    If the clamping element and the compensation element are identical to each other, the components and thus the costs can be reduced.
    In addition, it is proposed that the clamping element and / or the compensation element be grooved. The groove may have a width of between 0.5 mm and 8 mm, preferably between 1 mm and 7 mm and, more preferably, between 1.5 mm and 6 mm.

Regardless of manufacturing tolerances, the ferrite element has an essential or totally constant material thickness and / or thickness. The expression material thickness and / or "essential or totally constant" thickness of an object includes the concept of a material thickness and / or thickness that differs from the material thickness and / or average thickness across the object by 10% as maximum, preferably, at 5% maximum and, more preferably, at 2% maximum, thus reducing the complexity of the ferrite element and increasing the efficiency of the heating power of the device of cooking range, since the distance between the heating coil and the ferrite element can be minimized.
    If the compensation element has at least one ferrite support element that is provided to press the ferrite element against the coil support, it is possible to advantageously compensate the manufacturing tolerances and at the same time achieve high stability. In this case, it is advantageously possible to press ferrite elements against the coil holder securely with a reduced material thickness and / or thickness compared to a reference material thickness and / or reference thickness. The term "ferrite support element" includes the concept of an element that is intended to be in contact with and / or support the ferrite element in the assembled state. Here, the ferrite support element is advantageously realized as an elevation rectangular, circular, oval, with the shape of an outer lateral surface of a cylinder and / or a pyramidal trunk, relative to the compensation element and / or the clamping element Advantageously, the ferrite support element is partially composed or completely, preferably, largely or completely and, more preferably, by a ceramic and / or a plastic material, in particular, a high temperature resistant plastic, preferably a liquid crystalline polymer (LCP) and / or, more preferably, a polyphenylene sulfide (PPS) As an alternative, it is conceived that the ferrite support element is partially or completely composed of an elastic element and / or deformable Here, the ferrite support element can be made by way of example as a polymer, as an elastomer, as a silicone element and / or as a spring, in particular, as a compression spring.

    more preferred, four or more ferrite support elements. Advantageously, the ferrite support element and the compensation element are made in one piece and, particularly preferably, the ferrite support element, the compensation element, and the fastener element are made in one piece.
    In a particularly preferred embodiment of the invention, it is proposed that the ferrite element be fixed to the coil support only in drag and / or force, in particular, indirectly, and not in union of material, by for example, with a silicone adhesive and / or with an adhesive tape. Thus, the duration of the assembly can be reduced, since a hardening of an adhesive that requires a lot of time and / or is completely dispensed with is not necessary.
    In addition, a method is proposed with a cooking field device, in particular, with an induction cooking field device, which has at least one coil support for supporting one or more heating coils, at least one heating element. ferrite, and at least one fastener element to be joined with the coil support and to support the ferrite element, where the fastener element has at least one compensation element, and through the compensation element the manufacturing tolerances are compensated of the ferrite element, in particular, with respect to the direction of the normal to the main extension plane of the ferrite element.

The cable duct channel 48 It is intended to guide various supply lines in the assembled state. The support roll 30 and the side delimiter elements 32, 34 delimit a heating coil housing area 36 partially or completely. Alternatively, a first and / or a second lateral delimiter element could also have the same shape and / or a different shape in top view.
    On the other hand, the coil support 10 has a first fixing element 20 (see in particular Figure 5), which is arranged centrally and concentrically next to the second lateral delimiter element 34. The first fixing element 20 is arranged on one side of the second lateral delimiter element 34 opposite the support roll 30 and / or the first lateral delimiter element 32. In the present case, the first fixing element 20 is made as the first bayonet closure element. As an alternative, it is conceived to make a first fixing element as a fitting element and / or threaded element.
    The cooking field device further comprises a heating coil 12 (see Figures 6 and 7), specifically, the heating unit 28 comprises the heating coil 12, which is exactly made up of a heating line and has 20 you turn In top view, the heating coil 12 has a circular shape and, in the assembled state, is arranged in the heating coil housing area 36, whereby the coil holder 10 is provided to support the heating coil 12. Here, the heating line is wound around the support roll 30, whereby the heating coil 12 forms. In addition, the heating coil 12 comprises two or more connection contacts (not shown), which are intended to supply electric current to the heating coil 12, which is intended to heat a cooking battery through effects of eddy currents and / or magnetic inversion.

The ferrite element 14 is composed of a high ferrite material. yield and, in the present case, it is composed of 3C90, although as an alternative it is conceived that a ferrite element is composed of 3C91, 3C92, 3C93, 3C94, 3C95, 3C96 and / or 3C97. In addition, the ferrite element 14 is made in one piece and essentially or
    5
    10

    30
    totally laminate Regardless of the manufacturing tolerances, the ferrite element 14 is flat, so it has a material thickness at least essentially constant, in the present case, approximately 5 mm. In top view, the ferrite element 14 has an alveolar shape and, in the present case, an average diameter of approximately 75 mm. In addition, the ferrite element 14 has a central drain 38 which in a top view has a circular shape. The recess 38 has a diameter between 10 mm and 25 mm, in the present case, approximately 20 mm. In addition, the ferrite element 14 is grooved, whereby it has a groove 40 that extends from the central recess 38 in a radial direction to a marginal area of the ferrite element 14, and has a width of approximately 12 mm.
    In addition, the cooking field device comprises a clamping element 16 (see Figure 4), specifically, the heating unit 28 comprises the clamping element 16, which has a compensation element 18. In the present case, the holding element 16 and the compensation element 18 are identical to each other, so they form the same component. However, as an alternative it is also conceived that a clamping element and a compensation element are made in two pieces, in which case the compensation element could be made as an example as an elastic element, in particular as a polymer, as an elastomer , as a silicone element and / or as a spring, and preferably joined in one piece, for example, in union of material, with the clamping element, in particular, with one side of the clamping element directed towards a coil support.
    The shape of the fastener 16 is at least essentially stable. In addition, the holding element 16 is composed of polyphenylene sulfide, and is made in one piece, in the present case being composed of a single fragment. Likewise, the clamping element 16 has a constant material thickness, which in this case amounts to approximately 0.5 mm. In top view, the clamping element 16 has an alveolar shape. In the present case, the clamping element 16 has an average diameter of approximately 75 mm. In addition, the clamping element 16 has another central recess 42, which has an approximate or exactly circular shape in top view, and an average diameter between 10 mm and 25 mm, in the present case, approximately 20 mm. In addition, the clamping element 16 is grooved, whereby it has another groove 44, which extends from the other recess 42 in a radial direction to a marginal area of the clamping element 16, and has a width of approximately 5 mm.

    The holding element 16 is provided to support the ferrite element 14, as well as to join it with the coil support 10 and press it against it. For this, the fastening element 16 has a second fixing element 22, which is made corresponding to the first fixing element 20. The second fixing element 22 delimits the other emptying 42, so it is centrally arranged and concentric next to the fastener element 16. In the present case, the second fastener element 22 is made as a second bayonet closure element. As an alternative, it is conceived that a second fixing element is made as a fitting and / or threaded element. The complementary fixing elements 20, 22 are provided to fix the fastening element 16 to the coil support 10, whereby the fastening element 16 and the coil support 10 are connected to each other by means of a bayonet joint in the assembled state , grabbing trailing connection elements in the form of the second fixing element 22 of the clamping element 16 behind behind trailing connection elements in the form of the first fixing element 20 of the coil holder 10 when the clamping element 16 is rotated and / or the coil support 10. Likewise, the complementary fixing elements 20, 22 are provided to fix the ferrite element 14 indirectly to the coil support 10. Here, the ferrite element 14 is fixed to the coil support 10 only in drag of form and / or force, and not in union of material. In the present case, the entire heating unit 28 has no adhesive.
    Likewise, the clamping element 16 and / or the compensation element 18 has four ferrite support elements 24, which are arranged next to one side of the clamping element 16 directed towards the coil support 10. In the present case, The ferrite support elements 24 are joined in one piece with the holding element 16, whereby they are composed of polyphenylene sulfide. Likewise, the ferrite support elements 24 are uniformly distributed on a surface of the fastener element 16, and are made as elevations with respect to the fastener element 16. In the present case, the ferrite support elements 24 are rectangular . The ferrite support elements 24 are provided to press the ferrite element 14 against the coil support 10. However, at least one ferrite support element could also be alternatively composed of another material, namely, plastic, and / or be made as an elastic element, in particular, as a polymer, as an elastomer, as a silicone element and / or as a spring.
    In addition, the clamping element 16 has at least one fixing element 46, in the present case, four fixing elements 46. The fixing elements 46 are
    arranged next to one side of the clamping element 16 opposite the coil holder 10. In

    In the present case, the fixing elements 46 are joined in one piece with the holding element 16, whereby they are composed of polyphenylene sulfide. Likewise, the fixing elements 46 are uniformly distributed on another surface of the holding element 16 (see in particular Figure 5), and are made approximately or exactly cylindrically. In addition, the fixing elements 46 are elongated and have a main extension direction that is arranged perpendicularly to the main extension plane of the holding element 16. In the present case, two of the fixing elements 46 are made as fitting elements, and are provided to fix the holding element 16 and / or the ferrite element 14 and / or the coil support 10 to a support unit (not shown). Therefore, regardless of the fixing elements 46, the fastening element 16 is at least essentially laminar. As an alternative, it is conceived that all fasteners are made as fitting elements. In addition, a fastener element could have a different amount of fasteners, for example, at least one fastener and / or at least two fasteners.
    Figures 5, 6 and 7 show the coil support 10, the ferrite element 14, and the clamping element 16 and / or the compensation element 18 in a partially assembled state (see Figure 5), in a fully state mounted (see figure 6), and in a sectional view along line VII-VII of figure 6 (see figure 7).
    In particular, Figure 6 shows that the holding element 16, the ferrite element 14, and the coil support 10, in particular, the second lateral boundary element 34, have the same contour and the same average diameter in top view. In addition, the ferrite element 14 is disposed in the assembled state between the clamping element 16 and the coil support 10, in particular, the second lateral delimiter element 34.
    In the present case, the clamping element 16 and / or the compensation element 18 and the ferrite support elements 24 are provided to compensate for the manufacturing tolerances that occur during the manufacture of the ferrite element 14, which can rise to several hundred pm. Here, the other groove 44 of the clamping element 16 is provided to reduce the flexural strength of the clamping element 16. In this case, the clamping element 16 is at least partially elastic, whereby the position of a marginal area of the holding element 16, as indicated in figure 7, can vary at least 2 mm relative to the position of a central area of the holding element 16 at least in the direction perpendicular to the main extension plane of the element of clamping 16. In this way, tolerances can be effectively compensated
    of fabrication of the ferrite element 14, in particular, without causing the relatively inelastic material of the fastening element 16 to break. In addition, despite the possible manufacturing tolerances, the ferrite support elements 24 are provided to press the element of Ferrite 14 against coil holder 10 in a safe manner.
    5 Furthermore, through the ferrite support elements 24 it is possible to press against the coil support 10 the ferrite elements with a reduced material thickness and / or thickness in comparison with a reference material thickness and / or reference thickness.
