PROBLEM TO BE SOLVED: To provide a range hood having enough silence effect and improved in blowing properties.SOLUTION: A range hood 1 includes: a hood part 3 collecting air at an upstream side on an air flow 2; and an exhaust part 4 exhausting air corrected by the hood part. Two active muffling air ducts having a square cylinder shape inside the exhaust part 4 is formed into a chevron shape toward the hood part 3 (from a downstream side to an upstream side) from a blowing part 8 so as to be slanted each other.SELECTED DRAWING: Figure 1 |
