实施例1
随着生活水平的提高，人们对风扇的功能、性能多样性需求也随之增加，对于能够带来舒适体验的风扇更为青睐。目前市面上的塔扇外观纤细，占地小，无外露叶片，安全系数更高；其多叶贯流风轮配合长行程风道，上下切风均匀，送风连续性好。但受限于塔式造型及较小的风轮直径，其对应出风口较窄，且贯流风道蜗壳大多采用阿基米德螺旋线或对数螺旋线设计，流体沿着螺旋线形成的切向方向送出，而靠近蜗壳形线位置处的风压会高于远离蜗壳位置处的风压，导致出风口靠近蜗壳的位置处的风速与远离蜗壳处的风速有差异，也即出风口左右两侧风速不均匀，且由于出风面积有限，送风范围较窄，导致用户体表温度均匀性较差。
为此，如图1至图10所示，本实施例提供一种贯流风道，能够提高送风范围。
在一个实施方式中，贯流风道包括蜗壳1和蜗舌2。蜗壳1包括第一本体101，第一本体101的第一侧为进风侧，第一本体101的第二侧为出风侧；蜗舌2与蜗壳1间隔设置，蜗舌2包括第二本体201，第二本体201的第一侧为进风侧，第二本体201的第二侧为出风侧，第一本体101及第二本体201之间构成适于安装风轮3的安装空间，第一本体101的第一侧与第二本体201的第一侧 之间构成进风口，第一本体101的第二侧与第二本体201的第二侧之间构成出风口，出风口包括若干第一出风开口和若干第二出风开口，第一出风开口和第二出风开口沿所述蜗壳的轴向间隔交错设置。
通过第一本体101和第二本体201间成型有出风口和进风口，通过将出风口分为沿所述蜗壳1的轴向间隔交错设置的第一出风开口和若干第二出风开口，进而构成多组不同方向的出风区域。第一本体101的第二侧设有多个沿蜗壳1的轴向间隔分布的第一导风板102，第一导风板102与所述第二本体间成型有所述第一出风开口，第二本体201的第二侧设有多个沿蜗壳1的轴向间隔分布的第二导风板202，第二导风板202与所述第一本体101间成型有所述第二出风开口；第一导风板102与第二导风板202在蜗壳1的轴向交错设置。可以定义蜗壳1所在侧为左侧，蜗舌2所在侧为右侧，则第一出风开口所在的左侧相对第二出风开口的左侧偏左，第二出风开口的右侧相对第一出风开口的右侧偏右，因此整体上扩大了出风宽度，提高了送风范围。
在上述实施方式的基础上，在一些实施方式中，第一导风板102包括第一板本体1021及设在第一板本体1021的端部且朝向安装空间的外侧延伸的第一导风面1022，第一板本体1021的第二侧还设有第二导风面103，第二导风面103朝向安装空间的外侧延伸；第二导风板202包括第二板本体2021及设在第二板本体2021的端部且朝向安装空间外侧延伸的第三导风面2022，第二板本体2021的第二侧还设有第四导风面203，第四导风面203朝向安装空间的外侧延伸。在该实施方式中，第一导风面1022、第二导风面103、第三导风面2022、第四导风面203的设置可以对出风方向进行引导，确保风朝向外侧吹，避免出风处气流紊乱。在一个可替换的实施方式中，可以分别将第一板本体1021的端面、第二板本体2021的端面、第一本体101的第二侧、第二本体201的第二侧分别设置引导斜面，通过引导斜面来对出风方向进行引导。
具体在一个实施方式中，可以使第一导风面1022、第二导风面103、第三 导风面2022、第四导风面203分别沿着风轮3的径向向外延伸。
在上述实施方式的基础上，在一些实施方式中，如图7所示，定义第一导风面1022与第二导风面103的中心对称面为第一面6，定义第三导风面2022与第四导风面203的中心对称面为第二面7，第一面6与第二面7的夹角为θ，0＜θ≤40°。在该实施方式中，第一面6与第二面7的夹角也为第一出风区域与第二出风区域的错位角。该实施方式通过限定第一出风区域与第二出风区域的错位角度，可以避免因错位角度过大而加剧贯流风道内部的气流速度及压力分布不均，而这种不均匀的气流作用在蜗舌2、蜗壳1和风轮3上，会形成气流压力随时间的脉动，风轮3的风叶旋转导致的气流脉动会连续周期性地冲击蜗舌2、蜗壳1等风道形体，增大旋转噪声的峰值，气流的不均匀性越大，会导致噪声越强，当错位过大。会破坏风轮3内部贯流连续性，还会产生明显的左右偏差风感，影响风道的风量及送风效果。因此，该实施方式通过限定第一出风区域与第二出风区域的错位角度，既能扩大出风宽度，提高送风范围，同时不会增加噪声，不会影响风道的风量。
具体在一个实施方式中，θ为40°。在一些可替换的实施方式中，θ为20°或30°。
在上述实施方式的基础上，在一些实施方式中，定义第一本体101的第二侧与第二本体201的第二侧的中心对称面为错位基准面5，第一面6和第二面7位于错位基准面5的两侧，第一面6与错位基准面5之间的夹角为θ1，第二面7与错位基准面5之间的夹角为θ2，0＜θ1≤20°，0＜θ2≤20°。作为可变换的实施方式，0＜θ1≤20°，θ2大于20°，或，θ1大于20°，0＜θ2≤20°。由于贯流风道蜗壳1弦线螺旋设置，出口处流体沿原本蜗壳1弦线切线喷出，因此在螺旋线延长段近蜗壳1背板方向处风速会高于远蜗壳1处，若第一出风区域、第二出风区域错位角度过大，会导致相邻节段风道风压梯度增大，从而使相邻的第一出风区域、第二出风区域出风风速不均匀，同时噪音及音质也会受到影响。 因此，该实施方式对第一面6与错位基准面5之间的夹角、第二面7与错位基准面5之间的夹角进行限定，也即对第一出风区域的中心与错位基准面5的夹角、第二出风区域的中心与错位基准面5的夹角进行限定，可以避免相邻的第一出风区域、第二出风区域出风风速不均匀，同时不会增大噪音，也可确保音质。
在上述实施方式的基础上，在一些实施方式中，第一本体101的第一侧设有多个沿蜗壳1的轴向间隔分布的第三导风板104。在该实施方式中，第三导风板104的设置可保证贯流风道的稳定。
在上述实施方式的基础上，在一些实施方式中，第二本体201的第一侧设有进风导风面204。在该实施方式中，进风导风面204与蜗壳1共同配合，使外界的空气顺利进入贯流风道中。进风导风面204为沿风轮3的径向延伸的斜面。
贯流风道还包括出风格栅4，出风格栅4设置在出风口处，且出风格栅4包括沿蜗壳1的轴向交错设置的第一格栅段401和第二格栅段402，第一格栅段401和第二格栅段402分别设有多个，且第一格栅段401的纵向中心对称面靠近第一本体101的第二侧，第二格栅段402的纵向中心对称面靠近第二本体201的第二侧。需要说明的是，纵向中心对称面为与风轮3的轴线共面。
在该实施方式中，通过将第一格栅段401和第二格栅段402交错设置，且第一格栅段401的纵向中心对称面靠近第一本体101的第二侧，第二格栅段402的纵向中心对称面靠近第二本体201的第二侧，第一格栅段401对应设置在所述第一出风开口上，所述第二格栅段402对应设置在所述第二出风开口上，第一本体101的第二侧处于左侧，第二本体201的第二侧处于右侧，因此可有效改善现有贯流风道送风范围较窄的问题，在保证塔扇贯流风道上下切风连线性的同时，实现更广范围送风，从而提高整机风感，提升用户舒适性体验。
在上述实施方式的基础上，在一些实施方式中，定义第一格栅段401的纵向中心对称面为第一中心对称面4011，第二格栅段402的纵向中心对称面为第二中心对称面4021，第一中心对称面4011与第二中心对称面4021的夹角为β，0＜β≤50°。第一中心对称面4011与第二中心对称面4021的夹角为第一格栅段401和第二格栅段402的错位角度，若第一格栅段401和第二格栅段402的错位角度过大会导致噪声及风量出现异常，因此，该实施方式对第一格栅段401和第二格栅段402的错位角度进行限定，可以在保证送风范围的前提下，不会增大噪声，确保风量。
在上述实施方式的基础上，在一些实施方式中，定义第一本体101的第二侧与第二本体201的第二侧的中心对称面为错位基准面5，第一中心对称面4011与错位基准面5之间的夹角为β1，第二中心对称面4021与错位基准面5之间的夹角为β2，0＜β1≤25°，0＜β2≤25°。作为可变换的实施方式，0＜β1≤25°，β2大于25°，或，0＜β2≤25°，β1大于25°。在该实施方式中，第一中心对称面4011与错位基准面5之间的夹角为第一格栅段401向左偏转的角度，第二中心对称面4021与错位基准面5之间的夹角为第二格栅段402向右偏转的角度。该实施方式对第一格栅段401、第二格栅段402的偏转角度进行进一步限定，可以在保证送风范围的前提下，不会增大噪声，确保风量。
在上述实施方式的基础上，在一些实施方式中，第一格栅段401和/或第二格栅段402的长度为C，1D/9≤C≤1D/4。若第一格栅段401、第二格栅段402的长度过短，会使其导风效果减弱，同时会使出口风压不足，风速会有所降低，影响风道送风效果；而若第一格栅段401、第二格栅段402的长度过长，则会增大格栅与送风流体之间的动静干涉，导致噪声峰值增高。因此，该实施方式对第一格栅段401、第二格栅段402的长度进行限定，可以在确保送风效果的同时不增大噪声。需要说明的是，第一格栅段401和第二格栅段402的长度为沿出风方向的长度。
在一个实施方式中，第一格栅段401和第二格栅段402的长度相等。在其他可替换的实施方式中，第一格栅段401的长度和第二格栅段402的长度不相等。
在上述实施方式的基础上，在一些实施方式中，贯流风道还包括设置在安装空间中的风轮3，风轮3的直径为D。在该实施方式中，蜗壳1、蜗舌2、风轮3、出风格栅4共同形成贯流风道。
在上述实施方式的基础上，在一些实施方式中，第二本体201的横截面为圆弧，第二本体201的轴线与风轮3的轴线共线。在该实施方式中，蜗舌2能够较好的引导气流，起到分流锥的作用。
在上述实施方式的基础上，在一些实施方式中，第二本体201与风轮3之间的径向最小距离为A，1D/28≤A≤1D/10。第二本体201与风轮3之间的径向距离蜗舌2为蜗舌2与风轮3的间隙，蜗舌2与风轮3的间隙和风轮3直径的比值大小对流量及效率的影响显著，且对贯流风道压力有一定的影响，间隙较大时，风机压力降低，流量减小，间隙减小时，压力升高，流量变大，但噪音峰值及音质也会变差，且会对后续贯流风道转配及风轮3安规等方面造成影响。因此，该实施方式对第二本体201与风轮3之间的径向最小距离进行限定，既能确保具有一定的压力及流量，又不会增加噪音及影响音质。
在上述实施方式的基础上，在一些实施方式中，第一本体101与风轮3的间距最小的位置为蜗喉105，蜗喉105与风轮3的间距为B，1D/22≤B≤1D/11。风轮3与蜗壳1的距离增加会导致风量下降，且会导致蜗壳1的第一侧处涡流区域逐渐增大，导流紊流噪音增大，而蜗喉105与风轮3的间距过小会加大风轮3内部气流风速及压力的不均匀性，增加蜗壳1周围区域的脉动力，使旋转噪声增大。因此，该实施方式对蜗喉105与风轮3的间距进行限定，可以确保风轮3内部风速及压力的均匀性，减小噪音。
在上述实施方式的基础上，在一些实施方式中，出风格栅4与风轮3之间的径向距离为F，1D/6≤F≤1D/3。若出风格栅4与风轮3之间的间距过小会增大风道出口的压力脉动，从而增大流场内宽频噪声，此外，过小的出口间隙会导致流场内流体过渡不均，造成风量损失，出口风速降低。因此，该实施方式对出风格栅4与风轮3之间的径向距离进行限定，可以防止风道出口的噪声较大，减少风量损失，确保出口风速的大小。
在上述实施方式的基础上，在一些实施方式中，如图2所示，风轮3包括多节风轮段301，相邻的两个第一格栅段401，或者，相邻的两个第二格栅段402，相邻的两个第一导风板102，或者，相邻的两个第二导风板202之间的距离为N节风轮段301的长度，1≤N≤3。
相邻的两个第一格栅段401之间的距离为第二格栅段402的高度，相邻的两个第二格栅段402之间的距离为第一格栅段401的高度，该实施方式对第一格栅段401的高度、第二格栅段402的高度进行限定，也即对格栅离散错位频率作出限定，贯流风道由于蜗壳1及蜗舌2作用会在风轮3流场内部形成漩涡，当旋涡偏离叶轮旋转轴线的中心引起贯流的产生；第一格栅段401、第二格栅段402高度过低会使出口处流场离散频率增大，影响风道内部风压，使单节段偏心涡位置无法稳定，不能在叶轮内部形成稳定的贯流区，相邻节段间流场紊乱，会对整机噪音、音质、出口风速及流量造成很大的影响；第一格栅段401、第二格栅段402高度过大，则会使流场错位幅度增大，导致相邻节段风道错位送风在较远处无法汇聚，产生明显的左右偏差风感，影响用户体验。因此，该实施方式对第一格栅段401的高度、第二格栅段402的高度进行限定，可以确保在叶轮内部形成稳定的贯流区，不会对整机噪音、音质、出口风速及流量造成影响，左右风速均匀。
实施例2

显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本公开创造的保护范围之中。
