Description

Technical field

[0001] Herein lies an electrification device for an electric dust collector, and in particular an electrification device for an electric dust collector, which helps to improve particle removal efficiency in a channel and a limited flow space, and which has a stable structure. background

[0002] A particle removal process generally involves two types of procedures: electrification and dust collection. In these processes, dust particles are electrified, and the electrified dust particles are collected using a dust collection filter.

[0003] One method for collecting dust includes physical collection with nonwoven fabric, electrical collection with a dielectric filter, and applying electrostatic force to a filter for physical dust collection with an electrostatic nonwoven fabric.

[0004] An electrification process includes diffusion-based electrification, electrification based on an electric field, and hybrid electrification (diffusion and electrification based on an electric field).

[0005] Electrification based on an electric field is effective in collecting large particles, and diffusion-based electrification is effective in collecting small particles.

[0006] In this regard, KR 10 2020 0 009 889 A discloses a structure for fixing a conductive microfiber and a cable to an installation frame which is arranged in and holds a main body frame.

[0007] In a configuration disclosed in KR 10 2020 0 009 889 A, an installation opening into which a conductive microfiber and a cable are inserted is formed on one of the two lateral surfaces of the installation frame, and the conductive fiber and the cable are inserted through the installation opening in a horizontal direction and press-fitted into the installation frame and coupled to it.

[0008] In the electrification device for an electric dust collector according to KR 10 2020 0 009 889 A, a lateral surface of the mounting frame is at least partially open to form the installation opening, and the microfiber and cable are press-fitted and coupled in the horizontal direction. If excessive force is applied to the microfiber and cable during the coupling process, damage to the mounting frame is highly likely. Specifically, the conductive microfiber is positioned at a predetermined distance from both fixed ends of the mounting frame, and the press-fit coupling force is applied in a direction perpendicular to the direction in which the mounting frame extends. Consequently, if a coupling force of even a relatively small magnitude is applied, the mounting frame will inevitably be damaged.

[0009] In the electrification device for an electric dust collector according to KR 10 2020 0 009 889 A, a lateral surface of the mounting frame is at least partially open to form the installation opening. Consequently, the rigidity of the mounting frame itself is considerably reduced, the mounting frame is easily broken or damaged by a relatively small external force during operation of the electrification device, and it is highly likely that the conductive microfiber will escape from a predetermined position. As a result, the electrification efficiency and the discharge efficiency of the conductive microfiber decrease considerably.

[0011] The present invention relates to an electrification device for an electric dust collector in which a discharge tip can be installed on a frame by means of an additional tip holder, which holds the discharge tip and a high-voltage cable in order to prevent escape of the discharge tip, which may be caused by vibrations or an external force, thereby ensuring the improvement of the electrification efficiency and the discharge efficiency.

[0012] The present disclosure also relates to an electrification device for an electric dust collector, in which the electrification continues to take place using the discharge tip and an earthing electrode, and the discharge tip can be spaced a predetermined distance from the earthing to maintain the discharge, thereby preventing a reduction in the discharge current as far as possible.

[0016] According to the present disclosure, a coupling structure is provided in which a discharge tip is exposed to the outside and the high voltage tip can be easily mounted with the fixed discharge tip.

[0017] According to the present disclosure, a coupling structure is provided in which a high-voltage cable can be connected and coupled with multiple discharge peaks without being exposed to the outside.

[0018] According to the present disclosure, an electrification device is provided in which a grounding network can be arranged in a direction opposite to a direction in which the discharge tip generates ions, thereby ensuring an improvement in the collection efficiency. Beneficial effect

[0019] In the electrification device for an electric dust collector according to the present disclosure, a discharge tip can be held firmly by a tip holder, thereby ensuring the improvement of the electrification efficiency and the discharge efficiency.

[0020] In the electrification device for an electric dust collector according to the present disclosure, the stiffness of a frame can be improved by a tip support, thereby maintaining the strength of the frame at a predetermined level or above despite a reduction in the size of the electrification device.

[0021] In the electrification device for an electric dust collector according to the present disclosure, the space in which a high-voltage cable is installed can be minimized by using a cable holder that holds the high-voltage cable, thereby reducing manufacturing costs.

[0022] In the electrification device for an electric dust collector according to the present disclosure, a reduction of the discharge current can be prevented as far as possible by an earthing network, and the ion redistribution can be improved.

[0032] An electrification device for an electric dust collector 100 according to embodiments is described below with reference to the accompanying drawings.

[0033] An overall structure of an arrangement which forms the electrification device for an electric dust collector 100 and a vehicle air conditioning system 1 according to an embodiment is described with reference to Fig. 1, Fig. 2 to Fig. 3. Briefly described, and a structure of each arrangement is briefly described.

[0034] Fig. Figure 1 is a perspective view showing an electrification device for an electric dust collector 100 according to an embodiment and a vehicle air conditioning system 1 in which the electrification device for an electric dust collector 100 is installed.

[0035] As in Fig. As shown in Figure 1, the electrification device for an electric dust collector 100 can be installed in the vehicle air conditioning system 1 according to one embodiment.

[0036] However, the position of the electrification device for an electric dust collector may not be restricted, and the electrification device for an electric dust collector can be applied to various types of air conditioners used in buildings and homes, air purifiers, and the like. An electrification device for an electric dust collector 100, installed in a vehicle air conditioner 1, is described below as an example.

[0037] The vehicle air conditioning system 1 can comprise a main body 11, 15, which forms an outer shell. The main body can comprise an intake main body 11, on which an inlet 20 is formed, and a discharge main body 15, on which an outlet 30 is formed.

[0038] The suction main body 11 and the discharge main body 15 can be connected to each other to allow the air to flow.

[0039] Several inlets 20 and several outlets 30 can each be formed on the suction main body 11 and the delivery main body 15.

[0040] The inlet 20 can comprise an inner inlet 21 and an outer inlet 22. The inner inlet 21 can be an inlet through which air from a vehicle equipped with the vehicle air conditioning system 1 flows into the main body 11. The outer inlet 22 can be an inlet through which air from outside the vehicle flows into the main body 11.

[0041] The outlet 30 can include a front outlet 31 and a defrost outlet 32. The front outlet 31 can be an outlet through which air emitted from the main body 11 flows into the vehicle.

[0042] The defrosting outlet 32 ​​can be an outlet through which air emitted from the main body 11 flows to a window of the vehicle.

[0043] Furthermore, the vehicle air conditioning system 1 may include a (not shown) fan, a (not shown) heat exchanger and similar components installed in the main body 11, 15.

[0044] The vehicle air conditioning system 1 can further comprise a flap (not shown) which selectively opens the multiple inlets 20 and the multiple outlets 30. For example, the flap can open any one of the inner inlet 21 and the outer inlet 22 and close the other.

[0045] Furthermore, the flap can open at least one of the several outlets 30.

[0046] The vehicle air conditioning system 1 can be equipped with an electrification device for an electric dust collector 1000 and a collection device 2000.

[0047] The electrification device for an electric dust collector 1000 can electrify foreign substances, such as dust particles and the like, in the air. Furthermore, the collection device 2000 can collect the dust particles and the like that electrified by the electrification device for an electric dust collector 1000 and remove the dust particles and the like from the air.

[0048] The electrification device for an electric dust collector 1000 may include an electrification module equipped with a high-voltage spike and a conductive plate, which are described below.

[0049] The high-voltage peak can be supplied with a high voltage, and the conductive plate can be connected to a grounding electrode. Consequently, the electrification device for an electric dust collector can generate 1000 ions in the air and create an electric field.

[0050] In this case, the conductive plate can generate an electric field as a result of creating an electrical potential difference between the conductive plate and the high-voltage peak. A detailed configuration of the electrification device for an electric dust collector is described below with reference to Fig. 2 and their subsequent drawings described.

[0051] The collection device 2000 can be a type of filter that collects particles that are electrified by the electrification device for an electric dust collector 100, and can be made from a variety of materials.

[0052] For example, the collection device 200 can be implemented as a porous fiber filter, such as a nonwoven fabric or similar material. Furthermore, a conductive material can be applied to, coated upon, or attached to a surface of the collection device 200.

[0053] Based on the foregoing feature, dust particles and similar substances in the air passing through the electrification device for an electric dust collector 1000 can combine with ions generated by the electrification device for an electric dust collector 1000 and can be electrified. The electrified dust particles and similar substances can then be collected in the electrification device for an electric dust collector 1000 or the collection device 2000.

[0054] The electrification device for an electric dust collector 1000 according to one embodiment can be provided as a single device alongside the collection device 2000.

[0055] In particular, the electrification device for an electric dust collector 1000 and the collection device 2000 can be manufactured and distributed using various manufacturing and distribution methods. Alternatively, the electrification device for an electric dust collector 1000 and the collection device 2000 can be coupled together by an additional coupling element and the like, and can be mounted on the vehicle air conditioning system 1.

[0056] The vehicle air conditioning system 1 can, as in Fig. Figure 1 shows a dust collector installation part 13 in which the electrification device for an electric dust collector 1000 and the collection device 2000 are installed. In particular, the dust collector installation part 13 can be located near the inlet 20 on the main suction body 11.

[0057] The dust collector installation part 13 can be arranged below the airflow with respect to the direction in which the air introduced through the inlet 20 flows. Consequently, air introduced through the inlet 20 passes through the electrification device for an electric dust collector 100 before passing through the collection device 200.

[0058] Furthermore, the vehicle air conditioning system 1 can be equipped with a fan installation part 12 in which a fan is installed. In particular, the fan installation part 12 can be located near the inlet 20 on the main suction body 11. The fan installation part 12 can be positioned below the dust collector installation part 13 with respect to the airflow direction.

[0059] This means that the inlet 20, the dust collector installation part 13, and the fan installation part 12 can be arranged sequentially on the main flow body 12 in the direction of airflow. Consequently, the air introduced through the inlet 20 can pass sequentially through the electrification device for an electric dust collector 1000, the collection device 2000, and the fan, and can flow to the discharge main body 15.

[0060] In this case, the electrification device for an electric dust collector 1000 and the collection device 2000 can each be installed in the dust collector installation part 13. In particular, the collection device 2000 can be arranged further downstream than the electrification device for an electric dust collector 1000 with respect to the airflow direction. Thus, the air introduced through the inlet 20 can pass through the electrification device for an electric dust collector 1000 and the collection device 2000 sequentially.

[0061] The electrification device for an electric dust collector 1000 can be installed in the dust collector installation part 13 in a state where it is mounted on the collection device 2000. That is, the electrification device for an electric dust collector 1000 and the collection device 2000 can be mounted on the dust collector installation part 13 in such a way that the electrification device for an electric dust collector and the collection device overlap, as shown.

[0062] Since the electrification device for an electric dust collector 1000 and the collection device 2000 are installed individually and as described above, the electrification device for an electric dust collector and the collection device can be handled separately. For example, a user can disconnect the collection device 2000 from the vehicle air conditioning system 1 and can replace and wash the collection device.

[0063] The replacement cycle for the electrification device of an electric dust collector 1000 can differ from the replacement cycle for the collection device 2000. Since the collection device 2000 generally generates a larger quantity of dust particles and similar debris, its replacement cycle can be shorter than that for the electrification device. This allows the user to replace only the collection device 2000 without needing to replace the entire electrification device of the electric dust collector 1000, thus significantly improving user convenience.

[0064] Fig. Figure 2 is a perspective view schematically showing an electrification device for an electric dust collector according to one embodiment, and Fig. Figure 3 is an exploded view showing the electrification device for an electric dust collector in Fig. 2 shows schematically.

[0065] Fig. Figure 3 is an exploded view showing an electrification module 1100 and a cover module 1200 separated from each other in the electrification device for an electric dust collector 1000.

[0066] In particular, the electrification device for an electric dust collector 1000 according to one embodiment can comprise an electrification module 1100, which electrifies foreign substances, such as dust particles and the like, contained in air through which the electrification device for an electric dust collector passes, and a cover module 1200, which supplies a high voltage to the electrification module 1100.

[0067] The electrification module 1100 can be a part that is inserted into the dust collector installation part 13 and is directly exposed to flowing air as a whole, and the cover module 1200 can be a part that serves as a cap that is coupled to an open part of the dust collector installation part 13 into which the electrification module 1100 is inserted and that closes the open part.

[0068] The cover module 1200 can include a cover part 1210, which serves as a cap, and a high-voltage supply (not shown) contained within the cover part 1210, which generates a high voltage to be supplied to the electrification module 1100. A high-voltage cable for supplying voltage to the discharge tip 1131 of the high-voltage tip 1130 and a grounding cable for grounding a conductive plate, described below, can be electrically connected to the (not shown) high-voltage supply.

[0069] A projecting surface, which projects at least partially forward, can be formed on a front surface 1211 of the cover part 1210. A space in which the high-voltage supply is housed can be formed on a rear side of the projecting surface 1212.

[0070] The cover part 1210 can be provided integrally or separately with a main connector 1213 on its front surface 1211 to allow power to be supplied from outside to the high voltage supply.

[0071] Furthermore, the cover module 1200 can be provided on its sides with a hook-shaped bracket 1214 and a retaining projection 1215 for detachable coupling with the dust collector installation part 13.

[0072] The electrification module 1100 and the cover module 1200 can be detachably coupled to each other by means of a bolt. In particular, a connecting part 1111b, which is formed on an upper frame 1110 of the electrification module 1100, can be coupled to the cover part 1210 by means of the bolt in a state in which it is coupled to a rear surface of the cover part.

[0073] Although not shown, a (not shown) plate-shaped sieve can be arranged below the electrification module 1100 and can collect electrified dust particles at least partially.

[0074] A technical configuration and an organic coupling structure of an electrification module according to one embodiment are described below with reference to Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13 to Fig. 14 specifically described.

[0075] Fig. Figure 4 is a first exploded view showing an electrification module in the electrification device for an electric dust collector in Fig. 3 shows schematically. Fig. Figure 5 is a second exploded view showing an electrification module in the electrification device for an electric dust collector in Fig. 3 shows schematically. Fig. Figure 6 is a lower perspective view showing an upper frame in the electrification module in Fig. 4 shows schematically.

[0076] In particular, the electrification module 1100 can comprise an upper frame 1110, a conductive plate 1120, a high-voltage peak 1130 and a lower frame 1140.

[0077] Fig. Figure 4 is an exploded view in which only the top frame 1110 is separated, and Fig. Figure 5 is an exploded view in which the conductive plate 1120, the lower frame 1140 and an earthing network 1150 are additionally separated.

[0078] The lower frame 1140 can be stacked on the grounding network 1150, and the conductive plate 1120, the high voltage spike 1130 and the upper frame 1110 can be stacked successively on the lower frame 1140.

[0079] The conductive plate 1120, the high-voltage spike 1130 and the upper frame 1110 can be stacked one after the other on the lower frame 1140.

[0080] This means that the conductive plate 1120 and the high-voltage tip 1130 can be mounted on and held by the lower frame 1140, and the upper frame 1110 can be detachably coupled to the lower frame 1140, while the conductive plate 1120 and the high-voltage tip 1130 are covered, so that the discharge tip is exposed to the outside.

[0081] The upper frame 1110 can include an upper outer frame 1111 and an upper inner frame 1112.

[0082] The upper outer frame 1111 can correspond to an outer part and can as a whole have a predetermined height and a rectangular shape.

[0083] The upper outer frame 111 can have a cross-section whose lower end is open and which overall has a “⊏” shape. Furthermore, a conductive plate 1120, arranged on an outer surface, can be accommodated in a “⊏”-shaped interior of the upper outer frame 1111.

[0084] Furthermore, the high-voltage cable 1132 and a cable holder 1134 of the high-voltage peak 1300 can be accommodated in an interior space of the upper outer frame 1111, in which the conductive plate is not located.

[0085] A lower frame coupling part for coupling with the lower frame 1140 can be formed on the upper outer frame 1111, and the lower frame coupling part can be implemented as several hook coupling parts 1111a. The hook coupling part 1111a can be used to detachably couple the upper frame 1110 to the lower frame 1140 and can be designed to correspond to the coupling hook 1141a of the lower frame 1140.

[0086] Furthermore, a plate coupling element 1111c of the conductive plate can be formed on the upper outer frame 1111. The coupling element 1111c of the conductive plate can be formed into a groove into which the conductive plate is inserted.

[0087] Additionally, as described above, a connecting part 1111b can be formed on the upper outer frame 1111 for coupling with the cover module 1200.

[0088] Furthermore, a cable holder coupling part 1111b can be formed on the upper outer frame 1111, and the cable holder 1134 can cover the cable holder coupling part 1111d and can be coupled to the cable holder coupling part 1111d.

[0089] The upper inner frame 1112 can be formed within the upper outer frame and can comprise a first upper inner frame 1112a and a second upper inner frame 1112b. The first upper inner frame 1112a can be used to cover the high-voltage peak, and the second upper inner frame 1112b can be used to cover the conductive plate.

[0090] The second upper inner frame 1112b can divide the interior of the upper outer frame into several electrification spaces.

[0091] Like the upper outer frame 1111, the first upper inner frame 1112a and the second upper inner frame 1112b can have a cross-section whose lower end is open and which overall has a “⊏” shape.

[0092] Fig. Figure 6 shows an example in which only the first upper inner frame 1112a has a “⊏”-shaped cross-section.

[0093] The high-voltage cable 1132, which supplies a voltage to the discharge tip 1131 of the high-voltage peak 1130, can be accommodated in the interior of the first upper inner frame 1112a.

[0094] An upper high-voltage peak body coupling part 1112a', 1112a'' can be formed on the first upper inner frame 1112a, and a high-voltage peak body 1133 of the high-voltage peak 1130 can be coupled to the high-voltage peak body coupling part 1112a', 1112a''.

[0095] An open part (1112a'1 and 1112a''1, which in Fig. 12 is shown), through which the discharge tip 1131 of the high-voltage peak 1300 passes, and an upper high-voltage peak body coupling part (1112a'2 and 1112a''2, which are shown in Fig. 12 are shown), with which the high-voltage peak body 1133 is coupled, can be formed on the upper high-voltage peak body coupling part 1112a', 1112a''.

[0096] Furthermore, the upper high-voltage peak body coupling part can comprise a first upper high-voltage peak body coupling part 1112a' and a second upper high-voltage peak body coupling part 1112a''.

[0097] The second upper high-voltage peak body coupling part 1112a'' can be arranged on a front side of the first upper high-voltage peak body coupling part 1112a' with respect to a direction of extension of the high-voltage cable 1132.

[0098] The high-voltage peak body can be coupled to the first upper high-voltage peak body coupling part 1112a', and the high-voltage peak body can be coupled to the second high-voltage peak body coupling part 1112a'' and can simultaneously cover the high-voltage peak body and the high-voltage cable 1132.

[0099] If a single first upper inner frame 1112a covers several of the high-voltage peak bodies 1133, the second upper high-voltage peak body coupling part 1112a'', which is formed on the front of the first upper high-voltage peak body coupling part 1112a' with respect to an extension direction of the high-voltage cable 1132, can be configured to correspond to a surface area in which the high-voltage peak body and the high-voltage cable 1132 are arranged such that they cover the high-voltage peak body and the high-voltage cable 1132 simultaneously.

[0100] The second upper inner frame 1112b can be arranged in such a way that the second upper inner frame is parallel to the first upper inner frame 1112a, and can be arranged inside the upper outer frame 1111.

[0101] The lower frame 1140 can include a lower outer frame 1141 and a lower inner frame 1142.

[0102] The lower outer frame 1141 can be designed to correspond to the upper outer frame 1111, and a hook 1141a, to enable the lower outer frame 1141 to be inserted into it and coupled to the hook coupling part 1111a of the upper outer frame, can be designed to project upwards.

[0103] A lower inner frame 1142 can be arranged within the lower outer frame 1141a, and several inner lower frames can be configured to correspond to several first upper inner frames 1112a.

[0104] A cable mounting groove 1142a and a lower high voltage peak body mounting part 1142b can be formed on the lower inner frame 1142.

[0105] The cable mounting groove 1142a can be used to mount the high voltage cable 1132 of the high voltage peak 1130, and the lower high voltage peak body mounting part 1142b can be used to mount the high voltage peak body 1133 1330 of the high voltage peak 1130.

[0106] A first lower high voltage peak body mounting part 1142b' and a second lower high voltage peak body mounting part 1142b'' can be formed on the lower high voltage peak body mounting part 1142b.

[0107] The high voltage spike body can be mounted on the first lower high voltage spike body mounting part 1142b', and the high voltage spike body and the high voltage cable 1132 can be mounted on the second lower high voltage spike body mounting part 1142b''.

[0108] This means that if the multiple high-voltage peak bodies 1133 are mounted on a single lower inner frame 1142, an additional cable mounting groove can be formed on the second lower high-voltage peak body mounting part 1142b'', which is formed on a front side with respect to the direction of extension of the high-voltage cable 1132.

[0109] Consequently, the high-voltage cable can extend safely to the high-voltage peak body, which is located on a rear side with respect to the extension of the high-voltage cable 1132.

[0110] Thus, according to one embodiment, the upper frame 1110 and the lower frame 1140 can define an exterior of the electrification module 1100 and can fix and hold the high-voltage peak 1130 and the conductive plate 1120 in a predetermined position.

[0111] For this purpose, the upper frame 1110 and the lower frame 1140 can be made of a non-conductive material, e.g., plastics. Furthermore, the upper frame 1110 and the lower frame 1140 can be formed into various shapes by injection molding or similar processes.

[0112] The grounding network 1150 can have the effect of properly distributing ions generated by the discharge peak of the high voltage peak 1300 and improving the service life of a filter.

[0113] Furthermore, depending on the shape of the grounding network 1150, the degree to which the grounding network attracts ions generated by the discharge peak can be adjusted. That is, if too many ions are generated by the discharge peak, the degree of attraction can decrease, and if too few ions are generated by the discharge peak, the degree of attraction can increase.

[0114] Since an output voltage drops through the grounding network, the single-pass efficiency can be improved as a result of ion redistribution.

[0115] Fig. Figure 7 is a perspective view showing a conductive plate at the high-voltage peak in Fig. 4 shows schematically. Fig. Figure 8 is an exploded view showing the conductive plate in Fig. 7 shows schematically.

[0116] As shown, the conductive plate 1120, together with the high-voltage spike 1130, can form an electric field. The conductive plate 1120 can be implemented as a metallic plate with a predetermined thickness, and a grounding cable 1135 can be connected to the conductive plate 1120. Consequently, an electrical potential difference can occur between the conductive plate 1120 and the discharge tip 1131 of the high-voltage spike 1130, and an electric field can be formed between them.

[0117] Furthermore, a high density of ions can be generated between the discharge tip 1131 and the conductive plate 1120.

[0118] Since the conductive plate 1120 can be provided as a flat plate with a predetermined width in the direction in which the discharge tips are stacked, the conductive plate 1120 can collect predetermined dust particles and the like. The conductive plate 1120 can be covered by the upper frame 1110 to prevent dust particles and the like from adhering directly to the conductive plate 1120.

[0119] The conductive plate 1120 can be arranged around the discharge tip 1131. In particular, the conductive plate 1120 can form a predetermined electrification space that surrounds a circumference of the discharge tip 1131. The electrification space can be closed off by the conductive plate 1120 in the direction in which the conductive plate surrounds the circumference of the discharge tip 1131 and can be open in an upward direction of the discharge tip 1131.

[0120] Furthermore, the conductive plate 1120 can form an electrification chamber with a rectangular column shape. The electrification chamber can, for example, be configured as a square column to unify the magnetic field and ion emission.

[0121] In this case, the discharge tip 1131 can be positioned in the center of the electrification space and can be configured to emit ions in a direction opposite to the airflow direction.

[0122] As described above, the electrification space can denote a space designed to surround a single discharge peak 1131. Consequently, the number of electrification spaces can correspond to the number of discharge peaks 1131.

[0123] In this embodiment, for example, a total of nine electrification chambers are provided. In this case, the discharge tip 1131 can be arranged in each of the electrification chambers or only in some of the electrification chambers.

[0124] In the illustrated embodiment, a total of five discharge peaks 1131 are arranged, and the number of discharge peaks 1131 provided can be adjusted depending on the required ion emission rate or airflow. For the sake of simplicity, a configuration in which a total of five discharge peaks 1131 are provided is described below.

[0125] The conductive plate portion 1120 can comprise several first plates 1121 and several second plates 1122. The first plate 1121 and the second plate 1122 can be arranged such that they intersect each other in an orthogonal direction.

[0126] The multiple first plates 1121 and the multiple second plates 1122 can be set up at regular intervals, and the first plate 1121 can be inserted into the second plate 1122 and coupled to it, so that the upper ends of the first plate 1121 and the second plate 1122 are arranged on the same flat surface.

[0127] A cable mounting part 1121a, a second plate insert part 1121b and an end decoupling part 1121c can be formed on the first plate 1121.

[0128] The cable mounting part 1121a can be used to mount the high-voltage cable 1132 to the high-voltage peak 1130. That is, the cable mounting part 1121a can be formed into a groove extending from the upper end of the first plate 1121. Since the high-voltage cable 1132, which supplies voltage to the discharge peak 1131, is mounted onto the cable mounting part 1121a with its groove shape, the electrification module 1100 can have a stable structure that prevents movement of the high-voltage cable 1132 caused by an external shock or pressure.

[0129] The second plate insert part 1121b can be formed into a slot extending from a lower end surface of the first plate 1121 to an upper section of the first plate.

[0130] The end decoupling element 1121c can be formed at both lateral ends of the first plate 1121 and can be used to insert and couple the second plate 1122, which is to be coupled to both lateral ends of the first plate 1121. The end decoupling element 1121c can be formed as a slot extending from a lower end surface of the first plate 1121 to an upper section of the first plate.

[0131] A first plate insertion part 1122a, an end decoupling part 1122b and an earthing pin mounting part 1122c can be formed on the second plate 1122.

[0132] The first plate insertion part 1122a can be formed into a slot extending from an upper end surface of the second plate 1122 to a lower section of the second plate, and the first plate 1121 can be inserted into the second plate from an upward direction in a downward direction.

[0133] The end decoupling element 1122b can be formed on both lateral ends of the second plate 1122 and can be formed as a slot extending from the upper end surface of the second plate 1122 to the lower section of the second plate. The first plate 1121 can be inserted into the second plate from the upward direction to the downward direction.

[0134] A grounding pin (in Fig. 9 shown by 1136), which is connected to the grounding cable 11135, can be inserted into the grounding pin mounting part 1122c and thus coupled.

[0135] With the above configuration, the conductive plate 1120 can be divided into individual electrification spaces by the first plate 1121 and the second plate 1122. Fig. Figure 7 shows nine electrification rooms as an example.

[0136] The first plate 1121 and the second plate 1122 can be integrally formed or manufactured and coupled separately.

[0137] Fig. Figure 9 is a perspective view showing a high-voltage spike in the electrification module in Fig. 4 schematically shows, Fig. 10 is a detailed view showing the high-voltage peak in Fig. 9 schematically shows, Fig. 11 is a cross-sectional view showing the high-voltage peak in Fig. 9 schematically shows, Fig. 12a and Fig. 12b are partial views showing an upper frame and a lower frame in the electrification module in Fig. 4. Show schematically, Fig. Figure 13 is a perspective view schematically showing a state in which a grounding cable of a high-voltage peak is coupled to a lower frame, and Fig. Figure 14 is a partial view showing a coupling structure of a grounding pin connected to the grounding cable in Fig. 13 is connected, as shown schematically.

[0138] The high voltage spike 1130 can, as shown, comprise a discharge spike 1131, a high voltage cable 1132, a high voltage spike body 1133, a cable holder 1134, a grounding cable 1135, a grounding terminal 1136 and a grounding connection spike 1137.

[0139] The discharge tip 1131 can include a discharge brush that directly induces a discharge. For example, the discharge brush can be made of multiple carbon fibers. The carbon fiber can be formed into a microfiber with a micrometer diameter. When a high voltage is applied to the carbon fiber via the high-voltage cable, a corona discharge can generate ions in the air.

[0140] Furthermore, the discharge tip 1131 can be positioned on the upper frame 1110 in such a way that it extends in an up-down direction, for example, in a direction opposite to the airflow direction F. Consequently, emitted ions can be emitted at a maximum level, and dust particles contained in the air can be uniformly electrified.

[0141] The discharge tip 1131 can be electrically connected to the high-voltage cable 1132 and can be held by the high-voltage tip body 1133.

[0142] The discharge tip 1131 can be fixed to the high-voltage cable 1132 by means of a thermo-contraction hose 1131'.

[0143] The discharge peak 1131 can include several discharge peaks and can include, as shown, the first to fifth discharge peaks 1131a, 1131b, 1131c, 1131c, 1131e.

[0144] The high-voltage peak body 1133 can be arranged between the upper frame 1110 and the lower frame 1140, and an upper section of the high-voltage peak body 1133 can be at least partially covered by the upper frame in a state in which the high-voltage peak body 1133 is mounted on the lower frame 1140.

[0145] Furthermore, the high-voltage tip body 1133 can be manufactured separately from the discharge tip 1131 and the high-voltage cable 1132 and coupled with the discharge tip 1131 and the high-voltage cable 1132, or it can be manufactured using an insert injection molding process in a state in which the discharge tip 1131 and the high-voltage cable 1132 are arranged in a mold.

[0146] The high-voltage spike body 1133 can be pressed and held by one body and the other body in a state in which the discharge spike 1131 and the high-voltage cable 1132 are at least partially inserted between one body and the other body, after one body and the other body have each been injection molded for the high-voltage spike body.

[0147] A pair of upper hook parts 1133a and a pair of lower hook parts 1133b, each having approximately the same shape and protruding, can be formed in an upper section and a lower section of the high-voltage spike body 1133.

[0148] The pair of upper hook parts 1133a and the pair of lower hook parts 1133b can each be spaced a maximum distance apart from the discharge tip 1131 to prevent the pair of upper hook parts 1133a and the pair of lower hook parts 1133b from coming into contact with the discharge tip 1131.

[0149] For example, the upper hook part 1133a can comprise a first upper hook 1133a' and a second upper hook 1133a''. The first upper hook 1133a' can be formed at one side end of the upper section of the high-voltage spike body 1133, and the second upper hook body 1133a'' can be formed at the other side end of the upper section of the high-voltage spike body 1133.

[0150] The lower hook part 1133b can be symmetrical to the upper hook part 1133a.

[0151] That is, the lower hook part 1133b can comprise a first lower hook 1133b' and a second lower hook 1133b''. The first lower hook 113b' can be formed at one side end of the lower section of the high-voltage spike body 1133, and the second lower hook 1133b'' can be formed at the other side of the lower section of the high-voltage spike body 1133.

[0152] The lower hook part 1133b can comprise the first lower hook 1133b', which is arranged at a rear end of the lower section of the high-voltage peak body 1133, and the second lower hook 1133b'', which is arranged at a front end of a lower section of the high-voltage peak body 1133.

[0153] The high-voltage tip body can be manufactured using the insert injection molding process in a state where the discharge tip and the high-voltage cable are arranged in one mold.

[0154] The grounding cable 1135 can be connected to a grounding terminal 1136 via a grounding connection tip 1137.

[0155] The grounding cable 1135 can, as in Fig. 13 shown, are held by the lower frame 1140 and are electrically connected to the earthing terminal 1136 by the earthing connection tip 1137.

[0156] The earthing connection tip 1137 can connect to the earthing terminal 1136, and the earthing terminal 1136 can be inserted into and coupled to an earthing pin mounting part 1122c formed on the second plate 122.

[0157] The high-voltage peak 1130 can be configured as described above. Coupling structures between the high-voltage peak 1130 and the upper frame 1110, and between the high-voltage peak and the lower frame 1140, are described below.

[0158] In particular, as in Fig. 12(a) shows a first upper high-voltage peak body coupling part 1112a' and a second upper high-voltage peak body coupling part 1112a'' formed on the upper frame 1110.

[0159] A discharge peak passage hole part 1112a'1 and an upper hook coupling part 1112a'2 can be formed on the first upper high voltage peak body coupling part 1112a'.

[0160] The discharge peak passage hole part 1112a'1 can be used to expose the discharge peak 1131 of the high voltage peak 1130 to the outside when the upper frame 1110 is coupled with the lower frame 1140 to cover the high voltage peak 1130.

[0161] The upper hook coupling part 1112a'2 can be used to insert and couple the pair of upper hook parts 1133a of the high-voltage peak body 1133 described above. For this purpose, the upper hook coupling part 1112a'2 can be configured as a through-hole corresponding to the upper hook part 1133a.

[0162] The upper hook coupling part 1112a'2 can be formed on both sides of the discharge tip passage hole part 1112a'1.

[0163] Furthermore, as in the case of the aforementioned upper first high-voltage peak body coupling part 1112a'', a discharge peak passage hole part 1112a''1 and an upper hook coupling part 1112a"2 can each be formed on the second upper high-voltage peak body coupling part 1112a".

[0164] A first lower high-voltage peak body coupling part 1141b' and a second lower high-voltage peak body coupling part 1141b" can be, as in Fig. 12(b) shown, formed on the lower frame 1140.

[0165] A lower hook coupling part 1141b'1, 1141b''1 can each be formed on the first lower high voltage peak body coupling part 1141b' and the second lower high voltage peak body coupling part 1141b''.

[0166] The lower hook coupling part 1141b'1, 1141b''1 can be used to insert and couple the pair of lower hook parts 1133b of the high-voltage peak body 1133 described above. For this purpose, the lower hook coupling part 1141b'1, 1141b''1 can be configured as a through-hole corresponding to the lower hook part 1133b.

[0167] Furthermore, the high-voltage cable 1132 can include the first to fifth cables 1132a, 1132b, 1132c, 1132d, 1132e and can be configured to connect electrically to the high-voltage supply.

[0168] If the first to fifth cables are configured to connect individually to the high-voltage supply, additional space is required to hold and protect the first to fifth cables (1132a, 1132b, 1132c, 1132d, 1132e), and a connection terminal must be installed individually on the high-voltage supply.

[0169] This means that the number or length of required cables may increase, and the sizes of the upper frame 1110 and the lower frame 1140, which cover the first to fifth cables (1132a, 1132b, 1132c, 1132d, 1132e), may increase.

[0170] To solve the problem, the electrification module 1100 according to the present disclosure can be provided with a cable holder 1134 to simplify a connection structure of the first to fifth cables (1132a, 1132b, 1132c, 1132d, 1132e).

[0171] The cable holder 1134 can have a cuboid shape with a left-right width that is greater than a top-bottom height and a front-back thickness.

[0172] A cable connection structure that branches a main cable 1132', one end of which electrically connects to the aforementioned high-voltage supply, into the first to fifth cables 1132a, 1132b, 1132c, 1132d, 1132e, can be concealed in the cable holder 1134 with the cuboid shape.

[0173] This means that the cable holder 1134 can protect and maintain a branch point or a contact point between the main cable 1132' and the first to fifth cables 1132a, 1132b, 1132c, 1132d, 1132e.

[0174] The other end of the main cable 1132', one end of which electrically connects to the high voltage supply, can pass through a lateral surface 1134d of the cable holder 1134 and extend into the cable holder 1134.

[0175] For example, the other end of the main cable 1132' can pass through and extend along the top side of a lateral surface 1134d of the cable holder 1134, as shown. Since only a single main cable 1132' connects to the high-voltage supply, the configuration of a connection part of the high-voltage supply can be simplified.

[0176] The other end of the main cable 1132', which extends into the cable holder 1134, can be branched into the first to fifth cables 1132a, 1132b, 1132c, 1132d, 1132e.

[0177] Of the first to fifth cables, the first to third cables 1132a, 1132b, 1132c can pass through the other lateral surface 1134c of the cable holder 1134, protrude to the outside of the cable holder 1134 and extend to the first to third discharge peaks 1131a, 1131b, 1131c, respectively.

[0178] The first to third cables 1132a, 1132b, 1132c, which supply a voltage to the first to third discharge peaks 1131a, 1131b, 1131c, which are set up on one side with respect to the cable holder 1134, can be configured to pass through and extend across the other lateral surface 1134c of the cable holder 1134.

[0179] The fourth and fifth cables 1132d, 1132e, which supply a voltage to the fourth and fifth discharge tips 1131d, 1131e, which are set up on one side of the cable holder 1134, can be configured to pass through and extend across the side surface 1134d of the cable holder 1134.

[0180] In order to minimize the front-back thickness of the cable holder 1134 in this case, positions where the first to third cables 1132a, 1132b, 1132c protrude can be arranged side by side in the top-bottom direction on the other lateral surface 1134c of the cable holder 1134, and positions where the main cable 1132c', the fourth cable and the fifth cable 1132d, 1132e protrude can be arranged side by side in the top-bottom direction on a lateral surface 1134d of the cable holder 1134.

[0181] With the above configuration, the same number of cables can be arranged on the other side surface 1134c and one side surface 1134d of the cable holder 1134. Consequently, the front-to-back thickness and height of the cable holder 1134 can be minimized and optimized, and the top-to-bottom height of the electrification module 1100 can be minimized.

[0182] If the third to fifth discharge tips 1131c, 1131d, 1131e are arranged with respect to one connection direction of the main cable 1132' on the other side of the cable holder 1134, the third to fifth cables 1132c, 1132d, 1132e can be configured to pass through one lateral surface 1134d of the cable holder 1134, and the main cable 1132' and the first and second cables 1132a, 1132b can be configured to connect through the other lateral surface 1134c of the cable holder 1134.

[0183] The cable holder 1134 can be manufactured using the insert injection molding process in a state in which the main cable 1132' is branched into the first to fifth cables 1132a, 1132b, 1132c, 1132d, 1132e.

[0184] A well-known technology in engineering, which relates to the present disclosure, can be applied to the structure in which the main cable 1132' branches into the first to fifth cables 1132a, 1132b, 1132c, 1132d, 1132e and is manufactured using the insert injection molding process. Consequently, the description relating thereto is omitted.

[0185] An upper surface 1134a and a lower surface 1134b of the cable holder 1134 can be accommodated in the upper frame 1110 and the lower frame 1140 in a state where the upper surface 1134a and the lower surface 1134b respectively make surface contact with the upper and lower frames. In order to minimize the length of the main cable 1132' in this case, the cable holder 1134 can be arranged near the cover module 1200, which houses the high-voltage supply.

[0186] A fixing projection 1134f can be formed on the upper surface 1134a of the cable holder 1134 and project towards the upper frame 1110, and an insertion hole corresponding to the fixing projection 1134f can be formed on the upper frame 1110.

[0187] Fig. Figure 9 shows an embodiment equipped with a single cable holder 1134. However, as shown in Fig. Figure 15 shows an embodiment configured which includes multiple cable holders.

[0188] As in Fig. As shown in Figure 15, a first cable holder 1134' and a second cable holder 1134" can be provided, and the first cable holder and the second cable holder can be spaced apart from each other, with the third discharge tip 1131c between them.

[0189] As the in Fig. The cable holders 1134 shown can conceal a cable connection structure for branching multiple cables in each of the first cable holder 1134' and the second cable holder 1134".

[0190] Furthermore, the first cable holder 1134' and the second cable holder 1134" can be reused in Fig. The 9 cable holders shown are configured to allow cables to be connected through a side surface of each of the cable holders.

[0191] However, the first cable holder 1134' and the second cable holder 1134" can allow a smaller number of cables to pass through the side surfaces of the cable holders than with the one in Fig. The cable holder shown in section 9 is connected to cable holder 1134.

[0192] In particular, the main cable 1132' can connect to a lateral surface of the first cable holder 1134', preferably a front surface of the first cable holder.

[0193] The main cable 1132' can be branched in the first cable holder 1134', the fourth cable 1132d and the fifth cable 1132e can project side by side in the top-bottom direction through one lateral surface of the first cable holder 1134', and an intermediate cable 1132f can project and extend through the other lateral surface of the first cable holder 1134'.

[0194] The intermediate cable 1132f, extending from the other lateral surface of the first cable holder 1134', can pass through a lateral surface of the second cable holder 1134" and extend into the second cable holder 1134".

[0195] The intermediate cable 1132f, which extends into the second cable holder 1820, can be branched into the first to third cables 1132a, 1132b, 1132c.

[0196] As shown, of the branched cables, the first cable 1132a and the second cable 1132b can protrude and extend side by side in the top-bottom direction from the other lateral surface of the second cable holder 1134", and the third cable 1132c can protrude and extend in the top-bottom direction next to the intermediate cable 1132f and from the other lateral surface of the second cable holder 1134".

[0197] With the above configuration, the number of cables connected to each of the lateral surfaces of the first cable holder 1134' and the second cable holder 1134" can be limited to 2 or fewer. Consequently, the height of the first cable holder 1134' and the second cable holder 1134" can be increased, and the top-to-bottom height of the electrification module 1100 can also be increased.

[0198] Fig. Figure 16 is a lower view showing the electrification module in Fig. 3 schematically shows, Fig. Figure 17 is a perspective view showing a grounding network extending from a lower frame in the electrification module in Fig. 16 is separated, schematically shows, and Fig. Figure 18 is a perspective view showing an earthing network coupling part in the lower frame. Fig. 17 schematically shows.

[0199] In the electrification module 110, the earthing network 1150 can be coupled to the lower frame 1140 in such a way that the earthing network is fixed to the lower frame as shown.
