Abstract

Official abstract text for this publication.

A refrigerator includes a cabinet, in which a storage space is defined, and a door configured to open and close the storage space. The door includes a door body and a panel assembly mounted in front of the door body. The panel assembly includes a lighting device configured to irradiate light, a panel which is configured to define a front surface of the door and through which light is transmitted, a light guide plate provided behind the panel to guide the light irradiated from the lighting device to the panel, and an upper bracket provided above the panel to define a top surface of the panel assembly. The light guide plate extends more upward than an upper end of the panel, and an extending upper end of the light guide plate is accommodated in the upper bracket.

First claim

Opening claim text (preview).

What is 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 and a panel assembly disposed at a front side of 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 transmit the light, a light guide plate disposed rearward relative to the panel and configured to guide the light emitted from the lighting device to the panel, and an upper bracket that is disposed above the panel and defines a top surface of the panel assembly, the upper bracket accommodating an upper end of the light guide plate that extends upward relative to an upper end of the panel. 2 . The refrigerator according to claim 1 , wherein the upper bracket defines a groove that is recessed from a bottom surface of the upper bracket and accommodates the upper end of the light guide plate facing the bottom surface of the upper bracket. 3 . The refrigerator according to claim 2 , wherein the groove of the upper bracket is recessed upward relative to a front end of the bottom surface of the upper bracket. 4 . The refrigerator according to claim 2 , wherein the light guide plate is made of a material that expands and contracts by heat, and wherein the groove is recessed upward relative to a maximum expansion height of the light guide plate. 5 . The refrigerator according to claim 1 , further comprising a mounting member configured to transmit light and disposed between the panel and the light guide plate, wherein the light guide plate is disposed on the mounting member. 6 . The refrigerator according to claim 5 , wherein the mounting member comprises: a front surface portion that has a plate shape and is disposed between the panel and the light guide plate, the front surface portion facing the panel; and side surface portions that extend rearward from lateral side ends of the front surface portion and are coupled to lateral side ends of the light guide plate, respectively. 7 . The refrigerator according to claim 6 , wherein an upper end of the front surface portion is disposed at or above the upper end of the panel. 8 . The refrigerator according to claim 6 , wherein the upper bracket accommodates an upper end of the front surface portion. 9 . The refrigerator according to claim 6 , wherein the upper bracket defines a groove at a bottom surface thereof, and wherein an interior of the groove is partitioned into: a light guide plate accommodation portion that accommodates the upper end of the light guide plate; and a mounting member accommodation portion that is disposed forward relative to the light guide plate accommodation portion and accommodates an upper end of the front surface portion. 10 . The refrigerator according to claim 9 , wherein a horizontal length of the mounting member accommodation portion is greater than a horizontal length of the light guide plate accommodation portion. 11 . The refrigerator according to claim 9 , wherein a shape of the groove corresponds to a cross-sectional shape of the front surface portion and the light guide plate to thereby receive the upper ends of the front surface portion and the light guide plate. 12 . The refrigerator according to claim 6 , wherein the side surface portions extend in a vertical direction along left and right ends of the light guide plate, respectively, wherein each of the side surface portions defines a light guide plate insertion space that extends in the vertical direction and receives one of the left end or the right end of the light guide plate, wherein the upper end of the light guide plate passes through upper ends of the side surface portions and is disposed above the upper ends of the side surface portions, and wherein a lower end of the light guide plate passes through lower ends of the side surface portions and is disposed below the lower ends of the side surface portions. 13 . The refrigerator according to claim 6 , wherein the upper bracket defines a groove at a bottom surface thereof, the groove receiving an upper end of the front surface portion of the mounting member, and wherein an upper end of each of the side surface portions is stepped downward with respect to the upper end of the front surface portion and supports the bottom surface of the upper bracket. 14 . The refrigerator according to claim 1 , wherein the upper bracket comprises a bracket protrusion that protrudes forward from a front end of the upper bracket, and wherein at least a portion of the bracket protrusion extends downward and defines a lower end of the bracket protrusion that is disposed below the upper end of the light guide plate. 15 . The refrigerator according to claim 14 , wherein the bracket protrusion extends toward the upper end of the panel and covers a front side of the upper end of the light guide plate. 16 . The refrigerator according to claim 14 , wherein the top surface of the panel assembly defined by the upper bracket comprises: a horizontal portion that extends forward from a rear end of the upper bracket; and an inclined portion that extends forward from a front end of the horizontal portion and is inclined downward with respect to the horizontal portion, and wherein the bracket protrusion protrudes downward from a front end of the inclined portion. 17 . The refrigerator according to claim 1 , wherein a lower end of the light guide plate is disposed below a lower end of the panel. 18 . The refrigerator according to claim 17 , further comprising a lower bracket that is disposed below the panel and defines a bottom surface of the panel assembly, wherein the lighting device is disposed inside the lower bracket and configured to emit light to the lower end of the light guide plate. 19 . The refrigerator according to claim 18 , wherein the lower bracket comprises a front surface portion that supports the panel, wherein the lower end of the panel is supported on an upper end of the front surface portion of the lower bracket, and wherein the lower end of the light guide plate is inserted into the lower bracket through the upper end of the front surface portion of the lower bracket. 20 . The refrigerator according to claim 18 , wherein the panel assembly further comprises a reflective layer that faces the light guide plate and is configured to reflect the light into an inside of the light guide plate, and wherein the reflective layer is disposed at each of the upper end of the light guide plate, a left end of the light guide plate, and a right end of the light guide plate.
