A corner portion on the left end side of the box portion 22 of the inner box 14 is chamfered to form a so-called C surface.

第１部分３１は、全体的に平面状に設けられており、その一部に支持溝２２Ｌを備えている。支持溝２２Ｌは、支持部の一例であり、第１部分３１の上下方向の一端部、この場合、上端部と上下方向の他端部、この場合、下端部との間において、左側から右側に向かって下降傾斜するように直線状に延びている。また、支持溝２２Ｌの上端部および下端部には、それぞれ拡大部２２Ｌａ，２２Ｌｂが設けられている。 The first portion 31 is provided in a flat shape as a whole and has a support groove 22L in a part thereof. The support groove 22L is an example of a support portion, and extends from the left side to the right side between one end portion in the vertical direction of the first portion 31, which is the upper end portion in this case, and the other end portion in the vertical direction, which is the lower end portion in this case. It extends linearly so as to slope downward. Enlarged portions 22La and 22Lb are provided at the upper and lower ends of the support groove 22L, respectively.

拡大部２２Ｌａは、全体として束線１７Ｌの径寸法よりも大きい幅寸法を有しており、且つ、下方から上方に向かって徐々に幅寸法が大きくなるように広がった形状をなしている。拡大部２２Ｌｂは、全体として束線１７Ｌの径寸法よりも大きい幅寸法を有しており、且つ、上方から下方に向かって徐々に幅寸法が大きくなるように広がった形状をなしている。また、拡大部２２Ｌａ，２２Ｌｂは、支持溝２２Ｌにおける他の部位、この場合、拡大部２２Ｌａと拡大部２２Ｌｂとの間における直線状の部位の幅寸法よりも大きい幅寸法を有する。即ち、支持溝２２Ｌは、その両端部の拡大部２２Ｌａ，２２Ｌｂに挟まれる中央部の幅寸法が束線１７Ｌの径寸法よりも大きく、その中央部よりもさらに拡大部２２Ｌａ，２２Ｌｂの幅寸法が大きい構成となっている。熱絶縁部材２１Ｌは、第１部分３１において支持溝２２Ｌに隣接する部分に平坦部３３を有している。熱絶縁部材２１Ｌは、支持溝２２Ｌ以外の部分である平坦部３３の面積が支持溝２２Ｌの面積よりも大きくなった構成となっている。 The enlarged portion 22La has a width dimension larger than the diameter dimension of the wire bundle 17L as a whole, and has a shape that widens so that the width dimension gradually increases from the bottom to the top. The enlarged portion 22Lb has a width dimension larger than the diameter dimension of the wire bundle 17L as a whole, and has a shape that widens so that the width dimension gradually increases from the top to the bottom. Further, the enlarged portions 22La and 22Lb have a width dimension larger than that of other portions in the support groove 22L, in this case, a linear portion between the enlarged portions 22La and 22Lb. That is, the support groove 22L has a width dimension at the central portion sandwiched between the enlarged portions 22La and 22Lb at both ends thereof, which is larger than the diameter dimension of the wire bundle 17L, and the enlarged portions 22La and 22Lb have a width dimension larger than that at the central portion. It has a large configuration. The heat insulating member 21L has a flat portion 33 in the first portion 31 adjacent to the support groove 22L. The heat insulating member 21L is configured such that the area of the flat portion 33, which is the portion other than the support groove 22L, is larger than the area of the support groove 22L.

また、熱絶縁部材２１Ｌは、第１部分３１の平坦部３３に複数の貫通孔３４，３５を備えている。このうち、貫通孔３４は、ほぼ円形状に開口しており、第１部分３１の上下方向の両端部寄り、つまり、上端部寄りの部分および下端部寄りの部分にそれぞれ設けられている。この場合、第１部分３１の上端部寄りには３つの貫通孔３４、第１部分３１の下端部寄りには２つの貫通孔３４が設けられており、つまり、第１部分３１の上端部側と下端部側とで貫通孔３４の数が異なる構成となっている。また、第１部分３１の上端部側に設けられている貫通孔３４と第１部分３１の下端部側に設けられている貫通孔３４とが支持溝２２Ｌによって分断された構成となっている。 The heat insulating member 21L also has a plurality of through holes 34 and 35 in the flat portion 33 of the first portion 31. As shown in FIG. Among them, the through-holes 34 are open in a substantially circular shape, and are provided near both ends in the vertical direction of the first portion 31, that is, near the upper end and near the lower end. In this case, three through-holes 34 are provided near the upper end of the first portion 31, and two through-holes 34 are provided near the lower end of the first portion 31, that is, the upper end of the first portion 31. The number of through-holes 34 differs between the bottom end side and the bottom end side. Further, the through hole 34 provided on the upper end side of the first portion 31 and the through hole 34 provided on the lower end side of the first portion 31 are divided by the support groove 22L.

一方、貫通孔３５は、上下方向に長い長尺なほぼ楕円形状に開口しており、第１部分３１の上下方向のほぼ中央部に設けられている。また、貫通孔３５は、この場合、２つ設けられており、一方の貫通孔３５は上下方向に沿って設けられており、他方の貫通孔３５は支持溝２２Ｌに沿うようにして傾斜して設けられている。また、２つの貫通孔３５は、支持溝２２Ｌによって分断された構成となっている。以上の通り、熱絶縁部材２１Ｌは、支持溝２２Ｌを挟む２つの領域に貫通孔３４，３５が分散して配置された構成となっている。 On the other hand, the through hole 35 has an elongated, substantially elliptical shape that is elongated in the vertical direction, and is provided substantially in the center of the first portion 31 in the vertical direction. In this case, two through holes 35 are provided. One through hole 35 is provided along the vertical direction, and the other through hole 35 is inclined along the support groove 22L. is provided. Also, the two through holes 35 are divided by the support groove 22L. As described above, the heat insulating member 21L has a configuration in which the through holes 34 and 35 are dispersedly arranged in two regions sandwiching the support groove 22L.

また、第１部分３１の内面側、つまり、内箱１４のボックス部２２に取り付けられた状態で当該ボックス部２２の後面に対向する面には、上下方向位置決め部３６および左右方向位置決め部３７が設けられている。上下方向位置決め部３６は、第１部分３１の上下方向のほぼ中央部において左右方向に延びる段差を形成する段部により構成されている。上下方向位置決め部３６の段差部分には、貫通孔３５が跨るようにして設けられている。一方、図２に例示するように、内箱１４のボックス部２２の後面には、後方に向かって突出し、且つ、左右方向に延びる突条部２２ａが設けられている。上下方向位置決め部３６は、内箱１４の突条部２２ａの上端面に上方から係合し、これにより、第１部分３１、ひいては、熱絶縁部材２１Ｌ全体の上下方向における位置決めを行う。 Further, on the inner surface side of the first portion 31, that is, on the surface facing the rear surface of the box portion 22 of the inner box 14 attached to the box portion 22, a vertical positioning portion 36 and a horizontal positioning portion 37 are provided. is provided. The vertical positioning portion 36 is formed of a stepped portion that forms a stepped portion extending in the horizontal direction at a substantially central portion in the vertical direction of the first portion 31 . A stepped portion of the vertical positioning portion 36 is provided with a through hole 35 extending therethrough. On the other hand, as exemplified in FIG. 2, the rear surface of the box portion 22 of the inner casing 14 is provided with a ridge portion 22a that protrudes rearward and extends in the left-right direction. The vertical positioning portion 36 engages with the upper end surface of the ridge portion 22a of the inner case 14 from above, thereby positioning the first portion 31 and, by extension, the entire heat insulating member 21L in the vertical direction.

左右方向位置決め部３７は、上下方向に延びる複数、この場合、２つの突条部３７ｂを有する凹凸部３７ａにより構成されている。突条部３７ｂは、上下方向位置決め部３６を形成する段差の壁面から離間し、且つ、当該壁面に対向するようにして設けられている。また、２つの突条部３７ｂの一方、この場合、第２部分３２とは反対側の突条部３７ｂは、第１部分３１において支持溝２２Ｌが設けられている部分の反対側に位置している。一方、図２に例示するように、内箱１４のボックス部２２の後面には、上下方向に延びる複数の溝２２ｄを有する凹凸部２２ｃが設けられている。熱絶縁部材２１Ｌは、内箱１４の凹凸部２２ｃに左右方向位置決め部３７の凹凸部３７ａを係合させた状態で内箱１４のボックス部２２の後面に取り付けられる。これにより、左右方向位置決め部３７は、第１部分３１、ひいては、熱絶縁部材２１Ｌ全体の左右方向における位置決めを行う。 The left-right direction positioning portion 37 is configured by an uneven portion 37a having a plurality of, in this case, two projecting portions 37b extending in the vertical direction. The ridge portion 37b is provided so as to be separated from the wall surface of the step forming the vertical positioning portion 36 and to face the wall surface. One of the two protrusions 37b, in this case, the protrusion 37b on the side opposite to the second portion 32, is located on the opposite side of the portion of the first portion 31 where the support groove 22L is provided. there is On the other hand, as illustrated in FIG. 2, the rear surface of the box portion 22 of the inner casing 14 is provided with an uneven portion 22c having a plurality of vertically extending grooves 22d. The heat insulating member 21L is attached to the rear surface of the box portion 22 of the inner case 14 in a state in which the uneven portions 22c of the inner case 14 are engaged with the uneven portions 37a of the horizontal positioning portion 37. As shown in FIG. Thereby, the left-right direction positioning part 37 positions the first portion 31 and, by extension, the heat insulating member 21L as a whole in the left-right direction.

また、図６に例示するように、内箱１４の凹凸部２２ｃに熱絶縁部材２１Ｌの凹凸部３７ａが係合した状態において、内箱１４の凹凸部２２ｃと熱絶縁部材２１Ｌの凹凸部３７ａとが対向する部分の少なくとも一部には、発泡ウレタンが流通可能な隙間Ｇが形成されるようになっている。また、この隙間Ｇは、第１部分３１に設けられている貫通孔３４，３５の少なくとも何れか１つ、この場合、第１部分３１の下端部に設けられている貫通孔３４に対向するようになっている。 Further, as illustrated in FIG. 6, in a state in which the uneven portion 37a of the heat insulating member 21L is engaged with the uneven portion 22c of the inner box 14, the uneven portion 22c of the inner case 14 and the uneven portion 37a of the heat insulating member 21L are aligned. In at least a part of the portion where the . Further, the gap G is arranged so as to face at least one of the through holes 34 and 35 provided in the first portion 31, in this case, the through hole 34 provided in the lower end portion of the first portion 31. It has become.

また、上述した通り、この場合、貫通孔３５が上下方向位置決め部３６の段差を跨ぐようにして設けられているため、当該貫通孔３５から流入する発泡ウレタンが上下方向位置決め部３６の段差を構成する壁面に沿って流れやすくなる。さらに、左右方向位置決め部３７の突条部３７ｂが上下方向位置決め部３６の段差を構成する壁面から離間し、且つ、当該壁面に対向するようにして設けられているので、貫通孔３５から当該壁面に沿って流れる発泡ウレタンが左右方向位置決め部３７側にも流れやすくなる。このように発泡ウレタンを流しやすくできる構成は、熱絶縁部材に限らず、冷蔵庫１０に備えられる他の特別部材にも適用することができる。特別部材としては、例えば、内箱１４の裏面とは異なる部位を覆う覆い部材、束線１７Ｌ，１７Ｒ以外の部材を支持する支持部材、内箱１４の裏面と束線１７Ｌ，１７Ｒとの間以外の部分を熱絶縁する熱絶縁部材、冷蔵庫１０の電気的構成部分を電気的に絶縁する電気絶縁部材など、冷蔵庫１０に備えられる種々の部材が考えられる。 Further, as described above, in this case, since the through hole 35 is provided so as to straddle the step of the vertical positioning portion 36, the urethane foam flowing from the through hole 35 forms the step of the vertical positioning portion 36. It becomes easy to flow along the wall surface where it does. Furthermore, since the protrusion 37b of the left-right direction positioning portion 37 is spaced from the wall surface forming the step of the up-down direction positioning portion 36 and is provided so as to face the wall surface, the through hole 35 and the wall surface The urethane foam that flows along the horizontal direction positioning portion 37 also flows easily. Such a configuration that facilitates the flow of urethane foam can be applied not only to heat insulating members but also to other special members provided in refrigerator 10 . The special members include, for example, a cover member that covers a portion different from the back surface of the inner box 14, a support member that supports members other than the wire bundles 17L and 17R, and a portion other than between the back surface of the inner box 14 and the wire bundles 17L and 17R. Various members provided in the refrigerator 10 are conceivable, such as a heat insulating member that thermally insulates the portion of the refrigerator 10 and an electrical insulating member that electrically insulates the electrical components of the refrigerator 10 .

第２部分３２は、上下方向から見た断面がほぼ三角形状となるように形成されている。また、第２部分３２は、上下方向の寸法が第１部分３１の上下方向の寸法よりも短くなっている。内箱１４のボックス部２２に熱絶縁部材２１Ｌが取り付けられた状態において、第２部分３２の第１面部３２ａは、内箱１４のボックス部２２の左端面に当接する。これによっても、第２部分３２、ひいては、熱絶縁部材２１Ｌ全体の左右方向の位置決めが行われる。また、内箱１４のボックス部２２に熱絶縁部材２１Ｌが取り付けられた状態において、第２部分３２の第２面部３２ｂは、内箱１４の後面のうちボックス部２２の左側方部分に当接する。これにより、第２部分３２、ひいては、絶絶縁部材２１Ｌ全体の前後方向の位置決めが行われる。 The second portion 32 is formed to have a substantially triangular cross section when viewed in the vertical direction. In addition, the vertical dimension of the second portion 32 is shorter than the vertical dimension of the first portion 31 . The first surface portion 32a of the second portion 32 contacts the left end surface of the box portion 22 of the inner case 14 in a state where the heat insulating member 21L is attached to the box portion 22 of the inner case 14 .

According to this configuration, the wire bundles 17L and 17R can be easily fitted into the support grooves 22L and 22R, and the assembly can be improved. Further, in a state in which the wire bundles 17L and 17R are fitted in the support grooves 22L and 22R, the mechanical load applied to the wire bundles 17L and 17R by the ends of the support grooves 22L and 22R can be reduced. Damage or breakage of 17L and 17R can be prevented.

また、冷蔵庫１０によれば、熱絶縁部材２１Ｌ，２１Ｒは、支持溝２２Ｌ，２２Ｒに隣接する位置に平坦部３３，５３を有する。このような平坦部３３，５３を有する熱絶縁部材２１Ｌ，２１Ｒによれば、内箱１４のボックス部２２の裏面に対向する部分を十分に確保することができる。よって、内箱１４のボックス部２２の裏面に対する熱絶縁部材２１Ｌ，２１Ｒの接触面積を大きく確保することができ、熱絶縁部材２１Ｌ，２１Ｒを安定した状態で取り付けることができる。 Further, according to refrigerator 10, heat insulating members 21L and 21R have flat portions 33 and 53 at positions adjacent to support grooves 22L and 22R. According to the heat insulating members 21L and 21R having such flat portions 33 and 53, it is possible to sufficiently secure the portion of the inner case 14 facing the back surface of the box portion 22.

The occurrence of dew condensation at the portion corresponding to 12 can be prevented more reliably. In addition, the wire bundles 17L and 17R can be stably supported at desired positions, in this case, at the left and right corners of the box portion 22 of the inner casing 14 .

また、冷蔵庫１０によれば、内箱１４の凹凸部２２ｃに熱絶縁部材２１Ｌの凹凸部３７ａが係合した状態において、内箱１４の凹凸部２２ｃと熱絶縁部材２１Ｌの凹凸部３７ａとが対向する部分の少なくとも一部に、発泡ウレタンが流通可能な隙間Ｇが形成されている。この構成によれば、この隙間Ｇに発泡ウレタンが流入することにより、断熱性の向上を図ることができ、また、内箱１４の裏面に対する熱絶縁部材２１Ｌの接着性の向上を図ることができる。特に、本実施形態では、この隙間Ｇ部分に貫通孔３４が設けられるようにしたので、この貫通孔３４を通して隙間Ｇに発泡ウレタンを流入しやすくすることができ、断熱性の一層の向上、および、熱絶縁部材２１Ｌの接着性の一層の向上を図ることができる。 Further, according to the refrigerator 10, when the uneven portion 37a of the heat insulating member 21L is engaged with the uneven portion 22c of the inner box 14, the uneven portion 22c of the inner box 14 and the uneven portion 37a of the heat insulating member 21L face each other. A gap G is formed in at least a part of the portion where the urethane foam can flow. According to this configuration, the urethane foam flows into the gap G, thereby improving the heat insulating property and improving the adhesiveness of the heat insulating member 21L to the back surface of the inner box 14. . In particular, in this embodiment, since the through hole 34 is provided in the gap G, the urethane foam can be easily flowed into the gap G through the through hole 34, further improving heat insulation and , the adhesiveness of the heat insulating member 21L can be further improved.

また、冷蔵庫１０によれば、熱絶縁部材２１Ｌ，２１Ｒは、何れも、内箱１４のボックス部２２の左右の角部を覆う形状となっている。この構成によれば、内箱１４のボックス部２２に対し熱絶縁部材２１Ｌ，２１Ｒを取り付けやすくすることができる。また、内箱１４のボックス部２２に対し熱絶縁部材２１Ｌ，２１Ｒを安定した状態で取り付けることができる。 Further, according to the refrigerator 10 , both the heat insulating members 21</b>L and 21</b>R are shaped to cover the left and right corners of the box portion 22 of the inner case 14 . With this configuration, the heat insulating members 21L and 21R can be easily attached to the box portion 22 of the inner box 14. As shown in FIG. Also, the heat insulating members 21L and 21R can be attached to the box portion 22 of the inner box 14 in a stable state.

また、図１１に例示するように、例えば、支持溝を有しない熱絶縁部材を設けた構成では、二点鎖線で示すように、熱絶縁部材２１Ｌ，２１Ｒの一端側において、曲げられて配置される束線１７Ｌ，１７Ｒの寸法Ｄ１が長くなってしまう。本実施形態に係る冷蔵庫１０によれば、熱絶縁部材２１Ｌ，２１Ｒに設けた支持溝２２Ｌ，２２Ｒに束線１７Ｌ，１７Ｒを嵌め込むようにした。そのため、熱絶縁部材２１Ｌ，２１Ｒの一端側において、曲げられて配置される束線１７Ｌ，１７Ｒの寸法Ｄ２を短くすることができ、束線１７Ｌ，１７Ｒの短縮を図ることができる。 Further, as illustrated in FIG. 11, for example, in a configuration in which a heat insulating member having no support groove is provided, the heat insulating members 21L and 21R are arranged bent at one end side as indicated by the two-dot chain line. The dimension D1 of the bundled wires 17L and 17R becomes long. According to the refrigerator 10 of this embodiment, the wire bundles 17L and 17R are fitted into the support grooves 22L and 22R provided in the heat insulating members 21L and 21R. Therefore, it is possible to shorten the dimension D2 of the wire bundles 17L and 17R that are bent and arranged at one end side of the heat insulating members 21L and 21R, so that the wire bundles 17L and 17R can be shortened.

なお、本実施形態は、上述した一実施形態に限られるものではなく、その要旨を逸脱しない範囲で種々の変形や拡張をすることが可能である。例えば、熱絶縁部材２１Ｌ，２１Ｒは、冷凍温度帯に維持される冷凍室１２以外の貯蔵室、例えば、冷凍温度帯に維持される小冷凍室、製氷室、冷蔵温度帯に維持される冷蔵室、野菜室、チルド室などに対応する部分に設けてもよい。 It should be noted that this embodiment is not limited to the one embodiment described above, and various modifications and extensions can be made without departing from the gist thereof. For example, the heat insulating members 21L and 21R may be used in storage compartments other than the freezer compartment 12 maintained in the freezing temperature range, such as a small freezer compartment maintained in the freezing temperature range, an ice making compartment, and a refrigerating compartment maintained in the refrigerating temperature range. , the vegetable compartment, the chilled compartment, and the like.

また、図１２に例示するように、冷蔵庫１０は、束線１７Ｌ，１７Ｒを支持する支持溝２２Ｌ，２２Ｒを覆うカバー部材６１Ｌ，６１Ｒをさらに備える構成としてもよい。この構成によれば、支持溝２２Ｌ，２２Ｒに支持されている束線１７Ｌ，１７Ｒがさらにカバー部材６１Ｌ，６１Ｒによっても囲まれた状態となり、束線１７Ｌ，１７Ｒの周辺の気密性を向上させて、結露の発生を一層抑制することができる。また、支持溝２２Ｌ，２２Ｒから束線１７Ｌ，１７Ｒが外れてしまうことを防止することができ、束線１７Ｌ，１７Ｒを一層安定した状態で支持することができる。 Moreover, as illustrated in FIG. 12, the refrigerator 10 may further include cover members 61L and 61R that cover the support grooves 22L and 22R that support the wire bundles 17L and 17R. According to this configuration, the wire bundles 17L and 17R supported by the support grooves 22L and 22R are further surrounded by the cover members 61L and 61R, thereby improving the airtightness around the wire bundles 17L and 17R. , the occurrence of dew condensation can be further suppressed. Moreover, it is possible to prevent the wire bundles 17L and 17R from coming off the support grooves 22L and 22R, so that the wire bundles 17L and 17R can be supported in a more stable state.

なお、カバー部材６１Ｌ，６１Ｒは、例えば、シート状の紙テープなどにより構成される。本実施形態に係る冷蔵庫１０によれば、熱絶縁部材２１Ｌ，２１Ｒは、支持溝２２Ｌ，２２Ｒに隣接して平坦部３３，５３を設けている。そのため、このような平坦部３３，５３には、シート状の紙テープを貼りやすく、従って、支持溝２２Ｌ，２２Ｒに支持されている束線１７Ｌ，１７Ｒがカバー部材６１Ｌ，６１Ｒによって覆われた状態を形成しやすくすることができる。 The cover members 61L and 61R are made of, for example, sheet-like paper tape. According to the refrigerator 10 according to this embodiment, the heat insulating members 21L, 21R are provided with the flat portions 33, 53 adjacent to the support grooves 22L, 22R. Therefore, a sheet-like paper tape can be easily attached to the flat portions 33, 53, so that the bundled wires 17L, 17R supported by the support grooves 22L, 22R are covered with the cover members 61L, 61R. can be made easier to form.

また、図１３に例示するように、支持溝２２Ｌ，２２Ｒは、その延伸方向に直交する方向にも拡大部２２Ｌｃ，２２Ｒｃを設けることにより、支持溝２２Ｌ，２２Ｒに束線１７Ｌ，１７Ｒを一層嵌め込みやすくすることができ、また、束線１７Ｌ，１７Ｒに与えられる機械的な負荷を一層軽減することができる。 Further, as illustrated in FIG. 13, the support grooves 22L and 22R are provided with enlarged portions 22Lc and 22Rc in the direction orthogonal to the extending direction thereof, so that the wire bundles 17L and 17R are further fitted into the support grooves 22L and 22R. In addition, the mechanical load applied to the wire bundles 17L and 17R can be further reduced.

また、図１４に例示するように、支持溝２２Ｌ，２２Ｒの拡大部２２Ｌｂ，２２Ｒｂは、その傾斜角度を多段階、例えば、２段階で異ならせるように構成してもよい。この構成によれば、支持溝２２Ｌ，２２Ｒに束線１７Ｌ，１７Ｒを一層嵌め込みやすくすることができ、また、束線１７Ｌ，１７Ｒに与えられる機械的な負荷を一層軽減することができる。なお、図示はしないが、支持溝２２Ｌ，２２Ｒの拡大部２２Ｌａ，２２Ｒａも、その傾斜角度を多段階で異ならせるように構成してもよい。 Further, as illustrated in FIG. 14, the enlarged portions 22Lb and 22Rb of the support grooves 22L and 22R may be configured to have different inclination angles in multiple stages, for example, in two stages. According to this configuration, the wire bundles 17L and 17R can be more easily fitted into the support grooves 22L and 22R, and the mechanical load applied to the wire bundles 17L and 17R can be further reduced. Although not shown, the enlarged portions 22La and 22Ra of the support grooves 22L and 22R may also be configured to have different inclination angles in multiple stages.

冷蔵庫１０は、例えば熱絶縁部材２１Ｌ，２１Ｒを一体的に設けて、この１つの熱絶縁部材により複数の束線１７Ｌ，１７Ｒを支持する構成としてもよい。また、熱絶縁部材に設ける支持溝は、直線状に延びるものに限られず、例えば、その一部あるいは全部が屈曲していたり、蛇行していたりしてもよい。また、支持溝の形状は、熱絶縁部材２１Ｌ，２１Ｒを備えない従来の冷蔵庫における束線１７Ｌ，１７Ｒの配線形状に沿った形状としてもよいし、従来とは異なる配線形状、例えば、束線１７Ｌ，１７Ｒを従来に比べ一層短くできる形状、束線１７Ｌ，１７Ｒを従来に比べ機械室に到達させやすくできる形状など、支持溝の形状に創意工夫を施すようにしてもよい。また、支持部は、連続的に延びる溝状の構成に限られず、例えば、束線１７Ｌ，２１Ｒを部分的に支持するように断続的に設けてもよい。 For example, the refrigerator 10 may be configured such that the heat insulating members 21L and 21R are integrally provided, and the single heat insulating member supports the plurality of wire bundles 17L and 17R. Further, the support groove provided in the heat insulating member is not limited to extending linearly, and may be partially or wholly bent or meandering, for example. Further, the shape of the support groove may follow the wiring shape of the wire bundles 17L and 17R in a conventional refrigerator without the heat insulating members 21L and 21R. , 17R can be made shorter than before, and the shape of the support grooves can be made easier to reach the machine room than before. Further, the supporting portion is not limited to a continuously extending groove-like configuration, and may be intermittently provided so as to partially support the wire bundles 17L and 21R, for example.
