Optical disk drive comprising dust removing apparatus
View Patent ↗An optical disk drive, which includes a main frame, an upper case coupled to an upper portion of the main frame, a tray slidably installed on the main frame, having a door, and adapted to carry a disk, and a front panel coupled to a front end portion of the main frame and having an aperture through which the tray passes, including an air discharging passage between the main frame and the front panel to discharge air and dust introduced into the optical disk drive through a gap between the door and the front panel to an outside of the optical disk drive.
1. An optical disk drive, which includes a main frame, an upper case coupled to an upper portion of the main frame, a tray slidably installed on the main frame, having a door, and adapted to carry a disk, and a front panel coupled to a front end portion of the main frame and having an aperture through which the tray passes, the optical disk drive comprising:
an air discharging passage between the main frame and the front panel to discharge air and dust introduced into the optical disk drive through a gap between the door and the front panel to an outside of the optical disk; and
a plurality of projections arranged on at least a top surface of the tray to remove dust contained in air flowing inside the optical disk drive.
2. The optical disk drive of claim 1 , wherein the air discharging passage has an inlet which is opened toward a rear surface of the door to communicate with the gap, and an outlet, which is opened toward a bottom of the optical disk drive to allow the air discharging passage to communicate with the outside of the optical disk drive.
3. The optical disk drive of claim 2 , wherein most of air introduced into the disk drive through the gap is discharged to the outside of the disk drive through the air discharging passage.
4. The optical disk drive of claim 1 further comprising an air guide disposed on at least one of a top surface of the tray, a bottom surface of the tray, and a bottom surface of the upper case to guide air flowing due to the rotation of the disk toward the projections.
5. The optical disk drive of claim 4 , wherein the air guide has a bar shape.
6. The optical disk drive of claim 4 , wherein the air guide extends outward by a height as great as possible without causing interference with other elements when the tray is move.
7. The optical disk drive of claim 4 , wherein the air guide is integrally formed with the tray.
8. An optical disk drive, which includes a main frame, an upper case coupled to an upper portion of the main frame, and a tray slidably installed on the main frame to carry a disk, the optical disk drive comprising:
a plurality of projections arranged on at least a top surface of the tray to remove dust contained in air flowing inside the optical disk drive.
9. The optical disk drive of claim 8 , wherein the projections are arranged on a top surface of a rear end portion of the tray.
10. The optical disk drive of claim 8 , wherein the projections are also arranged a bottom surface of a rear end portion of the tray.
11. The optical drive of claim 10 , wherein the projections are formed on a top surface of the front end portion of the tray.
12. The optical disk drive of claim 8 , wherein the projections have a square-pillar shape.
13. The optical drive of claim 8 , wherein the projections have a cylindrical shape.
14. The optical disk of claim 8 , wherein the projections extend from tray by a height as great as possible without causing interference with other elements when the tray is moved.
15. The optical disk of claim 8 , wherein the projections are arranged irregularly.
16. The optical disk drive of claim 8 , wherein the projections are integrally formed with the tray.
17. The optical disk drive of claim 8 , further comprising an air guide disposed on at least one of top surface of the tray, a bottom surface of the tray, and a bottom surface of the upper case to guide air flowing due to the rotation of the disk toward the projections.
18. The optical disk drive of claim 17 , wherein the air guide is disposed on the top surface of the tray.
19. The optical disk drive of claim 18 , wherein the air guide is integrally formed with the tray.
20. The optical disk drive of claim 17 , wherein the air guide protrudes from the bottom surface of the upper case by a specified height toward the tray.
21. The optical disk drive of claim 20 , wherein the air guide is integrally formed with the upper case.
22. The optical disk drive of claim 17 , wherein the air guide is made of a porous filtering material.
23. An optical disk drive comprising:
a frame;
an upper case coupled to an upper portion of the frame;
a tray slidably installed on the frame, having a door, and adapted to carry a disk;
a front panel coupled to a front end portion of the frame and having an aperture through which the tray passes;
an air discharging passage between the frame and the front panel to discharge to an outside of the optical disk drive air and dust introduced into the optical disk drive through a gap between the door and the front panel; and
a plurality of projections arranged on at least a top surface of the tray to remove dust contained in air flowing inside the optical disk drive.
