[0041] The present invention provides an air outlet plate 200, which can be installed on an air outlet device to guide the air flow to blow out. The air outlet plate 200 has a relatively large air outlet surface area, which can effectively expand the air outlet range of the air outlet plate 200 and improve the comfort of the air outlet plate without wind feeling. As for the type of the air outlet device, the air outlet device can be an air conditioner, an air machine, an air purifier and other air outlet devices; among them, the air conditioner can be any one of a wall-mounted air conditioner indoor unit, a floor-standing air conditioner indoor unit, a mobile air conditioner, and a ceiling-mounted air conditioner. Hereinafter, the floor-standing air conditioner will be mainly taken as an example for introduction and explanation.

[0042] Please refer to Figures 1 to 3 , in an embodiment of the air outlet plate 200, the air outlet plate 200 includes a plate body 210 and a hole crown 220; wherein, the plate body 210 is provided with an air outlet hole 211 along its thickness direction; the hole crown 220 is arranged on the plate body 210 and covers the air outlet end of the air outlet hole 211, and a plurality of air diffusing holes 221 are formed in the hole crown 220, and the air diffusing holes 221 are communicated with the air outlet holes 211 of the plate body 210.

[0043] Specifically, the air outlet plate 200 can be a wind guiding plate arranged at the air outlet of the air outlet device, or any one of the bottom plate, the front panel, and the side panel of the housing of the air outlet device. The plate body 210 of the air outlet plate can be arranged in a long strip shape, or can be arranged in a circular shape, a square shape or other irregular shapes. Specifically here, the plate body 210 is arranged in a long strip shape, the plate body 210 has a windward surface and an air outlet surface, and the air outlet hole 211 of the plate body 210 penetrates from the windward surface of the plate body 210 to its air outlet surface.

[0044] For the hole crown 220, the hole crown 220 is arranged on the air outlet surface of the plate body 210 to cover the air outlet end of the air outlet hole 211 of the plate body 210. The hole crown 220 is arranged in a cap shape and covers the air outlet hole 211, so that the hole crown 220 has a 3D stereoscopic effect, and an inner cavity is formed inside the hole crown 220. The air outlet airflow first flows into the inner cavity of the hole crown 220 from the air outlet hole 211 of the air outlet plate 200, and then is dispersed and blown out through the plurality of air diffusing holes 221 in the inner cavity of the hole crown 220, forming strands of thin filament airflows and blowing outwards.

[0045] Since the hole crown 220 covers the air outlet hole 211 and the surface of the hole crown 220 relative to the air outlet plate 200 is a 3D three-dimensional structure, the surface area of each hole crown 220 is significantly larger than the air outlet surface area of the air outlet hole 211. Therefore, a plurality of air diffusing holes 221 can be added on the hole crown 220, and the total air outlet area of the plurality of air diffusing holes 221 on each hole crown 220 can be designed to be larger than the air outlet surface area of the air outlet hole 211 corresponding to the hole crown 220, thereby effectively increasing the air outlet surface area of the air outlet plate 200.

[0046] According to the technical solution of the present invention, air outlet holes 211 are provided on the air outlet plate 200, and a hole crown 220 covering the air outlet end of the air outlet holes 211 is provided. A plurality of air diffusing holes 221 are provided through the hole crown 220, so that the air flow blown out from the air outlet holes 211 of the air outlet plate 200 is diffused outwards through the air diffusing holes 221 on the hole crown 220. Since the surface area of each hole crown 220 is significantly larger than the area of the air outlet holes 211, the total air outlet area of the plurality of air diffusing holes 221 on each hole crown 220 can be designed to be larger than the air outlet area of the air outlet holes 211 corresponding to the hole crown 220, thereby effectively increasing the air outlet surface area of the air outlet plate 200, and further effectively expanding the air outlet range of the air outlet plate 200, and improving the comfort of the air outlet plate without wind feeling.

[0047] In one embodiment, the air outlet plate 200 is provided with a plurality of air outlet holes 211, and the plurality of air outlet holes 211 are arranged at intervals. Each air outlet hole 211 is correspondingly provided with a hole crown 220. That is to say, any air outlet hole 211 is correspondingly provided with a hole crown 220. The combination of the air diffusing holes 221 of the plurality of hole crowns 220 can greatly increase the air outlet area of the air outlet plate 200 and further expand the air outlet range. Of course, in other embodiments, the hole crown 220 may also be provided only on a part of the air outlet holes 211, and the hole crown 220 may not be provided on the other part of the air outlet holes 211.

[0048] For the hole crown 220, the plurality of air diffusing holes 221 on each hole crown 220 can be arranged at intervals along the circumferential direction of the hole crown 220, so that the orientations of the plurality of air diffusing holes 221 on each hole crown 220 are different, and further each hole crown 220 can supply air to 360° of its circumferential direction, and the air supply range is wider. Of course, in other embodiments, the plurality of air diffusing holes 221 on each hole crown 220 may also be provided on one side surface of the hole crown 220 to achieve one-way air supply, or scattered on the side surface and the top surface of the hole crown 220 to achieve dispersed air supply to different directions.

[0049] For the plurality of hole crowns 220, the orientations of the air diffusing holes 221 of the plurality of hole crowns 220 may be the same or different. In one embodiment, among any two adjacent hole crowns 220, a part of the air diffusing holes 221 of one hole crown 220 are arranged opposite to a part of the air diffusing holes 221 of the other hole crown 220. When the air outlet plate 200 works, a part of the air flow blown out from one hole crown 220 collides with a part of the air flow blown out from the other hole crown 220, so that the air flow blown out from the two hole crowns 220 is further dispersed, and the air flow becomes scattered and disordered, effectively reducing the wind speed and dispersing the wind direction, and further realizing a soft wind feeling and effectively improving the comfort of the air outlet.

[0050] Of course, in other embodiments, among any two adjacent hole crowns 220, a wind blocking wall is formed between two adjacent air dispersion holes 221 of one of the two adjacent hole crowns 220, and part of the air dispersion holes 221 of the other hole crown 220 are arranged opposite to the wind blocking wall of the adjacent hole crown 220. When the air outlet plate 200 works, part of the air flow blown out from one hole crown 220 impacts on the wind blocking wall of the other hole crown 220, is blocked by the wind blocking wall and is dispersed to both sides of the wind blocking wall, and then impacts and disperses again with the air flow blown out from the air dispersion holes 221 on both sides of the wind blocking wall. Under the influence of the multiple cancellation effects, the air flow becomes more disordered, thereby greatly reducing the wind feeling and further enhancing the no-wind feeling effect.

[0051] Based on any of the above embodiments, there can be various shape designs for the specific shape and structure of the hole crown 220. For example but not limited to, the hole crown 220 is arranged in a spherical crown shape; or, the hole crown 220 is arranged in a frustum shape; or, the hole crown 220 is arranged in an umbrella shape. Specifically in this embodiment, the hole crown 220 is arranged in a spherical crown shape. The spherical crown is the part of the sphere remaining after being intercepted by a plane; here, the sphere is a hollow sphere; the air outlet surface of the air outlet plate 200 is the plane for intercepting the sphere to obtain the spherical crown.

[0052] Specifically, when the hole crown 220 is arranged in a spherical crown shape, spherical surfaces are formed on both the inner surface and the outer surface of the hole crown 220, so that the hole crown 220 can have a relatively large three-dimensional surface area, and thus the area for opening the air dispersion holes 221 can be increased, that is, the air outlet surface area can be increased. Moreover, the outer surface of this spherical crown-shaped hole crown 220 also has a regular curvature, which can make the air dispersion angles of the air dispersion holes 221 on the hole crown 220 gradually change along the arrangement direction, so that the air dispersion angles are different from each other, forming multi-directional scattered air supply and greatly reducing the wind feeling.

[0053] As for the method of constructing the hole crown 220 on the air outlet plate 200, the hole crown 220 can be integrally formed with the plate body 210; or, the hole crown 220 can be separately manufactured and then connected and fixed to the plate body 210. This connection method can be secondary injection molding or bonding or welding, etc.

[0054] Based on any of the above embodiments, regarding the size of the hole crown 220, considering that if the height of the hole crown 220 is too small, then the volume of the hole crown 220 is small, and the surface area of the hole crown 220 is also correspondingly reduced, and the area for setting the air dispersion holes 221 is also small; while if the height H of the hole crown 220 is greater than 1.5R, correspondingly, the inner cavity of the hole crown 220 is relatively close to a whole spherical inner cavity, and the air flow may vortex inside and is not easily blown out from the air dispersion holes 221. It can be seen that the height of the hole crown 220 should be kept within a certain range.

[0055] In view of this, research and experiments were conducted on the height of the orifice crown 220, and it was found that when the ratio of the radius R of the air outlet hole 211 to the height H of the orifice crown 220 is maintained in the range of 0.5 ≤ H / R ≤ 1.5, both the air volume and the air velocity of the air diffused by the orifice crown 220 are relatively good, and it is not easy for the air flow to generate eddy current noise in the air diffusing holes 221. Therefore, the ratio of the radius R of the air outlet hole 211 to the height H of the orifice crown 220 should be maintained in the range of 0.5 ≤ H / R ≤ 1.5. That is to say, the height H of the orifice crown 220 conforms to: 0.5R ≤ H ≤ 1.5R. The height H of the orifice crown 220 can specifically be, but is not limited to: 0.5R, 0.8R, R, 1.2R, 1.4R, etc.

[0056] In one embodiment, the radius range of the air outlet hole 211 is 1.5 mm to 5.5 mm. If the radius of the air outlet hole 211 is less than 1.5 mm, the air outlet surface of the air outlet hole 211 is small, the air outlet resistance is large, and the air volume may be insufficient; if the radius of the air outlet hole 211 is greater than 5.5 mm, the air outlet surface of the air outlet hole 211 is large, the air volume is large, the wind speed is fast, and a large noise may be generated when the air flow impacts the orifice crown 220. Therefore, the radius of the air outlet hole 211 should be maintained in the range of 1.5 mm to 5.5 mm to ensure that the air outlet plate 200 obtains a large air volume without generating a large noise. The radius of the air outlet hole 211 can specifically be selected as 1.8 mm, 2 mm, 2.5 mm, 2.8 mm, 3.0 mm, 3.2 mm, 3.5 mm, 4.0 mm, 4.5 mm, 5 mm, etc.

[0057] In one embodiment, the radius range of the air diffusing holes 221 is 1 mm to 6 mm. If the radius of the air diffusing holes 221 is less than 1 mm, the air outlet surface of the air diffusing holes 221 is small, the air outlet resistance is large, and the air flow in the inner cavity of the orifice crown 220 is not easy to blow out from the air diffusing holes 221; if the radius of the air diffusing holes 221 is greater than 6 mm, the air flow in the inner cavity of the orifice crown 220 quickly diffuses out from the air diffusing holes 221, and the air diffusing effect is not good. Therefore, the radius of the air holes should be maintained at 6 mm to ensure that the orifice crown 220 has a better air diffusing effect and a large air diffusing volume at the same time. The radius of the air diffusing holes 221 can specifically be selected as 1.5 mm, 2 mm, 2.5 mm, 3.0 mm, 3.5 mm, 4.0 mm, 4.5 mm, 5.0 mm, 5.5 mm, 5.8 mm, etc.

[0058] Based on any of the above embodiments, the plate body 210 of the air outlet plate 200 can also be provided with a plurality of ventilation holes 212, and the plurality of ventilation holes 212 are dispersedly arranged among the plurality of orifice crowns 220. The air outlet ends of the plurality of ventilation holes 212 are directly exposed on the air outlet surface of the air outlet plate 200 for directly blowing out the air flow to the outside.

[0059] Specifically, multiple ventilation holes 212 and multiple hole crowns 220 are dispersedly arranged, that is to say, multiple ventilation holes 212 are doped and arranged among multiple hole crowns 220, and specifically, regular arrangement or random irregular arrangement is acceptable. For example, multiple ventilation holes 212 and multiple hole crowns 220 are alternately arranged, or one of them is arranged around the other.

[0060] In one embodiment, multiple hole crowns 220 are arranged around the periphery of each ventilation hole 212, and at least part of the air-dispersing holes 221 of each hole crown 220 are open towards the ventilation hole 212. In this way, multiple hole crowns 220 can blow air currents towards the ventilation hole 212, and the air currents blown out by the multiple hole crowns 220 will collide with the air current directly blown out by the ventilation hole 212, and can also disperse the air current, so as to reduce the wind speed and achieve the effect of making the wind feeling softer.

[0061] Certainly, in other embodiments, multiple ventilation holes 212 are arranged around the periphery of each hole crown 220, and multiple air-dispersing holes 221 on the circumference of the hole crown 220 are respectively open towards multiple ventilation holes 212 on its periphery. In this way, the hole crown 220 can disperse air around it, so as to disperse the air current onto multiple ventilation holes 212 on its circumference, and further disperse the air current of the multiple ventilation holes 212, and can also disperse the air current, so as to reduce the wind speed and achieve the effect of making the wind feeling softer. To ensure the air-dispersing effect of the hole crown 220, the radius of the air outlet hole 211 corresponding to the hole crown 220 can be designed to be larger, while the radius of the ventilation hole 212 is designed to be smaller.

[0062] Based on any of the above embodiments, the air outlet plate 200 further includes a mounting bracket 230. The mounting bracket 230 is fixedly connected to the plate body 210 of the air outlet plate 200, and the air outlet plate 200 is suitable for being mounted on the air outlet device through the mounting bracket 230. Specifically, it can be reasonably designed according to the type of the air outlet plate 200 and its mounting position. For example, taking the air outlet plate 200 as a wind guiding plate, the air outlet plate 200 is rotatably mounted on the air outlet 111 of the air outlet device through the mounting bracket 230, so that the air outlet plate 200 can be rotatably unfolded or closed at the air outlet 111 of the air outlet device.

[0063] The present invention provides an air conditioner, and the air conditioner 100 includes a housing 110 and an air outlet panel 200. Among them, the housing 110 is provided with an air inlet and an air outlet duct 111 communicating with the air inlet. The air outlet holes 211 of the air outlet panel 200 communicate with the air outlet duct 111, so that the air flow in the air outlet duct 111 can flow into the hole crown 220 of the air outlet panel 200 only through the air outlet holes 211 of the air outlet panel 200, and then be blown outwards from the hole crown 220. For the specific structure of the air outlet panel 200, refer to the above embodiments. Since the air conditioner 100 adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one. It should be noted that the air conditioner can be any one of a wall-mounted air conditioner indoor unit, a floor-standing air conditioner indoor unit, a mobile air conditioner, and a ceiling-mounted air conditioner.

[0064] In one embodiment, the housing 110 includes a chassis, a front panel disposed on the front side of the chassis, and side panels disposed on both sides of the chassis, and the chassis has a bottom plate. Among them, the front panel, the side panels, and the bottom plate of the chassis can all be the air outlet panel 200.

[0065] For example, the bottom plate of the chassis can be used as the air outlet panel 200, that is to say, air outlet holes 211 are directly formed in the bottom plate, and a hole crown covering the air outlet holes 211 is provided on the bottom plate, so that air can be diffused and sent downward of the air conditioner 100. For another example, the front panel can be used as the air outlet panel 200, that is to say, air outlet holes 211 are directly formed in the front panel, and a hole crown covering the air outlet holes 211 is provided on the front panel, so that air can be diffused and sent forward of the air conditioner 100. For still another example, the side panel can be used as the air outlet panel 200, that is to say, air outlet holes 211 are directly formed in the side panel, and a hole crown covering the air outlet holes 211 is provided on the side panel, so that air can be diffused and sent to the left or right side of the air conditioner 100.

[0066] In one embodiment, the housing 110 is further provided with an air outlet communicating with the air inlet. The air conditioner 100 further includes a wind deflector rotatably installed at the air outlet, and the wind deflector serves as the air outlet panel 200.

[0067] Specifically, the air outlet can be opened on the front side, the lower side, or the left and right sides of the housing 110. The wind deflector 200 is rotatably installed at the air outlet, and can unfold or block the air outlet. When the air conditioner 100 operates in the windless feeling mode, the wind deflector 200 is rotated to a position blocking the air outlet, so that the air flow blown out from the air outlet duct in the housing passes through the air outlet holes 211 of the wind deflector 200 and enters the hole crown 220, and then diffuses and blows out from the air dispersion holes 221 of the hole crown 220.

[0068] The above are only alternative embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present invention.
