Description

DUST-REPELLENT NET WITH TRIBOELECTRIC DUST COLLECTION AND REMOVAL FUNCTION

The present invention relates to a dust-proof mesh technology that collects (collects) and removes dust in the air flowing into a room by a triboelectric charging method. It is possible, and it is possible to automatically remove the dust collected, it relates to a technology for increasing the efficiency of triboelectric charging and easily collecting dust for cleaning during dust collection.

In general, a window should be opened for indoor ventilation, and an insect screen or a filter type dust screen is installed on the window frame to prevent the inflow of insects, harmful substances, etc. when the window is opened. In these insect screens and dustproof nets, particles are filtered according to the size of the through holes, and accordingly, the particles are adsorbed to the insect screens and dustproof nets, and periodic cleaning is required.

In addition, for example, since the insect screen only performs the function of the insect screen, the problem that fine dust cannot be filtered at all has been pointed out. Accordingly, in Korean Patent Registration No. 10-1946357, etc., when the insect screen is configured in two layers, the insect screen is spaced apart between the two layers, and the two layers of the insect screen are rubbed against each other by an external force such as wind, by frictional charging Techniques to remove fine dust are posted.

In triboelectric charging, when a material composed of a triboelectric material is rubbed against each other, it has a property of being charged to a cathode and an anode, respectively. It is configured to be collected.

However, in this existing technology, even if frictional charging is made due to external force, it is impossible to immediately separate the meshes on both sides that are in contact by friction. Since the large electric power is reduced, there is a problem that the dust collecting effect is extremely insignificant.

In addition, in the end, particles may be in a state of being adsorbed to the net, and in particular, when dust is adsorbed between the two nets, it is very difficult to clean it, and thus the lifespan of the dust net is reduced.

In addition, since dust is inevitably adsorbed to the entire area of the net, it is inconvenient to wash it, and thus, the usability thereof is greatly reduced.

Accordingly, in the present invention, in a technology for collecting and removing dust in the air flowing into a room in a triboelectric charging method, the frictional electric force can be effectively maintained in the nets on both sides, while the removal of the dust collected is partially automatic. One purpose is to provide a technology that can improve the holding power until the time when cleaning is required.

Another object of the present invention is to provide a technique for increasing usability according to the ease of cleaning by limiting the area where the dust is adsorbed for easy cleaning.

In order to achieve the above object, according to an embodiment of the present invention, the dust protection net including the dust collection and removal function of the triboelectric charging method is composed of a triboelectric charging material, and a plurality of first through holes are formed to allow air to pass through. a first network to be; a second mesh spaced apart from the first mesh, made of a triboelectric material, and having a plurality of second apertures different from the first aperture at least one of a location, a pattern, a shape, and a size to allow air to pass therethrough; Mesh friction that is formed on a portion of the first and second meshes, and friction electricity is generated in the first and second meshes when the first and second meshes are rubbed against each other by an external force wealth; and a connection part that insulates and connects the first and second meshes to each other in addition to the mesh friction part, wherein friction electricity is generated in the first mesh and the second mesh by friction between the mesh friction parts. , when any one of a cathode and an anode is formed in each of the first and second networks according to charging characteristics in the regions of the first and second networks that are insulated and connected by the connection part, the first network and It is characterized in that the dust in the air passing through the second mesh is charged by the negatively charged meshes among the first and second meshes, and the dust is collected in the positively charged meshes.

Preferably, when the first mesh faces the outside and the second mesh faces the room, the first mesh is negatively charged and the second mesh is positively charged.

The mesh friction part is formed on at least one of the first mesh and the second mesh, and when the external force is removed after the first mesh and the second mesh come into frictional contact with each other by an external force, the first mesh and a mesh elastic part for allowing the second mesh to be spaced apart from each other. Including, triboelectric electricity generated as the first and second meshes are in frictional contact with each other is applied to the first and second networks, respectively. Then, it is preferable to insulate them from each other to prevent a short circuit of the triboelectric applied to the first mesh and the second mesh.

The elastic mesh portion is formed on at least one of the first network and the second network, and is preferably an elastic body having an elastic restoring force that moves the first network and the second network apart.

The mesh friction part is preferably configured to have a fine concavo-convex structure.

In the positively charged nets among the first and second nets, at least when the movement direction of air is set in the horizontal direction, the area in the direction opposite to the direction in which the air flows among the horizontal areas is the triboelectric charging material. It is preferable that the exposed area except for the area where the triboelectric charging material is exposed is configured to be insulated, so that the dust is concentrated and collected in the area in the interior direction where the triboelectric charging material is exposed.

The first net and the second net are characterized in that they have a mesh structure in which a yarn of a triboelectric charging material has a gap between the first and second through holes, and the first and second nets have a mesh structure. Among the nets, the positively charged nets are preferably woven to have different yarn densities for each area, so that dust is relatively concentrated and collected in areas with high yarn density.

Preferably, the region having a high yarn density is formed to protrude in a direction opposite to a direction in which the first and second nets face each other.

It is preferable to further include a; dust-proof filter net which is installed on the side closest to the indoor side of the first net and the second net and made of nanofibers.

It is preferable that an edge end of the first mesh and the second mesh contact the window frame is made of an insulator.

According to the present invention, the regions except for the mesh friction part where triboelectric charging is performed are connected through the connection part of the insulator, so that when the mesh friction part is separated after friction, the first mesh is charged with different poles of the negative electrode or the positive electrode, respectively; The short circuit of the second network is prevented, so that the high power can be maintained for a long time, and thus the charging and dust collecting effects are maximized.

In particular, according to the fine concavo-convex structure of the elastic part and the mesh friction part region, the effect of increasing the frictional charging effect and the increase of the frictional charging force due to the separation and re-contact of the first and second nets after charging and the improvement of the holding force thereof have.

On the other hand, according to the above-described elastic part, when separated after being charged by the mesh friction part, the first and second meshes are shaken by the elastic force and are separated and contact again, so that part of the dust in the previously collected state is repeated. Since it is separated from the mesh and falls to the bottom, there is an effect that the holding force until the cleaning time is greatly increased.

In addition, through the differentiation of the insulating coating structure and yarn density of the positively charged net, the dust is collected only in some areas, preferably in some areas facing the room, and the phenomenon that dust is collected between the first and second nets is prevented. It can be minimized, and the convenience of washing is increased, and there is an effect of increasing the esthetics.

It is a partial perspective view for explaining the structure of the dust protection net with the removal function. In the following description, a plurality of drawings will be simultaneously referenced and described in order to describe one technical feature or component constituting the invention.

Referring to the above-described drawings together, the dust protection net including the dust collection and removal function of the triboelectric charging method according to an embodiment of the present invention includes a first net 10, a second net 20, and a net friction part. (30) and characterized in that it includes a connection portion (40).

The first network 10 and the second network 20 are characterized in that they have almost similar structures. In the following description of the present invention, it is exemplified that the first net 10 is installed outdoors and the second net 20 faces the indoor side, which is particularly dependent on the yarn structure and density of the second net 20 . In various embodiments of the present invention to be described later, the installation direction functions to exhibit a characteristic effect. However, in other embodiments, it may be understood that the installation positions of the first network 10 and the second network 20 may be interchanged with each other.

The first mesh 10 is made of a triboelectric material, and a plurality of first through holes are formed to allow air to pass therethrough, and the second mesh 20 is spaced apart from the first mesh, and a triboelectric material is formed. Consists of, as shown in FIG. 1 , a plurality of second through holes having at least one different from the first through hole in position, pattern, shape, and size are formed to mean a configuration configured to allow air to pass therethrough.

The formation of the first through hole and the second through hole differently prevents the air from passing in a straight line, increases the time for air to pass through the first mesh 10 and the second mesh 20, and further increases the efficiency of discharge and dust collection. increase effect is obtained.

In the present invention, the first net 10 and the second net 20 are made of a triboelectric material. The triboelectrically charged material is a material that is charged with a positive electrode or a negative electrode when rubbed against each other, and includes, for example, ceramic nanocomposite materials, polyurethane foam, and the like. In addition, in the present invention, the above-described frictional charging material can be applied only to the regions of the first and second meshes 10 and 20 corresponding to the mesh friction part 30 to be described later, and the other first meshes 10 . and the second mesh 20 may be composed of a conductor through which charged triboelectric electricity can flow.

In the present invention, the first and second through-holes refer to a through structure through which air can flow in the first and second meshes 10 and 20, as shown in FIG. 1 and the like. For example, like the general insect screen shown in FIG. 1 , the first mesh 10 and the second mesh 20 are the above-mentioned triboelectric material or yarn of the conductor to adjust the gap between the first through hole and the second through hole. In the case of a mesh structure woven to have a woven structure, a through structure between the yarns of the woven structure may mean a first through hole and a second through hole. Of course, in the present invention, the size of the first through hole and the second through hole is preferably set to be smaller than the size of the through hole of the insect screen.

As described above, the mesh friction part 30 is formed on a part of the first mesh 10 and the second mesh 20 as shown in FIG. The second mesh 20 rubs against each other, meaning an area in which triboelectric electricity is generated in the first mesh 10 and the second mesh 20 .

At this time, even with a small external force, the first net 10 and the second net 20 should rub against each other, and according to the fixing structure of the first net 10 and the second net 20, it is fixed to the window frame (not shown). Since contact between the first mesh 10 and the second mesh 20 is impossible in the area, preferably, the mesh friction part 30 is the center area of each mesh 10 and 20, as shown in FIG. 1 and the like. It is preferable to refer to spring.

As described above, in another embodiment of the present invention, the mesh friction part 30 may be made of a triboelectric charging material, and regions of the meshes 10 and 20 excluding the mesh friction part 30 may be made of a conductor. . In addition, since the first mesh 10 and the second mesh 20 need to be contacted and rubbed against each other even with a small external force, their elasticity and elasticity can be set to be maximum in the area of the mesh friction part 30 . In this case, elasticity and elasticity may be implemented according to the characteristics of the material itself, or, for example, in the case of a yarn weaving type net as described above, may be implemented by adjusting the weaving density thereof.

The connection part 40 has a configuration like a 'insulator' that connects the first network 10 and the second network 20 so as to be insulated from each other in an area other than the area where the mesh finish part 30 is formed, but the size may mean a very small, preferably cylindrical or disk-shaped element configured to correspond to the interval between the first and second networks 10 and 20 as shown in FIG. 2 .

According to this configuration, as shown in (a) of FIG. 3 , when an external force is applied to the first mesh 10 while the air moves, the first mesh 10 and the second mesh 20 come into contact with each other. As shown in FIG. 3(b) by the friction between the mesh friction parts 30, friction electricity is generated as the first mesh 10 and the second mesh 20 are positively or negatively charged to each other, and the connection part In the regions of the first and second nets 10 and 20 that are insulated by ( 40 ), one of a cathode and an anode is formed in each of the first and second nets 10 and 20 according to charging characteristics. do.

In this case, in the process of air moving while passing through the first and second meshes 10 and 20, dust such as fine dust and dust in the air is negatively charged while passing through the negatively charged mesh, and the anode It is implemented so that the charged dust is collected while passing through the electrically charged net and collected on the positively charged net.

Due to this phenomenon, it is possible to implement a dustproof net that can be recycled through washing and drying with very high efficiency by replacing a general dustproof net that is expensive and needs to be replaced frequently.

In particular, according to the configuration of the mesh friction part 30 and the connection part 40 described above, it is possible to collect dust using natural wind in a mechanism almost similar to an actual electric dust collector, so that it is possible to manufacture a very effective and practical dustproof net. It works.

On the other hand, in the process of air movement as described above, it is preferable that dust is first charged to the cathode by electrons by the negatively charged net, and then collected in the net by the positively charged net on the subsequent movement path. do. Considering this dust collection mechanism and the flow of air in a general window, in one embodiment of the present invention, the case in which the first mesh 10 faces the outside and the second mesh 20 is disposed toward the interior is generally It is desirable to consider

In this case, using the characteristics of the triboelectric material, etc., in the present invention, the structure is the same as or different from each other as described above, but in the material, as shown in FIG. 3 (b), the first net 10 is As a negative electrode, the material of the second network 20 may be configured to be positively charged. As described above, it may be understood that these material properties are also limited to the area where the mesh friction part 30 is formed.

On the other hand, when each of the first net 10 or the second net 20 is positively or negatively charged by friction charging, the first net 10 and the second net 20 are 20) continues, the large power may disappear while the electrons moved by the charging re-migrate, or additional friction does not occur, so that the charging effect is lowered, and the dust collecting effect may also be lowered accordingly.

In order to prevent this phenomenon, mesh elastic parts 11 and 21 may be installed or formed in the mesh friction part 30 of the present invention as shown in FIG. 4 . Although the mesh elastic parts 11 and 21 are represented as coil springs in FIG. 4 for better understanding, it may be implemented as a leaf spring, a structure such as a plate spring of the mesh structure itself.

That is, the mesh elastic parts 11 and 21 are formed on at least one of the first mesh 10 and the second mesh 20, and as shown in FIG. 4 (a), the first mesh ( 20) and the second mesh 20 are in frictional contact with each other, and when the external force is removed, the function so that the first mesh 10 and the second mesh 20 are spaced apart from each other as shown in FIG. do.

According to this, triboelectric electricity generated as the first mesh 10 and the second mesh 20 are in frictional contact with each other is applied to the first mesh 10 and the second mesh 20, respectively, and then insulated from each other. There is an effect of preventing a short circuit of the triboelectric applied to the first mesh 10 and the second mesh 20 . In addition, since the first mesh 10 and the second mesh 20 are separated every time they are in contact by the elastic mesh parts 11 and 21, contact and separation are repeated very frequently by an external force, the friction amount rapidly increases, There is an effect that can be maximized.

In addition, according to the elastic parts 11 and 21, when separated after being charged by the mesh friction part 20, the first mesh 10 and the second mesh 20 are separated and contacted again while shaking by the elastic force. Because part of the dust in the previously collected state is separated from the net and falls to the lower part due to repetition, the amount of dust adsorbed to the net can be relatively reduced, and users only need to wipe the dust that has fallen on the lower part, Due to the mesh adsorption, air does not pass through, or the aesthetics are adversely affected, which has the effect of significantly increasing the holding power until the time of washing, which eventually requires washing.

For the implementation of this embodiment, the mesh elastic parts 11 and 21 are formed in at least one of the first network 10 and the second network 20, as described above, and the first network 10 and It may be preferable that the second mesh 20 is an elastic body having an elastic restoring force to move away from each other.

In addition, in order to assist the function of the connection part 40 and prevent a short circuit during charging, it is preferable that the first net 10 and the second net 20 are made of an insulator at the end of the edge contacting the window frame.

On the other hand, it is preferable that the structure of the mesh friction part 30, which is an area where the first mesh 10 and the second mesh 20 are in contact, is configured to maximize the friction effect. The large force due to friction is also related to the friction contact area and friction roughness. In order to implement this, in another embodiment of the present invention, as shown in FIG. 5 , the mesh friction part 30 is preferably configured to have a fine concavo-convex structure 31 .

On the other hand, in the present invention, dust is collected on the net by using the electrostatic precipitation phenomenon. Dust may be collected between (20). In this case, it is advantageous for cleaning that the first network 10 and the second network 20 are configured to be separable from each other, but in this case, there is a problem in that the manufacturing cost is greatly increased. Alternatively, if the first net 10 and the second net 20 are not configured to be separable from each other, there may be a problem in cleaning efficiency.

Accordingly, in another embodiment of the present invention, it is important not to collect dust between the first net 10 and the second net 20 as much as possible. To this end, as shown in FIG. 6 , a positively charged network among the first network 10 and the second network 20 , that is, in the above-described embodiment, the second network 20 is disposed toward the indoor (In) side. At least, when the movement direction of air is set in the horizontal direction, the triboelectric charging material 21 is exposed and the triboelectric charging material 21 is exposed in the region opposite to the air inflow direction among the horizontal regions. It is preferable that the region except for the insulating coating 22 is configured so that the dust is concentrated in the area in the interior direction where the triboelectric charging material 21 is exposed. In the above-described example, it will be natural that the material may be replaced with a conductor instead of the triboelectric material 21 depending on the area thereof. In addition, the insulating coating 22 is preferably made of a degreasing material so that dust or the like is not adsorbed, so that even if dust adheres to the insulating coating 22, the nearby triboelectric charging material 21 is immediately moved to the exposed portion. can do.

In this case, the phenomenon of dust being collected between the first net 10 and the second net 20 is prevented by preventing dust from being collected in the area between the first net 10 and the second net 20 as much as possible. Since it can be minimized, the need to separate the first net 10 and the second net 20 from each other is minimized, so that the convenience of cleaning and the reduction of the manufacturing cost are secured, and the aesthetics is also increased.

On the other hand, it is easier to clean the dust when the dust is concentrated at one point than when the dust is collected thinly over the entire net (10, 20). That is, when dust is agglomerated, it is more convenient to remove the dust than when the dust is spread thinly.

In order to apply this principle to the present invention, in the present invention, as shown in (a) of FIG. In the case of a mesh structure woven to have, positively charged nets among the first net 10 and the second net 20, that is, in the above example, the second net 20 is a different yarn for each area. It is preferable to be woven to have a density, so that the dust is relatively concentrated in the area P having a high yarn density. In this case, dust can be collected almost like a lump for each P area, so that cleaning becomes very easy as described above.

On the other hand, when the dust is collected like a lump, in order to separate a lump of dust from the nets 10 and 20, it is preferable that the dust is collected to protrude so as to facilitate removal of the lump. For this purpose, as shown in (b) of FIG. 7 , it is preferable that the area having a high yarn density protrude in a direction opposite to the direction in which the first net 10 and the second net 20 are facing each other. According to this, the removal effect at the time of removing the dust lump can be increased by preventing the phenomenon that the dust is collected as if it is buried toward the net.

On the other hand, in the structure of the electrostatic dust collection type described above, when the wind does not blow, the effect is extremely reduced. In this case, in order to block the inflow of fine dust, etc., the first net 10 and the second net 20 are included in the dust-proof net including the dust collection and removal function of the triboelectric charging method according to another embodiment of the present invention. A dust-proof filter network 50 that is installed on the closest side to the indoor side of the and is made of nanofibers like a general dust-proof net may be further included.

As described above, although the embodiments have been described with reference to the limited embodiments and drawings, those skilled in the art will understand that various modifications and variations are possible from the above description. Terms such as "include", "comprise" or "have" described above mean that a component without a particularly opposing description may be embedded, so other components are not excluded. It should be construed as being able to include more. In addition, the protection scope of the present invention should be construed by the following claims, and all technical ideas within the scope equivalent thereto should be construed as being included in the scope of the present invention.
