技术领域
本申请涉及空调器技术领域，尤其涉及一种滤网控制方法、空调器及计算机可读存储介质。
背景技术
目前的空调器，室内空气与室内换热器进行热交换之前，首先需要经过滤网进行过滤，避免空气中的灰尘或杂质进入室内换热器内部，一方面提高空调内机的工作稳定性，另一方面室内机吹出风的空气质量高，因此，会在空调器上安装滤网。
随着空调器的运行，滤网上的灰尘逐渐累积，为了清洁及健康，需要定期清洗滤网。滤网的清洗方式包括：手工清洗以及自动清洗。手工清洗需要拆开空调器的面板，拿出滤网清洗，清洗完成后再装上，操作过程较为繁琐，而采用自动清洗滤网的方式空调器，在自动清扫滤网时，滤网灰尘可以通过空调器自带的清扫机构清除，清扫机构通过转动带动滤网卷动，将滤网上面的灰尘扫到集尘盒，从而实现清扫的目的。
但是，采用自动清洗滤网的方式空调器，往往直接执行清扫过程，即通过清扫机构通过转动带动滤网卷动，进行滤网的清扫，若当前滤网与清扫机构之间配合不良，则会降低滤网的清扫效率，例如，清扫机构带动滤网卷动时，由于滤网与清扫机构之间配合不良，而导致滤网转动速度比正常情况下慢，可能会导致滤网清扫不完全。

此外，为实现上述目的，本申请还提供一种计算机可读存储介质，所述计算机可读存储介质上存储有计算机可读指令，所述计算机可读指令被处理器执行时实现上述中任一项所述的滤网控制方法的步骤。

应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
如图1所示，图1是本申请实施例方案涉及的硬件运行环境中空调器的结构示意图。
如图1所示，该空调器可以包括：处理器1001，例如CPU，网络接口1004，用户接口1003，存储器1005，通信总线1002。其中，通信总线1002用于实现这些组件之间的连接通信。用户接口1003可以包括显示屏（Display）、输入单元比如键盘（Keyboard），可选用户接口1003还可以包括标准的有线接口、无线接口。网络接口1004可选的可以包括标准的有线接口、无线接口（如WI-FI接口）。存储器1005可以是高速RAM存储器，也可以是稳定的存储器（non-volatile memory），例如磁盘存储器。存储器1005可选的还可以是独立于前述处理器1001的存储装置。
可选地，空调器还可以包括摄像头、RF（Radio Frequency，射频）电路，传感器、音频电路、WiFi模块等等。其中，传感器比如光传感器、运动传感器以及其他传感器。当然，空调器还可配置陀螺仪、气压计、湿度计、温度计、红外线传感器等其他传感器，在此不再赘述。
本领域技术人员可以理解，图1中示出的空调器结构并不构成对空调器的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
如图1所示，作为一种计算机存储介质的存储器1005中可以包括操作系统、网络通信模块、用户接口模块以及计算机可读指令。
在图1所示的空调器中，网络接口1004主要用于连接后台服务器，与后台服务器进行数据通信；用户接口1003主要用于连接客户端（用户端），与客户端进行数据通信；而处理器1001可以用于调用存储器1005中存储的计算机可读指令。
在本实施例中，空调器包括：存储器1005、处理器1001及存储在所述存储器1005上并可在所述处理器1001上运行的计算机可读指令，其中，处理器1001调用存储器1005中存储的计算机可读指令时，并执行本申请各个实施例中滤网控制方法的步骤。
本申请还提供一种滤网控制方法，参照图2及图3，图2为本申请滤网控制方法第一实施例的流程示意图；图3为本申请空调器的滤网清扫过程中各个阶段滤网位置的结构示意图，其中，图（a）为滤网处于初始位置的结构示意图，图（b）为滤网处于中间位置的结构示意图，图（c）为滤网处于最大移送位置的结构示意图。
在本实施例中，该滤网控制方法应用于设有滤网10的空调器，该空调器设有用于清扫滤网10的毛刷30、用于控制毛刷30的步进电机（未示出）以及与所述毛刷30配合的胶条40。
其中，滤网10的两侧以及毛刷30的两侧均设有齿轮，滤网10两侧的齿轮与毛刷30两侧的齿轮相互配合，以通过毛刷30带动滤网10。
图（a）中，滤网10处于初始位置时，该滤网10按压检测模块20（检测开关），并使检测开关变形至最小形态；图（b）中，在步进电机正向或反向转动时，该步进电机通过毛刷30带动滤网10卷动至该中间位置；图（c）中，在滤网10的清洗过程中，步进电机正向转动至最大移送角度时，滤网10处于最大移送位置，若此时该步进电机继续正向转动，则会造成滤网10脱落等情况，导致滤网10无法正常复位及恢复至初始位置。
在清扫滤网时，步进电机正向转动，毛刷30上的齿轮带动滤网10上的齿轮，以移送滤网10，使滤网10有图（a）中的初始位置逐渐运动至图（b）中的位置，最后运动至图（c）中的最大移送位置，而后，步进电机反向转动，毛刷30带动滤网10再向相反方向转动（回送），使滤网10恢复到（a）中的初始位置，此时一次清扫过程完成。
在移送以及回送过程中胶条40均正向转动，毛刷30上面的细毛会顶到滤网10的网孔中，将滤网10上面附着的灰尘顶出，同时胶条40的转动将顶出的灰尘刮到集尘盒里，从而达到清扫过滤网10的目的。其中，正向转动是指逆时针转动，反向转动是指顺时针转动，即步进电机与胶条40在正向转动时均按照顺时针转动，步进电机与胶条40在反向转动时均按照逆时针转动。
进一步地，该空调器还设有用于检测滤网10的检测模块20，该检测模块20设置于处于初始位置的滤网10远离毛刷30的一端，该检测模块20可以为接触传感器、压力传感器或者检测开关。
若该检测模块20为接触传感器，则在该滤网10接触到该接触传感器时，该触摸传感器检测到接触信号，并将该接触信号发送至空调器的控制器，控制器可根据该接触信号判定检测模块20（接触传感器）检测到滤网10。
若该检测模块20为压力传感器，则在该滤网10按压该压力传感器时，该压力传感器检测到的压力信号变大，该压力传感器可实时发送其检测到的压力值至空调器的控制器，控制器可根据该压力值判断检测模块20（压力传感器）是否检测到滤网10，例如，可设定一压力阈值，在该压力传感器检测到的压力值大于该压力阈值时，判定检测模块20（压力传感器）检测到滤网10。
若检测模块20为检测开关，所述滤网10按压所述检测开关时，触发按压信号；在接收到所述检测模块20发送的按压信号时，判定所述检测模块20检测到所述滤网10。该检测开关为弹性开关，在滤网10逐渐按压该检测开关时，由于滤网10的压力逐渐增大，使得按压开关逐渐被压紧，进而使得滤网10能够完全回到初始位置，进而实现滤网10的完全复位。在本实施例中，为减少空调器的成本，该检测模块20为检测开关。
本申请的滤网10控制方法包括滤网10位置确认、检测模块20确认的过程，滤网10清扫的过程，以及滤网10位置修正的过程，其中，本实施例为滤网10清扫的过程。
该滤网控制方法包括以下步骤：
步骤S110，循环执行对所述滤网的移送操作以及对所述滤网的回送操作，并更新所述回送操作的回送次数；
在本实施例中，在清扫滤网10时，先循环执行对滤网10的移送操作以及对滤网10的回送操作，并在执行回送操作时更新回送操作的回送次数。具体的执行顺序为：移送操作-回送操作-移送操作-回送操作…。在执行移送操作时，步进电机正向转动，带动毛刷30正向转动，从而通过毛刷30移送滤网10，此时滤网10的运动方向为初始位置至清扫最大位置的方向，如图3所示，在该步进电机正向转动时，步进电机带动毛刷30逆时针转动；在执行回送操作时，步进电机反向转动，带动毛刷30反向转动，从而通过毛刷30回送滤网10，此时滤网10的运动方向为清扫最大位置至初始位置的方向，如图3所示，在该步进电机反向转动时，步进电机带动毛刷30顺时针转动。
具体地，移送操作包括基于第一预设角度控制步进电机正向转动，以通过所述毛刷30移送所述滤网10；所述回送操作包括基于第二预设角度控制所述步进电机反向转动，以通过所述毛刷30回送所述滤网10；其中，所述第一预设角度大于所述第二预设角度。
第一预设角度为该步进电机的转轴的转动角度，该转轴可以毛刷30同步转动，即转轴转动第一预设角度，该毛刷30同时转动第一预设角度，在其他实施例中，该转轴可以毛刷30异步转动，即转轴的转动角度与毛刷30的转动角度存在一比例关系。
第一预设角度大于第二预设角度，其中，第一预设角度可设置为130度、150度，相应的，该第二预设角度可设置为90度、110度等。
通过设置第一预设角度大于第二预设角度，使得每次滤网10的移送量大于回送量，进而避免滤网10再次回复初始位置。
步骤S120，在更新后的回送次数达到第一预设阈值、且所述回送操作完成时，控制所述步进电机正向转动，并控制所述胶条正向转动；
其中，第一预设阈值可以根据回送次数的初始值进行合理设置，例如，在回送次数的初始值为0时，该第一预设阈值可设置为3。
在本实施例中，在更新后的回送次数达到第一预设阈值、且回送操作完成时，经过多次对滤网10的移送及回送，使得滤网10以及毛刷30均能够完全活动开，即滤网10的齿轮与毛刷30的齿轮之间的配合良好，在清扫滤网10时不会存在滤网10运动速度与步进电机的转动速度不匹配的问题，此时，控制步进电机正向转动，并控制胶条40正向转动，通过步进电机带动毛刷30正向转动，而毛刷30又带动滤网10正向卷动，使得毛刷30上面的细毛会顶到滤网10的网孔中，将滤网10上面附着的灰尘顶出，胶条40的转动将顶出的灰尘刮到集尘盒里，从而达到清扫过滤网10的目的。
步骤S130，在检测到所述步进电机的正向转动角度达到最大移送角度时，控制所述步进电机反向转动；
在本实施例中，若检测到所述步进电机的正向转动角度达到最大移送角度，则控制所述步进电机反向转动，通过步进电机带动毛刷30反向转动，而毛刷30又带动滤网10反向卷动，使得毛刷30上面的细毛会顶到滤网10的网孔中，将滤网10上面附着的灰尘顶出，胶条40的转动将顶出的灰尘刮到集尘盒里，从而达到清扫过滤网10的目的。
其中，该最大移送角度为滤网10从初始位置移动至最大清扫位置时步进电机的转动角度-第一预设阈值*（第一预设角度与第二预设角度之差），以确保该滤网10的卷动量不会过量，避免滤网10脱落等情况而导致无法回送滤网10。
步骤S140，在检测到所述步进电机的反向转动角度达到最大回送角度时，控制所述步进电机停止运行。
在本实施例中，在步进电机的反向转动角度达到最大回送角度时，该滤网10已复位，即当前滤网10处于初始位置，因此，控制步进电机停止运行，进而完成对滤网10的清扫。
进一步地，在一实施例中，在步骤S140之后，该滤网控制方法还包括：
控制所述胶条反向转动，在所述胶条反向转动的持续时长达到预设时长时，控制所述胶条停止转动，并重置所述回送次数。
通过在步进电机停止时，控制胶条40反向转动，并在反向转动的持续时长达到预设时长时，停止胶条40的转动，能够确保清扫的灰尘全部刮到集尘盒里，通过重置回送次数，以便于后续清扫操作的顺利执行。
重置回送次数，是指将该回送次数设置为对应的初始值，该初始值可以为任一常数，例如在该初始值为0时，重置该回送次数是指将该回送次数设置为0。在其他实施例中，还可以在空调器上电后至更新所述回送操作的回送次数的任意时刻重置该回送次数。
本实施例提出的滤网控制方法，通过循环执行对所述滤网的移送操作以及对所述滤网的回送操作，并更新所述回送操作的回送次数，接着在更新后的回送次数达到第一预设阈值、且所述回送操作完成时，控制所述步进电机正向转动，并控制所述胶条正向转动，而后在检测到所述步进电机的正向转动角度达到最大移送角度时，控制所述步进电机反向转动，然后在检测到所述步进电机的反向转动角度达到最大回送角度时，控制所述步进电机停止运行，通过循环执行移送操作以及回送操作，使得滤网以及毛刷均能够完全活动开，即滤网的齿轮与毛刷的齿轮之间的配合良好，在清扫滤网时不会存在滤网运动速度与步进电机的转动速度不匹配、而导致滤网卷动速度较慢的情况，提高了滤网的清扫效率。并且通过控制步进电机转动至最大移送角度保证滤网的完全清扫，通过控制步进电机转动至最大回送角度，以确保在清扫完成时滤网恢复至初始位置，便于后续滤网的清扫，进一步提高了滤网的清扫效率。

基于第一实施例，提出本申请滤网控制方法的第七实施例，在本实施例中，
步骤S300，在空调器上电运行或者检测到滤网清扫指令时，若当前所述检测模块检测到所述滤网，则基于第四预设角度控制所述步进电机正向转动，以通过毛刷移送所述滤网；
在本实施例中，若空调器上电运行或者检测到滤网清扫指令，则通过检测模块20的检测信号确定检测模块20是否检测到滤网10，若当前该检测模块20检测到了该滤网10，则确定该滤网10当前正在按压该检测模块20，但并不能保证滤网10已完全复位，且不能保证清扫机构是否能正常运行，因此，基于第四预设角度控制步进电机正向转动，通过步进电机正向转动第四预设角度，带动毛刷30同时转动第四预设角度，以通过毛刷30移送该滤网10。

其中，第五预设角度可以根据预设角度进行合理设置，预设角度值为清扫机构以及检测模块均正常时，检测开关由被滤网10完全按下至与滤网10完全分离时，步进电机正向转动的角度，该第五预设角度大于该预设角度值。例如，该第五预设角度可设置为120度。
进一步地，在一实施例中，该滤网控制方法还包括：若在基于第四预设角度控制所述步进电机正向转动，以通过毛刷移送所述滤网之后，接收到开关机指令，则在控制所述步进电机停止运行后，执行所述开关机指令对应的操作。
本实施例提出的滤网控制方法，通过在检测到滤网清扫指令时，若所述检测模块未检测到所述滤网，则控制所述步进电机反向转动，以通过所述毛刷回送所述滤网，接着在所述步进电机反向转动的过程中，实时确定所述检测模块是否检测到所述滤网，而后在确定所述检测模块检测到所述滤网时，基于第五预设角度控制所述步进电机反向转动，然后在所述步进电机的反向转动角度达到所述第五预设角度，控制所述步进电机停止运行，能够通过回送滤网确定清扫机构以及滤网是否存在故障，在不存在故障即检测模块20检测到所述滤网时，继续回送滤网以使滤网复位，进而能够确保滤网完全复位，进一步提高了后续滤网的清扫效率。
基于第九实施例，提出本申请滤网控制方法的第十实施例，在本实施例中，在步骤S360之后，该滤网控制方法还包括：
步骤S390，在确定所述检测模块未检测到所述滤网、且所述步进电机的反向转动角度达到最大回送角度时，更新所述滤网的第三检测次数；
步骤S400，在更新后的第三检测次数大于第五预设阈值时，控制所述步进电机停止运行，并输出第四故障信息。
在本实施例中，在该步进电机反向转动的过程中，实时确定该检测模块2020是否检测到滤网10，若确定所述检测模块20未检测到所述滤网10、且所述步进电机的反向转动角度达到最大回送角度，即步进电机的反向转动角度达到最大回送角度时检测模块20仍未检测到滤网10，则更新滤网10的第三检测次数，更新后的第三检测次数大于第五预设阈值时，则表明当前该滤网10没有随着毛刷30的转动而运动、或者运动量很小，可能存在滤网10卡死、毛刷30与滤网10之间的齿轮啮合故障，或者，检测模块20出现故障导致该检测模块20识别出错，此时，控制所述步进电机停止运行，并输出第四故障信息，具体地，可在空调器的显示屏显示该第四故障信息，或者若该空调器当前已接入网络，则可将该第四故障信息发送至预设终端，例如用户终端或者维修人员的终端。
其中，第四故障信息包括检测模块故障信息、滤网故障信息以及所述毛刷与所述滤网之间的齿轮啮合故障信息。其中，第五预设阈值可根据第二检测次数的初始值进行合理设置，例如，在第三检测次数的初始值为0时，该第五预设阈值可设置为3。
进一步地，在一实施例中，在步骤S390之后，该滤网控制方法还包括：在更新后的第三检测次数小于或等于第五预设阈值时，继续执行控制所述步进电机反向转动，以通过所述毛刷回送所述滤网的步骤。
在本实施例中，若更新后的第三检测次数小于或等于第五预设阈值，则继续执行步骤S380，以再次回送滤网10，通过多次回送尝试通过毛刷30带动滤网10。
进一步地，又一实施例中，该滤网控制方法还包括：在所述空调器上电、或者输出所述第四故障信息时，重置所述第三检测次数。
在本实施例中，可以在空调器上电时、或者在输出第四故障信息时，重置该第三检测次数，即将该第三检测次数设置为对应的初始值，该初始值可以为任一常数，例如在该初始值为0时，重置该第三检测次数是指将该第三检测次数设置为0。在其他实施例中，还可以在空调器上电后至更新第二检测次数之前的任意时刻重置第三检测次数。
进一步地，再一实施例中，该滤网控制方法还包括：若在基于第四预设角度控制所述步进电机正向转动，以通过毛刷移送所述滤网之后，接收到开关机指令，则在输出第四故障信息后，执行所述开关机指令对应的操作。
本实施例提出的滤网控制方法，通过在确定所述检测模块未检测到所述滤网、且所述步进电机的反向转动角度达到最大回送角度时，更新所述滤网的第三检测次数，接着在更新后的第三检测次数大于第三预设阈值时，控制所述步进电机停止运行，并输出第四故障信息，若多次控制步进电机反向转动时检测模块均检测不到滤网，则能够确定该空调器当前存在故障，进而输出第四故障信息，以便于维护人员根据该第四故障信息对该空调器进行维护，进而提高了用户体验。
此外，本申请实施例还提出一种计算机可读存储介质，所述计算机可读存储介质上存储有计算机可读指令，所述计算机可读指令被处理器执行时实现本申请各个实施例中滤网控制方法的步骤。
