Abstract
A filter member including a cylinder part extending in one direction, a filter hollow part which is formed inside the cylinder part to pass through along the one direction and allows the inside of the cylinder part to be in communication along the one direction, and a filtering part disposed to surround the cylinder part from radially outside and configured to filter raw water flowing through the filter hollow part.
Claims16
A filter member, comprising:
- a cylinder part extending in one direction;
- a filter hollow part which is formed inside the cylinder part to pass through along the one direction and allows the inside of the cylinder part to be in communication along the one direction;
- and
- a filtering part disposed to surround the cylinder part from radially outside and configured to filter raw water flowing through the filter hollow part,
- wherein the filtering part comprises:
- a main filtering part which has one end coupled to the outer circumferential surface of the cylinder part and extends from the one end toward the other end and which is wound at least one time along the outer circumferential surface of the cylinder part to surround the outer circumferential surface of the cylinder part;
- and
- a sub-filtering part which has one end coupled to the other end of the main filtering part and extends from the one end toward the other end and which is wound along the outer circumference of the main filtering part to surround the outer circumference of the main filtering part,
- wherein the sub-filtering part comprises a plurality of openings forming passages which the raw water passes through to enter the main filtering part.

A filter structure, comprising:
- a housing having an accommodation space formed therein that communicates with the outside;
- a filter member accommodated in the accommodation space of the housing and configured to filter raw water delivered from the outside to produce purified water or living water;
- and
- a conduit unit extending in one direction and communicating the accommodation space and the filter member accommodated in the accommodation space with the outside,
- wherein the filter member comprises:
- a cylinder part extending in the one direction;
- a filter hollow part formed through the inside of the cylinder part along the one direction, a portion of which communicates with the conduit unit and the accommodation space;
- and
- a filtering part disposed to surround the cylinder part from radially outside and configured to filter raw water flowing through the filter hollow part,
- wherein the conduit unit comprises:
- an inlet conduit extending through the portion of the filter hollow part and communicating with the accommodation space;
- and
- an outlet conduit accommodated in the remaining portion of the filter hollow part, and communicating with the filter part, but being blocked from communication with the accommodation space and the inlet conduit,
- wherein the filtering part comprises:
- a main filtering part arranged to surround the outer circumferential surface of the cylinder part;
- and
- a sub-filtering part arranged to surround the outer circumferential surface of the main filtering part and having a plurality of openings formed therethrough in communication with the accommodation space, and
- wherein the raw water delivered to the accommodation space sequentially passes through the sub-filtering part and the main filtering part and flows toward the outlet conduit.
