Problems solved by technology

[0006] However, such a conventional top-mounted air conditioner has a problem that the ropes are not evenly wound around the reel when the suction grill is lifted by the operation of the lifting device, or the ropes are stretched differently from each other due to long-term use and they are different in length. In different cases presented above, the suction grille cannot be closed accurately
Although the suction grille can be closed evenly to a certain extent through the action of the coil springs installed on each reel and the control operation of the control method, there are still problems when the coil springs fail or the ropes are damaged due to long-term use. Problem with not closing evenly on all sides of the suction grille in case of overstretching
