发明内容
本发明的一个目的旨在克服现有技术中的至少一个缺陷，提供一种冰箱及其电解除氧装置。
本发明一个进一步的目的是要简化了电解除氧装置的结构，降低了安装、维护的难度和成本。
本发明另一个进一步的目的是要提高电解除氧装置的可靠性。
本发明另一个更进一步的目的是收集多余电解液，避免浪费。
特别地，本发明提供了一种电解除氧装置，用于通过电化学反应分离流经其上的空气中的氧气，包括：封装壳，其内具有间隔设置的电解腔和用于盛装电解质溶剂的补液腔，电解腔远离补液腔的壁面具有开口；阴极复合板，设置于电解腔，并位于开口处，配置成允许流经其上的空气透过并进入电解腔，以通过电化学反应消耗空气中的氧气；阳极板，设置于电解腔，配置成通过电化学反应向阴极复合板提供反应物，且生成氧气；电解质模块，设置于电解腔，位于阴极复合板与阳极板之间，其内吸附有电解液，用于导电，其包括第一吸附体，第一吸附体具有主体板和连接于主体板与补液腔的连接件，连接件配置成吸收补液腔内的电解质溶剂并传导至主体板，以维持电解质模块的饱和度。
可选地，电解质模块还包括两个第二吸附体，两个第二吸附体均设置于电解腔，分别贴附于主体板的两面，并分别与阴极复合板和阳极板相接触， 以吸收主体板内的电解液，从而电性连接阴极复合板与阳极板。
可选地，电解质模块的底部与电解腔的底壁之间形成有预设空间，以便收集电解质模块上流出的电解液；且第一吸附体还包括形成于主体板底部的吸收部，吸收部伸入预设空间内并吸收电解液，以维持电解质模块的饱和度。
可选地，电解腔底壁的两侧具有凸台，电解质模块的底部两端分别搭设于两个凸台上，以在其中部下方形成预设空间。
可选地，电解腔和补液腔均向上敞开；且电解除氧装置还包括：盖体，设置于封装壳上，以封盖电解腔和补液腔。
可选地，盖体具有用于排出氧气的排气口；和/或盖体具有用于向电解腔注入电解液的第一注液口。
可选地，封装壳具有用于向补液腔注入电解质溶剂的第二注液口。
可选地，阴极复合板还包括自内而外依次设置的催化层、第一防水透气层、导电层和第二防水透气层。
可选地，第一吸附体为无纺布压合板；且/或第二吸附体为聚乙烯醇海绵。
特别地，本发明还提供了一种冰箱，包括上述任一项的电解除氧装置。
本发明的电解除氧装置，由于第一吸附体的主体板设置于电解腔，第一吸附体的连接件连接主体件和补液腔，第一吸附体具备一定吸水能力，因此在第一吸附体达到饱和状态前，不断从补液腔吸收电解液，直到电解质模块达到饱和度后停止，工作中电解质模块中的电解液不断被消耗，那么其会自发地从补液腔的电解液吸取加以补充，也即电解质模块可实现自动补液，无需设置复杂的补液系统，简化了电解除氧装置的结构，降低了安装、维护的难度和成本。
进一步地，本发明的电解除氧装置，阴极复合板作为电解腔的一个壁面，大量的液态电解液被盛装于补液腔内，电解质模块内最多吸附有维持使其具备导电功能的少量电解液，即便阴极复合板被破裂也不会导致大量的电解液泄漏，因此可取消用于收集泄漏电解液的储废罐，进一步简化了电解除氧装置的结构，并提高了电解除氧装置的可靠性。
进一步地，本发明的电解除氧装置，电解质模块的底部与电解腔的底壁之间形成有预设空间，以便收集电解质模块上流出的电解液，并且第一吸附体的吸收部可伸入预设空间内并吸收电解液，以利用收集的电解液维持电解质模块的饱和度，不仅可以充分利用收集的电解液，避免浪费，而且还可防 止多余电解液长期残留在电解腔的底部，挥发变质。

参见图1，图1是根据本发明一个实施例的冰箱1的示意图。本发明提供一种冰箱1，其一般性地可以包括箱体10和门体20。
箱体10可以包括外壳和多个内胆，外壳位于整体冰箱1的最外侧，以保护整个冰箱1。多个内胆被外壳包裹，并且与外壳之间的空间中填充有保温材料(形成发泡层)，以降低内胆向外散热。每个内胆可以限定出向前敞开的储物空间，并且储物空间可以被配置成冷藏室、冷冻室、变温室等等，具体的储物空间的数量和功能可以根据预先的需求进行配置。
门体20可动地设置于内胆的前方，以开闭内胆的储物空间，例如门体20可以通过铰接的方式设置箱体10前部的一侧，通过枢转的方式开闭储物空间。
该冰箱还可包括抽屉组件30，抽屉组件30还可包括抽屉本体，抽屉本体可抽拉地设置于储物空间内，以便用户拿取物品。
在一些实施例中，该冰箱1还可包括电解除氧装置40，该电解除氧装置40可设置于内胆或者抽屉组件30上，还可通过连接配件设置在箱体10的外部，通过电解反应分离流经其上的空气中的氧气，并将氮气留在内胆的储物空间或抽屉本体内，实现对食物的保鲜储存。
例如，该电解除氧装置40可设置于内胆的后壁、侧壁、顶壁、底壁等，也可设置于抽屉本体的后壁、侧壁、底壁等。总之，本领域技术人员在知晓本实施例的技术方案后可根据实际情况设置电解除氧装置40，在此不一一列举。
参见图2至图5，图2是根据本发明一个实施例的电解除氧装置40的示意图，图3是根据本发明一个实施例的电解除氧装置40的分解图，图4是根据本发明一个实施例的电解除氧装置40的纵向截面图，图5是根据本发明一个实施例的电解除氧装置40中第一吸附体410的示意图。进一步地，该电解除氧装置40还可包括封装壳100、阴极复合板200、阳极板300和电解质模块400。
封装壳100内具有间隔设置的电解腔110和用于盛装电解质溶剂的补液腔130，电解腔110远离补液腔130的壁面具有开口140。
阴极复合板200设置于电解腔110，并位于开口140处，阴极复合板200可允许流经其上的空气透过并进入电解腔110，以通过电化学反应消耗空气中的氧气。
阳极板300设置于电解腔110，阳极板300可通过电化学反应向阴极复合板200提供反应物(例如电子)，且生成氧气。
电解质模块400设置于电解腔110，位于阴极复合板200与阳极板300之间，其内吸附有电解液，用于导电，电解质模块400还可包括第一吸附体410，第一吸附体410具有主体板412和连接于主体板412与补液腔130的连接件414，连接件414配置成吸收补液腔130内的电解质溶剂并传导至主体板412，以维持电解质模块400的饱和度。
在本实施例中，封装壳100在电解腔110远离补液腔130一侧壁面打开形成开口140，阴极复合板200设置在开口140，也即阴极复合板200可作为电解腔110的一个侧壁，冰箱1储物空间内的空气可流经阴极复合板200，阴极复合板200具有防水透气功能，可允许空气进入电解腔110内，并且阴极复合板200可加载外部电源的负极，空气中的氧气可在阴极复合板200处 发生还原反应，生成负离子，即：O 2+2H 2O+4e -→4OH -。
阳极板300可与阴极复合板200间隔地设置于电解腔110内，并加载外部电源的正极，在阴极复合板200处生成的负离子在电场的作用下流向阳极板300，并在阳极板300上发生氧化反应，生成氧气，即：4OH -→O 2+2H 2O+4e -。
电解质模块400设置于电解腔110，位于阴极复合板200与阳极板300之间，可用于将阴极复合板200与阳极板300导通，实现离子交换，例如可电场作用下使阴极复合板200处生产的负离子流向阳极板300等。
电解液可由电解质和电解质溶剂组成，其中电解质可为NaOH等，电解质溶剂可为纯水，最终可配置成0.1～8mol/LNaOH电解质溶液(具体可根据实际情况调整浓度)。
在使用之前，电解质模块400可预先吸附足够的电解液，电解质模块400的第一吸附体410具有主体板412和连接件414，主体板412与连接板可一体成型，并且两者均具备一定的吸液能力，补液腔130内预先盛装电解质溶剂连接件414浸入补液腔130的电解质溶剂内，这样可以实现补液腔130的电解质溶剂可通过连接件414源源不断地供向主体板412，使主体板412处于饱和状态，进而使电解质模块400具备电性连接阴极复合板200和阳极板300的功能。
如背景技术部分所述，现有技术出现的电解除氧装置需要设置补液系统(补液开关、液位计等)，为本身使用空间紧张的电解除氧装置增加额外负担，结构复杂，不利于安装、维护等。
为了克服现有技术的缺陷，本实施例的电解除氧装置40的第一吸附体410具备一定吸水能力，第一吸附体410的连接件414将主体板412与补液腔130的电解质溶剂连接起来，在第一吸附体410达到饱和状态前，不断从补液腔130吸收电解质溶剂，直到电解质模块400达到饱和度后停止，工作中电解质模块400中的电解质溶剂不断被消耗，那么其会自发地从补液腔130的电解质溶剂吸取加以补充。也就是说，本实施例的电解质模块400可实现自动补液，无需设置复杂的补液系统，简化了电解除氧装置40的结构，降低了安装、维护的难度和成本。
此外，阴极复合板200作为电解腔110的一个壁面，阴极复合板200一旦被外部物体刺破可能出现电解液泄漏的风险，而在本实施例中，大量的液态电解质溶剂被盛装于补液腔130内，电解质模块400内最多吸附有维持使 其具备导电功能的少量电解液，即便阴极复合板200被破裂也不会导致大量的电解液泄漏，因此可取消用于收集泄漏电解液的储废罐，进一步简化了电解除氧装置40的结构，并提高了电解除氧装置40的可靠性。
参见图4，在一些实施例中，电解质模块400还可包括两个第二吸附体420，两个第二吸附体420均设置于电解腔110，分别贴附于主体板412的两面，并分别与阴极复合板200和阳极板300相接触，以吸收主体板412内的电解液，从而电性连接阴极复合板200与阳极板300。
也即，本实施例的电解腔110内结构为在封装壳100的开口140向内部方向上依次设置阴极复合板200、第二吸附体420、主体板412、第二吸附体420和阳极板300，并且相邻两个部件紧贴，这样主体板412吸附到的电解液可扩散至位于其两面的第二吸附体420，而两个第二吸附体420分别贴靠在阴极复合板200和阳极板300，这样阴极复合板200与阳极板300被电性导通，可实现离子交换。
在一些具体的实施例中，第一吸附体410还可配置成硬质板，例如采用无纺布压合板、纤维板等，以为电解质模块400提供强度支撑，第二吸附体420还可配置成软质弹性吸水板，例如聚乙烯醇海绵等，这样不仅可吸收较多的电解液，提高电解质模块400的导电性，而且可紧密地与阴极复合板200或阳极板300贴合，防止断路。
参见图5和图6，图6是根据本发明一个实施例的电解除氧装置40中封装壳100的纵向截面图。在一些实施例中，电解质模块400的底部与电解腔110的底壁之间形成有预设空间160，以便收集电解质模块400上流出的电解液，第一吸附体410还包括形成于主体板412底部的吸收部416，吸收部416伸入预设空间160内并吸收电解液，以维持电解质模块400的饱和度。
具体地，电解腔110底壁的两侧具有凸台120，电解质模块400的底部两端分别搭设于两个凸台120上，以在其下方中部形成预设空间160，两个凸台120同时还可起到支撑电解质模块400的作用，以使其稳固地处于电解腔110内。当然，本领域技术人员还可采用其他固定手段(紧固件等)实现电解质模块400悬空地设置于电解腔110内，且底部形成预设空间160，在此不一一列举。
在组装电解除氧装置40之前，可预先为电解质模块400吸附足够的电解液，若电解质模块400处于过饱和状态，电解液在重力作用下流入电解质 模块400底部的预设空间160内，实现收集多余电解液。
随着电化学反应不断进行，电解质模块400的饱和度下降，第一吸附体410的吸收部416伸入预设空间160内，将收集的多余电解液供给至主体板412，进而维持电解质模块400的饱和度，这样不仅可以充分利用收集的电解液，避免浪费，而且还可防止多余电解液长期残留在电解腔110的底部，挥发变质。
参见图3和图4，在一些实施例中，电解腔110和补液腔130均向上敞开，并且电解除氧装置40还可包括盖体500，盖体500设置于封装壳100上，以封盖电解腔110和补液腔130。
参见图4，由于第一吸附体410的主体板412位于电解腔110，连接件414连接在主体板412与补液腔130之间，因此连接件414需跨越电解腔110与补液腔130之间的隔板150，当盖体500封盖电解腔110和补液腔130的同时，还可将连接件414压紧在隔板150上，以实现固定第一吸附体410。
盖体500可设置用于排出氧气的排气口510，排气口510还可靠近阳极板300设置，以便使得阳极板300产生的氧气更顺畅地排出，进而促使电化学反应向正向进行，提升除氧效率。
盖体500还可设置用于向电解腔110注入电解液的第一注液口512，以便预先为电解质模块400吸附足够的电解液。
封装壳100还可设置用于向补液腔130注入电解质溶剂的第二注液口(图中未示出)，以便定期向补液腔130补充电解质溶剂。由于电解除氧装置40在后续的工作中，只有电解液中的电解质溶剂被消耗，因此，在使用一段时候仅需通过第二注液口向补液腔130加注电解质溶剂即可。
第一注液口512和第二注液口上还可分别配置注液塞520，以便封堵第一注液口512和第二注液口。
参见图3，在一些实施例中，阴极复合板200可以由从内向外依次设置的催化层210、第一防水透气层220、导电层230和第二防水透气层240，所述“由从内向外”可以理解成由封装壳100的内部向开口140的方向。催化层210可以采用贵金属或稀有金属催化剂，例如金属铂、金属金、金属银、金属锰或金属铷等。第一防水透气层220和第二防水透气层240可以为防水透气膜，以使得电解液无法从储液腔渗出，而空气可以透过第一防水透气层220和第二防水透气层240进入储液腔。导电层230可以制作成耐腐金属集 流网，例如金属镍、金属钛等，以使其不仅具备较佳的导电性、防腐性和支撑强度。
阳极板300可采用耐蚀性和还原性强的材料制成，例如金属泡沫镍、镍网等。
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。
