PURPOSE:To facilitate attaching and piping works of the range hood by a method wherein chamber parts are provided in an air supplying path and an air discharging path in order to permit to take out an air supplying duct as well as an air discharging duct from either surface of the chambers. CONSTITUTION:When blades 5 are rotated, indoor air, induced from the indoor side suction port 16 of an air discharging path 3, is discharged to the outside of a room from the air discharging duct 13 through the air discharging path 3 and an air discharging chamber 12 as shown by D D' and atmospheric air, induced from the air supplying duct 8 provided in the air supplying chamber 7 of the air supplying path 2, is supplied into the room from an indoor side discharging port 15 through a muffler 10 as shown by E E' by a pressure difference between the indoor and outdoor, which is caused by the discharging. The outdoor side suction port 9 may be provided at any position of the air supplying chamber part while the discharging port 14 may also be provided at any position of the air discharging chamber part 12. The path of supplying air may be selected so as to be F E', G E' or H E' while the path of discharging air may be selected so as to be D I, D J or D K. |
