Abstract

The control panel of a laundry processing machine according to the present invention making the light emitted from plural LEDs direct only to transparent protrusions by protrudingly forming the ribs in between plural transparent protrusions. Therefore user recognition effect may be increased.

Claims

1. The control panel of a laundry processing machine comprising:

a control substrate with plural LEDs;

a transparent window formed plural transparent protrusions corresponded to the plural LEDs; and

a light spread preventing means which is placed in between the plural transparent protrusions and one of the light emitted from the plural LEDs is only directed to the corresponding transparent protrusions.

2. The control panel of a laundry processing machine of claim 1, wherein the light spread preventing means is the ribs formed protrudingly in between the plural transparent protrusions.

3. The control panel of a laundry processing machine of claim 1, wherein the control panel further comprises display cover formed to be inserted by the plural transparent protrusions.

4. The control panel of a laundry processing machine of claim 3, wherein the light spread preventing means is the ribs forming protrudingly in between the plural transparent protrusions at the surface of the display covers.

5. The control panel of a laundry processing machine of claim 4, wherein the control panel comprises the rotary switch placed on the control substrate and the plural LEDs mounted to surround the rotary switch according to circular direction at predetermined intervals.

6. The control panel of a laundry processing machine of claim 4, wherein the control panel further comprises the transparent window including a platebody which is formed to follow the arc shape of the rotary switch, and the plural transparent protrusions are in at least one side of the interior or exterior of the platebody, which is formed to protrude in back and forth directions.

7. The control panel of a laundry processing machine of claim 6, wherein the transparent window has the rib insert holes to insert the ribs in between the plural transparent protrusions.

8. The control panel of a laundry processing machine of claim 6, wherein the control panel is further including the LED supporters which supports the plural LEDs mounted in a control substrate.

9. The control panel of a laundry processing machine of claim 4, wherein the light spread preventing means is the ribs protruding in between the plural transparent protrusions from the LED supporters.

10. The control panel of a laundry processing machine of claim 9, wherein the transparent window has the rib insert holes to insert the ribs in between the plural transparent protrusions.

11. The control panel of a laundry processing machine of claim 1, wherein the control panel is further including the LED supporters which support the plural LEDs mounted in the control substrate.

12. The control panel of a laundry processing machine of claim 11, wherein the light spread preventing means is the ribs protruding in between the plural transparent protrusions from the LED supporters.

13. The control panel of a laundry processing machine of claim 11, wherein the LED supporter protrude to form the plural walls to surround each individual LED.

14. The control panel of a laundry processing machine of claim 13, wherein the walls are formed to extend in between the transparent protrusions.

15. The control panel of a laundry processing machine of claim 12, wherein the windows has the rib insert holes to insert the ribs in between the plural transparent protrusions.

16. The control panel of a laundry processing machine of claim 1, wherein the control panel is further comprised of the control panel which is to cover control substrate to form the exterior.

17. The control panel of a laundry processing machine comprising:

a control substrate with plural LEDs;

a transparent window with plural transparent protrusions that counteracts the plural LEDs;

a display cover in which the plural light display holes are formed to be corresponded to each plural LEDs; and

a light spread preventing means which is placed in between the plural light display hole and one of the light emitted from plural LEDs is only directed to the light display hole.

18. The control panel of a laundry processing machine of claim 17, wherein the light spread preventing means is the ribs protruding toward the transparent windows on the back side of the display cover.

19. The control panel of a laundry processing machine of claim 18, wherein the rib insert hole is formed to insert the rib on the transparent window.

20. The control panel of a laundry processing machine of claim 17, wherein the control panel is further comprised of the control panel which is to cover control substrate to form the exterior.
