However, in the temperature control device configuration of the conventional heating cooker shown in FIG. 8, when the amount of oil used for frying is small, the thermistor 5a slightly decreases in temperature of the oil. However, when the oil amount is large, the temperature change of the thermistor 5a does not follow the oil temperature change as shown in FIG. 10, and the measured temperature is within the judgment time Tconst. Since the temperature does not fall much below θconst, the set temperature cannot be corrected.
At point B, the temperature of the oil has not yet recovered, but only the temperature of the thermistor 5a has recovered, so cooking must be performed while the oil temperature is low, and the fried food will fail. It had the disadvantage of.
