In this way, particularly high flexibility and / or optimized heating of the supported cooking battery can be provided.

In addition, it is proposed that the third heating frequency unit be assignable at a maximum percentage of 95%, preferably 90% maximum, advantageously, 85% maximum, particularly advantageously, 80 % maximum, preferably, 75% maximum and, particularly preferably, 72% maximum of the first heating units.

Thus, the costs can be low thanks to the reduced number of connection elements of the connection unit.

As an example, the percentage of the first heating units to which the third heating frequency unit is assignable could define a central area of the first partial cooking surface area. The percentage of the second heating units to which the third heating frequency unit is assignable could define, for example, a central area of the second partial cooking surface area. Preferably, the percentage of the first heating units to which the first heating frequency unit is exclusively assignable defines a marginal area, for example, a lateral marginal area and, in particular, a corner area, of the first cooking surface section. Advantageously, the percentage of the second heating units to which the second heating frequency unit is exclusively assignable defines a marginal area, for example, a lateral marginal area and, in particular, a corner area, of the second cooking surface section. In this way, heating units that are rarely in operation can be exactly assignable to a heating frequency unit, which means that low costs can be achieved.

In addition, it is proposed that at least two first heating units arranged adjacent to each other be optionally assignable in each case simultaneously to the first heating frequency unit and / or the third heating frequency unit. In particular, at least two first heating units arranged adjacent to each other could in each case be optionally simultaneously assignable to the first heating frequency unit or the third heating frequency unit, or both to the first heating unit. heating frequency as to the third unit of heating frequency. Alternatively or additionally, at least two first heating units arranged adjacent to each other could be optionally simultaneously assignable to different heating frequency units in each case.

Likewise, it is proposed that at least two first heating units arranged adjacent to each other be assignable simultaneously to the first heating frequency unit or the third heating frequency unit. The possibility of simultaneously allocating at least two first heating units arranged adjacent to each other to the first heating frequency unit and the third heating frequency unit could be ruled out. In this way, it can be achieved that the costs are low and / or that there is a reduced amount of connection elements.

Furthermore, it is proposed that the cooking field device has at least one control unit, which assigns the third heating frequency unit in at least one operating state to the part of the first heating units or to the part of the second heating units depending on the heating zone configuration and / or the cooking battery configuration. In the case of a heating zone configuration that could have exactly one very large heating zone and that could be provided to heat exactly one very large cooking battery, the control unit could assign to the heating units that heat the zone of heating at least two and, advantageously, at least three heating frequency units, in particular, the first heating frequency unit and / or the second heating frequency unit and / or the third heating frequency unit . A very large cooking battery could, for example, be partially or completely arranged on top of at least a first heating unit and at least a second heating unit and could cover a percentage of at least 50%, preferably, at least 60% and, advantageously, at least 70% of the heating units that define the first partial cooking surface area. In the case of a heating zone configuration that could have at least two heating zones of different sizes and that could be provided to heat at least two firing batteries, the control unit could assign to the heating units that heat the heating greater of the heating zones a greater amount of heating frequency units than the heating units that heat the smaller of the heating zones. The term "heating zone configuration" includes the concept of a property that in at least one operating state characterizes one or more properties of the minus a heating zone. The heating zone configuration could be, for example, the arrangement of heating zones in the variable cooking surface area in an absolute and / or relative manner with respect to at least one boundary edge of the variable cooking surface area and / or relative to at least one edge of the cooking field and / or relative to each other. 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 cooking battery configuration could be, for example, the arrangement of cooking batteries in the variable cooking surface area in an absolute and / or relative manner with respect to at least one defining edge of the variable cooking surface area and / or relative to at least one edge of the cooking field and / or relative to each other. Alternatively or additionally, the cooking battery configuration could be a property of the cooking battery itself, for example, the size and / or shape and / or material of the cooking battery. The cooking battery configuration could be, for example, the time sequence in which the cooking batteries are placed and / or placed in the variable cooking surface area. Alternatively or additionally, the cooking battery configuration could be the spatial proximity of at least two cooking batteries relative to each other. Also alternatively or additionally, the cooking battery configuration could be, for example, the absolute and / or relative interconnection of heating units which, in at least one operating state, heat cooking batteries arranged in adjacently and / or the coupling sequence of heating units that, in at least one operating state, heat cooking batteries arranged adjacently. The heating zone setting could correspond to a cooking battery configuration. Of 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 heat the heating zones and / or the cooking batteries optimally, so that optimum cooking results and / or a high degree of user satisfaction can be achieved.

In at least one operating state, the control unit could, for example, assign at least two heating frequency units to a single heating unit and operate the heating unit in the operating state in an enhancer mode and / or With a higher heating power. Preferably, at any time in the operating state, the control unit avoids the assignment of two heating frequency units to a heating unit. In at least one operating state, the control unit assigns a maximum of one heating frequency unit simultaneously to at least one single heating unit. In at least one operating state, the control unit could assign 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 duration of period. Thus, overloading of the heating units can be avoided, and a lasting embodiment can be achieved in this way.

Particularly advantageously, at any time in the operating state, the control unit avoids the assignment of one of the heating frequency units to at least two heating zones that are intended to heat at least two different cooking batteries, of so that the generation of intermodulation hums can be avoided.

In at least one operating state, the control unit could, for example, exclusively assign a single heating frequency unit to a single heating zone in a common advantageous manner. Preferably, the control unit assigns in the operating state at least two of the heating frequency units to a single heating zone in a common advantageous manner. In at least one operating state, the control unit assigns one of the heating frequency units and, advantageously, each of the heating frequency units, to a maximum heating zone, so that the quantity of heatable cooking batteries maximum and / or the maximum possible number of heating zones corresponds to the number of frequency units of heating. Thus, it is possible to optimally heat even large heating zones and / or large cooking batteries and / or raise their temperature in an acceptable time, so that a short cooking time and / or optimal cooking results can be achieved and / or a high degree of user satisfaction.

In a heating zone configuration in which at least three heating zones are arranged, each of which could be assigned to a cooking battery supported on at least one of the cooking surface sections, the control unit could issue information through at least one user interface in at least one operating state. The information could be, for example, a command requirement for at least one of the cooking batteries to be supported on another of the cooking surface sections. Alternatively or additionally, the information could present at least one warning that a maximum of two cooking batteries are heated in one of the partial cooking surface areas and / or that a maximum of three cooking batteries are heated in one of partial cooking surface areas.

In at least one operating state, the first partial cooking surface area and the second partial cooking surface area could be arranged adjacent to each other in at least the transverse direction. Preferably, in at least one operating state, the first cooking surface section and the second cooking surface section are arranged adjacent to each other in at least the depth direction. The term "depth direction" includes the concept of a direction which, when observed perpendicularly on the variable area of cooking surface and / or on the main extension plane of the support plate in at least one operating state, from the area directed towards the user towards the area opposite to the user, is oriented approximately or exactly perpendicular to at least one edge of the cooking field directed towards the user and / or at least one defining edge of the variable area of directed cooking surface towards the user. The expression "roughly or exactly perpendicularly" includes the concept of the orientation of a direction relative to a reference direction in a plane, where, observed in a plane, the direction and the reference direction enclose an angle 90 ° and the angle has a maximum deviation of 8 ° maximum, advantageously, 5 ° maximum and, in particular ularly advantageous, maximum 2 °. The term "transverse direction" includes the concept of a direction which, when observed perpendicularly on the variable area of the cooking surface and / or on the main extension plane of the support plate in at least one operating state, is oriented approximately or exactly parallel to at least one edge of the cooking field directed towards the user and / or at least one delimiting edge of the variable area of cooking surface directed towards the user, and which is oriented perpendicularly to the direction of depth when observed perpendicularly on the variable cooking surface area and / or on the main extension plane of the support plate in at least one operating state. In this way, simple and / or equal accessibility to the partial cooking surface areas is made possible, thereby making it possible for the user to work flexibly.

In addition, it is proposed that the heating units defining the first cooking surface section and the heating units defining the second cooking surface section be connected to exactly one phase of the voltage of the single grid current and / or common in at least one operating state. In this way, a simple embodiment can be achieved and / or it is unlikely that intermodulation buzzes will occur.

Likewise, heating of the cooking batteries and / or of the heating zones particularly optimized can be achieved by means of a cooking field, in particular, by an induction cooking field, with at least one cooking field device according to the invention.

The heating of the cooking batteries and / or of the heating zones can be further improved by a procedure for the operation of a cooking field device with multiple heating units defining at least one variable surface area of cooking and which are carried out as induction heating units, with at least a first heating frequency unit that is assigned exclusively to first heating units of the heating units, which define a first defined cooking surface section of fixed way of the variable cooking surface area, and with at least a second heating frequency unit that is assigned exclusively to second heating units of the heating units, which define a second cooking surface section of the variable cooking area of cooking surface, fixedly defined and other than the first cooking surface section, and with at least a third heating frequency unit, where the third heating frequency unit is optionally assigned to at least a part of the first heating units and / or at least a part of the second heating units in at least one operating state.

The first partial cooking surface area 16a and the second partial cooking surface area 18a are made essentially identical, so that only the first partial cooking surface area 16a is described below.

The cooking field device 10a has a first heating frequency unit 28a (see Figure 2). The first heating frequency unit 28a is assigned exclusively to the first heating units 12a1 of the heating units 12a that define the first cooking surface section 20a of the variable cooking surface area 14a.

In addition, the cooking field device 10a has a connection unit 52a. The connection unit 52a is intended to establish and / or separate an electrically conductive connection between the heating frequency units 28a, 30a, 32a and the heating units 12a. The connection unit 52a is electrically arranged between the heating units 12a and the heating frequency units 28a, 30a, 32a. In an operating state, the connection unit 52a is intended to be activated by the control unit 36a.

In an operating state, the third heating frequency unit 32a is assignable to a percentage of 100% of the first heating units 12a1 and a percentage of 100% of the second heating units 12a2.

In this exemplary embodiment, two first heating units 12a1 arranged adjacent to each other are optionally assignable in each case simultaneously to the first heating frequency unit 28a and / or the third heating frequency unit 32a. As an example, in an operating state, two first heating units 12a1 arranged adjacent to each other could be assigned simultaneously to the first heating frequency unit 28a. In an operating state, one of the first two heating units 12a1 arranged adjacent to each other could be assigned, for example, to the first heating frequency unit 28a, and another of the first two heating units 12a1 arranged adjacent to each other could be assigned, for example, to the third heating frequency unit 32a. As an example, in an operating state, two first heating units 12a1 arranged adjacent to each other could be simultaneously assigned to the third heating frequency unit 32a.

In this exemplary embodiment, two second heating units 12a2 arranged adjacent to each other are optionally assignable in each case optionally to the second heating frequency unit 30a and / or the third heating frequency unit 32a. As an example, in an operating state, two second heating units 12a2 arranged adjacent to each other could be assigned simultaneously to the second heating frequency unit 30a. In an operating state, one of the two second heating units 12a2 arranged adjacent to each other could be assigned, for example, to the second heating frequency unit 30a, and another of the second second heating units 12a2 arranged in adjacent to each other could be assigned, for example, to the third heating frequency unit 32a.

In an operating state, the control unit 36a assigns the third heating frequency unit 32a to the part of the first heating units 12a1 or to the part of the second heating units 12a2 depending on the heating zone configuration. For the assignment of the heating frequency units 28a, 30a, 32a to the corresponding heating units 12a, the control unit 36a activates in a functioning state the connection unit 52a and / or the activation connection unit 54a.

In the case of a heating zone configuration in which three small cooking batteries 60a are arranged in the first partial cooking surface area 16a, the control unit 36a forms a heating zone from an operating state from the heating units 12a for each cooking battery 60a supported (see Figure 3). In the case of a heating zone configuration in which three small cooking batteries 60a are arranged in the first partial cooking surface area 16a, the control unit 36a assigns in one operating state one of the frequency units of heating 28a, 30a, 32a in a common way to the heating units 12a forming a heating zone.

In the case of a heating zone configuration in which a small cooking battery 60a and a large cooking battery 60a are arranged in the first partial cooking surface area 16a, the control unit 36a forms in an operating state a heating zone from heating units 12a for each cooking battery 60a supported (see figure 5). In the case of a heating zone configuration in which a small cooking battery 60a and a large cooking battery 60a are arranged in the first partial cooking surface area 16a, the control unit 36a assigns in an operating state one of the heating frequency units 28a, 30a, 32a common to the heating units 12a that form the heating zone that heats the small cooking battery 60a, and two of the heating frequency units 28a, 30a, 32a common to the heating units 12a that form the heating zone that heats the large cooking battery 60a. In an operating state, the control unit 36a assigns two of the heating frequency units 28a, 30a, 32a to a single heating zone.

In the case of a heating zone configuration in which a very large cooking battery 60a is disposed in the first partial cooking surface area 16a, the control unit 36a forms a heating zone from an operating state from of the heating units 12a for the supported cooking battery 60a (see Figure 4). In the case of a heating zone configuration in which a very large cooking battery 60a is arranged in the first partial cooking surface area 16a, the control unit 36a assigns three of the frequency units in an operating state of heating 28a, 30a, 32a in a common way to the heating units 12a that form the heating zone that heats the very large cooking battery 60a and, thereby, all the heating frequency units 28a, 30a, 32a available for the heating units 12a that define the first partial cooking surface area 16a. In an operating state, the control unit 36a assigns three of the heating frequency units 28a, 30a, 32a to a single heating zone.

At any time in the operating state, the control unit 36a prevents the assignment of two heating frequency units 28a, 30a, 32a to a single heating unit 12a by corresponding activation of the connection unit 52a and / or the activation connection unit 54a. In an operating state, the control unit 36a assigns a maximum of one of the heating frequency units 28a, 30a, 32a to each heating unit 12a.

In a procedure for commissioning the cooking field device 10a, the third heating frequency unit 32a is assigned in a state of operation optionally to the part of the first heating units 12a1 and / or to the part of the second heating units 12a2.
