Document Type and Number:
Japanese Patent JPH05101880
Kind Code:
A
Abstract:
PURPOSE: To make the volume occupied by a fan and a heat radiation plate of an inverter power source small and also make the size compact in a high- frequency heating apparatus to heat and cook foods.
CONSTITUTION: Elemental parts such as a rectifier diode 3, a switching transistor 6, of an inverter power source are installed in a heat radiation plate 16 and a part of a casing 17 of a centrifugal type fan 11 to cool a magnetron is composed of the heat radiation plate 16. Without degrading the cooling function of the centrifugal type fan 11 and the heat radiation plate 16, the elemental parts are integrated and the size of an apparatus is made compact.
