氧气处理装置以及具有其的冷藏冷冻装置 技术领域
本发明涉及气调保鲜技术，特别是涉及氧气处理装置以及具有其的冷藏冷冻装置。
背景技术
气调保鲜技术是通过调节环境气体成分来延长食品贮藏寿命的技术。具备气调保鲜功能的冷藏冷冻装置广受青睐。在众多的气体成分中，氧气备受关注。氧气处理装置能够对周围气体中的氧气进行处理，从而起到调节氧气含量的作用。
然而，发明人认识到，现有技术中的部分氧气处理装置，例如，一些利用电化学反应来处理氧气的氧气处理装置，需使阴极膜直接接触空间的氧气才能进行电化学反应，这极大地限制了氧气处理装置的搭载环境，氧气处理装置的装配对场景的结构依赖度很高，并且氧气处理装置对空气中的氧分子捕捉仅依靠分子扩散原理进行，工作效率较低，且空间的氧气含量变化不均匀。

在本发明实施例的描述中，参考术语“一个实施例”、“一些实施例”、“一些示例”、“一个示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
本发明实施例首先提供了一种氧气处理装置10。参看图1至图3，氧气处理装置10一般性地可包括壳体200和氧气处理组件300。
其中，壳体200上形成有用于连通外部管路的进气接口231和出气接口221，且其内部限定出连通进气接口231和出气接口221的气流通道280。由于壳体200上形成有进气接口231和出气接口221，因此，气流通道280可以通过管路连通待调节的空间，使得待调节空间内的气体可以自进气接口231流入气流通道280，并流经氧气处理组件300，以在氧气处理组件300的作用下形成贫氧气体或富氧气体。
氧气处理组件300设置于气流通道280内，并用于处理自进气接口231流入气流通道280的气体中的氧气，以产生贫氧气体或富氧气体。贫氧气体或富氧气体经出气接口221送出，从而调节外部空间的氧气含量。此处的外部空间可以指待调节的空间，例如冷藏冷冻装置的储物空间。也就是说，进气接口231和出气接口221可以分别通过外部管路连通同一空间。当然，在另一个示例中，进气接口231和出气接口221可以分别通过外部管路连通不同空间。
通过在壳体200上设置用于连通外部管路的进气接口231和出气接口221，并将氧气处理组件300设置在连通进气接口231和出气接口221的气流通道280内，来自外部空间的气体可经进气接口231流入气流通道280内，并接受氧气处理组件300的处理，从而形成贫氧气体或富氧气体，最终从出气接口221送出。由于外部空间的气体可经由管路进入进气接口231，因此，采用本实施例的方案，氧气处理装置10可以设置在任意位置，例如，设置在远离待调节空间的任意位置，这可降低氧气处理装置10的装配对场景结构依 赖度，提高氧气处理装置10在冷藏冷冻装置20中的装配灵活性，且扩大氧气处理装置10的应用范围。
氧气处理组件300可以消耗氧气或者生成氧气，从而起到调节流经气流通道280的气体中的氧气含量的作用，达到处理氧气的目的。氧气处理组件300可以采用任意方式来消耗氧气或者生成氧气，例如，可以采用电化学反应方式、吸附方式、膜过滤方式、溶解方式或者任意其他化学方式。
在一些可选的实施例中，氧气处理装置10还可以进一步地包括进气管路和出气管路。进气管路连通进气接口231，并作为进气接口231的外部管路。出气管路连通出气接口221，并作为出气接口221的外部管路。进气管路远离进气接口231的一端可以延伸至待调节的空间。出气管路远离出气接口221的一端可以延伸至待调节的空间。待调节空间内的气体经进气管路流入进气接口231，并流入气流通道280，然后经出气接口221流出气流通道280，并经出气管路流回待调节空间，进气接口231和出气接口221可以分别直接或间接地连通各自的外部管路。
在一个示例中，进气接口231和出气接口221可以分别为形成于壳体200上的开口或开孔。在一些可选的实施例中，进气接口231为形成于壳体200上并向外***的中空柱状接口；且/或出气接口221为形成于壳体200上并向外***的中空柱状接口。
当进气接口231为形成于壳体200上并向外***的中空柱状接口，且/或出气接口221为形成于壳体200上并向外***的中空柱状接口时，进气接口231和/或出气接口221可以通过插接或者嵌套的方式连通外部管路，这可以降低氧气处理装置10与外部管路之间连接的操作难度。
参看图4和图5，在一些可选的实施例中，进气接口231与出气接口221形成于壳体200的两个不同的壁上，这样可以适当地延长进气接口231与出气接口221之间的距离，使气流通道280具有较长的气流路径，使得气体流经气流通道280时的流动时间增加，从而与氧气处理组件300充分地接触。在一个示例中，进气接口231形成于壳体200的底壁210或者一个侧壁上，出气接口221形成于壳体200的顶壁220或者另一个侧壁上。进气接口231和出气接口221的位置可以互换。
在一个进一步的实施例中，进气接口231与出气接口221沿纵向和横向错位布置。例如，在一个示例中，进气接口231形成于壳体200的底部区段，出气接口221形成于壳体200的顶部区段；进一步地进气接口231可以位于壳体200的横向一侧，进一步地出气接口221可以位于壳体200的横向另一侧。在一个进一步的示例中，壳体200大致呈空心柱状，例如空心棱柱或者空心圆柱，进气接口231设置于壳体200的侧壁上，并位于壳体200的底部，出气接口221设置于壳体200的顶壁220上，并远离设置有进气接口231的壳体200的侧壁，以与进气接口231斜向相对。
通过将进气接口231和出气接口221设置在壳体200的两个不同的壁上，或进一步地使进气接口231与出气接口221沿纵向和横向错位布置，可以延长流经气流通道280的气体流动路径，使流经气流通道280的气体与氧气处理组件300充分接触，从而使得送出出气接口221的贫氧气体的氧气含量处于较低水平， 或使得送出出气接口221的富氧气体的氧气含量处于较高水平。
参看图6和图7，在一些可选的实施例中，氧气处理装置10还包括气流促动装置，设置于气流通道280内，且其具有吸风口411和出风口412。其中，吸风口411与进气接口231气流连通，出风口412与出气接口221相对。且气流促动装置用于促使形成自进气接口231流入气流通道280并流向出气接口221的气流。
当在气流通道280内设置气流促动装置，并使气流促动装置的吸风口411与进气接口231气流连通，且使气流促动装置的出风口412与出气接口221相对时，外部空间的气体可以在气流促动装置的促动下，自进气接口231流入气流通道280并流向出气接口221，形成主动式的高速的气流循环结构，改变了仅依靠分子扩散原理捕捉氧气的方式，有助于提升单位时间内流经气流通道280的气体流量，从而提高氧气处理装置10的工作效率。
在一个示例中，气流促动装置为离心风机。当然，在另一些示例中，气流促动装置也可以替换为任意其他风机，例如轴流风机等。
在一些可选的实施例中，气流通道280具有连接进气接口231并且过流截面渐扩的第一区段281以及连接气流促动装置的吸风口411并且过流截面渐缩的第二区段282。气体在流经第一区段281时，在气体流动方向上，垂直于气流的流线簇的断面面积(即，过流截面的面积)逐渐扩大。气体在流经第二区段282时，在气体流动方向上，垂直于气流的流线簇的断面面积(即，过流截面的面积)逐渐缩小。
通过在气流通道280内设置连接进气接口231并且过流截面渐扩的第一区段281以及连接气流促动装置400的吸风口411并且过流截面渐缩的第二区段282，可以分别利用第一区段281和第二区段282对流经气流通道280的气体进行导流，从而减少或避免扰流。并且在第一区段281的作用下，流入进气接口231的气体可以减速流动，以延长流动时间，从而与氧气处理组件300充分接触；在第二区段282的作用下，气体可以加速流动并以较高的速度流出出气接口221，以提高待调节空间的气调效率。
在一个示例中，第一区段281和第二区段282可以直接地相连。氧气处理组件300可以设置于第一区段281内或者第二区段282内，当然也可以设置于第一区段281和第二区段282的相接部位，或者同时设置于第一区段281和第二区段282内。
在另一个示例中，气流通道280还具有连接于第一区段281和第二区段282之间的第三区段283。如图4和图5所示，第一区段281和第二区段282分别位于第三区段283的两侧。图5中虚线示出了第一区段281与第三区段283之间的分界线以及第二区段282与第三区段283之间的分界线。
氧气处理组件300设置于第三区段283内。在气体流动方向上，第三区段283的过流截面的面积(即，垂直于气流的流线簇的断面面积)可以保持不变。这样一来，流经第三区段283的气体的流速无明显变化，可使氧气处理组件300的各个部位均匀地与流经的气体接触，从而均匀地产生贫氧气体或富氧气体。
如图6和图7所示，在一些可选的实施例中，氧气处理装置10还包括定位机构500，其固定于气流通 道280内，并与气流促动装置固定连接，以将气流促动装置固定在气流通道280内。
当需要将气流促动装置安装至气流通道280时，可以先将气流促动装置装配于定位机构500上，然后再将定位机构500装配于气流通道280内，例如固定于壳体200的内壁上。采用定位机构500使气流促动装置间接地固定于气流通道280，可避免直接在较为狭小的气流通道280内执行气流促动装置与壳体200的连接操作。
在一些进一步的实施例中，气流促动装置包括蜗壳410以及设置于蜗壳410内的风轮420。吸风口411和出风口412分别形成于蜗壳410上。
定位机构500限定出供蜗壳410装配其中的安装槽510，还限定出连通安装槽510并与出风口412贯通的第一开口520以及连通安装槽510并与吸风口411贯通的第二开口530。第一开口520可以正对蜗壳410的吸风口411，第二开口530可以正对蜗壳410的出风口412。蜗壳410可以通过螺接的方式固定于安装槽510内。
通过将气流促动装置装配于定位机构500的安装槽510内，且利用第一开口520和第二开口530连通安装槽510，可以提高气流促动装置与定位机构500之间的装配稳定性，且减少或避免定位机构500堵塞气流促动装置的吸风口411和出风口412。
在一些可选的实施例中，定位机构500还限定出自安装槽510的至少一部分开口边缘向外延伸形成的外凸卡爪540。壳体200的内壁相应地限定出供外凸卡爪540***其中以实现卡接的卡槽241。
采用上述方案，通过在气流通道280内固定定位机构500，并使定位机构500与气流促动装置固定连接，以将气流促动装置固定在气流通道280内，当采用卡爪与卡槽241的配合结构将定位机构500固定在壳体200的内壁上时，可简化氧气处理装置10的气流促动装置的装配方式。
在一些可选的实施例中，外凸卡爪540可以自安装槽510的至少一部分开口边缘沿径向向外延伸形成，例如可以自安装槽510的横向两端以及底端向外延伸形成。
在一个示例中，定位机构500还限定出自安装槽510的开口边缘的顶端向外延伸形成的翻边550。翻边550上开设有第一螺孔551，壳体200的内壁相应形成有与第一螺孔551相对的第二螺孔242，以通过螺接使翻边550与壳体200的内壁固定连接。
在另一个示例中，定位机构500可以同时限定出外凸卡爪540与翻边550，从而同时利用卡爪与卡槽241的配合结构以及螺接结构将定位机构500固定在壳体200的内壁上，这有利于进一步提高气流促动装置在气流通道280内的装配稳定性。
参看图8，在一些可选的实施例中，氧气处理组件300具有用于处理流经气流通道280的气体中的氧气以产生贫氧气体或富氧气体的处理部320。处理部320的外表面沿流经第三区段283的气流的流线簇的延伸方向伸展。处理部320可以为板状电极，例如阴极。
也即，处理部320的外表面的伸展方向平行于流经第三区段283的气流的流线簇的延伸方向，这样一来，流经第三区段283的气体可以按照时序均匀地与处理部320的外表面各处接触，从而延长单位时间内处理部320与待处理气流的接触时长。
在一些进一步的实施例中，处理部320为阴极，其用于通过电化学反应消耗流经气流通道280的气体中的氧气，以产生贫氧气体。空气中的氧气可以在处理部320处发生还原反应，即：O2+2H2O+4e-→4OH-。
参看图9和图10，氧气处理组件300还包括电解仓310和配合部330。
其中，电解仓310具有侧向开口315。例如电解仓310可以呈扁平的长方体形状，侧向开口315可以设置于电解仓310的面积较大的侧壁上。处理部320设置于侧向开口315处以与电解仓310共同限定出用于盛装电解液的电解腔。电解腔为处理部320和配合部330进行电化学反应的场所，其内可以盛装碱性电解液，例如1～8mol/L的NaOH，其浓度可以根据实际需要进行调整。
配合部330，其作为阳极，设置于电解腔内，并用于通过电化学反应向处理部320提供反应物，且生成氧气。配合部330与处理部320可以相互间隔地设置于电解腔内。处理部320产生的OH-可以在配合部330处发生氧化反应，并生成氧气，即：4OH-→O2+2H2O+4e-。在一个示例中，配合部330可以为板状电极。在另一些示例中，配合部330当然也可以为变换为柱状或者弧状等任意其他合适的形状。
以上关于处理部320和配合部330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10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。
在一些可选的实施例中，氧气处理组件300还包括排气仓340，其设置于电解仓310的上方，并且开设有排气孔。排气仓340连通电解腔，并用于收集配合部330生成的氧气，且经排气孔排出。也就是说，排气仓340一方面连通电解腔，另一方面连通外部环境，以将自排气孔排出的氧气排至外部环境。
经排气仓340收集并排出的氧气可以直接排放。当然在另一个示例中，经排气仓340收集并排出的氧气也可以输送至冷藏冷冻装置20的高氧保鲜空间，以营造高氧保鲜气氛，提升冷藏冷冻装置20的保鲜性能。
采用上述结构，既可以利用氧气处理装置10消耗冷藏冷冻装置20的低氧保鲜空间的氧气，也可以利用氧气处理装置10提升冷藏冷冻装置20的高氧保鲜空间的氧气，可实现氧气处理装置10的功能复用。
在一些可选的实施例中，排气仓340与电解仓310一体成型。如此设置，可以省略排气仓340与电解仓310之间的装配结构，且保证排气仓340与电解腔之间的连接结构的气密性。电解仓310和排气仓340之间形成有气液连通口，使电解仓310和排气仓340实现互通。
在一些可选的实施例中，壳体200上还开设有排氧口222。氧气处理装置10还包括排氧管350，其一端连通排气孔，另一端自排氧口222伸出至壳体200外部，用于将经排气孔排出的氧气排至壳体200外部。
在另一些可选的实施例中，氧气处理装置10还可以省略排氧管350，排气孔可以为形成于排气仓340上并向外***的中空柱状接口，排气孔可以经排氧口222伸出至壳体200外部，以将流经的氧气排至壳体200外部。
在一些可选的实施例中，壳体200上还开设有注液口,223。且氧气处理装置10还包括补液管360，其一端连通电解腔，另一端自注液口223伸出至壳体200外部，用于将外部液体导引至电解腔。
在一些可选的实施例中，壳体200具有底壁210和顶壁220以及分别自底壁210向上延伸至顶壁220并且相对设置的第一侧壁230和第二侧壁240。
出气接口221形成于壳体200的顶壁220上，例如可以设置于壳体200的横向一侧。进气接口231形成于壳体200的第一侧壁230上，例如第一侧壁230可以形成于壳体200的横向另一侧，进气接口231可以设置于第一侧壁230的底部中央。气流促动装置固定于壳体200的第二侧壁240上，并且位于出气接口221的下方。
采用上述结构，在气流促动装置的作用下，流经气流通道280的气体能够沿倾斜向上的方向流动，延长了流经气流通道280的气体流动路径。
壳体200还具有第三侧壁250和第四侧壁260、第一导流面271和第二导流面272以及第三导流面273和第四导流面274。
其中，第三侧壁250和第四侧壁260分别自底壁210向上延伸至顶壁220并与第一侧壁230和第二侧壁240共同围出具有顶部开口的筒体。在一个示例中，第一侧壁230大致平行于第二侧壁240，第三侧壁250大致平行于第四侧壁260。
第一导流面271和第二导流面272分别自第一侧壁230的内表面延伸至第三侧壁250的内表面以及第四侧壁260的内表面，且与第一侧壁230的内表面之间形成钝角，以限定出第一区段281。第一导流面271可以自第一侧壁230靠近第三侧壁250的端部区段的内表面延伸至第三侧壁250靠近第一侧壁230的端部区段的内表面。第二导流面272可以自第一侧壁230靠近第四侧壁260的端部区段的内表面延伸至第四侧壁260靠近第一侧壁230的端部区段的内表面。
第三导流面273和第四导流面274分别自第二侧壁240的内表面延伸至第三侧壁250的内表面以及第四侧壁260的内表面，且与第二侧壁240的内表面之间形成钝角，以限定出第二区段282。第三导流面273可以自第二侧壁240靠近第三侧壁250的端部区段的内表面延伸至第三侧壁250靠近第二侧壁240的端部区段的内表面。第四导流面274可以自第二侧壁240靠近第四侧壁260的端部区段的内表面延伸至第四侧壁260靠近第二侧壁240的端部区段的内表面。
在一个示例中，壳体200的顶壁220、底壁210、第一侧壁230、第二侧壁240、第三侧壁250、第四侧壁260、第一导流面271、第二导流面272、第三导流面273以及第四导流面274均可以通过一体成型工艺 制造出来。采用上述结构，由于壳体200可以采用一体成型工艺批量化生产，因此，一方面可以简化整个氧气处理装置10的装配工序，另一方面可以保证产品的一致性。
在一个示例中，壳体200的顶壁220可拆卸地设置。并且壳体200顶壁220的边缘可以与顶部开口的边缘固定连接，以实现密封。连接方式包括但不限于螺接、粘接或者卡接等。排氧口222和注液口223可以分别设置于壳体200的顶壁220上。补液管360连通电解腔的一端可以连通排气仓340，从而间接地连通电解腔。
在另一个示例中，氧气处理装置10还包括液量调节仓700，其设置于电解仓310的一侧，且其内部限定出用于储存液体的储液空间。储液空间可通过液路连通管380连通电解腔，以向电解腔补充液体。补液管360连通电解腔的一端可以连通储液空间，从而间接地连通电解腔。
氧气处理组件300可以设置为一个或多个，例如两个，三个，四个或者更多个。液量调节仓700可以设置为至少一个，例如一个，两个，三个，四个或者更多个。
各个氧气处理组件300和液量调节仓700可以分离独立设置并沿水平并列排布且互通。“互通”是指液量调节仓700与任一氧气处理组件300均可以直接或间接地相通，以实现液体交换，从而使液位保持一致。当然，在一个示例中，当各个氧气处理组件300和液量调节仓700互通时，液量调节仓700与任一氧气处理组件300之间也可以实现气体交换。本实施例的液量调节仓700与各个氧气处理组件300沿水平方向层叠设置。
液量调节仓700具有连通外部液源的补液口342，以接收来自外部液源的液体并向至少一个氧气处理组件300提供。
液量调节仓700用于储液。本实施例的液量调节仓700并非用于装配电极对。来自外部液源的液体可经补液口342进入液量调节仓700。由于液量调节仓700与各个氧气处理组件300互通，因此，进入液量调节仓700的液体可以流入氧气处理组件300的电解仓310，以向电解仓310补充电解液。
采用上述方案，由于液量调节仓700与各个氧气处理组件300的电解仓310形成连通器，并可基于连通器原理达到液位一致，因此，采用本实施例的方案，有利于降低补液过程对电极对的冲击力，提高氧气处理装置10的结构稳定性。
在一个示例中，液量调节仓700为一个。当液量调节仓700设置为一个时，可减小整个氧气处理装置10的体积。在另一个示例中，液量调节仓700也可以设置为两个，三个或者更多个。此时可在一定程度上提高整个氧气处理装置10的储液量，减少补液频率。
氧气处理组件300可以为一个，当然也可以根据实际需要设置为多个，例如两个，三个或者更多个。如图2-4所示，图中示出了一个液量调节仓700和两个氧气处理组件300。当氧气处理组件300设置为多个时，可提高整个氧气处理装置10的氧气调节效率，使其快速营造合适的保鲜气氛。
电解仓310和排气仓340可以共同形成氧气反应仓。由于液量调节仓700和氧气反应仓分别用于储液，因此，可将液量调节仓700和氧气反应仓统称为储液仓。各个储液仓实现互通的方式可以根据实际需要进行设置。在一些可选的实施例中，每个储液仓分别开设有液路连通口312。氧气处理装置10还包括至少一个液路连通管380，一液路连通管380连通两个储液仓的液路连通口312，使各个储液仓液路连通。
例如，一个液路连通管380可以连通相邻两个储液仓的液路连通口312。此时，位于首端和末端的两个储液仓无需直接地连通。液路连通管380的数量比储液仓的数量少一个。采用本实施例的方案，液路连接结构简单，便于储液仓的增减。
在另一个示例中，相邻储液仓之间可以相互嵌入，或者相互插接，以实现内部空间的互相连通。
由于各个储液仓分离独立设置，当在储液仓上开设液路连通口312，并利用液路连通管380连通储液仓的液路连通口312以实现液路连通时，可根据实际需要十分方便地增减储液仓的数量，因此，采用本实施例的方案，可以灵活机动地调整氧气处理装置10的结构和工作效率，无需针对各个储液仓的内部结构进行适应性改造，并且整个装置具备较高的整合性和集成性。
在一个示例中，液路连通口312位于储液仓的底部区段。液路连通口312可以设置于储液仓的侧壁上。例如，液路连通口312可以设置在储液仓的侧壁下部。采用本实施例的方案，当液量调节仓700向电解仓310补液时，液体可以自电解仓310的底部缓缓地进入电解仓310内，不会对电极对产生冲刷作用，从而可降低补液过程对电极对造成损伤。
每个储液仓的液路连通口312可以设置为两个，以通过液路连通管380分别与相邻两个储液仓连接起来。位于首端和末端的两个储液仓各有一个液路连通口312处于“闲置状态”，未与相邻储液仓的液路连通口312连接，此时可采用密封塞391封闭处于“闲置”状态的液路连通口312，以防漏液。
在一些可选的实施例中，每一储液仓的顶部区段开设有气路连通口343。气路连通口343可以设置于储液仓的顶壁220上。当然，气路连通口343也可以设置在储液仓的侧壁上，并位于储液仓的侧壁上部。
氧气处理装置10还包括至少一个气路连通管370，一气路连通管370连通两个储液仓的气路连通口343，使储液仓气路连通。例如，一个气路连通管370可以连通相邻两个储液仓的气路连通口343。此时，位于首端和末端的两个储液仓无需直接地连通。气路连通管370的数量比储液仓的数量少一个。采用本实施例的方案，气路连接结构简单，便于储液仓的增减。
一个储液仓还开设有与气路连通口343气路连通并用于连通外部环境的通气口341。通气口341可以开设在任一个储液仓上。该通气口341连通所在储液仓的气路连通口343，且连通各个储液仓的外部环境，从而使各个储液仓与外部环境直接或间接地气路连通。
通过在储液仓的顶部区段开设气路连通口343，并利用气路连通管370使各个储液仓实现气路连通，且在一个储液仓开设与气路连通口343气路连通并用于连通外部环境的通气口341，可在各个储液仓内串联出 连通外部环境的气流空间，当液量调节仓700接收来自外部液源的液体时，在气流空间的作用下，有利于实现气液平衡，减少或避免补液过程产生气阻，保证补液过程顺畅进行。
采用上述方案，全部储液仓内的气体均可以通过通气口341排入外部环境。当在电解仓310内进行的电化学反应产生气体时，各个电解仓310内产生的气体均可以汇集至通气口341，并集中排出，这便于废气的集中处理和利用。通气口341可以设置于一个储液仓的顶壁220上。例如，通气口341可以设置于排气仓340的顶壁220上。在另一个示例中，当在一个储液仓开设一个通气口341时，还可以进一步地在另一储液仓开设另一通气口341，以提高排气速率。
在一些可选的实施例中，对于氧气反应仓而言，液路连通口312开设于电解仓310，气路连通口343开设于排气仓340，气路连通口343可以开设于排气仓340的顶壁上。例如，液路连通口312可以开设于电解仓310的侧壁下部。气路连通口343可以作为排气仓340的排气孔。通气口341开设于任一个氧气反应仓的排气仓，例如，通气口341可以位于该氧气反应仓的排气仓的顶壁上。
在一个示例中，液量调节仓700包括上仓体740和下仓体730。补液口342开设于液量调节仓700的上仓体740，例如可以开设于液量调节仓700的上仓体740的顶壁。气路连通口343也开设于液量调节仓700的上仓体740，例如可以开设于液量调节仓700的上仓体740的顶壁。
参看图11，其中，图11(a)采用虚线示意透视部位，图11(b)采用实线示意透视部位。氧气处理装置10还包括液位开关720，设置于液量调节仓700的下仓体730内，用于根据下仓体730内的液位移动，从而通断液量调节仓700的下仓体730与上仓体740之间的通路。
当液量调节仓700的液量减少时，液位开关720可以向下移动从而打开液量调节仓700的下仓体730与上仓体740之间的通路，此时来自外部液源的液体可以经上仓体740流入下仓体730，以提高液量调节仓700的液量。当液量调节仓700的液量增加时，液位开关720可以向上移动至初始位置从而使液量调节仓700的下仓体730与上仓体740之间的通路恢复至关断状态，此时来自外部液源的液体无法流入下仓体730。
当在液量调节仓700的上仓体740开设补液口342，并在液量调节仓700的下仓体730设置液位开关720时，在液位开关720的作用下，可使各个储液仓内的液位处于动态平衡状态，从而保证电化学反应的平稳进行。并且储液仓所储存的液体可始终处于下仓体730内，不会占据上仓体740所限定出的气流空间。
液位开关720可包括转动式浮子721、转动轴723和开关本体722。其中，转动轴723固定于下仓体730内。开关本体722与转动式浮子721固定连接，或与转动式浮子721为一体件。转动式浮子721可绕转动轴723可转动地设置于下仓体730内，并根据下仓体730内的液位上下浮动，从而带动开关本体722移动，进而通断液量调节仓700的下仓体730与上仓体740之间的通路。
液量调节仓700的上仓体740内设置有连通补液口342且与气路连通口343间隔设置的隔离仓710。隔离仓710的底部开设有出液口711，并通过出液口711连通液量调节仓700的下仓体730。隔离仓710与上 仓体740相连通且与气路连通口343间隔设置是指，流入上仓体740的液体仅能进入隔离仓710，并经隔离仓710的出液口711流入下仓体730，不会流向气路连通口343，且流向气路连通口343的气体不会流入隔离仓710。
液位开关720用于通过移动开闭出液口711，从而通断液量调节仓700的下仓体730与上仓体740之间的通路。例如，当液量调节仓700的下仓体730内的液量充足且无需补液时，液位开关720的开关本体722可恰好封闭出液口711。转动式浮子721在浮力变化的情况下通过带动开关本体722移动从而打开或封闭出液口711，从而通断液量调节仓700的下仓体730与上仓体740之间的通路。
出液口711可以贯穿于隔离仓710的底壁，并向下凸出设置。开关本体722可以具有与出液口711的底端开口相适配以封闭出液口711的密封塞391。
采用上述方案，当液位开关720关断液量调节仓700的下仓体730与上仓体740之间的通路时，流入上仓体740内的液体可以全部暂存于隔离仓710内，而不会溢流至上仓体740的其他部位，可使液量调节仓700的气流空间保持干燥、畅通。液位开关720可配置成使液量调节仓700的液位始终低于上仓体740。
在一些可选的实施例中，当氧气处理组件为多个时，多个氧气处理组件间隔排布，每个电解仓310可以开设有两个侧向开口315，每个侧向开口315处设置有一个阴极。也即，每个电解仓310装配有两个阴极以及一个共用的阳极。
采用上述方案，由于电解仓310并未相互遮挡，各个电解仓310均能与外部气体接触，因此，可以提高装配至电解仓310的阴极与外部气体的接触面积，从而提高电化学反应效率。侧向开口315可以设置在电解仓310的任意壁上。
在一些可选的实施例中，侧向开口315可以设置在垂直于多个氧气处理组件300的排布方向且面积最大的电解仓310的壁上。也即，电解仓310的面积最大的壁垂直于多个氧气处理组件300的排布方向，侧向开口315设置在电解仓310的面积最大的壁上。如此设置，可提高阴极的工作面积，从而进一步提高电化学反应效率。
在一些可选的实施例中，电解仓310为扁平形状。与传统的氧气处理装置相比，本发明实施例的氧气处理装置10在保持较高工作效率的情况下，体积明显降低。
各个储液仓可以相互连接，以实现集成式的装配，例如可以通过卡接结构、插接结构或者螺接结构等实现相互连接。
在一些可选的实施例中，氧气处理装置10还可以进一步地包括至少一个连接轴392。连接轴392可以设置为一个或多个，例如两个，三个，四个或者更多个。各个储液仓的壁设置有贯穿设置且同轴的至少一个轴孔311，轴孔311与储液仓的内部空间相互隔断，且供连接轴392***其中，从而实现连接。每个储液仓的轴孔311的数量与连接轴392的数量相同。一个连接轴392***多个储液仓的同轴的轴孔311内。当 连接轴392的数量和每个储液仓的轴孔311的数量分别为多个时，各个储液仓的轴孔311可以划分为多组，每组轴孔311同轴设置，相同的连接轴392贯穿多个储液仓的同组轴孔311。
在一个进一步的示例中，连接轴392为四个，且每一储液仓的壁设置有四个轴孔311。其中，两个轴孔311位于储液仓的顶部区段，另外两个轴孔311位于储液仓的底部区段。
采用上述方案，各个储液仓可以通过连接轴392装配为一体，装配方式简单，且相邻储液仓之间可形成气流间隙。
在一个示例中，壳体200的顶壁220连接有自顶壁220的边缘向下延伸从而限定出下部开口的折边。
折边的竖直长度可以根据实际需要进行调整，以适应不同的场景。折边的竖直长度大致等同于下部开口的深度。下部开口的边缘与第一侧壁、第二侧壁、第三侧壁以及第四侧壁共同围出的筒体的顶部开口的边缘相贴合，以实现密封。
如图12所示，当折边的竖直长度较小时，为避免因空间狭小而导致无法装配气路连通管370，可在壳体200的顶壁220上开设光孔，以供气路连通管370的至少一部分经其伸出至壳体200的外部。
本发明实施例还提供了一种冷藏冷冻装置20。本发明实施例的冷藏冷冻装置20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。结合图13，冷藏冷冻装置20包括箱体600和氧气处理装置10。箱体600的内部限定出储物空间610。氧气处理装置10可以采用以上任一实施例所示出的结构。
氧气处理装置10的出气接口221连通储物空间610，例如可以经由回气管路连通储物空间610。贫氧气体或富氧气体经出气接口221送出，从而调节储物空间610的氧气含量。
在一个示例中，储物空间610可以为低氧保鲜空间；氧气处理组件300用于通过电化学反应消耗流入气流通道280的气体中的氧气，以产生贫氧气体。此时，在一个进一步的示例中，箱体600内还可以进一步地限定出高氧保鲜空间。该高氧保鲜空间可以通过管路连通壳体200上的排氧口222，以接收来自排氧口222的氧气。
在另一个示例中，储物空间610可以为高氧保鲜空间。氧气处理组件300用于通过电化学反应生成氧气，并经排气孔排出。氧气处理组件300的排气孔可以连通气流通道280，并连通出气接口221，出气接口221可以通过管路连通高氧保鲜空间，以将电化学反应生成的氧气输送至高氧保鲜空间。
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。
