Description

A complex filter for water purifier

The present invention relates to a composite filter, and more particularly, to a composite filter for purifying raw water containing two or more kinds of materials in a single water filter constituting a water purifier.

Recently, as the distrust of tap water due to environmental pollution increases, the use amount of water purifier is gradually increasing. The water purifier is a device for filtering tap water or ground water (hereinafter referred to as "raw water" Foreign matter and harmful substances contained in the raw water can be removed by filtering the raw water.

In recent years, there has been a demand for a miniaturized, slimmer, and complex water purifier product due to the increasing trend of a family member and a small family member. Accordingly, the use of a composite filter in which at least two kinds of materials are formed in one water filter is increasing.

In the conventional composite filter for a water purifier shown in Fig. 1,

In addition, the second water filter (3) may contain a silver component so as to have antimicrobial properties.

The flow path switching guide (12)

The raw water inflow passage 4 may be formed at the center and the purified water discharge passage 5 may be formed at an edge with respect to the raw water inflow passage 4. [

The flow path switching guide 12 is provided with the purified water discharge passage 5 at the center thereof and the raw water inflow passage 4 is formed in a gap between the flow path switching guide 12 and the filter cap 1b, Can be formed.

Alternatively, the first water filter (2) may be a sediment filter or a carbon block filter. The second water filter (3) may be a ceramic filter or a sediment filter.

As shown in FIG. 3, the first water filter 2 may be a hollow fiber filter (UF filter), and the second water filter 3 may be a particulate carbon filter.

As shown in FIG. 4, the first water filter 2 may be a nano-seal filter, and the second water filter 3 may be a carbon block filter.

As shown in FIG. 5, the first water filter 2 may be a nanosilam filter (flat membrane filter), and the second water filter 3 may be a particulate carbon filter.

3 to 5, in the composite filter for a water purifier according to another embodiment of the present invention, the configuration excluding the first and second water filters (2, 3) The detailed description thereof will be omitted.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the use of a composite filter for a water purifier according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2, raw water such as tap water flows into the filter housing 1 through the raw water inflow passage 4 of the flow path switching guide 12. The raw water passing through the raw water inflow passage 4 is moved to the lower portion of the filter housing 1 along the gap between the filter housing 1 and the skirt portion 10.

That is, since the raw water moved to the lower part of the filter housing 1 flows through the opening of the lower end of the filter case 13, the first water filter 2 contained in the filter case 13 The foreign substance is filtered.

On the other hand, an integer subjected to the first-order water purification treatment by the first water filter (2) is moved toward the second water filter (3) through the upper end opening of the filter case (13). At this time, raw water, which is passed through the raw water inflow passage (4) and is moved toward the first water filter (2) by the O-ring (14) mounted on the close contact portion of the skirt portion (10) It is possible to prevent mutual mixing of the purified water purified by the first purified water filter 2 and purified water that has been treated to the second purified water filter 3 side.

As the lower holder 9 is hot-melted and sealed at the lower end of the second water filter 3, the water purified by the first water filter 2 is treated by the second water filter (3), it is possible to prevent the water mixed with the water purified through the first water filter (2) and the water purified by the second water filter (3) .

On the other hand, the primary purified water purified water that has passed through the first water filter 2 and is moved to the second water filter 3 side has a gap between the skirt portion 10 and the second water filter 3 As shown in Fig.

The first purified water purified water which is moved upward along the clearance is subjected to the second water purification treatment while being moved in the radial direction of the second water filter 3. That is, the second purified water purified by the second water filter is transferred to the purified water discharge passage 5 of the flow path switching guide 12 along the constant flow path 15 formed in the second water filter 3 .

At this time, since the upper end of the second water filter 3 is hot-melted and sealed inside the channel switching guide 12, the water is moved from the first water filter 2 to the second water filter 3 Treated with the first purified water purified water and the second purified water purified water treated by the second purified water filter 3 and then moved toward the purified water discharge passage 5 of the flow path switching guide 12 .

According to the above-described composite filter for a water purifier according to the embodiment of the present invention, the raw water inflow passage 4 for introducing raw water into the filter housing 1, the first and second water filters 2, 3 The flow path switching guide 12 consisting of the purified water discharge passage 5 for discharging the purified water purified by the first water filter 3 and the skirt portion 10 for wrapping and housing the second water filter 3, (By way of example, be injection molded).

Therefore, it is possible to reduce the number of parts constituting the composite filter to reduce the cost cost, reduce the number of work processes for assembling, and improve the production efficiency due to mass production.
