Is configured such that the shutter 5 contacts the handle 4 at a position where the receiving opening 3 is opened. Reference numeral 60 denotes a frame cover provided between the reversible motor 53 and the rice cooker 2. Reference numeral 61 denotes a positioning ball of the shutter 5 which is provided at two positions (or at one or more positions) of each shutter guide 49 and is constantly pressed downward (lid side) by a spring 62. Reference numeral 63 denotes a hole into which the ball 61 fits when the shutter 5 moves to the center of the receiving port 3, and is provided in the same number as the balls 61. Next, the operation will be described. The rice stored in the rice storage 13 is separated from the bottom plate 16 by a measuring roll.
Is supplied to the washing tank 17 through the rice supply port. Then, when the set rice amount is reached, the measuring roll stops. Subsequently, the rice is washed by the rotating body 23 of the washing tool 18 which rotates with water in the washing tank. The sewage at the time of this washing is guided through a washing tank 17, a drainage network 26, a drainage jacket 19, and a drainage hole 28 to a predetermined drainage station. When the washing operation is completed, the valve 27 closes the drain port 28 and stores a predetermined amount of water for cooking rice supplied into the washing tank. When the reversible motor 53 is driven to rotate the motor shaft, the rotating arm 55 and the handle arm 52 of the moving body 7 rotate in the same direction. At this time, the grip arm 52 pushes the grip 4 and moves to one side to open the receiving port 3. The cam 56 also rotates in the same direction, turning the switch 59 "OFF" and turning the switch 58 "ON". When the switch 58 is turned on, the driving of the reversible motor 53 is stopped (see FIG. 9). When the cleaning operation is completed, the motor 38 is driven to rotate the motor shaft, and accordingly, the vertically movable arm operating body 42 and the cam 40 rotate in the direction of arrow a. Then, the vertical movement arm 34 is disengaged from the vertical movement arm operating body 42, and the drop valve shaft 32 becomes free. The drop valve 61 moves downward by the weight of the rice and the water for rice cooking and opens the discharge port 24. As a result, the rice and the water for cooking fall through the washing tank 17, the drainage network 26, and the discharge port 24, enter the inner pot 48 from the receiving port 3 of the lid 6, and are stored therein. At this time, one of the rotating vertical movement arms 34 is received by the position stay 37, and the other moves upward to turn on the switch 36. Further, the cam 40 sets the switch 43 to “OFF → ON → OFF” (see FIGS. 17 and 18). Further, in relation to the rotation of the vertically movable arm operating body 42, the vertically movable arm operating body 42 hits a pin 35 provided on the vertically movable arm 34 to rotate the vertically movable arm 34 in the direction of the arrow. . In this connection, the drop valve shaft 32 moves upward (see FIG. 19). When the vertically moving arm operating body 42 further rotates, the pin 35 intermittently enters the concave portion 41 and vertically moves the vertically moving arm 34 a plurality of times around the pivotal support. In connection with this, the drop valve shaft 32 and the drop valve 61 also move up and down the same number of times during the ascent (see FIG. 20). As described above, vibration is generated by moving the drop valve 61 up and down while the drop valve 61 is rising, so that the rice near the drop valve and on the drop valve 61 can be dropped and the vibration can also drain the water. . Thereafter, the vertically moving arm operating body 42 returns to the original position and closes the discharge port 24 by the drop valve 61. Another embodiment of FIG. 21 will be described. When the release switch 15 is pressed, the vertically movable arm operating body 44 rotates in the direction of arrow C to release the engagement with the pin 35, and the cam 45 turns the switch 43 "on". In connection with this, the drop valve shaft 32 and the drop valve 61 move downward to open the discharge port 24 (see FIG. 22). When the release switch 15 is pressed twice, the up-down moving arm operating body 44 rotates to the position shown in FIG. 23 and stops. Then, the switch for dropping 1 again
Pressing 5 moves the drop valve 24. Therefore, the worker can feel relieved because the movement of the drop valve 24 can be seen. When the storage of rice and water is completed, the reversible motor 53 is driven to rotate the motor shaft in the direction opposite to the previous rotation direction. In this connection, the grip arm rotating arm 55 and the grip arm 52 rotate in the same direction, push the grip 4 and move the shutter 5. Thereafter, the cam 56 turns the switch 58 "OFF" and the switch 59 "ON", so that the driving of the reversible motor 53 is stopped. At this time, the shutter 5 moves to the center of the lid 6 and closes the receiving port 3. When the rice is completely immersed in the inner pot 48 (continued if the rice has already been immersed in the washing tank), the ignition switch of the rice cooker 2 is turned on to start the rice cooking operation. When the rice cooking operation is completed, the rice cooker 2 is pulled out of the automatic rice cooker 8 in a front view. In this case, since the front side of the handle arm 52 of the moving body 7 is open, the handle 6 is held in a state where the inner pot 48 is covered with the lid 6 and the shutter 5 is closed in the receiving port 3 through which rice and water enter. The handle 4 can pass through this opening. Therefore, garbage and dust do not fall on the rice, which is sanitary. Since the lid 6 and the shutter 5 can be washed integrally, cleaning is easy. In addition, since the shutter type is used, the distance between the outlet 24 and the rice cooker 2 can be reduced, and the size can be reduced. Furthermore, since it can be taken out with the lid 6 covered, the steam in the inner pot does not escape and the taste is good. Since the driving means such as the motor 53 for operating the moving body 7 is located behind the rice cooker 2, steam does not enter, and the frame cover 60 shields the heat so that troubles can be prevented.
