The outlet of the humidification passage 106 and the inlet of the discharge passage 107 are connected to each other. Therefore, the discharge humidifying medium 55 may be disposed in the discharge passage 107 .

Since the connection passage 103, the humidification passage 106, and the discharge passage 107 are not formed through a structure such as a duct, it is difficult to clearly distinguish the boundaries. However, when the humidification flow path 106 for humidification is defined between the water tank humidification medium 51 and the discharge humidification medium 55 , the connection flow path 103 and the discharge flow path 107 are naturally defined.

The connection flow path 103 is defined between the blower housing 150 and the water tank humidification medium 51 . The discharge passage 107 is defined after the discharge humidifying medium 55 . .

The filtered air is humidified by the water naturally evaporated from the humidifying medium 50 . The spontaneous evaporation refers to evaporation of water without additional heat applied. As the contact with air increases, the flow velocity of air increases, and the pressure in the air decreases, spontaneous evaporation is promoted. The spontaneous evaporation is also referred to as spontaneous evaporation.

The humidifying medium 50 promotes natural evaporation of water. In this embodiment, the humidifying medium 50 is wetted with water, but is not submerged in the water tank 300 .

Since the water stored in the water tank 300 is spaced apart and disposed separately, even if there is water stored in the water tank 300, the water tank humidification medium 51 and the discharge humidification medium 55 are not always wet. That is, the water tank humidification medium 51 and the discharge humidifying medium 55 are wet only when operating in the humidification mode, and when operating in the air cleaning mode, the water tank humidifying medium 51 and the discharge humidifying medium 55 are dry. can be kept as it is.

Referring to FIG. 8 , the watering housing 800 is configured to spray water stored in the water tank 300 . The watering housing 800 has a structure for efficiently pumping water stored in the water tank 300 .

The watering housing 800 is rotated by receiving the rotational force of the watering motor 42, and when rotating, the water stored in the water tank 300 is sucked inside and then pumped upward. The water pumped into the watering housing 800 is discharged through the injection hole 410 (refer to FIG. 14 ).

A pumping means is disposed in the watering housing 800 . The pumping means pumps the water in the water tank 300 upward. A method of pumping water in the tank may be implemented in various ways.

For example, after pumping water through the pump, it may be sprayed.

For example, the water may be pumped by rotating the watering housing and forming friction or mutual interference with water during rotation.

A plurality of positive grooves 802 may be disposed on the inner surface of the watering housing 800 . The plurality of positive grooves 802 may be disposed in plurality along the circumferential direction (circumferential direction) of the watering housing 800 .

The lower end of the watering housing 800 is spaced apart from the bottom surface of the water tank 300 by a predetermined distance to form suction intervals 801 and H1. The water in the water tank 300 is sucked into the watering housing 800 through the suction interval 801 .

The water level H2 of the water tank 300 to which the watering housing 800 can spray water is higher than the suction interval H1 and lower than the injection hole 410 . The water level H2 includes a full water level.

When the water level (H2) is lower than the suction interval (H1), since water is not sucked, pumping is impossible. When the water level H2 is higher than the injection hole 410 , the water pumped into the injection hole 410 is not sprayed.

The number of the injection holes 410 may be adjusted according to design conditions. In this embodiment, a plurality of the injection holes 410 are disposed in the watering housing 800 with a difference in height. The injection hole disposed on the upper side of the watering housing 800 is defined as a second injection hole, and the injection hole disposed in the middle of the watering housing is defined as the first injection hole.

Water sprayed from the first injection port is used for humidification. The water sprayed from the second injection port is used for humidification, watering, and rainview.

Water sprayed from the second injection port may flow down to wet the tank humidification medium.

After the water sprayed from the second injection port collides with the visual body, it may be scattered to form a rain view. After the water sprayed from the second injection port collides with the visual body, it is converted into fine droplets, and these droplets can be used for watering to wash the filtered air.

When the watering housing 800 is rotated at a first rotational speed or more, water may be injected from the first injection port. When the watering housing 800 is rotated at a second rotation speed or more, water may be injected from the second injection port.

The second rotation speed is higher than the first rotation speed.

Only when the watering housing 800 is rotated at a high speed, water is discharged from the second injection port. At a speed at which the watering housing 800 is normally rotated, it may be disposed so that water is not discharged through the second injection port. The first injection port discharges water at all stages in which the watering housing is routinely operated.

A plurality of the second injection holes may be disposed. A plurality of the first injection holes may be disposed.

When the watering housing 800 is rotated at a normal rotation speed, the pumped water rises higher than the minimum first injection port. When the watering housing 800 rotates at a high speed, the pumped water rises above the height of the second injection port.

A plurality of the second injection holes may be disposed in the circumferential direction of the watering housing 800 . A plurality of the first injection holes may also be disposed in the circumferential direction of the watering housing 800 .

If the watering housing 800 is not rotated, water is not discharged through the injection hole 410 . When the user operates only in the clean mode (the mode in which the air clean module is operated and the air wash module is stopped), the watering unit 40 is not operated, and only the blowing unit 20 is operated. When the user operates only in humidification mode, the watering housing 800 is rotated, and water is discharged through the injection hole 410 . When the user simultaneously operates the clean mode and the humidification mode, the water discharged from the injection hole 410 may be sprayed on the inner surface of the visual body 210 .

Since the watering housing 800 is rotated, the water discharged from the injection hole 410 hits the inner surface of the visual body 210 and moves along the inner surface of the visual body 210 .

The user can visually confirm that water is sprayed through the visual body 210 . This spray of water means that it is operating in a humidification mode. The user can intuitively check that the humidification mode is in operation by spraying water.

Droplets are formed on the visual body 210 by the sprayed water, and the droplets flow down.

Also, unlike the present embodiment, the watering housing 800 may receive rotational force other than the power transmission shaft. For example, the rotational force of the watering motor may be transmitted in a belt-pulley method. For example, the rotational force of the watering motor may be transmitted through a gear meshing method. For example, the rotational force of the watering motor may be transmitted in a chain manner. For example, the rotational force of the watering motor may be transmitted by a clutch method.

One of the first coupler 610 and the second coupler 620 is male, and the other is female. In this embodiment, the first coupler 610 is a male shape, and the second coupler 620 is manufactured in a female shape. In this embodiment, the first coupler 610 is detachably coupled to the second coupler 620 in the form of being inserted. Unlike this embodiment, the second coupler 620 may be coupled to the first coupler 610 to be inserted.

The watering motor 42 is installed on the upper body 120 . The watering motor 42 is positioned above the blower motor 22 and is spaced apart from the blower motor 22 . The water tank 300 is mounted inside the upper body 120 . When the water tank 300 is mounted on the upper body 120, the first and second couplers 610 and 620 are connected to transmit power. The watering motor shaft 43 of the watering motor 42 is disposed to face upward. A first coupler 610 is installed on the upper end of the watering motor shaft 43 .

Each configuration of the watering housing 800 will be described as follows.

The first watering housing 820 is formed by opening the upper and lower sides, respectively, and the positive groove 802 and/or the positive rib 810 is formed on the inner surface. The lower end of the first watering housing 820 is spaced apart from the bottom of the water tank 300 by a predetermined distance to form a suction gap 801 .

The second watering housing 840 is formed by opening the upper and lower sides, respectively, and is assembled on the upper end of the first watering housing 820 .

The watering housing cover 860 is coupled to the upper end of the second watering housing 840 and covers an upper surface of the second watering housing 840 .

The watering power transmission unit 880 is connected to at least one of the first watering housing 820 and the second watering housing 840 to receive the rotational force of the power transmission module 600 . In this embodiment, the watering power transmission unit 880 is connected to the first watering housing 820 .

Unlike the present embodiment, the first watering housing 820 and the second watering housing 840 may be integrally manufactured. Also, unlike this embodiment, the first watering housing 820 and the watering housing cover 860 may be integrally manufactured.

An upper cross-section of the first watering housing 820 is wider than a lower cross-section. The first watering housing 820 is inclined in the vertical direction. The first watering housing 820 may have a conical shape having a narrow lower cross-section.

A positive rib 810 is formed inside the first watering housing 820 . The positive groove 810 is formed in the vertical direction. The positive ribs 810 are radially disposed with respect to the watering motor shaft 43 . A plurality of the positive ribs 810 may be disposed and protrude toward the center of the axis of the watering housing 800 .

The lower end of the first watering housing 820 is spaced apart from the inner bottom of the water tank 300 to form a suction interval 801 . The upper end of the first watering housing 820 is coupled to the lower end of the second watering housing 840 .

The first watering housing 82 and the second watering housing 840 can be assembled and disassembled. In this embodiment, the first watering housing 820 and the second watering housing 840 are assembled through screw coupling. A screw thread 822 is formed on the upper outer circumferential surface of the first watering housing 820 , and a screw thread 842 is formed on the lower inner circumferential surface of the second watering housing 840 .

A thread 822 formed in the first watering housing 820 is defined as a first thread 822 , and a thread 842 formed in the second watering housing 840 is defined as a second thread 842 . do.

A first barrier 823 restricting movement of the second watering housing 840 is formed below the first screw thread 822 . The first barrier 823 is formed in the circumferential direction of the first watering housing 820 . The first barrier 823 is formed in a band shape and protrudes to the outside of the first watering housing 820 .

When the first watering housing 820 and the second watering housing 840 are assembled, the first barrier 823 is in close contact with the lower end of the second watering housing 840 . The first barrier 823 is formed to protrude further outward than the first screw thread 822 .

A first packing 825 is disposed between the first thread 822 and the first barrier 823 . The first packing 825 blocks water from leaking between the first watering housing 820 and the second watering housing 840 . The first packing 825 is formed of an elastic material. The first packing 825 is formed in a ring shape.

A packing installation rib 824 is disposed to fix the position of the first packing 825 . The packing installation rib 824 may be disposed on an extension line of the first screw thread 822 . The packing installation rib 824 may be a part of the first screw thread 822 .

So, the first screw thread 822 may be formed in plurality, and may be discontinuously distributed and disposed, and one of them may be the packing installation rib 824 .

A first injection hole 411 is disposed in the first watering housing 820 . In this embodiment, two of the first injection holes 411 are disposed. The two first injection holes 411 are formed to face each other in opposite directions.

The first injection hole 411 communicates the inner and outer sides of the first watering housing 820 . In this embodiment, the inner opening area of the first injection hole 411 is formed to be larger than the outer opening area. The first injection port 411 supplies water to the water tank humidifying medium 51 and wets the water tank humidifying medium 51 . The first injection port 411 may be injected toward the water tank humidification medium (51).

Watering wings 850 are formed on the outer peripheral surface of the second watering housing 840 . The watering wings 850 may flow humidified air. When the watering housing 800 rotates, the watering wings 850 may draw in surrounding air. The watering wings 850 have a function not only for flowing air, but also as a rainbow directing means for refining droplets.

Most of the air in the humidification passage 106 in which the watering housing 800 is disposed flows toward the discharge passage 107 by the flow of the blowing fan 24, but the air around the watering blade 850 is on the contrary. can be moved. The watering blade 850 may locally form an air flow opposite to the air flow by the blowing fan 24 . Depending on the shape of the watering blade 850, the air may flow in the same direction as the flow by the blowing fan 24. Even at this time, the air around the watering housing 800 may be collected on the surface of the watering housing 800 by the rotation of the watering blade 850 .

The air flow by the watering blade 850 has an effect of flowing water particles around the watering housing 800 into the water tank 300 . The rotation of the watering blade 850 has the effect of generating air volume and attracting water particles around the watering housing 800 .

So, the air flow by the watering blade 850 serves to collect the falling water toward the watering housing 800 when water falls from the water supply passage 109 to the upper portion of the watering housing 800 . do.

When the watering housing 800 is rotated, when water is supplied through the water supply passage 109 , the water may be irregularly scattered by hitting the surface of the watering housing 800 . The air flow by the watering blade 850 may collect water particles scattered during supply of water toward the surface of the watering housing 800 .

The second watering housing 840 has second injection holes 412 and 413 formed therein. The second injection ports 412 and 413 spray water toward the visual body 210 . In this embodiment, two of the second injection holes 412 and 413 are disposed. One of the second injection holes is referred to as a 2-1 injection hole 412 and the other one is defined as a 2-2 injection hole 413 .

The 2-1th injection hole 412 and the 2-2nd injection hole 413 are disposed to face different directions. In this embodiment, the 2-1th injection hole 412 and the 2-2nd injection hole 413 are disposed to face each other. The 2-1th injection hole 412 and the 2-2nd injection hole 413 may be symmetrically disposed with respect to the power transmission shaft 640 .

When viewed in a plan view, the 2-1th injection hole 412 and the 2-2nd injection hole 413 form an angle between them of 180 degrees. When viewed in a plan view, the 2-1 injection hole 412 is disposed between the watering blades 850 . The 2-2nd injection hole 413 is also disposed between the watering blades 850 .

When viewed from the front, the heights of the 2-1th injection hole 412 and the 2nd-2nd injection hole 413 are equal to or higher than the watering blade 850 . Some of the trajectories S3 and S4 of the water sprayed from the 2-1th injection hole 412 and the 2nd-2nd injection hole 413 are located within the rotation radius of the wandering wing 850 .

So, when the watering housing 800 is rotated, some of the water sprayed from the 2-1 th injection port 412 and the 2-2 th injection port 413 collides with the watering wing 850 and scatters.

In this embodiment, the 2-1th injection hole 412 and the 2-2nd injection hole 413 form a predetermined height difference. The 2-1th injection hole 412 and the 2-2nd injection hole 413 are not disposed at the same height.

By forming a height difference between the 2-1th injection hole 412 and the 2nd-2nd injection hole 413 , the position of the water colliding with the visual body 210 can be set differently. Therefore, when the watering housing 800 is rotated, the water dispersed from the 2-1th injection hole 412 and the water sprayed from the 2nd-2nd injection hole 413 pass through different paths.

A trajectory (S3, see FIG. 31) of water colliding with the inner surface of the visual body 210 at the second injection holes 412 and 413 is defined as an injection line.

Referring to FIG. 13 , the injection line formed by the 2-1th injection hole 412 is defined as a first injection line L1 , and the injection line formed by the 2-2nd injection hole 413 is formed by the second injection It is defined by line L2.

The injection line formed on the visual body 210 does not mean only a straight line. The injection line may form a curve according to an angle discharged from the injection port.

In addition, the thickness of the injection line may be formed differently depending on the diameter of the injection hole. That is, if the diameter of the injection hole is large, the injection line may be formed to be thick, and if the diameter is small, the injection line may be formed to be thin.

In this embodiment, after the water dispersed in the 2-1 injection hole 412 passes by based on any one of the visual body 210, it is sprayed from the 2-2 injection hole 413 at a different height after a predetermined time. water will pass through. That is, two injection lines (L1) and (L2) are formed on the inner surface of the visual body 210, and the user can more effectively recognize that water is being sprayed through this visual presentation.

When water is discharged from the two second injection ports disposed at a constant height, only one injection line is formed. When the watering housing 800 is rotated at a high speed, even if the first and second second injection holes 142 and 143 are positioned in opposite directions, the phase difference may be extremely short. In this case, an optical illusion may be caused by water flowing down from one spray line.

On the other hand, in the case of forming two injection lines, since the locations where the water collides are different, the sound generated by the collision is also formed differently. That is, the sound generated from the first injection line and the sound generated from the second injection line are formed differently. Through this sound difference, the user can audibly confirm that the watering housing 800 is being rotated.

When only one injection line is formed, since the same sound is continuously generated, the user may not recognize it or mistake it for simple noise.

The sound difference through the plurality of injection lines has the effect of effectively conveying the operation situation to the low-vision or hearing impaired. In addition, it can be easily confirmed that the humidification cleaning device is operating even in the absence of light.

Referring to FIG. 8 , at least one of the second injection holes 412 and 413 may be disposed to be partially covered by the watering housing cover 860 . In this embodiment, the 2-1th injection hole 412 is disposed in a completely open state, and the 2-2nd injection hole 413 is partially overlapped and covered by the watering housing cover 860 .

The watering housing cover 860 is positioned in front of the 2-2nd injection hole 413 . The watering housing cover 860 partially covers the upper side of the 2-2nd injection hole 413 .

In this embodiment, when the watering housing cover 860 is coupled to the second watering housing 840, it overlaps with a part of the 2-2nd injection hole 143. In this embodiment, the watering housing cover 860 is used as a diffusion member. Unlike the present embodiment, a separate diffusion member for widely spreading the water sprayed from the injection hole may be disposed.

For example, when the watering housing is injected, a burr may be intentionally formed, and the water sprayed through the burr may be diffused.

The water sprayed from the 2-2nd injection hole 413 may interfere with the diffusion member, so that the injection angle and width may be changed. The water interfering with the diffusion member is pulled toward the diffusion member by the surface tension.

In the 2-1 injection hole 412 in which the overlap with the diffusion member is not formed, the diameter of the injection hole and the diameter of the discharged water are similarly formed. Water is sprayed in a wider range than the diameter of the injection hole from the 2-2nd injection hole 413 overlapping the watering housing cover 860 .

The trajectory of the water sprayed from the 2-1th injection hole 412 is defined as S3 (refer to FIG. 31), and the trajectory of the water sprayed from the 2nd-2nd injection hole 413 is defined as S4 (refer to FIG. 32).

The 2-2nd injection hole 413 is positioned slightly higher than the 2-1 injection hole 412 . The 2-2nd injection hole 413 partially overlaps with the cover body border 863 of the watering housing cover 860, which is a diffusion member.

Since the water sprayed through the 2-2nd injection hole 413 is injected while interfering with the cover body border 863, the injected water is more finely sprayed.

The droplet ejected from the 2-2nd injection hole 413 is smaller than the droplet ejected from the 2-1th injection hole 412 . The trajectory S4 of the droplet ejected from the 2-2nd injection hole 413 is formed above the trajectory S3 injected from the 2-1 th injection hole 412 . The droplet sprayed from the 2-2nd injection hole 413 is sprayed wider than the droplet sprayed from the 2-1th injection hole 412 . Therefore, compared to the injection line L1 formed by the 2-1 injection hole 412, the width of the injection line L2 formed by the overlapping 2-2 injection hole 413 is formed to be wider.

On the other hand, the watering wings 850 can flow the air around the watering housing 800 as well as refine the water sprayed from the injection port 410 .

In the present embodiment, the water sprayed from the second injection holes 412 and 413 collides with the watering blade 850 and is refined. The watering wings 850 may refine the water in the form of mist.

The watering wings 850 do not refine all the water sprayed from the second injection holes 412 and 413 . Some of the water sprayed from the second injection holes 412 and 413 collides with the watering wing 850 .

The water sprayed from the two injection holes 412 and 413 forms a predetermined trajectory S3, and the rotating watering blade 850 collides with the water on the trajectory S3. That is, among the water sprayed from the second injection ports 412 and 413, some collide with the watering wing 850 and scatter, and the rest do not collide with the watering wing 850 and the inside of the body of the visual body 210 hit the side

The water colliding with the watering blade 850 is widely scattered in the humidification passage 106, not in a specific direction. For example, water scattered from the watering blade 850 may wet the discharge humidifying medium 55 . Water scattered from the watering wings 850 may be formed on the visual body 210 . Water scattered from the watering blade 850 may be suspended on the humidification passage 106 .

The water refined by the watering wings 850 is effective in directing a rain view. The miniaturized droplets are formed in the form of small droplets on the inner surface of the visual body 210 .

Instead of the watering wings 850 , a rain view directing means may be disposed between the watering housing 800 and the visual body 210 . Water sprayed from the injection hole 410 may collide with the rainbow directing means and scatter. For example, a mesh may be disposed as a rainbow directing means between the visual body 210 and the watering housing 800 . The water sprayed from the wintering housing 800 may be dispersed after being crushed into smaller droplets while passing through the mesh.

Meanwhile, the rain view generated in the humidification flow path 106 may generate negative ions due to the Lenard effect.

The Leonard effect is a phenomenon in which a large amount of negative ions are generated when water is pulverized by a large external force.

Droplets scatter and collide in the process of creating a rain view, and a large amount of negative ions are generated in this process.

When the water sprayed from the first injection hole 411 collides with the structure, negative ions may be generated by the Leonard effect.

In addition, when the water sprayed from the second injection holes 412 and 413 collides with the visual body 210, negative ions may be generated by the Leonard effect.

In addition, when the water sprayed from the second injection holes 412 and 413 collides with the watering wings 850, negative ions may be generated by the Leonard effect.

In addition, during upper water supply, when the droplets scattered from the watering housing cover 860 collide with various structures, negative ions may be generated by the Leonard effect.

As such, in the present embodiment, droplets of various sizes for producing a rain view have an effect of generating negative ions during the generation process. The generated negative ions are discharged into the room through the discharge passage 107 .

Meanwhile, referring to FIGS. 12 and 14 , a water film restraining rib 870 for suppressing a water film rotational flow is formed inside the second watering housing 840 . The water film rotational flow refers to a rotational flow along the inner surface of the watering housing 800 .

The positive water rib 810 of the first watering housing 820 is for forming the water film rotational flow, and the water film restraining rib 870 is for suppressing the water film rotational flow.

Since the first watering housing 820 has to pump water to raise it up to the second watering housing 840 , the water film rotational flow is actively generated, but the water raised up to the second watering housing 840 is As the silver water film rotation flow is not formed, it is easier to spray through the second injection holes 412 and 413 .

When a high-speed water film rotational flow is formed inside the second watering housing 840, water flows along the inside without being discharged through the second injection port.

In addition, as a large amount of water stays in the second watering housing 840, the vibration of the watering housing 800 increases. The water pumped up to the second watering housing 840 must be rapidly sprayed through the second injection ports 412 and 413 to minimize the eccentricity of the watering housing 800, and thus also to minimize vibration. .

The water film suppression rib 870 serves to minimize the water film rotational flow, thereby minimizing the eccentricity and vibration of the watering housing 800 .

The water film suppression rib 870 is formed to protrude from the inner surface of the second watering housing 840 . In this embodiment, the water film restraining rib 870 is formed to protrude toward the power transmission shaft 640 . The water film restraining rib 870 is formed in a direction crossing the water film rotation flow.

The water film rotational flow is spirally or circularly flowed along the inner surface of the second watering housing 840, and the water film restraining rib 870 is preferably formed in the vertical direction.

In this embodiment, the water film restraining ribs 870 are formed in a vertical direction. A plurality of water film restraining ribs 870 may be formed. In this embodiment, three water film restraining ribs 870 are disposed. The plurality of water film restraining ribs 870 are arranged at equal intervals with respect to the inner circumferential surface of the watering housing.

In this embodiment, the protrusion length of the water film restraining rib 870 is 5 mm. The protrusion length of the water film restraining rib 870 is related to the thickness of the water film rotation flow, and may be variously changed according to the embodiment.

In the present embodiment, the water film suppression rib 870 is formed in connection with the watering power transmission unit 880 . Unlike the present embodiment, the water film suppression rib 870 and the watering power transmission unit 880 may be separately disposed.

In this embodiment, the mold can be simplified by manufacturing the water film suppression rib 870 to be connected to the watering power transmission unit 880 .

15 to 17 , the watering power transmission unit 880 is configured to transmit the rotational force of the power transmission shaft 640 to the watering housing 800 .

In this embodiment, the watering power transmission unit 880 is connected to the second watering housing 840 . Unlike the present embodiment, the watering power transmission unit 880 may be connected to the first watering housing 820 .

In this embodiment, the watering power transmission unit 880 is manufactured integrally with the second watering housing 840 . Unlike the present embodiment, the watering power transmission unit 880 may be separately manufactured and then assembled to the second watering housing 840 .

The watering power transmission unit 880 includes a bushing installation part 882 positioned at the axial center of the watering housing 800 and a watering connection part connecting the bushing installation part 882 and the watering housing 800 . (884). In this embodiment, the bushing installation part 882, the watering connection part 884, and the second watering housing 820 are manufactured integrally by injection.

The watering connection part 884 is manufactured in the form of a rib. The water ring connection part 884 is radially disposed with respect to the axial center, and a plurality is formed.

In this embodiment, the water ring connection part 884 is manufactured integrally with the water film suppression rib 870 . The water ring connection part 884 and the water film suppression rib 870 are connected to each other.

The power transmission shaft 640 is installed to pass through the bushing installation part 882 .

The lower side of the bushing installation part 882 is opened. The bushing 90 is inserted through the opened lower side of the bushing installation part 882 .

The bushing installation part 882 and the bushing 90 may be separated in the vertical direction. The bushing installation part 882 and the bushing 90 form mutual engagement in the rotational direction.

To this end, a bushing engaging part 93 is formed in any one of the bushing installation part 882 or the bushing 90, and a bushing engaging groove 883 is formed in the other one. In this embodiment, the bushing locking part 93 is formed on the bushing 90 , and the bushing locking groove 883 is formed on the bushing installation part 882 .

The bushing locking groove 883 is formed on the inner surface of the bushing installation part 882, and has a concave shape. The bushing engaging portion 93 is formed on the outer surface of the bushing 90, and has a convex shape.

The bushing engaging portion 93 is inserted into the bushing engaging groove 882 is fitted.

Unlike this embodiment, the bushing installation part 882 and the bushing 90 may be integrally manufactured. Since the bushing 90 is formed of a metal material, when the second watering housing 840 is manufactured, the bushing 90 is disposed in the mold and then the second watering housing material is injected to be integrally manufactured.

The bushing 90 is coupled to the power transmission shaft 640 of the power transmission module 600 .

The bushing 90 is coupled to the power transmission shaft 640 to receive rotational force. The bushing 90 is preferably formed of a metal material. If it is not made of hard metal, abrasion may occur, which causes vibration.

The bushing 90 is formed with a hollow bushing shaft penetrating in the vertical direction. The power transmission shaft 640 is inserted into the bushing shaft hollow.

The bushing 90 reduces vibration when the watering housing 800 is rotated. The bushing 90 is positioned on the power transmission shaft 640 . In this embodiment, the bushing 90 is located at the center of gravity of the watering housing 800 . Since the center of gravity of the watering housing 800 is located in the bushing 90 , vibration of the watering housing 800 during rotation can be significantly reduced.

The bushing 90 and the power transmission shaft 640 are assembled by fitting. The bushing 90 is supported on the power transmission shaft 640 .

A shaft support end 642 is formed on the power transmission shaft 640 to support the bushing 90 . Based on the shaft support end 642, the upper diameter is small and the lower diameter is large.

The bushing 90 is inserted through the upper end of the power transmission shaft 640 .

The shaft support end 642 may be formed in a tapered, chamfered, or round shape to minimize wear. When the shaft support end 642 is formed at a right angle, wear may occur during the assembly process or the operation process.

When the shaft support end 642 is worn, the bushing 90 moves and causes vibration. In addition, when the shaft support end 642 is worn, the bushing 90 may be inclined or moved, which may cause misalignment with the power transmission shaft 640 . In addition, when misalignment of the bushing 90 and the power transmission shaft 640 occurs, eccentricity is generated during rotation, and vibration is generated thereby.

The watering housing cover 860 is coupled to the upper side of the second watering housing 840 and seals the upper side of the second watering housing 86 . The watering housing cover 860 is screwed to the second watering housing 840 .

In this embodiment, the watering housing cover 860 is assembled with the power transmission module 600 . Unlike the present embodiment, the watering housing cover 860 may be formed separately from the power transmission module 600 .

When the watering housing cover 860 is coupled to the power transmission shaft 640 , eccentricity and vibration of the watering housing 800 can be more effectively reduced.

14 and 15 , the watering housing cover 860 includes a cover body 862 that covers an upper opening of the second watering housing 840, and extends downward from the cover body 862. A cover body border 863 surrounding the upper end of the second watering housing 840, formed below the cover body 862, and spaced apart from the cover body border 863 by a predetermined distance. It includes a packing installation rib 864 , a shaft fixing part 866 fixed to the power transmission shaft 640 , and a reinforcing rib 868 connecting the shaft fixing part 866 and the packing installation rib 864 .

The cover body 862 is formed in a circular shape in a plan view. The diameter of the cover body 862 is larger than the diameter of the second watering housing 840 .

Unlike the present embodiment, the planar shape of the cover body 862 may not be circular. In addition, the planar shape of the watering housing 800 is also not limited to a specific shape.

The cover body border 863 forms an edge of the cover body 862 . The cover body border 863 is formed in a ring shape, and is manufactured integrally with the cover body 862 . A plurality of protrusions 861 are formed on the outer surface of the cover body border 863, and the protrusions 861 are formed at 360 degrees along the circumferential direction. The protrusion 861 provides a feeling of grip to the user when the watering housing cover 860 is removed.

In addition, the protrusion 861 can effectively scatter water falling during upper water supply. Water falling through the upper water supply falls to the watering housing cover 860 and flows to the cover body border 863 by rotation of the watering housing 800 . After separation in the form of water droplets from the projections 861, it is sprayed on the inner surface of the visual body 210. The protrusion 861 can effectively scatter the water supplied to the top.

The panking installation rib 864 is located inside the cover body border 863 and is spaced apart from the cover body border 863 by a predetermined distance. A second packing 865 is installed between the cover body border 863 and the packing installation rib 864 .

The second packing 865 may seal between the watering housing cover 860 and the second watering housing 840 . Since leakage of water in the housing space 805 is blocked through the first packing 825 and the second packing 865 , it is possible to maintain a constant pressure of water discharged through the injection hole 410 .

When water leaks between the first watering housing 820 and the second watering housing 840, or water leaks between the second watering housing 840 and the watering housing cover 860, It is difficult to maintain a constant pressure of water discharged from the injection port 410 .

That is, when water leakage occurs in the watering housing 800 , even if the watering housing 800 is rotated, water may not be sprayed from the injection hole 410 .

The cover body border 863 and the second watering housing 840 may be screwed together. In this embodiment, the watering housing cover 860 and the second watering housing 840 are press-fitted and assembled.

The shaft fixing part 866 is assembled with the power transmission shaft 640 and receives rotational force from the power transmission shaft 640 .

The shaft fixing part 866 and the power transmission shaft 640 may be screwed together. To this end, a screw thread 643 for screwing with the watering housing cover 860 is formed on the upper outer peripheral surface of the power transmission shaft 640 .

A screw thread for assembly with the power transmission shaft 640 may be formed in the shaft fixing part 866 . In this embodiment, the shaft fixing member 867 is disposed on the shaft fixing part 866 , and the shaft fixing member 867 is double-injected into the shaft fixing part 866 and integrated. In this embodiment, a nut is used for the shaft fixing member 867 .

Unlike the watering housing cover 860, the shaft fixing member 867 is made of a metal material. Since the power transmission shaft 640 is formed of a metal material, a portion screwed with the power transmission shaft 640 should also be formed of a metal material to prevent wear or damage during fastening. When the entire watering housing cover 860 is formed of a metal material, or when the shaft fixing part 866 is formed of a metal material, it is preferable to form a screw thread in the shaft fixing part 866 itself.

The watering housing cover 860 is formed to be larger than the diameter of the second watering housing 840 . When viewed from the top, only the watering housing cover 860 is exposed, and the second watering housing 840 and the first watering housing 820 are not exposed.

Therefore, at least a portion of the water supplied to the water supply passage 109 may fall to the watering housing cover 860 . When the watering housing 800 is rotated, the water that has fallen to the watering housing cover 860 is sprayed radially outward from the surface of the watering housing cover 860 .

The rotating watering housing cover 860 sprays the supplied water along the rotational direction, and can implement the same effect as water dripping from the umbrella. In particular, water droplets may be peeled off from the plurality of protrusions 861 disposed in the circumferential direction of the watering housing cover 860 .

The water sprayed from the watering housing cover 860 in the rotational direction may collide with the inner surface of the visual body 210 to produce a rain view.

The rain view refers to a situation in which droplets formed on the inner surface of the visual body 210 appear as if raindrops are flowing.

Referring to FIG. 12 , in this embodiment, the pumping rib 810 is designed in a form that can effectively pump water in the water tank 300 . In this embodiment, the positive rib 810 is positioned lower than the injection hole 410 . In particular, the positive rib 810 is formed lower than the first injection hole 411 .

The positive rib 810 converts a horizontal rotational force with respect to water in a vertical direction. When the pumping ribs 810 are formed, water can be pumped more effectively in the vertical direction.

In this embodiment, the positive ribs 810 are formed on the inner surface of the watering housing 800 and protrude inward. The positive ribs 810 are formed to extend long in the vertical direction. Unlike the present embodiment, the positive ribs 810 may be formed in a zigzag shape. In this embodiment, since the first watering housing 82 is manufactured by injection, the mold can be easily drawn out by disposing the positive ribs 810 in the vertical direction.

The discharge humidification medium housing will be described in more detail with reference to the drawings.

In this embodiment, a housing in which the discharge humidifying medium 55 is installed among the humidifying medium 50 is defined as the discharge humidifying medium housing 1400 .

In this embodiment, the discharge humidifying medium housing 1400 is disposed on the discharge passage 107 . The discharge humidifying medium housing 1400 may be installed in the top cover assembly 230 . The discharge humidifying medium housing 1400 may be manufactured integrally with the top cover assembly 230 .

In this embodiment, the discharge humidifying medium housing 1400 is manufactured as a structure separate from the top cover assembly 230 . The discharge humidifying medium housing 1400 is disposed below the top cover assembly 230 . The discharge humidifying medium housing 1400 may be detachably assembled to the top cover assembly 230 . In this embodiment, the discharge humidifying medium housing 1400 is mounted on the visual body 210 .

The top cover assembly 230 forms a part of the water supply passage 109 and exposes a water supply cap 1430 to be described later to the user.

In the discharge humidifying medium housing 1400, air may pass through the outside, and water may pass through the inside. Air is passed from bottom to top and water is passed from top to bottom.

The discharge humidification medium housing 1400 provides a discharge flow path 107 through which air passes to the outside, and a water supply flow path 109 through which water passes inside.

The discharge humidifying medium housing 1400 includes an upper housing 1410 , a lower housing 1420 , and a water supply cap 1430 . The discharge humidifying medium 55 is disposed between the upper housing 1410 and the lower housing 1420 .

A plurality of voids are formed in the upper housing 1410 and the lower housing 1420 .

The upper housing 1410 is formed in a donut shape as a whole.

The upper housing 1410 includes an upper frame 1412 disposed in the center, an upper housing opening 1415 formed in the center of the upper frame 1412 and providing a water supply passage 109, and the upper It includes an upper outer frame 1414 spaced apart from the inner frame 1412 and disposed outside, and an upper mesh frame 1416 connecting the inner frame 1412 and the upper outer frame 1414.

The lower housing 1420 is formed in a donut shape as a whole.

The lower housing 1420 includes a lower inner frame 1422 disposed in the center, a lower housing opening 1425 formed in the center of the lower inner frame 1422 and providing a water supply passage 109 , and the lower inner frame 1422 . It includes a lower outer frame 1424 spaced apart from the frame 1422 and disposed outside, and a lower mesh frame 1426 connecting the lower inner frame 1422 and the lower outer frame 1424.

The shapes of the upper housing 1410 and the lower housing 1420 correspond to each other.

The upper housing opening 1415 and the lower housing opening 1425 communicate with each other.

The upper housing 1410 and the lower housing 1420 are assembled to each other. In this embodiment, the upper housing 1410 and the lower housing 1420 are fitted. To this end, fitting protrusions 1411 and 1413 are formed in any one of the upper housing 1410 and the lower housing 1420, and fitting grooves 1421 and 1423 are formed in the other.

In this embodiment, fitting projections 1411 and 1413 are formed in the upper housing 1410 , and the fitting groove 1421 is formed in the lower housing 1420 . The fitting projections are formed on the upper frame 1412 and the upper outer frame 1414, respectively. The fitting grooves are formed in the lower inner frame 1422 and the lower outer frame 1424, respectively.

The water supply cap 1430 may be coupled to at least one of the upper housing 1410 and the lower housing 1420 . In this embodiment, the water supply cap 1430 is detachably fitted with the lower housing 1420 . Unlike the present embodiment, the water supply cap 1430 may be detachably installed in the upper housing 1410 .

A coupling protrusion 1437 and a coupling groove 1427 are formed for separable coupling of the water supply cap 1430 and the lower housing 1420 .

A coupling protrusion 1437 is formed in any one of the water supply cap 1430 or the lower housing 1420 , and a coupling groove 1427 is formed in the other one. In this embodiment, a coupling protrusion 1437 is formed on the water supply cap 1430 , and a coupling groove 1427 is formed on the lower housing 1420 .

The coupling protrusion 1437 and the coupling groove 1427 form a fitting coupling with respect to the horizontal direction.

The coupling protrusion 1437 is formed to protrude outward in the radial direction of the water supply cap 1430 . The coupling groove 1427 is formed to open toward the center of the lower housing 1420 .

Three coupling protrusions 1437 are arranged at equal intervals, and coupling grooves 1427 are formed corresponding thereto. In addition, a coupling protrusion engaging portion 1428 forming a mutual engagement with the coupling protrusion 1437 is formed in the coupling groove 1427 . The engaging projection engaging portion 1428 provides mutual engagement with respect to the radial direction of the lower housing 1420 .

The coupling protrusion engaging portion 1428 may be formed to protrude inward in the radial direction of the lower housing 1420 .

The user can couple the coupling protrusion 1437 and the coupling groove 1427 by inserting the water supply cap 1430 into the lower housing opening 1425 and rotating it clockwise. In the process in which the coupling protrusion 1437 is coupled to the coupling groove 1427 , the coupling protrusion 1437 rides over the coupling protrusion locking part 1428 to form a "click" operation sound and a feeling of operation.

Meanwhile, a water supply structure 1440 is formed in the discharge humidifying medium housing 1400 to temporarily store water supplied and drain the stored water downward.

The water supply structure 1440 is disposed on the water supply passage 109 and includes a reservoir 1441 for temporarily storing water, and for draining water from the water supply reservoir 1441 to the water tank 300 . and a water inlet 1445 .

The lever 1441 may be formed in any one structure. In this embodiment, the water supply reservoir 1441 is formed by combining a plurality of structures.

The water supply reservoir 1441 may be formed in at least one of an upper housing 1410 , a lower housing 1420 , and a water supply cap 1430 disposed on the water supply passage 109 . The lever 1441 may be formed by coupling with at least one of the upper housing 1410 , the lower housing 1420 , and the water supply cap 1430 disposed on the water supply passage 109 .

In this embodiment, the water supply reservoir 1441 is formed through the combination of the lower housing 1420 and the water supply cap 1430 .

The lower housing 1420 includes a reservoir base 1442 and a reservoir wall 1444 .

The reservoir base 1442 and the reservoir wall 1444 are formed on the lower inner frame 1422 .

The reservoir base 1442 is horizontally disposed, and the discharge humidifying medium 55 is positioned above the reservoir base 1442 . The reservoir base 1442 and the lower mesh frame 1426 are connected.

The reservoir wall 1444 is formed to protrude upward from the reservoir base 1442 . The lower housing opening 1425 is disposed on the inside of the reservoir wall 1444 , and the discharge humidifying medium 55 is disposed on the outside. The water supply cap 1430 is located inside the reservoir wall 1444 .

The water supply reservoir 1441 is formed between the inside of the reservoir wall 1444 , the upper side of the reservoir base 1442 , and the outside of the water supply cap 1430 .

A water supply port 1445 , a fitting groove 1423 , and a coupling groove 1427 are formed in the reservoir base 1442 . The water supply port 1445 and the fitting groove 1423 are disposed inside the reservoir wall 1444 , and the coupling groove 1427 is disposed outside the reservoir wall 1444 .

The water supply port 1445 is formed in a slit shape. The water supply port 1445 is formed to be opened in the vertical direction. The water supply port 1445 is formed in an arc shape when viewed in a plan view. The water supply port 1445 is formed along the inner boundary of the reservoir wall 1444 .

The width of the slit forming the water supply port 1445 is 0.7 to 0.8 mm, and the length is not limited.

The water supply port 1445 has a wide upper cross-section and a narrow lower cross-section when viewed from a vertical cross-section. The cross section of the water supply port 1445 is formed in the shape of a hopper with a pointed bottom when viewed from the vertical direction.

The water supply port 1445 may block the flow of air through this cross-sectional shape, and allow water to drain downward.

When the humidification cleaning device is operated, air flows from the humidification passage 106 to the discharge passage 107 and may be partially discharged through the water supply port 1445 . However, when water is stored in the water supply reservoir 1441 , air is not discharged through the water supply port 1445 . This is because the weight of water stored in the water reservoir 1441 is greater than the pressure of air.

When the cross section of the water supply port 1445 is formed wide, air may be discharged, and in this process, the water stored in the water supply reservoir 1441 is blown upwards.

The water supply structure 1440 according to the present embodiment can prevent the water from the water supply reservoir 1441 from being scattered in the opposite direction to the water supply even when water is supplied when the humidification cleaning device is operated.

By adjusting the capacity of the water supply reservoir 1441, it is possible to prevent air from being discharged from the water supply port 1445. For example, the pressure caused by the weight of the water stored in the water supply reservoir 1441 may be greater than the wind pressure that can be discharged through the water supply port 1445 .

In addition, when the width of the water supply port 1445 manufactured in the form of a slit is formed to be narrow, air can flow to the discharge humidifying medium 55 by resistance. When the air gap of the discharge humidifying medium 55 is larger than the cross-sectional area of the water supply port 1445, air flows toward the discharge humidifying medium 55 having a low resistance. On the other hand, when water is stored in the water supply reservoir 1441 , the water is drained through the water supply port 1445 by its own weight.

As such, it is possible to prevent air from being discharged through the water supply port 1445 in various ways.

When the user supplies water over the water supply cap 1430 , the supplied water is temporarily stored in the water supply reservoir 1441 . The water stored in the water supply reservoir 1441 is drained downward through the water supply port 1445 . The water of the water supply reservoir 1441 may be drained through the coupling groove 1427 formed in the reservoir base 1442 . Water from the water supply reservoir 1441 may be drained through the lower housing opening 1425 .

When more water than the capacity of the water supply reservoir 1441 is supplied, it may overflow outside the reservoir wall 1444 . Even if water overflows out of the reservoir wall 1444 , the supplied water falls or flows down to the visual body 210 . The water flowing down along the visual body 210 is also guided to the inside of the water tank 300 .

The humidification cleaning device according to the present embodiment has the advantage that water can be supplied to the water tank 300 regardless of the operation.

In the present embodiment, the discharge humidification medium housing 1400 is disposed on the lower side of the top cover assembly 230 , but unlike this embodiment, the humidification and cleaning device can be configured without the configuration of the top cover assembly 230 . That is, the discharge humidification medium housing 1400 in which the water supply cap 1430 is disposed is exposed to the outside, and water is poured into the water supply cap 1430 to realize upper water supply.

Hereinafter, with reference to FIGS. 6, 7 and 24, the flow of water during upper water supply will be described in more detail.

Water supplied from the upper part passes through the top cover assembly 230 and falls down.

In the present embodiment, the water that has fallen from the top cover assembly 230 does not directly fall to the water surface of the water tank 300 , but at least a part of it falls to the upper part of the watering housing 800 .

When the humidification cleaning device is operating in the humidification mode (when the watering housing is rotated), the water supplied from the upper part falls on the watering housing 800 and then scatters to form a rain view.

When the humidification cleaning device is stopped or is operating in a clean mode (when the watering housing is stopped), the water supplied from the upper part flows into the water tank 300 riding the watering housing 800 .

That is, regardless of the operation of the humidification cleaning device, it is possible to minimize the direct drop of the water supplied from the upper part to the water surface of the water tank 300 , thereby minimizing the noise of falling water.

Due to the characteristics of water, water flowing along the bottom of the discharge humidifying medium housing 1400 among the water supplied from the upper part may directly fall to the water surface. However, since it is small, it forms only a fraction of the total noise. In particular, after the water condensed on the bottom surface of the discharge humidifying medium housing 1400 falls to some extent, it may be absorbed into the discharge humidifying medium 55 by the air flow of the humidifying passage 106 .

The water supplied from the upper part falls to the watering housing cover 860 of the watering housing 800 .

The watering housing cover 860 has a larger diameter than the diameter formed by the water supply ports 1445 so that the water supplied to the upper part of the watering housing cover 860 can fall.

The watering housing cover 860 is disposed below the water supply port 1445 . In addition, the watering housing cover 860 is disposed below the upper housing opening 1415 and the lower housing opening 1425 .

That is, most of the water supplied through the upper water supply falls to the watering housing cover 860 .

When the watering housing 800 is rotating, the water supplied from the upper part is scattered radially outward from the watering housing cover 860 . A protrusion 861 is formed on the watering housing cover 860 in order to effectively disperse the water supplied from the upper part. A plurality of the protrusions 861 are disposed along the edge of the watering housing cover 860 . The protrusion 861 protrudes outward in the radial direction of the watering housing cover 860 .

When the watering housing 800 rotates, the water supplied from the upper part is separated into droplets from the protrusion 861 .

The droplets separated from the projection 861 collide with the inner surface of the visual body 210 . To this end, the watering housing cover 860 is preferably disposed on the same horizontal line as at least a portion of the visual body 210 . Considering that the scattered droplets fall by gravity, it is preferable to be located at an intermediate height of the visual body 210 .

The protrusion 861 is positioned higher than the second injection holes 412 and 413 .

A rain view is produced by the droplets scattered from the protrusion 861 . Through the rain view formed during upper water supply, the user can confirm that water is being supplied normally. The upper water supply can be confirmed not only through a visual effect such as a rain view, but also through a sound generated when scattered droplets collide with the visual body 210 .

The rain view sound generated during upper water supply is different from the sound through the injection hole 410 . The rainbow sound generated during upper water supply is larger than the rainbow sound generated through amniotic fluid and is irregularly formed.

Meanwhile, during upper water supply, droplets of various sizes are scattered from the watering housing cover 860 .

In the case of a large droplet, it flies from the projection 861 to the inside of the visual body 210 by its own weight. In the case of a large droplet, a relatively constant trajectory (S1, see FIG. 30) is formed by its own weight.

The trajectory S1 is different from the trajectory S3 (refer to FIG. 31 ) of water sprayed from the injection hole 410 .

The trajectory S3 of the water sprayed from the second injection holes 412 and 413 is different from the trajectory S1 scattered from the protrusion 861 . The S1 trajectory is formed to be higher than the S3 trajectory.

In the case of a small droplet, it is more affected by the air flow formed in the humidification flow path 106 than the effect by its own weight.

So, in the case of small droplets, they can be floated in the humidification passage 106 . Since the blower fan 24 is affected by wind pressure and gravity at the same time, the trajectory may be irregular.

In the case of a small droplet, a phenomenon is produced that floats in the humidification passage 106 and is pulled near the watering housing 800 .

The watering wings 850 of the watering housing 800 may attract floating droplets. The air flow by the watering blade 850 draws the floating or scattered droplets toward the surface of the watering housing 800 .

The watering wings 850 may attract droplets scattered from the watering housing cover 860 to form a water film S2 . During upper water supply, the water film generated around the watering housing 800 may appear differently depending on the amount of water supplied to the upper portion.

However, the water film is characterized in that it is formed symmetrically with respect to the watering housing 800 .

30 is an exemplary view showing the flow of water inside the air wash module during upper water supply, FIG. 31 is an exemplary view showing the trajectory of water sprayed through the 2-1 nozzle, and FIG. 32 is the 2-2 injection hole It is an exemplary view showing the trajectory of the water sprayed through, and FIG. 33 is an exemplary view showing the spray line.

The rain view produced by the air wash module 200 will be described in more detail.

Rain view means the same effect as rain falling outside the window. Rainview refers to the effect of rainwater forming. In this embodiment, an effect such as rain or a rain effect is produced inside the visual body 210 .

When the rain view is produced, droplets of various sizes are formed. The watering blade 850, the first injection hole 411, the 2-1 injection hole 412, the 2-2 injection hole 413, the watering housing cover 860, the projection 861 and the blowing fan 24 ) of the air flow is a rainbow directing means for generating droplets.

The first injection hole 411 , the 2-1 injection hole 412 , and the 2-2 injection hole 413 are used when the water pumped from the watering unit 400 is sprayed. A rain view is produced by the water sprayed from the first injection hole 411 , the 2-1 injection hole 412 , and the 2-2 injection hole 413 .

The watering housing cover 860 or the protrusion 861 scatters water falling during upper water supply to produce a rain view.

The wind pressure or air volume by the blowing fan 24 may crush the sprayed or scattered droplets to a smaller size. The air flowed by the blowing unit 20 may further refine the droplets while passing through the water tank humidification medium 51 .

The air flowed by the blowing unit 20 may refine the air falling from the humidification passage 106 . Since the air by the blowing unit 20 moves in the opposite direction to gravity, the air falling by its own weight and the falling droplets collide with each other to be miniaturized.

The droplets generated by the above-described rainbow directing means may flow or float in the humidification passage 106 . The droplets of the humidification passage 106 may humidify the flowing air, and may form droplets on the inner surface of the visual body 210 .

The water droplets formed on the inner surface of the visual body 210 may be moved along the inclination of the inner surface of the visual body 210 .

The visual body 210 is inclined toward the water tank 300 . The visual body 210 has a wide upper side and a narrow lower side. Therefore, it is possible to extend the residence time of the droplets flowing along the visual body 210, and through this, it is possible to extend the rain view production time. In addition, it is possible to suppress the droplets formed through the inclination of the visual body 210 from flowing down. The droplet may be maintained in a state formed on the visual body 210 by the surface tension of the droplet. In addition, the air flow of the blowing unit 20 can suppress the droplet from flowing down.

In addition, a water-repellent coating may be formed on the inner surface of the visual body 210 . When the water-repellent coating is formed, it is possible to prevent the droplets from spreading widely, and the shape of the droplets can be formed to be more round.

When water is formed on the visual body 210, the water formed on the visual body 210 may be projected or reflected on the surface of the display 160 (refer to FIGS. 2 and 4). When the water condensed on the visual body 210 flows down, the same effect appears on the display 160 as well.

In the visual body 210, the actual droplet moves from the top to the bottom along the slope, and from the outside to the inside. The droplets reflected from the surface of the display 160 move from the bottom to the top, and from the outside to the inside, opposite to the display inclination.

Therefore, at the boundary where the visual body 210 and the display 160 meet, a phenomenon in which the actual droplet and the reflected droplet merge is produced. This directing can make the user more effectively recognize the rain view.

34 is an exemplary view showing the position of the second injection hole according to the second embodiment of the present invention.

In this embodiment, unlike the first embodiment, three second injection ports are disposed.

The three second injection holes are arranged at intervals of 120 degrees. The three second injection holes are composed of a 2-1 injection hole 412 , a 2-2 injection hole 413 , and a 2-3 injection hole 414 .

Unlike the first embodiment, the second and third injection holes 414 may form a third injection line L3.

The 2-3th injection hole 414 may be disposed at a different height from the 2-1th injection hole 412 or the 2-2nd injection hole 413 . The 2-3th injection hole 414 may overlap the watering housing cover and form a wider injection angle.

Hereinafter, since the rest of the configuration is the same as that of the first embodiment, a detailed description thereof will be omitted.
