With the intermittent rotation of the inner pot, the water and rice inside start to flow. Due to the flow of water and rice in the inner pot, the heat of the heated inner pot is distributed to each part of the inner pot, and the temperature of water and rice rises uniformly. On the other hand, the amount of rice cooked in the inner pot is detected by the weight sensor, and the temperature sensor constantly detects the temperature of the heated inner pot. When the temperature detected by the temperature sensor reaches the stop temperature corresponding to the amount of cooked rice, the rotation motor is turned off, and the intermittent rotation of the inner pot stops. Thereafter, when the stationary inner pot is heated for a certain period of time to reach the rice-cooking end temperature, the energization of the induction coil is stopped, and then the rice in the inner pot is cooked through the additional cooking step.

The cooked rice amount W detected by the weight sensor 24 is compared with a first set cooked rice amount W1 in step S4. If W <W1 as a result of the comparison, in step S5, for example, the amount of cooked rice is ranked as "small" of 3 cups or less, and the process proceeds directly to step S6. In step S6, the rice cooking temperature Ta detected by the lid sensor 20 becomes the first set stop temperature T

If 1 ≦ W ≦ W2, the amount of cooked rice is 4 to 6 in step S9.

果的に防止することができる。According to the experimental results of the present invention, it was confirmed that the unevenness of rice cooking due to the temperature difference corresponds to the amount of cooked rice. That is, when the amount of cooked rice is large, the convection of the water w in the inner pot is hindered in accordance with the amount of cooked rice. Therefore, the value of the set stop temperature T1 to T3 is T1 <T2 <T3
The relationship has been selected. That is, the stop temperature Ta of the intermittent rotation of the inner pot 2 depends on the amount of cooked rice W. When the amount of cooked rice W in the inner pot 2 is small, the intermittent rotation stops at a lower temperature than when it is large. I have. As a result, it is possible to effectively prevent the occurrence of uneven cooking of a large amount of cooked rice, which has a particularly high rate of uneven cooking, while effectively utilizing the driving power of the motor 11 of the rotating mechanism.

フにして内釜２の加熱を停止して炊飯工程が終了する。Even after the rotation of the inner pot 2 is stopped, the heating of the inner pot 2 of the induction coil 5 is continued on the other hand. As the rice cooks and approaches the boiling temperature, the properties of the rice r in the inner pot are softened and the gelatinization phenomenon starts. However, the rotation of the inner pot 2 is already stopped before the start of the gelatinization of the rice r, and the shape of the cooked rice is prevented from being collapsed. Thereafter, when the water w in the inner pot 2 disappears due to the boiling, the temperature of the inner pot 2 rapidly rises. The bottom sensor 13 detects the temperature of the inner pot 2 that has risen, and
At 14, the detected temperature Tb of the bottom sensor 13 is compared with the rice cooking end temperature T4. If Tb> T4 as a result of the comparison, the process proceeds to step S15, where the control unit 22 turns off the exciting current of the induction coil 5, stops heating the inner pot 2, and ends the rice cooking process.

A rice cooking amount detection unit and a rice cooking temperature detection unit for detecting a rice cooking amount and a rice cooking temperature during the rice cooking comprising the put rice and water; and a control unit for controlling a heating unit and a rotation unit. And the inner pot heated and rotated via the rotating means is stopped based on the stop temperature detected by the rice cooking temperature detecting means, and the stop temperature is set in accordance with the rice cooking amount detected by the rice cooking amount detecting means. A rice cooker was constructed. Further, a rice cooker was configured in which the stop temperature when the amount of cooked rice was small was set lower than the stop temperature when the amount of cooked rice was large.

Since the rotation of the inner pot is controlled on the basis of the detected temperature at which the properties of rice are changed by cooking rice, it is possible to prevent the shape of rice grains from being deformed due to gelatinization. Furthermore, since the amount of cooked rice detected by the cooked rice amount detecting means is ranked and the stop temperature is set, it is possible to cook delicious rice without unevenness from a small amount to a large amount without consuming unnecessary electric power to the rotating means. Can be. Therefore, according to the present invention, it is possible to provide a rice cooker that is economical and has high rice cooking accuracy without rice grain shape or uneven cooking.
