第一扉121Aと第二扉121Bを閉じているとき、冷蔵庫内と庫外はガスケット140によってシールされるので、侵入熱は低減される。 When closing the first door 121A and the second door 121B, the refrigerator and the outside-compartment because it is sealed by a gasket 140, heat invasion is reduced. また仕切り体150の内部はウレタン樹脂156が充填されているので、金属板150aが外気に触れ、また金属板150aの裏面に貼付された金属板150a表面の結露防止するヒータなどの熱源181が通電されたときでも、仕切り体150内部を熱伝導して冷蔵室105内部への熱侵入を低減することができる。 Since the inside of the partition member 150 a urethane resin 156 is filled, the metal plate 150a is touched to the outside air, and a heat source 181 such as a heater to prevent condensation of the patch metal plate 150a surface to the back surface of the metal plate 150a is energized have been in time, it is possible to the interior partition 150 to reduce the heat penetration into the interior refrigerating compartment 105 by thermal conduction.

さらに仕切り体150の製造時、あらかじめ第2区画部173bにスチロール材などの断熱材が挿入され、そのあと2箇所の注入孔170から液状のウレタン樹脂が第1区画部173aに充填される。 Furthermore during the production of the partitioning member 150, the heat insulating material is inserted, such as pre-styrol material in the second compartment portion 173b, a urethane resin liquid from the injection hole 170 of the later two places is charged into the first compartment portion 173a. 充填されたウレタン樹脂は第1区画部173a内を流動し、第1区画部173aの両端部に設けた空気抜き孔171から外部へ意図的にウレタン樹脂を漏れ出させることで、第1区画部173a内を隅々まで充填できたことを目視で確認することができ、空隙が発生するのを防止することができる。 Filled urethane resin flows through the first compartment portion 173a, a deliberately causing leak urethane resin from the air vent hole 171 provided at the both end portions of the first partition portion 173a to the outside, the first partition portion 173a inner can be visually confirmed that could fill every corner of the can voids can be prevented.

したがって仕切り体150の主となる第1区画部173aの断熱性を高めることができ、金属板150aや熱源181の熱が仕切り体150内を伝わって冷蔵室105内へ侵入するのを低減することができる。 Therefore it is possible to enhance the heat insulating property of the first partition portion 173a as a main partition member 150, the heat of the metal plate 150a and the heat source 181 to reduce the ingress and transmitted to the partition body 150 into the refrigerator compartment 105 can.

また仕切り体150は第2扉121Bの開閉によってヒンジ部材160とバネ部材161によって回転する。 The partition body 150 is rotated by a hinge member 160 and the spring member 161 by opening and closing the second door 121B. 特に扉を開放したとき、図5の矢印のように仕切り体150が回転する。 Especially when opening the door, the partition member 150 as indicated by the arrows in FIG. 5 is rotated. このとき扉内板135に仕切り体背面部材150cが当るかわりに緩衝材174が扉内板135に当るように厚みを持たせているので、衝突音を低減でき、さらに、緩衝材174はウレタン発泡後、注入孔170、空気抜き孔171を塞ぎ内部への吸湿を防止できる。 Since the cushioning material 174 instead of hitting the partition body back member 150c in the door inner plate 135 at this time is slightly thickened to hit the door inner plate 135, can be reduced impact noise, further, the cushioning material 174 is foamed urethane after, the injection hole 170, the moisture to the interior block the air vent hole 171 can be prevented. また位置決めのために凹部172を形成しているので、緩衝材174の貼付バラツキを低減し、信頼性を確保することができる。 Since forming the concave portions 172 for positioning, it is possible to reduce sticking variation of the buffer material 174, to secure the reliability.

以上のように本発明にかかる冷蔵庫は、仕切り体の大部分を発泡ウレタン樹脂にて構成することにより、庫外の高温空気から庫内への熱侵入を抑制し、冷蔵庫の消費電力量を低減することができるので仕切り体を構成する業務用冷蔵庫にも適用できる。 Refrigerator according to the present invention, as described above, by configuring the majority of the partitioning member in urethane foam resin, suppressing heat invasion into the compartment from the compartment outside of the hot air, reducing the power consumption of the refrigerator it can also be applied to commercial refrigerator that make up the partition body since it is possible to.
