<P>PROBLEM TO BE SOLVED: To provide an exhaust hood enabling efficient air exhaust without diffusing hot air generated from a heat source such as a kitchen, and alleviating wear due to hot air current. Ž<P>SOLUTION: By continuously changing the blowout direction of outside air from an air supply part from the directly underneath direction to the hood interior lower direction, a lid of outside air expanded below the hood to have a mountain shape is formed, so as to prevent diffusion of hot air, and at the same time, to alleviate ascending current.
