The distributor port distributes a small amount of water to the measuring tank (2) and a large amount of water to the rice washing container 5 (6a). This distribution rate is determined by the amount of overflow in the measuring tank ■ (20
This is done by detecting the cutoff part (281) of the optical scale (to) with an optical sensor (not shown). Specifically, in the case of cooking about 5 cups of rice, about 101 servings of rice washing water and about 11 servings of rice cooking water are supplied. In this way, a large amount of water is supplied in a short time by tap pressure, and at the same time the stirring rod (6b) is rotated to wash the rice. At this time, the bottom opening of the rice washing container (6a) and the bottom plate were not completely sealed, allowing some water to leak out. As a result, the washed rice is drained out of the main body (1) from the drainage receiver (9) through the conveyor (7a) in sequence. Such rice washing is repeated until the turbidity of the waste water becomes below a predetermined value or a predetermined time elapses, and after the final washing, the first washing is repeated.
The flow control device f123 is closed and stops operating until drainage is completed. Thereafter, the conveyor (7a) swings so that the left side (7c) is on the lower side, and the bottom of the rice washing container (6a) is opened. Then, the second flow rate control device (to) is operated and water is supplied from the measuring tank (to) to the rice washing container (6a), and the rice is cooked while washing the rice stuck to the wall of the rice washing container (6a). supplied to The rice cooking water at this time needs to be measured accurately.This measurement is done when the 70-ton (70-ton), which is moving upwards due to the water supplied during rice washing, descends, and the slit on the optical scale (towards) is measured. ) (28a) is detected by the optical sensor. As a result, rice and a corresponding amount of water are placed in the rice cooker αω. Next, the i-transparent body (7a) is again swung to the drainage side, water is supplied for a predetermined period of time, and post-cleaning is performed. The position of the carrier (7a) is determined by the detection switch (8a),
(8b) and accurately controlled by the control device U. At the same time as post-cleaning, the lid holding device 1 (13) is activated, the holding of the lid (Lυ is released, and the lid αω is closed by its own weight. Meanwhile, the rice in the rice cooker αω is in a state where it has risen like a mountain. Then, a horizontal vibration is applied to the rice cooker α by an imaging stand (not shown) installed at the bottom of the rice cooker αO, and the rice inside the rice cooker opening is arranged evenly. A standby time is taken to soak the rice in water for a predetermined time, and power is supplied to the rice cooker 01.

The above is the case when the rice cooking switch (14b) is selected, but when the rice measuring switch (14a) is selected.

The carrier (7a) is swung toward the rice cooker α from the beginning.

The rice is weighed as described above, and the weighed rice passes through the rice washing container (6a) and is transferred to the rice cooker α via the conveyor (7a).
[It is stored inside and the lid is closed.]

Also, when the rice washing switch (14c) is selected.

The steps up to power supply to the rice cooker α1 are performed in the same manner as when the rice cooking switch (14b) is selected.
