PURPOSE:To provide a compact air purifier efficiently purifying air without bringing about a large increase in cost. CONSTITUTION:A blade part 5c inclined in the same direction as a blade part 5b is formed to the blade part 5a of a fan 5 and a blade 5d inclined in the same direction as the blade part 5a is formed to the outside of the blade part 5b. Air is sucked within the rotary range of the blade parts 5a, 5b and blown off (discharged) within the rotary range of the blade parts 5c, 5d. Therefore, the suction and discharge of air can be performed by one fan 5. Partition walls 9 are provided to the parts corresponding to the middle points being the boundaries of the blade parts 5a, 5c and 5b, 5d of the fan 5. It can be prevented that the air streams due to the suction and discharge of air are short-circuited in the main body A by the partition walls 9. |
