本申请提供一种空调器的控制方法。
参照图2，图2为本申请空调器的控制方法第一实施例的流程示意图。
本实施例提出一种空调器的控制方法，该空调器的控制方法包括：
S10，获取空调器的压缩机的第一运行频率；
S20，所述第一运行频率大于或等于预设频率，获取所述空调器的蒸发器的当前温度；
S30，所述当前温度小于预设温度，控制所述压缩机按照第二运行频率运行，其中，所述第二运行频率大于所述第一运行频率。
在空调器开机时，通过频率获取装置获取空调器的压缩机的第一运行频率。其中，可以定时获取压缩机的第一运行频率，比如，每10s获取一次压缩机的第一运行频率；或者，可以在预定时间段内获取多个压缩机的运行频率，并通过多个运行频率计算得到平均值，以多个运行频率的平均值作为该压缩机的第一运行频率。
进一步地，在获取到压缩机的第一运行频率后，判断该第一运行频率是否大于或等于预设频率，在第一运行频率大于或等于预设频率时，获取空调器的蒸发器的当前温度。其中，当前温度为蒸发器的中部温度，而蒸发器的中部温度则反应了压缩机工作的高压压力状况。
进一步地，预设频率为25Hz。当然，在其他实施例中，预设频率可以认为设定或者根据空调器的性能设置，在此并无限制。
进一步地，在当前温度小于预设温度时，控制空调器执行回油动作。其中，上述预设温度可以为预设温度值，比如，预设温度为3℃；或者，预设温度可以为预设温度区间，比如，预设温度区间为2℃～4℃。
进一步地，上述回油动作为控制压缩机按照第二运行频率运行，其中，第二运行频率大于第一运行频率。具体地，获取压缩机的第二运行频率，其中，第二运行频率为压缩机的回油频率；控制压缩机按照第二运行频率运行。即控制压缩机的第一运行频率逐渐增加至第二运行频率，并保持在第二运行频率，直到回油结束。或者，控制压缩机按照预定的调整值从第一运行频率增加至第二运行频率，该预设的调整值可为比例值，则在第一运行频率的基础上增加预设比例，以使压缩机的运行频率达到第二运行频率，例如在预设的调整值为10％时，可对第一运行频率增加10％以达到第二运行频率；或者，该预设的调整值可为一数值，对第一运行频率加上该调整值得到调整后的第二运行频率。
进一步地，第二运行频率为范围在55Hz～59Hz中的任一频率值，本实施例中，第二运行频率设置为57Hz。当然，在其他实施例中，第二运行频率并无限定。
进一步地，由于压缩机的第一运行频率大于或等于预设频率，即第一运行频率大于25Hz，此时，通过判断蒸发器的中部温度，从而能够确定空调器是否以较低频率运行，即本实施例的当前温度是否小于预设温度值，或者，是否处于预 设温度区间内，可以确定空调器仍然以较低频率运行，即此时，控制空调器执行回油动作压缩机按照第二运行频率运行，即控制压缩机按照第二运行频率运行。
具体地，获取当前温度小于预设温度的第一持续时长，即获取蒸发器的中部温度持续小于预设温度的时长，判断第一持续时长大于或等于第一预定时长，在第一持续时长大于或等于第一预定时长时，控制压缩机按照第二运行频率运行。其中，第一预定时长为30min，即在第一持续时长大于或等于30min时，能够确认空调器仍然以较低频率运行，此时，即可控制压缩机按照第二运行频率运行。
由于第一持续时长为持续的时间，即当前温度持续小于预设温度的时间，即当在某个时间点，当前温度大于或等于预设温度时，即以该时间点作为第一持续时长，比如，从当前温度小于预设温度的第一分钟开始计算，在第二十分钟时，当前温度出现大于预设温度的情况，即第一持续时长为二十分钟，此时，第一持续时长小于第一预定时长，清零第一持续时长，即将第一持续时长归零，重新累计当前温度小于预设温度的第一持续时长。
进一步地，若压缩机的第一运行频率大于或等于预设频率，且第一持续时长小于第一预定时长时，则空调器的压缩机在第一预定时长内的某一个时间点以较高频率运行，此时，空调器执行正常的回油动作，即控制压缩机按照第二运行频率运行。
进一步地，当前温度大于或等于预设温度时，则压缩机按照额定频率运行，即压缩机仍以较高频率运行，此时，空调器执行正常的回油动作，即可将压缩机的运行频率从额定频率降低至第二运行频率，并保持在第二运行频率运行，直到压缩机回油结束。
进一步地，由于压缩机运行时，需要润滑油进行润滑，以减少压缩机过程中磨损，其中，润滑油存储于压缩机的机腔内，即在控制压缩机按照第二运行频率运行的过程中，获取压缩机内润滑油的当前含量，根据当前含量确定压缩机的回油时长，当确定好回油时长后，控制压缩机按照第二运行频率运行该回油时长。
具体地，上述回油时长为范围在70s～110s中的任一时长值。即当前含量较多时，回油时长可以设置为70s，即控制压缩机按照第二运行频率运行70s；当前含量较少时，回油时长可以设置为110s，控制压缩机按照第二运行频率运行110s。本实施例中回油时长设置为90s，以使压缩机的回油充足，避免压缩机的运行磨损。当然，在其他实施例中，回油时长还可以根据具体需求进行设定，在此并无限定。
进一步地，当空调器执行完回油动作后，即控制压缩机按照第二运行频率运行的时长达到回油时长，此时，压缩机内的润滑油充足，即可保证压缩机运行时不会出现干磨，避免压缩机出现磨损的情况。
进一步地，在执行完回油动作后，即控制压缩机按照第二运行频率运行的时长达到回油时长，控制压缩机的运行频率恢复至第一运行频率，以保证空调器的正常运行。
在本发明申请的实施例中，上述空调器的控制方法包括如下步骤：获取空调器的压缩机的第一运行频率；所述第一运行频率大于或等于预设频率，获取所述空调器的蒸发器的当前温度；所述当前温度小于预设温度，控制所述压缩机按照第二运行频率运行，其中，所述第二运行频率大于所述第一运行频率。即在压缩机的第一运行频率大于或等于预设频率，并在蒸发器的当前温度小于预设温度时，可以确定空调器仍然以较低频率运行，此时控制所述压缩机按照第二运行频率运行，以使空调器回油，从而增加空调器的压缩机上润滑油的油量，避免压缩机运行时的磨损。
进一步地，参照图3，基于第一实施例提出本发明申请第二实施例，在本实施例中，所述获取空调器的压缩机的第一运行频率的步骤之后，所述空调器的控制方法还包括：
S40，所述第一运行频率小于所述预设频率，获取所述第一运行频率小于预设频率的第二持续时长；
S50，所述第二持续时长大于或等于第二设定时长，执行控制所述压缩机按照第二运行频率运行的步骤。
在空调器开机时，通过频率获取装置获取空调器的压缩机的第一运行频率。其 中，可以定时获取压缩机的第一运行频率，比如，每10s获取一次压缩机的第一运行频率；或者，可以在预定时间段内获取多个压缩机的预定频率，并通过多个运行频率计算得到平均值，以多个运行频率的平均值作为该压缩机的第一运行频率。
进一步地，在获取到压缩机的第一运行频率后，判断该第一运行频率是否小于预设频率，在第一运行频率小于预设频率时，获取所述第一运行频率小于预设频率的第二持续时长。其中，预设频率为25Hz。当然，在其他实施例中，预设频率可以认为设定或者根据空调器的性能设置，在此并无限制。
进一步地，判断第二持续时长大于或等于第二预定时长，在第二持续时长大于或等于第二预定时长时，执行所述控制所述压缩机按照第二运行频率运行的步骤。其中，第二预定时长为30min，即在第二持续时长大于或等于30min时，能够确认空调器在30min内均以较低频率运行，此时，即可控制压缩机按照第二运行频率运行。
由于第二持续时长为持续的时间，即所述第一运行频率持续小于预设频率的时间，即当在某个时间点，所述第一运行频率小于预设频率时，即以该时间点作为第二持续时长，比如，从所述第一运行频率小于预设频率的第一分钟开始计算，在第十分钟时，所述第一运行频率出现大于或等于预设频率的情况，即第二持续时长为十分钟，此时，第二持续时长小于第二预定时长，清零第二持续时长，即将第二持续时长归零，重新累计当前温度小于预设温度的第二持续时长。
进一步地，若压缩机的第一运行频率大于或等于预设频率时，则空调器的压缩机在第二预定时长内的某个时间点以较高频率运行，此时，空调器执行正常的回油动作。
进一步地，上述回油动作为控制压缩机按照第二运行频率运行，其中，第二运行频率大于第一运行频率。具体地，根据回油动作获取压缩机的第二运行频率，其中，第二运行频率为压缩机的回油频率；控制压缩机按照第二运行频率运行。即控制压缩机的第一运行频率逐渐增加至第二运行频率，并保持在第二运行频率，直到回油结束。或者，控制压缩机按照预定的调整值从第一运行频率 增加至第二运行频率，该预设的调整值可为比例值，则在第一运行频率的基础上增加预设比例，以使压缩机的运行频率达到第二运行频率，例如在预设的调整值为10％时，可对第一运行频率增加10％以达到第二运行频率；或者，该预设的调整值可为一数值，对第一运行频率加上该调整值得到调整后的第二运行频率。
进一步地，第二运行频率为范围在55Hz～59Hz中的任一频率值，本实施例中，第二运行频率设置为57Hz。当然，在其他实施例中，第二运行频率并无限定。
进一步地，由于压缩机运行时，需要润滑油进行润滑，以减少压缩机过程中磨损，其中，润滑油存储于压缩机的机腔内，即在控制压缩机按照第二运行频率运行的过程中，获取压缩机内润滑油的当前含量，根据当前含量确定压缩机的回油时长，当确定好回油时长后，控制压缩机按照第二运行频率运行该回油时长。
具体地，上述回油时长为范围在70s～110s中的任一时长值。即当前含量较多时，回油时长可以设置为70s，即控制压缩机按照第二运行频率运行70s；当前含量较少时，回油时长可以设置为110s，控制压缩机按照第二运行频率运行110s。本实施例中回油时长设置为90s，以使压缩机的回油充足，避免压缩机的运行磨损。当然，在其他实施例中，回油时长还可以根据具体需求进行设定，在此并无限定。
在本申请的实施例中，上述空调器的控制方法包括如下步骤：所述第一运行频率小于所述预设频率，获取所述第一运行频率小于预设频率的第二持续时长；所述第二持续时长大于或等于第二设定时长，执行所述控制所述压缩机按照第二运行频率运行的步骤。即在压缩机的第一运行频率小于预设频率，并在第二持续时长大于或等于第二设定时长时，可以确定空调器以较低频率运行，此时控制所述压缩机按照第二运行频率运行，以使空调器回油，从而增加空调器的压缩机上润滑油的油量，避免压缩机运行时的磨损。
本申请还提出一种空调器，所述空调器包括：存储器、处理器及存储在所述存储器上并可在所述处理器上运行的空调器的控制程序，所述空调器的控制程序被所述处理器执行时实现如以上实施例所述的空调器的控制方法的步骤。

上述本申请实施例序号仅仅为了描述，不代表实施例的优劣。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本申请的技术方案本质上或者说对示例性技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，云端服务器，空调器，或者网络设备等)执行本申请各个实施例的方法。
