Description
本実施形態は、真空断熱パネル、真空断熱パネルの製造方法及び真空断熱パネルを備えた冷蔵庫に関する。 The present embodiment relates to a vacuum insulation panel, a method of manufacturing the vacuum insulation panel, and a refrigerator including the vacuum insulation panel.
従来より、冷蔵庫は、外箱と内箱との間に発泡断熱材を充填した断熱箱体により構成され、その断熱箱体の内部に貯蔵室を形成しているが、更なる断熱性能を向上させて消費電力量を低減させたり、あるいは、断熱箱体の壁厚を薄くして庫内容積効率を向上させるため、外箱と内箱との間に充填する発泡断熱材の一部に換えて真空断熱パネルが設けられている。 Conventionally, a refrigerator is constituted by a heat insulation box filled with a foam insulation material between an outer case and an inner case, and a storage room is formed inside the heat insulation box, but the heat insulation performance is further improved To reduce power consumption, or to reduce the wall thickness of the heat insulation box to improve the interior volume efficiency, change to a part of the foam insulation to be filled between the outer case and the inner case A vacuum insulation panel is provided.
この種の真空断熱パネルは、例えば特許文献１に示すように、芯材と外包材とを備えている。芯材は、細いガラス繊維の綿状物であるグラスウールなどから形成され、外包材は、アルミ箔などを有するラミネートフィルムの袋などで形成されている。この真空断熱パネルは、芯材を外包材に収容し、外包材内を減圧し開口を閉塞し、外包材内を減圧状態に保持して構成されている。 For example, as shown in Patent Document 1, this type of vacuum heat insulation panel includes a core material and an outer packaging material. The core material is formed of glass wool or the like which is a cotton-like material of thin glass fibers, and the outer packaging material is formed of a laminated film bag having aluminum foil or the like. The vacuum heat insulation panel is configured such that the core material is accommodated in the outer packaging material, the inside of the outer packaging material is decompressed to close the opening, and the inside of the outer packaging material is maintained in a decompressed state.
しかしながら、真空断熱パネルは、パネル製造時やキャビネットへの組み込み時に袋体の外包材が損傷してしまうと、外部の空気が外包材の内部に入り込み、断熱性能が著しく悪化する。特に、外包材の損傷によって微細な孔が生じると、その孔が数μｍを下回る程度の微細な孔であっても、外部の空気や水分が外包材の内部へ入り込む。外包材に生じた孔の大きさにもよるが例えば数十日から数年程度の長い時間をかけて徐々に真空断熱パネルの断熱性能が悪化するスローリークが発生し、最終的に外包材の内部が大気圧になって断熱性能が著しく悪化する。そのため、真空断熱パネルの製造時に十分な断熱性能が確認されても、その後、徐々に断熱性能が悪化することから、長期間にわたる断熱性能の信頼性確保が難しいという事情がある。 However, in the vacuum insulation panel, if the outer packaging material of the bag body is damaged at the time of manufacturing the panel or incorporating it in a cabinet, the external air gets into the inside of the outer packaging material and the thermal insulation performance is significantly deteriorated. In particular, when fine pores are generated due to damage to the outer packaging material, external air and moisture enter the inside of the outer packaging material even if the pores are fine pores having a size of less than several μm. Depending on the size of the holes formed in the outer packaging material, a slow leak occurs, which gradually deteriorates the thermal insulation performance of the vacuum insulation panel over a long period of, for example, several tens of days to several years. The inside becomes atmospheric pressure, and the heat insulation performance is significantly deteriorated. Therefore, even if a sufficient heat insulation performance is confirmed at the time of manufacturing the vacuum heat insulation panel, the heat insulation performance is gradually deteriorated thereafter, and there is a problem that it is difficult to ensure the reliability of the heat insulation performance over a long period.
これに対して、酸化カルシウム（ＣａＯ）等のような外包材の内部に入り込んだ水を吸着する吸着材を芯材に混合することも考えられるが、コストが増大するとともに吸着材の使用量に限界がある。 On the other hand, it is conceivable to mix an adsorbent which adsorbs water which has entered the inside of the outer packaging material such as calcium oxide (CaO) into the core material, but the cost increases and the amount of the adsorbent used There is a limit.
そこで、長期間にわたって断熱性能を維持することができる真空断熱パネルを用いた冷蔵庫を提供することを目的とする。 Then, it aims at providing the refrigerator using a vacuum insulation panel which can maintain insulation performance over a long period of time.
本実施形態に係る真空断熱パネルは、袋状をなし内部が減圧されている外包材と、前記外包材に収容され断熱性を有する芯材と、前記外包材内の水を吸着する吸着材と備えた真空断熱パネルにおいて、前記吸着材が前記芯材に直接付与されたヒドロキシル基であるものである。
また、本実施形態に係る真空断熱パネルの製造方法は、袋状をなし内部が減圧されている外包材と、前記外包材に収容され断熱性を有する芯材と、前記外包材内の水を吸着する吸着材と備えた真空断熱パネルの製造方法において、前記芯材にヒドロキシル基を直接付与する処理を行い、前記吸着材として前記ヒドロキシル基を前記芯材に設ける方法である。
The vacuum insulation panel according to the present embodiment has an outer packaging material which has a bag-like shape and is internally depressurized, a core material contained in the outer packaging material and having heat insulation, and an adsorbent for adsorbing water in the outer packaging material. The vacuum heat insulation panel provided WHEREIN: The said adsorption material is a hydroxyl group directly provided to the said core material.

以下、図面に基づいて本発明の一実施形態について説明する。 Hereinafter, an embodiment of the present invention will be described based on the drawings.
本実施形態の冷蔵庫１０は、図１に示すように、鋼板からなる外箱１２と、外箱１２の内部に収納され貯蔵空間を形成する内箱１４との間に断熱空間を設けた冷蔵庫１０の外郭をなすキャビネット１８を備え、このキャビネット１８に不図示の冷凍サイクルなどを組み込んで構成されている。 The refrigerator 10 of the present embodiment is, as shown in FIG. 1, a refrigerator 10 in which a heat insulating space is provided between an outer case 12 made of a steel plate and an inner case 14 housed inside the outer case 12 to form a storage space. The cabinet 18 is formed by incorporating a refrigeration cycle (not shown) into the cabinet 18.
断熱空間を形成する外箱１２や内箱１４の断熱空間側には、真空断熱パネル５０が折り曲げられることなく、外箱１２や内箱１４に沿ってほぼ平面状になるようにホットメルトなどの接着剤によって貼り付けられている。なお、ここでいうホットメルトには熱可塑性樹脂のみを使用する接着剤だけでなく、熱可塑性樹脂に熱硬化性樹脂を混ぜて使用する接着剤も含む。また、キャビネット１８は、断熱空間で真空断熱パネル５０以外のところに隙間が生じることがある。この隙間には、必要に応じて、ウレタンフォームなどからなる発泡断熱材２０や、冷凍サイクルの一部を構成する放熱パイプなどの冷媒パイプが配設され、外箱１２及び内箱１４が一体化される。特に、放熱パイプなどの冷媒パイプの一部は真空断熱パネル５０の外箱１２側に凹溝を形成し、その凹溝に冷媒パイプを収納することで配置する。そのため、冷蔵庫１０の背面や側面に配した真空断熱パネル５０においては、冷媒パイプと真空断熱パネル５０とが接触する構成となる。 In the heat insulation space side of the outer case 12 and the inner case 14 which form the heat insulation space, the vacuum heat insulation panel 50 is not bent but is generally flat along the outer case 12 and the inner case 14. It is stuck by an adhesive. In addition, the hot melt referred to here includes not only an adhesive using only a thermoplastic resin but also an adhesive using a thermoplastic resin mixed with a thermosetting resin. Moreover, the cabinet 18 may produce a clearance in places other than the vacuum heat insulation panel 50 in heat insulation space. In this gap, if necessary, a foam heat insulating material 20 made of urethane foam or the like, or a refrigerant pipe such as a heat radiation pipe that constitutes a part of the refrigeration cycle are disposed, and the outer case 12 and the inner case 14 are integrated. Be done. In particular, a part of the refrigerant pipe such as the heat release pipe is formed by forming a recessed groove on the outer case 12 side of the vacuum heat insulation panel 50, and storing the refrigerant pipe in the recessed groove. Therefore, in the vacuum insulation panel 50 disposed on the back and side of the refrigerator 10, the refrigerant pipe and the vacuum insulation panel 50 are in contact with each other.
キャビネット１１の内部に設けられた貯蔵空間は、断熱仕切壁２２によって上方の冷蔵空間と下方の冷凍空間とに区画されている。冷蔵空間は、さらに仕切壁２４によって上下に区画され、上部空間に複数段の載置棚を設けた冷蔵室２６が設けられ、下部空間に引き出し式の収納容器を配置する野菜室２８が設けられている。冷凍空間には、比較的小容積の自動製氷機を備えた製氷室３０と小型冷凍室３２を左右に併設しており、その下方には冷凍室３４が設けられている。 The storage space provided inside the cabinet 11 is divided by the heat insulation partition wall 22 into an upper refrigeration space and a lower refrigeration space. The refrigerated space is further divided up and down by a partition wall 24. A refrigerated room 26 provided with a plurality of stages of mounting shelves is provided in the upper space, and a vegetable room 28 in which a drawer type storage container is disposed in the lower space. ing. In the freezing space, an ice making chamber 30 equipped with an automatic ice making machine with a relatively small volume and a small freezing chamber 32 are provided side by side, and a freezing chamber 34 is provided below it.
図２に真空断熱パネル５０の端部の断面を示すが、真空断熱パネル５０は、取付けられる壁部の形状に合わせて成形された矩形板状の芯材５２と、芯材５２を収容する外包材５４とを備える。なお、真空断熱パネルの形状は矩形板状に限られず、矩形の角部を面取りした多角形状や、部位によって厚みの異なる段差形状など自由な形状のパネルを使用可能である。 FIG. 2 shows a cross section of an end portion of the vacuum heat insulation panel 50, but the vacuum heat insulation panel 50 has a rectangular plate-like core 52 molded according to the shape of the wall to be attached and an outer package for containing the core 52 And the material 54. In addition, the shape of a vacuum heat insulation panel is not restricted to a rectangular plate shape, The panel of free shapes, such as a polygonal shape which chamfered the rectangular corner, a level | step difference shape which differs in thickness by site | part, is possible.
芯材５２は、断熱性の高い材料からなる積層材５２ａを、例えばポリエチレンなどの合成樹脂フィルムからなる内袋５２ｂに収納した後、矩形板状に圧縮硬化されて成形されたものである。この例では、積層材５２ａは、グラスウールやシリカアルミナなどの無機繊維をシート状に成形した無機繊維シート５２ａ１を複数枚積層してなる。 The core 52 is formed by compressing and curing a laminated material 52a made of a material having high thermal insulation in an inner bag 52b made of a synthetic resin film such as polyethylene, for example, into a rectangular plate shape. In this example, the laminated material 52a is formed by laminating a plurality of inorganic fiber sheets 52a1 formed by molding inorganic fibers such as glass wool and silica alumina into a sheet.
なお、内袋５２ｂを使用せずに芯材５２を構成してもよい。すなわち、積層材５２ａを内袋５２ｂに収納せず、直接、外包材５４の内部に収納する。この外包材５４に積層材５２ａを収納した状態で内部を減圧して真空状態にすることで、積層材真空断熱パネル５０を構成する。 The core 52 may be configured without using the inner bag 52b. That is, the laminated material 52a is directly accommodated inside the outer packaging material 54 without being accommodated in the inner bag 52b. The laminated material vacuum insulation panel 50 is configured by reducing the pressure inside the outer packaging material 54 in a state in which the laminated material 52a is housed in the outer packaging material 54 and bringing the interior into a vacuum state.
無機繊維シート５２ａ１には、バーナ等から噴射した炎を無機繊維シート５２ａ１の表面に吹きかけてヒドロキシル基を付与する火炎処理が施されている。なお、積層材５２ａを構成する無機繊維シート５２ａ１にヒドロキシル基を付与する処理として、上記の火炎処理以外にも、例えば、プラズマ処理、コロナ処理、あるいは水酸化ナトリウム水溶液の含浸処理であってもよい。 The inorganic fiber sheet 52a1 is subjected to a flame treatment in which a flame injected from a burner or the like is blown to the surface of the inorganic fiber sheet 52a1 to provide a hydroxyl group. In addition to the above-described flame treatment, for example, plasma treatment, corona treatment, or impregnation treatment with an aqueous solution of sodium hydroxide may be used as treatment to provide a hydroxyl group to the inorganic fiber sheet 52a1 constituting the laminated material 52a. .
また、積層材５２ａは、これを構成する全ての無機繊維シート５２ａ１に上記のようなヒドロキシル基を付与する処理を施してもよく、また、ヒドロキシル基を付与する処理を施した無機繊維シート５２ａ１とヒドロキシル基を付与する処理を施す前の無機繊維シート５２ａ１とを混合して積層してもよい。ヒドロキシル基を付与する処理を施した無機繊維シート５２ａ１とヒドロキシル基を付与する処理を施す前の無機繊維シート５２ａ１とを混合すことにより、長期間にわたって高い断熱性能を確保することができる真空断熱パネルをコスト安価に製造することができる。 In addition, the laminated material 52a may be subjected to the treatment to impart hydroxyl groups as described above to all of the inorganic fiber sheets 52a1 constituting the laminate material 52, and the inorganic fiber sheets 52a1 subjected to the treatment to impart hydroxyl groups You may mix and laminate the inorganic fiber sheet 52a1 before giving the process which provides a hydroxyl group. A vacuum thermal insulation panel capable of securing high heat insulation performance over a long period of time by mixing an inorganic fiber sheet 52a1 treated to give a hydroxyl group and an inorganic fiber sheet 52a1 before subjected to a treatment to give a hydroxyl group The cost can be manufactured inexpensively.
外包材５４は、外側から内側に向かって表面保護層５４ａとガスバリア層５４ｂと熱溶着層５４ｃとが順に積層された３層構造の積層フィルムを備える。表面保護層５４ａは、例えばポリエチレンテレフタラートなどの比較的熱に強い合成樹脂から構成されている。ガスバリア層５４ｂは、金属蒸着物（例えばアルミを樹脂フィルム上に蒸着したアルミ蒸着物）、または金属箔（例えばアルミ箔）で形成されている。熱溶着層５４ｃは例えば高密度ポリエチレン等の熱溶着性を有する合成樹脂から構成されている。 The outer packaging material 54 includes a laminated film of a three-layer structure in which a surface protective layer 54a, a gas barrier layer 54b, and a heat welding layer 54c are laminated in order from the outside to the inside. The surface protective layer 54a is made of, for example, a relatively heat-resistant synthetic resin such as polyethylene terephthalate. The gas barrier layer 54 b is formed of a metal deposition (for example, an aluminum deposition in which aluminum is deposited on a resin film) or a metal foil (for example, an aluminum foil). The heat welding layer 54c is made of, for example, a synthetic resin having heat welding properties such as high density polyethylene.
外包材５４は、２枚の積層フィルムの熱溶着層５４ｃを対向して重ね合わせ、周囲部を加圧及び加熱することで、２枚の積層フィルムが熱溶着され密封することにより開口部を有する袋状に形成されている。外包材５４は、開口部から芯材５２を内部に収容した後、内部が真空排気され減圧された状態で外包材５４の開口部が熱溶着により密閉されている。 The outer wrapping material 54 has an opening by heat welding and sealing the two laminated films by facing and laminating the heat welding layers 54c of the two laminated films and pressing and heating the periphery. It is formed in the shape of a bag. The outer packaging material 54 accommodates the core 52 inside through the opening, and the opening of the outer packaging material 54 is sealed by heat welding in a state where the inside is evacuated and decompressed.
外包材５４の周縁部は、２枚の積層フィルムを熱溶着するために芯材５２から周囲にはみ出しており、このはみ出した部分が芯材５２の縁部において折り曲げられ、一方の積層フィルムに重ね合わせた折返し部６２をなしている。 The peripheral portion of the outer packaging material 54 protrudes from the core 52 to the periphery in order to thermally weld the two laminated films, and the protruding part is bent at the edge of the core 52, and is stacked on one laminated film. A folded back portion 62 is formed.
以上のような本実施形態の冷蔵庫１０では、外包材５４に収容された芯材５２を構成する無機繊維シート５２ａ１に対してヒドロキシル基を付与する処理が施されているため、外包材５４の内部へ入り込んだ外部の水分を無機繊維シート５２ａ１が吸着して、長期間にわたって高い断熱性能を確保することができる。 In the refrigerator 10 according to the present embodiment as described above, the treatment for giving a hydroxyl group is performed on the inorganic fiber sheet 52a1 constituting the core material 52 contained in the outer packaging material 54, so the inside of the outer packaging material 54 The inorganic fiber sheet 52a1 adsorbs the external moisture that has entered the space, and high heat insulation performance can be ensured over a long period of time.
また、本実施形態では、シート状の無機繊維シート５２ａの表面にヒドロキシル基を付与する処理を施し、これを複数枚積層して芯材５２を形成しているため、芯材５２の内部まで均一にヒドロキシル基を付与することができ、外包材５４の内部へ入り込んだ水分の吸着能力を大幅に向上することができる。 Further, in the present embodiment, the surface of the sheet-like inorganic fiber sheet 52a is subjected to a treatment for giving a hydroxyl group, and a plurality of sheets are laminated to form the core 52, so that the inside of the core 52 is uniform. Hydroxyl groups can be added to the outer packaging material 54, and the adsorption capacity of water entering the inside of the outer packaging material 54 can be greatly improved.
なお、芯材５２の全体にわたってヒドロキシル基を付与する処理を施すことが好ましいが、芯材５２の一部だけにヒドロキシル基を付与する処理を施してもよい。すなわち、例えば火炎処理によりヒドロキシル基を付与する場合、無機積層シート５２ａの表面の繊維のみに火炎処理が施された状態の無機繊維シート５２ａを積層して芯材５２を構成してもよい。 In addition, although it is preferable to perform the process which provides a hydroxyl group over the whole core material 52, you may perform the process which provides a hydroxyl group only to a part of core material 52. FIG. That is, for example, in the case of providing a hydroxyl group by flame treatment, the core material 52 may be configured by laminating the inorganic fiber sheet 52 a in a state in which flame treatment is performed only on the fibers of the surface of the inorganic laminate sheet 52 a.
