Description

Technical Field

[0001] The utility model relates to the technical field of air treatment, in particular to an air treatment device. Background Art

[0002] Currently, ventilation equipment and other devices, such as noise treatment equipment, are often accompanied by fan or duct noise during use. Therefore, to improve the operating environment, silencing modules are often incorporated into ventilation equipment and other devices. However, in actual use, silencing modules cannot simultaneously address both airflow resistance and noise reduction, resulting in a trade-off between energy efficiency and comfort. Utility Model Content

[0003] In view of this, the present invention provides a silencer module and ventilation equipment to solve the problem that the resistance of the wind flow and the degree of noise reduction cannot be taken into account at the same time.

[0004] In a first aspect, the present invention provides an air treatment device, the air treatment device comprising:

[0005] The wind cabinet is provided with an air duct, wherein the air duct is provided with an air inlet side and an air outlet side;

[0006] A first silencer module is provided on the air inlet side of the air duct;

[0007] and / or, a second silencer module, disposed on the air outlet side of the air duct;

[0008] The first silencer module and the second silencer module are both composed of a plurality of silencer units; the plurality of silencer units are arranged along the wind flow direction;

[0009] The muffler unit is provided with a plurality of muffler plates, which are arranged in the same direction, and a gap is provided between two adjacent muffler plates;

[0010] The silencer plate is provided with a windward angle at a position close to the air inlet side, and / or the silencer plate is provided with a windward angle at a position close to the air outlet side.

[0011] Beneficial Effects: This embodiment arranges multiple muffler panels in the same direction, dividing the airflow into multiple muffler spaces. Within each muffler space, the muffler panels utilize their numerous tiny interconnected pores to muffle the sound. Sound waves generated by the airflow passing through the muffler panels travel deep into the panels along their micropores, creating friction with the panels' internal material, converting the sound energy into heat energy, resulting in a sound-reducing unit with excellent noise reduction. Furthermore, this embodiment reduces wind resistance when the airflow passes through the panels by setting a windward angle, thereby reducing the sound produced by friction between the airflow and the panels and reducing energy loss. Furthermore, the muffler panels are provided with a windward angle. When the airflow passes the rear end of the muffler panel, the windward angle separates the rear end of the muffler panel and enhances the flow characteristics of the airflow, reducing noise generated by turbulence in the rear end of the muffler panel to a certain extent, further improving the muffler's performance. Furthermore, this embodiment provides a windward angle and a wind-leaving angle on the silencer plate, which is equivalent to a fool-proof design of the silencer plate, thereby facilitating maintenance and disassembly by technical personnel.

[0012] In an optional embodiment, the multiple silencer units include a first silencer unit, and the first silencer unit is provided with multiple first silencer plates. The first silencer plates are in a straight plate structure, and the first silencer plates are tilted so that a first angle is set between the plane where the first silencer plates are located and the air inlet direction.

[0013] In an optional embodiment, the multiple silencer units include a second silencer unit, and the second silencer unit is provided with multiple second silencer plates. The second silencer plates are in a straight plate structure, and the plane where the second silencer plates are located is parallel to the air inlet direction.

[0014] In an optional embodiment, the multiple silencer units include a third silencer unit, and the third silencer unit is provided with multiple third silencer plates; the third silencer plate includes a first plate and a second plate that are bent to each other, so that the third silencer plate has a V-shaped structure; and a second angle is set between the planes where the first plate and the second plate are located.

[0015] In an optional embodiment, the first silencer module and the second silencer module are both provided with one or more of a first silencer unit, a second silencer unit, and a third silencer unit.

[0016] In an optional embodiment, the first silencer module and the second silencer module are each provided with only one of the first silencer unit, the second silencer unit, and the third silencer unit.

[0017] In an optional embodiment, when only first silencer units are provided in the first silencer module and the second silencer module, the inclination directions of the first silencer plates in two adjacent first silencer units are opposite.

[0018] In an optional embodiment, the inclination angles of the first sound-absorbing plates in two adjacent first sound-absorbing units are the same or different.

[0019] In an optional embodiment, when the inclination angles are different, along the wind flow direction, the inclination angle of the first silencer plate in each first silencer unit gradually decreases or gradually increases.

[0020] In an optional embodiment, when the multiple silencer units are arranged, two adjacent silencer units are abutted and sealed, and / or the outer wall of the silencer unit is abutted and sealed with the inner wall of the air duct.

[0021] In an optional embodiment, the muffler unit further includes:

[0022] The supporting frame is provided with a receiving cavity inside; the supporting frame is provided with an air inlet side and an air outlet side; a plurality of silencer plates are arranged in the receiving cavity in the same direction.

[0024] In an optional embodiment, a sealing strip is provided around the edge of the support frame.

[0025] In an optional embodiment, the sealing strip is made of sealing sponge.

[0026] Beneficial Effects: This embodiment utilizes a sealing sponge as the sealing strip. Due to its characteristic of slowly recovering to its original shape, the sealing sponge deforms when subjected to pressure, but slowly returns to its original shape when the pressure is released. This characteristic allows the sealing sponge to better adapt to the irregular vibrations and dynamic environment generated by the silencer unit during operation. Furthermore, the sealing sponge's excellent sealing properties prevent air leakage through gaps, reducing noise caused by air flow and improving the overall sound insulation of the silencer unit.

[0027] In an optional embodiment, the thickness of the sealing sponge is between 2 mm and 5 mm.

[0028] In an optional embodiment, a handle is provided on the support frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0049] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0050] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; they may refer to internal connections between two components; they may refer to wireless connections or wired connections. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0051] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0052] Currently, ventilation equipment and other devices, such as noise treatment equipment, are often accompanied by fan or duct noise during use. Therefore, to improve the operating environment, silencing modules are often incorporated into ventilation equipment and other devices. However, in actual use, silencing modules cannot simultaneously address both airflow resistance and noise reduction, resulting in a trade-off between energy efficiency and comfort.

[0053] In view of this, the present invention provides a silencer module and ventilation equipment to solve the problem that the resistance of the wind flow and the degree of noise reduction cannot be taken into account at the same time.

[0054] The following combination Figures 1 to 14 , describing the embodiments of the present utility model.

[0055] According to an embodiment of the present invention, on one hand, an air treatment device is provided. The air treatment device includes: an air cabinet 1 , a first silencer module 2 , and a second silencer module 3 .

[0056] Specifically, in this embodiment, Figure 1 and Figure 8 As shown, the air cabinet 1 is provided with an air inlet side and an air outlet side. In actual use, the first silencer module 2 can be installed only on the air inlet side, or the second silencer module 3 can be installed only on the air outlet side. Of course, to further enhance the overall sound-absorbing effect of the air treatment equipment, the first silencer module 2 or the second silencer module 3 can be installed at the same time.

[0057] Furthermore, in this embodiment, if Figure 1 and Figure 8 As shown, each of the first and second muffler modules 2 and 3 is composed of multiple muffler units, which are arranged along the airflow direction. That is, when the air enters, the airflow will sequentially pass through the multiple muffler units of the first muffler module 2 for muffler, and then when the airflow passes through the second muffler module 3, it will also sequentially pass through the multiple muffler units of the second muffler module 3 for muffler.

[0058] Furthermore, in this embodiment, the silencer unit is provided with a plurality of silencer plates 9, and the plurality of silencer plates 9 are arranged in the same direction, and a gap is provided between two adjacent silencer plates 9. Specifically, the silencer plates 9 can be fixedly provided in the silencer unit, or can be movably provided in the silencer unit. As for the installation direction of the silencer plates 9, when the silencer plates 9 are flat plates, the plate surface of the silencer plates 9 can be provided parallel to the air inlet direction, or can be provided at an angle. When the silencer plates 9 are corrugated plates or other types of plate surfaces with a certain bending angle, the overall extension direction of the silencer plates 9 can be provided parallel to the air inlet direction. In this way, the contact length between the silencer plates 9 and the airflow can be increased as much as possible, thereby increasing the silencer effect of the silencer plates 9.

[0059] Of course, those skilled in the art can change the installation direction of the silencer plate 9 according to actual conditions. This embodiment is only an example for illustration, but is not intended to limit this. It only needs to achieve the same technical effect.

[0060] Furthermore, in this embodiment, Figure 4 As shown, the muffler plate 9 is provided with a windward angle 7 near the air inlet side, and a windward angle 8 near the air outlet side. In other words, the side of the muffler plate 9 near the air inlet side is provided with a windward angle 7, and the side near the air outlet side is provided with a windward angle 8. Of course, only the windward angle 7 or the windward angle 8 can also be provided. This embodiment is merely an example.

[0061] This embodiment arranges multiple muffler panels 9 in the same direction, dividing airflow into multiple muffler spaces as it passes through. Within each muffler space, the panels 9 utilize their numerous, interconnected pores to attenuate sound. Sound waves generated by airflow passing through the panels 9 penetrate deeply into the panels along their micropores, creating friction with the panels' internal material, converting the sound energy into heat. This results in a superior noise reduction effect for the muffler unit. Furthermore, this embodiment employs a windward angle 7 on the panels 9 to reduce wind resistance as airflow passes through them, thereby minimizing the noise generated by friction between the airflow and the panels and reducing energy loss. Furthermore, the panels 9 are provided with a windward angle 8. This angle separates the airflow at the rear of the panels as it passes through them, enhancing the flow characteristics of the airflow and reducing noise generated by turbulence at the rear, further enhancing the muffler's effectiveness. Furthermore, this embodiment provides a windward angle 7 and a wind departure angle 8 on the silencer plate 9, which is equivalent to a fool-proof design for the silencer plate 9, thereby facilitating maintenance and disassembly by technicians.

[0062] Furthermore, in an optional embodiment, multiple types of silencer units are provided, and the silencer plates 9 in each silencer unit are arranged differently. For example, the silencer plates 9 can be arranged in parallel or crosswise, etc. Of course, this embodiment is merely an example of the arrangement of the silencer plates 9 in the silencer units, but is not intended to be limiting. Those skilled in the art may modify the arrangement according to actual circumstances.

[0063] Specifically, in this embodiment, Figures 2 to 4 , Figures 9 to 14 As shown, the types of the silencer units are illustrated by taking the first silencer unit 4 , the second silencer unit 5 and the third silencer unit 6 as examples.

[0064] For the first muffler unit 4, Figures 2 to 4 As shown, the first muffler unit 4 is provided with a plurality of first muffler panels 41. The first muffler panels 41 are straight and inclined, such that a first angle E is formed between the plane where the first muffler panels 41 are located and the air inlet direction. In other words, within the first muffler unit 4, all the first muffler panels 41 are inclined in the same direction.

[0065] Furthermore, in an optional embodiment, the parameters and the noise reduction effect of the first noise reduction unit 4 are described in detail.

[0066] In the embodiment of the present invention, the length of the first muffler unit 4, the gap, and the thickness of the muffler plate 9 have the following numerical relationship:

[0067] like Figure 4 As shown, the length of the silencer unit is A, and the length direction of the silencer unit is the air inlet direction. Of course, in this embodiment, the length of the silencer unit can be the same as the outer length of the support frame 10. When the thickness of the support frame 10 can be ignored, the length of the silencer module can be the same as the length of the silencer plate 9. The specific dimensions need to be selected by technicians according to actual conditions and are not limited here.

[0068] The gap is B, which is between 0.1A and 0.2A;

[0069] The thickness of the first silencer plate 41 is C, and C is between 0.06A and 0.2A; wherein the thickness direction of the first silencer plate 41 is perpendicular to the air inlet direction.

[0070] Further, in an optional embodiment, the first angle E is between 0° and 90°.

[0071] Laboratory tests were conducted with V = 3m / s, B = 0.2A, C = 0.12A, and E = 45°, following the recommended parameters for noise reduction comparison. The test results under different A values ​​are as follows:

[0072] A value (m) 0.1 0.15 0.2 Noise reduction value (dB) 7 8 10 Wind resistance (Pa) 6 6 8

[0073] In this way, this embodiment sets the parameters of the silencer unit and the first silencer plate 41 as above. A large amount of experimental data can prove that within the above parameter range, the silencer effect of the silencer module can be significantly improved, while also reducing the sound generated by the friction between the wind flow and the first silencer plate 41, thereby reducing energy loss.

[0074] On this basis, the reference data for noise reduction comparison tests with different numbers of module combinations are as follows:

[0075] When two silencer units are placed side by side, the noise level is reduced by 11dB, but the wind resistance increases by 10Pa;

[0076] When three silencer units are arranged side by side, the noise level is reduced by 14dB, but the wind resistance increases by 15Pa.

[0077] When four silencer units are arranged side by side, the noise level is reduced by 16dB, but the wind resistance is increased by 18Pa.

[0078] Furthermore, in an optional embodiment, as Figures 9 to 11 As shown, a plurality of second silencer plates 51 are provided in the second silencer unit 5 . The second silencer plates 51 are in a straight plate structure, and the plane where the second silencer plates 51 are located is parallel to the air inlet direction.

[0079] Laboratory tests were conducted with V = 3m / s, B = 0.2A, and C = 0.12A, following the recommended parameters for noise reduction comparison. The test results under different A values ​​are as follows:

[0080] A value (m) 0.1 0.15 0.2 Noise reduction value (dB) 8 9 10 Wind resistance (Pa) 8 8 9

[0081] Furthermore, in an optional embodiment, as Figures 12 to 14 As shown, a plurality of third silencer plates 61 are provided in the third silencer unit 6; the third silencer plates 61 include a first plate and a second plate that are bent to each other, so that the third silencer plates 61 have a V-shaped structure; and a second angle F is provided between the planes where the first plate and the second plate are located.

[0082] Laboratory tests were conducted with V = 3m / s, B = 0.2A, and C = 0.12A, following the recommended parameters for noise reduction comparison. The test results under different A values ​​are as follows:

[0083] A value (m) 0.1 0.15 0.2 Noise reduction value (dB) 9 10 12 Wind resistance (Pa) 9 9 11

[0084] Furthermore, in an optional embodiment, the first silencer module 2 and the second silencer module 3 are both provided with one or more of the first silencer unit 4, the second silencer unit 5, and the third silencer unit 6. In other words, each silencer unit can be combined and mixed in the first silencer module 2 and the second silencer module 3 to achieve different silencer effects. Figure 8 As shown, a combination of the second silencer unit 5 and the third silencer unit 6 is adopted.

[0085] The following content is described by taking the combination of the first muffler module 2 as an example.

[0086] The first silencer module 2 may be provided with only one of the first silencer unit 4 , the second silencer unit 5 , and the third silencer unit 6 .

[0087] The first muffler module 2 may also be provided with two of the first muffler unit 4, the second muffler unit 5, and the third muffler unit 6, for example, the first muffler unit 4 and the second muffler unit 5. When arranged, the first muffler unit 4 and the second muffler unit 5 may be placed alternately, or all the first muffler units 4 may be placed upstream of the second muffler unit 5.

[0088] Similarly, the first muffler module 2 can also be provided with the first muffler unit 4, the second muffler unit 5, and the third muffler unit 6. As for the placement order, this embodiment will not be described in detail. Those skilled in the art can change it according to actual conditions as long as the same technical effect can be achieved.

[0089] Furthermore, in an optional embodiment, each of the first silencer module 2 and the second silencer module 3 is provided with only one of the first silencer unit 4 , the second silencer unit 5 , and the third silencer unit 6 .

[0090] Furthermore, in an optional embodiment, when only the first silencer unit 4 is provided in the first silencer module 2 and the second silencer module 3, the first silencer plates 41 in two adjacent first silencer units 4 have opposite inclination directions. Figure 1 and Figure 5 shown.

[0091] Furthermore, in an optional embodiment, the inclination angles of the first silencer plates in two adjacent first silencer units are the same or different. That is, the inclination angles of the first silencer plates in two adjacent first silencer units can be the same, for example, 30°, 40°, 50°, etc. For the case where the inclination angles are different, those skilled in the art can make adjustments according to actual conditions. For example, along the wind direction, the inclination angle of the first silencer plate in the first first silencer unit can be 30°, the inclination angle of the first silencer plate in the second first silencer unit can be 35°, the inclination angle of the first silencer plate in the third first silencer unit can be 40°, and the inclination angle of the first silencer plate in the fourth first silencer unit can be 45°.

[0092] Of course, after adopting the installation method in which the first silencer plate is movably arranged in the first silencer unit, technical personnel in this field can make adjustments according to actual conditions. For example, the inclination angle of the first silencer plate in one or more of the first silencer units can be changed separately, so that the operation of the air treatment equipment is more in line with the actual use environment.

[0093] Furthermore, in an optional embodiment, when the inclination angles are different, along the wind flow direction, the inclination angle of the first silencer plate in each first silencer unit gradually decreases or gradually increases.

[0094] When the inclination angle gradually becomes smaller, for example, along the wind direction, the inclination angle of the first silencer plate in the first first silencer unit can be 45°, the inclination angle of the first silencer plate in the second first silencer unit can be 40°, the inclination angle of the first silencer plate in the third first silencer unit can be 35°, and the inclination angle of the first silencer plate in the fourth first silencer unit can be 30°.

[0095] When the inclination angle gradually becomes larger, for example, along the wind direction, the inclination angle of the first silencer plate in the first first silencer unit can be 45°, the inclination angle of the first silencer plate in the second first silencer unit can be 40°, the inclination angle of the first silencer plate in the third first silencer unit can be 35°, and the inclination angle of the first silencer plate in the fourth first silencer unit can be 30°.

[0096] Of course, this embodiment is only an example to illustrate the specific numerical value of the tilt angle, but it is not limited to this. Those skilled in the art can make changes according to actual conditions as long as the same technical effect can be achieved.

[0097] Further, in an alternative embodiment, the plurality of sound attenuation units are arranged in abutment sealing between adjacent sound attenuation units and between the outer wall of the sound attenuation unit and the inner wall of the air duct. In this way, the air flow through the sound attenuation units can be prevented from flowing out of the gap between adjacent sound attenuation units and from flowing through the gap between the sound attenuation unit and the air duct, thereby increasing the overall sound attenuation capacity of the air handling device.

[0098] Of course, the skilled person can only abut sealing between adjacent sound attenuation units or between the outer wall of the sound attenuation unit and the inner wall of the air duct, and the present embodiment is only an example, but not limited thereto, which can achieve the same technical effect.

[0099] Further, in an alternative embodiment, as shown in FIG. 9, a straight plate type sound attenuation plate 9 is taken as an example. The sound attenuation plate 9 is composed of a first cover plate 91, a first fixing member 92, a sound attenuation material 93, a second fixing member 94, and a second cover plate 95 stacked in the vertical direction. Figure 6 The sound attenuation material 93 has a large number of micro-holes inside, and the sound wave penetrates into the sound attenuation material 93 through the micro-holes on the inner surface, and the sound energy is converted into heat energy through friction with the sound attenuation material 93.

[0100] Further, in an alternative embodiment, a through hole is provided on the first cover plate 91 and the second cover plate 95, the aperture of the through hole is d, d is between 1mm and 5mm, and the hole distance D is between 1.2d and 2d.

[0101] Further, in an alternative embodiment, the first cover plate 91 and the second cover plate 95 are made of metal material or engineering plastic, and the thickness of the first cover plate 91 and the second cover plate 95 is between 0.5mm and 2mm.

[0102] Further, in an alternative embodiment, the first fixing member 92 and the second fixing member 94 are non-woven fabrics, and the specification of the first fixing member 92 and the second fixing member 94 is 20g / m2 to 120g / m2.

[0103] Further, in an alternative embodiment, the sound attenuation material 93 at least includes polyester fiber, glass fiber, mineral wool, and rubber.

[0104] Further, in an alternative embodiment, the sound attenuation material 93 is sound attenuation cotton, which is made of polyester fiber, and the specification of the sound attenuation cotton is between 40kg / m2 and 120kg / m2. 3 3

[0105] ​​Furthermore, in an optional embodiment, the silencer unit further includes a support frame 10 with a receiving cavity provided therein. The support frame 10 is provided with an air inlet side and an air outlet side, and a plurality of silencer plates 9 are arranged in the same direction in the receiving cavity.

[0106] Specifically, in an embodiment of the present invention, the support frame 10 can be composed of four separate support plates combined into a rectangular frame, or can be composed of two separate bent plates combined into a rectangular frame, each bent plate including a horizontally arranged support plate and a vertically arranged support plate. A accommodating cavity is provided inside the rectangular frame. After the rectangular frame is erected, the bottom support plate contacts the ground, two side support plates are erected on both sides of the bottom support plate, the top support plate is arranged opposite to the bottom support plate, and both sides of the top support plate are connected to the two side support plates respectively.

[0107] On this basis, along the vertical direction, the rectangular through holes on both sides surrounded by the rectangular frame are respectively the air inlet side and the air outlet side.

[0108] Furthermore, in an optional embodiment, the support frame 10 is made of metal or engineering plastic, facilitating overall maintenance and replacement within the equipment or ventilation duct. The support frame 10 includes, but is not limited to, rectangular and circular shapes, and can also be shaped in other ways to accommodate the specific noise reduction equipment or duct.

[0109] Furthermore, in an optional embodiment, a sealing strip 11 is provided around the edge of the support frame 10 .

[0110] Furthermore, in an optional embodiment, the sealing strip 11 is made of sealing sponge.

[0111] This embodiment utilizes a sealing sponge as the sealing strip 11. Due to its characteristic of slowly recovering to its original shape, the sealing sponge deforms when subjected to pressure, but slowly returns to its original shape when the pressure is released. This characteristic allows the sealing sponge to better adapt to the irregular vibrations and dynamic environment generated by the silencer unit during operation. Furthermore, the sealing sponge's excellent sealing properties prevent air from leaking through gaps, reducing noise caused by air flow and improving the overall sound insulation of the silencer unit.

[0112] Furthermore, in an optional embodiment, the thickness of the sealing sponge is between 2 mm and 5 mm, so that the entire assembly and disassembly can be facilitated for maintenance.

[0113] Furthermore, in an optional embodiment, a handle is provided on the support frame 10 .

[0114] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope of the appended claims.
