Description

Small water filter {WATER TREATMENT FILTER FOR A BEDET}

The present invention relates to a water filter, and more particularly, to a small water filter that can perform the filtering and sterilization at the same time.

Water supplied to each household or industry through the water supply contains undesirable components. Therefore, the water supplied through the tap water is filtered through a purified water filter, and the filtered purified water is usefully used in various fields of home or industry.

In fact, water filters used in homes are widely used in home appliances that handle water such as refrigerators and bidets, as well as water purifiers.

Generally, the water filter includes a housing and a filter module contained within the housing. The filter module inside the housing may be in the form of particles such as activated carbon, anthracite, or the like, or in the form of fibers such as filter cloth, felt, or sponge, or may be provided in a porous form, such as carbon or plastic. In addition, the filter module can be microfiltration, ultrafiltration, nanofiltration, reverse osmosis, gas separation and electrodialysis according to the pore size and separation principle. And the like.

Conventional water filters are used for separating specific particles in water, and do not perform any other function, one of which is sterilization. Since a conventional water filter does not include a sterilizing function, bacteria can grow inside the filter, and as a result, the water quality of the water passing through the filter is often worsened or smelled.

In order to solve this problem, there is a "silver foam filter", Republic of Korea Utility Model Registration No. 20-350392 (announced on May 13, 2004).

1 is an exploded perspective view for explaining a conventional silver foam filter.

Referring to FIG. 1, the silver foam filter may be connected to piping lines such as a water purifier, a bidet, and a fish tank to add sterilizing power to water supplied to the water purifier, a bidet, and the like. To this end, the silver foam filter includes a filter body 11 containing the silver foam 23 and connecting portions 12 and 13 connected to external lines. Inside the filter body 11, the silver foam 23 and the ring (21, 22) for fixing the silver foam, and the water supplied from the outside through the connection portion 12, 13 sterilization and deodorization while passing through the silver foam (23) It is configured to be.

In addition, the Republic of Korea Utility Model Registration No. 338544 (January 16, 2004) there is a "water purification system including a functional ceramic ball filter".

2 is a configuration diagram illustrating a conventional water purification system.

Referring to FIG. 2, the water introduced through the raw water supply pipe 20 first includes a sediment filter 1, a precarbon filter 2, a functional ceramic ball filter 3, a post carbon filter 4, and the like. Passes through the hollow fiber membrane filter (5).

The sediment filter 1 is a conventional filter which removes various insoluble substances (rust, solids, etc.) contained in raw water, and the precarbon filter 2 provided in the rear end of the sediment filter 1 is used in water. It acts to remove chlorine, various carcinogens, etc., and carbon block activated carbon 13 is provided therein.

After impurities are primarily filtered out by the sediment filter 1 and the precarbon filter 2, water passes through the functional ceramic ball filter 3. At this time, various properties and components beneficial to the human body are imparted.

The functional ceramic ball filter 3 is provided with five ceramic ball filters, specifically, the elvan ceramic ball filter 14a, the coral sand ceramic ball filter 14b, the calcium ceramic ball filter 14c, and the zeolite ceramic ball filter ( 14d) and Tourmaline ceramic ball filter 14e are arranged in layers, respectively.

First, the elvan ceramic ball filter 14a radiates far-infrared energy in abundance, thereby activating water to reduce clusters of water molecules (water molecule clusters). Elvan ceramic balls are composed of elvan as the main raw material, and the water molecule cluster of the water passing through becomes small, so that absorption in the human body is quick.

The coral sand ceramic ball filter 14b elutes various minerals such as calcium, sodium, potassium, and magnesium, and adjusts the mineral content in the water to maintain a mineral balance like natural mineral water to improve water taste. It consists of Coral Sand as the main raw material.

The calcium ceramic ball filter 14c functions to elute calcium or the like to adjust the pH of the water to make weak alkaline water suitable for the body. In other words, it can be called a pH-adjusted ceramic ball. It is mainly composed of coral sand, ganban stone, zeolite, gallbladder and the like.

The zeolite ceramic ball filter 14d is provided by attaching silver to a ball made of zeolite and meteorite. Therefore, silver ion (Ag ⁺ ) etc. elute continuously from the impregnated silver. The silver ions (Ag ⁺ ) is contained in the antibacterial component, suppresses the generation of microorganisms in the filter, and serves to remove various odor components.

Finally, the tourmaline ceramic ball filter 14e is composed of tourmaline, zeolite, and meteorite as the main raw materials, and generates a weak current to generate beneficial anions to the human body and radiate far infrared rays to give the human body beneficial energy. Perform the function.

Since silver is impregnated on the surface of the double zeolite ceramic ball filter 14d, the water passing therethrough has bactericidal power, and microorganisms can be prevented from occurring inside the filter. However, silver adhering to the surface may be separated from the zeolite ceramic ball filter 14d in the form of fine dust, and the separated fine dust may form a hollow fiber membrane filter having a pore of about 0.01 to 0.3 μm. It may not pass and may remain on the surface.

In fact, fine dust made of silver remains on the surface of the ultrafiltration, thereby reducing the flow rate of the filter and shortening the life of the filter.

In addition, as shown in FIG. 2, the conventional water filter includes a sediment filter (1), a precarbon filter (2), a functional ceramic ball filter (3), a post carbon filter (4), and a hollow fiber membrane filter. (5), these filters are each mounted in different housings and connected to mutual hoses. It is difficult to miniaturize such a configuration, and there is a problem that its use is limited in refrigerators, bidets, and fish tanks that require the use of a small water filter.

As to overcome the above-mentioned problems of the present invention, one object of the present invention is to provide a small water purification filter that can impart sterilizing power to water and maintain a large flow rate and long life.

Another object of the present invention is to provide a small water filter having a structure in which the filter module and the antimicrobial substance are effectively disposed in a small size housing.

Still another object of the present invention is to provide a small water filter that can be applied to various home appliances having a mutual position and structure of the inlet and the outlet.
