Core of vacuum insulation member and vacuum insulation member using the same
A core of a vacuum insulation member and a vacuum insulation member using the same are disclosed. The core of a vacuum insulation member includes: a plurality of plates which are spaced apart from each other; and a support member supporting the plurality of plates between the plates.
1. A core of a vacuum insulation member, the core comprising:
a plurality of plates which are spaced apart from each other; and a support member supporting the plurality of plates between the plates,
wherein the support member comprises a plurality of posts extending between a pair of the plates,
wherein a plurality of through portions are formed on at least one of the plates,
wherein the plates including the through portions have a lattice form,
wherein a portion of the lattice has a cutaway portion
wherein the cutaway portion is positioned at an end portion of each post, and
wherein the posts positioned at either side of the plates do not overlap with each other in a thicknesswise direction of the plates.
2. The core of claim 1 , wherein the posts have a circular or polygonal section.
3. The core of claim 2 , wherein a junction plate extending to be parallel to the plurality of plates is formed on at least one of the end portions of each post.
4. The core of claim 3 , wherein each post has a channel-like shape when viewed from a side.
5. The core of claim 1 , wherein the plurality of plates comprises uppermost and lowermost plates, and the through portions are formed on plates other than the uppermost and the lowermost plates.
6. The core of claim 1 , wherein the posts are positioned at each crossing of the lattice form.
7. A vacuum insulation member comprising: an envelope; a core encapsulated by the envelope; and a getter positioned at the core, wherein the core is one of the cores described in claim 1 .
8. A core of a vacuum insulation member, the core comprising: first and second plates having a plate form; one or a plurality of intermediate plates disposed between the first and second plates; and posts disposed between the plates to support the plates,
wherein a plurality of through holes are formed on the intermediate plates,
wherein the intermediate plates have a lattice form,
wherein a portion of the lattice has a cutaway portion,
wherein the cutaway portion is positioned at an end portion of each of the post, and
wherein the posts positioned at either side of the plates do not overlap in a thicknesswise direction of the plates.
9. The core of claim 8 , wherein each of the posts is disposed at each crossing of the lattice form.
