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，仅用于解释本申请，而不能理解为对本申请的限制。
下面参考图1-图23描述根据本申请实施例的风道部件200，风道部件200可以设置于送风装置300。
如图1-图10所示，根据本申请实施例的风道部件200包括：风道本体201，风道本体201具有风道20111，风道20111具有风道送风口2019和进风接口2015，风道20111连通进风接口2015和风道送风口2019，风从进风接口2015流入风道20111，然后风道20111内的风从风道送风口2019吹出，风道20111相对于风道本体201的纵向截面500倾斜设置，如图3所示，风道本体201的纵向截面500与风道本体201的横向截面垂直，且纵向截面500与垂直于纸面的方向平行。
其中，需要说明的是，风道本体201的纵向方向是指图3中的上下方向，横向截面与水平面平行，风道20111相对于水平面倾斜设置，与现有技术相比，本申请的风道部 件200能够使风道20111倾斜设置，与现有技术相比，能够使风道20111倾斜，气流在风道20111内流动时，风道20111可以对气流起到导流作用，从而可以避免风道20111内产生涡流，进而可以降低风道部件200的工作噪音。并且，也可以使风道部件200的外观更加美观，从而可以促进风道部件200的外观发展，也可以促进送风装置300的外观发展，进而可以解决风道20111竖直布置限制了送风装置300的外观发展的问题。
由此，通过风道20111相对于风道本体201的纵向截面500倾斜设置，与现有技术相比，能够使风道20111倾斜，气流在风道20111内流动时，风道20111可以对气流起到导流作用，从而可以避免风道20111内产生涡流，进而可以降低风道部件200的工作噪音。
在本申请的一些实施例中，定义风道本体201的纵向方向为Z向，定义风道本体201的宽度方向为Y方向，定义风道本体201的厚度方向为X方向，并且X方向、Y方向和Z方向两两垂直，需要解释的是，图3中风道本体201的上下方向为Z向，图3中风道本体201的左右方向为Y方向，即图3中风道本体201的前后方向为X方向，其中，风道20111与由X方向和Z方向确定的ZX平面的夹角为α，需要说明的是，风道20111的风道20111内壁与ZX平面的夹角为α，如图5所示，随α角度的增加，出风风量减小，噪音增加量增大，出风风速与水平面的夹角变小，综合整机性能因素，应使得α满足：0＜α≤10°，优选地，α可以设置为3°，这样设置能够使风道20111与ZX平面的夹角更加适宜，气流在风道20111内流动时，可以避免风道20111内产生冲击噪声，从而可以降低风道部件200的工作噪音，并且，也可以将气流导向至风道送风口2019，从而便于风从风道送风口2019吹出。
在本申请的一些实施例中，定义风道本体201的纵向方向为Z向，定义风道本体201的宽度方向为Y方向，定义风道本体201的厚度方向为X方向，并且X方向、Y方向和Z方向两两垂直，其中，风道送风口2019与由Y方向和Z方向确定的ZY平面的夹角为β，需要说明的是，风道送风口2019的前端面与ZY平面的夹角为β，如图6所示，随β角度的增加，出风风量减小，噪音增加量增大，Z方向双气流相交梯度角变大，综合整机性能因素，应使得β满足：0＜β≤10°，优选地，β可以设置为1°，如此设置能够使风道送风口2019与ZY平面的夹角更加适宜，气流在风道20111内流动时，可以进一步避免风道20111内产生冲击噪声，从而可以进一步降低风道部件200的工作噪音，并且，也可以更好地将气流导向至风道送风口2019，从而更加便于风从风道送风口2019吹出。
在本申请的一些实施例中，风道20111的下端可以设置有进风接口2015，风可以从 风道20111的下端流入风道20111。
根据本申请的一个具体实施例，风道20111具有风道20111截面，风道20111截面可以与水平面平行，风道20111截面从风道20111的靠近进风接口2015的一端向着远离进风接口2015的一端递减，也可以理解为，如图3所示，在从下至上的方向上，风道20111截面逐渐递减，并且风道送风口2019的宽度变化趋势与风道20111的风道20111截面的变化趋势一致，也就是说，如图3所示，在从下至上的方向上，风道送风口2019的宽度逐渐递减，风道送风口2019的宽度方向是指图3中的左右方向。其中，当气流在风道20111内流动时，这样设置能够降低气流的能量损耗，可以使风道送风口2019的风速更加均匀，也可以降低风道送风口2019的出风噪音，还可以增大风道部件200的送风距离。
根据本申请的另一个具体实施例，风道20111具有风道20111截面，风道20111截面可以与水平面平行，风道20111截面从风道20111的靠近进风接口2015的一端向着远离进风接口2015的一端保持不变，也可以理解为，风道20111的风道20111截面的面积不变，风道送风口2019的宽度从风道送风口2019的靠近进风接口2015的一端向着远离进风接口2015的一端递减，也就是说，如图3所示，在从下至上的方向上，风道送风口2019的宽度逐渐递减，风道送风口2019的宽度方向是指图3中的左右方向。其中，当气流在风道20111内流动时，如此设置能够降低气流的能量损耗，可以使风道送风口2019的风速更加均匀，也可以降低风道送风口2019的出风噪音，还可以增大风道部件200的送风距离。
根据本申请的另一个具体实施例，风道20111具有风道20111截面，风道20111截面可以与水平面平行，风道20111截面从风道20111的靠近进风接口2015的一端向着远离进风接口2015的一端递减，也可以理解为，如图3所示，在从下至上的方向上，风道20111截面逐渐递减，风道送风口2019的宽度从风道送风口2019的靠近进风接口2015的一端向着远离进风接口2015的一端保持不变，也就是说，风道送风口2019的宽度不变，其中，当气流在风道20111内流动时，如此设置能够降低气流的能量损耗，可以使风道送风口2019的风速更加均匀，也可以降低风道送风口2019的出风噪音，还可以增大风道部件200的送风距离。
在本申请的一些实施例中，风道20111的靠近进风接口2015的一端的横截面积为S i，风道20111的远离进风接口2015的一端的横截面积为S o，需要解释的是，如图3所示，风道20111的下端的风道20111截面的横截面积为S i，风道20111的上端的风道20111截面的横截面积为S o，如图7所示，随S i/S o比值的增加，Z方向出风风速比逐渐 减小，Z方向上的出风风速比不宜过大也不宜过小，Z方向上的出风风速比过大或过小均会导致风道20111出风不均，噪声较大，因此应使得S i/S o满足关系式：1＜S i/S o＜2，优选地，S i/S o的比值为1.286，风道20111截面从风道20111的靠近进风接口2015的一端向着远离进风接口2015的一端的方向上，这样设置能够保证风道20111截面的面积逐渐递减，可以使风在风道20111内的流动速度更加均匀，可以降低风道20111内噪声，还可以使风道20111出风均匀，从而可以提升用户体验。
进一步地，风道送风口2019的靠近进风接口2015的一端的宽度为L i，风道送风口2019的远离进风接口2015的一端的宽度为L o，需要说明的是，如图3所示，风道送风口2019的下端的宽度为L i，风道送风口2019的上端的宽度为L o，如图8所示，L i/L o比值影响Z方向出风风速比，因使得整机性能风感较好，Z方向出风风速比应在0.7-2之间，因此L i/L o应满足关系式：L i/L o≥0.8S i/S o，在从下至上的方向，如此设置能够保证风道送风口2019的宽度逐渐递减，可以使从风道送风口2019吹出的风更加均匀，也可以提升风道部件200吹出风的风感效果。
具体地，L i和L o均可以设置为0.5-7mm，如图9和图10所示，随L i或L o的增加，风道20111风阻变小，风量增加，出风面积增加，L i或L o过大时会导致出风风速变小，L i或L o过小时会导致风量小，会使用户感觉没有风从风道部件200吹出。因此应使得0.5mm<L i或L o<7mm，例如：L i设置为4mm，L o设置为2mm，这样设置能够使L i和L o的值更加适宜，可以使从风道部件200的出风风速和风量适宜，从而可以使用户感觉有风从风道部件200吹出。
在本申请的一些实施例中，如图3所示，风道20111可以包括第一风道2011和第二风道2012，第一风道2011和第二风道2012均与进风接口2015连通，风可以从进风接口2015流入第一风道2011和第二风道2012，第一风道2011和第二风道2012关于风道部件200的纵向中线对称布置，风从进风接口2015流入风道20111时，如此设置能够使第一风道2011和第二风道2012的气流流量差值进一步变小，从而可以使第一风道2011和第二风道2012分配的风量更加均匀，进而可以降低风道部件200的气动噪声。
在本申请的一些实施例中，如图3所示，第一风道2011的上端与第二风道2012的上端的间隔距离值小于第一风道2011的下端与第二风道2012的下端的间隔距离值，如此设置能够保证风道20111相对于风道本体201的横向截面倾斜设置，可以使第一风道2011和第二风道2012的设置形式更加合理。
如图1-图14所示，根据本申请实施例的风道部件200包括：风道本体201，风道本体201内具有风道20111，风道20111具有风道送风口2019和进口端，进口端与进 风接口2015连通，在靠近进口端至远离进口端的方向上，风道送风口2019的横截面积逐渐减小。
现有风道部件的风道送风口为等宽设计，即在风道送风口的延伸方向上风道送风口的宽度不变，风在风道内流动时，在靠近风道的进口端至远离进口端的方向上，垂直于风道的横截面的风速逐渐减小，则气流动压变小，使得在靠近风道的进口端至远离进口端的方向上气流静压变大，导致风道送风口吹出的风速不均匀，增大风道送风口的出风噪声，并且，风从风道送风口吹出后，风的方向与水平面之间的夹角较大，风容易吹在用户的头部位置，使风感变差，影响用户使用体验。
在本申请中，风从进口端流入风道20111，在靠近进口端至远离进口端的方向上，风道20111内的风量逐渐减小，风从风道送风口2019吹出，由于风道送风口2019的横截面积逐渐减小，即风道送风口2019的宽度逐渐减小，风道送风口2019的宽度方向是指图13中的左右方向，与现有技术相比，在靠近进口端至远离进口端的方向上，风从风道送风口2019吹出时，能够使风道送风口2019的风速变化率减小，可以使从风道送风口2019吹出的风速更加均匀，从而可以降低风道送风口2019的出风噪声，并且，风从风道送风口2019吹出后，风的方向与水平面之间的夹角较小，风不容易吹在用户的头部位置，使风感变好，从而提升用户使用体验。
由此，通过风道送风口2019的横截面积逐渐减小，送风装置300工作时，能够使从风道送风口2019吹出的风更加均匀，可以降低风道送风口2019的出风噪音，从而可以提升用户体验。
在本申请的一些实施例中，风道20111可以沿风道部件200的高度方向延伸布置，风道部件200的高度方向是指图1中的上下方向，进口端可以设置于风道20111的下端，风道本体201的前部形成上下延伸的风道送风口2019，如此设置能够使送风装置300朝向送风装置300的前侧吹风，可以便于风吹到用户身上。
在本申请的一些实施例中，风道送风口2019的高度为H a处的风道送风口2019宽度为C,风道20111的高度为H b处的风道送风口2019宽度为D,满足关系式：当H b＜H a时，则C＜D，且0.1≤C/D≤1。其中，在靠近进口端至远离进口端的方向上，风道20111内的风量会逐渐减小，会使得风速变小，则气流动压变小，使得气流静压变大，最终使高度为H a处的风道送风口2019的风速与高度为H b处的风道送风口2019的风速之比V a’/V b’变大，风道送风口2019的风速不均匀，导致风道送风口2019噪声变大。
因此，在靠近进口端至远离进口端的方向上，通过风道送风口2019的横截面积逐渐减小，且0.1≤C/D≤1，风从风道送风口2019吹出时，能够使风道送风口2019的风 速变化率减小，即减小V a’/V b’的比值，可以使从风道送风口2019吹出的风速更加均匀，从而可以降低风道送风口2019的出风噪声，并且，风从风道送风口2019吹出后，能够进一步减小风的方向与水平面之间的夹角，可以保证风不容易吹在用户的头部位置，从而可以进一步提升送风装置300的风感，进而可以进一步提升用户使用体验。
进一步地，C/D的比值可以设置为0.5，风从风道送风口2019吹出时，这样设置可以使从风道送风口2019吹出的风速更加均匀，从而可以进一步降低风道送风口2019的出风噪声。
在本申请的一些示例中，如图12-图14所示，风道20111包括：风道内壁20192、风道外壁20193和与风道送风口2019相对的风道底壁20191，风道20111的内侧为风道内壁20192，风道20111的外侧为风道外壁20193，风道本体201的后部由风道底壁20191封闭，如此设置能够保证朝向风道20111的前侧吹风，可以使风从风道20111的前端吹出，从而可以避免风从风道底壁20191吹出，进而可以使风道20111的整体结构形式更加合理。
在本申请的一些示例中，风道内壁20192的前端和风道外壁20193的前端间隔开设置，如此设置可以在风道内壁20192和风道外壁20193之间形成风道送风口2019，从而可以保证风从风道20111内吹出。
在本申请的一些示例中，从靠近进口端至远离进口端的方向上，风道20111的横截面积逐渐减小。其中，现有送风装置的风道为等截面设计，即在风道的延伸方向上风道的横截面积不变，风在风道内流动时，在靠近风道的进口端至远离进口端的方向上，垂直于风道的横截面的风速逐渐减小，会导致风道内的风速不均匀，增加风道内噪声。而且在靠近进口端至远离进口端的方向上，由于垂直于风道的横截面的风速逐渐减小，则气流动压变小，使得气流静压变大，导致风道送风口吹出的风速不均匀，增大风道送风口的噪声。
而在本申请中，风从进口端流入风道20111，在靠近进口端至远离进口端的方向上，风道20111内的风量逐渐减小，风在风道20111内流动时，由于风道20111的横截面积逐渐减小，与现有技术相比，在靠近进口端至远离进口端的方向上，能够提升垂直于风道20111的横截面的风速，可以使风在风道20111内的流动速度更加均匀，从而可以降低风道20111内噪声。并且，在靠近进口端至远离进口端的方向上，由于垂直于风道20111的横截面的风速更加均匀，则气流动压变大，使得气流静压变化量变小，风从风道送风口2019吹出时，能够使从风道送风口2019吹出的风速更加均匀，可以降低风道送风口2019的出风噪声，从而可以提升用户体验。
根据本申请的一个具体实施例，如图14所示，从风道底壁20191至风道送风口2019方向，即图14中的由后向前方向，风道内壁20192与风道外壁20193之间的间隔距离先增大后减小，这样设置能够使风道20111具有整流作用，气流在风道20111内朝向风道送风口2019流动时，能够提升风道20111内的风道底壁20191至风道送风口2019方向的风速，可以增加风道送风口2019的吹风速度，从而可以增加送风射程，进而可以使送风装置300的风吹得更远。
根据本申请的另一个具体实施例，从风道底壁20191至风道送风口2019方向，风道内壁20192与风道外壁20193之间的间隔距离逐渐减小，如此设置能够使风道20111具有整流作用，气流在风道20111内朝向风道送风口2019流动时，能够进一步提升风道20111内的风道底壁20191至风道送风口2019方向的风速，可以进一步增加风道送风口2019的吹风速度，从而可以进一步增加送风射程，进而可以使送风装置300的风吹得更远。
如图1-图14所示，根据本申请实施例的风道部件200包括：风道本体201，风道本体201内具有风道20111，风道20111具有风道送风口2019和进口端，进口端与进风接口2015连通，在靠近进口端至远离进口端的方向上，风道20111的横截面积逐渐减小。
现有送风装置的风道为等截面设计，即在风道的延伸方向上风道的横截面积不变，风在风道内流动时，在靠近风道的进口端至远离进口端的方向上，垂直于风道的横截面的风速逐渐减小，会导致风道内的风速不均匀，增加风道内噪声。而且在靠近进口端至远离进口端的方向上，由于垂直于风道的横截面的风速逐渐减小，则气流动压变小，使得气流静压变大，导致风道送风口吹出的风速不均匀，增大风道送风口的噪声。
在本申请中，风从进口端流入风道20111，在靠近进口端至远离进口端的方向上，风道20111内的风量逐渐减小，风在风道20111内流动时，由于风道20111的横截面积逐渐减小，与现有技术相比，在靠近进口端至远离进口端的方向上，能够提升垂直于风道20111的横截面的风速，可以使风在风道20111内的流动速度更加均匀，从而可以降低风道20111内噪声。并且，在靠近进口端至远离进口端的方向上，由于垂直于风道20111的横截面的风速更加均匀，则气流动压变大，使得气流静压变化量变小，风从风道送风口2019吹出时，能够使从风道送风口2019吹出的风速更加均匀，可以降低风道送风口2019的出风噪声，从而可以提升用户体验。
由此，通过风道20111的横截面积逐渐减小，送风装置300工作时，能够使从风道送风口2019吹出的风更加均匀，可以降低风道送风口2019的出风噪音，也能够使风在 风道20111内的流动速度更加均匀，可以降低风道20111内噪声，从而可以提升用户体验。
在本申请的一些实施例中，风道20111可以沿风道部件200的高度方向延伸布置，风道部件200的高度方向是指图1中的上下方向，进口端可以设置于风道20111的下端，风道送风口2019可以设置于风道20111的前端，如此设置能够使送风装置300朝向送风装置300的前侧吹风，可以便于风吹到用户身上。
在本申请的一些实施例中，在风道20111的高度为Ha处的横截面积为S a,在风道20111的高度为H b处的横截面积为S b，满足关系式：H b＜H a，S a＜S b，0.1≤S a/S b≤1。其中，在靠近进口端至远离进口端的方向上，风道20111内的风量会逐渐减小，若S a＝S b，会使得横截面积为S a处的垂直于横截面积S a的风速V a小于横截面积为S b处的垂直于横截面积S b的风速V b，横截面积S a和横截面积S b之间的间隔距离越远，V b/V a的值越大，会导致风道20111内风速不均匀，增加风道20111内噪声，而且风道20111内由于靠近进口端至远离进口端的方向上方向风速变小，则气流动压变小，使得气流静压沿横截面积S b至横截面积S a的方向变大，最终使横截面积S a处的风道送风口2019的风速与横截面积S b处的风道送风口2019的风速之比V a’/V b’变大，风道送风口2019的风速不均匀，导致风道送风口2019噪声变大。因此，在靠近进口端至远离进口端的方向上，通过将风道20111设置为变截面，风在风道20111内流动时，能够使V b/V a和V a’/V b’的比值均变小，可以均匀风道20111内的风速，也可以使风道送风口2019的风速更加均匀，从而可以降低风道20111内以及风道送风口2019处的噪音。
进一步地，S a/S b的比值可以设置为0.75，这样设置能够更好地均匀风道20111内的风速，也可以进一步使风道送风口2019的风速更加均匀，从而可以进一步降低风道20111内以及风道送风口2019处的噪音。
在本申请的一些实施例中，如图12-图14所示，风道20111可以包括：风道内壁20192、风道外壁20193和与风道送风口2019相对的风道底壁20191，风道20111的内侧为风道内壁20192，风道20111的外侧为风道外壁20193，风道本体201的后部由风道底壁20191封闭，如此设置能够保证朝向风道20111的前侧吹风，可以使风从风道20111的前端吹出，从而可以避免风从风道底壁20191吹出，进而可以使风道20111的整体结构形式更加合理。
根据本申请的一个具体实施例，如图14所示，从风道底壁至风道送风口方向，即图14中的由后向前方向，风道内壁20192与风道外壁20193之间的间隔距离先增大后减小，这样设置能够使风道20111具有整流作用，气流在风道20111内朝向风道送风口 2019流动时，能够提升风道20111内的风道底壁20191至风道送风口2019方向的风速，可以增加风道送风口2019的吹风速度，从而可以增加送风射程，进而可以使送风装置300的风吹得更远。
根据本申请的另一个具体实施例，从风道底壁20191至风道送风口2019方向，风道内壁20192与风道外壁20193之间的间隔距离逐渐减小，如此设置能够使风道20111具有整流作用，气流在风道20111内朝向风道送风口2019流动时，能够进一步提升风道20111内的风道底壁20191至风道送风口2019方向的风速，可以进一步增加风道送风口2019的吹风速度，从而可以进一步增加送风射程，进而可以使送风装置300的风吹得更远。
在本申请的一些实施例中，通过风道外壁20193最前端的切线与风道送风口2019的宽度水平中线的夹角为G 1,满足关系式：0°≤G 1≤45°。需要说明的是，宽度水平中线是指风道送风口2019的在风道送风口2019宽度方向上的中线，风道外壁20193最前端的内壁面处的切线与宽度水平中线之间的夹角为G 1，这样设置能够避免风在风道送风口2019处产生涡流，可以保证送风装置300的送风距离，也可以进一步降低风道送风口2019处的气流噪音。
