However, in the rack and pinion drive scheme, the motion friction of the rack and pinion is relatively large, the energy loss is relatively large, and the working noise is relatively large.
In addition, if the rack and pinion drive scheme is a single motor movement, that is, one gear drives a rack to move, the force of opening and closing the door is unbalanced, and it is prone to deflection. If the rack and pinion drive scheme is a dual motor movement , that is, when two gears jointly drive a rack from both sides of the width, if there is inconsistency between the driving motors of the two gears, the drive of the two gears to the rack will interfere with each other, affecting the normal lifting of the door. , and it is easy to damage or shorten the life of the gear drive motor

Embodiment 1
[0056] A wire reel 31 is installed on each support 30 respectively, and two wire reels 31 are respectively connected to two ends of the rope 33 . Therefore, the structure is simple and compact.
Embodiment 2
[0058] One end of the rope 33 is fixedly connected to a support 30 , and the other support 30 is mounted with a reel 31 and connected to the other end of the rope 33 . Therefore, the cost is low, and the structure is simple and compact.
Embodiment 3
[0060] One end of the rope 33 is fixedly connected to a bearing 30, and the other bearing 30 is provided with a support pulley. Cord reel 31. Thus, the position of the cord reel 31 can be flexibly designed, for example, the cord reel 31 can be arranged on the support facing the opening and closing door 2, etc., and the cost can be reduced. In addition, in this embodiment, the cord reel 31 can be arranged on the air conditioner body 1 or the switch door 2 .

The invention discloses an air conditioner comprising an air conditioner body, an opening and closing door and a driving assembly, the opening and closing door is in sliding fit with the air conditioner body, and the opening and closing door can ascend, descend and slide between the ascending position and the descending position relative to the air conditioner body; and the driving assembly comprises supports, a winder, movable pulleys and a rope, the supports are arranged on the air conditioner body, the two supports are arranged on the two transverse sides of the opening and closing door respectively, the movable pulleys are arranged on the opening and closing door and comprise at least one first movable pulley, the first movable pulleys are located below the two supports, the rope is wound around the movable pulleys and is wound around the first movable pulleys through the bottoms of the first movable pulleys, the two ends of the rope extend and are matched with the two supports respectively, at least one end of the rope is connected with the winder, the winder winds the rope to enable the opening and closing door to ascend, and the winder unwinds the rope to enable the opening and closing door to descend. According to the air conditioner, the noise for driving the opening and closing door to move is low, and the movement of the opening and closing door is stable.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner. Background technique [0002] Some air conditioners in the related art are provided with a liftable switch door, and the air conditioner drives the lift of the switch door by setting a rack and pinion mechanism. However, in the rack and pinion drive scheme, the motion friction of the rack and pinion is relatively large, the energy loss is relatively large, and the working noise is relatively large. In addition, if the rack and pinion drive scheme is a single motor movement, that is, one gear drives a rack to move, the force of opening and closing the door is unbalanced, and it is prone to deflection. If the rack and pinion drive scheme is a dual motor movement , that is, when two gears jointly drive a rack from both sides of the width, if there is inconsistency between the driving motors of the two gears, the drive of the two gears to the rack will i...
