[0075] An embodiment of the present application proposes a HVAC system, which includes an outdoor unit and an air-conditioning indoor unit 1000, wherein 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.

[0076] Please refer to Figure 1 and Figure 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 conditioner indoor unit 1000 through pipelines. The air conditioner indoor unit 1000 can be installed in a location such as an indoor ceiling or wall to adjust the indoor temperature environment. It can be in the form of a duct unit or a ceiling unit, and the embodiments of the present application are not limited to this. In some embodiments, the air conditioner 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.

[0077] 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.

[0078] The casing 200 is connected to the indoor ceiling or wall to provide a mounting base for other structural components in the air conditioner indoor unit 1000. The casing 200 can be in a variety of shapes according to actual needs. For example, the casing 200 can be roughly rectangular for easy installation. The casing 200 is structured to form the above-mentioned air duct 200a for gas flow. The air duct 200a is extended along the front-to-back direction YY, the return air port 200c is arranged at the rear part of the casing 200, and the air outlet 200b is arranged at the front part of the casing 200, so that the gas can enter the air duct 200a through the return air port 200c, and move from back to front to pass through the fan 300 and the indoor heat exchanger 400, and then flow out through the air outlet 200b.

[0079] Please refer to Figure 1 In some embodiments, for ease of assembly, the housing 200 includes a shell 201 and a panel 202, the fan 300 and the indoor heat exchanger 400 are both installed in the shell 201, and the shell 201 is connected to the panel 202 to enclose the above-mentioned air duct 200a. The shell 201 is provided with an air outlet channel 201a located on one side of the fan 300, and the panel 202 is provided with the above-mentioned air outlet 200b, which is communicated with the air outlet channel 201a, and the return air port 200c can be provided on the panel 202 or the shell 201. Exemplarily, the air conditioner indoor unit 1000 is installed on the ceiling, the ceiling is provided with a mounting port, the shell 201 is arranged above the ceiling, and the panel 202 is arranged below the shell 201 and connected to the shell 201. At least part of the panel 202 is exposed at the installation opening, and in the exposed part, the air outlet 200b and the return air outlet 200c are arranged at intervals on the panel 202 along the front-to-back direction YY to ensure smooth return and outlet air. In this way, the housing 200 of the embodiment of the present application is not only convenient for assembling the air conditioner indoor unit 1000, but also can expose components such as the fan 300 and the indoor heat exchanger 400 by directly disassembling the panel 202 during maintenance, without disassembling the entire air conditioner indoor unit 1000, thereby improving maintenance efficiency.

[0080] In the embodiment of the present application, the housing 201 and the panel 202 can be made of metal materials such as aluminum alloy or stainless steel to meet the requirements of high strength and corrosion resistance; or, the housing 201 and the panel 202 can also be made of plastic materials to achieve lightweight air duct 200a components, and the present application does not limit this. For example, the housing 201 can be made of metal material, and the panel 202 can be made of plastic material. In addition, the embodiment of the present application does not limit the connection method of the housing 201 and the panel 202, and they can be connected individually or in combination by means of clamping, riveting, welding, and bolting.

[0081] The fan 300 is disposed in the air duct 200a and is capable of extracting gas at the return air port 200c and performing work on the gas to provide power for the gas circulation in the air duct 200a. The fan 300 may be a cross-flow fan, a centrifugal fan, an axial flow fan, etc. Figure 1 As shown, in one embodiment, the fan 300 can be selected as 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 a long cylindrical shape extending along 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 in the circumferential direction is arranged roughly toward the return air port 200c, and this side of the impeller is defined as the air inlet side; the other side of the impeller in the circumferential direction, which is spaced apart from the air inlet side, is arranged roughly 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.

[0082] 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 perform heat exchange with the gas flowing through the air duct 200a and passing through the indoor heat exchanger 400, so as to cool or heat 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 passing through the indoor heat exchanger 400, the gas exchanges heat with the refrigerant in the refrigerant pipe, so that the temperature is reduced to form 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 case of Figure 1 In the illustrated embodiment, the return air inlet 200c is disposed below the casing 200, and the indoor heat exchanger 400 is disposed at an angle. On the one hand, the inclined arrangement enables the indoor heat exchanger 400 and the gas flowing therethrough to have a larger heat exchange area, and 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.

[0083] The wind guide structure 100 is connected to the housing 200 and is disposed in the air outlet channel 201a and near the air outlet 200b to guide the airflow at the air outlet 200b. In order to change the airflow direction along the up-down direction ZZ and along the left-right direction XX, the wind guide structure 100 includes a wind guide plate 10 and a swing blade 30. The wind guide plate 10 can swing along the up-down direction ZZ, and the swing blade 30 can swing along the left-right direction XX.

[0084] In the related art, the air guide plate and the swing blade are mostly assembled separately. For example, the swing blade is arranged on the side of the air guide plate close to the fan. During assembly, the swing blade is first connected to the casing, and then the air guide plate is connected to the casing. In order to avoid mutual interference between the air guide plate and the swing blade when swinging, there is a large distance between the air guide plate and the swing blade to reserve sufficient swinging space. In other words, the air guide plate and the swing blade swing in different spatial parts in the air duct. In the aforementioned example, the swing blade swings left and right in the space above the air guide plate, and the air guide plate swings up and down in the space below the swing blade. It can be understood that the structural form of the separate and independent assembly of the air guide plate and the swing blade 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 occupation while ensuring the working effect of the air guide plate and the swing blade.

[0085] In view of this, please refer to Figure 1 and Figure 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 driving assembly 50, and the driving assembly 50 is used to drive the wind guide plate 10 and the plurality of swing blades 30 to swing.

[0086] 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 .

[0087] The mounting seat 55 is connected to the housing 200 to provide a mounting base for the first driving member 51 and the second driving member 53. The mounting seat 55 can be made of metal to ensure structural strength and support; or, the mounting seat 55 can also be made of plastic to facilitate production and light weight. Optionally, the mounting seat 55 is generally disc-shaped, with a mounting groove located in the middle part, and the first driving member 51 and the second driving member 53 are fixed in the mounting groove. The two sides of the mounting seat 55 can be connected to the housing 200 by a detachable connection method such as screw connection and snap connection, which ensures the stability of the mounting seat 55 while facilitating disassembly and assembly.

[0088] The first driving member 51 is connected to the air guide plate 10, and can drive the air guide plate 10 to swing along the up-down direction ZZ. For example, the first driving member 51 can be a stepping motor, which is convenient for accurately controlling the swing angle of the air guide plate 10. Specifically, the first driving member 51 has an output end that can rotate around an axis extending along the first direction. In the embodiment of the present application, the first direction coincides with the left-right direction XX, and the air guide plate 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 around the axis, the air guide plate 10 can also rotate around the axis extending along the first direction, thereby realizing the swinging wind in the up-down direction.

[0089] The second driving member 53 is connected to a plurality of swing blades 30, and can drive the plurality of swing blades 30 to swing along the left-right direction XX. Exemplarily, the second driving member 53 can be selected as a linear motor or a cylinder, and has an output end that can reciprocate along the first direction, and the plurality of swing blades 30 are connected to the output end and swing back and forth along the first direction accordingly. Alternatively, the second driving member 53 can also adopt a stepping motor with a rotatable output end, and drive the plurality of swing blades 30 to swing by transmission, so as to realize the swinging of wind in the left-right direction, and the embodiment of the present application is not limited to this.

[0090] In some embodiments, the air outlet 200b is generally a strip-shaped opening extending along the first direction, and accordingly, the air guide plate 10 extends along the first direction to cover as much of the air outlet 200b as possible to ensure the air guiding effect. The air guide plate 10 can be made of plastic integral injection molding, which has high production efficiency and is light in weight and easy to drive. Figure 2 As shown, the wind deflector 10 has a substantially rectangular plate structure, one end of which is connected to the output end of the first driving member 51, so as to change the angle between the wind deflector 10 and the airflow at the air outlet 200b as the output end of the first driving member 51 rotates, thereby swinging the wind up and down. Figure 1In the embodiment shown, the air outlet 200b is opened toward the bottom of the housing 200. If the air guide plate 10 rotates clockwise around the axis extending along the first direction, the angle between the air guide plate 10 and the airflow at the air outlet 200b increases, and the air guide plate 10 blocks the movement of the airflow toward the bottom of the housing 200 to a certain extent, so that the airflow flows toward the front side of the housing 200 along the air guide plate 10. On the contrary, if the air guide plate 10 rotates counterclockwise around the axis extending along the first direction, the angle between the air guide plate 10 and the airflow at the air outlet 200b decreases, and the airflow can flow toward the bottom of the housing 200 along the air guide plate 10. It can be understood that the larger the angle between the air guide plate 10 and the airflow, the larger the angle between the airflow direction and the up-down direction ZZ, and the more the airflow flows toward the front of the housing 200; and the smaller the angle between the air guide plate 10 and the airflow, the smaller the angle between the airflow direction and the up-down direction ZZ, and the more the airflow flows toward the bottom of the housing 200. Furthermore, in order 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 seat 55, and the connecting shaft 17 is rotatably connected to the housing 200. In this way, the direction of the airflow at the air outlet 200b in the pitch direction can be adjusted by swinging the air guide plate 10, and the coverage range of the airflow at the air outlet 200b can be adjusted.

[0091] A plurality of swing blades 30 are rotatably connected to one side of the air guide plate 10 and are arranged at intervals along the first direction. The swing blades 30 are arranged roughly in a plate shape and can be made of materials such as plastic. The side of the swing blade 30 close to the air guide plate 10 is connected to the air 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 air 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 air guide plate 10 into a plurality of parts, and when the plurality of swing plates rotate relative to the air guide plate 10, the airflow moves along the swing plates and changes direction. For example, when the plurality of swing blades 30 are parallel to the front-rear direction YY, the airflow flowing out of the air outlet 200b can flow roughly along the front-rear direction YY; if the plurality of swing blades 30 swing to the left relative to the air guide plate 10, the airflow flowing out of the air outlet 200b flows toward the left side of the air outlet 200b, and if the plurality of swing blades 30 swing to the right relative to the air guide plate 10, the airflow flowing out of the air outlet 200b flows toward the right side of the air outlet 200b. In this way, by providing the plurality of swing blades 30, the air sweeping along the left-right direction XX is achieved.

[0092] It should be noted that the first driving member 51 and the second driving member 53 can operate independently, and thus can be:

[0093] The first driving member 51 is working, and the second driving member 53 is not working. At this time, the air guide plate 10 swings, and the plurality of swing blades 30 move along the swinging direction of the air guide plate 10, while the plurality of swing blades 30 are stationary relative to the air guide plate 10, so as to adjust the pitch angle of the airflow under the condition of a fixed left-right direction;

[0094] The first driving member 51 is not working, and the second driving member 53 is working. 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;

[0095] Alternatively, the first driving member 51 and the second driving member 53 work simultaneously, and 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.

[0096] It is worth noting that, compared with the situation in which the swing blades 30 and the air guide plate 10 are independently arranged in the related art, the multiple swing blades 30 of the embodiment of the present application are connected to the air guide plate 10, and the space interval between the multiple swing blades 30 and the air guide plate 10 is eliminated, making the structure more compact, thereby improving the space utilization rate, reducing the space occupied by the multiple swing blades 30 and the air guide plate 10, and facilitating the ultra-thin design of the air conditioner indoor unit 1000. Since 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 driving member 51 and the second driving 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 to change the flow direction of the airflow on the front side of the air guide plate 10, and the working performance of the air guide plate 10 and the swing blades 30 is guaranteed under the premise of reducing the occupied space.

[0097] Moreover, in the related art, the airflow at the air outlet 200b is usually first adjusted in the left and right direction by the swing blades 30, and then flows to the wind guide plate 10 to adjust the pitch direction. In this process, the diffused airflow may affect the effect of the swing blades 30. In the embodiment of the present application, since the plurality of swing blades 30 are combined with the wind guide plate 10, the wind guide structure 100 can simultaneously adjust the airflow in the front side of the wind guide plate 10 in the pitch direction and the left and right direction. When the wind guide plate 10 swings up and down, the plurality of swing blades 30 swing up and down accordingly, and can swing left and right relative to the wind guide plate 10, which can expand the range of action of the swing blades 30. At any angle where the wind guide plate 10 is suspended, the swing blades 30 can achieve a good wind sweeping effect. Compared with the related art, the plurality of swing blades 30 in the embodiment of the present application are closer to the air outlet 200b, and the airflow adjusted by the plurality of swing blades flows directly out of the air outlet 200b, which can further improve the wind sweeping effect and improve the user experience.

[0098] In addition, in the related art, since the air guide plate 10 and the swing blade 30 are installed separately and independently, accordingly, the driving source for driving the air guide plate 10 and the driving source for driving the swing blade 30 also need to be independently wired. In the embodiment of the present application, the first driving member 51 and the second driving member 53 are both arranged on the mounting seat 55, so that the connecting wires can be integrated to facilitate the wire connection.

[0099] Furthermore, the air guide structure 100 of the embodiment of the present application can be produced as a separate component of the air conditioner indoor unit 1000, that is, when the air conditioner indoor unit 1000 is assembled, the air guide structure 100 can be directly connected to the housing 200 as an independent component. For example, in some embodiments, the assembly of the air guide structure 100 can be completed by connecting the mounting seat 55 and the connecting shaft 17 at the other end of the air guide plate 10 to the housing 200 respectively. The modularization degree of the air conditioner indoor unit 1000 is improved, the assembly process is adjusted conveniently, and the installation efficiency is improved.

[0100] 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, an electric control board is provided on the panel 202. When the air guide structure 100 is connected to the panel 202, the connection line of the drive assembly 50 is electrically connected to the main control board so that the drive assembly 50 can be generally controlled by the main control board. In this way, when assembling or installing the air conditioner indoor unit 1000, the panel assembly can be connected to the housing 201 as a whole to complete the assembly or installation, further improving efficiency.

[0101] In some embodiments, the air guide plate 10 and the plurality of swing blades 30 may be made of plastic and are integrally injection molded. The air guide plate 10 may be a single plate structure, and the plurality of swing blades 30 are rotatably connected to the air guide plate 10. However, since the air guide plate 10 is relatively long along the first direction, it is easy to deform during actual use and may generate relatively large vibrations under the action of airflow, affecting the structural stability and air guide performance. Therefore, please refer to Figure 2 and Figure 3 In some other embodiments of the present application, the air guide plate 10 includes a first plate body 11, a second plate body 13 and a connecting member 15.

[0102] Specifically, the second plate 13 is spaced apart from the first plate 11, and the second plate 13 is substantially 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. A 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 air guide plate 10 and improving the stability of the air guide plate 10.

[0103] Optionally, the first plate body 11 and the second plate body 13 can be made of the same or different materials. For example, the first plate body 11 is made of plastic, and the second plate body 13 is made of metal. The first plate body 11 and the second plate body 13 are respectively formed and connected by the connecting piece 15; or the first plate body 11, the second plate body 13 and the connecting piece 15 can be integrally injection molded, which has good structural integrity, high stability, light weight, and is easy to drive.

[0104] Please refer 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 arranged on one side of the first plate 11 along the first direction, so that the second plate 13 and the connecting member 15 can strengthen the first plate 11, reduce the deformation of the first plate 11, improve the stability of the first plate 11, and further reduce the impact on the airflow at the air outlet 200b, thereby improving the wind guiding effect.

[0105] 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.

[0106] Furthermore, combined with Figure 2 The air guide plate 10 includes at least two connecting members 15, and the at least two connecting members 15 are arranged at intervals along the first direction. On the one hand, by providing at least two connecting members 15, the constraints on the first plate body 11 and the second plate body 13 can be further increased, the stability of the first plate body 11 and the second plate body 13 can be improved, and the deformation can be reduced; on the other hand, the at least two connecting members 15 can divide the airflow flowing between the first plate body 11 and the second plate body 13 into multiple parts, which can play a role in combing this part of the airflow, making it easier to guide and improving the stability of the airflow.

[0107] Combination Figure 3 and Figure 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. Among them, 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, and a swing blade 30 is arranged between two adjacent connectors 15, and an air guide channel is formed between two adjacent connectors 15, and a swing blade 30 is arranged 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 more and smaller parts, so as to facilitate the guidance of the airflow flow and improve the smoothness of the airflow. Of course, in other embodiments, the plurality of swing blades 30 can also be arranged one-to-one with the plurality of connectors 15. Under the improved concept of the present application, the embodiment of the present application does not limit this.

[0108] like Figure 4 and Figure 5 As shown, in a specific embodiment, the swing blade 30 is provided with a first plug-in column 36, and the second plate body 13 is provided with a first plug-in hole 13a. The first plug-in column 36 is rotatably inserted into the first plug-in hole 13a, so that the swing blade 30 can swing around the central axis of the first plug-in hole 13a relative to the second plate body 13. The first plug-in column 36 is arranged on the side of the swing blade 30 close to the second plate body 13, and includes a first column 361 and a first plunger 363. The first column 361 is connected to the main part of the swing blade 30 and extends in a direction away from the main part. The first plunger 363 is arranged at one end of the first column 361 away from the main part of the swing blade 30. Optionally, please refer to Figure 5The first plug-in column 36 can be made of a material with a certain degree of elasticity, such as plastic, and is formed with a notch arranged along its own extension direction. The 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 is at a preset position, such as when the first plunger 363 passes through the first plug hole 13a, the first plunger 363 returns to the 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, in order to improve the plug-in efficiency, the first plunger 363 can also be set in the shape of a cone or a truncated cone, and the outer diameter of the first plunger 363 becomes smaller and smaller in the direction away from the first column 361, and the inclined outer surface can play a guiding role when the first plunger 363 extends into the first plug hole 13a, so as to facilitate plug-in. Of course, in other embodiments, the first plunger 363 can also be made of elastic material, such as rubber material, and when plugging, the first plunger 363 extends deeply into the first plug hole 13a by deformation, and restores its original shape when passing through the first plug hole 13a, so as to cooperate with the second plate body 13 in a limited position. In this way, the embodiment of the present application realizes the connection of the swing blade 30 to the second plate body 13 by plug-in, and the installation method is relatively simple, which is convenient for improving production efficiency. It can be understood that the connection method between the swing blade 30 and the second plate body 13 in the embodiment of the present application is not limited to this, and it can also be a rotating connection method such as setting a plug-in column on the second plate body 13 and setting a plug-in hole on the swing blade 30.

[0109] In such Figure 3 In the illustrated embodiment, the width of the second plate body 13 is smaller than that of the first plate body 11 and is located on one side of the first plate body 11. The first plug hole 13a can be arranged on one side of the second plate body 13 close to the middle of the first plate body 11, and the first plug post 36 is arranged in the middle part of the swing blade 30, so that the swing blade 30 can be centrally installed on the wind guide plate 10, ensuring the stability and swing range of the swing blade 30, and facilitating the connection between the swing blade 30 and the second driving member 53.

[0110] Combination Figure 1As mentioned above, the air guide structure 100 is arranged in the air outlet channel 201a and is arranged near the air outlet 200b, and the swing blade 30 is arranged between the front and rear side walls of the casing 200 forming the air outlet 200b. When the air conditioner indoor unit 1000 is in operation, the air guide plate 10 is rotated out to open the air outlet 200b, and the air flow can flow out from the air outlet 200b. In one embodiment, in order to avoid interference between the swing blade 30 and the front side wall at the air outlet 200b, when the air guide plate 10 swings, there is a distance L between the outer edge of the swing blade 30 and the side wall of the air outlet 200b, and the relationship is satisfied: L ≥ 2.5mm. 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 blade 30 may scrape the front side wall of the air outlet 200b, which will not only generate noise and affect the service life of the housing 200, but also cause the air guide plate 10 to run less smoothly, making it inconvenient to precisely control and affecting the air guiding effect. Therefore, to avoid the above 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 200b to be ≥ 2.5 mm, and 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 at the air outlet 200b, and to ensure the smoothness of the movement of the air guide plate 10.

[0111] In one embodiment, the swing blade 30 includes an arc segment 31 and an extension segment 33 connected to each other. The arc segment 31 is connected to the second driving member 53 and the second plate body 13. Specifically, the first plug-in column 36 is arranged on a side of the arc segment 31 close to the second plate body 13 so that the arc segment 31 is rotatably connected to the second plate body 13. One end of the arc segment 31 away from the second plate body 13 is extended to the other side of the first plate body 11 to expand the swing range, and the extension segment 33 is arranged at the end of the arc segment 31 away from the second plate body 13.

[0112] The air guide plate 10 is rotatably connected to the housing 200 via the connecting shaft 17, and thus has a rotation axis that passes through the connecting shaft 17 and extends along the first direction. Optionally, the connecting shaft 17 is connected to the second plate body 13, and the rotation axis passes through the second plate body 13.

[0113] Please refer again Figure 3It can be understood that when the air conditioner 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 smoothly. 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 the center of the arc is arranged close to the axis of rotation or is located on the axis of rotation. 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 can effectively avoid the outer edge of the arc segment 31 from interfering with the front side wall at the air outlet 200b, further ensuring the smooth operation of the air guide structure 100; on the other hand, since the distance between the outer edge of the arc segment 31 and the front side wall at the air outlet 200b changes slightly or remains unchanged, no matter at which angle the air guide plate 10 is suspended, the swing blade 30 can ensure the maximum swing range, thereby ensuring the swing effect. Furthermore, the rotation center of the swing blade 30 coincides with the arc center, which can further improve the swing effect.

[0114] In the embodiment of the present application, since the first plate body 11 and the second plate body 13 are arranged at intervals and there is a height difference between the two, the extension section 33 is arranged on one side of the second plate body 13 along the first direction, so as to at least guide the airflow between the first plate body 11 and the second plate body 13 to ensure the swinging effect. It can be understood that compared with directly connecting the swinging blade 30 to the first plate body 11, by connecting the arc section 31 to the second plate body 13, the distance between the outer edge of the swinging blade 30 and the rotation center can be effectively shortened, thereby improving the stability of the swinging blade 30 when swinging. In other words, the extension section 33 is connected to one end of the extension section 33, and forms a notch arranged on one side of the extension section 33 with the arc section 31. The second plate body 13 is located at the notch. While ensuring the swinging effect, the combination of the swinging blade 30 and the wind guide plate 10 is relatively compact, further reducing the occupied space.

[0115] Furthermore, if Figure 3 As shown, 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 can be understood 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 has an extension along the tangent of the end of the arc section 31, so that the extension section 33 has a larger swing area, can continuously guide the airflow, and has a better swing 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 swing effect of the extension section 33, which will not be repeated here.

[0116] At the air outlet 200b, the airflow of the air outlet 200b transitions from laminar flow to turbulent flow, and it is easy to form a large vortex, which has a greater impact on aerodynamic performance and may generate noise. To this end, in one embodiment of the present application, the outer edge of the swing blade 30 is provided with a spoiler, and the spoiler is configured to allow airflow to pass through the swing blade 30. Exemplarily, the outer edge of the swing blade 30 is provided with a plurality of spoiler holes arranged at intervals along its own circumference, and the spoiler holes can be circular holes or polygonal holes, such as quadrilateral holes, hexagonal holes, etc., and each spoiler hole is arranged throughout the swing blade 30, so that the swing blade 30 in this embodiment can make a part of the airflow pass through the spoiler hole when swinging, and break up the larger vortex that was originally dissipated with the wake in advance, thereby reducing noise and improving aerodynamic performance.

[0117] Alternatively, in another embodiment, the spoiler includes a plurality of tooth structures 35 arranged on the outer edge of the swing blade 30, and the plurality of tooth structures 35 are arranged at intervals along the circumference of the swing blade 30. A tooth-shaped groove is formed between two adjacent tooth structures 35, and the plurality of tooth-shaped grooves are arranged at intervals along the circumference of the swing blade 30. When the swing blade 30 swings, the airflow can pass through the plurality of tooth-shaped grooves to achieve the effect of reducing vortices and reducing noise. The plurality of tooth structures 35 in this embodiment facilitate the lateral flow of the airflow at the edge of the swing blade 30 while ensuring the swing effect, and the noise reduction effect is better.

[0118] In the embodiment of the present application, the cross-sectional shape of the tooth structure 35 can be a triangle, a rectangle, a trapezoid, a semicircle or a semi-ellipse, which is not limited. Figure 6 As shown, in one specific embodiment, the tooth height of the tooth structure 35 is H, satisfying the relationship: 1.5mm≤H≤4mm. It can be understood that, when the size specifications of the swing blade 30 are certain, the higher the tooth height, the deeper the tooth grooves on the outer edge of the swing blade 30, and the smaller the swing area; the lower the tooth height, the shallower the tooth grooves on the outer edge of the swing blade 30, and the larger the swing area. Therefore, if the tooth height H is greater than 4mm, the swing area of ​​the swing blade 30 may be significantly reduced, affecting the swing effect; if the tooth height H is less than 1.5mm, the tooth grooves may be too shallow and cannot play a good role in disturbing the flow, which is 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 1.5mm≤H≤4mm, and the tooth height H can be selected as 2mm, 3mm, etc.

[0119] 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 cannot 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 is limited to 1.5mm≤D≤3mm, and the tooth height H can be selected as 2mm, 2.5mm, etc.

[0120] 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 groove 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 groove may be too narrow, and it may not play a good role in spoiling the flow, which is 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.

[0121] Of course, the spoiler may also adopt other possible structural forms. In some embodiments not shown in the figure, the spoiler may also be arranged in a wave shape. That is to say, the spoiler includes a plurality of corrugations arranged on the outer edge of the swing blade 30, and the plurality of corrugations extend along the circumference of the swing blade 30 and undulate along the thickness direction of the swing blade 30. In this way, the swing blade 30 is no longer a flat plate structure, but because the corrugations have high and low fluctuations in the thickness direction of the swing blade 30, it can play a better wind-breaking effect when the swing blade 30 swings, thereby reducing noise.

[0122] In some embodiments, in order to improve the user comfort when the air conditioner indoor unit 1000 is in operation, 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 conditioner indoor unit 1000 is in operation. For example, when the air conditioner indoor unit 1000 is in operation, with the horizontal line as a reference, the air guide plate 10 can swing within the range of 20° to 20°+α with the horizontal line. It can be understood that if α is less than 50°, the coverage of the air flow may not be enough and the adjustment effect is not ideal; if α is greater than 60°, the air flow may blow directly downward, which may make the human body feel uncomfortable. Therefore, in order 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.

[0123] Further, the swing angle range of the swing blade 30 on one side of 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 here refers to the range of movement 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 the range of -β to β with the vertical line. It can be understood that if β is less than 30°, the lateral coverage of the airflow may be insufficient, and the adjustment effect is not ideal; if β is greater than 45°, the swing blade 30 has a strong blocking effect on the airflow, which is not conducive to the smoothness of the air outlet and may generate noise. Therefore, in order to ensure the adjustment effect, ensure the smoothness of the air outlet, and reduce noise, the embodiment of the present application is limited to 30°≤β≤45°, and β can be selected as 35°, 40°, etc.

[0124] 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 plurality of swing blades 30 are an integral structure. The connecting seat and the wind guide plate 10 are detachably connected. For example, in order to facilitate disassembly and assembly, the connecting seat and the wind guide plate 10 can be connected by a snap-on connection. The swing blade 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 blade 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 the plurality of swing blades 30 can be completed quickly, thereby improving work efficiency, and the integral molding of the plurality of swing blades 30 and the connecting seat can improve production efficiency.

[0125] 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.

[0126] In other practical examples of the present application, the driving assembly 50 also includes a transmission assembly 57, which is connected to the output end of the second driving 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.

[0127] Combination Figure 7 Specifically, the transmission assembly 57 includes a guide rod 571 , a socket 573 and a transmission rod 575 .

[0128] The guide rod 571 is connected to the second plate 13 and extends along the first direction. The sleeve 573 is slidably sleeved on the guide rod 571 and connected to the second driving member 53. The second driving member 53 can drive the sleeve 573 to slide along the guide rod 571. In order to improve the structural integration, the guide rod 571 is connected to one end of the second plate 13 close to the mounting seat 55 and is spaced from the first plate 11 to shorten the distance between the sleeve 573 and the second driving member 53, which is convenient for structural arrangement.

[0129] The transmission rod 575 is spaced apart from the second plate body 13 and extends along 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, the transmission rod 575 can be driven to translate at least along the first direction, and the plurality of swing blades 30 can be driven to swing relative to the air guide plate 10.

[0130] The second driving member 53 of the embodiment of the present application drives the multiple swing blades 30 to swing simultaneously through the sleeve 573 and the transmission rod 575, which can improve 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, further improving the swing effect.

[0131] Optionally, a first connection portion 5751 is provided at one end of the transmission rod 575 close to the second driving member 53, and the sleeve 573 includes a sliding sleeve 5731 and a second connection 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, and the second connection portion 5735 is connected to the sliding sleeve 5731. One of the first connection portion 5751 and the second connection portion 5735 is provided with a connection groove 5735a, and the connection groove 5735a is extended in a direction that is angled with the first direction, and the other one is provided with a connection column, which is passed through the connection groove 5735a and can slide along the extension direction of the connection 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, thereby driving 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.

[0132] In one embodiment, a side of the swing blade 30 close to the second plate 13 is provided with an avoidance groove, 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.

[0133] 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 set in the avoidance groove and includes a second column 371 and a second plunger 373. The second column 371 is connected to the main part of the swing blade 30 and extends in a direction away from the main part. The second plunger 373 is set at one end of the second column 371 away from the main part of the swing blade 30. Optionally, please refer to Figure 5, the second plunger 373 can be made of elastic material, such as rubber material, and can be integrally formed. 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 to make the second plunger 373 extend deeply into the second plug hole 575a by deformation until it is at a preset position, such as when the second plunger 373 passes through the second plug hole 575a, the second plunger 373 returns to the natural state due to its own elasticity, and thus cooperates with the transmission rod 575 to limit the second column 371, so that the second column 371 can be stably set in the second plug hole 575a, and the installation of the swing blade 30 is completed. Furthermore, in order to improve the plug-in efficiency, the second plunger 373 can also be set in the shape of a cone or a truncated cone, and the outer diameter of the second plunger 373 becomes smaller and smaller in the direction away from the second column 371, and the inclined outer surface can play a guiding role when the second plunger 373 extends into the second plug hole 575a, so as to facilitate plug-in. Alternatively, in other embodiments, the second plug-in column 37 can be made of a material with a certain elasticity such as plastic, and a notch is formed along its own extension direction, and the notch extends from the second plunger 373 to the second column 371, so that the second column 371 and the second plunger 373 are respectively divided into at least two parts, and each part of the second column 371 is respectively connected to a part of the second plunger 373. As a result, the second plunger 373 and the second column 371 can be elastically retracted by reducing the interval, so as to achieve rapid disassembly and assembly. In this way, the embodiment of the present application realizes the connection of the swing blade 30 to the transmission rod 575 by plug-in, and the installation method is relatively simple, which is convenient for improving 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 it can also be a rotational connection method such as providing a plug-in column on the transmission rod 575 and providing a plug-in hole on the swing blade 30.

[0134] In one embodiment, in order to drive the sleeve 573 to move, a transmission gear 531 is provided at the output end of the second driving member 53, and a rack 5733 structure extending along the first direction is provided on the outer side of the sleeve 573 (sliding sleeve 5731), and the rack 5733 structure has a tooth groove 573a extending along the circumference of the guide rod 571, and the transmission gear 531 is meshed with the rack 5733 structure, and the transmission gear 531 rotates to drive the sleeve 573 to slide along the guide rod 571. In this embodiment, the transmission method through the gear and the rack 5733 has high reliability, and can convert the rotational motion of the output end of the second driving member 53 into the linear motion of the sleeve 573, so that the second driving member 53 can select a driving source that is easy to control accurately, such as a stepping motor, and is convenient for the arrangement of the second driving member 53 in the mounting seat 55, so that the structure of the driving assembly 50 is more compact. In addition, each tooth of the rack 5733 structure 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, so that when the air guide plate 10 rotates, the sleeve 573 rotates accordingly, and ensures that the teeth of the transmission gear 531 are still located in the tooth grooves 573a, thereby improving the stability of the transmission connection. In other embodiments of the present application, the second driving member 53 may also use a connecting rod structure to drive the sleeve 573 to move, and the present embodiment of the application is not limited to this.
