具体实施方式
下面将结合附图，对本公开一些实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开所提供的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
除非上下文另有要求，否则，在整个说明书和权利要求书中，术语“包括(comprise)”及其其他形式例如第三人称单数形式“包括(comprises)”和现在分词形式“包括(comprising)”被解释为开放、包含的意思，即为“包含，但不限于”。在说明书的描述中，术语“一个实施例(one embodiment)”、 “一些实施例(some embodiments)”、“示例性实施例(exemplary embodiments)”、“示例(example)”、“特定示例(specific example)”或“一些示例(some examples)”等旨在表明与该实施例或示例相关的特定特征、结构、材料或特性包括在本公开的至少一个实施例或示例中。上述术语的示意性表示不一定是指同一实施例或示例。此外，所述的特定特征、结构、材料或特点可以以任何适当方式包括在任何一个或多个实施例或示例中。
需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
在描述一些实施例时，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请中的具体含义。
“A和/或B”，包括以下三种组合：仅A，仅B，及A和B的组合。
本文中“适用于”或“被配置为”的使用意味着开放和包容性的语言，其不排除适用于或被配置为执行额外任务或步骤的设备。
如本文所使用的那样，“约”、“大致”或“近似”包括所阐述的值以及处于特定值的可接受偏差范围内的平均值，其中所述可接受偏差范围如由本领域普通技术人员考虑到正在讨论的测量以及与特定量的测量相关的误差(即，测量系统的局限性)所确定。
相关技术中，冰箱产品内的供水管路通常是在冰箱的箱体进行发泡之后再安装到箱体内。但由于与该供水管路相对应的加热机构(例如加热器和加热管道等)以及密封结构等相关器件较多，且上述相关器件的结构较为复杂，对安装精度要求较高，因此在箱体发泡之后再安装供水管路便容易出现供水管路加热不充分或者箱体密封性较差而导致冰箱内冷气泄露的问题，进而容易导致供水管路内发生结冰而堵塞等现象，影响制冰装置的制冰效果。
基于此，本公开一些实施例提供一种冰箱100。请参阅图1～图7，冰箱100包括发泡箱体1、制冰装置2、外管3和送水管4。发泡箱体1包括箱体10和形成在箱体10中的发泡层12。
其中，图1是根据本公开一些实施例的一种冰箱100的剖视图。图2是图1中的P区域的放大结构图。图3是图1沿A-A方向的剖视图。图4是图1中外管3的结构图。图5是图4中B区域的放大结构图。图6是图4中C区域的剖视图。图7是图4中C区域的分解结构图。
如图1所示，箱体10可采用长方体结构。
在一些示例中，箱体10内设置有相互分隔的多间制冷间室11。
示例性的，该多间制冷间室11的功能可以相同，这样可以对食物进行分区存放，以方便用户对食物进行取用。
又示例性的，该多间制冷间室11的功能也可以不同，例如包括冷冻室、冷藏室以及变温室中的至少两者，这样可以将不同种类的食物存放入不同功能的制冷间室11，从而满足该食物所需的冷冻、冷藏或者变温等不同的制冷需求。
值得说明的是，多间制冷间室11可沿竖直方向上下分隔布置，或沿水平方向左右分隔布置。
箱体10中形成有发泡层12。发泡层12所占的空间可称为发泡空间。示例性的，箱体10包括内壳和罩在内壳上的外壳。内壳和外壳之间的空间中至少部分为发泡空间。其中，箱体10的内壳为围成制冷间室11的壳体。例如，发泡层12可以形成于箱体10的外壳的内侧壁上，此时，发泡层12与箱体10的外壳的内侧壁，两者可以直接接触。又例如，发泡层12可以形成于箱体10的内壳的外侧壁上，此时，发泡层12与箱体10的外壳的内侧壁，二者可以直接接触。当然，发泡层12还可以同时与箱体10的内壳以及外壳接触。
在此基础上，发泡层12可通过将发泡材料填充于各个制冷间室11所对应的箱体10的外壳与内壳之间的空间中进行发泡而形成。
制冰装置2设于箱体10内，用于为冰箱100提供制冰功能。
在一些示例中，制冰装置2可设置在所有制冷间室11(例如冷藏室或冷冻室)的顶部，这样可以方便于从冷藏室或冷冻室的顶部由上至下对制冰装置2所产生的冰块进行容纳。
外管3与制冰装置2相连通。外管3部分地埋设于发泡层12内，并被发泡层12包覆。也即，外管3埋设于发泡层12且被发泡层12所包覆的部分与发泡层12为直接接触，且两者之间可以固定连接。此时，发泡层12与外管3可以形成一体式结构(即两者形成为一个整体)，发泡层12与外管3之间相对位置比较固定，不易发生松动。
在一些示例中，可通过制冰装置2的安装支架对外管3的一端进行定位， 以将外管3预先安装在箱体10的外壳与内壳之间，再往箱体10的外壳与内壳之间注入发泡材料，使得发泡材料发泡，从而形成发泡箱体1。此时，外管3部分地埋设于发泡层12内。由于外管3与发泡材料采用一体固化成型，因此，外管3可以被发泡层12所包覆，从而实现箱体10的预装。
送水管4穿设于外管3内，送水管4与制冰装置2连通。这样可以将送水管4内的水输送至制冰装置2中，从而利于制冰装置2进行制冰。
本公开一些实施例提供的冰箱100中，由于外管3在发泡层12形成之前预埋入箱体10的外壳与内壳之间，然后与发泡材料发泡之后所形成的发泡层共同形成一个整体，这样可以降低外管3的安装难度，同时还有助于保障外管3密封性能。
在一些示例中，外管3的一端作为出水端，该出水端与制冰装置2相连通，外管3的另一端则作为进水端。外管3内具有用于供水的管路通道，以供送水管4伸入。
在一些实施例中，请参阅图4、图6和图7，送水管4活动地穿设于外管3内。
这样可以将送水管4插入外管3内以进行使用；同时还可以根据需要，从外管3中拔出送水管4，以方便对送水管4或者外管3进行检查和检修。
示例性的，送水管4一端伸入布置于外管3内靠近其出水端的位置，这样有助于将送水管4内的水通过外管3的出水端输送至制冰装置2中。
在一些示例中，送水管4可采用PE管，PE管具有良好的耐用性，且使用寿命较长。
在一些实施例中，请参阅图2，外管3包括管路组件30，管路组件30的外壁上包覆有加热层36。例如，加热层36可以直接覆盖在管路组件30的外壁。
通过加热层36对管路组件30的外壁进行加热，可以有效防止管路组件30内部结冰。加热层36随管路组件30埋设于发泡层12内，这样可以简化管路组件30内部的加热结构，在组装时无需考虑加热结构的安装问题。
需要说明的是，加热层36可采用常见的加热结构。例如，加热层36为缠绕在管路组件30外壁上的加热丝。
请参阅图2～图4，在一些实施例中，管路组件30包括相互连通的出水头31和管套33。其中，出水头31远离管套33的一端与制冰装置2相连通。管套33至少部分地埋设在发泡层12内；送水管4穿过管套33并伸入布置于出水头31内。
值得说明的是，送水管4伸入布置于出水头31内，这样可以减小送水管4的出水端与外管3的出水端之间的距离，从而避免送水管4中的水流入外管3中容易受到外界温度影响而发生结冰。因此，这样设计有助于将送水管4内的水稳定输送至制冰装置2中。
在一些示例中，出水头31可采用铝材制作而成，这样可以有效提高加热层36在出水头31外壁上的加热效果。
图8是图7中出水头31的结构图。图9是图8的剖视图。
请参阅图8和图9所示，在一些实施例中，出水头31包括出水管部311和进水管部312，出水管部311和进水管部312呈夹角相连。
示例性的，出水管部311和进水管部312可以一体成型设置，也即，出水管部311和进水管部312可以通过一体注塑成型工艺制成出水头31。又示例性的，出水管部311和进水管部312也可以固定连接(例如采用焊接等方式)。本公开对此不作限制。
请参阅图5，并结合图3所示，出水管部311设于制冰装置2的顶部，出水管部311具有相对的顶端3112和底端3111，该顶端3112相较于底端3111远离制冰装置2，且出水管311的顶端3112与进水管部312连通，出水管部311的底端3111与制冰装置2连通。
这样设计，进入出水管311中的水由于重力作用可以更好地流进制冰装置2中，从而有利于实现对制冰装置2进行良好的水供给。
在此基础上，送水管4伸入布置于进水管部312内。这样有助于将送水管4内的水稳定输送至出水管311中。
示例性的，出水管部311可以竖直设置，这样有利于出水管部31与制冰装置2之间的连接。又示例性的，出水管部311也可以倾斜设置。在上述情况下，在竖直方向上，位于出水管部311的最高位置即为出水管部311的顶端3112，位于出水管部311的最低位置即为出水管部311的底端3111。
请继续参阅图5，在一些实施例中，进水管部312由出水管部311的顶端3112向斜上方弯折延伸。也即，进水管部312远离出水管部311的顶端3112的一端相较于进水管部312连接出水管部311的顶端3112的一端更加远离制冰装置2。
这样设计，当送水管4伸入布置于进水管部312内时，送水管4内的水流进入到进水管部312内，由于重力作用，水流能够顺着进水管部312的内侧壁自动流入出水管部311内，进而可以为制冰装置2提供比较稳定的水流。
在一些示例中，进水管部312与出水管部311的夹角大于90°。在此情 况下，出水管部311例如可以竖直设置。
需要说明的是，进水管部312与出水管部311的夹角略大于90°即可。示例性的，进水管部312与出水管部311的夹角范围为91°～95°。例如，进水管部312与出水管部311的夹角可以为91°、93°、95°等。这样可以使进水管部312占用较小的空间，同时有利于为制冰装置2提供稳定的水流。
在另一些示例中，进水管部312与出水管部311的夹角小于或等于90°。在此情况下，出水管部311例如可以倾斜设置。
请参阅图5～图9，在一些实施例中，出水管部311的底端3111凹设有缺口槽3110。
缺口槽3110的设置能够有效防止出水管部311的底端3111的端口由于负压而导致的水膜堆积，进而避免水膜在低温环境下结冰而堵住出水管部311的底端3111的出水口，导致出水管部311的底端3111的出水口不能往制冰装置2中注水的问题。
示例性的，该缺口槽3110可以为上窄下宽的梯形槽；又示例性的，缺口槽3110也可以呈圆弧形结构。
可以理解的是，缺口槽3110可设置多个。多个缺口槽3110可沿出水管部311的周向间隔布置。
请参阅图6，在一些示例中，出水管部311的底端3111的出水口的内径在竖直方向上由上至下逐渐变大。这样可使出水管部311的出水口逐渐变宽，进而可以减少水流从出水管部311进入到制冰装置2中的阻力。
在一些示例中，出水管部311的底端3111的端口的沿线与缺口槽3110之间采用圆角结构，这样可以有效防止水膜堆积而出现结冰的问题。
请参阅图6，并结合图3所示，在一些实施例中，出水头31还包括沿出水管部311的周向，设置在出水管部311的外壁上的固定板313。该固定板313固定贴设在制冰装置2上。
通过固定板313的设置，有利于实现出水头31与制冰装置2之间的固定连接。同时固定板313固定贴设在制冰装置2上，有助于提高出水头31与制冰装置2之间的连接紧密性。
示例性的，固定板313可固定贴设在制冰装置2的顶部。
需要说明的是，在同时设置固定板313以及上述缺口槽3110的情况下，多个缺口槽3110均位于固定板313下方的位置，这样在将固定板313固定贴设在制冰装置2上时，可以保障从出水管部311的出水口流出的水均能进入到制冰装置2中。
请参阅图9，并结合图6所示，在一些实施例中，出水头31还包括设置在进水管部312内的限位筋条3121。限位筋条3121被配置为限定送水管4的端部伸入进水管部312内的位置。
这样设计，可以在对送水管4进行插拔时，有效避免送水管4的端部伸入温度较低的出水管部311内，进而可以有效避免送水管4内出现结冰的问题。
在一些示例中，限位筋条3121具有用于送水管4抵靠的抵靠端，抵靠端位于进水管部312内靠近出水管部311的位置，送水管4的端部伸入进水管部312内之后能够抵靠在该限位筋条3121的抵靠端上，从而将送水管4的端部限定在进水管部312内的位置。
请继续参阅图9，在一些实施例中，限位筋条3121设于进水管部312内的顶部侧壁上。这样设计，可以防止残留水滞留在限位筋条3121的边侧，导致其逐步堆积使得残留水结冰长大，从而有利于避免出水头31中结冰而造成堵塞的问题。
请参阅图3、图4和图6，在一些实施例中，管路组件30还包括连接在出水头31和管套33之间的连接管32，连接管32与出水头31和管套33中的至少一者可拆卸连接。
由于管套33至少部分地埋设在发泡层12内，而出水头31需要与制冰装置2相连接，因此容易因为管套33的长度较短而增加管套33与出水头31之间的连接难度。而本公开所提供的冰箱100，利用连接管32分别与出水头31和管套33连接，有利于提高出水头31和管套33之间的连接过渡性，使得管路组件30整体的连接稳定性增加，同时还有助于减小出水头31和管套33连通设置的难度。
值得说明的是，在管路组件30外壁包覆有加热层36的情况下，示例性的，请参阅图2，加热层36可以设置管套33的外壁上。又示例性的，加热层36也可以设置在出水头31和连接管32的外壁上。
请参阅图6和图7，在一些实施例中，连接管32包括呈夹角相接的延伸段3201和连接段3202。连接段3202远离延伸段3201的一端与管套33连接。
延伸段3201远离连接段3202的一端与出水头31连接，且延伸段3201的延伸方向与出水头31的与连接管32相连的端部的轴向一致。这样有利于送水管4顺着延伸段3201插入出水头31或者从出水头31中抽出，从而提高送水管4的插入或者抽出效率。
在一些示例中，延伸段3201远离连接段3202的一端与进水管部312远 离出水管部311的一端连接，且延伸段3201的延伸方向与进水管部312的延方向一致，这样设置，可以方便于送水管4顺着延伸段3201插入进水管部312或者从进水管部312中抽出。
示例性的，连接段3202可以沿直线延伸。又示例性的，连接段3202也可以呈弧形弯曲延伸。通过上述设置，可以方便于连接管32与管套33之间进行连接。
值得说明的是，在延伸段3201与连接段3202之间可以呈圆滑过渡相接。
仍请参阅图6和图7，在一些实施例中，管路组件30还包括设于出水头31和连接管32的连接处的胶塞34。胶塞34被配置为密封出水头31与连接管32的连接处的缝隙。
这样设计，利用胶塞34可以实现出水头31与连接管32之间的密封连接，从而有助于避免送水管4中的水在进入到管路组件30中之后从出水头31与连接管32的连接处的缝隙中漏出，从而可以确保送水管4中的水能够稳定有效地输送至制冰装置2中。
请参阅图9，并结合图6，胶塞34上开设有供送水管4伸入的穿孔341。胶塞34与送水管4在穿孔341处过盈配合。
在送水管4通过穿孔341插入进水管部312内时，胶塞34可以将送水管4进行固定，从而使送水管4稳定在进水管部312内。同时，上述设计还能够防止进水管部312内的水从胶塞34与送水管4之间的缝隙中流到连接管32内，即防止水倒流。此外，通过上述设计，连接管32和管套33之间的密封问题也无需考虑，从而有利于管套33与连接管32之间的装配。
请参阅图7和图8，在一些实施例中，连接管32与出水头31可拆卸连接。
在此基础上，出水头31具有第一装配环314，第一装配环314设于出水头31的与连接管32相连的端部上，且沿该端部的周向延伸。
连接管32具有第二装配环324，第二装配环324设于连接管32的与出水头31相连的端部上，且沿该端部的周向延伸。
在第一装配环314和第二装配环324中，其中一者具有沿周向间隔布置的多个卡凸3141，另一者具有沿周向间隔布置的多个卡扣321；所述多个卡扣321与所述多个卡凸3141相扣接。
这样设计，利用第一装配环314和第二装配环324上相对应的卡凸3141与卡扣321相扣接，即可使连接管32与出水头31稳固地连接在一起。
请继续参阅图7和图8，在一些实施例中，多个卡凸3141位于第一装配环314上，第一装配环314设于出水头31的与连接管32相连的端部的外壁 上；连接管32的设有第二装配环324的端部套设在出水头31的设有第一装配环314的端部上。
这样将连接管32套设在出水头31上，有利于连接管32与出水头31之间具有较强的密封性。
在出水头31包括上述进水管部312的情况下，第一装配环314设置于进水管部312的靠近连接管32的一端的外壁上。对应的，第二装配环324设置于连接管32的靠近进水管部312的端部。连接管32的该端部套设在出水管部311的对应端部上，能够使上述卡扣321与卡凸3141相扣接。即当需要将连接管32与出水头31进行连接时，可将连接管32套接在进水管部312的端部上，利用卡扣321与卡凸3141相扣接，便可将连接管32与出水头31稳固地连接在一起。
此外，在出水头31和连接管32之间还设有胶塞34的情况下，第一装配环314与进水管部312靠近连接管32的端部之间留有间距，这样可以方便胶塞34套设在出水头31的端部。在连接管32套接在出水头31上时，胶塞34夹设于第一装配环314和第二装配环324之间。这样可以简化管路组件30的密封要求。
请参阅图8，卡凸3141面向连接管32的侧壁边沿形成有导向面31411，该导向面31411在进水管部312径向向外的方向上向逐渐远离卡凸3141的方向倾斜。由此，当卡扣321与卡凸3141相扣接时，卡扣321可顺着该导向面31411顺利扣接在卡凸3141上。可以理解的是，该导向面31411可以是倾斜的斜面，也可以是圆滑过渡的曲面。
请参阅图6和图7，第一装配环314上凹设有与多个卡凸3141呈周向间隔设置的防呆卡口3142。第二装配环324上设有与多个防呆卡口3142相嵌合的多个防呆块322；在多个卡扣321与多个卡凸3141相扣接时，多个防呆块322嵌合于多个防呆卡口3142内。
当需要对连接管32与出水头31进行连接时，可先将第二装配环324上的防呆块322与第一装配环314上的防呆卡口3142对齐，再将连接管32的端部套设在进水管部312一端，此时可使连接管32的卡扣321与进水管部312的卡凸3141顺利扣接。若连接管32上的防呆块322与装配环314上的防呆卡口3142并未对齐，则连接管32的卡扣321难以顺利扣接在进水管部312的卡凸3141上。通过连接管32上的防呆块322以及装配环314上的防呆卡口3142的设置，能够实现连接管32与出水头31之间的快速连接。
图10是根据一些实施例的连接管32与套管33的连接图。
请参阅图10，并结合图1和图4所示，管套33被配置为能够弯曲地埋设在发泡层12内。这样设置，能够对冰箱内的安装空间形成较低的要求，从而使得该管路组件30能够适应不同型号、不同尺寸的冰箱。
请参阅图10，并结合图6，在一些实施例中，连接管32与管套33可拆卸连接。
在此基础上，在连接管32与管套33中，其中一者的连接端上设有定位块331，另一者的连接端上设有与定位块331相适配的定位槽323。这样设计，可以增加连接管32与管套33之间的连接灵活度，有利于管路组件30的装配。
在一些示例中，定位块331设置于管套33的与连接管32相连接的端部的外壁；定位槽323设置于连接管32的与出水头31相连接的端部。连接管32的端部套设在管套33上，使得定位块331嵌合于定位槽323内。这样设置，能够使连接管32按特定的方向和角度对管套33进行连接，从而方便管路组件30的快速安装和定位。
示例性的，定位块331可沿管套33的轴向延伸，定位块331沿其长度方向可插接在定位槽323内。
请参阅图4，在一些示例中，管套33的远离连接管32的另一端设有固定座35，该固定座35固设于发泡箱体1内，并外露于发泡层12。送水管4能够穿过固定座35上的开孔伸入管套33内。这样设置，可使得管套33和送水管4在发泡箱体1内的位置比较固定，从而可提高管路组件30和送水管4的安装稳定性，进而提高其使用寿命。
基于上述技术方案，本公开上述实施例至少具有如下优点和积极效果：
本公开一些实施例所提供的冰箱100中，可利用预先埋设于发泡层12内的外壳3形成管路通道，配合送水管4穿设在该管路通道中，以实现对制冰装置2进行供水。由于预先埋设于发泡层12内的外管3与箱体10可以共同形成一个整体结构，这样可简化管路通道内的密封要求和安装难度。
图11是根据一些实施例的一种冰箱100的制造方法流程图。
请参阅图11，并结合图1～4所示，本公开一些实施例提供一种冰箱100的制造方法。该方法包括以下步骤：
S1：往冰箱100的箱体10的发泡空间中预装入外管3。
其中，箱体10包括内壳和罩在内壳上的外壳。内壳和外壳之间的空间中至少部分为上述发泡空间。
在一些示例中，外管3可以通过定位机构进行定位并置于发泡空间内，以使得外管3在发泡空间中保持其位置不发生改变。
S2：往箱体10的发泡空间中注入发泡材料，使发泡材料发泡形成发泡层12，并使得外管3部分地埋设于发泡层12内且被发泡层12包覆。
示例性的，将发泡材料注入发泡空间之后，发泡材料进行发泡，在发泡材料发泡完成之后所形成的发泡层12可以较好地填充该发泡空间。此时，外管3部分地埋设于发泡层12内且被发泡层12包覆，之后通过模具定型，将箱体10的外壳与内壳进行固化粘接，即可形成发泡箱体1。
值得说明的是，发泡箱体1的制作步骤不限于以上描述，例如，可在箱体10的外壳与内壳粘接之后填充发泡材料也应当在本公开的考虑范围之内。此处不再进行赘述。
S3：将送水管4穿入外管3，并与制冰装置2相连通。
上述冰箱100的制造方法中，由于箱体10中的外管3在发泡层12制作之前预先安装，在发泡层12形成之后可以与其形成一体，这样可以简化外管3的管路通道内的密封要求和安装难度。
在一些实施例中，上述定位机构可采用制冰装置2的安装支架，利用该安装支架可以对外管3的一端进行定位，以实现对外管3的固定。
需要说明的是，步骤S2和步骤S3的顺序可以互换。
虽然已参照一些实施方式描述了本公开，但应当理解，所用的术语是说明和示例性、而非限制性的术语。由于本公开能够以多种形式具体实施而不脱离发明的精神或实质，所以应当理解，上述实施方式不限于任何前述的细节，而应在随附权利要求所限定的精神和范围内广泛地解释，因此落入权利要求或其等效范围内的全部变化和改型都应为随附权利要求所涵盖。
