具体实施方式
本发明实施例首先提供了一种壁挂式空调室内机，图1是根据本发明一个实施例的壁挂式空调室内机的示意图；图2是根据本发明一个实施例的壁挂式空调室内机的分解图；图3是图1所示的A区域的局部放大图。
如图1至图3所示，本发明实施例的空调室内机包括壳体100、设置于壳体100中的内机换热器(未图示)、左右两个贯流风扇200、左右两个导风装置、人体检测装置400以及主控装置300。其中，壁挂式空调室内机可通过管路与室外机连接，采用蒸汽压缩制冷循环系统实现对室内环境的制冷、制热或除湿，具体原理为本领域技术人员所悉知的，无需在此介绍。如图1、2所示，两个贯流风扇200沿室内机横向且同轴地设置于室内机内部的左右两侧。每个贯流风扇200对应一个出风口411，也就是说室内机左侧贯流风扇200向由左侧的出风口送风，右侧贯流风扇200向由右侧的出风口送风。每个导风装置分别设置于一个出风口处，用于调整对应的贯流风扇200的送风方向。在本实施中，每个导风装置包括：导风板110和多片摆叶120。导风板110设置于出风口处，且绕室内机横向的一条转轴转动，用于调整出风口的竖向出风方向；摆叶120横向排列于出风口内侧，每片摆叶120可沿室内机横向左右摆动，以调节出风口的横向出风方向。
如图3所示，人体检测装置400设置于两个出风口之间，也就是人体检测装置400设置于室内机的正中间，能够360°无死角地检测到室内所有人体的位置。上述人体检测装置400包括红外扫描仪，可以利用热感应技术检测人体位于室内的具体位置。人体检测装置400配置成每间隔预设时间，获取室内人体位置信息。上述预设时间可以为10至30秒。
指令接收装置500用于接收用户发出的控制指令。用户可以通过使用空调遥控器或者室内机上的按键向空调发送控制指令，上述控制指令可以包 括：制冷、制热、直吹、避让、睡眠等各种指令。
主控装置300与人体检测装置400和指令接收装置500连接，并接收人体位置信息和用户发出的控制指令。主控装置300配置成预先将室内划分为多个送风区域。主控装置300将室内机的横向出风角度范围划分为多个子角度范围，按照多个子角度范围划分为多个送风区域。例如在本实施例中，室内机的横向出风角度范围为120°，主控装置300首先将上述出风角度范围平均分成5个子角度范围(如图4中所示A-E，5个角度范围)，每个子角度范围为24°。主控装置300再按照上述多个子角度范围对应的室内地面区域，将室内划分为5个送风区域。上述人体检测装置400还可以按照划分的多个子角度范围，对多个送风区域逐一进行扫描检测，检测每个送风区域是否存在人体，并得到室内人体位置信息。主控装置300根据人体位置信息，确定人体所在的至少一个目标送风区域，例如人体检测装置400检测到B、C区域存在用户，则确定B、C区域为目标送风区域。
主控装置300根据用户发出的控制指令，确定空调室内机的运行模式。上述运行模式主要包括：跟随模式和避让模式。根据确定的至少一个目标送风区域以及空调室内机的运行模式，设定两个导风装置的运行方式。具体地，在空调室内机是否运行于跟随模式情况下，控制导风装置以左右扫风的方式向多个送风区域中的至少一个目标送风区域送风，也就是室内机向存在人体的送风区域送风，实现室内机朝向用户送风。在空调室内机运行于避让模式情况下，控制导风装置以左右扫风的方式向多个送风区域中的非目标送风区域送风，实现室内机避开用户送风。在送风过程，主控装置300通过控制导风装置中的摆叶120的摆动角度，控制室内机向预定的区域送风。
另外，在本实施例中，主控装置300还将室内地面划分为两个区间，即左区间和右区间。左侧和右侧的贯流风扇200分别向室内的左区间和右区间送风，即左右区间分别代表左右两个贯流风扇200所能达到的送风范围。上述左区间和右区间均可以包含多个送风区域。主控装置300控制左侧的导风装置对左区间内的目标送风区域送风或非目标送风区域送风；控制右侧的导风装置对右区间内的目标送风区域送风或非目标送风区域送风。本实施例的左贯流风扇200向左区间送风，右贯流风扇200向右区间送风，两侧的贯流风机200不会互相干扰，而且两个贯流风扇200同时向两侧方向送风，相对于现有的单一贯流风扇200，出风范围更广。
以下对本实施例的空调室内机的送风运行方式进行举例说明。在本实施例中，室内被划分为5个送风区域(即图4中A-E，5个区域)，左区间包括A、B、C三个送风区域，即左贯流风扇200可以向上述三个送风区域送风。右区间包括C、D、E三个送风区域，左右两个贯流风扇200均可以朝向C区域送风。当人体检测装置400检测到A、B、D三个区域存在人体，且用户选择跟随模式时，控制左侧风扇的导风装置的摆叶120在A、B两个送风区域对应的角度范围内反复摆动，以实现左侧的贯流风扇200在A、B两个送风区域内循环扫风。同时，控制右侧风扇的导风装置的摆叶120在D区域对应的角度范围内反复摆动，以实现左侧的贯流风扇200在D送风区域内循环扫风。当用户选择避让模式时，控制左侧风扇的导风装置的摆叶120在C区域对应的角度范围内反复摆动，以实现左侧的贯流风扇200在C区域内扫风。同时，控制右侧风扇的导风装置的摆叶120在C、E两个送风区域对应的角度范围内反复摆动，以实现右侧的贯流风扇200在C、E送风区域内循环扫风。
人体检测装置400还配置成检测人体表面温度。上述人体检测装置400通过热感应技术检测人体的表面温度。主控装置300根据人体表面温度设定每个贯流风扇200的转速。例如：在空调制冷时，检测到人体表面温度较高，也就是用户感到炎热，此时控制贯流风扇200以高速运转，以尽快降低用户表面温度。当检测到人体表面温度较低，也就是用户感到寒冷，此时控制贯流风扇200以低速运转，以避免用户感觉太冷。
本发明还提供了一种空调室内机的控制方法，图6是根据本发明一个实施例的壁挂式空调室内机的控制方法的示意图，该方法一般性的包括以下步骤：
步骤S602，预先将室内划分为多个送风区域。在本实施例中，先将室内机的横向出风角度范围划分为多个子角度范围，按照多个子角度范围划分为多个送风区域。例如室内机的横向出风角度范围为120°，主控装置300首先将上述出风角度范围平均分成5个子角度范围(如图4中所示A-E，5个角度范围)，每个子角度范围为24°。主控装置300再按照上述多个子角度范围对应的室内地面区域，将室内划分为多个送风区域。
步骤S604，检测室内人体位置，确定人体所在的至少一个目标送风区域。对多个送风区域逐一进行扫描检测，检测每个送风区域是否存在人体， 并得到室内人体位置信息。
步骤S606，接收用户发出的控制指令，确定空调室内机的运行模式。用户可以通过使用空调遥控器或者室内机上的按键向空调发送控制指令，上述控制指令可以包括：制冷、制热、直吹、避让、睡眠等各种指令。
步骤S608，根据确定的至少一个目标送风区域以及空调室内机的运行模式，设定两个导风装置的运行方式。本实施例的方法根据用户的具体位置以及用户选择的室内机的运行模式设定贯流风扇200的出风方式，室内机能够根据用户需要以及室内机的实际情况设定最佳的出风方式，使得室内机送风更加智能，提高了用户使用体验。
图7是根据本发明一个实施例的壁挂式空调室内机的控制方法的流程图，该方法依次执行以下步骤：
步骤S702，预先将室内划分为多个送风区域。
步骤S704，检测室内人体位置，确定人体所在的至少一个目标送风区域。
步骤S706，接收用户发出的控制指令，确定空调室内机的运行模式。
步骤S708，判断空调室内机是否运行于跟随模式。所谓跟随模式是指，室内机出风朝向用户。
步骤S710，若步骤S708的判断结果为是，控制导风装置以左右扫风的方式对至少一个目标送风区域送风。主控模块设定导风装置中的摆叶120的左右摆动角度，使得贯流风扇200只朝向目标送风区域(即用户存在的区域)送风。调节左侧的导风装置使得左侧的贯流风扇200对左区间内的目标送风区域送风或非目标送风区域送风；调节右侧的导风装置使得右侧的贯流风扇200对右区间内的目标送风区域送风或非目标送风区域送风。
步骤S712，若步骤S708的判断结果为否，继续判断空调室内机是否运行于避让模式。所谓跟随模式是指，室内机出风方向避开用户。
步骤S714，若步骤S712的判断结果为是，控制导风装置以左右扫风的方式对多个送风区域中的非目标送风区域送风。主控模块设定导风装置中的摆叶120的左右摆动角度，使得贯流风扇200朝向非目标送风区域(即用户不在的区域)送风。且左侧的贯流风扇200只向左区间送风，右侧的贯流风扇200向右区间送风。
步骤S716，若步骤S712的判断结果为否，控制导风装置根据用户指令 运行。若用户发出“跟随”或“避让”模式以外的指令，则根据用户的实际指令运行。例如：用户指示空调进入全空间扫风模式，则控制导风装置在整个室内机横向出风角度范围内往复摆动。
步骤S718，检测人体表面温度。利用红外感测技术检测室内人体的表面温度，获得用户的冷热状态。
步骤S720，根据人体表面温度设定每个贯流风扇200的转速，以提高用户的舒适度。例如：在空调制冷时，检测到人体表面温度较高，也就是用户感到炎热，此时控制贯流风扇200以高速运转，以尽快降低用户表面温度。当检测到人体表面温度较低，也就是用户感到寒冷，此时控制贯流风扇200以低速运转，以避免用户感觉太冷。
采用本实施例的控制方法，对室内人体进行检测，根据各个送风区域的扫描结果，判断人所在位置。再根据用户设定室内机“跟随”/“避让”模式，使得出风方向朝向/避开用户。用户可以根据实际情况设定室内机出风模式，例如：在空调制冷时，若用户感觉到温度较低，则可以选择避让模式，以防止空调直吹，引起空调病；又例如在空调制热时，则可以选择跟随模式，以使得用户始终处于温暖的空气环境内，提高用户舒适度。本实施例的控制方法使得室内机出风方式多样化，提高了用户体验。
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。
