具体实施方式
图1是根据本发明一个实施例的冰箱10的示意性结构图。图2是根据本发明一个实施例的冰箱10的部分结构的示意性结构图。冰箱10一般性地可包括箱体100和补液器具220。
箱体100的内部形成储物空间110。储物空间110用于存放食材、药品等物品。例如，箱体100的内部可以限定出储物间室，本实施例的储物空间 110可以指储物间室的内部空间。又如，储物间室内可以设置有储物容器，例如抽屉，在一些实施例中，储物空间110可以指储物容器的内部空间。
补液器具220设置于箱体100内，并隐于储物空间110之外，用于接收外部液体并向冰箱10内的特定部件提供。补液器具220隐于储物空间110之外是指，补液器具220并未设置在储物空间110之内，并未占据储物空间110的任何位置。
例如，箱体100内可以形成有位于储物空间110外侧的安装空间，补液器具220可以设置于安装空间内。例如，安装空间可以位于压机仓内、发泡料内或者风道盖板后侧的送风风道内。
补液器具220与需要补液的特定部件之间可以直接或间接地连通。例如，当补液器具220与需要补液的特定部件之间直接地连通时，补液器具220的内部可以限定出储液腔，补液器具220所接收的外部液体可以暂存于储液腔内，连通储液腔与需要补液的特定部件，即可向特定部件提供液体；当然补液器具220的内部也可以不限定出储液腔，虽然此时的补液器具220不具备储液功能，但是直接连通补液器具220与需要补液的特定部件，也可向特定部件提供液体。当补液器具220与需要补液的特定部件之间间接地连通时，补液器具220与特定部件之间可以设置有储液容器210，该储液容器210一方面连通补液器具220的出液端，另一方面连通特定部件，并用于将来自补液器具220的液体供应给特定部件。
本实施例的冰箱10，箱体100内设置有用于接收外部液体并向特定部件提供的补液器具220，由于该补液器具220隐于储物空间110之外，因此可在不影响冰箱10有效容积的前提下增设该补液器具220，基于该补液器具220，当向特定部件补液时，无需由专业的售后工程师拆卸特定部件，能够巧妙地降低补液难度。
需要说明的是，补液器具220隐于储物空间110之外，是相对于补液器具220的一般使用状态而言的。当补液器具220处于加注状态时，例如处于用于接收外部液体的补液状态，可能并未隐于储物空间110之外。并且补液器具220隐于储物空间110之外，并不意味着补液器具220完全不可见地藏起来，只要保证补液器具220不占据储物空间110即可，即便用户通过储物空间110可以观察到补液器具220，也视为补液器具220隐于储物空间110之外。
在一些可选的实施例中，补液器具220可往复枢转地设置，并用于通过转动伸入储物空间110之内，以便接收外部液体。补液器具220可往复枢转地设置是指，补液器具220可绕轴往复地转动，从而在一般使用状态和加注状态之间来回切换。其中，一般使用状态是指补液器具220隐于储物空间110之外的状态，加注状态是指补液器具220伸入储物空间110之内的状态。
例如，补液器具220可以在需要接收外部液体时通过转动伸入储物空间110之内，以便用户向其添加液体，而当补液器具220不需要接收外部液体时，则可以通过转动回复至初始位置，并隐于储物空间110之外，不再占据任何储物空间110。
由于补液器具220可往复枢转地设置，并用于通过转动伸入储物空间110之内，以便接收外部液体，因此，当补液器具220接收外部液体时，并不需要拆卸下来，冰箱10可在不拆卸补液器具220的前提下使其执行补液功能，构思巧妙，方案独特。
并且，由于补液器具220的转动方式为枢转运动，该转动方式可以避免补液器具220的出液端发生位移，因此不会导致液路连接结构遭到破坏，从而有利于提高液路连接结构的稳定性。同时，这也避免了在补液的前后通过人工通断液路连接结构，克服了补液过程需由人工参与、以及补液过程复杂的技术难题。补液器具220的出液端用于向与补液器具220液体连通的部件输出液体。
在一些可选的实施例中，冰箱10还包括分隔件120，其形成储物空间110的壁，且其上开设有缺口。本实施例的储物空间110是指储物间室的内部空间。例如储物空间110可以具有后壁、顶壁、底壁以及位于横向两侧的两侧壁。分隔件120可以形成储物空间110的任一壁，或者可以为任意多个壁的组合。
补液器具220设置于分隔件120背朝储物空间110的一侧，并用于在转动时穿过缺口从而伸入储物空间110之内。亦即，上述缺口作为补液器具220伸入储物空间110的窗口，补液器具220可以通过转动正向或反向地穿过缺口，从而伸入储物空间110之内或者自储物空间110之内复位至储物空间110之外。
通过在分隔件120上开设缺口，为补液器具220的“伸入”和“复位”提供了通道，使补液器具220的隐藏式安装、以及补液便捷式安装得以实现。
例如，在一些实施例中，分隔件120为冰箱10的风道盖板，其形成储物空间110的后壁。补液器具220设置于缺口的后侧。本实施例的冰箱10可以为风冷冰箱10，风道盖板的后侧可以形成送风风道。由于送风风道具有一定的空间体积，因此，可以为补液器具220提供安装空间。本实施例的冰箱10并不需要专门为补液器具220专门地开辟其他安装空间，不会对有效容积产生影响。
当然，在另一些实施例中，分隔件120可以变换为储物空间110的侧壁，但不限于此。
图3是图2所示的冰箱10的部分结构的另一视角的示意性结构图。在一些可选的实施例中，冰箱10还包括罩壳140，与分隔件120固定连接或与分隔件120一体成型，并罩设于分隔件120背朝储物空间110的一面，且罩壳140的内部限定出安装空间，用于容纳补液器具220。
利用罩壳140来容纳补液器具220，可以提高补液器具220在箱体100内的装配稳定性，避免补液器具220与其他部件之间的液路连接结构产生变形或者扭曲。
例如，当分隔件120为风道盖板时，罩壳140可以自风道盖板的背面向后凸出形成。通过对风道盖板的成型模具进行改造，可以一体成型出具有上述罩壳140的风道盖板，工艺简单，制造成本不高。当罩壳140与风道盖板固定连接时，固定连接方式可以为螺接、粘结、焊接或者热压融合连接等。
在一些可选的实施例中，风道盖板上可以设置有遮蔽盖板，以分隔储物空间110与罩壳140的内部空间。冰箱10还包括储液容器210，其连通补液器具220的出液端，并作为中间储液容器，用于向需要补液的特定部件提供液体。储液容器210可以设置容纳在罩壳140的内部。
储液容器210的至少一部分侧壁由透明材料制成，以形成液位显示区216。透明材料所处的部位形成透明区域。储液容器210的内部情况可通过透明区域进行展示。例如，用户可通过透明区域观察到储液容器210内的液位。
风道盖板在与储液容器210的液位显示区216相对的部位可以设置有液位观察窗，以便用户观察储液容器210内的液位。液位观察窗可以设置在遮蔽盖板上。
由于储液容器210的至少一部分侧壁由透明材料制成，遮蔽盖板上设置 有液位观察窗，用户可通过对透明区域进行观察获知储液容器210的液位，以评估是否执行补液操作，因此，基于本实施例的上述方案，可使储液容器210的液位可视化，便于用户及时获知储液容器210内的液位，并在发现储液容器210内的液位不足时及时补液，从而有利于提升用户使用体验。
图4是根据本发明一个实施例的冰箱10的补液器具220的示意性结构图。图5是图4所示的冰箱10的补液器具220的另一视角的示意性结构图。图6是图4所示的冰箱10的补液器具220的又一视角的示意性结构图。在一些可选的实施例中，补液器具220具有供液体流动的补液流道222以及连通于补液流道222的出液端222a的中空筒状转轴224，中空筒状转轴224的内部形成用于导引液体的导引流道，以将来自补液流道222的液体导引至特定部件。补液器具220所接收的外部液体经由补液流道222流至中空筒状转轴224的导引流道，并在流出导引流道的出液端之后流入特定部件内。
中空筒状转轴224为空心结构，且轴向两端的两个端口开放。导引流道可以连通补液流道222的出液端222a与特定部件的进液端，或者连通补液流道222的出液端222a与储液容器210的注液孔212，并通过储液容器210这一中间储液容器向特定部件提供液体。补液流道222的出液端222a可以为开口，中空筒状转轴224自补液流道222的出液端222a的开口周缘向外延伸形成。其中，“向外”是相对于补液流道222而言的，是指远离补液流道222的方向，例如向下或者向侧部。
在一些可选的实施例中，补液流道222的底面为斜面222b，且其出液端222a位于斜面222b的末端，这便于液体向其出液端222a汇集，防止补液流道222内产生液体残留，并且由于斜面222b可以促使流经的液体加速流动，因此可以提高补液速率，实现快速补液。
斜面222b的周缘向上延伸形成周壁222c，补液器具220的周壁222c与斜面222b共同限定出补液流道222。
导引流道为中空筒状转轴224的内部中空通道。补液流道222用于接收外部液体并向导引流道输送。当需要向补液器具220注入液体时，用户可从补液流道222的外部执行补液操作，并向补液流道222注液，从而使补液流道222的液体向导引流道输送。通过转动补液器具220，可使其转动至用户易于执行补液操作的合适位置。例如，通过转动可使补液器具220的端部伸入储物空间110并到达靠近用户的位置，以便于用户注液。
由于通过转动补液器具220，可调整执行补液操作的位置，因此补液器具220和/或储液容器210不需要安装在用户易于接触的位置、或者用户易于执行补液操作的位置，这大大减少了补液器具220和/或储液容器210在选择安装位置时的制约因素，可以实现补液部件的多样化灵活安装，尤其适于隐藏式安装，避免占据某些特定空间，提升美观度。
中空筒状转轴224作为补液器具220往复枢转的转轴。即，补液器具220绕中空筒状转轴224进行枢转。也即是说，本实施例的中空筒状转轴224具备双重功能，既可以提供用于输送液体的通道，又可以作为与需要补液的特定部件实现转动连接的连接部。基于此，补液器具220在转动的过程中，补液流道222并不会发生任何位移，可以保持其与储液容器210或需要补液的特定部件之间始终处于连通状态，结构十分巧妙。
在一些可选的实施例中，需要补液的特定部件为直接消耗液体的耗液部件。在另一些实施例中，作为中间储备仓的储液容器210也可以视为需要补液的特定部件。当补液器具220的中空筒状转轴224直接连通需要补液的特定部件时，该特定部件上可以开设有注液孔212，中空筒状转轴224可伸入注液孔212，并利用注液孔212的周缘下表面限制中空筒状转轴224的直线运动自由度。
补液器具220与中空筒状转轴224的旋转轴线与中空筒状转轴224的中心轴线同轴。注液孔212的位置以及补液器具220的安装位置可以根据实际需要进行设置，例如，注液孔212可以位于需要补液的特定部件的顶部，补液器具220可以设置在需要补液的特定部件的上方，此时补液器具220的旋转轴线方向与中空筒状转轴224的旋转轴线方向可以为竖直方向。当然，注液孔212可以变换为位于需要补液的特定部件的侧壁，补液器具220可以设置在需要补液的特定部件一侧，此时补液器具220的旋转轴线方向与中空筒状转轴224的旋转轴线方向可以为水平方向。
在一些实施例中，中空筒状转轴224自补液流道222的出液端222a向下延伸设置。此时注液孔212位于需要补液的特定部件的顶部。补液器具220的中空筒状转轴224竖直向下插入注液孔212，这便于液体依靠自身重力作用经由导流通道流入注液孔212。
下面将以需要补液的特定部件为储液容器210、且注液孔212位于储液容器210的顶部的情况为例，对冰箱10的结构作进一步介绍。
图7是根据本发明一个实施例的冰箱10的储液容器210的示意性结构图。图8是图7所示的冰箱10的储液容器210的示意性俯视图。
储液容器210上开设有用于注入液体的注液孔212。补液器具220可枢转地设置于储液容器210上方，且连通储液容器210，用于向储液容器210提供液体。其中补液器具220的中空筒状转轴224穿过注液孔212并与注液孔212的下周缘配合，以限制中空筒状转轴224沿其旋转轴线方向相对于注液孔212的直线运动自由度。也就是说，在转动补液器具220时，通过中空筒状转轴224与注液孔212的孔壁下周缘进行配合，会阻止中空筒状转轴224相对于注液孔212沿竖直方向移动，使得中空筒状转轴224在竖直方向上不会相对于注液孔212发生位移。
图9是根据本发明一个实施例的冰箱10的补液器具220与储液容器210的装配结构的示意图。图10是图9所示的冰箱10的补液器具220与储液容器210的装配结构的示意性透视图。
其中，图9(a)示出了处于一般使用状态的补液器具220与储液容器210之间的装配结构，图9(b)示出了处于加注状态的补液器具220与储液容器210之间的装配结构，图9(c)示出了处于加注状态的补液器具220与储液容器210的另一视角的装配结构。其中，一般使用状态是指补液器具220不需要加注液体的状态，加注状态是指补液器具220可加注液体的状态。
在一些可选的实施例中，中空筒状转轴224的下缘周向带有外凸卡爪224c，外凸卡爪224c的上表面抵靠于注液孔212的孔壁下周缘，以实现配合。在转动补液器具220时，外凸卡爪224c的上表面始终位于注液孔212的孔壁下周缘的下方，从而限制中空筒状转轴224沿其旋转轴线方向相对于注液孔212的直线运动自由度。
在一些可选的实施例中，注液孔212沿储液容器210的顶壁厚度方向贯穿设置，且其孔壁的底部区段沿径向向内延伸形成中空环状凸缘212a。本实施例的注液孔212为贯穿储液容器210的顶壁厚度方向的光孔。在竖直方向上，注液孔212可划分为第一孔段和第二孔段。其中，第二孔段为注液孔212的底部区段，其限定于中空环状凸缘212a内，第一孔段为位于底部区段上方的区段。注液孔212的底部区段的孔径小于注液孔212的上部区段的孔径，即，第二孔段的孔径小于第一孔段的孔径。
由于中空环状凸缘212a沿径向向内延伸，因此可作为托台，起定位作 用。当中空筒状转轴224插入注液孔212时，中空环状凸缘212a可支撑中空筒状转轴224的部分区段(例如下述第一区段224a)，使中空筒状转轴224定位插在注液孔212内。
中空筒状转轴224包括位于中空环状凸缘212a上方的第一区段224a和插入中空环状凸缘212a的第二区段224b。本实施例中，第一区段224a插入第一孔段内并位于中空环状凸缘212a的上方，中空环状凸缘212a限制第一区段224a向下移动。第二区段224b插入第二孔段内，即插入中空环状凸缘212a的中空通道内。
外凸卡爪224c形成在第二区段224b的下缘周向。本实施例的外凸卡爪224c限制中空筒状转轴224向上移动。外凸卡爪224c自第二区段224b的外壁沿径向向外延伸形成。
第一区段224a的轴径大于第二区段224b的轴径，且第一区段224a的下表面的周缘抵靠于中空环状凸缘212a的上表面，使第一区段224a始终处于中空环状凸缘212a的上方。
利用中空环状凸缘212a限制第一区段224a向下移动，并利用外凸卡爪224c限制中空筒状转轴224向上移动，以定位中空筒状转轴224和补液器具220，在补液器具220转动过程中，有利于提高补液器具220与储液容器210之间的装配稳定性，从而确保转动过程的可靠性，确保补液通道的畅通。
在一些可选的实施例中，注液孔212的孔壁沿径向向外延伸形成装配槽214，以允许外凸卡爪224c通过装配槽214由上至下地移至注液孔212的孔壁下周缘。亦即，装配槽214相当于扩展了注液孔212，并提供了外凸卡爪224c的活动空间。当将补液器具220装配至注液孔212时，在中空筒状转轴224由上至下地移动时，外凸卡爪224c由上至下地通过装配槽214，并移动至注液孔212的孔壁下周缘。当外凸卡爪224c移动至注液孔212的孔壁下周缘之后，转动补液器具220，外凸卡爪224c会转动至注液孔212的孔壁下方，使外凸卡爪224c的上表面与注液孔212的孔壁下表面相互抵压。
采用上述结构，补液器具220整体可以灵活便捷地进行拆卸，若补液器具220与储液容器210的二者之一出现损坏，均可以针对损坏件进行单方面的更换，这就大大降低了补液部件的维修成本。
图11是图9所示的补液器具的中空筒状转轴与储液容器的注液孔之间的装配结构的示意性仰视图。在一些可选的实施例中，注液孔212的孔壁的 下表面形成有多个凸点212b，多个凸点212b形成在同一圆周上，补液器具220的外凸卡爪224c上相应形成有供任一凸点212b插入其中以实现卡接配合的插孔224d，从而定位并悬停补液器具220，使补液器具220在转动至某些特定的角度或位置时与注液孔212的孔壁下表面锁紧并保持悬停状态，不再发生移动或转动。凸点212b与插孔224d之间可以通过过盈配合的方式实现卡接。
在一些可选的实施例中，凸点212b可以为三个，其中一个凸点212b位于装配槽214的相对侧，该凸点212b用于将补液器具220限定在一般使用状态。另一凸点212b与上一凸点212b之间的夹角可以为30～120°，例如可以为90°，用于将补液器具220限定在加注状态。
在一些可选的实施例中，储液容器210的底部区段开设有出液孔218，用于与特定部件连通，以将其内的液体向特定部件提供。特定部件为需要补液的部件，例如下述氧气处理装置300。
由于冰箱10的内部空间有限，供用户执行补液操作的空间并不充足，当采用上述实施例的补液器具220时，储液容器210可以隐藏于储物空间110的外部，当储液容器210内的液位较低需要补液时，通过转动补液器具220，使其到达靠近用户的位置，即可进行补液，这克服了储液容器210占用储物空间110、且储液容器210的补液困难等难题，为特定部件的正常连续运行提供了良好保障，有利于推动特定部件的推广应用，降低维护成本。
在一些可选的实施例中，冰箱10还包括氧气处理装置300，氧气处理装置300为耗液装置，且作为需要补液的特定部件。本实施例的氧气处理装置300为电解装置，其具有电解腔312和电极对，电解腔312用于盛装电解液，电极对设置于电解腔，并用于浸于电解液，且通过电化学反应处理氧气，例如消耗氧气或者产生氧气，从而调节储物空间110的氧气含量，使储物空间110营造适宜的保鲜环境。氧气处理装置300与储物空间内110的至少一部分气流连通。
图12是根据本发明一个实施例的氧气处理装置300的示意性结构图。储液容器210与电解腔312相连通，用于向电解腔312补液。例如，氧气处理装置300可包括壳体310，壳体310的内部限定出电解腔312。壳体310上开设有连通电解腔312的补液口。
补液器具220用于与电解腔直接或间接地连通，以向电解腔提供液体。 例如，当补液器具220与电解腔直接地连通时，补液器具220的中空筒状转轴224可以直接插入补液口内。
当补液器具220与电解腔之间通过储液容器210间接地连通时，补液器具220的中空筒状转轴224可以插入储液容器210的注液孔212内。储液容器210的底部具有出液孔218，出液孔218与补液口之间可以通过管路连通。由于电化学反应的进行会导致电解腔312内盛装的电解液减少，因此利用储液容器210连通电解腔312可以利用储液容器210内的液体弥补电解腔312的电解液损失，避免氧气处理装置300因电解液不足而导致氧气处理功能失效。
图13是图12所示的氧气处理装置300的部分结构的示意性分解图，图中示出了壳体310和阳极部321。在一些可选的实施例中，电极对包括阳极部321和阴极部322。例如，空气中的氧气可以在阴极部322发生还原反应，即：O2+2H2O+4e-→4OH-。阴极部322用于与电源负极连接。阳极部321用于与电源正极连接。并且阳极部321与阴极部322相互间隔地设置于电解腔312内，用于在电解电压的作用下通过进行电化学反应向阴极部322提供反应物。阴极部322产生的OH-可以在阳极部321可以发生氧化反应，并生成氧气，即：4OH-→O2+2H2O+4e-。阳极部321和阴极部322可以分别为板状电极。
壳体310上可以开设有装配口，阴极部322可以设置于装配口处，以与壳体310共同限定出用于盛装电解液的电解腔312。阳极部321与阴极部322相对，并设置于电解腔312内。当需要利用氧气处理装置300消耗储物空间110的氧气含量时，使阴极部322与储物空间110直接或间接地气流连通即可。壳体310上可以开设有排气口314，用于排出阳极部321产生的氧气。当需要利用氧气处理装置300提升储物空间110的氧气含量时，使壳体310的排气口314与储物空间110直接或间接地气流连通即可。
采用上述结构，冰箱10能对储物空间110的氧气进行处理，以顺应低氧保鲜的发展理念，延长果蔬等食材的保存期限，提高冰箱10的保鲜性能。由于氧气处理装置300的阳极部321所生成的氧气可被加以利用，提升储物空间110的氧气含量，因此，本实施例的冰箱10具备较高的气调能力，能够同时营造低氧保鲜气氛和高氧保鲜气氛。
储液容器210可以高于氧气处理装置300的电解腔312设置，以依靠高 度差、利用重力作用自动地向电解腔312补充液体。当然，储液容器210的高度也可以设置低于或者等于氧气处理装置300的电解腔312，此时可利用液泵装置所提供的动力抽取储液容器210内的液体、并将液体补充至电解腔312中。
氧气处理装置300的电源可以为电池，或者可以为其他供电结构。例如，当氧气处理装置300设置在冰箱10内时，冰箱10可以利用主控板向氧气处理装置300提供电源，或者可以利用冰箱10内部其他部件的供电结构向氧气处理装置300提供电源。
本实施例的冰箱10，当使补液器具220与氧气处理装置300的电解腔312直接或间接地连通时，补液器具220所接收的外部液体可以供应给氧气处理装置300，弥补电解腔312的电解液损失，从而为冰箱10的氧气处理装置300能够正常连续工作提供保障，促进气调保鲜理念的推广应用。
当然，补液器具220和/或储液容器210的安装位置并不限于以上实施例所提及的位置，例如，其还可以安装在门体(例如瓶座)上、间室的搁物架之上或者底部、抽屉之上或外部、冰箱10的侧壁内外或者顶部内外等等。
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。
