Abstract

A home appliance includes a refrigerator including a panel assembly. The panel assembly includes: a first panel formed of a glass material; a second panel spaced apart from the first panel and formed of a glass material; a plurality of spacers provided between the first panel and the second panel so as to maintain a gap between the first panel and the second panel, and arranged to be spaced apart from each other; a sealing member disposed between the first panel and the second panel for sealing a space between the first panel and the second panel; an exhaust hole provided in at least one of the first panel and the second panel so as to discharge air such that the space between the first panel and the second panel becomes a vacuum insulation space; and a cover member covering the exhaust hole.

First claim

What is claimed is:

1. An appliance comprising:
a cabinet having an inner space;
a lighting unit disposed within the inner space; and
a door configured to open and close at least a portion of the inner space, the door comprising (i) a frame having an opening and (ii) a panel assembly that covers the opening,
wherein the panel assembly comprises:
a first panel that is made of tinted glass and that defines a front surface of the door,
a second panel spaced apart from the first panel and made of a glass material,
a plurality of spacers disposed between the first panel and the second panel and configured to maintain a gap between the first panel and the second panel to be in a range of 0.1 mm to 1 mm,
a sealing member disposed between the first panel and the second panel and configured to seal a space defined between the first panel and the second panel,
an exhaust hole defined in the second panel and configured to allow air to be exhausted from the space defined between the first panel and the second panel,
a getter that overlaps with the exhaust hole and that is configured to absorb moisture in the space defined between the first panel and the second panel, and
a cover member inserted into the exhaust hole,

wherein the first panel comprises:
a first area positioned forward of the plurality of spacers and configured to transmit light through the tinted glass, and
a second area that surrounds the first area and that is configured to block light transmission through the tinted glass, and

wherein the second area is positioned forward of the sealing member and the exhaust hole and is defined by a printed layer on a rear surface of the first panel.

2. The appliance of claim 1 , wherein the getter is inserted into the exhaust hole.

3. The appliance of claim 1 , wherein the door further comprises an insulation material provided in a space defined by the frame and the panel assembly, and
wherein the insulation material is configured to surround the sealing member.

4. The appliance of claim 3 , wherein the insulation material is directly in contact with a rear surface of the second panel.

5. The appliance of claim 3 , wherein the insulation material is configured to surround the cover member.

6. The appliance of claim 1 , further comprising a heater that is provided at a rear side of the first panel and that faces the printed layer.

7. The appliance of claim 1 , wherein a portion of the plurality of spacers faces the printed layer.

8. An appliance comprising:
a cabinet having an inner space;
a lighting unit disposed within the inner space; and
a door configured to open and close at least a portion of the inner space, the door comprising (i) a frame having an opening and (ii) a panel assembly that covers the opening,
wherein the panel assembly comprises:
a first panel made of a glass material,
a second panel spaced apart from the first panel and made of a glass material,
a third panel made of tinted glass, the third panel defining a front surface of the door,
a plurality of spacers disposed between the first panel and the second panel and configured to maintain a gap between the first panel and the second panel,
a sealing member disposed between the first panel and the second panel and configured to seal a space defined between the first panel and the second panel,
an exhaust hole positioned at the second panel and configured to allow air to be exhausted from the space,
a cover member inserted into the exhaust hole, and
a getter that overlaps with the exhaust hole and that is configured to absorb moisture in the space defined between the first panel and the second panel,

wherein the third panel comprises:
a first area positioned forward of the plurality of spacers and configured to transmit light through the tinted glass, and
a second area that surrounds the first area and that is configured to block light transmission through the tinted glass, and

wherein the second area is positioned forward of the sealing member and the exhaust hole and has a printed layer disposed on a rear surface of the third panel.

9. The appliance of claim 8 , wherein the getter is provided in the first panel.

10. The appliance of claim 8 , wherein the gap is in a range of 0.1 mm to 1 mm.

11. The appliance of claim 8 , wherein the door further comprises an insulation material provided in a space defined by the frame and the panel assembly, and
wherein the insulation material is configured to surround the sealing member.

12. The appliance of claim 11 , wherein the insulation material is directly in contact with a rear surface of the second panel.

13. The appliance of claim 11 , wherein the insulation material is configured to surround the cover member.

14. A refrigerator comprising:
a cabinet having an inner space; and
a door configured to open and close at least a portion of the inner space, the door comprising (i) a frame having an opening and (ii) a panel assembly that covers the opening,
wherein the panel assembly comprises:
a first panel made of a glass material, the first panel defining a front surface of the door,
a second panel spaced apart from the first panel and made of a glass material,

wherein a size of the first panel is greater than a size of the second panel,
a heater mounted on a rear surface of the first panel,
a sealing member disposed between the first panel and the second panel and configured to seal a space between the first panel and the second panel,
an exhaust hole defined in at least one of the first panel or the second panel and configured to exhaust air from the space between the first panel and the second panel to define a vacuum insulation space,
a cover member configured to cover the exhaust hole, and
an insulation material provided in an insulation space defined by the frame and panel assembly,

wherein the insulation material overlaps with the second panel along a left-right direction, and
wherein an overlapping length between the insulation material and the second panel along the left-right direction is greater than a thickness of the panel assembly in a front-rear direction.

15. The refrigerator of claim 14 , wherein the first panel comprises an extended portion that extends outside of the second panel, and
wherein the heater is mounted on the extended portion.

16. The refrigerator of claim 14 , wherein the panel assembly further comprises a getter that overlaps with the exhaust hole and that is configured to absorb moisture in the space defined between the first panel and the second panel.

17. The refrigerator of claim 14 , wherein the panel assembly further comprises a plurality of spacers disposed between the first panel and the second panel and configured to maintain a gap between the first panel and the second panel to be in a range of 0.1 mm to 1 mm.

18. The refrigerator of claim 14 , wherein the insulation material is configured to surround the sealing member and the cover member.

19. The refrigerator of claim 18 , wherein the insulation material is directly in contact with a rear surface of the second panel.
