Abstract
An electric range having a solid glass-ceramic cooktop with a baking oven positioned beneath the cooktop. The oven includes a vertical exhaust duct joined to an oven vent means associated with the top wall of the oven and extending to an exhaust opening in the backsplash of the range. The vertical duct has a cooling air entry at its bottom portion for entry of relatively cool dry air for mixing with the oven gases prior to discharge of the oven gases from the exhaust opening. The oven vent means includes a restricted vent opening communicating with an air trap in the form of an elongated tube having a cross sectional area approximately equal to that of the restricted vent opening and extending vertically upwardly into the bottom portion of the exhaust duct a sufficient height above the air entry that the flow of hot gases through the restricted vent opening and tube increases the upward draft of cooling air and prevents backdrafts from exiting down through the air entry under both normal and oven overload conditions.
