Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment technology, and in particular to an indoor air conditioning unit and its oscillating device. 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 have a great demand for the diversified functions of air conditioners. For example, the wide-range airflow function of air conditioners, and the left and right swing airflow for rapid cooling or heating modes, all require the air conditioner's oscillating blades to work together to achieve these functions.

[0003] Currently, in existing technologies, whether it is a wall-mounted air conditioner indoor unit or a floor-standing air conditioner indoor unit, the swivel blades of the air conditioner are all arranged at the same angle to cooperate with the air guide plate to achieve different air delivery modes. This limits the diversified development of air delivery modes, resulting in a single air delivery mode for the air conditioner. In addition, existing air conditioners also have problems such as unnatural airflow and a strong feeling of direct airflow, all of which reduce the user experience. Summary of the Invention

[0004] One object of the present invention is to provide an air conditioning indoor unit and its louver device that can overcome at least one of the defects in the prior art.

[0005] A further objective of this invention is to enhance the diversity of air supply modes of the indoor unit of the air conditioner, making the airflow of the air conditioner more natural, reducing the direct blowing sensation of the airflow, and thus improving the user experience.

[0006] Specifically, the present invention provides a louver device for an indoor unit of an air conditioner, comprising:

[0007] An air outlet frame has an air outlet duct inside that connects to the air outlet of the indoor unit of the air conditioner. The air outlet duct is forward-facing and connected to the air outlet. The air outlet frame includes a mounting plate for forming the side wall of the air outlet duct. The mounting plate is arranged along the length of the air outlet.

[0008] Multiple blades are distributed along the length of the air outlet and are installed in the air outlet duct. The rotation axis of the blades is rotatably connected to the mounting plate.

[0009] Multiple drive rotating cylinder shafts are arranged corresponding to multiple swing blades, and are driven to be connected to the corresponding swing blades respectively. The drive rotating cylinder shafts are arranged along the length direction and are used to drive the corresponding swing blades to swing around their rotation axis in the length direction.

[0010] The cylinder shaft drive assembly is connected to multiple drive rotating cylinder shafts and is used to drive at least one drive rotating cylinder shaft to rotate asynchronously relative to the other drive rotating cylinder shafts, and to drive the drive rotating cylinder shafts to rotate synchronously.

[0011] Furthermore, the inner wall of the transmission rotating cylinder shaft is provided with a transmission slide rail extending helically along its axial direction, and at least one of the multiple transmission rotating cylinder shafts has a different pitch from the transmission slide rails of the others; and,

[0012] The cylinder shaft drive assembly includes:

[0013] A pull rod shaft extends along its length and passes through multiple transmission rotating cylinder shafts. A transmission slider is provided on its outer circumference at a position corresponding to the transmission rotating cylinder shaft. The transmission slider is slidably disposed in a corresponding transmission slide rail. The pull rod shaft is used to drive at least one transmission rotating cylinder shaft to rotate asynchronously relative to the other transmission rotating cylinder shafts through the transmission slider and the transmission slide rail when it moves relative to the transmission rotating cylinder shafts in the length direction. It is also used to drive the transmission rotating cylinder shafts to rotate synchronously through the transmission slider when rotating.

[0014] Furthermore, the transmission slide rail is a transmission groove, and the transmission slider is a transmission protrusion, which is slidably disposed within the transmission groove.

[0015] Furthermore, the number of transmission grooves on the inner wall of the transmission rotating cylinder shaft is set to be multiple, and the multiple transmission grooves are evenly distributed in the circumferential direction of the transmission rotating cylinder shaft, and the transmission protrusions are set to correspond to the transmission grooves in multiple ways.

[0016] Furthermore, the oscillating blades are located on the duct side of the mounting plate facing the air outlet duct, and the rotating shaft passes through the duct side to the leeward side of the mounting plate opposite the duct side. Both the transmission rotating cylinder shaft and the tie rod shaft are located on the leeward side.

[0017] The two adjacent transmission rotating cylinder shafts are arranged in abutting contact; and...

[0018] The cylinder shaft drive assembly also includes:

[0019] The transmission limiting mounting part is located on the leeward side and connected to the mounting plate. It abuts against both ends of one or more transmission rotating cylinder shafts to limit the displacement of the transmission rotating cylinder shafts in the length direction. It has a mounting through groove extending in the length direction, and the pull rod shaft is rotatably connected in the mounting through groove.

[0020] Furthermore, the cylinder shaft drive assembly also includes:

[0021] A pull-out bracket has a pull-out hole extending along its length, and one end of the pull rod shaft is rotatably connected to the pull-out hole. The pull-out bracket is used to allow the pull rod shaft to rotate through the pull-out hole.

[0022] The pull-out limiting part is connected to the pull rod shaft and is located on both sides of the pull-out bracket in the length direction; and,

[0023] The air conditioner indoor unit's louver mechanism also includes:

[0024] A pull-out drive unit is drivably connected to the pull-out bracket and is used to drive the pull rod shaft to move along the length direction through the abutment of the pull-out bracket and the pull-out limiting part.

[0025] Furthermore, the pull-out drive includes:

[0026] The pull-out drive motor has its pull rod motor shaft perpendicular to the pull rod shaft;

[0027] A pull-out transmission linkage has one end connected to the pull rod motor shaft and arranged radially along the pull rod motor shaft, and the other end has a pull-out sliding hole extending toward the pull rod motor shaft. The pull-out frame is provided with a pull-out protrusion extending in the direction of the pull rod motor shaft, and the pull-out protrusion is slidably disposed in the pull-out sliding hole.

[0028] Furthermore, the swivel mechanism of the air conditioner indoor unit also includes:

[0029] A rotation drive is motive-connected to the transmission rotating cylinder shaft located at the other end of the pull rod, used to drive the transmission rotating cylinder shaft located at the other end of the pull rod to rotate, and used to drive the pull rod shaft to rotate through the transmission rotating cylinder shaft located at the other end of the pull rod.

[0030] Furthermore, the oscillating blade is rotatably connected to the mounting plate, and the oscillating blade is located on the duct side of the mounting plate facing the air outlet duct. The rotating shaft passes through the duct side to the leeward side of the mounting plate opposite the duct side. Both the transmission rotating cylinder shaft and the tie rod shaft are located on the leeward side.

[0031] The rotation drive includes:

[0032] A rotary drive motor, whose motor shaft is driven and connected to a transmission rotary cylinder shaft located at the other end of the pull rod; and,

[0033] The two adjacent transmission rotating cylinder shafts are arranged in abutting contact; and...

[0034] The cylinder shaft drive assembly also includes:

[0035] The transmission limiting mounting part is connected to the mounting plate, located on the leeward side, and abuts against one or more transmission rotating cylinder shafts between it and the rotating motor shaft. It is used to limit the displacement of the transmission rotating cylinder shaft between it and the rotating motor shaft in the length direction, and has a mounting through groove extending in the length direction. The pull rod shaft is rotatably connected in the mounting through groove.

[0036] Furthermore, the vane is provided with a drive slider that is spaced apart from the axis of its rotation shaft, and the drive slider is oriented towards the corresponding transmission rotating cylinder shaft; and,

[0037] The outer wall of the transmission rotating cylinder shaft is provided with a drive slide rail that extends spirally along its axial direction. The drive slider is slidably disposed in the corresponding drive slide rail. When the transmission rotating cylinder shaft is used for rotation, the corresponding pendulum is driven to swing around its rotation axis by the drive slider and the drive slide rail.

[0038] Furthermore, the drive slide rail is a drive groove, and the drive slider is a drive protrusion, which is slidably disposed within the drive groove.

[0039] Furthermore, the drive slide includes a forward swing slide section and a reverse swing slide section, with the spiral directions of the forward swing slide section and the reverse swing slide section being opposite. The beginning end of the forward swing slide section is connected to the beginning end of the reverse swing slide section, and the end end of the forward swing slide section is connected to the end end of the reverse swing slide section, so that when the transmission rotating cylinder shaft rotates in one direction, the drive protrusion slides cyclically between the forward swing slide section and the reverse swing slide section, and the swing blade swings in the length direction.

[0040] Furthermore, the oscillating blade is rotatably connected to the mounting plate, and the oscillating blade is located on the duct side of the mounting plate facing the air outlet duct. The rotating shaft passes through the duct side to the leeward side of the mounting plate opposite the duct side. The driving slider is set on the rotating shaft, and both the driving slider and the transmission rotating cylinder shaft are located on the leeward side.

[0041] In particular, the present invention also provides an air conditioner indoor unit, including the aforementioned air conditioner indoor unit with swivel blades.

[0042] The oscillating blade device of the present invention, since each oscillating blade is independently driven by an independent transmission rotating cylinder shaft, and the cylinder shaft transmission assembly can drive at least one of the transmission rotating cylinder shafts to rotate asynchronously relative to the others, and to drive the transmission rotating cylinder shafts to rotate synchronously, allows at least one oscillating blade to swing to an angle different from the others by the cylinder shaft transmission assembly and the corresponding independent transmission rotating cylinder shaft. Multiple oscillating blades can swing simultaneously with at least one oscillating blade at a different oscillation angle than the others; that is, multiple oscillating blades can deliver air at different air delivery angles, enriching the air delivery modes of the air conditioner indoor unit. Furthermore, when multiple oscillating blades can deliver air at different air delivery angles, the direction of the airflow from the air outlet is disordered, and the airflow is more like a natural breeze, thus preventing the user from feeling a direct airflow. Therefore, the oscillating blade device of the present invention can improve the diversity of air delivery modes of the air conditioner indoor unit, making the airflow of the air conditioner more natural, reducing the direct airflow sensation, and improving the user experience.

[0043] The air conditioner indoor unit of the present invention also possesses the aforementioned louver device and thus the beneficial technical effects of the aforementioned louver device.

[0066] The following is combined with Figure 1 and Figure 2 The indoor unit of the air conditioner in this embodiment will be described in detail below.

[0067] Reference Figure 1 and Figure 2 In this embodiment, the indoor unit of the air conditioner may include a housing 100, and the air outlet 110 of the indoor unit of the air conditioner may be located on the front side (or the lower side, or the lower front side) of the housing 100.

[0068] Reference Figure 1 In this embodiment, the indoor unit of the air conditioner can be a wall-mounted indoor unit, and the length direction of the air outlet 110 is either left-right or horizontal.

[0069] Reference Figure 2 In this embodiment, the indoor unit of the air conditioner can also be a vertical indoor unit, in which case the length direction of the air outlet 110 is either up and down or vertical.

[0070] In this embodiment, the indoor unit of the air conditioner may include the swivel blade device described in the following embodiments.

[0071] It is understood that the air conditioner indoor unit of this embodiment also possesses the beneficial technical effects of the swing blade device of the following embodiment.

[0072] The following is combined with Figures 3 to 14 The leaf-shaped device of this embodiment will be described in detail below. Wherein, Figure 9 Part of the air outlet frame structure is hidden, and the leeward side of the mounting plate is shown. Figure 3 The air supply status of multiple louvers is shown, and at least one louver has a different air supply angle than the others, that is, multiple louvers are in a disordered air supply state. Figure 8 The display shows the air delivery status of multiple oscillating blades, and all the oscillating blades have the same air delivery angle, that is, multiple oscillating blades are in a directional air delivery state or a sweeping state.

[0073] Reference Figure 3 and Figure 4 In this embodiment, the oscillating blade device may include an air outlet frame 200, multiple oscillating blades 300, multiple transmission rotating cylinder shafts 400, and cylinder shaft transmission assembly 500.

[0074] The air outlet frame 200 has an air outlet duct 210 inside that is connected to the air outlet 110 of the indoor unit of the air conditioner. The air outlet duct 210 is connected to the air outlet 110 in a forward direction. The air outlet frame 200 includes a mounting plate 220 for forming the side wall of the air outlet duct 210. The mounting plate 220 is arranged along the length of the air outlet 110.

[0075] Multiple oscillating blades 300 are distributed along the length of the air outlet 110, and multiple oscillating blades 300 are disposed in the air outlet duct 210. The rotation shaft 310 of the oscillating blades 300 is rotatably connected to the mounting plate 220.

[0076] Multiple transmission rotating cylinder shafts 400 are correspondingly arranged with multiple swing blades 300. The multiple transmission rotating cylinder shafts 400 are respectively driven and connected to the corresponding swing blades 300. The transmission rotating cylinder shafts 400 are arranged along the length direction. The transmission rotating cylinder shafts 400 are used to rotatably drive the corresponding swing blades 300 to swing around their rotation axis 310 in the length direction.

[0077] The cylinder shaft drive assembly 500 is connected to multiple transmission rotating cylinder shafts 400. The cylinder shaft drive assembly 500 is used to drive at least one transmission rotating cylinder shaft 400 to rotate asynchronously relative to the other transmission rotating cylinder shafts 400, and the cylinder shaft drive assembly 500 is used to drive the transmission rotating cylinder shafts 400 to rotate synchronously.

[0078] In this embodiment, the swaying blade device, since each swaying blade 300 is independently driven by an independent transmission rotating cylinder shaft 400, and the cylinder shaft transmission assembly 500 can drive at least one transmission rotating cylinder shaft 400 to rotate asynchronously relative to the other transmission rotating cylinder shafts 400, and is used to drive the transmission rotating cylinder shafts 400 to rotate synchronously, at least one swaying blade 300 can be swung to an angle different from the other swaying blades 300 by the cylinder shaft transmission assembly 500 and the corresponding independent transmission rotating cylinder shaft 400, and multiple swaying blades 300 can swing simultaneously with at least one swaying blade 300 having a different swing angle than the other swaying blades 300. That is, multiple swaying blades 300 can deliver air with at least one swaying blade 300 having a different air delivery angle, thereby enriching the air delivery modes of the air conditioning indoor unit. Furthermore, when multiple swaying blades 300 can have different air delivery angles (e.g., at least one swaying blade 300 has a different air delivery angle), Figure 3 When air is supplied (as shown), the direction of the airflow from the air outlet 110 is turbulent, and the airflow is more like a natural breeze, so that the user will not feel the airflow blowing directly on them. Therefore, the louver device in this embodiment can improve the diversity of the air supply modes of the indoor unit of the air conditioner, making the airflow of the air conditioner more natural, reducing the feeling of direct airflow, and improving the user experience.

[0079] It should be noted that at least one drive rotating cylinder shaft 400 rotates asynchronously relative to the other drive rotating cylinder shafts 400. This can be one, two, three, or more drive rotating cylinder shafts 400 rotating asynchronously relative to the other drive rotating cylinder shafts 400, or all drive rotating cylinder shafts 400 rotating asynchronously among themselves. Furthermore, multiple swing blades 300 can deliver air at different air delivery angles (one, two, three, more, or all). With multiple swing blades 300 delivering air in different air delivery states, the air delivery mode of the indoor unit of the air conditioner is different, thus greatly enriching the air delivery modes of the indoor unit.

[0080] It should also be noted that if the air outlet frame 200 extends vertically and is arranged on a vertical air conditioner indoor unit, then the mounting plate 220 can be the left or right duct wall panel of the air outlet frame 200 used to form the air outlet duct 210. Furthermore, the air outlet frame 200 (base) can also extend horizontally and be arranged on a wall-mounted air conditioner indoor unit, then the mounting plate 220 can be the upper or lower duct wall panel of the air outlet frame 200 (base) used to form the air outlet duct 210.

[0081] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7In this embodiment, a transmission slide rail 410 extending spirally along its axial direction is provided on the inner wall of the transmission rotating cylinder shaft 400, and at least one of the multiple transmission rotating cylinder shafts 400 has a different pitch from the transmission slide rail 410 of the others.

[0082] Furthermore, the cylinder shaft drive assembly 500 includes a tie rod shaft 510.

[0083] The pull rod shaft 510 extends along the length direction and passes through multiple transmission rotating cylinder shafts 400. A transmission slider 520 is provided on the outer periphery of the pull rod shaft 510 at a position corresponding to the transmission rotating cylinder shaft 400. The transmission slider 520 is slidably disposed in the corresponding transmission slide rail 410. When the pull rod shaft 510 moves relative to the transmission rotating cylinder shaft 400 in the length direction, it drives at least one transmission rotating cylinder shaft 400 to rotate asynchronously relative to the other transmission rotating cylinder shafts 400 through the transmission slider 520 and the transmission slide rail 410. When the pull rod shaft 510 rotates, it drives the transmission rotating cylinder shaft 400 to rotate synchronously through the transmission slider 520.

[0084] It is understood that the transmission rotating cylinder shaft 400 is a hollow structure, that is, a central hole extending along its axial direction is opened inside the transmission rotating cylinder shaft 400, and a transmission slide rail 410 extending spirally along its axial direction can be provided on the inner wall of the transmission rotating cylinder shaft 400. Furthermore, the pull rod shaft 510 with a transmission slider 520 on its outer periphery can be inserted into the transmission rotating cylinder shaft 400. When the pull rod shaft 510 is pulled relative to the transmission rotating cylinder shaft 400 in the length direction of the air outlet 110 (or in the axial direction of the pull rod shaft 510 and the transmission rotating cylinder shaft 400), the transmission rotating cylinder shaft 400 can rotate under the action of the transmission slider 520 and the spiral transmission slide rail 410.

[0085] Furthermore, among the multiple transmission rotating cylinder shafts 400, the pitch of the transmission slide rail 410 on the inner wall of at least one transmission rotating cylinder shaft 400 is set to be different from the pitch of the transmission slide rail 410 of the other transmission rotating cylinder shafts 400 (including the pitch of the transmission slide rail 410 of each transmission rotating cylinder shaft 400 being different). Thus, when the pull rod shaft 510 moves in the length direction relative to all the transmission rotating cylinder shafts 400, the cylinder shaft transmission assembly 500 can cause at least one of the multiple transmission rotating cylinder shafts 400 to rotate asynchronously with the other transmission rotating cylinder shafts 400, so that at least one of the multiple swing blades 300 will rotate to a position with an angle different from the other swing blades 300.

[0086] When the pull rod shaft 510 rotates, the transmission slider 520 on the pull rod shaft 510 can drive its corresponding transmission rotating cylinder shaft 400 to rotate, and thus multiple transmission rotating cylinder shafts 400 can rotate synchronously.

[0087] Additionally, refer to Figure 8 When the pull rod shaft 510 is configured to move back to its initial position along its length, all the oscillating blades 300 will be reset to the same swing angle or air delivery angle. Then, the transmission rotating cylinder shaft 400 is configured to rotate synchronously, and each oscillating blade 300 will swing in the same direction, causing the airflow to be directed or swept.

[0088] In summary, the cylinder shaft transmission assembly 500 of this embodiment can drive at least one transmission rotating cylinder shaft 400 to rotate asynchronously relative to the other transmission rotating cylinder shafts 400, and can also drive all transmission rotating cylinder shafts 400 to rotate synchronously. This enhances the diversity of air supply modes of the indoor unit of the air conditioner, makes the airflow of the air conditioner more natural, reduces the direct blowing sensation of the airflow, and improves the user experience.

[0089] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In this embodiment, the transmission slide rail 410 can be configured as a transmission groove 411, and the transmission slider 520 can be configured as a transmission protrusion 521. The transmission protrusion 521 is slidably disposed in the transmission groove 411 so that the transmission slider 520 can be slidably disposed in the corresponding transmission slide rail 410.

[0090] Reference Figure 5 and Figure 7 In this embodiment, the number of transmission grooves 411 on the inner wall of the transmission rotating cylinder shaft 400 is set to be multiple, and the multiple transmission grooves 411 are evenly distributed in the circumferential direction of the transmission rotating cylinder shaft 400, and the transmission protrusions 521 are set to be multiple corresponding to the transmission grooves 411.

[0091] It is understandable that multiple transmission grooves 411 and transmission protrusions 521 are correspondingly set to ensure the stability of transmission between the transmission rotating cylinder shaft 400 and the tie rod shaft 510.

[0092] In an alternative embodiment, a cylinder drive gear set may be fitted onto a drive rotating cylinder shaft 400, the cylinder drive gear set may include a cylinder synchronous gear and a cylinder asynchronous gear, and the cylinder shaft drive assembly 500 may include a pull rod shaft 510.

[0093] The pull rod shaft 510 extends along the length direction and is located close to multiple adjacent transmission rotating cylinder shafts 400. A pull rod gear set is sleeved on the pull rod shaft 510 at a position corresponding to one of the transmission rotating cylinder shafts 400. The pull rod gear set may include a rod synchronous gear and a rod asynchronous gear.

[0094] The axial distance between the synchronous gear and the asynchronous gear on the transmission rotating cylinder shaft 400 is different from the axial distance between the synchronous gear and the asynchronous gear on the tie rod shaft 510. The center distance between the synchronous gear and the synchronous gear is the same as the center distance between the asynchronous gear and the asynchronous gear. Therefore, the tie rod shaft 510 can be configured to move in the length direction to switch the transmission rotating cylinder shaft 400 and the tie rod shaft 510 to be driven by the synchronous gear and the synchronous gear or the asynchronous gear and the asynchronous gear. Furthermore, the tie rod shaft 510 can be configured to drive the transmission rotating cylinder shaft 400 to rotate through the tie rod gear set and the cylinder transmission gear set when rotating.

[0095] The pitch circle diameter and number of teeth of the synchronous gears between each transmission rotating cylinder shaft 400 are the same, and the pitch circle diameter and number of teeth of the synchronous gears on the tie rod shaft 510 are also the same. Moreover, among the multiple transmission rotating cylinder shafts 400, at least one transmission rotating cylinder shaft 400 has a different pitch circle diameter and number of teeth of its asynchronous gear compared to the others.

[0096] Furthermore, when it is necessary to configure at least one drive rotating cylinder shaft 400 to rotate asynchronously relative to the other drive rotating cylinder shafts 400, the transmission between the switch rod shaft 510 and the multiple drive rotating cylinder shafts 400 is achieved through a rod asynchronous gear and a cylinder asynchronous gear. After configuring at least one oscillating blade 300 to rotate at an angle different from the other oscillating blades 300, the transmission between the switch rod shaft 510 and the multiple drive rotating cylinder shafts 400 can be switched back to a rod synchronous gear and a cylinder synchronous gear, so that the multiple oscillating blades 300 can deliver air with at least one oscillating blade 300 having a different air delivery angle.

[0097] In summary, this embodiment, through the configuration of the cylinder drive gear set and the tie rod gear set, can also enable the cylinder shaft drive assembly 500 to drive at least one drive rotating cylinder shaft 400 to rotate asynchronously relative to the other drive rotating cylinder shafts 400, and to drive the drive rotating cylinder shafts 400 to rotate synchronously.

[0098] Reference Figure 3 In this embodiment, the oscillating blade 300 is rotatably connected to the mounting plate 220, and the oscillating blade 300 is located on the duct side of the mounting plate 220 facing the air outlet duct 210. The rotating shaft 310 passes through the duct side to the leeward side of the mounting plate 220 opposite to the duct side. The transmission rotating cylinder shaft 400 and the pull rod shaft 510 are both located on the leeward side.

[0099] It is understood that by placing the transmission rotating cylinder shaft 400 and the pull rod shaft 510 (and the transmission limiting mounting part 530 in the following embodiment) on the leeward side, the influence of the transmission rotating cylinder shaft 400 and the pull rod shaft 510 (and the transmission limiting mounting part 530 in the following embodiment) on the airflow can be effectively avoided, ensuring the airflow rate and the user experience.

[0100] Reference Figure 3 , Figure 8 and Figure 9 In this embodiment, two adjacent transmission rotating cylinder shafts 400 are abutted together. Additionally, in this embodiment, a thrust bearing can be provided between two adjacent transmission rotating cylinder shafts 400 to ensure stability and smoothness during rotation in opposite directions, thus ensuring the normal operation of the oscillating blade device.

[0101] Reference Figure 3 , Figure 8 , Figure 9 and Figure 10 In this embodiment, the cylinder shaft transmission assembly 500 may further include a transmission limiting mounting part 530.

[0102] The transmission limiting mounting part 530 is located on the leeward side and is connected to the mounting plate 220. The transmission limiting mounting part 530 has a mounting through groove 531 extending along the length direction, and the pull rod shaft 510 is rotatably connected to the mounting through groove 531.

[0103] Understandably, the transmission limit mounting part 530 can mount the tie rod shaft 510 on the mounting plate 220 so as to mount the tie rod shaft 510 and the plurality of transmission rotating cylinder shafts 400 together on the mounting plate 220.

[0104] Reference Figure 3 , Figure 8 , Figure 9 and Figure 10 In one embodiment of the transmission limiting mounting part 530 in this embodiment, the transmission limiting mounting part 530 abuts against both ends of one or more transmission rotating cylinder shafts 400, and the transmission limiting mounting part 530 is used to limit the displacement of the transmission rotating cylinder shafts 400 between the transmission limiting mounting parts 530 in the length direction.

[0105] It is understandable that by abutting against each other multiple transmission rotating cylinder shafts 400 and providing transmission limit mounting parts 530 at both ends of the multiple transmission rotating cylinder shafts 400, the situation where the transmission slider 520 moves the transmission rotating cylinder shaft 400 in the length direction through the action of the transmission slide rail 410 can be avoided when the pull rod shaft 510 rotates. This ensures that the cylinder shaft transmission assembly 500 can drive at least one transmission rotating cylinder shaft 400 to rotate asynchronously relative to the other transmission rotating cylinder shafts 400, and drive all transmission rotating cylinder shafts 400 to rotate synchronously, thus ensuring the operation of the swing blade device.

[0106] Reference Figure 5 In this embodiment, the transmission slide rail 410 provided on each transmission rotating cylinder shaft 400 can be set with a larger pitch in the axial spiral of the transmission rotating cylinder shaft 400, so as to further avoid the situation where the transmission slider 520 moves the transmission rotating cylinder shaft 400 in the length direction through the action of the transmission slide rail 410 when the pull rod shaft 510 rotates, thus ensuring the operation of the swing blade device.

[0107] Reference Figure 10 In this embodiment, the cylindrical shaft transmission assembly 500 may further include a pull-out bracket 540 and a pull-out limiting part 550. The louver device of the air conditioner indoor unit may further include a pull-out drive component 560.

[0108] The pull-out bracket 540 has a pull-out hole extending along the length direction. One end of the pull rod shaft 510 is rotatably connected to the pull-out hole. The pull-out bracket 540 is used to allow the pull rod shaft 510 to rotate through the pull-out hole.

[0109] The pull-out limiting part 550 is connected to the pull rod shaft 510, and the pull-out limiting part 550 is located on both sides of the pull-out bracket 540 in the length direction.

[0110] The pull-out drive 560 is motive-connected to the pull-out bracket 540, and the pull-out drive 560 is used to drive the pull rod shaft 510 to move along the length direction by the abutment of the pull-out bracket 540 and the pull-out limiting part 550.

[0111] Understandably, with the pull-out bracket 540 and the pull-out limit part 550, the pull rod shaft 510 can rotate and move in the length direction under the drive of the pull-out drive member 560.

[0112] In one embodiment of the pull-out drive component 560 in this example, the pull-out drive component 560 can be a cylinder, hydraulic cylinder, or the like. The cylinder body is arranged along the length direction or the axial direction of the pull rod shaft 510, and the piston rod of the cylinder body is connected to the pull-out bracket 540. Thus, the extension and retraction of the cylinder body can drive the pull rod shaft 510 to move along the length direction. Therefore, the pull-out drive component 560 can drive the pull rod shaft 510 to move along the length direction through the contact between the pull-out bracket 540 and the pull-out limiting part 550.

[0113] Reference Figure 10 In another embodiment of the pull-out drive component 560 in this example, the pull-out drive component 560 includes a pull-out drive motor 561 and a pull-out transmission link 562.

[0114] The pull rod motor shaft 5611 of the pull drive motor 561 is perpendicular to the pull rod shaft 510.

[0115] One end of the pull-out transmission link 562 is connected to the pull rod motor shaft 5611, and the pull-out transmission link 562 is arranged radially along the pull rod motor shaft 5611. The other end of the pull-out transmission link 562 is provided with a pull-out sliding hole 5621 extending toward the pull rod motor shaft 5611. The pull-out bracket 540 is provided with a pull-out protrusion 541 extending in the direction arranged along the pull rod motor shaft 5611. The pull-out protrusion 541 is slidably disposed in the pull-out sliding hole 5621.

[0116] Understandably, the pull-out transmission linkage 562 can convert the reciprocating rotation of the pull rod motor shaft 5611 of the pull-out drive motor 561 into the reciprocating movement of the pull-out frame 540 (and the pull rod shaft 510) in the length direction, so that the pull-out drive member 560 can drive the pull rod shaft 510 to move in the length direction through the abutment of the pull-out frame 540 and the pull-out limiting part 550.

[0117] Reference Figure 11 In this embodiment, the swing blade device of the air conditioner indoor unit also includes a rotation drive 600.

[0118] The rotation drive 600 is motive-connected to the transmission rotation cylinder shaft 400 located at the other end of the pull rod. The rotation drive 600 is used to drive the transmission rotation cylinder shaft 400 located at the other end of the pull rod to rotate, and the rotation drive 600 is used to drive the pull rod shaft 510 to rotate through the transmission rotation cylinder shaft 400 located at the other end of the pull rod.

[0119] It is understandable that the specific implementation of the rotation of the pull rod can be as follows: first, the rotation drive 600 drives the transmission rotation cylinder shaft 400 furthest from the pull rod frame 540 to rotate, and then the rotation of the transmission rotation cylinder shaft 400 drives the pull rod to rotate through the transmission slider 520 inside the transmission rotation cylinder shaft 400. In turn, the pull rod can drive the other transmission rotation cylinder shafts 400 to rotate synchronously, so that the transmission rotation cylinder shaft 400 can rotatably drive the corresponding swing blade 300 to swing around its rotation axis 310.

[0120] Reference Figure 11 In this embodiment, the rotation drive 600 may further include a rotation drive motor 610.

[0121] The rotation drive motor 610's rotation motor shaft 611 is driven to be connected to the transmission rotation cylinder shaft 400 located at the other end of the pull rod, so that the rotation drive 600 is driven to be connected to the transmission rotation cylinder shaft 400 furthest from the pull rod 540.

[0122] Reference Figure 9 and Figure 11 In this embodiment, the axial length of the transmission rotating cylinder shaft 400 furthest from the pull-out bracket 540 can be set to be relatively long. Therefore, within the transmission rotating cylinder shaft 400, a pull rod motor gap can be left between the rotating motor shaft 611 and the pull rod shaft 510 to allow the pull rod shaft 510 to move relative to the transmission rotating cylinder shaft 400 in the length direction. Thus, the pull rod shaft 510 can be configured to allow at least one of the multiple transmission rotating cylinder shafts 400 to rotate asynchronously.

[0123] Reference Figure 9 and Figure 11 In another embodiment of the transmission limiting mounting part 530 in this embodiment, one or more transmission rotating cylinder shafts 400 abut against the transmission limiting mounting part 530 and the rotating motor shaft 611. The transmission limiting mounting part 530 is also used to limit the displacement of the transmission rotating cylinder shaft 400 between the transmission limiting mounting part 530 and the rotating motor shaft 611 in the length direction.

[0124] It is understood that, since the transmission rotating cylinder shaft 400 furthest from the drawer 540 in the aforementioned embodiment is directly connected to the rotating motor shaft 611 of the rotating drive motor 610, the two ends of one or more transmission rotating cylinder shafts 400 furthest from the drawer 540 can be limited by the rotating motor shaft 611 and the transmission limiting mounting part 530. This is to prevent the transmission slider 520 from causing one or more transmission rotating cylinder shafts 400 furthest from the drawer 540 to move in the length direction when the pull rod shaft 510 rotates. This ensures that the cylinder shaft transmission assembly 500 can drive at least one transmission rotating cylinder shaft 400 to rotate asynchronously relative to the other transmission rotating cylinder shafts 400, and drive all transmission rotating cylinder shafts 400 to rotate synchronously, thus ensuring the operation of the swing blade device.

[0125] In an alternative embodiment, the drive motor 610 and the transmission rotating cylinder shaft 400 furthest from the drawer 540 can be driven by a gear set. Furthermore, the drive motor shaft 611 no longer serves to limit the transmission rotating cylinder shaft 400 furthest from the drawer 540. Instead, it adopts the scheme in the aforementioned embodiment where the transmission limiting mounting part 530 abuts against both ends of one or more transmission rotating cylinder shafts 400. Similarly, it can cause the cylinder shaft transmission assembly 500 to drive at least one transmission rotating cylinder shaft 400 to rotate asynchronously relative to the other transmission rotating cylinder shafts 400, and drive all transmission rotating cylinder shafts 400 to rotate synchronously, ensuring the operation of the swing blade device.

[0126] Reference Figure 4 and Figure 12 In this embodiment, the oscillating blade 300 is provided with a drive slider 320 spaced apart from the axis of its rotation shaft 310, and the drive slider 320 is positioned toward the corresponding transmission rotating cylinder shaft 400.

[0127] The outer wall of the transmission rotating cylinder shaft 400 is provided with a drive slide rail 420 that extends spirally along its axial direction. The drive slider 320 is slidably disposed in the corresponding drive slide rail 420. When the transmission rotating cylinder shaft 400 is used for rotation, the corresponding swing blade 300 is driven to swing around its rotation axis 310 by the drive slider 320 and the drive slide rail 420.

[0128] It is understood that the pendulum 300 is slidably mounted in the corresponding drive slide rail 420 via the drive slider 320 thereon, so that the pendulum 300 can swing around the rotation axis 310 thereon.

[0129] Reference Figure 4 and Figure 12In this embodiment, the drive slide rail 420 is a drive slide groove 421, and the drive slider 320 is a drive protrusion 321. The drive protrusion 321 is slidably disposed in the drive slide groove 421 so that the drive slider 320 can be slidably disposed in the drive slide rail 420.

[0130] Reference Figure 13 and Figure 14 In this embodiment, the drive slide 421 includes a forward swing slide section 4211 and a reverse swing slide section 4212. The spiral directions of the forward swing slide section 4211 and the reverse swing slide section 4212 are opposite, and the first end of the forward swing slide section 4211 is connected to the first end of the reverse swing slide section 4212, and the tail end of the forward swing slide section 4211 is connected to the tail end of the reverse swing slide section 4212, so that when the transmission rotating cylinder shaft 400 rotates in one direction, the drive protrusion 321 slides cyclically between the forward swing slide section 4211 and the reverse swing slide section 4212, and the swing blade 300 swings in the length direction.

[0131] It should be understood that the drive slide 421 can be configured as a forward swing slide section 4211 and a reverse swing slide section 4212 with opposite spiral directions. Furthermore, the beginnings of the forward swing slide section 4211 and the end of the reverse swing slide section 4212 are connected, and the end of the drive slide section 4212 is connected. Therefore, the transmission rotating cylinder shaft 400 rotates in one direction without reciprocating. The drive protrusion 321 can then slide cyclically between the forward swing slide section 4211 and the reverse swing slide section 4212, causing the swing blades 300 to swing in the length direction, thus causing the air conditioner indoor unit to perform air sweeping. Therefore, the rotation drive motor 610 in the aforementioned embodiment does not need to reciprocate, increasing the service life of the rotation drive motor 610. The swing of the swing blades 300 can be achieved without an excessively high-performance motor, reducing the production cost of the swing blade device and the air conditioner indoor unit.

[0132] Reference Figure 3 and Figure 12 In this embodiment, the drive slider 320 is disposed on the rotating shaft 310, and both the drive slider 320 and the transmission rotating cylinder shaft 400 are located on the leeward side, so as to ensure the flow rate of the air outlet, ensure the user experience, and at the same time ensure the transmission efficiency and effect between the transmission rotating cylinder shaft 400 and the swing blade 300.

[0133] In an alternative embodiment, the difference from the above is that a bevel gear is fitted onto the rotating shaft 310 of the oscillating blade 300. A rotating bevel gear is fitted onto the transmission rotating cylinder shaft 400 at a position corresponding to the bevel gear of the oscillating blade 300, and the rotating bevel gear is meshed with the bevel gear of the oscillating blade 300. Thus, the transmission rotating cylinder shaft 400 can also rotatably drive the corresponding oscillating blade 300 to swing around its rotating shaft 310, and the oscillating blade 300 can swing around its rotating shaft 310.

[0134] Reference Figures 1 to 14 In this embodiment, taking the example that the pitch of the transmission slide rails 410 on each transmission rotating cylinder shaft 400 is different, the working process of the indoor unit of the air conditioner can be as follows:

[0135] When the indoor unit of the air conditioner needs to supply air in an irregular order, firstly, the pull-out drive motor 561 drives the pull rod shaft 510 to move relative to the transmission rotating cylinder shaft 400 in the length direction through the pull-out transmission linkage 562, the pull-out limit part 550, and the pull-out bracket 540. This drives the pull rod shaft 510 to move from its initial position to a predetermined position. Then, under the action of the transmission slider 520 and the transmission slide rails 410 with different pitches, all the transmission rotating cylinder shafts 400 will rotate asynchronously. Furthermore, with all the transmission rotating cylinder shafts 400 rotating asynchronously, each swing blade 300 can swing at different oscillation speeds through the action of the drive slider 320 and the drive slide rails 420. After the pull rod shaft 510 moves to the preset position, the pull-out drive motor 561 stops driving the pull rod shaft 510, and each swing blade 300 can swing to different angles.

[0136] Secondly, the drive motor 610 drives the transmission cylinder furthest from the pull rod motor shaft 5611 to rotate, which in turn drives the pull rod to rotate. Furthermore, under the action of each transmission slider 520, all transmission cylinders rotate synchronously. Through the action of the drive slider 320 and the drive rail 420, all the oscillating blades 300 can oscillate at the same oscillation speed but different oscillation angles, causing the airflow to flow out of the outlet 110 in a disordered (i.e., turbulent) manner.

[0137] When the indoor unit of the air conditioner needs directional air supply or air sweeping, the pull-out drive motor 561 first drives the pull rod shaft 510 to move back to the initial position through the pull-out transmission link 562, the pull-out limit part 550 and the pull-out bracket 540. Under the action of the transmission slider 520 and the transmission slide rails 410 with different pitches, all the transmission rotating cylinder shafts 400 will rotate asynchronously. Through the action of the drive slider 320 and the drive slide rail 420, each swing blade 300 can swing back to the same angle or the same air supply direction.

[0138] Secondly, the drive motor 610 drives the transmission cylinder furthest from the pull rod motor shaft 5611 to rotate, which in turn drives the pull rod to rotate. Furthermore, under the action of each transmission slider 520, all transmission cylinders rotate synchronously. Through the action of the drive slider 320 and the drive rail 420, all the oscillating blades 300 can oscillate at the same oscillation speed and the same oscillation angle to complete directional air delivery or sweeping.

[0139] Therefore, those skilled in the art should recognize that although numerous 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 invention.
