ABSTRACT:
The preferred embodiment hereby discloses a unique configuration for a microwave oven to effect the efficient cooling of both the high-voltage transformer and the magnetron with a blower, in which the high-voltage transformer is secured to the air-intake port of the blower, and the magnetron and the exhaust outlet are aligned parallel to each other on the upper sides of the blower unit, thus effectively minimizing resistance to air ventilation through the blower unit, and, as a result, significantly improving the operative efficiency of the blower unit and the actual cooling effect on the high-voltage transformer. In addition, this improved cooling system offers great advantages with the possibility of savings in production costs through the realizable reduction in coil diameter of a high-voltage transformer due to the improved temperature control of the cells of such high-voltage transformers.
