PROBLEM TO BE SOLVED: To solve the problem of conventional air cleaners which form a cleaning space by making air flow collides, wherein the optimal air flow collision effects to important parts, such as a mouth and a nose, might not be achieved since air flow control corresponding to the movement of a human cannot be performed when used for a bed etc.SOLUTION: The wind amounts (wind speeds) of an air-blowing part 3 of a blower unit 1 and an air-blowing part 4 of a blower unit are regulated so that the air flow collides near the attitude, the position of a patient 5 detected by a human detection sensor 7, especially the position of the patient's head, optimizing so that the air flow collides near the head. As a result, using the diffusion and spread of the air flow by the collision of the air flow, the cleaning effect to the head including the mouth and throat and the spraying effects of ion, aroma, etc. can be improved. |
