【具体实施方式】
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请的实施例，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
为解决现有技术中制冷设备其风道的风流分布不均匀的技术问题，本申请的一实施例提供一种风道组件。该风道组件包括风道，风道包括进风段和出风段；出风段设有分流筋，分流筋将出风段分成第一子风道和第二子风道，分流筋的中心线与风道的中心线重合；进风段设有第一导风筋，第一导风筋的中心线偏离风道的中心线。该风道组件还包括第一进风口和第二进风口，均与进风段连通，第一导风筋在参考平面上的正投影与第一进风口在参考平面上的正投影存在交叠，参考平面垂直于风道的中心线，第一进风口设置为能够单独开启或与第二进风口同时开启。以下进行详细阐述。
请参阅图1，图1是本申请风道组件第一实施例的结构示意图。
在一实施例中，风道组件10应用于制冷设备，例如应用于诸如冰箱等制冷设备，风道组件10具体用于将冷气输送至制冷设备用于存放物品的间室，实现间室内物品的冷藏或冷冻保藏。
风道组件10包括风道11。风道11包括进风段111和出风段112。出风段112设有分流筋12，分流筋12将出风段112分成第一子风道1121和第二子风道1122，分流筋12的中心线(如图1中虚线A所示，下同)与风道11的中心线(如图1中虚线B所示，下同)重合。由于本实施例风道组件10用于向其所应用的制冷设备的间室的不同部分提供冷气，因此需要风流在风道11分布均匀，有利于保证间室内不同部分的冷气量分布均匀，进而保证间室内不同部分的温度分布均匀，有利于物品的保藏以及改善用户的使用体验。其中，中心线定义为各元件在各自宽度方向(沿着如图1所示的水平方向)上的中垂线。
风道组件10还包括第一进风口13和第二进风口14。第一进风口13和第二进风口14分别与风道11的进风段111连通。其中，第一进风口13设置为能够单独开启或与第二进风口14同时开启，以实现制冷设备的间室的冷藏和冷冻转换功能。
具体地，当第一进风口13单独开启时，冷气仅通过第一进风口13输出至风道11，进而输送至制冷设备的间室，此时输送至制冷设备的间室的冷气量较少，间室具备冷藏功能。而当第一进风口13与第二进风口14同时开启时，冷气同时通过第一进风口13和第二进风口14输出至风道11，进而输送至制冷设备的间室，此时输送至制冷设备的间室的冷气量较多，间室具备冷冻功能，即实现制冷设备的间室的冷藏和冷冻转换功能。
可选地，第一进风口13和第二进风口14分别设置有用于实现各自开启和关闭的结构，例如可以是可调节的挡板等结构。通过控制第一进风口13和第二进风口14各自对应的该结构动作，以分别实现第一进风口13和第二进风口14的开启和关闭。
在本实施例中，风道11的进风段111设有第一导风筋15，第一导风筋15的中心线(如图1中虚线C所示，下同)偏离风道11的中心线。并且，第一导风筋15在参考平面(如图1中平面α所示，下同)上的正投影与第一进风口13在参考平面上的正投影存在交叠，其中参考平面为垂直于风道11的中心线的平面。
如此一来，当第一进风口13单独开启时，第一进风口13输出的风流在到达第一导风筋15后，一部分风流输送至第一子风道1121，另一部分风流输送至第二子风道1122，使得风道11的风流分布均匀，即能够改善风流分布的均匀性，使得制冷设备的间室内部的温度分布均匀，进而有利于物品的保藏以及改善用户的使用体验。而当第一进风口13与第二进风口14同时开启时，自第一进风口13和第二进风口14输出的风流自然而然地均匀流向第一子风道1121和第二子风道1122，即此时风道11内的风流同样分布均匀。
需要说明的是，风道11设有进风口113，输入至风道11的风流通过进风口113进入制冷设备的间室内部，以对间室内存放的物品进行低温保藏。
请继续参阅图1。在一实施例中，第一导风筋15的中心线平行于风道11的中心线，并且第一导风筋15的中心线位于风道11的中心线的一侧，使得第一导风筋15的中心线偏离风道11的中心线。当第一进 风口13单独开启时，第一导风筋15能够对自第一进风口13输出的风流起到分流作用，即使得一部分风流输送至第一子风道1121，另一部分风流输送至第二子风道1122，进而使得风道11的风流分布均匀，能够改善风流分布的均匀性。
进风段111包括相对的第一侧边缘1111和第二侧边缘1112，第一侧边缘1111位于第一进风口13远离第二进风口14的一侧，第二侧边缘1112位于第二进风口14远离第一进风口13的一侧。
第一导风筋15的中心线和第一侧边缘1111在预定方向(如图1中虚线β所示，下同)上的距离与第一导风筋15的中心线和第二侧边缘1112在预定方向上的距离的比例范围为1:2至3:4。其中，预定方向经过第一导风筋15的中心(如图1中点O1所示，下同)且垂直于风道11的中心线。
请一并参阅图2，第一导风筋15的中心O1定义为第一导风筋15在其长度方向(沿着如图1所示的竖直方向)上的中垂线C与在其宽度方向(沿着如图1所示的水平方向)上的中垂线(即第一导风筋15的中心线D)的交点。
请继续参阅图1，第一子风道1121靠近第一进风口13设置，第二子风道1122靠近第二进风口14设置。第一导风筋15和分流筋12之间具有一定的间隙。第一导风筋15和第一侧边缘1111在预定方向上的距离与第一导风筋15和第二侧边缘1112在预定方向上的距离的比例满足上述比例范围，使得第一导风筋15靠近风道11的中心线，以尽量避免当第一进风口13单独开启时经第一导风筋15分流且流向第二子风道1122的风流自第一导风筋15和分流筋12之间的间隙回流至第一子风道1121，进一步保证风流分布的均匀性。
并且，进一步地，在一些具体的实施例中，第一导风筋15在预定方向上的长度与进风段111在预定方向上的长度的比例范围为1:7至1:5。如此一来，使得第一导风筋15具有足够的宽度，进而使得到达第一导风筋15的风流尽可能地被第一导风筋15等量分流，尽可能保证流向第一子风道1121和第二子风道1122的风流的风量相等，进一步保证风流分布的均匀性。
在一具体的实施例中，第一进风口13的出风面积与第二进风口14的出风面积差异设计，意味着第一进风口13的风量不同于第二进风口14的风量，但第一进风口13和第二进风口14的出风面积总和是固定不变的，即当第一进风口13与第二进风口14同时开启时输入风道11的风流风量是固定不变的。
具体地，第一进风口13的出风面积可以小于第二进风口14的出风面积，意味着当第一进风口13单独开启时输入风道11的风流风量较小，输送至制冷设备的间室的冷气量较少，此时间室的温度较高，第一进风口13的出风面积与第二进风口14的出风面积的比例优选为1:2；第一进风口13的出风面积可以大于第二进风口14的出风面积，意味着当第一进风口13单独开启时输入风道11的风流风量较大，输送至制冷设备的间室的冷气量较多，此时间室的温度较低，第一进风口13的出风面积与第二进风口14的出风面积的比例优选为2:1；当第一进风口13与第二进风口14同时开启时，输入风道11的风流风量最大化，使得输送至制冷设备的间室的冷气量最大化，此时间室的温度最低。
可以看出，通过第一进风口13的出风面积与第二进风口14的出风面积的差异设计，当第一进风口13具有不同大小的出风口时，会使得第一进风口13单独开启时间室具有不同的温度，即实现间室所处温区的多样化调节。举例而言，当第一进风口13的出风面积小于第二进风口14的出风面积时，第一进风口13单独开启，此时间室处于冷藏温区；而当第一进风口13的出风面积大于第二进风口14的出风面积时，第一进风口13单独开启，此时间室处于变温区。
需要说明的是，由于第一进风口13的最小截面决定了第一进风口13输出风流的风量，因此第一进风口13的出风面积定义为第一进风口13的最小截面的面积，该最小截面平行于上述的参考平面。同理，第二进风口14的出风面积定义为第二进风口14的最小截面的面积，该最小截面平行于上述的参考平面。
由于第一进风口13的出风面积与第二进风口14的出风面积差异设计，导致其出风量也会有差异，因此要想送入间室内的风流分布的均匀性，则对应的第一导风筋15的特征要进一步优化。进一步地，请继续参阅图1。在一实施例中，第一进风口13的出风面积小于第二进风口14的出风面积。第一导风筋15的中心线和第一侧边缘1111在上述预定方向上的距离L1、第一导风筋15的中心线和第二侧边缘1112在预定方向上的距离L2具有如是关系：L1:L2＝1:2。第一导风筋15在预定方向上的长度L3、进风段111在预定方向上的长度L4具有如是关系：L3:L4＝1:5。
如此一来，第一导风筋15靠近风道11的中心线，以尽量避免当第一进风口13单独开启时经第一导风筋15分流且流向第二子风道1122的风流自第一导风筋15和分流筋12之间的间隙回流至第一子风道1121，进一步保证风流分布的均匀性。并且，第一导风筋15具有足够的宽度，使得当第一进风口13单独开启时到达第一导风筋15的风流尽可能地被第一导风筋15等量分流，尽可能保证流向第一子风道1121和第二子风道1122的风流的风量相等，进一步保证风流分布的均匀性。
进一步地，第一导风筋15朝向第一进风口13的一侧具有第一导风面151，第一导风面151朝向第一进风口13倾斜设置，用于引导风流流向第二子风道1122，有利于改善第一导风筋15引导风流流向的效果，进一步保证风流分布的均匀性。
可选地，第一导风面151与风道11的中心线的夹角范围为25°至30°，优选为25°等。如图1所示，第一导风面151与风道11的中心线的夹角为θ1，其中θ1的取值范围为25°至30°，优选为25°等。如此一来，能够最大限度地改善第一导风筋15引导风流流向的效果，最大限度地保证风流分布的均匀性。
进一步地，由于制冷设备通常由蜗流离心风机提供冷气，因此自第一进风口13和第二进风口14输出的风流存在一定的偏向。有鉴于此，风道组件10还包括若干第三导风筋16，该若干第三导风筋16按照预设排布方式设置于进风段111，该若干第三导风筋16相对第一导风筋15靠近第一进风口13和第二进风口14。第三导风筋16至少其朝向第一进风口13和第二进风口14的端部的横截面面积沿靠近第一进风口13和第二进风口14的方向逐渐减小，能够引导自第一进风口13和第二进风口14输入风道11的风流沿风道11的中心线流动，缓解风流流向紊乱的情况，进一步有利于保证风流分布的均匀性。其中，第三导风筋16的横截面垂直于风道11的中心线。
上述若干第三导风筋16按照预设排布方式设置于进风段111具体可以是该若干第三导风筋16沿上述的预定方向依次间隔排布。举例而言，该若干第三导风筋16的数量为两个，具体是导风筋161和导风筋162，其中导风筋161靠近第一侧边缘1111，导风筋162靠近第二侧边缘1112。
进风段111包括聚拢段1113和扩张段1114，聚拢段1113相对扩张段1114靠近第一进风口13和第二进风口14，即自第一进风口13和第二进风口14输出的风流先经过聚拢段1113，而后经过扩张段1114。其中，扩张段1114的风道宽度大于聚拢段1113的风道宽度，聚拢段1113优选为其在风道11的中心线上的各个位置的风道宽度相等，聚拢段1113能够对自第一进风口13和第二进风口14输出的风流起到一定的聚拢作用，使得风流尽可能沿风道11的中心线流动，进一步有利于保证风流分布的均匀性。
对于上述若干第三导风筋16包括导风筋161和导风筋162的举例，导风筋161的中心线和第一侧边缘1111在聚拢段1113中的部分之间的距离L5、导风筋162的中心线和第二侧边缘1112在聚拢段1113中的部分之间的距离L6、聚拢段1113的风道宽度L7具有如是关系：L5＝L6、L5:L6:L7＝1:1:5。如此一来，自第一进风口13输出的风流能够接受导风筋161的引导，而自第二进风口14输出的风流能够接受导风筋162的引导，使得自第一进风口13和第二进风口14输出的风流沿风道11的中心线流动，能够缓解风流流向紊乱的情况，进一步有利于保证风流分布的均匀性。
可选地，导风筋161的中心线与第一导风筋15的中心线重合。
当然，本实施例所阐述若干第三导风筋16的预设排布方式并不局限于上文所述的沿预定方向依次间隔排布，并且本申请的其它实施例也可以应用本实施例所阐述的第三导风筋16，在此不做限定。
图3展示了本实施例中当第一进风口13单独开启时风道11内的风流流动情况，图4展示了本实施例中当第一进风口13和第二进风口14同时开启时风道11内的风流流动情况。
举例而言，常见的制冷设备，如冰箱等，通常具有上下两个间室并由同一套制冷装置提供冷气。在本实施例的风道组件10应用于具有上下两个间室的制冷设备的情况下，本实施例的风道组件10用于向其中一个间室输送冷气。具体地，本实施例中第一进风口13的出风面积小于第二进风口14的出风面积，当第一进风口13单独开启时，风道组件10对应的间室与另一间室的风量之比为1:3，有利于降低制冷设备的能耗；而当第一进风口13和第二进风口14同时开启时，风道组件10对应的间室与另一间室的风量之比为2:3。
请参阅图5，图5是本申请风道组件第二实施例的结构示意图。
在一实施例中，本实施例与上述实施例的不同之处在于：第一进风口13的出风面积大于第二进风口 14的出风面积。由于本实施例中第一进风口13的出风面积大于上述实施例的第一进风口13的出风面积，因此本实施例的第一导风筋15相对上述实施例而言更加靠近风道11的中心线，使得到达第一导风筋15的风流能够被均匀分流，以保证风流分布的均匀性。
具体地，本实施例中第一导风筋15的中心线和第一侧边缘1111在上述预定方向上的距离W1、第一导风筋15的中心线和第二侧边缘1112在预定方向上的距离W2具有如是关系：W1:W2＝3:4。由于风道11的进风段111的风道宽度不变，可见本实施例第一导风筋15和第一侧边缘1111在上述预定方向上的距离与第一导风筋15和第二侧边缘1112在预定方向上的距离的比例大于上述实施例所示比例，即本实施例的第一导风筋15更加靠近风道11的中心线。
并且，第一导风筋15在预定方向上的长度W3、进风段111在预定方向上的长度W4具有如是关系：W3:W4＝1:7，使得第一导风筋15具有足够的宽度，进而使得当第一进风口13单独开启时到达第一导风筋15的风流尽可能地被第一导风筋15等量分流，尽可能保证流向第一子风道1121和第二子风道1122的风流的风量相等，进一步保证风流分布的均匀性。
在本实施例中，第一导风筋15上的第一导风面151与风道11的中心线的夹角优选为30°等。如图5所示，θ1优选为30°等。如此一来，能够最大限度地改善第一导风筋15引导风流流向的效果，最大限度地保证风流分布的均匀性。
进一步地，由于本实施例中第一进风口13的出风面积大于第二进风口14的出风面积，当第一进风口13和第二进风口14同时开启时，风道11中靠近第一进风口13的部分风压较大，而风道11中靠近第二进风口14的部分风压较小，导致自第二进风口14输入的风流较难自然流向第一子风道1121，致使自第二进风口14输入的风流大部分流向第二子风道1122而引发风流分布不均的问题。
有鉴于此，风道组件10还包括第二导风筋17。第二导风筋17的中心线偏离风道11的中心线，并且第二导风筋17在参考平面上的正投影与第二进风口14在参考平面上的正投影存在交叠。优选地，第二导风筋17的中心线平行于风道11的中心线，第二导风筋17的中心线位于风道11的中心线的一侧，使得第二导风筋17的中心线偏离风道11的中心线。如此一来，当第二进风口14开启时，第二进风口14输出的风流在到达第二导风筋17后，一部分风流输送至第一子风道1121，另一部分风流输送至第二子风道1122，使得风道11内的风流分布均匀，以进一步保证风流分布的均匀性。
第一导风筋15的中心线和第一侧边缘1111在预定方向上的距离W1、第二导风筋17的中心线和第二侧边缘1112在预定方向上的距离W5具有如是关系：W1:W5＝3:2，以进一步保证第二进风口14输出的风流在到达第二导风筋17后，一部分风流能够在第二导风筋17的引导下流向第一子风道1121，进而保证风流分布的均匀性。
需要说明的是，上述第一进风口13的出风面积小于第二进风口14的出风面积的实施例中，风道组件10未设置第二导风筋17，其原因在于：第一进风口13的出风面积小于第二进风口14的出风面积，当第一进风口13和第二进风口14同时开启时，风道11中靠近第一进风口13的部分风压较小，而风道11中靠近第二进风口14的部分风压较大，自第二进风口14输入的风流会自然流向第一子风道1121而使得风流分布均匀。
更进一步地，第二导风筋17朝向第二进风口14的一侧具有第二导风面171，第二导风面171朝向第二进风口14倾斜设置，用于引导风流流向第一子风道1121，有利于改善第二导风筋17引导风流流向的效果，进一步保证风流分布的均匀性。
可选地，第二导风面171与风道11的中心线的夹角范围为20°至25°，优选为20°等。如图5所示，第二导风面171与风道11的中心线的夹角为θ2，其中θ2的取值范围为20°至25°，优选为20°等。如此一来，能够最大限度地改善第二导风筋17引导风流流向的效果，最大限度地保证风流分布的均匀性。
图6展示了本实施例中当第一进风口13单独开启时风道11内的风流流动情况，图7展示了本实施例中当第一进风口13和第二进风口14同时开启时风道11内的风流流动情况。
对于上述制冷设备具有上下两个间室并由同一套制冷装置提供冷气的情况，本实施例中第一进风口13的出风面积大于第二进风口14的出风面积，当第一进风口13单独开启时，风道组件10对应的间室与另一间室的风量之比为1:2，风道组件10对应的间室的风量较大，有利于快速降温；而当第一进风口13和 第二进风口14同时开启时，风道组件10对应的间室与另一间室的风量之比为2:3。
请参阅图8，图8是本申请风道组件第三实施例的结构示意图。
在一实施例中，本实施例与上述实施例的不同之处在于：第一导风筋15转动设置于进风段111。进一步地，可以由埋设于风道11的电机带动第一导风筋15转动。第一导风筋15可转动至朝向第一进风口13倾斜设置，使得第一导风筋15的中心线偏离风道11的中心线，并且第一导风筋15在参考平面上的正投影与第一进风口13在参考平面上的正投影存在交叠。需要说明的是，第一导风筋15转动设置于进风段111表现为第一导风筋15能够绕一转动中心(如图8中点O2所示，下同)自转，该转动中心与第一导风筋15的中心线重合。进一步地，该转动中心与第一导风筋15的中心重合。
如此一来，当第一进风口13单独开启时，第一导风筋15能够对自第一进风口13输出的风流起到分流作用，即使得一部分风流输送至第一子风道1121，另一部分风流输送至第二子风道1122，进而使得风道11的风流分布均匀，能够改善风流分布的均匀性。
在本实施例中，第一导风筋15的中心线偏离风道11的中心线表现为第一导风筋15的中心线与风道11的中心线成角度设置，并且本实施例中第一进风口13的出风面积大于第二进风口14的出风面积，第一导风筋15可转动至第一导风筋15的中心线与风道11的中心线的夹角范围优选为25°至35°。如图8所示，第一导风筋15的中心线与风道11的中心线的夹角为θ3，图8中角θ3为30°。
请参阅图9，第一导风筋15的转动中心与风道11的中心线重合。当第一进风口13和第二进风口14同时开启时，为避免倾斜设置的第一导风筋15影响风流的分布，第一导风筋15可转动至第一导风筋15的中心线与风道11的中心线重合，使得自第一进风口13和第二进风口14输入风道11的风流均匀流向第一子风道1121和第二子风道1122，进而能够改善风流的分布均匀性。
图10展示了本实施例中当第一进风口13单独开启时风道11内的风流流动情况，图11展示了本实施例中当第一进风口13和第二进风口14同时开启时风道11内的风流流动情况。
请参阅图12，图12是本申请风道组件第四实施例的结构示意图。
在替代实施例中，第一进风口13的出风面积小于第二进风口14的出风面积，即相对于上述实施例而言第一进风口13的出风面积减小，意味着第一导风筋15需要转动更大角度，才能使得第一导风筋15当第一进风口13单独开启时能够对自第一进风口13输出的风流起到分流作用，保证风流分布的均匀性。具体地，第一导风筋15可转动至第一导风筋15的中心线与风道11的中心线的夹角范围优选为40°至50°。如图12所示，角θ3为45°。
综上所述，本申请所提供的风道组件，其包括第一进风口和第二进风口，第一进风口设置为能够单独开启或与第二进风口同时开启，以实现制冷设备的间室的冷藏和冷冻转换功能。
并且，该风道组件的进风段设有第一导风筋，第一导风筋的中心线偏离风道的中心线且第一导风筋在参考平面上的正投影与第一进风口在参考平面上的正投影存在交叠。如此一来，当第一进风口单独开启时，第一进风口输出的风流在到达第一导风筋后，一部分风流输送至第一子风道，另一部分风流输送至第二子风道，使得风道的风流分布均匀，即能够改善风流分布的均匀性，使得制冷设备的间室内部的温度分布均匀，进而有利于物品的保藏以及改善用户的使用体验。

需要说明的是，风道组件10已在上述实施例中详细阐述，在此就不再赘述。内腔体20的内部储物空间即为上述实施例所阐述的用于存放物品的间室。制冷装置30可以包括蜗壳以及设于蜗壳中的离心风机，其属于本领域技术人员的理解范畴，在此就不再赘述。
