具体实施方式
本实施例首先提供了一种具有空气净化功能的空调器室内机，该空调器的净化功能可以根据需要进行开启和关闭。空调器的室内机内设置有驱动装置以及净化组件，其中净化组件为柔性材料制成，其具有固定设置于室内机进风口的一侧的固定端和在驱动装置的带动下伸缩的活动端，净化组件通过活动端的伸缩改变覆盖室内机进风口的面积，从而可以改变进入室内机的空气被过滤的程度。在空气质量较差的情况下，使得净化组件尽量完全覆盖进风口，从而使得空气进行全面过滤；在空气污染程度一般的情况下，可以使净化组件覆盖进风口的一部分，使得部分空气经过过滤。本实施例的具有空气净化功能的空调器室内机一方面满足了空气净化的要求，另一方面也尽量减少净化组件产生的风阻，减小了对空调正常调温功能产生影响。
该具有空气净化功能的空调器室内机可以优选为壁挂式室内机，由于壁挂式室内机结构更加紧凑，因此布置净化组件的空间更加狭小，本实施例通过优化壁挂式室内机的结构，利用更加紧凑的结构实现了在实现上述净化功能。图1是根据本发明一个实施例的具有空气净化功能的空调器室内机100的示意性结构图。图2是图1所示的空调器室内机100中净化组件150在部分拉伸状态下的示意性结构图。图3是1所示的空调器室内机100中净化组件150在部分收缩状态下的示意性结构图。图4是图1所示的空调器室内机100中净化组件150在完全拉伸状态下的示意性剖视图；图5是图1所示的空调器室内机100中净化组件150在完全收缩状态下的示意性剖视图。
该壁挂式空调室内机100一般性地可以包括机体骨架110、罩壳120、前面板130、驱动装置140和净化组件150等。机体骨架110构成换热器160和风机170的容纳空间，罩壳120罩在机体骨架110的前部，以封闭换热器160和风机170，罩壳120的顶部形成有进风口121，罩壳120固定在机体骨架110上，罩壳120的前部设置有前面板130，前面板130可拆卸地安装在罩壳120上。
净化组件150具有相对设置的固定端150-1和活动端150-2。固定端150-1可直接连接或通过其他连接结构设置于罩壳120上，以和空调室内机100的机身固定。活动端150-2连接于驱动装置140，以使活动端150-2在驱动装置140的驱动下相对于固定端150-1移 动。固定端150-1可连接在罩壳120的内侧后部或内部上表面上。也即是，位于进风口121后侧或进风口121后侧的下方。活动端150-2及驱动装置140可移动地设置在罩壳120上，且活动端150-2及驱动装置140可在进风口121内侧前后移动。
驱动装置140设置在罩壳120上，净化组件150的活动端150-2与驱动装置140连接，净化组件150的活动端150-2由驱动装置140的驱动可以朝向或背离固定端150-1移动，以压缩或拉伸净化组件150，使净化组件150在净化模式与非净化模式之间转换。
净化组件150的活动端150-2在净化模式下可以由驱动装置140驱动背离固定端150-1移动，以使净化组件150拉伸，逐渐遮蔽进风口121，调整遮蔽进风口121的面积，从而可对进入室内机100的气流进行净化。净化组件150的活动端150-2在退出净化模式时可以由驱动装置140驱动朝向固定端150-1移动，以使净化组件150压缩，从而将进风口121显露，气流不经过净化组件150直接进入室内机100中。
本实施例的具有空气净化功能的空调器室内机100为不同的净化要求设置了不同的活动端位置，对应改变净化组件120覆盖进风口121的面积。例如当空气质量极差时，净化组件150的活动端150-2可以被驱动装置140带动至使净化组件150完全遮蔽进风口121的位置。在空气质量为一般污染时，可以使净化组件150遮蔽进风口121的一半面积。在空气质量较优时，可以使净化组件150完全显露出进风口121，使空气不经过净化直接进入室内机100内部。
上述驱动装置140可以通过齿轮齿条传动组件实现，例如驱动装置140可以包括导轨组件、电机、齿轮和弧形齿条。导轨组件可以设置在罩壳的横向侧端的边框处。电机可以设置在导轨组件上，齿轮与电机的输出轴连接，弧形齿条与齿轮啮合，净化组件150的活动端150-2直接或间接连接在弧形齿条上，电机141通过齿轮和弧形齿条驱动净化组件150的活动端150-2沿导轨组件滑动。
图6是根据本发明一个实施例的具有空气净化功能的空调器室内机100中驱动装置140和净化组件150的示意性分解图。图7是图6所示的具有空气净化功能的空调器室内机100中驱动装置140的示意性分解图，图8是根据本发明一个实施例的具有空气净化功能的空调器室内机100中净化组件150活动端的移动轨迹示意图。
驱动装置140可以包括导轨组件、电机141、齿轮142、弧形齿条143和连杆146。导轨组件可以设置在罩壳120的横向侧端的边框处。
净化组件150的活动端150-2通过连杆146与弧形齿条143连接。具体地，连杆146的第一端与弧形齿条143转动连接，电机141驱动齿轮142转动，齿轮142带动弧形齿条143滑动，弧形齿条143带动与其转动连接的连杆146转动并滑动。并且，连杆146的第二端与净化组件150的活动端150-2转动连接，净化组件150的活动端150-2由连杆146带动可转动且可滑动地与导轨组件配合。由此使得净化组件150的活动端150-2朝向或背离固定端150-1移动，以收缩或拉伸净化组件150。
导轨组件可以包括基座144和侧盖145，基座144设置在罩壳120的横向侧端的边框处，例如基座144可通过螺钉固定在罩壳120的横向侧端的边框处，侧盖145扣合在基座144远离横向侧端的一面，侧盖145与基座144构成容纳齿轮142和弧形齿条143的空间，电机141的输出轴穿过基座144与齿轮142连接，电机141通过齿轮142驱动弧形齿条143滑动。
连杆146布置在基座144和侧盖145构成的容纳空间中，连杆146的第一端与弧形齿条143转动连接，连杆146的第二端与净化组件的活动端150-2转动连接，连杆146带动净化组件150的活动端150-2可转动并可滑动地与导轨组件配合，由此使得净化组件150的活动端150-2朝向或背离固定端150-1移动，以收缩或拉伸净化组件150，使净化组件150在净化模式与非净化模式之间转换。
连杆146的第二端可设置有定位滑柱146-1，定位滑柱146-1穿过侧盖145与净化组件150的活动端150-2转动连接，第二导轨145-7在其延伸方向上形成有镂空区，定位滑柱146-1穿过镂空区与净化组件150的活动端150-2转动连接，连杆146随弧形齿条143运动的过程中，定位滑柱146-1在镂空区中滑动，同时带动净化组件150的活动端150-2沿第二导轨145-7运动。
净化组件150的活动端150-2由连杆146的驱动由前面板内侧的位置运动至进风口121后侧的位置，以收缩净化组件150，并显露出进风口121，使得气流不经过净化组件150的净化直接进入室内机100。
净化组件150的活动端150-2由连杆146的驱动由进风口121后侧的位置运动至前面板内侧的位置，以拉伸净化组件150，对气流进行过滤净化。
基座144朝向弧形齿条143的一侧还可以形成有弧形槽144-4，弧形齿条143靠近基座144的一侧设置有至少一个第二滚轮143-3，第二滚轮143-3可以容纳在弧形槽144-4中并与弧形槽144-4滑动相接。由此可以使得弧形齿条143沿弧形槽144-4稳定滑动，提高驱动装置140运行的稳定性。
侧盖145远离基座144的一侧可以形成有第二导轨145-7，净化组件150的活动端150-2由连杆146的带动可转动且可滑动地与第二导轨145-7配合，以朝向或背离固定端150-1移动，以收缩或拉伸净化组件150，使净化组件150在净化模式与非净化模式之间转换。
电机141通过齿轮142驱动弧形齿条143沿弧形槽144-4滑动，弧形齿条143在滑动过程中，连杆146随弧形齿条143滑动，并与弧形齿条143之间产生转动的相对运动，净化组件150的活动端150-2由连杆146带动并配合第二导轨145-7的路径沿第二导轨145-7运动，由此改变净化组件150覆盖进风口121的面积。
第二导轨145-7可以包括第一弧形段145-7-1和与第一弧形段145-7-1相接的第二弧形段145-7-2，第一弧形段145-7-1与第二弧形段145-7-2的弧度不同，也即是指第一弧形段145-7-1与第二弧形段145-7-2的弯曲程度不同，由此形成了与净化组件150的活动端150-2运动路径一致的不规则形状的第二导轨145-7，第一弧形段145-7-1可位于罩壳120横向侧端的边框与进风口121对应的位置，第二弧形段145-7-2向前下方延伸至前面板130的内侧。弧形槽144-4也可延伸至前面板130的内侧，第二弧形段145-7-2可位于弧形槽144-4的外侧，也即是说，与弧形槽144-4所在的位置相比，第二弧形段145-7-2更靠近前面板130。
电机141驱动齿轮142转动，齿轮142驱动弧形齿条143在弧形槽144-4中滑动，弧形齿条143在滑动过程中，连杆146随弧形齿条143滑动，并与弧形齿条143之间产生转动的相对运动，净化组件150的活动端150-2由连杆146带动沿不规则形状的第二导轨145-7可以在前面板130的内侧的位置与进风口121的内侧的位置之间运动，由此 压缩或拉伸净化组件150，实现净化组件150在净化模式与非净化模式之间的转换，并且净化组件150的活动端150-2的运动路径位于弧形槽144-4的外侧。
连杆146带动净化组件150的活动端150-2配合不规则形状的第二导轨145-7的运动所占的空间更小，可以节省空调器室内机100的内部空间。在图8中A为由第一弧形段145-7-1和与第一弧形段145-7-1弧度不同的第二弧形段145-7-2相接而成的不规则形状的第二导轨145-7的路径，B为呈弧形的第一导轨145-3的路径，不规则形状的第二导轨145-7位于呈弧形的第一导轨145-3的外侧。净化组件150的活动端150-2由连杆146带动沿不规则形状的第二导轨145-7的运动所需空间更小，可以让出室内机100的更多内部空间，无需增大室内机100的体积，在布置驱动装置140和净化组件150的同时，也可为换热器160、风机170及其他部件的布置提供足够的空间。
净化组件150的活动端150-2可以与驱动装置140可拆卸连接，方便净化组件150的清洗和更换。净化组件150可以包括托架和置于托架上的净化模块151。净化模块151的形状和大下可以根据室内机100的内部空间和进风口121的大小进行确定，净化模块151可以由多层柔性过滤网叠加形成，例如可以高效过滤空气中的微颗粒物。
托架可以包括两个相对设置的连接部152，连接部152之间可以设置一横杆153，横杆153的两端分别与两个连接部152连接，净化模块151的前端抵靠在横杆153上。在弧形齿条143直接带动净化组件150沿呈弧形导轨滑动的方案中，两个连接部152直接与对应的弧形齿条143连接；在弧形齿条143通过连杆146带动净化组件150的活动端150-2沿不规则形状的第二导轨145-7运动的方案中，两个连接部152与对应的连杆146转动连接。净化模块151的前端设置在连接部152上并位于两个连接部152之间。净化模块151的后端可直接固定在前面板内侧，以构成净化组件150的固定端150-1。净化模块151的前端和托架共同构成净化组件150的活动端150-2。
本实施例具有空气净化功能的空调器室内机100通过对驱动装置140控制方式的优化，设置多个净化等级，适应于不同的工作环境。图9是根据本发明一个实施例的具有空气净化功能的空调器室内机100的功能框图，净化组件140通过活动端150-2的伸缩改变覆盖室内机进风口121的面积，驱动装置140的工作过程包括：在获取空调器进入净化模式的触发信号后，根据空调器室内机100工作环境的空气污染参数确定对应的净化等级，将活动端150-2带动至对应的净化等级的规定的位置，以对进入室内机100的气流进行净化，其中每个净化等级预先规定有净化组件150需覆盖进风口121的面积。上述净化等级可以设置为三档或者更多，例如在无需净化时，净化组件140可以完全显露出进风口121，使全部空气不经过净化；在需要完全净化时净化组件140可以完全遮蔽进风口121，使全部空气经过净化。在完全显露出进风口121至完全遮蔽进风口121之间，可以为设置一个多个中间位置，例如分别在遮蔽进风口121的面积三分之一、三分之二的位置设置活动端的净化位置。
本实施例具有空气净化功能的空调器室内机100中设置有空气质量检测装置180。该空气质量检测装置180配置成检测空调器室内机100工作环境的空气污染参数。进入净化模式的触发信号可以包括：空气质量检测装置180上报的空气污染超限信号、来自于用户的启动操作信号、定时启动信号。在本实施例中，空气质量检测装置180可以在空气污染参数超过预设净化启动阈值时，自动输出触发信号，启动净化。净化启动阈值可 以根据空气质量进行配置。
在启动净化后，驱动装置140还可以根据空气污染参数的变化并相应调整净化等级，直至满足退出净化的触发条件。退出净化的触发条件包括以下任意一项或多项：空气污染参数降低至预设的净化关闭阈值的信号；净化时间超时的信号；空气污染参数持续无改善的信号。例如经过净化，空调器室内机100工作环境已经得到改善，那么可以退出净化。另外如果持续净化时间超过一定的时间，也可以退出净化。在净化过程中，如果空气污染参数持续无改善或者出现恶化的情况，说明净化组件150没有起到作用，此时也可以退出净化。
室内机风机170可以根据净化等级确定对应的转速调整方案；并按照室内机风机170转速调整方案对转速进行调整。一种具体的转速调整方案为：
在净化组件150需覆盖进风口的面积小于设定的第一遮蔽面积阈值时，维持室内机的风机170转速不变，该第一遮蔽面积阈值可以设置较小，例如覆盖的面积不超过进风口121的三分之一的情况下，认为净化组件150造成的风阻较小，可以维持室内机风机170转速不变。
在净化组件需覆盖述进风口的面积大于第一遮蔽面积阈值并且小于设定的第二遮蔽面积阈值时(例如覆盖的面积大于进风口121的三分之一但小于进风口的三分之二时)，将室内机的风机170转速提高一个风速等级，例如将低风运行的室内机的风机170调整为中风运行，将中风运行的室内机风机170调整为高风运行，将高风运行的室内机风机170调整为强力运行。
在净化组件150需覆盖进风口121的面积大于第二遮蔽面积阈值(例如覆盖的面积大于进风口121的三分之二时)，按照室内机的换热器160的管温对室内机的风机170转速进行反馈控制。
由于净化过程中，室内机风机170产生气流的风阻明显不同，在开启净化功能后，气流经过过滤，必然导致经过换热器160的换热效果衰减，容易出现高负荷问题，本实施例的室内机100在净化组件150需覆盖进风口121的面积大于第二遮蔽面积阈值时，可以设定室内机100的换热器160管温的目标管温，并实时检测室内机100的换热器管温，根据检测管温与目标管温的温差对室内机风机170进行反馈控制，从而稳定换热器160管温，防止换热器160过热或者过冷，出现高负荷问题。
如果通过调节室内机风机170不能保证换热器160温度稳定，还可以进一步调整压缩制冷循环的节流装置以及压缩机的工作状态。压缩制冷循环利用制冷剂在压缩机、冷凝器、蒸发器、节流装置的压缩相变循环实现热量的传递。在空调器中，制冷系统还可以设置换向阀，改变制冷剂的流向，使室内机换热器160交替作为蒸发器或冷凝器，实现制冷或者制热功能。由于空调器中压缩制冷循环是本领域技术人员所习知，其工作原理和构造再次不做赘述。在本实施例中，压缩机使用变频压缩机，节流装置使用开度可调的电子膨胀阀。具体的控制方案可以为：
在空调器制冷运行时，如果在净化后换热器160管温低于目标管温不超过第一温差阈值(例如3度)时，可以根据差值对室内机100的风机170进行反馈控制，换热器160管温温度越低，室内机100的风机170转速越快。如果室内机100风机170转速的提升不能保证换热器160管温维持在与目标管温温差在第一温差阈值以内时，则增加压缩制 冷循环的节流装置的开度，如果仍不能保证换热器160管温维持在与目标管温温差在第二温差阈值以内时，则对压缩机进行降频，从而防止室内机换热器160温度过低而出现高负荷。
在空调器进行制热运行时，如果在净化后换热器160管温高于目标管温不超过第一温差阈值(例如3度)时，可以根据差值对室内机100的风机进行反馈控制，换热器160管温温度越高，室内机100的风机转速越快。如果室内机100风机转速的提升不能保证换热器160管温维持在与目标管温温差在第一温差阈值以内时，则增加压缩制冷循环的节流装置的开度，如果仍不能保证换热器160管温维持在与目标管温温差在第二温差阈值以内时，则对压缩机进进行降频，从而防止室内机100换热器温度过高而出现高负荷。
上述第一温差阈值和第二温差阈值可以根据室内机换热器160的规格和使用要求进行配置，例如将第一温差阈值设置正负3摄氏度，将第二温差阈值设置为正负5摄氏度。
以下结合本实施例的具有空气净化功能的空调器室内机100的控制方法，对上述实施例的空调器室内机100的控制过程进行进一步说明，本实施例的带有具有空气净化功能的空调器室内机100的控制方法可以由上述介绍的具有空气净化功能的空调器室内机100执行，通过对驱动装置140、室内机风机170、空气质量检测装置180的控制，满足净化要求。图10是根据本发明一个实施例的具有空气净化功能的空调器室内机100的控制方法的示意图。该控制方法一般性地可以包括：
步骤S1002，获取空调器进入净化模式的触发信号；这些触发信号可以包括但不限于：空气质量检测装置180上报的空气污染超限信号、来自于用户的启动操作信号、定时启动信号。
对于空气污染超限信号，空气质量检测装置180检测到空调器的工作环境的空气污染到达设定超限阈值(例如各项参数超限或者污染等级超限等)后，可以触发空调器进入净化模式。
对于启动操作信号，用户可以通过遥控器或者其他空调器人机交互接口，手动触发空调器进入净化模式。
对于定时启动信号，空调器可以根据运行时间，定期进行净化，例如累计工作8小时，开始净化1小时。
空调器进入净化模式的触发信号可以根据用户对空气净化的要求进行设置。在本实施例中，空气质量检测装置180可以在空气污染参数超过预设净化启动阈值时，自动输出触发信号，启动净化。
步骤S1004，检测空调器室内机100工作环境的空气污染参数，并确定空气污染参数对应的净化等级；空气质量检测装置180可以检测工作环境中微颗粒物指数等参数，从而相应确定空气污染参数对应的净化等级。每个净化等级规定有净化组件需覆盖进风口121的面积。
步骤S1006，控制驱动装置140将活动端150-2带动至确定出的净化等级的规定的位置，以对进入室内机100的气流进行净化。
在启动净化后，也即将活动端带动至净化等级的规定的位置之后还可以持续检测空气污染参数，根据空气污染参数的变化并相应调整净化等级，直至满足退出净化的触发条件。退出净化的触发条件包括以下任意一项或多项：空气污染参数降低至预设的净化 关闭阈值的信号；净化时间超时的信号；空气污染参数持续无改善的信号。例如经过净化，空调器室内机100工作环境已经得到改善，那么可以退出净化。另外如果持续净化时间超过一定的时间，也可以退出净化。在净化过程中，如果空气污染参数持续无改善或者出现恶化的情况，说明净化组件150没有起到作用，此时也可以退出净化。
为了减小净化组件150造成的风阻增大，在步骤S1006之后还可以根据净化等级确定对应的室内机风机170转速调整方案；按照室内机风机转速调整方案对室内机的风机170转速进行调整。
例如覆盖的面积不超过进风口121的三分之一的情况下，认为净化组件150造成的风阻较小，可以维持室内机风机170转速不变。
在净化组件需覆盖述进风口的面积大于第一遮蔽面积阈值并且小于设定的第二遮蔽面积阈值时(例如覆盖的面积大于进风口121的三分之一但小于进风口的三分之二时)，将室内机的风机170转速提高一个风速等级，例如将低风运行的室内机的风机170调整为中风运行，将中风运行的室内机风机170调整为高风运行，将高风运行的室内机风机170调整为强力运行。
在净化组件150需覆盖进风口121的面积大于第二遮蔽面积阈值(例如覆盖的面积大于进风口121的三分之二时)，按照室内机的换热器160的管温对室内机的风机170转速进行反馈控制。
由于净化过程中，室内机风机170产生气流的风阻明显不同，在开启净化功能后，气流经过过滤，必然导致经过换热器160的换热效果衰减，容易出现高负荷问题，本实施例的室内机在在净化组件150需覆盖进风口121的面积大于第二遮蔽面积阈值时，可以设定室内机100的换热器160管温的目标管温，并实时检测室内机100的换热器管温，根据检测管温与目标管温的温差对室内机风机170进行反馈控制，从而稳定换热器160管温，防止换热器160过热或者过冷，出现高负荷问题。
如果通过调节室内机风机170不能保证换热器160温度稳定，还可以进一步调整压缩制冷循环的节流装置以及压缩机的工作状态。具体的控制方案可以为：
在空调器制冷运行时，如果在净化后换热器160管温低于目标管温不超过第一温差阈值(例如3度)时，可以根据差值对室内机100的风机170进行反馈控制，换热器160管温温度越低，室内机100的风机170转速越快。如果室内机100风机170转速的提升不能保证换热器160管温维持在与目标管温温差在第一温差阈值以内时，则增加压缩制冷循环的节流装置的开度，如果仍不能保证换热器160管温维持在与目标管温温差在第二温差阈值以内时，则对压缩机进行降频，从而防止室内机换热器160温度过低而出现高负荷。
在空调器进行制热运行时，如果在净化后换热器160管温高于目标管温不超过第一温差阈值(例如3度)时，可以根据差值对室内机100的风机进行反馈控制，换热器管温温度越高，室内机100的风机转速越快。如果室内机100风机转速的提升不能保证换热器160管温维持在与目标管温温差在第一温差阈值以内时，则增加压缩制冷循环的节流装置的开度，如果仍不能保证换热器管温维持在与目标管温温差在第二温差阈值以内时，则对压缩机进进行降频，从而防止室内机100换热器温度过高而出现高负荷。
上述第一温差阈值和第二温差阈值可以根据室内机换热器160的规格和使用要求进 行配置，例如将第一温差阈值设置正负3摄氏度，将第二温差阈值设置为正负5摄氏度。
利用上述控制方法设置多个净化等级，相应调整过滤面积，满足了净化要求，提高了用户的使用体验。
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。
