Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a filter unit used for a water purification device.

[Conventional technology]

Conventionally, as a filter unit of a water purification device, for example, as shown in Japanese Utility Model Laid-Open No. 60-58296, a combination of granular activated carbon or fibrous activated carbon to form a filtration adsorption layer, and recently, There are various shapes such as a type filled with hollow porous fibers, a type using granular activated carbon carrying silver thereon, and a cylindrical body formed of a sheet of activated carbon fibers.

[Problems to be solved by the invention]

Except for the filter unit that supports silver on the granular activated carbon, the so-called purification function of adsorbing and separating fine particles and odorous components in water is excellent, but bacteria such as Escherichia coli, cholera, Shigella that sometimes exist in water are excellent. There is a problem that there is no ability to sterilize species. In recent years, water has often accumulated in water storage tanks in apartment complexes and condominiums, as well as in water coolers and vending machines for several days, and regular cleaning has been performed due to the occurrence of dead animal dead bodies and scales. There is a problem that if required, neglecting the above will cause the bacteria to occur and harm the human body.

Therefore, sterilization performance is also required for water purifiers,
For this reason, a water purifier in which silver is carried on the above-mentioned activated carbon is used, but there is a drawback that it is very expensive and difficult to spread.

[Means for solving the problem]

The present invention has been made in view of the above-mentioned conventional problems. By forming a filter unit by filling an adsorbing substance between the outer layer and the outer layer of a silver-plated fiber-containing nonwoven cylindrical body, the filter unit is uniformly formed in the nonwoven fiber layer. The area of contact with silver, which has a bactericidal action, is increased by the silver-plated fiber dispersed in the silver, and it can function effectively. The amount of silver used is greatly reduced compared to conventional products, and the internal adsorbent And a filter unit from which organic substances and odorous components are removed.

[Action]

Due to the uniform dispersion of silver-plated fibers mixed in the non-woven fiber layer of the cylindrical body, the effective contact surface area between silver and water is increased,
Even when a relatively small amount of silver-plated fiber is used, a sterilizing function can be effectively performed, and the filter unit has a capability of removing and filtering fine particles, thereby providing a low-cost filter unit. In addition, due to the adsorbed substance filled inside the cylinder, organic substances and odorous components,
Adsorbs and decomposes khaki.

〔Example〕

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

 FIG. 1 shows an example of an embodiment of the present invention.
FIG. 2 is a perspective view of the unit, and FIG.
FIG. As shown in the drawing, the filter unit of the present invention
(1)Means that the outer layer (2) and the inner layer (3) are silver-plated fibers, for example.
Acrylic fiber, Nomex Fiber (meta-aramid)
Thickness of silver coated on the fiber surface by electroless plating
10% to 50% by weight of silver plated fiber of 3 to 40μ and thickness of 3 to 40μ
Chemical fibers such as rayon, acetate, acrylic, PA,
PET, PP, PE, PVC, PP-PE, PET-CoPET, low melting point copolymer
90% to 50% by weight of one or more types selected from mid fiber
And the web formed by mixing
Idle punch method, water needle punch or chemical
Circle with short fiber dry non-woven fabric bonded by Le Bond method etc.
It is constituted by forming a cylindrical body (4).

At the upper and lower ends of the cylindrical body of the outer layer (2) and the inner layer (3), a circular water-impermeable sealing member (6) having an opening (5) having a diameter substantially equal to that of the inner cylindrical body at the center is arranged. A concave groove (7) is provided on the side where the inner layer and the outer layer cylinders are fixed, and the outer layer and the inner layer cylinders are fitted and fixed integrally with an adhesive, and formed between the outer layer and the inner layer cylinders. The gap (8) is filled with one or more substances selected from activated carbon particles, geolite, silica, alumina, activated carbon fiber, etc. as an adsorbing substance (9) after the one sealing member (6) is fixed, The other seal member is fixed to constitute the filter unit for a water purifier of the present invention.

The water-impermeable seal member used in the above embodiment is selected from synthetic resins such as vinyl chloride, polypropylene, ABS, acryl, polycarbonate, styrene, melamine, and phenol.

In the unit filter of the present invention configured as described above, water introduced into the inside during use first contacts the silver-plated part when passing through the non-woven fabric containing silver-plated fiber of the inner layer (3) and is sterilized, and then the adsorbed substance (9) As a result, organic substances and odorous components are adsorbed and decomposed. In addition, even if bacteria are generated in the organic substances and the odorous components adsorbed during continuous use, it is sterilized by the silver-plated fibers of the outer layer (2) on the outflow side, so that clean and odor-free water can be supplied for a long time. it can.

[Effect of the invention]

According to the present invention, as described above, the effective contact surface area between silver and water is increased by a uniform dispersion structure of silver-plated fibers mixed in the non-woven fiber layer of the filter cylinder, and a relatively small amount of silver-plated fibers Even with the use amount of, a sterilizing action is effectively functioned, and the filter unit has the ability to remove and filter fine particles, thereby obtaining a low-cost filter unit. In addition, organic substances and odorous components are adsorbed and decomposed by the adsorbed substance filled in the cylindrical body, and even if bacteria are generated on the adsorbed substance, sterilization is performed again by passing through the outer layer, so that it is clean and odorous for a long time. This is a device having a practical effect, such as being able to supply water free of water.
