Description

【０００１】
【発明の属する技術分野】
本発明は貯蔵庫本体の前面開口を観音開き式扉にて開閉する貯蔵庫に関する。
【０００２】
【従来の技術】
冷蔵庫本体の前面開口を観音開き式に開閉する左右の扉を備え、左右両扉が閉じたとき対向する扉側面間の隙間をガスケットでシールする冷蔵庫がある（例えば、特許文献１参照）。
【０００３】
この冷蔵庫においては、左右両扉間の隙間は二つのガスケットによってシールされる構造であり、しかも、一方のガスケットは左右両扉間の隙間の前端部に取り付けられていて、左右両扉の前面の縁を覆う形態であり、ガスケットが冷蔵庫の前面に露出する。また他方のガスケットは一方の扉の裏側に取り付けられていて、他方の扉に取り付けられた定規縁と密着する構成である。このため、部品数が多く、構造が複雑である。

【０００５】
【発明が解決しようとする課題】
従来の冷蔵庫では、左右両扉の裏側の左右両側に縦方向へ延びて対向する突壁を合成樹脂製の裏板の屈曲にて一体形成し、この突壁相互間に物品を載置する棚を設ける構成において、この突壁の外側にガスケット取り付け用の溝を裏板の屈曲によって形成し、扉の表板を扉の側面から裏側へ屈曲してフランジを形成し、このフランジに前記溝の外側に形成した裏板のフランジを重ね合わせて扉の表板と裏板とのシール部を構成している。しかし、このフランジの重ね合わせ部の存在によって前記突壁を扉の側面に寄せることができず、前記棚の幅を広くできない問題があった。
【０００６】
本発明では、観音開き式に開閉する左右の扉を備えた冷蔵庫等の貯蔵庫において、前記棚の幅を広くできる構成を提供する。特に、左右両扉が閉じたとき対面する側面に相互に密着し合うガスケットを設けて、左右の扉間のシールを達成する場合、ガスケットの取り付けとシール構成を改良することによって、前記棚の幅を広くできる構成を提供する。
【０００７】
【課題を解決するための手段】
本発明の貯蔵庫の扉装置は、貯蔵庫本体の前面開口を観音開き式に開閉する左右の扉を備え、前記左右両扉は、閉じたとき対面する側面に相互に密着し合うガスケットを備えた貯蔵庫において、前記左右両扉の対面する側面には前記扉の表板と裏板とを連結する扉キャップを設け、この扉キャップには前記ガスケットの第１の取り付け基部と第２の取り付け基部がそれぞれ取り付けられる前記側面側の第１溝と後部側の第２溝を備え、前記裏板と前記扉キャップとの連結は、前記扉キャップから後方へ延びる係止凸部又は係止凹部に前記裏板に一体形成した縦方向へ延びる突壁の外側壁から前方へ延びる係止凸部又は係止凹部が弾力的に嵌合し、この嵌合部分を覆うように前記第２の取り付け基部の前記突壁側部分が前記外側壁に当接することを特徴とする。
【０００８】
このように前記扉の裏板に係止凸部又は係止凹部が形成されることによって前記裏板の補強になると共に、係止凸部と係止凹部が弾力的に嵌合する構成によって、所期のシール構造が達成できると共に組み立てし易く、また扉の裏側に形成する棚の幅を広くできる構成となる。
【０００９】
また、本発明は、貯蔵庫本体の前面開口を観音開き式に開閉する左右の扉を備え、前記左右両扉は、閉じたとき対面する側面に相互に密着し合うガスケットを備えた貯蔵庫において、前記左右両扉の対面する側面に前記扉の表板と裏板とを連結する扉キャップを設け、前記扉キャップには前記左右両扉の隙間へ向けて開放した第１溝と後部に後方へ向けて開放した第２溝を備え、前記ガスケットはその第１の取り付け基部と第２の取り付け基部がそれぞれ前記第１溝と第２溝によって保持され、前記表板と前記扉キャップとの連結は、前記扉キャップの前部に形成した溝に前記表板の側端部が嵌合し、前記裏板と前記扉キャップとの連結は、前記第２溝の内側位置において前記扉キャップから後方へ延びる係止凸部又は係止凹部に前記裏板に一体形成した縦方向へ延びる突壁の外側壁から前方へ延びる係止凸部又は係止凹部が弾力的に嵌合し、この嵌合部分を覆うように前記第２の取り付け基部の前記突壁側部分が前記外側壁に当接する構成としたことを特徴とする。
【００１０】
これによって、上記の効果に加えて、扉キャップと表板及び裏板との連結は、手間のかかる多数の螺子止め構造に比して組み立てし易い構造となり、しかも、発泡充填される断熱材の漏れが防止できる扉構成となる。
【００１１】
また本発明は、前記扉キャップはプラスチック製であってその前部に窪みによって前記左右両扉の開閉用取っ手を一体に形成したことを特徴とする。これによって、上記効果に加えて、ガスケットの取り付けのための扉キャップと取っ手が別個の場合に比して、扉キャップと一体に取っ手の形成がし易くなり、構成の簡素化が図れる。
【００１２】
【発明の実施の形態】
次に、本発明の実施の形態について説明する。各図は本発明の実施形態を示しており、図１は本発明に係る貯蔵庫の正面斜視面、図２は図１に示す貯蔵庫の観音開き式扉の両扉の近接する上部裏側の斜視図、図３は図１に示す貯蔵庫の観音開き式扉相互が近接する側の一方の扉の部分断面図、図４は図１に示す貯蔵庫の観音開き式扉のヒンジ側の断面図である。
【００１３】
これらの図において、1は貯蔵庫の一つである冷蔵庫であり、前面開口の冷蔵庫本体２内を区画して複数の貯蔵室を形成し、これら各貯蔵室の前面は扉で開閉できる構成である。この冷蔵庫において、断熱箱体を構成する冷蔵庫本体２は、外箱（外壁板）と内箱（内壁板）との間に形成される断熱材充填空間に発泡性断熱材を充填した断熱構造である。冷蔵庫本体２内には、貯蔵室として上から冷蔵室３、野菜室４、冷凍室５が区画されて設けられ、冷蔵室３の前面開口は、冷蔵庫本体２の右側と左側にそれぞれ上下配置のヒンジ装置６Ａ、６Ｂにて横方向に回動して開閉される観音開き式の冷蔵室扉７Ａ、７Ｂにて閉塞される。
【００１４】
野菜室４の前面開口は、野菜室４内に設けた左右のレールとローラの組み合わせによる引き出し装置によって前後方向へ引き出し可能に支持した野菜容器と共に前方へ引き出される引き出し式扉８にて閉塞されている。冷凍室５の前面開口は、冷凍室５内に設けた左右のレールとローラの組み合わせによる引き出し装置によって前後方向へ引き出し可能に支持した容器と共に前方へ引き出される引き出し式扉９にて閉塞されている。冷蔵室３、野菜室４及び冷凍室５は、冷媒の圧縮機、冷媒の凝縮器、冷却器（冷媒の蒸発器）等を含む冷凍システムによって所定の温度に冷却される。
【００１５】
冷蔵室扉７Ａ、７Ｂが開かれた状態では、冷蔵室３の前面開口は開放され、冷蔵室扉７Ａ、７Ｂが閉じたときには、冷蔵室扉７Ａ、７Ｂの裏側の三辺を密閉する裏面ガスケット１０Ａが冷蔵庫本体２の前面に密着すると共に、冷蔵室扉７Ａ、７Ｂ相互の隙間１１を密閉する側面ガスケット１０Ｂ、１０Ｂ相互が密着して、冷蔵室３を気密に保つ。このため、冷蔵室扉７Ａ、７Ｂ相互の隙間１１に対応する部分には、冷蔵室３の前面開口を縦方向に仕切る仕切りがないため、冷蔵室３の前面は大きく開放されることとなる。
【００１６】
冷蔵室扉７Ａ、７Ｂの裏側の三辺、即ち、左側の冷蔵室扉７Ａの上下の辺と左辺を密閉する裏面ガスケット１０Ａと、右側の冷蔵室扉７Ｂの上下の辺と右辺を密閉する裏面ガスケット１０Ａとは、図４に示すような同じ形状であり、同じ取り付け構造である。また、冷蔵室扉７Ａ、７Ｂ相互の隙間１１を密閉する側面ガスケット１０Ｂ、１０Ｂの形状とその取り付けは、図３に示す構成である。左扉７Ａでは、上辺と下辺の裏面ガスケット１０Ａと側面ガスケット１０Ｂの上下端が溶着にて接続され、右扉７Ｂでは、上辺と下辺の裏面ガスケット１０Ａの端部と側面ガスケット１０Ｂの上下端が溶着にて接続される。
【００１７】
冷蔵室扉７Ａ、７Ｂは、金属製等の表板１２と、プラスチック製等の裏板１３とを両者間に断熱材充填空間１４を形成するように組み合わせる。この場合、冷蔵室扉７Ａ、７Ｂが閉じたとき相互に対面する辺、即ち、両扉７Ａ、７Ｂ間に隙間１１が形成される側の辺には、表板１２と裏板１３とに渡ってプラスチック製の扉キャップ１５が設けられている。扉キャップ１５は、前部で表板１２の側端部が接合し後部で裏板１３が接合している。具体的には、扉キャップ１５の前部に形成した溝１７に表板１２の側端部が嵌合し、扉キャップ１５の後部に形成した係止凸部１８に裏板１３の係止凹部１９が弾力的に嵌合している。このように表板１２、裏板１３及び扉キャップ１５を組み合わせ、これらの間に形成された断熱材充填空間１４に断熱材１６が充填され、表板１２、裏板１３及び扉キャップ１５が断熱材１６によって接着される。断熱材１６は、発泡性のポリウレタン樹脂等が用いられる。
【００１８】
７０は扉キャップ１５の前端に取り付けた化粧板である。その取り付けは、扉キャップ１５と化粧板７０のいずれか一方に凹部または凸部を形成し、他方にこれに係合する凸部または凹部を形成して、相互の弾力性を利用して化粧板７０を扉キャップ１５の前端に取り付ける。７１は扉７Ａ、７Ｂの表板１２の端部７３を扉キャップ１５に向けて窪ませて形成した取っ手部であり、この取っ手部７１に対応する扉キャップ１５の前部の窪み７２によって、指を掛けて左右両扉７Ａ、７Ｂを開閉する取っ手が扉キャップ１５の前部に形成される。
【００１９】
冷蔵室扉７Ａ、７Ｂが閉じたとき相互に対向する辺を除く冷蔵室扉７Ａ、７Ｂの裏側の三辺には、図４に示すように、入り口が狭く奥側が広くなったガスケット取り付け用溝２３が裏板１３に形成されている。この溝２３は冷蔵室扉７Ａ、７Ｂの裏側の上記三辺に連続して形成されている。
【００２０】
裏面ガスケット１０Ａは、冷蔵室扉７Ａ、７Ｂの裏側の上記三辺に連続するように、上記三辺のコーナ部で溶着にて接続されて上記三辺に連続しており、比較的厚肉の取り付け基部２４には一体に中空の鏃状係止部２５が突出形成されている。取り付け基部２４のこの鏃状係止部２５の反対側には複数のクッション部２６が一体形成され、このクッション部２６に支えられる状態に密着部２７が一体形成されている。この密着部２７は袋状をなし、この袋内にマグネット２８が収納されている。マグネット２８は、所謂ゴム磁石と称されるような可撓性マグネットであり、略上記三辺に亘る長さで収納されている。取り付け基部２４とクッション部２６は、表板１２と裏板１３に密着しており、裏面ガスケット１０Ａ部分でのシール性を高めている。
【００２１】
ガスケット取り付け用溝２３に対する裏面ガスケット１０Ａの取り付けは、鏃状係止部２５をガスケット取り付け用溝２３に圧入する。この圧入によって鏃状係止部２５は、ガスケット取り付け用溝２３の狭い入り口を圧縮状態で通過し、奥の広がった部分へ到達したときこの圧縮が開放される。このように、ガスケット取り付け用溝２３の入り口は鏃状係止部２５が係止する狭い幅を有し、これによって、鏃状係止部２５がガスケット取り付け用溝２３の狭い入り口に係止して抜け止め状態となる。
【００２２】
扉キャップ１５は、ガスケットの取り付け部を形成するガスケットの取り付け部材としての扉枠材２０を備えている。扉枠材２０はプラスチック製であり、前部に隙間１１へ向けて開放したガスケット取り付け用第１溝２１を形成し、後部に後方へ向けて開放したガスケット取り付け用第２溝２２を形成している。このように、ガスケット取り付け用第１溝２１と第２溝２２は、略９０度異なる向きに形成されている。扉枠材２０は、ガスケット取り付け用第１溝２１と第２溝２２の壁の外側面には係止突起２９、３０が形成され、一方、扉キャップ１５にも係止突起３１、３２が形成され、扉枠材２０自身の弾力性を利用して扉キャップ１５の係止突起３１、３２に係止突起２９、３０を係止させることにより、扉枠材２０は扉キャップ１５の台座部３３に当接保持される。ガスケット取り付け用第１溝２１と第２溝２２は、いずれも入り口が狭く奥側が広くなった形状をなしている。扉キャップ１５と扉枠材２０は、略扉７Ａ、７Ｂの対面する側面の長さにわたる長さを有している。
【００２３】
側面ガスケット１０Ｂは、略扉７Ａ、７Ｂの対面する側面の縦方向の長さにわたる長さを有し、比較的厚肉の第１の取り付け基部４４には一体に第１の鏃状係止部４５が突出形成されている。取り付け基部４４のこの鏃状係止部４５の反対側には複数のクッション部４６が一体形成され、このクッション部４６に支えられる状態に袋状の密着部４７が一体形成されている。この密着部４７の袋内にはマグネット４８が収納されている。マグネット４８は、所謂ゴム磁石と称されるような可撓性マグネットであり、略側面ガスケット１０Ｂの長さに亘って収納されている。
【００２４】
側面ガスケット１０Ｂには、取り付け基部４４のこの鏃状係止部４５と略９０度の位置に、第１の取り付け基部４４と密着部４７を形成する袋状部とから延びたヒレ部に連続した比較的厚肉の第２の取り付け基部４９が形成され、この第２の取り付け基部４９には、取り付け基部４４の鏃状係止部４５と略９０度の位相を持つ位置に一体に第２の鏃状係止部５０が突出形成されている。これによって、第１の鏃状係止部４５は扉７Ａ、７Ｂの左右方向に向いた状態となり、第２の鏃状係止部５０は扉７Ａ、７Ｂの前後方向へ向いた状態となる。
【００２５】
ガスケット取り付け用溝２１、２２に対する側面ガスケット１０Ｂの取り付けは、鏃状係止部４５をガスケット取り付け用溝２１に圧入し、鏃状係止部５０をガスケット取り付け用溝２２に圧入する。この圧入によって鏃状係止部４５は、ガスケット取り付け用溝２１の狭い入り口を圧縮状態で通過し、奥の広がった部分へ到達したときこの圧縮が開放される。このように、ガスケット取り付け用溝２１の入り口は鏃状係止部４５が係止する幅を有する。これによって、鏃状係止部４５がガスケット取り付け用溝２１の狭い入り口に係止して抜け止め状態となる。また、この圧入によって鏃状係止部５０は、ガスケット取り付け用溝２２の狭い入り口を圧縮状態で通過し、奥の広がった部分へ到達したときこの圧縮が開放される。このように、ガスケット取り付け用溝２２の入り口は鏃状係止部５０が係止する幅を有する。これによって、鏃状係止部５０がガスケット取り付け用溝２２の狭い入り口に係止して抜け止め状態となる。ガスケット１０Ｂの取り付けは、上記の圧入に限らず扉枠材２０の端から挿入するかその他の方法によることもできる。
【００２６】
扉７Ａ、７Ｂ共に上記のような構成でガスケット１０Ａ及び１０Ｂが取り付けられており、ガスケット１０Ａは冷蔵庫本体２の前面開口の前面にマグネット２８の吸着によって密着部２７が密着し、一方、扉７Ａ、７Ｂ相互間の隙間１１では、扉７Ａ、７Ｂの対面する側面にそれぞれ取り付けたガスケット１０Ｂ、１０Ｂに収納したマグネット４８相互の吸着力によって密着部４７相互が密着することによって、扉７Ａ、７Ｂ相互間の隙間１１はシールされる。
【００２７】
ここで、本発明は、扉７Ａ、７Ｂの裏側の左右両側には縦方向へ延びた対向する突壁１３Ａが、合成樹脂製の裏板１３の屈曲にて一体形成され、この突壁１３Ａ、１３Ａ間に物品を載置する棚７４を形成する構成において、側面ガスケット１０Ｂの取り付けを伴う断熱材１６の漏れを防止した新規なシール構造によって、棚７４の左右方向の横幅を大きくすることができる構造を提供する。
【００２８】
このため、本発明では、扉キャップ１５の後部に形成した係止凸部１８に裏板１３の係止凹部１９が弾力的に嵌合する構成を採用することによって、構造が簡素化され、組み立てをし易く製造コストも安くなり、しかも扉キャップ１５と裏板１３との間のシールも良好となり、断熱材１６が漏れることを防止できるものとなる。また、左右両扉に断熱材を発泡充填する際に扉体を保持する治具を特別複雑な構成にすることなく、発泡充填される断熱材の漏れが防止できる構成となる。
【００２９】
具体的には、本発明では、扉７Ａ、７Ｂの裏側の左右両側には縦方向へ延びた対向する突壁１３Ａが、合成樹脂製の裏板１３の屈曲にて一体形成され、この突壁１３Ａ、１３Ａ間に物品を載置する棚７４を取り付けることができる構成である。扉キャップ１５は、前部で表板１２の側端部が接合し後部で裏板１３が接合して、扉７Ａ、７Ｂの側面にガスケット１０Ｂの取り付け部を形成している。この場合、扉キャップ１５の前部に形成した溝１７に表板１２の側端部を嵌合させた組み合わせ状態において、表板１２のガスケット１０Ａが巡る３辺では、表板１２の裏側のフランジ１２Ａに裏板１３の周辺フランジ１３Ｂに螺子止め等によって結合し、扉キャップ１５側では、扉キャップ１５の後部に後方へ延びるように形成した係止凸部１８に、裏板１３の突壁１３Ａの外側壁から前方へ延びた係止凹部１９を弾力的に嵌合させる。
【００３０】
このように表板１２、裏板１３及び扉キャップ１５を組み合わせ、これらの間に形成された断熱材充填空間１４に断熱材１６が充填され、表板１２、裏板１３及び扉キャップ１５が断熱材１６によって接着される。断熱材１６は、発泡性のポリウレタン樹脂等が用いられる。この断熱材１６が発泡充填された扉体のガスケット取り付け用溝２３にガスケット１０Ａを取り付け、ガスケット取り付け用溝２１、２２にガスケット１０Ｂを取り付ける。
【００３１】
このように、本発明は、扉７Ａ、７Ｂの対面する側面にガスケット１０Ｂを取り付ける扉構成において、扉７Ａ、７Ｂの対面する側面に表板１２と裏板１３とを連結する扉キャップ１５を設け、この扉キャップ１５にガスケット１０Ｂを取り付ける構成とする。この場合、扉キャップ１５と表板１２及び裏板１３との連結を螺子止め構造とすると製造の手間が多くコストアップとなるが、本発明では上記のように、表板１２と扉キャップ１５との連結は、扉キャップ１５の前部に形成した溝１７に表板１２の側端部が嵌合し、裏板１３と扉キャップ１５との連結は、扉キャップ１５の後部に形成した係止凸部１８に裏板１３の係止凹部１９が弾力的に嵌合する構成によって、組み立てをし易く製造コストも安くなり、しかも扉キャップ１５と裏板１３との間のシールも良好となり、断熱材１６が漏れることを防止できる。
【００３２】
このように本発明によって、観音開き式扉を備えた貯蔵庫の左右扉間のシール装置として、対向する左右扉の側面に相互に密着するガスケット方式を採用することに適した冷蔵庫を提供できることとなる。そして、表板１２のガスケット１０Ａが巡る３辺では、表板１２の裏側のフランジ１２Ａに裏板１３の周縁フランジ１３Ｂが重なる構成であるが、左右扉７Ａ、７Ｂの対向する側面側では、上記のように、フランジ１２Ａとフランジ１３Ｂの重なりがない新規なシール構造であるため、扉７Ａ、７Ｂの裏側に形成した棚７４の左右方向の横幅を大きくすることができる。
【００３３】
なお、扉キャップ１５の後部に後方へ延びる係止凹部を形成し、裏板１３の突壁１３Ａの外側壁から前方へ延びる係止凸部を形成して両者が弾力的に嵌合する構成にする構成でも同様の効果を奏することができる。このため、裏板１３と扉キャップ１５との連結は、扉キャップ１５に後方へ延びる係止凸部又は係止凹部を形成し、この係止凸部又は係止凹部に弾力的に嵌合する係止凹部又は係止凸部を裏板１３から前方へ延びるように形成した構成であればよい。
【００３４】
なお、扉７Ａ、７Ｂに断熱材１６を充填発泡させる場合、図４のように扉の厚さが比較的薄く側面形状が平坦な構成であれば、表板１２と裏板１３をそれぞれの治具P、Qによって抑えた状態で、断熱材充填空間１４に断熱材１６を充填しても、治具P、Qによる抑えが充分であるため断熱材１６が漏れることはない。本発明では、観音開き式扉間の隙間１１をシールするガスケット１０Ｂを扉７Ａ、７Ｂの対面する側面に取り付ける構成を採用し、扉７Ａ、７Ｂの対面する側面にガスケット取り付け用溝２１、２２を形成した扉キャップ１５を配置して、これにガスケット１０Ｂを取り付ける構成とすることによって、観音開き式扉間の隙間１１の良好なシールを達成できるものである。また、左右両扉に断熱材を発泡充填する際に扉体を保持する治具を特別複雑な構成にすることなく、断熱材１６が漏れること防止できる。
【００３５】
本発明は、上記実施形態に限定されず、他の構成の観音開き式の貯蔵庫にも適用でき、本発明の技術的範囲を逸脱しない限り種種の変更が考えられ、それに係る種種の実施形態を包含するものである。
【００３６】
【発明の効果】
本発明によって、扉の裏板に形成した係止凸部又は係止凹部によって扉の裏板の補強になると共に、扉キャップの後方へ延びる係止凸部又は係止凹部に裏板から前方へ延びる係止凸部又は係止凹部が弾力的に嵌合することによって、所期のシール構造が達成できると共に組み立てし易く、また扉の裏側に形成する棚の左右方向の横幅を大きくすることができる。このため、対向する左右扉の側面に相互に密着するガスケット方式を採用することに適した冷蔵庫を提供できることとなる。
【００３７】
また、請求項２の発明によって、上記の効果に加えて、扉キャップと表板及び裏板との連結は、手間のかかる多数の螺子止め構造に比して組み立てし易い構造となり、しかも、発泡充填される断熱材の漏れが防止できる扉構成となる。
【００３８】
また、請求項３の発明によって、上記効果に加えて、ガスケットの取り付けのための扉キャップと取っ手が別個の場合に比して、扉キャップと一体に取っ手の形成がし易くなり、構成の簡素化が図れる。
