Ventilation structure of microwave oven and lamp fitting structure therefor

   
   

A microwave oven is provided which can prolong a lifetime of the oven's lamp by elimination of heat resistant tape fitted to the lighting window, and by optimizing cooling of the lamp. A ventilation structure of the microwave oven includes an air inlet, which also functions as a lighting window, located in one side of the upper surface of the cooking cavity, with the lamp mounted proximate thereto. The ventilation structure includes a ventilation motor and an air duct where the air duct guides cooling air past the lamp and into the cooking space through the air inlet.
