<p><P>PROBLEM TO BE SOLVED: To heighten the efficiency of induction heating, to secure high durability, and further to facilitate repairing in a heating cooker jointly using induction heating and high-frequency heating. <P>SOLUTION: In the base part 3b of a cooking chamber 3, the main base plate 200 provided with a recessed part 201 whose base is an opening part 202 in the substantially center and a punched plate 203 provided with a number of small holes 204 having a predetermined diameter are integrated with each other. The punched plate 203 allows a magnetic flux to pass therethrough and inhibits passing of microwaves supplied into the cooking chamber 3. A placing table 21 made of crystal glass is housed in the recessed part 201, and an induction heating coil 24 is disposed under the punched plate 203 through a heat insulating material 22 and an insulating plate 23. The heat of heated material stored in the cooking chamber 4 is intercepted by the heat insulating material 22 so that the coil 24 is not heated, and the distance between the coil 24 and the heated material can be reduced to achieve high heating efficiency. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
