ABSTRACT:
An oven door has a substantially vertical air passage through which air flows by convection. Air enters the air passage through air inlets at the bottom of a substantially rectangular decorative trim frame, which supports a front pane of glass, and the bottom of an inner liner to which the frame is attached. Air in the air passage flows over the substantially rectangular front pane of glass along its inner surface. The frame has air outlets, which are above the front pane of glass and communicate with the air passage to provide the only exit, to direct air substantially horizontally in the substantially horizontal plane of a handle assembly on the door. The frame has a baffle disposed within the air passage for deflecting air therefrom through the air outlets and over the handle gripping portion. The air passage is closed above the baffle, and stagnant air above the baffle functions as a heat insulator. Heat insulating door end caps overlie the sides of the frame and the front pane of glass from above the top of the frame to beneath the upper edge of the front pane of glass. The handle assembly includes a handle gripping portion and handle end caps, which mount the handle gripping portion on the door and are heat insulators.
