The invention discloses an air conditioner outdoor unit, an air conditioner and a control method of the air conditioner. The air conditioner outdoor unit comprises a heat exchanger, a fan and an air guide grid. The fan is used for reversely running when the air conditioner is in the preset mode and supplying air to the interior of the outdoor unit. The air guide grid is located between the heat exchanger and the fan and used for guiding air discharged from the fan to the heat exchanger. The problem that in the prior art, condensate water or defrosting water of the outdoor heat exchanger cannot be discharged in time is solved, and the heating capacity and reliability of the unit are improved. 本发明公开了一种空调室外机、空调及其控制方法，其中，该空调室外机包括：换热器；风机，用于在空调处于预设模式时反向运转，向室外机的内部送风；导风格栅，位于换热器和风机之间，用于将风机的出风导流至换热器。本发明解决了现有技术中室外换热器冷凝水或化霜水不能及时排出的问题，提高机组制热量和可靠性。
