Abstract:
1. A water battery device comprising a container and an inner unit disposed at an inside of the container: the inner unit including; a first reactor made of a first metal having a predetermined ionization tendency so as to produce metal ions in a running water to perform a sterilization effect, a second reactor made of a second metal having an ionization tendency lower than the first metal, the second reactor having a facing surface disposed in a facing manner to an entire surface of a main portion of a metal ion producing surface on an overall surface of the first reactor, and an interval keeping member fixedly holding the first reactor and the second reactor such that the first reactor and the second reactor are kept in an untouched state with each other over their entire surfaces and such that the first reactor and the second reactor planarly face to each other with an clearance space, the interval keeping member keeping the first reactor and the second reactor from being electrically conducted so as to electrically insulate the first reactor and the second reactor, and the container including a communication hole allowing the running water to communicate between an outside of the container and the inner unit disposed at the inside of the container; wherein the inner unit makes the metal ions dissolve into the running water by a battery action between the first reactor and the second reactor to produce a treated water when the running water is passed through the communication hole to the inside of the container, the battery action being produced by use of a medium consisting of only the water entering into the clearance space, wherein the container has an indirect flow-in/flow-out container structure that provides the communication hole only at such a position that allows the treated water at the inside of the container to be drawn out by the running water flowing at the outside of the container, wherein, as the indirect flow-in/flow-out container structure, the container has either of a first structure, a second structure or a third structure, wherein, in the first structure, the container has a tubular shape with a first closed end and a second closed end at axially opposite ends and is adapted to be disposed along an axis of a water conduit of a water pipe so that the second closed end is located at a downstream side in the water conduit, and the communication hole is provided only at the second closed end of the container to allow the treated water at the inside of the container to be drawn out by the running water flowing around the communication hole, wherein, in the second structure, the container has a tubular shape with a first closed end and a second closed end at axially opposite ends and is disposed perpendicularly to an axis of a water conduit of a water pipe so that the second closed end faces perpendicularly to the axis of the water conduit, and the communication hole is provided only at the second closed end of the container to allow the treated water at the inside of the container to be drawn out by the running water flowing around the communication hole, and wherein, in the third structure, the container has a tubular shape with a first open end and a second open end at axially opposite ends and has the first open end fitted at a downstream end of a water conduit of a water pipe so that an axis of the container is coaxial with the axis of the water conduit, the inner unit has the first reactor and the second reactor formed respectively into a cylindrical shape and arranges the first reactor and the second reactor in a coaxial manner, the container houses therein the inner unit in an coaxial manner, and the communication hole is provided on an inner one of the first reactor and the second reactor at a position near the first open end so as to penetrate the inner one in a direction perpendicular to the axis of the container to allow the treated water at the inside of the container to be drawn out by the running water flowing around the communication hole.
