Abstract:
1. A control method of a high-frequency heating apparatus with steam generation function for supplying a high frequency and steam to a heating chamber for storing a heated material and heat-treating the heated material, comprising the steps of: heat-treating the heated material by performing high-frequency heating treatment for heat-treating with a high frequency and steam heating treatment for heat-treating with steam generated in the heating chamber in order separately or at the same time for heat-treating the heated material; agitating air in the heating chamber to circulate the air in the heating chamber when the heat-treating is performed; measuring the temperature in the heating chamber by a temperature detection sensor; storing the temperature measurement result in a storage section; comparing frozen food determination temperature preset in the storage section with the temperature measurement result; and selecting a heating program, wherein a heating program for performing high-frequency heating treatment and then switching to steam heating treatment for heating the heated material is selected when the temperature measurement result is higher than the frozen food determination temperature, and a heating program for performing high-frequency heating treatment and steam heating treatment at the same time and then stopping only the high-frequency heating treatment to execute the steam heating treatment to heat the heated material when the temperature measurement result is equal to or less than the frozen food determination temperature, wherein said step of heat-treating the heated material is performing based on the selected heating program.
