The filler material can be easily integrated into the base material.
    The base material could be, for example, a metal. Preferably, the base material is a nonmetal. In this way, it is possible to achieve particularly advantageous illumination properties of the base material.

    35
    advantageously, 50 pm maximum, preferably 10 pm maximum and, particularly preferably, 1 pm maximum. When at least one container is opened in which the filling material is disposed, the filling material that is in the operational state at least granular in shape flows outward from the container. Advantageously, it is possible to freely select and / or add particular grains from among multiple grains.

    In addition, it is proposed that the filler material be a metal oxide, whereby a high strength of the filler material can be achieved in particular in an oxygen-rich environment and, coupled with it, that the filler material can be handled with ease and / or without complications.
    It is also proposed that the filler material be an aluminum oxide. The filling material is provided to withstand high temperatures, so that the filling material is prevented from deteriorating. Thus, an economic realization can be achieved.
    The cooking field plate could present in the partial area, for example, a cavity that in the assembled state could be filled to a large extent or completely with the layer element. Preferably, the cooking field plate has in the partial area at least one projection, which is surrounded and, advantageously, covered, largely or completely by the layer element in the assembled state. The projection has an approximate or exactly semi-spherical conformation and a diameter of approximately or exactly 2 mm. The cooking field plate has in the partial area at least two, preferably, at least three, advantageously, at least five and, preferably, more projections. The projections are arranged in a regular pattern and, advantageously, in the form of a matrix, and are arranged at least essentially evenly distributed throughout the lower side of the cooking field plate. In this way, high mechanical hardness and / or high mechanical strength can be achieved.
    In addition, it is proposed that the layer element present in the partial area a material thickness of at least the height of the projection with respect to a base body of the cooking field plate. The cooking field plate has at least the base body, which has an approximate or exactly parallelepipedic and / or plate-shaped conformation. The projection is attached to the base body and protrudes from it. The height of the projection is oriented approximately or exactly perpendicular to the nearest surface of the base body. The closest surface of the base body is oriented approximately or exactly parallel to the

    35
    main extension plane of the base body and arranged next to the lower side of the cooking field plate. The height of the projection corresponds roughly or exactly with the radius of the projection. The material thickness of the layer element in the partial area is oriented approximately or exactly perpendicular to the closest surface of the base body. Thus, a simple arrangement of the layer element can be achieved next to the partial area of the lower side of the cooking field plate.
    The layer element and the cooking field plate could have different indices of refraction, which could, for example, achieve a better light scattering. Preferably, the layer element and the cooking field plate have at least comparable indexes of refraction. The term "at least comparable" refractive indices includes the concept of refractive indices that are comparable or equal. The expression "comparable" refractive indices includes the concept of refractive indices in which the magnitude of the difference of the refractive indices, specifically, the magnitude of the difference of the refractive index of the layer element and the refractive index of the cooking field plate, rise to a maximum of 0.5, preferably, a maximum of 0.3, advantageously, a maximum of 0.2, particularly advantageously, a maximum of 0.1, preferably, at 0.05 at most and, particularly preferably, at 0.02 at most. The layer element and the cooking field plate each have a refractive index between 0.5 and 2.5, preferably between 0.75 and 2.25, advantageously, between 1 and 2 and, preferably, between 1.25 and 1.75. The refractive index of the layer element and the refractive index of the cooking field plate are approximately or exactly the same. The layer element and the cooking field plate each have a refractive index of approximately or exactly 1.5. Thus, an optimal and / or uniform light scattering is possible and, in addition to this, a particularly advantageous illumination.
    Likewise, it is proposed that the cooking field device has at least one approximate or exactly point-shaped light source, where the layer element is intended to disperse largely or completely at least in a state of operation at least the collimation of light beams coming out of the light source. The light source could present, for example, at least one laser. Advantageously, the light source has at least one LED (light emitting diode) and / or at least one OLED (organic light emitting diode). The light source is intended to emit electromagnetic radiation, specifically visible light, in the form of collimation of light beams. The layer element is intended to transform the collimation of

    beams of light emitted by the light source in diffuse electromagnetic radiation, specifically, in diffused light. The term "collimation of light beams" includes the concept of multiple light beams oriented approximately or exactly in parallel with each other. In this way, uniform illumination can be achieved. Likewise, the light source in the form of Point is visible when observing from the top side of the cooking field plate.
    It is possible to achieve particularly advantageous lighting properties by means of a cooking field, in particular, by an induction cooking field, with at least one cooking field device according to the invention, in particular, with at least one cooking field device. by induction according to the invention.
    The advantageous lighting properties can be increased to a greater extent by a process for the manufacture of a cooking field device according to the invention, in particular, of an induction cooking field device according to the invention, where the layer element is partially or completely manufactured by mixing at least one base raw material and at least one filling raw material and then be arranged next to the partial area of the lower side of the cooking field plate. The layer element is hardened after being arranged next to the partial area of the lower side of the cooking field plate. Following the hardening of the mixture consisting of the base raw material and the filling raw material, the layer element is largely or completely translucent. As an example, the layer element may not become largely or completely translucent until it hardens. In addition to the physical state, at least one chemical property of the layer element could be modified during hardening. Alternatively, the mixture of the base raw material and the filling raw material could already be translucent to a large extent or completely before hardening.

The partial area 16 extends largely on the lower side 18 of the cooking field plate 12, in particular, practically all the lower side 18 of the cooking field plate 12, with the exception of another partial area of the lower side 18 of the cooking field plate 12, in which the user interface 34 is arranged .

    The filling material is made of the filling raw material. The filling raw material is made at least in granular form. The grains of the filling raw material have a grain size between 0.4 pm and 0.9 pm.
    In the procedure, a certain amount of the filling raw material is weighed. The determined quantity of the filling raw material is calculated based on the relationship between the base material and the filling material to be achieved. The heavy stuffing raw material is ground. The size of the grains of the filling raw material is reduced by grinding the filling raw material. The filling raw material is ground until the grain size of the filling raw material has a value between 0.4 pm and 0.9 pm. The filler material is produced by grinding the filler raw material. Thanks to the grain size of the filler material that is achieved when the filler raw material is milled, when the base raw material and the filler raw material are mixed, the formation of an aggregate can be avoided and / or a mixture can essentially be achieved homogeneous between the base raw material and the filling raw material.
    In the procedure, a certain amount of the basic raw material is weighed. The determined amount of the base raw material is calculated based on the relationship between the base material and the filling material to be achieved. The heavy base raw material is introduced into a container.
    Directly after the introduction of the heavy base raw material into the container, the ground filler raw material is added to the heavy base raw material. Next, the mixture consisting of the base raw material and the filling raw material is removed by mixing intensively and / or for a long time.

    The mixture consisting of the base raw material and the filling raw material in the present embodiment shows a high density as a result of the viscosity of the base raw material and / or the percentage of the filling raw material in the matter base bonus.
    Following the intermingling and, in particular, the removal, the base raw material and the filling raw material, the layer element 14 is arranged next to the partial area 16 of the lower side 18 of the cooking field plate 12. As a consequence of the high density of the mixture composed of the base raw material and the filling raw material, when the layer element is arranged next to the partial area of the lower side of the cooking field plate, a part of the mixture could be lost , for example, when residues remain in the container, which could be taken into account when calculating the necessary quantities.
    The layer element 14, that is, the mixture consisting of the base raw material and the filling raw material, is distributed evenly over the partial area 16 of the lower side 18 of the cooking field plate 12. Next , the layer element 14 arranged next to the partial area 16 is hardened. For hardening, the cooking field plate 12 and the layer element 14 disposed on the cooking field plate 12 are arranged in an essentially dry place for approximately 24 hours at room temperature, which amounts to approximately 23 ° C.
