Abstract

Die Erfindung geht aus von einer Gargerätevorrichtung mit zumindest zwei Heizfrequenzeinheiten (10, 12) und mit wenigstens einer Steuereinheit (14), die dazu vorgesehen ist, eine jeweilige mittlere Ausgangsleistung (P0A, P0B) der Heizfrequenzeinheiten (10, 12) unter weitgehender Vermeidung von Intermodulationsgeräuschen einzustellen.The invention is based on a cooking device device with at least two heating frequency units (10, 12) and with at least one control unit (14) which is intended to substantially lower a respective average output power (P 0A , P 0B ) of the heating frequency units (10, 12) Avoiding intermodulation noise.

Um eine gattungsgemäße Gargerätevorrichtung mit einer möglichst kontinuierlichen Leistungsabgabe bereitzustellen, wird vorgeschlagen, dass die Steuereinheit (14) dazu vorgesehen ist, eine von null verschiedene Frequenz (f2) einer der Heizfrequenzeinheiten (12) unter Beibehaltung eines Betriebs der anderen Heizfrequenzeinheit (10) auf einen von null verschiedenen Wert (f3) zu verändern.

Figure imgaf001
To provide a generic Gargerätevorrichtung with a continuous power output, it is proposed that the control unit (14) is provided to a non-zero frequency (f 2 ) of the Heizfrequenzeinheiten (12) while maintaining an operation of the other Heizfrequenzeinheit (10) to change a value other than zero (f 3 ).
