うにした各種の浄水器が提案されている。For example, tap water generally contains very small amounts of residual chlorine, etc., which causes unpleasant sensations such as odor, when it is made for drinking. Therefore, various water purifiers have been proposed in which the residual chlorine and the like are removed by filtering the tap water using a filtering agent such as activated carbon.
（発明が解決しようとする問題点〕
ところが上記浄水器では、水を止めた場合、その構造上

I try to drain the waste water before using it. However, even if I use this method, viscous substances caused by various bacteria gradually adhere to the surfaces that come in contact with the accumulated water, and this becomes a nest for various bacteria and can easily be used. It becomes difficult to wash away.

Become. If this residence time becomes longer, there is a concern that bacteria may breed in the residence water. These germs have a tendency to grow particularly easily in areas such as purified water hoses that are in contact with the inner surface of the passageways. In this embodiment, since the antibacterial agent 14 having a contact sterilization effect is exposed on the inner surface 3b of the purified water hose 3, it is possible to efficiently sterilize various germs near the inner surface 3b and prevent their proliferation. can.
