The display module 160 is supported on the outer visual body 214. The inner edge of the display module 160 is supported by the upper inner body ring 126. The display module 160 is positioned above the air guide 170. The display module 160 may be integrally formed with the connector 260.

The display module 160 is positioned above the air guide 170. The display module 160 may be disposed between the upper outer body 128 and the upper inner body 140. The display module 160 covers the upper inner body 128 and the upper inner body 140 such that the user can not see the upper outer body 128 and the upper inner body 140. The inner and outer sides of the display module 160 are preferably sealed to prevent water from penetrating between the upper outer body 128 and the upper inner body 140.

The inner side of the display module 160 is supported by the upper inner body 140 and the outer side thereof is supported by the outer visual body 218.

In this embodiment, the display 160 is formed in a ring shape. Unlike the present embodiment, the display 160 may be formed in an arc shape. The surface of the display 160 may be formed of a material capable of reflecting light or a material capable of reflecting light.

Thus, 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. When the water formed in the visual body 210 flows down, the display 160 has the same effect.

This effect gives the user a visual stimulus, and the user can intuitively recognize that the humidification is being performed. The water droplet image projected on the display 160 has a functional effect of not only the emotional effect that gives a refreshing feeling to the user but also the humidifying state.

The upper surface of the display 160 is formed obliquely. The display 160 is formed to be inclined to the user side. Therefore, the inside is high and the outside is low.

Next, each configuration of the air wash module 200 will be described.

The air wash module 200 provides humidification for filtered air. The air wash module 200 may implement a lane view in the humidification channel 106. The air wash module 2000 injects and circulates water in the water tank 300. The air wash module 200 converts water into small droplets and rinses the filtered air again through the scattered droplets When washing the filtered air through the scattered water, humidification and filtration are once again performed.

The air wash module 200 includes a humidification connection passage 105, a humidification passage 106, a discharge passage 107 and a water supply passage 109.

The air wash module 200 includes a water tank 300, a watering unit 400, a humidifying medium 50, a visual body 210, a top cover assembly 230, and a handle 180.

The handle 180 is coupled to the visual body 210, rotated by the visual body 210, and stored in the visual body 210. Only the air wash module 200 can be easily lifted through the handle 180 and can be separated from the air clean module 100.

The humidification connection passage 105 is disposed outside the water tank 300 and can guide air into the water tank 300. The humidification connection passage 105 is disposed outside the visual body 210 and can guide air into the visual body 210.

The humidification connection passage 105 may be disposed outside at least one of the water tank 300 and the visual body 210 and may guide the air into the water tank 300 or the visual body 210 .

The discharge passage 107 may be disposed between the top cover assembly 230 and the visual body 210. The discharge passage 107 may be disposed in at least one of the top cover assembly 230 and the visual body 210.

In this embodiment, a discharge passage 107 is formed at the outer edge of the top cover assembly 230, and a water supply passage 109 is disposed at the center of the inside of the top cover assembly 230.

In the humidifying and cleaning apparatus according to the present embodiment, power is supplied to the air clean module 100, and the air wash module 200 receives power through the air clean module 100.

Since the air wash module 200 is detachable with respect to the air clean module 100, the air clean module 100 and the air wash module 200 are provided with detachable power supply structures.

Since the air clean module 100 and the air wash module 200 are detachably assembled through the upper body 120, the upper body 120 is provided with a connector for supplying power to the air wash module 200, (260).

The top cover assembly 230 of the air wash module 200 is provided with an operation unit and a display that require power. The air wash module 200 is provided with a top connector 270 detachably connected to the connector 260. The top connector 270 is disposed in the top cover assembly 230.

In this embodiment, since the top cover assembly 230 can be detached, the inner surface of the visual body 210 or the inner surface of the water tank 300 can be easily cleaned.

The top cover assembly 230 has a water supply passage 109 formed therein and a discharge passage 107 formed between the top cover assembly 230 and the visual body 210. The top cover assembly 230 is detachably mounted to the visual body 210. The top cover assembly 230 includes a top connector 270 electrically connected to the connector 260.

When the top cover assembly 230 is mounted, the top connector 270 is mounted above the connector 260. The top cover assembly 230 receives electricity from the connector 260 through the top connector 270.

A water level indicator (not shown) for indicating the water level of the water tank 300 is disposed around the water supply channel 109. Thus, the user can check the water level of the water tank 300 which is visible when the water is watered. By disposing the water level display portion on the copper line for watering the user, it is possible to prevent the user from excessively supplying the water, and to prevent the water from overflowing in the water tank 300.

The level indicator is disposed in the top cover assembly 230. The detachable power supply structure of the top connector 270 and the connector 260 allows effective construction of the upper water supply.

The water tub 300 is detachably mounted on the upper body 120. The watering unit 400 is disposed inside the water tank 300 and is rotated inside the water tank 300.

The water tank 300 includes a water tank body 320 in which water is stored, an air wash inlet 31 formed in a side surface of the water tank body 320, And a water bath body extension 380 coupled to the visual body 210.

In the present embodiment, the water tank body 320 is formed in a cylindrical shape having an open upper side. Unlike the present embodiment, the water tank body 320 may be formed in various shapes.

The water tank body extension part 380 extends upward from the water tank 300. The water tank body extension portion 380 forms the air wash inlet 31. The air wash inlet 31 is formed between the water tank body extensions 380.

The air wash inlet 31 is formed on a side surface of the water tank body 320. The air wash inlet 31 is formed 360 degrees forward with respect to the water tank body 320. The air wash inlet 31 communicates with the humidifying connection passage 105.

The water tank extender (380) guides the water flowing down from the inner side of the visual body (210) into the water tank (300). Dripping noise can be minimized by guiding the water flowing down from the visual body 210.

The water tank extender (380) is fastened to the lower end of the visual body (210).

In this embodiment, the air wash inlet 31 is formed through the structure of the water tank body 320. The water tank body extension unit 380 may be disposed on the visual body 210 to form the air wash inlet 31. [ A part of the plurality of water tank body extensions 380 is disposed in the water tank 300 and the rest of the water tank body extensions 380 is disposed in the visual body 210 to form an air wash inlet 31). In addition, unlike the present embodiment, the air wash inlet 31 can be formed in a separate structure from the visual body 210 and the water tank 300. Also, unlike the present embodiment, an opening surface is formed in the visual body 210 to form an air wash inlet 31, and an opening surface may also be formed in the water tank 300 to form the air wash inlet 31.

That is, the air wash inlet 31 may be disposed in at least one of the water tank 300 and the visual body 210. The air wash inlet 31 may be formed through a combination of the water tank 300 and the visual body 210. The air wash inlet 31 may be disposed between the water tank 300 and the visual body 210 after the air wash inlet 31 is disposed in a separate structure separated from the water tank 300 and the visual body 210. The air wash inlet 31 may be formed through a combination of the water tank 300 and the visual body 210.

The air wash inlet 31 is disposed on the side of the air wash module 200 and is connected to the humidification channel 106. The air wash inlet 31 may be connected to or connected to the humidification connection passage 105.

The watering unit (400) has a function of supplying water to the humidifying medium (50). The watering unit 400 has a function of visualizing the humidification process. The watering unit 400 has a function of implementing a lane view inside the air wash module 200.

The watering unit 400 sucks the water inside the water tank by rotating the water ring housing 800, sucks the sucked water upward, and injects the pumped water outward in the radial direction. The watering unit 400 includes a watering housing 800 that sucks water inward, sucks the sucked water upward, and then discharges the sucked water in a radially outward direction.

In this embodiment, the water ring housing 800 is rotated to spray water. Water may be sprayed by using a nozzle instead of the water ring housing 800, unlike the present embodiment. Water can be supplied to the humidifying medium 50 by spraying water from the nozzle, and the rain view can be similarly implemented. According to the embodiment, water may be sprayed from the nozzle and the nozzle may be rotated.

The water sprayed from the water ring housing 800 sweeps the humidifying medium 50. The water sprayed from the water ring housing 800 may be sprayed toward at least one of the visual body 210 and the humidifying medium 50.

The water sprayed toward the visual body 210 may implement a lane view. The water sprayed toward the humidifying medium 50 is used to humidify the filtered air. Water may be sprayed toward the visual body 210 to implement a rain view, and water flowing in the visual body 210 may be wetted with the humidifying medium 50.

In this embodiment, a plurality of jetting openings having different heights are arranged in the watering housing 800. The water ejected from any one jetting port forms a droplet on the inner surface of the visual body 210 to implement the lane view and the water discharged from the other jetting port wets the humidifying medium 50 to be used for humidification.

The water ring housing 800 injects water toward the inner surface of the visual body 210 and the water flows down along the inner surface of the visual body 210. A droplet of water droplets is formed on the inner surface of the visual body 210, and the user can see the droplet through the visual body 210.

In particular, the water flowing from the visual body 210 is used to humidify the humidifying medium 50 by wetting it. The humidifying medium 50 is wetted by the water sprayed from the watering housing 800 and the water flowing from the visual body.

The visual body 210 is coupled to the water tank 300 and is located above the water tank 300. At least a part of the visual body 210 is formed of a material capable of viewing through the inside.

The display module 160 may be disposed outside the visual body 210. The display module 160 may be coupled to either the visual body 210 or the upper body 120.

The display module 160 is disposed on the line of sight of the lane view. In the present embodiment, the display module 160 is disposed on the upper body 120.

When the air wash module 200 is mounted, the outer surface of the visual body 210 is brought into close contact with the display module 160. At least a part of the surface of the display module 160 may be formed or coated with a material reflecting light.

The droplet formed on the visual body 210 is also projected on the surface of the display module 160. Thus, the user can observe the movement of the droplet in two places of the visual body 210 and the display module 160.

The water tank 300 is formed with an air wash inlet 31 through which air is communicated. The air wash inlet 31 is located between the connection passage 103 and the humidification passage 106. The air wash inlet 31 is an outlet of the connection passage 103 and an inlet of the humidification passage 106.

The filtered air supplied from the air clean module 100 flows into the air wash module 200 through the air wash inlet 31.

The humidifying medium 50 includes a water bath humidifying medium 51 disposed at an inlet of the humidification channel 106 and a discharge humidifying medium 55 disposed at an outlet of the humidification channel 106. The outlet of the humidification channel (106) and the inlet of the discharge channel (107) are connected to each other. Therefore, the discharge humidifying medium 55 may be disposed in the discharge flow path 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 in which humidification is performed is defined between the water tank humidifying medium 51 and the discharge humidifying medium 55, the connecting flow path 103 and the discharge flow path 107 are naturally defined.

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

In the present embodiment, the water tank humidifying medium 51 is disposed in the air wash inlet 31 of the water tank 300.

The water tank humidifying medium 51 may be located on at least one of the same plane, outside, or inside as the air wash inlet 31. It is preferable that the water tank humidifying medium 51 is located inside the air wash inlet 31 because water is humidified for humidification.

It is preferable that water flowing down after wetting the water tank humidifying medium 51 is stored in the water tank 300. It is preferable that water flowing down after wetting the water tank humidifying medium 51 is disposed so as not to flow out of the water tank 300.

Thus, the water tank humidifying medium 51 provides humidification for the filtered air passing through the air wash inlet 31.

The filtered air is humidified by the water that is spontaneously evaporated in the humidifying medium (50). The natural evaporation refers to the evaporation of water in the absence of additional heat. As the contact with air increases, as the flow rate of air increases, the lower the pressure in the air, the more natural evaporation is promoted. The natural evaporation may be referred to as natural vaporization.

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

The water tank humidifying medium 51 and the discharge humidifying medium 55 are not always wetted with water stored in the water tank 300 because they are separated from the water stored in the water tank 300. [ That is, the water tank humidifying medium 51 and the discharge humidifying medium 55 are wetted only when operated in the humidifying mode, and when the water tank humidifying medium 51 and the discharge humidifying medium 55 are operated in the air clean mode, As shown in Fig.

The water tank humidifying medium 51 covers the air wash inlet 31 and air flows into the water tank 300 through the water tank humidifying medium 51.

The discharge humidifying medium 55 may be disposed at the outlet of the humidification flow path 106 or the inlet of the discharge flow path 107.

In this embodiment, the discharge humidifying medium 55 is arranged to cover the upper portion of the visual body 210. The discharge humidifying medium 55 is mounted on the visual body 210. The discharge humidifying medium 55 may be coupled to the bottom surface of the top cover assembly 230, unlike the present embodiment.

The discharge humidification medium 55 covers the discharge flow passage 107 and humidified air flows through the discharge humidification medium 55 and then into the discharge flow passage 107.

FIG. 6 is a perspective view of the top cover assembly in the air wash module shown in FIG. 2, and FIG. 7 is an exploded perspective view of the top cover assembly and the discharge humidifying medium housing shown in FIG.

In this embodiment, the top cover assembly 230 is detachably mounted to the visual body 210. The top cover assembly 230 not only provides a discharge flow path 107 but also a water supply flow path 109 for supplying water.

In this embodiment, the top cover assembly 230 is positioned above the discharge humidification medium 55. The discharge humidification medium housing 1400 in which the discharge humidification medium 55 is disposed is disposed and the top cover assembly 230 is disposed in the discharge humidification medium housing 1400 in the present embodiment. The discharge humidifying medium housing 1400 is mounted on the upper part of the visual body 230. The top cover assembly 230 is mounted on the upper portion of the discharge humidification medium housing 1400. The top cover assembly 230 may be integrally assembled with the discharge humidification medium housing 1400. In this embodiment, the top cover assembly 230 and the discharge humidifying medium housing 1400 are manufactured.

The top cover assembly 230 is mounted on the visual body 210 and does not apply a load to the discharge and humidification medium housing 1400.

The discharge humidification medium housing 1400 is disposed inside the discharge humidification medium 55 and covers the upper portion of the visual body 210. The water supply flow passage 109 is configured to pass through the discharge humidification medium housing 1400. The discharge flow path 107 is configured to pass through the discharge humidifying medium housing 1400.

The top cover assembly 230 includes a top cover grill 232 forming a discharge flow path 107 and a water supply flow path 109, an operation module 240 installed on the top cover grill 232, And a top connector 270 that provides power or signals to the controller 240.

The top cover grill 232 includes a grill discharge port 231 forming at least part of the discharge flow path 107 and a grill water port 233 forming at least part of the water supply flow path 109. The grill discharge port 231 and the grill feed port 233 are formed to be open in the vertical direction. The grill water inlet 233 is disposed at the center of the inside of the top cover grill 232 and the grill outlet 231 is disposed outside the grill water inlet 233.

The top cover grill 232 is detachably mounted to the visual body 210. The top cover grill 232 is mounted inside the visual body 210.

The operation module 240 is coupled to the top cover grill 232. The operation module 240 can receive a user's operation signal. The operation module transmits the level information to the user. A water supply channel (109) is disposed in the operation module (240). The operation module 240 is electrically connected to the top connector 270 and receives power from the top connector 270.

The operation module 240 includes an operation housing 250 coupled to the discharge grill 232 and having at least a portion of the water supply flow passage 109 formed therein, an input unit 245 disposed in the operation housing 250, A water level indicator 247 disposed in the operation housing 250 and an operation controller (not shown) for controlling the water level indicator 247 and the input unit 245.

The operating housing 250 includes an upper operating housing 242 and a lower operating housing 244.

The operation module 240 is provided with a water supply passage 109. A part of the water supply channel (109) is formed in the vertical direction at the center of the operation module (240). The operation module 240 may be provided with an operation water inlet 241 for forming at least a part of the water supply flow passage 109. The operation water inlet 241 is disposed inside the operation housing and is opened in the vertical direction.

The operation module 240 further includes an upper water supply guide 236. The upper water supply guide 236 guides the upper water supplied to the operation water inlet 241. Some of the operation housing 250 is inclined to form the upper water supply guide 236.

At the time of the upper water supply, the user can not see the water level in the water tank 300, but can instantaneously confirm the water level elevated through the water level indicator 247 disposed around the operation water inlet 241. Since the user can confirm the water level through the water level display part 247 during the upper water supply, the user can adjust the upper water supply flow rate.

The water that has been supplied to the upper portion passes through the discharge humidification medium housing 1400 and falls into the humidification flow path 106. Particularly, the water that has been supplied to the upper part drops to the upper part of the water ring housing 800 without falling directly onto the water surface of the water tank 300.

When the watering housing 800 is rotating at the time of the upper water supply, the upper watered water is scattered over the watering housing 800, thereby forming a separate rain view.

That is, not only the rain view can be formed through the water sprayed from the watering unit 400, but also the rain view can be formed through the water supplied in the upper part.

8 is a cross-sectional view of the air wash module shown in Fig. 4, Fig. 9 is an enlarged view of G shown in Fig. 8, Fig. 10 is a perspective view showing the installed state of the water ring housing shown in Fig. 11 is a front view of Fig. 10, Fig. 12 is a sectional view taken along the line MM of Fig. 11, Fig. 13 is a plan view of Fig. 12, Fig. 14 is an exploded perspective view of the water ring housing shown in Fig. Fig. 16 is a front view of Fig. 14, and Fig. 17 is a cross-sectional view taken along the line NN of Fig.

The water ring housing 800 is a structure for spraying water stored in the water tub 300. The water ring housing 800 has a structure for efficiently pumping water stored in the water tank 300.

The water ring housing 800 is rotated by receiving the rotational force of the water ring motor 42. When the water ring housing 800 rotates, the water stored in the water tank 300 is sucked into the water ring housing 800 and then pumped upward. The water pumped into the water ring housing 800 is discharged through the injection port 410.

The water ring housing (800) is provided with a pumping means. The water pumping means pumps the water of the water tank 300 upward. The method of pumping water in the water tank can be variously implemented.

For example, water may be pumped through the amphibious pump and then injected.

For example, water can be pumped by rotating the water ring housing and creating friction or mutual interference with water during rotation.

In this embodiment, a structure for pumping water through the rotation of the water ring housing 800 is proposed. In this embodiment, the pumping means is a pumping groove 810 that pushes water upwards through friction or mutual interference with water.

A positive groove 810 is formed on the inner surface of the water ring housing 800 as a positive number means. The positive groove 810 improves the positive water efficiency. The positive groove 810 protrudes from the inner side of the watering housing 800. The positive groove 810 is formed to extend vertically in the vertical direction. The positive groove 810 is disposed radially with respect to the watering motor shaft 43 or the power transmission shaft 640.

The lower end of the water ring housing 800 is separated from the bottom of the water tub 300 by a predetermined distance to form a suction interval 801 (H1). The water in the water tub 300 is sucked into the water ring housing 800 through the suction interval 801.

The water level H2 of the water tank 300 in which the water ring housing 800 can spray water is formed to be higher than the suction interval H1 and lower than the jetting port 410. [ The water level H2 includes a high water level.

When the water level H2 is lower than the suction interval H1, since water is not sucked, a positive number is not possible. When the water level H2 is higher than the jetting port 410, the water injected into the jetting port 410 is not sprayed.

The water ring housing 800 is formed so that its lower side is opened. The water ring housing 800 is cup-shaped. The water ring housing 800 has an inverted cup shape. A housing space 805 is formed in the water ring housing 800.

A column 35 of the water tank 300 is located inside the water ring housing 800 and a power transmission module 600 is disposed inside the column 35. The water ring housing 800 is disposed to surround the column 35.

The water ring housing 800 is formed to have a flat section extending toward the upper side. The column 35 is formed such that its flat cross section is reduced toward the upper side. The shape of the water ring housing 800 and the column 35 is a shape for effectively pumping water. The volume of the housing space 805 increases toward the upper side.

When the water ring housing 800 is rotated, the water sucked into the inside of the water ring housing 800 is brought into close contact with the inner circumferential surface of the water ring housing 800 by centrifugal force. The positive groove 810 formed in the inner circumferential surface of the water ring housing 800 provides rotational force to the water sucked in.

The water ring housing (800) is provided with an injection port (410) for discharging sucked water to the outside. In the present embodiment, the injection port 410 is arranged to discharge water in the horizontal direction. The water pumped through the injection port 410 is discharged to the outside.

In this embodiment, the water discharged from the injection port 410 may be injected into the visual body 210.

The number of the injection ports 410 may be adjusted according to design conditions. In the present embodiment, a plurality of the jetting ports 410 are arranged in the watering housing 800 with a height difference. An ejection port disposed above the water ring housing 800 is defined as a second ejection port and an ejection port disposed in the middle of the water ring housing is defined as a first ejection port.

The water jetted from the first jet opening is used for humidification. The water jetted from the second jetting port is used for humidification, watering, and lane view.

Water sprayed from the second jetting port may flow down to wet the water tank humidifying medium.

After the water jetted from the second jetting hole hits the visual body, it is scattered to form a rainbow view. After the water jetted from the second jetting hole hits the visual body, it is converted into fine droplets, and these droplets can be used for watering to wash filtered air.

When the water ring housing 800 is rotated at a speed higher than the first rotation speed, water may be jetted from the first jetting port. When the water ring housing 800 is rotated at a speed higher than the second rotation speed, water may be jetted from the second jetting port.

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

Only when the water ring housing 800 is rotated at a high speed, water is discharged from the second jetting port. The water ring housing 800 is rotated at a normal speed so that water is not discharged through the second jetting port. The first jetting orifice discharges water at every stage in which the watering housing is routinely operated.

A plurality of the second ejection openings may be disposed. A plurality of the first injection openings may be arranged.

When the water ring housing 800 is rotated at the normal rotation speed, the water pumped up is raised higher than the minimum first jetting port. When the water ring housing 800 is rotated at a high speed, the pumped water rises above the height of the second jetting port.

A plurality of the second jetting ports may be disposed in the circumferential direction of the water ring housing 800. A plurality of the first jetting ports may also be disposed in the circumferential direction of the watering housing 800.

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

The water discharged from the injection port 410 strikes the inner surface of the visual body 210 and moves along the inner surface of the visual body 210 because the water ring housing 800 is rotated.

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

In the visual body 210, a droplet is formed by the injected water, and the droplet flows downward.

In this embodiment, the water ring housing 800 is composed of three parts. Unlike the present embodiment, the water ring housing 800 can be made of one or two parts.

The lower end of the water ring housing 800 is spaced apart from the bottom of the water tub 300 by a predetermined distance.

The watering housing 800 includes a first watering housing 820, a second watering housing 840, a watering housing cover 860 and a watering power transmission portion 880.

The water ring housing 800 is assembled with the power transmission shaft 640 and a structure for receiving the rotational force from the power transmission shaft 640 is disposed. In the present embodiment, the water ring housing 800 is assembled with the power transmission shaft 640 through the water ring power transmission portion 880 and the water ring housing cover 860. The water ring housing 800 is coupled to the power transmission shaft 640 at two places and receives rotational force from two places.

Unlike the present embodiment, the water ring housing 800 is coupled to the power transmission shaft 640 at one place, and can receive the rotational force at one combined position.

Also, unlike the present embodiment, the water ring housing 800 can receive rotational force in a manner other than the power transmission shaft. For example, the rotational force of the water ring motor can be transmitted in a belt-pulley manner. For example, the rotational force of the water ring motor can be transmitted in a gear engagement manner. For example, the rotational force of the watering motor can be transmitted in a chain manner. For example, the rotational force of the water ring motor can be transmitted in a clutch manner.

In this embodiment, the first coupler 610 is of a male type and the second coupler 620 is of an arm type. In the present embodiment, the first coupler 610 is detachably coupled to the second coupler 620. The second coupler 620 may be coupled to the first coupler 610 in a manner different from the present embodiment.

The water ring motor 42 is installed in the upper body 120. The watering motor 42 is located above the blowing motor 22 and is spaced apart from the blowing motor 22. The water tank 300 is mounted inside the upper body 120. When the water tub 300 is mounted on the upper body 120, the first and second couplers 610 and 620 are connected so as to transmit power. The water ring motor shaft 43 of the watering motor 42 is arranged to face upward. A first coupler 610 is installed at the upper end of the water ring motor shaft 43.

Each of the constitutions of the water ring housing 800 will be described as follows.

The first water ring housing 820 is formed by opening the upper side and the lower side, respectively, and a positive groove 810 is formed on the inner side. The lower end of the first water ring housing 820 is separated from the bottom of the water tank 300 by a predetermined distance to form a suction interval 801.

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

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

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

Unlike the present embodiment, the first water ring housing 820 and the second water ring housing 840 can be integrally manufactured. Also, unlike the present embodiment, the first water ring housing 820 and the water ring housing cover 860 can be integrally manufactured.

The upper end surface of the first water ring housing 820 is formed wider than the lower end surface. The first water ring housing 820 forms an inclination in the vertical direction. The first watering housing 820 may have a conical shape with a lower end face narrowed.

A positive groove 810 is formed in the first watering housing 820. The amphibious grooves 810 are formed in the vertical direction. The positive groove 810 is disposed radially about the watering motor shaft 43. A plurality of the positive grooves 810 may be disposed and protrude toward the axis center of the watering housing 800.

The lower end of the first water ring housing 820 is spaced apart from the inner bottom surface of the water tank 300 to form a suction gap 801. The upper end of the first watering housing 820 is engaged with 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 water ring housing 820 and the second water ring housing 840 are assembled through a screw connection. A thread 822 is formed on the upper outer peripheral surface of the first water ring housing 820 and a thread 842 is formed on the lower inner peripheral surface of the second water ring housing 840. [

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

A first barrier 823 for limiting the movement of the second watering housing 840 is formed below the first screw 822. The first barrier 823 is formed in the circumferential direction of the first water ring housing 820. The first barrier 823 is formed in a strip shape and protrudes to the outside of the first water ring housing 820.

The first barrier 823 is brought into close contact with the lower end of the second water ring housing 840 when the first water ring housing 820 and the second water ring housing 840 are assembled. The first barrier 823 is further protruded 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 leakage of water 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 mounting rib 824 is disposed to fix the position of the first packing 825. The packing mounting ribs 824 may be disposed on an extension of the first threads 822. The packing mounting rib 824 may be part of the first thread 822.

Thus, the first threads 822 may be formed in a plurality and discontinuously dispersed, and one of them may be the packing mounting ribs 824.

A first jetting port 411 is disposed in the first watering housing 820. In the present embodiment, two of the first ejection openings 411 are disposed. The two first injection openings 411 are formed so as to face each other.

The first jetting port 411 communicates the inside and outside of the first watering housing 820. In this embodiment, the inner opening area of the first ejection opening 411 is formed to be wider than the outer opening area. The first jetting port 411 supplies water to the water tank humidifying medium 51, and soaks the water tank humidifying medium 51. The first jetting port 411 may be jetted toward the water tank humidifying medium 51.

A water ring vane 850 is formed on the outer circumferential surface of the second watering housing 840. The water ring vane 850 can flow humidifying air. When the water ring housing 800 rotates, the water ring vane 850 can draw air around it. The water ring vane 850 functions not only as a function of flowing air but also as a rain view directing means for making droplets finer.

The air in the humidification flow path 106 in which the water ring housing 800 is disposed flows mostly toward the discharge flow path 107 due to the flow of the air blowing fan 24 but the air around the water ring vane 850, Can flow. The water ring vane 850 can locally produce an air flow as opposed to an air flow by the blowing fan 24. Air may flow in the same direction as the flow by the blowing fan 24 depending on the shape of the water ring vane 850. At this time, the air around the water ring housing 800 can be collected on the surface of the water ring housing 800 by the rotation of the water ring vane 850.

The air flow by the water ring vane 850 has the effect of flowing water particles around the water ring housing 800 to the water tank 300. The rotation of the water ring vane 850 has the effect of generating air volume and attracting water particles around the water ring housing 800.

The air flow by the water ring vane 850 serves to collect the falling water toward the water ring housing 800 when the water drops from the water supply channel 109 to the upper portion of the water ring housing 800 do.

When water is supplied through the water supply flow passage 109 when the water ring housing 800 is rotated, water may be scattered irregularly on the surface of the water ring housing 800. The air flow by the water ring vane 850 can collect water particles scattered at the time of water supply toward the surface of the water ring housing 800.

The second water ring housing 840 is formed with second jetting ports 412 and 413. The second injection ports 412 and 413 inject water toward the visual body 210. In the present embodiment, two of the second ejection openings 412 and 413 are disposed. One of the second jetting ports is referred to as a second-1 jetting port 412 and the other is defined as a second-2 jetting port 413.

The second-1 injection port 412 and the second -2 ejection port 413 are arranged to face in different directions. In the present embodiment, the second-1 injection port 412 and the second-2 ejection port 413 are disposed so as to face each other. The second-first injection port 412 and the second-second injection port 413 may be arranged symmetrically with respect to the power transmission shaft 640.

When viewed in plan, the second-1 injection port 412 and the second-2 injection port 413 form an angle of 180 degrees. When viewed in plan, the second-1 injection port 412 is disposed between the water ring blades 850. The second-second jet opening 413 is also disposed between the water ring vanes 850.

When viewed from the front, the height of the second-1 injection port 412 and the second-2 ejection port 413 is equal to or higher than that of the water ring vane 850. A part of the trajectories S3 and S4 of the water sprayed from the second-1 injection port 412 and the second-2 ejection port 413 is located within the turning radius of the circular saw blade 850.

Therefore, when the water ring housing 800 is rotated, some of the water injected from the second-1 injection port 412 and the second-2 ejection port 413 collides with the water ring vane 850 and is scattered.

In this embodiment, the second-1 injection port 412 and the second-2 ejection port 413 form a predetermined height difference. The second-1 injection port 412 and the second-2 ejection port 413 are not arranged at the same height.

The second-1 injection port 412 and the second-2 ejection port 413 form a height difference, so that the position of the water hitting the visual body 210 can be set differently. Therefore, when the water ring housing 800 is rotated, the water dispersed in the second-1 ejection port 412 and the water ejected from the second-2 ejection port 413 pass through different paths.

A trajectory S3 of the water that strikes the inner surface of the visual body 210 at the second jetting ports 412 and 413 is defined as a jetting line.

The injection line formed by the second-1 injection port 412 is defined as a first injection line L1 and the injection line in which the second-second injection port 413 is formed is defined as a second injection line L2 do.

remind In the visual body 210  The injection line formed does not mean only a straight line. The injection line At the nozzle Discharged  A curve may be formed according to the angle.

Further, the thickness of the injection line is Jet In diameter  And thus can be formed differently. In other words Jet Diameter  The larger the injection line is formed Diameter  If it is small, it may be formed thin.

In this embodiment, after the water dispersed in the second-1 injection port 412 passes through one of the visual bodies 210, the second- Water will pass. That is, two injection lines L1 and L2 are formed on the inner surface of the visual body 210, and it is possible to more effectively recognize that the water is sprayed through the visual production.

When water is ejected from two second ejection openings arranged at a constant height, only one ejection line is formed. When the water ring housing 800 is rotated at a high speed, the phase difference may be extremely short even if the first and second second jetting openings 142 and 143 are positioned in opposite directions. In this case, water may flow down from one injection line, which may cause optical illusions.

On the other hand, in the case of forming two jet lines, since the position where the water hits is different, the sound generated by collision is formed differently. That is, the sound generated in the first injection line and the sound generated in the second injection line are differently formed. This acoustic difference allows the user to visually recognize that the watering housing 800 is rotating.

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

The difference in sound through the plurality of jetting lines is effective for effectively conveying an operational situation to a low vision or hearing impaired person. Also, it is easy to confirm that the humidifying and cleaning device is operating even in the absence of light.

At least one of the second ejection openings 412 and 413 may be partially covered with the watering housing cover 860. In the present embodiment, the second-1 injection port 412 is disposed in a fully opened state, and the second-2 ejection port 413 is partially overlapped with the water ring housing cover 860 to be obscured.

The water ring housing cover 860 is positioned in front of the second-second jet opening 413. The water ring housing cover 860 partially covers the upper side of the second-second jet opening 413.

In this embodiment, when the water ring housing cover 860 is engaged with the second water ring housing 840, it overlaps with a part of the second-second jet opening 143. In this embodiment, the water ring housing cover 860 is used as a diffusion member. Unlike the present embodiment, a separate diffusion member for diffusing water sprayed from the injection port may be disposed.

For example, when injecting the water ring housing, it is possible to intentionally form burrs and to diffuse the water sprayed through the burrs.

The water injected from the second-second injection port 413 may interfere with the diffusion member, and the injection angle and width may be changed. The water interfering with the diffusion member is pulled toward the diffusion member by surface tension.

In the second-1 injection port 412 where no overlap with the diffusion member is formed, the diameter of the injection port and the diameter of the discharged water are formed similarly. In the second-second jet opening 413 having an overlap with the water ring housing cover 860, water is injected in a wider range than the diameter of the jet opening.

The trajectory of water injected from the second-1 injection port 412 is defined as S3, and the trajectory of water injected from the second-second injection port 413 is defined as S4.

The second-2 injection port 413 is positioned slightly higher than the 2-1-injection port 412. The second-second jet opening 413 partially overlaps with the cover body borders 863 of the water ring housing cover 860 as a diffusion member.

The water injected through the second-second injection port 413 is injected while interfering with the cover body bordering 863, so that the water to be injected becomes finer and injected.

The droplet ejected from the second-2 ejection port (413) is formed to be smaller than the droplet ejected from the second-1 ejection port (412). The trajectory S4 of the droplet jetted from the second-2 jet opening 413 is formed above the locus S3 injected from the second-1 jet opening 412. [ The droplet ejected from the second-2 ejection port 413 is ejected more widely than the droplet ejected from the second-1 ejection port 412. Therefore, the width of the injection line L2 formed by the overlapped 2-2 injection port 413 is wider than that of the injection line L1 formed by the 2-1 injection port 412.

Meanwhile, the water ring vane 850 can flow air around the water ring housing 800, but can also fine water jetted from the jet opening 410.

In this embodiment, the water jetted from the second jetting ports 412 and 413 collides with the water ring vane 850 to be refined. The water ring vane 850 can make water into a mist shape.

The water ring vane 850 does not miniaturize all the water jetted from the second jetting ports 412 and 413. Part of the water jetted from the second jetting ports (412) and (413) collides with the water ring vane (850).

The water jetted from the two jetting ports 412 and 413 forms a predetermined trajectory S3 so that the water ring 850 that is rotated bumps against the water on the trajectory S3. That is, part of the water jetted from the second jetting ports 412 and 413 is scattered by colliding with the water ring vane 850, and the remaining water does not collide with the water ring vane 850 and flows into the inside of the body of the visual body 210 It hits the side.

The water impinging on the water ring vane 850 is scattered widely in the humidification channel 106, not in a specific direction. For example, the water scattered in the water ring vane 850 may wet the discharge humidifying medium 55. The water scattered in the water ring vane 850 can be formed on the visual body 210. [ The water scattered in the water ring vane 850 can float on the humidification channel 106.

The water finely fined by the water ring vane 850 is effective to produce a rainbow view. The micronized droplets are formed in a small droplet shape on the inner surface of the visual body 210.

Instead of the water ring vane 850, a rain view directing means may be disposed between the water ring housing 800 and the visual body 210. Water jetted from the jetting port 410 may be scattered by colliding against the rainview directing means. For example, a mesh may be disposed between the visual body 210 and the watering housing 800 as a lane view directing means. The water jetted from the cylindrical housing 800 can be scattered after being crushed into smaller droplets while passing through the mesh.

Meanwhile, the lane view generated in the humidification channel 106 can generate negative ions by a Lenard effect.

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

During the process of rendering the lane view, the droplets are scattered and hit, and a large amount of anions are produced in this process.

When water injected from the first injection port 411 collides with the structure, negative ions can be generated by the Leonard effect.

Also, when water sprayed from the second injection ports 412 and 413 hits the visual body 210, negative ions can be generated by the Leonard effect.

Further, when the water jetted from the second jetting ports 412 and 413 hits the water ring vane 850, negative ions can be generated by the Leonard effect.

Further, at the time of the upper water supply, when the droplets scattered at the watering housing cover 860 hit the various structures, negative ions can be generated by the Leonard effect.

As described above, in this embodiment, droplets of various sizes for rendering the rain view have the effect of generating negative ions in the production process. The generated negative ions are discharged to the room through the discharge passage 107.

On the other hand, within the second watering housing 840, a water film-restraining rib 870 for suppressing the rotation of the water film is formed. The water film rotational flow refers to a flow that is rotated along the inner surface of the water ring housing 800.

The water groove 810 of the first water ring housing 820 is for forming the water film rotation flow, and the water film retaining rib 870 is for suppressing the water film rotation flow.

The first water ring housing 820 is configured to pump the water to the second water ring housing 840 so as to positively generate the water film rotation flow, As the rotational motion of the water film is not formed, the injection through the second injection ports 412 and 413 is easy.

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

Further, as the large amount of water stays in the second watering housing 840, the vibration of the watering housing 800 is greatly formed. The water pumped up to the second watering housing 840 must be jetted rapidly through the second jetting ports 412 and 413 to minimize the eccentricity of the watering housing 800 and minimize the vibration thereof .

The water-film-restraining ribs 870 minimize the rotation of the water film, thereby minimizing eccentricity and vibration of the water-ring housing 800.

The water-restraining ribs 870 protrude from the inner surface of the second watering housing 840. In the present embodiment, the water-barrier ribs 870 protrude toward the power transmitting shaft 640. The water-film-restraining ribs 870 are formed in a direction crossing the water film rotation flow.

The water film rotation flow flows spirally or circularly along the inner surface of the second watering housing 840. It is preferable that the water film restriction ribs 870 are formed in the vertical direction.

In this embodiment, the water-barrier ribs 870 are formed in the vertical direction. A plurality of the water-barrier ribs 870 may be formed. In this embodiment, the three water-curtain suppressing 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 water ring housing.

In this embodiment, the projecting 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 can be variously changed according to the embodiment.

In this embodiment, the water-film-restraining rib 870 is formed in connection with the water-ring power transmission portion 880. The water film suppressing ribs 870 and the water ring power transmitting portion 880 can be separated from the present embodiment.

In this embodiment, the water film-retaining rib 870 is connected to the water ring power transmission portion 880, so that the metal mold can be simplified.

The water ring power transmission unit 880 is configured to transmit the rotational force of the power transmission shaft 640 to the water ring housing 800.

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

In this embodiment, the water ring power transmission portion 880 is fabricated integrally with the second water ring housing 840. Unlike the present embodiment, the water ring power transmitting portion 880 may be manufactured separately and then assembled to the second water ring housing 840.

The water ring power transmission portion 880 includes a bushing mounting portion 882 located at the shaft center of the watering housing 800 and a watering connection portion 882 connecting the bushing mounting portion 882 and the watering housing 800. [ (884). In the present embodiment, the bushing mounting portion 882, the water ring connecting portion 884, and the second watering housing 820 are formed by injection molding.

The water ring connection portion 884 is formed in a rib shape. The water ring connection portions 884 are arranged radially with respect to the axis center, and a plurality of water ring connection portions 884 are formed.

In this embodiment, the water ring connection portion 884 is fabricated integrally with the water film retaining rib 870. The water ring connection portion 884 and the water film restriction rib 870 are connected to each other.

The power transmitting shaft 640 is installed to pass through the bushing mounting portion 882.

The lower side of the bushing mounting portion 882 is open. The bushing 90 is inserted through the lower open side of the bushing mounting portion 882.

The bushing mounting portion 882 and the bushing 90 can be separated in the vertical direction. The bushing mounting portion 882 and the bushing 90 form mutual engagement in the rotation direction.

For this purpose, a bushing latching portion 93 is formed on one of the bushing mounting portion 882 and the bushing 90, and a bushing latching groove 883 is formed on the other. In this embodiment, the bushing 90 is formed with a bushing engagement portion 93, and the bushing attachment portion 882 is formed with a bushing engagement groove 883.

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

The bushing latching portion 93 is inserted into the bushing latching groove 882 and inserted.

The bushing mounting portion 882 and the bushing 90 may be integrally formed, unlike the present embodiment. Since the bushing 90 is formed of a metal material, when the second watering housing 840 is manufactured, the bushing 90 may be disposed in the mold, and then the second watering housing material may be injected into the body to be integrally formed.

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

The bushing 90 is coupled with the power transmission shaft 640 to receive a rotational force. The bushing 90 is preferably formed of a metal material. If it is not a rigid metal material, abrasion may occur and this will cause vibration.

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

The bushing 90 reduces vibration when the water ring 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 water ring housing 800 is located at the bushing 90, the vibration of the water ring housing 800 can be significantly reduced during rotation.

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

The power transmission shaft 640 is formed with a shaft end portion 642 to support the bushing 90. The diameter of the upper side is smaller and the diameter of the lower side is larger with respect to the axial end (642).

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

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

When the shaft end 642 is worn, the bushing 90 moves causing vibration. Further, when the shaft end portion 642 is worn, the bushing 90 can be inclined or moved, thereby causing misalignment with the power transmission shaft 640. [ In addition, when the bushing 90 and the power transmission shaft 640 are misaligned, eccentricity is generated when the bushing 90 and the power transmission shaft 640 are rotated.

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

In this embodiment, the water ring housing cover 860 is assembled with the power transmission module 600. The water ring housing cover 860 may be separated from the power transmission module 600. [

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

The watering housing cover 860 includes a cover body 862 covering an upper opening of the second watering housing 840 and a second watering cover 860 extending downward from the cover body 862, A cover body bordering portion 863 surrounding the upper end of the housing 840, a packing mounting rib 864 formed below the cover body 862 and spaced apart from the cover body bordering portion 863 by a predetermined distance, A shrinking portion 866 fixed to the power transmitting shaft 640 and a reinforcing rib 868 connecting the shrinking portion 866 and the packing mounting 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 water ring 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 water ring housing 800 is not limited to a specific shape.

The cover body borders 863 form the rim of the cover body 862. [ The cover body borders 863 are formed in a ring shape and are integrally formed with the cover body 862. The cover body borders 863 have a plurality of protrusions 861 formed on the outer surface thereof and the protrusions 861 are formed 360 degrees along the circumferential direction. The projection 861 provides a gripping feeling to the user when detaching the watering housing cover 860.

In addition, the protrusion 861 can effectively scatter water dropped during the upper water supply. The water dropped through the upper water supply falls to the watering housing cover 860 and flows to the cover body bordering 863 by the rotation of the watering housing 800. [ And then sprayed on the inner side of the visual body 210 after being separated from the protrusions 861 in the form of water drops. The protrusion 861 can effectively scatter the water that has been supplied.

The expansion mounting ribs 864 are located inside the cover body borders 863 and spaced apart from the cover body borders 863 by a predetermined distance. A second packing 865 is provided between the cover body borders 863 and the packing mounting ribs 864.

And can seal the space between the watering housing cover 860 and the second watering housing 840 through the second packing 865. The water in the housing space 805 is prevented from leaking through the first packing 825 and the second packing 865 so that the pressure of the water discharged through the injection port 410 can be kept constant.

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 keep the pressure of the water discharged from the jetting port 410 constant.

That is, when water is leaked from the water ring housing 800, water may not be sprayed from the jet opening 410 even if the water ring housing 800 is rotated.

The cover body borders 863 and the second watering housing 840 can be screwed together. In this embodiment, the watering housing cover 860 and the second watering housing 840 are tightly assembled.

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

The shrinking portion 866 and the power transmitting shaft 640 can be screwed. For this purpose, a thread 643 for screw connection with the water ring housing cover 860 is formed on the outer circumferential surface of the upper end of the power transmission shaft 640.

The shrinking portion 866 may be formed with a thread for assembling with the power transmission shaft 640. In this embodiment, a shaft fixing member 867 is disposed in the shrinking portion 866 and the shaft fixing member 867 is integrally formed in the shrinking portion 866. In this embodiment, the shaft fixing member 867 is a nut.

Unlike the water ring housing cover 860, the shaft fixing member 867 is made of a metal material. The power transmission shaft 640 is made of a metal material and the portion that is screwed with the power transmission shaft 640 is made of a metal material to prevent wear or damage at the time of tightening. When the entire water ring housing cover 860 is formed of a metal material or when the shrinking portion 866 is formed of a metal material, it is preferable to form a thread on the shrinking portion 866 itself.

The water ring housing cover 860 is formed larger than the diameter of the second water ring housing 840. Only the watering housing cover 860 is exposed, and the second watering housing 840 and the first watering housing 820 are not exposed.

So that at least a part of the water supplied to the water supply flow path 109 can be dropped into the water ring housing cover 860. When the water ring housing 800 is rotated, the water dropped into the water ring housing cover 860 is radially outwardly ejected from the surface of the water ring housing cover 860.

The rotated water ring housing cover 860 is capable of effecting the effect that the water is squeezed along the rotating direction and water is dropped from the umbrella. Particularly, water droplets can be peeled off from the plurality of projections 861 arranged in the circumferential direction of the water ring housing cover 860.

The water sprayed in the direction of rotation in the water ring housing cover 860 hits the inner surface of the visual body 210 and can produce a lane 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 flow down.

In the present embodiment, the water ring groove 810 is designed in such a manner that water in the water tank 300 can be effectively pumped. In this embodiment, the water ring groove 810 is positioned lower than the jetting port 410. In particular, the water ring groove 810 is formed lower than the first ejection opening 411.

The water ring groove 810 turns the horizontal rotational force against water in the vertical direction. When the watering groove 810 is formed, water can be more effectively pumped in the vertical direction.

In this embodiment, the water ring groove 810 is formed on the inner surface of the water ring housing 800 and protrudes inward. The water ring groove 810 is formed to extend in the vertical direction. Unlike the present embodiment, the water ring groove 810 may be formed in a zigzag shape. In this embodiment, since the first water ring housing 82 is manufactured by injection molding, the water ring groove 810 can be arranged in the vertical direction to easily draw the metal mold.

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

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

In the present embodiment, the discharge humidification medium housing 1400 is disposed on the discharge flow path 107. The discharge humidification medium housing 1400 may be installed in the top cover assembly 230. The discharge and humidification medium housing 1400 may be manufactured integrally with the top cover assembly 230.

In this embodiment, the discharging humidification medium housing 1400 is made of a separate structure from the top cover assembly 230. The discharge humidification 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 flow passage 109 and exposes a water supply cap 1430, which will be described later, to the user.

The discharging humidification medium housing 1400 may be configured such that air is allowed to pass outward and water can pass therethrough. Air is passed from the lower side to the upper side and water is passed from the upper side to the lower side.

The discharge and humidification medium housing 1400 provides a discharge flow passage 107 through which air flows outward and provides a water supply flow passage 109 through which water passes.

The discharge humidification 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.

The upper housing 1410 and the lower housing 1420 are formed with a plurality of voids.

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

The upper housing 1410 includes an upper inner frame 1412 disposed at the center and an upper housing opening 1415 formed at the center of the upper inner frame 1412 to provide a water supply flow path 109, An upper outer frame 1414 that is spaced apart from the inner frame 1412 and disposed at an outer periphery thereof and an upper mesh frame 1416 that connects the upper inner frame 1412 and the upper outer frame 1414 to each other.

The lower housing 1420 is generally formed in a donut shape.

The lower housing 1420 includes a lower inner frame 1422 disposed at the center, a lower housing opening 1425 formed at the center of the lower inner frame 1422 to provide a water supply flow passage 109, A lower outer frame 1424 that is spaced apart from the frame 1422 and disposed on the outer side and a lower mesh frame 1426 that connects 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 with each other. In the present embodiment, the upper housing 1410 and the lower housing 1420 are fitted together. To this end, one of the upper housing 1410 and the lower housing 1420 has the fitting protrusions 1411 and 1413 and the other fitting groove 1421 and 1423 is formed.

The fitting protrusions 1411 and 1413 are formed in the upper housing 1410 and the fitting groove 1421 is formed in the lower housing 1420 in this embodiment. The fitting protrusions are formed in the upper inner 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 releasably fitted to 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 detachable coupling of the water supply cap 1430 and the lower housing 1420.

One of the water supply cap 1430 and the lower housing 1420 has a coupling protrusion 1437 and the other coupling groove 1427 is formed. In this embodiment, a coupling protrusion 1437 is formed in the water supply cap 1430, and a coupling groove 1427 is formed in the lower housing 1420.

The engaging projections 1437 and the engaging grooves 1427 form a fitting engagement with respect to the horizontal direction.

The coupling protrusion 1437 protrudes radially outward of the water supply cap 1430. The coupling groove 1427 is formed to be open toward the center of the lower housing 1420.

Three of the engaging projections 1437 are arranged at equal intervals, and the engaging grooves 1427 are formed correspondingly. The engaging groove 1427 is formed with an engaging projection 1428 which engages with the engaging projection 1437. The engaging projection engaging portions 1428 provide mutual engagement with respect to the radial direction of the lower housing 1420. [

The engaging projection 1428 may protrude radially inward of the lower housing 1420.

The user can insert the water supply cap 1430 into the lower housing opening 1425 and turn the water supply cap 1430 clockwise to engage the coupling protrusion 1437 and the coupling groove 1427. The engaging projection 1437 engages with the engaging projection 1428 while the engaging projection 1437 engages with the engaging groove 1427 to form an operation sound and a feeling of operation.

On the other hand, the discharge humidifying medium housing 1400 is formed with a water supply structure 1440 for temporarily storing the water to be supplied and draining the stored water to the lower side.

The water supply structure 1440 includes a reservoir 1441 disposed on the water supply passage 109 for temporarily storing water and a water reservoir 1441 for discharging water from the water reservoir 1441 to the water tank 300 And a water supply port 1445.

The lever 1441 may be formed on any one of the structures. In this embodiment, the water supply reservoir 1441 is formed through the coupling of a plurality of structures.

The water supply reservoir 1441 may be formed on at least one of the upper housing 1410, the lower housing 1420 and the water supply cap 1430 disposed on the water supply flow path 109. The lever 1441 may be formed through engagement with at least one of the upper housing 1410, the lower housing 1420 and the water supply cap 1430 disposed on the water supply flow path 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 reseal broom 1444.

The reservoir base 1442 and the leisure broom 1444 are formed in the lower inner frame 1422.

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

The reservoir boss 1444 protrudes upward from the reservoir base 1442. The lower housing opening 1425 is disposed on the inside of the resilient bellows 1444 and the discharge humidifying medium 55 is disposed on the outside. The water supply cap 1430 is positioned inside the leisure broom 1444.

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

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

The water supply port 1445 is formed in a slit shape. The water supply port 1445 is formed to be open 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 leisure broom 1444.

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

The water supply port 1445 has a wide upper end surface and a narrower lower end surface when viewed in the vertical direction. The cross section of the water supply port 1445 is formed into a hopper shape having a sharp bottom when viewed in the up-and-down direction.

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

When the humidifying and cleaning apparatus is operated, the 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 reservoir 1441, air is not discharged through the water supply port 1445. The weight of the water stored in the water supply reservoir 1441 is larger than the air pressure.

If the cross section of the water supply port 1445 is wide, air may be discharged, and water stored in the water supply reservoir 1441 may be scattered upward.

The water supply structure 1440 according to the present embodiment can prevent the water from flowing in the water supply reservoir 1441 in the direction opposite to the water supply even when the water supply is performed when the humidifying and cleaning apparatus is operated.

The capacity of the water supply reservoir 1441 can be adjusted to prevent air from being discharged from the water supply port 1445. For example, the pressure of the water stored in the water supply reservoir 1441 may be made larger 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 formed in the slit shape is narrow, the air can be caused to flow to the discharge humidifying medium 55 by the resistance. When the discharge humidification medium 55 has a gap larger than the cross-sectional area of the water supply port 1445, the air flows toward the discharge humidification medium 55 with a small resistance. On the other hand, when water is stored in the water supply reservoir 1441, water is drained through the water supply port 1445 by its own weight.

In this manner, air can be prevented from being discharged through the water supply port 1445 by various methods.

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 can also be drained through the engagement groove 1427 formed in the reservoir base 1442. The water in the water reservoir 1441 can also be drained through the lower housing opening 1425.

If more water than the capacity of the water reservoir 1441 is supplied, it can overflow the reservoir 1444 and out. Even if the water overflows out of the leisure broom 1444, the water is dropped or flowed into the visual body 210. The water flowing along the visual body 210 is also guided into the water tank 300.

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

In this embodiment, the discharge humidifying medium housing 1400 is disposed below the top cover assembly 230. However, unlike the present embodiment, the humidifying and cleaning apparatus can be configured without 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 implement the upper water supply.

Hereinafter, the flow of water at the time of the upper water supply will be described in more detail.

The water that has been supplied to the upper part falls down through the top cover assembly 230.

In this embodiment, the water dropped 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 the water falls down onto the water ring housing 800.

When the humidifying / cleaning device is operating in the humidification mode (when the watering housing is rotated), the upper water supplied to the watering housing 800 is scattered and formed to form a lane view.

When the humidifying and cleaning device is in a stopped state or in a clean mode (when the watering housing is stopped), the upper water supplied flows into the water tub 300 on the watering housing 800.

That is, irrespective of the operation of the humidifying and cleaning device, it is possible to minimize the direct drop of the water that has been supplied to the water surface of the water tank 300, thereby minimizing the dropping noise.

Due to the characteristics of water, water flowing along the bottom surface of the discharge humidifying medium housing 1400 in the upper water supplied can be directly dropped to the water surface. However, this is only a small amount, so it only forms part of the total noise. Particularly, after the water formed on the bottom surface of the discharge humidifying medium housing 1400 has fallen to some extent, it can be absorbed into the discharge humidifying medium 55 by the air flow of the humidification flow path 106.

The upper water is dropped to the water ring housing cover 860 of the water ring housing 800. [

The diameter of the water ring housing cover 860 is formed to be larger than the diameter formed by the water supply ports 1445 so that water supplied by the water ring housing cover 860 can be dropped.

The water ring 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 upper watered water is scattered radially outward at the watering housing cover 860. A projection 861 is formed in the watering housing cover 860 to effectively scatter the water that has been supplied. The projections 861 are disposed along the edge of the water ring housing cover 860. The projection 861 protrudes radially outward of the water ring housing cover 860.

When the water ring housing 800 is rotated, the upper water supplied is separated into droplets from the protrusions 861.

The liquid separated from the protrusion 861 hits the inner surface of the visual body 210. For this, the watering housing cover 860 is preferably disposed on the same horizontal line as at least a part of the visual body 210. It is preferable to be located at a middle height of the visual body 210 in consideration of falling droplets due to gravity.

The projections 861 are positioned higher than the second ejection openings 412 and 413.

A lane view is produced by the droplets scattered by the projections 861. Through the lane view formed at the upper water supply, the user can confirm that the water supply is normally performed. The upper water supply can be checked not only by the visual effect such as the rain view but also by the sound generated when the scattered droplet hits the visual body 210.

The lane view sound generated during the upper water supply is different from the sound through the injection port 410. The lane view sound generated during the upper water supply is formed larger than the lane view sound generated through the positive water, and is irregularly formed.

On the other hand, in the upper water supply, droplets of various sizes are scattered in the watering housing cover 860.

In the case of a large droplet, the liquid droplets are transferred from the protrusion 861 to the inside of the visual body 210 by their own weight. In the case of a large droplet, a relatively constant locus S1 is formed by its own weight.

The trajectory S1 is different from the trajectory S3 of the water injected from the injection port 410. [

The trajectory S3 of the water jetted from the second jetting ports 412 and 413 is different from the trajectory S1 scattered by the protrusions 861. [ The S1 locus is formed to be higher than the S3 locus.

In the case of a small droplet, it is more influenced by the air flow formed in the humidification channel 106 than by the self weight.

Thus, in the case of a small droplet, it can float in the humidification channel 106. The influence of wind pressure and gravity of the air blowing fan 24 is simultaneously received, so that the locus may be irregular.

In the case of a small droplet, the phenomenon of being floated in the humidification channel 106 and pulled in the vicinity of the watering housing 800 is produced.

The water ring vane 850 of the water ring housing 800 can attract the droplets to be floated. The air flow by the water ring vane 850 attracts floating or scattered droplets to the water ring housing 800 surface side.

The water ring vane 850 may draw the droplets scattered in the water ring housing cover 860 to form the water film S2. The water film generated in the vicinity of the water ring housing 800 at the time of the upper water supply may be different depending on the amount of the water to be supplied.

However, the water film is formed symmetrically with respect to the water ring housing 800.

Fig. 30 is an exemplary view showing the flow of water in the air wash module at the time of the upper water supply, Fig. 31 is an illustration showing the locus of water injected through the 2nd-1st injection port, FIG. 33 is an exemplary diagram showing a spray line. FIG.

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

Lane view means the same effect as raining out the window. Rain-view means the effect of rainwater. In this embodiment, effects such as raining of the inside of the visual body 210 or effect of rain are produced.

When the lane view is rendered, droplets of various sizes are formed. The water ring housing cover 860, the protrusion 861, and the blowing fan 244, the water ring housing cover 860, the first jetting port 411, the second-1 jetting port 412, the second-2 jetting port 413, ) Is a rain view directing means for generating droplets.

The first jetting port 411, the second jetting port 412 and the second jetting port 413 are used to jet the water pumped from the watering unit 400. The lane view is rendered by the water jetted from the first jetting port 411, the second jetting port 412, and the second jetting port 413.

The water ring housing cover 860 or the protrusion 861 splashes the water to be dropped during the upper water supply to produce a rainbow view.

The wind pressure or the wind amount by the blowing fan 24 can crush jetted or scattered droplets to a smaller size. The air that has been flown by the air blowing unit 20 can pass through the water tank humidifying medium 51 to further refine the droplets.

The air flowed by the air blowing unit (20) can make the air falling in the humidification flow path (106) finer. Since the air by the air blowing unit 20 is moved in the direction opposite to the gravitational force, the air falling due to its own weight can collide with the falling droplets and can be made fine.

The droplets generated by the above-described rain view rendering means can flow or float in the humidification channel 106. The droplets of the humidification channel 106 can humidify the air to be flowed and can be formed in the form of water droplets on the inner side of the visual body 210.

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

The visual body 210 is formed to be inclined toward the water tub 300. The visual body 210 is wide on the upper side and narrow on the lower side. Thus, the residence time of the droplet flowing along the visual body 210 can be extended, thereby extending the rain view rendering time. In addition, it is possible to prevent the droplets formed through the inclination of the visual body 210 from flowing downward. The droplet can be maintained in the state of being formed in the visual body 210 by the surface tension of the droplet. Further, the air flow of the air blowing unit 20 can suppress the droplet from flowing downward.

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 droplet from spreading widely, and to make the shape of the droplet 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. When the water formed in the visual body 210 flows down, the display 160 has the same effect.

In the visual body 210, the actual droplet is moved from the upper side to the lower side along the inclination and from the outside to the inside. The liquid reflected on the surface of the display 160 is moved from the lower side to the upper side and from the outside to the inside in the reverse direction of the display tilt.

Thus, at the boundary between the visual body 210 and the display 160, a phenomenon that the actual droplet and the reflected droplets are combined is produced. This directive allows the user to recognize the lane view more effectively.

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

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

The three second injection openings are arranged at intervals of 120 degrees. The three second ejection openings include a second-first ejection opening 412, a second-second ejection opening 413, and a second-ejection opening 414.

Unlike the first embodiment, the second to third ejection openings 414 may form a third ejection line L3.

The second to third ejection openings 414 may be disposed at different heights from the second-first ejection openings 412 or the second-second ejection openings 413. The 2-3 th jetting port 414 overlaps with the watering housing cover, and can form a wider spray angle.

Since the remaining configuration is the same as that of the first embodiment, the detailed description will be omitted.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It should be understood that various modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention.
