Further, a ceramic protective layer 313 is formed in a portion excluding the discharge electrode 311 and the induction electrode 312. Here, when a high voltage of a positive component is applied between the discharge electrode 311 and the induction electrode 312, moisture (H ₂ 0) in the air is ionized by plasma discharge in the first electrode 310, and hydrogen ions (H ⁺ ) Occurs.

  The second electrode 320 is formed on the upper surface of the base portion 300a so as to be spaced apart from the first electrode 310 by a predetermined distance. The second electrode 320 is formed in a shape protruding at the base portion 300a so as to have a height. A plurality of the second electrodes 320 may be provided at positions separated from the first electrode 310.

When a negative high voltage is applied to the second electrode 320, positive ions accumulate around the second electrode 320 due to plasma discharge, and a large amount of electrons (e ⁻ ) are released into the air by the second electrode 320. Is done. Since a large amount of electrons released into the air are very unstable, they are trapped by oxygen molecules (O ₂ ) and form superoxide anions (O ₂ ⁻ ). Therefore, when a high negative voltage is applied to the second electrode 12, electrons and superoxide anions are generated.

  When electrons are emitted from the second electrode 320, the electrons are generated by the first electrode 310 and combined with hydrogen ions that pass around the second electrode 320 to form hydrogen atoms (hereinafter referred to as “active hydrogen”). Will be generated. At this time, since the blower fan 200 is provided in the lower part of the ion generation unit 300, the hydrogen ions generated in the first electrode 310 are combined with the electrons generated in the second electrode 320 so that the hydrogen ions are combined. It is sent in the direction of two electrodes 320.

However, it can also be configured to be directly adjacent to the discharge port 120 that is the outlet of the discharge flow path (P2) and to mix the scent into the discharge flow path (P2).

  The incense storage unit 410 is detachably provided on the back surface of the main body 100. The incense holder 410 is open at the bottom, and a solid or liquid fragrance is received inside and the scent is discharged through the bottom. Since the suction port 110 is formed on the back surface of the main body 100, the incense storage unit 410 is provided on the upper side of the suction port 110 of the main body 100. It is preferable to be added to.

  Grip portions 410 b are provided on both sides of the incense storage portion 410 so as to be detachable from the back of the main body 100. The grip portion 410b is formed outward on both sides of the incense storage portion 410, and includes a grip mounting portion 103a so that the grip portion 410b can be slid and sandwiched on the back surface of the main body 100. 410 is opened and closed by sliding in the front-rear direction. In this case, the grip portion 410b is made of an elastic member, and can be elastically fixed and supported on the back surface of the main body 100 by being pressed inward and seated on the grip mounting portion 103a.

  The incense cartridge 400 is provided with an incense guide unit 420 that guides the fragrance (Aromatic) stored in the incense storage unit 410 to the discharge channel (P2). The incense guide unit 420 is provided integrally with the incense storage unit 410 so as to be opened so that the scent naturally diffused by the fragrance (Aromatic) can enter the discharge channel (P2).

  The scent cartridge 400 includes a filter unit 500 that purifies air that is sucked from the outside through the suction port 110. The filter unit 500 includes a large number of filter assemblies, and can be configured to have various functions such as eradication of bacteria and antibacterial action as well as removal of foreign substances in the air.

  With such a configuration, the incense storage unit 410 is opened to receive a solid or liquid fragrance (Aromatic) inside the incense storage unit 410, and the naturally scented scent is lowered. At this time, the fragrance naturally diffused together with the air forcedly sucked into the main body 100 by the blower fan 200 passes through the discharge flow path (P2) through the blower fan 200. Then, the ions generated by the ion generation unit 300 are discharged outside through the discharge port together with the ions generated by the ion generation unit 300.

  On the other hand, if the function of the fragrance deteriorates after being used for a long time, the incense holder 410 is opened outside the main body 100. The grip part 410b provided outside the incense storage part 410 is pressed and released while sliding in the front-rear direction along the grip mounting part 103a formed on the back surface of the main body 100. Therefore, the main body 100 is not disassembled, and the fragrance storage unit 410 is simply opened to the outside of the back surface of the main body 100 to replace or supplement the fragrance (Aromatic).

  Next, the operation of the air cleaner according to the embodiment of the present invention configured as described above will be described.

  First, when the motor 210 is driven, indoor air is sucked into the main body through the suction port 52a while the blower fan 200 is rotated. The air sucked through the suction port 110 is purified while passing through the filter 500, then blown to the discharge port 120 side by the blower fan 200 and discharged to the indoor side. At this time, the fragrance (Aromatic) provided on the upper side of the suction port 110 of the main body 100 is naturally diffused and naturally added to the air to be inhaled, and discharged together indoors, which is comfortable for the user. The room air is supplied.

  At the same time, the active hydrogen and the superoxide anion are discharged together by the ion generation unit 300 provided adjacent to the discharge port 120. When the active hydrogen and the superoxide anion are discharged into the air, the superoxide anion having the opposite polarity to the static electricity of the bacteria is adsorbed on the surface of the bacteria by the static electricity of the bacteria floating in the air.

  When the superoxide anion is adsorbed to the bacteria, the active hydrogen is adsorbed to the superoxide anion by the superoxide anion. Therefore, the contacted superoxide anion and active hydrogen form a hydroperoxy radical (O—O—H), and the electrons of the superoxide anion offset each other with the static electricity of the bacteria. Hydroperoxy radicals take two hydrogen atoms from proteins, which are components of bacterial cell membranes, to produce two molecules of water. Thus, the protein molecules in the cell membrane deprived of hydrogen atoms are destroyed, thereby destroying the bacterial cell membrane and killing it.
