Description

冷藏冷冻装置 技术领域

具体实施方式
现将详细参考本发明的实施例，其一个或多个示例在附图中示出。提供的各个实施例旨在解释本发明，而非限制本发明。事实上，在不脱离本发明的范围或精神的情况下对本发明进行各种修改和变化对于本领域的技术人员来说是显而易见的。例如，图示或描述为一个实施例的一部分的特征可以与另一个实施例一起使用以产生再另外的实施例。因此，本发明旨在涵盖所附权利要求书及其等同物范围内的此类修改和变化。

在本实施例的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“一个示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
本发明实施例提供了一种冷藏冷冻装置10。图1是根据本发明一个实施例的冷藏冷冻装置10的示意性结构图。图2是图1所示的冷藏冷冻装置10的另一视角的示意性结构图。其中，图1为前侧视角，图2为后侧视角。图3是图2所示的冷藏冷冻装置10的示意性内部结构图，图中隐去了内胆120。
冷藏冷冻装置10一般性地可包括箱体100、氧气处理装置300和储液模块500。本发明实施例的冷藏冷冻装置10可以为冰箱，也可以为冷柜、冷冻柜或者冷藏柜等具备低温储存功能的制冷设备。
箱体100具有内胆120以及形成于内胆120外侧的发泡层180，内胆120的内侧限定出储物空间122。例如，内胆120的内侧可以限定出储物间室。储物空间122可以直接指储物间室的内部空间，当然也可以 指设置于储物间室内的储物容器600的内部空间。发泡层180可以由保温隔热材料制成，例如聚氨酯泡沫等。
氧气处理装置300与储物空间122气流连通，并用于通过电化学反应来调节储物空间122的氧气含量，例如通过电化学反应消耗储物空间122的氧气从而降低储物空间122的氧气含量，或者通过电化学反应生成氧气并将生成的氧气通入储物空间122从而提高储物空间122的氧气含量。
例如，冷藏冷冻装置10可以预设有气调保鲜模式，并且可以在启动气调保鲜模式时，使氧气处理装置300工作，例如，向氧气处理装置300提供电源，使其在电解电压的作用下进行电化学反应，从而调节储物空间122的氧气含量。
储液模块500具有盒体510，其设置于发泡层180内，且盒体510的内部限定出用于储液的储液空间，储液空间与氧气处理装置300液路相通，以向氧气处理装置300补充电化学反应所需的电解液。
通过将储液模块500的盒体510设置于发泡层180内，并使盒体510的储液空间与氧气处理装置300液路相通，以利用盒体510所储存的液体向氧气处理装置300补充电解液，由于盒体510并未占据储物空间122，因此冷藏冷冻装置10能够在不影响容积率的情况下，利用储液模块500向氧气处理装置300补充电解液，使氧气处理装置300可持续性地调节储物空间122的氧气含量。
需要强调的是，对于气调保鲜而言，为便于储液模块500向氧气处理装置300补液，本领域普通技术人员容易想到采用就近原则，将补液模块设置在储物空间122内，这会压缩冷藏冷冻装置10的容积率。本申请的发明人通过创造性地将储液模块500安装在发泡层180内，这突破了现有技术的思想桎梏，为冷藏冷冻装置10在保持较高容积率的情况下实现可持续性地气调保鲜提供了新思路，同时也解决了储液模块500因易被物品触及而导致液体洒溢等多个技术性问题。
储液模块500的盒体510可以设置于发泡层180的任意部位，例如可以设置于内胆120的侧部，或者可以设置于内胆120的顶部、底部以及背部。对于法式冰箱或者T型冰箱而言，在一个示例中，储液模块500的盒体510可以设置于上部内胆120与下部内胆120之间的间隙中。
在一些可选的实施例中，箱体100还具有箱壳170，发泡层180形成于箱壳170和内胆120之间。箱壳170罩设于发泡层180的外侧，以与内胆120夹持发泡层180。
图4是图1所示的冷藏冷冻装置10的内胆120的示意性结构图。内胆120开设有开口状的交互窗口124，发泡层180具有与交互窗口124相通以供装配储液模块500的安装凹槽。在发泡层180成型之后，储液模块500可以装配至安装凹槽内，从而设置于发泡层180内。安装凹槽可以在发泡层180成型过程中预留出来。安装凹槽沿发泡层180的厚度方向朝向背离交互窗口124的方向凹陷，且与箱壳170之间形成间隙。换言之，安装凹槽并未贯穿发泡层180，这使得装配至安装凹槽的储液模块500不会紧贴箱壳170。也即，箱壳170与氧气处理装置300之间形成有一定厚度的隔热保温材料。
采用上述结构，储液模块500无需预装于发泡层180内，避免发泡过程对储液模块500的结构和性能产生不利影响，并且储液模块500的装配过程可以在储物空间122内执行，具备装配过程简单等优点。
通过在内胆120上开设交互窗口124，并在发泡层180中设置与交互窗口124相通的安装凹槽，且使安装凹槽与箱壳170之间形成间隙，储液模块500可以在发泡层180成型之后再安装至安装凹槽，这有利于简化储液模块500的拆装难度。并且由于安装凹槽并未贯穿发泡层180，因此本实施例的方案能够减少或避免因在发泡层180内安装储液模块500而导致冷藏冷冻装置10的保温性能明显降低。
储液模块500可以固定于安装凹槽内，固定方式包括但不限于螺接、卡接、铆接、焊接以及粘接。
在一些可选的实施例中，盒体510开设有连通储液空间的注液口514，且注液口514通过交互窗口124显露出来，从而允许外部液体注入储液空间。图5是图1所示的冷藏冷冻装置10的储液模块500的示意性结构图。图6是图5所示的冷藏冷冻装置10的储液模块500的示意性透视图。例如，注液口514设置于盒体510面朝储物空间122的侧壁上，以通过交互窗口124显露出来。
通过在内胆120上开设交互窗口124，并使盒体510的注液口514经交互窗口124连通储物空间122，可利用交互窗口124作为用户向储 液空间补液的操作窗口。由于交互窗口124可将注液口514显露出来，当储液空间的储液量不足时，外部液体可以经注液口514注入储液空间，因此，本实施例的上述方案可简化储液模块500的补液方式，使储液模块500可持续性地向氧气处理装置300补充电解液。
盒体510上设置有盖体550，盖体550可往复运动地设置在注液口514处，以打开或封闭注液口514。盖体550打开注液口514时，允许注液口514显露出来。通过在盒体510上设置盖体550，并利用盖体550打开或封闭注液口514，可使注液口514仅在接收外部液体时呈开放状态，从而可减少或避免异物进入储液空间，使储液空间所储存的液体保持洁净。
盖体550可以为按压式弹盖，其受压可转动地弹起，以至少部分地经由交互窗口124伸入储物空间122内，从而打开注液口514。
在一个示例中，盖体550的底部可以通过转轴连接至盒体510，并与盒体510可枢转地连接。当盖体550封闭注液口514时，其外表面与盒体510的外表面共面，此时盖体550的顶部可以通过卡接结构连接至盒体510；当需要打开注液口514时，可以按压盖体550的顶部，使盖体550的顶部与盒体510脱离，此时盖体550可以绕转轴转动，并且至少部分地伸入储物空间122，从而打开注液口514。
在了解本公开实施例的基础上，本领域技术人员应当易于获知按压式弹盖与盒体510之间的装配结构，本公开不再赘述。
在一些可选的实施例中，盒体510的至少一部分由透明材料制成，以形成用于显露盒体510的储液量的可视区域516。透明材料可以为聚甲基丙烯酸甲酯、聚碳酸酯、聚对苯二甲酸乙二醇脂或者聚丙烯等。
本实施例的可视区域516通过交互窗口124显露出来。可视区域516沿纵向延伸设置，并位于注液口514的下方。例如，可视区域516也设置于盒体510面朝储物空间122的侧壁上，以便通过交互窗口124显露出来。
通过在盒体510上设置可视区域516，并使可视区域516与交互窗口124相对，可利用交互窗口124作为用户观察储液空间液位的观察窗口。由于交互窗口124可将可视区域516显露出来，用户可以十分方便地观察储液空间的储液量，因此，本实施例的上述方案可使用户获得直 观的交互体验。当储液空间的储液量不足时，用户可以及时地采取补液措施。
在一个示例中，交互窗口124可以位于内胆120的侧壁上，安装凹槽相应设置于内胆120的侧壁与箱壳170的侧壁之间。
由于内胆120的侧壁不易被储物空间122所储存的物品所遮挡，且与用户的可活动区域距离较近，因此，在内胆120的侧壁上设置交互窗口124，并使储液模块500嵌入箱体100侧部的发泡层180内，可以在一定程度上降低用户与储液模块500之间的交互难度，用户无需挪动储物空间122所储存的物品便可以快捷地获取储液模块500的储液量信息，并且可以在储液模块500的储液量不足时及时执行补液操作。
在一些可选的实施例中，储液模块500可以进一步地包括液位传感器，设置于储液空间内，并用于检测储液空间的液位。在液位传感器检测到储液空间的液位低于设定值时，冷藏冷冻装置10可以发出报警信号，例如可以通过无线传输技术将报警信号输送给用户，以提醒用户及时补液。
在一些进一步的示例中，盒体510具有与内胆120的侧壁相平齐且封闭交互窗口124的第一侧壁以及与第一侧壁相对并且隐藏于安装凹槽内部的第二侧壁。注液口514位于第一侧壁上。交互窗口124的开口面积与盒体510的第一侧壁的表面积可以大致相同，使得盒体510的第一侧壁恰好封闭交互窗口124且使第一侧壁的外表面与内胆120侧壁的内表面连接成完整的平面，以使外形美观。
注液口514可以设置于第一侧壁的上部区段。可视区域516也可以设置于第一侧壁上，例如可以设置于第一侧壁的中部区段或者下部区段。
在一些可选的实施例中，氧气处理装置300具有壳体320和电极对，壳体320内限定出用于盛装电解液的电化学反应仓。电极对设置于电化学反应仓且用于通过电化学反应将储物空间122的氧气转移至电化学反应仓。
图7是根据本发明一个实施例的冷藏冷冻装置10的氧气处理装置300的示意性结构图。图8是图7所示的冷藏冷冻装置10的氧气处理装置300的示意性分解图。电极对可以包括阴极板330和阳极板340。电化学反应仓为阴极板330和阳极板340进行电化学反应的场所，其内可 以盛装碱性电解液，例如1mol/L的NaOH，其浓度可以根据实际需要进行调整。
壳体320具有侧向开口321。例如壳体320可以呈扁平的长方体形状。例如壳体320可以呈扁平的长方体形状。侧向开口321可以设置在壳体320的任意面上，例如顶面、底面或者侧面。在一个示例中，侧向开口321可以设置在壳体320的面积最大的面上。
阴极板330设置于侧向开口321处以与壳体320共同限定出用于盛装电解液的电化学反应仓，并用于通过电化学反应消耗储物空间122的氧气。空气中的氧气可以在阴极板330处发生还原反应，即：O2+2H2O+4e-→4OH-。
阳极板340与阴极板330相互间隔地设置于电化学反应仓内，并用于通过电化学反应向阴极板330提供反应物并生成氧气。阴极板330产生的OH-可以在阳极板340处发生氧化反应，并生成氧气，即：4OH-→O2+2H2O+4e-。
以上关于阴极板330和阳极板340的电化学反应的举例仅仅是示意性的，在了解上述实施例的基础上，本领域技术人员应当易于变换电化学反应的类型，或者针对适用于其他电化学反应类型的氧气处理装置300的结构进行拓展，这些变换和拓展均应落入本发明的保护范围。
壳体320具有连通电化学反应仓的补液口322。
盒体510也可以大致呈扁平的长方体形状。盒体510还具有连接于第一侧壁和第二侧壁之间且沿竖直方向相对设置的顶壁和底壁。底壁上开设有出液口511，出液口511连通补液口322，以向电化学反应仓补充电解液。储液空间所盛装的液体可以为水，或者也可以为电解液，其浓度可以低于电化学反应仓所盛装的电解液。
冷藏冷冻装置10还包括预埋于发泡层180内的补液管路420，补液管路420的第一端连通氧气处理装置300的补液口322，补液管路420的第二端连通储液模块500的出液口511，以将自出液口511流出储液空间的液体导引至补液口322，从而向电化学反应仓补液。出液口511高于补液口322，如此一来，储液空间内的液体可以在重力作用下自动流入电化学反应仓，而无需借助动力装置。
当然，在另一些示例中，出液口511也可以变换为低于补液口322 或与补液口322相平。此时，可以在补液管路420上安装泵，以在泵的作用下驱使储液空间内的液体流入电化学反应仓；或者可以利用虹吸原理，使储液空间内的液体流入电化学反应仓。
在一些进一步的示例中，补液管路420上可以设置有单向阀，用于允许来自出液口511的液体单向通过，保证流经补液管路420的液体的单向流动。
在一些进一步的实施例中，壳体320还具有连通电化学反应仓的排气孔323，用于排出电化学反应仓的氧气。
盒体510的顶壁上开设有进气口512和出气口513。其中，进气口512连通排气孔323，以允许排气孔323排出的氧气通入储液空间以过滤可溶性杂质，例如氧气所携带的电解液。出气口513用于允许过滤后的氧气向外排出。
冷藏冷冻装置10还包括预埋于发泡层180内的过滤管路430，过滤管路430的第一端连通氧气处理装置300的排气孔323，过滤管路430的第二端连通盒体510的进气口512，以将自排气孔323流出的氧气导引至出气口513，从而进入储液空间进行过滤。
储液模块500还可以进一步地包括滤气管540和出气管。其中，滤气管540从进气口512***储液空间，并延伸至储液空间的底部区段，以将待过滤的氧气导引至储液空间，使得氧气中的可溶性杂质溶解于储液空间。出气管从出气口513***盒体510内，并延伸至储液空间的上部区段，且位于储液空间所储存的液体上方，以将过滤后的氧气经其导引出。
采用上述方案，待过滤氧气可以在滤气管540的导引下到达储液空间，并且流经储液空间所储存的液体，使得氧气中的可溶性杂质溶解于储液空间，完成气体的净化。净化后的气体可以在出气管的导引下流入指定空间，从而起到调节空间氧气含量的作用。
在一个可选的实施例中，储液模块500还包括气阻机构530，设置于储液空间内，且将储液空间分隔出气路阻断的滤气区和非滤气区。其中，滤气区用于使流入进气口512的气体流经其中以实现过滤。非滤气区用于接收来自外部液体。
滤气区和非滤气区可以沿横向并列设置，气阻机构530阻断滤气区 和非滤气区之间的一部分液路，使滤气区和非滤气区在气路阻断的情况下保持液路相通。例如，气阻机构530为位于滤气区与非滤气区之间且自盒体510的顶壁下表面向下延伸并与盒体510的底壁上表面之间形成间隙的隔板状结构。滤气区位于气阻机构530的横向一侧，非滤气区则位于气阻机构530的横向另一侧。进气口512和出气口513可以分别设置于滤气区所在区域的顶壁上。注液口514则可以设置于非滤气区所在区域的顶壁上。
采用上述结构，通过在储液空间内设置气阻机构530，并利用气阻机构530将储液空间分隔出气路阻断的滤气区和非滤气区，可实现仅在滤气区内执行净化气体的功能。由于滤气区仅为储液空间的一个子空间，且与储液空间的其他区域之间的气路阻断，通入进气口512的气体仅能在滤气区内流动，而不会自由扩散至非滤气区而导致无法快速排放，因此本实施例的储液模块500具备较高的净化气体释放率。
在一些可选的实施例中，盒体510还具有连接于第一侧壁和第二侧壁之间且沿水平方向相对设置的第三侧壁和第四侧壁。第三侧壁和/或第四侧壁的外表面连接有固定件517，固定件517具有用于与螺钉配合以将盒体510固定于安装凹槽的螺孔。
以上实施例中，储物空间122可以为用于冷藏物品的冷藏空间。氧气处理装置300可以设置于储物空间122内。例如，冷藏空间可以指设置于冷藏间室内的储物容器600的内部空间。储物容器600上可以开设有换气口。氧气处理装置300可以设置于换气口处，以与储物空间122气流连通。
在另一个示例中，氧气处理装置300可以设置于发泡层180内，如图2和3所示，为便于示意各个部件的结构以及连接关系，图中隐去了发泡层180。此时，冷藏冷冻装置10可以进一步地包括预埋于发泡层180的换气管路200。换气管路200可包括进气管路210和回气管路220。
进气管路210用于将储物空间122的气体导引至阴极板330，回气管路220用于将流经阴极板330的气体导引回储物空间122，以降低储物空间122的氧气含量。例如，内胆120的胆壁上开设有连通进气管路210的第一端的第一换气口和连通回气管路220的第一端的第二换气口。每个换气口分别为形成于内胆120胆壁上的开口。进气管路210的第二 端以及回气管路220的第二端可以分别连通阴极板330的两端，具体地，进气管路210的第二端可以连通阴极板330的上风侧，回气管路220的第二端可以连通阴极板330的下风侧，使得流出进气管路210的气体可以在流经阴极板330之后流入回气管路220。
采用上述结构，利用进气管路210与回气管路220连通储物空间122与氧气处理装置300，储物空间122内的氧气含量较高的气体可以经进气管路210流动至阴极板330处，使阴极板330利用其中的氧气作为反应物进行电化学反应，形成氧气含量较低的低氧气体，这些低氧气体可以经回气管路220返回至储物空间122，从而起到降低储物空间122氧气含量的作用。
氧气处理装置300可以设置于发泡层180的任意部位，例如可以设置于内胆120的背部，或者可以设置于内胆120的顶部、底部以及侧部。对于法式冰箱或者T型冰箱而言，在一个示例中，氧气处理装置300可以设置于上部内胆120与下部内胆120之间的间隙中。
在一些可选的实施例中，发泡层180背对内胆120的一侧开设有与发泡层180的外部环境相通以供装配氧气处理装置300的装配凹槽182。图9是根据本发明一个实施例的冷藏冷冻装置10的箱体100的发泡层180的示意性结构图，图中示出了用于装配氧气处理装置300的发泡层以及装配凹槽182。
在发泡层180成型之后，氧气处理装置300可以装配至装配凹槽182内，从而设置于发泡层180内。装配凹槽182可以在发泡层180成型过程中预留出来。装配凹槽182沿发泡层180的厚度方向朝向靠近内胆120的方向凹陷，且与内胆120之间形成间隙。换言之，装配凹槽182并未贯穿发泡层180，这使得装配至装配凹槽182的氧气处理装置300不会紧贴内胆120。也即，内胆120与氧气处理装置300之间形成有一定厚度的隔热保温材料。
采用上述结构，通过在发泡层180背对内胆120的一侧开设连通发泡层180的外部环境的装配凹槽182，并使装配凹槽182与内胆120之间形成间隙，氧气处理装置300可以在发泡层180成型之后再安装至装配凹槽182，这有利于简化氧气处理装置300的拆装难度。并且由于氧气处理装置300并不会紧贴内胆120，因此本实施例的方案能够减少或 避免冷藏冷冻装置10的低温环境影响电化学反应的正常进行。
氧气处理装置300可以固定于装配凹槽182内，固定方式包括但不限于螺接、卡接、铆接、焊接以及粘接。
在一些可选的实施例中，箱体100还包括箱壳170，其罩设于发泡层180的外侧，以与内胆120夹持发泡层180。箱壳170具有背板，装配凹槽182形成于内胆120的背壁与箱壳170的背板之间。也就是说，本实施例的氧气处理装置300设置于内胆120背部的发泡层180内。箱壳170的背板可以封闭装配凹槽182的开口，以使外形美观。
在一个示例中，箱壳170的背板可以开设有正对装配凹槽182的安装口，在装配过程中，无需拆卸箱壳170的背板，可以直接通过安装口将氧气处理装置300固定至装配凹槽182内。在一个进一步的示例中，安装口处可以设置有盖板，用于遮蔽安装口，以使外形美观。在另一个示例中，可以先将氧气处理装置300固定至装配凹槽182内，然后再将箱壳170的背板覆盖在发泡层180的背部。
采用上述结构，氧气处理装置300无需预装于发泡层180内，避免发泡过程对氧气处理装置300的结构和性能产生不利影响，并且氧气处理装置300的装配过程可以在冷藏冷冻装置10的背部执行，具备装配过程简单等优点。
在一个示例中，当氧气处理装置300与储液模块500分别设置于发泡层180时。
在又一个示例中，箱体100内还限定出用于安装压缩机的压缩机室。氧气处理装置300可以设置于压缩机室内。例如，压缩机室的底部设置有用于固定压缩机的支撑板，氧气处理装置300可以直接或间接地设置于支撑板上。
在一个示例中，冷藏冷冻装置10还包括另一内胆150，其内侧限定出另一储物空间152，例如变温间室或者冷冻间室。冷藏冷冻装置10还具有预埋于发泡层180内的输氧管路440，其连通出气口513与另一储物空间152，以向另一储物空间152输送氧气，营造高氧保鲜气氛，提升冷藏冷冻装置10的保鲜性能。
在一些进一步的示例中，输氧管路440上也可以设置有单向阀，用于允许流向上述另一储物空间152的氧气单向通过，保证流经输氧管路 440的气体的单向流动。
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。
