上部通路９内には下方から送風ファン１０、ダンパ２３、送風ファン２４が配される。送風ファン１０は正面投影において仕切壁３６に重なる位置に配される。下部通路２９は送風ファン１０の排気側で上部通路９に対して分岐して下方に延びる。ダンパ２３は冷蔵室４及び野菜室５の冷却時に開かれ、上部通路９のダンパ２３よりも上方に形成された冷蔵用通路８に冷気を導く。送風ファン２４はダンパ２３を開いた際に駆動される。なお、ダンパ２３よりも下方の上部通路９及び下部通路２９の前面はパネル７ａによりにより覆われる。また、上部通路９のダンパ２３よりも上方の冷蔵用通路８の前面はパネル７ｂにより覆われる。 A blower fan 10, a damper 23, and a blower fan 24 are disposed in the upper passage 9 from below. The blower fan 10 is disposed at a position overlapping the partition wall 36 in front projection. The lower passage 29 diverges from the upper passage 9 on the exhaust side of the blower fan 10 and extends downward. The damper 23 is opened when the refrigerator compartment 4 and the vegetable compartment 5 are cooled, and guides cool air to the refrigerator passage 8 formed above the damper 23 in the upper passage 9. The blower fan 24 is driven when the damper 23 is opened. The front surfaces of the upper passage 9 and the lower passage 29 below the damper 23 are covered with a panel 7a. Further, the front surface of the refrigeration passage 8 above the damper 23 of the upper passage 9 is covered with a panel 7b.

上部通路９のダンパ２３よりも上方の冷蔵用通路８は冷蔵室４の背面及び天井面に沿って配され、冷蔵室４に臨む複数の吐出口８ａ〜８ｆが開口する。吐出口８ａは冷蔵室４の天井面上の冷蔵用通路８の前部に設けられる。吐出口８ｂ〜８ｄは各棚板４ｂ〜４ｅの間に設けられる。下方の吐出口８ｅ、８ｆはチルド室７０内に臨む。 The refrigeration passage 8 above the damper 23 of the upper passage 9 is arranged along the back surface and the ceiling surface of the refrigeration chamber 4, and a plurality of discharge ports 8 a to 8 f facing the refrigeration chamber 4 are opened. The discharge port 8 a is provided in the front part of the refrigeration passage 8 on the ceiling surface of the refrigeration chamber 4. The discharge ports 8b to 8d are provided between the shelf plates 4b to 4e. The lower discharge ports 8e and 8f face the chilled chamber 70.

上部通路９のダンパ２３よりも下方は野菜室５を避けて製氷室２５及び冷凍室２６の後方を通り、製氷室２５に臨む吐出口９ａ及び冷凍室２６に臨む吐出口９ｂが開口する。下部通路２９には冷凍室６に臨む吐出口２９ａ〜２９ｄが開口する。吐出口２９ａ〜２９ｃは冷凍室２６の鉛直下方に上下方向に並設される。吐出口２９ｄは野菜室５の鉛直下方に配される。 Below the damper 23 in the upper passage 9, the vegetable compartment 5 is avoided and the ice making chamber 25 and the freezing chamber 26 are passed behind, and a discharge port 9 a facing the ice making chamber 25 and a discharge port 9 b facing the freezing chamber 26 are opened. Discharge ports 29 a to 29 d facing the freezer compartment 6 are opened in the lower passage 29. The discharge ports 29 a to 29 c are arranged vertically in the vertical direction below the freezer compartment 26. The discharge port 29 d is arranged vertically below the vegetable compartment 5.

圧縮機３１及び送風ファン１０の駆動によって冷却器室１２を流通する空気と冷却器１１とが熱交換して冷気が生成される。生成された冷気は吐出口９ａから製氷室２５に吐出され、吐出口９ｂから冷凍室２６に吐出される。また、冷気は下部通路２９を流通して吐出口２９ａ、２９ｂ、２９ｃから冷凍室６に吐出される。吐出された冷気は製氷室２５、冷凍室２６及び冷凍室６内を流通し、戻り口９ｃを介して冷却器１１に戻る。これにより、製氷室２５、冷凍室２６及び冷凍室６内の冷却が行われる。 As the compressor 31 and the blower fan 10 are driven, the air flowing through the cooler chamber 12 and the cooler 11 exchange heat to generate cold air. The generated cold air is discharged from the discharge port 9a to the ice making chamber 25 and discharged from the discharge port 9b to the freezing chamber 26. Further, the cold air flows through the lower passage 29 and is discharged from the discharge ports 29a, 29b, 29c to the freezer compartment 6. The discharged cold air flows through the ice making chamber 25, the freezing chamber 26 and the freezing chamber 6 and returns to the cooler 11 through the return port 9c. Thereby, the inside of the ice making room 25, the freezing room 26, and the freezing room 6 is cooled.

ダンパ２３が開かれると上部通路９の冷蔵用通路８に冷気が流入し、吐出口８ａ、８ｂ、８ｃ、８ｄ、８ｅ、８ｆから冷蔵室４に吐出される。吐出された冷気は冷蔵室４の前方へ流通した後に下方に流通し、連通路４ｆから流出する。これにより、冷蔵室４内の冷却が行われる。 When the damper 23 is opened, cold air flows into the refrigeration passage 8 of the upper passage 9 and is discharged from the discharge ports 8a, 8b, 8c, 8d, 8e, 8f to the refrigeration chamber 4. The discharged cool air flows to the front of the refrigerator compartment 4 and then flows downward and flows out from the communication passage 4f. Thereby, the inside of the refrigerator compartment 4 is cooled.

その後、連通路４ｆを介して冷気は野菜室５内に吐出され、野菜室５内の前部から後部へと流通し、戻り通路３４を介して冷却器室１２に戻る。これにより、野菜室５内の冷却が行われる。 Thereafter, the cold air is discharged into the vegetable compartment 5 through the communication passage 4 f, circulates from the front to the rear of the vegetable compartment 5, and returns to the cooler compartment 12 through the return passage 34. Thereby, cooling in the vegetable compartment 5 is performed.

図５は断熱壁１９近傍を下方から見た斜視図であり、パネル７ａ（図３参照）及び仕切板２７（図３参照）を省いた状態を示している。断熱壁１９の仕切壁３６の後方には開口部３６ａが設けられ、冷凍室６と冷凍室２６とが連通する。開口部３６ａの後部の右側壁には傾斜面から成る気流案内部３６ｂが設けられる。気流案内部３６ｂによって上部通路９の側壁と断熱壁１９の下面により形成される冷却器室１２の上壁とが連結される。これにより、左右幅の大きい冷却器室１２から冷凍区画部２１（図１参照）の後方に配した左右幅の狭い上部通路９に円滑に冷気が流入する。従って、冷気通路７の圧力損失を低減することができる。 FIG. 5 is a perspective view of the vicinity of the heat insulating wall 19 viewed from below, and shows a state in which the panel 7a (see FIG. 3) and the partition plate 27 (see FIG. 3) are omitted. An opening 36 a is provided behind the partition wall 36 of the heat insulating wall 19, and the freezer compartment 6 and the freezer compartment 26 communicate with each other. An airflow guide portion 36b having an inclined surface is provided on the right side wall at the rear portion of the opening portion 36a. The side wall of the upper passage 9 and the upper wall of the cooler chamber 12 formed by the lower surface of the heat insulating wall 19 are connected by the airflow guide portion 36b. Thus, the cool air smoothly flows from the cooler chamber 12 having a large lateral width into the upper passage 9 having a narrow lateral width disposed behind the freezing compartment 21 (see FIG. 1). Therefore, the pressure loss of the cool air passage 7 can be reduced.

図６は断熱壁１９近傍を上方から見た斜視図を示している。断熱壁１９及び仕切壁２０の前面には冷凍サイクルを形成する放熱パイプ５２が配されている。放熱パイプ５２は水平部５２ａ及び垂直部５２ｂを有している。水平部５２ａは断熱壁１９の厚み内で蛇行し、水平方向に延びて上下に２列設けられる。垂直部５２ｂは水平部５２ａから上方に延びてＵ字状に形成され、仕切壁２０の厚み内に設けられる。 FIG. 6 shows a perspective view of the vicinity of the heat insulating wall 19 as viewed from above. A heat radiating pipe 52 forming a refrigeration cycle is disposed on the front surfaces of the heat insulating wall 19 and the partition wall 20. The heat radiating pipe 52 has a horizontal portion 52a and a vertical portion 52b. The horizontal portion 52a meanders within the thickness of the heat insulating wall 19, extends in the horizontal direction, and is provided in two rows vertically. The vertical part 52 b extends upward from the horizontal part 52 a and is formed in a U shape, and is provided within the thickness of the partition wall 20.

野菜室５の底壁を形成する断熱壁１９の後部と左側壁を形成する仕切壁２０の後部との間には気流案内部３６ｂとの干渉を回避する回避部５ｂが設けられる。尚、野菜室５内の収納ケース５０（図４参照）の側壁と底壁との間には回避部５ｂとの干渉を回避する面取り（不図示）が形成される。 Between the rear part of the heat insulating wall 19 that forms the bottom wall of the vegetable compartment 5 and the rear part of the partition wall 20 that forms the left side wall, an avoiding part 5b that avoids interference with the airflow guide part 36b is provided.

Thereby, it can prevent that an operator accidentally contacts the vertical part 52b extended upwards from the heat insulation wall 19 before installation of the partition wall 20, and damages the heat radiating pipe 52. FIG.

本実施形態によると、仕切壁２０が設置される際に嵌合部４０を溝部３７に挿入した状態で前後方向に垂直な面内で回動して段差部４３により係止されるため、仕切壁２０を容易に設置できる。このため、冷蔵庫１の製造工数を削減することができる。 According to the present embodiment, when the partition wall 20 is installed, the fitting portion 40 is inserted in the groove portion 37 and is rotated in a plane perpendicular to the front-rear direction so as to be locked by the step portion 43. The wall 20 can be easily installed. For this reason, the manufacturing man-hour of the refrigerator 1 can be reduced.

また、傾斜面４０ａと傾斜面３７ｃとの間にシール部材５３を配される。これにより、仕切壁２０の加工精度によって嵌合部４０の下端が溝部３７に対して上方向にずれても傾斜したシール部材５３により嵌合部４０と溝部３７との隙間が密閉できる。 Further, a seal member 53 is disposed between the inclined surface 40a and the inclined surface 37c. Thereby, even if the lower end of the fitting part 40 shifts upward with respect to the groove part 37 due to the processing accuracy of the partition wall 20, the gap between the fitting part 40 and the groove part 37 can be sealed by the inclined seal member 53.

また、ネジ４１の軸方向が傾斜面４０ａに略直交するため、ネジ４１の締め付けによって傾斜面３７ｃと傾斜面４０ａとの隙間を確実に密閉することができる。 In addition, since the axial direction of the screw 41 is substantially orthogonal to the inclined surface 40a, the gap between the inclined surface 37c and the inclined surface 40a can be reliably sealed by tightening the screw 41.

また、係止面４３ａが傾斜面により形成されるとともに仕切壁２０に係止面４３ａに対向する傾斜面から成る当接部４４を有し、係止面４３ａと当接部４４との間にシール部材３９を配したため、野菜室５と冷凍区画部２１との密閉性をより向上し、冷蔵庫１の冷却効率を向上することができる。 Further, the locking surface 43a is formed by an inclined surface, and the partition wall 20 has an abutting portion 44 made of an inclined surface facing the engaging surface 43a, and between the locking surface 43a and the abutting portion 44. Since the sealing member 39 is arranged, the sealing property between the vegetable compartment 5 and the freezing compartment 21 can be further improved, and the cooling efficiency of the refrigerator 1 can be improved.

また、傾斜面の係止面４３ａと当接部４４との間にシール部材３９が配される。これにより、仕切壁２０の加工精度によって当接部４４が段差部４３に対して上方向にずれても傾斜したシール部材３９により当接部４４と段差部４３との隙間が密閉される。これにより、冷蔵庫１の冷却効率を向上することができる。 Further, a seal member 39 is disposed between the inclined locking surface 43 a and the contact portion 44. Accordingly, the gap between the contact portion 44 and the stepped portion 43 is sealed by the inclined seal member 39 even if the contact portion 44 is displaced upward with respect to the stepped portion 43 due to the processing accuracy of the partition wall 20. Thereby, the cooling efficiency of the refrigerator 1 can be improved.

また、野菜室５（第１貯蔵室）が冷蔵温度に維持され、仕切壁２０により野菜室５と仕切られる冷凍区画部２１（第２貯蔵室）が冷凍温度に維持される。このため、シール部材３９やシール部材５３によって野菜室５と冷凍区画部２１との間を密閉し、温度の異なる冷気の侵入を防止できる。従って、冷蔵庫１の冷却効率を向上することができる。 In addition, the vegetable compartment 5 (first storage compartment) is maintained at the refrigeration temperature, and the freezing compartment 21 (second storage compartment) partitioned from the vegetable compartment 5 by the partition wall 20 is maintained at the freezing temperature. For this reason, between the vegetable compartment 5 and the freezer compartment 21 can be sealed by the seal member 39 and the seal member 53, and intrusion of cold air having different temperatures can be prevented. Therefore, the cooling efficiency of the refrigerator 1 can be improved.

また、仕切壁２０の前面に配置される放熱パイプ５２を仕切壁２０の設置前に溝部３７内に配置することができる。従って、仕切壁２０の設置前の放熱パイプ５２の破損を防止することができる。 Further, the heat radiating pipe 52 disposed on the front surface of the partition wall 20 can be disposed in the groove portion 37 before the partition wall 20 is installed. Therefore, damage to the heat radiating pipe 52 before the partition wall 20 is installed can be prevented.

また、上部通路９の側壁と冷却器室１２の上壁とを連結する傾斜面から成る気流案内部３６ｂを仕切壁の後端部にため、左右幅の大きい冷却器室１２から冷凍区画部２１の後方に配した左右幅の狭い上部通路９に円滑に冷気が流入する。従って、冷気通路７の圧力損失を低減することができる。 In addition, since the airflow guide portion 36b composed of an inclined surface connecting the side wall of the upper passage 9 and the upper wall of the cooler chamber 12 is used as the rear end portion of the partition wall, the cooler chamber 12 having a large left-right width and the freezing compartment portion 21 are provided. The cool air smoothly flows into the upper passage 9 having a narrow left and right width disposed behind the rear. Therefore, the pressure loss of the cool air passage 7 can be reduced.
