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是根据本发明一个实施例的冰箱的氧气处理装置和分离仓的示意性结构图；
图3是根据本发明另一实施例的分离仓200的示意性结构图；
图4是根据本发明一个实施例的冰箱的氧气处理装置的示意性结构图；
图5是图4所示的冰箱的氧气处理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。本实施例的冰箱10为具备低温存储功能的电器设备，既包括狭义的冰箱，也包括冷柜、储藏柜以及其他冷藏冷冻装置。
冰箱10一般性地可包括箱体500、氧气处理装置100以及导气组件400。本实施例中，氧气处理装置100在进行电化学反应消耗第一储物区510的氧气的同时，还会生成氧气。为避免生成的氧气进行无规则扩散，充分发挥氧气处理装置100针对氧气的处理能力，实现氧气处理装置100的功能复用， 提高冰箱10的气氛调节效果，发明人针对冰箱10的内部结构进行了改进。
箱体500的内部形成有第一储物区510和第二储物区520。每个储物区可以分别作为独立的储物间室。除了第一储物区510和第二储物区520之外，箱体500的内部还可以根据实际需要设置其他储物区。
氧气处理装置100的至少一部分与第一储物区510气流连通，并用于通过电化学反应消耗第一储物区510的氧气且生成氧气。且氧气处理装置100形成有排气口112，用于排出生成的氧气。本实施例的第一储物区510用于形成低氧保鲜空间。氧气处理装置100的至少一部分与第一储物区510气流连通是指，第一储物区510内的气体可以流动至氧气处理装置100，并与氧气处理装置100的至少一部分接触，从而使得气体中的氧气可以作为反应物被电化学反应所消耗。
导气组件400具有进气端、第一出气端和第二出气端，其中，进气端用于与排气口112连通，第一出气端与第二储物区520连通，并用于将流出排气口112的氧气导引至第二储物区520，第二出气端用于与箱体500的外部环境连通，并用于将流出排气口112的氧气导引至外部环境。也就是说，导气组件400用于对流出排气口112的氧气进行导引，使氧气选择性地进入第二储物区520或者流向外部环境。
本实施例的第二储物区520可以用于形成高氧保鲜空间。当氧气处理装置100排出的氧气进入第二储物区520时，可使第二储物区520内的氧气浓度升高，营造出高氧保鲜气氛，使得第二储物区520适于存储肉类和菌菇类等物品。当第二储物区520不需要输入氧气时，例如，当第二储物区520内存放的物品种类发生变化且不需要营造高氧保鲜气氛时，或者当第二储物区520内的氧气浓度达到预设要求时，可使氧气处理装置100排出的氧气流至第二出气端，并排至外部环境。
本发明的冰箱10，通过增设导气组件400，并使导气组件400构造成既能将氧气处理装置100生成的氧气导引至第二储物区520，又能将氧气处理装置100生成的氧气导引至箱体500的外部环境，可使冰箱10合理地处理氧气处理装置100生成的氧气，从而防止生成的氧气因无规则扩散而破坏低氧保鲜气氛。
由于导气组件400能将氧气处理装置100生成的氧气导引至第二储物区520，使得第二储物区520内的氧气浓度升高，因此，本发明的冰箱10能够 利用氧气处理装置100同时营造低氧保鲜气氛和高氧保鲜气氛，这有利于简化冰箱10结构、提升冰箱10性能。
在一些可选的实施例中，导气组件400包括导气开关阀410、第一出气导管420和第二出气导管430。其中，导气开关阀410用于调节流经其的氧气的流动路径。
导气开关阀410具有导气进气接口、第一导气阀口和第二导气阀口，其中，导气进气接口用于连接至排气口112，并作为进气端。导气进气接口作为导气开关阀410的进气接口。第一导气阀口和第二导气阀口分别作为导气开关阀410的出气阀口。
第一出气导管420和第二出气导管430分别与第一导气阀口和第二导气阀口对应连通，例如，第一出气导管420与第一导气阀口对应连通，使得流经第一导气阀口的氧气可以流经第一出气导管420，第二出气导管430与第二导气阀口对应连通，使得流经第二导气阀口的氧气可以流经第二出气导管430。
第一出气导管420自第一导气阀口延伸至第二储物区520，且其末端作为第一出气端，第二出气导管430自第二导气阀口延伸至箱体500的外部环境，且其末端作为第二出气端。即，第一出气导管420将流经其的氧气导引至第二储物区520，第二出气导管430将流经其的氧气导引至外部环境。
导气开关阀410为电磁三通阀，并用于受控地开闭第一导气阀口和第二导气阀口，从而调节流经其的氧气的流动路径。例如，当打开第一导气阀口且关闭第二导气阀口时，导气开关阀410可将流经其的氧气导引至第一出气导管420，当打开第二导气阀口且关闭第一导气阀口时，导气开关阀410可将流经其的氧气导引至第二出气导管430。
通过对导气开关阀410的阀口开闭状态进行控制，可以调节氧气的流动路径，使得氧气选择性地流入第二储物区520或者流至外部环境，这有利于提高冰箱10气氛调节过程的灵活性。
例如，第一储物区510和第二储物区520可以分别安装有氧气浓度传感器，冰箱10可以根据氧气浓度传感器的检测值确定导气开关阀410的阀口的开闭状态。
例如，当第一储物区510的氧气浓度高于预设要求且第二储物区520的氧气浓度低于预设要求时，氧气处理装置进行电化学反应时，导气开关阀可 以打开第一导气阀口且关闭第二导气阀口。随着电化学反应的进行，若第一储物区510的氧气浓度先达到预设要求，而第二储物区520的氧气浓度暂未达到预设要求，则可以继续进行电化学反应且暂不调整导气开关阀410的阀口的开闭状态，待第二储物区520的氧气浓度达到预设要求时，再停止电化学反应且关闭导气开关阀410的全部阀口。随着电化学反应的进行，若第二储物区520的氧气浓度先达到预设要求，而第一储物区510的氧气浓度暂未达到预设要求，则可以继续进行电化学反应且关闭导气开关阀410的第一导气阀口并打开第二导气阀口，待第一储物区510的氧气浓度达到预设要求时，再停止电化学反应且关闭导气开关阀410的全部阀口。
又如，当第一储物区510的氧气浓度高于预设要求而第二储物区520的氧气浓度达到预设要求时，氧气处理装置进行电化学反应时，导气开关阀可以打开第二导气阀口且关闭第一导气阀口。待第一储物区510的氧气浓度达到预设要求时，再停止电化学反应且关闭导气开关阀410的全部阀口。
再如，当第二储物区520的氧气浓度低于预设要求而第一储物区510的氧气浓度达到预设要求时，氧气处理装置进行电化学反应时，导气开关阀可以打开第一导气阀口且关闭第二导气阀口。待第二储物区520的氧气浓度达到预设要求时，再停止电化学反应且关闭导气开关阀410的全部阀口。
在一些可选的实施例中，第二储物区520上开设有进气孔，以供第一出气导管420***其中，使得第一出气端连通第二储物区520。箱体500上开设有开口，以供第二出气导管430***其中，使得第二出气端连通外部环境。
在一些进一步的实施例中，第二储物区520位于第一储物区510的上方。且氧气处理装置100设置在第一储物区510的后侧。进气孔可以开设在第二储物区520的后壁上，开口可以开设在箱体500的后壁上。如此设置，可使氧气处理装置和导气组件400分别安装在箱体500内的后部，这可以提高冰箱10整体的美观度，减少或避免各个部件对用户的取放物品过程产生干扰，且缩短氧气的流动路径。在另一些可选的实施例中，氧气处理装置100可以设置在第一储物区510内，并位于一储物区510的后部。
在一些可选的实施例中，冰箱10还可以进一步地包括排气开关阀，连接至排气口112，用于受控地启动或关闭，从而通断排气口112与导气进气接口之间的通路。
例如，排气开关阀为电磁二通阀，且其具有排气进气接口和排气阀口， 排气进气接口连接至排气口112，排气阀口用于连通导气进气接口，且排气开关阀用于通过受控地启动或关闭来开闭排气阀口，从而通断排气口112与导气进气接口之间的通路。
通过在排气口112处安装排气开关阀，即便氧气处理装置100发生位移或倾斜，氧气处理装置100内的液体也无法从排气口112溢出，因此，本实施例的氧气处理装置100具备较高的安全性，能有效防止发生漏液问题，从而有利于延长装置的使用寿命，增强保鲜效果。
由于排气开关阀能够彻底地切断排气口112与氧气处理装置100外部空间的通路，因此，无论是氧气处理装置100自身发生倾斜或者倒置现象，或者是安装有氧气处理装置100的冰箱10发生倾斜或者倒置现象，电解液均不会从排气口112溢出，从而彻底解决了装置的漏液隐患。
在一些可选的实施例中，冰箱10还包括分离仓200，其具有进气口220和出气口240，其中进气口220与排气口112相连通。本实施例中，进气口220用于允许流出排气口112的氧气流入分离仓200内。
分离仓200的内部形成弧状气流通道，用于成使流经其的氧气沿曲面流动，从而使氧气所携带的液体分离。流经弧状气流通道的气体通过沿曲线流动，可以形成涡流，并实现气液分离。本实施例提供了一种具备气液分离功能的冰箱10，被分离出的液体滞留在分离仓200内，从而能够减少或避免冰箱10因氧气排放而导致环境污染。
出气口240与导气进气接口相连通，用于将分离液体后的氧气排至导气进气接口。
图2是根据本发明一个实施例的冰箱10的氧气处理装置100和分离仓200的示意性结构图，图中的箭头方向示出气流流动方向。在一些可选的实施例中，分离仓200为中空筒状或者中空球状，以限定出弧状气流通道。分离仓200的内壁形成上述弧状气流通道。在气体流入分离仓200之后，会受到自身重力的作用以及分离仓200内壁的阻挡和引导，以离心向下倾斜旋转的方式流动，形成涡流，在此过程中，氧气所携带的液体会因与分离仓200的内壁碰撞而附着在内壁上，或因流速降低而被分离出来，不断富集并最终滑落至分离仓200的底部，去除液体的清洁气体则可以通过分离仓200的出气口240排出，以此完成气液分离。
由于弧状气流通道可以采用中空筒状或者中空球状的分离仓200限定出 来，仅需要使排气口112连通中空筒状壳体110或者中空球状壳体110，即可进行气液分离，因此，本实施例的冰箱10具备结构精巧、制造成本低的优点。
进气口220位于分离仓200的顶部区段或者中部区段，并与排气口112相连通，例如可以通过连通管300进行间接地连通。出气口240与进气口220间隔设置，配置成排出流经分离仓200的气体。优选地，出气口240可以与进气口220相对设置于同一高度，或者可以高于进气口220设置，这可以减少或避免未经气液分离的气体直接从出气口240排出。例如，出气口240与进气口220可以相对设置，并位于分离仓200的中上部，进气口220可以靠近分离仓200的前端设置，出气口240可以靠近分离仓200的后端设置。
图3是根据本发明另一实施例的分离仓200的示意性结构图。在一些可选的实施例中，分离仓200内可以设置有导气管260，与出气口240相连通，并向下延伸至分离仓200的底部区段，且与分离仓200的底壁之间形成间隙。例如，导气管260可以呈倒L型，或者可以为直管。分离出液体的气体可以流经导气管260，并在导气管260的导引下流向出气口240。图3中箭头示出气流流动方向。
利用导气管260连通出气口240与分离仓200的内部空间，可以进一步防止附着在分离仓200内壁的液体随气体流出，并且由于该导气管260限定出自下而上的气流排放路径，因此该导气管260也能够起到一定的气液分离作用，从而进一步优化分离仓200的气液分离效果。
在一些可选的实施例中，分离仓200内还可以设置有隔板，或者填充有填料，以利用隔板或者填料进行气液分离。在另一些可选的实施例中，分离仓200进行气液分离的方式还可以变换为旋风式。
图4是根据本发明一个实施例的冰箱10的氧气处理装置100的示意性结构图。氧气处理装置100具有壳体110，其内部形成用于进行电化学反应的反应仓111，排气口112开设在壳体110上。排气口112处还可以连接有排气管160。
壳体110上还开设有连通反应仓111的回液口118。且分离仓200的底部开设有出液口210，连通回液口118，以使分离仓200分离出的液体回流至氧气处理装置100内。
也就是说，因气液分离而被滞留在分离仓200内的液体可以依次流经出 液口210以及回液口118，并重新返回反应仓111内，这使得本实施例的冰箱10具备资源回收功能，这有利于提高氧气处理装置10的资源利用率。
在一些进一步的实施例中，冰箱10还包括回液开关阀(未示出)，设置于回液口118处，配置成受控地启动或关闭，从而打开或封闭回液口118。也就是说，通过对回液开关阀的启闭状态进行控制，可以开闭回液口118，进而通断分离仓200与反应仓111之间的液体流路。
在一些实施例中，回液开关阀可以为二通电磁阀，且具有进液接口和出液阀口，进液接口连接至出液口210，出液阀口连接至回液口118，且回液开关阀配置成受控地启动或关闭，以开闭出液阀口。
回液开关阀配置成在排气开关阀封闭排气口112之前受控地启动，且配置成与排气开关阀同时关闭。例如，回液开关阀可以在氧气处理装置100结束电化学反应之后(间隔1～10min，例如5min)受控地启动，并维持设定时长(例如1～10min)，然后再使排气开关阀和回液开关阀同时地受控关闭，以封闭排气口112和回液口118。如此设置，可以确保反应仓111内的气体全部排出，且能避免液体回收过程对气液分离过程产生干扰。
排气开关阀还配置成在氧气处理装置100开始进行电化学反应之前受控地启动。例如，在确定需要对第一储物区510或者第二储物区520的氧气进行处理时，先启动排气开关阀，并在确保出气阀口为打开状态的情况下，再使氧气处理装置100开始进行电化学反应。
需要说明的是，对于电磁阀而言，通过对其通电状态进行控制，即可调节启闭状态，例如，电磁阀不通电时为关闭状态，通电时则为启动状态。在了解本实施例的基础上，本领域技术人员应当易于获知电磁阀的结构和位置，因此，图中未做标示。
图5是图4所示的冰箱的氧气处理装置100的示意性分解图。在一些实施例中，氧气处理装置100还可以进一步地包括阳极部140、阴极部120、分隔件130和固定组件150。
壳体110上开设有安装口114。阴极部120设置于安装口114处，以与壳体110共同限定出用于盛装电解液的反应仓111。
例如，壳体110大致可以呈扁平的长方体状，并且壳体110的其中一个侧壁可以打开，以形成上述安装口114。阳极部140与阴极部120相互间隔地设置于反应仓111内。
在通电情况下，阴极部120用于通过电化学反应消耗氧气。例如，空气中的氧气可以在阴极部120处发生还原反应，即：O2+2H2O+4e-→4OH-。阴极部120产生的OH-可以在阳极部140处发生氧化反应，并生成氧气，即：4OH-→O2+2H2O+4e-。氧气可以通过壳体110上的排气口112排出。阳极部140可以为阳极电极，例如镍网或者钛网，阴极部可以为阴极电极，例如含有银和二氧化锰的催化膜。
分隔件130设置于反应仓111内，并位于阴极部120与阳极部140之间，用于分隔阴极部120与阳极部140，防止发生短路。具体地，分隔件130上朝向阳极部140的一侧形成有多个凸起132，凸起132抵触于阳极部140上，阴极部120贴靠于分隔件130背离凸起132的一侧，以在阴极部120与阳极部140形成预设间隙，进而将阴极部120与阳极部140分隔开。
固定组件150可以设置于阴极部120的外侧，配置成将阴极部120固定于壳体110的安装口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贴靠于阴极部120的外侧。金属边框152与阴极部120直接接触，可以起到压紧阴极部120的作用，并且金属边框152上还可以设置有阴极部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压紧阴极部120。阳极部140上形成有阳极供电端子142。以与供电电源相连。
本发明的冰箱10，通过增设导气组件400，并使导气组件400构造成既能将氧气处理装置100生成的氧气导引至第二储物区520，又能将氧气处理装置100生成的氧气导引至箱体500的外部环境，可使冰箱10合理地处理氧气处理装置100生成的氧气，从而防止生成的氧气因无规则扩散而破坏低氧保鲜气氛。
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。
