ABSTRACT:
The specification discloses a kitchen stove hood having two venting modes of operation. The kitchen stove hood is dimensioned to be disposed in a kitchen area over a stove and includes an air intake opening. An air recirculation outlet for recirculating filtered air to the kitchen area and an air vent outlet for venting air from the kitchen area is also included in the kitchen stove hood. A recirculation damper blade is mounted adjacent to the air recirculation outlet and is operable between an open and closed position. A vent damper blade is mounted adjacent to the air vent outlet and is operable between an open and closed position. The damper blades are interconnected by a damper blade linkage assembly which is operable to positively move the recirculation damper blade between its open and closed position while simultaneously moving the vent damper blade between its closed and open position. When the recirculation damper blade is open, the vent damper blade is closed thereby recirculating air to the kitchen. When the recirculation damper blade is closed, the vent damper blade is open to vent air outside the kitchen area.
