Referring to FIG. 1, the air cleaning device 100 according to a preferred embodiment of the present invention includes a predetermined flow path for the housing 110 and the air A contained in the inner space 112 of the housing 110. Blowing fan 120 that blows to flow along, and the air (A) flowing in the inner space 112 by the blowing fan 120 is installed to pass through, and the collection network 130 is rotationally driven around the central axis and , 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 illustrated in FIG. 1, the housing 110 includes air in the interior space 112 in which the collecting liquid Lc is filled by a predetermined water level, and outside of the housing 110 (hereinafter referred to as “outside”). A supply pipe 114 for guiding (A) to the interior space 112 and a discharge pipe 116 for guiding the air A of the interior space 112 to the outside may be provided. The exterior of the housing 110 means an indoor space in which the air cleaning device 100 is installed. In addition, the outside air (A) means the indoor air in the indoor space in which the air cleaning device 100 is installed.

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

The interior space 112 is used to form the swirling airflow S1 and the vortex V1, which will be described later, and to install various components provided in the air cleaning device 100, such as the blowing fan 120 and the collecting network 130. It is formed inside the housing 110 to have the required size of the volume. The collection liquid Lc may be filled in the internal space 112 by a predetermined water level.

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

The housing 110 is preferably provided to be able to exchange or recharge such collection liquid (Lc). For example, as shown in Figure 1, the housing 110, the upper surface is opened and the lower housing (110a) is filled with a predetermined level of the capture liquid (Lc), the lower surface is opened and the hook coupling, other coupling 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 between the lower housing 110a and the upper housing 110b to prevent the collection liquid Lc, air A, etc. from flowing out. .

The supply pipe 114 communicates with the inner space 112 so that the outside air A can be guided to the inner space 112. Therefore, when the air (A) accommodated in the inner space 112 is discharged to the outside by the blower fan 120 to be described later, when the negative pressure acts on the supply pipe 114, the external air (A) through the supply pipe 114 It may be supplied to the interior 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 the air A introduced from the outside through the inlet 114a is discharged, having a lower height than the water surface of the capture liquid Lc. In may be coupled to the circumferential surface of the housing 110 to communicate with the inner space (112). Then, the outside air (A) may be supplied into the water of the capture liquid (Lc) through the supply pipe (114). Through this, by increasing the contact area and the contact time of the air (A) and the capture liquid (Lc) supplied through the supply pipe 114, it is possible to improve the air purification efficiency of the air cleaning device (100).

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 interior space 112. Then, as shown in FIG. 3, in the inner space 112, the swirling air current S1 in which 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 ) Is formed.

In addition, as shown in FIG. 3, the collecting liquid Lc filled in the inner space 112 is rotated by the rotational force transmitted from the swirling air current S1 to form a vortex V1. In this way, the collecting liquid (Lc) that forms the vortex (V1) is formed in a cross-sectional shape of a 'U' shape in which the water level increases toward the inner circumferential surface of the inner space 112 by centrifugal force. Then, on the inner circumferential surface side of the inner space 112, while the air A on the swirling air stream S1 and the capture liquid Lc on the vortex V1 are sufficiently mixed with each other, the air A on the swirling air stream S1 and The contact between the collecting liquid Lc on the vortex V1 is actively made. Through this, dust and other contaminants included in the air A may be directly contacted with the collecting liquid Lc without being wrapped by air bubbles. Therefore, the collecting liquid Lc rotating along the inner circumferential surface of the inner space 112 actively 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 internal space 112 to guide the air A accommodated in the internal 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, and the opposite direction of gravity from the outlet 114b of the supply pipe 114. In addition to being spaced by a predetermined distance in the direction, the outlet 116b through which the air A introduced into the inlet 116a is discharged extends to the outside through the bottom surface of the inner space 112, It may be coupled to the lower portion, that is, the lower housing 110a.

When the discharge pipe 116 is provided as described above, as shown in FIG. 3, the air A accommodated in the interior 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, compared to the outlet 114b of the supply pipe 114, and is formed in the inner space 112 by the supply pipe 114 The turning airflow S1 has an aspect of the turning upward airflow. Then, as shown in FIG. 3, the air A accommodated in the inner space 112 rises toward the top of the inner space 112 by the swirling air flow S1. The housing 110 preferably has a cone shape in which the diameter gradually decreases toward the upper end so that the turning airflow S1 can be strengthened, but is not limited thereto.

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

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

The blowing fan 120 is preferably configured as an axial flow fan in an 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 (A) accommodated in the interior space 112 to flow along a predetermined flow path. For example, the blowing fan 120 may be installed to blow air (A) accommodated in the interior space 112 toward the inlet 116 of the discharge pipe 116. To this end, as shown in FIG. 3, the blower fan 120 is spaced a predetermined distance from the inlet 116a of the discharge pipe 116 in a direction opposite to the direction of gravity, but concentric with the discharge pipe 116 It can be installed at 112. That is, the blower fan 120 may be installed in the inner space 112 such that the rotation shaft 122 of the blower fan 120 and the central axis of the discharge pipe 116 are located in a straight line. The blower fan 120 sucks the air (A) in the interior space 112, more specifically, the air (A) rising to the top of the interior space 112 by the swirling air flow (S1) to discharge pipe 116 The air (A) blown by the blowing fan 120 may be discharged to the outside through the discharge pipe 116. Then, when the air accommodated in the inner space 112 is discharged to the outside using the blower fan 120, 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. ) May be re-supplied to the interior space 112.

By the way, the air (A) supplied to the interior space 112 through the supply pipe 114 forms a turning air stream (S1), but some of the air (A) can flow away from the turning air stream (S1) have. Due to this, some of the air (A) deviated from the swirling air flow (S1) flows along the outer circumferential surface of the discharge pipe 116, and then flows out through the discharge pipe 116 with dust and other contaminants intact. When discharged, there is a concern that the air purification efficiency of the air cleaning device 100 may decrease.

To solve this, the blowing fan 120 is provided so that some of the air (A) blown by the blowing fan 120 flows into the discharge pipe 116 and the other part flows along the outer circumferential surface of the discharge pipe 116 Can be. As shown in FIG. 3, in the case where the housing 110 is provided to form the swirling airflow S1 rising along the inner circumferential surface of the inner space 112, some of the air A deviated from the swirling airflow S1 The air (Ad) may rise along the outer circumferential surface of the discharge pipe (116). In this case, the blowing fan 120 is a part (Ae) of the air (A) blown by the blowing fan 120 is discharged to the outside through the discharge pipe 116 and the other portion (Ac) is discharge pipe 116 ) May be provided to descend along the outer peripheral surface. Then, the air (Ac) blown to flow (fall) along the outer circumferential surface of the discharge pipe 116 by the blower fan 120 (hereinafter, referred to as 'departure prevention air (Ac)') and the outer circumferential surface of the discharge pipe 116 Accordingly, the air Ad (which is hereinafter referred to as the "route out air Ad") deviating from the swirling air flow S1 to flow (rise) will proceed in opposite directions. Accordingly, the departure-avoiding air Ac may push out the path escape air Ad to prevent it from flowing further toward the inlet 116a of the discharge pipe 116. The path escape air Ad pushed by the escape prevention air Ac and the escape prevention air Ac passes through the space between the discharge pipe 116 and the inner circumferential surface of the inner space 112 and joins the swirling air flow S1. Therefore, the departure-avoiding air Ac may function as an air curtain that blocks the passage-out air Ad from directly flowing into the discharge pipe 116 without being purified. Through this, the blower 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 collecting liquid Lc. .

The method of installing the blower fan 120 to form the above-described air curtain is not particularly limited. For example, as illustrated in FIG. 3, the blower fan 120 may have a larger diameter than a discharge pipe 116 by a predetermined ratio. Then, the air A blown from the central region facing the discharge pipe 116 among the entire regions of the blowing fan 120 may be mainly discharged to the outside through the discharge pipe 116, and does not face the discharge pipe 116 The air A blown from the outer region 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 blower fan 120 is not particularly limited. For example, as illustrated in FIG. 3, the blower fan 120 may be rotationally driven by the drive motor 150 in which the rotation shaft 122 is axially coupled to the drive motor 150. The driving motor 120 is preferably installed in the interior space 112, but is not limited thereto. That is, the driving motor 120 may be installed outside the housing 110. The driving motor 150 is preferably driven to rotate the blowing fan 120 at a speed of 1500 RPM to 2000 RPM, but is not limited thereto.

On the other hand, if a blower fan, a pump, and other blowers (not shown) are additionally installed in a discharge pipe 116 or a duct connected to the discharge pipe 116, the blower fan 120 has air (A) in the interior space 112. It can be driven to rotate automatically by the airflow formed while being discharged to the outside by the blower. Therefore, in this case, the driving motor 150 may be omitted. In addition, an auxiliary blower (not shown) may be installed in the supply pipe 114 to assist the blowing fan 120 to supply external air A to the interior space 112.

4 is a plan view of the collection network shown in FIG. 1, FIG. 5 is a partially enlarged view of the collection network shown in FIG. to be.

Next, the collection network 130 is a device that induces the contact of the air (A) and the collection liquid (Lc).

As illustrated in FIG. 3, the central axis of the collecting network 130 may be axially coupled to the rotating shaft 122 of the blowing fan 120. Then, the collecting network 130 may be rotated together with the blowing fan 120, and concentrically formed with the blowing fan 120 and the discharge pipe 116. The collecting network 130 may be axially coupled with other driving motors (not shown) other than the above-described driving motor 150, instead of being axially coupled to the rotating shaft 122 of the blower fan 120, and independently rotated. . Hereinafter, for convenience of description, the central axis of the collecting network 130 is axially coupled to the rotating shaft 122 of the blowing fan 120, based on the case where the blowing fan 120 and the collecting network 130 are rotationally driven together. The present invention will be described as follows.

The installation location of the collecting network 130 is not particularly limited. For example, as illustrated in FIG. 3, the collecting network 130 collects liquid particles Lcp of the collecting liquid Lc formed by scattering the collecting liquid Lc on the vortex V1 by centrifugal force. To reach at least a portion of the network 130, it can be installed in a predetermined position. Then, the collecting network 130 can be supplied with the collecting liquid Lc as well as the collecting liquid supply unit 140 to be described later, as well as the turning 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 collecting network 130 is not particularly limited. For example, as illustrated in FIG. 3, the collecting network 130 is at least one axially coupled to the rotational shaft 122 of the blowing fan 120 so as to be located farther from the discharge pipe 116 compared to the blowing fan 120. The first collection network 131 of the, and at least one second collection network 133 that is axially coupled to the rotating shaft 122 of the blowing fan 120 to be located closer to the discharge pipe 116 than the blowing fan 120, etc. It may be provided. In this case, the first collecting network 131 is disposed between the upper end of the inner space 112 and the blowing fan 120, and the second collecting network 133 is between the blowing fan 112 and the outlet 116. Is placed on.

In addition, when the plurality of first collection networks 131 and the second collection networks 133 are installed, the first collection networks 131 and the second collection networks 133 are axes of the rotating shaft 122. It is installed at predetermined intervals in the direction, and may be individually coupled to the rotating shaft 122 individually.

Referring to FIG. 3, when the first collection network 131 and the second collection network 133 are installed as described above, the air A sucked by the blowing fan 120 is the first collection network 131, the blowing The fan 120 and the second collecting network 133 are sequentially passed.

The shape of the collecting network 130 is not particularly limited. For example, as illustrated in FIG. 4, the collecting network 130 may have a disc shape. In addition, the collecting network 130 is preferably the same diameter as the blowing fan 120 or a smaller diameter than the blowing fan 120, but is not limited thereto. That is, the collecting network 130 may have a larger diameter than the blowing fan 120. In addition, an insertion hole 132 in which the rotation shaft 122 can be inserted and fixed may be formed at the center of the collection network 130. Then, by inserting and fixing the rotating shaft 122 in the insertion hole 132, the collection network 130 can be coupled to the rotating shaft 122.

As shown in FIG. 5, the collecting network 130 may have a mesh structure in which a plurality of mesh eyes 135 are formed. The meshes 135 have a size and shape through which air A can pass.

The collection network 130 is preferably formed of a material having good wettability. In addition, the collecting network 130 may be formed of a flexible material that may have a variable shape. For example, as shown in FIG. 5, the collection net 130 may be a woven fabric formed by weaving 137 and weft 139 made of fibers. In this case, the collecting net 130 is disposed in a sagging state when gravity is not rotated, and can be rotated in a unfolded state by a centrifugal force when rotating. However, the present invention is not limited thereto, and the collecting network 130 may be formed to resist gravity even when not rotated and maintain the shape constant. For example, the collection network 130 may be formed to form a high-strength synthetic resin, metal, or other material by processing using a processing method such as injection or casting to form an integral body.

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

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

The collecting liquid pump 142 is installed so that at least a portion is immersed in the collecting liquid Lc filled in the inner space 112 so that the collecting liquid Lc can be pumped. The type of pump that can be used as the collection liquid pump 142 is not particularly limited, and the collection 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 network 130 is rotationally driven, but is not limited thereto.

The collection liquid supply pipe 144 is connected to the discharge port of the collection liquid pump 142 and extends the collection liquid Lc transferred from the collection liquid pump 142 to a position where it can be discharged toward a predetermined location of the collection network 130. do. For example, as illustrated in FIG. 3, when the first and

second collecting networks

131 and 133 are installed, the collecting liquid supply pipe 144 is air A sucked by the blowing fan 120. It may be installed to discharge the collection liquid (Lc) toward the center of the first collection network 131 to reach first. In addition, an injection nozzle 146 for spraying the collection liquid Lc toward the center of the first collection network 131 may be mounted at an end of the collection liquid supply pipe 144.

Hereinafter, with reference to the drawings, it will be described the aspect of the air (A) is purified in the collecting network 130.

First, the driving motor 150 and the collecting liquid pump 142 are driven. Then, the blowing fan 120 and the collecting network 130 are rotationally driven together, and in the injection nozzle 146, the collecting liquid Lc is injected toward the center of the first collecting network 131. Thus, as illustrated in FIG. 3, the swirling air current S1 and the vortex V1 are formed in the inner space 112, and the air A rising along the swirling air current S1 is caused by the vortex V1. The rotating collection liquid (Lc) and the inner circumferential surface of the inner space 112 are actively contacted. In this contacting process, the air A is primarily purified by collecting dust and other contaminants contained in the air A into the collecting liquid Lc rotated by the vortex V1.

In the 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 network 130. Then, the 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 network 130, and in particular, the central portion of the first collecting network 131 The collecting liquid (Lc) injected from the injection nozzle 146 is additionally supplied.

First, as shown in Figure 6, the swirling air flow (S1) and the collection liquid (Lc) supplied from the injection nozzle 146 to the first collection network 131, acts upon rotation of the first collection network 131 It is distributed over the entire area of the first collection network 131 while spreading from the center of the first collection network 131 toward the outside by a centrifugal force. Then, the first collection network 131 is rotated in a wet state by the collection liquid Lc as a whole. By the way, the first collection network 131 is rapidly rotated along the blowing fan 120 at a speed of 1500 RPM to 2000 RPM. Due to this, the collecting liquid Lc rotating along the first collecting network 131 in a state wetted with the first collecting network 131 reaches the first collecting network 131 by the suction force of the blowing fan 120. It is in active contact with the air (A). In addition, as illustrated 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 is applied to the first collection network 131. The liquid particles (Lcp) of the trapping liquid (Lc) formed while the reached trapping liquid (Lc) collides with the mesh structure of the first trapping network (131), and the air (A) reaching the first trapping network (131) Active contact. In this contacting process, air (A) is secondarily purified by collecting dust and other contaminants contained in the air (A) in the collecting liquid (Lc).

On the other hand, the air (A) secondaryly purified in the first collecting network 131 passes through the mesh eyes 135 of the first collecting network 131 and moves toward the blowing fan 120. In addition, some of the collection liquid (Lc) supplied to the first collection network 131 is scattered toward the inner circumferential surface of the inner space 112 by centrifugal force and then dropped by gravity to be recharged to the inner space 112, The remaining part of the collecting liquid (Lc) supplied to the first collecting network 131 is moved toward the blowing fan 120 by the suction force of the blowing fan 120.

Next, as shown in Figure 6, the swirling air flow (S1) and the collection liquid (Lc) supplied to the blowing fan 120 from the first collecting network 131, acts upon rotation of the blowing fan 120 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 centrifugal force. Then, the blowing fan 120 is rotated in a wet state by the collection liquid (Lc) as a whole. Accordingly, the collection liquid Lc rapidly rotating along the blowing fan 120 in a state in which the blowing fan 120 is wetted is actively contacted with the air A reaching 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 and the blowing fan 120 The liquid particles Lcp of the collecting liquid Lc formed while colliding are also actively in contact with the air A reaching the blowing fan 120. In the course of this contact, dust and other contaminants contained in the air A are collected in the collecting liquid Lc, thereby purifying the air A third.

On the other hand, the air (A) thirdly purified by the blowing fan 120 is blown toward the discharge pipe 116 by the blowing fan 120. In addition, some of the collection liquid (Lc) supplied to the blower fan 120 is scattered toward the inner circumferential surface of the inner space 112 by centrifugal force and then dropped by gravity to recharge the inner space 112, The remaining part of the collection 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 Figure 6, the swirling air flow (S1) and the collection liquid (Lc) supplied to the second collection network 133 from the blowing fan 120, when the second collection network 133 is rotated It is distributed over the entire area of the second collection network 133 while spreading from the center of the second collection network 133 toward the outside by the centrifugal force acting. However, the second collecting network 133 is rapidly rotated along the blowing fan 120 at a speed of 1500 RPM to 2000 RPM. For this reason, the collecting liquid Lc rotating along the second collecting network 133 in a state in which the second collecting network 133 is wetted is air blown into the second collecting network 133 by the blowing fan 120. It is in active contact with (A). In addition, as illustrated in FIG. 5, the collection liquid Lc is formed by scattering from the second collection network 133 by the centrifugal force acting on the second collection network 133, or the second collection network 133 is formed. The liquid particles (Lcp) of the collecting liquid (Lc) formed when the reaching the collecting liquid (Lc) collides with the mesh structure of the second collecting network (133), and the air (A) blown to the second collecting network (133) Contact. In the course of this contact, dust and other contaminants contained in the air A are collected in the collecting liquid Lc, thereby purifying the air A fourthly.

On the other hand, the air (A) that is fourthly purified in the second collection network 133 passes through the mesh eyes 135 of the second collection network 133 and is blown toward the discharge pipe 116, so that the air A is discharged through the discharge pipe 116. It is discharged to the outside. However, most of the collection liquid (Lc) supplied to the first collection network 131 and the blowing fan 120 is the inner circumferential surface of the inner space 112 in the first collecting network 131 and the blowing fan 120 by centrifugal force As it is scattered toward the side and recharged in the inner space 112, only a small amount of residual capture liquid Lc that is not recovered using the centrifugal force from the first collection network 131 and the blowing fan 120 is included in the second collection network 133. Is delivered. Due to this, in the second collecting network 133, the collecting liquid Lc is scattered toward the inner circumferential surface of the inner space 112 by centrifugal force, and the collecting liquid recovery action is recharged to the inner space 112, and the collecting liquid ( The air purification action by Lc) occurs relatively small. Accordingly, according to the second collection network 133, the first collection network 131 and the remaining collection liquid Lc that cannot be recovered from the blowing fan 120 can be recovered, and the second collection network 133 collects the collection liquid. (Lc) may function as a blocking network or a filter for blocking discharge to the outside through the discharge pipe 116 in a liquid state. Through this, the air cleaning device 100, even if used for a long time, the amount of the collection liquid (Lc) is kept constant within a predetermined reference range can hold the exchange period of the collection liquid (Lc) long, and the collection liquid ( As Lc) is discharged to the outside in a liquid state, bacterial contamination and other hygiene problems can be prevented.

Conventional solid filter type air cleaning devices are difficult to remove harmful substances, such as ultra-fine dust, mold, pollen, etc., which have a remarkably small particle size due to the characteristics of the HEPA filter. On the other hand, the air cleaning device 100 has a variety of contaminants, including ultra-fine dust with significantly small particle size, harmful substances such as mold and pollen, and water-soluble harmful gases such as sulfur dioxide (S02) and ammonia gas (NH3). By using the capture liquid (Lc) composed of water-based trapping as a liquid filter to purify the air (A), it is possible to improve air purification efficiency compared to a conventional air cleaning device. In addition, the collection liquid (Lc) is configured on the basis of water, it can have a large purification capacity and low price compared to the HEPA filter. Accordingly, the air cleaning device 100 may increase the convenience of maintenance by increasing the filter replacement cycle for a long time, and reduce the cost of maintenance by lowering the filter replacement cost.

In general, the liquid has a characteristic that the faster the flow rate of the gas in contact with it, the contact with the gas increases, or the lower the atmospheric pressure, the more natural vaporization is promoted. By the way, in the case of the air cleaning device 100, the collecting liquid (Lc) is not only in contact with the swirling air flow (S1) rapidly accelerated by the blowing fan 120, but also the blowing fan 120 or the collecting network 130 In accordance with the rapid rotation while in contact with the air (A) passing through the blowing fan 120 or the collection network 130 at high speed. For this reason, in the internal 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 the water is mixed with the air (A), and the air (Ae) can be discharged to the outside through the outlet 116 in a humidified state by the mixed water vapor. Accordingly, the air cleaning device 100 may be used as an air washer equipped with an air purifying function and an air humidifying function.

On the other hand, the collecting liquid (Lc) supplied to the blowing fan 120 and the collecting network 130, the blowing fan 120 and the collecting network by centrifugal force acting upon rotation of the blowing fan 120 and the collecting network 130 It is separated from 130 and recharged into the interior space 112. That is, the collecting liquid Lc is not accumulated in the blowing fan 120 and the collecting network 130 for a long time, but is collected again after only soaking the blowing fan 120 and the collecting network 130 for a while. Due to this, the blower fan 120 and the collecting network 130 can be repeatedly washed with a new collecting liquid Lc continuously supplied by the turning airflow S1 or the collecting liquid supply unit Lc. Through this, the air cleaning device 100 can prevent the bacteria from growing due to the accumulation of the collecting liquid Lc in the blowing fan 120 and the collecting network 130 for a long time.

Referring to FIG. 7, the outlet 116 of the air cleaning device 100 may be connected by an air curtain device 600 and an air supply line 610 installed at entrances and exits of various facilities. Then, air (Ae) discharged from the air cleaning device 100 is supplied to the air curtain device 600, thereby purifying the air curtain that blocks outside air from the outdoor space from entering the indoor space in the air cleaning device 100 It can be formed by using clean air (Ae). Through this, it is possible to improve the quality of the bet in the indoor space of the facility where the air curtain device 600 is installed.

In addition to the purpose of grafting the air cleaning device 100 with the air curtain device 600, the air cleaning device 100 may be used for various purposes. That is, the air cleaning device 100 constitutes various products such as an air purifier, an outdoor air supply, a humidifier, and an air cleaner that can be used in various fields such as residential facilities, commercial facilities, industrial facilities, road facilities, transportation means, and electronic products. Can be used to

The air cleaning device 200 according to the second embodiment of the present invention, in that the structure of the housing 210 and the installation positions of the blowing fan 220 and the collecting network 230 are changed, the above-described air cleaning device It has a difference from the device 100. Hereinafter, the air cleaning device 200 will be described based on the difference, and descriptions of the air cleaning device 100 that are overlapped with the above will be omitted or only briefly described.

As shown in FIG. 8, the supply pipe 214 is a surface of the collecting liquid Lc in which the outlet 214b through which the air A introduced from the outside is discharged through the inlet 214a is filled in the inner space 212. It can be coupled to the circumferential surface of the housing 210 so as to communicate with the interior space 212 at a high position. Then, the outside air (A) may be supplied to the space above the water surface of the collection liquid (Lc) through the supply pipe (214). In addition, the discharge pipe 216, the inlet 216a through which the air in the interior space A flows is lower than the outlet 214b of the supply pipe 214, and the collection liquid Lc filled in the interior space 212 It is located higher than the water surface, and 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. It can be coupled to the top.

In addition, the blowing fan 220 is installed to be able to blow the air (A) accommodated in the interior space 212 along a predetermined flow path. For example, the blowing fan 220 may be installed to be able to blow air (A) accommodated in the interior space 210 toward the inlet 216a of the outside air discharge pipe 216. To this end, the blower 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, but the inner space is concentric with the discharge pipe 216 It can be installed at 212. The rotating shaft 220 of the blower fan 220 may be coupled to the inner space 212 or the driving motor 250 installed outside. Accordingly, the blower fan 220 may be rotationally driven by the driving motor 250.

The collecting network 230 includes a first collecting network 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 216 ) May be provided with a second collection network 233 installed between the inlets 216a. It is preferable that the central axis of the first collection network 231 and the central axis of the second collection network 233 are axially coupled to the rotation axis 222 of the blowing fan 220, respectively. However, the present invention is not limited thereto, and the collection network 230 may be axially coupled to a driving motor (not shown) other than the above-described driving motor 250, and may be independently driven to rotate. For convenience of description, hereinafter, the central axis of the collecting network 230 is axially coupled to the rotating shaft 222 of the blowing fan 220 based on the case where the blowing fan 220 and the collecting network 230 are driven together. The present invention will be described.

As illustrated in FIG. 9, when the driving motor 250 and the collecting liquid pump 242 of the collecting liquid supply unit 240 are driven, the air received in the interior space 212 while the blowing fan 220 is rotationally driven ( A) is discharged to the outside through the discharge pipe 216, and the external air (A) is reconnected to the interior space 212 through the supply pipe 214 by the negative pressure applied to the interior space 212 and the supply pipe 214. Is supplied. The air A re-supplied to the inner space 212 forms a turning airflow S2 descending while turning the inner space 212 along the inner circumferential surface, and the inner space (S2) is generated by the turning airflow S2. A vortex V2 is formed in the collection liquid Lc filled in 212). Accordingly, the air (A) and the collecting liquid (Lc) orbiting along the inner circumferential surface of the inner space 212 are actively contacting each other, and dust and other contaminants contained in the air (A) are collected in the collecting liquid (Lc), The air (A) is primarily purified and humidified by inducing natural vaporization of water contained in the capture liquid (Lc).

In addition, the air A descending to the lower end of the inner space 212 along the swirling air flow S2 is blown from the center of the lower end of the inner space 212 by the suction force applied by the blowing fan 220 ( 220). Then, the air A raised toward the blowing fan 220 sequentially passes through the first collecting network 231, the blowing fan 220, and the second collecting network 233. The air (A) is supplied to the first collection network 231, the blowing fan 220, and the second collection network 233 by the rotating air stream S2 and the injection nozzle 246 of the collection liquid supply unit 240. After being further purified and humidified by the collected liquid (Lc), it is discharged to the outside through the discharge pipe (216).

Meanwhile, reference numeral '244', which is not described, denotes a collection liquid supply pipe that delivers the collection liquid Lc pumped by the collection liquid pump 240 to the injection nozzle 246.

In the air cleaning device 300 according to the third embodiment of the present invention, the structure of the housing 310 and the installation positions of the blowing fan 320 and the collecting network 330 have been changed. It has a difference from the devices (100, 200). Hereinafter, the air cleaning device 300 will be described based on these differences, and descriptions of the

air cleaning devices

100 and 200 that are duplicated will be omitted or only briefly described.

First, the housing 310 includes an inner space 312 in which the collecting liquid Lc is filled by a predetermined water level, a supply port 314 for guiding the outside air A to the inner space 312, and the inside. A discharge port 316 for guiding the air A of the space 312 to the outside may be provided. The housing 310 is preferably a hollow cylindrical cylinder 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 internal space 312. The number of installations of the supply port 314 is not particularly limited, and at least one supply port 314 may be openly formed in the housing 310.

The outlet 316 is formed to open the circumferential surface of the housing 310 so as to communicate with the interior space 312, and may be formed to be positioned at a lower height than the supply hole 314. The number of installations of the outlet 316 is not particularly limited, and at least one outlet 316 may be open in the housing 310.

Next, the blowing fan 320 is installed to be able to blow the air (A) accommodated in the interior space 312 along a predetermined flow path. For example, the blower fan 320 may be installed to allow air (A) accommodated in the inner space 312 to be blown toward the surface of the collection liquid (Lc) filled in the inner space 312. To this end, the blower fan 320 is installed in the interior space 312 to be positioned at a height between the supply hole 314 and the discharge hole 316, and may be installed to face the water surface of the collection 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 form concentricity. The rotating shaft 322 is axially coupled to the inner space 312 or the driving motor 350 installed externally, so that the blowing fan 320 may be rotationally driven by the driving motor 350. The blowing fan 320 may blow the air A accommodated in the inner space 312 toward the water surface of the collecting liquid Lc.

Next, the collecting network 330 is axially coupled to the rotating 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 collecting network 330 may be axially coupled to a drive motor (not shown) other than the above-described drive motor 350, and may be independently driven to rotate. For convenience of description, hereinafter, the present invention will be described based on the case where the central axis of the collecting network 330 is axially coupled to the rotating shaft 322 of the blowing fan 320.

The installation location of the collection network 330 is not particularly limited. For example, the collection network 330 may be installed in the interior space 312 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 network 330 is installed between the blowing fan 320 and the surface of the collecting liquid Lc, or the blowing fan 320 Another collection network may be additionally installed between the water surface of and the collection liquid Lc.

The collecting liquid supply unit 340 collects the collecting liquid pump 342 for pumping the collecting liquid Lc filled in the inner space 312 and the collecting liquid Lc pumped by the collecting liquid pump 342. A collection liquid supply pipe 344 for discharging toward a predetermined position of the network 330 may be provided. The predetermined position of the collecting 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, an injection nozzle 346 for spraying the collection liquid Lc toward the center of the collection network 330 may be mounted at an end of the collection liquid supply pipe 344.

Hereinafter, an aspect in which the air A is purified in the collecting network 330 will be described.

First, the driving motor 350 and the collecting liquid pump 342 are driven. Then, while the blowing fan 320 and the collecting network 330 are rotationally driven, the collecting liquid Lc is sprayed from the injection nozzle 346 toward the center of the collecting network 330.

The collection liquid (Lc) supplied from the injection nozzle 346 to the collection network 330 spreads from the center of the collection network 330 toward the outside by the centrifugal force acting upon rotation of the collection network 330 and the collection network 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 network 330 in a state in which the collecting network 330 is wetted includes air (A) reaching the collecting network 330 by the suction force of the blowing fan 320. Active contact. In addition, the collecting liquid (Lc) is formed by scattering from the collecting network 330 by the centrifugal force acting on the collecting network 330, or the collecting liquid (Lc) reaching the collecting network 330 of the collecting network 330 The liquid particles Lcp of the collecting liquid Lc formed while colliding with the mesh structure are also actively contacting the air A reaching the collecting network 330. In this contacting process, air (A) is primarily purified by inducing natural vaporization of water contained in the collecting liquid (Lc) while dust and other contaminants contained in the air (A) are collected in the collecting liquid (Lc). And humidified.

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

Next, the collection liquid (Lc) supplied from the collecting network 330 to the blowing fan 320 is spread from the center of the blowing fan 320 toward the outside by centrifugal force acting upon rotation of the blowing fan 320. As it goes, it is distributed over the entire area of the blower fan 320. Then, the blowing fan 320 is rotated in a wet state by the collection liquid (Lc) as a whole. Accordingly, the collecting liquid Lc rapidly rotating along the blowing fan 320 in a state in which the blowing fan 320 is wetted is actively contacted with the air A reaching 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 and the blowing fan 320 The liquid particles Lcp of the collecting liquid Lc formed while colliding are also actively in contact with the air A reaching the blowing fan 320. In this contacting process, air (A) is secondarily purified by inducing natural vaporization of water contained in the collecting liquid (Lc) while dust and other contaminants contained in the air (A) are collected in the collecting liquid (Lc). And humidified.

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

In addition, the air A blown toward the water surface of the collecting liquid Lc is brought into contact with the surface of the collecting liquid Lc, and the surface of the collecting liquid Lc is contained in the collecting liquid Lc by air A. Active natural vaporization of water is induced. Due to this, the collection liquid (Lc) can be discharged to the outside through the outlet 316 in a further humidified state by the water vapor generated by this natural vaporization.

Hereinafter, the air cleaning device 400 will be described based on these differences, and the description of the content that overlaps with the air cleaning device 300 will be omitted or only briefly described.

First, the housing 410, the supply port 414 for guiding the outside air (A) to the interior space 412, and the outlet 416 for guiding the air (A) in the interior space 412 to the outside, etc. It may be provided. The housing 410 preferably has a hollow cylindrical cylinder shape, but is not limited thereto.

The outlet 416 may be formed by opening the other side of the housing 410 opposite to the one side so as to communicate with the inner space 412. The number of installations of the outlet 416 is not particularly limited, and at least one outlet 416 may be openly formed in the housing 410.

Next, the blowing fan 420 is installed to be able to blow the air (A) accommodated in the interior space 412 along a predetermined flow path. For example, the blower fan 420 may be installed to blow air A accommodated in the inner space 412 toward the outlet 416. To this end, the blowing fan 420 is installed in the inner space 412 to be located between the supply hole 414 and the discharge hole 416, but may be installed to face the discharge hole 416. Preferably, the blowing fan 420 may be installed such that the rotating shaft 422 and the outlet 416 of the blowing fan 420 are concentric. The rotating shaft 422 is axially coupled to the inner space 412 or a driving motor 450 installed outside, and through this, the blowing fan 420 may be rotationally driven by the driving motor 450. The blowing fan 420 may blow air (A) accommodated in the inner space 412 toward the outlet 416.

Next, the collecting network 430 is axially coupled to the rotating shaft 422 of the blowing fan 420 so that it can be rotated along the blowing fan 420. The collecting network 430 may be axially coupled to a driving motor (not shown) other than the driving motor 450 described above, and may be independently driven to rotate.

The installation location of the collection network 430 is not particularly limited. For example, the collection network 430 may be installed in the inner space 412 to be located between the supply port 414 and the blowing fan 420. However, the present invention is not limited thereto, and instead of between the supply opening 414 and the blowing fan 420, a collecting network 430 is installed between the blowing fan 420 and the outlet 416, or the blowing fan 420 and the outlet ( 416) may be additionally installed another collection network.

The collection liquid supply unit 440, the collection liquid (Lc) is stored, the internal space 412 or the collection liquid storage chamber 442 installed in the outside, and the capture liquid (Lc) stored in the capture liquid storage chamber 442 ), A collection liquid pump 444 for pumping, and a collection liquid supply pipe 446 for supplying the collection liquid Lc pumped by the collection liquid pump 444 to a predetermined position of the collection network 430. Can be. The predetermined position of the collecting network 430 is not particularly limited. For example, the collection liquid supply pipe 446 may be provided to discharge the collection liquid Lc pumped by the collection liquid pump 444 toward the center of the collection network 430. In addition, an injection nozzle 448 for spraying the collection liquid Lc toward the center of the collection network 430 may be mounted at an end of the collection liquid supply pipe 446.

The air cleaning device 400 stores the collection liquid Lc in the collection liquid storage chamber 442 provided separately from the housing 410, and the air A blown by the blowing fan 420 It is the same as the air cleaning device 300 described above, except that it is discharged directly to the outside through the outlet 416 without additional contact with the water surface of the collecting liquid Lc. Accordingly, a description of a specific aspect in which the air A is purified by the air cleaning device 400 will be omitted.

The air cleaning apparatus 500 according to the fifth embodiment of the present invention, as shown in FIGS. 12 to 14, has a collecting network to purify the air A using only the swirling air flow S5 and the vortex V5. Except that it is omitted, the same as the vacant cleaning device 500 according to the first embodiment of the present invention described above, hereinafter, the air cleaning device 500 will be described based on these differences.

12 to 14, the air cleaning device 500 according to an embodiment of the present invention includes a housing 510, at least one supply pipe 520, an exhaust pipe 530, and a blower ( 540). Hereinafter, each component will be described in detail with reference to FIGS. 12 and 13.

The housing 510 is a component for forming a swirl airflow S5 with respect to the air A supplied from the outside. As illustrated in FIG. 12, such a housing 510 may have a hollow cylindrical cylinder shape and a closed structure, and the collection liquid Lc may be filled in the inner space 512 by a predetermined water level. .

In addition, the housing 510 may be made of a polycarbonate material having excellent impact resistance, so as to prevent shape deformation or damage due to the swirling air flow S5. The polycarbonate can provide a transparency close to glass due to the nature of the material, and through this, the degree of contamination of the collecting liquid Lc filled in the housing 510 and foreign matter generated or introduced into the inner space 512 of the housing 510 This can be observed from the outside.

Further, the housing 510 may have a detachable structure so that the collection liquid Lc filled in the inner space 512 can be exchanged.

The detachable portion C30 may have an engaged structure, and a sealing member (not shown) made of rubber or silicone may be further provided in the engaged portion.

The supply pipe 520 is a component for guiding the outside air A (ie, the air A outside the air cleaning device 500 of the present invention) to the inner space 512 of the housing 510 to be. 12, such a supply pipe 520 may be connected to the circumferential surface of the housing 510. In addition, as shown in Figure 13, the supply pipe 520, the circumferential surface of the housing 510 to form a more smooth turning air flow (S5) to the outside air (A) supplied through the supply pipe 520 It can be connected in a tangential direction. In addition, a plurality of supply pipes 520 may be connected at predetermined intervals to the circumferential surface of the housing 510.

In addition, as illustrated in FIG. 12, the outlet 521 of the supply pipe 520 may be located at a different height from the inlet 531 of the discharge pipe 530. For example, the outlet 521 of the supply pipe 520 may be positioned at a higher point than each of the water surface of the collection liquid Lc filled in the inner space 512 and the inlet 531 of the discharge pipe 530.

The discharge pipe 530 is a component for guiding the air A accommodated in the inner space 512 of the housing 510 to the outside. An upward airflow is formed in the inner center of the swirling airflow S5, and the air A moved through the upward airflow enters the inlet 531 of the exhaust pipe 530 and then exits 532 of the exhaust pipe 530 It can be discharged to the outside.

In addition, as shown in FIG. 12, the discharge pipe 530 may be provided to have a smaller diameter than the housing 510 but concentric with the housing 510 (ie, the same central axis C10). As such, by providing the housing 510 of the discharge pipe 530 to be concentric, it is possible to more smoothly form the swirling air stream S5.

In addition, as shown in FIG. 12, the inlet 531 of the discharge pipe 530 may be located at a different height from the outlet 521 of the supply pipe 520 described above.

For example, as illustrated in FIG. 12, the inlet 531 of the discharge pipe 530 is lower than the outlet 521 of the discharge pipe 520 but may be located at a higher point than the water surface of the collection liquid Lc. have. Then, as shown in FIG. 12, since the inlet 531 of the discharge pipe 530 is not immersed in the collecting liquid Lc, this prevents the collecting liquid Lc from being drained out through the inlet 531. Can be.

The blower 540 is a component for forcibly flowing air A. The installation position of the blower 540 is not particularly limited. For example, as shown in FIG. 12, the blower 560 may be installed in the discharge pipe 530. The type of the blower member usable as the blower 540 is not particularly limited. For example, an axial fan, pump, or the like can be used as the blower 540.

On the other hand, as shown in Figure 12, the air cleaning device 500 according to the fifth embodiment of the present invention, is installed in the supply pipe 520, the auxiliary blower forcing air (A) into the interior space 512 It may further include (550). The type of the blowing member usable as the auxiliary blower 550 is not particularly limited. For example, an axial fan, pump, or the like can be used as auxiliary blower 550.

According to the auxiliary blower 550, the flow force due to the inflow of air A by the auxiliary blower 550 may be additionally added to the flow force due to the outflow of air A by the blower 540. Bars, even if the capacity of the blower 540 is small, it is possible to form a swirling air flow S5 of sufficient strength to purify the air A. Through this, the blower 540 can be designed to have a small capacity, so even if the air cleaning device 500 is turned on at night, the generation of noise can be minimized, and the user can take a good night's sleep while maintaining a clean air. have.

Hereinafter, an aspect in which the air A is purified by the air cleaning device 500 will be described.

First, when the blower 540 and the auxiliary blower 550 are driven, the air A received in the inner space 512 of the housing 510 by the flow force provided by the blower 540 and the auxiliary blower 550 While being discharged to the outside through the discharge pipe 530, the outside air (A) is supplied to the inner space 512 through the supply pipe (520).

By the way, the cylindrical shape of the housing 510, the supply pipe 520 is connected to the circumferential surface of the housing 510 in the tangential direction of the housing 510, in the inner space 512 through the supply pipe 520 The swirling air current S5 in which the supplied air A rotates along the inner circumferential surface of the inner space 512 is formed. In addition, the inlet 531 of the discharge pipe 530 is located at a lower height than the outlet 521 of the supply pipe 520, and the air supplied to the interior space 512 through the outlet 521 of the supply pipe 520 (A) is drawn toward the inlet 531 of the discharge pipe 530, that is, in the downward direction. Due to this, the turning airflow S5 has the aspect of the turning downdraft. The swirling air flow S5 is formed to extend from the outlet 521 of the supply pipe 520 to the bottom surface of the inner space 512. In addition, on the bottom surface of the inner space 512, the upward airflow is formed to penetrate the inner center of the swirling airflow S5, so that the air A deviated from the swirling airflow S5 is discharged through the upward airflow 530 It can be discharged to the outside by flowing into the inlet 531 of.

On the other hand, the collecting liquid (Lc) filled in the inner space 512 is rotated along the inner circumferential surface of the inner space 512 by the rotational force transmitted from the swirling air flow (S5) to form a vortex (V5). As described above, the collection liquid Lc having the vortex V5 forms a cross-sectional shape of a 'U' shape in which the water level rises toward the inner circumferential surface of the inner space 512 by centrifugal force. Then, on the inner circumferential surface side of the inner space 512, while the air A on the swirling air flow S5 and the capture liquid Lc on the vortex V5 are sufficiently mixed with each other, the air A on the swirling airflow S5 and The contact between the collecting liquid Lc on the vortex V5 is actively made. Through this, dust and other contaminants included in the air A may be directly contacted with the collecting liquid Lc without being wrapped by air bubbles. Therefore, the collecting liquid Lc rotating along the inner circumferential surface of the inner space 512 effectively purifies the air A by actively collecting dust and other contaminants contained in the air A and removing it from the air A. can do. In addition, due to the active contact between the air (A) on the swirling air flow (S5) and the trapping liquid (Lc) on the vortex (V5), the active natural vaporization of water contained in the trapping liquid (Lc) is induced. Can be humidified by water vapor produced by this natural vaporization.

Therefore, as shown in FIG. 16, the air A supplied through the outlet 621 of the supply pipe 620 to the inner space 612 of the housing 610 is compared to the outlet 621 of the supply pipe 620. It is pulled toward the inlet 631 of the discharge pipe 630 in the high position, that is, in the upward direction. Due to this, the direction of the turning air flow (S6) is determined in the upward direction, the turning air flow (S6) is an aspect of the turning upward air flow extending from the outlet 621 of the supply pipe 620 to the ceiling surface of the inner space 612 Can have In addition, as shown in FIG. 15, the inlet 622 of the supply pipe 620 prevents the collection liquid Lc filled in the inner space 612 of the housing 610 from flowing out through the supply pipe 620. It may be positioned higher than the surface of the collection liquid (Lc) filled in the interior space (612).

In addition, the inlet 631 of the discharge pipe 630 may be located at a higher point than each of the water surface of the outlet 621 and the collection liquid (Lc) of the supply pipe 620, as shown in FIG.
