Next, FIG. 9 (1) shows the operation of the automatic rice cooker having the above configuration.
(2) A description will be given according to the flowcharts of (3).

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 simultaneously pressing a plurality of buttons on the operation panel 60. In the case of “test”, the process proceeds to the test processing step and various tests are performed.

If it is not "test", the process proceeds to "initial processing" and "maintenance processing" steps. The step of "initial processing" is to set each device to an initial state, and is a step used at the initial stage of use. "Maintenance processing"
"Tank remaining rice treatment" or "Water supply" switch 77a, 77b
This is the step that operates when you press. In normal use, the above steps are bypassed.

The operator then presses either the "reserve" switch 61 or the "immediate" switch 62. "Reservation" is used when operating at a predetermined time, and "immediate" is used when operating from the current time.

When any of the switches is pressed, the process proceeds to a “water amount check” step.

In this water volume confirmation step, the shower solenoid valve 25
Is opened, water is supplied to the rice washing tank 16, the remaining rice treatment in the tank 16 is performed, 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. The flow rate is stored.

Next, the operator makes a menu selection. This menu selection is made by pressing the setting switches 72-75 for "rice cooking amount", "hardness", "how to wash", and "mode".
These time settings are made by operating 76a and 76b. When the menu set in advance or the previous time is adopted, no menu selection is performed.

Next, the operator sets the time. With this time set, the "time setting" switch 78 is used to correctly display the current time or set a reserved time. If you want to use the current settings, you don't need to set them.

The operator then presses the "start" switch 63.
When the "reservation" switch 61 is pressed, the reservation process starts, and when the predetermined set time comes, the process advances to the weighing process.

When the "reserve" switch 61 is not operated, that is,
When the "immediate" switch 62 is pressed, the "start" switch 63 is pressed to immediately proceed to the weighing process.

In the weighing process, a predetermined amount of rice is washed from the rice storage 9 through the weighing unit 4 according to the set amount of cooked rice, and then washed in the rice washing tank 16
Is discharged to. In the weighing unit 4, the amount of discharged rice is stored, integrated, and the rice cooking amount display unit 65 can display the starting rice cooking amount (total amount in a predetermined period such as one day or one week).

After the weighing process, proceed to washing, polishing, and overflowing.

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

The rice polishing process is a process of stopping the water supply and rotating the stirring means 17.

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

The washing process and the polishing process are performed multiple times, and the overflow process is performed once at the end. These steps are influenced by the setting of the "washing method" setting switch 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 washing mode. That is, the "mode" setting switch 75 is used to "wash rice".
If is not set, the process proceeds to the straining process.

The straining step is a step of holding the rice in the rice washing tank 16 for a predetermined time while the water is drained. The holding time is the time set by the timer set button 76. The display unit 68 displays the remaining time during the waiting for raising the strainer.

When "Preparing rice" is set with the "Mode" setting switch 75, the process is temporarily stopped in this straining process and unless the operator presses the water addition start switch 67.
The next shutter opening process does not proceed.

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

When the mode is “washed rice”, the colander lifting process is skipped and the shutter opening process is performed.

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

 When the shutter 47 opens, the process goes to the next water addition / decrease process.

The water addition / reduction process is a process in which the amount of water controlled by the setting of the “hardness” setting switch 73 is supplied from the shower water supply pipe 22 to the rice washing tank 16. At this time, the open / close valve 30 is closed.

Next, the valve opening process is performed. This process is the rice removal valve of the rice removal unit 6.
Open 34 and put the rice and water in the washing rice tank 16 into the inner pot of the rice cooking section 7.
It is the process of discharging to 55.

The rice discharging valve 34 is closed in the next valve closing step, and the shutter 47 closes the opening 46 of the lid 45 in the next shutter closing step.

If the rice washing mode has been set, the process ends.

If it is not the rice washing mode, that is, if it is the rice cooking automatic 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, proceed to the dipping process. This step is a step of notifying the operator by sounding a guide buzzer or the like after a lapse of a predetermined time.

Next, the process of waiting for input of the rice cooking lever is started, and the ignition of the ignition lever 56 is awaited. When the operator operates the ignition lever 56 to ignite the gas, the rice cooking process, the steaming process, and the cooking process are performed thereafter, and all the processes are completed.

It should be noted that the switches and functions operated simultaneously are not limited to those in the above-described embodiment, and other combinations of a switch covered by the closed posture of the cover 80 and a switch covered by the open posture of the cover 80 may be used. It may have the function of. Further, the switches located at the bottom of the display panel 86 are arranged on the left and right sides of the display panel 86, and the switches located at the upper part of the display panel 86 are arranged on the left and right sides of the display panel 86, respectively, and the cover 80 is provided. The layout of the switches and the direction of rotation of the cover 80 are free, such as being supported rotatably around the vertical axis in the middle of, and, in short, one of the two switches that are pressed simultaneously is in the closed position of the cover 80. It suffices if the other switch is disposed in the portion covered with the open position of the cover 80, respectively.

(Effect of the Invention) According to the present invention, one of the two switches that are simultaneously pressed is arranged in a portion covered by the closed posture of the cover of the display panel, and the other switch is opened of the cover of the display panel. Since it is placed in the part covered by the posture,
When one switch is being operated, the other switch is covered by the cover and is not pushed by contact or the like, and it is possible to prevent two switches that are simultaneously pushed from being pushed at the same time.
