Description

在冰箱下部设置倾斜排水管的冰箱 技术领域
本发明属于制冷设备技术领域，具体提供了一种在冰箱下部设置倾斜排水管的冰箱。
背景技术
蒸发器底置冰箱中，蒸发器设置于储物间室底部的制冷腔内，抬高了储物间室，方便用户取放底部储藏物。
蒸发器底置冰箱的散热机仓设置在冰箱的底部后侧，也即位于制冷腔的下后方，为了尽可能地扩大散热空间，散热机仓的前壁(又称为冰箱的底钢板)一般为倾斜设置。
排水管从制冷腔的底部向散热机仓内的蒸发皿排水。上述制冷腔与散热机仓的相对位置使得排水管的排水角度减小，相比于传统冰箱中排水管垂直穿过底钢板，蒸发器底置冰箱排水管与底钢板成锐角，在工艺上难于紧固，容易出现缝隙。在制冷腔与散热机仓之间进行发泡时，发泡料容易从穿管位置溢入散热机仓。另外排水管由于排水角度小，上述穿管位置也容易出现排水不畅的问题。
发明内容
本发明的一个目的是要提供一种克服上述问题或者至少部分地解决上述问题的在冰箱下部设置倾斜排水管的冰箱。
本发明的一个目的在于降低冰箱排水管穿入散热机仓位置的紧固难度。
本发明的一个进一步目的是避免排水管穿管位置发生溢料。
为实现上述目的，本发明提供了一种在冰箱下部设置倾斜排水管的冰箱，其包括：
箱体，其内限定有储物间室，储物间室的底部形成用于布置蒸发器的制冷腔，并且箱体在制冷腔的下后方形成有散热机仓，散热机仓的前壁从箱体底板的中部从前向后倾斜向上延伸；
蒸发皿，布置在散热机仓内；
排水管，从制冷腔的底部从前向后倾斜向下设置，穿过散热机仓的前壁后进一步延伸至蒸发皿，从而将制冷腔内的化霜水排至蒸发皿；
水管固定件，设置于排水管穿过前壁的位置，用于固定排水管，水管固定件具有第一固定面，第一固定面用于抵靠散热机仓的前壁。

可选地，排水管包括：
第一区段，其第一端与制冷腔的底部连接，其第二端穿过穿管孔并在外周缘形成有连管结构；
第二区段，与第一区段的第二端连接，并延伸至蒸发皿。
可选地，连管结构包括螺纹结构，并且冰箱还包括一固定螺帽，固定螺帽与螺纹结构可拆卸地连接，固定螺帽的端部用于与第二固定面抵靠，以紧固排水管以及水管固定件。
可选地，第一区段为硬管；第二区段的至少一部分为波纹软管；和/或
排水管的倾斜角度大于等于5°。
可选地，第一区段至少在穿过穿管孔的部分上在径向外周形成有沿轴向方向的定位筋；穿管孔在径向外周形成与定位筋配合的定位槽，以通过定位筋与定位槽配合对第一区段进限位。
可选地，穿管孔在第一固定面形成的孔口位于第一固定面的中部；第一固定面在孔口的四周分别具有抵触散热机仓的前壁的空间。
可选地，散热机仓的前壁在水管固定件对应的区域形成一凸台；以及
水管固定件嵌入设置凸台背侧的凹入部内。
可选地，上述在冰箱下部设置倾斜排水管的冰箱还包括：
风筒组件，设置于散热机仓的横向中部，将散热机仓沿箱体的横向方向分隔为第一散热腔和第二散热腔，风筒组件朝向第一散热腔的一侧安装有散热风机，风筒组件朝向第二散热腔的一侧安装有冷凝器；
压缩机，安装在第一散热腔内；蒸发皿安装在第二散热腔内。
基于前文的描述，本领域技术人员能够理解的是，在本发明前述的技术 方案中，蒸发皿布置在散热机仓内，排水管从制冷腔的底部从前向后倾斜向下设置，穿过散热机仓的前壁后进一步延伸至蒸发皿，排水管与散热机仓的前壁所在平面呈锐角，通过水管固定件的第一固定面抵靠散热机仓的前壁，利用水管固定件对排水管进行固定。第一固定面可以避免发泡溢料，提高连接可靠性。

如图1至图4所示，在本发明的一些实施例中，冰箱主要包括箱体1、压缩机2、风筒组件3、蒸发皿4和蒸发器5。
箱体1限定有储物间室11、散热机仓12和制冷腔13。其中，储物间室11不仅限于图中所示的两个，其还可以根据需要配置为其他数量，例如一个或多个。当储物间室11为一个的情况下，储物间室11可以是冷冻室、变温室或冷藏室。当储物间室11为两个及两个以上时，多个储物间室11包括冷冻室、变温室和冷藏室中的至少一种或多种。在具体实施本发明的技术方案时，本领域技术人员可以根据需要配置储物间室11的数量及其功能。
箱体1的底部后方具有散热机仓12。在一些实施例中，储物间室11的底部形成用于布置蒸发器的制冷腔13。也即制冷腔13可以设置于散热机仓12的前上方，而箱体1在制冷腔13的下后方形成有散热机仓12，从而实现蒸发器底置式冰箱。制冷腔13占用内胆的底部区域，抬高了储物间室11，降低用户对储物间室11进行取放物品操作时的弯腰程度，提升用户的使用体验。蒸发器5安装在制冷腔13内，用于向储物间室11内提供冷量。
散热机仓12被风筒组件3分隔为第一散热腔121和第二散热腔122，以对空间进行划分，分别布置不同部件。
图5是根据本发明一些实施例中冰箱的散热机仓12内主要部件分布示意图；沿冰箱的横向方向从左至右，压缩机2、风筒组件3和蒸发皿4依次布置在散热机仓12内。
风筒组件3设置于散热机仓12的横向中部，将散热机仓12沿箱体1的横向方向分隔为第一散热腔121和第二散热腔122，并且风筒组件3朝向第一散热腔121的一侧设置有风机固定结构，风筒组件3朝向第二散热腔122的一侧设置有冷凝器固定结构。压缩机2和蒸发皿4分别设置于第一散热腔121和第二散热腔122内。
压缩机2位于第一散热腔121内，通过制冷管路(图中未示出)连接冷凝器(图5中被风筒组件3遮挡，未能示出)。
蒸发皿4布置在散热机仓12内，具体地可以安装于第二散热腔122内，用于承接连接制冷腔13的排水管41排出的水。排水管41从制冷腔13的底部延伸至散热机仓12，也即排水管41的上端连通至制冷腔13的底部，排水管41的下端延伸至蒸发皿4。排水管41用于将冰箱的化霜水排放至蒸发皿4内，利用蒸发皿4将水蒸发至环境空气中。
排水管41的设置方式为从制冷腔13的底部从前向后倾斜向下设置，穿过散热机仓12的前壁53后进一步延伸至蒸发皿4，从而将制冷腔13内的化霜水排至蒸发皿4。
散热机仓12的底板在第一散热腔121和第二散热腔122的前部分别开设有散热进风口321和散热排风口322。冰箱下部的环境空气从散热进风口321进入散热机仓12，首先与压缩机2进行换热，然后通过散热风机和冷凝器后，加速蒸发皿4内水的蒸发，然后从散热排风口322排回冰箱下方。散热气流通畅，提高了各部件的散热效率。在冰箱的底板的下表面还可以进一步设置隔离散热进风口321和散热排风口322的隔离件，避免排出的散热后的空气又被重新吸入。
散热机仓12的底板又可称为压机支撑板，其左右两侧可以分别设置第一滚轮51和第二滚轮52。也即散热机仓12的底板在压缩机2相背于风筒组件3的一侧设置有第一滚轮51；散热机仓12的底板在蒸发皿4相背于风筒组件3的一侧设置有第二滚轮52。第一滚轮51和第二滚轮52用于在移动冰箱时进行滚动。
图6是根据本发明一些实施例冰箱的风筒组件3与散热风机32、冷凝器31的装配结构中的结构分解图。风筒组件3与散热风机32、冷凝器31形成预装配的一体件，形成一个用于通过散热气流的风筒结构，使得气流全部流经冷凝器31，在提高散热效率的同时，使得结构更加紧凑，简化装配过程。
风筒组件3设置于散热机仓12的横向中部，将散热机仓12沿箱体1的横向方向分隔为第一散热腔121和第二散热腔122。风筒组件3朝向第一散热腔121的一侧设置有风机固定结构，风筒组件3朝向第二散热腔122的一侧设置有冷凝器固定结构。也即风机固定结构朝向压缩机2的一侧，冷凝器固定结构朝向蒸发皿4的一侧。而风筒组件3沿前后方向设置。风机固定结构和冷凝器固定结构可以分别为卡接结构，分别卡接散热风机32的机壳以及冷凝器31。
散热风机32安装于风机固定结构上，用于促使形成从箱体外部进入并吹经第一散热腔121和第二散热腔122后排出箱体的散热气流。冷凝器31安装于冷凝器固定结构上，并利用散热气流进行冷却。气流依次通过压缩机2、冷凝器31以及蒸发皿4，对各部件依次散热，提高了散热效率。
风筒组件3在两侧分别设置风机固定结构和冷凝器固定结构，以用于装 配散热风机32和冷凝器31，形成一体式的风筒结构，使得散热风机32和冷凝器31占用的空间更小。散热机仓内部件的布置结构更加紧凑，为压缩机2以及蒸发皿4提供了更大的布置空间，有利于提高散热效率。相比于现有技术中将冷凝器设置于蒸发皿4的上方的方案，本实施例的结构减小了散热机仓12的高度方向的尺寸。
风筒组件3包括支架主体33和挡风板34。支架主体33呈方形筒状，沿箱体1的横向方向延伸设置，也即沿左右方向延伸。支架主体的筒形用于供散热气流通过。挡风板34从支架主体33的前端延伸，用于封挡第一散热腔121和第二散热腔122的前部区域，从而避免散热气流回风，仅允许气流从支架主体33的筒内吹过。
冷凝器31可以优选使用微通道冷凝器，从而节省冷凝器31占用的空间，便于与支架主体33进行配合。微通道冷凝器微通道之间的缝隙与散热气流的方向一致，散热气流全部需要通过冷凝器31，提高了换热效率。
在进行装配时，可以首先将冷凝器31、散热风机32与风筒组件3预先进行装配，形成一体式的预装组件，然后整体安装于箱体1内。
图7是根据本发明一些实施例冰箱中蒸发皿4的结构图。蒸发皿4布置在散热机仓12内，蒸发皿4沿冰箱的横向宽度设置有多个连管部42，多个连管部42分别适配不同箱体1宽度的排水管41的位置，从而利用多个连管部42中与排水管41位置正对的一个与排水管41连接，使得蒸发皿4承接排水管41排出的水。
蒸发皿4在多个连管部42的前部设置有防插挡板43，防插挡板43设置有与多个连管部42一一对应的限位插槽431，限位插槽431用于固定排水管41，一方面避免排水管41晃动，另一方面也增加了排水管41的支撑强度。
图7中示出的连管部42为两个，用于适配两种宽度规格的箱体1。在具体实施时，本领域技术人员可以根据需要设置连管部42的数量，通过连管部42适配不同规格的箱体。
排水管41在散热机仓12的底板的投影为沿箱体1前后方向的直线，并且排水管41从前至后倾斜向下设置，以依靠重力使水排至蒸发皿4。排水管41相对于箱体1的位置由制冷腔13的构造以及制冷腔13的排水口的位置决定，为了便于排水，排水管41要求尽量短，而且可以靠近箱体1的横向中心位置。为了便于排水管41顺利排水，要求排水管的41的排水角都可以倾 斜角。度大于等于5°。
由于上述制冷腔13与散热机仓12的相对位置，为了节省空间，散热机仓12的前壁53从所述箱体底板的中部从前向后倾斜向上延伸；而排水管41从前至后倾斜向下设置，排水管41与散热机仓12的前壁53所在平面成夹角较小，不便于紧固，为了解决这一问题，本实施例增加了水管固定件44。
图8是根据本发明一些实施例冰箱中排水管41与散热机仓12的前壁53的配合结构图，图9是图8所示的配合结构沿C-C方向的截面图，图10是图9所示的配合结构在区域D的局部放大图；图11是根据本发明一些实施例冰箱中排水管41与水管固定件44配合结构一个角度的示意图；图12是图11中水管固定件44的示意图；图13是根据本发明一些实施例冰箱中排水管41与水管固定件44配合结构另一角度的示意图；图14是图13中水管固定件44的示意图。图11-13中隐去了散热机仓12的前壁53。
散热机仓12的前壁53也可称为底钢板，由于封闭制冷机仓12，散热机仓12的前壁53与制冷腔13腔壁之间形成发泡空间，通过充注发泡料，星辰隔热层。如果紧固不可靠，排水管41穿过散热机仓12的前壁53的位置容易在充注发泡料时出现向散热机仓12溢料的问题。
水管固定件44设置于排水管41穿过前壁53的位置，用于固定排水管41，水管固定件44具有第一固定面441，第一固定面441用于抵靠散热机仓12的前壁53。第一固定面441可以为水管固定件44的前表面，整体贴靠前壁53，形成面接触，避免了因锐角设置导致接触不紧密的问题。
散热机仓12的前壁53供排水管41穿过的位置开设有前壁通孔，前壁通孔的形状与排水管41在散热机仓12的前壁53所在平面的截面形状一致。例如对于圆管状的排水管41，前壁通孔的形状为椭圆形。前壁通孔的形状与排水管41的截面形状一致，减小了排水管41与前壁53之间的间隙。
水管固定件44具有供排水管41穿过的穿管孔443，穿管孔443在第一固定面441形成的孔口形状与前壁通孔的形状一致，也即前壁通孔的形状为椭圆形的情况下，穿管孔443在第一固定面441形成的孔口形状为同样的椭圆形。
水管固定件44相背于第一固定面441的一侧形成第二固定面442，第二固定面442与排水管41的轴向方向垂直，使得穿管孔443在第二固定面442形成的孔口形状为与排水管41横截面一致。第二固定面442与排水管41的 轴向方向垂直，使得排水管41垂直穿过第二固定面442，以便与排水管41的紧固机构可以与水管固定件44的第二固定面442面接触，避免接触不紧密的问题。例如对于圆管状的排水管41，穿管孔443在第二固定面442形成的孔口形状同样为圆形。
排水管41包括：第一区段411以及第二区段412。第一区段411的第一端与制冷腔12的底部连接，第一区段411的第二端穿过穿管孔443并在外周缘形成有连管结构。第一区段411的第一端可以设置托板413，托板413的形状与制冷腔12的底部形状相匹配，并与制冷腔12底壁抵触，从而避免发泡过程中向制冷腔12溢料，堵塞排水口。
第二区段412与第一区段411的第二端连接，并延伸至蒸发皿4。第一区段411为硬管，避免被发泡料挤压，第二区段412的至少一部分为波纹软管，为调整长度和位置提供一定裕量。
连管结构可以为螺纹结构。并且冰箱还可以匹配设置一固定螺帽45，固定螺帽45与螺纹结构可拆卸地连接，固定螺帽45的端部用于与第二固定面442抵靠，以紧固排水管41以及水管固定件44。
水管固定件44改进了固定螺帽45的紧固面，固定螺帽45可以自由旋入，操作方便，可靠性高。
第一区段411至少在穿过穿管孔443的部分上在径向外周形成有沿轴向方向的定位筋(图中未示出)；穿管孔443在径向外周形成与定位筋配合的定位槽444，以通过定位筋与定位槽444配合对第一区段进限位，避免排水管41转动。
穿管孔443在第一固定面441形成的孔口位于第一固定面441的中部；第一固定面441在孔口的四周分别具有抵触散热机仓12的前壁53的空间，从而封闭排水管41的缝隙，避免溢料。
散热机仓12的前壁53在水管固定件44对应的区域形成一凸台，凸台略微向制冷腔13的方向凸出，进一步避免在排水管41处溢料。水管固定件44嵌入设置凸台背侧的凹入部内，也可以方便水管固定件44的安装。
至此，已经结合前文的多个实施例描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围并不仅限于这些具体实施例。在不偏离本发明技术原理的前提下，本领域技术人员可以对上述各个实施例中的技术方案进行拆分和组合，也可以对相关技术特征作出等同的更改 或替换，凡在本发明的技术构思和/或技术原理之内所做的任何更改、等同替换、改进等都将落入本发明的保护范围之内。
