PROBLEM TO BE SOLVED: To stabilize cooling in a cooking chamber, to resist rust and corrosion on the outer surface inside the cooking chamber caused by dew, to realize high quality cooling, and to improve durability, relating to a cooker that performs induction heating and food thawing with high frequency while cooling the surface of the food. SOLUTION: A cold air sealing gasket 50 seals the space between the opening periphery of the cooking chamber 25 and a door 27, a high-frequency permeating heat insulator and an airtight sealing material seals a communicating passage between the air within the cooking chamber 25 and the air outside is formed in a waveguide portion, O-ring sealing member 39 seals a communicative passage between the air within the cooking chamber 25 and the air outside is formed in a food dish rotating motor shaft 37, and a high temperature refrigerant circulating pipe 35 is disposed at a portion of the inside of an outer housing corresponding to the waveguide portion and the food dish rotating motor shaft 37. This reduces a thermal conduction load within the cooking chamber 25, thus preventing invasion of the air outside and the dew on the surface of the outer housing. COPYRIGHT: (C)2004,JPO
