PURPOSE: A module for circulating purified water through an UV filter is provided in which the UV filter for sterilizing purified water stored in a purified water tank and a circulation pump for circulating the purified water under certain conditions are integrally constructed in a way that they are modularized for easy assembling and dissembling. CONSTITUTION: The module for circulating purified water through an UV filter comprises an UV filter part(20) in which the UV filter part(20) is divided into an outer case(21) and an inner case, a purified water inflow hole(1) is formed in a middle part between the cases, a cap(23) is coupled to one end of the cases in the state that the cap(23) is attached or detached by a locking element(36) and a coupling hole(35), a locking element(39) is formed on the outer circumference of the other end of the cases, the locking element(39) is removably coupled to a coupling hole(35') formed on the outer circumference of a connection member(40) of the circulation pump part(60), and a connection pipeline(32) onto which an O-ring(27') is slid is projected from the end part of the cases; and a circulation pump part(60) one end of which is removably coupled to the connection pipeline(32) of the UV filter part(20), the other end of which is coupled to the case of a circulation pump, and in which the connection member(40) is equipped with a pipeline(45) and a female grooved part(42) into which the connection pipeline(32) is inserted, grooves into which a rotation shaft(65) of an impeller and a position determining pin(66) are inserted are respectively formed at the other end of the connection member(40) so that the grooves are accurately coupled to a case of the circulation pump part(60) and the rotation shaft(65) of the impeller(63), and the impeller(63) having the rotation shaft(65) parallel to the central shaft is installed at the left side part of the case(61) of the circulation pump part(60) so that purified water passing the pipeline(45) of the connection member(40) is transferred to a purified water outflow hole(2) formed on the upper part of the impeller(63).
