在本申请的描述中，需要理解的是，术语“第一”、“第二”等仅用于描述目的，而不能理解为指示或暗示相对重要性。此外，在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。
实施例1
如图1所示，一种出风风道结构，包括相对设置的第一风道壁110和第二风道壁210，在第一风道壁110和第二风道壁210之间形成出风通道3，第一风道壁110沿气流方向包括相连的多个凹曲面，多个凹曲面的曲率半径沿气流方向依次减小。
在出风通道3深度比较大的情况下，第一风道壁110沿气流方向包括相连的多个凹曲面，这样可以灵活处理出风通道3，以便达到预期最大出风风量效果，而在本实施例中， 优选为，多个凹曲面包括第一凹曲面111和第二凹曲面112，第一凹曲面111的曲率半径为R1，第二凹曲面112的曲率半径为R2，
R1与R2在连接处相切，以形成圆滑曲面，避免对风进行阻挡,优选地，R1与R2满足关系：R1＝k1*R2，1.5≤k1≤2，k1优选为2，从而达到更好的出风效果，150mm≤R1≤250mm，50mm≤R2≤150mm，R1圆心角范围优选为25°-45°，R2圆心角范围优选为25°-75°。
第二风道壁210包括靠近出风通道3的出风口310设置的第三凹曲面211，第三凹曲面211的曲率半径为R，优选地，R与R2满足关系：R＝k2*R2，3≤k2≤4，k2优选为4，150mm≤R≤550mm，R圆心角范围为18°-66°，第三凹曲面211不仅可以减小对流经出风口出来的风的阻挡，减小风阻，增大风量，而且更加美观，通过实验测试得出在不出现其他异常，例如出风口凝露的情况下，第三凹曲面211尺寸达到最大，风量将达到最大值的效果，验证数据约为：单个出风口尺寸每减小5mm，单个出风口的风量减小7m3/h，曲率半径为150mm时，圆心角为66°，曲率半径为550mm时，圆心角为18°，在实际运用过程中，该数据根据天井式空调内机的大小会有所不同。
当风从出风通道3的进风口流入时，流入的部分风在第二凹曲面112的阻挡下流向第三凹曲面211,流向第三凹曲面211的风能对第三凹曲面211进行冷却，以免出现凝露。
实施例2
如图2、图3所示，一种出风面板，包括面板体1和设置在面板体1角部的角盖板2，角盖板2与面板体1构成所述出风风道结构，面板体1的部分侧面构成第一风道壁110，角盖板2的部分侧面构成第二风道壁210，角盖板2与面板体1之间形成出风面板的角部出风口。
角盖板2靠近出风面板的中心的一端21相较于面板体1的远离出风面板的中心的一端11更加靠近出风面板的中心设置，或者在由出风面板的中心向出风面板的外边缘的方向上，角盖板2靠近出风面板的中心的一端21与面板体1的远离出风面板的中心的一端11相邻接，如此，能够保证气流均要经过面板体1的导流作用再从角部出风口流出，从而有效避免凝露问题(因此当角盖板2靠近出风面板的中心的一端21与面板体1的远离出风面板的中心的一端11不邻接，而是之间具有缝隙时，有一部分气流会直接由缝隙流出，缝隙越大，则导流作用越小，气流越少经过角盖板2，越容易出现凝露)。
实施例3
如图4和图5所示，在实施例1的基础上为了进一步扩大出风通道3出风口的尺寸，角盖板2与面板体1之间设置有导流结构4。
其中，在由出风面板的中心向出风面板的外边缘的方向上，导流结构4与面板体1和/或角盖板2部分重叠，或者，
在由出风面板的中心向出风面板的外边缘的方向上，导流结构4靠近出风面板的中心的一端41与面板体1的远离出风面板的中心的一端11相邻接，和/或，导流结构4远离出风面板的中心的一端42与角盖板2的靠近出风面板的中心的一端21相邻接，采用上述设计方式，能够避免因出现漏风情况，而导致达不到效果。
优选地，在由出风面板的中心向出风面板的外边缘的方向上，导流结构4与面板体1相重叠的部分的尺寸为小于或等于2mm；和/或，
在由出风面板的中心向出风面板的外边缘的方向上，导流结构4与角盖板2相重叠的部分的尺寸为小于或等于2mm，采用上述设计方式，能够避免因面积重合过大，而导致风阻过大，风量过小的问题。
导流结构4的具体结构如下：
导流结构4包括一个导流板或沿气流方向排布的多个导流板。
如图5、图7所示，当导流板的数量为一块时，导流板的两端均通过连接部与角盖板2连接，连接部例如可以为连接板，导流板的背风侧的侧面上设置有凸起结构410，出风面板为天井式空调内机的出风面板，导流板与水平面的夹角大于或等于0°且小于90°，凸起结构410包括多个条状凸起。在由出风面板的中心向出风面板的外边缘的方向上，多个条状凸起410相互间隔设置，通过凸起结构410的作用能防止导流板的背风侧的侧面因风速较低而产生凝露现象。
如图6所示，当导流板的数量为两块及以上时，各导流板沿风向方向的投影连续，各导流板的两端均通过连接部与角盖板2连接，各导流板与水平面的夹角大于或等于0°且小于90°。
所有导流板在布置时其间距需满足如下关系要求：h＝H/(n+1)，其中，h为相邻两块导流板之间的间距，H为出风口的尺寸，n为导流板数量。
增设导流结构4后可以使出风口的尺寸H变得更大，从而增大了出风面积，当出风通道3内的风流向出风口时，
风会先经过导流结构4，一部分被导流结构4改变流向，流向第三凹曲面211，另一部分风绕流至导流结构4的背风侧，并经过背风侧后流出。
优选地，出风面板为天井式室内机的出风面板，角盖板2的最低点高于面板体1的最低点设置，从而有效避免凝露问题(因为如果两者平齐或者角盖板2的最低点低于面板体1的最低点设置，则风会直接从风道出来，两者的导流结构就不会起作用)。
实施例4
如图8所示，一种天井式空调内机，包括上述的出风面板。
本领域的技术人员容易理解的是，在不冲突的前提下，上述各优选方案可以自由地组合、叠加。
应当理解，上述的实施方式仅是示例性的，而非限制性的，在不偏离本申请的基本原理的情况下，本领域的技术人员可以针对上述细节做出的各种明显的或等同的修改或替换，都将包含于本申请的权利要求范围内。
