Further, at the lowest part of the main body 1, a drainage receiver 9 is provided for receiving and discharging water flowing down from the right end 8b when the carrier 8a swings with its right end 8b facing down. Also,
The rice cooker 10 is disposed at a position where it can receive water and rice flowing down from the left end 8c when the carrier 8a swings with its left end 8c facing down. The lid 11 of the rice cooker 10 is opened so that rice and water that has flowed down can enter the pot. At that time, as shown in FIG. 3, the differential holding device 12 installed at a predetermined position in the main body l holds the handle 11a formed on the top surface of the lid 11, and holds the lid 11 open halfway, that is, at an angle of 900 degrees or less. Hold open. The rice cooker 10 supports a lid 11 with a hinge mechanism so that it can be opened on one side, and has a latch mechanism for the lid 11 on the other end side. The differential holding device 12 is shown in FIGS. 4(a) and 4(b).

Set it so that it opens. The plate material 13a is fixed within the main body 1. Also, 17 is a limit switch,
This is for determining whether the differential holding device 12 is holding the lid 11 or not. As shown in Fig. 4(a), the lid holder [
12 does not hold the lid 11, the plates 13a, 1
One end of the plate 13b is wide open, and one end of the plate 13b comes into contact with the contact 17a of the limit switch 17, activating it. Electromagnet 15 and limit switch 17 are connected to control device 6 . When setting the rice cooker 10 inside the main body 1, as shown in FIG.
The handle 11a is held between the other ends, and the spring force of the coil spring 16 holds the lid 11 in the middle-open state. To release this holding, the electromagnet 15 is energized by a signal from the control device 6, one end of the plate 13b is attracted to the electromagnet 15, and the handle 11a is released. Therefore, the lid 11 rotates downward under its own weight, and the latch mechanism is activated by the force of the rotation, thereby closing the lid 11. However, the lid 11 may not close completely, and if cushioning is provided to reduce the impact when the lid 11 falls due to its own weight, the lid 11 will be difficult to close completely. For this reason, a lid closing device 20 was provided as shown in FIG.

In FIG. 5(a), 2), reference numeral 21 denotes a motor fixed within the main body l via a mounting member 25, and an arm J-23 is rotatably attached to the motor 21 via a gear 22.

Further, 24 is a limit switch that detects that the arm 23 is not performing a lid closing operation and notifies the control device 6 of the detection. The motor 21 is controlled by the control device 6. Also, 1
8a.

18b is a limit switch provided below the conveyor 8a; 19 is a control display board provided at the top of the main body 1 and connected to the control device 6; the control display board 19 controls everything up to rice weighing; Selection switches such as a rice measuring switch 19a, a rice cooking switch 19b for controlling rice cooking, and a rice washing switch 19c for controlling rice washing are provided.

Next, the operation of the above-mentioned conventional device will be explained using the flowchart shown in FIG. First, if the rice is not properly put into the rice storage chamber 2), then the lid 11 of the rice cooker 1° is latched to the open position by the differential holding device 12, and the rice cooking amount adjustment section of the control device 6 and set the rice cooking time adjustment section. Next trap, the selection switches 19a to 19c'i are selected to select the extent of the operation to be performed. Now, when the rice cooking switch 19b is selected, the control device 6 determines whether or not the lid 1 is open based on the signal from the limit switch 17, and if the limit switch 17 is on, that is, the lid 11 is held, the timer is activated. It enters a standby state until the set operation start time. if,
If the limit switch 17 is off, the operation is stopped and the user is immediately notified by an alarm or the like. Next, when the timer-set operation start time comes, the conveyor 8a moves to the drainage side (
2). At this time, the bottom opening of the rice washing container 4a is closed by the bottom plate 4d that interlocks with the carrier 8a. Next, the square 3a of the weighing device 3 is rotated by a predetermined number of revolutions based on the rice cooking amount set, and the weighed rice is thereby put into the rice washing container 4a via the chute 7. Thereafter, the lenoid valve 5c is opened and water is supplied into the rice washing container 4a, and at the same time the stirring rod 4b is rotated to wash the rice. At this time, the bottom opening of the rice washing container 4a and the bottom plate 4d are not completely sealed, so that some water may leak out. As a result, the washed rice is drained out of the main body 1 through the entire conveyor 8a and through the drainage receiver 9. Such rice washing is repeated until the sewage turbidity becomes less than a predetermined value or a predetermined time elapses, and after the final rice washing, the solenoid nozzle 5C is closed and the operation is stopped until all drainage is completed. After that, the carrier 8at
- Swing the left end 8c downward and open the bottom opening of the rice washing container 4a. Then, the solenoid knob 5c is opened for a predetermined period of time to supply water to the rice washing container 4a, and while washing off the rice adhering to the container 4a and the conveyor 8a, the rice and the corresponding amount of rice are added to the pot of the rice cooker 10. of water. Incidentally, at this time, a watering tool may be attached to the tip of the water supply pipe 5b in order to completely wash off the rice adhering to the rice washing container 4a and the like. Next, the carrier 8a is again swung to the drainage side, and water is supplied for a predetermined period of time to perform post-cleaning. The position of the carrier 8a is detected by limit switches 18a, 18b and accurately controlled by the control device 6. Differential holding device 12 at the same time as post-cleaning
energize the electromagnet 15 to attract one end of the plate 13b,
Unlatch the lid 11. As a result, the lid 11 falls due to its own weight. At this time, the lid 11 cannot be completely closed because of the latch mechanism or because the impact is absorbed by a shock absorber (not shown). Here, the motor 21 rotates, the arm 23 rotates and presses the lid 11,
Close the lid 11 completely. At this time, a constant current flows through the motor 21 until the arm 23 presses the lid 11t, but when the arm 23 begins to press the lid 11, the repulsive force of the lid 11 increases the stain flow, and further When the lid 11 is completely closed, it tries to rotate against the elasticity of the mounting member 25, so 1! The current increases further until the motor 21 locks up and the current becomes constant. Therefore, the lid 11
A reference is set to a current value slightly larger than the current value when the lid 11 is closed, and when the current value of the motor 21 exceeds this reference, it is determined that the lid 11 is closed. This judgment is made by the control device 6 consisting of a microcomputer, and when this judgment is made, the control device 6 reverses the motor 21 and rotates the arm 21.
3 to the limit switch 24 position. At this point, the limit switch 24 is activated to stop the motor 21 and proceed to the next step. Further, if the lid closure detection is not performed even after a predetermined period of time has elapsed from the start of operation of the motor 21 due to a failure of the motor 21 or the like, an alarm is issued to notify the user. - 10,000, the rice in the pot is in a heaped state, and in reality, the rice cooker 10 is given horizontal vibration by a vibration table installed at the bottom of the rice cooker 10, and the rice is moved into the pot. Arrange evenly. Thereafter, a standby time is allowed to soak the rice in water for a predetermined time, and then energy is applied to the rice cooker 10.

The above is the case when the rice cooking switch 19b is selected, but when the rice measuring switch 19a is selected, the conveyor 8a is swung toward the rice cooker 10 from the beginning, and the rice is weighed as described above. The washed rice passes through the rice washing container 4a and is stored in the pot of the rice cooker 10 via the carrier 8a, and the lid 11 is closed.

Also, when the rice washing switch 19c is pressed, the rice cooker 10
The step 1 before inputting rice cooking energy to the rice cooker is performed in the same manner as when the rice cooking switch 19b is selected. This is used, for example, when making takikomi rice.

The conventional device described above detects that the lid 11 is completely closed and moves on to the next process, and the lid 11 is opened! There is no need to input energy into the rice cooker 10 and cause rice cooking to fail. Furthermore, when the motor 21 is locked, it rotates in reverse and stops, so damage to the motor 21 can be prevented.

[Problems to be Solved by the Invention] However, in the conventional device described above, in order to completely close the lid 11 of the rice cooker 10 that has fallen due to its own weight, the motor 21 is
This requires a special lid closing device 20 consisting of an arm 23 and an arm 23, resulting in a complicated and expensive structure.
