An example of the form is classified into a pendant type configured to be installed on the ceiling, a bracket type configured to be installed on the wall, and a stand type configured to be installed on the floor.

And it is to be understood that the invention is not limited to the specific forms referred to in the above description, but rather includes all modifications, equivalents and substitutions within the spirit and scope of the invention as defined by the appended claims. It should be understood that.

Referring to the action of the sterilizing purifier of the indoor air of the present invention configured as described above are as follows.

First, the present invention has a forced suction of the indoor air by the intake fan 21 and forced discharge of the purified air by the discharge fan 81 as shown in Figs.

That is, the rear end of the suction fan 21 is arranged in a compact screen 30 in a standard that does not interfere with the inflow of air to block the inflow of foreign substances having a scale according to the forced suction, the forced suction is copper ions While vortexing in the generator chamber 40 and passing through the copper ion generator 50, sterilization, deodorization, oxidation of residues, etc. are performed by copper ionization reaction and photocatalytic reaction of titanium oxide, and at the same time, a cold cathode ultraviolet fluorescent lamp 42 Sterilization is performed by.

The primary inflow air purified above is passed through the HEPA filter 60 and the fine particles are filtered, and then passes through the zeolite filter 61 to control humidity and deodorize. Inlet air, which has been passed through the zeolite filter 61 and purged in the third, passes through the activated carbon filter 62 and is deodorized. Finally, through the filter nonwoven fabric 70 containing the activated carbon component and silver component is sterilized again, harmful electromagnetic waves generated inside the air purifier is blocked and discharged into the room through the discharge hole (82).

In more detail, the air forcedly sucked by the suction fan 21 is vortexed in the copper ion generator chamber 40 and is repeatedly convection passing through the copper ion generator 50 installed at both sides and the lower side of the copper ion generator chamber. Thus, the introduced air is convection with sufficient contact with the titanium oxide coating surface and the copper surface.

Therefore, deodorization, sterilization, and oxidation of residues are carried out by ionization of copper and photocatalysis of titanium oxide (TiO ₂ ) coating film, and at the same time, sterilization is performed by cold cathode ultraviolet fluorescent lamp 42, so that the introduced air is 1 It is purified automatically. The cold cathode fluorescent lamp 41 and the cold cathode ultraviolet fluorescent lamp 42 can be selectively operated. For example, if the inlet air is not contaminated with bacteria, only cold filtration or deodorizing function is required, and only the cold cathode fluorescent lamp 41 is operated. Only 42 is operated, and when the sterilization of bacteria and filtration or deodorization are required at the same time, the cold cathode fluorescent lamp 41 and the cold cathode ultraviolet fluorescent lamp 42 are operated simultaneously. By allowing the selection as described above it is possible to efficiently operate the equipment.

The inflow air that has been purified secondly through the HEPA filter 60 passes through the zeolite filter 61 to control humidity, deodorization and heavy metal purification using physical adsorption and chemical cation substitution of the zeolite filter 61. In addition, it was configured to further improve the cleanliness of the inlet air.

The inlet air, which has been thirdly purified through the zeolite filter 61, passes through the activated carbon filter 62 and is able to maintain a more complete cleanliness by applying deodorization, moisture adsorption, and the like.

Since the coating film of titanium oxide (TiO ₂ ) is formed on the copper grid portion of the various filters 60, 61, and 62, the debris of the inert bacteria sterilized by ultraviolet rays and fine particles in the inlet air purified in the previous step is removed. This minimizes the amount of fine particles filtered through the filter to extend the time to reach saturation to maximize the life of the filter.

In addition, a predetermined space is formed between the front of the HEPA filter 60 and various filters 60, 61, 62, and the inlet air is regulated within the space by adjusting the speed of the discharge fan 81. Sufficient convection allows sufficient contact for sterilization and deodorization.

The purified air passes through the activated carbon filter 62 and passes through the filter nonwoven fabric 70 containing the activated carbon component and the silver component. The air is sterilized, and harmful electromagnetic waves generated inside the air purifier are blocked to be completely purified and discharged. It is discharged to the room through the ball (82).

Convection by forced suction as described above also serves to prevent dust and bacteria particles from saturating on the mesh net of the filter and the surface of the copper ion generator 50 and inhibiting the purification function of titanium oxide (TiO ₂ ).

The energy consumption is reduced by using a cold cathode with a fluorescent lamp with a wavelength of 300 to 400 nM, which is necessary for the photocatalytic action of a UV-fluorescent lamp and a titanium oxide (TiO ₂ ) coating film, which has a wavelength of 200 to 300 nM, which sterilizes airborne bacteria. In addition, the life of the lamp was improved by 10 to 15 times to facilitate maintenance.

In addition, the suction fan 21 and the discharge fan 81 is to adjust the speed, respectively, so that the air flowing into the suction hole 22 to adjust the time to discharge to the discharge hole 82, According to the degree of contamination or required air cleanliness, it is possible to control the time of inlet air staying inside the sterilization purifier. That is, when a high level of cleanliness is required or air is severely introduced, it may be operated by lowering the rotational speed of the discharge fan 81 and the suction fan 21 so as to sufficiently sterilize and deodorize.

As described in detail above, the present invention can secure the retention space of the inlet air in the sterilization purifier, and maximize the area of copper ionization reaction and photocatalytic reaction to improve functions such as sterilization, deodorization and removal of residues. It is possible to extend the durability of various filters by allowing complete oxidation of sterilized bacteria or fine dust in the purified air.

In addition, it is possible to efficiently use the cold cathode fluorescent lamp 41 and the cold cathode ultraviolet fluorescent lamp 42, or to control the rotation speed of the suction fan 21 and the discharge fan 81 to efficiently sterilize the sterilizer. It can be used.
