具体实施方式

下面，参照附图，描述根据本申请实施例的贯流送风组件10。
如图1和图2所示，贯流送风组件10包括：风道结构1、贯流风轮2以及止喘结构3。风道结构1包括蜗壳部11和蜗舌部12，蜗壳部11与蜗舌部12之间形成贯流风道13，贯流风道13具有风道进口131和风道出口132，贯流风轮2设于风道进口131处，且用于引发气流从风道进口131向风道出口132的方向流动。
如图1和图2所示，止喘结构3设于蜗舌部12，以减小蜗舌部12的相应位置与贯流风轮2之间的进风间隙。也就是说，蜗舌部12的设置止喘结构3的位置的进风间隙g由止喘结构3与贯流风轮2限定出，蜗舌部12的未设置止喘结构3的位置的进风间隙G由蜗舌部12与贯流风轮2限定出，其中，g＜G。由此，通过设置止喘结构3，可以减小蜗舌部12处的局部进风间隙，改善贯流风道13内的气流被倒吸回进风间隙而引发的浪涌现象，降低该现象造成的喘振异音。
结合图3，贯流风轮2包括沿轴向排列的多个中节风叶21，止喘结构3的轴向高度h小于中节风叶21的轴长H。具体而言，为了保证贯流风轮2的性能，中节风叶21的轴长需要遵守行业规范不能太长，通过限定止喘结构3的轴向高度h小于中节风叶21的轴长H，可以保证止喘结构3的长度也相对较短，避免由于止喘结构3的长度较长而难以控制形状的问题，以及由于止喘结构3的长度较长容易发生的变形问题，设计非常巧妙。
可以理解的是，由于止喘结构3用于减小局部进风间隙，其与贯流风轮2之间的距离相对较近，如果止喘结构3的形状不符合设计精度要求或者发生变形，则止喘结构3与贯流风轮2之间的距离可能非常小，容易引发贯流风轮2磕碰止喘结构3的问题，而且贯流风轮2的转动难以保证非常平稳且不变形，从而更容易引发贯流风轮2磕碰止喘结构3的问题。
根据本申请实施例的贯流送风组件10，通过限定止喘结构3的轴向高度h小于中节风 叶21的轴长H，保证能够在一定程度上改善喘振异音的前提下，有效地避免了止喘结构3因长度较长而引发的形状难以控制及易变形问题，从而降低了止喘结构3与贯流风轮2磕碰的风险，进而保证了贯流风轮2的运行可靠性，提升了贯流送风组件10的使用寿命。
需要说明的是，止喘结构3可以为一个或者多个，其中，各止喘结构3的轴向高度可以相等、也可以不相等，并且各中节风叶21的轴长可以相等、也可以不相等。因此，本文所述的“止喘结构3的轴向高度h小于中节风叶21的轴长H”指的是：任一止喘结构3的轴向高度小于任一中节风叶21的轴长。
在本申请的一些实施例中，如图3所示，止喘结构3可以设于蜗舌部12的轴向两端中的至少一端。例如，可以是蜗舌部12的轴向两端分别设有止喘结构3，又例如，还可以是蜗舌部12仅轴向一端设有止喘结构3。
可以理解的是，由于贯流风轮是通过在其内部产生偏心蜗来实现送风，但是贯流风轮的轴向两端会出现偏心蜗不连续、间断的问题，使得轴向两端失去送风稳定性，而且，当贯流风道的进风阻力较大的情况下，风道进口对应贯流风轮的两个轴向端部位置会出现明显的倒吸回流现象，浪涌现象明显，喘振异音明显。
本实施例通过在蜗舌部12的轴向两端中的至少一端设置止喘结构3，减小相应端部位置的进风间隙，从而可以改善相应位置的倒吸回流现象，有效地降低相应端部位置出现浪涌现象及喘振异音。
在本申请的一些实施例中，止喘结构3可以设于蜗舌部12的中部(即轴向中部)。具体而言，当蜗舌部12的长度较长，中部容易存在形状难以控制或形变的问题，此处容易出现偏心蜗不连续、间断的问题，失去送风稳定性，而且，当贯流风道13的进风阻力较大的情况下，风道进口131对应贯流风轮2的轴向中部位置可能会出现倒吸回流现象，引发喘振异音。本实施例通过在蜗舌部12的轴向中部设置止喘结构3，减小此处的进风间隙，从而可以改善此处的倒吸回流现象，有效地降低中部位置出现的浪涌现象及喘振异音。
另外，当贯流风轮2的轴长较长时，贯流风轮2的轴长中部在离心力的作用下可能变形更大，如果将止喘结构3设置在蜗舌部12的轴长中央位置，更容易出现与贯流风轮2磕碰的风险，从而通过控制止喘结构3的长度，可以更加有效地保证止喘结构3的形状，并降低止喘结构3的变形风险，进而有效地改善贯流风轮2与止喘结构3磕碰的问题。
在本申请的一些实施例中，止喘结构3设于蜗舌部12的轴向两端中的至少一端，同时，止喘结构3还设于蜗舌部12的中部(即轴向中部)。由此，对应贯流风轮2的相应端部以及轴向中部位置，都可以较为有效地改善倒吸回流现象，有效地降低喘振异音。
具体而言，根据本申请实施例的止喘结构3，可以设于蜗舌部12轴向上的任意位置，通过将止喘结构3设于蜗舌部12的轴向两端中的至少一端和/或设于蜗舌部12的轴向中部，可以在明显降低喘振异音的前提下，简化结构、降低成本，有效避免止喘结构3与贯流风轮2磕碰，并且保证进风阻力及进风量符合要求。
在本申请的一些实施例中，如图2所示，蜗舌部12包括舌尖段122、位于舌尖段122上游的进风段121、以及位于舌尖段122下游的出风段123，止喘结构3设于进风段121且延伸至舌尖段122，其中，止喘结构3设于舌尖段122上的部分的壁厚，沿着从进风段121到出风段123的方向逐渐减小。由此，可以有效地改善风道进口131相应位置的倒吸回流现象，以降低喘振异音，同时可以保证贯流风道13的进风要求和做功效率。
需要说明的是，止喘结构3的具体形状不限，例如，止喘结构3可以为连续结构(例如图4和图5所示)或断续结构(例如图6和图7所示)，止喘结构3的壁厚可以是等壁厚结构、止喘结构3也可以是壁厚渐变的结构，止喘结构3的表面可以为平面或曲面等等，从而满足不同的设计需求，这里不作赘述。
在本申请的一些实施例中，如图2所示，止喘结构3与贯流风轮2之间的间隙g为0.04D-0.05D，其中，D为贯流风轮2的直径，例如，g可以为0.04D、0.042D、0.044D、0.046D、0.048D、0.05D等等。由此，可以较为有效地改善风道进口131相应位置的倒吸回流现象，以降低喘振异音，同时可以保证进风阻力及进风量符合要求。
在本申请的一些实施例中，如图2所示，止喘结构3与贯流风轮2之间的间隙g为3.5mm-4.5mm，例如，g可以为3.5mm、3.7mm、3.9mm、4.0mm、4.1mm、4.3mm、4.5mm等等。由此，可以较为有效地改善风道进口131相应位置的倒吸回流现象，以降低喘振异音，同时可以保证进风阻力及进风量符合要求。
在本申请的一些实施例中，如图3所示，止喘结构3的轴向高度h满足：0.25H≤h≤0.875H，其中，H为多个中节风叶21中轴长最短的中节风叶21的轴长，例如，h可以为0.25H、0.3H、0.35H、0.4H、0.45H、0.5H、0.55H、0.6H、0.65H、0.7H、0.75H、0.8H、0.875H等等。由此，可以较为有效地改善风道进口131相应位置的倒吸回流现象，以降低喘振异音，同时可以有效地避免止喘结构3与贯流风轮2发生磕碰的问题。
在本申请的一些实施例中，如图3所示，止喘结构3的轴向高度h为40mm-60mm，例如，h可以为40mm、45mm、50mm、55mm、60mm，等等。由此，可以较为有效地改善风道进口131相应位置的倒吸回流现象，以降低喘振异音，同时可以有效地避免止喘结构3与贯流风轮2发生磕碰的问题。
需要说明的是，止喘结构3与蜗舌部12的连接方式不限。例如在本申请的一些实施例中，止喘结构3与蜗舌部12为分体件且固定相连，从而可以分别单独加工止喘结构3与蜗舌部12，无需特殊重新设计蜗舌部12，降低蜗舌部12的开发成本，并且可以选用合适的材料加工止喘结构3，保证止喘结构3的功效可靠。又例如在本申请的一些实施例中，止喘结构3与蜗舌部12为一体件，即两者为不可分离的整体结构，从而省去了装配过程，而且保证止喘结构3与蜗舌部12的连接可靠，保证止喘结构3可以在固定位置发挥可靠的止喘效果。再例如在本申请的一些实施例中，止喘结构3与蜗舌部12滑动相连，以使止喘结构3在蜗舌部12的轴向上的位置可调节，从而可以根据实际情况调整止喘结构3的位置，有效地降低喘振异音。
下面，描述根据本申请实施例的空调器1000。
如图8-图10所示，空调器1000可以包括：壳体部件100、换热部件200和送风部件300。其中，送风部件300包括根据本申请任一实施例的贯流送风组件10，壳体部件100上具有进风区域101和出风区域102，换热部件200和送风部件300均设于壳体部件100内。这样，当送风部件300工作时，可以引发壳体部件100外的空气进入壳体部件100内，空气经与换热部件200换热后改变温度，之后从出风区域102送出。由此，由于送风部件300包括根据本申请任一实施例的贯流送风组件10，从而可以有效地改善喘振异音问题，且能够较为有效地保证送风部件300的工作可靠性。
在本申请的一些实施例中，如图8和图9所示，送风部件300为双贯流送风装置且包括第一送风单元301和第二送风单元302，换热部件200包括设于送风部件300上游的换热器201，换热器201包括中央部2011、第一侧部2012和第二侧部2013，第一侧部2012设于第一送风单元301的远离第二送风单元302的一侧，第二侧部2013设于第二送风单元302的远离第一送风单元301的一侧，中央部2011连接在第一侧部2012与第二侧部2013之间且位于第一送风单元301和第二送风单元302的同侧，第一送风单元301与第二送风单元302之间设有朝向中央部2011的方向延伸的分流结构件400，例如分流结构可以包括两个隔板401，分别朝向两个送风单元引流。
由此，空气从进风区域101进入壳体部件100内之后，可以先经过换热器201，穿过换热器201的中央部2011的气流可以被分流结构件400分流，以分别流向第一送风单元301和第二送风单元302，经过第一侧部2012的气流流向第一送风单元301，经过第二侧部2013的气流流向第二送风单元302。
可以理解的是，对于双贯流送风装置来说，两个送风单元分别包括贯流风机和贯流风道 13。贯流风机的轴向为换热器201每个部分的长度方向，换热器201每个部分的宽度为垂直于自身长度方向和厚度方向的延伸尺寸。
其中，第一侧部2012的宽度W1小于第二侧部2013的宽度W2，至少第一送风单元301为根据本申请任一实施例的贯流送风组件10，也就是说，可以仅第一送风单元301为贯流送风组件10，或者也可以是第一送风单元301和第二送风单元302均为根据本申请任一实施例的贯流送风组件10。
具体而言，由于第一侧部2012的宽度W1小于第二侧部2013的宽度W2，因此，对应第一侧部2012设置的第一送风单元301的进风阻力会高于第二送风单元302的进风阻力，第一送风单元301的喘振异音相对严重，而且，受风压影响，第二送风单元302还容易通过分流结构件400与中央部2011之间的间隙从第二送风单元302的进风侧抢风，从而导致第一送风单元301的喘振异音更为严重，通过将第一送风单元301设置为根据本申请任一实施例的贯流送风组件10，包括止喘结构3，从而可以有效地改善第一送风单元301的喘振异音问题。此外，当第二送风单元302也为根据本申请任一实施例的贯流送风组件10，包括止喘结构3时，还可以有效地避免第二送风单元302的喘振异音问题。
例如在一些可选示例中，结合图10，第一送风单元301为贯流送风组件10且第一送风单元301的蜗舌部12的轴向两端分别设有设有止喘结构3，第二送风单元302也为贯流送风组件10且第二送风单元302的蜗舌部12的轴向两端分别设有设有止喘结构3。由此，可以更加充分地改善第一送风单元301和第二送风单元302的喘振异音问题。
可选地，各止喘结构3(即上述示例中四个止喘结构3)的规格一致可通配安装。也就是说，四个止喘结构3是一模一样的，从而只需开发生产一种止喘结构3即可，向蜗壳部11安装无需进行区分选择，从而有利于降低生产成本，且可以提升生产效率。当然，本申请不限于此，例如还可以根据各个位置的喘振异音情况，针对性设置各止喘结构3的尺寸，这里不作赘述。
在本申请的一些实施例中，如图8所示，进风区域101可以包括中央进风区域1011和位于中央进风区域1011两侧的第一侧进风区域1012和第二侧进风区域1013，第一侧进风区域1012对应第一侧部2012设置，第二侧进风区域1013对应第二侧部2013设置，出风区域102可以包括分别对应第一送风单元301设置的第一出风区域1021和对应第二送风单元302设置的第二出风区域1022。
如上文所述由于第一侧部2012的宽度W1小于第二侧部2013的宽度W2，因此，对应第一侧部2012设置的第一送风单元301的进风阻力会高于第二送风单元302的进风阻力。 一般情况下，由于第一侧部2012的宽度W1相对第二侧部2013的宽度W2较小，通常会在对应第一侧部2012的第一侧进风区域1012的边缘位置设置滤网扣手103，从而导致第一侧进风区域1012的宽度a小于第二侧进风区域1013的宽度b，这样则会进一步增大第一送风单元301的进风阻力。
因此，在本申请的实施例中，将第一侧进风区域1012的宽度a与第二侧进风区域1013的宽度b设计为满足：b-a≤0.2b。也就是说，第一侧进风区域1012的宽度a可以小于第二侧进风区域1013的宽度，但是差值不能小于0.2b，从而适当降低第一送风单元301的进风阻力，进一步改善第一送风单元301的喘振异音情况。可选地，可以设置b-a≥12mm，从而一方面可以改善第一送风单元301的喘振异音情况，另一方面保证滤网扣手103的易加工性。另外，可以理解的是，通过设置第一侧部2012的宽度W1小于第二侧部2013的宽度W2，可以利用第一侧部2012较短的位置设置冷媒管路等，这里不作赘述。
值得说明的是，根据本申请实施例的换热部件200、送风部件300、进风区域101均整体为对称结构，即换热部件200忽略第一侧部2012和第二侧部2013的宽度差异整体为轴对称结构，送风部件300忽略是否有止喘结构3的细微差别整体也为轴对称结构，进风区域101忽略第一侧进风区域1012和第二侧进风区域1013的宽度差异整体为轴对称结构，且换热部件200、送风部件300、进风区域101三者的轴对称平面相同。
此外，在本申请的一些实施例中，如图8和图9所示，换热部件200还可以包括设于两个隔板401两侧的电辅热202等，这里不作赘述。
相关技术中的双贯流柜机，主风道由左右两侧的贯流风轮组合而成，主风道出口主要包括贯流风轮、前蜗舌、蜗壳底盘、转筒、转筒导风叶、铁丝网等组成，风轮电机通电带动贯流风轮旋转，左右两侧的贯流风轮高速转动，将进气格栅外的空气经过蒸发器进入到左右主风道，并经过贯流风轮的做工从出风口吹出，从而达到快速调节室内温度，改善环境的目的。在进行性能测试时，在柜机的进气口处蒙两层纱布来模拟进气滤网和蒸发器常年积灰工况，在制冷挂水测试条件下，两侧风道会因为进风阻力变大，使得贯流风扇的两端的端部的出风失去稳定性，会出现喘振异音问题。
分析具体原因，由于贯流风轮是通过在其内部产生偏心蜗来实现送风，但是贯流风轮在风道的两端会出现偏心蜗不连续，出现端部间断的问题，使得两侧端部失去送风的稳定性，特别是在进风口出现脏堵情况下，风道的两个端部前蜗舌位置处会出现明显的回流现象，从而出现了浪涌或者喘振异音的问题。
并且，左右风道通常采用对称设计，但是由于蒸发器左右长度不是对称设计的，右侧蒸 发器进气端弧长125.5mm，左侧蒸发器进气端弧长161.8mm，两侧相差36.3mm，在蒸发器挂水后，由于在进风格栅处蒙两层纱布，右侧风道在制冷模式下会出现出风不连续的浪涌现象，出现风道喘振异音。
为了解决上述技术问题，在本申请一个具体实施例的空调器1000中，如图8-图10所示，可以将右侧进风区域101的宽度增加c(例如10mm)以增大右侧的进气面积，左右两侧的蜗舌部12的上端部和下端部分别设置止喘结构3，以使进气间隙减小至4mm左右，其余位置的进气间隙为5.5mm，在止喘结构3相当于将进气间隙减小1.5mm，因此止喘结构3的厚度t为1.5mm。并且止喘结构3的轴向高度为50mm，贯流风轮2的中节风叶21的轴承为61.6mm。由此，通过设置止喘结构3，并增大右侧进风区域101的宽度，能够有效地解决双贯流柜机风道在模拟蒸发器及进气滤网脏堵情况下出风不连续引发的喘振异音问题。
简言之，根据本申请一些实施例的空调器1000，一方面通过增加宽度相对较小的第一侧进风区域1012的进气面积来增加进气量，另一方面通过将各蜗舌部12的轴向两端的进风间隙调小，可以有效地减小风道中的风通过对应位置的进风间隙倒吸回进风侧的问题，有效地降低了风道两端出现浪涌现象引发的喘振异音问题。
需要说明的是，根据本申请实施例的贯流送风组件10，所应用的空调器1000的类型不限于双贯流柜机，例如还可以用于单贯流柜机、挂机、窗机等上，例如，在单贯流空调的蜗舌部12的两个端部中的至少一个上设置止喘结构3，改善相应端部出现的喘振异音问题。另外，对于一些轴长较长的贯流风轮2来说，也可能在中部出现喘振异音问题，因此也可以在蜗舌部12的轴长中部设置止喘结构3，降低喘振异音。
