Abstract

PURPOSE:To prevent dropping of water to a space in the ceiling, by making a cut in a side face of a casing at the portion thereof located under the joining portion of the casing and a joint of an exhaust duct, and projecting the cut outwards in a tilted manner, so that it provides a water collecting section communicated to both sides of the casing. CONSTITUTION:A cut is made in a side face of a casing 1 at the portion thereof located under the joining portion of the casing 1 and a joint 8 of an exhaust duct, and the lower portion of the cut is bent outwards in a tilted manner, so that it provides a water collecting section 10 communicated to both sides of the casing 1. With such an arrangement, water leaked from the joining portion of the exhaust duct 8 flows downward along the side face of the casing 1 and is introduced into the casing 1 from the water collecting section 10 by the suction force acted in the casing 1. Then, water thus introduced into the casing 1 is discharged to the outside via a tube connected to a drain pipe (not shown).
