具体实施方式
下面将结合附图，对本公开一些实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开所提供的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
除非上下文另有要求，否则，在整个说明书和权利要求书中，术语“包括(comprise)”及其其他形式例如第三人称单数形式“包括(comprises)”和现在分词形式“包括(comprising)”被解释为开放、包含的意思，即为“包含，但不限于”。在说明书的描述中，术语“一个实施例(one embodiment)”、“一些实施例(some embodiments)”、“示例性实施例(exemplary embodiments)”、“示例(example)”、“特定示例(specific example)”或“一些示例(some examples)”等旨在表明与该实施例或示例相关的特定特征、结构、材料或特性包括在本公开的至少一个实施例或示例中。上述术语的示意性表示不一定是指同一实施例或示例。此外，所述的特定特征、结构、材料或特点可以以任何适当方式包括在任何一个或多个实施例或示例中。
本文中“适用于”或“被配置为”的使用意味着开放和包容性的语言，其不排除适用于或被配置为执行额外任务或步骤的设备。

“A和/或B”，包括以下三种组合：仅A，仅B，及A和B的组合。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本公开实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
如本文所使用的那样，“约”、“大致”或“近似”包括所阐述的值以及处于特定值的可接受偏差范围内的平均值，其中所述可接受偏差范围如由本领域普通技术人员考虑到正在讨论的测量以及与特定量的测量相关的误差(即，测量系统的局限性)所确定。

空调器包括一体式空调器和分体式空调器。在分体式空调器中，根据室内机的安装方式不同，可以将室内机分为立式室内机、壁挂式室内机和吊顶式室内机。吊顶式室内机具有占用面积少，安装方式灵活，维修保养方便等优点，适合于安装在宾馆、商场、机场、医院、工厂、科研单位等场所。
图1为根据一些实施例的空调室内机的结构图，图2为根据一些实施例的空调室内机的爆炸图。如图1和图2所示，在一些实施例中，空调室内机为吊顶式室内机，包括壳体100、面板200、风扇组件300、第一导风组件400、以及第二导风组件500。
壳体100大致为四方体结构，包括四个侧壁以及由该四个侧壁围绕形成的内腔，被配置为给风扇组件300(以及室内换热器)提供安装空间。壳体100的底部一侧敞口，敞口处设置有面板200。面板200包括第一环形出风口210。第一环形出风口210的外轮廓形状可以为圆形、矩形、以及其他多边形等多种形状，根据实际设计情况而定。
壳体100包括回风口110，回风口110位于壳体100的侧壁上。当风机组件300被设置于壳体100内时，风机组件300将室内空气经回风口110引入空调室内机，被引入的空气与室内换热器换热后经第一环形出风口210送出。为保证进入空调室内机的空气的洁净度，壳体100还包括过滤网，过滤网设置在回风口110处。
如图3所示，当回风口110位于壳体100的侧壁上、第一环形出风口210位于面板200上时，可知回风口110和第一环形出风口210位于不同的平面上，在空调室内机内部形成的空气流路大致呈“C”形分布，回风流路和出风流路互不影响。在吊顶式空调室内机运行过程中，空气从大致从高处流向低处，能够降低空气的流动阻力，也能够减小阻力带来的风扇组件300运转产生的噪音。
在一些做法中，如图4所示，也可以使面板200既包括第一环形出风口210、又包括回风口240，此时第一环形出风口210和回风口240位于同一平面上，在空调室内机内部形成的空气流路大致呈“U”形分布，回风流路和出风流路容易产生干扰，且增大了回风的阻力。
为使回风口和第一环形出风口之间的空气流路更加清楚，图3和图4省略了一些部件，例如第一导风组件400和第二导风组件500等未在图3和图4中示出。
风扇组件300包括风扇310、电机320以及风扇护罩330。
电机320与壳体400固定连接，被配置为驱动风扇310运转。
风扇310被配置为将室内空气经回风口110吸入至空调室内机内部，并将与室内换热器换热后的室内空气经由第一环形出风口210送出。风扇310为室内空气的流动提供动力。风扇310为斜流风机，能够使第一环形出风口210处的空气既做离心运动又做周向运动，从而使空气流向室内的多个角落，保证空调室内机的出风均匀。
风扇护罩330设置在壳体100所形成的内腔内，并位于风扇310的径向外侧，被配置为将风扇310产生的气流引导至第一环形出风口210。风扇护罩330的靠近第一环形出风口210的端部(例如，底部)与第一环形出风口210的边缘A正对。
第一导风组件400安装在面板200上，被配置为对从第一环形出风口210吹出的风的方向进行控制。在第一环形出风口210的边缘A和第一导风组件400的边缘B之间形成第二环形出风口440，第二环形出风口440为第一环形出风口210的一部分，气流经过第二环形出风口440流出。
第一导风组件400能够向靠近面板200的方向或向远离面板200的方向运动，从而借助于第一导风组件400，本公开一些实施例提供的空调室内机可以实现三种送风模式。第一种为冷风沉降式送风模式，即第二环形出风口440吹出的风的方向近似水平，水平的气流从房间顶部向下沉降，达到冷风沉降的效果。第二种为瀑布式送风模式，即从第二环形出风口440吹出的风的方向近似垂直向下。第三种为森林风式送风模式，即从第二环形出风口440吹出的风的状态在冷风沉降模式和瀑布式送风模式之间切换变化。
示例性地，如图5A、6A和7A所示，第一导风组件400向靠近面板200的方向(例如，向上)运动至极限位置时，第一导风组件400的边缘B最靠近第一环形出风口210的边缘A，在此情况下第二环形出风口440最小，气流近似以水平方向从第二环形出风口440流出，从而实现近似水平送风。由于空调室内机位于房间的顶部，因此水平吹出的气流可以缓慢沉降，实现冷风沉降式送风模式。
冷风沉降式送风模式能够避免冷风直吹用户，实现无风感送风，为用户提供较为均匀、舒适的降温体验。
如图5B、6B和7B所示，第一导风组件400向远离面板200的方向(例如，向下)运动至极限位置时，第一导风组件400的边缘B最远离第一环形出风口210的边缘A，在此情况下第二环形出风口440最大，气流近似以竖直方向从第二环形出风口440流出，从而实现近似竖直向下送风。
瀑布式送风模式可以增强用户的吹风体感，吹风更为直接，制冷降温或制热升温均较快。
当第一导风组件400在靠近面板200的极限位置和远离面板200的极限位置之间反复上下运动时，第二环形出风口440的大小反复变化，从第二环形出风口440吹出的风的状态在冷风沉降式送风和瀑布式送风之间反复变化，这样的送风模式被称为森林风式送风模式。
在森林风式送风模式下，用户仿佛置身于森林中，感受到的是一阵一阵的气流吹向身体，享受到更为接近自然风的吹风体验。
为了将第一导风组件400安装于面板200，且使第一导风组件400能够向靠近或远离面板200的方向运动，空调室内机还包括第一驱动组件900。
如图8A、9A和10A所示，在一些实施例中，面板200包括安装部220，第一环形出风口210环绕安装部220的外周设置。安装部220被配置与第一驱动组件900连接。第一驱动组件900进一步被配置为与第一导风组件400连接，从而使得第一导风组件400与面板200连接并相对于面板200运动。
如图8A至8F(图8A至8F示出的第一导风组件与图5A至5B示出的第一导风组 件相同)、图9A至9L(图9A至9L示出的第一导风组件与图6A至6B示出的第一导风组件相同)、以及图10A至10C(图10A至10C示出的第一导风组件与图7A至7C示出的第一导风组件相同)所示，第一导风组件400包括底板410、导风圈420和装饰罩430。
底板410位于导风圈420远离面板200的一侧，即底板410位于导风圈420的下方。底板410被配置为与第一驱动组件900固定连接，第一驱动组件900带动底板410运动，即可实现第一驱动组件900带动整个第一导风组件400运动。底板410通过螺钉、卡扣等方式与导风圈420固定连接。
导风圈420为圆锥状结构，导风圈420自其顶部至边缘沿曲线向下延伸。第一导风组件400的边缘B即为导风圈420的边缘。导风圈420具有开孔421，第一驱动组件900的一端与底板410固定连接后，其另一端穿过开孔421并与面板200的安装部220固定连接。
装饰罩430与导风圈420通过卡扣固定连接，或者与第一导风组件400中的其他部件通过卡扣固定连接。装饰罩430被配置为对底板410进行遮挡，以保证空调室内机的美观。在一些实施例中，装饰罩430是可选的且是可省略的。
图11A至11B、以及图12A至12D示出了两种不同的第一驱动组件900。
如图11A至11B所示，第一驱动组件900包括升降驱动组件910和固定组件920。升降驱动组件910包括外壳911、驱动电机912、齿轮913、以及齿条部914。
外壳911为两半式结构，包括第一外壳9111和第二外壳9112，第一外壳9111和第二外壳9112通过螺钉、卡扣等方式固定连接。驱动电机912、齿轮913以及齿条部914位于外壳911的内腔中，外壳911的两半式结构便于这些部件的安装。外壳911包括凸耳9113(参见图8A和9A)，凸耳9113位于外壳911的外壁上；凸耳9113通过螺钉与面板200的安装部220固定连接，实现第一驱动组件900与面板200之间的固定连接。
齿条部914也为两半式结构，其包括第一齿条部9141和第二齿条部9142，第一齿条部9141和第二齿条部9142通过螺钉、卡扣等方式固定连接。齿条部914还包括齿条段9143；齿条段9143位于第一齿条部9141上，并与齿轮913啮合。
外壳911还包括开口9114，开口9114位于外壳911的底部。齿条部914的底端从开口9114伸出，并与固定组件920连接。
固定组件920包括连接盘921，连接盘921与齿条部914固定连接或一体成型。连接盘921通过螺钉与第一导风组件400的底板410固定连接，实现第一驱动组件900与第一导风组件400之间的固定连接。
驱动电机912被配置为驱动齿轮913转动，齿轮913转动带动齿条段9143上下运动。由于外壳911与面板200的安装部220固定连接、齿条部914与第一导风组件400的底板410固定连接，因此当齿条段9143带动齿条部914整体上下运动时，齿条部914能够带动第一导风组件400整体相对于壳体911上下运动。
在一些实施例中，升降驱动组件910还包括滚轮915。滚轮915的安装轴位于齿条 部914中，齿条部914的两半式结构便于滚轮915的安装。滚轮915的一部分位于齿条部914的内腔中、另一部分位于齿条部914的内腔外。滚轮915从齿条部914露出的部分与外壳911的内壁滚动接触。滚轮915有助于提高齿条部914上下运动的可靠性以及平稳性，同时有助于减小运动摩擦。
第一驱动组件900带动第一导风组件400整体上下运动时，可使第一导风组件400处于图5A和图6A所示的位置、或处于图5B和图6B所处的位置、或前述两个位置之间的任何位置。
当采用图11A至11B所示的第一驱动组件900时，第一导风组件400能够进行升降运动而不能进行转动。在此情况下，可以使第一导风组件400仅通过一个第一驱动组件900连接至面板200。当然，本公开并不局限于此，也可以使用多个第一驱动组件900。
当仅使用一个第一驱动组件900时，如图8A至8F、以及图9A至图9L所示，底板410包括轴411，该轴411例如为圆柱轴。轴411自底板410的中心向远离底板410的方向延伸。轴411具有空腔412，该空腔412穿透轴411的顶端。第一驱动组件900伸入空腔412中；其固定组件920，例如连接盘921，与空腔的底部413固定连接，例如通过螺钉固定连接。
导风圈420具有开孔421，轴411的顶部从该开孔421伸出，使得第一驱动组件900也从该开孔伸出。第一驱动组件900伸出导风圈420的部分通过凸耳9113与面板200的安装部220固定连接。
在一些实施例中，如图8A至8F、以及图9A至图9L所示，轴411包括多个滑道414和嵌入于每个滑道414内的多个滚珠415。例如，轴411包括沿轴411的周向对称布置的三个滑道414，每个滑道414内嵌入有间隔布置的两个滚珠415。
结合图5A至图6B所示，安装部220包括安装腔221。安装腔221例如为圆柱腔。轴411伸入安装腔221内，滚珠415与安装腔221的内壁滚动接触。当第一导风组件400在第一驱动组件900的作用下进行升降运动时，一方面，齿条部914通过滚轮915沿外壳911的外壁滑动，另一方面，齿条部914带动底板410的轴411通过滚珠415沿面板200的安装腔221的内壁滑动。通过滚珠415，可以提高第一导风组件400整体运动的可靠性以及平稳性，也有助于减小运动摩擦。
在一些实施例中，如图5A至图6B所示，安装部220具有限位部222。限位部222的形状与导风圈420的形状相适配，例如限位部222也为圆锥状结构。导风圈420向靠近面板200的方向运动时可以与限位部222抵靠，实现对第一导风组件400的限位。
图12A至12D示出了另一种第一驱动组件900。除升降驱动组件910和固定组件920外，该第一驱动组件900还包括转动驱动组件930。转动驱动组件930位于升降驱动组件910和固定组件920之间。升降驱动组件910和固定组件920的结构和功能与上述相同，故不再赘述。
转动驱动组件930包括基座931、滚动球932、销钉933以及限位块934。基座931包括容纳腔9311，容纳腔9311的顶部呈收口状，滚动球932内嵌于容纳腔9311中并能 够在容纳腔9311中转动。限位块934位于容纳腔9311中，并位于滚动球932的下方，以对滚动球932进行限位。
销钉933的一端与滚动球932固定连接、另一端伸入齿条部914内。齿条部914还包括能够对销钉933进行固定限位的限位槽9144。销钉933将升降驱动组件910和转动驱动组件930连接起来，并且销钉933既不影响升降驱动组件910的动作，也不影响转动驱动组件930的动作。
固定组件920的连接盘921与基座931固定连接或一体成型。
第一驱动组件900带动第一导风组件400整体上下运动时，可使第一导风组件400处于图7A或7B所示的位置、第一驱动组件900带动第一导风组件400转动时，可使第一导风组件400处于图7C所示的位置。
如图10A至10C所示，空调室内机包括多个第一驱动组件900，例如三个。该三个第一驱动组件900沿面板200的中心轴呈周向均匀分布。当三个第一驱动组件900同步动作时，能够驱动第一导风组件400上下运动。当三个第一驱动组件900的动作不同步时，能够驱动第一导风组件400相对于面板200倾斜。
在一些实施例中，如果多个第一驱动组件900按照一定的时间周期进行交替动作，则能够实现第一导风组件400绕面板200的中心轴摆动，使不同方向上的送风量和送风角度达到周期性变化的效果。
第一导风组件400相对于面板200的上下运动和倾斜运动可以同时发生、也可以不同时发生。通过第一导风组件400的上下运动和倾斜运动的配合，空调室内机可以达到不同的送风模式，实现送风量和送风角度的精确控制。
需要说明的是，在一些实施例中，第一驱动组件900是可选的且是可省略的。即，可以将第一导风组件400直接(或者通过其他连接件间接)与面板200相连。或者在一些实施例中，第一驱动组件900仅包括转动驱动组件930和固定组件920，而不包括升降驱动组件910，此时第一驱动组件900可驱动第一导风组件400进行倾斜运动。
在本公开一些实施例中，除了通过第一驱动组件900带动第一导风组件400上下运动和/或倾斜运动来达到控制第二环形出风口440处的风向的目的外，还可以通过第一导风组件400中的导风板来达到控制上述风向的目的。导风板有多种不同的实现形式。
在一种实现形式中，如图8A至8F所示，第一导风组件400包括多个第一导风板450A，多个第一导风板450A位于底板410上，且每个第一导风板450A可以相对于底板410上下摆动。通过第一导风板450A的摆动，可以调节从第二环形出风口440流出的空气的方向，实现送风角度的调节。
导风圈420包括多个窗口422，多个第一导风板450A一一对应地位于多个窗口422中。第一导风板450A的表面曲率与导风圈420的表面曲率大致相同，当第一导风板450A未摆动时，第一导风板450A能够与导风圈420合成一体结构，实现较好的导风效果。
在一些实施例中，导风圈420包括支撑筋423，支撑筋423与底板410抵靠。通过支撑筋423，一方面提高导风圈420的结构强度和安装稳固性，另一方面防止气流经过 窗口422进入到第一导风组件400的内部。
导风圈420包括多个支撑筋423，多个支撑筋423与多个窗口422一一对应。每个支撑筋包括第一支撑筋4231、第二支撑筋4232以及第三支撑筋4233。每个窗口422具有相对设置的第一侧边4221和第三侧边4223、以及相对设置的第二侧边4222和第四侧边4224。第一支撑筋4231自第一侧边4221向下延伸至与底板410抵靠，第二支撑筋4232自第二侧边4222向下延伸至与底板410抵靠，第三支撑筋4233自第三侧边4223向下延伸至与底板410抵靠。
每个第一导风板450A都依靠一个独立驱动机构来实现摆动。多个第一导风板450A的摆动角度可以相同、也可以不相同。当多个第一导风板450A的摆动角度不相同时，空调室内机在不同方向上的送风角度不同，进一步满足用户不同的吹风需求。
由于导风圈420呈圆锥状结构，故在底板410和导风圈420之间形成有一个空间。该空间为第一导风板450A的摆动和第一导风板450A的驱动机构的设置提供了空间。第一导风板450A的驱动机构包括第一导风板驱动电机460A。第一导风板驱动电机460A被配置为驱动第一导风板450A在导风圈420的窗口422内摆动，实现风向调节。
在一些实施例中，第一导风板450A包括连接筋451A和位于连接筋451A上设有轴孔452A。底板410包括安装柱416，第一导风板驱动电机460A固定设于安装柱416上，第一导风板驱动电机460A的电机轴与轴孔452A连接。通过第一导风板驱动电机460A对第一导风板450A的运动进行控制。
导风圈420还包括让位槽424，让位槽424位于第二支撑筋4232上。第一导风板驱动电机460A位于让位槽424内。
在冷风沉降式送风模式、瀑布式送风模式或森林风式送风模式下，第一导风板450A可以运动、也可以不运动。当第一导风板450A运动时，可以进一步调节各个送风模式下的风向。
此外，第一导风板450A的上下摆动可以与第一导风组件400的上下运动和/或倾斜运动同时或不同时进行，以达到各种不同的送风模式。
在另一种实现形式中，如图9A至9L所示，第一导风组件400包括多个第二导风板450B，多个第二导风板450B可以从第一导风组件400伸出或缩回至第一导风组件400。通过第二导风板450B的伸出或缩回，可以调节第二环形出风口440的大小，进而调节从第二环形出风口440流出的空气的方向，实现送风角度的调节。
第二导风板450B伸出，第一导风组件400整体的边缘增大，第二环形出风口440变小；第二导风板450B缩回，第一导风组件400整体的边缘缩小，第二环形出风口440变大。在一些实施例中，多个第二导风板450B伸出时，相邻两个第二导风板450B至少部分上下重叠，避免相邻两个第二导风板450B之间具有缝隙而影响导风效果。
第一导风组件400还包括第二导风板驱动电机460B和驱动板470，第二导风板驱动电机460B为驱动板470的旋转提供动力。当驱动板470旋转时，驱动板470带动多个第二导风板450B伸出或缩回。
驱动板470包括多个弧形驱动滑道471，每个弧形驱动滑道471的轨迹根据第二导风板450B的径向运动与驱动板471的旋转运动拟合而成。底板410包括间隔设置的多个直线导向滑道417，多个直线导向滑道417围绕底板410的中心轴线放射状分布。多个弧形驱动滑道471与多个直线导向滑道417一一对应；一个弧形驱动滑道471和对应的一个直线导向滑道417形成的组合对应一个第二导风板450B。
在一些实施例中，第一导风组件400包括六个第二导风板450B，则驱动板470包括六弧形驱动滑道471，底板410包括六个直线导向滑道417。
第二导风板450B包括第一导向凸起451B和第二导向凸起452B，第一导向凸起451B滑动设于直线导向滑道417内，第二导向凸起452B滑动设于弧形驱动滑道471内。
第二驱动电机460B驱动驱动板470旋转，弧形驱动滑道471向第二导向凸起452B施加作用力，使第二导向板450B具有旋转的运动趋势；但是由于第一导向凸起451B限位于直线导向滑道417内，所以第二导向板450B不能够旋转，而是沿着直线导向滑道417滑动，从而实现第二导向板450B的伸出或缩回。
第二导风板450B的迎风面为具有导风性能的曲面，例如螺旋面、弧面等，以提高导风效果。在一些实施例中，第二导风板450B的迎风面为螺旋面。如图9G所示，将第二导风板450B的迎风面的四个角分别标记为C1、C2、C3以及C4，C1点的高度大于C2点的高度，C2点的高度大于C3点的高度，C3点的高度大于C4点的高度。
第二导风板450B相对的两端分别为高端侧451和低端侧452，也即高端侧451为C1和C2所在的一侧，低端侧452为C3和C4所在的一侧。第二导风板450B包括台阶453B；相邻的两个第二导风板450B中，一个第二导风板450B的低端侧452位于另一个第二导风板450B的台阶453B内，以避免相邻两个第二导向板450B在运动时的干涉，并且使相邻两个第二导风板450B能够具有部分重叠，避免出现间隙而影响导风效果。
在一些实施例中，参照图9K所示，导风圈420还包括避让槽425，避让槽425位于导风圈420的靠近底板410的一侧，避让槽425被配置为为第二导风板450B的运动提供空间。
在一些实施例中，多个第二导向板450B可被一个驱动板470驱动，而驱动该驱动板470的第二导风板驱动电机460B则位于底板410的空腔412内。例如，如图9L所述，空腔412包括被空腔的底部413分隔成的第一子空腔4121和第二子空腔4122，第一驱动组件900的连接盘921位于第一子空腔4121内并固定于空腔的底部423，第二导风板驱动电机460B则位于第二子空腔4122内并与驱动板470固定连接以驱动驱动板470旋转。
还应注意的是，当第一导风组件400包括装饰罩430时，由于驱动板470位于装饰罩430和导风圈420之间，因此当将装饰罩430与导风圈420连接时会妨碍第二导风板450B的伸出或缩回；为此，可以将装饰罩430通过卡扣等方式与驱动板470固定连接。
在冷风沉降式送风模式、瀑布式送风模式或森林风式送风模式下，第二导风板450B可以运动、也可以不运动。当第二导风板450B运动时，可以进一步调节各个送风模式 下的风向。
此外，第二导风板450B的伸出或缩回可以与第一导风组件400的上下运动和/或倾斜运动同时或不同时进行，以达到各种不同的送风模式。
在一些实施例中，如图1至2以及图13A至13C所示，空调室内机还包括第二导风组件500和第二驱动组件600，第二导风组件500位于第一导风组件400靠近壳体100的一侧。第二驱动组件600驱动第二导风组件500转动，第二导风组件500能够使从第二环形出风口440吹出的风更加柔和。
第二导风组件500包括沿径向方向排列的固定内板510和固定外板520，以及排列在固定内板510和固定外板520之间的多个叶片530，多个叶片530之间具有导风间隙，空气从导风间隙输出。固定内板510与固定外板520均为圆环形，固定外板520位于固定内板510的径向外侧；叶片530为圆弧形，从而使相邻导风板530之间的导风间隙也为圆弧形，有利于增大空气输送面积。
第二导风组件500位于面板200靠近壳体100的一侧，且与面板200之间具有一定的间隙。例如，第二导风组件500具有第一感应部，面板200具有第二感应部，第一感应部与第二感应部互斥，使得第二导风组件500与面板200之间形成间隙。第一感应部以及第二感应部例如为磁性感应部，利用同性相斥的原理将第二导风组件500从面板200分离，防止面板200干涉其转动。这样，有利于减少第二导风组件200的磨损，增加其使用寿命。
第二导风组件500由第二驱动组件600驱动，第二驱动组件600包括第二驱动电机610和连接在第二驱动电机610的输出端的主动轮620。第二驱动组件600固定在面板200上，例如第二驱动电机610和主动轮620各自的轴固定在面板200上。第二导风组件500还包括多个齿540，多个齿540均布在固定外板520的外侧壁上，主动轮620与多个齿540啮合。第二驱动电机610启动后，带动主动轮620转动，主动轮620进而驱动第二导风组件500转动。
在第二导风组件500的旋转过程中，第一环形出风口210处的风能够不断地经过旋转的叶片530，叶片530切割第一环形出风口210处的风所形成的气流，是的吹出的风更加柔和，并且实现均匀出风。
在第二导风组件500转动的过程中，受到主动轮620的作用，第二导风组件500可能会发生偏斜，从而使其中心轴线偏离面板200的中心轴线。为了提高第二导风组件500稳定性，在第二导风组件500的周围还设置多个从动轮630，多个从动轮630沿周向分布在第二导风组件500外侧，且均与第二导风组件500的多个齿540啮合。
在主动轮620沿径向从一个方向作用在第二导风组件500上的时候，从动轮630沿径向从另一个方向作用在第二导风组件500上，使得第二导风组件500不至于移位，保证了第二导风组件500工作的稳定性。
在一些实施例中，第二驱动组件600包括两个主动轮620和三个从动轮630，该两个主动轮620和三个从动轮630在第二驱动组件600的外周均匀分布。
此外，为了提高空调室内机整体的安全性，防止第二导风组件500因为上述的感应作用失效而掉落，从而产生安全隐患，面板200还包括固定在其朝向第二导风组件500的表面上的多个防护板230。每个防护板230为圆弧形，并位于相邻主动轮620和/或从动轮630之间。当第二导风组件500掉落时能够落在多个防护板230上，从而避免第二导风组件500掉落在第一导风组件400上或者直接掉落在地面上。
在一些实施例中，如图14A-14C所示，空调室内机还包括接水盘700和位于接水盘700与风扇组件300之间的保温组件800。
当空调器在制冷模式下运行时，空调室外机中的换热器作为冷凝器、空调室内机中的换热器作为蒸发器。冷凝器将其内部的冷媒的热量散发至室外空气中，蒸发器内的冷媒则吸收室内空气的热量以使室内温度降低，故冷凝器的温度高、蒸发器的温度低。当蒸发器的温度低于室内温度时，室内空气中的水蒸气就在蒸发器的表面冷凝成液态的水。尤其是夏季空气湿度大含有的水分多的时候，蒸发器的表面更容易形成冷凝水。类似地，当空调器在除湿模式(尤其是降温除湿模式)下运行时也会在空调室内机中产生冷凝水。接水盘700能够收集空调室内机运行时产生的冷凝水，并将冷凝水从空调室内机排出。
风扇组件300包括风扇护罩330，接水盘700位于风扇护罩330的径向外侧，保温组件800位于风扇护罩330与接水盘700之间。风扇护罩330具有弧形导风面331，保温层800具有与导风面331形状相适应的内壁801。
风扇护罩330包括多个第一锁紧部332；多个第一锁紧部332沿周向均布在风扇护罩330的外周。与第一锁紧部332对应，接水盘700包括多个第二锁紧部701，每个第二锁紧部701与对应的第一锁紧部331配合连接。
在一些实施例中，风扇护罩330还具有翻边333，多个第一锁紧部332沿着周向均布在翻边333上。翻边333除了承载第一锁紧部332外，还可以与保温层800压紧并连接。
在第一锁紧部332与第二锁紧部701连接时，保温层800被夹紧在风扇护罩330与接水盘700之间，有利于使得风扇护罩330和保温层800的固定更加稳定和牢固。例如，保温层800具有安装通孔801，第一锁紧部332与第二锁紧部701在安装通孔801内配合连接。
第一锁紧部332与第二锁紧部701可以通过螺钉固定连接，还可以通过卡扣的形式连接。螺钉固定连接的方式即螺钉穿过第一锁紧部332并紧固在第二锁紧部701上。
第一锁紧部332与第二锁紧部701通过卡扣的形式连接时，第一锁紧部332包括第一锁紧板3321和位于第一锁紧板3321上的连接口3322；第一锁紧板3321从翻边333朝向远离翻边333的方向延伸，即朝向接水盘700延伸。第二锁紧部701包括第二锁紧板7011和位于第二锁紧板7011上的锁紧块7012；第二锁紧板7011从接水盘700表面朝向远离接水盘700的方向延伸，即朝向风扇护罩330的方向延伸；锁紧块7012沿径向凸出于第二锁紧板7011的外侧面，锁紧块7012连接到第一锁紧部332的连接口3322内，进而将第一锁紧部332和第二锁紧部701连接。
在锁紧过程中，为了使第一锁紧部332更加顺畅地与第二锁紧部701连接，第二锁紧部701还包括斜面7013，斜面7013位于锁紧块7012上，并沿着远离第一锁紧部332的方向逐渐向接水盘700的径向外侧延伸。当第一锁紧部332向第二锁紧部701移动的时候，在斜面7013的作用下，锁紧块7012向接水盘700的径向内侧被挤压，方便第一锁紧部332移动到第二锁紧部701的径向外侧。
当第一锁紧部332的连接口3322与第二锁紧部701锁紧块7012相对的时候，锁紧块7012被释放复位，并进入到连接口3322内，实现第一锁紧部332和第二锁紧部701的连接。
为了加强第一锁紧板3321的结构强度，第一锁紧部332还包括第一加强筋3323，第一加强筋3323位于第一锁紧板3321的两个侧边处。并且，第一加强筋3323端部连接在翻边333上，这有利于在第一锁紧部332和第二锁紧部701连接固定过程中，增强第一锁紧部332的稳定性。
类似地，为了加强第二锁紧板7011的结构强度，第二锁紧部701还包括第二加强筋7014，第二加强筋7014位于第二锁紧板7011的两个侧边处。这有利于在第一锁紧部332和第二锁紧部701连接固定过程中，增强第二锁紧部701的稳定性。
在一些实施例中，为了更好地定位风扇护罩330，且更加牢固地将保温组件800夹持在风扇护罩330和接水盘700之间，保温组件800还包括环形的安装凹槽802，多个安装通孔801均布在安装凹槽802内。风扇护罩330的翻边333位于安装凹槽802内，由于安装凹槽802的内径与翻边333的外径一致，因此有利于风扇护罩330在安装过程中的定位，并提高安装速度。
上述风扇护罩330、接水盘700和保温组件800的安装结构简单，易于加工制造，提高了加工速度以及装配效率。并且风扇护罩330、接水盘700和保温组件800之间的连接稳定，连接强度高。
在上述实施方式的描述中，具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。例如，虽然上述图11A和图11B示出的第一导风组件400不包括导风板，但如图15所示，也可以在上述图11A和图11B示出的第一导风组件400中设置导风板。
最后应说明的是，以上实施例仅用以说明本公开的技术方案，而非对其限制；尽管参照前述实施例对本公开进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
