本发明的冰箱，由于电解除氧装置与送风口相对，流经送风口的制冷气流可以对电解除氧装置进行降温，减少或避免电解除氧装置及其周围部件因温度过高而发生意外，因此，本发明的冰箱具备优异的安全性能。

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结构图；
图2是图1中A处的局部放大图；
图3是根据本发明一个实施例的冰箱的隔离器件的示意性结构图；
图4是根据本发明一个实施例的冰箱的安全容器与电解除氧装置的装配图；
图5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6是图5所示的冰箱的电解除氧装置的示意性分解图。
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。冰箱10一般性地可包括箱体100和电解除氧装置200。为了较好地展现冰箱10内部结构，图1以透视图的形式绘制，并以侧视图呈现。
其中，箱体100的内部限定出储物间室112以及送风风道118。送风风道118通过送风口116向储物间室112提供制冷气流。也就是说，储物间室112和送风风道118通过送风口116连通，使得储物间室112可接收来自送风风道118的制冷气流，从而调节温度。
储物间室112可以为一个或多个。电解除氧装置200可以选择性地设置于一个储物间室112内，例如冷藏间室、冷冻间室或者变温间室，对此不做限定。
电解除氧装置200设置在储物间室112内，用于通过进行电化学反应来 消耗储物间室112内的氧气。例如，电解除氧装置200可包括阴极电极和阳极电极，通过对阴极电极和阳极电极通电，两极上可分别发生电化学反应。电化学反应的类型可以任意选择，只要保证某一电极的反应物为氧气即可。例如，阴极电极的电化学反应可以为还原反应，阳极电极的电化学反应可以为氧化反应。
冰箱10可以进一步地包括控制装置900，其与电解除氧装置200电连接，可向电解除氧装置的阴极电极和阳极电极提供电解电压。
电解除氧装置200与送风口116相对，以利用制冷气流进行冷却。通过对电解除氧装置200的安装位置进行改进，当送风风道118向储物间室112供应制冷气流时，流出送风口116的制冷气流会流经电解除氧装置200，从而带走一部分热量。
本实施例的冰箱10，由于电解除氧装置200与送风口116相对，流经送风口116的制冷气流可以对电解除氧装置200进行降温，减少或避免电解除氧装置200及其周围部件因温度过高而发生意外，因此，本实施例的冰箱10具备优异的安全性能。
电解除氧装置200可以为整个储物间室112除氧，也可以为储物间室112内的特定部位除氧。例如，在一些可选的实施例中，冰箱10还可以进一步地包括储物容器300，设置于储物间室112内，且其内部形成储物空间。电解除氧装置200可以与该储物空间气流连通，从而通过进行电化学反应来消耗该储物空间内的氧气。
储物容器300上开设有安装口(图中未示出)，其与送风口116相对。安装口和送风口116的位置可以根据实际需要进行设置，例如，当送风口116位于储物容器300的后侧时，安装口可以开设在储物容器300的背壁上，当送风口116位于储物容器300的横向一侧时，安装口可以开设在储物容器300的相应侧壁上，只要保证送风口116与安装口相对即可。“横向”方向平行于水平方向，且垂直于箱体100的前后延伸方向。
电解除氧装置200设置于安装口处并封闭安装口，以使其面朝储物空间的部分与储物空间气流连通，且使其背朝储物空间的部分与送风口116相对。也就是说，安装口可起到定位作用，利用安装口定位电解除氧装置200，可以简化电解除氧装置200的安装定位过程。
通过在储物容器300上开设正对送风口116的安装口，并将电解除氧装 置200设置在安装口处，使其封闭安装口，即可使电解除氧装置200与储物空间气流连通，并处于制冷气流的流动路径上，从而达到利用制冷气流冷却电解除氧装置200的目的，具备结构简单、制造成本低的优点。
在一些进一步的实施例中，冰箱10还可以进一步地包括风机500，设置于储物容器300内，用于促使形成流经或流向安装口的气流。在风机500的作用下，储物容器300内的空气快速搅动，并流经或流向安装口312，从而可提高电解除氧装置200的除氧效率，并保证储物容器300内的气体均匀性。该风机500用于促使形成位于储物容器300内的内循环气流，其类型可以根据实际需要进行任意选择，例如可以为微型离心风机500或者微型轴流风机500等。
在一些可选的实施例中，送风口116与储物容器300的背壁相对。安装口开设于储物容器300的背壁上。即，电解除氧装置200设置于储物容器300的背部，一般不会暴露于用户的视觉范围内，这有利于提高冰箱10的美观度。
根据图2所示出的电解除氧装置200的形状和安装位置、以及送风口116的位置，本领域技术人员应当易于获知安装口的位置和形状，因此省略了附图标记。
图2以及以下实施例以电解除氧装置200设置于储物容器300背部的情况为例，对冰箱10结构做进一步介绍，本领域技术人员在了解本公开全部实施例的基础上，应当完全有能力针对其他安装方案进行拓展和变换，因此不再一一示出，需要说明的是，这些拓展和变换均应落入本公开的保护范围。
在一些可选的实施例中，冰箱10还包括隔离器件400，设置在储物容器300内，且包绕于安装口的内侧，以防储物容器300内的物体与电解除氧装置200接触。安装口的内侧和外侧分别是相对于储物空间而言的，安装口的内侧是指安装口面朝储物空间的一侧，安装口的外侧是指安装口背朝储物空间的一侧。隔离器件400包绕于安装口的内侧是指，隔离器件400将安装口内侧的储物空间与安装口间隔开。
图2是图1中A处的局部放大图，图中示出了隔离器件400与电解除氧装置200的装配图。由于可利用隔离器件400包绕安装口，以防储物容器300内的物体与电解除氧装置200接触，因此，本方案的冰箱10可防止电解除氧装置200因与储物容器300内的物体接触而导致损伤。
图3是根据本发明一个实施例的冰箱10的隔离器件400的示意性结构图，该图以主视图视角进行绘制。隔离器件400上开设有允许气体通过的透气孔401，这使得隔离器件400在间隔安装口与其内侧储物空间的同时，不会阻碍气体流通。例如，隔离器件400可以为多孔的罩壳，罩设在安装口的内侧。
在一些实施例中，隔离器件400具有基板410和侧板420。其中，基板410与安装口相对，侧板420从基板410的周缘延伸至安装口的外周，以使隔离器件400罩扣于安装口。基板410与安装口所在平面平行间隔设置。例如，当安装口开设于储物容器300的背壁时，基板410设置于安装口的前侧。基板410的面积可以略大于安装口的面积，以在遮挡于安装口的前侧时，起到全面保护作用。
需要说明的是，“前”“后”“上”“下”等指示方向或位置关系的术语是基于附图所示的方向或位置关系，这仅仅是为了便于描述，而不是指示或暗示所描述的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
安装口的外形、隔离器件400的外形、以及电解除氧装置200的壳体210的外形相适配，并且可以根据实际需要进行任意选择，对此不做具体限定。例如，当安装口为长方形时，相应地，电解除氧装置200的壳体210为长方体形状，以便于完全封闭安装口，隔离器件400的基板410相应设置为长方形状，且侧板420分别从基板410的四个边向后分别延伸至安装口的上端、下端、以及横向两端。
透气孔401开设于基板410上，且为阵列排布的通孔，从而几乎不会影响气体正常通过，保证正常的通气率。并且由于基板410具有较大的面积，因此开孔几乎不会影响其结构稳定性。
在一些进一步的实施例中，通孔的孔径小于预设的孔径阈值，例如，该孔径阈值可以配置成仅允许气体通过，液体或者固体均会被阻止通过，这可以提高隔离器件400的隔离防护效果，避免细小的颗粒物或者液体穿过通孔污染电解除氧装置200。
在一些可选的实施例中，冰箱10还包括安全容器800，设置于电解除氧装置200的下方，用于盛接流出电解除氧装置200的液体，例如电解液。
通过在电解除氧装置200的下方设置安全容器800，使其盛接流出电解 除氧装置200的液体，一旦电解除氧装置200发生漏液，漏出的液体可被集中收集，并不会到处散布。因此，基于本实施例的方案，冰箱10可减少或避免因电解除氧装置200漏液而污染储物环境。
例如安全容器800可被设置为具有顶部开口的容器，该开口与上方的电解除氧装置200相对，以便利用该开口盛接流出电解除氧装置200的液体。
在一些可选的实施例中，安全容器800具有储液部810以及伸展部820。其中，储液部810具有底壁811以及侧壁812，侧壁812从底壁811的周缘向上延伸以与底壁811共同限定出具有顶部开口以供储液的储液部810。伸展部820从储液部810的周壁上表面向上且向外延伸，以形成向上扩张的喇叭口。
本实施例中，“向外延伸”方向是相对于储液部810而言的，并且是指朝向储液部810的外部空间的方向。通过在储液部810的顶部开口处设置喇叭状的伸展部820，可以起到扩大开口面积的作用，提高了安全容器800的防护效果，冰箱10的防泄漏效果较优。
图4是根据本发明一个实施例的冰箱10的安全容器800与电解除氧装置200的装配图。储液部810的侧壁812可以从底壁811的周缘沿竖直方向向上延伸，使得储液部810呈无盖长方体形状。当然，在一些可选的实施例中，如图2和3所示，储液部810的侧壁812也可以从底壁811的周缘沿向上且向外的方向延伸，使储液部810形成口径向上渐扩的容器，这有利于进一步扩大安全容器800的开口面积，从而提升防护效果。
在一些进一步的实施例中，电解除氧装置200竖直设置，且其底部伸入伸展部820所形成的喇叭口内。也就是说，电解除氧装置200的底部处于安全容器800内。通过对电解除氧装置200的姿态和位置进行上述改进，电解除氧装置200本身会对流出的电解液起到导引作用，一旦电解除氧装置200发生漏液，流出的电解液会顺势向下全部流入安全容器800内，不会因无序流动而导致安全事故。并且，由于电解除氧装置200位于安全容器800内，其至少部分地遮蔽安全容器800的开口，因此当储液部810内已存在液体时，电解除氧装置200可以减少或避免液体溅出，从而进一步提高冰箱10的安全系数。
在一些可选的实施例中，储物容器300为抽屉，且其具有筒体310以及可抽拉地设置于筒体310的抽屉本体320。安装口开设于筒体310上。当用 户因取放物品而实施抽拉操作时，装配有电解除氧装置200的筒体310可保持静止，避免抽拉操作对电解除氧装置200的电路连接产生影响。
图5是根据本发明一个实施例的冰箱10的电解除氧装置200的示意性结构图，图6是图5所示的冰箱10的电解除氧装置200的示意性分解图。
电解除氧装置200一般性地可包括壳体210、阴极板220和阳极板230。
其中，壳体210呈扁平的长方体状，壳体210上形成有面朝储物空间的侧向开口211，该侧向开口211位于壳体210的较宽的侧面上。
阴极板220作为电解除氧装置200的阴极电极，用于发生氧气的还原反应。阴极板设置于侧向开口211处，以与壳体210共同限定出用于盛装电解液的储液腔214，并用于通过电化学反应消耗储物容器300内的氧气。例如，空气中的氧气可以在阴极板220处发生还原反应，即：O 2+2H 2O+4e -→4OH -。
阳极板230作为电解除氧装置200的阳极电极，用于发生氧化反应。阳极板设置于储液腔214内，并用于通过电化学反应向阴极板220提供反应物，例如电子。阴极板220产生的OH -可以在阳极板230处可以发生氧化反应，并生成氧气，即：4OH -→O 2+2H 2O+4e -。氧气可以通过壳体210上的排气口218排出。
在一些实施例中，电解除氧装置200还可以进一步地包括分隔件240和固定组件250。
分隔件240设置于储液腔214内，并位于阴极板220与阳极板230之间，用于分隔阴极板220与阳极板230，防止电解除氧装置200短路。具体地，分隔件240上朝向阳极板230的一侧形成有多个凸起部242，凸起部242抵触于阳极板230上，阴极板220贴靠于分隔件240背离凸起部242的一侧，以在阴极板220与阳极板230形成预设间隙，进而将阴极板220与阳极板230分隔开。
固定组件250可以设置于阴极板220的外侧，配置成将阴极板220固定于壳体210的侧向开口211处。具体地，该固定组件250还可以包括金属边框252和支撑件254。
金属边框252贴靠于阴极板220的外侧。金属边框252与阴极板220直接接触，可以起到压紧阴极板220的作用，并且金属边框252上还可以设置有阴极板220的阴极供电端子252b，以与外部电源相连。阳极板230上可以设置有阳极供电端子232，以与外部电源相连。
支撑件254形成有插接槽。当金属边框252的围立部252aa进支撑件254的插接槽时，金属边框252可以由支撑件254固定和定位，进而使得金属边框252压紧阴极板220。
以上实施例的冰箱10，由于电解除氧装置200与送风口116相对，流经送风口116的制冷气流可以对电解除氧装置200进行降温，减少或避免电解除氧装置200及其周围部件因温度过高而发生意外，因此，本发明的冰箱10具备优异的安全性能。
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。
