请参阅图1至图8，本申请提供一种新风模块200及包括有新风模块200的空调器的实施例；其中，图5中的虚线箭头表示气流流动方向。新风模块200能够提高优化新风模块200的新风风道，以增大新风模块200输出的新风量。空调器可以为壁挂式空调室内机、或柜式空调室内机、或空气机、或吊顶式空调室内机、或移动式空调器中任意一者。在后文的实施例中，主要以空调器为壁挂式空调室内机为例进行介绍，其他类型可以参照实施。
请参阅图2和图5，在新风模块200的一实施例中，新风模块200包括壳体300、中隔板600及风机组件400。其中，壳体300构造有新风风道330，新风风道330包括进风腔331和出风腔332；中隔板600还贯设将所述进风腔331和出风腔332连通的通风孔610；风机组件400安装于出风腔332内。
具体而言，新风模块200的壳体300可在其底部开设有新风进口301，新风进口301与进风腔331连通；壳体300可在其顶部或前侧部或左侧部或右侧部开设新风出口302，新风出口302和出风腔332连通。具体在此，壳体300可在其底部开设有新风进口301，并朝新风模块200后侧开放，新风进口301通过新风管800与室外环境连通，以自后进风；壳体300可在其前侧部开设新风出口302，以朝新风模块200前侧进风。
请参阅图3至图5，当所述当新风模块200工作时，风机组件400开启，风机组件400驱动新风空气从新风进口301进入新风风道330的进风腔331内，然后从中隔板600的通风孔610通过而进入到出风腔332中，并被出风腔332内的风机组件400沿其径向甩出至新风出口302，最后从新风出口302向外吹出。
由于中隔板600将新风风道330分隔为进风腔331和出风腔332，出风腔332通过中隔板600上的通风孔610连通，也就是相当于将新风风道330进行分段。故相对于整个新风风道330而言，出风腔332的容积小于整个新风风道330的容积。因此，当风机组件400在出风腔332内旋转工作时，风机组件400从中隔板600的通风孔610快速吸入空气并挤压在出风腔332内，从而使得出风腔332风压较高，进而增大风机组件400从新风出口302输出新风量的速率，大大增大新风模块200输出的新风量。
至于净化组件500的结构，可以有多种设计方案，在此没有局限。例如但不局限于：净化组件500包括安装架510及安装于安装架510上的净化件520（如图7所示）。净化件520可适用于去除空气中的粉尘、细颗粒物、微生物、有机挥发性气体（如甲醛等）等空气污染物中任意一种或多种。净化件520的具体类型可依据其功能进行选取，净化件520可以是普通过滤网或HEPA网或除甲醛器或IFD过滤器中任意一种或两种组合；还可以是初效过滤网、中效过滤网、高效过滤网中任意一种或多种组合。
本申请的技术方案，通过在新风模块200的新风风道330内配置中隔板600，以使得新风风道330被分隔为进风腔331和出风腔332，所述进风腔331和出风腔332通过中隔板600上的通风孔610连通，从而相对于整个新风风道330而言，出风腔332的容积小于整个新风风道330的容积。因此，当风机组件400在出风腔332内旋转工作时，风机组件400从中隔板600的通风孔610快速吸入空气并挤压在出风腔332内，从而使得出风腔332风压较高，进而增大风机组件400从新风出口302输出新风量的速率，大大增大新风模块200输出的新风量。
请参阅图5、图7及图8，在一实施例中，壳体300包括底壳310及与底壳310适配盖合的壳盖；其中，底壳310构造有第一腔体311，中隔板600安装于第一腔体311的敞口处，以与第一腔体311配合形成出风腔332。其中，中隔板600与第一腔体311的敞口形状基本适配。装配时，先将中隔板600装配到第一腔体311的敞口处，再将壳盖320盖合到底壳310上，以将中隔板600包围于底壳310和壳盖320之间。
在一实施例中，底壳310还构造有位于第一腔体311一侧的第二腔体312，第一腔体311和壳盖320之间形成所述进风腔331；中隔板600和壳盖320之间间隔形成有过风腔333，所述过风腔333将中隔板600的通风孔610和所述进风腔331连通。
具体说来，所述壳盖320盖设在底壳310上，其中，所述壳盖320的其中一部分罩盖在所述底壳310的第二腔体312上方，并与所述第二腔体312配合形成所述进风腔331。当新风模块200工作时，气流经新风入口进入，而后经所述进风腔331、所述过风腔333、中隔板600的通风孔610进入到出风腔332中，最后从新风出口302吹出。
至于壳体300和中隔板600的具体固定方式，可以先将中隔板600安装于底壳310的第一腔体311的敞口处，该中隔板600和底壳310可以通过卡扣结构卡接和/或通过螺钉结构连接成一个整体；然后，将壳盖320盖合到底壳310和中隔板600连接的整体上，该壳盖320可以与底壳310和/或中隔板600通过卡扣结构、螺钉结构中任意一种或两种连接方式连接固定。
请参阅图5、图7及图8，在一实施例中，风机组件400安装于第一腔体311内，风机组件400包括离心风轮410和第一电机420，离心风轮410的一端与第一电机420连接，离心风轮410的另一端形成进风端，并与中隔板600的通风孔610对应。以在新风模块200工作过程中，进风腔331的气流从中隔板600的通风孔610通过后，直接从离心风轮410的进风端进入到离心风轮410内部，进而由离心风轮410高速甩出，增强离心风轮410送风的效率。
在相关技术中，风机组件400的第一电机420通常是通过单独配置的电机罩，从底壳310的底面安装到底壳310上。因此，第一电机420的安装方向与离心风轮410、或中隔板600或壳盖320的装配方向相反，在装配过程中需要反复调整装配方向，如调整打螺钉的方向。这种装配方式较为繁琐，装配效率较低。
鉴于此，为解决上述技术问题，可选在底壳310的底部朝远离中隔板600的方形凹设有电机安装腔313，所述电机安装腔313朝第一腔体311敞口，以供第一电机420安装。在装配新风模块200时，可以先将第一电机420从底壳310的敞口安装到底壳310的电机安装腔313内；再将离心风轮410安装到底壳310的第一腔体311中，并与第一电机420连接。也就是说，第一电机420和离心风轮410、中隔板600、壳盖320的装配方向一致，无需反复调整装配方向，例如可从正向打螺钉固定，可以实现快速装配。
请参阅图5至图7，在一实施例中，对于中隔板600而言，中隔板600在其中心区域构造形成通风孔610，以与离心风轮410的进风端对应。通风孔610的通风面积与离心风轮410的进风端的进风面积基本一致或略小，这样可以使得从通风孔610通过的大部分气流，能够进入到到离心风轮410，避免向轴向扩散而造成风量损失。在此，中隔板600的通风孔610的通风面积，与中隔板600的侧面面积的比值不小于1/4，且不大于3/4，以确保通风孔610的大小基本与离心风轮410的进风端的进风面积基本一致或略小。
在此考虑到，气流从进风腔331到进入中隔板600的通风孔610时，气流流通的面积有所缩减，通风孔610对气流的阻力较大，气流不易从通风孔610通过。故为解决该问题，可选在中隔板600于通风孔610的周缘构造有导风环611，导风环611自通风孔610的周缘朝向离心风轮410的进风端呈渐缩状延伸设置。
具体说来，导风环611自通风孔610的周缘朝向离心风轮410的进风端凸设，导风环611的直径逐渐缩小，而使得导风环611呈渐缩状设置，导风环611的扩口端对应位于通风孔610处，导风环611的缩口端朝向离心风轮410的进风端。导风环611可以减小气流从该通风孔610通过的阻力，有助于于引导气流从通风孔610通过后精准流入到离心风轮410的进风端，避免气流在通风孔610的出风侧发生扩散而未能进入到离心风轮410的情况出现。
在一实施例中，在离心风轮410的进风端构造有引风圈411，导风环611的缩口端伸入至所述引风圈411内，导风环611的外周壁和所述引风圈411的内周壁之间形成有避空间隙，以供离心风轮410旋转。
具体说来，将导风环611的缩口端伸入至离心风轮410的引风圈411内，可以使得导风环611引导出的气流，在与导风环611分离后直接到达离心风轮410的内部，增大离心风轮410的进风量，进而增大离心风轮410的风量及送风效率。由于导风环611的缩口端伸入至离心风轮410的引风圈411内，为避免两者干涉，故在导风环611的外周壁和所述引风圈411的内周壁之间设置避空间隙，这样可使得离心风轮410的引风圈411可在导风环611外周相对旋转，从而确保旋转过程中两者不发生干涉。
请参阅图3和图4，基于上述任意一实施例，新风模块200还包括温度检测器，所述温度检测器适用于检测新风进风空气的温度。在一实施例中，中隔板600的迎风面构造有传感器固定件620，传感器固定件620位于中隔板600靠近所述前进风腔331的位置，传感器固定件620适用于固定所述温度传感器。当采用传感器固定件620固定所述温度检测器时，可使得该温度传感器较为靠近新风进口301，有利于准确检测新风进风空气的温度。
至于传感器固定件620的结构类型，传感器固定件620可以是通过夹持温度传感器以实现固定的固线夹，也可以是限制温度传感器活动的限位卡槽，亦或者是供温度传感器穿设的固定套筒。具体可根据设计的成本及难以程度进行相应选取，在此不设限定。
请参阅图5至图7，基于上述任意一实施例，新风模块200还包括净化组件500，所述净化组件500沿壳体300的内外向可抽拉地安装于中隔板600上，并位于中隔板600的通风孔610的进风侧。
具体说来，壳体300在新风出口302的一侧开设有安装口，安装口呈长条形设置，并与新风出口302的一侧边同向延伸。净化组件500自安装口可抽拉地安装于中隔板600上。用户可将净化组件500从该安装口向外抽出（如图4中F所指示的方向），以进行清洁或更换；也可以将净化组件500从该安装口推入到中隔板600的通风孔610进风侧，以对从进风腔331经通风孔610流入到出风腔332的气流进行净化，去除空气中的污染物。
此外，由于风机组件400的进风端与该通风孔610对应，故也就相当于，所述净化组件500与风机组件400的进风端对应。进风腔331内的气流先被净化组件500净化成较为洁净的新风空气，而后该洁净的新风空气自通风孔610进入到风机组件400的进风端，最后被风机组件400沿其径向吹出。相对于进风腔331而言，在中隔板600和壳盖320之间的过风腔333空间较大，从而可根据通风孔610的大小相应将净化组件500的供空气通过以实现净化的净化面设计得较大，进而提高增大净化组件500净化空气的效率。由于净化组件500相应设计得较大，从而净化组件500可净化的空气量相应增大，进而还可延长净化组件500的寿命，延长更换净化组件500的周期。
请参阅图7，基于上述任意一实施例，新风模块200还包括安装于新风进口301的阀门组件700，所阀门组件700包括相对新风进口301可转动的新风门710，以及与新风门710连接的第二电机720，所述第二电机720驱动新风门710翻转，而实现新风门710打开或关闭新风进口301。例如，在冬季时期，室外环境温度较低，此时可以将新年门关闭新风进口301，以避免室外冷空气进入冻坏新风模块200，或者经新风模块200进入室内环境。
请参阅图1和图2，本申请还提供一种空调器100，该空调器100包括机壳110及安装于机壳110内的新风模块200。新风模块200的具体结构参照上述实施例，由于本空调器100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。所述空调器100为壁挂式空调室内机、或柜式空调室内机、或空气机、或吊顶式空调室内机、或移动式空调器中任意一者。后文以所述空调器100为壁挂式空调室内机为例进行介绍说明。
在一实施例中，机壳110设有进风口101、第一出风口102及第二出风口103；其中，进风口101和第一出风口102连通。新风模块200安装于所述机壳110内，新风模块200的进风腔331适用于通过新风管800与室外环境连通，新风模块200的出风腔332适用于与第二出风口103连通。由此，所述空调器100具有室内风循环模式和新风模式，其中：
在所述室内风循环模式下，室内环境的空气经进风口101进入到机壳110内部，经机壳110内部的换热组件换热后形成冷风或热风，而后从第一出风口102吹回到室内环境，实现室内风循环；
在所述新风模式下，室外环境的空气经新风管800进入到新风模块200中，经新风模块200的净化组件500净化后形成洁净的新风空气，而后从新风模块200的新风出口302吹到机壳110的第二出风口103，最后从第二出风口103吹到室内环境，实现为室内环境补充新风。
在一实施例中，所述机壳110包括底盘111、面框112及面板113；新风模块200安装于底盘111的端部，新风模块200的新风出口302向面板113开放；面板113的端部开设有第二出风口103，以使得空调器100向前送出新风空气，使得新风空气准确到达用户所在方位。
此外，为避免新风直吹用户，可选将第二出风口103由贯设于面板113上的多个微孔组成，以在新风空气从多个微孔吹出后，气流被打散成一缕缕较小的细丝气流，风速降低，气流变得柔和，不会直接吹向用户，避免用户产生不适感。
为方便安装所述新风模块200，在所述新风模块200的壳体300的底部和/或背部构造有插置部340（插置部340可参阅图4），并在壳体300的前部和/或顶部构造有固定部350（固定部350可参阅图2）；所述空调器的底盘构造有供所述插插置部340对应插置的插槽，以及供所述固定部350连接固定的连接部。安装时，将新风模块200置于底盘内，然后将新风模块200的插置部340与底盘的插槽插置连接，以将新风模块200定位于所述底盘上；而后将新风模块200的固定部350和底盘的连接部采用连接件（如螺钉）穿设连接，从而把新风模块200固定到底盘上，完成新风模块200的安装。
以上所述仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
