Description

隔熱箱體及冰箱Insulated boxes and refrigerators

本發明關於冰箱等所具備的隔熱箱體及具備該隔熱箱體的冰箱。The present invention relates to a heat-insulating box provided in a refrigerator and the like, and a refrigerator equipped with the heat-insulating box.

為了進行與周圍的隔熱，在冰箱中以覆蓋儲藏空間的外周的方式設有隔熱箱體。隔熱箱體由外箱、內箱和填充在它們之間的隔熱材料構成。作為隔熱材料，例如使用硬質發泡聚氨酯隔熱材料等發泡隔熱材料。In order to perform heat insulation from the surroundings, the refrigerator is provided with a heat insulating box covering the outer periphery of the storage space. The heat-insulating box is composed of an outer box, an inner box and heat-insulating material filled between them. As the heat insulating material, for example, a foam heat insulating material such as a rigid foamed polyurethane heat insulating material is used.

近年來，為了進一步提高隔熱性能，提出了在隔熱箱內配置真空隔熱材料。In recent years, in order to further improve the thermal insulation performance, it has been proposed to configure vacuum insulation materials in the thermal insulation box.

例如，在日本特開2006-183896號公報中，公開了在隔熱壁內具有真空隔熱材料和發泡隔熱材料的冰箱中，將真空隔熱材料占隔熱壁整體體積的體積率設為規定值以上的冰箱。For example, Japanese Patent Application Laid-Open No. 2006-183896 discloses that in a refrigerator having a vacuum insulation material and a foam insulation material in an insulation wall, the volume ratio of the vacuum insulation material to the entire volume of the insulation wall is set to For refrigerators above the specified value.

通過使用真空隔熱材料，隔熱性能提高，能夠使隔熱箱體的厚度變薄。然，由於隔熱箱體的厚度變薄，隔熱箱體內的發泡隔熱材料流動的空間變窄，發泡隔熱材料難以流動，因此隔熱材料發泡後有可能產生未填充發泡隔熱材料的空隙（void）。By using vacuum insulation materials, the insulation performance is improved and the thickness of the insulation box can be made thinner. However, as the thickness of the insulation box becomes thinner, the space for the foam insulation material to flow in the insulation box becomes narrower, making it difficult for the foam insulation material to flow. Therefore, unfilled foam may occur after the insulation material is foamed. The void in the insulation material.

故，在本發明的一個方式中，其目的在於，提供一種在向隔熱箱體注入發泡隔熱材料時，能夠使得在隔熱箱體內更容易填充發泡隔熱材料的構成。Therefore, in one aspect of the present invention, an object is to provide a structure that can make it easier to fill the heat insulating box with the foamed heat insulating material when injecting the foamed heat insulating material into the heat insulating box.

本發明的一方面涉及的隔熱箱體具有內箱和外箱。該隔熱箱體包括：真空隔熱材料，其配置於該隔熱箱體內；發泡隔熱材料，其被填充於該隔熱箱體內部；以及至少一個注入口，其配置於該隔熱箱體的背面，且注入該發泡隔熱材料的材料。在該隔熱箱體的側面部，與該真空隔熱材料相對的該發泡隔熱材料的厚度小於該真空隔熱材料的厚度的區域比該發泡隔熱材料的厚度為該真空隔熱材料的厚度以上的區域多，在該內箱的側面部設置有對配置於該隔熱箱體的箱內的擱板進行支撐的支撐部，該支撐部的縱向寬度以及橫向寬度大於該發泡隔熱材料的厚度。One aspect of the present invention relates to a heat-insulating box having an inner box and an outer box. The heat insulating box includes: vacuum heat insulating material, which is arranged in the heat insulating box; foam heat insulating material, which is filled inside the heat insulating box; and at least one injection port, which is arranged in the heat insulating box. The back of the box is filled with foam insulation material. On the side portion of the heat insulating box, an area in which the thickness of the foamed heat insulating material opposite to the vacuum heat insulating material is smaller than the thickness of the vacuum heat insulating material is smaller than the thickness of the foamed heat insulating material. There are many areas above the thickness of the material. A support portion is provided on the side portion of the inner box to support the shelf arranged in the insulating box. The longitudinal width and lateral width of the support portion are larger than that of the foam. The thickness of the insulation material.

根據本發明的一個方面的隔熱箱體，在注入發泡隔熱材料時，能夠使得在隔熱箱體內更容易填充發泡隔熱材料。According to the heat-insulating box according to one aspect of the present invention, when the foamed heat-insulating material is injected, the foamed heat-insulating material can be filled more easily in the heat-insulating box.

In the following description, the same components are given the same reference numerals. Their names and functions are also the same. Therefore, detailed descriptions about them will not be repeated.

＜第一實施方式＞ （冰箱的整體構成） 首先，說明根據第一實施方式的冰箱10的整體構成。圖1示出冰箱1的內部構成。 <First Embodiment> (The overall composition of the refrigerator) First, the overall structure of the refrigerator 10 according to the first embodiment will be described. FIG. 1 shows the internal structure of the refrigerator 1 .

如圖1所示，冰箱1在上段具備冷藏室11、在中段具備蔬菜室12、以及在下段具備冷凍室13等。冷藏室11設有冷藏室門11a。蔬菜室12設有蔬菜室門12a。冷凍室13設有冷凍室門13a。As shown in FIG. 1 , the refrigerator 1 includes a refrigerator compartment 11 in an upper section, a vegetable compartment 12 in a middle section, a freezer compartment 13 in a lower section, and the like.

The freezing chamber 13 is provided with a freezing chamber door 13a.

如上所述，根據本實施方式的冰箱1被劃分為上段部、中段部以及下段部，並設有各儲藏空間。在各儲藏空間之間設有分隔部。更具體而言，在上段的冷藏室11和中段的蔬菜室12之間設有第一分隔部54。再者，在中段的蔬菜室12和下段的冷凍室13之間設有第二分隔部55。此外，對於各儲藏空間的配置位置並不限定於此。As described above, the refrigerator 1 according to this embodiment is divided into the upper section, the middle section, and the lower section, and each storage space is provided. A partition is provided between each storage space. More specifically, the first partition 54 is provided between the upper refrigerator compartment 11 and the middle vegetable compartment 12 . Furthermore, a second partition 55 is provided between the vegetable compartment 12 in the middle section and the freezing compartment 13 in the lower section. In addition, the arrangement position of each storage space is not limited to this.

在本實施方式中，將設有門的面稱為冰箱的正面或前表面。並且，以前表面為基準，基於在通常狀態下設置冰箱1時所存在的位置，將冰箱1的各面設為上表面、側面、背面以及底面。再者，在將冰箱1載置於設置面上的狀態下，將冰箱1的上下的方向稱為冰箱1（或者隔熱箱體50等）的上下方向。再者，在將冰箱1載置於設置面上的狀態下，將從正面觀察冰箱1時的前後的方向稱為冰箱1（或者隔熱箱體50等）的前後方向。In this embodiment, the surface provided with the door is called the front surface or the front surface of the refrigerator. Furthermore, with the front surface as a reference, each surface of the refrigerator 1 is defined as an upper surface, a side surface, a back surface, and a bottom surface based on the position where the refrigerator 1 exists when the refrigerator 1 is installed in a normal state. In addition, in the state where the refrigerator 1 is placed on the installation surface, the up-and-down direction of the refrigerator 1 is called the up-and-down direction of the refrigerator 1 (or the heat insulation box 50, etc.). In addition, when the refrigerator 1 is placed on the installation surface, the front-to-back direction when viewing the refrigerator 1 from the front is called the front-to-back direction of the refrigerator 1 (or the heat insulation box 50, etc.).

在冰箱1的內部設有製冷循環。製冷循環構成為經由製冷劑流通的製冷劑管（製冷劑流路），連接壓縮機31、冷凝器（未圖示）、膨脹器（未圖示）和冷卻器（蒸發器）32。A refrigeration cycle is provided inside the refrigerator 1 . The refrigeration cycle is configured by connecting a compressor 31, a condenser (not shown), an expander (not shown), and a cooler (evaporator) 32 via a refrigerant pipe (refrigerant flow path) through which refrigerant flows.

再者，在冰箱1的內部設有控制部（未圖示）。該控制部對製冷循環的運轉進行控制。即，控制部通過驅動壓縮機31，開始製冷循環的運轉，製冷劑在循環內流通。如圖1所示，壓縮機31配置於設於冰箱1的底部的背面側的機械室30內。Furthermore, a control unit (not shown) is provided inside the refrigerator 1 . This control unit controls the operation of the refrigeration cycle. That is, the control unit drives the compressor 31 to start the operation of the refrigeration cycle, and the refrigerant circulates in the cycle. As shown in FIG. 1 , the compressor 31 is disposed in the machine room 30 provided on the back side of the bottom of the refrigerator 1 .

冷卻器32配置於設於冰箱1的背面側的冷卻室35內。在冷卻室35內，除了冷卻器32以外，還具備冷卻風扇33等。冷卻風扇33是為了使空氣在冷卻室35與各儲藏空間之間循環而設置的。冷卻室35與冷氣管道41連通。冷氣管道41成為用於將在冷卻室35生成的冷氣向冷藏室11等供給的冷氣通路。The cooler 32 is arranged in the cooling chamber 35 provided on the back side of the refrigerator 1 . In addition to the cooler 32, the cooling chamber 35 is provided with a cooling fan 33 and the like. The cooling fan 33 is provided to circulate air between the cooling chamber 35 and each storage space. The cooling chamber 35 is connected to the cold air duct 41 . The cold air duct 41 serves as a cold air passage for supplying the cold air generated in the cooling chamber 35 to the refrigerator compartment 11 and the like.

（隔熱箱體的構成） 在冰箱1中，作為用於將各儲藏空間從周圍隔熱的隔熱結構，設有隔熱箱體50。圖2示出從正面側（間口部50e側）觀察隔熱箱體50時的外觀。隔熱箱體50以覆蓋冰箱1的外周的方式設置。隔熱箱體50主要由上表面部、側面部50b、背面部50c以及底面部構成。隔熱箱體50的正面側為開口的間口部50e。 (Construction of heat insulation box) The refrigerator 1 is provided with a heat insulating box 50 as a heat insulating structure for insulating each storage space from the surroundings. FIG. 2 shows the appearance of the heat insulating box 50 when viewed from the front side (the side of the opening 50e). The heat insulating box 50 is provided to cover the outer periphery of the refrigerator 1 . The heat insulation box 50 is mainly composed of an upper surface part, a side part 50b, a back part 50c, and a bottom part. The front side of the heat insulating box 50 is an open mouth portion 50e.

如圖1所示，隔熱箱體50主要包括外箱60、內箱70、真空隔熱材料51和發泡隔熱材料52和至少一個分隔部（例如第一分隔部54及第二分隔部55）。As shown in FIG. 1 , the thermal insulation box 50 mainly includes an outer box 60 , an inner box 70 , a vacuum insulation material 51 and a foam insulation material 52 and at least one partition (such as a first partition 54 and a second partition 55).

外箱60形成隔熱箱體50的外周面。外箱60主要由上表面部60a、側面部60b、背面部60c以及底面部構成。內箱70形成隔熱箱體50的內周面。內箱70主要由上表面部、側面部70b、背面部70c以及底面部70d構成。內箱70形成儲藏空間（例如，冷藏室11、蔬菜室12、冷凍室13）的內壁和冷卻室35的後壁。The outer box 60 forms the outer peripheral surface of the heat insulating box 50 . The outer box 60 is mainly composed of an upper surface part 60a, a side part 60b, a back part 60c, and a bottom part. The inner box 70 forms the inner peripheral surface of the heat insulating box 50 . The inner box 70 is mainly composed of an upper surface part, a side part 70b, a back part 70c, and a bottom part 70d. The inner box 70 forms the inner wall of the storage space (for example, the refrigerator compartment 11 , the vegetable compartment 12 , and the freezing compartment 13 ) and the rear wall of the cooling chamber 35 .

由內箱70形成的隔熱箱體50的內部由至少一個分隔部分隔為多個空間。在本實施方式中，包括第一分隔部54和第二分隔部55這兩個分隔部。第一分隔部54配置於冷藏室11和蔬菜室12之間。第二分隔部55配置於蔬菜室12和冷凍室13之間。The interior of the heat insulating box 50 formed by the inner box 70 is divided into a plurality of spaces by at least one partition. In this embodiment, two partition parts, a first partition part 54 and a second partition part 55 are included. The first partition 54 is arranged between the refrigerator compartment 11 and the vegetable compartment 12 . The second partition 55 is arranged between the vegetable compartment 12 and the freezing compartment 13 .

此外，在隔熱箱體50的底部的背面側形成有用於配置機械室30的空間。機械室30配置於隔熱箱體50的外側。這是因為，通過壓縮機31運轉，機械室30內的溫度上升。機械室30主要由構成外箱60的底面部的底板62劃分。In addition, a space for arranging the machine room 30 is formed on the back side of the bottom of the heat insulating box 50 . The machine room 30 is arranged outside the heat insulation box 50 . This is because the temperature in the machine room 30 rises due to the operation of the compressor 31 . The machine room 30 is mainly divided by the bottom plate 62 constituting the bottom surface of the outer box 60 .

這樣，機械室30和冷凍室13被隔熱箱體50隔離。故，能夠抑制在機械室30內產生的熱流入冷凍室13。In this way, the machine room 30 and the freezing room 13 are isolated by the heat insulating box 50 . Therefore, the heat generated in the machine room 30 can be suppressed from flowing into the freezing chamber 13 .

真空隔熱材料51和發泡隔熱材料52設置在外箱60與內箱70之間的空間內。真空隔熱材料51也被稱為VIP，是薄片狀或板狀的隔熱材料。真空隔熱材料51例如分別配置於冰箱1的側面、上表面、底面和背面等。在圖1中，省略了配置於冰箱1的底面上的真空隔熱材料的圖示。如圖1等所示，真空隔熱材料51配置於隔熱箱體50內的外箱60側。The vacuum insulation material 51 and the foam insulation material 52 are provided in the space between the outer box 60 and the inner box 70 . The vacuum heat insulating material 51 is also called VIP and is a sheet-shaped or plate-shaped heat insulating material. For example, the vacuum heat insulating materials 51 are respectively arranged on the side surfaces, the upper surface, the bottom surface, the back surface, etc. of the refrigerator 1 . In FIG. 1 , illustration of the vacuum heat insulating material arranged on the bottom surface of the refrigerator 1 is omitted. As shown in FIG. 1 etc., the vacuum heat insulating material 51 is arrange|positioned in the heat insulation box 50 on the outer box 60 side.

發泡隔熱材料52例如可以由發泡聚氨酯（也稱為硬質聚氨酯泡沫）等形成。發泡隔熱材料52也填充在分隔作為冷藏儲藏空間的蔬菜室12和作為冷凍儲藏空間的冷凍室13的第二分隔部55的內部。在本實施方式中，將也作為冷藏儲藏空間的冷藏室11和蔬菜室12分隔的第一分隔部54的內部未由發泡隔熱材料52填充。在第一分隔部54的內部，也可以配置與發泡隔熱材料52不同的隔熱材料。再者，在另一實施方式中，也可以在第一分隔部54的內部填充發泡隔熱材料52。The foamed heat insulating material 52 may be formed of, for example, foamed polyurethane (also called rigid polyurethane foam) or the like. The foamed heat insulating material 52 is also filled in the second partition part 55 that partitions the vegetable compartment 12 as a refrigerated storage space and the freezing compartment 13 as a frozen storage space. In this embodiment, the inside of the first partition 54 that partitions the refrigerator compartment 11 and the vegetable compartment 12 which are also refrigerated storage spaces is not filled with the foamed heat insulating material 52 . A heat insulating material different from the foam heat insulating material 52 may be disposed inside the first partition 54 . Furthermore, in another embodiment, the inside of the first partition 54 may be filled with the foamed heat insulating material 52 .

發泡隔熱材料52將液狀的發泡聚氨酯材料（也稱為發泡隔熱材料的材料、隔熱材料）注入隔熱箱體50內，使材料在隔熱箱體50內發泡，從而填充於隔熱箱體50內。外箱60的背面部60c設有注入隔熱材料的注入口58（參照圖5）。在本實施方式中，在背面部60c的左側的端部附近設有兩個注入口58，在背面部60c的右側的端部附近設有兩個注入口58，設有共計四個注入口58。然，注入口58的個數並不限定於此。The foamed heat insulating material 52 injects liquid foamed polyurethane material (also called foamed heat insulating material, heat insulating material) into the heat insulating box 50, so that the material foams in the heat insulating box 50. Thereby, the heat insulation box 50 is filled. The back portion 60 c of the outer box 60 is provided with an injection port 58 for injecting the heat insulating material (see FIG. 5 ). In this embodiment, two injection ports 58 are provided near the left end of the back portion 60c, and two injection ports 58 are provided near the right end of the back portion 60c. A total of four injection ports 58 are provided. . However, the number of injection ports 58 is not limited to this.

圖2示出向隔熱箱體50注入發泡聚氨酯材料時的隔熱箱體50。在向隔熱箱體50注入發泡聚氨酯材料時，如圖2所示，僅將第二分隔部55安裝在隔熱箱體50的箱內。由此，當從注入口58注入發泡隔熱材料時，經由設於內箱70與第二分隔部55之間的聚氨酯流入口，在第二分隔部55的內部也填充發泡隔熱材料52。FIG. 2 shows the heat insulating box 50 when the foamed polyurethane material is injected into the heat insulating box 50 . When the foamed polyurethane material is injected into the heat insulating box 50 , as shown in FIG. 2 , only the second partition 55 is installed inside the heat insulating box 50 . Accordingly, when the foamed heat insulating material is injected from the injection port 58 , the foamed heat insulating material is also filled into the inside of the second partition 55 via the polyurethane inlet provided between the inner box 70 and the second partition 55 52.

（關於隔熱箱體的側壁厚度和真空隔熱材料的厚度） 在近年來的冰箱中，以確保更大的箱內空間等為目的，希望隔熱箱體50的側壁薄型化。故，在本實施方式中，實現隔熱箱體50的各面（例如側面部50b）的壁的薄型化。 (Regarding the thickness of the side walls of the insulated box and the thickness of the vacuum insulation material) In recent refrigerators, for the purpose of ensuring a larger interior space, it is desired to make the side wall of the heat insulating box 50 thinner. Therefore, in this embodiment, the wall thickness of each surface (for example, the side part 50b) of the heat insulation box 50 is made thin.

圖4示意性地示出隔熱箱體50的側壁內的構成。圖4是示出圖3所示的隔熱箱體50的A-A線部分的剖面圖。再者，在圖4中，放大並示出隔熱箱體50的一部分（由虛線框包圍的部分）。FIG. 4 schematically shows the structure within the side wall of the heat insulating box 50 . FIG. 4 is a cross-sectional view showing the A-A line portion of the heat insulating box 50 shown in FIG. 3 . In addition, in FIG. 4 , a part of the heat insulating box 50 (a portion surrounded by a dotted frame) is enlarged and shown.

本實施方式涉及的隔熱箱體50的側面部50b的平均厚度例如為25mm以上35mm以下。並且，在隔熱箱體50的側面部50b中，與真空隔熱材料51相對的發泡隔熱材料52的厚度T2小於真空隔熱材料51的厚度T1的區域比厚度T2為真空隔熱材料51的厚度T1以上的區域多。The average thickness of the side portion 50b of the heat insulating box 50 according to this embodiment is, for example, 25 mm or more and 35 mm or less. Furthermore, in the side portion 50b of the heat insulating box 50, the area where the thickness T2 of the foamed heat insulating material 52 facing the vacuum heat insulating material 51 is smaller than the thickness T1 of the vacuum heat insulating material 51 is smaller than the thickness T2 of the vacuum heat insulating material. There are many areas above thickness T1 of 51.

配置於側面部50b的真空隔熱材料51的厚度T1在真空隔熱材料的整個區域大致固定。在一個示例中，真空隔熱材料51的厚度T1設定為10mm以上30mm以下，優選地，設定為15mm以上25mm以下。The thickness T1 of the vacuum heat insulating material 51 arranged on the side part 50b is substantially constant over the entire area of the vacuum heat insulating material. In one example, the thickness T1 of the vacuum insulation material 51 is set to 10 mm or more and 30 mm or less, preferably, it is set to 15 mm or more and 25 mm or less.

另一方面，發泡隔熱材料52的厚度T2根據隔熱箱體50的外形（尤其是內箱70的形狀）在各部分不同。如上所述，在隔熱箱體50的側面部50b，在真空隔熱材料51存在的區域的大部分、至少一半以上，厚度T1大於T2。故，側面部50b的真空隔熱材料51存在的面積的大部分的發泡隔熱材料52的厚度T2例如設定為5mm以上15mm以下，優選地，設定為8mm以上13mm以下。On the other hand, the thickness T2 of the foamed heat insulating material 52 differs in each part according to the outer shape of the heat insulating box 50 (especially the shape of the inner box 70). As described above, in the side portion 50b of the heat insulating box 50, the thickness T1 is larger than T2 in most, at least half, of the area where the vacuum heat insulating material 51 exists. Therefore, the thickness T2 of the foam insulation material 52 covering most of the area where the vacuum insulation material 51 exists in the side portion 50b is set to, for example, 5 mm or more and 15 mm or less, preferably, 8 mm or more and 13 mm or less.

在一個示例中，真空隔熱材料51的厚度T1可以是泡沫隔熱材料52的厚度T2的約2倍。這樣，通過在側面部50b提高真空隔熱材料51的比例，能夠進一步減小作為側面部50b整體的厚度。In one example, the thickness T1 of the vacuum insulation 51 may be approximately 2 times the thickness T2 of the foam insulation 52 . In this way, by increasing the proportion of the vacuum heat insulating material 51 in the side portion 50b, the thickness of the entire side portion 50b can be further reduced.

再者，配置於隔熱箱體50的側面部50b以外的面部（即，上表面部、背面部50c、底面部）上的真空隔熱材料的厚度可以與厚度T1相同，也可以不同。再者，隔熱箱體50的側面部50b以外的面部（即，上表面部、背面部50c、底面部）中的發泡隔熱材料52的厚度可以是配置於該面部的真空隔熱材料51的厚度以上，也可以是真空隔熱材料51的厚度以下。In addition, the thickness of the vacuum heat insulating material arranged on the surface parts other than the side part 50b of the heat insulating box 50 (that is, the upper surface part, the back part 50c, and the bottom surface part) may be the same as the thickness T1, or may be different. Furthermore, the thickness of the foamed heat insulating material 52 in the surface portion other than the side portion 50b of the heat insulating box 50 (that is, the upper surface portion, the back portion 50c, and the bottom portion) may be equal to the thickness of the vacuum heat insulating material disposed on the surface portion. The thickness of the vacuum heat insulating material 51 may be greater than or equal to the thickness of the vacuum heat insulating material 51 .

例如，在背面部50c中，配置於背面部50c的發泡隔熱材料52的厚度也可以為配置於背面部50c的真空隔熱材料51的厚度以上。在背面部有與冷卻器32連接的製冷循環的配管、電氣配線等通過的傾向，為了固定這些配管、配線等，並進一步確保隔熱性，配置於背面部50c的發泡隔熱材料52的厚度優選為具有一定以上的厚度。再者，儘管背面部50c往往是最後被填充發泡隔熱材料52的地方，而且考慮到與其他部位相比隔熱材料的固化正在進行，但通過加厚配置於背面部50c的發泡隔熱材料52的厚度，將容易確保隔熱材料的流動性。For example, in the back surface part 50c, the thickness of the foam heat insulating material 52 arrange|positioned in the back surface part 50c may be greater than the thickness of the vacuum heat insulating material 51 arrange|positioned in the back surface part 50c. Pipes, electrical wiring, etc. of the refrigeration cycle connected to the cooler 32 tend to pass through the back part. In order to fix these pipes, wiring, etc. and further ensure thermal insulation, the foam heat insulating material 52 arranged on the back part 50c is The thickness is preferably a certain thickness or more. Furthermore, although the back part 50c is often the last place to be filled with the foam insulation material 52, and considering that the curing of the heat insulation material is progressing compared with other parts, by thickening the foam insulation disposed in the back part 50c, The thickness of the thermal material 52 will easily ensure the fluidity of the insulating material.

（隔熱箱體的製造方法） 接著，對隔熱箱體50的製造方法進行說明。圖5示出向隔熱箱體50注入隔熱材料的情況。 (Method of manufacturing heat-insulating box) Next, a method of manufacturing the heat insulating box 50 will be described. FIG. 5 shows the state of injecting heat insulating material into the heat insulating box 50 .

首先，在外箱60的各面部（具體而言，上表面部、側面部60b以及背面部60c等）的內側面的規定位置，安裝真空隔熱材料51、散熱管（未圖示）等部件。再者，在內箱70的規定位置安裝箱內電裝單元、各種配線等部件。First, components such as the vacuum heat insulating material 51 and the heat dissipation pipe (not shown) are installed at predetermined positions on the inner surfaces of each surface of the outer box 60 (specifically, the upper surface, side surfaces 60b, and back 60c). Furthermore, in-box electrical components, various wiring and other components are installed at predetermined positions of the inner box 70 .

接著，以覆蓋內箱70的外周的方式安裝外箱60的各面部。由此，形成隔熱箱體50的外形。Next, each surface part of the outer box 60 is attached so as to cover the outer periphery of the inner box 70 . Thereby, the outer shape of the heat insulation box 50 is formed.

然後，在隔熱箱體50的背面部50c朝上的狀態下，從形成於外箱60的背面部60c的注入口58注入液體狀的發泡隔熱材料的材料（發泡聚氨酯材料）。此時，注入口58中***有隔熱材料的注入裝置的注入噴嘴91（參照圖5）。從注入噴嘴91向隔熱箱體50內噴出的發泡隔熱材料的材料在外箱60與內箱70之間的空間內從前面側（間口部50e側）向背面側依次發泡，一邊增加體積一邊填充。發泡的隔熱材料隨後固化。Then, with the back surface 50 c of the heat insulating box 50 facing upward, a liquid foam heat insulating material (foamed polyurethane material) is injected from the injection port 58 formed in the back surface 60 c of the outer box 60 . At this time, the injection nozzle 91 of the heat insulating material injection device is inserted into the injection port 58 (see FIG. 5 ). The foamed heat insulating material sprayed from the injection nozzle 91 into the heat insulating box 50 is foamed in the space between the outer box 60 and the inner box 70 in an increasing order from the front side (the gap portion 50e side) to the back side. Volume side filling. The foamed insulation is then cured.

即，當在隔熱箱體50的背面部60c朝上的狀態下從各注入口58注入隔熱材料時，隔熱材料因重力而通過隔熱箱體50內的側面部50b及上表面部等，向位於最下方的間口部50e流下。That is, when the heat insulating material is injected from each injection port 58 with the back portion 60c of the heat insulating box 50 facing upward, the heat insulating material passes through the side portion 50b and the upper surface portion in the heat insulating box 50 due to gravity. etc., and flows down toward the lowermost intermouth portion 50e.

如上所述，在本實施方式中，在隔熱箱體50的側面部50b的大部分區域中，真空隔熱材料51的厚度T1大於發泡隔熱材料的厚度T2。隔熱箱體50的側壁的厚度變薄，從而隔熱材料在側壁內流動的空間變窄，隔熱材料變得難以流動。當在隔熱箱體50的內部設有真空隔熱材料51時，隔熱材料的流動空間變得更窄。由此，在隔熱箱體50內，注入的隔熱材料在發泡後，產生未填充發泡隔熱材料的空隙（Void）的可能性提高。As described above, in the present embodiment, the thickness T1 of the vacuum heat insulating material 51 is larger than the thickness T2 of the foam heat insulating material in most areas of the side portion 50b of the heat insulating box 50. The thickness of the side wall of the heat insulating box 50 becomes thinner, so that the space for the heat insulating material to flow in the side wall becomes narrower, making it difficult for the heat insulating material to flow. When the vacuum insulation material 51 is provided inside the insulation box 50, the flow space of the insulation material becomes narrower. This increases the possibility that voids (voids) not filled with the foamed heat insulating material will be generated in the heat insulating box 50 after the injected heat insulating material is foamed.

例如，如果在注入液體狀的發泡隔熱材料時碰到隔熱箱體50內的壁面，則在該部位部分地開始發泡，之後在隔熱材料從隔熱箱體50的前面側一邊發泡一邊填充時，該部分地發泡的部位成為障礙物，有可能填充不均勻。具體而言，在注入發泡隔熱材料時，在注入口58的正下方及其附近的隔熱箱體50的側面部50b內，在更早的階段隔熱材料的發泡開始，因此容易產生妨礙隔熱材料的流動性的障礙物。For example, if the liquid foamed heat insulating material hits the wall surface inside the heat insulating box 50 when injecting it, foaming begins partially at that location, and then the heat insulating material moves from the front side of the heat insulating box 50 to When filling while foaming, the partially foamed area may become an obstacle and the filling may be uneven. Specifically, when the foamed heat insulating material is injected, foaming of the heat insulating material starts at an earlier stage in the side portion 50b of the heat insulating box 50 immediately below the injection port 58 and in the vicinity, so it is easy to Create obstructions that impede the flow of insulation.

（隔熱箱體的擱板支撐部的構成） 故，在本實施方式中，為了促進發泡隔熱材料的流入，對能夠配置於從正面觀察時與注入口58重疊的位置的內箱70的側面部70b進行了研究。以下，對該結構進行說明。 (Construction of the shelf support part of the heat-insulating box) Therefore, in this embodiment, in order to promote the inflow of the foam insulation material, the side part 70b of the inner box 70 which can be arrange|positioned in the position which overlaps the injection port 58 when viewed from the front was considered. This structure will be described below.

圖6示出隔熱箱體50的冷藏室11左側的側面部50b的構成。在圖7~圖9中，示意性地示出隔熱箱體50的冷藏室11局部的縱剖面的構成。圖7是示出與圖3的A-A線對應的位置中的隔熱箱體50的剖面圖。圖8是示出與圖3的B-B線對應的位置中的隔熱箱體50的剖面圖。圖9是示出與圖3的C-C線對應的位置中的隔熱箱體50的剖面圖。再者，圖7至圖9中也示出將各圖所示的隔熱箱體50的一部分(用虛線框包圍的部分)放大的剖面圖。FIG. 6 shows the structure of the side portion 50b on the left side of the refrigerating compartment 11 of the heat insulating box 50. FIGS. 7 to 9 schematically illustrate a partial longitudinal cross-sectional structure of the refrigerating compartment 11 of the heat insulating box 50 . FIG. 7 is a cross-sectional view showing the heat insulating box 50 at a position corresponding to line A-A in FIG. 3 . FIG. 8 is a cross-sectional view showing the heat insulating box 50 at a position corresponding to line B-B in FIG. 3 . FIG. 9 is a cross-sectional view showing the heat insulating box 50 at a position corresponding to line C-C in FIG. 3 . Furthermore, FIGS. 7 to 9 also show an enlarged cross-sectional view of a part of the heat insulating box 50 shown in each figure (a portion surrounded by a dotted frame).

圖10示出隔熱箱體50的側面部50b與注入口58的位置關係。圖10是在與圖3的C-C線對應的位置的隔熱箱體50的剖面圖中圖示了注入口58的配置位置的圖。FIG. 10 shows the positional relationship between the side portion 50b of the heat insulating box 50 and the injection port 58. FIG. 10 is a diagram illustrating the arrangement position of the injection port 58 in a cross-sectional view of the heat insulating box 50 at a position corresponding to line C-C in FIG. 3 .

如圖2等所示，由內箱70形成的箱內的內壁主要由上表面部、側面部70b、背面部70c及底面部70d構成。在側面部70b具有局部地在箱內側***的部位。As shown in FIG. 2 etc., the inner wall in the box formed by the inner box 70 mainly consists of an upper surface part, a side part 70b, a back part 70c, and a bottom part 70d. The side portion 70b has a portion that is partially raised inside the box.

例如，在形成冷藏室11的箱內的側面部70b的上方部分，作為這樣***的部分，設有多個擱板支撐部。擱板支撐部保持用於劃分冷藏室11內的擱板（未圖示）。在本實施方式中，從冷藏室11的上方側依次設有第一擱板支撐部21a以及第二擱板支撐部21b等多個擱板支撐部。各擱板支撐部分別左右對稱地配置於左側的側面部70b和右側的側面部70b。For example, a plurality of shelf support portions are provided as such raised portions in an upper portion of the side portion 70b in the box forming the refrigerating compartment 11. The shelf support portion holds shelves (not shown) for dividing the inside of the refrigerator compartment 11 . In this embodiment, a plurality of shelf support parts such as the first shelf support part 21a and the second shelf support part 21b are provided in order from the upper side of the refrigerator compartment 11. Each shelf support part is arranged left and right symmetrically on the left side surface part 70b and the right side surface part 70b respectively.

再者，在形成冷凍室13的箱內的側面部70b的下方部分，作為這樣***的部分，設有收納容器保持部26。收納容器保持部26保持配置於冷凍室13內的收納容器（未圖示）。收納容器保持部26分別左右對稱地配置於左側的側面部70b和右側的側面部70b。In addition, the storage container holding part 26 is provided as such a raised part in the lower part of the side part 70b in the box which forms the freezing chamber 13. The storage container holding part 26 holds the storage container (not shown) arrange|positioned in the freezing chamber 13. The storage container holding portion 26 is arranged bilaterally symmetrically on the left side surface portion 70b and the right side surface portion 70b.

在本實施方式中，將供注入噴嘴91***的注入口58的配置位置規定為在正面觀察時與上述的側面部70b的***的部分重疊（參照圖10）。由此，在注入液體狀的發泡隔熱材料時，能夠抑制碰到隔熱箱體50內的壁面，並且能夠使液體狀的發泡隔熱材料均勻地遍佈隔熱箱體50的開口側。故，在薄壁化的隔熱箱體50中也能夠抑制注入的隔熱材料的流動性的降低，並且能夠使發泡隔熱材料更容易填充到隔熱箱體內。In this embodiment, the placement position of the injection port 58 into which the injection nozzle 91 is inserted is defined so as to overlap with the raised portion of the side portion 70 b described above when viewed from the front (see FIG. 10 ). Accordingly, when the liquid foam heat insulating material is injected, it is possible to prevent the liquid foam heat insulating material from hitting the wall surface inside the heat insulating box 50 and to spread the liquid foam heat insulating material evenly across the opening side of the heat insulating box 50 . Therefore, even in the thinned heat insulating box 50, it is possible to suppress a decrease in the fluidity of the injected heat insulating material, and to make it easier to fill the foamed heat insulating material into the heat insulating box.

具體而言，隔熱箱體50的上方側的注入口58的配置位置與設於側面部70b的第二隔板支撐部（支撐部）21b的配置位置對應。即，第二隔板支撐部21b設於在正面觀察（或背面觀察）時與設於背面部60c的注入口58重疊的位置。由此，能夠確保從***注入口58的注入噴嘴91注入的隔熱材料的注入路徑。再者，能夠確保由於發泡而膨脹的隔熱材料的佔有區域。Specifically, the placement position of the injection port 58 on the upper side of the heat insulating box 50 corresponds to the placement position of the second partition plate support portion (support portion) 21 b provided in the side portion 70 b. That is, the second partition support portion 21 b is provided at a position that overlaps the injection port 58 provided in the back portion 60 c when viewed from the front (or viewed from the back). This ensures an injection path for the heat insulating material injected from the injection nozzle 91 inserted into the injection port 58 . Furthermore, the area occupied by the heat insulating material expanded by foaming can be ensured.

再者，隔熱箱體50的下方側的注入口58的配置位置與設於側面部70b的收納容器保持部26的配置位置對應。即，收納容器保持部26在正面觀察（或背面觀察）時設於與被設於背面部60c的注入口58重疊的位置。由此，能夠確保從***注入口58的注入噴嘴91注入的隔熱材料的注入路徑。再者，能夠確保由於發泡而膨脹的隔熱材料的佔有區域。In addition, the arrangement position of the pouring port 58 on the lower side of the heat insulating box 50 corresponds to the arrangement position of the storage container holding part 26 provided in the side part 70b. That is, the storage container holding part 26 is provided in the position which overlaps with the injection port 58 provided in the back part 60c in front view (or back view). This ensures an injection path for the heat insulating material injected from the injection nozzle 91 inserted into the injection port 58 . Furthermore, the area occupied by the heat insulating material expanded by foaming can be ensured.

第二擱板支撐部21b由沿前後方向延伸的多個突起部構成。背面側的兩個突起部具有主體部22和後方伸出部23。主體部22是沿前後方向延伸的細長突起。後方伸出部23位於主體部22的後方及下方，且以擴張第二擱板支撐部21b的內徑的方式設置。The second shelf support part 21b is composed of a plurality of protrusions extending in the front-rear direction. The two protruding parts on the back side have a main body part 22 and a rear extension part 23. The main body portion 22 is an elongated protrusion extending in the front-rear direction. The rear extension part 23 is located behind and below the main body part 22, and is provided so as to expand the inner diameter of the second shelf support part 21b.

再者，在第一擱板支撐部21a上也設有與第二擱板支撐部21b同樣的突起部。即，構成第一擱板支撐部21a的多個突起部中的上方後方側的突起部具有主體部22和後方伸出部23。In addition, the first shelf support part 21a is also provided with the same protrusion part as the second shelf support part 21b. That is, among the plurality of protrusions constituting the first shelf support part 21 a , the protrusion part on the upper rear side has the main body part 22 and the rear extension part 23 .

注入口58期望設置在與具有後方伸出部23的突起部中的任一個在正面觀察時重疊的位置。由此，能夠確保從注入口58注入的隔熱材料的注入路徑，並且能夠確保因發泡而膨脹的隔熱材料的佔有區域。The injection port 58 is desirably provided at a position that overlaps any of the protruding portions having the rear protruding portion 23 when viewed from the front. Thereby, the injection path of the heat insulating material injected from the injection port 58 can be ensured, and the occupied area of the heat insulating material expanded by foaming can be ensured.

在本實施方式中，上方側的注入口58被配置為與第二擱板支撐部21b的下側的突起部24對應。而且，第二擱板支撐部21b的下側的突起部24的內徑大於隔熱箱體50的側面部50b的發泡隔熱材料的厚度T2。In this embodiment, the upper injection port 58 is arranged to correspond to the lower protrusion 24 of the second shelf support part 21 b. Furthermore, the inner diameter of the lower protruding portion 24 of the second shelf support portion 21 b is larger than the thickness T2 of the foamed heat insulating material of the side portion 50 b of the heat insulating box 50 .

此處，突起部24的內徑是指突起部24的縱向寬度W5及橫向寬度W6（參照圖8及圖9）。橫向寬度W6是突起部24中橫向寬度最大的部位的橫向寬度。縱向寬度W5根據突起部24的前後方向的位置而不同。例如，將圖3的B-B線的位置處的突起部24的縱向寬度設為W5b，將圖3的C-C線的位置處的突起部的縱向寬度設為W5c。Here, the inner diameter of the protrusion 24 refers to the longitudinal width W5 and the transverse width W6 of the protrusion 24 (see FIGS. 8 and 9 ). The lateral width W6 is the lateral width of the portion of the protrusion 24 with the largest lateral width. The longitudinal width W5 differs depending on the position of the protrusion 24 in the front-rear direction. For example, let the vertical width of the protrusion 24 at the position of line B-B in FIG. 3 be W5b, and let the vertical width of the protrusion 24 at the position of line C-C in FIG. 3 be W5c.

故，突起部24的內徑大於發泡隔熱材料的厚度T2意味著突起部24的縱向寬度W5（具體而言，縱向寬度W5b或W5c）及橫向寬度W6大於發泡隔熱材料的厚度T2。即，W5＞T2，並且W6＞T2。Therefore, the inner diameter of the protruding portion 24 is larger than the thickness T2 of the foamed thermal insulation material, which means that the longitudinal width W5 (specifically, the longitudinal width W5b or W5c) and the transverse width W6 of the protruding portion 24 are larger than the thickness T2 of the foamed thermal insulation material. . That is, W5>T2, and W6>T2.

再者，突起部24的縱向寬度W5在間口側比在隔熱箱體50的背面側小。在本實施方式中，突起部24的前方側（即，間口側）僅由主體部22形成，突起部24的後方側（即，背面側）由主體部22和後方伸出部23形成。故，縱向寬度W5b比縱向寬度W5c小（即，W5b＜W5c）。Furthermore, the longitudinal width W5 of the protrusion 24 is smaller on the gap side than on the back side of the heat insulating box 50 . In this embodiment, the front side (that is, the gap side) of the protruding portion 24 is formed only by the main body portion 22 , and the rear side (that is, the back side) of the protruding portion 24 is formed by the main body portion 22 and the rear extension portion 23 . Therefore, the longitudinal width W5b is smaller than the longitudinal width W5c (that is, W5b<W5c).

在本實施方式中，後方伸出部23成為向主體部22的下方突出的形狀。由此，由於在主體部22的上表面不形成由伸出部形成的突出部，因此能夠將擱板滑動自如地載置在第二擱板支撐部21b上。再者，向第二擱板支撐部21b的下方伸出的後方伸出部23由於擱板而難以被使用者看到，因此能夠提高冷藏室11內的美觀。然，在另一實施方式中，在主體部22的後方，主體部22也可以為包含後方伸出部23的形狀。In this embodiment, the rear extension portion 23 has a shape protruding downward from the main body portion 22 . Thereby, since the protruding part formed by an extension part is not formed on the upper surface of the main body part 22, the shelf can be slidably mounted on the 2nd shelf supporting part 21b. Furthermore, since the rear extension part 23 extended downward of the 2nd shelf support part 21b is hard to be seen by a user due to the shelf, the appearance of the inside of the refrigerator compartment 11 can be improved. However, in another embodiment, the main body 22 may also have a shape including a rear extending portion 23 behind the main body 22 .

再者，在本實施方式中，突起部24的縱向寬度W5優選為突起部24的橫向寬度W6以上（即，W5≥W6）。尤其是，在位於注入口58更近的突起部24的後方側，突起部24的縱向寬度W5c優選為突起部24的橫向寬度W6以上（即，W5c≥W6）。由此，能夠促進隔熱材料向突起部24內的流入。Furthermore, in the present embodiment, the longitudinal width W5 of the protruding portion 24 is preferably equal to or larger than the transverse width W6 of the protruding portion 24 (that is, W5≥W6). In particular, on the rear side of the protrusion 24 located closer to the injection port 58 , the longitudinal width W5 c of the protrusion 24 is preferably equal to or larger than the transverse width W6 of the protrusion 24 (that is, W5c ≥ W6). This can promote the inflow of the heat insulating material into the protruding portion 24 .

再者，在本實施方式中，突起部24的縱向寬度W5優選為突起部24的橫向寬度W6與發泡隔熱材料52的厚度T2之和的值以下（即，W5≤W6+T2）。由此，能夠抑制由於突起部24的縱向寬度W5變寬而導致的箱內容積的減少。再者，更優選使W5和W6+T2為大致相等的值。Furthermore, in the present embodiment, the longitudinal width W5 of the protruding portion 24 is preferably equal to or less than the sum of the transverse width W6 of the protruding portion 24 and the thickness T2 of the foamed heat insulating material 52 (that is, W5≦W6+T2). Thereby, it is possible to suppress a decrease in the volume of the box due to an increase in the longitudinal width W5 of the protruding portion 24 . Furthermore, it is more preferable that W5 and W6+T2 have substantially equal values.

如上所述，發泡隔熱材料52的厚度T2例如設定為5mm以上15mm以下，優選地，設定為8mm以上13mm以下。在這種情況下，基於T2的設定值，以使W5和W6的值例如增大1～5mm以上的方式來決定突起部24的尺寸即可。As described above, the thickness T2 of the foamed heat insulating material 52 is set to, for example, 5 mm or more and 15 mm or less, and preferably, it is set to 8 mm or more and 13 mm or less. In this case, based on the set value of T2, the size of the protruding portion 24 may be determined such that the values of W5 and W6 are increased by, for example, 1 to 5 mm or more.

在一個示例中，W5b被設定為10mm以上15mm以下，W5c被設定為15mm以上20mm以下。再者，在一個示例中，W6被設定為10mm以上15mm以下。In one example, W5b is set to 10 mm or more and 15 mm or less, and W5c is set to 15 mm or more and 20 mm or less. Furthermore, in one example, W6 is set to 10 mm or more and 15 mm or less.

（第一實施方式的總結） 如上所述，本實施方式涉及的冰箱1具備隔熱箱體50。隔熱箱體50具有內箱70和外箱60。在隔熱箱體50內的外箱側配置有真空隔熱材料51。在隔熱箱體50的內部填充有發泡隔熱材料52。在隔熱箱體50的背面設有注入發泡隔熱材料的材料的至少一個注入口58。 (Summary of the first embodiment) As described above, the refrigerator 1 according to this embodiment includes the heat insulating box 50 . The heat insulation box 50 has an inner box 70 and an outer box 60 . A vacuum heat insulating material 51 is arranged on the outer box side in the heat insulating box 50 . The inside of the heat insulating box 50 is filled with a foamed heat insulating material 52 . At least one injection port 58 for injecting foam insulation material is provided on the back surface of the heat insulation box 50 .

在隔熱箱體50的側面部50b，與真空隔熱材料51相對的發泡隔熱材料52的厚度T2小於真空隔熱材料51的厚度T1的區域比厚度T2為真空隔熱材料51的厚度T1以上的區域多。在內箱70的側面部70b設有支撐配置於隔熱箱體50的箱內的擱板的第二擱板支撐部21b，第二擱板支撐部21b的縱向寬度W5和橫向寬度W6比發泡隔熱材料52的厚度T2大。即，W5＞T2，並且W6＞T2。In the side portion 50b of the heat insulating box 50, the thickness T2 of the foamed heat insulating material 52 facing the vacuum heat insulating material 51 is smaller than the thickness T1 of the vacuum heat insulating material 51. The thickness T2 is the thickness of the vacuum heat insulating material 51. There are many areas above T1. The side portion 70b of the inner box 70 is provided with a second shelf support portion 21b that supports a shelf arranged in the heat insulating box 50. The second shelf support portion 21b has a longitudinal width W5 and a transverse width W6. The thickness T2 of the foam insulation material 52 is large. That is, W5>T2, and W6>T2.

根據上述結構，可以得到在向隔熱箱體50注入發泡隔熱材料時，能夠更容易地在隔熱箱體內填充發泡隔熱材料的構成。更具體而言，在隔熱箱體50的側面部50b的第二擱板支撐部21b的配置部位，能夠使發泡隔熱材料的流動性提高。According to the above structure, when the foamed heat insulating material is injected into the heat insulating box 50, a structure can be obtained in which the foamed heat insulating material can be filled in the heat insulating box more easily. More specifically, the fluidity of the foamed heat insulating material can be improved at the location where the second shelf support portion 21b is arranged on the side portion 50b of the heat insulating box 50.

再者，第二擱板支撐部21b（更具體而言，後方伸出部23）優選設置在與至少一個注入口58在正面觀察時重疊的位置。由此，能夠確保從注入口58注入的隔熱材料的注入路徑，並且能夠確保因發泡而膨脹的隔熱材料的佔有區域。Furthermore, the second shelf support portion 21b (more specifically, the rear extension portion 23) is preferably provided at a position that overlaps the at least one injection port 58 when viewed from the front. Thereby, the injection path of the heat insulating material injected from the injection port 58 can be ensured, and the occupied area of the heat insulating material expanded by foaming can be ensured.

如上所述，根據本實施方式的隔熱箱體50，能夠構成為在注入發泡隔熱材料時，能夠使發泡隔熱材料更容易在隔熱箱體內流動。由此，能夠實現隔熱箱體50的側面部的薄型化，並且能夠降低在隔熱箱體50的內部產生未填充發泡隔熱材料的部位的可能性。As described above, according to the heat insulating box 50 of this embodiment, when the foamed heat insulating material is injected, the foamed heat insulating material can be configured to flow more easily within the heat insulating box. Thereby, the side surface part of the heat insulation box 50 can be made thin, and the possibility that a site|part which is not filled with the foam heat insulation material may arise in the heat insulation box 50 can be reduced.

＜第二實施方式＞ 接著，說明本發明的第二實施方式。在上述第一實施方式中，以配置於與注入口58在正面觀察時重疊的位置的第二擱板支撐部21b的突起部24具有主體部22和後方伸出部23的構成為例進行了說明。然，突起部24的構成並不限定於此。 <Second Embodiment> Next, a second embodiment of the present invention will be described. In the above-mentioned first embodiment, the configuration in which the protruding portion 24 of the second shelf support portion 21 b disposed at a position overlapping the injection port 58 in front view includes the main body portion 22 and the rear extension portion 23 is exemplified. instruction. However, the structure of the protruding portion 24 is not limited to this.

在第二實施方式涉及的隔熱箱體50中，配置於與注入口58在正面觀察時重疊的位置的突起部24具有從後方側（即，背面側）朝向前方側（即，間口側）縱向寬度W5逐漸變小的構成。與第一實施方式相同之處在於，突起部24的內徑（即，縱向寬度W5及橫向寬度W6）大於隔熱箱體50的側面部50b中的發泡隔熱材料的厚度T2。In the heat insulating box 50 according to the second embodiment, the protrusion 24 disposed at a position overlapping the injection port 58 in front view has a diameter extending from the rear side (ie, the back side) toward the front side (ie, the gap side). The longitudinal width W5 gradually becomes smaller. The same as the first embodiment is that the inner diameter of the protruding portion 24 (ie, the longitudinal width W5 and the transverse width W6) is larger than the thickness T2 of the foamed heat insulating material in the side portion 50b of the heat insulating box 50.

＜第三實施方式＞ 接著，說明本發明的第三實施方式。在上述第一實施方式中，以第二擱板支撐部21b的突起部24配置於與注入口58在正面觀察時重疊的位置的構成為例進行了說明。然，突起部24也可以無需一定配置於與注入口在正面觀察時重疊的位置。 <Third Embodiment> Next, a third embodiment of the present invention will be described. In the above-mentioned first embodiment, an example has been described in which the protruding portion 24 of the second shelf support portion 21b is disposed at a position overlapping the injection port 58 when viewed from the front.
