具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。

下面参考附图描述本申请实施例的空调器风道结构100。
根据本申请实施例的一种空调器风道结构100，如图1所示，包括：风机支架3、第一风轮组件1和第二风轮组件2。
其中，如图2所示，风机支架3上形成有第一风机安装孔31和第二风机安装孔32。
如图1所示，第一风轮组件1包括第一风轮11，如图2所示，第一风轮11安装在第一风机安装孔31处，风机支架3上位于第一风轮11的出风侧形成有混风腔101(混风腔101的结构如图4所示)。
如图3所示，第二风轮组件2包括第二风轮21，第二风轮21安装在第二风机安装孔32处。因此第一风轮21所在的前后两侧形成第一风道，第二风轮21的前后两侧形成第二风道，构成双风道结构。
如图4所示，第二风轮21的进风方向和第二风轮21的出风方向形成夹角。这里的夹角可以为锐角，也可以为直角、钝角。
如图4所示，第二风轮21朝着第一风轮11的方向送风，当第一风轮11和第二风轮21同时工作时，第二风轮21的出风与第一风轮11的出风在混风腔101中进行混合出风。即，第一风轮11和第二风轮21共用一个出风口进行出风。
由上述结构可知，本申请实施例的空调器风道结构100，第二风轮21朝着第一风轮11的方向送风并进入混风腔101，混风腔101对第二风轮21的出风形成了一定的缓冲，第一风轮组件1和第二风轮组件2的出风在混风腔101处进行混风后再向外送出，使得出风的风感舒适。
第二风轮组件2的第二风轮21进风方向与出风方向形成一定的夹角，使第二风轮21将进风侧远离第一风轮11的风驱动并改变流动方向，进而向着第一风轮组件1处吹 动，因此进风侧各处的风均能受到较好的驱动和引导，再汇合至混风腔101混风后送出。
可以理解的是，当第一风轮组件1和第二风轮组件2安装的较远，两组风轮组件对应的进风端相距较远，进风侧所连通的进风空间较大时，第一风轮组件1对远离第一风轮11前侧的进风空间的风的驱动较弱，此时第二风轮组件2则可将该部分进风空间中的风驱动并导向第一风轮组件1，一方面加快了风的导流，提高了空调器风道结构100对进风和出风的循环效果；另一方面有效提高了出风混流效果，使出风集中，风感均匀舒适。
在一些示例中，第一风轮11和第二风轮21之间的中心距在350mm到800mm之间，从而保证进风侧的风均能受到较好的驱动。
当第一风轮组件1选择不同种类的风机时，可形成多种出风模式，满足多种出风需求。具体的，在一些示例中，当第一风轮11为轴流风轮，第二风轮21为离心风轮时，第二风轮21的出风快速地流向第一风轮11的出风侧，由于轴流风轮的出风强度大，出风距离远，轴流风轮的出风快速带动离心风轮的出风在混风腔101进行混合，因此当两股风向空调器1000的出风口301吹出时，不仅具有远距离送风的效果(中部的出风送风距离最远)，也具有出风时较大的广散性，使得出风口301边缘的出风送风范围更大，且风感舒适。可选的，轴流风轮直径150mm到400mm之间。离心风轮直径250mm到400mm之间。
在一些示例中，第一风轮11为斜流风轮，第二风轮21为离心风轮。同样的，斜流风轮将其进风侧的风以一定的离心速度和轴向速度向混风腔101吹送，而离心风轮将其对应的进风侧的风快速的甩入第一风轮11的出风侧，两股风在混风腔101中叠加、混合、形成扰流，向空调器1000的出风口301吹出，同样可形成具有一定送风距离的出风，且风感舒适，送风范围广。
在本申请的一些实施例中，如图5、图6所示，第一风轮组件1还包括：第一电机12和导风圈13。其中，第一电机12驱动第一风轮11转动。
导风圈13围绕第一风轮11的周向设置，混风腔101的至少一部分由导风圈13内部限定。即，导风圈13内所限定的部分空间或全部空间形成为混风腔101的至少一部分，当导风圈13内的部分空间形成为混风腔101的一部分时，导风圈13的外部也具有一部分混风腔101，用于混风。
可选的，如图5所示，导风圈13为圆筒形的。
可选的，如图7所示，导风圈13在远离风机支架3的方向上直径缩小。
如图7所示，导风圈13形成有多个，多个导风圈13沿轴向方向依次可拆卸连接， 多个导风圈13内限定出混风腔101。即混风腔101形成在导风圈13的内部，当第二风轮21向第一风轮11送风时，两股风在导风圈13内部形成混合，并沿着导风圈13所延伸的方向向外送出。本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。
有利的，如图7所示，多个导风圈13之间嵌套设置，相邻的导风圈13之间形成为导风进风口131，第二风轮组件2的出风可以经由导风进风口131进入到混风腔101，并与第一风轮组件1的出风混合后，排出。
可选的，如图10所示，导风圈13与空调器的出风口301之间间隔开设置，导风圈13与出风口301之间的空间限定出混风腔101的至少一部分。也就是说，导风圈13与出风口301之间的空间构成完整的混风腔101，或者导风圈13与出风口301之间的空间仅仅形成为混风腔101的一部分。
再参照图6所示，第一风机安装孔31处设有电机安装架14，电机安装架14包括电机安装板141和多个肋板142，多个肋板142的一端周向连接在电机安装板141上，多个肋板142的另一端连接在风机支架3上，第一电机12设在电机安装板141上。电机安装板141的设置，为第一电机12提供了相对稳定的安装环境，使得第一电机12在驱动第一风轮11旋转时工作稳定。而多个肋板142将电机安装板141稳定地连接在风机支架3上，且肋板142之间的间隙使得第一风轮11顺利吸入进风侧的风。
可选的，如图6所示，第一风轮组件1还包括电机盖板15，电机盖板15压设在第一电机12上。电机盖板15将第一电机12限位在电机安装板141上，防止第一电机12脱出。另外，电机盖板15将第一风轮11和第一电机12之间压紧，使第一电机12的电机轴与第一风轮11的旋转轴之间形成紧密的连接。
在本申请的一些实施例中，如图5和图6所示，第二风轮组件2还包括：第二电机22和蜗壳23。
其中，第二电机22驱动第二风轮21转动。
而蜗壳23罩设在第二风轮21上。蜗壳23将第二风轮21罩在内部形成的空间用于将第二风轮21的出风导向第一风轮11的出风侧。
具体的，蜗壳23包括蜗壳出风口231，蜗壳出风口231朝向混风腔101。出风口231的设置，使被蜗壳23汇聚并导流的风集中从出风口231向外送出。
在本申请的一些实施例中，如图5所示，风机支架3上还设有聚风板4，聚风板4围绕导风圈13设置。即，聚风板4设在导风圈13的周向，聚风板4的至少部分和导风圈13之间形成一定的间隙。聚风板4可增大混风时的混风区域，也可使第一风轮11 的出风和从第二风轮21送来的风均聚集在聚风板4围成的区域内，提高混风效果和出风的集中程度。
可选的，如图5所示，导风圈13的轴向长度小于聚风板4的在前后方向上的长度，混风腔101的至少一部分由聚风板4长于导风圈13的部分构成的腔体限定出。即，由导风圈13导流送出的风在聚风板4靠近出风口301的处与第二风轮21送来的风进行混合。
可选的，如图5所示，聚风板4包括第一侧板41和第二侧板42，第一侧板41和第二侧板42设在第一风轮组件1的相对两侧，第一侧板41和第二侧板42之间限定出接合口44，第二风轮21的出风从接合口44送入聚风板4之间的腔体中。此时，进入聚风板4之间的腔体中的风可以与导风圈13中送出的风混合，也可以从第一侧板41和第二侧板42相对设置时的上部空间导出，向着出风口301的上部送出。
进一步的，如图5所示，聚风板4包括第三侧板43，第三侧板43连接在第一侧板41和第二侧板42的一端，第一侧板41、第二侧板42、第三侧板43围合在第一风轮组件1的周向。此时，第一侧板41、第二侧板42、第三侧板43围合形成的腔体的前部靠近出风口301处形成混风腔101，导风圈13内的空间连通聚风板4之间的空间。
可选的，再参照图4所示，蜗壳出风口231与接合口44相接，聚风板4与导风圈13之间的腔体限定出周缘出风腔45。周缘出风腔45连通了蜗壳23内的出风，由蜗壳23送入周缘出风腔45的风环绕在导风圈13的周侧流动，并向着聚风板4的前侧混风腔101流动，不干扰第一风轮11的转动，且由第二风轮21吹来的风在周缘出风腔45得到了较好的缓冲。
在本申请的描述中，限定有“第一”、“第二”、“第三”的特征可以明示或者隐含地包括一个或者更多个该特征，用于区别描述特征，无顺序之分，无轻重之分。
下面参考附图描述本申请实施例的空调器1000。
根据本申请实施例的一种空调器1000，如图9、图10所示，包括：空调器风道结构100、换热器200和面板300。
其中，空调器风道结构100为前述的空调器风道结构100，其结构在此不做赘述。
换热器200形成在空调器风道结构100的进风侧，换热器200与空调器风道结构100之间形成负压腔201，负压腔201使外部的风在经过换热器200时进行充分的热交换，且换热快速，进风风量大。
面板300设在空调器风道结构100的出风侧，面板300上对应第一风轮组件1处设有出风口301。第一风轮11和第二风轮21吹出的风形成的混合风混合后从出风口301 送出。
因此具有上述结构的空调器1000，经过换热器200换热后的风进入负压腔201后，在空调器风道结构100的驱动和导流下，在混风腔101进行混风，最终从对应第一风轮组件1的出风口301向外送风，风感舒适(风感舒适的原因如前所述)，送风模式可调。
具体的，此处送风模式可调是指，第一风轮11和第二风轮21可以同时开启或仅开启第一风轮11和第二风轮21中的一个。两者同时开启的情况如前所述，此处不再赘述。
当第一风轮11开启而第二风轮21不开启时，则出风口301吹出的风仅为第一风轮11产生的风，因此，送风距离足够远，送风量稍小。
当第一风轮11不开启而第二风轮21开启时，则出风口301吹出的风主要为第二风轮21产生的风，因此风感柔和，送风量较小。当第二风轮21持续向外送风，则第一风轮11出风侧的部分风被带走并从出风口301送出，第一风轮11被动转动，增加送风量，节省电量。
在本申请的一些实施例中，出风口301形成为环状，导风圈13的外缘与出风口301相接。此处的导风圈13内送出的风从出风口301的中部吹出。
在一些示例中，面板300上设有与周缘出风腔45对应的凸出部。此时，导风圈13的外缘与出风口301相接，聚风板4的边缘搭在凸出部上，由此周缘出风腔45中的风直接向出风口301送出，或进入导风圈13内与第一风轮11吹出的风在混风腔101中混合后再向出风口301送出。
为更好理解本申请实施例的方案，下面结合附图描述本申请的具体实施例。
