Eventually, when a user selects a blowing direction mode using an external switch or the like, this signal is received and the fan unit 20 and the driving unit 50 are controlled.

Therefore, as described above, when the ultraviolet irradiation unit 30 moves until it is elastically supported by the supporting means 44 by the wind when exhausting by the fan unit 20, that is, when internal air is blown to the outdoor side. By the driving unit 50, each block body 31 is rotated 180 degrees to change the direction, move and then stop,

Conversely, even when air intake is performed by the fan unit 20, the driving unit 50 rotates each of the blocks 31 180 degrees to change the direction.

In this operation, the controller 60 controls the fan unit 20 and the driving unit 50 by receiving an external manipulation signal.
