However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various forms, and the embodiments are only for the purpose of more fully disclosing the present invention, so as to more fully suggest the scope of the present invention to those skilled in the art to which the present invention pertains, and the present invention is defined only by the scope of the claims. Like reference numerals refer to like structural elements throughout the specification.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Fig. 1 is a perspective view of a humidification purification device according to a first embodiment of the present invention, fig. 2 is an exploded perspective view of fig. 1, fig. 3 is an exploded front view of fig. 1, fig. 4 is a cross-sectional view taken along line B-B of fig. 3, and fig. 5 is a schematic view illustrating an air flow of the humidification purification device according to the first embodiment of the present invention.

The humidification purification device of the embodiment includes: an air cleaning module 100(air clean module); and an air wash module 200(air wash module) placed on the upper side of the air cleaning module 100.

The air cleaning module 100 filters the sucked external air and provides the filtered air to the air cleaning module 200. The air cleaning module 200 receives the filtered air, humidifies the filtered air to supply moisture, and discharges the humidified air to the outside.

The air cleaning module 200 includes a water tank 300 that stores water. Upon separation of the air wash module 200, the water tank 300 may be separated from the air cleaning module 100. The air wash module 200 is placed above the air cleaning module 100.

The user may separate the air wash module 200 from the air cleaning module 100 and sweep the separated air wash module 200. The user can sweep the interior of the air cleaning module 100 from which the air wash module 200 is separated. With the air cleaning module 200 separated, the upper side of the air cleaning module 100 is open to the user.

The air cleaning module 100 includes a filter assembly 10, which will be described later, and cleans the filter assembly 10 after separating it from the base 110.

The user may supply water to the air cleaning module 200. The air cleaning module 200 is provided with a water supply passage 109 so that water can be supplied from the outside to the water tank 300.

The water supply passage 109 is configured to be separated from the discharge passage 107 for discharging air. The water supply channel 109 is configured to supply water to the water tank as needed. For example, in the case where the air cleaning module 200 is operating, water can be supplied through the water supply passage. For example, even in a state where the air cleaning module 200 is coupled to the air cleaning module 100, water can be supplied through the water supply flow path. For example, in a state where the air cleaning module 200 is separated from the air cleaning module 100, water can be supplied through the water supply flow path.

The air cleaning module 100 and the air cleaning module 200 are connected by a connecting flow path 103. Since the air cleaning module 200 is detachably provided, the connection flow path 103 is dispersedly disposed between the air cleaning module 100 and the air cleaning module 200. Only when said air wash module 200 is placed in the air cleaning module 100, the flow path of the air wash module 200 and the flow path of the air cleaning module 100 can communicate with each other through the connection flow path 103.

The connection flow path formed in the air cleaning module 100 is defined as a cleaning connection flow path 104, and the connection flow path formed in the air cleaning module 200 is defined as a humidifying connection flow path 105.

The flow of air through the air cleaning module 100 and the air cleaning module 200 will be described in detail later.

The air cleaning module 100 and the air purge module 200 are described in more detail below.

The air cleaning module 100 includes: a base 110; a filter assembly 10 disposed on the base 110 for filtering air; and an air blowing unit 20 disposed on the base 110 for flowing air.

The air purge module 200 includes: a water tank 300 storing water for humidification, detachably placed in the air cleaning module 100; a watering unit 400(watering unit) disposed inside the water tank 300, spraying water of the water tank; a humidifying medium 50 which is wetted by the water sprayed from the watering unit 400 and supplies moisture to the flowing air; a visual body 210(visual body) coupled to the water tub 300 and formed of a material allowing the inside thereof to be seen; the head assembly 230 is detachably mounted on the visual body 210, and has a discharge passage 107 for discharging air and a water supply passage 109 for supplying water.

The air cleaning module 100 includes an intake flow path 101, a filter flow path 102, an air blowing flow path 108, and a cleaning connection flow path 104. The air sucked through the suction flow path 101 flows through the filter flow path 102 and the blowing flow path 108 to the cleaning connection flow path 104.

The air cleaning module 200 is provided with a humidification connection channel 105, a humidification channel 106, a discharge channel 107, and a water supply channel 109.

The cleaning connection flow path 104 of the air cleaning module 100 and the humidifying connection flow path 105 of the air cleaning module 200 are connected only when the air cleaning module 200 is placed in the air cleaning module 100.

The filtered air supplied through the humidification connection channel 105 of the air cleaning module 200 is discharged into the room through the humidification channel 106 and the discharge channel 107. The water supply channel 109 is configured to communicate with the humidification channel 106, but can receive only water supply without discharging air.

First, each structure of the air cleaning module 100 will be described.

The base body 110(base body) is composed of an upper body 120(upper body) and a lower body 130(lower body). The upper body 120 is stacked on the upper side of the lower body 130, and the upper body 120 and the lower body 130 are assembled.

Air flows toward the inside of the base 110.

The lower body 130 is provided with an intake flow path 101, a filtration flow path 102, and an air blowing flow path 108, and is provided with a structure for forming the intake flow path 101, the filtration flow path 102, and the air blowing flow path 108.

The upper body 120 is provided with a part of the connection flow path 103, and is provided with a structure for guiding the filtered air to the air cleaning module 200 and a structure for placing the air cleaning module 200.

The base 110 includes: a lower body 130 having an outer shape and a suction port 111 formed at a lower side thereof; an upper body 120 for forming a shape combined with an upper side of the lower body 130.

The filter assembly 10 is detachably assembled to the base 110.

The filter assembly 10 provides a filtering flow path 102 and performs filtering of external air. The filter assembly 10 is configured to be attachable to and detachable from the base 110 in a horizontal direction. The filter assembly 10 is disposed in such a manner as to intersect with the flow direction of air that flows upstream in the vertical direction. The filter assembly 10 is slidably moved in a horizontal direction to filter air flowing in an upper side in a vertical direction. The filter assembly 10 is disposed horizontally, and forms a filtration flow path 102 in the vertical direction.

The filter assembly 10 is slidable in a horizontal direction with respect to the base 110.

The filter assembly 10 includes: a filter case 12 disposed inside the lower body 130 to form a filtering flow path 102; a filter 14 detachably coupled to the filter housing 12, for filtering air passing through the filtering flow path 102.

The filter housing 12 communicates with the suction flow path 101 at the lower side and with the air blowing flow path 108 at the upper side. The air sucked through the suction flow path 101 flows through the filter flow path 102 to the air blowing flow path 108.

One side of the filter case 12 is opened in a direction intersecting the filter flow path 102. The filter 14 may be detachably coupled through the open face of the filter housing 12. The opening of the filter case 12 is formed facing in a lateral direction. The opening surface of the filter case 12 is disposed on the outer surface of the lower body 130. Thereby, the filter 14 is inserted through the side surface of the lower body 130 and positioned inside the filter housing 12. The filter 14 is disposed so as to intersect the filter flow path 102, and filters air passing through the filter flow path 102.

The filter 14 may be an electric dust collector filter that traps impurities in the air by charging an applied power source. The filter 14 may be formed of a material that traps impurities in the air by a filter member. Various structures may be configured in the filter 14. The scope of protection of the invention is not limited by the filtering means of the filter 14 or the filtering components of the filter.

The filtration flow path 102 is arranged in the same direction as the main flow direction of the humidification/purification device. In the present embodiment, the filter flow path 102 is arranged in the vertical direction, and causes air to flow in the direction opposite to the gravity. That is, the main flow direction of the humidification purification device is formed from the lower side toward the upper side.

An air blowing unit 20 is disposed above the filter case 12.

The upper side surface of the filter housing 12 is formed in an open state, and the air passing through the filter flow path 102 flows to the air blowing unit 20.

The air blowing unit 20 generates a flow of air. The air blowing unit 20 is disposed inside the base 110 and causes air to flow from the lower side to the upper side.

The blower unit 20 includes a blower fan case 150, a blower motor 22, and a blower fan 24. In the present embodiment, the blower motor 22 is disposed on the upper side, and the blower fan 24 is disposed on the lower side. The motor shaft of the air supply motor 22 is directed downward, and is assembled with the air supply fan 24.

The blower fan case 150 is disposed inside the base 110. The blower fan case 150 provides a flow path of the flowing air. The blower motor 22 and the blower fan 24 are disposed in the blower fan case 150.

The blower fan case 150 is disposed above the filter assembly 10 and below the upper body 120.

The blower fan case 150 forms the blower flow path 108 therein. The air blowing fan 24 is disposed in the air blowing passage 108. The air supply flow path 108 connects the filter flow path 102 and the clean connection flow path 104.

The blower fan 24 is a centrifugal fan that sucks air from below and discharges the air radially outward. The blower fan 24 discharges air radially outward and upward. The outer end of the blower fan 24 is formed radially upward.

The blower motor 22 is disposed above the blower fan 24 to minimize contact with the flowing air. The blower motor 22 is provided so as to be covered with a blower fan 24. The blower motor 22 is not located in the air flow path by the blower fan 24, and does not cause resistance to the air flowing by the blower fan 24.

The upper body 120 includes: an upper outer body 128(upper outer body) for forming the outer shape of the base 110, combined with the lower body 130; an upper inner body 140(upper inner body) disposed inside the upper outer body 128, the water tank 300 being inserted into the upper inner body 140, the upper inner body 140 providing a connection flow path 103; an air guide 170(air guide) combining the upper inner body 140 and the upper outer body 128 for guiding air toward the water tub 300.

Since the upper body 120 separates the connection flow path from the water tank insertion space, the water of the water tank 300 can be minimally flowed into the connection flow path. In particular, since the upper inner body is divided, the connection flow path is positioned outside the space for storing water, and the water can be prevented from flowing into the connection flow path.

The upper side of the upper inner body 140 is formed in an open state, and the water tank 300 is inserted into the upper inner body 140. The upper inner body 140 forms a part of the clean connecting flow path 104 into which filtered air flows.

The upper inner body 140 is formed with an upper inlet port 121 corresponding to the air purge inlet port 31. The inflow port 121 is not an essential structural element. It is sufficient that the upper body 120 has a shape in which the air purge inlet 31 is exposed to the connection flow path 103.

The air guide 170 guides the air supplied through the cleaning connection flow path 104 to the inflow port 121. The air guide 170 collects air rising along the outer side of the base 110 toward the inner side. The air guide 170 serves to switch the flow direction of air flowing from the lower side to the upper side. However, the air guide 170 minimizes the angle thereof to minimize the flow resistance of the air when switching the flow direction of the air.

The air guide 170 is formed in such a manner as to wrap the outer side of the upper inner body 140 by 360 degrees. The air guide 170 guides air to the water tank 300 in 360 degrees in all directions. The air guide 170 collects air guided along the outside of the lower body 130 to the inside and supplies the air to the water tank 300. With this configuration, the flow rate of the air supplied to the water tank 300 can be sufficiently ensured.

Accordingly, the air guide 170 includes: a guide portion 172 formed along the flow direction of the air; and a switching part 174 connected to the guide part 172 to switch a flow direction of the guided air.

The air guide 170 forms a connection flow path 103.

The guide 172 is formed in substantially the same direction as the filter flow path 102, and in the present embodiment, the guide 172 is formed in the vertical direction. The switching portion 174 is formed in a direction intersecting with the filtering flow path 102, and in the present embodiment, the switching portion 174 is formed in a substantially horizontal direction.

The transition portion 174 is formed at an upper side of the air guide 170. The transition portion 174 is preferably connected to the guide portion 172 by a curved structure.

Even if the switching portion 174 is formed in the horizontal direction, the air passing through the connection flow path 103 will flow in a substantially inclined upper direction. By forming the connection angle between the connection flow path 103 and the filtration flow path 102 to be close to the straight ahead direction, the flow resistance of air can be reduced.

The lower end of the guide portion 172 is fixed to the upper outer body 128. The upper end of the switching part 174 is fixed to the upper inner body 140.

A part of the cleaning connection flow path 104 is formed outside the upper inner body 140. The air guide 170 forms a part of the cleaning connection flow path 104. The air passing through the cleaning connection flow path 104 flows into the water tank 300 through the upper inlet 121 and the air purge inlet 31.

The upper inner body 140 is integrally formed in a basket (basket) shape. The upper inner body 140 is formed to have a circular cross section, and the cleaning connection passage 104 is formed in all directions of 360 degrees.

The air guide 170 is a structure that guides the filtered air to the clean connection flow path 104, and the air guide 170 may not be included according to an embodiment. The air guide 170 is used to couple the upper inner body 140 or the upper outer body 128.

The air guide 170 is formed in such a manner as to cover the upper inner body 140. In particular, the air guide 170 is formed to cover the inflow port 121, and guides the filtered air to the inflow port 121. The air guide 170 has a circular ring (donut) shape when viewed from above.

In this embodiment, the upper end of the air guide 170 is closely attached to the upper end of the upper inner body 140.

The upper side of the air guide 170 and the upper side of the upper inner body 140 are uniform when viewed from above. In this embodiment, an upper inner body ring 126(upper inner body) coupled to or closely attached to the air guide 170 is formed at an upper end of the upper inner body 140.

An inner body extension 148 is formed connecting the upper inner body 140 and the upper inner body ring 126. The inner body extension 148 is provided in plurality. An upstream inlet port 121 is formed between the inner body extension 148 and the upper inner body ring 126.

The inner body extension 148 is formed corresponding to the water tank body extension 380. When the water tank 300 is placed, the water tank body extension 380 is positioned inside the inner body extension 148. The inner body extension 148 and the water tub body extension 380 overlap each other inside and outside.

The upper end of the air guide 170 abuts or is coupled to the upper inner body ring 126. The lower end of the air guide 170 is closely attached or coupled to the upper outer body 128.

Thereby, the air flowing through the clean connection flow path 104 between the upper inner body 140 and the upper outer body 128 is guided to the inflow port 121.

The diameter of the upper inner body ring 126 is the same or similar to the diameter of the upper end of the air guide 170. The air guide 170 abuts the upper inner body ring 126 to prevent leakage of filtered air. The upper inner body ring 126 is disposed inside the air guide 170.

A handle 129 may be formed at the upper outer body 128. The air cleaning module 200 is placed on the upper body 120, and the entire humidification/purification device can be lifted by the handle 129.

The upper inner body 140 is formed therein with a water tank insertion space 125 to enable insertion of the water supply tank 300.

The cleaning connection flow path 104 is disposed on the outer side with respect to the upstream inlet 121, and the water tank insertion space 125 is disposed on the inner side. The air flowing along the clean connection flow path 104 passes through the upstream inlet 121. When the water tank 300 is placed in the water tank insertion space 125, the filtered air passing through the inlet port 121 flows into the water tank 300.

In addition, an outer visual body 214 is coupled to an upper side of the upper body 120.

The outer viewing body 214 is a structure of the viewing body 210, but is fixed to the upper body 120 in the present embodiment. Unlike the present embodiment, the outer visible body 214 may also be fixed to the air cleaning module 200. Unlike the present embodiment, the outer visible body 214 is a removable structure.

The outer visible body 214 is secured to the upper body 120. In this embodiment, the outer visible body 214 is combined with the upper outer body 128. The outer visible body 214 forms a continuous surface with the outer side surface of the upper outer body 128.

The outer viewing body 214 is formed of a material that allows viewing of the interior. The outer visible body 214 may be formed of a transparent or translucent material.

A display module 160 for displaying an action status to a user may be provided at least one of the air cleaning module 100 or the air cleaning module 200. In this embodiment, a display module 160 for displaying the operation state of the humidification/purification device to the user is provided on the base 110.

A display module 160 is disposed inside the outer visual body 214. The display module 160 is disposed in close contact with the inner surface of the outer visible body 214. The display module 160 has a circular ring shape when viewed from above. The water tank 300 is inserted into the inside of the display module 160.

The display module 160 is supported by the outer visible body 214. The inside edge of the display module 160 is supported by the upper inner body ring 126. The display module 160 is positioned on the upper side of the air guide 170. The display module 160 may be integrally fabricated with a connector 260 (connector).

The display module 160 is positioned on the upper side of 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 serves to cover between the upper outer body 128 and the upper inner body 140 so that a user cannot see between the upper outer body 128 and the upper inner body 140. In particular, in order to cut off water permeation between the upper outer body 128 and the upper inner body 140, the inside and outside of the display module 160 are preferably sealed.

The display module 160 is supported at an inner side by the upper inner body 140 and at an outer side by the outer visual body 214.

In the present embodiment, the display 160 is formed in a ring shape. Unlike the present embodiment, the display 160 may also be formed in an arc shape. The surface of the display 160 is formed of a material that reflects light or is coated with a material that reflects light.

Thus, in the case where the visual body 210 contains water, the water bound on the visual body 210 may be projected or reflected to the surface of the display 160. The same effect is exhibited in the display 160 in case that the water caught on the visual body 210 falls down.

Such an effect provides a visual stimulus to the user, and the user can intuitively recognize that humidification is being performed. The water droplet image projected on the display 160 has a functional effect of informing the user of the humidification state, in addition to a sensory effect of providing a refreshing feeling to the user.

The upper side of the display 160 is formed in an inclined manner. The display 160 is formed in a manner of being inclined toward the user side. Thus, it is formed to be high on the inner side and low on the outer side.

Next, the respective configurations of the air cleaning module 200 will be described.

The air wash module 200 provides humidification to the filtered air. The air purge module 200 may present a rain scene (rainview) in the humidification flow path 106. The air cleaning module 200 sprays water of the water tank 300 and circulates the sprayed water. The air cleaning module 200 converts water into small-sized droplets, and cleans the filtered air again by the scattered droplets. When the air is filtered by the scattered water droplet washing (washing), humidification and filtration are performed again.

The air purge module 200 includes: a humidification connection channel 105, a humidification channel 106, a discharge channel 107, and a water supply channel 109.

The air purge module 200 includes: a water tank 300, a watering unit 400, a humidifying medium 50, a visible body 210, a cap assembly 230, and a handle 180 (handle).

The handle 180 is combined with the viewing body 210, is rotated at the viewing body 210, and is received in the viewing body 210. By means of the handle 180, it is possible to simply lift and separate only the air cleaning module 200 from the air cleaning module 100.

The humidification connection channel 105 may be disposed outside the water tank 300, and guides air into the water tank 300. The humidification connection channel 105 may be disposed outside the visible light main body 210, and guides air into the visible light main body 210.

The humidification connection passage 105 may be disposed outside at least one of the water tank 300 and the visible light main body 210, and guides air into one of the water tank 300 and the visible light main body 210.

The discharge flow path 107 may be disposed between the cap assembly 230 and the visible light body 210. The discharge flow path 107 may be disposed in at least one of the head assembly 230 and the visual body 210.

In the present embodiment, the discharge flow path 107 is formed at the outer edge of the head unit 230, and the water supply flow path 109 is formed at the center of the inside of the head unit 230.

The humidification/purification apparatus of the present embodiment is connected to the air cleaning module 100, and the air cleaning module 200 is supplied with power through the air cleaning module 100.

Since the air cleaning module 200 is a structure separable from the air cleaning module 100, the air cleaning module 100 and the air cleaning module 200 are provided with separable power supply structures.

Since the air cleaning module 100 and the air cleaning module 200 are detachably assembled by the upper body 120, a connector 260 for supplying power to the air cleaning module 200 is provided at the upper body 120.

The top cover assembly 230 of the air cleaning module 200 is configured with an operating portion and a display that require power to be provided. A top connector 270(top connector) is provided in the air cleaning module 200 and detachably connected to the connector 260. The top connector 270 is disposed on the cap assembly 230.

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

The head assembly 230 has a water supply passage 109 formed therein and a discharge passage 107 formed with the visual body 210. The cap assembly 230 is detachably disposed with respect to the visual body 210. The header assembly 230 is configured with a top connector 270 that makes electrical connection with the connector 260.

When the cap assembly 230 is placed, the top connector 270 will be placed on the upper side of the connector 260. The header assembly 230 is supplied with power from the connector 260 through the top connector 270.

A water level display (not shown) for displaying the water level of the water tank 300 is disposed around the water supply channel 109. Thus, the user can confirm the level of the water in the invisible water tank 300 when supplying water. By disposing the water level display unit on the movement path of the water supply by the user in this manner, the water supply by the user can be prevented from being excessively performed, and the water in the water tank 300 can be prevented from overflowing.

The water level display part is disposed at the cap assembly 230. The separable power supply structure of the top connector 270 and the connector 260 can effectively constitute an upper water supply.

The water tank 300 is detachably placed on the upper body 120. The watering unit 400 is disposed within the sink 300 and rotates within the sink 300.

The water tank 300 includes: a water tank body 320 for storing water; an air purge inlet 31 formed in a side surface of the water tub body 320; a tank body extension 380 extending upward from the tank body 320 and coupled to the viewing body 210.

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

The water tub extension 380 is formed extending upward from the water tub 300. The tank body extension 380 forms the air purge inlet 31. The air purge inlet 31 is formed between the tank body extensions 380.

The air purge inlet 31 is formed on a side surface of the water tub body 320. The air cleaning inlet 31 is formed in all directions of 360 degrees with respect to the tub body 320. The air purge inlet 31 communicates with the humidification connection passage 105.

The water tank main body extension 380 guides water flowing down from the inner surface of the visible body 210 into the water tank 300. By directing the water falling from the visible body 210, the falling water noise can be minimized.

The tank body extension 380 is coupled to a lower end of the viewing body 210.

In the present embodiment, the air purge inlet 31 is formed by the structure of the sump body 320. Unlike the present embodiment, the air purge inlet 31 may be formed by disposing the tank body extension 380 on the visible body 210. Further, unlike the present embodiment, the air purge inlet 31 may be configured by disposing a part of the plurality of tank body extensions 380 in the tank 300 and disposing the remaining part of the plurality of tank body extensions 380 in the visible light body 210. Also, unlike the present embodiment, the air cleaning inlet 31 may be formed by a separate structure distinguished from the visible body 210 and the water tank 300. Further, unlike the present embodiment, the air cleaning inlet 31 may be formed by forming an open surface in the visible light body 210, and the air cleaning inlet 31 may be formed by forming an open surface in the water tank 300.

That is, the air purge inlet 31 may be disposed in at least one of the water tank 300 and the visible light main body 210. The air purge inlet 31 may be formed by a combination of the water tank 300 and the visual body 210. The air purge inlet 31 may be disposed between the water tank 300 and the visible body 210 after being disposed in a separate structure distinguished from the water tank 300 and the visible body 210. The air purge inlet 31 may be formed by combining the water tank 300 and the visible body 210.

The air purge inlet 31 is disposed at a side of the air purge module 200 and connected to the humidification flow path 106. The air purge inlet 31 may be in communication with or connected to the humidification connection flow path 105.

The watering unit 400 has a function of supplying water to the humidifying medium 50. The watering unit 400 has the function of visualizing the humidification process. The watering unit 400 has the function of presenting a rain scene inside the air wash module 200.

The watering unit 400 rotates the watering case 800 (watering) and sucks water inside the water tank, pumps up the sucked water to the upper side, and sprays the pumped water toward the radial outside. The watering unit 400 includes a watering case 800, and the watering case 800 sucks water into the inside thereof, and sprays the sucked water toward the radial outside after pumping up the water toward the upper side.

In this embodiment, the watering housing 800 is rotated for spraying water. Unlike the present embodiment, a nozzle may be used to spray water instead of the watering housing 800. Water may be sprayed from the nozzles to supply water to the humidification media 50 and may similarly present a rain scene. According to an embodiment, water may be sprayed from the nozzle and the nozzle may be rotated.

Water sprayed from the watering housing 800 wets the humidification media 50. The water sprayed from the watering housing 800 may be sprayed toward at least one of the visible body 210 or the humidifying medium 50.

The water sprayed toward the visible body 210 may present a rain scene. The water sprayed toward the humidification media 50 is used to humidify the filtered air. It may be implemented such that the water flowing down from the visible body 210 wets the humidification media 50 after the rain scene is presented by spraying the water toward the visible body 210.

In this embodiment, a plurality of injection ports having different heights are disposed in the watering case 800. The water discharged from one of the discharge ports forms droplets on the inner surface of the visual body 210 to show a rain scene, and the water discharged from the other discharge port wets the humidifying medium 50 for humidification.

The watering case 800 sprays water toward the inner side surface of the visible body 210, and the sprayed water flows down along the inner side surface of the visible body 210. A droplet formed in a form of a water droplet is formed on an inner side surface of the visual body 210, and a user can see the droplet through the visual body 210.

In particular, the water flowing down from the visual body 210 wets the humidifying medium 50 for humidification. The humidifying medium 50 may be wetted by water sprayed from the watering housing 800 and water that may fall from the visible body.

The viewing body 210 is combined with the water tub 300 and is positioned at an upper side of the water tub 300. At least a portion of the visible body 210 is formed of a material that can see through the inside.

A display module 160 may be disposed at an outer side of the visual body 210. The display module 160 may be combined with one of the visual body 210 or the upper body 120.

The display module 160 is disposed in a line of sight in which a rain scene is observable. In this embodiment, the display module 160 is disposed on the upper body 120.

When the air cleaning module 200 is placed, the outer side of the viewing body 210 is closely attached to the display module 160. At least a portion of the surface of the display module 160 may be formed of a material that reflects light or coated with a material that reflects light.

The liquid droplets formed in the visible body 210 will also be projected onto the surface of the display module 160. Thus, the user can observe the movement of the droplet at both the visible body 210 and the display module 160.

The water tank 300 is formed with an air-unblocked air purge inlet 31. The air purge inlet 31 is located between the connection flow path 103 and the humidification flow path 106. The air purge inlet 31 is an outlet of the connection flow path 103, and is an inlet of the humidification flow path 106.

The filtered air supplied from the air cleaning module 100 flows into the air cleaning module 200 through the air cleaning inflow port 31.

The humidification medium 50 includes: a water tank humidification medium 51 disposed at the inlet of the humidification flow path 106; and a discharge humidification medium 55 disposed at the outlet of the humidification flow path 106. The outlet of the humidification flow path 106 and the inlet of the discharge flow path 107 are connected to each other. Therefore, the discharge humidification medium 55 may be disposed in the discharge flow path 107.

Since the connection flow path 103, the humidification flow path 106, and the discharge flow path 107 are not formed by a structure such as a duct (duct), the boundaries thereof are not easily clearly distinguished. However, when the humidification flow path 106 for achieving 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 can be naturally defined.

The connection flow path 103 is defined as a portion between the blower fan case 150 and the water tank humidifying medium 51. The discharge flow path 107 is defined as a portion after the humidification medium 55 is discharged.

In the present embodiment, the tank humidification medium 51 is disposed at the air purge inlet 31 of the tank 300.

The water tank humidifying medium 51 may be located at least one of on the same plane as the air purge flow inlet 31, outside, or inside. Since the tank humidification medium 51 is wetted with water for humidification, it is preferably located inside the air purge inlet 31.

The water that flows down after wetting the sink wetting medium 51 is preferably stored in the sink 300. Preferably, the water tank is configured such that water flowing down after wetting the water tank humidifying medium 51 does not flow down to the outside of the water tank 300.

Thereby, the tank humidification media 51 humidifies the filtered air passing through the air purge inlet 31.

The filtered air is humidified using water naturally evaporated from the humidification media 50. The natural evaporation refers to a case where water is evaporated without applying additional heat. Natural evaporation will be promoted as the contact with air increases, the flow rate of air increases, and the pressure in the air decreases. The natural evaporation is also called natural vaporization.

The humidification media 50 promotes the natural evaporation of water. In the present embodiment, the humidification medium 50 is wetted with water, but is not immersed in the water tank 300.

Since the humidifying medium is disposed separately from the water stored in the water tank 300, the water tank humidifying medium 51 and the discharge humidifying medium 55 are not always wetted even if the water stored in the water tank 300 is present. That is, the water humidification medium 51 and the discharge humidification medium 55 are wetted only when operating in the humidification mode, and the water humidification medium 51 and the discharge humidification medium 55 can be kept dry when operating in the air purification mode.

The water tub humidifying medium 51 covers the air purge inlet 31, and air flows through the water tub humidifying medium 51 and into the water tub 300.

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

In the present embodiment, the discharge humidification medium 55 is disposed to cover the upper portion of the visible body 210. The discharge humidification medium 55 is placed on the visible body 210. Unlike the present embodiment, the discharge humidification medium 55 may be combined with the bottom surface of the cap assembly 230.

The discharge humidification medium 55 covers the discharge flow path 107, and the humidified air passes through the discharge humidification medium 55 and flows into the discharge flow path 107.

Fig. 6 is a perspective view of the air cleaning module shown in fig. 2 with the top cover assembly separated, and fig. 7 is a perspective view of the top cover assembly shown in fig. 6 and the humidification medium discharge case separated.

In this embodiment, the cap assembly 230 has a feature of being detachably disposed on the visual body 210. The head assembly 230 provides a water supply path 109 for supplying water in addition to the discharge path 107.

In this embodiment, the cap assembly 230 is located on the upper side of the discharging humidification medium 55. In this embodiment, a humidification discharge medium case 1400 having the humidification discharge medium 55 is disposed, and the top cover assembly 230 is disposed on the humidification discharge medium case 1400. The discharge humidification medium case 1400 is placed on the upper portion of the visual main body 210. The cap assembly 230 is placed on the upper part of the discharge humidification medium case 1400. The cap assembly 230 may be assembled with the discharge humidification media housing 1400 in an integrated manner. In this embodiment, the cap assembly 230 and the discharge humidification medium case 1400 are separately manufactured.

The top cover assembly 230 is supported by the visible body 210, and does not apply a load to the discharge humidification medium case 1400.

The discharge humidification medium case 1400 is provided with the discharge humidification medium 55 therein to cover the upper portion of the main body 210. The water supply flow path 109 is configured to pass through the discharge humidification medium case 1400. The discharge flow path 107 is configured to pass through the discharge humidification medium case 1400.

The cap assembly 230 includes: a head grid 232 for forming the discharge flow path 107 and the water supply flow path 109; an operating module 240 disposed at the top cover grill 232; a top connector 270 for supplying power or signals to the operating module 240.

The top cover grill 232 includes: a grill discharge port 231 for forming at least a part of the discharge flow path 107; and a grill water supply port 233 for forming at least a part of the water supply flow path 109. The grill discharge port 231 and the grill water supply port 233 are formed in an open state in the vertical direction. The grill water supply port 233 is disposed at the center of the inner side of the top cover grill 232, and the grill discharge port 231 is disposed at the outer side of the grill water supply port 233.

The top cover grill 232 is detachably disposed on the visual body 210. The top cover grill 232 is placed inside the visual body 210.

The operating module 240 is combined with the top cover grill 232. The operation module 240 may input an operation signal of a user. The operation module transmits water level information to a user. The operation block 240 is provided with a water supply passage 109. The operating module 240 is electrically connected to the top connector 270 and receives power supplied from the top connector 270.

The operation module 240(operation module) includes: an operation housing 250 combined with the top cover grill 232 and having at least a portion of the water supply flow path 109 formed therein; an input unit 245 disposed in the operation housing 250; a water level display portion 247 disposed at the operation housing 250; the input unit 245 and the water level display unit 247 are controlled by an operation control unit (not shown).

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

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

The operating module 240 further includes an upper water supply guide 236. The upper water supply guide 236 guides the water of the upper water supply to the operation water supply port 241. The upper water supply guide 236 is formed by forming a part of a face in the manipulation case 250 in an inclined manner.

When the upper water supply is performed, the user cannot see the water level inside the water tub 300, but the water level display 247 disposed around the operation water supply port 241 can immediately recognize the rising water level. Since the user can recognize the water level in the upper supply water through the water level display part 247, the upper supply water flow rate can be adjusted.

The water supplied from the upper part drops into the humidification flow path 106 through the discharge humidification medium case 1400. In particular, the water supplied from the upper portion does not directly drop to the surface of the sump 300, but drops toward the upper portion of the watering housing 800.

In case that the watering case 800 is rotated at the time of upper water supply, water of the upper water supply is scattered toward the upper portion of the watering case 800, thereby forming an additional rain scene.

That is, the water sprayed through the watering unit 400 may form a rain scene, and the water supplied through the upper portion may form a rain scene.

The watering housing 800 is a structure for spraying water stored in the water tank 300. The watering housing 800 is configured with a structure for effectively pumping up the water stored in the water trough 300.

The watering case 800 is rotated by the rotation force of the watering motor 42, and when rotated, sucks the water stored in the water tub 300 into the inside and pumps it up to the upper side. Water that is pumped into the watering case 800 is discharged through the injection port 410.

A water pumping unit is arranged on the watering shell 800. The pumping unit is used to pump (pumping) the water in the water tank 300 upward. There are various methods for pumping up the water in the water tank.

For example, the water may be sprayed after pumping up the water by the lift pump.

For example, the watering housing may be rotated, and the water may be pumped up by friction or interference with the water as the rotation is performed.

Referring to fig. 12 and 17, the present embodiment shows a structure in which water is pumped by rotation of the watering case 800. In the present embodiment, the pumping unit is a pumping groove 802(pumping groove) or a pumping rib 810(pumping rib) that pushes water to the upper side by friction or mutual interference with water.

A water pumping rib 810 as a water pumping unit is formed on the inner side surface of the watering case 800. The pumping ribs 810 and the pumping grooves 802 are used for improving pumping efficiency. The water-lifting rib 810 is formed at the inner side surface of the watering case 800 to protrude. The pumping rib 810 is formed to extend long in the up-down direction. The water-lifting ribs 810 are disposed radially with respect to the watering motor shaft 43 or the drive shaft 640. The plurality of water-lifting ribs 810 may be disposed on the inner side of the watering case 800. The plurality of water spouting ribs 810 may be disposed along the circumferential direction (circumferential direction) of the watering case 800.

The pumping channels 802 may be disposed between the pumping ribs 810. The pumping grooves 802 are formed to extend long in the up-down direction. The water lifting grooves 802 are radially disposed with respect to the watering motor 43 or the drive shaft 640. The watering channel 802 may be disposed in a plurality on an inner side of the watering housing 800. The plurality of water spouting grooves 802 may be disposed in a plurality along the circumferential direction (circumferential direction) of the watering case 800.

The lower end of the watering case 800 is spaced apart from the bottom surface of the water tub 300 by a prescribed interval to form suction intervals 801, H1. Water from the sink 300 is drawn into the interior of the watering housing 800 through the intake gap 801.

The water level H2 of the water tank 300 in which the watering case 800 can spray water is formed to be higher than the suction interval H1 and lower than the spray opening 410. The water level H2 contains a full water level.

When the water level H2 is lower than the suction interval H1, water cannot be pumped up because water is not sucked. When the water level H2 is higher than the injection port 410, the water pumped up to the injection port 410 cannot be injected.

The watering case 800 is formed in a state that the lower side thereof is opened. The watering housing 800 is cup-shaped. The watering case 800 is shaped to invert a cup. A housing space 805 is formed inside the watering housing 800.

The column 35(column) of the sink 300 is located inside the watering housing 800, and a transmission module 600 is disposed inside the column 35. The watering housing 800 is configured to encase the post 35. As shown in fig. 12, a plurality of bearings are vertically arranged inside the column 35, and the transmission shaft 640 may penetrate the plurality of bearings. As shown in fig. 12, a seal (sealant) may be disposed between the upper bearing and the upper end of the column 35. Further, a seal (sealant) may be disposed below the bearing disposed below.

The watering case 800 is formed such that its flat section becomes more expanded as it gets closer to the upper side. The pillar 35 is formed such that its flat section becomes smaller as it gets closer to the upper side. The watering housing 800 and the column 35 are shaped to effectively lift water. The volume of the housing space 805 becomes larger as it gets closer to the upper side.

When the watering case 800 rotates, the water sucked into the case will cling to the inner circumferential surface of the watering case 800 by the centrifugal force. The water pumping grooves 802 or the water pumping ribs 810 formed at the inner circumferential surface of the watering case 800 provide a rotational force to the water sucked inside.

The watering case 800 is formed with a jet port 410 for discharging the sucked water to the outside. In the present embodiment, the ejection port 410 is configured to eject water in a horizontal direction. The pumped water is discharged to the outside through the ejection port 410.

In the present embodiment, the water discharged from the discharge port 410 may be discharged toward the visible body 210.

The number of the injection ports 410 may be adjusted according to design conditions. In the present embodiment, the injection port 410 is provided in plurality in the watering case 800 in a manner having a height difference. The injection port disposed at the upper side of the watering case 800 is defined as a 2 nd injection port, and the injection port disposed at the middle of the watering case is defined as a 1 st injection port.

The water ejected from the 1 st ejection port is used for humidification. The water injected from the 2 nd injection port is used for humidification, watering, and rain.

The water sprayed from the 2 nd spray port may flow down and wet the water tank humidifying medium.

The water sprayed from the 2 nd spraying port may be scattered to form a rain scene after colliding with the visible body. The water sprayed from the 2 nd jet port is transformed into minute droplets after colliding with the visible body, and the droplets can be utilized in watering for cleaning the filtered air.

Water may be sprayed from the 1 st spray port while the watering housing 800 rotates at or above a first rotational speed. Water may be sprayed from the 2 nd injection port while the watering housing 800 rotates at or above a second rotational speed.

The second rotational speed is high compared to the first rotational speed.

Water is discharged from the 2 nd jet port only when the watering housing 800 is rotated at a high speed. May be configured to not dispense water through the 2 nd jet port at the speed at which the watering housing 800 normally rotates. The 1 st injection port spits water in all stages of the normal operation of the watering housing.

The 2 nd injection port may be provided in plurality. The number of the 1 st injection ports may be plural.

When the watering housing 800 is rotated at normal rotational speeds, the water that is pumped rises at least higher than the 1 st jet. When the watering case 800 rotates at a high speed, the water to be pumped rises above the level of the 2 nd injection port.

The 2 nd injection port may be provided in plurality along the circumferential direction of the watering case 800. The 1 st injection port may be provided in plurality along the circumferential direction of the watering case 800.

When the watering case 800 is not rotated, water cannot be discharged through the injection port 410. When the user operates the air cleaning module only in the cleaning mode (the mode in which the air cleaning module is operated and the air cleaning module is stopped), the watering unit 400 is not operated and only the air blowing unit 20 is operated. When the user operates only in the humidifying mode, the watering case 800 rotates and discharges water through the injection port 410. When the user drives the purge mode and the humidification mode at the same time, the water discharged from the discharge port 410 may be discharged toward the inner surface of the visible body 210.

As the watering case 800 rotates, the water spouted from the spouting port 410 hits the inner side surface of the visual body 210 and moves along the inner side surface of the visual body 210.

The user can visually confirm the condition of the sprayed water through the visible body 210. Such water injection is shown during operation in the humidification mode. The user can intuitively confirm that the operation in the humidification mode is in progress by the water injection.

When the visible body 210 is formed into droplets by the sprayed water, the droplets may fall downward.

In this embodiment, the watering housing 800 is constructed of three parts. Unlike the present embodiment, the watering housing 800 can be made of one or two pieces.

The lower end of the watering case 800 is disposed apart from the bottom surface of the water tank 300 by a predetermined interval.

The watering housing 800 comprises: a first watering housing 820, a second watering housing 840, a watering housing cover 860, and a watering transmission 880.

The watering housing 800 is assembled with a drive shaft 640, configured with structure for transmitting rotational force from the drive shaft 640. In this embodiment, the drive shaft 880 and housing cover 860 are assembled with the drive shaft 640 in the housing 800. The watering housing 800 is coupled to the drive shaft 640 at two locations and transmits rotational force from the two locations.

Unlike the present embodiment, the watering housing 800 may be coupled to the drive shaft 640 at one location and transmit rotational force from the coupled location.

Also, unlike the present embodiment, the watering housing 800 may transmit rotational force in other ways than a drive shaft. For example, the rotational force may be transmitted to the watering motor in a belt-and-pulley manner. For example, the rotational force may be transmitted to the watering motor in a gear engagement. For example, the rotational force may be transmitted to the watering motor in a chain driven manner. For example, the rotational force may be transmitted to the watering motor in a clutch fashion.

The drive shaft 640 is formed at upper and lower ends thereof with threads 643, respectively.

Upper end threads 643 are assembled with a water housing cover 860. The lower end threads are assembled with a second coupling 620 (coupler). A first coupler 610 combined with the second coupler 620 is provided at the upper body 120.

A watering motor 42 is provided in the upper body 120. The watering motor 42 provides a rotational force to the watering housing 800.

The coupling disposed at the air cleaning module 100 and associated with the watering motor 42 is defined as a first coupling 610. A coupler configured at the air cleaning module 200 and detachably combined with the first coupler 610 is defined as a second coupler 620.

One of the first coupling 610 or the second coupling 620 has a male shape and the other has a female shape. In the present embodiment, the first coupler 610 is fabricated in a male shape, and the second coupler 620 is fabricated in a female shape. In this embodiment, the first coupling 610 is detachably coupled in a state of being inserted into the second coupling 620. Unlike the present embodiment, the second coupling member 620 may be inserted into the first coupling member 610.

The watering motor 42 is disposed on the upper body 120. The watering motor 42 is provided on the upper side of the blower motor 22, separately from the blower motor 22. The water tank 300 is placed inside the upper body 120. The first and second couplers 610 and 620 are drivingly connected when the sink 300 is placed on the upper body 120. The watering motor shaft 43 of the watering motor 42 is disposed facing upward. A first coupling 610 is provided at the upper end of the watering motor shaft 43.

The various structures of the watering housing 800 are illustrated.

The upper and lower sides of the first watering case 820 are formed in an open state, respectively, and the inner side is formed with a water-lifting groove 802 and/or a water-lifting rib 810. The lower end of the first watering housing 820 is spaced apart from the bottom surface of the sump 300 by a predetermined interval, thereby forming a suction space 801.

The second watering case 840 is formed in an opened state at upper and lower sides thereof, respectively, and is assembled at an upper end of the first watering case 820. As shown in fig. 12, the upper end of the first watering housing 820 can be inserted into the lower end of the second watering housing 840.

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

The watering transmission 880 is connected to at least one of the first watering housing 820 or the second watering housing 840 to transmit a rotational force to the transmission module 600. In this embodiment, the watering transmission 880 is coupled to the first watering housing 820.

Unlike the present embodiment, the first and second watering housings 820 and 840 may be integrally formed. Also, unlike the present embodiment, the first watering case 820 and the watering case cover 860 may be integrally formed.

The first watering case 820 is formed wider in an upper side section than in a lower side section. The first watering case 820 is inclined in the up-down direction. The first watering housing 820 may be conical with a narrow cross-section at the lower side.

A water sprinkling rib 810 is formed inside the first watering case 820. The pumping rib 810 is formed in an up-and-down direction. The water-lifting ribs 810 are radially arranged with the watering motor shaft 43 as a center. The water pumping ribs 810 may be provided in plurality, and protrude toward the axial center of the watering case 800.

The lower end of the first watering housing 820 is spaced from the interior bottom surface of the tank 300 to form a suction space 801. The upper end of the first watering housing 820 is combined with the lower end of the second watering housing 840. As shown in fig. 12, the upper end of the first watering housing 820 and the lower end of the second watering housing 840 may radially overlap each other. The lower end of the second watering housing 840 may be located further outboard than the upper end of the first watering housing 820. The portion of the first and second watering housings 820,840 that overlap each other can be referred to as a border portion of the first and second watering housings 820,840. The boundary portion may include a first shutter 823, which will be described later. That is, the boundary portion may include a portion where the first and second watering housings 820, 840 overlap and a first baffle 823. The border portion may form a step between the first watering housing 820 and the second watering housing 840. The border portion may form a step on the inside of the watering housing 800. The boundary portion may be formed as a step on the outer surface of the watering case 800. The width of the portion of the watering housing 800 located on the upper side of the step may be greater than the width of the portion located on the lower side of the step. The width of the second watering housing 840 may be greater than the width of the first watering housing 820.

As shown in fig. 12, the step may be disposed above the pumping rib (810, lower rib). The step may be located at a position more upper than the upper end of the pumping rib 810.

As shown in fig. 12, the water film suppressing rib (870, rib portion of the upper rib) may be located on an upper side of the step, and the watering connecting portion (884, connecting portion) may extend from a position above the step to a position below the step. The step may be located at a height between upper and lower ends of the upper ribs 870, 884 including the water film inhibiting ribs 870 and the watering connection 884.

The first and second watering housings 820 and 840 may be assembled or disassembled. In this embodiment, the first and second watering housings 820 and 840 are assembled by screw bonding. A screw 822 is formed on the upper outer circumferential surface of the first water housing 820, and a screw 842 is formed on the lower inner circumferential surface of the second water housing 840.

The threads 822 formed on the first water housing 820 are defined as first threads 822 and the threads 842 formed on the second water housing 840 are defined as second threads 842.

A first barrier 823(barrier) for restricting the movement of the second watering housing 840 is formed at the lower side of the first screw 822. The first baffle 823 is formed along a circumferential direction of the first watering housing 820. The first shield 823 is formed in a band shape to protrude to the outside of the first watering case 820.

When the first and second watering housings 820, 840 are assembled, the first shield 823 abuts against the lower end of the second watering housing 840. The first shield 823 is formed to protrude outward more than the first thread 822.

A first packing 825(packing) is disposed between the first thread 822 and the first shield 823. The first gasket 825 serves to cut off water leakage between the first watering housing 820 and the second watering housing 840. The first gasket 825 is formed of an elastic material. The first gasket 825 is formed in a ring shape.

A spacer setting rib 824 is provided to fix the position of the first spacer 825. The spacer ribs 824 may be disposed on an extension of the first threads 822. The gasket-providing ribs 824 may be part of the first threads 822.

Thus, the first screw 822 may be formed in a plurality of discrete positions, one of which may be provided with a rib 824 for the gasket.

The first watering case 820 is provided with a 1 st injection port 411. In the present embodiment, two injection ports 411 are provided for the 1 st injection port 411. The two 1 st injection ports 411 are formed in mutually opposite directions.

The 1 st injection port 411 communicates the inside and outside of the first watering case 820. In this embodiment, the 1 st injection port 411 is formed to have an inner opening area wider than an outer opening area. The 1 st injection port 411 supplies water to the water tank humidifying medium 51 and wets the water tank humidifying medium 51. The 1 st injection port 411 may inject toward the water tank humidifying medium 51.

A watering wing 850 is formed on the outer circumferential surface of the second watering case 840. The hydrofoil 850 may provide a flow of humidified air. The watering wing 850 may pull ambient air in as the watering housing 800 rotates. The hydrofoil 850 has a function of a rain show unit for making liquid droplets fine, in addition to a function of flowing air.

The air in the humidification flow path 106 of the watering case 800 flows largely toward the discharge flow path 107 by the rotation of the blower fan 24, and the air around the watering fins 850 flows in the opposite direction. The watering wing 850 may partially form an air flow opposite to the air flow based on the blowing fan 24. Depending on the shape of the hydrofoil 850, air may be caused to flow in the same direction as the flow by the blower fan 24. Air around the perimeter of the watering housing 800 can also be funneled to the surface of the watering housing 800 by rotation of the watering wing 850.

The air flow by the watering wing 850 has the effect of causing water particles around the watering housing 800 to flow toward the water reservoir 300. The rotation of the watering wing 850 has the effect of creating an air volume and pulling water particles into the perimeter of the watering housing 800.

Thus, when water falls from the water supply passage 109 to the upper portion of the watering case 800, the flow of air by the watering fins 850 can collect the falling water toward the watering case 800.

In the case where water is supplied through the water supply flow path 109 while the watering case 800 rotates, the water may collide with the surface of the watering case 800 and be irregularly scattered. The air flow of the watering fin 850 causes water particles scattered during water supply to be collected on the surface side of the watering case 800.

The second watering housing 840 is formed with the 2 nd injection ports 412, 413. The 2 nd injection ports 412 and 413 inject water toward the visual body 210. In the present embodiment, two of the 2 nd injection ports 412 and 413 are arranged. One of the 2 nd injection ports is defined as a 2 nd-1 st injection port 412, and the other is defined as a 2 nd-2 nd injection port 413.

The 2 nd-1 st injection port 412 and the 2 nd-2 nd injection port 413 are arranged in different directions from each other. In the present embodiment, the 2 nd-1 st injection port 412 and the 2 nd-2 nd injection port 413 are arranged in opposite directions to each other. The 2 nd-1 st injection port 412 and the 2 nd-2 nd injection port 413 may be symmetrically arranged with reference to the drive shaft 640.

The 2 nd-1 st injection port 412 and the 2 nd-2 nd injection port 413 form an angle of 180 degrees as viewed in a plan view. The 2 nd-1 st injection ports 412 are disposed between the watering wings 850 when viewed from above. The 2 nd-2 nd injection ports 413 are also disposed between the watering wings 850.

The 2 nd-1 st injection port 412 and the 2 nd-2 nd injection port 413 are disposed at the same height as or higher than the watering wing 850 when viewed from the front. A part of trajectories S3, S4 of water injected from the 2 nd-1 st injection ports 412 and the 2 nd-2 nd injection ports 413 is located within a rotation radius of the watering wing 850.

Thus, when the watering case 800 rotates, a part of the water injected from the 2 nd-1 st injection port 412 and the 2 nd-2 nd injection port 413 collides with the watering wing 850 and is scattered.

In the present embodiment, the 2 nd-1 st injection port 412 and the 2 nd-2 nd injection port 413 form a predetermined step. The 2 nd-1 st injection port 412 and the 2 nd-2 nd injection port 413 are not arranged at the same height.

The position of the water colliding with the visual body 210 can be set differently by forming a level difference between the 2 nd-1 st injection port 412 and the 2 nd-2 nd injection port 413. Thus, when the watering housing 800 is rotated, the water injected from the 2-1 st injection port 412 and the water injected from the 2-2 nd injection port 413 pass through different paths from each other.

A trajectory S3 of the water ejected from the 2 nd ejection ports 412 and 413 and colliding with the inner side surface of the visual body 210 is defined as an ejection line.

An injection line formed by the 2 nd-1 st injection port 412 is defined as a first injection line L1, and an injection line formed by the 2 nd-2 nd injection port 413 is defined as a second injection line L2.

The spray lines formed at the visual body 210 do not mean only straight lines. The ejection line may form a curve according to an angle ejected from the ejection port.

Also, the thickness of the ejection line may be formed differently according to the diameter of the ejection port, respectively. That is, when the diameter of the ejection opening is large, the ejection line is formed thick, and when the diameter is small, the ejection line is formed thin.

In the present embodiment, the water injected from the 2 nd to 2 nd injection ports 413 passes through the water injected from the 2 nd to 1 st injection ports 412 at another height after a predetermined time after the water passes through the water with reference to a certain position of the visual body 210. That is, the two spray lines L1 and L2 are formed on the inner surface of the visual body 210, and the user can be more effectively informed of the spraying of the water through the visual presentation.

When water is discharged from the two 2 nd jetting ports arranged at a constant height, only one jetting line is formed. When the watering case 800 rotates at a high speed, the phase difference is formed very short even if the two 2 nd injection ports 412, 413 are located in opposite directions. In this case, the induced illusion is considered to flow from one jet line down into the water.

In addition, in the case where two jet lines are formed, since the position where water is collided is different, the sound generated due to the collision is also formed differently. That is, the sound occurring from the first ejection line and the sound occurring from the second ejection line will be formed differently. With such an audible difference, the user can audibly confirm that the watering housing 800 is rotating.

When only one jet line is formed, the same sound is continuously generated, and thus the user may not recognize the sound or may mistakenly recognize the sound as a simple noise.

The acoustic difference of the plurality of ejection lines has an effect of effectively transmitting the operation state to the visually impaired or the acoustically impaired. In addition, even in the absence of light, it is possible to easily confirm that the humidification/purification device is in operation.

A portion of at least one of the 2 nd injection ports 412, 413 that is covered may be covered by a watering housing cover 860. In this embodiment, the 2 nd-1 st injection port 412 is disposed in a completely opened state, and a part of the 2 nd-2 nd injection port 413 is overlapped with the watering case cover 860 and covered.

The watering housing cover 860 is positioned in front of the 2 nd-2 nd injection ports 413. The watering case cover 860 covers a portion of the upper side of the 2 nd-2 nd injection port 413.

In this embodiment, the watering housing cover 860 overlaps a portion of the 2 nd-2 nd injection ports 413 when combined with the second watering housing 840. In this embodiment, the watering housing cover 860 functions as a diffusion member. Unlike the present embodiment, an additional diffusion member may be configured to widely diffuse the water injected from the injection port.

For example, when injection molding the watering case, burrs (burr) may be intentionally formed through which the sprayed water is diffused.

The water injected from the 2 nd to 2 nd injection ports 413 interferes with the diffusion member so that the injection angle and width thereof are changed. The water interfering with the diffusion member is pulled toward the diffusion member side by the surface tension.

In the 2 nd-1 st ejection port 412 where the overlap with the diffusion member (overlap) is not formed, the diameter of the ejection port and the diameter of the discharged water are formed approximately. In the 2 nd-2 nd injection port 413 formed in superposition with the watering case cover 860, water is injected in a wider range than the diameter of the injection port.

The trajectory of the water injected from the 2 nd to 1 st injection ports 412 is defined as S3, and the trajectory of the water injected from the 2 nd to 2 nd injection ports 413 is defined as S4.

The 2 nd-2 nd injection port 413 is located at a slightly higher position than the 2-1 st injection port 412. A part of the 2 nd to 2 nd injection ports 413 is overlapped with a cover body plate 863(cover body) of the watering case cover 860 as a diffusion member.

Since the water injected through the 2 nd to 2 nd injection ports 413 interferes with the cover main body plate 863 and is injected, the injected water becomes more fine and is injected.

The droplets ejected from the 2 nd to 2 nd ejection ports 413 are formed smaller than the droplets ejected from the 2 nd to 1 st ejection ports 412. The trajectory S4 of the droplet ejected from the 2 nd-2 nd ejection port 413 is formed at a position on the upper side than the trajectory S3 of the droplet ejected from the 2 nd-1 st ejection port 412. The droplets ejected from the 2 nd to 2 nd ejection openings 413 are ejected wider than the droplets ejected from the 2 nd to 1 st ejection openings 412. Thereby, the ejection line L2 formed by the 2-2 ejection ports 413 being superimposed is formed wider than the ejection line L1 formed by the 2-1 ejection ports 412.

The watering fins 850 can not only flow air around the watering case 800 but also atomize water injected from the injection ports 410.

In the present embodiment, the water injected from the 2 nd injection ports 412 and 413 collides with the hydrofoil 850 to be miniaturized. The hydrofoil 850 may fine the water into a mist (mist) form.

The hydrofoil 850 does not refine all the water injected from the 2 nd injection ports 412 and 413. A part of the water injected from the 2 nd injection ports 412, 413 collides with the watering wing 850.

The water injected from the 2- injection ports 412 and 413 forms a predetermined trajectory S3, and the rotating watering wing 850 collides with the water on the trajectory S3. That is, some of the water injected from the 2 nd injection ports 412 and 413 collides with the watering fin 850 and is scattered, and the rest of the water collides with the inner surface of the visible body 210 without colliding with the watering fin 850.

The water colliding with the watering fins 850 is widely scattered in the humidification flow path 106, and is not scattered in a specific direction. For example, water flying from the watering wing 850 may wet the discharge humidification media 55. Water flying from the watering wing 850 may be caught on the visible body 210. Water flying from the watering wing 850 may float on the humidification flow path 106.

The water micronized by the watering fins 850 can effectively perform a rain scene. The fine droplets are coalesced into a small droplet form on the inner surface of the visible light main body 210.

A rain show unit may be disposed between the watering case 800 and the visible body 210 instead of the watering wing 850. The water injected from the injection ports 410 may collide with the rain show unit and be scattered. For example, a mesh screen (mesh) may be disposed between the visual body 210 and the watering case 800 as a rain show unit. The water sprayed from the watering housing 800 may be broken up into smaller droplets and then dispersed as it passes through the mesh screen.

In addition, the rain scene generated in the humidification flow path 106 may generate anions by a Lenard effect (Lenard effect).

The lenner effect is a phenomenon in which a large amount of anions are generated when water is pulverized by a large external force.

In the process of rain-scene performance, liquid drops scatter and collide with each other, and a large amount of anions are generated in the process.

When the water injected from the 1 st injection port 411 collides with the structure, anions are generated by the lenner effect.

When the water injected from the 2 nd injection ports 412 and 413 collides with the visible light main body 210, anions are generated by the lenner effect.

When the water injected from the 2 nd injection ports 412 and 413 collides with the watering fins 850, anions are generated by the lenner effect.

Further, when the liquid droplets scattered from the watering case cover 860 collide with various structures during the upper water supply, anions are generated by the lenner effect.

As described above, in the present embodiment, the droplets of various sizes for producing a rain scene have an effect of generating anions in the production process. The generated anions are discharged into the chamber through the discharge passage 107.

Referring to fig. 12 and 14, a water film suppressing rib 870 for suppressing a rotational flow of a water film is formed inside the second watering case 840. The water film rotating flow refers to a flow rotating along the inner side surface of the watering case 800. The water film suppressing rib 870 may be disposed above the water pumping rib 810. Hereinafter, the water film inhibiting ribs 870 and the watering connecting portion 884 are also referred to as upper ribs 870 and 884. The pumping rib 810 is also referred to as a lower rib 810. The water film suppressing ribs 870 and 884 and the pumping rib 810 may be divided into first and second ribs. The watering connection 884 may extend from the water film inhibiting rib 870 toward the center of rotation of the watering housing 800. The watering connection 884 may extend to a position lower than the upper end of the water-lifting fin 810.

Also, as shown in fig. 12, the upper ribs 870, 884 and the lower ribs 810 may be disposed at different positions from each other in the circumferential direction of the watering case 800.

The water lifting ribs 810 of the first watering case 820 are used for forming the water film rotary flow, and the water film inhibiting ribs 870 are used for inhibiting the water film rotary flow.

In the first watering case 820, since water needs to be pumped up to raise water to the second watering case 840, a water film swirling flow is actively generated, and the more easily the water raised to the second watering case 840 is injected through the 2 nd injection ports 412, 413 without forming the water film swirling flow.

In the case where a high-speed water film is formed inside the second watering case 840 to rotate and flow, water flows along the inside, not being discharged through the 2 nd injection port.

Also, the greater the amount of water retained in the second watering housing 840, the greater the shock created in the watering housing 800 becomes. The water pumped up to the second watering housing 840 needs to be rapidly injected through the 2 nd injection ports 412, 413 to minimize eccentricity of the watering housing 800 and to minimize vibration corresponding thereto.

The water film restraint ribs 870 function to minimize rotational flow of the water film, thereby minimizing eccentricity and vibration of the watering case 800.

The water film suppressing rib 870 is convexly formed at an inner side surface of the second watering case 840. In the present embodiment, the water film suppressing rib 870 is convexly formed toward the transmission shaft 640. The water film suppressing rib 870 is formed in a direction intersecting with the rotational flow of the water film.

The water film rotating flow flows spirally or circularly along the inner side surface of the second watering housing 840, and the water film inhibiting ribs 870 are preferably formed in the up-down direction.

In the present embodiment, the water film suppressing rib 870 is formed along the vertical direction. The water film inhibitor 870 may be formed in plural. In this embodiment, three water film suppressing ribs 870 are provided. The plurality of water film inhibiting ribs 870 are disposed at equal intervals with respect to the inner circumferential surface of the watering case. As shown in fig. 12, 14, and 15, the intervals between the plurality of water film suppressing ribs 870 may be greater than the intervals between the plurality of pumping ribs 810. The number of the plurality of water film inhibiting ribs 870 may be less than the number of the plurality of water pumping ribs 810.

In this embodiment, the water film suppressing rib 870 has a protruding length of 5 mm. The length of the protrusion of the water film suppressing rib 870 is related to the thickness of the water film swirling flow, and may be variously changed according to the embodiment.

In this embodiment, the water film inhibiting ribs 870 are formed in such a manner as to be connected to the watering transmission portion 880. Unlike the present embodiment, the water film restraining bar 870 and the watering transmission 880 may be configured in a separate manner.

In this embodiment, the water film suppressing ribs 870 are connected to the watering transmission 880, so that the mold can be simplified.

The watering transmission 880 is a structure for transmitting the rotational force of the transmission shaft 640 to the watering housing 800.

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

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

The watering transmission 880 includes: a hub setting portion 882 located at the axial center of the watering case 800; a water connection 884 connecting the hub arrangement 882 to the water housing 800. In this embodiment, the hub arrangement 882, the water connection 884, and the second water housing 840 are injection molded as a single piece.

The watering connection 884 is made in the form of a tendon. The watering connection portions 884 are radially arranged with respect to the axis center, and are formed in plural numbers. As shown in fig. 12, the watering connection 884 may be angled downwardly along the radially inner side of the watering housing 800. The upper rim (or upper edge) of the watering connection 884 may be angled upward along the radially outer side of the watering housing 800. The lower rim (or lower edge) of the watering connection 884 may be angled upward along the radially outer side of the watering housing 800.

In this embodiment, the watering connecting portion 884 and the water film inhibiting ribs 870 are integrally formed. The watering connecting portion 884 and the water film restraining rib 870 are formed in a connected manner. The watering connection 884 and the water film inhibiting tendon 870 may also be referred to as upper tendons 870, 884. The watering connecting portion 884 may be referred to as a connecting portion 884, and the water film inhibiting ribs 870 may be referred to as rib portions 870.

The transmission shaft 640 is disposed through the bushing arrangement 882.

The lower side of the liner installation portion 882 is formed in an open state. A bush 90(bushing) is inserted through the lower side of the bush disposing portion 882 in an open state.

The liner setting portion 882 and the liner 90 can be separated in the up-down direction. The bush-setting portion 882 and the bush 90 are mutually locked in the rotational direction.

Therefore, a bush retaining portion 93 is formed on one of the bush positioning portion 882 and the bush 90, and a bush retaining groove 883 is formed on the other. In the present embodiment, the bush 90 is formed with the bush locking portion 93, and the bush setting portion 882 is formed with the bush locking groove 883.

The bushing catching groove 883 is formed at an inner side surface of the bushing seating part 882, which has a concave shape. The bushing retaining portion 93 is formed on the outer side surface of the bushing 90 in a convex shape.

The bushing locking portion 93 is inserted into the bushing locking groove 883 and is clamped.

Unlike the present embodiment, the bush setting part 882 and the bush 90 may be manufactured in an integrated manner. Since the bushing 90 is made of a metal material, the bushing 90 can be integrally formed by injection molding the second watering case material after being disposed in the mold when the second watering case 840 is manufactured.

The bushing 90 is coupled with the drive shaft 640 of the drive module 600.

The bushing 90 is coupled with the driving shaft 640 to transmit a rotational force. The bushing 90 is preferably formed of a metal material. In the case of a material other than a hard metal material, abrasion may occur, which becomes a cause of vibration.

The bushing 90 is formed with a bushing shaft center hole penetrating in the vertical direction. The drive shaft 640 is inserted into the bushing shaft hole.

The bushing 90 serves to reduce vibration as the watering housing 800 is rotated. The bushing 90 is located on the drive shaft 640. In this embodiment, the liner 90 is located at the center of gravity of the watering housing 800. Because the bushing 90 is located at the center of gravity of the watering housing 800, the vibration of the watering housing 800 can be substantially reduced when the bushing is rotated. As shown in fig. 12, the bushing 90 may be disposed on an upper side of the cylinder 35. The bushings 90 may be disposed at a height corresponding to the step between the first and second watering housings. The lower end of the bush 90 may be disposed at a position lower than the step. The bushing 90 may be located at a height corresponding to an upper side of the water lifting rib 810. That is, the liner 90 may overlap with an upper side portion of the water lifting rib 810 in a radial direction of the watering case 800.

The bushing 90 and the drive shaft 640 are assembled in a clamping engagement. The bushing 90 is supported by the drive shaft 640.

To support the bushing 90, the transmission shaft 640 is formed with a shaft support end 642. The diameter of the upper side is small and the diameter of the lower side is large, based on the shaft support end 642.

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

To minimize wear, the shaft support end 642 may be formed as a cone, cavity, or curved shape. In the case where the shaft supporting end 642 is formed at a right angle, abrasion may occur during an assembling process or an action.

In the case where the shaft supporting end 642 is worn, it becomes a cause of the movement of the bushing 90 and causes vibration. Also, in the event that the shaft support end 642 is worn, the bushing 90 will likely tilt or move, thereby causing poor alignment with the drive shaft 640. Also, in the case where a misalignment of the bush 90 and the drive shaft 640 occurs, eccentricity occurs when rotation is performed, and thus vibration is caused.

The watering housing cover 860 is combined with the upper side of the second watering housing 840 for closing the upper side of the second watering housing 840. 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 transmission module 600. Unlike the present embodiment, the watering housing cover 860 may be formed in a state of being separated from the transmission module 600.

With the combination of the watering housing cover 860 and the drive shaft 640, eccentricity and vibration of the watering housing 800 can be more effectively reduced.

The watering case cover 860 comprises: a cap body 862 covering an upper opening portion of the second watering case 840; a cover body plate 863 formed to extend downward from the cover body 862 to cover an upper end of the second watering case 840; a spacer setting rib 864 formed at a lower side of the cover main body 862 and spaced apart from the cover main body plate 863 by a predetermined interval; a shaft fixing portion 866 fixed to the transmission shaft 640; and a rib 868 for connecting the shaft fixing portion 866 and the spacer-providing rib 864.

The cap body 862 is formed in a circular shape as viewed in plan. The cap body 862 has a diameter formed larger than the diameter of the second watering housing 840.

Unlike the present embodiment, the planar shape of the cap body 862 may not be circular. Also, the planar shape of the watering case 800 is not limited to a specific shape.

The cover body plate 863 forms a periphery of the cover body 862. The cap body plate 863 is formed in a ring shape and is integrally formed with the cap body 862. The cover body plate 863 is formed at an outer side surface with a plurality of protrusions 861, the protrusions 861 being formed over a range of 360 degrees in a circumferential direction. The protrusions 861 provide a gripping feel to the user when the watering housing cover 860 is detached.

The projection 861 can effectively scatter water falling during the upper water supply. Water falling through the upper water supply drops to the watering housing cover 860 and flows toward the cover body panel 863 under the rotating action of the watering housing 800. Then, after being separated in the form of water drops from the protrusions 861, it is thrown toward the inner side of the visual body 210. The projection 861 can effectively scatter water supplied from the upper portion.

The gasket providing ribs 864 are located inside the cover body plate 863 to be spaced apart from the cover body plate 863 by a predetermined distance. A second gasket 865 is provided between the cover main body plate 863 and the gasket setting rib 864.

The space between watering housing cover 860 and second watering housing 840 can be closed by said second gasket 865. Since the water leakage from the housing space 805 is cut off by the first and second gaskets 825 and 865, the pressure of the water discharged through the discharge port 410 can be kept constant.

In the case where water leakage occurs between the first and second watering cases 820 and 840 or between the second watering case 840 and the watering case cover 860, it is difficult to keep the pressure of water discharged from the injection port 410 constant.

That is, in the case where water leakage occurs in the watering case 800, even if the watering case 800 is rotated, there is a possibility that water is not sprayed at the spray port 410.

The cap body plate 863 and the second watering housing 840 may be combined in a screw manner. In this embodiment, the water housing cover 860 and secondary water housing 840 are assembled with an interference fit.

The shaft fixing portion 866 is assembled with the propeller shaft 640 to transmit a rotational force from the propeller shaft 640.

The shaft fixing portion 866 and the driving shaft 640 may be combined in a screw manner. For this purpose, a screw thread 643 for screw coupling with the water housing cover 860 is formed on an upper end outer circumferential surface of the drive shaft 640.

A screw thread for assembling with the propeller shaft 640 may be formed at the shaft fixing portion 866. In this embodiment, a shaft fixing member 867 is disposed on the shaft fixing portion 866, and the shaft fixing member 867 is integrated with the shaft fixing portion 866 by a double injection molding method. In the present embodiment, a nut is used as the shaft fixing member 867.

Unlike the watering case cover 860, the shaft fixing member 867 is made of a metal material. Since the transmission shaft 640 is formed of a metal material, a portion to be screw-coupled with the transmission shaft 640 is also formed of a metal material so as to prevent abrasion or damage from occurring when coupling is performed. In the case where the watering case cover 860 is formed entirely of a metal material, or the shaft fixing portion 866 is formed of a metal material, it is preferable to form a screw thread on the shaft fixing portion 866 itself.

The watering housing cover 860 is formed 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.

Thereby, at least a part of the water supplied to the water supply flow path 109 can drop toward the watering case cover 860. With the rotation of the watering case 800, the water dropping toward the watering case cover 860 is sprayed radially outward on the surface of the watering case cover 860.

The rotating watering case cover 860 sprays the supplied water in the rotating direction, and an effect as if the water dropped from an umbrella can be exhibited. In particular, water droplets may be peeled off at a plurality of protrusions 861 arranged along the circumferential direction of the watering case cover 860.

Water sprayed from the watering case cover 860 in a rotating direction collides with the inner side surface of the visual body 210 and can perform a rain scene.

The rain scene is a state in which the liquid droplets formed on the inner surface of the visible body 210 appear as if raindrops fall.

Referring to fig. 12, in the present embodiment, the pumping rib 810 is designed in a form capable of efficiently pumping water of the water tub 300. In the present embodiment, the pumping rib 810 is located at a lower position than the injection port 410. In particular, the pumping rib 810 is formed lower than the 1 st injection port 411.

The water pumping ribs 810 convert the horizontal rotational force into the vertical direction with respect to water. In the case where the pumping rib 810 is formed, pumping can be more effectively performed in a vertical direction.

In this embodiment, the pumping ribs 810 are formed at an inner side surface of the watering case 800 and protrude toward the inside. The pumping rib 810 is formed to extend long in the up-down direction. Unlike the present embodiment, the water pumping ribs 810 may be formed in a zigzag shape. In this embodiment, since the first watering case 820 is manufactured by injection molding, the water-lifting ribs 810 are arranged in the vertical direction, so that the mold can be easily pulled out.

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

In the present embodiment, the case in which the humidification medium discharge 55 is provided in the humidification medium 50 is defined as a humidification medium discharge case 1400.

In the present embodiment, the discharge humidification medium case 1400 is disposed in the discharge flow path 107. The discharge humidification media housing 1400 may be disposed in the cap assembly 230. The discharge humidification media housing 1400 may be integrally formed with the cap assembly 230.

In this embodiment, the discharge humidification medium case 1400 is made of a separate structure from the top cover assembly 230. The discharge humidification medium case 1400 is disposed below the top cover assembly 230. The discharge humidification medium case 1400 may be detachably assembled to the head assembly 230. In this embodiment, the discharge humidification medium case 1400 is placed on the visual main body 210.

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

The discharge humidification medium case 1400 allows air to pass through to the outside and water to pass through to the inside. Air passes from the lower side to the upper side, and water passes from the upper side to the lower side.

The discharge humidification medium case 1400 has a discharge flow path 107 for passing air on the outside and a water supply flow path 109 for passing water on the inside.

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

The upper and lower cases 1410 and 1420 are formed with a plurality of gaps.

The upper case 1410 is formed in a circular ring shape as a whole.

The upper case 1410 includes: an upper inner frame 1412(upper inner frame) disposed at the center; an upper housing opening 1415 formed in the center of the upper inner frame 1412 to provide the water supply passage 109; an upper outer frame 1414 which is disposed apart from the upper inner frame 1412 and is disposed on the outer periphery; an upper sieve frame 1416 connects the upper inner frame 1412 and the upper outer frame 1414.

The lower case 1420 is formed in a circular ring shape as a whole.

The lower case 1420 includes: a lower inner frame 1422 disposed at the center; a lower case opening 1425 formed in the center of the lower inner frame 1422 and providing the water supply passage 109; a lower outer frame 1424 disposed outside the lower inner frame 1422; and a lower screen frame 1426 connecting the lower inner frame 1422 and the lower outer frame 1424.

The upper and lower housings 1410 and 1420 correspond in shape to each other.

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

The upper and lower cases 1410 and 1420 are assembled with each other. In this embodiment, the upper and lower cases 1410 and 1420 are coupled by clamping. For this purpose, the upper case 1410 or the lower case 1420 has clamp projections 1411, 1413 formed on one side and clamp grooves 1421, 1423 formed on the other side.

In the present embodiment, clamping protrusions 1411, 1413 are formed at the upper case 1410, and clamping grooves 1421, 1423 are formed at the lower case 1420. The clamping protrusions are formed on the upper inner frame body 1412 and the upper outer frame body 1414, respectively. The clamping grooves are formed in the lower inner frame body 1422 and the lower outer frame body 1424, respectively.

The water supply cap 1430 may be combined with at least one of the upper case 1410 or the lower case 1420. In this embodiment, the water supply cap 1430 is detachably clamped to the lower housing 1420. Unlike the present embodiment, the water supply cap 1430 may be detachably provided to the upper case 1410.

In order that the water supply cap 1430 and the lower case 1420 are detachably coupled, a coupling protrusion 1437 and a coupling groove 1427 are formed.

A coupling protrusion 1437 is formed at one of the water supply cap 1430 and the lower case 1420, and a coupling groove 1427 is formed at the other. In the present embodiment, a coupling protrusion 1437 is formed at the water supply cap 1430, and a coupling groove 1427 is formed at the lower case 1420.

The combining protrusion 1437 and the combining groove 1427 form a clamping combination in a horizontal direction.

The coupling protrusion 1437 is protrusively formed toward a radial outside of the water supply cap 1430. The coupling groove 1427 is formed to be opened toward the center of the lower case 1420.

The coupling protrusions 1437 are three and arranged at equal intervals, and the coupling grooves 1427 are formed corresponding thereto. In addition, a coupling protrusion locking portion 1428 that is locked to the coupling protrusion 1437 is formed in the coupling groove 1427. The engagement projection detents 1428 provide mutual detents with respect to the radial direction of the lower housing 1420.

The coupling protrusion catching portion 1428 may be formed to protrude toward the radial inside of the lower case 1420.

The user can rotate in a clockwise direction after inserting the water supply cap 1430 into the lower case opening 1425, thereby coupling the coupling protrusion 1437 with the coupling groove 1427. In the process that the combining protrusion 1437 is combined with the combining groove 1427, the combining protrusion 1437 goes over the combining protrusion catching portion 1428 and forms a "click" operation sound and operation feeling.

In addition, a water supply structure 1440 is formed in the discharge humidification medium case 1400, and temporarily stores the supplied water and discharges the stored water to the lower side.

The water supply structure 1440 includes: a reservoir 1441(reservoir) provided in the water supply flow path 109 and temporarily storing water; a water supply port 1445 for discharging water from the reservoir 1441 to the sink 300.

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

The water reservoir 1441 may be formed in at least one of the upper housing 1410, the lower housing 1420, and the water supply cap 1430 disposed in the water supply passage 109. The water reservoir 1441 may be formed by being coupled to at least one of the upper housing 1410, the lower housing 1420, and the water supply cap 1430 disposed in the water supply passage 109.

In the present embodiment, the water reservoir 1441 is formed by a combination of the lower housing 1420 and the water supply cap 1430.

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

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

The reservoir base 1442 is configured in a horizontal manner, with the discharge humidification media 55 positioned on the upper side of the reservoir base 1442. The reservoir base 1442 is connected to the lower screen frame 1426.

The reservoir wall 1444 is convexly formed at an upper side of the reservoir base 1442. The lower housing opening 1425 is disposed inside the reservoir wall 1444, and the humidifying medium 55 is disposed outside. The water supply cap 1430 is located inside the reservoir wall 1444.

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

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

The water supply port 1445 is formed in a slit (slit) shape. The water supply port 1445 is formed in an open state in the up-down direction. The water supply port 1445 is formed in a circular arc shape in a plan view. The water supply port 1445 is formed along an inner boundary of the reservoir wall 1444.

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

The water supply port 1445 is formed to have a wider upper cross section and a narrower lower cross section when viewed in a vertical cross section. The water supply port 1445 has a funnel shape with a sharp lower portion when viewed in a vertical direction.

The water supply port 1445 may cut off the flow of air by such a sectional shape, and allow water to be discharged downward.

When the humidification/purification device is operated, air flows from the humidification flow path 106 to the discharge flow path 107, and a part of the air can be 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. This is because the self weight of the water stored in the water reservoir 1441 is greater than the pressure of the air.

In case that the section of the water supply port 1445 is formed widely, air may be discharged, and in the process, a problem of water stored in the water reservoir 1441 splashing upward occurs.

The water supply structure 1440 of the present embodiment can prevent water in the reservoir 1441 from splashing in the direction opposite to the water supply even when the humidification/purification device is being operated.

The air can be prevented from being spit out from the water supply port 1445 by adjusting the capacity of the water reservoir 1441. For example, it can be made that the pressure caused by the self-weight of the water stored in the reservoir 1441 is more than the wind pressure that can be discharged through the water supply port 1445.

At the same time, when the water supply port 1445 formed in a slit shape is formed to have a narrow width, air can be made to flow to the discharge humidification medium 55 by the resistance. When the gap of the discharging humidification medium 55 is larger than the cross-sectional area of the water supply port 1445, air flows toward the discharging humidification medium 55 having a small resistance. On the other hand, in the case where water is stored in the reservoir 1441, the water is discharged through the water supply port 1445 by its own weight.

As described above, air can be prevented from being discharged through the water supply port 1445 by various methods.

When the user supplies water above the water supply cap 1430, the supplied water is temporarily stored to the water reservoir 1441. The water stored in the reservoir 1441 is drained to the lower side through the water supply port 1445. The water of the water reservoir 1441 may be discharged through a combining groove 1427 formed at the water reservoir base 1442. The water of the water reservoir 1441 may be discharged through the lower housing opening part 1425.

In the event that more water is supplied than the capacity of the reservoir 1441, the water may spill outward over the reservoir walls 1444. Even if the water overflows to the outside of the reservoir wall 1444, the supplied water drops or falls toward the visual body 210. The water falling along the visible body 210 will also be guided to the inside of the water tank 300.

The humidification/purification device of the present embodiment has an advantage that water can be supplied to the water tank 300 regardless of the operation state thereof.

In the present embodiment, the discharge humidification medium case 1400 is disposed below the head cover assembly 230, but unlike the present embodiment, the humidification/purification device may be configured without providing the head cover assembly 230. That is, the discharge humidification medium case 1400 having the water supply cap 1430 disposed therein is exposed to the outside, and water is poured into the water supply cap 1430, thereby supplying water to the upper portion.

Hereinafter, the flow of water when the upper water supply is performed will be described in more detail.

The water supplied from the upper portion drops downward through the cap assembly 230.

In this embodiment, water falling from the cap assembly 230 does not fall directly to the surface of the sink 300, but rather at least a portion thereof falls toward the upper portion of the watering housing 800.

In the case where the humidifying/purifying device is operated in the humidifying mode (the watering case is rotated), water supplied from the upper portion is scattered after falling down on the watering case 800, and a rain scene is formed in the process.

When the humidification/purification device is stopped or when the humidification/purification device is operated in the purification mode (when the watering case is stopped), water supplied from the upper portion flows along the watering case 800 to the water tank 300.

That is, regardless of the operation state of the humidification and purification device, the water supplied from the upper portion can be prevented from directly dropping on the water surface of the water tank 300, and thus the falling water noise can be minimized.

In terms of water characteristics, water flowing along the bottom surface of the discharge humidification medium housing 1400 in the water supplied from the upper portion may directly fall to the water surface. However, this is only a small amount of water, and it constitutes only a part of the total noise. In particular, the water coalesced on the bottom surface of the discharged humidification medium case 1400 may be absorbed by the discharged humidification medium 55 by the air flow in the humidification flow path 106 after the water drops to some extent.

The upper water supply water drops down the watering housing cover 860 of the watering housing 800.

To enable water from the upper water supply to fall to the watering housing cover 860, the watering housing cover 860 is formed with a diameter larger than that of the water supply port 1445.

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

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

When the watering case 800 is rotated, water supplied from the upper portion is scattered radially outward by the watering case cover 860. In order to effectively scatter water of the upper water supply, a protrusion 861 is formed at the watering case cover 860. The protrusions 861 are provided in plurality along the edge of the watering case cover 860. The projection 861 projects radially outward of the watering housing cover 860.

As the watering housing 800 rotates, the water from the upper supply is separated into droplets at the protrusion 861.

The liquid droplets separated from the protrusions 861 collide with the inner side surface of the visual body 210. To this end, the watering housing cover 860 is preferably disposed in a horizontal line with at least a portion of the visible body 210. Considering that the scattered liquid drops fall down by gravity, it is preferably located at the middle height of the viewing body 210.

The projection 861 is located at a higher position than the 2 nd ejection ports 412, 413.

A rain scene is performed by the liquid droplets flying from the projection 861. Through the rain scene formed when supplying water to the upper portion, the user can confirm that water supply is normally performed. In addition to confirmation of the upper water supply by the effect of the visual means such as a rain scene, the upper water supply may be confirmed by the sound generated by the scattered liquid droplets colliding with the visual body 210.

There is a difference between the sound of the rain scene occurring when the water is supplied from the upper portion and the sound through the ejection port 410. The sound of the rain scene occurring when the water is supplied from the upper portion is formed more largely than the sound of the rain scene occurring by the water pumping and is formed in an irregular manner.

In addition, when water is supplied to the upper portion, various sizes of droplets are scattered on the watering case cover 860.

In the case of a large droplet, the droplet flies from the projection 861 to the inside of the visible body 210 by its own weight. In the case of a large droplet, a relatively constant trajectory S1 is formed by its own weight.

The trajectory S1 is different from the trajectory S3 of the water ejected from the ejection openings 410.

The trajectory S3 of the water ejected from the 2 nd ejection ports 412 and 413 is different from the trajectory S1 of the water splashed from the projection 861. The locus S1 is formed higher than the locus S3.

In the case of small droplets, the droplets are more influenced by the air flow formed in the humidification flow path 106 than by their own weight.

Therefore, in the case of small droplets, they can float within the humidification flow path 106. It will take an irregular track due to the influence of both the wind pressure of the blowing fan 24 and the gravity.

In the case of smaller droplets, a phenomenon is created in which the wetting flow path 106 is pulled near the watering case 800 while floating.

The wings 850 of the watering housing 800 pull the floating droplets. The floating or flying droplets are pulled toward the surface of the watering case 800 by the air flow of the watering wing 850.

The watering wing 850 may form a water film S2 by pulling droplets of liquid flying from the watering housing cover 860. When the upper water supply is performed, the water film generated around the watering case 800 may take different shapes according to the amount of water supplied from the upper portion.

However, the water film has features that are symmetrically formed with respect to the watering housing 800.

Fig. 30 is a schematic view showing a flow of water inside the air cleaning module at the time of upper water supply, fig. 31 is a schematic view showing a trajectory of water sprayed through the 2-1 th spray ports, fig. 32 is a schematic view showing a trajectory of water sprayed through the 2-2 nd spray ports, and fig. 33 is a schematic view plotting a spray line.

The rain scene performed in the air cleaning module 200 will be described in more detail.

A rain scene is an effect as if it were raining outside a window. The rain scenery is the effect of rain. In the present embodiment, an effect as if it were raining or an effect of becoming rainwater is performed inside the visible body 210.

When the rain scene is performed, liquid drops with various sizes are formed. The air flows of the watering wing 850, the 1 st injection port 411, the 2 nd-1 st injection port 412, the 2 nd-2 nd injection port 413, the watering case cover 860, the protrusion 861, and the blower fan 24 are rain show units for generating the liquid drops.

The 1 st injection port 411, the 2 nd-1 st injection port 412 and the 2 nd-2 nd injection port 413 are used when water for pumping is injected in the watering unit 400. A rain scene is performed by the water injected from the 1 st injection port 411, the 2 nd-1 injection port 412, the 2 nd-2 injection port 413.

The watering case cover 860 or the projection 861 performs a rain scene by scattering water dropped when water is supplied from the upper portion.

The ejected or scattered droplets can be pulverized into smaller sizes based on the wind pressure or the wind volume of the blower fan 24. As the air flowing by the blower unit 20 passes through the water tank humidification medium 51, the droplets can be further miniaturized.

The air flowing through the air blowing unit 20 can make the air falling from the humidification flow path 106 fine. Since the air by the air blowing unit 20 moves in the direction opposite to the gravity, the air collides with the air dropped by its own weight and the dropped liquid droplets, and the air is made finer.

The liquid droplets generated by the rain show unit described above may flow or float in the humidification flow path 106. The liquid droplets in the humidification flow path 106 can humidify the flowing air, and can be formed in the form of water droplets on the inner surface of the visible light main body 210.

The water drops formed on the inner surface of the visual body 210 may move obliquely along the inner surface of the visual body 210.

The visible body 210 is formed in an inclined manner toward the water tank 300. The visual body 210 is formed to be wider at an upper side thereof and narrower at a lower side thereof. This can extend the residence time of the liquid droplets flowing along the visible body 210, thereby extending the rain show time. The inclination of the visible body 210 can suppress the liquid droplets formed from the liquid droplets from flowing downward. The droplet may maintain a state of being caught on the visual body 210 by the surface tension of the droplet. Further, the air flow of the air blowing unit 20 can suppress the liquid droplets from flowing down.

A waterproof coating layer may be formed on an inner surface of the viewing body 210. In the case where the waterproof coating layer is formed, it is possible to prevent the liquid droplets from spreading widely and to form a pattern of the liquid droplets more roundly.

In the case where the visual body 210 has water, the water tied on the visual body 210 is projected or reflected to the surface of the display 160. The same effect is exhibited in the display 160 in case that the water tied on the visual body 210 falls down.

In the visible body 210, the actual liquid droplets move from the upper side to the lower side, and from the outer side to the inner side along the inclination. The droplets reflected on the surface of the display 160 move from the lower side to the upper side, from the outer side to the inner side, in opposition to the display tilt.

Thus, a phenomenon in which the actual droplet and the reflected droplet meet each other is shown at the boundary where the visible body 210 and the display 160 meet. Such performances may enable the user to perceive the rain scene more effectively.

Fig. 34 is a schematic diagram showing the position of the 2 nd injection port of the second embodiment of the invention.

In the present embodiment, three 2 nd injection ports are arranged differently from the first embodiment.

The three 2 nd injection ports are arranged at 120 degree intervals. The three 2 nd injection ports are constituted by the 2 nd-1 st injection port 412, the 2 nd-2 nd injection port 413, the 2 nd-3 rd injection port 414.

Unlike the first embodiment, the 2 nd to 3 rd injection ports 414 may form a third injection line L3.

2-3 injection ports 414 may be disposed at a different height than 2-1 injection ports 412 or 2-2 injection ports 413. The 2-3 injection ports 414 may overlap the watering housing cover and may form a wider spray angle.

The rest of the structure is the same as that of the first embodiment, and thus a detailed description will be omitted.

Although the preferred embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to the specific embodiments described above, and various modifications can be made by those skilled in the art without departing from the technical spirit of the present invention claimed in the claims.
