The vertical movement shaft 47 is configured to move downward. In addition,
Each operation is controlled by a microcomputer (not shown).

Next, the operation will be described. First, after rice is supplied to the rice storage 8, a desired condition is selected by operating various switches for setting the amount of cooked rice, the hardness, the degree of rice washing, and the like. Next, set the work switch for starting the work to "O
N ", the rice discharging roll 9 rotates to guide the rice into the guiding funnel 2.
8. Discharge to the rice washing cylinder 16 from the communication hole 29. When the rice discharge amount reaches the predetermined amount, the rice discharge roll 9 stops rotating and stops the rice discharge operation.

Next, the hollow shaft 17 and the rice washing blade 18 rotate to grind the rice, and the solenoid valve 25 is opened to supply water from the water supply pipe 24 to the rice washing cylinder 16. Therefore, the rice is subjected to both polishing and washing in the washing cylinder. Then, the wastewater generated by the rice washing enters the drain jacket 21 from the net 19 and is discharged from the drain port of the drain jacket 21 through the drain box 26 to a predetermined place. When the rice washing operation is completed after a lapse of a predetermined time, the on-off valve 27 closes the drain port of the drain jacket 21,
Also, when a predetermined amount of water for cooking rice is supplied into the rice washing cylinder (when the water adjustment operation is completed), the electromagnetic valve 25 is closed to stop water supply.

When the opening / closing shaft 23 moves downward,
Since the valve 22 opens the rice discharging hole 20, the rice and water in the rice washing cylinder drop through the rice discharging hole 20 and the receiving port 39 into the inner pot 31 and are stored therein. The receiving port 39 of 37 is closed. When the preparation for the rice cooking operation is completed, the operator turns on the ignition switch 43 and starts the rice cooking. Thereafter, when the rice cooking and rice washing operations are completed, the operator lifts the lid opening / closing arm 42 upward and moves the inner pot cover 37 to a position higher than the inner pot 31. In this connection, the wire 52 rotates the operating body 48 downward, that is, in the direction of arrow A, to move the vertical movement shaft 47 and the inner hook temperature sensor 46 downward.

Next, when the user pulls the gripper 40 of the drawer 35 toward the front side while holding the grip portion 40, the drawer plate 33 is moved forward (the takeout side).
To move the outer shuttle 32 and the inner shuttle 31 supported by the outer shuttle 32 to the take-out side. During this movement, the inner pot 31 and the outer pot 32 can move independently of the heater 2 as a heating source.
Take out and work state can be done easily. Further, since the inner pot temperature sensor 46 is located below the virtual movement trajectory of the inner pot 31 when the inner pot lid 37 is moving upward,
There is no hindrance to taking out the inner pot 31. Further, since there is no expansion or contraction or movement of the gas pipe or electric wire of the heat source, it is possible to prevent, for example, cracks or breakage due to bending. Then, the inner pot 31 of the rice cooker 1 moved to a predetermined position is lifted and taken out, and is transferred from the inner pot 31 to a container.

Subsequently, when performing a work, the new inner hook 31 is set in the outer hook 32, and then the grip 40 is pushed to a predetermined position on the back (rear) side with the grip portion 40. Then, when the user holds the lid opening / closing arm 42 and lowers it to a predetermined lower position, the inner shuttle 37 also moves downward in relation thereto, and the inner shuttle 31 is closed. In this case, the operating body 48 is rotated in the direction opposite to the arrow A by the wire 52, so that the vertical movement shaft 47 moves upward to bring the inner pot temperature sensor 47 into contact with the outer surface of the bottom wall of the inner pot 31. I do. Therefore, at the time of the rice cooking operation, the inner pot temperature sensor 46 detects the temperature of the inner pot 31 and outputs the temperature information. Temperature, etc.).
