具体实施方式
图1是根据本发明一个实施例的冰箱10的示意性结构图。图2是根据本发明一个实施例的冰箱10的示意性框图。冰箱10一般性地可包括箱体500、电解除氧装置100和加热装置300。
箱体500的内部形成储物空间510，用于存放食材、药品或者其他物品。储物空间510的数量可以根据实际需要设置为一个或多个。图1仅以具有三个储物空间510的冰箱10进行示例，但不应视为对储物空间510数量的限定。下述电解除氧装置100可以根据实际需要布置于任一储物空间510，或与任一储物空间510对应地气流连通，以消耗该储物空间510的氧气。
电解除氧装置100，与储物空间510气流连通，配置成在电解电压的作用下通过电化学反应消耗储物空间510内的氧气。气流连通是指，储物空间510内的气体能够流动至电解除氧装置100，使得电解除氧装置100能以储物空间510内的氧气为反应物进行电化学反应，从而起到除氧的作用。
电解除氧装置100的电化学反应类型可以根据实际需要进行设置，只要电化学反应能够起到消耗氧气的作用均可。例如，电化学反应可以为电解水的反应。
加热装置300与电解除氧装置100热连接，配置成加热电解除氧装置100。热连接是指，加热装置300所产生的热量能够传递至电解除氧装置100。
本发明的冰箱10，通过使电解除氧装置100与加热装置300热连接，并利用加热装置300加热电解除氧装置100，可以解决因低温所导致的电解除氧装置100失效问题。即使冰箱10内的储物空间510温度较低，利用加热装置300所产生的热量也可使电解除氧装置100保持相对较高温度，从而保证电解除氧装置100能够正常地进行电化学反应。本发明的方案，尤其适用于电解除氧装置安装于冷冻空间并为冷冻空间除氧的应用场景。
发明人认识到，除了失效问题之外，低温环境可能还会导致电解除氧装置100的结构出现损伤甚至破裂。利用加热装置300与电解除氧装置100热 连接，以加热电解除氧装置100，可以避免电解除氧装置100因低温而“冻坏”，有利于使电解除氧装置100保持良好的结构稳定性，延长电解除氧装置100的使用寿命，降低维修更换频率。
利用加热装置300与电解除氧装置100热连接，彻底规避了因低温环境所导致的电化学反应无法正常进行、以及电解除氧装置100出现结构损伤等问题，具备结构精巧、效果显著的优点。
加热装置300可以根据实际需要设置为能够产生热量的任一装置，例如可以为电加热装置300、高频加热装置300等，只要能够具备发热功能均可。
在一些可选的实施例中，加热装置300为电热元件，配置成在通电状态下产生热量，从而加热电解除氧装置100。电热元件属于电加热装置300。加热装置300可以通过导线接入冰箱10整机的电路板，从而接受控制。
采用电热元件充当加热装置300，只要保证电热元件与电解除氧装置100“接触”，即可实现热连接，同时通过对电热元件供电，并使其在通电状态下产生热量，即可起到加热的目的，具备结构简单、易于实现热连接、控制过程简易、制造成本低等优点。
在一些进一步的实施例中，电热元件为电热丝或电热片，缠绕或嵌设于电解除氧装置100，或与电解除氧装置100贴靠设置，以实现热连接。即，电热元件与电解除氧装置100之间的热连接方式可以为缠绕、嵌设或者贴靠等多种方式中的任意一个。下面将以电热丝为例，针对电热元件与电解除氧装置100之间的连接结构进行示意，本领域技术人员在了解下述实施例的基础上应当易于变换和拓展，这些变换和拓展均应落入本发明的保护范围。
图3是根据本发明一个实施例的冰箱10的加热装置300与电解除氧装置100的示意性连接结构图，图4是图3所示的冰箱10的加热装置300的示意性结构图。图中的黑色圆点示出加热装置300的接线端子，用于与导线连接，以接入冰箱10整机的电路板。本实施例以加热装置300为电热丝进行示例。当电热元件为电热丝时，电热元件可以缠绕设置于电解除氧装置100的壳体110外壁上，或者可以嵌设于电解除氧装置100的壳体110的内部空间，或者还可以嵌设于电解除氧装置100的壳体110的壳壁内。

阴极板120设置于连通口114处，以与壳体110共同限定出用于盛装电解液的储液腔，并用于在电解电压的作用下通过电化学反应消耗储物空间510内的氧气。将阴极板120设置于连通口114处，在封闭储液腔的同时，可保证阴极板120与储物空间510气流连通。例如，空气中的氧气可以在阴极板120处发生还原反应，即：O 2+2H 2O+4e -→4OH -。储液腔缩盛装的电解液可以为酸性水溶液或者碱性水溶液，例如可以为1～5mol/L的氢氧化钠溶液。
阳极板140设置于储液腔内，并用于通过电化学反应向阴极板120提供反应物。阳极板140与阴极板120相互间隔地设置于储液腔内。且在通电情况下，阳极板140用于通过电化学反应向阴极板120提供反应物(例如，电子)且生成氧气。又如，阴极板120产生的OH -在阳极板140处可以发生氧化反应，并生成氧气，即：4OH -→O 2+2H 2O+4e -。壳体110上还可以开设有排气口112，氧气可以通过排气口112排出。
电热元件缠绕于壳体110的外表面，或者通过注塑成型嵌设于壳体110的壳壁，或者设置于储液腔内。电热元件可以为电热丝或电热片，或者任意其他形状的电热元件。
将电热元件缠绕于壳体110的外表面，可以降低电热元件的检修难度，当电热元件的加热效率下降时，可以十分简便地更换电热元件。

由于保温装置700包裹在加热装置300与电解除氧装置100的外侧，可以起到防止加热装置300和电解除氧装置100所产生的热量泄漏的作用，因此，本实施例的方案，能够减少或避免因加热装置300和电解除氧装置100所产生的热量扩散至储物空间510所导致的保鲜效果变差问题。
在一些进一步的实施例中，保温装置700的内部限定出空腔750，以容置加热装置300以及电解除氧装置100。且保温装置700由内至外地包括第一保温层710、第二保温层720以及第三保温层730。即，保温装置700由多层材料制成，多层材料由内至外地层层叠置，从而限定出空腔750。
其中，第一保温层710由复合玻璃材料制成，例如复合玻璃纤维布。第二保温层720由橡塑保温材料或者真空绝热材料制成，其中，橡塑保温材料的防火性能等级为A级，真空绝热材料可以采用真空绝热板。第三保温层730由橡塑材料制成，例如橡塑胶带。
将第一保温层710、第二保温层720以及第三保温层730由内至外地层层叠置，从而形成保温装置700，既可以防止热量泄漏，又可以提高电解除 氧装置100对加热装置300所提供热量的利用效率，一举多得。
在一些可选的实施例中，保温装置700与加热装置300可以一体成型，形成电伴热保温系统。其中，加热装置300作为电伴热保温系统的电伴热带，贴靠设置在第一保温层710背朝第二保温层720的一侧，即，位于多层结构的最内侧。在一些可选的实施例中，电热元件还可以嵌设于第一保温层710内(电热元件的嵌设位置如图8虚线所示)。
利用一体成型的电伴热保温系统加热电解除氧装置100，并实现保温功能，可以进一步地提高加热模块和保温模块的结构一体性，降低冰箱10的组装难度。
在一些可选的实施例中，冰箱10还可以包括温度传感器(未示出)，设置于保温装置700的空腔750内，用于检测空腔750内的温度，空腔750内的温度即可视为电解除氧装置100的温度。加热装置300可以配置成在温度传感器所检测到的温度低于预设的第一温度阈值时受控地启动，从而切换至通电状态并产生热量。如此设置，可使空腔750内的温度基本保持恒定，以防电解除氧装置100的温度产生明显波动，避免电解除氧装置100因温度明显下降而产生电化学反应无法进行或者产生结构缺陷等问题。
在一些可选的实施例中，保温装置700开设有连通空腔750的开口，以允许位于空腔750内的电解除氧装置100通过开口与储物空间510气流连通。例如，保温装置700的外形大致呈中空的长方体状，开口可以位于保温装置700的侧壁上，且与壳体110的连通口114相对。
在一些可选的实施例中，冰箱10还包括控制装置900，与加热装置300数据连接。控制装置900用于向加热装置300发送加热启动信号，以启动加热装置300。例如，控制装置900可以配置成按照预设的周期向加热装置300发送加热启动信号，使得加热装置300周期性通电并产生热量，以使电解除氧装置100的温度基本保持恒定。本实施例的控制手段可以适用于储物空间510为冷藏空间或者冷冻空间的情况，尤其适用于储物空间510为冷冻空间的应用场景。
又如，控制装置900可以与以上实施例所提到的温度传感器数据连接，并在电解除氧装置100的温度(即，温度传感器所检测到的温度)低于预设的第一温度阈值时向加热装置300发送加热启动信号，使加热装置通电并产生热量，以保证电解除氧装置100的温度始终处于预设的第一温度阈值以上。 本实施例的控制手段既可以适用于储物空间510为冷藏空间的情况，也可以适用于储物空间510为冷冻空间的情况，尤其适用于储物空间510为冷冻空间的应用场景，，为使电解除氧装置100在冷冻空间内正常地执行除氧工作创造了有利条件。在温度传感器所检测到的温度高于预设的第二温度阈值时，控制装置900向加热装置300发送停机信号，以使加热装置300停止加热。第二温度阈值高于第一温度阈值，例如，第一温度阈值可以为-5℃，第二温度阈值可以为0℃。
在一些可选的实施例中，控制装置900还可以配置成在启动电解除氧装置100之前向加热装置300发送加热启动信号，使得加热装置300通电并产生热量。在启动电解除氧装置100之前启动加热装置300，可使电解除氧装置100的温度升高至合理水平，以保证电化学反应正常进行。
例如，冰箱10的储物空间510内设置有氧气浓度传感器，该氧气浓度传感器与冰箱10的控制装置900数据连接，用于检测储物空间510内的氧气浓度。在储物空间510的氧气浓度高于预设的浓度阈值时，确定需要启动电解除氧装置100，在启动电解除氧装置100之前，先执行启动加热装置300的步骤，并使加热装置300运行设定时长之后，再执行启动电解除氧装置100的步骤，这可以在一定程度上降低加热装置300的功耗。又如，控制装置900可与电解除氧装置100数据连接，配置成在氧气浓度传感器的检测值高于预设的浓度阈值且加热装置300运行设定时长之后向电解除氧装置100发送除氧启动信号，使得电解除氧装置100通电并启动除氧。本实施例的控制手段适用于储物空间510为冷藏空间的情况，冷藏空间的温度相对较高，电解除氧装置100一般不具有冻结风险。当电解除氧装置100在冷冻空间内不具备冻结风险或者不会因冻结而导致结构损伤时，本实施例的控制手段也可以适用于储物空间510为冷冻空间的情况。
在一些可选的实施例中，冰箱10还包括状态监测装置600，设置于电解除氧装置100所在的供电回路上，用于检测电解除氧装置100启动之后的工作电流。例如，冰箱10内设置有供电电源，作为供电回路的电源，并向电解除氧装置100提供进行电化学反应所需的电解电压。电解除氧装置100串接在供电回路上。在一些实施例中，供电电源可以为电池，或者可以为冰箱10整机的电路板的一部分。
如果电解液因低温而冻结或者部分冻结，当向电解除氧装置100供电之 后，会导致状态监测装置600检测不到电流或者电流很小。控制装置900还配置成在电解除氧装置100的工作电流低于预设的电流阈值时向加热装置300发送加热启动信号。也就是说，在电解除氧装置100进行电化学反应的过程中，加热装置300也可以根据实际需要而受控地启动。
通过利用状态监测装置600检测电解除氧装置100启动之后的工作电流，并在电解除氧装置100的工作电流低于预设的电流阈值时启动加热装置300，可使电解除氧装置100的电化学反应速率加快，从而保证电解除氧装置100始终维持相对较高的除氧效率。
状态监测装置600可以为电流检测器，与电解除氧装置100串联设置于供电回路上。在启动加热装置300之后，当状态监测装置600检测到的电流值达到预设的电流阈值时，控制装置900可以向加热装置300发送停机信号，电解除氧装置100进行电化学反应时所产生的热量能够在一定程度上维持自身的温度。
以上关于状态监测装置600和利用工作电流判定是否需要启动加热装置300的举例仅仅是示例性的，在了解以上举例的基础上，本领域技术人员应当易于拓展和变换，这些拓展和变换均应落入本发明的保护范围。例如，状态监测装置600可以变换为电阻检测器，用于检测电解除氧装置100的电阻值，控制装置900可以配置成在电解除氧装置100的电阻值高于预设的阻值阈值时向加热装置300发送加热启动信号。
在一些可选的实施例中，温度传感器的安装位置可以进行变换，例如可以设置于储物空间510内。由于电解除氧装置100会长时间地放置于储物空间510内，因此，储物空间510的温度大致等于电解除氧装置100的温度。根据储物空间510的温度即可判断是否需要加热电解除氧装置100，方法便捷，无需在空腔750内布置温度检测装置，有利于简化冰箱10的结构、降低组装难度，节约整机的制造成本。
图9是图3所示的冰箱10的电解除氧装置100的示意性分解图。下面将针对电解除氧装置100的结构进行进一步示例。
壳体110上开设有排气口112，用于允许壳体110内产生的气体排出至外部空间。本实施例的阳极板140在进行电化学反应时生成氧气，上述排气口用于允许阳极板140生成的氧气排出。排气口112可以靠近壳体110的顶部设置，这可以减少或避免电解液泄漏。在一些实施例中，排气口112处可 以连接有排气管160。
阳极板140上形成有阳极供电端子142。以与供电电源相连。
在一些实施例中，电解除氧装置100还可以进一步地包括分隔件130和固定组件150。其中，分隔件130设置于储液腔内，并位于阴极板120与阳极板140之间，用于分隔阴极板120与阳极板140，防止电解除氧装置100短路。具体地，分隔件130上朝向阳极板140的一侧形成有多个凸起部132，凸起部132抵触于阳极板140上，阴极板120贴靠于分隔件130背离凸起部132的一侧，以在阴极板120与阳极板140形成预设间隙，进而将阴极板120与阳极板140分隔开。
固定组件150可以设置于阴极板120的外侧，配置成将阴极板120固定于壳体110的连通口114处。具体地，该固定组件150还可以包括金属边框152和支撑件154。金属边框152贴靠于阴极板120的外侧。金属边框152与阴极板120直接接触，可以起到压紧阴极板120的作用，并且金属边框152上还可以设置有阴极板120的阴极供电端子152b，以与外部电源相连。支撑件154形成有插接槽。当金属边框152的围立部152a进支撑件154的插接槽时，金属边框152可以由支撑件154固定和定位，进而使得金属边框152压紧阴极板120。
当电热元件设置于储液腔内时，电热元件可以位于分隔件130与阳极板140之间。
以上仅是针对电解除氧装置100的结构进行举例，但不应视为电解除氧装置100的结构仅限于此。
本发明的冰箱10，通过使电解除氧装置100与加热装置300热连接，并利用加热装置300加热电解除氧装置100，可以解决因低温所导致的电解除氧装置100失效问题。即使冰箱10内的储物空间510温度较低，利用加热装置300所产生的热量也可使电解除氧装置100保持相对较高温度，从而保证电解除氧装置100能够正常地进行电化学反应。本发明的方案，尤其适用于电解除氧装置安装于冷冻空间并为冷冻空间除氧的应用场景，为使电解除氧装置在冷冻空间内正常地执行除氧工作创造了有利条件。
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。
