进一步地，本发明的设计人意识到，由于离子风发生装置内部设置有高压放电装置，因此在离子风发生装置的工作过程中，会产生一定量的有害气体(主要为O 3和氮氧化物)。为防止这些气体排向室内，本发明在每个离子风发生装置的下游均设置一净化装置，每个离子风发生装置产生的有害气体均能够被吸收，因此能够更加全面地去除供往室内的空气中的氮氧化物和臭氧等有害物质，从而进一步提高了净化效果。
根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。

具体实施方式
本发明实施例提供一种壁挂式空调室内机，图1是根据本发明一个实施例的壁挂式空调室内机的示意性结构图，图2是根据本发明一个实施例的壁挂式空调室内机的示意性结构分解图。本发明的壁挂式空调室内机1包括机壳10和设置于机壳10内的至少一个净化装置50。机壳10具有用于供气流流入其中的进风口11和用于供气流流出的至少一个出风口。具体地，机壳10包括前壳18和后盖19，进风口11形成在后盖19上。壁挂式空调室内机1向其前方送风，因此，进风口11可设置在机壳10的上侧或后侧，出风口可设置于机壳10的前侧或下侧。出风口的数量可以为一个、两个或多于两个的更多个。每个净化装置50均位于进风口11至相应的一个出风口的气流流动路径上，以去除流经其的空气中的杂质，并对空气进行净化。具体地，净化装置50可通过吸附、分解或其他方式去除流经其的空气中的氮氧化物、臭氧和其他不利于人体健康的有害气体，从而使得流向室内的空气为洁净的 空气。净化装置50的数量也可以为一个、两个或多于两个的更多个。净化装置50的数量可与出风口的数量相同，每个出风口均对应一个净化装置50，从而使得经每个出风口送出的空气均能够得到净化。在一些替代性实施例中，净化装置50的数量与出风口的数量也可以不同。
图3是根据本发明一个实施例的净化模块的示意性正视图，图4是沿图3中的剖切线A-A截取的示意性剖视图。参见图3和图4，每个净化装置50均包括芯体51，芯体51具有多个用于供气流流过的通孔511，每个通孔511均沿该净化装置所在的气流流动路径的气流流动方向倾斜向下地贯穿芯体51。例如，当该净化装置所在的气流流动路径的气流流动方向为由后向前时，其通孔511由后向前地倾斜向下贯穿芯体51，即其通孔511由后向前地倾斜向下延伸。一方面，能够调节室内机的送风方向，使气流向前侧下方倾斜一定的角度送出，实现了较好的制冷体验和制热体验；另一方面，延长了通孔511的长度，增加了空气与通孔511内壁的接触时间和接触面积，从而提高了净化装置50的净化效果。
进一步地，多个通孔511均匀分布在芯体51上，每个通孔511的内径均相同，且同一芯体51的多个通孔511的倾斜角度一致，以有利于均匀送风。
在本发明的一些实施例中，净化装置50还包括用于容装芯体51的框架52，框架52的内侧表面和每个通孔511的内壁均涂覆有用于加速氮氧化物和臭氧分解的催化物质，以提高氮氧化物和臭氧的分解速度，从而提高净化效果。
进一步地，该催化物质可包括第一催化剂和第二催化剂两种。第一催化剂包括用于加速氮氧化物分解的金属氧化物，例如可以包括：TiO 2、WO 3或V 2O 5等等。第二催化剂包括用于加速臭氧分解的锰铈或锰铁或锰钴复合金属氧化物。
在一些优选实施例中，第一催化剂和第二催化剂分别涂覆于通孔511的沿其内部气流流动方向的上游区段和下游区段的内壁表面，或者分别涂覆于通孔511的沿其内部气流流动方向的下游区段和上游区段的内壁表面。也就是说，通孔511的内壁表面可分成两个区段，分别为在其内气流流动方向上处于上游的上游区段和处于下游的下游区段，其中一个区段上涂覆第一催化剂，另一个区段上涂覆第二催化剂。换句话说，第一催化剂和第二催化剂分 别涂覆在通孔511内壁的不同位置处，一方面，能够避免两种催化剂混合产生不必要的化学反应，另一方面，能够同时分解氮氧化物和臭氧，从而对其进行有效去除。
进一步地，净化装置50所处的气流流动路径上的气流流动方向为其厚度方向。净化装置50的厚度优选为10mm-60mm，使得净化装置50既能具有较好的净化效果，又相对较薄，节省壁挂式空调室内机1内部的容纳空间。在本实施例中，净化装置50的厚度优选为40mm，并且，其靠近出风口一侧的厚度为20mm的部分，其通孔内壁涂覆第二催化剂；其远离出风口一侧的厚度为20mm的部分，其通孔内壁涂覆第一催化剂。也即是，净化装置50首先对氮氧化物进行分解去除，再对臭氧进行分解去除，这种顺序有利于彻底地去除两种有害气体，从而彻底地净化空气。
在本发明的一些实施例中，每个通孔511与竖直平面所成的处于下方的夹角α为范围在10°～80°之间的任一角度值。由此，既能够达到良好的制冷制热体验，又能够避免净化装置50对气流产生过大的阻力而导致噪音过大、风量较小的问题。具体地，每个通孔511与竖直平面所成的处于下方的夹角α可以为10°、20°、30°、40°、50°、60°、70°或80°。进一步地，当每个通孔511与竖直平面所成的处于下方的夹角α为50°～80°之间的任一值时，能够同时取得较佳的净化效果和送风效果。在本发明的一个优选实施例中，α的取值为75°。
在本发明的一些实施例中，壁挂式空调室内机1还包括用于利用电场力促使由进风口11进入的至少部分空气朝向至少一个出风口中的一个或多个流动的至少一个离子风发生装置30。离子风发生装置30能够利用电场力产生离子风，离子风的产生源于电晕放电原理。由于高压电的作用，离子风发生装置30的针状电极附近电场强度极大，使区域内的大量空气分子产生电离。在电场的作用下，带电粒子作定向移动，且在运动过程中与不带电的中性粒子碰撞，把部分动能传递给中性粒子，使其一起做定向移动，即产生离子风。
本发明通过至少一个离子风发生装置30驱动送风，其能够代替至少部分旋转类送风部件(例如风机)。由于离子风发生装置30是依靠电场力使空气中的粒子获得动能，从而形成离子风，因此，相比于旋转类的送风组件来说，离子风发生装置30具有压损小、耗能低、噪音小等优势，从而在很 大程度上减小了壁挂式空调室内机1运行时的噪音。同时，由于离子风发生装置30产生的离子风不是依靠压力产生的，而是通过电场力产生的一种贴近于自然的柔和风，因此能够提高壁挂式空调室内机1的舒适度。
在设置离子风发生装置30的同时，本发明的设计人还意识到，由于离子风发生装置30内部设置有高压放电装置，因此在离子风发生装置30的工作过程中，会产生一定量的有害气体(主要为O 3和氮氧化物)。为了防止这些有害气体排向，本发明将离子风发生装置30和净化装置50特别设计如下：离子风发生装置30与净化装置50的数量相同，每个离子风发生装置30在机壳10内的气流流动方向上均位于相应的一个净化装置50的上游，并与该净化装置固定连接成能够同时拆装的一个整体。不但简化了壁挂式空调室内机1的组装过程、省去了净化装置50的固位结构、减小了占用空间和壁挂式空调室内机1的体积，而且还使得每个离子风发生装置30产生的有害气体均能够被吸收，因此能够更加全面地去除供往室内的空气中的氮氧化物和臭氧等有害物质，从而进一步提高了净化效果。
在本发明的一些实施例中，参见图1和图2，上述至少一个出风口12设置于机壳10的前侧，进风口11设置于机壳10的后侧或上侧。离子风发生装置30和净化装置50的数量均为一个，净化装置50设置于离子风发生装置30的正前方。机壳10内的气流流动方向为由后向前，此时净化装置50的通孔511由后向前地倾斜向下延伸，即通孔511的前端开口低于其后端开口。
进一步地，壁挂式空调室内机1还包括用于与流经其的空气进行热交换的换热装置40。换热装置40可设置于离子风发生装置30的后侧或设置于净化装置50的前侧。具体地，换热装置40可以为板状蒸发器。
图5是根据本发明另一个实施例的壁挂式空调室内机的示意性结构分解图。在图5所示实施例中，出风口的数量为多个，包括分别设置于机壳10的横向两侧且朝向机壳10侧向前方的两个侧向出风口13。由此，壁挂式空调室内机1可分别朝向机壳10的横向外侧的前方送风，形成了环抱式的送风效果，不但扩大了壁挂式空调室内机1的送风范围，而且避免了冷风或热风直接吹向人体，提高了室内温度的均匀性。
进一步地，离子风发生装置30和净化装置50的数量均为两个，两个离子风发生装置30分别设置在进风口11至两个侧向出风口13的气流流动路 径上，两个净化装置50分别设置在两个离子风发生装置30的外侧。此时，两个净化装置50所在的气流流动路径的气流流动方向为由内向外、由中间向两边。因此，净化装置50的通孔511由内向外地倾斜向下延伸，即通孔511的靠近机壳10中心的内侧端口的高度高于其远离机壳10中心的外侧端口的高度。
在图5所示的实施例中，出风口还包括设置于机壳10底部的底部出风口14，用于向壁挂式空调室内机1的前侧下方送风。壁挂式空调室内机1可单独通过离子风发生装置30驱动送风，也可以与风机类组件80相配合共同驱动送风。离子风发生装置30产生的离子风可以经过换热装置40换热后送出，也可不经换热装置40换热直接送出，以单独送风或与风机类组件驱动的气流相混合后送出。
在本发明的一些实施例中，参见图1和图2，至少部分出风口12呈圆形，每个圆形的出风口12处均设有用于整流送风的开闭机构20，每个开闭结构20均包括中央挡板21和多个曲形叶片22。
中央挡板21固定不动地设置于相应的一个出风口12的中央，其外周缘与相应的一个出风口12的内周缘之间形成出风区域。例如，上述中央挡板21可以为圆形，则相应的出风区域为环形。在本发明的一些替代性实施例中，上述中央挡板21可以为方形、椭圆形等其它形状。
多个曲形叶片22沿中央挡板21的周向依次设置，多个曲形叶片22配置成可以向中央挡板21的中心聚拢以至少部分地打开出风区域，并且可以完全聚拢收缩至中央挡板21的前侧或后侧。由此，可在壁挂式空调室内机1停机时，使得多个曲形叶片22向出风口12边缘展开，并可以完全封闭出风区域，能够有效防止外部的灰尘和杂质进入风道内部，从而保证了壁挂式空调室内机1的工作效果。在壁挂式空调室内机1工作时，多个曲形叶片22向中央挡板21的中心聚拢收缩，以完全打开出风区域，以便于壁挂式空调室内机1送风。
具体地，在一些实施例中，曲形叶片22的数量可以为6个，而且沿中央挡板21的周缘均匀地设置。在另外一些实施例中，叶片的数量还可以为6个以下或6个以上，具体可以根据叶片大小、中央挡板21的大小和出风口12大小进行设定。优选地，多个曲形叶片22可以完全聚拢收缩至中央挡板21的后侧，也就是说，多个曲形叶片22处于完全收拢状态时，中央挡板21 可以遮蔽多个曲形叶片22，用户无法从送风口外部观察到曲形叶片22，使得送风口处的外形更加美观。更为重要的是，多个曲形叶片22可以完全收拢至中央挡板21的后侧，不占用额外的风道空间，提高了壁挂式空调室内机1内部的空间利用率。多个曲形叶片22还可以向背离中央挡板21中心的方向展开以至少部分地封闭出风区域。多个曲形叶片22可以展开至完全覆盖上述环形出风区域，以实现送风口的全面封闭。
图6和图7分别是根据本发明一个实施例的开闭结构的曲形叶片的不同方位示意性结构图。在本实施例中，曲形叶片22近似成月牙形，其具有一外轮廓边缘部和一内轮廓边缘部，外轮廓边缘部呈凸形，内轮廓边缘部呈凹形。内轮廓边缘部在多个曲形叶片22聚拢时朝向中央挡板21的中心设置，则相应地，外轮廓边缘部在多个曲形叶片22聚拢时可朝向出风口12的内周缘。外轮廓边缘部和内轮廓边缘部共同限定出曲形叶片22的根端和末端。
如图6-7所示，在本发明的一些实施例中，每个曲形叶片22的外轮廓边缘部包括：第一圆弧形区段221和第二圆弧形区段222。内轮廓边缘部包括：第三圆弧形区段223和第四圆弧形区段224。第一圆弧形区段221和第四圆弧形区段224朝向曲形叶片22的根端逐渐靠近，从而使得曲形叶片22的根端形成渐缩的曲形区域。第二圆弧形区段222和第三圆弧形区段223朝向曲形叶片22的末端逐渐靠近，从而使得曲形叶片22的末端同样形成渐缩的曲形区域。也就是说，第一圆弧形区段221和第四圆弧形区段224沿指向曲形叶片22的根端的方向逐渐靠近，以使曲形叶片22的根端形成渐缩的曲形区域；第二圆弧形区段222和第三圆弧形区段223沿指向曲形叶片22的末端的方向逐渐靠近，以使曲形叶片22的末端形成渐缩的曲形区域。
在本发明的一些优选地实施例中，第一圆弧形区段221的曲率与中央挡板21的外周缘的曲率相等。也就是说，当多个曲形叶片22完全聚拢至中央挡板21后侧时，多个曲形叶片22的第一圆弧形区段221与中央挡板21的外周缘重合。在多个曲形叶片22聚拢后，每个曲形叶片22的部分区域位于与该曲形叶片22的相邻的两个曲形叶片22之间。第二圆弧形区段222的曲率与出风口12的内周缘曲率相等。也就是说，当多个曲形叶片22完全展开至覆盖出风区域时，多个曲形叶片22的第二圆弧形区段222与出风口12的内侧周缘重合。如此设计，多个曲形叶片22可以完全收拢至中央挡板21后侧或完全展开遮蔽出风区域，使得出风口12处的外形更加完整、美观。
另外，第三圆弧形区段223的曲率和长度与第一圆弧形区段221的曲率和长度均相等。在本实施例中，在多个曲形叶片22完全展开至覆盖出风区域时，相邻两个曲形叶片22的第一圆弧形区段221和第三圆弧形区段刚好拼合在一起，使得多个曲形叶片22能够完整地覆盖出风区域，同时相邻曲形叶片22之间尽可能不发生交叠，以充分利用曲形叶片的大小，使得送风口处的外形更加完整、美观。
在本发明的一些实施例中，为了便于多个曲形叶片22的聚拢和展开，每个曲形叶片22优选地绕其根端可转动地设置于中央挡板21的前侧或后侧。而且，在多个曲形叶片22聚拢后，每个曲形叶片22的部分区域位于与该曲形叶片的相邻的两个曲形叶片22之间。
进一步地，第一圆弧形区段221上还具有从邻近曲形叶片22根端向远离根端方向渐高的导向凸缘225，以在多个曲形叶片22收缩或扩展运动时，在室内机前后方向上对多个曲形叶片22进行导向，以便于多个曲形叶片22可至少部分重叠。这样设置是因为多个曲形叶片22在收拢的过程当中，相邻的曲形叶片22可能会发生机械干涉。上述导向凸缘225靠近根端的位置较低，远离根端的位置较高，在相邻的曲形叶片22收拢至相互叠加时，导向凸缘225可以引导相邻叶片朝向后侧略微移动，以使得相邻的曲形叶片22在开闭结构20的前后方向上错开，以防止机械干涉。
在本发明的一些实施例中，参见图2，设有开闭机构50的出风口12的数量为多个，壁挂式空调室内机1还包括与设有开闭机构50的出风口12一一对应设置的多个轴流风机60。具体地，离子风发生装置10的数量为一个，轴流风机60的数量为两个，两个轴流风机60分别设置在离子风发生装置10的横向两侧。
在图2中，X轴正方向指壁挂式空调室内机的前侧，Y轴正方向指向壁挂式空调室内机的右侧，Z轴正方向指向壁挂式空调室内机的上方。在壁挂式空调室内机1的进深方向上，至少部分出风口12的后侧均设有一导风结构70。优选地，具有开闭机构20的出风口12处设有导风机构70。
图8是根据本发明一个实施例的壁挂式空调室内机的导风结构的正面示意图。参见图8，每个导风结构70包括：转动环73和两个摆叶组件。
转动环73设置于机壳10内部且正对相应的一个出风口12设置，转动环73配置成可控地绕其中心轴线转动。转动环73的内周缘可与出风口12 的内周缘在壁挂式空调室内机1的上下及左右方向上重合，即转动环73的内周缘设置于出风口12的内周缘的后侧。
两个摆叶组件可间隔设置于转动环73上，每个摆叶组件包括摆叶驱动机构和多片摆叶74，多片摆叶74位于转动环的内侧，且每片摆叶74的根部均具有一自转轴741，自转轴741的末端可穿过一圆孔。摆叶驱动机构配置成驱动多片摆叶74绕各自的自转轴741同步自转。且两个摆叶组件的摆叶74也关于转动环73的上述一条直径对称设置，并且相互对称的两片摆叶74的自转轴741在同一条直线上。摆叶74大小可以根据出风区域的大小进行设定。
在本发明的一些实施例中，每个摆叶驱动机构可跟随转动环73旋转，且包括：曲形连杆、多个摇杆、曲柄以及连杆电机。
在本实施例中，转动环73的转动范围优选为0至90°。导风结构70的工作原理为：转动环73先转动至预设位置，以带动多片摆叶74的自转轴741运动到相对于水平面处于特定角度的位置，再根据用户需要调节摆叶74的自转角度。具体地，当用户需要空调室内机1上下方向出风时，转动环73先转动至0°。此时，自转轴741处于水平方向的位置，如图6中空调室内机1的右侧出风口12所示，此时，再驱动两个曲形连杆上下运动，带动多片摆叶74上下翻转。当多片摆叶74上翻时，出风口12则向上出风；当多片摆叶74下翻时，出风口12则向下出风。当用户需要室内机左右方向出风时，转动环73先转动至90°。此时，自转轴741处于竖直方向，如图6所示空调室内机1的左侧送风口，此时，再驱动两个曲形连杆运动，带动多片摆叶74左右翻转。当多片摆叶74左翻时，出风口12则向左出风；当多片摆叶74右翻时，出风口12则向右出风。
由此可见，本发明导风结构70的摆叶74可以绕其自转轴741自转，还可以跟随转动环绕转动环73的中心公转。在空调室内机1的使用过程中，用户可以先调节转动环73旋转，确定出风口12的扫风方向，例如上下扫风、左右扫风、斜45°扫风，再调节摆叶74自转进行扫风。或者，在转动环73转动的过程中，同时进行扫风，以可能地吹出自然风。本发明的摆叶74具有更加多样的摆动角度，用户可以更加自由地调节送风口的送风角度。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根 据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
