A spring force is applied to open the free end of the carrier 16.
is in contact with the conveyor path so as to press it. Therefore,
The protruding end of the bottom plate 23d similarly moves up and down in accordance with the vertical movement of the end in the same direction (the left end 16a in FIG. 1) of the conveyor 16, that is, the scene movement of the conveyor 16, and the rice washing container 23a Open and close the bottom opening. A motor (not shown) for swinging the carrier 16 and a motor 23c for rotating the stirring plate 23b are both electrically connected to the control device 25.

A water supply device 24 is installed above the rice washing device 23, and the water supply device 24 is connected to a water receiving tank 24 connected to an appropriate water source.
a, a water supply pipe 24b having one end connected to the bottom of the water receiving tank 24a and the other end facing the upper opening of the rice washing container 23a; and a water supply pipe 24b provided in the water supply pipe 24b to control the amount of water flowing through the pipe. The solenoid pulp 24c is composed of a solenoid pulp 24c. This solenoid pulp 24c is electrically connected to a control device 25, and its opening time is controlled.

At the lowest part of the apparatus main body 11, there is a drainage receiver for draining water that flows down from the right end 16b of the transport body 16 of the transport device 15 when the transport body 16 of the transport device 15 swings with its right end 16b facing down. 17 are arranged. In addition, the carrier 16
When the rice cooker 1 is swung so that its left end 16a is facing down, the rice cooker 1 is placed in a position where the water and rice flowing down from the left end 16a are collected.
2 is placed.

In this position, the lid 13 of the rice cooker 12 is opened so that the rice and water that have fallen from the left end 16a of the carrier 16 can enter the inner pot. At that time, the rice cooker lid holding device 30 attached to a predetermined position in the main body 11 grasps the gripping flat part 13a formed on the top surface of the lid 13 and opens the lid 13 halfway, that is, the opening angle of the lid 13 is Hold it open within a range of 90 degrees or less.

Automatic rice preparation device 10 according to the embodiment configured as described above
The operations are performed sequentially by the control device 25 as shown in the flowchart of FIG.

That is, if there is no rice stored in the rice storage chamber 21, rice is first put into the storage chamber 21. Next, the lid 13 of the rice cooker 12 is press-fitted into the 814 holding device 30 and latched, and the rice cooking amount adjustment section and the rice cooking time adjustment section of the control device 25 are respectively set. Then, the user presses a selection switch to select which operation is to be performed by the automatic rice preparation device 10, and selects the operation. As the selection switches, a rice measuring switch 19a, a rice cooking switch 19b, and a rice washing switch 19c are attached to the control display board 19 on the upper part of the main body 11, and all of these are connected to the control device 25.

Now, if you select and press the rice cooking switch 19b, the control device 25 determines whether or not the lid 13 of the rice cooker 12 is open based on a signal from a limit switch (not shown).
If the limit switch is turned on, that is, if the rice cooker lid holding device 30 holds the lid 13, the rice cooker enters a standby state until the timer is set to start the operation. If the limit switch is off, an alarm buzzer or the like is immediately activated to notify the user of the incorrect setting immediately after the setting is completed.

When the operation start time set by the timer comes, the conveying body 16 of the conveying device 15 is swung toward the drainage side.

As a result, the bottom opening of the washed rice container 23a is closed by the bottom plate 23d. Next, the square 22a of the measuring device 22 is rotated by a predetermined number of revolutions based on the rice cooking amount set, and the set amount of rice is measured and dropped into the chute 14 and placed in the rice washing container 23al'lK. After that, the solenoid pulp 24c is opened and water is supplied into the rice washing container 23a.
At the same time, the stirring plate 23b is rotated to wash the rice. that time,
The sealing between the bottom opening of the rice washing container 23a and the bottom plate 23d is not made perfect, but only to the extent that some water leaks from the closed part. As a result, the washed rice water leaks out from the closed part, passes through the conveyor 16, and is drained into the drainage receiving part 17. Such rice washing is carried out repeatedly by detecting the turbidity of the sewage water or by observing the lapse of time determined experimentally. After the final rice washing, the solenoid pulp 24c is closed, and the drainer, that is, the container 23a, is closed.
All operations will be stopped until the water inside is completely drained.

Thereafter, the drive device of the conveyance device 15 is activated and the conveyance body 1
6. The rice washing container 2 swings and the left end 16a tilts downward.
The bottom plate 23d of the bottom opening of the rice washing container 23a is opened, and a passage through which the rice in the rice washing container 23a is poured into the pot of the rice cooker 12 is secured. However, the wet rice adheres to the inner wall of the rice washing container 23a,
Alternatively, even if most of the rice falls onto the conveyor 16, it will hardly naturally flow down into the rice cooker 12 because it will adhere to the wall of the conveyor. Therefore, next, in order to supply water to the rice cooker 12 according to the amount of rice, the solenoid pulp 24c is opened for a predetermined period of time, and the necessary amount of water is supplied into the rice washing container 23a. As a result, rice adhering to the rice washing container 23a and the conveyor 16 is washed away and the rice cooker 12 is washed away.
It is placed in a pot.

At this time, a watering tool may be attached to the tip of the water supply pipe 24b in order to completely wash off the rice adhering to the rice washing container 23a and the like.

Next, in order to wash the rice washing container B23a and the carrier 16, the carrier 16 is swung toward the drainage side, and water is supplied again for a predetermined period of time. Whether or not the position of the transport body 16 is accurate for the operation of this device depends on each end 16a,
The control device 25 receives signals from the limit switches 18a and 18b, which are arranged to come into contact when the limit switch 16b is positioned downward, and makes a decision, and as the case may be, operates a drive device to correct the position.

At the same time as the washing operation of the rice washing container 23a, the rice cooker lid holding device 3
The electromagnet 0 (not shown) is activated, thereby releasing the grip of the flat portion 13a of the lid 13 by the holding device 30, and the lid 13 falls under its own weight and closes. However, among the rice and water dropped into the rice cooker 120 pot, the rice rises up like a mountain at the position where it fell.
Not evenly scattered in the pot. Therefore, the rice cooker 12 is placed on a suitable vibrating table placed at the inner bottom of the main body 11, and horizontal vibration is applied to a rocking device (not shown) to disperse the water in the pot. preferable. Thereafter, a standby time is required to soak the rice in water for a predetermined period of time, and then the power to the rice cooker 12 is turned on, or the burner is ignited if it is a gas rice cooker.

Next, when the rice measuring switch 19a is pressed, the measured rice passes through the rice washing container 23a and is directly supplied into the pot of the rice cooker 12, and the lid 13 is closed, and this operation ends here. .

Furthermore, when the rice washing switch 19c is pressed, the rice is weighed, washed, and a predetermined amount of water is supplied into the pot of the rice cooker 12, the rice is prepared, and the lid of the rice cooker 12 is closed. finish.

Such an operation is used, for example, when making stir-fried rice. The series of operations described above is performed by the control device 25.
This can be easily done using a microcomputer or the like.

(Effects of the Invention) As explained above, according to the automatic rice preparation device of the present invention, water corresponding to the washed rice is supplied together with the washed rice, so the mechanism for adjusting the amount of rice cooking water is different from that of the conventional one. This method is extremely simple compared to the previous method, and since the washed rice is put into the pot of the rice cooker after sufficient time has elapsed for draining after washing, some of the water from washing the rice is drained into the pot. It is possible to adjust the amount of cooking water very accurately since there is no grain entering the rice cooker.
