<p>According to the present invention, a water-conducting path (34) for guiding drain water in the rear-side drain pan (33) to the front-side drain pan (30) is provided to the side of the air passage (4), and a dripping section (36) at the front end of the water-conducting path (34) is positioned above the front-side drain pan (30). A forward extension wall (40) formed by extending an air-passage-side side wall (35b) of the water-conducting path (34) forward, and a rearward extension wall (41) extending downward from the front end of the water-conducting path (34), are formed around the dripping section (36). The extension walls (40, 41) surround the dripping section (36) and obstruct the airflow in the vicinity of the dripping section (36) created when the air passage (4) is in negative pressure. The drain water leaving the dripping section (36) flows down along the extension walls (40, 41). The effect of wind generated by the fan (6) in the air passage (4) is thereby minimized, and the drain water is prevented from entering the air passage (4).</p> |
