[0037] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0038] In combination with Figures 1-15As shown, the air outlet assembly 10 provided by the embodiment of the present disclosure comprises a fixed ring 100, a plurality of first baffles 400, a plurality of second baffles 500 and a driving ring 200. The fixed ring 100 is provided with a first air outlet. The fixed ring 100 is provided with a plurality of first pivot portions 110 and a plurality of second pivot portions 130 along the circumference of the first air outlet. The plurality of second pivot portions 130 are located outside the plurality of first pivot portions 110. The plurality of first baffles 400 are connected to the fixed ring 100 through the plurality of first pivot portions 110 in one-to-one correspondence and are rotatable. The second end of each first baffle 400 is movable along the direction close to or away from the axis of the first air outlet. When the second end of each first baffle 400 is rotated inward to a first position, the plurality of first baffles 400 are gathered into a conical cylinder with two open ends to open the first air outlet at the minimum opening degree. When the second end of each first baffle 400 is moved outward to a second position, the first air outlet is opened at the maximum opening degree. The plurality of second baffles 500 are connected to the fixed ring 100 through the plurality of second pivot portions 130 in one-to-one correspondence and are located outside the plurality of first baffles 400. The first end of each second baffle 500 is rotatably connected to the fixed ring 100 so that the second end is movable along the direction close to or away from the axis of the first air outlet. When the second end of each first baffle 400 is moved inward to the first position, the plurality of second baffles 500 are gathered inward. When the second end of each first baffle 400 is moved outward to the second position, each second baffle 500 is located between two adjacent first baffles 400. The driving ring 200 is coaxial with the fixed ring 100 and is rotatable relative to the fixed ring 100. The driving ring 200 is drivingly connected to the plurality of first baffles 400 and the plurality of second baffles 500. When the driving ring 200 rotates, the plurality of first baffles 400 and the plurality of second baffles 500 are driven to rotate.

[0039] The air outlet assembly 10 provided by the embodiment of the present disclosure comprises a base plate 11 and a plurality of first baffles 400. The base plate 11 is provided with a first air outlet in the middle. The plurality of first baffles 400 are connected to the base plate 11 and are distributed along the circumference of the first air outlet.

[0040] Taking one of the first baffles 400 as an example, the first end of the first baffle 400 is rotatably connected to the base plate 11. The axis around which the first baffle 400 rotates is parallel to the plane in which the first air outlet is located. When the first baffle 400 rotates, the second end is movable along the direction close to or away from the axis of the first air outlet.

[0041] When the plurality of first baffles 400 are all moved to the first position in the direction close to the axis of the first air outlet, the second ends of the plurality of first baffles 400 are gathered into a conical cylinder with two open ends. The end with a larger cross section of the conical cylinder is the first end, and the end with a smaller cross section is the second end. The first end of the conical cylinder is in abutment with the first air outlet of the bottom disc 11, and the second end of the conical cylinder serves as the air outlet of the air outlet assembly 10 as a whole. At this time, the air outlet cross section of the air outlet assembly 10 is reduced, and the air entering the conical cylinder is blown to a farther distance under the gathering and guiding effect of the plurality of first baffles 400, thereby realizing convergent telefocus air supply.

[0042] It should be noted that if only the cross section of the air outlet is reduced, the flow rate of the air at the air outlet is high, but the airflow is turbulent, and a lot of kinetic energy is lost due to molecular collision near the air outlet, so the air supply distance is short. However, using the air outlet assembly 10 provided by the embodiment of the present disclosure, under the gathering of the plurality of first baffles 400, each first baffle 400 plays a flow guiding role, and the air can form a laminar flow under the wall effect of the first baffle 400, so the energy loss is small during movement, thereby the air can be blown to a farther position.

[0043] When the plurality of first baffles 400 are all moved to the second position in the direction away from the axis of the first air outlet, the second ends of the plurality of first baffles 400 are spread apart. The projection of the second end of each first baffle 400 on the plane of the first air outlet is located outside the first air outlet. At this time, the air outlet of the bottom disc 11 serves as the air outlet of the air outlet assembly 10 as a whole, and the air outlet cross section of the air outlet assembly 10 is large. The air is directly blown out through the air outlet of the bottom disc 11 and is not disturbed by the plurality of first baffles 400, so the air volume of the air conditioner is large.

[0044] It should be noted that when the plurality of first baffles 400 are moved between the first position and the second position, the projection of the second end of the plurality of first baffles 400 on the plane of the air outlet is located inside the first air outlet. The plurality of first baffles 400 are gathered but cannot be enclosed into a closed conical cylinder. At this time, the first air outlet of the bottom disc 11 serves as the air outlet of the air outlet assembly 10 as a whole, and the second end of the plurality of first baffles 400 is located on the air outlet path to disturb the airflow. The air after being disturbed by the plurality of first baffles 400 is blown to a short distance and has a soft wind feeling, that is, the air supply is realized by sharp-piercing disturbance.

[0045] Using the air outlet assembly 10 disclosed in the present application, the air supply distance and the wind feeling strength can be adjusted by the movement of the plurality of first baffles 400, and the air outlet form is various; the positions of the plurality of first baffles 400 can be continuously changed, and the air supply distance and the wind feeling strength can be steplessly adjusted, so as to meet the individualized needs of users in different use scenarios.

[0046] When the plurality of first baffles 400 are combined into a conical barrel, a gap is easily formed between two adjacent first baffles 400. When the plurality of first baffles 400 are rotated to the second position, a larger gap is formed between two adjacent first baffles 400. This will affect the air outlet effect of the air outlet assembly 10 to some extent. Therefore, the air outlet assembly 10 is also provided with a plurality of second baffles 500 to shield the gap between the plurality of first baffles 400.

[0047] Specifically, the air outlet assembly 10 is provided with two circles of baffles, which are the plurality of first baffles 400 of the inner circle and the plurality of second baffles 500 of the outer circle. The plurality of second baffles 500 are also distributed along the circumference of the first air outlet, and each second baffle 500 is rotatably connected to the bottom disc 11, and the second end of each second baffle 500 can move in the direction of approaching or moving away from the axis of the air outlet.

[0048] When the plurality of first baffles 400 move inward to the first position, a first conical barrel is formed, and when the plurality of second baffles 500 move inward to the first position, a second conical barrel is formed, and the second conical barrel is located in the outer circle of the first conical barrel. At this time, each second baffle 500 shields the joint seam between two adjacent first baffles 400. With such a setting form, air leakage at the joint position of two adjacent first baffles 400 can be further avoided.

[0049] When the plurality of first baffles 400 move outward to the second position, they are enclosed into a cylindrical shape, and there is a gap between two adjacent first baffles 400. When the plurality of second baffles 500 move outward to the second position, they are enclosed into a cylindrical shape, and each second baffle 500 is used to shield the gap between two adjacent first baffles 400. In this way, the first baffles 400 and the second baffles 500 are enclosed into a closed air guide barrel. In this way, the air guide effect of the air outlet assembly 10 when the plurality of first baffles 400 are in the second position can be improved.

[0050] When the plurality of first baffles 400 are between the first position and the second position, the projection of the second end of the first baffle 400 on the plane of the first air outlet is located within the first air outlet, and the second end of the first baffle 400 plays a role of disturbing flow. At this time, the projection of the second end of the second baffle 500 on the plane of the first air outlet is also located within the first air outlet, and the second end of the second baffle 500 also plays a role of disturbing flow. In this way, the effect of the air outlet assembly 10 can be further improved.

[0051] The driving ring 200 simultaneously drives the plurality of first baffles 400 and the plurality of second baffles 500 to rotate, which not only simplifies the driving structure of the air outlet assembly 10 and reduces the volume of the air outlet assembly 10, but also improves the synchronization of the movement of the plurality of first baffles 400 and the plurality of second baffles 500.

[0052] Optionally, the driving ring 200 comprises a plurality of first driving portions 210 and a plurality of second driving portions 220, the first baffle 400 is provided with a first driving matching portion 420 matched with the first driving portion 210, the second baffle 500 is provided with a second driving matching portion 520 matched with the second driving portion 220, and the second ends of the plurality of first baffles 400 and the second ends of the plurality of second baffles 500 are driven to move along the direction close to or away from the axis of the first air outlet when the driving ring 200 rotates. As an implementation form, the first driving portion 210 comprises a first guide slot 211, the second driving portion 220 comprises a second guide slot 221, the first driving matching portion 420 comprises a first driving pin 421, and the second driving matching portion 520 comprises a second driving pin 521. The driving ring 200 is provided with a plurality of first guide slots 211 and a plurality of second guide slots 221, the plurality of first baffles 400 are each provided with a first driving pin 421, the plurality of second baffles 500 are each provided with a second driving pin 521, the plurality of first guide slots 211 and the plurality of first driving pins 421 are matched one by one, the plurality of second guide slots 221 and the plurality of second driving pins 521 are matched one by one, and the second ends of the plurality of first baffles 400 and the second ends of the plurality of second baffles 500 are driven to move along the direction close to or away from the axis of the first air outlet when the driving ring 200 rotates.

[0053] The driving ring 200 and the plurality of first baffles 400 are drivingly connected through the first guide slot 211 and the first driving pin 421, so that the circumferential motion of the driving ring 200 can be conveniently converted into the rotation of the first baffle 400. When the driving ring 200 rotates, the position of the matching of the first guide slot 211 and the first driving pin 421 changes, thereby driving the first driving pin 421 to rotate around the first pivot portion 110. The driving ring 200 and the plurality of second baffles 500 are drivingly connected through the second guide slot 221 and the second driving pin 521, so that the circumferential motion of the driving ring 200 can be conveniently converted into the rotation of the second baffle 500. When the driving ring 200 rotates, the position of the matching of the second guide slot 221 and the second driving pin 521 changes, thereby driving the first driving pin 421 to rotate around the first pivot portion 110. With such a setting form, the driving of the driving ring 200 on the plurality of first baffles 400 and the plurality of second baffles 500 is facilitated. The first guide slot 211 is used to drive the first baffle 400 to rotate, and the second guide slot 221 is used to drive the second baffle 500 to rotate. The matching of the second driving pin 521 and the second guide slot 221 can refer to the matching of the first driving pin 421 and the first guide slot 211. With such a setting form, the plurality of first baffles 400 and the plurality of second baffles 500 are simultaneously driven to rotate when the driving ring 200 rotates, and the integration degree of the air outlet assembly 10 is improved.

[0054] Optionally, the second guide slot 221 gradually increases in distance from the first air outlet from the first end to the second end; the second drive pin 521 extends into the second guide slot 221, and when the drive ring 200 rotates in the first direction, the distance of the second drive pin 521 from the first air outlet increases, thereby driving the second end of the first baffle 400 to approach the axis of the first air outlet.

[0055] Optionally, when the plurality of first baffles 400 and the plurality of second baffles 500 are moved to the second position, the side edges of the plurality of first baffles 400 and the side edges of the plurality of second baffles 500 are spliced.

[0056] In the thickness direction of the first baffle 400 or the second baffle 500, the first baffle 400 and the second baffle 500 partially overlap. In this way, on the one hand, the overall thickness of the plurality of first baffles 400 and the plurality of second baffles 500 after splicing can be reduced, thereby increasing the air outlet cross section, and on the other hand, the structural strength of the plurality of first baffles 400 and the plurality of second baffles 500 when spliced can be improved, thereby reducing the vibration of the first baffle 400 and the second baffle 500. In addition, the splicing form of the first baffle 400 and the second baffle 500 can also improve the air tightness of the air outlet assembly 10, thereby improving the air guiding effect of the air outlet assembly 10.

[0057] Optionally, the distance of the first guide slot 211 from the first air outlet gradually increases from the first end to the second end; the distance of the second guide slot 221 from the first air outlet gradually increases from the first end to the second end.

[0058] Optionally, the distance of the first guide slot 211 from the first air outlet gradually increases from the first end to the second end; the second drive pin 521 extends into the second guide slot 221, and when the drive ring 200 rotates in the first direction, the distance of the second drive pin 521 from the first air outlet increases, thereby driving the second end of the first baffle 400 to approach the axis of the first air outlet.

[0059] When the driving ring 200 rotates, the first guide groove 211 rotates relative to the first driving pin 421, and the first driving pin 421 slides relative to the first guide groove 211 under the limitation of the first blocking piece 400 by the first pivot part 110. When the driving ring 200 rotates to the first direction, the first end of the first guide groove 211 gradually changes to the second end of the first guide groove 211 cooperating with the first driving pin 421. Under the limitation of the first guide groove 211, the distance between the first driving pin 421 and the axis of the air outlet gradually increases. The first blocking piece 400 takes the rotation axis as the fulcrum, takes the first driving pin 421 as one end of the lever, and takes the second end of the first blocking piece 400 as the other end of the lever. When the distance between the first driving pin 421 and the axis of the air outlet gradually increases, the distance between the second end of the first blocking piece 400 and the axis of the air outlet gradually decreases. The plurality of first blocking pieces 400 move in the same way, and the second ends of the plurality of first blocking pieces 400 converge inward to achieve the aggregated telephoto air outlet. When the driving ring 200 rotates to the second direction, the distance between the first driving pin 421 and the axis of the air outlet gradually decreases, and the second ends of the plurality of first blocking pieces 400 spread out to achieve the windless air outlet.

[0060] Optionally, the angle between the first guide groove 211 from the first end to the second end and the axis of the first air outlet gradually increases.

[0061] The first guide groove 211 has two opposite inner edges in the thickness direction of the first guide groove 211 along the axis of the first air outlet, and the included angle between the first guide groove 211 and the axis of the first air outlet refers to the included angle between the inner edge of the first guide groove 211 along the axis of the first air outlet and the axis of the first air outlet. If the two are parallel, the first driving pin 421 will interfere with the inner edge of the first guide groove 211 when it rotates. If a larger fitting allowance is provided between the first guide groove 211 and the first driving pin 421, it may cause the position of the first driving pin 421 to be unclear when the driving ring 200 rotates. Specifically, when the first baffle 400 is located at the first position, it blocks more air outlets, and at this time, the first driving pin 421 also tilts more. When the first baffle 400 is located at the second position, the length direction of the first baffle 400 is along the axis of the first air outlet, and at this time, the first driving pin 421 tilts less and is generally parallel to the axis of the first air outlet. The included angle between the first guide groove 211 and the air outlet gradually increases from the first end to the second end, and the degree of inclination of the first driving pin 421 during the rotation of the first baffle 400 is adapted to the degree of inclination of the first guide groove 211. In this way, on the one hand, the friction between the first guide groove 211 and the first driving pin 421 can be reduced, and on the other hand, the first driving pin 421 can be better rotated to a preset angle. Optionally, the distance between the second guide groove 221 and the first air outlet gradually increases from the first end to the second end; the second driving pin 521 extends into the second guide groove 221, and when the driving ring 200 rotates in the first direction, the distance between the second driving pin 521 and the first air outlet increases, thereby driving the second end of the first baffle 400 to approach the axis of the first air outlet.

[0062] Optionally, the fixed ring 100 is provided with a plurality of first avoiding grooves 141, and the plurality of first avoiding grooves 141 correspond one-to-one to the plurality of first baffles 400. The first driving pin 421 of the first baffle 400 extends into the first guide groove 211 of the driving ring 200 through the first avoiding groove 141.

[0063] Optionally, the fixed ring 100 is provided with a plurality of first avoiding grooves 141, and the plurality of first avoiding grooves 141 correspond one-to-one to the plurality of first baffles 400. The first driving pin 421 of the first baffle 400 extends into the first guide groove 211 of the driving ring 200 through the first avoiding groove 141.

[0064] When the first baffle 400 rotates, the first driving pin 421 also rotates, and the first driving pin 421 extends into the first guide groove 211 of the driving ring 200 through the avoiding groove provided in the fixed ring 100. With such a setting form, the first driving pin 421 does not need to protrude out of the driving ring 200 to cooperate with the first guide groove 211 of the driving ring 200, thereby simplifying the structure of the air outlet assembly 10.

[0065] Optionally, the length direction of the first avoiding groove 141 is along the radial direction of the fixed ring 100, and the width is adapted to the size of the first driving pin 421.

[0066] The first driving pin 421 moves along the radial direction of the fixing ring 100 when rotating, and the length direction of the first avoiding slot 141 is along the radial direction of the fixing ring 100, so that a rotating space is left for the rotation of the first driving pin 421. The width of the first avoiding slot 141 is matched with the size of the first driving pin 421, so that the movement of the first driving pin 421 is limited to the radial direction of the mounting ring 300, thereby avoiding the friction between the first guide slot 211 and the first driving pin 421 from driving the first driving pin 421 to rotate along the circumferential direction of the fixing ring 100 when the driving ring 200 rotates. In this way, the reliability of the air outlet assembly 10 in operation can be improved.

[0067] Optionally, the fixing ring 100 is provided with a plurality of second avoiding slots 142, and the plurality of second avoiding slots 142 correspond to the plurality of first blocking pieces 400 one by one. The second driving pin 521 of the second blocking piece 500 extends into the second guide slot 221 of the driving ring 200 through the second avoiding slot 142.

[0068] The fixing ring 100 is provided with a plurality of second avoiding slots 142, and the plurality of second avoiding slots 142 are located at the outer circle of the plurality of first avoiding slots 141. The second driving pin 521 extends into the second guide slot 221 through the second avoiding slot 142. The second driving pin 521 rotates when the second blocking piece 500 rotates, and the second driving pin 521 extends into the second guide slot 221 of the driving ring 200 through the second avoiding slot 142 of the fixing ring 100. By adopting this arrangement form, the second driving pin 521 does not need to protrude from the driving ring 200 to cooperate with the second guide slot 221 of the driving ring 200, thereby simplifying the structure of the air outlet assembly 10.

[0069] Optionally, when the first blocking piece 400 and the second blocking piece 500 are rotated to the second position, the second blocking piece 500 protrudes from the first blocking piece 400 in the air outlet direction.

[0070] The height of the second blocking piece 500 extending from the fixing ring 100 is greater than the height of the first blocking piece 400 extending from the fixing ring 100. When the plurality of first blocking pieces 400 are gathered inward, the length of the second blocking piece 500 is relatively long, so that the gap between the first blocking pieces 400 can be better blocked. When the plurality of first blocking pieces 400 are located between the first position and the second position and perform the sharp-piercing flow interference air supply, the length of the second blocking piece 500 is relatively long, and the first blocking piece 400 overlaps with the first blocking piece 400 in the plane where the first air outlet is located, so that the plurality of second blocking pieces 500 and the plurality of first blocking pieces 400 can better jointly play the role of sharp-piercing flow interference. When the plurality of first blocking pieces 400 are located at the second position, the length of the plurality of second blocking pieces 500 exceeds that of the plurality of first blocking pieces 400. In this way, the change of the flow passage cross section when the air is blown out through the air outlet assembly 10 can be certain excess, so that a relatively strong turbulent flow is avoided at the air outlet, thereby improving the air outlet effect of the air outlet assembly 10.

[0071] Optionally, the outer ring of the fixed ring 100 is outwardly convex to form an annular step 180, the plurality of second pivoting portions 130 are arranged above the annular step 180, and the plurality of first pivoting portions 110 are arranged at the inner ring of the fixed ring 100.

[0072] The outer ring of the fixed ring 100 is used to connect the plurality of second baffles 500, and the inner ring is used to connect the plurality of first baffles 400. When the plurality of first baffles 400 are spliced, gaps are easily generated near the fixed ring 100, which include the gaps between adjacent two first baffles 400 and the gaps between the first baffles 400 and the fixed ring 100. Therefore, the fixed ring 100 is provided with the annular step 180, the outer ring of the fixed ring 100 is higher than the inner ring of the fixed ring 100, that is, the plurality of first connecting members 120 are arranged below the step, and the plurality of second connecting members are arranged above the step. The gaps of the plurality of first baffles 400 near the fixed ring 100 are shielded by the sidewall of the annular step 180. By adopting such a setting form, the air-tightness of the plurality of first baffles 400 when spliced can be improved, thereby improving the air outlet effect of the air outlet assembly 10. In addition, the pivoting position of the first baffle 400 is below the step, and the pivoting position of the second baffle 500 is above the step, and even if the distance between them is close, they are not easy to interfere with rotation. The annular step 180 can reduce the distance between the first baffle 400 and the second baffle 500, thereby improving the air-tightness of the air outlet assembly 10.

[0073] Optionally, the first pivoting portion 110 of the annular step 180 protrudes in the air outlet direction.

[0074] The height of the second baffle 500 extending from the fixed ring 100 is greater than the height of the first baffle 400 extending from the fixed ring 100. When the plurality of first baffles 400 are gathered inward, the length of the second baffle 500 is longer, which can better shield the gaps between the first baffles 400. When the plurality of first baffles 400 are located between the first position and the second position to perform the sharp-pike flow interference air supply, the length of the second baffle 500 is longer, and the first baffle 400 intersects and overlaps the plane where the first air outlet is located, so that the plurality of second baffles 500 and the plurality of first baffles 400 can better jointly play the role of sharp-pike flow interference. When the plurality of first baffles 400 are located at the second position, the plurality of second baffles 500 are longer than the plurality of first baffles 400. In this way, the change of the flow passage cross section when air is blown out through the air outlet assembly 10 has a certain excess, avoiding the formation of strong turbulence at the air outlet, which can improve the air outlet effect of the air outlet assembly 10.

[0075] Optionally, the middle part of the wind blocking portion 411 is convex to the first air outlet.

[0076] The middle portion of the wind deflector 411 is convex to the first air outlet, that is, the angle between the cone barrel and the axis of the first air outlet gradually decreases from the first end to the second end. In the cone barrel, the increase of air flow rate is more in the portion close to the first end and less in the portion close to the second end. In the front section of the cone barrel, the turbulence formed by throttling and acceleration is more, and in the rear section of the cone barrel, the change of speed is less, and the wall effect at the rear end of the cone barrel rectifies to reduce turbulence and increase laminar flow. After the air is blown out of the first cone barrel, it can be blown to a farther distance. With such a setting form, the air supply distance of the air outlet assembly 10 can be further improved.

[0077] Optionally, the inner side of the plate body 410 is configured with a wind guide protrusion 413 extending along the length direction of the first baffle 400.

[0078] The wind guide protrusion 413 on the inner surface of the plate body 410 is wedge-shaped or triangular, and its width gradually decreases from the first end to the second end of the plate body 410. When the plurality of first baffles 400 are spliced, the two adjacent wind guide protrusions 413 form a wind guide groove. The portion of the air flowing in the cone barrel close to the inner wall of the cone barrel is divided into multiple streams flowing along multiple wind guide grooves by the wind guide protrusions 413. Under the guidance of the multiple first wind guide grooves, the air as a whole moves in the air outlet direction even if there is a certain vortex. In this way, the influence of the air close to the inner wall of the cone barrel on the flow of other parts of the air can be reduced, the kinetic energy loss of the air in the cone barrel can be reduced, and thus the air supply distance of the air outlet assembly 10 can be improved.

[0079] Optionally, the plate body 410 is configured with two wind guide protrusions 413, and a wind guide groove is formed between the two adjacent wind guide protrusions 413.

[0080] The plate body 410 is configured with two wind guide protrusions 413, and more wind guide grooves can be formed on the inner wall of the cone barrel. In this way, the kinetic energy loss of the air in the cone barrel can be further reduced, and thus the air supply distance of the air outlet assembly 10 can be improved.

[0081] Optionally, the two wind guide protrusions 413 are respectively close to the two side edges of the plate body 410, one side edge of the wind guide protrusion 413 serves as a first splicing portion 414, and when the plurality of first baffles 400 are spliced, the wind guide protrusions 413 of the two adjacent first baffles 400 are spliced.

[0082] The two wind guide protrusions 413 of the plate body 410 are close to the two side edges, and the wind guide protrusions 413 simultaneously serve as the structural reinforcement of the first plate body 410. When the plurality of first baffles 400 are spliced, the first baffles 400 are not easy to deform; when the air flows through the cone barrel, the first baffles 400 are not easy to vibrate.

[0083] The air guide protrusions 413 are preferably flush with the side edges of the plate body 410. In this way, the plate body 410 is thicker at the side edges. The thickened side edges serve as the first joint 414, and when multiple first baffles 400 are joined together, the first baffles 400 are less likely to deform due to contact with each other, and the side edges of the plate body 410 are less likely to be misaligned or have gaps when two adjacent first baffles 400 are joined together.

[0084] Optionally, the outer side of the plate body 410 is provided with a wedge-shaped protrusion 440.

[0085] The outer side of the plate body 410 is provided with a wedge-shaped protrusion 440, and in a cross-sectional view of the first baffle 400, the air guide protrusion 413 on the inner side and the wedge-shaped protrusion 440 on the outer side of the plate body 410 form a structure with multiple bends, which further improves the structural strength of the plate body 410.

[0086] Optionally, the width of the wedge-shaped protrusion 440 gradually increases from the first end to the second end of the plate body 410, the width of the air guide groove gradually increases from the first end to the second end of the plate body 410, and the wedge-shaped protrusion 440 corresponds to the air guide groove.

[0087] The width of the air guide groove gradually increases from the first end to the second end, and the width of the two air guide protrusions 413 adjacent to the air guide groove gradually decreases from the first end to the second end of the plate body 410. The width of the air guide groove gradually increases, and the air flowing in the air guide groove has a gradually expanding cross-section. In this way, the vortex formed by the air in the air guide groove and the wall of the air guide groove occurs as much as possible in the air guide groove, reducing the kinetic energy loss caused by the vortex contacting with the air in other positions. The wedge-shaped protrusion 440 corresponds to the air guide groove, so that the thickness of the plate body 410 is uniform throughout the plane. In this way, the structural strength of the first baffle 400 is improved while the weight of the first baffle 400 is reduced, and the cost of the air outlet assembly 10 is reduced.

[0088] Optionally, the rotation shaft is arranged at the end of the mounting portion 412 away from the air guide portion 411.

[0089] The rotation shaft is arranged at the end of the mounting portion 412 away from the air guide portion 411, and when the first baffle 400 rotates, the rotation of the mounting portion 412 and the air guide portion 411 is all located on one side of the rotation shaft 430, so that the first baffle 400 is less likely to interfere with the chassis 11 when it rotates.

[0090] Optionally, the fixing ring 100 is provided with a plurality of first connecting pieces 120 along the circumference of the first air outlet, both ends of the first connecting piece 120 are provided with shaft holes, the axis of the shaft hole is parallel to the plane where the first air outlet is located, and every two adjacent first connecting pieces 120 are taken as a first pivot part 110, and both ends of the rotating shaft of the first baffle 400 are inserted into the two opposite shaft holes of the adjacent two first connecting pieces 120.

[0091] By fixing both ends of the rotating shaft of the first baffle 400 through the adjacent two first connecting pieces 120, the first baffle 400 is not easy to deviate when rotating; both ends of each first connecting piece 120 are connected with a first baffle 400, the number of the connecting pieces is equal to the number of the first baffles 400, and the structure of the fixing ring 100 is simple and the processing difficulty is low.

[0092] Optionally, the shaft hole is provided with a clamping gap in the radial direction, and the rotating shaft of the first baffle 400 is clamped into the shaft hole along the clamping gap.

[0093] If both ends of the rotating shaft are inserted into the shaft hole along the axial direction of the rotating shaft, the rotating shaft will be elastically deformed during assembly, or the shaft hole needs to leave an assembly allowance for the rotating shaft. In this case, the first baffle 400 may deviate along the axial direction of the rotating shaft when rotating. The shaft hole is provided with a clamping gap in the radial direction, and the width of the clamping gap is less than the diameter of the rotating shaft. When assembling the first baffle 400, the rotating shaft is clamped into the shaft hole along the radial direction from the clamping gap, and then gap fits with the shaft hole to realize the rotatable connection of the first baffle 400. By adopting such a setting form, the assembly of the first baffle 400 can be facilitated and the installation accuracy of the first baffle 400 can be improved.

[0094] Optionally, the first connecting piece 120 is provided with a first shaft hole and a second shaft hole, and the second included angle is between the first shaft hole and the second shaft hole.

[0095] The plurality of first baffles 400 can be gathered to form a conical barrel, and the rotating shafts of the plurality of first baffles 400 form a regular polygon, so that a larger area shape can be enclosed with less material. The rotating shaft of the first baffle 400 is a side of the regular polygon, and there is a certain included angle a between the adjacent two rotating shafts. In the case that the number of the first baffles 400 is n, the included angle a = 180°-(360° / n). Correspondingly, the second included angle between the first shaft hole and the second shaft hole is also a, which can better constrain the rotating shaft of the first baffle 400, so as to make the plurality of first baffles 400 enclose a conical barrel with a larger air guide cross section at the bottom end.

[0096] Optionally, the first shaft hole and the second shaft hole are connected.

[0097] In this way, the injection difficulty of the first connecting piece 120 is reduced, and the injection material of the first connecting piece 120 is reduced, thereby reducing the cost of the air outlet assembly 10.

[0098] Optionally, the two side ends of the first baffle 400 are provided with first splicing portions 414, and each two adjacent first baffles 400 are spliced through the two first splicing portions 414.

[0099] When the plurality of first baffles 400 are all moved inward to the first position, the plurality of first baffles 400 are spliced into a conical cylinder. If there is a gap between each two adjacent first baffles 400, the air leakage in the gap will affect the air supply effect of the air outlet assembly 10. The two ends of each first baffle 400 are provided with first splicing portions 414, and each two adjacent first baffles 400 are spliced through the first splicing portions 414. In this way, the air supply effect of the air outlet assembly 10 is improved, and the noise generated by the air flowing through the gap between each two adjacent first baffles 400 is reduced.

[0100] Optionally, the outer side of the first baffle 400 is provided with a wedge-shaped protrusion 440, and the wedge-shaped protrusion 440 is embedded between each two adjacent second baffles 500 when the first baffle 400 and the second baffle 500 are both rotated to the second position.

[0101] When the plurality of first baffles 400 and the plurality of second baffles 500 are both moved to the second position, the air outlet is opened at the maximum opening degree, and at this time, the plurality of first baffles 400 and the plurality of second baffles 500 are enclosed into a cylindrical shape. The outer side of the first baffle 400 is provided with a wedge-shaped protrusion 440, and the two side edges of the wedge-shaped protrusion 440 abut against each two adjacent second baffles 500, respectively. In this way, the wedge-shaped protrusion 440 can position the two adjacent second baffles 500. The first baffle 400 in the inner ring and the second baffle 500 in the outer ring are locked through the wedge-shaped protrusion 440, so that the first baffle 400 or the second baffle 500 is prevented from shaking.

[0102] Optionally, in the case where the bottom disc 11 comprises the fixed ring 100 and the driving ring 200, one side of the fixed ring 100 is provided with a plurality of second pivot portions 130 which are circumferentially spaced apart, the plurality of second pivot portions 130 are located in the outer ring of the plurality of first pivot portions 110, and the plurality of second baffles 500 are one-to-one correspondingly connected to the fixed ring 100 through the plurality of second pivot portions 130 in a rotatable manner; the driving ring 200 is further provided with a plurality of second driving portions 220, the plurality of second baffles 500 are provided with second driving matching portions 520, the plurality of second driving portions 220 and the plurality of second driving matching portions 520 are one-to-one correspondingly matched, and the driving ring 200 drives the plurality of second baffles 500 to rotate when the driving ring 200 rotates.

[0103] The fixed ring 100 is provided with a plurality of first pivot portions 110 and a plurality of second pivot portions 130 located outside the plurality of first pivot portions 110. The plurality of first pivot portions 110 are used to rotatably connect the plurality of first baffles 400 to the fixed ring 100, and the plurality of second pivot portions 130 are used to rotatably connect the plurality of second baffles 500 to the fixed ring 100. Thus, the plurality of first baffles 400 and the plurality of second baffles 500 can be installed and positioned by the fixed ring 100, and the structure of the air outlet assembly 10 is simplified.

[0104] The driving ring 200 is provided with a plurality of second driving portions 220, and each of the second baffles 500 is provided with a second driving matching portion 520. The plurality of second driving portions 220 and the plurality of second driving matching portions 520 correspond to each other, and the driving ring 200 drives the plurality of first baffles 400 and the plurality of second baffles 500 to rotate simultaneously. In this way, the plurality of first baffles 400 and the plurality of second baffles 500 can be driven to rotate simultaneously by the driving ring 200, which is conducive to the synchronous movement of the plurality of first baffles 400 and the plurality of second baffles 500, and the structure of the air outlet assembly 10 is simplified.

[0105] Optionally, the air outlet assembly 10 further comprises a mounting ring 300 coaxial with the fixed ring 100. The mounting ring 300 is arranged opposite to the fixed ring 100 to form a driving space, and the driving ring 200 is rotatably arranged in the driving space.

[0106] The mounting ring 300 is used to fix the air outlet assembly 10 to a predetermined mounting position, such as an air outlet of a cabinet-type air conditioner. The bottom plate 11 is sequentially provided with the mounting ring 300, the driving ring 200, and the fixed ring 100 along the air outlet direction. The driving ring 200 is located between the mounting ring 300 and the fixed ring 100. When the driving ring 200 drives the plurality of first baffles 400 to rotate, the movement of the driving ring 200 is not easy to interfere with the air outlet assembly 10 or other parts of the air conditioner. The mounting ring 300 and the fixed ring 100 form the driving space, so that the air outlet assembly 10 has a neat appearance.

[0107] Optionally, the mounting ring 300 is provided with a third avoiding slot 341. The length direction of the third avoiding slot 341 is along the radial direction of the mounting ring 300, and the width of the third avoiding slot 341 is adapted to the size of the first driving pin 421.

[0108] In this way, the third avoiding slot 341 of the mounting ring 300 and the first avoiding slot 141 of the fixing ring 100 jointly limit the movement of the first driving pin 421 in the radial direction of the fixing ring 100. With this arrangement, the movement of the first driving pin 421 in the circumferential direction of the fixing ring 100 can be further avoided. Alternatively, the fixing ring 100 is provided with a plurality of second pivot portions 130 spaced apart in the circumferential direction of the first air outlet, the plurality of second pivot portions 130 are located outside the plurality of first pivot portions 110, and the plurality of second blocking pieces 500 are rotatably connected to the fixing ring 100 one by one through the plurality of second pivot portions 130.

[0109] Alternatively, the mounting ring 300 is provided with a plurality of fourth avoiding slots 342 corresponding to the plurality of second avoiding slots 142, and the second driving pin 521 extends into the fourth avoiding slot 342 through the second guide slot 221.

[0110] The fourth avoiding slot 342 and the second avoiding slot 142 cooperate to limit the movement of the second driving pin 521 in the circumferential direction of the fixing ring 100. In this way, the rotation of the second driving pin 521 can be better limited in the preset rotation plane, and the local deformation or fracture of the second driving pin 521 due to excessive force can be avoided.

[0111] Alternatively, the mounting ring 300 is provided with a first sliding groove 320, the fixing ring 100 is provided with a second sliding groove 160 corresponding to the first sliding groove 320, and the driving ring 200 is provided with a sliding column 230, both ends of the sliding column 230 extend beyond two sides of the driving ring 200 and extend into the first sliding groove 320 and the second sliding groove 160, respectively.

[0112] The driving ring 200 rotates in the driving space. If the driving ring 200 and the mounting ring 300 or the fixing ring 100 are in surface friction, the large friction will affect the rotation of the driving ring 200. The mounting ring 300 is provided with a first sliding groove 320, and the fixing ring 100 is provided with a second sliding groove 160 corresponding to the first sliding groove 320. Both the first sliding groove 320 and the second sliding groove 160 are arc-shaped sliding grooves. The driving ring 200 is further provided with a sliding column 230, both ends of the sliding column 230 extend beyond two sides of the driving ring 200 and extend into the first sliding groove 320 and the second sliding groove 160, respectively. In this way, on the one hand, the sliding column 230 and the sliding groove cooperate to define a sliding track for the driving ring 200, which is conducive to the rotation of the driving ring 200; on the other hand, the sliding column 230 and the sliding groove cooperate to reduce the rotation friction of the driving ring 200, so that the driving ring 200 can rotate more smoothly. In addition, both ends of the sliding column 230 extend into the first sliding groove 320 and the second sliding groove 160, respectively, which is conducive to maintaining the relative distance between the driving ring 200 and the mounting ring 300 and the fixing ring 100. With this arrangement, the concentricity and flatness of the driving ring 200 during rotation can be improved, which is conducive to the synchronous rotation of the plurality of first blocking pieces 400 driven by the driving ring 200.

[0113] Optionally, when the sliding column 230 is located at the first end of the first sliding groove 320, the second ends of the plurality of first flaps 400 turn inward to the first position and gather into a tapered cylinder with both ends open, at this time the first air outlet is opened with the minimum opening degree; when the sliding column 230 is located at the second end of the first sliding groove 320, the second ends of the plurality of first flaps 400 turn outward to the second position to make the first air outlet open with the maximum opening degree.

[0114] After the plurality of first flaps 400 are all turned inward to the first position, if the driving ring 200 continues to rotate, it can cause the first flaps 400 to deform or flash, affecting the air outlet effect of the air outlet assembly 10. Therefore, the movement of the first flaps 400 needs to be limited. Since the rotation of the first flaps 400 is driven by the rotation of the driving ring 200, limiting the rotation of the driving ring 200 also simultaneously achieves the rotation limitation of the first flaps 400. Specifically, the first flaps 400 rotate between the first position and the second position, and correspondingly, the sliding column 230 slides between the first end and the second end of the first sliding groove 320. That is, the two ends of the first sliding groove 320 serve as the sliding limiting portion of the sliding column 230. With such a setting form, the first flaps 400 can be accurately moved to the first position or the second position, improving the accuracy of the movement control of the air outlet assembly 10 on the first flaps 400.

[0115] Optionally, when the sliding column 230 is located at the first end of the second sliding groove 160, the second ends of the plurality of first flaps 400 turn inward to the first position and gather into a tapered cylinder with both ends open, at this time the first air outlet is opened with the minimum opening degree; when the sliding column 230 is located at the second end of the second sliding groove 160, the second ends of the plurality of first flaps 400 turn outward to the second position to make the first air outlet open with the maximum opening degree.

[0116] Limiting the rotation of the driving ring 200 by the second sliding groove 160 and limiting the rotation of the driving ring 200 by the first sliding groove 320 can achieve the same effect.

[0117] Optionally, the side of the mounting ring 300 facing the fixed ring 100 is provided with a plurality of positioning bosses 330 along the circumference of the first air outlet, and the fixed ring 100 is provided with a plurality of positioning matching portions 170 corresponding to the positioning bosses 330, and the plurality of positioning matching portions 170 are one-to-one correspondingly lapped on the top of the positioning bosses 330.

[0118] The driving ring 200 rotates between the mounting ring 300 and the fixing ring 100, and a space is required between the mounting ring 300 and the fixing ring 100 for the rotation of the driving ring 200. Therefore, the mounting ring 300 is provided with a plurality of positioning bosses 330 spaced along the circumference thereof, and the fixing ring 100 is provided with a plurality of positioning matching portions 170 along the circumference thereof. The side of the positioning boss 330 facing the fixing ring 100 abuts against the side of the positioning matching portion 170 facing the mounting ring 300.

[0119] Optionally, the driving ring 200 is located inside the inner circle of the plurality of positioning bosses 330.

[0120] If the positioning boss 330 penetrates the driving ring 200, the driving ring 200 needs to be provided with a corresponding avoiding slot, which will affect the structural strength of the driving ring 200. Therefore, the driving ring 200 is located inside the inner circle of the plurality of positioning bosses 330. In this way, the positioning boss 330 and the positioning matching portion 170 will not interfere with the rotation of the driving ring 200, and the driving ring 200 does not need to be provided with an avoiding slot, and the structural strength is higher.

[0125] Optionally, the first blocking piece 400 includes a plate body 410, a rotating shaft, and a first driving pin 421, wherein the plate body 410 gradually decreases in width from a first end to a second end; the rotating shaft is arranged at the first end of the plate body 410; and the first driving pin 421 is arranged at the first end of the plate body 410 or the rotating shaft.

[0126] The plurality of first baffles 400 can be combined into a conical cylinder, and the width of the second end of each first baffle 400 is smaller than the width of the first end. Specifically, the first baffle 400 includes a plate body 410 as the main body of the first baffle 400, and the plate body 410 plays a role of enclosing and guiding wind when the plurality of first baffles 400 are combined. The width of the plate body 410 gradually decreases from the first end to the second end, so that the plurality of first baffles 400 can be combined into a sealed conical cylinder when gathered. A rotating shaft is arranged at the first end of the plate body 410, and the rotating shaft cooperates with the first pivot part 110 of the fixed ring 100 to rotatably connect the first baffle 400 to the fixed ring 100. The first driving pin 421 is connected to the first end of the plate body 410 or the rotating shaft at one end and extends into the first guide slot 211 at the other end. With such an arrangement, the driving ring 200 can drive the first baffle 400 to rotate.

[0127] Optionally, the plate body 410 includes a wind blocking part 411 and a mounting part 412, wherein the width of the wind blocking part 411 gradually decreases from the first end to the second end; and the mounting part 412 is connected to the first end of the baffle plate and has a first included angle with the wind blocking part 411.

[0128] The plate body 410 includes a wind blocking part 411 and a mounting part 412, and the wind blocking parts 411 of the plurality of first baffles 400 are combined into a conical cylinder, and the mounting part 412 is used to fix the first baffle 400 to the bottom disc 11.

[0129] The width of the wind blocking part 411 gradually decreases from the first end to the second end, which is conducive to the combination of the wind blocking parts 411 of the plurality of first baffles 400.

[0130] In the case where the plurality of first baffles 400 are combined into a conical cylinder, in the length direction, the wind blocking part 411 is generally along the axial direction of the first air outlet, and the mounting part 412 is generally along the radial direction of the first air outlet.

The mounting part 412 is attached to the bottom disc 11, and the fixing of the first baffle 400 can be achieved without opening a hole in the bottom disc 11, so that air leakage of the air outlet assembly 10 can be avoided. The mounting part 412 is attached to the bottom disc 11, and the contact area between them is large, so that the fixing effect of the bottom disc 11 on the first baffle 400 can be improved.

[0131] Optionally, the outer edge of the driving ring 200 is provided with a gear; and the air outlet assembly 10 further includes a driving gear 240 engaged with the gear of the driving ring 200, and the driving gear 240 drives the driving ring 200 to rotate when the driving gear 240 rotates.

[0132] The outer periphery of the driving ring 200 is provided with teeth. The driving ring 200 is driven to rotate and the driving ring 200 is in one plane, so that the thickness of the air outlet assembly 10 is reduced. The driving gear 240 is engaged with the teeth of the outer periphery of the driving ring 200. When the driving gear 240 rotates, the driving ring 200 rotates by a corresponding number of teeth. In this way, a smaller motor can also drive the driving ring 200, reducing the size of the air outlet assembly 10 and reducing the cost of the air outlet assembly 10.

[0133] Optionally, the first part of the outer periphery of the driving ring 200 is provided with teeth.

[0134] When the driving ring 200 drives the first baffle 400 to move between the first position and the second position, the angle of rotation of the driving ring 200 is fixed, and the outer periphery of the driving ring 200 is partially toothed. With this arrangement, the machining difficulty of the driving ring 200 is reduced. In addition, the driving ring 200 is partially toothed, so that even if the rotation of the driving motor is abnormal, the driving ring 200 will not rotate beyond its rotation range, thereby avoiding the rotation of the first baffle 400 beyond its rotation range. In this way, the safety of the air outlet assembly 10 is improved.

[0135] Optionally, the mounting ring 300 is provided with a first clamping portion 310 extending radially, and the fixing ring 100 is provided with a second clamping portion 150 extending radially. The first clamping portion 310 and the second clamping portion 150 define a gear mounting space.

[0136] Optionally, the mounting ring 300 is provided with a first clamping portion 310 extending radially outward, and the fixing ring 100 is provided with a second clamping portion 150 extending radially outward. The first clamping portion 310 and the second clamping portion 150 define a gear mounting space, and the driving gear 240 is arranged in the gear mounting space.

[0137] To realize the installation and positioning of the driving gear 240, the mounting ring 300 is provided with a first clamping portion 310 extending radially, and the fixing ring 100 is provided with a second clamping portion 150 extending radially. The first clamping portion 310 and the second clamping portion 150 define a gear mounting space. The gear mounting space is provided with a clearance opening facing the driving ring 200 to enable the driving gear 240 to engage with the driving ring 200. With this arrangement, the fixing of the driving gear 240 is facilitated. In addition, the first clamping portion 310 and the second clamping portion 150 correspond to each other and can serve as visual identification marks when the mounting ring 300 and the fixing ring 100 are connected, facilitating the assembly of the air outlet assembly 10.

[0138] Optionally, when the driving ring 200 rotates in the first direction, the plurality of first baffles 400 and the plurality of second baffles 500 rotate inward, and the plurality of first baffles 400 rotate ahead of the plurality of second baffles 500; when the driving ring 200 rotates in the second direction, the plurality of first baffles 400 and the plurality of second baffles 500 rotate outward, and the plurality of second baffles 500 rotate ahead of the plurality of first baffles 400.

[0139] When the driving ring 200 rotates in the first direction, the plurality of first baffles 400 and the plurality of second baffles 500 rotate inward, and the plurality of first baffles 400 rotate ahead of the plurality of second baffles 500. That is, when the plurality of first baffles 400 and the plurality of second baffles 500 rotate inward, the plurality of first baffles 400 rotate first, and the plurality of second baffles 500 rotate later. In this way, a wind dispersing layer is formed between the first baffles 400 of the inner ring and the first baffles 400 of the outer ring. Part of the air entering the air outlet assembly 10 from the first air outlet first passes through the air guiding gap between the adjacent two first baffles 400 to enter the wind dispersing layer between the first baffles 400 and the second baffles 500, and then passes through the air guiding gap between the adjacent two second baffles 500 to blow out. The turbulence of the plurality of first baffles 400 and the turbulence between the plurality of second baffles 500 have the wind dispersing layer as a buffer, and the air is mixed in the wind dispersing layer after being disturbed by the first baffles 400 and then blown out after being disturbed by the second baffles 500. By adopting such a setting form, the wind dispersing layer can be formed, so that the plurality of first baffles 400 and the plurality of second baffles 500 can better cooperate to realize the function of sharp-piercing turbulence.

[0140] Similarly, when the driving ring 200 rotates in the second direction, the plurality of first baffles 400 and the plurality of second baffles 500 rotate outward, and the plurality of second baffles 500 rotate ahead of the plurality of first baffles 400. When the plurality of first baffles 400 and the plurality of second baffles 500 rotate outward, the plurality of second baffles 500 rotate first, and the plurality of first baffles 400 rotate later. In this way, a wind dispersing layer is also formed between the first baffles 400 of the inner ring and the second baffles 500 of the outer ring, so that the plurality of first baffles 400 and the plurality of second baffles 500 can better cooperate to realize the function of sharp-piercing turbulence.

[0141] By adopting such a setting form, the plurality of first baffles 400 and the plurality of second baffles 500 have a certain time difference in movement, so that a wind dispersing layer can be formed between the plurality of first baffles 400 and the plurality of second baffles 500, and the plurality of first baffles 400 and the plurality of second baffles 500 can better cooperate to realize the function of sharp-piercing turbulence.

[0142] Optionally, the air outlet assembly 10 further comprises a wind blocking cylinder 600, which is arranged outside the plurality of first baffles 400 and the plurality of second baffles 500.

[0143] The bottom end of the wind deflector 600 is connected to the first air outlet, and the plurality of first baffles 400 and the plurality of second baffles 500 are located in the inner ring of the wind deflector 600. By providing the wind deflector 600, air leakage between the first baffles 400 or between the second baffles 500 can be avoided.

[0144] In combination Figures 1-2 As shown in the drawings, the air conditioner provided by the embodiments of the present disclosure includes a shell 710, a fan box 720, and the air outlet assembly 10 described above. The shell 710 is configured to have a receiving space, and the shell 710 is provided with a second air outlet. The fan box 720 is arranged in the receiving space, and the fan box 720 is provided with a third air outlet. The fan box 720 and the shell 710 form a sandwiched layer. The air outlet assembly 10 is arranged in the sandwiched layer. The first air outlet of the air outlet assembly 10 corresponds to the third air outlet of the fan box 720, and the air outlet direction of the air outlet assembly 10 is towards the second air outlet.

[0145] The air conditioner includes a shell 710 and a fan box 720. The shell 710 is configured to have a receiving space, and the fan box 720 is arranged in the receiving space. By arranging the fan box 720 independently, the static pressure of the air outlet of the air conditioner can be improved, which is beneficial to improve the air supply amount of the air conditioner and increase the air supply distance of the air conditioner. The shell 710 is provided with a second air outlet, and the fan box 720 is provided with a third air outlet. The second air outlet is also used as the air outlet of the air conditioner as a whole. The first air outlet of the air outlet assembly 10 is connected to the third air outlet of the fan box 720. The air outlet assembly 10 is arranged between the second air outlet and the third air outlet, and is used to guide the air blown out by the third air outlet of the fan box 720 to the second air outlet of the shell 710 at a certain angle. When the plurality of first baffles 400 move to the first position, the second ends of the plurality of first baffles 400 are gathered, so as to realize the far-focusing air supply. When the plurality of first baffles 400 move to the second position, the second ends of the plurality of first baffles 400 are spread, so as to realize the soft air supply in a large range. When the plurality of first baffles 400 are between the first position and the second position, the sharp ends of the plurality of first baffles 400 play a role of disturbing flow, so as to realize the sharp-piercing flow-disturbing air supply. In terms of structure, the fan box 720 and the shell 710 form a sandwiched layer, and the air outlet assembly 10 is arranged in the sandwiched layer. In this way, the movement of the first baffles 400 or the second baffles 500 of the air outlet assembly 10 is neither in the fan box 720 nor outside the shell 710, and the movement of each moving part of the air outlet assembly 10 is not easily interfered.

[0146] The air conditioner provided by the embodiment of the present disclosure has an air outlet assembly 10, which can adjust the air outlet cross section of the air outlet channel formed by the air outlet assembly 10, so that the air supply distance and the air feeling strength of the air conditioner can be changed by adjusting the cross section of the air outlet channel. Specifically, when the rotating speed of the fan is unchanged, the air supply distance is increased and the air feeling is enhanced by reducing the cross section of the air outlet channel, and the air supply distance is reduced and the air feeling is weakened by increasing the cross section of the air outlet channel. The cross section of the air outlet channel can be adjusted to adjust the air supply distance and the air feeling strength without changing the rotating speed of the fan, thereby increasing the means for changing the air outlet form. If the rotating speed of the fan and the cross section of the air channel are adjusted at the same time, a larger range of adjustment of the air supply distance and the air feeling strength can be achieved.

[0147] The air outlet assembly 10 has a moving component to change the air outlet cross section of the air outlet channel. The air outlet assembly 10 is arranged in the interlayer, and the movement of the moving component does not interfere with the components inside the fan box 720, thereby improving the stability of the operation of the air conditioner. The movement of the moving component does not appear outside the shell 710, and the appearance of the air conditioner is more beautiful. The air outlet assembly 10 can be operated by opening the shell 710, thereby facilitating the assembly and maintenance of the air conditioner.

[0148] Optionally, the fan box 720 includes a first box 721, a second box 722, and a fan. The first box 721 has a third air outlet. The second box 722 is in communication with the first box 721, and the second box 722 has an air inlet. The fan is arranged in the second box 722 and is configured to drive air to flow from the air inlet to the third air outlet.

[0149] The first box 721 has the third air outlet, and the second box 722 has the air inlet. The third air outlet is far away from the air inlet, and air outlet short circuit is not easy to occur, which is beneficial to better air circulation. The fan is arranged in the second box 722, and the fan rotates to form an air outlet static pressure to drive air to enter the second box 722 from the air inlet and then blow out through the third air outlet of the first box 721. In the second box 722, there is more turbulence under the stirring of the fan blades. After the air flows from the second box 722 to the first box 721, the first box 721 has a rectifying effect, and the amount of laminar flow in the air increases, so that the air can be blown to a farther distance after blowing out from the third air outlet. By adopting such a setting form, the operating noise of the fan can be reduced, and the air supply distance of the air conditioner can be increased.

[0150] Optionally, the air conditioner further includes a first air outlet duct 711, and the first air outlet duct 711 is arranged at the third air outlet. The bottom plate 11 is arranged at the outer ring of the first air outlet duct 711.

[0151] The bottom plate 11 of the air outlet assembly 10 is fixed to the fan case 720. At the joint position of the bottom plate 11 and the fan case 720, there are some structural protrusions and gaps. The first air outlet cylinder 711 is arranged to smoothly guide the air blown out from the third air outlet into the air outlet air duct of the air outlet assembly 10. In this way, air leakage at the joint position of the air outlet assembly 10 and the fan case 720 is avoided, the kinetic energy loss of the air is reduced, and the air supply effect of the air conditioner is improved.

[0152] Optionally, the air conditioner further comprises a second air outlet cylinder 712, which is arranged at the second air outlet. The plurality of first baffles 400 are located at the outer circle of the second air outlet cylinder 712.

[0153] When the plurality of first baffles 400 move outward to the second position, the second air outlet cylinder 712 is located at the outer circle of the plurality of first baffles 400. The air blown out from the air outlet air duct of the air outlet assembly can be smoothly blown out through the second air outlet under the guidance of the second air outlet cylinder 712. In this way, the air supply effect of the air conditioner is further improved.
