PROBLEM TO BE SOLVED: To provide an air cleaner capable of switching between a top-blowing state in which a lot of clean air is blown upward, and a front-blowing state in which a lot of clean air is blown frontward, and capable of suppressing increase in pressure loss according to the switching between the top-blowing state and the front-blowing state.SOLUTION: In a casing 11, one outlet 30 which is opened facing upward to blow out clean air, and a curved surface 35 which continues to a side 32 on a front side of the outlet 30 and along which airflow from the outlet 30 goes by the Coanda effect are formed. A horizontal blade 40 is arranged in the outlet 30, and it is configured in such a manner that it can be switched between: a first posture of a top-blowing state in which clean air can mainly be blown out upward; and a second posture of a front-blowing state in which clean air is blown obliquely frontward by generating more airflow by the Coanda effect than in the top-blowing state by the curved surface 35. |
