请参见图1和图2,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的分解图,其中隐去了箱体10。本发明提供一种冰箱1,其一般性地可以包括箱体10和门体20。
箱体10可以包括外壳和多个内胆40,外壳位于整体冰箱1的最外侧,以保护整个冰箱1。多个内胆40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),以降低内胆40向外散热。每个内胆40可以限定出向前敞开的储物空间,并且储物空间可以被配置成冷藏室、冷冻室、变温室等等,具体的储物空间的数量和功能可以根据预先的需求进行配置。
门体20可动地设置于内胆40的前方,以开闭内胆40的储物空间,例如门体20可以通过铰接的方式设置箱体10前部的一侧,通过枢转的方式开闭储物空间。
请参见图1和图3,图3是根据本发明另一个实施例的冰箱1的分解图,其中隐去了箱体10。在一些实施例中,该冰箱1还可以包括抽屉组件30,抽屉组件30可以设置于内胆40内,用户可以通过抽拉的方式开闭抽屉组件30,以拿取其内的食物。
具体地,该抽屉组件30还可以包括筒体32和抽屉本体34,筒体32可以直接固定安装于其中一个内胆40内,抽屉本体34的内部限定出储物空间,并且抽屉本体34通过滑轨组件36可抽拉地连接于筒体32内。
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100,该电解除氧装置100可以设置于内胆40或者抽屉组件30上,通过电解反应分离流经其上的空气中的氧气,并将氮气留在内胆40或抽屉本体34的储物空间内,实现对食物的保鲜储存。
请参见图2,例如,该电解除氧装置100可以设置于内胆40的外部后方。内胆40的后壁上可以开设多个将其内的空气导出的通风孔42,电解除氧装置100可以固定设置于通风孔42处,以将内胆40内的空气吸入其内,并将氧气从空气中分离出来排出内胆40,这样降低了内胆40内的空气含氧量,提高了食物的保鲜性能。
请参见图3,又例如,该电解除氧装置100还可以设置于抽屉组件30的外部后方。抽屉组件30的筒体32的后壁上可以开设多个通风孔42,电解除氧装置100可以设置于通风孔42处。对应地,抽屉本体34的后壁与通风孔42相对的位置处形成凹陷部342,以便于抽屉本体34的空气从通风孔42导出。
当然,本领域技术人员在知晓本实施例的技术方案后还可以将该电解除氧装置100设置于内胆40或者抽屉组件30的其他位置。例如,内胆40的侧壁、底壁或者顶壁上,抽屉组件30的内筒顶壁或前壁等位置,在此不一一列举。
请参见图4至图6,图4是根据本发明一个实施例的电解除氧装置100的示意图,图5是根据本发明一个实施例的电解除氧装置100中阴极复合板120的分解图,图6是根据本发明一个实施例的电解除氧装置100的分解图。
在一些实施例中,该电解除氧装置100还可以包括壳体110和阴极复合板120。壳体110上具有开口,阴极复合板120设置于该开口处,以电解流经其上的空气中的氧气,以生成负离子,并允许负离子透过阴极复合板进入储液腔内的电解液。并且阴极复合板120还可以与壳体110共同限定出用于盛装电解液的储液腔。也即,本实施例的阴极复合板120可以直接作为壳体110的其中一个壁面,用于密封储液腔。
请参见图4,在一些具体的实施例中,壳体110为中空结构,并且其上开设有用于加注电解液的补液口112和用于排出氧气的排气口114。
请参见图5,阴极复合板120可以由从内向外依次设置的催化层122、第一防水透气层124、导电层126和第二防水透气层128构成,所述“由从内向外”可以理解成由壳体110的内部向外部的方向。催化层122可以采用贵金属或稀有金属催化剂,例如金属铂、金属金、金属银、金属锰或金属铷等。第一防水透气层124和第二防水透气层128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124和第二防水透气层128进入储液腔。导电层126可以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。
如背景技术部分所述,现有技术的除氧装置仅采用防水透气膜对电解室进行密封,不仅难以经受电解液的腐蚀,而且容易泄露,实用性差。
为了克服上述现有技术中的缺陷,本实施例的电解除氧装置100采用将阴极复合板120整体地作为壳体110的一个壁面,以与壳体110共同限定出储液腔,利用阴极复合板120对储液腔进行密封。并且由于阴极复合板120本身具有一定的强度,完全能够满足储液腔的密封强度需求,另外阴极复合板120采用两层防水透气层(即第一防水透气层124和第二防水透气层128)也能够有效地防止由于电解液腐蚀引起的泄漏。
请参见图2至图6,在一些实施例中,壳体110还可以被设置成为扁平状,开口开设于壳体110较宽的侧面。由于阴极复合板120覆盖于开口处,因此开口越大,阴极复合板120的面积越大,这样阴极复合板120与空气的接触面积越大,提高了电解除氧装置100的电解效率。此外,壳体110设置 成扁平状还能够缩短电解除氧装置100的宽度,减少其占用厚度,节省空间。
请参见图6,在一些实施例中,电解除氧装置100还可以包括阳极板140,阳极板140还可以采用耐蚀性和还原性强的材料制成,例如金属泡沫镍、镍网等。
阳极板140可以与阴极复合板120间隔地设置于储液腔内,其上具有从壳体110内穿出并与外部电源正极连接的阳极供电端子142。在电解时,阳极板140用于将电解液内的负离子还原为氧气,并排出储液腔,以将流经电解除氧装置100的空气中的氧气分离出。
在工作时,抽屉组件30或者内胆40的储物空间中的空气通过通风孔42与位于壳体110开口处的阴极复合板120接触,空气中的氧气在阴极复合板120发生还原反应,即:O
2+2H
2O+4e
-→4OH
-;O
2+H
2O+2e
-→HO
2+OH
-;随着阴极复合板120上的还原反应进行,电解出的负离子OH
-能够透过阴极复合板120进入储液腔内的电解液内,并在阳极板140上发生氧化反应,即:4OH
-→O
2+2H
2O+4e
-;HO
2+OH
-→O
2+H
2O+2e
-,最终在阳极板140上生成氧气,并将生成的氧气从壳体110上的排气口114排出,实现将空气中的氧气分离出,进而降低了储物空间的含氧量,保证了食物的保鲜性。
在一些实施例中,阳极板140与阴极复合板120还可以平行设置,以提高其相对面积,促进电解反应正向进行。
此外,发明人通过多次试验发现:将阳极板140与阴极复合板120之间的距离设置成5mm至10mm范围内(例如5mm、7mm或者10mm等),既能够避免因阳极板140与阴极复合板120的间距过大而导致反应效率低,又能够避免因间距过小而导致阳极板140产生的氧气无法及时排出,影响反应进程,其技术效果已经在试制产品中得到验证。
请参见图6,在一些实施例中,该电解除氧装置100还可以包括分隔件130,分隔件130设置于储液腔内,并位于阴极复合板120与阳极板140之间,配置成分隔阴极复合板120与阳极板140,以防止电解除氧装置100短路。
由于阳极板140与阴极复合板120在电解时极性相反,并且两者之间的间距较小,因此阳极板140与阴极复合板120有可能在吸引力的作用下靠近,甚至直接接触,这既改变了原始设计的阴阳极间距参数,又有可能出现短路情况。因此,本实施例的电解除氧装置100采用在阴极复合板120与阳极板 140之间设置分隔件130,以避免出现上述情况,既保证了电解除氧装置100的除氧效率,又提高了电解除氧装置100的安全性。
请参见图6,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,阴极复合板120贴靠于分隔件130背离凸起部132的一侧,以在阴极复合板120与阳极板140之间形成预设间隙,进而将阴极复合板120与阳极板140分隔开。
请参见图6至图9,图7是图6的A处放大图,图8是根据本发明一个实施例的电解除氧装置100中支撑件154的示意图,图9是图8中B处放大图。
在一些实施例中,该电解除氧装置100还可以包括固定组件150,固定组件150设置于阴极复合板120的外侧,配置成将阴极复合板120固定于开口处。
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贴靠于阴极复合板120的外侧,并且金属边框152朝外凸起形成有围立部152a。支撑件154设置于金属边框152的外侧,并且其具有外圈1542和位于外圈1542内部的内圈1544,外圈1542与壳体110固定连接,内圈1544的内侧形成有插接槽1544a,围立部152a伸入至插接槽1544a内,以将金属边框152和阴极复合板120固定于开口处。
在本实施例中,金属边框152与阴极复合板120直接接触,金属边框152可以起到压紧阴极复合板120的作用,并且金属边框152上还可以设置有阴极复合板120的阴极供电端子152b,以与外部电源相连。
围立部152a形成于金属边框152并朝向外部延伸,以插进支撑件154的内圈1544插接槽1544a内,进而对金属边框152进行定位。又由于支撑件154的外圈1542与壳体110固定连接,因此当金属边框152的围立部152a插进支撑件154的插接槽1544a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压紧阴极复合板120。
请参见图8,在一些实施例中,支撑件154的外圈1542与内圈1544之间以及内圈1544的内部还形成有加强筋1546,用于固定连接支撑件154的外圈1542与内圈1544,并且对支撑件154的外圈1542与内圈1544进行定型,防止其受外力变形。
在组装本实施例的电解除氧装置100时,首先可以将阳极板140固定设 置于壳体110内;再将分隔件130具有凸起部132的一侧压紧在阳极板140上;将阴极复合板120压紧在分隔件130的另一侧,以防止阴极复合板120和阳极板140接触;之后将金属边框152压紧在阴极复合板120的外侧,将支撑件154覆盖在金属边框152的外侧,使其外圈1542与壳体110固定连接,并且使金属边框152的围立部152a伸入至插接槽1544a内,完成定位和固定,然后在支撑件154的外圈1542与内圈1544之间设置有粘黏剂(例如聚氨酯PU胶、环氧树脂AB胶等),对阴极复合板120和外壳之间的区域打胶,实现最终封装;最后通过壳体110上的补液口112加注电解液,完成组装。
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。
