<p>An exhaust hood comprising: a hood main body (110) provided with a canopy (111) having a suction portion (115) disposed at a lower portion thereof for sucking air and disposed to be upwardly inclined in a forward direction, and an exhaustion portion (121) perpendicularly formed for discharging the sucked air to the exterior; an air supply fan (135) disposed in the hood main body (110) for blowing air; and a nozzle unit (141) formed at a front end region of the hood main body (110) for spreading the air blown by the air supply fan (135) toward the suction portion (115) by being inclined by a particular angle, whereby contaminated air which flows toward the exhaust hood without being sucked therein can effectively be induced and collected into an inlet, thereby enabling the creation of more comfortable cooling environment and experimental circumstance.</p> |
