PROBLEM TO BE SOLVED: To construct a high frequency heating apparatus with high reliability capable of heating a food to a proper temperature irrespective of any differences of initial temperatures of a food, differences of food materials, and the presence of lapping. SOLUTION: In a high frequency heating apparatus comprising a heating chamber 2 for accommodating a food 1, a weight sensor 5 for detecting the weight of the food 1, an infrared sensor 6 for detecting temperature information, a vapor sensor 7 for detecting the amount of vapor, and a microcomputer 8 for executing heating control, reference heating time t is set on the basis of the temperature of the food 1 detected by the infrared sensor 6 after the passage through predetermined time ts since the starting of heating and the weight of the food 1 detected by the weight sensor 5. Further, the reference heating time t is divided into a plurality of heating intervals of a first heating time ts1, next heating interval ts2, and heating interval ts3 up to the reference heating time t. The food 1 is finished to a proper temperature based upon temperature data detected by the infrared sensor 6 in the heating interval ts1 and the heating interval ts3, and based upon temperature data detected by the infrared sensor 6 and the data of the amount of vapor detected by the vapor sensor 7 in the heating interval ts2. |
