Abstract

An electrification apparatus is used for electric dust collection in an air conditioner for a vehicle. The electrification apparatus includes a frame, a conductive microfiber, and a conductive plate. The frame includes a main body frame in which the conductive plate is installed and an installation frame that defines a fixing groove in which the conductive microfiber is installed. The electrification apparatus further includes a rubber coupled with the conductive microfiber and inserted into the fixing groove.

Claims (34)

1. An electrification apparatus for electric dust collection, comprising:

a frame;

a conductive microfiber disposed in the frame and configured to generate ions in air; and

conductive plates disposed in the frame and configured to generate a potential difference with the conductive microfiber;

an electric wire connected to the conductive microfiber and configured to apply a high voltage to the conductive microfiber,

wherein the frame comprises:

a main body frame that accommodates the conductive plates, and

an installation frame that defines a fixing groove configured to receive the conductive microfiber,

wherein the electrification apparatus further comprises a rubber structure coupled with the conductive microfiber and configured to insert into the fixing groove, the rubber structure having a cylindrical shape and defining an inner opening that surrounds an outside of the conductive microfiber or the electric wire,

wherein the installation frame comprises:

a first installation surface that defines the fixing groove,

a second installation surface that extends downward from a first side of the first installation surface, the second installation surface defining an installation hole configured to receive the rubber structure and the electric wire, and

a third installation surface that extends downward from a second side of the first installation surface, and

wherein the first installation surface, the second installation surface, and the third installation surface define an installation space that accommodates and covers the electric wire.

2. The electrification apparatus according to claim 1 , wherein the electric wire extends from the conductive microfiber along the installation frame.

3. The electrification apparatus according to claim 2 , wherein at least one end of the installation frame is connected to the main body frame, and

wherein the electric wire extends to the main body frame along the installation frame and further extends along the main body frame, the electric wire extending to an outer power source through the main body frame.

4. The electrification apparatus according to claim 1 , wherein the rubber structure is coupled between the conductive microfiber and the electric wire.

5. The electrification apparatus according to claim 1 , wherein the installation space has a bottom opening that is defined by the second installation surface and the third installation surface.

6. The electrification apparatus according to claim 1 , wherein the fixing groove, the installation hole, and the installation space are in communication with one another.

7. The electrification apparatus according to claim 1 , wherein the conductive microfiber protrudes above the first installation surface, and the electric wire is located below the first installation surface, and

wherein at least a portion of the rubber structure protrudes above the first installation surface.

8. The electrification apparatus according to claim 1 , wherein the installation frame further comprises a rubber support protrusion that protrudes upward from the first installation surface and that surrounds at least a portion of the rubber structure.

9. The electrification apparatus according to claim 8 , wherein the rubber support protrusion has a ring shape, and the fixing groove extends through the rubber support protrusion.

10. The electrification apparatus according to claim 1 , wherein an outer circumferential surface of the rubber structure is in contact with an inner circumferential surface of the fixing groove.

11. The electrification apparatus according to claim 10 , wherein the rubber structure comprises a protrusion that protrudes radially outward from the outer circumferential surface of the rubber structure and that is disposed below the fixing groove, the protrusion having a ring shape extending along the outer circumferential surface of the rubber structure.

12. The electrification apparatus according to claim 11 , wherein the installation frame further comprises a rubber support protrusion that protrudes upward from an upper surface of the installation frame, that surrounds at least a portion of the rubber structure, and that supports the protrusion of the rubber structure.

13. The electrification apparatus according to claim 12 , wherein the rubber support protrusion has a side opening that is connected to the fixing groove and that is configured to receive the rubber structure.

14. The electrification apparatus according to claim 10 , wherein the rubber structure comprises:

a first protrusion that protrudes radially outward from the outer circumferential surface of the rubber structure, that is disposed below the fixing groove, and that extends along the outer circumferential surface of the rubber structure; and

a second protrusion that protrudes radially outward from the outer circumferential surface of the rubber structure, that is disposed above the fixing groove, and that extends along the outer circumferential surface of the rubber structure.

15. The electrification apparatus according to claim 14 , wherein the first protrusion of the rubber structure surrounds the electric wire, and the second protrusion of the rubber structure surrounds the conductive microfiber.

16. The electrification apparatus according to claim 14 , wherein the installation frame comprises a rubber support protrusion that protrudes upward from an upper surface of the installation frame, that surrounds at least a portion of the rubber structure, and that supports the second protrusion of the rubber structure.

17. The electrification apparatus according to claim 1 , wherein the installation hole extends to the fixing groove.
