Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an ozone generator that generates ozone and ions by a discharge action using a pair of electrodes.

(Prior Art) Conventionally, as a means for generating ozone using a discharge electrode, for example, as described in Japanese Utility Model Publication No. 60-24351, a discharge electrode formed in a predetermined shape such as a flat plate or a tube shape is used. There is one in which two pieces are arranged facing each other in a predetermined position.

Another method, as described in Japanese Patent Publication No. Sho 61-29882, is to form the entire device into a so-called Shirotsuko-type blower type, with a rotating blade as one electrode and the other electrode as the rotating blade. There are some that are placed facing each other.

(Problems to be Solved by the Invention) However, with the former conventional means, since a pair of electrodes are always fixed at a predetermined position, the following problems occur. was.

In other words, when installing a pair of electrodes, it is necessary to set the distance between them uniformly over the entire area, but in reality, some error occurs in this installation dimension, and it is necessary to set both electrodes completely parallel. It is difficult to set the state. Further, even if both electrodes are set in a highly accurate parallel state, since there are some irregularities on the surface, it is extremely difficult to set the mutual distances between both electrodes equally at various locations. Therefore, if discharge is performed under these conditions, both electrodes 4,
Intensive discharge occurs at the shortest distance position B of 4a, and the area B generates heat to an abnormally high temperature.

However, it is well known that in this type of ozone generation work, if the electrode becomes hot, the generated ozone will be immediately decomposed. Then,
In the past, the ozone generation efficiency decreased and it was difficult to generate ozone efficiently, which caused a fatal problem. Although this problem can be solved to some extent by cooling the electrodes themselves or the gas supplied between the electrodes, this requires a separate cooling device, which increases the size and cost of the device. It happens.

In addition, with the above-mentioned conventional device in which both electrodes are fixed, dust such as dust adheres and accumulates on the surface of both electrodes, and the hydrogen compounds formed thereby further reduce the ozone generation efficiency. It also had

On the other hand, with the conventional rotary type of rear housing, the adhesion of dust to the electrode surface is eliminated, and even if there is some error in the parallel spacing of the electrode surface, locally concentrated discharge is avoided. You can get the benefits that you can. However, in this method, in order to rotate one of the electrodes, a power supply brush is required to supply power to the electrode, and it becomes troublesome to replace parts due to wear of the brush, which causes problems in maintenance management. It was causing problems. Furthermore, in order to maintain both electrodes facing each other at all times in the conventional means, it is necessary to form one of the electrodes to be rotated into a cylindrical or disk shape. Therefore, the electrode becomes larger than necessary,
This also poses a disadvantage in reducing the size of the device.

Therefore, the present invention eliminates the need for power supply brushes, which are troublesome to maintain, and simplifies the device configuration.
The purpose is to enable miniaturization, suppress locally concentrated discharge caused by irregularities on the electrode surface, and the adhesion of dust to the electrode, and increase the efficiency of generating ozone, etc. It is.

(Means for Solving the Problems) The present invention solves the above-mentioned problems by adopting a method of moving the electrodes that has not been seen in the past, instead of simply providing fixed electrodes or rotating them as in the past. The aim is to eliminate the In addition, the present invention can be used as a means to promote miniaturization of the entire device.
This arrangement is designed so that the movement of the electrode and the operation of the pump for supplying gas are performed by one driving source.

That is, firstly, the present invention allows at least one electrode 4a of a pair of discharge electrodes 4, 4a provided facing each other to be moved along a direction intersecting the opposing direction of both electrodes 4, 4a. This is a generator of ozone, etc., which is provided so as to be reciprocally movable, and configured so that the opposing positions of the opposing surfaces 20, 20a of the electrodes 4, 4a move relative to each other.

As a device included in the above configuration, the present invention has the following features:
The electrode 4a on one side is supported by a support 7 which is provided so as to be able to swing back and forth, and by the swinging motion of the support 7 about the swing fulcrum A, it can be moved in the opposite direction to the other electrode 4. The opposing surfaces 20, 20a of the electrodes 4, 4a are provided to swing back and forth along the intersecting directions.
This is a generator of ozone, etc., which is formed into an arc shape with the swing fulcrum A of the support body 7 as the radial center, and is set in a mutually parallel state.

In addition, as another aspect of the present invention, one electrode 4a is supported by a support 7a that can reciprocate in parallel with the opposing surface 20 of the other electrode 4, and the reciprocating movement of the support 7a causes the one electrode 4a to Electrode 4a is the other electrode 4
This is an ozone generator, etc., which is installed to be able to move back and forth while maintaining a parallel state with the

Second, the present invention provides an apparatus having each of the above configurations.
A pump 11 for supplying gas between the electrodes 4 and 4a is provided separately from the electrodes 4 and 4a.
By connecting the actuating body 13 to the support body 7 that supports the electrode 4a in a reciprocating manner, the actuating body 13
This is an ozone generating device configured so that the pump 11 can be operated by driving in conjunction with the reciprocating movement of the support body 7.

(Function) In the device configured as described above, since the opposing positions of the resistance surfaces 20 and 20a of both electrodes 4 and 4a can be relatively moved when causing discharge between both electrodes 4 and 4a, Even if there are unevenness etc. on each opposing surface 20, 20a and the mutual dimensions are uneven,
This makes it possible to appropriately prevent discharge from occurring concentrated in the same specific location. Therefore, electrodes 4, 4
There is no abnormally high temperature region in electrode 4, which would cause a decrease in the production efficiency of ozone, etc.
A discharge action effective for generating ozone etc. can be appropriately performed over a wide area of each opposing surface 20, 20a of 4a.

Thus, each of the opposing surfaces 20, 2 of the electrodes 4, 4a
Since the relative movement of 0a is performed by reciprocating movement of both or one of the electrodes 4, 4a, there is no need to use a power supply brush when supplying power to the reciprocating electrode 4a. This can be achieved by simply wiring a cord without causing problems such as wear and tear. In addition, since the electrode 4a is moved back and forth in a direction that intersects the facing direction of both electrodes, it is not necessary to form either one of the electrodes into a large-diameter disk shape or a ring shape. , 4a, for example, small-sized flat electrodes can be used as appropriate.

Furthermore, each opposing surface 20, 20a of both electrodes 4, 4a
According to a method in which electrodes 4a are formed into predetermined circular arc shapes parallel to each other, and one of the electrodes 4a is supported and swung by a support 7 that can swing back and forth, the electrode 4a moves in a circular shape by the swiveling action. Although the electrodes 4, 4a swing in an arcuate trajectory, the distance between the opposing surfaces 20, 20a of the electrodes 4, 4a is always maintained at a constant value. Therefore, the problem of unduly changing the mutual distance between the two electrodes due to the reciprocating movement of the electrode 4a is eliminated. In addition, when the electrode 4a is supported by a support 7a that reciprocates in parallel with the facing surface 20 of the other electrode 4 and reciprocates in the same direction, the facing surfaces 20, 20a may be formed in an arc shape. However, the same effect as described above can be obtained.

Furthermore, the gas supply pump 1 of the second configuration
In the case where the first actuating body 13 and the support body 7 are connected, a dedicated drive source for the pump 11 is not required. or,
Since the pump 11 is constructed separately from the electrodes 4 and 4a, its gas blowing function is not subject to major restrictions as would be the case if the electrodes were integrated into a blower.
It becomes possible to set the gas supply pressure and supply amount to desired required values as appropriate.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

[First Embodiment] In FIG. 1, 1 indicates a casing provided with an air supply port 2 and an air exhaust port 3, respectively. Reference numerals 4 and 4a denote a pair of substantially flat discharge electrodes 4 disposed at predetermined positions in the casing 1 and facing each other in an insulated state.
4a, the lower electrode 4 is provided in a fixed state, and its opposing surface 20 is covered with a dielectric 5. On the other hand, the upper electrode 4a is set to have a smaller area than the lower electrode 4, and is attached in an insulated manner to the lower part of a support body 7 which is provided to be swingable from side to side about a shaft 6 as a fulcrum. Also, the opposing surfaces 20, 20a of both electrodes 4, 4a and the surface of the dielectric 5 have a radius of curvature centered on the swing fulcrum A of the support 7, as shown in FIG.
R ₁ , R ₂ , and R ₃ are formed into convex or concave arc-shaped curved surfaces. Reference numeral 17 indicates the voltage of the potential difference required for corona discharge between the discharge electrodes 4 and 4a through the cable 1.
8, 18a.

Reference numeral 10 indicates a permanent magnet attached to the upper part of the support 7. Reference numeral 8 denotes a solenoid coil disposed facing above the permanent magnet 10, which forms an alternating magnetic field in which the direction of the magnetic field and the electrodes are alternately switched by supplying power from an AC power source 9 such as a commercial power source. This is for reciprocating the support body 7 provided with the permanent magnet 10 to the left and right in a predetermined cycle.

Reference numeral 11 denotes a pump for supplying gas, which is connected to the air supply port 2 of the casing 1 through piping and installed on the side of the support 7. Intake port 14
Both the electrodes 4, 4 are connected by sucking air from the atmosphere from the side
This is for supplying air between a. 15,
15a is a check valve. 16 is a reciprocating rod whose one end is connected to the diaphragm 13 of the pump 11, and the other end is connected to the support 7.
The diaphragm 13 is connected to the support body 7 so that the diaphragm 13 is reciprocated by the reciprocating swinging motion of the diaphragm 13.

Since the present embodiment has the above-described configuration, first of all, if the support body 7 equipped with the permanent magnet 10 is reciprocated by the alternating magnetic field of the solenoid coil 8, the upper electrode 4a is connected to the lower electrode 4. It swings back and forth from side to side while maintaining the facing state.

In this state, each opposing surface 2 of both electrodes 4, 4a
The facing positions of 0 and 20a are continuously changed, and the situation where the same parts always face each other is eliminated. Therefore, even if the electrodes 4, 4a are not completely parallel, and even if there are some irregularities on their opposing surfaces, concentrated discharge will not occur at the same location. Appropriate discharge occurs at various locations between both electrodes 4 and 4a, and the occurrence of locally abnormally high temperature areas is eliminated. the result,
Ozone generated by the discharge action between the electrodes 4, 4a does not decompose immediately due to high heat.

In addition, since the facing surfaces 20, 20a of each electrode 4, 4a are formed in an arc shape centered on the swing fulcrum A of the support 7, when one electrode 4a swings to any position, However, both electrodes 4 and 4a maintain a parallel state, and the distance between them is always maintained at a constant value. Therefore, the discharge effective for ozone generation is carried out over a wide area over the entire surface or substantially the entire surface of both electrodes 4, 4a, and the ozone generation efficiency becomes even better. Furthermore, since the adhesion of dust to the side of the electrode 4a that performs the swinging operation is considerably prevented, the reduction in ozone generation efficiency caused by the adhesion of dust is also halved.

Furthermore, power is supplied from the transformer 17 to the upper electrode 4a by a simple wiring connection, similar to the fixed electrode 4 side, but since the upper electrode 4a simply performs reciprocating motion, the wiring connection is not necessary. It is possible to deal with the problem with just one, and there is no need to use a power supply brush or the like with a complicated structure.

On the other hand, since the drive rod 16 of the pump 11 is connected to the support body 7, the pump 11 can be operated in conjunction with the left and right swinging motion of the support body 7. Air necessary for generation can be forcibly supplied between both electrodes 4, 4a.
Since the pump 11 does not require its own drive source, the overall structure of the device can be simplified and downsized. In addition, since the pump 11, which is configured separately from the electrodes 4, 4a, etc., can appropriately set its compression ratio, etc., the amount and pressure of air supplied to the electrodes 4, 4a can be adjusted to desired and necessary values. It also provides flexibility in settings.

In the above embodiment, each of the opposing surfaces of the electrodes 4 and 4a is formed into a predetermined arcuate curved surface so that the opposing surfaces are always maintained in a parallel state. , 4a need not be formed into curved shapes. If the distance from the swing center position 6 of the support body 7 to the mounting position of the electrode 4a is large,
Since the fluctuation value of the distance dimension between the electrodes 4, 4a caused by the swinging of the electrode 4a becomes small, if the fluctuation value is within a small range that does not hinder the discharge action, the electrodes 4, 4a may be opposed to each other. This is because there is no problem even if the surface is made flat.

[Second Embodiment] Next, a second embodiment will be described with reference to FIG.
However, for convenience of explanation, the same reference numerals as in the first embodiment shown in FIG. 1 indicate the same members and equipment in the figure.

In the figure, reference numeral 7a denotes a support for supporting one electrode 4a of the two electrodes 4, 4a disposed facing each other in the casing 1; It is provided so that it can reciprocate in parallel. Reference numeral 10a denotes a permanent magnet attached to the support 7a, which is provided at a position facing a separately provided solenoid coil 8 for forming an alternating magnetic field, and by forming the alternating magnetic field of the coil 8, the support 7a is turned into an electrode. It is designed to be able to freely reciprocate in parallel with the opposing surface 20 of No. 4. 11a is a piston 13 in a cylinder 13;
A gas supply pump fitted with a (actuating body),
One end of the support 7a is connected to the piston 13a to perform a pumping action by reciprocating the support 7a.

In the device configured as described above, similarly to the first embodiment, by simply forming an alternating magnetic field with the solenoid coil 8, the pump 11a is operated to supply the air necessary for ozone generation between the electrodes 4 and 4a. The electrode 4a can be forcibly fed into the interior of the body, and can be reciprocated with one electrode 4a facing the other electrode 4.

In this means, in order for one electrode 4a to move parallel to the opposing surface 20 of the other electrode 4a, it is not necessary to form each opposing surface 20, 20a of both electrodes 4, 4a into an arc shape. By maintaining the mutual distance between the planar opposing surfaces 20 and 20a at a desired constant dimension, it is possible to generate a discharge effect effective for ozone generation over a wide area on each opposing surface of the electrode. . Also, as in the first embodiment, locally concentrated discharge does not occur between the electrodes 4 and 4a.

[Other Examples]

In each of the above embodiments, the electrode 4 on one side is
Although only a is reciprocated, the present invention is by no means limited to this. There is no problem even if both of the pair of electrodes 4, 4a are moved back and forth. In this case, it is possible to prevent dust from adhering to both electrodes 4 and 4a, and it is possible to suppress the decrease in ozone generation efficiency caused by dust adhesion to a greater extent than in the above embodiments.

To reciprocate both electrodes 4, 4a at the same time,
For example, as shown in FIG. 4, means may be adopted as appropriate, such as attaching the electrodes 4, 4a to two supports 7b, 7c attached to shafts 30, 30a, respectively. In this mechanism, connecting rods 31, 31a are connected to each shaft 30, 30a.
The alternating magnetic field of the solenoid coil 8a may be applied to the permanent magnets 10b, 10c connected via the permanent magnets 10b, 10c to swing the electrodes 4, 4a in mutually different directions.

In the present invention, the positions of both electrodes 4 and 4a are changed relative to each other, so when both electrodes 4 and 4a are moved, their moving directions and speeds may be set to be different. .

Furthermore, in the present invention, the specific configuration of each part such as the electrodes 4, 4a, the support means for supporting them, and the drive means for reciprocating the electrodes 4, 4a is not limited as described above; All specific configurations can be freely modified within the scope of the present invention. Although the present invention has the advantage that both electrodes can be formed into small flat plate shapes, the present invention is not necessarily limited to this, and can also be applied to cases where cylindrical electrodes are used. Also, a pump 1 for gas supply
1, various types of pumps other than the above-mentioned embodiments can be applied, and furthermore, it is not necessarily necessary to use a combination means of a permanent magnet 10 and a solenoid coil 8 as means for reciprocating the supports 7, 7a.

In addition, the present invention is not limited to the use of generating ozone, and since ions can also be generated using the same discharge principle, it may of course be applied as an ion generator.

(Effects of the invention) As described above, the present invention provides a pair of discharge electrodes that is capable of reciprocating in a direction that intersects with the direction in which the two electrodes face each other. Since the opposing positions of the electrodes are constructed so that they can be moved relative to each other, even if there are irregularities on the opposing surfaces of the electrodes and the dimensions between them are uneven, it is not possible to keep the two electrodes fixed in a conventional manner. Unlike other methods, it is possible to eliminate the abnormal temperature rise of the electrode without causing discharge concentrated at the same point, and it is possible to suppress the adhesion of dust to the electrode. Power can now be supplied to the electrodes by simple cord wiring, similar to fixed electrodes, without the need to use a power supply brush with a complicated structure as in conventional rotating electrodes.

As a result, according to the present invention, the production efficiency of ozone, etc. can be significantly increased compared to the conventional case where both electrodes are fixed. This has resulted in the special effects of being able to eliminate the hassle of complicated parts replacement, etc., making it superior in terms of maintenance and management, and greatly increasing its practicality.

In addition, with the present invention, there is no need to form one electrode in a disk shape or a ring shape in order to always face both electrodes as in conventional means for rotating electrodes, and both electrodes have a small flat plate shape. There is also the advantage that things can be used as appropriate.

Furthermore, when one electrode of the present invention is oscillated, the opposing surfaces of both electrodes may be formed into parallel arcuate surfaces centered on the center of oscillation of the electrode, or one electrode may be oscillated by the other electrode. By means of supporting a support body that reciprocates in parallel with the opposing surface and reciprocating in the same direction, the distance between the two electrodes can be maintained at a constant value at all times, and the opposing surface of the two electrodes Effective discharge work can be continued over a wide area over the entire surface or substantially the entire surface, and there is an effect that the generation efficiency of ozone, etc. can be further improved.

Furthermore, according to the method of the present invention in which a pump for gas supply is provided separately and the actuating body of the pump is connected to the supporting body, there is no large restriction on the amount and pressure of the gas blown as in the case where the electrode is integrated with the blower. In addition to providing flexibility in setting the conditions for gas supply, there is no need for a dedicated drive source for the pump, which has the practical benefit of simplifying and downsizing the entire device.

Furthermore, with the method of the present invention in which the reciprocating motion of the electrode is performed by a combination of a permanent magnet and a solenoid coil for forming an alternating magnetic field, the structure is extremely simple, and the device can be further miniaturized, and its operation is reliable. It has excellent advantages in various aspects such as high performance and maintenance.
