Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrolytic cell used for a water conditioner or the like for electrolyzing water to produce acidic water and alkaline water.

[0002]

2. Description of the Related Art Conventionally, as an electrolytic cell of this kind, first and second water supply ports are provided at both ends of the bottom of an outer casing formed in a rectangular shape, while the first and second water supply ports are provided at both ends of the top of the outer casing. Two intake ports are provided, and a plurality of anode chambers, each having an anode plate, and a plurality of cathode chambers, each having a cathode plate, are staggered from each other through a diaphragm in the outer casing. Moreover, the anode chamber is formed of a box body for forming an anode chamber formed by combining a pair of rectangular frame bodies provided with a diaphragm, and the cathode chamber is formed with a plurality of boxes for forming an anode chamber. And a second water inlet and a second water inlet while connecting the first water inlet and the first water inlet through the plurality of anode chambers. Through the plurality of cathode chambers and introduced into the casing And water by electrolyzing was something which enables intake of the acidic water and alkaline water.

FIGS. 15 and 16 show the outline of the electrolytic cell X described above. In both figures, the same components are designated by the same reference numerals.

In the figure, 100 is an outer casing, 210 is a first water inlet, 220 is a second water inlet, and 310 is a first water inlet provided at the top of the outer casing at a position facing the first water inlet 210. 1 is a water intake port, 320 is a second water intake port, and 400 and 500 are power supply terminals connected to a cathode / anode plate (not shown).

With the above structure, the first and second water supply ports 210,
The water supplied from 220 is electrolyzed in the tank, and electrolyzed water (acidic water / alkaline water) can be obtained from the first and second intake ports 310 and 320, respectively.

As described above, in the structure in which two water supply ports and two water intake ports are provided, it is easy to individually control the amount of water supply and the amount of water intake. It is easy to mix calcium etc. into the water supply system to the room. Moreover, since the anode chamber and the cathode chamber are formed independently, only ion exchange transfer is performed by electrolysis, and acidic water and alkaline water, which are electrolyzed water, do not mix with each other. It was possible to increase the amount of water intake.

[0007]

However, the above-described conventional electrolytic cell X still has the following problems.

That is, as shown in FIG. 15, in the type in which the first and second water inlets 210 and 220 and the first and second water inlets 310 and 320 are provided so as to face each other in line symmetry, Taking water that has flowed into the tank from the second water supply port 220 as an example, after the water flows from the second water supply port 220 into the anode chamber (cathode chamber), it is electrolyzed to form the second water supply port 220. Water will be taken from the second water intake 320 at the opposite position.

In this case, as shown in the drawing, the water does not evenly pass through the entire anode chamber (cathode chamber), but the second water.
A dead space S where water does not pass will be generated at a portion opposite to the water supply port 220 and the water intake port 320.

Further, as shown in FIG. 16, of the type in which the first and second water supply ports 210 and 220 and the first and second water intake ports 310 and 320 are diagonally opposed to each other in a point-symmetrical manner. In this case, taking water that has flowed into the tank from the second water supply port 220 as an example, water flows into the anode chamber (cathode chamber) from the second water supply port 220 and is then electrolyzed. Water inlet 220
Therefore, water will be taken from the second water intake port 320 which is diagonally located.

Also in this case, as shown in the figure, the water does not evenly pass through the entire anode chamber (cathode chamber), but the water flows near the first water supply port 210 and the first water intake port 310. A dead space S that cannot pass through is generated.

As described above, in any case, efficient electrolysis using the entire electrode plate cannot be performed, which causes a decrease in electrolysis efficiency.

Therefore, an object of the present invention is to solve the above problems and provide an electrolytic cell having a structure in which the advantages of this type of electrolytic cell can be sufficiently brought out.

[0022]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, first and second water supply ports are provided at both ends of one side portion of a rectangular casing, while the first and second water supply ports are provided at both ends of the other side portion facing the one side portion. First and second water supply ports are provided, and inside the same casing are provided electrolytic chambers in which a plurality of anode chambers and a plurality of cathode chambers are alternately partitioned and formed through diaphragms, respectively. An electrolyzer capable of introducing water into the corresponding chambers of the electrolysis chambers from the mouths to electrolyze the water, and taking in water as electrolyzed water from the first and second water intake ports. At least a part of the water supplied from any one of the water supply ports is directed to the other water supply port.

That is, when water is introduced from the first and second water supply ports into the corresponding chambers of the electrolysis chamber, the water does not flow directly into the electrolysis chamber from directly below the water supply port. At least a part of the supplied water is once introduced to the opposite water supply port side and then flows into the electrolysis chamber.

Therefore, unlike the conventional case, the water flowing between the water supply port and the corresponding water intake port in the electrolysis chamber does not become uneven, and passes through the entire electrode plate substantially evenly and uniformly. Therefore, the electrolysis efficiency is remarkably improved, and electrolyzed water can be obtained more efficiently.

Furthermore, since the anode chamber and the cathode chamber are separated and independently configured via the diaphragm, only the ion exchange transfer by electrolysis is performed, and the mixing of acidic water and alkaline water is eliminated, and electrolysis is performed. Water can be taken efficiently. Moreover,
Both chambers have a relatively flat and compact structure, and can be easily installed in a device such as a water conditioner.

As the constitution of the electrolytic chamber partitioned and formed in the casing, a chamber consisting of a box formed by combining a pair of rectangular frame bodies provided with a diaphragm and a space formed outside the box body. And a room consisting of.

With such a simple structure, the anode chamber and the cathode chamber can be partitioned and separated without performing any special processing on the casing.

As described above, in the electrolytic cell according to the present embodiment, the first and second water supply ports are provided at both ends of one side portion of the rectangular casing, while the other side portion facing the one side portion is provided. A plurality of chambers, each of which is a box body formed by combining a pair of rectangular frame bodies provided with a diaphragm in the first and second water intake ports on both end sides, and the outside of the box body. An electrolysis chamber in which a plurality of chambers formed in the space are alternately arranged is provided, and water is introduced from the first and second water supply ports into the corresponding chambers of the electrolysis chamber for electrolysis. ,
The electrolysis water can be taken in through the first and second intake ports.

In such a configuration, "at least a part of the water supplied from one of the first and second water supply ports,
In order to guide the water toward the other water supply port side, the following configuration can be used, for example.

That is, the first water supply port and the first water intake port communicate with each other through the insides of the plurality of boxes, and
The second water supply port and the second water intake port are communicated with each other through a chamber formed of a space formed outside the box body,
A tubular communication part connected to the first water supply port is provided in a protruding manner on the box body, and a water guiding amount adjusting means is provided between an end surface of the box body provided with the communication part and an inner wall surface of the casing. Is formed to guide at least a part of the water supplied from the second water supply port to the water guide path toward the communication section side.

Further, the water guiding amount adjusting means is composed of a gap portion having a predetermined width, which is formed at the overlapping portion of the end face edges of the plurality of boxes, and the gap portion is formed in the vicinity of the cylindrical communicating portion. Can be configured.

At this time, as long as a plurality of box bodies are arranged so as to overlap each other without any particular seal between the box bodies, and when the plurality of box bodies are stored and arranged in a state of being simply inserted into the casing. Even more so, there is a slight gap between the boxes. There is also a gap between the box and the casing.

In the present embodiment, apart from the small gap (overlapping portion of the end face edges of the box body), a gap portion wider than the small gap is formed in the vicinity of the communication portion, and the second gap is formed. The water that has flowed in from the water supply port at a predetermined water pressure slightly expands the small gap portion and flows into the electrolysis chamber, and also flows into the electrolysis chamber from the gap between the box body and the casing. On the other hand, part of the water introduced toward the communication part side flows into the electrolysis chamber from a rather wide gap with the water pressure lowered, and as a result, flows almost uniformly in the entire width direction of the electrolysis chamber. As a result, the entire electrode plate is evenly contacted, and the electrolysis efficiency can be improved.

Further, as another embodiment of the water guiding amount adjusting means, the gap portion may be gradually widened toward the tubular communicating portion side.

With this structure, the water introduced from the second water supply port can be made to flow substantially evenly in the width direction of the electrolysis chamber in the same manner as described above.

Further, in the present embodiment, the chamber consisting of the box body is used as an anode chamber, the chamber consisting of a space formed outside the box body is used as a cathode chamber, and acidic water is supplied from the first water intake port. It is possible to take alkaline water from the second water intake.

Further, the first and second water inlets are provided at both ends of the bottom of the casing, while the first and second water inlets are provided at both ends of the top of the casing.

That is, since the water flows into the casing from the lower side, it rises while sufficiently filling the inside of the casing, the contact area with the electrode plate and the contact time are also sufficient, and the electrolysis is efficiently performed to cause the casing. The required amount of water can be taken from above.

On the other hand, in the above-mentioned structure, it is desirable to carry out water introduction adjustment also on the intake side in the casing.

That is, the water flowing in from the first water supply port is electrolyzed and flows out from the first water intake port, while the water flowing in from the second water supply port is electrolyzed and flows out from the second water intake port. In this case, the end face of the box body facing the first and second intake ports is gradually narrowed from the vicinity of the position where the first intake port is provided toward the position where the second intake port is provided. To be formed.

With this configuration, on the intake side, the gap formed between the plurality of boxes is, on the contrary, gradually widened from the first intake side toward the second intake side. Therefore, as described above, the water that has flowed in from the second water supply port passes evenly through the entire cathode chamber, and finally flows out efficiently from the second water intake port. Therefore, the water intake efficiency is improved.

It is desirable that the inside of the box has the following structure.

That is, a water guiding amount adjusting wall for guiding the inflowing water is formed inside the box, and moreover, the water guiding amount adjusting wall is
The elongated holes are formed so as to gradually widen as they are separated from the water inflow side.

With this structure, water can evenly pass through the anode chamber formed in the box in the same manner as the above-described passage of water in the cathode chamber.
It is possible to improve the electrolysis efficiency of the entire electrolytic cell.

As shown in FIGS. 2 and 3, the box body 2 is formed by joining a pair of flat rectangular frame bodies 2a and 2b in an opposed state, and both frame bodies 2a and 2b. An anode plate 3 is provided between them to make the whole thin. Reference numeral 20 is a guide groove for projecting the feeding terminal 3a from the box body 2 to the outside.

The frame bodies 2a and 2b are a rectangular outer frame 21 including an upper frame 21a, a lower frame 21b, and left and right side frames 21c and 21d, respectively.
Between the left and right frames 21c, 21d, five thin vertical ribs 22 are provided at relatively small intervals in the width direction, and the diaphragm 6 is formed. As shown in FIG. 6, the diaphragm 6 is formed by the vertical ribs. It is integrally formed with 22 by injection molding. Further, as compared with the conventional diaphragm supporting structure, since the diaphragm 6 is supported by a relatively large number of vertical ribs 22, the diaphragm 6 does not loosen, and the sturdy box body 2 is configured.

It can be supported in a state where water can flow smoothly. Although not shown, the cathode plate 4 can also be held between the boxes 2 or at a position outside the boxes 2 without hindering the flow of water by the small protrusions 22a. Similarly, water can flow smoothly.

When the box body 2 is formed by coupling both the frame bodies 2a and 2b to one side of the lower edges of the frame bodies 2a and 2b,
The first cylindrical shape that communicates with the anode chamber formed inside the box body 2
Along with projecting half-split cylinder portions 23a, 23b forming the communication portion 23, on one side of the upper end edge facing the half-split cylinder portions 23a, 23b,
A second communicating part communicating with the first water intake 13 provided in the upper case 1b
Half-split cylinder portions 24a and 24b forming 24 are provided in a protruding manner.

The first communicating portion 23, as shown in FIG.
The water is fitted into the water supply port 11 via the packing 25, and all the water flowing in from the first water supply port 11 is introduced into the anode chamber (inside the box body 2). Although not shown, the second communication portion 24 has the same structure as the first communication portion 23.
All the water flowing out from the communication part 24 flows out from the first water intake 13.

As described above, in the electrolytic cell A according to the present embodiment, the first and second water supply ports 11 and 12 are provided at both ends of the bottom portion of the outer casing 1, while both ends of the top portion of the outer casing 1 are provided. The water inlets 11 and 12 are respectively provided with first and second water intakes 13 and 14 which are line-symmetrical to each other, and the outer casing 1 has two box bodies 2 each having an anode plate 3 disposed therein.
And the three cathode chambers, each of which is provided with the cathode plate 4, are alternately formed with the diaphragm 6, and the first water supply port 11 and the first water intake port 13 are formed. The second water supply port 12 and the second water intake port 14 are configured to communicate with each other through the anode chamber and the cathode chamber.

With this structure, by introducing water into the outer casing 1 through the first and second water supply ports 11 and 12 and electrolyzing it, acidic water is discharged from the first water intake port 13 and second water intake port 14 is discharged.
It is now possible to take alkaline water from.

In the electrolytic cell A having the above structure, the feature of this embodiment is that the water supplied from the second water supply port 12 is
In the outer casing 1, water is introduced toward the first water supply port 11 side.

In the present embodiment, as shown in FIG. 9, between the lower wall end surface 26 of the box body 2 provided with the first communication portion 23 projecting and the lower wall inner side surface (inner wall surface) of the outer casing 1. A water channel 7 communicating with the cathode chamber is formed, and the water channel 7 is provided with a water quantity adjusting means, and the water supplied from the second water inlet 12 to the water channel 7 is the first water inlet. The water is guided toward the 11th side, and a large amount of water is adjusted by the means for adjusting the amount of water to be introduced into the cathode chamber from the first water supply port 11 side rather than the second water supply port 12 side.

As shown in FIG. 10, the water guiding amount adjusting means is composed of a gap portion 70b having a predetermined width, which is formed at the overlapping portion between the end face edges of the two boxes 2, 2, and the gap portion 70b is ,
It is formed in the vicinity of the first communication portion 23.

That is, in this embodiment, the box 2 and the box 2 are
Between the box body 2 and the box body, the box body 2 and the box body are arranged so as to be overlapped with each other without a seal or the like, and moreover, the box bodies 2 and 2 are accommodated in the outer casing 1 in a state of being simply inserted. A small gap 70a is formed between the two. Moreover, since the box body 2 is formed in a flat shape, the box body 2 itself is bent by water pressure, so that the small gap 70a is more easily formed between the box bodies 2 and 2. In addition, a gap 7 is naturally formed between each box 2 and the inner surface of the outer casing 1.
There will be 0 '.

In the present embodiment, in addition to the small gap 70a (formed in the overlapping portion 70 between the end face edges of the box body), in the vicinity of the first communicating portion 23, the width is wider than the small gap 70a. The gap 70b is formed, and the water flowing in from the second water supply port 12 at a predetermined water pressure pushes the small gap 70a slightly to flow into the cathode chamber.
A gap 70 'between the inner surface of the outer casing 1 and the inner surface of the outer casing 1 also allows the gas to flow into the cathode chamber. On the other hand, headrace 7
As a result, a part of the water introduced toward the first communication portion 23 side flows into the cathode chamber from the slightly wide gap 70b in a state where the water pressure is reduced, and also the box 2 and the outside. Between the inner surface of the casing 1 (lower case 1a), there is a gap from the position of the electrode 4a of the cathode plate 4 to the first communication portion 23.
70c is formed, and water also flows into the cathode chamber from the gap 70c. As a result, as shown by the arrow in FIG. 13, the water flowing in from the second water supply port 12 passes evenly through the entire flat cathode chamber, and efficient electrolysis is performed by the entire cathode plate 4. Water can be taken from the second intake port 14,
In the electrolytic cell A according to this example, the electrolysis efficiency can be improved.

Further, as a modification of the water quantity adjusting means, the structure shown in FIG. 11 may be adopted.

That is, a small gap 70a 'which is slightly wider than the small gap 70a shown in FIG. 10 is formed in the overlapping portion 70 between the lower wall edges of the two boxes 2, 2 and the same. Small gap
70a 'is formed from the second water supply port 12 side to the position of the electrode 4a located closer to the first communicating portion 23 side than the center, and gradually widens from the position of the electrode 4a to the position reaching the first communicating portion 23. The gap 70b 'is formed so that Similarly, as shown in FIG. 11, between the box body 2 and the inner surface of the outer casing 1 (lower case 1a), the distance from the position of the electrode 41 of the cathode plate 4 to the first communication portion 23 gradually increases. A widening gap 70c 'is formed so that water can smoothly flow into the cathode chamber.

Also in this structure, the water flowing into the water conduit 7 from the second water supply port 12 does not directly flow into the cathode chamber as it is, but a narrow small gap is provided immediately above the second water supply port. Since 70a 'exists, it seems as if it collided with the wall and the flow path was forcibly changed in a substantially perpendicular direction.
The small gap 70a 'and the gap portion 70b' flow toward the communication portion 23 side (the first water supply port 11 side) and the water pressure gradually weakens.
Spread and flow into the cathode chamber.

Therefore, even with the above structure, a substantially uniform flow of water can be realized in the cathode chamber as shown in FIG.
It is possible to improve the electrolysis efficiency.

Further, as one of the features of the electrolytic cell A according to this embodiment, the upper wall end surface 2 of the box body 2 on the side of the water intake (13, 14)
As shown in FIG. 12, 7 is formed to have a gradually narrower width from the first water intake 13 side toward the second water intake 14 side.
That is, the side edges of the upper frame 21a of the frame bodies 2a and 2b forming the box body 2 are formed into tapered surfaces.

Therefore, the space formed between the two box bodies 2, 2 and the box body 2 and the outer casing 1 (the upper case 1
On the contrary, the gap formed with b) gradually widens from the side of the first water intake 13 toward the side of the second water intake 14 and flows in from the second water supply port 12 to the entire cathode chamber. The water flowing substantially evenly is efficiently collected to the second intake port 14 side as shown in FIG. 13, and the intake efficiency can be improved.

Further, in the present embodiment, the flow of water is also uniform in the anode chamber.

That is, as shown in FIG. 8, at the inner lower part of the box body 2 forming the anode chamber, it has flowed into the position just above each lower frame 21b of the frame bodies 2a and 2b from the first communicating portion 23. When a transverse wall 28 for receiving water is provided (see FIG. 3), the surface portion facing the inside of the transverse wall 28 is formed into a tapered surface, and the frame bodies 2a and 2b are butted against each other to form the box body 2, the transverse wall 28 , 28 are butted against each other to form a water guiding amount adjusting wall 29 (FIG. 4), and the water guiding amount adjusting wall 29 has an elongated shape gradually widened as it is separated from the first communicating portion 23 by the above-mentioned tapered surface. Hole 30
Are formed.

Therefore, the inflowing water flows into the first communicating portion 23.
A greater amount of water is introduced to the anode plate 3 side from a location farther from.

Further, as shown in FIG. 7, a second water guiding amount adjusting wall 31 is formed immediately above the water guiding amount adjusting wall 29.

Also in this case, the second transverse walls 32, 32 are formed above the transverse walls 28 of the frame bodies 2a, 2b (see FIG. 3), and the frame bodies 2a, 2b are butted against each other to form the box body 2. It is formed when configured, and as shown in FIG. 7, the surface portion facing inward is cut and formed, and the first communication portion 23 side is made thinnest,
A long flow passage 33 is formed so that the narrowest portion to the electrode 3a is wide and the tip from the electrode 3a is a middle thin portion.

Further, as shown in FIG. 5, a third water guiding amount adjusting wall 34 is formed immediately below the upper wall end surface 27 of the box body 2.

The third water guiding volume adjusting wall 34 is composed of the frames 2a, 2b.
A cross wall 35 for receiving the water that has passed through the anode chamber is provided at a position directly below each upper frame 21a (see FIG. 3).
When the surface portion facing the inside of 35 is a tapered surface and the frame bodies 2a and 2b are butted against each other to form the box body 2, the transverse walls 35 and 35 are butted to form the third water quantity adjusting wall 34. Further, the third water guiding amount adjusting wall 34 is provided with the elongated hole 36 which is gradually widened toward the second cylindrical communicating portion 24 by the above-mentioned tapered surface.

Furthermore, since the anode chamber and the cathode chamber are separated and independent of each other via the diaphragm 6, only ion exchange transfer by electrolysis is performed, and mixing of acidic water and alkaline water is eliminated. The electrolyzed water can be taken in efficiently.

Therefore, the electrolytic cell A is compact and has excellent electrolysis capacity, and is most suitable for applications such as water conditioners.

11,12 and the first and second intake ports 13,14 are the outer casing 1
The first and second water supply ports 11 and 1 and the first and second water intake ports 13 and 14 are arranged substantially diagonally symmetrical to each other on a diagonal line. It can also be applied to those provided facing each other, and even in this case, as shown in FIG. 14, a substantially uniform flow of water can be realized in the cathode chamber, and the dead space does not occur in the cathode plate 4 and Since they come into uniform contact with each other, it is possible to improve the electrolytic efficiency.
