附图说明
为了更清楚地说明本申请或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作一简单地介绍，显而易见地，下面描述中的附图是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

图2是本申请提供的空调室外机除霜方法的流程示意图之二；
图3是本申请提供的电控箱的结构示意图；
图4是本申请提供的空调室外机除霜装置的结构示意图。
具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
下面结合图1-图2描述本申请提供的空调室外机除霜方法的流程。
图1是本申请提供的空调室外机除霜方法的流程示意图之一。如图1所示，本申请提供一种空调室外机除霜方法，其包括：
步骤110：在满足除霜预设条件时进入除霜模式，
步骤120：控制空调器下出风模块中的下出风风机反向转动以向外排风。
其中，空调器下出风模块通过通风管路与空调室外机连通，通风管路的端部靠近冷凝器的一侧或者正对冷凝器。
当空调器满足除霜预设条件后，启动除霜模式，在原有除霜模式的执行过程中，控制下出风模块中的下出风风机反向运行，向外排风。通常空调室外机在空调运行制热模式时会发生结霜，原有除霜模式可以定时启动或根据时间-温度差控制启动或者根据冷凝温度启动均可，在原有除霜模式启动的同时，控制下出风风机向外排风，以向外排风时下出风风机的转向为反向。下出风风机反向运行，使室内的热空气通过通风管路排至冷凝器，加速空调室外机的化霜和化冰，缩短霜和化冰时间。同时，由于室内的热空气被下出风风机抽出去，室内气压较低，形成负压区，有助于室内空气的更新。
本申请实施例提供的空调室外机除霜方法，在执行原除霜模式的同时下出风模块向外排放室内的热空气，热空气经由通风管路排放至冷凝器处，从而缩短除霜化冰的时间，通常除霜过程，用户舒适度较差，缩短除霜化冰时间可以有效改善用户的使用体验，提升舒适度。通常除霜模式在空调器制热模式运行一段时间后启动，因制热模式容易导致室内空气污浊，现在常用的方式是通过新风模块向室内通入新风，而本申请提供的空调室外 机除霜方法，除霜的同时在室内形成负压区，以便室外空气进入室内，有助于更新室内空气。
图2是本申请提供的空调室内机除霜控制方法的流程图之二。在上述实施例基础上，如图2所示，本申请实施例提供的空调室内机除霜控制方法还包括：
步骤130：进入除霜模式时还控制空调器下出风模块中的电加热运行。也即空调器运行原有除霜模式的同时，下出风模块中的电加热和下出风风机均运行，对室内的热空气进行二次加热，进一步提升输送至冷凝器的空气温度，加速除霜化冰效率。
本申请实施例提供的空调室内机除霜控制方法，下出风模块中的电加热运行加热室内的热空气，进一步提高通风管路排出的空气温度，进一步提高除霜化冰效率，缩短除霜化冰时间。
本申请实施例提供的空调室内机除霜控制方法，具体包括：获取空调室外机的盘管温度，根据盘管温度控制下出风风机的转速和/或电加热的工作效率。在除霜过程中，通过盘管温度调节下出风风机的转速和/或电加热的工作效率，以降低能耗，高效除霜化冰。
比如，在盘管温度小于第一预设温度时，下出风风机反向高速运行；待盘管温度大于等于第一预设温度且小于第二预设温度时，下出风风机反向中速运行；待盘管温度大于等于第二预设温度时，下出风风机反向低速运行。可以理解的，第一预设温度小于第二预设温度。
又如，在盘管温度小于第一预设温度时，下出风风机反向高速运行，电加热高功率运行。待盘管温度大于等于第一预设温度且小于第二预设温度时，下出风风机反向中速运行，电加热功率下调；待盘管温度大于等于第二预设温度时，下出风风机反向低速运行，电加热停止，借助余热化霜。可以理解的，第一预设温度小于第二预设温度。
当然，也可以根据除霜模式的运行时间控制下出风风机的转速和/或电加热的工作效率。比如，可以将除霜模式的运行时间分为三个阶段，在初始阶段，控制下出风风机的转速和/或电加热的工作效率。在第二时间阶段，下调下出风风机的转速和/或下调电加热的工作效率。在第三时间阶段，进一步下调下出风风机的转速和/或电加热的工作效率。
在上述任一实施例基础上，除霜模式运行结束时，根据室内空间的下部温度与上部温度控制下出风风机和电加热的运行。空调器下出风模块与空调器主出风模块分别独立运行，若室内空间中的下部温度和上部温度之间的差值大于等于2°，则控制下出风模块中的下出风风机和电加热运行，下出风模块排出热风，补偿室内下部的空气温度。若室内空气中的下部温度和上部温度之间的差值小于2°，则下出风风机和电加热停止运行。
本申请实施例提供的空调室外机除霜方法，包括：
判断空调器是否满足除霜预设条件，在满足除霜预设条件时进入除霜模式，并控制空调器下出风模块中的下出风风机反向转动以向外排风；其中，空调器下出风模块通过通风管路与空调室外机连通，通风管路的端部靠近冷凝器的一侧或者正对冷凝器。
在此基础上，进一步控制下出风模块中的电加热运行加热室内热空气，提高通风管路排出的空气温度，有效缩短除霜化冰时间。
其中，电加热的运行效率和下出风风机的转速根据空调室外机的盘管温度控制，可以根据分为三个控制档位或者两个控制档位。
在除霜结束后，根据室内空间的上部温度和下部温度之间的差值大小控制下出风模块的工作状态。在温差大于等于2°时，下出风模块启动电加热，向室内排热风，调节室内空间的下部温度，缩小室内上部和下部之间的温差。在温差小于2°时，下出风模块的电加热关闭节能。
本申请提供的空调室外机除霜方法，利用空调下出风模块中的下出风风机反向运行向外输送热空气，在进行除霜化冰的同时还能促进室内空气的更新，对制热模式下的空气调节起到良好的调节作用，提高用户的使用体验。

其中，下出风风机为贯流扇，下出风模块的出风口通过通风管路与室外机的壳体相连，通风管路的一端管口位于冷凝器的一侧或正对冷凝器。
本申请实施例提供的空调器，包括空调室内机和空调室外机。空调室内机包括主风道及位于主风道下方的下出风模块，在制热模式下，下出风模块用于向室内下部提供热空气，以避免室内空间的上部温度和下部温度偏差过大。其中，下出风模块包括下出风风机和电加热，下出风风机为贯流扇，电加热为PTC电辅热或者电阻丝等加热元件。下出风风机可以反向运行，在除霜模式下，下出风模块中的下出风风机反向运行向外排放热空气，下出风模块通过通风管路为冷凝器提供热风，以辅助除霜化冰。空调室外机中，轴流扇设置在冷凝器的下风口，也即，空气流动时先经过低温的冷凝器然后再经过轴流扇，使空气中的热量被冷凝器充分利用，减少热 量散失。
可以理解的，该空调器中，下出风模块在制热模式下，通过下出风风机的正向运行独立进风，其既可以作为新风模块向室内输送新风，也可以启动电加热作为调节室内空间下部温度的辅助模块。
