Description

空调器的净化控制方法和空调器 技术领域
本发明涉及智能家电控制技术领域，特别是涉及一种空调器的净化控制方法和空调器。
背景技术
目前，为了提高室内的空气质量，用户通常可以通过空调器对室内空气进行净化。但是，在对室内空气进行净化时，需要用户手动开启空调器的净化模式。手动开启空调器净化模式的方式使空调器的控制不够智能化，增加了用户的操作，降低了用户的体验。
发明内容
鉴于上述问题，提出了本发明以便提供一种克服上述问题或者至少部分地解决上述问题的空调器的净化控制方法和空调器。
本发明的一个目的是要提高空调器的智能化水平。
本发明一个进一步的目的是降低净化模式对空调器送风的风力的影响。
特别地，本发明提供了一种空调器的净化控制方法，包括：
获取空调器所在环境的空气质量指标；
判断空气质量指标是否大于第一预设阈值；
若空气质量指标大于第一预设阈值，获取空调器的风向调节模式，风向调节模式包括避免向目标人体所在区域送风的避让模式；
若风向调节模式为避让模式，启动净化模式，以对空调器送出的风进行净化。
可选地，在执行获取空调器所在环境的空气质量指标的步骤之前，还包括：
获取空调器所在环境的环境温度以及空调器的设定温度；
若设定温度和环境温度之间的差值小于预设差值，执行获取空调器所在环境的空气质量指标的步骤。
可选地，若风向调节模式不是避让模式，判断空气质量指标是否大于第二预设阈值，第二预设阈值大于第一预设阈值；
若是，启动净化模式对空调器送出的风进行净化。
可选地，若风向调节模式不是避让模式，在对空调器送出的风进行净化的过程中，继续获取空调器所在环境的空气质量指标；
当空气质量指标小于第三预设阈值时，关闭净化模式。
可选地，若空气质量指标小于第二预设阈值，获取空调器的送风强度；
若送风强度为低，启动净化模式对空调器送出的风进行净化。
可选地，若风向调节模式为避让模式，在对空调器送出的风进行净化的过程中，继续获取空调器所在环境的空气质量指标；
当空气质量指标小于第三预设阈值时，关闭净化模式。
可选地，识别目标人体所在区域的步骤包括：
通过语音定位的方式确定目标人体所在区域。
可选地，通过语音定位的方式确定目标人体所在区域的步骤包括：
采用双麦线性阵列的方式确定目标人体所在区域。
可选地，控制空调器启动避让模式的步骤包括：
获取避让模式的控制指令，根据控制指令控制空调器启动避让模式；或
获取空调器的出风口的温度；
若出风口的温度超出预设温度范围，执行避让模式。
根据本发明的另一个方面，还提供了一种空调器，包括：
存储器和处理器，存储器内存储有控制程序，控制程序被处理器执行时用于实现上述任一种空调器的净化控制方法。
在本发明的空调器的净化控制方法中，先判断空气质量指标是否大于第一预设阈值，若空气质量指标大于第一预设阈值，获取空调器的风向调节模式，若风向调节模式为避让模式，则启动净化模式对空调器送出的风进行净化。使用上述方法可以自动启动净化模式对空调器送出的风进行净化，减少了用户的操作，提高了空调器的智能化水平。另外，启动净化模式后会降低空调器的送风量。当风向调节模式为避让模式时，可以说明用户对风量的需求较小，因此，在风向调节模式为避让模式时启动净化模式，可以防止过度的减少送风量，从而避免降低用户的舒适度。
进一步地，当设定温度和环境温度之间的差值小于预设差值时，可以确认室内的温度已经达到用户需要的温度，在这样的情况下，用户可能不再需要风向朝向自己吹，即室内的温度已经满足了用户的舒适度。因此，当设定温度和环境温度之间的差值小于预设差值时，再执行获取空调器所在环境的 空气质量指标，从而可以在满足用户的舒适度的情况下对空气进行净化。

步骤S104：判断空气质量指标是否大于第一预设阈值。第一预设阈值可以定义为75～115μg/m 3之间的任意值，当然，也可以根据实际需要进行设定，本发明实施例对此不做具体地限定。
若空气质量指标大于第一预设阈值，执行步骤S106：获取空调器的风向调节模式。风向调节模式包括避免向目标人体所在区域送风的避让模式。
步骤S108：若风向调节模式为避让模式，启动净化模式，以对空调器送出的风进行净化。在本步骤中，启动净化模式可以为启动具有吸附功能的净化模块，净化模式启动后，具有吸附功能的净化模块会处于空调器的出风口的位置，从而对空调器送出的风进行净化。当净化模式关闭后，净化模块会离开空调器的出风口的位置。
在本实施例中，先判断空气质量指标是否大于第一预设阈值，若空气质量指标大于第一预设阈值，获取空调器的风向调节模式，若风向调节模式为避让模式，则启动净化模式对空调器送出的风进行净化，使用该方法可以自动启动净化模式对空调器送出的风进行净化，减少了用户的操作，提高了空调器的智能化水平。另外，启动净化模式后会降低空调器的送风量。当风向调节模式为避让模式时，可以说明用户对风量的需求较小，因此，在风向调节模式为避让模式时启动净化模式，可以防止过度的减少送风量，从而避免降低用户的舒适度。
在本发明一个实施例中，在执行步骤S102之前，还可包括：
获取空调器所在环境的环境温度以及空调器的设定温度。
若设定温度和环境温度之间的差值小于预设差值，执行步骤S102。
在本步骤中，预设差值可以为0-2摄氏度之间任意值，优选为1摄氏度。当设定温度和环境温度之间的差值小于预设差值时，可以确认室内的温度已经达到用户需要的温度，在这样的情况下，用户可能不再需要风向朝向自己吹，即室内的温度已经满足了用户的舒适度。因此，当设定温度和环境温度之间的差值小于预设差值时，再执行获取空调器所在环境的空气质量指标，从而可以在满足用户的舒适度的情况下对空气进行净化。
在本发明一个实施例中，若风向调节模式不是避让模式，则判断空气质量指标是否大于第二预设阈值，第二预设阈值大于第一预设阈值，若是，则启动净化模式对空调器送出的风进行净化。第二预设阈值可以定义为116～150μg/m 3之间的任意值，当然，也可以根据实际需要进行设定，本发明实施例对此不做具体地限定。
在本实施例中，当风向调节模式不是避让模式时，风向调节模式可以为向目标人体所在区域送风的跟随模式，也可以为上送风模式、下送风模式或者上下送风模式等。当风向调节模式不是避让模式时，也可以理解为风向调节模式为非避让模式。当空气质量指标大于第二预设阈值时，可以确认环境污染的程度较为严重，即使需要向目标人体所在区域送风，但是为了减少对人体的损害，也需要启动净化模式对空调器送出的风进行净化。
在本发明一个实施例中，若风向调节模式不是避让模式，在对空调器送出的风进行净化的过程中，继续获取空调器所在环境的空气质量指标。当空气质量指标小于第三预设阈值时，关闭净化模式。
在本实施例中，第三预设阈值可以等于第二预设阈值或第一预设阈值，当然，第三预设阈值也可以小于第二预设阈值或第一预设阈值，本发明实施例对此不做具体地限定。当空气质量指标小于第三预设阈值时，可以确认环境污染的程度较轻或者完成了对空气的净化，若风向调节模式不是避让模式，表示可能需要向目标人体所在区域送风。因此在空气质量指标小于第三预设阈值时，为了满足用户对风的需要，提高用户的舒适度，关闭净化模式。
在本发明一个实施例中，若空气质量指标小于第二预设阈值，获取空调器的送风强度。若送风强度为低，启动净化模式对空调器送出的风进行净化。
在本实施例中，在空气质量指标小于第二预设阈值且大于第一预设阈值时，若送风强度为低，可以确认用户对风的需求较小，为了减少对人体的损害，也需要启动净化模式对空调器送出的风进行净化。
在本发明一个实施例中，若风向调节模式为避让模式，在对空调器送出的风进行净化的过程中，继续获取空调器所在环境的空气质量指标。当空气质量指标小于第三预设阈值时，关闭净化模式。
在本实施例中，当空气质量指标小于第三预设阈值时，可以确定环境污染的程度较轻或者完成了对空气的净化，为了节约电能，可以关闭净化模式。
在本发明一个实施中，识别目标人体所在区域的步骤可包括通过语音定位的方式确定目标人体所在区域。具体地，例如，可采用双麦线性阵列的方式确定目标人体所在区域。
在本实施例中，如图2所示，双麦线性阵列的麦克风1和麦克风2可以在空调器朝向目标人体方向的0～180°的平面内形成N个波束，每个波束对应360/N的录音范围。N为大于1的整数，例如，N可以为3，波束分别为波束0、波束1和波束2。麦克风1和麦克风2可以设置在空调器的面板上。采用双麦的成本较低，也可以实现对整个房间范围内的目标人体所在区域的定位。当然，本发明实施例对麦的个数不做具体地限定，也可以采用六麦或其他个数。
在本发明一个实施中，控制空调器启动避让模式的步骤可包括：
获取避让模式的控制指令，根据控制指令控制空调器启动避让模式。或
获取空调器的出风口的温度，若出风口的温度超出预设温度范围，则启动避让模式。
在本实施例中，预设温度范围一般可以为人体感觉较为舒适的温度范围， 如18-25摄氏度。若出风口的温度超出预设温度范围，则执行避让模式。或者，获取避让模式的控制指令，然后根据控制指令控制空调器启动避让模式。
参见图3，图3是根据本发明另一个实施例的空调器的净化控制方法的流程图。该方法可包括如下步骤S302至步骤S326。
步骤S302：获取空调器所在环境的环境温度以及空调器的设定温度。
步骤S304：判断设定温度与环境温度之间的差值是否小于预设差值。预设差值可以为0-2摄氏度之间任意值，优选为1摄氏度。
若否，返回步骤S302。
若是，执行步骤S306：获取空调器所在环境的空气质量指标。空气质量指标可以为室内的PM2.5的指标。例如可根据24小时的PM2.5平均值确定室内的PM2.5指标。具体地，可将空气质量划分为多个等级，优：0～35μg/m 3；良：35～75μg/m 3；轻度污染：75～115μg/m 3；中度污染：115～150μg/m 3；重度污染：150～250μg/m 3；严重污染：250μg/m 3及以上。
步骤S308：判断空气质量指标是否大于第一预设阈值。第一预设阈值可以定义为75～115μg/m 3之间的任意值，当然，也可以根据实际需要进行设定，本发明实施例对此不做具体地限定。
若空气质量指标小于第一预设阈值，返回步骤S306。
若空气质量指标大于第一预设阈值，执行步骤S310：获取空调器的风向调节模式。风向调节模式包括避免向目标人体所在区域送风的避让模式，也可以包括上送风模式、下送风模式、上下送风模式和向目标人体所在区域送风的跟随模式等。
步骤S312：判断风向调节模式是否为避让模式。
若为避让模式，执行步骤S314：启动净化模式对空调器送出的风进行净化。
若否，执行步骤S316：判断空气质量指标是否大于第二预设阈值。第二预设阈值大于第一预设阈值。第二预设阈值可以定义为116～150μg/m 3之间的任意值，当然，也可以根据实际需要进行设定，本发明实施例对此不做具体地限定。
若大于第二预设阈值，执行步骤S314。
若小于第二预设阈值，执行步骤S318：获取空调器的送风强度。送风强度一般可以分为低、中、高。
步骤S320：判断送风强度是否为低。
若否，返回执行步骤S302。
若送风强度为低，执行步骤S314。
在执行步骤S314之后，还可执行步骤S322：获取空调器所在环境的空气质量指标。
步骤S324：判断空气质量指标是否小于第三预设阈值。第三预设阈值可以等于第二预设阈值或第一预设阈值，当然，第三预设阈值也可以小于第二预设阈值或第一预设阈值，本发明实施例对此不做具体地限定。
若是，执行步骤S326：关闭净化模式。
若否，返回执行步骤S322。
在本实施例中，先判断空气质量指标是否大于第一预设阈值，若空气质量指标大于第一预设阈值，获取空调器的风向调节模式，若风向调节模式为避让模式，则启动净化模式对空调器送出的风进行净化，使用该方法可以自动启动净化模式对空调器送出的风进行净化，减少了用户的操作，提高了空调器的智能化水平。并且，当风向调节模式为避让模式时，可以说明用户对风量的需求较小，因此，在风向调节模式为避让模式时启动净化模式，可以减少净化模式对送风量的影响，从而避免降低用户的舒适度。当设定温度和环境温度之间的差值小于预设差值时，可以确认室内的温度已经达到用户需要的温度，在这样的情况下，用户可能不再需要风向朝向自己吹，即室内的温度已经满足了用户的舒适度。因此，当设定温度和环境温度之间的差值小于预设差值时，再执行获取空调器所在环境的空气质量指标，从而可以在满足用户的舒适度的情况下对空气进行净化。

处理器402和存储器401用于形成空调器400的控制装置，该控制装置可以为主控板。处理器402可以是一个中央处理单元(CPU)，或者为数字处理单元(DSP)等等。存储器401用于存储处理器402执行的程序。存储器401可以是能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何介质，但不限于此。存储器401也可以是各种存储器401的组合。由于机器可执行程序被处理器402执行时实现上述方法实 施例的各个过程，且能达到相同的技术效果，为避免重复，这里不再赘述。
