Description

Technical Field

[0001] The present invention relates to the technical field of noise reduction equipment for refrigerator compressors, and particularly to a silencer for a refrigerator compressor. Background Art

[0002] Household refrigerator appliances bring us convenience while also bringing us troubles. The noise of refrigerator unit equipment has been taken seriously by everyone for its impact on the environment and the using room. As the heart of the refrigerator, the compressor is the main source of noise in refrigerator appliances. Its noise comes from the mutual friction and impact between moving parts, or the eddy current generated during the flow of gas.

[0003] Among them, when the gas shuttles through the pipeline, due to the different diameters at the pipeline connection, when the high-pressure gas passes through the air inlet, the high-pressure gas drives the components to vibrate, resulting in relatively large noise at the air outlet end of the refrigerator compressor. In view of the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a silencer for a refrigerator compressor, which includes an intake pipe. A second air pressure ring is fixedly connected to the side wall of the intake pipe, and an outlet pipe is fixedly connected to the outer wall of the second air pressure ring;

[0005] An installation mechanism, which includes an installation disk fixedly connected to the inner wall of the second air pressure ring. A sliding groove is provided on the inner wall of the installation disk, an air inlet is provided on the inner wall of the sliding groove, and a circulation component is fixedly connected to the inner wall of the installation disk;

[0006] A compression mechanism, which includes 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 first air pressure telescopic rods are fixedly connected to the side wall of the sliding block. A first spring is fixedly connected to the side wall of the first air pressure telescopic rod. A horn pipe is fixedly connected to the side wall of the sliding block. Utilizing the characteristic that the flow rate increases during the transfer of air flow from a large diameter to a small diameter, an installation mechanism and a compression mechanism are provided inside the equipment. Before use, connect the external air delivery pipe to the intake pipe and ensure that the outlet pipe is connected to the air inlet of the compressor. Subsequently, the high-pressure gas enters the inside of the horn pipe through the intake pipe and is finally discharged outward through a plurality of exhaust ports. Among them, the exhaust ports are in the state as Figure 4 shown. The intake end of the exhaust port is larger, while the outlet end is narrower. 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 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 frequency spectrum of the jet noise will shift to high frequency or ultra-high frequency, significantly reducing the audible sound component in the frequency spectrum, thereby reducing the interference to people.

[0007] Preferably, the circulation component includes five air pressure rings fixedly connected to the inner wall of the mounting disc. Three first circulation pipes are connected through the side walls of the five air pressure rings. While silencing the above exhaust port, the exhaust port will also generate a problem of high-frequency vibration. An air pressure telescopic rod one and a first spring are arranged inside the device. When the exhaust port is targeted due to high-frequency sound waves, the targeting 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 first spring and the air pressure telescopic rod one will limit the swing of the sliding block, and the first spring and the air pressure telescopic rod one will absorb part of the vibration, reducing the noise generated by the friction between the mounting disc and the sliding block.

[0008] Preferably, the circulation component further includes a second circulation pipe connected through the side wall of the air pressure ring. A third circulation pipe is connected through between two air pressure rings. A storage box is fixedly connected to the inner wall of the mounting disc. When the sliding block swings, the air pressure telescopic rod one is pressed, and the gas inside the air pressure telescopic rod one will enter the second air pressure ring. When the mounting disc deflects towards one end, the other end of the mounting disc will force the corresponding air pressure telescopic rod one to extend. The plurality of air pressure telescopic rods one and the inner wall of the second air pressure ring are connected through. The gas inside the pressed air pressure telescopic rod one will enter the other air pressure telescopic rod one through the air pressure ring. Through the application of the above components, when the sliding block slides, the sliding amplitude of the sliding block can be effectively reduced, and the noise generated by the 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. A second spring is fixedly connected to the side wall of the fixing frame. Using the characteristic that the contraction of the above air pressure telescopic rod one restricts the swing of the sliding block, a third circulation pipe and a storage box are arranged inside the device. When the sliding block forces the gas inside the air pressure telescopic rod one to enter the air pressure ring, the plurality of third circulation pipes and the second circulation pipe connect the plurality of air pressure rings and the storage box into a whole. After one of the air pressure telescopic rods one is pressed and fills the gas into the whole, the gas will pass through the following paths: one, enter the storage box through the second circulation pipe; two, the gas inside the air pressure ring is transmitted to the remaining air pressure rings through the third circulation pipe; three, the contracted air pressure telescopic rod one transmits the gas to the inside of the extended air pressure telescopic rod one through the second air pressure ring. Through the application of the above components, when each sliding block vibrates, the sliding frequencies, directions, and speeds of each sliding block are different, avoiding the phenomenon that the frequencies of the sound waves gradually become equal while the gas is discharged from the exhaust port, resulting in frequency resonance inside the device, damaging the internal components, and affecting the noise reduction effect.

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

[0011] Preferably, the collection component includes a drain groove opened on the side wall of the mounting disc, and the inner wall of the drain groove is connected to the inner wall of the sliding groove in a through manner.

[0012] Preferably, the collection component further includes a plurality of drainage grooves opened on the side wall of the sliding block. One end of the pneumatic telescopic rod away from the sliding block is connected to the inner wall of the pneumatic ring in a through manner. By using the characteristic that moisture in the high-pressure gas will condense when the high-pressure gas passes through small holes, drainage grooves are 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 position of the exhaust port. At this time, the condensed water droplets will slide downward along the inner wall of the drainage groove and finally enter the inside of the sliding groove, and then be discharged outward through the drain groove.

[0013] Preferably, the end of the second flow pipe away from the pneumatic ring is connected to the side wall of the storage tank in a through manner. One end of the three first flow pipes away from the pneumatic ring is connected to the inner wall of the second pneumatic ring. Among them, the position of the drainage groove overlaps with the exhaust port, so that the narrow opening of the exhaust port presents a state as shown in Figure 8 , and at this time, the discharge port of the exhaust port is in a defective state. When water droplets condense at the exhaust port, the defective exhaust port will not be sufficient to make the water droplets stay on the outer wall of the exhaust port, and the generated water droplets will quickly enter the inside of the sliding groove through the drainage groove. Through the application of the above components, the integrity of the exhaust port is damaged, avoiding the remaining water droplets from absorbing part of the sound wave frequency, reducing the sound wave frequency, and affecting the sound absorption 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 transfer of air flow from a large diameter to a small diameter, and an installation mechanism and a compression mechanism are provided inside the device. Before use, the external air pipe is connected to the intake pipe, and it is ensured that the outlet pipe is connected to the intake port of the compressor. Subsequently, the high-pressure gas enters the inside of the horn pipe through the intake pipe and is finally discharged outward through a plurality of exhaust ports. Among them, the exhaust port presents a state as shown in Figure 4 , the intake end of the exhaust port is relatively large, and the outlet end is relatively narrow. When the high-pressure gas passes through the exhaust port, the flow velocity of the high-pressure gas increases. Through the application of the above 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 frequency spectrum of the jet noise will shift to high frequency or ultra-high frequency, and the audible sound component in the frequency spectrum will be significantly reduced, thereby reducing the interference to people.

[0016] (2) When the present invention silences the exhaust port, the exhaust port will also generate high-frequency vibrations. Inside the device, there is a pneumatic telescopic rod 1 and a spring 1. When the exhaust port is targeted by high-frequency sound waves, the targeting 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 jitter, reducing the noise generated 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 pneumatic ring 2. When the mounting plate deviates towards 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 and the inner wall of the pneumatic ring 2 are connected in a through manner, and the gas inside the compressed pneumatic telescopic rod 1 will enter the other pneumatic telescopic rod 1 through the pneumatic ring. Through the application of the above components, when the sliding block slides, the sliding amplitude of the sliding block can be effectively reduced, and the noise generated by the friction of each component can be reduced.

[0017] (3) By utilizing the characteristic that the contraction of the pneumatic telescopic rod 1 restricts the swing of the sliding block, a circulation pipe 3 and a storage tank are arranged inside the device. When the sliding block forces the gas inside the pneumatic telescopic rod 1 to enter the pneumatic ring, the multiple circulation pipes 3 and the circulation pipe 2 connect multiple pneumatic rings and the storage tank into a whole. After one of the pneumatic telescopic rods 1 is compressed and fills the gas into the whole, the gas will pass through the following paths: First, it enters the storage tank through the circulation pipe 2; second, the gas inside the pneumatic ring is transmitted to the other pneumatic rings through the circulation pipe 3; third, the compressed pneumatic telescopic rod 1 transmits the gas to the inside of the extended pneumatic telescopic rod 1 through the pneumatic ring 2. Through the application of the above components, when each sliding block vibrates, the sliding frequencies, directions, and speeds of each sliding block are different, avoiding the phenomenon that the frequencies of sound waves gradually become equal while the gas is discharged from the exhaust port, resulting in frequency resonance inside the device, damaging the internal components, and affecting the noise reduction effect.

[0018] (4) By utilizing the characteristic that moisture inside high-pressure gas will condense when the high-pressure gas passes through small holes, 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. At this time, 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 drain groove. The position of the drainage groove overlaps with the exhaust port, making the narrow opening of the exhaust port present as Figure 8At this time, the discharge port of the exhaust port is in a defective state. When water droplets condense at the exhaust port, the defective exhaust port will not be sufficient to allow the water droplets to stay on the outer wall of the exhaust port. The generated water droplets will quickly enter the inside of the sliding groove through the drainage groove. Through the application of the above components, the integrity of the exhaust port is damaged, preventing the remaining water droplets from absorbing part of the sound wave frequency, reducing the sound wave frequency, and affecting the sound absorption effect.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

A sliding groove 22 is opened on the inner wall of the installation disk 21, an air inlet 23 is opened on the inner wall of the sliding groove 22, and a circulation component 4 is fixedly connected to the inner wall of the installation disk 21;

[0033] A compression mechanism 3, the compression mechanism 3 includes a sliding block 31 slidably connected to the inner wall of the sliding groove 22.

A plurality of first air pressure telescopic rods 33 are fixedly connected to the side wall of the sliding block 31. A first spring 34 is fixedly connected to the side wall of the first air pressure telescopic rod 33. A horn pipe 35 is fixedly connected to the side wall of the sliding block 31. Utilizing the characteristic that the flow velocity increases during the transfer of air flow from a large diameter to a small diameter, an installation mechanism 2 and a compression mechanism 3 are provided inside the device. Before use, an external air pipe is connected to the intake pipe 1, and it is ensured that the outlet pipe 12 is connected to the air inlet of the compressor. Subsequently, high-pressure gas enters the horn pipe 35 through the intake pipe 1 and is finally discharged outward through a plurality of exhaust ports 32. Among them, the exhaust ports 32 are in the state as Figure 4 shown. The intake end of the exhaust port 32 is larger, and the outlet end is narrower. When the high-pressure gas passes through the exhaust port 32, the flow velocity of the high-pressure gas increases. Through the application of the above components, the total area of the nozzle remains unchanged, and a plurality of exhaust ports 32 are used instead. When the air flow passes through the small holes of the exhaust port 32, the frequency spectrum of the jet noise will shift to high frequency or ultra-high frequency, significantly reducing the audible sound component in the frequency spectrum, thereby reducing the interference to people.

[0034] Embodiment 2. Please refer to Figures 5 - 8, the present invention is a silencer for a refrigerator compressor. Based on the first embodiment, the circulation component 4 includes five air pressure rings 41 fixedly connected to the inner wall of the mounting plate 21. Three first circulation pipes 42 are connected through the side walls of the five air pressure rings 41. While silencing the exhaust port 32, the exhaust port 32 will also generate a problem of high-frequency vibration. An air pressure telescopic rod 33 and a first spring 34 are provided inside the device. When the exhaust port 32 is targeted due to high-frequency sound waves, the targeting 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. During this process, the first spring 34 and the air pressure telescopic rod 33 will limit the swing of the sliding block 31, and the first spring 34 and the air pressure telescopic rod 33 will absorb part of the vibration, reducing the noise generated by the friction between the mounting plate 21 and the sliding block 31;

[0035] The circulation component 4 further includes a second circulation pipe 43 connected through the side wall of the air pressure ring 41, and a third circulation pipe 44 is connected through between two air pressure rings 41. A storage tank 45 is fixedly connected to the inner wall of the mounting plate 21. When the sliding block 31 swings, the air pressure telescopic rod 33 is compressed, and the gas inside the air pressure telescopic rod 33 will enter the second air pressure ring 11. When the mounting plate 21 deflects towards one end, the other end of the mounting plate 21 will force the corresponding air pressure telescopic rod 33 to extend. The multiple air pressure telescopic rods 33 are connected through to the inner wall of the second air pressure ring 11, and the gas inside the compressed air pressure telescopic rod 33 will pass through the air pressure ring 11 and enter the air pressure telescopic rod 33 at the other end. Through the application of the above components, when the sliding block 31 slides, the sliding amplitude of the sliding block 31 can be effectively reduced, and the noise generated by the friction of each component can be reduced.

[0036] The circulation component 4 includes a piston plate 46 slidably connected to the inner wall of the storage tank 45. A fixed frame 47 is fixedly connected to the inner wall of the storage tank 45. A second spring 48 is fixedly connected to the side wall of the fixed frame 47. By utilizing the characteristic that the contraction of the first pneumatic telescopic rod 33 restricts the swing of the sliding block 31, a third circulation pipe 44 and a storage tank 45 are arranged inside the device. When the sliding block 31 forces the gas inside the first pneumatic telescopic rod 33 to enter the pneumatic ring 41, multiple third circulation pipes 44 and a second circulation pipe 43 connect multiple pneumatic rings 41 and the storage tank 45 into a whole. After one of the first pneumatic telescopic rods 33 is pressurized and fills the gas into the whole, the gas will pass through the following paths: First, it enters the storage tank 45 through the second circulation pipe 43; second, the gas inside the pneumatic ring 41 is transmitted to the remaining pneumatic rings 41 through the third circulation pipe 44; third, the contracted first pneumatic telescopic rod 33 transmits the gas to the inside of the extended first pneumatic telescopic rod 33 through the second pneumatic ring 11. Through the application of the above components, when each sliding block 31 vibrates, the sliding frequencies, directions, and speeds of each sliding block 31 are different, avoiding the phenomenon that the frequencies of sound waves gradually become equal while the gas is discharged from the exhaust port 32, resulting in frequency resonance inside the device, damaging the internal components, and affecting the noise reduction effect.

[0037] One end of the second spring 48 away from the fixed frame 47 is fixedly connected to the side wall of the fixed frame 47. The other end of the first spring 34 is fixedly connected to the side wall of the sliding block 31. A collection component 5 is provided on the side wall of the sliding block 31.

[0038] The collection component 5 includes a liquid discharge groove 51 opened on the side wall of the mounting plate 21, and the inner wall of the liquid discharge groove 51 is connected to the inner wall of the sliding groove 22 in a penetrating manner.

[0039] The collection component 5 further includes a plurality of drainage grooves 52 opened on the side wall of the sliding block 31. One end of the first pneumatic telescopic rod 33 away from the sliding block 31 is connected to the inner wall of the pneumatic ring 41 in a penetrating manner. By utilizing the characteristic that moisture in the high-pressure gas will condense when the high-pressure gas passes through small holes, drainage grooves 52 are arranged inside the device. 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 position 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 inside of the sliding groove 22, and then be discharged outward through the liquid discharge groove 51.

[0040] One end of the second circulation pipe 43 away from the pneumatic ring 41 is connected to the side wall of the storage tank 45 in a penetrating manner. One end of the three first circulation pipes 42 away from the pneumatic ring 41 is connected to the inner wall of the second pneumatic ring 11 in a penetrating manner. Among them, the position of the drainage groove 52 overlaps with the exhaust port 32, so that the narrow opening of the exhaust port 32 presents as Figure 8At this time, the outlet of the exhaust port 32 is in a defective state. When water droplets condense on the exhaust port 32, the defective exhaust port 32 will not be sufficient to hold the water droplets on the outer wall of the exhaust port 32. The generated water droplets will quickly enter the inside of the sliding groove 22 through the drainage groove 52. Through the application of the above components, the integrity of the exhaust port 32 is damaged, preventing the remaining water droplets from absorbing part of the sound wave frequency, reducing the sound wave frequency, and affecting the sound absorption effect.

[0041] A specific application of this embodiment is as follows: Before use, connect the external gas pipeline to the intake pipe 1 and ensure that the outlet pipe 12 is connected to the intake port of the compressor. Subsequently, high-pressure gas enters the inside of the horn pipe 35 through the intake pipe 1 and finally discharges outward through a plurality of exhaust ports 32. Among them, the exhaust port 32 presents a state as Figure 4 shown. The intake end of the exhaust port 32 is larger, and the outlet end is narrower. When high-pressure gas passes through the exhaust port 32, the flow rate of the high-pressure gas increases. Through the application of the above components, the total area of the nozzle remains unchanged, and many exhaust ports 32 are used instead. When the air flow passes through the small holes of the exhaust port 32, the frequency spectrum of the jet noise will shift to high frequency or ultra-high frequency, significantly reducing the audible sound component in the frequency spectrum, thereby reducing the interference to people.

[0042] Regarding the problem that the exhaust port 32 generates high-frequency vibrations while silencing, a pneumatic telescopic rod 33 and a spring 34 are provided inside the device. When the exhaust port 32 generates vibrations due to high-frequency sound waves, the vibrations 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. During 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 vibrations, reducing the noise generated by friction between the mounting plate 21 and the sliding block 31; in addition, when the sliding block 31 swings, the pneumatic telescopic rod 33 is compressed, and the gas inside the pneumatic telescopic rod 33 will enter the pneumatic ring 11 inside. When the mounting plate 21 offsets to one end, the other end of the mounting plate 21 will force the corresponding pneumatic telescopic rod 33 to extend. A plurality of pneumatic telescopic rods 33 are connected through the inner wall of the pneumatic ring 11, and the gas inside the compressed pneumatic telescopic rod 33 will pass through the pneumatic ring 11 and enter the pneumatic telescopic rod 33 at the other end. Through the application of the above components, when the sliding block 31 slides, the sliding amplitude of the sliding block 31 can be effectively reduced, reducing the noise generated by the friction of each component.

[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.
