Vacuum insulation box

Abstract

The present invention relates to a vacuum insulation box. According to one aspect of the present invention, the vacuum insulation box comprises: a vacuum panel having a plurality of insulation cells arranged to have an inclined part with a one-side end portion inclined at an angle of 45 degrees or higher, and forming a development figure through a plate part that connects the insulation cells while the insulation cells are encompassed; a core material part formed inside the insulation cell so as to block heat exchange between the inner surface and the outer surface of the vacuum panel; and a close-contact part protruding from the outer surface of the inclined part in the outward direction of the inclined part so as to improve adhesion between adjacent insulation cells when the insulation cells are in contact with each other. The present invention relates to a vacuum insulation box. According to one aspect of the present invention, the vacuum insulation box comprises: a vacuum panel having a plurality of insulation cells arranged to have an inclined part with a one-side end portion inclined at an angle of 45 degrees or higher, and forming a development figure through a plate part that connects the insulation cells while the insulation cells are encompassed; a core material part formed inside the insulation cell so as to block heat exchange between the inner surface and the outer surface of the vacuum panel; and a close-contact part protruding from the outer surface of the inclined part in the outward direction of the inclined part so as to improve adhesion between adjacent insulation cells when the insulation cells are in contact with each other.

1 . A vacuum insulation box comprising:
 a vacuum panel including a plurality of insulating cells each having an inclined portion inclined at an angle of 45 degrees or more at each side and a plate part configured to enclose and connect the insulating cells and configured to form a deployed box shape;   a core provided inside the insulating cell to block heat exchange between inner and outer surfaces of the vacuum panel; and   a close contact portion protruding outward from an outer surface of the inclined portion to increase adhesion between the insulating cells that are adjacent when in contact with each other.   
     
     
         2 . The vacuum insulation box of  claim 1 , wherein the plate part includes:
 a vertical plate configured to connect the insulating cells that are disposed perpendicular to a bottom surface; and   a horizontal plate perpendicularly coupled to the vertical plate.   
     
     
         3 . The vacuum insulation box of  claim 1 , wherein the core is formed of an organic fiber, an inorganic fiber, and an inorganic material such as fumed silica, and includes a stack of trapezoidal core members whose areas decrease as the core members are stacked. 
     
     
         4 . The vacuum insulation box of  claim 1 , wherein the core includes rounded protruding surfaces protruding outward from opposite sides. 
     
     
         5 . The vacuum insulation box of  claim 1 , wherein the opposite sides of the core are inclined at the same angle of inclination as the inclined portion. 
     
     
         6 . The vacuum insulation box of  claim 1 , wherein the core includes a recess having a shape that is inwardly recessed from the opposite sides thereof. 
     
     
         7 . The vacuum insulation box of  claim 1 , wherein the insulating cell includes:
 an inner wall shaped to wrap the core; and   an outer wall spaced apart outward from the inner wall to form a space in a vacuum state.   
     
     
         8 . The vacuum insulation box of  claim 2 , wherein the plate part includes:
 a vertical body attached to outer surfaces of the insulating cells;   an adhesion member extending from each of opposite ends of the vertical body; and   a tensioning portion provided on a side of the vertical body opposite to sides on which the insulating cells are disposed and in a position where the adjacent insulating cells are in contact.   
     
     
         9 . The vacuum insulation box of  claim 3 , wherein the core member includes:
 a first core member having an integral structure, and a second core member disposed on one surface of the first core member to be spaced apart from each other, stacked on the first core member with a decreasing area, and having an inclined outer surface to form a trapezoidal shape.   
     
     
         10 . The vacuum insulation box of  claim 9 , wherein the second core member extends as a single structure. 
     
     
         11 . The vacuum insulation box of  claim 1 , further comprising:
 a fold configured to seal the core while outwardly surrounding the core inside the core, such that opposite ends of the vacuum panel are provided in an outward direction of the core so as to be bonded to each other.
