Therefore, the movement of the shutter 31 can be regulated or freely moved by a simple means of moving the upper portion 50 of the handle 32 in the vertical direction, so that the operator can lift the rice cooking lid 29 by himself after the rice cooking operation and pinch his fingers. There is no safety.

Although not shown, the rice washing / cooking device 2 is constructed so as to be controlled by a microcomputer. Next, the operation will be described together with a part of the flowchart of FIG. First, to explain reserved rice, the selection switch 10 of the operation panel 12 is operated to input desired working conditions, and
For example, when the current time is 14:00 on Friday and the reserved time is set to 9:00 on Monday (see FIG. 14), the cleaning process starts at 14:00 on Saturday and 14:00 on Sunday, and the solenoid valve 25 is opened. By the excitation of the solenoid 22, the on-off valve 20 closes the drain port 19 to supply water and store water in the container 1 (see FIG. 15). Then, after a predetermined time, the solenoid valve 25 is de-energized to stop the water supply, and the solenoid 22 is de-energized so that the opening / closing valve 20 opens the drain port 19 and discharges the stored water in the container 1. Therefore, since the washing container 1 is washed before starting the work at the reserved time, it is possible to eliminate the adhesion of the bran and cook the rice with a good taste.

When it reaches 9:00 on Monday, the rice in the hopper is delivered by the delivery roll.
Then, the rice passes through the supply port (not shown) on the bottom plate and the container 1
To be housed. Further, the solenoid valve 25 becomes “open” and water is supplied from the nozzle through the water supply pipe 26 into the container. Then, the rotating body 15 rotates to stir and wash water and rice.
The wastewater generated at this time is discharged from the jacket 17 through the filter 18 and the drainage port 19.

After that, when the cleaning work is finished, the solenoid 22 is excited, so that the opening / closing valve 20 is moved forward by the moving shaft 21 by pressing the return spring 24 by the operating mechanism 23 to close the drainage port 19. Although not shown, the water level valve (not shown) is also closed by the same operation. Next, the electromagnetic valve 25 changes from “closed” to “open”, and water is supplied from the nozzle to the container 1 through the water supply pipe 26.
When the water is full, the solenoid valve 25 is closed and the water supply is stopped.

Next, when the solenoid 22 is de-energized, the water level valve returns to its original position by the spring 24. In this connection, the water in the container is filtered by the filter 1.
8. The water is discharged through the water level port and the drainage jacket 17.
After a predetermined time, that is, when the water level reaches a predetermined level, the solenoid 22 is excited again and the water level valve closes the water level port by an operating mechanism or the like.

When the dropping valve descends, the water and rice contained in the container 1 fall from the rice discharge port and pass through the rice supply port 33 to be contained in the inner pot 28. After that, the drop valve rises and closes the rice discharge port. Subsequently, when the forward / reverse rotation motor 43 reversely rotates and returns to the original position (a), the stop position detection switch 48 is turned on. Then, the forward / reverse rotation motor 43 is stopped. In connection with this, the shutter return spring 3
The shutter 31 pulled by 9 moves to close the rice supply port 33. At this time, the shutter 31 is received by the connecting plate 40.

The ignition switch is turned "ON" to start the rice cooking operation (when the rice is immersed in the inner pot, the rice cooking operation is started after a predetermined time). After that, when cooking is finished, the rice cooker 30 is pulled out. Next, when supplying rice and water to the rice cooker 30 on the left side when viewed from the front, the forward / reverse rotation motor 43 rotates in the reverse direction.
Then, the shutter opening / closing arm 45 rotates in the direction of arrow B to hit the handle 32 and the shutter return spring 3
The rice supply port 33 is opened by pushing and moving it against the force of 9.
After that, when the inner pot 28 stores rice and water, the forward / reverse rotation motor 4
3 rotates forward and returns the shutter opening / closing arm 45 to the original position, so that the shutter 31 also returns to the original position and the rice supply port 33
Close.

As described above, since the shutter 31 can be opened / closed by one shutter opening / closing arm 445, it is inexpensive and the structure is simple. Further, since the shutter opening / closing device 42 can be provided in the middle portion of the rice cooker 30 and the rice cooker 30, the space between the rice cookers can be effectively used.
