进一步地，本发明的冷藏冷冻装置，利用定位机构固定气调管路与通气口之间的接合部位，即便储物容器在用户取放物品的过程中偏离原始位置，或者出现晃动，也不会牵连气调管路随之移动。并且当储物容器归位时，可以重新与气调管路建立气路连接。因此，基于本发明的方案，储物容器无需固定不动地设置于储物间室内，气调管路与通气口之间的气路连接并不会制约储物容器的移动，这提高了储物容器的使用便利性。
进一步地，本发明的冷藏冷冻装置，通过设置管状连接件，并使管状连接件的一端连通通气口，另一端连通气调管路，利用管状连接件作为气调管路与通气口之间的接合部位，巧妙地连通气调管路与通气口，气调管路的端口与通气口之间并不需要直接地密封结合，这有利于简化冷藏冷冻装置的储物空间与气调管路之间的连通方式。
进一步地，本发明的冷藏冷冻装置，当通气口为中空柱状并至少部分地伸入中空筒状通道内且嵌套于管状连接件的第一连接部所限定出的中空筒状通道之内时，沿远离管状连接件的方向移动储物容器，可使通气口脱出第一连接部所限定出的中空筒状通道，沿靠近管状连接件的方向移动储物容器，可使通气口重新嵌套于第一连接部所限定出的中空筒状通道之内，因此，基于上述结构，可使储物容器与气调管路之间以可拆卸的方式实现气路连接。
更进一步地，本发明的冷藏冷冻装置，当在储物容器的背壁上开设通气口，并将本体部固定于储物容器的后侧，且在本体部的端部连接向前弯折的弯折部时，由于可以通过螺接使弯折部与储物间室的侧壁固定连接，因此，基于上述结构，一方面可使气路总成的定位机构稳固地装配于储物间室内，以固定气调管路与通气口之间的接合部位，另一方面可使本体部固定在远离储物间室背壁的任意位置，使得本体部与储物间室的背壁之间预留出足够的空间以布置管路。

本发明实施例提供了一种冷藏冷冻装置10。图1是根据本发明一个实施例的冷藏冷冻装置10的示意性结构图。图2是根据本发明一个实施例的冷藏冷冻装置10的示意性内部结构图。冷藏冷冻装置10一般性地可包括箱体100、储物容器600、气调管路440和气路总成。本发明实施例的冷藏冷冻装置10可以为冰箱，也可以为冷柜、冷冻柜或者冷藏柜等具备低温储存功能的制冷设备。
箱体100的内部限定出储物间室。例如，箱体100可以包括内胆，内胆的内侧可以限定出上述储物间室。
储物容器600设置于储物间室内，且其内部限定出储物空间。储物容器600的壁上开设有连通储物空间的通气口610。例如，通气口610可以为开设于储物容器600的容器壁上的开口或开孔。储物容器600可以设置为一个或多个，例如两个。
气调管路440连通通气口610，并用于输送气体，使得储物空间与其外部环境进行气体交换。储物空间的外部环境可以指位于箱体100内部且位于储物空间之外的其他空间，例如风道盖板与内胆后壁之间的送风风道，发泡层，或者压机仓等；当储物空间为设置于储物间室内的储物容器600的内部空间时，储物空间的外部环境可以指形成于储物容器600外部的储物间室的内部空间。在另一些示例中，储物空间的外部环境也可以指箱体100的外部空间。
图3是图2所示的冷藏冷冻装置10的内部结构的示意性分解图。图4是图3中A处的局部放大图。气路总成包括定位机构850，定位机构850固定于储物容器600外部，且其具有供气调管路440与通气口610之间的接合部位装配其上以实现固定的固定部。
通过设置气路总成，并利用气路总成的定位机构850固定气调管路440与储物容器600的通气口610之间的接合部位，可以减少或避免气调管路440与通气口610之间的接合部位出现松动，这有利于提高气调管路440与储物容器600的通气口610之间的气路连接的稳定性，减少或避免因接合部位松动而漏气。
气调管路440与储物容器600的通气口610之间可以采用任意合适的方式进行接合，以实现气路连通。在一个示例中，气调管路440可以直接与通气口610相连接，此时，气调管路440与通气口610相连接的端部区段作为气调管路440与通气口610之间的接合部位。在另一个示例中，气调管路440与通气口610之间可以设置有连接结构，使得气调管路440间接地与通气口610相连接，此时，气调管路440与通气口610之间的连接结构可以作为气调管路440与通气口610之间的接合部位。
利用定位机构850固定气调管路440与通气口610之间的接合部位，即便储物容器600在用户取放物品的过程中偏离原始位置，或者出现晃动，也不会牵连气调管路440随之移动，并且当储物容器600归位时，可以重新与气调管路440建立气 路连接，因此，基于本实施例的方案，储物容器600无需固定不动地设置于储物间室内，气调管路440与通气口610之间的气路连接并不会制约储物容器600的移动，这提高了储物容器600的使用便利性。
在一些可选的实施例中，气路总成还包括管状连接件820，其第一端连通通气口610，其第二端连通气调管路440，并作为气调管路440与通气口610之间的接合部位。固定部限定出供管状连接件820插入其中以实现固定装配的中空筒状通道。
通过设置管状连接件820，并使管状连接件820的一端连通通气口610，另一端连通气调管路440，利用管状连接件820作为气调管路440与通气口610之间的接合部位，巧妙地连通气调管路440与通气口610，气调管路440的端口与通气口610之间并不需要直接地密封结合，这有利于简化冷藏冷冻装置10的储物空间与气调管路440之间的连通方式。
在一些可选的实施例中，定位机构850包括本体部851和盖体部852。其中，本体部851固定于储物间室内，且限定出向下凹陷并呈弧状的下凹弧形板；下凹弧形板作为中空筒状通道的下部通道壁。
盖体部852限定出向上凹陷并呈弧状的上凹弧形板，作为中空筒状通道的上部通道壁。上部通道壁和下部通道壁共同形成固定部。
本体部851和盖体部852可以分离独立设置，并非一体成型。利用本体部851和盖体部852共同限定出中空筒状通道，以供布置管状连接件820，由于本体部851和盖体部852可以分离独立设置，因此，在装配管状连接件820时，可以先将管状连接件820放置在本体部851的下凹弧形板上，然后再将盖体部852固定在本体部851上，这样一来，可使管状连接件820稳固地装配于中空筒状通道内。并且当需要拆卸管状连接件820时，分离本体部851和盖体部852即可，拆卸过程简便。
盖体部852可拆卸地装配于本体部851的上方。盖体部852还限定出位于上部通道壁两侧的第一螺纹孔。本体部851相应形成有位于下部通道壁两侧并与第一螺纹孔一一相对的第二螺纹孔，以通过螺接实现可拆卸地装配。
在一个示例中，通气口610位于储物容器600的背壁上。例如，本体部851可以与储物容器600的背壁贴靠设置。
定位机构850还包括弯折部854，弯折部854自本体部851的端部向前或向后弯折形成，且与储物间室的侧壁贴靠设置。弯折部854开设有第三螺纹孔，以通过螺接将弯折部854固定装配至储物间室的侧壁。
当在储物容器600的背壁上开设通气口610，并将本体部851固定于储物容器600的后侧，且在本体部851的端部连接向前弯折的弯折部854时，由于可以通过螺接使弯折部851与储物间室的侧壁固定连接，因此，基于上述结构，一方面可使气路总成的定位机构850稳固地装配于储物间室内，以固定气调管路440与通气口610之间的接合部位，另一方面可使本体部851固定在远离储物间室背壁的任意位置，使得本体部851与储物间室的背壁之间预留出足够的空间以布置管路。
通气口610为中空柱状，且其自储物容器600的壁向外隆起并至少部分地伸入 中空筒状通道内。管状连接件820的第一端821限定出供通气口610嵌套其中的中空筒状接口。
当通气口610为中空柱状并至少部分地伸入中空筒状通道内且嵌套于管状连接件820的第一端821所限定出的中空筒状通道之内时，沿远离管状连接件820的方向移动储物容器600，可使通气口610脱出管状连接件820的第一端821所限定出的中空筒状通道，沿靠近管状连接件820的方向移动储物容器600，可使通气口610重新嵌套于管状连接件820的第一端821所限定出的中空筒状通道之内，因此，基于上述结构，可使储物容器600与气调管路440之间以可拆卸的方式实现气路连接。
在一些可选的实施例中，气路总成还包括气路转接件810。图5是图3所示的冷藏冷冻装置10的气路转接件810的示意性结构图。图6是图5所示的冷藏冷冻装置10的气路转接件810的示意性透视图。
气路转接件810具有连通气调管路440的第一接口811以及连通管状连接件820的第二端的第二接口812，且第二接口812与第一接口811之间连接有气流通道813，使得气调管路440间接地连通通气口610。气流通道813相对于水平面倾斜设置。
储物空间的温度一般较低。由于气路转接件810经由管状连接件820直接连接至储物容器600的通气口610，且与储物空间距离较近，因此，当储物空间的温度较低时，气路转接件810的温度也相应较低。
通过将气路转接件810的气流通道813相对于水平面倾斜设置，可使气流通道813与水平面之间的夹角形成锐角或直角，当流经气路转接件810的气体含有水分且储物空间的温度较低时，气体所携带的水分不易在气流通道813内部滞留，这有利于减少或避免气流通道813因产生霜露而堵塞，使储物空间与其外部环境之间实现可持续性地气体交换，进而使储物空间能够长期维持低温保鲜气氛。
第一接口811和第二接口812分别为自气路转接件810的外表面向外隆起形成的中空柱状接口。
第一接口811和第二接口812的内部分别限定出连通气流通道813并且相对于水平面倾斜设置的中空通道。即，第一接口811的中空通道和第二接口812的中空通道也分别倾斜设置。
采用上述结构，由于每个接口的中空通道均与气流通道813连通，这相当于延长了气路转接件810的倾斜区段的路径，可以进一步地降低气路转接件810发生气路堵塞的风险，使气调管路440与通气口610之间保持畅通连接。
在一个示例中，管状连接件820的第二端822限定出供第二接口812嵌套其中的中空筒状接口，气调管路440连通通气口610的一端限定出供第一接口811嵌套其中的中空筒状接口，使得气调管路440间接地连通通气口610。
在一些可选的实施例中，气路转接件810的气流通道813包括第一通道区段813a和第二通道区段813b。其中，第一通道区段813a连通第一接口811内部的中空通道。第二通道区段813b连通第一通道区段813a，且连通第二接口812内部的中空通道。
第二通道区段813b的倾斜程度与第一通道区段813a的倾斜程度设置为不同。 换言之，第二通道区段813b与水平面之间的夹角与第一通道区段813a与水平面之间的夹角不同，这会导致气体所携带的液体在流经第一通道区段813a和第二通道区段813b时的流速产生不同。
通过在气路转接件810内布置两个倾斜程度不同的通道区段，一方面可以简化每个通道区段与对应接口之间的连接方式，另一方面由于气体在流经第一通道区段813a和第二通道区段813b时的流速不同，因此，本实施例的上述方案可以进一步地降低气流通道813发生气路堵塞的风险。
在一些可选的实施例中，第一通道区段813a与水平面之间的夹角大于第二通道区段813b与水平面之间的夹角。
采用上述方案，当气调管路440向储物空间输送气体时，即便气体所携带的液体可能会在第一通道区段813a内和第二通道区段813b内凝结，由于气体所携带的液体会率先在第一通道区段813a率内凝结，液珠的流速较大，这些液珠进入第二通道区段813b时会冲刷第二通道区段813b的表面，裹挟着第二通道区段813b内凝结的液珠继续向前高速流动，从而有效降低气路转接件810发生气路堵塞的风险。
在一些可选的实施例中，第一接口811形成于气路转接件810的上部区段，且第一接口811内部的中空通道朝向远离气路转接件810外表面的方向倾斜向上设置。第一通道区段813a的中心轴线与第一接口811内部的中空通道的中心轴线同轴。也就是说，第一接口811内部的中空通道的倾斜程度与第一通道区段813a的倾斜程度相同。
第二接口812形成于气路转接件810的侧部区段，且位于第二接口812的下方。第二接口812内部的中空通道朝向远离气路转接件810外表面的方向倾斜向下设置。第二通道区段813b的中心轴线与第二接口812内部的中空通道的中心轴线同轴。也即，第二接口812内部的中空通道的倾斜程度与第二通道区段813b的倾斜程度相同。
基于上述结构，气调管路440可以连接至气路转接件810的上部，管状连接件可以连接至气路转接件810的侧部。
在一个示例中，气调管路440的端口可以嵌套于第一接口811的中空通道内，管状连接件可以嵌套于第二接口812的中空通道内。
在一个示例中，管状连接件820由弹性材料制成。由于由弹性材料制成的管状连接件820可以与嵌套其中的接口紧密地贴合，因此，采用管状连接件820连通第二接口812与通气口610，能使第二接口812与通气口610之间气密性地接合。
在一些可选的实施例中，冷藏冷冻装置10还包括氧气处理装置300，设置于箱体100内，且其具有壳体320和电极对，壳体320的内部限定出用于盛装电解液的电化学反应仓，电极对设置于电化学反应仓且用于通过电化学反应将外部氧气转移至电化学反应仓。
图7是根据本发明一个实施例的冷藏冷冻装置10的氧气处理装置300的示意性结构图。图8是图7所示的冷藏冷冻装置10的氧气处理装置300的示意性分解图。
电极对可以包括阴极板330和阳极板340。电化学反应仓为阴极板330和阳极板 340进行电化学反应的场所，其内可以盛装碱性电解液，例如1mol/L的NaOH，其浓度可以根据实际需要进行调整。
壳体320具有侧向开口321。例如壳体320可以呈扁平的长方体形状。侧向开口321可以设置在壳体320的任意面上，例如顶面、底面或者侧面。在一个示例中，侧向开口321可以设置在壳体320的面积最大的面上。
阴极板330设置于侧向开口321处以与壳体320共同限定出用于盛装电解液的电化学反应仓，并用于通过电化学反应消耗氧气。空气中的氧气可以在阴极板330处发生还原反应，即：O2+2H2O+4e-→4OH-。
阳极板340与阴极板330相互间隔地设置于电化学反应仓内，并用于通过电化学反应向阴极板330提供反应物并生成氧气。阴极板330产生的OH-可以在阳极板340处发生氧化反应，并生成氧气，即：4OH-→O2+2H2O+4e-。
以上关于阴极板330和阳极板340的电化学反应的举例仅仅是示意性的，在了解上述实施例的基础上，本领域技术人员应当易于变换电化学反应的类型，或者针对适用于其他电化学反应类型的氧气处理装置300的结构进行拓展，这些变换和拓展均应落入本发明的保护范围。
壳体320上开设有连通电化学反应仓的排气孔323，用于排出电化学反应仓的氧气。气调管路440远离通气口610的一端(例如，气调管路440的第二端)用于连通排气孔323。气调管路440的第二端可以直接或间接地连通排气孔323。气调管路440连通通气口610的一端可以作为气调管路440的第一端，气调管路440的第一端可以直接或间接地连通气路转接件810的第一接口811。
在一些可选的实施例中，壳体320开设有连通电化学反应仓的补液口322。冷藏冷冻装置10还包括储液模块500，其设置于箱体100内，且其具有盒体510，盒体510的内部限定出用于储液的储液空间，储液空间连通补液口322，以向电化学反应仓补充电解液。储液空间所盛装的液体可以为水，或者也可以为电解液，其浓度可以低于电化学反应仓所盛装的电解液。
盒体510上开设有进气口512和出气口513。进气口512和出气口513可以开设于盒体510的顶壁上。其中，进气口512连通排气孔323，以允许排气孔323排出的氧气通入储液空间以过滤可溶性杂质，例如氧气所携带的电解液。出气口513用于允许过滤后的氧气向外排出，且直接地连通气调管路440远离通气口610的一端，使气调管路440间接地连通排气孔323。
采用上述结构，气调管路440可以向储物空间输送洁净的氧气。
在一个示例中，冷藏冷冻装置10可以包括内胆120和内胆150。以上实施例中，储物间室可以为内胆150的内部空间。内胆150可以限定出变温间室152或者冷冻间室152。为便于区分，上述储物空间可以命名为第一储物空间。内胆120限定出另一储物间室，例如冷藏间室，该储物间室内可以限定出另一储物空间122，为便于区分，该储物空间可以命名为第二储物空间。氧气处理装置300的阴极板与储物空间122气流连通，从而通过电化学反应降低储物空间的氧气含量。
在另一个示例中，氧气处理装置300可以设置于发泡层内。图9是根据本发明一个实施例的冷藏冷冻装置的示意性结构图，图10是图9所示的冷藏冷冻装置的示意性内部结构图，为便于示意各个部件的结构以及连接关系，图中隐去了发泡层。此时，冷藏冷冻装置10可以进一步地包括预埋于发泡层的换气管路200。换气管路200可包括进气管路210和回气管路220。
进气管路210用于将储物空间122的气体导引至阴极板330，回气管路220用于将流经阴极板330的气体导引回储物空间122，以降低储物空间122的氧气含量。例如，内胆120的胆壁上开设有连通进气管路210的第一端的第一换气口和连通回气管路220的第一端的第二换气口。每个换气口分别为形成于内胆120胆壁上的开口。进气管路210的第二端以及回气管路220的第二端可以分别连通阴极板330的两端，具体地，进气管路210的第二端可以连通阴极板330的上风侧，回气管路220的第二端可以连通阴极板330的下风侧，使得流出进气管路210的气体可以在流经阴极板330之后流入回气管路220。
采用上述结构，利用进气管路210与回气管路220连通储物空间122与氧气处理装置300，储物空间122内的氧气含量较高的气体可以经进气管路210流动至阴极板330处，使阴极板330利用其中的氧气作为反应物进行电化学反应，形成氧气含量较低的低氧气体，这些低氧气体可以经回气管路220返回至储物空间122，从而起到降低储物空间122氧气含量的作用。
氧气处理装置300可以设置于发泡层的任意部位，例如可以设置于内胆120的背部，或者可以设置于内胆120的顶部、底部以及侧部。对于法式冰箱或者T型冰箱而言，在一个示例中，氧气处理装置300可以设置于上部内胆120与下部内胆120之间的间隙中。
在一些可选的实施例中，发泡层背对内胆120的一侧开设有与发泡层的外部环境相通以供装配氧气处理装置300的装配凹槽。
在发泡层成型之后，氧气处理装置300可以装配至装配凹槽内，从而设置于发泡层内。装配凹槽可以在发泡层成型过程中预留出来。装配凹槽沿发泡层的厚度方向朝向靠近内胆120的方向凹陷，且与内胆120之间形成间隙。换言之，装配凹槽并未贯穿发泡层，这使得装配至装配凹槽的氧气处理装置300不会紧贴内胆120。也即，内胆120与氧气处理装置300之间形成有一定厚度的隔热保温材料。
采用上述结构，通过在发泡层背对内胆120的一侧开设连通发泡层的外部环境的装配凹槽，并使装配凹槽与内胆120之间形成间隙，氧气处理装置300可以在发泡层成型之后再安装至装配凹槽，这有利于简化氧气处理装置300的拆装难度。并且由于氧气处理装置300并不会紧贴内胆120，因此本实施例的方案能够减少或避免冷藏冷冻装置10的低温环境影响电化学反应的正常进行。
氧气处理装置300可以固定于装配凹槽内，固定方式包括但不限于螺接、卡接、铆接、焊接以及粘接。
在一些可选的实施例中，箱体100还包括箱壳170，其罩设于发泡层的外侧，以 与内胆120夹持发泡层。箱壳170具有背板，装配凹槽形成于内胆120的背壁与箱壳170的背板之间。也就是说，本实施例的氧气处理装置300设置于内胆120背部的发泡层内。箱壳170的背板可以封闭装配凹槽的开口，以使外形美观。
在一个示例中，箱壳170的背板可以开设有正对装配凹槽的安装口，在装配过程中，无需拆卸箱壳170的背板，可以直接通过安装口将氧气处理装置300固定至装配凹槽内。在一个进一步的示例中，安装口处可以设置有盖板，用于遮蔽安装口，以使外形美观。在另一个示例中，可以先将氧气处理装置300固定至装配凹槽内，然后再将箱壳170的背板覆盖在发泡层的背部。
采用上述结构，氧气处理装置300无需预装于发泡层内，避免发泡过程对氧气处理装置300的结构和性能产生不利影响，并且氧气处理装置300的装配过程可以在冷藏冷冻装置10的背部执行，具备装配过程简单等优点。
在又一个示例中，箱体100内还限定出用于安装压缩机的压缩机室。氧气处理装置300可以设置于压缩机室内。例如，压缩机室的底部设置有用于固定压缩机的支撑板，氧气处理装置300可以直接或间接地设置于支撑板上。
在一个示例中，盒体510设置于发泡层内。通过将储液模块500的盒体510设置于发泡层内，并使盒体510的储液空间与氧气处理装置300液路相通，以利用盒体510所储存的液体向氧气处理装置300补充电解液，由于盒体510并未占据储物空间122，因此冷藏冷冻装置10能够在不影响容积率的情况下，利用储液模块500向氧气处理装置300补充电解液，使氧气处理装置300可持续性地调节储物空间122的氧气含量。
储液模块500的盒体510可以设置于发泡层的任意部位，例如可以设置于内胆150的侧部，或者可以设置于内胆150的顶部、底部以及背部。对于法式冰箱或者T型冰箱而言，在一个示例中，储液模块500的盒体510可以设置于上部内胆150与下部内胆150之间的间隙中。
在一些可选的实施例中，箱体100还具有箱壳，发泡层形成于箱壳和内胆150之间。箱壳罩设于发泡层的外侧，以与内胆150夹持发泡层。在一个示例中，冷藏冷冻装置可以包括冷藏内胆、变温内胆和冷冻内胆。在一个进一步的示例中，盒体可以设置在冷藏内胆外侧的发泡层内。
图11是是根据本发明一个实施例的冷藏冷冻装置10的内胆120的示意性结构图。内胆120开设有开口状的交互窗口124，发泡层具有与交互窗口124相通以供装配储液模块500的安装凹槽。在发泡层成型之后，储液模块500可以装配至安装凹槽内，从而设置于发泡层内。安装凹槽可以在发泡层成型过程中预留出来。安装凹槽沿发泡层的厚度方向朝向背离交互窗口124的方向凹陷，且与箱壳之间形成间隙。换言之，安装凹槽并未贯穿发泡层，这使得装配至安装凹槽的储液模块500不会紧贴箱壳。也即，箱壳与氧气处理装置300之间形成有一定厚度的隔热保温材料。
采用上述结构，储液模块500无需预装于发泡层内，避免发泡过程对储液模块500的结构和性能产生不利影响，并且储液模块500的装配过程可以在储物空间122 内执行，具备装配过程简单等优点。
通过在内胆120上开设交互窗口124，并在发泡层中设置与交互窗口124相通的安装凹槽，且使安装凹槽与箱壳之间形成间隙，储液模块500可以在发泡层成型之后再安装至安装凹槽，这有利于简化储液模块500的拆装难度。并且由于安装凹槽并未贯穿发泡层，因此本实施例的方案能够减少或避免因在发泡层内安装储液模块500而导致冷藏冷冻装置10的保温性能明显降低。
储液模块500可以固定于安装凹槽内，固定方式包括但不限于螺接、卡接、铆接、焊接以及粘接。
在一些可选的实施例中，盒体510开设有连通储液空间的注液口514，且注液口514通过交互窗口124显露出来，从而允许外部液体注入储液空间。图12是图10所示的冷藏冷冻装置的储液模块的示意性结构图。图13是图12所示的冷藏冷冻装置的储液模块的示意性透视图。例如，注液口514设置于盒体510面朝储物空间122的侧壁上，以通过交互窗口124显露出来。
通过在内胆150上开设交互窗口124，并使盒体510的注液口514经交互窗口124连通储物空间122，可利用交互窗口124作为用户向储液空间补液的操作窗口。由于交互窗口124可将注液口514显露出来，当储液空间的储液量不足时，外部液体可以经注液口514注入储液空间，因此，本实施例的上述方案可简化储液模块500的补液方式，使储液模块500可持续性地向氧气处理装置300补充电解液。
盒体510上设置有盖体550，盖体550可往复运动地设置在注液口514处，以打开或封闭注液口514。盖体550打开注液口514时，允许注液口514显露出来。通过在盒体510上设置盖体550，并利用盖体550打开或封闭注液口514，可使注液口514仅在接收外部液体时呈开放状态，从而可减少或避免异物进入储液空间，使储液空间所储存的液体保持洁净。
盖体550可以为按压式弹盖，其受压可转动地弹起，以至少部分地经由交互窗口124伸入储物空间122内，从而打开注液口514。
在一个示例中，盖体550的底部可以通过转轴连接至盒体510，并与盒体510可枢转地连接。当盖体550封闭注液口514时，其外表面与盒体510的外表面共面，此时盖体550的顶部可以通过卡接结构连接至盒体510；当需要打开注液口514时，可以按压盖体550的顶部，使盖体550的顶部与盒体510脱离，此时盖体550可以绕转轴转动，并且至少部分地伸入储物空间122，从而打开注液口514。
在了解本公开实施例的基础上，本领域技术人员应当易于获知按压式弹盖与盒体510之间的装配结构，本公开不再赘述。
在一些可选的实施例中，盒体510的至少一部分由透明材料制成，以形成用于显露盒体510的储液量的可视区域516。透明材料可以为聚甲基丙烯酸甲酯、聚碳酸酯、聚对苯二甲酸乙二醇脂或者聚丙烯等。
本实施例的可视区域516通过交互窗口124显露出来。可视区域516沿纵向延伸设置，并位于注液口514的下方。例如，可视区域516也设置于盒体510面朝储 物空间122的侧壁上，以便通过交互窗口124显露出来。
通过在盒体510上设置可视区域516，并使可视区域516与交互窗口124相对，可利用交互窗口124作为用户观察储液空间液位的观察窗口。由于交互窗口124可将可视区域516显露出来，用户可以十分方便地观察储液空间的储液量，因此，本实施例的上述方案可使用户获得直观的交互体验。当储液空间的储液量不足时，用户可以及时地采取补液措施。
在一个示例中，交互窗口124可以位于内胆150的侧壁上，安装凹槽相应设置于内胆150的侧壁与箱壳的侧壁之间。
由于内胆150的侧壁不易被储物空间122所储存的物品所遮挡，且与用户的可活动区域距离较近，因此，在内胆150的侧壁上设置交互窗口124，并使储液模块500嵌入箱体100侧部的发泡层内，可以在一定程度上降低用户与储液模块500之间的交互难度，用户无需挪动储物空间122所储存的物品便可以快捷地获取储液模块500的储液量信息，并且可以在储液模块500的储液量不足时及时执行补液操作。
在一些可选的实施例中，储液模块500可以进一步地包括液位传感器，设置于储液空间内，并用于检测储液空间的液位。在液位传感器检测到储液空间的液位低于设定值时，冷藏冷冻装置10可以发出报警信号，例如可以通过无线传输技术将报警信号输送给用户，以提醒用户及时补液。
在一些进一步的示例中，盒体510具有与内胆150的侧壁相平齐且封闭交互窗口124的第一侧壁以及与第一侧壁相对并且隐藏于安装凹槽内部的第二侧壁。注液口514位于第一侧壁上。交互窗口124的开口面积与盒体510的第一侧壁的表面积可以大致相同，使得盒体510的第一侧壁恰好封闭交互窗口124且使第一侧壁的外表面与内胆150侧壁的内表面连接成完整的平面，以使外形美观。
注液口514可以设置于第一侧壁的上部区段。可视区域516也可以设置于第一侧壁上，例如可以设置于第一侧壁的中部区段或者下部区段。
盒体510可以大致呈扁平的长方体形状。盒体510开设有连通储液空间的出液口511。盒体510还具有连接于第一侧壁和第二侧壁之间且沿竖直方向相对设置的顶壁和底壁。底壁上开设有出液口511，出液口511连通补液口322，以向电化学反应仓补充电解液。
在一些可选的实施例中，盒体510还具有连接于第一侧壁和第二侧壁之间且沿水平方向相对设置的第三侧壁和第四侧壁。第三侧壁和/或第四侧壁的外表面连接有固定件517，固定件517具有用于与螺钉配合以将盒体510固定于安装凹槽的螺孔。
冷藏冷冻装置10还包括预埋于发泡层内的补液管路420，补液管路420的第一端连通氧气处理装置300的补液口322，补液管路420的第二端连通储液模块500的出液口511，以将自出液口511流出储液空间的液体导引至补液口322，从而向电化学反应仓补液。出液口511高于补液口322，如此一来，储液空间内的液体可以在重力作用下自动流入电化学反应仓，而无需借助动力装置。
当然，在另一些示例中，出液口511也可以变换为低于补液口322或与补液口 322相平。此时，可以在补液管路420上安装泵，以在泵的作用下驱使储液空间内的液体流入电化学反应仓；或者可以利用虹吸原理，使储液空间内的液体流入电化学反应仓。
在一些进一步的示例中，补液管路420上可以设置有单向阀，用于允许来自出液口的液体单向通过，保证流经补液管路420的液体的单向流动。
冷藏冷冻装置10还包括预埋于发泡层内的过滤管路430，过滤管路430的第一端连通氧气处理装置300的排气孔323，过滤管路430的第二端连通盒体510的进气口512，以将自排气孔323流出的氧气导引至出气口513，从而进入储液空间进行过滤。
储液模块500还可以进一步地包括滤气管540和出气管。其中，滤气管540从进气口512插入储液空间，并延伸至储液空间的底部区段，以将待过滤的氧气导引至储液空间，使得氧气中的可溶性杂质溶解于储液空间。出气管从出气口513插入盒体510内，并延伸至储液空间的上部区段，且位于储液空间所储存的液体上方，以将过滤后的氧气经其导引出。
采用上述方案，待过滤氧气可以在滤气管540的导引下到达储液空间，并且流经储液空间所储存的液体，使得氧气中的可溶性杂质溶解于储液空间，完成气体的净化。净化后的气体可以在出气管的导引下流入指定空间，从而起到调节空间氧气含量的作用。
在一个可选的实施例中，储液模块500还包括气阻机构530，设置于储液空间内，且将储液空间分隔出气路阻断的滤气区和非滤气区。其中，滤气区用于使流入进气口512的气体流经其中以实现过滤。非滤气区用于接收来自外部液体。
滤气区和非滤气区可以沿横向并列设置，气阻机构530阻断滤气区和非滤气区之间的一部分液路，使滤气区和非滤气区在气路阻断的情况下保持液路相通。例如，气阻机构530为位于滤气区与非滤气区之间且自盒体510的顶壁下表面向下延伸并与盒体510的底壁上表面之间形成间隙的隔板状结构。滤气区位于气阻机构530的横向一侧，非滤气区则位于气阻机构530的横向另一侧。进气口512和出气口513可以分别设置于滤气区所在区域的顶壁上。注液口514则可以设置于非滤气区所在区域的顶壁上。
采用上述结构，通过在储液空间内设置气阻机构530，并利用气阻机构530将储液空间分隔出气路阻断的滤气区和非滤气区，可实现仅在滤气区内执行净化气体的功能。由于滤气区仅为储液空间的一个子空间，且与储液空间的其他区域之间的气路阻断，通入进气口512的气体仅能在滤气区内流动，而不会自由扩散至非滤气区而导致无法快速排放，因此本实施例的储液模块500具备较高的净化气体释放率。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
