Description

Technical Field

[0001] This invention relates to the field of heat exchange equipment technology, and more specifically, to a duct assembly and a heat exchange device. Background Technology

[0002] Air conditioners typically consist of an indoor unit and an outdoor unit. Air is delivered to the indoor area by installing an air deflector at the air outlet of the outdoor unit. However, the air deflector of existing indoor units has a small air delivery angle, and the existing air deflector control method is relatively simple, which makes it impossible to achieve wide-angle air delivery of the air conditioner. Summary of the Invention

[0003] The main objective of this invention is to provide an air duct assembly and heat exchange device to solve the problem that the control method of the air guide plate in the existing air conditioner is singular and cannot achieve wide-angle air delivery.

[0004] To achieve the above objectives, according to one aspect of the present invention, an air duct assembly is provided, including an air outlet frame and an air guide mechanism. The air outlet frame has an air outlet divided into multiple air outlet areas. The air guide mechanism has multiple air guide plates, each air guide plate being rotatably disposed at the air outlet. At least one air guide plate is disposed in each air outlet area. The timing of the operation of the air guide plates in different air outlet areas is not exactly the same. The air guide plates of the two air outlet areas located on both sides of the air outlet have opposite rotation angles, so that the air guide plates of the two air outlet areas on both sides open into a wide-mouth state to achieve wide-angle air delivery.

[0005] Furthermore, the first angle of the air guide plates in the two air outlet areas located on both sides of the air outlet is A, where 0°≤A≤100°.

[0006] Furthermore, in addition to the two air outlet areas on both sides of the air outlet, the guide vanes of the remaining air outlet areas in the multiple air outlet areas can be rotated independently to perform continuous air sweeping; and / or, in addition to the two air outlet areas on both sides of the air outlet, the guide vanes of the remaining air outlet areas in the multiple air outlet areas can be rotated independently to a preset angle to perform directional air guidance.

[0007] Furthermore, in addition to the two air outlet areas on both sides of the air outlet, the second angle of the air guide plate in the remaining air outlet areas of the multiple air outlet areas is B, where 0°≤B≤120°.

[0008] Furthermore, the air guiding mechanism also includes a first transmission unit, a second transmission unit, and a drive unit. The first transmission unit is driven to the air guide plates of the two air outlet areas located on both sides of the air outlet, so as to drive the air guide plates of the two air outlet areas located on both sides of the air outlet to rotate by a first angle A. The second transmission unit is driven to the air guide plates of the remaining air outlet areas in the plurality of air outlet areas other than the two air outlet areas on both sides of the air outlet, so as to drive the air guide plates of the remaining air outlet areas in the plurality of air outlet areas other than the two air outlet areas on both sides of the air outlet to rotate by a second angle B. The drive unit is sequentially driven to the first transmission unit and the second transmission unit, so that when the air guide plates of the two air outlet areas located on both sides of the air outlet are opened to a flared state, the air guide plates of the remaining air outlet areas in the plurality of air outlet areas other than the two air outlet areas on both sides of the air outlet begin to rotate.

[0009] Furthermore, the first transmission part and the second transmission part are disposed at a distance from each other, and the drive part is disposed between the first transmission part and the second transmission part.

[0010] Furthermore, the drive unit includes an intermittent drive structure, which is rotatably disposed and has a drive region and an intermittent region. When the drive region faces the first transmission unit and the intermittent region faces the second transmission unit, the intermittent drive structure is driven connected to the first transmission unit through the drive region, and the second transmission unit is in an intermittent state. When the drive region faces the second transmission unit and the intermittent region faces the first transmission unit, the intermittent drive structure is driven connected to the second transmission unit through the drive region, and the first transmission unit is in an intermittent state.

[0011] Furthermore, the driving region includes a first sub-driving region and a second sub-driving region, and the intermittent region includes a first sub-intermittent region and a second sub-intermittent region. The intermittent driving structure includes a transmission shaft, a first sub-driving structure, a second sub-driving structure, and a drive motor. The first sub-driving structure and the second sub-driving structure are connected by the transmission shaft. The first sub-driving structure has a first sub-driving region and a first sub-intermittent region to intermittently drive the first transmission unit. The second sub-driving structure has a second sub-driving region and a second sub-intermittent region to intermittently drive the second transmission unit. The drive motor has a drive shaft, which is drivenly connected to the transmission shaft to drive the first sub-driving structure and the second sub-driving structure to rotate synchronously.

[0012] Furthermore, the first sub-drive region has a first tooth, the first transmission unit has a first gear structure for meshing with the first tooth, and the first sub-interval region is an arc-shaped surface; and / or, the second sub-drive region has a second tooth, the second transmission unit has a second gear structure for meshing with the second tooth, and the second sub-interval region is an arc-shaped surface.

[0013] Furthermore, the first sub-drive structure and the second sub-drive structure are coaxially arranged; and / or, the drive motor and the intermittent drive structure are coaxially arranged.

[0014] Furthermore, the position of the first sub-driving structure having the first sub-driving region is on the same side as the position of the second sub-driving structure having the second sub-driving region.

[0015] Furthermore, the first central angle of the first sub-driving region on the first sub-driving structure is C1, and the second central angle of the second sub-driving region on the second sub-driving structure is C2, wherein the first central angle C1 and the second central angle C2 satisfy: C1≤C2.

[0016] Furthermore, the first central angle C1 of the first sub-driving region on the first sub-driving structure is 100°; and / or, the second central angle C2 of the second sub-driving region on the second sub-driving structure is 120°.

[0017] Furthermore, the air guiding mechanism also includes a support structure, which is mounted on the air outlet frame; each air guide plate is rotatably connected to the support structure via its own pivot shaft; wherein, the pivot shafts on the air guide plates of the multiple air outlet areas, except for the two air outlet areas on both sides of the air outlet, pass through the support plate of the support structure and are connected to the second gear structure of the second transmission unit; the pivot shafts on the air guide plates of the two air outlet areas located on both sides of the air outlet pass through the support plate and are connected to the two transmission linkage mechanisms of the first transmission unit, and the first gear structure of the first transmission unit is driven and connected to the two transmission linkage mechanisms respectively.

[0018] Furthermore, the support structure includes a support plate and a mounting plate. The mounting plate is disposed on the support plate, and there is a clearance space between the mounting plate and the support plate. The first gear structure is disposed on the mounting plate and located in the clearance space. The end face of the first gear structure facing the support plate has two gear pivot shafts. The first transmission part also includes two transmission linkage mechanisms. One end of the two transmission linkage mechanisms is used to connect with the two gear pivot shafts respectively, and the other end of the two transmission linkage mechanisms is used to pivotally connect with the two air guide plates at the two side edges respectively.

[0019] Furthermore, the transmission linkage mechanism includes two pivotally connected sub-links, the length of which of the two sub-links is connected to the first gear structure and is greater than the length of which of the two sub-links is connected to the air guide plate at the edge.

[0020] According to another aspect of the present invention, a heat exchange device is provided, including a duct assembly, wherein the duct assembly is the duct assembly described above.

[0021] Applying the technical solution of this invention, the air guiding mechanism has multiple air guiding plates, each of which is rotatably set at the air outlet. The air guiding plates of the two air outlet areas on both sides of the air outlet have opposite rotation angles, so that the air guiding plates of the two air outlet areas on both sides open into a wide-mouth state, increasing the air delivery angle and realizing wide-angle air delivery. Moreover, the timing of the action of at least one air guiding plate is not exactly the same as that of the air guiding plates on both sides, so that at least one air guiding plate can be controlled independently. By changing the rotation direction of the air guiding plate, at least one air guiding plate can be controlled independently, thereby changing the sweeping air direction. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] To address the problem that the control method of the air guide plate in existing air conditioners is singular and cannot achieve wide-angle air delivery, this invention provides an air duct assembly and a heat exchange device. The heat exchange device includes an air duct assembly, which is the air duct assembly described above and below.

[0042] like Figures 1 to 13 As shown, the air duct assembly includes an air outlet frame 10 and an air guide mechanism 20. The air outlet frame 10 has an air outlet 11, which is divided into multiple air outlet areas. The air guide mechanism 20 has multiple air guide plates 21, each of which is rotatably mounted at the air outlet 11. At least one air guide plate 21 is provided in each air outlet area. The timing of the operation of the air guide plates 21 in different air outlet areas is not exactly the same. The air guide plates 21 in the two air outlet areas located on both sides of the air outlet 11 have opposite rotation angles so that the air guide plates 21 in the two air outlet areas on both sides open into a wide-mouth state to achieve wide-angle air supply.

[0043] Applying the technical solution of the present invention, the air guiding mechanism 20 has multiple air guiding plates 21, each of which is rotatably arranged at the air outlet 11. The air guiding plates 21 of the two air outlet areas on both sides of the air outlet 11 have opposite rotation angles, so that the air guiding plates 21 of the two air outlet areas on both sides open into a wide-mouth state, increasing the air delivery angle and realizing wide-angle air delivery. Moreover, the timing of the action of at least one air guiding plate 21 is not exactly the same as that of the air guiding plates 21 on both sides, so that at least one air guiding plate 21 can be controlled independently. By changing the moving direction of the air guiding plate 21, the sweeping air direction can be changed.

[0044] like Figures 5 to 13 As shown, the first angle of the air guide plates 21 in the two air outlet areas on both sides of the air outlet 11 is A, where 0°≤A≤100°. In this way, by reasonably optimizing the first angle A of the air guide plates 21 in the two air outlet areas on both sides of the air outlet 11, it is ensured that the air guide plates 21 in the two air outlet areas on both sides of the air outlet 11 will not interfere with other components of the air guiding mechanism 20 during rotation, and it can also ensure that the air guide plates 21 in the two air outlet areas on both sides open into a flared state, thereby realizing wide-angle air supply.

[0045] It should be noted that in this application, the second angle of the guide plate 21 in the remaining air outlet areas (excluding the two air outlet areas on both sides of the air outlet 11) is B, where 0°≤B≤120°. By reasonably optimizing the second angle B of the guide plate 21 in the remaining air outlet areas (excluding the two air outlet areas on both sides of the air outlet 11), it is ensured that the guide plate 21 in the remaining air outlet areas (excluding the two air outlet areas on both sides of the air outlet 11) will not interfere with other components of the air guiding mechanism 20 during rotation. It also ensures that the guide plate 21 in the remaining air outlet areas (excluding the two air outlet areas on both sides of the air outlet 11) can achieve directional airflow or continuous sweeping between the maximum position and the closed position, improving the diversity of airflow methods and providing users with a better air delivery experience.

[0046] like Figures 2 to 13 As shown, the air guiding mechanism 20 also includes a first transmission part 22, a second transmission part 23, and a drive part 24. The first transmission part 22 is connected to the air guide plates 21 of the two air outlet areas on both sides of the air outlet 11 to drive the air guide plates 21 of the two air outlet areas on both sides of the air outlet 11 to rotate by a first angle A. The second transmission part 23 is connected to the air guide plates 21 of the remaining air outlet areas in the plurality of air outlet areas other than the two air outlet areas on both sides of the air outlet 11 to drive the air guide plates 21 of the remaining air outlet areas in the plurality of air outlet areas to rotate by a second angle B. The drive part 24 is sequentially connected to the first transmission part 22 and the second transmission part 23 to drive the air guide plates 21 of the remaining air outlet areas in the plurality of air outlet areas other than the two air outlet areas on both sides of the air outlet 11 to start rotating when the air guide plates 21 of the two air outlet areas on both sides of the air outlet 11 are opened in a flared state. In this way, the first transmission unit 22 drives the two air guide plates 21 on both sides of the air outlet 11 to rotate, and the second transmission unit 23 drives the air guide plate 21 in the middle to rotate, realizing the individual control of the air guide plate 21. When the drive unit 24 opens the air guide plates 21 on both sides of the air outlet 11 to the flared state, the air guide plate 21 in the middle starts to rotate, realizing that the air conditioner can perform multi-directional air sweeping or directional air guiding when the air conditioner delivers air in a wide angle.

[0047] like Figures 5 to 13 As shown, the first transmission part 22 and the second transmission part 23 are arranged at a distance from each other, and the drive part 24 is disposed between the first transmission part 22 and the second transmission part 23. In this way, by placing the drive part 24 between the first transmission part 22 and the second transmission part 23, one drive part 24 can drive the first transmission part 22 to rotate and drive the second transmission part 23 to rotate. On the one hand, this is conducive to the miniaturization design of the air duct assembly 1, and on the other hand, the structure is relatively simple, which helps to reduce the manufacturing cost of the air conditioner.

[0048] like Figures 4 to 13 As shown, the drive unit 24 includes an intermittent drive structure 241, which is rotatably disposed and has a drive region and an intermittent region. When the drive region faces the first transmission unit 22 and the intermittent region faces the second transmission unit 23, the intermittent drive structure 241 is driven connected to the first transmission unit 22 through the drive region, and the second transmission unit 23 is in an intermittent state. When the drive region faces the second transmission unit 23 and the intermittent region faces the first transmission unit 22, the intermittent drive structure 241 is driven connected to the second transmission unit 23 through the drive region, and the first transmission unit 22 is in an intermittent state. Thus, the intermittent drive structure 241 has a drive area and an intermittent area, and is rotatably arranged. When the drive area faces the first transmission part 22 and the intermittent area faces the second transmission part 23, the air guide plates 21 on both sides of the air outlet 11 rotate, while the air guide plate 21 in the middle does not rotate. When the drive area rotates to face the second transmission part 23 and the intermittent area faces the first transmission part 22, the air guide plates 21 on both sides of the air outlet 11 rotate to the maximum air outlet angle and are in an flared shape, while the air guide plate 21 in the middle starts to rotate, thus avoiding interference caused by the simultaneous rotation of the air guide plates 21.

[0049] It should be noted that in this application, the driving region includes a first sub-driving region and a second sub-driving region, the intermittent region includes a first sub-intermittent region and a second sub-intermittent region, and the intermittent driving structure 241 includes a transmission shaft 2411, a first sub-driving structure 2412, a second sub-driving structure 2413, and a drive motor 2414. The first sub-driving structure 2412 and the second sub-driving structure 2413 are connected by the transmission shaft 2411. The first sub-driving structure 2412 has a first sub-driving region and a first sub-intermittent region to intermittently drive the first transmission part 22. The second sub-driving structure 2413 has a second sub-driving region and a second sub-intermittent region to intermittently drive the second transmission part 23. The drive motor 2414 has a drive shaft 2414a, which is drivenly connected to the transmission shaft 2411 to drive the first sub-driving structure 2412 and the second sub-driving structure 2413 to rotate synchronously. In this way, the first sub-drive structure 2412 and the second sub-drive structure 2413 are connected through the transmission shaft 2411 to achieve synchronous rotation of the first sub-drive structure 2412 and the second sub-drive structure 2413. The drive motor 2414 is connected to the transmission shaft 2411 to ensure that the drive motor 2414 can drive the first sub-drive structure 2412 and the second sub-drive structure 2413 simultaneously through the transmission shaft 2411. This achieves intermittent driving of the first transmission part 22 and the second transmission part 23, ensuring the rotation reliability of each air guide plate 21.

[0050] Optionally, the intermittent drive structure 241 is integrally formed to ensure the overall structural strength of the intermittent drive structure 241.

[0051] like Figures 5 to 13 As shown, the first sub-drive region has a first tooth 2412a, and the first transmission part 22 has a first gear structure 221 for meshing with the first tooth 2412a. The first sub-intermittent region is an arc-shaped surface. Thus, when the first tooth 2412a of the first sub-drive region rotates to mesh with the first gear structure 221, the first sub-drive region drives the first gear structure 221 to rotate. When the first sub-intermittent region rotates to the side facing the first gear structure 221, the first gear structure 221 cannot mesh with the arc-shaped first sub-intermittent region, causing the first gear structure 221 to stop rotating and be at the maximum air outlet angle, thereby realizing the intermittent drive of the first gear structure 221 by the first sub-drive structure 2412.

[0052] like Figures 5 to 13 As shown, the second sub-drive region has a second tooth 2413a, and the second transmission part 23 has a second gear structure 231 for meshing with the second tooth 2413a. The second sub-intermittent region is an arc-shaped surface. Thus, when the second tooth 2413a of the second sub-drive region rotates to mesh with the second gear structure 231, the second sub-drive region drives the second gear structure 231 to rotate. When the second sub-intermittent region rotates to the side facing the second gear structure 231, the second gear structure 231 cannot mesh with the arc-shaped second sub-intermittent region, causing the second gear structure 231 to stop rotating, thereby realizing the intermittent drive of the second gear structure 231 by the second sub-drive structure 2413.

[0053] It should be noted that, in this application, apart from the two air outlet areas on both sides of the air outlet 11, the guide vanes 21 of the remaining air outlet areas can rotate independently to perform continuous air sweeping. In this way, the guide vanes 21 of the remaining air outlet areas can rotate independently to perform continuous air sweeping, enabling the air conditioner to achieve multi-directional air sweeping while delivering wide-angle air.

[0054] It should be noted that, in this application, the aforementioned continuous sweeping refers to the rotation of the guide plate 21 located in the middle during the meshing process of the second tooth 2413a and the second gear structure 231, and the rotation process achieves continuous sweeping.

[0055] Of course, apart from the two air outlet areas on both sides of the air outlet 11, the air guide plates 21 of the remaining air outlet areas in the multiple air outlet areas can be independently rotated to a preset angle for directional airflow. In this way, the air guide plates 21 of the remaining air outlet areas in the multiple air outlet areas can be independently rotated to a preset angle for directional airflow, which improves the flexibility of the rotation of the air guide plates 21 and increases the diversity of airflow guidance methods.

[0056] It should be noted that in this application, when the drive motor 2414 drives the first sub-drive structure 2412 and the second sub-drive structure 2413 to rotate synchronously to a preset angle through the transmission shaft 2411, the second tooth 2413a and the second gear structure 231 mesh and drive to the preset angle. At this time, the air guide plate 21 located in the middle stops at the preset angle, thus realizing the above-mentioned directional air guide.

[0057] like Figure 4 , Figures 9 to 11 As shown, the first sub-drive structure 2412 and the second sub-drive structure 2413 are coaxially arranged; and / or, the drive motor 2414 is coaxially arranged with the intermittent drive structure 241. In this way, while ensuring the structural compactness of the intermittent drive structure 241, it is ensured that the drive motor 2414 can drive the first sub-drive structure 2412 and the second sub-drive structure 2413 to rotate synchronously and concentrically.

[0058] like Figures 4 to 13 As shown, the position of the first sub-drive structure 2412 with its first sub-drive region is on the same side as the position of the second sub-drive structure 2413 with its second sub-drive region. Thus, when the first sub-drive region of the first sub-drive structure 2412 drives the first transmission unit 22, the second sub-interval region of the second sub-drive structure 2413 faces the second transmission unit 23. This ensures that when the guide vanes 21 on both sides of the air outlet 11 rotate, the guide vane 21 in the middle will not rotate. Similarly, when the first sub-interval region of the first sub-drive structure 2412 rotates to face the first transmission unit 22, the second sub-drive region of the second sub-drive structure 2413 rotates to face the second transmission unit 23 and is driven to connect with it, ensuring the reliability of the rotation of the guide vane 21 in the middle.

[0059] It should be noted that in this application, the first central angle of the first sub-drive region on the first sub-drive structure 2412 is C1, and the second central angle of the second sub-drive region on the second sub-drive structure 2413 is C2. The first central angle C1 and the second central angle C2 satisfy: C1 ≤ C2. This ensures that when the first tooth 2412a in the first sub-drive region disengages from the first gear structure 221 of the first transmission part 22, the second tooth 2413a in the second sub-drive region begins to drive and connect with the second gear structure 231 of the second transmission part 23. This ensures that the timing of the operation of each air guide plate 21 is different, while also ensuring the reliability of the operation of each air guide plate 21.

[0060] It should be noted that in this application, the diameter of the first gear structure 221 is larger than that of the second gear structure 231. In order to ensure that the second gear structure 231 starts to rotate while the first gear structure 221 stops rotating, the first sub-drive area and the second sub-drive area are designed such that the first central angle C1 is smaller than the second central angle C2.

[0061] Preferably, the first central angle C1 of the first sub-driving region on the first sub-driving structure 2412 is 100°; and / or, the second central angle C2 of the second sub-driving region on the second sub-driving structure 2413 is 120°. In this way, the air guide plates 21 on both sides of the air outlet 11 can rotate to the position with the largest opening angle, and at the same time as the air guide plates 21 on both sides reach the maximum position, the air guide plate 21 in the middle begins to rotate.

[0062] like Figures 4 to 13 As shown, the air guiding mechanism 20 also includes a support structure 25, which is mounted on the air outlet frame 10. Each air guide plate 21 is rotatably connected to the support structure 25 via its respective pivot shaft 211. Specifically, the pivot shafts 211 on the air guide plates 21 in the multiple air outlet areas (excluding the two air outlet areas on either side of the air outlet 11) pass through the support plate of the support structure 25 and are connected to the second gear structure 231 of the second transmission unit 23. The pivot shafts 211 on the air guide plates 21 in the two air outlet areas on either side of the air outlet 11 pass through the support plate and are connected to the two transmission linkage mechanisms 222 of the first transmission unit 22. The first gear structure 221 of the first transmission unit 22 is driven by the two transmission linkage mechanisms 222. Thus, the support structure 25 provides mounting positions for each air guide plate 21, the first transmission unit 22, and the second transmission unit 23, increasing the reliability of the connection.

[0063] like Figures 4 to 13 As shown, the support structure 25 includes a support plate 251 and a mounting plate 252. The mounting plate 252 is disposed on the support plate 251, and there is a clearance space 100 between the mounting plate 252 and the support plate 251. The first gear structure 221 is disposed on the mounting plate 252 and located at the clearance space 100. The end face of the first gear structure 221 facing the support plate 251 has two gear pivot shafts 2211. The first transmission part 22 also includes two transmission linkage mechanisms 222. One end of the two transmission linkage mechanisms 222 is used to connect with the two gear pivot shafts 2211 respectively, and the other end of the two transmission linkage mechanisms 222 is used to pivotally connect with the two air guide plates 21 at the two side edges respectively. In this way, the first gear structure 221 is mounted on the mounting plate 252, and the two gear pivot shafts 2211 of the first gear structure 221 are respectively connected to two transmission linkage mechanisms 222, so that when the first gear structure 221 rotates, it drives the two transmission linkage mechanisms 222 to move, thereby driving the air guide plates 21 located on both sides of the air outlet 11.

[0064] It should be noted that in one embodiment of this application (not shown), the support structure 25 only has a mounting plate 252, on which the air guide mechanism 20 is mounted on the air outlet frame 10, reducing the number of parts and improving assembly efficiency.

[0065] Optionally, drive motors 2414 are installed at both ends of the air outlet frame 10 to optimize the gap when the air guide plate 21 is closed.

[0066] like Figures 4 to 13 As shown, the transmission linkage mechanism 222 includes two pivotally connected sub-links 2221. The length of the sub-link 2221 connected to the first gear structure 221 is greater than the length of the sub-link 2221 connected to the air guide plate 21 at the edge. This increases the flexibility of the transmission linkage mechanism 222 by including the two pivotally connected sub-links 2221. The unequal lengths of the two sub-links 2221 allow the air guide plates 21 located on both sides of the air outlet 11 to open at their maximum angle, thus expanding the air delivery area.

[0067] It should be noted that one embodiment of the present invention is as follows:

[0068] Specifically, the air guiding mechanism 20 has three air guiding plates 21. After the air conditioner is turned on, the drive motor 2414 rotates through the drive shaft 2414a. The first sub-drive area of ​​the first sub-drive structure 2412 is driven to connect with the first transmission part 22, so as to drive the two air guiding plates 21 located at the two side edges of the three air guiding plates 21 to rotate through the first transmission part 22 until the two air guiding plates 21 located at the two side edges of the three air guiding plates 21 rotate to the maximum air outlet angle. At this point, the first sub-drive area is disengaged from the first transmission part 22, and the drive motor 2414 drives the intermittent drive structure through the drive shaft 2414a. 241 continues to rotate so that the second sub-drive area of ​​the second sub-drive structure 2413 is driven to connect with the second transmission unit 23, so that the middle air guide plate 21 among the three air guide plates 21 is driven to rotate through the second transmission unit 23. When the middle air guide plate 21 continues to move, the air sweeping function of the air conditioner is realized. When the middle air guide plate 21 is fixed at a preset angle, the directional air guide function of the air conditioner is realized. When the air conditioner stops running, the drive shaft 2414a of the drive motor 2414 rotates in the opposite direction, gradually closing each air guide plate 21 until each air guide plate 21 is completely closed and on the same arc as the outer surface on both sides of the air outlet.

[0069] It should be noted that in this application, the surface where the air outlet 11 is located is an arc surface, and each air guide plate 21 is arc-shaped. When each air guide plate 21 is in the closed state, each air guide plate 21 just closes the air outlet 11 and fits tightly.

[0070] like Figure 1As shown, the indoor unit of the air conditioner includes a decorative panel component 3, an air duct assembly 1, an evaporator component 2, an electrical box component 5, and a rear panel assembly 4.
