It is a partial cross-sectional view showing the driving state of the device.

Referring to Figure 1, the air cleaning device 100 according to a preferred embodiment of the present invention, the housing 110 and the air (A) accommodated in the inner space 112 of the housing 110 through a predetermined flow path. A blowing fan 120 that blows air to flow along, and the air (A) flowing in the inner space 112 by the blowing fan 120 are installed to pass through, and the collecting net 130 is rotated around a central axis. , It may include a collection liquid supply unit 140 for supplying the collection liquid (Lc) to the collection network (130).

First, the housing 110 is a device that provides a space for purifying air (A).

As shown in FIG. 1, the housing 110 includes an inner space 112 filled with a collection liquid Lc at a predetermined level, and air outside the housing 110 (hereinafter, referred to as'outside'). A supply pipe 114 for guiding (A) to the inner space 112 and a discharge pipe 116 for guiding the air (A) of the inner space 112 to the outside may be provided. The exterior of the housing 110 is preferably an indoor space in which the air cleaning device 100 is installed, but is not limited thereto. In addition, when the exterior of the housing 110 refers to an indoor space, the external air A refers to indoor air of an indoor space in which the air purifier 100 is installed.

The shape of the housing 100 is not particularly limited. For example, the housing 100 may have a cylindrical shape.

In the inner space 112, the formation of a swirling airflow (S1) and a vortex (V1) to be described later, and to install various components provided in the air cleaning device 100, such as a blower fan 120 and a collecting net 130. It is formed in the interior of the housing 110 so as to have a volume of an appropriate size. The collection liquid Lc may be filled in the inner space 112 by a predetermined level.

The collecting liquid Lc is a liquid substance for collecting dust and other contaminants contained in the air A supplied to the inner space 112 by the supply pipe 114 to be described later and removing it from the air A. Corresponds to the filter. The kind of liquid substance that can be used as such a collecting liquid Lc is not particularly limited. For example, the collection liquid Lc may be any one of water, an aqueous solution in which a sterilizing substance capable of removing bacteria or a collecting substance capable of collecting a predetermined contaminant is added to water.

It is preferable that the housing 110 is provided so that such a collecting liquid Lc can be exchanged or recharged. For example, as shown in Figure 1, the housing 110, the upper surface is opened and the lower housing (110a) in which the collection liquid (Lc) is filled by a predetermined level, and the lower surface is open and hooked, other couplings It may be composed of an upper housing 110b or the like that is detachably coupled to the lower housing 110a by a method. O-rings and other sealing members (not shown) may be installed at the interface where the lower housing 110a and the upper housing 110b are in contact with each other. .

The supply pipe 114 communicates with the inner space 112 so as to guide external air (A) to the inner space 112. Therefore, when the air (A) accommodated in the internal space 112 is discharged to the outside by the blowing fan 120 to be described later, and a negative pressure acts on the supply pipe 114, the external air A through the supply pipe 114 It may be supplied to the inner space 112.

The structure of the supply pipe 114 is not particularly limited. For example, as shown in FIG. 1, the supply pipe 114 has an outlet 114b through which air (A) introduced from the outside is discharged through an inlet 114a is lower than the water surface of the collecting liquid Lc. It may be coupled to the circumferential surface of the housing 110 so as to communicate with the inner space 112. Then, the external air (A) may be supplied into the water of the collecting liquid (Lc) through the supply pipe (114). Through this, the supply pipe 114 increases the contact area and contact time between the air (A) supplied through the supply pipe 114 and the collection liquid (Lc), thereby improving the air purification efficiency of the air cleaning device 100. I can.

In addition, the supply pipe 114 is preferably installed so that the swirling air flow (S1) is formed in the inner space (112). For example, as shown in FIG. 2, the supply pipe 114 may be coupled to the circumferential surface of the housing 110 so as to extend along the tangential direction of the inner space 112. Then, as shown in FIG. 3, in the inner space 112, the air (A) supplied to the inner space 112 through the supply pipe 114 rotates along the inner circumferential surface of the inner space 112 (S1). ) Is formed.

In addition, as shown in FIG. 3, the collected liquid Lc filled in the inner space 112 is rotated by the rotational force transmitted from the swirling airflow S1 to form a vortex V1. As described above, the collected liquid Lc forming the vortex V1 forms a cross-sectional shape of a'U' shape in which the water level rises toward the inner circumferential surface of the inner space 112 by centrifugal force. Then, on the inner circumferential surface of the inner space 112, the contact between the collecting liquid Lc and the air A, which respectively rotates along the inner circumferential surface of the inner space 112, is actively made. Therefore, the collecting liquid Lc rotating along the inner circumferential surface of the inner space 112 collects dust and other contaminants contained in the air A and removes it from the air A, thereby primarily removing the air A. Can be purified.

The discharge pipe 116 communicates with the inner space 112 to guide the air (A) accommodated in the inner space 112 to the outside. For example, as shown in FIG. 1, the discharge pipe 116 has an inlet 116a through which the air A accommodated in the inner space 112 flows in from the outlet 114b of the supply pipe 114 in the direction of gravity. The housing 110 is spaced apart by a predetermined interval in the opposite direction, and the outlet 116b through which the air (A) introduced into the inlet 116a is discharged penetrates the bottom surface of the inner space 112 and extends to the outside. It can be coupled to the lower portion of the, that is, the lower housing (110a).

When the discharge pipe 116 is provided in this way, as shown in FIG. 3, the air A accommodated in the inner space 112 may be discharged to the outside through the discharge pipe 116. By the way, the inlet 116a of the discharge pipe 116 is located in the opposite direction of the gravity direction, that is, in the upper direction than the outlet 114b of the supply pipe 114, and is located in the inner space 112 by the supply pipe 114. The formed swirling airflow S1 has a shape of a swirling upward airflow. Then, as shown in FIG. 3, the air A accommodated in the inner space 112 rises toward the upper end of the inner space 112 by the swirling airflow S1. In order to reinforce the swirling airflow S1, the housing 110 preferably has a conical shape whose diameter gradually decreases toward the top, but is not limited thereto.

On the other hand, it is preferable that the inlet 116a of the discharge pipe 116 is separated from the water surface of the collecting liquid Lc filled in the inner space 112 by a predetermined distance in a direction opposite to the direction of gravity. Through this, it is possible to prevent the collecting liquid Lc filled in the inner space 112 from flowing into the discharge pipe 116.

Next, the blowing fan 120 is a member that provides a driving force necessary to blow the air (A) accommodated in the inner space (112).

The blowing fan 120 is preferably configured as an axial fan in the axial direction capable of blowing air (A) in the axial direction, but is not limited thereto.

The blowing fan 120 is installed to be able to blow air so that the air A accommodated in the inner space 112 flows along a predetermined flow path. For example, the blowing fan 120 may be installed to blow air (A) accommodated in the inner space 112 toward the inlet 116 of the discharge pipe 116. To this end, as shown in FIG. 3, the blowing fan 120 is spaced apart from the inlet 116a of the discharge pipe 116 by a predetermined interval in the direction opposite to the direction of gravity, and is concentric with the discharge pipe 116. It may be installed in the inner space 112. That is, the blowing fan 120 may be installed in the inner space 112 so that the rotation axis 122 of the blowing fan 120 and the central axis of the discharge pipe 116 are located in a straight line. This blowing fan 120 sucks the air (A) of the internal space (112), more specifically, the air (A) that has risen to the upper end of the internal space (112) by the swirling air flow (S1), and the discharge pipe (116) The air may be blown toward and the air (A) blown by the blowing fan 120 may be discharged to the outside through the discharge pipe 116. Then, when the air contained in the inner space 112 is discharged to the outside by using the blowing fan 120 as described above, the negative pressure acts on the inner space 112 and the supply pipe 114, so that the external air A is supplied to the supply pipe 114 It may be resupplied to the inner space 112 through ).

However, the air (A) supplied to the inner space 112 through the supply pipe 114 forms a swirling airflow (S1), but some of the air (A) can flow in a state separated from the swirling airflow (S1). have. Due to this, some of the air (Ad) of the air (A) separated from the turning airflow (S1) flows along the outer circumferential surface of the discharge pipe 116 and passes through the discharge pipe 116 in a state that contains dust and other contaminants as it is. When discharged to the outside, there is a concern that the air purification efficiency of the air cleaning device 100 may be deteriorated.

To solve this, the blowing fan 120 allows some of the air (A) blown by the blowing fan 120 to flow into the discharge pipe 116 and the rest of the air flows along the outer peripheral surface of the discharge pipe 116. Can be arranged to do. As shown in FIG. 3, when the housing 110 is provided so that a swirling airflow S1 rising along the inner circumferential surface of the inner space 112 is formed, some of the air A separated from the swirling airflow S1 The air (Ad) of may rise along the outer peripheral surface of the discharge pipe (116). In this case, the blowing fan 120 discharges a part (Ae) of the air blown by the blowing fan 120 to the outside through the discharge pipe 116 and at the same time, the remaining part (Ac) is discharged from the discharge pipe. It can be provided to descend along the outer circumferential surface of (116). Then, the air (Ac) blown by the blowing fan 120 to flow (fall) along the outer peripheral surface of the discharge pipe 116 (hereinafter referred to as'departure prevention air (Ac)') and the discharge pipe 116 The air Ad (hereinafter, referred to as'path departure air (Ad)') separated from the turning airflow S1 so as to flow (rise) along the outer circumferential surface proceeds in opposite directions to each other. Accordingly, the departure prevention air (Ac) may push the path departure air (Ad) to prevent further flow toward the inlet (116a) of the discharge pipe (116). The departure prevention air (Ac) and the path departure air (Ad) pushed out by the departure prevention air (Ac) pass through the space between the discharge pipe 116 and the inner circumferential surface of the inner space 112 and merge into the swirling airflow (S1). . Accordingly, the departure-preventing air Ac may function as an air curtain that blocks direct flow of the path departure air Ad into the discharge pipe 116 in an unpurified state. Through this, the blowing fan 120 can improve the air purification efficiency of the air cleaning device 100 by minimizing the flow rate of the air A discharged to the outside without being filtered by the collected liquid Lc. .

The method of installing the blower fan 120 so that the above-described air curtain is formed is not particularly limited. For example, as shown in FIG. 3, the blowing fan 120 may have a diameter larger than the discharge pipe 116 by a predetermined ratio. Then, the air (A) blown from the central region facing the discharge pipe 116 of the entire region of the blowing fan 120 can be mainly discharged to the outside through the discharge pipe 116, and The air (A) blown from the outer area not facing each other mainly flows along the outer circumferential surface of the discharge pipe 116 to form the above-described departure preventing air (Ac).

The driving source of the blowing fan 120 is not particularly limited. For example, as shown in FIG. 3, in the blowing fan 120, the rotation shaft 122 may be axially coupled with the driving motor 150 to be rotationally driven by the driving motor 150. The drive motor 120 is preferably installed in the inner space 112, but is not limited thereto. That is, the driving motor 120 may be installed outside the housing 110. It is preferable that the driving motor 150 rotates the blower fan 120 at a speed of 1500 RPM to 2000 RPM, but is not limited thereto.

On the other hand, when a blower fan, a pump, or other blower (not shown) is additionally installed in the discharge pipe 116 or a duct connected to the discharge pipe 116, the blower fan 120 is air (A) in the inner space 112 It can be automatically rotated by the airflow formed while being discharged to the outside by such a blower. Therefore, in this case, the drive motor 150 may be omitted. In addition, an auxiliary blower (not shown) may be installed in the supply pipe 114 to supply external air (A) to the inner space 112 by assisting the blowing fan 120.

FIG. 4 is a plan view of the collection net shown in FIG. 1, FIG. 5 is a partially enlarged view of the collection net shown in FIG. 4, and FIG. 6 is a view showing the contact between air and a collection liquid in a blowing fan and a collection network. to be.

Next, the collecting net 130 is a device that induces contact between the air (A) and the collecting liquid (Lc).

As shown in FIG. 3, the central axis of the collecting net 130 may be axially coupled with the rotational shaft 122 of the blowing fan 120. Then, the collecting net 130 may be rotated together with the blowing fan 120 and formed concentric with the blowing fan 120 and the discharge pipe 116. Instead of being axially coupled with the rotation shaft 122 of the blowing fan 120, the collecting net 130 may be axially coupled with a driving motor (not shown) other than the above-described driving motor 150, and may be independently rotated. . For convenience of explanation, hereinafter, it is assumed that the central axis of the collecting net 130 is axially coupled with the rotating shaft 122 of the blowing fan 120 so that the blowing fan 120 and the collecting net 130 are rotated together. It will be described the present invention.

The installation position of the collection net 130 is not particularly limited. For example, as shown in FIG. 3, the collecting net 130 collects liquid particles Lcp of the collecting liquid Lc formed by scattering the collecting liquid Lc on the vortex V1 by centrifugal force. It may be installed at a predetermined position so as to reach at least a portion of the network 130. Then, the collecting network 130 may receive the collecting liquid Lc not only by the collecting liquid supply unit 140 to be described later, but also through the swirling airflow S1. Accordingly, the collection liquid supply unit 140 may be omitted depending on the installation location of the collection network 130 and other environmental conditions.

The number of installations of the collection net 130 is not particularly limited. For example, as shown in FIG. 3, the collection net 130 is at least axially coupled with the rotational shaft 122 of the blowing fan 120 so that it is located farther from the discharge pipe 116 than the blowing fan 120. One first collecting net 131 and at least one second collecting net 132 axially coupled with the rotation shaft 122 of the blowing fan 120 so as to be located closer to the discharge pipe 116 than the blowing fan 120 ) And the like. In this case, the first collecting net 131 is disposed between the upper end of the inner space 112 and the blowing fan 120, and the second collecting net 132 is between the blowing fan 112 and the discharge port 116. Is placed in

In addition, when a plurality of the first collection nets 131 and the second collection nets 132 are respectively installed, the first collection nets 131 and the second collection nets 132 are It is installed at predetermined intervals in the direction, and may be individually shaft-coupled with the rotation shaft 122.

When the first collecting net 131 and the second collecting net 132 are installed in this way, the air A sucked by the blowing fan 120 is converted into the first collecting net 131, the blowing fan 120, and the second collecting net 131. It passes through the collection network 132 in sequence.

The shape of the collecting net 130 is not particularly limited. For example, as shown in FIG. 4, the collection net 130 may have a disk shape. In addition, the collecting net 130 preferably has the same diameter as the blowing fan 120 or smaller by a predetermined ratio than the blowing fan 120, but is not limited thereto. That is, the collecting net 130 may have a larger diameter than the blowing fan 120. In addition, an insertion hole 133 capable of inserting and fixing the rotation shaft 122 may be formed at the center of the collection net 130. Then, by inserting and fixing the rotation shaft 122 in the insertion hole 133, the collecting net 130 may be axially coupled with the rotation shaft 122.

As shown in FIG. 5, the collecting net 130 may have a net structure in which a plurality of nets 134 are formed. These areolaes 134 have a size and shape through which air (A) can pass.

It is preferable that the collecting net 130 is formed of a material having good wettability. In addition, the collection net 130 may be formed of a flexible material that can be changed in shape. For example, as shown in FIG. 5, the collecting net 130 may be a woven fabric formed by woven warp 135 and weft 136 made of fibers. In this case, the collecting net 130 may be disposed in a sagging state by gravity when it is not rotated, and may be rotated in a state unfolded in a disc shape by centrifugal force when it is rotated. However, the present invention is not limited thereto, and the collecting net 130 may be formed to maintain a constant shape by resisting gravity even when it is not rotated. For example, the collecting net 130 may be formed to be integrated by processing synthetic resins, metals, and other materials having high rigidity using a processing method such as injection or casting.

Next, the collecting liquid supply unit 140 is a device that supplies the collecting liquid Lc to the collecting network 130.

The configuration of the collecting liquid supply unit 140 is not particularly limited. For example, as shown in FIG. 3, the collecting liquid supply unit 140 includes a collecting liquid pump 142 for pumping the collecting liquid Lc filled in the inner space 112 and a collecting liquid pump 142 A collecting liquid supply pipe 144 or the like for supplying the collecting liquid Lc pumped by) to a predetermined position of the collecting network 130 may be provided.

The collecting liquid pump 142 is installed so that at least a part of the collecting liquid Lc is immersed in the collecting liquid Lc filled in the inner space 112 so as to be able to pump the collecting liquid Lc. The type of pump that can be used as the collecting liquid pump 142 is not particularly limited, and the collecting liquid pump 142 may be configured as a conventional pump used to pump a liquid substance.

The collecting liquid pump 142 is preferably driven when the collecting net 130 is rotationally driven, but is not limited thereto.

The collecting liquid supply pipe 144 is connected to the discharge port of the collecting liquid pump 142 and extends the collecting liquid Lc delivered from the collecting liquid pump 142 to a position capable of discharging toward a predetermined position of the collecting network 130 do. For example, as shown in FIG. 3, when the first and second collecting nets 131 and 132 are installed, the collecting liquid supply pipe 144 is air sucked by the blowing fan 120 (A) It may be installed so as to be able to discharge the collecting liquid Lc toward the center of the first collecting net 131 that arrives first. In addition, a spray nozzle 146 for spraying the collection liquid Lc toward the center of the first collection net 131 may be mounted at an end of the collection liquid supply pipe 144.

Hereinafter, with reference to the drawings, a description will be made of an aspect in which the air (A) is purified in the collection net (130).

First, the driving motor 150 and the collecting liquid pump 142 are driven. Then, the blowing fan 120 and the collecting net 130 are driven to rotate together, and the collecting liquid Lc is sprayed toward the center of the first collecting net 131 from the spray nozzle 146. Accordingly, as shown in FIG. 3, a swirling airflow S1 and a vortex V1 are formed in the inner space 112, and the air A rising along the swirling airflow S1 is caused by the vortex V1. The rotating collection liquid Lc is actively in contact with the inner circumferential surface of the inner space 112. In such a contact process, dust and other contaminants contained in the air A are collected in the collecting liquid Lc rotated by the vortex V1, so that the air A is primarily purified.

In a process in which the collecting liquid Lc is rotated by the swirling air current S1, some of the collecting liquid Lc on the vortex V1 is scattered toward the blowing fan 120 and the collecting net 130. Then, liquid particles Lcp of the collecting liquid Lc scattered by the swirling air current S1 are supplied to the blowing fan 120 and the collecting net 130, and in particular, the central part of the first collecting net 131 The collection liquid Lc sprayed from the spray nozzle 146 is additionally supplied to the spray nozzle 146.

Next, as shown in FIG. 6, the collecting liquid Lc supplied to the first collecting net 131 from the swirling airflow S1 and the spray nozzle 146 is rotated when the first collecting net 131 is rotated. It is distributed over the entire area of the first collecting net 131 while spreading from the center of the first collecting net 131 toward the outer periphery by the acting centrifugal force. Then, the first collecting net 131 is rotated in a wet state by the collecting liquid Lc as a whole. However, the first collecting net 131 is rapidly rotated at a speed of 1500 RPM to 2000 RPM along the blowing fan 120. Accordingly, the collecting liquid Lc rotating along the first collecting net 131 in a wet state of the first collecting net 131 reaches the first collecting net 131 by the suction force of the blowing fan 120. It is actively in contact with the formed air (A). In addition, as shown in FIG. 5, the collection liquid Lc is formed by scattering from the first collection network 131 by the centrifugal force acting on the first collection network 131, or The liquid particles (Lcp) of the collected liquid (Lc) formed when the reached collection liquid (Lc) collides with the mesh structure of the first collection network (131) is also air (A) reaching the first collection network (131) and Active contact. In this contact process, dust and other contaminants contained in the air A are collected in the collecting liquid Lc, so that the air A is secondarily purified.

Meanwhile, the air A secondaryly purified by the first collecting net 131 passes through the meshes 134 of the first collecting net 131 and moves toward the blowing fan 120. In addition, some of the collection liquid Lc supplied to the first collection net 131 is scattered toward the inner circumferential surface of the internal space 112 by centrifugal force and then falls by gravity to be recharged in the internal space 112, The remaining part of the collecting liquid Lc supplied to the first collecting net 131 is moved toward the blowing fan 120 by the suction force of the blowing fan 120.

Thereafter, as shown in FIG. 6, the swirling air current S1 and the collecting liquid Lc supplied from the first collecting net 131 to the blowing fan 120 are applied when the blowing fan 120 rotates. It is distributed over the entire area of the blowing fan 120 while spreading from the center of the blowing fan 120 toward the outside by the centrifugal force. Then, the blowing fan 120 is rotated in a wet state by the collecting liquid Lc as a whole. Accordingly, the collecting liquid Lc that rapidly rotates along the blowing fan 120 while wet the blowing fan 120 is in active contact with the air A that has reached the blowing fan 120. In addition, the collecting liquid Lc is formed by scattering from the blowing fan 120 by the centrifugal force acting on the blowing fan 120 or the collecting liquid Lc reaching the blowing fan 120 is transferred to the blowing fan 120 and Liquid particles Lcp of the collecting liquid Lc formed while colliding are also actively contacted with the air A reaching the blowing fan 120. In this contact process, dust and other contaminants contained in the air A are collected in the collecting liquid Lc, and thus the air A is thirdly purified.

On the other hand, the air (A) that is thirdly purified by the blowing fan 120 is blown toward the discharge pipe 116 by the blowing fan 120. In addition, some of the collected liquid Lc supplied to the blowing fan 120 is scattered toward the inner circumferential surface of the inner space 112 by centrifugal force and then falls by gravity to be recharged in the inner space 112, and the blowing fan The remaining part of the collected liquid Lc supplied to the 120 is moved toward the discharge pipe 116 together with the air A blown by the blowing fan 120.

Next, as shown in FIG. 6, the collecting liquid Lc supplied from the swirling airflow S1 and the blowing fan 120 to the second collecting net 132 is, when the second collecting net 132 rotates. It is distributed over the entire area of the second collecting net 132 while spreading out from the center of the second collecting net 132 toward the outer periphery by the acting centrifugal force. By the way, the second collection net 132 is rapidly rotated along the blowing fan 120 at a speed of 1500 RPM to 2000 RPM. Accordingly, the collecting liquid Lc rotating along the second collecting net 132 in a wet state of the second collecting net 132 is air blown to the second collecting net 132 by the blowing fan 120. It is in active contact with (A). In addition, as shown in FIG. 5, the collection liquid Lc is formed by scattering from the second collection network 132 by the centrifugal force acting on the second collection network 132 or is formed by the second collection network 132. The liquid particles (Lcp) of the collected liquid (Lc) formed while the reached collection liquid (Lc) collides with the mesh structure of the second collection network (132) and air blown to the second collection network (132) (A) and Contacted. In this contact process, dust and other contaminants contained in the air A are collected in the collecting liquid Lc, so that the air A is quaternarily purified.

On the other hand, the air (A) that has been fourthly purified by the second collection net 132 passes through the meshes 134 of the second collection net 132 and is blown toward the discharge pipe 116, so that the discharge pipe 116 It is discharged to the outside through. However, most of the collection liquid Lc supplied to the first collection net 131 and the blowing fan 120 is caused by the centrifugal force to the inner circumferential surface of the inner space 112 in the first collection net 131 and the blowing fan 120. The bar is scattered toward the side and recharged in the inner space 112, and in the second collection net 132, only a small amount of residual collected liquid Lc that was not recovered using centrifugal force from the first collection net 131 and the blowing fan 120 Delivered. For this reason, in the second collection net 132, the collection liquid Lc is scattered toward the inner circumferential surface of the internal space 112 by centrifugal force, and a collection action of the collected liquid recharged in the internal space 112 mainly occurs, and the collection liquid ( The air purification action by Lc) occurs relatively small. Accordingly, according to the second collection network 132, the remaining collection liquid Lc that cannot be recovered from the first collection network 131 and the blowing fan 120 can be recovered, and the second collection network 132 is a collection liquid. (Lc) may function as a blocking network or filter for blocking discharge to the outside through the discharge pipe 116 in a liquid state. Through this, the air cleaning device 100 maintains a constant amount of the collected liquid Lc within a predetermined reference range even if it is used for a long time, so that the exchange period of the collected liquid Lc can be lengthened, and the collection liquid ( As Lc) is discharged to the outside in a liquid state, bacterial contamination and other hygiene problems can be prevented.

In the conventional solid filter type air cleaning device, it is difficult to remove ultrafine dust having a remarkably small particle size, harmful substances such as mold and pollen, and harmful gases due to the characteristics of the HEPA filter. On the other hand, the air cleaning device 100 includes ultra-fine dust having a remarkably small particle size, harmful substances such as mold and pollen, and water-soluble harmful gases such as _{sulfurous acid gas (S0 2} ) and ammonia gas (NH _{3 ).} The air A is purified by using the collecting liquid Lc, which is composed of water capable of collecting various contaminants, as a liquid filter, and thus air purification efficiency can be improved compared to a conventional air purifier. In addition, since the collection liquid Lc is composed of water, it may have a larger purification capacity and a lower price than the HEPA filter. Accordingly, the air cleaning apparatus 100 can improve the convenience of maintenance by extending the filter replacement period, and reduce the cost required for maintenance by lowering the filter replacement cost.

In general, the liquid has a property of promoting natural vaporization as the flow rate of the gas in contact with it is fast, the contact with the gas is increased, or the atmospheric pressure is decreased. By the way, in the case of the air cleaning device 100, the collecting liquid Lc not only comes into contact with the swirling airflow S1 rapidly accelerated by the blowing fan 120, but also the blowing fan 120 or the collecting net 130 It is in contact with the air (A) passing through the blowing fan 120 or the collecting net 130 at high speed while rotating rapidly along the line. For this reason, in the inner space 112, natural vaporization of water contained in the collecting liquid Lc is actively generated by the air A. The water vapor generated by the natural vaporization of water is mixed with the air A, and the air Ae may be discharged to the outside through the discharge port 116 in a humidified state by the mixed water vapor. Accordingly, the air cleaning device 100 may be utilized as an air washer having both an air purification function and an air humidification function.

On the other hand, the collecting liquid Lc supplied to the blowing fan 120 and the collecting net 130 is generated by the centrifugal force acting when the blowing fan 120 and the collecting net 130 rotate. It is separated from (130) and recharged in the inner space (112). That is, the collecting liquid Lc is not accumulated in the blowing fan 120 and the collecting net 130 for a long time, but is collected again after wetting the blowing fan 120 and the collecting net 130 for a while. For this reason, the blowing fan 120 and the collecting net 130 may be repeatedly cleaned by the swirling air current S1 or the new collecting liquid Lc continuously supplied by the collecting liquid supply unit Lc. Through this, the air cleaning device 100 may prevent the proliferation of bacteria due to the accumulation of the collecting liquid Lc in the blowing fan 120 and the collecting net 130 for a long time.

7 is a diagram illustrating a state in which the air cleaning device and the air curtain device shown in FIG. 1 are connected.

Referring to FIG. 7, the discharge port 116 of the air cleaning device 100 may be connected to an air curtain device 500 installed at an entrance of various facilities and an air supply line 510. Then, the air Ae discharged from the air cleaning device 100 is supplied to the air curtain device 500, so that the air curtain that blocks outside air from the outdoor space from entering the indoor space is purified by the air cleaning device 100. It can be formed using clean air (Ae). Through this, the air cleaning device 100 may improve the quality of the air inside the indoor space of the facility in which the air curtain device 500 is installed.

In addition to the use of grafting the air cleaning device 100 with the air curtain device 500 as described above, the air cleaning device 100 may be used for various purposes. That is, the air purifier 100 constitutes a variety of products such as air purifiers, outdoor air supplies, humidifiers, and air cleaners that can be used in various fields such as residential facilities, commercial facilities, industrial facilities, road facilities, transportation, and electronic products. Can be used to

FIG. 8 is a partial cross-sectional view showing a schematic configuration of an air cleaning apparatus in which a collecting net is installed according to a second form, and FIG. 9 is a view for explaining a method of covering the collecting net shown in FIG. 8 on a blowing fan, and FIG. 10 Is a partial cross-sectional view showing a driving state of the air cleaning device shown in FIG. 8.

Referring to FIG. 8, the air cleaning device 100 may include a collecting net 137 having a cover shape surrounding the outside of the blowing fan 120. The collecting net 137 is preferably installed in the housing 110 instead of the collecting net 130 described above, but is not limited thereto. That is, the collecting net 137 may be installed in the housing 110 in addition to the collecting net 130.

The structure of the collecting network 137 is not particularly limited. For example, the collecting net 137 has a net structure in which nets through which air A can pass, and has a predetermined volume to accommodate the blades 124 of the blowing fan 120 therein. Have. Here, the blades 124 are coupled to the rotation shaft 122 at a predetermined angular interval, and while being rotated along the rotation shaft 122, the air contained in the inner space 112 may be blown along a predetermined flow path. .

In addition, at least a portion of the collecting net 137 may be provided to be elastically deformable so as to easily cover the blades 124. For example, as shown in FIG. 9, the collecting net 137 may include an insertion hole 137a that is elastically deformable on one side so as to increase or decrease the diameter.

9 and 10, such a collecting net 137 elastically deforms the insertion hole 137a so that the blades 124 of the blowing fan 120 can pass through the insertion hole 137a. In the open state, the collecting net 137 is covered with the blowing fan 120 so that the blades 124 are accommodated in the collecting net 137, and the inner circumferential surface of the elastically restored insertion hole 137a is the blowing fan 120 Install so as to contact the outer circumferential surface of the rotating shaft 122 of ). Then, the inner circumferential surface of the insertion groove 137a elastically presses the outer circumferential surface of the rotation shaft 122, through which the collecting net 137 can be axially coupled to the rotation shaft 122 while receiving the blades 124. . Then, the blowing fan 120 is disposed in a state in which the blades 124 are accommodated in the collecting net 137, and when the blowing fan 120 is driven by the driving motor 150, the collecting net 137 is a blowing fan. It is driven to rotate along 120.

When the collecting net 137 having a cover shape is installed in this way, in the collecting net 137 and the blowing fan 120, the air ( A) is purified and humidified. However, when the collecting net 137 is provided in the form of a cover, the collecting net 137 is driven in a tightly coupled state with the blowing fan 120 compared to the case where the collecting net 130 is provided in a disk shape. , The collection net 137 may purify and humidify the air (A) reaching the blowing fan 120 in a state integral with the blowing fan 120.

By the way, as shown in FIG. 10, the collecting liquid Lc sprayed from the spray nozzle 146 and the particles Lcp of the collecting liquid Lc scattered from the swirling airflow S1 are the blowing fan 120 It is mainly supplied to the front of the front and the front of the collecting net 137 in close contact therewith. Accordingly, in the front of the blowing fan 120 and the front of the collecting net 137, purifying and humidifying action of the air A by contact between the collecting liquid Lc and the air A occurs actively. In addition, the collecting liquid Lc supplied to the front of the blowing fan 120 and the collecting net 137 is scattered toward the inner circumferential surface of the inner space 112 by centrifugal force, and the blowing fan 120 and the collecting net 137 By being recovered from, it is rejoined into the collection liquid Lc accommodated in the inner space 112.

On the other hand, at the rear of the blowing fan 120 and the rear of the collecting net 137, only the remaining collected liquid Lc that has been recovered by centrifugal force from the front of the blowing fan 120 and the front of the collecting net 137 is limited. Delivered. Accordingly, in the rear of the blowing fan 120 and the rear of the collecting net 137, the purifying and humidifying action of the air (A) is relatively weak, and the collection action of the collected liquid (Lc) mainly occurs by centrifugal force. It is done. Accordingly, the air (A) blown from the blowing fan 120 can be discharged to the outside through the discharge pipe 116 in a state in which the collected liquid (Lc) (or particles (Lcp)) is completely recovered, and the air ( It is possible to prevent the occurrence of bacterial growth and other hygiene problems due to the discharge of the liquid collection liquid (Lc) (or particles (Lcp)) along A) to the outside.

Fig. 11 is a partial cross-sectional view showing a schematic configuration of an air purifier equipped with a collecting net according to a third aspect.

Referring to FIG. 11, the collection net 138 may have a cover shape that selectively surrounds any one of the blades 124 of the blowing fan 120. In this case, the collection net 138 may be provided with the same number as the number of blades 124 and may be individually covered on each blade 124.

The structure of the trapping nets 138 is not particularly limited. For example, each of the collecting nets 138 has a net structure in which nets through which air (A) can pass, and selectively accommodates any one of the blades 124 of the blowing fan 120 therein. It has a pre-determined volume to be able to do so.

In addition, each of the collecting nets 138 may be provided to be elastically deformable at least in part so as to easily cover the blades 124. For example, each of the collecting nets 138 may include an insertion hole 138a that is elastically deformable on one side so as to increase or decrease the diameter.

As shown in FIG. 10, in a state in which the insertion hole 138a is elastically deformed so that any one of the blades 124 can pass through the insertion hole 138a, each of the collecting nets 138 is opened, Covering the collecting net 138 on any one of the blades 124 so that any one of the blades 124 is accommodated in the collecting net 138, the inner circumferential surface of the elastically restored insertion hole 138a It is installed so as to contact the outer peripheral surface of one blade (124). Then, the inner circumferential surface of the insertion groove 138a elastically presses the outer circumferential surface of the one of the blades 124, through which the collecting nets 138 receive the one of the blades 124, respectively. It may be coupled to any one blade 124.

When the collecting nets 138 are installed in this way, compared to the case where the collecting net 137 is installed to cover the entire blades 124 (see FIG. 10), the collecting net 138 is provided with the blowing fan 120 It can be driven to rotate in a more tightly coupled state.

Since the air (A) is purified and humidified in the collection net 138 and the blowing fan 120 is similar to the case where the collection net 138 is provided to cover the entire blowing fan 120 (Fig. 10) , Detailed description of this will be omitted.

FIG. 12 is a partial cross-sectional view showing a schematic configuration of an air purifier equipped with a blowing fan according to a second form, and FIG. 13 is a view showing a state in which air and a collecting liquid are in contact with the blowing fan shown in FIG.

12 and 13, a mesh-shaped pattern 126 (hereinafter, referred to as a “net mesh pattern 126”) may be formed on an outer surface of each of the blades 124 of the blowing fan 120. The mesh pattern 126 is preferably formed on both the front and rear surfaces of the blades 124, but is not limited thereto. In the case where the mesh pattern 126 is formed on the outer surfaces of the blades 124 as described above, the above-described collecting nets 130, 137, and 138 are preferably omitted, but the present invention is not limited thereto. That is, the above-described collecting nets 130, 137, 138 may be installed even when the net pattern 126 is formed on the outer surfaces of the blades 124. Hereinafter, the mesh pattern 126 will be described based on the case where the above-described collection networks 130, 137, and 138 are omitted.

The method of forming the mesh pattern 126 is not particularly limited. For example, the mesh pattern 126 may be formed by performing a marking operation on the outer surfaces of each of the blades 124 using a laser processing machine.

The shape of the mesh pattern 126 is not particularly limited. For example, as shown in FIG. 12, the mesh pattern 126 may be formed to form a lattice shape. In this case, the mesh pattern 126 is preferably formed to protrude by a predetermined height so as to have a protrusion shape on the outer surface of each of the blades 124, but is not limited thereto.

The formation position of the mesh pattern 126 is not particularly limited. For example, the mesh pattern 126 may be formed on the front and rear surfaces of the blade 124, respectively. However, the present invention is not limited thereto, and the mesh pattern 126 may be formed on any one of the front and rear surfaces of the blade 124.

12 and 13, in the case of forming the mesh pattern 126 on the outer surface of each of the blades 124 while omitting the collecting nets 130, 137, 138, the blowing fan 120 ) Is installed at a predetermined position in the inner space 112 so that the liquid particles Lcp of the collecting liquid Lc scattered by the swirling air current S1 reach at least a portion of the mesh pattern 126, and are collected. The spray nozzle 146 of the liquid supply unit 140 is installed to spray the collecting liquid Lc toward the front surface of the blades 124. Then, the collecting liquid Lc sprayed from the spray nozzle 146 and the particles Lcp of the collecting liquid Lc scattered from the swirling airflow S1 are mainly supplied to the front surfaces of the blades 124. The collected liquid Lc supplied to the front surface of the blades 124 is spread from the center of the blowing fan 120 toward the outside by the centrifugal force acting when the blowing fan 120 rotates. It is distributed over the entire area of the front. Then, the blowing fan 120 is rotated in a state in which the front surfaces of the blades 124 are entirely wet with the collecting liquid Lc. This is understood, the collected liquid Lc rotating along the blowing fan 120 while wet the front of the blades 124 is the air (A) reaching the blades 124 by the suction force of the blowing fan 120 ) And is in active contact. In addition, the collecting liquid Lc is formed by scattering from the blades 124 by the centrifugal force acting on the blades 124 or the collecting liquid Lc reaching the front surface of the blades 124 is formed in the mesh pattern 126 The particles Lcp of the collecting liquid Lc formed while colliding with) are also actively contacted with the air A reaching the front surface of the blades 124. In this contact process, the air A is purified and humidified. In addition, the collecting liquid Lc supplied to the front surface of the blades 124 is scattered toward the inner circumferential surface of the inner space 112 by centrifugal force and is recovered from the blades 124, so that the collecting liquid contained in the inner space 112 ( Rejoined in Lc).

On the other hand, to the rear surface of the blades 124, only the remaining collected liquid Lc, which has been recovered by centrifugal force from the front surface of the blades 124, is limitedly transmitted. Accordingly, at the rear surface of the blades 124, the purifying and humidifying action of the air A is relatively weak, and the collection action of the collected liquid Lc by centrifugal force occurs mainly.

14 is a partial cross-sectional view showing a schematic configuration of an air cleaning device according to a second embodiment of the present invention, and FIG. 15 is a partial cross-sectional view showing a driving state of the air cleaning device shown in FIG. 14.

In the air cleaning apparatus 200 according to the second embodiment of the present invention, the structure of the housing 210 and the installation positions of the blowing fan 220 and the collecting net 230 have been changed. It differs from the device 100. Hereinafter, the air cleaning device 200 will be described centering on these differences, and descriptions of the contents overlapping with the air cleaning device 100 will be omitted or briefly described.

As shown in FIG. 14, the supply pipe 214 has an outlet 214b through which air (A) introduced from the outside through an inlet 214a is discharged is the water surface of the collected liquid Lc filled in the inner space 212 It may be coupled to the circumferential surface of the housing 210 so as to communicate with the inner space 212 at a higher position than that. Then, the external air A may be supplied to the space above the water surface of the collecting liquid Lc through the supply pipe 214. In addition, in the discharge pipe 216, the inlet 216a through which the air of the inner space A is introduced is lower than the outlet 214b of the supply pipe 214, and the collecting liquid Lc filled in the inner space 212 The housing 210 so that the outlet 216b through which the air (A) introduced into the inlet 216a is discharged extends to the outside through the ceiling surface of the inner space 212 while being positioned higher than the water surface of the Can be combined on the top of.

In addition, the blowing fan 220 is installed to be able to blow air so that the air A accommodated in the inner space 212 flows along a predetermined flow path. For example, the blowing fan 220 may be installed to blow air (A) accommodated in the inner space 210 toward the inlet 216a of the outside air discharge pipe 216. To this end, the blowing fan 220 is located between the water surface of the collecting liquid Lc filled in the inner space 212 and the inlet 216a of the discharge pipe 216, and is concentric with the discharge pipe 216. It may be installed in the inner space 212. The rotation shaft 220 of the blower fan 220 may be axially coupled to the inner space 212 or the driving motor 250 installed outside. Accordingly, the blowing fan 220 may be rotationally driven by the driving motor 250.

The collecting net 230 includes a first collecting net 231 installed between the water surface of the collecting liquid Lc filled in the inner space 212 and the blowing fan 220, the blowing fan 220, and the discharge pipe ( A second collecting net 233 installed between the inlets 216a of 216 may be provided. It is preferable that the central axis of the first collecting net 231 and the central axis of the second collecting net 233 are axially coupled to the rotational shaft 222 of the blowing fan 220, respectively. However, the present invention is not limited thereto, and the collection network 230 may be axially coupled with a driving motor (not shown) other than the above-described driving motor 250 and may be independently rotated. For convenience of explanation, hereinafter, based on the case where the central axis of the collecting net 230 is axially coupled with the rotating shaft 222 of the blowing fan 220 and the blowing fan 220 and the collecting net 230 are driven together The present invention will be described.

As shown in FIG. 15, when the driving motor 250 and the collecting liquid pump 242 of the collecting liquid supply unit 240 are driven, the air ( A) is discharged to the outside through the discharge pipe 216, and external air (A) is transferred to the internal space 212 through the supply pipe 214 by the negative pressure applied to the internal space 212 and the supply pipe 214. Resupplied. As such, the air (A) resupplied to the inner space 212 forms a swirling air flow S2 that descends while turning the inner space 212 along the inner circumferential surface, and the internal space ( A vortex V2 is formed in the collecting liquid Lc filled in 212). Accordingly, the air (A) and the collecting liquid (Lc) turning along the inner circumferential surface of the inner space 212 are actively contacted with each other so that dust and other contaminants contained in the air (A) are collected in the collecting liquid (Lc), By inducing the natural vaporization of water contained in the collected liquid Lc, the air A is primarily purified and humidified.

In addition, the air (A) descending to the lower end of the inner space 212 along the swirling air current (S2) is a blowing fan ( 220). Then, the air A raised toward the blowing fan 220 sequentially passes through the first collecting net 231, the blowing fan 220, and the second collecting net 233. This air (A) is supplied to the first collecting net 231, the blowing fan 220 and the second collecting net 233 by the swirling airflow (S2) and the spray nozzle 246 of the collecting liquid supply pipe 244. After being further purified and humidified by the collection liquid Lc, it is discharged to the outside through the discharge pipe 216.

Meanwhile, the air cleaning device 200 has been described as having a collecting net 230 having a disk shape, but is not limited thereto. That is, the air cleaning device 200, instead of or in addition to the collecting net 230, can be covered all over the blades of the blowing fan 220 or can be selectively covered on any one of the blades. It may also include a cover-type collection net.

In addition, a mesh pattern having the same mesh structure as the above-described mesh pattern 126 may be formed on the outer surfaces of each of the blades of the blowing fan 220. In addition, when the collecting net 230 is omitted and a net pattern is formed on the outer surfaces of each of the blades, the blowing fan 230 is a liquid particle of the collecting liquid Lc scattered by the swirling air current S2. It is installed at a predetermined position in the inner space 212 so that the field Lcp reaches at least a portion of the mesh pattern, and the spray nozzle 246 of the collecting liquid supply unit 240 faces the front of the blades. ) Can be installed to spray.

16 is a partial cross-sectional view showing a schematic configuration of an air cleaning apparatus according to a third embodiment of the present invention.

In the air cleaning apparatus 300 according to the third embodiment of the present invention, the structure of the housing 310 and the installation position of the blowing fan 320 and the collecting net 330 have been changed. It differs from the devices 100 and 200. Hereinafter, the air cleaning device 300 will be described centering on these differences, and the description will be omitted or briefly described for the content overlapping with the air cleaning devices 100 and 200 described above.

First, the housing 310 includes an internal space 312 filled with a collection liquid Lc to a predetermined level, a supply port 314 for guiding the external air A to the internal space 312, and an internal A discharge port 316 for guiding the air A in the space 312 to the outside may be provided. The housing 310 preferably has a cylindrical shape, but is not limited thereto.

The supply port 314 may be formed by opening the upper surface of the housing 310 to communicate with the inner space 312. The number of supply ports 314 is not particularly limited, and at least one supply port 314 may be opened in the housing 310.

The discharge port 316 is formed by opening the circumferential surface of the housing 310 so as to communicate with the inner space 312, and may be formed to be positioned at a lower height than the supply port 314. The number of the discharge ports 316 is not particularly limited, and at least one discharge port 316 may be opened in the housing 310.

Next, the blowing fan 320 is installed to be capable of blowing air so as to flow the air A accommodated in the inner space 312 along a predetermined flow path. For example, the blowing fan 320 may be installed to blow air (A) accommodated in the internal space 312 toward the water surface of the collecting liquid Lc filled in the internal space 312. To this end, the blowing fan 320 is installed in the inner space 312 so as to be located at a height between the supply port 314 and the discharge port 316, and may be installed to face the water surface of the collecting liquid Lc. Preferably, the blowing fan 320 may be installed such that the rotation shaft 322 and the supply port 314 of the blowing fan 320 are concentric. The rotation shaft 322 is axially coupled to the inner space 312 or the driving motor 350 installed outside, through which the blowing fan 320 may be rotationally driven by the driving motor 350. The blowing fan 320 may blow air (A) accommodated in the inner space 312 toward the water surface of the collecting liquid (Lc).

Next, the collecting net 330 is axially coupled with the rotation shaft 322 of the blowing fan 320 so that it can be rotated along the blowing fan 320. However, the present invention is not limited thereto, and the collection network 330 may be shaft-coupled with a driving motor (not shown) other than the above-described driving motor 350 and may be independently rotated. For convenience of explanation, the present invention will be described below based on a case where the central axis of the collecting net 330 is axially coupled with the rotational shaft 322 of the blowing fan 320.

The installation position of the collection net 330 is not particularly limited. For example, the collection net 330 may be installed in the inner space 312 so as to be positioned between the supply port 314 and the blowing fan 320. However, the present invention is not limited thereto, and instead of between the supply port 314 and the blowing fan 320, a collecting net 330 is installed between the blowing fan 320 and the water surface of the collecting liquid Lc, or the blowing fan 320 Another collection net may be additionally installed between the and the water surface of the collection liquid Lc.

The collecting liquid supply unit 340 collects a collecting liquid pump 342 that pumps the collecting liquid Lc filled in the internal space 312 and the collecting liquid Lc pumped by the collecting liquid pump 342 A collection liquid supply pipe 344 that discharges toward a predetermined position of the net 330 may be provided. The predetermined position of the collection network 330 is not particularly limited. For example, the collection liquid supply pipe 344 may be provided to discharge the collection liquid Lc pumped by the collection liquid pump 342 toward the center of the collection network 330. In addition, a spray nozzle 346 for spraying the collection liquid Lc toward the center of the collection net 330 may be mounted at the end of the collection liquid supply pipe 344.

Hereinafter, a description will be made of an aspect in which the air A is purified by the collection net 330.

First, the driving motor 350 and the collecting liquid pump 342 are driven. Then, while the blowing fan 320 and the collecting net 330 are driven to rotate, the collecting liquid Lc is injected from the spray nozzle 346 toward the center of the collecting net 330.

The collecting liquid Lc supplied from the spray nozzle 346 to the collecting net 330 is spread out from the center of the collecting net 330 toward the outer periphery by the centrifugal force acting when the collecting net 330 rotates. It is distributed over the entire area of 330. Then, the collecting net 330 is rotated in a wet state by the collecting liquid Lc as a whole. For this reason, the collecting liquid Lc rotating along the collecting net 330 in a wet state of the collecting net 330 is air (A) reaching the collecting net 330 by the suction force of the blowing fan 320 and Active contact. In addition, the collecting liquid Lc is formed by scattering from the collecting net 330 by the centrifugal force acting on the collecting net 330, or the collecting liquid Lc reaching the collecting net 330 is formed by the centrifugal force acting on the collecting net 330. Liquid particles Lcp of the collecting liquid Lc formed while colliding with the mesh structure are also actively contacted with the air A that has reached the collecting network 330. In this contact process, dust and other contaminants contained in the air (A) are collected in the collection liquid (Lc), and the natural vaporization of the water contained in the collection liquid (Lc) is induced, thereby primarily purifying the air (A). And humidified.

On the other hand, the air (A) primarily purified by the collecting net 330 passes through the meshes of the collecting net 330 and moves toward the blowing fan 320. In addition, some of the collecting liquid Lc supplied to the collecting net 330 is scattered toward the inner circumferential surface of the inner space 312 by centrifugal force and then dropped by gravity to be recharged in the inner space 312, and The remaining part of the collected liquid Lc supplied to the 330 is moved toward the blowing fan 320 by the suction force of the blowing fan 320.

Next, the collecting liquid Lc supplied from the collecting net 330 to the blowing fan 320 is spread from the center of the blowing fan 320 toward the outside by the centrifugal force acting upon the rotation of the blowing fan 320. It is distributed over the entire area of the blowing fan 320 while going. Then, the blowing fan 320 is rotated in a wet state by the collecting liquid Lc as a whole. Accordingly, the collecting liquid Lc that rapidly rotates along the blowing fan 320 while wet the blowing fan 320 is in active contact with the air A that has reached the blowing fan 320. In addition, the collecting liquid Lc is formed by scattering from the blowing fan 320 by the centrifugal force acting on the blowing fan 320, or the collecting liquid Lc reaching the blowing fan 320 is transferred to the blowing fan 320 and Liquid particles Lcp of the collecting liquid Lc formed while colliding are also actively contacted with the air A reaching the blowing fan 320. In this contact process, dust and other contaminants contained in the air (A) are collected in the collection liquid (Lc), and the natural vaporization of the water contained in the collection liquid (Lc) is induced, so that the air (A) is secondarily purified. And humidified.

On the other hand, the air A secondaryly purified by the blowing fan 320 is blown by the blowing fan 320 toward the water surface of the collecting liquid Lc filled in the inner space 312. In addition, the collected liquid Lc supplied to the blowing fan 320 is scattered toward the inner circumferential surface of the inner space 312 by centrifugal force, or by the air A blown by the blowing fan 320, the collected liquid Lc By moving toward the water surface of, the inner space 312 is recharged.

In addition, the air (A) blown toward the water surface of the collection liquid (Lc) is in contact with the water surface of the collection liquid (Lc), and is contained in the collection liquid (Lc) by the air (A) on the water surface of the collection liquid (Lc). Active natural vaporization of water is induced. For this reason, the collection liquid Lc may be discharged to the outside through the discharge port 316 in a state that is additionally humidified by water vapor generated by such natural vaporization.
