The filtering unit 300 may be provided inside the filter housing 200, that is, inside the housing body 220 of the filter housing 200 as shown in FIGS.

1 and 3, the filtration unit 300 may include a plurality of carbon particles 310 activated to filter water. The plurality of carbon particles 310 may be activated carbon, for example. However, the plurality of carbon particles 310 is not limited to activated carbon, and any well-known carbon particles 310 can be used as long as they are capable of filtering water. The plurality of carbon particles 310 may be provided under the housing main body 220 of the filter housing 200 by self weight as in the illustrated embodiment.

9, the plurality of carbon particles 310 are introduced into the filter housing 200 through the inlet I and the inlet passage 211 of the dual tube 210, that is, the housing main body 220 of the filter housing 200 The water can be floated by the inflow water. As described above, the plurality of carbon particles 310 floated by the introduced water can be attached to the filter member 320, which will be described later. Then, water may be filtered while passing through the plurality of carbon particles 310 attached to the filter member 320 and the filter member 320.

The filtration unit 300 may include a filter member 320 as in the embodiment shown in FIGS. The filter member 320 may also be provided within the interior of the filter housing 200, that is, inside the housing body 220 of the filter housing 200, as shown in the illustrated embodiment. By the filter member 320, the carbon particles 310 can be prevented from flowing out to the outside.

For this purpose, the filter member 320 may be formed of at least two layers such that a space sealed to the outside is formed therein, as in the embodiment shown in FIG. Also, the dual tube 210 may be positioned through the filter member 320, as in the embodiment shown in FIG. Further, the filter member 320 may be attached to the double tube 210 in a sealed manner, for example, by ultrasonic welding.

In this case, That is, the water introduced into the inner space of the filter member 320 through the filter member 320 passes through the first connection hole 212a of the double pipe 210, ). ≪ / RTI >

On the other hand, the filter member 320 may be wound on the double tube 210 more than once as in the embodiment shown in FIG. As described above, when the filter member 320 is wound on the double tube 210 more than once, more filter members 320 can be provided on the housing body 220 of the filter housing 200. Accordingly, a larger amount of water can be passed through the filter member 320 to which the carbon particles 310 adhere, so that the filtration efficiency of the water can be improved.

5 to 8, the filter member 320 may be bent and folded a plurality of times. When the filter member 320 is bent and folded a plurality of times, the contact area between the filter member 320 and the water can be increased. Therefore, the filtration efficiency of water can be improved.

The filter member 320 may include a first filtration layer (not shown) and a second filtration layer (not shown).

The first filtration layer may be formed with a plurality of holes having a size of 1 mu m to 2 mu m. Accordingly, when water passes through the first filtration layer, particulate matter such as fine particles of carbon particles 310 contained in water and some bacteria may be filtered.

If the pore size formed in the first filtration layer is less than 1 mu m, particulate matter and some bacteria smaller than 1 mu m are also filtered by the first filtration layer and accumulated in the first filtration layer. As a result, a relatively large amount of particulate matter and bacteria accumulate in the first filtration layer, so that at least a part of the first filtration layer can be clog early. In this way, the filtration efficiency of the first filtration layer is lowered and the service life can be reduced.

If the pore size formed in the first filtration layer is larger than 2 mu m, the particulate matter and the bacterium of 2 mu m or more can not be filtered by the first filtration layer. Therefore, the particulate matter and bacteria to be filtered in the second filtration layer . Thereby, a relatively large amount of particulate matter and bacteria accumulate in a part of the second filtration layer, so that at least a part of the second filtration layer can be clog early. Further, the filtration efficiency of the second filtration layer is lowered and the service life can be reduced.

Therefore, it is preferable that the size of the hole of the first filtration layer, in which at least a part of the first filtration layer and the second filtration layer are not clogged early, the filtration efficiency is not lowered, and the service life is not reduced, is preferably 1 탆 to 2 탆.

The second filtration layer may be located next to the first filtration layer in the direction of flow of water. Thus, the filtered water passing through the first filtration layer can be filtered while passing through the second filtration layer. A plurality of holes having a size of 0.02 mu m to 1 mu m may be formed in such a second filtering layer. Thus, bacteria and some particulate matter can be filtered.

If the pore size formed in the second filtration layer is less than 0.02 탆, water may not pass through because the pore size is too small. Even if a small amount of bacteria and some particulate matter contained in water accumulate in the second filtration layer even if the filtration passes, at least a part of the second filtration layer is clogged early. Thereby, the filtration efficiency of the second filtration layer is lowered and the service life can be reduced.

Also, if the pore size of the second filtration layer is larger than 1 mu m, particulate matter and bacteria smaller than 1 mu m can not be filtered. Therefore, fine particles and bacteria can not be filtered.

Therefore, the pore size of the second filtration layer, which is capable of filtering at least a part of the second filtration layer and the fine size particulate matter and bacteria without deteriorating the filtration efficiency and not shortening the lifetime, is in the range of 0.02 탆 to 1 탆 .

The filter member 320 may further include a third filtration layer (not shown). The third filtration layer may be located after the second filtration layer in the direction of flow of water. The third filtration layer may have a plurality of holes larger than the plurality of holes formed in the first filtration layer and the second filtration layer. To this end, the third filtration layer may be, for example, in the form of a mesh. As a result of the third filtration layer, the filtered water flows smoothly through the first filter layer and the second filter layer and flows into the inner space of the filter member 320, And can be introduced into the outflow passage 212 of the double pipe 210 through the connection hole 212a.

Meanwhile, the filter member 320 may be formed of a nonwoven fabric, that is, one or more nonwoven fabrics. Thus, when the filter member 320 is made of the nonwoven fabric composite, water flows through the filter member 320 in a zigzag manner, so that the flow distance becomes long. As a result, the contact area with water is increased, so that the filtration efficiency for filtering particulate matter or bacteria contained in water can be improved.

However, the filter member 320 may be formed of a fiber membrane or a synthetic resin membrane in addition to the above-described nonwoven fabric composite, or a combination of a nonwoven fabric composite and a fibrous membrane or a combination of a nonwoven fabric composite and a synthetic resin membrane.

As described above, when the carbon filter according to the present invention is used, the water flows into the lower part through the upper part, and when the water flows in, the carbon particles can easily float, and the carbon particles of comparatively low cost are used Water can be filtered, the filtration efficiency of the carbon filter can be improved, the life can be extended, and the production cost and production time of the carbon filter can be reduced.

The carbon filter described above is not limited to the configuration of the embodiment described above, but the embodiments may be configured by selectively combining all or some of the embodiments so that various modifications may be made.
