Description

[0001] Apparatus and method for preventing dust deposition [

The present invention relates to an apparatus and method for preventing dust deposition, and more particularly, to a dust deposit prevention apparatus and method capable of guiding dust accumulated on a surface to the outside of a dust elimination dead zone by using a dielectric dynamic force.

Conventional dust shielding or removing devices use the principle of adsorbing or collecting indoor air pollutants to be removed and separated in an intermediate medium such as a filter. The dust removal by the negative ion generator is characterized in that it removes a large amount of negative ions into the air to reduce harmful substances and odors in the air, but there is a disadvantage that it generates harmful stimuli to human body breathing by generating ozone simultaneously in the air cleaning process. Particularly, an electric dust collector which removes dust by an electric principle generates a corona discharge in a cathode which is a cathode, charges particles in an anode collector, collects dust, and then removes dust using a chattering device. In this case, since a DC high voltage of 12 kV is required, the electric dust collector is mainly used as an air cleaning device in a large-sized industrial field, which is not suitable for controlling small amount of fine dust and dust can be removed from the dust collecting plate.

Generally, the pollution source of fine dust accumulated in the room of the multi-use facility can be classified as a part caused by various activities such as soot, dust and the like that are introduced from the outside and cooking, smoking, and cleaning indoor, Is most likely to occur during the most active time and eventually the fine dust enters the respiration of the inhabitants and most of the dust accumulates on the surface of the interior structure.

When the dust accumulates on the surface of the structure, the dust accumulates in various places and it accumulates continuously in four zones that are difficult to physically remove. After a certain period of time, it is re-injured by natural ventilation or external stimulation by the air- And can be fatal to people living in the room again with high concentration of fine dust.

Therefore, it is difficult to control fine dust that is accumulated in an area or indoor structure which is difficult to artificially or physically removed from a multi-use facility. However, since the concentration of fine dust increases over time, Which can adversely affect the health of a person in a high concentration. In addition, when complicated facilities such as a room of a multi-use facility are located, it is difficult to physically remove areas where micro dust is difficult to remove and various methods must be mobilized for artificial cleaning and removal. have.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a dust deposit prevention apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a dust deposit prevention apparatus according to an embodiment of the present invention, and FIG. 2 is a conceptual view of a principle in which dust is guided according to an embodiment of the present invention.

1, a dust deposit prevention apparatus 10 according to an embodiment of the present invention includes a three-phase alternator 100 and a three-phase alternator 100 connected to the three- And an electrode substrate 200 provided on the surface.

In describing the dust deposit prevention device 10 of the present invention, the dust removal blind spot 20 is installed in a space or a wall where dust can not easily be removed due to the corner portion inside the building or various furniture and appliances. Which means the upper part of various furniture and appliances. However, the dust removing blind spot 20 is not limited to this.

The three-phase alternating current generator 100 is connected in parallel to the electrode substrate 200 to supply a small amount of voltage to the dust 30 dropped on the surface of the electrode substrate 200 in three phases.

The reason why the three-phase alternating-current generator 100 and the electrode substrate 200 are connected in parallel is that the three-phase alternating-current voltage generated by the three-phase alternating-current generator 100 is uniformly supplied to the electrode substrate 200 It is for this reason.

The electrode substrate 200 forms a non-uniform electric field by using a three-phase AC voltage generated from the three-phase alternating-current generator 100 to form a dielectrophoretic force.

Dielectric power refers to the force exerted when a particle containing a polarizing material or having an internal dipole moment is placed on a non-uniform electric field.

Generally, a standing wave is generated in a single-phase alternator (not shown), whereas a traversing wave in which three phases are different from each other is generated in the three-phase alternating current generator 100 as shown in FIG. Due to this, the particles having the dipole moment can move by the phase difference of the different traveling waves.

Therefore, the dust 30 dropped on the surface of the electrode substrate 200 can be lifted from the surface of the electrode substrate 200 by the dielectrophoretic force described above, and can be guided to the outside of the dust-removing blind spot 20.

The dust 30 introduced outside the dust removal blind spot 20 can be removed by the dust collector 300 shown in FIG.

Accordingly, the dust 30 falling on the dust removing blind spot 20, which is not exposed to human hands or does not come in contact with various devices for dust removal, is guided and removed to a specific area, 30 can be prevented from accumulating and can be easily removed.

Although the dust collector 300 is used to remove the dust 30 introduced into the dust removal blind spot 20 in the present embodiment, the dust removal blind spot 20 may be removed from the dust removal blind spot 20 by various devices or methods. The induced dust 30 can be removed, and dust collection can be made more effective by using a blower (not shown).

Meanwhile, the three-phase alternating current generator 100 may be provided with a timer 120 as shown in FIG.

The timer 120 may periodically generate a three-phase alternating voltage generated from the three-phase alternating current generator 100. As a result, the electrode substrate 200 that forms a uniform electric field by using the three-phase AC voltage also periodically generates a uniform electric field, resulting in a periodic dielectric power.

Accordingly, the dust 30 falling on the surface of the electrode substrate 200 can be guided to the outside of the dust-removing blind spot 20 periodically by a dielectrophoretic force.

Also, even when the three-phase AC voltage is continuously supplied to the electrode substrate 200 without supplying the AC voltage to the electrode substrate 200, the dust 30 can be guided to the outside of the dust-removing blind spot 20.

Therefore, the amount of electric power supplied to the three-phase alternating-current generator 100 can be reduced more than when the three-phase alternating-current voltage is continuously supplied to the electrode substrate 200.

In addition, it is possible to prevent the dust 30, which has already been collected, from flying again when the dust 30 introduced to the outside of the dust removing blind spot 20 is periodically removed.

In addition, since the three-phase alternator 100 is operated in accordance with the frequent occurrence of the dust 30, the dust 30 is prevented from accumulating, thereby reducing unnecessary power consumption and preventing accumulation of the dust 30 Can be exercised.

The three-phase alternating current generator 100 and the electrode substrate 200 are connected to each other by a tie line 110. As described above, the three-phase alternating-current generator 100 may be connected to the electrode substrate 200 in parallel by a tie wire 110.

The three-phase alternating-current generator 100 is preferably positioned close to the electrode substrate 200. If the three-phase alternator 100 is not positioned close to the electrode substrate 200, the length of the wire 110 may become long, which may damage the appearance of the inside of the building. When the three-phase alternator 100 can not be positioned close to the electrode substrate 200, it is necessary to use the molding so as to bury the tie wire 110 on the wall or floor or to prevent the tie wire 110 from being exposed to the maximum extent. .

Also, the three-phase alternator 100 may be connected to a switch (not shown). The switch is provided at a position easily accessible by a human hand, so that the user can easily operate the three-phase alternator 100.

Meanwhile, the above-mentioned dust removal blind spot 20 may be formed in a flat and angular space, but it may be formed in a polygonal space or a curved space according to circumstances.

When the electrode substrate 200 is installed without considering the shape of the polygonal dust-removing blind spot 20 as described above, another blind spot where the electrode substrate 200 is not installed may occur.

If the curved shape is not taken into account, a gap is formed between the curved portion and the electrode substrate 200, so that the dust 30 can fall and accumulate between the gaps.

As a result, the dust deposit preventing apparatus 10 can not exhibit the original effect properly. Therefore, the electrode substrate 200 should be installed so as to fit the dust removing blind spot 20.

Hereinafter, the electrode substrate 200 will be described in more detail.

FIG. 3 is a front view of an electrode substrate according to an embodiment of the present invention, and FIG. 4 is a sectional view of a portion A of FIG.

3 to 4, the electrode substrate 200 according to an embodiment of the present invention includes a PCB substrate 210 and an electrode 220 disposed on the PCB substrate 210.

The electrode substrate 200 may be formed in a thin film shape and cut according to the surface shape or area of the dust removing blind spot 20.

Therefore, since the electrode substrate 200 can be provided by cutting the polygonal shape of the dust-removing blind spot 20, it is possible to prevent another blind spot where the electrode substrate 200 is not installed. In addition, since it is easy to bend or cut in accordance with the curved shape, a gap is formed between the curved portion and the electrode substrate 200, and the dust 30 can be prevented from falling and accumulating between the gaps.

On the other hand, the PCB substrate 210 can be made of a flexible material such as plastic instead of a glass substrate, which is not easy to bend because it has no conventional flexibility.

The electrodes 220 provided on the PCB substrate 210 are made of copper and patterned to have a thickness of 1 mm and an interval of 200 μm.

Therefore, the electrode substrate 200 can be easily cut or bent according to the mounting surface.

Here, the shape of the electrode 220 to be patterned may be formed in the form of a polygonal shape, but it is most preferable to form the electrode 220 in the form of a circle or a circle in terms of productivity and economy.

In addition, in order to prevent a safety accident that may occur when a part of a human body touches the electrode substrate 200 on the surface of the electrode substrate 200 and to prevent another electrical substance from touching the electrode substrate 200, The insulating coating 230 is processed.

As the material used for the insulating coating 230, epoxy, urethane, polyester, acrylic, or the like may be used.

On the other hand, an attaching patch 240 is provided below the electrode substrate 200.

The attachment patch 240 is attached to the electrode substrate 200 attached to the dust removal blind spot 20 so that the electrode substrate 200 cut or bent according to the shape of the dust removal blind spot 20 can be easily attached, The adhesion force can be improved.

The attachment patch 240 is also made of a material that is easy to cut and bend, and can be easily cut or bent when the electrode substrate 200 is cut or bent.

Next, another embodiment of the electrode substrate 200 of the present invention will be described in detail. In the following description, only different parts from the above-described embodiment will be described in detail and the same or similar parts will not be described in detail.

5 is a cross-sectional view of an electrode substrate according to another embodiment of the present invention.

4 to 5, another electrode substrate 200 according to another embodiment of the present invention includes a PCB substrate 210 and an electrode 220 disposed on the PCB substrate 210.

The surface of the electrode substrate 200 is formed as an inclined surface 250. The central portion of the electrode substrate 200 is formed higher than both ends of the electrode substrate 200 so that dust 30 falling on the surface of the electrode substrate 200 will be naturally removed from the dust removing blind spot 20, ) To the outside.

Accordingly, the dust 30 dropped on the surface of the dust-removing blind spot 20 can be guided to the outside of the dust-removing blind spot 20 without forming the dielectric smoothing force.

The electrode substrate 200 is moved to a specific position on the dust removing blind spot 20 by the inclined surface 250 of the electrode substrate 200 without being guided to the outside of the dust removing blind spot 20, . At this time, the dust 30 moved to a specific position may be guided to the outside of the dust removing blind spot 20 by forming a dielectric power.

Therefore, since the induction distance for guiding the dust 30 to the outside of the dust removing blind spot 20 is shortened, the amount of the dielectrophoretic force can be reduced. Accordingly, the amount of power of the three-phase alternating-current generator 100 supplied to form the dielectrophoretic force is also reduced, which is effective in terms of economy.

The inclined surface 250 of the electrode substrate 200 having the inclined surface 250 is treated with a titanium dioxide (TiO 2) coating 260.

The titanium dioxide coating 260 is designed to be easily moved by gravity after the dust 30 drops onto the electrode substrate 200.

In addition, since the electrode substrate 200 has an insulating property, the insulating coating 230 may be omitted and the titanium dioxide coating 260 may be processed. The electrode substrate 200 may be treated with the titanium dioxide coating 260 after the insulating coating 230. In this embodiment, the insulating coating 230 is omitted.

Although it is not shown in the drawing, the step of installing the dust collector 300 before the step of removing the dust 30 introduced to the outside of the dust removing blind spot 20 by the flow transferring force .

Before the step S110 of installing the electrode substrate 200 on the surface of the dust removing blind spot 20, the area and shape of the dust removing blind spot 20 to be installed on the electrode substrate 200 are grasped And at least one electrode substrate 200 may be connected in parallel with the three-phase alternating current generator 100 by cutting the electrode substrate 200 in accordance with the dust removing blind spot 20.

It is preferable to clean the dust removing blind spot 20 so that there is no dust 30 on the surface of the dust removing blind spot 20 before the step of setting the electrode substrate 200 on the surface of the dust removing blind spot 20 . This is to further improve the adhesion of the patch 240 provided under the electrode substrate 200.

As described above, the dust deposit prevention apparatus 10 of the present invention includes the three-phase alternating-current generator 100 and the electrode substrate 200 to form a dielectrophoretic force, thereby dropping into the dust removing blind spot 20 The dust 30 can be guided to the outside of the dust-removing blind spot 20, so that the dust-settling of the dust-removing blind spot 20 can be prevented.

Since the dust 30 is guided to the outside of the dust removing blind spot 20, the dust 30 can be removed more easily and it is necessary to remove the dust 30 accumulated in the dust removing blind spot 20 Cost savings.
