Description

Water Purification System Using Ultraviolet LEDs {WATER PURIFIER SYSTEM USING UVTRAVIOLET LIGHT EMITTING DIODE}

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

A water purifier is a device used to filter water into purified water.

The water purifier purifies the water introduced through the raw water supply unit through various filters, stores the purified water in the purified water tank, and discharges the water to the outside through the intake coke.

The water purification method used in such a water purifier may be classified into filtration, distillation, ion exchange resin, or reverse osmosis.

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

The activated carbon filtration type is used a lot of methods using activated carbon excellent in odor removal function such as residual chlorine.

The reverse osmosis is a method using a phenomenon that the material moves through the membrane, the water molecules pass through the membrane by pressing one side of the membrane and leaving the contaminants.

In recent years, such a water purifier has been equipped with a UV filter equipped with a UV lamp that emits UV light, in order to sterilize bacteria remaining in the filtered water.

However, the conventional UV filter has a disadvantage in that the sterilization efficiency is poor because the filtered water is provided in a simple form having a UV lamp in the pipe through which the filtered water passes.
