Description

本発明は、扉の表面に外板を備えた冷蔵庫に関する。 The present invention relates to a refrigerator having an outer panel on the surface of the door.

近年の冷蔵庫の扉としては、光沢性を向上させるために、扉の表面にガラス製の外板を設けて意匠性を向上したものが普及している。また、外板の上下左右の４辺のうち、一部の辺を断面コ字状の枠部材で支持し、残りの辺を断面Ｌ字状の枠部材で支持した冷蔵庫がある。例えば、下記特許文献１には、左右に隣接する２枚の回動式の冷蔵室扉について、外板の回転軸側を断面コ字状の枠部材で支持し、外板の反回転軸側を断面Ｌ字状の枠部材で支持した冷蔵庫が開示されている。 2. Description of the Related Art In recent years, as a refrigerator door, in order to improve glossiness, a door having an outer plate made of glass provided on the surface of the door to improve the design has become popular. In addition, there is a refrigerator in which some of the four sides of the outer plate, upper, lower, left, and right, are supported by a frame member having a U-shaped cross section, and the remaining sides are supported by a frame member having an L-shaped cross section. For example, Patent Literature 1 below describes two rotating refrigerating compartment doors that are laterally adjacent to each other. is supported by a frame member having an L-shaped cross section.

しかしながら、上記特許文献１に記載の発明は、１つの外板のうち、一部をコ字状の枠部材で支持し、残りをＬ字状の枠部材で支持するものに過ぎません。また、使用者の視線の近くにある冷蔵室扉について、回転軸側における外板の前面が枠部材で覆われているため、意匠性が低下する懸念がある。 However, the invention described in Patent Literature 1 merely supports a part of one outer plate with a U-shaped frame member and the rest with an L-shaped frame member. In addition, since the front surface of the outer plate on the rotating shaft side of the refrigerating compartment door located near the user's line of sight is covered with the frame member, there is a concern that the design may deteriorate.

本発明の目的は、各扉の場所や形状を考慮した、各扉に適した外板の支持方法を採用することにより、意匠性を向上させた冷蔵庫を提供することにある。 SUMMARY OF THE INVENTION An object of the present invention is to provide a refrigerator with improved design by adopting a method of supporting an outer panel suitable for each door, taking into account the location and shape of each door.

図２は、回動式の断熱扉を示す分解斜視図である。 FIG. 2 is an exploded perspective view showing a pivotable heat insulating door.

図２に示すように、断熱扉２ａは、断熱扉２ａの表面に設けられたガラス製の外板１０と、外板１０の周縁に設けられた扉枠２０と、外板１０の裏面に配置された真空断熱材３０と、外板１０と扉枠２０とで形成された空間４０に真空断熱材３０を介在させて充填された発泡断熱材５０（図３参照）と、扉枠２０の裏面（背面）に設けられた内板６０と、を備えて構成されている。 As shown in FIG. 2, the heat insulating door 2a is arranged on the back surface of the outer plate 10 made of glass provided on the surface of the heat insulating door 2a, the door frame 20 provided on the periphery of the outer plate 10, and the outer plate 10. a foamed heat insulating material 50 (see FIG. 3) filled with the vacuum heat insulating material 30 interposed in the space 40 formed by the outer plate 10 and the door frame 20, and the back surface of the door frame 20. and an inner plate 60 provided on the (rear surface).

外板１０は、断熱扉２ａの表面（前面）側の外壁（外郭、意匠面）を形成する透光性の矩形の平板部材から成る。外板１０の外周部は、縦長の四角枠状の扉枠２０の内側前端部に装着されて、扉枠２０によって覆われている。この扉枠２０は、例えば、ＡＢＳ（アクリロニトリルブタジエンスチレン共重合体）樹脂で形成されている。 The outer plate 10 is made of a translucent rectangular flat plate member that forms an outer wall (outer shell, design surface) on the surface (front) side of the heat insulating door 2a. An outer peripheral portion of the outer plate 10 is attached to an inner front end portion of a vertically long rectangular door frame 20 and covered with the door frame 20 . The door frame 20 is made of, for example, ABS (acrylonitrile-butadiene-styrene copolymer) resin.

扉枠２０は、外板１０の右側縁部に沿って形成される外側枠部材２１と、外板１０の左側縁部に沿って形成される内側枠部材２２と、外板１０の上側縁部に沿って形成される上側枠部材２３と、外板１０の下側縁部に沿って形成される下側枠部材２４と、が組み合わせて構成されている。 The door frame 20 includes an outer frame member 21 formed along the right edge of the outer plate 10, an inner frame member 22 formed along the left edge of the outer plate 10, and an upper edge of the outer plate 10. and a lower frame member 24 formed along the lower edge of the outer plate 10 are combined.

枠部材２１，２２，２３，２４には、外板１０の外周縁部と反応型ホットメルト接着剤７０（以下、接着剤７０と略記する）によって接着されるフランジ部（つば部）２１ａ，２２ａ，２３ａ，２４ａが形成されている。なお、外板１０は、強化ガラス製の平板材が好ましいが、プラスチック等の透光性の平板材や、セラミック等の陶器性の平板材であってもよい。 Frame members 21, 22, 23, and 24 have flange portions (collar portions) 21a and 22a that are bonded to the outer periphery of outer plate 10 with reactive hot-melt adhesive 70 (hereinafter abbreviated as adhesive 70). , 23a and 24a are formed. The outer plate 10 is preferably a flat plate made of tempered glass, but may be a translucent flat plate such as plastic or a porcelain flat plate such as ceramic.

なお、本実施形態では、外板１０の外周４辺をフランジ部（つば部）２１ａ，２２ａ，２３ａ，２４ａと接着剤７０で接着した場合を例に説明するが、外周４辺に限定されるものではなく、少なくとも１辺以上接着剤７０で接着され、その他の辺はフランジ部（つば部）２１ａ，２２ａ，２３ａ，２４ａと両面接着テープ（図示せず）で接着してもよい。 In this embodiment, the case where the four outer sides of the outer plate 10 are adhered to the flange portions (collar portions) 21a, 22a, 23a, and 24a with the adhesive 70 will be described as an example, but the outer plate 10 is limited to the four outer sides. Instead, at least one side or more may be adhered with the adhesive 70, and the other sides may be adhered to the flange portions (collar portions) 21a, 22a, 23a, and 24a with a double-sided adhesive tape (not shown).

また、本実施形態では、外板１０の外周４辺をフランジ部２１ａ，２２ａ，２３ａ，２４ａと接着剤７０で接着した場合を例に説明するが、外周４辺を両面接着テープ（図示せず）で接着してもよい。 Further, in the present embodiment, a case where the four outer sides of the outer plate 10 are adhered to the flange portions 21a, 22a, 23a, and 24a with the adhesive 70 will be described as an example. ).

図３は、図１のＩＩＩ－ＩＩＩ線断面図である。尚、本実施の形態では、断熱扉２ａの説明をしているが、左右方向に並んで設けられた断熱扉２ｂは左右対称の構成のため、断熱扉２ｂの説明は省略する。 FIG. 3 is a cross-sectional view taken along line III-III of FIG. In this embodiment, the heat insulating door 2a is explained, but the heat insulating door 2b arranged in the horizontal direction has a symmetrical structure, so the explanation of the heat insulating door 2b is omitted.

図３に示すように、外側枠部材２１は、表裏方向（冷蔵庫１の前後方向）に沿って延びる板状の本体部２１ｂを有している。本体部２１ｂには、外板１０側に沿い、かつ、本体部２１ｂに直交して延びるフランジ部２１ａが形成されている。このフランジ部２１ａは、外側枠部材２１の表側の略端部に位置している。また、本体部２１ｂには、フランジ部２１ａと平行に延びる補強リブ２１ｃが形成されている。この補強リブ２１ｃは、外側枠部材２１の補強としての機能と、外側枠部材２１と発泡断熱材５０との接着性を高める機能とを有している。 As shown in FIG. 3, the outer frame member 21 has a plate-like body portion 21b extending along the front and back direction (the front-rear direction of the refrigerator 1). The body portion 21b is formed with a flange portion 21a that extends along the outer plate 10 side and perpendicularly to the body portion 21b. The flange portion 21 a is positioned substantially at the front end portion of the outer frame member 21 . A reinforcing rib 21c extending parallel to the flange portion 21a is formed on the body portion 21b. The reinforcing ribs 21 c have a function of reinforcing the outer frame member 21 and a function of enhancing adhesion between the outer frame member 21 and the foamed heat insulating material 50 .

真空断熱材３０は、その材質は特に限定されないが、一例を挙げると、多孔質構造のグラスウール等の芯材をラミネートフィルムで真空パックして内部を減圧して封止した断熱材から成り、気体熱伝導率が略ゼロであるため、優れた断熱性能を有している。また、真空断熱材３０は、平板状に形成され、外板１０の裏面側に接着されている。 The material of the vacuum heat insulating material 30 is not particularly limited, but as an example, it is made of a heat insulating material in which a core material such as glass wool having a porous structure is vacuum-packed with a laminate film and the inside is depressurized and sealed. Since the thermal conductivity is almost zero, it has excellent heat insulation performance. Also, the vacuum heat insulating material 30 is formed in a flat plate shape and adhered to the back side of the outer plate 10 .

断熱扉２ａは、外板１０と内板６０とが前後方向（表裏方向）に離間して配置され、空間４０の表面側に真空断熱材３０が配置され、真空断熱材３０を除く空間に発泡断熱材５０が配置されるように構成されている。真空断熱材３０は、外板１０よりも左右方向（幅方向）の長さが短く形成され、真空断熱材３０の左端と内側枠部材２２との間にも発泡断熱材５０が充填されている。 The heat insulating door 2a has an outer plate 10 and an inner plate 60 spaced apart in the front-rear direction (front and back direction), a vacuum heat insulating material 30 disposed on the surface side of the space 40, and foaming in the space excluding the vacuum heat insulating material 30. A heat insulating material 50 is arranged. The vacuum heat insulating material 30 is shorter in the left-right direction (width direction) than the outer plate 10, and the foam heat insulating material 50 is also filled between the left end of the vacuum heat insulating material 30 and the inner frame member 22. .

発泡断熱材５０は、断熱材としての機能と、接着剤としての機能と、を備えている。また、発泡断熱材５０は、中央部に真空断熱材３０を載置した外板１０と、外板１０の外周に取り付けられた扉枠２０とで形成された空間４０に、真空断熱材３０を介在させて充填されることによって、空間４０の内壁面に接着される。このため、発泡断熱材５０は、真空断熱材３０を覆った状態で外板１０の裏面に接着されている。 The foam heat insulating material 50 has a function as a heat insulating material and a function as an adhesive. In addition, the foam heat insulating material 50 is formed by placing the vacuum heat insulating material 30 in the space 40 formed by the outer plate 10 having the vacuum heat insulating material 30 placed in the center and the door frame 20 attached to the outer periphery of the outer plate 10. It adheres to the inner wall surface of the space 40 by interposing and filling. For this reason, the foam heat insulating material 50 is adhered to the rear surface of the outer plate 10 while covering the vacuum heat insulating material 30 .

尚、本実施の形態では、真空断熱材３０は外板１０の裏面側に接着しているが、この構成に限らず、真空断熱材３０は内板６０側に接着されていてもよく、また、外板１０と内板６０の何れにも接着されず、真空断熱材３０の表裏面に発泡断熱材５０が介在した状態であってもよい。 In the present embodiment, the vacuum heat insulating material 30 is adhered to the back side of the outer plate 10, but the configuration is not limited to this, and the vacuum heat insulating material 30 may be adhered to the inner plate 60 side. , the foamed heat insulating material 50 may be interposed between the front and back surfaces of the vacuum heat insulating material 30 without being adhered to either the outer plate 10 or the inner plate 60 .

また、発泡断熱材５０は、硬質ウレタンフォームで形成されている。この硬質ウレタンフォームは、断熱扉２ａの内側の空間４０内に注入したウレタンフォーム原液（発泡断熱材の原料液）が発泡した後、硬化して形成されたものである。ちなみに、ウレタンフォーム原液としては、例えば、ポリエーテルポリオールに、シクロペンタン、水などの発泡剤、さらには触媒、整泡剤などの助剤をプレミックスした液と、イソシアネート液とを混合した液体が挙げられる。 Moreover, the foamed heat insulating material 50 is made of rigid urethane foam. This rigid urethane foam is formed by curing after foaming a urethane foam undiluted solution (raw heat insulating material liquid) injected into the space 40 inside the heat insulating door 2a. By the way, as a urethane foam undiluted solution, for example, a liquid obtained by premixing a polyether polyol with a foaming agent such as cyclopentane and water, as well as an auxiliary agent such as a catalyst and a foam stabilizer, and an isocyanate solution is mixed. mentioned.

内板６０は、断熱扉２ａの貯蔵室側に設けられた樹脂製（ＡＢＳなど）の板部材である。また、内板６０は、扉枠２０の裏面側の周縁部に固定されている。また、内板６０の裏面側の外周部には、断熱扉２ａを冷蔵庫本体と密着させて貯蔵室の気密性を確保するためのシール部材（図示省略）が設けられている。 The inner plate 60 is a plate member made of resin (such as ABS) provided on the storage room side of the heat insulating door 2a. In addition, the inner plate 60 is fixed to the peripheral portion on the back side of the door frame 20 . A seal member (not shown) is provided on the outer periphery of the back side of the inner plate 60 to keep the heat-insulating door 2a in close contact with the refrigerator body to ensure the airtightness of the storage compartment.

また、図３では太線で簡略化して図示しているが、外板１０の裏面には、塗料層８０が設けられ、塗料層８０の裏面には、飛散防止フィルム９０が設けられている。塗料層８０と飛散防止フィルム９０の詳細については後記する（図７参照）。 3, a coating layer 80 is provided on the back surface of the outer panel 10, and a scattering prevention film 90 is provided on the back surface of the coating layer 80, although this is simplified by thick lines in FIG. Details of the paint layer 80 and the anti-scattering film 90 will be described later (see FIG. 7).

図４は、図３の要部Ｐ１を概略的に示す断面図である。なお、図４は、内側枠部材２２のフランジ部２２ａとその周辺を示す拡大断面図である。 FIG. 4 is a cross-sectional view schematically showing the main part P1 of FIG. 3. As shown in FIG. 4 is an enlarged sectional view showing the flange portion 22a of the inner frame member 22 and its periphery.

図４に示すように、フランジ部２２ａは、外板１０に平行に沿って延びる断面視において板状の部材である。また、フランジ部２２ａは、図４の紙面に直交する方向に延びて形成されている（図２参照）。また、フランジ部２２ａには、外板１０側の面に、外板１０に向けて突出するリブ２２ｄが形成されている。このリブ２２ｄは、フランジ部２２ａの基端側に位置している。 As shown in FIG. 4 , the flange portion 22a is a plate-like member extending parallel to the outer plate 10 in a cross-sectional view. Further, the flange portion 22a is formed extending in a direction orthogonal to the paper surface of FIG. 4 (see FIG. 2). A rib 22d projecting toward the outer plate 10 is formed on the surface of the flange portion 22a on the outer plate 10 side. The rib 22d is located on the base end side of the flange portion 22a.

外板１０は、平板状の部材から成り、その端部の表面側の角部と裏面側の角部とに、面取部１０ａ，１０ａが形成されている。なお、面取部１０ａは、角部が直線状にカットされたものであるが、このような形状に限定されるものではなく、破線で示すように、端面の全体が湾曲状（円弧状）に形成されていてもよい。また、面取部１０ａは外板１０の表面側のみに形成してもよい。 The outer plate 10 is made of a flat member, and chamfered portions 10a, 10a are formed at the corners on the front side and the corners on the back side of the ends thereof. Although the chamfered portion 10a has a straight corner cut, the shape is not limited to such a shape. may be formed in Further, the chamfered portion 10a may be formed only on the surface side of the outer plate 10. As shown in FIG.

内側枠部材２２は、本体部２２ｂから表面側に延びて、外板１０の端面と近接する近接部２２ｅが一体に形成されている。このとき、外板１０の端面と近接部２２ｅとの間の隙間Ｓ１の寸法は小さいことが好ましい。隙間Ｓ１の寸法は、外板１０及び枠部材２０の組み立て時の寸法で生じるばらつき（嵌め合い公差）を考慮して０．５ｍｍ以下とすることが好ましく、外観意匠性を考慮すると０に近しい方がより好ましい。 The inner frame member 22 is integrally formed with a proximal portion 22e that extends from the main body portion 22b to the surface side and is adjacent to the end surface of the outer plate 10 . At this time, it is preferable that the dimension of the gap S1 between the end surface of the outer plate 10 and the adjacent portion 22e is small. The dimension of the gap S1 is preferably 0.5 mm or less in consideration of the variation (fitting tolerance) that occurs in the dimensions of the outer plate 10 and the frame member 20 when assembled. is more preferred.

近接部２２ｅの左右方向の板厚は、本体部２２ｂの板厚よりも薄く形成されている。また、本体部２２ｂの左側（隣り合う断熱扉２ｂと近接する側）の表面２２ｂ１と、近接部２２ｅの左側の表面２２ｅ１とは、面一となるように構成されている。これらにより、使用者が冷蔵庫を正面視した際に近接部２２ｅは目立ち難くなり、左右に隣接して設けられた断熱扉２ａ及び２ｂの表面は、一枚の大きなガラス面のように見せることができ、外観意匠性を向上できる。 The plate thickness in the left-right direction of the proximity portion 22e is formed thinner than the plate thickness of the main body portion 22b. The left surface 22b1 of the body portion 22b (the side adjacent to the adjacent heat insulating door 2b) and the left surface 22e1 of the adjacent portion 22e are configured to be flush with each other. As a result, when the user views the refrigerator from the front, the adjacent portion 22e becomes less noticeable, and the surfaces of the heat insulating doors 2a and 2b provided adjacent to each other on the left and right can be seen as one large glass surface. It is possible to improve the appearance design.

フランジ部２２ａに形成されたリブ２２ｄは、面取部１０ａ，１０ａの位置（一点鎖線で示すラインＬ１）よりも内側（左右方向の中心側）に位置している。これにより、外板１０とリブ２２ｄとの隙間が大きくなるのを防止できる。 The rib 22d formed on the flange portion 22a is located inside (the center side in the left-right direction) of the chamfered portions 10a, 10a (the line L1 indicated by the dashed-dotted line). Thereby, it is possible to prevent the gap between the outer plate 10 and the rib 22d from becoming large.

また、外板１０の表面部は近接部２２ｅの前端よりも前側に位置する。このとき、面取り部１０ａの少なくとも一部が露出することで、外板１０の面取り部１０ａと近接部２２ｅの前端部とが連続した傾斜面のように表現でき、外観意匠性を向上することができる
また、リブ２２ｄよりも内側のフランジ部２２ａには、接着剤７０が塗布される。そして、外板１０によって接着剤７０が押圧されることで、外板１０が内側枠部材２２に接着・固定される。なお、図４においてドットで示す接着剤７０が、固定後の状態を示し、一点鎖線で示す楕円形状のものが、固定前（外板１０を押しつける前）の状態を示している。固定前の接着剤７０は、リブ２２ｄの高さよりも高く形成されている。 Further, the surface portion of the outer plate 10 is positioned forward of the front end of the proximal portion 22e. At this time, by exposing at least a portion of the chamfered portion 10a, the chamfered portion 10a of the outer plate 10 and the front end portion of the proximal portion 22e can be represented as a continuous inclined surface, thereby improving the appearance design. Also, an adhesive 70 is applied to the flange portion 22a inside the rib 22d. Then, the outer plate 10 is adhered and fixed to the inner frame member 22 by pressing the adhesive 70 with the outer plate 10 . In FIG. 4, the adhesive agent 70 indicated by dots indicates the state after fixing, and the elliptical one indicated by the one-dot chain line indicates the state before fixing (before the outer plate 10 is pressed). The adhesive 70 before fixing is formed higher than the height of the rib 22d.

ここで、ホットメルト接着剤の厚みについて説明する。本実施形態では、接着剤７０の厚みを、デザイン上、加工が困難な部位を除いて０．４ｍｍより大きく０．６ｍｍ以下としている。 Here, the thickness of the hot-melt adhesive will be explained. In this embodiment, the thickness of the adhesive 70 is greater than 0.4 mm and less than or equal to 0.6 mm, except for portions where processing is difficult due to the design.

接着剤７０は、プレポリマーとイソシアネートとが混合されたものであり、反応性が高いものである。使用する場合には、接着剤７０を熱で溶かして（軟化させて）所定位置に流し込む（塗布する）ことで、空気中の水分を利用してイソシアネートの反応が進み、ガスが発生するとともにウレタン結合が生成される。このとき、図４に示すように、外板１０とリブ２２ｄとの間に隙間が形成されるように構成することで、発生したガスを外部に逃がすことができる。 The adhesive 70 is a mixture of prepolymer and isocyanate and is highly reactive. When used, the adhesive 70 is melted (softened) by heat and then poured (applied) into a predetermined position, whereby the reaction of isocyanate proceeds using the moisture in the air, generating gas and urethane. A bond is generated. At this time, as shown in FIG. 4, by forming a gap between the outer plate 10 and the rib 22d, the generated gas can escape to the outside.

図５は、図３の要部Ｐ２を概略的に示す断面図である。 FIG. 5 is a cross-sectional view schematically showing the main part P2 of FIG.

図５に示すように、外側枠部材２１は、表面側において外板１０の裏面に沿ってフランジ部２１ａが形成されている。 As shown in FIG. 5, the outer frame member 21 has a flange portion 21a formed along the back surface of the outer plate 10 on the surface side.

フランジ部２１ａに形成されたリブ２１ｄは、面取部１０ａの位置よりも内側に位置している。これにより、外板１０とリブ２１ｄとの隙間が大きくなるのを防止できる。また、図示はないが図４と同様に、フランジ部２１ａのリブ２１ｄよりも内側に接着剤７０が塗布される。 A rib 21d formed on the flange portion 21a is located inside the position of the chamfered portion 10a. Thereby, it is possible to prevent the gap between the outer plate 10 and the rib 21d from becoming large. Although not shown, the adhesive 70 is applied to the inside of the ribs 21d of the flange portion 21a in the same manner as in FIG.

外側枠部材２１は、本体部２１ｂから手前側に延びて外板１０の端面を覆う前延部２１ｅが形成される。前延部２１ｅは、断面略Ｌ字形状もしくは略円弧状に形成されており、近接面２１ｅ２と外板１０の端面とが向かい合うように位置する。 The outer frame member 21 is formed with a front extending portion 21e that extends forward from the body portion 21b and covers the end face of the outer plate 10. As shown in FIG. The forward extending portion 21e is formed to have a substantially L-shaped or substantially arcuate cross section, and is positioned so that the proximal surface 21e2 and the end surface of the outer plate 10 face each other.

近接面２１ｅ２は、フランジ部２１ａの本体部２１ｂ側の端部よりも外板１０側に位置し、前延部２１ｅは厚肉に形成される。また、前延部２１ｅの意匠面２１ｅ１は、外板１０の表面よりも前側に位置する。これらにより、外板１０の端部を外部の衝撃から守ることができる。 The proximal surface 21e2 is positioned closer to the outer plate 10 than the end of the flange portion 21a on the main body portion 21b side, and the forward extension portion 21e is formed thick. Further, the design surface 21 e 1 of the forward extending portion 21 e is located forward of the surface of the outer panel 10 . As a result, the edge of the outer plate 10 can be protected from external impact.

本実施の形態において、前延部２１ｅの板厚ｔ２の寸法は、本体部２１ｂの板厚ｔ１と同等に形成されている。例えば、本体部２１ｂの板厚ｔ１を２～３ｍｍ、前延部２１ｅの板厚ｔ２を２～３ｍｍとしている。 In the present embodiment, the thickness t2 of the forward extending portion 21e is equal to the thickness t1 of the main body portion 21b. For example, the plate thickness t1 of the body portion 21b is set to 2 to 3 mm, and the plate thickness t2 of the forward extension portion 21e is set to 2 to 3 mm.

前延部２１ｅは、近接面２１ｅ２より反外板１０側に形成された凹状の溝部２１ｆ（肉盗み部）を有する。この溝部２１ｆは、前延部２１ｅの長手方向の略全幅に連続して設けられる。 The forward extending portion 21e has a recessed groove portion 21f (recessed portion) formed on the side opposite to the outer plate 10 from the proximal surface 21e2. The groove portion 21f is provided continuously over substantially the entire width in the longitudinal direction of the forward extension portion 21e.

ここで、溝部２１ｆを形成しない場合の前延部２１ｅの端部を仮想線Ｌ２（一点鎖線）で示し、その仮想線Ｌ２と直交する方向の前延部２１ｅの板厚ｔ３は５～７ｍｍとする。このように、外側枠部材２１を樹脂成形する際、板厚ｔ１に対して前延部２１ｅ側の板厚ｔ３が大きいと、その肉厚差が生じる箇所の付近にヒケ（シンクマーク。肉厚差が原因で肉厚部の表面に生じる凹み。）が生じる虞がある。 Here, the edge of the forward extension 21e in the case where the groove 21f is not formed is indicated by an imaginary line L2 (one-dot chain line), and the plate thickness t3 of the forward extension 21e in the direction orthogonal to the imaginary line L2 is 5 to 7 mm. do. As described above, when the outer frame member 21 is resin-molded, if the plate thickness t3 on the side of the forward extending portion 21e is larger than the plate thickness t1, a sink mark (sink mark) occurs near the portion where the thickness difference occurs. There is a risk that a dent may occur on the surface of the thick portion due to the difference.

以上、本実施の形態では、前延部２１ｅの左右方向の板厚を全体的に大きくするのではなく、部分的に溝部２１ｆ（肉盗み部）を設け、前延部２１ｅの断面を略Ｌ字形状とした。溝部２１ｆを設けたことで、外枠部材２１の板厚ｔ１から板厚ｔ２にかけての肉厚差を小さくし、ヒケの発生を抑制し、外観の品質や意匠性を向上した。 As described above, in the present embodiment, instead of increasing the plate thickness of the front extension portion 21e in the left-right direction as a whole, the groove portion 21f (thickness portion) is partially provided so that the cross section of the front extension portion 21e is substantially L. character shape. By providing the groove portion 21f, the thickness difference from the plate thickness t1 to the plate thickness t2 of the outer frame member 21 is reduced, the occurrence of sink marks is suppressed, and the appearance quality and design are improved.

また、前延部２１ｅを略Ｌ字形状としたことで、意匠面２１ｅ１を広く（例えば５～６ｍｍ）形成することができる。冷蔵庫１の意匠性に大きく影響するのは外板１０の表面であり、その外板１０と隣設する前延部２１ｅの意匠面２１ｅ１を広く（例えば、本体部２１ｂの板厚以上）形成することで、断熱扉の意匠性に自由度を持たせることができ、冷蔵庫１の外観意匠性を向上することができる。 Further, by making the forward extending portion 21e substantially L-shaped, the designed surface 21e1 can be formed wide (for example, 5 to 6 mm). The design of the refrigerator 1 is greatly affected by the surface of the outer plate 10, and the design surface 21e1 of the forward extending portion 21e adjacent to the outer plate 10 is formed wide (for example, greater than or equal to the plate thickness of the main body portion 21b). Thus, the design of the heat insulating door can be given a degree of freedom, and the exterior design of the refrigerator 1 can be improved.

近接面２１ｅ２と外板１０の端面との間には隙間Ｓ２が形成される。この隙間Ｓ２の寸法は、外観意匠性を考慮すると０．５ｍｍ以下とすることが好ましく、また、外板１０および枠部材２０の組み立て時の寸法で生じるばらつき（嵌め合い公差）を考慮すると０．５ｍｍ±０．５ｍｍ程度が好ましい。この隙間Ｓ２により、外板１０及び枠部材２０の組み立て時の寸法で生じるばらつき（嵌め合い公差）を吸収することができる。 A gap S2 is formed between the proximal surface 21e2 and the end surface of the outer plate 10. As shown in FIG. The dimension of this gap S2 is preferably set to 0.5 mm or less in consideration of appearance design. About 5 mm±0.5 mm is preferable. This gap S2 can absorb variation (fitting tolerance) that occurs in the dimensions of the outer plate 10 and the frame member 20 when assembled.

また、溝部２１ｆの前後方向の寸法は、隙間Ｓ２よりも大きいことが望ましい。これにより、フランジ部２１ａと外板１０との間から流出した接着剤７０が溝部２１ｆに溜まり、隙間Ｓ２から外板１０の表面側に漏れ出ることを抑制できる。 Moreover, it is desirable that the dimension of the groove portion 21f in the front-rear direction is larger than the gap S2. As a result, the adhesive agent 70 flowing out from between the flange portion 21a and the outer plate 10 can be prevented from remaining in the groove portion 21f and leaking to the surface side of the outer plate 10 through the gap S2.

また、溝部２１ｆの前後方向の寸法は、外板１０の厚み寸法よりも小さい。換言すると、近接面２１ｅ２と外板１０の端面との少なくとも一部が前後方向にラップしている。これにより、使用者から溝部２１ｆを見え難くすることができる。 Moreover, the dimension of the groove portion 21f in the front-rear direction is smaller than the thickness dimension of the outer plate 10 . In other words, at least a portion of the proximity surface 21e2 and the end surface of the outer plate 10 overlap in the front-rear direction. This makes it difficult for the user to see the groove 21f .

さらにこのとき、近接面２１ｅ２の少なくとも一部が、外板１０の端面の内、面取り部１０ａが形成されていない端面と対向する。これにより、使用者から溝部２１ｆをさらに見え難くすることができ、意匠性を向上できる。 Furthermore, at this time, at least a portion of the proximity surface 21e2 faces the end surface of the outer plate 10 where the chamfered portion 10a is not formed. As a result, the groove 21f can be made more difficult to see from the user, and the design can be improved.

図６は、図１のIV－IV線断面図である。 FIG. 6 is a cross-sectional view taken along line IV--IV of FIG.

図６に示すように、下側枠部材２４は、表裏方向（冷蔵庫１の前後方向）に沿って延びる板状の本体部２４ｂを有している。本体部２４ｂには、外板１０側に沿い、かつ、本体部２４ｂに直交して延びるフランジ部２４ａが形成されている。このフランジ部２４ａは、下側枠部材２４の表側の略端部に位置している。また、本体部２４ｂには、フランジ部２１ａと平行に延びる補強リブ２４ｃが形成されている。また、図示していないが図４と同様に、フランジ部２４ａの端部とリブ２４ｄの間に接着剤７０が塗布され、外板１０が接着・固定される。 As shown in FIG. 6, the lower frame member 24 has a plate-shaped main body portion 24b extending along the front and back direction (the front-rear direction of the refrigerator 1). The body portion 24b is formed with a flange portion 24a that extends along the outer plate 10 side and perpendicularly to the body portion 24b. The flange portion 24 a is positioned substantially at the front end portion of the lower frame member 24 . A reinforcing rib 24c extending parallel to the flange portion 21a is formed on the body portion 24b. Also, although not shown, similarly to FIG. 4, an adhesive 70 is applied between the end of the flange portion 24a and the rib 24d, and the outer plate 10 is adhered and fixed.

下側枠部材２４は、本体部２４ｂから表面側に延びて、外板１０の端面を覆う前延部２４ｅが一体に形成されている。このとき、外板１０の端面と前延部２４ｅとの間の隙間Ｓ３の寸法は小さいことが好ましい。隙間Ｓ３の寸法は、外板１０及び枠部材２０の組み立て時の寸法で生じるばらつき（嵌め合い公差）を考慮して０．５ｍｍ以下が好ましく、外観意匠性を考慮すると０に近しい方がより好ましい。尚、外板１０及び枠部材２０の組み立て時、外板１０の端面は、内側枠部材２２の前延部２２ｅ及び下側枠部材２４の前延部２４ｅ側に寄せて位置決めされる。 The lower frame member 24 is integrally formed with a front extending portion 24e that extends from the main body portion 24b toward the surface side and covers the end face of the outer plate 10. As shown in FIG. At this time, it is preferable that the dimension of the gap S3 between the end face of the outer plate 10 and the forward extension portion 24e is small. The dimension of the gap S3 is preferably 0.5 mm or less in consideration of the variation (fitting tolerance) that occurs in the dimensions of the outer plate 10 and the frame member 20 when assembled, and is more preferably close to 0 in consideration of the appearance design. . When the outer plate 10 and the frame member 20 are assembled, the end surface of the outer plate 10 is positioned closer to the forwardly extending portion 22e of the inner frame member 22 and the forwardly extending portion 24e of the lower frame member 24 side.

前延部２４ｅの板厚は、本体部２４ｂの板厚よりも薄く形成されている。また、断熱扉４ａと上下方向に隣接する本体部２４ｂの表面２４ｂ１と、前延部２４ｅの表面２４ｅ１とは、面一となるように構成されている。 The plate thickness of the forward extension portion 24e is formed to be thinner than the plate thickness of the main body portion 24b. A surface 24b1 of the body portion 24b vertically adjacent to the heat insulating door 4a and a surface 24e1 of the forward extending portion 24e are configured to be flush with each other.

以上、本実施の形態では、前延部２４ｅの端部２４ｅ１を、外板１０の表面よりも前方に突出させたことで、外板１０の端面に対する衝撃から保護できるとともに、外板１０の表面を広く見せることができ意匠性を向上することができる。 As described above, in the present embodiment, the end portion 24e1 of the front extending portion 24e projects forward beyond the surface of the outer plate 10, thereby protecting the end surface of the outer plate 10 from impact and can be made to appear wider and the design can be improved.

外板１０の表面よりも手前側に露出した端部２４ｅ１の寸法ｔ４は０．２～１．０ｍｍ程度が好ましい。これにより、外板２４と上下方向に隣接する断熱扉４ａを開放して貯蔵室内の食品を取り出す際に食品が端部２４ｅ１に接触し難くい。また、前延部２４ｅの上面部に埃が溜まり難くなる。また、前延部２４ｅの上面部に、外板１０から端部２４ｅ１にかけて低くなる傾斜部２４ｅ２を設けた。外板１０の表面を伝って水滴が前延部２４ｅに降りてきた場合、その水滴が外板１０と前延部２４ｅとの間に溜まり難くし、外板１０と前延部２４ｅとの間の隙間Ｓ３から水が外板１０の裏面側に浸入することを抑制し、外板１０の裏面に施された塗料層が水の影響で腐食することを抑制できる。また、使用者の目線は傾斜部２４ｅ２を斜め上方から見るため、外板１０と傾斜部２４ｅ２とが連続した面のように表現でき、外板１０の表面を大きく見せることができ外観意匠性を向上することができる。 The dimension t4 of the end portion 24e1 exposed on the front side of the surface of the outer plate 10 is preferably about 0.2 to 1.0 mm. As a result, food is less likely to come into contact with the end portion 24e1 when the heat-insulating door 4a vertically adjacent to the outer plate 24 is opened to take out food from the storage compartment. In addition, dust is less likely to accumulate on the upper surface of the forward extending portion 24e. In addition, an inclined portion 24e2 that is lowered from the outer plate 10 to the end portion 24e1 is provided on the upper surface portion of the forward extension portion 24e. When water droplets come down on the front extension part 24e along the surface of the outer plate 10, the water droplets are made difficult to accumulate between the outer plate 10 and the front extension part 24e, and Infiltration of water to the back surface side of the outer plate 10 from the gap S3 can be suppressed, and corrosion of the paint layer applied to the back surface of the outer plate 10 due to the influence of water can be suppressed. In addition, since the user's line of sight is to look at the inclined portion 24e2 obliquely from above, the outer plate 10 and the inclined portion 24e2 can be represented as if they were a continuous surface, and the surface of the outer plate 10 can be made to appear larger, thereby enhancing the appearance design. can be improved.

尚、上側枠部材２３は、内側枠部材２２や下側枠部材２４とほぼ同様の構成の箇所の説明は省略する。 The upper frame member 23 has substantially the same configuration as the inner frame member 22 and the lower frame member 24, and the description thereof will be omitted.

上側枠部材２３は、本体部２３ｂから表面側に延びて、外板１０の端面を覆う前延部２３ｅが一体に形成されている。前延部２３ｅの前端は外板１０の表面よりも前後方向の後方に位置している。 The upper frame member 23 is integrally formed with a front extending portion 23e that extends from the main body portion 23b to the surface side and covers the end surface of the outer plate 10. As shown in FIG. The front end of the forward extending portion 23e is positioned behind the surface of the outer plate 10 in the front-rear direction.

上側枠部材２３は、内側枠部材２２や下側枠部材２４と異なり、冷蔵庫１の正面側に立った使用者の目線よりも上方に位置するため目視され難い。そのため、上側枠部材２３と外板１０の端面との間の隙間Ｓ４の寸法は、外板１０及び枠部材２０の組み立て時の寸法で生じるばらつき（嵌め合い公差）を考慮して０．５ｍｍ±０．５ｍｍ程度とすることが好ましい。 Unlike the inner frame member 22 and the lower frame member 24, the upper frame member 23 is located above the line of sight of the user standing in front of the refrigerator 1, and thus is difficult to see. Therefore, the dimension of the gap S4 between the upper frame member 23 and the end face of the outer plate 10 is set to 0.5 mm±0.5 mm in consideration of the variation (fitting tolerance) that occurs in the dimensions when the outer plate 10 and the frame member 20 are assembled. It is preferable to set it to about 0.5 mm.

図７は、ガラスの詳細な構成を示す断面図であり、本実施の形態では図４と同じ断面箇所を例に説明するが、図５及び図６の断面箇所も同様の構成である。 FIG. 7 is a cross-sectional view showing the detailed structure of the glass. In this embodiment, the same cross-sectional area as in FIG. 4 will be described as an example, but cross-sectional areas in FIGS. 5 and 6 also have the same configuration.

図７に示すように、ガラス製の外板１０の裏面には、隠蔽性を持たせるための有色の塗料層８０が塗布されている（形成されている）。これにより、裏面側の発泡断熱材５０（図３参照）が正面側から見えないように処理されるので、外観性の優れた断熱扉２ａ（図３参照）を得ることができる。なお、外板１０の裏面には、塗料層８０に替えて鏡面処理が施されていてもよい。 As shown in FIG. 7, a colored paint layer 80 is applied (formed) on the rear surface of the outer plate 10 made of glass to provide concealment. As a result, the heat insulating foam material 50 (see FIG. 3) on the back side is processed so that it cannot be seen from the front side, so that the heat insulating door 2a (see FIG. 3) with excellent appearance can be obtained. The rear surface of the outer plate 10 may be mirror-finished instead of the paint layer 80 .

また、塗料層８０の裏面には、さらに飛散防止フィルム９０が貼り付けられている。この飛散防止フィルム９０は、ガラス製の外板１０に衝撃が加えられて外板１０が割れた場合や亀裂が入った場合であっても、外板１０が周囲に飛び散らないように保護できるものである。 Moreover, a scattering prevention film 90 is attached to the back surface of the paint layer 80 . The anti-scattering film 90 can protect the outer plate 10 from being scattered around even if the outer plate 10 made of glass is shattered or cracked due to an impact. is.

飛散防止フィルム９０は、外板１０の裏面に配置された樹脂製の薄膜状の部材である。また、飛散防止フィルム９０は、フィルム状の部材であれば、その材質は特に限定されない。飛散防止フィルム９０は、例えば、その一例を挙げると、ポリエステルフィルム（ＰＥＴフィルム）が挙げられる。そのＰＥＴフィルムは、強度が高くガラスが割れた際の飛散防止にも効果がある。また、ＰＥＴフィルムは、透明性が高く、飛散防止フィルム９０の基材の背面に印刷を施すことにより、フィルムを通して塗料層８０が見えるので、光沢が出て高級感がある意匠性の高い装飾シートとすることが可能である。また、ＰＥＴフィルムは、耐熱・耐寒性に優れており、発泡断熱材５０（図３参照）の充填時の高温に対して、塗料層を保護できるとともに、外板１０から伝達される外気温の影響が少ない。 The anti-scattering film 90 is a resin-made thin-film member arranged on the back surface of the outer plate 10 . The material of the anti-scattering film 90 is not particularly limited as long as it is a film-like member. The anti-scattering film 90 is, for example, a polyester film (PET film). The PET film has a high strength and is effective in preventing scattering when the glass is broken. In addition, the PET film has high transparency, and by printing on the back surface of the base material of the anti-scattering film 90, the paint layer 80 can be seen through the film. It is possible to In addition, the PET film is excellent in heat resistance and cold resistance, and can protect the paint layer from the high temperature at the time of filling the foam insulation material 50 (see FIG. 3). less impact.

図７に示す実施形態では、飛散防止フィルム９０と内側枠部材２２とが接着剤７０を介して固定される。この場合、貼り付ける前の飛散防止フィルム９０がロール状に巻回されたものであれば、基材と、基材の一面側に形成される粘着層（接着層）と、他面側に形成されるフッ素コーティングした離型材とが積層されて構成されているものである。塗料層８０の上にフィルムを貼り付ける場合には、ロール状の飛散防止フィルム９０から繰り出して、粘着層の側が塗料層８０に貼り付けられる。一方、飛散防止フィルム９０の離型材と接着剤７０とが接触することになり、外板１０と内側枠部材２２との接着性が損なわれることになる（付きが悪くなる）。本実施形態では、飛散防止フィルム９０を塗料層８０に貼り付ける場合には、特にフッ素系コーティングされた離型材を含まないものを使用することが好ましい。なお、外板１０に飛散防止フィルム９０のみを設ける場合も、フッ素コーティングされた離型材を含まないものを使用することが好ましい。 In the embodiment shown in FIG. 7 , the anti-scattering film 90 and the inner frame member 22 are fixed via an adhesive 70 . In this case, if the anti-scattering film 90 before pasting is wound in a roll, the substrate, the adhesive layer (adhesive layer) formed on one side of the substrate, and the other side Fluorine-coated mold release material is laminated. When a film is attached on the paint layer 80 , the adhesive layer side is attached to the paint layer 80 by unrolling it from the roll-shaped anti-scattering film 90 . On the other hand, the release material of the anti-scattering film 90 and the adhesive 70 come into contact with each other, and the adhesiveness between the outer plate 10 and the inner frame member 22 is impaired (stickiness deteriorates). In the present embodiment, when the anti-scattering film 90 is attached to the paint layer 80, it is particularly preferable to use one that is coated with fluorine and does not contain a release material. Even when only the anti-scattering film 90 is provided on the outer plate 10, it is preferable to use a fluorine-coated release material that does not contain the release material.

また、外板１０には、塗料層８０と飛散防止フィルム９０の双方を設ける構成に限定されるものではなく、塗料層８０のみを設けるものであってもよい。外板１０に塗料層８０のみを設ける場合にも、塗料層８０にフッ素を含まないものを使用することが好ましい。 Further, the outer panel 10 is not limited to the configuration in which both the paint layer 80 and the anti-scattering film 90 are provided, and the outer panel 10 may be provided with only the paint layer 80 . Even when only the coating layer 80 is provided on the outer panel 10, it is preferable to use a coating layer 80 that does not contain fluorine.

ところで、ＰＵＲのホットメルトは、硬化したときに、熱収縮を受け易くなるので、引張り力（ヤング率）が高くなる。このため、引張り力が、塗料層８０と外板１０との密着力よりも強くなり、塗料層８０を引き剥がすおそれがある。そこで、ＰＵＲを使用する場合には、外板１０に塗料層８０だけを設けるのではなく、塗料層８０の上にさらに飛散防止フィルム９０を設けることが好ましい。また、塗料層８０の上（反外板１０側）若しくは塗料層８０の代わりに、塗料層やヘアーライン等の模様層が施された樹脂フィルム（図示せず）を設けてもよい。 By the way, when PUR hot melt is cured, it is susceptible to heat shrinkage, so that it has a high tensile strength (Young's modulus). Therefore, the tensile force becomes stronger than the adhesive force between the paint layer 80 and the outer plate 10, and there is a risk that the paint layer 80 will be peeled off. Therefore, when PUR is used, it is preferable not only to provide the paint layer 80 on the outer plate 10 but also to provide the anti-scattering film 90 on the paint layer 80 . Also, a resin film (not shown) having a pattern layer such as a paint layer or a hairline may be provided on the paint layer 80 (on the side opposite to the outer panel 10 ) or instead of the paint layer 80 .

ここで、塗料層８０と接着剤７０が直接接着していると、接着剤７０自体が固化して収縮する際に、接着剤７０が塗料層８０を引っ張り、外板１０から塗料層８０を剥がしてしまう可能性がある。そこで、本実施形態では、飛散防止フィルム９０の貼付け位置を、塗料層８０よりも内側かつリブ２２ｄよりも外側まで延ばしている。 Here, if the paint layer 80 and the adhesive 70 are directly adhered to each other, the adhesive 70 pulls the paint layer 80 when the adhesive 70 itself solidifies and shrinks, and the paint layer 80 is peeled off from the outer panel 10. There is a possibility that Therefore, in this embodiment, the sticking position of the anti-scattering film 90 is extended inside the paint layer 80 and outside the ribs 22d.

図８は、引出式の断熱扉を正面側から見たときの斜視図である。以下では、冷蔵室２の回転式の断熱扉２ａに代えて、製氷室３の引出式の断熱扉３ａを参照して説明する。また、本実施の形態では、断熱扉３ａの説明をしているが、左右方向に並んで設けられた断熱扉４ａは左右対称の構成のため、断熱扉４ａの説明は省略する。 FIG. 8 is a perspective view of the drawer-type heat insulating door when viewed from the front side. In the following description, the drawer-type heat-insulating door 3a of the ice making chamber 3 is referred to instead of the rotating heat-insulating door 2a of the refrigerating chamber 2. FIG. In this embodiment, the heat insulating door 3a is described, but the heat insulating door 4a arranged in the left-right direction is bilaterally symmetrical, so the description of the heat insulating door 4a is omitted.

図８に示すように、引出式の断熱扉３ａは、回転式の断熱扉２ａ（図１参照）と同様に、ガラス製の外板１０Ａと、扉枠２０Ａと、内板６０Ａと、を備えて構成されている。 As shown in FIG. 8, the pull-out heat insulating door 3a includes an outer plate 10A made of glass, a door frame 20A, and an inner plate 60A, similar to the rotary heat insulating door 2a (see FIG. 1). configured as follows.

扉枠２０Ａは、外板１０Ａの周縁に設けられた四角形状の枠材である。扉枠２０Ａは、前記した回動式の断熱扉２ａの扉枠２０（図２参照）と同様、外側枠部材２１Ａ（垂直枠部材）と、内側枠部材２２Ａ（垂直枠部材）と、上側枠部材２３Ａ（水平枠部材）と、下側枠部材２４Ａ（水平枠部材）とを横長の矩形状に連結して構成されている。上側枠部材２３Ａには、利用者が開閉する際に手を掛けるための手掛部２３Ａ１が形成されている。また、図２に示す回転式の断熱扉２ａ、２ｂと同様に、引出式の断熱扉３ａ、４ａの外板１０Ａの周囲四辺の端面は、夫々枠部材２１Ａ、２２Ａ、２３Ａ、２４Ａにより覆われ、周囲四辺の前面は覆われない構成となっている。 20 A of door frames are square-shaped frame members provided in the peripheral edge of 10 A of outer plates. The door frame 20A includes an outer frame member 21A (vertical frame member), an inner frame member 22A (vertical frame member), and an upper frame member, similar to the door frame 20 (see FIG. 2) of the rotary heat insulating door 2a. A member 23A (horizontal frame member) and a lower frame member 24A (horizontal frame member) are connected in a horizontally long rectangular shape. The upper frame member 23A is formed with a handle portion 23A1 for the user to hold when opening and closing. Similarly to the rotary type heat insulating doors 2a and 2b shown in FIG. 2, the edge surfaces of the four sides of the outer plate 10A of the drawer type heat insulating doors 3a and 4a are covered with frame members 21A, 22A, 23A and 24A, respectively. , and the four sides of the front surface are not covered.

尚、外板１０Ａ及び枠部材２０Ａの組み立て時、外板１０Ａの端面は、内側枠部材２２Ａ及び上側枠部材２４Ａ側に寄せて位置決めされる。 When assembling the outer plate 10A and the frame member 20A, the end surface of the outer plate 10A is positioned closer to the inner frame member 22A and the upper frame member 24A.

図９は、図１のＶ－Ｖ線断面図である。 FIG. 9 is a cross-sectional view taken along line VV of FIG.

図９に示すように、上側枠部材２３Ａは凹形状の手掛部２３Ａ１が形成される。この手掛部２３Ａ１の外板１０Ａ側の面に接着剤７０が塗布され、外板１０Ａを貼り付ける。即ち、図６に示す上側枠部材２３に備えたフランジ部２３ａと同等の役割を果す。 As shown in FIG. 9, the upper frame member 23A is formed with a recessed handle portion 23A1. An adhesive 70 is applied to the surface of the handle portion 23A1 facing the outer panel 10A, and the outer panel 10A is adhered thereto. That is, it plays the same role as the flange portion 23a provided on the upper frame member 23 shown in FIG.

また、手掛部２３Ａ１の外板１０Ａ側の面には、リブ２３Ａ２及び溝部２３Ａ３が設けられる。リブ２３Ａ３は、フランジ部２３ｄ等と同等の役割を果すものであり説明は省略する。溝部２３Ａ２は、外板１０Ａの反端面側に設けられる。これにより、樹脂の肉厚差が生じる箇所の付近にヒケが発生することを抑制し、接着剤７０の塗布面の平面度を高めている。また、余分な接着剤７０が溝部２３Ａ２に流れ込むことで、発泡断熱材５０Ａ側に接着剤７０が侵入することを抑制する。 A rib 23A2 and a groove 23A3 are provided on the surface of the handle 23A1 facing the outer plate 10A. The rib 23A3 plays the same role as the flange portion 23d and the like, and the description thereof is omitted. The groove portion 23A2 is provided on the opposite end face side of the outer plate 10A. As a result, it is possible to suppress the occurrence of sink marks in the vicinity of the portion where the thickness difference of the resin occurs, and to improve the flatness of the surface on which the adhesive 70 is applied. Moreover, the excess adhesive 70 flows into the groove portion 23A2, thereby suppressing the penetration of the adhesive 70 into the foamed heat insulating material 50A side.

また、上側枠部材２３Ａの前端部（図６に示す近接部２３ｅに相当）は、外板１０Ａの表面よりも後方に位置している。外板１０Ａの端面と上側枠部材２３Ａとの間に隙間Ｓ４Ａが設けられる。 Also, the front end portion of the upper frame member 23A (corresponding to the proximity portion 23e shown in FIG. 6) is located behind the surface of the outer plate 10A. A gap S4A is provided between the end surface of the outer plate 10A and the upper frame member 23A.

また、下側枠部材２４Ａの前端部（図６に示す近接部２４ｅに相当）は、外板１０Ａの表面よりも前方に位置している。外板１０Ａの端面と下側枠部材２４Ａとの間に隙間Ｓ３Ａが設けられる。また、下側枠部材２４Ａは、フランジ部２４ａ、リブ２４ｄ等と同様の構成を備えているが図示せず、説明は省略する。 Also, the front end portion of the lower frame member 24A (corresponding to the proximity portion 24e shown in FIG. 6) is located forward of the surface of the outer plate 10A. A gap S3A is provided between the end surface of the outer plate 10A and the lower frame member 24A. Also, the lower frame member 24A has the same configuration as the flange portion 24a, the ribs 24d, etc., but is not illustrated and will not be described.

図１０は図１のVI－VI線断面図である。 FIG. 10 is a sectional view taken along line VI-VI of FIG.

図１０に示すように、冷蔵庫１の幅方向の全幅に設けられた引出式の断熱扉５ａは、垂直枠部材２５、２６の係合溝２５ａ、２６ａが、外板１０Ｂの左右の端面が挿入される凹状溝から成る。これにより、外板１０Ｂの左右の端面及び前面は垂直枠部材２５，２６により覆う構成とした。尚、断熱扉６ａも同様の構造のため説明は省略する。 As shown in FIG. 10, a drawer-type heat insulating door 5a provided over the entire width of the refrigerator 1 has engaging grooves 25a and 26a of the vertical frame members 25 and 26, and left and right end faces of the outer plate 10B are inserted. consists of a recessed groove As a result, the right and left end surfaces and the front surface of the outer plate 10B are covered with the vertical frame members 25 and 26. As shown in FIG. Since the heat insulating door 6a has the same structure, the explanation is omitted.

図３，図４，図５に示すように、断熱扉２ａ，２ｂは、外板１０の左右の端面を枠部材２１，２２（近接部２１ｅ，２２ｅ）で覆い、外板１０の左右の前面は枠部材２１，２２で覆わない構成とした。 As shown in FIGS. 3, 4, and 5, the heat-insulating doors 2a and 2b cover the left and right end surfaces of the outer plate 10 with frame members 21 and 22 (proximal portions 21e and 22e), and the left and right front surfaces of the outer plate 10. is not covered with the frame members 21 and 22.

また、使用者の目線に近い冷蔵庫１の上部に設けられた断熱扉２ａ，２ｂは、その組み立て時に生じる、外板１０の左右の端面と左右の枠部材２１，２２との間に形成される各隙間Ｓ１，Ｓ２の寸法は、隙間Ｓ２（外側枠部材２１側）＞隙間Ｓ１（内側枠部材２２側）とした。 Also, the heat insulation doors 2a, 2b provided on the upper part of the refrigerator 1 close to the line of sight of the user are formed between the left and right end faces of the outer plate 10 and the left and right frame members 21, 22, which are generated during assembly. The dimensions of the gaps S1 and S2 were set to the gap S2 (on the side of the outer frame member 21)>the gap S1 (on the side of the inner frame member 22).

これにより、左右に隣接する断熱扉２ａ，２ｂの各外板１０の位置は、互いに内側（反回転軸側）に寄っているため、該各外板１０の内側枠部材２２側の端面の間の距離を小さくでき、左右方向に連続した一体的なガラス面のように表現することができる。即ち、冷蔵庫の正面に立つ使用者の目線から近い冷蔵庫１の中心側の隙間Ｓ１を目立ち難くすることで、外観意匠性を向上できる。また、外板１０端面の間の距離が小さいことで、外板１０表面の清掃性が向上する。 As a result, the positions of the outer plates 10 of the heat-insulating doors 2a and 2b adjacent to each other on the left and right sides are closer to each other (opposite to the rotating shaft side), so that the end faces of the outer plates 10 on the inner frame member 22 side can be reduced, and can be represented as an integral glass surface that is continuous in the left-right direction. That is, by making the gap S1 on the center side of the refrigerator 1, which is close to the line of sight of the user standing in front of the refrigerator, inconspicuous, the appearance design can be improved. In addition, since the distance between the end surfaces of the outer plate 10 is small, the cleanability of the surface of the outer plate 10 is improved.

また、図８に示す断熱扉３ａ，４ａも左右に隣接し、外板１０Ａの左右の端面を枠部材２１Ａ，２２Ａで覆い、外板１０Ａの左右の前面は枠部材２１Ａ，２２Ａで覆わない構成のため、上述の断熱扉２ａ，２ｂと同様に、隙間Ｓ２Ａ（外側枠部材２１Ａ側）＞隙間Ｓ１Ａ（内側枠部材２２Ａ側）とするのが好ましい。 In addition, the heat insulating doors 3a and 4a shown in FIG. 8 are also adjacent to each other on the left and right, and the left and right end surfaces of the outer plate 10A are covered with the frame members 21A and 22A, and the left and right front surfaces of the outer plate 10A are not covered with the frame members 21A and 22A. Therefore, it is preferable to set the gap S2A (on the side of the outer frame member 21A)>the gap S1A (on the side of the inner frame member 22A), as in the heat insulating doors 2a and 2b described above.

また、回転扉である断熱扉２ａ，２ｂは、回転軸側（外側枠部材２１側）よりも、手掛部（図示せず）が設けられる反回転軸側（内側枠部材２２側）に、開放動作時の回転モーメントがかかる。そこで、外板１０の左右方向の取り付け位置を、内側枠部材２２寄り（即ち、隙間Ｓ２＞隙間Ｓ１）とすることで、フランジ部２２ａに塗布された接着剤７０との接触面積を大きくでき、外板１０の剥がれを抑制できる。 In addition, the heat insulating doors 2a and 2b, which are rotating doors, are arranged on the opposite side of the rotating shaft (the side of the inner frame member 22) where the handle (not shown) is provided rather than the side of the rotating shaft (the side of the outer frame member 21). Rotational moment is applied during opening operation. Therefore, by setting the mounting position of the outer plate 10 in the left-right direction to the side of the inner frame member 22 (that is, the gap S2>the gap S1), the contact area with the adhesive 70 applied to the flange portion 22a can be increased. Peeling of the outer plate 10 can be suppressed.

図６に示すように、断熱扉２ａ，２ｂは、外板１０の上下の端面を枠部材２３，２４で覆い、外板１０の上下の前面は枠部材２３，２４で覆わない構成となっている。また、断熱扉２ａ，２ｂは、その組み立て時に生じる、外板１０の上下の端面と上下の枠部材２３，２４との間に形成される各隙間Ｓ３，Ｓ４の寸法は、隙間Ｓ４（上側枠部材２３側）＞隙間Ｓ３（下側枠部材２４側）とした。 As shown in FIG. 6, the heat insulating doors 2a and 2b are configured such that the upper and lower end surfaces of the outer plate 10 are covered with frame members 23 and 24, and the upper and lower front surfaces of the outer plate 10 are not covered with the frame members 23 and 24. there is In addition, the dimensions of the gaps S3 and S4 formed between the upper and lower end surfaces of the outer plate 10 and the upper and lower frame members 23 and 24, which are generated during the assembly of the heat insulating doors 2a and 2b, are equal to the gap S4 (upper frame member 23 side)>gap S3 (lower frame member 24 side).

これにより、冷蔵庫１の上方に位置し且つ、上下方向に長い矩形状の断熱扉２ａ，２ｂにおいて、使用者が冷蔵庫１の正面に立ったときに、その目線から近い隙間Ｓ３を目立ち難くでき、意匠性を向上できる。 As a result, in the rectangular heat insulating doors 2a and 2b positioned above the refrigerator 1 and elongated in the vertical direction, when the user stands in front of the refrigerator 1, the gap S3 close to the user's line of sight can be made inconspicuous. Designability can be improved.

また、外板１０の端面には面取り部１０ａが形成されている。この外板１０の表面側に形成された面取り部１０ａが、上側枠部材２３の近接部２３ｅの前端部よりも前方に位置する。
このとき、冷蔵庫１の正面に立つ使用者の目線は、上側枠部材２３を下方から見上げることになる。即ち、外板１０の上辺側の端面によって隙間Ｓ４を隠し、使用者から見え難くすることができ、意匠性を向上できる。 A chamfered portion 10a is formed on the end face of the outer plate 10. As shown in FIG. The chamfered portion 10a formed on the surface side of the outer plate 10 is located forward of the front end portion of the adjacent portion 23e of the upper frame member 23. As shown in FIG.
At this time, the line of sight of the user standing in front of the refrigerator 1 looks up at the upper frame member 23 from below. That is, the gap S4 can be hidden by the end face on the upper side of the outer plate 10, making it difficult for the user to see, and the design can be improved.

図９に示すように、断熱扉２ａ，２ｂは、外板１０の上下の端面を枠部材２３，２４で覆い、外板１０の上下の前面は枠部材２３，２４で覆わない構成となっている。また、断熱扉３ａ，４ａは、その組み立て時に生じる、外板１０Ａの上下の端面と上下の枠部材２３Ａ，２４Ａとの間に形成される各隙間Ｓ３Ａ，Ｓ４Ａの寸法は、隙間Ｓ３Ａ（下側枠部材２４Ａ側）＞隙間Ｓ４Ａ（上側枠部材２３Ａ側）とした。 As shown in FIG. 9, the heat insulating doors 2a and 2b are configured such that the upper and lower end surfaces of the outer plate 10 are covered with frame members 23 and 24, and the upper and lower front surfaces of the outer plate 10 are not covered with the frame members 23 and 24. there is In addition, the dimensions of the gaps S3A and S4A formed between the upper and lower end surfaces of the outer plate 10A and the upper and lower frame members 23A and 24A, which are generated during the assembly of the heat insulating doors 3a and 4a, are the gaps S3A (lower side frame member 24A side)>gap S4A (upper frame member 23A side).

これにより、冷蔵庫１の上下方向の中央付近に位置する断熱扉３ａ，４ａにおいて、使用者が冷蔵庫１の正面に立ったときに、その目線から近い隙間Ｓ４Ａを目立ち難くでき、意匠性を向上できる。 Thus, in the heat insulating doors 3a and 4a positioned near the center in the vertical direction of the refrigerator 1, when the user stands in front of the refrigerator 1, the gap S4A close to the line of sight of the user can be made inconspicuous, and the design can be improved. .

また、外板１０Ａの外周には面取り部（面取り部１０ａと同等の構成につき図示せず。）が形成されている。この外板１０Ａの外周に形成された面取り部が、上側枠部材２３Ａの近接部２３Ａｅの前端部よりも前方に位置する。このとき、冷蔵庫１の正面に立つ使用者の目線は、上側枠部材２３Ａを上方から見下ろすことになる。即ち、使用者に対して、外板１０Ａの上辺側の端面（面取り部）を見せつつ、隙間Ｓ４Ａを見え難くすることができ、意匠性を向上できる。 A chamfered portion (not shown because it has the same configuration as the chamfered portion 10a) is formed on the outer periphery of the outer plate 10A. The chamfered portion formed on the outer periphery of the outer plate 10A is positioned forward of the front end portion of the adjacent portion 23Ae of the upper frame member 23A. At this time, the line of sight of the user standing in front of the refrigerator 1 looks down on the upper frame member 23A from above. That is, it is possible to make the gap S4A difficult to see while showing the end surface (chamfered portion) of the upper side of the outer plate 10A to the user, thereby improving the design.

図１０に示すように、断熱扉５ａ，６ａは、外板１０Ｂの左右の端面及び左右の前面を枠部材２５，２６で覆う構成とした。具体的には、外板１０Ｂの左右の端面及び左右の前面を、枠部材２５，２６の手前側に延出して設けられた断面コ字形状の係合溝２５ａ、２６ａに挿入した。 As shown in FIG. 10, the heat insulating doors 5a and 6a are configured such that the left and right end surfaces and the left and right front surfaces of the outer plate 10B are covered with frame members 25 and 26. As shown in FIG. Specifically, the left and right end surfaces and the left and right front surfaces of the outer plate 10B were inserted into the engaging grooves 25a and 26a having a U-shaped cross section and extending toward the front side of the frame members 25 and 26, respectively.

また、冷蔵庫１の下方に位置する断熱扉５ａ，６ａは、冷蔵庫１の左右の幅方向に対して全幅で且つ、横長の矩形状に設けられている。このように、断熱扉５ａ，６ａが横長形状であり、その左右方向の寸法が大きくなる程、外板１０Ｂと枠部材２０Ｂとの組み立て時に生じる寸法公差の影響が大きくなり、外板１０Ｂの左右の端面と枠部材２５，２６との間の隙間の大きさに偏りが生じ易くなる。 Moreover, the heat insulation doors 5a and 6a positioned below the refrigerator 1 are provided in a horizontally long rectangular shape having a full width with respect to the left and right width directions of the refrigerator 1 . In this way, the heat insulating doors 5a and 6a are oblong in shape, and the larger the dimension in the left-right direction, the greater the influence of the dimensional tolerance that occurs when the outer plate 10B and the frame member 20B are assembled. gaps between the end faces of the frame members 25 and 26 and the frame members 25 and 26 are likely to be biased.

そこで、断熱扉５ａ，６ａの外板１０Ｂの左右の端面及び左右の前面を枠部材２５，２６で覆って使用者から見えないようにする。これにより、外板１０Ｂの左右の隙間の寸法の偏りによって生じる外観意匠性の低下を、抑制することができる。 Therefore, the left and right end surfaces and the left and right front surfaces of the outer plate 10B of the heat insulating doors 5a and 6a are covered with frame members 25 and 26 so as not to be seen by the user. As a result, it is possible to suppress deterioration in the appearance design property caused by unevenness in the dimensions of the left and right gaps of the outer plate 10B.

また、断熱扉５ａ，６ａの外板１０Ｂの左右を係合溝２５ａ，２６ａで覆うように支持したことで、外板１０Ｂが、外部からの衝撃や接着剤７０の劣化等により落下することを抑制できる。 In addition, by covering the left and right sides of the outer plate 10B of the heat insulating doors 5a and 6a with the engagement grooves 25a and 26a, the outer plate 10B can be prevented from falling due to an external impact, deterioration of the adhesive 70, or the like. can be suppressed.

尚、図１，図３に示すように、冷蔵庫１の上方に位置する断熱扉２ａ，２ｂ，３ａ，４ａは、冷蔵庫１の左右の幅方向に対して全幅で設けられていないため、外板１０，１０Ａの左右の前面は枠部材２１，２２，２１Ａ，２２Ａで覆わない構成とした。これは、外板１０，１０Ａの左右方向の幅寸法は小さいため、幅寸法の大きな外板１０Ｂと比べると組み立て時の寸法公差は生じ難いためである。また、外板１０，１０Ａの端面を、左右方向（若しくは上下方向）の一方の枠部材に突き当てるように寄せて取り付けることで、量産品における寸法公差を管理でき、外観意匠性の低下を抑制できる。 As shown in FIGS. 1 and 3, the heat insulating doors 2a, 2b, 3a, and 4a located above the refrigerator 1 are not provided over the entire width in the lateral direction of the refrigerator 1. The left and right front surfaces of 10 and 10A are not covered with frame members 21, 22, 21A and 22A. This is because the width dimension in the left-right direction of the outer plates 10 and 10A is small, so that the dimensional tolerance during assembly is less likely to occur than the outer plate 10B having a large width dimension. In addition, by attaching the end surfaces of the outer plates 10 and 10A so as to abut against one frame member in the left-right direction (or up-down direction), dimensional tolerances in mass-produced products can be controlled, and deterioration in appearance design can be suppressed. can.

また、断熱扉５ａ，６ａは、外板１０Ｂの上下の端面及び上下の前面も枠部材２５，２６で覆う構成とした。具体的には、外板１０Ｂの上下の端面及び上下の前面を、枠部材２５，２６の手前側に延出して設けられた断面コ字形状の係合溝２５ａ、２６ａに挿入した（図１０と同等の構成のため詳細な構成の説明は省略する。）。 The heat insulating doors 5a and 6a are configured such that the upper and lower end surfaces and the upper and lower front surfaces of the outer plate 10B are also covered with the frame members 25 and 26. As shown in FIG. Specifically, the upper and lower end surfaces and the upper and lower front surfaces of the outer plate 10B were inserted into the engaging grooves 25a and 26a having a U-shaped cross section and extending toward the front side of the frame members 25 and 26 (Fig. 10). Since the configuration is the same as that of , detailed description of the configuration is omitted.).

そこで、断熱扉５ａ，６ａの外板１０Ｂの上下の端面及び上下の前面を枠部材２５，２６で覆って使用者から見えないようにする。これにより、外板１０Ｂの上下の隙間の寸法の偏りによって生じる外観意匠性の低下を、抑制することができる。 Therefore, the upper and lower end surfaces and the upper and lower front surfaces of the outer plate 10B of the heat insulating doors 5a and 6a are covered with frame members 25 and 26 so as not to be seen by the user. As a result, it is possible to suppress deterioration in the appearance design property caused by unevenness in the dimensions of the gaps between the upper and lower sides of the outer plate 10B.

また、別の実施形態として、上方貯蔵室として左右に隣接する２枚の回転扉と、下方貯蔵室として左右に隣接する２枚の回転扉と、からなる合計４枚の回転扉からなる冷蔵庫であっても良い。 Further, as another embodiment, a refrigerator having a total of four revolving doors consisting of two revolving doors adjacent to each other on the left and right as an upper storage chamber and two revolving doors adjacent to each other on the left and right as a lower storage chamber.
