The rice washing section 2 is provided with a rice washing blade 19 and the like on a cylindrical rice washing cylinder 19 having an upper end portion detachably attached to the lower surface of the lower plate 12 and an outer peripheral surface of a rotatable hollow shaft 20.
The rice washing cylinder 19 has a tapered lower portion and an open lower end, and a net 21 having a large number of drainage holes on the lower end portion that does not allow rice to pass along the extension of the tapered slope, and is provided at the bottom portion. A conical valve 24 for opening and closing a drainage jacket 23 having a rice discharge hole 22 is detachably mounted, and an opening / closing shaft 26 provided to be vertically movable by a forward / reverse rotation motor 25 is provided.

Reference numeral 27 denotes a water supply pipe which communicates with a water source. The water supply pipe 27 is provided so as to be able to communicate with the drainage jacket 23 via an electromagnetic valve 28, and is connected to an upper water supply device 29 having a shower structure which looks through the lower plate 12 to the rice washing tank 19. It is provided so as to be able to communicate via the electromagnetic valve 30. The motor 31 rotates the hollow shaft 20 via a transmission mechanism.

The guide funnel 32 is formed in a funnel shape with upper and lower end faces opened. The upper opening is viewed through the rice discharging roll 9, and the lower opening is communicated with the rice washing tank 19. The lower plate 12 is detachably mounted on the lower plate 12 so as to face a communication hole 33 provided in the plate.

The rice cooker 3 includes a pot 34 located below the rice discharge hole 22 and a heating means (gas in the embodiment) 35 for heating the pot 34. The block circuit of FIG. 2 will be described. Reference numeral 36 denotes an arithmetic control unit (hereinafter referred to as a CPU) of a microcomputer having a memory 37.
Performs arithmetic operations and comparison / logic operations.

The information input to the CPU 36 via the input interface 38 includes the rice washing information from the rice washing switch 39, the normal rice or non-washing rice operation information from the operation changeover switch 40, and the rice storage amount detection sensor 6. And the operation information from an operation switch (for example, rice cooking amount, rice cooking, hardness adjustment, etc.) 41.

The command signals output from the CPU 36 via the output interface 42 include a drive signal for a motor (not shown) for driving the rice discharging roll 9, a drive signal for driving the motors 25 and 31, and a solenoid valve. Drive signal for opening and closing 28, 30 and actuating heating means 35 (eg, ignition)
Signal.

When the CPU 36 inputs a non-washing rice operation, the CPU 36 sets the driving time to the motor 31 shorter than that in the normal operation. In this case, the output of the drive command signal to the motor 31 may be in an “OFF” state, and when the motor 31 is a variable speed motor, the motor 31 may be configured to rotate at a low speed. Also,
When supplying cooked water, the "open" time of the solenoid valve 30 is set longer than during normal rice work. In addition, the start of the output of the ignition command signal of the ignition means 35 after the rice cooker 34 stores the rice and the cooking water is set to be longer than in the case of normal rice.

Next, the operation will be described. First, the door 18 is opened to supply a predetermined amount of rice (for example, 60 kg, 30 kg, or the like) to the rice storage 7, and then the normal rice operation is selected by the operation changeover switch 40 and the rice cooked amount is operated by the operation switch 41. (For example, 5 kg), the rice washing switch 39 and the rice cooking switch 41 are set to “O”.
N ".

Then, the CPU 36 drives the motor via the output interface 42 for a predetermined time, so that the rice discharging roll 9 also rotates in association with the rotation and the rice is transferred from the rice storage 7 to the rice washing tank 19 via the guiding funnel 32. Supply. And
After the elapse of a predetermined time, the output of the drive signal from the CPU 36 is stopped, so that the rotation of the rice discharging roll 9 is also stopped.

Next, the CPU 36 causes the solenoid valve 30 to "open".
Output a signal. Then, the water sent through the water supply pipe 27 is supplied from the upper water supply body 29 into the rice washing tank. Further, since the CPU 36 outputs a drive signal to the motor 31, the motor 31 rotates to rotate the hollow shaft 20 and the rice washing blade 4. Therefore, the rice in the rice washing tank is stirred by the rice washing blade 4, while the contaminated water enters the drain jacket 23 from the net 21 and is then drained to the outside.

When a predetermined time has elapsed (about 5 minutes), the CPU 3
Since the output of the drive signal from the motor 6 is stopped, the rotation of the motor 31 and the rice washing blade 4 is also stopped. Further, since the output of the “open” signal of the electromagnetic valve 30 from the CPU 36 is stopped, the water supply from the upper water supply body 29 is stopped.

Next, when the CPU 36 outputs an "open" signal to the electromagnetic valve 28, the water sent through the water supply pipe 27 enters the rice washing tank through the drainage jacket 23 and the net 21. Foreign matter (for example, dust and dirt) that enters and floats is floated by water and then discharged out of the rice washing tank through the overflow port of the rice washing tank 19. When a predetermined time has elapsed, the CPU 36 stops outputting the electromagnetic valve 28 "open" signal.

Then, the CPU 36 sets the drain jacket 23
Of the rice washing tank is drained to the outside through the drainage jacket 23 from the net 21. Thereafter, the CPU 36 closes the drain valve.
Since the signal is output and the drain jacket 23 is closed and then the "open" signal of the solenoid valve 30 is output, the water for cooking rice (rice for cooking) is supplied from the upper water supply body 29 into the rice washing tank.
Then, when the CPU 36 determines that it is the water supply time corresponding to the preset rice cooking amount, the output of the “open” signal of the solenoid valve 3 is stopped.

Next, when the CPU 36 outputs a drive command signal to the forward / reverse rotation motor 25, the opening / closing shaft 26 moves downward by a predetermined length and stops in connection therewith. The water falls through the drainage hole 22 of the drainage jacket 23 into the kettle 34. After a predetermined time, the CPU 36 outputs a drive command signal for reverse rotation to the forward / reverse rotation motor 25. Then, the forward / reverse rotation motor 25 reversely rotates to move the opening / closing shaft 26 upward, and stops rotating when it reaches the original position.

After the rice stored in the pot 34 is immersed here for a predetermined time (about 20 minutes), the CPU 36 instructs the heating means 35 to ignite and starts the rice cooking operation. The work changeover switch 4
When the non-washing rice work is selected at 0, the drive command time of the motor 31 output from the CPU 36 is set to the time during normal rice work (about 5
Minutes) (about 2 minutes). Therefore, while preventing damage to the rice, foreign matters (such as dust and bran) mixed in the rice can be discharged to enhance the cleaning effect.

In addition, when supplying the cooking water, the CPU 3
Reference numeral 6 indicates that the output time of the "open" signal to the solenoid valve 30 is slightly longer than that of the normal U.S. time. Then, since the cooked water can be supplied into the rice washing tank more than in the normal rice time, the CPU 36 outputs the ignition command signal to the heating means 35 later than the normal rice time. Therefore, the rice is stored in the rice washing tank 7 and the pot 34.
Water can be absorbed sufficiently, so that plump and tasty rice can be cooked.

In this embodiment, the rice is immersed in the pot 34. However, when the rice is immersed in the rice washing tank, the output of the drive signal output from the CPU 36 to the forward / reverse rotation motor 25 may be made slower than in the case of ordinary rice. .
