    [0005]
    [0006] Through the state of the art, cooking field devices having multiple heating units with each a heating element are already known. Each of the heating units is connected to at least one cable with a power supply board. The cables have different lengths depending on how far apart the heating units of the power supply board are. In this way, when mounting the cooking field device, it is necessary to pay close attention and to act with extreme care, since each of the heating units must be arranged in the position provided for the corresponding heating unit with respect to the power supply plate and / or the appropriate cables must be used accordingly.
    [0007]
    [0008] The present invention solves the technical problem of providing a generic cooking field device with better properties in terms of its assembly. According to the invention, this technical problem is solved by the features of claims 1 and 14, while advantageous embodiments and improvements of the invention can be extracted from the secondary claims.

    [0011]
    [0012] By means of the embodiment according to the invention, a simple and / or quick and / or economical assembly can be achieved in the case of a high number of heating units. In particular, the heating units can be flexibly arranged in a relative position with respect to the functional plate. The unit of electrical connection that connects one of the heating units with the connection plate can be identical for each of the heating units, so that connection units configured in different ways are not necessary and, therefore, an assembly can be achieved simple and / or fast and / or economical. In a particularly advantageous manner, high efficiency is possible during heating of the cooking coil due to the low electrical losses, which can be ensured by the reduced extension of the connection unit connecting the heating units to the connection plate. Also, reduced storage can be achieved thanks to the electrical connection units made in an identical manner. In case of problems, an oversized connection unit can be excluded as a cause, so the fault search can be simplified. Thanks to the connection plate and / or thanks to the functional plate, it is possible to achieve great flexibility, since for each embodiment a plate configured in a manner corresponding to the needs can be provided.

In this way, it is possible to optimize the distance of the heating unit from the theoretical positioning position for a cooking coil defined by the cooking hob, whereby the cooking coil can be heated to a range of frequencies for this purpose and, thus, optimal cooking results can be achieved. Thanks to the spring element, the forces acting during transport can be compensated, so that the position of at least one of the heating units can be maintained with respect to the cooking field plate and, thus, an optimum coupling of the corresponding heating unit with the cooking battery resting on it.

The expression that a first unit and a second unit are made "at least partially in one piece" includes the concept that the first unit has at least one element that is also part of the second unit at the same time. The spring is made largely or completely from at least one electrically conductive material and has an electrical conductivity of at least 3 * 106, advantageously at least 107 N / mm, preferably at least 5 * 107 S / m, and particularly preferably at least 7 * 107 S / m In this way, reduced storage is possible and / or there is little diversity of building units.

    [0055] Furthermore, it is proposed that the support unit has at least one contact element, which is tinned with the connection plate. By way of example, the contacting element could be tinned with the surface of the connecting plate. Alternatively or additionally, the contacting element could be made at least partially in one piece with the gear element and could be tinned with the connecting plate in a state of at least partial engagement in the connecting plate. The term "contacting element" includes the concept of an element that defines and / or at least partially complies with an electrical contact The contacting element is made largely or completely of at least one conductive material electrically, which has an electrical conductivity of at least 103 S / m, preferably of at least 104 S / m, advantageously, of at least 105 S / m, particularly advantageously, of at least 106 S / m and, preferably, at least 107 S / m The support unit could be electrically connected to the connection plate, for example, by putting it in contact with SMD, being the development of the acronym "Surface-Mounted Device" (device mounted on the surface).

In at least one operating state, the other contacting element contacts the heating unit in an electrically conductive manner by contacting caused by crimp. Thus, it is possible to establish an electrically conductive connection in a particularly simple manner. In addition, a particularly stable electrically conductive connection is possible.
    [0056]
