Description

一种排水组件
本申请要求了申请日为2017年08月09日，申请号为201710675944.2，发明名称为“一种排水组件”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本本发明属于制冷设备领域，尤其是涉及一种排水组件和包括该排水组件的冰箱。
背景技术
对于目前市场上的冰箱来说，制冷间室例如如冷冻室均通过蒸发器发散冷量进行制冷，在一定周期内，当间室内温度趋于稳定时，化霜加热器会进行化霜，使得蒸发器上面附着的霜、冰晶等化成水，并通过冰箱内胆底部的排水管流入接水盘中，由于排水管与外界连通，当冰箱不处于化霜状态时，外界的热空气容易通过排水管倒流入间室内，使间室内温度一定幅度上升，从而加长了压缩机的运转时间，进而增加了冰箱的能耗。
为了解决上述问题，现有排水管大多采用半封闭式结构或者尽量减小排水口的管径，减少热空气倒流，但对于化霜水较少的冰箱而言，半封闭式的排水管结构适用性较差，对于减少热空气倒流的效果也不明显，并且其生产成本较高。
发明内容
为了解决上述问题之一，本发明提供了一种排水组件，包括：
排水管，所述排水管包括设置于顶端的接水槽、以及与所述接水槽相连通的管道，所述管道底端设置有出水口；
阀体，可自所述出水口装配入所述管道，所述阀体包括底座、以及自所述底座向上凸伸的凸柱，所述凸柱形成有堵头，所述堵头的外径与所述管道内径相适应，且所述堵头边缘沿其径向朝内凹陷形成有至少一处凹槽，所述凹槽与所述管道的内壁之间形成引流道。
作为本发明的进一步改进，所述堵头远离所述底座的一端设置有导引段，所述导引段的直径自其靠近所述底座的一端朝远离所述底座的另一端逐渐缩小。
作为本发明的进一步改进，所述凸柱还包括有连接所述堵头及所述底座的柱体，所述柱体外径小于所述管道内径，所述管道内的水可自所述引流道流至所述底座。
作为本发明的进一步改进，所述底座的内表面向上凸伸形成有抵持部，当所述阀体装配入所述管道时，所述出水口可与所述抵持部相抵持，以使所述出水口与所述底座的内表面相互间隔并形成空隙。
作为本发明的进一步改进，所述底座的形状与所述出水口形状相适应，且所述底座的周侧向上围设有凸边，当所述阀体装配入所述管道时，所述凸边可包围所述出水口使所述底座与所述管道相固定。
作为本发明的进一步改进，所述凸边凹陷形成有若干间隙，水可沿所述引流道流至所述底座经所述间隙流出。
作为本发明的进一步改进，所述管道靠近出水口的一侧向外凸伸形成有至少一个定位块，当所述阀体装配入所述管道时，所述定位块可插入并与所述间隙相卡持，以限制所述阀体相对所述管道发生旋转。
作为本发明的进一步改进，所述管道与所述接水槽呈一夹角倾斜设置，所述凸柱与所述底座呈同一夹角倾斜设置，并且，在所述阀体装配入所述管道后，接水槽、出水口和底座均相互平行。

本发明的有益效果：本发明提出的排水组件，在不更改排水管的管径的情况下，通过阀体，使堵头和管道的内壁相配合生成引流道将水排出，进一步控制了出水口的大小，保证顺利出水的同时也减少了倒流入管内的空气，简单方便，降低了生产成本。

在本实用新型的描述中，除非另有规定和限定，需要说明的是，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是机械连接或电连接，也可以是两个元件内部的连通，可以是直接相连，也可以通过中间媒介间接相连，对于本领域的普通技术人员而言，可以根据具体情况理解上述术语的具体含义。
下面参照附图详细描述本发明一实施例中的具体实施方式。
参图1所示，本发明提出了一种排水组件，包括有排水管100和阀体200。具体的，排水管100包括设置于顶端的接水槽110、以及与接水槽110相连通的管道120，管道120还包括出水口121，具体的，在本实施例中，接水槽110内表面凹陷形成有漏水口111，出水口121通过管道120与漏水口111相连通，接水槽110中接收的水可汇集入漏水口111流入管道120后从出水口121流出。
进一步的，参图2所示，阀体200可自出水口121装配入管道120，阀体200包括有底座210、以及自底座210向上凸伸的凸柱220，并且凸柱220形成有堵头221，在本实施例中，堵头221设置于凸柱220上远离底座210的一端，且堵头221的外径与管道120的内径相适应，当阀体200装配入管道120时，堵头221也随即插入管道120中，与管道120内壁相贴合，同时，为了使管道120中的水流出，堵头221边缘沿其径向朝内凹陷形成有至少一处凹槽，并与管道120的内壁之间形成引流道222，当管道120内水流至堵头221位置时，可由引流道222流出，在本实施例中，对称设置有四个凹槽，也即形成有四条相互对称的引流道222。
进一步的，为了防止在排水过程中水积于堵头221处，堵头221远离底座210的一端设置有引导段223，引导段223的直径自其靠近底座210的一端朝远离底座210的另一端逐渐缩小。具体的，在本实施例中，引导段223设置为圆台形，其侧面为倾斜面，当有水排入管道120内时，可沿着引导段223的侧面流至引流道222中，再流出管道120外。
同时，凸柱220还包括有连接堵头221以及底座210的柱体224，并且柱体224的外径小于管道120的内径，管道120内的水可自引流道222流至底座210。
进一步的，底座210的内表面向上凸伸形成有抵持部211，当阀体200装配入管道120时，出水口121可与抵持部211相抵持，以使出水口121与底座210的内表面相互间隔并形成空隙，具体的，在本实施例中，抵持部211设置为凸筋结构，通过设置抵持部211，使出水口121与底座210内表面之间相互间隔不贴靠，可使管道120内的水排除后直接流入底座210内。
同时，底座210的形状与出水口121的形状相适应，底座210的周侧向上围设有凸边212，当阀体200装配入管道120时，凸边212可包围出水口121并且使底座210与管道120相固定，进而实现阀体200与管道120相固定；同时，凸边212上凹陷形成有若干间隙213，水可沿引流道222流至底座210经间隙213流出。
进一步的，管道120靠近出水口121的一侧向外凸伸形成有至少一个定位块122，当阀体200装配入管道120时，定位块122可插入并与所述间隙213相卡持，以限制阀体200相对管道120旋转，使整个排水组件更加稳定，在本实施方式中，所述定位块122设置有一个。
在本实施例中，管道120与接水槽110呈一夹角倾斜设置，为了使堵头221与管道120内壁更加紧密的配合，凸柱220也与底座210呈同一夹角倾斜设置，并且在阀体200装配入管道120后，接水槽110、出水口121和底座210均相互平行；将管道120相对于接水槽110倾斜设置，能使排水时水流得到一定程度上的缓冲，在一定程度上也减轻了排水时管道120内产生的噪音。
参图3所示，结合排水组件截面图，描述整个排水过程，当接水槽110内接收到水时，水汇集与接水槽110内壁凹陷处，即漏水口111，后进入管道120内流至堵头221处，通过引导段223流入引流道222并汇集与底座210内，由于出水口121与抵持部211相抵持后产生空隙，底座210内的水从空隙经凸边212上的间隙213流出。
同时，本发明还提出了一种冰箱，包括：壳体、设置于壳体内的内胆及设置与壳体与内胆之间的压机仓，压机仓内设置有用以接水的接水盘；冰箱还包括如上所述的排水组件，排水组件部分设置于压机仓内，且设置于所述接水盘的上方，以使得冷凝水流过排水组件并将水排出至接水盘内。
本发明提出的排水组件，在不更改排水管100的管径的情况下，使堵头221和管道120的内壁相配合生成引流道222将水排出，进一步控制了出水口121的大小，保证顺利出水的同时也减少了倒流入管内的空气，简单方便，降低了生产成本。
应当理解，虽然本说明书按照实施例加以描述，但并非每个实施例仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施例中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施例。
上文所列出的一系列的详细说明仅仅是针对本发明的可行性实施例的具体说明，并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施例或变更均应包含在本 发明的保护范围之内。
