下面详细描述本公开的实施例，参考附图描述的实施例是示例性的，下面详细描述本公开的实施例。
下面参考图1-图23描述根据本公开实施例的空调室内机100，空调室内机100可以为壁挂式空调室内机。在本申请下面的描述中，以空调室内机100为壁挂式空调室内机为例进行说明。
如图1-图8所示，根据本公开实施例的空调室内机100包括壳体1、内导风板2、外导风板3和外驱动装置4。
如图2和图3所示，壳体1包括具有第一容纳空间的第一容纳部11和具有第二容纳空间的第二容纳部12。第一容纳部11具有出风口111(如图4所示)，第二容纳空间位于第一容纳空间的前侧，内导风板2可枢转地设在第一容纳空间内，外导风板3可枢转地设在第二容纳空间内，两个外驱动装置4分别设在壳体1的左侧和右侧以驱动外导风板3在第二关闭位置和第二打开位置之间可转动。
如图3所示，具有第一容纳空间的第一容纳部11和具有第二容纳空间的第二容纳部12位于壳体1的前侧，且第二容纳空间位于第一容纳空间的前侧。内导风板2可转动地设置在第一容纳部11内，用于控制出风口111的打开和关闭，外导风板3可转动地设置在第二容纳部12内，从而减小了外导风板3与内导风板2的尺寸差异。内导风板2位于外导风板3的后侧，当内导风板2和外导风板3均处于关闭状态时，外导风板3遮挡内导风板2，这时外导风板3的前侧表面与壳体1前侧表面平齐，有效地保证了空调室内机100外观的美观性。这里需要说明的是，在本说明书的描述中，当用户面对空调室内机100时，将朝向用户的方向称为“前”，反之远离用户的方向称为“后”，因此，第二容纳空间位于第一容纳空间的前侧，当内导风板2与外导风板3均处于关闭的状态时，外导风板3位于内导风板2的前侧。
根据本公开实施例的空调室内机100，壳体1具有第一容纳部11和第二容纳部12，内导风板2在第一容纳部11内转动，外导风板3在第二容纳部12内转动，内导风板2与外导风板3关闭时，内导风板2位于外导风板3的后侧且由外导风板3遮挡。由此，减小了外导风板3与内导风板2的尺寸差异，保证了空调室内机100的壳体1的美观性。
根据本公开的一些实施例，壳体1包括外罩13和分别设在外罩13左侧和右侧的左侧罩131和右侧罩132。如图5所示，其中第一容纳部11设在外罩13上。通过将第一容纳部11位于外罩13的前部，有效地保证了内导风板2的安装空间，便于加长内导风板2的长度，减小内导风板2与外导风板3的尺寸差异，提高导风效果。第二容纳部12由外罩13、左侧罩131和右侧罩132共同构成，由此，保证了外导风板3的安装空间。
在一些可选的实施例中，结合图3，壳体1还可以包括面板15和底座16，面板15位于外罩13的一侧(例如，图3的右侧)，底座16固定于外罩13的下端。
如图12和图13所示，根据本公开的一些实施例，空调室内机100还包括两个外驱动装置4，两个外驱动装置4分别设在壳体1的左侧和右侧以驱动外导风板3在第二关闭位置和第二打开位置之间可转动。在一些具体的示例中，如图14和图15所示，每个外驱动装置4均包括电机41、连杆42和旋转臂43，电机41安装在外罩13的侧部，连杆42与电机41连接且被电机41驱动转动，旋转臂43的一端可枢转地连接至连杆42，且旋转臂43的另一端可枢转地连接至外导风板3。
在一些可选的实施例中，参照图14，外驱动装置4还包括传动组件45，传动组件45设在电机41和连杆42之间，传动组件45包括多个彼此啮合的齿轮以调整电机41输出至连杆42的驱动力。
例如，在图12-图15的示例中，每个外驱动装置4还包括连杆壳体44，电机41与传动组件45连接，传动组件45与连杆42连接，连杆42与旋转臂43旋转连接，连杆42与旋转臂43设置在连 杆壳体44内，旋转臂43的另一端伸出连杆壳体44与外导风板3可枢转地连接。电机41也可以与直接与连杆42连接，但是需要较大的电机驱动力，通过电机41与传动组件45的连接，传动组件45与连杆42连接可以放大电机驱动力，从而降低电机41成本。
在一些可选的的实施例中，参照图15，传动组件45包括第一齿轮451、第二齿轮452以及彼此啮合的第三齿轮453和第四齿轮454，第一齿轮451套设在电机41的电机轴上，第二齿轮452连接至连杆42的旋转轴以带动连杆42旋转，第三齿轮453啮合于第一齿轮451且第四齿轮454啮合在第二齿轮452上，有效地保证传动组件45的传动效率。
进一步可选地，第一齿轮451、第二齿轮452、第三齿轮453、第四齿轮454的外径D1、D2、D3、D4的大小满足：D4＜D1＜D2＜D3。如此设置，易于放大外驱动装置4的驱动力，降低电机41成本。当然，本公开并不限于此。传动组件45还可以根据具体设计以确定采用的齿轮个数和外径比例。
在本公开一些进一步的实施例中，参照图13并结合图16-图19，外导风板3的内表面具有滑动部35，如图17所示，外导风板3的内表面左右两端均设有滑动部35。滑动部35上可滑动地设有滑动件36，滑动件36具有滑动杆361，旋转臂43的上述另一端具有插孔431，滑动杆361可旋转地插入插孔431内，有效地保证了滑动杆361和旋转臂43的灵活性，以及旋转臂43在外导风板3打开时起到支撑的作用。
在一些具体的实施例中，如图17-图20所示，滑动件36呈板状，但不限于此。滑动件36的朝向外导风板3的一侧表面上具有定位槽362，滑动部35上具有定位凸起351，参照图17，滑动部35上设有两个定位凸起351，两个定位凸起351上下相对，通过定位凸起351在定位槽362内的滑动以实现滑动件36在滑动部35上的滑动。由此，滑动件36带动外导风板3转动，加工简单。
如图19所示，滑动件36的远离导风板的一侧具有定位部363，即滑动件36朝向空调室内机100内部的一侧设有定位部363，定位部363的延伸轴线平行于滑动件36，定位槽362由定位部363与滑动件36限定构成。由此，有效地保证滑动件36固定的牢靠性，同时节省材料，降低成本。
进一步地，滑动件36的远离导风板的一侧具有两个限位条364，两个限位条364垂直于定位部363延伸轴线，两个限位条364设在定位槽362两端以对定位凸起351在定位槽362内的位置进行限位。
在一些可选的实施例中，如图19所示，定位部363包括延伸柱3631和两个延伸片3632，延伸柱3631的横截面成大体圆形，延伸柱3631的一端与滑动件36平齐，即图19中延伸柱3631的左端与滑动件36的左端平齐，滑动杆361同轴地连接至延伸柱3631的一端，两个延伸片3632彼此平行地设在延伸柱3631的两侧且从滑动件36向远离导风板的方向延伸出，也就是说，两个延伸片3632朝向空调室内机100的内部的方向延伸，且两个延伸片3632之间的距离小于延伸柱3631的直径，避免延伸柱3631出现脱落，保证了延伸柱3631固定的牢靠性，定位槽362由延伸片3632和滑动件36之间限定出。
参照图17和图19，进行外导风板3与外驱动装置4安装时，滑动件36朝向外导风板3的中 心移动，待滑动杆361与外导风板3侧板上的孔对准时，再将滑动件36推向连杆42，使得连杆42与外导风板3铰接在一起。拆卸时，用力将滑动件36向远离连杆42的方向拨动即可。具体地，如图19所示，滑动件36背面设有定位部363，定位部363与滑动件36的一侧面形成有定位槽362，定位槽362的左右设有限位条364，对应外导风板3后侧板上的滑动部35的上下边沿设有定位凸起351，安装时，定位凸部位于定位槽362内，通过滑动件36在滑动部35内的左右滑动，实现旋转臂43与外导风板3的连接。
在一些可选的实施例中，滑动杆361和延伸柱3631为金属件，滑动件36和延伸片3632为塑料件，滑动杆361、延伸柱3631、滑动件36和延伸片3632一体注塑成型。由此，保证了滑动杆361和延伸柱3631的强度，易于安装，加工简单。
如图5所示，根据本公开的一些实施例，左侧罩131和右侧罩132的前侧分别具有左凹入部1311和右凹入部1321，左侧罩131和右侧罩132装配至外罩13后，左凹入部1311、右凹入部1321、外罩13共同限定出第二容纳部12，左侧罩131和右侧罩132的前侧还分别具有外板安装柱1312，外导风板3的下端可枢转地与外板安装柱1312连接。参照图4-图7，左侧罩131和右侧罩132固定在外罩13左右两端，左侧罩131和右侧罩132的前侧还分别具有外板安装柱1312，外导风板的下端可枢转地与外板安装柱1312连接。外导风板3的下端与外板安装柱1312连接可枢转地固定于第二容纳空间，保证了外导风板3的安装空间，易于安装。
根据本公开的一些具体实施例，如图3和图21所示，外导风板3内部中空且包括彼此连接的外板后面板38和外板前面板37，外板后面板38具有向外板前面板37凸出的弧形板，从而形成气流康达效应，提升空调室内机100的送风距离，同时，便于外导风板3打开时，出风口111的风向上吹，然后自由落下，形成淋浴式吹风，提高用户的舒适度。
在一些可选的实施例中，如图8所示，外板后面板38上设有沿左右方向延伸的多条平行的外板花纹39，保证外导风板3的强度同时，减轻外导风板3的重量，实现外导风板3的轻量化。
根据本公开的实施例的空调室内机100，如图3所示，空调室内机100安装后，外导风板3的安装部上端距离墙壁的尺寸大于外导风板3的安装部下端距离墙壁的尺寸，如此便于空调室内机100工作时，将出风口111的风往远离墙壁的方向吹，减少风流经外导风板3安装部与外罩13之间的缝隙，从而减少外导风板3前侧面处的凝露。
在本公开一些进一步的实施例中，参照图3和图8，内导风板2内部中空且包括彼此连接的内板后面板22和内板前面板21，内板前面板21被构造成向后凸出的弧形面板，且内板后面板22和内板前面板21的弧度不同，内板后面板22的弧度大于内板前面板21的弧度，有效地保证内导风板2的强度。
在一些可选的实施例中，如图3所示，内导风板2的上端被构造成弧形端部，有效地保证内导风板2可枢转地固定在第一容纳部11，内板后面板22的延伸长度小于内板前面板21的延伸长度，且内板前面板21的下端向后弯折并包覆内板后面板22的下端，内板前面板21的下端的弯折角度满足30-80度(包括端点值)，可选地大约60度，但不限于此。由此，便于内板后面板22和内板 前面板21一体成型，加工简单。
在一些可选的实施例中，内板后面板22和内板前面板21的至少一个上设有沿左右方向延伸的多条平行的内板花纹23。在图3和图8所示的示例中，内板后面板22的后侧表面设有内板花纹23，内板前面板21的前侧表面设有内板花纹23，由此，便于实现对气流的导向作用，而且还减轻了内导风板2的重量，实现零件的轻量化。当然，也可以仅在内板后面板22或内板前面板21上设置内板花纹23。
在本公开一些进一步的实施例中，内导风板2位于第一关闭位置时的上端的厚度大于其下端的厚度。参照图3和图8，内导风板2处于关闭时，内导风板2上端的厚度大于其下端的厚度，有效地保证内导风板2的强度，避免内导风板2转动过程中出现断裂情况。这里需要说明的是，内导风板2关闭时朝向空调室内机100外部且位置相对高的一端称为“上端”(即枢转端)，朝向空调室内机100内部且位置相对低的一端称为“下端”(即自由端)。
如图4所示，第一容纳部11包括第一弧面板112、第一左侧板113和第一右侧板114，第一弧面板112位于壳体1的一侧，且第一弧面板112从下到上逐渐向后倾斜，保证第一弧面板112的弧形与内导风板2一致，提高内导风板2关闭时与第一弧面板112的契合度，减小内导风板2与外罩13的间隙。第一左侧板113和第一右侧分别位于第一弧面板112左右两侧，三者限定出第一容纳空间，内导风板2可枢转地位于第一容纳空间内。
在本公开一些进一步的实施例中，如图4所示，第一左侧板113和第二右侧板上相对地设有第一内板安装柱1131和第二内板安装柱1141，内导风板2的上端两侧分别可枢转地连接于第一内板安装柱1131和第二内板安装柱1141。可选地，如图5示出的示例中，可以在第一左侧板113和第二左侧板上分别具有内板安装孔，第一内板安装柱1131和第二内板安装柱1141的一端插入并固定在内板安装孔内而另一端外露，与内导风板2枢转连接，有效地保证内导风板2固定的牢靠性。
根据本公开的一些实施例，如图5所示，壳体1还包括内板安装板14，内板安装板14设在外罩13上，且后端与第一弧面板112的顶部相连。内导风板2安装于内板安装板14上，内板安装板14的前部下端向下延伸出卡扣，外罩13顶部具有卡槽，卡扣与卡槽配合将内板安装板14安装在外罩13的顶部。内板安装板14的前表面从下到上向前倾斜，限定出第一容纳部11的顶部区域。由此，内板安装板14和外罩13可以独立注塑成型，易于内板安装板14和外罩13出模，制造装配方便。
在本公开一些进一步的实施例中，外板安装柱1312具有固定孔，外导风板3的至少一端具有活动插销组件31，也就是说，外导风板3的一端可以设有活动插销组件31，或者外导风板3的两端均设有活动插销组件31。活动插销组件31适于与固定孔配合且与相应的左侧罩131和/或右侧罩132锁定。如图9所示，外导风板3的左端设有活动插销组件31，外导风板3安装时，活动插销组件31与左侧罩131的外板安装柱1312配合使用，有效地保证外导风板3固定的牢靠性，以及便于外导风板3的安装和拆卸。
在本公开一些进一步的实施例中，如图9和图10所示，外导风板3的左右两端均垂直地延伸 出侧壁32，而如图10所示，相应一侧的侧壁32上具有第一固定孔321和第二固定孔322，外导风板3的邻近侧壁32处还设有挡板33，挡板33具有第三固定孔331。具体而言，参照图9和图10，外导风板3的左侧的侧壁32上设有第一固定孔321和第二固定孔322，挡板33位于外导风板3左侧的侧壁32的右侧，挡板33的远离外导风板3的一侧设有第三固定孔331。如图9-图11所示，活动插销组件31位于侧壁32和挡板33之间，且包括第一固定柱311、第二固定柱312、插销柱313和弹簧314，第一固定柱311适于插入第一固定孔321，第二固定柱312与第一固定柱311平行且通过连接柱相连，第二固定柱312适于穿过第二固定孔322与固定孔配合，插销柱313设在连接柱的上部且远离第一固定柱311延伸，插销柱313适于穿过第三固定孔331，弹簧314套设在插销柱313上。由此，有效地保证活动插销组件31固定的牢靠性，通过挡板33上的第三固定孔331对活动插销组件31的弹簧314起到限位作用，保证活动插销组件31在弹簧314的作用力下进行伸缩。
安装时，活动插销组件31安装到外导风板3的左侧侧壁32和挡板33之间且将弹簧314的两端止抵在侧壁32和挡板33之间，此时插销柱313的自由端穿过第三固定孔331，弹簧314作用下将第一固定柱311和第二固定柱312分别推入第一固定孔321和第二固定孔322中，第二固定柱312适于与外板安装柱1312的固定孔配合。
在一些可选的实施例中，外导风板3的其中一侧设有活动插销组件31，且另一侧具有第三固定柱34，第三固定柱34适于与相应侧的固定孔配合。参照图9，外导风板3的左侧设有活动插销组件31，右侧设有第三固定柱34，第三固定柱34与右侧罩132的外板安装柱1312上的固定孔配合，便于外导风板3的安装和拆卸。
当安装外导风板3时，外导风板3右侧的第三固定柱34对准右侧罩132的外板安装柱1312上的固定孔，将第三固定柱34插入固定孔内，之后进行外导风板3左侧的活动插销组件31的固定，按动第一固定柱311，弹簧314被压缩，第二固定柱312和插销柱313朝向外导风板3的右侧移动，此时，第二固定柱312隐藏于外导风板侧壁32的第二固定孔322内，将外导风板3对准左侧罩131的外板安装柱1312，松开第一固定柱311，在弹簧力的作用下，第二固定柱312和插销柱313朝向外导风板3的左侧移动，第二固定柱312露出第二固定孔322，插入外板安装柱1312内，完成外导风板3的安装。
根据本公开的实施例的空调室内机100，如图22所示，空调室内机100制冷时，内导风板2摆动到最上方，外导风板3摆动送风。如图23所示，空调室内机100制热时，外导风板3摆动到最上方，内导风板2摆动送风。由此，实现空调室内机100不管是制冷还是制热，用户都能体验沐浴式吹风，提高用户的舒适感。
