下面参考图1-图14描述根据本发明实施例的空调室内机100的开关门组件10。
根据本发明实施例的空调室内机100的开关门组件10包括：开关门安装板11、开关门12和用于驱动开关门12移动的驱动组件13。
开关门安装板11上设有容纳腔111，容纳腔111的一侧具有装配口112且另一侧封闭以形成容纳腔111的底壁113，开关门12在邻近和远离开关门安装板11的方向上可移动，且开关门12邻近容纳腔111的底壁113设置，驱动组件13为多个且均设在容纳腔111内，每个驱动组件13的一端穿过容纳腔111的底壁113后与开关门12相连，多个驱动组件13的一端在开关门12上均匀布置。可选地，这里的均匀布置是指多个驱动 组件13与开关门12的连接处彼此之间的间距相当，或者多个驱动组件13与开关门12的连接处彼此连接后形成的图形为等边几何形状、圆形等行政规则的图形，由此可以使多个驱动组件13对开关门12所施加的驱动力是均匀的，保证开关门12的移动平稳。
根据本发明实施例的空调室内机100的开关门组件10，通过将驱动组件13设在容纳腔111内，从而可以利用容纳腔111对驱动组件13进行保护，避免驱动组件13收到外力、暴力后发生位置改变或者损坏，由此可以提高开关门组件10的寿命。进一步地，由于每个驱动组件13的一端穿过容纳腔111的底壁113后与开关门12相连，也就是说，驱动组件13和开关门12之间具有一个实体的壁，这样驱动组件13的一端穿过容纳腔111的底壁113后，该底壁113可以对驱动组件13起到一定的支撑作用，这样可以提高驱动组件13对开关门12的驱动稳定性。此外，通过多个驱动组件13对开关门12进行驱动，从而可以进一步提高开关门12运动的平稳性，降低每个驱动组件13的力矩，进而可以降低开关门组件10的噪音。
下面将参考附图详细描述根据本发明实施例的空调室内机100的开关门组件10。
可选地，如图1-图5所示，开关门安装板11包括：框架114、安装部115和连接件116。框架114上设有通风通道1141，如附图所示，通风通道1141沿前后方向贯穿框架114且可以允许气流通过，通风通道1141的横截面可以大致形成为圆形，开关门12的形状与通风通道1141的形状相同。
其中，如图1所示，其为根据本发明实施例的开关门组件10的结构示意图，其中开关门12处于关闭状态，关闭状态时，开关门12关闭通风通道1141；如图2所示，其为根据本发明实施例的开关门组件10的结构示意图，其中开关门12处于打开状态，打开状态时，开关门12打开通风通道1141，其中图2中的箭头为开关门12的打开方向。在本发明实施例中，开关门12可以在前后方向上可移动。此处“前后方向”可以解释为，在空调室内机100安装到位后，朝向客户的一侧为空调室内机100的前侧，朝向安装壁面的一侧为空调室内机100的后侧。
安装部115设在通风通道1141内，容纳腔111形成在安装部115上且容纳腔111的装配口112位于安装部115的远离开关门12的一侧。可选地，容纳腔111的装配口112位于安装部115的后侧，驱动组件13由后向前，经装配口112设置在容纳腔111内部。驱动组件13的前端穿过容纳腔111的底壁113后与开关门12相连。

可选地，如图3-图5所示，驱动组件13为三个，三个驱动组件13分别沿等边三角形的三条边定向设置。也就是说，每个驱动组件13可以形成为大致直线型结构，即每个驱动组件13的横截面可以为平直结构，三个驱动组件13可以分别沿等边三角形的三条边定向设置，由此三个驱动组件13的位置构造形成为平稳的三角形，在于开关门12相连后，与开关门12的连接处也形成为三角形，这样可以使开关门12的开关动作更加平稳。
当然本发明并不限于此，只要三个驱动组件13的一端在开关门12上均匀布置即可，三个驱动组件13还可以围成其他规则的形状，例如圆形、椭圆形、其他的正多边形，只要三个驱动组件13的对开关门12的施加的外力均匀即可。
当然本发明并不限于此，驱动组件13的数量还可以是两个、四个、五个、甚至更多个。
可选地，每个驱动组件13的结构均相同，由此一方面增加了零件的通用性减少开模件数量，另一方面面还可以提高生产效率。
如图9所示，可选地驱动组件13包括电机131、齿轮132和齿条133，齿轮132套设在电机131的电机131轴上，齿条133沿开关门12的移动方向延伸且与齿轮132可啮合传动，齿条133的一端穿过容纳腔111的底壁113后与开关门12相连。通过齿轮132齿条133结构作为驱动组件13，可以使驱动结构简单、驱动力矩平稳。
如图9所示，驱动组件13还包括：外壳134，电机131和齿轮132均设在外壳134内，齿条133在外壳134内可移动且齿条133的长度两端分别穿出外壳134。通过设置外壳134，从而可以将电机131、齿轮132和齿条133进行保护，保证驱动组件13的结构稳定性和避免受到外力的损害。此外，通过设置外壳134，从而可以方便驱动组件13在开关门安装板11上的安装，安装更加灵活。
其中可选地，齿轮132转动运动，驱动齿条133沿开关门12的运动方向运动，也就是驱动齿条133沿前后方向运动，从而可以利用齿条133驱动开关门12运动。
可选地，驱动组件13还包括：连接部135，连接部135设在齿条133的邻近开关门12的一端，连接部135与开关门12相连，通过设置连接部135，从而可以方便齿条133与开关门12相连。
可选地，连接部135包括连接板体1351和连接柱1352，连接板体1351的一侧面与齿条133垂直相连，连接柱1352设在连接板体1351的另一侧面上且可拆卸地与开关门12相连。如图9所示，连接板体1351的后侧面与齿条133垂直相连，连接板体1351的前侧面上设有连接柱1352。连接部135可穿过容纳腔111的底壁113后与开关门12 相连，其中如图10、图14所示，当开关门12处于打开状态时，齿条133的一部分也可以向前移动出容纳腔111。
如图10、图14所述，连接板体1351的前侧面还可以与开关门12的后壁面接触，这样可以提高与开关门12的连接结构稳定性，避免开关门12与连接部135之间产生晃动。
可选地，连接柱1352可以包括多个，多个连接柱1352的至少一个与开关门12可以通过卡扣结构相连，多个连接柱1352的至少一个可以通过螺纹连接件与开关门12相连。也就是说，连接部135与开关门12之间可以同时通过螺纹连接件以及卡扣结构相连，由此可以提高连接稳定性。
可选地，如图11所示，开关门组件10，其特征在于，开关门12包括底板121和盖板122，盖板122设在底板121的远离开关门安装板11的一侧，盖板122相对于底板121可拆卸。底板121和盖板122之间形成有空腔，这样一方面可以提高开关门组件10强度，另一方面可以避免制冷运行时在开关门12表面形成凝露水珠。
如图10、图11、图14所示，开关门组件10还包括导向部15，导向部15设在底板121的邻近开关门安装板11的一侧，开关门安装板11上设有导向槽，导向部15在导向槽内可移动。通过导向部15和导向槽的配合结构，从而可以提高开关门12在前后方向上移动的平稳性，开关门12可以顺利的打开和关闭通风通道1141，避免晃动。
如图10、图11、图14所示，可选地，底板121的中部设有朝向盖板122凸出的凸出部1211，凸出部1211的远离盖板122的一侧设有安装槽1212，导向部15设在安装槽1212内。由此导向部15在底板121上的安装结构稳定。可选地，底板121和导向部15可拆卸的相连，从而可以方便更换相应部件。
可选地，导向部15包括端壁151和围绕端壁151周向设置的周壁152，端壁151和部分周壁152容纳在安装槽1212内，周壁152还可移动地设在导向槽内。如图14所示，周壁152的前部可以容纳在安装槽1212内，周壁152的后部在导向槽内可移动。
可选地，如图14所示，开关门12的底板121和导向部15的端壁151之间可以通过凸起、凹槽结构配合连接，开关门12的底板121和导向部15的端壁151彼此贴合。连接部135上的连接柱1352可同时穿过开关门12的底板121和导向部15的端壁151，从而与开关门12进行连接，可选地，连接板体1351可与导向部15的端壁151贴合。
在本发明可选的实施例中，如图6-图8所示，开关门组件10还可以包括密封罩14。密封罩14设在开关门安装板11上且封盖容纳腔111的装配口112。
通过设置密封罩14封盖容纳腔111的装配口112，从而可以避免空调运行时换热后的空气进入到容纳腔111内，避免冷空气吹进容置腔内产生凝露，由此提高了驱动组件 13运行空间的密闭性，能够提升驱动组件13的使用寿命，同时能够避免人手能够从外面摸到电线，提高了机器运行的安全性。
可选地，如图6-图8所示，密封罩14和开关门安装板11之间可拆卸的相连。由此可以方便拆卸密封罩14，对内部的驱动组件13进行检修。可选地，密封罩14和开关门安装板11之间可以通过螺纹连接件相连，也可以通过卡扣结构相连。
可选地，密封罩14和开关门安装板11中的一个上设有卡扣141，且另一个上设有卡槽142，卡扣141与卡槽142卡接。由此可以方便密封罩14和开关门安装板11的安装和拆卸，减少工具的使用。
进一步地，如图7所示，可选地，开关门安装板11上围绕容纳腔111的装配口112设有多个卡槽142，密封罩14的朝向开关门安装板11的一侧设有多个卡扣141，多个卡扣141与多个卡槽142一一对应卡接。由此，密封罩14和开关门安装板11通过多组卡扣卡槽结构进行安装，安装结构更加稳定，彼此不易脱落。
进一步地，多个卡槽142均形成在开关门安装板11的安装部115上。其中，如图7所示，多个卡槽142可以形成安装部115的后端面上且围绕容纳腔111的装配口112的周向设置。由此，密封罩14通过卡扣141连接在安装部115上，并且封盖该容纳腔111的装配口112。由此，安装部115和密封罩14将容纳腔111进行密封，以使容纳腔111形成为与外界相对隔绝的环境，从而保证了驱动组件13的设置安全性。
如图6和图7所示，开关门安装板11上设有走线槽117，走线槽117与容纳腔111连通。其中走线槽117用于容纳连接驱动组件13和外部电源的电线，通过设置走线槽117从而可以方便电线的安装，而且电线容纳在走线槽117内可以防止电线收到外力被损坏，由此提高安全性。可选地，走线槽117的开口与容纳腔111的装配口112的朝向相同。
可选地，如图6-图8所示，所密封罩14上设有线槽盖板143，线槽盖板143封盖走线槽117。通过设置线槽盖板143，从而可以避免电线暴露在外，避免人手触摸到电线，降低安全隐患，满足安规要求。
可选地，如图6-图8，密封罩14上设有向远离容纳腔111的方向凸出的凸出槽144，凸出槽144可容纳齿条133。驱动组件13在驱动开关门12沿前后方向移动的过程中，齿条133也沿前后方向移动，通过在密封罩14上设置凸出槽144，从而为齿条133的运动提供避让空间，这样可以减小容纳腔111的容积，提高产品的空间利用率。
下面将参考图12-图14描述根据本发明第二方面实施例的空调室内机100，其中，需要说明的是，空调室内机100可以是柜机，也可以是挂机。
根据本发明实施例的空调室内机100包括：外箱底板部件20、面板部件30和空调 室内机100的开关门组件10。其中空调室内机100的开关门组件10即为上述根据本发明第一方面实施例的空调室内机100的开关门组件10。
外箱底板部件20的一侧敞开，面板部件30设在外箱底板部件20的敞开侧，面板部件30上设有出风口。开关门安装板11设于面板部件30的朝向外箱底板部件20的一侧，开关门12可移动地打开和关闭出风口，当开关门12打开出风口时，开关门12位于面板部件30的远离外箱底板部件20的一侧。
其中，开关门安装板11上的通风通道1141与该出风口对应设置，在打开状态时，开关门12打开通风通道1141和出风口，即在空调室内机100停机时可以关闭出风口，防止外部杂质进入到空调室内机100内部。在关闭状态时，开关门12打开出风口以及通风通道1141，从而空调室内机100可以正常工作，经由出风口排出经过处理的气流，以对室内环境进行调控。
由于根据本发明上述的开关门组件10具有上述优点，因此通过设置该开关门组件10，从而可以时空调室内机100具有相应的优点，即开关门12可以更加顺畅、稳定地打开和关闭出风口，开关门12运动平稳，噪音低，空调室内机100的使用寿命高。
可选地，面板部件30上可以设有多个出风口。空调室内机100可以包括多个风机，多个风机可以分别对应多个出风口设置。可选地，如图12所示，出风口可以是两个，第一出风口31处对应设有第一风机40，第二出风口32处可以对应设有第二风机50。其中开关门组件10对应设在第二出风口32处，以打开和关闭第二出风口32。
第一风机40包括由第一风轮51和第二风轮51构成的对旋风机，即第一风轮51的叶片的倾斜方向和第二风轮51的叶片的倾斜方向相反，第一风轮51和第二风轮51在空气流动的方向上互为导叶，降低(第一风轮51和第二风轮51在不同的转速的情况下)或消除(第一风轮51和第二风轮51在相同的转速的情况下)了气流切向的旋转速度(即由动压转化为静压)，提高了对旋风机对空气的做功效率，并且经过两个风轮51的气流均朝向出风口的方向流动，从而实现远距离送风的效果。需要说明的是，较之于单一的贯流风机、轴流风机或斜流风机，对旋风机中第一风轮51和第二风轮51不管是以不同的速度反向旋转还是相同的速度反向旋转，对旋风机均能够实现更远距离的送风。
其次，第一风轮51和第二风轮51在不同的转速的情况下，可以扩大冷风的输送范围。因为当一个风轮51以较高的转速转动且另外一个风轮51以较低的转速转动时，较高转速的风轮51起主导作用，基于单级轴流或斜流风机的叶片气流出口角度设计偏离旋转轴方向，使得轴流风轮51或斜流风轮51本身具有散风效果，因此，由第一出风口31流出的冷风的角度范围较大，从而实现广角送风。另外，同样基于轴流风轮51或斜流风轮51本身具有散风效果，可根据需要来调整第一风轮51和第二风轮51的转速， 使其差速旋转，从而实现柔风感或无风感送风，避免了冷风由第一出风口31流出后直吹用户从而给用户造成不良的体验。因此，本实用新型实施例的空调室内机100无需使用带微孔的导风板即可实现柔风感或无风感送风，风量损失少。需要说明的是，为了实现广角送风和无风感送风，可使得其中一个风轮51对应的电机131不工作，另一个风轮51仍朝第一出风口31一侧正向送风。另外，为了实现广角送风和无风感送风，也可使得其中一个风轮51向面板组件内侧反向送风，另一个风轮51仍正向送风。其中，“正向送风”为在风轮51的作用下气流从第一出风口31吹出，“反向送风”为气流往面板组件的内侧吹入。
可选地，如图13和图14所示，空调室内机100还包括电机保护件53，第二风机50设于开关门组件10的远离面板部件30的一侧，第二风机50包括风轮51和驱动电机52，风轮51设于外箱底板部件20和面板部件30之间且用于朝向出风口送风，驱动电机52用于驱动风轮51转动，电机保护件53罩设在驱动电机52的外部设置，且电机保护件53的朝向开关门组件10的一侧敞开，密封罩14的至少一部分容纳在电机保护件53内部。由此可以进一步提高产品的结构紧凑性。
可选地，电机保护件53罩和密封罩14之间可以彼此接触，例如电机保护件53罩的前端可以与密封罩14的后端面接触，由此电机保护件53罩可以对此密封罩14产生抵压力，进而可以提高密封罩14的安装稳定性。
