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)、多个贯流风扇200、多个出风口1000、多个导风装置、环境信息检测装置400以及主控板300。其中，壁挂式空调室内机可通过管路与室外机连接，采用蒸气压缩制冷循环***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。每个贯流风扇200对应一个出风口1000，也就是说每个贯流风扇200向对应的出风口1000送风。每个导风装置分别设置于一个出风口1000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1000处，且绕室内机横向的一条转轴转动，用于调整出风口1000的竖向出风方向；摆叶120横向排列于出风口1000内侧，每片摆叶120可沿室内机横向摆动，以调节出风口1000的横向出风方向。
如图1、2所示，在本实施例中，贯流风扇200的数量为两个，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。左侧的贯流风扇200对应左出风口，右侧的贯流风扇200对应右出风口。
如图3所示，环境信息检测装置400设置于两个出风口1000之间，也就是环境信息检测装置400设置于室内机的正中间，能够360°无死角地检测到室内环境。环境信息检测装置400配置成受控地检测室内环境信息，室内环境信息包括用户的人体表面温度、用户位置信息以及用户与空调室内机的距离。在本实施例中，环境信息检测装置400进一步包括人体温度检测模块410、红外检测传感模块420，如图8所示。红外检测传感模块420能够感测室内的用户人数、能够获取每个人体的位置并能够感测人体与其距离，因环境信息检测装置400位于空调室内机之上，可以将其与人体的距离视为人体与空调室内机的距离。利用红外传感器或其他传感器检测人体的数量、位置等均属于本领域技术人员所悉知的，其具体原理在这里不再详述。人体温度检测模块410能够检测室内用户的人体表面温度。利用红外线辐射感测人体温度也是本领域技术所悉知的，其具体原理在这里不再详述。
主控板300配置成在接收到前述的室内环境信息后，控制贯流风扇200的开启数量、贯流风扇200的转速以及送风方向，使得送风方式更加适合当前的室内环境、同时使得空调室内机更加节能。
在本实施例中，空调室内机所在的室内空间可以被划分为两个区域，即第一区域和第二区域。左侧和右侧的贯流风扇200分别向室内的第一区域和第二区域送风。主控板还配置成：在用户集中于室内的第一区域的情况下，单独开启左侧的贯流风扇200，如图6所示；或在用户集中于室内的第二区域的情况下，单独开启右侧的贯流风扇200，若图7所示。根据前文描述，红外检测传感模块420能够感测室内的用户人数、能够获取每个人体的位置，因此，红外检测传感模块420能够获取到位于第一区域和第二区域的人数。主控板300获得上述人数数据之后，计算得到第一区域和第二区域的人数的比例。当上述比例大于预设数值时，则认为用户主要集中于第一区域。同样的，主控板300可以计算第二区域和第一区域人数的比例，当上述比例大于预设数值时，则认为用户主要集中于第二区域。特别地，当某一区域的人数为0时，则在计算比例时，可以默认该区域人数为1，以避免出现计算错误。例如，上述预设数值可以设定为2，若第一区域的人数为3人，第二区域为1人，即第一区域和第二区域的人数比为3，则可以确定用户主要集中于第一区域。此时可以仅开启左侧的贯流风扇200，关闭右侧的贯流风扇200，同时右侧的导风板110封闭出风口1000。
在一些实施例中，主控板300还配置成：判断距空调室内机最近的人体与空调室内机的距离是否小于预设距离；若是，控制贯流风扇200的转速低于第一预设转速；若否，控制贯流风扇200的转速高于第一预设转速。换言之，在人体与空调室内机的距离大于预设距离(如2.5m)后，增加贯流风扇200的转速。例如，贯流风扇200为变频贯流风扇200，可设定第一预设转速为1000rpm。对于具有高速档和低速档两种转速的贯流风扇200而言，当人体与空调室内机的距离大于预设距离，可使其以高速档(即大于第一预设转速)送风。当距离小于预设距离时，使其以低速档(即小于第一预设转速)送风。
在一些实施例中，如图3所示。主控板300还配置成：在制冷模式下，人体温度检测模块410检测到用户的人体表面温度高于第一预设温度的情况下，控制贯流风扇200的转速高于第二预设转速，控制贯流风扇200的出风方向朝向用户，以尽快降低用户体温。在用户的人体表面温度低于第一预设温度的情况下，控制贯流风扇200的转速低于第二预设转速，控制贯流风扇200的出风方向避开用户，以防止用户感觉太冷。在制热模式下，体温度检测模块410检测到用户的人体表面温度高于第二预设温度的情况下，控制贯流风扇200的转速低于第二预设转速，控制贯流风扇200的出风方向避开用户，防止用户感觉太热。在用户的人体表面温度低于第二预设温度的情况下，控制贯流风扇200的转速高于第二预设转速，控制贯流风扇200的出风方向朝向用户，以尽快提高用户体温。上述第一预设温度可以为28℃，第二预设温度可以为20℃。
在一些实施例中，主控板还配置成：根据用户位于室内的具***置，调节导风装置使得贯流风扇200的送风方向朝向用户。红外检测传感模块420能够获取每个用户的具***置，主控板根据用户位置，控制导风板110和/或摆叶120，以调节出风口1000的出风方向，使得出风口1000朝向用户出风。
本发明还提供了一种空调室内机的控制方法，该方法可由上任一实施例的空调室内机执行，以实现智能送风，使贯流风扇200的出风区域、转速以及风向的调节更加精确，不仅提升了用户体验，也能达到节能的目的。
图9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。本实施例的控制方法一般性地可以包括以下步骤：
步骤S902，获取室内环境信息，室内环境包括室内环境温度、用户位置信息以及用户与空调室内机的距离。上述室内环境信息可由环境信息检测装置400的红外检测传感模块420和人体温度检测模块410检测得到，并传输至主控板300。
步骤S904，根据室内环境信息，控制每个贯流风扇200开闭，控制每个贯流风扇200的转速以及送风方向。也就是说，根据人体的聚集区域决定每个贯流风扇200是否开启，根据人体与空调室内机的距离确定转速，根据用户位置确定风向。
图10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，该实施例中，贯流风扇200的数量为两个。该控制方法依次执行以下步骤：
步骤S1002，预先将室内划分第一区域和第二区域，左侧和右侧的贯流风扇200分别向第一区域和第二区域送风。在本实施例中，红外检测模块可以包含两个红外传感器。两个红外传感器分别用于检测第一区域的用户人数及位置信息和第二区域的用户人数及位置信息。
步骤S1004，判断用户是否集中于第一区域。主控板获得上述两个区域的人数数据之后，计算得到第一区域和第二区域的人数的比例。当上述比例大于预设数值时，则确定用户主要集中于第一区域。在本发明的另外一些实施例中，还可以通过绘制室内红外图像，计算热辐射区域的面积来确定用户的集中区域。
步骤S1006，若步骤S1004的判断结果为是，则单独开启左侧的贯流风扇200。也就是，若用户主要集中于室内左侧的第一区域，那么相应的左出风口开启贯流风扇200送 风。而右侧的贯流风扇200关闭，以节省能源。同时，右侧的导风板110可以封闭右侧的出风口。
步骤S1008，若步骤S1004的判断结果为否，则继续判断用户是否集中于第二区域。主控板计算得到第二区域和第一区域的人数的比例。当上述比例大于预设数值时，则认为用户主要集中于第二区域。
步骤S1010，若步骤S1008的判断结果为是，则单独开启右侧的贯流风扇200。也就是，若用户主要集中于室内右侧，那么相应的右出风口开启送风。而左侧的贯流风扇200关闭，以节省能源。同时，左侧的导风板110可以封闭左侧的出风口。
步骤S1012，若步骤S1008的判断结果为否，即用户在两个区域内的人数比较平均，则同时开启两侧的贯流风扇200。
采用本实施例的控制方法首先判断用户的集中区域，并根据用户的集中区域来控制每个贯流风扇200的开闭，而并非持续同时开启两个贯流风扇200。当某一区域用户人数集中，则开启对应的贯流风扇200，同时关闭人数较少区域所对应的贯流风扇200。本实施例的控制方法使得室内机的送风更加智能，同时还能节省能源。
图11是根据本发明另一实施例的壁挂式空调室内机的控制方法的流程图，该实施例的控制方法依次执行以下步骤：
步骤S1102，检测用户与壁挂式空调室内机的距离。使用红外检测传感模块420检测用户人体与室内机的距离，利用红外感测技术测量距离是本领域技术人员均知晓的，此处不再详述。
步骤S1104，判断用户与壁挂式空调室内机的距离是否小于预设距离；
步骤S1106，若步骤S1104的判断结果为是，控制贯流风扇200的转速低于第一预设转速；
步骤S1108，若步骤S1104的判断结果为是，控制贯流风扇200的转速高于第一预设转速。在人体与空调室内机的距离大于预设距离(如2.5m)后，增加贯流风扇200的转速(若同时存在多个用户，则以最靠近室内机的人体为测量标准)。例如，贯流风扇200为变频贯流风扇200，可设定该第一预设转速为1000rpm。对于具有高速档和低速档两种转速的贯流风扇200而言，当人体与空调室内机的距离大于预设距离，可使其以高速档送风。当距离小于预设距离时，使其以低速档送风。
在本实施例中，室内机可以根据用户距离室内机的远近程度，适当调整风速。用户无论处于室内哪个位置，都能够感受到适宜的风速，提高了用户体验。
图12是根据本发明又一实施例的空调室内机的控制方法的流程图，该控制方法适用于空调处于制冷模式，该实施例的控制方法依次执行以下步骤：
步骤S1202，检测用户的人体表面温度。
步骤S1204，判断人体表面温度是否高于第一预设温度。在本实施例中，可通过温度传感器检测人体表面温度，同时主控板可以获取第一预设温度值。在本实施例中，上述第一预设温度值可以设定为28℃。
步骤S1206，若步骤S1204的判断结果为是，控制贯流风扇的转速高于第二预设转 速，控制贯流风扇的出风方向朝向用户。当检测到人体表面温度过高时(高于第一预设温度)，控制贯流风扇200以高转速运行(即大于第二预设转速)，提高室内机出风风速，同时控制导风装置使得出风方向朝向用户，以尽快降低用户体温，令用户感到更加凉爽。在调节出风方向时，可以通过控制导风板110调节出风口1000的竖向出风方向，控制多个摆叶120调节出风口1000的横向出风方向，以实现出风精确吹向用户。
步骤S1208，若步骤S1204的判断结果为否，控制贯流风扇200的转速低于第二预设转速，控制贯流风扇的出风方向避开用户。当检测到人体表面温度过低时(低于第一预设温度)，此时不再需要快速降温。控制贯流风扇200以低转速运行(即小于第二预设转速)，同时控制导风装置避开用户出风，防止用户感到温度过低，影响用户舒适度。
特别地，如果室内存在多位用户，则可以选择最靠近室内机的用户作为检测目标。
图13是根据本发明又一实施例的空调室内机的控制方法的流程图，该控制方法适用于空调处于制热模式，该实施例的控制方法依次执行以下步骤：
步骤S1302，检测用户的人体表面温度。
步骤S1304，判断人体表面温度是否高于第二预设温度。在本实施例中，可通过温度传感器检测人体表面温度，同时主控板可以获取第二预设温度值。上述第二预设温度值可以设置为20℃。
步骤S1306，若步骤S1304的判断结果为是，控制贯流风扇的转速低于第二预设转速，控制贯流风扇的出风方向避开用户。当检测到人体表面温度过高时(高于第二预设温度)，控制贯流风扇200以低转速运行(即小于第二预设转速)，降低室内机出风风速，同时控制导风装置使得出风方向避开用户，以尽快降低用户体温，从而不会令用户感到过热。在调节出风方向时，可以通过控制导风板110调节出风口1000的竖向出风方向，控制多个摆叶130调节出风口1000的横向出风方向，以实现出风精确吹向用户。
步骤S1308，若步骤S1304的判断结果为否，控制贯流风扇200的转速高于第二预设转速，控制贯流风扇的出风方向朝向用户。当检测到人体表面温度过低时(低于第二预设温度)，控制贯流风扇200以高转速运行(即高于第二预设转速)，同时控制导风装置朝向用户出风，防止用户感到温度过低，影响用户舒适度。
采用本实施例的控制方法首先检测当前人体表面温度，能够根据用户的实际情况，调整出风模式，以避免出现让用户感觉到过冷或过热的情况。本实施例的控制方法使得室内机送风更加智能，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。
