By providing the protrusion 272 on the guide body 271 and contacting the protrusion 272 with the groove wall of the guide groove 280, the contact area between the groove wall of the guide groove 280 and the guide 270 can be reduced, the frictional resistance of the rack 210 with respect to the movement of the drive cassette 230 can be reduced, the rack 210 can be ensured to move smoothly, and the rotation of the air guide plate 112 can be driven smoothly and reliably.

Protrusions 272 are provided on both sides of the guide body 271 in the width direction of the first container 240; thus, the opposite and spaced groove walls of the guide groove 280 are in contact with the protrusions 272 of the guide body 271, so that the contact area between the guide groove 280 and the guide 270 is sufficiently reduced, the frictional resistance is reduced, and the rack 210 is smoothly moved.

The number of the protrusions 272 provided at each side of the guide body 271 in the width direction of the first container 240 may be one, two, three, etc., and is not particularly limited herein. In a preferred embodiment, two or more protrusions 272 are provided at intervals on each side of the guide body 271 in the width direction of the first container 240, so that the protrusions 272 are reliably brought into contact with the groove walls of the guide groove 280 when the rack 210 moves relative to the driving case 230, thereby effectively reducing the frictional resistance received by the rack 210.

The protrusion 272 has a smooth convex surface, and the groove wall of the guide groove 280 contacts with the convex surface to sufficiently reduce frictional resistance to ensure smooth movement of the rack 210.

The manner of disposing the protrusion 272 on the guide body 271 can be selected as required, and the protrusion 272 and the guide body 271 of the present embodiment are integrally formed. In other embodiments, the protrusion 272 and the guide body 271 may be connected by other methods such as bonding, welding, etc., and are not limited in detail.

Referring to fig. 8 and 9, in the present embodiment, the guide 270 includes a first guide section 273 and a second guide section 274, the first guide section 273 and the second guide section 274 are sequentially connected along the direction in which the rack 210 extends relative to the driving box 230, and at least a portion of the second guide section 274 protrudes relative to the first guide section 273 along the direction of the rotation axis of the air deflector 112; one end of the rack 210 is in transmission connection with the air deflector 112, and the other end of the rack 210 is provided with a limiting piece 281, specifically, the limiting piece 281 is arranged at one end of the guide slot 280 far away from the connection position of the rack 210 and the air deflector 112; the stopper 281 may abut on a portion of the second guide segment 274 protruding from the first guide segment 273.

By abutting the limit stop 281 arranged at the end of the rack 210 not connected with the air deflector 112 with the portion of the second guide section 274 protruding from the first guide section 273, the rack 210 protruding from the driving box 230 is not easily separated from the driving box 230 when the rack 210 protrudes from the driving box 230, so as to ensure the stability of the rack 210 and ensure that the rack 210 can reliably drive the air deflector 112 to rotate.

It should be understood that when the rack 210 is extended relative to the driving box 230 and the stop piece 281 abuts against the portion of the second guiding segment 274 protruding from the first guiding segment 273, the rack 210 is extended to an extreme position relative to the driving box 230, and when the stop piece 281 abuts against the portion of the second guiding segment 274 protruding from the first guiding segment 273, the rack 210 cannot be extended relative to the driving box 230, and the size of the wind deflector 112 is maximized.

It should be noted that the limiting member 281 may be a limiting plate, a limiting block, a limiting column, or the like fixedly connected to the rack 210, and is not limited in detail herein.

In the present embodiment, all of the second guiding segments 274 protrude with respect to the first guiding segments 273 in the direction of the rotation axis of the air deflector 112; of course, in other embodiments, only the second guide section 274 at the portion connected to the first guide section 273 may protrude with respect to the first guide section 273. The rack 210 is not easily separated from the driving box 230 by ensuring that the second guiding segment 274 at the connection between the second guiding segment 274 and the first guiding segment 273 can protrude from the first guiding segment 273 and abut against the limiting member 281.

Optionally, referring to fig. 10 and 11, a side of the second container 250 facing the first container 240 is provided with a first protruding tooth 252, a side of the rack 210 facing away from the guide slot 280 is provided with a second protruding tooth 212, the first protruding tooth 252 contacts with the side of the rack 210 facing away from the guide slot 280, and the second protruding tooth 212 contacts with the side of the second container 250 facing the first container 240; this reduces the contact area between second casing 250 and rack 210, further reduces the frictional resistance that rack 210 receives when moving relative to drive casing 230, and ensures smooth movement of rack 210.

It should be noted that the number of the first teeth 252 and the second teeth 212 can be selected according to the requirement, for example: one, two, three, etc., without specific limitation thereto.

When the air conditioner 010 of the embodiment is in use, the gear 220 can be driven to rotate by the motor 300, so that the rack 210 is driven to extend or retract relative to the installation cavity 130 by the rotating gear 220, and the air deflector 112 is driven to rotate by the rack 210, so as to adjust the air outlet direction.

In summary, the air guiding device 100 of the air conditioner 010 of the present invention can smoothly drive the air guiding plate 112, thereby improving user experience.

Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the utility model as defined in the appended claims.
