Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air outlet device and a vertical air conditioner. Background Art

[0002] Air conditioners are widely used for regulating indoor temperatures. Existing air conditioners typically have guide vanes at the air duct opening to adjust the airflow direction and intensity. To achieve a gentle, zero-wind mode, existing air conditioners typically employ micro-holes in the guide vanes. In zero-wind mode, these vanes block the air duct, allowing air to flow outward through the micro-holes, creating a certain amount of airflow near the front of the air conditioner. However, due to the low airflow volume, areas further away from the air conditioner experience near-zero-wind mode, effectively eliminating the need for zero-wind mode and resulting in poor temperature regulation. Summary of the Invention

[0003] The purpose of the present invention includes providing an air outlet device and a vertical air conditioner to solve the technical problem that in the zero wind mode of the existing air conditioner, the area far away from the air conditioner actually has almost no air flow and does not reach the zero wind mode, and the temperature regulation effect is poor.

[0004] In order to solve the above problems, the present invention provides an air outlet device, which is applied to a vertical air conditioner, including an air outlet grille and a plurality of swing blades integrally formed on the air outlet side of the air outlet grille and arranged at intervals along its height direction. The swing blades include an extension portion and a swing portion, both of which are connected to the air outlet grille, wherein the extension portion extends horizontally away from the air outlet grille, and the swing portion has a flexible section that can be elastically bent to swing up and down.

[0005] Optionally, the area of the swinging portion located between the flexible section and the air outlet grille is the connecting section, and the area of the flexible section located on the side away from the air outlet grille is the swinging section. The flexible section includes a flexible arm connected to the connecting section and extending away from the connecting section.

[0007] Optionally, when the extending portion corresponds to the swinging portion in position, there are avoidance gaps between the extending portion and the dominant wind area, the adjacent flexible arms and the adjacent connecting arms.

[0008] Optionally, the avoidance gap formed between the extension portion and the flexible arm is a first gap, and the first gap extends toward one end of the connecting section away from the adjacent extension portion to form an extension gap.

[0009] Optionally, the connecting section is smoothly connected to the flexible arm, and its thickness gradually increases in a direction away from the flexible arm;

[0010] And / or, the connecting arm is smoothly connected to the flexible arm, and the thickness of the connecting arm gradually decreases in a direction toward the flexible arm.

[0011] Optionally, the air outlet device further includes a base, and the base is integrally formed on one side of the air outlet grille in the width direction.

[0012] Optionally, the air outlet grille includes a plurality of cross-arranged horizontal grille bars and a plurality of vertical grille bars, and the side walls of the vertical grille bars facing toward and away from the base are parallel to the width direction of the base.

[0013] Optionally, the air outlet device also includes a base, which is integrally formed on one side of the air outlet grille in the width direction; the edge of the swinging portion facing the base is a facing edge, and the facing edge includes a first edge segment, a second edge segment and a third edge segment along the direction away from the air outlet grille, the second edge segment is parallel to the width direction of the base, and the first edge segment and the third edge segment are both inclined away from the base in the direction away from the second edge segment.

[0014] Optionally, an extension length of the swing portion from the flexible section away from the air outlet grille is greater than a distance between two adjacent swing portions.

[0015] The present invention also provides a vertical air conditioner, comprising a shell and the above-mentioned air outlet device, wherein the shell has an air duct, and the air outlet grille of the air outlet device is blocked from the air duct.

[0016] Optionally, the air duct is further rotatably connected to a plurality of air guide plates located downstream of the air outlet device, and the plurality of air guide plates are arranged at intervals along the width direction of the air duct and their rotation axes extend along the vertical direction.

When a user wants to adjust the indoor environment to a gentle breeze, the floor-standing air conditioner can be adjusted to enter a zero wind mode. Specifically, the swing portion is adjusted to rotate upward by a certain angle. Then, the swing portion of each swing blade is in an upward state, while the extension portion remains in a forward horizontal extension state. Part of the airflow blown out through the air duct can be blown upward under the wind guiding action of the swing portion, while the other part of the airflow is blown forward horizontally under the wind guiding action of the extension portion.

DETAILED DESCRIPTION

[0035] 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.

[0036] This embodiment provides an air outlet device 50, which is applied to a vertical air conditioner, such as Figure 2 、 Figure 7 and Figure 9As shown, it includes an air outlet grille 100 and a plurality of swing blades 200 integrally formed on the air outlet side of the air outlet grille 100 and arranged at intervals along its height direction. The swing blade 200 includes an extension portion 210 and a swing portion 220 both connected to the air outlet grille 100, wherein the extension portion 210 extends horizontally away from the air outlet grille 100, and the swing portion 220 has a flexible section 222 that can be elastically bent to swing up and down.

[0037] This embodiment also provides a vertical air conditioner, such as Figure 1 、 Figure 5 and Figure 6 As shown, it includes a shell 10, a first drive component and the above-mentioned air outlet device 50, the shell 10 has an air duct 11, the air outlet grille 100 of the air outlet device 50 is blocked in the air duct 11, the first drive component is fixed to the shell 10 and its drive end is connected to each swing part 220 of the air outlet device 50, for driving the swing part 220 to swing up and down around its flexible section 222.

[0038] This embodiment provides an air outlet device 50 and a vertical air conditioner, wherein the air outlet device 50 includes an air outlet grille 100 for blocking the air duct opening 12 and a swing blade 200 for guiding the air outlet. The air conditioner includes a shell 10 as an installation base and an air duct 11 formed inside, the above-mentioned air outlet device 50 and a first drive component for driving the swing blade 200 to swing to change the diversion direction.

[0039] When the air outlet device 50 is applied to a vertical air conditioner, during use, the air outlet grille 100 is used to provide a barrier and protection for the air duct opening 12 area, so as to reduce the occurrence of user error in inserting the hand into the air duct 11 and causing injury by the cross-flow fan 40, thereby improving the safety of use of the vertical air conditioner; the air blown out of the air duct 11 passes through the air outlet grille 100 and reaches the swing blade 200, and the first drive component adjusts the rotation angle of the swing part 220 around the flexible section 222 to adjust its air guide direction, thereby changing the air outlet direction of the vertical air conditioner, wherein the side of the air outlet grille 100 facing the air duct 11 is the air inlet side, and the side facing the outside of the air duct 11 is the air outlet side.

[0040] Specifically, when the user wants to adjust the indoor environment to a gentle breeze, the user can adjust the vertical air conditioner to enter the zero wind mode, such as Figure 2-Figure 4As shown, specifically, the first driving component drives the swing part 220 to rotate upward by a certain angle, so that the swing part 220 of each swing blade 200 is in an upward state, and the extension part 210 still maintains a horizontal extension state forward, and a part of the airflow blown out through the air duct 11 can be blown out in an upward state under the wind guiding effect of the swing part 220, and the other part of the airflow is blown out horizontally forward under the guide effect of the extension part 210, wherein the plurality of swing blades 200 are arranged at intervals in the vertical direction, so that the airflow blown upward through the lower swing part 220 can be blown out by the upper extension part 210. The airflows blown out horizontally from the extension part 210 cross and collide, and the two airflows have the effect of breaking up and slowing down each other. At the same time, under the horizontal extension air supply effect of the extension part 210, the area closer to the front side of the vertical air conditioner has a softer airflow blowing through it. Under the upward long-distance air casting effect of the swing part 220, the area farther away from the vertical air conditioner also has a softer airflow blowing through it, so that the entire area of the room is in a gentle wind feeling state, thereby ensuring the temperature regulation effect of the vertical air conditioner on the entire area of the room and the comfort of the user in various areas of the room.

[0041] Of course, in addition to the above-mentioned zero wind mode, the vertical air conditioner of the present application can also adjust the swing portion 220 to swing to other positions through the first driving component, specifically, Figure 8 As shown, when an area such as a kitchen that is far away from the vertical air conditioner needs to be cooled or heated, the swing portion 220 can be driven by the first drive assembly to rotate to an approximately horizontal position. At this time, the extension portion 210 and the swing portion 220 are in corresponding positions, and the swing blade 200 extends horizontally as a whole to guide the wind forward. The air flow blown out through the air duct 11 can be blown out to a farther distance under the horizontal guidance of the swing blade 200, thereby achieving rapid temperature adjustment of the farther area; or, when an area closer to the front of the vertical air conditioner needs to be cooled or heated quickly, the swing portion 220 can be driven by the first drive assembly to rotate downward by a certain angle. At this time, the extension portion 210 Maintaining a forward horizontal extension state, the swinging portion 220 is in a downward-leaning state. A portion of the airflow blown out through the air duct 11 can be blown downward under the wind-guiding effect of the swinging portion 220, and the other portion of the airflow is blown forward horizontally under the guiding effect of the extension portion 210. The airflow blown downward through the upper swinging portion 220 can cross-collide with the airflow blown horizontally outward from the lower extension portion 210. The two airflows break up and decelerate each other to form an airflow group with a lower flow rate and a soft wind feeling. The airflow group generally flows forward and downward to a relatively close area on the front side of the vertical air conditioner, thereby achieving rapid temperature adjustment in the area with a soft wind feeling and a high degree of comfort.

[0042] At the same time, the air outlet grille 100 and the plurality of swing blades 200 are integrally formed. On the one hand, the two are integrally formed, and the flexible section 222 of the swing blade 200 can be elastically bent so that the swing portion 220 can swing around the flexible section 222. On the basis of ensuring that the swing portion 220 can adjust the diversion direction, the processing convenience of the two is higher; at the same time, when assembling the air conditioner, there is no need to assemble the air outlet grille 100 and the swing blade 200 separately, and the assembly of the swing blade 200 can be achieved at the same time by only connecting the air outlet grille 100 to the wall of the air duct 11, thereby improving the assembly convenience and efficiency of the vertical air conditioner, and ensuring the relative position of the air outlet grille 100 and the swing blade 200. The positioning accuracy ensures that the air outlet grille 100 effectively blocks the air duct 11 and the pendulum blade 200 effectively guides the air out of the air duct 11; on the other hand, compared with the existing pendulum blade 200 which generally requires an extension arm for connection, the pendulum blade 200 of the present application is integrally formed on the downstream side of the air outlet grille 100 without the need for an extension arm. At the same time, the pendulum blade 200 is seamlessly connected to the air outlet grille 100, thereby increasing the width and length of the pendulum blade 200 within the limited space of the air duct 11, correspondingly increasing the air guide area of the pendulum blade 200 and reducing the amount of air leakage between the air outlet grille 100 and the pendulum blade 200 during the air guide process, thereby effectively improving the air guide effect of the pendulum blade 200.

[0043] Specifically, in this embodiment, the first drive assembly 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 locking holes spaced apart along its length. Each swinging portion 220 is integrally formed with a linkage shaft 226. The plurality of linkage shafts 226 are rotatably engaged with the plurality of locking holes in a one-to-one correspondence. This is one specific form of the first drive assembly. The linkage rod extends in the vertical direction, and each swinging portion 220 is rotatably connected to the locking hole of the linkage rod via the linkage shaft 226. When the swing angle of the swinging portion 220 needs to be adjusted, the first drive assembly drives the linkage rod to move along its length. Each linkage shaft 226 rotates relative to the locking hole and is simultaneously pulled up and down by the linkage rod, thereby driving each swinging portion 220 to swing up and down synchronously.

[0044] Preferably, the edge of the swing portion 220 facing away from the air outlet grille 100 is parallel to the plane where the air duct opening 12 is located, the linkage shaft 226 is located on the edge, and the axial direction of the linkage shaft 226 is consistent with the width direction of the air outlet grille 100.

[0045] Specifically, in this embodiment, Figure 2 、 Figure 3 and Figure 7-Figure 9As shown, the area of the swinging portion 220 between the flexible section 222 and the air outlet grille 100 is the connecting section 221, and the area of the flexible section 222 on the side facing away from the air outlet grille 100 is the swinging portion 223. The flexible section 222 includes a flexible arm 222a connected to the connecting section 221 and extending away from the connecting section 221. The swinging portion 223 includes a main airflow area 223b and a connecting arm 223a connected between the flexible arm 222a and the main airflow area 223b. The main airflow area 223b occupies a larger area of the swinging portion 220, serving as the primary airflow guide area. The entire strip-shaped arm formed by the connection between the flexible arm 222a and the connecting arm 223a is located on one side of the extension portion 210 in the width direction, ensuring that the swinging portion 220 does not interfere with the extension portion 210 when swinging up and down relative to the extension portion 210. The connecting section 221 serves as the base of the swinging portion 220, connecting the flexible arm 222a to the air outlet grille 100 and ensuring a secure connection.

[0046] In this embodiment, Figure 9 As shown, there can be multiple flexible arms 222a, and the multiple flexible arms 222a are arranged at intervals along the width direction of the air outlet grille 100, and there is an extension portion 210 between every two adjacent flexible arms 222a; the number of connecting arms 223a and the flexible arms 222a is equal and they are connected one-to-one. The multiple extension portions 210 and the multiple flexible arms 222a are arranged alternately in sequence, and the flexible arms 222a are located on both sides along the width direction of the air outlet grille 100, and the extension portions 210 are all located in the inner area of the swing blade 200; on the one hand, the dispersed flexible arms 222a can ensure the stability of the swing portion 220 connected to the air outlet grille 100, and reduce the occurrence of large deviations in the air guide direction caused by local offset during the swinging process of the swing portion 220; at the same time, the dispersed flexible arms 222a have a smaller width and a higher elastic deformation capacity, so that The resistance of the swinging section 223 to the up and down swinging around the flexible section 222 is increased, thereby correspondingly improving the swinging smoothness of the swinging section 223 and reducing the driving load of the first driving component on the swinging part 220; on the other hand, multiple extension parts 210 are dispersedly arranged, and the corresponding positions of the swinging part 220 and the extension part 210 form a vent 225. Accordingly, multiple vents 225 are dispersedly arranged, thereby improving the uniformity of the mutual disturbance of the two airflows in the zero wind mode, and correspondingly further improving the soft wind effect in various areas of the room in the zero wind mode, thereby improving the comfort of users in various areas.

[0047] Preferably, if Figure 9 As shown, the left edge of the dominant wind zone 223b is coplanar with the left edge of the leftmost one of the multiple flexible arms 222a, and the right edge is coplanar with the right edge of the rightmost one of the multiple flexible arms 222a, thereby ensuring the connection stability of the flexible arm 222a to the dominant wind zone 223b and increasing the width of the dominant wind zone 223b as much as possible, increasing its wind-guiding area and improving its wind-guiding effect.

[0048] Optionally, in this embodiment, if Figure 9 As shown, when the extension portion 210 and the swing portion 220 are positioned correspondingly, there are clearance gaps 230 between the extension portion 210 and the main airflow area 223b, the adjacent flexible arm 222a, and the adjacent connecting arm 223a. When the swing portion 220 swings up and down relative to the extension portion 210, the presence of the clearance gaps 230 prevents interference between the extension portion 210 and the flexible arm 222a, the connecting arm 223a, and the main airflow area 223b. This ensures smooth up and down swinging of the swing portion 220 and reduces the driving load of the first drive assembly in driving the swing portion 220 up and down.

[0049] Specifically, in this embodiment, Figure 9 As shown, the avoidance gap 230 formed between the extension portion 210 and the flexible arm 222a is a first gap 231. An extension gap 240 extends from the first gap 231 toward one end of the connecting section 221, away from the adjacent extension portion 210. The provision of the extension gap 240 can further reduce the width of the flexible arm 222a. While ensuring the stability of the multiple flexible arms 222a being dispersedly connected between the dominant wind region 223b and the connecting section 221, the width of the main rotation area of the flexible arm 222a can be further reduced. This correspondingly further improves the rotational elastic deformation capacity of the flexible arm 222a, thereby further improving the smoothness of the first drive assembly driving the swing portion 220 to swing up and down.

[0050] In this embodiment, Figure 8 As shown, the connecting section 221 is smoothly connected to the flexible arm 222a, and its thickness gradually increases in the direction away from the flexible arm 222a, thereby ensuring that the flexible arm 222a has a smaller thickness and higher elastic deformation ability. The connecting section 221 can not only achieve a smooth connection with the flexible arm 222a, but also ensure the firmness of the connection with the air outlet grille 100, and accordingly ensure the smoothness of the swinging section 223 swinging around the flexible arm 222a and ensure the firmness of the swinging part 220 connected to the air outlet grille 100.

[0051] Similarly, if Figure 8 As shown, connecting arm 223a smoothly transitions to flexible arm 222a, and its thickness gradually decreases toward flexible arm 222a. The dominant airflow region 223b is thicker to ensure its shape and airflow stability. The provision of connecting arm 223a enables a smooth transition between dominant airflow region 223b and flexible arm 222a, ensuring smooth demolding of swinging portion 220.

[0052] Specifically, the thickness of the flexible arm 222a may be 0.4 mm to 0.6 mm, the thickness of the main wind direction area 223b may be 2 mm to 2.2 mm, and the thickness of the connecting section 221 and the connecting arm 223a may both range from 0.4 mm to 2.2 mm.

[0053] In this embodiment, the ratio of the extended lengths of the connecting section 221, the flexible section 222, and the swinging section 223 in the direction away from the air grille 100 ranges from 1:1.5 to 2.5:9 to 11, preferably 1:2:10. This ensures a secure connection between the connecting section 221 and the air grille 100 and improves the stability of the swinging portion 220 connected to the air grille 100. The flexible section 222 has a high elastic deformation capacity, allowing the swinging section 223 to swing smoothly and reducing the driving load of the first drive assembly. The swinging section 223 also has a large air guide area, thereby improving its air guide effect.

[0054] Optionally, in this embodiment, if Figure 7 As shown, the air outlet device 50 further includes a base 300, which is integrally formed on one side of the air outlet grille 100 in the width direction. As a component of the air duct 11 of the air conditioner, the base 300 is connected to the wall of the air duct 11 near the air duct opening 12. Integrating the base 300, the air outlet grille 100, and the swing vane 200 further improves their ease of processing. During assembly, the air outlet grille 100 and the swing vane 200 can be assembled simultaneously by simply connecting the base 300 to the wall of the air duct 11, thereby improving the ease and efficiency of assembly of the air conditioner. Furthermore, the relative positional accuracy of the base 300, the air outlet grille 100, and the swing vane 200 can be ensured, ensuring that the air outlet grille 100 effectively blocks the air duct 11 and that the swing vane 200 effectively guides the air out of the air duct 11.

[0055] In this embodiment, Figure 9 As shown, the edge of the swinging portion 220 facing the base 300 is defined as the facing edge 224. The facing edge 224 includes a first edge segment 224a, a second edge segment 224b, and a third edge segment 224c, along a direction away from the air outlet grille 100. The second edge segment 224b is parallel to the width of the base 300, and both the first edge segment 224a and the third edge segment 224c are inclined away from the base 300, away from the second edge segment 224b. The facing edge 224 is farther from the base 300 at its distal end than at its midsection, reducing the probability of interference between the swinging portion 220 and the base 300 during its swinging, thereby further ensuring smooth swinging of the swing blade 200.

[0056] Optionally, in this embodiment, the length of the swing portion 220 extending from its flexible section 222 away from the air outlet grille 100 is greater than the distance between two adjacent swing portions 220. When the swing portion 220 is raised or lowered, there is always an overlapping area between two adjacent swing portions 220, which can form an effective air guide channel with a smaller width, thereby improving the air guide effect of the swing portion 220.

[0057] In this embodiment, Figure 7 As shown, the air outlet grille 100 may specifically include a plurality of cross-arranged horizontal grille bars 110 and a plurality of vertical grille bars 120, and the side walls of each vertical grille bar 120 facing and facing away from the base 300 are parallel to the width direction of the base 300, so as to facilitate the overall demolding of the air outlet device 50 and improve the product yield.

[0058] Specifically, in this embodiment, Figure 6 As shown, the air duct 11 is rotatably connected to a plurality of air deflectors 30 located downstream of the air outlet device 50. The air deflectors 30 are spaced apart along the width of the air duct 11, and their rotational axes 31 extend vertically. The housing 10 is provided with a second drive assembly, the drive end of which is connected to each air deflector 30 for driving the air deflectors 30 to rotate. The air deflectors 30 swing left and right to guide air, approximately perpendicular to the swing direction of the swing portion 220. During use, the air outlet direction can be adjusted to different levels by adjusting the swing angle of the swing portion 220 and the rotation angle of the air deflectors 30, thereby improving the air outlet direction adjustment effect of the vertical air conditioner and providing a variety of air guide modes.

[0059] Specifically, in this embodiment, Figure 5 、 Figure 6 and Figure 8 As shown, when an air guide plate 30 is provided, the vertical air conditioner can include a far-throw wind mode. In the far-throw wind mode, each swing part 220 is located in a horizontal position, and the air guiding direction of the air guide plate 30 is perpendicular to the plane where the air duct opening 12 of the air duct 11 is located. When an area of the room, such as a kitchen, which is far away from the floor-standing air conditioner needs to be cooled or heated, the floor-standing air conditioner can be controlled to enter the remote air mode. Specifically, the first drive assembly drives the swing portion 220 to rotate to an approximately horizontal position, and the second drive assembly drives the air guide plate 30 to rotate to an orientation approximately perpendicular to the plane of the air duct opening 12. At this time, the extension portion 210 and the swing portion 220 are in corresponding positions, and the swing blade 200 as a whole extends horizontally to guide the air forward. The airflow blown out through the air duct 11 is approximately parallel to the air guide surface of the swing blade 200 and the air guide surface of the air guide plate 30. Therefore, the swing blade 200 and the air guide plate 30 will not have a deflecting and decelerating effect on the airflow. Accordingly, the airflow can be blown outward to a farther distance under the horizontal guiding air supply effect of the swing blade 200 and the guiding air supply effect of the guide plate, thereby achieving rapid temperature adjustment of a remote area.

[0060] In this embodiment, the vertical air conditioner can also include a long-range and short-range soft mode, such as Figure 1 、 Figure 2 and Figure 4 As shown, in the long-throw, near-soft mode, each swing portion 220 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. The long-throw, near-soft mode is a specific mode of the zero-wind mode. The only difference is that the two airflows guided by the extension portion 210 of the swing blade 200 and the swing portion 220 are broken up and decelerated after collision and flow to the area where the air guide plate 30 is located. Under the guidance of the air guide plate 30, they flow forward, thereby reducing the diffusion of airflow to the left and right sides and concentrating the airflow forward. Accordingly, while ensuring a gentle breeze feeling in the area near the front of the air conditioner, the air flow rate is increased, thereby further improving the temperature regulation efficiency in this area.

[0061] Specifically, in this embodiment, Figure 3 As shown, the extension length of the swing part 220 from its flexible section 222 away from the air outlet grille 100 is L, the distance between two adjacent swing parts 220 is h, and in the long-throw and short-throw soft mode, the upward angle of the swing part 220 is θ, L>h and h-5≤sinθ·L≤h. Among them, the total extension length of the flexible section 222 and the swing section 223 is L, and the extension length L determines the guide length and air supply distance of the swing part 220 for the air outlet of the air duct 11, and the upward angle θ of the swing blade 200 determines the guide direction, air supply distance and air supply height of the swing part 220 for the air outlet of the air duct 11. Within a certain range, the greater the extension length of the swing part 220 and the larger the upward angle θ, the greater its guide length, the greater its air supply distance and the higher its air supply height. The airflow sent through the swing part 220 bypasses the front area of the air conditioner by a greater distance, and the collision intensity of the airflow with the airflow sent through the extension part 210 above it is greater, and the effect of the collision and dispersion of the two airflows is better, thereby further improving the softness of the airflow flowing to the area closer to the front side of the air conditioner; the spacing h between two adjacent swing blades 200 determines the number of swing blades 200 on the air outlet grille 100. The greater the number, the higher the driving load requirement for the first driving component and the smaller the ventilation volume of the air duct 11. 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 driving component. At the same time, in the long-throw and near-soft mode, the area close to the air conditioner can obtain more comfortable air supply and better soft wind effect.

[0062] Specifically, h may be 40 to 50 cm, and L may be 50 to 65 cm.

[0063] In this embodiment, air duct 11 is further equipped with a sweeping assembly and a third drive assembly located upstream of air outlet device 50. The sweeping assembly includes a plurality of sweeping blades spaced vertically apart. 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 guide 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 200. After the primary wind diversion, the airflow then flows to pendulum blade 200, where it undergoes a secondary wind diversion adjustment, thereby improving the airflow diversion effect of the air conditioner on the upward or downward tilt of the air outlet.

[0064] Specifically, in the long-throw and short-throw soft mode, the wind-sweeping blades can be raised by 35° to 55°.

[0065] In this embodiment, Figure 1 and Figure 5 As shown, there can be two air outlet devices 50, which are arranged in sequence along the height direction. Providing two air outlet devices 50 shortens the length of each air outlet device 50, thereby improving processing convenience and mold yield. Specifically, the height of the air duct 11 is approximately 900 cm, and the length of the two air outlet devices 50 is approximately 450 cm.

[0066] Preferably, when the vertical air conditioner is in standby or off mode, the swing angle of the swing portion 220 is equal to its demolding angle. When the air conditioner enters the standby or off mode, the first drive assembly drives the swing portion 220 to swing to the demolding position. At this point, the position of the swing portion 220 relative to the air outlet grille 100 is the same as the relative position of the swing portion 220 and the air outlet grille 100 when the air outlet device 50 was demolded. Therefore, the flexible section 222 does not undergo elastic bending deformation, thereby reducing stress fatigue of the flexible section 222 and correspondingly increasing its service life.
