面温度が上昇し過ぎるためである。Recently, with the development of microcomputers, it has become possible to easily implement complex control at low cost. The present invention also makes full use of this microcomputer to propose a more efficient heat retention method. Recent cooking utensils use various sensors and control means to automatically start cooking after the start of cooking. It is difficult to predict the end time of cooking as the cooking progresses and ends automatically, and the need to keep food warm after heating is increasing. However, it is extremely difficult to maintain a constant internal temperature of food using a heater. This is because it takes a long time to react, which slows down the reaction rate and causes the surface temperature of the food to rise too much.

づき説明する。The present invention takes advantage of the features of high-frequency heating and switches to high-frequency heating to keep the food warm after the heater heating ends, so the temperature sensing means inserted into the food reacts quickly, keeps the food stable, and keeps it warm for a long time. For example, it is very effective because it reduces the temperature of the heating chamber, eliminating the risk of burns. Embodiments of the present invention will be described below based on the drawings.

。Here, a case will be described using FIG. 3, taking as an example a case where the temperature inside the refrigerator is controlled by the heater 15 and then kept warm by high frequency. The control unit 1 sets the temperature of the heating chamber 5, the cooking end temperature of the food, and the heat retention time and starts the operation. The control circuit 12 closes the power relay 8, and the bidirectional control rectifier 1
6 becomes conductive, a voltage is applied to the heater 15, and heating begins. This is the slope portion of the heating chamber temperature at A roll call shown in FIG. When the temperature of the heating chamber reaches the set temperature, the bidirectional control rectifier 16 starts to be switched on and off by the detection element that detects the temperature inside the chamber to keep the temperature inside the chamber constant. This is the period from point A to point B' shown in the figure. On the other hand, the temperature of the food is detected by the temperature probe 2 and gradually rises due to the circulating hot air, and when it reaches the set temperature,
The bidirectional control rectifier turns off and heater heating ends.

After that, the temperature rises due to residual heat in the heating chamber 5, and from the 0 point where the food temperature decreases and becomes lower than the set temperature, the reed switch is turned on. Intermittent operation of 18 is started, and heat retention by high frequency begins.0 As described above, in the present invention, by switching from heater heating to heat retention by high frequency heating, it is possible to perform continuous temperature control with the same temperature probe.
