本発明は、冷蔵庫の冷蔵室に設けたダクトに庫内照明灯を配置する構造に関するものである。  The present invention relates to a structure in which an interior lamp is arranged in a duct provided in a refrigerator compartment of a refrigerator.

従来、この種の冷蔵庫は、冷蔵室の背面に設けたダクトの一部に庫内照明灯が設けられている(例えば、特許文献1参照)。  Conventionally, in this type of refrigerator, an interior lighting lamp is provided in a part of a duct provided on the back surface of the refrigerator compartment (see, for example, Patent Document 1).

図6は、前記広報に記載された従来の冷蔵庫の部分断面を示すものである。図6に示すように、冷蔵庫1の庫内2上部に配置され、冷却器3とファン4で形成した冷気5により冷却する冷蔵室6と、この冷蔵室6の背面部7に設けた庫内照明体8と、この庫内照明体8の周囲の冷蔵室6の背面部7に設け、前記ファン4からの冷気5を導入して一方向に流下させたダクト9と、このダクト9の流下方向に沿ってダクト9から冷蔵室6内に冷気5を吹き出す複数個の吹出口10と、前記冷蔵室内6を循環した冷気5を冷却器3側に戻すように、冷蔵室6の底部11の一側に吸込み口12を設けている。また、庫内照明体8は、庫内灯13と、その庫内灯13の前面を覆って光を拡散するようにカバー14を設けている。庫内灯13は、白熱灯または発光ダイオード(LED)を複数個使用するようにしている。また、冷蔵室6内に複数個の棚15を設けるようにしている。  FIG. 6 shows a partial cross-section of a conventional refrigerator described in the public relations. As shown in FIG. 6, therefrigerator compartment 6 disposed in the upper part of therefrigerator 2 of therefrigerator 1 and cooled by thecool air 5 formed by thecooler 3 and thefan 4, and the refrigerator provided in theback surface portion 7 of therefrigerator compartment 6. Anilluminating body 8, aduct 9 provided on theback surface portion 7 of therefrigerator compartment 6 around the interiorilluminating body 8, introduced with thecool air 5 from thefan 4 to flow down in one direction, and the flow of the duct 9 A plurality ofoutlets 10 for blowing thecold air 5 from theduct 9 into therefrigerator compartment 6 along the direction, and thebottom 11 of therefrigerator compartment 6 so as to return thecool air 5 circulated through therefrigerator compartment 6 to the cooler 3 side. Asuction port 12 is provided on one side. Moreover, theinterior lighting body 8 includes an interior lamp 13 and acover 14 that covers the front surface of the interior lamp 13 and diffuses light. The interior lamp 13 uses a plurality of incandescent lamps or light emitting diodes (LEDs). A plurality ofshelves 15 are provided in therefrigerator compartment 6.

しかしながら、前記従来の構成では、庫内照明体8は、庫内灯13をカバー14により、例えば指向性の強いLED光を拡散する構成のため、冷蔵室6に複数個の棚15を設けると、光が拡散しすぎて棚15の位置により庫内の食品等が見えづらいという課題を有していた。  However, in the said conventional structure, when theinterior lighting body 8 is the structure which diffuses LED light with strong directivity by thecover 14 with the interior lamp 13, when the someshelf 15 is provided in therefrigerator compartment 6, for example, The light diffuses too much and it is difficult to see food in the cabinet due to the position of theshelf 15.

また、冷気5を一方向に向かって逆U字状に流下させたダクト9を構成しているため、冷気5が上昇する側と流下する側では、複数個の吹出口10から吹き出す冷気5の吹き出し方向が異なり、冷蔵室6内の温度分布が不均一になるという課題を有していた。  In addition, since theduct 9 in which thecool air 5 is flowed down in an inverted U shape in one direction is configured, thecool air 5 blown out from the plurality ofoutlets 10 on the side where thecool air 5 rises and on the side where it flows down. There was a problem that the blowing direction was different and the temperature distribution in therefrigerator compartment 6 became non-uniform.

本発明は、前記従来の課題を解決するもので、冷蔵庫の庫内照明体の配置により目的物の認識を容易に行うとともに庫内照明体の周囲に設けたダクトの冷気の吹き出しの均一化を行うことを目的にする。  The present invention solves the above-described conventional problems, and facilitates recognition of a target object by arranging the interior lighting body of the refrigerator, and uniformizing the blowout of cool air in the duct provided around the interior lighting body.
