Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and in particular to a flow guiding device and an air purifier. Background Technology

[0002] Panel air purifiers use a rotating fan to circulate air, which then flows out from the top vent. To increase the airflow area, the entire top of the product is often designed as an air outlet in the initial stages of product design. However, the truly effective air outlet is usually located directly above the fan, and some products place the control display screen in the center of the air outlet, further reducing the effective airflow area. At the same time, eddies form in the area far from the fan vent, resulting in reduced airflow efficiency, uneven airflow, and unnecessary aerodynamic noise, thus reducing the overall performance of the product.

[0032] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "upper," "lower," "left," "right," "inner," "outer," and similar expressions used in this specification are for illustrative purposes only.

[0033] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0034] In existing air purifiers, the control display screen located in the center of the air outlet occupies a portion of the outlet area. Simultaneously, eddies form in the area away from the fan outlet, reducing airflow efficiency and generating unnecessary aerodynamic noise, thus lowering the overall performance of the product. To address these issues, this application provides an airflow guiding device for use in air purifiers. This device solves the problems of low airflow efficiency and high aerodynamic noise in existing air purifiers, while simultaneously improving airflow efficiency and reducing aerodynamic noise.

[0035] In some embodiments, such as Figures 1-5 As shown, a flow guiding device 1 is provided, which is applied to an air purifier and includes:

[0036] The main body 11 is located at the air outlet 22 of the air purifier; the main body 11 is provided with a first guide surface 13, a second guide surface 14, a third guide surface 15 and a fourth guide surface 16 on the side facing the air outlet of the air purifier.

[0037] In the horizontal direction, the first guide surface 13 is adjacent to the second guide surface 14 and the fourth guide surface 16, and the third guide surface 15 is adjacent to the second guide surface 14 and the fourth guide surface 16;

[0038] A tapering channel 26 is formed between the second guide surface 14 and the air purifier.

[0039] As the airflow passes through the guide device 1 from bottom to top, the first guide surface 13, the second guide surface 14, the third guide surface 15, and the fourth guide surface 16 divide the airflow, making the airflow more uniform. When the high-speed airflow passes through the narrowing channel 26 formed between the second guide surface 14 and the air purifier, the flow area decreases, the flow resistance increases, and some gas flows to both sides, increasing the airflow volume on both sides of the narrowing channel 26, thus improving the overall airflow volume and uniformity. After applying the guide device 1, the airflow volume and airflow uniformity of the air purifier are optimized. While ensuring the expected airflow volume, the fan speed of the air purifier 25 can be reduced, reducing unnecessary aerodynamic noise and thus achieving the effect of noise reduction.

[0040] In some embodiments, the angle between the second guide surface 14 and the horizontal plane is β, where 10°≤β≤50°. By limiting the angle between the second guide surface 14 and the horizontal plane, a narrowing channel 26 is formed between the second guide surface 14 and the air purifier. When the high-speed airflow passes through the narrowing channel 26, the flow area decreases, the flow resistance increases, and some gas flows to both sides, thereby increasing the air volume on both sides of the narrowing channel 26. This solves the problem that the air volume of existing air purifiers is concentrated above the fan 25, improving the overall air volume and air volume uniformity.

[0041] In some embodiments, the angle between the first guide surface 13 and the horizontal plane is α, 10°≤α≤50°; the angle between the second guide surface 14 and the horizontal plane is β, 10°≤β≤50°; the angle between the third guide surface 15 and the horizontal plane is γ, 45°≤γ≤90°; and the angle between the fourth guide surface 16 and the horizontal plane is δ, 45°≤δ≤90°. When the airflow passes through the guide device 1 from bottom to top, the first guide surface 13, the second guide surface 14, the third guide surface 15, and the fourth guide surface 16 divert the airflow, preventing the airflow from concentrating directly above the fan 25, thus making the airflow more uniform.

[0042] In some embodiments, such as Figure 1 As shown, the first guide surface 13 is connected to the second guide surface 14 and the fourth guide surface 16 via arc surfaces 17, and the third guide surface 15 is also connected to the second guide surface 14 and the fourth guide surface 16 via arc surfaces 17. By setting the adjacent guide surfaces to transition via arc surfaces 17, the arc surfaces 17 can buffer the airflow, making the airflow gentler and helping to reduce airflow noise.

[0043] In some embodiments, such as Figure 1 As shown, the first guide surface 13 and the third guide surface 15 are arranged opposite to each other, and the second guide surface 14 and the fourth guide surface 16 are arranged opposite to each other. The first guide surface 13 and the third guide surface 15 have triangular cross-sectional shapes, while the second guide surface 14 and the fourth guide surface 16 have trapezoidal shapes. The second guide surface 14 and the fourth guide surface 16 are connected, and the connection point forms a rounded corner 18, which faces the air purifier's outlet direction. When the airflow passes through the guide device 1, it first flows through the rounded corner 18. The rounded corner 18 guides more airflow to the second guide surface 14, thereby allowing more airflow to enter the converging channel 26, increasing the airflow volume on both sides of the converging channel 26, and improving the overall airflow volume and uniformity. In other embodiments, the connection point of the second guide surface 14 and the fourth guide surface 16 forms a line, which also guides the airflow to the second guide surface 14, thereby allowing more airflow to enter the converging channel 26.

[0044] In some embodiments, such as Figure 1 , Figure 2 and Figure 5 As shown, the main body 11 is provided with a snap-fit ​​part 12, and the main body 11 is connected to the air purifier through the snap-fit ​​part 12. By providing the snap-fit ​​part 12, it is convenient to assemble and use the air guide device 1 with the air purifier.

[0045] In some embodiments, the main body 11 can also be connected to the air outlet grille 23 by means of magnetic attraction, plug-in or screw connection, as long as it can be easily installed and disassembled, and there is no limitation.

[0046] In some embodiments, the center of the air purifier outlet 22 is a display screen, and the main body 11 is installed at the position of the display screen by means of the buckle part 12, so that the air guiding device 1 guides the airflow and reduces the airflow obstruction caused by the display screen.

[0047] In some embodiments, such as Figures 1-5 As shown, an air purifier is provided, comprising:

[0048] The housing 2 is provided with an air inlet 21 and an air outlet 22, and an air outlet grille 23 is provided at the air outlet 22;

[0049] Vortex housing 24, the vortex housing 24 is disposed inside the housing 2, the vortex housing 24 is provided with an amplification section 241, the amplification section 241 faces the air outlet grille 23;

[0050] Fan 25, the fan 25 is disposed inside the volute, the fan 25 takes in air through the air inlet 21 and exits air through the amplification section 241;

[0051] A flow guiding device 1 is connected to the air outlet grille 23; the flow guiding device 1 is provided with a first flow guiding surface 13, a second flow guiding surface 14, a third flow guiding surface 15 and a fourth flow guiding surface 16 on the side facing the expansion section 241;

[0052] In the horizontal direction, the first guide surface 13 is adjacent to the second guide surface 14 and the fourth guide surface 16, the third guide surface 15 is adjacent to the second guide surface 14 and the fourth guide surface 16, and a tapered channel 26 is formed between the second guide surface 14 and the amplification section 241.

[0053] As the airflow passes through the guide device 1 from bottom to top, the first guide surface 13, the second guide surface 14, the third guide surface 15, and the fourth guide surface 16 divide the airflow, making the airflow more uniform. When the high-speed airflow passes through the tapered channel 26 formed between the second guide surface 14 and the expansion section 241, the flow area decreases, the flow resistance increases, and some gas flows to both sides, increasing the airflow volume on both sides of the tapered channel 26, thus improving the overall airflow volume and uniformity. After applying the guide device 1, the airflow volume and airflow uniformity of the air purifier are optimized. While ensuring the expected airflow volume, the fan speed of the air purifier 25 can be reduced, reducing unnecessary aerodynamic noise and thus achieving the effect of noise reduction.

[0054] In some embodiments, the fan 25 includes a motor and turbine blades, with the motor driving the turbine blades to rotate to generate airflow.

[0055] In some embodiments, the angle between the second guide surface 14 and the horizontal plane is β, where 10°≤β≤50°. By limiting the angle between the second guide surface 14 and the horizontal plane, a tapered channel 26 is formed between the second guide surface 14 and the expansion section 241. When the high-speed airflow passes through the tapered channel 26, the flow area decreases, the flow resistance increases, and some gas flows to both sides, thereby increasing the air volume on both sides of the tapered channel 26. This solves the problem that the air volume of existing air purifiers is mainly concentrated above the fan 25, improving the overall air volume and air volume uniformity.

[0056] In some embodiments, the angle between the first guide surface 13 and the horizontal plane is α, 10°≤α≤50°; the angle between the second guide surface 14 and the horizontal plane is β, 10°≤β≤50°; the angle between the third guide surface 15 and the horizontal plane is γ, 45°≤γ≤90°; and the angle between the fourth guide surface 16 and the horizontal plane is δ, 45°≤δ≤90°. When the airflow passes through the guide device 1 from bottom to top, the first guide surface 13, the second guide surface 14, the third guide surface 15, and the fourth guide surface 16 divert the airflow, preventing the effective air outlet from being mainly concentrated directly above the fan 25, thus making the airflow more uniform.

[0057] In some embodiments, such as Figure 1 and Figure 5 As shown, the airflow guiding device 1 is provided with a snap-fit ​​part 12, which is connected to the air outlet grille 23. By providing the snap-fit ​​part 12, it is convenient for the airflow guiding device 1 to be directly assembled to the air outlet grille 23.

[0058] In some embodiments, the airflow guiding device 1 can also be connected to the air outlet grille 23 by means of magnetic attraction, plug-in connection, screw connection, etc., which is not limited here.

[0059] In some embodiments, the air purifier is a panel air purifier.

[0060] In some embodiments, the angle α between the first guide surface 13 and the horizontal plane is 23.57°, the angle β between the second guide surface 14 and the horizontal plane is 28.13°, the angle γ between the third guide surface 15 and the horizontal plane is 71.8°, and the angle δ between the fourth guide surface 16 and the horizontal plane is 90°. The following table shows a comparison between air purifiers with and without the guide surface 1 after the guide surface 1 is installed:

[0061]

[0062] Table 1

[0063] By comparing data 1 and data 2, it can be seen that, at the same fan speed of 25, the air purifier with the added airflow guide device 1 has significantly improved performance and increased air volume.

[0064] Comparing data 1, 3, 4, and 5 reveals that, to achieve the same product performance, the air purifier equipped with the airflow guide device 1 has a lower fan speed (25). While maintaining the expected airflow volume, the reduced fan speed (25) lowers unnecessary aerodynamic noise, thus achieving a noise reduction effect. Of course, the angle between each airflow guide surface and the horizontal plane can be selected according to requirements and is not limited here.

[0065] In some embodiments, such as Figure 5 As shown, a first airflow channel is formed between the first guide surface 13 and the amplification section 241, a second guide surface 14 is formed between the second guide surface 14 and the amplification section 241, a third guide surface 15 is formed between the third guide surface 15 and the amplification section 241, and a fourth guide surface 16 is formed between the fourth guide surface 16 and the amplification section 241. The second guide surface is the tapered channel 26.

[0066] like Figure 6 As shown, the air outlet grille 23 is divided into a first air outlet zone 231, a second air outlet zone 232, a third air outlet zone 233, and a fourth air outlet zone 234. The first guide surface 13 guides the airflow in the first guide channel to the first air outlet zone 231 and the second air outlet zone 232 for outlet. The second guide surface 14 guides the airflow in the second guide channel to the second air outlet zone 232 and the third air outlet zone 233 for outlet. The third guide surface 15 guides the airflow in the third guide channel. The fourth airflow guide surface 16 guides the airflow in the fourth airflow guide channel to the fourth airflow guide zone 234 and the first airflow guide zone 231. The first airflow guide channel and the second airflow guide channel increase the airflow volume of the second airflow guide zone 232 and the third airflow guide zone 233. The airflow guide device 1 makes up for the problem of insufficient airflow volume in the second airflow guide zone 232 and the third airflow guide zone 233 of the existing air purifier, and improves the overall airflow volume and airflow uniformity.
