When the button is pressed, a reservation process is started. When a predetermined set time is reached, the process proceeds to the weighing process. When the reservation button 38 is not operated, the process immediately proceeds to the weighing process, and weighing is performed as set. In the measuring step, a predetermined amount of rice is discharged from the rice storage tank 7 to the rice washing tank 15 via the measuring unit 8 in accordance with the selected rice cooking amount. In the measuring section 8, the amount of the discharged rice is stored and integrated.

The stored and integrated amount of cooked rice is displayed on the total cooked rice display section 43B described above for a certain period (FIG. 1).
It is displayed as a value of the amount of cooked rice for each day (0 indicates one week) and a value of the total amount of cooked rice for a predetermined period. When the weighing process is completed, the process proceeds to rice washing, polishing rice, and overflow processes. In the rice washing process, a predetermined amount of water is sprinkled from the shower supply pipe 21,
Stir the rice in the rice washing tank 15 with the stirring means 18,
This is the washing process. At this time, the on-off valve of the drainage device 23 is open and drained.

The rice polishing step is a step in which the water supply is stopped and the stirring means 18 is rotated. In the overflow process, the on-off valve of the drainage device 23 is closed, and rice is stirred by the stirring means 18 while water is supplied from the shower supply pipe 21 to the rice washing tank 15.
This is a step of draining water from the overflow drain pipe 23A, and finally opening the on-off valve of the drainage device 23 to drain all the water in the rice washing tank 15. The rice washing and polishing steps are performed a plurality of times, and the overflow step is performed once at the end.
These steps depend on the selection of the washing method, and are controlled by 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 mode is the rice washing mode. That is, the “wash rice” is selected by the selection button 40.
If is not selected, the process proceeds to a zircon raising process. The shrinking step is a step of holding rice for a predetermined period of time in the rice washing tank 15 with water removed. The holding time is the time set by the timer set button. The remaining time during the waiting for the zara raise is displayed on the character display section. When "Cooking preparation" is selected by the selection button 40 in the setting character display section 33, the process is once performed in the middle of this raising process, and replace the empty inner pot as shown in FIG. Message is displayed and the process does not proceed to the next shutter opening process.

When the "automatic rice cooking" mode is selected, the process automatically proceeds to the next shutter opening step. When the mode is “rice washing”, the zirzag step is skipped and the process proceeds to a shutter opening step. The shutter opening step is a step of opening the shutter 30 to open the opening of the lid 28. When the shutter 30 is opened, the process proceeds to the next water adjusting process.

The water adding / decreasing step is a step in which the controlled amount of water selected by the selection button 40 is supplied from the shower supply pipe 21 to the rice washing tank 15. Next, the process proceeds to a valve opening process.
In this step, the rice discharging valve 16 of the rice discharging section is opened, and the rice washing tank 15 is opened.
This is a step of discharging rice and water in the inner pot 27 of the rice cooking section 6. Then, in the next valve closing step, the rice discharging valve 16 is closed, and in the next shutter closing step, the shutter 30 seals the opening of the lid 28. If the rice washing mode has been selected, the process ends.

If the mode is not the rice washing mode, that is, if it is the automatic rice cooking mode, the process proceeds to the rice washing completion step. This step is a step of sounding a guide buzzer or the like to notify the operator of the completion of rice washing. Then, the process proceeds to the dipping process. This step is a step of sounding a guide buzzer or the like after a predetermined time has elapsed to notify the operator. When automatic rice cooking is set, rice cooking is started by the signal of automatic ignition, the rice cooking process, the rice drying process, the cooking are finished, and the display is finished, and a message of “Please take out the rice” is displayed on the display unit 34.

On the other hand, when the manual ignition is set, the character display portion 34A shown in FIG. 5 is displayed, and a message of the manual ignition (in FIG. 5, a message of "Please turn on the rice cooker") is issued. Then, thereafter, the process proceeds to the rice cooking process, the steaming process, and the cooking process, and all the processes are completed. The present invention is not limited to the above embodiment, and can be appropriately designed and changed. For example, the total cooked rice display section 43B described in the above embodiment shown in FIG. 10 displays only the amount of cooked rice per day for a certain period, and does not display the amount of cooked rice per day before a certain period. However, the amount of cooked rice for each day in a specific period is stored, and the select button 40 or the like is operated to call up and display the amount of cooked rice for each day prior to a certain period and a display indicating the day.
