AI Technical Summary
Technical Problem
Existing air conditioners have loud drain pump noise after shutdown, incomplete drainage, and are prone to water accumulation in the drip tray, which can breed bacteria and affect user experience.
Method used
By adjusting the height and speed of the drain pump to maintain a constant draft, the noise of the drain pump can be reduced, and the backflow can be slowly reduced when the pump stops to minimize backflow noise.
Benefits of technology
It effectively drains condensate from the drip tray, reduces water accumulation, lowers drainage and return noise, and improves the user experience.

Abstract
本发明公开了一种空调器,包括:接水盘;排水泵,其用于将所述接水盘中的冷凝水排出至外部;水泵驱动单元,其用于驱动排水泵运转;升降驱动单元,其用于驱动排水泵升降;主控单元被配置在接收到空调器的关机信号后,排水泵保持关机前的转速,并控制升降驱动单元降低排水泵,直至排水泵降低至降低高度;在排水泵降低至所述降低高度时,主控单元向水泵驱动单元发送降速指令,直至排水泵的反馈电流达到预设电流,之后,主控单元控制排水泵停止,并控制排水泵上升至初始高度。本发明能够解决接水盘中残留过多积水、排水噪音及回水噪音的问题。
