Description

壁挂式空调室内机 技术领域
本发明涉及空气调节技术领域，特别涉及一种壁挂式空调室内机。
背景技术
现有技术中，空调室内机的出风口一般设置于空调外壳的底部。由于设置位置所限，出风口一般设计为长条形区域。这种出风口由于送风范围较窄，送风量也相应较少，无法满足用户需求。
另外，现有技术中，一般的空调室内机工作时，冷风从出风口直接吹出。空调的送风气流吹到人体上时，温度很低，用户会感觉非常不舒服，并很容易导致空调病。
发明内容
鉴于上述问题，提出了本发明以便提供一种克服上述问题或者至少部分地解决上述问题的壁挂式空调室内机，实现多样化送风，提升用户体验。
本发明一个进一步的目的是为了提高送风风量。
本发明另一个进一步的目的是为了提高用户舒适度。
本发明提供了一种壁挂式空调室内机，包括：壳体，壳体的前侧底部设置有沿空调室内机横向延伸的至少一个出风口；引流板，可运动地设置在出风口的下方，引流板与壳体的底部形成引流风道，引流板用于将空调室内机外部的气流导入引流风道，以使空调室内机的出风气流与空调室内机外部的气流混合后送出；和至少一个导风板，设置于出风口处，可绕平行于壁挂式空调室内机横向的一条轴线转动，以调节对应的贯流风扇的竖向出风方向，导风板配置成，在空调处于制冷状态时，转动至第一预设角度，以允许空调室内机外部的气流进入引流风道；在空调处于制热状态时，转动至第二预设角度，以阻止空调室内机外部的气流进入引流风道。
可选地，上述壁挂式空调室内机还包括：伸缩板，其一端可运动地设置于壳体内，另一端连接引流板的横向中央，用于驱动引流板相对于壳体伸缩运动，伸缩板配置成在壁挂式空调室内机开机时，驱动引流板伸出至第一预设位置。
可选地，伸缩板还配置成，在壁挂式空调室内机关机时，驱动引流板收缩至第二预设位置；导风板还配置成，在壁挂式空调室内机关机时，转动至第三预设角度，以与引流板配合共同封闭出风口。
可选地，引流板沿壁挂式空调室内机的横向延伸，其横截面呈椭圆形，其上表面为凸形曲面。
可选地，第一预设位置设置成：使得引流风道的宽度保持在20mm至30mm之间。
可选地，第一预设位置还设置成：引流板横截面的椭圆长轴与水平面的夹角为10°至20°；且引流板横截面的中心距离安装壁挂式空调室内机的墙体60mm至80mm。
可选地，上述壁挂式空调室内机还包括：两个贯流风扇，沿壁挂式空调室内机的横向同轴地设置于壳体内部，其中出风口的数量为两个，每个出风口与一个贯流风扇的位置相对应；伸缩板的一端伸入两个出风口之间的壳体内部。
可选地，上述壁挂式空调室内机两组摆叶组件，设置于出风口内侧，每组摆叶组件在壁挂式空调室内机的横向上与一个贯流风扇的位置相对应，用于调整对应的贯流风扇的横向出风方向。
可选地，每组摆叶组件包括：连杆，其主体沿壁挂式空调室内机的横向延伸设置，配置成可沿自身长度方向运动；和多片摆叶，间隔且可枢转地设置于连杆上，配置成在连杆的带动下沿壁挂式空调室内机的横向摆动。
可选地，每组摆叶组件还包括：步进电机，步进电机的输出端与对应的连杆相连，配置成驱动连杆运动；步进电机，还配置成驱动连杆在预设的横向范围内运动，以使得每组摆叶组件的摆叶在预设的角度范围内摆动。
本发明提供了一种壁挂式空调室内机，其具有可运动地设置在出风口的下方的引流板，用于将空调室内机外部的位于出风口下方的气流向出风口的前方进行导流以使空调室内机的出风与空调室内机外侧的气流混合后送出。在室内机制冷时，导风板转动至第一预设角度，导风板控制出风方向上行。引流风道的出口处产生负压，上述负压可带动引流风道后部的室内环境空气进入该引流风道与出风口的出风混合，增大出风量，同时这种自然风与制冷风混合，使出风更加柔和，用户可以感受到送风温度适宜，不会有过冷的感觉。在室内机制热时，导风板转动至第二预设角度，导风板控制出风方向下 行。此时，引流风道处也能够产生负压，但是由于制热出风方向接近竖直方向，导致上述负压方向随制热风下压，负压方向贴近引流板方向。从而引流板的倾斜角度正好阻挡室内环境空气进入引流风道内，这样制热时无混合风，出风温度不会降低，能够达到快速制热的效果。本发明的空调室内机，引流板设置在送风口下方，且可以与导风板配合使用，实现既可以在制冷时混合送风，又可以在制热时避免混合送风，增强了用户使用舒适度，提高了用户体验。
进一步地，本发明的空调室内机具有两组贯流风扇，以及两组独立可控的摆叶组件。该空调室内机每个贯流风扇可单独控制，两组摆叶可以同时向两侧摆，以增大室内机的送风面积；两组摆叶也可以同时向内侧摆动，在空调室内机的中间区域形成混流风，增加用户的舒适度；也可以单独开启一侧的贯流风扇和摆叶组件，减少室内机的输出功率，更加节能环保。本发明的空调室内机具有多种可调节的送风模式，提高了用户的使用体验。
根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。

具体实施方式
本发明实施例提供了一种壁挂式空调室内机，如图1、图2和图3所示，包括：壳体10、出风风道11、导风板12、摆叶组件30、引流板50和伸缩板40。
壳体10的前侧底部设置有沿空调室内机横向延伸的出风口111。壳体10内部还设置有蒸发器13、贯流风扇20和蜗壳14。蜗壳14横向设置于室内机内部，贯流风扇20横向设置于蜗壳14内部。在本实施例中，蒸发器13为三段式蒸发器，设置于贯流风扇20外侧的前上方。
出风风道11设置于壳体10内部，其入口一端与蜗壳14的出口相连，其出口一端连通出风口。出风风道11用于将空调室内机蜗壳14内部与蒸发器13换热后的空气导向出风口。出风风道11由上风道壁和下风道壁共同限定出。
导风板12可以为一个也可以为多个。导风板12设置于出风口111处，可绕平行于壁挂式空调室内机横向的一条轴线转动，以调节对应的贯流风扇的竖向出风方向。在本实施例中，导风板12沿室内机横向延伸，其两端设置有与壳体10枢转连接的转轴，导风板12可以绕两端转轴的连线转动。导风板12位于引流板50的前上方，也就是说导风板12位于靠近出风风道11的上风道壁的位置。
引流板50设置在出风口111的下方，引流板50与壳体10的底部形成引流风道，用于将空调室内机外部的气流导入，以使空调室内机的出风气流与空调室内机外部的气流混合后送出。在本实施例中，引流板50同样沿壁挂式空调室内机的横向延伸，且其长度与室内机壳体的延伸长度相等。引流板50设置于导风板12的下后方，也就是说，引流板50和导风板12在前后方向和高度方向上均具有一定的间距。引流板50的作用是将室内机外部的气流引入，并与从室内机内部流出的气流混合，形成混流风(如图2所示的气流示意图)。在增大出风量的同时，使用室内的空气中和由出风口111送出的冷空气，使得送风气流温度适宜，达到让用户体感舒适的效果。在本实施例中，引流板50可运动地设置于出风口111的下方。在本发明另一些实施例中，引流板50也可以固定不动地设置于出风口111的下方，即引流板50始终保持在一个位置上(即第一预设位置)。
在本实施例中，伸缩板40连接壳体和引流板50的横向中央，用于驱动 引流板50相对于壳体10运动，以根据空调室内机的工作状态，调整引流板50的工作位置。伸缩板40的一端位于壳体10内部，且能够在壳体10内部运动，伸缩板40的另一端连接壳体和引流板50的横向中央，以保证引流板50能够平稳运动。本实施例的空调室内机还包括：电机和齿轮15。电机固定设置于壳体内部，齿轮设置于电机的输出端。伸缩板40的一面设置有齿条41，伸缩板40通过齿条41与齿轮15啮合，电机配置成驱动伸缩板40运动。
上述引流板50的横截面呈椭圆形，其上表面为凸形曲面，能够提高引流效果。在空调室内机开机时，伸缩板40驱动引流板伸出至第一预设位置，如图2、图3和图5所示。上述第一预设位置具体设置为：如图2所示，引流板50横截面的椭圆长轴与水平面的夹角α呈10°至20°，引流板横截面的中心距离安装壁挂式空调室内机的墙体的长度L1为60mm至80mm。引流风道的宽度L2设置为20mm至30mm之间，也就是说，引流板50的上表面与壳体10下表面的间距设定为20mm至30mm。经过发明人多次实验发现，当引流板50设置成上述第一预设位置时，引流效果最佳。
伸缩板40还配置成，在壁挂式空调室内机关机时，驱动引流板50收缩至第二预设位置。导风板12还配置成，在壁挂式空调室内机关机时，转动至第三预设角度，以与引流板50配合共同封闭出风口111。上述第二预设位置具体设置为：如图4所示，引流板50的长轴的一端贴靠出风口111的下边缘，引流板50本身处于水平状态。上述第三预设角度可以为导风板与竖直方向的夹角为45°左右，且导风板的上边缘突出于下边缘，从而使得导风板的上边缘抵靠出风口111的上边缘，导风板的下边缘抵靠引流板50。导风板12和引流板50共同封闭出风口111。本实施例的空调室内机，在关机时，引流板50缩至与导风板12平齐，共同封闭出风口111，如图4所示。此状态既可以遮挡出风口111处的缝隙，阻挡灰尘进入机体内，也可以阻挡灰尘落到引流板50引流面，影响空气洁净度，同时，使得室内机外型更加完整、美观。
导风板还配置成，在空调处于制冷状态时，转动至第一预设角度，以允许空调室内机外部的气流进入引流风道；在空调处于制热状态时，转动至第二预设角度，以阻止空调室内机外部的气流进入引流风道。上述第一预设角度设置为，导风板与水平方向的夹角小于30°，如图2所示。也就是说，当 导风板转动至第一预设角度时，导风板几乎水平设置。上述第二预设角度设置为，导风板与竖直方向的夹角小于30°，如图3所示。也就是说，当导风板转动至第二预设角度时，导风板几乎竖直设置。
在室内机制冷时，导风板12转动至第一预设角度，导风板12控制出风方向上行(即接近于水平出风)。引流风道的出口处产生负压，上述负压可带动引流风道后部的室内环境空气进入该引流风道与出风口111的出风混合，增大出风量，同时这种自然风与制冷风混合，使出风更加柔和，用户可以感受到送风温度适宜，不会有过冷的感觉。在室内机制热时，导风板12转动至第二预设角度，导风板12控制出风方向下行(即接近于竖直出风)。此时，引流风道处也能够产生负压，但是由于制热出风方向接近竖直方向，导致上述负压方向随制热风下压，负压方向贴近引流板50方向。从而引流板50的倾斜角度正好阻挡室内环境空气进入引流风道内，这样制热时无混合风，出风温度不会降低，能够达到快速制热的效果。本实施例的空调室内机，引流板50设置在送风口下方，且可以与导风板12配合使用，实现既可以在制冷时混合送风，又可以在制热时避免混合送风，增强了用户使用舒适度，提高了用户体验。
本实施例的壁挂式空调室内机具有两个贯流风扇和两个导风板12。两个贯流风扇20沿空调室内机横向同轴地排列于壳体10内部，也就是说多个贯流风扇20的转轴在同一条直线上。优选地，多个贯流风扇20的大小和长度均相同。伸缩板40的一端连接两个出风口111之间的壳体10，也就是伸缩板40连接壳体10的横向中间的位置。两个导风板12设置于出风口111处，每个导风板12在空调室内机的横向上与一个贯流风扇20的位置相对应，配置成绕平行于空调室内机横向的一条轴线转动，以调节对应的贯流风扇20的竖向出风方向。
如图6所示，每个贯流风扇20还包括：风扇电机21，设置于贯流风扇20远离另外一个贯流风扇20的一端，配置成驱动贯流风扇20转动。上述两个风扇电机21可以同时运行，以驱动两个风扇同时转动，也可以单独开启其中一个风扇电机21，以使得两个风扇中的其中一个处于运行状态，另一个停止送风。
每个贯流风扇20均配置各自独立的摆叶组件30。在本实施例中，空调室内机包括两组摆叶组件30。两组摆叶组件30设置于出风口111内侧，每 组摆叶组件30在空调室内机的横向上与一个贯流风扇20的位置相对应，并为对应的贯流风扇20提供导风功能。每个贯流风扇20还配置有：风扇电机21。风扇电机21设置于贯流风扇20远离另外一个贯流风扇20的一端，用于驱动贯流风扇20转动。上述两个风扇电机21可以同时运行，以驱动两个风扇同时转动，也可以单独开启其中一个风扇电机21，以使得两个风扇中的其中一个处于运行状态，另一个停止送风。
两组摆叶组件30设置于出风口111内侧，每组摆叶组件30在空调室内机的横向上与一个贯流风扇20的位置相对应，并为对应的贯流风扇20提供导风功能。
如图6所示，每组摆叶组件30包括：连杆31、多片摆叶32和步进电机321。连杆31沿空调室内机的横向延伸设置，连杆31可沿自身长度方向运动。多片摆叶32间隔且可枢转地设置于连杆31上，在连杆31沿自身长度方向运动时，带动多个摆叶32沿空调室内机的横向左右摆动。具体地，每片摆叶32的根部具有一个短杆，短杆上设置有两个枢转轴，其中第一个枢转轴位于短杆的末端，连接连杆31，第二个枢转轴、即摆叶转轴连接位于摆叶32上方的蜗舌条。在连杆31横向运动的过程中，每片摆叶32绕摆叶转轴左右摆动。当摆叶32向左摆动时，贯流风扇20向空调室内机左侧出风；当摆叶32向右摆动时，贯流风扇20向空调室内机右侧出风。上述两个摆叶组件30左右对称设置，两个连杆31在同一条直线上。
本实施例的空调室内机具有两组贯流风扇20，以及两组独立可控的摆叶组件30。该空调室内机每个贯流风扇20可单独控制，两组摆叶32可以同时向两侧摆，以增大室内机的送风面积；两组摆叶32也可以同时向内侧摆动，在空调室内机的中间区域形成混流风，增加用户的舒适度；也可以单独开启一侧的贯流风扇20和摆叶组件30，减少室内机的输出功率，更加节能环保。本实施例的空调室内机具有多种可调节的送风模式，提高了用户的使用体验。
本领域技术人员应理解，在没有特别说明的情况下，本发明实施例中所称的“上”、“下”、“左”、“右”、“横”、“竖”、“前”、“后”等用于表示方位或位置关系的用语是以空调器室内机的实际使用状态为基准而言的，这些用语仅是为了便于描述和理解本发明的技术方案，而不是指示或暗示所指的装置或部件必须具有特定的方位，因此不能理解为对本发明 的限制。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
