Description

Humidification cleaning device {APPARATUS FOR HUMIDIFICATION AND AIR CLEANING}

The present invention relates to a humidification cleaning device, and more particularly, to a humidification cleaning device configured to reduce the flow resistance of a water tank humidification medium but not lack the humidification performance, so that the capacity can be increased and the output can be increased.

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 is rotated using driving force and water evaporates naturally from the surface of the disk in the air, and a humidification filter-type humidifier that is naturally evaporated by air flowing in a 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.

In order to solve this problem of the humidifier, Patent Publication No. 10-2017-0051176 discloses a technology related to a humidification cleaning device capable of independently operating a humidifying function and an air cleaning function.

The configuration disclosed in the prior document has a structure in which humidification is made by natural evaporation of water while air passes through a water tank humidification medium moistened with water.

On the other hand, the water tank humidification medium of the prior document is formed in a multi-layer structure, and multifilaments having hygroscopicity so that water can be wetted must be essentially provided in the middle layer of the multi-layer structure.

However, when multifilaments are provided in the intermediate layer of the water tank humidification medium as described above, the amount of humidification for passing air may be increased, but since a high differential pressure occurs between the front and rear sides of the water tank humidification medium, increase the amount of air discharged or increase the wind speed. If you want to increase the efficiency, there is a very high possibility that a sudden decrease in efficiency and power loss will occur.

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 .

(40), a humidifying medium 50 moistened by water sprayed from the water wheel unit 40 and providing moisture to the flowing air, and a visual body coupled to the water tank 30 and made of a material that can see the inside 210 and a top cover assembly 230 that is detachably mounted on the visual body 210 and has a discharge passage 107 through which air is discharged, and a water supply passage 109 through which water is supplied.

The water tank 30 is mounted on the mounting body 120 . The water wheel unit 40 is disposed inside the water tank 30 and rotates inside the water tank 30 .

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. Exemplarily 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 .

The direction indicating means may be formed in such a way that the display groove 304 is provided in the inner medium frame 310 and the display protrusion 302 is provided in the outer medium frame 320 and fitted. The display groove 304 and the display protrusion 302 are coupled by an interference fit method to fix the coupling between the inner media frame 310 and the outer media frame 320 .

The outer media frame 320 and the inner media frame 310 are coupled to each other in an interference fit manner. When the outer medium frame 320 and the inner medium frame 310 are press-fitted, the water tank humidification medium 51 is fixed.

In order to fix the water tank humidifying medium 51 , at least one of the outer medium frame 320 and the inner medium frame 310 may be provided with a humidifying medium fixing means for fixing the water tank humidifying medium 51 . Exemplarily in this embodiment, the humidifying medium fixing means may be composed of a projection and a hole.

The humidifying medium fixing means is formed on the other one of the fixing protrusion 308 formed on either the inner medium frame 310 or the outer medium frame 320, and the inner medium frame 310 or the outer medium frame 320, It includes a fixing hole 306 into which the fixing protrusion 308 is fitted. The number of fixing protrusions 308 and fixing holes 306 according to the present embodiment can be changed within a corresponding range.

In this embodiment, the fixing protrusion 308 is formed in the inner medium frame 310 , and the fixing hole 306 is formed in the outer medium frame 320 . Unlike the present embodiment, the position may be reversed. The fixing part 54 of the water tank humidification medium 51 is disposed between the fixing protrusion 308 and the fixing hole 306 , and when the fixing projection 308 is inserted into the fixing hole 306 , the water tank humidifying medium 51 is disposed. ) is fixed to the water tank humidification medium housing 300 .

The fixing protrusion 308 and the fixing hole 306 prevent the water tank humidification medium 51 from moving between the inner medium frame 310 and the outer medium frame 320 .

In this embodiment, a hole in which the fixing hole 306 is vertically opened in the outer upper frame 322 of the outer medium frame 320 is formed.

The fixing protrusion 308 is disposed on the inner upper frame 312 of the inner medium frame 310 and is formed to protrude downward from the lower surface of the inner upper frame 312 .

There is also an effect of being coupled to the inner media frame 310 and the outer media frame 320 by the coupling of the fixing protrusion 308 and the fixing hole 306 .

On the other hand, the outer medium frame 320 is provided with a guide wall 315 that defines the flow direction of the water moving toward the water tank humidification medium 51 after the water is scattered by a water wheel.

More specifically, 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.

As will be described later, the wind speed F1 of the air at the upper side of the water tank humidifying 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, so 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 water tank humidification medium 51 will be splashed upward by the pressure of the air.

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 first guide wall 315a and a second guide wall 315b.

The plurality of first guide walls 315a are formed to protrude 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).

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 . Exemplarily, the first guide wall 315a is the third ring-shaped surface 312a3 among the first ring-shaped surface 312a1, the second ring-shaped surface 312a2, and the third ring-shaped surface 312a3 of the inner upper frame 312. It is formed on the inner edge 312a4.

The plurality of second guide walls 315b are formed integrally with one end 315a2 and the other end 315a3 of the first guide wall 315a, respectively, and are formed to protrude upward from the inner frame 313 .

The second guide wall 315b serves to additionally prevent the water passing through the above-described 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

The water passing through the gap g between the first guide walls 315a moves downwardly along the inner frame 313 by the pair of second guide walls 315b. The width of this separate flow channel is gradually reduced as it proceeds in the downward direction so that water is effectively guided downward and the phenomenon of water crossing over the first guide wall 315a and the second guide wall 315b can be prevented. It can be configured to

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

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

On the other hand, as shown in Figure 9, the plurality of first guide walls (315a), the plurality of second guide walls (315b) and the plurality of guide projections 316 are symmetrical with respect to the central axis (X) of the humidification cleaning device. It is configured to be formed in a position to be.

Through this, it is moved in the circumferential direction by the first guide wall 315a, moved downward along the second guide wall 315b, and then divided by the guide protrusion 316 and supplied to the water tank humidification medium 51. The amount of water can be maintained substantially uniformly along the circumferential direction, and it is possible to prevent a phenomenon in which the humidifying effect of the water tank humidification medium 51 is partially biased.

Meanwhile, the water tank humidification medium 51 is disposed between the inner medium frame 310 and the outer medium frame 320 . The water tank humidification medium 51 covers the water tank inlet 31 . In this embodiment, the water tank humidifying medium 51 is formed in the form of a hopper with a small lower cross-sectional area and a large upper cross-sectional area.

The water tank humidifying medium 51 includes at least one fixing part 54 for fixing to the water tank humidifying medium housing 300 . The fixing part 54 is formed in a number equal to or smaller than the number of the fixing protrusions 308 and the fixing holes 306 . The fixing part 54 has a ring shape and is disposed on the upper side of the water tank humidification medium 51 . The fixing part 54 is fixed between the fixing protrusion 308 and the fixing hole 306 . The water tank humidification medium 51 has a fixing part 54 fixed between the fixing protrusion 308 of the inner medium frame 310 and the fixing hole 306 of the outer medium frame 320, the inner medium frame 310 and It does not move between the outer media frames 320 .

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 an upwardly inclined flow rather than a horizontal movement. 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.

On the other hand, the water tank humidification medium 51 of the present invention serves as a humidifying filter that absorbs water and humidifies the flowing air by evaporating water naturally.

To this end, as shown in FIG. 13 , the humidifying filter 52 forms a double cell layered structure including a first surface layer 51a, an intermediate layer 51b, and a second surface layer 51c.

The double cell structure is also called a 3D mesh, and the first surface layer 51a and the second surface layer 51c have a polygonal, preferably, a hexagonal lattice structure.

The first surface layer 51a and the second surface layer 51c having a double cell structure are spaced apart from each other by a predetermined distance, and an intermediate layer 51b to be described later between the first surface layer 51a and the second surface layer 51c. ) is formed.

As described above, an object of the present invention is to reduce the pressure difference between the front and rear of the water tank humidifying medium 51 by lowering the flow resistance of the water tank humidifying medium 51 . This object can be partially achieved by lowering the flow resistance of the first surface layer 51a and the second surface layer 51c compared to the prior art.

The flow resistance in the first surface layer 51a and the second surface layer 51c is related to the size of the unit hexagonal lattice 51h forming the Raschel structure, and as shown in FIG. 12, the unit hexagonal lattice 51h The size of can be defined by the grid width (CW) in the horizontal direction and the grid length (CL) in the vertical direction.

On the other hand, it is known that the size of the hexagonal grid is related to the total width of the fabric used for manufacturing the first surface layer 51a and the second surface layer 51c and the number of grid rings constituting the unit hexagonal grid 51h. there is. That is, as the overall width of the fabric increases and the number of lattice rings cos increases, the size of the unit hexagonal grid 51h increases.

Conventionally, the first surface layer 51a and the second surface layer 51c were manufactured using a fabric having an overall width of 60 inches and a grid number of 12, but in the present invention, the total width is 70 inches and a grid The first surface layer 51a and the second surface layer 51c are manufactured using the fabric having the number of rings of 24.

Accordingly, the size of the unit hexagonal grid 51h is significantly increased compared to the conventional one. In the present invention, the lattice width (CW) and lattice length (CL) of the unit hexagonal lattice 51h are formed larger than before, so that the flow resistance of air by the first surface layer 51a and the second surface layer 51c is increased. can be reduced, and accordingly, the differential pressure in the front and rear of the water tank humidifying medium 51 can be reduced.

On the other hand, the first surface layer (51a) and the second surface layer (51c) may be formed by weaving a multifilament (51g) formed by twisting a plurality of nylon fibers in the same manner in a raschel structure, preferably, it is known in the art. A nylon multifilament (51g) having a known 280D/96F specification may be applied.

At this time, the total content of the sum of the first surface layer (51a) and the second surface layer (51c) based on 100% by weight of the water tank humidifying medium 51 is preferably 35 to 40% by weight.

If the total content is less than 35% by weight, the ability to support and maintain the intermediate layer 51b may be reduced, and if it exceeds 40% by weight, the air by the first surface layer 51a and the second surface layer 51c may be reduced. This is because the flow resistance increases.

The intermediate layer (51b) serves to absorb water and naturally evaporate the absorbed water by the air passing through the water tank humidification medium (51). Water supplied to the water tank humidification medium 51 is partially absorbed by the first surface layer 51a and the second surface layer 51c, but most of the water is absorbed by the intermediate layer 51b.

However, unlike the prior art, the intermediate layer 51b of the present invention consists only of a plurality of monofilament fibers 51f having non-absorption. That is, it is possible to significantly reduce the flow resistance of air passing through the intermediate layer 51b by excluding the multifilament responsible for moisture absorption as in the prior art.

However, since the monofilament fiber 51f itself has no absorption capacity, it is configured so that water is absorbed in the space formed between the monofilament fibers 51f, and the intermediate layer 51b is formed to increase the absorption performance of the intermediate layer 51b. The content of the constituting monofilament fibers (51f) is configured to be increased more than twice as compared to the prior art.

More specifically, the content of the intermediate layer (51b) based on 100% by weight of the water tank humidifying medium 51 is preferably 60 to 65% by weight.

This is because when the total content is less than 60% by weight, the moisture absorption of the intermediate layer 51b may be reduced, and when it exceeds 65% by weight, the flow resistance of air by the intermediate layer 51b is increased.

On the other hand, in order to form a double cell layered structure, the first surface layer 51a is fusion-bonded to the upper surface of the intermediate layer 51b, and the second surface layer 51c is fusion-bonded to the lower surface of the intermediate layer 51b. Through such fusion bonding, it is possible to prevent the occurrence of fluff or the like due to sewing.

On the other hand, 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.

The water tank humidification medium 51 of the present invention is configured to increase the humidification effect on the air according to the flow rate of the passing air and to reduce the flow resistance of the air to the intermediate layer 51b.

That is, as shown in FIG. 14, with respect to the hopper-shaped water tank humidification medium 51, the middle layer 51b while proceeding from the lower end 51d with the lowest speed of passing air to the upper end 51e with the highest speed of passing air. content is changed.

In more detail, it is configured such that the content of the intermediate layer 51b is increased while proceeding from the lower end 51d having the lowest speed of passing air to the upper end 51e having the highest speed of passing air.

Through such a configuration, by increasing the content of the intermediate layer (51b) in proportion to the speed of passage ventilation, the pressure difference between the front and rear of the water tank humidifying medium (51) is maintained at a predetermined level, but the humidification effect on the air can be significantly increased. there will be

Exemplarily, the content of the intermediate layer 51b may be gradually increased while proceeding from the first area A1 having the lowest moving speed of the passing air to the second area A2 having the highest moving speed of the passing air.

At this time, the content of the intermediate layer 51b is maintained in the range of 60 to 65% by weight, but increases proportionally and continuously while proceeding to the first area A1, the second area A2, and the third area A3. can However, the total weight ratio of the entire intermediate layer 51b is maintained constant.

As another example, the content of the intermediate layer 51b may be increased step by step while proceeding from the first area A1 having the lowest moving speed of the passing air to the second area A2 having the highest moving speed of the passing air.

In this case, the content of the intermediate layer 51b may be increased stepwise through the first region A1, the second region A2, and the third region A3 while maintaining the range of 60 to 65% by weight. Similarly, however, the total weight ratio of the entire intermediate layer 51b is maintained constant.

In this way, the content of the intermediate layer 51b is differentiated for each area (A1, A2, A3), but the total weight ratio of the intermediate layer 51b is maintained constant. is increased, but the manufacturing cost of the water tank humidification medium 51 can be reduced.

14 shows an embodiment in which the water tank humidification medium 51 is equally divided into a first area A1, a second area A2, and a third area A3 along the vertical direction, but this is merely exemplary and The heights or widths of the first area A1 , the second area A2 , and the third area A3 may be set differently from each other.

Hereinafter, the effect of the present invention will be described in detail by comparing the experimental results of Examples and Comparative Examples for the water tank humidification medium 51 according to the present invention.

<Comparative Example 1>

To have the same configuration as in the prior art, the first surface layer 51a and the second surface layer 51c are made of a nylon multifilament having a 280D/96F specification so that the overall width is 60 inches and the number of lattice rings is 12 It was manufactured by cutting the fabric.

The intermediate layer 51b was prepared by mixing multifilaments of PET material having 75D/36F specifications and monofilaments having 0.12mm PET material in approximately the same weight ratio.

<Comparative Example 2>

The first surface layer 51a and the second surface layer 51c of Comparative Example 2 were made of nylon multifilament having the same 280D/96F specifications as in Comparative Example 1, but the overall width was 70 inches and a lattice ring The number was manufactured by cutting the fabric to be 24.

The intermediate layer 51b was prepared by mixing multifilaments of PET material having 75D/36F specifications and monofilaments having 0.12mm PET material in approximately the same weight ratio as in Comparative Example 1.

<Comparative Example 3>

The first surface layer 51a and the second surface layer 51c of Comparative Example 3 were manufactured to have the same specifications as those of Comparative Example 2.

Unlike Comparative Example 2, the intermediate layer 51b was manufactured only with monofilaments having 0.12 mm PET material, excluding multifilaments made of PET having 75D/36F specifications. At this time, since the multifilaments made of PET are excluded, the weight ratio of the intermediate layer 51b of Comparative Example 3 is half that of Comparative Examples 1 and 2.

<Example>

The first surface layer 51a and the second surface layer 51c of the example were manufactured to have the same specifications as those of Comparative Examples 2 and 3.

The intermediate layer 51b was prepared only with monofilaments having a PET material of 0.10 mm, but by increasing the amount of monofilaments to have a weight ratio twice the content of monofilaments having a PET material applied in Comparative Example 3 by weight.

<Test conditions>

In order to compare the flow resistance of the water tank humidifying medium 51 prepared for each condition, the differential pressure before and after the water tank humidifying medium 51 for each comparative example and example was measured using the same pressure sensors at the same location. The differential pressure was measured by calculating the difference between the pressure of the air just before entering the water tank humidifying medium 51 in the air flow direction and the air pressure measured at 10 cm behind the water tank humidifying medium 51 .

In addition, in order to compare the humidification capacity of the water tank humidifying medium 51 manufactured for each condition, the amount of humidification per hour of the water tank humidifying medium 51 for each comparative example and example was measured using the same humidity sensor at the same location. The amount of humidification per hour (cc/h) was measured at 10 cm behind the water tank humidification medium 51 .

<Test result>

15 shows differential pressure data and humidification data of each comparative example and example measured according to the above-described test conditions.

Referring to FIG. 15 , in Comparative Example 1 and Comparative Example 2 having the same specifications as in the prior art, the measured differential pressure data were all measured to exceed 2.5 mmAq.

However, both Example and Comparative Example 3 showed differential pressure data of 2 mmAq face. Through this, by reducing the size of the unit hexagonal lattice 51h of the first surface layer 51a and the second surface layer 51c and excluding multifilaments from the intermediate layer 51b, the flow resistance of the water tank humidification medium 51 is significantly reduced. It has been confirmed that it is possible

In addition, in Examples, the humidification amount per hour was significantly lower than those of Comparative Examples 1 and 2, but the intended target value of humidification was found to be exceeded. On the other hand, in the case of Comparative Example 3, a value of 600 cc/h or less was shown, which was less than the amount of humidification per hour, which was insufficient in the content of the monofilament fibers 51f in the intermediate layer 51b, that is, the spacing between the monofilaments. Because this is too large, it can be judged to indicate the fact that it is difficult to retain water for humidification between the monofilaments.

As described above, the present invention has been described with reference to the illustrated drawings, but the present invention is not limited by the embodiments and drawings disclosed in this specification, and various methods can be obtained by those skilled in the art within the scope of the technical spirit of the present invention. It is obvious that variations can be made. In addition, although the effects according to the configuration of the present invention have not been explicitly described and described while describing the embodiments of the present invention, it is natural that the effects predictable by the configuration should also be recognized.
