PROBLEM TO BE SOLVED: To provide an exhauster for contributing to an open large space such as a kitchen and a factory by creating a stable swirling air flow in a hood where a side wall is completely covered. SOLUTION: In the inside of a cylindrical hood whose lower portion is open, two air-blowing means are arranged on the inner wall of hoods at diagonal positions in a horizontal surface, air that is blown from each of the air-blowing means is blown in nearly a horizontal direction along the inner wall of the hood so that the same rotary direction results in the hood to form a swirling air flow that turns nearly horizontally in the hood, and a suction means for sucking the swirling air flow for exhausting is arranged at the center of the upper portion of the hood. |
