The present invention relates to a water storage tank for storing water an inflow circulation pipe into which the water stored in the water storage tank flows a discharge circulation pipe extending in a direction parallel to the extension direction of the inflow circulation pipe And a bent circulation pipe which is connected to one side of the circulation pipe and one side of the discharge circulation pipe and is bent so as to have a predetermined curvature, and a bent circulation pipe which is connected at one side to the water storage tank and on the other side to the discharge coke A protruding portion which is provided in an internal space of the water intake conduit and projects inward from an outer surface of the water intake conduit is formed on one side of the discharge circulation pipe, Is a boundary between the discharge circulation pipe and the water intake pipe so that water moves from the discharge circulation pipe along the inner lower surface of the intake pipe in the direction of the discharge coke In which a guide hole for providing a movement path of water is formed, and more particularly to a water purifier having a circulation sterilization system.(FIG.本発明は、水を貯留する貯水槽;前記貯水槽に貯留された水が流入される流入循環管と、前記流入循環管の延長方向と平行な方向に延在する排出循環管と、前記流入循環管の一方側と前記排出循環管の一方側とを接続し所定の曲率を持つように折り曲げられる折り曲げ循環管とを含む循環管路;及び一方側が前記貯水槽に接続され他方側が排出コークに接続される取水管路;を含み、前記排出循環管の一方側には、前記取水管路の内部空間に設けられて前記取水管路の外面から内側に突出する突出部が形成され、前記突出部には、前記排出循環管から前記取水管路の内部下面に沿って前記排出コークの方向に向けて水が移動するように、前記排出循環管と前記取水管路との間の境界であって水の移動通路を提供するガイドホールが形成される、循環殺菌システムを備えた浄水器に関する。【選択図】図2
