Title: Microwave oven with triangular observation window

Abstract: A microwave oven comprising a cubical casing with front edges of its side walls cut diagonally at an angle and with its top wall made much shorter than the lower wall for hingedly supporting a door slantwise at the front edge of the top wall. The door is provided with a see-through observation window of triangular cross section projecting outwardly from its surface, so that the inner surface of the window forms part of the heating room together with the casing upon closure of the door, while an object being heated in the oven is readily observed through the window from various angles during cooking without requiring any separate illuminating source.
