The utility model discloses an air -conditioner, but the air -out subassembly and the pivot ground that include the host shell, set up on the host shell set up at the outside panel components of host shell, still include panel components moving part, under the state of air -conditioner work, panel components moving part drive panel components exposes the air -out subassembly, when the air -conditioner stop work, panel components moving part drive panel components is closed and be close to to the host shell, until laminating with the host shell. Above -mentioned air -conditioner has the aesthetic property of preferred when the stop work, and reducible dust gets into.
