A method for controlling an air conditioner, wherein the air conditioner comprises: a housing, wherein the housing comprises: an air outlet passage formed in the housing; and an air outlet arranged in an outer peripheral wall of the housing and communicated with the air outlet passage; a first air guiding plate rotatably arranged at the air outlet and connected with the housing by a first rotating shaft on the housing; and a second air guiding plate arranged in the air outlet passage, and being capable of rotating around a second rotating shaft in the housing, wherein the first air guiding plate is arranged to rotate around the first rotating shaft to open or close the air outlet and the second air guiding plate is provided with a plurality of second air dispersing holes passing through the second air guiding plate, wherein the second air dispersing holes are arranged along the thickness direction of the second air guiding plate, wherein the air conditioner comprises a breeze mode, in response to the air conditioner operating in the breeze mode, a part of the air outlet is shielded by the first air guiding plate, and the second air guiding plate is rotated to a lower side of the air outlet in the air outlet passage characterized in that in response to the air conditioner operating in the breeze mode, a far end of the first air guiding plate in the air out-blowing direction of the air outlet, a far end of the second air guiding plate in the air out-blowing direction of the air outlet, and the first rotating shaft are located substantially on a same plane, such that the blowing air is blocked by the first air guiding plate and diffused to the surroundings through the second air dispersing holes in the second air guiding plate, thereby reducing the air volume and speed of the air outlet. a housing, wherein the housing comprises: an air outlet passage formed in the housing; and an air outlet arranged in an outer peripheral wall of the housing and communicated with the air outlet passage; a first air guiding plate rotatably arranged at the air outlet and connected with the housing by a first rotating shaft on the housing; and a second air guiding plate arranged in the air outlet passage, and being capable of rotating around a second rotating shaft in the housing, an air outlet passage formed in the housing; and an air outlet arranged in an outer peripheral wall of the housing and communicated with the air outlet passage; a first air guiding plate rotatably arranged at the air outlet and connected with the housing by a first rotating shaft on the housing; and a second air guiding plate arranged in the air outlet passage, and being capable of rotating around a second rotating shaft in the housing, wherein the first air guiding plate is arranged to rotate around the first rotating shaft to open or close the air outlet and the second air guiding plate is provided with a plurality of second air dispersing holes passing through the second air guiding plate, wherein the second air dispersing holes are arranged along the thickness direction of the second air guiding plate, wherein the air conditioner comprises a breeze mode, in response to the air conditioner operating in the breeze mode, a part of the air outlet is shielded by the first air guiding plate, and the second air guiding plate is rotated to a lower side of the air outlet in the air outlet passage characterized in that in response to the air conditioner operating in the breeze mode, a far end of the first air guiding plate in the air out-blowing direction of the air outlet, a far end of the second air guiding plate in the air out-blowing direction of the air outlet, and the first rotating shaft are located substantially on a same plane, such that the blowing air is blocked by the first air guiding plate and diffused to the surroundings through the second air dispersing holes in the second air guiding plate, thereby reducing the air volume and speed of the air outlet.
