Description

一种冰箱及其制造方法 技术领域
本发明涉及一种在储藏室内冷却保存食品等的冰箱及其制造方法，特别是涉及一种具备隔热门的冰箱及其制造方法，所述隔热门在其上部具有盖部件。
背景技术
通常，在冰箱中，在隔热箱体的内部形成有冷藏室等储藏室，该冷藏室由隔热门从前方封闭。另外，隔热门在宽度方向上的一端通过铰链机构可自由转动地安装在隔热箱体上。
专利文献1(日本特开2013-68390号公报)中记载有将冰箱门可转动地安装在隔热箱体上的结构。参照该文献，在箱门的上端形成有铰链孔，而与冰箱主体连接的垫圈板配设于铰链孔的上方。另外，在垫圈板的孔部和铰链孔中穿过有筒状的支撑部件。通过这种结构，箱门可转动地安装在冰箱主体上。另外，通常在箱门的铰链孔和主体的铰链轴之间配设有铰链环。
发明内容
然而，在上述结构的冰箱中，为了防止隔热材料从门的内部向外部漏出而采用了铰链环，但是铰链环的采用会导致成本增加的问题。
另外，为了防止隔热材料从铰链孔向外部漏出，可以考虑用胶带将铰链孔封闭。然而，在用胶带将铰链孔封闭的结构中，在隔热材料发泡的工序中的压力有时会使胶带破损，可能会无法充分地防止隔热材料从铰链孔漏出。
本发明鉴于上述问题而完成，其目的在于提供一种不使用铰链环而将隔热门安装在隔热箱体上的冰箱及其制造方法。
本发明的冰箱包括：形成有储藏室的隔热箱体、可转动地安装在所述隔热箱体上并将所述储藏室封闭的隔热门、将所述隔热门可转动地安装在所述隔热箱体上的铰链机构、以及配设于所述隔热门上端的上端盖部件，其中，所述上端盖部件包括局部成凹状的收纳部、以及形成于所述收纳部的铰链孔，所述铰链机构包括安装在所述隔热箱体上的铰链板、以及竖直安装在所述铰链板上并可转动地插入所述铰链孔中的铰链轴，所述铰链机构的所述铰 链板收纳在形成于所述上端盖部件上的所述收纳部中，所述铰链孔的内侧开口部通过由合成树脂构成的盖部件封闭。
另外，在本发明的冰箱中，所述盖部件通过连接部与所述上端盖部件一体成形。
本发明的冰箱的制造方法，包括：将外侧板材、内侧板材、下端盖部件及上端盖部件组合来构成隔热门，在所述隔热门上形成内部空间的工序；将发泡隔热材料发泡填充到所述隔热门的所述内部空间填充的工序；以及将铰链机构的铰链轴插入形成于所述隔热门的所述上端盖部件上的铰链孔，并将所述隔热门可转动地装配到隔热箱体的工序，其中，在形成所述内部空间的工序中，通过由合成树脂构成的盖部件将形成于所述上端盖部件上的所述铰链孔的内侧开口部封闭。
另外，在本发明的冰箱的制造方法中，所述盖部件通过连接部与所述上端盖部件一体成形，所述盖部件在通过所述连接部与所述上端盖部件连接的状态下，将所述铰链孔封闭。

具体实施方式
下面根据附图对本发明的实施例所涉及的冰箱10进行详细地说明。在以下的说明中，上下方向表示冰箱10的高度方向，左右方向表示从前方观察冰箱10的情形，前后方向表示冰箱10的进深方向。
参照图1，对冰箱10的概略结构进行说明。图1(A)是从左前方观察本发明的实施方式所涉及的冰箱10的立体图，图1(B)是用于表示本发明的实施方式所涉及的冰箱10的概略结构的侧面剖面图。
如图1(A)所示，冰箱10具有作为主体的隔热箱体11，该隔热箱体11的内部形成有储藏食品等的储藏室。另外，作为储藏室，从上层开始，形成有冷冻室15(参照图1(B))及冷藏室16(参照图1(B))。
隔热箱体11的各个储藏室的前面开口，在上述开口上可自由开闭地设有隔热门17及隔热门18。隔热门17右端侧(从前方看)的上下端部可自由转动地由隔热箱体11支撑，从前方可自由开闭地对冷冻室15的开口进行封闭。同样，隔热门18右端(从前方看)的上下端部可自由转动地由隔热箱体11支撑，从前方可自由开闭地对冷藏室16的开口进行封闭。
如图1(B)所示，作为冰箱10的主体的隔热箱体11包括前面开口的钢板制的外箱12、以及与该外箱12的内部留有间隙地进行配设且前面开口的合成树脂制的内箱13。在外箱12和内箱13的间隙中，填充发泡有发泡聚氨酯制的隔热材料14。另外，封闭冷冻室15及冷藏室16的隔热门17及隔热门18与隔热箱体11相同，也具有隔热结构。
冷冻室15与位于其下层的冷藏室16通过隔热分隔壁23分隔。与上述隔热箱体11相同，隔热分隔壁23也具有隔热结构。
在内箱13的内部、冷冻室15的后方形成有被由合成树脂板等构成的分隔壁29分隔出的冷却室19。在冷却室19的内部配设有用于冷却在冰箱10内循环的空气的蒸发器，即冷却器21。冷却器21通过制冷剂管路(未图示)与压缩机22、散热器(未图示)及毛细管(未图示)连接，构成蒸汽压缩式的制冷循环回路。经冷却器21冷却的冷气被风机20输送至冷冻室15及冷藏室16，从而使冷冻室15冷却至冷冻温度范围内，使冷藏室16冷却至冷蔵温度范围内。
参照图2及图3，对安装在上述冰箱10上的隔热门17的结构进行说明。图2是从前上方观察隔热门17时的分解立体图，图3是从后上方观察隔热 门17时的分解立体图。
如图2及图3所示，隔热门18包括外侧板材26、从后方安装在外侧板材26上的内侧板材25、在内侧板材25的冰箱内侧的一面上呈框状安装的密封垫24、从下方装配在内侧板材25及外侧板材26上的下端盖部件28、以及从上方装配在内侧板材25及外侧板材26上的上端盖部件27。
外侧板材26例如为钢板制板材，形成隔热门18的外观设计面。另外，外侧板材26的左右方向两端部大致向后方弯折而构成隔热门18的侧面部。
内侧板材25由注塑成型的合成树脂构成并构成隔热门17的内侧面。如图3所示，在内侧板材25的内部安装有能够收纳饮料容器等的收纳容器43。
下端盖部件28由注塑成型的合成树脂构成，从下方将由外侧板材26及内侧板材25形成的内部空间封闭。即下端盖部件28构成了隔热门18的底面。
上端盖部件27由注塑成型的合成树脂构成，从下方将由外侧板材26及内侧板材25形成的内部空间封闭。即上端盖部件27构成了隔热门18的顶面。
再次参照图2，上述结构的隔热门17的上方右端部通过铰链机构32可转动地安装在顶板部件37上。另外，隔热门17的下方右端部通过在这里未示出的铰链机构可转动地安装在图1所示的隔热箱体11上。
在这里，虽然未图示，但由内侧板材25、外侧板材26、上端盖部件27、下端盖部件28包围的内部空间内填充有例如由发泡聚氨酯构成的隔热材料。
参照图4，对上端盖部件27和铰链机构32的关联结构进行说明。图4(A)是从后上方观察上端盖部件27的右端部和铰链机构32的立体图。图4(B)是从后上方观察上端盖部件27和铰链机构32分离后状态的立体图。
参照图4(A)，在上端盖部件27的右端部形成有后面向前方凹陷的凹状收纳部30。收纳部30具有能够收纳铰链机构32前方部分的容积。进一步地，收纳部30大致形成为长方体形状。
参照图4(B)，铰链机构32包括铰链板33、铰链轴34、螺钉38。铰链机构32为用于将隔热门17的上方右端部分可转动地安装在图1所示的隔热箱体11上的机构。
铰链板33由例如厚度为2mm～3mm左右的钢板构成。当从上方观察铰链板33时，铰链机构32前方部分向右弯曲。
铰链轴34在铰链板33的前方右侧的端部，由配设于铰链板33的下表面的钢棒构成。铰链轴34的外径与上端盖部件27的铰链孔31的内径相同。
螺钉38在铰链板33后侧的左右两端部，从下方穿过铰链板33。
铰链机构32的铰链轴34以可转动的状态插入到形成于上端盖部件27的收纳部30的内部的铰链孔31中。另外，螺钉38插入到图2所示的顶板部件37的下表面。通过这种结构，铰链板33固定在图1所示的隔热箱体11上。
当隔热门17将图1所示的冷冻室15封闭时，铰链机构32前方部分收纳在上端盖部件27的收纳部30中。通过这种结构，铰链机构32不会显现于冰箱10的外观，能够提高冰箱10整体的外观设计性。
参照图5，对上端盖部件27的结构进行详细说明。图5(A)是从下后方观察上端盖部件27的右端部的立体图，图5(B)是从下后方观察铰链孔31及盖部件35的立体图。图5(C)是图5(A)中剖面线A-A处的剖面图。
参照图5(A)，通过使收纳部30的下表面向下方呈圆筒状突出而形成铰链孔31。在铰链孔31的下端经由连接部36与盖部件35连在一起。盖部件35形成于铰链孔31的左侧。
参照图5(B)，由于铰链孔31呈圆筒状，故形成于铰链孔31下端的开口部40形成为圆形。
盖部件35整体上大致为圆盘形状。通过使盖部件35的下表面中央部向下方呈扁平的圆柱状突出而形成突出部39。其中，铰链孔31的开口部40的直径L10与盖部件35的突出部39的直径L11大致相同。
铰链孔31的下端与盖部件35通过连接部36相连。连接部36形成得比盖部件35要薄。
参照图5(C)，形成于铰链孔31下端的开口部40由盖部件35覆盖。具体而言，盖部件35的突出部39无间隙地嵌入开口部40，由此盖部件35将铰链孔31的开口部40封闭。另外，即使在用盖部件35将铰链孔31的开口部40封闭的状态下，铰链孔31与盖部件35也通过弯折状态的连接部36连在一起。
在本实施方式中，通过将上端盖部件27与铰链孔31形成为一体的树脂成形体，能够不再使用以往所用的铰链环。由此，能够减少构成隔热门17的部件的数量。
并且，用由合成树脂构成的盖部件35将铰链孔31的开口部40封闭，因而能够可靠地封闭铰链孔31的开口部40。由此，在下述的将隔热材料42填充发泡到隔热门17的内部充的工序中，能够防止隔热材料42经由铰链孔31向隔热门17的外部漏出。
另外，如图5(A)所示，盖部件35通过连接部36与铰链孔31的左侧连接。即通过使用模具的注塑成型，能够一并制造上端盖部件27主体、铰链孔31及盖部件35。由此，由于不再需要分别制造用于插入图4(B)所示的铰链轴34的铰链孔31及用于封闭铰链孔31的开口的盖部件35，故能够降低制造成本。
另外，铰链孔31与盖部件35通过薄的连接部36连接。如图5(C)所示，由于所形成的连接部36较薄，故能够容易地使连接部36弯折，进而通过盖部件35将铰链孔31的开口部40封闭。
参照图6至图8，对冰箱10的制造方法进行说明。本实施方式所涉及的冰箱10的制造方法，包括：组装具有内部空间41的隔热门17的工序、将隔热材料42发泡填充到隔热门17的内部空间41的工序、以及将隔热门17可转动地组装到隔热箱体11的工序。
参照图6，首先，准备构成隔热门17的一部分的上端盖部件27。图6(A)是从下后方观察上端盖部件27的立体图。图6(B)是图6(A)中剖面线B-B处的剖面图。图6(C)是图6(A)中剖面线B-B处的剖面图，表示通过盖部件35将铰链孔31封闭时的情况。
参照图6(A)，上端盖部件27为在左右方向上细长地形成的细长部件，由注塑成型所形成的合成树脂构成。通过使上端盖部件27的右端的后面向前方凹陷而形成收纳部30。另外，在收纳部30的下方部分形成有大致为圆筒状的铰链孔31。
参照图6(B)，在铰链孔31的下端侧方，通过薄的连接部36相接有圆板状的盖部件35。另外，在盖部件35的下表面形成有扁平圆柱状的突出部39。以连接部36作为支点，使盖部件35沿纸面上的顺时针方向转动，从而通过盖部件35将铰链孔31的开口部40封闭。在此，用箭头表示盖部件35的转动方向。
参照图6(C)，将盖部件35的突出部39插入到铰链孔31的开口部40中，从而通过连接部36将铰链孔31无间隙地封闭。
接下来，参照图7，将构成隔热门17的各个部件组合。图7是从前方观察构成隔热门17的各个部件的分解示意图。
具体而言，通过组合内侧板材25和外侧板材26而在其内部形成内部空间41。另外，通过上端盖部件27将内侧板材25及外侧板材26的上端开口封闭。另外，通过下端盖部件28将内侧板材25及外侧板材26的下端开口封闭。构成隔热门17的各个部件的接合可以采用粘接、利用螺钉等的紧固、嵌入等方式。
然后，如图8所示，将隔热材料42发泡填充到隔热门17的内部空间41。图8是从前方观察本工序中的隔热门17的图。
在本工序中，通过注入法向隔热门17的内部空间41中填充发泡聚氨酯。具体而言，例如将构成聚氨酯泡沫的原液注入内部空间41中。然后，在内部空间41中使该原液发泡硬化，从而使隔热材料42填充到内部空间41的全部区域。
通过上述工序制得隔热门17。然后，隔热门17通过图4(B)所示的铰链机构32可转动地安装在图1所示的隔热箱体11上。具体而言，将图4(B)所示的铰链机构32的铰链轴34插入上端盖部件27的铰链孔31中。另外，在隔热箱体11上也安装隔热门18等其他部件。经过这样的工序来制造图1所示的冰箱10。
如图6(C)所示，根据本实施方式所涉及的冰箱的制造方法，通过由合成树脂构成的盖部件35将铰链孔31的开口部40封闭，从而能够牢固地将开口部40封闭。由此，能够防止在图8所示的隔热材料42的填充工序中，隔热材料42经由铰链孔31向隔热门17的外部漏出。
另外，参照图6(B)，由于盖部件35与上端盖部件27的主体部一体成形，故无需其他的部件来封闭铰链孔31，能够降低制造成本。
另外，参照图6(B)，由于铰链孔31的下端与盖部件35经由连接部36连在一起，故在生产工序的中途阶段，不会出现盖部件35丢失的情况。从而能够使冰箱生产工序高效化。
本发明并不限于上述实施方式，除此以外，在不脱离本发明的主旨范围内，可进行各种变更实施。
