　しかしながら、上記従来の冷蔵庫によると、冷蔵室の背面に配される吐出通路の前面に吐出口が開口するため、吐出口から前方に冷気が吐出される。これにより、冷蔵室内の貯蔵物に直接冷気が当たるため、貯蔵物が乾燥する問題があった。 However, according to the conventional refrigerator, since the discharge port is opened in front of the discharge passage arranged on the back of the refrigerator compartment, cold air is discharged forward from the discharge port. As a result, since the cold is directly applied to the stored item in the refrigerator compartment, there is a problem that the stored item is dried.
　本発明は、貯蔵物の乾燥を低減できる冷蔵庫を提供することを目的とする。 An object of the present invention is to provide a refrigerator capable of reducing the drying of stored items.
　上記目的を達成するために本発明は、貯蔵物を冷却保存する貯蔵室と、冷気を生成する冷却器と、前記貯蔵室の背面から突出して左右方向の中央部に縦方向に延びて配されるとともに前記貯蔵室に冷気を吐出する吐出口を側面に開口する吐出通路と、前記貯蔵室の冷気が流出する戻り口を開口して冷気を前記冷却器に戻す戻り通路と、前記吐出通路の前面に配された熱良導体から成る部材とを備えたことを特徴としている。 In order to achieve the above object, the present invention is provided with a storage room for storing stored items in a cold state, a cooler for generating cool air, and a vertically extending central portion in the left-right direction protruding from the back of the storage room. A discharge passage that opens a discharge port for discharging cool air to the storage chamber on a side surface, a return passage that opens a return port from which the cool air of the storage chamber flows out and returns the cool air to the cooler, and a discharge passage And a member made of a good thermal conductor disposed on the front surface.
　この構成によると、冷却器で生成された冷気は貯蔵室の背面の中央部に突出した吐出通路を流通する。吐出通路を流通する冷気の冷熱は前面に配した熱良導体の部材に伝えられ、冷蔵室に供給される。吐出通路を流通する冷気は側面に開口した吐出口から貯蔵室内に吐出され、貯蔵室の背面及び側面に沿って流通する。貯蔵室を流通した冷気は戻り口から流出し、戻り通路を介して冷却器に戻される。貯蔵室の中央部の貯蔵物は部材から放出される冷熱によって冷却され、両側部の貯蔵物は貯蔵室の背面及び側面に沿って流通する冷気の冷熱により冷却される。 According to this configuration, the cold air generated by the cooler circulates through the discharge passage protruding from the center of the back of the storage chamber. The cold heat of the cold air flowing through the discharge passage is transmitted to a member with a good thermal conductor disposed on the front surface and supplied to the refrigerator compartment. The cold air flowing through the discharge passage is discharged into the storage chamber from the discharge port opened on the side surface, and flows along the back and side surfaces of the storage chamber. The cold air flowing through the storage chamber flows out from the return port and returns to the cooler through the return passage. The storage in the central part of the storage room is cooled by the cold heat released from the member, and the storages on both sides are cooled by the cold heat of the cold air flowing along the back and side surfaces of the storage room.
　また本発明は、上記構成の冷蔵庫において、前記戻り口が前記貯蔵室の下部に配置され、前記吐出口を前記戻り口の上方に配置したことを特徴としている。この構成によると、吐出口から吐出された冷気が自重によって戻り口に導かれる。 Further, according to the present invention, in the refrigerator configured as described above, the return port is disposed at a lower portion of the storage chamber, and the discharge port is disposed above the return port. According to this configuration, the cold air discharged from the discharge port is guided to the return port by its own weight.
　また本発明は、上記構成の冷蔵庫において、前記戻り通路が前記吐出通路の前面に重なり、上方に向かって開口した前記戻り口を介して前記部材が前記戻り通路内に侵入することを特徴としている。この構成によると、戻り口を介して戻り通路に流入した冷気は部材の前面に沿って流通する。これにより、戻り通路を流通する冷気の冷熱が部材に伝えられて貯蔵室に放出される。 In the refrigerator having the above-described configuration, the return passage overlaps the front surface of the discharge passage, and the member enters the return passage through the return opening opened upward. . According to this configuration, the cold air flowing into the return passage through the return port flows along the front surface of the member. Thereby, the cold heat of the cold air flowing through the return passage is transmitted to the member and released into the storage chamber.
　また本発明は、上記構成の冷蔵庫において、正面視において前記吐出通路の延長上に前記冷却器を配置したことを特徴としている。 Further, the present invention is characterized in that in the refrigerator configured as described above, the cooler is disposed on an extension of the discharge passage in a front view.
　本発明によると、貯蔵室の背面の中央部から突出した吐出通路の前面に熱良導体の部材が配され、側面に吐出口が設けられる。これにより、部材から冷熱が放出され、吐出口から吐出された冷気が貯蔵室の背面及び側面に沿って流通する。このため、貯蔵室内の貯蔵物は部材から放出される冷熱及び貯蔵室の背面及び側面に沿う冷気の冷熱によって冷却される。従って、貯蔵物に直接当たる冷気が減少し、貯蔵物の乾燥を低減することができる。 According to the present invention, the heat good conductor member is arranged on the front surface of the discharge passage protruding from the center of the back surface of the storage chamber, and the discharge port is provided on the side surface. Thereby, cold heat is discharged | emitted from a member and the cold air discharged from the discharge outlet distribute | circulates along the back surface and side surface of a storage chamber. For this reason, the stored item in the storage chamber is cooled by the cold heat released from the member and the cold heat of the cold air along the back and side surfaces of the storage chamber. Accordingly, the cool air directly hitting the storage can be reduced, and the drying of the storage can be reduced.

　冷蔵室３の背後にはダンパ１８を介して冷気通路１０に連通する吐出通路２０が設けられる。吐出通路２０は冷蔵室３の左右方向の中央部に縦方向に延びて配され、冷蔵室３の背面板３ａに対して突出して形成される。また、正面視において吐出通路２０の延長上に冷却器１１が配置される。冷蔵室３の下部には上面に戻り口３１を開口した戻り通路３０が形成される。戻り通路３０は冷却器１１の上流側の冷気通路１０に連結される。 A discharge passage 20 that communicates with the cold air passage 10 through a damper 18 is provided behind the refrigerator compartment 3. The discharge passage 20 extends in the vertical direction at the center in the left-right direction of the refrigerating chamber 3 and is formed so as to protrude from the back plate 3 a of the refrigerating chamber 3. In addition, the cooler 11 is disposed on the extension of the discharge passage 20 in a front view. In the lower part of the refrigerator compartment 3, a return passage 30 having a return opening 31 is formed on the upper surface. The return passage 30 is connected to the cold air passage 10 on the upstream side of the cooler 11.
　図３は図１のＡ－Ａ断面図を示している。冷蔵室３の背面板３ａ上には発泡スチロール等の断熱材により形成されたダクトパネル２１が配される。ダクトパネル２１は樹脂成形品の保持パネル２３により保持され、保持パネル２３に設けた係合爪（不図示）が背面板３ａに係合する。これにより、ダクトパネル２１が背面板３ａに取り付けられ、ダクトパネル２１の背面に凹設された溝によって吐出通路２０が形成される。ダクトパネル２１の側壁２１ａは吐出通路２０の側面を形成し、冷気の吐出口２４が開口する。 FIG. 3 is a cross-sectional view taken along the line AA in FIG. On the back plate 3a of the refrigerator compartment 3, a duct panel 21 formed of a heat insulating material such as polystyrene foam is disposed. The duct panel 21 is held by a holding panel 23 of a resin molded product, and an engaging claw (not shown) provided on the holding panel 23 engages with the back plate 3a. As a result, the duct panel 21 is attached to the back plate 3a, and the discharge passage 20 is formed by a groove recessed in the back surface of the duct panel 21. The side wall 21a of the duct panel 21 forms the side surface of the discharge passage 20, and the cool air discharge port 24 is opened.
　吐出口２４は各設置部６（図２参照）間にそれぞれ配される。これにより、トレイを所望の位置に設置した際にトレイによって仕切られた各区画内に冷気を吐出することができる。従って、トレイ上に載置された貯蔵物を確実に冷却することができる。尚、隔離室８（図１参照）には吐出口２４が設けられていない。 The discharge port 24 is arranged between each installation part 6 (refer FIG. 2), respectively. Thereby, when the tray is installed at a desired position, cold air can be discharged into each section partitioned by the tray. Therefore, the stored items placed on the tray can be reliably cooled. Note that the discharge port 24 is not provided in the isolation chamber 8 (see FIG. 1).
　ダクトパネル２１の前面には金属（例えば、ステンレスやアルミニウム）等の熱良導体により形成された部材２２が配される。部材２２は保持パネル２３に設けた溝部２３ａに係合して取り付けられる。縦方向に延びた部材２２によって吐出通路２０の前面が覆われる。これにより、吐出通路２０を流通する冷気の冷熱がダクトパネル２１を介して部材２２に伝えられ、冷蔵室３に放出される。 A member 22 formed of a good heat conductor such as metal (for example, stainless steel or aluminum) is disposed on the front surface of the duct panel 21. The member 22 is attached by engaging with a groove 23 a provided in the holding panel 23. The front surface of the discharge passage 20 is covered by the member 22 extending in the vertical direction. Thereby, the cold heat of the cold air flowing through the discharge passage 20 is transmitted to the member 22 through the duct panel 21 and released to the refrigerator compartment 3.
　図４は図１のＢ－Ｂ断面図を示している。戻り通路３０（図１参照）は吐出通路２０の下部の前面に重なり、隔離室８（図１参照）内に配される戻り口３１が上方に面して開口する。戻り口３１には異物の侵入を防止するためにグリル３１ａが形成される。また、部材２２は上方から戻り口３１を介して戻り通路３０内に侵入し、戻り通路３０を部材２２の前面に沿って流通する冷気と接触する。これにより、戻り通路３０を流通する冷気の冷熱が部材２２に伝えられる。 FIG. 4 shows a BB cross-sectional view of FIG. The return passage 30 (see FIG. 1) overlaps with the lower front surface of the discharge passage 20, and a return port 31 arranged in the isolation chamber 8 (see FIG. 1) opens upward. A grill 31a is formed at the return port 31 in order to prevent entry of foreign matter. Further, the member 22 enters the return passage 30 from above through the return port 31, and comes into contact with the cold air flowing along the front surface of the member 22 through the return passage 30. Thereby, the cold heat of the cold air flowing through the return passage 30 is transmitted to the member 22.
　上記構成の冷蔵庫１において、ファン１２が駆動されると冷却器１１により生成された冷気は冷気通路１０を流通して吐出口１４、１５から冷凍室４の上部に吐出される。冷凍室４に吐出された冷気は冷凍室４内を流通し、下部の戻り口１６から流出して冷却器１１に戻される。これにより、冷凍室４内の貯蔵物が冷却される。 In the refrigerator 1 configured as described above, when the fan 12 is driven, the cold air generated by the cooler 11 flows through the cold air passage 10 and is discharged from the discharge ports 14 and 15 to the upper portion of the freezer compartment 4. The cold air discharged into the freezer compartment 4 flows through the freezer compartment 4, flows out from the lower return port 16, and is returned to the cooler 11. Thereby, the stored thing in the freezer compartment 4 is cooled.
　ダンパ１８が開かれると、冷気通路１０を流通する冷気の一部が吐出通路２０に導かれる。吐出通路２０を流通する冷気は側面に設けた吐出口２４から矢印Ｄ１（図３参照）に示すように側方に吐出される。吐出口２４から吐出された冷気は自重により降下しながら、冷蔵室３の背面板３ａに沿って左右方向に流通して冷蔵室３の側壁３ｂに沿って前方に流通する。 When the damper 18 is opened, a part of the cold air flowing through the cold air passage 10 is guided to the discharge passage 20. The cold air flowing through the discharge passage 20 is discharged to the side as indicated by an arrow D1 (see FIG. 3) from a discharge port 24 provided on the side surface. The cold air discharged from the discharge port 24 flows in the left-right direction along the back plate 3a of the refrigerator compartment 3 while descending by its own weight, and flows forward along the side wall 3b of the refrigerator compartment 3.
　そして、該冷気は前方から隔離室８に流入し、収納ケース８ａの周囲を流通して矢印Ｄ２（図２参照）に示すように左右方向の中央部の戻り口３１から流出する。戻り口３１から流出した冷気は戻り通路３０を流通し、冷却器１１に戻される。 Then, the cold air flows into the isolation chamber 8 from the front, flows around the storage case 8a, and flows out from the return port 31 at the center in the left-right direction as shown by the arrow D2 (see FIG. 2). The cold air flowing out from the return port 31 flows through the return passage 30 and is returned to the cooler 11.
　また、吐出通路２０及び戻り通路３０を流通する冷気の冷熱は部材２２に伝えられ、矢印Ｅ（図３参照）に示すように冷蔵室３内に放出される。 Further, the cold heat of the cold air flowing through the discharge passage 20 and the return passage 30 is transmitted to the member 22 and released into the refrigerator compartment 3 as shown by an arrow E (see FIG. 3).
　冷蔵室３内の左右方向の中央部に配された貯蔵物は部材２２から放出される冷熱によって冷却される。冷蔵室３内の両側部の貯蔵物は背面板３ａ及び側壁３ｂに沿って流通する冷気の冷熱により冷却される。これにより、貯蔵物を冷熱によって周囲から間接的に冷却することができる。 The stored item arranged in the center in the left-right direction in the refrigerator compartment 3 is cooled by the cold heat released from the member 22. The stored items on both sides in the refrigerator compartment 3 are cooled by the cold heat of the cold air flowing along the back plate 3a and the side wall 3b. Thereby, a store thing can be indirectly cooled from the surroundings with cold heat.
　本実施形態によると、冷蔵室３の背面の中央部から突出した吐出通路２０の前面に熱良導体の部材２２が配され、側面に吐出口２４が設けられる。これにより、部材２２から冷熱が放出され、吐出口２４から吐出された冷気が冷蔵室３の背面及び側面に沿って流通する。このため、冷蔵室３内の貯蔵物は部材２２から放出される冷熱及び背面及び側面に沿う冷気の冷熱によって冷却される。従って、貯蔵物に直接当たる冷気が減少し、貯蔵物の乾燥を低減することができる。 According to the present embodiment, the heat good conductor member 22 is disposed on the front surface of the discharge passage 20 protruding from the center of the back surface of the refrigerator compartment 3, and the discharge port 24 is provided on the side surface. Thereby, the cold heat is released from the member 22, and the cold air discharged from the discharge port 24 flows along the back surface and the side surface of the refrigerator compartment 3. For this reason, the stored item in the refrigerator compartment 3 is cooled by the cold heat released from the member 22 and the cold air along the back and side surfaces. Accordingly, the cool air directly hitting the storage can be reduced, and the drying of the storage can be reduced.
　また、吐出通路２０が左右方向の中央部に配されるため、吐出通路２０の水平断面の断面積を流量に応じて確保した際に水平断面のアスペクト比が１に近づけられる。これにより、吐出通路２０の圧力損失を低減して冷蔵庫１の省エネルギー化を図ることができる。 In addition, since the discharge passage 20 is arranged in the central portion in the left-right direction, the aspect ratio of the horizontal cross section can be made close to 1 when the horizontal cross-sectional area of the discharge passage 20 is secured according to the flow rate. Thereby, the pressure loss of the discharge passage 20 can be reduced and energy saving of the refrigerator 1 can be achieved.
　また、戻り口３１が冷蔵室３の下部に配置され、吐出口２４を戻り口３１の上方に配置したので、吐出口２４から吐出された冷気が自重によって戻り口３１に導かれる。従って、ファン１２の送風効率を向上させることができる。 Further, since the return port 31 is disposed at the lower part of the refrigerator compartment 3 and the discharge port 24 is disposed above the return port 31, the cold air discharged from the discharge port 24 is guided to the return port 31 by its own weight. Therefore, the blowing efficiency of the fan 12 can be improved.
　また、戻り通路３０が吐出通路２０の前面に重なり、上方に向かって開口した戻り口３１を介して部材２２が戻り通路３０内に侵入するので、戻り通路３０を流通する冷気の冷熱が部材２２に伝えられて冷蔵室３に放出される。従って、冷蔵庫１の冷却効率をより向上することができる。 Further, since the return passage 30 overlaps the front surface of the discharge passage 20 and the member 22 enters the return passage 30 via the return port 31 opened upward, the cold heat of the cold air flowing through the return passage 30 is increased. To be released into the refrigerator compartment 3. Therefore, the cooling efficiency of the refrigerator 1 can be further improved.
　また、正面視において吐出通路２０の延長上に冷却器１１を配置したので、冷却器１１から冷気通路１０及び吐出通路２０を左右方向に屈曲させずに吐出口２４に冷気を導くことができる。従って、吐出通路２０の圧力損失をより低減することができる。 Further, since the cooler 11 is disposed on the extension of the discharge passage 20 in a front view, the cool air can be guided from the cooler 11 to the discharge port 24 without bending the cool air passage 10 and the discharge passage 20 in the left-right direction. Therefore, the pressure loss of the discharge passage 20 can be further reduced.
　本発明によると、吐出口を開口する冷気の吐出通路を貯蔵室の背面に配した冷蔵庫に利用することができる。 According to the present invention, it can be used for a refrigerator in which a discharge passage for cold air that opens a discharge port is arranged on the back of a storage room.
