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。
附图说明
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解，这些附图未必是按比例绘制的。附图中：
图1是根据本发明一个实施例的空调器室内机的示意图；
图2是根据本发明一个实施例的空调器室内机的示意性框图；
图3是根据本发明一个实施例的空调器室内机的控制方法的示意图；
图4是根据本发明一个实施例的空调器室内机的控制流程图；
图5是根据本发明一个实施例的空调器室内机的使用场景示意图；
图6是根据本发明另一个实施例的空调器室内机的使用场景示意图。
具体实施方式
图1是根据本发明一个实施例的空调器室内机10的示意图，图2是根据本发明一个实施例的空调器室内机10的示意性框图。
空调器室内机10和室外机可以通过压缩制冷系统进行有效的配合运转，以完成空调器的制冷和制热循环，从而实现对室内环境空气的冷热调节。
空调器室内机10可以为立式柜机，例如方形柜机或者圆形柜机，也可以为壁挂机，但不限于此。
本实施例以壁挂机进行示例，本领域技术人员在了解本实施例的基础上应当完全有能力针对其他室内机机型进行拓展，故，在此不再一一举例。
空调器室内机10一般性地可包括：激光探测装置200、处理器和存储器，还可以进一步地包括壳体500、导风机构、送风机构和换热器。
其中，壳体500具有回风口、出风口501、以及位于回风口和出风口501之间的空气处理通道。壳体500大致可以呈长方体形状、圆柱体形状或者其他任意形状。本实施例中，壳体500大致可以为长方体形状。
周围环境的空气可以通过回风口进入壳体500内部。空调器室内机10将壳体500内部的气流通过出风口501吹送至周围环境。
回风口可以设置于壳体500的顶部、背部、侧部或者前部。出风口501可以设置于壳 体500的底部、前部或侧部。本实施例中，回风口可以设置于壳体500的顶板上，出风口501可以设置于壳体500的前面板与底板相接的部位。
激光探测装置200可以为LiADR激光雷达传感器。激光探测装置200可以设置于壳体500上，例如，可以设置于出风口501的几何中心处，也可以设置于壳体500的前面板上并且与出风口501邻近设置，使得激光探测装置200发射的激光探测信号可以大致视为从出风口501发出。
激光探测装置200可以向周围环境中快速发射激光探测信号，例如，激光脉冲(通常最高可达每秒150000次脉冲)，用于检测周围环境中目标用户和障碍物的相关信息，例如，目标用户的身体轮廓信息、目标用户的位置、障碍物的位置、周围环境中的物体模型等信息中的一个或多个。障碍物可以指周围环境中的沙发、橱柜、墙体等物体中的一个或多个，是相对于目标用户而言的。激光探测装置200可以根据反射信号中的呼吸、心跳、和/或脉搏等生物特征识别出周围环境中的目标用户。激光探测信号中的激光波长可以为900～1500nm，分辨率准确率高，居室环境中灰尘烟雾较少，激光探测信号受干扰较小，可以满足居室环境的使用要求。
由于房间布局及家居的摆放位置各异，在日常使用过程中，会出现空调器室内机10与目标用户之间被沙发、壁橱等物体阻隔的情况，阻隔目标用户与空调器室内机10的物体即为障碍物。障碍物将周围环境空间一分为二，即与空调器室内机同为一侧送风不受影响的空间，以及位于障碍物后方且空调器室内机10的送风气流达不到的空间。比如，在制冷模式下，送风气流由上至下吹送时，安装在空调器室内机10正对面上方的壁橱会阻隔壁橱后有降温需求的目标用户，或者在制热模式下，送风气流由下至上吹送至，摆放在空调器室内机斜下方的沙发会阻隔沙发斜后方有暖足需求的用户等等。
激光探测信号到达周围环境中的物体或目标用户后反射回激光探测装置200。激光探测装置200通过对反射信号进行分析，可以精确计算确定激光探测装置200到周围环境中的物体或目标用户之间的距离，并且能够探测周围环境中的物体或目标用户的准确尺寸或轮廓，从而对周围环境内所有物体和/或目标用户进行精确定位。例如，激光探测装置200通过测量激光探测信号从发射到返回的时间，精确计算确定激光探测装置200到障碍物之间的距离。利用激光探测装置200可以针对周围环境中的所有物体绘制出高分辨率地图，从而得到周围环境中的物体模型。
导风机构设置于出风口501处，其可以包括至少一块导风板，或者可以包括多个摆叶，用于调节空调器室内机10的出风方向。
送风机构设置于壳体500内，并位于空气处理通道中，其可以包括送风风机，例如，贯流风机，离心风机或者离子风发生装置。送风风机配置成促使室内环境空气从回风口流入空气处理通道形成处理气流，处理气流经处理后从出风口501吹送出。“经处理”中的“处理”可以指对处理气流的温度、湿度、含氧量、含菌量等参数中的一个或多个进行处理。
换热器设置于空气处理通道中，配置成与流经其的处理气流换热。换热器的类型可以根据实际使用需求进行选择，例如，可以为管翅式换热器，板式换热器或者其他任意类型的换热器。
存储器420以及处理器410可以形成控制装置。控制装置可以设置于壳体500内。在另一些可选的实施例中，控制装置也可以设置于壳体500外，并与家电控制系统集成设置。
其中，存储器420内存储有控制程序421，控制程序421被处理器410执行时用于实现以下任一实施例的空调器室内机10的控制方法。处理器410可以是一个中央处理单元(CPU)，或者为数字处理单元(DSP)等等。存储器420用于存储处理器410执行的程序。存储器420可以是能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何介质，但不限于此。存储器420也可以是各种存储器420的组合。由于控制程序421被处理器410执行时实现下述方法实施例的各个过程，且能达到相同的技术效果，为避免重复，这里不再赘述。
图3是根据本发明一个实施例的空调器室内机10的控制方法的示意图。该空调器室内机10的控制方法一般性地可以包括：
步骤S302，驱动激光探测装置200向空调器室内机10周围环境中发射激光探测信号。
例如，空调器室内机10可以预设有风吹人模式，在该模式下，空调器室内机10的送风气流直接吹向目标用户，且风随人动。空调器室内机10可以在接收到风吹人模式的启动指令后驱动激光探测装置200向周围环境中发射激光探测信号。
在驱动激光探测装置200向空调器室内机10周围环境中发射激光探测信号的步骤中，激光探测信号可以从空调器室内机10的出风口501朝向目标用户发射，使得激光探测信号在传播过程中可以经过目标用户的全部身体部位。例如，激光探测信号的发射点可以为出风口501的几何中心。激光探测信号的发射方向是指发射点与目标用户之间连线所在的方向。
在另一些可选的实施例中，激光探测信号的发射点可以为壳体500的靠近出风口501几何中心的位置，例如，出风口501的上方或下方。由于空调器室内机10与目标用户之间的距离远大于激光探测信号的发射点与出风口501几何中心之间的距离，故，激光探测信号的发射方向可以视为从出风口501朝向目标用户发射。
步骤S304，获取激光探测信号的反射信号。由于激光探测信号视为从出风口501朝向目标用户发射，激光探测信号的反射信号中包含目标用户的身体轮廓信息、激光探测信号的发射方向上所存在的障碍物的位置信息等信息。
步骤S306，根据反射信号判断周围环境中是否发生遮挡事件，遮挡事件为周围环境中目标用户的至少部分身体部位因受障碍物遮挡而形成无风感身体部位的事件。若目标用户的全部身体部位均未被障碍物遮挡，则确定周围环境中未发生遮挡事件。其中，“遮挡”是指障碍物位于激光探测信号的发射方向上，且位于出风口501与目标用户之间，当空调器室内机10朝向目标用户吹送送风气流时，障碍物会遮挡送风气流，导致送风气流无法 直接吹送至目标用户的部分身体部位。目标用户的未受障碍物遮挡的身体部位为有风感身体部位。
根据反射信号判断周围环境中是否发生遮挡事件的步骤，包括：根据反射信号获取目标用户的身体轮廓信息，身体轮廓信息标示有激光探测信号经目标用户的各个身体部位反射的反射信号的强度，根据身体轮廓信息判断周围环境中是否发生遮挡事件。
若目标用户的部分身体部位因被障碍物遮挡而形成无风感身体部位，身体轮廓信息所标示的该无风感身体部位的反射信号的强度较弱，并且弱于身体轮廓信息所标示的有风感身体部位的反射信号的强度。
根据身体轮廓信息判断周围环境中是否发生遮挡事件的步骤包括：判断身体轮廓信息所标示的激光探测信号经目标用户的各个身体部位反射后的反射信号的强度是否一致，若否，则确定周围环境中发生遮挡事件，若是，则确定周围环境中未发生遮挡事件。
其中，在判断身体轮廓信息所标示的激光探测信号经目标用户的各个身体部位反射后的反射信号的强度是否一致的步骤中，可以先提取身体轮廓信息所标示的激光探测信号经目标用户的各个身体部位反射后的反射信号强度的最大值和最小值，若最大值和最小值之间的差值大于设定差值阈值，则确定身体轮廓信息所标示的激光探测信号经目标用户的各个身体部位反射后的反射信号的强度不一致。
在另一些可选的实施例中，可以对周围环境中是否发生遮挡事件的判断方法进行变换。根据反射信号判断周围环境中是否发生遮挡事件的步骤还可以包括：根据反射信号分别获取目标用户的位置和障碍物的位置，根据目标用户的位置和障碍物的位置判断周围环境中是否发生遮挡事件。由于周围环境中存在多个物体，障碍物可以指激光探测信号在发射方向上传播时探测到的第一个障碍物。
其中，根据目标用户的位置和障碍物的位置判断周围环境中是否发生遮挡事件的步骤，包括：根据目标用户的位置获取目标用户相对于空调器室内机10的距离，记为第一距离，根据障碍物的位置获取障碍物相对于空调器室内机10的距离，记为第二距离，判断第一距离是否大于第二距离，若是，则确定周围环境中发生遮挡事件，若否，则确定周围环境中未发生遮挡事件。
周围环境中可以预设有空间直角坐标系，空调器室内机10出风口501的几何中心可以为空间直角坐标系的原点。目标用户的位置可以指目标用户在空间直角坐标系中的坐标，障碍物的位置可以指障碍物在空间立体坐标系中的坐标。目标用户相对于空调器室内机10的距离、以及障碍物相对于空调器室内机10的距离可以分别根据目标用户的位置、以及障碍物的位置计算得出。
在第一距离大于第二距离的情况下，在激光探测信号的发射方向上，障碍物位于目标用户与空调器室内机10之间。在第一距离小于第二距离的情况下，在激光探测信号的发射方向上，目标用户位于障碍物与空调器室内机10之间。
步骤S308，若确定出周围环境中发生遮挡事件，则获取空调器室内机10的运行状态 和遮挡事件的属性信息。运行状态可以包括调温模式，调温模式可以包括制冷模式和制热模式。遮挡事件的属性信息可以包括：目标用户的未被障碍物遮挡的有风感身体部位的位置、目标用户的无风感身体部位的面积、周围环境中障碍物的横向两侧的空隙的位置等信息中的一个或多个。
空调器室内机10可以针对激光探测信号的反射信号进行进一步分析，以确定遮挡事件的属性信息中的一个或多个。例如，可以根据身体轮廓信息进一步地确定目标用户的有风感身体部位的位置和无风感身体部位的面积。可以先根据反射信号的强弱来辨识有风感身体部位和无风感身体部位，进而确定有风感身体部位的位置。空调器室内机10可以对身体轮廓信息进行分析，绘制出目标用户的身体轮廓模型，根据身体轮廓模型可以计算无风感身体部位的面积。
周围环境中可能布置有多个物体，例如，沙发、橱柜、墙体等。当某一物体位于目标用户与出风口501之间时，则该物体成为障碍物。“横向”是相对于空调器室内机10的实际状态而言的，大致可以为水平方向，且平行于出风口501的横向延伸方向。障碍物的横向两侧的空隙是指位于障碍物横向两侧的不存在其他物体的空间。例如，若障碍物为沙发，则障碍物的横向两侧的空隙是指位于沙发的横向两侧的空隙。在一些可选的实施例中，在确定出周围环境中发生遮挡事件的情况下，可以驱动激光探测装置200向整个周围环境发射激光探测信号，并根据激光探测信号的反射信号建立整个周围环境的物体模型，物体模型中包含周围环境中所有物体(包括障碍物)的轮廓信息和位置信息。根据周围环境的物体模型，可以确定障碍物横向两侧的空隙。
步骤S310，根据空调器室内机10的运行状态和遮挡事件的属性信息调整空调器室内机10的出风方向和/或出风速度。在空调器室内机10未获取到运行状态或遮挡事件的属性信息的情况下，空调器室内机10不做任何调整。
本实施例中，在获取空调器室内机10的运行状态和遮挡事件的属性信息的步骤中，运行状态包括空调器室内机10的调温模式，属性信息包括目标用户的未被障碍物遮挡的有风感身体部位的位置。根据空调器室内机10的运行状态和遮挡事件的属性信息调整空调器室内机10的出风方向的步骤包括：判断空调器室内机10的调温模式是否为制冷模式，若是，将空调器室内机10的出风方向调整为朝向目标用户的有风感身体部位送风。
在一些进一步的实施例中，将空调器室内机10的出风方向调整为朝向目标用户的有风感身体部位送风的步骤包括：判断目标用户的有风感身体部位的位置是否为多个，若是，比较多个有风感身体部位所在位置的高度，得到最高值，将空调器室内机10的出风方向调整为朝向与最高值相对应的有风感身体部位送风。
若目标用户的有风感身体部位并非为连续的整体，则目标用户的有风感身体部位的位置为多个。
例如，若目标用户的头部和腹部及以下均为有风感身体部位，而胸部为无风感身体部位，则有风感身体部位的位置为两个。腹部及以下部位为连续的整体，可视为一个有风感 身体部位。且目标用户的头部的高度大于腹部及以下部位的高度，此时可以控制空调器室内机10朝向目标用户的头部送风。
由于冷空气密度较大，在制冷模式下，送风气流的温度较低，在有风感身体部位的位置有多个的情况下，将空调器室内机10的出风方向调整为朝向与最高值相对应的有风感身体部位送风，可以提高送风气流的降温效果。
在一些更进一步的实施例中，若目标用户的有风感身体部位的位置为一个，则直接控制空调器室内机10朝向该有风感身体部位送风。若未获取到目标用户的有风感身体部位的位置，则空调器室内机10不做任何调整。
在另一些更进一步的实施例中，在获取空调器室内机10的运行状态和遮挡事件的属性信息的步骤中，属性信息还包括目标用户的无风感身体部位的面积，且根据空调器室内机10的运行状态和遮挡事件的属性信息调整空调器室内机10的出风速度的步骤包括：判断目标用户的无风感身体部位的面积是否大于设定面积阈值，若是，将空调器室内机10的出风速度调整为设定出风速度，若否，则不调整空调器室内机10的出风速度。设定出风速度可以为空调器室内机10的最高风速。
在目标用户的无风感身体部位的面积大于设定面积阈值的情况下，将空调器室内机10的出风速度调整为设定出风速度，可以提高空调器室内机10的制冷效果，降低遮挡事件所导致的风感差、降温效果不明显等不利影响，提高目标用户的舒适度。
在另一些可选的实施例中，在获取空调器室内机10的运行状态和遮挡事件的属性信息的步骤中，属性信息还包括周围环境中障碍物的横向两侧的空隙的位置，且根据空调器室内机10的运行状态和遮挡事件的属性信息调整空调器室内机10的出风方向的步骤包括：判断空调器室内机10的调温模式是否为制热模式，若是，将空调器室内机10的出风方向调整为朝向空隙送风。该实施例的控制方法尤其适用于目标用户的腿部及以下部位被障碍物遮挡的场景。
由于热空气密度比较小，在制热模式下，若周围环境中发生遮挡事件，使得送风气流朝向障碍物的横向两侧的空隙吹送，可以提高送风气流的制热效果。
现有技术中的部分空调器室内机，在识别障碍物识别技术，检测距离较短，且对于尺寸较小的物体(影响实际送风体验的尺寸)不能准确识别，大尺寸障碍物也有一定的误识别几率，分辨率和准确率都达不到能实现精准调节送风的要求。本实施例的空调器室内机利用激光探测装置对周围环境中的障碍物和目标用户进行分析，并根据分析结果调整出风方向和/或出风速度，可以实现避障精准送风，大幅提高了送风效果。

步骤S404，获取激光探测信号的反射信号。
步骤S406，根据反射信号获取目标用户的身体轮廓信息。身体轮廓信息标示有激光探测信号经目标用户的各个身体部位反射的反射信号的强度。
步骤S408，判断身体轮廓信息所标示的激光探测信号经目标用户的各个身体部位反射后的反射信号的强度是否一致，若是，返回执行步骤S402，若否，执行步骤S410。
步骤S410，确定周围环境中发生遮挡事件。
步骤S412，获取空调器室内机10的运行状态和遮挡事件的属性信息。运行状态包括空调器室内机10的调温模式，属性信息包括目标用户的未被障碍物遮挡的有风感身体部位的位置、无风感身体部位的面积、周围环境中障碍物的横向两侧的空隙的位置等信息。
步骤S414，判断空调器室内机10的调温模式是否为制冷模式，若是，执行步骤S416，若否，执行步骤S422。
步骤S416，在目标用户的有风感身体部位的位置为多个的情况下，比较多个有风感身体部位所在位置的高度，得到最高值。
步骤S418，将空调器室内机10的出风方向调整为朝向与最高值相对应的有风感身体部位送风。
步骤S420，在目标用户的无风感身体部位的面积大于设定面积阈值的情况下，将空调器室内机10的出风速度调整为设定出风速度。

例如，在制冷模式下，当周围环境中发生遮挡事件时，空调器室内机10可以朝向目标用户的有风感身体部位送风，并且送风方向可以朝向有风感身体部位中的位置最高的身体部位。
图6是根据本发明另一个实施例的空调器室内机10的使用场景示意图，图中箭头方向示出空调器室内机10的出风方向。
例如，在制热模式下，当周围环境中发生遮挡事件时，并且障碍物遮挡住目标用户的腿部及以下部位时，空调器室内机10可以朝向障碍物横向两侧的空隙送风。若障碍物的横向两侧均存在空隙，则可以针对激光探测信号的反射信号进行进一步分析，判断出距离目标用户最近的空隙的位置，然后驱动空调器室内机10朝向该距离目标用户最近的空隙的位置送风。在另一些可选的实施例中，若障碍物的横向两侧均存在空隙，则可以针对激光探测信号的反射信号进行进一步分析，比较两个空隙的开口大小，然后驱动空调器室内机10朝向开口较大的空隙的位置送风。
本实施例的空调器室内机10及其控制方法，空调器室内机10能驱动激光探测装置200向周围环境发射激光探测信号，并能对激光探测信号的反射信号进行分析，根据分析结果可以确定周围环境中是否发生遮挡事件，在发生遮挡事件的情况下能根据空调器室内 机10的运行状态和遮挡事件的属性信息调整空调器室内机10的出风方向和/或出风速度，从而可使空调器室内机10的送风气流自动避让障碍物，能减少或避免目标用户的部分身体部位因受障碍物遮挡而导致风感差的问题，从而提高空调器室内机10对室内环境空气的调节效果。
本实施例的空调器室内机10，利用激光探测装置200对障碍物和目标用户识别，并根据识别结果调整空调器室内机10的送风方案，在提高识别精度和识别范围的前提下，能够实现避障精准送风，大幅提高了空调器室内机10的送风效果。
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。
