[0006] The "Water Purifier Filter Assembly" in Korean Patent Registration No. 10-1447907 (registered on September 30, 2014) allows fluid to be opened and closed simply by attaching and detaching the filter cartridge, and has a simplified structure that is highly effective for manufacturing and maintenance. It is equipped with structural means to reduce excessive cartridge removal force caused by pressure inside the filter assembly when the filter cartridge is separated, and provides structural means that allows the fastening position to be easily set when fastening the filter cartridge.

[0007] In addition, the Korean Patent Nos. 10-2279332 and 10-1447907 disclose in detail a structure configured such that raw water flows in one direction and purified water is discharged after being filtered by a filter.

[0008] Korean Patent No. 10-1317643, "Polyamide nanocomposite membrane and manufacturing method thereof," provides technology for a polyamide nanocomposite consisting of a polyamide active layer formed to contain an organic phosphate. [Prior art documents] [Patent documents]

[0026] In order to fully understand the present invention, preferred embodiments of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention can be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. These embodiments are provided to more completely explain the present invention to those having average knowledge in the art. Therefore, the shapes of elements in the drawings may be exaggerated to emphasize a clearer description. It should be noted that the same elements in each view may be denoted by the same reference numerals. Detailed descriptions of well-known functions and configurations that are deemed to be likely to unnecessarily obscure the gist of the present invention will be omitted.

[0027] The present invention is a water purification filter that is installed in a water purifier and is configured to have the ability to suppress the formation of scale caused by hard substances such as limestone contained in the raw water and to remove viruses contained in the raw water.

[0028] The water purification filter having the ability to inhibit scale generation and remove viruses according to the present invention is a water purification filter that is installed in a water purifier and is configured to inhibit the generation of scale caused by hardness and limescale contained in raw water and remove viruses (including microorganisms) so that the final filter is not contaminated with viruses and their proliferation does not occur.

[0029] Scale that forms in water purifiers generally forms at the rear end of the hot water module, blocking the product flow path and reducing the flow rate of hot water, as well as causing problems such as valve errors and excessive extraction noise.

[0030] Generally, among the hardness substances present in water, calcium and magnesium combine with carbonates to exist in the form of calcium carbonate and magnesium carbonate. When the temperature rises, calcium carbonate precipitates, and magnesium carbonate and iron combine with the precipitated calcium carbonate to form scale.

[0031] Polyphosphates have a greater affinity for calcium, magnesium, and iron than carbonates and have the ability to inhibit the formation of scale.

[0032] The water purification filter having the ability to inhibit scale generation and remove viruses according to the present invention will be described in more detail with reference to the accompanying drawings showing an embodiment thereof.

[0051] The polyphosphate used is generally in the form of polyphosphate beads having a size of 1 / 16 inch to 1 / 4 inch.

[0052] Generally, polyphosphate beads have the property of slow dissolution, making them very useful for sustained and stable phosphate (PO4) water treatment.

[0053] The polyphosphate beads as the phosphate beads 240 can maintain water transparency by isolating minerals and controlling scale, and can inhibit corrosion of the entire drainage pipe, thereby reducing corrosion.

[0054] The polyphosphate beads are formed into particles, or are formed into one of pellets cut to a predetermined size by extrusion, or powder (contained in a bag).

Let it close The filter housing 100 includes a supply passage 140, which separates raw water from the filter housing 100. The filter housing 100 receives raw water from the outside and supplies it to the supply passage 140. The filter unit 200 is installed so that the raw water supplied to the supply passage 140 moves from the particulate matter removal filter 212 toward the central outlet passage 250 and is purified.

[0057] The upper cover 310 has a filter fixing protrusion 311 protruding downward from the center of the interior thereof, and the post-carbon filter 230 is fitted inside or outside the filter fixing protrusion 311 to maintain a fixed state, thereby stably maintaining the fixed state of the post-carbon filter 230.
