Since the inclination angle of the inlet 66 of the joint 65 is steep, the water accumulated in the drain pan 54 tends to flow toward the outlet 67.
  • the joint 65 even if the position of the fan motor 13 in the cabinet 3 is lowered, by using the joint 65, it can be drained from the drain pan 54 through the lower portion of the fan motor 13. Therefore, the position of the fan motor 13 can be lowered, the height of the cabinet 3 can be lowered, and the cabinet 3 can be made compact.
  • the inclination of the joint 65 may be changed according to the position of the drain port 62 on one side, the position of the drain pan 54 can be freely set, and the cabinet 3 can be made more compact.
  • the joint is a curved tube so that the curvature on the front side of the joint is smaller than the curvature on the rear side.
  • the inclination angle of the inlet becomes steeper than the inclination angle of the outlet, and the joint is arranged so as to wrap around the outer periphery of the fan motor.

Abstract

La présente invention se rapporte à une unité intérieure pour appareil de conditionnement d'air, conçue d'une manière telle qu'un tuyau de vidange peut être facilement raccordé à un orifice de vidange même si l'orifice de vidange se situe devant le moteur de ventilateur. L'orifice de vidange (62) d'un bac de vidange (54) se situe devant le moteur de ventilateur (13) disposé sur un côté du ventilateur (2) dans la direction gauche-droite, et le raccord (65) destiné au raccordement de l'orifice de vidange (62) et d'un tuyau de vidange (60) qui est disposé à l'arrière du caisson (3) est disposé sur l'unité intérieure. L'angle d'inclinaison de l'orifice d'entrée (66) du raccord (65) qui est raccordé à l'orifice de vidange (62) est défini pour être plus aigu que l'angle d'inclinaison de l'orifice de sortie (67) du raccord (65) qui est raccordé au tuyau de vidange (60). Le raccord (65) est disposé de manière à être acheminé sous le moteur de ventilateur (13) le long de la périphérie extérieure du moteur de ventilateur (13), et l'orifice de sortie (67) du raccord (65) arrive derrière le moteur de ventilateur (13) et est raccordé au tuyau de vidange (60).
