Can do. Further, since the magnet included in the gasket 44 is easily attracted, when the contact condition is deteriorated due to the deformation or the like, it is possible to further prevent the cold air leakage in the cabinet due to the gap of the gasket contact surface. Moreover, the amount of heat from the heating plate 54 can be efficiently absorbed, and an excessive amount of heat generated by the heating plate 54 can be suppressed, contributing to a reduction in the amount of power consumed by the refrigerator.

また、当板51は周縁を金属にくらべ伝熱能力の低い樹脂製の外郭構成部材52により囲われ、かつ発泡断熱体などの断熱部材55により庫内冷気からの伝熱を受けやすい当板51側面部の断熱能力を高めている。   Further, the abutment plate 51 is surrounded by a resin outer structural member 52 having a lower heat transfer capability than metal, and the abutment plate 51 is easily subjected to heat transfer from the cool air inside the cabinet by a heat insulating member 55 such as a foam heat insulator. The heat insulation capacity of the side is increased.

さらに、外郭構成部材52の側面と空間構成部材60によって構成された熱交換抑制空間59が、外郭構成部材52の側面部に設けられていることで、当板51側面部と貯蔵室間の距離を大きくとることができ、さらに対流のない空間が当板51側面部の断熱能力を高めている。   Further, the heat exchange suppression space 59 configured by the side surface of the outer shell component member 52 and the space component member 60 is provided in the side surface portion of the outer shell member 52, so that the distance between the side surface portion of the plate 51 and the storage chamber is increased. Further, a space without convection enhances the heat insulating ability of the side surface portion of the abutment plate 51.

また、仕切体50の回転軸の中心56は、基本断面で見た場合、熱交換抑制空間59を構成する空間構成部材60の内側に配置することにより、当板51と庫内までの距離を拡大することができ、当板51周囲の断熱性をさらに高めることができる。   Further, the center 56 of the rotating shaft of the partition 50 is arranged inside the space constituting member 60 constituting the heat exchange suppression space 59 when viewed in the basic cross section, thereby reducing the distance between the contact plate 51 and the inside of the cabinet. It is possible to enlarge, and the heat insulation around the plate 51 can be further enhanced.

また、回転軸の中心56は当板51の側面部の外側に位置しており、仕切体50の回転操作性を確保すると共に、当板51の側面部から庫内までの距離を十分に確保することができ、ヒートリーク量の抑制効果をさらに向上させることができる。   Further, the center 56 of the rotating shaft is located outside the side surface portion of the abutment plate 51 to ensure the rotational operability of the partition body 50 and to ensure a sufficient distance from the side surface portion of the abutment plate 51 to the inside of the cabinet. It is possible to further improve the effect of suppressing the amount of heat leak.

空間構成部材60は、仕切体50の回転動作においても冷蔵室扉左38aと接触をしない位置を結んだ線である回転軌跡線に沿った曲面形状をしており、冷蔵室扉左38aの開閉に応じて回転する仕切体50は内面材42と干渉することなく動作を行う。冷蔵室扉左38aを開いた時、前述したように仕切体50は回転軸の中心56を軸として回転を行い所定の位置で回転を停止するが、回転時の勢いにより内面材42と衝突する場合は外郭構成部材52に固着された緩衝材によって衝撃を緩和し衝撃音の抑制を行う。   The space component member 60 has a curved shape along a rotation trajectory line, which is a line connecting positions that do not come into contact with the refrigerator compartment door left 38a even in the rotation operation of the partition 50, and opens and closes the refrigerator compartment door left 38a. Accordingly, the partition member 50 that rotates according to the operation operates without interfering with the inner surface material 42. When the refrigerator door left 38a is opened, as described above, the partition 50 rotates about the center 56 of the rotation shaft and stops rotating at a predetermined position, but collides with the inner surface material 42 due to the momentum during rotation. In this case, the shock is reduced by the cushioning material fixed to the outer structural member 52 and the impact sound is suppressed.

外郭構成部材52の当板51接触部の近傍には基本板厚の薄肉化または切欠き穴で形成した熱伝導抑制部61を設けることで、外気や加熱板54からの熱がまず当板51に伝わり、次に外郭構成部材52に伝わり、外郭構成部材52に伝わった熱が材料内で熱伝導により全体に広がることを抑制し、貯蔵室内空間と熱交換する量を低減し消費電力量の低減に寄与することができる。熱伝導抑制部61は、当板51側面の先端部より貯蔵室側で構成されていることで、当板51からの熱伝導による貯蔵室側への熱侵入をも抑制し、外郭構成部材52と当板51の両方の熱伝導抑制効果を高めることができる。   In the vicinity of the contact portion 51 contact portion of the outer structural member 52, a heat conduction suppressing portion 61 formed by reducing the basic thickness or forming a notch is provided, so that the heat from the outside air or the heating plate 54 is first applied to the contact plate 51. , Then transferred to the outer structural member 52, and the heat transmitted to the outer structural member 52 is prevented from spreading throughout the material due to heat conduction, reducing the amount of heat exchange with the storage space and reducing the amount of power consumption. It can contribute to reduction. The heat conduction suppressing portion 61 is configured on the storage chamber side from the tip of the side surface of the contact plate 51, thereby suppressing heat intrusion to the storage chamber side due to heat conduction from the contact plate 51. And the heat conduction suppressing effect of both of the contact plates 51 can be enhanced.

The cold air circulating through the gap between the partition 50 and the left side of the refrigerator compartment door 38a is shielded by the pivot-side cold air circulation suppressing member 63, whereby heat exchange between the cold air and the outside air via the gasket 44 can be suppressed. Similarly, the heat exchange between the cold air and the outside air via the gasket 44 can be suppressed by shielding the cold air circulating through the gap between the partition 50 and the right side of the refrigerator compartment door 38b by the non-pivot support cold air circulation suppressing member 64. it can.

空間構成部材60は、外郭構成部材52と空間構成部材嵌合部66にて嵌合固定されることにより、組立て時の作業が容易であり、また、固定部材が不要であるため部品点数の削減を行うことができる。   The space component member 60 is fitted and fixed by the outer component member 52 and the space component member fitting portion 66, so that the work at the time of assembly is easy, and the number of components is reduced because the fixing member is unnecessary. It can be performed.

枢支側冷気循環抑制部材63は、空間構成部材60と一体で成形されたことによって、組立て時の作業が不要となり組立て工数の削減を行うことができ、また、枢支側冷気循環抑制部材63の固定に必要な形状が不要であるため熱交換抑制空間59の形状の最大化が可能となり、熱交換抑制空間59の熱交換抑制効果を高めることができる。   The pivot support side cold air circulation suppression member 63 is formed integrally with the space component member 60, so that the assembly work becomes unnecessary and the number of assembling steps can be reduced. Also, the pivot side cold air circulation suppression member 63 is reduced. Since the shape necessary for fixing the heat exchange is not required, the shape of the heat exchange suppression space 59 can be maximized, and the heat exchange suppression effect of the heat exchange suppression space 59 can be enhanced.

また、冷蔵室扉右38bに備えられた湿度センサー68は、仕切体50の当板51正面付近の湿度を感知することで、当板51裏面に貼り付けられた加熱板54の熱量を当板51が結露しない最適な状態に調節することができ、消費電力量の低減を行うことができる。   The humidity sensor 68 provided on the right side of the refrigerator compartment door 38b senses the humidity in the vicinity of the front surface of the abutment plate 51 of the partition 50, thereby determining the amount of heat of the heating plate 54 attached to the back surface of the abutment plate 51. 51 can be adjusted to an optimum state in which condensation does not occur, and power consumption can be reduced.

以上のように、本発明にかかる冷蔵庫は、当板からのヒートリーク量を抑制し冷蔵庫の消費電力能力を向上させることができるため、仕切部材を有する観音開き式の扉装置を備えたあらゆる冷却機器に適用できる。   As mentioned above, since the refrigerator concerning this invention can suppress the amount of heat leaks from this board and can improve the power consumption capability of a refrigerator, all the cooling equipment provided with the double door type door device which has a partition member Applicable to.
