Description

Air cleaning apparatus with antibacterial function {Air cleaning apparatus with antibacterial function}

The present invention relates to an air purifying device having an antibacterial function.

Air conditioners, air purifiers, or air conditioners are installed indoors in public transportation such as buses, subways, and trains, or multi-use facilities such as karaoke rooms, clubs, saunas, and commercial buildings. HEPA filters are mainly applied, and these HEPA filters are made of synthetic fibers as high-performance filters that collect fine dust and bacterial particles from the air widely used in clean rooms.

However, the dust contained in the air includes dust of 10㎛ or more that can be confirmed with the naked eye, and dust that is less than 10㎛, especially ultrafine dust (PM-2.5) of less than 2.5㎛ that is difficult to check with the naked eye, as well as various air pollutants. As a result, nitrogen oxides (NOx), hydrocarbons (HC; Hydrocarbon), carbon monoxide (CO), particulate matter (PM) containing particulates such as formaldehyde (HCHO), and dust emitted from vehicle tires However, the dust as well as various pollutants are inhaled through the respiratory system of the human body and threaten health. It was not possible to effectively block fine dust, various air pollutants, or coronavirus in public transportation or multi-use facilities.

That is, the HEPA filter can effectively catch organisms (eg, house dust mites, viruses, molds, etc.) contained in the air, but has the inconvenience of requiring frequent replacement due to the disadvantage that the organisms can proliferate, organic compounds, and harmful substances. There is a disadvantage in that there is no effect of deodorizing by oxidizing and decomposing the gas, and as a result, the polluted filter cannot emit hygienic and clean air, which is a problem in hygiene.

Therefore, users who use public transportation or multi-use facilities that are enclosed spaces wear protective masks that cover the respiratory tract as a means to prevent inhalation of dust or various air pollutants or virus infection by droplets.

However, since the wear of the above-mentioned quarantine mask must be replaced frequently, the economic burden is increased, and many people complain of discomfort due to the continuous wearing of the mask.

As such, the air purifier having an antibacterial function according to an embodiment of the present invention is installed in the air circulation path between the outdoor side and the indoor side or the indoor side, as shown in the accompanying FIGS. The first blower M1 in the purifying main body 100 is operated when it is introduced or when air from the indoor side is circulated.

Then, while the outside air is introduced through the air inlet 101 formed in the purification main body 100 according to the operation of the first blower M1, the outside air passes through the first filter unit 10. .

Then, harmful substances and fine dust contained in the outside air can be cleanly removed by the filter paper 11 made of woven artificial fibers included in the first filter unit 10, as well as contained in the outside air The virus with strong propagation power is killed while contacting the first and second antibacterial layers 13 and / or 13 'to which copper or silver nanoparticles formed on the filter paper 11 and / or carbon filter 12 are added or coated. It can.

In addition, the carbon filter 12 adhesively fixed to the filter paper 11 is a pollutant contained in the air purified by the filter paper 11 and the first and second antibacterial layers 13 and/or 13' (eg, ; Cigarette smell, pet smell, toilet smell, garbage smell, unpleasant stinky smell, and harmful smells such as formaldehyde, etc.)

Therefore, as described above, the first filter unit 10 has antibacterial and deodorizing power against not only harmful substances and fine dust contained in the air that are harmful to the human body, but also viruses with strong propagation power contained therein, and various harmful odors. It is possible to guide the air to the second filter unit 20 after first purifying the air as clean and fresh as possible.

And, the second filter unit 20 secondarily collects fine dust included in the outside air passing through the first filter unit 10 .

At this time, since the first blower M1 is installed adjacent to the acceleration region S3 inside the purification main body 100, when the first blower M1 operates, the first and second filter units The air purified by (10, 20) is quickly discharged to the second air purification area (S2) of the purification body 100, and the third and fourth filters provided in the second air purification area (S2) The units 30 and 40 can sequentially collect particulate matter (PM), which is an air pollutant, from outside air.

That is, the outside air is quickly supplied to the end surfaces of the inflow side of the third and fourth filter units 30 and 40 and enters the through cells 31 opened in the end surfaces.

Then, the outside air passes through the flow path between the cell walls 32 and collides with the plugging 33, which is the last point in the longitudinal direction, so that the particulate matter, which is a particulate component, can be purified while being oxidized and reduced by a catalytic action.

At this time, since the fourth antibacterial layer 44 is also formed on the inner and outer circumferential surfaces of the third filter unit 30, viruses that may remain in the third antibacterial layer 44 are killed, thereby public transportation However, it is possible to solve the difficulties in quarantine caused by the propagation of a highly contagious virus between people who are inevitably close to each other in the indoor space of a multi-use facility. As the purified clean air is discharged, it is possible to prevent health problems of indoor users due to inhalation of fine dust or various air pollutants.

In the above, the technical idea of the air purifier having an antibacterial function of the present invention has been described together with the accompanying drawings, but this is an exemplary description of the best embodiment of the present invention, but does not limit the present invention.
