本发明提供了一种出风结构，请参考图1至图4，出风结构包括：出风部本体，出风部本体具有出风口40；导风板支架，导风板支架与出风部本体相连接，导风板支架设置在出风口40的下部；导风板20，导风板20可转动地设置在导风板支架上。
本发明的出风结构通过将导风板支架设置在出风口40的下部，导风板20可转动地设置在导风板支架上，从而可以方便导风板20的打开与闭合，在导风板20打开或闭合过程中，不会出现干涉的问题。其中，出风部本体具有出风口40，导风板支架与出风部本体相连接。本发明的出风结构通过将导风板支架设置在出风口40的下部，从而可以在导风板20打开或闭合过程中，不会出现干涉的问题，解决了现有技术中的出风结构的导风板不容易打开或闭合的问题。
在本实施例中，导风板20为出风结构的下导风板。
在本实施例中，可选地，导风板支架设置在出风口40的下部，即，导风板支架位于出风口40的内部靠近出风口40的下边缘的位置，可以理解为，导风板支架与外界空间较为接近。
在本实施例中，可选地，导风板支架设置在出风口40的下部，即，导风板支架位于出风口40的外部，且靠近出风口40的下边缘的位置。
考虑到导风板支架设置在出风口40的下部，即，导风板支架的下部容易产生凝露水，如图3所示，出风部本体上设置有引流通道80，引流通道80与出风口40相连通，导风板支架与引流通道80的通道壁相连接。
在本实施例中，通过在出风部本体上设置有引流通道80，其中，引流通道80与出风口40相连通，导风板支架与引流通道80的通道壁相连接，故，在气流流动过程中，由于引流通道80的存在，从而使得气流可以通过引流通道80吹到导风板支架上，以此降低了导风板支架与外界的温度差，避免了凝露水的产生。
在本实施例中，引流通道80设置在出风口40内。
优选地，引流通道80为凹槽。
针对引流通道80的具体结构，引流通道80的横截面为梯形，引流通道80沿气流的流动方向逐渐收缩。
优选地，引流通道80的相邻两个侧壁之间具有第二预设夹角b，其中，15°≤b≤85°。
可选地，40°≤b≤85°。
优选地，60°≤b≤80°。
在本实施例中，引流通道80为倒八字导风槽，导风板支架设置在引流通道80的中间位置。
倒八字导风槽的斜边与出风口下沿竖向位置成约10°～30°角，下端槽宽约8～15mm，槽深1～3mm；利用倒八字导风槽结构，迫使沿风道下表面吹出的冷风能够吹到导风板支架的下端面，从而强化了隔绝导风板支架的下表面上的室内热空气的能力，综合解决了支架易凝露滴水的问题。
针对导风板支架的具体结构，如图1和图2所示，导风板支架包括：支架本体10，支架本体10与导风板20相连接；支架本体10上设置有引流部30；其中，引流部30为凸起或凹陷中的至少一种。
在本实施例中，支架本体10上设置有引流部30，可以增加凝露的附着面积，从而可以避免凝露大量滴落。其中，支架本体10用于与导风板20相连接，引流部30为凸起或凹陷中的至少一种。
在本实施例中，通过在支架本体10上设置有引流部30，可以增加凝露的附着面积，避免了凝露大量汇集，减少了凝露的滴落量，解决现有技术中的导风板支架产生的凝露容易滴落的问题。
考虑到凝露水都集中于支架本体10的外边缘，引流部30设置在支架本体10的外边缘。
考虑到凝露水多产生于支架本体10的下边缘，引流部30设置在支架本体10的下边缘。
为了那个增加引入面积，引流部30为多个，多个引流部30沿支架本体10的外边缘间隔设置。
考虑到支架本体10靠近出风口的一侧会产生大量的凝露，支架本体10的部分的外边缘间隔设置多个引流部30。
在本实施例中，引流部30设置在支架本体10的外边缘，引流部30为多个，多个引流部30沿支架本体10的外边缘间隔设置，且支架本体10的部分的外边缘间隔设置多个引流部30，从而在可以增加引流面积的同时，又不用过多的增加支架本体10的附加结构，而只需在会产生凝露水的位置增加引流部30。
针对引流部30的具体结构，引流部30为凹槽，凹槽为矩形槽或V形槽。
在本实施例中，引流部30为凹槽，即，在支架本体10的外边缘面上设置有凹槽。
可续地，凹槽为矩形槽或V形槽。
针对引流部30的一个具体结构形式，引流部30为凹槽，凹槽的截面为梯形。
针对引流部30的具体组成，如图1和图2所示，引流部30包括底壁31、第一侧壁32和第二侧壁33，底壁31位于第一侧壁32和第二侧壁33之间，底壁31与第一侧壁32之间弧形过渡，和/或，底壁31与第二侧壁33之间弧形过渡。
在本实施例中，引流部30的截面为梯形，即，引流部30为梯形槽。其中，引流部30包括底壁31、第一侧壁32和第二侧壁33，底壁31位于第一侧壁32和第二侧壁33之间，底壁31、第一侧壁32和第二侧壁33为梯形槽的3个槽面。
通过将底壁31与第一侧壁32之间弧形过渡，和/或，底壁31与第二侧壁33之间弧形过渡，能够避免凝露水集中在某一位置，从而造成滴落。
优选地，底壁31所在平面与水平面之间具有第一预设夹角a，第一预设夹角a为锐角。
在本实施例中，底壁31所在平面与水平面之间具有第一预设夹角a，其中，水平面是相对于导风板支架的安装位置确定的，即，当导风板支架安装到位后，底壁31相对于水平面存在一定的倾斜度，通过倾斜度的设置，也可以增加凝露水的附着面积。
可选地，0≤a≤15.5°。
可选地，1.5°≤a≤15.5°。
优选地，3°≤a≤12°。
针对支架本体10的具体结构，如图1和图2所示，支架本体10包括：第一外边缘11；第二外边缘12，第二外边缘12与第一外边缘11相连接，沿气流流动方向，气流依次经过第一外边缘11和第二外边缘12；其中，第二外边缘12的至少部分设置有引流部30。
在本实施例中，支架本体10包括第一外边缘11和第二外边缘12，其中，第二外边缘12 与第一外边缘11相连接，沿气流流动方向，气流依次经过第一外边缘11和第二外边缘12，即，第二外边缘12更靠近外界空间，更容易产生凝露水，所以在第二外边缘12的至少部分设置有引流部30，从而避免凝露水集中。
相应地，支架本体10还包括：第三外边缘13，第三外边缘13与第二外边缘12相连接，第二外边缘12位于第一外边缘11和第三外边缘13之间；其中，第三外边缘13上设置有引流部30。
在本实施例中，第三外边缘13位于支架本体10的下部，即，第三外边缘13相对于第一外边缘11更靠近出风口40的下边缘，第三外边缘13更靠近外界空间。
在本实施例中，支架本体10包括第一外边缘11、第二外边缘12和第三外边缘13，第二外边缘12位于第一外边缘11和第三外边缘13之间，沿气流流动方向，气流可依次经过第一外边缘11、第二外边缘12和第三外边缘13，即，第三外边缘13相对于第二外边缘12更靠近外界空间，气流最后吹到第三外边缘13上，或者直接吹不到第三外边缘13，故，通过在第三外边缘13上设置有引流部30，提高第三外边缘13对凝露水的附着面积。
在本实施例中，可选地，气流可经第二外边缘12吹过第三外边缘13。
优选地，第三外边缘13为弧形面，第二外边缘12与第三外边缘13之间弧形过渡。
优选地，第三外边缘13相对于第一外边缘11向下倾斜。
优选地，第一外边缘11为平面，第二外边缘12为圆弧面。
优选地，第三外边缘13为弧面。
在本实施例中，支架本体10的下表面或前端面具有引流部30，引流部30可以做成矩形齿、V形齿、凹凸槽/点、晒纹、田字格等齿槽状结构。其中，齿宽1～2mm，齿高1～2mm。
通过引流部30设置为齿槽状表面，一方面齿形槽内可以积聚一些凝露水，增加下表面的积水或储水的能力。另一方面增大了支架本体10下表面积，进而增大了凝露水的附着面积，即使支架下表面产生一些凝露水也会延时滴落。
支架本体10伸出的长度方向向下倾斜，使下表面齿状表面与水平面形成3°～12°的角度；使支架本体10根部产生的冷凝水能够利用重力、附着力及毛细力作用均匀的分布在支架本体10的下表面，支架本体10倾斜角度过大或过小都能使产生的凝露水集聚成一大滴水而滴落。
针对出风部本体的具体结构，如图4所示，出风部本体包括：底壳；面板体50；其中，导风板支架设置在面板体50或底壳上。
在本实施例中，出风部本体包括：底壳和面板体50，其中，底壳和面板体50相连接。
在本实施例中，可选地，导风板支架设置在面板体50上。
可选地，导风板支架设置在底壳上。
在本实施例中，导风板支架位于出风口下沿的底壳或面板体50上，导风板支架伸出长度根据下导风板宽度、外观、强度等实际需要确定。支架宽度约3～6mm，高度约4～10mm，四周棱处倒圆角或倒斜角，利用附避效应，使风道内吹出的冷风尽量沿支架两侧面吹到导风板支架下端面，隔绝导风板支架表面上的室内热空气，进而隔绝冷凝水的产生。
考虑到出风结构的结构完整性，如图1所示，出风结构还包括：上导风板支架60，上导风板支架60与出风部本体相连接，上导风板支架60设置在出风口40的上部；上导风板70，上导风板70可转动地设置在上导风板支架60上。
在本实施例中，出风结构还包括：上导风板支架60和上导风板70，其中，上导风板支架60与出风部本体相连接，上导风板支架60设置在出风口40的上部，上导风板70可转动地设置在上导风板支架60上。
在本实施中，导风板20为下导风板，上导风板支架60与下导风板形成了整个导风结构。
针对上导风板支架60与下导风板的具体运行方式，导风板20具有第一位置和第二位置，上导风板70具有第三位置和第四位置，当导风板20位于第一位置，上导风板70位于第三位置时，导风板20与上导风板70遮挡在出风口40上；当导风板20位于第二位置，上导风板70位于第四位置时，导风板20与上导风板70露出出风口40。
优选地，导风板20沿第一方向由第一位置运动至第二位置，上导风板70沿第二方向由第三位置运动至第四位置，其中，第一方向为顺时针方向，第二方向为逆时针方向，或，第一方向为逆时针方向，第二方向为顺时针方向。
在本实施例中，出风结构的上导风板支架60与下导风板形成了全密封的导风结构，由于将导风板支架设置在了出风口40的下部，即将下导风板支架设置在了出风口40的下部，即使二者之间朝相反的两个方向打开出风口40，也不会出现干涉现象，从而不用在导风板与面板之间留有一定的避让间隙，从而在保证出风口40全密封的基础上，也可以方便实现出风口40的打开与闭合。
本发明还提供了一种空调器，包括出风结构，出风结构为上述的出风结构。
从以上的描述中，可以看出，本发明上述的实施例实现了如下技术效果：
本发明的出风结构通过将导风板支架设置在出风口40的下部，导风板20可转动地设置在导风板支架上，从而可以方便导风板20的打开与闭合，在导风板20打开或闭合过程中，不会出现干涉的问题。其中，出风部本体具有出风口40，导风板支架与出风部本体相连接。本发明的出风结构通过将导风板支架设置在出风口40的下部，从而可以在导风板20打开或闭合过程中，不会出现干涉的问题，解决了现有技术中的出风结构的导风板不容易打开或闭合的问题。
