【発明の属する技術分野】
本発明は外箱の天面部に開口穴を有し、その上面に物品を設置するトップテーブル付き冷蔵庫箱体に関する。
【０００２】
【従来の技術】
従来のこの種トップテーブル付冷蔵庫は例えば特開平９−２５０８６５号公報に記載されており以下図１３，１４を参照しながら説明する。１は前面を開口する冷蔵庫本体、２は冷蔵庫本体１の開口を開閉自在に閉塞する扉、３は冷蔵庫本体１の上端に装着するトップテーブルである。冷蔵庫本体１は両側壁４とこの側壁の背面側に設けられる背壁５とで形成される外箱６と、この外箱の内側で間隔を介して配置され前面を開口した内箱７と、この内箱と外箱との間及び内箱とトップテーブル３との間に充填される発泡断熱材８とで構成されている。内箱７には開口端に内側から外側に向かってフランジ９が形成され、このフランジの上端は外箱６の両側壁４及び背壁５の上端と同じ高さに形成されている。
【０００３】
トップテーブル３は外箱６の上端と内箱７のフランジ９の上端とに係止して水平に配置される合成樹脂で形成されるトップテーブル本体１０と、ステンレス等の耐熱性の金属材料で形成されるテーブル部１１とで構成されている。トップテーブル本体１０は周囲に下方に向かって折曲される折り曲げ片１２を有し、前端を外箱６より前方に突出させて扉２と同一面にしている。トップテーブル本体１０には四角形に凹所１３が形成されている。この凹所にはテーブル部１１が嵌合されている。このテーブル部は平板１４とこの平板の周囲に下方に向かって形成される脚片１５とで構成されている。テーブル部１１はトップテーブル本体１０の凹所１３に嵌め合わせることで内部に空間１６を形成している。このように構成されたトップテーブル付冷蔵庫において、冷蔵庫は外箱６と内箱７とで形成される冷蔵庫本体１の上端にトップテーブル３を組み込み、これらの間に発泡断熱材８を充填し、扉２を取り付けて形成される。
【０００４】
【発明が解決しようとする課題】
しかしながら、従来のトップテーブル付冷蔵庫では合成樹脂で形成されるトップテーブル本体１０と、ステンレス等の金属材料で形成されるテーブル部１１とで構成の為、構成が複雑で又非常にコストの高いトップテーブル構成となっていた。又、トップテーブル本体１０には四角形に凹所１３が形成され、この凹所１３に別体のテーブル部１１が嵌み合せることで内部に空間１６を形成した構造の為、断熱壁厚が薄くなり断熱性能が低下する等の問題がある。必要な断熱壁厚を確保する為には、トップテーブル本体１０と内箱７間の寸法を大きくする必要がありそのため冷蔵庫，庫内容積を減少させるか、冷蔵庫本体の高さをアップさせなければいけない等の問題があった。
【０００５】
本発明は、トップテーブルに高温の機器を設置しても変形がなく、必要な断熱壁厚を庫内容積，冷蔵庫本体の高さに影響させないコストの安い構成でトップテーブル付き冷蔵庫箱体を提供することを目的とする。
【０００６】
【課題を解決するための手段】

【０００７】
また、本発明は、外箱の天面部に設けた開口穴と相対向するトップテーブルより開口穴に突する突出リブ及び開口穴の天面部に接する当接リブを一体に設けたことにより発泡断熱材のシール部材が不用となり作業性の向上が図れる。
【０００８】
また、本発明は、外箱の天面部に放射状に相対向して複数の開口穴を設けたトップテーブル付き冷蔵庫箱体のため外箱の強度向上が図れる。
【０００９】
また、本発明は、外箱の天面部前面に数個の係止角穴を設け、角穴と相対向するトップテーブルより係止片と係止片の四方を囲むリブを一体形成し、このリブ間に発泡断熱材を充填され係止片が断熱材中に埋設したトップテーブル構成の為、別の補強板又付加部材が不用となり、コスト及び取付け工数のかからない強固な取付けが確保できるトップテーブル付き冷蔵庫箱体が提供できる。
