摘要： An oven door includes a peripheral frame, an internal transparent pane adhesively secured to the frame and an external transparent pane releasably mounted on the frame. The frame has lower and upper rims formed with openings for the circulation of air through an interspace between the two panes. A profile member is secured to the upper rim of the frame and has a central handle. The profile member has an internal cavity communicating with the openings of the upper rim and with the interior of the oven chamber. First deflector elements within the internal cavity direct a flow of air from the interior of the oven into the interspace. Second deflector elements within the cavity define venturi-type passages for facilitating the escape of air from the interspace.
