CONDENSATE FALLING PREVENTION APPARATUS FOR BATH ROOM VENTILATING FAN

PROBLEM TO BE SOLVED: To obtain a ventilating fan capable of preventing water droplets from falling down into a bath room by spouting out condensate in a case of the ventilating fan together with a circulation flow by providing a vertical wall along the periphery of a circulation outlet for preventing the water droplets accumulated on the bottom of the case from going out from the circulation outlet to the side of the bath room. SOLUTION: A fan case 4 is contained in an outer case 3, and a circulation outlet 11 is formed at one position of the bottom 9 of the fan case 4 for branching part of air exhausted from a fan 5 to the side of an exhaust pipe 7 into a chamber in the outer case 3. A vertical wall 12 yielded by folding the edge of the bottom 9 of the fan case 4 upward is provided over the entire periphery of the peripheral part of the circulation outlet 11, and part of exhaust is circulated from the circulation outlet 11 through the chamber to the side of a bath room 8 whereby a wall surface of the bath room 8 is dried. Hereby, condensate in the case 4 of the ventilating fan is spouted out together with the circulation flow, and hence the condensate is prevented from falling into the bath room 8.
