PROBLEM TO BE SOLVED: To improve performance of an air conditioner and to prevent dew condensation from generating in the vicinity of a blowout port lower end part by suppressing generation of a vortex in the vicinity of horizontal blades at the blowout port lower end part.SOLUTION: An indoor unit 100 for air conditioner includes: a vertically long rectangular parallelepiped housing 1; a blower 2 installed at a lower part in the housing; a heat exchanger 3 arranged at an upper part of the blower 2 in the housing; a suction port 5 provided at a lower part of the housing; a blowout port 9 provided at an upper part of the housing 1; and a plurality of horizontal blades 8 provided at the blowout port 9 and disposed vertically so as to change the direction of blowout air. Air is sucked from the suction port 5 by the blower 2, it is allowed to pass the heat exchanger 3, and the air is blown out from the blowout port 9. Out of the plurality of horizontal blades 8, a horizontal blade 8a at the lowermost part has an extension part in which an upstream side is constituted to be longer than the other horizontal blades 8 provided above the lowermost part horizontal blade 8a, and the extension part is constituted in a shape bent downward.SELECTED DRAWING: Figure 1 【課題】吹出口下端部の水平羽根付近での渦の発生を抑制して、空気調和機の性能向上及び吹出口下端部付近に結露が発生するのを防止する。【解決手段】空気調和機の室内機１００は、縦長の直方体状の筐体１と、この筐体内部の下部に設置された送風機２と、筐体内部における送風機２の上部に配置された熱交換器３と、筐体の下部に設けられた吸込口５と、筐体１の上部に設けられた吹出口９と、吹出口９に設けられ吹出し空気の方向を変えるために上下方向に配設された複数の水平羽根８とを備え、送風機２により吸込口５から空気を吸い込み、熱交換器３を通過させた後、吹出口８から空気を吹き出すように構成されている。複数の水平羽根８のうち最下部の水平羽根８aは、その上流側を、最下部の水平羽根８aよりも上方に設けられた他の水平羽根８よりも長く構成した延長部を有し、且つこの延長部を下向きに曲げた形状に構成している。【選択図】図１
