Description

Air purification device for adjusting the solution injection amount corresponding to the amount of the fine particles}

The present invention relates to an air purifying apparatus using a solution spray, and more particularly, to an air purifying apparatus for adjusting a solution spray amount corresponding to an amount of fine dust.

Generally, the air purifier that discharges clean air after removing fine dust, various harmful gases, bacteria, mold, viruses, etc. Various functions such as disease prevention will be provided.

Representative methods of such air purifiers can be classified into electrostatic precipitating and filter filtration.

Here, the filter filtration formula is a method of purifying air by using a filter having a fine structure so that small particles pass through the small particles, and foreign matters having large particles are filtered. .

In addition, the electrostatic precipitating method is a method of purifying air by using an electrostatic precipitating plate in which static electricity is generated so that foreign matters contained in the air are attached, so there is no need to replace the filter because there is no filter. There was a disadvantage that the capacity is reduced and the ability to remove dust.

On the other hand, recently, a wet type air cleaner which performs air cleaning using water has been developed. Such a conventional wet-type air purifier completely removes foreign substances contained in external air due to a phenomenon in which the purification power decreases rapidly due to foreign substances contained in the water when the foreign substances contained in the external air are purified once passed through the injected water. There was a problem that could not be cleaned.

Here, the polluted air may be air of the atmosphere including fine dust made naturally or artificially. The upper housing 102 may be supported by the lower portion of the upper housing 102 in contact with the upper portion of the row housing 101.

The polluted air suction unit 103 may suck the polluted air flowing from the outside into the air purification apparatus 100. To this end, the contaminated air suction unit 103 has a suction fan 103a at one end, and the contaminated air flows from the suction fan 103a to the other end communicating with the inlet 104a of the contaminated air flow path unit 104. Suction spaces can be formed.

That is, the suction fan 103a is driven so that the polluted air flowing from the outside is sucked into the suction space inside the polluted air suction part 103, and the sucked polluted air passes through the suction space and the inlet of the polluted air flow path part 104. May flow into 104a.

The polluted air flow path part 104 may be a flow path through which the sucked polluted air flows. The contaminated air flow path 104 may have a rectangular parallelepiped shape in which an upper portion and a lower portion are open. The polluted air flow path part 104 communicates with the other end of the polluted air intake part 103 so that the polluted air sucked by the polluted air intake part 103 flows into the contaminated air flow path part 104. It can be provided at one end.

In addition, the contaminated air flow path 104 may have an outlet 104b at the other end in communication with one end of the purge air collecting part 109 and the purified air discharged from the contaminated air flow path 104.

That is, the solution is injected by the solution injection unit 105 in the open upper portion of the polluted air flow path 104, and the polluted air introduced into the inlet 104a is injected while the polluted air flow path 104 flows. Fine dust is adsorbed and purified in the solution, and the purified purge air may flow out to the outlet 104b. In addition, the solution in which the fine dust is adsorbed may pass through the open lower portion of the contaminated air flow path 104 and fall below the contaminated air flow path 104.

On the other hand, the contaminated air flow path 104 is a guide member 104c inclined at a predetermined angle with respect to the flow direction from the inlet 104a to the outlet 104b to control the flow path through which the contaminated air introduced into the flow flows. It may be provided.

The guide member 104c may be a plurality of protrusions protruding from at least one inner wall of the contaminated air flow path part 104. In one embodiment, the guide member 104c may be a protrusion having a rectangular plate shape having a predetermined thickness.

The rotating member 104'c may be provided in a screw shape or a fan shape.

Due to the configuration of the present invention, the contaminated air flows inside the contaminated air flow path part 104 ′, thereby increasing the flow time. For this reason, the amount of time that the fine dust contained in the contaminated air can be adsorbed with the solution injected by the solution injection unit 105 increases, so that the amount of fine dust adsorption may increase.

Referring back to FIGS. 1 to 5, the solution injection unit 105 may inject a solution toward the polluted air flowing in the polluted air flow path 104.

At this time, the injection direction control unit 105c may adjust the injection direction so that the solution is injected into the width of the flow path of the contaminated air flow path (104). That is, the injection direction control unit 105c may constantly adjust the injection direction so that the solution is injected from one end to the other end of the flow path width.

At this time, the injection direction control unit 105c may increase the control speed of the injection direction as the flow rate of the contaminated air is faster, and may decrease the control speed of the injection direction as the flow rate of the contaminated air is slower.

The injection amount adjusting unit 105d according to another embodiment may adjust the injection amount of the solution injection unit 105 in response to the amount of dust for each particle size of fine dust included in the contaminated air.

Specifically, the injection amount adjusting unit 105d according to another embodiment may increase the nozzle width of the injection nozzle 105b so that the injection amount is increased as the particle size of the largest amount of dust among the amount of dust for each particle size of the fine dust is small.

On the contrary, the injection amount adjusting unit 105d according to another embodiment may reduce the nozzle width of the injection nozzle 105b so that the injection amount is smaller as the particle size of the largest amount of dust among the amount of dust for each particle size of the fine dust is larger.

In order to control the injection amount of the above-described solution, the inside of the contaminated air intake unit 103 may be provided with a fine dust measurement unit for measuring the amount of dust for each particle size of the fine dust.

The solution blocking part 106 encloses a space between the solution injection part 105 and the contaminated air flow path part 104 so that the solution injected from the solution injection part 105 does not fall out of the upper portion of the contaminated air flow path part 104. It can be formed so that.

To this end, the solution blocking unit 106 may be formed in a rectangular band shape with the top and bottom open.

The solution storage unit 107 may store a solution in which fine dust is adsorbed. In detail, the solution storage unit 107 may store the solution that is injected from the solution injection unit 105 and dropped through the contaminated air flow path unit 104 therein.

To this end, the solution reservoir 107 may be formed in a rectangular parallelepiped shape.

Meanwhile, the solution reservoir 107 may be formed by penetrating the second through hole 107a on one side thereof, and the second through hole 107a may be connected to the second moving tube 108b connected to the solution moving part 108. .

The solution stored in the solution reservoir 107 may flow out to the second through hole 107a by the solution moving unit 108.

The solution moving unit 108 may move the solution stored in the solution storage unit 107 to the solution injection unit 105. To this end, the solution moving part 108 sucks the solution stored in the solution storage part 107 through the second moving pipe 108b connected to the second through hole 107a, and the agent connected to the first through hole 105a '. The solution sucked through the first moving tube 108a may be moved to the solution injection unit 105.

In one embodiment, the solution moving unit 108 may be a motor driven to move the solution.

The purge air collecting unit 109 may collect and purge the purified purge air by adsorbing fine dust from the polluted air to the solution and discharge the purified air. To this end, the purifying air collecting unit 109 is provided with a collecting fan 109a at the other end, and the purifying air flows from the collecting fan 109a to one end communicating with the outlet 104b of the contaminated air flow path 104.

The filtration control unit 102 'measures the transparency of the filter 101'a of the rotating solution filtration unit 101' and converts the transparency measured according to the rotational speed of the filter 101'a into a filter use degree. It may be calculated, and it may be determined whether to replace the filter 101'a based on the filter usage.

To this end, the filtration control unit 102 'may irradiate light to the filter 101'a through an optical sensor, and measure the amount of light scattered by the filter 101'a with transparency. Thereafter, the filtration control unit 102 ′ may calculate the degree of use of the filter by applying a conversion coefficient according to the rotation amount of the filter 101 ′ a to the transparency.

Here, the conversion coefficient may be a coefficient for converting the filter use degree by lowering the measured transparency as the rotational speed of the filter 101'a increases.

For example, the filtration control unit 102 'can measure the transparency indicating that the filter 101'a is more opaque as the rotational speed is higher, even though the amount of fine dust filtered through the filter 101'a is the same. have. In this case, the filtration control unit 102 ′ may calculate the filter utilization by applying a conversion coefficient that lowers the transparency to the transparency as the transparency measured from the filter 101 ′ a having a high rotation speed is increased.

In other words, even when the same transparency is measured, the filtration control unit 102 'can calculate the filter usage of the filter 101'a having a faster rotational speed than the filter usage of the filter 101'a having a slower rotational speed. have.

Thereafter, the filtration control unit 102 ′ may transmit the filter replacement request signal to the outside through communication when the filter usage exceeds the preset reference filter usage.
