Description

Technical Field

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

[0002] Air conditioners typically have a first air guide plate installed at the air outlet to direct the airflow. Air conditioners with a zero-wind function have a second air guide plate in addition to the first air guide plate. When the first air guide plate avoids the air outlet and the second air guide plate blocks the air outlet, the airflow can be blown out through the zero-wind hole of the second air guide plate to achieve a zero-wind effect.

[0003] Existing air conditioners with zero-wind function generally require two separate drivers to drive the first and second air guide vanes to achieve independent movement of the vanes. This results in higher costs, poor structural compactness, and complex control logic.

[0004] In summary, overcoming the aforementioned shortcomings of existing air conditioners with zero-wind function is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to provide an air conditioner that alleviates the technical problems of high cost, poor structural compactness, and complex control logic of existing air conditioners with zero-wind function.

[0006] The air conditioner provided by this utility model includes an air outlet duct and an air guide assembly; the air outlet duct includes a first duct wall and a second duct wall arranged opposite to each other; the air guide assembly includes a first air guide plate and a second air guide plate, the second air guide plate has a zero air hole, the first air guide plate has a first cantilever, the second air guide plate has a second cantilever, and the second cantilever is coaxially pivotally connected to the air outlet duct with the first cantilever.

[0007] The first air guide plate is provided with a first connecting part, and the second air guide plate is provided with a second connecting part. The first connecting part and the second connecting part can be automatically connected or disconnected. When the first connecting part and the second connecting part are connected, the second air guide plate is set at an angle to the first air guide plate. The first side edge of the second air guide plate is adjacent to the first side edge of the first air guide plate. The air guide assembly can switch between a zero-wind state and a closed state.

[0008] In the zero-wind state, the second side edge of the second air guide plate is adjacent to the first air duct wall and adjacent to the air outlet edge of the air outlet duct; the second side edge of the first air guide plate is located inside the air outlet duct and adjacent to the second air duct wall, and the first air guide plate and the first air duct wall are spaced apart and opposite to each other.

[0009] In the closed state, the second air guide plate is located inside the air outlet duct, and the first air guide plate blocks the air conditioner outlet.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] When the air guide assembly is in the closed state, the first air guide plate blocks the air outlet of the air conditioner, while the second air guide plate is hidden in the air outlet duct, which can prevent dust and other debris from entering the air conditioner without affecting the appearance.

[0012] When the air guide assembly is in a zero-airflow state, the air conditioning air will not flow into the area between the first air guide plate and the second air duct wall due to the obstruction of the first air guide plate; the area between the first air guide plate and the first air duct wall can form a zero-airflow duct, and the air conditioning air can blow along the zero-airflow duct to the second air guide plate and be blown out through the zero-airflow holes on the second air guide plate to achieve the zero-airflow effect.

[0013] The process of switching from the closed state to the zero-wind state is as follows: The air guide plate rotates in the opening direction. Because the second connecting part on the second air guide plate is connected to the first connecting part on the first air guide plate, the second air guide plate can rotate synchronously with the first air guide plate until it switches to the zero-wind state. Correspondingly, in the zero-wind state, the first air guide plate and the second air guide plate can also rotate synchronously in opposite directions to switch to the closed state.

[0014] The process of switching from zero airflow state to other states is as follows: the first air guide plate rotates in the opening direction. At this time, the first connecting part and the second connecting part can automatically disengage, so that the second air guide plate stays in the current position and no longer follows the first air guide plate to rotate, so as to switch to other states; correspondingly, when it is necessary to switch back to the zero airflow state or the closed state, the first connecting part and the second connecting part can automatically connect in a suitable state so as to successfully switch to the zero airflow state or the closed state.

[0015] In this invention, the first air guide plate can be driven to rotate / sway by a drive mechanism installed inside the air conditioner housing. During the movement of the first air guide plate, the second air guide plate can be selectively driven to rotate / sway by connecting / disconnecting the first connecting part and the second connecting part, thereby achieving the switching of the corresponding position state.

[0016] Therefore, the air conditioner provided by this utility model only needs to be provided with a first connecting part and a second connecting part between the second air guide plate and the first air guide plate to realize different connection states and different relative positions of the second air guide plate and the first air guide plate. That is, the first air guide plate can selectively drive the second air guide plate to rotate / sway through the connection state of the first connecting part and the second connecting part. There is no need to set a separate drive motor to drive the second air guide plate to rotate / sway. In actual use scenarios, only one drive mechanism is needed to drive the first air guide plate to rotate / sway, so as to realize the direct drive of the first air guide plate and the indirect linkage of the second air guide plate, and complete the smooth switching of different air guiding states. This can reduce costs, improve structural compactness, and simplify control logic.

[0017] Preferably, as one possible implementation, the first air guide plate is provided with a third connecting part, and the second air guide plate is provided with a fourth connecting part. The third connecting part and the fourth connecting part can automatically connect or disconnect. When the first connecting part is connected to the second connecting part, the third connecting part and the fourth connecting part are in a disconnected state. When the third connecting part is connected to the fourth connecting part, the first connecting part and the second connecting part are in a disconnected state. A ventilation channel is formed between the first air guide plate and the second air guide plate, and the air guide assembly is in a sweeping state.

[0018] In the sweeping state, the first side edge of the first air guide plate extends beyond the air outlet of the air outlet duct, the second side edge of the first air guide plate is located inside the air outlet duct, and the first air guide plate and the second air guide plate can swing and sweep synchronously.

[0019] The beneficial effect is that it enables the air-sweeping function.

[0020] Preferably, as one possible implementation, in the air-sweeping state, the air guide assembly can rotate or remain stationary between the minimum blowing angle and the maximum blowing angle.

[0021] When the air guide assembly sweeps the air to the maximum blowing angle, it is in a wide-angle state, and the second side edge of the first air guide plate is located inside the air outlet duct and adjacent to the first air duct wall. The first air guide plate and the second air duct wall are spaced apart and opposite to each other. When the air guide assembly sweeps the air to the minimum blowing angle, it is in a narrow-angle state, and the second side edge of the first air guide plate is located inside the air outlet duct and adjacent to the second air duct wall.

[0022] When the air guide component stops at any position between the wide-angle state and the narrow-angle state, it is in the normal air outlet state.

[0023] The beneficial effect is that it can realize wide-angle blowing, narrow-angle blowing, and regular blowing functions.

[0025] The beneficial effect is that it enables the switching of the state between the first connecting part and the second connecting part, and between the third connecting part and the fourth connecting part.

[0026] Preferably, as one possible implementation, the air conditioner includes an air conditioner housing, the air conditioner housing is provided with a first limiting part and a third limiting part, and the second air guide plate is provided with a second limiting part and a fourth limiting part.

[0027] In the zero-wind state, the first limiting part can block the second limiting part to prevent the second air guide plate from rotating in the opening direction, and the first buckle can be disengaged from the first slot; in the wide-angle state, the first limiting part can block the second limiting part, and the second buckle can be engaged in the second slot; in the narrow-angle state, the third limiting part can block the fourth limiting part to prevent the second air guide plate from rotating in the closing direction, and the second buckle can be disengaged from the second slot; in the closed state, the third limiting part can block the fourth limiting part, and the first buckle can be engaged in the first slot.

[0028] The beneficial effect is that the states of the first connecting part and the second connecting part, as well as the third connecting part and the fourth connecting part, can be switched automatically without any other actions, which simplifies the structure and control logic.

[0029] Preferably, as one possible implementation, one of the first limiting portion and the second limiting portion includes a first clearance groove, and the other includes a first protrusion; the first protrusion is movable relative to the first clearance groove within the first clearance groove, and the groove wall of the first clearance groove is able to block the first protrusion.

[0030] One of the third limiting portion and the fourth limiting portion includes a second clearance groove, and the other includes a second protrusion; the second protrusion is movable relative to the second clearance groove within the second clearance groove, and the groove wall of the second clearance groove can block the second protrusion.

[0031] The beneficial effect is that it can satisfy both the rotation requirement of the second air guide plate and the obstruction requirement of the second air guide plate at a specific position.

[0033] The first air guide plate is provided with a third connecting part, and the second air guide plate is provided with a fourth connecting part. The third connecting part and the fourth connecting part can automatically connect or disconnect. When the third connecting part and the fourth connecting part are connected, a ventilation channel is formed between the first air guide plate and the second air guide plate, and the air guide assembly is at least in a sweeping state.

[0034] In the sweeping state, the first side edge of the first air guide plate extends beyond the air outlet of the air outlet duct, the second side edge of the first air guide plate is located inside the air outlet duct, and the first air guide plate and the second air guide plate can swing and sweep synchronously.

[0035] The beneficial effect is that the air conditioner provided by this utility model only needs to set a third connecting part and a fourth connecting part between the second air guide plate and the first air guide plate to realize different connection states and different relative positions of the second air guide plate and the first air guide plate. That is, the first air guide plate can selectively drive the second air guide plate to rotate / oscillate through the connection state of the third connecting part and the fourth connecting part. There is no need to set a separate drive motor to drive the second air guide plate to rotate / oscillate. In actual use scenarios, only one drive mechanism is needed to drive the first air guide plate to rotate / oscillate, which can realize the direct drive of the first air guide plate and the indirect linkage of the second air guide plate, and complete the smooth switching of different air guiding states. This can reduce costs, improve structural compactness, and simplify control logic.

[0036] Preferably, as one possible implementation, the air outlet duct includes a first duct wall and a second duct wall disposed opposite to each other.

[0037] In the sweeping state, the air guide assembly can rotate or remain stationary between the minimum blowing angle and the maximum blowing angle.

The first air guide plate and the second air duct wall are spaced apart and opposite to each other. When the air guide assembly sweeps the air to the minimum blowing angle, it is in a narrow-angle state, and the second side edge of the first air guide plate is located inside the air outlet duct and adjacent to the second air duct wall.

[0039] The beneficial effect is that it enables wide-angle blowing, narrow-angle blowing, and regular blowing functions.

[0042] Preferably, as one possible implementation, the air conditioner includes an air conditioner housing, the air conditioner housing is provided with a first limiting part and a third limiting part, and the second air guide plate is provided with a second limiting part and a fourth limiting part.

[0043] In the wide-angle state, the first limiting part can block the second limiting part, and the second buckle can be engaged in the second slot; in the narrow-angle state, the third limiting part can block the fourth limiting part to prevent the second air guide plate from rotating in the closing direction, and the second buckle can be disengaged from the second slot; one of the third limiting part and the fourth limiting part includes a second clearance groove, and the other includes a second protrusion; the second protrusion can move relative to the second clearance groove within the second clearance groove, and the groove wall of the second clearance groove can block the second protrusion.

[0063] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0064] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0065] See Figures 1a-2c This embodiment provides an air conditioner, which includes an air outlet duct 410 and an air guide assembly. The air outlet duct 410 includes a first duct wall 411 and a second duct wall 412 disposed opposite to each other. The air guide assembly includes a first air guide plate 100 and a second air guide plate 200. The second air guide plate has a zero air hole. The first air guide plate 100 has a first cantilever 110, and the second air guide plate 200 has a second cantilever 210. The second cantilever 210 is coaxially pivotally connected to the first cantilever 110 in the air outlet duct 410.

[0066] The first air guide plate 100 is provided with a first connecting part, and the second air guide plate 200 is provided with a second connecting part. The first connecting part and the second connecting part can automatically connect or disconnect. When the first connecting part and the second connecting part are connected, the second air guide plate 200 is set at an angle to the first air guide plate 100, and the first side edge of the second air guide plate 200 is adjacent to the first side edge of the first air guide plate 100. The air guide assembly can switch between a zero-wind state and a closed state.

[0067] In the zero-wind state, the second side edge of the second air guide plate 200 is adjacent to the first air duct wall 411 and the edge of the air outlet of the air outlet duct 410; the second side edge of the first air guide plate 100 is located inside the air outlet duct 410 and adjacent to the second air duct wall 412, and the first air guide plate 100 and the first air duct wall 411 are spaced apart and opposite to each other. In the closed state, the second air guide plate 200 is located in the air outlet duct 410, and the first air guide plate 100 blocks the air outlet of the air conditioner.

[0068] See Figures 1a-1c When the air guide assembly is in the closed state, the first air guide plate 100 blocks the air outlet of the air conditioner, which can block the air outlet of the air conditioner, while the second air guide plate 200 is hidden in the air outlet duct 410, which can prevent dust and other debris from entering the air conditioner and will not affect the appearance.

[0069] See Figures 2a-2cWhen the air guide assembly is in a zero-airflow state, the air conditioning air will not flow into the area between the first air guide plate 100 and the second air duct wall 412 due to the obstruction of the first air guide plate 100; while the area between the first air guide plate 100 and the first air duct wall 411 can form a zero-airflow duct, and the air conditioning air can blow along the zero-airflow duct to the second air guide plate 200 and blow out through the zero-airflow holes on the second air guide plate 200 to achieve the zero-airflow effect.

[0070] See Figures 1a-2c The process of switching from the closed state to the zero-wind state is as follows: the first air guide plate 100 rotates in the opening direction ( Figure 1a (The middle arrow indicates the direction). Because the second connecting part on the second air guide plate 200 is connected to the first connecting part on the first air guide plate 100, the second air guide plate 200 can rotate synchronously with the first air guide plate 100 until it switches to the zero-wind state. Correspondingly, in the zero-wind state, the first air guide plate 100 and the second air guide plate 200 can also rotate synchronously in opposite directions to switch to the closed state.

[0071] See Figures 2a-2c The process of switching from zero wind state to other states is as follows: The first air guide plate 100 rotates in the opening direction ( Figure 2a (The middle arrow indicates the direction). At this time, the first connecting part and the second connecting part can automatically disengage, so that the second air guide plate 200 stays in the current position and no longer rotates with the first air guide plate 100, so as to switch to other states; accordingly, when it is necessary to switch back to the zero air state or the closed state, the first connecting part and the second connecting part can automatically connect in the appropriate state so as to successfully switch to the zero air state or the closed state.

[0072] It should be noted that in this embodiment, the first air guide plate 100 can be driven to rotate / sway by the drive mechanism provided inside the air conditioner housing 400. During the movement of the first air guide plate 100, the second air guide plate 200 can be selectively driven to rotate / sway by the connection / disconnection state of the first connecting part and the second connecting part, thereby realizing the switching of the corresponding position state.

[0073] Therefore, the air conditioner provided in this embodiment only needs to provide a first connecting part and a second connecting part between the second air guide plate 200 and the first air guide plate 100 to realize different connection states and different relative positions of the second air guide plate 200 and the first air guide plate 100. That is, the first air guide plate 100 can selectively drive the second air guide plate 200 to rotate / oscillate through the connection state of the first connecting part and the second connecting part. There is no need to set a separate drive motor to drive the second air guide plate 200 to rotate / oscillate. In actual use scenarios, only one drive mechanism is needed to drive the first air guide plate 100 to rotate / oscillate, so as to realize the direct drive of the first air guide plate 100 and the indirect linkage of the second air guide plate 200, and complete the smooth switching of different air guiding states. This can reduce costs, improve structural compactness, and simplify control logic.

[0074] Furthermore, a third connecting part can be provided on the first air guide plate 100, and a fourth connecting part can be provided on the second air guide plate 200, with the third and fourth connecting parts configured to automatically connect or disconnect. Simultaneously, the third and fourth connecting parts can only connect when the first and second connecting parts are disconnected; and the first and second connecting parts can only connect when the third and fourth connecting parts are disconnected.

[0075] See Figures 2a-4c The process of switching from zero airflow to swing airflow is as follows: The first air guide plate 100 rotates in the opening direction ( Figure 2a (The middle arrow indicates the direction). The first connecting part and the second connecting part automatically disengage, causing the first air guide plate 100 and the second air guide plate 200 to separate. After separation, the first air guide plate 100 rotates independently in the opening direction, while the second air guide plate 200 remains in the separated position. Thus, the relative positions of the first air guide plate 100 and the second air guide plate 200 change. After the first air guide plate 100 rotates a certain angle, the third connecting part and the fourth connecting part automatically connect, while the first connecting part and the second connecting part remain disengaged. At this time, the air guiding assembly switches to the sweeping state.

[0076] See Figures 3a-4cWhen the air guide assembly is in the sweeping state, the first connecting part and the second connecting part are disengaged, and the third connecting part and the fourth connecting part are connected. Gaps appear between the first side edge of the second air guide plate 200 and the first side edge of the first air guide plate 100, and between the second side edge of the second air guide plate 200 and the second side edge of the first air guide plate 100, forming a ventilation channel between the first air guide plate 100 and the second air guide plate 200 for air conditioning air to be blown out. The first side edge of the first air guide plate 100 extends beyond the air outlet of the air outlet duct 410, and the second side edge of the first air guide plate 100 is located inside the air outlet duct 410. The first air guide plate 100 and the second air guide plate 200 can swing synchronously under the connection of the third connecting part and the fourth connecting part to realize the sweeping function.

[0077] See Figures 1a-1c ,as well as Figures 4a-4c The process of switching from the sweeping state to the closed state is as follows: the first guide vane 100 rotates in the closing direction ( Figure 4a (The middle arrow indicates the direction). Because the fourth connecting part on the second air guide plate 200 is connected to the third connecting part on the first air guide plate 100, the second air guide plate 200 can rotate synchronously with the first air guide plate 100. After rotating a certain angle, the third connecting part and the fourth connecting part automatically disengage. The first air guide plate 100 continues to rotate independently in the closing direction, while the second air guide plate 200 stays in the current position. When the first air guide plate 100 rotates a certain angle, the first connecting part and the second connecting part automatically connect, switching to the closed state.

[0078] In the swing mode, the air guide component can rotate or stay between the minimum and maximum air blowing angles. When the air guide component swings to the maximum air blowing angle, it is in the wide-angle mode; when the air guide component swings to the minimum air blowing angle, it is in the narrow-angle mode; when the air guide component stays at any position between the wide-angle and narrow-angle modes, it is in the normal air blowing mode. Thus, it can realize wide-angle blowing, narrow-angle blowing, and normal blowing functions.

[0079] See Figures 3a-3c In the wide-angle state, the second side edge of the first air guide plate 100 is located inside the air outlet duct 410 and adjacent to the first duct wall 411. The first air guide plate 100 and the second duct wall 412 are spaced apart and arranged opposite to each other to form a wide-angle duct, and the air conditioning air can be blown out along the wide-angle duct.

[0080] See Figures 4a-4c In the narrow angle state, the second side edge of the first air guide plate 100 is located inside the air outlet duct 410 and adjacent to the second air duct wall 412, so that the air conditioning air can be blown out along the ventilation duct.

[0081] Preferably, see Figure 1a , Figure 2a , Figure 3a and Figure 4a One of the first connecting part and the second connecting part may include a first slot 111, and the other may include a first buckle 211. The first buckle 211 and the first slot 111 can engage to allow the second air guide plate 200 to be connected to the first air guide plate 100. When the first latch 211 and the first slot 111 need to switch from a connected state to a disconnected state, resistance can be applied to the second air guide plate 200 while driving the first air guide plate 100 to rotate, causing the second air guide plate 200 to stay in its current position and no longer rotate with the first air guide plate 100. In this way, the first latch 211 can disengage from the first slot 111, realizing the state transition. Similarly, when the first latch 211 and the first slot 111 need to switch from a disconnected state to a connected state, resistance can also be applied to the second air guide plate 200 while driving the first air guide plate 100 to rotate, causing the second air guide plate 200 to stay in its current position and no longer rotate with the first air guide plate 100. In this way, the first latch 211 can be engaged into the first slot 111 from the opening of the slot, realizing the state transition.

[0082] Accordingly, see Figure 1a , Figure 2a , Figure 3a and Figure 4a One of the third connecting part and the fourth connecting part may include the second slot 112, and the other may include the second buckle 212. The second buckle 212 and the second slot 112 can be engaged to connect the second air guide plate 200 and the first air guide plate 100. When the second latch 212 and the second slot 112 need to switch from a connected state to a disconnected state, resistance can be applied to the second air guide plate 200 while driving the first air guide plate 100 to rotate, so that the second air guide plate 200 stays in its current position and no longer rotates with the first air guide plate 100. In this way, the second latch 212 can disengage from the second slot 112, realizing the state transition. Similarly, when the second latch 212 and the second slot 112 need to switch from a disconnected state to a connected state, resistance can also be applied to the second air guide plate 200 while driving the first air guide plate 100 to rotate, so that the second air guide plate 200 stays in its current position and no longer rotates with the first air guide plate 100. In this way, the second latch 212 can be engaged into the second slot 112 from the opening of the slot, realizing the state transition.

[0083] Preferably, the first slot 111 may include two opposing first spring pieces, with a first protrusion on the inner side of the first spring piece near the slot opening. Thus, after the first buckle 211 is inserted into the first slot 111, the first protrusion on the first slot 111 can block the first buckle 211, preventing it from coming out. This allows the first buckle 211 to connect with the first slot 111, enabling the first air guide plate 100 to drive the second air guide plate 200 to rotate. When the second air guide plate 200 no longer rotates with the first air guide plate 100 under external force, the first buckle 211 can overcome the blocking force of the first protrusion and come out of the slot opening of the first slot 111. This allows the first buckle 211 to separate from the first slot 111, allowing the first air guide plate 100 to rotate independently while the second air guide plate 200 remains in the separated position. It should be noted that because the first spring has strong deformation and reset capabilities, it can not only improve the connection reliability between the first air guide plate 100 and the second air guide plate 200, but also reduce the risk of jamming when the first air guide plate 100 and the second air guide plate 200 are separated.

[0084] Correspondingly, the second slot 112 may include two opposing second spring pieces. A second protrusion may be provided on the inner side of the second spring piece near the slot opening. Thus, after the second buckle 212 is inserted into the second slot 112, the second protrusion on the second slot 112 can block the second buckle 212, preventing the second buckle 212 from falling out. This allows the second buckle 212 to connect with the second slot 112 on its own, enabling the first air guide plate 100 to drive the second air guide plate 200 to rotate. When the second air guide plate 200 no longer rotates with the first air guide plate 100 under the action of external force, the second buckle 212 can overcome the blocking force of the second protrusion and fall out of the slot opening of the second slot 112. This allows the second buckle 212 to separate from the second slot 112 on its own, allowing the first air guide plate 100 to rotate independently, while the second air guide plate 200 remains in the separated position. It should be noted that because the second spring has strong deformation and reset capabilities, it can improve the connection reliability between the first air guide plate 100 and the second air guide plate 200 and reduce the risk of jamming when the first air guide plate 100 and the second air guide plate 200 are separated.

[0085] The two extreme positions of the second air guide plate 200 during its movement can be achieved by combining the limiting structure inside the air conditioner housing, so as to restrict the second air guide plate 200 to rotate / swing in the corresponding area, and use the limiting structure as the source of resistance of the second air guide plate 200.

[0086] See Figures 1a-4c A first limiting part and a third limiting part can be provided on the air conditioner housing 400, and a second limiting part and a fourth limiting part can be provided on the second air guide plate 200.

[0087] In the zero-wind state, the first limiting part can block the second limiting part to prevent the second air guide plate 200 from rotating in the opening direction. If the first air guide plate 100 rotates in the opening direction, the second air guide plate 200 cannot continue to rotate with the first air guide plate 100 under the limitation of the first limiting part. As a result, the first buckle 211 can be disengaged from the first slot 111, so that the second air guide plate 200 is separated from the first air guide plate 100. After that, the first air guide plate 100 can continue to rotate in the opening direction alone until it switches to the wide-angle state.

[0088] In the wide-angle state, the first limiting part can still block the second limiting part. Because the second air guide plate 200 is limited by the first limiting part, it will not be pushed by the first air guide plate 100. During the rotation of the first air guide plate 100, the second latch 212 will smoothly insert into the second latch 112, connecting the second air guide plate 200 to the first air guide plate 100. After the second air guide plate 200 is connected to the first air guide plate 100, the rotation of the first air guide plate 100 can drive the second air guide plate 200 to rotate synchronously with it, achieving air sweeping.

[0089] In the narrow angle state, the third limiting part can block the fourth limiting part to prevent the second air guide plate 200 from rotating in the closing direction. If the first air guide plate 100 rotates in the closing direction, the second air guide plate 200 cannot continue to rotate with the first air guide plate 100 under the limitation of the third limiting part. As a result, the second buckle 212 can be disengaged from the second slot 112, so that the second air guide plate 200 is separated from the first air guide plate 100. After that, the first air guide plate 100 can continue to rotate in the closing direction alone until it switches to the closed state.

[0090] When closed, the third limiting part can still block the fourth limiting part. The second air guide plate 200 will not be pushed by the first air guide plate 100 because it is limited by the third limiting part. During the rotation of the first air guide plate 100, the first buckle 211 will be smoothly inserted into the first slot 111, so that the second air guide plate 200 is connected to the first air guide plate 100, providing conditions for opening the air outlet later.

[0091] In this way, the states of the first connecting part and the second connecting part, as well as the third connecting part and the fourth connecting part, can be switched automatically without any other actions, which simplifies the structure and control logic.

[0092] Specifically, the second limiting part and the fourth limiting part can be provided on the second cantilever.

[0093] Preferably, one of the first limiting part and the second limiting part may include a first clearance groove 214, and the other may include a first protrusion 421. When the second air guide plate 200 rotates, the first protrusion 421 can move relative to the first clearance groove 214 within the first clearance groove 214, thereby satisfying the rotation requirements of the second air guide plate 200. When the air guide assembly switches to the zero wind state and the wide angle state, the groove wall of the first clearance groove 214 can block the first protrusion 421, thereby achieving the blocking effect of the air conditioner housing 400 on the second air guide plate 200, so that the second air guide plate 200 will not rotate with the first air guide plate 100.

[0094] Accordingly, one of the third and fourth limiting portions may include a second clearance groove 215, and the other may include a second protrusion 422. When the second air guide plate 200 rotates, the second protrusion 422 can move relative to the second clearance groove 215 within the second clearance groove 215, thereby satisfying the rotation requirements of the second air guide plate 200. When the air guide assembly switches to the closed state and the narrow angle state, the groove wall of the second clearance groove 215 can block the second protrusion 422, thereby achieving the blocking effect of the air conditioner housing 400 on the second air guide plate 200, so that the second air guide plate 200 will not rotate with the first air guide plate 100.

[0095] Specifically, the first recess 214 and the second recess 215 can both be disposed on the second air guide plate 200, and the first protrusion 421 and the second protrusion 422 can both be fixed to the cantilever of the air conditioner housing 400. Based on this, a separation structure can be provided between the first recess 214 and the second recess 215, meaning the first recess 214 and the second recess 215 are two independent grooves. This structure can improve the structural strength of the second air guide plate 200. The first protrusion 421 and the second protrusion 422 can be ribs on the air conditioner housing 400. Alternatively, the first recess 214 and the second recess 215 can be connected, meaning the first recess 214 and the second recess 215 can be two parts of the same recess.

[0096] In addition to the aforementioned snap-fit ​​and slot structures, it can also be achieved through active action. For example, an electromagnetic structure can be set at the connection between the second air guide plate 200 and the first air guide plate 100. When connection is needed, the connection is achieved by energizing and adsorption, and when disconnection is needed, the connection is achieved by de-energizing (not shown in the figure). In addition, other structures can be used to achieve the corresponding connection and disconnection, which are not limited here.

[0097] In this embodiment, a drive mechanism can be provided to drive the first air guide plate 100 to rotate. The drive mechanism can be configured to drive the first air guide plate 100 to rotate. By controlling the drive mechanism, the first air guide plate 100 can be driven.

[0098] See Figure 1b , Figure 2b , Figure 3b and Figure 4b The motor 300 can be used as the driving mechanism mentioned above. The motor 300 is connected to the first air guide plate 100, and the motor 300 can drive the first air guide plate 100 to rotate forward and in reverse.

[0099] A guide cone 430 can be installed inside the air conditioner housing 400. Two guide surfaces are arranged opposite each other on the guide cone 430, converging from the outside in to form an angled structure, with the apex of the angle facing away from the external air outlet of the air conditioner. The guide cone 430 divides the entire air outlet cavity of the air conditioner into two air outlet ducts 410, located on opposite sides of the guide cone 430. The two guide surfaces of the guide cone 430 can each form a corresponding first duct wall 411. Correspondingly, two sets of air guide components are configured, and each set is pivotally connected to one of the two air outlet ducts 410. In this way, the air conditioning air can be distributed by the guide cone 430 to the two air outlet ducts 410, and the two air guide components guide the air conditioning air within each duct, thus achieving the dual-outlet air supply requirement. In this structure, the two air guide components can be symmetrically arranged.

[0100] See Figures 3a-4c This embodiment also provides another type of air conditioner, which includes an air outlet duct 410 and an air guide assembly. The air guide assembly includes a first air guide plate 100 and a second air guide plate 200. The first air guide plate 100 has a first cantilever 110, and the second air guide plate 200 has a second cantilever 210. The second cantilever 210 is coaxially pivotally connected to the first cantilever 110 in the air outlet duct 410.

[0101] The first air guide plate 100 is provided with a third connecting part, and the second air guide plate 200 is provided with a fourth connecting part. The third connecting part and the fourth connecting part can automatically connect or disconnect. When the third connecting part and the fourth connecting part are connected, a ventilation channel is formed between the first air guide plate 100 and the second air guide plate 200, and the air guide assembly is at least in a sweeping state.

[0102] In the sweeping state, the first side edge of the first guide plate 100 extends beyond the air outlet of the air outlet duct 410, the second side edge of the first guide plate 100 is located inside the air outlet duct 410, and the first guide plate 100 and the second guide plate 200 can swing and sweep synchronously.

[0103] The air conditioner provided in this embodiment only requires a third connecting part and a fourth connecting part to be provided between the second air guide plate 200 and the first air guide plate 100, so as to realize different connection states and different relative positions of the second air guide plate 200 and the first air guide plate 100. That is, the first air guide plate 100 can selectively drive the second air guide plate 200 to rotate / oscillate through the connection state of the third connecting part and the fourth connecting part. There is no need to set a separate drive motor to drive the second air guide plate 200 to rotate / oscillate. In actual use scenarios, only one drive mechanism is needed to drive the first air guide plate 100 to rotate / oscillate, so as to realize the direct drive of the first air guide plate 100 and the indirect linkage of the second air guide plate 200, and complete the smooth switching of different air guiding states. This can reduce costs, improve structural compactness, and simplify control logic.

[0104] The air outlet duct 410 includes a first duct wall 411 and a second duct wall 412 that are disposed opposite to each other.

[0105] In the swing mode, the air guide component can rotate or stay between the minimum and maximum air blowing angles. When the air guide component swings to the maximum air blowing angle, it is in the wide-angle mode; when the air guide component swings to the minimum air blowing angle, it is in the narrow-angle mode; when the air guide component stays at any position between the wide-angle and narrow-angle modes, it is in the normal air blowing mode. Thus, it can realize wide-angle blowing, narrow-angle blowing, and normal blowing functions.

[0106] See Figures 3a-3c In the wide-angle state, the second side edge of the first air guide plate 100 is located inside the air outlet duct 410 and adjacent to the first duct wall 411. The first air guide plate 100 and the second duct wall 412 are spaced apart and arranged opposite to each other to form a wide-angle duct, and the air conditioning air can be blown out along the wide-angle duct.

[0107] See Figures 4a-4c In the narrow angle state, the second side edge of the first air guide plate 100 is located inside the air outlet duct 410 and adjacent to the second air duct wall 412, so that the air conditioning air can be blown out along the ventilation duct.

[0108] See Figure 3a and Figure 4aOne of the third connecting part and the fourth connecting part may include the second slot 112, and the other may include the second buckle 212. The second buckle 212 and the second slot 112 can be engaged to connect the second air guide plate 200 and the first air guide plate 100. When the second latch 212 and the second slot 112 need to switch from a connected state to a disconnected state, resistance can be applied to the second air guide plate 200 while driving the first air guide plate 100 to rotate, so that the second air guide plate 200 stays in its current position and no longer rotates with the first air guide plate 100. In this way, the second latch 212 can disengage from the second slot 112, realizing the state transition. Similarly, when the second latch 212 and the second slot 112 need to switch from a disconnected state to a connected state, resistance can also be applied to the second air guide plate 200 while driving the first air guide plate 100 to rotate, so that the second air guide plate 200 stays in its current position and no longer rotates with the first air guide plate 100. In this way, the second latch 212 can be engaged into the second slot 112 from the opening of the slot, realizing the state transition.

[0109] See Figures 3a-4c A first limiting part and a third limiting part can be provided on the air conditioner housing 400, and a second limiting part and a fourth limiting part can be provided on the second air guide plate 200.

[0110] In the wide-angle state, the first limiting part can still block the second limiting part. Because the second air guide plate 200 is limited by the first limiting part, it will not be pushed by the first air guide plate 100. During the rotation of the first air guide plate 100, the second latch 212 will smoothly insert into the second latch 112, connecting the second air guide plate 200 to the first air guide plate 100. After the second air guide plate 200 is connected to the first air guide plate 100, the rotation of the first air guide plate 100 can drive the second air guide plate 200 to rotate synchronously with it, achieving air sweeping.

[0111] In the narrow angle state, the third limiting part can block the fourth limiting part to prevent the second air guide plate 200 from rotating in the closing direction. If the first air guide plate 100 rotates in the closing direction, the second air guide plate 200 cannot continue to rotate with the first air guide plate 100 under the limitation of the third limiting part. As a result, the second buckle 212 can be disengaged from the second slot 112, so that the second air guide plate 200 is separated from the first air guide plate 100. After that, the first air guide plate 100 can continue to rotate in the closing direction alone until it switches to the closed state.

[0112] In this way, the states of the third and fourth connecting parts can be switched automatically without any other actions, which simplifies the structure and control logic.

[0113] One of the aforementioned third and fourth limiting portions may include a second clearance groove 215, and the other may include a second protrusion 422. When the second air guide plate 200 rotates, the second protrusion 422 can move relative to the second clearance groove 215 within the second clearance groove 215, thereby satisfying the rotation requirements of the second air guide plate 200. When the air guide assembly switches to the closed state and the narrow angle state, the groove wall of the second clearance groove 215 can block the second protrusion 422, thereby achieving the blocking effect of the air conditioner housing 400 on the second air guide plate 200, so that the second air guide plate 200 will not rotate with the first air guide plate 100.

[0114] In summary, compared to existing air conditioners that use separate drive motors to control the rotation / swing of the second air guide plate 200 and the first air guide plate 100, the air conditioner provided in this embodiment, through the arrangement of the first connecting part, the second connecting part, the third connecting part, and the fourth connecting part, can selectively realize the linkage and relative position between the second air guide plate 200 and the first air guide plate 100. It eliminates the need for a separate drive motor to drive the rotation / swing of the second air guide plate 200; by simply using a drive motor to drive the rotation / swing of the first air guide plate 100, the first air guide plate 100 can selectively drive the second air guide plate 200 to rotate / swing within a preset area. This allows for switching between corresponding states such as closed state, zero-wind state, wide-angle state, and narrow-angle state, smoothly switching between different air guiding states. This design features high structural compactness, reduced costs, and simplified control logic.
