具体实施方式
下面详细描述本公开的实施例，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，旨在用于解释本公开，而不能理解为对本公开的限制。
下文的公开提供了许多不同的实施例或例子用来实现本公开的不同结构。为了简化本公开的公开，下文中对特定例子的部件和设置进行描述。当然，它们仅仅为示例，并且目的不在于限制本公开。此外，本公开可以在不同例子中重复参考数字和/或字母。这种重复是为了简化和清楚的目的，其本身不指示所讨论各种实施例和/或设置之间的关系。此外，本公开提供了的各种特定的工艺和材料的例子，但是本领域普通技术人员可以意识到其他工艺的可应用于性和/或其他材料的使用。
下面，参照附图，描述根据本公开实施例的风道组件。
如图1和图2所示，风道组件包括：上游风道部1和贯流风道部2，上游风道部1限定出上游风道11，在贯流风道部2的横截面上，贯流风道部2包括间隔开设置的第一风道壁21和第二风道壁22，第一风道壁21和第二风道壁22之间形成贯流风道23，贯流风道23连通在上游风道11的下游，第一风道壁21包括蜗舌段211，贯流风道23包括形成在蜗舌段211的蜗舌迎风面2a与第二风道壁22之间的风轮安装腔231，第一风道壁21的位于蜗舌段211的蜗舌舌尖2b与贯流风道23的风道出口232之间的部分为出风段212。例如，蜗舌段211还包括蜗舌导风面2c，蜗舌导风面2c与蜗舌迎风面2a通过曲面平滑过渡相连以形成蜗舌舌尖2b。
如图1和图2所示，风轮安装腔231用于安装贯流风轮5，其中，贯流风道部2的横截面指的是，采用与贯流风轮5的中心轴线相垂直的平面截贯流风道部2所得的横截面。在贯流风轮5转动时，引发气流流经上游风道11，由上游风道11流出的气流，从贯流风道23的风道入口进入贯流风道23，之后通过风道出口232排出到贯流风道23外。风轮安装腔231位于贯流风道23的风道入口处。
如图1和图2所示，风道组件上具有补气路径3，补气路径3的进气口31位于出风段212，且进气口31与贯流风道23的位于风轮安装腔231的下游的区域(例如图1中所示的第一区域233)连通。补气路径3的出气口32设于蜗舌段211与上游风道部1之间，且朝向贯流风道23外敞开，且与上游风道11连通，从而出气口32可以在风轮安装腔231的上游的相对靠近蜗舌段211的位置，向贯流风道23之外的上游风道11送出气流，气流而后再从上游风道11流向贯流风道23，即从出气口32送出的气流可以先进入上游风道11、再进入贯流风道23。
需要说明的是，另外，出气口32的朝向不限，只要不朝向贯流风道23内部敞开即可。值得说明的是，本文所述的某特征的上游，指的是气流进入某特征之前的位置，某特征的下游，指的是气流流出某特征之后的位置。
由此，出气口32的气压可以小于进气口31的气压，从贯流风轮5流出的一部分气流，当到达进气口31处时，可以在气压的作用下被进气口31吸入，然后通过出气口32排出到贯流风道23之外，以位于风轮安装腔231外的上游，而后再通过贯流风道23的风道入口进入贯流风道23、继而进入风轮安装腔231，从而对贯流风道23内的位于风轮安装腔231靠近蜗舌段211处的偏心涡进行控制，有效地改善贯流风道23的进气效率，从而提升贯流风道23的抗压性能，进而提升贯流风道23的风量。
申请人在研究中创造性地发现，当将补气路径3的出气口32相对靠近蜗舌段211设置，并朝向贯流风道23外敞开且与上游风道11连通时，从出气口32排出的气流可以先进入上游风道11、再吸入贯流风道23，此时结合图3，该股气流可以较为有效地沿偏心涡的周向或切向，冲击偏心涡的边缘，从而提高偏心涡的驱动效率，改善贯流风道23的进气效率，提升贯流风道23内的气体流动性能，提升贯流风道23的抗压性能，进而提升贯流风道23的风量。
而且，随着贯流风轮5的转速不同，蜗舌段211处形成的流场随之变化，补气路径3 的气流可以随转速自适应变化，稳定且适应性地对偏心涡进行有效控制，更加有效地改善贯流风道23的进气效率，提升贯流风道23内的气体流动性能，提升贯流风道23的抗压性能，提升贯流风道23的风量。
此外，值得说明的是，申请人在研究中还创造性地发现，如果将补气路径3的出气口32设置在蜗舌迎风面2a上，以朝向贯流风道23内敞开(图未示出该示例)，从而补气路径3则直接与贯流风道23内部连通，从补气路径3排出的气流则会从蜗舌迎风面2a，直接流入到贯流风道23内的蜗舌迎风面2a与贯流风轮5之间的较小间距处，并大体直接沿偏心涡的径向冲击偏心涡，这样，不但无法对偏心涡进行有效控制，而且还会使得偏心涡更加阻碍贯流风道23内的气流流动，导致贯流风道23的抗压性更弱，致使贯流风道23的风量降低。
简言之，根据本公开实施例的风道组件，通过设置补气路径3，补气能够随贯流风轮5的转速变化、以及蜗舌段211的自身特性，自适应调节偏心涡的流动特性，改善贯流风道23的进气效率，从而提升贯流风道23的流动性能，提升贯流风道23的风量。
在本公开的一些实施例中，上游风道11内可以设置换热器6，以包括用于安装换热器6的换热器安装腔111，由此，如图1和图2所示，在贯流风轮5转动时，引发气流流经上游风道11，气流进入上游风道11内与换热器6换热后，流出至贯流风道23，之后通过风道出口232排出到贯流风道23外。
需要说明的是，换热器6的具体类型不限，只要具有换热功能即可，例如，可以包括管翅片式换热器、微通道换热器、电阻换热器等等。另外，在一些实施例中，上游风道11内也可以不设置换热器6，例如可以什么都不设置，或者设置其他功能件，例如，导风件、过滤件、净化件、加湿件等等。
如图1和图2所示，当上游风道11包括用于安装换热器6的换热器安装腔111时，出气口32可以设于蜗舌段211与换热器安装腔111之间，且与上游风道11的位于换热器安装腔111的下游的区域(例如图1中所示的第二区域112)连通。
可以理解的是，从贯流风轮5流出的气流在到达风道出口232之前可以先到达第一区域233的位置，从换热器6流出的气流在进入贯流风道23之前可以先到达第二区域112，第一区域233处的压力大于第二区域112处的压力，从而进气口31处的气流可以在气压的作用下吸入补气路径3，并通过出气口32排出到第二区域112，随后进入贯流风道23内。
简言之，由于出气口32的气压小于进气口31的气压，从贯流风轮5流出的一部分气流，当到达进气口31处时，可以在气压的作用下被进气口31吸入，然后通过出气口32排出到上游风道11的位于换热器6下游的位置，以在后续吸入贯流风道23时，对贯流风道23内的位于风轮安装腔231靠近蜗舌段211处的偏心涡进行控制，有效地改善贯流风道23的进气效率，从而提升贯流风道23的抗压性能，进而提升贯流风道23的风量。
相关技术中的一些分体挂壁式空调器，为了提升换热能力，采用整体式C型翅片的换热装置(例如图1中所示的换热器6)，相对于采用V型翅片的换热装置而言，换热能力可以提升10％以上，但是，对风道流体性能而言，C型翅片的压力损失会加大。例如经过 测试，C型翅片的出口截面最大风速为3.5m/s，而V型翅片的出口截面最大风速为4m/s。C型翅片的总压降为17.7Pa，V型翅片的总压降为12.7Pa，由此可见，C型翅片的压降更大，压力损失较大，导致进风阻力增大，进风不顺畅。而且，在制冷状态下，由于翅片上会积水，导致进风阻力进一步增大，进风更加不顺畅，在同转速下，风量会锐减，局部风速过小。
当分体挂壁式空调器采用贯流风轮时，在贯流风轮工作时，会在贯流风轮的靠近蜗舌处形成偏心涡(例如4图中所示的X处)，降低贯流风道的抗压性，而且，在贯流风道的风道入口外附近靠近蜗舌的一端，由于贯流风道的流动特点，易在这里形成一个低压涡旋(例如图4中所示的Y处)，降低贯流风道的进气效率。并且，由于分体挂壁式空调器的一些其他需求，通常会在低压涡旋处设置结构端壁、例如接水盘等，从而会进一步恶化贯流风道的进气效率，使得贯流气流的流动不稳定，影响贯流风道的进气效率。
而根据本公开实施例的风道组件，通过设置补气路径3，补气能够随贯流风轮5的转速、以及蜗舌段211的自身特性，自适应调节偏心涡和低压漩涡的流动特性，有效地改善贯流风道23的进气效率，提升贯流风道23内的气体流动性能，提升贯流风道23的抗压性，提升贯流风道23的风量。
在本公开的一些实施例中，风道组件可以包括：下游风道部，下游风道部限定出下游换热风道，下游换热风道连通在贯流风道的下游，下游换热风道包括用于安装换热装置(包括但不限于是上文所述的换热器6)的下游安装腔。由此，在贯流风轮5转动时，引发气流流经上游风道11，而后流经贯流风道23，之后再进入下游换热风道，气流进入下游换热风道内与换热装置换热，之后排出下游换热风道。此时，上游风道11内可以什么都不设置，也可以设置功能件，例如，导风件、过滤件、净化件、加湿件、换热器6等等。另外，在其他一些实施例中，风道组件也可以不包括下游风道部。
值得说明的是，补气路径3的进气口31和出气口32可以是重合的(例如可以直接打穿一个板作为补气路径3，该穿孔既为进气口31、又为出气口32)，当然，本公开不限于此，补气路径3的进气口31和出气口32也可以是不重合的，例如进气口31和出气口32可以通过补气通道33、或密封空腔34、或导气硬管、或导气软管等连通。
在本公开的一些实施例中，补气路径3的出气口32可以位于蜗舌迎风面2a的远离风轮安装腔231的一侧。值得说明的是，本文所述的“远离风轮安装腔231的一侧”都指的是远离贯流风轮5的一侧，特征一位于特征二的远离风轮安装腔231的一侧，指的是，特征一与贯流风轮5之间的径向距离，大于特征二与贯流风轮5之间的径向距离。
因此，“补气路径3的出气口32位于蜗舌迎风面2a的远离风轮安装腔231的一侧”指的是，即补气路径3的出气口32位于蜗舌迎风面2a附近，且出气口32与贯流风轮5之间的径向距离，大于蜗舌迎风面2a与贯流风轮5之间的径向距离。由此，可以避免补气路径3的出气口32位于蜗舌迎风面2a的朝向风轮安装腔231的一侧表面上，而是可以保证出气口32相对蜗舌迎风面2a远离风轮安装腔231设置，从而可以避免从出气口32流出的气流直接从蜗舌迎风面2a流出而直接进入贯流风道23内，而是从出气口32流出的气流可以先 进入贯流风道23外的上游风道11，之后再进入贯流风道23。由此，可以更加有利于对贯流风道23的进气效率起到正面影响。当然，本公开不限于此，在本公开的其他实施例中，也可以将出气口32设置成与蜗舌迎风面2a的相对位置关系不那么明确，这里不作赘述。
在本公开的实施例中，出气口32的数量以及形成位置不限，例如，出气口32包括第一出口、第二出口和第三出口中的至少一种，第一出口形成在第一风道壁21上，第二出口形成在上游风道部1上，第三出口形成在第一风道壁21与上游风道部1之间的间隙处。也就是说，出气口32可以形成在第一风道壁21上、上游风道部1上、第一风道壁21与上游风道部1之间中的至少一处。由此，可以针对不同机型进行相应的出气口32设计，提高适用范围，并且可以简化加工。
可选地，出气口32为至少一个，当出气口32为多个时，多个出气口32沿远离风轮安装腔231的方向依次间隔开设置，任一出气口32可以为一个开口，或者可以包括沿贯流风道23的轴向间隔开排列的多个子出口。同理，进气口31为至少一个，当进气口31为多个时，多个进气口31沿出风方向依次间隔开设置，任一进气口31可以为一个开口，或者可以包括沿贯流风道23的轴向间隔开排列的多个子进口。
当出气口32为多个时，例如，可以是出气口32包括第一出口、第二出口和第三出口中的至少两种，每种出气口32的数量为至少一个，再例如，还可以是出气口32包括第一出口、第二出口和第三出口中的一种，且该种出气口32的数量为至少两个。
例如，第一出口可以为一个或者多个，当第一出口为多个时，多个第一出口沿远离贯流风轮5的方向依次间隔开设置，任一第一出口可以为一个开口，或者包括沿贯流风道23的轴向间隔开排列的多个第一子出口。
例如，第二出口可以为一个或者多个，当第二出口为多个时，多个第二出口沿远离贯流风轮5的方向依次间隔开设置，任一第二出口可以为一个开口，或者包括沿贯流风道23的轴向间隔开排列的多个第二子出口。
例如，第三出口可以为一个开口，或者包括沿贯流风道23的轴向间隔开排列的多个第三子出口。
例如在一些实施例中，蜗舌段211还包括蜗舌延伸面2d，蜗舌延伸面2d由蜗舌迎风面2a的远离蜗舌舌尖2b的一端起，朝向远离风轮安装腔231的方向延伸(结合图1和图2)，第一出口设于蜗舌延伸面2d上。由此，直接在蜗舌段211上加工第一出口即可，加工方便，降低成本，且第一出口相较蜗舌迎风面2a可以远离贯流风轮5，从而提高对偏心涡的驱动效率，可以更加有效地改善进气效率。
例如在一些实施例中，蜗舌段211还包括蜗舌延伸面2d，蜗舌延伸面2d由蜗舌迎风面2a的远离蜗舌舌尖2b的一端起，朝向远离风轮安装腔231的方向延伸(结合图1和图2)，蜗舌延伸面2d的远离蜗舌迎风面2a的一端与上游风道部1之间限定出第三出口。由此，第三出口的形成简单，加工方便，降低成本，且第三出口相较蜗舌迎风面2a可以远离贯流风轮5，从而提高对偏心涡的驱动效率，可以更加有效地改善进气效率。
例如在一些实施例中，如图7和图8所示，蜗舌迎风面2a的远离蜗舌舌尖2b的一端与 上游风道部1之间限定出第三出口。由此，第三出口的形成简单，加工方便，降低成本。
在本公开的一些实施例中，如图1和图2所示，贯流风道23的中心线沿横向延伸，即贯流风轮5的中心轴线水平或大体水平设置，上游风道部1包括限定出接水槽121的接水段12，接水段12的至少部分位于换热器安装腔111与风轮安装腔231之间(例如图1中所示的第二区域112)的下方，出气口32位于接水段12的靠近蜗舌段211的一侧(例如图1和图2中所示的接水段12的右侧)。
由此，补气不易吹出接水槽121内的水，降低风吹水的问题。并且，通过将出气口32设在接水段12的靠近蜗舌段211的一侧，从而保证从出气口32排出的气流，可以较为有效地对贯流风道23内靠近蜗舌段211处的偏心涡进行控制，提升贯流风道23的抗压性，进而提升贯流风道23的风量。
如图1和图2所示，出气口32可以形成在蜗舌段211上、接水段12上、蜗舌段211和接水段12之间的间隙中的至少一处。当出气口32形成在蜗舌段211上(例如设在上述蜗舌延伸面2d上)，可以为上述第一出口的一个可选实施例，当出气口32形成在接水段12上，可以为上述第二出口的一个可选实施例，当出气口32形成在蜗舌段211和接水段12之间的间隙处(例如设在上述蜗舌延伸面2d的远离蜗舌迎风面2a的一端与接水段12之间，如图9所示；或者设在上述蜗舌迎风面2a的远离蜗舌舌尖2b的一端与接水段12之间，如图7和图8所示)，可以为上述第三出口的一个可选实施例。由此，方便加工和制造，且可以简单且有效地保证出气口32位于接水段12的靠近蜗舌段211的一侧，保证补气不易吹出接水槽121内的水，降低风吹水的问题。
在本公开的一些实施例中，如图2、图5和图6所示，补气路径3包括用于连通出气口32与进气口31的补气通道33，补气通道33沿着从进气口31向出气口32的方向延伸，且出气口32、进气口31、补气通道33一一对应连通。也就是说，一个补气通道33仅与一个进气口31和一个出气口32连通，从而使得一个出气口32、一个进气口31、与一个补气通道33构成一个补气组，一个补气组中的出气口32和进气口31通过补气通道33连通，补气路径3包括至少一个补气组。由此，可以提升补气流通效率，降低补气损失。
可选地，补气通道33的宽度小于贯流风轮5的半径，从而可以实现较为有效地补气效果。或者可选地，补气通道33的宽度小于进气口31和出气口32中任一个的宽度的2倍，且大于进气口31和出气口32中至少一个的宽度的0.5倍。由此，只需开较小尺寸的补气通道33，即可实现快速补气引流，提高补气效率，降低风量损失，保证出风量。
结合图2，进气口31的宽度d1指的是，在垂直于贯流风道23的中心线的横截面上，进气口31的开口尺寸；出气口32的宽度d2指的是，在垂直于贯流风道23的中心线的横截面上，出气口32的开口尺寸，补气通道33的宽度尺寸d指的是，在垂直于贯流风道23的中心线的横截面上，补气通道33的宽度。
例如在一些实施例中，补气通道33的宽度可以为3mm-7mm，例如可以为3mm、4mm、5mm、6mm、7mm等等，由此，可以更好地兼顾补气效果和整体出风量。
值得说明的是，补气通道33的宽度可以是等宽度，也可以是渐变宽度的，例如补气通 道33可以加工为沿着从进气口31到出气口32的方向渐缩的形式，从而可以增大风量。再例如补气通道33可以加工为沿着从进气口31到出气口32的方向渐扩的形式，从而可以降低噪音。当补气通道33的宽度是等宽度时，可以兼顾风量和噪音，且方便加工。
具体而言，当分体挂壁式空调器采用贯流风轮时，为了兼顾制冷和制热效果，在制冷模式下，使得风能尽量往上吹，在制热模式下，使得风能尽量往下吹，同时防止空调器出风口的风回流到空调器进风口，在设计风道的风道出口时，有意识地扩压段上型线下压，导致扩压段内局部形成低速区，低速区不足以克服风道内部静压，存在风道出口外的气体回流入风道出口内引起脉动喘振音的发生，影响用户的使用感受。
值得说明的是，补气通道33的形状不限，例如，补气通道33从进气口31到出气口32，可以沿直线、或曲线、或直线与直线的结合、或直线与曲线的结合延伸。也就是说，在贯流风道部2的横截面上，补气通道33的延伸中心线的形状不限，可以为直线(此时，补气通道33为直线型通道，例如图2所示)、或曲线(此时，补气通道33为弧线型通道、例如图5所示，或波浪型通道、例如图6所示，等)、或直线与直线的结合(例如，补气通道33为折线型通道、或锯齿型通道等)、或直线与曲线的结合等等。
其中，沿直线延伸的补气通道33可以提高对偏心涡的控制能力，补气冲击速度强劲，同等贯流风轮5转速下，风量有所提升；而沿非直线，如曲线(如弧线、波浪线)、锯齿线等延伸的补气通道33，可以减缓补气冲击速度，风量和噪音变化不大，但是可以稳定气流流动。
在本公开的一些实施例中，补气路径3仅包括补气通道33，而不包括后文所述的密封空腔34，此时，出气口32、进气口31、补气通道33的数量可以相同且一一对应连通，也就是说，出气口32、进气口31、补气通道33的数量相同，可均为N个，N为大于等于1的整数，各出气口32分别通过一个对应的补气通道33与一个对应的进气口31连通。
如上文所述，任一出气口32可以为一个开口，或者包括沿贯流风道23的轴向间隔开排列的多个子出口，因此，一个补气组中的补气通道33存在同时与多个子出口连通的可能。另外，任一进气口31可以仅为一个开口，或者包括沿贯流风道23的轴向间隔开排列的多个子进口，因此，一个补气组中的补气通道33存在同时与多个子进口连通的可能。
其中，任一补气通道33可以为一个通道、或者包括沿贯流风道23的轴向间隔开设置的多个子通道。贯流风道23在贯流风道23的轴向上的延伸方向不限，取决于该补气通道33所需连通的进气口31和出气口32的相对位置。例如，在贯流风道部2的纵截面上(其中，贯流风道部2的纵截面指的是，采用过贯流风轮5的中心轴线的平面截贯流风道部2所得的纵截面)，连通的出气口32、进气口31和补气通道33，在贯流风道23的轴向上的位置对应。也就是说，补气通道33向纵截面作正投影，出气口32向纵截面作正投影，进气口31向纵截面作正投影，这三个正投影在贯流风轮5的轴向上的范围相同，由此，进入进气口31的气流无需沿贯流风道23的轴向偏移，即可从出气口32送出，从而进一步简化补气通道33的构造，降低加工难度，提高补气效率。
当然，本公开不限于此，在本公开的其他实施例中，出气口32、进气口31和补气通道 33，在贯流风道23的轴向上的位置还可以不对应，例如，出气口32对应贯流风道23的轴向一端，进气口31对应贯流风道23的轴向另一端等等，由此，进入进气口31的气流需要沿贯流风道23的轴向偏移，才可从出气口32送出，这里不再赘述。
在本公开的一些实施例中，如图10所示，补气路径3可以包括用于连通出气口32与进气口31的密封空腔34，密封空腔34同时与多个出气口32连通，和/或同时与多个进气口31连通。由此，可以满足不同的设计要求，实现灵活设计。
例如可选地，一个密封空腔34与一个进气口31连通，同时与多个出气口32连通，此时，气流可以从一个进气口31进入密封空腔34，然后从多个出气口32分成多股排出。再例如可选地，一个密封空腔34与多个进气口31连通，同时与一个出气口32连通，此时，气流可以从多个进气口31进入密封空腔34，然后从一个出气口32排出。又例如可选地，一个密封空腔34与多个进气口31连通，同时与多个出气口32连通，此时，气流可以从多个进气口31进入密封空腔34，然后从多个出气口32分成多股排出。
值得说明的是，补气路径3可以仅包括补气通道33和密封空腔34中的一者，也可以同时包括补气通道33和密封空腔34两者。由此，可以实现灵活设计。例如在一些可选实施例中，补气路径3仅包括密封空腔34、而不包括补气通道33，此时，全部出气口32和全部进气口31均可以与同一个密封空腔34连通，由此，可以简化设计，降低加工难度。
在本公开的一些可选实施例中，密封空腔34相比于补气通道33而言，可以不具有延伸方向性，密封空腔34相对补气通道33，宽度可以稍微大一些，例如，密封空腔34的至少部分的宽度可以大于进气口31和出气口32中至少一个的宽度的2倍等等，由此，可以实现灵活设计。
此外，在一些实施例中，如果密封空腔34的容积较大，可以在密封容器34内增设保温材料9，从而提升保温、防凝露等效果。
在本公开的一些实施例中，如图8和图9所示，风道组件还可以包括导风板4，导风板4设于出气口32处，且位于出气口32的远离风轮安装腔231的一侧。由此，可以通过导风板4更加有效地控制从出气口32流出的气流方向，更加有效地控制偏心涡性能，降低补气浪费，保证风量。
值得说明的是，导风板4的结构形状不限，例如可以是弧面导风板或平面导风板等，当导风板4为弧面导风板时，可以提高导流效果，当导风板4为平面导风板时，可以降低加工难度。
此外，需要说明的是，导风板4可以为固定形式，也可以为可活动形式。
例如，当导风板4为固定形式时，可以预先设计好安装角度(例如可以偏斜一定角度)，以使其可以更加有效地控制从出气口32流出的气流方向，更加有效地控制偏心涡性能，降低补气浪费，保证风量。
例如，当为可活动形式时，可选地，导风板4可以为可弹性摆动，以在靠近出气口32和远离出气口32的方向之间可摆动，即可以通过弹性部使得导风板4可弹性摆动，从而可以利用弹性自适应不同转速下对偏心涡的控制，即自动弹性摆动进行适应性控制偏心涡， 降低成本且可调节效果好。
例如，当为可活动形式时，或者可选地，导风板4可以为可驱动摆动，以在靠近出气口32和远离出气口32的方向之间可摆动，即可以通过设置驱动机构对导风板4的摆动进行驱动控制，从而可以通过控制，以在不同转速下更加有效地控制偏心涡性能，降低补气浪费，保证风量。例如，朝向远离出气口32的方向摆动时，可以降低噪音，朝向靠近出气口32的方向摆动时，可以提高抗压性，提升风量。
在本公开的一些实施例中，如图1和图2所示，进气口31设于出风段212的靠近蜗舌舌尖2b的端部，例如，进气口31与蜗舌舌尖2b之间的距离小于出风段212的长度的四分之一，结合图11和图12所示，气流在蜗舌舌尖2b处的流速较低、压力较大，从而在靠近蜗舌舌尖2b处设置进气口31，使得气流可以在压力的作用下更好地吸入进气口31，降低风量损失。例如，可选地，出风段212包括沿曲线延伸的蜗舌导风面2c和沿直线延伸的扩压面2e，进气口31设于蜗舌导风面2c与扩压面2e相接的位置附近、或者靠近蜗舌舌尖2b的位置。由此，保证气流可以更加有效地吸入进气口31。
下面，描述根据本公开实施例的空气调节设备100。
如图1所示，空气调节设备100可以包括：根据本公开任一实施例的风道组件、贯流风轮5，贯流风轮5设于风轮安装腔231。由此，可以提升空气调节设备100的通风量。
需要说明的是，根据本公开实施例的空气调节设备100的具体类型不限，可以为空调器、空气净化器、加湿器等等。此外，空调器的类型不限，例如可以为风管机、分体式空调室内机(如空调柜机、空调挂机)、一体式空调器(如窗式空调器、便携式空调器、移动空调)等等。
例如在一些实施例中，当空气调节设备100为风管机时，可以在贯流风道23的下游设置换热装置，当空气调节设备100为分体式空调室内机时，可以在贯流风道23的上游设置换热器6，这里不作赘述。
根据本公开实施例的空气调节设备100的类型确定后，空气调节设备100的其他构成以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述。例如，当空气调节设备100为空调挂机时，如图1所示，还可以包括回风格栅7、过滤网8等。如图13所示，还可以包括设于风道出口232处的导风机构110等，以用于调节送风方向、送风效果等。
