在一些可选实施例中，所述排水面325从所述第二端壁324向所述第一端壁323倾斜向下设置，倾斜角为6-10°，将所述排水面35倾斜设置，更加有利用自然排水，图6中的箭头代表自然排水的流向示意图，从所述第二端壁324向所述第一端壁323的方向。
在一些可选实施例中，所述接水装置3还包括：第二排水嘴35，所述第二排水嘴35设置于所述排水面325的所述第二端壁324上，所述第二排水嘴35用于作为水泵排水的出口，避免冷凝水长时间积聚在所述接水装置3中。
在一些可选实施例中，图7是根据一示例性实施例示出的蒸发器和接水装置连接结构的剖面图，如图7所示，所述凸起311至所述排水面325的所述第二侧壁322之间设有集水槽33，所述集水槽33位于所述凸起311至所述排水面325的所述第二侧壁322的中间位置。
在所述凸起311和所述第二侧壁322之间设置集水槽33，可以更好 地将冷凝水凝聚在所述集水槽33中，便于实用水泵排水，避免冷凝水长时间积聚在所述接水装置3中，对所述凸起311造成侵蚀，影响所述凸起311的使用寿命。
在一些可选的实施例中，在送风系统2进行送风后，所述第一侧壁321和所述排水面325采用采用渐开线形过渡段连接成功避免了采用直角连接时存在的紊流现象和噪音大的问题。
图8是根据一示例性实施例示出的蒸发器和接水装置连接结构的剖面图的局部放大图，如图8所示，所述集水面的所述第二侧壁322的高度为h。
在一些可选的实施例中，基圆直径也可根据所述接水装置的所述第二侧壁322的高度h来确定，其中基圆直径的范围需要大于等于0.5*h且小于等于1.5*h，其中h的取值大于等于15mm且小于等于25mm。
在一些可选的实施例中，若h的取值为20mm，则基圆直径的范围是大于等于10mm且小于等于30mm。
在一些可选的实施例中，若h的取值为20mm，则基圆直径的取值可为25mm。
在一些可选实施例中，如图8所示，所述蒸发器翅片1的所述尖角11的底部距离所述防水层31的尺寸为e，其中e的取值范围是大于等于3mm且小于等于5mm，避免所述蒸发器翅片1的所述尖角11将所述接水装置3的所述防水层31戳破。
在一些可选的实施例中，所述等边三角形的边长L的取值范围为e+10mm，即L大于等于13mm且小于等于15mm，该取值范围能够有效地保证所述蒸发器翅片1和所述凸起311的接触面的长度，不增加蒸发器的阻挡面，从而保证风量和风阻不受影响。
若L的取值过大，则会造成换热面积的减小，影响空调室内机的制冷和制热能力，但若L3的取值过小，则不能起到支撑所述蒸发器翅片的作用，不能有效地避免所述尖角11划破所述防水层31而造成的漏水问题。
在一些可选实施例中，如图8所示，所述凸起311的底面距离所述接水装置3的底面的尺寸为b，所述集水槽的底面距离所述接水装置的底 面的尺寸为c，则b比c大2-5mm，在这个范围内，将使得所述接水装置具有相对好的排水性能，并且能够兼顾到所述空调室内机性能不受影响。
高度差越大，则所述集水槽33的排水速度越快，不会造成冷凝器吹水的现象，若高度差越小，排水速度越慢，且存在冷凝水不能及时排出后，出现吹水的问题。
本发明实施例在所述接水装置的两端设置了所述第一排水嘴34和所述第二排水嘴35，并将所述排水面325设置为倾斜方向，不同横截面上高度不同，当空调室内机制冷时，可使得蒸发器产生的冷凝水聚集到所述接水装置中后，冷凝水从高到低进行流动，采用自然排水方法，通过所述第一排水嘴34流出所述排水装置。
当然，也可以根据客户的需要，采用水泵的作用，使得冷凝水从所述第二排水嘴35中排出，本发明实施例具有双向排水功能，即自然排水和使用水泵排水，可满足不同方位需求的安装要求。
为了使冷凝水更加集中，设置了所述集水槽33，可使得冷凝水更加方便的排出所述接水装置3。
本发明实施例将使得更换压缩机更加便捷，避免了压缩机螺栓和所述接水装置3之间的垂直度偏差。
根据本发明实施例的第二方面，提供了一种空调室内机，所述空调室内机具有上面提到的所述接水装置3。
本发明并不局限于上面已经描述并在附图中示出的结构，并且可以在不脱离其范围进行各种修改和改变。本发明的范围仅由所附的权利要求来限制。
