On the other hand, the water tank 140 is a member for receiving water. The water tank 140 may be positioned to be spaced apart from the rear surface of the air cleaning filter 130 in the housing 110 and positioned below the blower fan 120. The humidification filter 150 is immersed in the water tank 140.

Hereinafter, the humidification filter 150 according to an embodiment of the present invention will be described with reference to FIGS. 2 to 6.

Figure 2 is a schematic exploded perspective view of the humidification filter according to an embodiment of the present invention, Figure 3 is a combined perspective view. 4 is a cross-sectional view taken along the line A-A of FIG. 3, and is a cross-sectional view of the humidifying filter of a portion where the support is not located. FIG. 5 is a cross-sectional view taken along line B-B of FIG. 3, and is a cross-sectional view of the humidifying filter at a portion where the support is located. On the other hand, Figure 6 is a cross-sectional view of the support according to an embodiment of the present invention.

As shown in Figure 2 and 3, the humidification filter 150 according to an embodiment of the present invention is the frame 152, the first humidification filter 154, the second humidification filter 156 and the support 155, 157). Humidification filter 150 according to an embodiment of the present invention is preferably a double humidification filter consisting of the first humidification filter 154 and the second humidification filter 156.

First, the frame 152 is a member that fixes and supports the first humidification filter 154 and the second humidification filter 156. In the present embodiment, the frame 152 preferably has a rectangular cross section having a width W ₃ greater than the widths W ₁ and W ₂ of the first humidification filter 154 and the second humidification filter 156. . In more detail, the frame 152 has a rectangular cross section, and preferably has a tetrahedral shape in which an inner space 153 into which the first humidification filter 154 and the second humidification filter 156 are inserted is formed. On the other hand, the inner space 153 also preferably has a rectangular space open to correspond to the shape of the frame 152.

2 to 5, the first humidification filter 154 has a pleated pleated shape to increase the surface area where water is absorbed. In addition, the first humidification filter 154 is formed with a plurality of small openings 154a arranged in a line along the height direction H in order to improve water absorption and air permeability. Preferably, the plurality of small openings 154a are formed over the entire first humidification filter 154.

The first humidification filter 154 having a pleated shape has a width W _{1 that} is narrower than the width W _{3 of the} frame 152, and has the same height H and length L as the frame 152. It is preferable that it is a rectangular parallelepiped shape. Accordingly, when the first humidification filter 154 is fixed to the inner surface of the frame 152, a part of the inner space 153 of the frame 152 is set aside. At this time, the internal space 153 is closed by the first humidification filter 154 in an open state.

On the other hand, when the volume of the first humidification filter 154 inserted into and fixed to the frame 152 is constant, the surface area of the first humidification filter 154 is increased as the gap between the wrinkles and the wrinkles is narrower. However, as the first humidification filter 154 has a narrower gap between the wrinkles and the wrinkles, when the water is immersed in the water tank and the water is absorbed, adjacent pleats may stick to each other to perform a function as a humidification filter.

To prevent this, the first humidification filter 154 is provided with one or more supports to maintain the gap between the pleats and the pleats. However, in the present exemplary embodiment, the support for fixing the first humidification filter 154 will be referred to as a first support 155 for convenience of description.

The first support part 155 is a member for maintaining the pleat shape of the first humidification filter 154, that is, the gap between the pleats and the pleats forming the pleat shape, as shown in FIGS. 2 and 3. It is preferable that a plurality is provided at the front side and / or the rear side of the first humidification filter 154 along the longitudinal direction L of the side 154.

As shown in FIG. 5, the first support part 155 is formed by filling and curing silicon between wrinkles and wrinkles. Alternatively, as shown in FIG. 6, the first support part 155 may be a structure having a square cross section which can be inserted and fixed between the pleats to maintain the spacing therebetween.

On the other hand, as shown in Figure 2, the second humidification filter 156 is inserted into the remaining space of the inner space is detachably mounted to the frame 152. Preferably, when the second humidification filter 156 is installed in the housing 110, the front side of the second humidifying filter 156 is positioned to be spaced apart from the rear side of the air cleaning filter 130, that is, the front side of the air humidifying filter 130. It is preferable to be inserted into and fixed to the frame 152 so as to contact the front surface of the filter 154.

Like the first humidification filter 154, the second humidification filter 156 preferably has the same length L and height H as the frame 152, but is not limited thereto. However, in the present embodiment, the width W ₂ of the second humidification filter 156 is preferably narrower than the width W ₁ of the first humidification filter 154.

Specifically, it is preferable that the ratio of the width of the first humidification filter 154 and the second humidification filter 156 is (W ₁ : W ₂ ) 6: 1 to 3: 1. When the width ratio is (W ₁ : W ₂ ) is 6: 1 to 3: 1, the second humidification filter 156 is narrow in width (W ₂ ) while maintaining the pleat shape, so that the internal blockage due to the scale occurs. Because this is less. In addition, even if the second humidification filter 156 has a width W ₂ smaller than the width W ₁ of the first humidification filter even though the scale is blocked due to the internal scale, the scale existing inside the water is washed with water. Easily melts and scales can be easily removed.

2 to 5, the second humidification filter 156 preferably has a pleated pleated shape like the first humidification filter 154 to increase the surface area where water is absorbed. In addition, the second humidification filter 156 is formed with a plurality of small openings 156a arranged in a line along the height direction H in order to increase water absorption and improve breathability. Preferably, the plurality of small openings 156a are formed over the second humidification filter 156.

On the other hand, the second humidification filter 156, like the first humidification filter 154 is provided with at least one support for maintaining the gap between the wrinkles and wrinkles. In the present embodiment, a support for fixing the second humidification filter 156 will be referred to as a second support 157 for convenience of description.

As shown in FIG. 2 and FIG. 3, a plurality of second support parts 157 may be provided at the front and / or rear surfaces of the second humidification filter 156 along the length direction L of the second humidification filter 156. It is desirable to be. As shown in FIG. 6, the second support part 157 preferably has the same shape as the first support part 155. In addition, the second support part 157 preferably has the same function as the first support part 155.

According to one embodiment of the present invention, only the second humidification filter 156 having a removable structure with the frame 152 is separated and periodically cleaned to remove scale, scale, etc. generated in the second humidification filter 156. As a result, the service life of the humidification filter 150 is extended by slowing the closing speed of the first humidification filter 154.

Hereinafter, referring to Table 1, the materials of the first and second humidification filters 154 and 156 for increasing the amount of humidification will be described. Table 1 is a performance comparison table comparing the absorption rate and daily humidification amount per unit time between materials based on cellulose. The numerical values shown in Table 1 are results of absorption per unit time and daily humidification amount based on cellulose when only the materials of the first and second humidification filters 154 and 156 are different under the same conditions.

In this embodiment, the material of the first and second humidification filters 154 and 156 is preferably a synthetic resin containing 60% to 80% rayon and 20% to 40% polyethylene terephthalate (PET). This will be described with reference to Table 1 below.

material Absorption rate per unit time (%) Daily Humidity (%) Cellulose 100 100 Rayon (containing 60% to 80%) +
PET (containing 20% to 40%) 100 100 PET 60 40 PP 30 20

Through Table 1, the first and second humidification filters 154 and 156 contain 60% or more of cellulose or rayon, so that the more hydrophilic material is polyethylene terephthalate (hereinafter referred to as 'PET') or Compared with synthetic resins such as polypropylene (hereinafter referred to as 'PP'), it can be seen that the absorption rate and daily humidification amount per unit time are significantly higher.

For example, when the first and second humidification filters 154 and 156 are made of only cellulose, the first and second humidification filters 154 and 156 may achieve 100% water absorption per unit time and daily humidification amount. have. However, cellulose is difficult to maintain the pleated shapes of the first and second humidification filters 154 and 156 for a long time, so that replacement cycles are frequent. In addition, there is a problem in that the replacement cost of the humidification filter 150 is increased.

On the other hand, when the first and second humidification filters 154 and 156 are made of only PET or PP, which is a synthetic resin, the material is harder than cellulose, so it is easy to maintain a pleat shape, as shown in Table 1 above. Absorption rate and daily humidification amount per unit time are significantly reduced.

In detail, PET has a 40% reduction in water absorption per unit time compared to cellulose and a 60% reduction in daily humidification. In addition, PP has a 70% reduction in absorption per unit time compared to cellulose, and a daily humidification amount is also reduced by 80%. This is because the synthetic resin PP or PET has a weaker force to attract hydrogen (H) of water molecules (H ₂ O) than cellulose. Therefore, when the first and second humidification filters 154 and 156 are made of only synthetic resin, it is easy to maintain the pleat shape, but unlike cellulose, there is a problem in that water absorption rate and daily humidification amount that absorb water per unit time are low.

Accordingly, in the present embodiment, the first and second humidification filters 154 and 156 contain rayon within a range of 60% to 80% to maintain the absorption rate per unit time and the daily humidification amount close to cellulose. In order to maintain the pleat shape, it is preferable that the material contains PET in the range of 20% to 40%. This is because when the rayon content is less than 60% of the material of the first and second humidification filters and the PET content is more than 40% of the material, it is easy to maintain the pleat shape, but the water absorption is not excellent. In the present embodiment, the reason why rayon is used instead of cellulose as the hydrophilic material is that rayon is similar to natural cellulose due to its similar material and structure as natural cellulose as synthetic cellulose. Because it is cheap.

Hereinafter, the flow of air during operation of the blower fan 120 will be described with reference to FIG. 1.

In the present embodiment, as the blower fan 120 is a bidirectional suction fan, when the blower fan 120 is operated, external air flows into the housing 110 through the inlet 111 along the arrow direction F1, After filtered by the air cleaning filter 130, the suction is sucked into the front of the blowing fan 120 and exits through the upper portion of the blowing fan 120, it is discharged to the outside through the discharge port 112.

Alternatively, the air introduced into the housing 110 during the operation of the blower fan 120 sequentially moves the air cleaning filter 130, the second humidification filter 156, and the first humidification filter 154 along the arrow direction F2. In the humidified state while passing sequentially, the suction is sucked into the rear surface of the blowing fan 120 and exits through the upper portion of the blowing fan 120, and then is discharged to the outside through the discharge port 112.

As the above process is repeated, scales are pinched in the first and second humidification filters 154 and 156, and the scale causes clogging in the humidification filter. In particular, the second humidification filter 156 positioned adjacent to the air cleaning filter 130 comes into contact with the filtered air first, so that the scale is pinched more than the first humidification filter 154. However, the second humidification filter 156 has a structure detachable from the frame 152, so that only the second humidification filter 156 may be separated from the frame 152, washed, and reused, and the humidification filter 150 may be reused. The service life of the can be extended.

The exemplary embodiments described above are intended to be illustrative, not limiting, in all aspects of the invention. Accordingly, the present invention is capable of many modifications and detailed implementations which may be obtained from those contained within the specification by those skilled in the art. All such modifications and variations are to be considered as within the scope and spirit of the invention as defined by the following claims.
