The air purifier 100 of the present invention includes a housing 110, a mechanical filter 120, an electric filter 130, and a sterilizing deodorization filter 140. [

The housing 110 is coupled to the rear portion of the image imaging device 200 or provided inside the rear surface to form a main body of the air purifier 100 and to provide an inlet and an outlet path for indoor air for purifying. Includes an inlet (111) and an outlet (112).

The inlet port 111 is provided in the lower portion of the housing 110 to introduce indoor air containing particulate pollutants floating in the lower portion of the indoor space having a larger specific gravity than air, In portion of the substrate.

The outlet port 112 is formed in an opening on both sides of the housing 110 and forms the end of the internal flow path of the room air purified and discharged to the outside.

It is needless to say that the position and shape of the inlet 111 and the outlet are not limited to the above, and that a well-known structure may be used as long as the indoor air can be easily sucked and exhausted.

The mechanical filter 120 is provided on the inner flow path formed from the inlet 111 to the outlet 112 as a filter cloth made of a porous fiber material so as to filter dust having a relatively large particle size, And may be provided in plurality as needed.

In addition, the mechanical filter 120 may include a mesh-type mesh and a zeolite-based adsorbent to be filled in the mesh, so as to remove gaseous contaminants.

The electric filter 130 is provided at the rear end of the internal flow path of the mechanical filter 120 to remove fine dust contained in the room air primarily filtered at the mechanical filter 120. The electric filter 130 includes a discharge electrode 131, (132) and a gap adjusting member (133).

The discharge electrode 131 is provided in a crossing net shape or a net shape formed in one direction so as to cross the internal flow path to provide a flow path of the room air and a current of high voltage is applied to the discharge electrode 132, . In addition, a plurality of discharge needles 131a are provided along the discharge electrode 131 to form an unequal electric field due to the shape of the discharge electrode 131 together with the unequal electric field formed by the voltage difference.

The discharge needle 131a may be formed in a rod shape or a needle shape so as to form an unequal electric field due to the magnetic loss of the discharge electrode 131 to which a high voltage is applied.

The dust collecting electrode 132 is provided in a direction facing the discharge electrode 131 in a grounded state as described above to form an unequal electric field with the discharge electrode 131 to which a high voltage is applied. And a plurality of air gaps 132a for forming an unequal electric field due to the shape and for providing a flow path of the indoor air.

The gap 132a is provided at a position corresponding to the position of the discharge needle 131a to form an uneven electric field by forming a tip shape of a part of the dust collecting electrode 132 similar to the discharge needle 131a .

A discharge phenomenon appears around the discharge needle 131a and the gap 132a due to an unequal electric field formed by the discharge electrode 131 and the dust collecting electrode 132. As a result, fine dust contained in the introduced indoor air is charged unipolarly Moves to the dust collecting pole 132 and is collected by the dust collecting pole 132, thereby filtering the secondary particulate pollutant.

The distance between the discharge electrode 131 and the dust collecting electrode 132 is generally 1 mm when a voltage of 1,000 V is applied to the discharge electrode 131. When the interval is formed to be less than or equal to the interval, the amount of generated ozone (O 3) increases with the generation of anions in proportion to the density in the interval. When the interval is formed more than that, the discharge amount according to the unequilibrium electric field decreases, .

Therefore, the interval adjusting member 133 may be disposed in the direction of the dust collecting pole 132 or the dust collecting pole 132 in the direction of the discharging electrode 132. In this case, (131) to adjust the gap. The gap adjusting member 133 may be provided on the discharge electrode 131 and the dust collecting electrode 132 to maintain the distance between the mechanical filter 120 and the sterilizing and deodorizing filter 140 to be uniform. And the dust collecting pole 132, respectively.

In the present embodiment, the plurality of solenoid valves are applied to the corner of the discharge electrode 131 or the dust collecting electrode 132, but the technical idea of the present invention is not limited thereto, It is needless to say that well known components such as a belt and pulley, a rack and a pinion, a gear and a chain, and a ball screw, which are suitable for adjusting the distance between the discharge electrode 131 and the dust collecting pole 132, may be used.

The sterilizing and deodorizing filter 140 is provided at the rear end of the electric filter 130 in the inner flow path and is provided for sterilizing and deodorizing indoor air filtered by the mechanical filter 120 and the electric filter 130, An ultraviolet lamp 141 and a reflector 142.

The ultraviolet lamp 141 is provided at the center of the inner flow path for removing bacteria or microorganisms contained in the indoor air and irradiates ultraviolet rays toward the flow path of indoor air.

The reflection plate 142 is provided at the rear end of the inner flow path with respect to the ultraviolet lamp 141 so that ultraviolet rays reflected by the reflected ultraviolet rays are irradiated to the indoor air again and is coated with an aluminum material having a good reflectance . At this time, the reflection plate 142 may be coated with the photocatalyst 142a for antibacterial and deodorization. The coating of the aluminum coating and the photocatalyst 142a is provided on the surface of the dust collector 132 facing the ultraviolet lamp 141 to serve as the reflector 142.

The photocatalyst 142a is generally made of TiO2 and the ultraviolet rays having a wavelength (< 400nm) having an energy of a band gap or more are irradiated to the surface of the photocatalyst 142a. The transition occurs to the conduction band, and electrons and holes are diffused to the surface of the photocatalyst 142a as holes (H +) are generated in the valence band. Through this process, an OH radical is generated to decompose organic substances on the surface of the photocatalyst 142a.

OH Radical and O2-Radical generated by the photocatalyst 142a stick to the bacterial cell membrane to oxidize and decompose, thereby destroying the cell membrane and exhibiting a sterilizing and deodorizing effect.

In summary, the indoor air containing the particulate pollutants is discharged through the mechanical filter 120 and the electrical filter 130 to the particulate pollutants, sterilized and deodorized through the sterilization and deodorization filter 140, . At this time, the gap between the discharge electrode 131 and the dust collecting electrode 132 is adjusted by the electric filter 130 for filtering the fine dust, so that a uniform unequal electric field can be formed. Accordingly, A fine dust filtering effect can be obtained.

Hereinafter, the principle of dust collection of the electric filter 130 will be described, and the structure of the air cleaning apparatus 100 of the present invention will be described.

4 is a partial cross-sectional view illustrating an air purifying process of the air purifying apparatus according to an embodiment of the present invention. FIG. 3 is a cross- 5 is a diagram illustrating a configuration of a control unit according to an embodiment of the present invention.

3, the air purifier 100 of the present invention has a structure in which the fine dust introduced through the discharge of the discharge electrode 131 provided at the upstream side of the flow path of the indoor air is anionized, (132). &Lt; / RTI &gt;

The fine dust collecting principle of the electric filter 130 will be briefly described. The fine dust collecting principle consists of mechanisms such as formation of discharge, charging of fine dust, movement of charged particles, and collection at the dust collecting pole 132.

A direct current high voltage (about 20 KV) is applied between the discharge electrode 131 and the dust collecting electrode 132 to form a unidirectional unequal electric field between the discharge electrode 131 and the dust collecting electrode 132. The intensity of this unequal electric field decreases from the discharge electrode 131 toward the dust collecting electrode 132.

At this time, the gas molecules around the electrode connected by the high voltage are electrically broken by the discharge phenomenon, and fluorescence is generated around the electrode by the electron emission of the gas. The strong electric field around the discharge electrode 131 is generated by the free electron And discharges one more free electron. These free electrons collide with gas molecules in a chain and generate a large number of positive ions and free electrons. The generated free electrons are adsorbed on gas molecules to produce gas molecules having anions. The gas ions thus formed collide with and attract the fine dusts to electrically attract the fine dust particles and move toward the dust collecting electrode 132 by an electrical attraction force (about 300 times of gravity) , The fine dust can be removed.

Referring to FIG. 4, the air purifier 100 of the present invention has a structure in which indoor air filtered through a gap of a discharge electrode 131 having a net- The particulate matter contained in the indoor air is anionized and the fine dust is collected by the dust collecting pole 132 and the secondarily filtered indoor air passes through the air gap 132a of the dust collecting pole 132 And then discharged out of the electric filter 130 through the filter 130.

At this time, the position of the gap 132a is provided so as to correspond to the position of the discharge electrode 131 or the discharge needle 131a, and the room air is refracted by the flow path and the time for staying in the electric filter 130 is increased, The effect of the ring 130 can be doubled. That is, the clearance of the discharge electrode 131 and the position of the gap 132a are staggered with respect to the flow direction of the room air, so that the residence time of the room air can be increased, thereby increasing the filtering effect.

The fine dust contained in the room air is formed in the direction of the air gap 132a from the discharge needle 131a so that the shape of the discharge needle 131a and the gap 132a in addition to the unequal electric field due to the voltage difference It is possible to obtain a collecting effect that is doubled by an unequal electric field caused by an increased discharge effect.

The uneven electric field formed by the shape of the discharge needle 131a and the gap 132a is dependent on the magnitude of the voltage applied to the discharge electrode 131 and interlocked. The applied voltage may not be constant. As a result, the generated amount of discharge and the effect of collecting fine dust may not be constant.

Therefore, in the electric filter 130 of the air cleaning apparatus 100 of the present embodiment, the gap 131 is provided in the discharge electrode 131 or the dust collecting pole 132, so that the interval between the discharge electrode 131 and the dust collector 132 It is possible to obtain a constant discharge amount and a dust collecting effect.

The gap adjusting member 133 may be provided as a solenoid valve and installed in the discharge electrode 131 or the dust collecting electrode 132 to move the discharge electrode 131 or the dust collecting electrode 132 along the inner flow path The distance between the discharge electrode 131 and the dust collecting electrode 132 can be adjusted by moving the discharge electrode 131 on the basis of the discharge electrode 131 or the discharge electrode 131 on the basis of the dust collecting electrode 132, The interval can be adjusted by moving.

Here, the controlled interval may be controlled through the controller 150 based on the amount of fine dust collected or accumulated according to the applied voltage, or based on the generated negative ions.

5, the controller 150 includes a voltage sensor 151, a pressure sensor 152, and an anion sensor 153 to perform the functions as described above. The distance between the discharge electrode 131 and the dust collecting electrode 132 can be adjusted.

The voltage sensor 151 may measure the amount of applied voltage and provide the measured value to the controller 150. The pressure sensor 152 may measure the amount of fine dust accumulated relative to the pressure of the dust collector 132 set at the time of installation It is possible to compare the pressure of the dust collecting pole 132 at present and provide the measured value to the controller 150. [ Further, it is also possible to provide a measurement value for any one of the discharge amount of the discharge, the amount of anion generated through the discharge, and the amount of ozone through the negative ion sensor 153 so that when the measured value exceeds the error range, The member 133 can be moved to adjust the dust collecting efficiency according to the discharge amount.

In addition, a position sensor 154 for measuring the distance between the discharge electrode 121 and the dust collecting electrode 131 together with the sensors 151, 152, 153 may be provided to improve the accuracy of the gap adjustment.

In summary, the electric filter 130 of the air purifier 100 of the present invention includes a voltage sensor 151 for measuring the pressure applied to the dust collecting electrode 132 or the discharge electrode 131, an accumulation amount of the collected fine dust And the distance between the discharge electrode 131 and the dust collecting electrode 132 is determined through an anion sensor for measuring an amount of generated negative ions or an amount of ozone, 131 and the dust collecting pole 132, it is possible to realize and maintain the filtering efficiency of the desired fine dust.
