PROBLEM TO BE SOLVED: To provide a ceiling-embedded ventilation fan that prevents dew condensation water running along a power wire from entering a connection terminal. SOLUTION: A canopy 14 covers above and both sides of a connection opening 13, a bottom of the canopy 14 is located on a position sufficiently lower than an insert hole of the connection opening 13, and an eddy plate 17 is disposed on a position close below the insert hole 15 and is located so that a descending slope from the connection terminal 12 toward an opposite side thereof is disposed when the insert hole 15 of the connection terminal 12 is viewed in a front view. Accordingly, droplets running along the power wire come into contact with the eddy plate to be increased in size, and then run along the slope of the eddy plate 17 to run down a frame top surface below. As a result, the ceiling-embedded ventilation fan is obtained which causes an effect that dew condensation water is prevented from entering the power terminal. COPYRIGHT: (C)2012,JPO&INPIT |
