次に上記構成の作用・効果を説明する。Next, the functions and effects of the above configuration will be explained.

冷却運転時には、第１図矢印のように冷気は庫内を循環
している。During cooling operation, cold air circulates within the refrigerator as shown by the arrow in FIG.

ファン７より吐出された冷気の一部は冷凍室側吐出孔８
ａより冷凍室３に入り、冷凍室側吸入孔８よりもどると
ともに残りの冷気は吐出ダクト９を通り吐出孔２１より
冷蔵室４内に吐出され冷蔵室天面に設けられた吸入孔１
４を通り凹溝１３、貫通孔１７、冷却器６へと循環して
いる。A part of the cold air discharged from the fan 7 is transferred to the freezer compartment side discharge hole 8
The cold air enters the freezer compartment 3 from a, returns through the freezer compartment side suction hole 8, and the remaining cold air passes through the discharge duct 9 and is discharged into the refrigerator compartment 4 from the discharge hole 21.
4 and circulates to the groove 13, the through hole 17, and the cooler 6.

このとき、吸入孔１４を有する吸入ダクト１０を冷蔵室
天面に設置することにより吐出孔２１より比較的離れた
位置に吸入孔１４が設置できショートサーキットするこ
となく冷蔵室内の温度分布を適正化している。At this time, by installing the suction duct 10 having the suction hole 14 on the top surface of the refrigerator compartment, the suction hole 14 can be installed at a position relatively distant from the discharge hole 21, and the temperature distribution in the refrigerator compartment can be optimized without causing a short circuit. ing.

又、吸入ダクト１０は内箱の凹陥部１６に設置されてい
る為、仕切壁２′より下方にはみ出すことなく、食品収
納スペースが確保されている。Further, since the suction duct 10 is installed in the recessed part 16 of the inner box, it does not protrude below the partition wall 2', and a food storage space is secured.

本考案は上記したように、冷蔵室内箱天面部に凹陥部を
形成し、この凹陥部に溝付の成形断熱材を配置して内箱
と成形断熱材との間に冷蔵室側吸入ダクトを形成してい
るので、吐出孔より比較的離れた位置に吸入孔が設置で
き、ショートサーキットすることなく冷蔵室内の温度分
布を適正化できる。As described above, the present invention forms a concave part on the top surface of the refrigerator compartment box, arranges a grooved molded heat insulating material in this concave part, and creates a refrigerator compartment side intake duct between the inner box and the molded heat insulating material. Because of this, the suction hole can be installed at a position relatively distant from the discharge hole, and the temperature distribution within the refrigerator compartment can be optimized without short circuiting.

又、吸入ダクトは、仕切壁より下方にはみ出すことなく
食品収納スペースを確保できる更に、風路として内箱と
一体に設けた仕切壁を貫通するのは吸入側の貫通孔のみ
であり、そのシール作業が簡単で、かつ短い寸法ですむ
ため、従来に比べて組立が容易で、また低コストに製造
できる等の効果を有する。In addition, the suction duct can secure food storage space without protruding below the partition wall.Furthermore, only the through hole on the suction side penetrates the partition wall, which is integrated with the inner box as an air path, and its seal Since the work is simple and the dimensions are short, it is easier to assemble and can be manufactured at a lower cost than conventional methods.
