(Embodiment)
An electrostatic adsorption partition 1 according to an embodiment of the present invention will be described below with reference to the drawings.
As shown in FIG. 1, the electrostatic attraction partition 1 includes a panel 10 and legs 50 that vertically hold and fix the panel 10 to the floor surface on which the electrostatic attraction partition 1 is arranged.

The main panel 20 has a five-layer structure, as shown in FIG. 2(A).
The center of the five layers is an insulating plate 21 as a base material, for example, a transparent plate of polyethylene terephthalate (PET) with a thickness of 1 mm.
A conductive plate 22 and a conductive plate 23 are arranged in parallel with an insulating plate 21 interposed therebetween. The conductive plates 22 and 23 are made of a conductive transparent resin which is formed by, for example, coating a polyethylenedioxythiophene (PEDOT)/polystyrene sulfonic acid (PSS) dispersion on the insulating plate 21 to a thickness of several 100 nm. is a board. The conductive plate 22 and the conductive plate 23 are insulated via the insulating plate 21 .
Further outside the conductive plates 22 and 23, a protection plate 24 is arranged to protect and insulate the conductive plates 22 and 23 from impact. The protective plate 24 is, for example, a transparent PET plate with a thickness of 100 μm.
The insulating plate 21 is an example of an insulating portion, the conductive plate 22 is an example of a positive electrode portion, and the conductive plate 23 is an example of a negative electrode portion.

As shown in FIG. 1, the leg 50 incorporates a DC booster circuit DC. The DC booster circuit DC is supplied with 5V DC power from a battery (not shown) connected to a connector CN provided on the leg portion 50 .

Specifically, the DC booster circuit DC is a circuit that boosts an input voltage supplied at 5V to an output voltage of 1000V or higher, for example, 1100V, and includes an oscillator circuit, a transformer, a capacitor, a resistor, and a diode, for example. When the switch SW is on, the positive electrode of the output of the DC booster circuit DC is electrically connected to the conductive plate 22 via the wiring W, and the negative electrode of the output of the DC booster circuit DC is electrically connected to the conductive plate 23 . is electrically connected to
A DC booster circuit DC is an example of a voltage source.

The left panel 30 and right panel 40 also have a five-layer structure similar to that of the main panel 20 . The left panel 30 and the right panel 40 are mechanically connected to the main panel 20 via hinges (not shown) so that they can be folded. Rectangular notch portions NP are formed in the lower portions of the main panel 20, the left panel 30 and the right panel 40 and adjacent to each other.
The conductive plates 22 of the main panel 20, the left panel 30 and the right panel 40 are electrically connected to each other by a flat cable FC at the notch portion NP.

(Effect of Electrostatic Adsorption Partition 1)
In the technique described in Patent Document 1, since the conductive plate 22 and the conductive plate 23 are not provided, either positively or negatively charged particles cannot be adsorbed.
On the other hand, in the electrostatic adsorption partition 1, the conductive plate 22 and the conductive plate 23 are charged either positively or negatively by the DC voltage supplied from the DC booster circuit DC. Therefore, the electrostatic adsorption partition 1 can adsorb both positively and negatively charged particles.

In addition, since the combination and arrangement of the insulating plate 21 and the conductive plates 22 and 23 exhibit the function of a capacitor, the electrostatic adsorption partition 1 makes it difficult for charges to escape, and can stably adsorb charged particles. .

As described above, the electrostatic adsorption partition 1 is supplied with 5V DC power from the battery. Since the conductive plates 22 and 23 are insulated by the insulating plate 21, it is difficult for current to flow between the conductive plates 22 and 23. FIG.
Therefore, the power consumption of the electrostatic adsorption partition 1 is relatively small.

Since the insulating plate 21, the conductive plates 22 and 23, and the protective plate 24 are all transparent, the electrostatic attraction partition 1 does not block the view.

Since the left panel 30 and the right panel 40 can be folded toward the main panel 20, the electrostatic attraction partition 1 can be stored compactly.

Since the conductive plates 22 and 23 are protected by the protective plate 24, it is easy to clean the particles that have been adsorbed, and even if the hands, feet, face, etc. come into contact with the electrostatic adsorption partition 1, it is difficult to feel uncomfortable due to the voltage.

The electrostatic attraction partition 1 does not have moving parts such as motors and fans. Therefore, the electrostatic attraction partition 1 is silent even during operation.

The shape, material, thickness, etc. of the insulating plate 21, the conductive plates 22 and 23, and the protective plate 24 are not limited to those described above. Materials for the insulating plate 21 and the protective plate 24 may be, for example, acrylic resin, polycarbonate, glass, paper, and cloth. The material of the conductive plates 22 and 23 may be, for example, indium oxide or zinc oxide. The insulating plate 21, conductive plates 22 and 23, and protective plate 24 may be colored or colorless, and may not be transparent. The insulating plate 21, the conductive plates 22 and 23, and the protective plate 24 may be curved, may not have a constant thickness, and may be formed in a shape other than a flat plate, such as a corrugated shape or a spherical shape. It may have been Regarding the insulating plate 21, the conductive plates 22, 23 and the protective plate 24, the "plate" may be a film, layer, or the like.

The protection plate 24 may be formed by coating the surfaces of the conductive plates 22 and 23 with a paint having higher insulating properties than the conductive plates 22 and 23 . For example, a protective plate 24 coated with urethane resin-based paint in a thickness of 30 μm to 40 μm may be used. In addition, enamel-based, lacquer-based, acrylic, epoxy-based, fluorine-based, and silicone-based paints may be used as the paint. Furthermore, these paints may be colored or colorless.

Also, the configuration of the DC booster circuit DC and the input and output voltages are not limited to those described above.

The arrangement of the main panel 20, the left panel 30 and the right panel 40 is not limited to that described above. The electrostatic adsorption partition 1 may lack the left panel 30 or the right panel 40 or may include panels other than the main panel 20 , the left panel 30 and the right panel 40 .
The left panel 30 and right panel 40 may have different constructions than the main panel 20 . The left panel 30 and right panel 40 may be electrically connected to or insulated from the main panel 20 .

(Modification)
The panel 60 of the electrostatic attraction partition 2 according to the modification has a structure different from that of the panel 10 of the electrostatic attraction partition 1 . The following description will focus on portions that differ from the panel 10. FIG.

As shown in FIGS. 3A and 3B, the panel 60 has a plurality of holes H. As shown in FIGS. These holes H pass through the panel 60 .

As indicated by plus or minus signs and arrows in FIG. It is attracted to the surface of the protective plate 24 in contact with the conductive plate 23 or the conductive plate 22 on the other side.

Therefore, regardless of whether the fine particles floating in the air are positively charged or negatively charged, the fine particles are attracted to the panel 60 on either side of the conductive plate 22 or the conductive plate 23. .
Therefore, the electrostatic adsorption partition 2 can efficiently adsorb charged fine particles compared to the electrostatic adsorption partition 1 .

The panels 10 and 60 described above can be applied not only to the electrostatic adsorption partitions 1 and 2, but also to windows, doors, walls and the like.
