Description

Humidification cleaning device

The present invention relates to a humidification cleaning device, and more particularly, to a humidification cleaning device capable of fundamentally blocking the water splash phenomenon in which water scattered through a water wheel is bounced to the outside by the pressure of filtered air regardless of the blowing strength.

An air conditioner is a concept including an air conditioner that controls the temperature of air, an air purifier that maintains cleanliness by removing foreign substances from the air, a humidifier that provides moisture to the air, and a dehumidifier that removes moisture from the air.

Among them, the conventional humidifier is divided into a vibrating type in which water is atomized on a diaphragm and discharged into the air, and a natural evaporation type in which a humidification filter naturally evaporates water.

The natural evaporative humidifier is divided into a disc-type humidifier in which the disk rotates using driving force and water evaporates naturally from the surface of the disk in the air, and a humidification filter-type humidifier in which water is naturally evaporated by the air flowing in the humidifying medium moistened with water. can be

In the conventional humidifier, some of the air flowing during the humidification process was filtered by the filter. However, the conventional humidifier has a problem in that the function of purifying the air is rather weak because the humidification function is a key function.

In addition, since the conventional humidifier has a structure in which a filtering function is added during the humidification process, there is a problem that it cannot be operated only for air filtering.

The mounting body 120 is concavely formed inside the base body 110 , and the water tank 30 can be accommodated in the base body 110 . Through this, the center of gravity of the humidification cleaning device can be moved to the lower side.

The humidification cleaning apparatus according to this embodiment receives power through the clean module 100 and provides power to the humidification module 200 through the clean module 100 . Since the humidification module 200 has a separable structure with respect to the clean module 100, the clean module 100 and the humidification module 200 are provided with a separable power supply structure.

That is, since the clean module 100 and the humidification module 200 are connected through the mounting body 120 , the connector 260 for providing power to the humidification module 200 is disposed on the mounting body 120 . .

Meanwhile, the filter assembly 10 is detachably assembled to the base body 110 .

The water wheel unit 40 sucks the water inside the water tank 30 , pumps the sucked water upward, and sprays the pumped water outward in the radial direction.

The water wheel unit 40 includes a water wheel housing 80 that sucks water inside, pumps the sucked water upward, and then sprays it radially outward.

Water sprayed from the water turbine housing 80 wets the humidifying medium 50 . To this end, the water sprayed from the water turbine housing 80 may be sprayed toward at least one of the visual body 210 and the humidifying medium 50 .

Exemplarily in this embodiment, the water wheel housing 80 sprays water toward the inner surface of the visual body 210, and the sprayed water flows down by gravity along the inner surface of the visual body 210.

Droplets formed in the form of water droplets are formed on the inner surface of the visual body 210 , and the user can observe the droplets through the visual body 210 .

The visual body 210 is coupled to the water tank 30 and is disposed on the upper side of the water tank 30 . At least a portion of the visual body 210 is formed of a transparent material that can control the interior.

The droplets formed on the inner surface of the visual body 210 may implement a form in which raindrops are formed. The droplets flowing down from the visual body 210 move in the downward direction to wet the humidifying medium 50 .

The display module 160 may be disposed outside the visual body 210 . The display module 160 is coupled to either the visual body 210 or the mounting body 120 . Exemplarily in this embodiment, the display module 160 is disposed on the mounting body 120 .

When the humidification module 200 is mounted, the outer surface of the visual body 210 is in close contact with the display module 160 . At least a portion of the surface of the display module 160 is formed of a material that reflects light.

The droplets formed on the inner surface of the visual body 210 are also projected on the surface of the display module 160 . Through this, 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 30 is formed with a water tank inlet 31 through which air is communicated. The air supplied from the clean module 100 flows into the humidification module 200 through the water tank inlet 31 .

The humidifying medium 50 includes a water tank humidification medium 51 disposed in the connection flow path 103 and a discharge humidifying medium 55 disposed in the discharge flow path 107 .

The water tank humidification medium 51 covers the water tank inlet 31 , and air flows through the water tank humidifying medium 51 into the water tank 30 .

The discharge humidifying medium 55 is disposed on the discharge passage 107 . The discharge humidifying medium 55 may be disposed on at least one of the visual body 21 and the top cover assembly 230 . Exemplarily in this embodiment, the discharge humidifying medium 55 is disposed on the top cover assembly 230 .

The discharge humidifying medium 55 covers the discharge passage 107 , and air passes through the discharge humidifying medium 55 and is discharged out of the top cover assembly 230 .

Hereinafter, the flow of air will be described with reference to FIG. 5 .

When the blowing unit 20 is operated, external air is introduced into the base body 110 through the suction passage 101 formed on the lower side of the base body 110 . The air sucked in through the suction passage 101 is moved upward, passes through the clean module 100 and the humidification module 200, and is discharged to the outside through the discharge passage 107 formed at the upper side of the humidification module 200. .

The air sucked into the suction passage 101 passes through the filter passage 102 of the filter assembly 10 . While passing through the filter passage 102, the filter assembly 10 filters the outside air.

The air passing through the filter passage 102 flows to the connection passage 103 through the blowing unit 20 . The air that has passed through the filter passage 102 is pressurized by the blower fan 24 and then flows along the blower housing 150 to the connection passage 103 .

Since the blowing unit 20 is disposed after the filter passage 102 , it is possible to minimize the attachment of foreign substances such as dust to the blowing fan 24 . When the blowing unit 20 is disposed before the filter passage 102 , foreign substances are attached to the blowing fan 24 , which may cause a problem in that the cleaning cycle is shortened.

In addition, since the blowing unit 20 is disposed before the humidification passage 106 to be described later, it is possible to minimize the adhesion of moisture to the surface of the blowing fan 24 . When the humidified moisture is attached to the surface of the blowing fan 24, there is a very high risk that foreign substances may be agglomerated or mold may be generated. Since the blowing unit 20 is disposed between the filtration flow path 102 and the humidification flow path 106 , it is possible to minimize the adhesion of foreign substances and to provide an appropriate flow pressure of air.

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

When the humidification module 200 is mounted on the mounting body 120 , the clean connection passage 104 and the humidification connection passage 105 are connected. When the humidification module 200 is in a separated state, 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 mounting body 120 , and the humidification connection passage 105 may be formed in the humidification module 200 .

The clean connection flow path 104 and the humidification connection flow path 105 may be formed in a duct shape to form a clear flow path. Illustratively in this embodiment, when the connection flow path 103 is distributed to some structures of the mounting body 120 and some structures of the water tank 30 , and the humidification module 200 is mounted on the mounting body 120 , the A connection passage 103 is formed.

In this embodiment, the mounting body 120 provides an outer structure of the connection passage 103 , and the water tank 30 provides an inner structure of the connection passage 103 .

That is, the connection passage 103 is formed between the outside of the water tank 30 and the inside of the mounting body 120 . Through this, the connection passage 103 is formed between the water tank 30 and the mounting body 120 . The water tank 30 forms an inner wall of the connection passage 103 , and the mounting body 120 forms an outer wall of the connection passage 103 .

By distributing the structure of the connection flow path 103 as described above, there is an advantage in that the structure forming the flow path can be minimized. The connection passage 103 is formed in the vertical direction.

On the other hand, the air that has passed through the connection passage 103 flows into the humidification passage 106 . The humidification passage 106 is a section in which moisture is supplied to the air. In this embodiment, the humidification flow path 106 may be from the water tank humidification medium 51 to the discharge humidification medium 55 .

While passing through the water tank humidification medium 51 in the connection flow path 103, moisture may be supplied to the air. In addition, water droplets scattered from the water turbine unit 40 and water evaporated from the water tank 30 are provided inside the water tank 30 .

In addition, while passing through the discharge humidifying medium 55 inside the water tank 30, moisture may be supplied again.

In the humidification passage 106 , moisture is supplied through the water tank humidification medium 51 , the inside of the water tank 30 , and the discharge humidification medium 55 .

Finally, the air that has passed through the discharge humidifying medium 55 is exposed to the outside through the discharge passage 107 .

The water tank humidification medium 51 is disposed inclined with respect to the vertical direction. The inclination of the water tank humidification medium 51 considers the air flow direction.

The air flowing into the water tank inlet 31 through the connection passage 103 forms a flow inclined upward rather than horizontally. The tank humidifying medium 51 formed to be inclined may be disposed to be perpendicular to the air flow direction.

When the air flow and the water tank humidifying medium 51 are orthogonal to each other, it is possible to prevent air from being drawn to a specific part of the water tank humidifying medium 51, and air can pass through the entire area evenly.

The water tank humidification medium 51 uses a material having excellent moisture absorption performance in order to secure the humidification performance. For example, the water tank humidification medium 51 may be formed of a material made of polyethylene terephthalate (PET) having excellent moisture absorption performance.

On the other hand, as described above, in the humidification cleaning device according to an embodiment of the present invention, before the water scattered through the water tank is absorbed by the water tank humidifying medium 51, the pressure of the filtered air passing through the water tank humidifying medium 51 is applied. The purpose of this is to prevent water splashing from being thrown to the outside.

As a means for preventing such splashing phenomenon, the humidification cleaning device according to an embodiment of the present invention is provided at the upper end of the water tank humidification medium housing 300, and after the water is scattered by a water wheel, the water tank humidification medium 51 It further includes a guide wall 315 defining the flow direction of the water moving toward the.

As described above, the water sprayed or scattered by the aberration moves along the inner surface of the visual body in the downward direction by gravity in the form of droplets.

The moving droplet in the downward direction reaches the upper portion of the inner medium frame 310 of the water tank humidification medium housing 300 . In more detail, the droplet reaches the upper surface 312a of the inner upper frame 312 of the inner medium frame 310, and is then moved to the water tank humidification medium 51 by gravity and absorbed.

However, as shown in FIG. 6 , it was confirmed that the air moving upward through the water tank humidification medium 51 tends to increase in wind speed as it moves away from the central axis (X) of the humidification cleaning device.

Since the wind speed F1 of the air at the upper side of the water tank humidification medium 51 adjacent to the inner upper frame 312 is faster than the wind speed F2 at the middle side and the wind speed F3 at the lower side, the water tank directly from the inner upper frame 312 There is a high possibility that the water in the form of droplets moved to the upper side of the humidifying medium 51 will be splashed upward by the pressure of the air.

This water splash phenomenon is particularly highly likely to occur in a state in which the humidification cleaning device is operated at the maximum air volume.

In order to fundamentally block the occurrence of such a splashing phenomenon, the guide wall 315 is configured to block direct movement of the water sprayed or scattered by the water wheel to the upper side of the water tank humidification medium 51 .

In more detail, the guide wall 315 includes a plurality of first guide walls 315a protruding upward from the inner upper frame 312 of the inner medium frame 310 with a predetermined height.

At this time, the plurality of first guide walls 315a have an arc shape corresponding to the shape of the inner upper frame 312 having a ring shape and extend to a predetermined length, and the length to which the first guide wall 315a extends. corresponds to the interval between the adjacently arranged inner vertical frame (313).

That is, the first guide wall 315a extends between the adjacently arranged inner vertical frames 313 so that water directly from the upper side 312a of the inner upper frame 312 is directed toward the upper side of the water tank humidification medium 51 . It is configured to guide so as not to move.

On the other hand, as shown, a gap (g) having a predetermined width is formed between the first guide walls (315a) disposed adjacent to each other, and the gap (g) is water moving along the first guide wall (315a). It serves as a passage to flow to the inner frame (313).

In addition, the first guide wall 315a is formed to protrude from the inner edge 312a4 of the upper surface 312a of the inner upper frame 312 .

Through this, the cross-sectional area of the water flow channel c formed between the first guide wall 315a and the upper surface 312a of the inner upper frame 312 can be secured as much as possible, and through this, the water can directly flow into the first guide wall It is possible to prevent the phenomenon of moving to the upper side of the water tank humidification medium 51 over the ride (315a).

Furthermore, the upper surface 312a of the inner upper frame 312 of the humidification cleaning device according to an embodiment of the present invention is a first ring-shaped surface (312a1) formed in the outermost portion, and a first ring-shaped surface (312a1) of A second ring-shaped surface (312a2) provided on the radially inner side, and a third ring-shaped surface (312a3) formed on the radially inner side of the second ring-shaped surface (312a2) is configured to include.

Likewise, the third annular surface 312a3 is integrally formed with the second annular surface 312a2 and is configured to extend radially inwardly and downwardly with respect to the second annular surface 312a2.

At this time, the first guide wall 315a is formed to protrude upward from the inner edge 312a4 of the third ring-shaped surface 312a3.

The upper surface 312a of the inner upper frame 312 is configured in a three-dimensional ring shape, and the first guide wall 315a is formed in the radial direction as much as possible, so that the air passing through the water tank humidification medium 51 It is possible to secure the cross-sectional area of the flow channel c formed by the second ring-shaped surface 312a2, the third ring-shaped surface 312a3 and the first guide wall 315a as large as possible while minimizing the flow resistance.

On the other hand, as shown in FIG. 12 , the upper direction of the first guide wall 315a of the upper end 315a1 is higher than the upper direction of the first ring-shaped surface 312a1 . Through this, it is possible to prevent a phenomenon in which water directly passes over the first guide wall 315a and moves to the upper side of the water tank humidification medium 51 .

In addition, the humidification cleaning apparatus according to an embodiment of the present invention is formed integrally with one end (315a2) and the other end (315a3) of the first guide wall (315a), respectively, and upward from the inner frame (313). It further includes a plurality of second guide walls (315b) formed to protrude.

As described above, the water guided by the first guide wall 315a moves downward through the gap g formed between the adjacent first guide walls 315a.

The second guide wall 315b serves to additionally prevent the water passing through the gap g from moving to the upper side of the water tank humidification medium 51 .

To this end, the pair of second guide walls 315b are formed to protrude from the inner frame 313 in the form of enclosing the gap g, and move downward to a position outside the upper side of the water tank humidification medium 51 . is extended to

6 to 14 exemplarily show an embodiment in which the second guide wall 315b is integrally formed on the upper surface 313a of the inner frame 313 and protrudes from the left and right edges of the upper surface 313a, It will be seen that it is also possible to configure so as to protrude from the side of the inner frame 313 .

Water passing through the gap g between the first guide walls 315a moves along the upper surface 313a of the inner frame 313 in the downward direction by a pair of second guide walls 315b. do. That is, a separate flow channel for guiding water in the lower direction is formed by the pair of second guide walls 315b and the upper surface 313a of the inner frame 313 .

On the other hand, the width of this separate flow channel is effectively guided in the downward direction and proceeds in the downward direction to prevent the water from riding over the first guide wall (315a) and the second guide wall (315b). It is configured to gradually become smaller.

To this end, as shown in FIG. 13 , the interval d between a pair of adjacently disposed second guide walls 315b may be configured to gradually decrease while proceeding in the downward direction up to a predetermined range.

On the other hand, the water moving along the second guide wall (315b) is supplied to the water tank humidifying medium (51) at a position out of the upper side of the water tank humidifying medium (51).

At this time, the position where water is supplied is between the upper and lower middle position of the water tank humidifying medium 51 so that water can be evenly absorbed into the upper and lower sides of the water tank humidifying medium 51 without splashing water. is preferable to

A guide projection 316 on the upper side 313a of the inner frame 313 between the upper and lower middle position and the upper end of the water tank humidifying medium 51 so that water can be supplied to the water tank humidifying medium 51 at this position. is provided

The guide protrusion 316 is formed to protrude from the upper surface 313a of the inner frame 313 to a predetermined height, and along the upper surface 313a of the second guide wall 315b and the inner frame 313 . It serves to supply water to the water tank humidification medium 51 by switching the flow path of the moving water.

At this time, the water is divided in the left and right direction with respect to the guide protrusion 316 and moved to the water tank humidification medium 51. .

That is, the cross-sectional area of the front end 316a of the guide protrusion 316 is formed to be smaller than the cross-sectional area of the rear end 316b, and as it progresses toward the rear end 316b, the cross-sectional area may be gradually increased.
