本发明的进一步的目的是要使得空调器的功能可以按需要启停，避免净化功能始终工作。
本发明的另一个进一步的目的是便于用户更换和清洁净化组件，防止二次污染。
特别地，本发明提供了一种带有净化功能的空调器室内机的控制方法，其中空调器室内机设置有驱动装置以及净化组件，净化组件由驱动装置带动移入或移出遮蔽室内机的出风口的净化位置，并且上述控制方法包括：检测空调器室内机工作环境的空气污染参数；在空气污染参数超过预设净化启动阈值的情况下，控制驱动装置将净化组件移动至净化位置，以利用净化组件对室内机的出风进行净化；持续检测空气污染参数，在出现净化组件进行净化的持续时间超过设定时间且空气污染参数无改善的情况下，控制驱动装置带动净化组件移出净化位置到达位于空调器室内机外部的更换位置，以供用户对净化组件进行维护。

可选地，输出提示更换或清理净化组件的提示信息包括：利用室内机内设置的提示灯输出对应的提示信号；或者向空调器的遥控装置反馈提示信息，以使遥控装置的屏幕显示对应于提示信息的图标。
根据本发明的另一个方面，还提供了一种带有净化功能的空调器室内机，其包括：机壳，其上开设有用于向周围环境送风的出风口；空气质量检测装置，配置成检测空调器室内机工作环境的空气污染参数；净化组件，其配置成由驱动装置带动移入或移出遮蔽出风口的净化位置，驱动装置，配置成在空气污染参数超过预设净化启动阈值的情况下，受控地将净化组件移动至净化位置，以利用净化组件对室内机的出风进行净化，并且在出现净化组件进行净化的持续时间超过设定时间且空气污染参数无改善的情况下，受控地将净化组件移出净化位置到达位于空调器室内机外部的更换位置，以供用户对净化组件进行维护。

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7是根据本发明一个实施例的带有净化功能的空调器室内机的控制方法的示意图。
具体实施方式
本实施例提供了一种带有净化功能的空调器室内机，该空调器室内机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，其中净化组件由驱动装置带动在室内机的出风口处的净化位置与移出进风口的位置之间移动，在不开启净化功能时，净化组件移出出风口，在开启净化功能后，净化组件由驱动装置带动，移动至室内机的出风口处的净化位置，对室内机送出气流进行净化。
由于净化组件在净化过程中，自身的净化功能会逐渐下降，因此需要进行更换或进行清洁维护，一种可选的提醒维护方案为，定期更换，然而定期更换没有考虑到净化组件的实际使用时间。在本实施例的空调器室内机中，净化功能可以根据需要进行开关，因此净化组件实际处于净化位置的时间并不确定，因此定期更换的方案并不适用本实施例的带有净化功能的空调器室内机。而且由于净化组件可移动设置，给更换拆卸也带来了不便。
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所示的具有空气净化功能的空调器室内机100的另一角度的示意图。该实施例的带有净化功能的空调器室内机100一般性地可包括用于支撑风机180和换热器160的骨架110、罩设在骨架110上的罩壳120和设置在罩壳120前部以形成空调器室内机100前表面的前面板130。具体地，罩壳120的顶部设置有进风格栅，进风格栅上形成有进风口101以允许环境空气进入空调器室内机100。骨架110、罩壳120和前面板130可共同构成空调器室内机100的机壳。机壳下部开设有出风口102，以用于向室内送风。
空调器室内机100还包括净化组件150和至少一个驱动装置140。驱动装置140可设置在机壳内，净化组件150连接于驱动装置140，并配置成受 驱动装置140的驱动移入或移出遮蔽室内机的出风口102的净化位置。
净化组件150在净化模式下配置成由驱动装置140带动移入出风口102的净化位置(例如可以完全遮蔽出风口102)，以对室内机排出的气流进行净化。净化组件150在非净化时，可以由驱动装置驱动移出出风口102至备用位置，以显露出风口102，从而使得气流不经过净化组件150直接流出机壳。进一步地，通过延长驱动装置140的行程，净化组件150还可以从备用位置进一步移出室内机100外部，到达更换位置，便于用户进行更换和清洁净化组件150。
本实施例的空调器室内机100由于设置了可移动的净化组件150，因此可以在空气质量需要改善的时候，使净化组件150移动至出风口102的内侧以遮蔽出风口102，从而对将要流出空调器室内机100的气流进行净化，提升室内环境的空气质量，净化组件150在对空气进行净化时位于出风口102处，也即风机180的出风路径上，从而能够将其风阻对空调器室内机100的出风量及出风风速的影响降到最低，进而能够在保证空调器室内机100的制冷及制热效率的同时，使室内空气得到净化。
在本发明的一些实施例中，驱动装置140可配置成可受控沿机壳的前表面内侧上下移动。净化组件150可连接于驱动装置140，并配置成由驱动装置140的带动在机壳内上下移动。特别地，净化组件150可受控上移至出风口102的内侧，并完全遮蔽出风口102，以对机壳内的流向出风口102的气流进行净化。
在无需净化时，净化组件150由驱动装置的驱动下移至备用位置(例如机壳的位于出风口102下方的外侧或内侧)。
图3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在净化状态下的示意性侧向剖视图。图4是图3所示的具有空气净化功能的空调器室内机100在备用状态下的侧向剖视图。在需要净化时，空调器室内机100的净化组件150可受驱动装置140的带动移动至正对出风口102的位置，并在机壳内侧将出风口102完全覆盖。由此，可以使得由出风口102送出的气流得到净化，也即是使将要自出风口102流出机壳的全部空气均需先流经净化组件150进行净化，从而使得室内环境空气的质量能够逐渐优化直至满足用户需求。
当无需净化时，净化组件150可在驱动装置140的驱动下由出风口102内侧下移至备用位置(例如机壳的位于出风口102下方的外侧或内侧)。也即净化组件150可移动至机壳的下方，从而将出风口102显露，由此可以降 低出风口102处风阻，使得空调器更加节能环保。
当需要更换和清洁净化组件150时，净化组件150可在驱动装置140的驱动下进一步从备用位置继续向下方后方移动至室内机100外部，便于用户进行操作。
空调器室内机100还具有设置在进风口处的滤尘网，气流进入机壳时，先经过滤尘网过滤其中的灰尘、颗粒等杂质，可以避免气流中的灰尘、颗粒等杂质流经净化组件150而影响净化组的使用，同时，也避免了净化组件150在长时间使用后堆积灰尘而需要频繁清洗或更换。
图5是根据本发明一个实施例的壁挂式空调器室内机中净化组件150和驱动装置的示意性结构图。参见图5，在本发明的一些实施例中，驱动装置140可包括电机141、齿轮142和弧形齿条143。电机141可固定在罩壳120的横向侧端，并配置成可受控输出两个方向相反的驱动力。齿轮142可配置成与电机141的输出轴同轴连接，以在电机141的驱动下旋转。弧形齿条143可配置成与齿轮142啮合，以在齿轮142的带动下沿其自身延伸方向移动。进一步地，净化组件150可配置与弧形齿条143连接，以随弧形齿条143移动。
在本发明的一些实施例中，驱动装置140可以优选地为两个，两个驱动装置140沿横向相对设置在机壳内部。具体地，可以分别位于形成机壳的左右侧表面的左右端盖的内侧。
进一步地，净化组件150的横向两端可分别与两个驱动装置140的弧形齿条143连接，由此使得净化组件150在出风口102处的移动更加稳定。
在本发明的另一些实施例中，罩壳120可具有多个支撑框架，支撑框架可配置成自进风口101的下方沿一弧形曲线延伸至出风口102处。支撑框架和骨架110共同限定出用于设置风机180和换热器160的内部空间。两个驱动装置140可并分别设置在位于罩壳120左右两侧的两个支撑框架的下部。两个驱动装置140可镜像地对称设置在两个支撑框架上。此时，两个驱动装置140的两个电机141同时输出相反方向的驱动力，从而使得两个驱动装置140的两个弧形齿轮142能够同步地朝向同一方向移动。
在本发明的一些实施例中，每个驱动装置140还可包括限位部(图中未示出)，限位部可设置在齿条的外侧表面上。进一步地，机壳上可设置与限位部相对应的限位槽。例如可以为，在罩壳120的某一个或几个支撑框架的与限位部相对应的位置处设置限位槽，且限位槽配置成具有与限位部随齿条移动所产生的运动路径一致的延伸方向，从而可通过限位部与限位槽的配合 关系约束齿条的移动方向。当然，本领域技术人员也可选取其他适当的机构对齿条的自由度进行约束，这里不再赘述。
在本发明的一些实施例中，弧形齿条143的齿位于其凹侧。弧形齿条143具有自其背离齿轮142的凸侧表面向外延伸出的多个其上开设有通孔的连接件，以用于与净化组件150连接。进一步地，多个连接件配置成间隔地位于弧形齿条143的上部。
也即是，弧形齿条143的凹侧与齿轮142啮合并围绕其转动/移动。弧形齿条143可配置成具有较平缓的、与空调器室内机前面板130的弯曲度相类似的弧度。相应地，弧形齿条143可配置成具有与弧形齿条143仿形的弧形形状，由此，当净化组件150随弧形齿条143转动/移动至出风口时可以更加贴合机壳的前表面，从而避免对换热器160或风机180的安装空间产生干扰，且使空调器室内机更加美观。
在本发明的一些实施例中，净化组件150的横向端面上相应开设有多个间隔设置的连接孔，多个连接孔分别与多个连接件的通孔一一对应，并通过多个连接销连接，以使净化组件150连接在弧形齿条143上。
在本发明的另一些实施例中，净化组件150的端面上也可相应向外延伸出多个连接柱，并与多个连接件的通孔一一对应配合。由于净化组件150与弧形齿条143的多个连接点间隔设置，且二者的移动方向均大致为竖直向上及向下。由此，通过简单的横向设置的连接件即可使净化组件150稳固地连接在弧形齿条143上，且其在移动过程中不会出现翻转等问题。
在本发明的一些实施例中，净化组件150配置成，当弧形齿条143移动至使位于其上端的齿与齿轮142啮合的位置时，净化组件150整体移出室内机100外部，其上侧边缘不高于出风口102下沿，以使出风口102完全打开。相应地，当弧形齿条143移动至使位于其下端的齿与齿轮142啮合的位置时，净化组件150的上侧边缘不低于出风口102上沿，其下侧边缘不高于出风口102下沿，以使出风口102被净化组件150完全遮蔽。
具体地，净化组件150的长度大致可以为弧形齿条143的1/3至1/2，且其安装位置设置在弧形齿条143的上半部分上。由此，使得净化组件150和弧形齿条143的上端边缘可位于同一平面内，且当出风口102被完全打开时，出风口102下沿也可落入该平面内。从而将驱动装置所需的移动行程降到最小，也即是能够尽可能地减小弧形齿条143的长度，降低整体的制造成本，节约安装空间。
在正常使用时，净化组件150由驱动装置140带动在完全遮蔽室内机的 出风口的净化位置与离开出风口的备用位置之间移动，在不开启净化功能时，净化组件150位于移出出风口达到备用位置；在开启净化功能后，净化组件150由驱动装置140带动，移动至完全遮蔽室内机的出风口的净化位置，对进入室内机的气流进行净化。
在需要更换和清洁净化组件150时，可以使弧形齿条143的行程达到最大，使净化组件150移出室内机100外部，便于更换。净化组件150的备用位置可以位于出风口102的下方，更换位置位于出风口102的下后方。
在本发明的一些实施例中，还可以设置分别对应于净化位置、备用位置和更换位置的限位开关，以对净化组件150的位置进行指示，提高驱动装置140的运动精度。
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的功能框图，该具有空气净化功能的空调器室内机100具有：净化组件150、驱动装置140、空气质量检测装置170、提示装置190、室内机风机180等。
空气质量检测装置170配置成检测空调器室内机100工作环境的空气污染参数；空气质量检测装置170可以检测空调器室内机100的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。
净化组件150由驱动装置140带动移入或移出遮蔽出风口102的净化位置，其中驱动装置140配置成在接收到空调器进入净化模式的触发信号(空气污染参数超过预设净化启动阈值的信号，该净化启动阈值根据人体对空气污染的感受进行设置，超过该净化启动阈值认定为需要对空气进行净化)后，受控地将净化组件150移动至净化位置，以利用净化组件150对室内机100的出风进行净化。在获取空调器退出净化模式的触发信号(例如空气污染参数降低至预设的净化关闭阈值)后，驱动装置140受控地带动净化组件150移出净化位置到达备用位置，以使室内机100的出风直接送出，而不经过净化。在驱动装置140受控地带动净化组件150移向更换位置时，首先受控地带动净化组件150从净化位置移出，在经过备用位置后继续移动，直至净化组件150完全移出空调器室内机100外部。
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。在净化过程中，空气质量检测装置180持续进行检测，如果出现在空气污染参数降低至预设的净化关闭阈值(可认为净化完成)后，控制驱动装置140带动净化组件150移出净化位置到达备用位置，以使室内机100的出风直接送出。如果在出现净化组件150进行净化的持续时间超过设定时 间且空气污染参数无改善的情况下，可以认定净化组件150的净化功能出现异常，此时可以控制驱动装置140将净化组件150移出净化位置到达位于空调器室内机100外部的更换位置，以供用户对净化组件150进行维护。
提示装置190可以在出现净化组件进行净化的持续时间超过设定时间且空气污染参数无改善的情况下，输出提示更换或清理净化组件的提示信息时，输出提示更换或清理净化组件150的提示信息。提示装置190可以使用以下方式输出提示信息：利用室内机100面板上设置的提示灯输出对应的提示信号；或者向空调器的遥控装置反馈提示信息，以使遥控装置的屏幕显示对应于提示信息的图标。在另一些可选实施例中，提示装置190还可以通过向空调器绑定的用户终端发送提示信息等方式输出提示信息，以便用户根据提示信息进行清洁和维护。
另外考虑到净化组件150进行净化时对风阻产生影响，室内机风机180可以配置成生成送风气流，并在将净化组件150移动至净化位置之后，提高自身的风速等级。一种提高自身的风速等级的方式为：在净化组件150移动至净化位置之后，经风速等级提高一个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。
室内机风机180另一种更优选的提高自身的风速等级的方式为：以保证室内机换热器160的温度为目标，对室内机风机180的风速进行反馈控制。例如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。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。
在空调器制热运行时，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。
以下结合本实施例的带有净化功能的空调器室内机的控制方法，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，本实施例的控制方法可以由上述介绍的带有净化功能的空调器室内机100执行，及时输出提示更换或清理净化组件150的提示信息，从而避免了随着净化组件150使用时间的增加而失效。图7是根据本发明一个实施例的带有净化功能的空调器室内机的控制方法的示意图。该控制方法一般性地可以包括：
步骤S702，检测空调器室内机100工作环境的空气污染参数；检测过程可以通过空气质量检测装置170来实现，例如可以检测空调器室内机100的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。
上述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。利用净化组件150对室内机100的出风进行净化。
步骤S704，在空气污染参数超过预设净化启动阈值的情况下，控制驱动装置140将净化组件150移动至净化位置，以利用净化组件150对室内机100的出风进行净化；设净化启动阈值根据人体对空气污染的感受进行设置，超过该净化启动阈值认定为需要对空气进行净化，从而净化可以根据空气质量自动启动。
步骤S706，持续检测空气污染参数，在出现净化组件150进行净化的持续时间超过设定时间且空气污染参数无改善的情况下，控制驱动装置140带动净化组件150移出净化位置到达位于空调器室内机100外部的更换位置，以供用户对净化组件150进行维护。如果在出现净化组件150进行净化的持续时间超过设定时间且空气污染参数无改善的情况下，可以认定净化组件150的净化功能出现异常，此时可以控制驱动装置140将净化组件150移出净化位置到达位于空调器室内机100外部的更换位置，以供用户对净化组件150进行维护。
如果在净化过程中出现在空气污染参数降低至预设的净化关闭阈值，可以控制驱动装置140带动净化组件150移出净化位置到达备用位置，以使室内机的出风直接送出。如果出现在空气污染参数降低至预设的净化关闭阈值(可认为净化完成)后，控制驱动装置140带动净化组件150移出净化位置到达备用位置，从而可以自动关闭净化，一方面提高了净化组件150的使用寿命，另外也可以节省电能的消耗。
另外考虑到净化组件150进行净化时对风阻产生影响，在将净化组件150移动至净化位置之后，在进行净化的过程中还可以：提高室内机的风机180转速的风速等级。一种室内机的风机180提高自身的风速等级的方式为：在净化组件150移动至净化位置之后，经风速等级提高一个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。
室内机风机180另一种更优选的提高自身的风速等级的方式为：以保证室内机换热器160的温度温度为目标，对室内机风机180的风速进行反馈控制。例如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。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。
在空调器制热运行时，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。
在步骤S706之后还可以输出提示更换或清理净化组件的提示信息，对用户进行提醒。提示信息可以使用以下方式输出：利用室内机100面板上设置的提示灯输出对应的提示信号；或者向空调器的遥控装置反馈提示信息，以使遥控装置的屏幕显示对应于提示信息的图标。在另一些可选实施例中，还可以通过向空调器绑定的用户终端发送提示信息等方式输出提示信息，以便用户根据提示信息进行清洁和维护。
控制驱动装置140带动净化组件150移出净化位置到达位于空调器室内机外部的更换位置的过程中可以首先控制驱动装置140带动净化组件150从净化位置移出，在经过备用位置后继续移动，直至净化组件150完全移出空调器室内机100外部。
本发明的带有净化功能的空调器室内机在其出风口处设置了可移动的净化组件，因此可以在空气质量需要改善的时候，使净化组件移动至出风口的内侧以完全遮蔽出风口，从而对将要流出空调器室内机的气流进行净化，提升室内环境的空气质量。在无需净化时，净化组件还可由驱动装置的驱动移出出风口，从而使得气流不经过净化组件直接进入室内机，从而可以根据需要开启净化功能，延长了净化组件的使用寿命。
本实施例的带有净化功能的空调器室内机的控制方法，可以自动根据空调器室内机工作环境的空气污染参数启动和关闭，并且根据净化组件150的净化状态控制驱动装置140带动净化组件150移出净化位置到达位于空调器室内机100外部的更换位置，并及时输出提示信息，便于用户更换或进行清洁，从而避免了随着净化组件150使用时间的增加而失效，杜绝二次污染，提高了用户使用体验。
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。
