飯が炊けなくなり、好ましくない。In the above-described conventional electric rice cooker, rice grains and the like enter the hole 16a of the upper lid 16 and the hole 17e of the lower lid 17 through which the locking portion 32 of the inner lid holder 31 penetrates. If the inner lid 18 is removed, the inner lid holder 31 does not retreat even when the inner lid 18 is removed, and the locking portion 32 may be held in a protruding state. For this reason, even if the lid 15 is closed with the inner lid 18 removed, the latch 25 is locked between the upper lid 16 and the locking portion 32 and locked. Without knowing, it will be cooked as it is. In an electric rice cooker, if rice is cooked with the inner lid 18 removed, steam leaks, making it impossible to cook delicious rice, which is not preferable.
