PROBLEM TO BE SOLVED: To perform installation by a simple method with a strength and to improve cleaning ability, in a blower separation type range hood fan. SOLUTION: An installation state is stabilized through reliability on a mounting strength at fit-in effected through direct insertion of a multivane fan unit 2 in an insertion frame 4 and reduction of the weight of a hood 1 on which press throttling processing is applied. By effecting setting to the length of an air supply duct 3 between the multivane fan unit 2 and the hood 1, the hood 1 is disposed in a given height position without being influenced by the height of the exhaust port 101 of a room wall 100. An acute part, such as a flange, having a risk during cleaning is removed from an inner side. |
