    Through the state of the art, an induction cooking field with light-emitting diodes is already known to indicate the active cooking zones or to emit information related to its state, which illuminate through a cooking field plate from below. . The light-emitting diodes are arranged here next to or between cooking zones in the horizontal direction to avoid excessive heating, so that the light-emitting diodes can only illuminate through partial areas of the cooking field plate, outside of the cooking zones. cooking. In addition, a magnetic field generated by induction heating units of the induction cooking field prevents the effective and reliable use of known matrix configurations of the light-emitting diodes in the area above the cooking zones, in particular as a consequence of the induction of circular currents. Thus, only a partial area of the cooking field can be used to display light signals. The extension of the area that can be used for this purpose to areas not usable so far, in particular, within a cooking zone, can advantageously open multiple new possible control and indicator devices.

    In addition, it is proposed that the heating unit be considerably distanced from the cooking field plate in the normal direction. In this way, an intermediate space can be advantageously formed, which can be provided to at least partially house the light unit. In addition, the intermediate space between the cooking field plate and the heating unit may form a cooling channel to cool a component disposed in the intermediate space and / or adjacent to the intermediate space.

At least one, preferably each luminous element of the group of luminous elements is electrically connected in parallel with another luminous element of the group of luminous elements. The expression "row of luminous elements" includes the concept of an essentially rectilinear arrangement of luminous elements.
    Furthermore, it is proposed that the light unit has at least one other group of luminous elements arranged in at least one other row, so that an even more complex indicator signal can be advantageously displayed.

Preferably, each luminous element of the other group of luminous elements is electrically connected in parallel with another luminous element of the other group of luminous elements.

    If the light unit has multiple light elements that are arranged in at least one matrix, an even more complex indicator signal can be advantageously displayed, so that flexibility can be advantageously increased. In this way, the multiple luminous elements can advantageously form a surface indication, which can advantageously increase the visibility of the indication. The term "matrix" includes the concept of a two-dimensional arrangement of luminous elements. Preferably, the matrix has a regular arrangement of luminous elements. The regular arrangement is configured along at least one spatial direction, preferably, along two spatial directions. As an example, the regular arrangement can be configured as a uniform and / or offset grid pattern. It is conceived, for example, that the matrix is made by a parallel arrangement of several groups of luminous elements electrically connected in parallel. The term "multiples" includes the concept of an amount of at least 10, preferably, at least 30, more preferably, at least 50 and / or, particularly preferably, at least 100 light elements. The luminous elements of the matrix are electrically coupled to each other and, preferably, are connected to each other in parallel, preferably without forming conductive loops. In this way, the influence of the voltages and electric currents applied to the luminous elements through the alternating electric fields, in particular, through an induction heating unit can be advantageously reduced. In addition, it is conceived that the die extends over a large part of the surface of the cooking field plate. For this, the matrix has a surface extension that corresponds to at least 51%, preferably, at least 66%, preferably, at least 75% or, particularly preferably, with 90% as minimum of the surface extension of the cooking field plate parallel to the main extension plane of the cooking field plate.

    Advantageously, the cooking field device has a control unit that is intended to emit information by means of the light unit. Thus, the ease of use can be advantageously increased, for example, the luminous signals of the luminous elements can be used advantageously in a directed and localized manner to communicate to the user an operating parameter. By way of example, it is conceived that advantageously only information about areas of the cooking field plate not covered, for example, with a cooking battery, is shown. In addition, for example, the temperature distribution by means of a


    chromatic gradation or by means of a localized indication of temperature values, specifically, in hot areas.

    If the light unit configures at least one display, complex information in the form of images can be advantageously transmitted to the user, so that the comprehensibility and clarity of an indication can be advantageously improved. As an example, animations, videos and / or images can be advantageously displayed through a display. In this way, the ease of use can be increased to a greater extent. It is conceived that a large part, preferably, the entire cooking field plate, is intended to be used as a display. The term "large portion of the cooking field plate" includes the concept of at least 51%, preferably, at least 66%, preferably, at least 75% or, particularly preferably, at least 90% of the surface extension of the cooking field plate parallel to the main extension plane of the cooking field plate.

By means of a parallel connection of the luminous elements, it is advantageously possible to keep the influence of the voltages and electric currents applied to the luminous elements through the alternating electric fields, in particular, through an induction heating unit, reduced. In addition, it is conceived that all the luminous elements, in particular, all the luminous elements belonging to at least one group of the luminous unit, are connected in parallel.
    In addition, it is proposed that the light unit be provided to emit at least two, preferably three, light spectra considerably different from each other. Of this


    mode, a polychrome indication may be advantageously made possible with the possibility of changing color, thereby increasing the ability to recognize the particular indication and / or indicating signals. In addition, thanks to the multiple possible colors of the light unit, the combination of possible indicator signals can be increased, so that the field of application and / or flexibility can be advantageously increased. The term "light spectrum" includes the concept of a distribution function of a physical variable, namely, an energy, a wavelength and / or a frequency of photons or light waves. The term "light spectrum" includes the concept of the spectrum or distribution of light waves or photons emitted by the light unit during operation. Preferably, at least one light spectrum has a maximum with a wavelength and / or energy and / or frequency, which makes the emitted light appear red and / or green and / or blue for the receiver and / or the observer . Preferably, the light unit is intended to emit at least one red, one green and / or one blue light. Particularly preferably, the light unit is intended to emit at least one, in particular, all possible combinations of red, green and blue light. The expression "light spectra considerably different from each other" includes the concept of light emissions from the light unit whose functions of energy distribution, wavelength, or frequency have different maximums. The maxima of the energy distribution function differ from each other by at least 0.1 eV. The maximums of the wavelength distribution function differ from each other by at least 30 nm. The maxima of the frequency distribution function differ from each other by at least 30 THz. It is conceived that the light unit has at least one light element that can emit at least two, preferably three, light spectra considerably different from each other. Alternatively or additionally, it is conceived that the light unit has at least two light elements, preferably multiple light elements, each of which emits light spectra considerably different from each other when activated by the control unit.
    Likewise, it is proposed that the cooking field device has at least one support unit, which is thermally decoupled at least to a large extent from at least the cooking field plate and is provided to support the light unit. The support unit is flat. Preferably, the support unit has a horizontal surface extension parallel to the main extension plane of the cooking field plate, which corresponds to at least 30%, preferably, at least 50%, of more preferably, with at least 70% or, particularly preferably, with at least 90% of the surface extension of the plate

The distance of the support unit from the cooking field plate in the normal direction is at least 5 mm, preferably at least 10 mm, more preferably, at least 20 mm or, particularly preferred way, at least 30 mm. The distance of the support unit from the heating unit in the normal direction is at least 5 mm, preferably at least 10 mm, more preferably, at least 20 mm or, particularly preferred, at least 30 mm. The distance of the support unit from the cooking field plate in the normal direction is at least 30%, preferably at least 60% or, more preferably, at least 100% greater than the distance of the support unit from the heating unit in the normal direction. The expression that a constructive unit is “largely thermally decoupled” from another constructive unit includes the concept that the constructive unit does not have direct constructive unions with the other constructive unit, which has a thermal conductivity greater than 1 W / mK, preferably, greater than 0.5 W / mK, more preferably, greater than 0.25 W / mK or, particularly preferably, greater than 0.1 W / mK.
    Likewise, a cooking field is proposed with the cooking field device.

By the second connection arrangement 36c ', a group 32 of luminous elements 30 is connected in parallel with 50% of all other groups of light elements 30 that are not part of the first connection arrangement 36c.
    In the connection arrangement 36d shown in Figure 3d, every three groups 28, 32, 76 of luminous elements 30 of a light unit 20 are connected in series. By means of the serial connection of the three groups 28, 32, 76, a triple group 78 is generated. All the luminous elements 30 of the triple group 78 are connected in parallel with each other. Multiple triple groups 78 are connected in parallel with each other.
    In the connection arrangement 36e shown in Figure 3e, all groups 28, 32, 76 of luminous elements 30 of a light unit 20 are connected in series. All luminous elements 30 of all groups 28, 32, 76 are connected in parallel with each other.
    Alternatively and / or additionally, it is conceived that the person skilled in the art will resort to the combination of connection arrangements 36a-e and / or another appropriate electrical interconnection of the light elements 30.


    In a procedure for putting into operation a cooking field device with at least one cooking field plate 10 and with at least one light unit 20, which is intended to illuminate at least a partial area of the field plate of cooking 10, in at least one step of the process 80 (see Figure 4), a
    5 luminous unit 20. Here, the cooling air flows alongside the luminous elements 30 of the luminous unit 20. The luminous elements 30 emit heat to the cooling air as it flows along with them. The heated cooling air is removed from the luminous elements 30 by means of a circulation unit 52, thus generating a heat current that moves away from the luminous elements 30.
