If it is higher than 00 ° C., the process proceeds to step 402. This processing is necessary when the heating power is set to the rice cooking power in a state where the heating as a normal stove is performed.
This is because the notification is performed as it is in the processing of (1).
This notification is unnecessary notification, and in order to prevent this false notification, when the sensor temperature is higher than 100 ° C., it is determined that the heating power is accidentally set to the rice cooking power in a state of use as a normal stove. Then, heating as a normal stove is continued. On the other hand, when the temperature is lower than 100 ° C., there is a possibility that the rice is cooked. Therefore, the process proceeds to step 404 corresponding to step 203. The processing after step 404 is the same as steps 204, 205, and 206 in FIG. 6, and steps 405, 406, and 407 correspond to steps 204, 205, and 206, respectively.

FIG. 9 is a block diagram showing the configuration of the third embodiment, and FIG. 10 is a flowchart for explaining the operation. Hereinafter, parts different from those in FIGS. 7 and 8 will be particularly described. A heating state determination unit 501 is provided instead of the heating state determination unit 301, and the heating state determination unit 50 is provided.

5 is included. Regarding the operation, a step 603 is provided instead of the step 403, and the other processing is the same, and the steps 601 602 604 605 605
6, 607 are steps 401, 402, 4
04, 405, 406, and 407. Step 6
03 is a process for determining whether or not the elapsed time after ignition is within 180 seconds. Even by this processing, it can be determined whether or not the rice cooker power is accidentally set during heating as a normal stove. That is, if it is a heating power setting for rice cooking heating, the heating power setting is also performed immediately after normal ignition, whereas if it is accidentally set to rice heating power while heating as a normal stove This is because time has considerably elapsed since ignition, and it is unlikely that the time is within 180 seconds. As described above, it is possible to determine whether or not the cooking power has been set to the rice cooking power during heating as a normal stove, so that unnecessary false notification can be prevented.
