The present invention relates to a composite filter assembly for a water purifier, and more particularly, to a composite filter assembly for a water purifier, whereby the composite filter assembly becomes more convenient by allowing the activated carbon filter unit and the hollow fiber membrane filter unit constituting the composite filter to be mutually coupled.

In general, a water purifier installed in a home or office has a basic function of filtering purified water required for purified water, such as tap water or natural water, as purified water of hot or cold water, and the water purifier includes suspended solids mixed in raw water. Therefore, a number of filtering processes are required to remove odors and sterilize bacteria that cause waterborne diseases.

The water purifier removes contaminants through a settling filter formed by purified water as the purified water passes sequentially, an activated carbon filter having a filtering function by adsorption by activated micropores, and a plurality of fine pores distributed on the membrane surface. A hollow fiber membrane filter (UF filter), an ultraviolet sterilization filter (UV filter), and the like are selectively applied to perform a plurality of filtering processes.

In the case of the sedimentation filter, activated carbon filter, and hollow fiber membrane filter used in the water purifier, a filter case in which a filter material (for example, activated carbon filter is activated carbon) is stored in the outer case is stored inside the outer case. In general, a structure in which the purified water obtained through the communicating inlet is filtered by the filter material in the filter case and then discharged through the outlet of the outer case.

In general, as shown in FIG. 1, a water filter includes a composite filter for storing the activated carbon filter unit 10 and the hollow fiber membrane filter unit 20 in one exterior case 1 to filter the purified water subjectively. The outer case 1 includes an inlet 1a through which water is introduced and an outlet 1b through which the introduced water is discharged to the outside.

In addition, the activated carbon filter unit 10 and the hollow fiber membrane filter unit 20 are sequentially stored inside the outer case 1, in which the activated carbon filter unit 10 is an inlet 1a of the outer case 1. The hollow fiber membrane filter unit 20 is disposed at the outlet 1b side of the outer case 1.

The activated carbon filter unit 10 and the hollow fiber membrane filter unit 20 are in close contact with each other, so that water passing through the activated carbon filter unit 10 passes through the hollow fiber membrane filter unit 20 to be more effectively filtered. .

The activated carbon filter unit 10 is disposed to form a passage through which water passes between the inner wall of the outer case 1, and the activated carbon filter unit 10 passes through the activated carbon filter unit 10. A core 11a is formed to allow water to flow toward the hollow fiber membrane filter unit 20.

That is, the purified water introduced into the interior through the inlet 1a of the outer case 1 avoids one end of the activated carbon filter unit 10 and the inner walls of the activated carbon filter unit 10 and the outer case 1. As it flows along a passage formed therebetween, it moves toward the core 11a through the side of the activated carbon filter unit 10.

Water is leaked due to the water pressure to the parts in contact with each other when the water is introduced.

In addition, conventionally, a problem occurs in that water flows directly to the hollow fiber membrane filter unit without passing through the activated carbon filter unit through a passage formed between the activated carbon filter unit and the outer case, thereby lowering the efficiency of the filter.

Furthermore, in the related art, water passing through the activated carbon filter part is rapidly introduced into the hollow fiber membrane filter part, and there is a serious problem that the hollow fiber membrane filter part is damaged by the inflow water pressure.

The present invention has been proposed to solve the problems described above, the purpose of which is to facilitate the assembly of the composite filter by combining the activated carbon filter unit and the hollow fiber membrane filter unit constituting the composite filter of the water purifier, the exterior after assembly Even if it is embedded in the case, the airtightness between the activated carbon filter unit and the hollow fiber membrane filter unit is maintained.
