In addition, at the rear of the freezing space 40, a freezing cooler 54 that cools the air in the freezing space 40, and the cold air cooled by the freezing cooler 54 is supplied to the ice making room, the first freezing room 44, and the second freezing room. A freezing fan 55 for blowing air is provided. The refrigeration cooler 52 and the refrigeration cooler 54 constitute a refrigeration cycle together with the compressor 32, a condenser (not shown), and a switching valve (not shown), and are cooled by the refrigerant discharged from the compressor 32.

図１〜図３に示すように、冷蔵室２２の背面には、冷蔵室２２の下端から上端にかけて背面ダクト６０が設けられている。冷蔵用ファン５３の回転により冷蔵用冷却器５２で冷却された冷気は、背面ダクト６０の下端から上端へ上方に向けて流れ込み、吹出口６６及び間隙６４から冷蔵室２２内へ吹き出す。   As shown in FIGS. 1 to 3, a rear duct 60 is provided on the rear surface of the refrigerator compartment 22 from the lower end to the upper end of the refrigerator compartment 22. The cold air cooled by the refrigeration cooler 52 by the rotation of the refrigeration fan 53 flows upward from the lower end of the rear duct 60 to the upper end, and blows out into the refrigeration chamber 22 from the outlet 66 and the gap 64.

背面ダクト６０は、冷蔵室２２における内箱１２ｂの背面１２ｂ１とこの内箱１２ｂの背面１２ｂ１に対向して取り付けられたダクト形成材６２とで挟まれた空間に設けられている。ダクト形成材６２の上端縁は、内箱１２ｂの背面上端部と所定の冷気吹き出し用の間隙６４を設けるように設置されている。   The rear duct 60 is provided in a space sandwiched between the rear surface 12b1 of the inner box 12b and the duct forming member 62 attached to the rear surface 12b1 of the inner box 12b in the refrigerator compartment 22. The upper end edge of the duct forming material 62 is installed so as to provide a predetermined cool air blowing gap 64 from the rear upper end portion of the inner box 12b.

ダクト形成材６２は、図３〜図５に示すように、例えば合成樹脂を射出成形した概略平板状をなしており、板状に設けられ冷蔵室２２の背面ほぼ全域を覆うように配設され背面ダクト６０の前面部分を区画形成する板部６１と、この板部６１の裏面側に取り付けられる吹出部材６３とを備える。ダクト形成材６２の板部６１には吹出口６６（必要に応じて、６６ａ、６６ｂ、６６ｃと示す）が形成され、吹出部材６３にはリブ６８、ガイド部７２、及び突起７０（必要に応じて、７０ａ、７０ｂ、７０ｃと示す）が一体に形成されている。吹出部材６３は吹出口６６を覆うように板部６１の裏面側に取り付けられ、板部６１と吹出部材６３との間に背面ダクト６０の上流側（つまり、下方）に向けて開口する冷気取込口６５（必要に応じて、６５ａ、６５ｂ、６５ｃと示す）が形成されている。   As shown in FIGS. 3 to 5, the duct forming material 62 has, for example, a substantially flat plate shape obtained by injection molding synthetic resin, and is provided in a plate shape so as to cover almost the entire rear surface of the refrigerator compartment 22. The board part 61 which divides and forms the front-surface part of the back surface duct 60, and the blowing member 63 attached to the back surface side of this board part 61 are provided. An air outlet 66 (shown as 66a, 66b, 66c, if necessary) is formed in the plate portion 61 of the duct forming material 62, and a rib 68, a guide portion 72, and a protrusion 70 (if necessary) are formed on the air blowing member 63. 70a, 70b, and 70c) are integrally formed. The blow-out member 63 is attached to the back surface side of the plate portion 61 so as to cover the blow-out port 66, and cool air opening that opens toward the upstream side (that is, downward) of the back duct 60 between the plate portion 61 and the blow-out member 63. A slot 65 (shown as 65a, 65b, 65c as required) is formed.

詳細には、吹出口６６は、ダクト形成材６２の板部６１を前後に貫通して設けられ、背面ダクト６０を流通する冷気を冷蔵室２２に導入する開口であり、冷蔵庫１０の幅方向に延びる長円状に設けられている。吹出口６６は、背面ダクト６０の上流側から下流側に沿って（つまり、上下方向に沿って）複数個（例えば、３個）間隔をあけてダクト形成材６２に設けられている。   Specifically, the air outlet 66 is provided through the plate portion 61 of the duct forming material 62 in the front-rear direction, and is an opening that introduces cold air flowing through the rear duct 60 into the refrigerator compartment 22, and extends in the width direction of the refrigerator 10. It is provided in an elongated oval shape. A plurality of (for example, three) air outlets 66 are provided in the duct forming material 62 from the upstream side to the downstream side of the rear duct 60 (that is, along the vertical direction) at intervals.

リブ６８は、吹出口６６の上縁部に沿ってダクト形成材６２の裏面から背面ダクト６０に向けて突出形成されており、背面ダクト６０を流通する冷気の一部を堰き止めて、リブ６８の下側に位置する吹出口６６へ堰き止めた冷気を送り出す。図５に示すように、リブ６８の左右の両側には、側方に行くほど下方へ傾斜するガイド部７２がリブ６８に連続して設けられている。   The rib 68 protrudes from the back surface of the duct forming material 62 toward the back duct 60 along the upper edge of the air outlet 66, and blocks a part of the cold air flowing through the back duct 60. The cold air dammed up is sent to the air outlet 66 located on the lower side. As shown in FIG. 5, on both the left and right sides of the rib 68, guide portions 72 that are inclined downward toward the side are provided continuously to the rib 68.

突起７０は、冷蔵庫１０の幅方向に沿って延びる突条であり、背面ダクト６０から吹出口６６に向けて（つまり、前方に向けて）突出し、吹出口６６の位置において終端するように形成されている。   The protrusion 70 is a protrusion extending along the width direction of the refrigerator 10, and is formed so as to protrude from the rear duct 60 toward the outlet 66 (that is, toward the front) and terminate at the position of the outlet 66. ing.

背面ダクト６０の上流側に位置する突起７０の下面は、前方に行くほど上方への傾きが緩やかになるような曲面状の上流側ガイド面７４に設けられ、背面ダクト６０の下流側に位置する突起７０の上面は、前方に行くほど下方への傾きが緩やかになるような曲面状の下流側ガイド面に設けられている。これにより、突起７０は上下方向に沿った断面形状が、前方に行くほど上下方向の幅寸法が狭くなるような形状をなしている。   The lower surface of the protrusion 70 located on the upstream side of the rear duct 60 is provided on a curved upstream guide surface 74 that is inclined upward as it goes forward, and is located on the downstream side of the rear duct 60. The upper surface of the protrusion 70 is provided on a curved downstream guide surface whose downward inclination becomes gentler toward the front. Thus, the protrusion 70 has a cross-sectional shape along the vertical direction such that the width dimension in the vertical direction becomes narrower toward the front.

突起７０に設けられた上流側ガイド面７４は、これに衝突した背面ダクト６０の上流側から下流側へ流通する冷気を前方に指向させ吹出口６６を通して冷蔵室２２内へ吹き出させる。一方、突起７０に設けられた下流側ガイド面７６は、リブ６８によって遮られた背面ダクト６０を流通する冷気を前方に指向させ吹出口６６を通して冷蔵室２２内へ吹き出させる。   The upstream guide surface 74 provided on the protrusion 70 directs the cold air flowing from the upstream side to the downstream side of the rear duct 60 that collides with the forward guide surface 74 and blows it out into the refrigerator compartment 22 through the outlet 66. On the other hand, the downstream guide surface 76 provided on the projection 70 directs the cold air flowing through the back duct 60 blocked by the rib 68 forward and blows it out into the refrigerating chamber 22 through the air outlet 66.

なお、背面ダクト６０の最も上流側に設けられた吹出口６６ａに向けて突出する突起７０ａの突出量は、吹出口６６ａより背面ダクト６０の下流側に設けられた吹出口６６ｂ、６６ｃに向けて突出する突起７０ｂ，７０ｃの突出量に比べて小さく設定され、吹出口６６ａと上流側ガイド面７４との間（つまり、背面ダクト６０の上流側に位置する冷気取込口６５ａ）の冷蔵庫前後方向の間隔Ａが、吹出口６６ｂ，６６ｃと上流側ガイド面７４との間（つまり、冷気取込口６５ａより背面ダクト６０の下流側に位置する冷気取込口６５ｂ、６５ｃ）の冷蔵庫前後方向の間隔Ｂ，Ｃに比べて小さく設けられている。   In addition, the protrusion amount of the protrusion 70a which protrudes toward the blower outlet 66a provided at the most upstream side of the rear duct 60 is directed toward the blower outlets 66b and 66c provided at the downstream side of the rear duct 60 from the blower outlet 66a. The front-rear direction of the refrigerator is set smaller than the protruding amount of the protruding protrusions 70b and 70c, and is between the outlet 66a and the upstream guide surface 74 (that is, the cold air intake 65a located on the upstream side of the rear duct 60). Between the air outlets 66b and 66c and the upstream guide surface 74 (that is, the cold air intake ports 65b and 65c located on the downstream side of the rear duct 60 from the cold air intake port 65a) in the front-rear direction of the refrigerator. It is smaller than the distances B and C.

上記のような本実施形態の冷蔵庫１０では、図２及び図３に示すように、冷蔵用ファン５３の動作により背面ダクト６０内に流入した冷蔵用冷却器５２で冷却された冷気の一部が、板部６１と吹出部材６３との間に形成された冷気取込口６５に流れ込む。   In the refrigerator 10 of this embodiment as described above, as shown in FIGS. 2 and 3, a part of the cold air cooled by the refrigeration cooler 52 that has flowed into the rear duct 60 by the operation of the refrigeration fan 53 is obtained. Then, the air flows into a cold air inlet 65 formed between the plate portion 61 and the blowing member 63.

冷気取込口６５から吹出部材６３内に流れ込んだ冷気は、上流側ガイド面７４に衝突して前方に指向されるものと、ガイド部７２によってリブ６８と下流側ガイド面７６との間に案内され、下流側ガイド面７６に衝突して前方に指向されるものとに分流された後、分流された冷気が吹出口６６において合流されて吹き出される。このように、上流側ガイド面７４に衝突して前方に指向された冷気と、下流側ガイド面７６に衝突して前方に指向された冷気とが、１つの吹出口６６から吹き出される。そのため、上流側ガイド面７４によって指向された冷気と下流側ガイド面７６によって指向された冷気との上下方向成分を互いに打ち消すことができ、吹出口６６から吹き出される冷気の直進性が良く、冷蔵室２２内に収納された貯蔵品の冷却効率を向上させることができる。   The cold air that has flowed into the blowing member 63 from the cold air inlet 65 collides with the upstream guide surface 74 and is directed forward, and is guided between the rib 68 and the downstream guide surface 76 by the guide portion 72. Then, after colliding with the downstream guide surface 76 and being diverted to be directed forward, the diverted cold air is merged and blown out at the outlet 66. In this way, the cool air directed forward by colliding with the upstream guide surface 74 and the cool air directed forward by colliding with the downstream guide surface 76 are blown out from one air outlet 66. Therefore, the vertical components of the cold air directed by the upstream guide surface 74 and the cold air directed by the downstream guide surface 76 can be canceled each other, and the straightness of the cold air blown from the air outlet 66 is good, and the refrigerator is refrigerated. The cooling efficiency of the stored item stored in the chamber 22 can be improved.

また、本実施形態の冷蔵庫１０では、背面ダクト６０の上流側から下流側に沿って複数個設けられた吹出口６６のうち、最も背面ダクト６０の上流側に設けられた吹出口６６ａと上流側ガイド面７４との間の間隔Ａが、それより下流側に設けられた吹出口６６ｂ，６６ｃと上流側ガイド面７４との間の間隔Ｂ，Ｃに比べて小さく設けられている。そのため、冷気の流れの速い背面ダクト６０の上流側では下流側に比べて冷気取込口６５を設けることができ、複数設けられた吹出口６６からの冷気の吹出量を均一にして冷蔵室２２を均一に冷却することができる。   Moreover, in the refrigerator 10 of this embodiment, the air outlet 66a provided in the most upstream side of the back surface duct 60 among the air outlets 66 provided in a plurality along the downstream side from the upstream side of the back surface duct 60 and the upstream side. The distance A between the guide surface 74 is smaller than the distances B and C between the air outlets 66b and 66c provided on the downstream side and the upstream side guide surface 74. Therefore, the cold air intake port 65 can be provided on the upstream side of the rear duct 60 where the flow of cold air is fast compared to the downstream side, and the amount of cold air blown from the plurality of air outlets 66 is made uniform, so that the refrigerator compartment 22 is provided. Can be cooled uniformly.
