Abstract
Abstract An oven exhaust deflector deflects smoke, gases and fumes issuing from an oven when the oven door is left ajar during broiling to an exhaust hood above the oven. The deflector includes a sheet of flexible, heat-resistant material wound up on a spring-loaded roll affixed inside the front edge of the hood. During broiling, the sheet is unrolled and attached to the handle on the open oven door so that smoke and gases issuing from the oven are guided upwardly into the exhaust hood by the unrolled sheet. When the oven is not being so used, the deflecting sheet is wound up on the roll inside the hood.
