本发明提出一种排水管及移动空调。
参照图1至8，图1为本发明排水管一实施例的结构示意图；图2为图1的主视图；图3为图2的A-A截面剖视图；图4为图1的左视图；图5为图4的B-B截面剖视图；图6为本发明排水管一实施例与移动空调的底盘组装的结构示意图；图7为图6中C处局部放大图；图8为图6中D处局部放大图。
在本发明实施例中，参照图1、6及图8，排水管用于移动空调的水泵80排水，该排水管包括主管体100及分别与主管体100的两端连接的进水管体200和排水管体300；进水管体200、排水管体300采用注塑成型，主管体100采用吸塑成型。
具体地，为了将移动空调中的冷凝水及时收集处理掉，以免影响空调正常的工作，一般会将这些冷凝水引流喷洒在打水轮90中，利用打水轮90的高度运转将冷凝水蒸发处理。而将冷凝水引流至打水轮90上，一般采用普通的排水软管进行输送冷凝水，用以达到引流作用。但这种普通的排水软管在输送冷凝水的过程中，很容易因为水流的压力会产生弯折形变，使得处于排水软管中的冷凝水会滞留，甚至在压力越来越大的情况下，冷凝水会出现倒流至水泵80，造成水泵80或其他部件损坏。因此为了解决排水软管容易弯折形变的问题，采用由刚性较强且容易成型的材料制作管体，在本实施例中，优选采用增强型聚丙烯材料，当然在其他实施例中还可以采用丙烯酸及其酯类聚合得到的聚合物。鉴于要适应移动空调的底盘安装，排水管的进水端和排水端的结构均比较复杂，因此将排水管优选分设三部分：主管体100、进水管体200和排水管体300；其中进水管体200和排水管体300分别连接在主管体100的两端。为了提高结构复杂程度不同的部位的生产效率及效果，将复杂程度较高的进水管体200和排水管体300采用注塑成型方法生产，而复杂程度较低的主管体100采用吸塑成型方法生产。如此，按照不同的结构复杂程度，灵活利用不同的生产方式用以分开生产不同的部位，既节省整个排水管的生产时间，又提高了整个排水管的刚性强度。
在本实施例中，主管体100适应移动空调的底盘安装，设置为大致Z字形状；在其他实施例，主管体100还可以设置呈其他形状，以适应移动空调的底盘安装。
本发明技术方案通过采用将排水管优选包括主管体100、进水管体200和排水管体300三部分；其中进水管体200和排水管体300分别连接在主管体100的两端；由于进水管体200和排水管体300的结构复杂故采用注塑成型方法生产，主管体100的结构相对简单故采用吸塑成型方法生产；如此，灵活利用不同的生产方式用以分开生产不同的部位，既节省整个排水管的生产时间，又提高了整个排水管的刚性强度，最终使得流通于排水管的冷凝水排放顺畅。
进一步地，参照图1至图3和图8，进水管体200包括直接与主管体100连通的主进水管段210及连接主进水管段210与水泵80的支进水管段220。
具体地，该主进水管段210与主管体100水平或大致水平设置，支进水管段220竖直或大致竖直设置，主进水管段210与支进水管段220连接形成一L型；鉴于水泵80与打水轮90之间的高度有差异，通过主进水管段210与支进水管段220组合连通于主管体100上，适应移动空调的底盘安装应用。主进水管段210与支进水管段220为一体成型结构，保证了整个进水管体200的密封性。
进一步地，参照图2、3及图8，进水管体200还包括一端与主进水管段210连通的回流管段230，回流管段230的另一端与外界连通；回流管段230的直径小于支进水管段220的直径，且回流管段230的长度与底盘的深度相当。
具体地，排水管在输送冷凝水的过程中，水泵80向支进水管段220泵水时，支进水管段220中的空气容易与流速较快的水混合一起，形成气泡，而该气泡碰撞在支进水管段220的内壁，导致有异声，影响用户使用。因此为了解决支进水管段220的异声，增设一回流管段230，该回流管段230一端与主进水管段210连通的回流管段230，其另一端与外界连通，且该回流管段230优选与支进水管段220平行设置，当流速较快的水进入支进水管段220后，支进水管段220中的空气在流速较快的水冲击下，空气可经回流管段230排出，如此可避免空气与水在支进水管段220中形成异声；为了让回流管段230在释放空气的同时尽量减少排水，将回流管段230的直径小于支进水管段220的直径。优选地，回流管段230延伸至底盘的水槽内最低水位，防止从回流管段230出来的水滴在水面产生异音。
进一步地，参照图5，为了加强主进水管段210与主管体100之间的密封性，在本实施例中由于整个排水管都采用增强型聚丙烯材料制成，因此主进水管段210与主管体100之间可采用超声波焊接或注塑手段连接。这两种连接方式都采用有热熔手段对主进水管段210与主管体100连接的端面加热而融合，待温度降低后，主进水管段210与主管体100连接的端面固化为一体。在本实施例中，主排水管段310与主管体100之间也可采用超声波焊接或注塑手段连接。
进一步地，参照图4、5及图8，排水管体300包括主排水管段310、第一支排水管段320及第二支排水管段330，主排水管段310与主管体100连通，第一支排水管段320和第二支排水管段330均连通在主排水管段310上。
具体地，该主排水管段310与主管体100水平或大致水平设置；第一支排水管段320和第二支排水管段330竖直或大致竖直设置，且第一支排水管段320与第二支排水管段330优选平行设置。鉴于水泵80与打水轮90之间的高度有差异，通过主排水管段310、第一支排水管段320及第二支排水管段330组合连通于主管体100上，适应移动空调的底盘安装应用。在本实施例中，第一支排水管段320和第二支排水管段330都用于将冷凝水喷射在打水轮90上；一方面通过第一支排水管段320和第二支排水管段330同时对打水轮90喷射，增大打水轮90的蒸发面积，让冷凝水不会只集中在打水轮90的某一位置，使得冷凝水蒸发速度更快；另一方面可增大排水管的排水量，提高排水效率。当然，在其他实施例中，根据实际的应用，将排水管体300还可设置其他数量的排水管段。主排水管段310、第一支排水管段320及第二支排水管段330为一体成型结构，保证了整个排水管体300的密封性。
进一步地，参照图5，为了更好地控制两个排水管段的流量，第二支排水管段330的直径小于第一支排水管段320的直径。如此设置，用户可根据不同型号的移动空调选择不同的直径组合的排水管段。在本实施例中，第一支排水管段320的直径优选为5mm，第二支排水管段330的直径优选为3mm。
进一步地，参照图1、5和图6，主进水管段210的外侧壁上设有与其呈垂直排布的第一安装板211，第一安装板211上设有第一螺孔211a；主排水管段310的外侧壁上设有与其呈平行排布的第二安装板311，第二安装板311上设有第二螺孔311a。鉴于主进水管段210和主排水管段310都与主管体100平行连接，如此将第一安装板211设置在主进水管段210，第二安装板311设置在主排水管段310上，再通过螺钉旋入第一螺孔211a和第二螺孔311a，可让位于主管体100两端的进水管体200和排水管体300稳定地固定于移动空调的底盘上，防止水泵80在输送冷凝水的过程中将排水管冲出。
本发明还提出一种移动空调，该移动空调包括所述排水管，该排水管的具体结构参照上述实施例，由于本移动空调采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。其中，参照图6至图8，所述排水管的主进水管段210与水泵80连通，所述排水管的第一支排水管段320及第二支排水管段330的管口面向打水轮90设置。如此，冷凝水可从主进水管段210进入主管体100，再经主管体100从第一支排水管段320和第二支排水管段330喷射在打水轮90上。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
