下面结合图1-图7描述本申请提供的立柜式空调内机的结构。
如图1至图2所示，本申请实施例提供的立柜式空调内机，其包括空调主体10和轴流扇20。轴流扇20固定安装在空调主体10的底部区域，该轴流扇20的出风方向沿水平方向。如图1所示，空调主体10对应于轴流扇20设置有若干出风口11。如图3所示，空调主体10靠近底部的位置设有室内风口12和/或室外风口13。
在本申请的一些实施例中，空调主体10靠近底部的位置仅设有室内风口12，室内气流从室内风口12进入，经轴流扇20从出风口11排出，借助轴流扇20促进室内空气的循环，有助于实现室内空气的均匀变化。在本申请的又一些实施例中，空调主体10靠近底部的位置仅设有室外风口13，室外气体从室外风口13进入，经轴流扇20从出风口11排出，借助轴流扇20向室内引入新风，促进室内与室外的空气循环，避免温度变化太快导致用户使用体验感下降。在本申请的再一些实施例中，空调主体10上同时设有室内风口12和室外风口13，室内风口12和室外风口13处均可拆卸地安装有密封盖，以便用户根据个人喜好选择打开室内风口12或室外风口13。
本申请实施例提供的立柜式空调内机，在空调主体10的底部设有室内风口12和/或室外风口13，相比于传统空调，在空调主体10底部形成新的风道，在空调制冷或制热时，安装在空调主体10内的轴流扇20可以有效促进室内空气循环，使室内空气温度均匀变化，提升用户的使用体验。
具体地，如图1所示，空调主体10包括立柱、侧板15和前饰板16。侧板15包括两个，每一侧板15的一侧通过螺钉和卡扣与立柱固定连接，侧板15的另一侧与前饰板16卡扣固定。出风口11设置在前饰板16上，轴流扇20固定安装在立柱和空调主体10的前蜗舌上。如图4至图6所示，前饰板16的内表面沿竖直方向的两侧边分别设有若干卡扣，借助卡扣将前饰板16与两个侧板15对接在一起。需要说明的是，前饰板16的内表面指的是前饰板16朝向空调主体10内部的一侧侧面，前饰板16的外表面指的是前饰板16与内表面相对的一侧侧面。
其中，如图4所示，前饰板16包括板体161及设置在板体161内表面的圆形风道162。圆形风道162与轴流扇20匹配，板体161对应于圆形风道162设有若干出风口11，板体161的内表面设置有若干导风筋163。 圆形风道162用于与轴流扇20配合，轴流扇20的出风端对应于出风口11。圆形风道162的宽度大于前饰板16中板体161的宽度。可以理解的，圆形风道162的宽度也可以小于板体161的宽度，本申请实施例不具体限定圆形风道162与板体161的相对宽度关系。当圆形风道162的宽度大于板体161的宽度时，圆形风道162朝向板体161的一侧呈封闭状，在该封闭段设置出风口11。对应的，在与前饰板16相连的两个侧板15的边缘设有弧形缺口，当侧板15与前饰板16卡扣固定后圆形风道162的边缘与侧板15的弧形缺口边缘抵接。当圆形风道162的宽度小于板体161时，侧板15无需设置弧形缺口，直接与板体161的直边对接即可。
如图4和图6所示，导风筋163呈弧形，若干导风筋163沿圆形风道162的中轴线呈辐射状排布，使气流呈螺旋状。借助弧形的导风筋163对圆形风道162内的气流进行二次螺旋混合，最终依靠压力从出风口11排入室内。具体地，相邻两导风筋163之间设置有多个出风口11，从轴流扇20排出的气流与导风筋163发生冲撞后从出风口11排出，提升空气循环流动的速度。导风筋163的弧形凹面方向一致，多个弧形的导风筋163绕圆形风道162的中心呈环形辐射状排布。
如图5和图6所示，若干出风口11中的一部分围绕圆形风道162的中轴线呈圆形排布，形成中心风口，若干出风口11的其他部分以中心风口为中心呈辐射状排布。借助中心风口集中气流，辐射状排布的其他出风口11可以将气流分散至各处，从而提升气流作用面积，提升空气循环流动效果。
优选的，辐射状排布的出风口11分为多组风口组，每组风口组包括多个沿圆形风道162径向排布的出风口，多组风口组沿圆形风道162的周向设有多条，相邻两组风口组所在的圆形风道的直径之间的夹角为30°～60°。在板体161的内表面，相邻两组风口组之间设置一条导风筋163。当气流在圆形风道162内通过出风口11向外流动时，通过导风筋163汇聚气流并借助中心风口和呈辐射状的其他出风口将吹出去，扩大气流流动时的覆盖面，有效促进室内空气循环。
在上述任一实施例的基础上，如图7所示，侧板15靠近前饰板16的一侧设有若干风轨151，风轨151用于将轴流扇20的侧方气流引导至中部。 具体地，风轨151由设置在侧板15边缘处的肋板结构形成，借助风轨151将轴流扇20边缘处的气流引导至侧板15，以提升轴流扇20的作用效果。
因地域差异，空调在制热或制冷过程中达到预设目标温度的时间不同，为适应不同地域，本申请实施例提供的立柜式空调内机，初始设置轴流扇20的启动时长为零，逐次收集用户启动后室内温度达到预设目标温度的时长，修正启动时长，当调整到位后，轴流扇20待室内温度达到预设目标温度后方启动，避免空调长时间运行导致室内空气循环流动性差的问题。
除此之外，本申请实施例还提供一种空调器，其包括如上所述的立柜式空调内机。该空调器中，立柜式空调内机可以促进空调流通或者通入新风，在空调器运行过程中实现辅助制冷和制热。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，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申请各实施例技术方案的精神和范围。
