For example, during the closing operation of the door, the on / off sound of the contact of the control switch for interlocking with the heating operation, the collision sound that occurs when the door contacts the main body, and the vibration that occurs at the time of the collision are used. It is uncomfortable for the person.

Various mechanisms for reducing the unpleasant noise generated during the closing operation of the door as described above have been proposed. However, in order to interlock with the door opening / closing mechanism, the mechanism becomes large and complicated. Have. Furthermore, providing such a mechanism within the casing of a small-sized cooker that is multifunctional and highly functional as described above is a major obstacle to achieving miniaturization due to restrictions on the arrangement space and arrangement position.
