Abstract
Description
この発明は、冷蔵庫に関し、特に、外箱の剛性を高めるのに好適なものである。 The present invention relates to a refrigerator, and is particularly suitable for increasing the rigidity of an outer box.
近年、家庭用冷蔵庫は大型化が進んでおり、これに対応するためには、冷蔵庫の外郭を構成する断熱箱体の剛性を高めることが要求される。この要求に応えるべく、例えば、特許文献１では次のような提案がなされている。 In recent years, the size of household refrigerators has been increasing, and in order to cope with this, it is required to increase the rigidity of the heat insulating box constituting the outer shell of the refrigerator. In order to meet this requirement, for example, Patent Document 1 proposes the following.
即ち、特許文献１に記載の冷蔵庫では、底板を補強用アングルに補強板を用いずにネジ止めできるようにすると共に、底板のネジ止めを容易にするために、外箱の左右両側下部に補強用アングルを設け、この補強用アングルに位置決め部を切り起こし形成する。これに対して、底板に三角突起状の係合部を形成し、この係合部を位置決め部に係合させることにより、底板を補強用アングルに対して位置決めする。更に、補強用アングルの内側に切り起こし形成したネジ止め片に底板を挟み込み、このネジ止め片に底板をねじ止めする。 That is, in the refrigerator described in Patent Document 1, the bottom plate can be screwed to the reinforcing angle without using the reinforcing plate, and the bottom plate is reinforced at the left and right side lower portions to facilitate screwing of the bottom plate. A working angle is provided, and a positioning part is cut and formed on the reinforcing angle. In contrast, the bottom plate is positioned with respect to the reinforcing angle by forming a triangular protrusion-like engagement portion on the bottom plate and engaging the engagement portion with the positioning portion. Further, the bottom plate is sandwiched between screwing pieces formed by cutting and raising inside the reinforcing angle, and the bottom plate is screwed to the screwing pieces.
しかしながら、特許文献１では、依然として補強用アングルと底板の構造は複雑であり、その製造コストも掛かるため、改善の余地はまだ残されている。特に、特許文献１では、外箱の側板と補強用アングルとを冷蔵庫の前面側で固定するために、圧着や螺子締結などの固定作業を追加で行わなければならず、製造コストが増加するという問題点があった。 However, in Patent Document 1, the structure of the reinforcing angle and the bottom plate is still complicated, and the manufacturing cost is high, so there is still room for improvement. In particular, in Patent Document 1, in order to fix the side plate of the outer box and the reinforcing angle on the front side of the refrigerator, additional fixing work such as crimping and screw fastening must be performed, which increases the manufacturing cost. There was a problem.
この発明は、上記のような問題点を解決するためになされたもので、その第１の目的は、剛性を高めた外箱を安価に提供できるようにすることにある。また、本発明の第２の目的は、外箱の剛性を高めるにあたって、冷蔵庫の容積を減らさないようにすることにある。 The present invention has been made to solve the above-described problems, and a first object of the present invention is to provide an outer box with increased rigidity at a low cost. The second object of the present invention is to prevent the volume of the refrigerator from being reduced when increasing the rigidity of the outer box.
上記目的を達成するために、本発明は、天板と両側板とを有する外箱と、前記両側板の正面側の下端に位置して、前記両側板を繋ぐように設けられた前板と、前記両側板のそれぞれの下辺に沿って設けられ、前記外箱を補強する補強部材と、冷媒が流れる放熱パイプと、を備えた冷蔵庫において、前記外箱の正面側の下角部の位置において、少なくとも前記前板と前記補強部材とを螺子で固定し、前記放熱パイプを前記側板および前記前板に沿うようにして前記外箱の内側に配設し、前記放熱パイプを少なくとも３箇所折り曲げて屈曲部を形成し、当該屈曲部によって前記螺子との干渉を避ける構成としたことを特徴としている。 To achieve the above object, the present invention includes an outer box having a top plate and both side plates, and a front plate provided at the lower end of the front side of the both side plates so as to connect the both side plates. A refrigerator provided with a reinforcing member that reinforces the outer box, and a heat-dissipating pipe through which a refrigerant flows, provided along the lower side of each of the both side plates, at the position of the lower corner on the front side of the outer box, At least the front plate and the reinforcing member are fixed with screws, the heat radiating pipe is disposed inside the outer box along the side plate and the front plate, and the heat radiating pipe is bent and bent at at least three places. A portion is formed, and the bent portion avoids interference with the screw.

上記のように構成された本発明によれば、剛性を高めた外箱を安価に提供することができる。また、本発明によれば、外箱の剛性を高めるにあたって、冷蔵庫の容積を減らさないようにすることもできる。 According to the present invention configured as described above, an outer box with increased rigidity can be provided at a low cost. Further, according to the present invention, it is possible to prevent the volume of the refrigerator from being reduced when increasing the rigidity of the outer box.
以下、本発明の実施の形態例に係る冷蔵庫について、図１〜図１４を用いて説明する。図１に示す冷蔵庫は、近年主流になっている冷蔵室が観音開きの大型冷蔵庫である。この冷蔵庫１００は、外箱１、内箱（図示せず）及びそれらの間に充填された断熱材（図示せず）で構成された断熱箱体の上段に、例えば観音開きの冷蔵室扉２００で前面が開閉される冷蔵室を配置し、中段に、例えば引出式の製氷室扉３００と上段冷凍室扉４００と下段冷凍室扉５００を有する冷凍室を配置し、下段に、例えば引出式の野菜室扉６００を有する野菜室を配置して構成されている。 Hereinafter, the refrigerator which concerns on the embodiment of this invention is demonstrated using FIGS. The refrigerator shown in FIG. 1 is a large-sized refrigerator with a double-sided refrigerator compartment that has become mainstream in recent years. The refrigerator 100 has, for example, a refrigerating room door 200 with a double door opening on an upper side of an insulating box composed of an outer box 1, an inner box (not shown), and a heat insulating material (not shown) filled therebetween. A refrigerator compartment whose front is opened and closed is arranged, a freezer room having, for example, a drawer type ice making room door 300, an upper stage freezer room door 400 and a lower stage freezer room door 500 is arranged in the middle stage, and a drawer type vegetable, for example, is arranged in the lower stage. A vegetable room having a room door 600 is arranged.
外箱１は、鋼板をプレス成形して構成されるものであり、図２および図４に示すように、２つの側板１ａ，１ｂと、これら両側板１ａ，１ｂと連続する天板１ｃとを備え、前面、背面及び底面が開放したコ字形状を成している。そして、側板１ｂの２つの長辺のうち正面側の長辺には、フランジ部１ｅが長辺に沿って一様に設けられている。なお、このフランジ部１ｅは、側板１ｂの長辺から内側に向かって略直角に折れ曲がるようにして設けられている。そして、フランジ部１ｅの下端部には、後述する固定用ネジ８が挿入される孔３０ｂと、本発明の螺子に相当する補強用ネジ９が挿入される開口３１ｂが設けられている（図８参照）。 The outer box 1 is formed by press-molding a steel plate. As shown in FIGS. 2 and 4, two side plates 1a and 1b and a top plate 1c continuous with these side plates 1a and 1b are provided. It has a U shape with the front, back and bottom open. And the flange part 1e is uniformly provided in the long side of the front side among the two long sides of the side plate 1b along the long side. The flange portion 1e is provided so as to be bent at a substantially right angle from the long side of the side plate 1b toward the inside. A lower end portion of the flange portion 1e is provided with a hole 30b into which a fixing screw 8 described later is inserted, and an opening 31b into which a reinforcing screw 9 corresponding to the screw of the present invention is inserted (FIG. 8). reference).
この開口３１ｂは、補強用ネジ９の頭部が開口３１ｂ内に没入する程度の外形を有して形成されている。そのため、開口３１ｂに補強用ネジ９を挿入すると、補強用ネジ９の頭部がフランジ部１ｅの表面から突出することがない。これにより、補強用ネジ９の頭部が突出して外観を損ねてしまうといったことがない上、野菜室扉６００のパッキンに隙間が生じるといった不具合も生じない。さらには、補強用ネジ９の先端部は外箱１の内部にあるので、ユーザーが補強用ネジ９の先端部を触って怪我をするといった心配もない。なお、側板１ａにものフランジ部１ｄ、孔（図示せず）、開口（図示せず）が設けられているが、その構成は側板１ｂと同様であるため、ここでの説明は省略する。 The opening 31b is formed with an outer shape such that the head of the reinforcing screw 9 is immersed in the opening 31b. For this reason, when the reinforcing screw 9 is inserted into the opening 31b, the head of the reinforcing screw 9 does not protrude from the surface of the flange portion 1e. As a result, the head of the reinforcing screw 9 does not protrude and the appearance is not impaired, and a problem that a gap occurs in the packing of the vegetable compartment door 600 does not occur. Furthermore, since the tip end portion of the reinforcing screw 9 is inside the outer box 1, there is no worry that the user touches the tip end portion of the reinforcing screw 9 to get injured. In addition, although the flange part 1d, the hole (not shown), and opening (not shown) are provided in the side plate 1a, since the structure is the same as that of the side plate 1b, description here is abbreviate | omitted.
この外箱１には、図２および図３に示すように、一対の補強部材２ａ，２ｂ、前板３、および、放熱パイプ４が設けられている。前板３は、例えば厚さ１ｍｍの鋼板を成形したものであり、図６に示すように、その両端に当接部１５ａ，１５ｂが形成されている。当接部１５ｂには、固定用ネジ８と締結する雌ネジ穴１７ｂと、補強用ネジ９の挿入を許容する程度の直径を有する挿入孔１６ｂとが、上下方向にやや間隔を空けて設けられている。この前板３は、図２および図３に示すように、一端に形成されている当接部１５ｂがフランジ部１ｅの裏面と当接し、他端に形成されている当接部１５ａがフランジ部１ｄの裏面と当接した状態で、外箱１の下端の位置に、両側板１ａ，１ｂを繋ぐようにして取り付けられている。そして、前板３が取り付けられた状態の外箱１を正面から見ると、両側板１ａ，１ｂと、天板１ｃと、前板３とにより、矩形枠が形成されるようになっている。なお、前板３の当接部１５ａにも、当接部１５ｂと同様に雌ネジ穴１７ａおよび挿入孔１６ａが設けられている。 As shown in FIGS. 2 and 3, the outer box 1 is provided with a pair of reinforcing members 2 a and 2 b, a front plate 3, and a heat radiating pipe 4. The front plate 3 is formed, for example, of a steel plate having a thickness of 1 mm, and contact portions 15a and 15b are formed at both ends thereof as shown in FIG. The contact portion 15b is provided with a female screw hole 17b that is fastened to the fixing screw 8 and an insertion hole 16b that has a diameter that allows insertion of the reinforcing screw 9 with a slight gap in the vertical direction. ing. As shown in FIGS. 2 and 3, the front plate 3 has a contact portion 15b formed at one end in contact with the back surface of the flange portion 1e and a contact portion 15a formed at the other end in the flange portion. The two side plates 1a and 1b are attached to the position of the lower end of the outer box 1 while being in contact with the back surface of 1d. When the outer box 1 with the front plate 3 attached is viewed from the front, the side plates 1a and 1b, the top plate 1c, and the front plate 3 form a rectangular frame. In addition, the female screw hole 17a and the insertion hole 16a are provided also in the contact part 15a of the front board 3 like the contact part 15b.
次に、補強部材２ａは、例えば、厚さ１．２ｍｍの鋼板を成形したものであり、図５に示すように、細長いアングル部材１０ａの前端に立ち上がり部１２ａを有し、後端にストッパ部材１１ａを有していると共に、全体として略Ｌ字形状を成すように構成されるものである。立ち上がり部１２ａには、後述する固定用ネジ８の先端部が入り込むための逃げ孔１４ａと、本発明の螺子穴に相当し、後述する補強用ネジ９と締結する雌ネジ穴１３ａとが、上下方向にやや間隔を空けて設けられている。補強部材２ａを側板１ａの下辺に沿って外箱１の背面側から正面側へスライドするようにして取り付けると、ストッパ部材１１ａが側板１ａの背面側の長辺と当接してスライド方向の位置決めがされると共に、立ち上がり部１２ａが前板の当接部１５ａと当接した状態となる。なお、補強部材２ｂについてもその構成は同じであるため、ここでの説明は省略する。 Next, the reinforcing member 2a is formed by, for example, a steel plate having a thickness of 1.2 mm. As shown in FIG. 5, the elongate angle member 10a has a rising portion 12a at the front end and a stopper member at the rear end. 11a, and is configured to have a substantially L shape as a whole. The rising portion 12a is provided with a relief hole 14a for receiving a distal end portion of a fixing screw 8 to be described later, and a female screw hole 13a that corresponds to a screw hole of the present invention and is fastened to a reinforcing screw 9 to be described later. It is provided with some space in the direction. When the reinforcing member 2a is attached so as to slide from the back side of the outer box 1 to the front side along the lower side of the side plate 1a, the stopper member 11a comes into contact with the long side on the back side of the side plate 1a and positioning in the sliding direction is performed. At the same time, the rising portion 12a comes into contact with the contact portion 15a of the front plate. In addition, since the structure is the same also about the reinforcement member 2b, description here is abbreviate | omitted.
また、放熱パイプ４は、例えば銅製のチューブを略同一平面上で何か所も折り返すようにＵ字状に折り曲げて構成されており、図７に示すように、左側に３つの垂直部２６ａ，２６ｂ，２６ｃと、右側に１つの垂直部２６ｄと、下側に水平部２７とを有している。この放熱パイプ４は、外箱１の内側の所定の位置に取り付けると、垂直部２６ａ，２６ｂ，２６ｃが側板１ｂのフランジ部１ｅに沿い、水平部２７が前板３に沿い、かつ、垂直部２６ｄが側板１ａのフランジ部１ｄに沿うようになっている。なお、放熱パイプ４内を冷媒が流れることにより、外気との熱交換が行われて、冷蔵庫内が冷却されることになるが、この点については公知であるため、ここでの説明は省略する。 Further, the heat radiating pipe 4 is formed by bending a copper tube, for example, in a U shape so as to be folded back at some points on a substantially same plane, and as shown in FIG. 26b, 26c, one vertical portion 26d on the right side, and a horizontal portion 27 on the lower side. When the heat radiating pipe 4 is attached to a predetermined position inside the outer box 1, the vertical portions 26a, 26b, and 26c are along the flange portion 1e of the side plate 1b, the horizontal portion 27 is along the front plate 3, and the vertical portion. 26d is along the flange part 1d of the side plate 1a. In addition, although a refrigerant | coolant flows through the inside of the heat radiating pipe 4, heat exchange with external air will be performed and the inside of a refrigerator will be cooled, but since this is well-known, description here is abbreviate | omitted. .
さらに、放熱パイプ４は、その左下角部に、図７に示すように、折れ曲がり箇所２４ａ，２４ｂ，２４ｃの３箇所で折り曲げられて略Ｕ字状に形成された屈曲部２５を有している。この屈曲部２５は、補強用ネジ９との干渉を回避するため、図３および図８に示すように、放熱パイプ４を外箱１に取り付けた状態において背面側に折れ曲がるように構成されているが、外箱１の正面側から見ると、図９に示すように、側板１ｂのフランジ部１ｅと前板３の裏面側に隠れて見えない。そして、放熱パイプ４を外箱１の内側の所定の位置に取り付けると、補強用ネジ９が屈曲部２５の内側に位置するよう構成されている（図８参照）。このようにして、補強用ネジ９と放熱パイプ４との干渉が回避されているのである。 Furthermore, the heat radiating pipe 4 has, at the lower left corner, a bent portion 25 that is bent at three bent portions 24a, 24b, and 24c and formed in a substantially U shape, as shown in FIG. . In order to avoid interference with the reinforcing screw 9, the bent portion 25 is configured to bend to the back side when the heat radiating pipe 4 is attached to the outer box 1, as shown in FIGS. 3 and 8. However, when viewed from the front side of the outer box 1, it is hidden behind the flange portion 1e of the side plate 1b and the back side of the front plate 3 as shown in FIG. When the heat radiating pipe 4 is attached to a predetermined position inside the outer box 1, the reinforcing screw 9 is configured to be located inside the bent portion 25 (see FIG. 8). In this way, interference between the reinforcing screw 9 and the heat radiating pipe 4 is avoided.
これらの各種部材２ａ，２ｂ，３，４の外箱１への組み込み作業は、以下の手順で行われる。まず、プレス加工されたコ字形の外箱１を、開放した前面を下になるように寝かせ、前板３の両端に形成された当接部１５ａ，１５ｂを外箱１のフランジ部１ｄ，１ｅに背面側から当接させる。次に、外箱１の前面側から、固定用ネジ８をフランジ部１ｅに設けられた孔３０ｂに挿入し、前板３の雌ネジ穴１７ｂへとねじ込んで前板３を側板１ｂと固定する。側板１ａと前板３との固定も同様にして行う。 The operation of assembling these various members 2a, 2b, 3 and 4 into the outer box 1 is performed according to the following procedure. First, the U-shaped outer box 1 that has been pressed is laid down so that the opened front face faces down, and the contact portions 15a and 15b formed at both ends of the front plate 3 are flanged portions 1d and 1e of the outer box 1, respectively. It is made to contact from the back side. Next, the fixing screw 8 is inserted into the hole 30b provided in the flange portion 1e from the front side of the outer box 1, and screwed into the female screw hole 17b of the front plate 3 to fix the front plate 3 to the side plate 1b. . The side plate 1a and the front plate 3 are fixed in the same manner.
次に、補強部材２ａ、２ｂを外箱１の両側板１ａ，１ｂの下辺に沿って挿入し、補強部材２ａ，２ｂの立ち上がり部１２ａ，１２ｂを前板３の当接部１５ａ，１５ｂに当接させる。このとき、固定用ネジ８の先端部が、立ち上がり部１２ａ，１２ｂの逃げ孔１４ａ，１４ｂにそれぞれ挿入されているかに留意する。次に、外箱１の前面側から、補強用ネジ９をフランジ部１ｅに設けられた開口３１ｂから挿入し、補強部材２ｂの前板３の雌ネジ穴１３ｂへとねじ込んで前板３と補強部材２ｂと固定する。前板３と補強部材２ａとの固定も同様にして行う。これで、外箱１への各種部材２ａ，２ｂ，３，４の取り付けは完成する。 Next, the reinforcing members 2a and 2b are inserted along the lower sides of the side plates 1a and 1b of the outer box 1, and the rising portions 12a and 12b of the reinforcing members 2a and 2b are brought into contact with the contact portions 15a and 15b of the front plate 3, respectively. Make contact. At this time, attention should be paid to whether or not the distal ends of the fixing screws 8 are respectively inserted into the escape holes 14a and 14b of the rising portions 12a and 12b. Next, the reinforcing screw 9 is inserted from the front side of the outer box 1 through the opening 31b provided in the flange portion 1e and screwed into the female screw hole 13b of the front plate 3 of the reinforcing member 2b to reinforce the front plate 3. It fixes with the member 2b. The front plate 3 and the reinforcing member 2a are fixed in the same manner. Thus, the attachment of the various members 2a, 2b, 3 and 4 to the outer box 1 is completed.
次に、外箱１の剛性を高めることと野菜室扉６００により仕切られた野菜室の容積Ｖとの関係について図９〜図１３を参照しながら説明する。図１０は、従来の外箱構造を採用した場合の野菜室の容積を示している。図１０に示すように、前板３と側板１ｂを固定用ネジ８のみで固定した従来の構造では、放熱パイプ４をフランジ部１ｅと前板３の裏面側に沿って折り曲げながら配置する際に、補強用ネジ９と干渉することはないので、野菜室の容積をＶだけ確保することができる。 Next, the relationship between increasing the rigidity of the outer box 1 and the volume V of the vegetable compartment partitioned by the vegetable compartment door 600 will be described with reference to FIGS. FIG. 10 shows the volume of the vegetable compartment when the conventional outer box structure is adopted. As shown in FIG. 10, in the conventional structure in which the front plate 3 and the side plate 1b are fixed only by the fixing screws 8, the heat radiating pipe 4 is arranged while being bent along the flange portion 1e and the back side of the front plate 3. Since there is no interference with the reinforcing screw 9, the volume of the vegetable compartment can be secured by V.
ところが、放熱パイプ４に本実施形態のような屈曲部２５を設けることがないまま、外箱１の剛性を高めるために補強部材２ｂと前板３とを補強用ネジ９で固定すると、図１１に示すように、放熱パイプ４が補強用ネジ９と干渉してしまう。そこで、図１２に示すように、放熱パイプ４を図１１よりも大きなアール（Ｒ）で折り曲げて、補強用ネジ９との干渉を回避するようにすることが考えられる。 However, when the reinforcing member 2b and the front plate 3 are fixed with the reinforcing screw 9 in order to increase the rigidity of the outer case 1 without providing the bent portion 25 as in the present embodiment on the heat radiating pipe 4, FIG. As shown in FIG. 2, the heat radiating pipe 4 interferes with the reinforcing screw 9. Then, as shown in FIG. 12, it is possible to bend the heat radiating pipe 4 with a radius (R) larger than that in FIG. 11 to avoid interference with the reinforcing screw 9.
しかし、放熱パイプ４の折れ曲がり部分のアールが大きくなると、放熱パイプ４を高さｈの前板３で覆い隠すことができなくなるため、図１２のように前板３の端部に放熱パイプ４を隠すための三角片（高さｈ０）を設けなければならなくなる。そうすると、野菜室の容積は、三角片の部分に相当する容積Ｖ０だけ減少して、Ｖ−Ｖ０となる。これでは、せっかく外箱１の剛性を高めても、野菜室の容積が従来のものより減少するので好ましいとは言い難い。また、図１３のように、前板３を高さｈ１だけ一様に高くして放熱パイプ４の折れ曲がり部分を隠すようにすると、高さｈ１の分だけ野菜室の容積は減少してＶ−Ｖ１となる。 However, if the radius of the bent portion of the heat radiating pipe 4 becomes large, it becomes impossible to cover the heat radiating pipe 4 with the front plate 3 having a height h, so that the heat radiating pipe 4 is attached to the end of the front plate 3 as shown in FIG. It is necessary to provide a triangular piece (height h 0 ) to hide. Then, the volume of the vegetable room is reduced by a volume V 0 corresponding to the triangular piece portion, and becomes V−V 0 . In this case, even if the rigidity of the outer box 1 is increased, it is difficult to say that it is preferable because the volume of the vegetable compartment is reduced as compared with the conventional one. Further, as shown in FIG. 13, when the front plate 3 by the height h 1 uniformly high to hide the bent portion of the radiating pipe 4, the amount corresponding to the height h 1 volume of vegetable compartment is reduced the V-V 1.
このように、単に補強部材２ｂと前板３とを補強用ネジ９で固定して外箱１の剛性を高めようとすると、野菜室の容積は減少してしまう。ところが、本実施形態では、図９に示すように、放熱パイプ４の屈曲部２５を背面側にＵ字状に折り曲げているので、放熱パイプ４と補強用ネジ９との干渉を回避しつつ、野菜室の容積をＶだけ確保することができる。つまり、本実施形態では、野菜室の容積を減らすことなく、外箱１の剛性を高めることができるのである。 Thus, if the reinforcing member 2b and the front plate 3 are simply fixed by the reinforcing screws 9 to increase the rigidity of the outer box 1, the volume of the vegetable compartment decreases. However, in this embodiment, as shown in FIG. 9, the bent portion 25 of the heat radiating pipe 4 is bent in a U shape on the back side, so that interference between the heat radiating pipe 4 and the reinforcing screw 9 is avoided. The volume of the vegetable room can be secured by V. That is, in this embodiment, the rigidity of the outer box 1 can be increased without reducing the volume of the vegetable compartment.
そして、本実施形態によれば、上述したように外箱１の剛性を高めることができるため、図１４に示すように外箱１全体を平行四辺形のように変形させる外力が加わった場合であっても、図１４のような観音開き扉に段差が発生するという問題が発生することは皆無である。このことは、近年大型冷蔵庫で主流となりつつある観音開き型冷蔵庫において、本発明の実施の形態例に係る冷蔵庫が好適であることを意味する。しかも、補強部材２ａ，２ｂと前板３とを補強用ネジ９で固定して、放熱パイプ４に屈曲部２５を設けるだけで良いので、強固で歪みの少ない外箱１を安価に提供することが可能である。 And according to this embodiment, since the rigidity of the outer case 1 can be improved as described above, when an external force is applied to deform the entire outer case 1 like a parallelogram as shown in FIG. Even if it exists, the problem that a level | step difference will generate | occur | produce in a double door as shown in FIG. 14 will never generate | occur | produce. This means that the refrigerator according to the embodiment of the present invention is suitable for the double door type refrigerator that is becoming mainstream in large refrigerators in recent years. Moreover, it is only necessary to fix the reinforcing members 2a, 2b and the front plate 3 with the reinforcing screw 9 and provide the bent portion 25 on the heat radiating pipe 4, so that the outer box 1 which is strong and less distorted can be provided at low cost. Is possible.
なお、上記した実施の形態例では、補強用ネジ９の頭部がフランジ部１ｄ，１ｅから突出しないために開口３１ａ，３１ｂを設けた構成としたが、この構成に代えて、図１５に示すように、補強用ネジ９の頭部がフランジ部１ｄ，１ｅの表面から突出しない程度の深さｄ（即ち、深さｄは、補強用ネジ９の頭部の高さ以上である）だけ窪んだ段差部５０を設け、この段差部５０の略中央で、挿入孔１６ａ，１６ｂを臨む位置に、補強用ネジ９を挿入可能な程度の貫通孔５１を設けるようにしても良い。この構成であっても、開口３１ａ，３１ｂと同様の効果、即ち、補強用ネジ９の頭部が突出して外観を損ねてしまうこと、野菜室扉６００のパッキンに隙間が生じること、および、ユーザーが補強用ネジ９の先端部を触って怪我をすること、を防止できるといった効果を奏する。 In the above-described embodiment, the openings 31a and 31b are provided so that the head of the reinforcing screw 9 does not protrude from the flange portions 1d and 1e. Thus, the depth d (that is, the depth d is not less than the height of the head of the reinforcing screw 9) is recessed so that the head of the reinforcing screw 9 does not protrude from the surface of the flange portions 1d and 1e. A stepped portion 50 may be provided, and a through-hole 51 to the extent that the reinforcing screw 9 can be inserted may be provided at a position facing the insertion holes 16a and 16b at the approximate center of the stepped portion 50. Even with this configuration, the same effects as the openings 31a and 31b, that is, the head of the reinforcing screw 9 protrudes to impair the appearance, a gap occurs in the packing of the vegetable compartment door 600, and the user It is possible to prevent injuries by touching the tip of the reinforcing screw 9.
