Description

[Detailed explanation of the idea] The present invention relates to a non-diaphragm electrolytic cell for a continuous ion water conditioner.

Ionic water conditioners are devices that use electrolysis to separate water in a container (electrolytic cell) into alkaline water and acidic water, and extract this alkaline water as drinking water, and are easily used in general households. .

The electrolytic cells of conventional ionic water conditioners are divided into two chambers by a permeable or semi-permeable diaphragm, and electrodes are placed in each chamber to form a cathode chamber and an anode chamber (
・Ru.

The ionized alkali ions and acidic ions pass through the diaphragm and collect in the cathode chamber and the anode chamber.

In such an electrolytic cell, scale and dirt adhere to the diaphragm, making it unsanitary, so the diaphragm must be cleaned together with the electrodes.

In addition, when used for a long time, ionic components contained in water,
For example, components such as Ca++, Na+, s=, cl-, etc. can cause clogging of the diaphragm and reduce electrolytic efficiency, so it is sometimes necessary to remove it from the electrolytic cell and either wash it or replace it with a new diaphragm.

Usually, the diaphragm is placed in close contact with the bottom or side wall of the electrolytic cell, so inserting or removing the diaphragm is quite cumbersome, and it may be damaged when it is attached or removed.

The purpose of this invention is to provide a non-diaphragm electrolytic cell that can separate and extract water with a high concentration of alkaline ions and water with a high concentration of acidic ions without using a diaphragm in a continuous ion water conditioner. It is something to do.

Hereinafter, the present invention will be described in terms of embodiments with reference to the drawings.

1 and 2 are a longitudinal sectional view and a cross sectional view, respectively, schematically showing a non-diaphragm electrolytic cell 1 of a continuous ion water conditioner according to an embodiment of the present invention. The arrows indicate the flow of water.

The electrolytic cell 10 case 10 has a cylindrical cross-sectional shape,
A water supply port 11 is provided at the bottom of the case, and a water sampling port 12 is provided at the top for taking out alkaline water and acidic water.
, 13 are provided.

A cylindrical anode rod 14 is attached to the center of the case 10 and extends over almost the entire length of the case.

Annular protrusions 15 and 16 are formed on the bottom inner wall and the top inner wall of the case 10 so as to be concentric with the pole rod, and a cylindrical cathode 18 is attached to the annular protrusions 15 and 16.

A plurality of holes 19 are bored in the circumferential surface of the cathode 180, as shown in the vertical cross-sectional view of FIG.

In this way, the cylindrical anode rod 14 and the cylindrical cathode 18
are arranged concentrically with each other.

A diversion port 22 is formed in the annular protrusion 15 at the bottom of the case, which communicates the outer circumferential portion of the cathode 18 with the inner zero portion of the cathode 18 (the portion between the cathode 18 and the anode rod 14).

As shown by the arrow, water from the water supply port 11 is sent to the outside of the cathode 18 and between the cathode 18 and the anode rod 14, flows upwards of the case 10, and flows to the water sampling ports 12, 1.
It is taken out from 3.

In the illustrated embodiment, the alkaline water sampling port 12 opens near the outer periphery of the cathode 18 at the top of the case, and the acidic water sampling port 13 opens near the outer periphery of the cathode 18.
A passage 23 passing through the annular protrusion 16 in the case outer shell and top inner wall opens near the outer periphery of the anode rod 14, specifically between the anode rod 14 and the cathode 18.

The anode rod 14 and the cathode 18 are connected to a DC power source 24.

Incidentally, each water sampling port 12.13 is connected to a suitable pipe (not shown) for leading the ionized water to the outside.

How to adjust the water sampling flow rate. It is adjusted by the nozzle diameter of each pipe or a valve (not shown) provided on the pipe, or by a similar method on the water supply port side.

Note that, although not shown, a so-called air trap may be provided in the pipe portion of the water sampling port to prevent water from flowing back from the pipe due to a siphon phenomenon.

In such a configuration, the water inlet 11 is connected to, for example, a water outlet in a general household, and water is continuously fed into the tank, and a current is caused to flow between the electrodes 1418 by the DC power supply 24.

As mentioned above, since a plurality of holes 19 are formed on the circumferential surface of the cylindrical cathode, the water on the outside and inside of the cathode is subjected to the ionization effect caused by the energization between the electrodes, and the flowing water in the tank is supplied with water. On the way from the mouth 11 to the upper part, the acidic ions of the water collect around the anode rod 14, and the alkali ions gather around the cathode 18.
The particles are concentrated in close proximity to the inner circumferential surface of the cathode 18, and further to the outer portion of the cathode 18 through the aperture 19.

Such ionization of water becomes more noticeable as the flowing water moves toward the top of the tank, and the flowing water becomes alkaline water in the portion connected to the water sampling port 12 at the top of the tank, and becomes acidic water in the portion connected to the water sampling port 13.

In this way, the openings 19 allow the cathode 18 to function effectively as an electrode despite its cylindrical circumferential surface, and to transfer the generated alkaline water and acidic water to the outside and inside of the cathode 18, respectively. Therefore, sufficient ionized water can be generated without providing a conventional diaphragm between the two electrodes.

Furthermore, because of its cylindrical shape, the cathode 18 has a larger contact area with water for an electrolytic cell of the same volume than a flat cathode, which can improve electrolysis efficiency.

Therefore, it is useful when applied to a continuous type ion water conditioner for running water, and it is possible to reduce the overall length and volume of the electrolytic cell to create a simple home ion water conditioner with large capacity. You can do it.

In the above embodiment, the anode is placed in the center of the case and the cathode is placed on the outside, but this can be reversed and the cylindrical anode is placed on the outside and the rod-shaped cathode is placed in the center. It is clear that these are also included in the present invention.

The key point of the present invention is that two electrodes are arranged concentrically and spaced apart without providing a diaphragm, which has the effect of eliminating the reduction in electrolytic efficiency due to clogging of the diaphragm and the complexity of cleaning the diaphragm.
