By proceeding, it is possible to eliminate temperature unevenness of the food and overheating around the food. Further, the arm for stirring the food in the container is detachable from the connection shaft on the heating chamber, and has a simple structure in use.

According to a second aspect of the present invention, the drive setting of the stirring motor according to the first aspect can be freely operated by a button provided on a control panel.

According to a third aspect of the present invention, the agitating motor and the connecting shaft of the first aspect are obliquely held, whereby a wide range of agitation can be achieved along the outer periphery of the container containing the foodstuff.
