Abstract

PURPOSE: To facilitate removal of a main body frame, in a ventilation fan for duct installed inside a ceiling, etc., by installing an exhaust joint mechanism, equipped with an intermediate joint board and an exhaust frame, onto an exhaust gate wall surface of the main body frame in a free-to-put-on-and-off manner.
CONSTITUTION: A ventilation fan for duct has a cylindrical motor base 5 located inside a main body frame 1, and a motor 15 which is equipped with a fan 18 is tightly mounted onto this base. A grille 37 is installed under the fan 18 by a grille- installing mechanism 27 in a free-to-put-on-and-off manner, and at the same time, an exhaust joint mechanism 42 is provided on wall surface of an exhaust gate 7 of the main body frame 1. This exhaust joint mechanism 42 is provided with an intermediate joint board 43 which is connected, as a continuous body, with an exhaust frame 44 equipped with an opening coinciding the exhaust gate 7. The exhaust frame 44 has a tapered section 45, and a shutter 46 which is equipped with a damper 47 is installed on this trapered section's tip opening in a free-to-rotate manner. And this joint mechanism 42 is fixed to the frame 1 by a top slope section 55 and a bottom fixing section.
