以下、本発明の一実施例に係る冷蔵庫について、図１を参照して説明する。図１は、本発明に係る冷蔵庫１の外観を示す正面図である。 Below, a refrigerator according to one embodiment of the present invention will be described with reference to FIG. 1. FIG. 1 is a front view showing the exterior of a refrigerator 1 according to the present invention.

上下方向および左右方向が図１に示すように定義される。上下方向は、冷蔵庫１が水平面に設置された状態において、鉛直方向に一致する。左右方向は水平面に平行で、かつ図１の紙面に平行な方向である。左右方向は、冷蔵庫１の幅方向と一致する。上下方向および左右方向のほか、前後方向が図１の紙面に垂直な方向に定義される。前後方向は、水平面に平行であり、奥行き方向と呼ぶ場合もある。 The up-down direction and the left-right direction are defined as shown in FIG. 1. The up-down direction corresponds to the vertical direction when refrigerator 1 is placed on a horizontal surface. The left-right direction is parallel to the horizontal surface and parallel to the paper surface of FIG. 1. The left-right direction corresponds to the width direction of refrigerator 1. In addition to the up-down direction and the left-right direction, the front-back direction is defined as a direction perpendicular to the paper surface of FIG. 1. The front-back direction is parallel to the horizontal surface and is sometimes called the depth direction.

冷蔵庫１は、上方から冷蔵室２、左右に並設された製氷室３と上段冷凍室４、下段冷凍室５、野菜室６の順番で貯蔵室を有している。冷蔵庫１は、それぞれの貯蔵室の開口を開閉するドアを備えている。これらのドアは、冷蔵室２の開口を開閉する、左右に分割された回転式の冷蔵室ドア２ａ，２ｂと、製氷室３、上段冷凍室４、下段冷凍室５、野菜室６の開口をそれぞれ開閉する引き出し式の製氷室ドア３ａと、上段冷凍室ドア４ａと、下段冷凍室ドア５ａと、野菜室ドア６ａとで構成される。なお、本実施例では、５つの貯蔵室、６つのドアを有する冷蔵庫を例に挙げて説明するが、貯蔵室およびドアの構成は、上述した構成の冷蔵庫に限定される訳ではない。引出式のドアにはそれぞれ、収納容器と、前後に延在するドア側レールが設けられており、冷蔵庫１の内箱８（図２参照）側のレールに例えば摺動可能である。 Refrigerator 1 has storage compartments arranged in the order of refrigerator compartment 2, ice-making compartment 3, upper freezer compartment 4, lower freezer compartment 5, and vegetable compartment 6 from the top. Refrigerator 1 has doors that open and close the openings of each storage compartment. These doors are composed of left and right divided rotating refrigerator compartment doors 2a and 2b that open and close the opening of refrigerator compartment 2, and pull-out ice-making compartment door 3a, upper freezer compartment door 4a, lower freezer compartment door 5a, and vegetable compartment door 6a that open and close the openings of ice-making compartment 3, upper freezer compartment 4, lower freezer compartment 5, and vegetable compartment 6, respectively. In this embodiment, a refrigerator having five storage compartments and six doors will be described as an example, but the configuration of the storage compartments and doors is not limited to the refrigerator with the above-mentioned configuration. Each pull-out door is provided with a storage container and a door side rail extending forward and backward, and can slide, for example, on the rail on the inner box 8 (see FIG. 2) side of refrigerator 1.

冷蔵室２は、庫内を冷蔵温度帯の例えば平均的に４℃程度にした冷蔵貯蔵室である。製氷室３、上段冷凍室４および下段冷凍室５は、庫内を冷凍温度帯の例えば平均的に－１８℃程度にした冷凍貯蔵室である。野菜室６は、庫内を冷蔵温度帯の例えば平均的に６℃程度にした冷蔵貯蔵室で、間接的な冷却により、食品の乾燥を抑えた冷蔵貯蔵室である。 Refrigerator compartment 2 is a refrigerated storage compartment whose interior is kept at a refrigerated temperature range, for example, at an average of about 4°C. Ice-making compartment 3, upper freezer compartment 4, and lower freezer compartment 5 are refrigerated storage compartments whose interior is kept at a freezing temperature range, for example, at an average of about -18°C. Vegetable compartment 6 is a refrigerated storage compartment whose interior is kept at a refrigerated temperature range, for example, at an average of about 6°C, and is a refrigerated storage compartment that prevents food from drying out by indirect cooling.

下段冷凍室５の後側には、各貯蔵室内を冷却する冷却器が配置されている。図示は省略するが、冷却器、圧縮機、凝縮器、およびキャプラリーチューブが接続され、冷凍サイクルが構成される。そして、冷却器の上方には、冷却器にて冷却された冷気を循環させるための送風機が配置され、送風機の下流には貯蔵室内に冷気を吐出する吐出口が形成されている。なお、冷却器は複数あっても良く、配置は下段冷凍室５の後側に限定されるものではなく、冷蔵室２の後側に配置されてもよい。 A cooler is disposed behind the lower freezer compartment 5 to cool the interior of each storage compartment. Although not shown in the figure, the cooler, compressor, condenser, and capillary tube are connected to form a refrigeration cycle. A blower is disposed above the cooler to circulate the cold air cooled by the cooler, and an outlet is formed downstream of the blower to discharge the cold air into the storage compartment. Note that there may be multiple coolers, and their location is not limited to the rear of the lower freezer compartment 5, but may be disposed behind the refrigerator compartment 2.

引出式のドアは、引出式のドアに接続されたドア側のレール（不図示）が内箱８側のレール（不図示）に接続され、内箱８に支持される。引出式のドア又はドア側レールには食品を収納可能な容器が取付けられ、引出式のドアとともに移動する。 The retractable door is supported by the inner box 8, with a door-side rail (not shown) connected to the retractable door being connected to a rail (not shown) on the inner box 8. A container capable of storing food is attached to the retractable door or the door-side rail, and moves together with the retractable door.

冷蔵庫１の本体は、金属製の外箱７と、合成樹脂製の内箱８（図２参照）と、外箱７と内箱８との間に充填された硬質ウレタンフォーム等の発泡断熱材や真空断熱材を含む断熱材と、によって形成される断熱箱体で構成される。 The main body of the refrigerator 1 is composed of an insulated box body formed by a metal outer box 7, an inner box 8 (see Figure 2) made of synthetic resin, and insulation material, including foam insulation material such as rigid urethane foam and vacuum insulation material, filled between the outer box 7 and the inner box 8.

冷蔵室２と、製氷室３および上段冷凍室４とは、略水平な面として配された断熱仕切部１０によって隔てられている。また、下段冷凍室５と野菜室６とは、略水平な面として配された断熱仕切部１１によって隔てられている。これらの断熱仕切部１０，１１は、異なる温度帯の貯蔵室を区画する部分に設けられ、冷凍温度帯室の冷気によって冷蔵温度帯室内が冷え過ぎないようにする役割を果たす。 The refrigerator compartment 2 is separated from the ice-making compartment 3 and the upper freezer compartment 4 by a heat-insulating partition 10 arranged as a substantially horizontal surface. The lower freezer compartment 5 and the vegetable compartment 6 are separated by a heat-insulating partition 11 arranged as a substantially horizontal surface. These heat-insulating partitions 10, 11 are provided in the areas that separate the storage compartments of different temperature zones, and serve to prevent the inside of the refrigerator temperature zone compartment from becoming too cold due to the cold air from the freezer temperature zone compartment.

さらに、外箱７と内箱８との間には、発泡断熱材に加えて、発泡断熱材よりも熱伝導率の低い真空断熱材が実装されることで、食品収納容積を低下させることなく断熱性能が高められている。 Furthermore, in addition to the foam insulation material, vacuum insulation material with a lower thermal conductivity than foam insulation material is installed between the outer box 7 and the inner box 8, improving the insulation performance without reducing the food storage volume.

図２を参照して、冷蔵室２について説明する。図２は、本発明に係る冷蔵庫１の冷蔵室２部分の内箱８を斜め前方から見た斜視図である。 Refrigerator compartment 2 will be described with reference to Figure 2. Figure 2 is a perspective view of inner box 8 of refrigerator compartment 2 of refrigerator 1 according to the present invention, seen obliquely from the front.

冷蔵室２内には、複数の庫内棚７０が設けられる。庫内棚７０は内箱８に形成された棚リブ１３に支持される。複数段の棚リブ１３を選択的に使用することにより、上下に配置される複数の庫内棚７０の間隔が変更可能である。 A number of internal shelves 70 are provided in the refrigerator compartment 2. The internal shelves 70 are supported by shelf ribs 13 formed on the inner box 8. By selectively using the shelf ribs 13 on multiple tiers, the spacing between the multiple internal shelves 70 arranged vertically can be changed.

冷蔵室２の両側面に配された棚リブ１３（図２参照）は、冷蔵庫１の前端から離間したところに前端が位置し、そこから後方に延在している。棚リブ１３には、食品を載置可能な庫内棚７０が載置され、本実施例では複数が上下に並んでいる。 The shelf ribs 13 (see FIG. 2) arranged on both sides of the refrigerator compartment 2 have their front ends located away from the front end of the refrigerator 1 and extend rearward from there. The shelf ribs 13 are used to mount internal shelves 70 on which food can be placed, and in this embodiment, multiple shelves are arranged vertically.

図３乃至図１３を参照して、冷蔵庫１の庫内棚７０について説明する。
図３は、本発明に係る冷蔵庫１の庫内棚７０の外観斜視図である。
庫内棚７０は、略四角形（略長方形）を成す透明なガラス板（載置面部材７１）で構成される載置面７１１と、載置面７１１を取り囲むように設けられた樹脂製の枠部７２と、庫内棚７０の前縁部に設けられた前縁部材７３と、前縁部材７３を固定する固定部材７４と、を備える。 The internal shelf 70 of the refrigerator 1 will be described with reference to Figs. 3 to 13.
FIG. 3 is an external perspective view of an internal shelf 70 of the refrigerator 1 according to the present invention.
The internal shelf 70 comprises a mounting surface 711 composed of a transparent glass plate (mounting surface member 71) forming an approximately quadrangular (approximately rectangular) shape, a resin frame portion 72 arranged to surround the mounting surface 711, a front edge member 73 provided on the front edge of the internal shelf 70, and a fixing member 74 that fixes the front edge member 73.

前縁部材７３は、庫内棚７０の前縁部を覆い、庫内棚７０の剛性を高めたり、樹脂製の枠部７２を保護したりする機能を有する部材であり、庫内棚７０を補強する。このため前縁部材７３を補強部材と呼んで説明する場合がある。 The leading edge member 73 is a member that covers the leading edge of the internal shelf 70, and has the functions of increasing the rigidity of the internal shelf 70 and protecting the resin frame portion 72, thereby reinforcing the internal shelf 70. For this reason, the leading edge member 73 may be referred to as a reinforcing member.

図４は、図３のIV部の拡大斜視図である。
枠部７２は、略四角形（略矩形状）を成す載置面の前縁部、後縁部、左側縁部、および右側縁部を取り囲む本体部７２１と、本体部７２１の前縁部から前方に突出するように設けられた突出部７２２と、を有する。突出部７２２は本体部７２１を形成する樹脂材で本体部７２１と一体成形されている。 FIG. 4 is an enlarged perspective view of a portion IV in FIG.
The frame 72 has a main body 721 that surrounds the front edge, rear edge, left edge, and right edge of the mounting surface that has a substantially quadrangular (substantially rectangular) shape, and a protruding portion 722 that is provided so as to protrude forward from the front edge of the main body 721. The protruding portion 722 is molded integrally with the main body 721 using the resin material that forms the main body 721.

突出部（第１突出部）７２２は、冷蔵庫１の幅方向（左右方向）における一端部（本実施例では右端部）に設けられる。突出部７２２は、前縁部材７３が本体部７２１の前縁部に取り付けられた状態で、庫内棚７０の一端部で前縁部材７３の右方向への移動を規制し、前縁部材７３の左右方向における位置を固定する。このため突出部７２２は、規制部（第１規制部）または固定部（第１固定部）と呼ぶこともできる。突出部（第１固定部）７２２は、枠部７２と一体成形されていることで、枠部７２（庫内棚７０）に固定されている固定部である。 The protrusion (first protrusion) 722 is provided at one end (the right end in this embodiment) in the width direction (left-right direction) of the refrigerator 1. When the leading edge member 73 is attached to the leading edge portion of the main body portion 721, the protrusion 722 restricts the rightward movement of the leading edge member 73 at one end of the internal shelf 70 and fixes the position of the leading edge member 73 in the left-right direction. For this reason, the protrusion 722 can also be called a restricting portion (first restricting portion) or a fixing portion (first fixing portion). The protrusion (first fixing portion) 722 is a fixing portion that is fixed to the frame portion 72 (internal shelf 70) by being integrally molded with the frame portion 72.

突出部７２２は、前縁部材７３から右側方に露出する部分の左右方向寸法（厚み寸法）がｔ７２２の大きさに形成されている。 The protrusion 722 is formed so that the left-right dimension (thickness dimension) of the portion exposed to the right side from the front edge member 73 is t722.

図５は、図３のＶ部の拡大斜視図である。
固定部材７４は、庫内棚７０の他端部に取り付けられ、この他端部で前縁部材７３の左方向への移動を規制し、前縁部材７３の左右方向における位置を固定するための部材である。すなわち固定部材７４は、前縁部材７３の規制部（第２規制部）または固定部（第２固定部）を構成する部材である。固定部材７４は、枠部７２（庫内棚７０）に対して着脱可能に構成される固定部であることが好ましい。 FIG. 5 is an enlarged perspective view of a portion V in FIG.
The fixing member 74 is attached to the other end of the internal shelf 70, and is a member that restricts the movement of the leading edge member 73 to the left at this other end, and fixes the position of the leading edge member 73 in the left-right direction. In other words, the fixing member 74 is a member that constitutes a restricting portion (second restricting portion) or a fixing portion (second fixing portion) of the leading edge member 73. The fixing member 74 is preferably a fixing portion that is configured to be detachable from the frame portion 72 (internal shelf 70).

図６は、図３のＶ部を矢印VI方向から見た拡大斜視図である。
固定部材７４は、枠部７２の本体部７２１に締結される締結部７４１と、締結部７４１から前方に突出する突出部（第２突出部）７４２と、を有する。 FIG. 6 is an enlarged perspective view of portion V in FIG. 3 as viewed in the direction of arrow VI.
The fixing member 74 has a fastening portion 741 that is fastened to the main body portion 721 of the frame portion 72 , and a protrusion (second protrusion) 742 that protrudes forward from the fastening portion 741 .

締結部７４１は、ねじやリベット等の締結具７５で本体部７２１に対して締結される。この場合、締結部７４１は、ねじやその他の着脱を可能とする締結具７５により、本体部７２１に対して締結されることが好ましい。 The fastening portion 741 is fastened to the main body portion 721 by a fastener 75 such as a screw or a rivet. In this case, it is preferable that the fastening portion 741 is fastened to the main body portion 721 by a fastener 75 that allows attachment and detachment such as a screw or other fastener.

なお締結部７４１は、枠部７２の本体部７２１に固定される被固定部であり、被固定部と呼んで説明する場合もある。また第２突出部７４２は、前縁部材７３の一方の端部（左端部）に対向する対向部を構成するため、対向部と呼んで説明する場合もある。 The fastening portion 741 is a fixed portion that is fixed to the main body portion 721 of the frame portion 72, and may be referred to as the fixed portion. The second protruding portion 742 constitutes a facing portion that faces one end (left end) of the front edge member 73, and may be referred to as the facing portion.

第２突出部（対向部）７４２は、前縁部材７３の側縁部に当接する部位であり、前縁部材７３を介して第１突出部７２２と対向するように配置される。第２規制部または第２固定部は、第２突出部７４２によって構成される。 The second protruding portion (opposing portion) 742 is a portion that abuts against the side edge portion of the leading edge member 73, and is disposed so as to face the first protruding portion 722 via the leading edge member 73. The second restricting portion or the second fixing portion is constituted by the second protruding portion 742.

締結部７４１と第２突出部７４２とは、第２突出部７４２が締結部７４１に対して上方に位置するように、階段状に構成されている。すなわち、第２突出部７４２の上縁部は締結部７４１の上縁部に対して上方に位置する。締結部７４１と第２突出部７４２とが階段状に形成されていることで、締結部７４１は枠部７２の上端面７２ａの下側に配置され、上端面７２ａに露出しない。一方、締結部７４１は、その上縁部が枠部７２の上端面７２ａと同じ高さになるように配置され、上端面７２ａに露出している。 The fastening portion 741 and the second protruding portion 742 are configured in a stepped manner so that the second protruding portion 742 is located above the fastening portion 741. In other words, the upper edge of the second protruding portion 742 is located above the upper edge of the fastening portion 741. Because the fastening portion 741 and the second protruding portion 742 are formed in a stepped manner, the fastening portion 741 is located below the upper end surface 72a of the frame portion 72 and is not exposed at the upper end surface 72a. On the other hand, the fastening portion 741 is located so that its upper edge is at the same height as the upper end surface 72a of the frame portion 72 and is exposed at the upper end surface 72a.

締結部７４１は上下方向寸法（高さ寸法）がｈ７４１である。第２突出部７４２は上下方向寸法（高さ寸法）がｈ７４２である。締結部７４１の高さ寸法ｈ７４１は第２突出部７４２の高さ寸法ｈ７４２よりも大きい（ｈ７４１＞ｈ７４２）。 The fastening portion 741 has a vertical dimension (height dimension) of h741. The second protruding portion 742 has a vertical dimension (height dimension) of h742. The height dimension h741 of the fastening portion 741 is greater than the height dimension h742 of the second protruding portion 742 (h741>h742).

締結部７４１は締結具７５により枠部７２の本体部７２１に締結される部位であり、締結具７５を収納できる大きさが必要である。本実施例では、締結具７５としてねじを用いている。締結具７５がねじの場合、締結部７４１にはねじの頭部を収納できる大きさが必要である。また、ねじの頭部を締結部７４１から突出させることなく、締結部７４１の厚み寸法ｔ７４１の中に収納するために、締結部７４１には、その側面７４１ａに庫内棚７０の左右方向中央部側に向かって窪んだ凹部７４１ｂを設ける必要がある。 The fastening portion 741 is a portion that is fastened to the main body portion 721 of the frame portion 72 by the fastener 75, and must be large enough to accommodate the fastener 75. In this embodiment, a screw is used as the fastener 75. When the fastener 75 is a screw, the fastening portion 741 must be large enough to accommodate the head of the screw. Also, in order to accommodate the head of the screw within the thickness dimension t741 of the fastening portion 741 without protruding from the fastening portion 741, the fastening portion 741 must be provided with a recess 741b on its side surface 741a that is recessed toward the center of the interior shelf 70 in the left-right direction.

締結具７５としてねじを用いる場合、低頭ねじを用いることにより、凹部７４１ｂの深さを浅くすることができ、締結部７４１の厚み寸法ｔ７４１をより小さくすることができる。 When using a screw as the fastener 75, the depth of the recess 741b can be made shallower by using a low-head screw, and the thickness dimension t741 of the fastening portion 741 can be made smaller.

また、ｈ７４１＞ｈ７４２とすることにより、凹部７４１ｂの形成が可能になると共に、締結具７５の頭部を締結部７４１の高さ寸法ｈ７４１の範囲内に収納することが可能になる。なお、締結部７４１の高さ寸法ｈ７４１を少しでも小さくできるように、凹部７４１ｂは、その下端部で、凹部７４１ｂの側壁が切り欠かれ、開放部７４１ｃが形成された状態になっている。 In addition, by making h741>h742, it becomes possible to form recess 741b, and it becomes possible to store the head of fastener 75 within the range of height dimension h741 of fastening portion 741. In order to make height dimension h741 of fastening portion 741 as small as possible, the side wall of recess 741b is cut out at its lower end, and an open portion 741c is formed.

第２突出部７４２は、その高さ寸法ｈ７４２を、左右方向に隣接する前縁部材７３の厚み（上下方向の寸法）と揃えることで、意匠性（デザイン性）を向上することができる。ｈ７４１＞ｈ７４２とすることにより、第２突出部７４２の高さ寸法ｈ７４２を小さくすることができ、左右方向に隣接する前縁部材７３も、その上下方向の寸法（厚み寸法）を小さくすることができ、意匠性が向上する。 The design quality (designability) of the second protrusion 742 can be improved by aligning its height dimension h742 with the thickness (vertical dimension) of the leading edge member 73 adjacent to it in the left-right direction. By making h741 > h742, the height dimension h742 of the second protrusion 742 can be reduced, and the vertical dimension (thickness dimension) of the leading edge member 73 adjacent to it in the left-right direction can also be reduced, improving the design quality.

図７は、図３のＶ部の分解斜視図である。
枠部７２の本体部７２１の前縁部には、前縁部材７３が取り付けられる前縁部材取付部７２３が設けられている。前縁部材取付部７２３は本体部７２１を形成する樹脂材で本体部７２１と一体成形されている。固定部材７４が枠部７２に取り付けられた状態では、固定部材７４の締結部７４１が枠部７２の本体部７２１と対向する位置に配置され、固定部材７４の第２突出部７４２が前縁部材取付部７２３の側面と対向する位置に配置される。 FIG. 7 is an exploded perspective view of the V portion of FIG.
A front edge member attachment portion 723 to which the front edge member 73 is attached is provided on the front edge of the main body portion 721 of the frame portion 72. The front edge member attachment portion 723 is molded integrally with the main body portion 721 using the resin material that forms the main body portion 721. When the fixing member 74 is attached to the frame portion 72, the fastening portion 741 of the fixing member 74 is disposed at a position facing the main body portion 721 of the frame portion 72, and the second protrusion 742 of the fixing member 74 is disposed at a position facing the side surface of the front edge member attachment portion 723.

固定部材７４の締結部７４１は、締結具７５が挿通する挿通孔７４１ａを有する。 The fastening portion 741 of the fixing member 74 has an insertion hole 741a through which the fastener 75 is inserted.

固定部材７４の第２突出部７４２は、前縁部材７３の内面に挿入して嵌められる嵌挿部７４３と、前縁部材７３に掛け止める掛止部（フック部）７４４と、を有する。掛止部（フック部）７４４は嵌挿部７４３よりも前縁部材７３のさらに奥部まで挿入される長さを有する。すなわち、固定部材７４の第２突出部（対向部）７４２は、前縁部材７３の内側に挿入され、前縁部材７３に掛け止められる掛止部を有する。 The second protrusion 742 of the fixing member 74 has a fitting portion 743 that is inserted and fitted into the inner surface of the leading edge member 73, and a hook portion (hook portion) 744 that hooks onto the leading edge member 73. The hook portion (hook portion) 744 has a length that allows it to be inserted further into the leading edge member 73 than the fitting portion 743. In other words, the second protrusion (facing portion) 742 of the fixing member 74 has a hook portion that is inserted into the inside of the leading edge member 73 and hooked onto the leading edge member 73.

図８は、本発明に係る庫内棚７０の枠部７２３と前縁部材７３とを示す概略図である。
前縁部材７３は、左右方向に垂直な断面形状が後側から前側に向かって窪んだ凹形状を成し、凹形状の内側に空間７３２が形成されている。また前縁部材７３は、左右方向に垂直な断面形状が後方に向かって開口する開口７３３を有する。そして前縁部材７３は、凹形状内側の空間７３２に前縁部材取付部７２３が挿入されるようにして、庫内棚７０の前縁に取り付けられる。 FIG. 8 is a schematic diagram showing a frame portion 723 and a front edge member 73 of an internal shelf 70 according to the present invention.
The leading edge member 73 has a cross-sectional shape perpendicular to the left-right direction that is recessed from the rear side to the front side, and a space 732 is formed inside the concave shape. The leading edge member 73 also has an opening 733 whose cross-sectional shape perpendicular to the left-right direction opens toward the rear. The leading edge member 73 is attached to the leading edge of the internal shelf 70 such that the leading edge member attachment portion 723 is inserted into the space 732 inside the concave shape.

前縁部材７３は、上面７３ａと、上面７３ａの前縁部に沿って形成された前端面７３ｂと、前端面７３ｂの下端縁に沿って形成された第１下面７３ｃ１と、第１下面７３ｃ１に対して段付き状に形成された第２下面７３ｃ２と、第１下面７３ｃ１と第２下面７３ｃ２とを接続する段差面７３ｃ３と、上面７３ａの後縁部に沿って形成された下垂部７３ｄと、第２下面７３ｃ２の後縁部に沿って形成された傾斜部７３ｅと、を有する。 The front edge member 73 has an upper surface 73a, a front end surface 73b formed along the front edge of the upper surface 73a, a first lower surface 73c1 formed along the lower edge of the front end surface 73b, a second lower surface 73c2 formed in a stepped shape relative to the first lower surface 73c1, a step surface 73c3 connecting the first lower surface 73c1 and the second lower surface 73c2, a drooping portion 73d formed along the rear edge of the upper surface 73a, and an inclined portion 73e formed along the rear edge of the second lower surface 73c2.

上面７３ａは、庫内棚７０の載置面７１１と平行な面で構成される。前端面７３ｂは、上面７３ａの前縁部から下方に向かって折り曲げられて形成される。第１下面７３ｃ１は、前端面７３ｂの下端部から水平方向に折り曲げられて形成される。第２下面７３ｃ２は、第１下面７３ｃ１に対して後方に位置するように段付き状に折り曲げられて形成される。その結果、第１下面７３ｃ１と第２下面７３ｃ２との間には段差面７３ｃ３が形成され、段差面７３ｃ３は、第１下面７３ｃ１の後縁部と第２下面７３ｃ２の前縁部とを接続するように、後方に向かって上昇する傾斜面を構成する。下垂部７３ｄは、上面７３ａの後縁部から垂直に折り曲げられて下垂するように形成される。傾斜部７３ｅは、第２下面７３ｃ２の後縁部から、後方に向かって下降する傾斜面として形成される。本実施例では、上面７３ａと前端面７３ｂとの間の角度、および第１下面７３ｃ１と前端面７３ｂとの間の角度は９０°、すなわち垂直に形成される。なお、前端面７３ｂは平面としているが、曲面であってもよい。 The upper surface 73a is formed as a surface parallel to the placement surface 711 of the internal shelf 70. The front end surface 73b is formed by bending downward from the front edge of the upper surface 73a. The first lower surface 73c1 is formed by bending horizontally from the lower end of the front end surface 73b. The second lower surface 73c2 is formed by bending in a stepped shape so as to be located rearward relative to the first lower surface 73c1. As a result, a step surface 73c3 is formed between the first lower surface 73c1 and the second lower surface 73c2, and the step surface 73c3 constitutes an inclined surface that rises toward the rear so as to connect the rear edge of the first lower surface 73c1 and the front edge of the second lower surface 73c2. The drooping portion 73d is formed so as to droop downward by being bent vertically from the rear edge of the upper surface 73a. The inclined portion 73e is formed as an inclined surface that descends rearward from the rear edge of the second lower surface 73c2. In this embodiment, the angle between the upper surface 73a and the front end surface 73b, and the angle between the first lower surface 73c1 and the front end surface 73b are 90°, i.e., vertical. Note that the front end surface 73b is a flat surface, but it may also be a curved surface.

前縁部材７３は、金属製の平板を曲げ加工して形成される。金属製の平板は、加工性を良くし、コストを低減するため、肉厚の小さい平板を用いることが好ましい。しかし肉厚の小さい平板を用いた場合、前縁部材７３の剛性が小さくなる。本実施例では、特に第１下面７３ｃ１および第２下面７３ｃ２を加工するなどして曲げ加工を増やしているため、前縁部材７３の剛性を大きくすることができる。これにより、庫内棚７０を前縁部材７３で補強して、庫内棚７０の剛性を大きくすることができ、庫内棚７０の撓みを抑制することができる。 The leading edge member 73 is formed by bending a metal flat plate. It is preferable to use a thin metal flat plate to improve workability and reduce costs. However, if a thin flat plate is used, the rigidity of the leading edge member 73 will be reduced. In this embodiment, the amount of bending is increased, particularly by processing the first lower surface 73c1 and the second lower surface 73c2, so the rigidity of the leading edge member 73 can be increased. This allows the internal shelf 70 to be reinforced with the leading edge member 73, increasing the rigidity of the internal shelf 70 and suppressing deflection of the internal shelf 70.

枠部７２の前縁部材取付部７２３は、上面７２３ａと、上面７３ａの前縁部に沿って形成された前端面７２３ｂと、前端面７３ｂの下端縁に沿って形成された第１下面７２３ｃ１と、上面７２３ａの後縁部に沿って形成された溝部７２３ｄと、第１下面７２３ｃ１から離間した後方に形成された傾斜部７２３ｅと、を有し、第１下面７２３ｃ１と傾斜面７２３ｅとの間には空洞７２３ｆを形成する凹面７２３ｇが形成されている。 The front edge member attachment portion 723 of the frame portion 72 has an upper surface 723a, a front end surface 723b formed along the front edge of the upper surface 73a, a first lower surface 723c1 formed along the lower edge of the front end surface 73b, a groove portion 723d formed along the rear edge of the upper surface 723a, and an inclined portion 723e formed rearward away from the first lower surface 723c1, and a concave surface 723g that forms a cavity 723f is formed between the first lower surface 723c1 and the inclined surface 723e.

上面７２３ａは、庫内棚７０の載置面７１１と平行な面で構成される。前端面７２３ｂは、上面７２３ａに対して前側において、上面７３ａと第１下面７２３ｃ１との間に設けられる。第１下面７２３ｃ１は、前端面７３ｂに対して下方かつ後方に設けられる。溝部７２３ｄは、上面７２３ａに対して後方に設けられる。傾斜部７２３ｅは、後方に向かって下降する傾斜面として形成される。 The upper surface 723a is configured as a surface parallel to the placement surface 711 of the internal shelf 70. The front end surface 723b is provided in front of the upper surface 723a, between the upper surface 73a and the first lower surface 723c1. The first lower surface 723c1 is provided below and rearward of the front end surface 73b. The groove portion 723d is provided rearward of the upper surface 723a. The inclined portion 723e is formed as an inclined surface that slopes downward toward the rear.

前縁部材７３は、前縁部材取付部７２３の左端、固定部材７４が設けられる側の端部から、前縁部材取付部７２３にスライドさせるようにして取り付けられる。このとき、前縁部材７３は、下垂部７３ｄを前縁部材取付部７２３の溝部７２３ｄに挿入した状態で、上面７３ａ、前端面７３ｂ、第１下面７３ｃ１、および傾斜部７３ｅのそれぞれを、前縁部材取付部７２３の上面７２３ａ、前端面７２３ｂ、第１下面７２３ｃ１、および傾斜部７２３ｅのそれぞれに摺動させながら、左方向（第１固定部（第１突出部）７２２に向かう方向）に移動させて、前縁部材取付部７２３に組み付けられる。 The leading edge member 73 is attached by sliding it from the left end of the leading edge member attachment portion 723, the end on the side where the fixing member 74 is provided, to the leading edge member attachment portion 723. At this time, with the hanging portion 73d inserted into the groove portion 723d of the leading edge member attachment portion 723, the leading edge member 73 is assembled to the leading edge member attachment portion 723 by moving it leftward (toward the first fixing portion (first protruding portion) 722) while sliding the upper surface 73a, the front end surface 73b, the first lower surface 723c1, and the inclined portion 73e of the leading edge member attachment portion 723, respectively.

前縁部材７３が前縁部材取付部７２３に組み付けられた状態では、前縁部材７３の下垂部７３ｄが前縁部材取付部７２３の溝部７２３ｄに挿入された状態で、上面７３ａ、前端面７３ｂ、第１下面７３ｃ１、および傾斜部７３ｅのそれぞれが、前縁部材取付部７２３の上面７２３ａ、前端面７２３ｂ、第１下面７２３ｃ１、および傾斜部７２３ｅのそれぞれに当接した状態を維持することで、前縁部材７３の前後方向の移動およびガタツキが抑制される。 When the leading edge member 73 is attached to the leading edge member attachment portion 723, the hanging portion 73d of the leading edge member 73 is inserted into the groove portion 723d of the leading edge member attachment portion 723, and the upper surface 73a, the front end surface 73b, the first lower surface 73c1, and the inclined portion 73e are each maintained in contact with the upper surface 723a, the front end surface 723b, the first lower surface 723c1, and the inclined portion 723e of the leading edge member attachment portion 723, respectively, thereby suppressing forward/rearward movement and rattling of the leading edge member 73.

なお、前縁部材７３の上面７３ａ、前端面７３ｂ、第１下面７３ｃ１、および傾斜部７３ｅのそれぞれと、前縁部材取付部７２３の上面７２３ａ、前端面７２３ｂ、第１下面７２３ｃ１、および傾斜部７２３ｅのそれぞれとが当接した状態は、これらの全ての面で当接している必要はなく、前縁部材７３のガタツキを抑制するのに必要な複数の面が当接していればよい。 The upper surface 73a, front end surface 73b, first lower surface 73c1, and inclined portion 73e of the leading edge member 73 do not need to be in contact with the upper surface 723a, front end surface 723b, first lower surface 723c1, and inclined portion 723e of the leading edge member attachment portion 723 on all of these surfaces, but rather it is sufficient that a number of surfaces necessary to suppress rattling of the leading edge member 73 are in contact.

また、前縁部材７３の上面７３ａ、前端面７３ｂ、および第１下面７３ｃ１のそれぞれと、前縁部材取付部７２３の上面７２３ａ、前端面７２３ｂ、および第１下面７２３ｃ１のそれぞれとは、平面部で構成されるか、少なくとも一部に平面部を有していて、これらの平面部において前縁部材７３と前縁部材取付部７２３とを当接させることにより、前縁部材７３と前縁部材取付部７２３との当接を容易に得ることができる。 In addition, the upper surface 73a, front end surface 73b, and first lower surface 73c1 of the leading edge member 73 and the upper surface 723a, front end surface 723b, and first lower surface 723c1 of the leading edge member attachment portion 723 are each composed of a flat surface portion or have a flat surface portion at least in part, and the leading edge member 73 and the leading edge member attachment portion 723 can be easily brought into contact with each other by abutting them at these flat surfaces.

また、固定部材７４の締結部７４１が枠部７２に取り付けられることで、前縁部材７３は、左右両側から固定部材（第２固定部）７４および第１固定部（第１突出部）７２２により挟持され、前縁部材取付部７２３に固定される。第２固定部７４および第１固定部７２２は、前縁部材７３の左右方向の移動およびガタツキを抑制する。この場合、第２固定部７４はねじ７５による締結力と、第２固定部７４を形成する樹脂の剛性とにより、前縁部材７３の左右方向の移動およびガタツキを抑制する。 In addition, by attaching the fastening portion 741 of the fixing member 74 to the frame portion 72, the leading edge member 73 is clamped from both the left and right sides by the fixing member (second fixing portion) 74 and the first fixing portion (first protruding portion) 722 and fixed to the leading edge member attachment portion 723. The second fixing portion 74 and the first fixing portion 722 suppress left-right movement and wobbling of the leading edge member 73. In this case, the second fixing portion 74 suppresses left-right movement and wobbling of the leading edge member 73 by the fastening force of the screw 75 and the rigidity of the resin that forms the second fixing portion 74.

図９は、図３のＶ部を斜め下から見た斜視図であり、固定部材を取り除いた状態の斜視図である。
枠部７２の本体部７２１の側面７２１ａには反対側の側面に向かって窪んだ凹部７２４が形成されており、凹部７２４の底面に締結具を挿入する締結具挿入孔（本実施例の場合、ねじ７５を螺合するねじ穴）７２４ａが形成されている。この凹部７２４に固定部材７４の締結部７４１が挿入されることで、締結部７４１は側面７２１ａから飛び出すことなく、凹部７２４の内部に収納される。これにより、上方から庫内棚７０を見た場合に、締結部７４１は枠部７２の本体部７２１の陰に隠れて本体部７２１からの露出が防止される（図１０および図１１参照）。このとき締結具７５は、締結部７４１の凹部７４１ｂに収納されており、上方から庫内棚７０を見た場合に、本体部７２１から露出することはない（図１０および図１１参照）。 9 is a perspective view of the V portion in FIG. 3 as viewed obliquely from below, with the fixing member removed.
A recess 724 recessed toward the opposite side surface is formed in the side surface 721a of the main body 721 of the frame 72, and a fastener insertion hole (a screw hole into which the screw 75 is screwed in the case of this embodiment) 724a into which a fastener is inserted is formed in the bottom surface of the recess 724. When the fastening portion 741 of the fixing member 74 is inserted into this recess 724, the fastening portion 741 is stored inside the recess 724 without protruding from the side surface 721a. As a result, when the internal shelf 70 is viewed from above, the fastening portion 741 is hidden behind the main body 721 of the frame 72 and is prevented from being exposed from the main body 721 (see Figures 10 and 11). At this time, the fastening device 75 is stored in the recess 741b of the fastening portion 741, and is not exposed from the main body 721 when the internal shelf 70 is viewed from above (see Figures 10 and 11).

前縁部材７３の第２下面７３ｃ２には、上下方向に貫通する貫通穴７３１が形成されている。貫通穴７３１は、左右方向において、庫内棚７０の中央部よりも固定部材（第２固定部）７４側の側縁部の近くに設けられる。 A through hole 731 that penetrates in the up-down direction is formed in the second lower surface 73c2 of the front edge member 73. The through hole 731 is provided closer to the side edge of the fixed member (second fixed portion) 74 side than to the center of the internal shelf 70 in the left-right direction.

図１０は、固定部材７４の近傍を一部断面（図１１のＸ－Ｘ断面）で示す斜視図である。図１１は、図３のＶ部を下方から見た平面図である。図１２は、図１１のXII－XII断面図である。 Figure 10 is a perspective view showing a partial cross section (cross section X-X in Figure 11) of the vicinity of the fixing member 74. Figure 11 is a plan view of part V in Figure 3 as seen from below. Figure 12 is a cross section XII-XII in Figure 11.

固定部材７４に設けられた掛止部（フック部）７４４は、前縁部材取付部７２３の凹面７２３ｇによって形成される空洞７２３ｆに挿入される。掛止部（フック部）７４４は、下方に向かって突状を成す突形状部７４４ａが設けられており、この突形状部７４４ａが前縁部材７３の貫通穴７３１に嵌入される。固定部材７４に対して第２突出部７４２が前縁部材７３から離れる方向に力がかかった場合に、固定部材７４が前縁部材７３から離れるのを防止して、前縁部材７３の前縁部材取付部７２３からの抜けを防止する。 The hook portion 744 provided on the fixed member 74 is inserted into a cavity 723f formed by the concave surface 723g of the front edge member attachment portion 723. The hook portion 744 is provided with a protruding portion 744a that protrudes downward, and this protruding portion 744a is fitted into the through hole 731 of the front edge member 73. When a force is applied to the fixed member 74 in a direction in which the second protrusion 742 moves away from the front edge member 73, the hook portion 744 is prevented from moving away from the front edge member 73, and the front edge member 73 is prevented from coming off the front edge member attachment portion 723.

本実施例では、前縁部材７３は前縁部材取付部７２３と複数の面で当接して、前縁部材取付部７２３に対して、ある程度の固定力が得られる。もし、前縁部材取付部７２３に対する前縁部材７３の固定力が不足する場合は、前縁部材７３を締結具７６で前縁部材取付部７２３に固定するとよい。この締結具７６は前縁部材７３の下面７３ｃ１，７３ｃ２側に配される。締結具７６の頭部は第２下面７３ｃ２上に位置する。第２下面７３ｃ２は第１下面７３ｃ１よりも高い位置にあり、第２下面７３ｃ２と第１下面７３ｃ１との間に段差が形成されている。このため、前方から見た場合に、締結具７６の頭部は前縁部材７３の陰に隠れて見えなくなり、意匠性が向上する。 In this embodiment, the front edge member 73 abuts against the front edge member attachment portion 723 on multiple surfaces, and a certain degree of fixing force is obtained against the front edge member attachment portion 723. If the fixing force of the front edge member 73 against the front edge member attachment portion 723 is insufficient, the front edge member 73 may be fixed to the front edge member attachment portion 723 with a fastener 76. This fastener 76 is arranged on the lower surface 73c1, 73c2 side of the front edge member 73. The head of the fastener 76 is located on the second lower surface 73c2. The second lower surface 73c2 is located higher than the first lower surface 73c1, and a step is formed between the second lower surface 73c2 and the first lower surface 73c1. Therefore, when viewed from the front, the head of the fastener 76 is hidden behind the front edge member 73 and cannot be seen, improving the design.

固定部材７４は、前縁部材７３から左側方に露出する部分（すなわち第２突出部）７４２の左右方向寸法（厚み寸法）がｔ７４２の大きさに形成されている。固定部材７４の第２突出部７４２における厚み寸法ｔ７４２と第１突出部７２２における厚み寸法ｔ７２２とは同じ大きさである（ｔ７４２＝ｔ７２２）。これにより、庫内棚７０を左右対称に構成することができ、庫内棚７０の意匠性を良好にすることができる。 The fixing member 74 is formed so that the left-right dimension (thickness dimension) of the portion (i.e., the second protruding portion) 742 exposed to the left side from the front edge member 73 is t742. The thickness dimension t742 of the second protruding portion 742 of the fixing member 74 is the same as the thickness dimension t722 of the first protruding portion 722 (t742 = t722). This allows the internal shelf 70 to be configured symmetrically, improving the design of the internal shelf 70.

第１突出部７２２は枠部７２の本体部７２１と一体成形されており、枠部７２に締結する締結部を設ける必要がなく、厚み寸法ｔ７２２を小さくすることは容易である。一方、固定部材７４は枠部７２に締結する締結部を設ける必要があり、固定部材７４の厚み寸法を小さくすることは容易ではない。 The first protrusion 722 is integrally molded with the main body 721 of the frame 72, and there is no need to provide a fastening portion for fastening to the frame 72, so it is easy to reduce the thickness dimension t722. On the other hand, the fixing member 74 needs to have a fastening portion for fastening to the frame 72, and it is not easy to reduce the thickness dimension of the fixing member 74.

本実施例では、図１０に示すように、固定部材７４を締結部７４１と第２突出部７４２とに分け、第２突出部７４２の厚み寸法ｔ７４２を締結部７４１の厚み寸法ｔ７４１よりも小さくする（ｔ７４２＜ｔ７４１）。これにより、第２突出部７４２の厚み寸法ｔ７４２を第１突出部７２２の厚み寸法ｔ７２２と同等に小さくすることができる。第１突出部７２２の厚み寸法ｔ７２２および第２突出部７４２の厚み寸法ｔ７４２を小さくすることができることで、庫内棚７０の外観を美しく仕上げることができ、意匠性に優れた庫内棚７０を提供することができる。 In this embodiment, as shown in FIG. 10, the fixing member 74 is divided into a fastening portion 741 and a second protruding portion 742, and the thickness dimension t742 of the second protruding portion 742 is made smaller than the thickness dimension t741 of the fastening portion 741 (t742<t741). This allows the thickness dimension t742 of the second protruding portion 742 to be as small as the thickness dimension t722 of the first protruding portion 722. By making the thickness dimension t722 of the first protruding portion 722 and the thickness dimension t742 of the second protruding portion 742 small, the exterior of the internal shelf 70 can be beautifully finished, and an internal shelf 70 with excellent design can be provided.

また、本実施例では、締結具７５としてねじを用いているが、締結時に工具を必要としないブッシュや固定部材７４に一体成型で設けた爪部（図示無し）であってもよい。これにより、樹脂製の枠部７２と金属製の前縁部材７３とを分別して解体する作業工程が簡略できる。 In addition, in this embodiment, screws are used as the fasteners 75, but they may be bushes that do not require tools for fastening, or claws (not shown) that are integrally molded into the fixing member 74. This simplifies the work process of separating and dismantling the resin frame 72 and the metal front edge member 73.

図１３は、図３のＶ部を載置面７１１の部分で載置面７１１に平行に切断した拡大断面図である。
枠部７２の本体部７２１には、締結具７５を挿入する締結具挿入孔７２４ａが形成されている。この締結具挿入孔７２４ａは、載置面７１１を構成する載置面部材７１の外縁７１ｂの角部と干渉し易い位置にある。本実施例では、締結具挿入孔７２４ａに挿入される締結具７５と載置面部材７１との干渉を避けるため、載置面部材７１の外縁７１ｂの角部に切欠き部７１ｃを設けている。 FIG. 13 is an enlarged cross-sectional view of the V portion of FIG. 3 cut parallel to the mounting surface 711 at the mounting surface 711. As shown in FIG.
A fastener insertion hole 724a for inserting a fastener 75 is formed in the main body 721 of the frame 72. This fastener insertion hole 724a is located in a position that is likely to interfere with a corner of the outer edge 71b of the mounting surface member 71 that constitutes the mounting surface 711. In this embodiment, in order to prevent interference between the fastener 75 inserted into the fastener insertion hole 724a and the mounting surface member 71, a notch 71c is provided in the corner of the outer edge 71b of the mounting surface member 71.

次に、図１４および図１５を参照して、庫内棚７０の支持構造について説明する。図１４は、図２の内箱８を左右中央部で切断した断面図である。図１５は、図１４のXV部の拡大斜視図である。 Next, the support structure of the internal shelf 70 will be described with reference to Figures 14 and 15. Figure 14 is a cross-sectional view of the inner box 8 in Figure 2 cut at the center on the left and right. Figure 15 is an enlarged perspective view of part XV in Figure 14.

冷蔵室２内の庫内棚７０は、内箱８の左右方向の両側面に形成された棚リブ１３に支持される。このため庫内棚７０は、特に左右方向中央部が下がるような撓みを生じ易い。 The internal shelf 70 in the refrigerator compartment 2 is supported by shelf ribs 13 formed on both left and right sides of the inner box 8. For this reason, the internal shelf 70 is prone to bending, particularly in the center part in the left and right direction.

そこで本実施例では、内箱８の背面側に、庫内棚７０の後縁部を支持する支持部１６を設ける。本実施例では、冷気を送風する送風ダクト１５部に支持部１６を設けている。より具体的には、支持部１６は送風ダクトを覆う部材１７に設けられている。支持部１６は、送風ダクト１５における、冷蔵室２内に面する面から、前方に突出するように、設けられている。この場合、支持部１６は送風ダクト１５を覆う化粧部材１７によって構成することで、部品点数や製造工程における工程数を低減することができる。 In this embodiment, therefore, a support portion 16 that supports the rear edge of the internal shelf 70 is provided on the rear side of the inner box 8. In this embodiment, the support portion 16 is provided on the air duct 15 that blows cold air. More specifically, the support portion 16 is provided on a member 17 that covers the air duct.
