the support unit 10a further comprises at least one support elevation 14a, 16a. In this case, the support unit 10a comprises several, for example, four, support elevations 14a, 16a, where, for reasons of clarity, in figure 2 only two of the support elevations 14a, 16a are accompanied by reference symbol The support elevations 14a, 16a are essentially of the same construction. The 30 lifting elevations 14a, 16a are arranged on the same side of the base element 20a, namely, the side of the base element 20a directed towards the cooking battery element 12a in the heating operating state, and are arranged distributed by entire base element 20a. The support elevations 14a, 16a are associated with the same cooking battery element 12a. Here, the support elevations 14a, 16a are provided for contacting the cooking battery element 12a. However, the support unit could also present as an alternative exactly one support elevation or at least three support elevations. In addition, it is conceived that at least two support elevations are shaped differently from each other.
     40
    Next, a support elevation 14a of the support elevations 14a, 16a is described in more detail with reference to Figures 3 and 4, where the following description can also be applied to the other support elevations 14a, 16a, since the construction of the support elevations 14a, 16a is at least essentially the same.
     Four. Five
    The support lift 14a is made as a local support lift and with a hemispherical shape, and is made elevated with respect to the base element 20a. In addition, the support elevation 14a has a height with respect to the base element 20a of at least 0.5 mm and a maximum of 3 mm. In addition, the support elevation 14a has a length of its main extension and / or a maximum diameter of 20 mm in the plane parallel to the plane of the main extension of the base element 20a. In this case, the length of the main extension and / or the diameter of the support elevation 14a amounts to between 10 mm and 15 mm. In addition, the support elevation 14a is disposed midway between the center of the base element 20a and the outer flange of the base element 20a.
    The support lift 14a is made at least partially flexible and is composed of a thermally conductive material. In this case, the support elevation 14a is composed of a thermally conductive silicone. The 14th support elevation here has a thermal conductivity of at least 4 W / (m ∙ K). Therefore, the support elevation 14a is partially or completely composed of a material that differs from the material of the base element 20a. Alternatively, the support elevation could have a different shape of the hemispherical shape and / or be composed of a different material, for example, a ceramic. In this case, it is also conceived that the support elevation is stable. Likewise, it is conceived that at least one support elevation is arranged in the center of the base element. 10

    The cooking field device further comprises at least one temperature sensor 22a (see Figures 3 and 4). In this case, the cooking field device comprises several, by way of example, four temperature sensors 22a, where, for reasons of clarity, only one of the temperature sensors 22a is represented in the 15 figures and is accompanied by reference symbol The temperature sensors 22a are at least essentially of the same construction. Each of the temperature sensors 22a is associated here with one of the support elevations 14a, 16a.

    Next, a temperature sensor 22a of the temperature sensors 20a 22a is described in more detail with reference again to Figures 3 and 4, where the following description can also be applied to the other temperature sensors 22a, since the construction of The temperature sensors 22a is at least essentially the same.

    The temperature sensor 22a is made as an NTC resistor and is associated with the support elevation 25a 14a. In addition, the temperature sensor 22a is disposed in the area of the support elevation 14a, in this case, in a hollow space 24a of the support unit 10a which may be filled with a thermally conductive material 26a, for example, a thermally conductive paste . The temperature sensor 22a is embedded in the support unit 10a. In the present case, the temperature sensor 22a is directly integrated in the support elevation 14a, so that an advantageously accurate and / or accurate temperature measurement can be achieved. The temperature sensor 22a is here arranged such that the minimum distance between the temperature sensor 22a and the cooking battery element 12a amounts to a maximum of 3 mm and, preferably, a maximum of 1.5 mm. However, the temperature sensor could also be made as an alternative as a PTC resistor and / or be embedded in the base element. In addition, it is conceived that an additional thermoconducting material is dispensed with. Likewise, the temperature sensor could be integrated in the shape drag support unit.

    The cooking field device further comprises at least one magnetic unit 28a 40 (see Figures 3 and 4). In this case, the cooking field device comprises several, by way of example, four magnetic units 28a, where, for reasons of clarity, only one of the magnetic units 28a is represented in the figures and is accompanied by a reference symbol . The magnetic units 28a are at least essentially of the same construction. Each of the magnetic units 28a is here associated with one of the support elevations 14a, 16a.
    Next, a magnetic unit 28a of the magnetic units 28a is described in more detail with reference again to Figures 3 and 4, where the following description can also be applied to the other magnetic units 28a, since the construction of the magnetic units 28a It is at least essentially the same. fifty

    Magnetic 28a is arranged here such that, when the support elevation 14a is perpendicularly observed, it is arranged below the temperature sensor 22a. In this case, the temperature sensor 22a is therefore disposed between the magnetic unit 28a and the cooking battery element 12a in the heating operating state. The magnetic unit 28a is intended to provide a magnetic holding field for the cooking battery element 12a. For this, the magnetic unit 28a comprises at least one magnetic element 30a, in this case, it comprises exactly one magnetic element 30a. The magnetic element 30a is made as a permanent magnet, in this case, as a rare earth magnet, and is intended to exert an attractive force on the cooking battery element 12a and, thus, improve the contact between the support elevation 14a and the 10 cooking battery element 12a, whereby the temperature measurement can be further improved. However, alternatively, the magnetic unit could also have several magnetic elements, preferably made as permanent magnets and / or embedded in a support elevation. In addition, it is conceived that the magnetic unit is made as a magnetic particle and integrated in the material of the support unit. 15 Likewise, the magnetic unit could be arranged in a hollow space of the support unit. It is also conceived that the magnetic unit is completely dispensed with.
