Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more particularly to an air conditioner. Background Technology

[0002] In the field of air conditioning equipment, especially in cabinet air conditioners with air conditioning function, precise control of the air outlet direction is crucial for achieving comfortable and efficient air conditioning.

[0003] In related technologies, in order to achieve multi-angle and all-round air delivery from the air outlet, two layers of air guide plates need to be set sequentially along the front and rear directions of the cabinet unit. One layer of air guide plate swings back and forth along the width direction of the cabinet unit, and the other layer of air guide plate swings back and forth along the vertical direction of the cabinet unit.

[0004] However, the design of two air guide plates will make the air outlet structure bulky, greatly increasing the space required for the air outlet along the front and back direction of the cabinet, increasing the thickness of the cabinet, which is not conducive to the miniaturization design of the cabinet. Utility Model Content

[0005] This application discloses an air conditioner that can adjust the air outlet direction through an air outlet grille and an air guide plate installed on the air outlet grille, achieving all-round air outlet without the need for a multi-layer air guide plate structure. This can effectively reduce the space required for the air outlet of the casing along the front and rear direction of the casing, which is beneficial to the miniaturization design of the casing.

[0006] To achieve the above objectives, this application discloses an air conditioner, comprising: a cabinet unit, wherein the cabinet unit includes:

[0007] A housing, on which an air outlet is provided;

[0008] A fixed bracket is fixedly mounted on the housing and located at the air outlet;

[0009] An air outlet grille is rotatably mounted on the fixed bracket.

[0010] An air guide plate is oscillatingly mounted on the air outlet grille. When the air outlet grille rotates relative to the fixed bracket, the air outlet grille can drive the air guide plate to rotate, thereby changing the air outlet direction.

[0011] A first drive assembly is disposed on the air outlet grille and is used to drive the air guide plate to swing.

[0012] A second drive assembly, used to drive the air outlet grille to rotate, the second drive assembly includes:

[0013] A first motor is mounted on the fixed bracket;

[0014] A drive gear, which is connected to the output shaft of the first motor in a transmission manner;

[0015] A gear ring is disposed on the air outlet grille and surrounds the rotation center of the air outlet grille. The drive gear meshes with the gear ring along the axial direction of the air outlet grille.

[0016] In this way, the air outlet direction can be adjusted through the air outlet grille and the air guide plate installed on the air outlet grille, achieving all-round air outlet without the need for two or more layers of air guide plate structure. This effectively reduces the space required for the air outlet along the front and rear direction of the casing, which is conducive to the miniaturization design of the casing. Moreover, the gear ring is set on the first end face of the air outlet grille, and the drive gear and the gear ring are arranged along the axial direction of the air outlet grille and mesh with each other. This ensures that the air outlet grille can stably mesh with the drive gear, so that the air outlet grille can rotate smoothly and stably, thereby improving the reliability and service life of the air conditioning function and ensuring the accuracy and stability of the air outlet direction adjustment during long-term use of the air conditioner.

[0017] As an optional implementation, the second driving component further includes:

[0018] The gear set is used to drive the drive gear and the output shaft of the first motor. The gear set enables the drive gear to rotate at a speed greater than the output shaft of the first motor.

[0019] In this way, without increasing the speed of the first motor, the high-speed rotation of the drive gear can be achieved through the gear set transmission, making the rotational speed of the drive gear greater than the rotational speed of the output shaft of the first motor, thereby optimizing the performance of the entire drive system. This helps to meet the requirement of rapid rotation of the air outlet grille while maintaining stable motor operation, improving the efficiency and reliability of the air conditioning unit's air conditioning function.

[0020] As an optional implementation, the gear set includes:

[0021] A drive gear, which is coaxially arranged and fixedly connected to the output shaft of the first motor;

[0022] The driven gear is meshed with the driving gear, and is coaxially arranged with and fixedly connected to the driving gear. The pitch circle diameter of the driven gear is smaller than that of the driving gear.

[0023] In this way, by rationally designing the gear ratio and transmission relationship of the driving gear and driven gear, the power of the first motor can be transmitted to the drive gear more efficiently, reducing energy loss in the transmission process, improving the power transmission efficiency of the entire drive system, ensuring the smooth operation of the air conditioner's air conditioning function, and helping to reduce energy consumption.

[0024] As an optional implementation, the pitch circle diameter of the drive gear is larger than the pitch circle diameter of the driven gear.

[0025] This further accelerates the rotation speed of the gear ring, thus increasing the rotation speed of the air outlet grille, allowing for faster adjustment of the air outlet direction, meeting users' needs for rapid airflow adjustment, and improving the user experience.

[0026] In one embodiment, the drive gear is a bevel gear, the gear ring is a conical gear ring, and the axial direction of the drive gear is perpendicular to the axial direction of the gear ring.

[0027] In this way, the drive gear, as a bevel gear, can mesh better with the gear ring, enabling the drive gear to drive the gear ring to rotate and avoiding tooth jamming or tooth dislodging.

[0028] As an optional implementation, the air outlet grille includes:

[0029] An annular frame having a first surface perpendicular to its axial direction, wherein the air guide plate is rotatably disposed on the inner wall of the annular frame;

[0030] A grille, wherein the grille is disposed on the inner wall of the annular frame and arranged along the axial direction of the air outlet grille with the air guide plate;

[0031] An annular groove is provided on the first surface and is coaxial with the annular frame, and the toothed ring is provided in the annular groove;

[0032] Wherein, along the axial direction of the air outlet grille, the distance from the bottom of the annular groove to the first surface is greater than or equal to the distance from the bottom of the annular groove to the pitch circle of the gear ring.

[0033] In this way, the annular groove can effectively retain the lubricating grease between the gear ring and the drive gear, preventing the lubricating grease from leaving the drive gear and gear ring and contaminating other structural components.

[0034] As an optional implementation, the toothed ring is integrally formed with the annular frame.

[0035] In this way, the gear ring can withstand greater torque and airflow impact during the rotation of the air outlet grille, reducing the risk of deformation or damage due to weak structure, and improving product reliability and service life. Furthermore, the elimination of the need for separate installation and positioning of the gear ring avoids potential cumulative errors during assembly, ensuring precise meshing between the gear ring and the drive gear, improving assembly accuracy, simplifying assembly procedures, reducing assembly difficulty and time costs, and increasing production efficiency.

[0036] As an optional implementation, the cabinet unit further includes:

[0037] A positioning shaft is rotatably mounted on the fixed bracket and is coaxial with the annular frame;

[0038] The air outlet grille also includes:

[0039] A sleeve, the first end of which is fixedly connected to the grid plate, and the other end of which is fixedly connected to the positioning shaft, and the sleeve and the positioning shaft are coaxial.

[0040] In this way, the positioning shaft provides center positioning for the air outlet grille, making its installation position more accurate. Furthermore, the center of rotation remains stable during grille rotation, reducing wear between the sleeve and the positioning shaft, as well as between the grille and other components. Simultaneously, the stable rotational support also improves the smoothness of grille rotation, reduces noise and vibration during rotation, and enhances the overall operating quality of the air conditioner and the user experience.

[0041] As an optional implementation, the air guide plate includes:

[0042] An active air deflector is rotatably connected to the annular frame, and the axis of rotation of the active air deflector extends radially along the annular frame and passes through the center of the annular frame.

[0043] Multiple driven air vanes, all of which are arranged parallel to the active air vane and are rotatably connected to the annular frame;

[0044] The sleeve has an internal cavity for accommodating air.

[0045] The first driving component includes:

[0046] A second motor is disposed in the accommodating cavity, and the output shaft of the second motor is connected to the active air plate to drive the active air plate to swing.

[0047] A transmission link is connected to the active air vane and a plurality of driven air vanes respectively, so as to drive the plurality of driven air vanes to swing when the active air vane swings.

[0048] Thus, by placing the second motor in the cavity of the sleeve, the space inside the air outlet grille is effectively utilized, avoiding additional occupation of the external space of the cabinet unit. This helps to maintain the compactness of the overall structure of the air conditioner. Moreover, the second motor is located in the center of the air outlet grille, which prevents the second motor from rotating with the air outlet grille. This means that the position of the second motor does not need to change, which facilitates the wiring harness connection of the second motor and improves its service life.

[0049] As an optional implementation, the cabinet unit further includes:

[0050] A plurality of first rolling elements are disposed between the air outlet grille and the fixed bracket to form a rolling engagement between the air outlet grille and the fixed bracket.

[0051] In this way, the first rolling element can separate the air outlet grille from the fixed bracket and can also rotate between the air outlet grille and the fixed bracket. This can avoid static friction between the air outlet grille and the fixed bracket when the air outlet grille rotates, which would affect the rotation of the air outlet grille and allow the air outlet grille to rotate smoothly relative to the fixed bracket without jamming.

[0052] As an optional implementation, the fixing bracket has:

[0053] Mounting holes, which correspond to the air outlet, and the air outlet grille is disposed within the mounting holes;

[0054] A convex ring is provided around the inner wall of the mounting hole;

[0055] The air outlet grille has the following features:

[0056] The mounting flange is disposed on the outer peripheral wall of the air outlet grille. The mounting flange and the convex ring are opposite each other along the axial direction of the air outlet grille and have an axial gap. A plurality of first rolling elements are disposed within the axial gap.

[0057] Thus, by incorporating a first rolling element within the axial clearance, the tolerance range for assembly accuracy can be improved. Even if a certain axial error exists during assembly, the presence of the first rolling element can compensate for it to some extent. This minimizes the axial clearance between the annular frame and the fixed bracket, resulting in a more compact structure. Furthermore, it prevents direct static friction between the annular frame and the fixed bracket, which could affect the rotation of the annular frame, and allows for smoother engagement between the air outlet grille and the fixed bracket. This enhances assembly flexibility and tolerance, reduces overly stringent requirements for assembly accuracy, and helps simplify the production process and improve production efficiency.

[0058] Compared with the prior art, the beneficial effects of this application are:

[0059] The air conditioner provided in this application embodiment can adjust the air outlet direction through the air outlet grille and the air guide plate installed on the air outlet grille, achieving all-round air outlet without the need for two or more layers of air guide plate structure. This can effectively reduce the space required for the air outlet of the casing along the front and rear direction, which is conducive to the miniaturization design of the casing. Moreover, the air outlet grille is driven to rotate by the second drive component. The drive gear and gear ring of the second drive component mesh along the axial direction of the air outlet grille. This can avoid the radial tolerance of the air outlet grille affecting the normal meshing of the gear ring and the drive gear. It can also avoid the gap between the gear ring and the drive gear being too large, resulting in loose meshing and tooth skipping, or the gap between the gear ring and the drive gear being too small, resulting in tight meshing and jamming, which would affect the smooth rotation of the air outlet grille.

Detailed Implementation

[0078] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0080] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0082] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components.

[0083] In the field of air conditioning equipment, especially in cabinet air conditioners with air conditioning function, precise control of the air outlet direction is crucial for achieving comfortable and efficient air conditioning.

[0084] In related technologies, in order to achieve multi-angle and all-round air delivery from the air outlet, two layers of air guide plates need to be set sequentially along the front and rear directions of the cabinet unit. One layer of air guide plate swings back and forth along the width direction of the cabinet unit, and the other layer of air guide plate swings back and forth along the vertical direction of the cabinet unit.

[0085] However, the design of two air guide plates will make the air outlet structure bulky, greatly increasing the space required for the air outlet along the front and back direction of the cabinet, increasing the thickness of the cabinet, which is not conducive to the miniaturization design of the cabinet.

[0086] To solve the above problems, a rotatable air outlet grille can be installed at the air outlet, and a swingable air guide plate can be installed in the air outlet grille. By rotating the air outlet grille and swinging the air guide plate, multi-angle and all-round air delivery can be achieved. When the cabinet air conditioner starts the air conditioning function, the air outlet grille needs to rotate back and forth within a preset angle range to initially change the air outlet direction. At the same time, the air guide plate installed on the air outlet grille will also rotate synchronously. On this basis, in order to achieve further fine adjustment of the air outlet direction, a drive component is usually installed at the rotation axis of the air outlet grille to drive the air guide plate to swing around its own swing axis.

[0087] However, during the rotation of the air outlet grille, it needs to be connected to the drive assembly for transmission, which in turn drives the grille to rotate. The drive assembly meshes with the toothed ring on the periphery of the air outlet grille radially via a drive gear, causing the grille to rotate. However, the radial dimension of the air outlet grille is relatively large, and the diameter of the toothed ring is significantly affected by the radial tolerance of the grille. This makes it impossible to guarantee the correct spacing between the toothed ring and the drive gear along the radial direction. If the spacing is too large, the meshing is too loose, resulting in tooth skipping; conversely, if the spacing is too small, the meshing is too tight, resulting in jamming, thus affecting the smooth rotation of the air outlet grille.

[0088] Based on this, this application provides an air conditioner that can reduce the space required for the air outlet of the housing along the front-to-back direction of the housing, which is beneficial to the miniaturization design of the housing, and the air outlet grille can stably mesh with the drive gear, so that the air outlet grille can rotate smoothly and stably.

[0089] The following will refer to the embodiments and appendices. Figure 1-15 The technical solution of this application will be further explained.

[0090] Please see Figure 1 and Figure 6 , Figure 1 This is a schematic diagram of the cabinet 100 disclosed in an embodiment of this application. Figure 6This is a schematic diagram of the meshing structure between the gear ring 63 and the drive gear 62 disclosed in an embodiment of this application. This application discloses an air conditioner, including a cabinet unit 100. The cabinet unit 100 includes a housing 10, a fixed bracket 20, an air outlet grille 30, an air guide plate 40, a first drive assembly 50, and a second drive assembly 60. An air outlet 11 is provided on the housing 10. The fixed bracket 20 is fixedly disposed on the housing 10 and located at the air outlet 11. The air outlet grille 30 is rotatably mounted on the fixed bracket 20 and has a first end face 301 perpendicular to the axial direction of the air outlet grille 30. The air guide plate 40 is oscillatingly mounted on the air outlet grille 30. When the air outlet grille 30 rotates relative to the fixed bracket 20, the air outlet grille 30 can drive the air guide plate. The air outlet 11 is rotated 40 to change the air outlet direction; the first drive assembly 50 is disposed on the air outlet grille 30 and is used to drive the air guide plate 40 to swing; the second drive assembly 60 is used to drive the air outlet grille 30 to rotate, and the second drive assembly 60 includes a first motor 61, a drive gear 62 and a gear ring 63. The first motor 61 is disposed on the fixed bracket 20; the drive gear 62 is connected to the output shaft of the first motor 61; the gear ring 63 is disposed on the first end face 301 of the air outlet grille 30 and surrounds the rotation center of the air outlet grille 30. The drive gear 62 and the gear ring 63 are arranged along the axial direction a of the air outlet grille and mesh with each other.

[0091] Specifically, the cabinet 100 is a split-type air conditioner with a floor-standing indoor unit design. It is usually placed on the indoor floor, while the compressor and other refrigeration equipment are located in the outdoor unit. The indoor and outdoor units are connected by pipes and lines to work together.

[0092] The housing 10 is provided with an air outlet 11. The air outlet 11 of the housing 10 can be set on the front wall of the housing 10. The fixed bracket 20 can be fixedly installed on the front wall of the housing 10 by means of snap-fit, bolt connection or other methods. The fixed bracket 20 is located at the air outlet 11, so that the air outlet grille 30 rotatably installed on the fixed bracket 20 can be opposite to the air outlet 11, so that the air outlet grille 30 can guide the airflow sent from the air outlet 11 to the room by the cabinet 100.

[0093] Since the air outlet grille 30 can rotate on the fixed bracket 20, the air outlet grille 30 has a rotation axis. The rotation axis of the air outlet grille 30 can pass through the center of the air outlet 11. The air outlet 11 can be circular. The shape and size of the air outlet grille 30 are adapted to the air outlet 11. The axial direction of the air outlet grille 30 coincides with the axial direction of the air outlet 11.

[0094] The rotation of the air outlet grille 30 can be a reciprocating rotation, that is, rotating clockwise by a certain angle and then counterclockwise by a certain angle. The air guide plate 40 is oscillatingly mounted on the air outlet grille 30. The air guide plate 40 can rotate with the air outlet grille 30 and can oscillate back and forth. Through the rotation and oscillation of the air guide plate 40, the air outlet 11 can be changed, so that the air outlet 11 can have a multi-angle, all-round air supply effect, improve the comfort and efficiency of air conditioning, and improve the user experience.

[0095] The first drive assembly 50 is disposed on the air outlet grille 30. The first drive assembly 50 may include a second motor 51. The second motor 51 may be disposed at the center of the air outlet grille 30. The second motor 51 rotates together with the air outlet grille 30. The second motor 51 is located at the center of the air outlet grille 30, which facilitates the swinging of the air guide plate 40 while preventing the wiring harness of the second motor 51 from making circular motion with the rotation of the air outlet grille 30. This makes it easier to connect the wiring harness of the second motor 51 and improves the service life of the wiring harness.

[0096] The second drive assembly 60 can be positioned at the edge of the air outlet grille 30. The second drive assembly 60 can drive the drive gear 62 to rotate via the first motor 61, which in turn drives the gear ring 63 to rotate, ultimately rotating the air outlet grille 30. The gear ring 63 is a special type of gear with ring-shaped teeth, primarily used to transmit rotational motion. The gear ring can withstand large torques and maintain a stable transmission ratio.

[0097] Because the air outlet grille 30 needs to be adapted to the size of the air outlet 11, its radial dimension is much larger than its axial thickness. Therefore, the radial tolerance of the air outlet grille 30 is also much larger than its axial tolerance. In this embodiment, the gear ring 63 is arranged around the center of the air outlet grille 30, and the drive gear 62 and the gear ring 63 are arranged along the axial direction a of the air outlet grille and mesh with each other. The gear ring 63 is disposed on the first end face 301 of the air outlet grille 30. The axial tolerance of the air outlet grille 30 is much smaller than its radial tolerance. The actual size of the gear ring 63 is more controllable, and the meshing between the gear ring 63 and the drive gear 62 is more precise. This avoids the influence of the radial tolerance of the air outlet grille 30 on the meshing, and prevents the actual diameter of the gear ring 63 from being too large, which could cause jamming between it and the drive gear 62, or the actual diameter of the gear ring 63 from being too small, which could cause tooth skipping between it and the drive gear 62. This ensures that the air outlet grille 30 can rotate smoothly and stably, thereby improving the reliability and service life of the air conditioning function and ensuring the accuracy and stability of the air outlet direction adjustment during long-term use of the air conditioner.

[0098] According to the embodiment of the present invention, the air conditioner can adjust the air outlet direction of the air outlet 11 through the air outlet grille 30 and the air guide plate 40 installed on the air outlet grille 30, so as to achieve all-round air outlet. At the same time, it does not require the setting of two or more layers of air guide plate 40 structure, which can effectively reduce the space required for the air outlet 11 of the housing 10 along the front and rear direction of the housing 10, which is conducive to the miniaturization design of the housing 10. Furthermore, the air outlet grille 30 is driven to rotate by the second drive component 60. The drive gear 62 and the gear ring 63 of the second drive component 60 mesh along the axial direction a of the air outlet grille. This can avoid the radial tolerance of the air outlet grille 30 from affecting the meshing of the gear ring 63 and the drive gear 62. It can also avoid the gap between the gear ring and the drive gear 62 being too large, resulting in loose meshing and tooth skipping, or the gap between the gear ring and the drive gear 62 being too small, resulting in tight meshing and jamming, which would affect the smooth rotation of the air outlet grille 30.

[0099] Combination Figure 6 , Figure 7 and Figure 8 , Figure 7 This is a cross-sectional schematic diagram of the cooperation structure between the fixed bracket 20 and the air outlet grille 30 disclosed in the embodiments of this application. Figure 8 The embodiments disclosed in this application Figure 7 An enlarged structural schematic diagram at point A. In some embodiments, the second drive assembly 60 further includes a gear set 64, wherein the drive gear 62 is connected to the output shaft of the first motor 61 via the gear set 64, and the gear set 64 enables the drive gear 62 to rotate at a speed greater than the output shaft of the first motor 61.

[0100] Specifically, the gear set 64 typically includes multiple meshing gears. These gears interlock through their teeth to transmit power and change speed. In this embodiment, the gear set 64 is connected to the output shaft of the first motor 61, and the drive gear 62 is connected to the gear set 64. When the first motor 61 operates, its output shaft drives the gear set 64, which then transmits power to the drive gear 62, causing it to rotate at a certain speed, which is greater than the rotational speed of the first motor 61's output shaft. By setting the gear set 64, the rotational speed of the first motor 61's output shaft can be increased, allowing the drive gear 62 to rotate at a faster speed. This improves the response speed and flexibility of the air conditioner's airflow direction adjustment, allowing users to enjoy the air comfort effect more quickly. Furthermore, without increasing the speed of the first motor 61, the high-speed rotation of the drive gear 62 can be achieved through the transmission of the gear set 64, making the speed of the drive gear 62 greater than the speed of the first motor 61's output shaft, thereby optimizing the performance of the entire drive system. This helps to meet the need for rapid rotation of the air outlet grille while maintaining stable motor operation, thus improving the efficiency and reliability of the air conditioning unit's air conditioning function.

[0101] Combination Figure 6 , Figure 7 and Figure 8 In some embodiments, the gear set 64 includes a driving gear 641 and a driven gear 642. The driving gear 641 is coaxially arranged and fixedly connected to the output shaft of the first motor 61. The driven gear 642 is meshed with the driving gear 641, and is coaxially arranged and fixedly connected to the drive gear 62. The pitch circle diameter of the driven gear 642 is smaller than that of the driving gear 641.

[0102] Specifically, the pitch circle diameter is the reference diameter of the gear. The driving gear 641 is coaxially and fixedly connected to the output shaft of the first motor 61, so that the driving gear 641 can rotate together with the output shaft of the first motor 61 when the output shaft of the first motor 61 rotates. The driving gear 641 and the driven gear 642 are meshed through gear teeth. When the driving gear 641 rotates, it will drive the driven gear 642 to rotate in the opposite direction, realizing the transmission of power. The driven gear 642 is coaxially and fixedly connected to the driving gear 62. Their positioning axes coincide and are fixed as one unit. Therefore, the rotation of the driven gear 642 will directly drive the driving gear 62 to rotate at the same speed and direction, thereby driving the subsequent air outlet grille 30 to rotate. Since the pitch circle diameter of the driven gear 642 is smaller than that of the driving gear 641, according to the principle of gear transmission, the linear velocities of the two meshing gears are the same. Therefore, the smaller the diameter of the gear, the greater its angular velocity and the faster its rotational speed. When the driving gear 641 and driven gear 642 are meshing, the smaller pitch circle diameter of the driven gear 642 allows the driven gear 642 to rotate at a higher speed than the driving gear 641. Thus, the drive gear 62, coaxially and fixedly connected to the driven gear 62, can achieve a higher rotational speed, exceeding the rotational speed of the output shaft of the first motor 61. This drives the air outlet grille 30 to rotate rapidly, enabling rapid adjustment of the air outlet direction, improving the air conditioning unit's airflow response speed and control accuracy, and meeting the user's need for rapid changes in air outlet direction. By rationally designing the diameter ratio and transmission relationship of the driving gear 641 and the driven gear 642, the power of the first motor 61 can be transmitted to the drive gear 62 more efficiently, reducing energy loss during transmission, improving the power transmission efficiency of the entire drive system, ensuring the smooth operation of the air conditioner's air conditioning function, and helping to reduce energy consumption.

[0103] Combination Figure 6 , Figure 7 and Figure 8 In some embodiments, the pitch circle diameter of the drive gear 62 is larger than the pitch circle diameter of the driven gear 642.

[0104] Specifically, when the gear's rotational speed is constant, the gear's linear velocity is directly proportional to its pitch circle diameter. That is, assuming the gear's angular velocity remains constant, the larger the pitch circle diameter, the faster the gear's linear velocity. By making the pitch circle diameter of the driving gear 62 larger than that of the driven gear 642, the rotational speed of the gear ring 63 can be further increased during gear transmission, thus increasing the rotational speed of the air outlet grille 30. This allows for faster adjustment of the air outlet direction, meeting users' needs for quick airflow adjustment and improving the user experience.

[0105] Combination Figures 14 to 15 , Figure 14 This is a schematic diagram of the meshing between the drive gear 62 and the gear ring 63 disclosed in an embodiment of this application. Figure 15 This is a schematic diagram of the meshing of the drive gear 62 and the gear ring 63 from another angle, as disclosed in an embodiment of this application. The drive gear 62 is a bevel gear, and the gear ring 63 is a conical gear ring. The axial direction of the drive gear 62 is perpendicular to the axial direction of the gear ring 63.

[0106] Specifically, since the gear ring 63 is set on the first end face 301 of the air outlet grille 30 and surrounds the air outlet grille 30, the distance between each meshing tooth of the gear ring 63 gradually widens from the center to the edge of the gear ring 63. In order to better cooperate with the gear ring 63, the drive gear 62 in this embodiment is a bevel gear and the gear ring 63 is a conical gear ring. The drive gear 62 corresponds to and is adapted to the gear ring 63. As a bevel gear, the drive gear 62 can better mesh with the gear ring 63, which is a conical gear ring, and can drive the gear ring 63 to rotate, avoiding the phenomenon of tooth jamming or tooth dislodgement.

[0107] Combination Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the structure of the air outlet grille 30 disclosed in an embodiment of this application. Figure 4 This is a schematic diagram of the air outlet grille from another perspective of the embodiments disclosed in this application. In some embodiments, the air outlet grille 30 includes an annular frame 31, a grille plate 32, and an annular groove 33. The annular frame 31 has a first surface 302 perpendicular to its axial direction, and the air guide plate 40 is rotatably disposed on the inner wall of the annular frame 31. The grille plate 32 is disposed on the inner wall of the annular frame 31 and is arranged with the air guide plate 40 along the axial direction of the air outlet grille 30. The annular groove 33 is disposed on the first surface 302 and is coaxial with the annular frame 31, and the toothed ring 63 is disposed in the annular groove 33. Wherein, along the axial direction a of the air outlet grille, the distance from the bottom of the annular groove 33 to the first surface 302 is greater than or equal to the shortest distance from the bottom of the annular groove 33 to the pitch circle d of the toothed ring 63.

[0108] Specifically, the annular frame 31 serves as the mounting structure for the entire air outlet grille 30, providing mounting supports for the grille plate 32 and the gear ring 63. The grille plate 32 is disposed on the inner wall of the annular frame 31, forming the main structure of the air outlet grille 30 and guiding airflow through it. The gear ring 63 is disposed on the annular frame 31 and coaxial with it, meshing with the drive gear 62 along its axial direction. The gear ring 63 can be fixed to the annular frame 31 by bolts or integrally formed with the annular frame 31. During the rotation of the air outlet grille 30, it moves along the axial direction of the air outlet grille 30, such as... Figure 14 As shown, the distance from the bottom 331 of the annular groove 33 to the first surface 302 is greater than or equal to the distance from the bottom 331 of the annular groove 33 to the pitch circle d of the gear ring 63, such as... Figure 14 As shown, the distance from the bottom 331 of the annular groove 33 to the first surface 302 is L1, the distance from the bottom 331 of the annular groove 33 to the pitch circle d of the gear ring 63 is the shortest distance from the bottom 331 of the annular groove 33 to the pitch circle d of the gear ring 63, and the distance from the bottom 331 of the annular groove 33 to the pitch circle d of the gear ring 63 is L2. Wherein L1≥L2 can effectively retain the lubricating grease between the gear ring 63 and the drive gear 62, and prevent the lubricating grease from leaving the drive gear 62 and the gear ring 63 and contaminating other structural components.

[0109] In some embodiments, the toothed ring 63 is integrally formed with the annular frame 31.

[0110] Specifically, the integrated manufacturing process of the gear ring 63 and the annular frame 31 eliminates potential gaps and loosening issues during assembly, significantly enhancing the overall structural strength and rigidity of the air outlet grille 30. During rotation, the grille 30 can withstand greater torque and airflow impact, reducing the risk of deformation or damage due to structural weaknesses and improving product reliability and lifespan. Furthermore, the elimination of separate installation and positioning of the gear ring 63 avoids cumulative errors during assembly, ensuring precise meshing between the gear ring 63 and the drive gear 62, improving assembly accuracy, simplifying assembly procedures, reducing assembly difficulty and time costs, and increasing production efficiency.

[0111] Combination Figure 6 , Figure 7 and Figure 9 , Figure 9 The embodiments disclosed in this application Figure 7 Enlarged structural schematic diagram at point B. In some embodiments, the cabinet unit 100 further includes a positioning shaft 70, which is rotatably mounted on the fixed bracket 20 and coaxial with the annular frame 31; the air outlet grille 30 further includes a sleeve 34, one end of which is fixedly connected to the grille plate 32 and the other end is fixedly connected to the positioning shaft 70, and the sleeve 34 is coaxial with the positioning shaft 70.

[0112] Specifically, the positioning shaft 70 is rotatably mounted on the fixed bracket 20 and can be rotatably connected to the fixed bracket 20 via the bearing 71. The positioning shaft 70 is coaxial with the annular frame 31, providing stable support and positioning reference for the rotation of the air outlet grille 30. The sleeve 34 is fixedly connected to the grille plate 32 and also fixedly connected to the positioning shaft 70, and is coaxial with the positioning shaft 70. This allows the air outlet grille 30 to be stably installed on the fixed bracket 20 through the cooperation of the sleeve 34 and the positioning shaft 70, and to achieve smooth rotational movement. The coaxial arrangement of the positioning shaft 70 and the annular frame 31, and the fixed connection and coaxiality of the sleeve 34 to the positioning shaft 70, ensures stable support and precise positioning of the air outlet grille 30 during rotation. This avoids problems such as uneven rotation and swaying of the air outlet grille 30 caused by axial deviation or shaking, improves the rotational stability and reliability of the air outlet grille 30, and ensures the accuracy and consistency of the air outlet direction adjustment of the air conditioner. Furthermore, the fixed connection between the sleeve 34 and the grille 32, as well as the robust connection with the positioning shaft 70, enhances the overall structural strength of the air outlet grille 30. When the air outlet grille 30 rotates and withstands airflow impact, it can better disperse stress, reduce loosening and damage between components, extend the service life of the air outlet grille 30 and related components, and reduce product maintenance costs and repair frequency. It is worth noting that, because the positioning shaft 70 is coaxial with the annular frame 31, and the sleeve 34 is fixedly connected to the positioning shaft 70, the positioning shaft 70 can provide center positioning for the air outlet grille 30, making the installation position of the air outlet grille 30 more accurate. Moreover, when the air outlet grille 30 rotates, its center of rotation remains stable, reducing wear between the sleeve 34 and the positioning shaft 70, and between the air outlet grille 30 and other components. At the same time, stable rotational support also helps improve the smoothness of the air outlet grille 30's rotation, reduces noise and vibration during rotation, and improves the overall operating quality of the air conditioner and the user experience.

[0113] Combination Figure 5 , Figure 6 and Figure 13 , Figure 5 This is a schematic diagram of the cooperation structure between the fixed bracket 20 and the air outlet grille 30 disclosed in an embodiment of this application. Figure 13This is an exploded view of the fixed bracket 20 and the air outlet grille 30 disclosed in an embodiment of this application. In some embodiments, the air guide plate 40 includes an active air plate 41 and a plurality of driven air plates 42. The active air plate 41 is rotatably connected to the annular frame 31, and the axis of rotation of the active air plate 41 extends radially along the annular frame 31 and passes through the center of the annular frame 31. The plurality of driven air plates 42 are arranged parallel to the active air plate 41 and are rotatably connected to the annular frame 31. The sleeve 34 has an accommodating cavity 341 inside. The first drive assembly 50 includes a second motor 51 and a transmission link 52. The second motor 51 is disposed in the accommodating cavity 341, and the output shaft of the second motor 51 extends radially along the annular frame 31 and is connected to the active air plate 41 for driving the active air plate 41 to swing. The transmission link 52 is connected to the active air plate 41 and the plurality of driven air plates 42 respectively, so as to drive the plurality of driven air plates 42 to swing when the active air plate 41 swings.

[0114] Specifically, the active air vane 41 is rotatably connected to the annular frame 31 and extends radially along the annular frame 31, passing through the center, allowing the active air vane 41 to swing on the annular frame 31. Simultaneously, one end of the active air vane 41 is hinged to the transmission link 52, and the swinging of the active air vane 41 drives the transmission link 52 to move. Multiple driven air vanes 42 are arranged parallel to the active air vane 41 and rotatably connected to the annular frame 31. The other end of each driven air vane 42 is hinged to the transmission link 52, and the transmission link 52 drives the driven air vanes 42 to swing along with the active air vane 41. The second motor 51 is disposed in the accommodating cavity 341 of the sleeve 34, and its output shaft extends radially along the annular frame 31 and is connected to the active air vane 41. When the second motor 51 operates, the rotation of its output shaft drives the active air vane 41 to swing. The second motor 51 drives the active air vane 41 to swing, and the transmission linkage 52 drives multiple driven air vanes 42 to swing synchronously, achieving coordinated movement of the air guide vanes 40. This design allows for more efficient and precise adjustment of the air outlet direction, enabling the air conditioner to quickly respond to the user's air conditioning needs and provide a more comfortable air conditioning effect. Placing the second motor 51 within the accommodating cavity 341 of the sleeve 34 effectively utilizes the internal space of the air outlet grille 30, avoiding additional external space occupation of the cabinet unit 100 and helping to maintain the compactness of the overall air conditioner structure. Simultaneously, the parallel arrangement of the active air vane 41 and driven air vanes 42, and their rotatable connection to the annular frame 31, ensures that the air guide vane 40 assembly experiences more uniform force during swinging, improving structural stability and reliability and reducing the risk of deformation or damage due to uneven force distribution. Furthermore, the second motor 51 is located at the center of the air outlet grille 30, which avoids the second motor 51 from rotating with the air outlet grille 30. The second motor 51 only needs to rotate with the air outlet grille 30, and its position does not need to change. This facilitates the wiring harness connection of the second motor 51 and improves the service life of the second motor 51.

[0115] Combination Figure 2 , Figure 7 and Figure 10 , Figure 2 This is a schematic diagram of the structure of the fixing bracket 20 disclosed in the embodiments of this application. Figure 10 The embodiments disclosed in this application Figure 7 Enlarged structural diagram at point C. In some embodiments, the cabinet unit 100 further includes a plurality of first rolling elements 80, which are disposed between the air outlet grille 30 and the fixed bracket 20 to form a rolling engagement between the air outlet grille 30 and the fixed bracket 20.

[0116] Specifically, the air outlet grille 30 and the fixed bracket roll together when the air outlet grille rotates relative to the fixed bracket. There is no static friction between the two. Instead, they roll together through the first rolling element 80 in the middle. The first rolling element 80 can separate the air outlet grille 30 and the fixed bracket 20, and can also rotate between the air outlet grille 30 and the fixed bracket 20. This can avoid static friction between the air outlet grille 30 and the fixed bracket 20 when the air outlet grille 30 rotates, which would affect the rotation of the air outlet grille 30. This allows the air outlet grille 30 to rotate smoothly relative to the fixed bracket 20 without jamming.

[0117] In some embodiments, the fixed bracket 20 has a mounting hole 21 and a convex ring 22. The mounting hole 21 corresponds to the air outlet 11, and the air outlet grille 30 is disposed in the mounting hole 21. The convex ring 22 is disposed around the inner wall of the mounting hole 21. The air outlet grille 30 has a mounting flange 35, which is disposed around the outer peripheral wall of the air outlet grille 30. The mounting flange 35 and the convex ring 22 are opposite to each other along the axial direction of the air outlet grille 30 and have an axial gap. A plurality of first rolling elements 80 are disposed in the axial gap 110.

[0118] Specifically, the first rolling element 80 can be a ball. The convex ring 22 protrudes from the inside of the mounting hole 21 to the outside. The convex ring 22 has an annular cavity 221 that communicates with the inside of the mounting hole 21. The convex ring 22 on the inner wall of the mounting hole 21 of the fixed bracket 20 cooperates with the mounting flange 35 on the outer side of the annular frame 31 of the air outlet grille 30. The mounting flange 35 extends into the annular cavity 221 of the convex ring 22, so that the air outlet grille 30 and the fixed bracket 20 form a stable cooperative relationship. At the same time, there is an axial gap 110 between the two, which provides space for the setting of the first rolling element 80.

[0119] A first limiting groove 351 can be provided on the mounting flange 35. The first limiting groove 351 can accommodate part of the structure of the first rolling element 80, allowing the first rolling element 80 to rotate without dislodging from the first limiting groove 351. The first rolling element 80 is partially embedded in the first limiting groove 351 on the mounting flange 35 of the air outlet grille 30 and can rotate within the space where the annular cavity 221 of the convex ring 22 communicates with the first limiting groove 351. When the air outlet grille 30 rotates, the first rolling element 80 rolls between the inner wall of the convex ring 22 and the mounting flange 35, which reduces friction and supports the air outlet grille 30. The design of the first rolling element 80 being partially embedded in the first limiting groove 351 of the mounting flange 35 of the air outlet grille 30 makes the contact between the rolling element and the air outlet grille 30 and the fixed bracket 20 more compact and precise. Furthermore, the first limiting groove 351 on the mounting flange 35 cooperates with the protruding ring 22 of the fixed bracket 20 to precisely limit the position of the first rolling element 80, ensuring that the first rolling element 80 can be accurately positioned and remain stable during assembly, preventing the first rolling element 80 from coming out of the axial gap 110 between the fixed bracket 20 and the annular frame 31. This design also improves the accuracy and reliability of assembly, reduces problems such as uneven rotation or uneven force caused by the positional deviation of the first rolling element 80, and reduces the scrap rate and after-sales maintenance risks during production. The mounting flange 35 can be circumferentially mounted on the outer peripheral wall of the annular frame 31. The mounting hole 21 on the fixed bracket 20 is adapted to the outer wall of the annular frame 31 of the air outlet grille 30. The annular frame 31 of the air outlet grille 30 is inserted into the mounting hole 21 of the fixed bracket 20, and there is an axial gap 110 between them, allowing the air outlet grille 30 to rotate on the fixed bracket 20. Multiple first rolling elements 80 are disposed in the axial clearance 110, contacting the inner wall of the mounting hole 21 of the fixed bracket 20 and the outer wall of the annular frame 31 of the air outlet grille 30. When the air outlet grille 30 rotates, the first rolling elements 80 roll between the inner wall of the mounting hole 21 and the outer wall of the annular frame 31, reducing the friction between the fixed bracket 20 and the annular frame 31, ensuring smooth rotation of the annular frame 31. By setting the first rolling elements 80 in the axial clearance 110, the sliding friction between the air outlet grille 30 and the fixed bracket 20 is converted into rolling friction, greatly reducing the friction force. This not only reduces energy loss during rotation and improves the efficiency of the drive system, but also significantly reduces wear between components and extends the service life of the air outlet grille 30 and the fixed bracket 20. The rolling support effect of the first rolling elements 80 makes the rotation of the air outlet grille 30 smoother, avoiding jamming or uneven rotation caused by excessive friction. Meanwhile, multiple first rolling elements 80 are evenly distributed, providing stable support for the air outlet grille 30, ensuring that it maintains good concentricity during rotation, improving rotational stability, and making the air outlet direction adjustment more precise and stable.It is worth noting that the inclusion of a first rolling element 80 within the axial clearance 110 improves the tolerance range for assembly accuracy. Even if there is a certain axial error during assembly, the presence of the first rolling element 80 can compensate for it to some extent, minimizing the axial clearance 110 between the annular frame 31 and the fixed bracket 20, resulting in a more compact structure. This also prevents direct static friction between the annular frame 31 and the fixed bracket 20, which would affect the rotation of the annular frame 31, and allows for smoother engagement between the air outlet grille 30 and the fixed bracket 20. This enhances assembly flexibility and tolerance, reduces overly stringent requirements for assembly accuracy, and helps simplify the production process and improve production efficiency.

[0120] Combination Figure 7 and Figure 10 , Figure 10 The embodiments disclosed in this application Figure 7 An enlarged structural diagram at point C. In some embodiments, the fixed bracket 20 has a mounting hole 21, which corresponds to and is adapted to the air outlet 11. The inner wall of the mounting hole 21 is adapted to the outer wall of the annular frame 31, and there is a radial gap 120 between the inner wall of the mounting hole 21 and the outer wall of the annular frame 31 along the radial direction of the air outlet grille 30. The cabinet 100 also includes a plurality of second rolling elements (not shown in the figure), all of which are disposed in the radial gap 120.

[0121] Specifically, the mounting hole 21 on the fixed bracket 20 is adapted to the outer wall of the annular frame 31 of the air outlet grille 30. The annular frame 31 of the air outlet grille 30 is inserted into the mounting hole 21 of the fixed bracket 20, with a radial gap 120 between them, allowing the air outlet grille 30 to rotate on the fixed bracket 20. Multiple second rolling elements are disposed in the radial gap 120, contacting the inner wall of the mounting hole 21 of the fixed bracket 20 and the outer wall of the annular frame 31 of the air outlet grille 30. When the air outlet grille 30 rotates, the second rolling elements roll between the inner wall of the mounting hole 21 and the outer wall of the annular frame 31, reducing the friction between the fixed bracket 20 and the annular frame 31, ensuring smooth rotation of the annular frame 31. By providing second rolling elements in the radial gap 120, the sliding friction between the air outlet grille 30 and the fixed bracket 20 is converted into rolling friction, significantly reducing friction. This not only reduces energy loss during rotation and improves the efficiency of the drive system, but also significantly reduces wear between components, extending the service life of the air outlet grille 30 and the fixed bracket 20. The rolling support of the second rolling element makes the rotation of the air outlet grille 30 smoother, avoiding jamming or uneven rotation caused by excessive friction. Simultaneously, the even distribution of multiple second rolling elements provides stable support for the air outlet grille 30, ensuring good concentricity during rotation, improving rotational stability, and making airflow direction adjustment more precise and stable. It is worth noting that the inclusion of the second rolling element in the radial clearance 120 increases the tolerance range of assembly accuracy. Even if there is a certain radial error during assembly, the presence of the second rolling element can compensate for it to some extent, minimizing the radial clearance 120 between the annular frame 31 and the fixed bracket 20, making the structure more compact. It also avoids direct static friction between the annular frame 31 and the fixed bracket 20, which would affect the rotation of the annular frame 31, and allows for smoother cooperation between the air outlet grille 30 and the fixed bracket 20. This improves assembly flexibility and tolerance, reduces overly stringent requirements for assembly accuracy, and helps simplify the production process and improve production efficiency.

[0122] Combination Figure 7 and Figure 10 , Figure 10 The embodiments disclosed in this application Figure 7 Enlarged structural schematic diagram at point C. In some embodiments, the air outlet grille 30 has a plurality of second limiting grooves (not shown in the figure), which are arranged around the outer periphery of the annular frame 31, and each second rolling element is partially embedded and rotatably disposed in the second limiting groove.

[0123] Specifically, the second rolling element can be a ball bearing. Multiple second limiting grooves are provided on the outer wall of the annular frame 31 of the air outlet grille 30. The second rolling element is partially embedded in these second limiting grooves and can rotate within them. This creates a tight fit between the second rolling element and the air outlet grille 30, while allowing the rolling element to rotate freely when the air outlet grille 30 rotates. The outer side of the second rolling element contacts the inner wall of the mounting hole 21 of the fixed bracket 20. When the air outlet grille 30 rotates, the rolling element can roll within the radial gap 120 between the inner wall of the mounting hole 21 and the outer wall of the annular frame 31, reducing friction and supporting the air outlet grille 30. The partial embedding of the second rolling element in the second limiting groove of the air outlet grille 30 makes the contact between the rolling element and the air outlet grille 30 and the fixed bracket 20 more compact and precise. When the air outlet grille 30 rotates, the rolling element can more effectively convert sliding friction into rolling friction, further reducing friction and wear, and improving the smoothness of the rotation and service life of the air outlet grille 30. Multiple second rolling elements can be evenly distributed on the outer periphery of the annular frame 31 and embedded in the second limiting groove, forming a stable support structure. This not only improves the stability of the air outlet grille 30 during rotation, reducing swaying and vibration, but also increases the load-bearing capacity of the air outlet grille 30 to a certain extent, enabling it to withstand greater torque and airflow impact without easily deforming or being damaged, ensuring the stability and reliability of the air conditioning function. Moreover, the second limiting groove on the annular frame 31 cooperates with the mounting hole 21 of the fixed bracket 20 to precisely limit the position of the second rolling elements, ensuring that the second rolling elements can be accurately positioned and remain stable during assembly, preventing the second rolling elements from coming out of the radial gap 120 between the fixed bracket 20 and the annular frame 31.

[0124] Combination Figure 1 In some embodiments, the cabinet unit 100 also includes a panel 90, which is disposed at the front of the housing 10, and an air outlet 11 is disposed on the panel 90. A fixing bracket 20 is detachably connected to the air outlet 11 of the panel 90.

[0125] Specifically, panel 90 is located at the front of housing 10. It not only serves a decorative purpose but also conceals and protects internal components, while also serving as the mounting base for bracket 20. Bracket 20 is detachably mounted on panel 90. This detachable connection method can be a common mechanical connection such as screws or clips, facilitating easy disassembly and installation when needed. Because bracket 20 is detachably mounted on panel 90, it can be easily removed during air conditioner installation or maintenance, making it easier to access the air outlet grille 30 and other related components. This design reduces the difficulty of maintenance and repair, improves maintenance efficiency, and reduces repair time and costs. Furthermore, compared to mounting bracket 20 on the inner wall of the internal air guide housing, it avoids the bracket 20 affecting the air outlet structure of the air guide housing, ensuring the sealing performance of the air guide housing.

[0126] Combination Figure 11 and Figure 12 , Figure 11 This is a schematic cross-sectional view of the cabinet 100 disclosed in an embodiment of this application. Figure 12 The embodiments disclosed in this application Figure 11 The diagram shows a partial structural design of the unit. In some embodiments, the cabinet unit 100 further includes a first cross-flow air duct 1011, a second cross-flow air duct 1012, and a partition 1013. The second cross-flow air duct 1012 is arranged side by side with the first cross-flow air duct 1011. The partition 1013 is located between the outlet of the first cross-flow air duct 1011 and the outlet of the second cross-flow air duct 1012. The fixed bracket includes a fixed frame 25 and a mounting plate 23. The two ends of the mounting plate 23 are respectively connected to opposite sides of the fixed frame 25 along the radial direction. The positioning shaft 70 is rotatably mounted on the mounting plate 23. Along the axial direction of the air outlet grille 30, the mounting plate 23 can cover the partition 1013.

[0127] Specifically, the dual-flow duct design increases the air volume and distance of the duct. The middle partition 1013 helps to evenly guide the airflow to both sides or different directions. Combined with the rotation and oscillation of the air outlet grille 30, it makes the air supply of the air conditioner more uniform and efficient, covering a larger space and improving the air conditioning effect. The fixed frame 25 can be an annular frame, and the mounting plate 23 is set on the fixed frame 25. The centers of the fixed frame 25, the air outlet 11, and the annular frame 31 are located at the same position. The mounting plate 23 extends radially along the fixed frame 25 and passes through the center of the fixed bracket 20. The setting of the mounting plate 23 can provide a stable support structure for the fixed frame 25, making the entire fixed bracket 20 structure more stable. This makes the rotation of the air outlet grille 30 within the fixed bracket 20 smoother, helping to reduce the shaking and friction of mechanical parts during operation, further reducing noise levels and improving the operating quality of the air conditioner. Furthermore, the mounting plate 23 can block the partition 1013 along the axial direction of the air outlet grille 30. This compact layout makes full use of the internal space of the cabinet unit 100, avoids wasting space, makes the structure of the entire air conditioner more compact, and does not block the outlet of the first cross-flow air duct 1011 and the second cross-flow air duct 1012, thus avoiding affecting the air outlet of the first cross-flow air duct 1011 and the second cross-flow air duct 1012. This helps to improve space utilization and reduce the size of the cabinet unit 100.

[0128] Combination Figure 11 and Figure 12 In some embodiments, the cabinet unit 100 further includes an air guide housing 101, which forms a first cross-flow air duct 1011 and a second cross-flow air duct 1012. The air guide housing 101 also has an end plate 1014 that is opposite to the air outlet 11 along the axial direction of the air outlet grille 30. The outlets of the first cross-flow air duct 1011 and the second cross-flow air duct 1012 are both opened on the end plate 1014. The fixed bracket 20 also has a sealing flange 24, which is arranged around the periphery of the fixed bracket 20. The sealing flange 24 and the end plate 1014 are fitted together along the axial direction of the air outlet grille 30.

[0129] Specifically, the air guide housing 101 forms the first cross-flow air duct 1011 and the second cross-flow air duct 1012 of the air conditioner, with a partition 1013 extending vertically in the middle, so that the airflow can be evenly guided to both sides. The air guide housing 101 has an end plate 1014 that is axially opposite to the air outlet grille 30, providing an installation and sealing reference surface for the air outlet 11. The fixed bracket 20 is fixedly mounted on the panel 90. The fixed bracket 20 is not directly connected to the air guide housing 101 to avoid affecting the air guiding performance of the air guide housing 101 due to its installation structure. After the fixed bracket 20 is installed on the panel 90, its sealing flange 24 fits snugly against the end plate 1014 of the air guide housing 101, forming a complete sealing surface. This ensures that airflow will not leak from the gap between the fixed bracket 20 and the air guide housing 101, improving the sealing performance between them. Airflow can then smoothly enter the outlet grille 30, reducing flow resistance, improving air delivery efficiency, and reducing airflow leakage and eddy noise. Simultaneously, it stabilizes the structure, reducing vibration noise and improving operational quietness. A sealing sponge can also be placed between the sealing flange 24 and the end plate 1014 of the air guide housing 101 to further improve the sealing effect of the sealing flange 24.
