根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。
附图说明
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解，这些附图未必是按比例绘制的。附图中：
图1是根据本发明一个实施例的冰箱的示意性框图；
图2是根据本发明一个实施例的冰箱的电解除氧装置的示意性结构图；
图3是根据本发明一个实施例的冰箱的控制方法的示意图；
图4是根据本发明一个实施例的冰箱的控制流程图。
具体实施方式
图1是根据本发明一个实施例的冰箱1的示意性框图。冰箱1一般性地可包括电解除氧装置10、处理器810和存储器820，还可以进一步地包括箱体，用于安装电解除氧装置10、处理器810和存储器820。
箱体的内部形成有储物空间。储物空间的数量可根据实际需要设置为一个或多个。
图2是根据本发明一个实施例的冰箱1的电解除氧装置10的示意性结构图。
电解除氧装置10包括多个除氧单元，即，强效除氧单元110和多个低 效除氧单元120，分别用于在电解电压的作用下通过电化学反应消耗冰箱1的储物空间的氧气。多个低效除氧单元120串联设置，强效除氧单元110与串联的多个低效除氧单元120并联设置。
在强效除氧单元110和多个低效除氧单元120均接通电解电压的情况下，强效除氧单元110的电化学反应速率高于任一低效除氧单元120的电化学反应速率，且高于全部低效除氧单元120的电化学反应速率之和，或者可以大致等于全部低效除氧单元120的电化学反应速率之和。在一些实施例中，强效除氧单元110和低效除氧单元120的构造和性能参数可以设置为相同。
利用串并联混合的强效除氧单元110和低效除氧单元120形成电解除氧装置，可使电解除氧装置整体的电化学反应速率具有多个不同的值。
强效除氧单元110的数量为一个。在一些可选的实施例中，强效除氧单元110的数量也可以变换为多个，且相互并联设置，这可以提高强效除氧单元110的可替代性，也可使低效除氧单元120和强效除氧单元110之间通过组合得到多种不同的除氧效率。以下实施例将以强效除氧单元110的数量为一个的情况进行示例。
多个除氧单元既可以专门为一个储物空间除氧，也可以同时为多个储物空间除氧，只要保证除氧单元与待除氧的储物空间气流连通即可。气流连通是指，储物空间内的空气可以流动至除氧单元，例如流动至除氧单元的阴极板上，使得阴极板以空气中的氧气作为反应物进行电化学反应，从而起到除氧的作用。以下实施例将以多个除氧单元专门为一个储物空间进行除氧的情况进行示意，本领域技术人员应当易于根据下述实施例进行拓展，因此不再针对其他情况进行示例。
除氧单元一般性地可包括阳极板和阴极板。阴极板用于在电解电压的作用下通过电化学反应消耗氧气。阳极板用于在电解电压的作用下通过电化学反应向阴极板提供反应物(例如，电子)且生成气体。在通电情况下，例如，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 -可以在阳极板处发生氧化反应，并生成氧气，即：4OH -→O 2+2H 2O+4e -。
阴极板具有阴极接线端子。阳极板具有阳极接线端子。相邻低效除氧单元120的阴极接线端子与阳极接线端子相连，这可使多个低效除氧单元120依次串联连接。位于端部的低效除氧单元120的阴极接线端子、以及强效除 氧单元110的阴极接线端子分别与供电电源的负极相连，位于端部的低效除氧单元120的阳极接线端子、以及强效除氧单元110的阳极接线端子分别与供电电源的正极相连，从而使强效除氧单元110与多个低效除氧单元120并联设置。
处理器810和存储器820用于形成冰箱1的控制装置，该控制装置可以为冰箱1的主控板。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冰箱1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820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冰箱1的控制方法的示意图。该控制方法一般性地可包括如下步骤：
步骤S302，获取储物空间的除氧模式。冰箱1可以针对储物空间预先设定多个除氧模式，每个除氧模式可以分别对应有各自的除氧速率，使冰箱1的除氧速率具有多样化的选择。
步骤S304，根据除氧模式选择性地启动多个低效除氧单元120和强效除氧单元110中的至少一个。即，根据除氧模式选择需要启动的除氧单元，并利用这些启动的除氧单元在电解电压的作用下进行电化学反应以消耗储物空间的氧气。
本实施例的控制方法，由于强效除氧单元110与多个低效除氧单元120并联设置，强效除氧单元110和低效除氧单元120可通过组合形成多种启动方案，使冰箱1的除氧速率多元化，因此，通过根据除氧模式选择性地启动多个低效除氧单元120和强效除氧单元110中的至少一个来消耗储物空间的氧气，可使冰箱1根据储物空间的实际除氧需求进行除氧，这有利于提高冰箱1除氧过程的灵活性。
在一些可选的实施例中，根据除氧模式选择性地启动多个低效除氧单元120和强效除氧单元110中的至少一个的步骤包括：获取与除氧模式相对应的组合规则，按照组合规则启动强效除氧单元110和多个低效除氧单元120 中的至少一个。
也就是说，每个除氧模式分别设置有各自对应的组合规则，组合规则中规定了在该除氧模式下需要启动的强效除氧单元110和低效除氧单元120。
使用上述方法，通过预设组合规则，并在确定出除氧模式的情况下，按照与除氧模式相对应的组合规则启动除氧单元，可以简化冰箱1的控制逻辑，提高控制效率。
本实施例中，储物空间的除氧模式包括强效模式、中效模式和低效模式。顾名思义，强效模式是指除氧效果最强的模式，其除氧速率最高，中效模式是指除氧效果中等的模式，其除氧速率中等，低效模式是指除氧效果最低的模式，其除氧效率最低。
组合规则规定有与对应除氧模式相适配的低效除氧单元120的启动数量和强效除氧单元110的启动数量。在一些实施例中，每个除氧单元还分别预设有各自的编号，组合规则还可以规定有与对应除氧模式相适配的需要启动的低效除氧单元120的编号和需要启动的强效除氧单元110的编号。
例如，当储物空间的除氧模式为强效模式时，可以选择启动全部低效除氧单元120和强效除氧单元110，当储物空间的除氧模式为中效模式时，可以选择启动强效除氧单元110，当储物空间的除氧模式为低效模式时，可以选择启动全部低效除氧单元120。
在一些可选的实施例中，在按照组合规则启动强效除氧单元110和多个低效除氧单元120中的至少一个的步骤之后，还包括：检测强效除氧单元110和每一低效除氧单元120的衰减程度，根据衰减程度调整与每一除氧模式相对应的组合规则。
由于强效除氧单元110和低效除氧单元120不可避免地会发生性能衰减，通过检测强效除氧单元110和每一低效除氧单元120的衰减程度，并根据衰减程度调整与每一除氧模式相对应的组合规则，可使冰箱1及时地调整除氧策略，保证除氧效果，提升了冰箱1的智慧化程度。
除氧单元的衰减程度是相对于未发生性能衰减的除氧单元而言的，例如，可以按照电化学反应速率的衰减程度来衡量对应除氧单元的衰减程度。当除氧单元的电化学反应速率衰减为未发生性能衰减时的电化学反应速率的一半时，该除氧单元的衰减程度为50％。
在一些可选的实施例中，检测强效除氧单元110和每一低效除氧单元 120的衰减程度的步骤包括：分别获取强效除氧单元110和每一低效除氧单元120进行电化学反应时的实际电参数，根据各自的实际电参数分别确定强效除氧单元110和每一低效除氧单元120的衰减程度。
例如，在上述步骤S304之后，且在启动的低效除氧单元120和强效除氧单元110停止进行电化学反应后，通过获取低效除氧单元120和强效除氧单元110的运行记录，可以得到强效除氧单元110和每一低效除氧单元120进行电化学反应时的实际电参数。
在一些实施例中，在上述步骤S304之后，且在启动的低效除氧单元120和强效除氧单元110正在进行电化学反应时，也可以同时检测并获取强效除氧单元110和每一低效除氧单元120的实际电参数。
除氧单元进行电化学反应的实际电参数可以指进行电化学反应时的实际电解电压或者实际工作电阻或者实际工作电流。由于进行电化学反应时的除氧单元相当于电学元件，因此，根据实际电参数来确定除氧单元的衰减程度，方法简便，计算结果准确可靠。
例如，每一低效除氧单元120的两端可以并联设置一电压检测器610，用于检测低效除氧单元120进行电化学反应时的实际电解电压，并可将低效除氧单元120的实际电解电压作为其实际电参数；强效除氧单元110可以串联设置有一电流检测器620，用于检测其进行电化学反应时的实际工作电流，并可将强效除氧单元110的实际工作电流作为其实际电参数。
根据各自的实际电参数分别确定强效除氧单元110和每一低效除氧单元120的衰减程度的步骤包括：分别获取未衰减的强效除氧单元110和未衰减的低效除氧单元120的标准电参数，分别根据各自的实际电参数和各自的标准电参数确定强效除氧单元110和每一低效除氧单元120的衰减程度。本实施例中，未衰减的除氧单元可以指全新的除氧单元，或者可以指服役时长小于预设时长阈值的除氧单元，通过对未衰减的除氧单元进行电化学反应时的电参数进行检测，得到标准电参数。例如，强效除氧单元110的标准电参数可以为标准工作电流，低效除氧单元120的标准电参数可以为标准电解电压。
在分别根据各自的实际电参数和各自的标准电参数确定强效除氧单元110和每一低效除氧单元120的衰减程度的步骤中，例如，当确定强效除氧单元110的衰减程度时，可将强效除氧单元110的实际工作电流与标准工作电流之间的比值作为其衰减程度，当确定低效除氧单元120的衰减程度时， 可将低效除氧单元120的实际电解电压与标准电解电压之间的比值作为其衰减程度。
使用上述方法，通过预设标准电参数，并利用标准电参数与实际电参数计算除氧单元的衰减程度，可以有针对性地得到每个除氧单元的衰减程度，为合理调整组合规则提供数据支持。
在一些可选的实施例中，根据衰减程度调整与每一除氧模式相对应的组合规则的步骤包括：获取与每一组合规则相对应的预设除氧速率，根据强效除氧单元110和每一低效除氧单元120的衰减程度分别计算强效除氧单元110和每一低效除氧单元120的实际除氧速率，按照实际除氧速率对强效除氧单元110和多个低效除氧单元120进行匹配组合，得到调整后的组合规则，且使调整后的每一组合规则相对应的实际除氧速率分别达到对应预设除氧速率。
除氧单元的除氧速率亦即电化学反应速率，也为储物空间的氧气消耗速率。每一组合规则对应的预设除氧速率根据未衰减的除氧单元的标准除氧速率进行确定。通过在设定时间段内对未衰减除氧单元进行电化学反应过程的储物空间氧气浓度进行测定，可以得到标准除氧速率。实际除氧速率根据衰减程度进行确定，例如，当除氧单元的衰减程度为50％时，其实际除氧速率对应衰减为标准除氧速率的50％。
在按照实际除氧速率对强效除氧单元110和多个低效除氧单元120进行匹配组合的过程中，例如，当强效除氧单元110和全部低效除氧单元120的实际除氧速率均衰减50％时，若与中效模式相对应的原始的组合规则为1个强效除氧单元110加0个低效除氧单元120(即，仅启动强效除氧单元110)，则调整后的组合规则可以为1个强效除氧单元110加全部低效除氧单元120(即，启动强效除氧单元110和全部低效除氧单元120)。
按照实际除氧速率对组合规则进行调整，且使调整后的每一组合规则的实际除氧速率分别达到对应的预设除氧速率，可以保证组合规则的调整过程达到良好的效果，使组合规则始终与除氧模式相对应。
在一些可选的实施例中，在检测强效除氧单元110和每一低效除氧单元120的衰减程度的步骤之后，控制方法还可以包括：判断强效除氧单元110或者低效除氧单元120是否达到老化程度，若是，则输出提示信号，以提示用户进行更换或维修。例如，当除氧单元的衰减程度达到80％～90％时，即 可判定除氧单元达到老化程度，此时，通过输出提示信号，可以提示用户尽快地采取补救措施，以保证利用多个除氧单元能够匹配出与各个除氧模式相对应的组合规则。上述步骤可以在根据衰减程度调整与每一除氧模式相对应的组合规则之前执行。
在一些可选的实施例中，获取储物空间的除氧模式的步骤包括：获取储物空间的氧气浓度，根据氧气浓度确定储物空间的除氧模式。例如，可以采用氧气浓度传感器检测储物空间的氧气浓度，在氧气浓度处于较高水平时，可以选择强效模式，在氧气浓度处于中等水平时，可以选择中效模式，在氧气浓度处于较低水平时，可以选择低效模式。
在另一些可选的实施例中，还可以根据储物空间的开放时长来确定除氧模式，这可以省略布置氧气浓度传感器。储物空间的开放时长能够间接地反映出储物空间氧气浓度的高低，在一定时长范围内，储物空间的氧气浓度随开放时长的缩短而降低。
在一些可选的实施例中，每一除氧单元分别对应设置有单元开关元件520，用于受控地开闭，从而使除氧单元断电或者接通电解电压。每一低效除氧单元120还对应设置有替代元件512，设置在与对应低效除氧单元120并联的调整支路510上，且调整支路510上还设置有调整开关元件511，用于受控地开闭，从而使替代元件512断电或者接入电路。
在一些进一步的实施例中，若某一低效除氧单元120达到老化程度，可以断开与该低效除氧单元120对应的单元开关元件520，且闭合与该低效除氧单元120对应的调整开关元件511，使得替代元件512代替该低效除氧单元120接入电路。
使用上述方法，冰箱1可以自动地针对老化的低效除氧单元120可能导致的关联性性能衰减进行补救，减少或避免其他低效除氧单元120的性能急剧衰减，有利于提高多个低效除氧单元120的有效工作寿命，提升冰箱1的智慧化程度。
在一些可选的实施例中，替代元件512为电阻，其阻值根据对应低效除氧单元120处于未衰减状态时的平均阻值进行设置。

步骤S402，获取储物空间的氧气浓度。
步骤S404，根据氧气浓度确定储物空间的除氧模式。储物空间的除氧模式包括强效模式、中效模式和低效模式。
