PURPOSE:To improve cooling properties for heating components of induction heating control circuit in a heating cooker which employs induction heating by covering heat sinks with a heat sink cover which is provided in parallel to flow of cooling wind and forming an air flow passage of a cooling fan within the heat sink cover. CONSTITUTION:A plurality of heat sinks 1 are mounted on a heat sink cover 2 which is molded of resin and shaped to cover the heat sinks 1 in parallel to flow of cooling wind and arranged between the heat sink cover 2 and a fixing plate 28. The cooling wind from a cooling fan 8 is sent by a duct 10 through an opening 5 formed in a partition 7 into the heat sink cover 2. As a result, the heat sinks 1 can be cooled efficiently by wind volume. |
