Description

冰箱 技术领域
本发明涉及一种冰箱。
背景技术
一般来说，冰箱具有在外箱与内箱之间填充隔热材料的结构，但即使有隔热材料，有时候内箱内的冷气也会传递至外箱。此时，外箱周边的空气因为外箱内外的温度差而被冷却，外箱表面产生凝露。
为了防止所述凝露，例如将流通因压缩机的压缩而升温的制冷剂气体的热气管嵌入隔热材料。与此相关，下述专利文献1中记载有：将热气管埋设在分隔冰箱内的各储藏室的分隔壁与分隔外板之间填充的隔热材料内。专利文献1中虽未提及，但从热传导性高的观点出发，一直以来使用的热气管通常为铜制。
专利文献1：JP特开平10-122730号公报。
热气管大多为铜制。但是，相对来说，铜是昂贵金属，铜制热气管是冰箱成本上升的主要因素。因此，为了降低产品成本，尝试将热气管从铜制变成铁制。
但是，例如，如图5所示，配置在常规使用的热气管的分隔壁正面61与分隔外板(未图示)之间的部分50的形状如下：起始端51从冰箱外廓的侧壁其中一侧21延伸出来，向冰箱外廓的侧壁另一侧22延伸，并在预定部位(例如折返部52)折返，再次向冰箱外廓的侧壁其中一侧21延伸而直至终端53。
在铜制热气管50的情况下，由于铜具有相应的弹性，因此热气管良好地接触覆盖分隔壁正面61的分隔外板。从而缓和外箱内外的温度差，有效发挥防凝露功能。但是，若将热气管50的材料从铜替换为铁，由于铁的弹性比铜低，因此在如上所述设置一个折返部52的形状下，会发生热气管50未充分接触分隔外板的状况。因此，会阻碍外箱表面的防凝露功能。
为了消除此问题，在热气管50与分隔外板之间插入例如像丁基橡胶这样的热传导性良好的弹性体，但是设置丁基橡胶会增加产品的成本。
发明内容
本发明的目的在于提供一种冰箱，即使在分隔壁与分隔外板之间的空间配置铁制热气管的情况下，也能使热气管与分隔外板良好地接触，恰当地发挥防凝露功能。
为了解决前述课题，本发明所涉及的一种冰箱，包括：
隔热箱体，包括内箱、外箱、及填充于所述内箱与所述外箱之间的隔热材料；及
铁制热气管，配置为与所述外箱相接触，其中流通作为热源的制冷剂；且
所述铁制热气管具备第一折返部及第二折返部，
至少部分所述第一折返部及第二折返部与所述外箱的预定部位相接触。
进而，所述铁制热气管还具备分隔壁前部区域配置部，
所述分隔壁前部区域配置部位于将在高度方向相邻设置的各储藏室分隔的隔热分隔壁正面部、与覆盖所述隔热分隔壁正面部的正面部盖板之间，
所述第一折返部及第二折返部设置在所述分隔壁前部区域配置部中，且所述第一折返部、第二折返部分别与所述正面部盖板接触。
进而，所述第一折返部配置在所述隔热分隔壁正面部的侧部区域其中一侧，
所述第二折返部配置在所述隔热分隔壁正面部的侧部区域另一侧。
进而，所述分隔壁前部区域配置部的起始端位于所述隔热箱体的侧壁其中一侧，
所述分隔壁前部区域配置部的终端位于所述隔热箱体的侧壁另一侧，
所述分隔壁前部区域配置部从所述起始端经由所述第一折返部及所述第二折返部而到达所述终端，
所述第一及第二折返部挤压所述正面部盖板。
进而，所述铁制热气管还包括横穿隔热分隔壁正面部的前方区域的三个直状部位，三个直状部位隔开规定间隔而在上下方向依次排列。
进而，外箱包括第一侧壁、与第一侧壁相对设置的第二侧壁，所述冰箱还包括位于机械室内的压缩机，
所述铁制热气管从压缩机延伸出来，从冰箱的后部进入第一侧壁的内侧，到达第一侧壁前缘后，向上方侧弯曲；弯曲后的热气管达到隔热分隔壁的高度后，第二侧壁方向弯曲；进而，热气管穿过与隔热分隔壁的正面部面对的前方区域而向第二侧壁前进，并与行进方向相反地二次折返后，到达第二侧壁前缘；到达第二侧壁前缘的热气管进而向冰箱的底部弯曲，到达第二侧壁前缘的底端；然后，热气管向冰箱后方进一步弯曲，返回到机械室。
发明效果
根据本发明所涉及的冰箱，即使在隔热分隔壁与正面部盖板之间的空间配置铁制热气管的情况下，也能使热气管与正面部盖板良好地接触，从而恰当地发挥防凝露功能。此外，由于热气管为铁制，从而与铜制热气管相比，可以降低产品成本。
此外，根据本发明所涉及的冰箱，由于具备第一折返部及第二折返部的热气管的分隔壁前部区域配置部位于隔热分隔壁正面部与正面部盖板之间，因此可缓和正面部盖板内外的温度差，从而有效地防止其外侧凝露。
进而，根据本发明所涉及的冰箱，第一折返部配置在隔热分隔壁正面部的侧部区域其中一侧，第二折返部配置在隔热分隔壁正面部的侧部区域另一侧，因此可以遍及宽度方向而大范围地确保热气管的分隔壁前部区域配置部与正面部盖板的热接触区域。由此，可以更大范围地防止正面部盖板凝露。
进而，根据本发明所涉及的冰箱，分隔壁前部区域配置部的起始端位于隔热箱体侧壁的其中一侧，分隔壁前部区域配置部的终端位于隔热箱体侧壁的另一侧，分隔壁前部区域配置 部从所述起始端经由所述第一折返部及所述第二折返部而到达所述终端，第一及第二折返部挤压正面部盖板，因此，可以使热气管的分隔壁前部区域配置部与正面部盖板更良好地热接触。结果，可以更有效地发挥热气管的防凝露功能。

具体实施方式
以下，参照附图详细地说明本发明的一实施方式所涉及的冰箱1。另外，说明本实施方式所涉及的冰箱1时，“上下”方向对应于冰箱1的高度方向，“左右”方向对应于冰箱1的宽度方向，“前后”方向对应于冰箱1的深度方向。
首先，参照图1来说明本实施方式所涉及的冰箱1的整体构成。在此，图1是冰箱1的侧视垂直剖视图。如图所示，本实施方式所涉及的冰箱1具备相当于冰箱主体的隔热箱体2。隔热箱体2具备多个储藏室，其内部储藏食品等。此外，虽然没有特别限定，但多个储藏室从上到下分别对应冷藏室3、冷冻室4。
隔热箱体2内设置的各储藏室在前表面开口。设置隔热门D1、D2以便可以打开或关闭各开口。在此，例如前视冰箱时，隔热门D1右端的上下端部可转动地被隔热箱体2支承，关闭冷藏室3的前表面开口。此外，隔热门D2配置成可相对于隔热箱体2在前后方向拉开，关闭冷冻室4的前表面开口。
进而，隔热箱体2具备钢板制外箱2a、合成树脂制内箱2b、及外箱与内箱之间形成的间隙内填充的发泡聚氨酯(聚氨酯泡沫)制隔热材料2c。在隔热箱体2的内部，配置有隔热分隔壁(例如图1的符号6表示的构件)。利用该隔热分隔壁6分隔出冷藏室3与冷冻室4。
此外，在外箱2a与内箱2b之间的空间内，以嵌入隔热材料2c的方式设置内部中空的铁制热气管10。热气管10配置在冰箱后部底部的机械室M的压缩机C开始延伸，其中流通被压缩机C压缩而升温的制冷剂。
其次，参照图2来说明所述热气管10的配置状态。在此，图2是表示冰箱外箱2a的两侧壁21、22与热气管10的位置关系的图。另外，图2所示的冰箱1处于没有内箱2b及隔 热材料2c的状态。实际的冰箱1中，设置在外箱2a附近的热气管10的部分穿过隔热材料2c。
从机械室M内的压缩机C延伸出来的热气管10例如从冰箱1的后部进入外箱2a的第一侧壁21的内侧，到达第一壁前缘211后，向上方侧弯曲。弯曲后的热气管10达到接近隔热分隔壁6的高度后，向右侧(图的左侧)弯曲。
进而，热气管10穿过与隔热分隔壁6的正面部61(后述图3中图示)面对的前方区域而向外箱2a的第二侧壁22前进，并与行进方向相反地二次折返后，到达第二侧壁前缘221。另外，以下，将通过隔热分隔壁6(正面部61)的前方区域的热气管10的部分称为“分隔壁前部区域配置部110”。
到达第二侧壁前缘221的热气管10进而向冰箱的底部弯曲，到达第二侧壁前缘221的底端。然后，热气管10向冰箱后方进一步弯曲，返回到冰箱后部底部的机械室M。
另外，图2中虽然省略了图示，但钢板制的正面部盖板62是以覆盖隔热分隔壁正面部61的方式配置(参照图1)。由此，热气管10的分隔壁前部区域配置部110也被正面部盖板62覆盖。另外，正面部盖板62构成冰箱1的外廓，因此，以下说明中将其视作冰箱外箱2a的一部分。
热气管10的配置方法并不限定于此，本实施方式的热气管10仅配置在冰箱1的底部侧储藏室(本实施方式为冷冻室4)、及其正上方的隔热分隔壁6的周围。即，热气管10并不穿过冰箱1的上方侧储藏室(本实施方式为冷藏室3)的周围。由此，可以相对缩短热气管10的长度。结果，可减少金属制构件的使用量，降低产品成本。
其次，参照图3及图4，详细说明本实施方式所涉及的热气管10。在此，图3是表示隔热分隔壁6(正面部61)及热气管10(分隔壁前部区域配置部110)的正面放大图。此外，图4是表示热气管10(分隔壁前部区域配置部110)与正面部盖板62的接触状态的箭视图(图4(a)是从图3的箭头A观察的箭视图，图4(b)是从图3的箭头B观察的箭视图)。
如图3所示，热气管10的分隔壁前部区域配置部110从位于隔热箱体2的侧壁其中一侧21(第一侧壁)附近的起始端110S开始向图3的左侧延伸，到达侧壁另一侧22(第二侧壁)附近后，向其延伸方向的反方向折返。将该折返部位称为“第一折返部111”。
在第一折返部111折返的热气管10的分隔壁前部区域配置部110向图的右侧延伸，到达侧壁其中一侧21附近后，再次向延伸方向的反方向折返。将该折返部位称为“第二折返部112”。在第二折返部112折返的热气管10的分隔壁前部区域配置部110向图的左侧延伸，到达位于侧壁另一侧22附近的终端110E。另外，本实施方式中，形成了两个折返部，但折返部的数量并不限定于此。
在这种状态下配置热气管10的分隔壁前部区域配置部110，因此，如图3所示，横穿各隔热分隔壁正面部61的前方区域的合计三个直状部位113、114、115隔开规定间隔而在上下方向依次排列。即，与图5所示的现有的热气管50相比，可以增加与正面部盖板62 的接触区域。因此，可以进一步缓和正面部盖板62内外的温度差，从而有效地防止正面部盖板62外侧凝露。
在此，本实施方式中，起始端110S及终端110E是以在固定端向延伸方向的反方向折返的第一折返部111及第二折返部112产生向前力的状态下，收纳在隔热分隔壁正面部61与正面部盖板62之间。
因此，如图4(a)及图4(b)所示，第一折返部111及第二折返部112以及它们附近的部位挤压正面部盖板62。结果，热气管10的分隔壁前部区域配置部110可经由第一折返部111及第二折返部112而与正面部盖板62良好地接触。
通过这样的结构，热气管10的热良好地被传递给正面部盖板62，从而可防止其外侧产生凝露。即，即使像本实施方式这样，将热气管10从现有的铜制变更为铁制，也能与正面部盖板62良好地热接触。由此，可以有效地降低产品成本。
以上，对本发明的实施方式进行了详细说明。但，所述说明是为了容易理解本发明而描述的，并不旨在限定本发明。本发明可在不脱离其主旨的情况下包含各种变更、改良。此外，本发明包含其等价物。
