The lid 12 is disposed on the pot body 11 in an openable and closable manner. The lid 12 can be pivotally connected to the pot body 11, for example, via a pivot shaft, and can freely pivot about a pivot axis on which the pivot shaft is located between a closed position and an open position relative to the pot body 11, thereby facilitating the closing and opening of the pot body 11.

[0046] The pot body 11 includes an inner pot 100 and a cylindrical storage area. The inner pot 100 can be freely placed in and removed from the storage area, making it easy to clean. The inner pot 100 is typically made of metal and has a circular opening on its upper surface for holding ingredients to be heated, such as rice or soup. More specifically, the pot body 11 includes a base, an outer shell, and a middle plate. The outer shell is attached to the base, and the middle plate is attached to the outer shell. The middle plate has an opening that allows the inner pot 100 to enter.
