INDUCTION HEATING COOKING APPARATUS

摘要

PURPOSE:To achieve quiet operation of a cooking apparatus by furnishing a fan motor driver circuit which controls the rotation of fan motor according to the power consumption of an inverter. CONSTITUTION:A fan motor driver circuit 5 is furnished to drive a fan motor 4 at a low speed when the power consumption of an inverter 3 is below a preset value. Further a temp. sensing device 6 is furnished to sense the temp. of the heat emitting part of inverter 3, and the low-speed operation of the fan motor 4 is permitted only when the temp. of this heat emitting part is low and safe operation of inverter is guaranteed. This enhances the safety and ensures quiet operation.
