I have. Further, leg frames 16 are provided at the lower end portions of the two columns 14. The rear plate 11 is detachably provided on the support 14.
[0010]
In addition, a cover plate 17 is provided at the upper opening of the rice storage 7, and the cover plate 17 is formed on an opening / closing door 18 which is provided to be rotatable in the vertical direction from the front end to the center. . The rice washing section 2 includes a cylindrical rice washing cylinder 19 having an upper end detachably attached to the lower surface of the lower plate 12, a rice washing blade 4 on the outer peripheral surface of a rotatable hollow shaft 20, and the like. The rice washing cylinder 19 is formed with 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 is provided so that rice does not pass through 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.
[0011]
Numeral 27 denotes a water supply pipe communicating with a water source. The water supply pipe 27 is provided so as to be able to communicate with the drainage jacket 23 through an electromagnetic valve 28, and is provided with an electromagnetic valve 30 through a lower plate 12 to a rice washing tank 19 in a shower configuration. Are provided so as to communicate with each other. A motor 31 rotates the hollow shaft 20 via a transmission mechanism.
[0012]
The guide funnel 32 is formed in a funnel shape with upper and lower end faces opened. The upper opening is viewed from the rice discharging roll 9, and the lower opening is provided on the lower plate so as to communicate with the rice washing tank 19. And is detachably attached to the lower plate 12.
[0013]
The rice cooker 3 includes a kettle 34 located below the rice discharging hole 22 and a heating means (gas in the embodiment) 35 for heating the kettle 34. Referring to the block circuit shown in FIG. 2, reference numeral 36 denotes an arithmetic control unit (hereinafter referred to as a CPU) of a microcomputer having a memory 37, which performs an arithmetic operation and a comparison / logic operation.
[0014]
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 from the rice storage amount detection sensor 6. There are amount information and operation information from operation switches (for example, rice cooking amount, rice cooking, hardness adjustment, etc.) 41.
[0015]
The command signal output from the CPU 36 via the output interface 42 includes 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 the electromagnetic valves 28 and 30. And a signal for operating the heating means 35 (eg, ignition).
[0016]
In addition, when the CPU 36 inputs the non-washing rice work, the CPU 36 sets the drive time to the motor 31 shorter than that in the normal work. 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. In addition, when supplying cooked water, the "open" time of the solenoid valve 30 is set longer than during normal rice work. Further, 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 rice cooking water is set to be longer than in the case of normal rice.
In other words, normal rice is washed with normal rice washing intensity according to the standard rotation state of the rice washing blade 4, and non-washed rice is washed with a rotation state weaker than the rice washing intensity of the standard rice washing blade 4.
[0017]
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 amount of rice cooked by the operation switch 41. (For example, 5 kg), the rice washing switch 39 and the rice cooking switch 41 are turned “ON”.
[0018]
Then, the CPU 36 drives the motor through the output interface 42 for a predetermined time, so that the rice discharging roll 9 rotates in association with the rotation, and supplies the rice from the rice storage 7 to the rice washing tank 19 via the guiding funnel 32. Then, when a predetermined time has elapsed, 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.
[0019]
Next, the CPU 36 outputs an “open” signal to the solenoid valve 30. 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.
[0020]
After a lapse of a predetermined time (about 5 minutes), the output of the drive signal from the CPU 36 is stopped, and 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.
[0021]
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 through the net 21 and enters the rice washing tank. The mixed foreign matter (for example, dust and dirt) floats with water, and is discharged from the overflow port of the rice washing tank 19 to the outside of the rice washing tank. When a predetermined time has elapsed, the CPU 36 stops outputting the electromagnetic valve 28 "open" signal.
[0022]
Then, the CPU 36 outputs a drain valve (not shown) “open” signal of the drain jacket 23, so that the water in the rice washing tank is drained from the net 21 to the outside through the drain jacket 23. Thereafter, the CPU 36 outputs a drain valve “closed” signal and closes the drain jacket 23 and then outputs an “open” signal of the solenoid valve 30, so that the water for cooking rice (cooked water) is washed from the upper water supply body 29. It is supplied into the 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.
[0023]
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, so that the cooked water in the rice washing tank and the rice are drained into the drain jacket 23. Through the drain hole 22 of the tank. 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 rotates in the reverse direction to move the opening / closing shaft 26 upward, and stops rotating when it reaches the original position.
[0024]
After the rice stored in the pot 34 is dipped therein for a predetermined time (about 20 minutes), the CPU 36 instructs the heating means 35 to ignite and starts the rice cooking operation. When the non-washing rice work is selected by the work changeover switch 40, the drive command time of the motor 31 output from the CPU 36 is shorter (about 2 minutes) than during normal rice work (about 5 minutes). Therefore, while preventing damage to the rice, foreign matters (such as dust and bran) mixed in the rice can be discharged and the cleaning effect can be enhanced.
[0025]
In addition, when supplying the cooking water, the CPU 36 sets the output time of the “open” signal to the electromagnetic valve 30 to be slightly longer than that in the normal rice time. Then, the rice cooker can supply more cooked water to the rice washing tank than the normal rice time, and the CPU 36 outputs the ignition command signal to the heating means 35 later than the normal rice time. Therefore, the rice can sufficiently absorb water in the rice washing tank 7 and the pot 34, so that plump and tasty rice can be cooked.
[0026]
In this embodiment, the rice is immersed in the kettle 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.
