Abstract

A home appliance, e.g. a refrigerator, includes a cabinet forming a space and a door for opening and closing the space, the door including a door body with an insulator filled therein, and a panel assembly mounted in front of the door body, wherein the panel assembly includes a lighting device configured to emit light, a panel forming a front surface of the door and configured to transmit light therethrough, a light guide plate disposed behind the panel and configured to guide light emitted from the lighting device to the panel, and a member disposed between the panel and the light guide plate, including the panel and the light guide plate mounted thereon, and configured to transmit light of the light guide plate through an entire part of the panel.

First claim

The invention claimed is:

1. A refrigerator comprising:
a cabinet that defines a storage space; and
a door configured to open and close at least a portion of the storage space, the door comprising a door body that accommodates an insulator and a panel assembly disposed on the door body,
wherein the panel assembly comprises:
a lighting device configured to emit light,
a panel that defines a front surface of the door and is configured to transmit the light emitted from the lighting device,
a light guide plate disposed rearward relative to the panel and configured to guide the light emitted from the lighting device toward the panel, and
a member that is made of a material configured to transmit the light and that is disposed between the panel and the light guide plate, the member partitioning a space between a rear surface of the panel and a front surface of the light guide plate and being configured to transmit the light from the light guide plate to the panel.

2. The refrigerator of claim 1 , wherein the member includes:
a front part that faces the panel and partitions the space between the rear surface of the panel and the front surface of the light guide plate; and
side parts that extend from lateral sides of the front part toward the door body to thereby define an accommodation space that receives the light guide plate.

3. The refrigerator of claim 2 , wherein each of the side parts includes:
a first extension that extends from the front part toward the door body; and
a second extension that extends from the first extension in a direction parallel to the front part, and
wherein the accommodation space comprises a first space that is defined by the first extension and the second extension and receives the light guide plate.

4. The refrigerator of claim 3 , wherein the first space has an upper opening and a lower opening that are spaced apart from each other in a vertical direction to thereby allow the light guide plate to be inserted into the first space and removed from the first space in the vertical direction through the upper opening or the lower opening, and
wherein a shape of a first horizontal cross-section of the member defined at a first point of the member is identical to a shape of a second horizontal cross-section of the member defined at a second point of the member, the second point being spaced apart from the first point in the vertical direction.

5. The refrigerator of claim 3 , wherein a distance between the front part and the second extension corresponds to a thickness of the light guide plate.

6. The refrigerator of claim 3 , wherein the front part is in contact with the front surface of the light guide plate,
wherein the second extension is in contact with a rear surface of the light guide plate, and
wherein the first extension is in contact with a side surface of the light guide plate.

7. The refrigerator according to claim 3 , wherein the panel assembly further comprises:
an upper bracket that defines an upper surface of the panel assembly and is disposed at an upper end of the member; and
a lower bracket that defines a lower surface of the panel assembly and is disposed at a lower end of the member.

8. The refrigerator of claim 7 , wherein each of the side parts further comprises a third extension that is spaced apart from the second extension and protrudes from the first extension in the direction parallel to the front part, and
wherein the accommodation space further comprises a second space that is defined between the second extension and the third extension and receives the upper bracket and the lower bracket.

9. The refrigerator of claim 8 , wherein the third extension protrudes farther toward a center of the member than the second extension.

10. The refrigerator of claim 7 , wherein the lighting device is disposed at at least one of the upper bracket or the lower bracket.

11. The refrigerator according to claim 7 , wherein the member defines:
an upper step portion that receives the upper bracket at the upper end of the member; and
a lower step portion that receives the lower bracket at the lower end of the member.

12. The refrigerator according to claim 2 , wherein the panel assembly further comprises a back cover that is disposed at rear surfaces of the side parts and defines a rear surface of the panel assembly.

13. The refrigerator according to claim 12 , wherein the panel assembly further comprises:
an upper bracket that defines an upper surface of the panel assembly and is disposed at an upper end of the member; and
a lower bracket that defines a lower surface of the panel assembly and is disposed at a lower end of the member.

14. The refrigerator according to claim 13 , wherein the rear surfaces of the side parts are flush with a rear surface of the upper bracket, and
wherein the back cover is in contact with the rear surfaces of the side parts and the rear surface of the upper bracket.

15. The refrigerator according to claim 1 , wherein the rear surface of the panel faces a front surface of the member, and
wherein a surface area of the rear surface of the panel is equal to a surface area of the front surface of the member.

16. The refrigerator according to claim 1 , wherein a width of the panel in a first direction is equal to a width of the member in the first direction, and
wherein a height of the panel in a second direction orthogonal to the first direction is equal to a height of the member in the second direction.

17. The refrigerator according to claim 1 , wherein the member is configured to diffuse the light based on transmitting the light emitted from the lighting device.

18. The refrigerator according to claim 1 , wherein the member couples the panel and the light guide plate to each other.

19. The refrigerator according to claim 1 , wherein the panel is made of glass, and the member is made of a plastic material.

20. A home appliance comprising:
a cabinet that defines an opening; and
a door configured to open and close at least a portion of the opening, the door comprising a door body and a panel assembly disposed on the door body,
wherein the panel assembly comprises:
a lighting device configured to emit light,
a panel that defines a front surface of the door and is configured to transmit the light emitted from the lighting device,
a light guide plate disposed rearward relative to the panel and configured to guide the light emitted from the lighting device toward the panel, and
a member that is made of a material configured to transmit the light, that is disposed between the panel and the light guide plate, and that couples the panel and the light guide plate to each other, the member partitioning a space between a rear surface of the panel and a front surface of the light guide plate and being configured to transmit the light from the light guide plate to the panel.
