Has been done. Therefore, the steam generated in the rice cooker 7
Although it is unlikely that it will enter the sealed part, an exhaust fan 82 is provided on the bottom plate 81 of the sealed part in order to discharge steam if it should enter and to cool various equipment (see FIG. 18). . 83 is a main switch.

Next, the operation of the automatic rice cooker having the above configuration will be described with reference to the flowchart of FIG.

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 display 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"
Is a step that operates when the maintenance button 77 is pressed. In normal use, the above steps are bypassed.

The operator then clicks the "Reserve" button 61 or "Immediately"
Press any button 62. "Reservation" is used when operating at a predetermined time, and "immediate" is used when operating from the current time.

When any of the push buttons is pressed, the process goes to the "check water amount" 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 selection buttons 72-75 for the amount of cooked rice, hardness, washing method, and mode, and these time settings are made by operating the timer setting button 76 for raising the colander and the murmur. Be seen. If you do not select the menu,
The menu selected last time is adopted.

Next, the operator sets the time. In this time set, the current time is correctly displayed or the reserved time is selected using the time and reservation set button 78. If you want to use the current settings, you don't 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 a predetermined set time comes, the measurement process starts.

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

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 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, water is supplied from the shower supply pipe 22 and the overflow supply pipe 23 to the rice washing tank 16, the rice is stirred by the stirring means 17, drained from the overflow drain 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 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 washing mode. That is, when “washing rice” is not selected by the mode button 75, the process proceeds to the strainer raising 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 “preparation of rice” is selected by the mode selection button 75, the process is temporarily interrupted in this straining process and the next shutter opening process does not proceed unless the operator presses the water addition start button 67.

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 adjustment process is a process in which the amount of water controlled by the selection of the hardness selection button 73 is supplied from the shower supply pipe 22 to the rice washing tank 16.

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.

When the rice washing mode is selected, the above steps are completed.

If the mode is not the rice washing mode, that 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, the dipping process is performed next. 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 subsequently performed, and the previous process is completed.

<Effects of the Invention> According to the present invention, the display panel 60 is provided with the graphic display unit 71 depicting the entire shape of the rice cooker, and the graphic display unit 71 displays the graphic display unit 71 at positions corresponding to the process position and the check position, respectively.
