[0008]

As described above, according to the present invention, an air curtain is defined for each person or for each of a plurality of persons or groups.
Since it is possible to prevent the dirty air of the group from moving to an adjacent person / group, it is possible to prevent the other person from being disturbed by the dirty air such as cigarette smoking. Also, since the dirty air is cleaned and returned, the air environment is improved. Further, in the present invention, since the air is circulated and cleaned, the room temperature is not changed, so that the air conditioner can be used together with a temperature controlling air conditioner. Also, if the air cleaner is automatically operated by the human sensor, useless operation of the air cleaner can be reduced and running cost can be reduced. In the case where an air chamber is provided in an air purifier and a partition wall is provided in the air chamber to divide the air flow, the air flow can be substantially uniformly distributed in a required direction with a simple structure. In addition, a device in which a titanium oxide plate irradiated with ultraviolet rays is brought into contact with air can efficiently decompose tobacco smoke and odor, and can deodorize and deodorize.
