    Different element with respect to the cooking field plate could be arranged next to the cooking field plate, and could be arranged in thermal contact with the cooking field plate. Preferably, the temperature compensation unit has at least one heating element in the surrounding area, which is intended to heat the cooking field plate in the surrounding area. The heating element could be, for example, part of the heating unit. Also, the heating element could form, for example, a heating conductor of the heating unit. Advantageously, the heating element is made separately from the heating unit. The heating element is arranged in the surrounding area and, in particular, in an area close to the cooking field plate. In the installation position, the heating element could be arranged under the cooking field plate in the vertical direction and at a short distance from the cooking field plate. The heating element is arranged next to the cooking field plate and in thermal contact with it. The heating element is made as a layer. The temperature compensation unit has at least one layer, which is made as a coating of the cooking field plate in the surrounding area. In this way, the temperature gradient can be adjusted and / or influenced in a particularly specific way.
    It is also proposed that the temperature compensation unit be provided to evacuate heat from the support area, whereby the maximum temperature of the cooking field plate can be reduced in a directed manner.
    The temperature compensation unit could be provided, for example, to supply the evacuated heat from the support area to the surrounding area through heat conduction by at least one different element with respect to the cooking field plate. Preferably, the temperature compensation unit has at least one heat pipe, in particular at least one heat pipe, which is intended to evacuate heat from the support area. In the installation position, the heat pipe could be arranged under the cooking field plate in the vertical direction. Alternatively or additionally, the heat pipe could be arranged next to and / or fixed to the bottom side of the cooking field plate in the installation position. As an example, the heat pipe could be arranged and / or fixed in a vertical direction in a groove on the lower side of the cooking field plate in the installation position. Alternatively or additionally, the heat pipe could be integrated largely or completely into the cooking field plate in the installation position. The heat pipe is intended to absorb heat


    by a first end of the heat pipe, and to emit it, for example, to a cooling unit and / or the environment, by a second end of the heat pipe, opposite the first end of the heat pipe in the direction of its extension longitudinal. In particular, the heat pipe is intended to transport heat in the direction of the longitudinal extension of the heat pipe using evaporation heat. The heat pipe has at least one fluid conduit, in particular, at least one capillary, and at least one fluid, which is arranged in the fluid conduit and is intended for heat transport. Also, the heat pipe is provided to absorb heat from the first end of the heat pipe by evaporating the fluid, and to emit it from the second end of the heat pipe by condensing the fluid, and to transport the fluid back to the first end of the heat pipe. In this way, the thermal load of the cooking field plate in the support area can be achieved to be small. Likewise, thermal shock states can be prevented easily.
    It is also proposed that the temperature compensation unit be arranged largely or completely under the cooking field plate in the installation position and, in particular, in the vertical direction. In this way, a protected arrangement of the temperature compensation unit can be made possible.
    In addition, it is proposed that the temperature compensation unit be arranged largely or completely above the cooking field plate in the installation position and, in particular, in the vertical direction. By way of example, the temperature compensation unit could be arranged in the installation position directly on a surface directed towards the user such as, for example, the surface of the cooking field plate and / or on a layer unit arranged on the surface of the cooking field plate. The temperature compensation unit could be arranged, for example, so that it is visible to the user. Alternatively, the temperature compensation unit could be made largely or completely as a layer, and disposed between the surface of the cooking field plate and a layer unit located on the surface of the cooking field plate , which could have, for example, at least one protective layer. As an example, the temperature compensation unit could be provided for issuing and / or representing the user a warning regarding a hotter area, in particular, regarding a high temperature and / or constituting a burn hazard for the user, in the support area and / or in the surrounding area, by means of an arrangement and / or a color and / or a design. In this way, you can


    achieve simple accessibility to the temperature compensation unit and / or simple assembly of the temperature compensation unit, in existing products.
    Likewise, it is proposed that the temperature compensation unit has at least one temperature compensation element, which surrounds the support area largely or completely with respect to a plane oriented parallel to the main extension plane of the cooking field plate. The temperature compensation element surrounds, in particular, wraps around the support area in the plane oriented parallel to the main extension plane of the cooking field plate around an angular area of at least 270 °, preferably 300 ° at least, advantageously, at least 330 ° and, preferably, at least 350 °, with respect to at least the center of gravity axis of the support area. The temperature compensation element is arranged largely or completely in the surrounding area. As an example, the temperature compensation element could be provided to heat the surrounding area, and could be made in one piece with the heating element and as an electric conductor. Alternatively, the temperature compensation element could be made as a heat conductor and intended to heat the surrounding area by heat conduction. Also, the temperature compensation element could be composed largely or entirely of silver and / or gold and / or aluminum and / or steel and / or copper and / or an alloy of the aforementioned materials. The temperature compensation unit has at least two and, advantageously, at least three temperature compensation elements that largely or completely surround the support area with respect to the plane oriented parallel to the main extension plane of the cooking field plate, and which are arranged concentrically with each other and around the support area. The temperature compensation unit is intended to adjust the temperature gradient gradually and / or continuously by means of the temperature compensation elements, and to adjust in the surrounding area temperatures of the cooking field plate that decrease in the horizontal direction The temperature reached in the surrounding area by means of the temperature compensation element could depend on the material of the temperature compensation element and / or the dimensions of the temperature compensation element. Thus, influence on the temperature gradient can be exerted in a directed manner.
    At least in the assembled state, the temperature compensation element could be arranged, for example, spaced apart and not connected with respect to the area of


    support for. Preferably, the temperature compensation unit has at least one other temperature compensation element, which thermally conducts the temperature compensation element and the support area at least in the assembled state. In the mounted state, the direction of the longitudinal extension of the other temperature compensation element is oriented approximately or exactly parallel to the horizontal direction and radially to the support area. The other temperature compensation element could be composed largely or entirely of silver and / or gold and / or aluminum and / or steel and / or copper and / or an alloy of the aforementioned materials. The temperature compensation unit has at least two, preferably, at least three, advantageously, at least five, particularly advantageously, at least eight, preferably, at least twelve and, particularly preferably, fifteen of the other temperature compensation elements, which heat conductively join each of the temperature compensation elements and the support area in the assembled state. In the assembled state, the other temperature compensation elements are arranged at least essentially evenly distributed around the support area in an approximate oriented plane or exactly parallel to the main extension plane of the cooking field plate. In this way, an optimal reduction of the temperature compensation coefficient is made possible.
    Likewise, it is proposed that the temperature compensation element and, in addition, the other temperature compensation element, have a specific thermal conductivity of at least 10 W / (m * K), preferably 50 W / (m * K) at least, advantageously, at least 100 W / (m * K), particularly advantageously, at least 200 W / (m * K), preferably at least 300 W / (m * K) at least and, particularly preferably, at least 400 W / (m * K), at 0 ° C. In this way, a particularly good heat conduction can be achieved and, coupled with it, a lasting embodiment.
    Furthermore, it is proposed that the temperature compensation element has a specific electrical conductivity of at least 104 S / m, preferably, at least 105 S / m, advantageously, at least 106 S / m, particularly advantageously, at least 10 * 106 S / m, preferably at least 30 * 106 S / m and, particularly preferably, at least 60 * 106 S / m at 0 ° C. Thus, a high electrical conductivity of the temperature compensation element can be achieved and, in addition to that, that the
