Description

Technical Field

[0001] This utility model relates to the field of air conditioning unit technology, and in particular to a noise reduction mechanism for air conditioning units. Background Technology

[0002] An air conditioning unit is an air handling device assembled from various air handling functional sections. When in actual use, the air conditioning unit will generate a lot of noise due to the vibration generated during its operation. Therefore, noise reduction mechanisms are needed to reduce the noise of the air conditioning unit during operation, thereby reducing the impact of noise on the living and working environment.

[0003] In an air conditioning unit noise reduction mechanism with announcement number CN220582712U, the air conditioning unit body is included, as well as four through holes opened on the piston plate. The four through holes are arranged in a ring array and are located near the edge of the piston plate. The damping tube is provided with a protective mechanism for protecting the piston plate when it is close to the bottom of the damping tube. The protective mechanism includes a protective ring slidably connected inside the damping tube and located between the damping tube and the piston plate. Under the protection of the protective mechanism, the through holes on the piston plate are blocked, so that the damping fluid cannot flow through the through holes, thereby preventing the piston plate from colliding with the bottom of the damping tube, reducing the wear of the piston plate during use, ensuring the normal service life of the damper, and further ensuring the vibration reduction and noise reduction effect of the air conditioning unit body.

[0004] However, the noise reduction mechanism of the above-mentioned air conditioning unit still has the following defects when in use: When the above-mentioned existing technology is used, the damping rod slides inside the damping tube, thereby causing the damping spring to deform under force, which facilitates the damping and noise reduction of the air conditioning unit. However, in actual use, the noise reduction effect of only using damping is poor. When the amplitude of vibration is large, noise will still be generated, which will affect the surrounding environment and life. Utility Model Content

[0005] The purpose of this utility model is to provide a noise reduction mechanism for air conditioning units, so as to solve the problem that the existing noise reduction mechanisms for air conditioning units have poor noise reduction effect during use, as mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a noise reduction mechanism for an air conditioning unit, comprising an air conditioning unit body, a rubber plate, and a base plate, wherein the bottom end of the air conditioning unit body is provided with a rubber plate, and the bottom end of the rubber plate is fixed with a base plate;

[0007] The outer side of the air conditioning unit body is provided with a sound-absorbing mechanism. The bottom plate is uniformly fixed with damping tubes, and each damping tube is fixed with a damping block. Each damping block is wrapped with a fixing spring, and one end of each fixing spring is fixed with a damping plate. Each damping plate is provided with a damping rod on one side.

An airflow duct is fixed on one side of the back of the air conditioning unit body, and a silencer is provided on one side of the airflow duct.

[0008] When using a noise reduction mechanism for an air conditioning unit according to this technical solution, the sound-absorbing mechanism can improve the noise reduction effect on the air conditioning unit itself during use, thereby effectively preventing the transmission of noise and reducing the impact of noise on the surrounding environment and life.

[0009] Preferably, the sound-absorbing mechanism includes a sound-absorbing plate disposed at the top of the damping tube, and the sound-absorbing plate has sound-insulating felt adhered inside, with a sound-absorbing layer disposed on one side of the sound-insulating felt.

[0010] Preferably, the sound-absorbing layer is disposed on one side of the sound-absorbing layer, the cross-section of the sound-absorbing layer is rectangular, and the material of the sound-absorbing layer is sound-absorbing cotton.

[0011] Preferably, the silencing mechanism includes a fixed tube, which is located on the outside of the airflow duct. Sound insulation cotton is adhered inside the fixed tube. A rotating rod is installed inside the sound insulation cotton, and a rotating block is fixed to the outside of the rotating rod. A dispersing plate is installed on the outside of each rotating block, and a fixing bolt passes through one side of the fixed tube.

[0012] Preferably, four dispersing plates are provided, and the four dispersing plates are arranged in a cross shape.

[0013] Preferably, the damping plates are provided in two sets, each set having multiple damping plates, and the cross-section of each of the multiple damping plates is circular, with the outer edges of the multiple damping plates slidingly attached to the inner wall of the damping block.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the noise reduction mechanism of this air conditioning unit not only improves the noise reduction effect, but also has the function of noise reduction;

[0016] By incorporating a sound-absorbing layer and working in conjunction with sound-insulating felt, the noise generated by the air conditioning unit can be absorbed. During the absorption process, the energy of the noise is consumed, and the sound-absorbing panel further reduces the noise generated by the air conditioning unit, thereby achieving the purpose of noise reduction and improving the noise reduction effect of the air conditioning unit to reduce the impact of noise on the surrounding environment and life.

[0017] By installing sound-absorbing panels to fix the fixed pipe to the airflow duct, when the airflow discharged from the air conditioning unit is introduced into the airflow duct, the dispersing plate rotates under the action of the rotating rod and rotating block, thereby dispersing the discharged airflow and reducing the airflow velocity to achieve the purpose of initial noise reduction. In addition, with the cooperation of sound insulation cotton, it is easy to absorb the noise generated by the airflow, thereby further achieving the purpose of noise reduction and reducing the propagation of noise.

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

[0026] Please see Figures 1-5 An embodiment of this utility model is provided: a noise reduction mechanism for an air conditioning unit, including an air conditioning unit body 1, a rubber plate 4, and a base plate 7. The bottom end of the air conditioning unit body 1 is provided with a rubber plate 4, and the bottom end of the rubber plate 4 is fixed with the base plate 7. A sound absorption mechanism 2 is provided on the outside of the air conditioning unit body 1.

[0027] The sound absorption mechanism 2 includes a sound absorption plate 203 and the sound absorption plate 203 is disposed at the top of the damping tube 5. The sound absorption plate 203 has a sound insulation felt 202 adhered inside, and a sound absorption layer 201 is disposed on one side of the sound insulation felt 202.

[0028] The sound-absorbing layer 201 is disposed on one side of the sound-absorbing layer 201. The cross-section of the sound-absorbing layer 201 is rectangular, and the material of the sound-absorbing layer 201 is sound-absorbing cotton.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, in use, the sound-absorbing layer 201, in conjunction with the sound-insulating felt 202 and the sound-absorbing panel 203, facilitates the absorption of noise generated by the operation of the air conditioning unit 1, thereby achieving the purpose of noise reduction.

[0030] The base plate 7 has damping tubes 5 evenly fixed inside, and damping blocks 12 are fixed inside each damping tube 5. A fixing spring 13 is wound around the outside of each damping block 12, and a damping plate 11 is fixed at one end of each fixing spring 13.

[0031] Two sets of damping plates 11 are provided, and each set of damping plates 11 has multiple damping plates 11. The cross-section of multiple damping plates 11 is circular, and the outer edge of multiple damping plates 11 slides against the inner wall of the damping block 14.

[0032] Specifically, such as Figure 4 As shown, during use, by setting the damping plate 11 to slide against the inner wall of the damping block 14, the self-vibration force generated by the reset of the shock-absorbing spring 3 and the fixed spring 13 can be buffered, thereby reducing the impact of the self-vibration force on the air conditioning unit body 1.

[0033] A damping rod 6 is provided on one side of the damping plate 11. A fixing plate 10 is welded to one side of the damping tube 5 and the damping rod 6. A damping spring 3 is fixed between the two fixing plates 10. A damping block 14 is provided on the inner wall of the damping tube 5.

[0034] There are two sets of damping blocks 14, and each set has multiple damping blocks 14, and the cross-section of multiple damping blocks 14 is annular.

[0035] Specifically, such as Figure 4 As shown, during use, multiple damping blocks 14, in cooperation with the damping plate 11, buffer the reset shock-absorbing spring 3 and the fixed spring 13, thereby ensuring the stability of the air conditioning unit body 1 during use.

[0036] An airflow duct 8 is fixed on one side of the back of the air conditioning unit body 1, and a silencer 9 is provided on one side of the airflow duct 8.

[0037] The silencing mechanism 9 includes a fixed tube 901, which is located on the outside of the airflow duct 8. Sound insulation cotton 902 is adhered inside the fixed tube 901. A rotating rod 905 is installed inside the sound insulation cotton 902. A rotating block 906 is fixed on the outside of the rotating rod 905. A dispersing plate 904 is installed on the outside of the rotating block 906. A fixing bolt 903 passes through one side of the fixed tube 901.

[0038] There are four dispersing plates 904, which are arranged in a cross shape.

[0039] Specifically, such as Figure 2 , Figure 3 , Figure 5 As shown, during use, the airflow is dispersed by the rotating motion of the air-dispersing plate 904, which facilitates the initial noise reduction operation. Furthermore, the sound insulation cotton 902 further absorbs the noise generated by the airflow, thereby improving the noise reduction effect and reducing the propagation of noise.

[0040] Working principle: When this utility model is in use, vibration force is first generated during the operation of the air conditioning unit body 1. This vibration force is transmitted to the rubber plate 4, causing the fixed plate 10 to move downward. While the fixed plate 10 is moving downward, it squeezes the shock-absorbing spring 3, causing the shock-absorbing spring 3 to be compressed by the squeezing force. At the same time, the fixed plate 10 moves downward, causing the shock-absorbing rod 6 to move downward synchronously, causing the damping plate 11 to move downward synchronously, and then the shock-absorbing block 12 to be compressed by the squeezing force. Through the above operation, the air conditioning unit body 1 can be vibration-damped and noise-reduced. In addition, the damping plate 11, with the cooperation of the damping block 14, can buffer the self-vibration force generated by the reset of the shock-absorbing spring 3 and the fixed spring 13, thereby avoiding the impact of the self-vibration force of the shock-absorbing spring 3 and the fixed spring 13 on the air conditioning unit body 1, so as to ensure the service life of the air conditioning unit body 1.

[0041] Secondly, by setting a sound-absorbing layer 201, the material of which is sound-absorbing cotton, which has a good sound absorption effect, it can absorb the noise generated by the air conditioning unit body 1 during operation. In addition, with the cooperation of sound insulation felt 202, it can further absorb the noise generated by the air conditioning unit body 1 during operation. At the same time, by setting a sound-absorbing panel 203, the surface and interior of which have many small holes, it can further absorb the noise generated by the air conditioning unit body 1 during operation. Through the above operations, the noise reduction effect of the air conditioning unit body 1 is improved, thereby reducing the transmission of noise and improving its practicality.

[0042] Finally, when the air conditioning unit 1 exhausts air, the airflow enters the interior of the fixed pipe 901 through the airflow pipe 8. When the airflow enters the interior of the fixed pipe 901, it first contacts the dispersing plate 904. Under the action of the rotating block 906 and the rotating rod 905, the dispersing plate 904 rotates, thereby dispersing the airflow and slowing down the airflow speed, thus initially achieving the purpose of noise reduction. Furthermore, by providing sound insulation cotton 902, when the airflow flows inside the fixed pipe 901, the sound insulation cotton 902 can absorb and alleviate the noise generated by the airflow, thereby further achieving the purpose of noise reduction. Through the above operations, its noise reduction effect can be further improved.
