首先参阅图1和2，其中，图1是本发明的空调器的部分结构示意图，图2是本发明的喷淋构件和驱动构件的结构示意图。如图1和2所示，所述空调器包括冷媒循环回路(图中未示出)以及设置在所述冷媒循环回路上的室外换热器11和室内换热器21，所述空调器还包括喷淋构件12、驱动构件13、储水构件22和动力装置23，储水构件22设置成能够接收室内换热器21在换热过程中产生的冷凝水；驱动构件13设置成能够驱动喷淋构件12相对于室外换热器11移动以实现移动喷淋；喷淋构件12和储水构件22相连，动力装置23设置成能够驱动储水构件22中的水通过喷淋构件12喷淋至室外换热器11上。
具体而言，以图1所示方向为基准方向，所述空调器包括室外机1和室内机2，室外机1内设置有室外换热器11，室内机2内设置有室内换热器21，室外换热器11和室内换热器21通过所述冷媒循环回路相连通，喷淋构件12设置有三个，每个喷淋构件12均连接有驱动构件13，驱动构件13和室外换热器11相连，左侧的喷淋构件12和中间的喷淋构件12通过连接软管14相连，中间的喷淋构件12和右侧的喷淋构件12通过连接软管14相连，室内机2内设置有储水构件22，储水构件22能够接收室内换热器21在换热过程中所产生的冷凝水并将冷凝水进行储存，室内机2内还设置有动力装置23，动力装置23和储水构件22相连通，且动力装置23和左侧的喷淋构件12相连通。
所述空调器进入除尘工作模式时，动力装置23驱动储水构件22内的冷凝水流至三个喷淋构件12内，三个驱动构件13同时驱动三个喷淋构件12相对于室外换热器11同步移动，以实现对室外换热器11的喷淋清洗，实现除尘降温的目的。
接下来参阅图2，以图2所示方向为基准方向，喷淋构件12上设置有多个喷嘴121，驱动构件13为直线电机，所述直线电机能够驱动喷淋构件12上下移动，实现对室外换热器11的喷淋清洗。
需要说明的是，本发明不对喷淋构件12的具体结构作任何 限制，例如，喷淋构件12的数量为一个，其形状为U形管状结构，以适应室外换热器11，此时，仅仅设置一个驱动构件13即可，本领域技术人员可根据实际情况自行设定。
另外，需要说明的是，本发明不对驱动构件13的具体结构和具体设置方式作任何限制，例如，驱动构件13为液压缸和推杆，所述液压缸和所述推杆相连且能够驱动所述推杆移动，所述推杆和喷淋构件12垂直相连，基于此，所述液压缸驱动所述推杆上下移动进而实现喷淋构件12的上下移动；还可以是，驱动构件13设置成能够驱动喷淋构件12左右移动对室外换热器11进行喷淋清洗，本领域技术人员可根据实际情况自行设定。
进一步地，所述空调器包括控制器24，控制器24设置成能够控制动力装置23、喷淋构件12和驱动构件13进行工作。本领域技术人员能够理解的是，本发明不对控制器24的具体结构和型号作任何限制，并且控制器24既可以是所述空调器原有的控制器，也可以是为执行本发明的除尘控制方法单独设置的控制器，本领域技术人员可以根据实际使用需求自行设定控制器24的结构和型号。
基于上述结构设置就能够解决空调器难以自动对室外换热器进行除尘降温影响空调器的制冷效果的问题，并且本发明还结合以下除尘控制方法对进行储水构件22、动力装置23、喷淋构件12和驱动构件13进行及时准确的调控。
接下来参阅图3，图3是本发明的除尘控制方法的主要步骤流程图。如图3所示，基于上述实例中所述的空调器，本发明的除尘控制方法包括：
S1：获取室外换热器所处环境的温度；
S2：根据室外换热器所处环境的温度，选择性地控制喷淋构件开启。
进一步地，在步骤S1中，室外机1内设置有第一温度传感器15，第一温度传感器15靠近室外换热器11设置，能够检测室外换热器11所处环境的温度，并将温度以信号形式传输至控制器24，在一种优选实施例中，第一温度传感器15能够获取室外换热器11所处环境的实 时温度，在另一种优选实施例中，第一温度传感器15能够获取室外换热器11所处环境的日均温度。
进一步地，在步骤S2中，在一种优选实施例中，如果室外换热器11所处环境的某一时间的温度在不预设范围内，证明此时环境温度高，需要对室外换热器11进行降温，则控制器24控制喷淋构件12开启，对室外换热器11进行喷淋降温；在另一种优选实施例中，如果室外换热器11所处环境的日均温度在预设天数内均大于预设温度，则控制器24控制喷淋构件12开启，对室外换热器11进行喷淋除尘。
接下来参阅图4，图4是本发明的除尘控制方法的优选实施例的具体步骤流程图。如图4所示，基于上述实施例中所述的空调器，本发明的除尘控制方法的优选实施例具体包括下列步骤：
S101：分别获取预设天数中室外换热器所在环境的日均温度；
S102：如果预设天数中获取到的室外换热器所在环境的日均温度均大于第一预设温度；
S103：在空调器运行制冷模式的情形下，控制储水构件接收室内换热器所产生的冷凝水；
S104：获取以预设天数之后为起始时间至今期间空调器在制冷模式下的第一累计运行时间；
S105：如果第一累计运行时间大于或等于第一预设时间，则控制动力装置和喷淋构件均开启；
S106：经过第二预设时间后，控制动力装置和喷淋构件关闭；
S107：从动力装置和喷淋构件关闭的时刻开始计时，空调器在制冷模式下累计运行第三预设时间后，则控制动力装置和喷淋构件再次开启。
进一步地，在步骤S101中，通过第一温度传感器15获取3天中室外换热器11所在环境的日均温度，并将每天的室外换热器11所在环境的日均温度以信号的形式传输至控制器24；还可以是，第一温度传感器15每间隔一个小时获取室外换热器11所在环境的温度，并传输至控制器24，控制器24对同一天中第一温度传感器15获取的多个温度数 据取中间值或是平均数作为本天中的日均温度，本领域技术人员可根据实际情况自行设定。
需要说明的是，本发明不对所述预设天数的具体数值作任何限制，本领域技术人员可根据实际情况自行设定。
进一步地，在步骤S102中，如果3天中获取到的室外换热器11所在环境的日均温度均大于25℃，则控制器24判定季节为夏季，在冬季时，室外换热器11能够进行结霜和化霜功能，能够起到清洗除尘的作用，在夏季时，室外换热器11难以自动进行除尘，控制器24判断季节为夏季后，方便控制器24控制喷淋构件12进行喷淋除尘和降温；需要说明的是，本发明不对第一预设温度的具体数值作任何限制，例如，例如第一预设温度为26℃-29℃均可，本领域技术人员可根据实际情况自行设定。
进一步地，在步骤S103中，在所述空调器运行制冷模式的情形下，控制器24控制储水构件22接收室内换热器21所产生的冷凝水；在制冷模式下，室内换热器21会产生冷凝水，在控制器24判断季节为夏季时，利用储水构件22收集冷凝水，可供喷淋构件12喷淋使用。
进一步地，在步骤S104中，通过控制器24获取以第三天之后为起始时间至今期间所述空调器在制冷模式下的第一累计运行时间，例如，第四天所述空调器在制冷模式下运行5小时，控制器24记录第四天的数据5小时，第五天所述空调器在制冷模式下运行10小时，控制器24记录第五天的累计数据为15小时，第六天所述空调器在制冷模式下运行5小时，则控制器24记录第六天的累计数据为20小时，依次类推，获取所述第一累计运行时间。
进一步地，在步骤S105中，如果所述第一累计运行时间大于或等于第一预设时间，则控制动力装置23和喷淋构件12均开启，具体而言，第一预设时间为80小时，如果所述第一累计运行时间大于或等于80小时，此时储水构件22内接收了一定量的冷凝水，能够满足喷淋构件12对室外换热器11的一次喷淋使用，则控制器24控制动力装置23将储水构件22内的冷凝水引至喷淋构件12，通过喷嘴121喷淋至室外换热器11的表面，同时控制器24控制驱动构件13驱动喷淋构件12相对 于室外换热器11移动，以对室外换热器11进行全面的喷淋除尘。
需要说明的是，本发明不对第一预设时间的具体数值作任何限制，本领域技术人员可根据实际情况自行设定。
进一步地，在步骤S106中，经过第二预设时间后，控制动力装置23和喷淋构件12关闭，经过2分钟后，控制器24控制动力装置23和喷淋构件12关闭，此时结束对室外换热器11的喷淋除尘，避免储水构件22中的水被喷淋尽使得喷嘴121空喷，避免损坏连接软管14以及其它供水管路。
需要说明的是，本发明不对第二预设时间的具体数值作任何限制，本领域技术人员可根据实际情况自行设定。
进一步地，在步骤S107中，从动力装置23和喷淋构件12关闭的时刻开始计时，所述空调器在制冷模式下累计运行第三预设时间后，则控制动力装置23和喷淋构件12再次开启，此时储水构件22内重新接收了一定量的冷凝水，能够满足喷淋构件12的一次喷淋使用，所述第三预设时间和所述第一预设时间相等，当然，可以理解的是，还可以是，所述第三预设时间大于所述第一预设时间，本领域技术人员可根据实际情况自行设定，步骤S107的设置，使得所述空调器能够定期对室外换热器11进行除尘。
此外，在本优选实施例中，所述除尘控制方法还包括以下步骤：
获取室外换热器11的冷媒进口处的温度；
如果室外换热器11的冷媒进口处的温度大于第二预设温度，则控制喷淋构件12开启。
具体而言，在室外换热器11的冷媒进口处设置有第二温度传感器16，，所述冷媒进口为现有技术中室外换热器11原有的冷媒进口，第二温度传感器16将检测的温度传输至控制器24，如果检测到的温度大于80℃，此时证明室外换热器11的温度过高，控制器24控制喷淋构件12开启，对室外换热器11进行喷淋降温，喷淋一段时间后，控制器24控制喷淋构件12关闭，从喷淋构件12关闭后进入步骤S103。
进一步地，所述除尘控制方法还包括以下步骤：
获取室外换热器11所处环境的温度；如果室外换热器11所处环境的温度大于第三预设温度，则控制喷淋构件12开启。其中，所述第三预设温度大于所述第一预设温度。
具体而言，如果第一温度传感器15所检测到温度大于65℃，则控制器24控制喷淋构件12开启对室外换热器11进行喷淋降温。
在另一种可行的实施例中，在执行步骤S103的期间，所述除尘控制方法还包括：
获取储水构件22内的水位；
如果储水构件22内的水位高于或等于预设水位，则控制动力装置23和喷淋构件12均开启；
如果储水构件22内的水位低于所述预设水位，则不控制动力装置23开启。
具体而言，储水构件22内设置有水位传感器221，如果水位传感器检测到储水构件22内的水位高于或等于所述预设水位，证明储水构件22即将储满水，为了避免水溢出储水构件22，控制器24控制动力装置23和喷淋构件12开启，以对室外换热器11进行除尘降温；如果水位传感器检测到储水构件22内的水位低于所述预设水位，则证明储水构件22内收集的冷凝水的量不能够满足喷淋构件12一次喷淋使用，为了保证喷淋构件12的喷淋除尘效果，所以，只要是储水构件22内的水位低于所述预设水位，控制器24控制动力装置23始终处于关闭状态；在上述情形下，可将喷淋构件12和储水箱(图中未示出)相连通，所述储水箱连接有泵装置(图中未示出)，所述泵装置提供喷淋压力，所述储水箱内的水能够满足喷淋构件12多次喷淋使用，所述储水箱可设置在室内，方便用户向所述储水箱内加水。
在上述任意一种优选实施中所述的空调器均包括所述储水箱和所述泵装置，在储水构件22内的水不能够满足喷淋构件12一次喷淋使用时，喷淋构件12能够利用所述储水箱内的水进行喷淋除尘和喷淋降温。
至此，已经结合附图所示的优选实施方式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，本发明的保护范围显然 不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
