Referring to fig. 1-15, an embodiment of the present disclosure provides an air outlet assembly 10, which includes a fixed ring 100, a plurality of first baffle plates 400, a driving ring 200, and a driving gear 240, wherein the fixed ring 100 has an inner ring defining a first air outlet, and a plurality of first pivot portions 110 are disposed on one surface of the fixed ring 100 at intervals along a circumferential direction; the first baffle plates 400 are rotatably connected to the fixed ring 100 through the first pivot parts 110 in a one-to-one correspondence manner, the axis around which the first baffle plates 400 rotate is parallel to the plane where the first air outlet is located, and the first baffle plates 400 are provided with driving matching parts; the driving ring 200 is coaxial with the fixed ring 100 and can rotate relative to the fixed ring 100, the driving ring 200 is provided with a plurality of first driving parts 210, and when the driving ring 200 rotates, the second ends of the plurality of first baffle plates 400 are driven to move along the direction of being close to or far from the axis of the first air outlet; the outer edge of the driving ring 200 is constructed with gear teeth; the driving gear 240 is meshed with the gear teeth of the driving ring 200, and when the driving gear 240 rotates, the driving ring 200 is driven to rotate.

The disclosed embodiment provides an air outlet assembly 10 including a chassis 11 and a plurality of first baffles 400. The chassis 11 is provided with a first air outlet in the middle, and a plurality of first baffle plates 400 are connected to the chassis 11 and distributed along the circumferential direction of the first air outlet.

Taking one of the first baffle plates 400 as an example, a first end of the first baffle plate 400 is rotatably connected to the chassis 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 can move along the direction approaching to or separating from the axis of the first air outlet.

When the first baffle plates 400 move to the first position in the direction close to the axis of the first air outlet, the second ends of the first baffle plates 400 are gathered into a cone with two open ends. The end with the larger section of the cone is used as the first end, the end with the smaller section is used as the second end, the first end of the cone is in butt joint with the first air outlet formed in the chassis 11, and the second end of the cone is used as the integral air outlet of the air outlet assembly 10. At this time, the air outlet section of the air outlet assembly 10 is reduced, and the air entering the cone is blown to a longer distance under the gathering and guiding action of the plurality of first baffle plates 400, so that the far-focus air supply is realized.

If the cross section of the air outlet is simply reduced, the flow velocity of the air at the air outlet is high, but the air flow is disturbed, more kinetic energy is lost near the air outlet due to molecular collision, and the air supply distance is short. With the air outlet assembly 10 provided in the embodiment of the present disclosure, under the condition that the plurality of first baffle plates 400 gather, each first baffle plate 400 plays a role in guiding air, and air can form a laminar flow under the wall effect of the first baffle plate 400, so that energy loss is small in the movement process, and the air can be blown to a more distant position.

When the first baffle plates 400 move to the second position in the direction away from the axis of the first air outlet, the second ends of the first baffle plates 400 are scattered. 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 chassis 11 is used as the integral air outlet of the air outlet assembly 10, and the air outlet section of the air outlet assembly 10 is larger. The air is directly blown out from the air outlet of the chassis 11 and is not interfered by the plurality of first baffle plates 400, and the air outlet of the air conditioner is large.

It should be noted that, when the plurality of first blocking pieces 400 move between the first position and the second position, the projection of the second ends of the plurality of first blocking pieces 400 on the plane where the air outlets are located is located within the first air outlets. The plurality of first baffles 400 gather but cannot enclose a closed cone. At this time, the first air outlet of the chassis 11 is used as an air outlet of the air outlet assembly 10, and the second ends of the first baffle plates 400 are located on the air outlet path, so as to play a role in turbulence on air. The wind after turbulent flow of the plurality of first baffle plates 400 blows to a relatively short distance and the wind sense is softer, namely, wedge turbulent flow air supply is realized.

The chassis 11 includes a fixing ring 100, and an inner ring of the fixing ring 100 defines a first air outlet. A plurality of first pivoting portions 110 are circumferentially arranged on one surface of the fixed ring 100 at intervals, and the plurality of first baffle plates 400 are rotatably connected to the fixed ring 100 through the plurality of first pivoting portions 110 in a one-to-one correspondence manner; the driving ring 200 is coaxial with the fixing ring 100 and can rotate relative to the fixing ring 100, the driving ring 200 is provided with a plurality of first driving parts 210, the plurality of first baffle plates 400 are provided with first driving matching parts 420, the plurality of first driving parts 210 are matched with the plurality of first driving matching parts 420 in a one-to-one correspondence manner, and when the driving ring 200 rotates, the second ends of the plurality of first baffle plates 400 are driven to move along the direction close to or far away from the axis of the first air outlet.

To achieve the fixing and driving of the plurality of first flaps 400, the chassis 11 includes a fixing ring 100 and a driving ring 200. The fixing ring 100 is used to provide a mounting position for the plurality of first blades 400, that is, the plurality of first blades 400 are rotatably connected to the fixing ring 100. The driving ring 200 is used for driving the plurality of first blocking pieces 400 to synchronously move to a first position or a second position or a position between the first position and the second position.

One surface of the fixed ring 100 is provided with a plurality of first pivoting portions 110, the plurality of first pivoting portions 110 are in one-to-one correspondence with the plurality of first baffle plates 400, and the first baffle plates 400 are rotatably connected to the fixed ring 100 through the first pivoting portions 110. Illustratively, the first pivot portion 110 is a shaft sleeve, and the first end of the first baffle 400 has a rotating shaft 430, and the rotating shaft 430 is matched with the shaft sleeve, so as to implement the rotating connection of the first baffle 400. Still another example, the first pivoting part 110 is a rotation shaft 430, and the first shutter 400 is provided with a shaft sleeve, which is matched with the rotation shaft 430, thereby achieving a rotational connection of the first shutter 400.

The driving ring 200 is disposed parallel to the fixed ring 100, and the driving ring 200 can be rotated in a plane with respect to the fixed ring 100. The driving ring 200 is provided with a plurality of first driving parts 210, each of the first blocking pieces 400 is provided with a first driving engagement part 420, and the plurality of first driving parts 210 are engaged with the plurality of first driving parts 210 in a one-to-one correspondence. When the driving ring 200 rotates, the first driving portion 210 moves circumferentially along the plane of the driving ring 200, so as to drive the first driving engaging portion 420 to move, thereby driving the first blocking piece 400 to rotate around the first pivot portion 110.

The chassis 11 comprises a fixing ring 100, and the fixing ring 100 is used for fixing the plurality of first baffle plates 400, so that the plurality of first baffle plates 400 are convenient to install and position; the driving ring 200 drives the first baffle plates 400 to move simultaneously, and the second ends of the first baffle plates 400 can move to the first position or the second position simultaneously, so that the air outlet assembly 10 is convenient to change the air outlet form; the driving ring 200 is coaxial with the fixed ring 100 and can rotate relative to the fixed ring 100, so that the space required by the movement of the driving ring 200 is small, and the volume of the air outlet assembly 10 is reduced.

By using the air outlet assembly 10 disclosed by the application, the air supply distance and the wind sense can be adjusted by the movement of the plurality of first baffle plates 400, and the air outlet modes are various; the positions of the plurality of first baffle plates 400 can be continuously changed, the air supply distance and the wind sense intensity can be steplessly adjusted, and the personalized requirements of users under different use scenes can be met.

The drive ring 200 has two flat surfaces and one side surface, which is a curved surface. The outer edge of the drive ring 200, i.e. the side of the drive ring 200, is configured with gear teeth. The driving gear 240 is located on the same plane as the driving ring 200, and the driving gear 240 is located outside the driving ring 200.

The drive gear 240 is engaged with the gear teeth of the drive ring 200, and the drive gear 240 serves as a driving gear and the drive ring 200 serves as a driven gear in gear engagement of the drive gear 240 and the drive ring 200. With such arrangement, the outer diameter of the driving ring 200 is larger, and the driving gear 240 can better drive the driving ring 200 to rotate; the driving ring 200 and the driving gear 240 do not overlap in the thickness direction, so that the volume of the air outlet assembly 10 can be reduced.

Optionally, the air outlet assembly 10 further includes a wind shielding barrel 600 disposed on the fixing ring 100, wherein a first end of the wind shielding barrel 600 is abutted with the first air outlet, and the plurality of first blocking pieces 400 are located on an inner ring of the wind shielding barrel 600.

When the plurality of first baffle plates 400 move to the second position, gaps exist between two adjacent first baffle plates 400. Although the plurality of first blocking pieces 400 are located at positions avoiding the first air outlet, the air guiding effect of the first blocking pieces 400 is weakened. Accordingly, a wind shielding cylinder 600 is provided on the chassis 11, and a first end of the wind shielding cylinder 600 is abutted with the first air outlet. The first blocking pieces 400 are positioned at the inner circumference of the wind blocking barrel 600. When the plurality of first baffle plates 400 are gathered into a cone, the wind shielding cylinder 600 does not influence the focusing air supply effect of the plurality of first baffle plates 400; when the first baffle plates 400 move to the second position, the first baffle plates 400 and the air blocking barrel 600 extend along the air outlet direction, and play a role in guiding air. The wind shielding cylinder 600 is provided to jointly play a role of guiding wind with the plurality of first baffle plates 400, so that air leakage between two adjacent first baffle plates 400 of the air outlet assembly 10 is avoided.

Optionally, the length of the wind shielding cylinder 600 is greater than or equal to the length of the first flap 400.

The plurality of first separation blades 400 are used as moving parts, and the outer ring of the wind shielding cylinder 600 positioned on the plurality of first separation blades 400 not only can avoid the interference between the movement of the first separation blades 400 and other parts at the preset installation position, but also can physically protect the plurality of first separation blades 400, so that the plurality of first separation blades 400 are prevented from being damaged in the installation and transportation processes. The length of the air blocking barrel 600 is greater than or equal to that of the first blocking piece 400, and the first blocking piece 400 is completely positioned in the air blocking barrel 600 when rotating to any position, so that the air blocking barrel 600 can better play a role in protection.

Optionally, the inner wall of the wind shielding cylinder 600 is configured with a plurality of embedded grooves, the shape of the embedded grooves is matched with the shape of the first baffle plate 400, and the plurality of second baffle plates 500 are embedded into the plurality of embedded grooves in a one-to-one correspondence when moving to the second position.

When the plurality of first baffle plates 400 rotate to the second position, gaps are reserved among the plurality of first baffle plates 400, and the inner wall is uneven. This results in a loss of kinetic energy of the air, which affects the output of the air outlet assembly 10. The inner wall of the wind blocking barrel 600 is configured with a plurality of embedded grooves, and the plurality of first blocking pieces 400 are embedded into the plurality of embedded grooves in a one-to-one correspondence when moving to the first position. The inner walls of the wind blocking barrel 600 and the first blocking pieces 400 are flat during common wind guiding, so that the wind outlet effect of the wind outlet assembly 10 can be improved.

Optionally, the inner wall of the wind shield 600 is configured with a plurality of deflector ribs.

When the plurality of first baffle plates 400 and the air blocking barrel 600 guide air jointly, two adjacent guide ribs form an air guide groove, and air is divided into a plurality of strands to flow along the plurality of air guide grooves. Under the guiding action of the plurality of air guide grooves, even if a certain vortex exists in the air, the air moves along the air outlet direction as a whole. This reduces the kinetic energy loss of the air flowing through the air outlet assembly 10, thereby increasing the air supply distance of the air outlet assembly 10.

Optionally, the air outlet assembly 10 further includes a mounting ring 300, which is coaxial with the fixing ring 100, and the mounting ring 300 is disposed opposite to the fixing ring 100 to form a driving space, and the driving ring 200 is rotatably disposed in the driving space.

The mounting ring 300 is used to fix the air outlet assembly 10 at a predetermined mounting position, such as an air outlet of a cabinet air conditioner. The chassis 11 is sequentially provided with a mounting ring 300, a driving ring 200 and a fixing ring 100 along the air outlet direction, and the driving ring 200 is positioned between the mounting ring 300 and the fixing ring 100. When the driving ring 200 drives the first blocking pieces 400 to rotate, the movement of the driving ring 200 is not easy to interfere with other parts of the air outlet assembly 10 or the air conditioner. The mounting ring 300 forms a driving space with the fixing ring 100, and thus the air outlet assembly 10 may have a neat appearance.

Alternatively, the mounting ring 300 is provided with a first fastening portion 310 extending along a radial direction, the fixing ring 100 is provided with a second fastening portion 150 extending along a radial direction, the first fastening portion 310 and the second fastening portion 150 are fastened to form a gear installation space, and the driving gear 240 is rotatably disposed in the gear installation space.

To achieve the mounting and positioning of the driving gear 240, the mounting ring 300 is provided with a first fastening portion 310 extending in a radial direction, and the fixing ring 100 is provided with a second fastening portion 150 extending in a radial direction. The first fastening portion 310 and the second fastening portion 150 define a gear installation space. One side of the gear installation space facing the driving ring 200 is provided with a relief gap to allow the driving gear 240 to be engaged with the driving ring 200. With such an arrangement, the fixing of the drive gear 240 is facilitated. In addition, the first fastening portion 310 corresponds to the second fastening portion 150, and can be used as a visual identification mark when the mounting ring 300 is connected to the fixing ring 100, so that the assembly of the air outlet assembly 10 is facilitated.

Optionally, an outward surface of the first buckling part 310 is configured with a containing groove; the air outlet assembly 10 further comprises a driving motor embedded in the accommodating groove.

The air outlet assembly 10 is also provided with a drive motor for powering the rotation of the drive ring 200. Specifically, the first fastening portion is configured with a receiving groove outside, the driving motor is embedded in the receiving groove, and the output shaft penetrates the first fastening portion 310 to be connected to the driving gear 240. With such arrangement, the driving motor is located on the side of the fixing ring 100 where the first blocking piece 400 is located, and the side of the mounting ring 300 away from the first blocking piece 400 is relatively flush. This allows for a more compact construction of the drive assembly.

Optionally, a plurality of positioning bosses 330 are disposed on a surface of the mounting ring 300 facing the fixing ring 100 along the circumferential direction of the first air outlet, the fixing 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 overlapped on top of the positioning bosses 330 in a one-to-one correspondence.

The driving ring 200 rotates between the mounting ring 300 and the fixing ring 100, and a margin is required between the mounting ring 300 and the fixing ring 100 for the rotation of the driving ring 200. Accordingly, the mounting ring 300 is provided with a plurality of positioning bosses 330 at intervals along the circumferential direction thereof, and the fixing ring 100 is provided with a plurality of positioning engaging portions 170 along the circumferential direction thereof. One surface of the positioning boss 330 facing the fixing ring 100 abuts against one surface of the positioning engaging portion 170 facing the mounting ring 300. With such an arrangement, mounting positioning of the mounting ring 300 in terms of relative distance and coaxiality with respect to the fixing ring 100 is facilitated.

Alternatively, the first fastening portion 310 is integrally formed with one of the positioning bosses 330, and the second fastening portion 150 is integrally formed with one of the positioning engaging portions 170.

With such an arrangement, injection molding of the securing ring 100 and the mounting ring 300 is facilitated. In addition, the positioning engaging portion 170 and the positioning boss 330 serve as reinforcing ribs, so that the structural strength of the first fastening portion 150 and the second fastening portion 150 can be improved.

When the driving ring 200 drives the first baffle 400 to move between the first position and the second position, the rotation angle of the driving ring 200 is fixed, and the outer edge of the driving ring 200 has a partially toothed structure. With this arrangement, the difficulty in machining the drive ring 200 can be reduced. In addition, the driving ring 200 is partially toothed, and the driving ring 200 is not driven to rotate beyond its rotation range even if the rotation of the driving motor is abnormal, thereby preventing the first blocking piece 400 from rotating beyond its rotation range. This may also improve the safety of the air outlet assembly 10.

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 with the first blocking piece 400 relative to the first guide groove 211 under the restriction of the first pivoting portion 110. When the driving ring 200 rotates in the first direction, the first end of the first guide groove 211 is engaged with the first driving pin 421, and the second end of the first guide groove 211 is engaged with the first driving pin 421. The distance from the first driving pin 421 to the axis of the air outlet is gradually increased under the limiting action of the first guide groove 211. The first blocking piece 400 takes the rotation shaft as a 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 is gradually increased, the distance between the second end of the first blocking piece 400 and the axis of the air outlet is gradually decreased. The first baffle plates 400 all do the same motion, and the second ends of the first baffle plates 400 gather inwards to realize the far focus air-out aggregation. When the driving ring 200 rotates in the second direction, the distance between the first driving pin 421 and the axis of the air outlet is gradually reduced, and the second ends of the plurality of first blocking pieces 400 are scattered to realize the air outlet without wind sensation.

When the first blocking piece 400 rotates, the first driving pin 421 also rotates, and the first driving pin 421 penetrates through the avoidance groove formed in the fixing ring 100 so as to extend into the first guide groove 211 of the driving ring 200. With such an arrangement, the first driving pin 421 can be engaged with the first guide groove 211 of the driving ring 200 without exceeding the driving ring 200, simplifying the structure of the air outlet assembly 10.

Optionally, the length direction of the first avoidance groove 141 is along the radial direction of the fixing ring 100, and the width is adapted to the size of the first driving pin 421.

The first driving pin 421 moves along the radial direction of the fixing ring 100 when rotating, and the length direction of the first escape groove 141 is along the radial direction of the fixing ring 100, so that a rotating space can be reserved for the rotation of the first driving pin 421. The width of the first avoiding groove 141 is adapted to the size of the first driving pin 421, so that the movement of the first driving pin 421 can be limited to be performed in the radial direction of the mounting ring 300, and the friction force between the first guiding groove 211 and the first driving pin 421 can be prevented from driving the first driving pin 421 to rotate along the circumferential direction of the fixing ring 100 when the driving ring 200 rotates. This may improve the reliability of operation of the air outlet assembly 10.

The plurality of first pivoting portions 110 are used to connect the plurality of first flaps 400, and the plurality of second pivoting portions 130 are used to connect the plurality of second flaps 500. The first blocking pieces 400 and the second blocking pieces 500 are connected to the fixing ring 100, so that the structure of the air outlet assembly 10 can be simplified, and the volume of the air outlet assembly 10 can be reduced.

Optionally, the driving ring 200 is provided with a plurality of second guide grooves 221, the first end of the second baffle 500 is provided with a second driving pin 521, the second driving pin 521 extends into the second guide groove 221, and the driving ring 200 drives the second baffle 500 to rotate bidirectionally when rotating bidirectionally.

The first guide groove 211 is used for driving the first baffle 400 to rotate, and the second guide groove 221 is used for driving the second baffle 500 to rotate. The engagement of the second driving pin 521 with the second guide groove 221 may be referred to as the engagement of the first driving pin 421 with the first guide groove 211. With such an arrangement, the driving ring 200 simultaneously drives the plurality of first barrier pieces 400 and the plurality of second barrier pieces 500 to rotate when rotating, thereby improving the integration degree of the air outlet assembly 10.

Optionally, the fixing ring 100 is provided with a plurality of second avoidance grooves 142, the plurality of second avoidance grooves 142 are located on the outer ring of the plurality of first avoidance grooves 141, and the second driving pins 521 extend into the second guide grooves 221 through the second avoidance grooves 142.

When the second blocking piece 500 rotates, the second driving pin 521 also rotates, and the second driving pin 521 penetrates the second escape groove 142 formed in the fixing ring 100 to extend into the second guide groove 221 of the driving ring 200. With such an arrangement, the second driving pins 521 can be engaged with the second guide grooves 221 of the driving ring 200 without exceeding the driving ring 200, simplifying the structure of the air outlet assembly 10.

Optionally, the mounting ring 300 is provided with a plurality of third avoiding grooves 341 corresponding to the plurality of first avoiding grooves 141, and the first driving pin 421 passes through the first guiding groove 211 and extends into the third avoiding grooves 341.

The third avoidance groove 341 cooperates with the first avoidance groove 141 to limit the movement of the first driving pin 421 along the circumferential direction of the fixing ring 100. In this way, the rotation of the first driving pin 421 can be better limited to its preset rotation plane, and local overstressed deformation or breakage of the first driving pin 421 can be avoided.

Optionally, the mounting ring 300 is provided with a plurality of fourth avoidance grooves 342 corresponding to the plurality of second avoidance grooves 142, and the second driving pins 521 extend into the fourth avoidance grooves 342 through the second guide grooves 221.

The fourth avoidance groove 342 cooperates with the second avoidance groove 142 to limit the movement of the second driving pin 521 along the circumferential direction of the fixing ring 100. This can better limit the rotation of the second driving pin 521 to its preset rotation plane and can avoid local overstressed deformation or breakage of the second driving pin 521.

Thus, the third escape groove 341 of the mounting ring 300 and the first escape groove 141 of the fixing ring 100 together restrict the movement of the first driving pin 421 to the radial direction of the fixing ring 100. With this arrangement, the first driving pin 421 can be further prevented from moving in the circumferential direction of the fixing ring 100. Optionally, the first guide groove 211 gradually increases from the first end to the second end and the included angle between the axis of the first air outlet.

With the axial direction of the first air outlet being the thickness direction of the first guide groove 211, the first guide groove 211 has two opposite inner edges, 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 and the axis of the first air outlet along the axial direction of the first air outlet. If the two are parallel, the first driving pin 421 may interfere with the inner edge of the first guide groove 211 when rotating. If a large fit margin is provided between the first guide groove 211 and the first driving pin 421, there is a possibility that the position of the first driving pin 421 is unclear when the driving ring 200 rotates. Specifically, the first blocking piece 400 blocks more air outlets when located at the first position, and the first driving pin 421 is inclined more. When the first baffle 400 is located at the second position, the length direction of the first baffle is along the axis of the first air outlet, and at this time, the first driving pin 421 is inclined less to be substantially parallel to the axis of the first air outlet. The included angle between the first guide slot 211 and the air outlet from the first end to the second end gradually increases, and the inclination degree of the first driving pin 421 in the rotation process of the first baffle 400 is matched with the inclination degree of the first guide slot 211. This reduces friction between the first guide groove 211 and the first driving pin 421 on the one hand, and makes it possible to rotate the first driving pin 421 to a predetermined angle better on the other hand.

Specifically, the first baffle 400 includes a plate body 410, the plate body 410 serves as a main body of the first baffle 400, and the plate body 410 plays roles of enclosing and guiding air when the plurality of first baffles 400 are combined. The width of the plate 410 gradually decreases from the first end to the second end to enable the plates to be spliced into a sealed cone when gathered. The rotation shaft is disposed at the first end of the plate 410, and the rotation shaft cooperates with the first pivot portion 110 of the fixing ring 100 to rotatably connect the first blocking piece 400 to the fixing ring 100. The first driving pin 421 serves as a first driving engagement portion 420, one end of which is connected to the first end or the rotation shaft of the plate body 410, and the other end of which extends into the first guide groove 211. With this arrangement, the driving ring 200 is facilitated to drive the first barrier 400 to rotate.

Alternatively, the plate body 410 includes a wind shielding part 411 and a mounting part 412, wherein the wind shielding part 411 gradually decreases in width from the first end to the second end; the installation part 412 is connected to the first end of the baffle, and a first included angle is formed between the installation part 412 and the wind shielding part 411.

The width of the wind shielding portion 411 gradually decreases from the first end to the second end, which is advantageous for the wind shielding portions 411 of the plurality of first blades 400 to be combined.

In the case that the plurality of first blocking pieces 400 are enclosed to form a cone, the wind shielding portion 411 is substantially along the axial direction of the first air outlet in the length direction, and the mounting portion 412 is substantially along the radial direction of the first air outlet. The mounting portion 412 and the wind shielding portion 411 have a first angle therebetween, so that the mounting portion 412 can be attached to the chassis 11. The mounting part 412 is attached to the chassis 11, and the first baffle 400 can be fixed without opening holes in the chassis 11, so that air leakage of the air outlet assembly 10 can be avoided; the mounting portion 412 is attached to the chassis 11, and the contact area between the mounting portion and the chassis 11 is large, so that the fixing effect of the chassis 11 to the first baffle 400 can be improved.

In the case where the first angle is equal to 90 degrees, the length direction of the mounting portion 412 is along the radial direction of the first air outlet and the length direction of the wind shielding portion 411 is along the axial direction of the first air outlet. The first included angle is greater than 90 degrees, and the second ends of the wind shielding portions 411 are gathered inward under the condition that the mounting portions 412 are attached to the chassis 11, so that the plurality of first blocking pieces 400 are spliced into a cone. With such an arrangement, the fixing effect of the chassis 11 to the first chassis 11 can be further improved.

Alternatively, the middle portion of the wind shielding part 411 protrudes toward the first air outlet.

The middle portion of the wind shielding part 411 protrudes toward the first air outlet, that is, the angle between the axis of the cone and the first air outlet from the first end to the second end is gradually reduced. In the cone, the increase in air flow rate is more in the portion near the first end and better in the portion near the second end. The air is throttled and accelerated to form more turbulent flow at the front section of the cone, the speed change is less at the rear section of the cone, and the air is rectified under the wall effect at the rear end of the cone to reduce turbulent flow and increase laminar flow. The air may blow to a greater distance after being blown out of the first cone. With such a configuration, the air supply distance of the air outlet assembly 10 can be further increased.

Optionally, an inward surface of the plate body 410 is configured with an air guiding protrusion 413, and the air guiding protrusion 413 extends along a length direction of the first baffle 400.

The air guide protrusions 413 of the inner surface of the plate body 410 have a wedge shape or a triangle shape, and the width thereof gradually decreases from the first end to the second end of the plate body 410. When the plurality of first baffle plates 400 are assembled, two adjacent wind guide protrusions 413 form a wind guide groove. The air flowing in the cone is divided into a plurality of strands by the air guiding protrusions 413 to flow along the plurality of air guiding grooves. Under the guiding action of the plurality of first air guide grooves, even if a certain vortex exists in the air, the air moves along the air outlet direction as a whole. In this way, the influence of the air close to the inner wall of the cone on the air flow of other parts can be reduced, and the kinetic energy loss of the air in the cone can be reduced, so that the air supply distance of the air outlet assembly 10 is increased.

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

The plate body 410 is configured with two wind guiding protrusions 413, and more wind guiding grooves can be formed on the inner wall of the cone. This may further reduce the kinetic energy loss of the air within the cone and thereby increase the distance of the air from the air outlet assembly 10.

Alternatively, two wind guiding protrusions 413 are respectively close to two sides of the plate body 410, one side of the wind guiding protrusion 413 is used as the first splicing part 414, and when the plurality of first baffle plates 400 are spliced, the wind guiding protrusions 413 of two adjacent first baffle plates 400 are spliced.

The two wind guide protrusions 413 of the plate body 410 are adjacent to the two sides, and the wind guide protrusions 413 simultaneously serve as structural reinforcement members of the first plate body 410. When the plurality of first baffle plates 400 are assembled, the first baffle plates 400 are not easy to deform; the first baffle 400 is not easily vibrated when air flows through the cone.

The air guide protrusions 413 are adjacent to both sides of the plate body 410, and preferably the air guide protrusions 413 are flush with the sides of the plate body 410. The plate body 410 is thus thicker at the sides. When the thickened side edges are used as the first splicing parts 414 and a plurality of first baffle plates 400 are spliced, the first baffle plates 400 are not easy to deform due to mutual contact in the first aspect; in the second aspect, the two adjacent first baffle plates 400 with thicker side edges of the plate body 410 are not easy to be misplaced or flash-stitched when spliced.

Optionally, the outward facing side of the plate body 410 is configured with wedge-shaped protrusions 440.

Alternatively, the width of the wedge-shaped protrusion 440 gradually increases from the first end to the second end of the plate 410, and the width of the air guiding groove gradually increases from the first end to the second end of the plate 410, and the wedge-shaped protrusion 440 corresponds to the air guiding groove.

The width of the wind guiding groove gradually increases from the first end to the second end, and the width of the two wind guiding protrusions 413 adjacent to the wind guiding groove gradually decreases from the first end to the second end of the plate body 410. The width of the air guide groove is gradually increased, and the air guide section of the air guide groove is gradually expanded when air flows in the air guide groove. Therefore, the vortex formed by the contact of the air in the air guide groove and the wall surface of the air guide groove can be generated in the air guide groove as much as possible, and the kinetic energy loss generated by the contact of the vortex and the air in other positions is reduced. The wedge-shaped protrusions 440 correspond to the wind guide grooves such that the thickness thereof is uniform throughout the entire plane of the plate body 410. With such arrangement, the structural strength of the first baffle 400 is improved, and the weight of the first baffle 400 is reduced, thereby reducing the cost of the air outlet assembly 10.

Alternatively, the rotation shaft is provided at an end of the mounting portion 412 remote from the wind shielding portion 411.

The rotation shaft is disposed at one end of the mounting portion 412 away from the wind shielding portion 411, and when the first baffle 400 rotates, the mounting portion 412 and the wind shielding portion 411 rotate on one side of the rotation shaft 430, so that the first baffle 400 is not easy to interfere with the chassis 11 when rotating.

Optionally, the fixing ring 100 is provided with a plurality of first connecting pieces 120 along the circumferential direction of the first air outlet, two ends of each first connecting piece 120 are provided with shaft holes, the axis of each shaft hole and the plane of the first air outlet are located, each two adjacent first connecting pieces 120 serve as a first pivoting portion 110, and two ends of the rotating shaft of the first baffle 400 are respectively inserted into two opposite shaft holes of the two adjacent first connecting pieces 120.

Optionally, the shaft hole is radially provided with a clamping gap, and the rotating shaft of the first baffle 400 is clamped into the shaft hole along the clamping gap.

If the two ends of the rotating shaft are respectively arranged in the shaft holes along the axial direction of the rotating shaft, the rotating shaft can be elastically deformed to a certain extent in the assembling process, or the shaft holes need to be provided with assembling allowance for the rotating shaft. In this case, the first shutter 400 may be shifted in the axial direction of the rotation shaft when rotated. The shaft hole is radially provided with a clamping gap, and the width of the clamping gap is smaller than the diameter of the rotating shaft. When the first baffle 400 is assembled, the rotating shaft is clamped into the shaft hole from the clamping notch along the radial direction and then is in clearance fit with the shaft hole so as to realize rotatable connection of the first baffle 400. With such a configuration, the assembly of the first blocking piece 400 can be facilitated and the mounting accuracy of the first blocking piece 400 can be improved.

Optionally, the first connecting member 120 is provided with a first shaft hole and a second shaft hole, and a second included angle is formed between the first shaft hole and the second shaft hole.

The plurality of first baffle plates 400 can be gathered together and enclosed into a cone, and the rotating shafts of the plurality of first baffle plates 400 are enclosed into a regular polygon, so that the shape with larger area can be enclosed by less materials. The rotation axis of the first baffle 400 is one side of a regular polygon, and a certain included angle a is formed between two adjacent rotation axes. In the case where the number of first barrier ribs 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, so that the rotating shafts of the first baffle plates 400 can be better restrained, and the plurality of first baffle plates 400 enclose a cone with a larger wind guide section at the bottom end.

Optionally, the first shaft hole and the second shaft hole are communicated.

This may reduce the difficulty of injection molding of the first connector 120 and reduce the amount of injection molding material for the first connector 120, thereby reducing the cost of the air outlet assembly 10.

Alternatively, the two side ends of the first baffle plates 400 are provided with first splicing parts 414, and each two adjacent first baffle plates 400 can be spliced by the two first splicing parts 414.

When the plurality of first baffle plates 400 move inwards to the first position, the plurality of first baffle plates 400 are spliced into a cone. If a gap exists between two adjacent first baffle plates 400, the air supply effect of the air outlet assembly 10 is affected due to the air leakage of the gap. Two ends of each first baffle 400 are provided with first splicing parts 414, and two adjacent first baffle 400 are spliced through the first splicing parts 414. This improves the air-blowing effect of the air-out assembly 10 and reduces noise generated when air flows through the gap between the adjacent two first blades 400.

Optionally, the first splicing portion 414 is made of an elastic material.

The first spliced portion 414 between two adjacent first baffle plates 400 is elastically deformed when the plurality of first baffle plates 400 are moved inward to the first position. This can further prevent the air leakage of the cone when the plurality of first blocking pieces 400 are gathered.

Optionally, the air outlet assembly 10 further includes a plurality of second blocking pieces 500 disposed along a circumferential direction of the first air outlet and located on an outer ring of the plurality of first blocking pieces 400, wherein a first end of each second blocking piece 500 is rotatably connected to the chassis 11 so that a second end can move along a direction close to or far away from an axis of the first air outlet, the plurality of second blocking pieces 500 gather inwards when the second end of the plurality of first blocking pieces 400 moves inwards to the first position, and each second blocking piece 500 is located between two adjacent first blocking pieces 400 when the second end of the plurality of first blocking pieces 400 moves outwards to the second position.

The plurality of first baffle plates 400 are separated from the first position, and a larger gap is generated between two adjacent first baffle plates 400. The air outlet assembly 10 is provided with two circles of blocking sheets, namely a plurality of first blocking sheets 400 of an inner ring and a plurality of second blocking sheets 500 of an outer ring. The second blocking pieces 500 are also distributed along the circumferential direction of the first air outlet, and each second blocking piece 500 is rotatably connected to the chassis 11, and the second end of each second blocking piece 500 can move along the direction of the axis near or far from the air outlet.

The plurality of first blocking pieces 400 form a first cone when moving inwards to the first position, and the plurality of second blocking pieces 500 form a second cone when moving inwards to the first position, and the second cone is positioned on the outer ring of the first cone. At this time, each second barrier 500 shields the splice seam between two adjacent first barriers 400. With such a configuration, air leakage from the splice position of two adjacent first barrier sheets 400 can be further avoided.

The plurality of first baffle plates 400 are enclosed into a cylinder when moving outwards to the second position, and gaps are reserved between two adjacent first baffle plates 400. The plurality of second blocking pieces 500 are enclosed into a cylinder when moving outwards to the second position, and each second blocking piece 500 is used for shielding a gap between two adjacent first blocking pieces 400. Thus, the first baffle 400 and the second baffle 500 enclose a closed air duct. This may improve the wind guiding effect of the wind outlet assembly 10 when the plurality of first blocking plates 400 are located at the second position.

When the plurality of first baffle plates 400 are located between the first position and the second position, the projection of the second end of the first baffle plates 400 on the plane where the first air outlet is located in the first air outlet, and the second end of the first baffle plates 400 plays a role in turbulence. At this time, the projection of the second end of the second baffle 500 on the plane where the first air outlet is located is also located in the first air outlet, and the second end of the second baffle 500 also plays a role in turbulence. This can further enhance the wedge turbulence air supply effect of the air outlet assembly 10.

Alternatively, the plurality of first and second shutters 400 and 500 each rotate inward when the driving ring 200 rotates in the first direction, and the movement of the plurality of first shutters 400 leads the rotation of the plurality of second shutters 500, and the plurality of first and second shutters 400 and 500 each rotate outward when the driving ring 200 rotates in the second direction, and the rotation of the plurality of second shutters 500 leads the rotation of the plurality of first shutters 400.

When the driving ring 200 rotates in the first direction, the plurality of first and second shutters 400 and 500 each rotate inward, and the movement of the plurality of first shutters 400 leads the rotation of the plurality of second shutters 500. That is, when the plurality of first flaps 400 and the plurality of second flaps 500 move inward, the plurality of first flaps 400 move first and the plurality of second flaps 500 move later. This forms a wind-spreading interlayer between the first barrier 400 of the inner race and the first barrier 400 of the outer race. Part of air entering the air outlet assembly 10 from the first air outlet firstly enters the air dispersing interlayer between the first baffle plate 400 and the second baffle plate 500 through the air guiding gap formed between the two adjacent first baffle plates 400, and then is blown out through the air guiding gap formed between the two adjacent second baffle plates 500. The turbulent flow between the plurality of first baffle plates 400 and the plurality of second baffle plates 500 is provided with a wind-dispersing interlayer as a buffer, and air is uniformly mixed in the wind-dispersing interlayer after being disturbed by the first baffle plates 400 and then blown out after being disturbed by the second baffle plates 500. By adopting the arrangement mode, the air dispersing interlayer can be formed, so that the plurality of first baffle plates 400 and the plurality of second baffle plates 500 can be matched better to realize the wedge turbulence function.

Similarly, when the driving ring 200 rotates in the second direction, the plurality of first tabs 400 and the plurality of second tabs 500 are rotated outwardly, and the rotation of the plurality of second tabs 500 leads the rotation of the plurality of first tabs 400. When the plurality of first flaps 400 and the plurality of second flaps 500 are rotated outward, the plurality of second flaps 500 move first and the plurality of first and second flaps move second. In this way, a wind dispersing interlayer is formed between the first baffle 400 of the inner ring and the second baffle 500 of the outer ring, so that the plurality of first baffle 400 and the plurality of second baffle 500 can be matched better to realize the wedge turbulence function.

By adopting the arrangement mode, a certain time difference exists between the movements of the first baffle plates 400 and the second baffle plates 500, and a wind dispersing interlayer can be formed between the first baffle plates 400 and the second baffle plates 500, so that the first baffle plates 400 and the second baffle plates 500 can be matched better to realize the wedge turbulence function.

Optionally, an outward side of the first baffle 400 is configured with a wedge-shaped protrusion 440, and the wedge-shaped protrusion 440 is embedded between two adjacent second baffles 500 when the first baffle 400 and the second baffle 500 are both rotated to the second position.

When the first baffle plates 400 and the second baffle plates 500 are moved to the second position, the air outlet is opened with the maximum opening, and the first baffle plates 400 and the second baffle plates 500 are enclosed to form a cylinder. The outward surface of the first baffle 400 is configured with a wedge-shaped protrusion 440, and two sides of the wedge-shaped protrusion 440 are respectively abutted with two adjacent second baffles 500. In this way, the wedge-shaped protrusions 440 can position the two second barrier pieces 500 connected. The first blocking piece 400 of the inner ring and the second blocking piece 500 of the outer ring are locked by the wedge-shaped protrusions 440, so that the first blocking piece 400 or the second blocking piece 500 can be prevented from shaking.

Alternatively, in the case that the chassis 11 includes the fixed ring 100 and the driving ring 200, one surface of the fixed ring 100 is provided with a plurality of second pivoting parts 130 at intervals in the circumferential direction, the plurality of second pivoting parts 130 are located at outer rings of the plurality of first pivoting parts 110, and the plurality of second blocking pieces 500 are rotatably connected to the fixed ring 100 through the plurality of second pivoting parts 130 in one-to-one correspondence; the driving ring 200 is further provided with a plurality of second driving portions 220, the plurality of second blocking pieces 500 are respectively provided with a second driving matching portion 520, the plurality of second driving portions 220 are matched with the plurality of second driving matching portions 520 in a one-to-one correspondence manner, and the plurality of second blocking pieces 500 are driven to rotate when the driving ring 200 rotates.

One surface of the fixed ring 100 is provided with a plurality of first pivoting portions 110 and a plurality of second pivoting portions 130, and the plurality of second pivoting portions 130 are located at outer rings of the plurality of first pivoting portions 110. The first plurality of pivoting portions 110 are used to rotatably connect the first plurality of flaps 400 to the stationary ring 100, and the second plurality of pivoting portions 130 are used to rotatably connect the second plurality of flaps 500 to the stationary ring 100. Thus, the installation and positioning of the plurality of first blocking pieces 400 and the plurality of second blocking pieces 500 can be realized by one fixing ring 100, and the structure of the air outlet assembly 10 is simplified.

The driving ring 200 is provided with a plurality of second driving portions 220, each second blocking piece 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 are in one-to-one correspondence, and the driving ring 200 simultaneously drives the plurality of first blocking pieces 400 and the plurality of second blocking pieces 500 to rotate when rotating. With such arrangement, the plurality of first blocking pieces 400 and the plurality of second blocking pieces 500 can be simultaneously driven to rotate by one driving ring 200, which is beneficial to synchronous movement of the plurality of first blocking pieces 400 and the plurality of second blocking pieces 500, and simplifies the structure of the air outlet assembly 10.

Optionally, the mounting ring 300 is configured with a first runner 320; the fixed ring 100 is provided with a second chute 160 corresponding to the first chute 320; the driving ring 200 is provided with sliding posts 230, and both ends of the sliding posts 230 respectively extend beyond both sides of the driving ring 200 and respectively extend into the first sliding groove 320 and the second sliding groove 160.

The driving ring 200 rotates in the driving space, and if there is surface friction between the driving ring 200 and the mounting ring 300 or the fixing ring 100, the rotation of the driving ring 200 is affected by a large friction force. The mounting ring 300 is configured with a first sliding groove 320, and the fixing ring 100 is configured with a second sliding groove 160 corresponding to the first sliding groove 320. The first chute 320 and the second chute 160 are both arc-shaped chutes. The driving ring 200 is further provided with sliding posts 230, and both ends of the sliding posts 230 respectively extend beyond both sides of the driving ring 200 and respectively extend into the first sliding groove 320 and the second sliding groove 160. Thus, on the one hand, the form of the cooperation of the sliding post 230 and the sliding groove defines a sliding track for the driving ring 200, which facilitates the rotation of the driving ring 200; on the other hand, the form in which the sliding posts 230 are engaged with the sliding grooves reduces the rotational friction of the driving ring 200, and the driving ring 200 can be rotated more smoothly. In addition, both ends of the sliding post 230 extend into the first sliding groove 320 and the second sliding groove 160, respectively, so that the driving ring 200 is advantageously kept at a relative distance from the mounting ring 300 and the fixing ring 100. With such arrangement, concentricity and flatness of the driving ring 200 during rotation can be improved, which is advantageous for the driving ring 200 to drive the plurality of first blocking pieces 400 to rotate synchronously.

Optionally, when the sliding column 230 is located at the first end of the first chute 320, the second ends of the plurality of first blocking pieces 400 rotate inwards to the first position and gather into a cone with two open ends, and at this time, the first air outlet is opened with a minimum opening; when the sliding column 230 is located at the second end of the first chute 320, the second ends of the plurality of first blocking pieces 400 rotate outwards to the second position so that the first air outlet is opened with the maximum opening.

After the plurality of first blocking pieces 400 rotate inwards to the first position, if the driving ring 200 continues to rotate, the first blocking pieces 400 may deform or flash, which affects the air outlet effect of the air outlet assembly 10. Therefore, the movement of the first shutter 400 needs to be limited. Since the rotation of the first blocking piece 400 is driven by the rotation of the driving ring 200, the rotation limiting of the driving ring 200 also realizes the rotation limiting of the first blocking piece 400. Specifically, the first shutter 400 rotates between a first position and a second position, and accordingly, the sliding column 230 slides between a first end and a second end of the first sliding chute 320. That is, both ends of the first sliding chute 320 serve as sliding limiting portions of the sliding column 230. With such an arrangement, the first baffle 400 can be accurately moved to the first position or the second position, thereby improving accuracy of motion control of the air outlet assembly 10 on the first baffle 400.

Optionally, when the sliding column 230 is located at the first end of the second chute 160, the second ends of the plurality of first blocking pieces 400 rotate inwards to the first position and gather into a cone with two open ends, and at this time, the first air outlet is opened with a minimum opening; when the sliding column 230 is located at the second end of the second chute 160, the second ends of the plurality of first blocking pieces 400 rotate outwards to the second position so that the first air outlet is opened with the maximum opening.

The same effect can be achieved by limiting the rotation of the driving ring 200 through the second sliding groove 160 and the rotation of the driving ring 200 through the first sliding groove 320.

Alternatively, the outer ring of the fixing ring 100 is protruded to form an annular step 180, the plurality of second pivoting parts 130 are disposed above the annular step 180, and the plurality of first pivoting parts 110 are disposed at the inner ring of the fixing ring 100.

The outer ring of the fixing ring 100 is used for connecting the plurality of second blocking pieces 500, and the inner ring is used for connecting the plurality of first blocking pieces 400. When the plurality of first blocking pieces 400 are spliced, a gap is easily generated at a position close to the fixing ring 100, and the gap includes a gap between two adjacent first blocking pieces 400 and a gap between the first blocking piece 400 and the fixing ring 100. Therefore, the fixing ring 100 is provided with an annular step 180, and the outer ring of the fixing ring 100 is higher than the inner ring of the fixing ring 100, that is, the plurality of first connection members 120 are disposed below the step, and the plurality of second connection members are disposed above the step. The slits of the plurality of first blocking pieces 400 at positions near the fixing ring 100 are blocked by the side walls of the annular step 180. With such a configuration, the sealing performance of the first blocking plates 400 can be improved when they are combined, thereby improving the air outlet effect of the air outlet assembly 10. Further, the pivoting position of the first shutter 400 is below the step and the pivoting position of the second shutter 500 is above the step, and rotational interference is not easily generated even if the distance therebetween is close. Providing the annular step 180 may reduce the distance between the first barrier 400 and the second barrier 500, thereby improving the tightness of the air outlet assembly 10.

The housing 710 has a second air outlet, and the fan case 720 has a third air outlet. The second air outlet is also used as the integral air outlet of the air conditioner. The first air outlet of the air outlet assembly 10 is in butt joint with the third air outlet of the fan box 720, and the air outlet assembly 10 is arranged between the second air outlet and the third air outlet and is used for guiding the air blown out by the third air outlet of the fan box 720 to the second air outlet of the shell 710 according to a certain angle. When the first baffle plates 400 move to the first position, the second ends of the first baffle plates 400 gather, so that far-focus air supply is polymerized; when the first baffle plates 400 move to the second position, the second ends of the first baffle plates 400 are scattered, so that soft air outlet in a large range is realized; when the plurality of first baffle plates 400 are between the first position and the second position, the tips of the plurality of first baffle plates 400 play a role in turbulence, so that wedge turbulence air supply is realized. Structurally, the fan case 720 and the housing 710 form a sandwich, and the air outlet assembly 10 is disposed in the sandwich.

By using the air conditioner provided by the embodiment of the disclosure, the air outlet section of the air outlet channel constructed by the air outlet component 10 is adjustable, so that the air supply distance and the wind sense of the air conditioner can be changed by adjusting the section of the air outlet channel. Specifically, under the condition that the rotating speed of the fan is unchanged, the section of the air outlet duct is reduced, and the air supply distance is increased, so that the wind sensation is enhanced; and when the section of the air outlet duct is increased, the air supply distance is reduced, and the wind sense is weakened. The section of the air outlet duct is adjustable, the air supply distance and the wind sense intensity can be adjusted under the condition of not changing the rotating speed of the fan, and a means for changing the air outlet form is added. If the rotating speed of the fan and the section of the air duct are adjusted at the same time, the air outlet distance and the wind sense can be adjusted in a larger range.

The first box 721 is provided with the third air outlet, and the second box 722 is provided with the air inlet. The third air outlet is far away from the air inlet, so that the air outlet is not easy to be short-circuited, and better circulation of air is facilitated. The fan is arranged in the second box 722, and when the fan rotates, air is formed to be driven by static pressure of air outlet air, enters the second box 722 from the air inlet and is blown out through the third air blowing opening of the first box 721. In the second housing 722, there is more turbulence under agitation by the fan blades. After the air flows through the first box 721 from the second box 722, the first box 721 has a rectifying effect, the laminar flow in the air increases, and the air can be blown to a longer distance after being blown out from the third air outlet. With such arrangement, the fan operation noise can be reduced and the air supply distance of the air conditioner can be increased.
