Regarding the gas ignition for the rice cooking process in the rice cooker 2, as shown in the flow chart of FIG.
First, it is checked whether or not the time for the kettle soaking process has ended, and if YES, the process proceeds to the next step, and it is checked if the ignition changeover switch 4 is switched to the manual ignition position. If YES, Proceeding to the next step, an ignition request is signaled by, for example, a warning sound made by a buzzer or the like and blinking of the indicator lamp 3a for displaying ON of the ignition switch 3. Upon receipt of this signal, the operator checks whether or not the ignition switch 3 has been turned on. If the answer is YES, the process proceeds to the next step, in which the rice cooker 2 is gas-ignited to start rice cooking and at the same time, the rice cooking process is performed. When this check is NO, the process returns to the ignition request stage again. Further, when the check of the manual ignition position by switching the ignition changeover switch 4 in the previous stage is NO, since it is the automatic ignition position, gas ignition is automatically performed to start rice cooking and to perform rice cooking processing. Further, if the check of the time end of the previous pot dipping process is NO, it is checked whether or not the ignition switch 3 is turned ON by the operator, and if YES, the pot dipping is performed by the action of the forced ignition means 5. Nonetheless, the gas is ignited unconditionally to start the rice cooking and at the same time the rice cooking process is performed. When this check is NO, the process returns to the first stage.

As described above, when rushing to cook rice, the ignition switch 3 can be turned on and the rice cooker 2 can be forcibly ignited without waiting for the completion of the pot soaking process by the forced ignition means 5. The rice cooking time can be shortened and efficient operation can be performed. In this case, since the time for the pot dipping process is flexible, rice can be cooked even if the dipping time is shortened, and it can surpass the emergency.

In addition, in order to set the reserved date and time when the rice cooking process is automatically operated by reservation, the timer reservation switch 7
When 8 is turned on, the time setting switch 79 for setting while displaying the reserved time in the time display window 9 and the day indicator 1
It has a day setting switch 80 for setting while displaying the reserved day at 0, and when the reserved time is a number smaller than the current time, the reservation timer of the rice rinsing rice cooker automatically carries over the day to the next day.

With this configuration, as shown in the flow chart of FIG. 8, it is first checked whether or not the timer reservation switch 78 is turned on. If YES, the process proceeds to the next stage, and if NO, the process returns to the first stage. When moving to the next step by YES, check whether the reserved time number is less than the current time number, proceed to the next step if YES, calculate the rice washing start time from the time check process if NO Go to. In the shift to the next step by YES, it is checked whether the reserved day and the current day are the same day, the YES step proceeds to the next step, and the NO step proceeds to the calculation of the rice washing start time. In the case of shifting to the next step by YES, the reserved day of the week is carried forward to the next day, the rice washing start time in the next step is calculated, and the reservation is confirmed in the final step.

In this way, the current time at the time of reservation and the reservation time are, for example, as shown in FIG.
If you want to set the reserved time to 07:00 on Tuesdays, as opposed to 0:30, the reserved time is numerically smaller than the current time, so you only need to set the reserved time and set the day indicator 10 to Monday. Can be automatically set to the next Tuesday. For this reason, when it is necessary to carry over the day of the week at the time of reservation to the next day, it is not necessary to bother to operate the day-of-the-week setting switch 80, and it is possible to prevent a malfunction due to forgetting the correction. This reservation time is stored in the controller 6, so when making a reservation at a fixed time every day,
It is only necessary to turn on the timer reservation switch 78, and it is not necessary to set the time and day of the week again.

Further, in order to check the malfunction of all the switches provided on the panel 6a of the controller 6 and the circuits thereof, a code for performing the check is given to all the switches arranged on the panel 6a of the controller 6. The switch inspection device of the rice cooker is configured to digitally display the allocation code on the time display window 9 by turning on each switch in the test mode in which the allocation and test switch 52 are turned on.

With this configuration, as shown in the flowchart of FIG. 10, it is first checked whether the test mode is the test mode by turning on the test switch 52. If YES, the process proceeds to the next stage, and if NO, the final stage. move on. YE
In the transition to the next stage by S, all the indicator lamps arranged on the panel 6a are turned on all at once to perform a lighting check. In the shift to the next stage after the completion of this inspection, all the switches arranged on the panel 6a are sequentially turned on, and it is checked whether or not each switch is turned on. If YES, the process proceeds to the next stage, and if NO. At that time, the process proceeds to the check stage in the test mode. In the shift to the next step by YES, as shown in FIG. 11, the inspection numbers assigned to all the switches are digitally displayed on the time display window 9 in correspondence with the ON of each switch, and depending on whether the displayed contents are correct or incorrect. Check the working status of each switch and its circuit. In the transition to the next stage after the completion of this inspection, it is checked again whether or not it is the test mode. If YES, the process returns to the stage of inspecting the indicator light again, and if NO, the inspection is finished.

As described above, in the test mode, by displaying the inspection number assigned to each switch on the time display window 9 for each switch ON, ON / OFF of each switch, short circuit between each switch, etc. Since it is possible to inspect and confirm the defect state due to, for example, the inspection number of the day setting switch 80 is displayed as 24, and the changeover switch 81 is displayed.
When the inspection number of 24 is also displayed, it is possible to easily confirm that the changeover switch 81 has a problem due to a short circuit of the foil on the substrate. (The original inspection number of the changeover switch 81 is 25)
