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

Next, the operation will be described. First, rice is supplied to the rice storage 8, and then various switches for setting the amount of cooked rice, the hardness, the degree of rice washing, etc. are operated to select a desired condition. Then, press the work switch to start the work
When set to "N", the discharged rice roll 9 rotates to guide the rice to the funnel 2
8. The rice is discharged from the communication hole 29 to the rice washing cylinder 16. When the amount of rice discharged reaches a predetermined amount, the rice discharging roll 9 stops rotating to stop the rice discharging operation.

Next, the hollow shaft 17 and the rice-washing blade 18 rotate to sharpen the rice, and the solenoid valve 25 opens to supply water from the water supply pipe 24 to the rice-washing cylinder 16. Therefore, the rice undergoes both polishing and washing in the washing cylinder. Then, the sewage generated by washing rice enters the drainage jacket 21 from the net 19, and is discharged from the drainage port of the drainage jacket 21 to the predetermined place through the drainage box 26. When the washing work is completed after a predetermined time has passed, the on-off valve 27 closes the drain port of the drain jacket 21,
Further, when a predetermined amount of water for cooking rice is supplied into the washing rice cylinder (when the water adjustment work is completed), the electromagnetic valve 25 is closed to stop the 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 pass through the rice discharging hole 20 and the receiving port 39 and fall into the inner pot 31 to be stored therein. After a predetermined time, the shutter 38 opens the inner pot lid. The receptacle 39 of 37 is closed. When the preparation for the rice cooking work is completed, the worker turns on the ignition switch 43 to start the rice cooking. After that, when each of the rice cooking and the wiping operation is completed, the operator lifts the lid opening / closing arm 42 and moves the inner pot lid 37 to a position higher than the inner pot 31. In connection with this, the wire-52 rotates the actuating body 48 downward, that is, in the direction of arrow a to move the vertical movement shaft 47 and the inner pot temperature sensor 46 downward.

Next, when the grip portion 40 of the drawer 35 is held and pulled toward the front side, the drawer plate 33 is moved to the front side (takeout side).
The outer hook 32 and the inner hook 31 supported by the outer hook 32 are moved to the take-out side. During this movement, the inner pot 31 and the outer pot 32 can move independently of the heater 2 which is a heating source, so that the operator can
Can be taken out and the working condition can be easily performed. Further, since the inner pot temperature sensor 46 is located below the virtual movement path of the inner pot 31 when the inner pot lid 37 is moved upward,
It does not hinder the work of taking out the inner pot 31. In addition, since the heat source gas pipe, electric wire, etc. do not expand or contract, or move, it is possible to prevent cracking or damage due to bending, for example. Then, the inner pot 31 of the rice cooker 1 that has moved to a predetermined position is lifted and taken out, and the inner pot 31 is transferred to a container.

Subsequently, when performing work, a new inner pot 31 is set on the outer pot 32, and then the grip portion 40 is held and pushed to a predetermined position on the back (rear) side. Then, when the lid opening / closing arm 42 is held and lowered to a predetermined position on the lower side, the inner pot 37 also moves downward in relation to this and the inner pot 31 is closed. In this case, since the actuating body 48 is rotated by the wire 52 in the direction opposite to the arrow A, the up-and-down moving 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. To do. Therefore, at the time of rice cooking work, the inner pot temperature sensor 46 detects the temperature of the inner pot 31 and outputs temperature information, and in connection with this, the rice cooker control suitable for the work (for example, the heating amount. Temperature, etc.) can be performed.
