（本開示の基礎となった知見等）
図１５は、特許文献１に開示された従来の冷蔵庫の要部斜視図である。図１５において、発泡ウレタンを充填発泡し製造する従来の冷蔵庫の回転扉において、縁枠底辺部１５２に取り付けた補強金属１５１に、側辺補強金属１５６をオーバーラップさせることで強度の向上と、回転扉の脱落リスクの低減を図っていた。 (Knowledge, etc. that was the basis of this disclosure)
FIG. 15 is a perspective view of a main part of a conventional refrigerator disclosed in Patent Document 1. In FIG. 15, in a revolving door of a conventional refrigerator filled and foamed with urethane foam, the strength is improved and rotation is achieved by overlapping the side reinforcing metal 156 with the reinforcing metal 151 attached to the bottom edge portion 152 of the edge frame. The risk of the door falling off was reduced.

また、従来の発泡ウレタンを充填発泡し製造する冷蔵庫の回転扉において、第一の補強部１５１ａと第二の補強部１５１ｂを有する補強金属１５１を縁枠底辺部１５２に締結手段１５３で取り付け、縁枠側辺部１５４に固定手段１５５で取付けた側辺補強金属１５６とオーバーラップさせ、回転扉の内部空間にウレタンを充填していた。加えて、補強金属１５１の穴部にヒンジ受け１５７を設け、第二の補強部１５１ｂで包むことで、強度向上と脱落防止を図っていた。 Further, in the revolving door of a conventional refrigerator filled and foamed with urethane foam, a reinforcing metal 151 having a first reinforcing portion 151a and a second reinforcing portion 151b is attached to the bottom edge portion 152 of the edge frame by fastening means 153, and the edge is attached. The frame side side portion 154 was overlapped with the side side reinforcing metal 156 attached by the fixing means 155, and the internal space of the revolving door was filled with urethane. In addition, a hinge receiver 157 is provided in the hole of the reinforcing metal 151 and wrapped with the second reinforcing portion 151b to improve the strength and prevent the metal from falling off.

また、近年、更なる省エネルギー化を図るために、回転扉内部の発泡ウレタンを廃止し、発泡ウレタンより断熱性能が優れた真空断熱材のみで構成する回転扉を有する冷蔵庫も提案されている（例えば、特許文献２参照）。 Further, in recent years, in order to further save energy, a refrigerator having a rotating door composed of only a vacuum heat insulating material having better heat insulating performance than urethane foam has been proposed by abolishing urethane foam inside the rotating door (for example). , Patent Document 2).

真空断熱材のみで構成された回転扉のヒンジ部は、ヒンジ周辺の真空断熱材を面取りして生じた空間に、ヒンジとＬ字の補強金属を設けるものである。 The hinge portion of the rotary door made of only the vacuum heat insulating material is provided with the hinge and the L-shaped reinforcing metal in the space created by chamfering the vacuum heat insulating material around the hinge.

しかしながら、特許文献２に記載されたような冷蔵庫の回転扉を真空断熱材のみで構成した場合、発泡ウレタンの充填発泡によるヒンジ部を補強する効果が失われ、ヒンジ部の強度を確保することが困難になるという課題があった。 However, when the rotating door of the refrigerator as described in Patent Document 2 is composed only of the vacuum heat insulating material, the effect of reinforcing the hinge portion by filling and foaming the urethane foam is lost, and the strength of the hinge portion can be ensured. There was a problem that it became difficult.

また、真空断熱材の破袋を防ぎつつ、断熱性能を確保するためにヒンジ部の構成部品は小さくする必要がある。そこで、Ｌ字の補強金属を配置し、扉の脱落を防いでいるが、平面に設けた貫通孔ではヒンジが破損したときに扉が脱落するリスクがあった。 Further, it is necessary to make the components of the hinge portion small in order to secure the heat insulating performance while preventing the vacuum heat insulating material from breaking. Therefore, an L-shaped reinforcing metal is arranged to prevent the door from falling off, but there is a risk that the door will fall off when the hinge is damaged in the through hole provided on the flat surface.

発明者らは、以上のような課題があることを発見し、その課題を解決するために、本開示の主題を構成するに至った。 The inventors have discovered that there is a problem as described above, and have come to construct the subject matter of the present disclosure in order to solve the problem.

そこで、本開示は、ヒンジ強度を向上させ、扉が脱落するリスクを低減し、さらに断熱性能が向上し、省エネ性能が向上する冷蔵庫を提供する。 Therefore, the present disclosure provides a refrigerator in which the hinge strength is improved, the risk of the door falling off is reduced, the heat insulating performance is further improved, and the energy saving performance is improved.

また、縁枠部３４と真空断熱材３５を確実に接合するために、例えば図６Ａ、６Ｂのように、縁枠部３４の縁枠左側辺部３４ｃや、縁枠右側辺部３４ｄを２つの樹脂部品から構成しても良い。縁枠部３４の外観面６１をなす外観縁枠部品６２と、真空断熱材３５との接合面６３をなす接合縁枠部品６４を、嵌合部６５によって嵌合させて構成することで、縁枠部３４は外観の設計自由度を保ちつつ、確実に真空断熱材３５と接合できる。 Further, in order to securely join the edge frame portion 34 and the vacuum heat insulating material 35, for example, as shown in FIGS. 6A and 6B, two edge frame left side portions 34c and an edge frame right side side portion 34d are attached. It may be composed of resin parts. The edge is formed by fitting the exterior edge frame component 62 forming the exterior surface 61 of the edge frame portion 34 and the joint edge frame component 64 forming the joint surface 63 with the vacuum heat insulating material 35 by the fitting portion 65.

The upper hinge bearing 91 may be formed of a component using a resin such as polyacetal having excellent slidability, or a bearing portion (not shown) may be formed in the component of the edge frame portion 34.

また、上ヒンジ軸受け９１は、縁枠上辺部３４ａと縁枠左側辺部３４ｃに固定される補強金属９２に備える穴部９２ａを貫通する構成とすることで、上部扉ヒンジ３６が破損して断熱扉筐体２１が脱落するリスクを軽減できる。 Further, the upper hinge bearing 91 is configured to penetrate the hole portion 92a provided in the reinforcing metal 92 fixed to the edge frame upper side portion 34a and the edge frame left side side portion 34c, so that the upper door hinge 36 is damaged and heat-insulated.

回転規制部材１０２は、回転扉１７ａが所定の角度以上に開かないように、所定角度以上になると回転規制部材１０２が、下ヒンジ２４に設けられた回転規制部材接触部２４ｂに接触することにより、回転が規制される。縁枠底辺部３４ｂには、凸形状１０６が設けられており、補強金属１０５の縁枠嵌合部１０５ａと嵌合する。加えて、補強金属１０５の側辺側締結部１０５ｂは、側辺側締結手段１０７を用いて、側辺補強金属６６と締結される。 When the rotation restricting member 102 reaches a predetermined angle or more so that the revolving door 17a does not open more than a predetermined angle, the rotation regulating member 102 comes into contact with the rotation regulating member contact portion 24b provided on the lower hinge 24.

［１−２．動作］
以上のように構成された実施の形態１の冷蔵庫について、以下その動作、作用を説明する。 [1-2. motion]
The operation and operation of the refrigerator of the first embodiment configured as described above will be described below.

まず、断熱扉筐体２１は、内部に備える真空断熱材３５に、断熱扉筐体２１の外殻部品３１（内板部３２、前板部３３、縁枠部３４）が接合されることによって一体化され、断熱扉筐体２１として構成される。真空断熱材３５の被覆材７２は、外殻部品３１に接合された際に外殻部品３１の内面に接合可能な形状に成形されることにより、断熱扉筐体２１の内部空間の真空断熱材３５の比率が高まり、断熱性能が向上する。 First, the heat insulating door housing 21 is formed by joining the outer shell parts 31 (inner plate portion 32, front plate portion 33, edge frame portion 34) of the heat insulating door housing 21 to the vacuum heat insulating material 35 provided inside. It is integrated and configured as the heat insulating door housing 21. The covering material 72 of the vacuum heat insulating material 35 is formed into a shape that can be joined to the inner surface of the outer shell component 31 when it is joined to the outer shell component 31, so that the vacuum heat insulating material in the internal space of the heat insulating door housing 21 is formed. The ratio of 35 is increased, and the heat insulating performance is improved.

断熱扉筐体２１の外殻部品３１は、真空断熱材３５を保護する役割を有し、真空断熱材３５が破袋することを防ぐ。加えて、断熱扉１７の強度を保つ、構造部品としての役割を持つ。断熱扉筐体２１は、縁枠部３４の上ヒンジ２３、下ヒンジ２４を通して、冷蔵庫本体１１と連結され、冷蔵庫本体１１に回転自在に連結される。また、食品ポケット２６を備える為、重量が大きくなり、上ヒンジ２３、下ヒンジ２４に大きな負荷が生じる。特に、荷重が負荷される下部扉ヒンジ３７の強度は重要となる。 The outer shell component 31 of the heat insulating door housing 21 has a role of protecting the vacuum heat insulating material 35 and prevents the vacuum heat insulating material 35 from breaking. In addition, it has a role as a structural component that maintains the strength of the heat insulating door 17. The heat insulating door housing 21 is connected to the refrigerator main body 11 through the upper hinge 23 and the lower hinge 24 of the edge frame portion 34, and is rotatably connected to the refrigerator main body 11. Further, since the food pocket 26 is provided, the weight becomes large, and a large load is generated on the upper hinge 23 and the lower hinge 24. In particular, the strength of the lower door hinge 37 to which the load is applied is important.

さらに開扉動作時、図１１に示すように、回転扉１７ａの回転規制部材１０２と、下ヒンジ２４の回転規制部材接触部２４ｂが、接触することにより、回転扉１７ａが開く範囲を規制している。その為、回転扉１７ａの開扉時に、回転規制部材１０２と、その底辺締結手段１０３には、強い衝撃力が生じる。 Further, during the door opening operation, as shown in FIG. 11, the rotation restricting member 102 of the revolving door 17a and the rotation restricting member contact portion 24b of the lower hinge 24 come into contact with each other to regulate the opening range of the revolving door 17a. There is. Therefore, when the revolving door 17a is opened, a strong impact force is generated on the rotation restricting member 102 and the bottom fastening means 103 thereof.

これにより、縁枠底辺部３４ｂの底辺締結手段１０３近傍が破損する可能性がある。仮に、下ヒンジ２４が破損し、断熱扉筐体２１が冷蔵庫本体１１より脱落すると、重大な事故に至る恐れがある。そこで、仮に下ヒンジ２４が破損した場合においても、断熱扉筐体２１が冷蔵庫本体１１より脱落しない構造にすることが求められる。 As a result, the vicinity of the bottom edge fastening means 103 of the edge frame bottom edge portion 34b may be damaged. If the lower hinge 24 is damaged and the heat insulating door housing 21 falls off from the refrigerator main body 11, a serious accident may occur. Therefore, even if the lower hinge 24 is damaged, it is required to have a structure in which the heat insulating door housing 21 does not fall off from the refrigerator main body 11.

従来の冷蔵庫の回転扉では、その内部に発泡ウレタンを充填することで、発泡ウレタンの接着効果で回転扉の補強効果が得られていた。 In the revolving door of a conventional refrigerator, by filling the inside with urethane foam, the effect of reinforcing the revolving door has been obtained by the adhesive effect of urethane foam.

回転扉１７ａの内部空間に真空断熱材３５のみを用いた本実施の形態における回転扉１７ａにおいては、必要な補強効果を確保するため、縁枠底辺部３４ｂと縁枠側辺部３４ｃを補強金属１０５で連結する。 In the revolving door 17a in the present embodiment in which only the vacuum heat insulating material 35 is used for the internal space of the revolving door 17a, the rim frame bottom side portion 34b and the rim frame side side portion 34c are made of reinforcing metal in order to secure the necessary reinforcing effect. Connect at 105.

例えば、図１０、図１２Ａ、図１２Ｂ、図１２Ｃで示すように、縁枠底辺部３４ｂにおいては、補強金属１０５に穴部１０５ｃを設けて、下ヒンジ２４の丸棒形状２４ａを挿入すると良い。このことにより、縁枠部３４が破損した場合においても、回転扉１７ａが脱落する可能性を抑制できる。穴部１０５ｃの形状は、貫通穴形状またはＵ字形状とする。 For example, as shown in FIGS. 10, 12A, 12B, and 12C, in the edge frame bottom base 34b, it is preferable to provide a hole 105c in the reinforcing metal 105 and insert the round bar shape 24a of the lower hinge 24. As a result, even if the edge frame portion 34 is damaged, the possibility that the revolving door 17a will fall off can be suppressed. The shape of the hole 105c is a through hole shape or a U shape.

また、金属製の回転規制部材１０２に穴部１０２ａを設けて、補強金属１０５と、縁枠底辺部３４ｂを挟み込むように底辺締結手段１０３で固定することで、より回転扉１７ａが脱落する可能性を抑制できる。 Further, by providing the hole 102a in the metal rotation restricting member 102 and fixing the reinforcing metal 105 and the bottom edge portion 34b of the edge frame with the bottom fastening means 103 so as to sandwich the reinforcing metal 105, the revolving door 17a may fall off more. Can be suppressed.

加えて、回転規制部材１０２は、回転扉１７ａの開扉時に強い衝撃力が加わる為、縁枠底辺部３４ｂの一部に凸形状１０６を設けて、補強金属１０５の縁枠嵌合部１０５ａに挿入することで、底辺締結手段１０３以外にも応力が分散する構造にすると良い。加えて、補強金属１０５の前板部３３側に折返し部１０５ｄを設け、縁枠底辺部３４ｂに設けた前板接着部１０９で挟み込み構造とすると良い。挟み込み構造によって、縁枠底辺部３４ｂとだけでなく、前板部３３にも応力が分散でき、強度が向上する。 In addition, since the rotation restricting member 102 is subjected to a strong impact force when the revolving door 17a is opened, a convex shape 106 is provided on a part of the bottom edge portion 34b of the edge frame, and the edge frame fitting portion 105a of the reinforcing metal 105 is provided. By inserting it, it is preferable to have a structure in which stress is dispersed in addition to the bottom fastening means 103. In addition, it is preferable that the folded-back portion 105d is provided on the front plate portion 33 side of the reinforcing metal 105, and the structure is sandwiched between the front plate adhesive portions 109 provided on the bottom edge portion 34b of the edge frame. Due to the sandwiching structure, stress can be dispersed not only to the bottom edge portion 34b of the edge frame but also to the front plate portion 33, and the strength is improved.

この応力の分散構造は、従来の構造において、ウレタンが縁枠底辺部３４ｂと補強金属１０５を接着させていた効果の代替えである。すなわち、応力の分散構造であれば、縁枠底辺部３４ｂが凹で、補強金属１０５が凸でもよく、１つではなく、複数存在していても良い。また、波形状や、縁枠底辺部３４ｂが補強金属１０５を抱え込む形状としても良く、第二の締結手段（図示せず）を用いても良い。さらには、接着剤等の接着手段（図示せず）によって固定しても良い。 This stress dispersion structure is an alternative to the effect of urethane adhering the bottom edge 34b of the edge frame and the reinforcing metal 105 in the conventional structure. That is, in the case of a stress dispersion structure, the bottom edge portion 34b of the edge frame may be concave and the reinforcing metal 105 may be convex, and there may be a plurality of reinforcing metals 105 instead of one. Further, a wavy shape or a shape in which the bottom edge portion 34b of the edge frame holds the reinforcing metal 105 may be used, and a second fastening means (not shown) may be used. Further, it may be fixed by an adhesive means (not shown) such as an adhesive.

縁枠左側辺部３４ｃにおいても、従来の構造のようなオーバーラップでは、発泡ウレタンが充填されない本実施の形態における断熱扉筐体２１において、十分な強度を確保することができない。 Even in the left side portion 34c of the edge frame, sufficient strength cannot be ensured in the heat insulating door housing 21 in the present embodiment in which urethane foam is not filled with the overlap as in the conventional structure.

そこで、補強金属１０５の側辺側締結部１０５ｂと、側辺補強金属６６と、接合縁枠部品６４とを側辺側締結手段１０７で締結することで、発泡ウレタンが充填されない構造においても、強度を確保することができる。側辺の補強構造も底辺と同じく、従来の構造において、ウレタンが縁枠左側辺部３４ｃや、側辺補強金属６６と補強金属１０５を接着させていた効果の代替えである。 Therefore, by fastening the side side fastening portion 105b of the reinforcing metal 105, the side side reinforcing metal 66, and the joint edge frame component 64 with the side side fastening means 107, the strength is strong even in a structure not filled with urethane foam. Can be secured. The reinforcing structure of the side side is also the same as the bottom side, which is an alternative to the effect of urethane adhering the left side side portion 34c of the edge frame or the side side reinforcing metal 66 and the reinforcing metal 105 in the conventional structure.

この代替え手段は、縁枠左側辺部３４ｃと、補強金属１０５を締結する構造や、嵌合手段であっても良く、補強金属１０５と、縁枠左側辺部３４ｃ、もしくは縁枠左側辺部３４ｃと固定された側辺補強金属６６とが、接触面１０８を有し固定される構造であれば代替えを成すことができる。 This alternative means may be a structure for fastening the left side side portion 34c of the edge frame and the reinforcing metal 105, or may be a fitting means, and the reinforcing metal 105 and the left side portion 34c of the edge frame or the left side portion 34c of the edge frame may be used. If the side reinforcing metal 66 fixed to the side has a contact surface 108 and is fixed, an alternative can be made.

また、図１３Ａ、１３Ｂに示すように、補強金属１０５と真空断熱材３５の間に、補強ブロック１３１を配置すると良い。補強ブロック１３１を配置することで、下部扉ヒンジ３７が受ける荷重を、垂直方向に真空断熱材３５へ伝えることができる。 Further, as shown in FIGS. 13A and 13B, the reinforcing block 131 may be arranged between the reinforcing metal 105 and the vacuum heat insulating material 35. By arranging the reinforcing block 131, the load received by the lower door hinge 37 can be vertically transmitted to the vacuum heat insulating material 35.

このことで、下ヒンジ軸受け１０１周辺に発生するモーメントを抑制し、回転扉１７ａ全体に荷重が分散され、強度が向上する。補強ブロック１３１は、補強金属１０５と真空断熱材３５の両方に接触していれば、単体の部品でも良いし、縁枠部３４の形状で構成しても良い。 As a result, the moment generated around the lower hinge bearing 101 is suppressed, the load is distributed over the entire revolving door 17a, and the strength is improved. The reinforcing block 131 may be a single component or may be configured in the shape of the edge frame portion 34 as long as it is in contact with both the reinforcing metal 105 and the vacuum heat insulating material 35.

縁枠部３４と一体で形成することで、部品点数を削減でき、コスト性に優れる。この接触は、組立公差を考慮し、無荷重時は僅かに隙間があり、荷重が負荷されたときに接触する程度でも良いし、接着手段（図示せず）を介した接触であっても良い。また、通常の樹脂成型品でも良いが、発泡ポリスチレンなどの発泡樹脂を用いると断熱と強度向上を両立できる。この場合、構造部品として用いる為に、風路に使う断熱用の発泡ポリスチレンより弾性率が高く、発泡倍率の低い発泡ポリスチレンを用いても良い。 By forming it integrally with the edge frame portion 34, the number of parts can be reduced and the cost is excellent. Considering the assembly tolerance, this contact may have a slight gap when no load is applied, and may be such that the contact is made when a load is applied, or may be a contact via an adhesive means (not shown). .. Further, although a normal resin molded product may be used, if a foamed resin such as expanded polystyrene is used, both heat insulation and strength improvement can be achieved. In this case, in order to use it as a structural component, expanded polystyrene having a higher elastic modulus and a lower expansion ratio than expanded polystyrene for heat insulation used for an air passage may be used.

次に断熱性能を考えると、上部扉ヒンジ３６、下部扉ヒンジ３７を構成する空間は、真空断熱材３５を配置することができない。しかしながら、真空断熱材３５が存在しない空間が増加すると、断熱性能が低下し、省エネ性の低下や、結露といった問題が生じる。従来例では、真空断熱材３５は板形状であり、その角部は面取りしかできず、上部扉ヒンジ３６、下部扉ヒンジ３７を真空断熱材が大きく逃げる必要があった。 Next, considering the heat insulating performance, the vacuum heat insulating material 35 cannot be arranged in the space constituting the upper door hinge 36 and the lower door hinge 37. However, if the space in which the vacuum heat insulating material 35 does not exist increases, the heat insulating performance deteriorates, which causes problems such as deterioration of energy saving and dew condensation. In the conventional example, the vacuum heat insulating material 35 has a plate shape, and its corners can only be chamfered, so that the vacuum heat insulating material needs to largely escape from the upper door hinge 36 and the lower door hinge 37.

そこで、本実施の形態では、ガスバリア性能を有し、自由に成形可能な多層シートから形成された外殻部材７２ａを用いることで、上部扉ヒンジ３６、下部扉ヒンジ３７の構造に合わせて、段付き形や、円弧形状を可能にする。これにより、上部扉ヒンジ３６、下部扉ヒンジ３７を逃げる真空断熱材３５が最小限になり、非断熱空間が小さいことから、断熱性能が向上する。 Therefore, in the present embodiment, by using the outer shell member 72a which has gas barrier performance and is formed of a freely moldable multilayer sheet, the step is matched to the structure of the upper door hinge 36 and the lower door hinge 37. Enables attached shapes and arc shapes. As a result, the vacuum heat insulating material 35 that escapes the upper door hinge 36 and the lower door hinge 37 is minimized, and the non-insulated space is small, so that the heat insulating performance is improved.

以上のように本実施の形態の冷蔵庫は、冷蔵庫本体１１と、回転扉１７ａと、下ヒンジ２４（ヒンジ部材）を有する。冷蔵庫本体１１は前面開口部（図示せず）を有し、回転扉１７ａは、前面開口部を開閉する。下ヒンジ２４は、回転扉１７ａを回転自在に支持する。回転扉１７ａは、前面開口部から前側に位置する前板部３３と、前面開口部に面する内板部３２と、前板部３３と内板部３２の外周を覆う縁枠部３４と、前板部３３と内板部３２と縁枠部３４との間に設けた真空断熱材３５と、下ヒンジ２４（ヒンジ部材）を受ける下ヒンジ軸受け１０１（ヒンジ受け）と、下ヒンジ軸受け１０１を補強する補強金属１０５を備えている。 [1-3. Effect, etc.]
As described above, the refrigerator of the present embodiment has a refrigerator main body 11, a revolving door 17a, and a lower hinge 24 (hinge member). The refrigerator body 11 has a front opening (not shown), and the revolving door 17a opens and closes the front opening. The lower hinge 24 rotatably supports the revolving door 17a. The rotary door 17a includes a front plate portion 33 located on the front side from the front opening, an inner plate portion 32 facing the front opening, and an edge frame portion 34 covering the outer periphery of the front plate portion 33 and the inner plate portion 32. The vacuum heat insulating material 35 provided between the front plate portion 33, the inner plate portion 32, and the edge frame portion 34, the lower hinge bearing 101 (hinge bearing) that receives the lower hinge 24 (hinge member), and the lower hinge bearing 101. The reinforcing metal 105 for reinforcing is provided.

補強金属１０５で、縁枠部３４の底辺を構成する縁枠底辺部３４ｂと縁枠部３４の下ヒンジ軸受け１０１側の側辺を構成する縁枠左側辺部３４ｃ（縁枠側辺部）とを連結する。 With the reinforcing metal 105, the edge frame bottom side portion 34b forming the bottom side of the edge frame portion 34 and the edge frame left side side portion 34c (edge frame side side portion) forming the side side of the lower hinge bearing 101 side of the edge frame portion 34. To concatenate.

上記構成により、縁枠部３４の連結強度、および冷蔵庫本体１１に設けた下ヒンジ２４と連結される下ヒンジ軸受け１０１の強度が向上し、回転扉１７ａのヒンジ強度が向上する。 With the above configuration, the connecting strength of the edge frame portion 34 and the strength of the lower hinge bearing 101 connected to the lower hinge 24 provided on the refrigerator main body 11 are improved, and the hinge strength of the revolving door 17a is improved.

また、補強金属１０５に、下ヒンジ２４の丸棒形状２４ａが挿入される穴部１０５ｃを設け、その穴部１０５ｃの形状を、貫通穴形状またはＵ字形状とする。この構成により、回転扉１７ａの縁枠部３４が破損した場合においても、補強金属１０５により、下ヒンジ２４の丸棒形状２４ａが回転扉１７ａの外側への飛び出しことを防ぐ。このことにより、回転扉１７ａが冷蔵庫本体１１から落下することがなくなり、回転扉１７ａの落下等の危険性を抑制することができる。 Further, the reinforcing metal 105 is provided with a hole 105c into which the round bar shape 24a of the lower hinge 24 is inserted, and the shape of the hole 105c is a through hole shape or a U shape. With this configuration, even if the edge frame portion 34 of the revolving door 17a is damaged, the reinforcing metal 105 prevents the round bar shape 24a of the lower hinge 24 from protruding to the outside of the revolving door 17a. As a result, the revolving door 17a does not fall from the refrigerator main body 11, and the risk of the revolving door 17a falling can be suppressed.

さらに、補強金属１０５と縁枠底辺部３４ｂは、固定手段（図示せず））により、下ヒンジ軸受け１０１、回転扉１７ａの回転を規制する回転規制部材１０２、ラッチ１０４の少なくとも一つと固定されていることにより、下ヒンジ軸受け１０１を複数の物体で囲み固定することができ、強度と信頼性が向上する。また、複数の物体を固定する組立工数を省くことができ、生産性に優れる。 Further, the reinforcing metal 105 and the bottom edge portion 34b of the edge frame are fixed to at least one of the lower hinge bearing 101, the rotation restricting member 102 that regulates the rotation of the rotary door 17a, and the latch 104 by a fixing means (not shown). As a result, the lower hinge bearing 101 can be surrounded and fixed by a plurality of objects, and the strength and reliability are improved. In addition, the assembly man-hours for fixing a plurality of objects can be omitted, and the productivity is excellent.

また、補強金属１０５と縁枠底辺部３４ｂの連結部は、応力分散構造を有することにより、回転規制部材１０２が回転規制時に受ける衝撃力を、補強金属１０５と縁枠底辺部３４ｂの締結部のみから、縁枠底辺部３４ｂの周辺に応力を分散させることができ、強度が向上する。 Further, since the connecting portion between the reinforcing metal 105 and the edge frame bottom portion 34b has a stress dispersion structure, the impact force received by the rotation regulating member 102 at the time of rotation regulation is applied only to the fastening portion between the reinforcing metal 105 and the edge frame bottom portion 34b. Therefore, the stress can be dispersed around the bottom edge portion 34b of the edge frame, and the strength is improved.

さらに、上記応力分散構造を、補強金属１０５と縁枠底辺部３４ｂとを嵌合させて形成することで、補強金属１０５と縁枠底辺部３４ｂに第二の締結手段や、接着部材を設ける必要がなくなり、生産性が向上する。 Further, by forming the stress dispersion structure by fitting the reinforcing metal 105 and the bottom edge portion 34b of the edge frame, it is necessary to provide a second fastening means and an adhesive member on the reinforcing metal 105 and the bottom edge portion 34b of the edge frame. Eliminates and improves productivity.

また、補強金属１０５と真空断熱材３５との間に、補強ブロック１３１を設けたことにより、下ヒンジ軸受け１０１や、縁枠底辺部３４ｂが受ける荷重を、真空断熱材３５に垂直方向に伝えることができ、モーメント荷重が抑制でき、下ヒンジ２４の強度が向上する。 Further, by providing the reinforcing block 131 between the reinforcing metal 105 and the vacuum heat insulating material 35, the load received by the lower hinge bearing 101 and the bottom edge portion 34b of the edge frame is transmitted to the vacuum heat insulating material 35 in the vertical direction. The moment load can be suppressed, and the strength of the lower hinge 24 is improved.

また、補強金属１０５と縁枠左側辺部３４ｃ（縁枠側辺部）は、接触面１０８を介して固定されたことにより、補強金属１０５が受ける、ねじり荷重を縁枠左側辺部３４ｃに伝えることができ、応力が分散し、下ヒンジ２４の強度が向上する。 Further, since the reinforcing metal 105 and the left side side portion 34c of the edge frame (edge frame side side portion) are fixed via the contact surface 108, the torsional load received by the reinforcing metal 105 is transmitted to the left side portion 34c of the edge frame. The stress can be dispersed and the strength of the lower hinge 24 is improved.

さらに、補強金属１０５と、縁枠左側辺部３４ｃを構成する樹脂部品と、縁枠左側辺部３４ｃ補強する側辺補強金属６６（側辺補強部材）とを、側辺側締結手段１０７によって共締めしたことにより、補強金属１０５と縁枠左側辺部３４ｃに第二の締結手段や、接着部材を設ける必要がなくなり、生産性に優れる。 Further, the reinforcing metal 105, the resin parts constituting the left side portion 34c of the edge frame, and the side side reinforcing metal 66 (side side reinforcing member) for reinforcing the left side portion 34c of the edge frame are combined by the side side fastening means 107. By tightening, it is not necessary to provide a second fastening means or an adhesive member on the reinforcing metal 105 and the left side side portion 34c of the edge frame, and the productivity is excellent.

また、真空断熱材３５を、下ヒンジ２４（ヒンジ部材）を避けるように、段付き形状または、円弧形状に形成したことにより、回転扉１７ａ内の真空断熱材３５を下ヒンジ２４の近傍まで配置することができ、下ヒンジ２４周辺の防露性能、回転扉１７ａの断熱性能が向上し、省エネ性能が向上する。 Further, by forming the vacuum heat insulating material 35 in a stepped shape or an arc shape so as to avoid the lower hinge 24 (hinge member), the vacuum heat insulating material 35 in the rotary door 17a is arranged close to the lower hinge 24. The dew-proof performance around the lower hinge 24 and the heat insulating performance of the rotary door 17a are improved, and the energy-saving performance is improved.

また、真空断熱材３５をガスバリア性能を有し凹形の外殻部材７２ａに収容し、真空断熱材３５を同じくガスバリア性能を有すると共に外殻部材７２ａと異なる第二の外殻部材７２ｂで封止したことにより、真空断熱材３５の形状自由度が向上し、省エネ性能の高い回転扉１７ａを提供できる。 Further, the vacuum heat insulating material 35 is housed in the concave outer shell member 72a having gas barrier performance, and the vacuum heat insulating material 35 is sealed with a second outer shell member 72b which also has gas barrier performance and is different from the outer shell member 72a. As a result, the degree of freedom in the shape of the vacuum heat insulating material 35 is improved, and the rotary door 17a having high energy-saving performance can be provided.
