[0002] Air conditioners are widely used to regulate indoor temperatures. Existing air conditioners typically have guide vanes at the air duct openings. Adjusting the vanes' direction of airflow adjusts the airflow direction. However, due to limitations in duct installation space and the vane's structure, existing vanes have a small airflow area and poor airflow guidance. Summary of the Invention

[0003] The purpose of the present invention includes providing an air outlet device and an air conditioner to solve the technical problem that the air guide blades in the existing air conditioner have a small air guide area for the air outlet of the air duct and a poor air guide effect.

DETAILED DESCRIPTION

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following detailed description of the specific embodiments of the present invention is given in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] This embodiment provides an air outlet device 50, which is applied to an air conditioner, such as Figure 4 、 Figure 6 and Figure 8 As shown, it includes a base 100, an air outlet grille 200 and a plurality of swing blades 300. The base 100, the air outlet grille 200 and the plurality of swing blades 300 are integrally formed, wherein the base 100 is located on one side of the width direction of the air outlet grille 200, and the plurality of swing blades 300 are all located on the downstream side of the air outlet grille 200 and are arranged at intervals along the length direction of the air outlet grille 200. The swing blades 300 have a flexible portion 320 that can be elastically bent to make it swing.

[0041] When the air outlet device 50 is applied to an air conditioner, Figure 1 、 Figure 2 and Figure 7As shown, the air conditioner includes a shell 10 and the above-mentioned air outlet device 50, the shell 10 has an air duct 11, the base 100 of the air outlet device 50 is fixed to the air duct wall of the air duct 11, and the air outlet grille 200 is blocked in the air duct 11; during use, the air outlet grille 200 is used to block and protect the air duct opening 12 area, so as to reduce the occurrence of user misoperation by putting their hands into the air duct 11 and causing injuries such as the cross-flow fan 40, thereby improving the safety of the air conditioner; the air blown out of the air duct 11 passes through the air outlet grille 200 and reaches the swing blade 300, and adjusting the rotation angle of the swing blade 300 around the flexible portion 320 can adjust its air guide direction, thereby changing the air outlet direction of the air conditioner, wherein the side of the air outlet grille 200 facing the air duct 11 is the upstream side, and the side facing the outside of the air conditioner is the downstream side.

[0042] Among them, the base 100, the air outlet grille 200 and the plurality of swing blades 300 are integrally formed. On the one hand, the three are integrally formed, and the flexible portion 320 of the swing blade 300 can be elastically bent so that the swing blade 300 can swing around the flexible portion 320. On the basis of ensuring that the swing blade 300 can adjust the diversion direction, the processing convenience of the three is higher; at the same time, when the air conditioner is assembled, there is no need to assemble the base 100, the air outlet grille 200 and the swing blade 300, and the air outlet grille 200 and the swing blade 300 can be assembled at the same time by only connecting the base 100 to the air duct wall, thereby improving the assembly convenience and efficiency of the air conditioner, and ensuring that the base 100, the air outlet grille 200 The relative position accuracy of the pendulum blade 300 ensures the effective blocking of the air duct 11 by the air outlet grille 200 and the effective guidance of the air outlet of the air duct 11 by the pendulum blade 300; on the other hand, compared with the existing pendulum blade 300 which generally requires a connecting arm for connection, the pendulum blade 300 of the present application is integrally formed on the downstream side of the air outlet grille 200 without the need for a connecting arm, and at the same time, the pendulum blade 300 is seamlessly connected to the air outlet grille 200, thereby increasing the width and length of the pendulum blade 300 within the limited space of the air duct 11, correspondingly increasing the air guide area of the pendulum blade 300 and reducing the amount of air leakage between the air outlet grille 200 and the pendulum blade 300 during the air guide process, thereby effectively improving the air guide effect of the pendulum blade 300.

[0043] Specifically, taking a vertical air conditioner as an example, the air outlet device 50 is mounted on the housing 10 of the vertical air conditioner. The air outlet grille 200 has a width along the horizontal direction and a length along the vertical direction. The connection between the swing blade 300 and the air outlet grille 200 extends along the horizontal direction, and the swing blade 300 can swing up and down around the flexible portion 320. Of course, the air conditioner can also be a wall-mounted air conditioner or other types of air conditioners.

[0044] Specifically, in this embodiment, Figure 3As shown, a first drive assembly 20 can be provided in the housing 10. The first drive assembly 20 includes a drive motor and a linkage rod connected to the drive end of the drive motor. The linkage rod is provided with a plurality of latch holes spaced apart along its length. Each pendulum blade 300 is integrally formed with a linkage shaft 333. The plurality of linkage shafts 333 are rotatably engaged with the plurality of latch holes in a one-to-one correspondence. This is one specific form of driving the pendulum blade 200 to swing. The length direction of the linkage rod is consistent with the length direction of the air outlet grille 200. Each pendulum blade 300 is rotatably connected to the latch hole of the linkage rod via the linkage shaft 333. When the swing angle of the pendulum blade 300 needs to be adjusted, the first drive assembly 20 drives the linkage rod to move along its length. While each linkage shaft 333 rotates relative to the latch hole, it is pulled up and down synchronously by the linkage rod, thereby driving each pendulum blade 300 to swing up and down synchronously.

[0045] Among them, preferably, Figure 3 As shown, the edge of the swing blade 300 facing away from the air outlet grille 200 is parallel to the plane where the air duct opening 12 is located, the linkage shaft 333 is located in the middle area of the edge, and the axial direction of the linkage shaft 333 is consistent with the width direction of the air outlet grille 200.

[0046] Optionally, in this embodiment, if Figure 6 As shown, the flexible portion 320 is provided with a through hole 321. The provision of the through hole 321 can reduce the area of the flexible portion 320, thereby improving the deformation capacity of the flexible portion 320, correspondingly reducing the resistance of the swing blade 300 to the swing around the flexible portion 320, improving the smoothness of the swing blade 300's swing around the flexible portion 320, and reducing the driving load of the first driving assembly 20.

[0047] Specifically, in this embodiment, Figure 6As shown, the through hole 321 is a strip-shaped hole and includes a middle extension section 321a and two end extension sections 321b. The middle extension section 321a extends along the width direction of the air outlet grille 200, and the two end extension sections 321b are connected to the two ends of the middle extension section 321a in a one-to-one manner and both extend away from the air outlet grille 200. The flexible portion 320 serves as the swing axis for the swing blade 300 to swing. Flexible connecting arms 322 can be formed between the end extension section 321b and the corresponding side edge of the flexible portion 320, and between the adjacent internal extension sections 321d at both ends of two adjacent through holes 321 when there is more than one through hole 321. Then, the sum of the widths of each flexible connecting arm 322 along the width direction of the air outlet grille 200 is the effective length of the swing axis, and the length of each flexible connecting arm 322 along the direction away from the air outlet grille 200 is the effective elastic bending length. Among them, on the one hand, the middle extension section 321a is provided to extend along the width direction of the air outlet grille 200, which can effectively shorten the swing axis on the basis of ensuring the connection function of the flexible portion 320. The effective length of the swing shaft effectively improves the flexible deformation capacity of the swing axis, improves the smoothness of the swing blade 300 swinging around the swing shaft, and reduces the driving load of the first drive component 20; on the other hand, when the end extension section 321b is provided, the area between the two is still used as the effective swing area of the swing blade 300. On the basis of ensuring the extension length of the swing blade 300 away from the air outlet grille 200, the length of the flexible connecting arm 322 can be increased, that is, the effective elastic bending length is increased, so as to further improve the flexible deformation capacity of the flexible part 320 on the basis of ensuring the air guide area of the swing blade 300, improve the smoothness of the swing of the swing blade 300 around the flexible connecting arm 322, and reduce the driving load of the first drive component 20.

[0048] Specifically, in this embodiment, Figure 6 As shown, there are at least two through-holes 321. Each through-hole 321 is spaced apart along the width of the air outlet grille 200. Of the end extensions 321b, two on either side are edge extensions 321c, and the remaining are internal extensions 321d. The internal extensions 321d extend longer than the edge extensions 321c. The flexible connecting arms 322 formed between the two edge extensions 321c on either side of the width and the edges of the corresponding side of the flexible portion 320 are relatively short to ensure the stability of the connection between the flexible portion 320 and its outer region. The flexible connecting arm 322 formed between the adjacent middle extensions 321a (i.e., the internal extensions 321d) of two adjacent through-holes 321 is relatively long to further enhance its flexible deformation capability, thereby further improving the smoothness of the swing blade 300's swing about the flexible connecting arms 322 and reducing the driving load of the first drive assembly 20.

[0049] Please refer to Figure 5 and Figure 6As shown, the area where the swing blade 300 is connected between the flexible part 320 and the air outlet grille 200 is the connecting part 310, and flexible connecting arms 322 are formed between the edge extension section 321c and the corresponding side edge of the flexible part 320 and between the two adjacent internal extension sections 321d in the two adjacent through holes 321. The area of the swing blade 300 located on the side of the flexible connecting arm 322 and the through hole 321 away from the air outlet grille 200 is the swing part 330. The arrangement of each end extension section 321b is based on improving the deformation ability of the flexible part 320, and the degree of reduction in the effective air guide area of the swing part 330 is small, which can accordingly ensure that the swing blade 300 has a larger air guide area.

[0050] Specifically, if Figure 5 As shown, the connecting portion 310 is smoothly connected to the flexible portion 320, and its thickness gradually increases in the direction away from the flexible portion 320, thereby ensuring that the flexible portion 320 has a smaller thickness and higher elastic deformation capacity. The connecting portion 310 can not only achieve a smooth connection with the flexible portion 320, but also ensure the firmness of the connection with the air outlet grille 200, and accordingly ensure the smoothness of the swinging portion 330 swinging around the flexible portion 320 and ensure the firmness of the swing blade 300 connected to the air outlet grille 200.

[0051] Similarly, a transition zone 331 is provided in the region corresponding to the swing portion 330, the flexible connecting arm 322, and the end extension 321b. This transition zone 331 smoothly transitions to the corresponding flexible connecting arm 322, and its thickness gradually decreases toward the flexible connecting arm 322. The region of the swing portion 330 that differs from the transition zone 331 is a reinforcement zone 332. The thickness of the reinforcement zone 332 is greater than that of the flexible portion 320 to ensure the strength and wind direction of the swing portion 330 and reduce the possibility of bending deformation during wind-guiding that could affect the wind direction. The provision of the transition zone 331 ensures a smooth connection between the reinforcement zone 332 and the flexible portion 320, ensuring smooth demolding of the swing blade 300.

[0052] Specifically, the thickness of the flexible portion 320 may be 0.4 mm to 0.6 mm, the thickness of the reinforcement area 332 may be 2 mm to 2.2 mm, and the thickness of the connecting portion 310 and the transition connecting area 331 may both range from 0.4 mm to 2.2 mm.

[0053] In this embodiment, the ratio of the extended lengths of the connecting portion 310, the flexible portion 320, and the swinging portion 330, in a direction away from the air outlet grille 200, ranges from 1:1.5 to 2.5:9 to 11; preferably, it is 1:2:10. This ensures a secure connection between the connecting portion 310 and the air outlet grille 200, thereby improving the stability of the swing blade 300 connected to the air outlet grille 200. The flexible portion 320 has a high elastic deformation capacity, allowing the swinging portion 330 to swing smoothly and reducing the driving load of the first drive assembly 20. The swinging portion 330 also has a large air guide area, thereby improving its air guide effect.

[0054] Optionally, in this embodiment, the length of the blade 300 extending from its flexible portion 320 away from the air outlet grille 200 is greater than the distance between two adjacent blades 300. When the blades 300 are raised or lowered, there is always an overlapping area between adjacent blades 300, forming an effective air guide channel with a smaller width, thereby improving the air guide effect of the blades 300.

[0055] This embodiment also provides an air conditioner, including a housing 10 and the above-mentioned air outlet device, the housing 10 has an air duct 11, the base 100 of the air outlet device is fixed to the air duct wall of the air duct 11, and the air outlet grille 200 is blocked from the air duct 11; Figure 2 、 Figure 3 and Figure 10 As shown, the air duct 11 is located downstream of the air outlet device 50 and is rotatably connected to a plurality of air guide plates 30. The plurality of air guide plates 30 are spaced apart along the width direction of the air duct 11, and the axial direction of their rotation shafts 31 is consistent with the length direction of the air duct 11. The housing 10 is provided with a second drive assembly, the driving end of which is connected to each air guide plate 30 for driving the air guide plates 30 to rotate. The swing direction of the swing blade 300 and the swing direction of the air guide plate 30 are arranged approximately perpendicularly. During use, the air outlet direction can be adjusted to different directions by adjusting the swing angle of the swing blade 300 and the rotation angle of the air guide plate 30, thereby improving the air outlet direction adjustment effect of the air conditioner and obtaining more air guide modes.

[0056] Specifically, in this embodiment, Figure 2-Figure 5As shown, the air conditioner is a vertical air conditioner and includes a remote-throw mode. In remote-throw mode, the blades 300 are all horizontal, and the air guide plate 30 directs air perpendicularly to the plane of the air duct opening 12 of the air duct 11. When cooling or heating is required in an indoor area such as the kitchen, which is relatively far from the air conditioner, the air conditioner can be adjusted to remote-throw mode. The first drive assembly 20 accordingly drives the blades 300 to swing up and down to a nearly horizontal position, while the air guide plate 30, driven by the second drive assembly, rotates to a position approximately perpendicular to the plane of the air duct opening 12. The airflow exiting the air duct 11 is then approximately parallel to the air guide surfaces of the blades 300 and the air guide plate 30. Therefore, the blades 300 and the air guide plate 30 do not deflect or slow the airflow, and the airflow can be sequentially delivered outward along the air guide surfaces of the blades 300 and the air guide plate 30 over a greater distance, thereby increasing the air supply distance of the air conditioner and achieving temperature regulation in a more distant area.

[0057] In this embodiment, the air conditioner also includes a long-range and short-range soft mode. In the long-range and short-range soft mode, Figure 7-Figure 9 As shown, each of the swing blades 300 is raised 40° to 50°, and the air guiding direction of the air guide plate 30 is perpendicular to the plane of the air duct opening 12 of the air duct 11. When the user is at a relatively close distance in front of the air conditioner, the air conditioner can be adjusted to enter the long-range and near-range soft mode. The first drive component 20 correspondingly drives the swing blades 300 to swing upward 40° to 50° relative to the horizontal position. The air guide plate 30 is driven by the second drive component to rotate to a position approximately perpendicular to the plane of the air duct opening 12. The airflow blown out through the air duct 11 first flows upward under the guidance of the swing blades 300, and then is sent forward to a longer distance under the guidance of the air guide plate 30. As a result, the wind speed in the area near the front of the air conditioner is gentle, achieving the effect of no blow on the head and comfortable air supply. Specifically, in the long-range and near-range soft mode, the soft wind speed in the area within 1.2m of the air conditioner is approximately 0.5m / s.

[0058] Specifically, if Figure 9As shown, the extension length of the swing blade 300 from its flexible portion 320 away from the air outlet grille 200 is L, and the spacing between two adjacent swing blades 300 is h. In the long-range and near-range soft mode, the upward angle of the swing blade 300 is θ, and h-5≤sinθ·L≤h. Among them, the total extension length of the flexible portion 320 and the swing portion 330 is L. The extension length L determines the diversion length and air supply distance of the swing blade 300 for the air outlet of the air duct 11. The larger the extension length, the larger the diversion length, and the longer the air supply distance, the better the near-range soft effect. The spacing h between two adjacent swing blades 300 determines the number of swing blades 300 on the air outlet grille 200. The larger the number, the higher the driving load requirement for the first drive assembly 20, and the smaller the ventilation volume of the air duct 11. The upward angle θ of the swing blade 300 determines the diversion direction and air supply distance of the air outlet of the air duct 11 by the swing blade 300. Within a certain range, the larger the upward angle θ, the longer the air supply distance. Taking the above three factors into comprehensive consideration, setting L>h and h-5≤sinθ·L≤h can obtain appropriate ventilation volume and appropriate driving load for the first drive component 20. At the same time, in the long-range and near-soft mode, the area close to the air conditioner can obtain comfortable air supply and better soft wind effect.

[0059] Specifically, h may be 40 to 50 cm, and L may be 50 to 65 cm.

[0060] In this embodiment, air duct 11 is further equipped with a sweeping assembly and a third drive assembly upstream of air outlet device 50. The sweeping assembly includes a plurality of sweeping blades spaced apart along the length of air duct 11. The drive end of the third drive assembly is connected to each sweeping blade, driving the sweeping blades to rotate up and down. During operation, the sweeping blades of the sweeping assembly, driven by the third drive assembly, rotate up and down to perform a primary wind diversion adjustment on the air outlet of air duct 11 upstream of pendulum blade 300. After the primary wind diversion, the airflow then flows to pendulum blade 300, where it undergoes a secondary wind diversion adjustment, thereby improving the airflow diversion effect of the air conditioner on the upward or downward movement of the air outlet.

[0061] Specifically, in the long-throw and short-throw soft mode, the wind-sweeping blades can be raised by 35° to 55°.

[0062] Optionally, in this embodiment, if Figure 4As shown, the air outlet grille 200 includes a plurality of first grille bars 210 and a plurality of second grille bars 220 arranged crosswise. Among the plurality of first grille bars 210, the two first grille bars 210 located on both sides are end grille bars 211, and the remaining first grille bars 210 are middle grille bars 212. The first ends of the middle grille bars 212 all extend out of the second grille bars 220, and the base 100 is connected to the first end of each middle grille bar 212; the connecting parts 310 of the plurality of swing blades 300 are connected one-to-one with the downstream sides of the plurality of middle grille bars 212. The first grille bar 210 and the second grille bar 220 respectively serve as horizontal and vertical grille bars to form a mesh-shaped air outlet grille 200, so as to achieve isolation and protection of the air duct 11 on the basis of ensuring the ventilation effect of the air duct 11, and the middle grille bar 212 also serves to connect the base 100, the air outlet grille 200 and the swing blade 300; wherein, the length extension direction of the first grille bar 210 is the width direction of the air outlet grille 200, and the length extension direction of the second grille bar 220 is the length direction of the air outlet grille 200.

[0063] In this embodiment, the sidewall surfaces of each second grid bar 220 facing toward and away from the base 100 are parallel to the width direction of the base 100 , so as to facilitate the overall demolding of the air outlet device 50 and improve the product yield.

[0064] Preferably, when the air conditioner is in standby or off mode, the swing angle of the swing blade 300 is equal to its ejection angle. When the air conditioner enters the standby or off mode, the first drive assembly 20 drives the swing blade 300 to swing to the ejection position. At this point, the position of the swing blade 300 relative to the air outlet grille 200 is the same as the relative position of the swing blade 300 and the air outlet grille 200 when the air outlet device 50 was ejected from the mold. Therefore, the flexible portion 320 does not undergo elastic bending deformation, thereby reducing stress fatigue of the flexible portion 320 and correspondingly increasing its service life.

[0065] Optionally, in this embodiment, if Figure 4 As shown, the edges of the pendulum blade 300 facing and facing away from the base 100 are both parallel to the width direction of the base 100. The base 100 is approximately attached to the air duct wall, and its width extension direction is approximately parallel to the direction of the air duct wall. Therefore, the two side edges of the pendulum blade 300 in the width direction are approximately parallel to the air duct wall on the corresponding side of the air duct 11. There is a gap between the edge of the pendulum blade 300 facing the base 100 and the base 100, and between the edge of the pendulum blade 300 facing away from the base 100 and the air duct wall on the corresponding side of the air duct 11. The shape of the pendulum blade 300 is adapted to the shape of the air duct 11. On the basis of ensuring the swing of the pendulum blade 300, its air guide area can be further increased, and its air guide effect can be further improved accordingly.

[0066] Specifically, in this embodiment, Figure 6As shown, the edge of the oscillating blade 300 facing the base 100 is defined as the facing edge 340. The facing edge 340 includes a first edge segment 341, a second edge segment 342, and a third edge segment 343 along a direction away from the air outlet grille 200. The second edge segment 342 is parallel to the width of the base 100, and both the first edge segment 341 and the third edge segment 343 are inclined away from the base 100 in a direction away from the second edge segment 342. The distal end of the facing edge 340 is farther from the base 100 than the central portion, reducing the probability of interference between the oscillating blade 300 and the base 100 during its swing, thereby further ensuring smooth swinging of the oscillating blade 300.

[0067] In this embodiment, Figure 1 、 Figure 2 and Figure 7 As shown, two air outlet devices 50 can be provided, arranged sequentially along the length of the air duct 11. Providing two air outlet devices 50 shortens the length of each air outlet device 50, thereby improving processing convenience and mold yield. Specifically, the length of the air duct 11 is approximately 900 cm, and the length of the two air outlet devices 50 is approximately 450 cm.
