In 02, for example, if the number of kettles is five, "05" is displayed, and the total number of kettles indicator 103 is displayed as "00".

Therefore, the metering roll 64 discharges the rice into the guide cylinder 72 while rotating, and rotates when the predetermined rotational speed is reached. During this time, the rice sent to the guide cylinder 72 is
The rice enters the rice washing tank 151 through the input port 71 provided in the container.

Since the solenoid valve 82 which has received the control signal from the control section of the operation panel 97 opens, the water source (for example, water supply) is opened.
High-pressure water sent through the water supply pipe 76 and the base water supply pipe 77 from the water supply pipe 76 and the nozzle 80 through each water supply pipe 78.
From the rice washing tank 15 toward the center and the upper inner wall. At this time, since the solenoids 36 and 37 are not energized and are in a non-excited state, the valve shafts 30 and 31 and the valve 28
29 is moved rearward by the springs 42 and 43 to open the drain port 23 and the water adjusting port 26. Therefore, sewage containing foreign matter such as dust and debris generated during the rice washing operation enters the water channel 21 from the rice washing tank 15 through the net 16 of the jacket 18, and then passes through the openings 23 and 26 from the drain box 27 to the drain pipe 48. It is discharged to a predetermined place via. And
After a predetermined time, the transmission of the control signal to the electromagnetic valve 82 is stopped. In this connection, the electromagnetic valve 82 is closed to stop the water supply. Work is performed for a predetermined time (several tens of seconds). This rice polishing operation is performed a plurality of times during the rice washing operation.

After that, when the solenoids 36 and 37 are energized by being energized, the valve shafts 30 and 31 move to the longitudinal axes 38 and 39 and the link 3
With the aid of 4.35, it moves to the front side against the force of the springs 42 and 43, and closes the drain port 23 and the water adjusting port 26. When the solenoid valve 83 is energized to be excited, the water sent to the base water supply pipe 77 is diverted and a part of the water enters the water supply passage 49 through the lower water supply pipe 50, and then passes from the water passage 21 to the net 16. Through the rice washing tank. Therefore, each nozzle 80 is provided in the rice washing tank.
The water is increased by the upper water supply from the lower water supply pipe 50 and the lower water supply from the lower water supply pipe 50, so that the water supply time until reaching the amount of water to be overflowed at the end of the rice washing operation can be shortened, and the work efficiency can be reduced. Can be improved. Further, at this time, since the rice washing blade 14 is rotating, the foreign matter mixed into the rice can be easily separated in combination with the lower water supply, and the washing effect can be enhanced.
The overflowing water enters the overflow tube 47 from the overflow port 46 and falls into the drain box 27.
Thereafter, it is discharged to a predetermined place together with foreign matter through a drain pipe 48.

After a predetermined time, the solenoid valve 83 is closed to stop the lower water supply, the drain port 23 and the water adjusting port 26 are opened by stopping the power supply to both the solenoids 36 and 37, and the rotation of the rice washing blade 14 is stopped. The electromagnetic valve 82 is closed and the upper water supply is stopped in that order. Accordingly, the water stored in the rice washing tank 15 is discharged from the drain pipe 48 to a predetermined place through the net 16, the water channel 21, the drain port 23 and the drain box 27. At this time, since the water is discharged from both the drain port 23 and the water control port 26, the discharge time can be shortened, the work efficiency can be improved, and the lower surface of the water channel 21, that is, the upper surface of the lower lid 25 is inclined. The flow of water in the water channel 21 can be made smooth, and the amount of residual water can be significantly reduced. Therefore, the amount of foreign matter remaining can be greatly reduced.

Next, when the solenoids 36 and 37 are energized by being energized, the valve 28 closes the drain port 23 and the valve 29 closes the water control port 26 as described above. Subsequently, the solenoid valve 83 is opened to supply water to the rice washing tank 15 through the lower water supply, that is, the lower water supply pipe 50, the water supply passage 49, the water passage 21, and the net 16. Then, the water valve check timer is operated, and it is determined whether or not the overflow sensor 84 has been turned "ON" within a predetermined time. If it is determined that the overflow has not been reached, the electromagnetic valve 83 is closed and The energization of the solenoids 36 and 37 is stopped to perform an abnormality process, that is, an alarm is issued.

On the other hand, when the overflow sensor 84 senses, the solenoid valve 83 is closed after a short wait, and after a short wait, the power to both solenoids 37 is stopped and the solenoid 37 is de-energized. I do. In this connection, the lower water supply is stopped, and the valve shaft 31 and the valve 29 are moved to the rear side so that the water in the rice washing tank 15 is supplied to the water channel 21, the water supply channel 49, the water inlet / outlet 26.
Then, the water enters the drain pipe 48 through the drain box 27 and is discharged to a predetermined place. In this case, since the water addition / drainage port 26 is smaller than the diameter of the water discharge port 23, the water discharge amount from the water discharge port 23 is smaller than the water discharge amount per unit time, and the accuracy of water addition / drainage can be improved. Then, the power supply to the solenoid 37 is stopped when the time to reach the water amount for cooking calculated from the amount of cooked rice input by the worker, that is, when the water addition and subtraction time by the water addition and subtraction check timer times out. Accordingly, in connection with this, the valve 29 closes the water adjusting port 26 to end the water adjusting operation.

In addition, it is determined whether or not the overflow sensor 84 has been turned "OFF" during the water addition and subtraction operation.
If the water addition / detachment time has been reached even though it has not been turned "OFF", it is determined that an abnormality has occurred, and an alarm is issued by a notification buzzer.

Next, the rice washing blade rotating motor is driven to rotate the rice washing blade 14, and then the rice discharging motor is driven. Then, in connection with this, the vertical movement shaft 19 moves downward, so that the rice discharge valve 20 also moves in the same direction to open the rice passage 17. Therefore, the rice and water in the rice washing tank fall through the rice passage 17 into the inner pot 89 of the rice cooker 5, but at this time, the rice washing blades 14 are also rotating, so that the rice can be discharged smoothly and the remaining rice is removed. Can prevent rice.

When the rice discharging operation is completed, the driving of the rice washing blade rotating motor and the rice discharging motor is stopped, the power supply to both solenoids 36 and 37 is stopped, and the drain port 23 and the water level are adjusted. The mouths 26 are each opened. In addition, since the electromagnetic valve 83 is opened to supply water from the water supply channel 49 to the water channel 21, foreign matter, broken rice, and the like remaining in the water channel can be flushed from the drain port 23 and the water control port 26 to the drain box 27.

When the worker puts the lid 90 on the shuttle, the lid 90
Is in contact with the lid sensing actuator 94 so that the switch 9
Turn 3 ON. Then, after the predetermined immersion time is over, the operator turns on the ignition switch 105 to start the rice cooking operation. When the rice discharging and draining operation is completed, the rice discharging motor is reversed, the vertical shaft 19 is moved to a predetermined upper position, the rice passage 17 is closed by the rice discharging valve 20, and the rice weighing motor is then turned on. The metering roll 64 is driven to rotate, and the same operation as described above is performed to supply a predetermined amount of rice into the rice washing tank. Less than,
The same operation as above is performed until the rice washing operation.

When the rice washing operation is completed, it is determined whether or not the rice cooker set is OK immediately below. However, since the condition of the rice cooker OK, that is, "without lid" is not provided, "NO" is determined.
Next, it is determined whether or not the other kettle (the rice cooker 6 side in this embodiment) is set OK. However, since the lid 90 is not placed on the inner kettle, the switch 93 is turned OFF and the inner kettle 89 is set.
The switch 95 is turned "ON" because the pot and the inner pot sensing actuator 96 are in contact with each other.
5 is "OFF", so that the signal of the shuttle set OK is output. As a result, it is determined that the other shuttle set is present, and a drive command signal is sent to the motor 55 to drive the motor 55.

Then, the rotational power is transmitted through the motor shaft, the transmission collar 58, and the shaft of the rotating body 57, and
7 rotates counterclockwise in front view. At this time, the rotating body 57 moves to the left while sliding due to friction between the friction body provided on the outer peripheral surface and the upper surface of the rear connecting body 10, and the rice storage 3
And when the center switch of the rice washing device 4 and the limit switch 87 overlap in the vertical direction, the limit switch 87 is turned “ON”.
The output of the drive command signal to the motor 55 is stopped. Therefore, the rice passage 17 of the rice washing tank 15 is stopped at a position above the center of the inner pot 89. Next, rice removal
Then, the rice feed valve 20 is moved downward in the same direction to open the rice passage 17.
Thereby, the rice and water in the rice washing tank fall into the inner pot 89 of the rice cooker 6 through the rice passage 17 while being stirred by the rotating rice washing blades 14. Then, when the rice washing operation is completed, the driving of the rice washing blade rotating motor and the rice discharging motor is stopped, the power supply to both solenoids 36 and 37 is stopped, and the drain outlet 23 and the water inlet 26 are opened. . In addition, since the electromagnetic valve 83 is opened to supply water from the water supply channel 49 to the water channel 21, the residue in the water channel can be washed out, and cleaning after work can be facilitated.

Then, the worker puts the lid 90 on the pot and immerses it for a predetermined time, then turns on the ignition switch 105 to start the rice cooking operation. Next, after the rice discharging valve 20 is closed, the weighing and washing operation is performed as described above. Subsequently, it is determined whether or not it is the shuttle set OK immediately below. However, since the condition of the shuttle set OK, that is, “without lid” is not provided, “NO” is determined.
Next, it is determined whether or not the other kettle (the rice cooker 5 side in the embodiment) is set OK. However, since the other kettle is cooking rice, "NO" is determined and the process stands by on the spot.

When the rice storage 3 and the rice washing device 4 do not reach the predetermined position within a predetermined time from the start of the lateral movement, that is, when the monitoring timer is up, the output of the drive command signal to the motor 55 is stopped. An alarm is sounded with a buzzer to notify that it is abnormal.

When it is determined that the rice has been washed, the number of kettles displayed on the reserved kettle number display 102 is reduced by one. In addition, when the reserved shuttle increase button 99 or the reserved shuttle decrease button 100 is operated in the middle of the work, the display is performed by adding or subtracting one by one each time. Then, when the rice is washed, the number added by one is displayed on the accumulated pot number display device 103. Therefore, since the worker can grasp the number of remaining pots and the number of accumulated pots from these figures, it is possible to predict, for example, whether or not rice needs to be prepared, the work end time, and the like.
