In at least the operating state, the configuration unit connects the second configuration input electrically conductively with the second configuration output and with the third configuration output and, additionally, with the first configuration output, depending on its activation by the control unit. Thus, great flexibility can be achieved.

In addition, it is proposed that the first configuration input be electrically conductive exclusively with the first configuration output in the operating state. In at least the operating state, the configuration unit electrically conducts the first configuration input exclusively with the first configuration output, depending on its activation by the control unit. The second configuration input is electrically conductive only with the second configuration output in the operating state. In at least the operating state, the configuration unit electrically conducts the second configuration input exclusively with the second configuration output, depending on its activation by the control unit.

In this way, it is possible that the costs are low.

As an example, the number of heating frequency units of the power supply unit could be greater than the amount of power supply outputs. At least two heating frequency units of the power supply unit could be electrically conductively connected to exactly one of the power supply outputs, so that the power supply output It could be operated with a higher heating power and / or in an enhancer mode. Preferably, the amount of heating frequency units of the power supply unit is at most the same as the amount of power supply outputs. For example, the number of heating frequency units of the power supply unit could be less than the amount of power supply outputs. At least one of the heating frequency units could be optionally connectable with at least two of the power supply outputs. Particularly advantageously, the amount of heating frequency units of the power supply unit is the same as the amount of power supply outputs, which makes optimum heating possible. In particular, each of the heating frequency units could be electrically conductively connected to exactly one of the power supply outputs. Thus, it can be achieved that the quantity of components is reduced and / or that the costs are low.

In at least the operating state, the assignment unit connects at least one of the assignment inputs optionally with at least two of the assignment outputs in an electrically conductive manner, depending on its activation by the control unit. In this way, the assignment outputs can be assigned to the assignment entries with flexibility, thus achieving multiple possible combinations and / or great flexibility.

In addition, it is proposed that at least the first assignment input of the assignment inputs be electrically conductive and, in particular, electrically conductively connected, exclusively with at least the first assignment output of the assignment outputs in The operating status. Additionally, at least the second assignment input of the assignment inputs could be electrically conductively connected and, in particular, electrically conductively connected, exclusively with at least the second assignment output of the assignment outputs in The operating status. At least the third of the assignment inputs could be electrically conductive and, in particular, electrically conductively connected, exclusively with at least the third assignment output of the assignment outputs in the state of functioning. In at least the operating state, the assignment unit connects the first and / or the second and / or the third assignment input optionally with the corresponding one, in particular, the first and / or the second and / or the third, of the assignment outputs electrically conductive, depending on their activation by the control unit. In this way, a univocal and / or fixed assignment of the assignment inputs to the assignment outputs is made possible, so that a simple and / or uncomplicated and / or reliable realization can be achieved with little tendency to errors.

Likewise, it is proposed that the cooking field device has at least one control unit, which electrically conductively connects at least one of the power supply outputs with at least one heating unit in the operating state, which heat a heating zone, depending on the heating zone configuration and / or the cooking battery configuration.

Alternatively or additionally, the heating zone configuration could be a property of the heating zone itself, such as the size and / or shape of the heating zone. The heating zone configuration could be, for example, the time sequence in which the heating zones are formed and / or formed. Alternatively or additionally, the heating zone configuration could be the spatial proximity of at least two heating zones with respect to each other. Also alternatively or additionally, the heating zone configuration could be, for example, the absolute and / or relative interconnection of heating units which, in at least one operating state, could form arranged heating zones adjacently and / or the coupling sequence of heating units that in at least one operating state could form heating zones arranged adjacently. The term "cooking battery configuration" includes the concept of a property that characterizes the cooking battery arranged on the cooking field to be heated by it.

The heating zone setting could correspond to a cooking battery configuration. Alternatively, the heating zone configuration could, for example, have at least one heating zone that could be provided for heating at least two cooking batteries. In this way, it is possible to react flexibly to the heating zone configuration and / or given cooking battery configuration, which makes it possible for the convenience of use to be greater.

In at least one operating state, the control unit could, for example, electrically connect exactly one of the configuration outputs with at least two heating units adjacent to each other, which heat a common heating zone. Preferably, the control unit conductively connects electrically in the operating state at least two and, preferably, at least three of the power supply outputs with at least two and, preferably, with at least three heating units adjacent to each other, which heat a common heating zone. Thus, it is possible to heat even large heating zones and / or cooking batteries optimally and / or with sufficient heating power, whereby a short cooking time and / or optimal cooking results can be achieved.

In the case of a heating zone configuration that could have exactly one very large heating zone and that could be intended to heat exactly one very large cooking battery, the control unit could connect the units in at least one operating state. of heating that heat the heating zone with at least two and, advantageously, with at least three electrically conductive power supply outputs.

In the case of a heating zone configuration that could have at least two heating zones of different sizes and that could be provided for heating at least two different-sized cooking batteries, the control unit could be provided to connect in a manner electrically conductive heating units that heat the largest of the heating zones with a greater amount of power supply outputs than the heating units that heat the smaller of the heating zones.

In at least one operating state, the control unit could, for example, electrically connect at least two of the configuration outputs with a single heating unit and operate the heating unit in the operating state in one mode. enhancer and / or with greater heating power. Preferably, the control unit prevents in the operating state that at least two of the power supply outputs are electrically conductively connected to exactly one single heating unit. In at least one operating state, the control unit assigns at most one of the configuration outputs and / or at most one of the heating frequency units of the power supply unit simultaneously to at least one single heating unit . In at least one operating state, the control unit could assign at least two different configuration outputs and / or at least two different heating frequency units to at least one single heating unit in at least two directly consecutive time intervals , which could be part of a single period duration. Thus, overloading of the heating units can be avoided, and a lasting embodiment can be achieved in this way.
