It is preferable that two through holes 1222 formed in the cover coupled to the upper end of the suction part 1221 are formed.

The reason that the upper end of the suction part 1221 is formed narrow and the lower end is formed wide is to reduce wind loss of air passing through the filter 1216 by increasing the penetration area of the lower end to which the filter 1216 is coupled.

The coupling recess 1224 has a cylindrical shape through which the top and bottom are penetrated, and the coupling protrusion 1213 of the filter unit 1210 is interpolated, and the inner diameter of the coupling recess 1224 is preferably formed in a conical shape that becomes narrower toward the top. Do.

A suction fan 1230 for inhaling and exhausting air by a motor is coupled to an upper portion of the suction unit 1221 of the suction and discharge unit 1220.

That is, the suction port 1231 of the suction fan 1230 is connected and coupled to the through hole 1222 formed at the upper end of the suction part 1221, and the suction fan is at the upper end of the discharge part 1225 of the suction and discharge part 1220. The outlet 1232 of the 1230) is connected and coupled.

It is preferable that the motor of the suction fan 1230 is a sirocco motor.

Edge cover type LED lights are LED lights installed indoors, and are characterized by the thin thickness of the lighting fixtures, and the motor itself is slim for efficient operation of the fine dust air purification system while maintaining the characteristic structure of such edge cover type LED lights. It is more effective to configure it with a sirocco motor.

A filter part 1210 is interpolated to a lower end of the suction and discharge part 1220.

The filter unit 1210 is inserted into the suction unit 1221 of the suction and discharge unit 1220, and the filter body 1211 in the shape of a polygonal cylinder with open upper and lower portions and a filter grill 1215 formed at the lower end of the filter body And a coupling protrusion 1213 formed outside the filter body 1211 and a purified air discharge part 1219 formed on the left/right sides of the filter body 1211.

The filter body 1211 is interpolated and coupled to the suction part 1221 of the suction and discharge part 1220 from the bottom to the top.

The coupling protrusion 1213 is interpolated and coupled to the coupling recess 1224 of the suction and discharge portion 1220 from below.

Therefore, it is preferable that a plurality of the coupling protrusions 1213 are also formed at positions corresponding to the coupling recesses 1224, and it is even more preferable to form four.

The coupling protrusion 1213 has a cylindrical shape, and the outer diameter of the coupling protrusion 1213 is preferably formed in a conical shape corresponding to the inner diameter of the coupling recess 1224.

The tangy spring 1214 has elasticity that separates between the coupling recesses 1224 and the coupling protrusions 1213 interpolated to the coupling recesses 1224.

The purified air discharge part 1219 is a "b" shaped through hole, and the upper end of the purified air discharge part 1219 is coupled to the lower end of the discharge part 1225.

Accordingly, the purified air from which the fine dust discharged to the purified air discharge unit 1219 is discharged is not discharged directly below it but is discharged in a horizontal direction, so that it does not directly touch a person.

The filter 1216 is mounted on the lower end of the filter body 1211 having a polygonal cylindrical shape.

Preferably, a filter grill 1215 is formed at the bottom of the polygonal cylindrical filter body 1211, and the filter 1216 is mounted on the filter grill 1214, so that the filter 1216 can be mounted stably and easily. .

A partition wall 1212 is formed in the center of the polygonal cylindrical filter body 1211.

Due to the partition wall 1212, the suction part 1221 is divided into two spaces symmetrically to each other, and thus, two suction fans 1230 respectively connected and coupled to the two through holes 1222 formed at the upper end of the suction part 1221 Each air intake passage by means is formed.

A fine dust sensor 1217 is formed on one side of the polygonal cylindrical filter body 1211.

A band-shaped fine dust status indicator 1218 is formed at the edge of the section where the fine dust sensor 1217 is located.

The fine dust status indicator 1218 is preferably formed of an LED lamp.

Since the fine dust sensor 1217 senses fine dust in the air sucked by the suction fan provided in the sensor itself, it is possible to sense a concentration of fine dust that is closer to an average value than sensing in a congested place.

Since the fine dust status indicator 1218 is formed in a band shape at the edge of the section where the fine dust sensor 1217 is located, it stands out to people's eyes.

The fine dust status indicator 1218 displays in colors such as green (good) yellow (boundary) red (poor) according to the fine dust status, so that people in the space can visually recognize the state of the air and respond with mobility. There is this.

The traction unit 1240 is a means for elevating the filter unit 1210 in the edge cover type LED lamp frame 1010.

Looking specifically at the configuration of the traction unit 1240, the traction motor 1241 is fixed to the upper portion of the suction and discharge unit 1220.

It is more effective that the pulley 1243 rotates by receiving the rotational force of the traction motor 1241, and preferably, the rotational force is transmitted from the traction motor 1241 to the pulley 1243 through the reducer 1242.

It is preferable that a plurality of winding portions 1244 are formed on the pulley 1243, and it is even more preferable that four winding portions 1244 are formed.

Therefore, it is preferable that a plurality of tow lines 1245 to be wound on the winding part 1244 are also used, and it is even more preferable to use four.

An upper portion of the suction/discharge part 1220 is provided with a tension adjusting means 1246 for supporting the tow line 1245 and adjusting the tensile force.

The tension control means 1246 includes a control plate 1247 fixedly installed near the coupling recess 1224 of the suction/discharge part 1220, a support roller 1248 installed on both sides of an upper end of the control plate 1247, and the support roller ( 1248) It consists of a variable roller 1249 that can be variable vertically from the center.

The support/variable roller has a concave groove in which a tow line 1245 is seated in an outer diameter.

The tension adjusting means 1246 is possible by adjusting the position of the variable roller 1249 up and down in order to maintain the horizontal level of the filter unit 1210 attached to the four towing lines 1245 when using the four towing lines 1245. . That is, it is possible to precisely adjust the horizontal of the filter unit by adjusting the distance of the tow line path of the tension control means.

That is, the tension control means 1246 includes a control plate 1247 fixedly installed near the coupling recess 1224 of the suction/discharge part 1220, support rollers 1248 installed on both sides of the upper end of the control plate 1247, and the The variable roller 1249, which is positioned vertically in the slit formed in the vertical direction in the center between the support rollers 1248, is fixed at a specific position, so that the distance of each tow line path of the tension adjusting means 1246 is adjusted so that the filter unit ( 1210) can be precisely maintained.

The support/variable rollers 1248 and 1249 are provided with guides 1250 for preventing the separation of the rollers of the pull line 1245 passing through each roller.

The traction line 1245 wound around each of the winding portions 1244 is the support roller 1248 of the tension control means 1246, the variable roller 1249, the support roller 1248, and the coupling recess 1224 of the suction and discharge portion 1220. It is fixed to the coupling protrusion 1213 of the filter unit 1210 through the sequential passage.

Looking at the lifting operation relationship of the filter unit 1210 by the traction unit 1240,

When the motor rotates forward due to the operation of the traction motor 1241, the pulley rotates forward and the traction line 1245 wound around each winding unit 1244 of the pulley is wound, so that the filter unit 1210 coupled to the traction line 1245 rises. The filter unit 1210 is normally coupled to the air purification system 1200 by being inserted into the suction and discharge unit 1220.

At this time, it is preferable to install a lift limit switch (not shown) that stops the rotation of the traction motor 1241 when the filter unit 1210 is coupled, and the lift limit switch includes the filter unit 1210 in the suction and discharge unit 1220 When it is inserted to the set position of ), it is mechanically detected and operated.

When the traction motor 1241 continues to rotate forward in a state in which the filter unit 1210 is normally coupled to the suction/discharge unit 1220 and the traction line 1245 can no longer be wound around the winding unit 1244, the lift limit switch This is to prevent burnout caused by overloading the traction motor 1241.

When the filter 1216 of the filter unit 1210 is replaced, if the traction motor 1241 is rotated in the reverse direction, the pulley rotates in the reverse direction, and the traction line 1245 that was wound on each winding part 1244 of the pulley is released. ), the filter unit 1210 is lowered by the self-weight of the filter unit 1210 attached to the filter unit 1210, and when the filter unit 1210 descends at the set position, the filter 1216 mounted on the filter unit 1210 is conveniently replaced. can do.

At this time, it is preferable to install a descending limit switch (not shown) to stop the reverse rotation of the traction motor 1241 when the filter unit 1210 descends to the set position.

This is because if the reverse rotation of the traction motor 1241 continues to reverse even after the traction line 1245 is completely unwound from the winding unit 1244, the traction line 1245 is rewinded to the winding unit 1244 and the filter unit 1210 rises again. To prevent it from doing.

The lowering limit switch is operated when the angle of the tow line 1245 is out of the set angle by sensing the angle of the tow line 1245 wound around the winding portion 1244,

When the traction motor 1241 is rotated after replacing the filter 1216, the filter unit 1210 rises by the traction force of the traction line 1245 wound around the winding unit 1244 and is interpolated to the suction and discharge unit 1220.

In the traction part 1240, the winding part 1244 and the traction line 1245 are set to four in order to maintain the horizontal level of the filter part 1210 that is elevating.

If the tow line 1245 is used as one, the structure is simple, but when the filter unit 1210 is raised or lowered, the filter unit 1210 is not leveled and tilted or rotated, making the user uneasy as well as the filter unit 1210 descending. That is, when the filter unit 1210 is separated from the suction/discharge unit 1220, if the filter unit 1210 is unbalanced, it may not be easily separated. That is, the coupling protrusion 1213 of the filter part 1210 may not be easily separated from the coupling recess 1224 of the suction and discharge part 1220.

In addition, in order to allow the filter unit 1210 to be safely separated from the suction and discharge unit 1220 when the filter unit 1210 descends, the coupling protrusion 1213 of the filter unit 1210 and the suction/discharge unit 1220 are coupled together ( It is preferable that the tangy spring 1214 is interposed between 1224).

That is, the tangy spring 1214 is interposed between the engagement protrusion 1213 and the engagement recess 1224 by extrapolating the tangy spring 1214 to the engagement protrusion 1212 of the filter unit 1210.

When the tangy spring 1214 is interposed between the coupling protrusion 1213 and the coupling recess 1224, the filter portion 1210 is safely separated from the suction and discharge portion 1220 by the elastic force of the tangy spring 1214.

It is preferable that the operation of the traction unit 1240 is remotely controlled by a remote control.

The above has been described with reference to a preferred embodiment of the present invention, and is not limited to the above embodiment, and through the above embodiment, those of ordinary skill in the art to which the present invention belongs do not depart from the gist of the present invention. This can be done with various changes in.
