Abstract

An electrification apparatus for dust collection includes an electrification module configured to generate an ion emitted to air and comprising: at least one discharge tip configured to emit the ion in a direction opposite to a flow direction of the air, at least one tip holder supporting the discharge tip, a conductive plate generating a potential difference with the discharge tip, and a frame defining an appearance of the electrification module and supporting the tip holder and the conductive plate. The frame comprises an upper frame disposed at an upper side of the conductive plate and a lower frame disposed at a lower side of the conductive plate, the tip holder is disposed between the upper frame and the lower frame, and an upper surface of the tip holder is coupled to the upper frame and a lower surface of the tip holder is coupled to the lower frame.

First claim

What is claimed is:

1. An electrification apparatus for dust collection, comprising:
an electrification module configured to generate an ion that is emitted to air, wherein the electrification module comprises:
at least one discharge tip configured to emit the ion in a direction opposite to a flow direction of the air;
at least one tip holder supporting the discharge tip;
a conductive plate configured to generate a potential difference with the discharge tip; and
a frame that defines an appearance of the electrification module and that supports the tip holder and the conductive plate,

wherein the frame comprises an upper frame disposed at an upper side of the conductive plate and a lower frame disposed at a lower side of the conductive plate,
wherein the tip holder is disposed between the upper frame and the lower frame,
wherein an upper surface of the tip holder is coupled to the upper frame and a lower surface of the tip holder is coupled to the lower frame, and
wherein the upper surface of the tip holder is detachably coupled to the upper frame, and the lower surface of the tip holder is detachably coupled to the lower frame.

2. The electrification apparatus of claim 1 , wherein the tip holder comprises:
a hexahedral main body having an upper surface coupled to the upper frame and a lower surface coupled to the lower frame;
a pair of upper hooks that protrudes upward from the upper surface of the hexahedral main body and that is coupled to the upper frame; and
a pair of lower hooks that protrudes downward from the lower surface of the hexahedral main body and that is coupled to the lower frame.

3. The electrification apparatus of claim 2 ,
wherein the pair of upper hooks comprises:
a front upper hook disposed at a front end of the upper surface of the hexahedral main body; and
a rear upper hook disposed at a rear end of the upper surface of the hexahedral main body, and

wherein the discharge tip is disposed between the front upper hook and the rear upper hook and protrudes upward from the upper surface of the hexahedral main body.

4. The electrification apparatus of claim 3 , wherein a height of the discharge tip from the upper surface of the hexahedral main body is taller than a height of each of the front upper hook and the rear upper hook from the upper surface of the hexahedral main body.

5. The electrification apparatus of claim 3 , wherein the front upper hook and the rear upper hook are configured to be angled, based on the front upper hook and the rear upper hook being coupled to the upper frame, in a direction away from each other.

6. The electrification apparatus of claim 3 , wherein the pair of lower hooks comprises:
a front lower hook disposed at a front end of the lower surface of the hexahedral main body; and
a rear lower hook disposed at a rear end of the lower surface of the hexahedral main body.

7. The electrification apparatus of claim 6 , wherein the front lower hook and the rear lower hook are configured to be angled, based on the front lower hook and the rear lower hook being coupled to the lower frame, in a direction away from each other.

8. The electrification apparatus of claim 6 ,
wherein the upper frame comprises a pair of first coupling holes through which the front upper hook and the rear upper hook pass and defines an opening that is disposed between the pair of first coupling holes and through which (i) the discharge tip passes and (ii) a part of the upper surface of the hexahedral main body is exposed to outside of the frame.

9. The electrification apparatus of claim 8 , wherein the lower frame comprises a pair of second coupling holes through which the front lower hook and the rear lower hook pass.

10. The electrification apparatus of claim 2 , wherein the electrification module further comprises a high voltage cable that extends inward through the hexahedral main body and that is electrically connected to the discharge tip inside the hexahedral main body.

11. The electrification apparatus of claim 10 ,
wherein the electrification module further comprises a tube that surrounds a contact point at which the discharge tip and the high voltage cable are electrically connected, and
wherein a part of the tube protrudes from the upper surface of the tip holder.

12. The electrification apparatus of claim 11 , wherein the tube is a heat shrinkable tube.

13. The electrification apparatus of claim 10 ,
wherein the hexahedral main body comprises a first body and a second body that are manufactured separately, and
wherein portions of the discharge tip and the high voltage cable are (i) disposed between the first body and the second body and (ii) pressed by the first body and the second body.

14. The electrification apparatus of claim 13 , wherein a first surface of the first body facing the second body defines a seating groove that has a shape corresponding to an outer shape of the discharge tip and the high voltage cable.

15. The electrification apparatus of claim 10 , wherein the discharge tip and the high voltage cable are coupled to the hexahedral main body by insert injection molding.

16. The electrification apparatus of claim 10 ,
wherein the electrification module further comprises a high voltage supplier configured to generate a voltage to supply the voltage to the discharge tip, and
wherein the high voltage cable comprises a main cable having a first end electrically connected to the high voltage supplier.

17. The electrification apparatus of claim 16 ,
wherein the at least one discharge tip comprises a first discharge tip and a second discharge tip that are spaced apart from each other,
wherein the high voltage cable further comprises a first cable electrically connected to the first discharge tip and a second cable electrically connected to the second discharge tip, and
wherein each of the first cable and the second cable is branched from a second end of the main cable.

18. The electrification apparatus of claim 17 , wherein the electrification module further comprises a cable holder configured to accommodate a branch portion at which the main cable is branched into the first cable and the second cable.

19. The electrification apparatus of claim 18 , further comprising a cover module disposed at a front side of the electrification module,
wherein the cover module comprises the high voltage supplier.
