Abstract

Disclosed is a refrigerator including a vacuum insulation panel. The vacuum insulation panel includes a core material, a covering material disposed outside the core material to form an accommodation space in which the core material is accommodated and a first adsorbent disposed in the accommodation space to be activated at a temperature higher than room temperature and to remove at least one of gases and water present in the accommodation space.

First claim

1 . A refrigerator comprising a vacuum insulation panel, wherein the vacuum insulation panel comprises:
a core material; a covering material disposed outside the core material to form an accommodation space in which the core material is accommodated; and a first adsorbent disposed in the accommodation space to be activated at a temperature higher than room temperature and to remove at least one of gases and water present in the accommodation space.

2 . The refrigerator of claim 1 , wherein the first adsorbent comprises a metal material.

3 . The refrigerator of claim 2 , wherein the first adsorbent comprises at least one of zirconium (Zr), titanium (Ti), aluminum (Al), vanadium (V), barium (Ba), nickel (Ni), and ferrite (Fe).

4 . The refrigerator of claim 1 , wherein the vacuum insulation panel further comprises a second adsorbent disposed in the accommodation space to remove water present in the accommodation with the first adsorbent.

5 . The refrigerator of claim 4 , wherein the second adsorbent comprises at least one of calcium oxide (CaO), magnesium carbonate (MgCO 3 ), barium oxide (BaO), molecular sieve, magnesium oxide (MgO), calcium chloride (CaCl 2 ), activated carbon, silica gel, activated alumina, and zeolite.

6 . The refrigerator of claim 1 , wherein the vacuum insulation panel further comprises a porous cover which encloses the first adsorbent to prevent heat generated by the first activated adsorbent from being transferred to the core material.

7 . The refrigerator of claim 6 , wherein a material of the cover comprises at least one of organic fiber and inorganic fiber.

8 . A vacuum insulation panel comprising:
a core material; a covering material disposed outside the core material to form an accommodation space in which the core material is accommodated; and an adsorbent disposed in the accommodation space to be activated at a temperature higher than room temperature by an electromagnetic wave generated outside the covering material and to remove at least one of gases and water present in the accommodation space.

9 . The vacuum insulation panel of claim 8 , wherein the adsorbent is disposed in the accommodation space to be spaced apart from the covering material.

10 . The vacuum insulation panel of claim 8 , wherein the adsorbent comprises a metal material.

11 . The vacuum insulation panel of claim 8 , wherein the covering material comprises:
a first covering material that comprises a part through which the electromagnetic wave passes; and a second covering material coupled with the first covering material to form the accommodation space.

12 . The vacuum insulation panel of claim 11 , wherein the first covering material comprises:
a melting layer disposed to face the accommodation space in a thickness direction of the vacuum insulation panel; an inflow-prevention layer disposed on the melting layer to prevent at least one of gases and water from flowing toward the core material; and a protection layer disposed to face the melting layer with the inflow-prevention layer therebetween, wherein the inflow-prevention layer comprises at least one of silicon dioxide (SiO 2 ), alumina (Al 2 O 3 ), ethylene vinyl alcohol (EVOH), polyvinyl alcohol (PVA), and polyketone.

13 . The vacuum insulation panel of claim 12 , further comprising a shielding layer disposed in the accommodation space to be positioned between the core material and the melting layer.

14 . The vacuum insulation panel of claim 13 , further comprising a path on which the electromagnetic wave moves toward the adsorbent,
wherein a part of the shielding layer positioned on the path is formed of a material that less absorbs the electromagnetic wave than the adsorbent.

15 . The vacuum insulation panel of claim 14 , wherein another part of the shielding layer positioned outside the path comprises a metal material.

16 . The vacuum insulation panel of claim 13 , further comprising a path on which the electromagnetic wave moves toward the adsorbent,
wherein the shielding layer is discontinuously disposed in a longitudinal direction of the vacuum insulation panel to be positioned outside the path.

17 . A vacuum insulation panel comprising:
a core material; a covering material disposed outside the core material to form an accommodation space in which the core material is accommodated; and a first adsorbent disposed in the accommodation space to be spaced apart from the covering material and heated at a temperature higher than room temperature to remove at least one of gases and water present in the accommodation space.

18 . The vacuum insulation panel of claim 17 , wherein the first adsorbent is activated at a temperature higher than room temperature by an electromagnetic wave generated outside the covering material.

19 . The vacuum insulation panel of claim 18 , wherein at least one part of the covering material has a lower electromagnetic wave absorption rate than that of the first adsorbent.

20 . The vacuum insulation panel of claim 18 , further comprising an electromagnetic wave movement path on which the electromagnetic wave moves toward the first adsorbent to be transferred to the first adsorbent,
wherein the covering material comprises: a first covering material that comprises a part through which the electromagnetic wave passes; and a second covering material coupled with the first covering material to form the accommodation space.
