如图1所示，本实施例的空调回风的除尘控制方法，包括以下步骤：
1)在空调启动或者正常运行时，检测室内空气的PM2.5实际浓度值X；
2)将检测到的室内空气PM2.5实际浓度值X与预设值X1进行比较，当X≥X1时，即表示室内空气较污浊，此时启动空调回风管路中的静电除尘过滤箱13，回风则经过静电除尘过滤箱13进行除尘；当室内空气经过一定时间的除尘后，PM2.5浓度值下降，当低于预设值时，即表示室内空气较干净，此时回风则不经过除尘处理，从而达到自动净化室内空气的效果。本发明的方法将检测到的室内空气PM2.5浓度值X与预设值X1进行比较，然后根据比较结果来控制空调回风管路中的静电除尘过滤箱13的启闭，从而实现对室内的空气进行自动除尘的目的，操作方便、节能环保。
本实施例中，静电除尘过滤箱13为可用水清洗的静电除尘过滤箱，当X＜X1时，可关闭静电除尘过滤箱13，且设置避让管路使回风通过避让通道而不经过静电除尘过滤箱13，从而使回风不经过除尘处理；此时可以对静电除尘过滤箱13中的静电除尘组件1302进行水清洗。在其它实施例中，当X＜X1时，即不需要对室内空气进行静电除尘时，可关闭静电除尘过滤箱13中的静电除尘组件1302，此时回风仍然经过静电除尘过滤箱13，但是没有除尘功能。
本实施例中，步骤2)中的预设值X1为75ug，可根据实际情况进行适当调整。
本实施例中，在步骤1)中，通过PM2.5检测仪检测室内空气的PM2.5实际浓度值X，PM2.5检测仪型号为JSA2-PM2.5(深圳吉顺安科技有限公司)，可安装在室内任一位置，也可以安装在空调内机1上。
本发明还公开了一种除尘空调，其具体实施例一为：如图2至图4所示，本实施例的除尘空调，包括空调内机1、空调外机2以及凝水管，空调内机1与空调外机2通过冷媒管路连通，空调内机1上设置有回风口11与送风口12，送风口12处设置有将空气从回风口11导入送风口12的风机14，还包括用于检测室内空气PM2.5浓度的检测件4、设置在空调内机1内部的可用水清洗的静电除尘过滤箱13、以及根据室内PM2.5浓度控制静电除 尘过滤箱13电源通断的控制器5，检测件4、静电除尘过滤箱13均与控制器5电连接，静电除尘过滤箱13位于连通回风口11与送风口12的一回风管路上。检测件4检测室内空气的PM2.5实际浓度值X并传递给控制器5，控制器5将X与预设值X1进行比较，当X≥X1时，则表示空气较污浊，则启动静电除尘过滤箱13的电源，对经过的回风进行自动除尘；当X＜X1时，表示室内空气较干净，则关闭静电除尘过滤箱13的电源，回风经过静电除尘过滤箱13后则没有经过静电除尘处理。本发明的除尘空调通过对室内空气PM2.5的检测，实现室内空气的自动除尘。另外静电除尘过滤箱13上设置有进水管1309和排水管1310，以方便与外部管路连通。
本实施例中，检测件4为PM2.5检测仪，其型号为JSA2-PM2.5(深圳吉顺安科技有限公司)，可安装在室内任一位置，也可以安装在空调内机1上；控制器5为可编程控制器。
本实施例中，回风口11与静电除尘过滤箱13之间的回风管路上设置有三通电磁切换阀3，三通电磁切换阀3与控制器5电连接，三通电磁切换阀3的进口与回风口11连通，三通电磁切换阀3的其中一个出口与静电除尘过滤箱13的进风腔1304连通，另一个出口通过一直通管路与风机14连通。当当X＜X1时即判断室内空气较干净，将三通电磁切换阀3的进口与风机14相连通，回风则不经过静电除尘过滤箱13而直接送至送风口12；当X≥X1时，即判断室内空气污浊，将三通电磁切换阀3的进口与静电除尘过滤箱13的进风腔1304连通，回风则经过静电除尘过滤箱13除尘后送回至室内，通过对室内PM2.5指数的监测，能够判断室内空气洁净程度、从而判断回风是否需要静电除尘，操作简单、方便使用且节能环保。
本实施例中，静电除尘过滤箱13采用喷淋式水清洗方式，其具体结构包括箱体1301和静电除尘组件1302，静电除尘组件1302将箱体1301内腔分隔为进风腔1304和出风腔1305，进风腔1304和/或出风腔1305内设有朝向静电除尘组件1302的喷淋组件1303，其中进水管1309的一端与喷淋组件1303连通，另一端与室内的自来水管连通，而排水管1310则连通至空调的凝水管；当需要对静电除尘组件1302进行清洗时，首先停止空调的运行，然后带水压的自来水经进水管1309进入喷淋组件1303，对静电除尘组件1302进行喷淋清洗，清洗完后的污水则经排水管1310流至凝水管后排出室外，本实施例中的进风腔1304和出风腔1305均设有朝向静电除尘组件1302的喷淋组件1303；因此本发明的静电除尘过滤箱13的进水取用方便，且污水则通过凝水管直接排出，从而能够大大减少管路的布置，且易于实现。在其它实施例中，进水管1309的一端与喷淋组件1303连通，另一端与一带高压水泵的水箱连通，同样能够实现喷淋清洗的目的。
实施例二：
本实施例中与实施例一的区别仅在于静电除尘过滤箱13采用贮水清洗方式，如图5至图6所示，其具体结构包括箱体1301，箱体1301包括上部分隔的进风腔1304和出风腔1305，进风腔1304的下部与出风腔1305的下部连通，形成贯穿风道，进风腔1304的一侧设置有吸风口1306，出风腔1305的顶部设置有排风口1307，出风腔1305内安装有静电除尘组件1302，静电除尘组件1302至少一侧设置有超声波震板1308，本实施例中静电除尘组件1302的两侧均设置有超声波震板1308，其中进水管1309安装在进风腔1304的一侧且与自来水管连通，在其它实施例中，进水管1309也可以与一带高压水泵的水箱连接，排水管1310安装在箱体1301的底部且与凝水管相连；当需要对静电除尘组件1302进行清洗时，自来水经进水管1309进入箱体1301内并将静电除尘组件1302浸泡，然后启动超声波震板1308，超声波震板1308发射超声波并通过水介质产生的空化效应，将静电除尘组件1302上的积尘剥离，达到彻底清洗的目的，当清洗完成后，关闭超声波发生器，打开排水管1310，污水则经排水管1310流至凝水管内排至室外。其它内容与实施例一相同，在此不再赘述。
虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明。任何熟悉本领域的技术人员，在不脱离本发明技术方案范围的情况下，都可利用上述揭示的技术内容对本发明技术方案做出许多可能的变动和修饰，或修改为等同变化的等效实施例。因此，凡是未脱离本发明技术方案的内容，依据本发明技术实质对以上实施例所做的任何简单修改、等同变化及修饰，均应落在本发明技术方案保护的范围内。
