附图说明
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解，这些附图未必是按比例绘制的。附图中：

具体实施方式
图1是根据本发明一个实施例的柜式空调室内机100的示意性剖视图。参见图1，柜式空调室内机100可包括开设有机壳进风口和机壳出风口的机壳110、设置于机壳110内的送风组件、以及设置于送风组件的进风流路上的换热组件。
机壳110可由底座和设置于底座上的机身围成，机身可包括前面板、导流延伸板115、两个横向侧板以及后背板。其中机壳进风口可形成于后背板。导流延伸板115可设置于前面板的下方，机壳出风口可包括由导流延伸板115的顶端与前面板的底端围成的下部出风口116。
送风组件可配置为从机壳进风口的周围环境吸入环境空气并促使空气向机壳出风口流动。
在一些实施例中，送风组件可包括离心风机121和离心风机122、用于容纳并支撑离心风机121和离心风机122的风道主体123、两个风道护板和出风框130。
离心风机121和离心风机122可均为横置的双吸式离心风机。离心风机121可配置为向上送风。离心风机122可设置于离心风机121的下方且配置为向下送风。
风道主体123可形成有两个互相隔离且反向延伸的风道部。每个风道部均包括与一个离心风机的蜗壳外壁形配的容置段和将该离心风机吹出的气流导出的导流段。其中每个风道部的两个横向侧壁对应风机进风口的位置处分别形成有一个气流入口。上侧风道部的顶端和下侧风道部的底端各形成有一个气流出口。
出风框130可设置于风道主体123的下方，并与下侧风道部连通，以将离心风机122吹出的气流导向下部出风口116。在一些实施例中，出风框130的顶部周缘处可形成有环状导流槽，用于收集自风道主体123123流下的冷 凝水。
两个风道护板可设置于风道主体123的横向两侧，并与风道主体123共同围成离心风机121和离心风机122的回风通道。室内换热器140可设置于回风通道内。
图2是图1中导风构件的示意性剖视图，其中出风框部件220处于打开位置；图3是图1中导风构件的示意性剖视图，其中出风框部件220处于闭合位置。参见图2和图3，空调室内机100还可包括导风构件200，用于接收由风道主体123的上侧风道部吹出的气流并将该气流经由前面板、两个横向侧板及后背板围成的顶部开口导向室内环境。
导风构件200可包括底壁和顶壁分别开设有进风开口2111和出风开口2112的壳体210、固定于壳体210内且进风口与进风开口2111对接的连通风道230、出风框部件220、以及用于驱动出风框部件220在打开位置和闭合位置之间转动的驱动装置。其中壳体210的进风开口2111可设置为与上侧风道部的气流出口对接。
图4是图2中出风框部件220的示意性侧视图；图5是图4所示的出风框部件220的示意性爆炸视图。参见图4和图5，出风框部件220可包括形成有风道的出风框221，用于接收自连通风道230吹出的气流。出风框221可设置为将连通风道230的出风口罩设在其风道内，当出风框221运动至打开位置时，出风框221的出风口经由壳体210的出风开口2112及机壳110的顶部开口显露于机壳110的上方，与上侧风道部、连通风道230共同形成连续的导风通道，将气流向前导出；当出风框221运动至闭合位置时，出风框221完全处于壳体210内，以在空调不工作时降低整机重心。
在一些实施例中，出风框部件220还可包括固定于出风框221的进风口处的密封圈225，以在出风框221处于打开位置时密封出风框221与连通风道230之间的间隙。
出风框部件220可设置为绕一固定于壳体210后部的定轴转动。定轴可位于出风框221的风道后侧，以增大出风框221的风道绕定轴旋转的转动半径，进而减小出风框221处于打开位置时与连通风道230之间的间隙，进而减小导风构件200的整体尺寸。
连通风道230可设置为自下向上并向前延伸，以进一步减小出风框221处于打开位置时与连通风道230之间的间隙。
图7是图2中驱动装置的示意性爆炸视图。参见图7，驱动装置可包括齿轮241、与齿轮241驱动连接的电机242、固定电机242的安装盒243。出风框部件220还可包括与出风框221固定连接的限位件222。限位件222形成有用于与齿轮241啮合的弧形齿条2222，以限定出风框221的运动路径。
本发明的柜式空调室内机100将形成有弧形齿条2222的限位件222固定于出风框221、将电机242固定于壳体210，相比于将弧形齿条2222固定于壳体210、电机242固定于出风框221，避免了因电机242本身的振动与出风框221的窜动叠加而加剧齿轮241振动，进而提高了出风框221运动的稳定性，延长了齿轮241和弧形齿条2222的使用寿命。
在一些实施例中，为避免因出风框221受热膨胀使齿轮241与弧形齿条2222咬合过量甚至卡死现象的发生，出风框221与定轴配合的枢转孔可设置为可相对于定轴在定轴的径向方向上窜动，以实现弧形齿条2222位置的自动调节。
图6是图5中限位件222的示意性侧视图。参见图6，限位件222可包括用于与出风框221固定连接的安装板2221和弧形齿条2222。弧形齿条2222可设置为自安装板2221向靠经齿轮241的方向延伸，且其垂直于安装板2221的表面形成有齿。
在一些实施例中，限位件222还可包括肋板2223。肋板2223可与弧形齿条2222相对设置，并将齿轮241夹置在其与弧形齿条2222之间。安装盒243可形成有向限位件222延伸的防脱止挡和防卡止挡。弧形齿条2222和肋板2223可设置于防脱止挡和防卡止挡之间，以防止齿轮241与弧形齿条2222脱离啮合关系或齿轮241与弧形齿条2222咬合过量。
防脱止挡和防卡止挡可分别设置有至少一个滚轮2432。每个滚轮2432的转动轴线可与齿轮241的转动轴线平行，并与对应的止挡转动连接，以减小出风框221的运动阻力。
限位件222还可包括连接弧形齿条2222和肋板2223的顶端的上侧限位板2224以及连接弧形齿条2222和肋板2223的底端的下侧限位板2225。安装盒243还可形成有自安装齿轮241的安装孔的顶部周缘处和底部周缘处向靠近限位件222的方向拱起的挡板2431。上侧限位板2224可配置为在出风框221运动至闭合位置时与挡板2431接触配合，以避免出风框221向下转动过位。下侧限位板2225可配置为在出风框221运动至打开位置时与挡板 2431接触配合，以避免出风框221向上转动过位。
在本发明中，限位件222和驱动装置的数量优选为两个，以进一步提高出风框221运动的稳定性。两个限位件222分别与出风框221的两个横向侧板固定连接。每个驱动装置的齿轮241设置为与一个限位件222的弧形齿条2222啮合。
两个驱动装置的齿轮241可均设置于两个限位件222之间，即每个限位件222的弧形齿条2222均向靠近另一限位件222的方向延伸，以避免灰尘落入齿间增加运动阻力。
在一些实施例中，出风框部件220还可包括两个横向饰板223。每个横向饰板223可与出风框221的一个横向侧板固定连接，并覆盖部分限位件222，以进一步避免灰尘落入齿间增加运动阻力。
在一些实施例中，出风框部件220还可包括顶盖224。顶盖224可设置为与出风框221固定连接，并在出风框221处于闭合位置时关闭机壳110的顶部开口，防止灰尘落入机壳110内。
每个横向侧板可包括饰板主体2231和翻边2232。其中饰板主体2231可设置为与出风框221的一个横向侧板固定连接并覆盖部分限位件222。翻边2232可设置为自饰板主体2231的顶部向远离出风框221的方向延伸，并与出风框221卡固。顶盖224可设置为与翻边2232卡固，以提高顶盖224的稳定性并避免顶盖224鼓凸。
顶盖224和两个横向饰板223可与出风框221留有间隔，以在出风框221与顶盖224、横向饰板223之间形成空腔隔温带，避免环境空气直接接触出风框221而在出风框221的外表面产生冷凝水。空腔内还可设置隔热垫，以进一步避免出风框221的外表面产生冷凝水。
在一些实施例中，出风框部件220还可包括设置于出风框221的出风口处的横摆叶组226和竖摆叶组227，用于分别在竖直方向上和横向方向上调节气流的流动方向。其中，横摆叶组226可设置于竖摆叶组227的前侧。
柜式空调室内机100还可包括分别设置于送风组件的横向两侧的四根立柱。立柱的底部可设置为与底座固定连接，前面板、两个横向侧板和后背板可合围于四根立柱。
两个风道护板出风框130可设置为与风道主体123紧固连接。风道主体123可设置为穿过两个风道护板与四根立柱紧固连接，以使送风组件稳定可 靠地固定在机壳110内。壳体210可设置为与四根立柱紧固连接。
空调室内机100还可包括设置于送风组件下方的新风装置170和主控板。新风装置170可将室外空气引入回风通道内，再通过离心风机吹送至室内环境，以提高室内的空气质量。
本发明还包括另一实施例，该实施例与前述实施例的区别在于导风构件200不包括壳体210，定轴、驱动装置可直接固定于机壳110，连通风道230可与风道主体123制成一体件。
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。
