回气管220可包括回气软管221以及与回气软管221连接的回气铜管222，进气管210可包括进气软管211以及进气铜管212，进气软管211和回气软管221至少从门体120一侧的铰链轴132延伸至箱体110一侧，从而不会阻碍门体120的开关且软管韧性较大，不易因门体120转动而损坏，而进气铜管212和回气铜管222又能保证较好的换热效果。
具体的，进气管210可包括置于门体120一侧的进气铜管和置于箱体110一侧 的进气铜管212，门体120一侧的进气铜管可埋设在门体120的隔热层内，进气软管211的两端可分别连接门体120一侧的进气铜管和箱体110一侧的进气铜管212。进气软管211可自门体120一侧的铰链轴穿入门体120的门轴内，在门体120的门轴内与门体120一侧的进气铜管连接，也可直接伸入门体120的隔热层内，在门体120的隔热层内与门体一侧的进气铜管连接。箱体110一侧的进气铜管212的可与压机仓内的冷凝器240连接，门体120一侧的进气铜管可与门体毛细管250。
回气铜管222也包括置于箱体110一侧的回气铜管222和置于门体120一侧的回气铜管，箱体110一侧的回气铜管222与压缩机230的制冷剂入口连接，门体120一侧的回气铜管与门体蒸发器260的制冷剂出口连接，回气软管221的两端可分别连接箱体110一侧的进气铜管212和门体120一侧的进气铜管。回气软管221可从门体120一侧的铰链轴穿入门体120的门轴中，在门轴中与门体120一侧的回气铜管连接，回气软管221也可在穿入门轴后进入门体120的隔热层，在门体120的隔热层内与门体120一侧的回气铜管连接。
进一步的，在本发明一实施方式中，箱体110上的管道口111的轴线平行于铰链轴132的轴线，铰链盖板131覆盖铰链轴132以及管道口111。
在本实施方式中，回气管220和进气管210可同时从门体120的铰链轴132穿出后从管道口111穿入箱体110内部，管道口111的轴线平行于铰链轴132，在门体120转动过程中可减小对回气管220和进气管210的损伤。
进气软管211和回气软管221均从门体120一侧的铰链轴132穿出后从管道口111穿入箱体110隔热层内并穿至压机仓内分别与压机仓内的进气铜管212和回气铜管222连接。冰箱100内还可以设置有供水装置，供水装置可向制冰间室内的制冰装置供水，供水装置的水管也可从门体120隔热层经门体120一侧的铰链轴132穿出后通过管道口111进入箱体110隔热层内，水管、回气软管221以及进气软管211可形成一个管束，方便安装制造。且箱体110一侧回气软管221与回气铜管222的接口、进气软管211与进气铜管212的接口均设置在压机仓内，无需在箱体110上设置额外的连接空间，铰链盖板131直接覆盖门体120一侧的铰链轴132和管道口111之间的区域即可实现回气管220防凝露，整体结构紧凑。
参见图4，在本发明另一实施方式中，箱体110上设置有管路容纳槽112以及封闭管路容纳槽112的隔热盖113，管道口111可设置在管路容纳槽112内。进气铜管212以及回气铜管222均自压机仓穿入箱体110的隔热层内并从箱体110上的管道口111穿出后分别与进气软管211与回气软管221连接。进气软管211与进气铜管212 的接口以及回气软管221与回气铜管222的接口均设置在管路容纳槽112内。
在本实施方式中，箱体110顶部内凹形成管路容纳槽112，管道口111设置在管路容纳槽112的侧壁上，隔热盖113与铰链盖板131可分离设置，回气软管221自门体120铰链轴132穿入铰链盖板131内，再从铰链盖板131穿出进入隔热盖113内，隔热盖113与铰链盖板131共同包覆门体120一侧铰链轴132与管道口111之间的回气管220。隔热盖113为铰链盖板131的一部分，隔热盖113也可与铰链盖板131一体成型，如此，安装制造更加方便。
如此，由于软管的价格比铜管价格高，如此设置可以减少软管的长度，降低生产制造成本，且方便安装制造。
参见图5，在本发明另一实施例中，至少门体120一侧铰链轴132与箱体110的管道口111之间的回气软管221的管壁内埋设有加热丝223。回气软管221至少从门体120一侧的铰链轴132延伸至箱体110一侧以避免回气管220阻碍门体120的开闭，延长回气管220的使用寿命。
加热丝223可以从回气软管221一端的端面穿出与线束连接，线束可穿入冰箱100的箱体110或门体120内侧与冰箱100的控制板连接，控制板可控制加热丝223的开闭，如可仅在压缩机230工作向门体蒸发器260供应制冷剂时，开启加热丝223。
回气软管221置于门体120一侧的铰链轴132和箱体110的管道口111之间的部分裸露于外界环境中，因流经回气软管221的制冷剂为低温制冷剂，所以回气软管221外侧容易产生凝露。而通过在此部分的回气软管221的管壁中埋设加热丝223，加热丝223与回气软管221一体成型，能够解决回气软管221的凝露问题，同时，加热丝223埋设在回气软管221的管壁内，整体占用空间小，且安装时方便，回气软管221的关闭能够对加热丝223起到保护作用，同时加热丝223的韧性较高，也可增强回气软管221的韧性，增加回气软管221的寿命。
进一步的，在本发明一实施方式中，回气软管221的管壁内埋设有与回气软管221等长的加热丝223，也就是整个回气软管221的管壁内均埋设有加热丝223，从而制造更加方便，且防凝露效果更好。
加热丝223包括沿回气管220周侧间隔设置的多条电阻丝，电阻丝的韧性较好，不易断裂，且能够更好的提升回气软管221的韧性。多条电阻丝沿回气管220的周侧间隔设置，任意两条相邻的电阻丝之间的间距可相等，可以使得回气管220受热更加均匀，提升防凝露效果。
参见图6、图7，为本发明提供的又一实施例的冰箱100，在本实施例中，制冷 系统200的压缩机230和冷凝器240安装在箱体110一侧的压机仓内，门体毛细管250和门体蒸发器260均安装在门体120内，如此，在制冷过程中流经冷凝器240和门体毛细管250之间的进气管210的制冷剂为常温制冷剂，进气管210不会出现凝露问题。
在本实施方式中，进气管210和回气管220均从门体120一侧的铰链轴132穿出经过箱体110的管道口111穿入箱体110的隔热层内。进气管210包括至少从门体120一侧铰链轴132延伸至箱体110一侧的进气软管211，回气管220包括至少从门体120一侧铰链轴132延伸至箱体110一侧的回气软管221，且至少门体120一侧铰链轴132与管道口111之间的回气软管221置于进气软管211内。
门体120一侧铰链轴132与管道口111之间的回气软管221内的制冷剂为低温制冷剂，若回气软管221直接暴露在外界环境中，回气软管221可能产生凝露。将回气软管221设置在进气软管211内部，能够避免回气软管221直接暴露在外部环境中，且回气软管221外侧同时被进气软管211和常温的制冷液包裹，回气软管221不会出现凝露，且整体结构紧凑，不会占用额外的空间，进气软管211和回气软管221相互嵌套也不会影响门体120开关和管路寿命。
进一步的，回气管220包括与回气软管221连接的回气铜管222，进气管210包括与进气软管211连接的进气铜管212，回气软管221整体置于进气软管211内部，从而方便连接制造也可提升防凝露效果。
回气软管221和进气软管211可一体成型，回气软管221和进气软管211之间可设置有支撑筋224，从而使得回气管220相对进气管210固定，回气管220和进气管210之间的管路相对固定，来自压缩机230的制冷剂可顺畅的通过进气管210和回气管220之间的通道进入门体毛细管250内，不会影响制冷效果，同时，支撑筋224也可增强整体结构的稳定性和管路的强度，方便安装制造。
进一步的，在本发明一实施方式中，冰箱100还包括分流连接件300，分流连接件300连接进气软管211、进气铜管212、回气软管221和回气铜管222。分流连接件300可包括置于箱体110的一侧的分流连接件300和置于门体120一侧的分流连接件300。在制冷过程中，来自压缩机230的制冷剂从进气铜管212通过分流连接件300进入进气软管211内部然后在通过分流连接件300进入门体120一侧的进气铜管，流经门体毛细管250和门体蒸发器260后流入门体120一侧的回气铜管，再经过门体120一侧的分流连接件300进入回气软管221，通过箱体110一侧的分流连接件300后进入箱体110一侧的回气铜管222并返回压缩机230内。
分流连接件300包括流体腔310以及贯通流体腔310的进气软管连接部320和回气管连接部330。进气软管211的端部连接于进气软管连接部320，回气软管221自进气软管连接部320一侧穿过流体腔310与回气管连接部330连接，回气软管221与流体腔310的侧壁之间形成与进气软管211连通的进气腔体，分流连接件300还包括贯通流体腔310的进气铜管连接部330，进气铜管212连接于进气铜管连接部340。
在本实施方式中，流体腔310呈圆柱形，且流体腔310的内径大于回气管软管221的外径，流体腔310的两端端面开口，分别设置有与进气软管211连接的进气软管连接部320和与回气管220连接的回气管连接部330，流体腔310的侧壁上开口形成用于连接进气铜管212的进气铜管连接部340。回气铜管222可直接与回气软管221连接，也可通过回气管连接部330连接于回气软管221。图6为箱体一侧的分流连接件连接示意图，图示中箭头代表制冷剂流向，在制冷过程中，制冷剂从进气铜管212流入回气软管221与流体腔310之间的进气腔体后直接流入进气软管211与回气软管221之间，而回气软管221内的制冷剂可直接流入与之连接的回气铜管222内。
回气管连接部330可包括置于流体腔310一侧的连接管套331，回气软管221穿过所述流体腔310置于所述连接管套331内，回气软管221与连接管套331过盈配合，回气铜管222可置于所述回气软管221内与回气软管221过盈配合。具体的，回气铜管222和回气软管221均可置于连接管套331内，且回气铜管222置于回气软管221内，即从外到内依次为连接管套331、回气软管221、回气铜管222，并通过机械压合的方式使得连接管套331、回气软管221、回气铜管222相互过盈配合。
进气软管连接部320包括螺纹连接套321，螺纹连接套321的一端与进气软管211配合，另一端通过螺纹连接于流体腔310的外壁。在本实施方式中，螺纹连接套321与进气软管211可配合，也可通过螺纹连接。进气软管211的端部以及螺纹连接套321均套设在流体腔310外壁，流体腔310的外壁上设置有外螺纹，螺纹连接套321上设置有内螺纹，安装时，通过螺纹连接套321即可将进气软管211连接在分流连接件300上。进气铜管连接部340可为开设在流体腔310侧壁上的开口，进气铜管212可通过金属胶直接粘合在进气铜管连接部340。
进一步的，在本发明一实施方式中，箱体110一侧的分流连接件300置于箱体110一侧的压机仓。在本实施方式中，进气软管211和回气软管221均自门体120一侧的铰链轴132穿出后经箱体110上的管道口111穿过箱体110的隔热层进入箱体 110一侧的压机仓内，进气软管211和回气软管221在压机仓内通过分流连接件300与进气铜管212和回气铜管222连接。
在本实施方式中，在制造过程中仅需要从箱体110内穿设一根制冷剂管，制造简单，且回气管220置于进气管210内直接从箱体110上的管道口111穿入发泡层内，回气管220不存在任何裸露在外侧的部分，不会出现凝露现象，无需额外设置其他结构。
在本发明另一实施方式中，箱体110上设置有管路容纳槽112以及封闭管路容纳槽112的隔热盖113，分流连接件300置于管路容纳槽112内，进气铜管212和回气铜管222均自压机仓穿过箱体110的隔热层从管道口111穿入管路容纳槽112内与分流连接件300连接，回气软管221和进气软管211均从门体120一侧的铰链轴132延伸至箱体110一侧与分流连接件300连接。
在本实施方式中，减少了回气软管221和进气软管211的长度，可以降低成本，但在分流连接件300处可能会出现凝露现象，因此，在箱体110上设置管路容纳槽112并使用隔热盖113密封封闭管路容纳槽112，将分流连接件300置于管路容纳槽112中，可避免分流连接件300处出现凝露。
