Abstract

A vacuum adiabatic body includes a first plate; a second plate; a seal; a support; and an exhaust port, wherein an extension tab extending toward the third space to be coupled to the support is provided to at least one of the first and second plates, and the extension tab extends downward from an edge portion of the at least one of the first and second plates.

First claim

What is claimed is:

1 . A vacuum adiabatic body comprising:
a first plate; a second plate; a vacuum space provided between the first plate and the second plate; and a support configured to maintain a distance between the first plate and second plate, the support being disposed next to the first plate; a fixing bracket extending from the support, wherein the first plate extends in a direction of a width of the vacuum space and has an end portion of the first plate; and the fixing bracket extends in a direction of a height of the vacuum space such that a movement of the support in a direction of the width of the vacuum space is limited, wherein the support includes at least two bars and a support plate connecting the at least two bars to each other such that the at least two bars are placed next to the first plate together, and wherein the fixing bracket includes a first fixing bracket contacting the end portion of the first plate and a second fixing bracket surrounding the end portion of the first plate.

2 . The vacuum adiabatic body according to claim 1 , wherein the support plate is provided in a plate shape, or in a lattice shape such that an area that the support plate contacts the first plate is decreased, thereby reducing heat transfer.

3 . The vacuum adiabatic body according to claim 1 , wherein the fixing bracket extends upward from an edge of the support.

4 . The vacuum adiabatic body according to claim 1 .
wherein the first plate has an extending part extending from an end portion of the first plate in a direction of the height of the vacuum space; wherein the two bars extend in a direction of the height of the vacuum space, and the support plate extends in a direction of the width of the vacuum space so that the support plate supports a gap between the two bars, and wherein the extending part is the end portion of the first plate.

5 . The vacuum adiabatic body according to claim 4 , wherein the support plate covers both the adjacent two bars and a gap between the adjacent two bars.

6 . The vacuum adiabatic body according to claim 4 , wherein the two bars are disposed between the first plate and the second plate and connected to the support plate.

7 . The vacuum adiabatic body according to claim 4 , wherein the fixing bracket extends upward from an edge of the support.

8 . A vacuum adiabatic body comprising:
a first plate; a second plate; a vacuum space provided between the first plate and the second plate; a support configured to maintain a distance between the first plate and second plate, the support being disposed next to the first plate; and a fixing bracket extending from the support, wherein the support includes a support plate extending longer than a height of the vacuum space in a direction of a width of the vacuum space such that a deformation of the first plate in a direction of the height of the vacuum space is reduced, wherein the first plate extends in a same direction as the support plate and has an end portion of the first plate, wherein the fixing bracket extends in a direction of the height of the vacuum space such that a movement of the support plate in a direction of the width of the vacuum space is limited, and wherein a groove into which the end portion of the first plate is inserted is formed in the support plate such that the end portion of the first plate is coupled to the fixing bracket.

9 . The vacuum adiabatic body according to claim 8 , wherein the fixing bracket contacts with the first plate.

10 . The vacuum adiabatic body according to claim 8 , wherein the support plate is provided in a plate shape, or in a lattice shape such that an area that the support plate contacts the first plate is decreased, thereby reducing heat transfer.

11 . The vacuum adiabatic body according to claim 8 , wherein the support plate contacts with an extending part extending from the first plate in order to maintain the supporting structure of the support plate and the first plate.

12 . The vacuum adiabatic body according to claim 8 , wherein the support plate includes a plurality of connection ribs.

13 . The vacuum adiabatic body according to claim 8 , wherein the support further includes a plurality of bars disposed between the first plate and the second plate and connected to the support plate.

14 . A vacuum adiabatic body comprising:
a first plate; a second plate; a vacuum space provided between the first plate and the second plate; and a support configured to maintain a distance between the first plate and second plate, the support being disposed next to the first plate; and a fixing bracket extending from the support, wherein the support includes a bar that extends in a direction of a height of the vacuum space, the bar having a smaller width than a height, wherein the first plate extends in a direction of a width of the vacuum space, wherein the fixing bracket extends in a same direction as the bar such that a movement of the bar in a direction of the width of the vacuum space is limited in order to reduce a destruction of the bar, and wherein the fixing bracket extends upward from an edge of the support and the fixing bracket contacts with the first plate.

15 . The vacuum adiabatic body according to claim 14 , wherein the bar comprises adjacent two bars that extend in a direction of the height of the vacuum space, and
wherein the support further includes a support plate extending in a direction of the width of the vacuum space so that the support plate supports a gap between the adjacent two bars.

16 . The vacuum adiabatic body according to claim 14 wherein the fixing bracket contacts with a side of the first plate.

17 . The vacuum adiabatic body according to claim 16 , wherein a material of the support includes a resin or a material selected from the group consisting of PC, glass fiber PC, low outgassing PC, PPS, and LCP.
