Description

Technical Field

[0001] The invention relates to the technical field of refrigerator compressor silencing equipment, in particular to a refrigerator compressor muffler. Background Art

[0002] While household refrigerators bring us convenience, they also bring us troubles. The impact of refrigerator unit noise on the environment and the room where it is used has been paid attention to. As the heart of the refrigerator, the compressor is the main source of refrigerator noise. The noise comes from the friction and collision between moving parts, or the eddy current generated by the gas during the flow process.

[0003] Among them, when the gas travels through the pipeline, due to the different diameters of the pipeline joints, the high-pressure gas drives the components to vibrate when passing through the air inlet, resulting in a large noise at the outlet end of the refrigerator compressor. To address the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a refrigerator compressor muffler, comprising an air inlet pipe, a side wall of the air inlet pipe is fixedly connected to a second air pressure ring, and an outer wall of the second air pressure ring is fixedly connected to an air outlet pipe;

[0005] The mounting mechanism comprises a mounting plate fixedly connected to the inner wall of the second air pressure ring, a sliding groove is provided on the inner wall of the mounting plate, an air inlet is provided on the inner wall of the sliding groove, and a flow assembly is fixedly connected to the inner wall of the mounting plate;

[0006] The compression mechanism comprises a sliding block slidably connected to the inner wall of the sliding groove, a plurality of exhaust ports are provided on the inner wall of the sliding block, a plurality of air pressure telescopic rods are fixedly connected to the side wall of the sliding block, a spring is fixedly connected to the side wall of the air pressure telescopic rod, a bell tube is fixedly connected to the side wall of the sliding block, and a mounting mechanism and a compression mechanism are arranged inside the equipment by utilizing the characteristic that the flow velocity is increased during the process of air flow transferring from a large diameter to a small diameter. Before use, the external air supply pipe is connected to the air inlet pipe, and the air outlet pipe is ensured to be connected to the air inlet of the compressor, and then the high-pressure gas enters the bell tube through the air inlet pipe, and is finally discharged to the outside through a plurality of exhaust ports, wherein the exhaust ports are as shown in the following figure. Figure 4 In the state shown, the air inlet end of the exhaust port is relatively large, while the air outlet end is relatively narrow. When the high-pressure gas passes through the exhaust port, the flow rate of the high-pressure gas increases. Through the application of the above-mentioned components, the total area of ​​the nozzle remains unchanged, and many exhaust ports are used instead. When the air flow passes through the small holes of the exhaust port, the spectrum of the jet noise will shift to high frequency or ultra-high frequency, which will significantly reduce the audible sound components in the spectrum, thereby reducing interference to people.

[0007] Preferably, the circulation component includes five pneumatic rings fixedly connected to the inner wall of the mounting plate, and three circulation tubes 1 are connected through the side walls of the five pneumatic rings. To address the problem that the exhaust port will generate high-frequency vibration while silencing the above-mentioned exhaust port, a pneumatic telescopic rod 1 and a spring 1 are arranged inside the device. When the exhaust port generates a sound wave due to high-frequency sound waves, the sound wave of the exhaust port will be transmitted to the sliding block, causing the sliding block to slide along the inner wall of the sliding groove. In this process, the spring 1 and the pneumatic telescopic rod 1 will limit the swing of the sliding block, and the spring 1 and the pneumatic telescopic rod 1 will absorb part of the vibration, thereby reducing the noise caused by friction between the mounting plate and the sliding block.

[0008] Preferably, the circulation component also includes a circulation tube 2 which is connected through the side wall of the pneumatic ring, a circulation tube 3 is connected through the two pneumatic rings, and a storage box is fixedly connected to the inner wall of the mounting plate. When the sliding block swings, the pneumatic telescopic rod 1 is pressurized, and the gas inside the pneumatic telescopic rod 1 will enter the interior of the pneumatic ring 2. When the mounting plate shifts to one end, the other end of the mounting plate will force the corresponding pneumatic telescopic rod 1 to extend, and multiple pneumatic telescopic rods 1 are connected through the inner wall of the pneumatic ring 2. The internal gas of the pressurized pneumatic telescopic rod 1 will pass through the pneumatic ring and enter the pneumatic telescopic rod 1 at the other end. Through the application of the above-mentioned components, the sliding amplitude of the sliding block can be effectively reduced during the sliding process, and the noise of friction of each component can be reduced.

[0009] Preferably, the circulation component includes a piston plate slidably connected to the inner wall of the storage box, a fixing frame is fixedly connected to the inner wall of the storage box, and a spring 2 is fixedly connected to the side wall of the fixing frame. The characteristic of the contraction of the above-mentioned pneumatic telescopic rod 1 to limit the swing of the sliding block is utilized, and a circulation tube 3 and a storage box are arranged inside the device. When the sliding block forces the internal gas of the pneumatic telescopic rod 1 to enter the inside of the pneumatic ring, multiple circulation tubes 3 and circulation tube 2 connect the multiple pneumatic rings and the storage box into a whole. After one of the pneumatic telescopic rods 1 is pressurized to inject gas into the whole, the gas will pass through The following paths are: 1. Entering the storage box through circulation tube 2; 2. The gas inside the pneumatic ring is transmitted to the remaining pneumatic rings through circulation tube 3; 3. The contracted pneumatic telescopic rod 1 transmits the gas through pneumatic ring 2 to the inside of the extended pneumatic telescopic rod 1. Through the application of the above components, when each sliding block vibrates, the sliding frequency, direction and speed of each sliding block are different, so as to avoid the exhaust port discharging gas while the frequency of the sound wave is gradually equal, resulting in frequency resonance inside the equipment, causing damage to internal components and affecting the noise reduction effect.

[0010] Preferably, one end of the spring 2 away from the fixing frame is fixedly connected to the side wall of the fixing frame, and the other end of the spring 1 is fixedly connected to the side wall of the sliding block, and a collecting component is provided on the side wall of the sliding block.

[0011] Preferably, the collecting assembly comprises a drainage groove provided on the side wall of the mounting plate, and the inner wall of the drainage groove is in continuous connection with the inner wall of the sliding groove.

[0012] Preferably, the collecting component also includes a plurality of drainage grooves provided on the side wall of the sliding block, and the end of the pneumatic telescopic rod away from the sliding block is through-connected to the inner wall of the pneumatic ring. The characteristic that the moisture inside the high-pressure gas will condense when the high-pressure gas passes through small holes is utilized, and a drainage groove is arranged inside the device. When the high-pressure gas is discharged outward through the narrow opening of the exhaust port, some water droplets will appear at the narrow opening of the exhaust port, and the condensed water droplets will slide downward along the inner wall of the drainage groove, and finally enter the sliding groove, and then be discharged outward through the drainage groove.

[0013] Preferably, the end of the second flow tube away from the air pressure ring is connected to the side wall of the storage box, and the end of the first flow tube away from the air pressure ring is connected to the inner wall of the second air pressure ring, wherein the position of the drainage groove overlaps with the exhaust port, so that the narrow mouth of the exhaust port appears as follows: Figure 8 The exhaust port is in an incomplete state. When water droplets condense on the exhaust port, the incomplete exhaust port will not be enough to keep the water droplets hanging on the outer wall of the exhaust port. The generated water droplets will quickly pass through the drainage groove into the sliding groove. Through the application of the above components, the integrity of the exhaust port is destroyed, and the residual water droplets are prevented from absorbing part of the frequency of the sound waves, thereby reducing the frequency of the sound waves and affecting the silencing effect.

[0014] The present invention has the following beneficial effects:

[0015] (1) The present invention utilizes the characteristic that the flow velocity increases during the process of air flow transferring from a large diameter to a small diameter. An installation mechanism and a compression mechanism are arranged inside the device. Before use, the external air delivery pipe is connected to the air inlet pipe, and the air outlet pipe is connected to the air inlet of the compressor. Subsequently, the high-pressure gas enters the bell tube through the air inlet pipe and is finally discharged to the outside through a plurality of exhaust ports, wherein the exhaust ports are as shown in FIG. Figure 4 In the state shown, the air inlet end of the exhaust port is relatively large, while the air outlet end is relatively narrow. When the high-pressure gas passes through the exhaust port, the flow rate of the high-pressure gas increases. Through the application of the above-mentioned components, the total area of ​​the nozzle remains unchanged, and many exhaust ports are used instead. When the air flow passes through the small holes of the exhaust port, the spectrum of the jet noise will shift to high frequency or ultra-high frequency, which will significantly reduce the audible sound components in the spectrum, thereby reducing interference to people.

[0016] (2) The present invention aims at the problem that the exhaust port will generate high-frequency vibration while silencing the above-mentioned exhaust port. A pneumatic telescopic rod 1 and a spring 1 are arranged inside the device. When the exhaust port generates a sound wave due to high-frequency sound waves, the sound wave of the exhaust port will be transmitted to the sliding block, causing the sliding block to slide along the inner wall of the sliding groove. During this process, the spring 1 and the pneumatic telescopic rod 1 will limit the swing of the sliding block, and the spring 1 and the pneumatic telescopic rod 1 will absorb part of the vibration, thereby reducing the noise caused by the friction between the mounting plate and the sliding block. In addition, when the sliding block swings, the pneumatic telescopic rod 1 is compressed, and the gas inside the pneumatic telescopic rod 1 will enter the inside of the pneumatic ring 2. When the mounting plate deviates to one end, the other end of the mounting plate will force the corresponding pneumatic telescopic rod 1 to extend. The multiple pneumatic telescopic rods 1 are connected to the inner wall of the pneumatic ring 2. The compressed gas inside the pneumatic telescopic rod 1 will pass through the pneumatic ring and enter the pneumatic telescopic rod 1 at the other end. Through the application of the above-mentioned components, the sliding amplitude of the sliding block can be effectively reduced during the sliding process, and the noise caused by the friction of each component can be reduced.

[0017] (3) The present invention utilizes the characteristic that the pneumatic telescopic rod 1 contracts to limit the swing of the sliding block, and a flow tube 3 and a storage box are arranged inside the device. When the sliding block forces the internal gas of the pneumatic telescopic rod 1 to enter the inside of the pneumatic ring, multiple flow tubes 3 and flow tube 2 connect the multiple pneumatic rings and the storage box into a whole. After one of the pneumatic telescopic rods 1 is pressurized to inject gas into the whole, the gas will pass through the following paths: 1. Enter the storage box through the flow tube 2; 2. The internal gas of the pneumatic ring is transmitted to the remaining pneumatic rings through the flow tube 3; 3. The contracted pneumatic telescopic rod 1 transmits the gas through the pneumatic ring 2 to the inside of the extended pneumatic telescopic rod 1. Through the application of the above-mentioned components, when each sliding block vibrates, the sliding frequency, direction and speed of each sliding block are different, so as to avoid that the frequency of the sound wave gradually becomes equal while the exhaust port discharges gas, resulting in frequency resonance inside the device, causing damage to internal components and affecting the noise reduction effect.

[0018] (4) The present invention utilizes the characteristic that when high-pressure gas passes through a small hole, the water inside the high-pressure gas will condense. A drainage groove is provided inside the device. When the high-pressure gas is discharged outward through the narrow opening of the exhaust port, some water droplets will appear at the narrow opening of the exhaust port. At this time, the condensed water droplets will slide downward along the inner wall of the drainage groove and eventually enter the inside of the sliding groove, and then be discharged outward through the drainage groove. The drainage groove and the exhaust port overlap, so that the narrow opening of the exhaust port appears as follows: Figure 8The exhaust port is in an incomplete state. When water droplets condense on the exhaust port, the incomplete exhaust port will not be enough to keep the water droplets hanging on the outer wall of the exhaust port. The generated water droplets will quickly pass through the drainage groove into the sliding groove. Through the application of the above components, the integrity of the exhaust port is destroyed, and the residual water droplets are prevented from absorbing part of the frequency of the sound waves, thereby reducing the frequency of the sound waves and affecting the silencing effect.

[0033] The compression mechanism 3 includes a sliding block 31 slidably connected to the inner wall of the sliding groove 22, a plurality of exhaust ports 32 are opened on the inner wall of the sliding block 31, a plurality of air pressure telescopic rods 33 are fixedly connected to the side wall of the sliding block 31, a spring 34 is fixedly connected to the side wall of the air pressure telescopic rod 33, and a bell tube 35 is fixedly connected to the side wall of the sliding block 31. By utilizing the characteristic of increased flow velocity during the transfer of air flow from a large diameter to a small diameter, a mounting mechanism 2 and a compression mechanism 3 are arranged inside the device. Before use, the external air supply pipe is connected to the air inlet pipe 1, and the air outlet pipe 12 is connected to the air inlet of the compressor. Subsequently, the high-pressure gas enters the bell tube 35 through the air inlet pipe 1, and is finally discharged to the outside through a plurality of exhaust ports 32, wherein the exhaust ports 32 are as shown in the following figure. Figure 4 In the state shown, the air inlet end of the exhaust port 32 is relatively large, while the air outlet end is relatively narrow. When the high-pressure gas passes through the exhaust port 32, the flow rate of the high-pressure gas increases. Through the application of the above-mentioned components, the total area of ​​the nozzle remains unchanged, and a lot of exhaust ports 32 are used instead. When the airflow passes through the small hole of the exhaust port 32, the spectrum of the jet noise will shift to high frequency or ultra-high frequency, so that the audible sound component in the spectrum is significantly reduced, thereby reducing interference to people.

[0034] For example 2, please refer to Figure 5-Figure 8The present invention is a refrigerator compressor silencer. On the basis of the first embodiment, the circulation component 4 includes five air pressure rings 41 fixedly connected to the inner wall of the mounting plate 21. The side walls of the five air pressure rings 41 are connected with three circulation pipes 42. In order to solve the problem that the exhaust port 32 will generate high-frequency vibration while the exhaust port 32 is silenced, an air pressure telescopic rod 33 and a spring 34 are arranged inside the device. When the exhaust port 32 is aligned due to high-frequency sound waves, the alignment of the exhaust port 32 will be transmitted to the sliding block 31, so that the sliding block 31 slides along the inner wall of the sliding groove 22. In this process, the spring 34 and the air pressure telescopic rod 33 will limit the swing of the sliding block 31, and the spring 34 and the air pressure telescopic rod 33 will absorb part of the vibration, thereby reducing the noise caused by friction between the mounting plate 21 and the sliding block 31.

[0035] The circulation component 4 also includes a circulation pipe 2 43 which is connected through the side wall of the pneumatic ring 41, a circulation pipe 3 44 is connected through the two pneumatic rings 41, and a storage box 45 is fixedly connected to the inner wall of the mounting plate 21. When the sliding block 31 swings, the pneumatic telescopic rod 1 33 is pressurized, and the gas inside the pneumatic telescopic rod 1 33 will enter the inside of the pneumatic ring 2 11. When the mounting plate 21 deviates to one end, the other end of the mounting plate 21 will force the corresponding pneumatic telescopic rod 1 33 to extend, and multiple pneumatic telescopic rods 1 33 are connected through the inner wall of the pneumatic ring 2 11. The pressurized gas inside the pneumatic telescopic rod 1 33 will pass through the pneumatic ring 11 and enter the pneumatic telescopic rod 1 33 at the other end. Through the application of the above-mentioned components, the sliding amplitude of the sliding block 31 can be effectively reduced during the sliding process, and the noise of friction between each component can be reduced.

[0036] The circulation assembly 4 includes a piston plate 46 slidably connected to the inner wall of the storage box 45, a fixing frame 47 is fixedly connected to the inner wall of the storage box 45, and a spring 2 48 is fixedly connected to the side wall of the fixing frame 47. By utilizing the characteristic that the contraction of the above-mentioned pneumatic telescopic rod 1 33 limits the swing of the sliding block 31, a circulation pipe 3 44 and a storage box 45 are arranged inside the device. When the sliding block 31 forces the gas inside the pneumatic telescopic rod 1 33 to enter the inside of the pneumatic ring 41, multiple circulation pipes 3 44 and circulation pipe 2 43 connect multiple pneumatic rings 41 and the storage box 45 into a whole. After one of the pneumatic telescopic rods 1 33 is pressurized to inject gas into the whole, The gas will pass through the following paths: 1. Enter the storage box 45 through the circulation tube 2 43; 2. The gas inside the air pressure ring 41 is transmitted to the other air pressure rings 41 through the circulation tube 3 44; 3. The contracted air pressure telescopic rod 1 33 transmits the gas through the air pressure ring 2 11 to the inside of the extended air pressure telescopic rod 1 33. Through the application of the above components, when each sliding block 31 vibrates, the sliding frequency, direction and speed of each sliding block 31 are different, so as to avoid that the frequency of the sound wave gradually becomes equal when the exhaust port 32 discharges gas, resulting in frequency resonance inside the equipment, causing damage to internal components and affecting the noise reduction effect.

[0037] One end of the second spring 48 away from the fixing frame 47 is fixedly connected to the side wall of the fixing frame 47 , and the other end of the first spring 34 is fixedly connected to the side wall of the sliding block 31 . The side wall of the sliding block 31 is provided with a collecting assembly 5 .

[0038] The collecting assembly 5 includes a drainage groove 51 formed on the side wall of the mounting plate 21 , and the inner wall of the drainage groove 51 is connected to the inner wall of the sliding groove 22 .

[0039] The collecting component 5 also includes a plurality of drainage grooves 52 provided on the side wall of the sliding block 31. The end of the pneumatic telescopic rod 33 away from the sliding block 31 is connected to the inner wall of the pneumatic ring 41. The drainage grooves 52 are arranged inside the device by utilizing the characteristic that when the high-pressure gas passes through small holes, the moisture inside the high-pressure gas will condense. When the high-pressure gas is discharged outward through the narrow opening of the exhaust port 32, some water droplets will appear at the narrow opening of the exhaust port 32. At this time, the condensed water droplets will slide downward along the inner wall of the drainage groove 52, and finally enter the interior of the sliding groove 22, and then be discharged outward through the drainage groove 51.

[0040] The end of the flow pipe 2 43 away from the air pressure ring 41 is connected to the side wall of the storage box 45, and the end of the three flow pipes 1 42 away from the air pressure ring 41 is connected to the inner wall of the air pressure ring 2 11, wherein the drainage groove 52 overlaps with the exhaust port 32, so that the narrow opening of the exhaust port 32 is as shown in FIG. Figure 8The exhaust port 32 is in an incomplete state, and when water droplets condense at the exhaust port 32, the incomplete exhaust port 32 will not be sufficient to allow the water droplets to hang on the outer wall of the exhaust port 32, and the generated water droplets will quickly pass through the drainage groove 52 into the sliding groove 22. Through the application of the above components, the integrity of the exhaust port 32 is destroyed, and the residual water droplets are prevented from absorbing the frequency of part of the sound waves, thereby reducing the frequency of the sound waves and affecting the silencing effect.

[0041] A specific application of this embodiment is: before use, the external air supply pipe is connected to the air inlet pipe 1, and the air outlet pipe 12 is connected to the air inlet of the compressor. Then, the high-pressure gas enters the bell tube 35 through the air inlet pipe 1, and is finally discharged to the outside through the multiple exhaust ports 32, wherein the exhaust ports 32 are as shown in FIG. Figure 4 In the state shown, the air inlet end of the exhaust port 32 is relatively large, while the air outlet end is relatively narrow. When the high-pressure gas passes through the exhaust port 32, the flow rate of the high-pressure gas increases. Through the application of the above-mentioned components, the total area of ​​the nozzle remains unchanged, and a lot of exhaust ports 32 are used instead. When the airflow passes through the small hole of the exhaust port 32, the spectrum of the jet noise will shift to high frequency or ultra-high frequency, so that the audible sound component in the spectrum is significantly reduced, thereby reducing interference to people.

[0042] In order to solve the problem that the exhaust port 32 will generate high-frequency vibration while silencing the above-mentioned exhaust port 32, a pneumatic telescopic rod 33 and a spring 34 are provided inside the device. When the exhaust port 32 generates a sound wave due to high-frequency sound waves, the sound wave of the exhaust port 32 will be transmitted to the sliding block 31, causing the sliding block 31 to slide along the inner wall of the sliding groove 22. In this process, the spring 34 and the pneumatic telescopic rod 33 will limit the swing of the sliding block 31, and the spring 34 and the pneumatic telescopic rod 33 will absorb part of the vibration, thereby reducing the noise caused by the friction between the mounting plate 21 and the sliding block 31. In addition, in the sliding block 3 When the pneumatic telescopic rod 1 swings, the pneumatic telescopic rod 1 33 is compressed, and the gas inside the pneumatic telescopic rod 1 33 will enter the inside of the pneumatic ring 2 11. When the mounting plate 21 deviates to one end, the other end of the mounting plate 21 will force the corresponding pneumatic telescopic rod 1 33 to extend, and the multiple pneumatic telescopic rods 1 33 are through-connected with the inner wall of the pneumatic ring 2 11. The compressed gas inside the pneumatic telescopic rod 1 33 will pass through the pneumatic ring 11 and enter the pneumatic telescopic rod 1 33 at the other end. Through the application of the above components, the sliding amplitude of the sliding block 31 can be effectively reduced during the sliding process, and the noise of the friction of each component can be reduced.

[0043] Taking advantage of the fact that the contraction of the above-mentioned pneumatic telescopic rod 33 limits the swing of the sliding block 31, a circulation tube 3 44 and a storage box 45 are arranged inside the device. When the sliding block 31 forces the gas inside the pneumatic telescopic rod 33 to enter the inside of the pneumatic ring 41, multiple circulation tubes 3 44 and circulation tube 2 43 connect multiple pneumatic rings 41 and the storage box 45 into a whole. After one of the pneumatic telescopic rods 33 is pressurized to inject gas into the whole, the gas will pass through the following paths: 1. Enter the storage box 45 through the circulation tube 2 43; 2. The gas inside the pneumatic ring 41 is transmitted to the remaining pneumatic rings 41 through the circulation tube 3 44; 3. The contracted pneumatic telescopic rod 33 transmits the gas through the pneumatic ring 2 11 to the inside of the extended pneumatic telescopic rod 33. Through the application of the above-mentioned components, each slide When the moving block 31 vibrates, the sliding frequency, direction and speed of each sliding block 31 are different, so as to avoid that the frequency of the sound waves gradually becomes equal while the exhaust port 32 discharges gas, resulting in frequency resonance inside the device, causing damage to internal components and affecting the noise reduction effect. When high-pressure gas passes through small holes, the moisture inside the high-pressure gas will condense. A drainage groove 52 is provided inside the device. When the high-pressure gas is discharged outward through the narrow mouth of the exhaust port 32, some water droplets will appear at the narrow mouth of the exhaust port 32. At this time, the condensed water droplets will slide downward along the inner wall of the drainage groove 52, and finally enter the sliding groove 22, and then be discharged outward through the drainage groove 51. The drainage groove 52 overlaps with the exhaust port 32, so that the narrow mouth of the exhaust port 32 appears as follows. Figure 8 The exhaust port 32 is in an incomplete state, and when water droplets condense at the exhaust port 32, the incomplete exhaust port 32 will not be sufficient to allow the water droplets to hang on the outer wall of the exhaust port 32, and the generated water droplets will quickly pass through the drainage groove 52 into the sliding groove 22. Through the application of the above components, the integrity of the exhaust port 32 is destroyed, and the residual water droplets are prevented from absorbing the frequency of part of the sound waves, thereby reducing the frequency of the sound waves and affecting the silencing effect.
