→ Steam (purple) (t9) → Replace inner pot 7 after cooking rice (t)
Through each process of 10).

The rice washer 2 moves to the left L and the right R independently,
In a mode in which rice is washed while switching and supplying rice to the two rice cookers 3 and 4 on the left and right sides, each immersion step t3 to t7 is set to an appropriate time by the setting switch 62 as the immersion time, so that each rice washing step T1 = By making t1 to t6 and the rice cooking process T2 = t7 to t10 in each rice cooker 3 continuous, it is possible to perform an efficient operation of the entire rice washing → rice cooking process T = T1 + T2. The time that changes in each process
The immersion process t3 to t7 and the steaming process t9,
The ratio between the rice washing section immersion t3 and the kettle immersion t7 may be changed. The setting of the immersion time by the setting switch 62 may be made by changing and setting either one of t3 or t7, or both t3 and t7. The immersion time is calculated by the controller CPU as t3 + t7, and the rice immersion time after washing rice t7 is calculated and controlled. The water adjustment t5 is adjusted so that the immersion time matches this set value.
The start of the water adjustment t5 is started by the outputs of the solenoid valves 29 and 30.
By detecting the end of the rice cooking process T2, the rice cleaning process is performed after the rice washer 2 has moved onto the rice cooker 3 or 4.

That is, the rice cookers 3 and 4 have an inner pot sensor 73 for detecting that an empty inner pot 7 is provided, a lid sensor 74 for detecting the presence of the pot lid 8 on the inner pot 7, After the rice washing, the rice washing machine 2 is moved to the left or right side to detect that the rice washing machine 2 has stopped and the rice washing machine 2 is stopped. The water adjustment t5 in the vessel 2 is started.
When the water adjustment t5 is completed, the discharge valve 21 is opened by the output of the discharge motor M3, and the washed rice is dropped into the rice cooker 3 or 4 together with the water adjustment t6, and the rice is immersed in the kettle for the calculated time. Is performed.

When the rice washing is completed early and the rice cooking is delayed, the movement t4 is started with the rice washing section 2 immersed in the rice washing section 2 and the drainage drainage in the rice washing section 2 performed. Wait for. At this time, the rice washes in the rice washer 2 are on standby without being subjected to the immersion action.

The main part of the figure will be described in detail below. (About weighing operation by weighing switch) When the weighing switch 51 is turned on, the weighing motor M1 is driven by the output from the controller CPU, and the weighing cylinder 77 is operated.
Is rotated integrally with the shaft 16 and the cam 78 (FIG. 7).
~ FIG. 12). By turning on and off the rotation sensor 17 composed of a pulse switch (limit switch) at the position where the cam 78 has made one rotation, the metering motor M1 is stopped and brought into an initial state. In addition, ON, O of this rotation sensor 17
By counting the input of the FF signal by the controller CPU, the number of rotations of the metering motor M1 and the amount of feed from the rice tank 1 to the rice washing machine 2 are calculated.

The weighing switch 51 is pressed for abnormality processing or inspection. When the weighing switch 51 is turned on, the weighing motor M1 returns to an initial state in which the weighing cylinder 77 is driven by one rotation. 17 ON / OFF
The metering motor 15 is driven by the measuring cylinder 77 even if the metering switch 51 is pressed again to stop the operation until the rotation sensor 17 is completely turned on and off.
You cannot stop on the way until one complete rotation.

As described above, when the weighing switch 51 is pressed to drive the weighing motor M1, the weighing motor M1 is always stopped in the initial state, so that the weighing operation is not affected. This is because if the weighing motor M1 is stopped at an intermediate position during abnormal processing, inspection, or the like, accurate weighing cannot be performed when the rice washing operation in the original operation of washing and cooking rice is started. (About rice washing method) By operating the washing method switch 61, five steps are set from when the rice is lightly washed to when the rice is carefully washed, and which washing mode is set in advance when washing the rice. . When one of the five washing methods is selected by the washing method switch 61, the rice washing motor M2, the solenoid valve 30 for upper water supply, the solenoid valve 29 for lower water supply,
In addition, the rice washing control is performed by outputting the solenoid 32 of the drain valve 26 and the like.

In each of the five modes of the washing method, the control output includes a rice washing time, an upper water supply time, a lower water supply time, a drainage time, and the like.
The number of repetitions of the rice washing and the like and the time of the whole rice washing process (FIGS. 13 and 14) are changed and set for each process such as bran removal, polished rice, rough rinsing, finishing rinsing by overflow, etc. The mode is set in five stages from the mode of performing to the mode of performing carefully, and stored in memory.

Further, in such a rice washing method, a communication port 79 of the controller CPU may be provided so that data can be set in the RAM of the controller CPU so that it can be freely set.

In the "bran removal" of each step, the bran remaining in the rice is quickly washed away. The “polished rice” grinds rice while flowing water from above with the drain valve 26 opened. "Rough rinsing" operates the rice washing motor M2, and repeats water supply and drainage to rinse rice. In the “finish rinse”, the operation time of the rice washing motor M2 is made as short as possible, and water is repeatedly supplied and drained to rinse rice. (Regarding the check control of water supply) In the embodiment without the water supply switch 53 and the sewage switch 54, the rice washing in the rice washing machine 2 is performed by the solenoid valve 3 for water supply.
Even if the operation is performed by opening the solenoid valve 29 or the like for lower water supply, even if these solenoid valves 30 and 29 are opened, when water supply is impossible, rice cannot be washed. In such a case, the metering supply of the rice from the rice tank 1 is not performed.

That is, before the measurement by the measuring device 15 is started, the solenoid valves 30 and 29 for water supply are opened and the drain valve 26 is closed. The time until the water upper limit sensor 37 is turned on by the water supply in the rice washing machine 2 is checked by the monitoring timer T4 to monitor the abnormality of the water supply system. If there is any abnormality at this time, the rice is not weighed and the operation is stopped and the abnormality is processed. If there is no abnormality, the metering and feeding of the rice is performed, and the rice is supplied into the supplied rice washing machine 2. When the drain valve 26 is opened, the rice bran is washed away (FIG. 1).
5, FIG. 16) At this time, the stirring rod 19 may be driven. (Regarding the operation of the release switch 58) The opening / closing mechanism of the discharge valve 21 will be described in detail with reference to FIGS. 21 and 22. The timing cam for turning ON / OFF the discharge valve close sensor 81 on a shaft 83 driven by the discharge motor M3. 84 and an opening / closing cam 85 for opening / closing the discharge valve 21 are provided so as to rotate integrally. The opening / closing cam 85 pushes up a protruding roller 86 at the upper end of the valve shaft 23 to close the discharge port 22. The discharge port 22 is opened by removing the projection roller 86 from the opening / closing cam 85 and dropping it by its own weight. The timing cam 84 has a notch 87 formed in a part of the periphery thereof. When the notch 87 contacts the discharge valve closing sensor 81, the timing cam 84
FF is performed to stop the drive of the discharge motor M3.

A discharge valve opening sensor 82 is provided in the lower moving zone of the protruding roller 88 at the upper end of the valve shaft 23, and is turned on by the lower moving contact of the protruding roller 88 to open the discharging port 22. It is configured to detect that it has been dropped.

Referring to FIG. 17 and FIG.
8, the discharge motor M3 is rotated by the output from the controller CPU, and the discharge valve open sensor 82
After N, when the discharge valve closing sensor 81 is turned off, the discharge motor M3 is stopped.

The function of the drop switch 58 has the following two functions. When there is no rice in the rice washing machine 2, the rice washing machine 2 has a function as a mere inspection switch, so that an abnormality in the discharge motor M3 or the discharge valve 21 can be confirmed. When there is an upper and lower water supply solenoid valve 3 only by the drop switch 58
0, 29, water level valve 80, rice washing motor M2, and drain valve 2
1 and the like can be automatically driven to perform the remaining rice processing (FIGS. 17 to 19).

That is, in the drop test when there is no rice in the rice washer 2, when the drop switch 58 is pressed, the discharge valve 21 is opened, and then closed and stopped. If the drop switch 58 is pressed again during the continuous operation, the operation is immediately stopped. That is, every time the release switch 58 is pressed, the operation is repeatedly performed in ON and OFF, and stops when the closing is completed.

When there is remaining rice in the rice washing machine 2, when the drop switch 58 is pressed, the drain valve 26 and the water level valve 80 are closed, and
Open the lower water supply solenoid valves 30 and 29 and set the rice washer 2
Water. Next, the rice washing motor M2 is driven to execute a standard dropping step, a washing step, and the like, and the processing is terminated.

The discharge valve closing sensor 81 is connected to the discharge valve 21.
Is a limit switch that is driven by the discharge motor M3 to detect and raise the closed position, and that is turned on. The feedback control is performed so that the output of the discharge motor M2 is stopped when the discharge valve close sensor 81 is turned off.
The discharge valve open sensor 82 detects that the discharge valve 21 has been opened, and includes a limit switch. The discharge valve 2 is turned on by the ON and OFF signals of these two sensors 81 and 82.
Checking the operation of 1 and if there is an error, the error lamp 71 is turned on and the buzzer 72 is sounded.

When the release switch 58 is pressed for abnormality processing or inspection, the discharge motor M3 is driven, and the discharge valve 2
1 is opened and the washed rice is discharged and dropped, then closed and stopped in the initial state. The discharging motor M3 is prevented from stopping during the discharging, and at this time, a function of resetting the rice washing process is also provided.

If the discharge motor M3 is stopped halfway,
When you start washing rice, rice and water are still flowing down,
Since the normal operation stops, the release switch 58
Then, the discharge valve 58 is initialized to a closed state and stopped.
In addition, since the rice washing process is reset by the drop switch 58, when it is not clear what kind of operation relationship it is due to abnormal processing or the like, the rice washing is restarted by initialization by the drop switch 58. Easier to do. (Relationship between the metering switch 51 and the drop switch 58) When the rice is supplied to the rice washing machine 2 by the metering switch 51, the rice washing is not started, and the discharge valve 21 is opened by the drop switch 58. Then, even if there is residual rice in the rice washing machine 2, the rice is discharged, the abnormal flag is reset, the rice washing machine 2 is emptied, and rice washing can be started (FIGS. 23 and 24).

For this reason, when rice is dropped into the rice washing machine 2 by turning on the measuring switch 51, the rice washing cannot be started, so that the measuring section can be inspected with confidence. Further, even if the start switch 67 of the rice washing control is pressed and turned on by mistake, this is not accepted, and the failure of the rice washing operation is eliminated. When the weighing switch 51 is turned on, the drop switch 58 is turned on,
Since the remaining rice is processed and the abnormality flag is reset, the next rice washing operation can be reliably started. (Regarding scheduled pot number control)
25 (1) and (2), the expected number of hooks is set in advance by the hook number setting switch 66, and the start switch 67 is turned on to start the work. The set number of kettles is reduced and displayed by the washing and cooking work.
When it becomes 0 as shown in FIG. 25- (3), rice washing and cooking are automatically stopped. In addition, the worker starts rice washing even if the start is performed without setting the number of pots, so that the number of pots can be corrected later. However, if the start switch 67 is turned ON without setting the number of hooks,
It is necessary that the display unit 9 is a display other than 0.
When the number of hooks is 0, the number of hooks other than 0 is set and restarted as shown in FIG. 25- (4). Thereby, the rice washing is normally started according to the setting of the planned number of pots (FIG. 26).
Since the operation can be started only by operating the start switch 67 (FIG. 27), the operability can be improved.
When the estimated number of shuttles 49 is 0, the cause of the erroneous operation or the inability to start is clarified by clearly indicating that the start is impossible. (Regarding Display Control of Remaining Time of Rice Washing and Cooking) As described above, in the operation panel 40 (FIG. 28), as the process display 50, a rice washing display 89 at the top is provided for rice replenishment, rice washing, and immersion (rice washing machine immersion). The process is indicated by LED lighting. At the bottom, rice cooker display sections 90 and 91 corresponding to the left and right cookers 3 and 4 are displayed by turning on the LEDs as the steps of cooking, soaking, igniting, cooking, and completing cooking. In the rice washing display section 89 and the rice cooking display sections 90 and 91, remaining time display lamps 92, 93 and 94 for displaying the remaining time (minute display) by LED lighting are arranged, and as shown in FIG. By the display circuit 95 from
The display is turned on as shown in FIG.

Therefore, the current travel position and the remaining time until the completion of the rice washing or the rice cooking are displayed. (Regarding the help switch) When the help switch 70 is pressed and turned off, an error code is displayed on the display unit 41. When the help switch 70 is turned on, the page number of the instruction manual is displayed as a help number (FIGS. 31 and 31). In the case of abnormal operation, usually, an abnormal code is output from the LED and the operation is immediately stopped. However, at this time, it is difficult for the operator to understand the meaning only by looking at the abnormal code. Therefore, by being able to display the help number (the number of pages of the instruction manual),
Coping can be done promptly. This help switch 70 is displayed only while being pressed.

FIG. 33 shows the help control process for an abnormal condition in the entire control process of the rice washing and rice cooking control, and FIG. 34 shows the help process control of the help process. The help display includes a help process during an abnormal process (help codes 11 to 39), a help process for an erroneous manual operation (help codes 51 to 57), a help process for a prompt (help codes 61 to 65), and a normal operation state. Is notified in four blocks of the help process (help codes 71 to 86) in the above, and the notification is made by changing the combination of the LED and the buzzer sound, the time, the state, and the like. When a plurality of help code flags overlap, priority is displayed from high to low in the order of the above blocks, and the help processing during the abnormal processing is given the highest priority.
