Description

  The present invention relates to an electrostatic field generator that forms an electrostatic field barrier with an electrostatic field generator. In addition, a flying organism removing device that charges and traps or repels flying organisms such as pests, mold spores, and fungi using the electrostatic field generating device, and further uses an electrostatic field generating device to create an internal space. The present invention relates to a plant protection device that has a plant growing environment and can prevent the occurrence of plant diseases and insects.

There is a need to avoid flying insects such as flying insect pests, floating mold spores, and fungus bodies in facilities as a growing environment for facility cultivation and in living rooms as living environments. If these flying organisms enter the facilities or living rooms, there is a possibility that diseases and insect damage will spread to the plants, and insects may be infested and diseases may occur.
Conventionally, measures have been generally taken to apply and spray chemicals such as insecticides, insecticides, fungicides, and fungicides.

  However, in recent years, due to the heightened safety awareness, the use of pesticides on agricultural crops and pesticide-free cultivation have become popular, and there is a demand for measures against diseases and pests that are effective without using pesticides or with small amounts. . In addition, regarding the dwelling, both insecticide sprays that fill the room and insecticide sprays that are applied to the human body are becoming increasingly repelled due to the risk of chemical damage and the like because the drugs can be absorbed by the human body.

Therefore, in recent years, flying organism removal devices using electrostatic screens and plant protection devices using electrostatic screens have attracted attention as repelling means for pests, mold spores and fungus bodies that do not use drugs. .
An electrostatic field generator is a device that applies a DC high voltage to a metal conductor, generates static electricity on the surface of the insulator covering the electrodes, and traps charged insects, dust, etc. with the insulator due to the electrostatic force. Say. FIG. 12 is a diagram for briefly explaining the structure of a conventional electrostatic field generator. As shown in FIG. 12, the electrostatic field generator 10 includes an electrode group 11 in which a dielectric coating covered with a dielectric made of an insulating resin is arranged in parallel at intervals of several millimeters to several centimeters, and a positive potential applying a positive potential. It is composed of a potential applying device 12, a negative potential applying device 13 that applies a negative potential, and a ground electrode 14. Here, the electrode group 11 is referred to as an “electrostatic catcher”.
The earth electrode 14 plays a role of preventing contact of the human body with the electrostatic catcher 11, protecting the electrode, and restricting (repelling action) pest adhesion, and an electrostatic field is generated between the dielectric coverings of the electrostatic catcher 11. To do. Insects, dust, and the like that have entered the electrostatic catcher 11 are charged, and are attracted to and captured by the electrostatic catcher 11 with a strong Coulomb force.

The inventor of the present application has proposed an invention relating to the following patent document regarding the electrostatic field generator 10.
The invention according to Patent Document 1 captures and removes spores of plant pathogenic bacteria that cause plant disease or insect damage by applying force by an electrostatic field to flying organisms such as fungus bodies and small pests, or the removal thereof It is intended to provide a flying organism removing device and a plant protection device for preventing the occurrence of plant disease and insect damage by killing the flying organisms by discharging them even if they are escaped. .

  The invention according to Patent Document 2 can protect both the ground exposed part and the ground non-exposed part of a plant with a single device, and can be handled safely and easily. A device is provided.

  The invention according to Patent Document 3 is an apparatus that can maintain a charged state and obtain a high capture power that does not depend on humidity, such as spores or fungus bodies of phytopathogenic fungi that cause plant pest damage, An electrostatic field generator that exhibits trapping or repelling effects on flying organisms, is capable of long-term operation with less clogging, improved air permeability, and is thin and safe. And the flying organism removal method using the same is provided. The invention according to Patent Document 4 is capable of efficiently removing conidia and fungi of phytopathogenic bacteria from the air, and that there is no ozone generation due to electric discharge, etc. A method that can be prevented is provided.

Thus, although this inventor has proposed the above invention about an electrostatic field generator, it can classify | categorize roughly into two.
The first is a case where the electrostatic catcher is monopolar. In the case of a single pole, in the prior art, an electrostatic catcher and a ground electrode grounded to the ground are indispensable, and an electrostatic catcher and one ground electrode, or an electrostatic catcher and two ground electrodes on both sides thereof are arranged. There was a configuration example. In addition, in order to drive a positive or negative voltage application device having a DC type booster with a battery, it is essential to ground the negative terminal of the battery to ground.
The second is a case where the electrostatic catcher is bipolar. In the case of two poles, the positive electrode and the negative electrode are alternately arranged. In this case, the ground electrode is not particularly required for the electric field configuration. However, in order to drive the positive and negative voltage application devices with a battery, it is essential to ground the negative terminal of the battery to ground. Further, in order to ensure safety, it has been desired to arrange the ground electrode on one side or two sides (on both sides) for controlling adhesion of insects or the like to the electrostatic catcher portion.

  One of the specific uses of the electrostatic field generator is to provide an electrostatic field generator on the walls and entrances of greenhouses and greenhouses, etc., and to provide a repelling function for pests, mold spores, and fungus bodies to the crop fields inside. It is. The inventor of the present application has continued development to apply electrostatic field generators to the walls and entrances of greenhouses and greenhouses, etc. When applying these electrostatic field generators, the electrode group 11 is still several thousand volts. Since it is necessary to apply a high voltage, the arrangement of the ground electrode 12 is an indispensable measure in order to ensure the safety against the electric shock of the operator.

Japanese Patent No. 4771310 Patent No. 5216225 Japanese Patent No. 5252449 JP 2006-255690 A

  Here, it has been found that there is a need in the home for the electrostatic field generator, not the large-scale device for the greenhouse or greenhouse described above. If it is a measure against pollen, it will be used like a screen door, but it may be an effective device as a measure against mites. There are many types of ticks, but most of the ticks in the house are dust mites or leopard mites, and even dead ticks and dead bodies can cause allergies. The body length is as small as 0.2 to 0.5 mm, and it is milky white, so it can hardly be seen with the naked eye. It is said that 70 to 80% of people with allergic asthma and atopic symptoms are caused by mite house dust, and these mite allergy countermeasures are very important. Although the basic measure is to remove mites and their allergens, there is no effective measure to remove mites because they can hardly be seen with the naked eye.

  However, if the electrostatic field generator is diverted to such a household application, it cannot be applied with a high voltage like a large apparatus attached to a greenhouse or a greenhouse, and is not necessarily applied to a household window frame or the like. It cannot be grounded via the earth electrode 12 to the ground. Grounding a device for applying a high voltage to the ground requires a large-scale work such as embedding a member in the ground, and such a large-scale work is not always possible in a general household.

  Therefore, in view of the above problems, an object of the present invention is to provide an electrostatic field generator that can be driven with a small size and applied with a low voltage and that does not require grounding to ground.

  In order to achieve the above object, the electrostatic field generation device of the present invention selects two or more conductors arranged in order alternately in the order of adjacent division into two conductor groups, and one of the conductor groups A positive electrode conductor group formed by connecting a positive electrode terminal, a negative electrode conductor group formed by connecting the other conductor group to a negative electrode terminal, and a positive electrode that applies a positive potential to the positive electrode terminal using a battery. A voltage application device, a negative voltage application device that applies a negative potential to the negative electrode terminal using the battery or another battery, and a negative electrode terminal of the positive voltage application device and a negative electrode terminal of the negative voltage application device are connected. An ungrounded earth circuit having a connection line is provided, and a continuous electric field is formed between the opposing positive and negative conductors by a potential difference applied to the positive electrode conductor group and the negative electrode conductor group.

In the above configuration, the electrons pumped from the positive electrode conductor group by applying a positive voltage from the positive voltage applying device are moved to the negative voltage applying device side via the connection line of the grounding-ungrounded circuit, and the electrons are applied with the negative voltage. It is preferable that the negative electrode conductor group applied with a negative voltage of the device has a structure. Even with a ground-free grounding circuit, the necessary electron movement can be performed, and the electron movement through the ground is not required as in the prior art.
Here, as a configuration example of the positive voltage application device, it is assumed that a DC booster is provided, and the positive terminal and the negative terminal of the battery to be used are respectively connected to the positive input terminal and the negative input of the DC booster. There is one in which the output terminal of the DC booster is connected to a connection terminal to the positive conductor group, and the negative terminal of the battery is connected to the grounding-free circuit.
Here, the positive voltage application device may include a direct current booster and the battery, and the negative voltage application device may include a direct current booster and the battery or the other battery.
In addition, as the battery, either a battery, a storage / discharge type battery using electricity obtained by a solar power generation apparatus installed in the vicinity, or a storage / discharge type battery using electricity supplied from a commercial power source or Combinations thereof can be used.

With these configurations, the configuration can be simplified, and the device can be downsized, the potential can be stabilized, and a good operation can be achieved.
In the above configuration, the “positive voltage applying device” is used. However, the device is not necessarily an independent module, and may be any means that can substantially apply a positive potential to the positive terminal using a battery.
On the other hand, as a configuration example of the negative voltage application device, it is assumed that a DC booster is provided, and the battery used by the positive voltage application device or the negative electrode terminal and the positive electrode terminal of the battery used by the negative voltage application device separately from the battery. Are connected to the negative input terminal and the positive input terminal of the DC booster, the output terminal of the DC booster is connected to the connection terminal to the negative conductor group, and the negative terminal of the battery is connected to the ground-free Some are connected to a ground circuit.
Here, the positive voltage application device may include a direct current booster and the battery, and the negative voltage application device may include a direct current booster and the battery or the other battery.
In addition, the battery of the negative voltage application device is supplied from a battery, a storage / discharge type battery using electricity obtained by a solar power generation device installed in the vicinity, or a commercial power supply, similarly to the power source of the positive voltage application device. Any one of or a combination of storage and discharge type batteries using electricity can be used.
Structurally, the battery may be included in a part of the casing of the negative voltage applying device, or a battery may be provided outside the casing.
In the above configuration, the “negative voltage applying device” is used. However, the device is not necessarily an independent module, and may be any means that can substantially apply a negative potential to the negative terminal using a battery.

In the above configuration, each of the positive electrode conductor group and the negative electrode conductor group has a dielectric polarization body in which at least a part of the conductor is covered with a dielectric, and the positive electrode dielectric group and the negative electrode dielectric group It is preferable that
Here, as an example, a resistance value of about 10 @ 8 to 10 @ 11 .OMEGA. Can be used as the resistance value of the dielectric used for dielectric polarization.

  Moreover, the electrostatic field generator of this invention can also be configured such that the electrostatic catcher has a single pole configuration. The electrostatic field generator according to the present invention for a single electrode includes a single electrode conductor group formed by connecting all of two or more conductors arranged in sequence to only one of a positive electrode terminal or a negative electrode terminal, A positive voltage applying device that applies a positive potential to the positive electrode terminal when the monopolar conductor group is a positive electrode conductor group, or a negative potential at the negative electrode terminal when the monopolar conductor group is a negative electrode conductor group. Any one of the negative voltage application devices that provide the negative electrode terminal of the battery of the positive voltage application device or the negative electrode terminal of the battery of the negative voltage application device, and a neighboring conductive member different from the conductor And a grounded ungrounded circuit provided with a connection line for connecting the conductors, and a continuous electric field is formed between the opposing conductors by a potential difference generated in the unipolar conductor group and neighboring conductive members. .

Also in the above configuration, similarly to the bipolar circuit, electrons can be moved through the connection line of the grounding-ungrounded circuit, and no special grounding electrode is required.
Since it is a monopolar conductor group, when the monopolar conductor group is a negative electrode conductor group, a negative voltage application device may be used as the voltage application means. As an example of the configuration of the negative voltage applying device, a DC booster is provided, and the negative terminal and the positive terminal of the battery to be used are respectively connected to the negative input terminal and the positive input terminal of the DC booster. And connecting the output terminal of the DC type booster to the connection terminal to the negative electrode conductor group and connecting the negative terminal of the battery to the grounded ungrounded circuit.
Note that the battery may be included as part of the negative voltage application device.
When the monopolar conductor group is a positive electrode conductor group, a positive voltage applying device may be used as the voltage applying means. As an example of the configuration of the positive voltage applying device, a DC booster is provided, and the positive terminal and the negative terminal of the battery to be used are respectively connected to the positive input terminal and the negative input terminal of the DC booster. And connecting the output terminal of the DC booster to the connection terminal to the positive conductor group and connecting the negative terminal of the battery to the grounding-free circuit.
Also in the case of a monopolar conductor group, as the battery, a battery, a storage / discharge type battery using electricity obtained by a solar power generation device installed in the vicinity, or electricity supplied from a commercial power source is used. Any of the storage-discharge batteries or a combination thereof can be used.
With these configurations, a battery such as a battery can be easily configured, and the apparatus can be downsized, the potential can be stabilized, and good operation can be achieved.

  Similarly, in the above-described configuration, it is preferable that the conductors of the monopolar conductor group be a dielectric polarization body in which at least a part of the surface is covered with a dielectric to form a monopolar dielectric group.

Next, there is a conductor that becomes an electrostatic catcher, which is formed into a columnar shape or an elliptical column shape in which the cross-sectional shape of the conductor or the dielectric polarization body is circular or elliptical.
In addition, although it is the shape of the conductor used as an electrostatic catcher, there exists what was shape | molded in the flat columnar shape whose cross-sectional shape of a conductor or a dielectric polarization body is a rectangle. If it is a flat columnar shape, the shape of the formed electrostatic field tends to be uniform, and it becomes easy to supplement by providing a width of the electrostatic screen through which the flying organisms pass.
In addition, there may be a conductor or dielectric polarization body whose cross-sectional shape is formed into an airfoil column shape in which the leading edge is rounded and bulged and the trailing edge is pointed. In the case of an airfoil columnar shape, the gap is narrowed to a certain extent to ensure the capture of flying organisms by the electrostatic field generator, and further, even with a slight wind, it is easy to pass through the wing-shaped conductor or dielectric polarization body.

  Next, it is preferable to adjust the distance between the conductors arranged in order or between the dielectric polarizers arranged in order to an interval of 2 mm or more and 20 mm or less. If it is this interval, it can adjust so that a flying organism may be caught easily, maintaining air permeability.

In addition, when it is set as the window structure of the building to which the electrostatic field generator of this invention is applied, it is set as the structure which arrange | positioned the above-mentioned electrostatic field generator in the window frame, and ventilates with the external environment only through the electrostatic field generator.

A plant-growing environment, and a structure in which an electrostatic field generator is disposed on at least a part of the wall surface, ensuring ventilation with the outside world only through the electrostatic field generator, and the internal space from the outside world A shielded structure is preferable.

According to the electrostatic field generation device of the present invention, an earth-less grounding circuit can be realized, and grounding to earth, which was conventionally required, can be eliminated. As the structure of charge movement, the electrons pumped out from the positive electrode conductor group by applying a positive voltage from the positive voltage applying device are moved to the negative voltage applying device side through the connection line of the grounding ungrounded circuit, and the electrons are moved. The negative voltage applying device is configured to give to a negative electrode conductor group to which a negative voltage is applied. Similarly, when a monopolar conductor group is used, an earth-less grounding circuit can be obtained.
By adopting this groundingless grounding circuit, when installing the electrostatic field generating device and the plant protection device, grounding work with grounding, which requires the laborious work of embedding members in the ground, is unnecessary when the conventional technology is used. Therefore, it is possible to provide an electrostatic field generator and a plant protection device for households and individuals.

The positive voltage application device 120 is a power supply device for applying a positive potential to the positive electrode conductor group 110, and is connected to the positive electrode conductor group 110 via the output terminal 121.
Regarding the potential to be boosted, there is no particular limitation on the basic configuration, but here it will be described as a small-scale device for home use or the like. As an example, the voltage generated by the positive voltage applying device 120 is about 0.5 kV. Low voltage.

The output terminal 121 is a connection terminal on the output side of the positive voltage application device 120, and a high potential (for example, 0.5 kV) of the positive voltage application device 120 appears.

FIG. 2B is a diagram simply showing an example of the circuit configuration inside the positive voltage applying device 120. The inverter converts the DC voltage of the battery 124 into an AC voltage or a pulse voltage, and boosts the AC voltage or the pulse voltage with a transformer. The boosted AC voltage or pulse voltage is converted into a DC voltage by a capacitor and a diode and accumulated, and a high voltage is generated at the output terminal 121.

If it is a dry battery, it can be procured by the user of the product as a consumable and the dry battery can be inserted. Therefore, the voltage source itself is not built into the positive voltage application device 120 from the beginning, and the user himself / herself It may be exchanged.
Further, for example, a storage / discharge type battery using electricity obtained by a solar power generation device (not shown) using a solar panel installed in the vicinity of the electrostatic field generation device 100, or electricity supplied from a commercial power source. There are storage-discharge batteries that use Here, since low voltage driving is premised, it is also possible to cover with electric power stored in a storage / discharge type battery using electricity supplied from a storage / discharge type battery or a commercial power source in a solar power generation device.
1 to 7, the battery 124 is not shown as being supplied with electric energy from the outside. However, in the case of a dry battery, the electric energy contained in the battery 124 is not necessary even if there is no electric energy from the outside. In the case of a storage / discharge type battery that obtains electric energy from a solar power generation device or a storage / discharge type battery that uses electricity supplied from a commercial power supply, an input line from the outside is not shown, but the illustration is omitted. However, it is assumed that a supply line for obtaining electric energy from an external solar power generation device is secured.
In addition, the structural example which acquires electrical energy from a solar power generation device is shown in Example 3 mentioned later.
As a circuit configuration, the positive terminal of the battery 124 and the positive input terminal of the DC booster 123 are connected, and the output terminal 121 of the positive voltage applying device 120 is connected to the positive conductor group.

As will be described later, it is connected to the connection terminal 122 of the positive voltage application device 120 through the grounding / grounding circuit 150. The potential generated at the terminal 142 by the ground ungrounded circuit 150 is 0 V, which is similar to the grounded state. The operation of the earthing / grounding circuit 150 will be described later in detail.

The DC booster 143 is an electronic member that causes a voltage difference with respect to a DC component, and can be appropriately employed such as a resistor, a diode, or a transistor. It may be the same as the DC booster 123, but it is necessary to reverse the polarity.
FIG. 2A is a diagram simply showing an example of the circuit configuration inside the negative voltage applying device 140. The inverter converts the DC voltage of the battery into an AC voltage or a pulse voltage, and the AC voltage or the pulse voltage is stepped down to the negative side by a transformer. An AC voltage or a pulse voltage that has been stepped down to the negative side is converted into a DC voltage by a capacitor and a diode and accumulated, and a negative voltage is generated at the output terminal 141. The number of capacitors and diodes may be determined in consideration of the negative voltage generated at the output terminal 141.
Note that when the voltage of the battery 144 itself is a negative voltage generated at the output terminal 141, these electronic components can be omitted.
The battery 144 is a voltage source, and the type is not particularly limited. The battery 124 may be the same.
For example, there is a dry battery. Since it is premised on low voltage driving, it can be applied to dry batteries. If it is a dry battery, it can be procured by the user of the product as a consumable and the dry battery can be inserted. Therefore, the voltage source itself is not built into the negative voltage application device 140 from the beginning, and the user himself / herself It may be exchanged.
Further, for example, electricity supplied from a storage / discharge type battery or a commercial power source using electricity obtained by a photovoltaic power generation device (not shown) using a solar panel installed in the vicinity of the electrostatic field generation device 100 is used. There are storage and discharge type batteries to be used. Here, since low voltage driving is premised, it is also possible to cover with electric power stored in a storage / discharge type battery using electricity supplied from a storage / discharge type battery or a commercial power source in a solar power generation device. In addition, the application example of the solar power generation device using a solar panel is mentioned later in Example 3.

With this connection, the negative electrode terminal of the battery 144 is directly connected to the grounding / grounding circuit 150.

The grounding-ungrounded circuit 150 includes a connection line 151 that directly connects the connection terminal 122 connected to the negative terminal of the battery 124 of the positive voltage application device 120 and the connection terminal 142 connected to the negative terminal of the battery 144 of the negative voltage application device 140.

In the conventional structure in which the ground electrode is provided, the connection terminal 122 on the positive voltage application device 120 side is grounded to the ground electrode embedded in the ground, and the connection terminal 142 on the negative voltage application device 140 side is also grounded in the ground. It was structured to be grounded to the ground and to ground the earth in an independent manner.
However, if the grounding-ungrounded circuit 150 of the present invention is used, the potential of the connection terminal 122 on the positive voltage application device 120 side and the potential of the connection terminal 142 on the negative voltage application device 140 side are both maintained at approximately 0 (V). It is possible to realize the same state as each of which is grounded with respect to the ground.

3 and 4 are diagrams for briefly explaining the flow of electrons in the case of a configuration including a known ground electrode, and the flow of electrons in the case where the grounded ungrounded circuit 150 of the present invention is involved.
Originally, the function of the ground electrode is to cancel the potential of the conductive device member to 0 V so that a person who touches the conductive device member does not get an electric shock. The action of the ground electrode, such as giving an electron or pumping out electrons, can also be explained from the aspect of electron transfer for potential formation.
FIG. 3 is a diagram simply showing charge transfer for forming a potential of a device member in which a potential appears in a conventional configuration provided with a conventional ground electrode.
As shown in FIG. 3, in order for the positive electrode conductor group 110 charged to the positive electrode to form a positive potential, it is necessary to pump out electrons from the positive electrode conductor group 110 via the positive voltage application device 120 and release them to the ground. is there. It can be considered that the energy for pumping electrons from the positive electrode conductor group 110 is supplied from the positive voltage application device 120.

On the other hand, in order for the negative electrode conductor group 130 charged to the negative electrode to form a negative potential, it is necessary to apply electrons pumped from the ground to the negative electrode conductor group 130 via the negative voltage application device 140. It can be considered that the pumping energy of the electrons from the ground is supplied from the negative voltage application device 140.
Thus, in the case of the apparatus using the conventional ground electrode shown in FIG. 3, necessary electron movement is ensured by pumping or discharging electrons from the medium called the earth. At this time, a member called “earth electrode” is an indispensable member for transferring electrons to and from the ground.

  On the other hand, in the apparatus using the grounding-ungrounded circuit 150 of the present invention shown in FIG. 4, the electrons pumped out from the positive electrode conductor group 110 via the positive voltage applying device 120 are connected to the connection line 151 of the grounding-ungrounded circuit 150. It moves to the negative electrode side via the negative voltage application device 140, moves to the negative electrode conductor group 130 side, and gives to the negative electrode conductor group 130. That is, since electrons pumped from the positive electrode side are transferred to the negative electrode side without being passed through the ground, the electron movement through the ground electrode becomes unnecessary. It can be considered that the energy for pumping out and applying electrons is performed by the energy of the positive voltage applying device 120 on the positive electrode side and by the energy of the negative voltage applying device 140 on the negative electrode side. That is, a member called a ground electrode is not required, and a very compact design can be achieved, which can be said to be a structure suitable for a small-scale device such as a home for individuals.

Here, by using the grounding-ungrounded circuit 150 of the present invention, it is possible to obtain a safety function that does not cause problems such as electric shock and leakage.
3 using a conventional earth line, even if a malfunction such as abnormal contact or disconnection occurs somewhere, the charge discharge line of the positive voltage application device 120 or the charge of the negative voltage application device 140 Since any of the assembly lines can be energized, phenomena such as electric shock and leakage can occur. However, as shown in FIG. 4, in the case of a device using the grounding-ungrounded circuit 150 of the present invention, if any part of the line from the terminal 122 to the terminal 142 is disconnected, the positive voltage applying device 120 and the negative voltage applying device 140 are used. In both cases, the voltage application function is lost and the phenomenon of electric shock and electric leakage does not occur. In other words, if any failure occurs, a safety function for automatically stopping is provided. That is, the electrostatic field generation device of the present invention is a device in which safety against electric shock of an operator is sufficiently ensured without providing a ground electrode.

Next, the electrostatic field generator generated between the positive electrode conductor group 110 and the negative electrode conductor group 130 will be described.
FIG. 5 is a diagram simply showing how an electrostatic field generator is formed between the positive electrode conductor group 110 and the negative electrode conductor group 130.
As a property of static electricity, an electrostatic field is generated between a conductor charged to a positive potential and a conductor charged to a negative potential. In the configuration of FIG. 5, an electrostatic field Eab is formed between the negative electrode conductor 101a charged to a negative potential and the positive electrode conductor 101b charged to a positive potential. Similarly, an electrostatic field Ebc is formed between the positive electrode conductor 101b and the negative electrode conductor 101c, and an electrostatic field Ecd is formed between the negative electrode conductor 101c and the positive electrode conductor 101d. In this way, an electrostatic field is formed between the positive electrode conductor and the negative electrode conductor that are alternately adjacent to each other. Therefore, if the positive electrode conductor and the negative electrode conductor are alternately connected to each other, the electrostatic field is continuous. As a result, an electrostatic field generator that is like a screen as a whole is formed.

  Thus, the electrostatic field generator 100 of the present invention can form a continuous electric field between the positive and negative conductors facing each other due to the potential difference applied to the positive electrode conductor group 110 and the negative electrode conductor group 130. . In the configuration of FIG. 5, there are only four conductors 101, but a larger number of conductors 101 can be continued in the vertical direction.

  It is known that when a flying animal such as a pest, a spore or a fungus comes close to this electrostatic field generator, it is electrostatically charged. When the charged flying animal enters the electric field of the electrostatic field generator, a Coulomb force is generated and is attracted and captured by the conductor 101 charged on the opposite side. Since this principle is described in the prior patent No. 4771310 of the present inventor and the like, a detailed description thereof is omitted here.

Next, an example of an apparatus in which the electrostatic catcher is composed of a single pole will be described.
FIG. 6 is a diagram simply showing a basic configuration example of the electrostatic field generation device 100S of the present invention according to a single-pole configuration. In FIG. 6, only members necessary for understanding the present invention are shown to facilitate understanding of the internal structure, and some other members may not be shown.

The configuration example of FIG. 6 is a configuration example in which the conductor group has a single electrode structure including only the negative electrode conductor group.
The electrostatic field generating device 100S includes a negative electrode conductor group 130S, a negative voltage applying device 140, a conductive material 110S in the vicinity of a window frame or the like, and a grounding / grounding circuit 150.
Here, the unipolar conductor group is the negative electrode conductor group 130S as the negative electrode, but it is also possible to use a conductive material in the vicinity of the positive electrode conductor group and the window frame with the polarity reversed. . Since the principle is the same except that the polarity is changed, the description of the configuration having the opposite polarity is omitted.
In this configuration example, as shown in FIG. 6, the negative electrode conductor group 130 </ b> S is composed of the negative electrodes of the four conductors 101 a, 101 b, 101 c, and 101 d, but this number is an example for showing the basic configuration Only.
The conductive material 110S in the vicinity of the window frame or the like is a conductor that draws up electric charges, and may be a conductor having a certain capacitance such as a metal frame, window frame, or net. By using this conductive material 110S, it is possible to supply electrons through a ground-free circuit, and the negative voltage application device can perform a charge discharging action. In other words, the electrostatic catcher itself is a single electrode having only a negative electrode, but the entire device has a balanced charge.
The configuration in the negative voltage application device 140 may be the same as that in the case of the bipolar, and a configuration including the battery 144 and the DC booster 143 is possible, and the connection between the elements is also the same. A connection terminal 142 connected to the negative terminal of the battery 144 of the negative voltage application device 140 is connected to the grounding-free circuit 150. One end of the grounding / ungrounded circuit 150 is connected to a conductive material 110S in the vicinity of a window frame or the like so that charges can be exchanged.

FIG. 7 is a diagram for briefly explaining the operation of the grounding / grounding circuit 150 of the present invention.
Electrons pumped from the conductive material 110S in the vicinity of the window frame or the like are moved to the negative electrode side via the connection line 151 of the grounding-free circuit 150, and are transferred to the negative electrode conductor group 130S via the negative voltage application device 140. It is a structure to give. That is, the electrons pumped out from the conductive material 110S in the vicinity of the window frame or the like without passing through the ground are moved and applied to the negative electrode conductor group 130S as they are, so that the electrons are passed through the ground electrode as in the prior art. Electronic transfer is not necessary.
As described above, in the electrostatic field generation device 100 of the present invention, the electrostatic catcher constituent part can also be constituted by the positive and negative two poles of the positive electrode conductor group 110 and the negative electrode conductor group 130, and can also be constituted by the monopolar conductor group. It is also possible to do.

Next, variations in the shape of the conductor 101 will be described.
The conductor 101 is a rod-like body having a length corresponding to the width of the electrostatic field generating device to be formed, but there can be various variations.

FIG. 8 is a diagram showing variations in the cross-sectional shape of the conductor 101.
It is the longitudinal cross section taken so that the major axis of the conductor 101 might be cut | disconnected perpendicularly | vertically. In order to show the electrostatic field to be formed, only one set of the positive electrode conductor and the negative electrode conductor is lined up and down.

The pattern of FIG. 8A has a circular cross section. That is, the conductor 101 is a cylindrical body. The conductor 101 is easy to manufacture and is easy to handle because a large number of conductors 101 are easily arranged in parallel.
As can be seen from the formed electrostatic field shown on the right side of FIG. 8 (a), the electrostatic field is not uniform but a non-uniform electric field in the height direction.

The pattern in FIG. 8B has an elliptical cross section. That is, the conductor 101 is an elliptic cylinder. The conductor 101 is difficult to manufacture as compared to a cylindrical body. Arranging in parallel is relatively easy, as is the cylinder.
As shown on the right side of FIG. 8 (b), although the electrostatic field formed is not uniform as a whole, the facing area at a certain distance is widened, and the range that can be regarded as a uniform electric field is partially increased. Yes.

The pattern in FIG. 8C has a rectangular cross section. That is, the conductor 101 is a flat columnar body. The conductor 101 is difficult to manufacture as compared to a cylindrical body. Arranging in parallel is relatively easy, as is the cylinder.
As shown on the right side of FIG. 8C, the formed electrostatic field is uniform.

The pattern shown in FIG. 8D has a so-called “wing shape” in which the cross section has a rounded front edge and bulges and then has a sharp trailing edge. That is, the conductor 101 is a blade-like column. The conductor 101 is difficult to manufacture as compared to a cylindrical body. When arranging them in parallel, it is necessary to consider the direction of the airflow to be ventilated.
As shown on the right side of FIG. 8 (d), although the electrostatic field formed is not uniform as a whole, the opposing area is wide at a certain distance, and the range that can be regarded as a uniform electric field is increased. Yes.
As for the air flow, the blade-shaped one has a low fluid resistance and can be expected to improve air permeability.

  In addition, although it is the distance between the conductors 101 arranged in order, it is related to the size of the pest to be captured, the size of the spore, and the size of the fungus body. In addition, if the interval is too narrow, air permeability may be hindered, and therefore, it may be appropriately selected according to the purpose of use. As an example, the interval is adjusted to 2 mm or more and 20 mm or less. With such an interval, adjustment can be made so that airborne creatures such as fruit flies and fruit flies can be easily captured while maintaining air permeability.

Next, an example in which the electrostatic field generator 100 of the present invention described above is applied to a home screen door will be described.
FIG. 9 is a diagram simply showing an example of a home screen door 200 to which the electrostatic field generator 100 of the present invention is applied.
Usually, the positive electrode conductor group 110 and the negative electrode conductor group 130 of the present invention are formed in a window portion where a mesh-like mesh is provided, and a positive voltage application device 120 and a negative voltage application are provided in a window frame. The device 140 is charged and is configured to apply a positive potential to the positive electrode conductor group 110 and a negative potential to the negative electrode conductor group 130. Further, a grounding / grounding circuit 150 is incorporated so as to connect the positive voltage applying device 120 and the negative voltage applying device 140.
Note that the positive potential is about 0.5 kV and the negative potential is about −0.5 kV, but the flowing current is 10 μA or less, and even if the user touches, there is no electric shock.

  The basic configuration of the electrostatic field generation device 100 of the present invention and the application example to a home screen door have been briefly described above.

In the electrostatic field generator 100a according to the second embodiment of the present invention, the periphery of the conductor 101 is covered with a dielectric member to form a dielectric cover 103, the positive electrode conductor group 110 as a positive electrode dielectric group 111, and the negative electrode conductor group. 130 is the negative electrode dielectric group 131. By covering the conductor with a dielectric, electricity and electric shock due to direct contact with the user and small items placed around the user can be prevented, while charging and coulomb that are electrostatically the same as the conductor 101. Force generation is possible.
In the following description, descriptions of portions that may be the same as the configuration of the first embodiment are omitted as appropriate.

FIG. 10 is a diagram simply illustrating the configuration of the electrostatic field generation device 100a according to the second embodiment.
10 includes a positive dielectric group 110a, a positive voltage applying device 120, a negative dielectric group 130a, a negative voltage applying device 140, and a grounding / grounding circuit 150. It has a configuration.
In this configuration example, as shown in FIG. 10, the positive dielectric group 110a is composed of two dielectric covers 103, and the negative dielectric group 130a is also composed of two dielectric covers 103. It is only an example for illustration, and both the positive dielectric group 110a and the negative dielectric group 130a may be constituted by three or more dielectric coatings 103.

  As shown in FIG. 10, the dielectric cover 103 is obtained by covering the conductor 101 with a dielectric. As can be seen from the cross section, the conductor 101 is inside, and the outer periphery thereof is covered by the dielectric 102.

  The dielectric 102 is physically an insulator and is not conductive. However, it is known that when charges are applied, it polarizes inside, charges appear on the front and back surfaces, and polarizes positively and negatively. Since the intensity of this polarization is substantially equal to the charge applied from the outside, an electric field similar to the electric field appearing on the internal conductor 101 is formed on the outer periphery of the dielectric. That is, it works electrostatically like the conductor 101 shown in the first embodiment, and forms an electric field around it. Here, since the dielectric cover 103 is alternately arranged positive and negative like the conductor of the first embodiment, and is configured as a positive dielectric group 110a and a negative dielectric group 130a, the dielectric cover 103 is static as in the first embodiment. An electric field generator can be formed, and charged flying organisms can be captured.

  On the other hand, since the dielectric 102 is an insulator, there is an advantage in that there is no electrical conductivity, and electrical conduction and electric shock due to direct contact between the user and small items placed around the user are prevented.

  Since the other points of the electrostatic field generation device 100a according to the second embodiment using the dielectric coating are the same as those of the electrostatic field generation device 100 described in the first embodiment, the description here is appropriately omitted.

Example 3 is an example of the plant protection device 300 in which the electrostatic field generation device 100 shown in Example 1 or the electrostatic field generation device 100a shown in Example 2 is applied to a part of a wall surface.
Pest repellent and mold spores and fungal repellent are in great demand not only for general houses but also for plant protection equipment that grows crops such as agricultural facilities. Therefore, an example in which the electrostatic field generation device of the present invention is applied to a plant protection device will be described.

FIG. 11 is a diagram illustrating a configuration example of the plant protection apparatus 300 according to the third embodiment.
In addition, illustration and description of a support material and a fastener for tailoring the building shape are omitted.
A plant protection device 300 shown in FIG. 11 includes a wall surface 310 and a plant growing environment 320, and the electrostatic field generator 100a is provided on a part of the wall surface 310. Here, as an example, the electrostatic field generator 100a shown in the second embodiment is incorporated, but the electrostatic field generator 100 shown in the first embodiment is also applicable.

  The wall surface 310 is a wall surface that is at least partially transparent. The plant protection device 300 is shielded from the outside by the wall surface 310 and holds the internal space. Because plants need photosynthesis, the walls need to be translucent. Materials include translucent glass, plastic plates, and vinyl curtains. In order to prevent the entry of minute pests, a structure having a firm structure so that no gap is generated in all directions is preferable. Here, a plate material using a transparent acrylic resin or the like is used.

  The plant growing environment 320 is an area where the environment is arranged so that plants can be grown in the internal space blocked from the outside by the wall surface 310. Plant growth requires various conditions such as light, temperature, humidity, breathability, water, and nutritional supplementation. These conditions have been artificially adjusted. For example, plowing the ground and fertilizing the necessary fertilizer, sowing the seeds of the breeding species while controlling the temperature and humidity, and improving the environment such as watering and weed removal. This environmental maintenance often differs depending on the breeding species.

  Here, the plant protection apparatus 300 of the present invention has a structure in which the electrostatic field generator 100a is disposed on a part of the wall surface 310. The ventilation with the outside world is ensured only through the electrostatic field generator 100a, and the internal space is shielded from the outside world.

  In the configuration shown in FIG. 11, the electrostatic field generator 100a is arranged on two opposing wall surfaces, and the electrostatic field generator 100a captures flying creatures as shown in the first embodiment. Since air can be ventilated, if the electrostatic field generating device 100a is arranged on the two wall surfaces so as to face each other, it passes through the inside of the plant protection device 300 from one outside and goes out to the other outside. And good ventilation is possible.

In addition, regarding the battery 124 and the battery 144, when using a dry cell as a battery, as shown to Fig.11 (a), it can be provided in the state integrated in the electrostatic field generator 100a, but the sunlight installed in the vicinity In the case of a storage / discharge type battery that uses electricity obtained by the power generation device, a configuration as shown in FIG. 11B is possible.
FIG. 11B is a diagram illustrating a configuration example of a type using electricity obtained by the solar power generation device 160. A solar power generation device 160 with a solar panel is installed beside the house-shaped plant protection device 300, and electricity obtained by solar power generation is supplied to the battery 124 and the battery 144. The battery 124 and the battery 144 are storage / discharge type batteries. The electrostatic field generating device 100 or the electrostatic field generating device 100a is driven at a low voltage, and can be operated for 24 hours using electricity stored in the daytime.
Note that the installation of the solar power generation device 160 is not limited to the side of the plant protection device 300 as long as it is in the vicinity, and may be installed on the wall surface 310 of the house, for example.
In the case of a storage / discharge type battery that uses electricity supplied from a commercial power source, a commercial power source and a charging device may be provided near the plant protection device 300 to charge the storage / discharge type battery, or in a remote location. A charging device may be provided in an existing commercial power source to charge a storage / discharge type battery (not shown).
Since the storage / discharge type battery may be a small portable one, the charged batteries 124 and 144 may be attached to predetermined positions of the electrostatic field generator 100 or the electrostatic field generator 100a.

According to the electrostatic field generator of the present invention, it is possible to provide a simple configuration that does not require a ground electrode that is conventionally required. By adopting this grounding-ungrounded circuit, the installation of the electrostatic field generator and the plant protection device eliminates the need for ground electrode work that requires the laborious work of embedding members in the ground with the conventional technology, and the device configuration is simple. Thus, it is possible to provide an electrostatic field generation device and a plant protection device for home use and individual use.
Further, according to the plant protection apparatus of the present invention, it is possible to avoid insect pests, mold spores and fungus bodies in an agricultural facility where the outside world and the internal environment are blocked, and ventilation is sufficiently ensured. Can provide an excellent training environment.

  As mentioned above, although the Example of the electrostatic field generator of this invention, the flying animal removal apparatus, and the plant protection apparatus has been demonstrated, it is understood that various changes are possible without deviating from the technical scope of this invention. Will.
