S504：基于室内机的换热器220的盘管温度、第一预设温度阈值、第二预设温度阈值调节空调器100的压缩机170的频率和风机120的转速，其中第一预设温度阈值大于第二预设温度阈值。
本发明的空调器100的控制方法提出当空调器100处于制冷状态时，基于空调器100的室内机所处的周围环境是否存在用户和室内机的风机120的转速或者基于空调器100是否接收到自然风控制指令调节空调器100的送风模式，使得空调器100在制冷状态时的送风模式与用户、风机120转速、控制指令相关联，使得空调器100的控制更精准；同时，本发明的空调器100的控制方法还基于室内机的换热器220的盘管温度、第一预设温度阈值、第二预设温度阈值来对压缩机170的频率和室内机的风机120的转速进行调节，使得整个空调器100的控制更为精准，更精细化。空调器100的送风模式中至少限定有风机120的转速。
如图3所示，在出风口113处还设置有摆叶组件140，摆叶组件140包括多个横摆叶160和多个竖摆叶150。多个横摆叶160水平延伸设置，用于调节上下方向出风。多个竖摆叶150竖向延伸设置，用于调节左右方向出风。步骤S502包括：在检测到室内机所处的周围环境存在用户且风机120的转速大于预设转速阈值时或者在空调器100接收到自然风控制指令时，控制空调器100以自然风模式送风，其中自然风模式中，随机间歇调整风机120的转速，自由摆动多个横摆叶160，自由摆动多个竖摆叶150。通常在空调器100以强风送冷时会出现空调器100直吹人体的情况，特别是当用户正对着空调器100时，冷风会对人体部位尤其是人体面部直吹，让用户产生过冷感。本发明的空调器100的控制方法提出当空调器100处于制冷状态时，通过将空调器100设置成在检测到空调器100的室内机所处的周围环境存在用户且室内机的风机120的转速大于预设转速阈值时或者在空调器100接收到自然 风控制指令时，控制空调器100以自然风模式送风，使得空调器100在满足一定条件时自动、强制开启自然风送风模式，避免冷风对人体部位的直吹所产生的过冷感，提高用户的吹风感受；同时，本发明实施例的空调器100的控制方法的自然风模式是通过对风机120、横摆叶160、竖摆叶150分别进行不同的控制来实现，可以使吹风方式更接近自然风，提高用户吹风感受；空调器100整体实现了智能控制，不仅节省了能源，而且满足了用户需求，提高了用户舒适性体验。
继续参见图3，横摆叶160由摆叶本体161、连杆162、长转轴和短转轴组成。长转轴嵌入风道骨架130，可随连杆162的拉动来上下转动。短转轴嵌在连杆162内，可随连杆162的转动来转动。在摆叶本体161上还随机设定有多个凸起163，凸起163优选地高度2-4mm，成椭圆状，短轴长2-4mm，长轴长4-6mm，主要作用是对出风形成不同方向的分散。多个横摆叶160可同步枢转以调节出风的上下方向。多个竖摆叶150可同步枢转以调节出风的左右方向。在一些实施例中，每个横摆叶160沿左右方向依次形成有多个弯折结构；每个竖摆叶150沿上下方向依次形成有多个弯折结构。例如，每个横摆叶160沿左右方向呈波浪形，每个竖摆叶150沿上下方向呈波浪形，来对风形成分散。多个横摆叶160在上下方向的最大摆动角度的取值范围是20°-160°。多个竖摆叶150在左右方向的最大摆动角度的取值范围是0°-180°。本发明实施例的空调器100通过对横摆叶160和竖摆叶150的结构进行改进，将横摆叶160设置成整体呈波浪形且具有多个凸起163，同时将竖摆叶150设置成整体呈波浪形，并且对风机120的转速随机间歇调整，以及对横摆叶160、竖摆叶150分别设置成自由摆动可以使吹风方式更接近自然风，提高用户吹风感受。
在一些实施例中，随机间歇调整风机120的转速的步骤包括：
以随机方式生成风机120的多个连续的转速调节周期，其中每个转速调节周期内限定有相应的预设转速变化方向、预设转速变化值和预设维持时间；
控制风机120的转速按照一个转速调节周期的预设转速变化方向调整预设转速变化值并保持预设维持时间，之后进行下一个转速调节周期。
本发明的空调器100的控制方法通过以随机方式生成风机120的多个连续的转速调节周期，可以实现风机120的转速的无规律增减，形成自由送风， 模拟自然界达到突涌式送风的效果。空调器100还包括：第一随机生成装置(图中未示出)，第一随机生成装置配置成以随机方式生成风机120的多个连续的转速调节周期，其中每个转速调节周期内限定有相应的预设转速变化方向、预设转速变化值和预设维持时间。可以根据随机函数生成多个连续的转速调节周期的随机量；也可以利用空调器100运行中产生的随机信号作为随机函数的生成种子，进而生成转速调节周期的随机量；还可以是直接使用空调器100中的随机信号作为信号源，进而生成转速调节周期的随机量。例如，可将转速检测装置获取的信号的最后几位数字进行处理后，生成转速调节周期的随机量。预设转速变化方向包括增速、减速；预设转速变化值可以依照需要设定，例如为10r/min、15r/min、20r/min、30r/min，预设维持时间可以依照需要设定，例如为10s、30s、1min、2min、5min。以空调器100内存储有5个的不同的转速调节周期a、b、c、d、e，随机生成3个转速调节周期，初始转速为900r/min为例，其中转速调节周期a中限定有：增速、预设转速变化值为10r/min、预设维持时间为30s；转速调节周期b中限定有：减速、预设转速变化值为20r/min、预设维持时间为10s；转速调节周期c中限定有：增速、预设转速变化值为20r/min、预设维持时间为1min；转速调节周期d中限定有：减速、预设转速变化值为30r/min、预设维持时间为1min；转速调节周期e中限定有：增速、预设转速变化值为30r/min、预设维持时间为1min。风机120的转速可以是匀速变化，也可以是变速变化。假定第一随机生成装置随机生成的多个连续的转速调节周期包括转速调节周期a、转速调节周期a、转速调节周期b，意味着风机120的转速先增速10r/min至910r/min，以910r/min保持运行30s，之后增速10r/min至920r/min，以920r/min保持30s，再减速20r/min至900r/min，以900r/min保持10s。又例如，第一随机生成装置随机生成的连续的转速调节周期包括转速调节周期b、转速调节周期c、转速调节周期e。再例如，第一随机生成装置随机生成的连续的转速调节周期包括转速调节周期c、转速调节周期a、转速调节周期e。在一些实施例中，以随机方式生成的多个连续的转速调节周期满足：风机120的转速的最大增速值小于等于预设增速阈值，风机120的转速的最大减速值小于等于预设减速阈值。预设增速阈值用于限定出风机120的转速的最大增速范围，预设减速阈值用于限定出风机120的转速的最大减速范围。预设增速阈值和预设减速阈值可以相同，也可以不同。换句话说，风机120的转速的 取值范围是初始转速与预设减速阈值的差-初始转速与预设增速阈值的和。依然以风机120的初始转速为900r/min为例，假设预设增速阈值和预设减速阈值均为30r/min，则风机120的转速的取值范围是870r/min-930r/min。此时，第一随机生成装置在随机生成多个连续的转速变化周期时，还需要将预设增速阈值和预设减速阈值考虑到，这样可以将例如多个连续的转速调节周期为转速调节周期c、转速调节周期e、转速调节周期d的情形排除在外，使得风机120的转速的变化不至于过大，而是在一定范围内无规律增减，使用户的吹风体验更好。
在一些实施例中，自由摆动多个横摆叶160的步骤包括：以随机方式生成多个横摆叶160的摆动参数，多个横摆叶160的摆动参数包括摆动方向、摆动角度、摆动速度中的一种或多种，并基于多个横摆叶160的摆动参数对多个横摆叶160进行控制。

空调器100还包括：第三随机生成装置，第三随机生成装置配置成：以随机方式生成多个竖摆叶150的摆动参数。摆动方向包括向左摆动和向右摆动，摆动角度例如2°、5°、10°、20°、30°，摆动速度例如2°/min、5°/min、10°/min、15°/min、20°/min。具体地，自由摆动多个竖摆叶150可以参考前述的随机间歇风机120的转速部分的步骤，例如包括：以随机方式生成竖摆叶150的多个连续的摆动调节周期，其中每个摆动调节周期内限定有相应的预设摆动方向、预设摆动角度和预设摆动速度；控制竖摆叶150按照一个摆动调节周期进行摆动，之后进行下一个摆动调节周期。以空调器100内存储有5个的不同的竖摆叶150摆动调节周期A’、B’、C’、D’、E’，随机生成3个摆动调节周期，初始竖摆叶150的摆动角度为60°为例，其中摆动调节周期A’中限定有：向左摆动、预设摆动角度为2°、预设摆动速度为2°/min；摆动调节周期B’中限定有：向左摆动、预设摆动角度为10°、预设摆动速度为5°/min；摆动调节周期C’中限定有：向右摆动、预设摆动角度为20°、预设摆动速度为5°/min；摆动调节周期D’中限定有：向右摆动、预设摆动角度为2°、预设摆动速度为2°/min；摆动调节周期E’中限定有：向右摆动、预设摆动角度为10°、预设摆动速度为10°/min。假定第三随机生成装置随机生成的连续的摆动调节周期包括摆动调节周期A’、摆动调节周期A’、摆动调节周期D’，意味着竖摆叶150先以2°/min向左摆动2°至摆动角度为62°，之后以2°/min向左摆动2°至摆动角度为64°，再以2°/min向右摆动2°至摆动角度为62°。又例如，第三随机生成装置随机生成的连续的摆动调节周期包括摆动调节周期A’、摆动调节周期B’、摆动调节周期E’。再例如，第三随机生成装置随机生成的连续的摆动调节周期包括摆动调节周期E’、摆动调节周期B’、摆动调节周期D’。
在一些实施例中，步骤S502中，空调器100接收到自然风控制指令时，控制空调器100以自然风模式送风。室内机还包括接收装置190，用于接收自然风控制指令。例如，空调器100对应的遥控器上设有用于触发自然风控制指令的自然风按键，用户通过按压或点击该自然风按键触发自然风控制指令，在检测到该自然风按键触发的自然风控制指令时，遥控器等控制端将该自然风控制指令发送至接收装置190，在接收装置190收到该自然风控制指令后，控制装置200控制空调器100以自然风模式送风。
在一些实施例中，步骤S502中，检测到空调器100的室内机所处的周围环境存在用户且室内机的风机120的转速大于预设转速阈值时，控制空调器100以自然风模式送风。室内机还包括检测装置180，配置成检测室内机所处的周围环境是否存在用户以及检测风机120的转速。检测装置180可以是包括人体检测装置和转速检测装置。人体检测装置可以是智能人体/人脸感应装置。
步骤S502中，检测室内机所处的周围环境是否存在用户以及检测风机120的转速是否大于预设转速阈值的步骤包括：
检测室内机所处的周围环境是否存在用户；
若是，判断风机120的转速与预设转速阈值的大小。
本发明的控制方法先检测室内机所处的周围环境是否存在用户，仅在当室内机所处的周围环境存在用户时，再判断风机120的转速与预设转速阈值的大小，可以使整个控制逻辑更精简。转速与预设转速阈值的大小判断可以是通过精准获取风机120的转速来与预设转速阈值来确定。例如，预设转速阈值为800r/min，当获取的风机120的转速为900r/min，则认为转速大于预设转速阈值，当获取的风机120的转速为760r/min，则认为转速小于预设转速阈值。转速与预设转速阈值的大小判断还可以是通过风机120所处的风速档位来粗略估算。通常，空调器100具有三个风速档位，低风档、中风档和高风档。当风速档位为中风档或低风档时，可以认为转速小于预设转速阈值，而在风速档位为高风档时，可以认为转速大于预设转速阈值。
在一些实施例中，检测室内机所处的周围环境是否存在用户的步骤包括：
获取室内机前预定区域内的周围环境的图像；
判断图像中是否存在人脸图像；
若是，确定室内机所处的周围环境存在用户。
预定区域例如是以整机平面为基准的160°角度范围内的区域，再例如是受室内机的送风模式影响较大的区域。
在一些实施例中，在检测室内机所处的周围环境是否存在用户的步骤之前还包括：
判断空调器100是否首次进入制冷状态；
若是，获取压缩机170的多个排气温度；
判断相邻的两个排气温度的差值是否小于等于预设温差阈值；
在确定差值小于等于预设温差阈值后，判断室内机所处的周围环境是否存在用户。
空调器100首次进入制冷状态可包括两种情形，一种是空调器100初次上电运行并进入制冷状态，一种是空调器100非初次上电运行但是首次进入制冷状态或者首次由制热状态或送风状态切换为制冷状态。本发明的空调器100的控制方法在检测到的排气温度进入稳定状态后，再检测室内机所处的周围环境是否存在用户，预设温差阈值例如可以为1℃、2℃、3℃。
在一些实施例中，步骤S504中，基于室内机的盘管温度、第一预设温度阈值、第二预设温度阈值调节空调器100的压缩机170的频率和室内机的风机120的转速的步骤包括：
实时获取室内机的换热器220的盘管温度；
判断盘管温度与第一预设温度阈值、第二预设温度阈值的大小；
当盘管温度大于等于第一预设温度阈值时，控制压缩机170以第一预设频率运行，风机120以第一预设转速运行；
当盘管温度小于第一预设温度阈值、大于第二预设温度阈值时，控制压缩机170以第二预设频率运行，风机120以第二预设转速运行，其中第二预设频率小于第一预设频率，第二预设转速小于第一预设转速；
当盘管温度小于等于第二预设温度阈值时，控制压缩机170以第三预设频率运行，风机120以第三预设转速运行，其中第三预设频率小于第二预设频率，第三预设转速小于第二预设转速。
本发明的空调器100的控制方法通过在室内机的换热器220的盘管温度小于第一预设温度阈值，对压缩机170降频，对风机120降速，在室内机的换热器220的盘管温度小于第二预设温度阈值，对压缩机170再次降频，对 风机120再次降速，可以避免盘管温度过低出现冻结保护。第一预设温度阈值可以是12℃±2℃，例如为10℃、12℃、14℃。第二预设温度阈值可以是6℃±1℃，例如为5℃、6℃、7℃。第一预设频率例如为65Hz。第一预设转速例如为900r/min。第二预设频率小于第一预设频率，可以是例如为60Hz。第二预设转速小于第一预设转速，可以是例如为860r/min。第三预设频率小于第二预设频率，可以是例如为45Hz。第三预设转速小于第二预设转速，可以是例如为760r/min。特别地，第三预设频率相对于第二预设频率的降低幅度大于第三预设转速相对于第二预设转速的降低幅度，实现较高转速较低频率的效果。以第一预设温度阈值为12℃、第二预设温度阈值为6℃、第一预设频率为65Hz、第一预设转速为900r/min、第二预设频率为60Hz、第二预设转速为860r/min、第三预设频率为45Hz、第三预设转速为760r/min为例，当检测到的室内机的换热器220的盘管温度为14℃时，控制压缩机170以65Hz运行，风机120以900r/min运行；当检测到的室内机的换热器220的盘管温度为8℃时，控制压缩机170以60Hz运行，风机120以860r/min运行；当检测到的室内机的换热器220的盘管温度为5℃时，控制压缩机170以45Hz运行，风机120以760r/min运行。对室内机的换热器220的盘管温度的检测是实时进行的，依照盘管温度对压缩机170和风机120的控制也是实时进行的。

S618：若步骤S610的判断结果为是，判断转速是否大于预设转速阈值，包括获取风机120的转速并判断转速是否大于预设转速阈值或者获取风机120所处的风速档位并判断风速档位是否是高风档；
