具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请提供的空调净化模块积尘检测方法中所述的空调净化模块包括但不限于杀菌模块、消毒模块和过滤模块等。所述空调设有出风口，净化模块安装于空调内的与所述出风口相连通的风道内。所述出风口处安装有导风板，导风板用于改变出风口的出风方向。其中，空调还设有进风口，所述风道连通进风口和出风口。风道内还安装有风机，风机用于驱动空气从所述进风口进入所述风道并流经净化模块后从出风口送出。
发明人在对多款普通空调的净化模块积尘状态检测研究中发现，若导风板位于一定角度区间，则只要净化模块处于积尘状态，一定能够在出风口处检测到异常音。同时还发现，若导风板位于另一角度区间，则无论净化模块处于何种积尘状态，均不能够在出风口处检测不到异常音，即在该角度区间内，净化模块积尘与否均不会在出风口处形成异常音。
基于上述发现，本申请实施例提供一种空调消毒模块的积尘检测方法，如图1所示为本申请提供的空调净化模块的积尘检测方法流程示意图之一，该空调消毒模块的积尘检测方法，包括步骤：
S100，控制所述风道内的所述风机以设定转速运转，获取所述出风口在所述导风板位于第一设定位置时的第一检测声音频谱和第一参考声音频谱；
S200，根据所述第一参考声音频谱和所述第一检测声音频谱的拟合度，确定所述净化模块当前的第一积尘状态；
其中，第一设定位置对应于导风板在净化模块处于设定积尘状态时会出现异常音的位置；所述第一参考声音频谱对应于所述出风口在所述净化 装置处于所述设定积尘状态时、所述风机运行于所述设定转速时以及所述导风板位于所述第一设定位置时的声音频谱。
具体地，净化模块的积尘状态表征净化模块相对于其未积尘状态的积尘程度，可根据净化模块的积尘程度划分为更多等级的积尘状态。比如轻度积尘状态、中度积尘状态或重度积尘状态等。当净化模块达达到或接近设定积尘状态时，认为需要对净化模块进行清洗维护。
其中，风机在不同转速的情况下，第一设定位置对应的第一参考声音频谱会存在差异。在确定第一参考声音频谱时，需要在净化模块处于设定积尘状态时，控制风机以设定转速运转，然后将导风板转动至第一设定位置，对出风口处的声音频谱进行采集，将采集到的声音频谱作为第一参考声音频谱。
当需要对空调净化模块的积尘状态进行检测时，控制风机以上述设定转速运转，并控制导风板转动至第一设定位置，采集出风口处的声音频谱，该声音频谱为第一检测声音频谱。检测第一检测声音频谱与第一参考声音频谱的拟合度，拟合度越高，则表明净化模块当前的积尘状态越接近设定积尘状态。
本申请提供的空调净化模块的积尘检测方法，通过将实际检测到的出风口在导风板处于第一设定位置时的第一检测声音频谱与净化模块处于设定积尘状态下时出风口在导风板处于第一设定位置时的第一参考声音频谱进行拟合度分析，根据二者之间的拟合度可准确的确定净化模块的积尘状态。
具体地，步骤S200中所述的，根据第一参考声音频谱和所述第一检测声音频谱的拟合度确定所述净化模块的第一积尘状态，具体包括：
S210，若第一设定拟合度＜所述拟合度＜第二设定拟合度，则判定所述净化模块处于中度积尘状态；
S220，若所述拟合度＞第二设定拟合度，则判定所述净化模块处于重度积尘状态。
例如，第一设定拟合度为60％，第二设定拟合度为80％。当60％＜拟合度≤80％时，判断净化模块处于中度积尘状态，用户可根据个人需求确定是否清洗净化模块。当拟合度＞80％时，判断净化模块处于重度积尘状 态。当然，还可设置更多级别的积尘状态，根据多个级别的积尘状态确定与每一级别的积尘状态对应的设定的拟合度，实现对积尘状态的更精细判断。
进一步地，本申请实施例提供的空调净化模块的积尘检测方法，还包括：
在风机运行于不同转速情况下，分别对所述出风口在所述导风板处于所述第一设定位置时的声音频谱进行采集；
将采集到的所述声音频谱进行线性拟合，获得所述风机转速与所述第一参考声音频谱的关系曲线，根据所述关系曲线获取当前转速下的所述第一参考声音频谱。
具体地，在净化模块处于设定积尘状态下，在风机处于不同转速情况下，以及在导风板处于第一设定位置时，对出风口处的声音频谱进行采集。将采集到的不同转速对应的第一参考声音频谱进行线性拟合，得到风机转速与第一参考声音频谱的关系曲线。根据该关系曲线可获得风机任一大小转速所对应的第一参考声音频谱。如此，在对净化模块进行积尘状态检测时，无需配合调节风机的转速即可实现对净化模块的积尘状态的检测。不影响用户的正常使用，只要风机处于运行状态均可进行净化模块积尘状态的检测。避免设定转速与空调当前转速差异较大，而使检测影响用户的送风体验。
基于上述发现，如图2所示为本申请提供的空调净化模块的积尘检测方法的流程示意图之二，本申请实施例还提供的空调净化模块的积尘检测方法，还包括：
S300，控制所述风机以所述设定转速运转，获取所述出风口在所述导风板位于第二设定位置时的第二检测声音频谱；
S400，根据所述第一检测声音频谱和所述第二检测声音频谱的偏离度确定所述净化模块当前的第二积尘状态；
S500，将所述第一积尘状态和所述第二积尘状态中积尘程度高的一者确定为所述净化模块当前的实际积尘状态；
其中，所述第二设定位置对应于所述导风板在所述净化模块处于任一积尘状态时均不会出现异常音的位置。
具体地，当需要对空调净化模块的积尘状态进行检测时，控制风机以上述设定转速运转。控制导风板转动至第一设定位置，采集出风口处的第一检测声音频谱；以及，控制导风板转动至第二设定位置，采集出风口处的第二检测声音频谱。第一检测声音频谱和第二检测声音频谱可以任一顺序进行先后检测。检测第一检测声音频谱与第一参考声音频谱的偏离度，偏离度越低，则表明净化模块当前的积尘状态越接近设定积尘状态。
本实施例同时根据第一检测声音频谱与第一参考声音频谱的拟合度以及第二检测声音频谱与第一检测声音频谱的偏离度判断净化模块的积尘状态，能够进一步提高积尘状态判断的准确性。
具体地，步骤S400中所述的，根据所述第一检测声音频谱和所述第二检测声音频谱的偏离度确定所述净化模块当前的第二积尘状态，具体包括：
S410，若第一设定偏离度≤所述偏离度＜第二设定偏离度，则判定所述净化模块处于中度积尘状态；
S420，若0＜所述偏离度＜第一设定偏离度，则判定所述净化模块处于重度积尘状态。
例如，第一设定偏离度为30％，第二设定偏离度为70％。当30％≤偏离度＜70％时，判断净化模块处于中度积尘状态。当偏离度＜30％时，判断净化模块处于重度积尘状态。当然，还可设置更多级别的积尘状态，根据多个级别的积尘状态确定与每一级别的积尘状态对应的设定的偏离度，实现对积尘状态的更精细判断。
本申请实施例中，导风板为横向导风板。横向导风板可相对出风口的中轴线上下摆动以实现上下方向送风角度的调节。如图4所示为导风板与出风口的中轴线的夹角示意图，图4中的O-O为出风口的中轴线，出风口的出风方向与中轴线方向平行，箭头方向是指出风口的出风方向，图4示意了导风板相对中轴线向上倾斜且与中轴线的夹角为55°、65°和90°的状态。在90°状态下，导风板处于关闭出风口的状态。其中，导风板相对中轴线的夹角是指导风板相对中轴线的最小夹角。
在对某一款空调的净化模块积尘状态检测的实验数据显示，当横向导风板相对出风口的中轴线向上倾斜，且其与出风口的中轴线的夹角在0° 到55°之间时，以及当横向导风板相对出风口的中轴线向下倾斜时，在净化模块干净状态下和积尘状态下，出风口处的频谱曲线均有波动且无法区分。
当横向导风板相对出风口的中轴线向上倾斜，且其与出风口的中轴线的夹角在55°到65°之间时，在净化模块干净状态下，出风口处的频谱曲线无波动；在净化模块积尘状态下，出风口处的频谱曲线有波动。且净化模块干净状态下的频谱曲线与净化模块积尘状态下的频谱曲线差异大。将第一设定位置设置为其与出风口的中轴线的夹角为55°到65°之间的某一角度时，能够根据第一检测声音频谱分辨净化模块是否处于积尘状态。
因此，本实施例中，导风板位于第一设定位置时，导风板相对出风口的中轴线向上倾斜，且导风板与出风口的中轴线的夹角为θ，55°＜θ≤65°。其中，θ为60°时，第一检测声音频谱与第一参考声音频谱的差异较大，对净化模块的第一积尘状态判断具有较高的准确性。
当横向导风板相对出风口的中轴线向上倾斜，且其与出风口的中轴线的夹角在65°到90°之间时，在净化模块干净状态和积尘状态下，出风口处的频谱曲线均无波动。因此，导风板位于第二设定位置时，导风板相对出风口的中轴线向上倾斜，且导风板与出风口的中轴线的夹角为β，65°＜β＜90°。例如，β为65°、80°或90°。以导风板位于第二设定位置时的第二检测声音频谱作为基准频谱，根据导风板位于第一设定位置时的第一检测声音频谱相对该基准频谱的偏离度来确定净化模块的第二积尘状态。
需要说明的是，根据空调结构的不同，θ和β的大小可能会存在差异。在本申请实施例提供的空调净化模块的积尘检测方法具体应用于某一特定空调时，可以根据净化模块处于积尘状态和干净状态下以及导风板处于不同角度时，实际检测的出风口的声音频谱来确定θ和β的大小。

其中，控制单元302用于根据第一参考声音频谱和所述第一检测声音频谱的拟合度确定所述净化模块当前的第一积尘状态，具体包括：
