Title: Cooker
Inventor: MORI YASUHISA
IPC: F24C7/06
Filed: 2001-03-08
Abstract: PROBLEM TO BE SOLVED: To solve a problem that a heat insulating performance exceeding a conventional one can hardly be attained even if a matellic heat insulating plate such as plated metal sheet having a high heat reflectance is employed as a heat insulation constitution of a face type heating element or a combination with glass wool or ceramic wool is employed as far as its thickness is same as that of the conventional constitution.
