Description

冰箱及其电解除氧装置 技术领域
本发明涉及冷藏冷冻装置，特别是涉及一种冰箱及其电解除氧装置。
背景技术
现有技术中出现了一种具备降低冰箱储物间室内氧气含量的冰箱，其工作原理是利用电解的方式将储物间室内的氧气分离并且排出，以实现除氧保鲜的目的。
为了防止在运输、安装等过程中电解液流出污染环境，现有技术出现了一种具有防漏功能的除氧装置。具体地，利用在储液箱的顶部设置环绕导管，环绕导管在储液箱的任意外周都具有凸出部分，以实现防漏。
然而，上述现有技术中的防漏方案也具有一定的缺陷。环绕导管的行程过长，难以拆卸，不利于进行加注电解液的操作，一旦除氧装置翻转后导管内必然会残留部分液体，难以完全排出，影响透气性，甚至在排气压力过大时液体从导管内直接喷出，发生事故。
发明内容
本发明的一个目的旨在克服现有技术中的至少一个缺陷，提供一种冰箱及其电解除氧装置。
本发明一个进一步的目的是要延缓从排气注液口流出电解液的速度。
本发明另一个进一步的目的是避免排气管内积液。
特别地，本发明提供了一种电解除氧装置，用于通过电化学反应分离冰箱的储物间室空气中的氧气，该电解除氧装置包括：壳体，其内部限定出用于盛装电解液的电解腔，并且壳体的顶部开设有排气注液口；和排气管，其一端与排气注液口相连通，并且排气管沿壳体回转弯折多次呈弯折状，以延缓电解液倾倒出电解腔的流速。
可选地，排气管包括：第一直管区段，其第一端与排气注液口相连通，并向上延伸；第一弯管区段，其第一端形成于第一直管区段的第二端，并向下弯折延伸；第二直管区段，其第一端形成于第一弯管区段的第二端，并向下延伸；第二弯管区段，其第一端形成于第二直管区段的第二端，并向上弯折延伸；第三直管区段，其第一端形成于第二弯管区段的第二端，并向上延 伸。
可选地，该电解除氧装置还包括：盖帽，其包括盖帽本体和形成于盖帽本体一侧的管路支架，盖帽本体可拆卸地连接于排气注液口上，并且盖帽本体上形成有与排气注液口相连通的进气口，管路支架上具有一贯穿孔；第一直管区段的第一端与进气口相连通，且第三直管区段穿设于贯穿孔。
可选地，排气管的各区段的管径相等，且小于进气口的管径。
可选地，排气管的部分区段凸出于壳体的至少一个侧周壁。
可选地，壳体具有向一侧敞开的进氧口；且电解除氧装置还包括：阴极板，设置于进氧口处，以与壳体共同限定出电解腔，配置成通过电化学反应消耗储物间室内部氧气；阳极板，设置于电解腔内，配置成通过电化学反应向阴极板提供反应物。
可选地，壳体为扁平状；且进氧口开设于壳体较宽的侧面。
可选地，排气注液口设置于壳体靠近阳极板的一侧。
可选地，阴极板包括沿壳体由内向外方向依次设置的催化层、第一防水透气层、导电层和第二防水透气层。
特别地，本发明还提供了一种冰箱，包括上述任一项的电解除氧装置。
本发明的电解除氧装置，由于排气管设置于排气注液口处，且排气管回转弯折多次呈弯折状，因此当电解除氧装置发生异常情况(如倾倒、倒立等)时，电解腔内的电解液在经过排气注液口流出时先要经过排气管，而弯折状的排气管延长和弯曲了电解液的流出路径，延缓了电解液流出流速。并且电解液在流出过程中还受到了排气管内壁对其的沿程阻力，使得向外流出的电解液流速下降，甚至可能在大气压的作用下使电解液根本无法从排气管中排出，实现了防漏作用。
进一步地，本发明的电解除氧装置，排气管经过两次180°弯折，在第一直管区段和第二直管区段之间、第二直管区段和第三直管区段之间分别采用第一弯管区段和第二弯管区段进行连接，以实现排气管的回转弯折。经过两次弯折的排气管既能够防漏，又不易储存残余电解液。
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：

具体实施方式
请参见图1至图3，图1是根据本发明一个实施例的冰箱1的示意图，图2是根据本发明一个实施例的冰箱1的局部截面图，图3是根据本发明另外一个实施例的冰箱1的分解图，其隐藏了外壳。本发明提供一种冰箱1，其一般性地可包括箱体100和门体200。
箱体100可以包括外壳和储物容器，外壳位于整体冰箱1的最外侧，以保护整个冰箱1。储物容器的数量可以为多个，且一般性可包括抽屉组件400和多个内胆300。储物容器被外壳包裹，并且与外壳之间的空间中填充有保温材料(形成发泡层)，以降低储物容器向外散热。
请参见图2，每个内胆300可以限定出向前敞开的储物间室310，并且多个储物间室310可以被配置成冷藏室、冷冻室或变温室等等，具体的储物间室310的数量和功能可以根据预先的需求进行配置。门体200可动地设置于内胆300的前方，以开闭内胆300的储物间室310，例如门体200可以通过铰接的方式设置箱体100前部的一侧，通过枢转的方式开闭储物空间。
请参见图3，抽屉组件400可以包括抽屉本体410和筒体420，抽屉本体410的内部限定出储物间室310，并且抽屉本体410通过滑轨组件430可抽拉地连接于筒体420内，用户可以通过抽拉的方式开闭抽屉本体410，以 拿取其内的食物。
请参见图2和图3，在一些实施例中，该冰箱1还可以包括电解除氧装置500，电解除氧装置500可以用于降低内胆300或者抽屉本体410的储物间室310内氧气含量。
储物容器开设有用于将其内空气导出的气流口320，电解除氧装置500可以设置于储物容器的外部，并直接或间接地与储物容器的气流口320相连，以使得储物间室310内的空气能够通过气流口320到达电解除氧装置500上，并在电解除氧装置500通过电化学反应消耗储物间室310导出的气流中的氧气，以达到降低储物间室310内氧气含量的目的。
在一些具体的实施例中，电解除氧装置500可以直接地安装于储物容器的外部，并且使其阴极贴靠于气流口320上。例如，内胆300上开设气流口320，电解除氧装置500直接地安装在内胆300的外部，且与气流口320相连通，实现将储物间室310的空气导入电解除氧装置500，以实现分离空气中的氧气。
又例如，请参见图3，抽屉组件400的筒体420的后壁上可以开设多个气流口320，电解除氧装置500固定连接于筒体420的后壁外部，对应地，抽屉本体410的后壁与气流口320相对的位置处形成凹陷部440，以便于抽屉本体410的空气从通风孔导出，同样能够实现分离出储物间室310内空气中的氧气。
请参见图2，在另外一些具体的实施例中，电解除氧装置500还可以间接地连接于储物容器的气流口320。例如，电解除氧装置500可以通过连通组件600与储物容器的气流口320相连，连通组件600设置于箱体100内，并且形成有用于连通储物间室310与箱体100的外部环境的连通通道601，连通通道601的第一端K1形成有用于安装电解除氧装置500的安装框(图中未示出)，第二端K2与储物容器的气流口320相连，这样可以通过连通组件600将储物容器的空气引导至电解除氧装置500。此外，连通组件600还可以将其第一端K1延伸向箱体100的外部，使其当电解除氧装置500安装于安装框时，其至少部分暴露于冰箱1外，以便将氧气从顺畅地排至外部环境中。
请参见图4和图5，图4是根据本发明一个实施例的冰箱1中电解除氧装置500的示意图，图5是根据本发明一个实施例的冰箱1中电解除氧装置 500的分解图。在一些实施例中，该电解除氧装置500还可以包括壳体501、阴极板510和阳极板520。
壳体501其内限定出用于盛装电解液的电解腔。电解液可以为碱性电解液，例如1mol/L的NaOH，其浓度可以根据实际需要进行调整。壳体501的其中一个壁面向一侧敞开形成进氧口512。
阴极板510可以设置于进氧口512处，以与壳体501共同限定出储液腔，并且阴极板510面朝气流口320，用于在电解电压的作用下通过电化学反应消耗储物间室310内部氧气，并生成负离子。例如，空气中的氧气可以在阴极板510处发生还原反应，即：O 2+2H 2O+4e -→4OH -。
阳极板520设置于电解腔内且位于阴极板510背朝气流口320的一侧，用于通过电化学反应向阴极板510提供反应物(例如电子)，以将空气中的氧气分离出。例如，阴极板510产生的OH -可以在阳极板520处可以发生氧化反应，并生成氧气，以实现将空气中的氧气分离出，即：4OH -→O 2+2H 2O+4e -。
在一些实施例中，阳极板520可以由镍材料制成。阴极板510由内至外地依次设置有催化层、第一防水透气层、导电层和第二防水透气层构成。其中“内”是指壳体501的内部，即电解腔，“外”是指壳体501的外部，即阴极板510背离电解腔的一侧。
催化层可以采用金属/碳催化剂，金属可以为贵金属或稀有金属，例如选自由金属铂、金属金、金属银、金属锰和金属铷构成的物质组中。碳可以为炭黑。第一防水透气层和第二防水透气层可以为防水透气膜，以使得电解液无法从储液腔渗出，而空气可以透过第一防水透气层和第二防水透气层进入储液腔。导电层制作成耐腐金属集流网，例如金属镍、金属钛等，以使其不仅具备较佳的导电性、防腐性和支撑强度，并且由于阴极板510本身具有一定的强度，完全可以能够满足储液腔的密封强度需求，另外阴极板510采用两层防水透气层也能够有效地防止由于电解液腐蚀引起的泄漏。
请参见图5至图8，图6是图5中的A处放大图，图7是根据本发明一个实施例的电解除氧装置500中支撑件544的示意图，图8是图7中B处放大图。在一些实施例中，该电解除氧装置500还可以包括分隔件530和固定组件540。
分隔件530可以设置于阴极板510与阳极板520之间，且其上形成有多 个朝向阳极板520的凸起部532，在组装后，凸起部532抵触与阳极板520上，阴极板510抵靠于分隔件530背离凸起部532的一侧，以防止阴极板510与阳极板520接触，从而避免了该电解除氧装置500短路。
固定组件540可以包括金属边框542和支撑件544。金属边框542贴靠于阴极板510的外侧，金属边框542朝外凸起形成有围立部5422；支撑件544设置于金属边框542的外侧，且其具有内圈5442和外圈5444，内圈5442上形成插接槽5442a，外圈5444与壳体501固定连接。在组装后，金属边框542抵压在阴极板510上，并且围立部5422伸入插接槽5442a，以对金属边框542和支撑件544进行定位，外圈5444与壳体501固定连接，直接将金属边框542和阴极板510固定在壳体501上。
在一些实施例中，支撑件544的外圈5444与内圈5442之间以及内圈5442的内部还形成有加强筋5446，用于固定连接支撑件544的外圈5444与内圈5442，并且对支撑件544的外圈5444与内圈5442进行定型，防止其受外力变形。
请参见图9和图10，图9是根据本发明一个进一步实施例的冰箱1中电解除氧装置500的分解图，其示出了壳体501、盖帽560和排气管550的位置关系，图10是图9中C处放大图。在一些实施例中，该电解除氧装置500还可以包括排气管550。
壳体501的顶部开设有排气注液口502，该排气注液口502不仅可以用于将在阳极板520上生成的氧气排出，而且还可以供用户或者维护人员向电解腔内加注电解液，无须将电解除氧装置500整体拆卸，安全且方便。
排气管550的一端与排气注液口502相连通，并且排气管550回转弯折多次呈弯折状，以延缓电解液倾倒出电解腔的流速。排气管550的弯折次数可以为两次、三次或更多，本实施例对排气管550的弯折次数不作特殊限定。
由于排气管550设置于排气注液口502处，且排气管550回转弯折多次呈弯折状，因此当电解除氧装置500发生异常情况(如倾倒、倒立等)时，电解腔内的电解液在经过排气注液口502流出时先要经过排气管550，而弯折状的排气管550延长和弯曲了电解液的流出路径，延缓了电解液流出时间。并且电解液在流出过程中还受到了排气管550内壁对其的沿程阻力，使得向外流出的电解液流速下降，甚至可能在大气压的作用下使电解液根本无法从排气管550中排出，实现了防漏作用。
如背景技术部分所述，现有技术的防漏方案由于导管的行程过长，不仅难以拆卸进行补液，而且容易储存残留电解液，影响透气性。为了克服上述现有技术的缺陷，本实施例中的电解除氧装置500中，排气管550采用回转弯折的方式延长和弯曲了电解液的流出路径，有效地解决了防漏问题，并且排气采用回转的弯折的方式不会在壳体501的任意周壁上凸出，使得排气管550占用空间较小，容易拆卸，便于维护人员加注电解液。
请参见图10，在一些进一步的实施例中，排气管550可以包括第一直管区段551、第一弯管区段552、第二直管区段553、第二弯管区段554和第三直管区段555。第一直管区段551的第一端与排气注液口502相连通，并向上延伸，第一弯管区段552的第一端形成于第一直管区段551的第二端，并向下弯折延伸，第二直管区段553的第一端形成于第一弯管区段552的第二端，并向下延伸，第二弯管区段554的第一端形成于第二直管区段553的第二端，并向上弯折延伸，第三直管区段555的第一端形成于第二弯管区段554的第二端，并向上延伸。
也即是，本实施例的排气管550经过两次180°弯折，在第一直管区段551和第二直管区段553之间、第二直管区段553和第三直管区段555之间分别采用第一弯管区段552和第二弯管区段554进行连接，以实现排气管550的回转弯折。
发明人通过大量试验发现：经过一次弯折的排气管550仍然可能发生漏液现象，而经过三次以上弯折的排气管550在电解除氧装置500倾倒并扶正后管内仍可能留有积液，而经过两次弯折的排气管550既能够防漏，又不易储存残余电解液。
在本实施例中，排气管550的一端可以与排气注液口502直接连接，也可以与排气注液口502间接地连通。具体地，当排气管550与排气注液口502间接地连通时，该电解除氧装置500还可以包括盖帽560，盖帽560包括盖帽本体561和形成于盖帽本体561一侧的管路支架562，盖帽本体561可拆卸地连接于排气注液口502上，并且盖帽本体561上形成有与排气注液口502相连通的进气口563，管路支架562上具有一贯穿孔564。第一直管区段551的第一端与进气口563相连通，且第三直管区段555穿设于贯穿孔564。
盖帽本体561可以采用卡扣、螺纹连接等可拆卸方式安装在排气注液口502上，并且盖帽本体561上的进气口563也可以采用卡扣、过盈配合或气 路快接头等方式与排气管550的一端密闭连接。
管路支架562设置于盖帽本体561的一侧，当排气管550的一端与进气口563连接后，排气管550的第二直管区段553先向下延伸，然后第三直管区段555再向上延伸，并穿过贯穿孔564进行限位和固定。也即是，盖帽560可以在排气管550的两端对其进行固定，并且能够使其保持两次弯折状态。
在电解除氧装置500使用一段时间后，用户或维护人员可以直接拆卸掉盖帽560，实现移除排气管550并暴露出排气注液口502，便于加注电解液，在加注完成后直接加将盖帽560恢复原位即可，操作简单。
在一些实施例中，排气管550的各区段的管径相等，且小于进气口563的管径，以便将排气管550套设在进气口563上。另外，由于排气管550的管径小于进气口563的管径，由于在相同外界条件下，一般液体的粘性较气体大，因此对于管径较小的排气管550，液体受到的阻力较大，而气体受到的阻力较小，这样能够不仅有效地延缓了电解液倾倒时在排气管550内的流速，而且对正常使用状态下氧气的排放影响较小。
在一些实施例中，排气管550的部分区段凸出于壳体501的至少一个侧周壁。例如排气管550的部分区段可以凸出于壳体501上设置阴极板510的侧面、壳体501背离阴极板510的侧面、或者其他侧面中的至少一个。这样当电解除氧装置500倾倒后且排气管550凸出于壳体501区段处于上方时，保证排气管550具有高于壳体501的区段，避免电解液从排气管550内排出。
在一些实施例中，壳体501为扁平状，且进氧口512开设于壳体501较宽的侧面。由于阴极板510覆盖于进氧口512处，因此进氧口512越大，阴极板510的面积越大，这样阴极板510与空气的接触面积越大，提高了电解除氧装置500的电解效率。此外，壳体501设置成扁平状还能够缩短电解除氧装置500的宽度，减少其占用厚度，节省空间。
在一些实施例中，排气注液口502可以设置壳体501靠近阳极板520的一侧。即，相对于阴极板510而言，排气注液口502更加靠近阳极板520，排气注液口502可以设置于壳体501的顶部后侧，这可以缩短氧气的排放路径，便于快速排出阳极板520产生的氧气。
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。
