背景技术
压缩机排气温度过高时，不仅会使制冷剂和润滑油在与金属等物质接触下分解，生成积碳和酸类等，也会使润滑油的粘度降低，导致压缩机内产生不应有的磨损，甚至引起压缩机的内置电机烧毁。总之，排气温度过高会影响压缩机的寿命。目前，在实际应用中，例如具备压缩机的干衣机中，通过增加压缩机散热风扇来降低压缩机的排气温度。然而这种方案需要在干衣机中新增额外的散热风扇，成本较高，导致干衣机的价格也增高，不利于推广。

为使本公开的目的、技术方案和优点更加清楚，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开的一部分实施例，而不是全部的实施例。基于 本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
需要说明的是，本公开的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本公开的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
下面，将结合附图并参考实施例，对本说明书实施例提供的压缩机排气温度的控制方法进行详细描述。
请参见图1，是本公开实施例提供的一种压缩机排气温度的控制方法的流程示意图。如图1所示的方法可以应用于配置有压缩机和引风阀门的家电设备中，所述家电设备可以为应用于调节压缩机排气温度的家电设备，例如所述家电设备包括但不限于干衣机、空调器、空调扇、新风设备、电暖器或其他设备。所述方法包括如下实施步骤。
S101、在检测到压缩机处于目标运行阶段时，获取所述压缩机的排气参数，所述排气参数至少包括所述压缩机的排气温度。
本公开所述目标运行阶段是指压缩机当前所处的运行阶段，其划分标准不作限定，例如根据压缩机排气温度的变化趋势可划分为升温阶段和降温阶段。所述排气参数是指用于描述所述压缩机排气的相关参数，其可包括但不限于排气温度、排气压力、排气时间、排气量或其他排气参数等。
在实际应用中，在家电设备(例如干衣机或空调)中，在家电设备运行过程中，本公开可实时或周期性地监测家电设备中的压缩机是否进入目标运行阶段，进而实施本公开提供的压缩机排气温度的控制方案，以保护压缩机不被过温停机或损毁。
可理解的，为节省设备能耗，本公开所述目标运行阶段可指压缩机运行一定时长后所处的运行阶段。例如可为所述压缩机运行第一预设时长后的升温阶段，也可为所述压缩机运行第二预设时长后的降温阶段等，以避免采集第一预设时长前压缩机的排气参数，此时压缩机刚启动运行，压缩机排气 温度处于安全的预设标准范围内，例如仍在0～105℃等等。
S102、根据所述排气温度，调节所述目标运行阶段中引风阀门的开度，以调节所述压缩机的排气温度。
在一实施方式中，本公开可直接根据排气温度来调节目标运行阶段中引风阀门的开度，例如当排气温度大于预设的上限温度阈值时，可关闭引风阀门。当排气温度小于预设的下限温度阈值时，可打开引风阀门等。
在另一实施方式中，在步骤S102之前，本公开可先获取所述排气参数随时间变化的变化趋势信息。
本公开所述变化趋势信息用于表征所述排气参数随时间变化的变化信息，其可包括但不限于变化趋势，例如上升趋势、下降趋势或平稳趋势；变化速率，例如升温速率(也可称为上升速率)、降温速率(也可称为下降速率)等。
然后在步骤S102中，本公开可根据所述排气温度及所述变化趋势信息，调节所述目标运行阶段中引风阀门的开度，以调节所述压缩机的排气温度。
本公开涉及的所述引风阀门是指家电设备中配置的阀门，其用于向家电设备中引入空气，用以降低压缩机的排气温度，进而保障压缩机不停机或不被损坏。
在一实施方式中，所述目标运行阶段为升温阶段，所述变化趋势信息用于指示所述排气温度随时间变化的变化趋势。在所述变化趋势信息用于指示所述排气温度随时间变化呈上升趋势，且所述排气温度超过第一阈值时，本公开可增大所述引风阀门的开度至预设阀门开度(例如预设的开度1等)。在一些实施方式中，所述压缩机的排气温度可继续升温，本公开可持续获取所述压缩机的排气温度，在排气温度升温超过第二阈值时，本公开可继续增大所述引风阀门的开度直至阀门的预设上限开度，例如按照预设步长或预设档次继续增大阀门开度等，以减小所述压缩机的排气温度。其中，所述第二阈值大于所述第一阈值。
在实际应用中，所述第一阈值和所述第二阈值可指单个预设的温度阈值，也可指预设温度阈值范围中的任一温度阈值等，本公开不做限定。例如所述第一阈值可为60℃-105℃中的任一预设数值，所述第二阈值可为70℃-110℃中的任一预设数值等。
在又一实施方式中，所述目标运行阶段为降温阶段，所述变化趋势信息用于指示所述排气温度随时间变化的变化趋势。在所述变化趋势信息用于指示所述排气温度随时间变化呈下降趋势，且所述排气温度超过第一阈值时，本公开可减小所述引风阀门的开度，以维持所述压缩机的排气温度处于预设标准范围内，例如处于预设的安全运行范围60℃-105℃等。
在又一实施方式中，所述目标运行阶段为升温阶段，所述变化趋势信息用于指示所述排气温度随时间变化的变化速率。在所述排气温度超过第一阈值时，本公开可增大所述引风阀门的开度至预设阀门开度(例如预设的开度1等)。在一些实施方式中，本公开可持续获取所述压缩机的排气参数，并分析获得所述排气参数随时间变化的变化趋势信息，所述变化趋势信息用于指示所述排气温度随时间变化的升温速率。在所述升温速率超过第一速度，且所述排气温度超过第一阈值时，本公开可继续增大所述引风阀门的开度直至预设上限开度，例如按照预设步长持续增大阀门开度或按照预设档次增大阀门开度等，以减小所述压缩机的排气温度。
在又一实施方式中，所述目标运行阶段为降温阶段，所述变化趋势信息用于指示所述排气温度随时间变化的变化速率，本公开实施例可用于指示所述排气温度随时间变化的降温速率。在所述变化趋势信息所指示的降温速率超过第二速率，且所述排气温度低于第一阈值时，本公开可减小所述引风阀门的开度，例如按照预设减小步长持续减小阀门开度、或按照预设档次减小阀门开度等，以维持所述压缩机的排气温度处于预设标准范围内。
在又一实施方式中，所述目标运行阶段为升温阶段，所述变化趋势信息用于指示所述排气压力随时间变化的变化趋势。在所述排气温度超过第一阈值时，本公开可增大所述引风阀门的开度至预设阀门开度(例如预设的开度1等)。在一些实施方式中本公开可获取所述变化趋势信息，在所述变化趋势信息用于指示所述排气压力随时间变化呈上升趋势，且所述排气温度超过第一阈值时，本公开可继续增大所述引风阀门的开度直至预设上限开度，例如按照预设步长持续增大阀门开度或按照预设档次增大阀门开度等，以减小所述压缩机的排气温度。
在又一实施方式中，所述目标运行阶段为降温阶段，所述变化趋势信息用于指示所述排气压力随时间变化的变化趋势。在所述变化趋势信息用于指示所述排气压力随时间变化呈下降趋势或平稳趋势，且所述排气温度超过第一阈值时，本公开可减小所述引风阀门的开度，例如按照预设减小步长持 续减小阀门开度、或按照预设档次减小阀门开度等，以维持所述压缩机的排气温度处于预设标准范围内。
需要说明的是，除上述各实施方式外，本公开实施例还可根据其他排气参数及其的变化趋势信息来调节引风阀门的开度，从而达到调节压缩机排气温度的目的。例如参考前述排气温度的变化速率及排气温度调节阀门开度的实施例，本公开可对应根据排气压力的变化速率(例如升压速率或降压速率)及排气温度来调节阀门开度。或者，又如本公开可根据排气温度和当前排气时间来调节引风阀门的开度，在排气温度超过第一阈值，且当前排气时间超过第一预设时间(反映压缩机长时间运行排气等)时，可逐渐增大引风阀门的开度，来降低压缩机的排气温度等，本公开不做限定。

    若所述变化趋势信息所指示的升温速率超过第一速率，且所述排气温度超过第一阈值，则增大所述引风阀门的开度直至预设上限开度，以减小所述压缩机的排气温度。
  6. 根据权利要求2所述的方法，其中，所述目标运行阶段为降温阶段，所述变化趋势信息指示所述排气温度随时间变化的降温速率，所述根据所述排气温度及所述变化趋势信息，调节所述目标运行阶段中引风阀门的开度包括：
    若所述变化趋势信息所指示的降温速率超过第二速率，且所述排气温度低于第一阈值，则减小所述引风阀门的开度，以维持所述压缩机的排气温度在预设标准范围内。
  7. 根据权利要求2所述的方法，其中，所述排气参数还包括排气压力，所述目标运行阶段为升温阶段，所述根据所述排气温度及所述变化趋势信息，调节所述目标运行阶段中引风阀门的开度包括：
    若所述变化趋势信息指示所述排气压力随时间变化呈上升趋势，且所述排气温度超过第一阈值，则增大所述引风阀门的开度直至预设上限开度，以减小所述压缩机的排气温度。
  8. 根据权利要求2所述的方法，其中，所述排气参数还包括排气压力，所述目标运行阶段为降温阶段，所述根据所述排气温度及所述变化趋势信息，调节所述目标运行阶段中引风阀门的开度包括：
    若所述变化趋势信息指示所述排气压力随时间变化呈下降趋势或平稳趋势，且所述排气温度超过第一阈值，则减小所述引风阀门的开度，以维持所述压缩机的排气温度在预设标准范围内。
  9. 根据权利要求1-8中任一项所述的方法，其中，所述目标运行阶段为所述压缩机运行第一预设时长后的升温阶段，或者所述目标运行阶段为所述压缩机运行第二预设时长后的降温阶段。
  10. 一种压缩机排气温度的控制装置，包括：
    获取模块，用于在检测到压缩机处于目标运行阶段时，获取所述压缩机的排气参数，所述排气参数至少包括所述压缩机的排气温度；
    调节模块，用于根据所述排气温，调节所述目标运行阶段中引风阀门的开度。
  11. 一种家电设备，包括压缩机、引风阀门及处理器，所述处理器用于调用存储器中存储的程序实现权利要求1-9中任一权利要求所述方法。
  12. 一种计算机可读存储介质，其上存储有计算机程序，该程序被处理器执行时实现权利要求1-9任一项所述方法的步骤。
