<p><P>PROBLEM TO BE SOLVED: To improve heat insulating performance and to secure long-term reliability while increasing an installation area of a vacuum heat insulating material in a refrigerator. <P>SOLUTION: This refrigerator 1 is provided with a heat insulating housing 20 constituted by disposing a core material, and the vacuum heat insulating material 50 formed by receiving an adsorbent in a shell material and vacuumed inside into the three-dimensional shape along a plurality of faces of an outer case 21 or an inner case 22, in a space formed by the outer case 21 and the inner case 22, and by charging foam insulating material 23 therein. The shell material of the vacuum heat insulating material 50 is formed by a resin shell material injection-molded into the three-dimensional shape along the plurality of faces of the outer case 21 or the inner case 22. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
