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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Hereinafter, the flow of air will be described with reference to the drawings.

When the air blowing unit 20 is operated, the outside air flows into the base body 110 through the suction flow path 101 formed on the lower side of the base body 110. The air sucked through the suction passage 101 moves upward while passing through the air clean module 100 and the air wash module 200 in succession and the discharge passage 107 formed on the upper side of the air wash module 200 And is discharged to the outside.

The air sucked into the suction passage 101 passes through the filtering passage 102 of the filter assembly 10 and the filter assembly 102 filters the outside air.

The air that has passed through the filtration channel (102) flows into the connection channel (103) through the air blowing unit (20). The air that has passed through the filtration channel 102 flows into the airflow channel 108.

The filtered air is pressurized by the air blowing fan 24 in the air blowing passage 108, and then flows into the clean connection passage 104.

Since the air blowing unit 20 is arranged after the filtration flow path 102, it pressurizes the filtration air to blow air. It is possible to minimize the adherence of foreign matter such as dust to the blowing fan 24 through the rearward relative arrangement of the filter assembly 10 and the blowing unit 20.

When the air blowing unit 20 is disposed in front of the filtration flow path 102, the outside air first comes into contact with the blowing fan 24, so that the possibility that the foreign substance adheres to the blowing fan 24 is increased. If the blowing fan 24 is contaminated with foreign matter, the user must periodically clean it and provide a structure for cleaning the blowing fan 24.

Since the air blowing unit 20 according to the present embodiment blows the filtered air from which the foreign substances in the air are separated, it is not necessary to perform separate cleaning.

Further, since the blowing unit 20 is disposed in front of the humidification channel 106, adhesion of moisture to the surface of the blowing fan 24 can be minimized. When the humidified moisture adheres to the surface of the blowing fan 24, there is a high possibility that the foreign matter may get clogged or mold or the like may be generated.

Since the air blowing unit 20 is disposed after the filtration flow path 102 and before the humidification flow path 106, contamination of the air blowing unit 20 can be minimized.

The connection passage 103 is composed of a clean connection passage 104 formed in the air clean module 100 and a humidification connection passage 105 formed in the air wash module 200.

When the air wash module 200 is mounted on the upper body 120, the clean connection passage 104 and the humidification connection passage 105 are connected. When the air wash module 200 is disconnected, the clean connection passage 104 and the humidification connection passage 105 are exposed to the outside.

The clean connection passage 104 may be formed in the upper body 120 and the humidification connection passage 105 may be formed in the air wash module 200.

The clean connection passage 104 and the humidification connection passage 105 may be formed in the form of a duct to form a clear flow passage. In this embodiment, the connecting flow path 103 is dispersedly disposed in the structure of the upper body 120 and the structure of the water tank 300.

The connection passage 103 may be formed through a configuration such as a duct. However, when air is supplied into the water tub 300 through a structure such as a duct, a flow resistance due to the duct is significantly generated, and it is difficult to secure a sufficient flow rate. If the flow rate to be supplied to the water tank 300 is limited, the RPM of the blowing fan 24 must be increased, and the power consumption and noise due to this increase are increased.

In this embodiment, the connection channel 103 provides air to the water tank 300 in all directions 360 degrees, and a sufficient flow rate can be ensured through the air.

The filtered air having passed through the air passage 108 flows into the clean connection passage 104 formed in the upper body 120. An air guide 170 is disposed in the clean connection passage 104 of the upper body 120 to minimize the switching of the flow direction of the filtered air. The air guide 170 minimizes the switching angle of the filtered air.

In this embodiment, since the upper inner body 140 is disposed in the upper body 120 to form the water tank insertion space 125, the clean connection channel 104 and the air wash inlet 31 are directly connected.

The outer wall of the water tank 300 provides the humidification connection passage 105 when the height of the upper inner body 140 is short or absent. That is, when only the bottom 141 of the upper inner body 140 is provided and there is no side wall, the outside of the side wall of the water tub 300 provides the humidification connection flow path 105, And when the water tank 300 is mounted on the floor 141, the connection passage 103 is connected.

In the present embodiment, the filtered air in the clean connection passage 104 passes through the upper inlet 121 and the air-wash inlet 31 in order, passes through the water tank humidifying medium 51, and flows into the humidification passage 106 .

The humidification channel 106 is a section where moisture is supplied to the filtered air. In the present embodiment, the humidification channel 106 is a channel or space from the water tank humidifying medium 51 to the discharge humidifying medium 55.

In the humidification channel 106, humidification is performed through various paths.

First, in the course of filtering air passing through the water tank humidifying medium 51, moisture of the water tank humidifying medium 51 is naturally evaporated, and water can be supplied to the filtering air.

Secondly, water can be supplied to the filtered air by the water droplets scattered in the watering unit 400.

Third, humidification can be performed by moisture evaporated in the water tank 300.

Fourth, even when the filtered air passes through the discharge humidifying medium 55, the water wetted by the discharge humidifying medium 55 is naturally evaporated, and moisture can be supplied to the filtered air.

In this way, the filtered air can be supplied with water through various routes when passing through the humidification channel 106.

The air having passed through the discharge humidification medium 55 is exposed to the outside through the discharge flow path 107.

The air filtered and humidified through the discharge passage 107 is discharged. The discharge passage 107 discharges air 360 degrees in the forward and upward directions.

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