Abstract

Die Erfindung geht aus von einer Gargerätevorrichtung mit zumindest einer ersten und zumindest einer zweiten Heizfrequenzeinheit (10, 12) und mit wenigstens einer Steuereinheit (14), die dazu vorgesehen ist, eine jeweilige mittlere Ausgangsleistung (Pave1, Pave2) der zumindest zwei Heizfrequenzeinheiten (10, 12) unter Minimierung einer Flickerkenngröße (F) einzustellen und die zumindest zwei Heizfrequenzeinheiten (10, 12) in wenigstens einem ersten Zeitintervall (TA) mit einem ersten Satz von Frequenzen (f1A, f2A) und in wenigstens einem zweiten Zeitintervall (TB) mit einem zweiten, vom ersten Satz unterschiedlich ausgebildeten Satz von Frequenzen (f1B, f2B) zu betreiben.The invention is based on a cooking device device with at least one first and at least one second heating frequency unit (10, 12) and with at least one control unit (14) which is provided with a respective average output power (P ave1 , P ave2 ) of the at least two heating frequency units (10, 12) while minimizing a flicker characteristic (F) and the at least two heating frequency units (10, 12) in at least a first time interval (T A ) with a first set of frequencies (f 1A , f 2A ) and in at least one second Time interval (T B ) with a second, different from the first set trained set of frequencies (f 1B , f 2B ) to operate.

Um eine gattungsgemäße Gargerätevorrichtung bereitzustellen, die eine vorteilhaft flexible Einstellung einer mittleren Ausgangsleistung ermöglicht, wird vorgeschlagen, dass sich die Frequenzen (f1A, f2A) des ersten Satzes von Frequenzen (f1A, f2A) untereinander um mindestens 14 kHz unterscheiden und sich die Frequenzen (f1B, f2B) des zweiten Satzes von Frequenzen (f1B, f2B) untereinander um mindestens 14 kHz unterscheiden.

Figure imgaf001
In order to provide a generic cooking device that allows advantageously flexible adjustment of average output power, it is proposed that the frequencies (f 1A , f 2A ) of the first set of frequencies (f 1A , f 2A ) differ from one another by at least 14 kHz and the frequencies (f 1B , f 2B ) of the second set of frequencies (f 1B , f 2B ) differ from one another by at least 14 kHz.
