具体实施方式
现将详细参考本申请的实施例，其一个或多个示例在附图中示出。提供的各个实施例旨在解释本申请，而非限制本申请。事实上，在不脱离本申请的范围或精神的情况下对本申请进行各种修改和变化对于本领域的技术人员来说是显而易见的。例如，图示或描述为一个实施例的一部分的特征可以与另一个实施例一起使用以产生再另外的实施例。因此，本申请旨在涵盖所附权利要求书及其等同物范围内的此类修改和变化。
下面参照图1至图6来描述本申请实施例的冷藏冷冻装置10。其中，“内”“外”“上”“下”“顶”“底”“横向”“水平”“竖直”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指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申请的限制。为便于示意装置的结构，本申请的部分附图采用透视的形式进行示意。
在本实施例的描述中，术语“第一”、“第二”等仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”等特征可以明示或者隐含地包括至少一个该特征，也即包括一个或者更多个该特征。需要理解的是，术语“多个”的含义是至少两个，例如两个，三个等。除非另有明确具体的限定。当某个特征“包括或者包含”某个或某些其涵盖的特征时，除非另外特别地描述，这指示不排除其它特征和可以进一步包括其它特征。
在本实施例的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“一个示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个 或多个实施例或示例中以合适的方式结合。
图1是根据本申请一个实施例的冷藏冷冻装置10的示意性结构图。图2是图1所示的冷藏冷冻装置10的另一视角的示意性结构图，为便于示意冷藏冷冻装置10的内部构造，图中隐去了部分箱体100。本申请实施例的冷藏冷冻装置10可以为冰箱，也可以为冷柜、冷冻柜或者冷藏柜等具备低温储存功能的制冷设备。
本申请实施例的冷藏冷冻装置10一般性地可包括箱体100和储物盒500。
其中，箱体100的内部限定出储物间室122。储物间室122可以为冷藏间室、冷冻间室或者变温间室，当然也可以为深冷间室或者任意其他间室。优选地，本实施例的储物间室122为冷藏间室。
储物盒500设置于储物间室122内。储物盒500的内部空间可切换地用于储物或者储液。即，储物盒500的内部空间兼具储物功能和储液功能。当需利用储物盒500储存液体时，可以向储物盒500充入液体；当需利用储物盒500储存物体时，可以排净液体。
通过在储物间室122内设置储物盒500，并使储物盒500的内部空间可切换地用于储物或储液，可使冷藏冷冻装置10的储物盒500兼具储物功能和储液功能，以避免因布置专门的储液容器而压缩装置的有效容积。
在一些可选的实施例中，储物盒500开设有出液口511，用于允许其内部空间所储存的液体流出。出液口511设置于储物盒500的底部区段，例如可以设置于储物盒500的底壁上或者侧壁的底部。
通过在储物盒500的底部区段开设出液口511，可通过简单的方式改造储物盒500，以允许其内部空间所储存的液体流出，使其在执行储液功能时自动输出液体。
在一些可选的实施例中，冷藏冷冻装置10还包括第一保鲜容器600和氧气处理装置300。其中，第一保鲜容器600设置于储物间室122内。
氧气处理装置300具有壳体320和电极对，壳体320内限定用于盛装电解液的电化学反应仓，电极对设置于电化学反应仓，并用于通过电化学反应将第一保鲜容器600内的氧气转移至电化学反应仓，从而降低第一保鲜容器600内的氧气含量。
在一些可选的实施例中，壳体320具有连通电化学反应仓的补液口322。补液口322连通出液口511，以允许自出液口511流出的液体流入电化学反应仓。本实施例中，电化学反应在电解液中进行，随着电化学反应的进行，电化学反应仓内的电解液不断减少。
当在储物间室122内设置第一保鲜容器600，并利用氧气处理装置300消耗第一保鲜容器600内的氧气时，利用出液口511连通电化学反应仓，储物盒500所储存的液体可以源源不断地输送至电化学反应仓，作为电化学反应的物质基础，从而使氧气处理装置300持续性地调节贫氧气氛。
在一个示例中，储物盒500设置于第一保鲜容器600的上方。氧气处理装置300设置于第一保鲜容器600的后侧。
当将储物盒500设置于第一保鲜容器600的上方，并将氧气处理装置300设置于第一保鲜容器600的后侧时，可缩短储物盒500与氧气处理装置300之间的液体输送路径，提高补液效率。并且由于出液口511高于电化学反应仓，如此一来，储物盒500内的液体可以在重力作用下自动流入电化学反应仓，而无需借助动力装置。
当然，在另一些示例中，储物盒500也可以变换为低于电化学反应仓或与电化学反应仓相平。此时，可以在液体输送路径上安装泵，以在泵的作用下驱使储物盒500内的液体流入电化学反应仓；或者可以利用虹吸原理，使储物盒500内的液体流入电化学反应仓。
储物盒500内所盛装的液体可以为水；或者也可以为电解液，其浓度可以低于电化学反应仓所盛装的电解液，或与电化学反应仓所盛装的电解液一致。
在一些可选的实施例中，冷藏冷冻装置10还可以进一步地包括至少一个第二保鲜容器700，设置于储物间室122内，并与储物盒500沿横向并排设置。储物盒500的容积可以小于第二保鲜容器700的容积。也就是说，储物盒500可以为具有较小容积的容器。这样一来，当储物盒500执行储液功能时，第二保鲜容器700可以提供充足的储物空间。
储物间室122可以为冷藏间室。第二保鲜容器700可以为两个，分别为用于提供干燥储物气氛的干区容器和用于提供湿润储物气氛的湿区容器。两个第二保鲜容器700之间限定出用于安装储物盒500的安装空 间。也即，储物盒500设置于两个第二保鲜容器700之间。干区容器的顶壁上设置有密封盖720。湿区容器的顶壁上设置有保湿模块710。
通过在两个第二保鲜容器700之间预留安装空间，并将储物盒500设置于安装空间内，可在不改变储物间室122的布局结构的前提下将兼具储物功能和储液功能的多功能储物盒500嵌设其中。并且由于冷藏间室的温度较高，将储物盒500设置在冷藏间室内，可使储物盒500所储存的液体保持较高的流动性，减少或避免结冰。
当然，储物间室122内的布局方式并不限于以上举例。在一个示例中，第二保鲜容器700也可以设置为一个。储物盒500可以设置在第二保鲜容器700的横向一侧。
储物盒500的顶壁上开设有取物口514。取物口514可以作为用户实施取放物品动作的窗口，或者作为向储物盒500注入液体的窗口。
冷藏冷冻装置10还包括液质调节模块，设置于出液口511与补液口322之间的流路上，用于调节流向补液口322的液体成分。其中，出液口511与补液口322之间的流路包括出液口511和补液口322这两个端点部位以及两个端点部位之间的液体输送路径。在一个示例中，液质调节模块也可以设置于储物盒500的内部空间。
液质调节模块可以向流经的液体释放粒子，例如电化学反应仓所盛装的电解液中所含有的酸性粒子或者碱性粒子，得到含有加速电化学反应功能的功能性液体；和/或液质调节模块可以基于过滤原理滤除流经的液体中的杂质粒子，例如，钙、镁离子等等，得到净化液体，从而起到调节液质的作用。
在一个示例中，液质调节模块可拆卸地设置于出液口511处，且包括过滤芯，用于过滤流经液体中的杂质，以向电化学反应仓提供净化液体。在一个进一步的示例中，过滤芯可以采用本领域技术人员所习知的过滤结构。由于液质调节模块可拆卸地设置于出液口511处，因此，可由用户或维修人员定期更换，以持续稳定地发挥液质调节功能。
采用上述结构，利用液质调节模块调节流向补液口322的液体成分，可以保证流向补液口322的液体符合电化学反应的要求，且减少或避免液体输送路径发生堵塞。
在一些可选的实施例中，冷藏冷冻装置10还包括补液管路420和单 向阀。其中，补液管路420连接于出液口511与补液口322之间，以将流出出液口511的液体导引至补液口322。
出液口511可以为形成于储物盒500上并向外隆起的中空柱状接口。补液口322可以为形成于壳体320上并向外隆起的另一中空柱状接口。出液口511可以插接于补液管路420的第一端口内，补液口322可以插接于补液管路420的第二端口内，以实现连接。
单向阀设置于补液管路420上，以允许来自出液口511的液体单向通过，保证流经补液管路420的液体的单向流动。
在另一些可选的实施例中，冷藏冷冻装置10可以进一步地包括流量调节阀，设置于补液管路420上，用于调节流经补液管路420的液体流量，以保证补液效率，且避免补液过程对电化学反应仓产生冲击力。
在又一些可选的实施例中，冷藏冷冻装置10可以进一步地包括流量计，设置于补液管路420上，用于计量流向补液口322的液量。流量计的计量结果可以输送至冷藏冷冻装置10的人机交互界面，以向用户呈现，方便用户评估氧气处理装置300的使用寿命。人机交互界面可以为显示屏，或者可以为与冷藏冷冻装置10数据连接的终端界面。
在一些可选的实施例中，所述第一保鲜容器600的背部开设有换气口610。
图3是根据本申请一个实施例的氧气处理装置300的示意性结构图。图4是图3所示的氧气处理装置300的示意性分解图。
所述壳体320开设有侧向开口321。例如壳体320可以呈扁平的长方体形状。壳体320的侧向开口321与换气口610相对。侧向开口321可以设置在壳体320的任意面上，例如顶面、底面或者侧面。在一个示例中，侧向开口321可以设置在壳体320的面积最大的面上。
所述电极对包括阴极板330和阳极板340。其中，阴极板330设置于所述侧向开口321处以与所述壳体320共同限定出用于盛装电解液的所述电化学反应仓并封闭所述换气口610，且用于通过电化学反应消耗所述第一保鲜容器600内的氧气。空气中的氧气可以在阴极板330处发生还原反应，即：O2+2H2O+4e-→4OH-。
阳极板340与所述阴极板330相互间隔地设置于所述电化学反应仓内，并用于通过电化学反应向所述阴极板330提供反应物并生成氧气， 以将所述第一保鲜容器600内的氧气转移至所述电化学反应仓。阴极板330产生的OH-可以在阳极板340处发生氧化反应，并生成氧气，即：4OH-→O2+2H2O+4e-。
以上关于阴极板330和阳极板340的电化学反应的举例仅仅是示意性的，在了解上述实施例的基础上，本领域技术人员应当易于变换电化学反应的类型，或者针对适用于其他电化学反应类型的氧气处理装置300的结构进行拓展，这些变换和拓展均应落入本申请的保护范围。
在一些可选的实施例中，第一保鲜容器600的壁上形成有连通其内部空间的换气口610以及通向换气口610的滑道622。
图5是图2所示的冷藏冷冻装置10的示意性分解图。图6是图5中A处的局部放大图。换气口610可以为形成于第一保鲜容器600的任意壁上的开口。滑道622可以形成于第一保鲜容器600的外表面，以供氧气处理装置300在其上滑动。滑道622通向换气口610是指，滑道622自远离换气口610的位置朝向换气口610所在的位置延伸，使得沿滑道622滑动的氧气处理装置300可以滑动至换气口610处，并遮蔽换气口610。本实施例的滑道622用于限定氧气处理装置300的滑动路径，其可以为滑槽622a或者滑轨，只要能够允许氧气处理装置300沿其滑动即可。
氧气处理装置300沿滑道622可滑动地设置，以滑至遮蔽换气口610的位置，从而与第一保鲜容器600的内部空间气流连通，以通过电化学反应消耗第一保鲜容器600内的氧气。本实施例的氧气处理装置300可以沿滑道622往复滑动，从而与第一保鲜容器600实现可拆卸地连接。例如，当需要拆卸氧气处理装置300时，可使氧气处理装置300沿滑道622滑离换气口610。
通过在第一保鲜容器600的壁上设置换气口610以及通向换气口610的滑道622，并使氧气处理装置300沿滑道622滑至或滑离换气口610，可以简便快捷地使氧气处理装置300与第一保鲜容器600的内部空间实现气流连通。当需使氧气处理装置300与第一保鲜容器600的内部空间之间建立气流通道时，仅需将氧气处理装置300沿滑道622滑动至换气口610，并遮蔽换气口610即可，无需增设额外的气流管路，也无需借助安装工具执行安装操作。
由于氧气处理装置300可以通过换气口610直接与第一保鲜容器600 的内部空间接触，无需借助气流管路进行气体交换，因此，经氧气处理装置300处理的气体可以直接排放至第一保鲜容器600的内部空间。基于本申请的方案，有利于缩短氧气处理装置300与第一保鲜容器600的内部空间之间的气流路径，提高气调效率。
冷藏冷冻装置10可以预设有气调保鲜模式，并且可以在启动气调保鲜模式时，使氧气处理装置300工作，例如，向氧气处理装置300提供电源，使其在电解电压的作用下进行电化学反应，从而调节第一保鲜容器600内的氧气含量。
在一些可选的实施例中，氧气处理装置300的壳体320的外壁上形成有向外凸出的外凸卡爪328，滑道622限定出供外凸卡爪328伸入其中从而实现可滑动地配合的滑槽622a。外凸卡爪328卡入滑槽622a内，并且沿滑槽622a滑动，使得氧气处理装置300沿滑道622可滑动地设置。
通过在壳体320的外壁上设置外凸卡爪328，并利用外凸卡爪328与滑槽622a进行配合，安装者可以徒手将氧气处理装置300装配至换气口610处。氧气处理装置300沿滑道622滑动时，其壳体320始终与第一保鲜容器600的外壁相互贴靠，因此当氧气处理装置300滑动至换气口610处时，壳体320可以与换气口610的外周相互贴靠从而遮蔽换气口610，使第一保鲜容器600的储物空间呈密闭状态，避免漏气。
在一些可选的实施例中，第一保鲜容器600的壁上形成有朝向其储物空间向内凹陷以容纳壳体320的凹窝620。换气口610位于凹窝620的内端壁上。且滑道622位于凹窝620的内侧壁上。壳体320在外凸卡爪328伸入滑槽622a时与凹窝620的内端壁相贴靠。凹窝620的内端壁与凹窝620的开口相对。凹窝620的内侧壁连接于内端壁的外周与凹窝620的开口边沿之间。
通过在凹窝620的内侧壁上设置滑道622，并在凹窝620的内端壁上开设换气口610，且使壳体320在外凸卡爪328伸入滑槽622a时与凹窝620的内端壁相贴靠，在滑道622的引导下，氧气处理装置300可以在凹窝620的内部滑动，且在滑动过程中始终贴靠于凹窝620的内端壁，当氧气处理装置300滑动至换气口610的外侧时，即可遮蔽换气口610，并且可以严丝合缝地密封换气口610。
通过在第一保鲜容器600上设置凹窝620结构，并使氧气处理装置 300沿凹窝620的内侧壁所限定的滑道622滑动，在凹窝620的保护作用下，氧气处理装置300的滑动过程不会受外界环境干扰。由于氧气处理装置300始终位于凹窝620的内部，因此，当其滑至换气口610处后，几乎不会与外部物体发生接触，这有利于提高氧气处理装置300与第一保鲜容器600之间的装配结构稳定性。
在一些可选的实施例中，凹窝620的内端壁上形成有环绕换气口610并向内凹陷的环状凹槽624。冷藏冷冻装置10还可以进一步地包括环状密封圈650，设置于环状凹槽624内，并与滑至换气口610的氧气处理装置300相互挤压，以实现密封。密封圈650可以为橡胶密封圈650。
通过在换气口610的周向外侧设置环状密封圈650，并使环状密封圈650与滑至换气口610的氧气处理装置300相互挤压，可使氧气处理装置300与换气口610的外周实现严丝合缝地接合，从而防止漏气。
在一些可选的示例中，凹窝620的内侧壁垂直于凹窝620的内端壁。滑道622为两个，且位于凹窝620的两个相对的内侧壁上。外凸卡爪328为两个，且相应设置于壳体320的两个相对的外壁上。
例如，凹窝620可以形成于第一保鲜容器600的背壁上。第一保鲜容器600的背壁可以包括沿竖直方向延伸的竖直板段以及垂直于竖直板段并沿水平方向向外伸展且沿竖直方向相互间隔设置的两个水平板段。两个水平板段之间限定出凹窝620。竖直板段形成凹窝620的内端面。凹窝620的内侧面是指两个水平板段相对的板面。各个水平板段可以分别自第一保鲜容器600的背壁的横向一端沿水平方向延伸至横向另一端。
两个水平板段相对的板面上可以分别具有平行且间隔设置的第一凸棱和第二凸棱，并且第一凸棱和第二凸棱沿水平板段的宽度方向平行且间隔设置。第一凸棱和第二凸棱之间限定出供外凸卡爪328插入其中的滑槽622a。
在一些可选的实施例中，冷藏冷冻装置10还可以进一步地包括第一定位模块660和第二定位模块670，沿氧气处理装置300的滑动方向相互间隔地设置于换气口610的两侧，并夹持壳体320的两端，以将氧气处理装置300定位在换气口610处。
采用第一定位模块660和第二定位模块670将氧气处理装置300定 位在换气口610处，可以减少或避免氧气处理装置300相对于换气口610发生位移，从而保证第一保鲜容器600的储物空间的密封效果以及氧气处理装置300针对第一保鲜容器600内部空间的氧气调节效果。
第一定位模块660邻近滑道622的末端，且自凹窝620的内端壁向外伸展，例如可以伸展至滑道622的上方，以阻挡氧气处理装置300沿滑道622继续滑动。第二定位模块670为定位销，且滑道622所在的凹窝620的内侧壁上开设有贯穿其厚度方向的通孔626，以供第二定位模块670插入其中以实现固定。
在一个示例中，定位销与氧气处理装置300相贴靠的端面可以为平面。采用平面状的端面与氧气处理装置300相贴靠，可以增大二者之间的接触面积，提高定位结构的稳定性。定位销背离氧气处理装置300的端面可以为弧状曲面，例如该弧状曲面的截断面可以为半圆形状。通过在定位销上设置弧状曲面，可以减小定位销在插入通孔626时所受的摩擦阻力，从而降低装配难度。
在另一些示例中，储物盒500可以与氧气处理装置300一体成型设置，或与氧气处理装置300固定连接，例如通过插接结构实现连接固定，这可使储物盒500与氧气处理装置300实现模块化，省略二者之间的管路结构。
在一些进一步的实施例中，壳体320还具有连通电化学反应仓的排气孔323，用于排出电化学反应仓的氧气。
箱体100可包括第一内胆120。以上实施例中，储物间室122可以为冷藏间室，其由第一内胆120限定出。在一个示例中，箱体100还包括第二内胆150，其内侧限定出另一储物间室152，例如变温间室或者冷冻间室。冷藏冷冻装置10还具有预埋于发泡层内的输氧管路440，其连通排气孔323与另一储物间室152。例如，输氧管路440的一端可以直接或间接地连通排气孔323，另一端可以直接地连通另一储物间室152，从而连通排气孔323与另一储物间室152，以向另一储物间室152输送氧气，营造高氧保鲜气氛，提升冷藏冷冻装置10的保鲜性能。
在一些可选的实施例中，壳体320内部可以设置有隔板，其沿横向延伸，以在壳体320的内部空间分隔出电化学反应仓以及位于电化学反应仓上方并连通电化学反应仓的排气仓。排气仓可以收集电化学反应仓 排出的氧气，并经排气孔323排出。排气孔323可以设置于排气仓的侧壁上。开设有排气孔323的排气仓的侧壁远离第一保鲜容器600设置，以防第一保鲜容器600遮蔽排气孔323。补液口322可以设置于排气仓的侧壁上。开设有补液口322的排气仓的侧壁远离第一保鲜容器600设置，以防第一保鲜容器600遮蔽补液口322。
侧向开口321可以为多个，相应地，阴极板330和阳极板340分别为多个。每个侧向开口321处分别设置有一个阴极板330，从而形成多个电化学反应仓。每一电化学反应仓分别设置有一个阴极板330和一个阳极板340，从而形成一个除氧单元。多个除氧单元之间可以串联或并联连接。
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申请的多个示例性实施例，但是，在不脱离本申请精神和范围的情况下，仍可根据本申请公开的内容直接确定或推导出符合本申请原理的许多其他变型或修改。因此，本申请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。
