DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric rice cooker, and more particularly to an electric rice cooker having an improved inner pot structure.

[0002]

2. Description of the Related Art An electric rice cooker has a structure in which an inner pot is housed in a main body container having a built-in rice cooker, and an upper opening of the main body container is closed by a lid, so that rice can be kept warm after cooking rice. It is configured as follows.

[0003]

In the electric rice cooker having the above structure, when the cooked rice in the inner pot is transferred to another container after cooking, or when the cooked rice in the inner pan runs out during the heat insulation, the inner cooker is cooked. If the inner pot is at a high temperature, as in the case of taking out the pot, there is a problem that it is difficult to take out the inner pot, so measures have been awaited.

In addition, since a circular pan is often used as an inner pan, there is a disadvantage that the inner pan is rotated at the time of taking out and it is difficult to take out the pot. Particularly, in recent years, in order to improve the heating state during cooking rice, In the meantime, there is a tendency to adopt a round bottom type with a large radius of curvature of the bottom curved part as the inner pan, in which case the inner pan becomes easier to rotate at the time of taking out or it becomes more difficult to take out There is a need for measures.

[0005] The present invention has been made in view of the above points, and it is possible to easily take out even when the inner pot is hot, and to prevent rotation of the inner pot in the main body container at the time of taking out. It is the purpose.
