It is more convenient and beneficial to prolong the service life of the driving system 120 and the dust cover. The specific structure inside the drive system is not particularly limited, and it only needs to be used as the drive system 120 to drive the dust cover pulling structure 310 and the support structure to reciprocate. In this way, the installation space can be saved, and at the same time, the air conditioner can be installed indoors. When the machine 100 is retrofitted, the retrofit cost can be minimized, the use of more molds can be avoided, and it is more convenient for large-scale use.

According to some embodiments of the present invention, the material of the dustproof portion 130 may include various materials. For example, the dustproof part 130 can be made of solid film, cloth, silk, etc., can be set by printing, and set with various colors or patterns. In addition, the dustproof part 130 can also be a hard or soft structure to adapt to different indoor environmental conditions. It should be noted that, in some cases, the dust-proof portion is opaque, and this arrangement can prevent various lights from irradiating the air conditioner and delay the aging of the air conditioner.

According to some embodiments of the present invention, the dust cover further includes a connecting piece 360 , and one end of the connecting piece 360 is connected to the fixed end of the dustproof portion 130 .
