Abstract

To provide a vacuum heat insulating material contributing to energy saving and a refrigerator using the vacuum insulating material, and a manufacturing method of the vacuum insulating material by preventing the tatal heat insulating efficiency from decreasing. The vacuum insulating material is comprised of a core material and a jacket material to cover the core material so as to seal the inside of the jacket by decompression. The ear part extruded from the core material surface of the jacket material is bent so as to overlap and contact with the vacuum insulating material surface side so that the ear part and the vacuum insulating material surface come in contact with by intervening a heat insulating member. Thereby, since the gap in which an air molecule formed in circumference of a conventional vacuum insulating material can be lessened, the total heat leakage can be reduced.

Description

technical field [0001] The present invention relates to a vacuum heat insulating material, a refrigerator using the vacuum heat insulating material, and a manufacturing method of the vacuum heat insulating material. Background technique [0002] Patent Document 1 - Japanese Unexamined Patent Application Publication No. 2001-165557 describes a conventional vacuum heat insulating material and a refrigerator using the vacuum heat insulating material. In Patent Document 1, a thin plate-shaped inorganic fiber assembly is provided as a core material in the heat insulating wall and the partition wall of the refrigerator, and then the core material is covered with an air-impermeable outer covering material and the inside is sealed. Vacuum insulation material that is evacuated to suppress the temperature rise inside the refrigerator, thereby achieving the purpose of energy saving. [0003] In the structure of the above-mentioned conventional example, after arranging the vacuum heat ...
