具体实施方式
为使本公开的上述目的、特征和优点能够更为明显易懂，下面结合附图对本公开的具体实施例做详细的说明。
如图1-3所示，本公开实施例提供一种过滤网清洗装置及包含其的空调器，所述过滤网清洗装置包括蒸发器部件和加水装置，所述蒸发器部件包括依次连接的蒸发器上支架2、蒸发器和接水盘1；所述加水装置用于抽取所述接水盘1收集的冷凝水，并将所述冷凝水传输至所述蒸发器上支架2，可实现冷凝水的再利用；所述蒸发器上支架2设有多个冷凝水出水口3，所述出水口3沿所述蒸发器上支架2的延伸方向分布，可选地，所述出水口3可沿所述蒸发器上支架2的延伸方向均匀分布，用以流出冷凝水，利用冷凝水从蒸发器上支架2流出实现对过滤网7的进行清洁。
本公开实施例提供的空调器的过滤网7固定于所述蒸发器上支架2与所述接水盘1之间，环绕所述蒸发器设置，因此当所述蒸发器上支架2的出水口3流出冷凝水后，冷凝水可以直接流经所述过滤网7，相比从水泵出水管直接喷洒过滤网，可避免因水流冲击而将冷凝水溅射出来的现象。另一方面，所述出水口3沿所述蒸发器上支架2的延伸方向均匀分布，可以保证流出的冷凝水全面覆盖过滤网7，实现过滤网7的全面清洗。
具体的，如图4所示，所述加水装置包括水泵4、进水管5和出水管6，所述进水管5连接所述接水盘1，所述出水管6连接所述出水口3。可选地，所述水泵4设置在所述蒸发器上支架2之上。所述出水管6包括水平管61和管口朝下的竖直管62，所述出水管6设置为1个或多个，可选为1个；所述出水口3可设置在所述蒸发器上支架2的底部或侧壁，可选为侧壁；多个出水管6可直接连通到出水口3或者连通在蒸发器上支架2的凹槽内，因此 使得出水管6排出的冷凝水可以从出水口3流出。
可选地，所述接水盘1包括冷凝水收集部和冷凝水排出部，所述进水管5连接所述冷凝水收集部，所述冷凝水收集部收集蒸发器产生的冷凝水。为了避免清洗完过滤网7的冷凝水直接从空调溢出，因此设置所述出水口3喷出的冷凝水由接水盘1的所述冷凝水排出部利用排水管排出。
可选地，所述过滤网7为圆弧形结构，所述接水盘1及蒸发器上支架2的形状与所述滤网7的形状相适配，可实现过滤网7环绕所述蒸发器并设置在蒸发器部件的接水盘1及蒸发器上支架2之间。
基于以上，本公开实施例提供的过滤网清洗装置通过空调自身产生的冷凝水对过滤网进行清洗，实现冷凝水的再利用，不需要引入额外的水资源，实现过滤网的自动清洗，进而提高了用户使用的舒适度；直接利用出水口引出的冷凝水对过滤网进行清洗，结构简单、易于实现。
虽然本公开披露如上，但本公开并非限定于此。任何本领域技术人员，在不脱离本公开的精神和范围内，均可作各种更动与修改，因此本公开的保护范围应当以权利要求所限定的范围为准。
