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 use electrolytic action to separate the 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. There is.

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

Ionized alkali ions. Acid 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 red + -Ca, Na, S, and CI can clog 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 present invention uses a continuous ion water conditioner (4) to separate water with a high alkaline ion concentration and water with a high acidic ion concentration without using a diaphragm 4 and take it out, and is also easy to disassemble and clean. Some are intended to provide electrolytic cells.

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

FIG. 1 is a vertical cross-sectional view schematically showing a non-diaphragm electrolytic cell 1 of a continuous ion water conditioner according to an embodiment of the present invention, and in FIG. 1, the flow of water in the tank is indicated by arrows. be.

The case 10 of the electrolytic cell 1 has a cylindrical cross-sectional shape,
A water supply port 11 is provided at the bottom of the case.

At the bottom of the case 10, an annular protrusion 15 is formed concentrically with the axis of the case.

A metal cylindrical flange 27 is attached to the bottom of the case with mounting screws 28 in contact with the outer circumference of this annular protrusion 15.

As shown in the figure, (1) a cylindrical cathode 18 is attached to the upper end of the cylindrical flange 27; It is supposed to be done.

A plurality of openings 19 are formed in the circumferential surface of the cathode 180.

On the back side of the upper lid 25, there is an annular protrusion 15 at the bottom of the case 10.
An annular protrusion 16 having the same outer diameter is formed.

A cylindrical partition wall 17 extending downward to an appropriate length is fixed to the inner peripheral surface of the annular projection 16 of the upper lid 25.

This partition wall is intended to prevent alkaline water and acid water generated from mixing with each other as described later, and there is no need to make the total length of the partition wall very long.
It is preferable to keep the length so that it is located near the top of the case 10 when attached to the case 10.

In the illustrated embodiment, a cylindrical anode rod 14 having threaded portions 14a and 14b at both ends is attached to the center of the case 10.

To attach the anode rod 14, the threaded portion 14b at the lower end thereof is passed through the hole 26 at the bottom of the case 10 and fixed with a nut 39, and the cathode 18 is attached to the annular protrusion 15 at the bottom of the case.

Attach the upper cover 25 to the case 10, and pass the threaded portion 14a at the upper end of the anode rod 14 through the through hole in the center of the upper cover.

Tighten it from above with a tightening screw 30 as shown.

At this time, the upper end of the cathode 18 should be tightly fitted to the outer peripheral surface of the annular projection 16 of the upper cover 25, and the upper cover should also be fixed to the case 10 with the tightening screws 30.

The upper lid 25 is further provided with water sampling ports 12, 13 for taking out the generated alkaline water and acidic water.

The alkaline water sampling port 12 communicates with the vicinity of the outer periphery of the cathode 18 at the top of the case, and the acidic water sampling port 13 communicates with the inside of the partition wall 17 through a passage 23, that is, near the upper periphery of the anode rod 14. .

The anode rod 14 and the cathode rod 18 each have a threaded portion 14 at the lower end.
b and cylindrical flange 27. It is connected to a DC power source 24 via a mounting screw 28.

A diversion port 22 is formed in the annular protrusion 15 at the bottom of the case, which communicates the outer portion and the inner portion of the cathode 18 (the portion between the cathode 18 and the anode rod 14). The water on the outside of the cathode 18 and the cathode 1
8 and the anode rod 14, flows upward in the case 10, and is taken out from the water sampling ports 12 and 13.

Incidentally, each of the water sampling ports 12 and 13 is connected to a suitable pipe for leading out the ionized water to the outside.

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

Note that a so-called air trough 40, 41 may be provided in the pipe portion of the water sampling port to prevent water from flowing backward from the pipe due to a siphon effect.

In such a configuration, the water inlet 11 is connected to, for example, a water outlet in a general household, water is continuously fed into the tank, and a current is caused to flow between the electrodes 14 and 18 by the DC power supply 24.

As mentioned above, since a plurality of openings 19 are formed on the circumferential surface of the cylindrical cathode, the water outside and inside the cathode is ionized by the current flowing between the electrodes, and the flowing water in the tank becomes the water supply. On the way from the mouth 11 to the upper part, acidic ions of water gather around the anode rod 14, and alkaline 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 electrodes on both sides despite its cylindrical shape.
Moreover, the generated alkaline water and acidic water are separated into the outside and inside of the cathode 18, respectively, so that sufficient ionized water can be produced without providing a conventional diaphragm between the two electrodes. , w can be brought about efficiently.

Furthermore, in this invention, the cathode 1 is placed at the top of the case near each water sampling port.
8 and the anode rod 14 are separated by a partition wall 17. Therefore, a cathode chamber is formed on the outside and an anode chamber is formed on the inside with this partition wall as a boundary. Alkaline water near the cathode and acidic water near the anode do not mix together.
They are completely separated and sprout into their respective water intake ports.

Since the partition wall 17 is located only near the top of the case, it does not affect the electrode action of the tank as a whole.

Since the present invention does not have a diaphragm, there is no need to clean it, but it is also very easy to disassemble the anode and cathode after use and clean the electrodes and the inside of the tank.

Hereinafter, the structure of the cathode according to the present invention and its attachment/detachment operation will be explained with reference to FIGS. 2 and 3.

FIG. 2 is a partial side view showing in detail the state in which the cathode 18 is attached to the cylindrical flange 27 attached to the annular protrusion 15 (FIG. 1) at the bottom of the case, and FIG. 3 is the same as that shown in FIG. ■−■
It is an enlarged sectional view along the line.

As shown in the figure, a plurality of through holes 19 are formed in the circumferential surface of this cathode 180 made of a conductive metal.

Also formed on the circumferential surface of the cathode 18 near its flat end are a pair of protrusions 32, 33 spaced apart along the length of the cylinder.

The first protrusion 32 has a shape extending slightly in the circumferential direction, and the second protrusion 33 is a circular protrusion. It is an impressive structure that protrudes from the inside of the side wall to the outside.

The cathode 18 is inserted into the cylindrical flange 27 in contact with its inner periphery, and a bottom plate (flange) 34 is formed at its lower end, and a downwardly extending mounting screw 28 is welded to the bottom plate 34. Alternatively, it can be attached by screwing or other methods.

The bottom plate 34 and the mounting screws 28 are also made of conductive metal, but the bottom plate 34 is connected to the cylindrical portion 3 of the cylindrical flange 27.
It is preferable to form it by bending it outward by a 5-dimensional press work or the like.

An inclined groove 36 that is open at the upper end is formed on the circumferential surface of the upper end of the cylindrical portion 35 of the cylindrical flange 270 .

The mounting screw 28 is used to attach the cylindrical flange 27 to the bottom of the case of the electrolytic cell, and at the same time serves as an external terminal when energizing the cathode.

Similar to the case of the cathode 18, the inclined groove 36 is manufactured by protruding outward from the inside of the peripheral wall of the cylindrical portion 350 by pressing or the like.

Incidentally, the inclined groove 36 is inclined downward by an appropriate angle θ with respect to the end surface of the cylindrical portion 35.

(See Figure 2). The width of the inclined groove 36 is equal to the width of the first inclined groove 36 of the cathode 18.
The width dimension is such that the protrusion 32 can freely enter therein.

Next, the operation of attaching and detaching the cathode 18 will be explained.

The protrusion 32 of the cathode 18 is engaged with the inclined groove 36 of the cylindrical flange 27, and the cathode is inserted into the cylindrical portion 35 of the cylindrical flange 27 while being rotated in the direction of arrow A in FIG.

As shown in detail in FIGS. 2 and 3, the cathode 18 is rotated until the end surface 38 of the cylindrical portion 35 and the second protrusion 33 of the cathode 18 come into tight contact. A portion between the inclined groove 36 of the portion 35 and its end face 38 is held by a pair of protrusions 32, 33 of the cathode 18, and is firmly tightened by the wedge action of the inclined groove 36.

In this case, since the first protrusion 32 is engaged with the slope of the inclined groove 36 (FIG. 2) and the circular portion of the second protrusion 330 is in contact with the end surface of the cylindrical flange 27, 3
As shown enlarged in the figure, the contact between the cylindrical flange 27 and the projections 32, 33 of said set is a point contact, which results in a strong clamping action and a complete electrical connection.

When removing the cathode 18, rotating the cathode in the opposite direction disengages the inclined groove 36 and the first protrusion 32, so that the cathode 18 can be easily removed.

In this way, the attachment and detachment of the cathode 18 can be performed with one touch by rotating the cathode by a certain amount,
Moreover, the amount of rotation and the force required for the rotation are determined by the length of the inclined groove 36 and the oblique angle θ, so it can be set arbitrarily and appropriately depending on the size of the cathode, etc. be able to.

In the illustrated embodiment, one inclined groove and a set of protrusions are provided, but a plurality of inclined grooves are formed along the circumferential direction of the cylindrical portion of the cylindrical flange, and the cathode By forming a plurality of sets of protrusions corresponding to the inclined grooves and engaging them with each other, the electrical connection can be made more complete.

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

The key points of this invention are that the two electrodes are concentrically spaced apart without a diaphragm, and it is easy to disassemble and clean, thereby reducing the electrolytic efficiency due to clogging of the diaphragm and the complexity of cleaning the diaphragm. It has the effect of disappearing.
