    The invention relates to a cooking field device (10a-b) with a receiving unit (12a-b) which is provided to receive at least one informative data, and with a control unit (14a-b) which is provided for for activating in at least one operating state at least one power supply unit (16a-b) and for accessing the receiving unit (12a-b). In order to provide a generic cooking field device with advantageous operation properties, it is proposed that the control unit (14a-b) is provided to deactivate the power supply unit (16a-b) in the operating state. During an idle time interval (18a-b) and for accessing the receiving unit (12a-b) in the idle time interval (18a-b). (Machine-translation by Google Translate, not legally binding)

    brief inactivity and, in addition to this, a large amount of energy can be provided to a heating unit to heat the cooking battery resting on it.
    Likewise, it is proposed that the control unit be provided to operate the power supply unit with a connection frequency, the value of which varies continuously, in the operating state in a first time interval, which is directly followed in the time the idle time interval. Specifically, the control unit is intended to change the frequency value of the high frequency supply current, supplied by the power supply unit, constantly in the operating state. Also, the control unit is intended to activate in the operating state at least one inverter of the power supply unit, in particular at least one connection element of at least one inverter of the power supply unit, and to modify the value of the connection frequency continuously. Specifically, the control unit is intended to modify in the operating state the envelope curve of the electric supply current, which flows through at least one heating unit, through the continuous modification of the value of the frequency of Connection. In this way, great efficiency can be achieved and / or that a flexible influence is exerted on the electric supply current flowing through at least one heating unit. The enveloping curve of an electric supply current flowing through at least one heating unit can be quickly reduced to zero, thereby preventing noise from being produced as a result of an inconstant modification of the electrical supply current. . Likewise, fluctuations can be avoided and / or the frequency of fluctuations can be reduced. It can also be achieved that there is little loss in the power supply unit and / or an embodiment that saves energy.
    In addition, it is proposed that the control unit be provided to operate the power supply unit with a connection frequency, the value of which varies continuously, in the operating state in a second time interval, which follows directly in the time to idle time interval. In this way, high efficiency and / or flexible influence on the electric power supply current flowing through at least one heating unit can be achieved. The enveloping curve of an electric supply current flowing through at least one heating unit can be rapidly increased from scratch, thereby preventing noise from being produced as a result of an inconstant modification of the electrical supply current. . It can also be avoided

    the occurrence of fluctuations and / or reduce the frequency of the appearance of fluctuations. It can also be achieved that there is little loss in the power supply unit and / or an embodiment that saves energy.
    Likewise, it is proposed that the control unit be provided to provide in the operating state the idle time interval approximately or exactly symmetrically with respect to a zero crossing of a supply voltage, in particular, a voltage of net. The supply voltage is an alternating voltage. As an example, the supply voltage could have a frequency with a value of approximately 50 Hz. The duration of the period of the supply voltage could have a value of approximately or exactly 20 ms. Alternatively, the supply voltage could have a frequency with a value of approximately 60 Hz, where the duration of the period of the supply voltage could have a value of approximately or exactly 16.7 ms. The deviation from the central point of the idle time interval with respect to the zero crossing of the supply voltage amounts to a maximum of 1 ms, preferably, a maximum of 0.7 ms, advantageously, a maximum of 0.3 ms and, particularly advantageously, at 0.1 ms maximum, as well as 15% maximum, preferably, 10% maximum, advantageously, 5% maximum, particularly advantageously, 3% as maximum and, preferably, 1% maximum of the total duration of the idle time interval. In this way, an efficient and / or energy saving realization can be achieved.
    In addition, it is proposed that the control unit be provided to provide in the operating state the idle time interval approximately or exactly asymmetrically with respect to a zero crossing of a supply voltage. The deviation from the central point of the idle time interval with respect to the zero crossing of the supply voltage is greater than 1 ms, preferably, greater than 0.7 ms, advantageously, greater than 0.3 ms and, of particularly advantageous, greater than 0.1 ms, and is greater than 15%, preferably, greater than 10%, advantageously, greater than 5%, particularly advantageous, greater than 3% and, preferably, superior at 1% of the total duration of the idle time interval. Thus, great flexibility can be achieved.
    Particularly advantageous operating properties 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, in particular, with at least one cooking field device. by induction according to the invention.
