Furthermore, the airflow passing through the second air dispersion plate is diffused by the impeller of the air dispersion module. This diffused airflow has a lower velocity and is not concentrated directly onto the first air dispersion plate. Consequently, it is less likely to collide with the first air dispersion plate and generate noise, thus helping to reduce noise in wind-free mode. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0053] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative positional relationship and movement of various components under a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0054] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0055] The present invention provides an embodiment of an air dispersing device that improves the wind-free air dispersing effect, thereby enhancing the comfort of the air dispersing device. The air dispersing device can be used on an air outlet device to disperse airflow. The air outlet device can be an air outlet device such as an air conditioner or an air purifier. To avoid redundancy, the following embodiments will primarily be described using the air dispersing device in a floor-standing air conditioner as a reference.

[0056] See also Figures 9 to 11 In one embodiment of the air dispersing device of the present invention, the air dispersing device includes an air dispersing frame 100 and an air dispersing module 200. The air dispersing frame 100 includes a first air dispersing plate 110 and a second air dispersing plate 120, with an air passage cavity 130 formed between the first air dispersing plate 110 and the second air dispersing plate 120. The first air dispersing plate 110 is provided with air dispersing holes, and the second air dispersing plate 120 is provided with a vent 130. The air dispersing module 200 includes a rotor 210 rotatably disposed within the air passage cavity 130 for diffusing air.

[0057] See also Figures 11 to 13 The air dispersion frame 100 is adapted to be rotatably mounted on an air conditioner. When the air dispersion frame 100 is rotated, the air dispersion frame 100 can be switched to dissipate air from the first air dispersion plate 110 or from the second air dispersion plate 120, thereby achieving different windless air supply modes. The first air dispersion plate 110 and the second air dispersion plate 120 can be integrally manufactured or separately manufactured and then assembled together. To reduce the molding difficulty and facilitate manufacturing, the first air dispersion plate 110 and the second air dispersion plate 120 of the air dispersion frame 100 are separately manufactured and then detachably assembled into a single unit.

[0058] The first air dispersion plate 110 is provided with a plurality of air dispersion holes, which are dispersedly arranged on the surface of the first air dispersion plate 110. After passing through the first air dispersion plate 110, the airflow is broken up into strands of fine airflow, thereby reducing the airflow speed and softening the wind sensation. It should be noted that the air dispersion holes of the first air dispersion plate 110 are micropores with a relatively small aperture. The diameter of the air dispersion holes can be designed to be 2mm to 5mm. In this case, the air dispersed through the first air dispersion plate 110 feels relatively comfortable, achieving comfortable and windless air supply. For another example, the diameter of the air dispersion holes of the first air dispersion plate 110 is designed to be 5mm to 10mm. In this case, the air dispersed through the first air dispersion plate 110 feels relatively soft, achieving a soft and windless air supply.

[0059] The second air dispersion plate 120 is provided with a plurality of vents 130 spaced apart along the length of the second air dispersion plate 120. It should be noted that the vents 130 are openings with a diameter larger than the air dispersion holes. These vents 130 can be circular, oval, or square, without limitation. Specifically, the vents 130 are circular. The number of vents 130 is not limited and can be 2 to 10, depending on the size of the air conditioner. Furthermore, the second air dispersion plate 120 can be provided with air dispersion holes dispersedly arranged around the vents 121. This allows airflow to not only pass through the vents of the second air dispersion plate 120 but also escape through the air dispersion holes on the second air dispersion plate 120.

[0060] The impeller 210 of the air dispersing module 200 is rotatably disposed within the air passage 130 between the first and second air dispersing plates 110 and 120. The impeller 210's rotation axis extends from the first and second air dispersing plates 110 and 120. When air flows through the impeller 210, it spins and disperses the airflow, causing it to spread outward around the impeller, effectively expanding the air supply range and reducing wind speed, thereby effectively reducing the sense of wind and achieving a sound-free, wind-free effect.

[0061] Regarding the assembly structure of the impeller 210, the impeller 210 can be rotatably connected to the first air dispersion plate 110 or the second air dispersion plate 120, or a mounting bracket can be disposed within the air passage 130 between the first air dispersion plate 110 and the second air dispersion plate 120, and the impeller 210 can be rotatably connected to the mounting bracket. Optionally, the impeller 210 can be rotatably connected to the second air dispersion plate 120. The impeller 210 can be directly connected to the second air dispersion plate 120, or a support structure for rotatably connecting the impeller 210 can be constructed on the second air dispersion plate 120. The support structure can be a grid frame, a cross bracket, or a stationary impeller 220 (described in detail later).

[0062] The technical solution of the present invention is to configure an air dispersion module 200 on an air dispersion frame 100 of an air dispersion device, wherein the air dispersion frame 100 includes a first air dispersion plate 110 and a second air dispersion plate 120 with an air passage cavity 130 formed therebetween, the first air dispersion plate 110 is provided with air dispersion holes, and the second air dispersion plate 120 is provided with a vent; the impeller 210 of the air dispersion module 200 is rotatably configured in the air passage cavity 130, and the impeller 210 is arranged opposite to the vent 130, so that when the air dispersion device is working, the impeller 210 rotates to diffuse the airflow, which can not only disperse the airflow to reduce the wind speed, but also increase the airflow diffusion range.

[0063] Compared to conventional air dispersion through a single layer of air dispersion plates, the air dispersion device of the present invention, through the air dispersion frame 100 and the air dispersion module 200, can disperse and diffuse the airflow at least twice, thereby effectively reducing wind speed, expanding the air supply range, improving the windless air dispersion effect, and thus enhancing the comfort of the air dispersion device. In addition, the airflow blowing through the second air dispersion plate 120 is rotated and diffused by the impeller 210 of the air dispersion module 200. The airflow speed after diffusion is reduced, and it will not directly impact the first air dispersion plate 110. Therefore, it is less likely to collide with the first air dispersion plate 110 and generate noise, which helps to reduce noise in the windless mode.

[0064] See also Figure 14 、 Figure 16 and Figure 17 Based on the above embodiment, the impeller 210 includes a hub 211 and a plurality of impeller blades 212 spaced circumferentially around the hub 211. The plurality of impeller blades 212 are curved in the same circumferential direction so that after the airflow passes through the impeller 210, the impeller blades 212 of the passive impeller 210 guide the airflow, causing it to spiral in the same direction and propel the air forward, thereby enhancing the forward air diffusion effect of the air dispersion module. The hub 211 of the impeller 210 is rotatably mounted on the vent 130. As previously mentioned, a support structure for the rotatable connection of the impeller 210 can be provided at the vent 130. This support structure can be a support frame such as a grid frame or a cross bracket, or it can be a stationary impeller 220 (described in detail later).

[0065] See also Figures 15 to 17 In one embodiment, the air dispersing module 200 further includes a stationary impeller 220 disposed opposite to the moving impeller 210. The stationary impeller 220 is disposed at the vent 130. The stationary impeller 220 is integrally formed with the second air dispersing plate 120 or is separately formed and then connected to form a whole (the manner in which the stationary impeller 220 is assembled into a whole with the second air dispersing plate 120 can be seen in FIG. Figures 21 to 25 That is, the stationary impeller 220 and the second air dispersing plate 120 may be integrally formed, or may be manufactured separately and then assembled together.

[0066] Specifically, the impeller 220 includes a hub 221 and a plurality of stator blades 222 spaced circumferentially around the hub 221. The blades 222 are curved and arranged in the same circumferential direction. The ends of the blades 222 are fixedly connected to the peripheral wall of the vent 130, allowing the impeller 220 and the second air dispersing plate 120 to be assembled and disassembled as a whole.

[0067] Furthermore, the multiple moving blades 212 of the moving impeller 210 are all curved in the same circumferential direction; the multiple stationary blades 222 of the stationary impeller 220 are all curved in the same circumferential direction, and the curvature of the stationary blades 222 is consistent with the curvature of the moving blades 212. This ensures that the direction in which the airflow, after passing through the moving impeller 210, rotates and diffuses is consistent with the direction in which the airflow is guided by the stationary blades 222. As a result, the airflow is first guided by the stationary blades 222 and then acquires rotational diffusion potential energy. Driven by this potential energy, the airflow then smoothly enters the moving impeller 210. The moving blades of the stationary impeller 210 then successively rotate and diffuse in the same direction, giving the airflow not only the potential energy to propel it forward but also the potential energy to rotate and diffuse around it, thereby achieving the effect of blowing a large amount of air forward but with a weaker sense of wind.

[0068] In one embodiment, an air guide ring 122 is provided on the side of the second air dispersing plate 120 facing the first air dispersing plate 110. The air guide ring 122 protrudes from the periphery of the vent 121 toward the first air dispersing plate 110. The air guide ring 122 not only guides more air into the vent 121, thereby increasing the amount of air passing through the stator 220 and increasing the windless airflow, but also has a larger inner surface area for mounting the stator 220, thereby reducing the difficulty of installation.

[0069] Furthermore, the impeller 210 and the stationary impeller 220 are arranged opposite each other. When the windless mode is activated, airflow is first directed from the vent 130 of the second air dispersion plate 120 through the stationary impeller 220 into the air cavity 130. During this process, the airflow follows the twisting direction of the stationary blades 222 of the stationary impeller 220, being guided to spiral in the same direction and propel forward. This imparts rotational potential energy to the airflow before entering the impeller 210. Subsequently, as this airflow with rotational potential energy continues to flow into the impeller 210, the rotation of the impeller 210 strongly drives the airflow to further rotate and diffuse, effectively enhancing the effect of the airflow's rotational diffusion and greatly improving the comfort of the windless mode. The coordination between the stationary impeller 220 and the impeller 210 allows more airflow to pass through the air dispersion device, effectively increasing the airflow volume in the windless mode.

[0070] See also Figures 16 to 18Based on this, the hub 211 of the impeller 210 can be rotatably mounted to the hub 221 of the stationary impeller 220, eliminating the need for an additional mounting bracket for mounting the impeller 210. Optionally, the hub 211 of the impeller 210 is provided with a mounting portion 213, which is rotatably mounted on the hub 221 of the stationary impeller 220. The hub 221 of the stationary impeller 220 is provided with a mounting groove 223 for mounting the mounting portion 213 of the impeller 210. During assembly, the mounting portion 213 of the impeller 210 is rotatably mounted within the mounting groove 223 of the stationary impeller 220, allowing the impeller 210 to rotate around the mounting groove 223 of the stationary impeller 220 via the mounting portion 213.

[0071] As for the rotation driving method of the impeller 210, it can be driven by the airflow entering from the vent 130, or the impeller 210 can be configured with a driver 330 to drive the impeller 210 to rotate. Figures 13 to 15 In this embodiment, the air dispersion device further includes a louver assembly 300. The louver assembly 300 is disposed on a side of the second air dispersion plate 120 facing away from the first air dispersion plate 110. The louvers of the louver assembly 300 are interlocked with the impeller 210. In other words, the impeller 210 is driven to rotate by the louver assembly 300.

[0072] See also Figure 13 、 Figure 15 and Figure 19 In one embodiment, the louver assembly 300 includes a connecting rod 320 and a plurality of louvers 310 linked by the connecting rod 320. The louvers 310 are provided with a connecting shaft 311. The connecting shaft 311 passes through the vent 121 and is fixedly connected to the impeller 210, thereby linking the impeller 210 and the louvers 310. Because the impeller 220 is located at the vent 121, the connecting shaft 311 passes through the impeller 220 and is fixedly connected to the hub 211 of the impeller 210 to prevent interference between the impeller 220 and the impeller 210.

[0073] Specifically, multiple louvers 310 are spaced apart along the length of the air dispersion frame 100. A connecting rod 320 extends along the length of the air dispersion frame 100 in an elongated strip, connecting the multiple louvers 310 in sequence. Each impeller 210 corresponds to at least one of the louvers 310, and the impeller 210 is fixedly connected to its corresponding louver 310. When the connecting rod 320 moves up and down, it causes the louvers 310 to swing up and down, creating a swiveling wind. During this oscillation, the connecting shaft 311 of the louvers 310 rotates relative to the stationary impeller 220, causing the connecting shaft 311 to rotate synchronously with the impeller 210. This eliminates the need for a separate driver for the impeller 210, thereby reducing the number of drivers used in the air dispersion device and contributing to cost savings.

[0074] See also Figure 14 、 Figure 18 and Figure 19 In one embodiment, in order to facilitate the connection between the louver 310 and the impeller 210, optionally, the hub 211 of the impeller 210 is provided with a connecting hole 214 for connecting the connecting shaft 311; the connecting shaft 311 is provided with a separating groove 3112 opened along its axial direction, and the separating groove 3112 separates the connecting shaft 311 into two opposite elastic arms 3111, and the elastic arms 3111 are clamped and fixed to the inner wall of the connecting hole 214.

[0075] Specifically, the presence of the separation groove 3112 on the connecting shaft 311 allows the two elastic arms 3111 of the connecting shaft 311 to elastically deform radially, thereby achieving an optimal tensioning effect. When connecting the louver 310 and the impeller 210, the two elastic arms 3111 can be first pinched together, bringing them closer together and reducing the diameter of the connecting shaft 311. This reduces the resistance to the connecting shaft 311 entering the connecting hole 214 of the impeller 210, allowing the connecting shaft 311 to be accurately and smoothly inserted into the connecting hole 214. Once the connecting shaft 311 is properly inserted, the two elastic arms 3111 are released. The two elastic arms 3111 tend to expand outward, clinging to the inner wall of the connecting hole 214 and securing them there, making it difficult for the connecting shaft 311 to fall out of the connecting hole 214.

[0076] For the locking connection between the elastic arm 3111 and the connecting hole 214, mutually cooperating snap structures can be provided on the elastic arm 3111 and the connecting hole 214 to achieve locking engagement. In this embodiment, a hook 311a is optionally provided at the end of the elastic arm 3111; and a slot 214a is provided on the inner wall of the connecting hole 214, adapted to be engaged by the hook 311a.

[0077] During the aforementioned process of connecting the louver 310 and the impeller 210, when the hook 311a at the end of the connecting shaft 311 of the louver 210 reaches the slot 214a, the connecting shaft 311 is inserted into place. At this time, the two elastic arms 3111 are released, and the two elastic arms 3111 expand outward, locking the hooks 311a at their ends into the slot 214a. This makes it difficult for the connecting shaft 311 to overcome the restraining force of the slot 214a and fall out in the opposite direction. To remove the louver 310, the two elastic arms 3111 of the connecting shaft 311 are squeezed again, reducing the diameter of the connecting shaft 311. The hooks 311a of the two elastic arms 3111 separate from the sides of the slot 214a, allowing the elastic arms 3111 to be smoothly withdrawn from the connecting hole 214, and the louver 310 can be removed.

[0078] Furthermore, to enhance the secure connection between the louver 310 and the impeller 210, the inner wall of the connection hole 214 is further provided with a positioning portion 214b or a positioning groove 311b, and the circumferential side of the elastic arm 3111 is provided with the other of the positioning portion 214b or the positioning groove 311b, with the positioning portion 214b engaging with the positioning groove 311b. Specifically, the inner wall of the connection hole 214 is provided with a positioning portion 214b, and the inner wall of the connection hole 214 is provided with a positioning groove 311b. After the hook 311a of the elastic arm 3111 engages with the side of the groove 214a, the positioning protrusion 214b on the top surface of the boss fits neatly into the positioning groove 311b on the side of the elastic arm 3111, thereby achieving dual restriction of the axial movement of the connecting shaft 311 and significantly enhancing the secure connection between the louver 310 and the impeller 210.

[0079] In one embodiment, in order to facilitate the driving of the louver 310 to swing, the louver assembly 300 also includes a driver 330. The driver 330 is installed on the wind dispersion frame 100 and connected to the connecting rod 320. The driver 330 is used to drive the connecting rod 320 to move up and down, thereby driving the louver 310 to swing.

[0080] See also Figure 10 、 Figure 11 and Figure 13 Based on any of the above embodiments, the air dispersion frame 100 has a rotation axis extending along its length, and the air dispersion frame 100 is adapted to be rotatably mounted about the rotation axis on the air outlet 411 of the floor-standing air conditioner 400. Optionally, the rotation axis is positioned on the side of the second air dispersion plate facing away from the first air dispersion plate 110, thereby minimizing the distance between the air dispersion module 200 and the first air dispersion plate 110. This allows the airflow to be dispersed and dispersed by one of the air dispersion modules and quickly reach the other air dispersion module for further dispersion, effectively enhancing the windless effect.

[0081] In one embodiment, the first and second air dispersing plates 110, 120 can be flat or curved. Specifically, in this embodiment, the first and second air dispersing plates 112, 120 are arranged in an arc shape, convexly facing the same side. Taking the first air dispersing plate as an example, the curved surface of the first air dispersing plate 110 allows the first air dispersing plate 110 to obtain a larger air dispersing area, effectively increasing the air dispersing area of ​​the first air dispersing plate 110 and thereby expanding the air diffusion range of the first air dispersing plate 110. Of course, in other embodiments, the first air dispersing plate 110 is arranged in an arc shape, convexly facing the same side, while the second air dispersing plate 120 is arranged in a flat plate shape.

[0082] See also Figure 13In one embodiment, the longitudinal sides of the first air dispersing plate 110 are connected to the longitudinal sides of the second air dispersing plate 120, thereby forming an air passage cavity 130 between the first air dispersing plate 110 and the second air dispersing plate 120. In a cross-section of the air dispersing frame 100 taken along a plane perpendicular to its longitudinal direction, the air passage cavity 130 is crescent-shaped. Airflow can only enter through the air dispersing module 200, pass through the air passage cavity 130, and then be blown out of the first air dispersing plate 110.

[0083] Based on any of the above embodiments, both ends of the wind dispersion frame 100 are configured with a rotating shaft 101 extending along the length direction of the wind dispersion frame 100; the wind dispersion frame 100 is suitable for being rotatably mounted on the air conditioner via the rotating shaft 101, so that the wind dispersion frame 100 can be adjusted by rotating the wind dispersion frame 100.

[0084] See also Figure 1 and Figure 2 The present invention also provides a floor-standing air conditioner 400, comprising a housing 410 and an air dispersing device. Housing 410 is provided with an air outlet 411, which is provided with a damper 340. The air dispersing device is rotatably mounted to air outlet 411. The rotation axis of the air dispersing device extends along the length of air outlet 411. The specific structure of the air dispersing device is similar to that of the above-mentioned embodiments. Since this floor-standing air conditioner 400 utilizes all the technical solutions of all the above-mentioned embodiments, it also possesses all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, and therefore will not be further elaborated here.

[0085] See also Figure 1 and Figure 2 In one embodiment, the floor-standing air conditioner 400 further includes a heat exchanger 420 and a wind wheel 430; the heat exchanger 420 is arranged between the air inlet and the wind wheel 430, and surrounds the wind wheel 430 in a semi-enclosed shape. The number of wind wheels 430 can be one or two. Specifically, the number of wind wheels 430 is two, and the two wind wheels 430 are respectively used to supply air to the two air outlets 411. Each air outlet 411 of the air outlet duct 212 is equipped with a wind dissipation device. In one embodiment, the floor-standing air conditioner 400 has an off mode, a normal air supply mode, and a no-wind mode. Among them:

[0086] See also Figure 1 and Figure 2 In the shutdown mode, the air dispersing device rotates until the first air dispersing plate 110 is located at the innermost side of the air outlet 411. At this time, the first air dispersing plate 110 and the second air dispersing plate 120 of the air dispersing frame 100 of the air dispersing device are both retracted into the inner side of the air outlet 411, preventing the air dispersing frame 100 from interfering with the damper 340 closing the air outlet 411.

[0087] See also Figure 3 and Figure 4 In the conventional air supply mode, the air dispersing device rotates until the first and second air dispersing plates 110, 120 are located on opposite sides of the air outlet 411. At this point, the first and second air dispersing plates 110, 120 are retracted near the inner wall of the air outlet 411, occupying a relatively small cross-sectional area of ​​the air outlet duct 212 and less likely to block airflow, thus achieving conventional air supply.

[0088] See also Figure 5 and Figure 9 In the windless mode, the wind dispersing device rotates until the first wind dispersing plate 110 faces the outside of the air outlet 411. At this point, the first and second wind dispersing plates 110 and 120 are deployed across the ventilation cross-section of the air outlet duct 212. Airflow from the air outlet duct is sequentially intercepted by the second wind dispersing plate 120, the wind dispersing module 200, and the first wind dispersing plate 110, thereby achieving windless air delivery.

[0089] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made by using the contents of the present description and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
