在描述一些实施例时，可能使用了“耦接”和“连接”及其衍伸的表达。例如，描述一些实施例时可能使用了术语“连接”以表明两个或两个以上部件彼此间有直接物理接触或电接触。又如，描述一些实施例时可能使用了术语“耦接”以表明两个或两个以上部件有直接物理接触或电接触。然而，术语“耦接”或“通信耦合(communicatively coupled)”也可能指两个或两个以上部件彼此间并无直接接触，但仍彼此协作或相互作用。这里所公开的实施例并不必然限制于本文内容。
在相关技术中，真空保鲜通过抽取存储空间中的空气，以达到降低存储空间中氧气含量的目的，从而抑制植物的呼吸作用、氧化变色变质 反应以及微生物的活动。然而，在抽取存储空间中的空气时，会使得存储空间内外产生较大的压力差，从而导致存储空间承受较大压力，因此要求制作存储空间的材料具有较高强度或要求存储空间采用复杂特殊的结构，使得应用成本升高。同时，用来抽气的真空泵会带来明显的噪音和震动，导致产品的用户体验较差。
为此，参阅图1所示，本公开一些实施例提供一种冰箱10，该冰箱10包括具有制冷室102的箱体101、制冷室箱门103、门铰链104以及保鲜装置100。
制冷室102包括冷藏室、冷冻室以及变温室等间室，每个间室有对应的制冷动力组件(例如，冷藏动力组件、冷冻动力组件及变温动力组件)来调节各间室内的温度。
制冷室箱门103通过门铰链104与箱体101连接，制冷室箱门103可以包括冷藏室箱门、冷冻室箱门以及变温室箱门三个，也可以是冷藏室箱门、冷冻室箱门以及变温室箱门三个一体成型，或者冷藏室箱门与变温室箱门一体成型。
在一些实施例中，门铰链104包括铰链座和铰链体，铰链座可以固定连接于箱体101上，铰链体一端通过铰链座的芯轴与箱体101相连，另一端与制冷室箱门103相连，使得制冷室箱门103能够自然平滑地旋转开启、关闭。图1所示的制冷室箱门103包括两扇由中间向两侧开启的箱门(从图1可观察到的表面为制冷室箱门103背离箱体101一侧的外表面)，所以箱体101两侧分别设置门铰链104。可以理解，在一些实施例中，制冷室箱门103可包括一扇整体的向一侧开启的箱门，此时在箱体101的一侧设置门铰链104即可。此外，当冰箱10具有多个制冷室箱门(例如，包括冷藏室箱门、冷冻室箱门和变温室箱门)时，在箱体101上对应每个制冷室箱门设置门铰链104即可。
保鲜装置100设置在制冷室102内，例如设置在冷藏室、冷冻室以及变温室等间室内。如图2所示，保鲜装置100包括容置盒110、抽屉120、控氧机构130。
请参考图3和图4，图3为本公开一些实施例的容置盒的装配示意图，图4为本公开一些实施例的抽屉的结构示意图。
如图3所示，容置盒110包括相连接的顶板111、两个侧板112、背板113、底板114以及框架115，其中，顶板111与底板114相对设置，两个侧板112分别位于顶板111与底板114的两侧，背板113与框架115 相对设置，由此形成具有单侧开口的容置盒110，抽屉120则可通过开口插入容置盒110内。
在一些实施例中，容置盒110内设置有导轨1141，抽屉120上设置有与导轨1141相配合的导向件122。例如，该导轨1141可沿容置盒110的深度方向设置，设置于抽屉120上的导向件122与导轨1141相配合，保证拉动抽屉120时的稳定性，便于开启和关闭抽屉120。
在一些实施例中，保鲜装置100还包括锁紧装置，该锁紧装置被配置为锁紧容置盒110和抽屉120，使得容置盒110与抽屉120之间形成密闭空间。示例地，锁紧装置可通过自吸式多段导轨来实现。设置在导向件122上的凹槽1221以及设置在自吸式多段导轨1141上与凹槽1221相对应的位置处的凸起，将抽屉120与自吸式多段导轨1141的第一段固定在一起。自吸式多段导轨1141的第一段指的是靠近容置盒110上的开口的一段。当抽屉120逐渐插入容置盒110内，多段导轨的自吸作用使得容置盒110与抽屉120锁紧以形成密闭空间，防止抽屉120松动，影响控氧效果。
在一些实施例中，框架115上还设有密封条，当抽屉120关闭时，由于锁紧装置的作用，使得抽屉120能够与密封条紧密接触，保证容置盒110内的气密性，防止外部空气进入容置盒110中。
在一些实施例中，保鲜装置100还包括主控板和开合检测机构，该主控板包括处理器(例如51单片机或者STM单片机等处理器)，被配置为控制控氧机构130进行工作。开合检测机构与主控板相连接，被配置为检测抽屉120是否开启。当开合检测机构检测到抽屉120未开启时，主控板则可以控制控氧机构130开始工作，以降低容置盒110内的氧气含量。当开合检测机构检测到抽屉120开启时，主控板则可以控制控氧机构130停止工作，以降低控氧机构130的功耗。在一些实施例中，该开合检测机构可以为光线传感器、红外传感器或磁控开关1131中的任意一种，以实现对抽屉120的开合检测。
在一些实施例中，该开合检测机构包括设置于容置盒110上的磁控开关1131(例如干簧管等)以及设置于抽屉120上的磁性件121，磁控开关1131与主控板相连接。由此，磁控开关1131与磁性件121相配合以实现检测抽屉120是否开启。示例地，磁控开关1131可设置在容置盒110的背板113上，抽屉120对应于该磁控开关1131的位置上设置有安装座，磁性件121可设置于该安装座上。
当开启抽屉120时，磁性件121远离磁控开关1131，以使得磁性件121对磁控开关1131的磁吸力减小，由此磁控开关1131可以检测到抽屉120开启，主控板根据磁控开关1131所传输的检测信号，控制控氧机构130停止工作，以降低功耗；当抽屉120关闭时，磁性件121靠近磁控开关1131，使得磁性件121对磁控开关1131的磁吸力增大，磁控开关1131则检测到抽屉120关闭，主控板根据磁控开关1131所传输的检测信号，控制控氧机构130开始工作，以降低抽屉120内的氧气含量，延长抽屉120内储存物的保鲜时间。
如图2所示，控氧机构130设置于容置盒110上，被配置为降低容置盒110内氧气的含量，从而延长抽屉120内所储存的储存物(例如食品等)的保鲜时间。在一些实施例中，如图3所示，容置盒110的背板113上开设有安装孔1132，安装孔1132周围环设有多个安装脚1133，控氧机构130通过该安装脚1133固定于容置盒110上。
如图5所示，控氧机构130包括密封框134，分别设置于密封框134两侧的阳极132和阴极131、以及排气管133。在一些实施例中，密封框134为方框结构，且形状大小与阳极132和阴极131相适配。阳极132和阴极131均为板状结构，阳极132、密封框134以及阴极131相互配合可以形成电解池。电解池被配置为容纳电解液，且电解池和由容置盒110与抽屉120所形成的空间被疏水透气的阴极131密封隔离，从而防止电解池内电解液流到容置盒110内，但可发生气体交换。阴极131靠近密封框134的一面与电解液相接触，阴极131远离密封框134的一面通过上述安装孔1132外露于容置盒110中，阳极132与阴极131相对设置，阳极132和阴极131通过导线分别与电源的正负极相连接。排气管133位于电解池的上方。排气管133一端连接电解池，另一端位于容置盒110与抽屉120所形成的空间之外的外部空间中，以实现电解池和外部空间的连通。
在一些实施例中，阳极132一般采用金属(如锌、锂、钛、合金等)制成，电解液一般为碱性溶液(例如氢氧化钠、氢氧化钾、碳酸钠、碳酸钾等)，阴极131则大多采用多孔活性炭或金属网外包裹透气催化层制成。
阴极131上包覆有透气催化层，使得阴极131在作为电解池的侧壁时，既可以防止电解池中的电解液由电解池中通过阴极131向容置盒110 内渗漏，同时也能够保证容置盒110内的氧气能够通过该透气催化层与阴极131产生反应，从而使氧气通过阴极131进入电解液内，以降低容置盒110内的氧气含量。
在一些实施例中，该透气催化层可以由催化剂以及聚四氯乙烯或者聚乙烯制成，其中聚四氯乙烯和聚乙烯具有透气不透液的功能，能够形成大量的液膜，加速氧气透过阴极进入电解液中的速率。以上仅为示例性举例，在另一些实施例中，透气催化层也可采用其他材料制成，本公开对此不做特殊限定。
由于阳极132、密封框134以及阴极131相互配合可以形成电解池，所以无需独立设置电解池，从而降低控氧机构130的制造成本。且阴极131为板状，扩大了阴极131与容置盒110内的空气的接触面积，以此可以提高控氧效率。
在一些实施例中，控氧机构130还包括壳体，电解池设置于该壳体内。例如，壳体包括相配合的前盖1352和后盖1351，前盖1352和后盖1351扣合时，可分别向阳极132和阴极131施加作用力，以使阳极132和阴极131压合于密封框134上，以保证电解池的密封性，防止电解液泄露。
此外，前盖1352对应阳极132设置，后盖1351对应于阴极131设置，且后盖1351上开设有通孔，这样既保证阴极131能够与容置盒110内的空气相接触，且还可以使后盖1351对阴极131起到保护作用，防止抽屉120或者其他物品损坏阴极131，延长了阴极131的使用寿命。示例地，后盖1351上的通孔可以为由栅格所形成的通孔，以保证容置盒110内空气向电解液内流动的流通效率。
在一些实施例中，控氧机构130还包括储水池136，储水池136设置在壳体上，储水池136位于电解池的上方，且与电解池相通。需要说明的是，在控氧机构130工作时，理论上不消耗电解液，然而因为电解池通过排气管133与外部空间相连通。因此，电解液内中的水分会被蒸发，需要定时进行补充。
通过在电解池的上方设置有储水池136，储水池136与电解池相连通，在储水池136中所储存的水可以流至电解池中以补充电解池中所蒸发的水分。同时，在电解池的上方设置储水池136，可以保证电解池中电解液的高度，进而保证阳极132和阴极131与电解液的接触面积，可以防止因为电解池内的水位减低，减少电解液与阳极132和阴极131的 接触面积而导致降低控氧机构130的工作效率。
在一些实施例中，储水池136内设置有液位传感器，该液位传感器与前述的主控板相连接。液位传感器可以用于检测储水池136内的水位，主控板根据液位传感器所传输的信号，可以判定储水池136内的水位是否过低，若过低，则可以向用户发送加水提醒，以提醒用户向储水池136内进行加水。
在一些实施例中，主控板可以通过设置在主控板上的报警器向用户进行发送加水提醒。在另一些实施例中，主控板也可以通过显示设备(例如制冷室箱门103上的显示屏等)显示加水提醒，本公开对此不做特殊限定。
以下以阳极132为金属锂为例来说明控氧机构130降低容置盒110内氧气含量的原理。控氧机构130通过放电过程将容置盒110中的氧气还原成溶解在电解液中氢氧根离子，并通过充电过程将电解液中的氢氧根离子氧化成氧气并通过排气管133将氧气排出至外部空间。
当放电时，阳极132的反应为Li→Li ++e -，金属锂以离子形式溶于电解液中，电子被供应给阴极；阴极131的反应为O 2+2H 2O+4e -→4OH -，即容置盒110内的氧气和水在阴极131表面发生反应后生成氢氧根离子。
当充电时，阳极132的反应为4OH -→O 2+2H 2O+4e -，即氢氧根离子发生反应在电解池中生成氧气、水以及电子，产生的电子供应给阴极，阴极131的反应为Li ++e -→Li，即通过阳极供应电子，锂离子在阴极表面发生反应生成金属锂；氧气可从排气管133向外部空间进行排出。
由此，通过多次的放电-充电过程，可以将由容置盒110与抽屉120所形成的空间内的氧气“转移”至电解池所形成的空间中，并最终通过排气管133转移至外部空间。由于由容置盒110与抽屉120所形成的空间内没有电解反应，因此在电解池中所产生的氧气不会返流至容置盒110内，从而达到了降低容置盒110内的氧气含量的目的，进而延长了抽屉120内所储存的储存物的保鲜时间。
且无需使用抽气装置抽取由容置盒110与抽屉120所形成的空间内的空气，而仅仅是通过控氧机构130转移该空间中的氧气，因此不会在容置盒110内外产生较大的气压差，所以不用要求制造保鲜装置100的材料具有较高强度，并且不用要求保鲜装置100采用复杂特殊的结构(如椭圆弧面、加强筋等)，从而降低了应用成本。
此外，由于保鲜装置100使用电解反应的方式将由容置盒110与抽屉120所形成的空间内的氧气转移至外部空间，而没有使用抽气装置，因而保鲜装置100也就无需使用泵或风扇等部件，因此保鲜装置100在工作时不会产生噪音和振动，提高了用户体验。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
