Abstract:
PROBLEM TO BE SOLVED: To provide a refrigerator preventing occurrence of production failure by preventing peeling off of a vacuum heat insulating panel during manufacturing of a door. SOLUTION: The refrigerator includes a refrigerator body having an opened front face and a storage compartment formed inside and the door 37 closing a front face opening of the refrigerator body. The door 37 includes: a door face material 52 arranged on the refrigerator exterior side; a door inner plate 54 arranged on the refrigerator interior side; and a heat insulating part 60 sandwiched between the door face material 52 and the door inner plate 54 and having the vacuum heat insulating panel 64 and a foam heat insulating material 66 arranged therein. A reinforcement plate 62 coming into contact with the door face material 52 is arranged between the door face material 52 and the vacuum heat insulating panel 64. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a vacuum heat insulation material, remarkably improved in core material strength and having excellent surface property and heat insulation performance by binding fibers to each other caused by precipitation of solid matter on the surface of the fiber in addition to binding of fibers caused by component eluted from the fiber. SOLUTION: This vacuum heat insulation material 1 is characterized in that a core material thereof is formed of water soluble inorganic compound containing a metal element and solid at an ordinary temperature. Especially in the case of the compound used for food or fertilizer, the obtained core material is safe and little exerts an influence upon the environment. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
By using vacuum heat insulator comprising a core made of laminated sheets of an inorganic fiber having a particular shape and composition as a vacuum heat insulator for a heat insulation box, a heat insulation box excellent in long-term heat insulating property and productivity can be provided. The vacuum heat insulator can be shaped easily. Therefore, a vacuum heat insulator suitable for a required heat insulation portion can be produced easily and applied to a heat insulation box. This property can increase coverage of the vacuum heat insulator on the heat insulation box, thus improving the heat insulating property of the heat insulation box. This can improve the heat insulating property and productivity of a refrigerator, thermal storage box, cold storage box, or vending machine, and contribute to an energy saving.
Abstract:
A vacuum heat insulator includes core material (203), first member (201) having a box shape with opening (204), core material (203) being disposed in first member (201), and second member (202) that tightly closes opening (204). First member (201) includes first resin layer (21), second resin layer (22), and gas barrier layer (23), first resin layer (21) and second resin layer (22) being made of thermoplastic resin, gas barrier layer (23) being disposed between first resin layer (21) and second resin layer (22) and containing organic resin and scaly inorganic material. A content of the scaly inorganic material in gas barrier layer (23) is equal to or less than 14% by weight relative to a gross weight of gas barrier layer (23).
Abstract:
An insulated cabinet structure includes an inner liner having a plurality of walls defining a refrigerator compartment. An external wrapper includes a plurality of walls defining a refrigerator compartment receiving area. An insulation gap is formed between the walls of the inner liner and the walls of the external wrapper when the inner liner is received in the external wrapper. An insulation member is positioned within the insulation gap and includes a renewable resource component comprising about 10% to about 90% by weight of the insulation member.
Abstract:
Disclosed herein are a vacuum insulation panel having an improved structure which may improve durability by minimizing a folding process, and a refrigerator including the same. The vacuum insulation panel (100) includes a core material (110), a first outer skin material that is arranged to form an outer surface of the core material, a second outer skin material that has a gap and forms the other outer surface of the core material, and is disposed to face the first outer skin material, and a third outer skin material (310, 320, 330) that is provided to connect the first outer skin material and the second outer skin material and to be variable in accordance with the gap.
