VACUUM HEAT INSULATION HOUSING AND REFRIGERATOR

To provide a vacuum heat insulation housing capable of improving productivity and maintaining heat insulation performance for a long period of time.SOLUTION: A vacuum heat insulation housing includes an outer plate 3a, an inner plate 3c, and a vacuum heat insulation body 3b disposed inside the outer plate 3a and the inner plate 3c. The vacuum heat insulation body 3b is provided with a core material 3bc and an adsorbing member 3bb in its inner part. The adsorbing member 3bb is disposed on the high-temperature side of the vacuum heat insulation body 3b and is structured to vacuum-seal the inner part thereof with a seal member 3ba and a base member 3bd, so that the adsorbing member 3bb disposed on the core material inside the vacuum heat insulation body is disposed on the outer plate side (high-temperature side) of the core material, and thereby a refrigeration chamber door 3 is made to have a high adsorption rate due to the adsorption rate of the adsorbing member 3bb and an environmental temperature feature, and the degree of vacuum in the vacuum heat insulation body can be maintained for a long period of time in a condition where the refrigerator is assembled and operated.SELECTED DRAWING: Figure 12 【課題】生産性の向上と、断熱性能を長期に保つことができる真空断熱筐体を提供することを目的とする。【解決手段】外板３ａと、内板３ｃと、外板３ａと内板３ｃの内部に配置された真空断熱体３ｂとを備えたもので、真空断熱体３ｂは、内部に芯材３ｂｃと吸着部材３ｂｂとを備え、吸着部材３ｂｂは真空断熱体３ｂの高温側に配置され、シール部材３ｂａとベース部材３ｂｄとで内部を真空密閉した構造としたことにより、真空断熱体内の芯材に配置された吸着部材３ｂｂは、芯材の外板側（高温側）に配置されているので、冷蔵室扉３は、吸着部材３ｂｂの吸着速度と環境温度特性から、吸着速度を速くでき、冷蔵庫が組み立てられて、冷蔵庫を運転した状態で真空断熱体内の真空度を長期に亘って維持することができる。【選択図】図１２
