The heater 18 is provided with a gas burner 48 at a central portion thereof, and a heat sensitive portion 49 which is constantly pressed upward and can be raised and lowered at the central portion of the gas burner 48. Reference numeral 50 denotes a pan that surrounds the gas burner 48 and is placed on the heater main body, and that has an upright surface 51 on the gas burner side. The lower end of the outer hook 19 is configured to be fixed to the measuring pan 50 by a fixing tool 52 (bolts and nuts in the embodiment) and a fixing plate 53. Next, the operation will be described. The rice stored in the rice storage 7 is measured and supplied to the washing tank 12 through the rice supply port, and then the supply is stopped when the rice reaches a predetermined amount. Subsequently, the rice is washed with water in the washing tank and the washing body 13 that rotates with water. The sewage generated at the time of washing is discharged to a predetermined drain through the washing tank 12, the water flow network 15, the drain jacket 14, and the like. When the washing operation is completed, the drain outlet is closed and a predetermined amount of water for cooking rice is supplied. When the reversible motor 29 is driven, the motor shaft 30 rotates, so that the metal 31 meshing with the motor shaft 30 moves to the left (in the direction of arrow A) in front view of the rice-washing / cooking apparatus 5. Thereafter, when the metal 31 hits the shutter open switch 40 and is turned on, the driving of the reversible motor 29 is stopped. Since the shutter opening / closing arm 26 moves in the same direction as the movement of the metal 31, the upright surface 28 pushes the handle 25 and moves in the same direction to open the receiving port 1. When the metal 31 moves, the metal 31 is inserted through the motor shaft 30 and the metal rotation preventing shaft 36, so that the rotation can be prevented. When the lifting shaft is lowered, the drop valve 16 is also lowered to open the rice discharge port. Then, the rice and the water for cooking rice in the washing tank fall from the rice discharge port and pass through the receiving port 1 and are stored in the inner pot 20. Subsequently, when the reversible motor 29 rotates in the reverse direction, the metal 31 and the shutter opening / closing arm 26 move rightward due to the reverse rotation of the motor shaft 30 (the side opposite to the direction of the arrow A).
Move in the direction of. Then, when the metal 31 hits the shutter closing switch 39 and is turned on, the driving of the reversible motor 29 is stopped. Accordingly, the upright surface 28 of the shutter opening / closing arm 26 pushes the handle 25 to move the shutter 4 to the right and close the receiving port 1. And each hole 4 of the shutter 4
The ball 44 is pushed by the spring 45 and fits in 2 to determine the position of the shutter 4. Thus, when the shutter 4 closes the receiving port 1, the shutter 4 is positioned and forced to move freely in the lateral direction. Next, the heater 18 is ignited and the inner pot 20 is heated to start cooking rice. After a predetermined time, a predetermined temperature (for example, 140 ° C.) is detected by the heat sensing unit 49 and the rice cooker switch is turned “off”. When the rice cooking operation is completed, the drawer table 47 is pulled out to the near side. At this time, the shutter opening / closing arm 26
Is provided with a groove 27 so that the handle 25 is
Get out of 7 smoothly. In addition, since the rice cooker 3 can be taken out with the rice cooker lid 2 put on the inner pot 20, dust and the like do not fall on the rice. In addition, since the heat after cooking does not escape, a decrease in taste can be prevented. When the rice cooker is to be cooked again after removing the inner pot 20 to take out the rice, the empty inner pot 20 is replaced with the outer pot 19.
And cover with rice cooker lid 2. Then, the drawer table 47 is pushed. Then, the handle 25 enters the groove 27 of the shutter opening / closing arm 26. At this time, even if the rice cooker 2 is inclined in plan view, the cover direction correcting roller 37 hits the shutter rail 21 to correct the direction. 4 moves smoothly. When the rice cooker 2 is slightly inclined, a cover direction correcting roller 37 that moves together with the shutter opening / closing arm 26 hits the shutter rail 21 to correct the direction of the rice cooker 2. When the handle 25 reaches a predetermined position, the handle 25 turns on the shutter set switch 38.
Since the circuit for driving the reversible motor 29 is connected, the rice cooker 2 is not driven unless it is at a predetermined position, such as when the rice cooker 2 is not present or when the rice cooker 2 is floating. And
Since the shutter 4 can be taken out simultaneously with the rice cooker lid 2, inspection and cleaning can be easily performed. Further, since the shutter stopper plate 23 can be removed, the cleaning including the shutter rail 21 is further facilitated. In addition, the lower end of the outer pot 19 is placed on the juice receiving tray 50 of the heater 18 and is fixed by the fixing tool 52 with the fixing plate 53 applied thereto.
9 can be prevented from floating or being displaced, so that the performance of sensing the temperature of the bottom wall of the inner pot by the heat-sensitive part 49 is improved. Although the operation of the shutter 4 of the rice cooker 3 on the right side in the front view of the rice washing rice cooker 5 has been described, the shutter 4 of the rice cooker 3 on the left opens the receiving port 1 when it moves to the right, On the other hand, when it moves to the left and returns to the original position, the structure is the same except that the structure for closing the receiving port 1 is different.
