Of course, in some embodiments, the roller assembly 400 may also be disposed on the top of the door 300 to improve the flexibility of the door 300.

In this driving process, since the entire weight of the door 300 is carried by the roller assembly 400, when the rack 520 drives the door 300, the rack 520 receives only a small resistance (only against the static friction of the roller) of the door 300, i.e., the load of the driving gear 510 and the rack 520 is small. Thereby being beneficial to prolonging the service lives of the driving gear 510 and the rack 520, improving the stability of the driving assembly 500 and improving the stability of the movement of the door 300.

When the door 300 moves along with the roller assembly 400 to open or close the air outlet 110, the whole weight of the door 300 is transferred to the roller assembly 400 through the bottom of the door 300 and then transferred to the shell 100 by the roller assembly 400, so that the roller assembly 400 supports the door 300 from the bottom of the door 300, the upper part and the middle part of the whole door 300 are not acted by acting force, the door 300 is not acted by deformation force in the moving process, the door 300 can keep the shape of the door 300, the occurrence of deformation of the door 300 in the using process is avoided, the service life of the door 300 is prolonged, and the stability of the door 300 in operation is improved.

In order to facilitate the assembly and disassembly of the door 300, a support column 521 is arranged on the side of the rack 520 facing away from the teeth; the cabinet air conditioner further comprises a connecting piece 600, wherein the connecting piece 600 is connected with the door body 300 and the roller assembly 400; the connecting piece 600 is provided with a hanging lug 610 corresponding to the supporting column 521, the hanging lug 610 is provided with a slot 611, and the supporting column 521 is inserted into the hanging lug 610.

In this embodiment, the connector 600 may be in various forms, for example, a connection plate is used as an example, and the length direction of the connector 600 is along the width direction of the door 300. A mounting bracket 620 is provided at one side of the connector 600 in the width direction, i.e., the length direction of the door 300, and a hanger 610 connected to the housing 100 is provided at the other side. The connection plate is exemplified by an arc plate, and the connection plate is connected to the door body 300 by a fastener such as a screw.

The mounting frame 620 is provided with a mounting hole along the width direction of the connector 600, and the bracket 410 is provided with a fixing hole corresponding to the mounting hole and further comprises a rotating shaft for mounting the work roller. The extending direction of the rotating shaft is perpendicular to the plate surface of the door body 300 and is also perpendicular to the plate surface of the connecting plate. The roller takes a rolling bearing as an example, an inner ring of the roller is sleeved on the rotating shaft, and an outer wheel rotates under the action of external force.

The support column 521 and the rack 520 are integrally formed, so that noise generated due to friction between the support column 521 and the rack 520 is avoided when the door body 300 is driven, and stability is improved.

The lugs 610 may take many forms, for example having slots 611 that fit into the support posts 521. When the door 300 is mounted to the driving assembly 500, the slot 611 of the connector 600 is only required to correspond to the support column 521, and then the door 300 (the connector 600) is pressed down. The door 300 is very convenient and quick to install, disassemble and maintain by the arrangement of the hanging lugs 610 and the supporting columns 521.

In order to improve the convenience of installing the roller assembly 400 and the connector 600, a positioning buckle 411 is disposed at one end of the bracket 410, and a buckle position 621 is disposed on the mounting frame 620 corresponding to the positioning buckle 411. In this embodiment, the positioning buckle 411 includes a connecting arm and a buckling portion, the connecting arm extends from the bracket 410 to the connector 600, and the buckling portion cooperates with a buckling portion 621 provided on the mounting frame 620. When the roller assembly 400 is mounted on the mounting frame 620, the roller is sleeved on the rotating shaft, the positioning buckle 411 is inserted into the buckling position 621, the pre-mounting of the roller assembly 400 is realized, and after the pre-mounting, the roller assembly 400 is mounted on the mounting frame 620 through the mounting hole and the fixing hole by using screws. By the arrangement of the positioning buckle 411, the roller assembly 400 is more convenient to install.

Referring to fig. 8 and 9, in order to further reduce the load of the driven rack 520 while providing a buffer for door overload, a gap is provided between the top of the support column 521 and the bottom of the slot 611; and/or, a gap is formed between the bottom of the hanging lug 610 and the bottom of the supporting column 521.

In this embodiment, the slot 611 is inversely fastened to the support column 521, and a gap is formed between the top of the support column 521 and the top of the slot 611, or a gap is formed between the bottom of the hanging tab 610 of the slot 611 and the bottom of the support column 521 (where the support column 521 is connected to the driven rack 520). Of course, in some embodiments, both of the above positions may have a gap. By reserving a gap between the top of the support column 521 and the top of the slot 611, the top of the support column 521 is not abutted by the hanger 610; by reserving a gap between the notch of the slot 611, i.e., the bottom of the hanger 610 and the bottom of the support column 521 (where the support column 521 is connected to the driven rack 520), there is no abutment between the hanger 610 and the driven rack 520. By reserving gaps at the two positions, the support column 521 is free from the action of the door body in the vertical direction, so that the flexibility of the movement of the support column 521 is ensured, and meanwhile, the weight of the door body is prevented from being transmitted to the driven rack 520 through the support column 521, so that the driven rack 520 is prevented from being subjected to the load in the vertical direction. When the door body is overloaded and moves downwards, the two gaps can provide buffer space for the falling of the door body, and the support columns 521 can provide buffer support for the door body.

In order to reduce the influence of external environmental factors on the operation of the driving assembly 500 and improve the stability of the operation of the driving assembly 500, the driving assembly 500 further includes a gear box detachably connected to the housing 100; the gear box comprises a base 530 and a box cover 540 detachably connected with the base 530; the base 530 is provided with a guide groove 531 for the rack 520 to slide, and the rack 520 is provided with a guide piece 522 corresponding to the guide groove 531; the guide 522 extends from the base 524 of the rack 520 along the length of the drive teeth.
