Is provided. Although not shown, the operation and work flow of each device is performed by a micro computer.
Data is automatically controlled. Further, two solenoids 31 are provided, but one rod
May be operated.

Next, the operation will be described. First, the operator operates the switches 20 such as the various switches and the rice cooking amount switch in the switch section of the operation panel 21 to set the rice cooking conditions, and turns on the work start switch.
The motor (19) is started by the microcomputer to rotate the rice feeder (17), and the grains (hereinafter, "rice" in this embodiment) stored in the grain tank (14) of the grain storage unit (9) are received in the receiving hole. 16. A fixed amount is supplied to the washing tank 1 through the communication port of the top plate 12 under the rice feeder guide 15.

Next, an "open" signal is output to the solenoid valve 54, and the motor 26 is started, so that the water sent from the water supply source passes through the water supply pipe 52 and the check valve 53, and is washed. The water is sprinkled inside, and the stirring shaft 27 and the stirring body 28 of the stirring device 23 rotate to stir and wash the water and rice.

At this time, the generated sewage enters the jacket 24 from the washing tank 1, enters the drain box 29 through the drain port 30, and is discharged to a predetermined place outside the machine via the drain pipe. When the cleaning operation is completed, the solenoid valve 54 closes,
Since the driving of the motor 26 is stopped, the water supply and the stirring are stopped.

In such a washing operation, the stirring shaft 27
Is formed at the upper portion of the cleaning tank 1 and extends from the central portion to the lower portion of the cleaning tank 1 because there is no shaft for vertically moving the elevating valve 2 through the central portion of the cleaning tank 1 in the vertical direction as in the related art. The agitation performance of rice and water can be improved and the washing effect can be enhanced by the large space.

When the sewage in the tank generated at the time of washing is drained (the time is controlled by the microcomputer),
The solenoid valve 54 opens, and the solenoid 31 is excited. Therefore, the drainage opening / closing valve pressing cam 48 is turned around the horizontal shaft 51 by the operating mechanism 32 and the rod 49 moving upward to push the spring 34 so that the drainage opening / closing valve 33 faces the drainage port 30. And the drain 30 is completely closed, so that the supplied water for cooking rice is supplied to the water supply pipe 52,
Water is supplied from above the cleaning tank 1 into the cleaning tank 1 through the check valve 53, and water is stored in the cleaning tank 1. When a predetermined amount of water is reached by a detecting means such as a full water sensor (not shown), the solenoid valve 54 is closed.

Subsequently, when another solenoid 31 is excited, the water outlet opening / closing valve pressing cam 46 is rotated about the horizontal axis 50 by the operating mechanism 32 and the rod 47 moving upward to press the spring 34. The drain opening / closing valve 33 is moved toward the drain 30 while the drain 30 is in a substantially half-open state. As a result, the water stored in the washing tank 1 is
4. Drained to a predetermined drain through the drain box 29.

When the amount of water in the washing tank 1 reaches a predetermined amount (the time is controlled by the microcomputer), the solenoid 31 is excited, so that the discharge port opening / closing valve pressing cam 4
Reference numeral 8 denotes a drain port 3 which is rotated about a horizontal axis 51 by an operating mechanism 32 and a rod 49 which moves upward, moves the drain port opening / closing valve 33 toward the drain port 30 while pressing the spring 34, and
0 is in the fully closed state. This completes the water adjustment work.

When the motor 40 is driven, the cam 39 rotates together with the rotating motor shaft 40a in the same direction to release the engagement with the lifting valve lifting frame 41. Therefore, the tip of the elevating valve elevating frame 41 pivots downward about the horizontal axis Y due to the weight of rice and water. At this time, the longitudinal axes 43 and 43 of the valve support 42, the connecting body 45, and the elevating valve 2 move downward to open the rice discharge port 25, so that the rice and water fall through the washing tank 1 and the jacket 24. Then, the rice cooker 59 enters the inner pot 56 through a receiving opening 60 formed in the lid 57 of the rice cooker 59 and is stored therein.

When the forward / reverse motor 65 rotates forward,
Since the screw shaft 64 rotates forward, the shutter 57 is moved laterally along the shutter opening / closing arm 59 and the guide rail 62 to close the receiving port 60. Subsequently, automatic ignition by the microcomputer or the operator turns on the ignition switch to start the rice cooking operation.

When the motor 40 is driven, the cam 39 rotates in the same direction as the motor shaft 40a which rotates in connection with the motor 40, and the cam 39 rotates with the lift valve raising / lowering frame 41. To the position.

In such a rice cooking operation, before the start of the cereal washing operation, after the end of the operation, during the operation,
Maintenance such as removal of foreign matters such as rice and bran remaining in the washing tank 1 and inspection and cleaning of the washing means may be performed. In this case, the cylinder of the washing tank 1 can be used without disassembling the washing tank 1. The window 5 can be opened by operating the lid 6 provided on the section 3 or the funnel section 4 with the opening and closing tool 37 with one touch, and can be easily performed from each of the windows 5 by visual observation, using a cleaning tool or the like.

When it is difficult to remove the deposits on the inner wall of the washing tank, or when it is difficult to reach the
When the funnel part 4 is removed from the cylindrical part 3 by operating the cylinder 6, the inside of the cylindrical part 3 and the inside of the funnel part 4 can be largely opened, so that the operator can inspect and clean even in the difficult place, and perform maintenance. Can be enhanced. Further, the convenience of separating and assembling the cylindrical portion 3 and the funnel portion 4 can be improved, and work efficiency can be improved by improving maintenance.
