Abstract

This invention provides a swing assembly and an air conditioner, belonging to the field of air conditioning technology. The swing assembly includes an air guide plate, comprising an outer air guide plate and an inner air guide plate. The outer and inner air guide plates extend along the same length direction and at least partially overlap in length. The outer and inner air guide plates are configured to move relative to each other in the length direction to change the total effective length of the air guide plates, or they can rotate synchronously around an axis parallel to the length direction to adjust the air guiding direction. The air outlet assembly of this invention can change the air volume of the air conditioner outlet by changing the total effective length of the air guide plates. When the outer and inner air guide plates rotate synchronously, the air outlet direction of the air conditioner outlet can be changed simultaneously with the change in air volume.

Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more particularly to a swing assembly and an air conditioner. Background Technology

[0002] Air conditioners typically have deflector blades to achieve left and right airflow, improving the airflow effect and enhancing overall comfort.

[0003] Currently, there are many types of air sweeping blades, mainly involving changes in blade shape and position. However, they all suffer from low assembly efficiency, multiple motors, and high costs. This is especially true for cabinet air conditioners with dual or multiple air outlets, where there are even more parts related to the air sweeping blades.

[0004] For models with multiple air vents, the presence of air guides can affect the air delivery effect to some extent. Reducing the number of air guides will affect the air sweeping and delivery effect, as well as the sealing and insect prevention effect.

[0005] If each area's air guide plate is controlled individually, the number of parts will be large, leading to complex assembly. Summary of the Invention

[0006] To overcome the problems existing in related technologies, the present invention proposes a wind-sweeping assembly and an air conditioner.

[0007] The first aspect of this invention provides a sweeping assembly, comprising:

[0008] The air guide plate includes an outer air guide plate and an inner air guide plate. The outer air guide plate and the inner air guide plate extend along the same length direction and at least partially overlap in length. The outer air guide plate and the inner air guide plate are configured to be able to move relative to each other in the length direction to change the total effective length of the air guide plate, or to rotate synchronously around an axis parallel to the length direction to adjust the air guiding direction.

[0009] In the above technical solution, the air-sweeping assembly is suitable for air outlet equipment with multiple air outlets arranged along a certain direction, characterized in that the air-sweeping assembly includes:

[0010] The air guide plate can be driven to rotate in a first rotation direction or a second rotation direction. In the first rotation direction, there is a first limiting position that restricts the air guide plate from continuing to rotate in the first rotation direction, and in the second rotation direction, there is a second limiting position that restricts the air guide plate from continuing to rotate in the second rotation direction.

[0011] The air guide plate includes an outer air guide plate and an inner air guide plate that are nested together, and the inner air guide plate can move relative to the outer air guide plate in a first direction or a second direction.

[0012] The threaded rod is threadedly engaged with the inner air guide plate. When the threaded rod rotates, the inner air guide plate has at least the following motion states:

[0013] In the relative motion state, when the air guide plate is in the first limit position, the inner air guide plate can move relative to the threaded rod in the first rotation direction, so that the inner air guide plate moves relative to the outer air guide plate in the first direction. When the air guide plate is in the second limit position, the inner air guide plate can move relative to the outer threaded rod in the second direction, so that the inner air guide plate moves relative to the outer air guide plate in the second direction.

[0014] When the air guide plate is in the rotation state, and it is between the first limit position and the second limit position, driving the threaded rod to rotate in the first rotation direction or the second rotation direction can drive the inner air guide plate and the outer air guide plate to rotate synchronously in the first rotation direction or in the second rotation direction.

[0015] In the above technical solution, the air sweeping assembly also includes a mounting frame, and the air guide plate is rotatably mounted on the mounting frame. The mounting frame is provided with a first limit position and a second limit position. When the air guide plate is driven to rotate, it can be limited in its rotation direction by the first limit position and the second limit position.

[0016] In the above technical solution, the mounting frame is provided with a first limiting block, the first limiting block has a first limiting surface in the first rotation direction of the air guide plate, and a first limiting position is formed on the first limiting surface; the first limiting block has a second limiting surface in the second rotation direction of the air guide plate, and a second limiting position is formed on the second limiting surface; or

[0017] The mounting frame is provided with a first limiting block and a second limiting block. The first limiting block has a first limiting surface in the first rotation direction of the air guide plate, and a first limiting position is formed on the first limiting surface. The second limiting block has a second limiting surface in the second rotation direction of the air guide plate, and a second limiting position is formed on the second limiting surface.

[0018] In the above technical solution, when the first limiting position and the second limiting position are respectively formed on the first limiting block and the second limiting block, the first limiting block and the second limiting block are spaced apart by a distance in the rotation direction of the air guide plate.

[0019] The distance between the first and second limit blocks in the direction of rotation of the air guide plate can be adjusted.

[0020] In the above technical solution, there are multiple air guide plates, and the multiple air guide plates can be installed on the mounting frame in a coordinated manner;

[0021] The first and second limit positions are set on the rotation path of at least one air guide plate.

[0022] In the above technical solution, the mounting frame is provided with a connecting rod, and multiple mounting positions are evenly distributed on the connecting rod. An external air guide plate is installed in each mounting position to limit the movement of the external air guide plate along the first direction or the second direction.

[0023] In the above technical solution, when the air guide plate is in the first limit position or the second limit position, the two adjacent air guide plates partially overlap in the air outlet direction.

[0024] When the air guide plate is between the first limit position and the second limit position, the two adjacent air guide plates do not overlap in the air outlet direction.

[0025] In the above technical solution, the inner air guide plate is also provided with a limiting member whose position is fixed relative to the inner air guide plate. One end of the limiting member elastically presses against the outer air guide plate or the inner air guide plate, and the other end elastically presses against the two adjacent threaded grooves on the threaded rod.

[0026] When the air guide plate rotates between the first limit position and the second limit position, the limiting member is used to restrict the movement of the inner air guide plate relative to the threaded rod in the first direction or the second direction.

[0027] In the above technical solution, the limiting component includes a spring and a limiting rod. One end of the limiting component is pressed against the outer or inner air guide plate by the spring, and the other end is pressed against two adjacent threaded grooves on the threaded rod by the limiting rod.

[0028] When the threaded rod drives the inner guide plate to rotate between the first and second limit positions, the resistance experienced by the inner guide plate in the direction of rotation is less than the resistance between the limit rod and the threaded rod.

[0029] In the above technical solution, the outer air guide plate is a hollow plate-shaped body with an internal cavity and an opening communicating with the cavity is provided at least one end of the outer air guide plate in the length direction. The inner air guide plate has a first end and a second end in the length direction. The first end of the inner air guide plate is installed in the cavity of the outer air guide plate through the opening. The threaded rod is provided in the cavity and is threadedly driven to cooperate with the inner air guide plate.

[0030] The threaded rod has a groove on its side wall, and the groove is located between two adjacent threaded grooves on the threaded rod.

[0031] The groove is set on the side of the threaded rod near the opening of the outer air guide plate, and the limiting member is set on the side of the inner air guide plate near the first end;

[0032] When the inner air guide plate is driven by the threaded rod to move outward from the cavity of the outer air guide plate, the end of the limiting member pressing against the threaded rod can be embedded in the groove on the threaded rod.

[0033] In the above technical solution, the outer air guide plate is provided with multiple first micro-holes and / or the inner air guide plate is provided with multiple second micro-holes;

[0034] When the inner air guide plate is placed inside the outer air guide plate, the first micro-hole is blocked by the inner air guide plate and / or the second micro-hole is blocked by the outer air guide plate.

[0035] In the above technical solution, the inner air guide plate is provided with a humidification chamber and a heating chamber.

[0036] A second aspect of the present invention provides an air conditioner employing the aforementioned air-sweeping assembly.

[0037] In the above technical solution, the air conditioner includes a cabinet air conditioner, the air conditioner includes a decorative panel, two air outlets are arranged in the height direction of the decorative panel, and the air guide plate is arranged along the height direction of the decorative panel.

[0038] The air conditioner also includes an air outlet assembly, an evaporator assembly, and a rear casing, with the decorative panel, air outlet assembly, evaporator assembly, and rear casing arranged sequentially from one side to the other in the width direction of the air conditioner;

[0039] The air sweeping component is located between the decorative panel and the air outlet component.

[0040] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0041] 1. In the embodiments of the present invention, the outer air guide plate and the inner air guide plate are arranged to extend along the same length direction and at least part of their lengths are set to overlap. When the outer air guide plate and the inner air guide plate move relative to each other, the total effective length of the air guide plate can be changed. When the air guide plate is installed on the air conditioner, the air volume of the air outlet of the air conditioner can be changed by changing the total effective length of the air guide plate (that is, blocking part or all of the air outlet). When the outer air guide plate and the inner air guide plate rotate synchronously, the air outlet direction of the air conditioner can also be changed while changing the air volume of the air outlet.

Detailed Implementation

[0055] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0056] Currently, air conditioners with multiple air vents on the market often have air guide vanes that can affect airflow performance to some extent. Reducing the number of air guide vanes, however, can negatively impact the airflow distribution and sealing / insect-proofing effects. In this embodiment of the invention, the outer and inner air guide vanes are designed to extend along the same length direction and overlap at least partially. When the outer and inner air guide vanes move relative to each other, their total effective length can be changed. When the air guide vanes are installed on the air conditioner, the airflow volume at the air outlet can be altered by changing the total effective length of the air guide vanes (i.e., partially or completely blocking the air outlet). When the outer and inner air guide vanes rotate synchronously, the airflow direction at the air outlet can also be changed simultaneously with the airflow volume.

[0057] The following is in conjunction with the appendix Figure 1-11 The technical solution of this embodiment is described in detail. Unless otherwise specified, the following implementation methods and embodiments can be combined with each other.

[0058] Example

[0059] On the one hand, such as Figure 1 and Figure 2 As shown, this embodiment proposes a sweeping assembly, including:

[0060] The air guide plate includes an outer air guide plate 11 and an inner air guide plate 12. The outer air guide plate 11 and the inner air guide plate 12 extend along the same length direction and at least partially overlap in length. The outer air guide plate 11 and the inner air guide plate 12 are configured to be able to move relative to each other in the length direction to change the total effective length of the air guide plate, or to rotate synchronously around an axis parallel to the length direction to adjust the air guiding direction.

[0061] In this embodiment of the invention, the outer air guide plate 11 and the inner air guide plate 12 are arranged to extend along the same length direction and at least part of their lengths are overlapped. When the outer air guide plate 11 and the inner air guide plate 12 move relative to each other, the total effective length of the air guide plate can be changed. When the air guide plate is installed on the air conditioner, the air volume of the air outlet of the air conditioner can be changed by changing the total effective length of the air guide plate (that is, partially or completely blocking the air outlet). When the outer air guide plate 11 and the inner air guide plate 12 rotate synchronously, the air outlet direction of the air conditioner can also be changed while changing the air volume of the air outlet.

[0062] Specifically, when the outer air guide plate 11 and the inner air guide plate 12 move relative to each other, the outer air guide plate 11 can be driven to move relative to the inner air guide plate 12, or the inner air guide plate 12 can be driven to move relative to the outer air guide plate 11. More specifically, the outer air guide plate 11 and the inner air guide plate 12 can be driven to move relative to each other by driving elements such as cylinders or motors.

[0063] In any of the above embodiments, such as Figure 1and Figure 2 As shown, the air-sweeping assembly is suitable for air outlet equipment with multiple air outlets arranged in a certain direction, wherein:

[0064] The air guide plate 1 can be driven to rotate along a first rotation direction or a second rotation direction. The first rotation direction has a first limiting position that restricts the air guide plate 1 from continuing to rotate along the first rotation direction, and the second rotation direction has a second limiting position that restricts the air guide plate 1 from continuing to rotate along the second rotation direction. The air guide plate 1 includes an outer air guide plate 11 and an inner air guide plate 12 that are nested together, and the inner air guide plate 12 can move relative to the outer air guide plate 11 along the first direction or the second direction. Preferably, the outer air guide plate 11 and the inner air guide plate 12 are blade-shaped plates.

[0065] The threaded rod 2 is threadedly engaged with the inner air guide plate 12. When the threaded rod 2 is driven to rotate by the motor, the inner air guide plate 12 has at least the following motion states:

[0066] In the relative motion state, when the air guide plate 1 is in the first limit position, the inner air guide plate 12 can move relative to the threaded rod 2 in the first rotation direction, so that the inner air guide plate 12 moves relative to the outer air guide plate 11 in the first direction. When the air guide plate 1 is in the second limit position, the inner air guide plate 12 can move relative to the threaded rod 2 in the second rotation direction, so that the inner air guide plate 12 moves relative to the outer air guide plate 11 in the second direction.

[0067] When the air guide plate 1 is in the rotation state and is between the first limit position and the second limit position, driving the threaded rod 2 to rotate in the first rotation direction or the second rotation direction can drive the inner air guide plate 12 and the outer air guide plate 11 to rotate synchronously in the first rotation direction or synchronously in the second rotation direction.

[0068] In this embodiment of the invention, the air guide plate 1 is configured as a sleeve, and the air guide plate 1 and the threaded rod 2 are connected by a threaded transmission. Limiting positions (first limit position and second limit position) are set in the circumferential direction of the air guide plate's rotation. When the threaded rod 2 rotates, it not only drives the inner air guide plate 12 to rise and fall relative to the outer air guide plate 11, but also drives the inner air guide plate 12 and the outer air guide plate 11 to rotate synchronously. Thus, by using only one driving component (i.e., the threaded rod 2), the presence or absence of the air guide plate 1 at at least one air outlet can be controlled, and the rotation of the air guide plate 1 can also be controlled, thereby ensuring the effect of sweeping and air delivery. Specifically;

[0069] When the air guide plate 1 is in the first limit position, and the threaded rod 2 is driven by the motor to rotate in the first rotation direction, the outer air guide plate 11 cannot continue to rotate in the first rotation direction because it is restricted by the first limit position. Therefore, the inner air guide plate 12 will undergo threaded transmission with the threaded rod 2, and the inner air guide plate 12 will move relative to the outer air guide plate 11 in the first direction. When the inner air guide plate 12 moves relative to the outer air guide plate 11 in the first direction, the inner air guide plate 12 can block part or all of the air outlet (or block one or more air outlets, depending on the length of the air guide plate).

[0070] When the air guide plate 1 is in the second limit position, and the threaded rod 2 is driven by the motor to rotate in the second rotation direction, the outer air guide plate 11 is restricted by the first limit position and cannot continue to rotate in the second rotation direction. Therefore, the inner air guide plate 12 will undergo threaded transmission with the threaded rod 2, and the inner air guide plate 12 will move relative to the outer air guide plate 11 in the second direction. When the inner air guide plate 12 moves relative to the outer air guide plate 11 in the second direction, the inner air guide plate 12 can open part or all of the air outlets (or open one or more air outlets, depending on the length of the air guide plate).

[0071] When the air guide plate 1 is between the first and second limit positions, the motor drives the threaded rod 2 to rotate in the first or second rotation direction. Since the outer air guide plate 11 is not restricted in the rotation direction, the rotation of the threaded rod 2 will drive the outer air guide plate 11 to rotate synchronously along the first or second rotation direction through the inner air guide plate 12. This achieves the air sweeping effect of the air guide plate.

[0072] It is worth noting that the first direction, second direction, first rotation direction, and second rotation direction described in this embodiment are relative directions defined for ease of understanding the working principle of the present invention. In actual products, when the air guide plate 1 is in the first limiting position, driving the threaded rod 2 to rotate in the first rotation direction, the inner air guide plate 12 can also move relative to the threaded rod 2 in the second direction so that the inner air guide plate 12 moves relative to the outer air guide plate 11 in the second direction. When the air guide plate 1 is in the second limiting position, driving the threaded rod 2 to rotate in the second rotation direction, the inner air guide plate 12 can also move relative to the threaded rod 2 in the first direction so that the inner air guide plate 12 moves relative to the outer air guide plate 11 in the first direction. Specifically, in Figure 1 In the example, the first direction is the direction in which the inner air guide plate 12 moves upward, the second direction is the direction in which the inner air guide plate 12 moves downward, the first rotation direction is the clockwise rotation direction of the inner air guide plate, and the second rotation direction is the counterclockwise rotation direction of the inner air guide plate 12.

[0073] In any of the above embodiments, such as Figure 3As shown, the air sweeping assembly also includes a mounting frame 10, on which the air guide plate is rotatably mounted. The mounting frame 10 is provided with a first limiting position and a second limiting position. When the air guide plate is driven to rotate, it can be limited in its rotation direction by the first limiting position and the second limiting position.

[0074] In any of the above embodiments, such as Figure 3 As shown, only one first limiting block 3 can be set on the mounting frame 10. The first limiting block 3 has a first limiting surface 31 in the first rotation direction of the air guide plate 1, and a first limiting position is formed on the first limiting surface 31. The first limiting block 3 has a second limiting surface 32 in the second rotation direction of the air guide plate 1, and a second limiting position is formed on the second limiting surface 32.

[0075] In any of the above embodiments, the mounting frame 10 may also be provided with a first limiting block and a second limiting block at the same time. The first limiting block has a first limiting surface in the first rotation direction of the air guide plate 1, and a first limiting position is formed on the first limiting surface. The second limiting block has a second limiting surface in the second rotation direction of the air guide plate 1, and a second limiting position is formed on the second limiting surface.

[0076] In this embodiment of the invention, one or two limiting blocks are set on the rotation path of the air guide plate 1. The limiting blocks can restrict the rotation direction of the outer air guide plate 11, thereby achieving the relative motion effect of the inner air guide plate 12 relative to the outer air guide plate 11. This eliminates the need for two driving components (one to drive the air guide plate to rotate and the other to drive the air guide plate to rise and fall). In other words, the different movement modes of the two air guide plates (outer air guide plate 11 and inner air guide plate 12) can be controlled by one motor, reducing the number of parts and improving efficiency.

[0077] It is worth noting that when the first limit position and the second limit position are respectively formed on the first limit block and the second limit block, the first limit block and the second limit block are spaced apart in the rotation direction of the air guide plate.

[0078] The distance between the first and second limit blocks in the direction of rotation of the air guide plate can be adjusted.

[0079] The distance between the first and second limit blocks in the direction of rotation of the air guide plate can be adjusted to control the maximum airflow through the air guide plate. This prevents excessive airflow from affecting the user experience when the air conditioner is operating in left-right swing mode.

[0080] In any of the above embodiments, multiple air guide plates 1 are provided, and the multiple air guide plates 1 can be installed on the mounting frame 10 in a coordinated manner.

[0081] The aforementioned first and second limiting positions are formed on the rotation path of at least one air guide plate 1.

[0082] In this embodiment of the invention, the synchronous sweeping effect of multiple air guide plates can be achieved by setting a limiting block on the rotation path of at least one of the multiple air guide plates 1, without having to set multiple limiting blocks to restrict the rotation direction of each air guide plate 1. (It is worth noting that the linkage between the multiple air guide plates 1 can be achieved by the abutment linkage between the plates or by the transmission method of belt drive. The linkage method between the multiple air guide plates 1 will not be described in detail in this embodiment.)

[0083] In any of the above embodiments, such as Figure 3 As shown, the mounting frame 10 is provided with a connecting rod 33, and multiple mounting positions are evenly distributed on the connecting rod 33. An external air guide plate 11 is installed in each mounting position to limit the movement of the external air guide plate 11 along the first direction or the second direction.

[0084] In this embodiment of the invention, by setting the outer air guide plate 11 on the connecting rod 33 to restrict the movement of the outer air guide plate 11 along the first direction and the second direction, the outer air guide plate 11 is used as a reference, thereby preventing the inner air guide plate 12 from moving relative to the outer air guide plate 11 along the first direction or the second direction, thus allowing the inner air guide plate 12 to move relative to the outer air guide plate 11.

[0085] It is worth noting that, in this embodiment, the connecting rod 33 can be hinged to the mounting frame 10, and the outer air guide plate 11 can be fixed to the mounting frame 10. Alternatively, the connecting rod 33 can be fixed to the mounting frame 10, and the outer air guide plate 11 can be hinged to the connecting rod 33. This embodiment does not limit the specific installation method of the connecting rod 33.

[0086] In any of the above embodiments, such as Figure 6 As shown, the mounting frame is provided with multiple air outlets 4. Preferably, the number of air outlets is set to two, wherein;

[0087] When the air guide plate 1 is in the first limit position or the second limit position, the two adjacent air guide plates 1 partially overlap in the air outlet direction of the air outlet 4.

[0088] When the air guide plate 1 is between the first limit position and the second limit position, the two adjacent air guide plates 1 do not overlap in the air outlet direction of the air outlet 4.

[0089] In this embodiment of the invention, when the inner air guide plate 12 is raised or lowered relative to the outer air guide plate 11, the air guide plate as a whole blocks the air outlet (that is, the outer air guide plate 11 and the inner air guide plate 12 block the air outlet, that is, the air outlet is in a closed state, thereby avoiding the air outlet from still emitting air when the air guide plate is raised or lowered, thereby avoiding chaotic airflow and generating large noise, and at the same time avoiding the impact of chaotic airflow on the user experience).

[0090] In any of the above embodiments, such as Figure 2 , Figure 4 and Figure 5 As shown, the inner air guide plate 12 is also provided with a limiting member 5 whose position is fixed relative to the inner air guide plate 12. One end of the limiting member 5 elastically presses against the outer air guide plate 11 or the inner air guide plate 12, and the other end elastically presses against the two adjacent threaded grooves on the threaded rod 2.

[0091] When the air guide plate 1 rotates between the first limit position and the second limit position, the limiting member 5 is used to restrict the inner air guide plate 12 from moving relative to the threaded rod 2 in the first direction or the second direction.

[0092] This avoids the inner air guide plate 12 from rising and falling relative to the outer air guide plate 11 when the inner air guide plate 12 and the outer air guide plate 11 rotate synchronously (i.e., during air sweeping). This ensures that the rotation of the inner air guide plate 12 and the outer air guide plate 11 fixes the position of the outer air guide plate 11 in the height direction, improving the air sweeping effect of the air guide plates.

[0093] In any of the above embodiments, such as Figure 4 As shown, the limiting member 5 includes a spring 51 and a limiting rod 52. One end of the limiting member 5 is pressed against the outer air guide plate 11 or the inner air guide plate 12 by the spring 51, and the other end is pressed against two adjacent threaded grooves on the threaded rod 2 by the limiting rod 52. Preferably, the spring 51 is sleeved on the outside of the limiting rod 52, the spring 51 is pressed against the inner wall of the outer air guide plate 11, and the limiting rod 52 is elastically pressed against the threaded rod 2 by the spring force.

[0094] When the threaded rod 2 drives the inner guide plate 12 to rotate between the first and second limit positions, the resistance experienced by the inner guide plate 12 in the rotation direction is less than the resistance between the limit rod 52 and the threaded rod 2. This avoids the situation where the inner guide plate 12 rises and falls relative to the outer guide plate 11 while the outer guide plate 11 and the inner guide plate 12 are rotating between the first and second limit positions. This ensures that the guide plates do not interfere with each other when moving in either state (i.e., when the outer guide plate 11 and the inner guide plate 12 rotate synchronously, the inner guide plate 12 will not rise and fall relative to the outer guide plate 11, and when the inner guide plate 12 rises and falls relative to the outer guide plate 11, neither the outer guide plate 11 nor the inner guide plate 12 will rotate). This allows for more precise control of the guide plate's movement.

[0095] In any of the above embodiments, such as Figure 1 , Figure 2 and Figure 5As shown, the outer air guide plate 11 is a hollow plate-shaped body with an internal cavity, and at least one end of the outer air guide plate 11 in the length direction has an opening that communicates with the cavity. The inner air guide plate 12 has a first end 121 and a second end 122 in the length direction. The first end of the inner air guide plate 12 is installed in the cavity of the outer air guide plate 11 through the opening. The threaded rod 2 is provided in the cavity and is threadedly driven to cooperate with the inner air guide plate 12.

[0096] The threaded rod 2 has a groove 21 on its side wall, and the groove 21 is located between two adjacent threaded grooves on the threaded rod 2. The limiting member 5 is located on the inner air guide plate 12 on the side near the first end 121.

[0097] When the inner air guide plate 12 is driven by the threaded rod 2 to move outward from the cavity of the outer air guide plate 11, the end of the limiting member 5 that presses against the threaded rod 2 can be embedded in the groove 21 on the threaded rod 2.

[0098] Specifically, the groove 21 is provided on the side of the threaded rod 2 near the opening of the outer air guide plate 11. By providing the groove 21 on the side of the threaded rod 2, the inner air guide plate 12 can be prevented from detaching from the outer air guide plate 11. At the same time, since the groove 21 is provided on the side of the threaded rod 2 near the opening of the outer air guide plate 11, the extension of the inner air guide plate 12 relative to the outer air guide plate 11 can be maximized.

[0099] In some embodiments not shown, the outer air guide plate 11 is provided with a plurality of first micro-holes and / or the inner air guide plate 12 is provided with a plurality of second micro-holes;

[0100] When the inner air guide plate 12 is placed in the outer air guide plate 11, the first micro-hole is blocked by the inner air guide plate 12 and / or the second micro-hole is blocked by the outer air guide plate 11.

[0101] For example, multiple first micro-holes are provided on the outer air guide plate 11, and multiple second micro-holes are provided on the inner air guide plate 12. When the outer air guide plate 11 and the inner air guide plate 12 overlap, the multiple first micro-holes and the multiple second micro-holes are mutually shielded. However, after unfolding (i.e., the inner air guide plate 12 relative to the outer air guide plate 11 along the axis of this embodiment), the micro-holes and the second micro-holes are mutually shielded. Figure 2 When the first direction of movement is shown, it becomes a micro-hole air outlet.

[0102] In some embodiments not shown, a humidification chamber and a heating chamber may also be provided on the inner air guide plate 12. For example, by using a heating rod on the inner air guide plate 12 and combining it with a humidification function, a better air supply and air guiding effect can be achieved.

[0103] On the other hand, such as Figures 7-10 As shown in the figure, an air conditioner is also provided in this embodiment of the invention, which uses the aforementioned air-sweeping component.

[0104] In any of the above embodiments, the air conditioner includes a cabinet air conditioner, the air conditioner includes a decorative panel 6, and two air outlets are arranged in the height direction of the decorative panel 6, wherein each air outlet is provided with a fan, and the air guide plate is arranged along the height direction of the decorative panel 6.

[0105] Specifically, the air conditioner also includes an air outlet assembly 7, an evaporator assembly 8, and a rear casing 9, wherein the decorative panel 6, the air outlet assembly 7, the evaporator assembly 8, and the rear casing 9 are arranged sequentially from one side to the other in the width direction of the air conditioner;

[0106] The air-sweeping component is located between the decorative panel 6 and the air-outlet component 7.

[0107] The following is combined Figures 8-10 The working principle of the air conditioner in the embodiments of the present invention will be explained in detail below:

[0108] Figure 8 This is a schematic diagram of the first air outlet state of an air conditioner. In the diagram, there is no air guide plate at the upper air outlet, ensuring unobstructed airflow and high efficiency. The lower air outlet allows for air sweeping. The overall effect is as follows:

[0109] ① The orientation of the lower air guide plate (i.e., the outer air guide plate) has been changed to prevent the lower air outlet from blowing air into people;

[0110] ②The air supply distance from the top is longer, so turning on the top fan is relatively energy-efficient.

[0111] Figure 9 This is a schematic diagram of the second air outlet state of the air conditioner, in which the air guide plate is... Figure 8 The state is adjusted so that the inner air guide plate 12 partially blocks the upper air outlet of the air conditioner, which is equivalent to controlling the sweeping direction of the upper air outlet.

[0112] Figure 10 This is a diagram illustrating the third airflow state of an air conditioner, where the air guide vane is... Figure 9 The air conditioner is in a state where the inner air guide plate 12 is fully extended from the outer air guide plate 11. The limiting rod is engaged in the groove 21 of the threaded rod 2 (to prevent the inner air guide plate 12 from rotating out). The entire unit can now perform left and right airflow, and this is also the off state of the air conditioner. Although the upper inner air guide plate 12 is slightly smaller than the lower outer air guide plate 11, the air guide plate itself has a certain angle (which is visible). Figure 3 The structure of the central air guide plate is such that there are no gaps when viewed from the front, and the decorative panel 6 has a vertical grille effect, which can also cover up the overlapping gaps to a certain extent and beautify the appearance.

[0113] like Figure 11 As shown, the adjustment state of the air guide plate refers to tilting the entire air guide plate 1 to one end to its maximum position (as shown). Figure 11(When the motor is turned to the maximum position to the right), due to the restriction of the first limit block 3 on the mounting frame 10, when the air guide plate 1 is rotated to this position, the outer air guide plate 11 no longer rotates. When the motor continues to rotate, the threaded rod 2 starts to rotate, that is, the inner air guide plate 12 begins to adjust its height. When it is adjusted to the appropriate height, the motor rotates back, and the adjustment state is released. Since the pressure of the spring 51 is greater than the normal rotational force, the height of the air guide plate is basically determined at this time, and left and right sweeping can be performed. When it is necessary to reset, a similar method is used. When the motor is turned to the maximum position on the other side, the air guide plate 1 will start to return to its original position due to the action of the first limit block 3. The corresponding positions and relationships of the motors are as follows: Figure 11 As shown. Since the air guide vane is controlled by a stepper motor, its height and position can be controlled by time.

[0114] In a dual-fan system, to achieve rapid room cooling or improve overall comfort, a combination of upper and lower fans can be used, with different air delivery distances controlled as follows:

[0115]

[0116] The air conditioner of this embodiment of the invention has significant advantages due to the use of the above-mentioned air-sweeping component, which has low cost, high efficiency, and the ability to achieve multiple air output effects.

[0117] It is worth noting that in the above embodiments, the external air guide plate is located on the lower side. Of course, in some embodiments not shown, the external air guide plate can also be located on the upper side, that is, the air outlet on the lower side can be controlled to open and close.
