Abstract

Disclosed herein are a vacuum insulation panel having an improved structure which may improve durability by minimizing a folding process, and a refrigerator including the same.
The vacuum insulation panel includes a core material, a first outer skin material that is arranged to form an outer surface of the core material, a second outer skin material that has a gap and forms the other outer surface of the core material, and is disposed to face the first outer skin material, and a third outer skin material that is provided to connect the first outer skin material and the second outer skin material and to be variable in accordance with the gap.

First claim

What is claimed is:

1 . A vacuum insulation panel comprising:
a core material; a first outer skin material that is disposed to form an outer surface of the core material; a second outer skin material that has a gap and forms the other outer surface of the core material, and is disposed to face the first outer skin material; and a third outer skin material that is provided to connect the first outer skin material and the second outer skin material and to be variable in accordance with the gap.

2 . The vacuum insulation panel according to claim 1 , wherein the third outer skin material includes a first connection portion that is formed to be connected to the first outer skin material and a second connection portion that is formed to be connected to the second outer skin material, and the first connection portion and the second connection portion are provided to be overlapped with each other.

3 . The vacuum insulation panel according to claim 2 , wherein the first connection portion and the second connection portion include a creased line that is formed therebetween.

4 . The vacuum insulation panel according to claim 3 , wherein the creased line is provided to be positioned at any one of an inner side and an outer side of the first outer skin material and the second outer skin material.

5 . The vacuum insulation panel according to claim 3 , wherein the third outer skin material is formed as a pair so as to form at least two side surfaces of a plurality of surfaces.

6 . The vacuum insulation panel according to claim 1 , wherein the third outer skin material includes a wrinkled portion.

7 . The vacuum insulation panel according to claim 1 , wherein the third outer skin material includes at least one of a metal foil outer skin material and a metal vapor-deposited outer skin material.

8 . The vacuum insulation panel according to claim 1 , wherein the first outer skin material and the second outer skin material include any one of a metal foil outer skin material, a metal vapor-deposited outer skin material, an organic coated outer skin material, an inorganic coated outer skin material, and an organic and inorganic hybrid coated outer skin material.

9 . The vacuum insulation panel according to claim 1 , wherein the first outer skin material includes any one of a metal foil outer skin material, a metal vapor-deposited outer skin material, an organic coated outer skin material, an inorganic coated outer skin material, and an organic and inorganic hybrid coated outer skin material.

10 . The vacuum insulation panel according to claim 1 , wherein the second outer skin material includes any one of a metal foil outer skin material, a metal vapor-deposited outer skin material, an organic coated outer skin material, an inorganic coated outer skin material, and an organic and inorganic hybrid coated outer skin material.

11 . The vacuum insulation panel according to claim 1 , wherein the core material includes any one of organic fibers and inorganic fibers.

12 . The vacuum insulation panel according to claim 1 , wherein a length of the core material is in the range of 0.1 to 300 mm, and a diameter of the core material is in the range of 0.1 to 10 um.

13 . The vacuum insulation panel according to claim 1 , further comprising:
an adsorbent that is provided inside the core material and adsorbs at least one of gas and moisture flowing into the core material.

14 . The vacuum insulation panel according to claim 13 , wherein in the adsorbent, calcium oxide (CaO) is included at 50% or less of a weight of the vacuum insulation panel.

15 . The vacuum insulation panel according to claim 13 , wherein the first outer skin material, the second outer skin material, and the third outer skin material are adhered to one another by fusion or adhesion.

16 . A vacuum insulation panel comprising:
a core material; a first outer skin material that is disposed outside the core material; and a second outer skin material that is coupled to the first outer skin material to form a receiving space inside of which the core material is accommodated, wherein the second outer skin material is formed with a different size from a size of the first outer skin material, and includes a creased portion that is provided to enable the size of the second outer skin material to be variable.

17 . The vacuum insulation panel according to claim 16 , wherein the first outer skin material and the second outer skin material are adhered to each other along edges of the first outer skin material by fusion or adhesion.

18 . The vacuum insulation panel according to claim 16 , wherein the creased portion includes a first connection portion, a second connection portion that is connected to the first connection portion, and a creased line that is formed between the first connection portion and the second connection portion.

19 . The vacuum insulation panel according to claim 18 , wherein the first connection portion and the second connection portion are formed so as to be overlapped with each other with respect to the creased line.

20 . The vacuum insulation panel according to claim 19 , wherein the creased line is positioned outside the second outer skin material.
