Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to an indoor air conditioning unit. Background Technology

[0002] With the development of science and technology, the number of air conditioners is constantly increasing, and their functions are becoming more and more diverse. In particular, as people's living standards continue to improve, users are increasingly demanding higher levels of comfort from air conditioners. For example, features such as the anti-direct-blow function and the wide-range airflow function of air conditioners require the air deflector to function effectively.

[0003] Currently, in existing technologies, whether it's a wall-mounted, ceiling-mounted, or floor-standing air conditioner indoor unit, the air guide vane is relatively fixed at the air outlet. The direction or angle of the airflow is adjusted by configuring the rotation angle of the vane. This means the relative distance between the vane and the air outlet cannot be adjusted, limiting the diversification of air conditioning air delivery modes and preventing air conditioners from further meeting users' needs for air delivery comfort or diverse air delivery modes. Utility Model Content

[0004] One objective of this invention is to provide an air conditioning indoor unit that can overcome at least one technical defect in the prior art.

[0005] A further objective of this invention is to diversify the air supply modes of the indoor unit of the air conditioner, thereby further meeting users' needs for air supply comfort or variety of air supply modes.

[0006] Specifically, this utility model provides an indoor unit for an air conditioner, comprising:

An output hole is located at the front of the box, corresponding to the mounting hole of the driven wheel. One end of the guide plate drive shaft passes through the output hole and connects to the mounting hole of the driven wheel, while the other end of the drive plate drive shaft is connected to the air guide plate.

[0023] Furthermore, the indoor unit of the air conditioner also includes:

[0024] A telescopic limiting cover is installed on the housing adjacent to the air outlet, and its front end is provided with a telescopic opening for allowing the telescopic transmission box to telescopically move. The telescopic transmission box is telescopically installed inside the telescopic limiting cover in the front-back direction. The telescopic limiting cover is used to limit the telescopic movement of the telescopic transmission box in the front-back direction.

[0025] Furthermore, a clearance sliding hole extending in the front-to-back direction is provided on one side of the telescopic limiting cover corresponding to the input hole. The rotation drive motor is located outside the telescopic limiting cover, and the output shaft of the rotation drive motor passes through the clearance sliding hole and is installed inside the input hole. The clearance sliding hole is used to allow the output shaft of the rotation drive motor to slide inside it as the telescopic transmission component moves.

[0026] Furthermore, a telescopic rack is provided on one side of the exterior of the telescopic transmission box, arranged along the direction of extension and retraction of the telescopic transmission component; and,

[0027] The indoor unit of the air conditioner also includes:

[0028] A telescopic drive motor is mounted on the housing, and a telescopic drive gear is mounted on its output shaft. The telescopic drive gear meshes with the telescopic rack to drive the telescopic transmission component to perform telescopic movement.

[0029] Furthermore, the housing includes one or more supports disposed at the air outlet, each support having a telescopic cavity extending in the front-rear direction and opening forward; the telescopic cavities and telescopic limiting covers are correspondingly disposed in the lateral direction; and,

[0030] A telescopic transmission gear meshes between the telescopic drive gear and the telescopic rack; and...

[0031] The indoor unit of an air conditioner also includes:

[0032] The driven telescopic component is telescopically installed in the telescopic cavity and is positioned laterally corresponding to the telescopic transmission box. It is equipped with a driven rack arranged in the front-back direction. The telescopic rack and the driven rack are located on the same side in the vertical direction of the telescopic transmission box and the driven telescopic component, respectively. The air guide plate is rotatably connected to the front end of the driven telescopic component.

[0033] The telescopic link is arranged horizontally, and a telescopic driven gear is sleeved on it at the position corresponding to the driven rack. The telescopic driven gear is meshed with the driven rack, and the telescopic transmission gear is sleeved on the telescopic link. The telescopic link is used to drive the driven telescopic component to perform synchronous telescopic movement when the telescopic transmission box moves in the front-back direction.

[0034] Furthermore, an air outlet duct is provided inside the casing, connecting to the air outlet; and,

[0035] The housing contains an installation space separated from the outlet air duct by an air duct isolation cover. The installation space is located at the left and right ends of the outlet air duct. The telescopic transmission component and the telescopic drive motor are both housed within this installation space. The air duct isolation cover includes an isolation plate between the outlet air duct and the installation space, and a telescopic plate connected to the isolation plate. The telescopic plate is located in front of the installation space, and an opening is provided on the telescopic plate corresponding to the telescopic opening.

[0037] Furthermore, the air guide plate is provided with a drive support plate extending in the front-to-back direction, and the drive support plate is provided with a drive hole extending in the lateral direction.

[0038] The guide plate drive shaft is connected to the drive hole. The cross-section of the guide plate drive shaft is polygonal, and the cross-section of the guide plate drive shaft has the same shape as the drive hole.

[0039] This utility model's indoor air conditioner unit, equipped with a telescopic transmission component, a rotary drive component, and a rotary transmission mechanism, allows the air guide plate to move telescopically relative to the air outlet in the front-to-back direction. Simultaneously, the rotary transmission mechanism transmits power from the rotary drive component to the air guide plate, enabling adjustable distance between the air guide plate and the air outlet while also allowing lateral rotation. Thus, this utility model's indoor air conditioner unit overcomes the limitation of the inability to adjust the relative distance between the air guide plate and the air outlet. Therefore, this utility model's indoor air conditioner unit allows for more diverse airflow modes, further meeting users' needs for airflow comfort or diverse airflow modes.

[0040] Furthermore, in the indoor unit of this utility model, since the rotating drive component is located at the rear of the telescopic transmission component and drives the air guide plate to rotate through the rotating transmission component, the weight of the rotating drive component can be minimized and applied to the front end of the telescopic transmission component. This improves the flexibility of the air guide plate in moving and rotating relative to the air outlet. At the same time, it effectively alleviates the limitations on the movement and rotation of the air guide plate relative to the air outlet caused by the rotating drive component being located at the front of the telescopic transmission component and on the guide plate drive shaft. This further enhances the diversity of air supply modes of the indoor unit and better meets users' needs for air supply comfort or diverse air supply modes.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0057] The following is combined with Figures 1 to 8 The indoor unit of the air conditioner in this embodiment will be described in detail below.

[0058] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the indoor unit of the air conditioner may include a housing 100, an air guide plate 200, a telescopic transmission component 300, a guide plate drive shaft 400, a rotation drive component 500, and a rotation transmission mechanism 600.

[0059] An air outlet 110 extending laterally is provided on the front side of the housing 100.

[0060] The air guide plate 200 is located at the air outlet 110.

[0061] The telescopic transmission component 300 is telescopically mounted at the air outlet 110 in the front-to-back direction.

[0062] The guide plate drive shaft 400 is located at the front of the telescopic transmission member 300. The guide plate drive shaft 400 is driven and connected to the air guide plate 200. The guide plate drive shaft 400 is used to extend the air guide plate 200 out of the outside of the air outlet 110 or retract it to the air outlet 110 as the telescopic transmission member 300 extends and retracts (e.g., ...). Figure 4 and Figure 5 As shown, Figure 4 This shows the air guide plate extending from the air outlet. Figure 5 The image shows the air guide plate retracted to the air outlet, and the air guide plate drive shaft 400 is arranged laterally. The air guide plate drive shaft 400 is used to drive the air guide plate 200 to rotate around it.

[0063] The rotation drive 500 is located at the rear of the telescopic transmission 300.

[0064] The rotary transmission mechanism 600 is arranged on the telescopic transmission member 300, and the rotary transmission mechanism 600 is connected between the output end of the rotary drive member 500 and the guide plate drive shaft 400. The rotary transmission mechanism 600 is used to transmit the power of the rotary drive member 500 to the guide plate drive shaft 400.

[0065] Because the indoor unit of this embodiment is equipped with a telescopic transmission component 300, a rotation drive component 500, and a rotation transmission mechanism 600, the air guide plate 200 can be telescopically moved relative to the air outlet 110 in the front-to-back direction. Simultaneously, the rotation transmission mechanism 600 can transmit the power of the rotation drive component 500 to the air guide plate 200, allowing the distance between the air guide plate 200 and the air outlet 110 to be adjustable while also enabling lateral rotation. Therefore, the indoor unit of this embodiment overcomes the limitation that the relative distance between the air guide plate 200 and the air outlet 110 cannot be adjusted. Thus, the indoor unit of this embodiment allows for more diverse air supply modes, further meeting users' needs for air supply comfort or diverse air supply modes.

[0066] It is important to understand that if the rotary drive component 500 is directly positioned at the front end of the telescopic transmission component 300, and the output shaft of the rotary drive component 500 is connected to the guide plate drive shaft 400, the weight of the rotary drive component 500 will be applied to the front end of the telescopic transmission component 300, resulting in greater resistance to the telescopic movement of the telescopic transmission component 300. Furthermore, if the weight at the front end of the telescopic transmission component 300 is too great, the stability of both the telescopic transmission component 300 and the air guide plate 200 will decrease when the telescopic transmission component 300 is extended (for example, the telescopic transmission component 300 and the air guide plate 200 may vibrate). This will reduce the flexibility of the air guide plate 200 in moving and rotating relative to the air outlet 110, and will also limit the distance the air guide plate 200 can move relative to the air outlet 110 and the rotation angle of the air guide plate 200.

[0067] Therefore, in this embodiment of the air conditioner indoor unit, since the rotation drive 500 is located at the rear of the telescopic transmission member 300 and drives the air guide plate 200 to rotate via the rotation transmission member 630, the weight of the rotation drive 500 can be minimized on the front end of the telescopic transmission member 300. This improves the flexibility of the air guide plate 200 in moving and rotating relative to the air outlet 110. At the same time, it effectively alleviates the limitations imposed on the air guide plate 200 in moving and rotating relative to the air outlet 110 when the rotation drive 500 is located at the front of the telescopic transmission member 300 and on the guide plate drive shaft 400. This further enhances the diversity of the air supply modes of the air conditioner indoor unit and better meets the user's needs for air supply comfort or diverse air supply modes.

[0068] Reference Figure 3 In this embodiment, the rotation drive 500 may include a rotation drive motor 510, the output end of which is the output shaft of the drive motor.

[0069] Reference Figure 3 In this embodiment, the rotation transmission mechanism 600 may include a driving wheel 610, a driven wheel 620, and a rotation transmission member 630.

[0070] The drive wheel 610 is mounted on the output shaft of the rotation drive motor 510.

[0071] The driven wheel 620 is rotatably mounted at the front of the telescopic transmission member 300, and the guide plate drive shaft 400 is connected to the mounting hole of the driven wheel 620.

[0072] The rotational transmission component 630 is connected between the driving wheel 610 and the driven wheel, and is used to transmit the power of the driving wheel 610 to the driven wheel.

[0073] It is understood that the above-mentioned limitations of the driving wheel 610, the driven wheel 620, and the rotation transmission member 630 in this embodiment can enable the rotation transmission mechanism 600 to transmit the power of the rotation driving member 500 to the guide plate drive shaft 400, thereby achieving the diversification of the air supply mode of the air conditioning indoor unit.

[0074] Reference Figure 3 In this embodiment, the driving wheel 610 can be a driving gear 611, and the driven wheel 620 can be a driven gear 621. The guide plate drive shaft 400 passes through the mounting hole of the driven gear 621. Furthermore,

[0075] The rotational transmission component 630 may include one or more rotational transmission gears 631 that mesh sequentially.

[0076] One or more sequentially meshing rotary transmission gears 631 are engaged between the driving gear 611 and the driven gear 621.

[0077] It is understandable that the driving wheel 610 can be the driving gear 611, the driven wheel 620 can be the driven gear 621, and the rotation transmission component 630 can be one or more sequentially meshing rotation transmission gears 631 to transmit the power of the rotation driving component 500 to the guide plate drive shaft 400, thereby realizing the diversification of the air supply mode of the air conditioning indoor unit.

[0078] In an alternative embodiment, the driving pulley 610 can be a driving pulley, the driven pulley 620 can be a driven pulley, and the guide plate drive shaft 400 passes through the mounting hole of the driven pulley. Furthermore,

[0079] The rotational transmission component 630 may include a transmission belt fitted on the driving pulley and the driven pulley 620.

[0080] It is understandable that by setting the driving pulley 610 as a driving pulley and the driven pulley 620 as a driven pulley, and by configuring the rotation transmission component 630 as a transmission belt sleeved on the driving pulley and the driven pulley 620, the power of the rotation drive component 500 can be transmitted to the guide plate drive shaft 400, thereby achieving a diversification of the air supply modes of the air conditioning indoor unit.

[0081] Reference Figure 3 , Figure 7 and Figure 8 In this embodiment, the telescopic transmission component 300 includes a telescopic transmission box 310.

[0082] The drive wheel 610, the driven wheel 620, and the transmission component 630 are all housed inside the telescopic transmission box 310. The drive motor 510 is located outside the telescopic transmission box 310. An input hole 311 is provided on the rear of the telescopic transmission box 310 at the position corresponding to the mounting hole of the drive wheel 610. The output shaft of the drive motor 510 passes through the input hole 311 and is connected to the mounting hole of the drive wheel 610. An output hole 312 is provided on the front of the telescopic transmission box 310 at the position corresponding to the mounting hole of the driven wheel 620. One end of the guide plate drive shaft 400 passes through the output hole 312 and is connected to the mounting hole of the driven wheel 620. The other end of the guide plate drive shaft 400 is connected to the air guide plate 200.

[0083] It is understandable that the telescopic transmission component 300 is configured as a telescopic transmission box 310, and the driving wheel 610, the driven wheel 620, and the rotating transmission component 630 are all housed within the telescopic transmission box 310. Furthermore, the telescopic transmission box 310 provides a relatively sealed space for the driving wheel 610, the driven wheel 620, and the rotating transmission component 630, preventing their operation from being affected by the surrounding environment (e.g., dust accumulation affecting transmission efficiency, or airborne particles becoming stuck at the connection points of the driving wheel 610, the driven wheel 620, and the rotating transmission component 630), and ensuring the service life of the driving wheel 610, the driven wheel 620, and the rotating transmission component 630.

[0084] Furthermore, the configuration of the input hole 311 and the output hole 312 allows the rotation drive motor 510 to transmit the output power to the drive wheel 610 installed inside the telescopic transmission box 310, and allows the rotation driven wheel 620 to output the power to the outside of the telescopic transmission box 310.

[0085] In this embodiment, the projected area of ​​the telescopic transmission box 310 (projected onto the left side of the telescopic transmission box 310 to obtain the area of ​​the shadow obtained on the right side of the telescopic transmission box 310; or projected onto the right side of the telescopic transmission box 310 to obtain the area of ​​the shadow obtained on the left side of the telescopic transmission box 310) is approximately 37 square centimeters. The entire telescopic transmission box 310 is compact in size, occupying minimal internal space in the air conditioner indoor unit. Furthermore, the overall structure of the telescopic transmission box 310, the drive wheel 610, the driven wheel 620, and the rotation transmission component 630 is ingenious and compact, greatly enhancing its practicality and applicability in the air conditioner indoor unit.

[0086] In an alternative embodiment, the driving wheel 610, the driven wheel 620, and the rotational transmission member 630 can be disposed on the outer side of the telescopic transmission member 300, thereby transmitting the power of the rotational drive member 500 to the guide plate drive shaft 400. In this case, the telescopic transmission member 300 may not be a box-like structure, but rather a plate extending in the front-rear direction.

[0087] Reference Figure 2 and Figure 3 In this embodiment, the telescopic transmission box 310 can be curved with a certain arc to save the length of the space inside the housing 100 used to install the telescopic transmission box 310 in the front-back direction, so that the housing 100 can have a smaller volume in the front-back direction.

[0088] Reference Figure 2 and Figure 3 In this embodiment, the indoor unit of the air conditioner also includes a telescopic limiting cover 700.

[0089] The telescopic limiting cover 700 is disposed on the housing 100 adjacent to the air outlet 110, and the front end of the telescopic limiting cover 700 is provided with a telescopic opening 710 for allowing the telescopic transmission box 310 to telescopically move. The telescopic transmission box 310 is telescopically disposed inside the telescopic limiting cover 700 in the front-back direction. The telescopic limiting cover 700 is used to limit the telescopic transmission box 310's telescopic movement in the front-back direction.

[0090] It is understood that the telescopic limiting cover 700 can at least cover the top, bottom and at least one side of the telescopic transmission box 310, thereby limiting the telescopic movement of the telescopic transmission box 310 in the front-back direction.

[0091] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, a clearance sliding hole 720 extending in the front-back direction is provided on one side of the telescopic limiting cover 700 corresponding to the input hole 311. The rotation drive motor 510 is located outside the telescopic limiting cover 700. The output shaft of the rotation drive motor 510 passes through the clearance sliding hole 720 and is inserted into the input hole 311. The clearance sliding hole 720 is used to allow the output shaft of the rotation drive motor 510 to slide within it as the telescopic transmission member 300 moves.

[0092] It is understandable that the telescopic transmission box 310 will telescopically extend relative to the telescopic limiting cover 700, and the rotary transmission motor mounted on the telescopic transmission box 310 will also move back and forth with the telescopic transmission box 310. In order to reduce the volume of the telescopic limiting cover 700, the rotary transmission motor is placed outside the telescopic limiting cover 700. Furthermore, by setting the sliding hole 720, the rotary transmission motor can be fixed to the telescopic transmission box 310, allowing the rotary transmission motor to transmit power to the drive wheel 610 inside the telescopic transmission box 310. At the same time, it also allows the rotary transmission motor to move back and forth with the telescopic transmission box 310, thereby ensuring that the air guide plate 200 can move and rotate relative to the air outlet 110.

[0093] Reference Figure 2 , Figure 3 , Figure 7 and Figure 8 In this embodiment, a telescopic rack 313 is provided on one side of the telescopic transmission box 310, which is arranged in the telescopic direction of the telescopic transmission member 300. The indoor unit of the air conditioner also includes a telescopic drive motor 314.

[0094] The telescopic drive motor 314 is mounted on the housing 100. The output shaft of the telescopic drive motor 314 is provided with a telescopic drive gear 315. The telescopic drive gear 315 is meshed with the telescopic rack 313 to cause the telescopic drive motor 314 to drive the telescopic transmission component 300 to perform telescopic movement.

[0095] It is understandable that the telescopic transmission box 310 can be telescopically moved in the front-back direction, which can be achieved by the aforementioned telescopic rack 313 and telescopic drive gear 315, so as to further enable the air guide plate 200 to move relative to the air outlet 110.

[0096] In an alternative embodiment, the telescopic transmission member 300 can be a telescopic rod or a telescopic cylinder (e.g., a pneumatic cylinder or hydraulic cylinder), with the telescopic end of the rod or cylinder facing forward, which similarly causes the telescopic transmission member 300 to extend and retract in the front-back direction. Furthermore, the rotational transmission mechanism 600 can employ the aforementioned belt and pulley scheme, with the belt being adjustable in tension or length. This allows the power of the drive wheel 610 to be transmitted to the driven wheel when the telescopic transmission member 300 is a telescopic rod or cylinder, enabling the air guide plate 200 to move and rotate relative to the air outlet 110 in the front-back direction.

[0097] Reference Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In this embodiment, the housing 100 includes one or more supports 120 disposed at the air outlet 110 and arranged laterally. Each support 120 has a telescopic cavity 121 extending in the front-rear direction and opening forward. The telescopic cavity 121 and the telescopic limiting cover 700 are correspondingly arranged laterally.

[0098] A telescopic transmission gear 316 meshes between the telescopic drive gear 315 and the telescopic rack 313. Furthermore,

[0099] The indoor unit of the air conditioner also includes a driven telescopic component 810 and a telescopic connecting rod 812.

[0100] The driven telescopic member 810 is telescopically disposed in the telescopic cavity 121 in the front-to-back direction. The driven telescopic member 810 and the telescopic transmission box 310 are correspondingly disposed in the transverse direction. The driven telescopic member 810 is provided with a driven rack 811 arranged in the front-to-back direction. The telescopic rack 313 and the driven rack 811 are respectively located on the same side of the telescopic transmission box 310 and the driven telescopic member 810 in the vertical direction. The air guide plate 200 is rotatably connected to the front end of the driven telescopic member 810.

[0101] The telescopic link 812 is arranged in the horizontal direction. A telescopic driven gear 813 is sleeved on the telescopic link 812 at the position corresponding to the driven rack 811. The telescopic driven gear 813 is meshed with the driven rack 811. The telescopic transmission gear 316 is sleeved on the telescopic link 812. The telescopic link 812 is used to drive the driven telescopic component 810 to perform synchronous telescopic movement when the telescopic transmission box 310 moves in the front-back direction.

[0102] Understandably, the aforementioned telescopic cavity 121 and driven telescopic member 810 are provided to ensure the stability of the movement of the air guide plate 200 relative to the air outlet 110 in the front-to-back direction and its rotation around the guide plate drive shaft 400. Furthermore, the telescopic transmission gear 316, telescopic connecting rod 812, driven rack 811, and telescopic driven gear 813 can cause the driven telescopic member 810 to move synchronously with the telescopic transmission member 300.

[0103] Reference Figure 6 and Figure 7 In this embodiment, the telescopic transmission box 310 is also provided with space for accommodating the telescopic transmission gear 316 and the telescopic drive gear 315.

[0104] Reference Figure 6 and Figure 7 In one embodiment of this invention, the telescopic rack 313 and the driven rack 811 are located on the same side of the telescopic transmission box 310 and the driven telescopic member 810 in the vertical direction, respectively. Specifically, the telescopic rack 313 can be positioned on the top of the telescopic transmission box 310, and the driven rack 811 can also be positioned on the top of the driven telescopic member 810. Simultaneously, the telescopic connecting rod 812 is positioned above the driven telescopic member 810 and the telescopic transmission box 310, and the telescopic driven gear 813 and the telescopic transmission gear 316 are also positioned above the driven telescopic member 810 and the telescopic transmission box 310.

[0105] In another embodiment of this invention, the telescopic rack 313 and the driven rack 811 are located on the same side of the telescopic transmission box 310 and the driven telescopic member 810 in the vertical direction, respectively. Specifically, the telescopic rack 313 can be located at the bottom of the telescopic transmission box 310, and the driven rack 811 can also be located at the bottom of the driven telescopic member 810. Simultaneously, the telescopic connecting rod 812 is located below the driven telescopic member 810 and the telescopic transmission box 310, and the telescopic driven gear 813 and the telescopic transmission gear 316 are also located below the driven telescopic member 810 and the telescopic transmission box 310.

[0106] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5In this embodiment, the housing 100 is provided with an air outlet duct 130 that communicates with the air outlet 110; and the housing 100 may include an air duct isolation cover 140 disposed between the air outlet duct 130 and the installation space 150, that is, the housing 100 is provided with an installation space 150 that is separated from the air outlet duct 130 by the air duct isolation cover 140.

[0107] The installation space 150 is located at the left-right end of the air outlet duct 130. The telescopic transmission component 300 and the telescopic drive motor 314 are both housed within the installation space 150. The duct isolation cover 140 includes an isolation plate 141 located between the air outlet duct 130 and the installation space 150, and a telescopic plate 142 connected to the isolation plate 141. The telescopic plate 142 is located in front of the installation space 150, and an opening 1421 is provided on the telescopic plate 142 corresponding to the telescopic port 710. The front end of the telescopic transmission box 310 passes through the opening 1421.

[0108] The telescopic limit cover 700 has an installation port 730 that opens toward the partition plate 141 (i.e., the installation port 730 is set toward the direction of the air outlet duct 130 to facilitate the installation of the telescopic connecting rod 812), and the telescopic limit cover 700 is fastened to the partition plate 141, and the partition plate 141 covers the installation port 730.

[0109] Understandably, the duct insulation cover 140 ensures air pressure within the outlet duct 130, reduces air loss, and guarantees the airflow of the indoor unit, thereby improving the user experience. Furthermore, the installation space 150 prevents components located within it from being affected by the external environment of the housing 100, ensuring that the air guide plate 200 can move normally relative to the air outlet 110 and rotate normally around the guide plate drive shaft 400.

[0110] Reference Figure 2 , Figure 3 and Figure 7 In this embodiment, the air guide plate 200 is provided with a drive support plate 210 extending in the front-rear direction, and the drive support plate 210 is provided with a drive hole 211 extending in the lateral direction.

[0111] The guide plate drive shaft 400 is connected to the drive hole 211. The cross-section of the guide plate drive shaft 400 is polygonal, and the cross-section of the guide plate drive shaft 400 has the same shape as the drive hole 211.

[0112] It is understandable that the aforementioned arrangement of the drive support plate 210 and its drive hole 211, as well as the guide plate drive shaft 400, enables the guide plate drive shaft 400 to drive the air guide plate 200 to rotate around it.

[0113] Reference Figure 2 , Figure 3 and Figure 7 In this embodiment, the cross-section of the guide plate drive shaft 400 and the shape of the drive hole 211 are "+" shaped.

[0114] In an alternative embodiment, the guide plate drive shaft 400 can be directly fixed to the inner side of the air guide plate 200, and the guide plate drive shaft 400 can also drive the air guide plate 200 to rotate around it.

[0115] Reference Figure 1 , Figure 4 and Figure 6 In this embodiment, the number of telescopic transmission component 300, guide plate drive shaft 400, rotation drive component 500 and rotation transmission mechanism 600 can be set to two, and respectively arranged at the left and right ends of the air conditioner indoor unit, so as to ensure the stability of the air guide plate 200 in moving relative to the air outlet 110 and rotating around the guide plate drive shaft 400.

[0116] Reference Figure 1 In this embodiment, the air conditioner indoor unit can be a ceiling-mounted air conditioner indoor unit, a wall-mounted air conditioner indoor unit, or a floor-standing air conditioner indoor unit. Of course, when the air conditioner indoor unit is a floor-standing air conditioner indoor unit, the directional terms described in this embodiment can be changed accordingly. For example, the left and right directions and the up and down directions can be replaced. All such changes should be within the protection scope of this embodiment.

[0117] Reference Figures 1 to 8 In this embodiment, when the indoor unit of the air conditioner is running, the telescopic drive motor 314 first drives the air guide plate 200 to extend out of the outside of the air outlet 110 and reach a preset position through the telescopic transmission component 300. Then, the rotation drive component 500 drives the air guide plate 200 to rotate around the guide plate drive shaft 400 in a predetermined rotation manner through the rotation transmission mechanism 600 and the guide plate drive shaft 400, so as to make the air supply mode of the indoor unit of the air conditioner more diversified and further meet the user's needs for air supply comfort or air supply mode diversity.

[0118] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
