Description

[0001]
TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to an electrolytic cell provided with an electrode that elutes in water to be treated.
[0002]
[Prior art]
A conventional electrolytic cell provided with an electrode to be eluted is disclosed in, for example, JP-A-63-166490. According to this publication, an electrolytic cell provided with an electrode to be eluted (silver electrode) is provided with an outlet of a supply conduit on the bottom surface, and an inlet of a discharge conduit on the ceiling surface, and is provided above the supply conduit. The silver electrode is provided at a position facing the outlet opening at the bottom. When a voltage is applied to the silver electrode, silver ions are eluted from the silver electrode into the treated water to become silver ion water.

[Problems to be solved by the invention]
However, the diffusion of silver ions in the electrolytic cell depends on the water flow in the electrolytic cell. Therefore, silver ions having a higher specific gravity than water molecules tend to stagnate and accumulate on the inner bottom surface of the electrolytic cell. Silver ions are wasted without being diffused.
In addition, the electrode to be eluted reacted with chloride ions and the like in tap water even when electricity was not applied, and formed a precipitate on the electrode surface. Therefore, when water is supplied and electricity is supplied while the precipitate is formed, the precipitate is discharged out of the electrolytic cell together with the silver ion water.
[0004]
The present invention has been proposed in view of the above-mentioned drawbacks inherent in the prior art, and has been proposed to solve the problem suitably. To provide an electrolytic cell that efficiently diffuses ions eluted from an electrode. With the goal.
Still another object of the present invention is to provide an electrolytic cell that prevents a precipitate formed on an electrode surface from being discharged out of the electrolytic cell.
[0005]
[Means for Solving the Problems]
In order to overcome the above problems and achieve the intended purpose, an electrolytic cell according to the present invention is provided with a supply pipe for supplying water to be treated into a tank provided with an electrode to be eluted, and a treatment pipe in the tank. And a discharge line for discharging the water, wherein an outlet of the supply line opens downward toward the electrode. The electrolytic cell according to claim 2 includes a filter joined to an outlet of a supply pipe, and the electrode is disposed in the filter.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an electrolyzer according to the present invention will be described below with reference to the accompanying drawings by way of preferred embodiments.
[0007]
1 and 2 show a first embodiment according to the present invention, in which an electrolytic cell 10 penetrates a resin electrolytic cell main body 12 and a substantially central portion of a ceiling surface 12a of the electrolytic cell main body 12, and extends downward. A supply conduit 14 extending, a discharge conduit 16 opening to the ceiling surface of the electrolytic cell main body 12, a silver electrode 18 penetrating through the bottom surface 12b of the electrolytic cell main body 12 and extending toward an outlet of the supply conduit 14; It is composed of
When the solenoid valve 20 is opened in response to an injection signal from an injection switch (not shown), water to be treated such as tap water supplied from an external water supply source is supplied to the electrolytic cell 10. The water to be treated is supplied to the silver electrode 18 from an outlet 14a which opens downward through the supply pipe 14. The silver electrode 18 is energized by the DC power supply 22 in accordance with the above-described pouring signal, and the energization causes the silver electrode 18 to gradually become silver ions and dissolve into the water to be treated. The treated water in which the silver ions are dissolved is taken out from the discharge line 16 and used for drinking water, food processing, disinfecting treatment water, and the like.
As described above, since the outlet 14a of the supply pipe 14 is configured to open downward toward the silver electrode 18, the silver ions can be efficiently diffused by the water flow, and the stagnation and accumulation of the electrolytic cell body 12 can easily occur. The silver ions on the bottom surface 12a are also diffused, so that silver ion water having a uniform concentration can be generated.
[0008]
FIG. 3 shows a second embodiment according to the present invention, in which a filter 24 for preventing a precipitate from being discharged to the electrolytic cell 10 of the first embodiment is provided. The filter 24 has a cylindrical shape and is disposed from the outlet 14a of the water supply pipe 14 to the bottom surface 12b of the electrolytic cell main body 12, and the silver electrode 18 is disposed inside the cylindrical shape. The filter 24 may be any filter that allows the passage of water molecules and silver ions and does not allow the precipitate to pass.
As described above, since the filter 24 is provided, when the silver electrode 18 is energized, it reacts with chloride ions or the like in tap water, and a precipitate appears on the surface of the silver electrode 18, and this precipitate is about to be discharged together with the treated water. The filter 24 prevents only the precipitate from being discharged, so that the precipitate is taken out of the discharge line 16 and mixed with the drinking water, food processing, disinfecting treatment water, etc., and the precipitate is mixed to give a sense of mistrust. Nothing.
[0009]
In the first and second embodiments, the silver electrode has been described as an electrode. However, the present invention is not limited to this. Any electrode that can be eluted, such as a gold electrode or a copper electrode, may be used.
[0010]
【The invention's effect】
As described above, according to the electrolytic cell of the present invention, since the outlet of the supply pipe is opened downward toward the electrode, ions eluted from the electrode can be diffused efficiently.
