摘要：PURPOSE:To facilitate a piping work, restrict a reduction in strength of an outer wall and prevent an amount of air of a duct ventilation fan from being decreased even in the case of performing a simultaneous operation of a range hood fan and the duct ventilation fan by a method wherein the range hood fan and the duct ventila tion fan are mounted. CONSTITUTION:A kitchen range hood fan 11 is constructed such that an air blower 13 is arranged within an outer frame 12 having its lower surface released to open and further it is mounted above the range in a kitchen 14. A duct ventilation fan 29 mounted at a ceiling in a toilet 30 is constructed such that an air blower is arranged within an outer frame 31. A connection duct 32 connected to a discharging port 33 of a duct ventilation fan 29 may be arranged up to the range hood fan 11. As an evacuation duct 21 communication with an outdoor part, only one discharging duct 21 for the range hood fan 11 is sufficient. Accordingly, a piping work can be facilitated, only one hole 24 can be made at the outer wall 22 and a reduction in strength of the outer wall 23 can be prevented. In addition, the discharging performed by the duct ventilation fan 29 is always carried out through the range hood fan 11, so that even in case that the range hood fan 11 and the duct ventilation fan 23 are simultane ously operated, an amount of air of the duct ventilation fan 23 is not reduced.
