The suction panel is formed to rotate with an axial direction of an air blowing fan or a direction perpendicular to the axial direction of the air blowing fan as a rotation axis to be coupled with or separated from the housing. Accordingly, a user may easily and intuitively separate the suction panel and falling of the suction panel, which may occur when the suction panel is separated, may be effectively reduced using a supporting unit disposed at the suction panel. Also, the housing and cover members which cover an outer perimeter of a lower portion of the housing may be coupled with each other by pressurizing the cover members toward the housing, thereby allowing the user to easily coupled the cover members. ## Claims ### Claim 1 An air conditioner comprising: a housing including: a cylindrical portion, and a discharge port arranged at an inner side of an inner circumferential surface of the cylindrical portion and provided in an arc shape;
