BEST MODE

[0064] Hereinafter, an electrical dust collection device 100 including a charging part 1000 and a dust collection part 2000 according to the present invention having the configuration as described above will be described in detail with reference to the accompanying drawings.

[0065] FIGS. 5 and 6 are a schematic diagram and an exploded perspective view of the electrical dust collection device 100 according to the present invention. As illustrated, the electrical dust collection device 100 of the present invention includes the charging part 1000 that applies charges to dust particles P introduced from the outside and the dust collection part 2000 that collects, by electric attraction, dust particles P′ charged by the charging part 1000.

[0066] Hereinafter, after first describing the charging part 1000 of the present invention, the dust collection part 2000 will be described.

[0067] FIGS. 7 to 10 are a perspective view, a partially enlarged view, an exploded perspective view, and a cross-sectional view taken along AA′ direction of the charging part 1000 according to the present invention, FIG. 11 is a partial schematic diagram of the charging part 1000 according to the present invention, FIGS. 12 and 13 each are partial exploded perspective views of the charging part 1000 according to the present invention, FIGS. 14 and 15 are views for describing another exploded perspective view of the charging part 1000 and a charging electrode 1130 according to the present invention, and FIG. 16 is another exploded perspective view of the charging part 1000 according to the present invention.

[0068] The charging part 1000 includes a first charging plate 1121, a second charging plate 1122, and a charging electrode 1130.

[0069] The first charging plate 1121 and the second charging plate 1122 are provided with a first charging hole 1121a and a second charging hole 1122a that penetrate to move dust therein, and are arranged in parallel spaced apart from each other by a predetermined distance in a dust movement direction and has a plate shape to apply a low voltage (the charging electrode 1130 has a high voltage).

[0070] In this case, the first charging plate 1121 and the second charging plate 1122 are formed so that the first charging hole 1121a and the second charging hole 1122a have the same shape, and the first charging hole 1121a and the second charging hole 1122a has a shape in which circles overlap with each other in a selected direction perpendicular to a direction in which dust particles are introduced. That is, the first charging plate 1121 is formed in a shape in which the plurality of first charging holes 1121a are connected, and a portion where circumferential surfaces of the first charging holes 1121a overlap with each other are curved, which is defined as a first overlapping curved portion 1121b. In addition, similar to the shape of the first charging hole 1121a, the second charging plate 1122 is formed in a shape in which the plurality of second charging holes 1122a are connected, and a portion where circumferential surfaces of the second charging holes 1122a overlap with each other are curved, which is defined as a second overlapping curved portion 1122b. In this way, in the electrical dust collection device 100 of the present invention, the charging part 1000 may be more easily manufactured more in various sizes by adjusting an overlap ratio and sizes of the first charging hole 1121a and the second charging hole 1122a, and may prevent unnecessary abnormal charge phenomenon from occurring due to a pointed shape as the first overlapping curved portion 1121b and the second overlapping curved portion 1122b are formed. In addition, an aperture ratio increases compared to the related art, and a loss of air pressure while passing through the charging part 1000 may be minimized.

[0071] On the other hand, the first charging plate 1121 and the second charging plate 1122 may each be formed using a single plate (see FIG. 13), and the first charging plate 1121 and the second charging plate 1122 may each be divided into a plurality of members (see FIG. 12). As illustrated in FIG. 12, when the first charging plate 1121 and the second charging plate 1122 are each divided into a plurality of members, it is possible to reduce material cost compared to using a single plate, and more easily perform assembling by using a charging frame 1110 to be described below.

[0072] The charging electrode 1130 includes charging pins 1131 that protrude from centers of the first charging hole 1121a formed in the first charging plate 1121 and the second charging hole 1122a formed in the second charging plate 1122 to apply charges to the dust particles.

[0073] A pointed end portion of the charging pin 1131 is positioned at radial centers of the first charging hole 1121a and the second charging hole 1122a, and exists in a region between the first charging plate 1121 and the second charging plate 1122 in a movement direction of air.

[0074] Also, the charging electrode 1130 is provided with the plurality of charging pins 1131, and the plurality of charging pins 1131 are integrally formed by an electrode rod 1132.

[0075] The charging electrode 1130 is configured to be elongated in the first charging hole 1121a (and the second charging hole 1122a continuously formed by the second charging plate 1122) continuously formed by the first charging plate 1121, the charging pin 1131 applies a voltage to the dust particles introduced into the first charging hole 1121a and the second charging hole 1122a, and the electrode rod 1132 connects the charging pins 1131. In this case, it is preferable that the charging electrode 1130 is formed using one metal plate. In this way, in the charging part 1000 of the present invention, as compared with the form in which the plurality of charging pins 1131 are individually assembled to the electrode rod 1132 and are used, the charging pins 1131 may be formed at accurate positions and the production cost and required time may be reduced. In particular, in the charging electrode 1130 of the present invention, the plurality of electrode pins may be provided in one electrode rod 1132 to form one line, such that the assembly manhour and material cost may be reduced and the electrical dust collection device 100 having stable charging performance may be manufactured. In this case, the charging electrode 1130 may be formed by processing the plate in a stamping or etching manner. In this way, in the charging part 1000 of the present invention, a process of welding individual charging pins 1131, or the like is not required, such that the time and cost required for manufacturing the electrical dust collection device may be reduced and the durability may be more increased. In addition, the charging pins 1131 may be accurately positioned at the centers of the overlapping circles forming the charging holes to further increase the charging efficiency. In addition, in the charging part 1000 of the present invention, as illustrated in FIG. 11, a corona discharge phenomenon is uniformly induced by the charging pin 1131 and the first charging plate 1121 and the second charging plate 1122, so the charging effect may be more increased.

[0076] Also, the charging part 1000 includes a charging frame 1110.

[0077] The charging frame 1110 is a portion on which the first charging plate 1121, the second charging plate 1122, and the charging electrode 1130 are mounted, and is formed in a frame shape.

[0078] In addition, the charging frame 1110 may include a first fixed frame 1111 for fixing the first charging plate 1121 and a second fixed frame 1112 for fixing the second charging plate 1122.

[0079] First, the first fixed frame 1111 is configured to fix the first charging plate 1121, and may be integrally formed with the charging frame 1110. The first fixed frame 1111 is provided with a first hollow portion 1111a corresponding to the first charging hole 1121a of the first charging plate 1121.

[0080] The method of fixing the first fixed frame 1111 and the first charging plate 1121 may be made in various ways, and the first fixed frame 1111 and the first charging plate 1121 has a structure that may be assembled and detached, and thus, may increase assembly property and may be inspected and replaced. As an example, one of the first fixed frame 1111 and the first charging plate 1121 may be provided with a first fastening protrusion 1111b, and the other thereof may be provided with a first fastening groove 1121c corresponding to the first fastening protrusion 1111b, so the first fixed frame 1111 and the first charging plate 1121 may be fixed to each other. FIG. 10 illustrates an example in which the first fixed frame 1111 may be provided with the first fastening protrusion 1111b and the first charging plate 1121 may be provided with the first fastening groove 1121c, and vice versa.

[0081] In addition, the second fixed frame 1112 is provided with a second hollow portion 1112a corresponding to the second charging hole 1122a of the second charging plate 1122. In this case, the method of fixing the second fixed frame 1112 and the second charging plate 1122 may also be made in various manners. As an example, one of the second fixed frame 1112 and the second charging plate 1122 may be provided with a second fastening protrusion 1112b, and the other thereof may be provided with a second fastening groove 1122c corresponding to the second fastening protrusion 1112b, so the second fixed frame 1112 and the second charging plate 1122 may be fixed to each other. FIG. 10 illustrates an example in which the second fixed frame 1112 may be provided with the second fastening protrusion 1112b and the second charging plate 1122 may be provided with the second fastening groove 1122c, and vice versa.

[0082] Meanwhile, the first fixed frame 1111 and the second fixed frame 1112 may be assembled and fixed to each other. In more detail, the first fixed frame 1111 and the second fixed frame 1112 are provided with a first fastening part 1111c and a second fastening part 1112c for fastening that respectively protrude in a direction facing each other, and the first charging plate 1121 and the second charging plate 1122 are provided with a hollow third fastening groove 1121d and fourth fastening groove 1122d through which the first fastening part 1111c and the second fastening part 1112c, respectively, penetrate. The first fastening part 1111c and the second fastening part 1112c are respectively formed in the first fixed frame 1111 and the second fixed frame 1112 to be assembled, and are provided to maintain a separation distance of the first charging plate 1121 and the second charging plate 1122.

[0083] Meanwhile, the second fixed frame 1112 may have a shape including a plurality of members when the second charging plate 1122 is divided into a plurality of pieces (see FIG. 16).

[0084] Describing the assembly of the charging part 1000 of the present invention, after the first charging plate 1121 and the first fixed frame 1111 are assembled, and the second charging plate 1122 and the second fixed frame 1112 are assembled, the first fastening part 1111c and the second fastening part 1112c are fastened.

[0085] In addition, the first fastening part 1111c and the second fastening part 1112c may serve not only to fix the first charging plate 1121 and the second charging plate 1122, but also to remove gaseous materials. The first fastening part 1111c and the second fastening part 1112c may have a form in which they are formed integrally with the first and second fixing plates, respectively, and then, attached or coated with a functional catalyst material capable of removing the gaseous materials. In addition, the first fastening part 1111c and the second fastening part 1112c may be made of a functional catalyst material and connected to the first and second fixing plates. In this case, the functional catalyst material is defined as a material having one of the functions of decomposing, adsorbing, and removing gas to prevent odor-causing gas or ozone from being introduced into the vehicle.

[0086] In addition, as illustrated in FIGS. 8 to 10, in the charging part 1000 of the present invention, a connection frame 1113 that is configured to fix the charging electrode 1130 may be further included in the charging frame 1110. The connection frame 1113 has both ends fixed to the charging frame 1110 to seat the charging electrode 1130, and is provided with an opening 1113a whose predetermined region is opened so that the charging pin 1131 of the charging electrode 1130 is exposed. That is, in the form illustrated in FIGS. 8 to 10, the charging electrode 1130 is directly seated on the connection frame 1113. In this case, it is preferable that the connection frame 1113 is provided with a first protrusion support portion 1116 supporting both surfaces of the electrode rod 1132. Two or more first protrusion support portions 1116 may be formed in a longitudinal direction of the electrode rod 1132 so as to easily support the electrode rod 1132 and be easily mounted, and may alternately support both surfaces of the electrode rod 1132 in a state where they are spaced apart from each other by a predetermined distance in the longitudinal direction.

[0087] In addition, as illustrated in FIGS. 14 and 15, in the charging part 1000 of the present invention, as a configuration for fixing the charging electrode 1130, the charging electrode fixing member 1140 and the connection frame 1113 may be used.

[0088] The charging electrode fixing member 1140 is a portion in which a fixed groove 1141 in which the charging electrode 1130 is seated is formed, and the fixed groove 1141 may be provided with a second protrusion support 1142 that supports both surfaces of the electrode rod 1132. Two or more second protrusion support portions 1142 may be formed in a longitudinal direction of the electrode rod 1132 so as to easily support the electrode rod 1132 and be easily mounted, and may alternately support both surfaces of the electrode rod 1132 in a state where they are spaced apart from each other by a predetermined distance in the longitudinal direction. In this case, it is preferable that the charging electrode fixing member 1140 is provided with a first corresponding portion 1143 in which a predetermined region of the fixed groove 1141 protrudes or is recessed so that the charging electrode 1130 is seated at an accurate position, and the charging electrode 1130 is provided with a second corresponding portion 1133 having a shape corresponding to the first corresponding portion 1143. In FIG. 15, an example in which the first corresponding portion 1143 has a form in which it protrudes and the second corresponding portion 1133 has a form in which the protruding first corresponding portion 1143 may be inserted thereinto is illustrated. In this case, the connection frame 1113 is a portion on which the charging electrode fixing member 1140 is seated, and is formed long so that both ends thereof are fixed to the charging frame 1110. In this case, the connection frame 1113 is provided with the opening 1113a whose predetermined region is opened to expose the charging pin 1131 of the charging electrode 1130.

[0089] That is, the charging part 1000 of the present invention may have a form in which the connection frame 1113 is formed to fix the charging electrode 1130, but as illustrated in FIGS. 8 to 10, the charging electrode 1130 is directly seated on the connection frame 1113, or the charging electrode 1130 may be first fixed to the charging electrode fixing member 1140, and the charging electrode fixing member 1140 may be seated on the connection frame 1113. As described above, in the charging part 1000 of the present invention, it is possible to increase productivity by using the charging electrode 1130 in which the charging pin 1131 and the electrode rod 1132 are integrally formed.

[0090] On the other hand, as described above, the electrical dust collection device 100 of the present invention includes the charging part 1000 and the dust collection part 2000 that collects, by the electric attraction, the dust particles charged by the charging part 1000. That is, as illustrated in FIG. 5, when the dust particles P pass through the charging part 1000, the dust particles P become charged dust particles P′ by the corona discharge (CD) phenomenon, and are collected by the dust collection part 2000.

[0091] In this case, as illustrated in FIG. 14, the dust collection part 2000 may include a filter type in which only air passes and dust particles are collected. In addition, various configurations capable of collecting the charged dust particles may be used.

[0092] In particular, the electrical dust collection device 100 of the present invention may increase the assembly property and productivity, may generate a low voltage in the first charging plate 1121 and the second charging plate 1122, respectively, thereby increasing the performance of charging dust, and operate the charging part 1000, thereby further reducing the effect of electric noise on the adjacent dust collection parts 2000.

[0093] For example, in the above-described exemplary embodiment, it has been described that the tip of the charging pin 1131 is disposed in the center between the first charging plate 1121 and the second charging plate 1122, but the tip of the charging pin 1131 may be disposed to be biased toward the charging plates 1121 and 1122 close to the direction in which the wind is introduced depending on a moving speed of the introduced dust, that is, a speed of wind. This is considering the movement of dust particles by wind.

[0097] The plurality of first dust collection plates 2121 are arranged in parallel spaced apart from each other by a predetermined distance.

[0098] The first connection portion 2122 is continuously formed at one side of both end portions of the plurality of first dust collection plates 2121 to electrically connect the first dust collection plates 2121 in series.

In the dust collection part 2000 of the present invention, the first connection portion 2122 may also be continuously formed on a lower side in a height direction, which is the other side of both end portions of the first dust collection plate 2121.

[0099] The first dust collection part 2120 may be manufactured in a form including the first dust collection plate 2121 and the first connection portion 2122 as described above by various methods. As illustrated in FIG. 20, the first collection plate 2121 and the first connection portion 2122 are manufactured using a single sheet, thereby increasing the productivity. In more detail, after a single sheet made of a conductive material and a dielectric material surrounding the conductive material is manufactured as illustrated in FIG. 20A and bent as illustrated in FIG. 20B, except for the region forming the first connection portion 2122, as illustrated in FIG. 20C, certain regions of the sheet are bonded to each other to form the first dust collection plate 2121. That is, two portions a1 and a2 of the sheet are bonded to each other to form one first dust collection plate 2121. In a single sheet, region a1, region a2, and region b are repeated and the region a1, the region a2, and the region b are again repeated to form a first dust collection plate 2121 and a first connection portion 2122 repeatedly. In this case, the sheet is formed in a form in which the conductive material is coated with the dielectric material and the conductive material is surrounded by the dielectric material, and the conductive material may be various materials such as a carbon sheet having electrical conductivity, and the dielectric material may be a thin film of plastic or the like. In addition, a conductive material of a predetermined region may be exposed at the end portion of the sheet to form a first electrode tab 2123 for a power supply connection.

[0100] In addition, the dust collection part 2000 of the present invention includes the second dust collection part 2220 to which a high voltage is applied together with the first dust collection part 2120.

[0101] The second dust collection part 2220 may be formed in the same shape as the first dust collection part 2120 (see the shapes shown in FIGS. 21 to 25), and includes a second dust collection plate 2221 and a second dust collection part 2220. In more detail, the plurality of second dust collection plates 2221 are arranged in parallel spaced apart from each other by a predetermined distance. The second connection portion 2222 is continuously formed at the other side of both end portions of the second dust collection plates 2221 to electrically connect the adjacent second dust collection plates 2221 in series. In this case, the second dust collection part 2220 is fitted into the first dust collection part 2120 so that the first dust collection plate 2121 and the second dust collection plate 2221 are alternately arranged to face each other, but is arranged to be not in contact with the first dust collection part 2120. That is, the first dust collection plate 2121 and the second dust collection plate 2221 are alternately arranged to be spaced apart from each other by a predetermined distance, and when the first connection portion 2122 of the first dust collection part 2120 is positioned on the upper side in the height direction, the second connection portion 2222 of the second dust collection part 2220 is positioned on the lower side in the height direction.

[0102] When a high voltage is applied to the first dust collection part 2120 and the second dust collection part 2220, an electric field is formed therebetween, and cationized dust particles are absorbed and collected on the surface of the first dust collection part 2120 and the second dust collection part 2220 by an electric field as air containing dust particles anionized or cationized by the charging part 100 passes between the first dust collection plate 2121 and the second dust collection plate 2221 (see FIG. 5).

[0103] The second dust collection plate 2221 and the second connection portion 2222 of the second dust collection part 2220 are also manufactured using a single sheet in the same manner as illustrated in FIG. 20 to further increase the productivity, and may be a form in which a conductive material of a predetermined region may be exposed to form a second electrode tab 2223 for power connection at the end portion of the sheet.

[0104] Therefore, the dust collection part 2000 of the present invention may use the connection portion continuously formed at one side of the plurality of dust collection plates, thereby increasing the productivity, and may increase the electrical stability, thereby further increasing the dust collecting performance. In particular, according to the present invention, the dust collection part 2000 may be simply manufactured in a form in which dust collection parts are joined to each other by using a single sheet except for an area in which a connection portion is formed, may not require an individual assembly process for a power supply connection to further increase productivity, and may be easily assembled.

[0105] In addition, the second dust collection part 2220 includes the second dust collection plate 2221 and the second connection portion 2222, and as illustrated in FIGS. 17 to 19, the second connection portion 2222 may be alternately formed on both end portions of the second dust collection plate 2221. In this case, the second dust collection plate 2221 and the second connection portion 2222 may be formed by bending a single sheet.

[0106] Meanwhile, the dust collection part 2000 of the present invention may include a first fixing member 2310 and a second fixing member 2320.

[0107] The first fixing member 2310 includes a first support 2311 elongated in a longitudinal direction which is a stacking direction of the first dust collection plate 2121 and the second dust collection plate 2221, and fixes a position of the first dust collection plate 2121.

[0108] The second fixing member 2320 includes a second support 2321 elongated in the longitudinal direction which is the stacking direction of the first dust collection plate 2121 and the second dust collection plate 2221, and fixes a position of the second dust collection plate 2221.

[0109] In order to form the first fixing member 2310 and the second fixing member 2320, the first dust collection plate 2121 is provided with a first insertion groove 2124 in which the first support 2311 of the first fixing member 2310 is inserted and fixed to one side in a width direction and provided with a first cut groove 2125 in which the second support 2321 of the second fixing member 2320 is positioned at the other side in the width direction, and the second dust collection plate 2221 is provided with a second cut groove 2225 in which the first support 2311 of the first fixing member 2310 is positioned on one side in the width direction, and provided with a second insertion groove 2224 in which the second support 2321 of the second fixing member 2320 is inserted and fixed to the other side in the width direction.
