COOLER FOR MICROWAVE OVEN

摘要

PURPOSE: A cooler for a microwave oven is provided to increase the cooling efficiency by improving the ventilating power through a DC fan motor. CONSTITUTION: A cooler is performed by: reducing AC power by forming a tap to a primary coil(7a) of a HVT(high voltage transformer); converting the AC power into DC power through a bridge-type rectifier of a rectifier(120); and feeding the stable power to a fan motor(100). The fan motor is for DC power to increase the rotational frequency in proportion to the fed voltage. Therefore, the cooler increases the cooling efficiency by improving the ventilating power through the increased rotational frequency of the fan motor.
