本申请实施例提供的立柜式空调器，在主风道10的下方增设辅助风道100，辅助风道100内安装随主风扇20一起转动的贯流风扇，当立柜式空调器处于工作状态时，室内的空气经在贯流风扇的作用下从辅助风道100内流过，从而促进空气流动。
需要说明的是，本申请实施例提供的立柜式空调器中，辅助风道100为非标准件。
在上述实施例的基础上，如图2和图3所示，辅助风道100的进风口处还安装有电加热器200，电加热器200用于加热辅助风道100内流通的空气。当立柜式空调器处于制热模式时，电加热器200启动，辅助制热；当立柜式空调器处于制冷模式时，电加热器200不运行，借助辅助风道100和贯流风扇促进动室内空气流动以辅助制冷。
具体地，如图4和图5所示，本申请实施例中的辅助风道100包括顶 面101、底面102、第一侧面103及第二侧面104，顶面101与底面102相对设置并通过第一侧面103与第二侧面104相连形成供空气流通的流通通道。顶面101设有用于安装贯流风扇的风扇安装孔105，底面102设有用于安装贯流风扇转轴的安装座1021，第一侧面103设有向流通通道内凹陷的凹陷部106，流通通道的第一端作为进风口107，流通通道的第二端形成有第一出风口108与第二出风口109，其中，第一出风口108相比于第二出风口109更靠近第一侧面103。
其中，第一侧面103与第二侧面104相对，且流通通道因凹陷部106从进风口107向出风口存在突变区，顶面101与底面102相对设置，两者的面积可以大于第一侧面103和第二侧面104之间的间距，也即在顶面101和底面102向第一侧面103和第二侧面104的外侧延伸形成外沿。可以理解的，在另一实施例中，顶面101和底面102的一侧与第一侧面103对接，另一侧与第二侧面104对接，此时顶面101和底面102恰好封住第一侧面103和第二侧面104之间的间距。除此之外，辅助风道100还可以采用圆形风道，对此本申请实施例不做具体限定。
贯流风扇安装在风扇安装孔105处，用于将室内空气吸入流通通道。当主风扇20转动时，贯流风扇随之转动，室内空气沿流通通道分别从第一出风口108和第二出风口109排出。其中，第一出风口108和第二出风口109之间由与立柜式空调器的立柱300卡接的避让空间110隔开。在避让空间110的壁面上设置螺孔和/或卡扣结构，以便将辅助风道100固定在立柱300上。
具体的，如图4所示，凹陷部106包括第一弧面、过渡面及第二弧面，第一弧面相比于第二弧面更靠近进风口107。过渡面的一端与第一弧面平滑过渡，过渡面的另一端与第二弧面平滑连接，第一弧面、过渡面及第二弧面相连后大体呈几字型。其中，第一弧面凸向流通通道外部，过渡面凸向流通通道的内部，第二弧面凸向流通通道的外部。第一弧面和第二弧面的弧度可以一致或者不同。本申请实施例提供的凹陷部106在顶面101上的投影位于风扇安装孔105和第一出风口108之间，借助凹陷部106的凹陷将空气分流排出，确保第一出风口108和第二出风口109的空气排出量大体均衡。第一弧面和第二弧面可以为弧形面，也可以为一段平面与一段 弧形面对接形成的凹面。
进一步的，第一弧面与第二弧面关于过渡面对称设置，空气在流通通道内流动时经过凹陷部106发生湍流，改变空气流体的流动状态。
如图5所示，避让空间110包括相连接的第一壁面111与第二壁面112，第一壁面111为向流通通道内部凹陷的弧面，第二壁面112为平面。第一壁面111与第二弧面为同心弧面。第二壁面112与第二侧面104平行。第一壁面111、第二弧面、顶面101和底面102共同围设形成第一出风口108，第二壁面112、第二侧面104、顶面101和底面102围设形成第二出风口109。需要说明的是，避让空间110还包括连接面，该连接面位于第一壁面111和第二壁面112之间以连接第一壁面111和第二壁面112。
优选的，安装座1021为轴承安装座。组装时，轴承安装座内安装轴承，轴承的内圈与贯流风扇的转轴固定连接。
如图4所示，底面102靠近进风口107的一端设有加热器安装口1022，电加热器200从加热器安装口1022插接于流通通道内。可以理解的，加热器安装口1022由电加热器200的壳体密封。电加热器200包括电阻丝组，电阻丝组位于流通通道内。在制热模式下，电阻丝组发热，空气从进风口107进入后吸收电阻丝组释放的热量，辅助制热。当然，也可以将电加热器200安装在出风口端，对此不作具体限定。如图5所示，顶面101设有连接孔，电加热器200从加热器安装口1022插入流通通道内并通过插接在连接孔内的螺钉固定于顶面101。
其中，贯流风扇安装在风扇安装孔105，贯流风扇的一端通过联轴器与主风扇20相连，贯流风扇的另一端与安装座1021内的轴承固定连接。
在主风道10的底部设置有接水盘400，接水盘400位于辅助风道100上方。如图6和图7所示，接水盘400朝向主风道10凸设安装槽401，贯流风扇收容在安装槽401内并且贯流风扇的转轴穿过安装槽401的槽底与主风扇20的转轴相连。安装槽401与接水盘400的连接处设有倒角以实现平滑过渡。具体的，安装槽401的槽底设有贯穿孔402，贯流风扇的转轴穿过贯穿孔402通过联轴器与主风扇20的转轴相连。
本申请实施例提供的接水盘与传统的接水盘不同，接水盘400内设有安装槽401，安装槽401用于为贯流风扇提供容纳空间，贯穿孔402用于 供贯流风扇的转轴通过，在实现接水功能的同时为贯流风扇的安装提供空间。
接水盘400一体注塑成型。具体的，接水盘400采用ABS塑料或者PS塑料注塑成型。
如图6所示，接水盘400包括底板403及立沿404，立沿404沿底板403的周向环绕一圈形成接水槽。底板403的形状与立柜式空调器的外观形状适配。比如，圆柱式立柜空调器中底板403近似圆形，方形立柜空调器中底板403为方形。立沿404沿底板403的外缘绕设一圈，从而形成以底板403为槽底且以立沿404为槽壁的接水槽。
如图6所示，接水盘400的相对两侧分别设有避让槽405，避让槽405位于立沿404上并向接水槽内凹陷。两个避让槽405分别用于避让前立柱和后立柱。立沿404上设有螺孔及卡扣结构，以便将接水盘400固定在立柱300上。
底板403设有渐缩状的排水口406。排水口406的截面从接水槽的槽口向槽底方向逐渐缩小。如图7所示，排水口406向底板403外延伸形成连接部407，连接部407的周向设有外螺纹。底板403外指的是从底板403向接水槽外部延伸。连接部407连接接水管，以便将积水排出接水槽。
本申请实施例提供的立柜式空调器，在底部空间增设辅助风道100，辅助风道100结构简单，借助辅助风道100可以促进空气流动，提高空调器的制冷或制热效果。
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。
