Air conditioner indoor unit and air conditioner

Abstract

The application provides an air conditioner indoor unit and an air conditioner, and relates to the technical field of air conditioner structures. The air conditioner indoor unit comprises a shell, an air outlet air duct and a guide vane. According to the application, a fixed section is arranged on the top wall of the air outlet air duct, and a rotating section is rotatably connected with the fixed section. When the guide vane rotates in the air outlet air duct, the guide vane drives the free end of the rotating section to rotate to avoid the rotation of the guide vane, so that the guide vane can rotate in a larger range and air can be supplied at a large angle. At the same time, since the rotating section is driven to rotate by the guide vane, a rotating section driving motor is not needed, which is beneficial to reducing the number of driving motors and improving the compactness of the structure of the air conditioner indoor unit. In addition, in the application, the rotating section of the air outlet air duct avoids the guide vane, so that the size of the guide vane in the air outlet direction is larger, which is beneficial to improving the air supply distance and the air supply range.

Description

Technical Field

[0001] This application relates to the field of air conditioner technology, specifically to an indoor air conditioner unit and an air conditioner. Background Technology

[0002] An air conditioner is an appliance used to regulate indoor temperature. Based on the principle of thermal expansion and contraction, cold air is denser. When cooling, the air deflector of the indoor unit should be at a small angle to the horizontal as much as possible. Under the influence of gravity, the cold air slowly sinks, lowering the indoor temperature. The perceived airflow is less noticeable during cooling, improving comfort. When heating, the air deflector should be at a larger angle to the horizontal as much as possible. Under the buoyancy force generated by the density difference, the hot air rises, raising the indoor temperature and achieving "carpet-like" airflow, further enhancing comfort.

[0003] The air deflector of a conventional wall-mounted air conditioner indoor unit has a limited range of rotation angles due to space constraints at the air outlet. Therefore, it requires multiple motors and levers to control the deflector, ensuring that the airflow maintains a small angle between the cold air and the horizontal direction during cooling mode, while allowing the hot airflow to maintain a larger angle between the cold air and the horizontal direction during heating mode. However, this drive system using multiple motors and levers is complex and increases product cost. Summary of the Invention

[0013] Optionally, the air guide plate has a first position, and when the air guide plate is in the first position, the air guide plate closes the air outlet;

[0014] And / or, the air guide plate has a second position; when the air guide plate is in the second position, the air outlet direction tends to be vertical.

[0015] Optionally, during the process of the air guide plate rotating from the first position to the second position, the air guide plate has a third state of abutting against the rotating section and a fourth state of disengaging from the rotating section;

[0016] When the air guide plate is in the third state, the rotating section is in the avoidance state;

[0017] When the air guide plate is in the fourth state, the rotating section is in the initial state.

[0018] Optionally, when the air guide plate is in the first position, the rotating section is in the initial state;

[0019] The free end extends to the upper edge of the air outlet; the air guide plate includes a first end and a second end disposed opposite to each other, the first end extending to the side of the free end near the air outlet, and the second end near the lower edge of the air outlet;

[0020] During the process of the first end rotating into the air outlet duct, the first end drives the free end to rotate to avoid the rotation of the air guide plate.

[0021] Optionally, when the air guide plate is in the second position, the end of the air guide plate near the top wall is close to the end of the fixed section away from the fan.

[0022] Optionally, the air guide plate is provided with a guide member, which is used to guide the relative movement between the air guide plate and the rotating section when the air guide plate rotates and abuts against the rotating section.

[0023] Optionally, the guide includes a sliding surface disposed at the end of the air guide plate.

[0024] Optionally, the guide includes a rolling element that is rotatable relative to the air guide plate, and the rolling surface of the rolling element protrudes from the end face of the air guide plate.

[0025] Optionally, the rotating section is located on the side of the fixed section opposite to the air outlet duct;

[0026] When the rotating segment is in the initial state, the connecting end is supported on the fixed segment, and the connecting end is arranged parallel to the fixed segment.

[0027] Optionally, the housing further includes a limiting member disposed on the upper edge of the air outlet and extending into the air outlet;

[0034] The air conditioner indoor unit provided in this application embodiment has a fixed section and a rotating section rotatably connected to the fixed section on the top wall of the air outlet duct. When the air guide plate rotates within the air outlet duct, the free end of the rotating section is driven to rotate to avoid the rotation of the air guide plate, thereby enabling the air guide plate to rotate over a large range and achieve large-angle air delivery. Simultaneously, since the rotating section is driven by the air guide plate, a separate drive motor for the rotating section is not required, reducing the number of drive motors, which helps reduce manufacturing costs and improves the structural compactness of the air conditioner indoor unit. Furthermore, in this application, because the rotating section of the air outlet duct avoids the air guide plate, the size of the air guide plate along the air outlet direction is larger, which helps to increase the air delivery distance and air delivery range of the air conditioner indoor unit.

[0056] 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 a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0057] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0058] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0059] This application provides an indoor air conditioning unit and an air conditioner to solve the problem that the limited rotation angle of the air guide plate in existing indoor air conditioning units restricts the airflow direction, thus affecting user comfort. Exemplarily, the indoor air conditioning unit in this application can be a wall-mounted unit, or other air conditioners with the same or similar problems, and is not limited thereto. The following will use a wall-mounted unit as an example and provide a detailed description in conjunction with the accompanying drawings.

[0060] Please see Figure 1 The wall-mounted air conditioner indoor unit 1 provided in this application embodiment includes a housing 10, an air guide assembly 20, and an air outlet duct 50.

[0061] An installation cavity (not shown in the figure) is formed within the housing 10, which provides installation space for components such as the heat exchanger and the fan 60. The housing 10 has an air inlet (not shown in the figure) and an air outlet 10a. An air outlet duct 50 connecting the air inlet and the air outlet is located within the housing 10. When the indoor unit 1 of the air conditioner is working, driven by the fan 60, air flows in from the air inlet, is heated by the heat exchanger, enters the air outlet duct 50, and flows out of the housing 10 through the air outlet 10a.

[0062] The housing 10 can be of any shape, such as square, cylindrical, or prismatic, and is not limited thereto. Specifically, in this application, the housing 10 is generally square, with the air outlet 10a located at the lower left of the housing 10 and the air inlet located at the top of the housing 10. Of course, in some other embodiments of this application, the housing 10 may also be of other shapes.

[0063] The air guiding assembly 20 includes an air guiding plate 21. The air guiding plate 21 is rotatably disposed at the air outlet 10a and is used to adjust the air outlet 10a's airflow direction.

[0064] It should be noted that when the indoor unit 1 is not in operation, the air guide plate 21 is generally closed over the air outlet 10a of the housing 10. To improve the aesthetics and sealing effect of the housing 10, the size of the existing air guide plate 21 is adapted to the size of the air outlet 10a. Simultaneously, to increase the airflow and air distribution range of the indoor unit, the end of the air outlet duct 50 (i.e., the end closest to the air outlet) needs to extend to the air outlet 10a. Furthermore, along the air outlet direction of the air outlet duct 50 (i.e., the direction of airflow within the air outlet duct), the size of the air outlet duct 50 gradually increases, such as... Figure 1 The air guide plate 21 has a horn-shaped structure. Therefore, when the air guide plate 21 rotates, it is easily restricted by the outer shell 10 or the air outlet duct 50, resulting in a small rotation angle of the air guide plate 21 and poor comfort.

[0065] In the prior art, to increase the rotation angle of the air guide plate 21, one solution is to install a swing mechanism on the indoor unit. Another solution is to reduce the width dimension of the air guide plate (i.e., the dimension along the line connecting the bottom and top walls).

[0066] The main principle of the swing mechanism design is to swing the air guide plate a certain distance from the air outlet, creating a gap between the air guide plate and the casing. This gap provides clearance for the air guide plate to rotate, allowing it to reach a suitable air delivery position and achieve a large-angle airflow. However, this design results in a complex structure for the indoor unit and requires a separate motor to drive the swing mechanism, significantly increasing the cost of the air conditioner.

[0067] The solution of reducing the size of the air guide plate in the indoor unit of the air conditioner results in a large gap between the air guide plate and the air outlet wall when the air conditioner is not working. This leads to poor aesthetics and sealing of the air conditioner, and dust can easily enter the interior of the indoor unit through the gap. In addition, the reduced size of the air guide plate results in a shorter air delivery distance and insufficient air delivery range.

[0068] In view of the shortcomings of the prior art, the air outlet duct 50 of this application includes a top wall 51 and a bottom wall 52 disposed opposite to each other. The top wall includes a fixed section 511 and a rotating section 512 disposed along the air outlet direction. The rotating section includes a free end 5121 and a connecting end 5122 rotatably connected to the fixed section. When the air guide plate 21 rotates within the air outlet duct 50, the air guide plate 21 drives the free end 5121 to rotate to avoid the rotation of the air guide plate 21.

[0069] Compared with the prior art, this application designs the top wall 51 of the air outlet duct as a fixed section 511 and a rotating section 512 arranged along the air outlet direction. The rotation of the rotating section 512 allows the size of the side of the air outlet duct 50 near the air outlet 10a to be adjusted within a certain range, thus providing clearance for the rotation of the air guide plate 21 within the air outlet duct 50. This allows the air guide plate 21 to rotate over a larger angle, achieving wide-angle air delivery. Simultaneously, since the rotating section 512 is driven by the air guide plate 21, a separate drive motor for the rotating section is not required, reducing the number of drive motors and simplifying the air conditioner's structure, thus reducing the size of the indoor unit. Furthermore, because the rotating section 512 of the air outlet duct avoids the air guide plate 21, the size of the air guide plate along the air outlet direction is larger, which helps to increase the air delivery distance and range of the air conditioner's indoor unit.

[0070] The rotating section 512 includes a free end 5121 and a connecting end 5122. In some embodiments of this application, the connecting end 5122 is rotatably connected to the fixed section 511, and the free end 5121 is located near the air outlet. In other embodiments of this application, the connecting end 5122 may be located near the air outlet and rotatably connected to the housing 10, with the free end 5121 extending to the fixed section 511 and sealingly connected to it.

[0071] For example, the fixed section 511 extends from the volute tongue toward the air outlet. The ratio of the length of the fixed section 511 to the length of the top wall is between 0.2 and 0.5. This structure can provide a larger clearance space when the rotating section rotates, which is beneficial to increasing the rotation angle and size of the air guide plate 21, thereby further increasing the air delivery distance.

[0072] In some embodiments of this application, the rotating segment 512 has an initial state and a clearance state. When the rotating segment 512 is in the initial state, the rotating segment 512 seals the gap 12 between the fixed segment 511 and the upper edge of the air outlet. When the rotating segment 512 is in the clearance state, the rotating segment 512 is located above the upper edge of the air outlet (i.e., the top wall of the air outlet).

[0073] Specifically, please refer to Figure 1 and Figure 2 , Figure 1 and Figure 2 A schematic diagram of the rotating section in its initial state is shown. When the rotating section 512 is in its initial state, the connecting end 5122 of the rotating section 512 is sealed to the end of the fixed section 511 near the air outlet 10a, and the free end 5121 of the rotating section 512 extends to the upper edge of the air outlet 10a and is sealed to the inner wall of the housing. This embodiment allows all the airflow flowing out of the air outlet duct to exit the room through the air outlet, which is beneficial for increasing the air volume of the indoor unit of the air conditioner.

[0074] Please see Figure 2 and Figure 3 , Figure 3A schematic diagram of the rotating section in a avoidance state is shown. Exemplarily, the air guide plate 21 rotates towards the air outlet duct (i.e., clockwise in the figure). The air guide plate 21 includes a first end 21a (i.e., the end of the air guide plate near the top wall) and a second end 21b disposed opposite to each other. The first end 21a of the air guide plate abuts against the rotating section 512, and during rotation, the first end 21a drives the free end 5121 to rotate in a direction away from the air outlet 10a to avoid the rotation of the air guide plate 21. Of course, in other embodiments of this application, the air guide plate 21 may also drive the rotating section 512 to rotate in a counterclockwise direction within the air outlet duct to avoid the rotation of the air guide plate 21. Correspondingly, the second end 21b of the air guide plate abuts against the rotating section 512, and during rotation, the second end 21b drives the free end 5121 to rotate in a direction away from the air outlet 10a to avoid the rotation of the air guide plate 21. This is not limited here.

[0075] In some embodiments of this application, the air guide plate 21 has a first position, which, exemplarily, is the position when the indoor unit of the air conditioner is not working. When the air guide plate is in the first position, the air guide plate 21 closes the air outlet 10a.

[0076] Specifically, please refer to [the relevant document] again. Figure 1 , Figure 5 and Figure 8 , Figure 1 A schematic diagram of the structure of the air guide plate 21 in the first position is shown. The orthographic projection of the air guide plate 21 is generally a long plate structure, and the cross-section of the air guide plate 21 is an arc-shaped structure. The convex surface of the air guide plate 21 faces the outside of the housing. The second end 21b of the air guide plate extends to the lower edge of the air outlet 10a (that is, the bottom wall of the air outlet), and the first end 21a of the air guide plate extends to the upper edge of the air outlet, thereby minimizing the gap between the air guide plate 21 and the upper and lower edges of the air outlet 10a, which is beneficial to improving the aesthetics and sealing effect of the housing 10.

[0077] In one embodiment, a second rotating shaft 211 may be provided on the side of the air guide plate 21 facing the inside of the housing 10. The end of the second rotating shaft 211 is rotatably connected to the housing 10, and the air guide plate 21 achieves relative rotation with the housing 10 through the second rotating shaft 211.

[0078] Furthermore, please refer again. Figure 1When the air guide plate 21 is in the first position, the rotating section 512 is in the initial state. The free end 5121 extends to the upper edge of the air outlet 10a. The first end 21a of the air guide plate extends to the side of the free end near the air outlet, and the second end 21b of the air guide plate is near the lower edge of the air outlet. In this embodiment, since the free end can rotate, there will be no rigid collision between the free end and the housing at the upper edge of the air outlet, and between the free end and the air guide plate (first end). This allows the gap between the free end and the housing, and the gap area between the free end and the air guide plate (first end) to be 0, which is beneficial to improving the sealing performance and structural compactness of the air conditioner indoor unit. In addition, when the indoor unit drives the air guide plate to rotate into the air outlet duct, the free end can rotate synchronously with the air guide plate. At this time, the distance between the end of the air guide plate and the rotating section that abuts is the farthest from the junction point, and the resistance force exerted by the rotating plate on the air guide plate is minimal, which is beneficial to improving the stability of the air conditioner indoor unit when starting up.

[0079] Please refer to some embodiments of this application. Figure 2 The air guide plate 21 has a second position, which, exemplarily, is the position of the air guide plate 21 when the indoor unit 1 of the wall-mounted air conditioner is in heating mode. When the air guide plate 21 is in the second position, the air outlet 10a tends to be vertical.

[0080] It should be noted that in this application, the air outlet direction is considered to be vertical, meaning the angle between the air outlet direction and the horizontal plane is between 80° and 100°. Wall-mounted air conditioner indoor units are generally installed in indoor spaces where the floor is horizontal; therefore, the verticality of the air outlet direction can also be considered as the angle between the air outlet direction and the floor being between 80° and 100°. In other words, the verticality of the air outlet direction can also be considered as the angle between the air outlet direction and the direction of gravity (i.e., vertically downward) being within 10°.

[0081] In some embodiments of this application, when the air guide plate 21 is in the second position, the first end 21a of the air guide plate is close to the end of the fixed section 511 that is away from the fan 60. Specifically, the cross-section of the fixed section 511 is generally an inclined straight line, and this straight line largely coincides with the tangent L of the first end 21a of the air guide plate. This structure helps to reduce the wind resistance and vibration noise of the air outlet duct while achieving vertical air outlet.

[0082] Please refer to it again. Figures 1 to 3 In some embodiments of this application, during the process of the air guide plate 21 rotating from the first position to the second position, the air guide plate 21 has a third state of abutting against the rotating section 512 (e.g., Figure 3 (as shown in the diagram) and the fourth state (as shown in the diagram) where it is disengaged from the rotating section 512. Figure 2(As shown in the diagram). When the air guide plate 21 is in the third state, the rotating section 512 is in the avoidance state. When the air guide plate 21 is in the fourth state, the rotating section 512 is in the initial state. This embodiment enables all the airflow after heat exchange to flow out through the air outlet of the air outlet duct and to be discharged vertically under the action of the air guide plate, thereby improving airflow and comfort.

[0083] Understandably, during the process of the air guide plate 21 rotating from the first position to the second position, the first end 21a of the air guide plate first abuts against the free end 5121 to drive the free end to rotate. As the air guide plate 21 continues to rotate clockwise, the contact point between the first end 21a of the air guide plate and the rotating plate 512 moves along the surface of the rotating plate and continuously towards the connecting end 5122. When the first end 21a of the air guide plate 21 rotates to the highest point (e.g., ... Figure 3 At the highest position, the free end 5121 of the rotating section reaches its maximum rotation angle. Afterward, the first end 21a continues to rotate clockwise past the highest point, with the free end 5121 rotating towards the air outlet 10a. When the first end 21a passes the highest point and rotates towards the second position, it disengages from the rotating section 512, returning to its initial state. After disengaging from the rotating section 512, the first end 21a continues to rotate clockwise to the second position, thus making the air outlet direction of the indoor unit of the air conditioner tend to be vertical.

[0084] Please see Figure 4 The air guide plate 21 also has a third position. For example, the third position is the position of the air guide plate 21 when the indoor unit 1 of the wall-mounted air conditioner is in the cooling state. When the air guide plate 21 is in the third position, the air guide plate 21 makes the air outlet 10a tend to be horizontal.

[0085] It should be noted that in this application, the air outlet direction tends to be horizontal, meaning that the angle between the air outlet direction and the horizontal plane is within 10 degrees. For example, the air outlet direction can be upward to the left, with the angle between the air outlet direction and the left side being within 10 degrees; or the air outlet direction can be downward to the left, with the angle between the air outlet direction and the left side being within 10 degrees.

[0086] It is understood that the rotational connection between the rotating section 512 and the fixed section 511 can be, but is not limited to, a hinge or a shaft rotational connection. Please refer to the following: Figure 5 and Figure 6 For example, the connecting end 5122 of the rotating section is provided with a first rotating shaft 513, and the end of the first rotating shaft 513 is rotatably connected to the fixed section 511. The rotating section 512 achieves relative rotation with the fixed section 511 through the first rotating shaft 513. Figure 5As shown, the connecting end 5122 of the rotating section can be located on the side of the fixed section 511 away from the air outlet duct. In this case, the fixed section 511 also serves to support and limit the rotation section 512. Figure 6 As shown, the connecting end 5122 of the rotating section can also be directly rotatably connected to the end of the fixed section 511, so that when the rotating section 512 is in the initial position, the rotating section 512 and the fixed section 511 are spliced ​​together to form a continuous air outlet duct, which helps to reduce the resistance of the air outlet duct and increase the air volume.

[0087] Specifically, please refer to Figure 1 and Figure 7 The rotating section 512 is located on the side of the fixed section 511 opposite to the air outlet duct 50. This structural arrangement helps improve the stability of the air outlet duct 50 and reduce its resistance. When the rotating section 512 is in the initial state, the connecting end 5122 is supported on the fixed section 511, and the connecting end 5122 is substantially parallel to the fixed section 511. Furthermore, the width of the contact surface between the rotating section 512 and the fixed section 511 (i.e., the width of the overlapping portion) is L2, where L2 ≥ 10 mm, so that the fixed section 511 provides stable support and limiting for the rotating section 512.

[0088] In some embodiments of this application, the air guide assembly 20 further includes a guide member 22. The guide member 22 is used to guide the relative movement between the air guide plate 21 and the rotating section 512 when the air guide plate 21 rotates and abuts against the rotating section 512.

[0089] Specifically, please refer to Figure 5 and Figure 8 The first end 21a of the air guide plate 21 is provided with a guide member 22. When the air guide plate 21 rotates between the first position and the second position, the guide member 22 can abut against the rotating section 512. The contact between the guide member 22 and the rotating section 512 is a point contact or a line contact, thereby reducing the resistance between the air guide plate 21 and the rotating section 512 during the rotation process, making the air guide plate 21 rotate more smoothly and stably.

[0090] Please see Figure 8 To further improve the stability of the air guide plate 21 when rotating between the first and second positions, at least two guide members 22 may be provided, with the at least two guide members 22 evenly spaced at the ends of the air guide plate 21. For example, the number of guide members 22 is five, and the five guide members 22 are evenly spaced along the length direction of the air guide plate 21.

[0091] It is understood that the guide member 22 can rotate relative to the air guide plate 21, or it can remain relatively fixed relative to the air guide plate 21. This application embodiment does not limit this.

[0092] Please see Figures 8 to 10 In some embodiments, the guide member 22 includes a rolling element 221 disposed at a first end. Exemplarily, the rolling element 221 can be a roller or a ball. The rolling element 221 protrudes from the end face of the first end of the air guide plate 21. The rolling element 221 is rotatably connected to the air guide plate 21 via a connecting shaft (not shown), allowing the rolling element 221 to roll relative to the air guide plate 21, further reducing the resistance between the air guide plate 21 and the rotating section when the air guide plate 21 rotates.

[0093] Please see Figure 7 In one embodiment, the distance between the end of the rolling element 221 away from the air guide plate 21 and the end face of the air guide plate 21 is L1, where L1 ≥ 0.5 mm. This ensures that the rolling element 221 and the rotating section can maintain relative rotation while minimizing the gap between the air guide plate 21 and the rotating section, which is beneficial to ensuring the concentration of airflow when it is blown out of the air outlet 10a.

[0094] In some embodiments of this application, the guide member 22 can be a sliding surface (not shown in the figure) disposed at the first end, and the sliding surface can also be an arc surface or a spherical surface. The sliding surface is integrally formed on the first end of the air guide plate 21. The arc surface or spherical surface design makes the contact area between the guide member 22 and the rotating section smaller, which is beneficial to reduce resistance. In some embodiments of this application, when the air guide plate 21 rotates counterclockwise and drives the rotating section 512 to rotate to avoid the rotation of the air guide plate, the guide member 22 is correspondingly disposed at the second end 21b of the air guide plate 21.

[0095] Please refer to some embodiments of this application. Figure 11 and Figure 12 The housing also includes a limiting member, which is disposed on the upper edge of the air outlet and extends into the air outlet; when the rotating section is in the initial state, the free end overlaps the side of the limiting member away from the air outlet.

[0096] It is understood that this embodiment provides a limiting member 30 inside the housing 10. The cooperation between the limiting member and the rotating plate helps to improve the sealing performance of the indoor unit of the air conditioner. At the same time, the limiting member 30 prevents the free end of the rotating section from rotating into the air outlet. During the process of the air guide plate 21 rotating from the first position to the third position, it will not rotate with the rotation of the air guide plate 21, thus avoiding blocking the air outlet 10a and affecting the airflow direction.

[0097] It is understandable that the fixing connection between the limiting component 30 and the housing 10 can be, but is not limited to, welding, screw fixing, bonding, integral molding, etc.

[0098] For example, the limiting member 30 can be integrally formed with the housing 10. The limiting member 30 is formed by extending horizontally into the housing 10 from the side of the housing 10 located above the air outlet 10a.

[0099] Please continue reading. Figure 12 In one embodiment, the free end 5121 may be inclined upward in a direction away from the air guide plate 21 to form an abutment portion 5121a. Exemplarily, the abutment portion 5121a has a plate-like structure. When the air guide plate 21 is in the first position or the second position, the rotating section 512 abuts against the limiting member 30 through the abutment portion 5121a. At this time, the abutment portion 5121a is parallel to the limiting member 30.

[0100] Please continue reading. Figure 7 In one embodiment, the width of the contact surface between the limiting member 30 and the abutting part 5121a is L3, where L3 ≥ 2mm. This makes the contact between the limiting member 30 and the rotating section surface when limiting the rotating section, resulting in better stability and better sealing of the air outlet duct.

[0101] Furthermore, a clearance opening is provided on the side of the free end 5121a near the bottom wall. Specifically, the clearance opening is located on the side of the abutment portion 5121a facing the air outlet duct 50, and the cross-section of the clearance opening is approximately L-shaped. When the rotating section 512 is in the initial state and the air guide plate 21 is in the first position, the end of the limiting member 30 away from the outer shell 10 is located inside the clearance opening, and the first end 5121a is located near the clearance opening. For example, the first end 5121a is close to the wall surface opposite the clearance opening and the limiting member 30. This embodiment is beneficial to improving the sealing performance of the air outlet 10a.

[0102] Please see Figure 11 and Figure 12 In one embodiment, a damping element 40 may be provided inside the housing. One end of the damping element 40 is connected to the inside of the housing, and the other end of the damping element 40 is connected to the side of the rotating section away from the guide plate. The damping element 40 is used to provide damping force when the rotating section rotates so that the rotating section will not produce abnormal noise or jamming during the rotation process.

[0103] It is understood that the damping element 40 can be directly connected to the inner wall of the housing, or it can be connected to the housing 10 through other connection structures, or it can be installed on the mounting part 11. This application embodiment does not limit this.

[0104] For example, one end of the damping element 40 can be connected to the mounting element 11.

[0105] It is understandable that the damping element 40 can be an elastic element with elasticity and deformation recovery capability, including but not limited to springs, torsion springs, etc.

[0106] Please see Figure 12 For example, the damping element 40 can be a spring. When the air guide plate 21 is in the first position or the second position, the damping element 40 is in a natural or compressed state.

[0107] This application also provides an air conditioner, which includes an outdoor unit and a wall-mounted indoor unit 1. The outdoor unit and the wall-mounted indoor unit 1 are connected by a refrigerant pipe. The specific structure of the wall-mounted indoor unit 1 is as described in the above embodiments.
