Refrigerator
A refrigerator includes a cabinet, a door opening/closing the cabinet and having an opening that is penetrated in a front/rear direction, a transparent panel assembly mounted to cover the opening and through which the inside of the refrigerant is seen, and a lighting member provided in the door or the cabinet to brighten a rear side of the transparent panel assembly. The transparent panel assembly includes a front panel defining an outer appearance of a front surface, a rear panel defining an outer appearance of a rear surface, a spacer made of a metal material and disposed between the front panel and the rear panel to define a periphery of the transparent panel assembly. A heater mounting part on which a heater is mounted is disposed on the spacer, and when the heater generates heat, one side of the front panel, which comes into contact with the spacer, is heated.
1. A refrigerator comprising:
a cabinet defining a storage space;
a door configured to open and close the storage space and including an outer plate that defines an opening and that provides a door liner at a rear side of the outer plate;
a transparent panel assembly mounted on the opening of the outer plate and defining an external appearance of the door, the transparent panel assembly comprising:
a front panel defining an outer appearance of a front surface of the transparent panel assembly and made of a transparent material,
a rear panel spaced apart from the front panel,
an outer spacer disposed between the front panel and the rear panel, defining a space, and connected to the outer plate,
a display light disposed within the space defined by the outer spacer and mounted on the outer spacer, and
a light guide plate disposed within the space defined by the outer spacer and configured to guide light emitted from the display light; and
an insulation material disposed in an insulation space defined by the outer plate, the door liner, and the outer spacer,
wherein the outer plate comprises:
a first part defining a portion of a side surface of the door, and
a second part extending from the first part, including a mounting part configured to receive the front panel, and contacting the outer spacer, and
wherein the outer plate and the outer spacer are made of a metal material that is configured to transfer, from the outer spacer to the outer plate through a contact portion of the second part and the outer spacer, heat generated from the display light.
2. The refrigerator according to claim 1 , wherein the display light is mounted on the outer spacer and configured to emit light toward an end of the light guide plate.
3. The refrigerator according to claim 2 , wherein the display light is disposed between the end of the light guide plate and an inner surface of the outer spacer.
4. The refrigerator according to claim 3 , wherein the outer spacer has a rectangular shape such that the outer spacer connects a rear surface of the front panel and a front surface of the rear panel to define a circumferential surface of the transparent panel assembly, and
wherein the display light is mounted on the inner surface of the outer spacer.
5. The refrigerator according to claim 2 , wherein the display light comprises a pair of display lights disposed at ends of the light guide plate such that the light guide plate is disposed between the pair of display lights.
6. The refrigerator according to claim 1 , further comprising an adhesive member provided on the outer spacer to couple the outer spacer to the front panel or the rear panel such that the heat from the outer spacer is transferred to the front panel or the rear panel.
7. The refrigerator according to claim 1 , wherein the transparent panel assembly further comprises a display provided between the front and the rear panels, and
wherein the light guide plate is provided at a rear side of the display and configured to diffuse light irradiated from the display light.
8. The refrigerator according to claim 1 , further comprising a coupling member configured to couple the outer spacer to the second part of the outer plate.
9. The refrigerator according to claim 1 , further comprising a sealant provided on a circumferential surface of the outer spacer,
wherein the sealant is disposed at the contact portion of the second part of the outer plate and the outer spacer.
10. The refrigerator according to claim 9 , further comprising a display light cable connected to the display light and comprising a flexible film cable,
wherein the display light cable passes through the sealant and extends along a circumferential surface of the transparent panel assembly.
11. The refrigerator according to claim 1 , wherein the opening is defined by the outer plate and the door liner, and
wherein the transparent panel assembly is provided at the opening.
12. The refrigerator according to claim 11 ,
wherein the insulation material is disposed at a circumferential surface of the transparent panel assembly.
13. The refrigerator according to claim 12 , further comprising:
a heater mounting part protruding from the outer spacer toward the insulation material and having a groove that is recessed at an end of the heater mounting part; and
a heater inserted in the groove to allow heat generated from the heater to transfer to the front panel or the rear panel via the outer spacer and the outer plate.
14. The refrigerator according to claim 1 , wherein the mounting part of the outer plate comprises a step recessed from a front surface of the door, and
wherein an edge of the front panel is seated on the step.
15. The refrigerator according to claim 14 , wherein the edge of the front panel contacts the step.
16. The refrigerator according to claim 14 , wherein a height of the step in a recessed direction corresponds to a thickness of the front panel in the recessed direction.
