Description

上記課題を解決するために、本発明の冷蔵庫は、外箱と内箱との間に発泡系断熱材と真空断熱材とを備えた冷蔵庫において、前記真空断熱材は、有機繊維を含む芯材と、該芯材を覆い内部を減圧して封止したガスバリヤ性を有する外被材と、を有し、前記外被材の表面を覆う断熱部材を備え、前記真空断熱材は前記断熱部材を介して前記外箱及び前記内箱から離れた状態で配置され、前記断熱部材は前記芯材の耐熱温度よりも低い温度で固形状態となることを特徴とする。 In order to solve the above problems, the refrigerator of the present invention is a refrigerator provided with a foam heat insulating material and a vacuum heat insulating material between an outer box and an inner box, wherein the vacuum heat insulating material is a core material containing organic fibers. And a jacket member having a gas barrier property that covers and seals the inside of the core member, and includes a heat insulating member that covers a surface of the jacket member, and the vacuum heat insulating member includes the heat insulating member. are arranged in a state separated from the outer box and the inner box through the heat insulating member is characterized Rukoto such a solid state at a temperature lower than the heat resistant temperature of the core material.

また、前記芯材はポリスチレン，ポリエチレンテレフタレート，ポリプロピレンの少なくともいずれかを含む繊維集合体であり、前記断熱部材は軟質ウレタンフォーム又はポリエチレンフォームであり、且つ前記真空断熱材と接する面及び前記外箱又は前記内箱と接する面に接着層を有することを特徴とする。 Further, the core material is a fiber assembly including at least one of polystyrene, polyethylene terephthalate, and polypropylene, the heat insulating member is a soft urethane foam or polyethylene foam, and the surface in contact with the vacuum heat insulating material and the outer box or characterized Rukoto which have a bonding layer on the surface in contact with the inner box.

また、前記断熱部材は前記外箱又は前記内箱と接する面と反対側の前記発泡系断熱材側の面に熱拡散層を備えたことを特徴とする。 Further, the heat insulating member includes a heat diffusion layer on a surface on the foamed heat insulating material side opposite to a surface in contact with the outer box or the inner box.

また、前記芯材はポリスチレン，ポリエチレンテレフタレート，ポリプロピレンの少なくともいずれかを含む繊維集合体であり、前記断熱部材は有機繊維，無機繊維，発泡樹脂，天然素材のいずれかであり、前記接着層は合成樹脂フィルムであり、前記熱拡散層は金属箔，金属薄板，金属層を含む樹脂ラミネートフィルムのいずれかであることを特徴とする。 Further, the core material is a fiber assembly including at least one of polystyrene, polyethylene terephthalate, and polypropylene, the heat insulating member is any one of organic fiber, inorganic fiber, foamed resin, and natural material, and the adhesive layer is synthesized. It is a resin film, and the heat diffusion layer is any one of a metal foil, a metal thin plate, and a resin laminate film including a metal layer.
