[0043] 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.

[0044] When the air conditioner operates in a cooling or heating mode, the air outlet of the indoor unit is open, and the air direction can be adjusted by rotating the air deflector, but the size of the air outlet cannot be adjusted, and the adjustment means is less. In order to realize the adjustment of the size of the air outlet, a kind of air supply mechanism and air deflector are disclosed in the related technology, wherein the air supply mechanism comprises a plurality of long strip blades, a middle shell for mounting the blades, and a driving device for driving the relative movement of the plurality of blades;The side of one end of the blade is provided with a sliding shaft and a rotating shaft;The rotating shaft is connected with the driving device and moves with the rotation of the driving device;The middle shell is provided with a first ventilation hole communicating the air inlet side and the air outlet side of the air supply mechanism, the middle shell around the first ventilation hole is provided with a first sliding groove corresponding to the sliding shaft, and the sliding shaft is installed in the first sliding groove, so that the one end of the plurality of blades away from the rotating shaft forms an air outlet;The driving device drives the rotating shaft of the blade to move, and the blade rotates around the sliding shaft as the rotating shaft, to adjust the size of the air outlet. The problem of the related technology is that the plurality of long strip blades are in the form of plane rotation, and at least part of the adjacent blades overlap, and the air flowing through the gap at the overlapping position will cause vibration and noise. In addition, during the rotation of the blade, the overlapping position of the blade deforms, and the blade needs to deform during the rotation, which also leads to the small thickness and poor rigidity of the blade, and the vibration is easy to occur.

[0045] In order to reduce the vibration and noise of the air conditioner when changing the size of the air outlet, in combination with Figures 1-11 As shown in the figure, the disclosure embodiment provides an air outlet assembly, comprising a chassis 100, an air pipe 200, a plurality of baffles 300 and a driving device, wherein the chassis 100 is provided with a first air outlet;The first end of the air pipe 200 is connected with the first air outlet;The plurality of baffles 300 are arranged at the second end of the air pipe 200 and located in the same plane, the plurality of baffles 300 can slide along the radial direction of the air pipe 200, the plurality of baffles 300 slide inward to the first position to jointly block the second end of the air pipe 200, and the plurality of baffles 300 slide outward to the second position to open the second end of the air pipe 200 with the maximum opening;The driving device is used to drive the plurality of baffles 300 to slide between the first position and the second position.

[0046] In the embodiment of the disclosure, the air outlet assembly is installed in the air conditioning device such as fan, air conditioner with air outlet.

[0047] The first air outlet of the chassis 100 is used to connect with the air outlet of the preset installation position, and the first end of the air pipe 200 is connected with the first air outlet of the chassis 100 to realize the connection with the air outlet of the preset installation position.

[0048] The air pipe 200 is a hollow pipe, and its cross section can be polygonal, preferably circular.

[0049] The plurality of baffles 300 are located in the same plane, that is, in no case will overlap occur. Exemplarily, the planar shape of the baffles 300 is a sector of a circle, so that the plurality of baffles 300 can be combined into a circular baffle. The plurality of baffles 300 are arranged at the second end of the air duct 200 and can each move in the radial direction of the air duct 200. The baffles 300 are distributed along a plurality of radial lines of the second end of the air duct 200 and are gathered or spread along the plurality of radial lines of the second end of the air duct 200 when sliding. In this way, the gathering speed and the opening speed of the plurality of first baffles 300 can be improved.

[0050] When the plurality of baffles 300 each move inward to the first position, the plurality of baffles 300 are combined into a closed baffle, thereby blocking the second end of the air duct 200. When the plurality of baffles 300 each move outward to the second position, the projection of the plurality of baffles 300 on the plane of the second end of the air duct 200 is located outside the second end of the air duct 200, thereby causing the second end of the air duct 200 to be opened at the maximum opening degree, that is, causing the air outlet assembly to be opened at the maximum opening degree.

[0051] It should be noted that when the plurality of baffles 300 are located between the first position and the second position, the air outlet assembly is opened at an opening degree smaller than the maximum opening degree of the air outlet assembly. By moving the plurality of baffles 300 between the first position and the second position, not only the opening and closing of the air outlet assembly can be changed, but also the opening degree of the air outlet assembly can be continuously changed by continuous movement of the plurality of baffles 300. In addition, the portion of the plurality of baffles 300 located inward of the second end of the air duct 200 serves as a plurality of sharp ends, which can cause turbulence to the air blown out of the air duct 200, thereby improving the temperature uniformity of the air outlet and making the air feel softer.

[0052] The driving device is used to drive the plurality of baffles 300 to slide between the first position and the second position. By providing the driving device, the opening and closing of the air outlet assembly and the opening degree of the air outlet assembly can be automatically controlled, thereby facilitating the use of the user.

[0053] By using the air outlet assembly provided by the embodiments of the present disclosure, the plurality of baffles 300 are arranged to slide, and the opening and closing of the air outlet assembly and the opening degree of the air outlet assembly can be controlled by the movement of the baffles 300. The plurality of baffles 300 are located in the same plane and slide in the radial direction of the air duct 200, and the adjacent baffles 300 will not overlap. The baffles 300 have high rigidity and are not easy to vibrate. When the plurality of baffles 300 are located between the first position and the second position, the sharp end portion of the baffles is located on the air outlet path of the air duct 200 to cause sharp turbulence. By changing the size of the air outlet through the baffles, the sharp turbulence effect can also be achieved, thereby improving the temperature uniformity of the air outlet and making the air feel softer.

[0054] Optionally, the driving device comprises a driving ring 410, the driving ring 410 is sleeved on the air pipe 200 and is movable along the axial direction of the air pipe 200, the driving ring 410 is provided with a plurality of driving holes 413 corresponding to the plurality of baffles 300, each baffle 300 is provided with a driving pin 310, and the driving ring 410 is movable along the axial direction of the air pipe 200, and the plurality of baffles 300 are driven to move along the radial direction of the air pipe 200 by the driving pins 310.

[0055] The driving ring 410 is used to provide mounting positions for the baffles 300 and drive the baffles 300 to slide. Specifically, the side of the baffle 300 extending towards the air pipe 200 is provided with a driving pin 310, and the driving pin 310 is obliquely arranged. The extension direction of the driving pin 310 is generally along the axial direction of the air pipe 200 and forms a first included angle with the axial line of the air pipe 200. The driving ring 410 is provided with a driving hole 413 corresponding to the driving pin 310 of each baffle 300, and the driving hole 413 is obliquely arranged. The extension direction of the driving pin 310 is generally along the circumferential direction of the air pipe 200 and forms a first included angle with the axial line of the air pipe 200. The driving ring 410 is movable along the axial direction of the air pipe 200. When the driving ring 410 moves towards the second end of the air pipe 200, the driving pin 310 slides in the driving hole 413, thereby driving the baffle to move outward. When the driving ring 410 moves towards the first end of the air pipe 200, the driving pin 310 slides relative to the driving hole 413, thereby driving the baffle to move inward.

[0056] With such a setting form, the driving ring 410 can realize the fixation and driving of the plurality of baffles 300 at the same time. The driving ring 410 is movable along the circumferential direction of the air pipe 200, and the required space for driving is small. The movement of the driving ring 410 along the axial direction of the air pipe 200 is converted into the movement of the plurality of baffles 300 along the radial direction of the air pipe 200, and the transmission ratio of the plurality of baffles 300 can be changed by setting the size of the first included angle, thereby making the movement of the plurality of baffles 300 more accurate.

[0057] In order to realize the driving of the driving ring 410, as an optional implementation form, the driving device comprises a plurality of jacking mechanisms 420, the plurality of jacking mechanisms 420 are distributed along the circumferential direction of the air pipe 200, the first end of the jacking mechanism 420 is connected to the bottom disc 100, and the second end is connected to the driving ring 410, and the plurality of jacking mechanisms 420 are extended and retracted to drive the driving ring 410 to move along the axial direction of the air pipe 200.

[0058] The length of the jacking mechanism 420 itself can be controlled to change. A plurality of jacking mechanisms 420 are arranged circumferentially along the wind pipe 200, which can make the driving ring 410 move synchronously at each position under uniform force, avoiding the driving ring 410 from being skewed and stuck. Specifically, one end of the jacking mechanism 420 is connected to the driving ring 410, and the other end is connected to the chassis 100. When the jacking mechanism 420 extends, it drives the driving ring 410 to move towards the second end of the wind pipe 200, and when the jacking mechanism 420 retracts, it drives the driving ring 410 to move towards the first end of the wind pipe 200. With such a setting form, the driving form is simple and reliable. Exemplarily, the jacking mechanism 420 is a hydraulic cylinder, a gas cylinder or a lead screw structure.

[0059] Alternatively, the wind pipe 200 is configured with external threads, the driving ring 410 is configured with internal threads, and the wind pipe 200 is rotatably arranged on the chassis 100. When the wind pipe 200 rotates, it drives the driving ring 410 to move along the circumference of the wind pipe 200.

[0060] The wind pipe 200 is rotatably arranged on the chassis 100. The outer circle of the wind pipe 200 is configured with external threads, and the driving ring 410 is configured with internal threads. The driving pipe is connected with the wind pipe 200 in a threaded connection. When the wind pipe 200 rotates, the driving ring 410 remains at the initial angle. When the wind pipe 200 rotates bidirectionally, the wind pipe 200 moves bidirectionally along the axial direction of the driving ring 410. In this form, the driving ring 410 and the wind pipe 200 can be regarded as a lead screw structure. The driving ring 410 is connected with the wind pipe 200 in a threaded connection, and the driving ring 410 can maintain good flatness during movement. The wind pipe 200 rotates one circle, and the driving ring 410 moves one pitch. In this way, on the one hand, the torque of the wind pipe 200 rotation can be amplified, and on the other hand, the movement control of the outflow area to the plurality of baffles 300 can be more accurate.

[0061] Alternatively, the driving device comprises a gear ring 430, a driving motor 440 and a driving gear, wherein the gear ring 430 is arranged on the outer circle of the wind pipe 200; the driving motor 440 is fixed to the chassis 100; the driving gear is drivingly connected to the output shaft of the driving motor 440, and when the driving gear rotates, it drives the wind pipe 200 to rotate through the gear ring 430.

[0062] In order to drive the rotation of the air duct 200, the driving device comprises a gear ring 430, a driving motor 440 and a driving gear. The gear ring 430 is sleeved on the outer ring of the air duct 200 and is fixedly connected with the air duct 200, and the gear ring 430 is concentric and coaxial with the air duct 200. When the gear ring 430 rotates in two directions, the air duct 200 is driven to rotate in two directions. The driving gear is connected to the output shaft of the driving motor 440 and is engaged with the gear ring 430. The driving motor 440 rotates in two directions, driving the driving gear to rotate, thereby driving the gear ring 430 to rotate. The rotation of the gear ring 430 drives the air duct 200 to rotate, thereby driving the driving ring 410 to move along the circumference of the air duct 200. The driving ring 410 moves along the circumference of the air duct 200, and the driving pins 310 of the plurality of baffles slide in the sliding grooves of the driving ring 410, thereby driving the plurality of baffles 300 to move along the radial direction of the air duct 200. By adopting such a setting form, the number of motors required by the driving device is less, and the cost of the air outlet assembly is lower.

[0063] Optionally, the driving ring 410 comprises a connecting portion 411 and a threaded portion 412. The connecting portion 411 is provided with a relief hole, and the air duct 200 penetrates the relief hole. The threaded portion 412 extends along the circumference of the relief hole and along the circumference of the air duct 200, and the inner ring of the threaded portion 412 is configured with an internal thread.

[0064] The connecting portion 411 is used to connect the plurality of baffles 300 and drive the plurality of baffles 300. The connecting portion 411 is arranged along a direction parallel to the plane in which the second end of the air duct 200 is located, and the threaded portion 412 extends along the axial direction of the air duct 200. By adopting such a setting form, the threaded portion 412 extends along the axial direction of the air duct 200 for a longer distance, and the driving ring 410 and the air duct 200 can be more firmly screwed.

[0065] Optionally, the first end of the air duct 200 is configured with a flange 210, the gear ring 430 and the flange 210 form a rotation space, and the chassis 100 is embedded in the rotation space.

[0066] The flange 210 of the air duct 200 extends along the radial direction of the air duct 200 from the first end of the air duct 200, and the flange 210 of the air duct 200 can be regarded as a flange plate of the air duct 200. The gear ring 430 is sleeved on the air duct 200 and is located at a distance from the flange 210 of the air duct 200. In this way, an annular rotation space is formed between the gear ring 430 and the flange 210. The chassis 100 is embedded in the rotation space. In the case where the chassis 100 is fixed, the gear ring 430 and the flange 210 jointly fix the air duct 200 to the mounting position. In addition, in the process of rotating the air duct 200, the chassis 100 acts as a track strip, and the rotation of the air duct 200 is realized by the rotation of the gear ring 430 and the flange 210 relative to the chassis 100. By adopting such a setting form, on the one hand, the fixation and rotational connection of the air duct 200 can be realized, and on the other hand, the form of embedding the chassis 100 in the rotation space can reduce the air leakage of the first end of the air duct 200.

[0067] Optionally, the chassis 100 comprises a buckling portion 120 and a clamping portion 130, the clamping portion 130 is provided with the first air outlet and is embedded in the rotating space, the buckling portion 120 extends along the radial direction of the air duct 200 along the side of the clamping portion 130 away from the air duct 200, and the buckling portion 120 and the clamping portion 130 define a buckling space, and the flange 210 of the air duct 200 is located in the buckling space.

[0068] With such a setting form, when the air outlet assembly is fixed to the preset installation position by the chassis 100, the flange 210 of the air duct 200 is not easy to interfere with other structures of the preset installation position, and the flange 210 is not easy to rub with other structures of the preset installation position when the air duct 200 rotates. In addition, the buckling portion 120 can further reduce the air leakage of the first end of the air duct 200.

[0069] Optionally, the driving device further comprises a guide column 600, the guide column 600 extends along the circumferential direction of the air duct 200, and the driving ring 410 is provided with a guide hole 414 corresponding to the guide column 600.

[0070] In order to avoid the driving ring 410 rotating with the air duct 200 when the air duct 200 rotates, the driving device is further provided with a guide column 600. The guide column 600 extends from the chassis 100 to the second end of the air duct 200 along the axial direction of the air duct 200. The driving ring 410 is provided with a guide hole 414 corresponding to the guide column 600, and the guide column 600 penetrates into the guide hole 414. When the air duct 200 rotates, the guide column 600 can prevent the driving ring 410 from rotating with the air duct 200, thereby limiting the movement of the driving ring 410 in the axial direction of the air duct 200. With such a setting form, the reliability of the operation of the air outlet assembly can be further improved.

[0071] Optionally, the guide column is fixed to the chassis and extends radially from the chassis to the air duct.

[0072] With such a setting form, the air outlet assembly can be disassembled as a whole, which facilitates the assembly of the air outlet assembly.

[0073] Optionally, the guide column is fixed to the preset installation position and extends radially from the preset installation position to the air duct.

[0074] With such a setting form, the guide column plays a positioning and pre-fixing effect when the air outlet assembly is installed, which is conducive to assembling the air outlet assembly to the preset installation position.

[0075] Optionally, the driving device comprises a plurality of guide columns 600, the plurality of guide columns 600 are distributed along the circumferential direction of the air duct 200, and the driving ring 410 is provided with a plurality of guide holes 414 corresponding to the plurality of guide columns 600.

[0076] With such a setting form, the partial pressure can be avoided from being too large due to the deflection of the driving ring 410 relative to the air duct 200 when the driving ring 410 rotates.

[0077] Optionally, the air outlet assembly further comprises a cover plate, the cover plate is provided with a second air outlet, the second end of the air duct 200 faces the second air outlet and forms a sliding space with the second end of the air duct 200, and the plurality of baffles 300 are slidingly arranged in the sliding space.

[0078] The cover plate, the driving ring 410 and the air duct 200 jointly fix the plurality of baffles 300. Specifically, the second end of the air duct 200 faces the second air outlet, and the air flowing through the air duct 200 is blown out through the second air outlet. The second end of the air duct 200 is at a predetermined distance from the cover plate, and the sliding space is formed between the second end of the air duct 200 and the cover plate. The plurality of baffles 300 are arranged in the sliding space, and the second end of the air duct 200 and the cover plate limit the movement of the plurality of baffles 300 along the axial direction of the air duct 200. The driving ring 410 limits the movement of the plurality of baffles 300 in the plane of the second end of the air duct 200 through the driving hole 413 and the driving pin 310. With such a setting form, the fixing effect of the air outlet assembly on the plurality of baffles 300 can be improved.

[0079] Optionally, the cross section of the driving hole 413 is elliptical, and the cross section of the driving pin 310 is elliptical.

[0080] With such a setting form, the driving pin 310 can only slide along the length direction of the driving hole 413 in the driving hole 413, and cannot rotate in the driving hole 413. In this way, the rotation of the baffle 300 around the driving pin 310 can be effectively avoided, thereby improving the reliability of the sliding of the baffle 300.

[0081] Optionally, the cross section of the driving hole 413 is a prism, and the cross section of the driving pin 310 is a prism corresponding to the cross section of the driving hole 413.

[0082] With such a setting form, the driving pin 310 can only slide along the length direction of the driving hole 413 in the driving hole 413, and cannot rotate in the driving hole 413. In this way, the rotation of the baffle 300 around the driving pin 310 can also be effectively avoided, thereby improving the reliability of the sliding of the baffle 300.

[0083] Optionally, the outer side of the plurality of baffles 300 is provided with sliding ribs 320, the inner side of the cover plate is provided with a sliding track 510, and the sliding ribs 320 of the plurality of baffles 300 slide along the sliding track 510.

[0084] The inner side of the cover plate is configured with a sliding track 510, and the sliding rib 320 of the baffle 300 slides in the sliding track 510. With such a setting form, when the baffle 300 moves along the radial direction of the air duct 200, the movement of the baffle 300 is limited on a radial line of the air duct 200 by the sliding track 510. In this way, it is beneficial to keep the multiple baffles 300 at a preset angle when the multiple baffles 300 move along the air duct 200, and to avoid the baffle 300 from rotating around the driving pin 310, thereby further improving the reliability of the sliding of the baffle 300.

[0085] In combination with Figure 10 , 11 It is shown that the embodiment of the present disclosure provides an air conditioner, which comprises the above-mentioned air outlet assembly 10.

[0086] Using the air conditioner provided by the embodiment of the present disclosure, the air outlet assembly 10 is slidably provided with multiple baffles 300, and the opening and closing and the opening degree of the air outlet assembly 10 can be controlled through the movement of the baffles 300; the multiple baffles 300 are located on the same plane and slide along the radial direction of the air duct 200, the adjacent baffles 300 do not overlap, and the rigidity of the baffle 300 is strong and is not easy to vibrate; when the multiple baffles 300 are located between the first position and the second position, the tip portion of the blade is located on the air outlet path of the air duct 200 to perform a sharp-piercing disturbance, which can not only change the size of the air outlet through the blade but also play a sharp-piercing disturbance role, thereby improving the temperature uniformity of the air outlet and making the air feeling more soft.

[0087] Optionally, the guide column extends from the fan box along the radial direction of the air duct.

[0088] In this way, the assembly of the air outlet assembly can be more convenient.

[0089] Optionally, the air conditioner comprises a shell 20, a fan box 30 and the above-mentioned air outlet assembly 10, wherein the shell 20 is configured with a containing space; the fan box 30 is arranged in the containing space, and the fan box 30 and the shell 20 form a sandwich layer; and the above-mentioned air outlet assembly 10 is arranged in the sandwich layer.

[0090] The fan box 30 arranged independently can improve the air outlet static pressure of the air conditioner, which is beneficial to improve the air supply amount of the air conditioner and increase the air supply distance of the air conditioner. The air outlet assembly 10 is arranged in the sandwich layer, and is used to guide the air blown out by the fan box 30 to the air outlet of the shell 20 at a certain angle. The movement of the baffle 300 of the air outlet assembly 10 is neither performed inside the fan box 30 nor performed outside the shell 20, and the movement of each moving part of the air outlet assembly 10 is not easy to be interfered.
