Description

Water Purification System using UV LED {WATER PURIFIER SYSTEM USING UVTRAVIOLET LIGHT EMITTING DIODE}

The present invention relates to a water purification system using ultraviolet LEDs.

A water purifier is a device used to filter water to make it purified.

The water purifier is a device that purifies water flowing through a raw water supply unit through various filters, stores the purified water in a water purification tank, and discharges it to the outside through a water intake coke.

The water purification method used in the water purifier can be classified into a filtration method, a distillation method, an ion exchange resin method, or a reverse osmosis pressure method.

In this case, the filtration type may be classified into a micro filter type, an activated carbon filtration type, or a hollow fiber filter filtration type, depending on the type of filter used.

The activated carbon filtration method is a method using activated carbon having excellent odor removal function such as residual chlorine.

The reverse osmosis type is a method using a phenomenon in which a substance moves through a membrane, and a water molecule is pushed on one side of the membrane to pass a membrane and a contaminant is left.

Recently, such a water purifier was equipped with a UV filter equipped with UV, that is, a UV lamp that emits ultraviolet rays to sterilize bacteria remaining in the filtered water.

However, the conventional UV filter is provided in a simple form having a UV lamp in a passage through which the filtered water passes, so that the filtered water does not secure a sufficient sterilization time, and thus has a disadvantage of poor sterilization efficiency.
