Abstract

L'invention concerne un dispositif d'appareil électroménager, notamment un dispositif d'appareil de cuisson, comprenant au moins un module de puissance (18), au moins deux unités consommatrices (20, 22, 24, 26) et au moins une unité de commande (34). L'objectif de l'invention est d'obtenir une amélioration de confort. A cet effet, dans au moins un mode de fonctionnement dans lequel au moins deux des unités consommatrices (20, 22, 24, 26) sont alimentées de manière commune par le module de puissance (18) et dans lequel une somme de puissances requises pour les unités consommatrices (20, 22, 24, 26) dépasse une puissance disponible du module de puissance (18), l'unité de commande (34) est conçue pour répartir au moins une partie de la puissance disponible entre les unités consommatrices (20, 22, 24, 26) en fonction d'au moins une grandeur caractéristique de fonctionnement.
