The operation of the present invention having the foregoing configuration will be described.

When the air conditioner is in operation, the ionizer 40 may be turned on, and the ionizer 40 may have the carbon fiber electrode 130 discharged by the high voltage applied thereto from the high voltage generator 20. When the carbon fiber electrode 130 discharges, the molecules of the air surrounding the carbon fiber electrode 130 may be ionized into anions, such as OH-, and O- so on, or cations, such as H+. The foreign matter in the air may be charged by the anions, or cations produced from the ionizer 40, and may flow to the pre-filter 13 in a charged state. Large foreign matter in the air flowed to the pre-filter 13 may be filtered out at the pre-filter 13, and small foreign matter in the air flowed to the pre-filter 13 may not be filtered out at the pre-filter 13, but may pass through the pre-filter 13. The small foreign matter pass through the pre-filter 13 may flow to the electrostatic filter 60 in a charged state, and stick to the electrostatic filter 60 when the small foreign matter passes through the electrostatic filter 60. Micron sized particles, such as the cigarette smoke, may not be filtered out at the pre-filter 13, but may pass through the pre-filter 13. Since the micron sized particles pass through the electrostatic filter 60 in the charged state by the ionizer 40 mounted to the air inlet 4, the micron sized particles may stick to the electrostatic filter 60 easily. Eventually, the air passed through the electrostatic filter 60 may flow in a state the micron sized particles, such as the cigarette smoke, are removed from the air. The air passed through the electrostatic filter 60 may be brought into contact with the heat exchanger 7 so as to be heated or cooled, and may be discharged to the air outlet 6 passed through the fan 8. Accordingly, the air conditioner can enhance cleanness of the room better than a case the ionizer 40 is turned off, and, particularly, can remove cigarette smoke and the like, efficiently.

In the meantime, at the time of service of the ionizer 40, a service man can separate the ionizer 40 toward an upper side of the air inlet 4, without disassembling the body 2. The ionizer 40 separated from the body 2 thus can be serviced. In the meantime, the service man can separate the cover 140 from the housing 100 in a state the housing 100 is secured to the upper side of the body 2, and, it is also possible that the PCB 110, the wire 120, and the carbon fiber electrode 130 are serviced in a state the housing 100 is positioned at the body 2.

It will be apparent to those skilled in the art that the present invention is not intended to be limited to the above-described embodiment and drawings, and various changes or modifications may be made therein without departing from the scope and the technical sprit of the present invention.
