本发明提出一种风道组件100，其应用于暖风机（未图示）。
如图1至图4所示，在本发明风道组件100一实施例中，所述风道组件100包括：
蜗壳10；
蜗舌30，所述蜗舌30设于所述蜗壳10，且与所述蜗壳10形成风道70，所述风道70具有进风口71和出风口73；
贯流风轮50，所述贯流风轮50设于所述风道70内，将气流由所述进风口71引入所述风道70内，并将所述风道70内的气流由所述出风口73吹出；
所述蜗壳10包括第一蜗舌部11，所述蜗舌30包括第二蜗舌部31，所述第一蜗舌部11与所述第二蜗舌部31分别位于所述进风口71的两侧；同一横截面上，所述第一蜗舌部11之根部M到所述贯流风轮50轴心O的连线，与所述第二蜗舌部31之根部N到所述贯流风轮50轴心O的连线的夹角A的大小为110°-170°。
现以暖风机水平放置为例进行介绍。
具体地，蜗壳10包括第一蜗舌部11、第一导风板13、及相对设置的二第一固定板15，第一导风板13与第一蜗舌部11连接且沿第一蜗舌部11朝向风道70的出风口73延伸设置，二第一固定板15沿贯流风轮50的轴线方向布置且相对设置，第一蜗舌部11和第一导风板13固设于二第一固定板15之间。
蜗舌30包括第二蜗舌部31、第二导风板33，及相对设置的二第二固定板35，第二导风板33与第二蜗舌部31连接且沿第二蜗舌部31朝向风道70的出风口73延伸设置，二第二固定板35沿贯流风轮50的轴线方向布置且相对设置，第二蜗舌部31和第二导风板33固设于二第二固定板35之间。一第二固定板35与一第一固定板15固定连接，从而实现了蜗舌30与蜗壳10的固定连接。
本发明的技术方案，通过将第一蜗舌部11之根部M到贯流风轮50轴心O的连线，与第二蜗舌部31之根部N到贯流风轮50轴心O的连线的夹角A设置在110°-170°之间，优化了风道70结构，减少了二蜗舌部间隙的漏流，改善了漏流的流动状态，降低了漏流对贯流风轮50的冲击作用，从而使得贯流风轮50进风侧叶片通道的进风条件及贯流风轮50的内部流场得以有效改善，减小了贯流风轮50内部偏心蜗的尺度，改善了偏心蜗的形状和位置，使得偏心蜗变小、变圆、且靠近贯流风轮50的内边缘，进而增大了贯流风轮50内部的有效流通面积，且使得贯流风轮50的内部流场更加稳定，提高了风量。
需要说明的是，蜗壳10和蜗舌30可均由塑料材料通过注塑成型方式得到，亦可均由金属材料制成。
如图4所示，所述第一蜗舌部11与所述贯流风轮50之间的最小间距B为2mm-4mm。如此，优化了蜗壳10结构，优化了风道70结构，减少了第一蜗舌部11与贯流风轮50之间的漏流，改善了贯流风轮50的内部流场，改善了偏心蜗的状态，提高了风压。同时，漏流的减少，还可降低对贯流风轮50的冲击作用，降低了噪音。
如图4所示，所述第二蜗舌部31与所述贯流风轮50之间的最小间距C为2mm-4mm。如此，优化了蜗舌30结构，优化了风道70结构，减少了第二蜗舌部31与贯流风轮50之间的漏流，改善了贯流风轮50的内部流场，改善了偏心蜗的状态，提高了风压。同时，漏流的减少，还可降低对贯流风轮50的冲击作用，降低了噪音。
如图4所示，所述第一导风板13具有靠近所述出风口73和远离所述出风口73的两端，所述第一导风板13于其两端之间形成有朝向所述风道70的凸起部131。
可以理解的，凸起部131的设置，可改善风道70内部的流场，使得风道70内部的气流在经过凸起部131时，由于缩口效应，气流的风压和流速均得以提升。
进一步地，所述凸起部131设于所述第一导风板13靠近所述出风口73的一端，所述第二蜗舌部31之根部N到所述凸起部131的距离D为所述第二蜗舌部31之根部N到所述第一导风板13上任一点的距离之中最短。如此，可有效增强缩口效应，从而进一步提升风压和流速。
如图4所示，所述第二蜗舌部31之根部N到所述凸起部131的距离D，与所述出风口73的宽度E的比值为1:(2-2.5)。
这样，可进一步优化风道70结构，优化风道70内部的流场，使得出风口73处的气流流速更大、吹得更远，且噪音更低。
具体地，所述第二蜗舌部31之根部N到所述凸起部131的距离D为18mm-30mm，所述出风口73的宽度E为36mm-75mm。
如图2、图3、图4及图9所示，所述第一导风板13位于所述风道70外的表面和/或所述第二导风板33位于所述风道70外的表面设有线扣135。
本实施例中，第一导风板13位于风道70外的表面设置有若干线扣135，第二导风板33位于风道70外的表面亦设置有若干线扣135。这样，在风道组件100的实际应用过程中，线扣135可对贯流风轮50的驱动电机的电源线进行锁扣定位，并且，通过线扣135的有序排布，可对电源线的走线起引导作用，从而使得电源线的走线更加合理和有序，避免电源线触碰风轮而对风轮转动造成不良影响。
如图2、图3、图5至图8所示，所述蜗壳10具有沿所述贯流风轮50轴线方向设置的两端部，两端部分别设有安装孔151，所述蜗舌30的对应位置处设有安装柱351，所述安装柱351插设于所述安装孔151内。
本实施例中，蜗壳10的第一固定板15开设有安装孔151，相应地，蜗舌30的第二固定板35于其面向对应的安装孔151处凸设有安装柱351，安装柱351插设并卡持于安装孔151内，实现了第二固定板35与第一固定板15的固定连接，进而完成了蜗舌30于蜗壳10的安装。具体地，每一第一固定板15上开设有若干间隔设置的安装孔151，对应的第二固定板35上凸设有若干间隔设置的安装柱351，每一安装柱351插设并卡持于一安装孔151内，以实现固定，从而有效提高蜗舌30安装于蜗壳10的稳定性。可以理解的，这样的安装方式简单、可靠，不仅便于零部件的加工与制造，还有效节省了资源消耗和成本投入，实用性更高。
需要说明的是，每一安装柱的形状和大小与对应的安装孔相匹配，而各安装柱之间可相同，亦可不同。
本发明还提出一种暖风机（未图示），所述暖风机包括壳体（未图示）和设于所述壳体内的风道组件，所述风道组件是如前所述的风道组件100。由于本暖风机采用了前述所有实施例的全部技术方案，因此至少具有前述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
进一步地，如图2、图3及图9所示，所述风道组件100的蜗壳10和/或蜗舌30设有定位凸耳133，所述定位凸耳133开设有定位孔1331，所述暖风机的壳体设有定位柱（未图示），所述定位柱插设于所述定位孔1331内。
本实施例中，蜗壳10的第一导风板13和蜗舌30的第二导风板33上均设有定位凸耳133，其上的定位孔1331可用于风道组件100安装时与暖风机壳体的定位柱进行预安装工序，为后续安装起到的定位和导向作用，从而便于风道组件100于暖风机壳体的安装及固定，提升安装效率。
进一步地，如图1至图3所示，所述风道组件100的蜗壳10设有固定柱153，所述固定柱153朝向所述暖风机的壳体延伸设置，且固接于所述暖风机的壳体。
本实施例中，蜗壳10的二第一固定板15分别设置有一固定柱153，用于与暖风机的壳体固定连接，从而有效提升风道组件100安装稳定性、结构可靠性，防止整体震动，保障整机工作。可以理解的，固定柱153与壳体的固接方式，可采用螺钉连接方式、卡扣连接方式、胶接方式、销接方式、或其他合理且有效的方式。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
