After using the present invention, the present invention relates to an air sterilizer and an air sterilization method using moist ozone and air vortex generation that can block external leakage of residual ozone through an ozone treatment apparatus for ozone harmful to a human body.

In general, ozone is an off-white gas with three oxygen atoms. Its strong oxidizing power makes it possible to disinfect and disinfect beverages, bleach clothes, etc. In particular, it is rich in dissolved oxygen to sterilize and disinfect various bacteria and viruses. You can get it.

The ozone has a different effect on the human body depending on its concentration. When the ozone concentration satisfies the range of 0.03 to 0.05 ppm, it gives a fresh feeling to the human body. On the other hand, when the ozone concentration exceeds 0.1 ppm, it stimulates the respiratory organs or Symptoms may include coughing, headaches, and decreased lung function.

In particular, ozone refers to surplus ozone that ozone performs its original functions such as sterilization and income and is discharged to the outside. When ozone concentration of ozone concentration exceeds 0.1 ppm, when the human body is exposed to the ozone for a long time, lung function is reduced. Reduced, causing side effects that cause respiratory disease.

However, in the conventional air sterilizer for sterilizing air using ozone, since ozone remaining after sterilizing air, that is, the ozone is discharged unprotected to the outside, there is a problem that damage due to this ozone occurs.

In the present embodiment, ozone generated under high relative humidity conditions is defined as wet ozone. The concept of the wet ozone is briefly described as follows.

In general, ozone is known to inactivate because it destroys several layers of hard protein layers surrounding the spores and easily reaches the inside of the spores. The effect of high relative humidity on the treatment of dried spores with ozone gas is It is known that the environmental conditions that are unreasonable for external survival have been ended, and the state is trying to accept the external stimulus more actively, and at the same time, the condensation of ozone generated under the high relative humidity condition proceeds at the same time. It is easy to penetrate into the surface of dried Bacillus spores when the treatment method of the wet ozone sprayed in the form of mixed with fine water molecules is easier to increase the relative humidity in the air when disinfecting the gas phase using ozone.

The air sterilization apparatus includes a case 100, an ozone sterilization unit 200, an ozone supply unit 300, a water supply unit 400, an ozone treatment unit 500, and an air control unit 600.

In detail, the case 100 is a housing for sterilizing air introduced from the outside with ozone, and an inner space in which air and ozone flow is formed therein, and the inner space is divided by a plurality of partitions to form air and Provides a route for ozone

In addition, the case 100 has an air inlet through which air is introduced from the outside on one side thereof, and an air outlet 130 through which the air introduced through the air inlet is discharged to the outside is formed. Here, the air inlet of the case 100 is an inflow passage for introducing air into the case 100, the first in communication with the ozone supply unit 300, the water supply unit 400 and the ozone sterilization unit 200. The air inlet 120a and the second air inlet 120b disposed in direct communication with the ozone sterilization unit 200. And the first air inlet (120a) and the second air inlet (120b) is equipped with a pre-filter () for removing the dust flowing into the case 100.

That is, the air introduced through the first air inlet 120a is moved to the ozone sterilization unit 200 by generating wet ozone while passing through the water supply unit 400 together with the ozone generated in the ozone supply unit 300. The air introduced through the two air inlets 120b is directly moved to the ozone sterilization unit 200.

In addition, the air outlet 130 of the case 100 is a discharge passage through which the air passing through the ozone treatment unit 500 is discharged to the outside of the case 100, and a blowing fan 110 is installed for smooth flow of air. . In this embodiment, the blower fan 110 is disposed at a position opposite to the air outlet 130, but the installation position of the blower fan 110 is changed for smooth flow of air moving in the inner space of the case 100. Can be.

The ozone supply part 300 is provided at the first air inlet 120a side of the case 100. The ozone supply unit 300 is composed of an ozone generator for generating and supplying ozone, the operation of the ozone supply unit 300 is controlled by the air control unit 600. Here, the air control unit 600 detects the ozone concentration of the inner space of the case 100 in real time, and compares the detected ozone concentration with the appropriate ozone concentration, and if the detected ozone concentration is lower than the appropriate ozone concentration, the ozone supply unit ( 300 to increase the amount of ozone in the inner space of the case (100).

In addition, the water supply unit 400 is provided at the first air inlet 120a side of the case 100. The water supply unit 400 supplies water to the ozone generated by the ozone supply unit 300, so that water molecules are disposed around the ozone that has passed through the water. To this end, the water supply unit 400 receives water from a water reservoir 410 filled with water, a water supply tank 420 for supplying water to the water reservoir 410, and water from the water reservoir 410. Humidification filter 430, the humidification filter 430 is one end is contained in the water of the water reservoir 410 and the other end is disposed on the flow path of air passing through the ozone supply unit 300. As a result, ozone generated by the ozone supply unit 300 may be converted into wet ozone while passing through the humidification filter 430 together with the air introduced from the first air inlet 120a.

The ozone sterilization unit 200 is provided at the second air inlet 120b side of the case 100. The ozone sterilization unit 200 is an inner space of the case 100 in which substantial sterilization of air through wet ozone is generated. The ozone sterilization unit 200 increases the number of contact and area and contact time of harmful substances and wet ozone in the air. To this end, the ozone sterilization unit 200 is configured to smoothly collide with the wet ozone and air while forming a vortex. For example, the ozone sterilization unit 200 may be configured in the form of a cone, or may have a plurality of vortex partition walls 201 protruding in the form of protrusions, as shown in FIGS. 2 and 3. The wet moist ozone and air collide with each other more actively, and stronger sterilization can occur between the moist ozone and air. In the present embodiment, the configuration of the vortex partition wall 201 is just one embodiment that is designed to maximize the flow of air in order to form the vortex, but is not limited thereto and may be configured in various forms.

Therefore, the air passing through the first air inlet 120a, the wet ozone passing through the ozone supply unit 300 and the water supply unit 400, and the air passing through the second air inlet 120b are the ozone sterilization unit 200. In the ozone sterilization unit 200, more effective sterilization can be achieved between air and wet ozone through the vortex action.

On the other hand, the ozone treatment unit 500 is provided on the air outlet 130 side of the case 100. The ozone treatment unit 500 includes an ultraviolet lamp 510 (UV-C) for irradiating ultraviolet rays and a carbon filter 520 for removing odors and ozone. The ultraviolet lamp 510 and the carbon filter 520 sterilize the air moved from the ozone sterilizer 200 and decompose the remaining ozone.

The ozone supply unit 300, the water supply unit 400, and the ozone treatment unit 500 described above are controlled through the air control unit 600. The air control unit 600 detects the ozone concentration of the inner space of the case 100 in real time, and compares the detected ozone concentration with an appropriate ozone concentration, so that the inner space of the case 100 is maintained in an optimal sterilization state. For example, if the ozone concentration of the ozone passing through the ozone processing unit 500 is high, the air control unit 600 stops the operation of the ozone supply unit 300 to reduce the ozone concentration of the inner space of the case 100. In this case, ozone sensors 140 and 140 ′ capable of detecting ozone concentration are installed in the inner space of the case 100 and the outer space adjacent to the air outlet 130.

In this way, the present invention is to determine the ozone concentration in the case 100 according to the ozone sensor 140, 140 'to confirm the ozone concentration of the ozone zone, and the ozone sensor 140, 140' according to the confirmation result. It is possible to easily check whether residual ozone is harmful to the human body by using IT technology such as the air control unit 600 to properly control, and to effectively control air sterilization.

Detects whether the ozone concentration in the internal space is the proper ozone concentration and stops supplying the ozone in the internal space when the ozone concentration exceeds the appropriate ozone concentration (S4 '). If the ozone concentration exceeds the appropriate ozone concentration, the ozone supply to the internal space is stopped.

The air control unit 600 detects the water level of the water reservoir 410 in real time to allow continuous water supply of the water supply tank 420 to the water reservoir 410. To this end, the water reservoir 410 is provided with a water level sensor 440 that can detect the water level.

The results controlled by the air controller 600 may be displayed through the display 700. The display unit 700 may display a water supply state through the water supply unit 400, for example, a water level state of the water tank detected by the water level sensor 440, or may display an ozone state and an ozone discharge state of the case 100. Can be.

As shown in FIG. 4, the air sterilization method according to the present invention includes an ozone supply step S1, a wet ozone conversion step S2, an air sterilization step S3, and an ozone treatment step S4. .

The ozone supply step (S1) generates ozone through the ozone supply unit 300 when air is introduced through the first air inlet 120 a of the case 100. At this time, if the detected ozone concentration is the maximum ozone concentration of a level capable of perfect ozone treatment, the ozone supply unit 300 is continuously operated to generate ozone (S1 ').

The wet ozone conversion step (S2) is generated through the water supply unit 400 inside the case 100, and when the water reservoir 410 level of the water supply unit 400 sensed by the water level sensor is lower than a predetermined water level, The water supply tank 420 is operated to supply water to the water reservoir 410. At this time, the wet ozone is converted while the ozone generated in the ozone supply step passes through the humidification filter 430 together with the air introduced from the first air inlet 120a.

Air sterilization step (S3) sterilizes the air by forming a vortex in the inner space to increase the collision between the wet ozone and the air. That is, since the air introduced into the inner space of the case 100 and the wet ozone generated in the wet ozone conversion step collide frequently with each other through the vortex action, more effective sterilization may be achieved between the air and the wet ozone.

The ozone treatment step (S4) decomposes the remaining ozone after air sterilization and discharges it to the outer space of the case 100. That is, the ozone treatment step irradiates the air with ultraviolet rays through the ultraviolet lamp 510 and removes odors and ozone from the air through the carbon filter 520.

As described above, after decomposing the remaining ozone through the ultraviolet lamp 510 and the carbon filter 520, it is determined whether residual ozone exists in the air subjected to the ozone treatment through an ozone sensor in which IT technology is applied. If ozone remains, the ozone supply of the internal space is stopped. (S4 ') In addition, if ozone remains by detecting ozone remaining in the external space, the ozone supply in the case 100 is stopped.

Although the present invention has been described in detail using the preferred embodiments, the scope of the present invention is not limited to the specific embodiments, and should be interpreted by the appended claims. In addition, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.
