Abstract
Abstract The invention relates to a cooking range with an oven which is provided with an inspection port adjacent a top front edge of the cooking range, the inspection port comprising two parallel-spaced vertically inclined transparent panes between which a passage is defined. Cooling air enters said passage from an inlet in the front of the cooking range and gets vented into the bottom region of the cooking top of the range. The transparent panes can be viewed to see the inside of the oven by a person standing in an upright position.
