首先，本领域技术人员应当理解的是，这些实施方式仅仅用于解释本申请的技术原理，并非旨在限制本申请的保护范围。本领域技术人员可以根据需要对其作出调整，以便适应具体的应用场合。例如，虽然本申请的空调内机是结合壁挂式空调内机来描述的，但是这并不是限定的，其他设备的空调内机也可配置本申请的空调内机，如柜式空调内机。
其次，需要说明的是，在本申请的描述中，术语“内”、“外”等指示的方向或位置关系的术语是基于附图所示的方向或位置关系，这仅仅是为了便于描述，而不是指示或暗示装置或构件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
此外，还需要说明的是，在本申请的描述中，除非另有明确的规定和限定，术语“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个构件内部的连通。对于本领域技术人员而言，可根据具体情况理解上述术语在本申请中的具体含义。
正如背景技术，发明人研究发现，导风板在关闭姿态下，导风板远离电机的一端会因重力而变形，导致导风板和出风口之间具有间隙的问题，而出现这种问题的原因在于，空调内机的内机骨架上设置的出风口为细长型的出风口，导风板设置在出风口处，导风板的形状为细长板件，导风板的长度方向的尺寸大于导风板的宽度方向的尺寸，导风板的长度方向的尺寸大致沿着水平方向设置，且导风板相对竖直方向倾斜设置，导风板的一端与电机的电机轴固定连接，导风板远离电机的一端就会因为重力作用而扭转变形，导致导风板与出风口之间具有间隙，空调内机的外观不美。
而且，发明人还研究发现，即使导风板背离电机的一端设置回转支撑件，且使得回转支撑件与导风板背离电机的一端固定连接，回转支撑件还与内机骨架转动连接，如此，一方面使得在电机轴的驱动下转动，导风板可以打开会关闭出风口，另一方面使得导风板背离电机的一端可以通过回转支撑件支撑在内部骨架上，但是，由于导风板的长度方向的尺寸远大于导风板的宽度方向的尺寸，导风板的长度方向的尺寸大致沿着水平方向设置，且导风板相对竖直方向倾斜设置，导风板与出风口之间依旧会存在间隙，导致空调内机的外观不美。即使在导风板的长度方向设置多个回转支撑件，空调使用一段时间后，导风板与出风口之间还是具有缝隙，空调内机的外观不美。
此外，发明人还研究发现，采用两个电机驱动导风板转动，两个电机分别设置在导风板的两端，这种方案虽然可以使得导风板遮挡出风口，闭合到位，但是两个电机会增加成本，且空调内机内部的空间有限，不利于两个电机的布局。
针对上述技术问题，本申请实施例提供一种空调内机，其通过设置转动配合件，且将转动配合件配置为包括转轴和设置在转轴一端的曲轴，转轴与内机骨架转动连接，曲轴与导风板背离电机轴的一端固定连接，导风板关闭出风口的姿态下，曲轴的中心相对转轴的回转中心往空调内部偏心，如此，使得导风板关闭出风口的姿态下，导风板背离电机轴的一端相对导风板与电机轴连接的一端扭转变形，且往空调内部变形，使得导风板背离电机轴的一端因曲轴导致的变形方向与导风板背离电机轴的一端因重力导致的变形方向相反，进而使得导风板关闭出风口，空调内机外观美观。
下面将详细地对本申请示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
本申请实施例提供一种空调内机和空调，空调包括本申请实施例的空调内机和空调外机，空调外机和本申请实施例的空调内机配合工作。下面以壁挂式空调内机为例，具体说明本申请实施例的空调内机。
请参阅图1和图2，本申请实施例的一种空调内机，其包括内机骨架100、导风板200、电机300以及转动配合件400。内机骨架100用于提供导风板200、电机300、转轴配合件的安装基准。导风板200用于关闭和打开内机骨架100上的出风口110。电机300用于驱动导风板200转动，进而使得导风板200打开和关闭出风口110。转动配合件400用于对导风件背离电机300的一端进行支撑，且保证导风板200的正常转动。
请参阅图2，内机骨架100上设置有出风口110，出风口110的形状为细长型。以壁挂式空调内机举例说明，出风口110的长度方向大致沿着水平方向，出风口110的宽度方向与竖直方向呈一夹角设置。上述导风板200位于出风口110处，且具有遮闭出风口110的关闭姿态和打开出风口110的打开姿态。
请参阅图2，内机骨架100包括第一板120、第二板130、第一侧板140和第二侧板150，第一侧板140和第二侧板150相对设置，第一侧板140和第二侧板150设置在第一板120的同一侧，第一侧板140和第二侧板150之间设置第二板130，第一侧板140、第二侧板150、第二板130以及第一板120围合出上述出风口110。
电机300安装在内机骨架100上，在图1和图2示出的实施例中，电机300安装在上述第一侧板140上，且位于第一侧板140背离第二侧板150的一侧。电机300的电机轴与导风板200的第一端固定连接，第一侧板140上设置有过孔141，电机300的电机轴穿装在过孔141内，电机轴的末端位于第一侧板140和第二侧板150之间。
请参阅图1、图3和图4，转动配合件400包括转轴410和设置在转轴410一端的曲轴420，曲轴420和转轴410固定连接。转轴410用于与内机骨架100转动连接，进而使得与曲轴420连接的导风板200的第二端支撑在内机骨架100上，且导风板200可以在电机300的驱动下转动。曲轴420的回转中心相对转轴410的回转中心偏心设置，转轴410转动的时候，曲轴420的中心绕着转轴410的回转中心转动，如此，曲轴420使得与曲轴 420连接的导风板200的第二端绕着转轴410的回转中心转动，进而使得导风板200的第二端相对导风板200的第一端扭转变形，以进一步使得导风板200遮闭出风口110。
转轴410与内机骨架100转动连接，且转轴410的回转中心和电机轴的回转中心重合，在图2和图3示出的实施方式中，转轴410和第二侧板150转动连接，第二侧板150上设置有转孔151，转轴410穿装在转孔151内，且曲轴420位于第一侧板140和第二侧板150之间。曲轴420与导风板200的第二端固定连接，在图2、图4和图5示出的实施方式中，导风板200朝向第二板130的内侧壁上设置有第一安装座210，第一安装座210上设置有第一安装孔211，曲轴420穿装在第一安装孔211内。
导风板200在关闭姿态下，曲轴420的中心相对转轴410的回转中心往内机骨架100的内部偏心，内机骨架100的内部在图2示出的实施方式中指第一板120背离出风口110的一侧，导风板200的第二端相对导风板200的第一端往内机骨架100的内部扭转变形，导风板200的第二端相对导风板200的第一端发生扭转变形，且导风板200的第二端相对导风板200的第一端往内机骨架100的内部扭转变形。
导风板200在打开姿态下，曲轴420的中心相对转轴410的回转中心往内机骨架100的顶部偏心，内机骨架100的顶部在图2示出的实施方式中指第二板130的位置，导风板200的第二端相对导风板200的第一端发生扭转变形，且导风板200的第二端向导风板200的第一端往内机骨架100的顶部扭转变形。
本申请实施例的空调内机，内机骨架100上设置有出风口110，电机300安装在内机骨架100上，电机300的电机轴与导风板200的第一端固定连接，导风板200具有关闭姿态和打开姿态，导风板200在关闭姿态下，导风板200遮闭出风口110，导风板200在打开姿态下，导风板200打开出风口110，导风板200在电机300的驱动下，在关闭姿态和打开姿态之间切换，如此，实现导风板200打开或关闭出风口110。
本申请实施例的空调内机，转动配合件400包括转轴410和设置在转轴410一端的曲轴420，转轴410和内机骨架100转动连接，且转轴410的回转中心与电机轴的回转中心重合，曲轴420和导风板200的第二端固定连接，曲轴420的中心相对转轴410的回转中心偏心设置。当电机300驱动导风板200的转动的时候，导风板200的第一端以电机轴的回转中心为转动中心以类似自传的方式转动，导风板200的第二端由于曲轴420的约束，绕着转轴410的回转中心发生类似公转的方式转动，导风板200的第二端相对导风板200的第一端会扭转变形。由于导风板200在关闭姿态下，曲轴420的中心相对转轴410的回转中心往内机骨架100的内部偏心，这使得导风板200的第二端相对导风板200的第一端不仅扭转变形，且导风板200的第二端相对导风板200的第一端更靠近内机骨架100的内部，此时，导风板200可以遮闭出风口110，空调内机的外观美观。
本申请实施例的空调内机，转动配合件400包括转轴410和设置在转轴410一端的曲轴420，转轴410和内机骨架100转动连接，且转轴410的回转中心与电机轴的回转中心重合，曲轴420和导风板200的第二端固定连接，导风板200的第二端通过安装在导风板200第二端的转动配合件400与内机骨架100转动连接，一方面保证了导风板200在电机300的驱动下相对内机骨架100转动，另一方面使得导风板200的第二端支撑在内机骨架100上，进而减小导风板200的第二端相对导风板200的第一端的变形量，使得导风板200遮闭出风口110，空调内机的外观美观。
本申请实施例的空调内机，导风板200在关闭姿态下，曲轴420的中心相对转轴410的回转中心往内机挂架的内部偏心，这使得与曲轴420固定连接的导风板200的第二端相对导风板200的第一端往内机挂架的内部扭转变形，而导风板200的第二端因重力作用相对导风板200的第一端往内机骨架100的外部变形，导风板200的第二端因曲轴420导致的变形与导风板200的第二端因重力导致的变形方向相反，如此，使得导风板200可以遮闭出风口110，空调内机的外观美观。
请参阅图3、图4和图5，曲轴420为设置在转轴410一侧的偏心凸起421，偏心凸起421的中心相对转轴410的回转中心偏心设置。偏心凸起421安装在上述的第一安装孔211内，且偏心凸起421和第一安装孔211之间可以通过过盈配合的方式使得偏心凸起421和导风板200上的第一安装座210固定连接。
导风板200在关闭姿态下，偏心凸起421的中心相对转轴410的回转中心往内机骨架100的内部偏心，这能够使得与偏心凸起421固定连接的第一安装座210的中心相对转轴410位于内机骨架100的内部，而第一安装座210设置在导风板200的第二端，这使得导风板200的第二端相对导风板200的第一端更靠近内机骨架100，导风板200的第二端遮闭出风口110，空调内机的外观美观。
以垂直转轴410的回转中心的平面为截面，偏心凸起421的外侧壁的断面形状为跑道形的环线，跑道型的环线包括相对设置的两个直线段以及相对设置的两个半圆线段，两个直线段和两个半圆线段围合出跑道形的环线。对应的，以垂直转轴410的回转中心的平面为截面，第一安装孔211的孔壁的断面形状为跑道形的环线，偏心凸起421设置在第一安装孔211内。
以垂直转轴410的回转中心的平面为截面，偏心凸起421的外侧壁的断面形状为跑道形的环线，第一安装孔211的孔壁的断面形状为跑道形的环线，可以在电机300驱动导风板200转动的时候，导风板200的第一安装座210可以将扭转作用施加给偏心凸起421，进而带动与偏心凸起421固定连接的转轴410在转孔151内转动，使得电机300驱动导风板200顺利转动，导风板200在打开姿态和关闭姿态之间任意切换。
请参阅图3，偏心凸起421上设置有第二凸起422和第二凹槽423，第二凸起422沿偏心凸起421的长度方向延伸设置，第二凹槽423的槽长方向沿偏心凸起421的长度方向延伸设置。第二凸起422的数量和第二凹槽423的数量均为多个，且第二凸起422和第二凹槽423间隔设置，多个第二凸起422和多个第二凹槽423沿偏心凸起421的外侧壁的周向排布设置。
