【０００１】
【発明の属する技術分野】
本発明は、冷蔵庫の仕切体周辺の構造に関するものである。
【０００２】
【従来の技術】
従来の冷蔵庫の仕切体の構造としては、特開平６−１５９９１８号公報がある。
【０００３】
図７は、従来の冷蔵庫の断熱箱体の斜視図である。図８は、従来の冷蔵庫の断熱箱体の仕切体の分解斜視図である。図において、１は冷蔵庫で、外箱２と内箱３と、外箱２と内箱３の間に注入、発泡された発泡断熱材により断熱箱体を構成し、仕切体４、５により内部を区画している。仕切体４は、図８に示すように、上部仕切体６とコの字状の下部仕切体７を組込み、側面に開口部８を有し、開口部８に対向した内箱３には穴（図示せず）を設け、発泡断熱材注入時、その一部を開口部８から仕切体４の前面部に注入させ、仕切体４の前面部の断熱性能の向上を図るものである。また、発泡断熱材を仕切体４に一体に構成することで、断熱箱体の強度を高めるものである。
【０００４】
【発明が解決しようとする課題】
しかしながら、上記従来の構成は、仕切体４の前面部の空間に全幅に亘って発泡断熱材を注入する構造となっているため、発泡断熱材を確実に注入することが難しく空洞が生じる課題があった。また、空洞を生じさせないために、発泡断熱材の仕切体４内部への注入量を増やすことで仕切体周辺に発泡断熱材の洩れが生じやすいという課題があった。また、仕切体４を複数の部品で構成するため、コスト的に高くなるという課題があった。
【０００５】
本発明は従来の課題を解決するもので、発泡断熱材の洩れが生じず、断熱箱体の強度を確保し、低コスト化を図るものである。
【０００６】
【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、内箱と、外箱と、前記内箱と外箱間に充填した発泡断熱材とよりなる断熱箱体の内部を仕切体で上下に区画する冷蔵庫において、前記仕切体の左右に独立した空間部を設けるとともに、前記空間部の内部に発泡断熱材接着面を増加するための格子形状リブを前記空間部の奥面から開口面に向かって垂直に設け、前記内箱の穴から開口部を通り前記空間部内に充填された前記発泡断熱材の一部と、左右の前記空間部の間にあらかじめ成形した断熱材とで前記仕切体の前面部の断熱壁を形成したものであり、発泡断熱材が仕切体の左右の一部分に一体に形成することで、発泡断熱材のシール部分を低減できるとともに、仕切体空間部の発泡断熱材との接着強度が高まり、断熱箱体の強度を高めることができる。また、左右空間部を仕切体本体と一体に成形することで部品点数が減り、低コスト化が図れる。
【０００７】
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、対向する左右空間部の間に補強リブを設けたものであり、仕切体左右の発泡断熱材との一体化に加え、仕切体自身の強度も高まり、さらに断熱箱体の強度を高めることができる。
【０００８】
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、仕切体の左右に独立した空間部を複数箇所設けるものであり、仕切体左右の発泡断熱材との結合力がさらに高まり、断熱箱体の強度を高めることができる。
【００１１】
【発明の実施の形態】
以下、本発明による冷蔵庫の実施の形態について、図面を参照しながら説明する。
【００１２】
（実施の形態１）
図１は、本発明の実施の形態１による冷蔵庫の斜視図、図２は同実施の形態の冷蔵庫の仕切体の斜視図である。図において、１１は冷蔵庫で、外箱１２と内箱１３と、外箱１２と内箱１３の間に注入、発泡された発泡断熱材により断熱箱体を構成している。仕切体１４は断熱箱体を上下に仕切り、上部に冷蔵室１６、下部に野菜室１７を区画形成している。また、１５は断熱仕切壁で下部に冷凍室１８を形成している。仕切体１４の前部左右には、それぞれ独立した空間部１９を仕切体１４と一体に成形し、開口部２０をそれぞれ有している。また、仕切体１４の前面部には凹部２１を設け、凹部２１内にあらかじめ成形した断熱材２２を挿入し、断熱材２２の前面には結露防止用の放熱パイプ２３を埋設し、金属製の前面板２４が組み込まれる。また、仕切体１４の開口部２０に対向した内箱１３には穴（図示せず）が設けられている。
【００１３】
上記構成により、外箱１２と内箱１３の間に発泡断熱材を注入し断熱箱体を形成する工程において、発泡断熱材の一部は内箱１３の穴から開口部２０を通り、仕切体１４の左右に設けた、それぞれ独立した空間部１９内に一体に成形される。したがって、従来の仕切体の前面部の空間に全幅に亘って発泡断熱材を注入する構造に比べシール部分を低減でき、発泡断熱材の洩れが生じずに断熱箱体の強度を確保できる。また、左右空間部を仕切体本体と一体に成形しているので部品点数が減り、低コスト化が図れる。また、仕切体１４の前面部の凹部２１にあらかじめ成形した断熱材２２を挿入しているので、結露防止用の放熱パイプ２３の熱が庫内に侵入するのを防止するとともに、前面板２４の結露を防止できる。
【００１４】
なお、本実施の形態では冷蔵室１６と野菜室１７を区画する仕切体１４について説明したが、断熱仕切壁１５にも同様な空間部を設け、同様に発泡断熱材を充填、適用することも可能である。上下二ヶ所の仕切部に発泡断熱材一体成形を施すことで断熱箱体の強度をさらに高めることができる。
【００１５】
（実施の形態２）
図３は、本発明の実施の形態２による冷蔵庫の仕切体の斜視図である。なお、実施の形態１と同一構成については説明を省略し、異なる部分について説明する。
【００１６】
図において、仕切体２５は冷蔵室１６と野菜室１７を上下に仕切り、仕切体２５の前部左右に独立した空間部１９と開口部２０を設け、対向する左右の前記空間部１９の間の凹部２１内に補強リブ２６を複数、仕切体２５と一体に成形している。また、あらかじめ成形した断熱材２２の補強リブ２６に対応した部分に切欠き２７を有している。
【００１７】
上記構成により、仕切体２５左右の空間部１９における発泡断熱材との一体化に加え、仕切体２５自身も補強リブ２６の補強作用により、断熱箱体の強度がさらに高まる。
【００１８】
（実施の形態３）
図４は、本発明の実施の形態３による冷蔵庫の仕切体の斜視図である。なお、実施の形態１と同一構成については説明を省略し、異なる部分について説明する。
【００１９】
図において、仕切体２８は冷蔵室１６と野菜室１７を上下に仕切り、仕切体２８の側面左右に独立した複数の空間部１９、１９ａ、１９ｂと開口部２０、２０ａ、２０ｂを設けている。
【００２０】
上記構成により、仕切体２８は左右に複数の空間部１９、１９ａ、１９ｂを設けているので、仕切体２８の左右側面の発泡断熱材との結合力がさらに高まり、断熱箱体の強度を高めることができる。
【００２１】
（実施の形態４）
図５は、本発明の実施の形態４による冷蔵庫の仕切体の斜視図、図６は、図５のＡ部拡大透視図である。なお、実施の形態１と同一構成については説明を省略し、異なる部分について説明する。
【００２２】
図において、仕切体２９は冷蔵室１６と野菜室１７を上下に仕切り、仕切体２９の側面左右に独立した空間部１９と開口部２０を設けている。空間部１９の内部には発泡断熱材接着増面処理としての格子状リブ３０を空間部１９の開口面２０に垂直になるように奥面から設けている。
【００２３】
上記構成により、仕切体２９は左右に空間部１９を設け、空間部１９の内部には発泡断熱材接着増面処理としての格子状リブ３０を空間部１９の開口面２０に垂直になるように設けているので、発泡断熱材の流れ性を阻害することなく仕切体空間部１９の発泡断熱材との接着強度が高まり、断熱箱体の強度を高めることができる。
【００２４】
【発明の効果】
以上説明したように請求項１に記載の発明は、内箱と、外箱と、前記内箱と外箱間に充填した発泡断熱材とよりなる断熱箱体の内部を仕切体で上下に区画する冷蔵庫において、前記仕切体の左右に独立した空間部を設けるとともに、前記空間部の内部に発泡断熱材接着面を増加するための格子形状リブを前記空間部の奥面から開口面に向かって垂直に設け、前記内箱の穴から開口部を通り前記空間部内に充填された前記発泡断熱材の一部と、左右の前記空間部の間にあらかじめ成形した断熱材とで前記仕切体の前面部の断熱壁を形成したことにより、仕切体空間部の発泡断熱材との接着強度が高まり、断熱箱体の強度を高めることができる。また、発泡断熱材のシール部分を低減でき、発泡断熱材の洩れが生じない。また、左右空間部を仕切体本体と一体に成形することで部品点数が減り、低コスト化が図れる。
【００２５】
また、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、対向する左右空間部の間に補強リブを設けたものであり、仕切体左右の発泡断熱材との一体化に加え、仕切体自身の強度も高まり、さらに断熱箱体の強度を高めることができる。
【００２６】
また、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、仕切体の左右に独立した空間部を複数箇所設けるものであり、仕切体左右の発泡断熱材との結合力がさらに高まり、断熱箱体の強度を高めることができる。
