In addition, seal member 44 has occlusive part 442 and claw 443,444 with maintaining part 441 opposition sides.Seal member 44 utilizes occlusive part 442 and claw 443 to clamp inner part 31, and utilizes occlusive part 442 and claw 444 to clamp exterior part 32, thereby fixing with inner part 31 and exterior part 32.And then seal member 44 has strain portion 445 between maintaining part 441 and occlusive part 442.Strain portion 445 is to the thickness direction strain of vacuum insulation panel 33.Thus, the error of vacuum insulation panel 33 gauges when seal member 44 tolerables are manufactured vacuum insulation panel 33.
Vacuum insulation panel 33 is formed as plate shape, utilizes the resin binders such as hot melt to engage with inner part 31 and exterior part 32 fixing.Now, vacuum insulation panel 33 as shown in Figure 3, with around engage with exterior part 32 under the state that leaves of protuberance 34 and middle protuberance 35 fixing.Vacuum insulation panel 33 is set, itself and radiating tube 36 and metal adhesive tape 41 is left, and do not contact with metal adhesive tape 41 with radiating tube 36.
Vacuum insulation panel 33, as shown in Figure 4 and Figure 5, is that core 45 is contained in to bag 46, and its inner vacuum exhaust Bing Minus means of press seals is formed.Core 45 is preshaped by the stacking material of the inorfils such as such as glass fibre is plate shape.In addition, bag 46 is by two stacked films with gas barrier property are overlapped, and to its welding around, and form bag-shaped.For bag 46, in the time being formed by two kinds of different stacked films of characteristic, comprise inner side stacked film 461 and outside stacked film 462.
Inner side stacked film 461 and outside stacked film 462 are the layers for obtaining gas barrier property, now, utilize resin molding to clamp metal level, more stacked various kinds of resin film and forming.Be aluminium foil layer or aluminium-vapour deposition layer by what make inner side stacked film 461 and outside stacked film 462 for obtaining the metal level of gas barrier property, can bring into play respectively different characteristics.At this, the difference of aluminium foil layer and aluminium-vapour deposition layer is described.Generally, because aluminium-vapour deposition layer is in a vacuum the film as mother metal to be carried out to evaporation formation, therefore thickness is thinner compared with aluminium foil layer.Therefore, aluminium-vapour deposition layer, low with aluminium foil layer phase specific thermal conductivity, heat-proof quality is good.On the other hand, because aluminium foil layer is to utilize two films clip the aluminium foil that for example calendering forms and form through pressing, therefore its thickness is thicker compared with aluminium-vapour deposition layer.Thereby aluminium foil layer gas barrier property compared with aluminium-vapour deposition layer is good, and endurance quality might as well.
In the present embodiment, as the metal level for obtaining gas barrier property, the inner side stacked film 461 that is positioned at inner part 31 sides has aluminium-vapour deposition layer.On the other hand, as the metal level for obtaining gas barrier property, the outside stacked film 462 that is positioned at exterior part 32 sides has aluminium foil layer.Now, the mask of radiating tube 36 sides of vacuum insulation panel 33 has the aluminium foil layer of excellent in durability.Therefore, can reduce because contacting vacuum insulation panel 33 is caused to damage with radiating tube 36.In addition, the mask of storeroom 12～16 sides of vacuum insulation panel 33 has the aluminium-vapour deposition layer that thermal conductivity is low and heat-proof quality is good.Therefore, can suppress the cold air of storeroom 12～16 through bag 46 surface conductive of vacuum insulation panel 33, from the roundabout so-called heat bridge effect to exterior part 32 sides of inner part 31 sides.
Bag 46 is that inner side stacked film 461 and outside stacked film 462 are overlapped, and is formed as bag-shaped to its welding around.Now, in the outer edge of vacuum insulation panel 33, the surrounding of bag 46 forms with the form highlighting from core 45 ear 463 that welding is used.Ear 463, to exterior part 32 folding of turning on one's side, is contained in to protuberance 341 inner sides around, front side as the front end edge of right side thermal wall 24.Though do not represent its detail in figure, utilize adhesive or metal adhesive tape etc., ear 463 is fixed along the face of the outside stacked film 462 of exterior part 32 sides.Now, ear 463 is left with radiating tube 36 and metal adhesive tape 41.And ear 463 is left with exterior part 32.Therefore,, because of the stage portion 464 that turnover ear 463 forms, can not contact with exterior part 32.
According to said structure, the thermal wall of the formation opening of heat insulating box 11, in left side thermal wall 23, right side thermal wall 24, top thermal wall 25 and bottom thermal insulation wall 26, the at least thermal wall 23,24 of left and right, exterior part 32 have outstanding to the extroversion of each storeroom 12～16 around protuberance 34 and middle protuberance 35.And, in the inside of the thermal wall 23,24 of this left and right, between exterior part 32 and inner part 31, be provided with and around protuberance 34 and the interior side contacts of middle protuberance 35, form the radiating tube 36 of a part for kind of refrigeration cycle.
Thus, for for example right flank of refrigerator 10, the lateral surface of right side thermal wall 24 and the wall in room etc. are contacted under the situation arranging, because protuberance 34 around contact with the wall in room with middle protuberance 35, and around formation not protuberance 34 and the part of middle protuberance 35 and the between the walls in room formation space.That is to say, the overall situation about contacting with the wall in room of lateral surface of the right side thermal wall 24 of refrigerator 10 can not occur, thus, guarantee around radiating tube 36, to there is the space for dispelling the heat.Therefore,, for refrigerator 10, even in the time that the formation right side thermal wall 24 of its right flank and the wall in room etc. closely connect or contact configuration, also can suppress the situation that causes radiating efficiency to decline because of heat accumulation around radiating tube 36.And, for the structure left side thermal wall 23 identical with right side thermal wall 24, also can obtain effect same as described above.
