Thus, a flow of air is created in the outer case, air in the room is taken in from a suction port (not shown), and the purified air is discharged from an outlet (not shown) through the outer case and returned to the room again.

At this time, first, coarse dust is removed by a pre-filter (not shown) provided at the back of the suction port, and then the dust in the passing air is ionized by the ionization unit 10 and the ionized dust is collected by the dust collection unit 11. It is electrostatically adsorbed to the GND plate 11a and an odor component is adsorbed by a deodorizing filter (not shown).

By the way, the air purifier described above has a structure shown in FIG.
Is provided with an ionizing ray cleaning device 20 according to the present invention.

In the ionizing ray cleaning device 20, a feed screw shaft is rotatably provided on the outer frame of the ionizing section 10 in parallel with the ionizing line 10b (not shown). On the feed screw shaft, a moving member (not shown) is provided so as to be reciprocally movable by screwing its female screw portion. As shown in FIG. 1, a pair of fixed shafts 30 are provided upright on the moving member, and the fixed shafts 30 are fitted into respective center holes to provide a roll-shaped cleaning member 25.

As a result, there is no possibility that the cleaning member is caught by a foreign substance during the movement as in the prior art and stopped. As a result, when the air cleaner is used, the cleaning member leaks from the ionization line via the stopped cleaning member. An electric current can be generated, which can prevent smoke and ignition. Further, it is also possible to prevent the stopped cleaning member from obstructing the flow of air, generating abnormal noise, and preventing the adverse effect of reducing the air volume in the machine.

According to the third aspect of the present invention,
Since the foreign matter adhering to the ionizing line is wiped off by sandwiching the ionizing line between the pair of roller-shaped cleaning members, the ionizing line can be more effectively cleaned.
