There are a free-range open-type refrigerator compartment door (2), a drawer-type ice making door (3), a vegetable compartment door (4), and a freezer compartment door (5).
[0008] 図 2は、その中のひとつである冷蔵室扉(2)の A— A線に沿った横断面図であり、 扉の外郭を形成する箱状の外板 (6)と、シールガスケットの装着部(8)を形成した内 板 (7)とを結合し、それらの内面の空間部に発泡断熱材 (9)を充填して一体ィ匕したも のである。 [0008] Fig. 2 is a cross-sectional view taken along line A—A of the refrigerator compartment door (2), one of which is a box-shaped outer plate (6) that forms the outer shell of the door, and a seal The inner plate (7) on which the gasket mounting portion (8) is formed is joined, and the space on the inner surface thereof is filled with the foam insulation (9) and integrated together.
[0009] しかして、前記外板 (6)は、その外表面に透明体力もなる外面シート(10)を配して おり、下層部に位置するフィルムシート(12)に印刷された加飾印刷層(11)が視認で きるように一体に形成されて 、る。 [0009] Therefore, the outer plate (6) is provided with an outer surface sheet (10) having a transparent physical strength on the outer surface, and decorative printing printed on the film sheet (12) located in the lower layer portion. The layer (11) is integrally formed so that it can be seen.
[0010] 図 3に外板 (6)部分の詳細断面を示すように、前記外面シート(10)は、 l〜3mm厚 の透明アクリル榭脂シートで形成されており、フィルムシート(12)は 200 μ m厚のポリ プロピレン榭脂フィルムで形成され、その表面に絵柄や模様、あるいは文字などの加 飾印刷(11)を施し、これをバインダー(13)を介して外面シート(10)に接着して一体 化している。 [0010] As shown in FIG. 3 which shows a detailed cross section of the outer plate (6), the outer sheet (10) is formed of a transparent acrylic resin sheet having a thickness of 1 to 3 mm, and the film sheet (12) is It is made of a 200 μm thick polypropylene resin film, and its surface is decorated with decorative prints (11) such as patterns, patterns, or letters, and is bonded to the outer sheet (10) via a binder (13). And integrated.
[0011] 前記加飾印刷された層 (11)のフィルムシート(12)側には、不透明層(14)を設けて おり、さらに、フィルムシート(12)の下面には発泡断熱材(9)との密着性を大きくする
ためにバインダー層(15)を設け、これらを一体化して積層体としたシートを真空成形 することで外板 (6)を形成して!/、る。 [0011] An opaque layer (14) is provided on the film sheet (12) side of the decorative printed layer (11), and a foam insulation (9) is provided on the lower surface of the film sheet (12). Increase adhesion with For this purpose, a binder layer (15) is provided, and the outer plate (6) is formed by vacuum forming a sheet that is formed by integrating these layers! /
[0012] 外面シート(10)は、前記説明においては、アクリル榭脂としたが、これに限らず透明 性を有する熱可塑性榭脂であればよぐ例えば、ポリカーボネート (PC)榭脂、ポリス チレン (PS)榭脂、ポリプロピレン (PP)榭脂ゃ AS榭脂、 ABS榭脂などでもよい。この 他、ポリ乳酸 (PLA)ベースの榭脂を用いることも可能であり、特に、 PLA榭脂とアタリ ル榭脂とを混合 (ァロイ)した榭脂シートを用いてもょ 、。 [0012] The outer sheet (10) is acrylic resin in the above description, but is not limited to this, and any thermoplastic resin having transparency may be used. For example, polycarbonate (PC) resin, polystyrene (PS) resin, polypropylene (PP) resin may be AS resin, ABS resin, etc. In addition, it is also possible to use polylactic acid (PLA) -based resin, and in particular, use a resin sheet in which PLA resin and talyl resin are mixed (alloyed).

In addition, the use of PLA resin can suppress the production amount of carbon dioxide in the natural world, so that a product with less environmental pollution can be provided.
[0014] また、外面シート (10)については、上記の他、表面側に透明アクリル榭脂、裏面側 に透明 ABS榭脂を設けてこれらを張り合わせたシートを用いてもよぐこのように構成 することで、耐衝撃性にやや劣るアクリル榭脂シートと、表面性がやや劣り、屈折率の 関係から高級感にやや欠ける ABS榭脂シートのそれぞれの欠点を補い、双方の長 所を併せ持つシートを得ることができる。また、シート表面にハードコート処理を施せ ば、傷つきを抑制することができ、高級感を長期に亙って保持することができる。さら に裏面のフィルムシート(12)側にあら力じめシボカ卩ェのような凹凸成形による装飾処 理を施しておけば加飾による意匠効果を一層向上させることができる。 [0014] In addition to the above, the outer surface sheet (10) may be configured by using a sheet in which a transparent acrylic resin is provided on the front side and a transparent ABS resin is provided on the back side, and these are bonded together. This makes it possible to compensate for the disadvantages of the acrylic resin sheet, which is slightly inferior in impact resistance, and the ABS resin sheet, which is slightly inferior in surface quality and somewhat lacking in high-class feeling due to the refractive index. Can be obtained. Further, if the hard coat treatment is applied to the sheet surface, scratching can be suppressed and a high-class feeling can be maintained for a long time. Furthermore, if the surface of the film sheet (12) on the back side is reinforced and decorated by uneven molding such as shibokae, the design effect by decoration can be further improved.

[0020] なお、上記のように、フィルムシート(12)に PP榭脂を用いた場合には、 PPが他の榭 脂と比較して安価であるとともに、製造時における炭酸ガスの発生量が少ないことか ら、環境に対する負荷が小さぐまた有害な触媒を使用していないことから、より環境 保護に適した構成となる。 [0020] As described above, when PP resin is used for the film sheet (12), PP is less expensive than other resins, and the amount of carbon dioxide generated during production is low. Since the amount is small, the load on the environment is small and no harmful catalyst is used, so the configuration is more suitable for environmental protection.
[0021] また、水分透過性のきわめて低い PPのようなポリオレフイン系榭脂が、硬質ウレタン フォーム断熱材(9)の層と透明の外面シート(10)との間に介在していることから、外 面シート(10)を介して外部から侵入する水や洗剤がフィルムシート (12)で阻止される
ため、断熱材(9)内に侵入してウレタンフォームを加水分解させることによる劣化や亀 裂の発生を抑制することができ、断熱性能の低下を防ぐことができる。 [0021] In addition, a polyolefin resin such as PP having a very low water permeability is interposed between the layer of the hard urethane foam heat insulating material (9) and the transparent outer sheet (10). Water or detergent entering from the outside through the outer sheet (10) is blocked by the film sheet (12). Therefore, it is possible to suppress deterioration and cracking caused by intruding into the heat insulating material (9) and hydrolyzing the urethane foam, and it is possible to prevent a decrease in heat insulating performance.
[0022] さらに、フィルムシート(12)をポリオレフイン系榭脂にすることで、ポリウレタンの発泡 体内部から発生する有機ガスによる前記透明の外面シート(10)へのソルベントクラッ クを低減でき、品質信頼性を向上させることができる。 [0022] Further, by making the film sheet (12) a polyolefin resin, it is possible to reduce the solvent cracks on the transparent outer sheet (10) due to the organic gas generated from the inside of the polyurethane foam. Can be improved.
[0023] フィルムシート(12)とウレタンフォーム断熱材(9)との間に設けたバインダー層(15) は、前述のノインダー(13)と同様、熱可塑性ウレタン榭脂ゃ酢酸ビニル榭脂、塩ィ匕 ビュル 酢酸ビュル共重合体、熱可塑性ポリエステル榭脂、ポリアミド榭脂、アイオノ マー榭脂、塩素化ポリオレフインなどの樹脂で形成すればよぐこのバインダー層(15 )によって、発泡断熱材(9)がフィルムシート(12)に強固に接着することから、断熱箱 、例えば、断熱扉(2)として構造体の形状が保持されるとともに、大きな剛性強度を 保有することができるものである。 [0023] The binder layer (15) provided between the film sheet (12) and the urethane foam heat insulating material (9) is made of thermoplastic urethane resin, vinyl acetate resin, salt, as with the above-mentioned noinder (13). Büll Bule Acetic acid bule copolymer, Thermoplastic polyester resin, Polyamide resin, Ionomer resin, Chlorinated polyolefin, etc. This binder layer (15) can be used for foam insulation (9) Is firmly adhered to the film sheet (12), so that the shape of the structure can be maintained as a heat insulating box, for example, a heat insulating door (2), and a large rigidity can be maintained.
[0024] また、この実施例におけるバインダー層(15)は、フィルムシート(12)面に施した火 炎による表面処理で粗表面化したり、後述するように、発泡断熱材 (9)側に不透明層 (14)を配置させることによるウレタンフォームとの密着性を向上させた構成を採用す ることで不要とすることができる。 In addition, the binder layer (15) in this example is roughened by a surface treatment with a flame applied to the surface of the film sheet (12), or is opaque on the side of the foam insulation (9) as described later. It can be made unnecessary by adopting a structure in which the adhesion with the urethane foam is improved by arranging the layer (14).
[0025] 上記実施例においては、加飾印刷(11)を施す箇所を、フィルムシート(12)の表面 に配置した力 図 4に示すように、フィルムシート )を透明体としてその下層に配 置するようにしてもよぐ下層に配置した場合は、前記ノ インダー( )はフィルムシ ート )の上層に位置することから、バインダー )を印刷する前に加飾印刷( 11' )の層を乾燥処理する必要がなぐ製造工程を簡素化することができる。 [0025] In the above embodiment, the force for placing the decorative print (11) on the surface of the film sheet (12), as shown in Fig. 4, the film sheet) is placed in the lower layer as a transparent body. If it is placed in the lower layer, the noinder () is located in the upper layer of the film sheet). The manufacturing process which does not need to be dried can be simplified.
[0026] なお、不透明層(14)は、印刷のみでなくローラーコートで形成してもよいものであり 、また、前記フィルムシート( )の発泡断熱材(9' )側の面に施してもよ!、。このよ うに設けることで、フィルムシート(12' )が一般に断熱材である硬質ウレタンフォーム と接着しにくいポリプロピレンフィルムであっても、不透明層 )に含まれる榭脂成 分によってウレタンフォームとの密着性が向上し、より強固に断熱材(9' )と接着させ ることができるものであり、この場合、図 5に示すように、発泡断熱材(9〃 )との間にバ インダ一層(15)を設ける必要がないため、コスト的に低減できる効果を奏する。
[0027] 以下、図 6により、前記 1実施例の冷蔵庫扉(2)における外板 (6)の 1製造工程に ついて詳細に説明する。まず、(a)に示すように、 PP榭脂からなるフィルムシート(12) の上面に白色の不透明インクの層(14)を設ける。これは前述のように、スクリーン印 刷でもローラーコートでもよい。次に、(b)で、前記不透明層(14)の上面にグラビア印 刷などで加飾印刷(11)を施す。また、多色にするために複数回印刷をおこなうように してちよい。 [0026] The opaque layer (14) may be formed not only by printing but also by roller coating, and may be applied to the foam insulation (9 ') side surface of the film sheet (). Yeah! In this way, even if the film sheet (12 ') is generally a polypropylene film that is difficult to adhere to the hard urethane foam that is a heat insulating material, the adhesiveness to the urethane foam is determined by the resin component contained in the opaque layer. In this case, as shown in FIG. 5, a single layer of binder (15 mm) is formed between the foam insulation (9 mm) and the heat insulation material (9 ′). ), There is no need to provide this, so that the cost can be reduced. Hereinafter, with reference to FIG. 6, one manufacturing process of the outer plate (6) in the refrigerator door (2) of the first embodiment will be described in detail. First, as shown in (a), a layer (14) of white opaque ink is provided on the upper surface of a film sheet (12) made of PP resin. As described above, this may be screen printing or roller coating. Next, in (b), decorative printing (11) is performed on the upper surface of the opaque layer (14) by gravure printing or the like. It is also possible to print multiple times to achieve multiple colors.
[0028] 次いで、(c)で、加飾印刷層の表面に透明のバインダー(13)を塗布する。このとき( d)として、次工程までの間の埃の付着や傷付きを防ぐために、一時的に表面を保護 フィルム(16)で覆うようにし、次に (e)として、扉形成時にウレタンフォーム断熱材(9) と接触する面に、前記バインダー (13)と基本的に同仕様のバインダー層(15)を配設 して積層された加飾シート(17)を形成する。 [0028] Next, in (c), a transparent binder (13) is applied to the surface of the decorative print layer. At this time, as (d), the surface is temporarily covered with a protective film (16) to prevent dust adhesion and scratches until the next process, and then (e) as urethane foam when the door is formed. On the surface in contact with the heat insulating material (9), a decorative sheet (17) is formed by laminating a binder layer (15) having basically the same specifications as the binder (13).
[0029] 次ステップにおいては、(f)に示すように、この加飾シート(17)における前記バイン ダー(13)の保護フィルム(16)を除去し、その上面にアクリル榭脂からなる外面シート( 10)を加熱装置(18)を有するプレス機(19)によって加熱圧着する。このときのプレス 圧力は約 lOkgZcm2であり、密着させる温度は 150°C、加圧時間は 30秒間に設定 する。これにより、バインダー (13)が融解し、加飾シート (17)と外面シート(10)とが密 着状態に接着され、 (g)に示す積層シート (20)が形成される。 In the next step, as shown in (f), the protective film (16) of the binder (13) in the decorative sheet (17) is removed, and an outer sheet made of acrylic resin on the upper surface thereof (10) is thermocompression-bonded by a press machine (19) having a heating device (18). Pressing pressure at this time is about lOkgZcm 2, the temperature is brought into close contact is set to 0.99 ° C, pressing time 30 sec. As a result, the binder (13) is melted, and the decorative sheet (17) and the outer sheet (10) are adhered in a sealed state to form the laminated sheet (20) shown in (g).
[0030] 次に、予備加熱して軟化させた前記積層シート (20)を、 (h)に概略的に示す成形 型 (21)に設置し、(i)のように真空ポンプ (22)で型内の空気を吸引することで積層シ ート (20)を所定形状に真空成形し、冷蔵庫扉 (2)の外板 (6)を得るものである。 [0030] Next, the laminated sheet (20) softened by preheating is placed in a mold (21) schematically shown in (h), and the vacuum pump (22) is used as shown in (i). By sucking the air in the mold, the laminated sheet (20) is vacuum formed into a predetermined shape to obtain the outer plate (6) of the refrigerator door (2).
[0031] なお、積層シート (20)を外板 (6)に成形する方法は、前記真空成形法に限るもので はなぐシート状の被成形体の成形方法である圧空成形やプレス成形によっても同 様に得ることができる。 [0031] The method of forming the laminated sheet (20) into the outer plate (6) is not limited to the above-described vacuum forming method, and may be performed by pressure forming or press forming, which is a method for forming a sheet-shaped object. It can be obtained in the same way.
[0032] 上記により所定形状に形成された外板 (6)は、前述の図 2に示すように、冷蔵室の 内面側を形成する内板(7)と結合し、図示しない発泡成形型内に設置してその内部 空間に硬質ウレタンフォーム断熱材 (9)の原液を注入して発泡させ、充填固化するこ とで内板(7)や外板 (6)の前記バインダー層(15)、あるいは不透明印刷層(14" )と 強固に接着した断熱材層 (9)を有する断熱扉(2)を構成するものである。
[0033] なお、上記実施例においては、冷蔵庫の冷蔵室扉を例として説明した力 これに限 ることなく野菜室や製氷室など他の扉に適用できることは言うまでもなぐさらに、扉に 限らず、本体上部のテーブル板や外側板に適用して意匠効果を向上し高級感を持 つた外郭面を形成することも可能である。 [0032] The outer plate (6) formed in a predetermined shape as described above is coupled to the inner plate (7) forming the inner surface side of the refrigerator compartment as shown in FIG.
