PROBLEM TO BE SOLVED: To prevent an intake port from being blocked by a tablecloth or newspaper, to secure the cooling capability of a fan, to reduce the possibility that the temperature of the circuit components of a drive circuit abnormally rises to cause the failure of an apparatus, and to improve reliability by providing an intake block limiter section suppressing blocking of the intake air on a main body case including the intake port. SOLUTION: An intake port lattice 17 is formed at the lower section and side peripheral section of a cooling fan 16 so that hands are kept in no direct contact with the cooling fan 16 cooling a drive circuit 15, and a protruded shape 18 is formed downward into a rib shape on the intake port lattice 17. When a tablecloth or newspaper 10 is spread on a base 19 and an induction heater cocking device is placed on it and the cooling fan 16 is rotated, the tablecloth or newspaper 10 is sucked to the intake port grill 17 to block the intake air. The downward protruded shape 18 formed on the intake port grill 17 prevents the tablecloth or newspaper 10 from being stuck to the intake port 17 from below to block the intake air. |
