Description

隔熱箱體、冰箱以及隔熱箱體的製造方法Thermal insulation box, refrigerator, and method of manufacturing thermal insulation box

本發明的一個方面涉及一種設置在冰箱等中的隔熱箱體以及具備該隔熱箱體的冰箱。另外,本發明的一個方面涉及一種隔熱箱體的製造方法。One aspect of the present invention relates to a heat insulation box provided in a refrigerator or the like, and a refrigerator provided with the heat insulation box. In addition, one aspect of the present invention relates to a method of manufacturing a 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 heat insulation from the surroundings, the refrigerator is provided with a heat insulation box so as to cover the outer periphery of the storage space. The thermal insulation box is composed of an outer box, an inner box, and a thermal insulation material filled therebetween. As a heat insulating material, foam heat insulating materials, such as a rigid foam urethane heat insulating material, are used, for example.

近年來,為了進一步提高隔熱性能,提出了在隔熱箱體內配置真空隔熱材料的方案。通過使用真空隔熱材料,隔熱性能提高,使隔熱箱體的厚度變薄。In recent years, in order to further improve the thermal insulation performance, it has been proposed to arrange a vacuum thermal insulation material in a thermal insulation box. By using the vacuum heat insulating material, the heat insulating performance is improved, and the thickness of the heat insulating box is reduced.

然而,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,發泡隔熱材料變得難以流動,因此,在隔熱材料發泡後有可能產生未填充有發泡隔熱材料的空洞(空隙)。However, as the thickness of the heat insulating box becomes thinner, the space for the foamed heat insulating material in the heat insulating box to flow is narrowed, and it becomes difficult for the foamed heat insulating material to flow. Therefore, after the heat insulating material is foamed, there may be a Cavities (voids) that are not filled with foam insulating material.

因此,在日本特開2019-45144號公報中公開了如下結構:在形成於內箱與外箱之間的隔熱空間的側面部分設置有側面真空隔熱板及發泡隔熱材料的冰箱中,在側面真空隔熱板的後方,即與設置於外箱的背面的發泡隔熱材料的發泡原液的注入孔在上下方向上重疊的位置設置填充物。Therefore, Japanese Patent Application Laid-Open No. 2019-45144 discloses a structure in a refrigerator in which a side vacuum insulation panel and a foam insulation material are provided in a side part of a thermal insulation space formed between an inner box and an outer box. A filler is installed at the rear of the side vacuum insulation panel, that is, at a position overlapping in the vertical direction with the injection hole of the foaming stock solution of the foaming insulation material provided on the back of the outer box.

但是,若隔熱箱體的進一步向薄壁化進展,則依然存在產生未填充發泡隔熱材料的空隙的可能性。However, when further thinning of the heat insulating box progresses, there is still a possibility that voids in which the foamed heat insulating material is not filled are generated.

因此,在本發明的一個實施方式中,目的在於提供在向隔熱箱體注入發泡隔熱材料時,能夠使發泡隔熱材料在隔熱箱體內更容易填充的構成及製造方法。Therefore, in one Embodiment of this invention, when injecting a foam heat insulation material into a heat insulation box, it aims at providing the structure and manufacturing method which can make it easier to fill a foam heat insulation material in a heat insulation box.

The heat insulating box includes a vacuum heat insulating material disposed on the outer box side of the heat insulating box body, and a foam heat insulating material filled in the heat insulating box body. At least one injection port for injecting the material of the foamed heat insulating material is provided on the back of the heat insulating box. The inner box has a back surface portion and a side surface portion, and the side surface portion is provided with at least one protruding portion partially raised inward of the box. And the said extension part is arrange|positioned at the position which overlaps with the said injection port, when it sees from the back.

另外,本發明的又一個方面涉及一種隔熱箱體的製造方法。該隔熱箱體的製造方法,包括在設置於具有外箱和內箱的隔熱箱體的背面部的注入口安裝排出發泡隔熱材料的材料的注入噴嘴,從所述注入噴嘴向所述隔熱箱體的內部注入所述材料的工序。在該製造方法中,若將所述隔熱箱體的側面部的內部的厚度設為T1,將在所述隔熱箱體的所述側面部的內部的所述外箱側設置的真空隔熱材料(例如真空隔熱材料51)的厚度設為T2,將向設置於所述隔熱箱體的背面部的注入口插入的所述注入噴嘴的內徑設為Φ1,則 (T2+Φ1)>T1 所述注入噴嘴安裝於從背面觀察時與在所述內箱的側面部以向箱內側部分隆起的方式設置的伸出部重疊的位置。 Moreover, another aspect of this invention relates to the manufacturing method of a heat insulating box. The method for manufacturing a heat insulating box includes attaching an injection nozzle for discharging a material of a foamed heat insulating material to an injection port provided on a rear surface of a heat insulating box having an outer case and an inner case, and injecting the material from the injection nozzle to the The process of injecting the material into the inside of the heat insulating box. In this manufacturing method, if the thickness of the inside of the side portion of the heat insulating box is T1, the vacuum barrier provided inside the side portion of the heat insulating box on the side of the outer box Let the thickness of the heat material (for example, the vacuum heat insulating material 51) be T2, and let the inner diameter of the injection nozzle inserted into the injection port provided on the back surface of the heat insulation box be Φ1, then (T2+Φ1)>T1 The said injection nozzle is attached in the position which overlaps with the protrusion part provided so that the side part of the said inner case may bulge toward the tank inner side part, when it sees from the back.

Partitions 59 are provided between the storage spaces. However, 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。另外,在將冰箱1載置於設置面的狀態下,將冰箱1的上下的方向的方向稱為冰箱1(或隔熱箱體50等)的上下方向。另外,在將冰箱1載置於設置面的狀態下,從正面觀察冰箱1時的前後的方向稱為冰箱1(或隔熱箱體50等)的前後方向。In this embodiment, the surface in which the door is provided is called the front surface or the front surface of the refrigerator. And each surface of the refrigerator 1 is made into an upper surface, a side surface, a back surface, and a bottom surface based on the position which exists when the refrigerator 1 is installed in a normal state based on the front surface as a reference. In addition, when the refrigerator 1 is placed on the installation surface, the direction of the up-down direction of the refrigerator 1 is called the up-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-rear direction when the refrigerator 1 is viewed from the front is referred to as the front-rear direction of the refrigerator 1 (or the heat insulation box 50 or the like).

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

另外,在冰箱1的內部設有控制部(未圖示)。該控制部對製冷迴圈的運轉進行控制。即,控制部通過驅動壓縮機31,開始製冷迴圈的運轉,製冷劑在迴圈內流通。如圖1所示,壓縮機31配置在設於冰箱1的底部的背面側的設備室30內。In addition, a control unit (not shown) is provided inside the refrigerator 1 . The control unit controls the operation of the refrigeration loop. That is, the control unit starts the operation of the refrigeration loop by driving the compressor 31, and the refrigerant circulates in the loop. As shown in FIG. 1, the compressor 31 is arrange|positioned in the equipment room 30 provided in the back side of the bottom part of the refrigerator 1. As shown in FIG.

冷卻器32配置在設於冰箱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與各儲藏空間之間迴圈而設置的。The cooler 32 is arranged in the cooling chamber 35 provided on the rear side of the refrigerator 1 . In the cooling chamber 35 , in addition to the cooler 32 , a cooling fan 33 and the like are provided. The cooling fan 33 is provided to circulate air between the cooling chamber 35 and each storage space.

(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,設置有隔熱箱體50。隔熱箱體50以覆蓋冰箱1的外周的方式設置。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56。圖2表示從正面側觀察隔熱箱體50的外觀。 (Constitution of heat insulation box) In the refrigerator 1, the heat insulating box 50 is provided as a heat insulating structure for insulating each storage space from the surroundings. The heat insulating box 50 is provided so as to cover the outer periphery of the refrigerator 1 . As shown in FIG. 1 , the heat insulating box 50 mainly includes an outer case 60 , an inner case 70 , a vacuum heat insulating material 51 , and a foamed heat insulating material 56 . FIG. 2 shows the external appearance of the heat insulating box 50 viewed from the front side.

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。此外,內箱70形成儲藏空間(例如,第一冷藏室11、第二冷藏室12、冷凍室13)的內壁和冷卻室35的後壁。The outer case 60 forms the outer peripheral surface of the heat insulating case 50 . The outer case 60 is mainly composed of an upper surface portion 60a, a side surface portion 60b, a rear surface portion 60c, and a bottom surface portion. The inner box 70 forms the inner peripheral surface of the heat insulating box 50 . Further, the inner box 70 forms the inner wall of the storage space (eg, the first refrigerating chamber 11 , the second refrigerating chamber 12 , the freezing chamber 13 ) and the rear wall of the cooling chamber 35 .

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

這樣,設備室30與冷凍室13被隔熱箱體50隔離。因此,能夠抑制在設備室30內產生的熱流入到冷凍室13。In this way, the equipment compartment 30 and the freezer compartment 13 are isolated by the heat insulating box 50 . Therefore, the heat generated in the equipment room 30 can be suppressed from flowing into the freezer compartment 13 .

真空隔熱材料51和發泡隔熱材料56設置在外箱60與內箱70之間的空間內。真空隔熱材料51也稱為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。如圖1等所示,真空隔熱材料51配置在隔熱箱體50內的外箱60側。The vacuum heat insulating material 51 and the foamed heat insulating material 56 are provided in the space between the outer case 60 and the inner case 70 . The vacuum heat insulating material 51 is also called VIP, and is a sheet-like or plate-like heat insulating material.

As shown in FIG. 1 etc., the vacuum heat insulating material 51 is arrange|positioned in the heat insulating box 50 on the outer box 60 side.

發泡隔熱材料56例如可以由發泡聚氨酯(也稱為硬質聚氨酯泡沫)等形成。如圖1所示,在分隔各貯藏空間的分隔部59的內部也填充有發泡隔熱材料56。此外,在分隔部59的內部,也可以設置與在外箱60和內箱70之間的空間內設置的發泡隔熱材料56不同的隔熱材料。The foamed heat insulating material 56 may be formed of, for example, foamed urethane (also referred to as rigid urethane foam) or the like. As shown in FIG. 1, the inside of the partition part 59 which partitions each storage space is also filled with the foam heat insulating material 56. As shown in FIG. Moreover, in the inside of the partition part 59, you may provide the heat insulating material different from the foam heat insulating material 56 provided in the space between the outer case 60 and the inner case 70.

發泡隔熱材料56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,從而填充在隔熱箱體50內。外箱60的背面部60c上設置有注入隔熱材料的注入口58(參照圖3)。在本實施方式中,在背面部60c的左側的端部附近設置有兩個注入口58,在背面部60c的右側的端部附近設置有兩個注入口58,共計設置有四個注入口58。但是,注入口58的個數不限於此。The foamed heat insulating material 56 injects a liquid foamed polyurethane material (also referred to as a foamed heat insulating material, a heat insulating material) into the heat insulating box 50 to foam the material in the heat insulating box 50, Thereby, the inside of the heat insulating box 50 is filled. The back surface part 60c of the outer case 60 is provided with the injection port 58 (refer FIG. 3) which injects a heat insulating material. In the present embodiment, two injection ports 58 are provided in the vicinity of the left end portion of the back surface portion 60c, and two injection ports 58 are provided in the vicinity of the right end portion of the back surface portion 60c, for a total of four injection ports 58 . However, the number of the injection ports 58 is not limited to this.

如圖2所示,由內箱70形成的箱內的內壁主要由上面壁70a、側面壁(側面部)70b、背面壁(背面部)70c以及底面壁70d構成。側面壁70b具有部分地向箱內側隆起的部位。As shown in FIG. 2 , the inner wall in the box formed by the inner box 70 is mainly composed of an upper surface wall 70a, a side wall (side surface portion) 70b, a rear surface wall (rear surface portion) 70c, and a bottom surface wall 70d. The side wall 70b has a part raised to the inside of a case partially.

例如,在形成冷藏室11的箱內的上方部分的側面壁70b,作為這樣的隆起的部分,設置有多個擱板支承部。擱板支承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的上方側依次設置有第一擱板支承部21a、第二擱板支承部21b和第三擱板支承部21c這三個擱板保持部。各擱板支承部左右對稱地配置於左側的側面壁70b和右側的側面壁70b。For example, the side wall 70b which forms the upper part in the inside of the refrigerator compartment 11 is provided with several shelf support parts as such a raised part. The shelf support part holds a shelf (not shown) for dividing the inside of the refrigerator compartment 11 . In this embodiment, three shelf holding parts of the first shelf support part 21a, the second shelf support part 21b, and the third shelf support part 21c are provided in this order from the upper side of the refrigerator compartment 11. Each shelf support part is symmetrically arrange|positioned at the side wall 70b of the left side, and the side wall 70b of the right side.

另外,在形成冷凍室13的箱內的下方部分的側面壁70b,作為這樣的隆起的部分,設置有收納容器保持部23。收納容器保持部23保持配置在冷凍室13內的收納容器(未圖示)。收納容器保持部23分別左右對稱地配置於左側的側面壁70b和右側的側面壁70b。Moreover, the side wall 70b which forms the lower part in the box inside the freezer compartment 13 is provided with the container holding|maintenance part 23 as such a raised part. The storage container holding part 23 holds the storage container (not shown) arranged in the freezer compartment 13 . The container holding portion 23 is arranged symmetrically on the left side wall 70b and the right side wall 70b, respectively.

首先,在外箱60的各面部(具體而言,上面部60a、側面部60b和背面部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。另外,在內箱70的規定位置安裝箱內電裝單元、各種佈線等部件。First, components such as vacuum heat insulating material 51 and heat pipes (not shown) are attached to predetermined positions on the inner surface of each surface portion (specifically, upper surface portion 60a, side surface portion 60b, back surface portion 60c, etc.) of outer case 60 . In addition, components such as electric components in the box, various wirings, etc., are attached to 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 portion of the outer case 60 is attached so as to cover the outer periphery of the inner case 70 . Thereby, the outer shape of the heat insulating box 50 is formed.

之後,在使隔熱箱體50的背面部60c上升的狀態下,從形成於背面部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,在注入口58中插入隔熱材料的注入裝置的注入噴嘴91(參照圖3)。從注入噴嘴91向隔熱箱體50內排出的發泡隔熱材料的材料在外箱60和內箱70之間的空間內從前表面側(開口部50a側)向背面側依次發泡,一邊增加體積一邊填充。發泡的隔熱材料之後固化。Then, in the state which raised the back surface part 60c of the heat insulation box 50, the material (foamed urethane material) of a liquid foam heat insulating material is injected from the injection port 58 formed in the back surface part 60c. At this time, the injection nozzle 91 (refer to FIG. 3 ) of the injection device of the heat insulating material is inserted into the injection port 58 . The material of the foamed heat insulating material discharged from the injection nozzle 91 into the heat insulating box 50 is gradually foamed in the space between the outer case 60 and the inner case 70 from the front surface side (the opening portion 50a side) to the back surface side, and increases while increasing. Fill in volume. The foamed insulating material is then cured.

即,當在使隔熱箱體50的背面部60c在上的狀態下從各注入口58注入隔熱材料時,隔熱材料由於重力,通過隔熱箱體50內的側面部和上面部等,朝向位於最下方的開口部50a流下。That is, when the heat insulating material is injected from each injection port 58 with the back surface 60c of the heat insulating box 50 up, the heat insulating material passes through the side surface and the upper surface of the heat insulating box 50 due to gravity. , and flows down toward the opening 50a located at the bottom.

在近年來的冰箱中,以確保更大的箱內空間等為目的,期望著隔熱箱體50的側壁的薄型化。隔熱箱體50的側壁的厚度變薄,從而在側壁內隔熱材料流動的空間變窄,隔熱材料變得難以流動。如果在隔熱箱體50的內部設置真空隔熱材料51,則隔熱材料的流動空間變得更窄。由此,在隔熱箱體50內,注入的隔熱材料發泡後,產生未填充發泡隔熱材料的空洞(空隙)的可能性提高。即,當注入液體狀的發泡隔熱材料時,如果與隔熱箱體50內的壁面碰撞,則有時會在該部位部分地開始發泡,之後,隔熱材料一邊從隔熱箱體50的前表面側發泡一邊被填充時,有可能該部分發泡的部位成為障礙物,填充變得不均勻。In recent refrigerators, for the purpose of securing a larger interior space, etc., the thickness reduction of the side wall of the heat insulating box 50 is desired. When the thickness of the side wall of the heat insulating box 50 becomes thin, the space in which the heat insulating material flows in the side wall becomes narrow, and it becomes difficult for the heat insulating material to flow. When the vacuum heat insulating material 51 is provided inside the heat insulating box 50, the flow space of the heat insulating material becomes narrower. Thereby, in the heat insulating box 50, after the injected heat insulating material is foamed, the possibility of generating a cavity (void) in which the foamed heat insulating material is not filled increases. That is, when a liquid foamed heat insulating material is injected, if it collides with the wall surface in the heat insulating box 50, foaming may be partially started at that portion, and then the heat insulating material is removed from the heat insulating box while the heat insulating material is injected. When the front surface side of 50 is filled while being foamed, there is a possibility that the partially foamed portion becomes an obstacle and the filling becomes uneven.

因此,在本實施方式中,通過將插入有注入噴嘴91的注入口58的配置位置限定為規定的部位,能夠抑制在注入液體狀的發泡隔熱材料時碰撞隔熱箱體50內的壁面,能夠使液體狀的發泡隔熱材料均勻地遍佈隔熱箱體50的前表面側。因此,在薄壁化中,也能夠更加良好地使發泡隔熱材料向箱體中的填充,抑制注入的隔熱材料的流動降低。關於這一點以下進行說明。Therefore, in the present embodiment, by limiting the arrangement position of the injection port 58 into which the injection nozzle 91 is inserted to a predetermined location, it is possible to suppress the collision with the wall surface in the heat insulation box 50 when injecting the liquid foam heat insulating material. , the liquid foam heat insulating material can be uniformly distributed on the front surface side of the heat insulating box 50 . Therefore, even in the thinning, it is possible to more favorably fill the foam heat insulating material into the box, and to suppress a decrease in the flow of the injected heat insulating material. This point will be described below.

(關於注入口(或注入噴嘴)的配置位置) 圖4示出隔熱箱體50的箱內側的側面部的結構。隔熱箱體50的箱內側的側面部由內箱70的側面壁70b構成。如上所述,在內箱70的側面壁70b例如存在架板支承部21a〜21c和收納容器保持部23等那樣向箱內側部分地隆起的部位。 (About the location of the injection port (or injection nozzle)) FIG. 4 shows the structure of the side surface part inside the box of the heat insulating box 50 . The side surface part of the box inner side of the heat insulation box 50 is comprised by the side wall 70b of the inner box 70. As described above, on the side wall 70b of the inner box 70, for example, the shelf plate support portions 21a to 21c, the container holding portion 23, etc., have portions that partially bulge inward of the box.

圖4所示的虛線框是將在注入隔熱材料時注入噴嘴91所插入的部位向隔熱箱體50的前表面側(開口部50a側)延長而成的。The dotted-line frame shown in FIG. 4 is formed by extending the site where the injection nozzle 91 is inserted when injecting the heat insulating material to the front surface side (opening portion 50a side) of the heat insulation box 50 .

插入隔熱箱體50的上方側的注入口58的注入噴嘴91的延長部分與形成於內箱70的側面壁70b的第二擱板支承部21b的一部分對應。將與該注入噴嘴91的延長部分對應的第二擱板支承部21b的一部分稱為伸出部73。An extension of the injection nozzle 91 inserted into the injection port 58 on the upper side of the heat insulating box 50 corresponds to a part of the second shelf support portion 21 b formed on the side wall 70 b of the inner box 70 . The part of the 2nd shelf support part 21b corresponding to the extension part of this injection nozzle 91 is called the extension part 73. As shown in FIG.

另外,插入隔熱箱體50的下方側的注入口58的注入噴嘴91的延長部分與形成於內箱70的側面壁70b的收納容器保持部23的一部分對應。將與該注入噴嘴91的延長部分對應的收納容器保持部23的一部分稱為伸出部83。Moreover, the extension part of the injection nozzle 91 inserted in the injection port 58 of the lower side of the heat insulation box 50 corresponds to a part of the container holding part 23 formed in the side wall 70b of the inner box 70. A part of the container holding part 23 corresponding to the extension of the injection nozzle 91 is referred to as an extension part 83 .

伸出部73及83設置於從背面觀察(或正面觀察)時設置在與設置於背面部60c的注入口58重疊的位置。由此,確保從插入到注入口58的注入噴嘴91注入的隔熱材料的注入路徑71和81。The extension parts 73 and 83 are provided in the position which overlaps with the injection port 58 provided in the back surface part 60c, when it sees from the back surface (or front view). Thereby, the injection paths 71 and 81 of the heat insulating material injected from the injection nozzle 91 inserted into the injection port 58 are ensured.

圖5表示內箱70的左側的側面壁70b的橫剖面的結構。圖5為圖4中的A-A線部分的剖視圖。在圖5中,能夠確認由第二擱板支承部21b的一部分形成的伸出部73的形狀。FIG. 5 shows the structure of the transverse cross-section of the left side wall 70b of the inner box 70. As shown in FIG. FIG. 5 is a cross-sectional view of the portion taken along the line A-A in FIG. 4 . In FIG. 5, the shape of the extension part 73 formed by a part of the 2nd shelf support part 21b can be confirmed.

此外,在內箱70中,在側面壁70b與背面壁70c的邊界部設置有傾斜面部72。通過設置這樣的傾斜面部72,側面壁70b與背面壁70c的連接部分成為倒角的形狀。而且,設置於側面壁70b的伸出部73與傾斜面部72連續設置。由此,在隔熱箱體50的內部,能夠從背面側朝向側面部確保從傾斜面部72向伸出部73連續的隔熱材料的注入路徑71。同樣地,在隔熱箱體50的內部,能夠從背面側朝向側面部確保從傾斜面部72向伸出部83連續的隔熱材料的注入路徑81。Moreover, in the inner box 70, the inclined surface part 72 is provided in the boundary part of the side wall 70b and the back wall 70c. By providing such an inclined surface part 72, the connection part of the side wall 70b and the back wall 70c becomes a chamfered shape. Moreover, the extension part 73 provided in the side wall 70b is provided continuously with the inclined surface part 72. As shown in FIG. Thereby, in the inside of the heat insulation box 50, the injection path 71 of the heat insulating material continuous from the inclined surface part 72 to the extension part 73 can be ensured from the back surface side toward the side surface part. Similarly, in the inside of the heat insulation box 50, the injection path 81 of the heat insulating material continuous from the inclined surface part 72 to the extension part 83 can be ensured from the back surface side toward the side surface part.

圖6表示內箱70的縱剖面的結構。圖6為圖4中的B-B線部分的剖視圖。圖6還示出了隔熱材料的注入噴嘴91的內徑的位置。在圖7中,將圖6所示的隔熱箱體50的內箱70的第二擱板支承部21b的周邊(C所示的虛線框部分)放大表示。在圖8中,將圖6所示的隔熱箱體50的內箱70的收納容器保持部23的周邊(D所示的虛線框部分)放大表示。FIG. 6 shows the structure of the longitudinal section of the inner case 70 . FIG. 6 is a cross-sectional view of the portion taken along the line B-B in FIG. 4 . FIG. 6 also shows the location of the inner diameter of the injection nozzle 91 of the insulating material. In FIG. 7, the periphery of the 2nd shelf support part 21b of the inner box 70 of the heat insulation box 50 shown in FIG. 6 (broken line frame part shown by C) is enlarged and shown. In FIG. 8 , the periphery of the container holding portion 23 of the inner box 70 of the heat insulation box 50 shown in FIG. 6 is enlarged and shown (the portion shown by the broken line frame in D).

如圖7所示,作為第二擱板支承部21b的一部分的伸出部73從背面觀察(或正面觀察)時與插入注入口58的注入噴嘴91的配置位置重疊。另外,由於供注入噴嘴91插入的注入口58的配置位置包括注入噴嘴91的配置位置,因此注入口58的配置位置也與伸出部73重疊。As shown in FIG. 7 , the projecting portion 73 that is a part of the second shelf support portion 21b overlaps with the arrangement position of the injection nozzle 91 inserted into the injection port 58 when viewed from the back (or when viewed from the front). In addition, since the arrangement position of the injection port 58 into which the injection nozzle 91 is inserted includes the arrangement position of the injection nozzle 91 , the arrangement position of the injection port 58 also overlaps with the extension portion 73 .

而且,優選注入噴嘴91的配置區域(在圖7中標注了斜線的區域)包含於包括伸出部73的內箱70的側面壁70b內的區域。由此,能夠降低在隔熱箱體50的背面側(即,靠近注入噴嘴91的一側)的隔熱材料的注入路徑71存在成為隔熱材料的流動障礙的部位的可能性。Furthermore, it is preferable that the disposition area of the injection nozzle 91 (the area marked with hatching in FIG. 7 ) is included in the area in the side wall 70 b of the inner case 70 including the protruding portion 73 . Thereby, the possibility that the injection path 71 of the heat insulating material on the back side of the heat insulating box 50 (that is, the side close to the injection nozzle 91 ) exists as an obstacle to the flow of the heat insulating material can be reduced.

此外,第二擱板支承部21b可以包含伸出部73,但也可以形成為伸出部73從第二擱板支承部21b突出的形狀。在該情況下,如圖7所示,伸出部73優選設為向第二擱板支承部21b的下方突出的形狀。由此,在第二擱板支承部21b的上表面未形成有伸出部73的突出部,因此能夠將擱板滑動自如地載置在第二擱板支承部21b上。另外,由於利用擱板使用者難以看到向第二擱板支承部21b的下方伸出的伸出部73,所以能夠提高冷藏室11內的美觀性。In addition, although the 2nd shelf support part 21b may contain the extension part 73, it may be formed in the shape which the extension part 73 protrudes from the 2nd shelf support part 21b. In this case, as shown in FIG. 7, it is preferable that the extension part 73 is made into the shape which protrudes below the 2nd shelf support part 21b. Thereby, since the protrusion part of the extension part 73 is not formed in the upper surface of the 2nd shelf support part 21b, a shelf can be slidably mounted on the 2nd shelf support part 21b. Moreover, since it is difficult for a user to see the extension part 73 which protrudes below the 2nd shelf support part 21b by a shelf, the appearance in the refrigerator compartment 11 can be improved.

如圖8所示,作為收納容器保持部23的一部分的伸出部83從背面觀察(或正面觀察)時與插入注入口58的注入噴嘴91的配置位置重疊。另外,由於供注入噴嘴91插入的注入口58的配置位置包括注入噴嘴91的配置位置,因此注入口58的配置位置也與伸出部83重疊。As shown in FIG. 8 , the projecting portion 83 that is a part of the container holding portion 23 overlaps with the arrangement position of the injection nozzle 91 inserted into the injection port 58 when viewed from the back (or when viewed from the front). In addition, since the arrangement position of the injection port 58 into which the injection nozzle 91 is inserted includes the arrangement position of the injection nozzle 91 , the arrangement position of the injection port 58 also overlaps with the extension portion 83 .

而且,優選注入噴嘴91的配置區域(在圖8中標注了斜線的區域)包含於包括伸出部83的內箱70的側面壁70b內的區域。由此,能夠降低在隔熱箱體50的背面側(即,靠近注入噴嘴91的一側)的隔熱材料的注入路徑81存在成為隔熱材料的流動障礙的部位的可能性。Furthermore, it is preferable that the disposition area of the injection nozzle 91 (the area marked with hatching in FIG. 8 ) is included in the area in the side wall 70 b of the inner case 70 including the protruding portion 83 . Thereby, the possibility that the injection path 81 of the heat insulating material on the back side of the heat insulating box 50 (that is, the side close to the injection nozzle 91 ) exists as an obstacle to the flow of the heat insulating material can be reduced.

此外,收納容器保持部23可以包含伸出部83,但也可以形成為伸出部83從收納容器保持部23突出的形狀。在該情況下,伸出部83優選設為向收納容器保持部23的下方突出的形狀。由此,在收納容器保持部23的上表面未形成有伸出部83的突出部,因此能夠將收納容器滑動自如地載置在收納容器保持部23上。另外,由於利用收納容器使用者難以看到向收納容器保持部23的下方伸出的伸出部83,所以能夠提高冷凍室13內的美觀性。In addition, the container holding part 23 may include the extension part 83 , but may be formed in a shape in which the extension part 83 protrudes from the container holding part 23 . In this case, it is preferable that the extension part 83 has a shape which protrudes below the container holding part 23 . Thereby, since the protruding part of the extension part 83 is not formed in the upper surface of the container holding part 23, a container can be mounted on the container holding part 23 slidably. In addition, since it is difficult for the user to see the protruding portion 83 extending below the container holding portion 23 using the container, the appearance in the freezer compartment 13 can be improved.

(關於伸出部的尺寸) 接著,參照圖9對隔熱箱體50的側面部的厚度、伸出部73和83的尺寸以及注入噴嘴91的直徑的關係進行說明。 (About the dimensions of the overhang) Next, the relationship between the thickness of the side surface portion of the heat insulating box 50 , the dimensions of the protruding portions 73 and 83 , and the diameter of the injection nozzle 91 will be described with reference to FIG. 9 .

如上所述,隔熱箱體50的製造方法包括在設置於隔熱箱體50的背面部60c的注入口58安裝排出隔熱材料的注入噴嘴91,從注入噴嘴91向隔熱箱體50的內部注入隔熱材料的工序。As described above, the method of manufacturing the heat insulation box 50 includes attaching the injection nozzle 91 for discharging the heat insulating material to the injection port 58 provided in the back surface portion 60 c of the heat insulation box 50 , and injecting the heat insulation box 50 from the injection nozzle 91 to the injection nozzle 91 . The process of injecting heat insulating material inside.

在此,將插入到注入口58的注入噴嘴的內徑設為Φ1。Φ1設定為例如12mm以上且30mm以下(具體而言為18mm)。注入口58的開口直徑Φ2設計成比注入噴嘴91的內徑(Φ1)稍大。例如,注入口58的開口直徑Φ2設計得比注入噴嘴的內徑Φ1大5~20mm左右。Here, let the inner diameter of the injection nozzle inserted into the injection port 58 be Φ1. Φ1 is set to, for example, 12 mm or more and 30 mm or less (specifically, 18 mm). The opening diameter Φ2 of the injection port 58 is designed to be slightly larger than the inner diameter (Φ1 ) of the injection nozzle 91 . For example, the opening diameter Φ2 of the injection port 58 is designed to be approximately 5 to 20 mm larger than the inner diameter Φ1 of the injection nozzle.

另外,將隔熱箱體50的側面部的內部的厚度設為T1。此外,此處所說的側面部的內部的厚度是指未設置伸出部73(或伸出部83)等的部分的側面部的後端部的厚度(例如內箱70的背面壁70c的位置、或傾斜面部72的前端的側面部的厚度)。T1例如設定為25mm以上且35mm以下。In addition, let the thickness of the inside of the side surface part of the heat insulation box 50 be T1. In addition, the thickness of the inside of the side portion referred to here refers to the thickness of the rear end portion of the side portion of the portion where the overhang portion 73 (or the overhang portion 83 ) and the like are not provided (for example, the position of the rear wall 70c of the inner box 70 ). , or the thickness of the side surface of the front end of the inclined surface portion 72). T1 is set to, for example, 25 mm or more and 35 mm or less.

另外,將安裝在隔熱箱體50的內部的外箱側的真空隔熱材料51的厚度設為T2。T2例如設定為10mm以上且且20mm以下(具體為15mm)。In addition, let the thickness of the vacuum heat insulating material 51 attached to the outer case side inside the heat insulating box 50 be T2. T2 is set to, for example, 10 mm or more and 20 mm or less (specifically, 15 mm).

在本實施方式中,為了實現隔熱箱體50的側面部的薄型化,設計為相對於注入噴嘴91的內徑Φ1,隔熱箱體50的側面部的內部空間(從隔熱箱體50的側面部除去真空隔熱材料51的配置區域的部分)的厚度(即T1-T2)變小。In the present embodiment, in order to reduce the thickness of the side surface of the heat insulation box 50, with respect to the inner diameter Φ1 of the injection nozzle 91, the inner space of the side surface of the heat insulation box 50 (from the heat insulation box 50 The thickness (ie, T1 - T2 ) of the side surface (excluding the portion where the vacuum heat insulating material 51 is arranged) is reduced.

即,在如上述那樣設計隔熱箱體50和注入噴嘴91的各尺寸的情況下,以下的關係式成立。 (T2+Φ1)>T1 That is, when the dimensions of the heat insulation box 50 and the injection nozzle 91 are designed as described above, the following relational expressions are established. (T2+Φ1)>T1

向具有這樣的尺寸的隔熱箱體50注入隔熱材料時,如圖9所示,優選真空隔熱材料51的配置位置與注入噴嘴91的安裝位置從背面觀察(或正面觀察)時不重疊。由此,能夠避免從注入噴嘴91排出的隔熱材料直接接觸真空隔熱材料51的端部。When injecting the heat insulating material into the heat insulating box 50 having such a size, as shown in FIG. 9 , it is preferable that the arrangement position of the vacuum heat insulating material 51 and the installation position of the injection nozzle 91 do not overlap when viewed from the back (or when viewed from the front). . Thereby, the heat insulating material discharged from the injection nozzle 91 can be prevented from directly contacting the end of the vacuum heat insulating material 51 .

進而,注入噴嘴91安裝於從背面觀察時與設置於內箱70的側面壁70b的伸出部73(或伸出部83)重疊的位置(參照圖7和圖8)。由此,在厚度薄的隔熱箱體50的側面部,能夠確保比較大的空間作為隔熱材料的注入路徑71(或注入路徑81)。因此,向隔熱箱體50注入隔熱材料時,能夠使隔熱材料更容易在隔熱箱體內流動。Furthermore, the injection nozzle 91 is attached to the position which overlaps the extension part 73 (or the extension part 83) provided in the side wall 70b of the inner case 70 when it sees from the back side (refer FIG. 7 and FIG. 8). Thereby, a relatively large space can be secured as the injection path 71 (or injection path 81 ) of the heat insulating material in the side surface portion of the heat insulating box 50 having a thin thickness. Therefore, when the heat insulating material is injected into the heat insulating box 50, the heat insulating material can be made to flow more easily in the heat insulating box.

另外,將伸出部73(或伸出部83)的伸出尺寸設為W時, 則優選為(T1+W)>(T2+Φ1)。 In addition, when the projecting dimension of the projecting portion 73 (or the projecting portion 83 ) is W, Then, it is preferably (T1+W)>(T2+Φ1).

伸出尺寸W的大小可根據注入噴嘴91的直徑Φ1及隔熱箱體50的側面部的厚度T1等適當設定。W例如設定為1mm以上且20mm以下。The size of the protruding dimension W can be appropriately set according to the diameter Φ1 of the injection nozzle 91 , the thickness T1 of the side surface portion of the heat insulating box 50 , and the like. W is set to, for example, 1 mm or more and 20 mm or less.

通過如上述那樣設定伸出尺寸W,能夠確保較大的空間作為隔熱材料的注入路徑71(或注入路徑81)。By setting the projection dimension W as described above, a large space can be secured as the injection path 71 (or injection path 81 ) of the heat insulating material.

另外,如圖5及圖9所示,伸出部73(或伸出部83)也可以不延伸到隔熱箱體50的前端,例如,也可以延伸到比第二擱板支承部21b、收納容器保持部23的前端靠後部的位置。此時,如圖9所示,伸出部73(或伸出部83)的前端優選為朝向隔熱箱體50的內部傾斜的傾斜面。由此,能夠使伸出部73(或伸出部83)不被用戶注意到,能夠提高美觀性。另外,通過形成朝向隔熱箱體50的內部傾斜的傾斜面,能夠抑制流到伸出部73(或伸出部83)的隔熱材料滯留於伸出部73(或伸出部83)的前端。In addition, as shown in FIGS. 5 and 9 , the extension portion 73 (or the extension portion 83 ) does not need to extend to the front end of the heat insulation box 50 , but may, for example, extend beyond the second shelf support portion 21 b , The front end of the container holding portion 23 is positioned at the rear. At this time, as shown in FIG. 9 , the front end of the extension portion 73 (or the extension portion 83 ) is preferably an inclined surface inclined toward the inside of the heat insulation box 50 . Thereby, the protruding portion 73 (or the protruding portion 83 ) can be prevented from being noticed by the user, and the appearance can be improved. In addition, by forming the inclined surface inclined toward the inside of the heat insulating box 50 , it is possible to suppress the heat insulating material flowing to the extension portion 73 (or the extension portion 83 ) from remaining in the extension portion 73 (or the extension portion 83 ). front end.

(第一實施方式的總結) 如上所述,本實施方式涉及的冰箱1具有隔熱箱體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的背面設有注入發泡隔熱材料的材料的至少一個注入口58。內箱70具有背面壁70c和側面壁70b,在側面壁70b上設置有向箱內側部分地隆起的至少一個伸出部73和83。伸出部73及83設置於從背面觀察時與注入口58重疊的位置。 (Summary of the first embodiment) As described above, the refrigerator 1 according to the present embodiment includes the heat insulating box 50 . The heat insulating box 50 has an inner box 70 and an outer box 60 . A vacuum heat insulating material 51 is arranged on the outer case side in the heat insulating case 50 . At least one injection port 58 into which the material of the foamed heat insulating material is injected is provided on the back surface of the heat insulating box 50 . The inner box 70 has a back wall 70c and a side wall 70b on which at least one protrusions 73 and 83 partially bulged inward of the box are provided. The protruding portions 73 and 83 are provided at positions overlapping the injection port 58 when viewed from the back.

根據上述的結構,能夠設為安裝於注入口58的注入噴嘴91的配置區域(在圖7或圖8中標注斜線的區域)包含於包括伸出部73或83的內箱70的側面壁70b內的區域的結構。由此,能夠在隔熱箱體50的背面側(即,靠近注入噴嘴91的一側)的隔熱材料的注入路徑71或81處減少存在成為隔熱材料的流動障礙的部位。According to the above-mentioned configuration, the arrangement area of the injection nozzle 91 attached to the injection port 58 (the area marked with hatching in FIG. 7 or FIG. 8 ) can be included in the side wall 70 b of the inner box 70 including the protruding portion 73 or 83 . the structure of the area within. Thereby, the location which becomes the flow obstruction of a heat insulating material can be reduced in the injection path 71 or 81 of the heat insulating material on the back side of the heat insulating box 50 (that is, the side close to the injection nozzle 91).

如上所述,根據本實施方式的隔熱箱體50,能夠設為在注入發泡隔熱材料時能夠使發泡隔熱材料在隔熱箱體內更容易流動的構成。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 mentioned above, according to the heat insulation box 50 of this embodiment, when injecting a foam heat insulation material, it can be set as the structure which can make a foam heat insulation material flow more easily in a heat insulation box. Thereby, the thickness reduction of the side part of the heat insulation box 50 can be achieved, and the possibility that the part which is not filled with the foam heat insulating material in the inside of the heat insulation box 50 can be reduced.

<第二實施方式> 接下來,將說明本發明的第二實施方式。圖10是示出第二實施方式涉及的冰箱1所具備的隔熱箱體50的側面部的構成。以下,以與第一實施方式不同的構成為中心進行說明。 <Second Embodiment> Next, a second embodiment of the present invention will be explained. FIG. 10 shows the configuration of the side surface of the heat insulating box 50 included in the refrigerator 1 according to the second embodiment. Hereinafter, the configuration different from that of the first embodiment will be mainly described.

如圖10所示,在隔熱箱體50的側面部設置有控制隔熱材料的流入方向的方向控制部175。方向控制部175配置在將伸出部73向前方方向延伸的部位。在本實施方式中,方向控制部175配置在內箱70的側面壁70b的內側(設置有隔熱材料的一側)。由此,在配置有方向控制部175的部分,隔熱箱體50內的空間變窄。As shown in FIG. 10, the side surface part of the heat insulation box 50 is provided with the direction control part 175 which controls the inflow direction of a heat insulating material. The direction control portion 175 is arranged at a portion extending the extension portion 73 in the forward direction. In this embodiment, the direction control part 175 is arrange|positioned inside the side wall 70b of the inner box 70 (the side in which the heat insulating material is provided). Thereby, the space in the heat insulation box 50 becomes narrow in the part where the direction control part 175 is arrange|positioned.

圖11中示意地示出向本實施方式涉及的隔熱箱體50內注入隔熱材料的情形。圖11中示出在隔熱箱體50的上方側的注入口58安裝有注入噴嘴91的狀態,用箭頭表示從注入噴嘴91排出的隔熱材料的流入方向。FIG. 11 schematically shows a state in which a heat insulating material is injected into the heat insulating box 50 according to the present embodiment. 11 shows a state in which the injection nozzle 91 is attached to the injection port 58 on the upper side of the heat insulation box 50, and the inflow direction of the heat insulating material discharged from the injection nozzle 91 is indicated by an arrow.

方向控制部175由在側視時具有大致三角形的三棱柱狀的物體形成。該方向控制部175例如能夠由發泡苯乙烯等形成。如圖11所示,三角形狀的方向控制部175的頂點部分位於向前方方向延長伸出部73的位置。The direction control portion 175 is formed of a triangular prism-shaped object having a substantially triangular shape in a side view. The direction control portion 175 can be formed of, for example, foamed styrene or the like. As shown in FIG. 11 , the apex portion of the triangular-shaped direction control portion 175 is located at a position where the extension portion 73 is extended in the forward direction.

通過設置這樣的方向控制部175,如在圖11中虛線的箭頭所示,變更隔熱材料的流入方向。即,從注入噴嘴91排出的隔熱材料通過設置在隔熱箱體50的側面部的伸出部73流向前方側(開口部50a)後,到達方向控制部175的設置位置。By providing such a direction control part 175, as shown by the arrow of a broken line in FIG. 11, the inflow direction of a heat insulating material is changed. That is, the heat insulating material discharged from the injection nozzle 91 flows to the front side (opening part 50 a ) through the extension part 73 provided on the side surface of the heat insulating box 50 , and then reaches the installation position of the direction control part 175 .

在此,方向控制部分175成為隔熱材料的流動的分流點,並且隔熱材料沿著箭頭A的方向和箭頭B的方向分開流動。例如,在具有圖11所示形狀的方向控制部分175的情況下,可以向箭頭A的方向流入更多的隔熱材料。Here, the direction control portion 175 becomes a branch point of the flow of the heat insulating material, and the heat insulating material flows in the direction of arrow A and the direction of arrow B separately. For example, in the case of the direction control portion 175 having the shape shown in FIG. 11 , more heat insulating material may flow in the direction of the arrow A. As shown in FIG.

如上所述,本實施方式涉及的隔熱箱體50設置方向控制部分175。由此,適當地變更流入隔熱箱體50的開口部50a側的隔熱材料的流動和流量,例如,可以通過隔熱箱體50內的規定部分使更多的隔熱材料流入。As described above, the heat insulation box 50 according to the present embodiment is provided with the direction control section 175 . Thereby, the flow and flow rate of the heat insulating material flowing into the opening 50a side of the heat insulating box 50 can be appropriately changed, for example, more heat insulating materials can be made to flow through a predetermined portion in the heat insulating box 50 .

另外,與下方的注入口58對應的伸出部83配合收納容器保持部23的形狀,延伸到隔熱箱體50的開口部50a的附近。因此,在伸出部83的前方側沒有設置方向控制部。但是,在其他實施方式中,也可以在與下方的注入口58對應的伸出部83的前方側設置方向控制部。Moreover, the extension part 83 corresponding to the lower injection port 58 is extended to the vicinity of the opening part 50a of the heat insulation box 50 according to the shape of the container holding part 23. Therefore, no direction control portion is provided on the front side of the overhang portion 83 . However, in other embodiments, the direction control portion may be provided on the front side of the overhang portion 83 corresponding to the lower injection port 58 .

在本實施方式涉及的冰箱1中,除了方向控制部分175之外的配置可以應用與第一實施例相同的配置。In the refrigerator 1 according to the present embodiment, the configuration other than the direction control portion 175 can be applied to the same configuration as that of the first embodiment.

<第三實施方式> 接著,對本發明的第三實施方式進行說明。在第三實施方式中,控制隔熱材料的流入方向的方向控制部的構成與第二實施方式不同。對於除此之外的構成,可以應用與第二實施方式相同的構成。因此,在第三實施方式中,以與第二實施方式的不同點為中心進行說明。 <Third Embodiment> Next, a third embodiment of the present invention will be described. In the third embodiment, the configuration of the direction control unit that controls the inflow direction of the heat insulating material is different from that of the second embodiment. For the configuration other than this, the same configuration as that of the second embodiment can be applied. Therefore, in the third embodiment, the difference from the second embodiment will be mainly described.

圖12中示意地示出第三實施方式涉及的冰箱1的隔熱箱體50內注入隔熱材料的情形。圖12中示出在隔熱箱體50的上方側的注入口58安裝有注入噴嘴91的狀態,用箭頭表示從注入噴嘴91排出的隔熱材料的流入方向。FIG. 12 schematically shows a state in which a heat insulating material is injected into the heat insulating box 50 of the refrigerator 1 according to the third embodiment. 12 shows a state where the injection nozzle 91 is attached to the injection port 58 on the upper side of the heat insulation box 50, and the inflow direction of the heat insulating material discharged from the injection nozzle 91 is indicated by an arrow.

如圖12所示,在隔熱箱體50的側面部設置有控制隔熱材料的流入方向的方向控制部275。方向控制部275配置在將伸出部73向前方方向延伸的部位。在本實施方式中,方向控制部275向伸出部73的開口側進一步擴展而形成。即,方向控制部275與伸出部73同樣,形成為向箱內側隆起的形狀。As shown in FIG. 12, the side surface part of the heat insulation box 50 is provided with the direction control part 275 which controls the inflow direction of a heat insulating material. The direction control portion 275 is arranged at a portion extending the extension portion 73 in the forward direction. In the present embodiment, the direction control portion 275 is formed to be further expanded toward the opening side of the extension portion 73 . That is, the direction control part 275 is formed in the shape which protrudes toward the box inner side similarly to the extension part 73. FIG.

通過設置這樣的方向控制部275,如在圖12中虛線的箭頭所示,變更隔熱材料的流入方向。即,從注入噴嘴91排出的隔熱材料通過設置在隔熱箱體50的側面部的伸出部73流向前方側後,到達方向控制部275。然後,沿著方向控制部275的形狀,以向箭頭B的方向擴展的方式流動。由此,能夠使更多的隔熱材料向箭頭B的方向流入。By providing such a direction control part 275, as shown by the arrow of a broken line in FIG. 12, the inflow direction of a heat insulating material is changed. That is, the heat insulating material discharged from the injection nozzle 91 flows to the front side through the extension portion 73 provided in the side surface portion of the heat insulating box 50 , and then reaches the direction control portion 275 . Then, it flows so as to expand in the direction of arrow B along the shape of the direction control portion 275 . Thereby, more heat insulating material can be made to flow in the direction of arrow B.

在本實施方式中,也優選與第一實施方式同樣地以伸出部73的上表面成為水準的方式形成。在這種情況下,也能夠將擱板等滑動自如地載置於伸出部73的上表面。另外,也可以以伸出部73的前端成為稍微向上的傾斜面的方式形成。由此,能夠使沿箭頭A的方向流動的隔熱材料流入上側。另外,通過形成該向上的傾斜面,能夠作為止動件發揮功能,防止載置於伸出部73的上表面的擱板不小心地向前方滑動移動。Also in this embodiment, it is preferable to form so that the upper surface of the extension part 73 may become level similarly to 1st Embodiment. Even in this case, the shelf or the like can be slidably placed on the upper surface of the extension portion 73 . In addition, it may be formed so that the front end of the extension part 73 may become a slightly upward inclined surface. Thereby, the heat insulating material flowing in the direction of the arrow A can be made to flow into the upper side. Moreover, by forming this upward inclined surface, it can function as a stopper, and can prevent the shelf board mounted on the upper surface of the extension part 73 from sliding forward inadvertently.

如上所述,本實施方式涉及的隔熱箱體50設置方向控制部分275。由此,適當地變更流入隔熱箱體50的開口部50a側的隔熱材料的流動和流量,例如,可以通過隔熱箱體50內的規定部分使更多的隔熱材料流入。As described above, the heat insulation box 50 according to the present embodiment is provided with the direction control portion 275 . Thereby, the flow and flow rate of the heat insulating material flowing into the opening 50a side of the heat insulating box 50 can be appropriately changed, for example, more heat insulating materials can be made to flow through a predetermined portion in the heat insulating box 50 .

此外,在與下方的注入口58對應的伸出部83中,也可以設置與上述同樣的方向控制部275。In addition, the direction control part 275 similar to the above may be provided in the protruding part 83 corresponding to the lower injection port 58 .
