Description
本發明係關於冰箱。尤其是關於真空隔熱材的折角。 The present invention relates to a refrigerator. Especially regarding the folding angle of vacuum insulation.
亟需要有節能的家電製品。例如，在冰箱中，將發泡隔熱材填充到冰箱的外箱和內箱之間的空間，以防止冷氣從冰箱內漏出，或者熱氣從外部侵入。而且，在冰箱中，為了更進一步節省能源，而尋求隔熱性能更佳的隔熱材。 亟 There is a need for energy-efficient home appliances. For example, in a refrigerator, a foamed heat insulating material is filled in a space between an outer box and an inner box of a refrigerator to prevent leakage of cold air from the inside of the refrigerator, or intrusion of hot air from the outside. Moreover, in the refrigerator, in order to further save energy, a heat insulating material having better heat insulation properties is sought.
因此，已有提出如後述的冰箱：例如將發泡隔熱材從冰箱背面側的注入口填充到冰箱的外箱和內箱之間，把空間填上，不只如此，還在裝上真空隔熱材後再填充發泡隔熱材，藉此更進一步達到隔熱的效果。真空隔熱材係將作為墊片(spacer)的芯材***有阻氣(gas barrier)性的外包材中，再以將外包材壓縮等方式，使外包材內部減壓，再密封而形成。 Therefore, there has been proposed a refrigerator which will be described later. For example, the foamed heat insulating material is filled from the injection port on the back side of the refrigerator to the outer box and the inner box of the refrigerator, and the space is filled in, and not only the vacuum partition is installed. After the hot material is filled with the foamed heat insulating material, the heat insulating effect is further achieved. The vacuum heat insulating material is formed by inserting a core material of a spacer into a gas barrier outer covering material, and then decompressing the inside of the outer covering material by compressing the outer covering material or the like.
在此，例如配合空間的形狀形成真空隔熱材的芯材。並且，在外周部分進行熱熔接，以使得空氣等不會在減壓後進入外包材內部。因此，真空隔熱材的外周部分就成了沒有塞入芯材的剩餘部分的邊角(耳部)。 Here, for example, the core material of the vacuum heat insulating material is formed in the shape of the space. Further, heat welding is performed on the outer peripheral portion so that air or the like does not enter the inside of the outer covering material after being decompressed. Therefore, the outer peripheral portion of the vacuum heat insulating material becomes a corner (ear portion) which is not inserted into the remaining portion of the core material.
例如，若就這樣讓安裝在冰箱的外箱和內箱之間的真空隔熱材的邊角放著不去管它，那麼邊角就會阻礙發泡隔 熱材的填充，可能會使發泡隔熱材的材料變多。因此而提出了如後述的真空隔熱材：將真空隔熱材的邊角折起(折角)並固定邊角，再安裝於冰箱(例如參照專利文獻1)。 For example, if the corner of the vacuum insulation material installed between the outer box and the inner box of the refrigerator is left unattended, the corners will hinder the foaming partition. The filling of the hot material may increase the amount of material of the foamed heat insulating material. Therefore, a vacuum heat insulating material as described later is proposed in which the corners of the vacuum heat insulating material are folded (folded) and fixed at the corners, and then attached to the refrigerator (see, for example, Patent Document 1).
專利文獻1：日本特開2013-245909號公報 Patent Document 1: Japanese Laid-Open Patent Publication No. 2013-245909
但是，例如，安裝已折角的真空隔熱材之後，再將發泡隔熱材填充於外箱和內箱之間的空間。此時，存在於空間中的一部分的空氣不能排出而滯留在空間內。例如，滯留的空氣在真空隔熱材的折角部分無處可逃而滯留在那。若在空氣滯留著的狀態下運轉冰箱，則滯留著的空氣會膨脹或收縮等，對內箱和外箱的壁面施力，而可能會造成冰箱內外壁面的變形等。例如，在專利文獻1中，雖然有進行切斷邊角等的加工，但並沒有對於空氣採取對策。 However, for example, after the folded vacuum heat insulating material is attached, the foamed heat insulating material is filled in the space between the outer box and the inner box. At this time, a part of the air existing in the space cannot be discharged and stays in the space. For example, the trapped air has nowhere to escape in the chamfered portion of the vacuum insulation material and stays there. When the refrigerator is operated while the air is stagnation, the stagnant air may expand or contract, and the wall surfaces of the inner box and the outer box may be biased, which may cause deformation of the inner and outer wall surfaces of the refrigerator. For example, in Patent Document 1, although processing for cutting a corner or the like is performed, no countermeasure against air is taken.
本發明係為了解決如上述的課題，其目的在於提供一種冰箱，其能夠降低耗電量，並且避免因為真空隔熱材的折角而造成的變形。 The present invention has been made to solve the above problems, and an object thereof is to provide a refrigerator capable of reducing power consumption and avoiding deformation due to a folding angle of a vacuum heat insulating material.

另外，本實施形態的冰箱100的冰箱箱體1a，在外箱20和內箱30之間具有發泡隔熱材40和真空隔熱材41，以將冰箱100內外隔熱。 Further, in the refrigerator casing 1a of the refrigerator 100 of the present embodiment, the foamed heat insulating material 40 and the vacuum heat insulating material 41 are provided between the outer casing 20 and the inner casing 30 to insulate the inside and outside of the refrigerator 100.
真空隔熱材41固定在側面板21及背面板22的冰箱內面側。另外，發泡隔熱材40填充於外箱20和內箱30之間的空間。將真空隔熱材41固定在側面板21及背面板22，藉此使得發泡隔熱材40不會侵入側面板21及背面板22與真空隔熱材41之間。因此，能夠發揮真空隔熱材41的隔熱效果。關於發泡隔熱材40的填充於下文中敘述。 The vacuum heat insulating material 41 is fixed to the inner surface side of the refrigerator of the side panel 21 and the back panel 22. Further, the foamed heat insulating material 40 is filled in a space between the outer box 20 and the inner box 30. The vacuum heat insulating material 41 is fixed to the side panel 21 and the back surface panel 22, whereby the foam heat insulating material 40 does not intrude between the side panel 21 and the back panel 22 and the vacuum heat insulating material 41. Therefore, the heat insulating effect of the vacuum heat insulating material 41 can be exhibited. The filling of the foamed heat insulating material 40 is described below.
第4圖及第5圖為表示本發明實施形態1的放熱管16和真空隔熱材41之關係的一例之圖。如前所述，本實施形態的真空隔熱材41，至少固定在側面板21及背面板22的內面側。此時，固定在側面板21的真空隔熱材41覆蓋住作為凝縮器的放熱管16，將放熱管16一起固定住。 4 and 5 are views showing an example of the relationship between the heat radiation pipe 16 and the vacuum heat insulating material 41 according to the first embodiment of the present invention. As described above, the vacuum heat insulating material 41 of the present embodiment is fixed to at least the inner surface side of the side panel 21 and the back panel 22. At this time, the vacuum heat insulating material 41 fixed to the side panel 21 covers the heat radiation pipe 16 as a condenser, and the heat radiation pipe 16 is fixed together.
放熱管16，係如前述具有凝縮器的功能，並透過側面板21將冷媒的熱放熱到冰箱100的外部。在本實施形態中，放熱管16為直徑約4.0~5.0mm的銅管。另外，固定在各側面板21的放熱管16，係分別由1支銅管在上下方向反覆折彎而成。因此，能夠在有限的範圍內拉長冷媒的流路。此時，反覆折彎所形成的相鄰銅管的間隔為尺寸W1。在此，放熱管16的形狀、材料、尺寸等不限定於第4圖及第5圖的例子。 The heat release pipe 16 has a function of a condenser as described above, and heats the heat of the refrigerant to the outside of the refrigerator 100 through the side panel 21. In the present embodiment, the heat release tube 16 is a copper tube having a diameter of about 4.0 to 5.0 mm. Further, the heat release tubes 16 fixed to the side panels 21 are each formed by repeatedly bending one copper tube in the vertical direction. Therefore, the flow path of the refrigerant can be elongated within a limited range. At this time, the interval between the adjacent copper tubes formed by the reverse bending is the dimension W1. Here, the shape, material, size, and the like of the heat release tube 16 are not limited to the examples of FIGS. 4 and 5.
真空隔熱材41隔熱以使得熱不會從外部侵入冰箱100內。另外，用真空隔熱材41覆蓋住放熱管16，藉此也隔絕 了從冷媒而來的放熱。真空隔熱材41具有覆蓋放熱管16的凹部42。如前述，因為銅管的反覆折彎而形成的彼此相鄰銅管之間隔為尺寸W1。因此，凹部42間的間隔也是尺寸W1。另外，凹部42的深度(高度)的尺寸D1為放熱管16的直徑以上。此係為了在填充發泡隔熱材40時，不會因為真空隔熱材41和放熱管16接觸，並對放熱管16加壓，而壓到側面板21等造成其外觀不良。而且，在本實施形態中的凹部42的寬幅之尺寸L1為40~70mm。凹部42的寬幅的尺寸L1，要考慮到冰箱製造程序中所發生的組裝公差。組裝公差係為例如：形成凹部42時的製造誤差、將真空隔熱材41安裝在側面板21時的安裝誤差、側面板21之放熱管16的彎曲、放熱管16對側面板21的安裝誤差等。凹部42的寬幅之尺寸L1設定為，即使發生了上述誤差，凹部42也能收納放熱管16。 The vacuum heat insulating material 41 is insulated so that heat does not intrude into the refrigerator 100 from the outside. In addition, the heat-dissipating tube 16 is covered with the vacuum heat insulating material 41, thereby also isolating The heat from the refrigerant. The vacuum heat insulating material 41 has a recess 42 that covers the heat release tube 16. As described above, the interval between the adjacent copper tubes formed by the reverse bending of the copper tubes is the size W1. Therefore, the interval between the recesses 42 is also the dimension W1. Further, the dimension D1 of the depth (height) of the recess 42 is equal to or larger than the diameter of the heat radiation pipe 16. In order to fill the foamed heat insulating material 40, the vacuum heat insulating material 41 and the heat radiating pipe 16 are not brought into contact with each other, and the heat radiating pipe 16 is pressurized, and pressed to the side panel 21 or the like causes a poor appearance. Further, the width L1 of the recess 42 in the present embodiment is 40 to 70 mm. The wide dimension L1 of the recess 42 takes into account the assembly tolerances that occur in the refrigerator manufacturing process. The assembly tolerance is, for example, a manufacturing error when the concave portion 42 is formed, an installation error when the vacuum heat insulating material 41 is mounted on the side panel 21, a bending of the heat radiation pipe 16 of the side panel 21, and a mounting error of the heat radiation pipe 16 to the side panel 21. Wait. The dimension L1 of the width of the recess 42 is set such that the recess 42 can accommodate the heat radiation tube 16 even if the above error occurs.
<真空隔熱材41的構成> <Configuration of Vacuum Heat Insulation Material 41>
真空隔熱材41具有外包材43及芯材44。外包材43包住芯材44以保護之。另外，還保持內部的真空狀態。外包材43的材料為，例如具有熱熔接用的塑膠層的金屬蒸鍍層合膜(laminated film)等。另一方面，芯材44係為複數層的積層體45重疊而成。在本實施形態中，如後述，係將三層的積層體45重疊，以製作芯材44。一般而言，積層體45之材料為，玻璃絨(glass wool)、玻璃纖維、氧化鋁纖維(alumina fiber)、氧化矽氧化鋁纖維(纖維)、木綿等的天然纖維等。 The vacuum heat insulating material 41 has an outer covering 43 and a core 44. The outer covering 43 encases the core 44 to protect it. In addition, the internal vacuum state is maintained. The material of the outer covering material 43 is, for example, a metal vapor deposited laminated film having a plastic layer for heat fusion. On the other hand, the core material 44 is formed by laminating a plurality of laminated bodies 45 of a plurality of layers. In the present embodiment, as will be described later, the three-layered laminated body 45 is stacked to form the core material 44. In general, the material of the laminate 45 is glass wool, glass fiber, alumina fiber, yttria alumina fiber ( Natural fibers such as fibers) and wood wool.
第6圖為依時序說明本發明實施形態1的真空隔熱材41的製造程序的圖。繼之，基於第6圖，說明真空隔熱材41 的製造程序。在此，在製造過程中各積層體45及芯材44的厚度會有變化，但在第6圖中沒有讓它改變。另外，第6圖僅為一例，例如在第二積層體45d上積層的第一積層體45a、45b及45c的積層體45的數目等，並不限於此例。 Fig. 6 is a view showing a procedure for manufacturing the vacuum heat insulating material 41 according to the first embodiment of the present invention in a time series. Next, based on Fig. 6, a vacuum heat insulating material 41 will be described. Manufacturing process. Here, the thickness of each of the laminated body 45 and the core material 44 may vary during the manufacturing process, but it is not changed in Fig. 6. In addition, FIG. 6 is only an example, and the number of the laminated bodies 45 of the first laminated bodies 45a, 45b, and 45c laminated on the second laminated body 45d, for example, is not limited to this example.
首先，將作為芯材44材料的原綿之無機纖維予以乾燥。將乾燥後的無機纖維切成特定的尺寸，形成第一積層體45a、45b及45c、第二積層體45d還有第三積層體45e。然後，如第6圖(a)所示，將第一積層體45a、45b及45c、第二積層體45d還有第三積層體45e積層為3層，形成芯材44。在此，在第三積層體45e的上側配置第二積層體45d。另外，在第二積層體45d的上側配置第一積層體45a、45b及45c。調整第一積層體45a、45b及45c的配置，以調整凹部42的寬幅之尺寸L1。另外，第一積層體45a、45b及45c的厚度為，例如減壓後的厚度為5mm。而且，如第6圖(b)所示，用外包材43包住芯材44。在本例中，外包材43係形成為袋狀，在用於***芯材44而開口的部分以外的外周部，則為由熱熔接所形成之邊角46。例如在真空隔熱材41的外周端部形成20~50mm的寬幅之邊角46。 First, the inorganic fibers of the primary cotton as the material of the core material 44 are dried. The dried inorganic fibers are cut into specific sizes to form first laminates 45a, 45b, and 45c, second laminate 45d, and third laminate 45e. Then, as shown in Fig. 6(a), the first layered bodies 45a, 45b, and 45c, the second layered body 45d, and the third layered body 45e are laminated into three layers to form a core material 44. Here, the second layered body 45d is disposed on the upper side of the third layered body 45e. Further, the first layered bodies 45a, 45b, and 45c are disposed on the upper side of the second layered body 45d. The arrangement of the first laminates 45a, 45b, and 45c is adjusted to adjust the width L1 of the width of the recess 42. Further, the thickness of the first layered bodies 45a, 45b, and 45c is, for example, a thickness of 5 mm after pressure reduction. Further, as shown in Fig. 6(b), the core material 44 is wrapped with the outer covering material 43. In this example, the outer covering material 43 is formed in a bag shape, and the outer peripheral portion other than the portion for opening the core material 44 is a corner 46 formed by heat welding. For example, a wide corner 46 of 20 to 50 mm is formed at the outer peripheral end portion of the vacuum heat insulating material 41.
再者，將由外包材43包住的芯材44載置於真空室(未圖示)內。然後，用沖壓機床50加壓芯材44，同時使外包材43內的空氣從外包材43未熔接的部分排出，並將芯材44壓縮到特定的厚度。例如，當外包材43內變成真空狀態時，如第6圖(c)所示，熔接機60將熱施加於外包材43的開口部分以將其熔接，將開口部分封閉，藉此在真空隔熱材41的整個周圍形成作為外周部的邊角46。 Further, the core material 44 surrounded by the outer covering material 43 is placed in a vacuum chamber (not shown). Then, the core material 44 is pressed by the press machine 50 while the air in the outer covering 43 is discharged from the unfused portion of the outer covering member 43, and the core member 44 is compressed to a specific thickness. For example, when the inside of the outer covering material 43 is in a vacuum state, as shown in Fig. 6(c), the fusion splicer 60 applies heat to the opening portion of the outer covering member 43 to weld it, and closes the opening portion, thereby separating the vacuum portion. The entire circumference of the hot material 41 forms a corner 46 as a peripheral portion.
在此，例如，本實施形態的芯材44具有凹部42，但若在凹部42的部分之空氣未排出的狀態下把外包材43密封的話，則芯材44會在大氣中變形，使得凹部42的高度變矮。另外，在與形成凹部42的面相反的面也形成凹凸。因此，隔熱性能降低。因此，事先在沖壓機床50形成與凹部42的形狀相吻合的凸面，於進行沖壓之後，就能把凹部42的空氣排出。藉由上述方式，如第6圖(d)所示，製造出真空隔熱材41。 Here, for example, the core material 44 of the present embodiment has the concave portion 42, but if the outer covering material 43 is sealed in a state where the air of the portion of the concave portion 42 is not discharged, the core material 44 is deformed in the atmosphere, so that the concave portion 42 The height is shorter. Further, irregularities are also formed on the surface opposite to the surface on which the concave portion 42 is formed. Therefore, the heat insulation performance is lowered. Therefore, the punching machine 50 is formed in advance with a convex surface that matches the shape of the recessed portion 42, and the air of the recessed portion 42 can be discharged after the pressing. In the above manner, as shown in Fig. 6(d), a vacuum heat insulating material 41 is produced.
第7圖為說明本發明實施形態1的邊角46之圖。如前述，藉由熔接外包材43以形成真空隔熱材41等，形成在真空隔熱材41的周圍沒有芯材44的邊角46，以及有塞入芯材44的真空隔熱材本體部47。邊角46是對於隔熱沒有貢獻的部分。例如，若將邊角46就這樣展開著固定在外箱20和內箱30之間，則能夠隔熱的真空隔熱材本體部47的面積就變少了。另外，也會阻礙發泡隔熱材40的填充。 Fig. 7 is a view for explaining a corner 46 of the first embodiment of the present invention. As described above, by laminating the outer covering material 43 to form the vacuum heat insulating material 41 or the like, the corner 46 of the core material 44 is formed around the vacuum heat insulating material 41, and the vacuum heat insulating material body portion is inserted into the core material 44. 47. The corner 46 is a portion that does not contribute to the heat insulation. For example, when the corners 46 are integrally fixed between the outer casing 20 and the inner casing 30, the area of the vacuum heat insulating material main body portion 47 capable of heat insulation is reduced. In addition, the filling of the foamed heat insulating material 40 is also hindered.
第8圖及第9圖為說明本發明實施形態1的折角之圖。第8圖為表示通常的折角之圖。第9圖為表示具有將芯材44的一部沖壓加工後的加工部44a時的折角之圖。本實施形態中，進行了將邊角46折起的折角程序，以使得邊角46不要展開。在此，在具有凹部42之面的相反面的那一側(與內箱30相對向之側)折起邊角46。而且，將已折起之邊角46的外緣46a之部分用固定帶48固定在包著芯材44的真空隔熱材本體部47。固定帶48固定著的部分為固定部。在本實施形態中，用固定帶48固定住外緣46a，但也可以用例如熱熔接的方式來固定。在此，如第9圖所示、尤其是有加工部44a的時候，已折角的部分特別 容易有空氣滯留。 Fig. 8 and Fig. 9 are views for explaining the folding angles according to the first embodiment of the present invention. Fig. 8 is a view showing a normal folding angle. Fig. 9 is a view showing a folding angle when the processed portion 44a is formed by pressing one portion of the core member 44. In the present embodiment, a chamfering program for folding the corners 46 is performed so that the corners 46 are not unfolded. Here, the corner 46 is folded up on the side opposite to the surface having the recess 42 (the side opposite to the inner box 30). Further, a portion of the outer edge 46a of the folded corner 46 is fixed to the vacuum heat insulating material body portion 47 enclosing the core member 44 by a fixing belt 48. The portion to which the fixing band 48 is fixed is a fixing portion. In the present embodiment, the outer edge 46a is fixed by the fixing band 48, but it may be fixed by, for example, heat welding. Here, as shown in Fig. 9, especially when there is a processed portion 44a, the folded portion is particularly It is easy to have air stranded.
第10圖為說明本發明實施形態1的非固定部49之圖。在本實施形態中，在折角的時候，在邊角46的外緣46a當中形成至少一個以上的非固定部49(沒有用固定帶48固定之處)。非固定部49，沒有用固定帶48把折角所形成的邊角46和真空隔熱材本體部47之間完全密封住，而成為空氣的排出口。非固定部49的位置可以為，例如，在真空隔熱材41的長邊方向上的折角部分。再者，如後述，發泡隔熱材40，由填充到外箱20和內箱30之間的空間之路徑來決定為佳。在本實施形態中，形成於真空隔熱材41的長邊方向的中央部分的冰箱100之前面側(門片側)。 Fig. 10 is a view for explaining the non-fixing portion 49 according to the first embodiment of the present invention. In the present embodiment, at the time of folding, at least one non-fixing portion 49 (where the fixing belt 48 is not fixed) is formed in the outer edge 46a of the corner 46. The non-fixed portion 49 is not completely sealed by the fixing band 48 between the corner 46 formed by the chamfer and the vacuum heat insulating material main body portion 47, and serves as an air discharge port. The position of the non-fixed portion 49 may be, for example, a chamfered portion in the longitudinal direction of the vacuum heat insulating material 41. Further, as will be described later, the foamed heat insulating material 40 is preferably determined by the path of the space filled between the outer casing 20 and the inner casing 30. In the present embodiment, the front side (the door side) of the refrigerator 100 is formed in the central portion of the vacuum heat insulating material 41 in the longitudinal direction.
在此，用固定帶48固定住邊角46的外緣46a的固定部變少的話，固定帶48就會容易剝落。另外，做為發泡隔熱材40的材料之聚氨基甲酸酯泡沫塑料(urethane foam)原液進入邊角46和真空隔熱材本體部47之間，會使得原液無法流入必須要填充的地方，而可能產生沒有填充發泡隔熱材40的部分。因此，基本上，非固定部49以少部分為佳。 Here, when the fixing portion of the outer edge 46a of the corner 46 is fixed by the fixing band 48, the fixing band 48 is easily peeled off. In addition, the raw liquid of urethane foam, which is a material of the foamed heat insulating material 40, enters between the corner 46 and the vacuum heat insulating body portion 47, so that the raw liquid cannot flow into the place where it must be filled. However, a portion which is not filled with the foamed heat insulating material 40 may be produced. Therefore, basically, the non-fixed portion 49 is preferably a small portion.
第11圖為表示本發明實施形態1的內箱30之圖。如第11圖所示，在本實施形態中，在內箱30的外側面有凸形狀的墊片34。前述之真空隔熱材41中的非固定部49的位置對應於墊片34的設置位置。因為在非固定部49的地方，邊角46沒有被固定住，所以邊角46有可能會浮起來。若邊角46浮起來的話，有可能會塞住外箱20和內箱30之間，而阻礙發泡隔熱材40的填充。因此，藉由墊片34，壓住非固定部49之處沒有被固定住的 邊角46的展開，而確保外箱20和內箱30之間的空間。而不會阻礙外箱20和內箱30之間的空間中的發泡隔熱材40之填充 Fig. 11 is a view showing the inner box 30 according to the first embodiment of the present invention. As shown in Fig. 11, in the present embodiment, a gasket 34 having a convex shape is provided on the outer surface of the inner casing 30. The position of the non-fixed portion 49 in the aforementioned vacuum heat insulating material 41 corresponds to the position at which the spacer 34 is disposed. Since the corners 46 are not fixed at the non-fixed portion 49, the corners 46 may float. If the corners 46 are floated, there is a possibility that the gap between the outer casing 20 and the inner casing 30 is blocked, and the filling of the foamed heat insulating material 40 is hindered. Therefore, by the spacer 34, the non-fixed portion 49 is not fixed. The corners 46 are unfolded to secure the space between the outer box 20 and the inner box 30. Without impeding the filling of the foamed heat insulating material 40 in the space between the outer box 20 and the inner box 30
在此，墊片34可以事先形成於例如內箱30的金屬模具等上，形成為內箱30的一部分。另外，固定帶可以由發泡苯乙烯等形成，並安裝在內箱30。 Here, the spacer 34 may be formed in advance on, for example, a metal mold of the inner case 30, and formed as a part of the inner case 30. Further, the fixing tape may be formed of foamed styrene or the like and installed in the inner case 30.
第12圖為說明本發明實施形態1之冰箱100中的發泡隔熱材40的形成程序之斜視圖。在本實施形態中，冰箱箱體1a在其背面板22的四個角落有注入口23(23a~23d)。作為發泡隔熱材40的材料之聚氨基甲酸酯泡沫塑料原液注入到注入口23a~23d。 Fig. 12 is a perspective view showing a procedure for forming the foamed heat insulating material 40 in the refrigerator 100 according to the first embodiment of the present invention. In the present embodiment, the refrigerator casing 1a has injection ports 23 (23a to 23d) at four corners of the back panel 22. The polyurethane foam raw material which is a material of the foamed heat insulating material 40 is injected into the injection ports 23a to 23d.
用熱熔接、鋁製的固定帶等，事先將真空隔熱材41暫時固定在外箱20的內面側。使聚氨基甲酸酯泡沫塑料原液發泡，填充發泡隔熱材40時，真空隔熱材41被發泡隔熱材40推壓而固定在外箱20的內面側。 The vacuum heat insulating material 41 is temporarily fixed to the inner surface side of the outer casing 20 by heat welding or a fixing tape made of aluminum or the like. When the polyurethane foam raw material is foamed and the foamed heat insulating material 40 is filled, the vacuum heat insulating material 41 is pressed by the foamed heat insulating material 40 and fixed to the inner surface side of the outer casing 20.
第13圖為表示本發明實施形態1之冰箱100的側面中的發泡隔熱材40的填充路徑的圖。將聚氨基甲酸酯泡沫塑料注入頭70安裝在注入口23a~23d，注入聚氨基甲酸酯泡沫塑料原液。被注入的聚氨基甲酸酯泡沫塑料原液，在冰箱箱體1a的外箱20和內箱30之間的空間中，繞行整個橫寬邊緣側並開始發泡。 Fig. 13 is a view showing a filling path of the foamed heat insulating material 40 in the side surface of the refrigerator 100 according to the first embodiment of the present invention. The polyurethane foam injection head 70 is attached to the injection ports 23a to 23d to inject a polyurethane foam stock solution. The injected polyurethane foam stock solution is wound around the entire widthwise edge side in the space between the outer box 20 and the inner box 30 of the refrigerator cabinet 1a and starts foaming.
如第13圖所示，在冰箱100的側面的發泡隔熱材40填充路徑為，聚氨基甲酸酯泡沫塑料原液從冰箱100的背面側流向前面側之後，在前面側朝向冰箱100的中央部分流動並且發泡。另外，在冰箱100的背面側之發泡隔熱材40填充的路徑 為，聚氨基甲酸酯泡沫塑料原液流向冰箱100的中央部分之後，從冰箱100的背面側向前面側流動並發泡。 As shown in Fig. 13, the foaming heat insulating material 40 on the side surface of the refrigerator 100 is filled in such a manner that the polyurethane foam stock solution flows from the back side of the refrigerator 100 to the front side, and then faces the center of the refrigerator 100 on the front side. Partially flowing and foaming. In addition, the path of filling the foamed heat insulating material 40 on the back side of the refrigerator 100 After the polyurethane foam stock solution flows to the central portion of the refrigerator 100, it flows from the back side to the front side of the refrigerator 100 and is foamed.
例如，在邊角46和真空隔熱材本體部47之間的空氣排出之前，就將發泡隔熱材40填充在非固定部49的話，會使空氣被封在邊角46和真空隔熱材本體部47之間。因此，在發泡隔熱材40最後填充的部分所對應之位置設置非固定部49為佳。因此，在本實施形態中，如前述，在真空隔熱材41的長邊方向的中央部分，在冰箱100的前面側的位置形成非固定部49。此位置是距離注入口23a及注入口23b最遠的位置。形成非固定部49，使得邊角46和真空隔熱材本體部47之間的空氣可以排出。 For example, before the air between the corners 46 and the vacuum heat insulating material body portion 47 is discharged, the foamed heat insulating material 40 is filled in the non-fixed portion 49, so that the air is sealed at the corners 46 and vacuum insulated. Between the material body portions 47. Therefore, it is preferable to provide the non-fixing portion 49 at a position corresponding to the portion where the foamed heat insulating material 40 is finally filled. Therefore, in the present embodiment, as described above, the non-fixed portion 49 is formed at a position on the front side of the refrigerator 100 at the central portion in the longitudinal direction of the vacuum heat insulating material 41. This position is the position farthest from the injection port 23a and the injection port 23b. The non-fixed portion 49 is formed such that air between the corner 46 and the vacuum heat insulating material body portion 47 can be discharged.
第14圖為表示本發明實施形態1的背面側的真空隔熱材41和注入口23之位置關係的圖。例如，基於發泡隔熱材40的填充路徑，固定在背面側的真空隔熱材41，如第14圖所示，在邊角46的2個位置形成非固定部49。在本實施形態的真空隔熱材41中，真空隔熱材41的非固定部49設置為對應於注入口23a和23c、注入口23b和23d的中央部分。 Fig. 14 is a view showing the positional relationship between the vacuum heat insulating material 41 on the back side and the injection port 23 in the first embodiment of the present invention. For example, the vacuum heat insulating material 41 fixed to the back side is formed by the filling path of the foamed heat insulating material 40, and as shown in FIG. 14, the non-fixed portion 49 is formed at two positions of the corners 46. In the vacuum heat insulating material 41 of the present embodiment, the non-fixed portion 49 of the vacuum heat insulating material 41 is provided so as to correspond to the central portions of the injection ports 23a and 23c and the injection ports 23b and 23d.
如上述，依據實施形態1，在折角中形成沒有固定住邊角46的非固定部49，而獲致空氣不會滯留在邊角46和真空隔熱材本體部47之間的真空隔熱材41。因此，能夠獲致冰箱100，使得不會因為冰箱100的運轉，造成滯留的空氣膨脹或收縮等，而使得冰箱100的外箱20及內箱30被加壓而變形。另外，因為空氣不會滯留，所以在填充發泡隔熱材40的時候，能夠減少沒有填充發泡隔熱材40的部分，而能夠獲致隔熱性能優良的 冰箱100。 As described above, according to the first embodiment, the non-fixed portion 49 in which the corners 46 are not fixed is formed in the chamfer, and the vacuum heat insulating material 41 which does not stay in the air between the corners 46 and the vacuum heat insulating material main portion 47 is obtained. . Therefore, the refrigerator 100 can be obtained such that the trapped air does not expand or contract due to the operation of the refrigerator 100, and the outer box 20 and the inner box 30 of the refrigerator 100 are pressurized and deformed. In addition, since the air is not retained, when the foamed heat insulating material 40 is filled, the portion where the foamed heat insulating material 40 is not filled can be reduced, and the heat insulating performance can be improved. Refrigerator 100.
