將構成外箱的外側側板1與構成内箱的内側側板3空開間 隔重疊而構成。於外侧侧板1與内側侧板3之間設發二 201115089 隔熱材5及真空隔熱材7 ^於真空隔熱材7的一面、即， 接近與鄰接發泡隔熱材5的面為相反側的外侧側板1的一 側的面上，上下方向地形成有凹槽9。凹槽9内設有散熱 管η。 用以設置散熱管11的凹槽9的上端是在夾持著真空 隔熱材7的外側側板1與内側側板3之間的上部空間處形 成開口 ’發泡胺基甲酸酯自該上部的開口進入，在凹槽9 内發泡並固化。 於第一實施形態的冰箱10中，在外側侧板1與真空 隔熱材7之間設有薄片21，藉此使外側側板1不會因伴隨 滲入凹槽9的液體狀態的發泡胺基曱酸酯的固化產生的收 縮而凹下變形。 如下述般、薄片21是遍及外側側板1的大致整個表 面而鄰接，且設於外側側板1與真空隔熱材7之間。藉此， 第一實施形態的冰箱10的壁部是由外側側板1、薄片21、

PET)組成的群組中的材料構成，平滑且具 有熱反射性便可。 圖4及圖5是整體表示圖3所示的第一實施形態的應 用了薄片21的冰箱1〇的某一面的壁部上將内側側板3與 發泡隔熱材5除去後的剩餘部分的壁部的僅一面的立體圖 及其分解立體圖。即、圖4及圖5中，如圖3所示，對於 由外侧側板1、薄片21、於凹槽9内設有散熱管11的真空 隔熱材7、發泡隔熱材5、内側側板3構成的壁部中，僅圖 示除内側側板3及發泡隔熱材5以外的外側側板1、薄片 21、於凹槽9内設有散熱管11的真空隔熱材7。於圖4及 圖5中，外侧侧板1的對向侧、即，偏右後方，為冰箱 的外側，真空隔熱材7的近前側、即，偏左前方，為冰箱 1〇的内側。 如圖4及圖5所示，於外側侧板1與凹槽9内設有散 熱管11的真空隔熱材7之間，薄片21遍及外側側板1的 大致整個表面而鄰接設置。為使發泡隔熱材5不滲入薄片

薄片21拉伸，而不會影響到外侧側板丨，從而可防止外側 侧板1的變形。 如圖4及圖5所示，散熱管11是以在垂直方向、即， 水相10的上下方向延伸的方式没置著，故此種用以設置散 熱管11的凹槽9亦為於真空隔熱材7的一面上形成為在垂 直方向、即，冰箱10的上下方向延伸。凹槽9的上下端是 於夾持著真空隔熱材7的外侧側板丨與圖4、5中省略的内 側側板3之間的上下部的空間處形成開口。 於夾持著真空隔熱材7的外侧侧板丨與内側側板3之 間j間隙處，自外側侧板丨的適當部位打開的小孔以液體 狀恕注入發泡胺基甲酸酯，使其遍及整個間隙並發泡。藉 此，發泡胺基甲酸酯以如圖2或圖3所示的方式填充於夾 持著真空隔熱材7的外側側板丨與内側側板3之間的整個 工間，且發泡並固化，藉此，如圖2或圖3所示構成發泡 隔熱材5。 山該發泡時，由於真空隔熱材7上形成的凹槽9的上下 端為開口狀態’故液體狀態的發泡胺基甲酸酯如上述般注 入夹持著真空隔熱材7的外側側板1與内側側板3之間的 同時’亦自凹槽9的上下端進入凹槽9内少許，並於凹槽 9内發泡。如此一來進入凹槽9内的液體狀態的發泡胺基 201115089 曱酸酯附著於將面向外侧侧板1的内側的凹槽9的開放部 予以堵塞的薄片21的内側。 ° 如此’進入凹槽9内且附著於薄片21内側的液體狀

會有損散熱管11的散熱效果。此外，上述說明是對左右任 一單側的結構進行描述，但左右兩側的側板亦可為相同結 構。而且，冰箱10的背面亦可設為相同結構。 [第2實施形態] 圖6表示第2實施形態的冰箱10A的一面的壁部上將 内侧側板3與發泡隔熱材5除去後的剩餘部分的壁部的結 構。 、。 圖3〜圖5所示的第一實施形態的冰箱的壁部上， 薄片21是遍及外側侧板1的大致整個表面而設置，相對於 此第2實施形態的冰箱10A的壁部而存在如下不同點：於 凹槽9的上下端露出的外側側板1的上部，以覆蓋包含凹 槽9上端的凹槽9的上部的方式而設有小薄片23。該配置 位置與圖3〜圖5所示的第一實施形態同樣地處於外側侧 板1與真空隔熱材7之間。 11 201115089r 該小薄片23與圖3〜圖5所示的第一實施形態同樣 地，為使發泡隔熱材5不滲入薄片23與外側側板1之間， 至少周邊部黏接或貼附於外側側板1 ^除該周邊部以外的 内側部分處於不黏接或不貼附於外侧側板1、而是處於自 外側側板1漂浮且可分離的狀態。當發泡隔熱材5滲入凹 槽9内時’外側側板1有可能會因所滲入的發泡隔熱材5 的收縮而向内側拉伸，使得外側側板1產生凹下，但由於 薄片21處於與外側側板1可分離的狀態’故即便發泡隔熱 材5產生收縮，亦僅薄片21拉伸，而不會影響到外侧側板 1 ’從而可防止外側側板1的變形。 如此，於外側侧板1的上部，以堵塞配設有散熱管U 的凹槽9上部的開放部的方式而在外侧侧板1與真空隔熱 材7之間設置小薄片23，藉此可防止特別容易引人注目的 外側側板1的上部的變形，且與圖3〜圖5所示的第一實 施形態相比，可低成本地製造。 於第2貝施形態中’是將小薄片23以覆蓋包含凹槽9 上端的凹槽9的上部的方式而設置在外側側板1的上部， 但實際上由於凹槽9的下端也開口，故亦可於該下端上黏 接或貼附小薄片23。其中，自該下端滲入的液體狀態的發 泡胺基甲酸醋極其少董’對冰箱10 A的壁部變形的景;；塑 小，假設即便發生滲入並因此導致冰箱10A下部的側壁變 形，與冰箱10A上部的壁部相比亦不容易引人注目。雖說 如此’但除了可將小薄片23以覆蓋包含凹槽9上端的凹槽 9的上部的方式而設置於外侧侧板1的上部以外，亦可二 12 201115089 覆蓋包含凹槽9下端的凹槽9的下部的方式而設置於外側 側板1的下部，還可以此方式於上下兩方黏接或貼附小薄 片23，即便如此在與圖3所說明的第一實施形態相比之 下，亦可實現經濟化。 [第三實施形態] 圖7是表示第三實施形態的冰箱10B的一面的壁部上 將内侧側板3與發泡隔熱材5除去後的剩餘部分的壁部的 結構。 圖7所示的第三實施形態的冰箱10B的壁部，是如圖 6所示的第2實施形態的冰箱i〇A的壁部僅覆蓋凹槽9的 上端部般、自真空隔熱材7的上部遍及薄片23而貼附膠帶 25，藉此而堵塞凹槽9的上端開口。藉此，可防止發泡胺 基曱酸酯自凹槽9的上端進入凹槽9内的情況。 根據第三實施形態，由於發泡胺基甲酸酯不會進入凹 槽9内，故只要未附著於外侧側板1的内側，便不會因發 泡胺基曱酸酯的固化、收縮而發生外側側板1的凹下或變 形。假設即便因貼附於凹槽9上端的膠帶25的一部分剝離 等，使得液體狀態的發泡胺基甲酸酯自該一部分進入凹槽 9内，或者自小間隙進入，由於外側侧板1的上部存在設 置於外側侧板1與真空隔熱材7之間的小薄片23，與上述 圖6的第2實施形態同樣地外側側板1亦不會凹下變形。 圖7的第三實施形態―的膠帶25的貼附不僅可適用於 如圖6所示的第2實施形態般將小薄片23僅設於外側侧板 1上部的情況，且亦可適用於如圖3〜圖5的第一實施形態 13 201115089 般遍及外側側板1的大致整個表面而貼附薄片21的情況。 可由利用柔軟材料形成的例如丁基膠帶、丁基橡膠 帶、聚胺基曱酸酯膠帶、紙膠帶及膠帶組成的群組中選擇 膠帶25。 於上述各實施形態中，是以本發明應用於冰箱1〇、 10A、10B側面的壁部為例進行說明，但本發明並不限定 於此，亦可應用於冰箱1 〇 ' 1 〇 A、10B頂側的壁部或背面 側的壁部專所需部位，此種天井側的壁部或背面側的壁部 等亦如上述般、由外侧側板與内側侧板夾持真空隔熱材、 發泡隔熱材而構成。 根據以上所說明的實施形態，於形成有用以配設散熱 管11的凹槽/的真空隔熱材7的面與鄰接該面的外側侧板 1之間设有薄片21、23，故進入凹槽9内的液體狀態的發 泡胺基曱酸酯不會附著於外側侧板i而是附著於薄片21、 23上。而且，薄片21、23是以相對於外側側板丨漂浮且 可分離的狀態而設置。因此，即便附著於該薄片21、 上的發泡胺基甲酸酯於凹槽9内發泡並固化冷卻後收縮， 亦僅薄片21、23向凹槽9内拉伸而凹下變形，外側侧板i 不會受到薄片21、23的變形的影響，故不會凹下或變形。 由此，冰箱10、l〇A、10B的外觀不會變差。 雖然本發明已以實施例揭露如上，然其並非用以限定

That is, in FIGS. 4 and 5, as shown in FIG. 3, the outer side panel 1, the sheet 21, the vacuum heat insulating material 7 in which the heat radiation pipe 11 is provided in the recess 9, the foam heat insulating material 5, and the inner side panel are shown. Among the wall portions of the three components, only the outer side plate 1 except the inner side plate 3 and the foam heat insulating material 5, the sheet 21, and the vacuum heat insulating material 7 in which the heat radiation pipe 11 is provided in the groove 9 are illustrated. In Figs. 4 and 5, the opposite side of the outer side panel 1, i.e., the right rear side, is the outer side of the refrigerator, and the front side of the vacuum heat insulating material 7, i.e., the front left side, is the inner side of the refrigerator. As shown in Figs. 4 and 5, between the outer side panel 1 and the recess 9 is provided with a heat insulating material 7 for the heat radiating tube 11, and the sheet 21 is provided adjacent to the substantially entire surface of the outer side panel 1. In order to prevent the foamed heat insulating material 5 from penetrating between the sheet 21 and the outer side panel 1, the sheet 21 is adhered or attached to the outer side panel 1 at least in the peripheral portion as described above. The inner portion other than the peripheral portion is in a state in which it is not adhered or attached to the outer side panel 1 but floats from the outer side panel 1 and can be separated from 201115089. When the foamed heat insulating material 5 penetrates into the recess 9, the outer side panel i may be stretched inward due to the contraction of the foamed heat insulating material 5 which is infiltrated, so that the outer side panel 1 is recessed 'but due to the sheet 21 Since it can be separated from the outer side panel 1, even if the foamed heat insulating material 5 shrinks, only the sheet 21 is stretched, and the outer side panel is not affected, and deformation of the outer side panel 1 can be prevented. As shown in FIGS. 4 and 5, the heat dissipating tube 11 is not disposed in the vertical direction, that is, in the vertical direction of the water phase 10. Therefore, the recess 9 for arranging the heat dissipating tube 11 is also in the vacuum compartment. One surface of the hot material 7 is formed to extend in the vertical direction, that is, in the vertical direction of the refrigerator 10. The upper and lower ends of the recess 9 are formed with openings at the upper and lower spaces between the outer side panel 夹持 sandwiching the vacuum heat insulating material 7 and the inner side panel 3 omitted in Figs. 4 and 5. At a j-gap between the outer side plate 夹持 and the inner side plate 3 sandwiching the vacuum heat insulating material 7, a small hole opened from an appropriate portion of the outer side plate 以 is injected with a foaming urethane in a liquid state, so that It spreads throughout the gap and foams. Thereby, the foamed urethane is filled in the entire space between the outer side panel 夹持 and the inner side panel 3 sandwiching the vacuum heat insulating material 7 as shown in FIG. 2 or FIG. 3, and is foamed and The foamed heat insulating material 5 is formed as shown in Fig. 2 or Fig. 3 by curing. When the foam is foamed, the upper and lower ends of the groove 9 formed in the vacuum heat insulating material 7 are in an open state. Therefore, the foamed urethane in a liquid state is injected into the outer side of the vacuum heat insulating material 7 as described above. The simultaneous 'between the side panel 1 and the inner side panel 3 also enters the recess 9 from the upper and lower ends of the recess 9 and is foamed in the recess 9. The foamed amine group 201115089 phthalate which enters the liquid state in the groove 9 adheres to the inner side of the sheet 21 which blocks the open portion of the groove 9 facing the inner side of the outer side panel 1. ° The foamed urethane in the liquid state which enters the inside of the groove 9 and adheres to the inside of the sheet 21 is foamed in the groove 9 and solidified and cooled, and its volume shrinks, but only the sheet 21 is pulled inward during the shrinkage. The outer side panel 1 in a state in which the sheet 21 is floating and separable, that is, in a state of not adhering or not attached to the sheet 21, does not stretch inward and does not deform. Therefore, in the refrigerator 1 which is first opened, there is no case where the outer side panel 1 is concavely deformed toward the inner side to deteriorate the appearance, and even if it is as described above, the outer side panel 1 and the vacuum heat insulating material 7 are The provision of the sheet 21 between them does not impair the heat dissipation effect of the heat pipe 11. Further, the above description is for describing the structure of any one of the left and right sides, but the side plates of the left and right sides may have the same structure. Further, the back surface of the refrigerator 10 may have the same structure. [Second Embodiment] Fig. 6 shows a structure of a wall portion of the remaining portion of the wall portion of one side of the refrigerator 10A according to the second embodiment, in which the inner side panel 3 and the foamed heat insulating material 5 are removed. ,. In the wall portion of the refrigerator according to the first embodiment shown in FIG. 3 to FIG. 5, the sheet 21 is provided over substantially the entire surface of the outer side panel 1, and the wall portion of the refrigerator 10A of the second embodiment has the following The difference is that the upper portion of the outer side panel 1 exposed at the upper and lower ends of the recess 9 is provided with the small sheet 23 so as to cover the upper portion of the recess 9 including the upper end of the recess 9. This arrangement position is between the outer side panel 1 and the vacuum heat insulating material 7 in the same manner as the first embodiment shown in Figs. 3 to 5 . 11 201115089r In the same manner as the first embodiment shown in FIGS. 3 to 5, the small sheet 23 is such that the foamed heat insulating material 5 does not penetrate between the sheet 23 and the outer side panel 1, and at least the peripheral portion is adhered or attached. The inner side portion of the outer side panel 1 ^ except the peripheral portion is in a state of being non-adhered or not attached to the outer side panel 1 but floating and detachable from the outer side panel 1. When the foamed heat insulating material 5 penetrates into the groove 9, the outer side panel 1 may be stretched inward due to the shrinkage of the foamed heat insulating material 5 which is infiltrated, so that the outer side panel 1 is concave, but due to the sheet 21 In a state in which it is separable from the outer side panel 1, even if the foamed heat insulating material 5 contracts, only the sheet 21 is stretched, and the outer side panel 1' is not affected, so that deformation of the outer side panel 1 can be prevented. In this way, the small portion 23 is provided between the outer side plate 1 and the vacuum heat insulating material 7 so as to block the open portion of the upper portion of the groove 9 in which the heat pipe U is disposed on the upper portion of the outer side plate 1. The deformation of the upper portion of the outer side panel 1 which is particularly noticeable is prevented, and it can be manufactured at a lower cost than the first embodiment shown in Figs. 3 to 5 . In the second Besch embodiment, the small sheet 23 is provided on the upper portion of the outer side panel 1 so as to cover the upper portion of the recess 9 including the upper end of the recess 9, but actually, since the lower end of the recess 9 is also opened, The small sheet 23 may also be adhered or attached to the lower end. Wherein, the foamed amino carboxylic acid vinegar in the liquid state infiltrated from the lower end is extremely less deformed by the wall portion of the refrigerator 10 A; the plastic is small, and it is assumed that even if the infiltration occurs, the side wall of the lower portion of the refrigerator 10A is deformed, and The wall portion of the upper portion of the refrigerator 10A is also less noticeable than the wall portion. Although this is the case, except that the small sheet 23 can be disposed on the upper portion of the outer side panel 1 so as to cover the upper portion of the recess 9 including the upper end of the recess 9, the recess 12 including the lower end of the recess 9 can be covered by 12 201115089. The lower portion of the 9 is disposed on the lower portion of the outer side panel 1, and the small sheet 23 can be adhered or attached to the upper and lower sides in this manner, even in comparison with the first embodiment illustrated in FIG. Achieve economics. [Third Embodiment] Fig. 7 is a view showing a configuration of a wall portion of a remaining portion of the wall portion of one surface of the refrigerator 10B according to the third embodiment in which the inner side plate 3 and the foam heat insulating material 5 are removed. The wall portion of the refrigerator 10B according to the third embodiment shown in Fig. 7 is a vacuum heat insulating material in which the wall portion of the refrigerator i〇A of the second embodiment shown in Fig. 6 covers only the upper end portion of the recess 9. The upper portion of the sheet 7 is attached to the sheet 23 to attach the tape 25, thereby blocking the upper end opening of the recess 9. Thereby, the foaming amine phthalate can be prevented from entering the inside of the groove 9 from the upper end of the groove 9. According to the third embodiment, since the foaming urethane does not enter the inside of the recess 9, it does not adhere to the inner side of the outer side panel 1 and does not occur due to curing or shrinkage of the foaming amine phthalate. The outer side panel 1 is recessed or deformed. It is assumed that even if a part of the tape 25 attached to the upper end of the groove 9 is peeled off or the like, the foamed urethane in a liquid state enters the groove 9 from the portion or enters from a small gap due to the outer side plate 1 The small sheet 23 provided between the outer side panel 1 and the vacuum heat insulating material 7 is present in the upper portion, and the outer side panel 1 is not concavely deformed as in the second embodiment of Fig. 6 described above. The attachment of the tape 25 of the third embodiment of FIG. 7 can be applied not only to the case where the small sheet 23 is provided only on the upper portion of the outer side panel 1 as in the second embodiment shown in FIG. 6, but also applicable to, for example, In the first embodiment 13 of FIG. 3 to FIG. 5, the sheet 21 is attached to the substantially entire surface of the outer side panel 1 as in the case of 201115089. The tape 25 may be selected from the group consisting of a butyl tape, a butyl rubber tape, a polyamino phthalate tape, a paper tape, and a tape formed of a soft material. In each of the above embodiments, the wall portion of the side faces of the refrigerators 1A, 10A, and 10B of the present invention is described as an example. However, the present invention is not limited thereto, and may be applied to the refrigerator 1 〇' 1 〇A, 10B is a wall portion on the top side or a wall portion on the back side, and the wall portion on the side of the patio or the wall on the back side is also sandwiched between the outer side panel and the inner side panel as described above. It is composed of a foamed heat insulating material. According to the embodiment described above, the sheets 21 and 23 are provided between the surface of the vacuum heat insulating material 7 for forming the groove/heating pipe 11 and the outer side plate 1 adjacent to the surface, so that the concave portion is formed. The foamed amino phthalic acid ester in a liquid state in the groove 9 does not adhere to the outer side plate i but adheres to the sheets 21 and 23. Further, the sheets 21, 23 are provided in a state of being floated and detachable with respect to the outer side panel. Therefore, even if the foamed urethane adhered to the sheet 21 is foamed in the groove 9 and solidified and cooled to shrink, only the sheets 21 and 23 are stretched into the groove 9 to be concavely deformed, and the outer side is deformed. The side panel i is not affected by the deformation of the sheets 21, 23, so it is not recessed or deformed. Thereby, the appearance of the refrigerators 10, 10A, 10B does not deteriorate. The present invention has been disclosed in the above embodiments, but it is not intended to limit the present invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the present invention. The scope of the warranty is subject to the definition of the scope of the patent application.
