本申请涉及空气处理相关技术领域，特别是一种空气处理装置及控制方法。
背景技术
公开号为CN106482271A的专利公开了一种加湿器的紫外除菌方法，但是这种方法只是针对加湿器开机运行时的除菌，而根据深紫外发生器的特性，例如LED紫外杀菌灯，光电转化率仅有不到5％，也就是说大量的电能变成热量散发出来，同时大量的热能也会损害紫外灯的寿命。由此可见，深紫外发生器不能长时间点亮，通常行业的做法是间歇性工作，这种做法可以有效保护紫外灯，但对于加湿器这种缓慢流速的水杀菌效果有限。

参考图1-3所示，本申请提供一种空气处理装置，例如加湿器，包括水箱组件2、水槽1和除菌装置5，所述除菌装置5包括除菌部51，例如除菌部为紫外灯，所述除菌部51设置在所述水槽1中，所述水箱组件2与所述水槽1之间设置有补水开关21，所述补水开关21用于控制所述水箱组件2与所述水槽1之间的通断，所述空气处理装置还包括控制部8，所述控制部8能够根据所述补水开关21的开关状态控制所述除菌部51的开闭，例如，当补水开关21打开时，除菌部51便打开，进行除菌，可有效对补充水进行除菌，解决补充水带来的水槽1内的水的二次污染问题。
参考图1-3所示，该加湿器还设置有集雾结构4、雾化器7、风机6和出雾通道22， 集雾结构4形成集雾空间42，雾化器7位于集雾空间42内，风机6的出风口与集雾空间42连通，集雾空间42与出雾通道22连通，雾化器7产生的水雾在集雾空间42内聚集，风机6产生的风被送到集雾空间42内，风将水雾沿着出雾通道22排出加湿器，实现加湿效果。
参考图1-3所示，除菌部51至少部分位于集雾空间42内，优选全部位于集雾空间42内，以对集雾空间42内的水和水雾进行除菌处理，例如除菌部51为紫外灯，除菌装置5包括紫外光源和灯罩，紫外光源位于灯罩内，例如紫外光源为汞灯，通过灯罩将汞灯和集雾空间42内的水和水雾隔离，避免汞灯与水或者水雾直接接触，降低汞灯由于骤冷骤热容易损坏的可能性。通过紫外灯对水和水雾的杀菌作用，保证加湿器排出的水雾是健康的，避免由于带有细菌的水雾中被吸入肺部危害健康，造成用户的身体不适，为用户提供一个良好的生活空间。
优选地，参考图1-3所示，除菌装置5和雾化器7设置在水槽1底部，集雾结构4罩在除菌部51和雾化器7的上方，并将雾化器7和除菌部51罩设在集雾空间42内，除菌装置5靠近雾化器7设置，例如除菌部51位于雾化器7的边缘位置，以保证灯光能够很好地照射到雾化器7内的水，也能更好地实现对雾化器7产生的水雾进行杀菌。另外，除菌部51可以为半球状的LED灯、U形的紫外灯、柱状的紫外灯等，除菌部可以竖向放置，也可以横向放置，优选除菌部51竖向防止，构造为竖向延伸的柱状结构，优选为圆柱形结构，以方便加工制作，即，除菌部51由水槽1的槽底沿水雾向外流动的方向延伸，可更好地保证灯光能很好地照射集雾空间42的各个角落，起到更好地杀菌效果。
集雾结构4例如构造为筒形结构，所述筒形结构的内部构成集雾空间42，雾化器7至少部分结构位于筒状结构内，优选全部位于筒状结构内，以确保雾化器7的产生的水雾全部进入集雾空间42，然后通过出雾通道22排出加湿器，保证加湿效果，或者，参考图1-3所示，集雾结构4包括构造为弯曲或弯折的板状结构41，优选所述板状结构41设置有两个，两个所述板状结构41构造为朝向同一侧的弯折的集雾结构4，雾化器7至少部分结构位于两个板状结构41之间，两个所述板状结构41之间形成集雾空间42，或者，加湿器的水槽1的侧壁或其他与所述集雾结构4配合的结构构成在周向上闭合的集雾空间42，所述集雾空间42使得水雾不会扩散到外部，并通过出风口吹出的风使水雾流向所述出雾通道22。本实施例中采用两个板状结构41构成上述的集雾空间42，结构简单，方便加工制作。需要说明的是，集雾结构4并不局限与上述的结构，只要可以在水槽1内围成一个相对封闭的区域即可，可以是环状包围，也可以是半环状与水槽1的侧壁配合形成相对封闭区域，同样可以是异形复杂形状，只要能形成封闭即可。
参考图1-3所示，出雾通道22位于水箱组件2中，连通集雾空间42和加湿器的外部，以使得水雾能够通过出雾通道22排出加湿器，另外，集雾结构4与水箱组件2通过卡扣连接，或者通过紧固件连接，或者粘接连接，或者焊接连接，再或者，集雾结构4与水箱组件2为一体成型结构，以更好的确保集雾结构4与水箱组件2组成的整体的结构强度和稳定性，确保集雾空间42的密封性，避免水雾从集雾结构4与水箱组件2的交界处泄漏。
该加湿器还包括用于检测所述水槽1内的水位的水位检测装置11，参考图1-3所示，所述控制部8能够根据所述水位检测装置11检测的水位控制所述补水开关21的开关状态，例如，当水槽1内的水位低于设定值时，控制部8控制补水开关21打开，对水槽1进行补水，以确保加湿效果。
具体的，参考图1-3所示，补水开关21包括下水阀211和电磁阀212，所述电磁阀212与所述控制部8相连，所述控制部8能够控制所述电磁阀212带动所述下水阀211的动作，以实现所述水箱组件2与所述水槽1之间的连通或断开，结构简单、可靠。需要说明的是，补水开关21也可以通过磁铁、水泵等其他结构形式实现补水功能。
本申请还提出保护一种空气处理装置的控制方法，例如上述加湿器的控制方法包括：至少根据所述补水开关21的开关状态控制所述除菌部51的开闭，即，该控制方法中，补水开关21与除菌装置5可联动控制，以实现的更好的除菌效果。另外，当所述水箱组件2与所述水槽1处于分离状态时，控制部8控制所述除菌装置5关闭，例如在水箱组件2与水槽1的连接处设置传感器(图中未示出)，通过传感器检测水箱组件2和水槽1是否分离，进而控制紫外灯关闭，避免提起水箱组件2时紫外灯对用户造成伤害。
参考图1-3所示，所述加湿器的控制方法包括开机控制过程和常规控制过程，开机控制过程即加湿器由开机至进入常规控制过程之间的控制过程，在开机控制过程中，当加湿器由关机状态变换为开机状态时，水位检测装置11检测水槽1内的液位，若水槽1内的液位未达到设定值，则控制所述补水开关21打开，直至所述水槽1内的液位达到所述设定值时，控制所述补水开关21关闭，并同时控制紫外灯打开，并持续预定时长后关闭，进入常规运行控制过程，预定时长为0-10min,例如3min，实现对进入的第一股水流的除菌，确保第一股水流的无菌；若所述水槽1内的液位高于或等于所述设定值，则直接控制紫外灯打开，持续3min,然后进入所述常规运行控制过程。另外，在开机控制过程中，如果水槽1内水量过少，雾化器7工作可能会造成雾化器7的损坏，也浪费电源，因此优选开机控制过程中雾化器7处于关闭状态，并且，如果开机时水槽1内的水位没有达到设定值，则需要补水，此时紫外灯处于关闭状态，如果雾化器7工作，容易将带细菌的水雾喷出，影响用户的身体健康。
在常规运行控制过程中，参考图1-3所示，雾化器7处于开启状态，以为用户提供加湿用的水雾。当所述水槽1处于补水状态时，即，水位检测装置11检测到水槽1内的水位低于设定值，所述补水开关21处于打开状态，控制部8控制所述除菌部51处于持续工作状态，以对补充水进行杀菌作用，保证新补充的水被有效杀菌，有效避免因水分子布朗运动造成的水槽1的水二次污染的问题；当所述水槽1处于正常水量状态时，即，水位检测装置11检测到水槽1内的水位等于或高于设定值，所述补水开关21处于关闭状态，控制部8控制所述除菌部51处于间歇工作状态，例如除菌部51每隔第一时长工作第二时长，第一时长为0-5min，第二时长为0-5min,例如第一时长为50秒，第二时长为10秒，既能保证实时杀菌，同时能够良好散热。
需要说明的是，由于加湿器在关机状态时水槽中的水滋生细菌的可能性比较大，因此优选预定时长大于第二时长，以更好的杀死水槽中的细菌，避免加湿器刚开机时喷出的水雾中带有细菌。
在一个具体实施例中，参考图1-3所示，加湿器包括水箱组件2和底座3，其中底座3上设有安装各类元器件和盛放直接雾化用水的水槽1。水箱组件2上设有下水阀组件(即补水开关21)，包括下水阀211和电磁阀212，当水槽1水位低于设定水位时进行补水，下水阀211对应的水槽1上装有电磁阀212，通电后可顶起下水阀211实现补水功能。在水箱组件2上还装有集雾结构4，集雾结构4通过卡扣连接在水箱组件2上(也可以和水箱组件2一体成型)。水槽1上装有雾化器7，用于将水打成水雾，快速加湿。在雾化器7旁边装有紫外灯，水箱组件2放置到位后，集雾结构4罩在雾化器7和紫外灯上方，此时水槽1中的水优选没过集雾结构4与水槽1之间的间隙，形成一个相对封闭的集雾空间42，用于杀菌。当加湿器运行时，用于直接雾化的水聚集在雾化器7上方，紫外灯点亮工作照射此范围内的水进行杀菌。由于紫外线的穿透能力差，故所有能量均聚集在集雾结构4围成的集雾空间42内，能量损耗小。同时由于紫外灯距离雾化器7很近，紫外灯可以照射到雾化器7上方的各个角落，对于水槽1内的水有良好的杀菌效果，避免开机后的第一股水雾携带细菌喷出，采用这种结构的紫外杀菌加湿器，可以确保每一滴水在被雾化前经过紫外线照射杀菌，没有二次污染，加湿更健康。此外，本申请中的水槽1结构简单，生产制造效率高，用户取下水箱组件2后也可便捷的清洗水槽1。加湿器通电开机后，浮子检测板结构(即水位检测装置11)用于检测水槽1水位，包括浮子111和检测板112，当水位未达到设定值时，开启电磁阀212推动下水阀211打开补水，当水槽1水位达到设定值后，关闭下水阀211，点亮紫外灯照射预定时长，例如3min,实现集雾空间42内的水的长效杀菌，然后雾化器7开始工作，形成水雾，由风机6带动吹出加湿器，实现加湿功能。 在正常运转期间(即水槽1水量充足无需补水时)，紫外灯间歇性工作，例如每隔50秒点亮10秒，实时杀菌，同时能够良好散热。当水槽1水位消耗后低于设定值时，开启下水阀211补水，同时点亮紫外灯进行杀菌，保证新补充的水被有效杀菌，有效避免因水分子布朗运动造成的水槽1的水二次污染问题。另外，该加湿器通过浮子111和检测板112的配合实现提起水箱组件2时对紫外灯的控制，例如，在加湿器运行期间若水箱组件2被提起，浮子111随水箱组件2离开检测板112位置，检测板112断开，紫外灯立即熄灭，以免用户受到紫外照射伤害，需要说明的是，上述的紫外灯、检测板112、电磁阀212均与控制部8电连接，以实现联动控制。
上述加湿器中，由于采用了将紫外灯放置在雾化器7附近，紫外灯与集雾结构4配合形成局部杀菌空间的方式，使得紫外灯的能量相对集中，杀菌效果好，同时，紫外光可近距离照射直接雾化用水，杀菌更彻底，同时解决水槽1内的水容易滋生细菌的问题，用户在使用过程中拿起水箱组件2即可清洗水槽1的各个角落，并且，紫外灯和加湿器下水阀211组件联动，在加湿器通过水箱组件2给水槽1补水的同时开启紫外灯杀菌，彻底解决新补充水带来的二次污染问题，为用户提供更好的使用体验。
本领域的技术人员容易理解的是，在不冲突的前提下，上述各优选方案可以自由地组合、叠加。
应当理解，上述的实施方式仅是示例性的，而非限制性的，在不偏离本申请的基本原理的情况下，本领域的技术人员可以针对上述细节做出的各种明显的或等同的修改或替换，都将包含于本申请的权利要求范围内。
