PURPOSE:To provide a bath room ventilation structure which is capable of designing or constructing a bath room without any restrictions imposed by ceiling structural materials and preventing water from being collected in a duct. CONSTITUTION:A bath room 13 consists of an outer peripheral wall 12 and an inner peripheral wall 14, thereby forming a double structure. This structure allows an exhaust air passage 16 to be formed so that the air in the bath room 13 may be circulated in the bath room from the top to the bottom. The upper end of the exhaust air passage 16 is used as a ventilation port 22 and connected to a duct 24 which communicates with the outside at the lower end of the exhaust air passage 16 and comprises a ventilation fan 26. A drain port 28 is installed to the bath room 13 rather than the ventilation fan 26 so that the water collected in the duct 24 may be drained from this drain port 28. |
