It is configured to automatically control the ``supply'' and ``stop'' of hot water supply. Further, this microcomputer is configured to notify that the rice quantity 12 is set in the case 7, and to start the motor 27 after detecting that the rice quantity 12 has been set. In this embodiment, the work is performed by selecting start/stop f of the motor 27, but an electromagnetic clutch may be used to turn on/off the power from the motor 27.

Next, the operation will be explained. First, a predetermined amount of pre-soaked grains (hereinafter referred to as rice) is supplied to the inner rotating body 2 via appropriate means. (Figure 13 Exit) At this time, some water is also supplied along with the rice (Figure 13 C).

Next, the microcomputer starts the motor 27. Then, this rotational power is transferred to the drive sprocket 28. It is transmitted to the chino 29 and the transmission sprocket 26. Accordingly, the gear 22 meshing with the toothed portion 25a of the transmission body 25 also rotates in the direction of the arrow in relation to this, and water is discharged from the outlet 4 (FIG. 13-2). Next, a steam supply command signal is output, and after a predetermined period of time, the output signal is stopped. Therefore, during that time, the steam sent through the steam purifier and the steam guide pipe 30 and ejected from the steam jet hole 30a passes through the small hole 2 and heats the rice stored in the inner rotating body 3 to steam it. (See Figure 13). Next, the motor 27 is started again to rotate the outer rotating body 5 in the direction of the arrow (toward FIG. 13), and then a hot water supply command signal is output. Then, the hot water sent through the water heater and the hot water guide pipe 31 is discharged from the hot water discharge hole and is supplied to both the inner and outer tanks 3 and 5 in a predetermined amount (the amount that the rice layer is flooded with). After dipping for a predetermined time (Fig. 13 H), the motor 2
7 and rotates the outer rotating body 5 in the direction of the arrow to drain water from the outlet 4 (Figure 13). Next, a steam supply command signal is output, and the output is stopped after a predetermined period of time has elapsed. Therefore, during that time, the steam ejected from the steam ejection hole 30a passes through the small hole 2 and heats the rice stored in the inner rotary body 3, thereby steaming and cooking the rice (FIG. 13 N). and,
After the rice cooking is finished, the microcomputer outputs a notification command signal to the notification means (for example, a lamp, a buzzer, a voice synthesizer, etc.) to notify the completion of the rice cooking, so that the worker moves the rice receiver 13 to the entrance 9.
(Note that if you have an automatic feeding device, it will be fed automatically.) Then, when the completion of setting is detected, the motor 27 is started to rotate the inner rotating body 3 in the direction of the arrow. (Figure 13). Then, the rice is collected from the take-out ports 1 and 4 through the collection port 12 into the rice receiver 13 (see Fig. 13), and then goes through the next work process 4. such as plating and packaging. be transferred.

In this way, although the rice cooking apparatus is compact, it is possible to cook rice with good taste by steam cooking.
