Description

Technical Field

[0001] This utility model relates to the field of air conditioning compressor technology, and more specifically, it relates to a noise reduction structure for an air conditioning compressor silencer package. Background Technology

[0002] With the rapid development of modern industrial technology, the performance and efficiency of air conditioning compressors, as key components of modern refrigeration equipment, are crucial for improving the overall operating effect of air conditioning systems. However, air conditioning compressors generate considerable noise during operation.

[0003] For example, the silencer and air conditioner including the silencer disclosed in authorization announcement number CN103292450B include a cylinder body with an integrally continuous interior. The cylinder body is located in the middle, and an air inlet and an air outlet are respectively provided at both ends. The cross-sectional areas of the air inlet and the air outlet are smaller than the cross-sectional area of ​​the inner cavity of the cylinder body. An air inlet connecting pipe with a cross-sectional area smaller than the cross-sectional area of ​​the inner cavity of the cylinder body is connected to the air inlet. An air outlet connecting pipe with a cross-sectional area smaller than the cross-sectional area of ​​the inner cavity of the cylinder body is connected to the air outlet. The cylinder body is made of an elastic material.

[0004] As mentioned above, the air conditioner compressor generates a lot of low-frequency noise during operation. The noise is eliminated by using a cylinder made of elastic material, but there is no structure inside the cylinder, making it difficult to effectively eliminate low-frequency noise and resulting in poor noise reduction. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a noise reduction structure for an air conditioner compressor noise reduction package that improves the noise reduction effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A noise reduction structure for an air conditioner compressor silencer includes a frame with an air inlet and an air outlet, both located on opposite sides of the frame.

[0008] The frame contains silencing chambers, which are connected to the air inlet and outlet.

[0009] The inner wall of the anechoic chamber is equipped with several assembly components that are fixedly connected to the inner wall of the anechoic chamber. Adjacent assembly components are fixed together.

[0010] The assembly includes a first connecting plate and a second connecting plate.

[0011] The first connecting plate and the second connecting plate are perpendicularly distributed and fixed to each other.

[0012] Both the first connecting plate and the second connecting plate are provided with a first air guide plate and a second air guide plate. One side of the first air guide plate is fixed to one side of the first connecting plate, and one side of the second air guide plate is fixed to the other side of the first connecting plate. The first connecting plate, the first air guide plate on the first connecting plate, the second air guide plate on the first connecting plate, and the second connecting plate, together with the inner wall of the silencing chamber, form a bouncing space for noise to bounce.

[0013] The first air guide plate includes a first slope and a second slope, the first slope and the second slope are fixedly connected, and the first slope, the second slope and the second air guide plate are all inclined.

[0014] The present invention is further configured such that: the air outlet is provided with an installation frame, the installation frame is provided with an air guide port and several exhaust ports, the air guide port is connected to the air outlet, and the installation frame has an air storage chamber, which is connected to the air guide port and the exhaust ports.

[0015] The present invention is further configured such that: the gas storage chamber is provided with an upper support plate, a middle support plate and a lower support plate, the middle support plate is placed between the upper support plate and the lower support plate, and a number of noise reduction holes communicating with the gas storage chamber are opened on the upper support plate, the middle support plate and the lower support plate.

[0016] The present invention is further configured such that the number of noise reduction holes on the upper support plate is less than the number of noise reduction holes on the middle support plate and less than the number of noise reduction holes on the lower support plate.

[0017] The present invention is further configured such that the sound-absorbing chamber is filled with sound-absorbing cotton.

[0018] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0019] When noise travels into the anechoic chamber, it first collides with the assembled components. During this collision, the noise undergoes reflection, refraction, and scattering, causing it to bounce within the space. As it bounces, the noise's energy is gradually dissipated and dispersed. The mounting frame at the air outlet lengthens the noise path, further reducing noise and improving the anechoic effect. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] like Figs. 1 to 3 As shown, the noise reduction structure of the air conditioner compressor noise reduction package includes a frame 1, with an air inlet 2 and an air outlet 3 on the frame 1. The air inlet 2 and the air outlet 3 are on both sides of the frame 1. The frame 1 has a noise reduction chamber 4. Noise enters from the air inlet 2, passes through the noise reduction chamber 4, and then exits from the air outlet 3 to form a noise reduction path.

[0028] The silencing chamber 4 is filled with sound-absorbing cotton, which can eliminate the noise entering the silencing chamber 4. There are several assembly components on the inner wall of the silencing chamber 4. Adjacent assembly components are fixed. The assembly components include a first connecting plate 5 and a second connecting plate 6. The first connecting plate 5 and the second connecting plate 6 are perpendicularly distributed and are integrally formed.

[0029] Both the first connecting plate 5 and the second connecting plate 6 have a first air guide plate 7 and a second air guide plate 8. The first connecting plate 5 is fixed to the inner wall of the silencing chamber 4. One side of the first air guide plate 7 and one side of the first connecting plate 5 are integrally formed, and the other side of the first connecting plate 5 and one side of the second air guide plate 8 are integrally formed. Both the second air guide plates 8 are inclined.

[0030] The first connecting plate 5, the first air guide plate 7 on the first connecting plate 5, the second air guide plate 8 on the first connecting plate 5, the second connecting plate 6, the first air guide plate 7 on the second connecting plate 6, the second air guide plate 8 on the second connecting plate 6, and the inner wall of the silencing chamber 4 form a bouncing space, so that the noise bounces within the bouncing space.

[0031] When noise travels into the anechoic chamber 4, it gradually dissipates through the bouncing space. The first air guide plate 7 includes a first slope 701 and a second slope 702. The first slope 701 and the second slope 702 are integrally formed. Both the first slope 701 and the second slope 702 are inclined, which increases the bouncing angle of the noise during the bouncing process, thereby lengthening the bouncing path and increasing the number of bouncing times of the noise, thus improving the noise dissipation speed.

[0032] An installation frame 9 is provided on the air outlet 3. The installation frame 9 has an air guide port 901 and six horizontally arranged exhaust ports 902. The air guide port 901 is connected to the air outlet 3. The installation frame 9 has an air storage chamber 903, which is connected to the air guide port 901 and the exhaust ports 902.

[0033] An installation frame 9 is provided on the air outlet 3. An air guide port 901 and an exhaust port 902 are provided on the installation frame 9. The air guide port 901 is connected to the air outlet 3. The installation frame 9 has an air storage chamber 903. The air storage chamber 903 is connected to the air guide port 901 and the exhaust port 902.

[0034] The gas storage chamber 903 has an upper support plate 904, a middle support plate 905 and a lower support plate 906, all of which are integrally formed with the gas storage chamber 903.

[0035] Several noise reduction holes 907 communicating with the gas storage chamber 903 are provided on the upper support plate 904, the middle support plate 905 and the lower support plate 906.

[0036] This causes the noise entering from the air outlet 3 to first enter the air storage chamber 903, and then pass through the noise reduction holes 907 on the upper support plate 904, the middle support plate 905, and the lower support plate 906 in sequence, and flow out from the exhaust port 902 respectively.

[0037] Since there are two noise reduction holes 907 on the upper support plate 904, three noise reduction holes 907 on the middle support plate 905, and four noise reduction holes 907 on the lower support plate 906, the noise will be effectively blocked and dispersed when passing through the upper support plate 904, the middle support plate 905, and the lower support plate 906. The exhaust port 902 has six outlets, which further diffuses the noise.

[0038] Working principle: Noise enters from the air inlet 2 and enters the silencing chamber 4. The noise is eliminated by bouncing in the assembly components. During the bouncing process, it will come into contact with the sound-absorbing cotton. Then the noise enters the air storage chamber 903 through the air outlet 3, and passes through the upper support plate 904, the middle support plate 905 and the lower support plate 906 in sequence. Finally, the noise is discharged from the exhaust port 902.

[0039] When noise travels into the anechoic chamber 4, it first collides with the assembly components. During the collision, the noise undergoes reflection, refraction, and scattering, causing it to bounce within the bounce space. During this bouncing process, the noise energy is gradually consumed and dispersed. Because an installation frame 9 is installed at the air outlet 3, the noise path is lengthened, further reducing the noise and thus improving the anechoic effect.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
