Description

Electric dust collector {ELECTRIFICATION APPARATUS FOR ELECTRIC DUST COLLECTOR}

The present invention relates to a charging device for electrostatic precipitation, and more particularly, to a charging device for electrostatic precipitation having a tip holder capable of more stably supporting a discharging tip that generates ions and at the same time reinforcing the rigidity of a frame. .

In general, a method of removing particles includes two processes of charging and dust collection, charging dust and collecting the charged dust with a dust collecting filter.

More specifically, as the dust collection method, there are physical dust collection using a nonwoven fabric, electric dust collection using a dielectric filter, and a method of applying an electrostatic force to the physical dust collecting filter using an electrostatic nonwoven fabric.

The charging method includes diffusion charging, electric field charging, and hybrid charging (diffusion and electric field charging).

Electric field charging applied to hybrid charging is advantageous for trapping large particles, and diffusion charging is advantageous for trapping small particles.

In this regard, Korean Patent Application Laid-Open No. 10-2020-0009889 discloses a configuration related to a structure for fixing conductive microfibers and cables to an installation frame provided inside the body frame and supporting them.

According to the configuration disclosed in the prior literature, an installation opening into which conductive microfibers and cables can be inserted is formed on either side of both sides of the installation frame, and conductive microfibers and cables are inserted in the horizontal direction through the installation opening to conduct The microfibers and cables are press-fitted to the installation frame.

However, in the charging device for electric dust collection disclosed in the prior document, an installation opening is formed by at least partially opening one side of the installation frame, and since the microfiber and the cable are combined in a horizontal direction by an interference fit method, excessive in the bonding process. If force is applied, the possibility of damage to the installation frame is very high. That is, the conductive microfiber is a bar-shaped installation frame in which both ends are fixed, and is fixed at a position spaced apart from both ends by a predetermined distance, and the interference fit coupling force acts in a direction perpendicular to the extension direction of the installation frame. Therefore, even if a fairly small bonding force acts, it becomes a structure in which the installation frame is easily damaged.

In addition, the charging device for electric dust collection disclosed in the related prior art forms an installation opening by at least partially opening one side of the installation frame. Therefore, the rigidity of the installation frame itself is remarkably reduced, and due to this, it is easily broken or damaged even by a fairly small level of external force during the operation of the charging device, and there is a high possibility that the conductive microfibers are separated from the preset position. Accordingly, there is a problem in that the charging efficiency and the discharge efficiency through the conductive microfibers are significantly lowered.

The charging device 100 for electric dust collection functions to charge foreign substances such as dust particles in the air. In addition, the collecting device 200 functions to collect dust particles charged by the electric dust collecting device 100 and remove them from the air.

The charging device 100 for electrostatic precipitation may include a charging module 1000 having a discharging tip 1100 and a conductive plate 1200, which will be described later.

A high voltage is applied to the discharge tip 1100 , and a ground electrode is applied to the conductive plate 1200 . Accordingly, the charging device 100 for electrostatic precipitation may generate ions into the air and form an electric field.

At this time, the conductive plate 1200 may generate an electric field by generating a potential difference with the discharge tip 1100 . A detailed configuration of the charging device 100 for electrostatic precipitation will be described later with reference to FIG. 2 or less.

The collecting device 200 corresponds to a kind of filter performing a function of collecting particles charged by the charging device 100 for electric dust collection, and may be made of various materials.

For example, the collecting device 200 may be configured as a porous fiber filter such as a non-woven fabric. In addition, a conductive material may be applied, coated, or attached to the surface of the collecting device 200 .

Through such a configuration, dust particles in the air passing through the charging device for electric dust collection 100 are combined with ions generated in the charging device for electric dust collection 100 to be charged. In addition, the charged dust particles and the like may be collected by the charging device 100 or the collecting device 200 for electric dust collection.

Meanwhile, the charging device 100 for electric dust collecting according to an embodiment of the present invention may be provided as a separate device separated from the collecting device 200 .

In detail, the charging device 100 and the collecting device 200 for electric dust collection may be produced and distributed through different manufacturing processes and distribution processes. In addition, the charging device 100 and the collecting device 200 for electric dust collection may be coupled to each other by a separate coupling member or the like and mounted on the vehicle air conditioner 1 .

As shown in FIG. 1 , the vehicle air conditioner 1 includes a charging device 100 for electric dust collecting and a dust collecting installation unit 13 in which the collecting device 200 is installed. In more detail, the dust collecting installation part 13 is formed in the suction body 11 adjacent to the suction port 20 .

In particular, the dust collecting installation unit 13 is disposed on the downstream side based on the flow direction of the air introduced into the suction port 20 . This is to allow the air introduced into the suction port 20 to pass through the charging device 100 for electric dust collection before the collection device 200 .

In addition, the vehicle air conditioner 1 is provided with a fan installation unit 12 in which a fan is installed. In detail, the fan installation part 12 is formed in the suction body 11 adjacent to the suction port 20 . In particular, the fan installation unit 12 is disposed on the downstream side with respect to the dust collection installation unit 13 based on the flow direction of the air.

Therefore, in the suction body 11, the suction port 20, the dust collecting installation part 13, and the fan installation part 12 are sequentially arranged in the flow direction of the air. Accordingly, the air introduced into the suction port 20 may flow to the discharge body 15 by sequentially passing through the charging device 100 for electric dust collection, the collection device 200 and the fan.

At this time, the charging device 100 and the collecting device 200 for electric dust collection may be respectively installed in the dust collecting installation unit 13 .

In particular, the replacement cycle of the charging device 100 and the collecting device 200 for electric dust collection may be different from each other. In general, since a larger amount of dust particles are collected in the collecting device 200 , the replacement cycle of the collecting device 200 may be shorter. Accordingly, the user can replace only the collection device 200 without having to replace the charging device 100 for the electric dust collection, so that the user's convenience can be remarkably improved.

In addition, a high density of ions may be generated between the discharge tip 1100 and the conductive plate 1200 .

Since the conductive plate 1200 is provided as a flat plate having a predetermined width in the vertical direction (U-D direction), predetermined dust particles and the like may be collected. However, in order to prevent dust particles from directly adhering to the conductive plate 1200 , the conductive plate 1200 is at least partially covered by the upper frame 1400 to be described later.

The conductive plate 1200 is disposed to surround the discharge tip 1100 . In more detail, the conductive plate 1200 forms a predetermined charging space surrounding the discharge tip 1100 .

As described above, the present invention includes a plurality of discharge tips 1100 and a plurality of tip holders 1500 . The contents described below are almost identically applied to the individual discharge tip 1100 and the tip holder 1500 unless otherwise specified.

8 to 11 show the configuration of the tip holder 1500 according to the first embodiment, and FIG. 12 shows the configuration of the tip holder 1500 according to the second embodiment.

The tip holder 1500 of the charging device 100 for electric dust collection according to an embodiment of the present invention is manufactured separately from the discharge tip 1100 and the high voltage cable 1600, and the discharge tip 1100 and the high voltage cable ( 1600), or may be manufactured by an insert injection method with the discharge tip 1100 and the high voltage cable 1600 placed in a mold.

First, a configuration in which the tip holder 1500 is separately manufactured according to the first embodiment will be described with reference to FIGS. 8 to 11 .

The tip holder 1500 includes a hexahedral body 1510 supporting the discharge tip 1100 and the high voltage cable 1600, and the body 1510 includes a first half 1511 and a second half ( 1512). The first half 1511 and the second half 1512 may be manufactured by injection molding separately from the discharge tip 1100 and the high voltage cable 1600 .

The discharge tip 1100 and the high voltage cable 1600 are at least partially sandwiched between the first half 1511 and the second half 1512 while being pressed by the first half 1511 and the second half 1512. is supported

To this end, the first half 1511 accommodates the high voltage cable 1600 and the discharge tip 1100 , and a shape corresponding to the outer shape of the heat shrinkable tube 1130 and the high voltage cable 1600 supporting the discharge tip 1100 . and a cable seating groove 1511 having a

In addition, the first half 1511 is configured to have a greater thickness than the second half 1512 to be described later to accommodate the high voltage cable 1600 and the discharge tip 1100 .

A coupling groove 1511a for coupling with a second half 1512 to be described later is formed in the first half 1511, and a coupling protrusion 1512a of the second half 1512 is inserted into the coupling groove 1511a.

The second half 1512 is coupled to one side of the first half 1511 in which the cable seating groove 1511 is formed to prevent the high voltage cable 1600 and the discharge tip 1100 from being separated and at the same time, the high voltage cable (1600) and serves to maintain a compression state to the discharge tip (1100).

In order to prevent the discharging tip 1100 from being fixed and separated, a pressing protrusion 1512b for pressing the heat-shrinkable tube 1130 is formed on one side of the second half 1512 facing the first half 1511 .

In addition, a coupling protrusion 1512a for coupling to the first half 1511 is formed on one side of the second half 1512 facing the first half 1511 .

On the other hand, as shown, the upper and lower surfaces of the first half 1511 and the second half 1512 have a pair of upper hook portions 1520 and a pair of lower hook portions 1530 each having substantially the same shape. ) is formed.

At this time, the pair of upper hook portions 1520 and the pair of lower hook portions 1530 are respectively disposed at positions spaced apart from the discharge tip 1100 as far as possible to prevent interference with the discharge tip 1100 , respectively. . Preferably, the upper hook portion 1520 includes a rear upper hook 1521 disposed on the rearmost side of the upper end surface 1540 of the main body 1510 and a front upper disposed on the most front side of the body portion 1510 . may be configured as a hook 1522 .

For the same reason, the lower hook unit 1530 includes a rear lower hook 1531 disposed at the rearmost end of the lower end of the main body 1510 and a front lower hook disposed at the frontmost end of the lower end of the main body 1510 . (1532).

In addition, in order to minimize the interference with the discharge tip 1100, the pair of upper hook part 1520 and the pair of lower hook part 1530 are respectively the above-described first coupling hole 1412b and the second coupling hole 1412b. They are arranged to be deformed in a direction away from each other when fastened to the hole 1422b.

Also, for the same reason, the height h1 at which the discharge tip 1100 protrudes from the top surface 1540 may be set to be greater than the height h2 at which the upper hook part 1520 protrudes from the top surface 1540 .

As described above, the tip holder 1500 may be manufactured by an insert injection method in a state in which the discharge tip 1100 and the high voltage cable 1600 are disposed in a mold.

A configuration in which the tip holder 1500 and the discharge tip 1100 are manufactured by an insert injection method according to the second embodiment will be described with reference to FIG. 12 .

First, as shown in FIG. 12( a ), one end of the carbon brush-type electric discharge brush 1110 and one end of the core wire 1601 of the high voltage cable 1600 are connected through the terminal unit 1120 . One end of the core wire 1601 of the high voltage cable 1600 is exposed to the outside in a state in which the coating 1602 is peeled off.

The terminal portion 1120 covers the contact portion in the circumferential direction while one end of the discharge brush 1110 and one end of the core wire 1601 of the high voltage cable 1600 are in contact with each other, and serves to press the contact portion. .

The discharge brush 1110 of the discharge tip 1100 is electrically connectable to the cable 1600 through the terminal unit 1120 .

Next, as shown in FIG. 12( b ), the heat-shrinkable tube 1130 is introduced so that the heat-shrinkable tube 1130 surrounds at least the contact portion between the discharge brush 1110 and the terminal part 1120 . In this case, the heat-shrinkable tube 1130 is extendable to the contact portion between the cable 1600 and the terminal unit 1120 .

As will be described later, in order to prevent damage to the discharge brush 1110 by the injection pressure, the heat-shrinkable tube 1130 passes through the contact portion between the discharge brush 1110 and the terminal unit 1120 and cuts a part of the lower end of the discharge brush 1110. It is desirable to extend to cover it.

Next, when the arrangement of the heat-shrinkable tube 1130 is completed, the heat-shrinkable tube 1130 is heated and contracted. The primary airtight state of the contact portion between the discharge brush 1110 and the terminal unit 1120 is completed by the shrinkage of the heat shrinkable tube 1130 .

Next, as shown in FIG. 12( c ), the cable 1600 is bent at a predetermined angle to set the orientation angle of the discharge brush 1110 .

12( c ) shows an embodiment in which the bending part 1610 is bent so that the discharge brush 1110 is almost perpendicular to the horizontal plane. The angle can be adjusted.

In particular, it is also possible to adjust the angle of the bending part 1610 so that the rest of the five discharge tips 1100 except for the discharge brush 1110 disposed in the center face inward.

When the setting of the directing angle of the discharge tip 1100 with respect to the discharge brush 1110 is completed, the discharge brush 1110, the terminal part 1120, and moving the cable 1600 into the cavity of the mold.

At this time, in order to minimize the effect of the injection pressure, it is preferable that the discharge brush 1110 is not directly exposed to the injection pressure, and the heat-shrinkable tube 1130 is at least partially disposed outside the cavity. That is, when insert injection is completed, a part of the heat shrinkable tube 1130 protrudes from the top surface 1540 of the tip holder 1500 and is exposed to the outside, and the remaining part may be embedded in the inside of the tip holder 1500. .

For this purpose, as shown in FIG. 12(d), the contact portion between the discharge brush 1110 and the terminal unit 1120 is disposed outside the cavity of the mold, and the contact portion between the cable 1600 and the terminal unit 1120 is at least It may be disposed partially inside the cavity of the mold.

When disposition of the mold into the cavity is completed in this way, insert injection proceeds and the tip holder 1500 is formed.

When the injection is completed, as shown, the contact portion between the cable 1600 and the terminal unit 1120 is at least partially embedded in the tip holder 1500 . This completes the secondary airtight state for these contact parts.

Therefore, by manufacturing through insert injection, the processing deviation of the assembly consisting of the individual discharge brush 1110, the cable 1600, and the tip holder 1500 can be significantly reduced compared to the prior art, and the discharge tip 1100 and the cable ( 1600), the penetration of moisture into the contact point can be fundamentally blocked.

In addition, since the contact point between the discharge brush 1110 and the cable 1600 is firmly supported through the tip holder 1500 formed by insert injection, between the discharge tip 1100 and the cable 1600 due to vibration and shock, etc. It is possible to significantly reduce the possibility of occurrence of a disconnection phenomenon.

<Connection structure of high voltage cable>

In this case, the distances from the third discharging tip 1130 disposed at the center to the other discharging tips 1110 , 1120 , 1140 , and 1150 may be set to be the same, respectively. Accordingly, ions may be evenly discharged into the air from each of the discharge tips 1110 , 1120 , 1130 , 1140 , and 1150 , and the charging efficiency for dust particles may be maximized.

On the other hand, as shown, the first to fifth cables 1621, 1622, 1623, 1624, 1625 for supplying voltage to the first to fifth discharge tips 1110, 1120, 1130, 1140, and 1150, respectively. ) is connected, and as described above, the contact area between the individual discharge tips 1110, 1120, 1130, 1140, 1150 and the individual cables 1621, 1622, 1623, 1624, 1625 is the individual tip holder 1510, 1520, 1530, 1540, 1550) are internally protected.

In this case, the first to fifth cables 1621 , 1622 , 1623 , 1624 , and 1625 may be individually configured to be electrically connected to the above-described high voltage supply unit 2200 . However, when configured to be individually connected as described above, a space for supporting and reporting the individual cables 1621 , 1622 , 1623 , 1624 , 1625 must be additionally secured, and the connection terminals are individually installed in the high voltage supply unit 2200 . Problems that should be encountered arise. That is, the number or length of required cables is increased, and the size of the frame 1400 supporting and protecting the cables 1621 , 1622 , 1623 , 1624 , and 1625 is inevitably increased.

As a means for solving such a problem, the charging device 100 for electric dust collection according to the present invention includes a cable holder 1800 for simplifying the connection structure of the high voltage cables 1621 , 1622 , 1623 , 1624 , 1625 . do.

More specifically, the other end of the main cable 1610, one end of which is electrically connected to the high voltage supply unit 2200, penetrates the left side 1804 of the cable holder 1800 to extend into the cable holder 1800. have. As illustrated by way of example, the other end of the main cable 1610 may extend through the upper side of the left side 1804 of the cable holder 1800 . In this way, since only a single main cable 1610 is electrically connected to the high voltage supply unit 2200 , the configuration of the connection unit of the high voltage supply unit 2200 can be simplified.

Meanwhile, the other end of the main cable 1610 extending into the cable holder 1800 may be branched into first to fifth cables 1621 , 1622 , 1623 , 1624 , and 1625 .
