AIR CONDITIONER

To suppress generation of dew condensation on a surface for defining a flow passage of air which has passed a heat exchanger.SOLUTION: An air conditioner includes: a cross flow fan 14; a heat exchanger which extends from a back side toward a front side of the cross flow fan 14 as if to cover the cross flow fan 14; a flow passage formation member 18b including a first surface 18u for defining the flow passage of the air which has passed the heat exchanger; a first drain pan arranged below a front end of the heat exchanger; a second drain pan arranged below a rear end of the heat exchanger; and a first water guide passage 18h provided on a second surface 18n of the flow passage formation member 18b on an opposite side from the first surface 18u, and for guiding liquid in the second drain pan to the first drain pan. The first water guide passage 18h includes a bottom surface existing in a downward direction while being separated from the second surface 18n of the flow passage formation member 18b.SELECTED DRAWING: Figure 9 【課題】熱交換器を通過した空気の流路を画定する表面上での結露の発生を抑制する。【解決手段】空気調和機は、クロスフローファン１４と、クロスフローファン１４に覆い被さるようにクロスフローファン１４の後方から前方に向かって延在する熱交換器と、熱交換器を通過した空気の流路を画定する第１の表面１８ｕを備える流路形成部材１８ｂと、熱交換器の前端の下方に配置された第１のドレンパンと、熱交換器の後端の下方に配置された第２のドレンパンと、第１の表面１８ｕとは反対側の前記流路形成部材１８ｂの第２の表面１８ｎに設けられ、第２のドレンパン内の液体を第１のドレンパンに導く第１の導水路１８ｈとを有する。第１の導水路１８ｈが、流路形成部材１８ｂの第２の表面１８ｎから離れつつ下方向に延在する底面を備える。【選択図】図９
