## Abstract

An ultraviolet ray sterilizer for a water pipe and a waterway featuring a plurality of circular flow ways that are formed, and an ultraviolet lamp is provided at the center of the flow ways, thus removing a sterilization dead zone where sterilization is not performed.

## Claims

### Claim 1

An ultraviolet ray sterilizer for a water pipe and a waterway configured to be connected at a water pipe or a waterway through which a treatment water to be sterilized flows for thereby sterilizing by radiating ultraviolet rays to the treatment water flowing in the ultraviolet ray sterilizer, comprising:
a housing in which a plurality of cylindrical flow ways connected from an inlet to an outlet are arranged at upper and lower sides in multiple rows, and a pass channel cut-away along a longitudinal direction between neighboring flow ways, and at an upper side of a flow way positioned on the upper most portion is formed an inlet which is open along a longitudinal direction, and the inlet and the outlet are configured to be connected with the water pipe or the water way in such a way to communicate with the water pipe and the water way;
a hanger including a cover covering the inlet of the housing, a hanger member extended from an upper side to a lower side as the hanger member is hung on the cover, and a plurality of crystal tubes which each are a tubular member, an end of which is closed and an end of which is open, and which are arranged matching a row of the plurality of cylindrical flow ways of the housing, the plurality of crystal tubes being supported by the hanger member; and
an ultraviolet ray lamp including a lamp part inserted into the open end of each crystal tube and a cap part engaged to one end of the lamp part and covering the open end of the crystal tube.

### Claim 2 (depends on 1)

The sterilizer of claim 1, wherein the hanger includes a blocking member which is supported by the hanger member between neighboring crystal tubes and is positioned at the pass channel so as to block the pass channel of the housing in a state that the plurality of crystal tubes of the hanger are positioned at the centers of the flow ways.

### Claim 3 (depends on 1)

The sterilizer of claim 1, wherein the hanger includes a titanium dioxide coating layer of a thin film form through which passes ultraviolet rays on an outer surface of the plurality of crystal tubes.

### Claim 4 (depends on 4)

The sterilizer of claim 4, wherein the hanger includes a titanium dioxide coating layer of a thin film form through which passes ultraviolet rays on an outer surface of the plurality of crystal tubes.
