Description

Technical Field

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

[0002] With the advancement of technology, consumers are increasingly demanding air conditioners, and at the same time, they are also demanding a higher quality experience from their air conditioners. In existing cabinet units, the vertical air guide blades are positioned using a positioning structure located near the middle of the blades in the vertical direction. This creates significant friction between the positioning structure and the supporting ribs, causing unusual noise and vibration during the blades' rotation. This reduces the blades' stability and impacts the user experience. Summary of the Invention

[0003] The problem solved by the present invention is how to improve the problems in the prior art of abnormal noise generated by air guide blades during rotation and low rotation stability of the air guide blades.

[0004] In order to solve the above problems, the present invention provides an air outlet structure applied to an air conditioner, wherein the air outlet structure includes an air outlet frame, air guide blades and a driving device;

[0005] The air outlet frame is provided with an air outlet cavity; and the air outlet frame has a top plate located on the top of the air outlet cavity;

[0006] One end of the air guide blade is suspended on the top plate, and the air guide blade is located inside the air outlet cavity; the end of the air guide blade is rotatably matched with the top plate;

[0007] The driving device is in transmission connection with the air guide blades to drive the air guide blades to rotate relative to the top plate.

[0008] The advantages of the air outlet structure provided by the present invention over the prior art include:

[0009] In this air outlet structure, the air guide blades are rotatably assembled to the top plate by being suspended on the top plate at their ends. The positioning position of the air guide blades can be set at the top, which can prevent the air guide blades from twisting due to installation errors and increasing friction with the top plate. Therefore, the problem of abnormal noise during the rotation of the air guide blades relative to the top plate can be improved. In addition, since the driving device drives the air guide blades to rotate, the force point where the air guide blades are suspended on the top plate and the point where the air guide blades are acted upon by the driving device are both close to the ends of the air guide blades, thereby ensuring the stable rotation of the air guide blades and preventing the air guide blades from shaking. In summary, this air outlet structure can improve the problems of abnormal noise during the rotation of the air guide blades and the low rotation stability of the air guide blades in the prior art.

[0010] In order to realize that the wind guide blade is suspended on the top plate and rotatably cooperates with the top plate, optionally, the wind guide blade includes a blade body, a rotating end and a sliding structure; the rotating end is arranged at the end of the blade body, and the sliding structure is arranged radially outside the rotating end;

[0011] The blade body is located in the air outlet cavity;

[0012] The rotating end passes through the top plate and is rotatably engaged with the top plate;

[0013] The sliding structure is suspended from the top plate, and is configured to slide along a circular path on the top plate when the rotating end rotates relative to the top plate.

[0014] Optionally, the top plate includes a plate body and a bearing structure; the bearing structure is arranged on the plate body, and the bearing structure forms a matching hole; the rotating end is rotatably matched with the matching hole; the sliding structure is slidably connected to the bearing structure.

[0015] Optionally, the rotating end passes through the matching hole, and the sliding structure is slidably matched with a side of the bearing structure away from the air outlet cavity.

[0016] Optionally, the sliding structure includes a slider, which is protruding from the outer side of the rotating end and overlaps the bearing structure to slidably cooperate with the bearing structure.

[0017] In order to ensure the sliding stability of the slider relative to the bearing structure, optionally, a curved mating surface is provided on a side of the slider close to the bearing structure; the curved mating surface abuts against the bearing structure to slidably cooperate with the bearing structure.

[0018] To ensure that the air guide blade can rotate stably relative to the top plate, two sliders are optionally provided on the rotating end, and the two sliders are symmetrically arranged on both sides of the rotating end. The two sliders respectively provide a bearing force to the opposite sides of the rotating end, ensuring that the rotating end is subjected to uniform force, thereby ensuring the rotational stability of the rotating end.

[0019] Optionally, a notch is formed on the supporting structure, the notch being connected to the matching hole; the notch being configured to allow the slider to pass through. The slider can be removed from or inserted into the notch, thereby facilitating the assembly of the air guide blade.

[0020] Optionally, the air outlet structure further includes a cover plate; a limiting structure is provided on the cover plate; the cover plate is detachably connected to the top plate, and the limiting structure extends into the notch. When the limiting structure extends into the notch, the slider is prevented from dislodging from the notch during rotation relative to the supporting structure, thereby improving the stability of the sliding fit between the air guide blade and the top plate.

DETAILED DESCRIPTION

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0039] In one embodiment of the present application, an air conditioner (not shown) is provided that can be installed in a designated space and, when the air conditioner is in operation, can be configured to provide air conditioning to the designated space. Air conditioning functions include, but are not limited to, temperature regulation, humidity regulation, fresh air regulation, wind speed regulation, and removal of airborne particles. It should be noted that the air conditioner can generate airflow when in operation, which is directed by the air conditioner into the designated space and can be configured to provide air conditioning to the designated space.

[0040] In order to facilitate the air conditioner to direct the airflow to a preset location in the designated space, the air conditioner may include an air outlet structure 10. The air outlet structure 10 may be configured to direct the airflow generated by the air conditioner, thereby achieving the purpose of directing the airflow to the preset location in the designated space. Of course, the air conditioner also includes components such as a fan for generating the airflow and an evaporator for processing the airflow, which will not be described in detail here.

[0041] In the embodiments of this application, please refer to Figure 1 and Figure 2 The air outlet structure 10 includes an air outlet frame 100, air guide blades 200, and a drive device (not shown). When the air outlet frame 100 is installed on the air conditioner, the air outlet frame 100 is configured to provide a guiding effect on the airflow so as to guide the airflow generated by the air conditioner to a designated space. In addition, the air guide blades 200 are rotatably arranged on the air outlet frame 100, and the air guide blades 200 can rotate on the air outlet frame 100 to provide a flow direction adjustment effect on the airflow guided by the air outlet frame 100 so that the airflow can be directed to a preset position. The drive device is configured to be in transmission connection with the air guide blades 200 to provide power for the rotation of the air guide blades 200.

[0042] In the prior art, the middle portion of the air guide blade 200 is rotatably connected to the air outlet frame 100 via a positioning structure on the air outlet frame 100, and then a driving device is drivingly connected to the end portion of the air guide blade 200. However, due to installation errors of the air guide blade 200, the coaxiality between the rotation axis of the middle portion of the air guide blade 200 and the positioning structure may be low. As a result, when the driving device drives the air guide blade 200 to rotate, the friction between the air guide blade 200 and the positioning structure increases, causing the air guide blade 200 to twist, resulting in abnormal noise between the air guide blade 200 and the positioning structure, and also causing the air guide blade 200 to shake during rotation, resulting in unstable rotation of the air guide blade 200.

[0043] In order to improve the above technical problems, in other words, to improve the problem in the prior art that the air guide blade 200 produces abnormal noise during rotation and the air guide blade 200 has low rotation stability, an air outlet structure 10 in an embodiment of the present application and an air conditioner using the air outlet structure 10 are provided.

[0044] Among them, in the air outlet structure 10 provided in the present application, an air outlet cavity 101 is provided on the air outlet frame 100, and the air outlet cavity 101 is configured to allow air flow to be discharged, so as to discharge the air flow into the interior of a designated space. In addition, the air outlet frame 100 has a top plate 110 located at the top of the air outlet cavity 101; it should be noted that the top of the air outlet cavity 101 refers to the top of the air outlet cavity 101 corresponding to the top position of the air outlet frame 100 when the air conditioner is normally placed. In other words, the side plate located at the top of the air outlet frame 100 for enclosing the air outlet cavity 101 is the top plate 110. One end of the air guide blade 200 is suspended on the top plate 110, so that the air guide blade 200 is located inside the air outlet cavity 101; and the end of the air guide blade 200 is rotatably matched with the top plate 110. In addition, the driving device is transmission-connected to the end of the air guide blade 200 to drive the air guide blade 200 to rotate relative to the top plate 110.

[0045] As described above, the air guide blade 200 is rotatably assembled with the top plate 110 by being suspended at its end. The positioning position of the air guide blade 200 can be set at the top, which can prevent the air guide blade 200 from twisting due to installation errors of the air guide blade 200 and increasing friction with the top plate 110. Therefore, the problem of abnormal noise generated during the rotation of the air guide blade 200 relative to the top plate 110 can be improved. In addition, since the driving device drives the air guide blade 200 to rotate, the force point where the air guide blade 200 is suspended on the top plate 110 and the point where the air guide blade 200 is acted upon by the driving device are both close to the end of the air guide blade 200, thereby ensuring that the air guide blade 200 rotates stably and preventing the air guide blade 200 from shaking. In summary, the air outlet structure 10 can improve the problems of abnormal noise generated during the rotation of the air guide blade 200 and the low rotation stability of the air guide blade 200 in the prior art.

[0046] It should be noted that the suspension connection of the air guide blade 200 to the top plate 110 can be considered as: the end of the air guide blade 200 is movably connected to the top plate 110. Specifically, the top plate 110 can provide a vertical limiting function for the air guide blade 200, at least to prevent the air guide blade 200 from separating from the top plate 110 along its gravity direction. In other words, when the air conditioner is normally placed, the top plate 110 can at least provide a downward limiting function for the air guide blade 200, thereby limiting the air guide blade 200 from moving downward and separating from the top plate 110; optionally, in other embodiments, the top plate 110 can also provide an upward limiting function for the air guide blade 200, thereby limiting the air guide blade 200 from moving upward and separating from the top plate 110; of course, it can also be considered that the top plate 110 can prevent the air guide blade 200 from moving up and down, thereby ensuring the assembly stability of the air guide blade 200. In addition, the movable connection between the air guide blade 200 and the top plate 110 can realize the rotation of the air guide blade 200 relative to the top plate 110, wherein the rotation center axis of the air guide blade 200 is the vertical axis, so that the air guide blade 200 can swing left and right in the air outlet cavity 101 to facilitate providing flow direction regulation to the airflow.

[0047] Alternatively, in the embodiments of this application, please refer to Figure 3 The air guide blade 200 includes a blade body 230, a rotating end 210, and a sliding structure 220. The rotating end 210 is disposed at the end of the blade body 230. To facilitate rotation of the rotating end 210 relative to the top plate 110, the rotating end 210 is cylindrical. Of course, in other embodiments, the rotating end 210 may also be configured in other shapes as long as it can ensure rotation of the rotating end 210 relative to the top plate 110. In addition, the sliding structure 220 is disposed radially outward of the rotating end 210. When the air guide blade 200 is assembled with the air outlet frame 100, the blade body 230 is located in the air outlet cavity 101. The rotating end 210 passes through the top plate 110 and is rotatably engaged with the top plate 110. The sliding structure 220 is suspended from the top plate 110 and is configured to slide along a circular path on the top plate 110 when the rotating end 210 rotates relative to the top plate 110. The cooperation between the sliding structure 220 and the top plate 110 can provide a downward limiting effect on the air guide blade 200; of course, in other embodiments, the cooperation between the sliding structure 220 and the top plate 110 can also provide an upward limiting effect on the air guide blade 200.

[0048] It should be noted that during the rotation of the air guide blade 200 relative to the top plate 110, the rotating end 210 rotates relative to the top plate 110 to realize the rotation of the blade body 230. At the same time, the rotating end 210 drives the sliding structure 220 to slide on the top plate 110. Since the rotating end 210 moves relative to the top plate 110 by self-rotation, the sliding structure 220 moves relative to the top plate 110 by sliding along a circular path.

[0049] Furthermore, a transmission hole 211 is defined at the end of the rotating end 210 distal from the blade body 230. The output shaft of the driving device engages with the transmission hole 211, thereby facilitating the driving device's rotation of the rotating end 210 and thereby achieving rotation of the air guide blade 200. Optionally, the transmission hole 211 is prismatic in shape, thereby facilitating the transmission engagement between the output shaft of the driving device and the rotating end 210. Of course, in other embodiments, the transmission hole 211 may also be configured as a hole of other shapes, such as an elliptical hole or a special-shaped hole. Alternatively, a keyway may be provided in the circumferential wall of a cylindrical hole to form the transmission hole 211.

[0050] To facilitate cooperation with the sliding structure 220, in some embodiments of the present application, the top plate 110 optionally includes a plate body 112 and a supporting structure 111. The supporting structure 111 is disposed on the plate body 112 and defines a mating hole 1111. The rotating end 210 rotatably engages with the mating hole 1111. The sliding structure 220 is slidably connected to the supporting structure 111. In other words, the supporting structure 111 can provide a downward limiting effect on the sliding structure 220, thereby providing a downward limiting effect on the wind guide blade 200. The supporting structure 111 defining the mating hole 1111 can also be considered as forming the mating hole 1111 in the middle of the supporting structure 111. When the rotating end 210 and the mating hole 1111 engage with each other, the sliding structure 220 disposed outside the rotating end 210 can be conveniently slidably engaged with the supporting structure 111.

[0051] It should be noted that the bearing structure 111 can be a part of the plate body 112. In other words, a mating hole 1111 can be provided on the plate body 112, and the rotating end 210 can be rotatably mated with the mating hole 1111. In this case, the portion of the plate body 112 that is slidably mated with the sliding structure 220 can be considered the bearing structure 111. Of course, as in some embodiments of the present application, the bearing structure 111 can also be a structure that is provided for the sliding structure 220 and is adapted to the sliding structure 220. Of course, even if the bearing structure 111 is a structure provided for the sliding structure 220, the bearing structure 111 can also be formed integrally with the plate body 112; of course, the bearing structure 111 can also be connected to the plate body 112 by welding, clamping, or bonding.

[0052] Alternatively, in some embodiments of the present application, the outer side of the rotating end 210 is disposed in contact with the peripheral wall of the mating hole 1111. In other words, during the rotation of the rotating end 210 relative to the top plate 110, the outer side of the rotating end 210 slides relative to the inner peripheral wall of the mating hole 1111. Thus, the mating hole 1111 provides a limiting effect on the rotating end 210, preventing radial movement of the rotating end 210 relative to the top plate 110 while ensuring stable engagement between the sliding structure 220 and the supporting structure 111. It should be understood that in other embodiments of the present application, even if a certain gap is formed between the inner peripheral wall of the mating hole 1111 and the outer side of the rotating end 210, this can still be considered as a rotational engagement between the rotating end 210 and the mating hole 1111. In this case, the radial movement of the rotating end 210 can be limited by the transmission engagement between the drive device and the air guide vane 200, thereby also ensuring stable engagement between the sliding structure 220 and the supporting structure 111.

[0053] The rotating end 210 passes through the mating hole 1111, and the sliding structure 220 slidably engages with the side of the supporting structure 111 away from the air outlet cavity 101. It should be noted that the air guide blade 200 tends to move toward the air outlet cavity 101 under the action of its gravity. By supporting the sliding structure 220 on the supporting structure 111, the supporting structure 111 restricts the sliding structure 220 from moving toward the air outlet cavity 101, thereby providing a downward limit for the air guide blade 200 and ensuring that the air guide blade 200 is stably assembled on the top plate 110. In addition, because the sliding structure 220 can slide on the supporting structure 111, the air guide blade 200 can be suspended on the top plate 110 while being able to rotate relative to the top plate 110.

[0054] It should be understood that in other embodiments of the present application, the sliding structure 220 and the supporting structure 111 may be arranged in other ways. For example, the sliding structure 220 may be a sliding groove provided on the radially outer circumference of the rotating end 210, and the supporting structure 111 may extend into the sliding groove and slide in cooperation with the sliding groove. In this case, the sliding groove and the walls on both sides of the sliding groove can be regarded as the sliding structure 220. In this case, the cooperation between the supporting structure 111 and the walls on both sides of the sliding groove can provide an upward and downward limiting effect on the air guide blade 200. For another example, a sliding rail may be provided on the side of the supporting structure 111 near the air outlet chamber 101, and the sliding structure 220 slides in cooperation with the sliding rail. The sliding rail may be arranged in a circular shape, thereby allowing the sliding structure 220 to perform a circular motion relative to the supporting structure 111. In this case, the sliding rail can provide a downward limiting effect on the sliding structure 220, while the supporting structure 111 can also provide an upward limiting effect on the sliding structure 220. For example, a sliding groove is opened on the inner wall of the matching hole 1111, and the sliding structure 220 extends into the sliding groove and slides with the sliding groove. At this time, the two side walls of the sliding groove provide a limiting effect to the sliding structure 220, so that the supporting structure 111 provides an upward limiting effect and a downward limiting effect to the sliding structure 220.

[0055] In addition, in other embodiments of the present application, the rotating end 210 may not pass through the matching hole 1111. For example, the sliding structure 220 slides with the supporting structure 111 via a slide rail provided on the inner side of the supporting structure 111 near the air outlet cavity 101, and the output shaft of the driving device passes through the matching hole 1111 and is transmission-connected to the rotating end 210. In this case, the output shaft of the driving device rotates in engagement with the matching hole 1111. Of course, this can also be regarded as the rotating end 210 rotating in engagement with the matching hole 1111.

[0056] Optionally, to facilitate the sliding cooperation between the sliding structure 220 and the supporting structure 111, in some embodiments of the present application, the sliding structure 220 includes a slider 221, which is protruding from the outside of the rotating end 210 and overlaps the supporting structure 111 to slidably cooperate with the supporting structure 111. The slider 221 overlapping the supporting structure 111 refers to the slider 221 being placed on the side of the supporting structure 111 away from the air outlet cavity 101. In this case, the supporting structure 111 provides an upward bearing force to the slider 221. At the same time, the slider 221 can overcome the friction between the slider 221 and the supporting structure 111 and slide relative to the supporting structure 111.

[0057] Of course, in other embodiments of the present application, the sliding structure 220 may also be arranged in other ways to achieve sliding cooperation with the supporting structure 111. For example, the sliding structure 220 includes a connecting rod and a pulley, one end of the connecting rod is connected to the radially outer side of the rotating end 210, and the pulley is arranged at the other end of the connecting rod. The sliding cooperation between the sliding structure 220 and the supporting structure 111 can be achieved through the rolling cooperation between the pulley and the supporting structure 111.

[0058] In addition, in some embodiments of the present application, the slider 221 can be regarded as a block-shaped structure protruding from the radially outer side of the rotating end 210 along a straight line. In this case, the slider 221 contacts and cooperates with the supporting structure 111 near the side of the supporting structure 111, thereby achieving the purpose of the slider 221 overlapping the supporting structure 111, and at the same time, achieving sliding cooperation between the slider 221 and the supporting structure 111. It should be understood that in other embodiments of the present application, the slider 221 can also be arranged in other ways, for example, the slider 221 is in an inverted L-shape. In other words, the slider 221 includes a first connecting portion and a second connecting portion arranged at an angle, one end of the first connecting portion is connected to the rotating end 210 and is approximately perpendicular to the axis of the rotating end 210; the second connecting portion is connected to the other end of the first connecting portion. Based on this, a slide rail can be provided on the side of the supporting structure 111 away from the air outlet chamber 101, and the sliding cooperation between the second connecting portion and the slide rail can achieve sliding cooperation between the sliding structure 220 and the supporting structure 111.

[0059] Optionally, in some embodiments of the present application, the sliding fit of the sliding structure 220 and the bearing structure 111 is achieved by the block-shaped slider 221 and the bearing structure 111 being in contact with each other in a plane away from the air outlet cavity 101. In this case, the bearing structure 111 can also be regarded as a plate-shaped, and the slider 221 is in sliding fit with the plate-shaped bearing structure 111. It is understandable that in other embodiments of the present application, the sliding structure 220 can also be set to a plate-shaped, and the bearing structure 111 can be set to a block-shaped. In this case, the sliding fit can also be achieved by the block-shaped bearing structure 111 and the plate-shaped sliding structure 220, and the sliding structure 220 can also be overlapped on the bearing structure 111. Alternatively, in other embodiments of the present application, the sliding structure 220 and the bearing structure 111 can also be set to a plate-shaped. In this case, the sliding fit of the bearing structure 111 and the sliding structure 220 can be achieved by the surface-to-surface contact between the bearing structure 111 and the sliding structure 220.

[0060] Optionally, to ensure that the slider 221 and the supporting structure 111 are stable while ensuring that the slider 221 can slide easily relative to the supporting structure 111, a curved mating surface 2211 is optionally provided on the side of the slider 221 adjacent to the supporting structure 111; the curved mating surface 2211 abuts against the supporting structure 111 to slidably engage with the supporting structure 111. It should be noted that the curved mating surface 2211 is a cylindrical curved surface. In other words, the curved mating surface 2211 can be considered as a portion of the radial outer circumference of the cylinder; of course, when the slider 221 is cylindrical, the curved mating surface 2211 can also be considered as the complete curved surface on the outer side of the cylindrical structure. Therefore, when the arc-shaped mating surface 2211 is mated with the supporting structure 111, the arc-shaped mating surface 2211 and the supporting structure 111 are in line contact, which not only improves the mating stability between the slider 221 and the supporting structure 111, but also reduces the friction between the slider 221 and the supporting structure 111, thereby facilitating the sliding mating of the sliding structure 220 and the supporting structure 111.

[0061] It should be understood that in other embodiments of the present application, the arcuate mating surface 2211 can also be configured as a spherical surface. In this case, the arcuate mating surface 2211 and the supporting structure 111 are in point contact. On this basis, multiple spherical structures can be provided on the slider 221, thereby achieving a sliding fit between the slider 221 and the supporting structure 111 through multi-point contact. Of course, in other embodiments, the slider 221 can also achieve a sliding fit with the supporting structure 111 through surface contact with the supporting structure 111. In other words, the side of the slider 221 that mates with the supporting structure 111 is a flat surface.

[0062] Optionally, see Figure 4 To improve the rotational stability of the rotating end 210, in some embodiments of the present application, two sliders 221 are provided on the rotating end 210, and the two sliders 221 are symmetrically arranged on both sides of the rotating end 210. The two symmetrically arranged sliders 221 can provide support to the rotating end 210 from opposite sides of the rotating end 210, thereby ensuring that the rotating end 210 is evenly stressed during its rotation, thereby ensuring the stability of the rotating end 210 and preventing the rotating end 210 from shaking during rotation.

[0063] It should be understood that in other embodiments of the present application, the number of sliders 221 can also be set to other numbers. For example, the sliders 221 are set to multiple, in other words, the number of sliders 221 is three or more. At this time, the multiple sliders 221 can provide bearing force to the rotating end 210 from multiple positions of the rotating end 210 through multi-point contact with the bearing structure 111, and can also ensure the rotation stability of the rotating end 210. Among them, when the number of sliders 221 is multiple, the arc between any two adjacent sliders 221 does not exceed 180°. At this time, there are two situations: First, if Figure 5 , wherein two sliders 221 are symmetrically arranged on opposite sides of the rotating end 210, and at the same time, two intervals of 180° arc are formed between the two sliders 221, and the remaining sliders 221 are arranged in one of the intervals; secondly, as Figure 6 The arc between any two adjacent sliders 221 is less than 180°, so that a slider 221 is provided on both sides of a straight line along any diameter of the rotating end 210. Optionally, when there are three or more sliders 221, the sliders 221 may be evenly spaced and distributed outside the rotating end 210. Figure 5 and Figure 6 The dashed line represents the diameter of the rotating end 210. For another example, the number of sliders 221 can be set to one. In this case, the sliding fit between the air guide blade 200 and the top plate 110 can be achieved through the sliding fit between the slider 221 and the supporting structure 111. Furthermore, to ensure the stability of the rotating end 210, the fitting stability between the rotating end 210 and the top plate 110 can be improved by fitting the rotating end 210 against the inner circumferential wall of the fitting hole 1111.

[0064] In addition, please refer to Figure 7 and Figure 8 In some embodiments of the present application, a notch 1112 is provided on the supporting structure 111, and the notch 1112 is connected to the matching hole 1111; the notch 1112 is configured to allow the slider 221 to pass through. The supporting structure 111 can be regarded as a ring extending along a circular path. In this case, the supporting structure 111 is surrounded by a circular matching hole 1111 to facilitate the matching of the matching hole 1111 with the rotating end 210. In addition, a notch 1112 is provided on the supporting structure 111 so that the notch 1112 is connected to the matching hole 1111 along the radial direction of the matching hole 1111. The slider 221 can pass through the notch 1112 to facilitate the slider 221 to bypass the supporting structure 111, thereby facilitating the sliding matching of the slider 221 with the side of the supporting structure 111 away from the air outlet cavity 101.

[0065] It should be noted that in some embodiments of the present application, the notch 1112 may penetrate the supporting structure 111 along the radial direction of the supporting structure 111 to provide sufficient space for the slider 221 to pass through the notch 1112. Of course, in other embodiments of the present application, the notch 1112 may not penetrate the supporting structure 111. In other words, the notch 1112 may be a groove formed on the peripheral wall of the mating hole 1111.

[0066] In addition, corresponding to the two sliders 221 in the embodiment of the present application, two symmetrically arranged notches 1112 are provided on the supporting structure 111, so that the two sliders 221 can pass through the two notches 1112 simultaneously, thereby facilitating the two sliders 221 to simultaneously bypass the supporting structure 111 and slide with the side of the supporting structure 111 away from the air outlet cavity 101. Of course, if there are multiple sliders 221, multiple notches 1112 can also be provided to correspond to the multiple sliders 221. It should be understood that in other embodiments, if there is only one slider 221, two notches 1112 can also be provided to facilitate the easy disassembly of the air guide blade 200 in any situation.

[0067] In other embodiments of the present application, when the sliding structure 220 is plate-shaped and the supporting structure 111 is block-shaped, the sliding structure 220 can be set to be annular, and a gap 1112 can be opened on the sliding structure 220 to facilitate the sliding structure 220 to bypass the supporting structure 111 and thus overlap on the side of the supporting structure 111 away from the air outlet cavity 101.

[0068] It is worth noting that, in some embodiments of the present application, in order to ensure that the slider 221 slides stably on the supporting structure 111, and in order to provide the slider 221 with a longer sliding stroke to facilitate the control of the air guide blade 200 to rotate at a large angle, the number of notches 1112 is set to two, thereby allowing the slider 221 to slide arbitrarily on the supporting structure 111 between the two notches 1112, thereby avoiding the problem of the slider 221 easily falling out of the notch 1112. Of course, on this basis, the control stroke of the driving device can be set so that the position of the slider 221 driven by the driving device is located between the two notches 1112, thereby ensuring that the slider 221 is stably slidingly engaged with the supporting structure 111 through the driving device.

[0069] Also, see Figure 9In an embodiment of the present application, the air outlet structure 10 further includes a cover plate 300; a limiting structure 310 is provided on the cover plate 300; the cover plate 300 is detachably connected to the top plate 110, and the limiting structure 310 extends into the interior of the notch 1112. The cover plate 300 can provide a bearing function for the limiting structure 310. When the cover plate 300 is detachably connected to the top plate 110, the stability of the limiting structure 310 relative to the plate body 112 can be ensured. Thus, when the limiting structure 310 extends into the interior of the notch 1112, the slider 221 can be effectively prevented from falling out of the notch 1112. The limiting structure 310 can be columnar, and the cross-section of the limiting structure 310 is the same shape as the notch 1112, so as to facilitate the cooperation between the limiting structure 310 and the notch 1112. Of course, in other embodiments, when the limiting structure 310 extends into the notch 1112, the limiting structure 310 may also form a gap with the inner side of the notch 1112. In other words, the cross-sectional area of ​​the limiting structure 310 is smaller than the opening area of ​​the notch 1112, thereby facilitating the limiting structure 310 to penetrate into the notch 1112.

[0070] It should be noted that, when the limiting structure 310 penetrates into the notch 1112 , the limiting structure 310 can also provide a limiting function for the slider 221 to limit the sliding stroke of the slider 221 .

[0071] In addition, the plate body 112 is provided with an assembly hole 1122; the supporting structure 111 is provided on the inner peripheral wall of the assembly hole 1122. Specifically, a cylindrical mounting structure 1121 is provided on the plate body 112, and the assembly hole 1122 is provided inside the mounting structure 1121, and the axis of the assembly hole 1122 coincides with the axis of the mounting structure 1121. By arranging the supporting structure 111 within the inner peripheral wall of the assembly hole 1122, a space for the sliding block 221 to slide is formed between the side of the supporting structure 111 away from the air outlet cavity 101 and the inner peripheral wall of the assembly hole 1122. In this case, the peripheral wall of the assembly hole 1122 can provide protection for the sliding block 221, while also ensuring that the sliding block 221 is not affected by other parts, thereby ensuring a stable sliding fit between the sliding block 221 and the supporting structure 111. At the same time, when a gap is formed between the outer side of the rotating end 210 and the peripheral wall of the matching hole 1111, the rotating end 210 can be prevented from moving in its radial direction by the peripheral wall of the assembly hole 1122 and the slider 221, thereby ensuring the stability of the matching between the air guide blade 200 and the top plate 110.

[0072] In summary, in the air outlet structure 10 and air conditioner provided in the embodiment of the present application, the air guide blade 200 is rotatably assembled with the top plate 110 by being suspended at its end. The air guide blade 200 can be positioned at the top, which can prevent the air guide blade 200 from twisting due to installation errors, thereby preventing the friction between the air guide blade 200 and the top plate 110 from increasing. Therefore, the problem of abnormal noise generated during the rotation of the air guide blade 200 relative to the top plate 110 can be improved. In addition, because the driving device drives the air guide blade 200 to rotate, the force point where the air guide blade 200 is suspended on the top plate 110 and the point where the air guide blade 200 is acted upon by the driving device are both close to the end of the air guide blade 200, thereby ensuring that the air guide blade 200 rotates stably and preventing the air guide blade 200 from shaking. In summary, the air outlet structure 10 can improve the problems of abnormal noise generated during the rotation of the air guide blade 200 and the low rotation stability of the air guide blade 200 in the prior art. The provision of the notch 1112 on the supporting structure 111 facilitates assembly and disassembly of the air guide blade 200 and the top plate 110, thereby improving the efficiency of assembly and disassembly of the air guide blade 200. Furthermore, the provision of the limiting structure 310 prevents the slider 221 from falling out of the notch 1112, thereby improving the sliding fit stability between the slider 221 and the supporting structure 111, and thus improving the sliding fit stability between the air guide blade 200 and the top plate 110.
