Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, and in particular relates to a wall-mounted air conditioner indoor unit. Background Technology

[0002] A typical indoor unit of a wall-mounted air conditioner includes a casing and an indoor heat exchanger and a heat exchange fan located inside the casing. The indoor heat exchanger is used to exchange heat with the airflow inside the casing. The heat exchange fan drives indoor air to enter the casing through the air inlet at the top of the casing. After exchanging heat with the indoor heat exchanger, the air flows out through the air outlet at the bottom front of the casing.

[0003] The air conditioner's air outlet extends along the length of the unit's casing. A deflector is typically installed at the air outlet, and this deflector is usually controlled to open or close the air outlet via a drive mechanism. When the air outlet is open, the deflector guides the airflow from it, changing the direction of the airflow and allowing users to adjust the airflow direction as needed.

[0004] Existing drive mechanisms for air deflectors require limiting the movement of the push rod during its descent to ensure accurate trajectory. Related technologies typically employ multiple rollers that work in conjunction with the push rod to form a motion track, which to some extent ensures linear or curved movement. However, this roller-based limiting method suffers from problems such as a large number of parts, complex structure, insufficient reliability, increased manufacturing costs, and assembly difficulty. It can also easily lead to push rod misalignment or jamming during movement, affecting the normal opening and closing of the air deflector. Furthermore, the rollers are prone to wear over long-term use, reducing the limiting effect and impacting the product's durability and stability. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore,

[0006] This utility model provides a wall-mounted air conditioner indoor unit, which includes:

[0007] The casing has an air conditioning inlet and an air conditioning outlet on its top and front bottom, respectively.

[0008] An indoor heat exchanger is located inside the casing and is used to exchange heat with the air inside the casing.

[0017] The above technical solution has the following advantages or beneficial effects: By setting a ball bearing bracket between the drive box and the push rod, the thickness and width directions of the push rod are limited by the rolling action of the ball bearing bracket itself and the balls on it in the first and second slide rails, and a motion trajectory is formed in the direction of movement, thus playing a guiding role. This effectively solves the problem of possible displacement of the push rod during movement, ensuring that the push rod can move along a precise predetermined trajectory, ensuring that the air guide plate can accurately and smoothly open or close the air conditioning outlet, and improving the operational stability and reliability of the indoor unit of the air conditioner.

The bracket body provides stable support and positioning for the ball bearing, ensuring that the ball bearing can rotate smoothly along the direction of push rod movement, thereby better playing the limiting and guiding role and improving the reliability and durability of the ball bearing bracket.

[0023] According to an embodiment of this disclosure, two first slide rails are spaced apart on the side of the drive box along its own width direction, and two second slide rails are spaced apart on the side of the push rod along its own width direction.

[0024] The above technical solution has the following advantages or beneficial effects: by setting two first and second slides, the constraint on the trajectory of the push rod is further enhanced, the stability and accuracy of the push rod movement are improved, and the pushing or retracting action of the air guide plate is made smoother and more accurate.

[0029] When the push motor is working, the gear and the rack work together to drive the push rod to move.

[0030] The above technical solution has the following advantages or beneficial effects: the push-out drive mechanism uses gear and rack transmission, which makes its structure simple and compact, easy to install, and has high transmission efficiency. It can accurately control the push-out and retraction of the push rod, thereby improving the accuracy and reliability of the drive.

[0031] According to an embodiment of this disclosure, the indoor unit of the wall-mounted air conditioner further includes a rotary drive mechanism installed on the extended end. The rotary drive mechanism is connected to the air guide plate and is used to drive the air guide plate to rotate. The rotation axis of the air guide plate extends along its own length direction.

[0032] The above technical solution has the following advantages or beneficial effects: by setting a rotary drive mechanism at the extended end of the push rod, and connecting the rotary drive mechanism with the air guide plate, the air guide plate can be driven to rotate around its length axis, thereby realizing the function of adjusting the air outlet direction of the air guide plate.

[0033] According to an embodiment of this disclosure, the push rod includes:

[0034] A push rod base is mounted on the housing;

[0035] A push rod cover is fitted onto the push rod base, and the second slide rail is provided on the push rod base and the push rod cover;

[0036] An assembly cavity for accommodating the rotary drive mechanism is defined between the push rod cover and the push rod base, and the drive part of the rotary drive mechanism passes through the push rod base and is connected to the air guide plate.

[0037] The above technical solution has the following advantages or beneficial effects: the push rod adopts a split structure that combines the push rod base and the push rod cover, which not only provides installation space for the rotary drive mechanism and facilitates the assembly and maintenance of the rotary drive mechanism, but also ensures the overall strength and stability of the push rod and realizes the stable movement of the push rod.

[0038] According to an embodiment of this disclosure, the rotary drive mechanism includes a rotary motor, the ejection drive mechanism includes an ejection motor, and the bodies of the rotary motor and the ejection motor are respectively located on both sides of the push rod cover.

[0039] The above technical solution has the following advantages or beneficial effects: the main body of the rotary motor and the main body of the push-out motor are located on both sides of the push rod cover. This layout makes the rotary motor and the push-out motor independent of each other, avoiding mutual interference between them during installation and operation, ensuring the normal driving and heat dissipation performance of each motor, improving the service life and reliability of the motor, and also facilitating individual maintenance and replacement of the motor, reducing maintenance costs and difficulties.

[0040] According to an embodiment of this disclosure, a damping block is protruding from the push rod, the damping block is located on one side of the first slide rail, and the damping block is in contact with the drive box.

[0041] The above technical solution has the following advantages or beneficial effects: the damping block contacts the drive box, increasing the friction between the push rod and the drive box, thereby offsetting part of the gravity, slowing down the speed of natural descent due to gravity, and avoiding the problem of jamming during the push-out process caused by the push rod's natural descent speed being greater than the push-out speed of the push rod driven by the push-out mechanism.

[0042] According to embodiments of this disclosure, the driver box includes:

[0043] A box, which is hollow inside and has an opening on one side;

[0044] A cover is provided on the open end of the box body. The cover and the box body together define the receiving cavity and the opening communicating with the receiving cavity. The opening allows the push rod to pass through. The box body and the cover body are provided with the first slide rail.

[0045] Rollers are disposed on the housing and located on both sides of the push rod in the width direction. The rollers are positioned close to the opening relative to the ball bearing bracket. The rollers are rotatable relative to the side of the push rod in the width direction, so that the push rod and the two side walls of the opening in the width direction of the push rod are spaced apart from each other.

[0046] The above technical solution has the following advantages or beneficial effects: the drive box adopts a split structure, which facilitates the assembly of the push rod. At the same time, by setting rollers, the push rod can be spaced apart from the two side walls of the opening during the movement, thereby effectively avoiding interference between the push rod and the side walls of the opening during the movement, ensuring the stability of the push rod movement, and realizing the limiting function of the push rod in its own width direction.

[0047] This utility model also provides a wall-mounted air conditioner indoor unit, which includes:

[0048] The casing has an air conditioning inlet and an air conditioning outlet on its top and front bottom, respectively.

[0049] An indoor heat exchanger is located inside the casing and is used to exchange heat with the air inside the casing.

[0050] A heat exchange fan is disposed inside the housing and located below the indoor heat exchanger;

[0051] An air guide plate is movably disposed at the air conditioner outlet to open or close the air conditioner outlet;

[0052] A drive box is fixedly connected to the housing, and a receiving cavity is defined inside the drive box;

[0053] A push rod is partially disposed in the receiving cavity and one end of it is connected to the air guide plate. The push rod can move relative to the drive box along its own extension direction.

[0054] A ball bearing bracket is installed between the push rod and the drive box, and the oppositely arranged side walls of the ball bearing bracket have multiple balls;

[0055] The drive box and the push rod have slides on their opposite sides, the slides extend along the length of the push rod, and multiple slides are spaced apart along the thickness of the push rod; the slide on the drive box is defined as the first slide, and the slide on the push rod is defined as the second slide;

[0056] The ball bearing is partially embedded in the first slide rail and the second slide rail, and rolls in cooperation with the first slide rail and the second slide rail. The rolling axis of the ball bearing is set along the width direction of the push rod, which is used to limit the displacement of the push rod in its own thickness direction and width direction, and guide the push rod to move along a predetermined trajectory.

[0057] The above technical solution has the following advantages or beneficial effects: By setting slide rails on the mutually facing sides of the drive box and push rod, and utilizing the rolling cooperation between the ball bearing bracket itself and the balls on it and the slide rails, effective limiting of the push rod in the thickness and width directions is achieved, enabling it to move smoothly along the extension direction of the slide rails. The setting of the ball bearing bracket achieves good limiting and guiding effects. Compared with the existing technology that uses several rollers to achieve limiting and form a motion trajectory, it reduces the number of parts and complexity, lowers the manufacturing cost and maintenance difficulty of the air conditioner indoor unit, improves the overall performance and reliability of the air conditioner indoor unit, and provides users with a more stable and comfortable user experience.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0081] The wall-mounted air conditioner indoor unit 100 provided in this utility model embodiment can have various implementation forms, as detailed below. Figures 1-17 The indoor unit 100 of the air conditioner is described.

[0082] It should be noted that the indoor unit 100 of the wall-mounted air conditioner is part of the air conditioner. The indoor unit 100 is installed indoors and is used for heat exchange with the indoor environment. In addition, the air conditioner also includes an outdoor unit, which is usually installed outdoors and is used to carry heat from indoors to outdoors.

[0083] refer to Figure 1 In one illustrative embodiment of the wall-mounted air conditioner indoor unit 100 provided by this utility model, the wall-mounted air conditioner indoor unit 100 may include a housing 1. The housing 1 is installed indoors, and the housing 1 forms the overall appearance of the wall-mounted air conditioner indoor unit 100.

[0084] The housing 1 is generally rectangular in shape, with its left and right ends being opposite ends along its length. The housing 1 has a top and a bottom, which are opposite ends along its height. The front and rear sides of the housing 1 are opposite sides along its thickness.

[0085] The housing 1 is located at the top of the room or in the upper space of the room. The front of the housing 1 faces the user and the rear of the housing 1 faces the wall, making it suitable for connection with the wall.

[0086] The casing 1 has an internal accommodating space. This space is used to house and fix various components in the wall-mounted air conditioner indoor unit 100, which can prevent external objects from colliding with the various components inside the casing 1, thereby improving the reliability of the wall-mounted air conditioner indoor unit 100 during transportation or installation.

[0087] In some embodiments of this application, reference is made to Figure 1 The housing 1 may include an air conditioning inlet 11.

[0088] The air conditioning inlet 11 is connected to the housing space. As the inlet for external air to flow into the casing 1, the air conditioning inlet 11 allows indoor air to enter the housing space through the air conditioning inlet 11.

[0089] In some embodiments of this application, reference is made to Figure 2 The housing 1 may include an air conditioning vent 12.

[0090] The air conditioner outlet 12 is connected to the housing space. The air conditioner outlet 12 serves as the outlet 103 for airflow to flow out of the housing 1, allowing the airflow in the housing space to flow out to the indoor environment through the air conditioner outlet 12.

[0091] The air inlet 11 can be located at the top of the housing 1. The air outlet 12 can be located on the front side of the housing 1 and near the bottom of the housing 1, that is, the air outlet 12 is located at the bottom front side of the housing 1. In this embodiment, when the indoor unit of the air conditioner is working, the indoor unit 100 takes in air from the top and exits air to the front, which is convenient for installation.

[0092] The air conditioner outlet 12 is elongated and can be extended along the length of the casing 1, which improves the aesthetics of the wall-mounted air conditioner indoor unit 100.

[0093] In some embodiments of this application, reference is made to Figure 3 The indoor unit 100 of the wall-mounted air conditioner may include an indoor heat exchanger 2.

[0094] The indoor heat exchanger 2 extends along the length of the casing 1 and is located in the housing space inside the casing 1 for heat exchange with the airflow inside the casing 1.

[0095] In some embodiments of this application, reference continues to be made to Figure 3 The indoor unit 100 of the wall-mounted air conditioner may include a heat exchange fan 3.

[0096] The heat exchange fan 3 is installed in the housing 1 and is used to drive the indoor air outside the housing 1 into the housing 1 through the air inlet. The heat exchange fan 3 drives the air in the housing to flow along the air inlet 11 toward the air outlet 12.

[0097] The heat exchange fan 3 can be a cross-flow fan, located below the indoor heat exchanger 2. To improve heat exchange efficiency, the indoor heat exchanger 2 is partially enclosed by the heat exchange fan 3, effectively increasing the heat exchange area.

[0098] The heat exchange fan 3 is positioned near the air conditioner outlet 12, while the indoor heat exchanger 2 is positioned near the air conditioner inlet 11 relative to the heat exchange fan 3. In other words, in the airflow direction within the casing 1, the heat exchange fan 3 is located downstream of the indoor heat exchanger 2.

[0099] When the indoor unit 100 of the wall-mounted air conditioner is running, driven by the heat exchange fan 3, indoor air enters the containment space through the air conditioner inlet 11. The indoor air in the containment space flows through the indoor heat exchanger 2 for heat exchange. The air after heat exchange is discharged to the outside through the air conditioner outlet 12, thereby enabling the air conditioner to cool and heat, play a role in regulating the indoor temperature, and achieve the user's comfortable temperature.

[0100] In some embodiments of this application, the wall-mounted air conditioner indoor unit 100 may include an air inlet grille 14.

[0101] The air intake grille 14 is located at the air conditioning intake 11 to prevent larger impurities from entering the containment space.

[0102] In some embodiments of this application, the indoor unit 100 of the wall-mounted air conditioner may include an air inlet filter, which is disposed between the air inlet grille 14 and the indoor heat exchanger 2 to filter indoor air and improve air quality.

[0103] An outdoor unit for an air conditioner may include an outdoor unit housing. The outdoor unit housing may contain an installation cavity.

[0104] The outdoor unit housing may include an outdoor air inlet. The outdoor air inlet may communicate with the mounting cavity. The outdoor air inlet can be used to introduce outdoor air into the mounting cavity.

[0105] The outdoor unit housing may include an outdoor air outlet. The outdoor air outlet may communicate with the mounting cavity. The outdoor air outlet can be used to exhaust air from inside the mounting cavity to the outside of the mounting cavity.

[0106] An outdoor unit for an air conditioner may include an outdoor heat exchanger. The outdoor heat exchanger may be located inside an installation cavity.

[0107] An outdoor unit for an air conditioner may include an outdoor fan. The outdoor fan may be installed inside the mounting cavity.

[0108] The rotation of the outdoor fan causes outdoor air to enter the installation cavity through the outdoor air inlet and exchange heat with the outdoor heat exchanger. After heat exchange, the outdoor air flows out of the installation cavity through the outdoor air outlet.

[0109] An air conditioner may include a compressor. The compressor is located within the mounting cavity.

[0110] Air conditioners may include a throttling device. The throttling device is used to limit airflow. The throttling device may be provided in the indoor unit 100 or the outdoor unit of a wall-mounted air conditioner.

[0111] Air conditioners execute a refrigeration cycle using a compressor, condenser, throttling device, and indoor heat exchanger. The refrigeration cycle involves a series of processes including compression, condensation, expansion, and evaporation, supplying refrigerant to the conditioned and heat-exchanged air.

[0112] The compressor compresses the refrigerant gas at low temperature and low pressure and discharges it at high temperature and high pressure. The discharged refrigerant gas flows into the condenser.

[0113] The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0114] The throttling device causes the high-temperature, high-pressure liquid refrigerant condensed in the condenser to expand into a low-pressure liquid refrigerant.

[0115] The refrigerant that expands in the throttling device evaporates in the indoor heat exchanger and returns the refrigerant gas, which is in a low-temperature and low-pressure state, to the compressor.

[0116] Indoor heat exchangers achieve a cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0117] Of the two heat exchangers, one is a condenser and the other is an indoor heat exchanger. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in heating mode. When the indoor heat exchanger is used as an indoor heat exchanger, the air conditioner is used as a cooler in cooling mode.

[0118] In some embodiments of this application, reference is made to Figure 2 , Figure 3 The wall-mounted air conditioner indoor unit 100 may include an air guide plate 13. The air guide plate 13 is movably disposed at the air conditioner outlet 12 to open or close the air conditioner outlet 12. When the air guide plate 13 opens the air conditioner outlet 12, the air guide plate 13 can be used to guide the airflow inside the casing 1.

[0119] In some embodiments of this application, the indoor unit 100 of the wall-mounted air conditioner may include a drive device connected to the air guide plate 13 to drive the air guide plate 13 to open or close the air conditioner outlet 12.

[0120] By setting up a drive device, the indoor unit of the air conditioner has the function of controlling the opening and closing of the air guide plate 13, laying the foundation for subsequent adjustment of the air supply status, facilitating flexible control of the air outlet 12, meeting different air supply needs, and improving the user experience.

[0121] Furthermore, when the air guide plate 13 opens the air outlet 12, the driving device can also drive the air guide plate 13 to rotate, guide the airflow from the air outlet 12, expand the coverage of the air supply, increase the air supply distance, which is conducive to improving the working efficiency and comfort of the air conditioner and better meeting the user's expectations for the air supply effect.

[0122] refer to Figure 2 , Figure 4 The driving device may include a push rod 5, one end of which is connected to the air guide plate 13. The push rod 5 is movable relative to the housing and is used to push out or retract the air guide plate 13.

[0123] Continue to refer to Figure 4 The driving device may include a driving box 4, which is fixedly connected to the housing. The driving box 4 has a defined receiving cavity, and a portion of the push rod 5 is disposed within the receiving cavity.

[0124] In this embodiment, the drive box 4 is fixedly connected to the housing 1, enhancing the stability of the entire drive device and providing solid support for the internal components. Simultaneously, the inclusion cavity provides a space for the push rod 5 and other components that guide and limit its movement, preventing the push rod 5 from shifting or wobbling during operation and ensuring its reliable operation.

[0125] The push rod 5 can move along its own extension direction relative to the drive box 4, so that when the push rod 5 moves, it drives the air guide plate 13 to move closer to or away from the air conditioner outlet 12. The opening and closing function of the air guide plate 13 is realized through simple linear motion. The structure is simple, easy to implement, reliable in operation, and can accurately adjust the position of the air guide plate 13.

[0126] It should be noted that during the extension and descent of push rod 5 and its retraction and ascent, it is necessary to limit its movement trajectory to ensure the stability of push rod 5. In related technologies, several rollers 43 are usually used to achieve the limiting and movement track, which cooperate with the two sides of push rod 5 to ensure that the movement trajectory of push rod 5 is a straight line or a curve.

[0127] The design and installation of multiple rollers 43 to construct the motion track complicates the structure of the entire drive unit of the air guide plate 13. The numerous rollers 43 not only increase the difficulty and time cost of assembly, but may also make it difficult to guarantee assembly accuracy, thereby affecting the overall performance and reliability of the drive unit.

[0128] In addition, during the movement of multiple rollers 43, the movement trajectory of push rod 5 may deviate due to factors such as uneven force on each roller and installation error, making it impossible to achieve high-precision positioning and guidance, thereby affecting the opening and closing accuracy of air guide plate 13 and the accuracy of air outlet direction.

[0129] To address the aforementioned technical problems, in some embodiments of this application, reference is made to... Figure 5 The drive unit may include a ball bearing support 6.

[0130] The ball bearing bracket 6 is installed between the push rod 5 and the drive box 4 to limit the push rod 5 in the thickness and width directions and form a motion trajectory in its motion direction, thus playing a guiding role in the motion of the push rod 5.

[0131] Specifically, reference Figure 8 , Figure 13 The ball bearing support 6 may include a plurality of balls 61. The plurality of balls 61 are disposed on opposite side walls of the ball bearing support 6.

[0132] The rolling axis of the ball 61 is set along the width direction of the push rod 5 so that the rolling trajectory of the ball 61 extends along the length direction of the push rod 5, i.e., the direction of movement. In other words, the ball support 6 as a whole provides limiting and supporting functions for the ball 61. The ball support 6 restricts the rotation of the ball 61 in the width direction of the push rod 5, so that the ball support 6 can limit the push rod 5 in the width direction.

[0133] Further reference Figure 8 , Figure 9 The drive box 4 has a first slide rail 46 on its mutually facing sides. (Reference) Figure 6 , Figure 9 The push rod 5 has a second slide rail 53 on its opposite sides. The second slide rail 53 is arranged opposite to the first slide rail 46 and extends along the length of the push rod 5.

[0134] In this embodiment, the ball bearing 61 is partially embedded in the first slide rail 46 and the second slide rail 53, and the ball bearing 61 rolls with the first slide rail 46 and the second slide rail 53. The rolling axis of the ball bearing 61 is set along the width direction of the push rod 5 to limit the displacement of the push rod 5 in its own thickness direction and width direction, and to guide the push rod 5 to move along a predetermined trajectory.

[0135] For details, please refer to Figure 8 The second slide rails 53 on both sides of the push rod 5 in the thickness direction cooperate with the first slide rails 46 on both sides of the drive box 4 in the thickness direction through the ball bearings 61, so that when the push rod 5 moves, the ball bearings 61 are constrained to roll in the space formed between the first slide rail 46 and the second slide rail 53.

[0136] The ball bearing 61 is in close contact with the first slide rail 46 and the second slide rail 53. When the push rod 5 tends to deviate in the thickness direction, the ball bearing 61 will exert a force on the side wall of the slide rail. The reaction force of the side wall of the slide rail on the ball bearing 61 will prevent the push rod 5 from displacing in the thickness direction, thereby limiting the push rod 5 in the thickness direction.

[0137] Furthermore, the first slide rail 46 and the second slide rail 53 can constrain the displacement of the ball 61 in the width direction of the push rod 5. The ball 61 rolls in cooperation with the first slide rail 46 and the second slide rail 53, which can not only restrict the movement of the ball 61 in the width direction of the push rod 5, but also guide the push rod 5 to move along a predetermined trajectory.

[0138] During the movement of push rod 5, if push rod 5 tends to deviate in its own width direction, ball 61 will be subjected to the reaction force from the side walls of the first slide rail 46 and the second slide rail 53, which can further prevent push rod 5 from deviating, thereby achieving the limitation of push rod 5 in the width direction.

[0139] In this embodiment, a ball bearing bracket 6 is provided between the drive box 4 and the push rod 5. The ball bearing bracket 6 itself and the balls 61 on it, in conjunction with the first slide rail 46 and the second slide rail 53, limit the thickness and width of the push rod 5 and form a motion trajectory in the direction of movement, thus guiding the movement of the push rod 5. The ball bearing bracket 6 not only effectively solves the problem of possible offset of the push rod 5 during movement, ensuring that the push rod 5 can move along a precise predetermined trajectory, but also reduces the probability of jamming, ensuring that the air guide plate 13 can accurately and smoothly open or close the air conditioning outlet 12, thereby improving the operational stability and reliability of the indoor air conditioning unit.

[0140] In some embodiments of this application, the ball bearing support 6 includes a support body, which is the main body of the ball bearing support 6 and provides a mounting and support base for the balls 61.

[0141] refer to Figure 13The support body may include a support plate 62, which is disposed on both sides of the push rod 5. The support plate 62 is provided with a plurality of through portions arranged at intervals along the movement direction of the push rod 5, and the ball bearings 61 are adapted to be connected in the through portions.

[0142] The support plate 62 serves as the mounting carrier for the ball bearing 61. By providing a through section, the ball bearing 61 is restricted by the shape of the through section when it rolls, and can only roll along the length direction of the push rod 5. This guides the push rod 5 to also move in this direction.

[0143] The support plates 62 are positioned opposite each other on both sides of the push rod 5. The push rod 5 is clamped by the rolling balls 61, which effectively prevents the push rod 5 from shaking in the thickness direction during movement and ensures that the push rod 5 moves steadily along the predetermined trajectory.

[0144] The support body may include a connecting plate 63, which is connected to two support plates 62 and together defines a semi-enclosed structure. By setting the connecting plate 63, the support plates 62 on both sides are connected into a whole, which enhances the structural stability of the ball bearing support 6, making it less prone to shaking and deformation, and better able to withstand the various forces generated when the push rod 5 moves.

[0145] The ball bearing bracket 6 with the above structure can ensure that it is stably installed between the push rod 5 and the drive box 4. The bracket body provides stable support and positioning for the ball bearing 61, ensuring that the ball bearing 61 can rotate smoothly along the movement direction of the push rod 5, thereby better playing the role of limiting and guiding, and improving the reliability and durability of the ball bearing bracket 6.

[0146] In some embodiments of this application, two first slide rails 46 are spaced apart on the side of the drive box 4 along its own width direction, and two second slide rails 53 are spaced apart on the side of the push rod 5 along its own width direction.

[0147] By setting two slides, the first slide 46 and the second slide 53, the number of contact points with the ball 61 is increased, which can more accurately limit the displacement of the push rod 5, enhance the constraint on the movement trajectory of the push rod 5, ensure that the push rod 5 will not deviate during movement, and improve the stability and accuracy of the push rod 5's movement.

[0148] The drive unit may include an ejection drive mechanism 7. (See reference) Figure 5 , Figure 6 The drive mechanism 7 is connected to the push rod 5 to drive the push rod 5 to move, so as to push out or retract the air guide plate 13.

[0149] The push-out drive mechanism 7 can precisely control the movement of the push rod 5, thereby realizing the push-out or retraction of the air guide plate 13, meeting the needs of air conditioner air outlet direction adjustment, improving the user experience, and enabling the air conditioner to flexibly adjust the air outlet direction according to different scenarios.

[0150] In some embodiments of this application, the ejection drive mechanism 7 may include an ejection motor 71, which is mounted on the drive box 4. The ejection motor 71 may be a stepper motor.

[0151] refer to Figure 4 , Figure 5 The body of the ejector motor 71 is located outside the receiving cavity, and the motor shaft of the ejector motor 71 extends through the drive box 4 into the receiving cavity.

[0152] In this embodiment, the push-out motor 71 is installed outside the drive box 4, which facilitates the installation, maintenance and management of the push-out motor 71 and provides a stable and reliable power source for the push rod 5 to push out and retract.

[0153] refer to Figure 6 The ejection drive mechanism 7 may include a gear 72, which is mounted on the motor shaft of the ejection motor 71. When the motor shaft of the ejection motor 71 rotates, it drives the gear 72 to rotate synchronously.

[0154] The push-out drive mechanism 7 may include a rack 73, which is located at the end of the push rod 5 away from the ball bearing support 6. The rack 73 extends along the length of the push rod 5 and meshes with the gear 72. When the push-out motor 71 is operating, the gear 72 and the rack 73 cooperate to drive the push rod 5.

[0155] In this embodiment, the push-out motor 71 uses gears 72 and racks 73 to drive the push rod 5 to move. The structure is simple and compact, easy to install, and has high transmission efficiency. It can accurately control the push-out and retraction of the push rod 5, which improves the smoothness and accuracy of the movement of the air guide plate 13 and meets the performance requirements of air conditioning air outlet regulation.

[0156] In some embodiments of this application, the driving device further includes a rotary driving mechanism 8. The rotary driving mechanism 8 is connected to the air guide plate 13 and is used to drive the air guide plate 13 to rotate.

[0157] By adding a rotary drive mechanism 8, the drive unit can simultaneously control the extension, retraction, and rotation of the air guide plate 13.

[0158] refer to Figure 11 The rotary drive mechanism 8 is installed on the extended end 57, making the connection between the rotary drive mechanism 8 and the air guide plate 13 more reasonable and convenient.

[0159] In this embodiment, the rotation axis of the air guide plate 13 extends along its own length direction. By driving the air guide plate 13 to rotate around its own length axis through the rotation drive mechanism 8, the air outlet angle of the air guide plate 13 can be adjusted at different angles when it is in the extended state, further improving the flexibility of the air conditioner's air outlet, meeting the diverse needs of users for air outlet direction and angle, and enhancing the practicality of the product.

[0160] In some embodiments of this application, reference is made to Figure 11 The push rod 5 may include a push rod base 51, which is mounted on the housing.

[0161] As the basic component of the push rod 5, the push rod base 51 provides support and a mounting foundation for the overall structure of the push rod 5, facilitating the installation and fixation of other components.

[0162] Continue to refer to Figure 11 The push rod 5 may include a push rod cover 52, which covers the push rod base 51. A second slide rail 53 is provided on the push rod base 51 and the push rod cover 52.

[0163] The push rod cover 52 and the push rod base 51 define an assembly cavity, which is used to accommodate the rotary drive mechanism 8.

[0164] The assembly cavity defined inside the push rod 5 provides an independent and stable space for the rotary drive mechanism 8, which is beneficial for the installation, fixation and operation of the rotary drive mechanism 8, avoids external interference during the movement of the push rod 5, and also helps to seal and protect the rotary drive mechanism 8, extend its service life and improve the stability and reliability of the entire drive device.

[0165] The rotary drive mechanism 8 is located in the assembly cavity. The drive part of the rotary drive mechanism 8 passes through the push rod base 51 and is connected to the air guide plate 13. The rotation of the drive part drives the air guide plate 13 to rotate.

[0166] In this embodiment, the push rod 5 adopts a split structure consisting of a push rod base 51 and a push rod cover 52, which not only provides installation space for the rotary drive mechanism 8, but also ensures the overall strength and stability of the push rod 5, thereby achieving stable movement of the push rod 5.

[0167] Further reference Figure 14 The rotary drive mechanism 8 may include a rotary motor 81, which provides power for the rotation of the air guide plate 13.

[0168] In some embodiments, the motor shaft of the rotary motor 81 can be a drive unit. The motor shaft of the rotary motor 81 can pass through the push rod base 51 and be directly connected to the air guide plate 13.

[0169] The motor shaft of the rotary motor 81 is directly connected to the air guide plate 13, which simplifies the transmission structure, reduces the number and complexity of intermediate transmission components, reduces the risk of failure, improves transmission efficiency and system reliability, and at the same time helps to reduce the size of the rotary drive mechanism 8 and save space.

[0170] refer to Figure 15In some embodiments, the drive mechanism 8 may include a driving gear 82 and a driven gear 83 that mesh with each other. The driving gear 82 is connected to the motor shaft of the rotary motor 81, and the drive unit is disposed on the driven gear 83.

[0171] The diameter of the driving gear 82 is smaller than that of the driven gear 83. By utilizing the meshing transmission of the driving gear 82 and the driven gear 83, torque amplification and speed adjustment can be achieved, enabling the air guide plate 13 to obtain greater torque when rotating, thus rotating more stably and adapting to different air outlet resistance conditions. At the same time, the transmission ratio of gear 72 can be adjusted as needed to achieve different rotation speed and angle control.

[0172] In some embodiments, a retaining rib 54 is provided in the push rod base 51. The retaining rib 54 is located in the assembly cavity and one end is connected to the push rod base 51, while the other end extends toward the push rod cover 52.

[0173] refer to Figure 15 A mounting plate 55 is provided on the abutment rib 54. The rotary motor 81 is mounted on the mounting plate 55. The motor shaft of the rotary motor 81 passes through the mounting plate 55 and is connected to the drive gear 82.

[0174] It should be noted that after the push rod cover 52 and the push rod base 51 are assembled, the two opposite ends of the rotary motor 81 contact the mounting plate 55 and the push rod cover 52 respectively, and the mounting plate 55 and the push rod cover 52 cooperate to complete the installation and fixation of the rotary motor 81.

[0175] In some embodiments, the body of the rotary motor 81 and the body of the push-out motor 71 are located on opposite sides of the push rod cover 52.

[0176] Positioning the bodies of the rotary motor 81 and the push-out motor 71 on opposite sides of the push rod cover 52 optimizes the spatial layout, makes the motor installation positions more reasonable, avoids mutual interference between motors, and facilitates heat dissipation and maintenance.

[0177] In some embodiments of this application, reference is made to Figure 16 A damping block 56 protrudes from the push rod 5. The damping block 56 is located on one side of the first slide rail 46 and is in contact with the drive box 4.

[0178] In this embodiment, the damping block 56 contacts the drive box 4, increasing the friction between the push rod 5 and the drive box 4, thereby offsetting part of the gravity, slowing down the speed of natural descent due to gravity, reducing the problem of jamming during the push-out process caused by the push rod 5 naturally falling faster than the push-out speed driven by the push-out drive mechanism 7, and ensuring the stability and controllability of the push rod 5 during the push-out and retraction process.

[0179] Furthermore, a damping block 56 is mounted on the push rod housing 52. (See reference) Figure 17 The push rod cover 52 is provided with a receiving portion 59 for mounting the damping block 56. The receiving portion 59 is formed by recessing the outer side of the push rod cover 52 toward the push rod base 51.

[0180] In this embodiment, the damping block 56 is set on the push rod cover 52 and installed through the receiving part 59. This ensures the stable fixation of the damping block 56 without occupying additional space, optimizes the structural layout, facilitates the installation and adjustment of the position of the damping block 56, improves the integration and compactness of the drive device, and also facilitates the maintenance and replacement of the damping block 56.

[0181] refer to Figure 16 , Figure 17 The damping block 56 is installed in the receiving part 59. The damping block 56 protrudes from the outer side of the push rod cover 52 away from the push rod base 51, so that the damping block 56 can make close contact with the drive box 4, ensuring the effective transmission of friction force. At the same time, the protruding setting helps to increase the contact area, further improve the effect of friction force, enhance the control capability of the push rod 5 movement, and ensure the smoothness and reliability of the push rod 5 movement.

[0182] In some embodiments of this application, the driver box 4 may include a box body 41. (See reference...) Figure 9 The interior of box 41 is hollow, and one side of box 41 has an opening.

[0183] The hollow box structure 41 provides installation space for push rod 5, gear 72, and rack 73. At the same time, the open design facilitates the installation and maintenance of subsequent components, improves the manufacturability and maintainability of the device, and reduces production costs and maintenance difficulty.

[0184] The drive box 4 can be covered by a cover 42, which covers the open end of the box body 41. The cover 42 and the box body 41 together define a receiving cavity and an opening 44 communicating with the receiving cavity. The opening 44 is located near the protruding end 57 for the push rod 5 to pass through.

[0185] In some embodiments, the housing 41 and the cover 42 are connected by a snap-fit ​​structure. (See reference) Figure 6 The snap-fit ​​structure may include a first snap-fit ​​part 9, which is disposed on the housing 41.

[0186] The snap-fit ​​structure may include a second snap-fit ​​portion disposed on the cover 42. The first snap-fit ​​portion 9 is adapted to the second snap-fit ​​portion to securely connect the box 41 and the cover 42.

[0187] refer to Figure 10 , Figure 11The first slide rail 46 is provided on the box body 41 and the cover body 42. The drive box 4 adopts a split structure, which facilitates the assembly of the push rod 5.

[0188] By setting the cover 42, the opening of the box 41 can be closed to form a complete receiving cavity, which provides protection for the internal push rod 5 and gear 72 and rack 73 components, preventing dust, debris and other objects from entering and operating normally. At the same time, the design of the opening 44 facilitates the insertion of the push rod 5, ensuring that the push rod 5 can smoothly extend out of the drive box 4 to realize its push-out and retraction functions, thereby improving the sealing and reliability of the drive device.

[0189] The drive box 4 can be equipped with rollers 43, which are mounted on the box body 41. (See reference) Figure 9 The rollers 43 are located on both sides of the push rod 5 in the width direction, and the rollers 43 are positioned close to the opening 44 relative to the ball bearing bracket 6.

[0190] The roller 43 provides additional support and guidance for the push rod 5, further improving the smoothness and stability of the push rod 5's movement.

[0191] The roller 43 is rollable relative to the side of the push rod 5 in the width direction, so that the push rod 5 and the two side walls of the opening 44 in the width direction of the push rod 5 are spaced apart from each other. This arrangement allows the push rod 5 to be spaced apart from the two side walls of the opening 44 during movement, thereby effectively avoiding interference between the push rod 5 and the side walls of the opening 44 during movement, ensuring the smoothness of the push rod 5 during movement, reducing noise, and reducing the frictional resistance during the movement of the push rod 5.

[0192] In some other embodiments, slides are provided on the mutually facing sides of the drive box 4 and the push rod 5. The slides extend along the length direction of the push rod 5, and multiple slides are spaced apart along the thickness direction of the push rod 5. The slide on the drive box 4 is defined as the first slide 46, and the slide on the push rod 5 is defined as the second slide 53.

[0193] refer to Figure 8 The ball bearing 61 is partially embedded in the first slide rail 46 and the second slide rail 53, and rolls with the first slide rail 46 and the second slide rail 53. The rolling axis of the ball bearing 61 is set along the width direction of the push rod 5, which is used to limit the displacement of the push rod 5 in its own thickness direction and width direction, and guide the push rod 5 to move along a predetermined trajectory.

[0194] In this embodiment, by setting slideways on the mutually facing sides of the drive box 4 and the push rod 5, and by utilizing the rolling cooperation between the ball bearing bracket 6 itself and the ball bearing 61 on it and the slideway, the push rod 5 is effectively limited in the thickness and width directions, enabling it to move smoothly along the extension direction of the slideway.

[0195] The ball bearing bracket 6 achieves good limiting and guiding effects. Compared with the existing technology that uses several rollers 43 to achieve limiting and form a motion trajectory, it reduces the number of parts and complexity, reduces the manufacturing cost and maintenance difficulty of the air conditioner indoor unit, improves the overall performance and reliability of the air conditioner indoor unit, and provides users with a more stable and comfortable user experience.
