The dusts of these pollutants vary greatly depending on the particle size and the nature of the harmful effects on the human body.

Therefore, the air purification apparatus should be capable of removing not only dust on the solid particulate but also gaseous dust or contaminants in the form of microorganisms.

In general, the air purifier uses a fiber filter, an electrostatic dust collecting filter, an activated carbon adsorption filter, or the like, alone or in combination. However, there are many problems in practical application.

Such a filter method is advantageous in that the initial investment cost is low because dust is collided with a fibrous filter and the dust is collected. However, since the filter has to be exchanged from time to time, expenditure of maintenance cost becomes excessive, There is a disadvantage that it requires a contractor.

Further, it is difficult to maintain the initial process air volume due to clogging of the filter or the like, and the cleaning ability deteriorates due to the deterioration of function even after maintenance, vibration is generated, and there is a high risk of fixing due to overload of the motor. In addition, the waste filter has a problem that it is difficult to treat it as an industrial waste.

The air purifier may further include a first suction pump unit positioned between the plasma discharge unit and the water storage chamber for sucking oxygen atoms, ozone, and electrons discharged from the plasma discharge unit and discharging the oxygen atoms, ozone, and electrons to the water storage chamber have.

The air purifying apparatus according to the above feature may further include a backflow prevention device positioned between the first suction pump portion and the water storage chamber.

The air purifier may further include at least one of a second suction pump unit located between the water storage chamber and the oxygen filter passage unit and discharging the purified air of the water storage chamber to the oxygen passage filter unit have.

The air purifier according to the above feature may further include a backflow prevention device positioned between the second suction pump part and the oxygen passage filter part.

According to this feature, bacteria and pollutants contained in the air are removed by using plasma and water. Since oxygen is generated due to plasma and water, oxygen generated in the desired space is injected to increase the oxygen concentration, so that the air quality is improved and the user satisfaction is improved due to the increase of the oxygen concentration.

The plasma discharge unit 10 includes a plasma discharge plate 11 therein and has an inlet pipe 71 through which external air flows.

A first connection pipe 72 is provided between the plasma discharge unit 10 and the first suction pump unit 20 so that the plasma discharge unit 10 and the first suction pump unit 20 are connected to each other. The plasma discharge unit 10 and the first suction pump unit 20 are provided with an outlet and an inlet connected to both ends of the first connection pipe 72, respectively.

The first suction pump unit 20 functions to suck air present in the plasma discharge unit 10 and discharge the air to the water storage chamber 30. To this end, the first suction pump unit 20 is operated by a motor And an outlet of the first suction pump unit 20 is connected to a discharge pipe 73 extending into the water storage chamber 30. [

 The water storage chamber 30 stores water therein, and the discharge pipe 73 is stored in the water.

 Therefore, the air that has passed through the discharge pipe (73) is discharged into the water in the water storage chamber (30).

The second suction pump unit 40 connected to the water storage chamber 30 through the connection pipe 74 is provided with a suction pump 41 in the same manner as the first suction pump unit 20.

Thus, the air passing through the connection pipe 74 is sucked and discharged to the oxygen passage filter portion 50 side. At this time, the connection pipe 74 is connected to the upper part of the water storage chamber 30 to improve the suction efficiency of the air.

A connection pipe 75 is provided between the fourth suction pump unit 40 and the oxygen passage filter unit 50 and the fourth suction pump unit 40 and the oxygen passage filter 50 are connected to both ends of the connection pipe 75, Are connected to each other through an outlet and an inlet of the main body 40 and 50, respectively.

The air present in the water storage chamber 30 is introduced into the oxygen passage filter portion 50 through the connection pipe 75 by the operation of the second suction pump portion 40 as described above.

The oxygen passage filter unit 50 includes an oxygen passage filter 51 for passing only oxygen therethrough. Oxygen present in the air flowing into the oxygen passage filter unit 50 passes through the oxygen passage filter 51 and is discharged to the discharge pipe 76 (Eg, nitrogen) that does not pass through the oxygen passage filter 51 is discharged to the other discharge pipe 77.

At this time, the oxygen passage filter 51 may be formed of a membrane filter made of a polymer.

At this time, the discharge pipe (76) is connected to the space desired to be purified air and supplies oxygen through the discharge pipe (76) in the space.

In addition, backflow prevention devices 731 and 751, which are made of a check valve or the like, are mounted inside the discharge pipe 73 and the connection pipe 75 to prevent backflow of air, respectively.

Therefore, the air sucked into the first and second suction pump units 40 and 50 can be efficiently introduced into the water storage chamber 30 and the oxygen passage filter unit 51, thereby improving the air purification efficiency .

The operation of the air purifier having such a structure will be described.

First, when the power required for the operation of the air purifier is supplied, a plasma discharge start voltage is applied to the electrodes provided on the plasma discharge plate 11 of the plasma discharge unit 10 so that the plasma discharge plate 11 generates plasma do.

In addition, the suction pumps 21 and 41 of the first and second suction pump units 20 and 40 respectively operate to suck and discharge air in a desired direction.

When the operation of the air purification apparatus is started, the air is introduced into the plasma discharge unit 10 through the inflow pipe 71 of the plasma discharge unit 10.

Therefore, oxygen (O 2 ) in the air introduced into the plasma discharge part 10 is combined with the electrons (e - ) generated by the plasma discharge as shown in the following formula (1) electron (e -) in conjunction with the generation or other oxygen atoms (O) to ozone (O 3) to produce or two oxygen (O 2) is one of the ozone reacts (O 3) and one oxygen atom (O ).

[Formula 1]

O 2 + e - > O + O + e -

O 2 + O? O 3

O 2 + O 2 → O 3 + O

Nitrogen (N 2 ) contained in the air is converted into nitrogen (N), dinitrogen monoxide (N 2 O), two nitrogen monoxide (NO), or nitrogen oxides (N x O y ).

[Formula 2]

N 2 + e - > N + N + e -

N 2 + O - > N 2 O

N 2 O + O → 2NO

Nx + Oy → NxOy

Thus, an oxygen atom (O), electron (e -) generated in the plasma discharge parts (10) containing and ozone (O 3) and nitrogen atom (N) and nitrogen oxide (N 2 O, NO, NxOy), etc. The air that has passed through the plasma discharge unit 10 is sucked by the first suction pump unit 20 and then passes through the first suction pump unit 20 and flows through the discharge pipe 73 into the water storage chamber 30 .

Therefore, oxygen atoms O and ozone O 3 react with water (H 2 O) to generate hydroxyl groups (OH - ) and oxygen (O 2 ) through reactions such as the following formula 3, 4], the nitrogen atom (N) reacts with water (H 2 O) to generate nitrogen oxide (NO) and hydrogen (H 2 ).

[Formula 3]

O + H 2 O + e - > 2OH -

O 3 + H 2 O + e - > O 2 + 2OH -

[Formula 4]

N + H 2 O + e - > NO + H 2 + e -

As described above, the hydroxyl group (OH - ) generated by the reaction of water (H 2 O) with oxygen atom (O) or ozone (O 3 ) is dissolved in water, thereby increasing the cleaning power of water.

The contaminants and bacteria of the air discharged into the water by the operation of the first suction pump unit 20 are sterilized or greatly reduced by the action of the hydroxyl group (OH - ).

In addition, oxygen (O 2 ), nitrogen oxide (NO), and hydrogen (H 2 ) dissolved in the water are filled in the water storage chamber 30 to be discharged to the outside of the water, (Hereinafter referred to as "purified air") flows into the oxygen passage filter unit 50 in the suction operation of the second suction pump unit 40.

At this time, oxygen-pass filter 51, an oxygen (O 2) only because it is a filter for passing the oxygen of the air introduced into the oxygen-pass filter unit 50 (O 2) is oxygen-pass filter of the oxygen-pass filter (50) ( 51 to be discharged into the discharge pipe 76 and flow into the room.

On the other hand, the other substances (H 2 , NO) that have not passed through the oxygen passage filter (51) are discharged to the outside through another discharge pipe (77).

Thus, only the oxygen (O 2 ) contained in the purified air passes through the oxygen passage filter 51 of the oxygen passage filter section 50 and flows into the room, thereby increasing the oxygen concentration in the room. Accordingly, the air introduced into the room is purified air from which pollutants are removed by the action of the water storage chamber 30, and also the concentration of oxygen is increased, thereby creating a pleasant environment.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It belongs to the scope of right.
