近年、地球環境問題である温暖化の対策として省エネルギー化を推進する動きが活発し断熱技術の性能進化が期待されている。従来、この種の断熱技術は、図３５に示されているように、真空断熱体１０３のガスバリア容器１０７と筐体パネル１０１とを一体化した構造にすることで断熱性能を向上させた技術が提案されている（例えば、特許文献１参照）。なお、真空断熱体とは、容器内を真空にすることで断熱性能を向上させた構造体のことをいう。 In recent years, there has been an active movement to promote energy saving as a countermeasure against global warming, which is a global environmental problem, and the performance of thermal insulation technology is expected to evolve. Conventionally, as shown in FIG. 35, this type of heat insulation technology is a technology that improves the heat insulation performance by integrating the gas barrier container 107 of the vacuum heat insulator 103 and the housing panel 101. It has been proposed (see, for example, Patent Document 1). In addition, a vacuum heat insulating body means the structure which improved the heat insulation performance by evacuating the inside of a container.
しかしながら、前記従来の構成は、真空引き用のフランジ部１０５の密閉封止を主な課題とするもので、ガスバリア容器１０７と筐体パネル１０１とを一体化した構造としか記載されておらず、真空度を長期間保つことのできる具体的な一体化について手段は明記されていない。そして、ガスバリア容器１０７と、筐体パネル１０１の間に微小な空間が存在した場合には、ガスバリア容器１０７内へ空気や水蒸気などのガスが進入することを完全に防止することが困難であり、長期間真空度を保つことで、断熱性能を保つことが困難であるという課題があった。 However, the above-described conventional configuration is mainly intended to hermetically seal the flange portion 105 for vacuuming, and only describes a structure in which the gas barrier container 107 and the housing panel 101 are integrated. Means for specific integration that can maintain the degree of vacuum for a long time is not specified. And, when there is a minute space between the gas barrier container 107 and the housing panel 101, it is difficult to completely prevent gas such as air and water vapor from entering the gas barrier container 107, There existed a subject that it was difficult to maintain heat insulation performance by maintaining a vacuum degree for a long period of time.
本発明は、前記従来の課題を解決するもので、使用環境温度や使用箇所によって、ガスバリア構造の最適化を図ることで、安価な構成で長期間真空度を保証し、断熱性能も保証できる内装筐体部材や外観筐体部材として使用可能な真空断熱筐体を提供することを目的とする。 The present invention solves the above-mentioned conventional problems, and by optimizing the gas barrier structure according to the use environment temperature and the use location, the interior can guarantee the degree of vacuum for a long period of time with a low-cost configuration and also guarantee the heat insulation performance.

以上、様々な形態のガスバリア容器の壁構造を紹介したが、要求されるガスバリア性能に対応して最適な構造のものを選択すれば良い。 As described above, the wall structures of various types of gas barrier containers have been introduced. However, an optimal structure corresponding to the required gas barrier performance may be selected.
次に、図３を用いてガスバリア容器の材料であるガスバリア樹脂の使用環境温度とガス透過度の関係を説明する。ガスバリア樹脂材料のガス透過度は、周囲環境が高温側になるほど、材料の分子間に微細な隙間を生じ悪化させ、低温度側では逆に、分子間の隙間が減少するので、良化する傾向となる。つまり、高温になる程ガスバリア性能が劣化する特徴がある。 Next, the relationship between the operating temperature of the gas barrier resin, which is the material of the gas barrier container, and the gas permeability will be described with reference to FIG. The gas permeability of the gas barrier resin material tends to improve because the higher the ambient environment, the worse the fine gaps between the molecules of the material, and conversely, the gaps between the molecules decrease on the low temperature side. It becomes. That is, the gas barrier performance is deteriorated as the temperature becomes higher.
故に、使用箇所や使用環境の温度帯によって、最適なガスバリア性能を満たすガスバリア容器の厚みや材質を選択することで断熱性能の最適化と低コスト化を図ることができる。 Therefore, the heat insulation performance can be optimized and the cost can be reduced by selecting the thickness and material of the gas barrier container that satisfies the optimum gas barrier performance depending on the temperature zone of the use location and the use environment.
具体的には、冷蔵庫１の真空断熱体を使用している箇所により、周囲温度が異なり、例えば冷蔵庫１の外気温度を２０℃とすると、冷蔵庫本体２は、周囲温度の高温側で圧縮器８の影響で約４０℃と最高温度となり、低温側で蒸発器９の影響で内部温度約−３０℃と最低温度となるので、周囲温度とガス透過度の関係図から図３のＥ範囲となりＥ範囲を満たすものを選択すればよい。 Specifically, the ambient temperature varies depending on the location where the vacuum insulator of the refrigerator 1 is used. For example, when the outside air temperature of the refrigerator 1 is 20 ° C., the refrigerator body 2 is connected to the compressor 8 on the high temperature side of the ambient temperature. The maximum temperature is about 40 ° C. due to the influence of the evaporator, and the minimum temperature is about −30 ° C. due to the influence of the evaporator 9 on the low temperature side. What is necessary is just to select what satisfy | fills a range.
同様に、冷蔵室蓋体３では、冷蔵室空間部１１の室温により、高温側の外気温度が約２０℃で、低温側が約２℃となるので、周囲温度とガス透過度の関係図からＢ範囲となり、製氷室蓋体４では、製氷室空間部１２の室温により、高温側の外気温度が約２０℃で、低温側が約−１８℃となるので、周囲温度とガス透過度の関係図からＡ範囲となり、野菜室蓋体５では、野菜室空間部１３の室温により高温側の外気温度が約２０℃で、低温側が約５℃となるので、周囲温度とガス透過度の関係図からＢ範囲となり、冷凍室蓋体６では、冷凍室空間部１４により高温側の外気温度が約２０℃となり、低温側が−１８℃となるので、周囲温度とガス透過度の関係図からＡ範囲となり、冷蔵室製氷室間仕切体１５では、冷蔵室空間部１１の室温により、高温側の周囲温度が約５℃で、製氷室空間部１２の室温により、低温側が約−１８℃となるので、周囲温度とガス透過度の関係図からＣ範囲となる。 Similarly, in the refrigerating room lid 3, since the outside air temperature on the high temperature side is about 20 ° C. and the low temperature side is about 2 ° C. depending on the room temperature of the refrigerating room space 11, the relationship between the ambient temperature and the gas permeability is B In the ice making chamber lid 4, the outside temperature on the high temperature side is about 20 ° C. and the temperature on the low temperature side is about −18 ° C. depending on the room temperature of the ice making space 12. In the vegetable compartment lid 5, the outdoor air temperature on the high temperature side is about 20 ° C. and the low temperature side is about 5 ° C. depending on the room temperature of the vegetable compartment space portion 13. In the freezer compartment cover 6, the outside air temperature on the high temperature side is about 20 ° C. and the low temperature side is −18 ° C. due to the freezer compartment space portion 14, and therefore the A range from the relationship diagram between the ambient temperature and the gas permeability. In the refrigerator compartment partition 15, depending on the room temperature of the refrigerator compartment 11. At ambient temperature of about 5 ° C. on the high temperature side, the room temperature of the ice making compartment space part 12, since the low temperature side is about -18 ° C., the C range of the relationship diagram of the ambient temperature and gas permeability.
また、製氷室野菜室間仕切体１６では、野菜室空間部１３により高温側の周囲温度が約５℃で、製氷室空間部１２により低温側が約−１８℃となるので、周囲温度とガス透過度の関係図からＣ範囲となり、野菜室冷凍室間仕切体１７では、野菜室空間部１３により高温側の周囲温度が約５℃で、冷凍室空間部１４により低温側が約−１８℃となるので、周囲温度とガス透過度の関係図からＣ範囲となり、冷却室壁体１９では、野菜室空間部１３により高温側の周囲温度が約５℃で、蒸発器９による熱の影響で冷却室空間部１８の室温により、低温側が約−２０℃となるので、周囲温度とガス透過度の関係図からＤ範囲とすることにより、各箇所に応じて、冷蔵庫１を構成している部材の周囲温度から、容易な構成でガス透過度の最適化が図れ安価な断熱構成ができる。 In the ice compartment vegetable compartment partition 16, the ambient temperature on the high temperature side is about 5 ° C. due to the vegetable compartment space 13 and the low temperature side is about −18 ° C. due to the ice compartment space 12. In the vegetable compartment freezer compartment partition 17, the ambient temperature on the high temperature side is about 5 ° C. due to the vegetable compartment space 13 and the low temperature side is about −18 ° C. due to the freezer compartment 14. In the cooling chamber wall 19, the ambient temperature on the high temperature side is about 5 ° C. due to the vegetable chamber space 13, and the cooling chamber space is affected by the heat of the evaporator 9. Since the low temperature side is about −20 ° C. due to the room temperature of 18, by setting the D range from the relationship diagram of the ambient temperature and the gas permeability, the ambient temperature of the members constituting the refrigerator 1 is determined according to each location. Optimize gas permeability with an easy configuration It can cost thermal insulation structure.
以上のように構成された真空断熱筐体について、以下その動作、作用を説明する。 About the vacuum heat insulation housing | casing comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.
冷蔵庫１は、外箱３０をガスバリア部材で形成し、ガスバリア容器３３と密着させることにより、外箱３０側のガスバリア容器３３のガスバリア性を向上できる。 The refrigerator 1 can improve the gas barrier property of the gas barrier container 33 on the outer box 30 side by forming the outer box 30 with a gas barrier member and closely contacting the gas barrier container 33.
外箱３０は高温側であり、周囲環境が高温で、ガスバリア樹脂のガスバリア性が劣化するが、ガスバリア材料からなる外箱３０によりガスバリア性を維持することができるので
、断熱性能が低下することなく真空断熱性能を長期保証できる。さらに、自由に形状を形成できる中空形成による樹脂製のガスバリア容器３３を用いることにより、真空断熱体３２を外箱３０の内壁形状に成形し、真空断熱体３２と外箱３０間の隙間を無くし、空気の対流空間をなくすことにより、断熱性能が向上するとともに、真空断熱体３２と外箱３０を密着させることにより、真空断熱筐体の剛性強度を向上できる。
The outer box 30 is on the high temperature side, and the ambient environment is high, and the gas barrier property of the gas barrier resin is deteriorated. However, since the gas barrier property can be maintained by the outer box 30 made of the gas barrier material, the heat insulation performance is not deteriorated. Long-term guarantee of vacuum insulation performance. Furthermore, by using a resin-made gas barrier container 33 with a hollow shape that can be freely formed, the vacuum heat insulating body 32 is formed into the inner wall shape of the outer box 30, and the gap between the vacuum heat insulating body 32 and the outer box 30 is eliminated. The heat insulation performance is improved by eliminating the convection space of air, and the rigidity and strength of the vacuum heat insulation casing can be improved by bringing the vacuum heat insulator 32 and the outer box 30 into close contact with each other.
また、外箱３０の材質は、例えばアルミ、ステンレス、鉄などのガスバリア性の高い金属板やガラス板で形成することで、ガス透過がなく、ガスバリア容器３３と密着した構成にしているので、周囲環境が高温下でも、ガスバリア容器３３の内部のガスバリア性の劣化を防止し、断熱性能が低下する恐れがないので真空断熱性能を長期保証することができる。 In addition, the outer box 30 is made of a metal plate or glass plate having high gas barrier properties such as aluminum, stainless steel, and iron, so that there is no gas permeation and the gas barrier container 33 is in close contact with the outer box 30. Even in an environment of high temperature, deterioration of the gas barrier property inside the gas barrier container 33 is prevented, and there is no fear that the heat insulation performance is lowered, so that the vacuum heat insulation performance can be ensured for a long time.
また、真空断熱体３２と外箱３０との密着面にガスバリア性の接着部材３１を配置したことにより、外箱３０とガスバリア容器３３との間の隙間を完全に無くすことができ、ガスバリア容器内へのガスの進入を防止できる。さらに、真空断熱体３２を外箱３０内壁形状に成形し、真空断熱体３２と外箱３０間の隙間空間を無くせるので、空気の対流も無くなり、断熱性能が向上できることや、ガスバリア性の接着部材３１の接着強度により、冷蔵庫本体２の真空断熱体３２の剛性強度も向上できる。 Further, by arranging the gas barrier adhesive member 31 on the contact surface between the vacuum heat insulator 32 and the outer box 30, the gap between the outer box 30 and the gas barrier container 33 can be completely eliminated, and the inside of the gas barrier container Gas can be prevented from entering. Furthermore, since the vacuum heat insulating body 32 is formed into the inner wall shape of the outer box 30 and the gap space between the vacuum heat insulating body 32 and the outer box 30 can be eliminated, air convection can be eliminated, heat insulating performance can be improved, and gas barrier adhesive The rigidity strength of the vacuum heat insulating body 32 of the refrigerator main body 2 can be improved by the adhesive strength of the member 31.
また、接着部材３１の材質は、例えば変性ポリエチレン・変性ポリプロピレン等の変性ポリオレフィンなどで、エチレン−ビニルアルコール共重合体などのガスバリア性樹脂や、金属、ガラス、セラミックスなどの基材に強力に接着する特長を持っており、共押出成形によるシート、フィルム、チューブ、ボトルなどの多層成形体を作ることができるので、真空断熱体３２の断熱構成を安易に実現することができる。 The material of the adhesive member 31 is, for example, a modified polyolefin such as modified polyethylene or modified polypropylene, and strongly adheres to a gas barrier resin such as an ethylene-vinyl alcohol copolymer, or a substrate such as metal, glass, or ceramic. Since it has a feature and a multilayer molded body such as a sheet, a film, a tube, and a bottle can be formed by coextrusion molding, the heat insulating configuration of the vacuum heat insulating body 32 can be easily realized.
また、冷蔵庫１を構成している部材の周囲温度から、容易な構成でガス透過度の最適化を図るために、ガスバリア容器の壁構造を変化させても良い。 Further, the wall structure of the gas barrier container may be changed from the ambient temperature of the members constituting the refrigerator 1 in order to optimize the gas permeability with an easy configuration.
例えば、冷蔵庫１を構成している部材の周囲温度と樹脂材料のガス透過度の関係図３により、ＣやＤのなどの低温域で使用される部材では、ガス透過度も低く設定できるので、図５のような単層板材３４などで構成でき、Ｂなどの０℃以上の高温域のみで使用される部材なら、図６のような高温側のガスバリア性のみ向上させるために単層板材３４の外側両面に金属箔などの高バリア層３５の表面処理を施すなどで構成でき、Ａなど低温域から高温域まで使用される部材なら、図７のようなガスバリア性の透過ガス物質別の構成が必要となり、中心より空気バリア層３６、接着層３８、両端に水バリア層３７などの多層で構成でき、Ｅなどの高温域を更に高い領域の場合は、図８のような中心より空気バリア層３６、接着層３８、両端に水バリア層３７、最外両端に金属などの高バリア層３５などの多層で構成できる。 For example, the relationship between the ambient temperature of the members constituting the refrigerator 1 and the gas permeability of the resin material can be set to a low gas permeability in members used in low temperature regions such as C and D, as shown in FIG. In the case of a member that can be composed of a single-layer plate material 34 as shown in FIG. 5 and is used only in a high temperature range of 0 ° C. or higher such as B, the single-layer plate material 34 is used to improve only the high-temperature side gas barrier property as shown in FIG. 7 can be constructed by subjecting both the outer surfaces of the surface to a surface treatment of a high barrier layer 35 such as a metal foil. If the member is used from a low temperature range to a high temperature range, such as A, the configuration according to the permeating gas substance having gas barrier properties as shown in FIG. In the case where the high temperature region such as E is higher, the air barrier layer 36, the adhesive layer 38, and the water barrier layer 37 at both ends from the center. Layer 36, adhesive layer 38, water A layer 37 can be composed of a multilayer such as a high barrier layer 35, such as a metal outermost ends.
よって、単層部材或いは、多層部材或いは、金属箔など高バリア層３５の異材質で形成された積層部材で形成されたことにより、外観形状や内装形状によって自由に形状を変えられ、求める断熱性能を容易に実現することができる。 Therefore, since it is formed of a single layer member, a multilayer member, or a laminated member made of a different material of the high barrier layer 35 such as a metal foil, the shape can be freely changed depending on the appearance shape and interior shape, and the required heat insulation performance Can be easily realized.
また、図５の単層板材３４の材質は、エチレン−ビニルアルコール共重合体や、液晶ポリマー、ポリエチレン、ポリプロピレンなどの空気、水などの高バリア材質とすることにより、安易な材料構成で、ガスバリア容器３３内のガス透過を防止でき、真空度を保つことができるので、断熱性能の低下も防止できる。 Further, the material of the single-layer plate material 34 in FIG. 5 is a gas barrier with an easy material configuration by using a high barrier material such as ethylene-vinyl alcohol copolymer, liquid crystal polymer, polyethylene, polypropylene, etc., air, water, etc. Since the gas permeation in the container 33 can be prevented and the degree of vacuum can be maintained, the heat insulation performance can be prevented from being lowered.
また、図６と図８の高バリア層３５の材質は、熱架橋の少ないアルミ箔、ステンレス箔、金属箔と、ポリプロピレンなどの樹脂材でラミネートされた極薄フィルム板などを熱溶
着する方法や、エチレン−ビニルアルコール共重合体などの有機樹脂層と、無機物質を層状に噴霧した表面処理により、空気や水などのバリア性を向上させることができるので、安価な材料構成で、ガスバリア容器３３内のガス透過を防止でき、真空度を保つことができるので、断熱性能の低下も防止できる。
Further, the material of the high barrier layer 35 in FIGS. 6 and 8 is a method of heat-welding an aluminum foil, a stainless steel foil, a metal foil with little thermal cross-linking and an ultrathin film plate laminated with a resin material such as polypropylene. Since the barrier property such as air or water can be improved by the surface treatment in which an organic resin layer such as ethylene-vinyl alcohol copolymer is sprayed and an inorganic substance is sprayed in layers, the gas barrier container 33 can be formed with an inexpensive material structure. The gas permeation inside can be prevented and the degree of vacuum can be maintained, so that the heat insulation performance can be prevented from being lowered.
また、図７の空気バリア層３６の材質は、エチレン−ビニルアルコール共重合体などとし、水バリア層３７の材質は、ポリエチレン、ポリプロピレンなどとし、接着層３８は、変性ポリエチレン・変性ポリプロピレン等の変性ポリオレフィンなどで形成できるので、使用周囲温度によって、ガスバリア容器３３内のガス透過度の最適化を実現できるバリア構成を容易に確立することができる。 The material of the air barrier layer 36 in FIG. 7 is an ethylene-vinyl alcohol copolymer, the material of the water barrier layer 37 is polyethylene, polypropylene, or the like, and the adhesive layer 38 is a modified polyethylene, modified polypropylene, or the like. Since it can be formed of polyolefin or the like, a barrier configuration capable of realizing optimization of gas permeability in the gas barrier container 33 can be easily established depending on the ambient temperature used.
また、ガスバリア容器の壁構造を外箱側と芯部材側でガスバリア性を変化させ外箱側をガスバリア性が高くなるようにしても良い。 In addition, the gas barrier property of the wall structure of the gas barrier container may be changed between the outer box side and the core member side so that the gas barrier property is increased on the outer box side.
例えば、図９に示すように、冷蔵庫本体２のガスバリア容器３３は、庫外側に高バリア層３５と、空気バリア層３６と、水バリア層３７と、接着層３８を配置した構成とされ、ガスバリア容器３３の材料構成は、高温側であるガス透過度の悪化する外箱側のみ高バリア層３５を配置する構成となり、図１０では、冷蔵庫本体２のガスバリア容器３３は、冷蔵庫１の外箱側に廃材混合層４５と、空気バリア層３６と、水バリア層３７と、接着層３８を配置した構成となり、図１１に示すように、廃材混合層４５は、空気バリア層３６と、水バリア層３７と、接着層３８の廃材から形成した構成としたので、単層板材３４よりもガスバリア性を有し、高温側であるガス透過度の悪化する庫外側のみ廃材混合層４５を配置する構成となり、高温環境下でガスバリア性が劣化する温度依存性のあるガスバリア樹脂の欠点を補え、真空断熱体の性能を維持できるので、断熱性能が低下する恐れがないので真空断熱性能を長期保証できる。 For example, as shown in FIG. 9, the gas barrier container 33 of the refrigerator main body 2 has a configuration in which a high barrier layer 35, an air barrier layer 36, a water barrier layer 37, and an adhesive layer 38 are arranged on the outside of the refrigerator. The material structure of the container 33 is a structure in which the high barrier layer 35 is disposed only on the outer box side where the gas permeability is deteriorated on the high temperature side. In FIG. 10, the gas barrier container 33 of the refrigerator body 2 is the outer box side of the refrigerator 1. The waste material mixed layer 45, the air barrier layer 36, the water barrier layer 37, and the adhesive layer 38 are disposed. As shown in FIG. 11, the waste material mixed layer 45 includes the air barrier layer 36, the water barrier layer, and the water barrier layer. 37 and the waste material of the adhesive layer 38, the waste material mixed layer 45 is disposed only on the outside of the warehouse, which has a gas barrier property than the single-layer plate material 34 and the gas permeability is deteriorated on the high temperature side. , High temperature environment In compensated the disadvantage of the gas barrier resin with a temperature-dependent gas barrier properties is deteriorated, it is possible to maintain the performance of the vacuum heat insulator, can be long-term guarantee vacuum insulation performance since the heat insulating performance is not likely to deteriorate.
また、図１１の廃材混合層４５の材質は、エチレン−ビニルアルコール共重合体や、ポリプロピレンなどで多層混合で形成されているので、熱の流れが、冷蔵庫１の庫外側から庫内側へ熱の移動が迷路のようになり、熱伝達が悪くなるので、ポリエチレン、ポリプロピレンなどの単層で構成している材質よりも、空気や水などのガスバリア性が優位になるため、使用する周囲温度によっては、廃材混合層４５のみで、ガスバリア容器３３を形成することで、設定ガス透過度を確立できる。 Moreover, since the material of the waste material mixing layer 45 in FIG. 11 is formed by multi-layer mixing with an ethylene-vinyl alcohol copolymer, polypropylene, or the like, heat flows from the outside of the refrigerator 1 to the inside of the refrigerator. Since the movement becomes a maze and the heat transfer becomes worse, the gas barrier properties such as air and water are superior to the material composed of single layer such as polyethylene and polypropylene, so depending on the ambient temperature used The set gas permeability can be established by forming the gas barrier container 33 with only the waste material mixed layer 45.
また、芯部材３９は、多孔性構造体で形成され、気泡ウレタンフォームなどを用いたことにより、真空断熱体の内容積を真空引き工程にて確実に所定の設定真空度に到達するので、求める真空断熱性能を実現することができる。 Further, the core member 39 is formed of a porous structure, and by using a cellular urethane foam or the like, the internal volume of the vacuum heat insulator can be surely reached a predetermined set vacuum degree in the evacuation step. Vacuum insulation performance can be realized.

図１５と図１６において、冷蔵庫の製氷室蓋体４は、外箱部材４ａ、接着部材４ｂ、真空断熱体２０、内箱部材４ｃを重ねて配置した構成とし、真空断熱体２０はガスバリア容器２０ａの内部に芯部材２０ｂと吸着部材２０ｃを配置した構成としている。ガスバリア容器２０ａは中空成形（ブロー成形）によりガスバリア樹脂を加工したものであり、形状を自由に形成でき、外箱部材４ａや内箱部材４ｃの内壁形状に成形する。芯部材２０ｂは多孔性構造体で形成され、気泡ウレタンフォームなどを用いている。気泡ウレタンフォームは連続気泡ウレタンフォームでも独立気泡ウレタンフォームでもよく、真空引きの効率を重視する場合は連続気泡ウレタンフォームなどを使用する方がよい。 15 and 16, the ice making chamber lid 4 of the refrigerator has a configuration in which an outer box member 4a, an adhesive member 4b, a vacuum heat insulator 20, and an inner box member 4c are arranged so as to overlap each other, and the vacuum heat insulator 20 is a gas barrier container 20a. It is set as the structure which has arrange | positioned the core member 20b and the adsorption | suction member 20c inside. The gas barrier container 20a is obtained by processing a gas barrier resin by hollow molding (blow molding), can be freely formed in shape, and is molded into the inner wall shape of the outer box member 4a or the inner box member 4c. The core member 20b is formed of a porous structure and uses cellular urethane foam or the like. The cellular urethane foam may be an open-celled urethane foam or a closed-celled urethane foam. If importance is placed on the efficiency of vacuuming, it is better to use an open-celled urethane foam.
図１７〜図２２において、冷蔵庫の製氷室蓋体４の真空断熱体２０は、ガスバリア容器２０ａの内部に芯部材２０ｂと吸着部材２０ｃを配置し、ガスバリア容器２０ａにはウレタン充填用兼真空引き用の真空穴２０ｄ、真空引き後、真空穴２０ｄを封止する真空穴封止部材２０ｅ、ウレタン充填時の空気逃穴２０ｆ、空気逃穴封止部材２０ｇを配置した構成としている。真空穴２０ｄと真空穴封止部材２０ｅは、低温側となる内箱部材側に配置している。なお、空気逃穴２０ｆは中空成形時の空気注入口を利用している。 17 to 22, the vacuum heat insulator 20 of the ice making chamber lid 4 of the refrigerator has a core member 20b and an adsorbing member 20c arranged inside the gas barrier container 20a, and the gas barrier container 20a is used for filling and evacuating urethane. The vacuum hole 20d, a vacuum hole sealing member 20e for sealing the vacuum hole 20d after evacuation, an air escape hole 20f at the time of urethane filling, and an air escape hole sealing member 20g are arranged. The vacuum hole 20d and the vacuum hole sealing member 20e are arranged on the inner box member side which is the low temperature side. The air escape hole 20f uses an air inlet at the time of hollow molding.
以上のように構成された真空断熱筐体について、以下その動作、作用を説明する。 About the vacuum heat insulation housing | casing comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.
冷蔵庫の製氷室蓋体４は、外観を形成する外箱部材４ａと、接着部材４ｂと、内箱部材４ｃと、真空断熱体２０と、ガスケット２１と、フレーム２２と、フレーム止めネジ２３を配置した構成により、内箱部材４ｃにフレーム２２をフレーム止めネジ２３で固定することで、引き出し扉を構成することができる。フレーム止めネジ２３は内箱部材４ｃを貫通することなく、真空断熱体２０を破損することはない。 The ice making chamber lid 4 of the refrigerator has an outer box member 4a, an adhesive member 4b, an inner box member 4c, a vacuum heat insulator 20, a gasket 21, a frame 22, and a frame set screw 23 that form an appearance. With the configuration described above, the drawer door can be configured by fixing the frame 22 to the inner box member 4c with the frame fixing screw 23. The frame fixing screw 23 does not penetrate the inner box member 4c and does not damage the vacuum heat insulating body 20.
冷蔵庫の製氷室蓋体４は、外箱部材４ａをガスバリア部材で形成し、ガスバリア容器２０ａと密着させることにより、外箱部材４ａ側のガスバリア容器２０ａのガスバリア性を向上できる。 The ice making chamber lid 4 of the refrigerator can improve the gas barrier property of the gas barrier container 20a on the outer box member 4a side by forming the outer box member 4a with a gas barrier member and closely contacting the gas barrier container 20a.
外箱部材４ａは高温側であり、周囲環境が高温で、ガスバリア樹脂のガスバリア性が劣化するが、ガスバリア材料からなる外箱部材４ａによりガスバリア性を維持することができるので、断熱性能が低下することなく真空断熱性能を長期保証できる。さらに、自由に形状を形成できる中空形成による樹脂製のガスバリア容器２０ａを用いることにより、真空断熱体２０を外箱部材４ａの内壁形状に成形し、真空断熱体２０と外箱部材４ａ間の隙間を無くし、空気の対流空間をなくすことにより、断熱性能が向上するとともに、真空断熱体２０と外箱部材４ａを密着させることにより、真空断熱筐体の剛性強度を向上できる。 The outer box member 4a is on the high temperature side, and the ambient environment is high, and the gas barrier property of the gas barrier resin is deteriorated. However, since the gas barrier property can be maintained by the outer box member 4a made of the gas barrier material, the heat insulating performance is lowered. Long-term guarantee of vacuum insulation performance without any problems. Further, by using a resin-made gas barrier container 20a having a hollow shape that can be freely formed, the vacuum heat insulating body 20 is formed into the inner wall shape of the outer box member 4a, and the gap between the vacuum heat insulating body 20 and the outer box member 4a is formed. The heat insulation performance is improved by eliminating the air convection space, and the rigidity of the vacuum heat insulation housing can be improved by bringing the vacuum heat insulator 20 and the outer box member 4a into close contact with each other.
また、外箱部材４ａの材質は、ガラスやアルミ、ステンレス、鉄などのガスバリア性の高い金属板で形成することで、ガス透過がなく、ガスバリア容器２０ａと密着した構成にしているので、周囲環境が高温下でも、ガスバリア容器２０ａの内部のガスバリア性の劣化を防止し、断熱性能が低下する恐れがないので真空断熱性能を長期保証することができる。 Further, the material of the outer box member 4a is made of a metal plate having a high gas barrier property such as glass, aluminum, stainless steel, iron, etc., so that there is no gas permeation and is in close contact with the gas barrier container 20a. However, even under high temperatures, the deterioration of the gas barrier property inside the gas barrier container 20a can be prevented and the heat insulation performance can be prevented from being lowered, so that the vacuum heat insulation performance can be ensured for a long time.
また、真空断熱体２０と外箱部材４ａとの密着面にガスバリア性の接着部材４ｂを配置したことにより、外箱３０とガスバリア容器３３との間の隙間を完全に無くすことができ
、ガスバリア容器内へのガスの進入を防止できる。さらに、真空断熱体２０を外箱部材４ａ内壁形状に成形し、真空断熱体２０と外箱部材４ａ間の隙間空間を無くせるので、空気の対流も無くなり、断熱性能が向上できることや、ガスバリア性の接着部材４ｂの接着強度により、製氷室蓋体４の剛性強度も向上できる。
Further, by arranging the gas barrier adhesive member 4b on the contact surface between the vacuum heat insulator 20 and the outer box member 4a, the gap between the outer box 30 and the gas barrier container 33 can be completely eliminated, and the gas barrier container The gas can be prevented from entering the inside. Furthermore, since the vacuum heat insulating body 20 is formed into the inner wall shape of the outer box member 4a and the gap space between the vacuum heat insulating body 20 and the outer box member 4a can be eliminated, air convection can be eliminated, heat insulating performance can be improved, and gas barrier properties Due to the adhesive strength of the adhesive member 4b, the rigidity strength of the ice making chamber lid 4 can be improved.
また、図１６において、真空断熱体２０は外箱部材側の厚みＴ１と内箱部材側の厚みＴ２を同じにして、外箱部材側の厚みＴ１の材質を内箱部材側の厚みＴ２の材質よりガスバリア製の高い材質にしても良い。高温側である外箱部材側の厚みＴ１のガスバリア性を高くすることでガスバリア性が向上し、高温環境下でガスバリア性が劣化する温度依存性のあるガスバリア樹脂材料の欠点を補え、真空断熱体２０の性能を維持できる。 Further, in FIG. 16, the vacuum heat insulator 20 has the same thickness T1 on the outer box member side and the same thickness T2 on the inner box member side, and the material of the thickness T1 on the outer box member side is the material of the thickness T2 on the inner box member side. A higher gas barrier material may be used. Increased gas barrier property of thickness T1 on the outer box member side, which is the high temperature side, improves the gas barrier property, and compensates for the disadvantages of the temperature-dependent gas barrier resin material that degrades the gas barrier property in a high temperature environment. 20 performances can be maintained.
また、図１６において、真空断熱体２０は外箱部材側の厚みＴ１を内箱部材側の厚みＴ２より厚くしても良い。高温側である外箱部材側の厚みＴ１を厚くすることでガスバリア性が向上し、高温環境下でガスバリア性が劣化する温度依存性のあるガスバリア樹脂材料の欠点を補え、真空断熱体２０の性能を維持できる。なお、上記厚みと材質は断熱性能とコストを考慮して最適になるように適宜決めれば良いものである。 Moreover, in FIG. 16, the vacuum heat insulating body 20 may make the thickness T1 on the outer box member side thicker than the thickness T2 on the inner box member side. By increasing the thickness T1 on the outer box member side, which is the high temperature side, the gas barrier property is improved, and the disadvantage of the temperature-dependent gas barrier resin material that deteriorates the gas barrier property in a high temperature environment is compensated for. Can be maintained. The thickness and material may be determined appropriately so as to be optimal in consideration of heat insulation performance and cost.
また、真空断熱体２０は、ガスバリア容器２０ａの真空引き時の封止口の真空穴２０ｄと真空穴封止部材２０ｅは、低温側となる内箱側に配置したことで、封止部分のガスバリア樹脂のガスバリア性が向上し、構造的にガスバリア性が悪い封止口のガスバリア性を向上でき設定真空度に保たれ、断熱性能が低下する恐れがないので真空断熱性能を長期保証できる。 Further, the vacuum heat insulator 20 has the gas hole 20d and the vacuum hole sealing member 20e of the sealing port at the time of evacuating the gas barrier container 20a disposed on the inner box side which is the low temperature side. The gas barrier property of the resin is improved, the gas barrier property of the sealing port having a structurally poor gas barrier property can be improved, the set vacuum degree is maintained, and the heat insulation performance is not deteriorated, so that the vacuum heat insulation performance can be guaranteed for a long time.
また、真空断熱体２０は、形状の難易度や、使用箇所や使用環境によって、ガスバリア容器２０ａの厚みや材質などの断熱構成を選択して構成することにより、外観形状や内装形状によって自由に形状を変えられ、求める断熱性能を安易に実現することができる。 Moreover, the vacuum heat insulating body 20 can be freely shaped according to the external shape and the interior shape by selecting and configuring the heat insulation configuration such as the thickness and material of the gas barrier container 20a depending on the difficulty of the shape, the use location and the use environment. The required heat insulation performance can be easily realized.
また、芯部材２０ｂは、多孔性構造体で形成され、気泡ウレタンフォームなどを用いたことにより、真空断熱体２０の内容積を真空引き工程にて確実に所定の設定真空度に到達できるので、求める真空断熱性能を実現することができる。 Further, the core member 20b is formed of a porous structure, and by using cellular urethane foam or the like, the internal volume of the vacuum heat insulating body 20 can surely reach a predetermined set degree of vacuum in the evacuation step. The required vacuum insulation performance can be realized.
また、芯部材２０ｂの材質は、グラスウールなどと混合させることで、真空断熱体２０の内容積の空隙率は向上し、真空引き工程にて、所定の設定真空度に到達する時間を短縮することができる。 Further, the material of the core member 20b is mixed with glass wool or the like, so that the void ratio of the internal volume of the vacuum heat insulating body 20 is improved, and the time to reach a predetermined set vacuum degree is shortened in the evacuation process. Can do.
また、ガスバリア容器２０ａの中空成形加工時の空気挿入口をウレタン発泡充填時の空気抜き口の空気逃穴２０ｆとしたことにより、真空断熱体２０の内容積をウレタン発泡工程にて確実に所定の設定充填量に到達するので、求める真空断熱性能を実現することができる。 Further, the air insertion port at the time of hollow molding of the gas barrier container 20a is the air escape hole 20f of the air vent at the time of urethane foam filling, so that the internal volume of the vacuum heat insulating body 20 is reliably set to a predetermined value in the urethane foaming process. Since the filling amount is reached, the required vacuum insulation performance can be realized.
また、ガスバリア容器２０ａ内に吸着部材２０ｃを内設することにより、ガスバリア容器２０ａの内部の空気、水などの発生ガスを吸着できるので、設定真空度は長期に保たれるので、長期信頼性を保証した断熱性能を実現することができる。 In addition, by providing the adsorbing member 20c in the gas barrier container 20a, the generated gas such as air and water inside the gas barrier container 20a can be adsorbed, so that the set vacuum can be maintained for a long period of time. Guaranteed thermal insulation performance can be achieved.
また、真空穴封止部材２０ｅと、空気逃穴封止部材２０ｇの材質を、ガスバリア容器２０ａの外層材料と同材質をラミネートしたアルミ箔樹脂ラミネートフィルムにて、真空穴２０ｄと、空気逃穴２０ｆを加熱溶着して密閉しているので、ガスバリア容器２０ａ内の設定真空度は保たれるので、長期信頼性を保証した断熱性能を実現することができる。 The vacuum hole sealing member 20e and the air escape hole sealing member 20g are made of an aluminum foil resin laminate film obtained by laminating the same material as the outer layer material of the gas barrier container 20a. Since the set vacuum degree in the gas barrier container 20a is maintained, the heat insulation performance guaranteeing long-term reliability can be realized.
