Figure 3 is a perspective view of the loess chip far infrared and negative ions generated in the air purifying sterilizer according to an embodiment of the present invention

The present invention stores an ocher chip that generates negative ions or far infrared rays in an air purifying sterilizer in which inhaled air is sterilized and purified through irradiation of ultraviolet rays and contact with a photocatalyst, so that the negative ions or far infrared rays which are beneficial to the human body are supplied to the room to provide a photocatalyst. Sterilization and odor is removed through contact with the chip, as well as anion or far-infrared rays are increased, which relates to air purification sterilizers that generate far-infrared rays and anions that can provide beneficial air to the human body.

In general, in order to improve the efficiency and energy saving of cooling, heating, and soundproofing, the time to live in an enclosed space that is more and more blocked from the outside air is increased, and thus, various pollutants that are closely related to the internal living environment are exposed. For this reason, modern people complain of symptoms caused by internal air pollution, such as headaches, anxiety, poor concentration, and dizziness. Therefore, since indoor air is directly connected to health, various pollutants in the air that are naturally released by indoor activities And an air sterilizer that can safely remove various molds without harm to the human body is desperately needed. In order to solve this problem, Korean Air No. 460255 “Air Purification Sterilizer” has been proposed to sterilize air by contact with ultraviolet radiation and photocatalyst, but the above patent only sterilizes the introduced air, There is a problem that there is a limit because it does not include the beneficial to the human body, such as far infrared.

In addition, the living space where modern people live is gradually reduced negative ions and positive ions due to the flooding of electronic products such as air conditioners, computers, televisions. Increased cations in indoor air may adversely affect health due to metabolic disorders and weakened physiological functions.In this way, negative ions are reduced, cations are increased in indoor air, and the autonomic nervous system of the human body is strained. It is easy to catch, and far infrared ray is contained in large quantity in ocher and many products using such ocher are commercialized, and far infrared ray in ocher can activate blood cell tissue by radiation of far infrared to promote blood circulation and maintain health In addition, proven research results show that various types of far infrared radiators are excellent in promoting blood circulation, fatigue recovery, stable sleep, growth growth, heat storage and thermal effects.

An object of the present invention is to provide a storage space for a loess chip made of loess, which is irradiated with a large amount of far-infrared rays in the air purification sterilizer consisting of ultraviolet irradiation and a photocatalyst to generate negative ions, the indoor air contains a large amount of far infrared rays and anions It is to provide an air purifying sterilizer beneficial to the health of residents.

It is another object of the present invention to provide an air purifying sterilizer which can be installed in a small space by effectively sterilizing the air by reducing the flow path by a plurality of circulation plates in which the air supplied to the room is arranged in a zigzag. It is.

This object of the present invention is a suction fan in which indoor air is forced into the sterilization body through the air suction port is installed adjacent to the air suction port, the air discharge port is discharged to the other side and the sterilization body is partitioned adjacent to the suction fan The ocher chip filling unit filled with the ocher chip filled in the ocher chip filling space and formed with a plurality of air holes, the ultraviolet lamp arranged in a zigzag in the sterilizing body, and the sterilized body having the ultraviolet lamp installed are filled with a photocatalyst. The far-infrared ray according to the present invention includes a photocatalyst chip coated and filled in the space around the ultraviolet lamp, and a circulation plate disposed in a zigzag on the air flow path of the sterilizing body and arranged in a zigzag to lengthen the air flow path. It is achieved by an air purifying sterilizer in which negative ions are generated.

The air purifying sterilizer generating far-infrared rays and anions according to the present invention will be more clearly understood by the embodiments described in detail below with reference to the accompanying drawings.

The air purifying sterilizer (A) generating far-infrared rays and anions according to an embodiment of the present invention, as shown in Figure 1 to 2, the suction of the indoor air forced into the sterilization body through the air inlet (11) The fan 12 is installed adjacent to the air suction port 11 and the air discharge port 13 through which the air is discharged is filled in the sterilized main body 1 and the space partitioned adjacent to the suction fan 12. The ocher chip filling unit 2 filled with a plurality of ocher chips 21 having a plurality of flow holes therethrough, an ultraviolet lamp 3 arranged in a zigzag in the sterilizing body 1, and the ultraviolet lamp 3 The photocatalyst chip filling part 4 filled with the photocatalyst chip 41 filled on the installed sterilization body 1 and coated with a photocatalyst and filled in the space around the ultraviolet lamp 3, and the sterilization body 1 of the Zig-zag that is installed in a zigzag on the air flow path to lengthen the air flow path Comprises a circular plate (5) arranged in.

Ocher constituting the ocher chip 21, the chemical components of ocher 60-65% silica (SiO2), 5-6% iron, 10-13% alumina (AI2 O3), magnesium (Mg) and sodium (Na ) 2% or so, Kali 1.5%, lime 8% or so, and the mineral components are quartz 60 ~ 70% (changes from 40% up to 80%), feldspar and mica 10-20%, carbonate mineral 5 ~ 35 %, 2 ~ 5% silt is composed of heavy minerals such as hornblende, apatite, biotite, chlorite, citrine, verdite, garnet, ore, rutile, quartzite, cruciate, tourmaline and zircon.

 The ocher property of the ocher chip 21 is made of fine sand and contains a large amount of calcium carbonate (CaCO3), which is not easily broken and has a viscous force, and when water is added, it turns into clay. Quartz, mica and calcite are included. It is oxidized with iron and shows various colors such as yellow, purple, red, grey, and pale green.

 Ocher is a honeycomb structure with a large surface, and a large number of spaces have a multi-layer structure. In this sponge-like hole, far-infrared rays are absorbed and stored in a large amount, and radiate when heated to stimulate molecular activity of other objects. In other words, ocher absorbs solar energy for a long time and can be called 'solar storage' simply as silicon mineral.

More than 30% of the earth's crust is silicic, and loess has far-infrared emission, anion release of vitamins in the air, and in addition, the loess is filled with active yeast called karataze. Caratase yeast is a physiologically active substance that is beneficial to the human body to reduce, decompose and detoxify free radicals and peroxide lipids that cause aging. A spoonful of microorganisms contains 200 million microorganisms and contains enzymes such as diphenol oxidase, saccharase, and protease in addition to karata.

In ocher, it is well known that it is effective in preventing various adult diseases such as anti-aging, chronic fatigue by activating absorption, metabolism and blood circulation in the human body by radiating far infrared rays.

Far infrared rays emitted from ocher have the most beneficial wavelengths (5.7-10 microns) among humans among infrared rays, and this far infrared rays penetrate deep into skin (3-4cm deep) to promote cells and increase body temperature. At this time, as the body temperature rises, there is a remarkable effect on growth promotion. In particular, due to the excellent effect obtained by releasing a large amount of sweat, various toxic substances, waste products, heavy metals are released in a large amount with sweat, constitution is improved to a healthy alkalinity. In addition, because it relaxes the physical and mental tension is also effective in relieving stress caused by adult diseases. The effects of far infrared rays on living organisms have been reported for warming effect, blood promotion, metabolic function promotion, sweating promotion, analgesic effect and some other biological activities. Infrared radiation is more efficient and more efficient than visible light by F.W.Hershel in 1800. Since it was first discovered by A. Amper in 1835, the existence of electromagnetic waves with longer wavelengths than the red color of visible light is called infrared. Among these infrared electromagnetic waves, light having a property of reflection with a boundary of 4 macrons is called near infrared, and radiation having an absorption property is called far infrared. The reason why far infrared rays are good for the body is that the far infrared rays are heat energy penetrating up to 40mm in the human body as a strong heat ray. When far-infrared radiation is emitted from the soil, bacteria that cause various developments in the human body are weakened due to its thermal action, and it expands capillaries in the human body to promote blood circulation as well as to promote the production of cellular tissues. Although there are many substances that emit far infrared rays, various ceramics are made using soil as a material to emit far infrared rays. Far infrared rays emitted from the soil are the most stable radiant heat for the human body. Pottery kilns are still made of clay, and pottery bursts unless there is stable far-infrared radiation from the soil. Ocher radiates beneficial far-infrared radiation, which is absorbed by the human body, so the metabolism is smooth and the blood circulation is activated, and cell activity is active. Therefore, it is effective in preventing various adult diseases such as aging of human body, promoting metabolism and chronic fatigue. Ocher composed of such an ingredient ratio and various enzymes emits a large amount of far-infrared rays necessary for the growth of animals and plants, so it is called a living organism.

The ocher chip 21 manufactured as such ocher has a configuration in which a circular vent hole 21a is formed on a cylindrical side of about 1 cm in diameter and 1 cm in length, and the air introduced by the vent hole 21 a is in various directions. As it passes, it contains a large amount of far infrared rays and anions, and may be used as it is in this embodiment or may be used in a state in which a photocatalyst of TiO 2 is coated on the surface thereof.

The ocher chip filling unit 2 filled with the ocher chips 21 is installed adjacent to the air inlet 11, so that the air passing through the air inlet 11 and on the ocher chip filling unit 2 has a large amount of far infrared rays. Anion will be included.

The ultraviolet lamp 3 is installed in a zigzag and selected to emit radiation intensities such as near ultraviolet (UV-A315-400 nm), mid-ultraviolet (UV-B280-315 nm) and far ultraviolet (UV-C100-289 nm). In particular, it is time to apply the 253.7nm heavy ultraviolet rays, the most excellent sterilization effect ultraviolet wavelength band.

The photocatalyst chip 41 is coated with nanosilver and photocatalyst TiO2 on the surface of the photocatalyst chip so that harmful substances in the air may be decomposed by the photocatalytic reaction when ultraviolet rays are irradiated from the ultraviolet lamp 3. That is, it is formed by immersing the photocatalyst solution 1 to 5 times and then firing 1 to 5 times at room temperature or 80-100 ° C. The photocatalytic reaction refers to a reaction in which ultrafine titanium oxide having an anatase crystal structure is irradiated with light such as ultraviolet rays to generate electrons and holes on the surface while absorbing ultraviolet rays, and these electrons and holes decompose most harmful substances. Through this process, not only the contaminants and odors in the air can be removed, but also the debris can be decomposed. The theoretical configuration thereof is well known, and thus a detailed description thereof will be omitted.

The circulation plate 5 arranged in a zigzag on the air flow path of the sterilizing body 1 and arranged in a zigzag to lengthen the flow path of air effectively removes harmful viruses or odors in the air by lengthening the flow of inhaled air. I could do it. On the circulation plate 5, a plurality of holes are drilled so that air passing through is designed so as not to be overdone.

The air purifying sterilizer (A) generating far-infrared rays and anions of the present invention is a structure in which a suction fan 12 forcibly inhaling air is sucked through the air inlet 11 and discharged to the air outlet 13. The air passes through the ocher chip filling unit 2 and contacts the ocher chip 31 and includes a plurality of photocatalyst chips coated with nanosilver and a photocatalyst while passing through the photocatalyst chip filling unit 4 while containing far infrared rays and anions emitted from the ocher. The air sucked by (41) is sterilized by the ultraviolet lamp 3 and the strong oxidizing power of oxygen ions and oxygen ions generated from photocatalysts using ultraviolet light as light sources. The air outlet 13 is to be supplied back to the room again. As such, the air that is resupplied to the room is provided with beneficial air to the human body, which contains a large amount of far-infrared rays and negative ions while removing sterilization and odor.

On the other hand, through the air purifying sterilizer of the present invention configured as described above was tested whether or not inactivated infectious virus that can cause disease to human beings in the air.

There are three types of representative viruses that can be transmitted in the air. The first is a class of RNA viruses with envelopes, including the Influenza virus, which exist as bubbles and can cause acute serious illness through the respiratory tract. Viruses belonging to this group include viruses such as SARS, measles and mumps. In reality, we tested Influenza virus among the viruses belonging to this category.

Secondly, the virus chosen for this experiment is an RNA virus that has no membrane, is small in size (about 27 nm), and is robust. These viruses include Polio virus, which causes polio, and over 100 viruses that cause common cold. The presence of these viruses in the air is very likely to cause various diseases. Therefore, in this experiment, Polio virus was selected among these viruses. The 100 viruses belonging to this species are different in serology, but Polio virus was selected for testing because it is very similar to Polio virus in basic characteristics such as virus size, nucleic acid type and membrane presence. In addition, in order to arithmetically calculate the rate of virus inactivation, all three viruses used 1 million particles or the corresponding number. Attempts have been made to demonstrate that the infectious virus is inactivated in the exhaust gas when the above number of viruses are inhaled into the air purification sterilizer of the present invention. In other words, when one million infectious viruses were added, one infective virus was not detected, and a test was performed to prove whether the virus had an inactivation capacity of 99.9999% as shown in the description (this study data below) Is based on the final research report on the performance test of the air purifying sterilizer according to the present invention conducted by the Institute of Medical Science, Kangwon National University Medical School, a designated virus testing institution of the National Institute of Environmental Research.

The virus used in this study was Polio virus type III, Influenza virus (A / Johannesburg, H3N2), and Adenovirus type II, obtained from the National Institutes of Health. The titer of the virus used in the experiment was that Polio virus added 10 ⁵ plaque forming unit (PFU) to 100 ml of PBS and made it into air bubbles. Influenza virus and Adeno virus were used by injecting 10 ⁶ tissue culture infectious dose ₅₀ (TCID ₅₀ ) into 100 ml of PBS.

2) animal cell lines

For potency and infectiousness tests of Polio virus, BGM cells, a type of kidney cell line of African green monkeys, were obtained from the National Institute of Environmental Research. Cell lines used for influenza virus and Adeno virus were distributed by the National Institutes of Health. Influenza virus was used in cultured MDCK cell line, and A549 cell line was used for Adeno virus.

Three virus cell lines were cultured under the conditions of 36.5 ± 0.5 ℃, 5% CO ₂ and saturated humidity, and inoculated with virus samples after 2-3 days (80-90% growth).

3) Disinfection and sterilization of instruments and reagents

Instruments and equipment used for virus injection were essentially sterilized and sterilized at 121 ° C. for 15 minutes and 1 hour. The MDS Filter was autoclaved and sterilized at 121 ° C for 30 minutes. Scissors or tweezers were soaked in 95% ethanol and sterilized by flame before use. Glass or metal products used for virus concentration and beef extracts required for virus elution were wet sterilized at 121 ° C for 30 minutes.

Instruments and equipment that cannot be autoclaved (plastic products) are soaked in 0.1% Chlorine (pH 7.0) for 30 minutes to inactivate bacteria and viruses, then neutralize with 2% Thiosulfate solution (sodium thiosulfate) and several times with sterile distilled water. Washed and dried. The culture solution used for cell culture was filtered with a 0.2 μm sterile filter.

2. Experimental method

1) Experimental conditions

When the virus is injected into the air purifying sterilization apparatus of the present invention without any device, the injected virus is moved to another place by the flow of air so that the quantitative virus does not pass the present invention. In addition, since the injected virus may contaminate the environment, an intake duct (not shown) was installed at the air inlet 11 for safe virus spraying.

2) Virus injection and capture

Warming-up was performed for 1 hour for smooth operation before the experimental virus strain was passed through the air purifying sterilizer of the present invention. Experimental conditions of the experimental group and the control group were mounted according to the present invention and then operated. Experimental virus strain and virus diluting solution (PBS) for each experimental group and control in the present invention in operation was sprayed to the air inlet 11 of the present invention using an injector, and maintained for 10 minutes for sufficient adsorption. In this experiment, the negative control was performed first, and the negative and positive control were performed once for each of the three experimental virus strains. In addition, the experimental group of the experimental virus strain was performed three times each. After each adsorption experiment for each virus virus, all experimental equipment and laboratory interiors were disinfected.

3) Virus Elution and Concentration

After the virus injection experiment, the MDS filter was aseptically removed from the purge air outlet 13 of the present invention, soaking the MDS filter in 500 ml of Beef extract (pH9.5) and shaking for 10 minutes to release the virus as an elution solution. Put sterile magnetic bar into the eluate and mix carefully to prevent bubbles. After holding the standard of the combination type pH meter, the electrode was immersed in 0.1% chlorine solution for 1 minute, neutralized with decholoring solution, washed with 3 distilled water, and the eluate pH was titrated.

The pH was first adjusted to 7.0-7.5 using 1M HCl, and the amount of eluate was recorded using a sterile measuring cylinder.

Then, the pH was adjusted to 3.5-0.1 and mixed for 30 minutes at room temperature, and the supernatant was removed after centrifugation at 4 ° C. for 15 minutes at a rotation speed of 2500xg. 15 ml of 0.15M sodium phosphate with pH 9.0-9.5 was completely dissolved in the centrifuge container containing the precipitate, and the pH of the solution was measured and recorded. Adjust the pH of the dissolved liquid to 9.0-9.5 for 10 minutes at room temperature. It melted enough. At this time, when the precipitate was not dissolved well, the pH was adjusted to 7.5 with 1M HCl, and when completely dissolved, the pH was again titrated to 9.0 to 9.5. It was then centrifuged at 4 ° C. for 10 minutes at 9000 × g and the supernatant was taken to adjust the pH to 7.0-7.5 and used for the culture virus detection test. In order to remove microbiological contamination factors, the filter was filtered using a sterile filter (0.2 μm) in a sterile workbench, and the filter was used after pretreatment with beef extract of pH 7.0∼7.5. The supernatant thus obtained was recorded in the Virus Data Sheet at the final dose (FCSV).

4) Sample Inoculation

When inoculating the sample, a negative and positive control group was inoculated with each sample group. The results after inoculation of the samples were read after confirming the normal cell shape of the negative control group and the cytopathic effect (CPE) seen in the positive control group. Cells used for inoculation were used three to four days after passage and culture cells older than six to seven days were not used in consideration of virus sensitivity.

First, the culture medium of the cell culture vessel was discarded and washed with DMEM medium without the serum, and then, 15 ml of concentrated sample was inoculated into T-25 flask 0.75ml / T-25flask in a total of 20 flasks. The samples were evenly spread while shaking at intervals of 20 minutes while standing at 37 ° C. for 80-120 minutes for virus adsorption. After the adsorption process, DMEN medium containing 2% and 5% Fetal Calf Serum (FCS) was dispensed in each culture vessel to a total volume of 10 ml and cultured in a cell culture vessel. Cytopathic effect (CPE) was observed under a microscope for a total of 14 days, followed by daily observation for 3 days after inoculation and at 2 days interval thereafter. At least 75% cell degeneration was observed as positive.

3. Experimental Results

Samples of each experimental virus strain (Polio virus, influenza virus, adeno virus) that passed the present invention were inoculated in 20 cell culture vessels and observed continuously using an optical microscope.

BGM cells inoculated with Polio virus experimental group showed no dissociation phenomenon similar to the negative control group during all inoculations, and the cells grew well as monolayers on the bottom of the culture vessel. In the influenza virus group, cells were attached to the bottom of the culture vessel during all inoculations, like the MDCK cells of the negative control group. In addition, the Adeno virus experimental group was found to have A549 cells attached to the bottom like the negative control group. This means that there is no substance or virus that causes cytotoxicity because no substance that inhibits cell growth or kills the cells in the inoculation sample. Based on the above results, as a result of passing the Polio virus, influenza virus, and adeno virus through the air purifying sterilizer according to the present invention, it is determined that the viruses are inactivated as shown in the following table (virus research results).

4. Conclusion
