TECHNICAL FIELD The present invention relates to a cartridge filter structure, and more particularly, to a cartridge filter in which a purified or soft water material is filled in a cartridge, and water is purified or softened while passing through these materials.

In recent years, a water purifier for filtering impurities so that water can be used for drinking water and a softener for softening by removing water ions by ion exchange method are widely used.

 Various water purification materials are used to filter the water, depending on the filtration stage.These types include needles such as fibers and resins that can filter out sand, soil, rust in water pipes, and other relatively large particles. Synthetic membrane to filter out specific purified materials such as deodorizing purified water such as granular activated carbon to remove chlorine and other chemicals added during water disinfection, and fine materials such as heavy metals, phenols, carcinogens, Escherichia coli, viruses and bacteria Water purification materials for removing fine substances such as hollow fiber membranes, and water purification materials for removing harmful gases such as activated carbon for finally removing harmful gases and odors in water. In addition, ceramics may be used as a purified material. As soft water material for softening water, ion exchange resin is mainly used.

These purified materials or ionic materials are used after being filled in a cylindrical cartridge having inlets and outlets at both ends. In particular, in the water purifier, the above-mentioned various kinds of water purification materials are filled in separate cartridges and used by connecting them with a hose. The movement path of the water introduced into these cartridges and the foreign matter contained in the water is a straight path from the cartridge inlet to the outlet.

The foreign matter contained in the water is filtered or ion exchanged only by the purified or soft water in contact with the moving path. Therefore, by extending the length of the moving path of the foreign matter contained in the water and the water inside the cartridge or by expanding the cross-sectional area of the moving path it is possible to enhance the water purification effect or ion exchange effect.

However, when water and foreign matter moves straight inside the cartridge, there is only a method of increasing the length and diameter of the cartridge in order to increase the path length and cross-sectional area of the water and the foreign matter. Water purifiers and water softeners are mostly installed in a narrow space, so the smaller the volume is, the more preferable. When the length or diameter of the cartridge is increased to increase the water purification effect or ion exchange effect, the volume of the cartridge filter and the volume of the water purifier or water softener accommodating the water are increased. There is a drawback that is too large. Therefore, it is necessary to devise a way to increase the length or cross-sectional area of the movement path of water and foreign matters without increasing the volume of the cartridge.

In order to increase the flow path of water and foreign matter, a cartridge type may be abandoned, and a hose may be wound in a spiral shape, and a water purification material or an ionic material may be filled in the hose. However, when the diameter of the hose is increased, it is difficult to spirally wind it up, and when the diameter is reduced, a large amount of unnecessary space is generated inside the wound hose, so that the volume cannot be reduced. There is a disadvantage that can not fill the purified material or soft water material is not to be adopted.

The present invention devised to solve the problems of the above-described cartridge filter for water purifiers or water softeners can maximize the opportunity to contact the purified water or soft water with foreign substances in water and water in the cartridge having a constant volume The flow path is to provide an extended cartridge filter.

Another object of the present invention is to provide a cartridge filter having an extended flow path that can minimize the number of cartridges installed in a water purifier or a softener by allowing another type of purified or soft water to be filled in one cartridge. .
