本发明的描述中，除非另有明确的限定，设置、安装、连接等词语应做广义理解，所属技术领域技术人员可以结合技术方案的具体内容合理确定上述词语在本发明中的具体含义。
如图15所示，本发明第一方面的除氧模组100，用于冰箱的除氧保鲜，冰箱200可以指的是广义的制冷存储设备，例如电冰箱、电冰柜、冷藏柜等等。
参照图1、图2，本发明实施例的一种除氧模组100，包括电解液箱110和水箱130，电解液箱110用于存储电解液，在电解液箱110上设有进水口111，进水口111与电解液箱110内腔连通，水箱130上设有出水口131，出水口131设于靠近水箱130底部的位置，并且出水口131与水箱130内腔连通，出水口131与进水口111通过第一管道120连接，以通过水箱向电解液箱110补水。
可以理解的是，为实现通过出水口131与进水口111向电解液箱110补水的目的，出水口131的高度高于进水口111高度；或者，在满足水箱130的液面与进水口111的高度差大于出水品131与进水口111的高度差的条件下，也可以将出水口131的高度设置成低于进水口111高度，以通过水压将水补入电解液箱110。
在除氧模组100内部设有阴极电极和阳极电极(图中未示出)，阴极电极通过防水透气膜与空气接触，除氧模组100的工作原理是：空气中的氧气通过防水透气膜渗透进入电解液箱110，同时空气中的氮气被防水透气膜阻挡在电解液箱110外，氧气在阴极作用下与水产生电化学反应，生成氢氧根离子，同时，在阳极产生电化学反应，氢氧根离子反应生成水和氧气，从而将空气的中的氧气置换出来，并通过排气孔140排出除氧模组100外面，从而使抽屉内部氧气含量降低，进而达到保鲜作用。
由于除氧模组100在工作过程中，排出的氧气会带走部分水分，导致电解液箱110内电解液的水分逐渐减少，影响除氧模组100的正常工作，需要客户自行定期补充水分。本发明实施例的除氧模组100在使用时，由于水箱130具有预定的容量，水箱130内添加有可以满足除氧模组100较长使用周期的水，水箱130中的水可以通过第一管道120向电解液箱110补充，使电解液箱110内的液位维持在正常范围内，从而解决除氧模组补水的问题，解决除氧模组100长时间工作而出现的电解液箱110缺水的弊端。
参照图1、图2，在本发明的一些实施例中，电解液箱110上设有第一气压平衡口112，第一气压平衡口112与电解液箱110内腔的电解液面上部的空间连通，水箱130上设有第二气压平衡口132，第二气压平衡口132与水箱130中液面上部的空间连通，第一气压平衡口112与第二气压平衡口132通过第二管道150连接，以使水箱130和电解液箱110的气压保持平衡。
除氧模组100产生的气体如果不能及时地排出会产生较大的压力，会导致除氧模组100的电解膜的破坏，并且可能导致水箱130的水不能顺利流入电解液箱110，因此本实施例采用在电解液箱110和水箱130上设置气压平衡口，并通过管道将气压平衡口连接，实现水箱130和电解液箱110之间的气压平衡，防止除氧模组100的电解膜被破坏，保护除氧模组100，同时也便于水箱130的水能顺利进入电解液箱110。
如图1、图2所示，在一些实施例中，第一气压平衡口112位于进水口111上方，且位于电解液面上部，第二气压平衡口132位于出水口131的上方，且位于水箱液面上部，以保证水箱130和电解液箱110内腔的液面之上的空间连通，实现水箱130和电解液箱110之间的气压平衡。
可以理解的是，在一些实施例中，第一气压平衡口112可以设置在电解液面之下的电解液箱110上，电解液箱110内部通过管道与第一气压平衡口112连接，并将管道的出口设于电解液面之上；同样的，第二气压平衡口132可以设置在液面之下的水箱130上，水箱130内部再通过管道与第二气压平衡口132连接，并将管道的出口高于水箱130液面之上，同样可以保证水箱130液面之上的空间和电解液箱110内腔的液面之上的空间连通，实现水箱130和电解液箱110之间的气压平衡。
在一些实施例，第一管道120和第二管道150采用软质管道，采用软管连接，方便水箱130和除氧模组100的分离，便于在电解液箱110或水箱130损坏后，可以单独更换电解液箱110或水箱130，减少维修成本。
参照图1、图2，在一些实施例中，在水箱130上设有加水口(图中未示出)，加水口上安装有可以封堵加水口的密封结构，以便于生产时加装水，以及便于在水箱130中的水使用完毕后客户自行向水箱130中加水。
如图1和图2所示，在一些实施例中，密封结构可以是设置在加水口上的水箱盖133，水箱盖133与加水口通过螺纹连接，水箱盖133里面装有防漏垫片(图中未示出)，以防止水分蒸发或者泄露。
在一些实施例中，水箱盖133与加水口还可采用公知的连接方式，如扣合连接等等，在此不作详述。
可以理解的是，密封结构还可以是通过管道与加水口连接的阀门，阀门可采用单向阀、截止阀等等。
参照图3、图4、图5，在一些实施例中，电解液箱110上设有氧气排气孔140，除氧模组100将空气中的氧气置换出来后可通过排气孔140排出，以使电解液箱110内的气压维持在正常状态。排气孔140上设有防倾倒泄漏结构300，当在运输过程中冰箱200出现倾倒时，可防止除氧模组100的电解液泄漏，避免电解液泄漏对冰箱200的腐蚀。
参照图6至图12，在一些实施例中，防倾倒泄漏结构300包括排气通道310、浮球320及止挡部330，排气通道310沿竖直方向设置在电解液箱110内，排气通道310的一端与排气孔140连接，另一端与电解液箱110连通；浮球320设置在排气通道310内，浮球320与排气通道310之间具有间隙，浮球320的直径大于排气孔140的内径，浮球320能够封堵排气孔140；止挡部330设置在排气通道310与电解液箱110连通的一端，以防止浮球320从排气通道310内掉落。
可以理解的是，在一些实施例中，为满足除氧模组110在倾倒时浮球320能封堵排气孔140的要求，需要考虑浮球重力与电解液对浮球的浮力及电解液对浮球的表面张力之间的关系，实验证明，同时满足浮球的密度小于1.3×10 3kg/m 3、浮球半径大于4mm、与电解液不发生反应等条件的材料，均可作为浮球的材质，如PP材质等等。
如图11、图12所示，在一些实施例中，止挡部330为沿排气通道310径向向排气通道310轴线方向延伸的三个止挡筋，三个止挡筋均匀设置在排气通道310的内圆周上，止挡筋与排气通道310一体成型。在一些实施例中，止挡筋还可设置为一个、两个或多个，并且止挡部330还可以与排气通道310分体设置，并通过固定件固定在排气通道310上，同样能达到防止浮球从排气通道内掉落的目的。
参照图6、图7，图中所示是除氧模组在正常状态时上述实施例的防倾倒泄漏结构的结构示意图，如图所示，电解液箱110设有上盖113，排气孔140设置在上盖113上，浮球320在自身重力作用下落在止挡部330上，氧气通过浮球320与排气通道310之间的间隙排到除氧模组100外部。
参照图8、图9、图10，图中所示是除氧模组在倒置时上述实施例的防倾倒泄漏结构的结构示意图，如图所示，在运输或者搬运过程，冰箱200或者除氧模组100发生倾斜时，浮球320在自身重力及溶液压力作用下堵住排气孔140，以防止溶液泄露出模组。
参照图11、图12，在一些实施例，排气通道310的内壁轴向设置有三条排气槽311，排气槽311主要作用是在浮球320落到止挡部330时，增大气体排除通道，增大排气量；排气槽311一端与电解液箱110连通，并且，排气槽311的长度小于排气通道310的长度，以防止浮球320堵在排气孔140时，电解液从排气槽311泄露出模组。
在一些实施例中，排气槽311还可根据实际情况设置成一条、两条或多条。
参照图7、图9、图10，在一些实施例中，排气通道310和排气孔140的连接端设置成与浮球320对应接触的球面匹配的圆弧形，以防止浮球320封堵在排气孔140上时浮球320与排气孔140之 间出现缝隙，提高浮球320封堵排气孔140的可靠性。
参照图7、图9、图10，在一些实施例中，排气通道310的直径从下往上逐渐变小，以使除氧模组100在使用时浮球320能正常落在止挡部上，并且便于除氧模组100从倾倒状态恢复至正常状态时，浮球320能顺利回落至止挡部330。
可以理解的是，在一些实施例中，防倾倒泄漏结构300还可采用在排气孔140内安装防水透气膜等结构，同样可达到防止除氧模组100的电解液泄漏、避免电解液泄漏对冰箱腐蚀的目的。
参照图3，在一些实施例中，电解液箱110的顶部设有泄压阀160，泄压阀160的开启压力可根据除氧模组100的安全压力进行设置，当除氧模组100的排气孔140出现堵塞，电解液箱110内的压力达到除氧模组100的安全压力时，泄压阀160自动开启泄压，以防止除氧模组100内压力过大而损坏除氧模组100。
参照图13、图14，图13、图14为本发明的第二方面实施例的保鲜装置400，图中所示的保鲜装置400包括框架410、抽屉420以及上述任一实施例提供的除氧模组100。
如图所示，框架410设置有容纳空间411，框架410的一侧设置有开口412，框架410的壁上设有透气孔413(如图2所示)，透气孔413与容纳空间411连通；抽屉420能通过开口412进入并收容于容纳空间411中，以与框架410配合形成密闭的存储空间；除氧模组100的电解液箱110设置于框架410的透气孔413处，除氧模组100上的防水透气膜与透气孔413相对，电解液箱110与框架410之间设置有密封条，以防止保鲜装置400外的空气进入除氧模组100，保鲜装置400在工作时，容纳空间411内的氧气可通过框架410上的透气孔413进入除氧模组100，通过除氧模组100将氧气置换出来，并通过除氧模组100上的排气孔140排出除氧模组100外，从而使抽屉420内部氧气含量降低，进而达到保鲜作用。
本发明实施例提出的保鲜装置400，包括有上述实施例中任一项提供的除氧模组100，因此，水箱130中的水可以通过第一管道120向电解液箱110补充，使电解液箱110内的液位维持在正常范围内，从而解决除氧模组补水的问题，解决除氧模组100长时间工作而出现的电解液箱110缺水的弊端。
参照图13，在一些实施例中，框架410包括内框架414和外框架415，外框架415设置在内框架414上，其中，容纳空间411设置在内框架414内，开口412设置在内框架414的一侧，透气孔413设置在内框架414远离开口412的侧壁，水箱130设置在内框架414的上侧壁；电解液箱110设置在内框架414和外框架415之间，从而使保鲜装置400结构紧凑，提升保鲜装置的有效利用空间。
在一些实施例中，电解液箱110通过第一固定结构500可拆卸地设置在内框架414上，水箱130通过第二固定结构600可拆卸地设置在内框架414上，以便于除氧模组100和保鲜装置400的维护。
如图2、图13所示，在一些实施例中，第一固定结构500包括第一连接柱510、第一阶梯孔520和第一固定连接件(图中未示出)。
如图所示，第一连接柱510设置在内框架414的侧壁，第一连接柱510可以是与内框架414一体成型，也可以是与内框架414分体设置，与内框架414分体设置时，第一连接柱510通过固定结构如 螺钉、螺纹固定结构等等固定在内框架414上，第一连接柱510内设置有第一连接孔511；第一阶梯孔520设置在电解液箱110的对应位置，第一阶梯孔520包括不同孔径的第一大孔521和第一小孔522，第一大孔521和第一小孔522连通，第一连接柱520能够设置于第一大孔521；第一固定连接件穿过第一小孔522并与第一连接孔511螺纹连接。
可以预见的是，第一固定连接件可以是螺钉、螺栓等连接件。
如图所示，在一些实施例，第二固定结构600包括第二连接柱610、第二阶梯孔620和第二固定连接件(图中未示出)。
第二连接柱610设置在内框架414的上侧壁，可以是与内框架414一体成型，也可以是与内框架414分体设置，与内框架414分体设置时，第二连接柱610通过螺钉、螺纹固定结构等等固定在内框架414上，第二连接柱610内设置有第二连接孔611；第二阶梯孔620设置在水箱130的对应位置，第二阶梯孔620包括不同孔径的第二大孔和第二小孔(图中未示出)，第二大孔和第二小孔连通，第二连接柱610能够设置于第二大孔；第二固定连接件穿过第二小孔并与第二连接孔611螺纹连接。
可以预见的是，第二固定连接件可以是螺钉、螺栓等连接件。
可以预见的是，在第一阶梯孔520的端部设置有第一引导面523，在第二阶梯孔620的端部设置有第二引导面(图中未示出)，以方便第一连接柱510和第二连接柱610插入对应的第一阶梯孔520和第二阶梯孔620内。
电解液箱110通过上述的第一固定结构可拆卸地设置在内框架414上，水箱130通过上述的第二固定结构可拆卸地设置在内框架414上，从而提高电解液箱110与内框架414之间、水箱130与内框架414之间的连接可靠性，并且装配简单、高效、方便，减小装配难度，提高系统效率。
可以理解的是，固定结构还可直接采用螺钉或螺栓与螺纹孔配合的结构，在此不作详述。
如图13所示，在一些实施例中，开口412与抽屉420之间设置有密封条422，以保证开口412与抽屉420之间的密封性，密封条422可以设置在内框架414上，抽屉420的端盖内侧的轮廓形状同密封条422的形状相适应，密封条422可以采用改性聚氯乙烯(PVC)，硫化三元乙丙橡胶(EPDM)和热塑性三元乙丙橡胶(EPDM/PP)胶条；密封条422也可设置抽屉420的端盖421内侧，方便框架的开口412与抽屉420之间的密封。
如图2所示，在一些实施例中，透气孔413设置有多个，多个透气孔413呈阵列设置在框架的侧壁，设置多个透气孔413，可提高容纳空间411与除氧模组100之间的氧气转移的面积，提高除氧模组100的除氧效率。
可以理解的是，为使保鲜装置400实现保鲜的功能，需要向保鲜装置400的除氧模组100提供电能，因此，除氧模组100还包括有电控板170，电控板170可安装在内框架414上，电控板170与除氧模组100电连接，可通过设置保鲜装置400中氧含量参数，使电控板170控制除氧模组100开启和关闭，以将保鲜装置400中的氧含量控制在设定的范围。并且，为实现水箱130向电解液箱110的自动补水，可在第一管道120上设置电控阀，电控阀与电控板170电连接，在电解液箱110的液面达到 预定位置时，通过电控板170控制电控阀启动，向电解液箱110补水，电解液箱110的液面补充到预定位置时，电控板170控制电控阀关闭，从而使电解液箱110内的液位维持在正常范围内。
参照图15，图15为本发明的第三方面实施例的冰箱200，包括有上述实施例中任一项实施例提供的保鲜装置400，本发明提供的冰箱200采用的保鲜装置可以通过第一管道120将水箱130中的水向电解液箱110补充，使电解液箱110内的液位维持在正常范围内，从而解决除氧模组补水的问题，解决除氧模组110长时间工作而出现的电解液箱110缺水的弊端，使除氧装置100能长时间稳定工作，从而使安装在冰箱200内的保鲜装置400获得富氮贫氧环境，利于食材的保鲜。该低氧环境能有效抑制水果蔬菜呼吸作用，减少有机物质的消耗，又可以让果蔬细胞缓慢呼吸，维持细胞生命力，保持果蔬优良风味和芳香气味。还可以有效抑制好氧细菌和厌氧细菌滋生繁殖，防止微生物腐败果蔬。另外，低氧也能抑制某些酶的活性，抑制乙烯产生，延缓后熟和衰老过程，长期保持果实的营养新鲜。
当然，本发明创造并不局限于上述实施方式，熟悉本领域的技术人员在不违背本发明精神的前提下还可作出等同变形或替换，这些等同的变型或替换均包含在本申请权利要求所限定的范围内。
