でない。When the mode is shifted to the automatic discrimination mode as described above, or when cooking is performed in the automatic discrimination mode from the beginning, normal control is performed, and the following processing is carried out to prepare a water-based dish or an oil-based dish. The determination processing unit 63 determines whether it is a dish and sets the set temperature for forcibly extinguishing the fire to T 0 ° C or T 1 ° C. That is, in the present embodiment, when the temperature detected by the temperature sensor 5 rises and reaches a temperature slightly lower than the boiling point of water, the determination processing unit 63 sets the time from when the temperature reaches the temperature until the detected temperature passes through the certain temperature range. When the counted time is multiplied by a constant coefficient as a reference time, the time when the detected temperature rises to a certain temperature from the time when the detected temperature substantially reaches the boiling point of water is counted, and when the count value becomes longer than the reference time It is assumed that the boiling point is detected, and if the boiling point is detected, it is determined that the dish is a seafood dish. If the count value is shorter than the reference time, it is determined that the dish is an oil-based dish. That is , the determination processing unit 63 has a dish determination function. Based on these determinations, the determination processing unit 63 sets the set temperature for forcibly extinguishing the burner 1 to T 0 ° C or T 1 ° C. In the case of the above-mentioned boiling point detection, when the detected temperature drops, the process waits until the temperature rises again, and the temperature rise due to the raising of the pot is not counted, but is counted again from the time when the temperature drops. However, the detection operation is reset after a certain period of time even if the temperature rise is continued from the time when it is determined that the pot is raised. Of course, it may be possible to determine whether the dish is a water dish or an oil dish by a method other than the above-mentioned boiling point detection, and the method is not particularly limited to the method adopted in the above embodiment.

いう効果がある。According to the present invention, there is provided an automatic cooking mode in which a dish is determined to be a water dish or an oil dish based on the temperature detected by the temperature detecting section in the heating cooking apparatus constructed as described above, and the dish is made of porcelain. In addition to a mode switching unit that switches and sets a pottery mode set in a certain case, the determination processing unit determines whether the dish is a water dish based on the temperature detected by the temperature detection unit in the automatic determination mode. If the food discrimination function is a seafood dish, the set temperature (T 0 ° C) corresponding to the scorching temperature in the seafood dish is compared with the temperature detected by the temperature detector, and the discrimination result must be a seafood dish. Ba
The set temperature (T 1 ° C ) corresponding to the oil ignition temperature when using oil and the detected temperature of the temperature detector are compared. In the pottery mode, the upper limit set temperature (T 2 ° C) corresponding to the pottery dish and the temperature detector
If the detected temperature is higher than the set temperature by comparing the detected temperature, a normal control function that outputs a control signal for heating stop, and a heating start time point under the automatic determination mode switched from the pottery mode by the mode switching unit. The temperature detected by the temperature detector at the temperature is the set temperature corresponding to the oil ignition temperature when oil is used.
Even (T 1 ° C.) or does not output the control signal for a fixed time heating stopped, the own when the temperature detected by the temperature detecting portion at this predetermined time lapse has been lowered from the detected temperature of the heating start time <br The operation is shifted to the operation in the motion determination mode, and the temperature detected by the temperature detection unit at the time when a certain time has elapsed is lower than the temperature detected at the time when the heating is started.
The heating control means has a heating start control function that outputs a control signal to stop heating when it is not lowered, so the set temperature for stopping the heating operation of the heating means in the automatic determination mode or the pottery mode is suitable for each. Temperature can be set to prevent burning, ignition, etc. in each of them, it is excellent in safety, and when cooking in the automatic determination mode continuously after grilled dishes In addition, the temperature detected by the temperature detector at the time when the above set temperature is switched from the set temperature in the pottery mode to the set temperature in the automatic determination mode is different from the oil ignition temperature when oil is used in the automatic determination mode.
Even if the temperature is equal to or higher than the applicable set temperature (T 1 ° C) , the temperature is detected after a certain period of time by checking the change in the temperature detected by the temperature detector.
The temperature detected by the detector is lower than the temperature detected at the start of heating.
In the case of dropping, the heating operation can be continued, so that there is an effect that cooking is not interrupted and the usability can be improved.
