Although the rice cooking section 7 is exposed to the outside world, the measuring section 4
rice washing motor 18, drainage motor 31, rice discharging motor 38,
Devices such as various sensors are housed in a sealed portion at the top of the main body frame 1. Therefore, the steam generated in the rice cooking section 7 rarely enters the sealed part, but if it does, it is necessary to exhaust the steam and to cool the various devices.
An exhaust fan 82 is provided on the bottom plate 81 of the sealed part (
(See Figure 18).

83 is a main switch.

Next, the operation of the automatic rice cooking device having the above configuration will be explained according to the flowchart of FIG. 23.

First, when the operator turns on the main switch 83, the microcomputer device of the control unit 8 determines whether or not it is a "test".

This "test" is selected by pressing multiple buttons on the display panel 60 at the same time.

In the case of "test", the process proceeds to a test processing step, where various tests are performed.

If it is not a "test", the process proceeds to the "initial processing" and "maintenance processing" steps.The "initial processing" step sets each device to its initial state, and is a step used at the initial stage of use. "Maintenance processing" is
This step is activated when the maintenance button 77 is pressed.In normal use, the above steps are skipped.

Next, the operator selects the "Reservation" button 61 or the "Immediate"
"Reservation" by pressing any button 62 is used to activate at a predetermined time, and "immediate" is used to activate from the current time.

If any pushbutton is pressed, the process advances to the "Water Level Check" step.

This water! In the confirmation step, the shower solenoid valve 25
opens, water is supplied to the rice washing tank 16, and the tank 16
The remaining rice inside the tank is processed, and the flow rate is measured by the flow rate sensor 24, and it is confirmed whether or not there is a predetermined flow rate, and the flow rate is stored.

The operator then makes a menu selection. This menu selection is performed by pressing the selection buttons 72 to 75 for rice cooking amount, hardness, washing method, and mode, and these time settings are performed by operating the timer cent button 76 for colander and unevenness. be exposed. If no menu selection is made, the previously selected menu is adopted.

Next, the operator sets the time, using the time and reservation set button 78 to correctly display the current time and set a reservation time. If you want to use the current settings as they are, there is no need to set them.

Next, the operator presses the start button 63.

When the reservation button 61 is pressed, the reservation process starts, and when the predetermined set time comes, the process goes to the weighing process.

When the reservation button 61 is not operated, that is, when the immediate button 62 is pressed, the start button 63 is pressed to immediately proceed to the weighing process.

In the measuring process, a predetermined amount of rice is transferred from the rice storage 9 to the rice washing tank 16 via the measuring section 4 according to the selected amount of rice to be cooked.
is discharged. In the measuring section 4, the amount of rice that has been discharged is stored and integrated, and the total amount of cooked rice (the total amount for a predetermined period such as one day or one week) can be displayed on the rice cooking amount display section 65.

Once the weighing process is complete, the rice is washed, polished, and overflowed.

The rice washing process is a process in which the rice in the rice washing tank 16 is stirred and washed by the stirring means 17 while sprinkling a predetermined amount of water from the shower supply pipe 22. At this time, the on-off valve 30 is open and water is being drained.

The rice polishing process is a process in which the water supply is stopped and the stirring means 17 is rotated.

In the overflow process, the on-off valve 30 is closed, and the shower supply pipe 22 and the overflow supply pipe 23 are connected to the rice washing tank 1.
6, the rice is stirred by the stirring means 17, water is drained from the overflow drain pipe 29, and finally the on-off valve 30
This is the process of opening the rice washing tank 16 and draining all the water in the rice washing tank 16.

The rice washing process and the rice polishing process are performed multiple times, and the overflow process is performed once at the end. These steps depend on the selection of the washing method selection button 74 and are controlled depending on whether a predetermined time has elapsed or a predetermined amount of water has been supplied.

When the above steps are completed, it is determined whether or not the rice washing mode is selected. That is, if "Rice washing" is not selected by the mode button 75, the process proceeds to the straining step.

The straining process is a process in which rice is held for a predetermined period of time in the rice washing tank 16 in a drained state.

The time to hold is the time set by the timer set button 76. The remaining time while waiting to raise the colander is displayed on the display section 68.

When "rice cooking preparation" is selected with the mode selection button 75, the process is temporarily interrupted at this strainer raising step and does not proceed to the next strainer opening step unless the operator presses the water level start button 67.

If the "automatic rice cooking" mode is selected, the process automatically advances to the next shutter opening process.

When the mode is "rice washing", the process of raising the rice in a colander is skipped and the process proceeds to the shutter opening process.

The shutter opening step is a step of opening the shutter 47 to open the opening 46 of the lid 45.

When the shutter 47 is opened, the process proceeds to the next water adjustment step.

In the water adjustment process, the amount of water controlled by the selection of the hardness selection button 73 is transferred from the shower supply pipe 22 to the rice washing tank 1.
6 is the process in which water is supplied to the tank.

Next, proceed to the valve opening step. This process is carried out by the rice discharging valve 3 of the rice discharging section 6.
4 is opened and the rice and water in the rice washing tank 16 are discharged into the inner pot 55 of the rice cooking section 7.

Then, in the next valve closing process, the rice discharging valve 34 is closed, and in the next shutter closing process, the shutter 47 seals the opening 46 of the lid 45.

If the rice washing mode is selected, the process ends with the above steps.

If you are not in rice washing mode, that is, if you are in automatic rice cooking mode,
Proceed to the rice washing completion process. This step is a step to notify the operator that the rice washing is complete by sounding a guide buzzer or the like. Then proceed to the soaking process.

This step is a step to notify the operator by sounding a guide buzzer or the like after a predetermined period of time has elapsed.

Next, the rice cooking lever enters a manual power waiting step and waits for the ignition lever 56 to ignite. When the operator operates the ignition reno ＼-56 to ignite the gas, the rice cooking process, steaming process,
Proceed with the cooking process and complete the entire process.

<Effects of the Invention> According to the present invention, the display panel 60 is provided with a graphic display section 71 depicting the overall shape of the rice cooker, and the graphic display section 71 has a display section 71 at a position corresponding to a process position and a check position, respectively. Lamp L! I+L! ! .
! Since the process position and the check position are displayed in the figure display section 71, the current process position and the position to be inspected can be shown in relation to the actual overall shape of the rice cooker. It is very convenient because it can be displayed in an easy-to-read manner, and therefore the process position and inspection position can be easily and concretely recognized. Moreover, the same display lamps t, z l + t of the graphic display section 71
