本发明的电解除氧系统及其控制方法以及冰箱，由于电解除氧系统可以根据电解除氧装置的电解液消耗量确定电解除氧装置的工作时长，并根据工作时长确定是否提示更换电解除氧装置的工作元件，因此，本发明的控制方法提供了一种电解除氧装置的状态监测手段，控制逻辑简单而巧妙，有利于降低状态监测难度。
进一步地，本发明的电解除氧系统及其控制方法以及冰箱，由于电解除氧装置的电解液消耗量能够准确地反映电解除氧装置的工作时长，因此，本发明的方案，能够间接地、准确地确定电解除氧装置实际发生电化学反应的时长，相对于根据电解除氧装置的累计安装时长判定是否达到老化状态的方案而言，具备明显提高的状态监测精度。
更进一步地，本发明的电解除氧系统及其控制方法以及冰箱，由于电解除氧系统的复位开关可在电解除氧装置断电的情况下切换至断路状态，此时即便用户人为地闭合电解除氧装置所在供电回路的开关元件，电解除氧装置所在的供电回路仍为断路，因此，本发明的方案，可以避免电解除氧装置在老化状态下进行除氧，这有利于提高电解除氧装置的运行可靠性。

具体实施方式
图1是根据本发明一个实施例的电解除氧系统2的控制方法的示意图。电解除氧系统2具有电解除氧装置100，其用于在电解电压的作用下通过电化学反应消耗氧气。电解除氧装置100的内部盛放电解液。电解除氧装置100的电化学元件浸于电解液，从而进行电化学反应，并消耗电解液。
电解除氧系统2的控制方法一般性地可包括如下步骤：
步骤S102，获取电解除氧装置100的电解液消耗量。电解液消耗量是指电解除氧装置100进行电化学反应时所消耗的电解液的量。本实施例的电解液消耗量可为体积值，其单位为升(L)。在一些实施例中，电解液消耗量也可为质量值，其单位为千克(kg)。
步骤S104，根据电解液消耗量计算电解除氧装置100的工作时长。电解除氧装置100的工作时长是指电解除氧装置100进行电化学反应的累计反应时长。
步骤S106，判断工作时长是否达到预设的时长阈值。其中，时长阈值用于衡量电解除氧装置100的寿命。时长阈值可以根据电解除氧装置100的某一关键部件(例如下述阴极板)的最佳使用周期进行设置。例如，时长阈值可以等于最佳使用周期，或者与最佳使用周期之间的差值处于预设范围内。
步骤S108，若是，则输出提示信号，以提示用户更换电解除氧装置100的工作元件，例如下述阴极板。例如，电解除氧系统2可进一步地设置有蜂鸣器，或者警示灯，通过控制蜂鸣器发出警报提示音，或者控制警示灯发出警报提示光，可完成提示信号的输出。发明人认识到，阴极板易于老化，因此，本实施例所提及的更换电解除氧装置100的工作元件可以指更换阴极板。在一些实施例中，也可以根据电解除氧装置100的其他工作元件的最佳使用周期确定时长阈值，从而判定是否输出提示信号，在此不做具体限定。
使用上述方法，由于电解除氧系统2可以根据电解除氧装置100的电解液消耗量确定电解除氧装置100的工作时长，并根据工作时长确定是否提示更换电解除氧装置100的工作元件，因此，本实施例提供了一种电解除氧装置100的状态监测手段，控制逻辑简单而巧妙，有利于降低状态监测难度。
由于电解除氧装置100的电解液消耗量能够准确地反映电解除氧装置100的工作时长，因此，本实施例的方案，能够间接地、准确地确定电解除氧装置100实际发生电化学反应的时长，相对于根据电解除氧装置100的累计安装时长判定是否达到老化状态的方案而言，具备明显提高的状态监测精度。
图2是根据本发明一个实施例的电解除氧系统2的示意性框图。除了电解除氧装置100外，电解除氧系统2进一步地可包括控制装置800，其具有处理器810和存储器820，存储器820内存储有机器可执行程序821，机器可执行程序821被处理器810执行时，用 于实现根据以下任一项的控制方法。
控制装置800的内部集成有电解除氧装置100的供电电源。供电电源与电解除氧装置100之间通过供电线700连接成供电回路，使得供电电源依靠供电回路向电解除氧装置100提供电解电压。通过对供电线700的通断状态进行控制，即可切断或恢复电解除氧装置100的电解电压。
控制装置800可以为主控芯片。其中存储器820内存储有机器可执行程序821，机器可执行程序821被处理器810执行时用于实现以下任一实施例的电解除氧系统2的控制方法。处理器810可以是一个中央处理单元(CPU)，或者为数字处理单元(DSP)等等。存储器820用于存储处理器810执行的程序。存储器820可以是能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何介质，但不限于此。存储器820也可以是各种存储器的组合。由于机器可执行程序821被处理器810执行时实现下述方法实施例的各个过程，且能达到相同的技术效果，为避免重复，这里不再赘述。
图3是根据本发明一个实施例的电解除氧系统2的示意性结构图。本实施例的电解除氧系统2进一步地可包括补液仓200，用于向电解除氧装置100补充电解液。此处的电解液应做广义理解，既可以指电解除氧装置100内的电解液，又可以指电化学反应过程实际消耗的电解液中的某些成分，例如水等。
例如，电解除氧装置100具有阳极板和阴极板，作为电化学元件。空气中的氧气可以在阴极板处发生还原反应，即：O 2+2H 2O+4e -→4OH -。阴极板产生的OH -可以在阳极板处可以发生氧化反应，并生成氧气，即：4OH -→O 2+2H 2O+4e -。整个电化学反应过程仅消耗水。随着电化学反应的进行，电解除氧装置100内原有的电解液中的水分不断减少。补液仓200的内部形成储液空间210，本实施例中，储液空间210内可以直接盛放水，以向电解除氧装置100补充反应物。
本实施例的电解除氧系统2同时集成有除氧功能和补液功能，能够利用自身的补液仓200向电解除氧装置100补液，有利于降低电解除氧装置100的补液难度，电解除氧装置100的补液过程更加安全、有效、及时、智能，可进一步保证电解除氧装置100的除氧效果。
将电解除氧装置100与补液仓200进行有机结合，形成电解除氧系统2，可解决除氧过程所存在的补液困难、安全风险高、废气污染、电解质流失等问题，在一定程度上可保证除氧过程连续进行，有利于促进电解除氧装置100在冰箱1领域的推广应用，提高冰箱1的保鲜性能。
上述步骤S102包括：获取补液仓200的液位变化值，根据液位变化值确定电解除氧装置100的电解液消耗量。由于补液仓200向电解除氧装置100补液，因此可使电解除氧装置100的液位处于“稳定值”，补液仓200的液位变化值直接反映电解除氧装置100的电解液消耗量。
在一些可选的实施例中，电解除氧装置100进一步地可包括反应容器(例如可为长方体形状)，阳极板和阴极板分别设置于反应容器内，或与反应容器的内部空间相通，从而浸于电解液。反应容器上开设有用于连通补液仓200的补液口116，以允许来自补液仓200的液体流入反应容器内。补液仓200上开设有供液口262，用于连通补液口116。即，供液口262与电解除氧装置100的补液口116相连通，以向电解除氧装置100补充 电解液。输液管300连接于供液口262与补液口116之间，以形成输液通道。
电解除氧系统2可以进一步地包括液位开关500，设置于反应容器内，且其具有开关本体520，并用于根据反应容器内的液位移动，从而开闭补液口116，以允许或制止补液仓200内的液体流经供液口262和补液口116进入反应容器内。也就是说，液位开关500用于控制补液口116的开闭。即，液位开关500作为输液通道的闸门，起到通断输液通道的作用。液位开关500的开关本体520根据反应容器的液位高低而进行移动，以此来封闭或打开补液口116，补液口116的开闭过程无需电控。
例如，补液口116可以设置于反应容器的顶盖上。供液口262高于补液口116。开关本体520可移动地设置于补液口116的下方，并且在反应容器内的液位升高的情况下通过上升至与补液口116的下周缘相抵压以封闭补液口116，且在反应容器内的液位降低的情况下通过下降偏离补液口116的下周缘从而打开补液口116。
也就是说，开关本体520可在反应容器内的液位升高的情况下上升并抵扣在补液口116的下周缘从而封闭补液口116，使得补液仓内的液体无法通过补液口116，还可在反应容器内的液位降低的情况下下降从而偏离并打开补液口116，使得补液仓内的液体可以依靠自身重力下流至反应容器内，以此实现对反应容器内的液位控制，使其趋向稳定。
使用上述方法，根据补液仓200的液位变化值间接地确定电解除氧装置100的电解液消耗量，既可保证确定过程的准确性，又可避免直接测定反应容器内的液位变化值，安全可靠。
在一些可选的实施例中，补液仓200内设置有液位传感器900。且获取补液仓200的液位变化值的步骤包括：获取液位传感器900的检测值，根据检测值确定液位变化值。液位传感器900与控制装置800数据连接，用于检测补液仓200内的液位变化值，并向控制装置800发送。
由于本实施例的补液仓200内盛放的液体为水，不具有腐蚀性，因此，通过在补液仓200内设置液位传感器900，以间接地检测电解除氧装置100的电解液消耗量，可以防止液位传感器900因受酸碱腐蚀而影响检测结果的准确性或者缩短寿命。此外，液位传感器900无需进行耐酸耐碱处理，因此还可降低整个系统的制造成本。在一些可选的实施例中，储液空间内可以盛放浓度较低的电解液，以弥补电解除氧装置100的排气过程所产生的电解质损失。电解液的浓度较低，因此，腐蚀性较小，或可忽略不计。
液位传感器900可以指静压液位计、液位变送器以及水位传感器中的任一种传感器，是一种测量液位的压力传感器。
在一些可选的实施例中，上述步骤S104包括：获取电解液消耗量与工作时长之间的对应关系，根据对应关系确定工作时长。例如，根据电解液消耗速率确定电解液消耗量与工作时长之间的对应关系。电解液消耗量与工作时长呈正比例关系，且二者之间的比值为电解液消耗速率。电解液消耗速率可由工程师进行预先计算并设定。液位传感器900可以每隔预设时间间隔检测一次电解液消耗量。
使用上述方法，可以在电解除氧装置100的使用过程中不断地监测电解除氧装置100的工作时长，有利于提高监测过程的可靠性，以便于及时发现电解除氧装置100的状态老化问题。
在一些可选的实施例中，补液仓200的容积具有预设的固定值。例如，补液仓200的容积V＝x╳y╳(1+z)，其中，x为电解除氧装置100的电解液消耗速率，其单位为L/h (升/小时)，y为电解除氧装置100的工作元件的最佳使用周期，其单位为h(小时)，z为常数。本实施例的液位传感器900可以设置于补液仓200的底部。当补液仓200内的液位下降至预设的警戒线位置时，液位传感器900发出触发信号并传送给电解除氧系统2的控制装置800，此时控制装置800将根据上述触发信号判定电解除氧装置100的工作时长是否达到时长阈值。液位传感器900的安装位置和警戒线的位置可以高于补液仓200的供液口262设置，图3中的虚线示出液位传感器900的安装高度和警戒线的位置。在一些实施例中，z为百分数，例如可以为1％～10％范围内的任意值，给与一定的余量z，用于表征补液仓200顶部和底部的部分空间。
使用上述方法，对补液仓200的容积进行预先设计，并根据补液仓200的容积进行注水之后，液位传感器900仅需要在补液仓200的液位下降至警戒线位置时向控制装置800发送一次触发信号，即可确定工作时长已达时长阈值，当补液仓200的液位没有下降至警戒线位置时则无需发送，这可以简化数据处理过程，使之简便而有效。
在电解除氧系统2投入使用之前，先对补液仓200注水，注水至指定位置后，随着电化学反应的不断进行，补液仓200内的水分被不断消耗，当补液仓200内的液位下降至警戒线时，意味着到电解除氧装置100的关键部件的使用时长已达最佳使用周期。指定位置可以指补液仓200的最高液位处。指定位置与警戒线位置之间的体积大小根据最佳使用周期内电解除氧装置100的电解液消耗量进行确定。在提示更换关键部件的同时，也意味着补液仓200需要重新加注，一举两得。
在一些可选的实施例中，在输出提示信号的同时，控制方法还包括：切断电解除氧装置100的电解电压，使其停止进行电化学反应。切断电解除氧装置100的电解电压是指切断电解除氧装置100与其供电电源之间的电路。通过切断电解除氧装置100所在的供电回路，可切断电解除氧装置100的电解电压。例如，供电回路上可以设置有开关元件，通过控制开关元件打开或闭合，可切断或接通电解除氧装置100的电解电压。
通过在发出提示信号的同时使电解除氧装置100自动地停止进行电化学反应，能够避免因部件老化而导致的耗电或者发生安全事故，有利于提高系统运行的可靠性。
在一些进一步的实施例中，电解除氧系统2还具有复位开关，设置于电解除氧装置100所在的供电回路上，并用于在电解除氧装置100的电解电压被切断的情况下切换至断路状态。例如，复位开关可以与电解除氧装置100串联设置于供电回路中。当复位开关为断路状态时，即便闭合开关元件，供电回路仍处于断路状态，电解除氧装置100无法通电启动。
复位开关可以设置于控制装置800内，仅能由专业的工程师才可操作，以将复位开关的状态调整为短路状态。例如，工程师在完成更换和检查上述关键部件、且对补液仓200进行再次注水之后，按下复位开关，可将复位开关调整为短路状态。如此设置，可以防止电解除氧装置100在未更换部件的情况下因用户人为地接通电解电压而通电启动，从而避免发生电能浪费或导致安全事故。
在切断电解除氧装置100的电解电压之后，控制方法还包括：检测复位开关的状态，且在复位开关恢复至短路状态时接通电解除氧装置100的电解电压，使其继续进行电化学反应。例如，在复位开关恢复至短路状态且冰箱1的储物空间101具有除氧需求时，可闭合开关元件，以接通电解除氧装置100的电解电压，使电解除氧装置100利用电化学反应消耗储物空间101的氧气。
在一些进一步的实施例中，在确定复位开关恢复至短路状态之后，控制方法还可以进一步地包括：检测补液仓200的液位，以确定补液仓200内是否已注水至指定位置，若是，则执行接通电解除氧装置100的电解电压的步骤，这可以保证电化学反应的顺利进行。在检测补液仓200液位的步骤中，根据液位传感器900的检测值可确定补液仓200的液位。
图4是根据本发明一个实施例的电解除氧系统2的控制流程图。电解除氧系统2的控制流程一般性地可包括如下步骤：
步骤S402，获取液位传感器900的检测值。
步骤S404，根据检测值确定液位变化值。
步骤S406，根据液位变化值确定电解除氧装置100的电解液消耗量。
步骤S408，获取电解液消耗量与工作时长之间的对应关系。
步骤S410，根据对应关系确定工作时长。
步骤S412，判断工作时长是否达到预设的时长阈值，若是，则执行步骤S414，若否，则执行步骤S402。
步骤S414，输出提示信号，以提示用户更换电解除氧装置100的工作元件。
步骤S416，切断电解除氧装置100的电解电压，使其停止进行电化学反应。
步骤S418，检测复位开关的状态。
步骤S420，在复位开关恢复至短路状态时接通电解除氧装置100的电解电压，使其继续进行电化学反应。
图5是根据本发明另一实施例的电解除氧系统2的控制流程图。本实施例的电解除氧系统2的控制流程一般性地可包括如下步骤：
步骤S502，获取液位传感器900的触发信号。在获取到触发信号的情况下，即确定电解除氧装置100的电解液消耗量达到预设消耗阈值，且通过获取与预设消耗阈值相对应的电解除氧装置的工作时长确定电解除氧装置的实际工作时长。
步骤S504，确定电解除氧装置100的工作时长达到预设的时长阈值。
步骤S506，输出提示信号，以提示用户更换电解除氧装置100的工作元件。
步骤S508，切断电解除氧装置100的电解电压，使其停止进行电化学反应。
步骤S510，检测复位开关的状态。
步骤S512，在复位开关恢复至短路状态时接通电解除氧装置100的电解电压，使其继续进行电化学反应。
图6是根据本发明一个实施例的冰箱1的示意性结构图。
冰箱1一般性地可包括如以上任一项实施例的电解除氧系统2，电解除氧装置100与冰箱1的储物空间101气流连通，用于通过电化学反应消耗储物空间101的氧气。冰箱1还可以进一步地包括箱体，其内部限定出上述储物空间101。电解除氧系统2可以设置于箱体内，从而提高冰箱1的结构一体性。
在一些实施例中，上述电解除氧系统2的控制装置800可以集成设置于冰箱1的主控板上，这有利于简化冰箱1整体的电控结构。
图7是根据本发明一个实施例的电解除氧系统2的液位开关500的示意性结构图。
参考图7，下面将对液位开关500的具体结构进行进一步介绍。液位开关500还包括浮子510，与开关本体520固定连接或与开关本体520为一体件，且可绕轴转动地设置， 用于在反应容器内通过绕轴转动实现上浮或下沉，从而带动开关本体520移动。也就是说，开关本体520由浮子510进行“驱动”，浮子510进行移动所需的动力由其在反应容器内所受的浮力决定。
例如，浮子510的一部分通过浸于液体，从而使浮子510受到液体的浮力。当反应容器的内部空间的液位发生变化时，浮子510所受的浮力也会发生变化，从而使得浮子510所受的浮力与重力的合力发生变化。例如，当反应容器内的液位降低时，浮子510所受的浮力会减小，若浮子510所受的浮力与重力的合力方向向下，则会导致浮子510向下运动。反之，则会导致浮子510向上运动。
本实施例的浮子510并非沿直线做升降运动，而是以绕轴转动的方式上升或下降，如此设计，仅需要使浮子510与某一固定轴进行可枢转地连接即可，无需安装尺寸精度较高的导向部件，具备结构精巧、装配过程简单、装置可靠性好的优点。
由于浮子510可绕轴转动地设置，运动轨迹清晰明确，这使得本实施例的浮子510和开关本体520易于沿清晰明确的运动轨迹移动，从而提高液位开关500的可靠性，减少或避免了因浮子510自由运动而带来密封不严等问题。
液位开关500还可以进一步地包括旋转轴530和连接件540。
其中，旋转轴530固定于反应容器。例如，旋转轴530可以固定于反应容器的内部空间，且与反应容器的容器内壁固定连接。
在一些可选的实施例中，旋转轴530还可以可拆卸地固定于反应容器，这可以根据实际需要调节旋转轴530的高度，从而调节开始启动补液的容器内的液位高度。
连接件540与浮子510固定连接或与浮子510为一体件，其上形成有轴孔，以供旋转轴530插入其中且可转动地配合从而实现可转动地连接。也就是说，连接件540将旋转轴530与浮子510装配成一个有机的整体，使得浮子510可绕旋转轴530转动。
通过在连接件540上开设轴孔，并使旋转轴530与轴孔可转动地配合，即可将浮子510可绕轴转动地装配至旋转轴530，结构精妙，工序简单。
开关本体520呈杆状。连接件540上还形成有安装口，以供开关本体520的一部分插入其中从而实现固定装配。也就是说，开关本体520的一部分通过与连接件540固定装配，从而间接地与浮子510实现固定连接。例如，上述开关本体520的一部分可与连接件540的安装口通过过盈配合的方式进行装配。
分别将旋转轴530与开关本体520装配至与浮子510固定连接或与浮子510为一体件的连接件540，从而形成液位开关500，结构整体性强。
图8是根据本发明一个实施例的电解除氧系统2的过滤机构400的示意性结构图。图9是图8所示的电解除氧系统2的过滤机构400的示意性分解图。
在一些实施例中，电解除氧系统2还包括过滤机构400，其具有壳体420和过滤部440。壳体420的内部空间421与储液空间210相连通，过滤部440设置于壳体420的内部空间421，并用于使来自排气口112的气体中的特定物质成分溶解于壳体420的内部空间421，以便进入储液空间210供回收使用。也就是说，从排气口112排出的气体可以在过滤部440的作用下实现过滤，以分离出特定物质成分，并使特定物质成分滞留在壳体420的内部空间421。壳体420内形成用于盛装液体的空间，例如可以盛装含有特定成分的电解液或者水等。反应容器所排出的气体中的特定物质成分可以溶解于壳体420的内部空间421是指溶解于反应容器所盛装的液体中。
由于过滤机构400可使电解除氧装置100排出的气体中的特定物质成分溶解于壳体420的内部空间421，从而使待排放气体得到过滤，这有利于降低电解除氧装置100所排放气体的腐蚀性，降低除氧过程对环境产生的不良影响。
此外，由于过滤机构400的壳体420与储液空间210相连通，溶解于壳体420内的特定物质成分可以进入储液空间210，因此，电解除氧装置100所排放的气体中的特定物质成分能够得到回收再利用，这有利于降低除氧过程的资源消耗。
上述特定物质成分为可溶于水的物质。在一些可选的实施例中，可根据待分离的特定物质成分的物理化学性质调整壳体420内和补液仓200内所存放的液体成分。
图10是根据本发明一个实施例的电解除氧系统2的补液仓200和过滤机构400的示意性结构图。图11是图10所示的电解除氧系统2的补液仓200和过滤机构400的示意性透视图。
对于壳体420与储液空间210之间的连通方式，在一些可选的实施例中，壳体420插入储液空间210，且壳体420的底部开设有用于连通储液空间210的出液孔，以允许壳体420内的液体回流至补液仓200内。例如，补液仓200可以大致呈长方体状，壳体420可以作为内套管插入补液仓200内。关于补液仓200和壳体420的形状举例，仅仅是示意性的，本领域技术人员应当易于拓展，此处不再一一枚举。
出液孔422可作为壳体420的内部空间421与补液仓200的内部空间(即，储液空间210)之间进行物质交换的“窗口”。该出液孔422可使壳体420的内部空间421与补液仓200的内部空间的液面保持一致，且使壳体420内的液体易于扩散至补液仓200内。
由于壳体420设置于补液仓200的内部空间，且通过位于壳体420底部的出液孔422与补液仓200相连通，壳体420内的液体能够依靠自身重力向下通过出液孔422并回流至补液仓200内，这使得回收过程简易有效。
壳体420上开设有用于连通排气口112与壳体420的内部空间421的进气孔423。电解除氧系统2还可以进一步地包括输气管600，其一端连通排气口112，另一端连通进气孔423，用于将来自排气口112的气体导引至进气孔423。
利用输气管600连接排气口112与进气孔423，可以简化排气口112与进气孔423之间的输气管路的连接结构，提高装配过程的灵活性。
在一些可选的实施例中，过滤部440为导气管，自进气孔423插入壳体420的内部空间421，并延伸至壳体420内的底部区段，以将来自排气口112的气体导引至壳体420内的底部区段，使得来自排气口112的气体中的特定物质成分在上升过程中溶解于壳体420的内部空间421。本实施例的导气管可为直管，其两端均为开口，以便于通入或流出气体，结构简单，具备较优的导气效果。
使导气管延伸至壳体420内的底部区段，可使导气管将气体输送至壳体420内的液体深处，从而延长气体在壳体420内的流动路径，流出导气管的气体在上升过程中能够与壳体420内的液体充分接触，使得气体中的特定物质成分溶解于壳体420内，这使得电解除氧系统2能以精巧简单的结构获得较优的过滤净化以及回收效果。
在一些可选的实施例中，导气管的形状可以变换为竖弯钩状管，且其具有延伸至壳体420的底部区段的直管段以及自直管段的末端弯折向上延伸形成的弯管段。弯管段的末端略高于直管段的末端，用于将流经其的气体向上导引。直管段类似于伞杆，弯管段类似于连接至伞杆末端的伞柄。使弯管段从直管段的末端弯折向上延伸，这可使流出导 气管的气体被导引着向上流动，从而使得气体的运动方向更加明确。弯管段的末端略高于直管段的末端是指，弯管段的末端仍然处在壳体420的底部区段中，这不会明显缩短气体在溶解过程的流动路径。
壳体420上还开设有出气孔424，与进气孔423相互间隔地位于壳体420的顶部，用于排放流经导气管以及壳体420的内部空间且被分离出特定物质成分的气体。该出气孔424用于将过滤后的气体排至外部环境，例如可以排放至外部环境的空气中。
在一些实施例中，进气孔423和出气孔424可以分别位于壳体420的顶盖上。进气孔423和出气孔424可以分别为圆形开口。本实施例的进气孔423和出气孔424可以分别为管状通孔。导气管和进气孔423可以为一体件。进气孔423的管孔孔壁可以向下连贯地延伸并伸入壳体内，作为导气管。在一些实施例中，出气孔424处可以连接有出气导管，用于导引气体。
在一些可选的实施例中，壳体420可为一体成型。在另一些可选的实施例中，壳体420可由多个不同的部件连接而成。例如壳体420可包括具有顶部开口的第一仓体426以及封闭第一仓体426的顶部开口的第一仓盖428。且进气孔423和出气孔424相互间隔地位于第一仓盖428上。第一仓体426可以为直管状，其管径大于导气管的管径。第一仓体426的顶端为开口状，且与第一仓盖428之间密封连接。第一仓体426的底端为闭合状，且其上开设有上述出液孔422。出液孔422可以为至少一个。
进气孔423连同导气管、以及出气孔424，被第一仓体426所包覆，形成套管结构。导气管的底端高于第一仓体426的底端，防止流出导气管的气体逃逸出第一仓体426。
在一些可选的实施例中，补液仓200可为一体成型，这有利于提高补液仓200的密封效果，防止漏液。在另一些可选的实施例中，补液仓200可由多个不同的部件连接而成。例如补液仓200可包括具有顶部开口的第二仓体260以及封闭第二仓体260的顶部开口的第二仓盖280。第二仓体260可以为无盖的长方体水槽状，其容积大于第一仓体426的容积。
图12是图10所示的电解除氧系统2的补液仓200和过滤机构400的过滤回收过程的示意图。
图中箭头方向示出气体流动方向，或者液体的流动方向。由于壳体420这一“隔气管”的限制，流出导气管的气体只能以气泡的形式在第一仓体426的内部上升，直至到达位于第一仓体426上方的第一仓盖428的出气孔424并被排出，从而完成过滤过程。在一些可选的实施例中，上述螺接紧固的安装方式也可以变换为过盈配合或者采用密封圈进行密封连接等方式，只要保证密封不漏水不透气即可。
当来自从排气口112排放的气体含有可溶性的酸性物质或碱性物质时，这些特定物质成分被过滤留在了第一仓体426中，并逐渐通过第一仓体426底部的出液孔422，从而扩散到第二仓体260内的液体中。第一仓体426可作为补液仓，其内部的液体可以通过补液的形式再次输送至反应容器，从而实现再利用。
图13是图10所示的电解除氧系统2的补液仓200的第二仓盖280的示意性结构图。其中，图13(a)为立体图，图13(b)为主视图，图13(c)为俯视图。
第二仓盖280上开设有安装口282。安装口282的孔壁向上延伸形成有中空筒状的外螺纹接口288。由于该外螺纹接口288从安装口282的孔壁向上延伸形成，因此，外螺纹接口288的上边缘高于第二仓盖280的上表面，同时高于下述加液槽286的上边缘。这 可将加液过程的最高液位控制在外螺纹接口288的上边缘以下。
第一仓盖428具有位于第一仓体426上方的封闭盖板428a以及从封闭盖板428a的外周缘向下延伸形成的环状内螺纹接口428b。其中，封闭盖板428a用于遮蔽第一仓体426的顶部开口。环状内螺纹接口428b与外螺纹接口288进行螺接，使得第一仓盖428与第二仓盖280可拆卸地连接。即，环状内螺纹接口428b用于将第一仓盖428连接至第二仓盖280。
第一仓体426自封闭盖板428a的下表面向下延伸，穿过外螺纹接口288之后插入补液仓200内。
利用第一仓盖428与第二仓盖280进行螺接以封闭安装口282，可以简化过滤机构400的安装固定过程，实现一步安装到位，同时还可使第一仓体426发挥“隔气管”作用。
在一些可选的实施例中，第二仓盖280上可以开设有加液口284，其口壁向下延伸形成加液槽286。由于该加液槽286自第二仓盖280的上表面向下延伸，而外螺纹接口288自第二仓盖280的上表面向上延伸，因此，当从加液口284向第二仓体260添加液体时，即使加液过程导致第二仓体260溢液，溢液时的液面不会超过外螺纹接口288。
加液槽286的一部分槽壁倾斜向下延伸设置，使加液槽286的底部形成渐缩的开口。也就是说，加水槽为具有一定深度的倾斜通孔，这便于用户在加液时观察液位情况。倾斜向下延伸的槽壁上具有液位标识，以提示加液过程的液位。例如，该液位标识可被设计为“最高液位刻度线”，用于提示用户液体已注满。
在第二仓体260的底部区段开设供液口262，可使第二仓体260内的液体依靠重力自动流出，这有利于提高供液过程的自动化程度。
在一些可选的实施例中，第二仓盖280的边缘具有向外凸出以供施力的突起287。用户可通过抓取等动作向第二仓盖280施力，从而实现第二仓盖280与第二仓体260之间的拆装过程。
第二仓盖280与第二仓体260之间的闭合处的周缘可设置有弹性密封圈，便于通过第二仓盖280与第二仓体260之间的压合实现密封，以防第二仓体260漏水。
本发明的电解除氧系统2及其控制方法以及冰箱1，由于电解除氧系统2可以根据电解除氧装置100的电解液消耗量确定电解除氧装置100的工作时长，并根据工作时长确定是否提示更换电解除氧装置100的工作元件，因此，本发明提供了一种电解除氧装置100的状态监测手段，控制逻辑简单而巧妙，有利于降低状态监测难度。
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。
