Description

【0001】
【発明の属する技術分野】
この発明は業務用冷蔵庫であって、冷媒圧縮機、凝縮器、ファンモーターなど(以下、機械部という)を本体上部に取り付けたタイプの冷蔵庫の機械部カバーに関する。
【0002】
【従来の技術】
機械部を本体上部に取付けた業務用冷蔵庫は、図4に示すように機械部M(図1参照)の目隠しとして本体10の上部の少なくとも前面に機械部カバー11が取り付けられ、その機械部カバー11の前面に外気取り入れ口12が開口し、その構造は図4のように機械部カバー11の中程横方向に段部13が形成され、その段部13に小孔14を多数穿設している。
【0003】
【発明が解決しようとする課題】
ところが冷蔵庫本体10の前面横方向に段部13が形成されると、その部分に塵埃がたまりやすくなっている。
【0004】
このような状況から最近では、図5、図6に示すように機械部カバー11前面の段部をなくし、機械部カバー11の下端に外気取り入れ口12を設けたものに変わってきている。
【0005】
このように機械部カバー11の下端に外気取り入れ口12を開口させると、その直下にガスケット15を嵌めた扉16の上端が存在し、機械部にたまった塵埃は、扉16を開閉するたびに飛散しガスケット15上、または冷蔵庫内に降下する恐れがある。
【0006】
上記の状況に鑑みこの発明は、機械部カバー11の下端から外気を取り入れるようにして塵埃が溜まる段部をなくし、前面をスッキリさせ、扉の開閉時には塵埃がガスケットや庫内に降下しないようにした業務用冷蔵庫の機械部カバーを供することを課題とする。
【0007】
【課題を解決するための手段】
上記課題を解決するためにこの発明は、冷蔵庫本体の上部に冷媒圧縮機、ファンモーター、凝縮器からなる機械部を配設した業務用冷蔵庫において、前記機械部の前面に取付けられたカバーの下端に外気取り入れ口を開口し、その外気取り入れ口に、塵埃飛散防止手段を嵌め込んだものであり(請求項1)、上記塵埃飛散防止手段は、フィンを一体成形した樹脂成形枠体(請求項2)、またはネット状フィルターを一体に成形した樹脂成形枠体(請求項3)としたものである。
【0008】
上記の如く構成するこの発明によれば、機械部カバーの外気取り入れ口を、前面から下端面に移すことにより塵埃がたまる段部がなくなって外観がスッキリし、下端面に移した外気取り入れ口に、フィンを一体成形した樹脂成形枠体、またはネット状フィルターを一体に成形した樹脂成形枠体を嵌め込むことにより、直下にあるガスケットを取付けた扉あるいは庫内に塵埃が飛散するのを防止することができる。
【0009】
【発明の実施の形態】
次にこの発明の実施形態を図面を参照しながら説明する。図1と図2(a)は、第一実施例で、冷蔵庫本体10の上部には、冷媒圧縮機M1 とファンモーターM2 と凝縮器M3 とからなる機械部Mが配設され、その前方で冷蔵庫本体10の前面とほぼ同じ面に機械部カバー11が取り付けられている。

【0011】
上記樹脂成形枠体19は、外気取り入れ口12の内縁を挟むように嵌まる断面コ字状の廻り縁になって簡単に嵌まるようになっている。
【0012】
この実施例において、運転が開始されると冷媒圧縮機M1 とファンモーターM2 と凝縮器M3 が作動して外気取り入れ口12から外気が取り入れられ、凝縮器M3 と冷媒圧縮機M1 が冷却される。
【0013】
冷蔵庫本体10内の上部には蒸発器20と冷気を循環させるファンモーター21が配設され、ファンモーター21により庫内に放出された冷気は循環路22を経て循環するようになっている。
【0014】
図2(b)は、第二実施例で冷蔵庫本体10の上部に機械部Mが配設され、その前方で冷蔵庫本体10の前面とほぼ同じ面に機械部カバー11が取り付けられている。
【0015】
この機械部カバー11は、その下端に外気取り入れ口12が開口し、その外気取り入れ口12には、14メッシュのネット状フィルター18の縁を一体に成形した樹脂成形枠体19が嵌め込まれ、上記樹脂成形枠体19は外気取り入れ口12の内縁を挟むように嵌まる断面コ字状の廻り縁になって簡単に嵌まるようになっている。なお、ネット状フィルターの網目は10〜18メッシュの範囲で選択する。細かすぎると目詰まりがおこり、粗くなるど塵埃の降下防止の効果が得られない。
【0016】
この実施例では、外気取り入れ口12から取り込まれた外気はネット状フィルター18を経て凝縮器M3 と冷媒圧縮機M1 を通過しそれぞれを冷却する。
【0017】
【発明の効果】
以上説明した通りこの発明によれば、機械部カバーの下端から外気を取り入れ機械部を冷却するようにしたので、機械部カバーの前面がスッキリして塵埃が溜まる部分がなくなり、外気取り入れ口にフィンまたはネット状フィルターを設けたことにより、扉を開閉したときの振動で、扉の上部分や冷蔵庫内に塵埃が降下するのを防止することができる。
