[0054] In the embodiments of the present application, the multiple oscillating blades are connected to the air guide plate, eliminating the spatial separation between the multiple oscillating blades and the air guide plate, making the structure more compact. This improves space utilization, reduces the space occupied by the multiple oscillating blades and the air guide plate, and facilitates the design of an ultra-thin air conditioner indoor unit. Furthermore, because the multiple oscillating blades are rotatably connected to the air guide plate, and the air guide plate and the multiple oscillating blades are driven by a first drive member and a second drive member, when the air guide plate swings, the multiple oscillating blades also swing relative to the air guide plate, thereby changing the flow direction of the airflow in front of the air guide plate. This ensures the operational performance of the air guide plate and the oscillating blades while reducing the space occupied.
[0055] Moreover, in the embodiment of the present application, because the multiple swing blades are combined with the wind guide plate, the wind guide structure can simultaneously adjust the airflow in the front of the wind guide plate in the pitch direction and the left and right directions. When the wind guide plate swings up and down, the multiple swing blades swing up and down accordingly, and can also swing left and right relative to the wind guide plate, which can expand the range of action of the swing blades. At any angle at which the wind guide plate is hovering, the swing blades can achieve a good wind sweeping effect. Compared to related technologies, the multiple swing blades in the embodiment of the present application are closer to the air outlet. The airflow adjusted by the multiple swing blades flows directly out of the air outlet, which can further improve the wind sweeping effect and enhance the user experience.
[0056] Furthermore, in the embodiment of the present application, both the first and second drive members are disposed on the mounting base, thereby integrating connecting wires and facilitating wire connection. The air guide structure of the embodiment of the present application can be manufactured as a separate component of the air conditioner indoor unit. That is, during assembly of the air conditioner indoor unit, the air guide structure can be directly connected to the housing as an independent component, thereby increasing the modularity of the air conditioner indoor unit, facilitating adjustment of the assembly process, and improving installation efficiency.

The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.
[0071] An embodiment of the present application proposes a HVAC system, which includes an outdoor unit and an air-conditioning indoor unit 1000. The outdoor unit and the air-conditioning indoor unit 1000 are connected by a pipeline, and a working medium for heat exchange circulates in the outdoor unit and the air-conditioning indoor unit 1000 through the pipeline.
[0072] Please refer to Figures 1 and 2. The outdoor unit includes a compressor and an outdoor heat exchanger, and the compressor and the outdoor heat exchanger are connected to the air-conditioning indoor unit 1000 through pipelines. The air-conditioning indoor unit 1000 can be installed in a location such as an indoor ceiling or wall to adjust the indoor temperature environment. It can take the form of a duct unit or a ceiling unit, etc., and the embodiments of the present application are not limited to this. In some embodiments, the air-conditioning indoor unit 1000 includes a casing 200, a fan 300, an indoor heat exchanger 400 and an air guide structure 100. The casing 200 is provided with an air duct 200a, and is provided with a return air port 200c and an air outlet 200b located at both ends of the air duct 200a and connected to the air duct 200a. The indoor heat exchanger 400 and the fan 300 are both arranged in the air duct 200a, and the air guide structure 100 is arranged at the air outlet 200b.
[0073] For ease of description, in this application, an up-down direction ZZ, a front-back direction YY, and a left-right direction XX are defined, and the up-down direction ZZ, the front-back direction YY, and the left-right direction XX are arranged at an angle to each other.
[0074] The housing 200 is connected to the indoor ceiling or wall and serves as a mounting base for other structural components within the air conditioner indoor unit 1000. The housing 200 can have various shapes depending on actual needs. For example, the housing 200 can be roughly rectangular for ease of installation. The housing 200 is constructed to form the aforementioned air duct 200a for air flow. The air duct 200a extends along the front-to-back direction YY. The return air port 200c is located at the rear portion of the housing 200, and the air outlet 200b is located at the front portion of the housing 200. This allows air to enter the air duct 200a through the return air port 200c, move from back to front, pass through the fan 300 and the indoor heat exchanger 400, and then flow out through the air outlet 200b.
[0075] Referring to Figure 1 , in some embodiments, to facilitate assembly, the housing 200 includes a shell 201 and a panel 202. The fan 300 and the indoor heat exchanger 400 are both mounted within the shell 201. The shell 201 and the panel 202 are connected to form the aforementioned air duct 200a. The shell 201 is provided with an air outlet 201a located on one side of the fan 300. The panel 202 is provided with the aforementioned air outlet 200b, which is connected to the air outlet 201a. The return air vent 200c can be provided on the panel 202 or the shell 201. For example, the air conditioner indoor unit 1000 is mounted on a ceiling having a mounting opening. The shell 201 is positioned above the ceiling, and the panel 202 is positioned below the shell 201 and connected to the shell 201. At least a portion of the panel 202 is exposed at the mounting opening. In this exposed portion, the air outlet 200b and the return air outlet 200c are spaced apart on the panel 202 along the front-to-back direction YY to ensure smooth return and outlet airflow. Thus, the housing 200 of the embodiment of the present application not only facilitates assembly of the air conditioner indoor unit 1000, but also allows for easy access to components such as the fan 300 and indoor heat exchanger 400 during maintenance by simply removing the panel 202, eliminating the need to completely disassemble the air conditioner indoor unit 1000, thereby improving maintenance efficiency.
[0076] In the embodiments of the present application, the housing 201 and the panel 202 can each be made of a metal material such as aluminum alloy or stainless steel to meet requirements such as high strength and corrosion resistance. Alternatively, the housing 201 and the panel 202 can also be made of a plastic material to achieve lightweighting of the air duct 200a assembly, and this application does not impose any restrictions on this. For example, a combination of a metal housing 201 and a plastic panel 202 can be employed. Furthermore, the embodiments of the present application do not impose any restrictions on the connection method between the housing 201 and the panel 202; they can be connected individually or in combination by means of snap-fitting, riveting, welding, and bolting.
[0077] The fan 300 is disposed in the air duct 200a and is capable of extracting gas from the return air outlet 200c and performing work on the gas to provide power for the gas circulation in the air duct 200a. The fan 300 can be a cross-flow fan, a centrifugal fan, an axial flow fan, or the like. As shown in FIG1 , in one embodiment, the fan 300 can be a cross-flow fan, which has the advantages of energy saving, large air volume, low noise, and simple installation. In this embodiment, the fan 300 includes an impeller and a motor. The impeller is arranged in an elongated cylindrical shape extending in the left-right direction XX. The motor is arranged at one end of the impeller and connected to the housing 200, and the output shaft of the motor is connected to the impeller. One side of the impeller is arranged generally toward the return air outlet 200c, and this side of the impeller is defined as the air inlet side; the other side of the impeller is arranged generally toward the air outlet 200b, and this side of the impeller is defined as the air outlet side. There are multiple blades distributed along the circumference of the impeller. When the motor drives the impeller to rotate, the rotating blades can cause the gas to flow from the air inlet side to the air outlet side.
[0078] The indoor heat exchanger 400 can be arranged on the side of the fan 300 close to the air outlet 200b or the side of the fan 300 close to the return air outlet 200c, and is used to exchange heat with the gas flowing through the air duct 200a and passing through the indoor heat exchanger 400, thereby cooling or heating the gas. For example, a plurality of refrigerant pipes are provided in the indoor heat exchanger 400, and the plurality of refrigerant pipes are connected to the outdoor unit, and the refrigerant flows in the indoor heat exchanger 400. When the gas passes through the indoor heat exchanger 400, the gas exchanges heat with the refrigerant in the refrigerant pipe, thereby reducing the temperature and forming low-temperature air. Optionally, in order to improve the heat exchange efficiency, the indoor heat exchanger 400 can be arranged in a shape, an arc or a wave shape, and can be composed of a single heat exchange plate, or a combination of multiple heat exchange plates. In the embodiment shown in Figure 1, the return air inlet 200c is arranged below the casing 200, and the indoor heat exchanger 400 is arranged at an angle. On the one hand, the inclined arrangement can enable the indoor heat exchanger 400 and the gas flowing through it to have a larger heat exchange area. On the other hand, it can also reduce the angle between the airflow entering from the return air inlet 200c and the indoor heat exchanger 400, so that the airflow can pass through the indoor heat exchanger 400 more smoothly, thereby further improving the heat exchange efficiency.
[0079] The air guide structure 100 is connected to the housing 200 and is located within the air outlet 201a, near the air outlet 200b, to guide the airflow at the air outlet 200b. To redirect the airflow in the vertical direction ZZ and the horizontal direction XX, the air guide structure 100 includes an air guide plate 10 and swing blades 30. The air guide plate 10 can swing in the vertical direction ZZ, and the swing blades 30 can swing in the horizontal direction XX.
[0080] In the related art, the wind guide plate and the swing blades are mostly assembled separately. For example, the swing blades are arranged on the side of the wind guide plate close to the fan. During assembly, the swing blades are first connected to the casing, and then the wind guide plate is connected to the casing. In order to avoid interference between the wind guide plate and the swing blades when they swing, there is a large distance between the wind guide plate and the swing blades to reserve sufficient swing space. In other words, the wind guide plate and the swing blades swing in different spatial parts of the air duct. In the aforementioned example, the swing blades swing left and right in the space above the wind guide plate, and the wind guide plate swings up and down in the space below the swing blades. It can be understood that the structural form of the separate and independent assembly of the wind guide plate and the swing blades in the related art occupies a large space. When faced with the ultra-thin design required for some air-conditioning indoor units (such as ceiling units), it is impossible to reduce the space occupied while ensuring the working effect of the wind guide plate and the swing blades.
[0081] In view of this, please refer to Figures 1 and 2. In some embodiments of the present application, the wind guide structure 100 includes a wind guide plate 10, a plurality of swing blades 30 and a drive assembly 50, and the drive assembly 50 is used to drive the wind guide plate 10 and the plurality of swing blades 30 to swing.
[0082] In the embodiment of the present application, the driving assembly 50 includes a first driving member 51 , a second driving member 53 and a mounting seat 55 .
[0083] The mounting base 55 is connected to the housing 200 to provide a mounting base for the first and second drive members 51 and 53. The mounting base 55 can be made of metal to ensure structural strength and support; alternatively, the mounting base 55 can be made of plastic to facilitate production and reduce weight. Optionally, the mounting base 55 is generally disc-shaped, with a mounting groove in the middle portion, in which the first and second drive members 51 and 53 are fixed. The mounting base 55 can be connected to the housing 200 on both sides by a detachable connection method such as a screw connection or a snap connection, ensuring the stability of the mounting base 55 while facilitating assembly and disassembly.
[0084] The first driving member 51 is connected to the air deflector 10 and can drive the air deflector 10 to swing along the vertical direction ZZ. For example, the first driving member 51 can be a stepping motor to facilitate precise control of the swing angle of the air deflector 10. Specifically, the first driving member 51 has an output end that can rotate about an axis extending along a first direction. In the embodiment of the present application, the first direction coincides with the left-right direction XX. The air deflector 10 is connected to the output end of the first driving member 51 so that when the output end of the first driving member 51 rotates about the axis, the air deflector 10 can also rotate about the axis extending along the first direction, thereby achieving vertical swinging of the wind.
[0085] The second drive member 53 is connected to the plurality of oscillating blades 30 and can drive the plurality of oscillating blades 30 to swing in the left-right direction XX. For example, the second drive member 53 can be a linear motor or a pneumatic cylinder having an output end that can reciprocate in a first direction. The plurality of oscillating blades 30 are connected to the output end and oscillate back and forth in the first direction accordingly. Alternatively, the second drive member 53 can be a stepper motor having a rotatable output end, which can drive the plurality of oscillating blades 30 to swing through a transmission mechanism, thereby achieving left-right airflow. This embodiment of the present application is not limited to this.
[0086] In some embodiments, the air outlet 200b is generally a strip-shaped opening extending along a first direction. Accordingly, the air deflector 10 extends along the first direction to cover as much of the air outlet 200b as possible to ensure effective air guidance. The air deflector 10 can be integrally injection molded from plastic, which offers high production efficiency and is lightweight and easy to drive. As shown in FIG2 , the air deflector 10 has a generally rectangular plate structure, one end of which is connected to the output end of the first drive member 51. The rotation of the output end of the first drive member 51 changes the angle between the air deflector 10 and the airflow at the air outlet 200b, thereby causing the air to swing up and down. For example, in the embodiment shown in FIG1 , air outlet 200b is positioned toward the bottom of housing 200. If air deflector 10 rotates clockwise about an axis extending in a first direction, the angle between air deflector 10 and the airflow at air outlet 200b increases, and air deflector 10 blocks the airflow from moving downward toward housing 200 to a certain extent, allowing the airflow to flow along air deflector 10 toward the front of housing 200. Conversely, if air deflector 10 rotates counterclockwise about an axis extending in the first direction, the angle between air deflector 10 and the airflow at air outlet 200b decreases, allowing the airflow to flow toward the bottom of housing 200 along air deflector 10. It can be understood that the greater the angle between air deflector 10 and the airflow, the greater the angle between the airflow direction and the vertical direction ZZ, and the airflow flows further toward the front of housing 200. Conversely, the smaller the angle between air deflector 10 and the airflow, the smaller the angle between the airflow direction and the vertical direction ZZ, and the airflow flows further toward the bottom of housing 200. Furthermore, to improve the stability of the air guide structure 100, a connecting shaft 17 is provided at one end of the air guide plate 10 away from the mounting base 55. The connecting shaft 17 is rotatably connected to the housing 200. Thus, by swinging the air guide plate 10, the direction of the airflow at the air outlet 200b in the pitch direction can be adjusted, and the coverage of the airflow at the air outlet 200b can be adjusted.
[0087] A plurality of swing blades 30 are rotatably connected to one side of the wind guide plate 10 and are arranged at intervals along the first direction. The swing blades 30 are roughly plate-shaped and can be made of materials such as plastic. The side of the swing blade 30 close to the wind guide plate 10 is connected to the wind guide plate 10 through a rotating shaft, and the swing blade 30 is connected to the output end of the second driving member 53. When the output end of the second driving member 53 moves, the swing blade 30 can swing around the rotating shaft relative to the wind guide plate 10 with the rotating shaft as the rotation center. The plurality of swing blades 30 are arranged at intervals to divide the airflow on one side of the wind guide plate 10 into a plurality of parts. When the plurality of swing plates rotate relative to the wind guide plate 10, the airflow moves along the swing plates and changes direction. For example, when the multiple swing blades 30 are parallel to the front-to-back direction YY, the airflow outflowing from the air outlet 200b can flow generally along the front-to-back direction YY. If the multiple swing blades 30 swing leftward relative to the air guide plate 10, the airflow outflowing from the air outlet 200b is deflected to the left of the air outlet 200b. If the multiple swing blades 30 swing rightward relative to the air guide plate 10, the airflow outflowing from the air outlet 200b is deflected to the right of the air outlet 200b. In this way, by providing multiple swing blades 30, air is swept along the left-right direction XX.
[0088] It should be noted that the first driving member 51 and the second driving member 53 can operate independently, and thus can be:
[0089] The first driving member 51 is in operation, and the second driving member 53 is inoperative. At this time, the air guide plate 10 swings, and the plurality of swing blades 30 move along with the air guide plate 10 in the swinging direction thereof, while the plurality of swing blades 30 remain stationary relative to the air guide plate 10, so as to adjust the pitch angle of the airflow while keeping the left and right directions fixed.
[0090] The first driving member 51 is not in operation, and the second driving member 53 is in operation. At this time, the air guide plate 10 is stationary, and the plurality of swing blades 30 swing left and right relative to the air guide plate 10 to adjust the left and right direction of the airflow at a fixed pitch angle.
[0091] Alternatively, the first driving member 51 and the second driving member 53 work simultaneously, then the wind guide plate 10 swings, and the multiple swing blades 30 move along the swinging direction of the wind guide plate 10, and the multiple swing blades 30 swing left and right relative to the wind guide plate 10 to simultaneously adjust the pitch angle and left and right direction of the airflow.
[0092] It is noteworthy that, compared to the related art where the swing blades 30 and the air guide plate 10 are separately provided, the multiple swing blades 30 of the embodiment of the present application are connected to the air guide plate 10, eliminating the spatial spacing between the multiple swing blades 30 and the air guide plate 10, making the structure more compact, thereby improving space utilization and reducing the space occupied by the multiple swing blades 30 and the air guide plate 10, thereby facilitating an ultra-thin design of the air conditioner indoor unit 1000. Furthermore, because the multiple air guide blades are rotatably connected to the air guide plate 10, and the air guide plate 10 and the multiple swing blades 30 are driven by the first drive member 51 and the second drive member 53, respectively, when the air guide plate 10 swings, the multiple swing blades 30 can also swing relative to the air guide plate 10, thereby changing the flow direction of the airflow in front of the air guide plate 10. This ensures the operating performance of the air guide plate 10 and the swing blades 30 while reducing the space occupied.
[0093] Furthermore, in the related art, the airflow at the air outlet 200b is typically first adjusted in the left-right direction by the oscillating blades 30 before flowing to the air guide plate 10 for adjustment in the pitch direction. During this sequential process, the diffused airflow may affect the effectiveness of the oscillating blades 30. In the present embodiment, the multiple oscillating blades 30 are integrated with the air guide plate 10, allowing the air guide structure 100 to simultaneously adjust the airflow in front of the air guide plate 10 in both the pitch and left-right directions. As the air guide plate 10 swings up and down, the multiple oscillating blades 30 also swing up and down, and can also swing left and right relative to the air guide plate 10, expanding the effective range of the oscillating blades 30. At any angle at which the air guide plate 10 hovers, the oscillating blades 30 achieve a good sweeping effect. Furthermore, compared to the related art, the multiple oscillating blades 30 in the present embodiment are closer to the air outlet 200b. The airflow adjusted by the multiple oscillating blades flows directly out of the air outlet 200b, further enhancing the sweeping effect and improving the user experience.
[0094] Furthermore, in the related art, since the wind deflector 10 and the swing blades 30 are independently mounted, the drive sources for driving the wind deflector 10 and the swing blades 30 also require independent wiring arrangements. In the present embodiment, both the first drive member 51 and the second drive member 53 are disposed on the mounting base 55, thereby integrating the connecting wires and facilitating wire connection.
[0095] Furthermore, the air guide structure 100 of the embodiments of the present application can be manufactured as a separate component of the air conditioner indoor unit 1000. That is, during assembly of the air conditioner indoor unit 1000, the air guide structure 100 can be directly connected to the housing 200 as an independent component. For example, in some embodiments, the air guide structure 100 can be assembled by connecting the mounting base 55 and the connecting shaft 17 at the other end of the air guide plate 10 to the housing 200. This improves the modularity of the air conditioner indoor unit 1000, facilitates adjustment of the assembly process, and improves installation efficiency.
[0096] In some structural forms, the panel 202 is detachably connected to the housing 201 and is provided with an air outlet 200b. The air guide structure 100 of the embodiment of the present application can be connected to the panel 202 to form a panel assembly. Optionally, the panel 202 is provided with an electrical control board. When the air guide structure 100 is connected to the panel 202, the connecting wires of the drive assembly 50 are electrically connected to the main control board, so that the main control board can provide overall control of the drive assembly 50. In this way, when assembling or installing the air conditioner indoor unit 1000, the panel assembly can be completed by simply connecting the entire panel assembly to the housing 201, further improving efficiency.
[0097] In some embodiments, the wind guide plate 10 and the plurality of swing blades 30 can be made of plastic and are integrally injection molded. The wind guide plate 10 can optionally be a single plate structure, and the plurality of swing blades 30 are rotatably connected to the wind guide plate 10. However, since the wind guide plate 10 is relatively long along the first direction, it is prone to deformation during actual use and may produce large-scale vibrations under the action of airflow, affecting the structural stability and wind-guiding performance. Therefore, referring to Figures 2 and 3, in other embodiments of the present application, the wind guide plate 10 includes a first plate body 11, a second plate body 13, and a connector 15.
[0098] Specifically, the second plate 13 is spaced apart from the first plate 11, and the second plate 13 is roughly parallel to the first plate 11. The connecting member 15 is located between the first plate 11 and the second plate 13, and connects the first plate 11 and the second plate 13. The output end of the first driving member 51 can be connected to one end of the first plate 11 or the second plate 13, so that when the output end of the first driving member 51 moves, the first plate 11 and the second plate 13 can move synchronously, and the airflow can flow along the first plate 11 and the second plate 13, and can pass between the first plate 11 and the second plate 13 to reduce the impact on the airflow. The plurality of swing blades 30 are rotatably connected to the second plate 13 to swing relative to the second plate 13. The embodiment of the present application connects the two spaced apart plates by a connecting plate, thereby increasing the constraints on the two plates, thereby effectively reducing the deformation of the wind deflector 10 and improving the stability of the wind deflector 10.
[0099] Optionally, the first plate 11 and the second plate 13 can be made of the same or different materials, for example, the first plate 11 is made of plastic and the second plate 13 is made of metal, and the first plate 11 and the second plate 13 are formed separately and then connected by a connecting piece 15; or the first plate 11, the second plate 13 and the connecting piece 15 can be integrally injection molded, with good structural integrity, high stability, light weight, and easy to drive.
[0100] Referring to Figure 3 , optionally, a direction perpendicular to the first direction is defined as a second direction, and along the second direction, the width of the first plate 11 is greater than the width of the second plate 13. The second plate 13 is disposed on one side of the first plate 11 along the first direction. In this way, the second plate 13 and the connecting member 15 can reinforce the first plate 11, reducing deformation of the first plate 11 and improving the stability of the first plate 11 while further reducing the impact on the airflow at the air outlet 200b and improving the air guiding effect.
[0101] In the embodiment of the present application, the connecting member 15 is roughly plate-shaped and extends along the front-to-back direction YY to further reduce obstruction to the airflow and ensure smoothness of the airflow.
[0102] Furthermore, referring to Figure 2 , the air deflector 10 includes at least two connectors 15 , which are spaced apart along the first direction. On the one hand, the provision of at least two connectors 15 further strengthens the constraints on the first and second plates 11 , 13 , improving their stability and reducing deformation. On the other hand, the at least two connectors 15 can divide the airflow passing between the first and second plates 11 , 13 into multiple portions, organizing these portions of airflow for easier guidance and improved airflow stability.
[0103] In conjunction with Figures 3 and 4, in the embodiment of the present application, the swing blades 30 are connected to the second plate body 13, and the plurality of swing blades 30 are arranged on the second plate body 13 at intervals along the first direction. In particular, along the first direction, the plurality of swing blades 30 can be arranged at intervals with the plurality of connectors 15. For example, the plurality of swing blades 30 can be arranged alternately with the plurality of connectors 15, with one swing blade 30 provided between two adjacent connectors 15, and an air guide channel formed between the two adjacent connectors 15, with one swing blade 30 provided in the air guide channel. In this way, the plurality of swing blades 30 can cooperate with the plurality of connectors 15 to divide at least part of the airflow at the air outlet 200b into a plurality of smaller parts, thereby facilitating the guidance of the airflow and improving the smoothness of the airflow. Of course, in other embodiments, the plurality of swing blades 30 can also be arranged in a one-to-one correspondence with the plurality of connectors 15. Under the improved concept of the present application, the embodiment of the present application does not limit this.
[0104] As shown in Figures 4 and 5, in a specific embodiment, the swing blade 30 is provided with a first plug-in post 36, and the second plate 13 is provided with a first plug-in hole 13a. The first plug-in post 36 is rotatably inserted into the first plug-in hole 13a, so that the swing blade 30 can swing relative to the second plate 13 about the central axis of the first plug-in hole 13a. The first plug-in post 36 is disposed on the side of the swing blade 30 near the second plate 13 and includes a first column 361 and a first plunger 363. The first column 361 is connected to the main portion of the swing blade 30 and extends in a direction away from the main portion. The first plunger 363 is disposed at one end of the first column 361 away from the main portion of the swing blade 30. Optionally, referring to Figure 5, the first plug-in column 36 can be made of a material with a certain elasticity such as plastic, and formed with a notch arranged along its own extension direction. This notch extends from the first plunger 363 to the first column 361, so that the first column 361 and the first plunger 363 are respectively separated into at least two parts, and each part of the first column 361 is respectively connected to a part of the first plunger 363. It can be understood that, in the natural state, at least two parts of the first plunger 363 and at least two parts of the first column 361 are spaced apart, the outer diameter of the first plunger 363 is larger than the outer diameter of the first column 361, and the outer diameter of the first column 361 is slightly smaller than the inner diameter of the first plug hole 13a; when the swing blade 30 is connected to the second plate body 13, the distance between at least two parts of the first plunger 363 can be reduced by squeezing the first plunger 363, so as to extend the first plunger 363 into the first plug hole 13a until it reaches a preset position, such as when the first plunger 363 passes through the first plug hole 13a, the first plunger 363 returns to its natural state due to its own elasticity, and thus cooperates with the second plate body 13 to limit the position, so that the first column 361 can be stably set in the first plug hole 13a, thereby completing the installation of the swing blade 30. Furthermore, to improve insertion efficiency, the first plunger 363 can be configured in a cone or frustum shape, with the outer diameter of the first plunger 363 decreasing as it moves away from the first column 361. This inclined outer surface can serve as a guide when the first plunger 363 is inserted into the first insertion hole 13a, facilitating insertion. Of course, in other embodiments, the first plunger 363 can be made of an elastic material, such as a rubber material, and integrally molded. During insertion, the first plunger 363 deforms to extend deeper into the first insertion hole 13a, and upon exiting the first insertion hole 13a, returns to its original shape, thereby engaging with the second plate 13 in a positional manner. In this manner, the embodiment of the present application connects the oscillating blade 30 to the second plate 13 through insertion, resulting in a relatively simple installation method and improved production efficiency. It is understood that the connection method between the oscillating blade 30 and the second plate 13 in the embodiment of the present application is not limited to this method and can also include a rotational connection method such as providing a plug-in column on the second plate 13 and providing a plug-in hole on the oscillating blade 30.
[0105] In the embodiment shown in Figure 3, the second plate 13 is narrower than the first plate 11 and is located on one side of the first plate 11. The first insertion hole 13a can be located on one side of the second plate 13 near the middle of the first plate 11, and the first insertion post 36 is located in the middle of the swing blade 30. This allows the swing blade 30 to be centrally mounted on the wind guide plate 10, ensuring stability and a stable swing range for the swing blade 30 and facilitating connection between the swing blade 30 and the second drive member 53.
[0106] 1 , as previously described, the air guide structure 100 is disposed within the air outlet duct 201a and adjacent to the air outlet 200b. The swing blades 30 are disposed between the front and rear side walls of the housing 200 that form the air outlet 200b. When the air conditioner indoor unit 1000 is in operation, the air guide plate 10 rotates outward, opening the air outlet 200b and allowing airflow to flow out of the air outlet 200b. In one embodiment, to prevent the swing blades 30 from interfering with the front side walls of the air outlet 200b, a distance L is maintained between the outer edges of the swing blades 30 and the side walls of the air outlet 200b when the air guide plate 10 swings, satisfying the following relationship: L ≥ 2.5 mm. It is understandable that if L is less than 2.5 mm, due to manufacturing tolerances, when the air guide plate 10 swings, the swing blades 30 may scrape the front side wall of the air outlet 200 b. This will not only generate noise and affect the service life of the housing 200, but will also cause the air guide plate 10 to operate less smoothly, making it difficult to accurately control and affecting the air guiding effect. Therefore, to avoid the above-mentioned problems, this embodiment of the present application sets the distance L between the outer edge of the swing blade 30 and the side wall of the air outlet 200 b to ≥ 2.5 mm. L can be selected to be 3 mm, 3.5 mm, etc., to avoid mutual interference between the swing blade 30 and the side wall of the air outlet 200 b, thereby ensuring the smooth movement of the air guide plate 10.
[0107] In one embodiment, the swing blade 30 includes a connected arc segment 31 and an extension segment 33. The arc segment 31 is connected to the second drive member 53 and the second plate 13. Specifically, a first plug-in post 36 is provided on the side of the arc segment 31 closest to the second plate 13 to enable the arc segment 31 to be rotatably connected to the second plate 13. The end of the arc segment 31, which is distal to the second plate 13, extends toward the other side of the first plate 11 to expand the swing range. The extension segment 33 is provided at this end of the arc segment 31, which is distal to the second plate 13.
[0108] The air guide plate 10 is rotatably connected to the housing 200 via the connecting shaft 17, and thus has a rotation axis extending along the first direction and passing through the connecting shaft 17. Optionally, the connecting shaft 17 is connected to the second plate body 13, and the rotation axis passes through the second plate body 13.
[0109] Please refer to Figure 3 again. It can be understood that when the air-conditioning indoor unit 1000 is in operation, the air guide plate 10 needs to maintain at least a certain opening of the air outlet 200b so that the air flow can flow out of the air outlet 200b along the ground. When the air guide plate 10 swings, the outer edge of the arc segment 31 is spaced apart from the front side wall at the air outlet 200b. In one embodiment, the outer edge of the arc segment 31 is arranged in an arc shape, and its arc center is arranged close to the rotation axis or is located on the rotation axis. In this way, when the swing blade 30 moves with the air guide plate 10, the distance between the outer edge of the arc segment 31 and the front side wall at the air outlet 200b changes little or remains unchanged. On the one hand, the embodiment of the present application effectively prevents interference between the outer edge of the arc segment 31 and the front sidewall at the air outlet 200b, further ensuring smooth operation of the air guide structure 100. On the other hand, because the distance between the outer edge of the arc segment 31 and the front sidewall at the air outlet 200b changes little or remains constant, the swing blade 30 can maintain a maximum swing range regardless of the angle at which the air guide plate 10 is hovering, thereby ensuring the swing effect. Furthermore, the rotation center of the swing blade 30 coincides with the arc center, further improving the swing effect.
[0110] In the embodiment of the present application, since the first plate 11 and the second plate 13 are spaced apart and have a height difference therebetween, the extension section 33 is disposed on one side of the second plate 13 along the first direction to at least guide the airflow between the first plate 11 and the second plate 13, thereby ensuring a swinging effect. It is understandable that, compared to directly connecting the swinging blade 30 to the first plate 11, connecting the arcuate section 31 to the second plate 13 can effectively shorten the distance between the outer edge of the swinging blade 30 and the center of rotation, thereby improving the stability of the swinging blade 30 during swinging. To put it another way, the extension section 33 is connected to one end of the extension section 33 and forms a notch with the arcuate section 31 on one side of the extension section 33. The second plate 13 is located in this notch. While ensuring a swinging effect, the combination of the swinging blade 30 and the wind guide plate 10 is more compact, further reducing the occupied space.
[0111] Furthermore, as shown in FIG3 , in the embodiment of the present application, the extension section 33 is connected to one end of the arc section 31 and is extended along the tangent of the end of the arc section 31. It is understandable that if the extension section 33 is still extended along the arc around the arc section 31, the portion of the extension section 33 close to the first plate 11 is narrower and has a smaller range of action during swinging. Therefore, the extension section 33 in the embodiment of the present application is extended along the tangent of the end of the arc section 31, so that the extension section 33 has a larger swinging area, can continuously guide the airflow, and has a better swinging effect. Of course, the extension section 33 may not extend along the tangent of the end of the arc section 31, or may extend along an arc with a smaller curvature than the outer edge of the arc section 31 to ensure the swinging effect of the extension section 33, which will not be elaborated here.
[0112] At the air outlet 200b, the airflow at the air outlet 200b transitions from laminar flow to turbulent flow, which easily forms larger vortices, greatly affecting aerodynamic performance and possibly generating noise. To this end, in one embodiment of the present application, a spoiler is provided on the outer edge of the swing blade 30, and the spoiler is configured to allow airflow to pass through the swing blade 30. For example, the outer edge of the swing blade 30 is provided with a plurality of spoiler holes spaced along its own circumference. The spoiler holes can be circular holes or polygonal holes, such as quadrilateral holes, hexagonal holes, etc., and each spoiler hole is provided throughout the swing blade 30, so that when the swing blade 30 in this embodiment swings, a portion of the airflow can pass through the spoiler hole, breaking up the larger vortex that would have been dissipated with the wake in advance, thereby reducing noise and improving aerodynamic performance.
[0113] Alternatively, in another embodiment, the spoiler includes a plurality of tooth structures 35 disposed on the outer edge of the swing blade 30, with the plurality of tooth structures 35 spaced apart along the circumference of the swing blade 30. Tooth-shaped slots are formed between adjacent tooth structures 35, and the plurality of tooth-shaped slots are spaced apart along the circumference of the swing blade 30. When the swing blade 30 swings, airflow can pass through the plurality of tooth-shaped slots, thereby reducing vortices and noise. The plurality of tooth structures 35 in this embodiment not only ensures the swinging effect but also facilitates the lateral flow of air at the edge of the swing blade 30, resulting in a better noise reduction effect.
[0114] In the embodiments of the present application, the cross-sectional shape of the tooth structure 35 can be triangular, rectangular, trapezoidal, semicircular, or semi-elliptical, without limitation. As shown in FIG6 , in one specific embodiment, the tooth height of the tooth structure 35 is H, satisfying the relationship: 1.5 mm ≤ H ≤ 4 mm. It is understood that, given the dimensions of the swing blade 30, the higher the tooth height, the deeper the tooth grooves on the outer edge of the swing blade 30, resulting in a smaller swing area; the lower the tooth height, the shallower the tooth grooves on the outer edge of the swing blade 30, resulting in a larger swing area. Therefore, if the tooth height H is greater than 4 mm, the swing area of the swing blade 30 may be significantly reduced, affecting the swing effect. If the tooth height H is less than 1.5 mm, the tooth grooves may be too shallow, failing to effectively disrupt the flow and thus hindering noise reduction. In summary, in order to achieve both a swing effect and noise reduction, the embodiment of the present application specifies 1.5 mm ≤ H ≤ 4 mm, and the tooth height H can be selected to be 2 mm, 3 mm, or other values.
[0115] The width of the tooth structure 35 is D, which satisfies the relationship: 1.5mm≤D≤3mm. It can be understood that, when the size specifications of the swing blade 30 are certain, the larger the width, the narrower the tooth-shaped grooves on the outer edge of the swing blade 30, and the larger the swing area; the smaller the width, the wider the tooth-shaped grooves on the outer edge of the swing blade 30, and the smaller the swing area. Therefore, if the width D is greater than 3mm, the tooth-shaped grooves may be too narrow, and may not play a good role in disturbing the flow, which is not conducive to reducing noise; if the width D is less than 1.5mm, the tooth-shaped grooves may be too wide, significantly reducing the swing area of the swing blade 30 and affecting the swing effect. In summary, in order to achieve the purpose of noise reduction while ensuring the swing effect, the embodiment of the present application limits 1.5mm≤D≤3mm, and the tooth height H can be selected to be 2mm, 2.5mm, etc.
[0116] Furthermore, the pitch angle of the multiple tooth structures 35 is Φ, satisfying the relationship: 9°≤Φ≤15°. It can be understood that, when the size specifications of the swing blade 30 are certain, the larger the pitch angle, the sparser the multiple tooth structures 35, the wider the tooth grooves on the outer edge of the swing blade 30, and the smaller the swing area; the smaller the pitch angle, the denser the multiple tooth structures 35, the narrower the tooth grooves on the outer edge of the swing blade 30, and the larger the swing area. Therefore, if the pitch angle Φ is greater than 15°, the tooth grooves may be too wide, significantly reducing the swing area of the swing blade 30 and affecting the swing effect; if the pitch angle Φ is less than 9°, the tooth grooves may be too narrow, unable to play a good role in turbulence, and not conducive to reducing noise. In summary, in order to achieve the purpose of noise reduction while ensuring the swing effect, the embodiment of the present application limits 9°≤Φ≤15°, and the pitch angle Φ can be selected as 10°, 13°, etc.
[0117] Of course, the spoiler can also adopt other possible structural forms. In some embodiments not shown, the spoiler can also be configured in a wavy shape. Specifically, the spoiler includes multiple ripples disposed on the outer edge of the swing blade 30. The ripples extend along the circumference of the swing blade 30 and undulate along the thickness of the swing blade 30. In this way, the swing blade 30 is no longer a flat plate. Instead, the ripples have a undulating structure along its thickness, which provides a better wind-breaking effect when the swing blade 30 swings, thereby reducing noise.
[0118] In some embodiments, to improve the user comfort during operation of the air conditioning indoor unit 1000, the swing angle range of the air guide plate 10 is α, satisfying the relationship 50°≤α≤60°. It should be noted that the swing angle range of the air guide plate 10 here refers to the range of movement of the air guide plate 10 when the air conditioning indoor unit 1000 is in operation. For example, when the air conditioning indoor unit 1000 is in operation, with the horizontal line as a reference, the air guide plate 10 can swing within an angle range of 20° to 20°+α with respect to the horizontal line. It is understandable that if α is less than 50°, the airflow coverage may be insufficient and the adjustment effect is not ideal; if α is greater than 60°, the airflow may blow directly downward, which may cause discomfort to the human body. Therefore, to ensure the adjustment effect and comfort, the embodiment of the present application limits 50°≤α≤60°, and α can be selected as 55°, 53°, etc.
[0119] Furthermore, the swing angle range of the swing blade 30 relative to the air guide plate 10 is β, satisfying the relationship 30°≤β≤45°. It should be noted that the swing angle range of the swing blade 30 herein refers to the range of motion of the swing blade 30 when the air conditioner indoor unit 1000 is in operation. For example, when the air conditioner indoor unit 1000 is in operation, with the vertical line as a reference, the swing blade 30 can swing within a range of -β to β relative to the vertical line. It is understandable that if β is less than 30°, the lateral coverage of the airflow may be insufficient, resulting in an unsatisfactory airflow regulation effect. If β is greater than 45°, the swing blade 30 will significantly block the airflow, hindering smooth airflow and potentially generating noise. Therefore, to ensure the regulation effect, smooth airflow, and reduce noise, the embodiment of the present application specifies 30°≤β≤45°, where β can be selected as 35°, 40°, etc.
[0120] In addition to the above-mentioned structural form in which the swing blades 30 are separately arranged and independently rotated to connect to the wind guide plate 10, in another structural form, the wind guide structure 100 also includes a connecting seat, and the connecting seat and the multiple swing blades 30 are an integral structure. The connecting seat and the wind guide plate 10 are detachably connected. For example, to facilitate disassembly and assembly, the connecting seat and the wind guide plate 10 can be connected by a snap-fit connection. The swing blades 30 can undergo elastic deformation relative to the connecting seat so that when the connecting seat is connected to the wind guide plate 10, it swings under the drive of the second driving member 53. Optionally, the swing blades 30 and the connecting seat can be integrally injection molded using PP (Polypropylene) to ensure good deformation characteristics. It can be understood that by disassembling the connecting seat, the disassembly and assembly of multiple swing blades 30 can be completed quickly, thereby improving work efficiency, and the integral molding of multiple swing blades 30 and the connecting seat can improve production efficiency.
[0121] In order to make the multiple swing blades 30 swing synchronously, the multiple swing blades 30 can be connected by transmission. The second driving member 53 is set on one side of the multiple swing blades 30 and drives one of the swing blades to swing. This swing blade drives the remaining swing blades 30 to move through transmission.
[0122] In other practical examples of the present application, the drive assembly 50 also includes a transmission assembly 57, which is connected to the output end of the second drive member 53 and is connected to the multiple swing blades 30 to drive the multiple swing blades 30 to swing synchronously relative to the wind guide plate 10.
[0123] 7 , specifically, the transmission assembly 57 includes a guide rod 571 , a sleeve 573 and a transmission rod 575 .
[0124] The guide rod 571 is connected to the second plate 13 and extends in the first direction. A sleeve 573 is slidably sleeved on the guide rod 571 and connected to the second driver 53. The second driver 53 drives the sleeve 573 to slide along the guide rod 571. To improve structural integration, the guide rod 571 is connected to the end of the second plate 13 near the mounting seat 55 and is spaced apart from the first plate 11. This shortens the distance between the sleeve 573 and the second driver 53, facilitating structural layout.
[0125] The transmission rod 575 is spaced apart from the second plate 13 and extends in the first direction. The transmission rod 575 is connected to the sleeve 573, and the plurality of swing blades 30 are rotatably connected to the transmission rod 575. When the sleeve 573 is driven by the second driving member 53 to slide along the guide rod 571, it can drive the transmission rod 575 to translate at least in the first direction, thereby causing the plurality of swing blades 30 to swing relative to the air guide plate 10.
[0126] In the embodiment of the present application, the second driving member 53 simultaneously drives the multiple swing blades 30 to swing through the sleeve 573 and the transmission rod 575, thereby improving the synchronization of the multiple swing blades 30. In addition, the cooperation between the sleeve 573 and the guide rod 571 can improve the stability of the transmission rod 575, thereby making the movement of the multiple swing blades 30 more stable and further improving the swing effect.
[0127] Optionally, a first connecting portion 5751 is provided at one end of the transmission rod 575 proximal to the second driving member 53. The sleeve 573 includes a sliding sleeve 5731 and a second connecting portion 5735. The sliding sleeve 5731 is sleeved on the guide rod 571 and connected to the output end of the second driving member 53. The second connecting portion 5735 is connected to the sliding sleeve 5731. One of the first connecting portion 5751 and the second connecting portion 5735 is provided with a connecting groove 5735a extending in a direction at an angle to the first direction. The other of the first connecting portion 5751 and the second connecting portion 5735 is provided with a connecting post extending through the connecting groove 5735a and slidable along the extending direction of the connecting groove 5735a. In this way, when the sliding sleeve 5731 and the second connecting part 5735 move along the guide rod 571, the first connecting part 5751 moves accordingly, and drives the transmission rod 575 to move, and then drives the multiple swing blades 30 to swing. The structure is simple and effective, and it is convenient to integrate the first driving member 51 and the second driving member 53 on the mounting seat 55.
[0128] In one embodiment, a avoidance groove is provided on one side of the swing blade 30 close to the second plate 13, and the guide rod 571 is movably inserted into the avoidance groove, which not only improves the stability of the guide rod 571 but also makes the structure more compact, further reducing space occupancy.
[0129] In a specific embodiment, the swing blade 30 is provided with a second plug-in column 37, and the transmission rod 575 is provided with a second plug-in hole 575a. The second plug-in column 37 is rotatably inserted into the second plug-in hole 575a, so that the swing blade 30 can rotate relative to the transmission rod 575. The second plug-in column 37 can be disposed in the avoidance groove and includes a second column 371 and a second plunger 373. The second column 371 is connected to the main portion of the swing blade 30 and extends in a direction away from the main portion. The second plunger 373 is disposed at one end of the second column 371 away from the main portion of the swing blade 30. Optionally, referring to FIG. 5 , the second plunger 373 can be made of an elastic material, such as a rubber material, and can be integrally molded. In the natural state, the outer diameter of the second plunger 373 is larger than the outer diameter of the second column 371, and the outer diameter of the second column 371 is slightly smaller than the inner diameter of the second plug hole 575a; when the swing blade 30 is connected to the transmission rod 575, the second plunger 373 can be squeezed so that the second plunger 373 can be deeply extended into the second plug hole 575a through deformation until it reaches a preset position. For example, when the second plunger 373 passes through the second plug hole 575a, the second plunger 373 returns to its natural state due to its own elasticity, and thus cooperates with the transmission rod 575 to limit the position, so that the second column 371 can be stably set in the second plug hole 575a, completing the installation of the swing blade 30. Furthermore, to improve insertion efficiency, the second plunger 373 can be configured in a cone or frustum shape, with the outer diameter of the second plunger 373 decreasing as it moves away from the second column 371. This inclined outer surface can serve as a guide when the second plunger 373 is inserted into the second insertion hole 575a, facilitating insertion. Alternatively, in other embodiments, the second insertion column 37 can be made of a material with a certain degree of elasticity, such as plastic, and have a notch formed along its extension. This notch extends from the second plunger 373 toward the second column 371, thereby separating the second column 371 and the second plunger 373 into at least two sections, with each section of the second column 371 correspondingly connected to a portion of the second plunger 373. This allows the second plunger 373 and the second column 371 to elastically expand and contract by reducing the gap, enabling quick assembly and disassembly. In this manner, the embodiment of the present application connects the swing blade 30 to the transmission rod 575 through insertion, resulting in a relatively simple installation method and improved production efficiency. It is understandable that the connection method between the swing blade 30 and the transmission rod 575 in the embodiment of the present application is not limited to this, and the transmission rod 575 can also be provided with a plug-in column, and the swing blade 30 can be provided with a plug-in hole or other rotational connection methods.
[0130] In one embodiment, to drive the sleeve 573 to move, a transmission gear 531 is provided at the output end of the second drive member 53. A rack 5733 structure extending in a first direction is provided on the outer side of the sleeve 573 (sliding sleeve 5731). The rack 5733 structure has tooth grooves 573a extending along the circumference of the guide rod 571. The transmission gear 531 engages with the rack 5733 structure, and the transmission gear 531 rotates to drive the sleeve 573 to slide along the guide rod 571. The transmission method using the gear and rack 5733 in this embodiment has high reliability and can convert the rotational motion of the output end of the second drive member 53 into the linear motion of the sleeve 573. This allows the second drive member 53 to use a drive source that facilitates precise control, such as a stepping motor, and facilitates the arrangement of the second drive member 53 within the mounting base 55, making the structure of the drive assembly 50 more compact. Furthermore, each tooth of the rack 5733 extends along the circumference of the guide rod 571, forming a plurality of tooth grooves 573a extending along the circumference of the guide rod 571. This allows the sleeve 573 to rotate with it when the air deflector 10 rotates, ensuring that the teeth of the transmission gear 531 remain within the tooth grooves 573a, thereby enhancing the stability of the transmission connection. In other embodiments of the present application, the second drive member 53 may also employ a connecting rod structure or other similar structure to drive the sleeve 573, and this embodiment of the present application is not limited thereto.
