冷蔵庫では、断熱性能を高めるため、外箱本体とは別に断熱材が充填された箱状の背面部材が設けられることがある。その結果、背面部材が、外箱本体の背面側に突出してしまうことがある。 In a refrigerator, in order to improve heat insulation performance, a box-shaped back member filled with a heat insulating material may be provided in addition to the outer box body. As a result, the back member may project to the back side of the outer box body.

特許文献１及び２に記載の冷蔵庫では、補強部材が機械室内に設けられている。このため、背面部材が外箱本体の背面側に突出した場合、外箱本体に、補強部材が設置される部材と併せて意匠用の塗装又はフィルムコートを施したうえ、その外箱本体を背面側に延伸させる必要がある。このため、材料コストが高くなる。また、機械室内の圧縮機、配管、配線等を収納する容積が確保できないおそれがある。 In the refrigerators described in Patent Documents 1 and 2, the reinforcing member is provided in the machine room. For this reason, when the back member protrudes to the back side of the outer box body, the outer box body is given a design coating or film coat together with the member on which the reinforcing member is installed, and then the outer box body is placed on the back side. Need to be stretched to the side. Therefore, the material cost becomes high. In addition, there is a possibility that the capacity for accommodating the compressor, piping, wiring, etc. in the machine room cannot be secured.

本発明は上記の課題を解決するためになされたもので、低コストで外箱本体の変形が抑えられる冷蔵庫を提供することを目的とする。 The present invention has been made to solve the above problems, and an object thereof is to provide a refrigerator in which deformation of an outer box body can be suppressed at low cost.

上記の目的を達成するため、本発明に係る冷蔵庫は、正面側が開口した冷蔵室の下側に形成された、背面側かつ底側が開口した機械室を有する外箱本体と、機械室よりも上側かつ冷蔵室よりも背面側の、外箱本体の背面部分を覆い、内部に断熱材が収容された箱状の背面部材と、機械室に収容される機械部品が載置された台板と、機械室内に設けられた補強部材と、補強部材と台板を連結する連結部材と、を備える。台板は、外箱本体の底側から外箱本体の背面側かつ背面部材の下側まで延在する。補強部材は、台板の上面から鉛直方向に延在して機械室の天井を支持し、かつ機械室の側壁に当接する。連結部材は、補強部材の背面に当接すると共に補強部材に固定された第１固定部及び、台板の上面に沿って背面側に延在すると共に台板に固定された第２固定部を有する。 In order to achieve the above object, the refrigerator according to the present invention includes an outer box main body having a machine room formed on the lower side of a refrigerating room whose front side is open and having a rear side and a bottom side opened, and an upper side of the machine room. And, on the back side of the refrigerating room, covering the back part of the outer box body, a box-shaped back member in which a heat insulating material is housed, and a base plate on which machine parts housed in the machine room are placed, A reinforcing member provided in the machine room and a connecting member connecting the reinforcing member and the base plate are provided. The base plate extends from the bottom side of the outer box body to the back side of the outer box body and below the back member. The reinforcing member extends in the vertical direction from the upper surface of the base plate to support the ceiling of the machine room, and also contacts the side wall of the machine room. The connecting member has a first fixing portion that is in contact with the back surface of the reinforcing member and is fixed to the reinforcing member, and a second fixing portion that extends to the back surface side along the upper surface of the base plate and is fixed to the base plate. .

本発明の構成によれば、補強部材が、台板の上面から鉛直方向に延在して機械室の天井を支持すると共に機械室の側壁に当接している。また、連結部材の第１固定部が補強部材の背面に当接すると共に補強部材に固定され、第２固定部が台板の上面に沿って背面側に延在すると共に台板に固定されている。このため、台板が変形しにくく、意匠用の塗装又はフィルムコートを施した外箱本体を背面側に延伸させる必要がない。さらに、台板が背面部材の下側まで延在するので、圧縮機、配管、配線等を収納する容積を確保することができる。 According to the configuration of the present invention, the reinforcing member extends in the vertical direction from the upper surface of the base plate to support the ceiling of the machine room and is in contact with the side wall of the machine room. Further, the first fixing portion of the connecting member contacts the back surface of the reinforcing member and is fixed to the reinforcing member, and the second fixing portion extends to the rear surface side along the upper surface of the base plate and is fixed to the base plate. . For this reason, the base plate is unlikely to be deformed, and it is not necessary to extend the outer box body, which is coated or film-coated for design purposes, to the back side. Further, since the base plate extends to the lower side of the back surface member, it is possible to secure a volume for accommodating the compressor, piping, wiring, and the like.

（実施の形態１）
実施の形態１に係る冷蔵庫は、底側かつ背面側に機械室が形成された外箱本体と、外箱本体の背面側に突出する背面部材と、を備える冷蔵庫である。この冷蔵庫では、外箱本体を支持する台板が外箱本体から背面部材の下側にまで延在している。そして、冷蔵庫の剛性を高めるため、機械室の内壁を補強する補強部材と、台板と補強部材を連結する連結部材と、を備える。まず、図１Ａ、図１Ｂ及び図２を参照して、冷蔵庫の構成と機械室の位置について説明する。次に、図３を参照して、補強部材と連結部材の構成について説明する。続いて、補強部材と連結部材の作用について説明する。 (Embodiment 1)
The refrigerator according to the first embodiment is a refrigerator including an outer box body having a machine room formed on the bottom side and the back side, and a back member protruding to the back side of the outer box body. In this refrigerator, a base plate supporting the outer box body extends from the outer box body to the lower side of the back member. Further, in order to increase the rigidity of the refrigerator, a reinforcing member that reinforces the inner wall of the machine room and a connecting member that connects the base plate and the reinforcing member are provided. First, the configuration of the refrigerator and the position of the machine room will be described with reference to FIGS. 1A, 1B and 2. Next, configurations of the reinforcing member and the connecting member will be described with reference to FIG. Next, the operation of the reinforcing member and the connecting member will be described.

図１Ａは、本発明の実施の形態１に係る冷蔵庫１Ａを正面側から視たときの斜視図である。図１Ｂは、冷蔵庫１Ａを背面側から視たときの斜視図である。図２は、冷蔵庫１Ａの側面図である。なお、冷蔵庫１Ａは、扉を備えるが、図１Ａ、図１Ｂ及び図２では、理解を容易にするため、その図示を省略している。
冷蔵庫１Ａは、図１Ａに示すように、冷蔵室１００が形成された内箱１０と、内箱１０を収容する外箱２０と、を備えている。 FIG. 1A is a perspective view of a refrigerator 1A according to Embodiment 1 of the present invention when viewed from the front side. FIG. 1B is a perspective view of the refrigerator 1A when viewed from the back side. FIG. 2 is a side view of the refrigerator 1A. Although the refrigerator 1A includes a door, the illustration is omitted in FIGS. 1A, 1B, and 2 for easy understanding.
As shown in FIG. 1A, the refrigerator 1A includes an inner box 10 in which a refrigerating chamber 100 is formed, and an outer box 20 that houses the inner box 10.

内箱１０は、熱可塑性樹脂が真空成形することにより形成されている。そして、内箱１０は、図示しないが、直方体状の外形を有する。内箱１０の内側には、仕切板１１０で仕切られた冷蔵室１００が設けられている。冷蔵室１００では、後述する外箱２０の底板２３の形状にあわせるため、底１１の背面部１１Ｂが正面部１１Ｆよりも高い位置に配置されている。 The inner box 10 is formed by vacuum forming a thermoplastic resin. Although not shown, the inner box 10 has a rectangular parallelepiped outer shape. Inside the inner box 10, a refrigerating chamber 100 partitioned by a partition plate 110 is provided. In the refrigerating compartment 100, the back surface portion 11B of the bottom 11 is arranged at a position higher than the front surface portion 11F in order to match the shape of the bottom plate 23 of the outer box 20 described later.

また、内箱１０には、図示しない冷却器が設けられている。冷蔵庫１Ａは、冷却器、圧縮機、凝縮器及び膨張弁の冷凍サイクル用の機械部品を備えている。内箱１０内の空気は、これら冷凍サイクル用の機械部品のうち、冷却器によって冷却される。そして、内箱１０は、その内部の空気を外部から断熱するため、外箱２０に収容されている。さらに断熱性を高めるため、内箱１０と外箱２０との間には、硬質ウレタンフォームで形成された、図示しない断熱材が充填されている。 Further, the inner box 10 is provided with a cooler (not shown). The refrigerator 1A includes mechanical components for a refrigeration cycle such as a cooler, a compressor, a condenser, and an expansion valve. The air in the inner box 10 is cooled by a cooler among the mechanical parts for the refrigeration cycle. The inner box 10 is housed in the outer box 20 in order to insulate the air therein from the outside. In order to further enhance the heat insulating property, a heat insulating material (not shown) made of hard urethane foam is filled between the inner box 10 and the outer box 20.

一方、外箱２０は、板金をプレス加工して成形した複数の部材が組み合わされることにより形成されている。詳細には、外箱２０は、図１Ａ及び図１Ｂに示すように、天板部２１１及び側板部２１２、２１３を有する外箱本体２１と、外箱本体２１の背面側を塞ぐ背面部材２２と、天板部２１１と対向する底板２３及び台板２４と、を備えている。これらの部材は、ロールフォーミング、プレス加工等により成形されている。 On the other hand, the outer box 20 is formed by combining a plurality of members formed by pressing a sheet metal. Specifically, as shown in FIGS. 1A and 1B, the outer box 20 includes an outer box body 21 having a top plate portion 211 and side plate portions 212 and 213, and a back member 22 that closes the back side of the outer box body 21. The bottom plate 23 and the base plate 24 facing the top plate portion 211 are provided. These members are formed by roll forming, press working, or the like.

外箱本体２１は、板金を断面コの字状に折り曲げることにより形成されている。これにより、外箱本体２１では、上述した天板部２１１と側板部２１２、２１３が一体的に形成されている。また、天板部２１１と側板部２１２、２１３には、意匠性を高めるため、塗装又はフィルムコートが施されている。そして、外箱本体２１は、図１Ａに示すように、天板部２１１の板面をＺ方向、側板部２１２、２１３の板面をＸ方向に向けて配置されている。なお、図示しないが、側板部２１２、２１３の正面側端面には、扉を取り付けるためのヒンジが固定される。 The outer box body 21 is formed by bending a sheet metal into a U-shaped cross section. As a result, in the outer box body 21, the top plate portion 211 and the side plate portions 212 and 213 described above are integrally formed. Further, the top plate portion 211 and the side plate portions 212 and 213 are coated or film-coated in order to enhance the design. As shown in FIG. 1A, the outer box body 21 is arranged with the plate surface of the top plate portion 211 facing the Z direction and the plate surfaces of the side plate portions 212 and 213 facing the X direction. Although not shown, hinges for attaching the door are fixed to the front end surfaces of the side plate portions 212 and 213.

背面部材２２は、図示しないが、開口した面を有する直方体の箱の形状に形成されている。そして、背面部材２２は、その開口した面を正面側に向けて外箱本体２１の側板部２１２と２１３の間に嵌め込まれている。背面部材２２は、外箱本体２１の背面側に位置するため、天板部２１１と側板部２１２、２１３と異なり、目立ちにくい。このため、背面部材２２には、高い意匠性は不要である。そこで、背面部材２２には、材料コストを低くするため、塗装又はフィルムコートが施されていない。また、背面部材２２内には、内箱１０と外箱２０との間と同じ、硬質ウレタンフォームで形成された断熱材が充填されている。 Although not shown, the back member 22 is formed in the shape of a rectangular parallelepiped box having an open surface. The back member 22 is fitted between the side plate portions 212 and 213 of the outer box body 21 with the open surface facing the front side. Since the back member 22 is located on the back side of the outer box body 21, unlike the top plate portion 211 and the side plate portions 212 and 213, it is less noticeable. Therefore, the back member 22 does not need to have high designability. Therefore, the back member 22 is not painted or film-coated in order to reduce the material cost. Further, the back member 22 is filled with the same heat insulating material formed of hard urethane foam as between the inner case 10 and the outer case 20.

一方、底板２３は、段差を有する形状に形成されている。詳細には、図１Ｂに示すように、底板２３の正面部２３Ｆと背面部２３Ｂとの間に、背面側に向かうほど高くなる傾斜部２３Ｉが形成されている。そして、底板２３の背面部２３Ｂは、正面部２３Ｆよりも高い。そして、底板２３の正面部２３Ｆは、外箱本体２１の下端に配置されている。また、底板２３の正面部２３Ｆと背面部２３Ｂは、外箱本体２１の天板部２１１と平行である。これにより、底板２３の傾斜部２３Ｉと背面部２３Ｂの下には、空間が形成されている。冷蔵庫１Ａでは、この空間を機械室２００として使用する。底板２３の傾斜部２３Ｉと背面部２３Ｂの下には、機械室２００に載置する圧縮機、冷媒管、電線、凝縮器等の機械部品を支持する台板２４が配置されている。 On the other hand, the bottom plate 23 is formed in a shape having a step. More specifically, as shown in FIG. 1B, an inclined portion 23I that becomes higher toward the rear side is formed between the front portion 23F and the rear portion 23B of the bottom plate 23. The back surface portion 23B of the bottom plate 23 is higher than the front surface portion 23F. The front portion 23F of the bottom plate 23 is arranged at the lower end of the outer box body 21. The front surface portion 23F and the back surface portion 23B of the bottom plate 23 are parallel to the top plate portion 211 of the outer box body 21. As a result, a space is formed below the inclined portion 23I and the back surface portion 23B of the bottom plate 23. In the refrigerator 1A, this space is used as the machine room 200. Below the inclined portion 23I and the back surface portion 23B of the bottom plate 23, a base plate 24 that supports mechanical components such as a compressor, a refrigerant pipe, an electric wire, and a condenser mounted in the machine chamber 200 is arranged.

台板２４は、矩形状の板の形状に形成されている。また、台板２４は、図１Ｂ及び図２に示すように、矩形の長辺側の端部が折り曲げられている。台板２４は、格子状かつ上側に凸状のビード２４１を有する。これにより、台板２４は、剛性が高められている。台板２４は、底板２３の正面部２３Ｆの背面側に配置され、外箱本体２１の下端に固定されている。台板２４は、図２に示すように、外箱本体２１よりも背面側に突出している。 The base plate 24 is formed in the shape of a rectangular plate. Further, as shown in FIGS. 1B and 2, the base plate 24 has a rectangular long side end bent. The base plate 24 has a bead 241 having a lattice shape and a convex shape on the upper side. As a result, the base plate 24 has increased rigidity. The base plate 24 is arranged on the back surface side of the front portion 23F of the bottom plate 23 and is fixed to the lower end of the outer box body 21. As shown in FIG. 2, the base plate 24 projects rearward from the outer box body 21.

上述したように、背面部材２２には、硬質ウレタンフォームの断熱材が充填されている。硬質ウレタンフォームは、低コストであるものの、真空断熱材よりも断熱性が低い。ここで、真空断熱材とは、多孔質材料と、多孔質材料を真空状態で密封するフィルムと、を備える断熱材のことである。そこで、冷蔵庫１Ａでは、背面部材２２の図２に示すＹ方向の厚みを大きくしている。そして、背面部材２２に充填される硬質ウレタンフォームの体積を大きくしている。さらに、冷蔵庫１Ａでは、外箱本体２１内の内箱１０を収容する領域を確保するため、背面部材２２を外箱本体２１よりも背面側に出っ張らしている。台板２４は、背面部材２２が外箱本体２１から出っ張った、その距離Ｌと同じ距離だけ、外箱本体２１から背面側に突出している。これにより、機械室２００の、圧縮機、冷媒管、電線等を収容する収納容積を確保している。 As described above, the back member 22 is filled with the heat insulating material of rigid urethane foam. Although rigid urethane foam is low in cost, it has a lower heat insulating property than a vacuum heat insulating material. Here, the vacuum heat insulating material is a heat insulating material including a porous material and a film that seals the porous material in a vacuum state. Therefore, in the refrigerator 1A, the thickness of the back member 22 in the Y direction shown in FIG. 2 is increased. Then, the volume of the hard urethane foam filled in the back member 22 is increased. Further, in the refrigerator 1 </ b> A, the back member 22 is protruded to the back side of the outer box body 21 in order to secure a region for housing the inner box 10 in the outer box body 21. The base plate 24 protrudes from the outer box body 21 to the back side by the same distance L as the back member 22 projects from the outer box body 21. This secures a storage volume of the machine room 200 for storing the compressor, the refrigerant pipe, the electric wire, and the like.

一方、台板２４が外箱本体２１から突出する結果、台板２４の突出した部分は、十分な剛性を有さないおそれがある。また、外箱本体２１は、背面側が開口した機械室２００を有するため、その部分で十分な剛性を有さないおそれがある。その結果、台板２４が変形してしまうおそれがある。そこで、冷蔵庫１Ａには、剛性を高めるため、機械室２００の内壁を補強する補強部材３０と、台板２４を補強部材３０に連結させる連結部材４０と、が設けられている。次に、図３を参照して、補強部材と連結部材の構成について説明する。 On the other hand, as a result of the base plate 24 protruding from the outer box body 21, the protruding portion of the base plate 24 may not have sufficient rigidity. Further, since the outer box body 21 has the machine room 200 having an opening on the back side, there is a possibility that the outer box body 21 does not have sufficient rigidity. As a result, the base plate 24 may be deformed. Therefore, the refrigerator 1A is provided with a reinforcing member 30 that reinforces the inner wall of the machine room 200 and a connecting member 40 that connects the base plate 24 to the reinforcing member 30 in order to increase rigidity. Next, configurations of the reinforcing member and the connecting member will be described with reference to FIG.

図３は、冷蔵庫１Ａの背面側かつ底側の拡大斜視図である。なお、図３では、理解を容易にするため、冷蔵庫１Ａの背面側の左側部分を省略している。
図３に示すように、冷蔵庫１Ａは、機械室２００を補強する補強部材３０と、補強部材３０と台板２４とを接続する連結部材４０と、をさらに備えている。
なお、補強部材３０と連結部材４０は、図３に示す冷蔵庫１Ａの背面側の左側部分のほか、右側部分にも設けられている。その右側部分にある補強部材３０と連結部材４０は、左側部分にある補強部材３０と連結部材４０と左右対称であることを除いて、同じ構成である。このため、以下の説明では、右側部分にある補強部材３０と連結部材４０の説明を省略する。 FIG. 3 is an enlarged perspective view of the rear side and the bottom side of the refrigerator 1A. In FIG. 3, the left side portion on the back side of the refrigerator 1A is omitted for easy understanding.
As shown in FIG. 3, the refrigerator 1 </ b> A further includes a reinforcing member 30 that reinforces the machine room 200, and a connecting member 40 that connects the reinforcing member 30 and the base plate 24.
The reinforcing member 30 and the connecting member 40 are provided not only on the left side portion on the back side of the refrigerator 1A shown in FIG. 3 but also on the right side portion. The reinforcing member 30 and the connecting member 40 in the right side portion have the same configuration except that the reinforcing member 30 and the connecting member 40 in the left side portion are symmetrical. Therefore, in the following description, the description of the reinforcing member 30 and the connecting member 40 on the right side is omitted.

補強部材３０は、側桁と呼ばれるＬ字状の部材である。補強部材３０は、Ｚ方向に延在する柱状の鉛直部３１と、鉛直部３１の下端から正面方向に延在する桁状の水平部３２と、を有する。 The reinforcing member 30 is an L-shaped member called a side girder. The reinforcing member 30 has a column-shaped vertical portion 31 extending in the Z direction, and a girder-shaped horizontal portion 32 extending from the lower end of the vertical portion 31 in the front direction.

鉛直部３１は、図示しないが、コの字状の断面を有する柱の形状に形成されている。鉛直部３１は、その開口側の端面を機械室２００の側壁である側板部２１２に当接させている。鉛直部３１は、図３に示すように、側板部２１２の背面側の端面に沿って鉛直方向に延在している。鉛直部３１は、側板部２１２に設けられた、図示しない凹部に係合する爪３１１を有する。鉛直部３１は、その凹部に爪３１１が係合することにより、側板部２１２に固定されている。鉛直部３１は、側板部２１２に沿って延在すると共に固定されることにより、側板部２１２を補強している。 Although not shown, the vertical portion 31 is formed in the shape of a column having a U-shaped cross section. The vertical portion 31 has its end face on the opening side brought into contact with the side plate portion 212 which is the side wall of the machine room 200. As shown in FIG. 3, the vertical portion 31 extends in the vertical direction along the rear end surface of the side plate portion 212. The vertical portion 31 has a claw 311 provided in the side plate portion 212, which engages with a recess (not shown). The vertical portion 31 is fixed to the side plate portion 212 by the claw 311 engaging with the recess. The vertical portion 31 extends along the side plate portion 212 and is fixed to reinforce the side plate portion 212.

また、鉛直部３１は、台板２４から機械室２００の天井である、底板２３の背面部２３Ｂへ延在している。そして、鉛直部３１の上端は、図示しないが、底板２３の背面部２３Ｂに当接している。これにより、鉛直部３１は、底板２３を支持して、機械室２００の変形を防止している。また、冷蔵庫１Ａの剛性を高めている。鉛直部３１の下端は、水平部３２によって支持されている。 The vertical portion 31 extends from the base plate 24 to the back surface portion 23B of the bottom plate 23, which is the ceiling of the machine room 200. Although not shown, the upper end of the vertical portion 31 is in contact with the back surface portion 23B of the bottom plate 23. Thereby, the vertical portion 31 supports the bottom plate 23 and prevents the machine room 200 from being deformed. Further, the rigidity of the refrigerator 1A is increased. The lower end of the vertical portion 31 is supported by the horizontal portion 32.

水平部３２は、図３に示す側部３２１と、図示しない底部と、を有する断面逆Ｌ字状に形成されている。水平部３２の側部３２１は、底部の左端に配置されている。 The horizontal portion 32 is formed in an inverted L-shaped cross section having a side portion 321 shown in FIG. 3 and a bottom portion (not shown). The side part 321 of the horizontal part 32 is arranged at the left end of the bottom part.

水平部３２は、上述した断面形状で、図３に示すように、鉛直部３１の下端から正面方向に延在している。水平部３２の端部は、図示しないが、機械室２００の正面壁である、底板２３の傾斜部２３Ｉに当接している。また、水平部３２の底部は、台板２４に当接している。そして、水平部３２の底部は、台板２４にネジ留め又は溶接されている。水平部３２全体は、底部がネジ留め又は溶接されることで、台板２４に固定されている。その結果、水平部３２は、鉛直部３１の下端を支えて、鉛直部３１が正面側へ倒れたり、その位置がずれたりすることを防止している。鉛直部３１の下端は、水平部３２に支持されるほか、連結部材４０にも支持されている。 The horizontal portion 32 has the above-described cross-sectional shape, and as shown in FIG. 3, extends from the lower end of the vertical portion 31 in the front direction. Although not shown, the end of the horizontal portion 32 is in contact with the inclined portion 23I of the bottom plate 23, which is the front wall of the machine room 200. The bottom of the horizontal portion 32 is in contact with the base plate 24. The bottom of the horizontal portion 32 is screwed or welded to the base plate 24. The entire horizontal portion 32 is fixed to the base plate 24 by screwing or welding the bottom portion. As a result, the horizontal portion 32 supports the lower end of the vertical portion 31 to prevent the vertical portion 31 from falling to the front side or shifting its position. The lower end of the vertical portion 31 is supported by the horizontal portion 32 and also by the connecting member 40.

連結部材４０は、Ｌ字金具と呼ばれる部材である。連結部材４０は、細長い鋼板が長手方向に９０°折り曲げられることにより形成されている。連結部材４０は、図３に示すように、ＸＺ平面に平行な鉛直板４１と、鉛直板４１の下端に設けられ、ＸＹ面に平行な水平板４２と、を有している。 The connecting member 40 is a member called an L-shaped metal fitting. The connecting member 40 is formed by bending an elongated steel plate 90 ° in the longitudinal direction. As shown in FIG. 3, the connecting member 40 has a vertical plate 41 parallel to the XZ plane and a horizontal plate 42 provided at the lower end of the vertical plate 41 and parallel to the XY plane.

鉛直板４１は、矩形状に形成されている。鉛直板４１は、長手方向を上方向に向け、かつ板面を補強部材３０の鉛直部３１に当接させた状態に配置されている。鉛直板４１は、貫通孔４１１を有している。鉛直板４１は、その貫通孔４１１に挿通されたネジ４２１が補強部材３０のネジ孔に取り付けられることによって、補強部材３０に固定される。鉛直板４１の下端は、水平板４２の正面側の端部に連続している。 The vertical plate 41 is formed in a rectangular shape. The vertical plate 41 is arranged such that its longitudinal direction is directed upward and its plate surface is in contact with the vertical portion 31 of the reinforcing member 30. The vertical plate 41 has a through hole 411. The vertical plate 41 is fixed to the reinforcing member 30 by attaching the screw 421 inserted in the through hole 411 to the screw hole of the reinforcing member 30. The lower end of the vertical plate 41 is continuous with the front end of the horizontal plate 42.

水平板４２は、鉛直板４１と同じ大きさの矩形の形状に形成されている。そして、水平板４２の長手方向は、背面方向に向けられている。図示しないが、水平板４２は、台板２４の背面側端部にある折り返し部２４２まで延在して、その先端が折り返し部２４２に当接している。また、水平板４２の板面は、台板２４の板面に当接している。水平板４２は、鉛直板４１と同様に、図示しない貫通孔を有する。水平板４２は、その貫通孔に挿通されたネジ４２１が台板２４のネジ孔に取り付けられることにより、台板２４に固定される。 The horizontal plate 42 is formed in a rectangular shape having the same size as the vertical plate 41. Then, the longitudinal direction of the horizontal plate 42 is oriented toward the back surface. Although not shown, the horizontal plate 42 extends to the folded-back portion 242 at the rear end portion of the base plate 24, and the tip thereof is in contact with the folded-back portion 242. The plate surface of the horizontal plate 42 is in contact with the plate surface of the base plate 24. The horizontal plate 42, like the vertical plate 41, has a through hole (not shown). The horizontal plate 42 is fixed to the base plate 24 by attaching the screws 421 inserted in the through holes to the screw holes of the base plate 24.

連結部材４０は、上述したように、鉛直板４１が補強部材３０に固定され、水平板４２が台板２４に固定されている。これにより、連結部材４０は、台板２４を補強部材３０に連結している。その結果、台板２４が変形しにくい。次に、図２を参照して、補強部材３０と連結部材４０の作用について説明する。 As described above, in the connecting member 40, the vertical plate 41 is fixed to the reinforcing member 30, and the horizontal plate 42 is fixed to the base plate 24. Accordingly, the connecting member 40 connects the base plate 24 to the reinforcing member 30. As a result, the base plate 24 is less likely to be deformed. Next, the operation of the reinforcing member 30 and the connecting member 40 will be described with reference to FIG.

冷蔵庫１Ａは、設置場所に搬送されるまでの間に、その搬送作業で、図２に示す背面側に傾けられることがある。この場合、機械室２００に大きな荷重がかかりやすい。しかし、冷蔵庫１Ａは、機械室２００の天井を支えると共に、機械室２００の側壁に当接する鉛直部３１を有する補強部材３０を備えている。これにより、外箱本体２１は、荷重を支えるのに十分な剛性を有する。このため、機械室２００が変形しにくい。また、台板２４は、連結部材４０の水平板４２に補強されているので、変形しにくい。その結果、冷蔵庫１Ａでは、台板２４の変形による設置時のガタつきが生じにくい。 The refrigerator 1A may be tilted to the back side shown in FIG. 2 during its transportation work before being transported to the installation location. In this case, a large load is likely to be applied to the machine room 200. However, the refrigerator 1 </ b> A includes the reinforcing member 30 that supports the ceiling of the machine room 200 and that has the vertical portion 31 that abuts on the side wall of the machine room 200. As a result, the outer box body 21 has sufficient rigidity to support the load. Therefore, the machine room 200 is unlikely to be deformed. Further, since the base plate 24 is reinforced by the horizontal plate 42 of the connecting member 40, it is difficult to deform. As a result, in the refrigerator 1A, rattling at the time of installation due to the deformation of the base plate 24 is unlikely to occur.

以上のように、本発明の実施の形態１に係る冷蔵庫１Ａは、補強部材３０と台板２４を連結する連結部材４０を備えている。そして、連結部材４０は、台板２４に沿って背面側へ延在すると共に、台板２４に固定された水平板４２を有する。このため、台板２４が連結部材４０によって補強され、台板２４が変形しにくい。 As described above, the refrigerator 1A according to Embodiment 1 of the present invention includes the connecting member 40 that connects the reinforcing member 30 and the base plate 24. The connecting member 40 has a horizontal plate 42 that extends to the back side along the base plate 24 and is fixed to the base plate 24. Therefore, the base plate 24 is reinforced by the connecting member 40, and the base plate 24 is less likely to be deformed.

また、冷蔵庫１Ａでは、外箱本体２１を背面側に延伸させずに、背面部材２２を背面側に出っ張らせている。すなわち、冷蔵庫１Ａでは、高い意匠性が要求される外箱本体２１の背面側への厚みをそのままにして、意匠性が要求されない背面部材２２の厚みを大きくしている。外箱本体２１は、背面部材２２よりも製造コストが高い。このため、冷蔵庫１Ａでは、背面部材２２の厚みを大きくすることにより、製造コストを低くすることができる。 In addition, in the refrigerator 1A, the outer case body 21 is not extended to the back side, but the back member 22 is projected to the back side. That is, in the refrigerator 1A, the thickness of the back member 22 that does not require design is increased while leaving the thickness of the back side of the outer box body 21 that requires high design. The outer box body 21 has a higher manufacturing cost than the back member 22. Therefore, in the refrigerator 1A, the manufacturing cost can be reduced by increasing the thickness of the back member 22.

（実施の形態２）
実施の形態１に係る冷蔵庫１Ａでは、連結部材４０の水平板４２が鉛直板４１の下端に直接接続されている。これに対して、実施の形態２に係る冷蔵庫１Ｂでは、鉛直板５１と水平板５２が斜材５３によって接続されている。以下、図４及び図５を参照して、実施の形態２に係る冷蔵庫１Ｂを説明する。実施の形態２では、実施の形態１と異なる構成について説明する。 (Embodiment 2)
In the refrigerator 1A according to the first embodiment, the horizontal plate 42 of the connecting member 40 is directly connected to the lower end of the vertical plate 41. On the other hand, in the refrigerator 1B according to the second embodiment, the vertical plate 51 and the horizontal plate 52 are connected by the diagonal member 53. Hereinafter, the refrigerator 1B according to the second embodiment will be described with reference to FIGS. 4 and 5. In the second embodiment, a configuration different from that of the first embodiment will be described.

図４は、実施の形態２に係る冷蔵庫１Ｂの背面側かつ底側の拡大斜視図である。図５は、冷蔵庫１Ｂが備える連結部材５０Ｒの斜視図である。
図４に示すように、冷蔵庫１Ｂは、補強部材３０の鉛直部３１と台板２４を連結する連結部材５０Ｒ、５０Ｌを備えている。そして、連結部材５０Ｒは、鉛直板５１及び水平板５２と、鉛直板５１と水平板５２を接続する斜材５３と、を有する。
なお、連結部材５０Ｌは、連結部材５０Ｒと左右対称であることを除いて、連結部材５０Ｒと同じ構成である。このため、以下の説明では、連結部材５０Ｌの説明を省略する。 FIG. 4 is an enlarged perspective view of the rear side and the bottom side of the refrigerator 1B according to the second embodiment. FIG. 5 is a perspective view of the connecting member 50R included in the refrigerator 1B.
As shown in FIG. 4, the refrigerator 1B includes connecting members 50R and 50L that connect the vertical portion 31 of the reinforcing member 30 and the base plate 24. The connecting member 50R includes a vertical plate 51 and a horizontal plate 52, and a diagonal member 53 connecting the vertical plate 51 and the horizontal plate 52.
The connecting member 50L has the same configuration as the connecting member 50R except that the connecting member 50L is bilaterally symmetrical. Therefore, the description of the connecting member 50L will be omitted in the following description.

鉛直板５１と水平板５２は、それぞれ、矩形状に形成されている。鉛直板５１の板面は、ＸＺ平面に平行に向けられている。一方、水平板５２の板面は、ＸＹ平面に向けられている。 The vertical plate 51 and the horizontal plate 52 are each formed in a rectangular shape. The plate surface of the vertical plate 51 is oriented parallel to the XZ plane. On the other hand, the plate surface of the horizontal plate 52 faces the XY plane.

また、鉛直板５１と水平板５２には、ネジを挿通させるため、バーリング加工されることにより、孔の回りにフランジ部５１１、５２１を有する貫通孔５１２と５２２が形成されている。また、フランジ部５１１、５２１を有しない貫通孔５１３と５２３が形成されている。
なお、本明細書では、鉛直板５１に形成された貫通孔５１２、５１３を第１貫通孔、貫通孔５１２、５１３に挿通されるネジを第１締結部材ともいう。また、水平板５２に形成された貫通孔５２２、５２３を第２貫通孔、貫通孔５２２、５２３に挿通されるネジを第２締結部材ともいう。 In addition, through-holes 512 and 522 having flanges 511 and 521 are formed around the holes by burring in the vertical plate 51 and the horizontal plate 52 in order to insert screws. Further, through holes 513 and 523 having no flange portions 511 and 521 are formed.
In the present specification, the through holes 512 and 513 formed in the vertical plate 51 are also referred to as first through holes, and the screw inserted into the through holes 512 and 513 is also referred to as a first fastening member. Further, the through holes 522 and 523 formed in the horizontal plate 52 are also referred to as second through holes, and the screws inserted into the through holes 522 and 523 are also referred to as second fastening members.

貫通孔５１２と５２２、貫通孔５１３と５２３は、鉛直板５１の、水平板５２側の板面の延長平面と、水平板５２の、鉛直板５１側の板面の延長平面と、が交差して形成される中心線ＣＬから等距離に形成されている。これにより、貫通孔５１２と５２２、貫通孔５１３と５２３は、鉛直板５１の板面が水平にされ、水平板５２の板面が鉛直にされても、使用可能に形成されている。 The through holes 512 and 522 and the through holes 513 and 523 intersect the extension plane of the plate surface of the vertical plate 51 on the horizontal plate 52 side and the extension plane of the plate surface of the horizontal plate 52 on the vertical plate 51 side. Are formed equidistant from the center line CL formed by Accordingly, the through holes 512 and 522 and the through holes 513 and 523 are formed so as to be usable even when the plate surface of the vertical plate 51 is horizontal and the plate surface of the horizontal plate 52 is vertical.

一方、斜材５３は、板面を鉛直板５１に対して垂直かつ、水平板５２に対して垂直に向けている。そして、斜材５３は、水平板５２から鉛直板５１に向かって延在している。その延在する方向は、水平板５２に対して斜め４５°の方向である。これにより、斜材５３は、鉛直板５１と水平板５２を接続している。また、斜材５３には、図５の＋Ｘ側に凸状で、斜材５３が延在する方向と同じ方向に延在するビード５３１を有している。これにより、斜材５３は、連結部材５０Ｒの剛性を高めている。 On the other hand, the diagonal member 53 has its plate surface oriented perpendicular to the vertical plate 51 and perpendicular to the horizontal plate 52. The diagonal member 53 extends from the horizontal plate 52 toward the vertical plate 51. The extending direction is an angle of 45 ° with respect to the horizontal plate 52. Thereby, the diagonal member 53 connects the vertical plate 51 and the horizontal plate 52. Further, the diagonal member 53 has a bead 531 that is convex toward the + X side in FIG. 5 and extends in the same direction as the direction in which the diagonal member 53 extends. Thereby, the diagonal member 53 enhances the rigidity of the connecting member 50R.

図４に戻って、台板２４の背面側の右側部分には、上述した形状の連結部材５０Ｒが設けられている。また、その反対の左側部分には、連結部材５０Ｒと左右対称な形状を有する連結部材５０Ｌが設けられている。ここで、連結部材５０Ｌは、連結部材５０Ｒの鉛直板５１を水平にし、かつ水平板５２を鉛直にすることで得られる連結部材である。そして、連結部材５０Ｒ、５０Ｌは、上述した貫通孔５１２、５１３、５２２及び、５２３に挿通されたネジによって、補強部材３０の鉛直部３１と台板２４に固定されている。これにより、連結部材５０Ｒ、５０Ｌは、補強部材３０と台板２４を連結している。また、連結部材５０Ｒ、５０Ｌは、台板２４を補強している。 Returning to FIG. 4, the connecting member 50R having the above-described shape is provided on the right side portion on the back surface side of the base plate 24. Further, on the opposite left side portion, a connecting member 50L having a symmetrical shape with the connecting member 50R is provided. Here, the connecting member 50L is a connecting member obtained by making the vertical plate 51 of the connecting member 50R horizontal and making the horizontal plate 52 vertical. The connecting members 50R and 50L are fixed to the vertical portion 31 of the reinforcing member 30 and the base plate 24 by the screws inserted into the through holes 512, 513, 522, and 523 described above. Thereby, the connecting members 50R and 50L connect the reinforcing member 30 and the base plate 24. Further, the connecting members 50R and 50L reinforce the base plate 24.

なお、連結部材５０Ｒ、５０Ｌの作用は、斜材５３によって連結部材５０Ｒ、５０Ｌの剛性が高められていることを除いて、実施の形態１の連結部材４０と同様である。 The operation of the connecting members 50R and 50L is the same as that of the connecting member 40 of the first embodiment except that the diagonal members 53 increase the rigidity of the connecting members 50R and 50L.

以上のように、実施の形態２に係る冷蔵庫１Ｂでは、連結部材５０Ｒ、５０Ｌが斜材５３を有するので、連結部材５０Ｒ、５０Ｌの剛性が高い。また、連結部材５０Ｒ、５０Ｌが台板２４を補強するので、台板２４が変形しにくい。 As described above, in the refrigerator 1B according to Embodiment 2, since the connecting members 50R and 50L have the diagonal members 53, the connecting members 50R and 50L have high rigidity. Moreover, since the connecting members 50R and 50L reinforce the base plate 24, the base plate 24 is less likely to be deformed.

（実施の形態３）
実施の形態１と２では、冷蔵庫１Ａ、１Ｂに設けられた機械室２００の背面側が開口したままである。これに対して、実施の形態３に係る冷蔵庫１Ｃでは、機械室２００の開口が、背面カバー６０と、連結部７２を有する側面カバー７０Ｒ、７０Ｌと、によって塞がれている。以下、図６−図８を参照して、実施の形態３に係る冷蔵庫１Ｃを説明する。実施の形態３では、実施の形態１及び２と異なる構成について説明する。 (Embodiment 3)

なお、図７では、側面カバー７０Ｒ、７０Ｌの形状、大きさの理解を容易にするため、背面カバー６０の正面側に位置する側面カバー７０Ｒ、７０Ｌを、背面カバー６０の背面側に配置している。
冷蔵庫１Ｃは、図６及び図７に示すように、機械室２００の開口を塞ぐ背面カバー６０と、背面カバー６０と外箱本体２１の側板部２１２、２１３との間の隙間を塞ぐ側面カバー７０Ｒ、７０Ｌと、を備えている。
なお、側面カバー７０Ｒ、７０Ｌの構成は、左右対称であることを除いて、同じである。以下、側面カバー７０Ｒの構成を説明し、側面カバー７０Ｌの説明を省略する。 FIG. 6 is a perspective view of the back cover 60 and the side covers 70R and 70L of the machine room 200 included in the refrigerator 1C according to the third embodiment. FIG. 7 is a perspective view of the back cover 60 and the side covers 70R and 70L of the machine room 200 as viewed from the back side. FIG. 8 is a perspective view of the side cover 70R as viewed from the front side.
In FIG. 7, in order to facilitate understanding of the shapes and sizes of the side covers 70R and 70L, the side covers 70R and 70L located on the front side of the back cover 60 are arranged on the back side of the back cover 60. There is.
As shown in FIGS. 6 and 7, the refrigerator 1C includes a rear cover 60 that closes the opening of the machine room 200, and a side cover 70R that closes a gap between the rear cover 60 and the side plate portions 212 and 213 of the outer box body 21. , 70L.
The side covers 70R and 70L have the same configuration except that they are symmetrical. Hereinafter, the configuration of the side cover 70R will be described, and the description of the side cover 70L will be omitted.

背面カバー６０は、図６に示すように、長手方向を左右方向、すなわち、Ｘ方向に向けた矩形の形状に形成されている。そのＸ方向の長さは、背面部材２２、台板２４のＸ方向の長さと同じである。また、Ｚ方向の長さは、図示しないが、Ｙ方向視の機械室２００のＺ方向長さよりも長い。そして、背面カバー６０には、図６に示すように、プレス加工によって、複数個の通気孔６１と背面側に凸形状のビード６２が形成されている。 As shown in FIG. 6, the back cover 60 is formed in a rectangular shape whose longitudinal direction is the left-right direction, that is, the X direction. The length in the X direction is the same as the length in the X direction of the back surface member 22 and the base plate 24. Although not shown, the Z-direction length is longer than the Z-direction length of the machine room 200 as viewed in the Y direction. As shown in FIG. 6, the back cover 60 is formed with a plurality of vent holes 61 and a bead 62 having a convex shape on the back side by press working.

また、背面カバー６０の上端近傍には、図示しない貫通孔が複数個、形成され、それらの貫通孔にネジ６３が挿通されている。背面カバー６０は、ネジ６３が背面部材２２の下部に取り付けられることで、背面部材２２に固定される。そして、背面カバー６０は、機械室２００の背面側を覆っている。 Further, a plurality of through holes (not shown) are formed in the vicinity of the upper end of the back cover 60, and the screws 63 are inserted into these through holes. The back cover 60 is fixed to the back member 22 by attaching the screws 63 to the lower portion of the back member 22. The back cover 60 covers the back side of the machine room 200.

一方、側面カバー７０Ｒは、図８に示すように、カバー部７１と、カバー部７１の下端に設けられた連結部７２と、を備える。なお、本明細書では、側面カバー７０Ｒを、機械室２００の背面側の一部を覆うことから、機械室背面板ともいう。 On the other hand, the side cover 70R includes a cover portion 71 and a connecting portion 72 provided at the lower end of the cover portion 71, as shown in FIG. In the present specification, the side cover 70R covers a part of the back surface side of the machine room 200, and thus is also referred to as a machine room rear plate.

カバー部７１は、板金がＬ字状に折り曲げられることにより形成された背面部７１１及び側面部７１２を有する。そして、背面部７１１は、側面部７１２の背面側の端部に位置する。側面部７１２には、換気用の通気孔７１３が形成されている。 The cover portion 71 has a back surface portion 711 and a side surface portion 712 formed by bending a metal plate into an L shape. The back surface portion 711 is located at the end portion on the back surface side of the side surface portion 712. Vent holes 713 for ventilation are formed in the side surface portion 712.

冷蔵庫１Ｃでは、図示しないが、背面部７１１が台板２４の背面側に配置され、側面部７１２が台板２４の右側、すなわち＋Ｘ側に配置される。これにより、カバー部７１は、背面カバー６０と外箱本体２１の側板部２１２との隙間を塞いでいる。カバー部７１は、図８に示すように、連結部７２とつながっている。 In the refrigerator 1C, although not shown, the back surface portion 711 is arranged on the back surface side of the base plate 24, and the side surface portion 712 is arranged on the right side of the base plate 24, that is, the + X side. Thereby, the cover portion 71 closes the gap between the back cover 60 and the side plate portion 212 of the outer box body 21. The cover portion 71 is connected to the connecting portion 72, as shown in FIG. 8.

連結部７２は、実施の形態１で説明した連結部材４０と同様の、鉛直板７２１と、水平板７２２と、を備える。連結部７２は、１枚の板金がプレス加工されることによりカバー部７１と共に形成されている。このため、連結部７２は、カバー部７１と一体である。詳細には、水平板７２２の背面側の端部が、カバー部７１の背面部７１１の下端と連続している。 The connecting portion 72 includes a vertical plate 721 and a horizontal plate 722 similar to the connecting member 40 described in the first embodiment. The connecting portion 72 is formed together with the cover portion 71 by pressing one sheet metal. Therefore, the connecting portion 72 is integral with the cover portion 71. Specifically, the rear end of the horizontal plate 722 is continuous with the lower end of the rear surface 711 of the cover 71.

図示しないが、鉛直板７２１は、補強部材３０に固定される。また、水平板７２２は、台板２４に固定される。これにより、連結部７２は、補強部材３０と台板２４を連結する。 Although not shown, the vertical plate 721 is fixed to the reinforcing member 30. The horizontal plate 722 is fixed to the base plate 24. Thereby, the connecting portion 72 connects the reinforcing member 30 and the base plate 24.

なお、側面カバー７０Ｒの作用は、カバー部７１が機械室２００の側方を塞ぐことを除いて、実施の形態１の連結部材４０と同様である。このため、説明を省略する。 The operation of the side cover 70R is the same as that of the connecting member 40 of the first embodiment, except that the cover portion 71 closes the side of the machine room 200. Therefore, the description is omitted.

以上のように、実施の形態３に係る冷蔵庫１Ｃでは、機械室２００の側面カバー７０Ｒ、７０Ｌが、実施の形態１と同じ構成の連結部７２を備える。このため、冷蔵庫１Ｃでは、機械室２００の開口を塞ぐだけでなく、台板２４が補強され、その結果、台板２４が変形しにくい。 As described above, in the refrigerator 1C according to the third embodiment, the side covers 70R and 70L of the machine room 200 include the connecting portion 72 having the same configuration as that of the first embodiment. Therefore, in the refrigerator 1C, not only is the opening of the machine room 200 closed, but the base plate 24 is reinforced, and as a result, the base plate 24 is less likely to deform.

以上、本発明の実施の形態を説明したが、本発明は上記の実施の形態に限定されるものではない。例えば、上記の実施の形態では、底板２３の背面部２３Ｂが機械室２００の天井を形成している。しかし、本発明はこれに限定されない。本発明では、外箱本体２１が、冷蔵室１００の下側に形成され、背面側かつ底側が開口した機械室２００を備えていればよい。そして、機械室２００が天井を有していればよい。従って、機械室２００の天井が、底板２３以外の部材で形成されてもよい。例えば、機械室２００の天井が、専用の天井板によって形成されてもよい。なお、外箱本体２１は、外郭と称されてもよい。 Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments. For example, in the above embodiment, the back surface portion 23B of the bottom plate 23 forms the ceiling of the machine room 200. However, the present invention is not limited to this. In the present invention, the outer box body 21 may be provided with the machine room 200 formed on the lower side of the refrigerating room 100 and having an opening on the back side and the bottom side. The machine room 200 only needs to have a ceiling. Therefore, the ceiling of the machine room 200 may be formed of a member other than the bottom plate 23. For example, the ceiling of the machine room 200 may be formed by a dedicated ceiling plate. The outer box body 21 may be referred to as an outer shell.

また、実施の形態１−３では、外箱本体２１の側板部２１２、２１３が機械室２００の側壁を形成している。しかし、本発明では、機械室２００が側壁を有する限りにおいて、側壁を形成する部品は任意である。例えば、外箱本体２１の側板部２１２、２１３の内側に、補強板が設置され、その補強板が機械室２００の側壁を形成してもよい。 Further, in Embodiments 1-3, the side plate portions 212 and 213 of the outer box body 21 form the side walls of the machine room 200. However, in the present invention, as long as the machine room 200 has side walls, the parts forming the side walls are arbitrary. For example, a reinforcing plate may be installed inside the side plate portions 212 and 213 of the outer box body 21, and the reinforcing plate may form the side wall of the machine room 200.

実施の形態１−３では、連結部材４０、５０Ｒ、５０Ｌ、連結部７２の鉛直板４１、５１、７２１がネジによって補強部材３０の鉛直部３１に締結されている。また、水平板４２、５２、７２２は、ネジによって台板２４に締結されている。しかし、本発明はこれに限定されない。本発明では、鉛直板４１、５１、７２１が補強部材３０の鉛直部３１に固定され、水平板４２、５２、７２２が台板２４に固定される限りにおいて、その固定方法は任意である。このため、ネジによる締結以外の固定方法であってもよい。例えば、鉛直板４１、５１、７２１が補強部材３０の鉛直部３１に溶接されてもよいし、水平板４２、５２、７２２が台板２４に溶接されてもよい。いずれか一方の固定方法が溶接によるものであってもよい。ほか、接着による固定であってもよい。なお、本明細書では、連結部７２を連結部材ともいう。 In Embodiment 1-3, the connecting members 40, 50R, 50L and the vertical plates 41, 51, 721 of the connecting portion 72 are fastened to the vertical portion 31 of the reinforcing member 30 by screws. The horizontal plates 42, 52, 722 are fastened to the base plate 24 with screws. However, the present invention is not limited to this. In the present invention, the fixing method is arbitrary as long as the vertical plates 41, 51 and 721 are fixed to the vertical portion 31 of the reinforcing member 30 and the horizontal plates 42, 52 and 722 are fixed to the base plate 24. Therefore, a fixing method other than the fastening with screws may be used. For example, the vertical plates 41, 51, 721 may be welded to the vertical portion 31 of the reinforcing member 30, and the horizontal plates 42, 52, 722 may be welded to the base plate 24. Either one of the fixing methods may be welding. Alternatively, it may be fixed by adhesion. In this specification, the connecting portion 72 is also referred to as a connecting member.

また、本発明では、連結部材４０、５０Ｒ、５０Ｌ、連結部７２が補強部材３０の鉛直部３１の背面に当接すると共に鉛直部３１に固定され、かつ連結部材４０、５０Ｒ、５０Ｌ、連結部７２が台板２４の上面に沿って背面側に延在すると共に、台板２４に固定されていればよい。従って、この限りにおいて、連結部材４０、５０Ｒ、５０Ｌ、連結部７２の形状も任意である。例えば、鉛直板４１、５１、７２１と水平板４２、５２、７２２は、四角柱、四角筒の形状であってもよい。実施の形態３で説明した連結部７２が斜材５３を有する場合、斜材５３は、四角柱、四角筒の形状であってもよい。また、連結部材４０、５０Ｒ、５０Ｌ、連結部７２は、側面視、すなわちＸ方向視で、直角２等辺三角形状のブロックであってもよい。この場合、そのブロックは、直角を形成する２つの辺のうち、一方の辺を補強部材３０の鉛直部３１に、他方の辺を台板２４に向けて配置されるとよい。そして、補強部材３０の鉛直部３１と台板２４に固定されるとよい。なお、本明細書では、鉛直板４１、５１、７２１と水平板４２、５２、７２２が補強部材３０の鉛直部３１と台板２４に固定されることから、鉛直板４１、５１、７２１と水平板４２、５２、７２２のことを第１固定部、第２固定部ともいう。 Further, in the present invention, the connecting members 40, 50R, 50L and the connecting portion 72 abut on the back surface of the vertical portion 31 of the reinforcing member 30 and are fixed to the vertical portion 31, and the connecting members 40, 50R, 50L and the connecting portion 72. Need only extend to the back side along the upper surface of the base plate 24 and be fixed to the base plate 24. Therefore, as long as this is the case, the shapes of the connecting members 40, 50R, 50L and the connecting portion 72 are arbitrary. For example, the vertical plates 41, 51, 721 and the horizontal plates 42, 52, 722 may be in the shape of a square pole or a square cylinder. When the connecting portion 72 described in the third embodiment has the diagonal member 53, the diagonal member 53 may be in the shape of a square pole or a square cylinder. Further, the connecting members 40, 50R, 50L and the connecting portion 72 may be blocks having an isosceles right triangle shape in a side view, that is, an X direction view. In this case, the block is preferably arranged with one of the two sides forming a right angle facing the vertical portion 31 of the reinforcing member 30 and the other side facing the base plate 24. Then, the vertical portion 31 of the reinforcing member 30 and the base plate 24 may be fixed. In the present specification, since the vertical plates 41, 51, 721 and the horizontal plates 42, 52, 722 are fixed to the vertical portion 31 of the reinforcing member 30 and the base plate 24, they are horizontal to the vertical plates 41, 51, 721. The plates 42, 52 and 722 are also referred to as a first fixing portion and a second fixing portion.

実施の形態１−３では、背面部材２２に充填された断熱材が硬質ウレタンフォームである。しかし、本発明では、背面部材２２に断熱材が収容されていればよく、その限りにおいて、断熱材の材料、構造は任意である。例えば、断熱材は、グラスウール、ポリスチレンフォームであってもよい。 In Embodiment 1-3, the heat insulating material with which back member 22 is filled is a hard urethane foam. However, in the present invention, the heat insulating material may be housed in the back member 22, and the material and structure of the heat insulating material are arbitrary as long as the heat insulating material is contained. For example, the insulating material may be glass wool, polystyrene foam.

なお、本発明は冷蔵庫全般に適用可能である。実施の形態１−３では、冷却器が内箱１０に設けられた直冷式の冷蔵庫について説明しているが、本発明は間接冷却方式の冷蔵庫にも適用可能である。また、内箱１０の替わりに内壁部材を有する冷蔵庫にも適用可能である。 The present invention is applicable to refrigerators in general. Although the first to third embodiments describe the direct cooling type refrigerator in which the cooler is provided in the inner box 10, the present invention is also applicable to an indirect cooling type refrigerator. Further, it is also applicable to a refrigerator having an inner wall member instead of the inner box 10.
