Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk for a humidifier,

The present invention relates to a disk for a humidifier and a method of manufacturing the same.

Generally, a humidifier is a device which includes moisture in the air to increase humidity in the air. The humidifier may be classified into an ultrasonic humidifier using ultrasonic vibration and a natural vaporization type humidifier in which the air is brought into contact with the air so that moisture is contained in the air.

Korean Patent Laid-Open No. 10-2012-0136137, which is a prior art document, discloses the structure of a humidifying air purifier.

In the prior art, a suction port is formed on the side of the upper case, a discharge port is formed on the upper surface, and a centrifugal fan is provided on the inner side of the upper case. In addition, a disk assembly having a plurality of disks coupled to the lower case is rotatably mounted, and a part of the disk assembly is locked to the water stored in the lower case to supply water to the surface of the disk.

In the humidifying air purifier according to the prior art, when the blowing fan is driven while the disk assembly rotates, air introduced from the suction port moves upward while passing through the disk, so that the humidified air can be discharged upward .

In the humidifiers having such a structure, the amount of humidification can be determined by the amount of water that can be absorbed by the disk, and the size and number of the disk are appropriately adjusted in order to secure a humidification amount. However, increasing the size and number of discs will affect the overall size, weight and productivity of the product.

Therefore, in order to solve such a problem, it is possible to coat the surface of the disk with a hydrophilic coating so that the disk can have more moisture. However, if the disc is coated one by one, not only the productivity is lowered and the manufacturing cost is increased, but also the coating is peeled off during use, resulting in the formation of suspended matters.

In order to solve this problem, Korean Patent Laid-Open Publication No. 10-2011-0107569 discloses a disc in which a plurality of ribs are protruded at regular intervals on both sides of the disc, and a pattern is formed between the plurality of ribs, A disk having a structure is disclosed.

Korean Patent Laid-Open No. 10-2010-0079634 discloses a disk for a humidifier having a structure in which a plurality of blades are formed at regular intervals on both sides of a disk and a plurality of protrusions are formed between the blades.

However, since the conventional disks having the above structure have a structure in which water is trapped by a plurality of ribs protruding in the circumferential direction as a whole, the pattern or protrusion is formed again between the plurality of ribs, In addition, the adsorption amount of water is not excellent.

An object of the present invention is to provide a disk for a humidifier in which a fine pattern formed by grooves in which lattice-like moisture is adsorbed on both sides of a disk of a vaporization type humidifier is provided so that the adsorption amount of water can be increased and productivity can be improved at the same time, And to provide a method.

A disk for a humidifier according to an embodiment of the present invention is a disk for a humidifier in which a plurality of sheets are rotatably arranged and moisture is continuously adsorbed in one configuration of a vaporization type humidifier, And a fine pattern defined by lattice-shaped grooves and projections formed by the grooves are formed.

The grooves are formed to be inclined, and the plurality of grooves are perpendicular to each other.

And the plurality of grooves are formed to be connected to each other.

And the cross-sectional shape of the projection is formed in a rhombic shape.

And the cross-sectional area of the projection becomes smaller as it goes toward the protruding direction.

Wherein a distance between one side of the projection and a vertex of the projection and a depth of the groove have a ratio of 1: 2: 0.3.

The disc further includes a plurality of reinforcing ribs extending radially outward from a center of the disc and radially disposed at a predetermined angle.

The method for manufacturing a humidifier disk according to an embodiment of the present invention is characterized in that the humidifier disk is formed by injection molding with a metal mold that is etched in a shape corresponding to the pattern.

According to the present invention, moisture can be adsorbed on the pattern by a pattern defined by fine grooves and protrusions on both sides of the disk. In this case, when the moisture is introduced into the pattern in the form of a lattice, water can be evenly distributed throughout the lattice, and rhombic protrusions formed by the lattice shape are uniformly distributed over the disc, so that moisture between the protrusions can be agglomerated. Such a water adsorption structure provides a uniform surface tension in all directions, thereby enhancing the adsorption performance of water. Also, as the moisture adsorbability of the disk is improved, the humidifying performance of the humidifier can be improved.

As the moisture adsorbability of the disc is improved, the number of the discs constituting the disc assembly can be reduced, thereby reducing the manufacturing cost of the product.

A method of manufacturing a disk for a humidifier according to an embodiment of the present invention is characterized in that a corresponding shape is formed in the mold by etching so as to form a lattice pattern formed on the surface of the disk, The disk is injection-molded. Therefore, it is possible to rapidly mold the disk by injection without additional post-processing, thereby improving the productivity and reducing the manufacturing cost.

Particularly, even if the lattice pattern of the disk formed by such a mold is not accurate, if a lattice pattern forming the entire flow path of moisture appears, excellent moisture adsorption performance can be obtained and productivity can be greatly improved The effect can be expected.

4 is a plan view of the disk of the humidifier.

The disk 71 is formed in the shape of a thin disk and a boss having the shaft hole 711 protruded from the center of the disk 71 712 and a plurality of ribs 713 are formed toward the outer end of the disk 71 with the shaft hole 711 as a center. The ribs 713 serve to reinforce the strength of the disc 71, which prevents shaking due to airflow and prevents the disc 71 from being broken easily. The ribs 713 are rotatably arranged at an angle around the shaft hole 711 and extend with a predetermined length.

In addition, a large number of fine patterns 714 are formed on the front surface and the back surface of the disk 71. The pattern 714 has a very small shape when viewed from the naked eye and appears as a simple concavo-convex shape. However, when the pattern 714 is enlarged, the grooves 715 are formed so as to intersect with each other, and the grooves 715 form the grooves 715 The protrusion 716 is formed naturally.

The grooves 715 and the protrusions 716 form a pattern 714 over the entire surface of the disk 71. The grooves 715 are formed at one end of the disk 71 or at the other end of the shaft hole 711). Therefore, the grooves 715 formed on the entire disc 71 can be connected to each other, and the water moved along the grooves 715 can be diffused over the entire disc 71.

The grooves 715 may extend obliquely and may be disposed at right angles to the other grooves 715 intersecting with each other. Therefore, the protrusion 716 formed by the groove 715 has a rhombic cross section. The protrusions 716 are formed in the shape of a quadrangular pyramid having a smaller cross section in the protruding direction.

That is, the groove 715 is defined by the protrusion 716, and has a shape that is recessed as compared with the protrusion 716, and the protrusion 716 has a shape in which the cross- . Accordingly, water can be received in the spaces defined by the grooves 715 and the protrusions 716, and water can be maintained in a state where surface tension is maintained.

The amount of water adsorbed on the disk 71 differs depending on the shape and size of the protrusion 716 and the distance therebetween, and will be described in more detail below.

5 is a graph showing the results of simulation comparing moisture adsorption amounts according to pattern shapes of a disk according to an embodiment of the present invention.

5A, 5B, 6C, and 6D show a case where the cross section of the protrusion 716 formed on the disc 71 has a square shape (a), a diamond shape (b), a triangle shape (c) The entire disc 71 was immersed in water and then lifted up to simulate changes in the amount of water adsorbed over time to visualize it. The time increased from the bottom to the top, and the moisture decreased as the color changed from red to blue it means.

When the cross-sectional shape of the protrusion 716 is a square, the amount of water adsorbed per unit time is 2.347e -6 kg. The amount of moisture adsorbed immediately after the disc 71 is immersed and removed is not so large, It can be seen that it is maintained for a long time.

When the cross-sectional shape of the protrusion 716 is rhombic, the amount of water adsorbed per unit time is 2.421e -6 kg. Not only is the amount of water adsorbed immediately after the disc 71 is dipped in and removed, It can be seen that the adsorbed amount is maintained for the longest time without decreasing the amount.

When the cross-sectional shape of the projection 716 is triangular, the amount of water adsorbed per unit time is 2.155e -6 kg, and the amount of moisture adsorbed immediately after the disk 71 is dipped and removed is relatively large. However, It can be seen that the amount of water adsorption is the lowest in the whole because the water flows rapidly and the amount of water adsorption after the middle is low.

When the protrusion 716 has a circular cross-sectional shape, the amount of water adsorbed per unit time is 2.309e -6 kg, and the amount of moisture adsorbed immediately after the disc 71 is dipped and removed is large. However, Particularly, it can be seen that the adsorption amount of water at the protrusion 716 is relatively low.

That is, when the cross-sectional shape of the protrusion 716 is rhombic, it can be seen that the most amount of adsorption is shown for a unit time, and that the adsorption amount of moisture is different in the order of a square, a circle and a triangle.

6 is a graph showing the results of simulation comparing moisture adsorption amounts according to pattern sizes of the disc according to the embodiment of the present invention.

6 shows a comparison between the case where the pattern 714 of the disc 71 is absent (Plate model) and the case where the pattern 714 has different specifications (Sampling Opt.1-3) ) Was simulated by simulating changes in the amount of water adsorbed over time in the state of being immersed in water. It means that the time increases from the lower part to the upper part and the moisture decreases as the color changes from red to blue.

Referring to the drawing, the amount of water adsorbed per unit time is 6.2050e -6 kg when there is no pattern 714 on the disk 71. The amount of water adsorbed immediately after immersing the disk 71 is not so large, It can be seen that it is maintained for a long time.

The pattern 714 of the disk 71 is formed such that the depth of the groove 715 is 0.1 mm and the length of one side of the projection 716 is 1 mm and the distance between the vertexes of the adjacent projections 716 The amount of water adsorbed per unit time is 9.7493e -6 kg and the adsorption holding time of the water is the shortest except for the case where the pattern 714 is absent, The least is known.

The pattern 714 of the disk 71 is formed such that the depth of the groove 715 is 0.15 mm and the length of one side of the protrusion 716 is 0.5 mm and the vertex of the adjacent protrusion 716 It can be seen that the amount of water adsorbed per unit time is 1.2679e -5 kg.

The pattern 714 of the disk 71 is formed such that the depth of the groove 715 is 0.15 mm and the length of one side of the protrusion 716 is 0.5 mm and the vertex of the adjacent protrusion 716 The amount of water adsorbed per unit time is 1.6498e- 5 kg, and the adsorption holding time of water is the longest, and the amount of water adsorbed is also the largest.

The amount of adsorption of moisture is not unconditionally large because the depth of the groove 715 is unconditionally large and the adsorption amount of moisture through the combination of the length of one side of the projection 716 and the distance between the vertexes at the depth of the same groove 715 You can see the most specific numbers.

Hereinafter, the operation of the humidifier according to the embodiment of the present invention will be described.

7 is a view showing an air flow state of the humidifier.

As shown in the figure, when the operation of the humidifier 1 is started, the fan 42 is rotated by the operation of the fan motor 210 and the disk 71 is rotated by the operation of the disk motor 351, Is rotated.

7, the disk 71 is rotated in the clockwise direction. When the disk 71 is rotated, the disk 71 wetted with water is exposed to the outside of the tray 21.

A portion of the disk 71 is immersed in the water while the disk 71 is filled with water and the area of the disk 71 contained in the water as the disk 71 rotates is exposed to the outside of the water And the area of the disk 71 in the exposed state is repeatedly immersed in water.

The disk 71 is in a state in which water is adsorbed on both sides by the pattern 714 formed on the disk 71 in the process of being immersed in water. At this time, since the pattern 714 is formed by grooves arranged in a lattice shape on the entire surface of the disk 71, moisture moves along the grooves, and therefore, the pattern 714 can be uniformly adsorbed to the entire portion of the water.

When the fan (42) is rotated, air is sucked into the humidifier (1) through the first suction port (104) and the second suction port (102). That is, air is sucked through the base 20, and air is sucked through the housing 10.

The air sucked through the first suction port 104 is lifted upward and flows through the space between the left and right sides of the disks 71 (as viewed in FIG. 5) It will contain moisture in the process of contact.

The air sucked through the second suction port 102 is allowed to flow through the disk assembly 70 at a high flow rate by the air guide 34 after passing through the filter on the suction grill 101 .

Accordingly, the entire upper surface of the disc 71 that can be brought into contact with the air can be brought into contact with the air to be sucked. In addition, water is contained in the space between the disks 71 while being in contact with the disk 71.

The humidified air is filtered while passing through the filter assembly 36 and is guided and raised by the upper case 31 of the case assembly 30 after passing through the fan 42.

The humidified air passes through the fan 42 and moves along the inner surface of the upper case 31 and the decor member 11 and then is discharged from the humidifier 1 through the discharge opening 103. At this time, since the discharge port 103 has a closed loop shape, the discharge direction of the humidified air becomes 360 degrees, so that the humidified air can spread evenly in the room.

Meanwhile, the disk 71 according to the embodiment of the present invention is formed by injection molding using a metal mold. In order to form a pattern 714 formed on the surface of the disk 71, the metal mold is etched . Therefore, the disk 71 can be mass-produced at a low cost and can be produced promptly because no additional post-processing is required.

The shape of the pattern 714 formed on the disk 71 may be very precise depending on the precision of the mold, and the shape of the pattern 714 may not be clear.

However, if the pattern 714 is unclear, the adsorption performance of the water will be much better than that of a general patterned disc if it has a lattice structure as a whole and has a shape approximate to that of the protrusions 716 and the grooves 715, Embodiments of the present invention are defined to include such a pattern.

Hereinafter, another embodiment of the present invention in which the overall pattern of the disk 71 has a lattice shape will be described.

8 is an enlarged perspective view of a surface of the disk according to another embodiment of the present invention.

As shown in the figure, on the surface of the disk 81 according to another embodiment of the present invention, a lattice-like groove 815 and a pattern 814 made of a projection 816 are formed. That is, a grating-like groove 815 extending in an oblique direction is formed on the surface of the disk 81, and these grooves 815 are all connected to each other.

Of course, the shape of the protrusion 816 is not uniform, but it is seen that the protrusion 816 has a rhombus shape as a whole. Therefore, it can be understood that the adsorbent of the present invention can have the same adsorption capacity as that of the embodiment of the present invention.

9 is an enlarged perspective view of a surface of the disk according to another embodiment of the present invention.

As shown in the figure, on the surface of the disk 91 according to another embodiment of the present invention, a plurality of grooves 915 extending in a lattice form and a projection 916 formed by the grooves 915 A pattern 914 is formed. That is, it can be seen that a plurality of tilted lattice-like grooves 915 are formed on the surface of the disk 91, which is represented by black.

At this time, the grooves 915 are not formed in a straight line shape but are formed of a set of grooves 915 extending in an oblique direction as viewed from the whole, and are arranged in a direction intersecting with each other. Then, the projections 916 are formed by these grooves 915. Although the projections 916 are not rhombic in their circumferential shape, the region defined by the grooves 915 as a whole may be the same as a rhombus.

The pattern 914 may be said to be similar to the shape of the woven fabric depending on the expression system, but since the woven fabric also has the same structure as the lattice shape, only the expression system is changed for the same structure, It can be said to have. Thus, it can be seen that the same adsorption performance as in the embodiment of the present invention can be obtained

The pattern 914 of the disk 91 according to another embodiment of the present invention does not have a sharp and plain shape as a whole, but this is due to the difference in the selected machining accuracy during the injection molding of the disk 91, 91 is not precisely etched but satisfies the improvement of required adsorption performance.
