Windowed and choked combination oven door

摘要

A windowed door assembly for a combination microwave and hot air oven having a choke-coupling type seal formed around the periphery of the window opening to suppress the leakage of microwave energy from the area between the main body of the door and the window portion of the door. The window portion is removably connected to the main body of the door in a region of relatively high capacitive impedance to reduce the importance of the mechanical connection in suppressing the leakage of microwave energy from the oven.
