    to transform the current supply modules into the main current supply module and the secondary current supply module. The term "control unit" includes the concept of an electronic unit that is preferably integrated, at least in part, into a control and / or regulator unit of a cooking appliance, and which is preferably provided for directing and / or regulate at least the allocation unit and / or at least the power supply modules.
    Preferably, the control unit comprises a calculation unit and, in addition to the calculation unit, a storage unit with a control and / or regulation program stored therein, which is intended to be executed by the unit of calculation. The expression that the control unit is intended to "activate" in at least one state of heating operation the power supply modules to generate a high frequency heating current includes the concept that, by means of the transmission of In a control signal to the connection elements, the control unit modifies the connection position of the connection elements of the connection units periodically with a heating frequency having a value between 10 kHz in the heating operating state and 150 kHz, preferably between 20 kHz and 100 kHz, and with which the high frequency heating current flows through the heating element in the heating operating state. The term "main power supply module" includes the concept of a power supply module that in at least one operating state and, in particular, at least in the heating operating state, is intended for independent operation, in particular, for independent operation of other power supply modules. In at least one operating state and, in particular, at least in the heating operating state, a mains voltage configured as an alternating voltage is applied to the main current supply module, which is supplied by an electrical network of a cooking appliance At least in the heating operating state, the main power supply module could be provided, for example, for solo operation, and could be activated while the remaining power supply modules are deactivated.
    Alternatively, the main power supply module could be provided at least in the heating operating state for its joint operation with at least one other power supply module, in particular, with at least one other main power supply module and / or with at least one secondary power supply module.

    30
    35
    other current supply modules, in particular, of the voltage supplied by at least one other current supply module, thanks to the mains voltage applied to the main current supply module. The term "secondary current supply module" includes the concept of a current supply module that in at least one operating state and, in particular, at least in the heating operating state, is intended for commissioning. only in dependence on at least one main power supply module In at least one operating state and, in particular, at least in the heating operating state, an influenced voltage is applied to the secondary current supply module less partially by the main power supply module, which could be rectified at least partially and / or increased at least partially and / or reduced at least partially and / or at least partially invested by the main power supply module. Secondary current supply module is operable at least in the operating state of heating for at least u n main current supply module, in particular, by the main current supply module, as a consequence of the voltage at least partially influenced by the main current supply module and applied to the secondary current supply module, in a dependent manner of and exclusively together with the main power supply module. By way of example, the secondary current supply module could be dependent on a single main current supply module at least in the heating operating state. Alternatively or additionally, the secondary current supply module could be dependent on at least two main current supply modules at least in the heating operating state. To the secondary current supply module, a voltage influenced at least partially by at least two main current supply modules could be applied at least in the heating operating state. The control unit is intended to redefine in each heating operating state at least one main current supply module and at least one secondary current supply module. Specifically, the control unit is intended to define in a first heating operating state at least a first main current supply module and at least a first secondary current supply module, and to define in a second operating state of heating, different with respect to the first operating state of heating, at least a second main power supply module, different with respect to the first main power supply module of

    35
    current, and at least a second secondary current supply module, different from the first secondary current supply module. Thus, the control unit is intended to redefine at least one main current supply module and at least one secondary current supply module on a case-by-case basis. The term "intended" includes the concept of programmed, conceived and / or provided specifically. The expression that an object is intended for a specific function includes the concept that the object satisfies and / or performs this function determined in one or more application and / or operating states.
    Through realization according to the invention, great flexibility can be achieved, in particular, in relation to the necessary energy and / or loss due to switching. Likewise, it is possible to create multiple possible configurations in which the power supply modules could be defined relative to each other, so that optimum manageability and / or optimum controllability and / or great versatility can be achieved. In the event that there are multiple power supply modules and multiple heating elements, it is possible to dispense with a connection of each power supply module with each of the other power supply modules and / or with each of the other heating elements, whereby it is possible to achieve low costs and / or high savings potential, which will be greater the greater the amount of current supply modules and heating elements. In different heating operating states, it is possible to define different current supply modules as the main current supply module, thereby making it possible to have great flexibility and / or a uniform thermal distribution, in particular, a uniform thermal load, of power supply modules.
    In addition, it is proposed that the allocation unit present a connection matrix. The term "connection matrix" includes the concept of a unit that is defined by a composition of several connection elements. The assignment unit has several connection elements that define the connection matrix and which are arranged in a matrix form relative to each other. In this way, particularly high flexibility can be achieved with simple means.
    Likewise, it is proposed that the assignment unit have at least two connection elements connected side by side. The expression connection elements "connected side by side" includes the concept of connection elements of the same hierarchy and / or the same category. The electric current that flows through
    5
    10

    twenty
    25
    30
    35
    The allocation unit is divided between the closed connection elements depending on at least two closed connection elements connected side by side of the allocation unit. The first part of the electric current flowing through the allocation unit flows through the first of the closed connection elements connected side by side, and the second part of the electric current flowing through the unit assignment flows through the second of the closed connection elements connected side by side, different from the first of the closed connection elements connected side by side. In this way, a particularly flexible allocation unit can be provided.
    By way of example, the assignment unit could only present connection elements arranged next to each other and be composed exclusively of connection elements connected next to each other. In the event that the allocation unit exclusively has connection elements arranged next to each other, each of the current supply modules can be defined as the main current supply module. Preferably, the allocation unit has at least two connection elements connected one behind the other in addition to the connection elements connected side by side. The expression connection elements "connected one behind the other" includes the concept of connection elements of a different hierarchy and / or of a different category, which are connected one behind the other and / or in series. At least one input of the first of the connection elements connected one behind the other is connected to an output of at least the second of the connection elements connected one behind the other, different from the first of the connection elements connected one behind of other. Thus, a single current supply module and, advantageously, any current supply module can be defined specifically as the main current supply module.
    Likewise, it is proposed that the control unit be provided to deactivate, in particular, all current supply modules by means of the allocation unit in at least one assignment configuration. In particular, the control unit is not provided in the assignment configuration to define neither a main current supply module nor a secondary current supply module, and is intended to separate the, in particular, all the power supply modules. current from a source of energy, in particular, from a source of voltage, in particular, from a network voltage. In the assignment configuration, to none of the
    5
    10
    fifteen
    twenty
    25
    30
    35
    Power supply modules voltage is applied. Thus, it is possible to dispense with a main connection element that could be provided to deactivate the power supply modules and / or to separate them from a mains voltage, so that the costs can be low.
    In addition, it is proposed that the cooking appliance device has at least one voltage transformer element, which is connected to the main power supply module through the allocation unit in the heating operating state. In the operating state of heating, an electric current, in particular a heating current, flows first through the voltage transformer element, then through the assignment unit and then through the power module. main power supply.
    An electric current, in particular, a heating current, which flows in the heating operating state from the voltage transformer element to the main current supply module, necessarily flows through the allocation unit. The term "voltage transformer element" includes the concept of an element of a voltage actuation stage. The term "voltage actuation stage" includes the concept of a unit that is provided in at least one operating state and, in particular, at least in the heating operating state, to transform the voltage applied to an input of the unit into a voltage with a modified value of the voltage, and to emit the modified voltage at an output of the unit. The voltage actuation stage could be provided to transform the voltage applied at the input into a voltage with a lower and / or higher value and / or inverted in the heating operating state. The voltage actuation stage could be an elevator drive stage and / or a reducer drive stage and / or a reducer-lift drive stage and / or a synchronous drive stage. In this way, the voltage applied to the main power supply module in the heating operating state can be optimally adapted and / or modified.
    The voltage transforming element could be realized, for example, as a capacity, in particular as at least one capacitor, and / or as a diode and / or as a connection element and / or as a resistive electrical component. However, the voltage transformer element is preferably made as an inductor. In particular, the voltage transformer element is made as an inductor made differently with respect to a heating inductor, in particular, a heating element. In this way, the tension applied to the
    5

    25
    30
    35
    Main power supply module in the heating operating state can be optimally adapted and / or modified.
    Likewise, it is proposed that the cooking appliance device has a lifting drive stage, which has the voltage transformer element and the main current supply module. The voltage transformer element is particularly advantageously realized as an enhancer inducer. The lifting drive stage is intended to transform an input voltage into an output voltage that is higher than the input voltage. The term "lifting drive stage" includes the concept of a voltage driving stage that is intended to transform a first voltage, namely, the input voltage, into a second voltage, specifically, the output voltage. The lifting actuator stage presents the voltage transformer element realized as an inductor, in particular as an enhancer inductor, a diode connected in series with the voltage transformer element, a connection element, and a capacity, in particular, a capacity of storage, which is arranged at one end, opposite the voltage transformer element, of the series connection of the voltage transformer element and the diode.The control unit is intended to apply the input voltage to the transformer element of the voltage tension by modifying the connection position of the connection element of the lifting drive stage, and to connect the capacity and the voltage transformer element parallel to each other. The voltage transformer element is intended to increase the energy stored in the voltage transformer element in the event that a connection element of the lifting drive stage is closed, in particular, with an input voltage being applied. Also, in the event that a connection element of the lifting drive stage is open, in particular, without an input voltage being applied, the voltage transformer element is provided to maintain without modifying the current flow that it flows through it and, thereby, charge through the diode of the lifting drive stage the capacity of the lifting drive stage, which stores the electric energy transmitted by the voltage transformer element. The diode of the lifting drive stage is intended to largely or completely prevent the reflux of the energy stored in the capacity of the lifting drive stage in the direction of the voltage transforming element. The connecting element of the lifting drive stage and the diode of the lifting driving stage may be periodically alternately formed by an element of

    connection of a first connection unit of the main power supply module and by a diode of a second connection unit of the main power supply module, on the one hand and, on the other hand, by a connection element of the second unit of connection of the main power supply module and by a diode of the first connection unit of the main power supply module. In this way, high efficiency can be achieved, since, advantageously, a lower electric current is necessary to achieve a given output power.
    In addition, it is proposed that the cooking appliance device has a first and a second rectifier diode, which are intended to assist in the rectification of the alternating voltage in the heating operating state. Thus, great reliability is possible by rectifying the alternating voltage. In addition, an economic realization can be achieved.
    As an example, the cooking appliance device could have a third and fourth rectifier diode, which could be provided to assist in the rectification of the alternating voltage in the heating operating state. Preferably, the main current supply module is provided to assist in the rectification of the alternating voltage in the heating operating state. In this way, great efficiency can be achieved, being able to feed several heating elements with a small amount of electrical and / or electronic construction units. Advantageously, it is possible to feed any combination of heating elements. In addition, it can be achieved that the conduction losses are small and, thus, make high efficiency possible. Likewise, great flexibility can be achieved, as the conductivity for the electric current of the main current supply module can be modified in the desired way to rectify the alternating voltage, where rectification can be advantageously made possible through the diodes and / or through the connection elements of the connection units of the main power supply module.
    Particularly high flexibility can be achieved through a cooking device, in particular, through a cooking field and, advantageously, through an induction cooking field, with at least one cooking device device according to the invention, in particular with at least one cooking field device according to the invention and, advantageously, with at least one induction cooking device according to the invention.

    It is possible to increase the flexibility to a greater extent by means of a method for putting into operation a cooking appliance device according to the invention, in particular, a cooking field device according to the invention and, advantageously, with a cooking device. induction cooking field according to the invention, with at least two current supply modules, which are activated in at least one heating operating state to generate a high frequency heating current for at least one heating element of the device of cooking apparatus and, in the operating state of heating, at least one of the current supply modules is defined as the main module of independently operable current supply and at least one of the current supply modules is defined as a secondary power supply module that can only be operated in interaction with the supply module main istro of current. In each heating operation state, at least one main current supply module and at least one secondary current supply module are redefined. The definition of at least one main current supply module and at least one secondary current supply module is carried out in the heating operating state and, specifically, temporarily after assembly, is independent of the geometric arrangement of the power supply modules relative to each other through an arrangement fixed in a non-modifiable manner during assembly, and is independent of a physical current connection. At least one main current supply module and at least one secondary current supply module are defined again on a case-by-case basis.
