技术领域
本发明涉及空调技术领域，特别涉及一种导风板以及空调器。
背景技术
随着生活水平的日益提高，人们对空调器的功能性要求也越来越高。现在的空调器中，导风板转动所需的运动空间较大，而为了保证空调器的外观尺寸不变，需要减少外壳的用料，这可能导致外壳的强度较低，影响空调器的使用寿命，并且导风板在转动过程中受力不均，容易导致导风板转动不流畅，甚至发生卡顿的情况，影响用户体验。
发明内容
本发明解决的问题是如何减小导风板转动所需的运动空间，并且保证导风板在转动过程中受力均匀，避免其发生转动不流畅甚至卡顿的情况，提升用户体验。
为解决上述问题，本发明的技术方案是这样实现的：
第一方面，本发明提供了一种导风板，应用于空调器，导风板包括板体，板体的横截面呈弧形设置，板体的转动轴心位于板体的最长弦的中垂线上。与现有技术相比，本发明提供的导风板由于采用了转动轴心位于板体的最长弦的中垂线上的板体，所以能够减小导风板转动所需的运动空间，并且保证导风板在转动过程中受力均匀，避免其发生转动不流畅甚至卡顿的情况，提升用户体验。
进一步地，板体的转动轴心与板体的圆心不重合。以使板体的转动轨迹与板体所呈弧形的延伸方向不重合，从而便于利用板体调整空调挂机的出风方向，实现空调挂机出风方式的多样性。
进一步地，板体的圆心位于板体的最长弦的中垂线上，板体的转动轴心位于板体和板体的圆心之间。以进一步地减小导风板转动所需的运动空间，防止导风板在转动过程中与空调挂机内的零部件发生干涉。
进一步地，板体的内径范围为27毫米至30毫米；和/或，板体的圆心和板体的转动轴心的间距范围为7.8毫米至9.2毫米。合理的板体的内径以及板体的圆心和板体的转动轴心的间距能够在保证导风效果的同时尽量减小导风板转动所需的运动空间，防止导风板与空调挂机内的零部件发生干涉。
进一步地，板体密布设置有多个第一微孔，第一微孔用于供出风气流通过，任意两个第一微孔的出风方向之间形成的夹角小于或者等于42度。从第一微孔流出的出风气流风量和风速极低，出风气流缓慢地从多个第一微孔流出，以实现空调挂机的零风感出风功能，并且保证零风感出风时的换热效果。
进一步地，导风板还包括连接块，连接块连接于板体的内凹面，连接块用于与安装架转动连接。
进一步地，导风板还包括加强筋，加强筋连接于板体和连接块之间。加强筋用于提高板体和连接块的连接强度，从而提高整个导风板的强度，防止导风板发生变形或者断裂的情况。
第二方面，本发明提供了一种空调器，包括外壳以及上述的导风板，外壳设置有导风空间，导风空间的外侧具有出风口，导风板可转动地安装于导风空间内，导风板用于对吹入导风空间内的出风气流进行导向，并使其从出风口排出，该导风板包括板体，板体的横截面呈弧形设置，板体的转动轴心位于板体的最长弦的中垂线上。空调器能够减小导风板转动所需 的运动空间，并且保证导风板在转动过程中受力均匀，避免其发生转动不流畅甚至卡顿的情况，提升用户体验。
进一步地，外壳包括中框和前面板，前面板安装于中框的外侧，前面板和中框之间形成辅助出风通道，导风板还用于将出风气流导入辅助出风通道，前面板密布设置有多个第二微孔，第二微孔与辅助出风通道连通，第二微孔用于供辅助出风通道内的出风气流排出。从第二微孔流出的出风气流风量和风速极低，出风气流缓慢地从前面板上的第二微孔流出，以实现空调器的零风感出风功能。
进一步地，导风板的数量为两个，分别为第一导风板和第二导风板，第一导风板具有第一转动轴线，第二导风板具有第二转动轴线，第一转动轴线与第二转动轴线平行且间隔设置，第一导风板相对第二导风板靠近前面板设置，第一转动轴线位于第二转动轴线的斜上方。以使第一导风板和第二导风板的导风作用相辅相成，进一步地增强导风效果，提升用户体验。
进一步地，空调器还包括安装架，安装架与中框可拆卸连接，导风板可转动地安装于安装架上。安装架用于对导风板进行承载，导风板用于相对于安装架转动，以对出风气流进行导向。

具体实施方式
为使本发明的上述目的、特征和优点能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
第一实施例
请结合参照图1至图3，本发明实施例提供了一种导风板100，用于实现导风功能。其能够减小导风板100转动所需的运动空间，并且保证导风板100在转动过程中受力均匀，避免其发生转动不流畅甚至卡顿的情况，提升用户体验。
本实施例中，导风板100应用于空调挂机，空调挂机挂设于室内墙壁上，空调挂机能够向室内吹出热风或者冷风，以实现制热或者制冷的功能， 导风板100用于在空调挂机向外出风时对出风气流进行导向，以调整空调挂机的出风方向，满足用户需求。但并不仅限于此，在其它实施例中，导风板100可以应用于空调柜机，也可以应用于移动式空调，对导风板100的应用场景不作具体限定。
导风板100包括板体110、连接块120和加强筋130。板体110沿其宽度方向的横截面呈弧形设置，呈弧形设置的板体110风阻较小，具有良好的导风效果，并且板体110的两侧面均能够进行导风，以提高空调挂机出风方式的多样性。板体110相对设置有内凹面112和外凸面113，连接块120连接于板体110的内凹面112，连接块120用于与安装架300转动连接，连接块120用于承载板体110，板体110用于导风。具体地，连接块120具有一转动轴心，该转动轴心即为整个导风板100的转动轴心，连接块120能够沿其转动轴心相对安装架300转动，安装架300能够对连接块120进行限位，从而对板体110进行限位，保证板体110能够在连接块120的带动下沿板体110的转动轴心转动，防止板体110发生倾斜或者偏转的情况。
进一步地，板体110的转动轴心位于板体110的最长弦的中垂线上，板体110的最长弦即为板体110所呈弧形对应的弦。具体地，前述的中垂线并不是绝对意义上的中垂线，将板体110最长弦的中点与板体110的转动轴心作连线，在该连线与中垂线之间的夹角小于或者等于1度的范围内，均可视为测量误差，属于本方案的保护范围。这样一来，能够使得整个导风板100转动所需的运动空间达到最小程度，从而减小了导风板100转动所需的运动空间，并且由于板体110的最长弦的中垂线将板体110平分为两部分，所以位于该中垂线上的板体110的转动轴心能够保证导风板100在转动过程中受力均匀，避免其发生转动不流畅甚至卡顿的情况，提升用户体验。
需要说明的是，加强筋130连接于板体110和连接块120之间，加强筋130用于提高板体110和连接块120的连接强度，从而提高整个导风板100的强度，防止导风板100发生变形或者断裂的情况。
本实施例中，连接块120的数量为多个，多个连接块120间隔设置于板体110上，多个连接块120均用于与安装架300转动连接，以进一步地提高导风板100与安装架300配合的稳定性，防止导风板100脱离安装架300。相应地，加强筋130的数量同样为多个，每个加强筋130连接于板体110和一个连接块120之间，以进一步地提高整个导风板100的强度。
值得注意的是，板体110的转动轴心与板体110的圆心不重合，以使板体110的转动轨迹与板体110所呈弧形的延伸方向不重合，从而便于利用板体110调整空调挂机的出风方向，实现空调挂机出风方式的多样性。本实施例中，板体110的圆心位于板体110的最长弦的中垂线上，板体110的转动轴心位于板体110和板体110的圆心之间，即板体110的圆心设置于板体110的转动轴心远离板体110的一侧，以进一步地减小导风板100转动所需的运动空间，防止导风板100在转动过程中与空调挂机内的零部件发生干涉。
需要说明的是，板体110的内径范围为27毫米至30毫米；或者，板体110的圆心和板体110的转动轴心的间距范围为7.8毫米至9.2毫米；或者，在板体110的内径范围为27毫米至30毫米的同时，板体110的圆心和板体110的转动轴心的间距范围为7.8毫米至9.2毫米。合理的板体110的内径以及板体110的圆心和板体110的转动轴心的间距能够在保证导风效果的同时尽量减小导风板100转动所需的运动空间，防止导风板100与空调挂机内的零部件发生干涉。本实施例中，板体110的内径为28毫米，板体110的圆心和板体110的转动轴心的间距为8.82毫米，但并不仅限于此，在其它实施例中，板体110的内径可以为27毫米，也可以为30毫米；板体110的圆心和板体110的转动轴心的间距可以为7.8毫米，也可以为9.2毫米；对板体110的内径以及板体110的圆心和板体110的转动轴心的间距不作具体限定。
为了便于理解，将板体110的最长弦表示为AB线段，将板体110的最长弦的中点表示为C点，将板体110的转动轴心表示为D点，将板体110 的最长弦的中垂线表示为CD两点所在直线，将板体110的圆心表示为E点，将板体110的内径表示为r。
本实施例中，板体110密布设置有多个第一微孔111，第一微孔111用于供出风气流通过，以实现空调挂机的零风感出风功能。具体地，当空调挂机处于零风感出风状态时，导风板100关闭，出风气流能够通过板体110上的多个第一微孔111向室内流出，由于第一微孔111的直径较小，所以从第一微孔111流出的出风气流风量和风速极低，出风气流缓慢地从多个第一微孔111流出，以实现空调挂机的零风感出风功能，并且保证零风感出风时的换热效果。
进一步地，任意两个第一微孔111的出风方向之间形成的夹角小于或者等于42度，即任意两个第一微孔111的开设方向之间形成的夹角小于或者等于42度。这样一来，在便于制造生产的前提下，能够有效减小第一微孔111所造成的风阻影响，避免产生噪音，同时由于多个第一微孔111存在不同朝向，所以能够利用其调整出风气流的出风方向，使得出风方向更加分散，提升零风感出风的效果。
本发明实施例所述的导风板100，板体110的横截面呈弧形设置，板体110的转动轴心位于板体110的最长弦的中垂线上。与现有技术相比，本发明提供的导风板100由于采用了转动轴心位于板体110的最长弦的中垂线上的板体110，所以能够减小导风板100转动所需的运动空间，并且保证导风板100在转动过程中受力均匀，避免其发生转动不流畅甚至卡顿的情况，提升用户体验。
第二实施例
请结合参照图4和图5，本发明提供了一种空调器10，用于调控室内气温。该空调器10包括外壳200、安装架300、驱动电机400和导风板100。其中，导风板100的基本结构和原理及产生的技术效果和第一实施例相同，为简要描述，本实施例部分未提及之处，可参考第一实施例中相应内容。
本实施例中，空调器10为空调挂机，空调器10挂设于室内墙壁上，空调器10能够向室内吹出热风或者冷风，以实现温度调控功能。具体地，导风板100用于在空调器10向外出风时对出风气流进行导向，以调整空调器10的出风方向，导风板100能够使得空调器10可以实现不同的出风模式，从而提高空调器10出风的多样性。
需要说明的是，外壳200设置有导风空间210，导风空间210的外侧具有一出风口220，导风空间210用于与蜗壳风道500连接，安装于蜗壳风道500内的贯流风机600能够产生负压，以带动出风气流通过蜗壳风道500流入导风空间210。具体地，导风板100可转动地安装于导风空间210内，导风板100用于对吹入导风空间210内的出风气流进行导向，并使其从出风口220排出，以实现调整空调器10出风方向的功能。
外壳200包括中框230和前面板240。前面板240安装于中框230的外侧，前面板240用于对中框230进行遮蔽，以提高整个空调器10的美观度。前面板240和中框230之间形成辅助出风通道250，导风板100还用于将出风气流导入辅助出风通道250，前面板240密布设置有多个第二微孔241，第二微孔241与辅助出风通道250连通，第二微孔241用于供辅助出风通道250内的出风气流排出，辅助出风通道250内的出风气流能够同时通过多个第二微孔241向外流出，由于第二微孔241的直径较小，所以从第二微孔241流出的出风气流风量和风速极低，出风气流缓慢地从前面板240上的第二微孔241流出，以实现空调器10的零风感出风功能。
本实施例中，安装架300与中框230可拆卸连接，导风板100可转动地安装于安装架300上，安装架300用于对导风板100进行承载，导风板100用于相对于安装架300转动，以对出风气流进行导向。驱动电机400安装于外壳200上，且与导风板100传动连接，驱动电机400用于带动导风板100转动，以实现导风板100转动角度的电控调节。
导风板100的数量为两个，分别为第一导风板140和第二导风板150。 第一导风板140具有第一转动轴线，第二导风板150具有第二转动轴线，第一转动轴线与第二转动轴线平行且间隔设置，以使第一导风板140和第二导风板150的导风作用相辅相成，进一步地增强导风效果，提升用户体验。具体地，第一导风板140相对第二导风板150靠近前面板240设置，即第一导风板140设置于第二导风板150靠近前面板240的一侧，第一转动轴线位于第二转动轴线的斜上方(上下方向即为竖直方向)。当空调器10处于零风感出风状态时，第二导风板150用于将出风气流朝第一导风板140所在区域导流，第一导风板140用于将出风气流朝辅助出风通道250内导流，以使出风气流连续不断地进入辅助出风通道250，从而使得出风气流持续地从第二微孔241流出，实现零风感出风功能。在应用中，也可以采用多个导风板的形式，只要能够满足第一导风板140和第二导风板150的功能即可。
进一步地，驱动电机400的数量为两个，分别为第一驱动电机410和第二驱动电机420。第一驱动电机410与第一导风板140传动连接，第一驱动电机410用于带动第一导风板140转动，第二驱动电机420与第二导风板150传动连接，第二驱动电机420用于带动第二导风板150转动。具体地，第一驱动电机410和第二驱动电机420独立运行，即第一导风板140的动作和第二导风板150的动作互不干涉，用户可以只运转第一导风板140而不运转第二导风板150，也可以只运转第二导风板150而不运转第一导风板140，以提高空调器10出风的多样性。
请结合参照图6至图11(图6至图11中的线条箭头表示空气流动方向)，需要说明的是，空调器10具有六种模式，分别为零风感模式、强化制热模式、普通制热模式、制冷模式、恒温模式和双区送风模式。其中，零风感模式的出风量和出风速度都极低，用户基本感受不到出风气流直吹，舒适度较高，此模式既可以进行制热，又可以进行制冷，适用于用户睡眠或者办公的场景；强化制热模式的出风量和出风速度都较高，出风气流沿竖直向下的方向吹出至地面，再从地面向四周和上方扩散，以快速实现制热功 能，适用于室内温度极低亟需升温的场景；普通制热模式的出风量和出风速度都较高，出风气流沿第一方向倾斜向下吹出，热量持续向下扩散，以实现制热保持功能，适用于室内温度升高至一定程度后需要保持的场景；制冷模式的出风量和出风速度都较高，出风气流沿第二方向倾斜向下吹出，冷量持续向下扩散，以实现制冷保持功能，适用于室内温度降低至一定程度后需要保持的场景；恒温模式的出风量和出风速度都较低，出风气流沿第三方向倾斜向下吹出，此模式既可以进行制热，又可以进行制冷，适用于室内温度完全达到用户需求后需要保持的场景；双区送风模式的出风量和出风速度可根据用户需求调节，出风气流沿两个不同的方向向外吹出，此模式既可以进行制热，又可以进行制冷，适用于需要对室内的不同位置同时进行温度调控的场景。
具体地，第一方向与水平方向之间形成第一夹角，第二方向与水平方向之间形成第二夹角，第三方向与水平方向之间形成第三夹角，第一夹角大于第三夹角，第三夹角大于第二夹角，即普通制热模式吹出的出风气流相较于恒温模式吹出的出风气流更低，恒温模式吹出的出风气流相较于制冷模式吹出的出风气流更低。为了便于理解，将第一夹角表示为a，将第二夹角表示为b，将第三夹角表示为c。
当空调器10处于零风感模式时，第一导风板140和第二导风板150均转动至中间位置，此时第一导风板140和第二导风板150的内凹面112正对蜗壳风道500设置，以起到兜风的作用，将出风气流朝靠近辅助出风通道250的方向导流。具体地，从蜗壳风道500吹出的出风气流吹至第一导风板140和第二导风板150的内凹面112时，一部分出风气流直接通过第一导风板140和第二导风板150上开设的第一微孔111向外流出，实现第一导风板140和第二导风板150区域位置的零风感出风，另一部分出风气流在第一导风板140和第二导风板150的内凹面112的导流作用下流入辅助出风通道250，并通过前面板240上开设的第二微孔241向外流出，实现前面板240区域位置的零风感出风。这样一来，能够有效提高零风感出风 的风量，保证换热效果。
当空调器10处于强化制热模式时，第一导风板140和第二导风板150均转动至左极限位置，此时第一导风板140的外凸面113正对辅助出风通道250设置，以将辅助出风通道250挡住，防止出风气流朝辅助出风通道250内流动，而第二导风板150的外凸面113正对第一导风板140设置，以避免将出风气流导流至第一导风板140所在区域。具体地，从蜗壳风道500吹出的出风气流一部分沿着第一导风板140的内凹面112折弯后沿竖直向下的方向流动，另一部分沿着第二导风板150的内凹面112折弯后沿竖直向下的方向流动，在此过程中，可能会有些微的出风气流穿过第一导风板140和第二导风板150上开设的第一微孔111，但是由于出风方向与第一微孔111的开设方向不同，所以这些出风气流可以忽略不计。这样一来，第一导风板140和第二导风板150同时起到导风的作用，保证出风气流竖直向下流动，提高导风精准度，增强导风效果。
当空调器10处于普通制热模式时，第一导风板140和第二导风板150均转动至右极限位置，此时第一导风板140的内凹面112正对辅助出风通道250设置，第二导风板150的内凹面112正对第一导风板140设置，第一导风板140的外凸面113和第二导风板150的内凹面112共同用于对出风气流进行导向。具体地，从蜗壳风道500吹出的出风气流流入第一导风板140的外凸面113和第二导风板150的内凹面112之间，第一导风板140的外凸面113和第二导风板150的内凹面112共同作用，以使出风气流沿第一方向倾斜向下流动，在此过程中，可能会有些微的出风气流穿过第一导风板140和第二导风板150上开设的第一微孔111，但是由于出风方向与第一微孔111的开设方向不同，所以这些出风气流可以忽略不计。这样一来，第一导风板140和第二导风板150同时起到导风的作用，保证出风气流沿第一方向倾斜向下流动，提高导风精准度，增强导风效果。
当空调器10处于制冷模式时，第一导风板140和第二导风板150均转动至中间位置与右极限位置之间的位置，此时第一导风板140和第二导风 板150的内凹面112均朝上设置，第一导风板140的内凹面112、第一导风板140的外凸面113和第二导风板150的内凹面112共同用于对出风气流进行导向。具体地，从蜗壳风道500吹出的出风气流一部分随着第一导风板140的内凹面112沿第二方向倾斜向下流动，另一部分流入第一导风板140的外凸面113和第二导风板150的内凹面112之间，第一导风板140的外凸面113和第二导风板150的内凹面112共同作用，以使出风气流沿第二方向倾斜向下流动，在此过程中，可能会有些微的出风气流穿过第一导风板140和第二导风板150上开设的第一微孔111，但是由于出风方向与第一微孔111的开设方向不同，所以这些出风气流可以忽略不计。这样一来，第一导风板140和第二导风板150同时起到导风的作用，保证出风气流沿第二方向倾斜向下流动，提高导风精准度，增强导风效果。
当空调器10处于恒温模式时，第一导风板140和第二导风板150均转动至中间位置与右极限位置之间的位置，此时第一导风板140和第二导风板150的内凹面112均朝斜上方设置，第一导风板140的内凹面112、第一导风板140的外凸面113和第二导风板150的内凹面112共同用于对出风气流进行导向。具体地，从蜗壳风道500吹出的出风气流一部分随着第一导风板140的内凹面112沿第三方向倾斜向下流动，另一部分流入第一导风板140的外凸面113和第二导风板150的内凹面112之间，第一导风板140的外凸面113和第二导风板150的内凹面112共同作用，以使出风气流沿第三方向倾斜向下流动，在此过程中，可能会有些微的出风气流穿过第一导风板140和第二导风板150上开设的第一微孔111，但是由于出风方向与第一微孔111的开设方向不同，所以这些出风气流可以忽略不计。这样一来，第一导风板140和第二导风板150同时起到导风的作用，保证出风气流沿第三方向倾斜向下流动，提高导风精准度，增强导风效果。
当空调器10处于双区送风模式时，第一导风板140转动至右极限位置，第二导风板150转动至左极限位置，此时第一导风板140和第二导风板150的外凸面113相对设置，第一导风板140的外凸面113、第二导风板150的 内凹面112和第二导风板150的外凸面113共同用于对出风气流进行导向。具体地，从蜗壳风道500吹出的出风气流一部分随着第二导风板150的内凹面112沿一个方向流动，另一部分流入第一导风板140的外凸面113和第二导风板150的外凸面113之间，第一导风板140的外凸面113和第二导风板150的外凸面113共同作用，以使出风气流沿另一个方向流动，两个方向完全不同，在此过程中，可能会有些微的出风气流穿过第一导风板140和第二导风板150上开设的第一微孔111，但是由于出风方向与第一微孔111的开设方向不同，所以这些出风气流可以忽略不计。这样一来，第一导风板140和第二导风板150同时起到导风的作用，以使出风气流能够同时从两个不同的方向向外吹出，提高导风精准度，增强导风效果。
本发明实施例所述的空调器10能够减小导风板100转动所需的运动空间，并且保证导风板100在转动过程中受力均匀，避免其发生转动不流畅甚至卡顿的情况，并且能够实现出风方式的多样性，满足用户的不同需求，提高导风精准度，增强导风效果，提升用户体验。
虽然本发明披露如上，但本发明并非限定于此。任何本领域技术人员，在不脱离本发明的精神和范围内，均可作各种更动与修改，因此本发明的保护范围应当以权利要求所限定的范围为准。
