Door sheet driving box of air-conditioner and air-conditioner

The utility model discloses a door sheet driving box of an air-conditioner and the air-conditioner. The door sheet driving box of the air-conditioner comprises a moving component box and a moving component rack; the moving component rack is arranged in the moving component box and can be driven by a gear to move relatively to the moving component box; the door sheet driving box further comprises a limiting assembly which comprises a shaft and a bearing arranged on the shaft; a limiting groove is formed in the moving component rack; the shaft passes through the limiting groove, and the two ends of the shaft are fixedly connected with the upper surface and the bottom surface of the moving component box, respectively; the bearing is closely fitted with the sidewall of the limiting groove, and capable of rolling relatively to the sidewall of the limiting groove. The moving component rack in the moving component box can be effectively prevented from outward pulling and moving in the longitudinal direction under the action of the gravity of the large door sheet of the cylindrical air conditioner. As a result, the design clearance of the driving box can be still remained even in the state of deformation of an internal part in the moving component box, normal operation of a moving component inside the driving box is guaranteed and the component can be prevented from damage.
