Description

Technical Field

[0001] This invention belongs to the field of air conditioning technology, specifically relating to an air duct structure that provides uniform airflow. Background Technology

[0002] Existing air conditioners typically have air deflectors and louvers installed at the air outlet to adjust the direction of airflow, allowing cold and hot air to diffuse fully in the indoor environment and improve the temperature control efficiency of the air conditioner.

[0003] However, under long-distance air supply conditions, due to the long length of the air outlet, the distance between the air outlet and the air inlet of the air supply duct is different, and the air outlet speed is also different. This results in the inability to achieve a good temperature control effect in the indoor environment.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a duct structure with uniform airflow.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is: a duct structure with uniform airflow, comprising:

[0007] An air supply duct, wherein the air supply duct is provided with a mesh sleeve that communicates with the air inlet, and the mesh sleeve has a first sidewall facing the air outlet end of the air supply duct.

[0008] The first sidewall is provided with multiple air outlet nozzles on the side facing the air outlet;

[0009] The plurality of air outlet nozzles are used to blow air out in a fan-shaped pattern from one side of the air outlet of the air supply duct.

[0010] With the above solution, the first sidewall of the mesh is provided with multiple air outlet nozzles, so that the airflow blown out through the multiple air outlet nozzles is in a fan-shaped expansion state, ensuring uniform temperature change in the indoor environment, while reducing the airflow directly blowing towards the user, thereby improving the user experience.

[0011] Furthermore, the first sidewall is made of a flexible material and is inclined toward the air outlet inside the air supply duct.

[0012] With the above solution, as the airflow flows through the mesh, the first sidewall is supported by the airflow and forms a fan-shaped structure, which makes the airflow blown out by the multiple air outlet nozzles form a fan-shaped diffusion flow, ensuring a uniform airflow effect on the indoor environment.

[0013] Furthermore, the plurality of air outlet nozzles have the same inner diameter along the airflow direction;

[0014] The inner diameter of the plurality of air outlet nozzles gradually decreases in the direction perpendicular to the airflow direction, with the central axis of the first sidewall as the center, away from the central axis.

[0015] With the above solution, since the air pressure at the center is higher than that at the edge during the airflow process, in order to keep the air speed at multiple air outlet nozzles as consistent as possible, the inner diameter of the air outlet nozzles far from the central axis of the first side wall is set to gradually decrease to achieve a pressurization effect on the airflow, so that the airflow speed blown out by the air outlet nozzles at each position remains balanced, thereby ensuring the uniformity of airflow in the indoor environment.

[0016] Furthermore, the inner diameter of the plurality of air outlet nozzles gradually decreases in the direction of the air outlet of the air supply duct.

[0017] With the above scheme, the inner diameters of the multiple air outlet nozzles are different, so as to maintain a balanced airflow velocity. Furthermore, the multiple air outlet nozzles are designed as variable diameter structures with gradually decreasing inner diameters to increase the airflow velocity. Even in a large indoor environment, good air supply effect can still be achieved.

[0018] Furthermore, the mesh includes a second sidewall and a third sidewall for fixing the first sidewall;

[0019] The first sidewall is fixedly disposed on the second sidewall and the third sidewall;

[0020] The second and third sidewalls are detachably provided on the inner wall of the air supply duct.

[0021] With the above solution, the second sidewall and the third sidewall are used to fix the first sidewall, and the second sidewall and the third sidewall are provided on the inner wall of the air supply duct through the fixing component, so as to realize the detachable connection structure between the sleeve and the air supply duct.

[0022] Furthermore, the inner diameter of the mesh gradually decreases along the airflow direction.

[0023] The above scheme designs the mesh as a variable diameter structure with a gradually decreasing inner diameter, so that when the length of the air supply duct is long, the airflow flowing into the mesh will be pressurized, and the air outlet velocity at the beginning and end of the airflow direction will be kept relatively balanced, thus ensuring the uniformity of the air outlet of the air supply duct.

[0024] Furthermore, the air supply duct has a first air outlet arranged in a horizontal direction and a second air outlet arranged in a downward direction;

[0025] Alternatively, the air supply duct has a fan-shaped end face, and the fan-shaped end face is provided with an air outlet.

[0026] Furthermore, the air supply duct includes multiple air supply modules, each of which is equipped with the mesh, and the meshes are interconnected.

[0027] Furthermore, the adjacent meshes are interconnected via connecting components.

[0028] Furthermore, an air outlet is provided at the connection end between the mesh and the other mesh;

[0029] A guide grille is provided at the air outlet location.

[0030] With the above solution, a guide grille is provided at the air outlet position, so that the airflow can maintain a relatively balanced flow state as it flows through multiple sleeves in sequence, avoiding airflow turbulence and loss of air volume during the flow of air in the sleeve of the air supply duct.

[0031] Furthermore, both the first and second air outlets of the air supply duct are provided with guide plates, and the guide plates are used to close the first air outlet and / or the second air outlet.

[0032] With the above solution, in addition to providing multiple air outlet nozzles on the first side wall of the mesh, a guide plate is also provided at the first or second air outlet position, which can further improve the airflow stability of the air supply duct; and the guide plate can also be used to close the first or second air outlet, so that the user can selectively open or close the first or second air outlet according to specific usage needs.

[0033] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0034] A mesh is installed inside the air supply duct, which is connected to the air inlet of the air supply duct. The first side wall of the mesh is equipped with multiple air outlet nozzles, the outlets of which are arranged in a fan shape. This makes the airflow blown out of the air outlet of the air supply duct fan-shaped, ensuring uniform temperature change in the indoor environment, while reducing the airflow directly blowing on the user, thereby improving the user experience.

[0035] The air outlet nozzles are designed with a smaller inner diameter in the direction away from the central axis of the first side wall, thereby increasing the airflow speed in the direction away from the central axis of the first side wall and relatively slowing down the airflow speed in the direction of the central axis of the first side wall. This achieves a relatively uniform airflow speed at the air outlet and avoids creating temperature differences between different locations in the indoor environment.

[0036] The end face of the air supply duct with the air outlet can be a fan-shaped end face. Correspondingly, the first side wall of the mesh is a curved surface structure corresponding to the fan-shaped end face of the air supply duct. Multiple air outlet nozzles are evenly distributed on the first side wall to form a fan-shaped distribution structure. Since the structure of the air outlet is also a fan-shaped end face, it can ensure that the airflow at the air outlet forms a stable expansion effect, ensuring that the temperature changes at different locations in the indoor environment remain relatively consistent.

The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0051] 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.

[0052] like Figures 1 to 8 As shown, the present invention provides a uniform airflow duct structure, comprising:

[0053] Air supply duct 1, the air supply duct 1 is provided with a mesh 2 that is connected to the air inlet 101, the mesh 2 has a first side wall 201 facing the air outlet end of the air supply duct 1.

[0054] The first sidewall 201 has a curved structure, and multiple air outlet nozzles 204 may be provided on the first sidewall 201.

[0055] Figure 1 This is a schematic diagram of the structure of the air supply duct 1 in the embodiment of this application; Figure 2 for Figure 1 A schematic diagram of the structure of the central air supply module 100; Figure 3 for Figure 2 A schematic diagram of the mesh 2 structure inside the central air supply module 100. (Reference) Figure 1 , Figure 2 and Figure 3 The first sidewall 201 can be a curved structure that protrudes toward the first air outlet 102 and the second air outlet 103, and multiple air outlet nozzles 204 can be evenly distributed on the first sidewall 201. The multiple air outlet nozzles 204 form a fan-shaped distribution along the curved surface of the first sidewall 201, so that the airflow passes through the multiple air outlet nozzles 204 and then passes through the first air outlet 102 and the second air outlet 103 to form a uniformly distributed airflow supply state.

[0056] In existing technologies, air conditioner outlets typically have a deflector 104 to adjust the direction of the airflow. However, existing deflectors 104 can only achieve uniform directional adjustment, resulting in insufficient airflow diffusion within the indoor environment. This leads to uneven indoor temperature variations or direct airflow onto users, significantly reducing the user experience. To address these issues, a mesh cover 2 is installed inside the air supply duct. The mesh cover 2 is connected to the air inlet 101 of the air supply duct 1, and the first sidewall 201 of the mesh cover 2 has multiple air outlet nozzles 204. The nozzles 204 are arranged in a fan-shaped distribution, causing the airflow from the air outlet of the air supply duct 1 to diffuse in a fan shape. This ensures uniform temperature changes within the indoor environment while reducing direct airflow onto users, thereby improving the user experience.

[0057] Optionally, the multiple air outlet nozzles 204 have the same inner diameter along the airflow direction; and the inner diameter gradually decreases along the direction perpendicular to the airflow direction, with the central axis of the first sidewall 201 as the center, away from the central axis of the first sidewall 201.

[0058] Figure 3 This is a schematic diagram of the structure of the mesh 2 in this application. (Reference) Figure 2 and Figure 3 Based on the analysis of airflow state, the airflow is largest at the central axis of the first sidewall 201. When the first sidewall 201 is a fan-shaped end face, the airflow is smaller away from the central axis. Therefore, the inventors designed the inner diameter of the air outlet nozzle 204 to be smaller in the direction away from the central axis of the first sidewall 201, thereby increasing the airflow speed away from the central axis of the first sidewall 201 and relatively slowing down the airflow speed at the central axis of the first sidewall 201. This achieves a relatively uniform overall airflow speed at the air outlet and avoids temperature differences between different locations in the indoor environment.

[0059] In order to increase the airflow velocity from the air supply duct 1 and ensure the long-distance air supply purpose of the air supply duct 1, the air outlet nozzle 204 is designed as a tapered structure with a gradually decreasing inner diameter, thereby increasing the airflow velocity at the air outlet of the air supply duct 1.

[0060] Figure 5 This is a side view of the air inlet 101 of the air supply duct 1 in this embodiment of the application. (See reference) Figure 5 In the embodiments of this application, the netting 2 includes a second sidewall 202 and a third sidewall 203 for fixing the first sidewall 201. The first sidewall 201 is fixedly disposed at both ends perpendicular to the airflow direction at the ends of the second sidewall 202 and the third sidewall 203. The second sidewall 202 and the third sidewall 203 are connected to each other, so that the cross-sectional projection of the netting 2 is a triangular structure. Furthermore, the first sidewall 201 can be made of a flexible material, so that the cross-sectional projection of the netting 2 is a fan-shaped structure, and multiple air outlet nozzles 204 are evenly distributed on the first sidewall 201 to realize the fan-shaped distribution structure of the multiple air outlet nozzles 204.

[0061] Optionally, the end face of the air supply duct 1 with the air outlet can be a fan-shaped end face. Correspondingly, the first side wall 201 of the mesh 2 is a curved surface structure corresponding to the fan-shaped end face of the air supply duct 1. Multiple air outlet nozzles 204 are evenly distributed on the first side wall 201 to form a fan-shaped distribution structure. Since the structure of the air outlet is also a fan-shaped end face, it can ensure that the airflow at the air outlet forms a stable expansion effect, and ensure that the temperature changes at different locations in the indoor environment remain relatively consistent.

[0062] Figure 6 This is a schematic diagram of another embodiment of the air supply duct 1 in this application. (Reference) Figure 6 In another embodiment, the air supply duct 1 may have a first air outlet 102 arranged in the horizontal direction and a second air outlet 103 arranged downward; in this case, the first side wall 201 of the mesh 2 may also adopt a curved structure to achieve uniform air outlet at the positions of the first air outlet 102 and the second air outlet 103.

[0063] Furthermore, guide vanes 104 can be evenly distributed on the first air outlet 102 and the second air outlet 103 to form secondary guides for the airflow blown out by the multiple air outlet nozzles 204, thereby further improving the uniformity of the airflow.

[0064] Preferably, the first partition can be made of a flexible material, which can expand the first partition during the flow of air through the mesh 2, so that the multiple air outlet nozzles 204 on the first partition are arranged in a fan-shaped distribution structure; preferably, the first partition is a trapezoidal structure when unfolded, so that the mesh 2 can be a variable diameter structure with the inner diameter gradually decreasing along the airflow direction, thereby ensuring the air outlet effect of the multiple air outlet nozzles 204.

[0065] Optionally, the second sidewall 202 and the third sidewall 203 are detachably mounted on the inner wall of the air supply duct 1 without an air outlet via a fixing assembly. The fixing assembly can be a positioning element and a positioning groove on the second sidewall 202, the third sidewall 203 and the inner wall of the air supply duct 1, respectively, to ensure that the sleeve 2 can be stably mounted on the air supply duct 1 while also facilitating disassembly. The specific structure of the fixing assembly can also be Velcro, spring clips, injection-molded hooks, magnetic connections (flexible magnetic strips and iron sheets), etc. The specific structure of the fixing assembly is not specifically limited in this application.

[0066] Optional, Figure 7 This is a schematic diagram illustrating another embodiment of the air supply duct in this application. (Reference) Figure 7 The air supply module 100 has two first air outlets 102 arranged in opposite directions along the horizontal direction and a second air outlet 103 arranged downwards; the corresponding second sidewall 202 and third sidewall 203 are integrally formed and form a horizontal end face, and a first sidewall 201 may be provided at the lower end of the horizontal end face formed by the second sidewall 202 and the third sidewall 203. The other parts of this solution are the same as those in the above embodiment, so they will not be described in detail here.

[0067] refer to Figure 1 and Figure 2 Furthermore, the inner diameter of the mesh 2 gradually decreases along the airflow direction. When the above-mentioned air supply duct 1 is applied to a larger indoor environment, since the air supply duct 1 is formed by connecting multiple air supply modules 100 to form a longer air supply duct 1, the two ends of the mesh 2 can be provided with connecting components 3 for connecting adjacent meshes 2 to each other.

[0068] Specifically, Figure 8 This is a schematic diagram of the connection structure between adjacent first sidewalls 201 of the sleeve in an embodiment of this application. (Reference) Figure 8 The connecting component 3 includes a snap-fit ​​element 301 located at one end of the mesh 2 along the airflow direction and a snap-fit ​​groove 302 located at the other end. Adjacent meshes 2 are connected to each other via the snap-fit ​​element 301 and the snap-fit ​​groove 302, respectively. The specific structure of the connecting component 3 is not specifically limited in the embodiments of this application.

[0069] Optional, Figure 4 This is a side view of the air outlet 205 side of the mesh 2 in this embodiment of the application. (Refer to...) Figure 4 An air outlet 205 is provided at the connection end between the first set of netting 2 and the second set of netting 2, and a guide grille 206 is provided at the air outlet 205. Specifically, the guide grille can be multiple grille bars with a grid-like distribution structure, and each grille bar is an individually detachable connection structure. Users can judge whether there is air volume loss during the airflow process based on the air outlet effect and the air volume, and selectively remove some grille bars according to the air outlet effect. This can realize that the grille bars form a parallel flow uniform structure, further reducing air volume loss.

[0070] In the embodiments of this application, a detachable sleeve 2 is provided in the air supply duct 1, and multiple air outlet nozzles 204 are provided on the first side wall 201 of the sleeve 2. The cross-sectional projection of the multiple air outlet nozzles 204 in the air supply duct 1 is a fan-shaped distribution structure. During the air outlet process, the airflow can be fully expanded, so that the temperature change at different locations in the indoor environment is relatively consistent. The sleeve 2 is detachably provided in the air supply duct 1, and the user can replace the sleeve 2 at any time according to the usage situation, so as to quickly clean the air supply duct 1. Furthermore, the sleeve 2 is set as a fan-shaped structure in cross-sectional projection. The first side wall 201 is made of flexible material, so that the multiple air outlet nozzles 204 on the first side wall 201 form a fan-shaped distribution. With the central axis of the first side wall 201 as the center, the inner diameter of the air outlet nozzles 204 gradually decreases in the direction away from the central axis, so that the airflow speed blown by each air outlet nozzle 204 is kept balanced, so that the temperature change at different locations in the indoor environment is as consistent as possible, and the amount of air blown directly to the user is reduced, thereby improving the user experience.

[0071] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced.
