  • the present invention relates to a so-called automatic high-frequency heating device that cooks food by high-frequency heating, detects the cooking state of the food, and automatically determines the heating time.
  • the heating time of food at high frequency is determined by various factors such as the initial temperature, lO amount, final temperature, specific heat and high frequency energy-absorption rate of the food to be heated.
  • the user has set the time determined by the item and quantity of the food to be heated by a timer. Therefore, the initial temperature of the food is not taken into account, so cooking mistakes are likely to occur. If the amount changes, the heating time must be calculated and set every time.

Abstract

Un oeuf est chauffé à faible puissance jusqu'à atteindre de 70 à 95oC de la température de cuisson de l'oeuf, et le signal émis par un détecteur (8) détectant de faibles quantités de vapeur, gaz ou odeurs produits par l'oeuf chauffé pendant le fonctionnement à faible puissance sert à régler et à commander le temps de chauffage à pleine puissance, permettant ainsi d'obtenir la cuisson automatique de l'oeuf par micro-ondes.
