本申请提出一种空气处理模块。
在本申请实施例中，如图1至图9所示，该空气处理模块包括：壳体10，设有第一进风口11、出风口12、排风口13、内循环风道14和排风风道15，所述内循环风道14连通所述第一进风口11与所述出风口12，所述排风风道15连通所述内循环风道14与所述排风口13；风机20，设于所述内循环风道14，所述风机20的进风侧对应所述第一进风口11，所述风机20的出风侧对应所述出风口12和所述排风风道15；第一风门30，用以选择性地将所述出风口12或排风风道15与所述内循环风道14导通。
在本实施例中，第一进风口11和出风口12与室内连通，排风口13通过穿墙孔与室外空气连通，室内空气从第一进风口11进入内循环风道14后，可从出风口12吹出，也可流向排风风道15后从排风口13吹出。第一进风口11可开设于壳体10的顶部，出风口12可开设于壳体10的前面板，排风口13可开设于壳体10的背板，由此可使空气处理模块形成顶部进风，正面出风，背部排风的气流流路。风机20的种类不做限制，只需满足进风侧与第一进风口11对应，出风侧与出风口12和排风风道15对应即可。第一风门30可活动安装于壳体10，第一风门30的活动方式不做限制，只需满足可选择性地将出风口12或排风风道15与内循环风道14导通即可。也就是说，第一风门30在将内循环风道14与出风口12导通的同时会将内循环风道14与排风风道15阻断，在将内循环风道14与排风风道15导通的同时会将内循环风道14与出风口12阻断。由此，通过第一风门30控制内循环风道14与出风口12和排风风道15的切换导通，可实现空调室内机的内循环模式和排风模式。
在内循环模式，第一风门30将内循环风道14与出风口12导通，空气从第一进风口11进入内循环风道14，沿内循环风道14流向出风口12，以实现室内气流循环流动。具体地，所述空气处理模块还包括设于所述第一进风口11处的净化组件100。净化组件100用以净化流经第一进风口11的空气，具体具有除甲醛、杀菌、除尘、消毒、除臭氧等功能中的一种或多种。在内循环模式，净化组件100可提高出风气流的洁净度。
在排风模式，第一风门30将内循环风道14于排风风道15导通，空气从第一进风口11进入内循环风道14，沿内循环风道14流向排风风道15，最终流出排风口13，以将室内的污风排出，实现室内空气的更新。结合上述净化组件100的实施例，净化组件100会对流经第一进风口11的气流形成阻力，而排风模式的气流可以不用被净化，因此，在实际应用中，所述壳体10还开设有与所述内循环风道14连通的第二进风口16，所述空气处理模块还包括用以打开或关闭所述第二进风口16的第四风门90。在排风模式，第四风门90可打开第二进风口16，由于第二出风口12没有设置净化组件100，阻力更小，因此气流能更多更快地流入内循环风道14，以提高排风效率。而在内循环模式，第四风门90可关闭第二进风口16，以使气流能全部流经净化组件100，提高洁净度。
本申请空气处理模块在壳体10内形成相连通的内循环风道14和排风风道15，并通过第一风门30选择性地将内循环风道14与出风口12或排风风道15连通，从而可内循环风道14和内循环风道14内的风机20既可用以实现内循环功能、又可用以实现排风功能，简化了空调室内机的内部结构。
如图2至图5所示，所述空气处理模块还包括蜗壳40和风道壳50，所述蜗壳40的进风端与所述第一进风口11连通，所述风机20设于所述蜗壳40内；所述风道壳50形成所述排风风道15，所述风道壳50与所述蜗壳40连接，所述第一风门30设于所述出风口12与所述风道壳50之间，所述第一风门30与所述风道壳50之间形成过流间隙51，所述过流间隙51连通所述蜗壳40与所述排风风道15，所述第一风门30用以选择性地将所述出风口12或过流间隙51与所述内循环风道14导通。
在本实施例中，内循环风道14形成于蜗壳40内，蜗壳40的出风端与出风口12相对，风道壳50位于蜗壳40的下方、并连接于蜗壳40的远离出风口12的出风端边沿。排风风道15形成于风道壳50的底部并沿前后方向贯通风道壳50。第一风门30可转动安装于壳体10内，第一风门30将过流间隙51与内循环风道14导通时，会阻隔于出风口12与内循环风道14之间，从而内循环风道14内的气流会沿过流间隙51流向排风风道15。第一风门30将出风口12与内循环风道14导通时，第一风门30活动至阻隔于内循环风道14与过流间隙51之间，从而内循环风道14内的气流会直接流向出风口12。
如图4所示，所述出风口12与所述内循环风道14导通时，所述第一风门30搭接于所述风道壳50。在本实施例中，第一风门30将过流间隙51与内循环风道14阻断时，会整体搭接于风道壳50的顶壁，以避免对流向出风口12的气流造成阻碍。此时第一风门30与蜗壳40的出风端边沿可呈平整过渡，以使气流能更稳定流畅地沿第一风门30流动。
如图5至图7所示，所述风机20设置为离心风机20，所述蜗壳40与所述壳体10的内壁之间形成过风通道41，所述第一进风口11与所述蜗壳40的进风端通过所述过风通道41连通。在本实施例中，离心风机20对气流的驱动方式为轴向进风、周向出风，蜗壳40的进风端位于与离心风机20两轴侧相对的两侧壁；气流先从第一进风口11进入过风通道41，再从过风通道41进入蜗壳40。具体地，蜗壳40的数量可为两个，两蜗壳40内均设有风机20，风道壳50与两蜗壳40连接并分别形成两排风风道15，通过两风机20驱动气流进入内循环风道14，既可提高内循环模式的出风效率，又可提高排风模式的排风效率。
如图3、图7和图8所示，所述风道壳50还形成有与所述排风风道15分隔的新风风道52，所述新风风道52连通所述过风通道41与所述排风口13。在本实施例中，排风风道15与新风风道52均与排风口13连通，即排风口13即可用以排出室内污风，也可用以引进室外新风。空气处理模块还具有新风模式，在新风模式，气流的流动路径依次为排风口13-新风风道52-过风通道41-内循环风道14-出风口12，此时第一风门30将内循环风道14与出风口12导通，并将排风风道15阻断，以避免气流紊乱。具体地，风道壳50与排风口13之间可形成过风腔，排风风道15与新风风道52均与过风腔连通，在排风模式，气流会从排风风道15经过风腔流向排风口13；在新风模式，气流会从排风口13经过风腔流向新风风道52。
在实际应用中，所述空气处理模块还包括第三风门80，用以打开或关闭所述第一进风口11；在新风模式，第三风门80关闭第一进风口11，从而风机20的运行只会对新风口造成负压，以使更多的室外新风从新风风道52流入，提高新风的引进效率。相应地，所述空气处理模块还包括第二风门70，用以打开或关闭所述新风风道52；在内循环模式，第二风门70会关闭新风风道52，从而风机20的运行只会对第一进风口11造成负压，以提高内循环模式的出风效率。
如图8所示，所述空气处理模块还包括安装于所述新风风道52的滤网60。在本实施例中，滤网60用以净化流经新风风道52的新风，具体具有除甲醛、杀菌、除尘、消毒、除臭氧等功能中的一种或多种；滤网60可提高进入室内的新风洁净度。结合上述排风模式的实施例，将新风模式和排风模式通过两个分隔的风道实现，从而在排风模式，气流可不用流经滤网60，以提高排风效率。结合上述第二风门70的实施例，滤网60可设于第二风门70远离排风口13的一侧，由此，在非新风模式，滤网60不会暴露于排风口13，以延长滤网60的有效工作寿命。
本申请还提出一种空调室内机，该空调室内机包括室内机本体和一种空气处理模块，该空气处理模块的具体结构参照上述实施例，由于本空调室内机采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。其中，空调室内机可为壁挂式空调室内机或落地式空调室内机。
本申请还提出一种空调器，该空调器包括空调室外机和空调室内机，该空调室内机的具体结构参照上述实施例，由于本空调器采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
