Description

冰箱 技术领域
本发明涉及制冷设备，特别是涉及一种冰箱。
背景技术
在日常生产生活中，通过调节合适的保藏气氛，可以适当延长物品的保存期限。不同的物品对应着不同的保藏条件，例如，通常情况下，水果、蔬菜等食材的保藏条件为低氧低温，红肉等部分肉类的保藏条件为高氧低温。
冰箱作为一种低温存储设备，可以为物品营造低温保鲜环境。随着科技的不断进步，人们期望冰箱能够具备多样化的保藏功能，既能提供低氧低温的保藏气氛，又能提供高氧低温的保藏气氛。
然而，发明人认识到，现有技术中的部分冰箱，为实现低氧和高氧保鲜功能，采用变压吸附除氧或者富氧膜除氧等方式营造低氧保鲜气氛，其主要原理为在一定压力下分离空气中的氮气和氧气，并将氮气留在或者排入低氧保鲜空间内，然后将氧气从低氧保鲜空间排出并排入高氧保鲜空间。由于需要利用增压设备实现氮氧分离，不但结构复杂，除氧过程容易产生较大噪声，而且操作繁琐，操作成本高，还对使用环境的湿度、洁净度有较高要求，否则会污染增压设备的分子筛，严重影响设备的使用寿命，导致设备的维护成本高。
发明内容
本发明的一个目的是要克服现有技术中的至少一个技术缺陷，提供一种冰箱。
本发明一个进一步的目的是要简化冰箱的结构，并使其易于营造低氧保鲜气氛和高氧保鲜气氛。
本发明另一个进一步的目的是使得冰箱同时为多个储物间室营造适当的保鲜气氛。
本发明再一个进一步的目的是要简化冰箱的导气管件的结构。
本发明又一个进一步的目的是要减少或避免冰箱的电解除氧装置在排气时泄露电解液。
特别地，本发明提供了一种冰箱，包括：箱体，其内部形成有第一储物 间室和至少一个第二储物间室；电解除氧装置，其一部分与第一储物间室气流连通，并用于通过电化学反应消耗第一储物间室内的氧气；电解除氧装置形成有用于排出氧气的排气口；以及导气管件，其进气端与排气口连通，其出气端与第二储物间室连通，并配置成将流经排气口的氧气导引至第二储物间室。
可选地，第二储物间室为多个。
可选地，导气管件的出气端为多个，且与第二储物间室一一连通。
可选地，导气管件包括：一个进气管段，从排气口朝向第二储物间室延伸，且其第一端形成进气端；多个出气管段，每一出气管段的第一端形成出气端，且每一出气管段的第二端分别连通进气管段的第二端。
可选地，导气管件还包括多通阀，其具有一个进流阀口和多个分流阀口，进流阀口连通进气管段的第二端，分流阀口与出气管段的第二端一一连通；且多通阀配置成通过受控地打开或关闭分流阀口以调节流经其的氧气的流动路径。
可选地，第一储物间室的后壁开设有镂空框；电解除氧装置设置于镂空框处，并与第一储物间室共同限定出密闭储物空间。
可选地，第二储物间室的后壁开设有与导气管件的出气端相连通的进气孔；导气管件的出气端插接于进气孔，以与进气孔密封连接。
可选地，电解除氧装置包括：壳体，其上形成有面朝第一储物间室内部的侧向开口；阴极板，设置于侧向开口处，以与壳体共同限定出用于盛装电解液的储液腔，用于通过电化学反应消耗第一储物间室内的氧气；以及阳极板，设置于储液腔内，用于通过电化学反应向阴极板提供反应物并生成氧气；且排气口设置于壳体上，并与储液腔相连通。
可选地，排气口位于壳体的顶部区段，且配置成高于储液腔内的电解液的液面最高处。
可选地，第一储物间室与第二储物间室沿冰箱的高度方向排布，或者沿冰箱的横向方向排布。
本发明的冰箱，由于电解除氧装置能够为第一储物间室营造低氧保鲜气氛，导气管件能够将电解除氧装置排出的氧气导引至第二储物间室，利用电解除氧装置和导气管件相结合，使得本发明的冰箱易于营造低氧保鲜气氛和高氧保鲜气氛，且结构简单，无需设置增压设备，有利于简化操作过程，降 低操作成本和增压设备的维护成本。
进一步地，本发明的冰箱，由于第二储物间室可以为多个，通过连通导气管件的出气端与各个第二储物间室，可使电解除氧装置排出的氧气分别到达各个第二储物间室，从而能够在第一储物间室实现低氧保鲜气氛时，使得各个第二储物间室同时实现高氧保鲜气氛，这使得冰箱同时为多个储物间室营造适当的保鲜气氛，有利于提高冰箱的气氛调节效率。
进一步地，本发明的冰箱，通过利用多通阀连接导气管件的进气管段和出气管段，可以简便地在导气管件中设置多个出气管段，这有利于简化冰箱的导气管件的结构。
更进一步地，本发明的冰箱，由于电解除氧装置的排气口位于壳体的顶部区段，且配置成高于储液腔内的电解液的液面最高处，这可以减少或避免冰箱的电解除氧装置在排气时泄露电解液。
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：
图1是根据本发明一个实施例的冰箱的示意图；

图3是图2中A处的局部放大图；
图4是图2所示的冰箱的部分结构的另一示意图；

具体实施方式
图1是根据本发明一个实施例的冰箱10的示意图。
冰箱10一般性地可包括箱体200、电解除氧装置100和导气管件300。
箱体200的内部形成有第一储物间室210和至少一个第二储物间室220。第一储物间室210和第二储物间室220的温区可以根据实际需要进行设置，例如，第一储物间室210和第二储物间室220可以分别为冷藏间室、冷冻间室和变温间室中的任意一个。第二储物间室220的数量可以根据实际需要设置为一个或多个。本实施例中，第一储物间室210可以为冷藏间室，第二储物间室220可以为冷冻间室。
电解除氧装置100的一部分与第一储物间室210气流连通，并用于通过电化学反应消耗第一储物间室210内的氧气。上述“气流连通”是指第一储物间室210内的气流可以流动至电解除氧装置100，并与电解除氧装置100的一部分接触。上述“电解除氧装置100的一部分”可以“吸收”第一储物间室210内的氧气，并将该氧气作为反应物进行电化学反应，从而实现降低第一储物间室210内部氧气的目的，使得第一储物间室210营造出低氧保鲜气氛。电解除氧装置100在消耗第一储物间室210内部氧气的同时，还会通过电化学反应生成氧气。
本实施例中，电解除氧装置100形成有用于排出氧气的排气口112。该排气口112用于排出电解除氧装置100通过电化学反应生成的氧气。
导气管件300的进气端与排气口112连通，其出气端与第二储物间室220连通，并配置成将流经排气口112的氧气导引至第二储物间室220。也就是说，导气管件300作为连通排气口112与第二储物间室220的连通部件，可以将电解除氧装置100生成的氧气排放至第二储物间室220，从而实现提高第二储物间室220内部氧气的目的，使得第二储物间室220营造出高氧保鲜气氛。
由于电解除氧装置100能够为第一储物间室210营造低氧保鲜气氛，导气管件300能够将电解除氧装置100排出的氧气导引至第二储物间室220，利用电解除氧装置100和导气管件300相结合，使得本实施例的冰箱10易于营造低氧保鲜气氛和高氧保鲜气氛，且结构简单，无需设置增压设备，有利于简化操作过程，降低操作成本和增压设备的维护成本。
图2是根据本发明一个实施例的冰箱10的部分结构的示意图，图中示出了第一储物间室210、第二储物间室220、电解除氧装置100和导气管件300。
第二储物间室220可以为多个。导气管件300的出气端为多个，且与第 二储物间室220一一连通。也就是说，导气管件300的出气端的数量与第二储物间室220的数量相同。每一出气端用于连通一第二储物间室220。
值得说明的是，图2仅以第二储物间室220为两个的情况进行示意，本领域技术人员在了解本实施例的基础上应当完全有能力针对其他数量的情况进行拓展，此处不再一一举例。
图3是图2中A处的局部放大图。
导气管件300包括一个进气管段310和多个出气管段320。进气管段310从排气口112朝向第二储物间室220延伸，且其第一端形成进气端。每一出气管段320的第一端形成出气端，且每一出气管段320的第二端分别连通进气管段310的第二端。也就是说，进气管段310的第一端连通排气口112，每一进气管段310的第一端连通一第二储物间室220，从电解除氧装置100的排气口112排出的氧气可以从进气管段310的第一端流入导气管件300，然后依次流经进气管段310的第二端、出气管段320的第二端以及出气管段320的第一端之后，再流入第二储物间室220。
由于第二储物间室220可以为多个，通过连通导气管件300的出气端与各个第二储物间室220，可使电解除氧装置100排出的氧气分别到达各个第二储物间室220，从而能够在第一储物间室210实现低氧保鲜气氛时，使得各个第二储物间室220同时实现高氧保鲜气氛，这使得冰箱10同时为多个储物间室营造适当的保鲜气氛，有利于提高冰箱10的气氛调节效率。
在一些进一步的实施例中，导气管件300还可以进一步地包括多通阀330，其具有一个进流阀口和多个分流阀口，进流阀口连通进气管段310的第二端，分流阀口与出气管段320的第二端一一连通。且多通阀330配置成通过受控地打开或关闭分流阀口以调节流经其的氧气的流动路径。例如，本实施例中，第二储物间室220为两个，多通阀330可以为三通阀，其具有一个进流阀口和两个分流阀口，每个分流阀口连通一出气管段320的第二端。也就是说，本实施例中，可以利用多通阀330连接进气管段310的第二端和出气管段320的第二端，从而使得流经进气管段310的氧气可以流入出气管段320。
通过利用多通阀330连接导气管件300的进气管段310和出气管段320，可以简便地在导气管件300中设置多个出气管段320，这有利于简化冰箱10的导气管件300的结构。
通过调节多通阀330的分流阀口的开闭状态，可以调节每个第二储物间室220的保鲜气氛，从而有利于提高冰箱10的气氛调节过程的灵活性。
图4是图2所示的冰箱10的部分结构的另一示意图，图中隐去了导气管件300和一个第二储物间室220。
本实施例中，第一储物间室210的后壁可以开设有镂空框211，该镂空框211可以为开口。电解除氧装置100可以设置于镂空框211处，并与第一储物间室210共同限定出密闭储物空间。也就是说，电解除氧装置100可以封闭镂空框211所在位置的开口，使得第一储物间室210呈密闭状态。例如，镂空框211可以为长方形开口，电解除氧装置100可以为长方体扁平盒状。
本实施例中，第一储物间室210与第二储物间室220沿冰箱10的高度方向排布。例如，第二储物间室220可以位于第一储物间室210的下方，且两个第二储物间室220可以沿冰箱10的高度方向依次排布，这可以降低导气管件的安装难度。
在一些可选的实施例中，第二储物间室220也可以位于第一储物间室210的上方。在又一些可选的实施例中，第一储物间室210与第二储物间室220还可以沿冰箱10的横向方向排布。在另一些可选的实施例中，第一储物间室210可以与一个第二储物间室220沿冰箱10的横向排布，另一个第二储物间室220可以位于第一储物间室210的上方或者下方。
第二储物间室220的后壁开设有与导气管件300的出气端相连通的进气孔222。导气管件300的出气端插接于进气孔222，以与进气孔222密封连接。也就是说，导气管件300的出气端通过插接于进气孔222，从而与第二储物间室220连通，且密封第二储物间室220的进气孔222。本实施例中，导气管件300可以从排气口112沿竖直方向向下延伸至第二储物间室220的进气孔222。
图5是根据本发明另一个实施例的冰箱10的部分结构的示意图，图中示出了第一储物间室210、第二储物间室220、电解除氧装置100和导气管件300。本实施例中，第二储物间室220可以为一个。相应地，导气管件300的出气端为一个，且导气管件300可以包括一个进气管段310、一个出气管段320和多通阀。进气管段310从排气口112朝向第二储物间室220延伸，其第一端形成进气端。出气管段320的第一端形成出气端，且出气管段320的第二端连通进气管段310的第二端。多通阀可以为二通阀，其具有一个进 流阀口和一个分流阀口，且该分流阀口连通出气管段320的第二端。
图6是根据本发明一个实施例的冰箱10的电解除氧装置100的示意图，图7是根据本发明一个实施例的冰箱10的电解除氧装置100的分解图。
电解除氧装置100可以包括壳体110、阴极板120和阳极板140。壳体110上形成有面朝第一储物间室210内部的侧向开口114。本实施例中，侧向开口114位于壳体110的前侧。
阴极板120设置于侧向开口114处，以与壳体110共同限定出用于盛装电解液的储液腔，用于通过电化学反应消耗第一储物间室210内的氧气。阴极板120与第一储物间室210的内部空间气流连通。例如，空气中的氧气可以在阴极板120处发生还原反应，即：O 2+2H 2O+4e -→4OH -。
阳极板140设置于储液腔内，用于通过电化学反应向阴极板120提供反应物(例如，电子)并生成氧气。阳极板140可以与阴极板120相互间隔地设置于储液腔内，即，阳极板140可以设置于阴极板120背朝第一储物间室的一侧。阴极板120产生的OH -可以在阳极板140处可以发生氧化反应，并生成氧气，即：4OH -→O 2+2H 2O+4e -。
电解除氧装置100的储液腔内可以盛装碱性电解液，例如0.1～8mol/L的NaOH，其浓度可以根据实际需要进行调整。
排气口112设置于壳体110上，并与储液腔相连通。本实施例中，排气口112可以位于壳体110的顶部区段，且配置成高于储液腔内的电解液的液面最高处。例如，壳体110可以为长方体扁平盒状，且沿竖直方向延伸布置。排气口112可以位于壳体110的顶壁上。竖直方向即为冰箱的高度方向。
由于电解除氧装置100的排气口112位于壳体110的顶部区段，且配置成高于储液腔内的电解液的液面最高处，这可以减少或避免冰箱10的电解除氧装置100在排气时泄露电解液。
在一些可选的实施例中，该排气口112还可以作为电解液的补液口，当电解液不充足时，可以在排气口112处向储液腔注入电解液，这可以实现排气口112的功能复用，有利于简化电解除氧装置100的结构。
在一些实施例中，冰箱10可以进一步地包括供电模组，例如电池。该供电模组靠近电解除氧装置100设置，并为电解除氧装置100提供电源。阳极板140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。阴极板120上具有从壳体110内穿出并与外部电源负极连接的阴极供 电端子152b。
在一些实施例中，电解除氧装置100还可以进一步地包括分隔件130和固定组件150。
分隔件130设置于储液腔内，并位于阴极板120与阳极板140之间，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，以分隔阴极板120与阳极板140，防止电解除氧装置100短路。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，阴极板120贴靠于分隔件130背离凸起部132的一侧，以在阴极板120与阳极板140形成预设间隙，进而将阴极板120与阳极板140分隔开。
固定组件150可以设置于阴极板120的外侧，配置成将阴极板120固定于壳体110的侧向开口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。
图8是图7所示的电解除氧装置100中支撑件154的示意图，图9是图8中B处的局部放大图。金属边框152贴靠于阴极板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和阴极板120固定于开口处。本实施例中，金属边框152与阴极板120直接接触，金属边框152可以起到压紧阴极板120的作用，并且金属边框152上还可以设置有阴极板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压紧阴极板120。
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。
阳极板140的材质可以为镍，但不限于此。
阴极板120可以由内至外地依次设置有催化层、第一防水透气层、集流层和第二防水透气层构成。其中，“外”“内”等方向性词语是相对于壳体110的实际使用状态而言的，相对于阴极板120的其他结构而言，催化层可以位于阴极板120的最内侧，以便于与储液腔内的电解液接触。
催化层可以采用金属催化剂，其中，金属可以为贵金属或稀有金属，例如可以选自由铂、金、银、锰和铷构成的物质组中。金属催化剂颗粒可以附着在乙炔黑颗粒上。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从而与催化层接触。集流层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。并且由于阴极板120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120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。
本发明的冰箱10，由于电解除氧装置100能够为第一储物间室210营造低氧保鲜气氛，导气管件300能够将电解除氧装置100排出的氧气导引至第二储物间室220，利用电解除氧装置100和导气管件300相结合，使得本发明的冰箱10易于营造低氧保鲜气氛和高氧保鲜气氛，且结构简单，无需设置增压设备，有利于简化操作过程，降低操作成本和增压设备的维护成本。
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。
