The present invention relates to a ventilator installed inside the ceiling of a bathroom or a toilet. The purpose of the present invention is to provide the ventilator which is capable of reducing manufacturing costs, and stably or easily installing the same at the upper side of the ceiling regardless of the size of the ceiling by excluding a rectangular ventilator main body generally applied as the component of an existing ventilator for the bathroom. The ventilator according to the present invention comprises: an upper fan scroll case part (110) forming the upper side of a bell mouth (102); a lower fan scroll case part (210) forming the lower side of the bell mouth (102); a rotary fan (300) mounted inside the upper fan scroll case part (110); a driving motor (400) driving the rotary fan (300); an upper and a lower blocking case (510, 610) blocking the upper and the lower opening ends of the upper and the lower fan scroll case part; and coupling units (800, 802, 900) fixing the lower blocking case to a fan scroll case so that a height between the lower blocking case and the lower fan scroll case part is controllable. The ventilator according to the present invention is capable of innovatively reducing the manufacturing costs, easily inserting and installing the same inside the ceiling, and stably installing the same even if the thickness of the ceiling varies. |
