Description

Technical Field

[0001] This invention relates to the field of air handling equipment technology, and in particular to a diffuser assembly and an air conditioner. Background Technology

[0002] In related technologies, with the improvement of living standards, consumers are paying more and more attention to the user experience of consumer products. In the air conditioning field, users not only have requirements for cooling and heating performance, but also increasingly higher requirements for the comfort and overall experience of air conditioners. For example, a single air supply method such as vertical airflow is no longer sufficient to meet user needs. When the indoor temperature is constant, when the air conditioner's airflow, especially the cold air, blows directly onto a person's body, the user will feel uncomfortable, greatly reducing the comfort of the air conditioner and the user's overall experience. Summary of the Invention

The second air diffuser blade is sleeved outside the first air diffuser blade and rotates relative to it. This improves the turbulence state during airflow and reduces the airflow velocity, thereby improving the smoothness of airflow.

[0062] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0064] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0065] The following description, with reference to the accompanying drawings, describes an air diffuser assembly 100 according to an embodiment of the present invention.

[0066] like Figures 3-8 and Figures 13-18 As shown, the air diffuser assembly 100 according to an embodiment of the present invention includes a mounting frame 1 and a blade assembly 2.

[0067] Among them, there are multiple blade assemblies 2 and they are along the length direction of the mounting frame 1 (e.g., Figure 3 and Figure 13 The blade assembly 2 includes a first air diffuser blade 21 and a second air diffuser blade 22, arranged at intervals in the x direction shown. At least one of the first air diffuser blade 21 and the second air diffuser blade 22 is rotatably mounted on the mounting frame 1, and the second air diffuser blade 22 is sleeved outside the first air diffuser blade 21 and rotates relative to it.

[0068] It is understandable that the two opposite ends of the mounting frame 1 are the air inlet and the air outlet, respectively. The airflow enters the diffuser assembly 100 through the air inlet. The first diffuser blade 21 and the second diffuser blade 22 of the multiple blade assemblies 2 cut, disperse and divert the airflow, thereby improving the turbulence state during the airflow process. At the same time, it can reduce the airflow velocity and improve the smoothness of the airflow, so that the airflow blown from the air outlet will not blow directly to the user, which can improve the comfort of the airflow and achieve the effect of a breeze or no wind in the diffuser assembly 100.

[0069] Meanwhile, by having the second diffuser blade 22 mounted outside the first diffuser blade 21 and rotating relative to it, the second diffuser blade 22 further disperses and recombines the airflow generated by the first diffuser blade 21, forming a mixed diffused airflow, thereby achieving more thorough airflow dispersion. This allows the airflow to be more fully dispersed to all corners of the space, thus expanding the range of airflow dispersion. Furthermore, the process of airflow dispersion and recombination makes the airflow more uniform and gentle, further reducing the impact and directness of the airflow, and effectively improving the windless feeling index and windless feeling airflow volume.

[0070] In addition, by having multiple blade assemblies 2 arranged at intervals along the length of the mounting frame 1, the airflow entering the diffuser assembly 100 through the air inlet is dispersed by multiple blade assemblies 2, reducing the phenomenon of excessively high local wind speed, making the wind speed in the entire diffuser area more balanced, and effectively improving the diffuser efficiency of the diffuser assembly 100.

[0071] For example, the first diffuser blade 21 is rotatably mounted on the mounting frame 1, and the second diffuser blade 22 is fixedly connected to the mounting frame 1; or, the second diffuser blade 22 is rotatably mounted on the mounting frame 1, and the first diffuser blade 21 is fixedly connected to the mounting frame 1; or, both the first diffuser blade 21 and the second diffuser blade 22 are rotatably mounted on the mounting frame 1, and their rotation directions are opposite; or, both the first diffuser blade 21 and the second diffuser blade 22 are rotatably mounted on the mounting frame 1, and their rotation directions are the same but their rotation speeds are different. Thus, through these various combinations, the second diffuser blade 22 and the first diffuser blade 21 can rotate relative to each other, achieving different airflow effects from the airflow assembly 100 and meeting different user needs.

[0072] According to an embodiment of the present invention, the air diffuser assembly 100 has multiple blade assemblies 2 arranged at intervals along the length of the mounting frame 1. Each blade assembly 2 includes a first air diffuser blade 21 and a second air diffuser blade 22. At least one of the first air diffuser blade 21 and the second air diffuser blade 22 is rotatably mounted on the mounting frame 1. The second air diffuser blade 22 is sleeved outside the first air diffuser blade 21 and rotates relative to it. This improves the turbulence state during the airflow process and reduces the airflow velocity, thereby improving the smoothness of the airflow. This prevents the airflow blown from the air diffuser assembly 100 from blowing directly at the user, thus improving the comfort of the airflow and achieving a breeze-like or windless effect from the air diffuser assembly 100.

[0073] In some embodiments of the present invention, such as Figure 13 As shown, the first air diffuser blade 21 is rotatably mounted on the mounting frame 1, and the blade assembly 2 also includes a first drive device 24. The first drive device 24, mounted on the mounting frame 1, is used to drive the first air diffuser blade 21 to rotate.

[0074] Therefore, by driving the first diffuser blade 21 to rotate through the first drive rotation, the airflow through the diffuser assembly 100 will change its direction and form a vortex under the action of the first diffuser blade 21. This makes the airflow direction entering the first diffuser blade 21 inconsistent with the airflow direction leaving the first diffuser blade 21, thus changing the airflow from a direct blowing wind to a swirling wind. This improves the turbulence state during the airflow process, while also reducing the airflow velocity and improving the smoothness of the airflow. This prevents the airflow from blowing directly at the user after passing through the diffuser assembly 100, thereby improving the comfort of the airflow and achieving a breeze-like or windless effect from the diffuser assembly 100.

[0075] Meanwhile, the mounting frame 1 provides a solid support for the first drive device 24, ensuring that the first drive device 24 can stably drive the first air diffuser blade 21 to rotate, thereby improving the reliability and safety of the air diffuser assembly 100.

[0076] In some embodiments of the present invention, such as Figure 5 , Figure 6 and Figures 13-18 As shown, the first drive device 24 includes a first motor 241 and a plurality of first conveyor belts 242. The first motor 241 is mounted on the mounting frame 1, and the first rotation shafts 211 of any two adjacent first air diffuser blades 21 are driven by the first conveyor belts 242. The first motor 241 and the first rotation shaft 211 of one of the first air diffuser blades 21 are driven by the first conveyor belts 242.

[0077] Therefore, when the first motor 241 rotates, the first motor 241 drives the first diffuser blades 21, which are connected to the first motor 241 via the first conveyor belt 242, to rotate. Furthermore, any two adjacent first diffuser blades 21 are driven by the first conveyor belt 242, causing the other first diffuser blades 21 to rotate sequentially via the first conveyor belt 242, thus enabling the first drive device 24 to drive the first diffuser blades 21 to rotate. Simultaneously, the mounting frame 1 provides stable support for the first motor 241, ensuring that the first motor 241 can stably drive each first diffuser blade 21 to rotate via multiple first conveyor belts 242, improving the reliability and safety of the diffuser assembly 100.

[0078] Compared with the traditional gear transmission structure, the transmission structure composed of the first motor 241 and multiple first conveyor belts 242 is simpler, easier to install and maintain, occupies less space, and has the advantages of low cost. At the same time, the contact area between the conveyor belt and the air is relatively small, which reduces its wind resistance. In addition, the first motor 241 and multiple first conveyor belts 242 have the advantage of high transmission efficiency.

[0079] In some embodiments of the present invention, such as Figure 16 As shown, the first rotating shaft 211 has a first groove 2111 extending in the circumferential direction of the first rotating shaft 211, and the first conveyor belt 242 is wound around the first groove 2111. This arrangement increases the contact area between the first conveyor belt 242 and the first rotating shaft 211, thereby enhancing their friction and enabling the first conveyor belt 242 to more effectively transmit torque and speed, ensuring that the first motor 241 can stably drive each first diffuser blade 21 to rotate via multiple first conveyor belts 242.

[0080] In some embodiments of the present invention, the first conveyor belt 242 is a V-belt. It is understood that since the cross-sectional shape of the V-belt is trapezoidal and the working surface is two sides, it has a large working contact surface. Therefore, by making the first conveyor belt 242 a V-belt, the friction between the first conveyor belt 242 and the first rotating shaft 211 is enhanced, so that the first conveyor belt 242 can transmit torque and speed more effectively, ensuring that the first motor 241 can stably drive each first diffuser blade 21 to rotate through multiple first conveyor belts 242.

[0081] In some embodiments of the present invention, such as Figures 13-16 As shown, the first air diffuser blade 21 includes a first rotating shaft 211 and a first blade 212. The first rotating shaft 211 is rotatably mounted on the mounting frame 1, and the first driving device 24 drives the first rotating shaft 211 to rotate. The first blades 212 are disposed on the first rotating shaft and are a plurality of blades spaced apart along the circumferential direction of the first rotating shaft.

[0082] It is understood that the first drive device 24 drives the first rotating shaft 211 to rotate, so that the first rotating shaft 211 rotates and drives multiple first blades 212 to rotate, thereby realizing the rotation of the first diffuser blades 21. This causes the airflow to change direction and form a vortex under the action of multiple first blades 212, so that the airflow in the direction of entering the first diffuser blades 21 is not the same as the airflow out of the first diffuser blades 21, thereby changing the airflow from direct blowing wind to vortex wind.

[0083] In some embodiments of the present invention, the second diffuser blade 22 is fixedly connected to the mounting frame 1. It is understood that by fixing the second diffuser blade 22 to the mounting frame 1, the second diffuser blade 22 remains stationary, thus fixing the direction of the airflow generated by the second diffuser blade 22, thereby allowing the first diffuser blade 21 and the second diffuser blade 22 to rotate relative to each other. Therefore, when the airflow passes through the blade assembly 2, the rotation of the first diffuser blade 21 causes the airflow to change direction and form a vortex, and the second diffuser blade 22, located outside the first diffuser blade 21, further guides the airflow generated by the first diffuser blade 21, thereby enhancing or changing the diffusion direction and range of the airflow.

[0084] In some embodiments of the present invention, such as Figure 5 , Figure 6 and Figure 13 As shown, the second air diffuser blade 22 is rotatably mounted on the mounting frame 1. The air diffuser assembly 100 also includes a second drive device 25, which is mounted on the mounting frame 1 and is used to drive the second air diffuser blade 22 to rotate.

[0085] Therefore, the second drive device 25 drives the second diffuser blade 22 to rotate, causing the airflow through the diffuser assembly 100 to change direction and form a vortex under the action of the second diffuser blade 22. This makes the airflow direction entering the second diffuser blade 22 inconsistent with the airflow direction leaving the second diffuser blade 22, transforming the airflow from a direct blowing wind into a swirling wind. At the same time, the relative rotation of the first diffuser blade 21 and the second diffuser blade 22 further enhances the turbulence state during the airflow process, while reducing the airflow velocity and improving the smoothness of the airflow. This prevents the airflow from blowing directly at the user after passing through the diffuser assembly 100, improving the comfort of the airflow and achieving a breeze-like or windless effect from the diffuser assembly 100.

[0086] Meanwhile, the mounting frame 1 provides a solid support for the second drive device 25, ensuring that the second drive device 25 can stably drive the second diffuser blade 22 to rotate, thereby improving the reliability and safety of the diffuser assembly 100.

[0087] Specifically, when the first diffuser blade 21 and the second diffuser blade 22 rotate in opposite directions, they direct the airflow in opposite directions, further enhancing the turbulence and reducing the impact of the airflow. This makes it more effective in achieving a gentle breeze or no breeze effect on the airflow exiting the diffuser assembly 100. Alternatively, when the first diffuser blade 21 and the second diffuser blade 22 rotate in the same direction but at different speeds, they can achieve airflow over a longer distance while simultaneously dispersing air, thus increasing the airflow distance and range of the diffuser assembly 100.

[0088] In some embodiments of the present invention, such as Figure 5 , Figure 6 and Figures 13-18 As shown, the second drive device 25 includes a second motor 251 and multiple second conveyor belts 252. The second motor 251 is mounted on the mounting frame 1, and the second rotation shafts 222 of any two adjacent second air diffuser blades 22 are driven by the second conveyor belts 252. The second motor 251 and the second rotation shaft 222 of one of the second air diffuser blades 22 are driven by the second conveyor belts 252.

[0089] Therefore, when the second motor 251 rotates, the second motor 251 drives the second diffuser blades 22, which are connected to the second motor 251 via the second conveyor belt 252, to rotate. Furthermore, any two adjacent second diffuser blades 22 are driven by the second conveyor belt 252, causing other second diffuser blades 22 to rotate sequentially via the second conveyor belt 252, thus enabling the second drive device 25 to drive the second diffuser blades 22 to rotate. Simultaneously, the mounting frame 1 provides stable support for the second motor 251, ensuring that the second motor 251 can stably drive each second diffuser blade 22 to rotate via multiple second conveyor belts 252, improving the reliability and safety of the diffuser assembly 100.

[0090] Compared with the traditional gear transmission structure, the transmission structure composed of the second motor 251 and multiple second conveyor belts 252 is simpler, easier to install and maintain, occupies less space, and has the advantages of low cost. At the same time, the contact area between the conveyor belt and the air is relatively small, which reduces its wind resistance. In addition, the second motor 251 and multiple second conveyor belts 252 have the advantage of high transmission efficiency.

[0091] Furthermore, the first motor 241 and the second motor 251 are located on opposite sides along the length of the blade assembly 2. The first motor 241 is driven by the first rotating shaft 211 of the first diffuser blade 21 closest to the first motor 241 via the first conveyor belt 242, and the second motor 251 is driven by the second rotating shaft 222 of the second diffuser blade 22 closest to the second motor 251 via the second conveyor belt 252. This arrangement avoids mutual interference between the first motor 241 and the second motor 251, while also making the layout of the multiple first conveyor belts 242 and second conveyor belts 252 more reasonable, ensuring transmission reliability, and simplifying the structure of the diffuser assembly 100.

[0092] In some embodiments of the present invention, such as Figure 16 As shown, the second rotating shaft 222 has a second groove 2221 extending in the circumferential direction of the second rotating shaft 222, and the second conveyor belt 252 is wound around the second groove 2221. This arrangement increases the contact area between the second conveyor belt 252 and the second rotating shaft 222, thereby enhancing their friction and enabling the second conveyor belt 252 to more effectively transmit torque and speed, ensuring that the second motor 251 can stably drive each second diffuser blade 22 to rotate via multiple second conveyor belts 252.

[0093] In some embodiments of the present invention, the second conveyor belt 252 is a V-belt. It is understood that because the cross-sectional shape of a V-belt is trapezoidal and its working surface consists of two sides, it has a large working contact surface. Therefore, by making the second conveyor belt 252 a V-belt, the friction between the second conveyor belt 252 and the second rotating shaft 222 is enhanced, allowing the second conveyor belt 252 to transmit torque and speed more effectively, ensuring that the second motor 251 can stably drive each second diffuser blade 22 to rotate via multiple second conveyor belts 252.

[0094] In some embodiments of the present invention, such as Figure 16 and Figure 18 As shown, the second diffuser blade 22 includes a first body portion 221, a second rotating shaft 222, and a first support arm 223. The first body portion 221 is sleeved outside the first diffuser blade 21 and includes an inner ring portion 2211, an outer ring portion 2212, and a second blade 2213. The outer ring portion 2212 is sleeved outside the inner ring portion 2211 and spaced apart from it. The second blade 2213 is disposed between the inner ring portion 2211 and the outer ring portion 2212 and connected to both. Multiple second blades 2213 are spaced apart along the circumferential direction of the first body portion 221. The second rotating shaft 222 is rotatable relative to the mounting frame 1. A second driving device 25 drives the second rotating shaft 222 to rotate. The first support arm 223 connects the second rotating shaft 222 and the inner ring portion 2211. Multiple first support arms 223 are spaced apart along the circumferential direction of the first body portion 221.

[0095] Therefore, the second rotating shaft 222 is driven to rotate by the second driving device 25, so that the second rotating shaft 222 rotates and drives the first body part 221 to rotate through the first support arm 223, thereby realizing the rotation of the second diffuser blade 22. This causes the airflow to change direction and form a vortex under the action of multiple second blades 2213, so that the airflow in the direction of entering the second diffuser blade 22 is inconsistent with the airflow out of the second diffuser blade 22, thereby changing the airflow from direct blowing wind to vortex wind.

[0096] Meanwhile, the inner ring 2211 is fitted outside the first diffuser blade 21, and the second blade 2213 is located between the inner ring 2211 and the outer ring 2212 and connected to the inner ring 2211 and the outer ring 2212, so that the rotating first diffuser blade 21 and the rotating second diffuser blade 222's second blade 2213 can disperse the airflow and then recombine it to form a mixed diffused airflow, thereby achieving more complete airflow dispersion, so that the airflow can be more fully dispersed to all corners of the space, thereby expanding the range of airflow dispersion.

[0097] In addition, the second rotating shaft 222 and the inner ring 2211 are connected by multiple first support arms 223, so that the rotation of the second rotating shaft 222 can drive the first body part 221 to rotate, and the multiple first support arms 223 provide a certain support for both the first body part 221 and the second rotating shaft 222, thereby improving the overall reliability.

[0098] Furthermore, the second rotating shaft 222 is sleeved outside the first rotating shaft 211 and spaced apart from it. This arrangement ensures that the first air diffuser blade 21 and the second air diffuser blade 22 rotate coaxially, so that the airflow generated by the first air diffuser blade 21 and the second air diffuser blade 22 can be superimposed on each other, thereby enhancing the air diffusion effect and making the airflow more uniform during the diffusion process, thus improving the air diffusion efficiency.

[0099] In some embodiments of the present invention, such as Figure 6 , Figure 14 , Figure 16 and Figure 18 As shown, along the air outlet direction of the diffuser assembly 100, the second blade 2213 extends obliquely toward the circumferential direction of the first body portion 221. Therefore, as the airflow changes direction and forms a vortex as it passes through the second blade 2213, the oblique extension of the second blade 2213 toward the circumferential direction of the first body portion 221 helps guide the airflow more smoothly through the second blade 2213, reducing the formation of eddies and turbulence, thereby improving the diffuser efficiency.

[0100] In some embodiments of the present invention, such as Figure 6 , Figure 14 , Figure 16 and Figure 18 As shown, in a cross-section perpendicular to the axial direction of the first body portion 221, the second blade 2213 is an arc shape protruding towards the circumferential direction of the first body portion 221. Therefore, during the process of airflow changing direction and forming a vortex as it passes through the second blade 2213, the arc shape of the second blade 2213 protruding towards the circumferential direction of the first body portion 221 in the cross-section perpendicular to the axial direction of the first body portion 221 guides the airflow more smoothly, reducing turbulence and resistance at the blade edges, making airflow more efficient, and thus improving air dispersion efficiency.

[0101] In some embodiments of the present invention, such as Figures 4-8 and Figures 13-18 As shown, the air diffuser assembly 100 also includes a third air diffuser blade 23. The second air diffuser blade 22 is sleeved outside the third air diffuser blade 23, and the third air diffuser blade 23 is sleeved outside the first air diffuser blade 21. The second air diffuser blade 22 and / or the first air diffuser blade 21 can rotate relative to the third air diffuser blade 23.

[0102] Thus, this configuration allows the first and second diffuser blades 21 and 22 to decompose, cut, disperse, and split the airflow, which is then recombined within the area of ​​the third diffuser blade 23. The third diffuser blade 23 further guides the mixed airflow, enhancing its mixing and uniformity while altering its diffusion direction and range. This results in more thorough airflow dispersion, allowing the airflow to spread more fully to every corner of the space, further expanding the dispersion range, and improving the windless feeling index and windless feeling airflow volume.

[0103] In some embodiments of the present invention, such as Figure 18 As shown, the third diffuser blade 23 includes a second body portion 231 and a third blade 232. The second body portion 231 is sleeved outside the first diffuser blade 21, and the third blade 232 is disposed on the inner peripheral wall of the second body portion 231. The third blade 232 consists of multiple blades spaced apart along the circumferential direction of the second body portion 231.

[0104] Thus, the third air diffuser blade 23 is fixed on the mounting frame 1 by the second body part 231, and the airflow dispersed by the first air diffuser blade 21 and the second air diffuser blade 22 is further mixed by the multiple third blades 232 arranged at intervals along the circumferential direction of the second body part 231, thereby further enhancing the mixing and uniformity of the airflow.

[0105] Furthermore, the third diffuser blade 23 also includes a second support arm 233. One end of the second support arm 233 is sleeved outside the first rotating shaft 211 and spaced apart from the first rotating shaft 211, and the other end is connected to the second body part 231. Thus, the second support arm 233 supports the first rotating shaft 211, thereby ensuring the reliability of the rotation of the first diffuser blade 21.

[0106] In some embodiments of the present invention, such as Figure 6 , Figure 14 , Figure 16 and Figure 18 As shown, along the air outlet direction of the diffuser assembly 100, the inner diameter of the second body portion 231 gradually increases, and the third blade 232 extends spirally along the inner peripheral wall of the second body portion 231. This arrangement guides the airflow, dispersed and mixed by the first diffuser blade 21 and the second diffuser blade 22, to flow out along the inclined direction of the third blade 232, reducing the formation of eddies and turbulence, thereby improving diffuser efficiency.

[0107] In some embodiments of the present invention, such as Figures 3-8As shown, the mounting frame 1 has a mounting groove 11, and the blade assembly 2 is located within the mounting groove 11. The bottom wall of the mounting groove 11 has ventilation holes 12. It can be understood that the bottom wall of the mounting groove 11 serves as the air inlet, and the airflow enters the mounting groove 11 through the ventilation holes 12, is dispersed by the blade assembly 2, and then flows out from the open end of the mounting groove 11. Simultaneously, the location of the blade assembly 2 within the mounting groove 11 provides a certain degree of protection for the blade assembly 2.

[0108] Furthermore, the ventilation holes 12 are arranged in multiple rows and columns along the length and width of the bottom wall of the mounting groove 11. Thus, the airflow passing through the mounting frame 1 can be dispersed and refined through the multiple ventilation holes 12, transforming the airflow into a finer airflow. The airflow passing through the mounting frame 1 can also be more uniform, delicate, and gentle, further improving the airflow dispersion effect of the air dispersion assembly 100. It should be noted that the cross-sectional shape of the ventilation holes 12 can be circular, triangular, square, or honeycomb, etc., and the specific shape is not limited here.

[0109] In some embodiments of the present invention, such as Figures 1-8 As shown, the air diffuser assembly 100 also includes an air outlet panel 3. The air outlet panel 3 covers the open opening of the mounting groove 11 and is connected to the mounting frame 1. The air outlet panel 3 has multiple spaced-apart first air outlet holes 31. Thus, airflow enters the mounting groove 11 through the ventilation holes 12, is diffused by the blade assembly 2, and then flows out through the multiple first air outlet holes 31 of the air outlet panel 3. Simultaneously, by covering the open opening of the mounting groove 11 with the air outlet panel 3, the air outlet panel 3 and the mounting frame 1 form a receiving space, effectively protecting the blade assembly 2 located within the receiving space and improving overall reliability.

[0110] In some embodiments of the present invention, such as Figure 1 As shown, multiple first air outlets 31 are arranged in multiple rows and columns along the length and width of the air outlet panel 3. Therefore, the airflow passing through the air outlet panel 3 can be further dispersed and refined through the multiple first air outlets 31, transforming the airflow into a finer airflow. This results in a more uniform, delicate, and gentle airflow from the air diffuser assembly 100, further improving the air diffuser effect of the air diffuser assembly 100. It should be noted that the cross-sectional shape of the first air outlet 31 can be circular, triangular, square, or honeycomb, etc., and the specific shape is not limited here.

[0111] The air conditioner 1000 according to an embodiment of the present invention is described below.

[0112] An air conditioner 1000 according to an embodiment of the present invention, such as Figures 1-18 As shown, it includes a housing 200 and a diffuser assembly 100. The housing 200 has an air outlet 201, and the mounting frame 1 is located at the air outlet 201 and connected to the housing 200.

[0113] Understandably, the housing 200 forms the overall appearance of the air conditioner 1000. An air duct 202 is formed inside the housing 200, and an air inlet is provided on the housing 200. The location of the air inlet is not limited, as long as it connects to the air duct 202. The housing 200 also houses a heat exchanger assembly 600 and a fan 700. The heat exchanger assembly 600 exchanges heat with the airflow passing over its surface, and the fan 700 drives the airflow from the air inlet to the air outlet 201. During the actual operation of the air conditioner 1000, outside air enters the housing 200 through the air inlet, undergoes heat exchange with the heat exchanger assembly 600, and then, under the action of the fan 700, flows through the air duct 202 to the air outlet 201 and exits the air conditioner 100 via the air diffuser assembly 100.

[0114] The mounting frame 1 is connected to the housing 200, thereby fixing the air diffuser assembly 100 to the housing 200. The mounting frame 1 extends along the length of the air outlet 201 (e.g., ...). Figure 3 Extending in the x-direction shown, multiple blade assemblies 2 are arranged at intervals along the length of the air outlet 201. Thus, the airflow from the duct 202 to the air outlet 201 flows through the multiple blade assemblies 2 and through the blade assemblies 2, which include a first diffuser blade 21 and a second diffuser blade 22. At least one of the first diffuser blade 21 and the second diffuser blade 22 is rotatably mounted on the mounting frame 1. The second diffuser blade 22 is fitted outside the first diffuser blade 21 and rotates relative to it, thereby improving the turbulence state during the airflow process. At the same time, it can reduce the airflow velocity and improve the smoothness of the airflow, so that the airflow blown out from the diffuser assembly 100 will not blow directly to the user, which can improve the comfort of the airflow and thus achieve the effect of a gentle breeze or no breeze in the air conditioner 1000.

[0115] According to an embodiment of the present invention, an air conditioner 1000 is provided with a diffuser assembly 100. The housing 200 has an air outlet 201. The mounting frame 1 is located at the air outlet 201 and connected to the housing 200. The blade assembly 2 includes a first diffuser blade 21 and a second diffuser blade 22. At least one of the first diffuser blade 21 and the second diffuser blade 22 is rotatably mounted on the mounting frame 1. The second diffuser blade 22 is sleeved outside the first diffuser blade 21 and rotates relative to it. This improves the turbulence state during the airflow process, reduces the airflow velocity, and improves the smoothness of the airflow. This prevents the airflow blown from the diffuser assembly 100 from blowing directly onto the user, thereby improving the comfort of the airflow and achieving a breeze or no breeze effect in the air conditioner 1000.

[0116] In some embodiments of the present invention, such as Figures 1-13 As shown, the mounting frame 1 has multiple spaced ventilation holes 12, and the air diffuser assembly 100 and the air outlet 201 are in the width direction (e.g., Figure 7An air outlet 2011 is formed by a spacer on at least one side (in the y-direction shown). The air conditioner 1000 also includes a switch door 300. The switch door 300 is movably disposed on the housing 200 along the width direction of the air outlet 201 and is used to open or close the air outlet 2011. When the switch door 300 opens the air outlet 2011, the switch door 300 blocks at least part of the ventilation hole 12.

[0117] Thus, this design enables the air conditioner 1000 to operate in multiple air supply modes, meeting diverse user needs. Furthermore, the door 300 not only blocks the air outlet 2011 but also the ventilation hole 12, achieving a dual-purpose design, resulting in higher structural space utilization and lower costs.

[0118] Specifically, when the door 300 opens the air outlet 2011, the door 300 blocks all the ventilation holes 12. Thus, the airflow to the air outlet 201 flows out of the air conditioner 1000 through the air outlet 2011, achieving the first air supply mode; or, when the door 300 opens the air outlet 2011, the door 300 blocks part of the ventilation holes 12, and the airflow to the air outlet 201 flows out of the air conditioner 1000 through the air outlet 2011 and the diffuser assembly 100, achieving the second air supply mode; or, when the door 300 closes the air outlet 2011, the airflow to the air outlet 201 flows out of the air conditioner 1000 through the ventilation holes 12 and the blade assembly 2, achieving the third air supply mode.

[0119] In some embodiments, such as Figures 9-11 As shown, the air diffuser assembly 100 and the air outlet 201 are spaced apart on both sides in the width direction to form two air outlets 2011. There are two opening and closing doors 300 corresponding to the air outlets 2011. The two opening and closing doors 300 move towards each other and away from each other to open or close the air outlets 2011.

[0120] Therefore, as Figure 9 As shown, when the door 300 opens the air outlet 2011, the door 300 blocks all ventilation holes 12, and the airflow to the air outlet 201 flows out of the air conditioner 1000 through the two air outlets 2011, achieving dual-flow airflow; or, as Figure 10 As shown, when the door 300 opens the air outlet 2011, the door 300 partially blocks the ventilation hole 12. The airflow to the air outlet 201 flows out of the air conditioner 1000 through the two air outlets 2011 and the air diffuser assembly 100, achieving three-flow air outlet; or, as Figure 11 As shown, when the door 300 closes the air outlet 2011, the airflow to the air outlet 201 flows out of the air conditioner 1000 through the air diffuser assembly 100, realizing a windless mode.

[0121] In some embodiments of the present invention, such as Figure 12 As shown, the door 300 has multiple spaced-apart second air outlets 301. This arrangement allows the multiple second air outlets 301 to further disperse and refine the airflow passing through the door 300, transforming the airflow into a finer stream. This results in a more uniform, delicate, and gentle airflow, further achieving the draftless effect of the air conditioner 1000. It should be noted that the cross-sectional shape of the second air outlets 301 can be circular, triangular, square, or honeycomb, etc., and the specific shape is not limited here.

[0122] In some embodiments of the present invention, such as Figures 7-12 As shown, the air conditioner 1000 also includes an air guide plate 400. The air guide plate 400 extends along the length of the air outlet 201 and is rotatably disposed at the air supply outlet 2011 to guide air in the width direction of the air outlet 201. When the door 300 closes the air supply outlet 2011, the air guide plate 400 is located upstream of the door 300.

[0123] Therefore, when the door 300 opens the air outlet 2011, the air guide plate 400 is rotatably positioned at the air outlet 2011 to guide the airflow in the width direction of the air outlet 201, meeting the user's air supply needs. Simultaneously, when the door 300 closes the air outlet 2011, the air guide plate 400 is rotatably positioned at the air outlet 2011 to avoid obstructing the door 300, resulting in higher structural space utilization and a smaller volume of the air conditioner 1000.

[0124] Furthermore, the air guide plates 400 are multiple ones spaced apart along the width direction of the air outlet 201. The multiple air guide plates 400 are rotatably disposed at the air outlet 2011. Thus, by such a configuration, in conjunction with the opening and closing door 300 moving along the direction of the air outlet 201, it can be achieved that when the opening and closing door 300 partially opens the air outlet 2011, the air guide plates 400 located at the opened air outlet 2011 can still guide air in the width direction of the air outlet 201.

[0125] In some embodiments of the present invention, such as Figures 6-8 As shown, the air conditioner 1000 also includes a louver assembly 500. The louver assembly 500 is located at the air outlet 201 and is situated upstream of the air diffuser assembly 100 along the airflow direction, serving to guide airflow along the length of the air outlet 201.

[0126] Therefore, the airflow from the air diffuser assembly 100 to the air conditioner 1000 is first guided by the louver assembly 500 along the length of the air outlet 201, then flows to the air diffuser assembly 100 and is dispersed by the blade assembly 2 before flowing out of the air conditioner 1000, thereby further improving the air dispersion effect of the air diffuser assembly 100 and the air supply range of the air conditioner 1000, and meeting the various needs of the air conditioner 1000.

[0127] Other configurations and operations of the air conditioner 1000 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
