Reference numeral 106 denotes a rice cooker cover that surrounds the rice cooker 98, and has a front wall that can be opened and closed. 107
Is a box-shaped rice collection box with wheels on the bottom and an open top 1
It is a rice carrier having 08. Next, the operation will be described together with the time chart. First, the lid 20
The rice is collected and supplied, and this rice is stored in the funnel inside the case. Next, turn the power "ON", open the main tap for water, gas, etc., operate each switch to set the rice cooking conditions and complete the work preparation, then turn the start switch "ON".
To Then, the motor 15 for measuring rice is driven to rotate the constant quantity supply roll 16, so that the rice is supplied to the guide funnel 18 by the constant quantity supply roll 16 by a predetermined amount. Then, the rice passes through the supply port 17 of the top plate 13, rotates the guide funnel opening / closing plate 87 downward, and falls into the tank 1.

After that, the amount of rice set in advance (the amount of rice discharged from the fixed amount supply roll 16 after one rotation is measured in advance is measured. Therefore, the number of rotations of the fixed amount supply roll 16 is taken in as a pulse. The motor 15 is stopped (measurement step) when the number reaches a value calculated by counting the number). In addition, in connection with "ON" of the start switch, the fan 86
Rotates to take in the outside air from the outside of the case 14 into the case, and then exhaust the air toward the bottom of the case 14. Therefore, since air flows in the case, it is possible to prevent the occurrence of dew condensation in the case and to cool the case to prevent malfunction or failure of the device due to high temperature and high humidity. When the weighing is finished, the guide funnel opening / closing plate 87 is returned to the original position by the spring 88 and the lower end opening of the guide funnel 18 is closed. Therefore, it is possible to reduce or prevent the moisture in the tank 1 from entering the fixed quantity supply roll 16 and the funnel storing the rice, so that the deterioration of the rice can be prevented. Further, when the inside of the tank 1 is washed with water, the water pressure can be increased, so that the cleaning effect can be enhanced and the generation of mold can be prevented.

Subsequently, when the motor 45 for washing rice is driven, the rotary shaft 43 receives rotational power through the transmission mechanism (motor shaft 46, gears 47, 48, etc.) and the rotary shaft 43 is provided integrally with the rotary shaft 43. All the stirring bodies 49 rotate in the same direction. Further, since the solenoid valve (upper water supply WV) 67 repeats “open” and “close” multiple times, in connection with this, from the main water supply pipe 64 to the solenoid valve (upper water supply WV) 67, the branch water supply pipe 65, both cylinders. The water that has passed through the body 61 is supplied from both shower bodies 62 to the tank 1. Therefore, the rice is agitated by the agitator 49 and abraded (abrading step). At this time, the sewage enters the water passage 29 through the tank 1 and the filter 25, is guided from the box 27 through the drain pipe 38 to a predetermined place.

After a predetermined time, the solenoid valve (lower water supply WV) 68 is opened and the solenoids 34 and 35 are energized and excited.
Then, from the main water supply pipe 64 to the solenoid valve (lower water supply WV) 68,
The water that has passed through the branch water supply pipe 66 enters the water channel 29 of the jacket 26. Also, the solenoids 34 and 35 are wire-3.
6 and 37 are pulled to rotate the valve actuating arms 32 and 33 about the center of the rotating shaft. In this connection, the valves 30 and 31 pushed by the valve actuating arms 32 and 33 move to the front side to close the communication holes communicating with the water channel 29. Therefore, since the water sent into the water channel enters the tank 1 through the filter 25, the water can be supplied from above and below the tank 1 to increase the amount of water supplied per hour.

When the water in the tank reaches a predetermined water level or higher, the water flows from the overflow port 2 to the overflow box 3
Then, the water is discharged from the box 27 through the drain pipe 38 to a predetermined drainage place. Therefore, foreign matter such as bran, small dust, and dust that floats in association with the rise of the water surface also flows from the tank 1 through the overflow box 39 together with the water.
Since it enters the flow tube 40, it is possible to enhance the separation and discharge of foreign substances mixed in rice. Further, even if rice rises in association with the rising of the water level, the separator 4 covers the overflow mouth 2, so that the rice does not overflow and the loss can be prevented. . Since the separator 4 is provided with a large number of small holes 3, water can flow through the small holes 3 from the overflow port 2 and overflow.

Even if foreign matter adheres to the small holes 3 of the separator 4 and causes clogging, a space is provided between the separator 4 and the inner surface of the tank 1, so that water passes through this space. From the overflow port 2, the overflow box 39 is entered and the overflow tube 40 is dropped. Therefore, the tank 1 is not filled with water. Then, the separating body 4 is an overflow of the tank 1.
Since it is hooked on the edge of the flow port 2, it can be easily attached to and detached from the tank 1, and inspection and cleaning can be performed easily.

The interval l ₁ between the upper edge of the hook portion 42 and the upper edge of the overflow opening 2 is equal to the lower edge of the hook portion 42 and the overedge.
The distance l ₂ between the lower edges of the flow openings 2 is greater than or equal to ₁ (l ₁ ≧ l ₂ ),
The distance l ₃ between the lower edge of the separator 4 and the lower edge of the overflow port 2
Wherein an l ₂ or more (l ₃ ≧ l _2), in a plan view of the space portion formed between the side wall and the tank 1 of the inner wall of the separator 4, the area S ₂ of the space portion O is - Bas - flow - greater than the area S ₁ of the mouth ₂ (S 2 ≧ S ₁₎ so are provided, Oh -
The flow-flow effect can be enhanced.

When the water level exceeds a predetermined level due to an accident, the float 72 also moves upward. When the magnet 73 faces the switch 76, the switch 76 is turned “ON” in association with this, and the electromagnetic valve (upper water supply WV) 67 is “closed” to stop the water supply. Since the water amount sensor 69 is provided with a guide 70 having a switch 76 inside the float 72, foreign matter such as bran can be prevented from adhering to the switch 76, and the float 72 can be moved up and down smoothly. Further, by adjusting the height of the guide mounting plate 78 (for example, inserting a spacer), the positional relationship between the switch 76 and the magnet 73 can be accurately matched. The guide mounting plate 78 can be easily attached / detached to / from the top plate 13 by operating the screw 77, and the float 72 can also be easily attached / detached by inserting / removing the float 72 into / from the top plate 13.

After that, the solenoid valve (lower water supply WV) 68 (in the embodiment, the solenoid valve (upper water supply WV) 67 is "closed" in advance) is closed, and the solenoids 30 and 31 are energized. And the drive of the motor 45 is stopped. In connection with this, the lower water supply is stopped, and the valves 30 and 31 open the water passage 29, so that the water in the tank is discharged to a predetermined place through the box 27 and the drain pipe 38, and the rotation of the stirring body 49 is stopped. Do (rinsing process). The rice washing work is completed after a rinsing process after polishing rice.

Next, the solenoid valve (lower water supply WV) 68 becomes "open" to energize both solenoids 30 and 31. Accordingly, the water in the main water supply pipe 64 enters the water passage 29 of the jacket 26 through the branch water supply pipe 66 and is stored in the tank 1 through the filter 25, so that the water level rises with the passage of time. Then, after a predetermined time, when the water becomes full, the switch 7
6 becomes "ON" and drives the motor 45 for a short time. Therefore, the agitator 49 also rotates for a short time in association with the driving of the motor 45 to level the rice layer. Then, after the rotation of the stirring body 49 is completed, the electromagnetic valve (lower water supply WV) 68 is closed. Then, when the energization of the solenoid 31 is stopped, the operation arm 33
Rotates in the opposite direction, in connection with which the valve 31 retracts and opens the water channel 29. Therefore, the water in the tank 1 enters the box through the filter 25, the water channel 29, and the holes and is guided to a predetermined place through the guide tube 38.

This is called "water addition / decrease" and the amount of water per unit time that enters the box through the water passage 29 and the hole is measured in advance. Therefore, by counting the energization time to the solenoid 31, The amount of water addition or subtraction can be calculated. When the energization time to the solenoid 31 corresponding to the amount of rice selected (set) in advance is reached, the motor 45 is driven to excite the solenoid 31. Then, the agitator 49 is rotated and agitated by driving the motor 45, and the valve 31 pushed by the actuating arm 33 which is pulled by the wire 37 and rotated is moved to the front side to close the water channel 29 ( Water addition process).

Next, the motor 45 is driven to rotate the rotary shaft 43.
Is rotated, the stirring body 49 also rotates in the same direction and is stirred. Further, since the motor 51 is driven to operate the cam mechanism 52, the valve shaft 50 and the valve 54 move downward. Then, the valve 54 opens the jacket 26, so that the tank 1
The washed rice and the water for cooking rice that has been adjusted in water fall into the rice cooker 80 through the passage of the filter 25.
It is collected in the inner pot. The operator holds the arm 81 and pulls it toward the front side to take out the rice cooker 80 to the front of the rice-washing and rice-cooking device 5. Then, after covering the inner pot, the arm 81 is pushed to the rear side of the rice cooker 80. Set it to the original position. Subsequently, the worker turns on the ignition switch to start rice cooking work.

When the rice and water are discharged, the drainage body 83
In the case where the valve is provided, the valve 54 is formed in a conical shape, so that the falling object falls in a parabolic shape in a front view, but the water hits the chevron-shaped draining body 83 and a rift is formed.
Therefore, the inside of the parabolic shape becomes the atmospheric pressure and the scattering of falling rice and water can be prevented, and the collection work by the container 85 can be facilitated. Then, when taking out the collected container 85, the arm 81 is held and pulled out to the near side where there is no trouble in taking out the container 85. In addition, since the upper surface of the draining member 83 is formed in a mountain shape, the draining effect can be enhanced, and since the draining member 83 is detachably provided, it can be replaced with one having a different length and can be adapted to the size of the container 85. .

When the rice discharging work is completed (dropping), the driving of the motors 45 and 51 is stopped and the solenoid valve (upper water supply WV) 67 is opened. Therefore, the agitation is stopped by stopping the driving of the motor 45, and the valve shaft 50 is moved upward by the stopping of the driving of the motor 51 so that the valve 54 is moved to the jacket 2.
Close the rice aisle of 6. Solenoid valve (upper water supply WV) 67 Opened for a predetermined time, and water is main water supply pipe 64, branch water supply pipe 65
And the like, and is supplied from the shower body 62 into the tank. Subsequently, the solenoid valve (lower water supply WV) 68 is opened, so that water flows through the branch water supply pipe 66 and the water channel 2 of the jacket 26.
9 and then through tank 25 into tank 1. When the excitation of the valve 30 is released, the operating arm 3
2 rotates and stops pushing against valve 30, so valve 3
0 retreats to open the waterway 29.

By this water supply operation, the inner surface of the tank 1 is washed with the shower water supplied from the shower body 62, and the filter 25 is washed (washed) with the water sent into the water passage 29. When the cleaning is finished, the electromagnetic valve (lower water supply WV) 68 is “closed”, and as described above, the electromagnetic valve (upper water supply WV) is “closed” to stop the water supply to the tank 1. Then, the excitation of the solenoid 31 is released, and in association with this, the valve 31 moves to the rear side and returns to the original position to open the water channel 29. Therefore, the water passage 29 and the box 27 communicate with each other at two locations facing both valves 30 and 31.

The embodiment shown in FIGS. 17 to 19 will be described. The rice washed in the washing section 89 is sent along with water to the feed pipe 9
It is supplied to the immersion tank 90 through 3 and is immersed therein for a predetermined time (for example, 60 minutes). Then, when the immersion is finished, the shutter 96 is opened and the rice and water drop and are collected by the rice cooker 98. Next, the rice cooking lid 104 is fixed to the opening 105 of the rice cooking device 98, and the rice cooking start switch 100 of the rice cooking panel 102 is turned on. Then, each work is performed according to the control program, and the rice cooking work is finished after a predetermined time. Subsequently, the worker sets the rice cooker lid 104 to the rice cooker 98.
Set the rice removal switch 101 from "ON". The rice cooker cover 106 is opened in advance and the rice carrier 106 is provided at a predetermined position below the rice cooker 98.

Then, the rice cooker 98 rotates to open the opening 1
Since 05 is moved to the lower side, the rice is dropped into the rice collection box 108 from the opening 105 and collected. When the rice is collected, the rice transport box 106 is moved to the next work place. Since this steam rice cooker is provided with an independent cleaning unit 89, the rice feeding (supplying) position is lowered and rice can be easily supplied. Further, since the washed rice can be dipped in the dipping tank 95 even in the rice cooking work state, the efficiency of the rice cooking work can be achieved.
