Through this, an installation space for installing the blower 20, the collection net 40, and the collection unit 50, which will be described later, can be secured between the supply port 13 and the discharge port 15, and the internal space 11 It is possible to prevent the collection liquid (Lc) stored in) from being directly discharged to the outside through the discharge port 15. It is preferable that a plurality of supply ports 13 are formed at predetermined intervals, but are not limited thereto.

This outlet 15 communicates the outside and the inside space 11 so that the air A accommodated in the inside space 11 can be guided to the outside. Then, as shown in FIG. 2, between the supply port 13 and the discharge port 15, a flow flow of air A from the supply port 13 toward the discharge port 15 is formed, and the inner space 11 Air (A) accommodated in may be discharged to the outside through the outlet (15).

Next, the blower 20 is a device that provides a driving force necessary for the air (A) accommodated in the inner space 11 to be discharged to the outside.

The structure of the blower 20 is not particularly limited, and at least one of various devices capable of blowing air A may be used as the blower 20. For example, as shown in FIG. 2, the blower 20 may be configured as an axial fan capable of sucking air A and blowing it in the axial direction. For convenience of explanation, the present invention will be described below based on a case where the blower 20 is configured as an axial fan.

The blower 20 is located at a height between the supply port 13 and the discharge port 15, but may be installed in the inner space 11 so as to face the water surface of the collecting liquid Lc. Preferably, the blower 20 may be installed so that the rotation shaft 22 and the inner space 11 of the blower 20 are concentric. The rotation shaft 22 is axially coupled to the internal space 11 or the driving motor 60 installed outside, and the blower 20 may be rotationally driven by the driving motor 60. It is preferable that the drive motor 60 rotates the blower 20 at a speed of 1500 RPM to 2000 RPM, but is not limited thereto.

The blower 20 may suck the air A accommodated in the inner space 11 and blow it toward the water surface of the collecting liquid Lc. Then, as shown in FIG. 2, the air blown by the blower 20 passes through the collection net 40, the collection unit 50, and the water surface of the collection liquid Lc in sequence, and then the discharge port ( 15) can be discharged to the outside.

Next, the collecting liquid supply unit 30 is a device for supplying the collecting liquid Lc to the collecting net 40 and the collecting unit 50.

The configuration of the collecting liquid supply unit 30 is not particularly limited. For example, the collecting liquid supply unit 30, as shown in FIG. 2, a collecting liquid pump 31 that pumps the collecting liquid Lc stored in the internal space 11, and the collecting liquid pump 31 The first collecting liquid supply pipe 32 for supplying the collecting liquid Lc pumped by the collecting network 40 and the collecting liquid Lc pumped by the collecting liquid pump 31 are described later. ) May be provided with a second collecting liquid supply pipe 33 and the like supplied to the tray 51.

The collecting liquid pump 31 is installed so that at least a part of the collecting liquid Lc is immersed in the collecting liquid Lc stored in the inner space 11 so as to be able to pump the collecting liquid Lc. The type of pump that can be used as the collecting liquid pump 31 is not particularly limited, and the collecting liquid pump 31 may be configured as a general pump used to pump a liquid substance. As shown in FIG. 2, one end of the connection pipe 34 may be mounted on the collecting liquid pump 31. The connection pipe 34 is a member for transferring the collecting liquid Lc discharged from the collecting liquid pump 31 to the first collecting liquid supply pipe 32 and the second collecting liquid supply pipe 33. The other end of the connection pipe 34 may be connected to the first port 35a of the three-way valve 35. The three-way valve 35 is a valve for selectively transferring the collection liquid Lc delivered from the connection pipe 34 to at least one of the first and second collection liquid supply pipes 32 and 33 by branching. Accordingly, the collected liquid Lc pumped by the collecting liquid pump 31 is introduced into the first port 35a of the three-way valve 35 through the connection pipe 34, and thus the second of the three-way valve 35 And it may be selectively delivered to the first collecting liquid supply pipe 32 and the second collecting liquid supply pipe 33 according to whether the third ports (35b, 35c) are opened or closed.

The collecting liquid pump 31 is preferably driven when the blower 20 and the floating member 55 of the collecting unit 50 to be described later are driven, but is not limited thereto.

The first collection liquid supply pipe 32 is provided to be able to supply the collection liquid Lc delivered from the connection pipe 34 to a predetermined position of the collection network 40. To this end, one end of the first collecting liquid supply pipe 32 may be connected to the second port 35b of the three-way valve 35, and the other end of the first collecting liquid supply pipe 32 is It extends to a position where the collection liquid Lc can be discharged toward a predetermined position. The predetermined position of the collection network 40 is not particularly limited. For example, as shown in FIG. 2, the other end of the first collection liquid supply pipe 32 discharges the collection liquid Lc delivered to the first collection liquid supply pipe 32 toward the center of the collection network 40 It is extended to the possible position. In addition, a spray nozzle 36 capable of spraying the collecting liquid Lc toward the center of the collecting net 40 may be installed at the other end of the first collecting liquid supply pipe 32.

When the first and second ports 35a and 35b of the three-way valve 35 are opened while the first and second ports 35a and 35b of the three-way valve 35 are opened, as the first collecting liquid supply pipe 32 is provided, the collecting liquid The collection liquid Lc pumped from the pump 31 may be sprayed to the center of the collection net 40 by the spray nozzle 36.

The second collecting liquid supply pipe 33 is provided to be able to supply the collecting liquid Lc transferred from the connection pipe 34 to the tray 51. To this end, one end of the second collecting liquid supply pipe 33 may be connected to the third port 35c of the three-way valve 35, and the other end of the second collecting liquid supply pipe 33 is connected to the inside of the tray 51 It may be connected to the tray 51 so as to communicate.

As the second collection liquid supply pipe 33 is provided as described above, when the collection liquid pump 31 is driven and the first and third ports 35a and 35c of the three-way valve 35 are opened, the collection liquid The collection liquid Lc pumped from the pump 31 may be filled in the tray 51 by the second collection liquid supply pipe 33. On the other hand, when the collecting liquid pump 31 is driven in the reverse direction, after the collecting liquid Lc filled in the tray 51 is discharged from the tray 51 by the negative pressure provided from the collecting liquid pump 31, It may be re-stored in the inner space 11 via the second collecting liquid supply pipe 33 and the collecting liquid pump 31.

3 is a partial cross-sectional view showing a state in which the collecting net is installed independently from the blower, FIG. 4 is a plan view of the collecting net shown in FIG. 1, and FIG. 5 is a partial enlarged view of the collecting net shown in FIG. 4, and FIG. 6 Is a diagram showing an aspect in which air is purified by a collecting net and a blower shown in FIG. 1.

Next, the collecting net 40 is a device for purifying the air A accommodated in the inner space 11 using a mesh structure.

The collecting net 40 is provided so as to be capable of purifying the air A accommodated in the inner space 11 while rotating about a central axis.

The installation position of the collecting net 40 is not particularly limited. For example, as shown in FIG. 1, the collecting net 40 is concentric with the rotation shaft 22 of the blower 20 and the central axis of the inner space 11, the blower 20 and the supply port ( 13) can be installed in between. Then, the air A sucked into the blower 20 may first pass through the collecting net 40 and then be transferred to the blower 20. However, the present invention is not limited thereto, and a collecting net 40 is installed between the blower 20 and the collecting unit 50 instead of between the supply port 13 and the blower 20, or the blower 20 and the collecting unit 50 ) In addition to the collecting net 40, other collecting nets may be additionally installed. In the case where the collecting net 40 is installed between the blower 20 and the collecting unit 50, the air blown from the blower 20 passes through the collecting net 40 first and then to the collecting unit 50. Can be delivered.

For convenience of explanation, the present invention will be described below based on a case where the collecting net 40 is installed between the blower 20 and the supply port 13.

The method of rotationally driving the collection net 40 is not particularly limited.

For example, as shown in FIG. 1, the central axis of the collecting net 40 may be axially coupled with the rotational shaft 22 of the blower 20. Then, as shown in FIG. 2, when the driving motor 60 is driven, the collecting net 40 may be driven to rotate along the blower 20. That is, the blower 20 and the collecting net 40 are rotated at the same time by the driving motor 60.

For example, as shown in FIG. 3, the central axis of the collection net 40 may be axially coupled to the inner space 11 or the externally installed driving motor 70 separately from the above-described driving motor 60. Then, the collection net 40 may be independently driven to rotate by the driving motor 70. It is preferable that the driving motor 70 rotates the collecting net 40 at a speed of 1500 RPM to 2000 RPM, but is not limited thereto. Accordingly, the controller 80 can drive the drive motors 60 and 70 at the same time or at two times, thereby rotating the blower 20 and the collecting net 40 at the same time or at two times.

For convenience of explanation, the present invention will be described below based on a case where the central axis of the collecting net 40 is axially coupled with the rotational shaft 22 of the blower 20.

The number of installations of the collection net 40 is not particularly limited. For example, the collection net 40 may be installed between the supply port 13 and the blower 20 with a plurality of collection nets 40 at predetermined intervals. In this case, by axially coupling the collecting nets 40 with the rotational shaft 22 of the blower 20, respectively, the collecting nets 40 and the blower 20 can be simultaneously rotated and driven.

For convenience of explanation, the present invention will be described below based on a case where one collecting net 40 is installed between the supply port 13 and the blower 20.

The shape of the collecting net 40 is not particularly limited. For example, as shown in FIG. 4, the collecting net 40 may have a disk shape. In this case, the collecting net 40 preferably has the same diameter as the blower 20 or smaller by a predetermined ratio than the blower 20, but is not limited thereto. That is, the collecting net 40 may have a larger diameter than the blower 20. In addition, when the collecting net 40 is axially coupled with the rotation shaft 22 of the blower 20, the insertion hole 42 into which the rotation shaft 22 of the blower 20 is inserted and fixed at the center of the collecting net 40 ) Can be formed.

As shown in FIG. 5, the collecting net 40 may have a net structure in which a plurality of nets 44 are formed. These areolaes 44 have a size and shape through which air (A) can pass.

The collecting net 40 is preferably formed of a material having good wettability with respect to the collecting liquid Lc. In addition, the collection net 40 may be formed of a flexible material that can be changed in shape. For example, as shown in FIG. 5, the collecting net 40 may be a woven fabric formed by woven warp 46 and weft 48 made of fibers. In this case, the collecting net 40 may be disposed in a state of being drooped by gravity when it is not rotated, and may be disposed in a state unfolded in a disc shape by centrifugal force when it is driven to rotate. However, the present invention is not limited thereto, and the collecting net 40 may be formed to maintain a constant shape by resisting gravity even when it is not rotated. For example, the collecting net 40 may be formed to be integrated by processing a high-rigidity synthetic resin, metal, or other material using a processing method such as injection or casting.

Hereinafter, a method of purifying the air A using the collecting net 40 and the blower 20 will be described with reference to the drawings.

As shown in FIG. 2, while driving the drive motor 60 and the collecting liquid pump 31, the first and second ports 35a and 35b of the three-way valve 35 are opened. Then, while the blower 20 and the collecting net 40 are driven to rotate, the collecting liquid Lc sprayed from the spray nozzle 36 is supplied to the center of the collecting net 40.

As shown in FIG. 6, the collecting liquid Lc supplied to the collecting net 40 is spread from the center of the collecting net 40 toward the outer periphery by the centrifugal force acting when the collecting net 40 rotates. It is distributed over the entire area of the collection network 40. Then, the collecting net 40 is rotated in a wet state by the collecting liquid Lc as a whole. By the way, as described above, the collecting net 40 is rapidly rotated along the blower 20 at a speed of 1500 RPM to 2000 RPM. For this reason, the collecting liquid Lc rotating along the collecting net 40 in a wet state of the collecting net 40 actively interacts with the air A reaching the collecting net 40 by the suction force of the blower 20. Contacted. In addition, as shown in FIG. 5, the collecting liquid Lc is formed by scattering from the collecting net 40 by the centrifugal force acting on the collecting net 40, or the collecting liquid Lc reaching the collecting net 40 ) The particles (Lcp) of the collecting liquid (Lc) formed while colliding with the mesh structure (for example, the warp 46, the weft 48) of the collecting net 40 are also air that has reached the collecting net 40. It is in active contact with (A). 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 primarily purified. Here, the particles (Lcp) of the collecting liquid (Lc) refer to the liquid particles of the collecting liquid (Lc) having a droplet shape.

As described above, the air (A) that is primarily purified by the collecting net 40 passes through the nets 44 and moves toward the blower 20. In addition, the collecting liquid Lc supplied to the collecting net 40 is scattered toward the inner circumferential surface of the inner space 11 by centrifugal force and stored again in the inner space 11, or by the suction force of the blower 20, the blower ( It is guided toward 20).

As shown in FIG. 6, the collected liquid Lc reaching the blower 20 is spread out from the center of the blower 20 toward the outer periphery by the centrifugal force acting when the blower 20 rotates. ) Is distributed over the entire area. Then, the blower 20 is rotated in a wet state with the collecting liquid Lc as a whole. Accordingly, the collecting liquid Lc that rapidly rotates along the blower 20 while wet the blower 20 is in active contact with the air A that has reached the blower 20. In addition, the collection liquid Lc is formed by scattering from the blower 20 by the centrifugal force acting on the blower 20, or the collection liquid Lc that has reached the blower 20 collides with the blower 20. The particles Lcp of the liquid Lc are also actively contacted with the air A that has reached the blower 20. In this contact process, first, other contaminants contained in the air A are collected in the collecting liquid Lc, so that the air A is secondarily purified.

In this way, the air A secondaryly purified by the blower 20 is blown by the blower 20 toward the water surface of the collecting liquid Lc stored in the inner space 11. In addition, the collected liquid Lc supplied to the blower 20 is scattered toward the inner circumferential surface of the internal space 11 by centrifugal force and rejoined into the collected liquid Lc stored in the internal space 11, or the blower 20 It is guided toward the water surface of the collected liquid Lc stored in the inner space 11 by the air blown by the air (A).

As above, the collecting liquid Lc supplied to the collecting net 40 and the blower 20 by the collecting liquid supply unit 30 is a centrifugal force acting upon rotation of the collecting net 40 and the blower 20 and the blower. It is separated from the collecting net 40 and the blower 20 by the flow of the air A formed by (20). That is, the collecting liquid Lc supplied to the collecting net 40 and the blower 20 is removed after wetting the collecting net 40 and the blower 20 for a while. Accordingly, the collecting liquid supply unit 30 continuously supplies the new collecting liquid Lc to the collecting network 40 and the blower 20 in accordance with the separation trend of the collecting liquid Lc. Then, the collecting net 40 and the blower 20 are cleaned by the new collecting liquid Lc continuously supplied by the collecting liquid supply unit 30. Through this, it is possible to prevent the growth of bacteria due to accumulation of the collecting liquid Lc in the collecting net 40 and the blower 20.

On the other hand, in general, the liquid has a characteristic that natural vaporization is promoted as the difference in the relative velocity with the gas in contact with it increases. By the way, the collecting liquid Lc rotates rapidly along the blower 20 or the collecting net 40 and comes into contact with the air A passing through the blower 20 or the collecting net 40. For this reason, in each of the collecting net 40 and the blower 20, natural vaporization of water contained in the collecting liquid Lc occurs actively. The water vapor generated by this natural vaporization is mixed with the air (A), and the air (A) can be humidified by the mixed water vapor. Accordingly, the air cleaning device 1 can be utilized as an air washer having both an air purification function and an air humidification function.

FIG. 7 is a partially enlarged view of the blower and collection unit shown in FIG. 1, and FIG. 8 is a partially enlarged view showing a state of use of the blower and collection unit shown in FIG. 2.

Next, the collecting unit 50 is a device for additionally purifying the air A purified by the collecting net 40 using the collecting balls 53.

As shown in FIG. 7, the collection unit 50 includes a tray 51 installed in the inner space 11, collection balls 53 loaded on the tray 51, and the inner space 11. A floating member 55 or the like for floating the collecting balls 53 from the tray 51 may be provided so that the accommodated air A and the collecting balls 53 are brought into contact with each other.

The tray 51 has a plate shape with an open upper side, and has a predetermined volume and height to accommodate a plurality of collection balls 53. The tray 51 is installed in the inner space 11 so as to be positioned on the flow of air A formed between the supply port 13 and the discharge port 15. For example, as shown in FIGS. 1 and 7, the tray 51 has a collection liquid ( It may be installed between the water surface of Lc) and the blower 20. Then, the air A blown from the blower 20 may flow toward the water surface of the collecting liquid Lc via the tray 51.

It is preferable that the sidewall of the tray 51 has an inclined structure in which the cross-sectional area of the tray 51 is gradually widened toward the blower 20. Through this, as illustrated in FIG. 8, it is possible to prevent the collection balls 53 which are freely fallen after being floated from the tray 51 by the floating member 55 from being separated from the tray 51.

The area of the tray 51 is not particularly limited. That is, as shown in Figure 8, the air (A) in contact with the collection balls 53 floating from the tray 51 by the floating member 55 is the inner peripheral surface of the tray 51 and the inner space 11 The tray 51 has a predetermined area so as to pass through the gap therebetween.

The number of trays 51 is not particularly limited, and at least one tray 51 may be installed in the inner space 11. When a plurality of trays 51 are installed, the trays 51 are installed at predetermined intervals. Then, the air A in contact with the collection balls 53 may pass through the gap between the trays 51. For convenience of explanation, the present invention will be described below based on a case where one tray 51 is installed in the inner space 11.

The tray 51 may be connected to the second collecting liquid supply pipe 33 of the collecting liquid supply unit 30. For example, as shown in FIG. 8, a communication hole 51a for communicating the inside of the tray 51 and the second collecting liquid supply pipe 33 may be formed on the sidewall of the tray 51. Accordingly, the collecting liquid Lc supplied from the second collecting liquid supply pipe 33 may be filled in the tray 51 by a predetermined level.

The collection balls 53 are accommodated in the tray 51 through the upper opening of the tray 51. As described above, when the collecting liquid Lc is filled into the inside of the tray 51, at least some of the collecting balls 53 accommodated in the tray 51 are filled in the inside of the tray 51. It may be infiltrated into the collection liquid (Lc).

The shape of the collecting balls 53 is not particularly limited. For example, as shown in FIG. 8, the collection balls 53 may have a spherical shape.

The diameter and number of the collecting balls 53 are not particularly limited. That is, the collection balls 53 are the distance between the tray 51 and the blower 20, the pressing force that the air blown by the blower 20 presses the collection balls 53 toward the tray 51 , It may have a predetermined diameter and number in response to environmental conditions such as a floating force applied to the collection balls 53 by the floating member 55, a volume of the tray 51, and the like.

It is preferable that the collecting balls 53 are formed of a material having good wettability for the collecting liquid Lc. For example, the collection balls 53 may be formed of quartz or other glass materials.

The floating member 55 is provided so that the collecting balls 53 accommodated in the tray 51 can float toward the space between the tray 51 and the blower 20. The structure of the floating member 55 is not particularly limited. For example, the floating member 55 is provided so that the collection balls 53 can be floated from the tray 51 by applying vibration to the tray 51. In this case, as shown in FIG. 8, the floating member 55 is a speaker for oscillating a sound wave S toward the tray 51 so that vibration is applied to the tray 51 via the sound wave S ( 57) and a sound wave guide 59 for guiding the sound wave S oscillated from the speaker 57 to the tray 51, and the like.

The type of speaker usable as the speaker 57 is not particularly limited, and the speaker 57 may be configured as a general speaker that oscillates by converting an electric signal into sound waves (S).

The speaker 57 is installed so as to oscillate sound waves S toward the tray 51. For example, as shown in FIG. 8, the speaker 57 is installed facing the lower surface of the tray 51 so as to oscillate sound waves S toward the lower surface of the tray 51.

The number of speakers 57 is not particularly limited, and at least one of the speakers 57 is installed so as to oscillate sound waves S toward the lower surface of the tray 51. When a plurality of speakers 57 are installed, the speakers 57 may oscillate sound waves S having the same waveform or may oscillate sound waves S having different waveforms. Hereinafter, the present invention will be described on the basis of a case in which one speaker 57 is installed.

According to the speaker 57, the sound wave S oscillated from the speaker 57 reaches the lower surface of the tray 51, and vibration may be applied to the tray 51 through the sound wave S. Then, as shown in FIG. 8, the collection balls 53 may be floated from the tray 51 by the vibration of the tray 51. That is, the sound wave S acts as a levitation force for floating the collecting balls 53 from the tray 51.

In this way, when the collecting balls 53 floated from the tray 51 by the speaker 57 rise toward the blower 20 and reach a predetermined height, they are freely dropped by gravity and are received in the tray 51 again. . That is, the collection balls 53 are accommodated in the tray 51 while flowing through the space between the tray 51 and the blower 20 by the energy transmitted from the speaker 57. However, when the collection balls 53 rise to the height at which the blower 20 is disposed, the collection balls 53 and the blower 20 may be damaged due to collision between the collection balls 53 and the blower 20. There is. On the other hand, if the collection balls 53 rise only at an excessively small height, it is difficult to sufficiently secure a contact time between the air blown by the blower 20 and the collection balls 53. To solve this, the speaker 57 is lower than the arrangement height of the blower 20 by a predetermined first reference interval or more, but is collected up to a height higher than the arrangement height of the tray 51 by a predetermined second reference interval or more. The sound wave S may be oscillated within a predetermined reference output range so that the balls 53 rise.

The sound wave guide 59 is formed extending from the outer circumferential surface of the speaker 57 and is mounted at a predetermined position of the tray 51. For example, as shown in FIG. 8, the sound wave guide 59 may be mounted on the lower surface of the tray 51. The sound wave guide 59 preferably has a conical shape in which a cross-sectional area gradually widens from the speaker 57 toward the tray 51, but is not limited thereto.

The interface between the acoustic guide 59 and the tray 51 may be sealed by an O-ring or other sealing member. Through this, leakage of the sound wave S through the interface between the sound wave guide 59 and the tray 51 may be prevented.

This sound wave guide 59, by intensively guiding the sound wave (S) oscillated from the speaker 57 to the tray 51, to minimize the energy of the sound wave (S) lost without reaching the speaker 57. I can.

Hereinafter, a method of purifying the air A using the collection unit 50 will be described with reference to the drawings.

The purification of the air A using the collection unit 50 is preferably carried out simultaneously with the purification of the air A using the collection net 40 and the blower 20. To this end, as shown in FIG. 2, while driving the drive motor 60, the collecting liquid pump 31, and the floating member 55, the first to third ports 35a of the three-way valve 35 , 35b, 35c) are all open. Then, as described above, in the collection net 40 and the blower 20, the air A is purified by the collection liquid Lc supplied from the spray nozzle 36, and the collection balls accommodated in the tray 51 53 rises and falls repeatedly according to the waveform of the sound wave S oscillated from the speaker 57.

As shown in FIG. 8, in the process of moving the space between the tray 51 and the blower 20 while the collection balls 53 repeatedly rise and fall, the collection balls 53 are It is brought into contact with the blown air (A). However, at least some of the collection balls 53 are accommodated in the tray 51 so as to be immersed in the collection liquid Lc filled in the tray 51, so that the collection balls 53 are repeatedly performed by the speaker 57. In the process of ascending and falling, the surfaces of the collecting balls 53 are wetted by the collecting liquid Lc. In addition, some of the collecting liquid Lc supplied to the blower 20 is guided toward the tray 51 by the air A (mainly in the form of particles Lcp), collecting balls 53 The surface of the fan is also wetted by the collecting liquid Lc delivered from the blower 20. Then, when the collecting balls 53 repeatedly rise and fall while flowing through the space between the tray 51 and the blower 20, the collecting liquid Lc wet the surfaces of the collecting balls 53 is the blower 20 It is actively in contact with the air (A) blown by

The vibration applied to the tray 51 may scatter the collecting liquid Lc filled in the tray 51 in the form of particles Lcp. In addition, as the collection balls 53 collide with each other in the process of repeatedly rising and falling of the collection balls 53, the collection liquid Lc is scattered from the surface of the collection balls 53 in the form of particles Lcp. Can be. When the scattered particles Lc of the collecting liquid Lc rise toward the blower 20 and reach a predetermined height, they fall freely by gravity and join the collecting liquid Lc filled in the tray 51. do. Accordingly, in the process of flowing the space between the tray 51 and the blower 20 while the particles Lcp of the collecting liquid Lc rise and fall, the particles Lcp of the collecting liquid Lc are blown by the blower 20 It is actively in contact with the air blown by (A).

As above, the collecting liquid Lc wetted the surface of the collecting balls 53 and the particles Lcp of the collecting liquid Lc formed in the process of rising and falling of the collecting balls 53 are in the blower 20 It is actively in contact with the air blown by (A). In such a contact process, dust and other contaminants contained in the air (A) are collected in the collection liquid (Lc), and the water contained in the collection liquid (Lc) is naturally evaporated, so that the air (A) is thirdly purified and Humidified.

As shown in Figure 2, the air (A) that is thirdly purified and humidified in the space between the tray 51 and the blower 20, the gap between the tray 51 and the inner circumferential surface of the inner space (11). After passing, it flows toward the water surface of the collection liquid Lc. Thereafter, the air (A) is in contact with the water surface of the collecting liquid (Lc), thereby inducing the natural vaporization of the water contained in the collecting liquid (Lc). Accordingly, the air A may be discharged to the outside through the outlet 15 in a state that is additionally humidified by water vapor generated by natural vaporization on the surface of the collecting liquid Lc.

On the other hand, when the purifying and humidifying work of the air (A) is completed, the first and third ports 35a and 35c of the three-way valve 35 are opened while the driving of the floating member 55 is stopped. At the same time, it is preferable to close the second port 35b and drive the collecting liquid pump 31 in the reverse direction. Then, in a state in which the supply of the collecting liquid Lc through the spray nozzle 36 is stopped, the collecting liquid Lc filled in the tray 51 is transferred from the tray 51 through the second collecting liquid supply pipe 33. It can be discharged and stored again in the internal space 11. In addition, when discharging the collecting liquid Lc from the tray 51 as described above, it is preferable to rotate the blower 20 for a predetermined time using the drive motor 60. Then, the air (A) blown by the blower 20 reaches the tray 51, and the collection liquid Lc that remains inside the tray 51 or wets the surface of the collection balls 53 is naturally vaporized. Can induce. By drying the tray 51 and the collection balls 53 through the collection and ventilation of the collection liquid Lc, the collection liquid Lc accumulates in the tray 51 and the collection balls 53, so that bacteria It can prevent it from proliferating.

For example, as shown in Figure 8, the lighting 19 is the inner space 11 so that light can be irradiated toward the collecting balls 53 flowing in the space between the tray 51 and the blower 20. It can be installed in a predetermined position. For example, as shown in FIG. 8, the lighting 19 may be fixedly installed on the inner circumferential surface of the inner space 11 so as to irradiate light toward the space between the tray 51 and the blower 20.

The number of installations of the lights 19 is not particularly limited, and at least one of the lights 19 may be installed at predetermined intervals.
