Abstract
Description
本発明は冷蔵庫、特に冷蔵庫内の貯蔵室間を仕切る仕切板構成に関するものである。 The present invention relates to a refrigerator, and more particularly to a partition plate configuration for partitioning between storage rooms in the refrigerator.
一般に冷蔵庫は、冷蔵庫本体内に仕切板を設けて、冷蔵室、冷凍室、野菜室等の貯蔵室を形成しており、上記仕切板、例えば冷蔵室と冷凍室との間を仕切る仕切板は冷蔵庫本体を構成する内・外箱間と同様その内部に発泡ウレタンを充填して、断熱性を持たせた構成としてある（例えば、特許文献１参照）。 In general, a refrigerator is provided with a partition plate in the refrigerator body to form a storage room such as a refrigerator room, a freezer room, a vegetable room, and the partition plate, for example, a partition plate that partitions between the refrigerator room and the freezer room is It is set as the structure which filled the inside with foaming urethane like the inside / outer box which comprises a refrigerator main body, and gave heat insulation (for example, refer patent document 1).
図１１は上記特許文献１に記載された冷蔵庫を示し、この冷蔵庫は、冷蔵庫本体１００内を断熱仕切板１０１によって冷蔵室１０２と冷凍室１０３に仕切ってあり、その仕切板１０１はその上表面板１０１ａと下表面板１０１ｂとの間の中空部に発泡ウレタン１０４を充填して構成してある。 FIG. 11 shows the refrigerator described in the above-mentioned Patent Document 1. This refrigerator has a refrigerator main body 100 partitioned into a refrigerator compartment 102 and a freezer compartment 103 by a heat insulating partition plate 101, and the partition plate 101 is an upper surface plate. The hollow portion between 101a and the lower surface plate 101b is filled with foamed urethane 104.
上記特許文献１に記載された冷蔵庫は、断熱仕切板１０１内に発泡ウレタン１０４を充填しているので断熱性が高く、断熱仕切板１０１の板厚を薄くして冷蔵室１０２および冷凍室１０３の容積を減じることなく断熱性を確保することができる、という利点がある。特に冷蔵室１０２と冷凍室１０３とは冷却温度帯が大きく異なるので、これら両者間を仕切る仕切板に適用すれば効果が大きい。 The refrigerator described in Patent Document 1 has high heat insulating properties because the heat insulating partition plate 101 is filled with urethane foam 104, and the heat insulating partition plate 101 is made thin to reduce the thickness of the refrigerator compartment 102 and the freezer compartment 103. There is an advantage that heat insulation can be secured without reducing the volume. In particular, since the cooling temperature zone differs greatly between the refrigerator compartment 102 and the freezer compartment 103, the effect is great if applied to a partition plate that partitions the two.
しかしながら、上記断熱仕切板１０１の上表面板１０１ａおよび下表面板１０１ｂはポリプロピレン樹脂で構成されていて、発泡ウレタン１０４との密着性が悪く、場合によっては両者の間に剥離が生じ、断熱仕切板１０１の冷蔵室底面となる上表面板１０１ａの一部に浮き変形等が生じることがあった。 However, the upper surface plate 101a and the lower surface plate 101b of the heat insulation partition plate 101 are made of polypropylene resin and have poor adhesion to the urethane foam 104. In some cases, floating deformation or the like may occur in a part of the upper surface plate 101a serving as the bottom of the refrigerator compartment 101.
本発明はこのような点に鑑みてなしたもので、仕切板の表面板と発泡ウレタンとの間の剥離を抑制可能な冷蔵庫の提供を目的としたものである。 This invention is made in view of such a point, and it aims at provision of the refrigerator which can suppress peeling between the surface plate of a partition plate and urethane foam.
本発明は、上記目的を達成するため、仕切板はその内部の中空状部分に発泡ウレタンを充填して構成し、かつ、前記仕切板の表面板内面に鉤状部分を有するリブを設け、このリブを前記発泡ウレタン中に埋没させた構成としてある。 In order to achieve the above object, the partition plate is configured by filling urethane foam into a hollow portion inside the partition plate, and provided with a rib having a hook-shaped portion on the inner surface of the surface plate of the partition plate. The rib is embedded in the urethane foam.
これにより、仕切板の表面板内面に設けたリブの鉤状部分が発泡ウレタンと機械的に結合する形となり、仕切板の表面板が発泡ウレタンから剥離するのを抑制することができる。 As a result, the rib-shaped portions of the ribs provided on the inner surface of the surface plate of the partition plate are mechanically coupled to the urethane foam, and the surface plate of the partition plate can be prevented from being peeled off from the urethane foam.
本発明は、上記構成により、仕切板の表面板と発泡ウレタンとの剥離を抑制でき、表面板の浮き変形等がない品質の高い冷蔵庫とすることができる。 According to the above configuration, the present invention can suppress the separation between the surface plate of the partition plate and the urethane foam, and can provide a high-quality refrigerator that is free from floating deformation of the surface plate.
第１の発明は、冷蔵庫本体と、冷蔵庫本体内に複数の貯蔵室を形成する仕切板と、前記各貯蔵室を開閉する扉とを備え、前記仕切板はその内部の中空状部分に発泡ウレタンを充填して構成し、かつ、前記仕切板はその表面板内面に鉤状部分を有するリブを設け、このリブを前記発泡ウレタン中に埋没させた構成としてある。 1st invention is equipped with the refrigerator main body, the partition plate which forms a some storage chamber in a refrigerator main body, and the door which opens and closes each said storage chamber, and the said partition plate has urethane foam in the hollow-shaped part inside it. In addition, the partition plate is provided with a rib having a hook-like portion on the inner surface of the surface plate, and the rib is buried in the urethane foam.
これにより、仕切板の表面板内面に設けたリブの鉤状部分が発泡ウレタンと機械的に結合する形となり、仕切板の表面板が発泡ウレタンから剥離するのを抑制することができる。 As a result, the rib-shaped portions of the ribs provided on the inner surface of the surface plate of the partition plate are mechanically coupled to the urethane foam, and the surface plate of the partition plate can be prevented from being peeled off from the urethane foam.
第２の発明は、第１の発明において、前記冷蔵庫本体は内外箱間に発泡ウレタンを充填して構成するとともに、仕切板は前方左右に前記冷蔵庫本体の内外箱間に連通するウレタン充填口を設け、かつ、リブは橋形状として前記ウレタン充填口の開口面と交差するように配置した構成としてある。 According to a second invention, in the first invention, the refrigerator body is configured by filling urethane foam between the inner and outer boxes, and the partition plate has urethane filling ports communicating between the inner and outer boxes of the refrigerator body on the front left and right sides. The ribs are arranged in a bridge shape so as to intersect with the opening surface of the urethane filling port.
これにより、冷蔵庫本体への発泡ウレタン充填によって仕切板への発泡ウレタン充填が同時に行え、しかもウレタン充填口から仕切板内に流れ込む発泡ウレタンが仕切板の表面板内面と橋形状のリブとの間に確実に流れ込んで固化し、かつリブの発泡ウレタンと機械的に結合する鉤状部分が橋形状の両端二箇所となり、発泡ウレタンと橋形状のリブとの機械的結合が確実かつ強力なものとなる。したがって、冷蔵庫本体と仕切板との発泡ウレタン同時充填による生産性の向上を図りつつ、仕切板の表面板と発泡ウレタンとの剥離もより確実かつ強力に防止することができる。 As a result, urethane foam can be filled into the partition plate at the same time by filling the refrigerator body with foamed urethane, and the foamed urethane that flows into the partition plate from the urethane filling port is between the inner surface plate of the partition plate and the bridge-shaped rib. The hook-shaped part that flows into and solidifies reliably and mechanically bonds to the foamed urethane on the ribs is two places on both ends of the bridge shape, and the mechanical connection between the foamed urethane and the bridge-shaped ribs is reliable and strong. . Therefore, it is possible to more reliably and strongly prevent the separation between the surface plate of the partition plate and the urethane foam while improving the productivity by simultaneous filling of the foamed urethane with the refrigerator main body and the partition plate.
第３の発明は、第１または第２の発明において、前記リブは橋形状として仕切板の前部と後部にそれぞれ左右複数列設するとともに、前部に設けたリブの前後長は後部に設けたリブの前後長よりも長くした構成としてある。 According to a third invention, in the first or second invention, the ribs are provided in a plurality of rows on the front and rear sides of the partition plate as bridge shapes, and the longitudinal lengths of the ribs provided on the front portions are provided on the rear portions. The length is longer than the longitudinal length of the ribs.
これにより、仕切板前部における仕切板の表面板とリブとの機械的結合を強く広範囲にわたるものとすることができ、扉を開けたときに目につきやすい仕切板前部における剥離を効果的に防止することができる。 As a result, the mechanical connection between the surface plate and the rib of the partition plate at the front part of the partition plate can be made strong and extensive, and peeling at the front part of the partition plate that is easily noticeable when the door is opened is effectively prevented. be able to.
第４の発明は、第１〜第３の発明において、前記仕切板の左右両端部に扉を軸支するとともに、仕切板の表面板内面にはリブを左右方向に複数設け、このリブのうち前記扉軸支部近傍のリブは他のリブよりも仕切板の前端面寄り部分に設けた構成としてある。 According to a fourth invention, in the first to third inventions, a door is pivotally supported at both left and right ends of the partition plate, and a plurality of ribs are provided in the left-right direction on the inner surface of the surface plate of the partition plate. The rib in the vicinity of the door shaft support portion is provided in a portion closer to the front end face of the partition plate than the other ribs.
これにより、扉を軸支した仕切板の左右における仕切板の表面板とリブとの機械的結合
が扉軸支部に近い前端面側で行われるようになり、扉荷重が加わって表面板と発泡ウレタンとの剥離が生じやすい扉軸支部近傍の剥離をより効果的に抑制することができる。
As a result, the mechanical connection between the surface plate of the partition plate on the left and right of the partition plate that pivotally supports the door and the rib is performed on the front end surface side close to the door shaft support portion, and the door load is applied to the surface plate and the foam. It is possible to more effectively suppress peeling in the vicinity of the door shaft support portion that is likely to be peeled off from urethane.

ここで、上記冷蔵庫本体１は、既述したように冷蔵室５、切替室６及びこれに並設した製氷室７、冷凍室８、野菜室９等の複数の貯蔵室を有しているが、この各貯蔵室は仕切板２３、２４、２５により本体内を仕切ることによって形成している。 Here, as described above, the refrigerator main body 1 has a refrigerating room 5, a switching room 6, and a plurality of storage rooms such as an ice making room 7, a freezing room 8, and a vegetable room 9 arranged side by side. Each of the storage chambers is formed by partitioning the inside of the main body with partition plates 23, 24, and 25.
上記仕切板２３、２４、２５のうち、冷蔵室５と切替室６及びこれに並設した製氷室７との間を仕切る仕切板２３は、図７に示すように、冷気通路形成用のダクト部材２６、２７やダンパ部材２８を介して上表面板２３ａと下表面板２３ｂとを組み合わせ、この上表面板２３ａと下表面板２３ｂの前板２９および側板３０とダクト部材２６と間の中空部分に発泡ウレタン４を充填し構成してある。 Of the partition plates 23, 24, and 25, the partition plate 23 that partitions between the refrigerator compartment 5, the switching chamber 6, and the ice making chamber 7 provided in parallel therewith is, as shown in FIG.

The hinge member 15 is fixed with screws, and the doors 10 (10a, 10b) of the refrigerator compartment formed above the partition plate 23 are pivotally supported.
ここで、上記仕切板２３は、図８、図９に示すように、冷蔵室５の底面となる上表面板２３ａの内面にリブ３４が一体に設けてある。このリブ３４は、図６に示すように、仕切板２３の中空部分に充填した発泡ウレタン４中に埋没してこれと機械的に結合可能な鉤状形状、この実施の形態では両端に鉤状部分Ｘが存することになる橋形状に形成してある。 Here, as shown in FIGS. 8 and 9, the partition plate 23 is integrally provided with ribs 34 on the inner surface of the upper surface plate 23 a serving as the bottom surface of the refrigerator compartment 5. As shown in FIG. 6, the ribs 34 are hook-like shapes that can be buried in the urethane foam 4 filled in the hollow portion of the partition plate 23 and mechanically coupled thereto, and in this embodiment, hook-like shapes at both ends. Part X is formed in a bridge shape that will exist.
そして、上記リブ３４は、図８、図９から明らかなように、仕切板２３の前部と後部にそれぞれ左右複数個列設するとともに、前部に設けたリブ３４ａの前後長Ｌは後部に設けたリブ３４ｂの前後長ｌよりも長くした構成としてある。 As shown in FIGS. 8 and 9, the ribs 34 are arranged in a plurality on the left and right sides of the front and rear parts of the partition plate 23, and the longitudinal length L of the ribs 34a provided on the front part is on the rear part. The rib 34b is longer than the longitudinal length l of the provided rib 34b.
更に、前記リブ３４は上表面板２３ａの側板前方部分に設けたウレタン充填口３５の開口面と交差する前後方向に配置してある。 Further, the rib 34 is arranged in the front-rear direction intersecting the opening surface of the urethane filling port 35 provided in the front portion of the side plate of the upper surface plate 23a.
以上のように構成した冷蔵庫について、次にその作用効果について説明する。 Next, the effect of the refrigerator configured as described above will be described.
まず、仕切板２３へのウレタン充填を説明しておくと、この冷蔵庫では、図７に示す仕切板２３の上表面板２３ａと下表面板２３ｂとを組み合わせてあらかじめ中空状の仕切板２３を構成し、この仕切板２３を冷蔵庫本体１に組み込む。この状態で冷蔵庫本体１の内箱外箱間に発泡ウレタン４を充填する。 First, the urethane filling to the partition plate 23 will be described. In this refrigerator, the hollow partition plate 23 is configured in advance by combining the upper surface plate 23a and the lower surface plate 23b of the partition plate 23 shown in FIG. The partition plate 23 is incorporated into the refrigerator main body 1. In this state, foamed urethane 4 is filled between the inner and outer boxes of the refrigerator body 1.
これにより発泡ウレタン４が冷蔵庫本体１の内外箱間のウレタン放出口（図示せず）からウレタン充填口３５を介し仕切板２３の中空部分にも流れ込んで固化し、仕切板２３が冷蔵庫本体１に一体形成される。 As a result, the urethane foam 4 flows from the urethane discharge port (not shown) between the inner and outer boxes of the refrigerator body 1 into the hollow portion of the partition plate 23 via the urethane filling port 35 and is solidified. It is integrally formed.
このようにして構成したこの冷蔵庫の仕切板２３は、その表面板内面に橋形状のリブ３４があって、この橋形状のリブ３４が仕切板２３の発泡ウレタン４中に埋没していることにより、当該リブ３４が発泡ウレタン４と機械的に結合する形となる。 The partition plate 23 of the refrigerator configured as described above has a bridge-shaped rib 34 on the inner surface of the surface plate, and the bridge-shaped rib 34 is embedded in the urethane foam 4 of the partition plate 23. The rib 34 is mechanically coupled to the urethane foam 4.
すなわち、リブ３４の橋形状部分と上表面板２３ａとの間に発泡ウレタン４が流れ込んで固化し、発泡ウレタン４とリブ３４の橋形状両端鉤状部分とが機械的に結合する形となる。 That is, the foamed urethane 4 flows between the bridge-shaped portion of the rib 34 and the upper surface plate 23a and is solidified, and the foamed urethane 4 and the bridge-shaped both ends of the rib 34 are mechanically coupled.
したがって、仕切板２３の上表面板２３ａが発泡ウレタン４から剥離するのを抑制することができる。 Therefore, the upper surface plate 23a of the partition plate 23 can be prevented from peeling from the urethane foam 4.
特に、この実施の形態ではリブ３４を橋形状としているから、橋形状両端の二箇所でリ
ブ３４が仕切板２３の上表面板２３ａと連結した形となる。したがって、発泡ウレタン４とリブ３４との機械的結合がより強力なものとなって、剥離防止効果が高いものとなる。すなわち、発泡ウレタン４と機械的結合が可能な鉤状部分Ｘを有する形状としては略Ｌ字状のものが考えられるが、この場合は発泡ウレタン４と機械的に結合する鉤状部分が一箇所で片持ち梁形状となって強度的に若干劣るが、橋形状とすれば発泡ウレタン４と機械的に結合する鉤状部分は橋形状両端の二箇所となって両持ち梁形状となるので機械的結合力が強力なものとなるのである。
In particular, in this embodiment, the ribs 34 have a bridge shape, so that the ribs 34 are connected to the upper surface plate 23a of the partition plate 23 at two locations on both ends of the bridge shape. Therefore, the mechanical bond between the urethane foam 4 and the rib 34 becomes stronger, and the peeling prevention effect is high. That is, as the shape having the hook-shaped portion X that can be mechanically coupled to the urethane foam 4, a substantially L-shaped shape is conceivable. In this case, there is one hook-shaped portion mechanically bonded to the urethane foam 4. However, the strength of the cantilever is slightly inferior in the shape of a cantilever. The bond strength is strong.
また、この実施の形態では、上記橋形状のリブ３４は仕切板２３の前方左右に設けたウレタン充填口３５の開口面と交差するように設けてあるから、ウレタン充填口３５から仕切板２３の中空部分に流れ込む発泡ウレタン４は、仕切板２３の上表面板２３ａ内面とリブ３４の橋形状部分との間に確実に流れ込んで充填固化することになる。したがって、発泡ウレタン４と橋形状のリブ３４との機械的結合は確実なものとなり、より確実に仕切板２３の上表面板２３ａと発泡ウレタン４との剥離を抑制することができる。 Further, in this embodiment, the bridge-shaped ribs 34 are provided so as to intersect the opening surfaces of the urethane filling ports 35 provided on the front left and right sides of the partition plate 23. The foamed urethane 4 flowing into the hollow portion surely flows between the inner surface of the upper surface plate 23a of the partition plate 23 and the bridge-shaped portion of the rib 34 and is solidified. Therefore, the mechanical coupling between the foamed urethane 4 and the bridge-shaped rib 34 is reliable, and the separation between the upper surface plate 23a of the partition plate 23 and the foamed urethane 4 can be more reliably suppressed.
更に、上記仕切板２３は冷蔵庫本体１への発泡ウレタン充填によって同時に発泡ウレタンを充填することができるから、生産性を高めつつ仕切板２３の上表面板２３ａと発泡ウレタン４との剥離防止を行うことができる。 Furthermore, since the partition plate 23 can be filled with foamed urethane by filling the refrigerator body 1 with foamed urethane, the partition plate 23 is prevented from peeling off the upper surface plate 23a and the foamed urethane 4 while improving productivity. be able to.
また、前記橋形状のリブ３４は仕切板２３の前部と後部にそれぞれ左右複数列設するとともに、前部に設けたリブ３４ａの前後長Ｌは後部に設けたリブ３４ｂの前後長ｌよりも長くしてあるから、仕切板前部における上表面板２３ａと橋形状のリブ３４との機械的結合を仕切板全部全域にわたってより強力に行うことができる。 The bridge-shaped ribs 34 are provided in a plurality of rows on the left and right sides of the front and rear portions of the partition plate 23, and the longitudinal length L of the ribs 34a provided on the front portion is longer than the longitudinal length l of the ribs 34b provided on the rear portion. Since the length is increased, the mechanical connection between the upper surface plate 23a and the bridge-shaped rib 34 in the front portion of the partition plate can be more strongly performed over the entire partition plate.
したがって、扉１０を開けたときに目につきやすい仕切板２３前部における剥離を効果的に防止することができる。特にこの実施の形態では、仕切板２３の後部はパーシャル室５ａで覆われていて前部のみが扉開成時に目につくので効果的である。 Therefore, it is possible to effectively prevent peeling at the front portion of the partition plate 23 that is easily noticeable when the door 10 is opened. In particular, this embodiment is effective because the rear portion of the partition plate 23 is covered with the partial chamber 5a and only the front portion is noticeable when the door is opened.
更に、前記仕切板２３の扉軸支部近傍に位置するリブ３４ａａは他の中心部寄り部分のリブ３４ａｂよりも仕切板２３の前端面寄り部分に設けてあるから、扉１０を軸支した仕切板２３左右部分の上表面板２３ａとリブ３４との機械的結合が前端面側で行われるようになる。 Further, the rib 34aa located in the vicinity of the door shaft support portion of the partition plate 23 is provided closer to the front end surface of the partition plate 23 than the rib 34ab close to the other center portion. 23 The mechanical connection between the upper surface plate 23a and the rib 34 on the left and right portions is performed on the front end face side.
したがって、扉荷重が加わって前下がり状態に変形しやすい仕切板２３両端の軸支持部近傍の上表面板２３ａと発泡ウレタン４との剥離を効果的に抑制することができる。 Therefore, it is possible to effectively suppress peeling between the upper surface plate 23a and the urethane foam 4 in the vicinity of the shaft support portions at both ends of the partition plate 23, which is easily deformed to the front-down state due to the door load.
加えて、仕切板２３の扉軸支部近傍に位置するリブ３４ａａ以外の他の中心部寄り部分のリブ３４ａｂは仕切板２３の前後方向略中央部分に位置することになって仕切板２３略中央部分の上表面板２３ａと発泡ウレタン４との機械的結合を確保するので、仕切板２３全面に亘って良好な機械的結合を確保することができる。 In addition, the rib 34ab near the central portion other than the rib 34aa located in the vicinity of the door shaft support portion of the partition plate 23 is positioned at the substantially central portion in the front-rear direction of the partition plate 23, and thus the substantially central portion of the partition plate 23. Since the mechanical coupling between the upper surface plate 23a and the urethane foam 4 is ensured, good mechanical coupling can be secured over the entire surface of the partition plate 23.
更にこの実施の形態では、図１０に示すように、前記仕切板２３の左右の軸支持部分となる前端面には補強金具３３を設け、この補強金具３３の端部３３ｂを冷蔵庫本体１の側板部前端面１ａａまで伸ばしてこの側板部前端面１ａａにビス止め固定してあるから、仕切板２３の軸支持部分の前下がり変形をこの補強金具３３によっても確実に防止でき、仕切板２３の軸支持部分近傍の上表面板２３ａと発泡ウレタン４との剥離をより効果的に抑制することができる。 Further, in this embodiment, as shown in FIG. 10, a reinforcing metal fitting 33 is provided on the front end surface which becomes the left and right shaft support portions of the partition plate 23, and the end 33 b of the reinforcing metal fitting 33 is connected to the side plate of the refrigerator main body 1. Since this is extended to the front end face 1aa of the part and fixed to the front end face 1aa of the side plate by screws, the lowering deformation of the shaft support portion of the partition plate 23 can be reliably prevented by the reinforcing bracket 33, and the shaft of the partition plate 23 can be prevented. Separation of the upper surface plate 23a and the urethane foam 4 in the vicinity of the support portion can be more effectively suppressed.
すなわち、補強金具３３の端部３３ｂを冷蔵庫本体１の側板部前端面１ａａまで伸ばして固定したことにより、仕切板２３の扉軸支部にかかる扉１０の荷重は補強金具３３を固
定した冷蔵庫本体１の側板部前端面１ａａによっても支持されるようになり、仕切板２３前端面の前下がり変形を強力に防止できるようになるのである。
That is, the end 33b of the reinforcing bracket 33 is extended and fixed to the front end face 1aa of the side plate portion of the refrigerator main body 1 so that the load of the door 10 applied to the door shaft support portion of the partition plate 23 is the refrigerator main body 1 to which the reinforcing bracket 33 is fixed. The side plate portion front end surface 1aa is also supported, and the front lower end deformation of the partition plate 23 front end surface can be strongly prevented.
これにより、前記扉軸支部近傍に位置するリブ３４ａａを他の中心部寄り部分のリブ３４ａｂよりも仕切板２３の前端面寄り部分に設けたことによる効果と相まってより効果的に仕切板２３の軸支部近傍の上表面板２３ａと発泡ウレタン４との剥離を防止できるのである。 Thereby, the shaft of the partition plate 23 is more effectively coupled with the effect of providing the rib 34aa located in the vicinity of the door shaft support portion closer to the front end surface of the partition plate 23 than the rib 34ab near the other central portion. It is possible to prevent the upper surface plate 23a and the urethane foam 4 from peeling off in the vicinity of the support portion.
以上、本発明に係る冷蔵庫について、上記実施の形態を用いて説明したが、本発明は、これに限定されるものではない。すなわち、今回開示された実施の形態はすべての点で例示であって制限的なものではないと考えられるべきである。つまり、本発明の範囲は上記した説明ではなくて特許請求の範囲によって示され、特許請求の範囲と均等の意味及び範囲内でのすべての変更が含まれることが意図される。 As mentioned above, although the refrigerator concerning this invention was demonstrated using the said embodiment, this invention is not limited to this.

That is, the scope of the present invention is shown not by the above description but by the scope of claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.
例えば、この実施の形態では、仕切板２３の表面板内面に設けたリブ３４は橋形状の形態としたが、これは発泡ウレタン４中に埋没してこれと機械的に結合可能な鉤状部分Ｘを有する形状、例えば既述した略Ｌ字状の形態であってもよいものである。 For example, in this embodiment, the rib 34 provided on the inner surface of the surface plate of the partition plate 23 has a bridge shape, but this is a hook-shaped portion that can be buried in the urethane foam 4 and mechanically coupled thereto. A shape having X, for example, the substantially L-shaped form described above may be used.
また、リブ３４は仕切板２３の冷蔵室底面となる上表面板２３ａに設けたものを例示したが、これは切替室６及び製氷室７の天井面となる下表面板２３ｂ側にも設けてもよいものである。そして、リブ３４を設ける仕切板としては仕切板２３に限られず他の仕切板２４、２５、すなわち貯蔵室の間を仕切る仕切板のいずれであってもよいものである。 In addition, the ribs 34 are provided on the upper surface plate 23a which is the bottom surface of the refrigerator compartment of the partition plate 23, but this is also provided on the lower surface plate 23b side which is the ceiling surface of the switching chamber 6 and the ice making chamber 7. Is also good. And as a partition plate which provides the rib 34, it is not restricted to the partition plate 23, It may be any of the other partition plates 24 and 25, ie, the partition plate which partitions between storage chambers.
更に、仕切板２３には前後に分けてリブ３４を設けたが、剥離防止を必要とする部分のみに設けてもよいものである。 Further, the partition plate 23 is provided with the ribs 34 in the front and rear directions, but may be provided only in a portion that requires prevention of peeling.
また、仕切板２３の前後に分けてリブ３４を設ける場合、後部に設けたリブ３４は前部に設けたリブ３４よりも短くしたが、これは同じ長さにしてもよいし、前部に設けたリブ３４のうち、軸支部近傍のリブ３４は仕切板前端面寄り部分に設けたが、他のリブ３４も仕切板前端部分に設けてその前後長を後方へ長く延ばすことにより仕切板略中央部分での剥離防止も確保可能としてもよいものである。 Further, when the ribs 34 are provided separately on the front and rear sides of the partition plate 23, the ribs 34 provided at the rear part are shorter than the ribs 34 provided at the front part, but this may be the same length, Of the provided ribs 34, the ribs 34 in the vicinity of the shaft support portion are provided near the front end face of the partition plate, but the other ribs 34 are also provided at the front end portion of the partition plate, and the length of the front and rear thereof is extended to the rear to shorten the partition plate. It is also possible to ensure separation prevention at the central portion.
