The housing 200 may be configured to allow the water to be filtered and the filtered water to be discharged as shown in FIG. To this end, the housing 200 may include a water inlet 221 through which the water to be filtered flows and a water outlet 231 through which the filtered water is discharged.

As shown in FIGS. 1 to 3, the housing 200 may include a housing body 210 and a housing cover 220.

The housing body 210 is opened at one side and a space may be formed in which a carbon filtration unit 300, a first filtration member 400 and a second filtration member 500 to be described later are provided. The housing cover 220 may cover one side of the housing body 210 that is open.

The housing cover 220 may be formed with an inlet 221 as shown in FIGS. A plurality of inlet ports 221 may be formed in the housing cover 220 as shown in FIG. Water to be filtered may be introduced into the interior of the housing 200 through the inlet 221 as shown in FIG.

Also, as shown in FIGS. 1 to 3, a through hole 222 may be formed in the housing cover 220. As shown in the figure, the through hole 222 is formed with a water outlet 231 of the upper support member 230 for supporting the upper portion of the first filtration member 400 and the second filtration member 500, Can be passed.

However, the shape of the housing body 210 and the shape of the housing cover 220 are not particularly limited, and one side may be opened, and the carbon filter unit 300, the first filter unit 400 and the second filter unit 500 And any shape can be used as long as the space is formed and can cover the open side of the housing body 210.

3, the outlet 231 of the upper support member 230 is positioned to pass through the through-hole 222 of the housing cover 220, so that the carbon filter unit 300 and the first filtration unit 300, which will be described later, The upper portion of the member 400 and the second filtration member 500 can be supported. The lower portion of the first filtration member 400 and the second filtration member 500 may be supported by the lower support member 240 as shown in FIG.

The carbon filtration unit 300 may include granular activated carbon. Thereby, the water introduced into the housing 200 can be filtered. That is, water can be filtered by collecting foreign matter contained in water in the pores formed in the granular activated carbon.

Therefore, foreign matter contained in water can be collected by each granular activated carbon, so that the filtration performance can be excellent. In addition, only a portion is not used for filtration, and all portions can be used for filtration.

The particulate activated carbon contained in the carbon filtration section 300 is not particularly limited, and any known particulate activated carbon can be used as long as it is granular activated carbon capable of filtering water.

The first filter member 400 can support the outer side of the carbon filter unit 300. For example, as shown in FIG. 2, if the carbon filtration part 300 is a hollow cylindrical shape, it can support the cylindrical outside.

Accordingly, the above-described granular activated carbon contained in the carbon filter portion 300 may not spread to portions of the housing 200 other than the carbon filter portion 300.

In addition, the first filtering member 400 may be configured to allow the water flowing into the housing 200 to pass therethrough and then flow to the carbon filter unit 300. That is, the water introduced into the housing 200 through the inlet 221 may be filtered while passing through the first filter member 400, and then filtered by the carbon filter unit 300.

To this end, the first filter element 400 may comprise a nonwoven fabric composite layer comprising charged fibers.

A large number of pores may be formed in the nonwoven fabric composite layer. Accordingly, foreign matter contained in the water, which is larger than the pore size formed in the nonwoven fabric composite layer, can not pass through the nonwoven fabric composite layer.

Thereby, the water can be filtered while passing through the first filter member 400 including the nonwoven fabric composite layer.

The size of the pores of the first filter member 400 may be 4 탆 to 6 탆.

If the pore size of the first filter member 400 is less than 4 탆, foreign matter filtered by the first filter member 400 may be relatively large. As a result, the first filter member 400 can be clogged early by the foreign substance, so that the service life can be shortened.

If the pore size of the first filter member 400 is larger than 6 mu m, foreign matter filtered by the first filter member 400 may be reduced. As a result, the foreign matter to be filtered by the carbon filter 300 and the foreign matter to be filtered by the second filter member 500 to be described later can be relatively increased. Therefore, the carbon filter unit 300 and the second filter member 500 can be clogged early by the foreign substance, so that the service life can be shortened.

As described above, the nonwoven fabric composite layer included in the first filter member 400 may include charged fibers. As a result, the microorganisms on the surface, such as viruses and bacteria that can not be filtered by pores, can be collected by the electrostatic force of the charged fibers because the size thereof is generally 0.02 to 0.5 μm.

The charged fibers can be charged glass fibers, electrified alumina fibers or electrified cellulose. However, it is not particularly limited and any known fiber may be used.

The first filter member 400 may be folded and folded a plurality of times as shown in FIGS. Accordingly, since the contact area between the first filter member 400 and the water can be widened, the filtration performance of the first filter member 400 can be improved.

The second filtration member 500 can support the inside of the carbon filtration part 300. For example, as shown in FIG. 2, if the carbon filter unit 300 is a hollow cylindrical member, the second filter member 500 may be inserted into the hollow member to support the inner hollow member.

Accordingly, the above-described granular activated carbon contained in the carbon filter portion 300 may not spread to portions of the housing 200 other than the carbon filter portion 300.

In addition, the second filtering member 500 can be filtered while passing the filtered water through the carbon filtering unit 300. That is, as shown in FIG. 3, the water filtered by the granular activated carbon in the carbon filter unit 300 can be filtered while passing through the second filter member 500. And may be discharged to the outside through the outlet 231 as shown.

To this end, the second filter element 500 may comprise a nonwoven fabric composite layer comprising charged fibers.

As described above, a large number of pores can be formed in the nonwoven fabric composite layer. Accordingly, foreign matter contained in the water, which is larger than the pore size formed in the nonwoven fabric composite layer, can not pass through the nonwoven fabric composite layer.

Thereby, the water can be filtered while passing through the second filter member 500 including the nonwoven fabric composite layer.

The size of the pores of the second filter member 500 may be 0.5 탆 to 1.5 탆.

If the pore size of the second filter member 500 is less than 0.5 탆, foreign matter filtered by the second filter member 500 may be relatively large. Thereby, the second filter member 500 can be clogged early by the foreign substance, so that the service life can be shortened.

If the size of the pores of the second filter member 500 is larger than 1.5 μm, the granular activated carbon contained in the carbon filter unit 300 may spread to other parts of the housing 200 through the pores of the second filter member 500 .

Therefore, the size of the pores of the second filter member 500 is preferably 0.5 탆 to 1.5 탆.

As described above, the nonwoven fabric composite layer included in the second filter member 500 may include charged fibers. As a result, the microorganisms on the surface, such as viruses and bacteria that can not be filtered by pores, can be collected by the electrostatic force of the charged fibers because the size thereof is generally 0.02 to 0.5 μm.

The charged fibers can be charged glass fibers, electrified alumina fibers or electrified cellulose. However, it is not particularly limited and any known fiber may be used.

The second filtration member 500 may also be folded a plurality of times as shown in FIGS. Accordingly, the contact area between the second filtration member 500 and the water can be widened, so that the filtration performance of the second filtration member 500 can be improved.
