Description

Filter device for water purifier {FILTER APPARATUS FOR WATER PURIFIER}

The present invention relates to a filter device for a water purifier, and more particularly, to a filter device for a water purifier that can simplify the filter structure of the water purifier by performing a complex or multiple steps of filtering processes for the purified water in one filter. It is about.

Currently, water purifiers installed in homes, commercial offices, offices, etc. have the basic function of filtering purified water such as tap water or natural water, and providing them as purified water of hot or cold water (room water). A number of filtering processes are designed to remove harmful ingredients to the human body, as well as to deodorize and sterilize bacteria that cause water-borne diseases.

In other words, in the water purifier, a pre-carbon filter and a membrane surface having a filtering function by adsorption by fine pores of the activated carbon filter material and a sediment filter formed of purified water as the purified water passes sequentially. UV hollow fiber membrane filter, post-carbon filter and UV sterilization filter by UV hollow fiber membrane filter material to remove contaminants through a number of micropores distributed in It is optionally applied to perform the filtering process.

In case of precipitating filter, pretreatment-carbon filter and post-treatment-carbon filter used in water purifier, filter material (for example, pretreatment-carbon filter, filter case containing activated carbon filter material is stored in the outer case. In general, a structure in which the purified water obtained through the inlet communicated with is filtered by the filter material in the filter case and then exited through the outlet of the outer case.

However, in the water purifier, since the sedimentation filter, pretreatment-carbon filter, UV hollow fiber membrane filter, post-treatment-carbon filter, and UV sterilization filter, which form a plurality of filtering stages, are separately formed, the structure of the water purifier is complicated, and each filter is continued. Connection hoses or connecting members for connection to the consumption is not a lot.

In addition, since the filters applied to the water purifier need to be replaced every predetermined cycle to maintain the best function, it is cumbersome to replace the filter at the appropriate time when a plurality of filters are employed.

Accordingly, the present invention has been made in view of the above-described prior art, and provides a filter device for a water purifier in which a plurality of filter materials are accommodated in one filter case so that a plurality of filtering processes are continuously executed in the filter case. Has its purpose.

In order to achieve the above object, according to a preferred embodiment of the present invention, in the filter device for a water purifier comprising a filter case filled with activated carbon filter material therein, any one of the upper side and the inner side of the first filter portion of the activated carbon filter material A second filter portion of the UV hollow fiber membrane filter material is disposed, and a filter device for a water purifier provided with a separation plate between the first and second filter portions.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

A separation plate 50C made of, for example, a nonwoven fabric is disposed between the filter portions 50B.

Here, it is preferable that the first filter part 50A is filled with an activated carbon filter material and the second filter part 50B is filled with a UV hollow fiber filter material.

In addition, at one end of the filter case 50, a protrusion 52 is formed to maintain a constant gap when the filter case 50 is placed in an outer case (see '10' in FIG. 1), and an integer around the protrusion 52 is formed. An inlet 54 is formed through which the target water flows.

A first filter material leakage preventing member 56 is disposed on the bottom surface of the filter case 50 in which the water inlet 54 is formed to prevent the activated carbon filter material filled in the first filter part 50A from leaking. The filter material leakage preventing member 56 is preferably formed of a nonwoven fabric, a sponge, or a urethane resin foam to facilitate passage of purified water.

In addition, an upper end of the filter case 50 is formed with an annular order projection 60 (see the order projection 22 in FIG. 1), and the first and second filter portions are formed inside the order projection 60. A water exit hole 62 through which the filtered purified water is discharged is formed while passing through 50A and 50B.

In addition, the filter material (that is, UV hollow fiber filter material) filled in the second filter part 50B also does not leak out of the filter case 50 to the upper side of the second filter part 50B. The second filter material leakage preventing member 64 is provided to the bar, and the second filter material leakage preventing member 64 is also formed of the same material as the first filter material leakage preventing member 56.

Therefore, when the corresponding filter case 50 is disposed in the outer case (see '10' in FIG. 1), the purified water flowing into the outer case may be obtained through a water hole formed at the bottom of the filter case 50 ( 54 obtained through the first filter material leakage preventing member 56, the first filter part 50A, the separation plate 50C, the second filter part 50B, and the second filter material leakage preventing member 64. ), And the filtered integer is transmitted to the outlet (see '12b' in FIG. 1) through the outlet 62.

That is, in the filter device for water purifier shown in FIG. 1, the multi-stage filtering is performed by the first filter part 50A and the second filter part 50B in which the purified water is disposed in one filter case 50. When the first filter part 50A is formed of an activated carbon filter material and the second filter part 50B is formed of a UV hollow fiber membrane filter material, for example, the pretreatment-carbon filter and the UV hollow fiber membrane filter may be unified. do.

2 is a view showing a modification of the filter device for a water purifier according to the second embodiment of the present invention shown in FIG.

That is, according to the present modification, the first filter part 50A and the second filter part 50B are arranged in the shape shown in FIG. 2, and the first filter part is formed inside the filter case 50. The 50A is formed by receiving activated carbon inside the first filter part case formed in a cylindrical shape by, for example, a nonwoven fabric, and the second filter part 50A is stored inside the hollow of the first filter part case, for example, on a nonwoven fabric. By the UV hollow fiber membrane filter material is filled in the second filter portion case formed in a cylindrical shape, the hollow inside of the second filter portion case is provided as a water purification path.

In addition, a lower cap member S is provided at a lower end of the second filter part case to prevent the inflow of the UV hollow fiber membrane filter material while preventing the inflow of purified water that has not passed through the first filter part 50A. It is coupled, the filter support 70 for supporting the corresponding second filter unit 50B is located on the lower side, the filter support 70 is the second filter unit 50B is the filter case 50 If it is installed to abut the bottom surface is not necessarily required.

Similarly, an upper cap member 74 is formed at an upper end of the second filter case, and a purified water appearing inside the hollow of the second filter part case is delivered to the outlet side at a central portion of the upper cap member 74. A water extraction hole 76 is formed to be formed, and a 0-ring 78 is disposed at an outer circumference of the upper cap member 74 to prevent leakage of the water discharged water.

Therefore, when the corresponding filter case 50 is disposed in the outer case, the purified water flowing into the outside of the filter case 50 is formed at the lower end thereof, and is introduced through the inlet 54 so that the first filter part 50A is provided. And is filtered while passing through the second filter unit 50B, and the filtered integer is transmitted to the outlet port (see '12b' in FIG. 1) through the outlet hole 76.

Therefore, even in the present modification, when the first filter part 50A designed in the single filter case 50 is formed of the activated carbon member and the second filter part 50B is formed of the UV hollow fiber membrane filter material, Multilevel filtering is possible.

On the other hand, the present invention is not limited to the above-described application example, it is a matter of course that various changes and modifications can be carried out within the scope not departing from the technical gist and point of the invention. That is, in the above description, it is assumed that the first filter portion is formed of the activated carbon filter material and the second filter portion is formed of the UV hollow fiber membrane filter material, but it is not necessarily limited to the application example of such a filter material, and the arrangement structure thereof is also not limited. It is not limited to the application example.

In addition, the case of the second filter part made of a nonwoven fabric provided in the filter case is further advantageously coated with nano-siver to have sterilization or antibacterial properties against bacteria and bacteria.

In addition, the case of the second filter part may be manufactured by foaming only the upper side by foaming urethane resin, and during the foaming of the urethane resin, rice husk charcoal and / or nanosilver, jadeite / marble / germanium / ocher It is advantageous to add fine powders such as these selectively or in combination.

In addition, in the above description, only the state in which the present invention is applied to the filter case of the structure in which the purified water flows in one direction has been described, but it is of course applicable to the bidirectional filter case in which the purified water flows from one side and drained from the other side. .

As described above, according to the filter device for a water purifier according to the present invention, the filtering performance in the water purifier is deteriorated by designing the first and second filter parts in a single filter case so that the filtering is performed in multiple stages for the purified water. It is possible to reduce the number of filter cases without doing so.

That is, in one filter case, when the first filter part is filled with activated carbon filter material and the second filter part is filled with UV hollow fiber membrane filter material, a complex filtering process is performed on the purified water. Filter performance in the water purifier is not only reduced, but the number of filters in the water purifier is also reduced, and the number of filter cases that must be discarded is also advantageous when the filter is replaced. It can be greatly reduced.
