在本发明的一些实施例中，如图2至图4所示，每个导风柱120绕穿过其的沿竖直方向延伸的旋转轴线可转动地设置。每个导风柱120可转动到封闭对应的第一出风口111的位置处，使得气流只通过两个第二出风口112从壳体的两侧吹出，具有环绕风的效果，如图4所示。每个导风柱120还可转动到使气流通过其两侧流动到第一出风口111的一个或多个位置处，如图3所示，气流通过导风柱的两侧流动后，分成两股气流，从第一出风口吹出，并在第一出风口的前侧交汇并混合，使得气流被打散，可防止直吹人。
在本发明的一些实施例中，每个出风风道170的连通第二出风口112的位置处转动设置有沿竖直方向延伸的导风板130，用于引导气流流向第一出风口111和/或第二出风口112。导风板130可转动到封闭对应的第二出风口112的位置处，以引导气流流向第一出风口111，如图3所示。
在本发明的一些实施例中，立式空调室内机100还包括两个横向导风装置，每个横向导风装置用于在前后和/或横向方向上引导流出一个第二出风口的气流。例如，横向导风装置为可移动设置的具有微孔的挡板，挡板可移动到封闭第二出风口112的位置。在一些替代性实施例中，横向导风装置为可转动设置的出风板，出风板可转动到封闭第二出风口112的位置。当然，横向导风装置也可为移动设置的出风格栅。第一出风口111和第二出风口112为椭圆形、长方形或正方形。第二出风口112的不同形状与挡板、出风板或出风格栅可自由组合，使得该实施例中的立式空调室内机100与传统的立式空调室内机相比，外观较为新颖，差异化明显，增强了产品竞争力。
在本发明的一些实施例中，立式空调室内机100通过温度传感器测量室内温度，并计算其与设定温度之间的温差的绝对值，最后与设定的温差阀值比较，调整立式空调室内机100的出风状态。在室内温度与设定温度之间的温差的绝对值大于或等于第一温差阀值时，导风柱120转动150度至180度，此时导风柱120远离第一出风口，且导风柱120沿横向方向延伸，第一出风口111的有效出风面积较大，导风板130处于打开状态，气流可通过第一出风口111和第二出风口112吹出，使得出风量较大，适用于室内的快速降温或升温的场景。当然，导风柱也可转动到其他角度的位置处，以使得第一出 风口可向不同的方向吹风，例如导风柱转动到90度位置处，此时第一出风口可向正前方吹风。
在室内温度与设定温度之间的温差的绝对值小于或等于第一温差阀值，且大于或等于第二温差阀值时，导风柱120转动到封闭对应第一出风口111的位置，且导风板130处于打开状态，气流从两个第二出风口112向两侧吹出，实现环抱风效果，如图4所示。
在室内温度与设定温度之间的温差的绝对值小于第二温差阀值时，导风柱120转动到远离第一出风口的位置，且导风柱120沿横向方向延伸，第一出风口111的有效出风面积较大，同时导风板130处于关闭状态，气流只通过第一出风口111吹出，可实现远距离送风，如图3所示。在不需要出风时，关闭立式空调室内机100，此时导风柱120转动到封闭第一出风口111的位置，且第二出风口112处于封闭状态，可防止灰尘等杂物进入，如图2所示。其中，第一温差阀值为2.5℃至3.5℃，优选地为3℃。第二温差阀值为0.5℃至1.5℃，优选地为1℃。
在本发明的一些实施例中，如图2至图4所示，每个出风风道170的从靠近第一出风口111的前端开始的至少部分区段从后向前呈渐缩状，使得气流具有聚合的效果，并且可使气流加压，出风更远。而且可以与导风柱120配合使用，以控制出风量或者关闭第一出风口111。
在本发明的一些实施例中，如图2至图4所示，旋转轴线处于两个曲线的高点的连线上，且靠近一个曲线的高点。两个曲线对称设置，以使外轮廓至少为轴对称图形。旋转轴线处于出风风道170的连通第二出风口112的位置处的前方。旋转轴线处于出风风道170内，以允许导风柱120转动一周。
在本发明的一些实施例中，外轮廓为椭圆形。外轮廓沿长度方向的距离与外轮廓沿厚度方向的距离之间的比值为1.8至2.2。优选地，外轮廓沿长度方向的距离与外轮廓沿厚度方向的距离之间的比值为2。
在本发明的一些实施例中，如图2至图4所示，每个出风风道170内设置有导风摆叶140，用于引导气流流向第一出风口111和/或第二出风口112。导风摆叶140可用于上下导风。
在本发明的一些实施例中，如图1至图4所示，壳体110的后侧设置有与两个出风风道170连通的进风口113。壳体110内设置有换热器150和两个风机160，换热器150靠近进风口113。每个风机160设置于一个出风风 道170内。每个风机160促使气流从进风口113进入壳体内，与换热器150进行热交换后形成换热气流，并从第一出风口111和/或第二出风口112吹出。风机160为贯流风机。
在本发明的一些实施例中，每个出风风道170的从靠近第一出风口111的前端开始的部分区段包括相对设置的第一导风面和第二导风面。每个第一导风面向远离另一出风风道170的方向拱起，每个第二导风面向靠近另一出风风道170的方向拱起，以使得每个出风风道170的从靠近第一出风口111的前端开始的至少部分区段从后向前呈渐缩状。每个所述第二出风口在所述第一导风面上与对应的所述出风风道连通。
第二导风面的前端处于第一导风面的前端的斜前方。第一导风面的前边缘处切面与沿横向方向延伸的竖直平面之间的夹角大于第二导风面的前边缘处切面与沿横向方向延伸的竖直平面之间的夹角。两个第一出风口111分别处于壳体110的前侧的横向两端。两个第二出风口112分别处于壳体的两侧的前端，使得气流能向两侧和斜前方吹出。
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。
