【0006】
【発明が解決しようとする課題】
しかしながら上記従来の構成では、断熱材1の厚みが十分取れない部位において冷蔵庫内から冷却されることにより、着色樹脂板3の表面温度が低下し、夏場の多湿条件下では着色樹脂板3の表面が発汗してしまうという欠点があった。
【0007】
本発明は上記従来の課題を解決するもので、扉表面の意匠性を高めながら、夏場の多湿条件下でも扉表面が発汗しない冷蔵庫の扉を提供することを目的とする。
【0008】
【課題を解決するための手段】
本発明の請求項1に記載の発明は、前面に透明層と奥面に着色層と裏面に良熱伝導部材とを有する着色外板と、前記着色外板に対向して設けた内板と、前記着色外板と内板の周囲に設けた枠体と、前記着色外板・枠体・内板間に発泡充填された断熱材からなるものであり、前面の透明層を通して入射し着色層で反射した光を視認することで、扉の表面の透明感、光沢、深みを得ることができ意匠性を高めることができるとともに、着色外板の熱伝導部材が扉周囲の熱を外板表面に効率よく伝え、夏場の多湿条件下でも扉体の表面の発汗を防止できる。
【0009】
請求項2に記載の発明は、請求項1に記載の発明において、着色外板の裏面に有する良熱伝導部材は、鉄板から構成されたものであり、扉表面の意匠性を高めた上で、扉体の剛性を向上させ、扉体の変形防止をしながら夏場の多湿条件下でも着色樹脂板の表面が発汗することを防ぐことができる。
【0010】
請求項3に記載の発明は、請求項1に記載の発明において、着色外板の裏面に有する良熱伝導部材は、アルミ板から構成されたものであり、扉表面の意匠性を高めた上で、熱伝導性の優れた材質により効率的に扉表面の温度上昇が可能となる。また、アルミ材は成形性に優れ、容易に外板の形状に合わせることができるので扉の形状に制約されることなく確実に発汗を防止できる。
【0011】
請求項4に記載の発明は、請求項1に記載の発明において、着色外板の裏面に有する良熱伝導部材は、アルミ塗装層から構成されたものであり、扉表面の意匠性を高めるとともに、熱伝導性の優れたアルミ塗装を用いることで、加工性を高めながら発汗を防止できる。また、扉体の軽量化を図ることができる。
【0012】
請求項5に記載の発明は、請求項1から請求項4のいずれか一項に記載の発明において、外板の裏面に設ける良熱伝導部材は前記外板の全面に配置するものであり、扉の全面に亘って発汗を防止できる。また、着色層が比較的薄く着色層の裏面側(熱伝導部材配置側)から光が透過するような場合でも、熱伝導部材を全面に配置していることで、扉前面から見た色むらを防止することができる。
【0013】
【発明の実施の形態】
以下、本発明による冷蔵庫の一実施の形態について、図面を参照しながら説明する。なお、従来と同一構成には、同一符号を付して詳細な説明を省略する。
【0014】
(実施の形態1)
図1は本発明の実施の形態1による冷蔵庫の扉の概略断面図である。図1に示すように、着色外板5は、前面に樹脂成形した透明層5aを有し、前記透明層5aの奥面に着色層5bを、たとえば塗装により形成し、着色層5bの裏面には良熱伝導部材であるアルミフィルム5cを貼り付けて構成している。
【0015】
また、着色外板5のアルミフィルム5cは、着色層5bの裏面に全面に亘って配置している。
【0016】
そして、着色外板5と、着色外板5に対向して設けた内板1と、前記着色外板5と内板1の周囲に設けた枠体4とで囲まれた空間に充填発泡した断熱材2とで扉体Bを構成している。
【0017】
以上のように構成された本実施の形態の冷蔵庫の扉体について、以下その作用を説明する。
【0018】
扉体Bを前方から見たとき、前面の透明層5aを通して光が入射し、着色層5bで反射した光を使用者が視認することで、扉の表面の透明感、光沢、深みを得ることができ、意匠性に優れたものとなる。そして、扉体Bが構造上の制約から断熱材2の厚みが十分取れない部位がある場合でも、着色外板5の裏面に設けた良熱伝導部材であるアルミフィルム5cの伝熱作用により、扉周囲の熱を外板5の表面に効率よく伝え、夏場の多湿条件下でも扉体の表面の発汗を防止できる。
【0019】
また、着色外板5のアルミフィルム5cは、着色層5bの裏面に全面に亘って配置しているので、扉の全面に亘って発汗防止の効果を高めることができる。さらに、着色層5bが比較的薄く着色層5bの裏面側(熱伝導部材5c配置側)から光が若干透過するような場合でも、熱伝導部材のアルミフィルム5cを全面に配置していることで、扉体Bを前面から見た時に、アルミフィルム5cの有無による色むらの発生を防止することができる。
【0020】
なお、着色外板5は平板状に構成してもよいが、左右両側面を湾曲させて断面U字状に成形し、上下面に枠体4を設けたもので構成してもよい。この場合、扉体左右側面部まで透明層5aおよび着色層5b、アルミフィルム5cを一体に構成することで、側面部の意匠性をさらに高めた上で、発汗を防止できる。特に側面と前面を一体に形成することで、アルミフィルム5cの側面からの伝熱作用による扉体Bの表面温度上昇効果も一層高まる。
【0021】
(実施の形態2)
図2は本発明の実施の形態2による冷蔵庫の概略断面図である。なお、実施の形態1と同一構成については詳細な説明を省略し、異なる部分についてのみ説明する。

【0024】
上記構成により、扉体Cを前方から見たとき、前面の透明層6aを通して光が入射し、着色層6bで反射した光を使用者が視認することで、扉の表面の透明感、光沢、深みを得ることができ、意匠性に優れたものとなる。そして、扉体Cが構造上の制約から断熱材2の厚みが十分取れない部位がある場合でも、着色外板6の裏面に設けた良熱伝導部材である鉄板6cの伝熱作用により、扉周囲の熱を外板6の表面に効率よく伝え、夏場の多湿条件下でも扉体の表面の発汗を防止できる。
【0025】
また、着色外板6の裏面に設けた鉄板6cにより、扉体の剛性が向上し、扉体の変形を防止できる。
【0026】

図3は本発明の実施の形態3による冷蔵庫の概略断面図である。なお、実施の形態1と同一構成については詳細な説明を省略し、異なる部分についてのみ説明する。
【0027】
図3に示すように、着色外板7は、前面に樹脂成形した透明層7aを有し、前記透明層7aの奥面に着色層7bを、たとえば塗装により形成し、着色層7bの裏面には良熱伝導部材であるアルミ板7cを貼り付けて構成している。
【0028】
そして、着色外板7と、着色外板7に対向して設けた内板1と、前記着色外板7と内板1の周囲に設けた枠体4とで囲まれた空間に充填発泡した断熱材2とで扉体Dを構成している。

【0030】
また、アルミ板7cは成形性に優れ、容易に外板の形状に合わせることができるので扉の形状に制約されることなく確実に発汗を防止できる。
【0031】
(実施の形態4)
図4は本発明の実施の形態4による冷蔵庫の概略断面図である。なお、実施の形態1と同一構成については詳細な説明を省略し、異なる部分についてのみ説明する。

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a refrigerator according to the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the same structure as the past, and detailed description is abbreviate | omitted.
[0014]
(Embodiment 1)
FIG. 1 is a schematic sectional view of a refrigerator door according to Embodiment 1 of the present invention. As shown in FIG. 1, the colored outer plate 5 has a transparent layer 5a formed by resin molding on the front surface, and a colored layer 5b is formed on the back surface of the transparent layer 5a by, for example, painting, and on the back surface of the colored layer 5b. Is formed by attaching an aluminum film 5c which is a good heat conducting member.
[0015]
Further, the aluminum film 5c of the colored outer plate 5 is disposed over the entire back surface of the colored layer 5b.
[0016]
And it filled and foamed the space surrounded by the colored outer plate 5, the inner plate 1 provided facing the colored outer plate 5, and the colored outer plate 5 and the frame 4 provided around the inner plate 1. A door body B is constituted by the heat insulating material 2.
[0017]
The effect | action is demonstrated below about the door body of the refrigerator of this Embodiment comprised as mentioned above.
[0018]
When the door B is viewed from the front, light enters through the transparent layer 5a on the front surface, and the user visually recognizes the light reflected by the colored layer 5b, thereby obtaining the transparency, gloss, and depth of the door surface. Can be achieved and has excellent design properties. And even if there is a part where the thickness of the heat insulating material 2 cannot be sufficiently removed due to structural limitations of the door body B, due to the heat transfer action of the aluminum film 5c which is a good heat conductive member provided on the back surface of the colored outer plate 5, The heat around the door is efficiently transmitted to the surface of the outer plate 5, and sweating on the surface of the door body can be prevented even under humid conditions in summer.
[0019]
Moreover, since the aluminum film 5c of the colored outer plate 5 is disposed over the entire back surface of the colored layer 5b, the effect of preventing sweating can be enhanced over the entire surface of the door. Furthermore, even when the colored layer 5b is relatively thin and light is slightly transmitted from the back surface side (the heat conducting member 5c arrangement side) of the colored layer 5b, the aluminum film 5c of the heat conducting member is disposed on the entire surface. When the door B is viewed from the front, it is possible to prevent color unevenness due to the presence or absence of the aluminum film 5c.
