ABSTRACT:
An elongated relatively narrow vent member is mounted along the rear edge of a cooktop having a plurality of burners. The vent member has an air chamber formed therein which is coupled to a vent duct having a blower at the outlet thereof which provides suction in the chamber. A motor-driven drive system is provided to raise and lower an intake or "snorkel" member which is slidably mounted in the air chamber. The drive system operates in response to the actuation of a momentarily actuated pushbutton switch. The snorkel member has an intake slot formed along the top edge thereof such that when it is in its raised position, the intake slot is a substantial distance above the cooktop burners. In its lowered position, the snorkel member is fully recessed in the chamber and closes the vent system against backdrafts from the outside.
