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。
